DoubleVerify sets vote on $13.60-per-share buyout

Q: What are DV stockholders being offered in the Neptune BidCo merger?

Stockholders will receive $13.60 in cash per share of DoubleVerify common stock, without interest and subject to required withholding tax, for each share held immediately before the Effective Time, unless they properly exercise and preserve appraisal rights under Section 262 of the DGCL.

Q: How does the $13.60 offer for DV compare to recent trading prices?

The $13.60 per-share Merger Consideration represents a 22%, 30% and 30% premium to the 30-, 60- and 90-trading-day volume-weighted average prices of DoubleVerify stock, respectively, for the periods ending August 5, 2026, the last trading day before the deal announcement.

Q: What approvals are required for the DoubleVerify (DV) merger to close?

Closing requires the affirmative vote of a majority of outstanding shares entitled to vote, expiration or termination of the HSR Act waiting period, specified foreign antitrust clearances in Australia, Cyprus, Germany and Morocco, and satisfaction of other customary conditions, including no continuing Material Adverse Effect.

Q: Do DV stockholders have appraisal rights in this merger?

Yes. Stockholders who do not vote in favor, who properly demand appraisal and comply with Section 262 of the DGCL, and who continuously hold their shares through the Effective Time may seek a court-determined “fair value,” which could be more than, equal to, or less than $13.60 per share.

Q: How will DV equity awards be treated in the merger?

In-the-money vested options and vested RSUs/PSUs will be cashed out based on $13.60 per underlying share. Unvested in-the-money options, RSUs and certain PSUs convert into cash replacement awards that vest on original schedules, with acceleration upon qualifying termination within 12 months after closing or upon the holder’s death.

Rhea-AI Filing Summary

DoubleVerify Holdings, Inc. (DV) has called a virtual special meeting for stockholders to vote on a proposed cash acquisition by Neptune BidCo US Inc., an affiliate of Elliott Investment Management and Brookfield Asset Management. Under the Agreement and Plan of Merger dated August 6, 2026, Wallace Merger Sub Inc. will merge into DoubleVerify, which will become a wholly owned subsidiary of Parent.

If completed, each share of DoubleVerify common stock will be converted into the right to receive $13.60 in cash per share, without interest and subject to withholding taxes, and the stock will be delisted from the NYSE and deregistered under the Exchange Act. The board, acting on a unanimous recommendation from a special committee of independent directors and supported by a fairness opinion from PJT Partners, unanimously recommends voting FOR the merger, the advisory compensation proposal, and a possible adjournment. The deal is backed by about $2.332 billion of financing, including debt and $200 million of equity commitments, and is subject to stockholder approval, antitrust and foreign merger clearances, and other customary conditions. Stockholders who do not vote in favor may seek appraisal of the “fair value” of their shares under Delaware law if they follow the required procedures.

Filing Explained

The preliminary filing confirms no closing yet and adds that approval requires a majority of outstanding shares, with 11.8% committed support.

This PREM14A is a proxy statement presenting matters for stockholder approval, rather than a completed merger. The filing leaves the special-meeting and record dates as placeholders, so the proposed cash conversion and removal of public-company ownership remain subject to a future vote and other closing conditions.

Approval of the merger proposal requires affirmative votes from holders of a majority of the outstanding shares entitled to vote; abstentions and failures to vote have the same effect as votes against that proposal. Supporting stockholders holding approximately 11.8% of the outstanding shares have agreed to vote for the merger.

If the merger reaches the Effective Time, vested in-the-money options and vested restricted or earned performance units are generally cashed out, while unvested awards become cash awards subject to their existing vesting terms; underwater options are canceled for no consideration.

The filing states that Parent’s financing is not a condition to closing, while specified termination circumstances could require DoubleVerify to pay a $60 million termination fee. The next state-changing disclosures are the completed meeting details, the stockholder vote, regulatory clearances and, ultimately, a certificate of merger; until then, no cash exchange, delisting or deregistration has occurred.

6 terms

Merger Consideration financial

"each share of Company Common Stock ... will be automatically converted into ... $13.60 in cash"

Merger consideration is the total payment a company or buyer offers to shareholders of a target company in exchange for combining the two businesses, and can include cash, shares in the surviving company, debt assumption, or a mix of these. Investors care because the form and amount affect the deal’s value, tax consequences, immediate cash received versus future ownership, and the risk and upside of holding new shares — similar to choosing between cash now or stock that could grow later.

Appraisal Rights regulatory

"stockholders ... have the right to seek an appraisal of the “fair value” of their shares"

A legal right that lets shareholders who dislike the price or terms of a buyout, merger or other major corporate change ask for an independent determination of the fair value of their shares instead of accepting the deal price. Think of it like asking a neutral referee to set the payout if you believe the offered price is too low. For investors, appraisal rights can provide a way to recover a higher cash value but can be slow, costly and create uncertainty around deal outcomes.

Superior Proposal financial

"such Acquisition Proposal constitutes a Superior Proposal"

A superior proposal is a competing offer to buy or merge with a company that is materially better than an existing deal, typically offering higher cash, stronger terms, or fewer conditions. It matters to investors because it can raise the expected payout or change deal certainty—like getting a higher bid at an auction, a superior proposal can increase share value or prompt renegotiation of the transaction.

Termination Fee financial

"DoubleVerify may be required to pay Parent a termination fee in the amount of $60,000,000"

A termination fee is a payment required if one party ends a contract before its agreed-upon end date. It acts like a penalty or compensation to the other party for canceling early, similar to a fee you might pay for breaking a lease or canceling a service contract. For investors, it matters because it can influence a company's decisions and financial obligations related to ending agreements prematurely.

Non-Solicitation regulatory

"DoubleVerify has agreed not to ... solicit or knowingly facilitate or encourage any discussions"

A non-solicitation clause is a contractual promise that one party will not actively try to lure away another party’s employees, customers, or suppliers. For investors, it signals protection of a company’s workforce and client base after a deal or partnership—reducing the risk that key staff or revenue sources will be poached and therefore helping preserve the business’s value, predictability, and post-transaction earnings. Think of it as an agreement not to knock on a neighbor’s door to take their business or team.

What happens to DV shares and listing if the merger is completed?

At closing, all DV common shares (other than excluded and properly perfected appraisal shares) will be converted into the right to receive the $13.60 cash Merger Consideration.

What fees apply if the DoubleVerify (DV) merger agreement is terminated?

Do DV stockholders have appraisal rights in this merger?

Yes. Stockholders who do not vote in favor, who properly demand appraisal and comply with Section 262 of the DGCL, and who continuously hold their shares through the Effective Time may seek a court-determined “fair value,” which could be more than, equal to, or less than $13.60 per share.

PRELIMINARY PROXY STATEMENT SUBJECT TO COMPLETION, DATED
SEPTEMBER 11, 2026

DoubleVerify Holdings, Inc.
462 Broadway
New York, New York 10013

Dear Stockholders:

You are cordially invited to attend a special meeting (including any adjournments or postponements thereof, the “Special Meeting”) of stockholders of DoubleVerify Holdings, Inc., a Delaware corporation (“DoubleVerify,” or the “Company”), to be held virtually on [•], at [•] a.m. Eastern Time. The Company’s stockholders will be able to virtually attend and vote at the Special Meeting via the Internet at www.virtualshareholdermeeting.com/DV2026SM. You will not be able to attend the Special Meeting physically in person. If you plan to attend the Special Meeting online, please follow the instructions in the accompanying proxy statement. For purposes of attendance at the Special Meeting, all references in the enclosed proxy statement to “present” shall mean virtually present at the Special Meeting.

At the Special Meeting, you will be asked to consider and vote on, among other things, a proposal to adopt the Agreement and Plan of Merger, dated August 6, 2026 (as the same may be amended, modified or supplemented from time to time in accordance with its terms, the “Merger Agreement”), by and among DoubleVerify, Neptune BidCo US Inc., a Delaware corporation (“Parent”), and Wallace Merger Sub Inc., a Delaware corporation and a direct, wholly owned subsidiary of Parent (“Merger Sub”). Parent is the parent company of the Nielsen Company (US), LLC, and is an affiliate of funds managed by Elliott Investment Management L.P. and Brookfield Asset Management Ltd.

Upon the terms and subject to the conditions of the Merger Agreement, Merger Sub will merge with and into DoubleVerify, and the separate corporate existence of Merger Sub will thereupon cease, with DoubleVerify surviving the merger and continuing as the surviving corporation (the “Surviving Corporation”) and a wholly owned subsidiary of Parent (the “Merger”). If the Merger is completed, as of immediately following the Effective Time (as defined below), you will be entitled to receive an amount in cash equal to $13.60, without interest and subject to deduction for any required withholding tax, for each share of DoubleVerify’s common stock, par value $0.001 per share (the “Company Common Stock”) that you own as of immediately prior to the effective time of the Merger (unless you have properly and validly exercised your appraisal rights in accordance with Section 262 of the General Corporation Law of the State of Delaware (“Section 262 of the DGCL”)).

DoubleVerify’s Board of Directors (the “Company Board”) formed a special committee of the Company Board comprised solely of independent and disinterested directors (the “Special Committee”) to, among other things, review, evaluate and negotiate the Merger Agreement and the Transactions contemplated thereby, with the assistance of its own independent financial and legal advisors and, where appropriate, the Company’s management.

The Company Board, acting on the unanimous recommendation of the Special Committee, has (i) determined that the Merger Agreement, the Merger and the other Transactions are advisable, fair to, and in the best interests of the Company and the DoubleVerify stockholders, (ii) authorized and approved the execution and delivery of the Merger Agreement and the performance by the Company of its covenants and obligations contained in the Merger Agreement and the consummation by the Company of the Transactions, including the Merger, and (iii) resolved to recommend that DoubleVerify stockholders approve the adoption of the Merger Agreement and the Transactions, including the Merger, in each case, on the terms and subject to the conditions of the Merger Agreement. At the Special Meeting, DoubleVerify will ask you and the other Company stockholders to adopt the Merger Agreement (the “Merger Agreement Proposal”).

Additionally, you will be asked to consider and vote at the Special Meeting on (i) a proposal to approve, by a non-binding advisory vote, the compensation that may be paid or become payable to DoubleVerify’s named executive officers that is based on or otherwise relates to the Merger (the “Compensation Proposal”) and (ii) a proposal to adjourn the Special Meeting to a later date or time, if necessary or appropriate, including to ensure that any necessary supplement or amendment to the proxy statement accompanying this notice is

TABLE OF CONTENTS

provided to Company stockholders a reasonable amount of time in advance of the Special Meeting, or to solicit additional proxies in favor of the Merger Agreement Proposal if there are insufficient votes at the time of the Special Meeting to approve such proposal (the “Adjournment Proposal”).

The Company Board unanimously recommends, on behalf of DoubleVerify, that you vote (i) “FOR” the Merger Agreement Proposal, (ii) “FOR” the non-binding, advisory Compensation Proposal and (iii) “FOR” the Adjournment Proposal.

The enclosed proxy statement provides detailed information about the Special Meeting, the Merger Agreement and the Merger. A copy of the Merger Agreement is attached as Annex A to the proxy statement. We encourage you to carefully read the entire proxy statement and its annexes, including the Merger Agreement and the documents referred to or incorporated by reference in the proxy statement. You may also obtain additional information about the Company from other documents we have filed with the U.S. Securities and Exchange Commission (the “SEC”). In particular, you should read the “Risk Factors” section beginning on page 17 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, on page 29 of the Company’s Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2026 and other risk factors detailed from time to time in the Company’s reports filed with the SEC and incorporated by reference in the proxy statement, for risks relating to the Company’s business and for a discussion of the risks that you should consider in evaluating the proposed Merger and how it may affect you.

Your vote is very important, regardless of the number of shares of Company Common Stock that you own. We cannot complete the Merger unless the Merger Agreement Proposal is approved by the affirmative vote of the holders of at least a majority of the outstanding shares of Company Common Stock entitled to vote as of the close of business on [•], 2026, which is the record date for the Special Meeting. Whether or not you attend the Special Meeting online, it is important that your shares of Company Common Stock be represented and voted at the Special Meeting. Therefore, we urge you to promptly vote and submit your proxy by phone, via the Internet, or by signing, dating and returning the enclosed proxy card in the enclosed envelope, which requires no postage if mailed in the United States. Instructions on how to vote your shares of Company Common Stock are included in the enclosed proxy statement and proxy card. If you decide to attend the Special Meeting, you will be able to vote online at the Special Meeting even if you have previously submitted your proxy, as your proxy is revocable at your option. The failure to vote, assuming a quorum is present, will have the same effect as a vote “AGAINST” the Merger Agreement Proposal.

Under the General Corporation Law of the State of Delaware, stockholders and beneficial owners of shares of Company Common Stock who do not vote in favor of the adoption of the Merger Agreement have the right to seek an appraisal of the “fair value” of their shares of Company Common Stock as determined by the Delaware Court of Chancery, but only if they comply fully with the applicable requirements of Delaware law, which are summarized in the section captioned “The Merger — Appraisal Rights” in the accompanying proxy statement.

a proposal to adopt the Merger Agreement (the “Merger Agreement Proposal”);

•

a proposal to approve, on a non-binding, advisory basis, the compensation that may be paid or become payable to DoubleVerify’s named executive officers that is based on or otherwise related to the Merger Agreement and the Transactions (the “Compensation Proposal”); and

•

a proposal to adjourn the Special Meeting to a later date or time, if necessary or appropriate, including to ensure that any necessary supplement or amendment to the accompanying proxy statement is provided to DoubleVerify Stockholders a reasonable amount of time in advance of the Special Meeting or to solicit additional proxies to approve the Merger Agreement Proposal if there are insufficient votes to adopt such proposal at the time of the Special Meeting (the “Adjournment Proposal”).

We do not expect that any matters other than the proposals set forth above will be brought before the Special Meeting, and only matters specified in the notice of the meeting may be acted upon at the Special Meeting.

Shares Entitled to Vote; Quorum

You are entitled to receive notice of, and vote at, the Special Meeting if you owned shares of Company Common Stock at the close of business on the Record Date. Each holder of Company Common Stock will be entitled to one vote for each such share of Company Common Stock owned at the close of business on the Record Date on all matters properly coming before the Special Meeting.

TABLE OF CONTENTS

A quorum of DoubleVerify Stockholders is necessary to hold a valid Special Meeting. The holders of a majority of total voting power of the issued and outstanding shares of Company Common Stock entitled to vote at a meeting of stockholders, present virtually or represented by proxy, constitutes a quorum at the Special Meeting. On the Record Date, there were [•] shares of Company Common Stock outstanding and entitled to vote.

Your shares of Company Common Stock will be counted towards the quorum if you submit a valid proxy (or one is submitted on your behalf by your broker, dealer, commercial bank, trust company or other nominee) or if you vote in advance by telephone or online. Once a DoubleVerify Stockholder entitled to vote at the Special Meeting is present via the virtual meeting website or represented by proxy at the Special Meeting, such DoubleVerify Stockholder’s Company Common Stock will be counted for the purpose of determining a quorum at the Special Meeting and any adjournment of the Special Meeting, even if the Company Common Stock is not voted, including any Company Common Stock for which a DoubleVerify Stockholder directs to abstain from voting. If you are a “street name” holder of Company Common Stock and you provide your bank, broker, trust company or other nominee with voting instructions, then your Company Common Stock will be counted in determining the presence of a quorum. If you are a “street name” holder of Company Common Stock and you do not provide your bank, broker, trust or other nominee with voting instructions, then your Company Common Stock will not be counted in determining the presence of a quorum. For certain proposals, intermediaries may not use their discretion to vote in the absence of express voting instructions from you. If there is no quorum, a majority of the directors present at the Special Meeting may adjourn the Special Meeting to another place, if any, date and time.

Vote Required; Abstentions and Broker Non-Votes

The Merger Agreement Proposal requires, assuming a quorum is present, the affirmative vote of DoubleVerify Stockholders holding a majority of the outstanding shares of capital stock entitled to vote in accordance with the General Corporation Law of the State of Delaware (the “DGCL”) as of the close of business on the Record Date (the “Required Company Stockholder Approval”). Because the required vote for the Merger Agreement Proposal is based on the number of votes the DoubleVerify Stockholders are entitled to cast rather than on the number of votes actually cast, if you (1) are a record holder and fail to authorize a proxy or (2) are a beneficial holder and fail to instruct your broker on how to vote, such failure will have the same effect as votes cast “AGAINST” the Merger Agreement Proposal. As of [•], 2026, the Record Date for the Special Meeting, [•] shares of Company Common Stock constitute a majority of the issued and outstanding shares of Company Common Stock.

Approval of the Compensation Proposal, on a non-binding, advisory basis, requires, assuming a quorum is present, the affirmative vote of the holders of a majority in voting power of the Company Common Stock present in person or represented by proxy and entitled to vote on the matter at the Special Meeting. The approval of the Compensation Proposal is on a non-binding, advisory basis and is not a condition to the completion of the Merger.

Approval of the Adjournment Proposal to adjourn the Special Meeting, when a quorum is present, requires the affirmative vote of the DoubleVerify Stockholders holding a majority in voting power of the shares of Company Common Stock represented at the Special Meeting (present virtually or represented by proxy). When a quorum is not present, the Chairman of the Special Meeting or DoubleVerify Stockholders holding a majority in voting power of the outstanding shares of Company Common Stock represented at the Special Meeting (present virtually or represented by proxy) may adjourn the Special Meeting to another place, if any, date and time.

If a DoubleVerify Stockholder abstains from voting, that abstention will be counted for purposes of determining whether a quorum is present at the Special Meeting and will have the same effect as if the DoubleVerify Stockholder voted “AGAINST” the Merger Agreement Proposal. Because the required vote for the Compensation Proposal and the Adjournment Proposal is based on the number of shares of Company Common Stock present and entitled to vote rather than on the number of votes actually cast, abstentions will be counted for purposes of determining whether a quorum is present at the Special Meeting and will have the same effect as votes cast “AGAINST” the Compensation Proposal or the Adjournment Proposal.

TABLE OF CONTENTS

If no instructions as to how to vote are given in a validly executed, duly returned, and not revoked proxy, the proxy will be voted “FOR” (i) the proposal to adopt the Merger Agreement; (ii) the non-binding, advisory Compensation Proposal; and (iii) Adjournment Proposal.

The Company does not expect any broker non-votes at the Special Meeting because we believe the stock exchange rules applicable to banks, brokers and other nominees do not provide brokers with discretionary authority to vote on the proposals to be presented at the Special Meeting. As a result, we do not expect brokers would be permitted to vote your shares of Company Common Stock at the Special Meeting without receiving instructions. We believe the failure to instruct your broker on how to vote your shares of Company Common Stock will therefore have the same effect as a vote “AGAINST” the Merger Agreement Proposal and, assuming a quorum is present, no effect on the vote for the Compensation Proposal or the Adjournment Proposal.

However, if a beneficial owner of Company Common Stock held in “street name” gives voting instructions to the bank, broker or other nominee with respect to at least one of the proposals, but gives no instruction as to one or more of the other proposals, then that Company Common Stock will be deemed present at the Special Meeting for purposes of establishing a quorum at the Special Meeting, will be voted as instructed with respect to any proposal as to which instructions were given and will not be voted with respect to any other proposal.

Stock Ownership and Interests of Certain Persons

As of the close of business on the Record Date, our directors and executive officers beneficially owned and were entitled to vote, in the aggregate, [•] shares of Company Common Stock, representing approximately [•] % of the shares of Company Common Stock outstanding on the Record Date.

Our directors and executive officers have informed us that they currently intend to vote all of their respective shares of Company Common Stock (i) “FOR” the Merger Agreement Proposal, (ii) “FOR” the non-binding, advisory Compensation Proposal, and (iii) “FOR” the Adjournment Proposal.

See the section titled “The Special Meeting” beginning on page 27, for additional information on the Special Meeting.

Voting of Proxies (see page 28)

If you are a DoubleVerify Stockholder of record (that is, if your shares of Company Common Stock are registered in your name with Equiniti Trust Company, LLC (“Equiniti”), our transfer agent), there are four (4) ways to vote:

•

by visiting the Internet at the address on your proxy card;

•

by calling toll-free (within the U.S. or Canada) at the phone number on your proxy card;

•

by signing, dating and returning the enclosed proxy card in the accompanying prepaid reply envelope; or

•

by attending the Special Meeting virtually and voting at the meeting.

Please be aware that, although there is no charge for voting your shares of Company Common Stock, if you vote electronically over the Internet or by telephone, you may incur costs such as Internet access and telephone charges for which you will be responsible.

Even if you plan to attend the Special Meeting virtually, you are strongly encouraged to vote your shares of Company Common Stock by proxy. If you are a record holder or if you obtain a “legal proxy” to vote shares of Company Common Stock that you beneficially own, you may still vote your shares of Company Common Stock virtually at the Special Meeting even if you have previously voted by proxy. If you are present at the Special Meeting and vote virtually, your previous vote by proxy will be cancelled and not counted.

TABLE OF CONTENTS

dealer, broker, trust company or other nominee, electronically over the Internet or by telephone. To vote over the Internet or by telephone through your commercial bank, dealer, broker, trust company or other nominee, you should follow the instructions on the voting form provided by your commercial bank, dealer, broker, trust company or other nominee.

See the section titled “The Special Meeting — Voting of Proxies” beginning on page 28 for additional information.

Revocability of Proxies (see page 29)

If you are a DoubleVerify Stockholder of record entitled to vote at the Special Meeting, you can revoke or change your proxy at any time before the Special Meeting is held. If you are the record holder of your shares of Company Common Stock, you may revoke or change your proxy in any one of the following ways:

•

Attending the Special Meeting online and voting electronically during the meeting. However, your attendance online at the Special Meeting will not automatically revoke your proxy unless you properly vote electronically during the Special Meeting;

•

Specifically requesting that your prior proxy be revoked by delivering a written notice of revocation prior to the Special Meeting to the Corporate Secretary at DoubleVerify’s corporate headquarters at 462 Broadway, New York, NY 10013;

•

Properly casting a new vote via the Internet or by telephone at any time before the closure of the Internet or telephone voting facilities; or

•

Duly completing a later-dated proxy card relating to the same shares of Company Common Stock and delivering it to the Corporate Secretary before the taking of the vote at the Special Meeting.

At the time the Special Meeting occurs, the most current proxy card or telephone or Internet proxy is the one that is counted.

See the section titled “The Special Meeting — Revocability of Proxies” beginning on page 29 for additional information.

Adjournments (see page 29)

Although it is not currently expected, the Special Meeting may be adjourned to any other time and to any other place (whether virtual or not) by the DoubleVerify Stockholders present or represented at the Special Meeting, although less than a quorum, including for the purpose of ensuring that any necessary supplement or amendment to the accompanying proxy statement is provided to DoubleVerify Stockholders a reasonable amount of time in advance of the Special Meeting or soliciting additional proxies if there are insufficient votes at the time of the Special Meeting to approve the Merger Agreement Proposal or if a quorum is not present at the Special Meeting. Other than an announcement to be made at the Special Meeting of the time, date and place (whether virtual or not) of an adjourned meeting, an adjournment generally may be made without notice. Any adjournment of the Special Meeting for the purpose of soliciting additional proxies will allow the DoubleVerify Stockholders who have already sent in their proxies to revoke them at any time prior to their use at the Special Meeting as adjourned.

See the section titled “The Special Meeting — Adjournments” beginning on page 29 for additional information.

The Company Board’s Recommendation (see page 29)

After careful consideration, DoubleVerify’s Board of Directors (the “Company Board”), acting on the unanimous recommendation of the special committee of the Company Board formed to, among other things, review, evaluate and negotiate the Merger Agreement and the Transactions (the “Special Committee”), has (i) determined that the Merger Agreement, the Merger and the other Transactions are advisable, fair to, and in the best interests of the Company and the DoubleVerify Stockholders, (ii) authorized and approved the execution and delivery of the Merger Agreement and the performance by the Company of its covenants and obligations contained in the Merger Agreement and the consummation by the Company of the Transactions,

TABLE OF CONTENTS

including the Merger, and (iii) resolved to recommend that DoubleVerify Stockholders approve the adoption of the Merger Agreement and the Transactions, including the Merger, in each case, on the terms and subject to the conditions of the Merger Agreement.

Accordingly, the Company Board recommends, on behalf of DoubleVerify, that you vote as follows: (i) “FOR” the Merger Agreement Proposal; (ii) “FOR” the non-binding, advisory Compensation Proposal; and (iii) “FOR” the Adjournment Proposal.

Neptune BidCo US Inc.

Parent was formed in Delaware on March 17, 2022, for the purpose of effecting the acquisition of Nielsen Holdings plc and related financing transactions. Since the completion of the acquisition of Nielsen Holdings plc, Parent (together with its subsidiaries, “Nielsen”) has served as the parent company of Nielsen. For more than 100 years, Nielsen has been a global leader in audience measurement, data, and analytics.

TABLE OF CONTENTS

Effect of the Merger

On the terms and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, and in accordance with the DGCL, Merger Sub will merge with and into DoubleVerify, with DoubleVerify surviving the merger and continuing as the surviving corporation (the “Surviving Corporation”) and a wholly owned subsidiary of Parent. As a result of the Merger, Company Common Stock will no longer be publicly traded, and will be delisted from the NYSE. In addition, Company Common Stock will be deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and DoubleVerify will no longer file periodic reports with the Securities and Exchange Commission (the “SEC”) with respect to Company Common Stock. If the Merger is completed, as of immediately following the Effective Time (as defined below), you will not own any shares of the capital stock of the Surviving Corporation.

The Merger will become effective upon the filing of a duly executed certificate of merger with the Secretary of State of the State of Delaware or at such later date or time as may be specified in the certificate of merger and agreed to in writing by the parties to the Merger Agreement in accordance with the DGCL (such time, the “Effective Time”).

For more information about the effect of the Merger, see the section titled “The Merger — Effect of the Merger” beginning on page 31.

Effect on DoubleVerify if the Merger is Not Completed

If the Merger Agreement is not adopted by the DoubleVerify Stockholders, or if the Merger is not completed for any other reason:

•

the DoubleVerify Stockholders will continue to hold their shares of Company Common Stock and will not be entitled to, nor will they receive, any payment for their respective shares of Company Common Stock pursuant to the Merger Agreement;

•

(A) DoubleVerify will remain an independent public company, (B) Company Common Stock will continue to be listed and traded on the NYSE and registered under the Exchange Act, and (C) DoubleVerify will continue to file periodic reports with the SEC;

•

DoubleVerify anticipates that (A) management will operate the business in a manner similar to that in which it is being operated today and (B) DoubleVerify Stockholders will be subject to similar types of risks and uncertainties as those to which they are currently subject, including, but not limited to, risks and uncertainties with respect to DoubleVerify’s business, prospects and results of operations, as such may be affected by, among other things, the industry in which DoubleVerify operates and economic conditions;

•

the price of Company Common Stock may decline significantly, and if that were to occur, it is uncertain when, if ever, the price of Company Common Stock would return to the price at which it trades as of the date of this proxy statement;

•

the Company Board will continue to evaluate and review DoubleVerify’s business operations, strategic direction and capitalization, among other things, and will make such changes as are deemed appropriate (irrespective of these efforts, it is possible that no other transaction acceptable to the Company Board would be offered and that DoubleVerify’s business, prospects and results of operations would be adversely impacted); and

•

under certain specified circumstances, DoubleVerify may be required to pay Parent a termination fee in the amount of $60,000,000 (the “Company Termination Fee”). For more information, please see the sections of this proxy statement titled “Proposal 1: The Merger Agreement Proposal — Termination of the Merger Agreement” and “Proposal 1: The Merger Agreement Proposal — Termination Fee and Expenses.”

TABLE OF CONTENTS

Merger Consideration

Company Common Stock

At the Effective Time, subject to the terms and conditions of the Merger Agreement, by virtue of the Merger, the following will occur:

•

each share of Company Common Stock issued and outstanding as of immediately prior to the Effective Time will be automatically converted into and shall thereafter represent the right to receive $13.60 in cash, without interest and subject to deduction for any required withholding tax (the “Merger Consideration”), except that no Merger Consideration will be paid with respect to any shares of Company Common Stock (A) owned directly or indirectly by Parent, Merger Sub or any wholly owned subsidiary of Parent or Merger Sub, (B) any shares held by the Company or any wholly owned subsidiary of the Company (including those held in the Company’s treasury) or (C) any shares of Company Common Stock held by DoubleVerify Stockholders that have properly and validly exercised, and not withdrawn, their demand for rights to appraisal in accordance with Section 262 of the DGCL (such shares, the “Dissenting Shares”);

•

each share of common stock of Merger Sub, par value $0.0001 per share, issued and outstanding immediately prior to the Effective Time will automatically be converted into one validly issued, fully paid and nonassessable share of common stock, par value $0.0001 per share, of the Surviving Corporation; and

•

all shares of Company Common Stock will no longer be outstanding and will automatically be canceled and cease to exist, and thereafter only represent the right to receive the Merger Consideration, without interest and subject to deduction for any required withholding tax (except for holders of Dissenting Shares as described in this section and in the section titled “The Merger — Appraisal Rights”).

After the Merger is completed, you will have the right to receive the Merger Consideration in respect of each share of Company Common Stock that you own (less any required withholding tax), but you will no longer have any rights as a DoubleVerify Stockholder (except that DoubleVerify Stockholders who properly exercise, and do not withdraw, their appraisal rights will have a right to receive payment of the “fair value” of their shares of Company Common Stock as determined pursuant to an appraisal proceeding, as contemplated by Section 262 of the DGCL). For more information, please see the section of this proxy statement titled “The Merger — Appraisal Rights.”

For more information about the Merger Consideration, see the section titled “The Merger — Merger Consideration,” beginning on page 32.

Treatment of Company Equity Awards

The Merger Agreement also provides for the following treatment of outstanding DoubleVerify equity awards, each of which will occur at the Effective Time, by virtue of the Merger:

•

Each vested, in-the-money stock option (each, a “Company Stock Option”), including each Company Stock Option that vests in connection with the closing of the Merger (the “Closing” and the date on which such Closing actually occurs, the “Closing Date”), will be cashed out for its aggregate spread value (based on the excess of the Merger Consideration over the per-Share exercise price and the number of shares of Company Common Stock underlying such Company Stock Option). Each unvested, in-the-money Company Stock Option will be converted to a cash award (a “Cash Replacement Award”) equal to its aggregate spread value which will vest and be paid out on the same vesting terms that applied to the corresponding Company Stock Option. All underwater Company Stock Options (whether vested or unvested) will be canceled for no consideration.

•

Each vested restricted stock unit (each, a “Company RSU”), including each Company RSU that vests in connection with the Closing, will be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such vested Company RSU. Each unvested Company RSU will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of unvested shares of Company Common

TABLE OF CONTENTS

Stock subject to such Company RSU, which will vest and be paid out on the same vesting terms that applied to the corresponding Company RSU.

•

Each performance share unit (each, a “Company PSU”) as to which the applicable performance-based vesting conditions have been satisfied and that remain subject solely to service-based vesting conditions (each, an “Earned Company PSU”), will, to the extent vested as of immediately prior to the Effective Time, be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such vested Earned Company PSU. Each Earned Company PSU that does not vest in connection with the Closing will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such unvested Earned Company PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Earned Company PSU. Each Company PSU that is not an Earned Company PSU will be converted into a restricted stock unit award (each, a “Converted PSU”) with respect to the number of shares of Company Common Stock determined by the Compensation Committee of the Company Board (the “Compensation Committee”) based on performance through the Effective Time, in accordance with the underlying award agreement, subject to Parent’s review and reasonable comment. Each Converted PSU will be converted into the right to receive a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such Converted PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Converted PSU.

•

All Cash Replacement Awards will accelerate upon a severance-eligible employment termination within twelve months following the Effective Time, or the holder’s death.

For more information about the treatment of Company equity awards see the section titled “The Merger — Merger Consideration” beginning on page 32.

Recommendation of the Company Board and Reasons for the Merger (see page 52)

After careful consideration, the Company Board, acting on the unanimous recommendation of the Special Committee, has (i) determined that the Merger Agreement, the Merger and the other Transactions are advisable, fair to, and in the best interests of the Company and the DoubleVerify Stockholders, (ii) authorized and approved the execution and delivery of the Merger Agreement and the performance by the Company of its covenants and obligations contained in the Merger Agreement and the consummation by the Company of the Transactions, including the Merger, and (iii) resolved to recommend that DoubleVerify Stockholders approve the adoption of the Merger Agreement and the Transactions, including the Merger, in each case, on the terms and subject to the conditions of the Merger Agreement.

Accordingly, the Company Board unanimously recommends, on behalf of DoubleVerify, that you vote (i) “FOR” the Merger Agreement Proposal; (ii) “FOR” the non-binding, advisory Compensation Proposal; and (iii) “FOR” the Adjournment Proposal.

Opinion of PJT Partners (see page 59 and Annex B)

PJT Partners LP (“PJT Partners”) was retained by the Special Committee to act as its financial advisor in connection with the Merger and, upon the Special Committee’s request, to render its fairness opinion to the Special Committee and the Company Board in connection therewith. The Special Committee selected PJT Partners to act as its financial advisor based on PJT Partners’ qualifications, expertise and reputation, its knowledge of the Company’s industry and its knowledge and understanding of the business and affairs of the Company. At a meeting of the Special Committee on August 6, 2026, PJT Partners rendered its oral opinion, subsequently confirmed in its written opinion dated August 6, 2026, to the Special Committee and the Company Board that, as of the date thereof and based upon and subject to, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken by PJT Partners in connection with the opinion (which are stated in its written opinion), the

Merger Consideration to be received by the holders of shares of Company Common Stock (other than the shares of Company Common Stock held in the treasury of DoubleVerify or owned, directly or indirectly, by Parent, Merger Sub or a wholly owned subsidiary of DoubleVerify (collectively, the “Excluded Shares”) and any Dissenting Shares) in the Merger was fair to such holders from a financial point of view.

The full text of PJT Partners’ written opinion delivered to the Special Committee and the Company Board, dated August 6, 2026, is attached as Annex B and incorporated into this proxy statement by reference in its entirety. PJT Partners’ written opinion has been provided by PJT Partners at the request of the Special Committee and is subject to, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken by PJT Partners in connection with the opinion (which are stated therein). You are encouraged to read the opinion carefully in its entirety. PJT Partners provided its opinion to the Special Committee and the Company Board, in their respective capacities as such, in connection with and for purposes of their evaluation of the Merger only and PJT Partners’ opinion does not constitute a recommendation as to any action the Special Committee or the Company Board should take with respect to the Merger or how any holder of Company Common Stock should vote or act with respect to the Merger or any other matter. The summary of the PJT Partners opinion contained in this proxy statement is qualified in its entirety by reference to the full text of PJT Partners’ written opinion.

For a summary of PJT Partners’ opinion and the methodology that PJT Partners used to render its opinion, see the section titled “Opinion of PJT Partners” beginning on page 59.

Voting and Support Agreement (see page 122)

Concurrently with the execution of the Merger Agreement, each of Providence VII U.S. Holdings L.P. and Providence Butternut Co-Investment L.P. (collectively, the “Supporting Stockholders”) entered into a Voting and Support Agreement with Parent (the “Voting Agreement”), pursuant to which the Supporting Stockholders have agreed, among other things and subject to the terms and conditions of the Voting Agreement, to vote the shares of Company Common Stock owned by the Supporting Stockholders (A) in favor of (i) the Merger and the adoption of the Merger Agreement and each of the other Transactions, (ii) any other actions presented at any meeting of the DoubleVerify Stockholders that are necessary to consummate the Transactions, and (iii) any proposal to adjourn or postpone such meeting to a later date if there are not sufficient votes for the adoption of the Merger Agreement on the date on which such meeting is held, and (B) against any proposal, action or agreement that would reasonably be expected to impede, interfere with, delay, postpone or adversely affect the Merger or Transactions. The Supporting Stockholders own approximately [11.8]% of the outstanding shares of Company Common Stock as of the close of business on the Record Date. For more information, please see the section of this proxy statement titled “Voting Agreement” beginning on page 122.

Interests of DoubleVerify’s Directors and Executive Officers in the Merger (see page 70)

The Company’s executive officers as of the date hereof and for purposes of this proxy statement are Mark Zagorski (Chief Executive Officer), Nicola Allais (Chief Financial Officer), Steven Mougis (Global Chief Commercial Officer), Andrew Grimmig (Chief Legal Officer) and Julie Eddleman (Former Executive Vice President and Global Commercial Officer). The Company’s non-employee directors as of the date hereof and for purposes of this proxy statement are Laura B. Desmond, Lucy Stamell Dobrin, Sundeep Jain, Robert Davis Noell, Rosario Perez, Jennifer Storms, Gary Swidler, Kelli Turner and Scott Wagner.

When considering the foregoing recommendation of the Company Board that the DoubleVerify Stockholders should vote to approve the Merger Agreement Proposal, the DoubleVerify Stockholders should be aware that DoubleVerify’s directors and executive officers may have certain interests in the Merger that may be different from, or in addition to, the interests of the DoubleVerify Stockholders more generally, including those interests listed below and in the section titled “Interests of DoubleVerify’s Directors and Executive Officers in the Merger,” beginning on page 70. The Company Board was aware of and considered these interests, among other matters, when (1) evaluating and negotiating the Merger Agreement, (2) approving the Merger Agreement and the Merger, and (3) recommending that the Merger Agreement Proposal be approved by the DoubleVerify Stockholders. These interests include the following:

TABLE OF CONTENTS

•

payment in respect of in-the-money vested Company Stock Options, vested Company RSUs, and vested Company PSUs and potential accelerated vesting and payment in respect of Cash Replacement Awards;

•

potential participation in Parent’s equity-based incentive plan or similar arrangements of the Surviving Corporation;

•

potential transaction-related bonuses payable in connection with the Merger;

•

potential severance benefits in the event of a qualifying termination of employment in connection with the Merger; and

•

continued indemnification and directors’ and officers’ liability insurance to be provided by the Surviving Corporation.

If the Merger Agreement Proposal is approved, the shares of Company Common Stock held by the Company Board and executive officers will be treated in the same manner as outstanding shares of Company Common Stock held by all other DoubleVerify Stockholders. For more information, please see the section of this proxy statement titled “Interests of DoubleVerify’s Directors and Executive Officers in the Merger.”

Financing of the Merger (see page 76)

The Merger is not conditioned upon receipt of financing by Parent, Merger Sub, or any of their respective Affiliates. We presently anticipate that the total funds needed to complete the Merger and the related Transactions will be approximately $2,332,000,000, excluding estimated transaction fees and expenses. Parent expects these amounts to be funded through a combination of committed debt financing, equity commitments, and cash available on Parent’s and DoubleVerify’s balance sheets.

In connection with the financing of the Merger, Elliott Associates, L.P. and Elliott International, L.P. (collectively, the “Equity Investors”) have entered into an equity commitment letter in favor of Parent, dated as of August 6, 2026 (the “Equity Commitment Letter”), pursuant to which the Equity Investors have severally committed, subject to the terms and conditions contained therein, to provide an aggregate amount in immediately available funds equal to $200,000,000 to Parent and Merger Sub, for the purpose of providing Parent and Merger Sub with sufficient cash, when taken together with cash available on DoubleVerify’s balance sheet and the proceeds of the Debt Financing (as defined below), to consummate the Merger, make certain cash payments required under the Merger Agreement on the Closing Date and pay all related fees and expenses (the “Equity Financing”).

The Equity Financing, together with the Debt Financing (as defined below), is in an amount sufficient to pay the Merger Consideration to DoubleVerify Stockholders in the Merger (and related Company fees and expenses). Parent has delivered to the Company a debt commitment letter (the “Debt Commitment Letter” and, together with the Equity Commitment Letter, the “Commitment Letters”), dated as of August 6, 2026, by and among Parent, Bank of America, N.A., BofA Securities, Inc., Barclays Bank PLC and Citigroup Global Markets Inc. (collectively, the “Initial Lenders”, and together with any other financial institutions that become parties thereto, the “Debt Commitment Parties”), pursuant to which the Debt Commitment Parties have committed to provide debt financing consisting of a $800,000,000 incremental term loan facility, and to the extent Parent is unable to place debt securities in an aggregate principal amount of $1,000,000,000, an up to $1,000,000,000 senior secured bridge facility (collectively, the “Debt Financing,” and with the Equity Financing, the “Financing”). Under the terms of the Debt Commitment Letter, the senior secured bridge facility, if funded, will mature on the first anniversary of the Closing Date. Any bridge loans not previously repaid in full will, upon maturity, automatically convert into senior secured conversion term loans (the “Secured Conversion Term Loans”) maturing on the date that is seven (7) years after the Closing Date. Beginning five (5) business days prior to the date on which bridge loans are converted into Secured Conversion Term Loans, and at the option of the applicable lenders, the Secured Conversion Term Loans may be exchanged in whole or in part for senior secured exchange notes (the “Secured Exchange Notes”) having an equal principal amount and maturing on the date that is seven (7) years after the Closing Date. No Secured Exchange Notes may be issued unless requests to exchange total at least $500 million in aggregate principal amount and at least $500 million of Secured Exchange Notes are outstanding immediately following the exchange. The Secured Exchange Notes would bear interest payable semi-annually in arrears and would be

secured on a pari passu basis with the incremental term loan facility. The obligations of the Debt Commitment Parties to provide Debt Financing under the Debt Commitment Letter are subject to a number of customary conditions. For more information, please see the section of this proxy statement titled “The Merger — Financing of the Merger — Debt Commitment Letter.”

The Company and each of the Equity Investors have also entered into a limited guarantee in favor of DoubleVerify, dated as of August 6, 2026 (the “Limited Guarantee”), pursuant to which each Equity Investor has agreed to guarantee (up to an agreed upon cap) the due and punctual payment of and discharge of its pro rata percentage of the payment obligations and liabilities of Parent and Merger Sub, if, as and when due, of (a) the Parent Termination Fee (as defined below) to the extent that such amount is required to be paid by Parent under the Merger Agreement, (b) the recovery costs payable to the Company in enforcing the payment of the Parent Termination Fee, if applicable, and (c) the reimbursement and indemnification obligations with respect to any reasonable and documented out-of-pocket third-party costs and expenses incurred by DoubleVerify and its subsidiaries in connection with the arrangement of the Debt Financing, and in the case of clause (a) and clause (b), solely in the event of certain circumstances giving rise to a valid termination of the Merger Agreement by (i) DoubleVerify in accordance therewith or (ii) Parent under certain circumstances therein.

For more information, see the section titled “The Merger — Financing of the Merger” beginning on page 76.

Appraisal Rights (see page 78)

If the Merger is consummated, DoubleVerify Stockholders of record and beneficial owners of shares of Company Common Stock who continuously hold such shares of Company Common Stock through the Effective Time, who do not vote their shares in favor of the adoption of the Merger Agreement, who properly demand appraisal of such shares in accordance with Section 262 of the DGCL, and who otherwise comply with the statutory requirements of Section 262 of the DGCL will be entitled to seek appraisal by the Court of Chancery of the State of Delaware (the “Delaware Court of Chancery”) of the “fair value” of their shares of Company Common Stock. The amount determined to be fair value by the court will be determined as of the Effective Time and could be more than, the same as or less than the Merger Consideration. Voting “AGAINST” or failing to vote “FOR” the adoption of the Merger Agreement by itself does not constitute a demand for appraisal within the meaning of Section 262 of the DGCL.

This section is intended as a brief summary of the material provisions of Delaware law pertaining to appraisal rights. The following discussion, however, is not a complete summary of the law pertaining to appraisal rights under the DGCL and is qualified in its entirety by the full text of Section 262 of the DGCL that is accessible at the following publicly available website: https://delcode.delaware.gov/title8/c001/sc09/index.html#262 and incorporated by reference herein. Due to the complexity of the appraisal process, DoubleVerify Stockholders and beneficial owners of shares of Company Common Stock who wish to seek appraisal of their shares or who wish to preserve their rights to do so should review the section of this proxy statement titled “The Merger — Appraisal Rights” and the applicable provisions of Section 262 of the DGCL carefully and are encouraged to seek the advice of legal counsel and financial advisors with respect to the exercise of appraisal rights since failure to timely and fully comply with the procedures set forth therein will result in the loss of such rights.

Generally, to exercise appraisal rights, DoubleVerify Stockholders of record and beneficial owners of shares of Company Common Stock must (1) properly demand appraisal of such holder’s or owner’s shares of Company Common Stock, (2) not vote in favor of the adoption of the Merger Agreement (whether by voting against the Merger Agreement Proposal, abstaining or otherwise not voting with respect to the adoption of the Merger Agreement), (3) continuously hold (in the case of a holder of record) or own (in the case of a beneficial owner) such shares of Company Common Stock through the effective date of the Merger, (4) not withdraw their demands or otherwise lose their rights to appraisal, and (5) otherwise comply with the statutory requirements and satisfy certain ownership thresholds set forth in Section 262 of the DGCL, in which case, such DoubleVerify Stockholder may be entitled to have their shares of Company Common Stock appraised by the Delaware Court of Chancery and to receive payment in cash for the “fair value” of their shares of Company Common Stock, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with (unless the Delaware Court of Chancery in its discretion determines otherwise

TABLE OF CONTENTS

for good cause shown) interest on the amount determined by the Delaware Court of Chancery to be fair value from the Effective Time through the date of payment of the judgment.

Failure to follow exactly the procedures specified under Section 262 of the DGCL may result in the loss of appraisal rights. In addition, the Delaware Court of Chancery will dismiss appraisal proceedings in respect of DoubleVerify unless certain stock ownership conditions are satisfied by the DoubleVerify Stockholders and beneficial owners of shares of Company Common Stock seeking appraisal. The DGCL requirements for exercising appraisal rights are described in further detail in this proxy statement, which is qualified in its entirety by Section 262 of the DGCL, the relevant section of the DGCL regarding appraisal rights. If you hold your shares of Company Common Stock through a bank, broker or other nominee and you wish to exercise appraisal rights, you should consult with your bank, broker or other nominee to determine the appropriate procedures for the making of a demand for appraisal on your behalf by your bank, broker or other nominee. For more information, please see the section of this proxy statement titled “The Merger — Appraisal Rights.”

Certain Material U.S. Federal Income Tax Consequences of the Merger (see page 85)

A “U.S. Holder” (as defined in the section entitled “The Merger — Certain Material U.S. Federal Income Tax Consequences of the Merger”) will generally recognize gain or loss for U.S. federal income tax purposes on the exchange of such U.S. Holder’s shares of Company Common Stock for the Merger Consideration (including any amounts required to be withheld for tax purposes) pursuant to the Merger in an amount equal to the difference, if any, between the amount of Merger Consideration such U.S. Holder receives pursuant to the Merger (including any amounts required to be withheld for tax purposes) and such U.S. Holder’s adjusted tax basis in such surrendered shares.

A “Non-U.S. Holder” (as defined in the section entitled “The Merger — Certain Material U.S. Federal Income Tax Consequences of the Merger”) will generally not be subject to U.S. federal income tax with respect to the exchange of such Non-U.S. Holder’s shares of Company Common Stock for Merger Consideration in the Merger unless such Non-U.S. Holder has certain connections to the United States or such shares are treated as a United States real property interest in such Non-U.S. Holder’s hands, which we do not believe they are.

For more information, please see the section of this proxy statement titled “The Merger — Certain Material U.S. Federal Income Tax Consequences of the Merger”.

Each DoubleVerify Stockholder should consult its tax advisor in light of its particular circumstances and any specific tax consequences relating to the Merger, including U.S. federal, state, local and non-U.S. income and other tax consequences.

Regulatory Approvals Required for the Merger (see page 88)

Completion of the Merger is subject to clearances under the Hart — Scott — Rodino Antitrust Improvements Act of 1976 (the “HSR Act”) and filings and approvals under the Antitrust Laws (as defined in the section titled “The Merger — Regulatory Approvals Required for the Merger”) of other foreign jurisdictions, including the Australian Competition and Consumer Act 2010 (Cth), the Cyprus Control of Concentrations Between Undertakings Law of 2014 (Law 83(I)/2014), the German Act Against Restraints of Competition (Gesetz gegen Wettbewerbsbeschränkungen) and the Moroccan Law No. 104-12 on Freedom of Prices and Competition (Loi n° 104-12 sur la liberté des prix et de la concurrence).

DoubleVerify, Parent and Merger Sub have agreed to use their reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, and cooperate with each other in order to do, all things necessary, proper or advisable under Antitrust Laws to consummate the Transactions at the earliest practicable date, subject to certain limitations, further described in the section titled “The Merger — Regulatory Approvals Required for the Merger.”

Parent and DoubleVerify filed the notification required under the HSR Act with the Premerger Notification Office of the Federal Trade Commission (the “FTC”) and the Antitrust Division of the United States Department of Justice (the “DOJ”) on August 20, 2026. A transaction notifiable under the HSR Act may not be completed until the expiration or termination of a 30-day waiting period following the parties’

TABLE OF CONTENTS

filings of their HSR Act notification and report forms. If the FTC or the DOJ issues a request for additional information and documentary materials (a “Second Request”) prior to the expiration of the initial waiting period, the parties must observe a second 30-day waiting period, which would begin to run only after the parties have substantially complied with the Second Request, unless the waiting period is terminated earlier or the parties otherwise agree to extend the waiting period.

On September 3, 2026, notification and report forms were filed by the parties with certain foreign merger control authorities under the Antitrust Laws and competition laws of Australia, Cyprus, Germany and Morocco.

THE MERGER AGREEMENT PROPOSAL (see page 90)

A summary of the material provisions of the Merger Agreement, which is attached as Annex A to this proxy statement and which is incorporated by reference in this proxy statement, is described in the section of this proxy statement titled “Proposal 1: The Merger Agreement Proposal” beginning on page 90. Among other things, the Merger Agreement includes the below terms and obligations.

Non-Solicitation (see page 99)

No Solicitation of Other Offers

During the period beginning with the date of the Merger Agreement and continuing until the earlier of (x) the valid termination of the Merger Agreement or (y) the Effective Time, DoubleVerify has agreed not to, and has agreed to cause its subsidiaries and their respective officers, directors and employees not to, and has agreed to instruct and use commercially reasonable efforts to cause its and its subsidiaries’ other Representatives not to, directly or indirectly:

•

initiate, seek, solicit or knowingly facilitate or encourage any discussions, inquiries, proposals or offers that constitute, or would reasonably be expected to lead to, an Acquisition Proposal (as defined in the section titled “Proposal 1: The Merger Agreement Proposal — Acquisition Proposals”);

•

other than pursuant to the terms of the Merger Agreement, enter into, engage, continue or otherwise participate in any negotiations or discussions, provide or cause to be provided any non-public information or data relating to DoubleVerify or any of its subsidiaries, or afford access to the books or records of officers of DoubleVerify or any of its subsidiaries, in each case for the purpose of encouraging or knowingly facilitating the making, submission or announcement of any proposal or inquiry that constitutes, or would reasonably be expected to lead to, an Acquisition Proposal;

•

enter into any Alternative Acquisition Agreement (as defined in the section titled “Proposal 1: The Merger Agreement Proposal — Adverse Recommendation Changes and Alternative Acquisition Agreements”) or enter into any agreement requiring DoubleVerify to abandon, terminate or fail to consummate the Transactions; or

•

endorse, approve or recommend any proposal that constitutes, or would reasonably be expected to lead to, an Acquisition Proposal.

At any time after the date of the Merger Agreement, but prior to the receipt of the Required Company Stockholder Approval, if DoubleVerify receives an unsolicited bona fide written Acquisition Proposal that did not result from a breach (other than an immaterial breach) of the non-solicitation covenants in the Merger Agreement and the Company Board or any committee of the Company Board (including the Special Committee) determines in good faith, after consultation with its financial advisors and outside legal counsel, (1) that such Acquisition Proposal constitutes or would reasonably be expected to lead to a Superior Proposal (as defined in the section titled “Proposal 1: The Merger Agreement Proposal — Acquisition Proposals”), and (2) that the failure to take such action would be inconsistent with the Company Board’s fiduciary duties under applicable law, then DoubleVerify may (i) furnish information (including non-public information with respect to the Company and its subsidiaries), and afford access to the books or records or officers of the Company

TABLE OF CONTENTS

and its subsidiaries, to the person making such Acquisition Proposal, pursuant to a customary confidentiality agreement; (ii) engage or participate in discussions or negotiations with such person or its representatives regarding such Acquisition Proposal; and (iii) otherwise facilitate and encourage such Acquisition Proposal; provided that, prior to, or substantially concurrently with, the time such information is provided to such person or its representatives, DoubleVerify shall, subject to applicable law and any applicable “clean team” or similar arrangement, provide or make available to Parent any non-public information concerning the Company or any of its subsidiaries that is provided to the person making such Acquisition Proposal or its representatives which was not previously made available to Parent.

Additionally, if (A) the Company receives an unsolicited bona fide written Acquisition Proposal that did not result from a breach (other than an immaterial breach) of the non-solicitation covenants in the Merger Agreement, and (B) the Company Board or any committee of the Company Board (including the Special Committee) determines in good faith, after consultation with its financial advisors and outside legal counsel that (x) such Acquisition Proposal constitutes a Superior Proposal and (y) the failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties under applicable law, the Company Board may (i) make an Adverse Recommendation Change, or (ii) terminate the Merger Agreement to enter into an Alternative Acquisition Agreement with respect to such Superior Proposal, or authorize, resolve, agree or propose publicly to take any such action, if, in each case, all of the following conditions are met: (1) the Company provides Parent four (4) Business Days’ prior written notice of its intention to take such action, which notice will (a) state expressly that the Company has received a written Acquisition Proposal that constitutes a Superior Proposal, (b) include as exhibits thereto an unredacted copy of the Alternative Acquisition Agreement and any other contracts available to DoubleVerify to be entered into in connection with such Acquisition Proposal that DoubleVerify received, and (c) state expressly that, subject to any revisions to the terms and conditions of the Merger Agreement, the Company Board or any committee thereof has determined to make an Adverse Recommendation Change or to terminate the Merger Agreement in order to enter into the Alternative Acquisition Agreement, as applicable (provided that, if the applicable alternative acquiror amends any of the financial terms or any other material term or condition of the applicable Superior Proposal, the Company will be required to provide Parent with a new notice and an additional three (3) business day matching period from the time of Parent’s receipt of such new notice), (2) during the applicable notice period (including any extensions) and prior to making any Adverse Recommendation Change or terminating the Merger Agreement to enter into such Superior Proposal, the Company negotiates and engages, and causes its directors, officers and employees to, and instructs and uses commercially reasonable efforts to cause its other representatives to negotiate and engage, with Parent in good faith to propose any adjustments to the terms and conditions of the Merger Agreement such that the Acquisition Proposal ceases to be a Superior Proposal, and (3) at the end of the applicable notice period, the Company Board (or any committee thereof) again determines in good faith, after consultation with its outside legal counsel and financial advisors (and after taking into account any adjustments proposed in writing by Parent during the notice period), that the Acquisition Proposal continues to constitute a Superior Proposal and that the failure to make such Adverse Recommendation Change or to terminate the Merger Agreement would be inconsistent with its fiduciary duties under applicable law.

For more information, please see the section of this proxy statement titled “Proposal 1: The Merger Agreement Proposal — Acquisition Proposals.”

If DoubleVerify terminates the Merger Agreement for the purpose of accepting and entering into an agreement in respect of a Superior Proposal, DoubleVerify is required to pay the Company Termination Fee to Parent. For more information, please see the section of this proxy statement titled “Proposal 1: The Merger Agreement Proposal — Termination Fee and Expenses.”

What will I receive if the Merger is completed?

Upon completion of the Merger, you will be entitled to receive an amount in cash equal to $13.60, without interest thereon and subject to any required withholding tax, for each share of Company Common Stock that you own immediately prior to the Effective Time, unless you are entitled to, and have properly exercised and not withdrawn, failed to perfect or otherwise lost, appraisal rights under Section 262 of the DGCL. For example, if you own one hundred (100) shares of Company Common Stock, you would receive $1,360 in cash in exchange for your shares of Company Common Stock, without interest and subject to deduction for any required withholding tax. You will not receive any shares of the capital stock in the Surviving Corporation. For more information, please see the section of this proxy statement titled “Proposal 1: The Merger Agreement Proposal — Merger Consideration.”

How does the Merger Consideration compare to the market price of Company Common Stock prior to the announcement of entry into the Merger Agreement?

The Merger Consideration represents a 22%, 30%, and 30% premium to the price per share of Company Common Stock, based on the volume weighted average price for the 30, 60 and 90 trading day periods, respectively, ending on August 5, 2026, the last trading day prior to the announcement of the transaction. On [•], 2026, the last practicable day before the printing of this proxy statement, the closing price of Company Common Stock on the NYSE was $[•] per share.

What will I receive for my Company Stock Options, Company RSUs, and Company PSUs, as applicable, if the Merger is completed?

At the Effective Time, by virtue of the Merger:

•

Each vested, in-the-money Company Stock Option, including awards that vest in connection with the Closing, will be cashed out for its aggregate spread value (based on the excess of the Merger Consideration over the per-Share exercise price and the number of Shares underlying such Company Stock Option). Each unvested, in-the-money Company Stock Option will be converted to a Cash Replacement Award equal to its aggregate spread value which will vest and be paid out on the same vesting terms that applied to the corresponding Company Stock Option. All underwater Company Stock Options (whether vested or unvested) will be canceled for no consideration.

•

Each vested Company RSU, including each award that vests in connection with the Closing, will be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of

TABLE OF CONTENTS

shares of Company Common Stock subject to such vested Company RSU. Each unvested Company RSU will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of unvested shares of Company Common Stock subject to such Company RSU, which will vest and be paid out on the same vesting terms that applied to the corresponding Company RSU.

•

Each Company PSU as to which the applicable performance-based vesting conditions have been satisfied and that remain subject solely to service-based vesting conditions will, to the extent vested as of immediately prior to the Effective Time, be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such vested Earned Company PSU. Each Earned Company PSU that does not vest in connection with the Closing will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such unvested Earned Company PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Earned Company PSU. Each Company PSU that is not an Earned Company PSU will be converted into a Converted PSU with respect to the number of shares of Company Common Stock determined by the Compensation Committee based on performance through the Effective Time, in accordance with the underlying award agreement, subject to Parent’s review and reasonable comment. Each Converted PSU will be converted into the right to receive a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such Converted PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Converted PSU.

•

All Cash Replacement Awards will accelerate upon a severance-eligible employment termination within twelve months following the Effective Time, or the holder’s death.

•

For more information about the treatment of Company equity awards, please see the section of this proxy statement titled “The Merger — Merger Consideration” beginning on page 32.

What will happen to the DoubleVerify Holdings, Inc. Employee Stock Purchase Plan?

No new offerings will commence under the DoubleVerify Holdings, Inc. Employee Stock Purchase Plan (the “Company ESPP”), no new elections can be made to participate in the current offering under the Company ESPP, and no current participant may increase his or her rate of payroll contributions under the Company ESPP. The Company ESPP will terminate prior to the Effective Time and any ongoing offering will be shortened to the extent necessary to ensure that shares purchased under the offering are made at least five (5) business days prior to the Effective Time.

What are the material U.S. federal income tax consequences of the Merger?

The exchange of shares of Company Common Stock for the Merger Consideration pursuant to the Merger will be a taxable transaction for U.S. federal income tax purposes. Therefore, a U.S. Holder receiving cash pursuant to the Merger will generally recognize capital gain or loss for U.S. federal income tax purposes in an amount equal to the difference between (x) the amount of cash the U.S. Holder received (determined before deduction of any required withholding tax) and (y) the adjusted tax basis of the shares of Company Common Stock surrendered by such U.S. Holder.

A Non-U.S. Holder will generally not be subject to U.S. federal income tax on any gain resulting from the exchange of shares of Company Common Stock for the Merger Consideration pursuant to the Merger unless such holder has certain connections to the United States or such shares are treated as a United States real property interest in such Non-U.S. Holder’s hands, which we do not believe they are (as described under the section of this proxy statement titled “The Merger — Certain Material U.S. Federal Income Tax Consequences of the Merger”). The Merger could, however, be a taxable transaction to such Non-U.S. Holder under non-U.S. tax laws applicable to such Non-U.S. Holder.

For more information, please see the section of this proxy statement titled “The Merger — Certain Material U.S. Federal Income Tax Consequences of the Merger” and contact your personal tax advisors.

TABLE OF CONTENTS

When do you expect the Merger to be completed?

In order to complete the Merger, DoubleVerify is required to obtain the Required Company Stockholder Approval described in this proxy statement and the other closing conditions under the Merger Agreement must be satisfied or waived. Assuming timely satisfaction of necessary closing conditions, including obtaining the Required Company Stockholder Approval, DoubleVerify is currently targeting to consummate the Merger by the first quarter of 2027. Since the Merger is subject to a number of conditions, the exact timing of the Merger cannot be determined at this time and may occur before or after such time.

What happens if the Merger is not completed?

If the Merger Agreement is not adopted by DoubleVerify Stockholders or if the Merger is not completed for any other reason, DoubleVerify Stockholders will not receive any payment for their shares of Company Common Stock. Instead, DoubleVerify will remain an independent public company, shares of Company Common Stock will continue to be listed and traded on the NYSE and registered under the Exchange Act, and DoubleVerify will continue to file periodic reports with the SEC. Under specified circumstances, (i) DoubleVerify may be required to pay Parent the Company Termination Fee and (ii) Parent may be required to pay DoubleVerify the Parent Termination Fee upon the termination of the Merger Agreement, as described in the sections of this proxy statement titled “Proposal 1: The Merger Agreement Proposal — Termination of the Merger Agreement” and “Proposal 1: The Merger Agreement Proposal — Termination Fee and Expenses.”

What vote is required to adopt the Merger Agreement?

The affirmative vote of holders of a majority of the outstanding shares of Company Common Stock outstanding and entitled to vote as of the close of business on the Record Date is required to adopt the Merger Agreement.

What is a “broker non-vote”?

A “broker non-vote” results when the banks, brokers, or other nominees return a valid proxy voting upon a matter or matters for which the applicable rules provide discretionary authority but do not vote on a particular proposal because they do not have discretionary authority to vote on the matter and have not received specific voting instructions from the beneficial owner of such shares. The Company does not expect any broker non-votes at the Special Meeting because each of the proposals to be presented at the Special Meeting is expected to be considered “non-routine.” As a result, (i) no broker would be permitted to vote your shares of Company Common Stock at the Special Meeting without receiving instructions, and (ii) failure to instruct your broker on how to vote your shares of Company Common Stock will have the same effect as a vote “AGAINST” the Merger Agreement Proposal and, assuming a quorum is present, no effect on the vote for the Compensation Proposal or the Adjournment Proposal.

Why are DoubleVerify Stockholders being asked to cast a non-binding advisory vote to approve the Compensation Proposal?

The Exchange Act and applicable SEC rules thereunder require DoubleVerify to seek a non-binding, advisory vote with respect to certain payments that could become payable to its named executive officers in connection with the Merger.

What vote is required to approve the Compensation Proposal?

Assuming a quorum is present, the affirmative vote of the holders of a majority in voting power of the outstanding shares of Company Common Stock represented at the Special Meeting (present virtually or represented by proxy) is required for approval of the Compensation Proposal, on a non-binding, advisory basis. The approval of the Compensation Proposal is not a condition to the completion of the Merger.

TABLE OF CONTENTS

What will happen if DoubleVerify Stockholders do not approve the Compensation Proposal at the Special Meeting?

Approval of the Compensation Proposal is not a condition to the completion of the Merger. The vote with respect to the Compensation Proposal is an advisory vote and will not be binding on the Company. Therefore, if the other requisite stockholder approvals are obtained and the Merger is completed, the amounts payable under the Compensation Proposal will continue to be payable to DoubleVerify’s named executive officers in accordance with the terms and conditions of the applicable agreements.

What vote is required to approve the Adjournment Proposal?

If a quorum is present, the affirmative vote of the holders of a majority in voting power of the outstanding shares of Company Common Stock represented at the Special Meeting (present virtually or represented by proxy) is required for approval of the Adjournment Proposal. If a quorum is not present, the Chairman of the Special Meeting or the affirmative vote of the holders of a majority in voting power of the outstanding shares of Company Common Stock represented at the Special Meeting (present virtually or represented by proxy) may adjourn the Special Meeting to another place, if any, date and time.

If the adjournment is for more than thirty (30) days or a new record date is fixed for the adjourned meeting after the adjournment, a notice of the adjourned meeting, shall be given to each stockholder of record entitled to vote at the meeting. At the adjourned meeting, the Company may transact any business that might have been transacted at the original meeting.

What do I need to do now?

You should carefully read and consider this entire proxy statement and the annexes to this proxy statement, including the Merger Agreement, along with all of the documents that we refer to in this proxy statement, as they contain important information about, among other things, the Merger and how it affects you. Then sign, date and return, as promptly as possible, the enclosed proxy card in the accompanying reply envelope, or grant your proxy electronically over the Internet or by telephone (using the instructions provided in the enclosed proxy card), so that your shares of Company Common Stock can be voted at the Special Meeting, unless you wish to seek appraisal pursuant to Section 262 of the DGCL. If you hold your shares of Company Common Stock in “street name,” please refer to the voting instruction forms provided by your commercial bank, broker, dealer, trust company or other nominee to vote your shares of Company Common Stock.

May I exercise dissenters’ rights or rights of appraisal in connection with the Merger?

Yes. In order to exercise your appraisal rights, you must follow the requirements set forth in Section 262 of the DGCL. Under the DGCL, DoubleVerify Stockholders of record who continuously hold shares of Company Common Stock through the Effective Time and do not vote in favor of adopting the Merger Agreement, and beneficial owners of shares of Company Common Stock held either in voting trust or by a nominee on behalf of such person who beneficially own shares of Company Common Stock through the Effective Time that are not voted in favor of the adoption of the Merger Agreement will have the right to seek appraisal of the “fair value” of their shares of Company Common Stock as determined by the Delaware Court of Chancery if the Merger is completed. Appraisal rights will only be available to DoubleVerify Stockholders and beneficial owners of shares of Company Common Stock, as the case may be, who properly deliver a written demand for an appraisal to DoubleVerify prior to the vote on the Merger Agreement Proposal at the Special Meeting and do not withdraw their demands, and who otherwise comply with the procedures and requirements set forth in Section 262 of the DGCL, which are summarized in this proxy statement. The appraisal amount could be more than, the same as or less than the amount a DoubleVerify Stockholder will be entitled to receive under the terms of the Merger Agreement. Holders and beneficial owners of Company Common Stock who wish to seek appraisal of their shares are in any case encouraged to seek the advice of legal counsel with respect to the exercise of appraisal rights due to the complexity of the appraisal process. A copy of Section 262 of the DGCL is accessible at the following publicly available website:

TABLE OF CONTENTS

https://delcode.delaware.gov/title8/c001/sc09/index.html#262 and incorporated by reference herein. Failure to comply with the provisions of Section 262 of the DGCL in a timely and proper manner may result in the loss of appraisal rights. For additional information, please see the section of this proxy statement titled “The Merger — Appraisal Rights.”

What happens if I sell or otherwise transfer my shares of Company Common Stock after the Record Date but before the Special Meeting?

The Record Date for the Special Meeting is earlier than the date of the Special Meeting and the date the Merger is expected to be completed. If you sell or transfer your shares of Company Common Stock after the Record Date but before the Special Meeting, you will transfer the right to receive the Merger Consideration, if the Merger is completed, to the person to whom you sell or transfer your shares of Company Common Stock, but you will retain your right to vote those shares of Company Common Stock at the Special Meeting. You will also lose the ability to exercise appraisal rights in connection with the Merger with respect to the transferred shares of Company Common Stock.

What is the difference between holding shares as a DoubleVerify Stockholder of record and as a beneficial owner?

If your shares of Company Common Stock are registered directly in your name with our transfer agent, Equiniti, you are considered, with respect to those shares, to be the “stockholder of record.” In this case, this proxy statement and your proxy card have been sent directly to you by DoubleVerify.

If your shares of Company Common Stock are held through a commercial bank, broker, dealer, trust company or other nominee, you are considered the “beneficial owner” of shares of Company Common Stock held in “street name.” In that case, this proxy statement has been forwarded to you by your commercial bank, dealer, broker, trust company or other nominee who is considered, with respect to those shares of Company Common Stock, to be the stockholder of record. As the beneficial owner, you have the right to direct your commercial bank, dealer, broker, trust company or other nominee how to vote your shares of Company Common Stock by following their instructions for voting.

If my broker holds my shares in “street name,” will my broker vote my shares for me?

No. Your commercial bank, dealer, broker, trust company or other nominee will not be permitted to vote your shares of Company Common Stock on any proposal currently scheduled to be considered at the Special Meeting. As a result, the only way your shares of Company Common Stock may be voted at the Special Meeting is for you to instruct to your commercial bank, dealer, broker, trust company or other nominee on how to vote. You should follow the procedures provided by your commercial bank, dealer, broker, trust company or other nominee to vote your shares of Company Common Stock. Without instructions, your shares of Company Common Stock will not be voted on such proposals, which will have the same effect as if you voted “AGAINST” the Merger Agreement Proposal, and (ii) assuming a quorum is present, no effect on the vote for the Compensation Proposal or the Adjournment Proposal.

Q: How may I vote?

If your shares of Company Common Stock are registered in your name with our transfer agent, Equiniti, you are a “holder of record” of those shares of Company Common Stock. A holder of record may cause its shares of Company Common Stock to be voted in any of the following ways:

•

Internet: please log on to www.proxyvote.com and vote by 11:59 p.m., Eastern Time, on [•], 2026;

TABLE OF CONTENTS

These instructions appear on your Notice or proxy card. If you submit a proxy on the Internet or by telephone, please have your Notice or proxy card available for reference when you do so. If you submit a proxy via the Internet or by telephone, please do not mail in your proxy card.

If your shares of Company Common Stock are held in “street name” through a commercial bank, dealer, broker, trust company or other nominee, you may vote through your commercial bank, dealer broker, trust company or other nominee by completing and returning the voting form provided by your commercial bank, dealer, broker, trust company or other nominee, or, if such a service is provided by your commercial bank, dealer, broker, trust company or other nominee, electronically over the Internet or by telephone. To vote over the Internet or by telephone through your commercial bank, dealer, broker, trust company or other nominee, you should follow the instructions on the voting form provided by your commercial bank, dealer, broker, trust company or other nominee.

May I change my vote after I have mailed my signed and dated proxy card?

Stockholder of Record: Shares Registered in Your Name

Yes. You can revoke or change your proxy at any time before the Special Meeting. If you are the record holder of your shares of Company Common Stock, you may revoke or change your proxy in any one of the following ways:

•

Specifically request that your prior proxy be revoked by delivering a written notice of revocation prior to the Special Meeting to the Corporate Secretary at DoubleVerify’s Corporate headquarters at 462 Broadway, New York, NY 10013;

•

Properly casting a new vote via the Internet or by telephone at any time before the closure of the Internet or telephone voting facilities; or

•

Duly completing a later-dated proxy card relating to the same shares of Company Common Stock and delivering it to the Corporate Secretary before the taking of the vote at the Special Meeting.

At the time the Special Meeting occurs, your most current proxy card or telephone or Internet proxy is the one that is counted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If your shares of Company Common Stock are held by your broker, dealer, trust company or commercial bank as a nominee or agent, you should follow the instructions provided by your broker, dealer, trust company, or commercial bank.

How does the Company Board recommend that I vote?

DoubleVerify’s Board of Directors unanimously recommends, on behalf of DoubleVerify, that you vote: (1) “FOR” the Merger Agreement Proposal; (2) “FOR” the non-binding, advisory Compensation Proposal; and (3) “FOR” the Adjournment Proposal.

TABLE OF CONTENTS

For a discussion of the factors that the Company Board considered in determining to recommend that you vote to approve the proposal to adopt the Merger Agreement, please see the section captioned “The Merger — Recommendation of the Company Board and Reasons for the Merger.” In addition, when considering the recommendation of the Company Board, you should be aware that DoubleVerify’s directors and executive officers may have interests in the Merger that are different from, or in addition to, the interests of stockholders more generally. For a discussion of these interests, please see the section captioned “The Merger — Interests of DoubleVerify’s Directors and Executive Officers in the Merger.”

What factors did the Company Board consider in deciding to enter into the Merger Agreement and recommending the approval of the Merger Agreement Proposal, the Compensation Proposal and the Adjournment Proposal?

In reaching its decision to approve the Merger Agreement and the Transactions, and to recommend our stockholders approve the Merger Agreement Proposal, the Compensation Proposal and the Adjournment Proposal, among other things, the Company Board consulted with members of the Company’s management team, as well as our outside legal and financial advisors, considered the terms of the proposed Merger Agreement and the Transactions, as well as other alternatives, and considered the terms of the Compensation Proposal. For a more detailed description of these factors, see the section entitled “The Merger — Recommendation of the Company Board and Reasons for the Merger” of this proxy statement.

How do the Company Board and executive officers of DoubleVerify intend to vote?

Our directors and executive officers have informed us that they currently intend to vote all of their respective shares of Company Common Stock (i) “FOR” the adoption of the Merger Agreement, (ii) “FOR” the approval, on an advisory (non-binding) basis, of the Compensation Proposal and (iii) “FOR” the approval of the Adjournment Proposal.

Who is paying for the cost of this proxy solicitation?

The proxies being solicited hereby are being solicited by us, and the cost of soliciting proxies in the enclosed form will be borne by us. We have also retained Innisfree M&A Incorporated to aid in the solicitation. For these services, we will pay Innisfree M&A Incorporated a fee of approximately $30,000, plus a success fee of 50% of all fees paid, and reimburse it for certain out-of-pocket disbursements and expenses. Our officers and other employees may, without compensation other than their regular compensation, solicit proxies by further mailings, personal conversations, telephone, facsimile or other electronic means. We will, upon request, reimburse brokerage firms and others for their reasonable expenses in forwarding solicitation material to the beneficial owners of shares of Company Common Stock.

I share an address with another stockholder, and we received only one copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

The SEC rules permit brokers to participate in a practice known as “householding,” which means that only one copy of the proxy materials will be sent to multiple stockholders who share the same address unless we have received contrary instructions from one or more of the stockholders. Householding is designed to reduce printing and postage costs, and results in cost savings for us. DoubleVerify Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. If you receive a householding mailing this year and would like to have additional copies of this proxy statement mailed to you, or if you would like to opt out of this practice for future mailings, please contact your broker or submit your request to Investor Relations at DoubleVerify, 462 Broadway, New York, NY 10013, or by emailing your request to IR@doubleverify.com. Upon receipt of any such request, we agree to promptly deliver a copy of this proxy statement to you. In addition, if you are currently a stockholder sharing an address with another stockholder and wish to receive only one copy of future proxy materials for your household, please contact us using the contact information set forth above.

TABLE OF CONTENTS

If a DoubleVerify Stockholder gives a proxy, how are the shares voted?

The individuals named on the enclosed proxy card, or your proxies, will vote your shares of Company Common Stock in the way that you indicate. When completing the Internet or telephone process or the proxy card, you may specify whether your shares of Company Common Stock should be voted for or against or to abstain from voting on all, some or none of the specific items of business to come before the Special Meeting.

If you properly sign your proxy card but do not mark the boxes showing how your shares of Company Common Stock should be voted on a matter, the shares represented by your properly signed proxy will be voted (i) “FOR” the Merger Agreement Proposal; (ii) “FOR” the non-binding, advisory Compensation Proposal; and (iii) “FOR” the Adjournment Proposal.

What should I do if I receive more than one set of voting materials?

Please sign, date and return (or grant your proxy electronically over the Internet or by telephone using the instructions provided in the enclosed proxy card) each proxy card and voting instruction card that you receive.

You may receive more than one set of voting materials, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards. For example, if you hold your shares of Company Common Stock in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares of Company Common Stock. If you are a DoubleVerify Stockholder of record and your shares of Company Common Stock are registered in more than one name, you will receive more than one proxy card.

Where can I find the voting results of the Special Meeting?

If available, DoubleVerify may announce preliminary voting results at the conclusion of the Special Meeting. DoubleVerify intends to publish final voting results in a Current Report on Form 8-K to be filed with the SEC following the Special Meeting. All reports that DoubleVerify files with the SEC are publicly available when filed. For more information, please see the section of this proxy statement titled “Where You Can Find More Information.”

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This proxy statement contains not only historical information, but also forward-looking statements made pursuant to the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements represent DoubleVerify’s expectations or beliefs concerning future events, including the timing of the proposed Transactions and other information relating to the proposed Transactions (the “Transactions”). In some cases, you can identify these statements by forward-looking words such as “may,” “might,” “will,” “should,” “expects,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “likely” or “continue,” the negative of these terms and other comparable terminology. These statements are only predictions based on DoubleVerify’s expectations and projections about future events as of the date of this proxy statement and are subject to a number of risks, uncertainties and assumptions that may prove incorrect, any of which could cause actual results to differ materially from those expressed or implied by such statements. Important factors, risks and uncertainties that could cause actual results to differ materially from forward-looking statements include but are not limited to (i) the risk that the Merger may not be completed in a timely manner or at all, which may adversely affect DoubleVerify’s business and the price of the Company Common Stock; (ii) the timing to consummate the Merger, or the occurrence of any event, change, or other circumstances that could give rise to the termination of the Merger Agreement, including circumstances requiring a party to pay the other party a termination fee pursuant to the Merger Agreement; (iii) the failure to satisfy the conditions to the consummation of the Merger, and the other Transactions; (iv) the risk that a governmental or regulatory approval that may be required for the Merger is not obtained or is obtained subject to conditions that are not anticipated; (v) the effect of the pendency of the Merger on DoubleVerify’s business relationships, operating results and business generally and the response of competitors to the Transactions; (vi) certain restrictions or prohibitions under certain covenants in the Merger Agreement during the pendency of the Merger that may impact our ability to pursue certain business opportunities or strategic transactions; (vii) risks that the Merger disrupts current plans and operations; (viii) risks related to diverting management’s attention from our ongoing business operations; (ix) the outcome of any legal proceedings that may be instituted against the parties to the Merger Agreement or their respective directors, managers or officers, including the effects of any outcomes related thereto; (x) our ability to retain, hire and integrate skilled personnel, and maintain relationships with key business partners and customers, and others with whom we do business, in light of the proposed Merger; (xi) unexpected costs, charges or expenses resulting from the Merger; (xii) risks that the benefits of the Merger are not realized when and as expected; (xiii) those risks described under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2025, our Quarterly Report on Form 10-Q for the quarter ended June 30, 2026 and in other reports and filings with the SEC; and (xiv) risks related to Parent’s financing of the Transactions as a result of uncertainty or adverse developments in the debt or equity capital markets or otherwise. New risks emerge from time to time, and it is not possible for our management to predict all risks, nor can management assess the impact of all factors on DoubleVerify’s business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statement DoubleVerify makes. Investors are cautioned not to place undue reliance on any such forward-looking statements, which speak only as of the date they are made. Except as otherwise required by law, DoubleVerify undertakes no obligation to update any forward-looking statement, whether as a result of new information, future events or otherwise.

No assurance can be given that these are all of the factors that could cause actual results to vary materially from the forward-looking statements. DoubleVerify Stockholders are advised to consult any future disclosures that we make on related subjects as may be detailed in our other filings made from time to time with the SEC.

Date, Time and Place

We will hold the Special Meeting virtually on [•], 2026 at [•] a.m. Eastern Time at www.virtualshareholdermeeting.com/DV2026SM and, if applicable, at any adjournment or postponement thereof.

Purpose of the Special Meeting

At the Special Meeting, we will ask DoubleVerify Stockholders to vote on proposals to (i) approve the Merger Agreement Proposal; (ii) approve, on a non-binding advisory basis, the Compensation Proposal; and (iii) approve the Adjournment Proposal.

DoubleVerify Stockholders must approve the Merger Agreement Proposal in order for the Merger to be consummated. If the DoubleVerify Stockholders fail to approve the Merger Agreement Proposal, the Merger will not be consummated. A copy of the Merger Agreement is attached as Annex A to this proxy statement, which we urge you to read carefully in its entirety.

Record Date; Shares Entitled to Vote; Quorum

Only DoubleVerify Stockholders of record as of the close of business on the Record Date are entitled to notice of the Special Meeting, and to vote at the Special Meeting. A list of DoubleVerify Stockholders entitled to vote at the Special Meeting shall be open to examination of any stockholder at least ten (10) days prior to and during the meeting for any purpose germane to the meeting as required by the DGCL or other applicable law. The list of holders of shares of Company Common Stock entitled to notice of the Special Meeting will also be available for inspection by DoubleVerify Stockholders during the Special Meeting via the virtual meeting website at www.virtualshareholdermeeting.com/DV2026SM.

The holders of a majority of total voting power of the issued and outstanding shares of Company Common Stock entitled to vote at a meeting of stockholders, present virtually or represented by proxy, constitutes a quorum at the Special Meeting. As of the close of business on the Record Date, there were [•] shares of Company Common Stock outstanding and entitled to vote at the Special Meeting, meaning that [•] shares of Company Common Stock must be represented virtually or by proxy at the Special Meeting to have a quorum. In the event that a quorum is not present at the Special Meeting, it is expected that the meeting will be adjourned to solicit additional proxies to approve the Merger Agreement Proposal.

Vote Required; Abstentions and Broker Non-Votes

The affirmative vote of a majority in voting power of the outstanding shares of Company Common Stock entitled to vote as of the close of business on the Record Date is required to adopt the Merger Agreement. As of the close of business on the Record Date, [•] shares constitute a majority of the issued and outstanding shares of Company Common Stock. Adoption of the Merger Agreement by DoubleVerify Stockholders is a condition to the Closing.

Approval of the Compensation Proposal, on a non-binding, advisory basis, requires, assuming a quorum is present, the affirmative vote of a majority in voting power of the outstanding shares of Company Common Stock present in person or represented by proxy and entitled to vote on the matter at the Special Meeting. The approval of the Compensation Proposal is on a non-binding, advisory basis and is not a condition to the Closing.

Approval of the Adjournment Proposal to adjourn the Special Meeting (a) when a quorum is present, requires the affirmative vote of the holders of a majority in voting power of the outstanding shares of

TABLE OF CONTENTS

Company Common Stock represented at the Special Meeting (present virtually or represented by proxy) and (b) when a quorum is not present, the Chairman of the Special Meeting or the affirmative vote of the holders of a majority in voting power of the outstanding shares of Company Common Stock represented at the Special Meeting (present virtually or represented by proxy) may adjourn the Special Meeting to another place, if any, date and time.

The Company does not expect that banks, brokers and other nominees will have discretionary authority to vote on the matters that will be presented at the Special Meeting under applicable stock exchange rules. As a result, the Company does not expect brokers will be able to vote your shares of Company Common Stock at the Special Meeting without receiving instructions. Failure to instruct your broker on how to vote your shares of Company Common Stock is expected to have (i) the same effect as a vote “AGAINST” the Merger Agreement Proposal, and (ii) assuming a quorum is present, no effect on the vote for the Compensation Proposal or the Adjournment Proposal.

Parties Involved in the Merger

DoubleVerify Holdings, Inc.

Neptune BidCo US Inc.

Parent was formed in Delaware on March 17, 2022, for the purpose of effecting the acquisition of Nielsen Holdings plc and related financing transactions. Since the completion of the acquisition of Nielsen Holdings plc, Parent has served as the parent company of Nielsen. For more than 100 years, Nielsen has been a global leader in audience measurement, data, and analytics.

On the terms and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, and in accordance with the DGCL, Merger Sub will merge with and into DoubleVerify, with DoubleVerify continuing as the Surviving Corporation and a wholly owned subsidiary of Parent. As a result of the Merger, Company Common Stock will no longer be publicly traded, and will be delisted from the NYSE. In addition, Company Common Stock will be deregistered under the Exchange Act, and DoubleVerify will no longer file periodic reports with the SEC with respect to Company Common Stock. If the Merger is completed, you will not own any shares of the capital stock of the Surviving Corporation.

TABLE OF CONTENTS

The Effective Time will occur upon the filing of a duly executed certificate of merger with the Secretary of State of the State of Delaware (or at such later date or time as may be specified in the certificate of merger and agreed to in writing by the parties to the Merger Agreement in accordance with the DGCL).

Effect on DoubleVerify if the Merger is Not Completed

If the Merger Agreement is not adopted by the DoubleVerify Stockholders, or if the Merger is not completed for any other reason:

•

the Company Board will continue to evaluate and review DoubleVerify’s business operations, strategic direction and capitalization, among other things, and will make such changes as are deemed appropriate (irrespective of these efforts, it is possible that no other transaction acceptable to the Company Board would be offered or that DoubleVerify’s business, prospects and results of operations would be adversely impacted); and

under certain specified circumstances, DoubleVerify may be required to pay Parent the Company Termination Fee and Parent may be required to pay DoubleVerify the Parent Termination Fee.

Each vested, in-the-money Company Stock Option, including awards that vest in connection with the Closing, will be cashed out for its aggregate spread value (based on the excess of the Merger Consideration over the per-Share exercise price and the number of shares of Company Common Stock underlying such Company Stock Option). Each unvested, in-the-money Company Stock Option will be converted to a Cash Replacement Award equal to its aggregate spread value which will vest and be paid out on the same vesting terms that applied to the corresponding Company Stock Option. All underwater Company Stock Options (whether vested or unvested) will be canceled for no consideration.

•

Each vested Company RSU, including each award that vests in connection with the Closing, will be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such vested Company RSU. Each unvested Company RSU will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of unvested shares of Company Common Stock subject to such Company RSU, which will vest and be paid out on the same vesting terms that applied to the corresponding Company RSU.

•

Each Company PSU as to which the applicable performance-based vesting conditions have been satisfied and that remain subject solely to service-based vesting conditions, will, to the extent vested as of immediately prior to the Effective Time, be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such vested Earned Company PSU. Each Earned Company PSU that does not vest in connection with the Closing will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such unvested Earned Company PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Earned Company PSU. Each Company PSU that is not an Earned Company PSU will be converted into a Converted PSU with respect to the number of shares of Company Common Stock determined by the Compensation Committee based on performance through the Effective Time, in accordance with the underlying award agreement, subject to Parent’s review and reasonable comment. Each Converted PSU will be converted into the right to receive a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such Converted PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Converted PSU.

•

All Cash Replacement Awards will accelerate upon a severance-eligible employment termination within twelve months following the Effective Time, or the holder’s death.

Background of the Merger

The following chronology summarizes the key meetings and events that led to the signing of the Merger Agreement. The following chronology does not purport to catalogue every conversation among the Company, members of the Company’s management team, the Company Board, Parent or any other parties and the respective advisors or representatives of each of the foregoing.

TABLE OF CONTENTS

As part of the Company’s continuing effort to strengthen its business and enhance shareholder value, the Company Board and members of the Company’s management team regularly evaluate the Company’s long-term strategic plan, business prospects, financial performance and operations, as well as the Company’s strategic and competitive position within the digital advertising industry. In connection with this ongoing review, the Company Board and the members of the Company’s management team periodically evaluate and discuss the Company’s capital structure and potential strategic alternatives, transactions and other tactical opportunities, including potential business combinations, strategic partnerships, and other extraordinary corporate transactions. The Company Board and members of the Company’s management team also often receive input from financial, strategic, and legal advisors with respect to such matters.

Since the beginning of 2025, from time to time, the Company Board and members of the Company’s management team met with various investment banks and financial advisors, including representatives of PJT Partners, to discuss the Company’s businesses, industry dynamics, and market trends and developments. Given the qualifications, experience and reputation of PJT Partners and its knowledge of the Company’s businesses and the industries in which the Company operates, the Company Board and members of the Company’s management team also periodically sought the perspectives of PJT Partners regarding the Company’s capital structure and potential strategic alternatives that the Company might consider to enhance shareholder value.

In January 2025, understanding that a strategic party’s (“Party A”) board of directors was considering a sale of Party A’s business, the Company began to assess a possible acquisition of Party A. Over the course of early 2025, members of the Company’s management team and the Company Board continued to discuss the possible acquisition of Party A with several investment banks, including PJT Partners.

On January 17, 2025, the Company retained Paul Hastings LLP (“Paul Hastings”) as outside legal counsel in connection with a potential strategic transaction involving the Company.

On April 16, 2025, Robert Davis Noell, the Company’s Chairperson and a Senior Managing Director of Providence Equity Partners L.L.C. (“Providence”), in his capacity as the Company’s Chairperson, held a meeting in Chicago with representatives of Party A’s then largest shareholder (“Party A Majority Shareholder”), which also has representation on Party A’s board of directors, to discuss, among other things, a possible acquisition of Party A by the Company, and certain challenges that would arise in connection with such an acquisition, including in respect of regulatory matters.

On April 17, 2025, the Company Board held a meeting, via videoconference, attended by members of the Company’s management team and representatives of a certain investment bank (“Investment Bank #1”), to discuss various strategic alternatives, including the potential acquisition of Party A. At such meeting Investment Bank #1 gave a presentation on strategic alternatives and, following discussion by the Company Board and members of the Company’s management team, the Company Board authorized Mr. Noell, in his capacity as the Company’s Chairperson, to engage with Party A and its shareholders on a possible acquisition of Party A.

On April 30, 2025, the Company Board held a meeting in Miami, attended by members of the Company’s management team. At such meeting, members of the Company’s management team discussed with the Company Board potential M&A opportunities for the Company and the current regulatory environment for M&A, which included a discussion of the potential acquisition of Party A. Following the discussion, the Company Board directed members of the Company’s management team to further investigate a possible acquisition of Party A and to make a determination on the feasibility and benefits of such acquisition.

On May 9, 2025, the Nominating and Corporate Governance Committee of the Company Board (the “NomGov Committee”) held a meeting, via videoconference, attended by members of the Company’s management team. At such meeting, the NomGov Committee discussed the formation of a committee of the Company Board (the “Special Committee”) to review, consider, and negotiate certain terms of, and take certain actions on behalf of the Company with respect to, a possible acquisition of Party A. Following discussion, at such meeting the NomGov Committee recommended to the Company Board that the Special Committee be formed.

On May 16, 2025, the Company Board, acting by unanimous written consent, established the Special Committee. The Company Board determined that the Special Committee would consist of Scott Wagner, Gary Swidler, and Kelli Turner (collectively, the “Special Committee Members”), and determined that the

Special Committee Members were disinterested in the potential acquisition of Party A. The Company Board also selected Mr. Wagner as Chairperson of the Special Committee. In June 2025, members of the Company’s management team concluded their investigation of the benefits and feasibility of a possible acquisition of Party A, which the Company Board directed members of the Company’s management team to undertake pursuant to the instructions of the Company Board during its meeting on April 30, 2025. Members of the Company’s management team concluded that, based on their review of the possible acquisition at this time, including their review of the publication of news stories that made public the issuance of a Civil Investigative Demand by the Federal Trade Commission to Party A and other companies in the digital advertising space and certain other matters, the Company should pause its pursuit of the possible acquisition of Party A.

On July 23, 2025, the Company Board held a regular meeting, via videoconference, attended by members of the Company’s management team. At such meeting, the Company Board further discussed the potential for a possible acquisition of Party A, and certain members of the Company’s management team recommended to the Company Board that the Company should not currently reengage on a pursuit of such transaction for several reasons, including (i) external political issues impacting Party A, (ii) concerns over the future strategic value of such transaction given changing dynamics in the digital advertising ecosystem, and (iii) the potential for a prolonged and uncertain regulatory approval process for such transaction. Members of the Company’s management team indicated to the Company Board that it would continue to monitor the situation for changes that could cause the Company to re-engage with Party A.

On September 24, 2025, it was publicly announced that Party A had been acquired by a private equity sponsor (“Party A Sponsor”).

On October 23, 2025, the Company Board held a regularly scheduled meeting, via videoconference, attended by members of the Company’s management team. At such meeting, the Company Board discussed (i) potential strategic alternatives for the Company, including a potential sale of the Company, in light of several recent developments, including the acquisition of Party A by Party A Sponsor, developments in artificial intelligence, continued pressure on the Company’s stock price, and sustained competitive pressure in the advertising measurement industry, and (ii) the continued potential role of the Special Committee following the conclusion of the evaluation of the possible acquisition of Party A by the Company and the potential role of the Special Committee in a process to evaluate other strategic alternatives, including the potential Company sale process contemplated at this meeting. Following this discussion, the Company Board resolved to (i) expand the authority of the Special Committee to, among other things, review, consider and evaluate strategic alternatives for the Company and any related matters arising from such strategic alternatives, including potential mergers, acquisitions, debt financings, and stock repurchases, (ii) declare the Special Committee disinterested with respect to a potential strategic transaction involving the Company, and (iii) appoint Gary Swidler as the Chairperson of the Special Committee going forward. During this meeting, Mr. Noell discussed with members of the Company’s management team and the other members of the Company Board Providence’s potential participation in a strategic transaction involving the Company. Mr. Noell informed members of the Company’s management team and the Company Board that Providence did not have an interest in acquiring control of the Company at such time but that Providence may have an interest in participating in a potential transaction with a third-party bidder.

On November 21, 2025, the Special Committee held a meeting, via videoconference, at which representatives of Paul Hastings and PJT Partners were present. At the meeting, representatives of PJT Partners provided to the Company Board their preliminary perspectives on the Company, including a review of the Company’s historical share price performance and their preliminary observations on the Company’s initial preparation for a sale process, including a potential sale of the Company and the Company’s long-term outlook as a stand-alone entity. Representatives of PJT Partners also presented an overview of Party A’s recently announced take-private transaction and a preliminary assessment of financial sponsors and strategic counterparties that may be interested in a potential strategic transaction involving the Company. Following PJT Partners’ presentation, the Special Committee discussed the impact that a potential take-private transaction could have on the Company and ways to differentiate the Company’s process from recent comparable take-private transactions in the industry. Following such discussions, representatives of Paul Hastings provided members of the Special Committee an overview of their fiduciary duties under Delaware law and discussed process and timing considerations in connection with a potential strategic transaction involving the Company. Following this discussion, the Special Committee directed PJT Partners to establish a list of potential bidders with respect to a potential strategic transaction involving the Company.

TABLE OF CONTENTS

On November 24, 2025, the Company Board held a special meeting, via videoconference, to discuss the process relating to a potential strategic transaction involving the Company. Members of the Company’s management team and representatives of Paul Hastings and PJT Partners attended the meeting. Representatives of Paul Hastings provided members of the Company Board an overview of their fiduciary duties under Delaware law and discussed process and timing considerations in connection with a potential strategic transaction involving the Company. Following the presentation from Paul Hastings, the Company Board discussed the respective roles of the Special Committee and the Company Board in connection with a potential strategic transaction, including determining that the Company Board would be regularly briefed by members of the Company’s management team and the Special Committee in connection with any discussions relating to a potential strategic transaction involving the Company, which may involve both strategic and sponsor bidders. Following this discussion, Mark Zagorski, the Chief Executive Officer of the Company, and PJT Partners provided an update on the Company’s strategic review process, which included a discussion of a potential take-private transaction and potential counterparties that may be interested in a strategic transaction involving the Company. Following the presentation, each of the directors who were previously, or who were currently, associated with Providence, Mr. Noell, Laura Desmond, and Lucy Stamell Dobrin, excused themselves from the meeting given Providence’s possible involvement in a potential transaction in a sale of the Company. The Company Board then engaged in a break-out session to discuss the Company’s sale review process further. In addition, Paul Hastings presented to the remaining members of the Company Board certain “rules of the road” regarding communications with Providence and directors associated with Providence during a sale process given the possibility of Providence’s participation in a transaction with a third-party bidder. Following this discussion, the Company Board directed PJT Partners and the Company’s management team to further explore a potential sale transaction involving the Company, including by preparing materials to be used by the Company to solicit proposals from prospective counterparties with respect to such a transaction.

On December 12, 2025, the Company Board held a regularly scheduled meeting, via videoconference, attended by members of the Company’s management team. At such meeting, members of the Company’s management team presented to the Company Board an overview of the M&A landscape in the digital advertising industry and provided an update on the potential sale process. Among other things, the Company Board discussed (i) the Company’s lower-than-expected Q4 2025 earnings, and (ii) appropriate timing to distribute materials for such potential sale process in light of such earnings. Following the Company Board’s consideration of the Company’s lower-than-expected Q4 2025 earnings, the Company Board determined to delay the launch of such sale process until the Company could determine whether its Q1 2026 earnings would be in line with expectations.

On January 22, 2026, and February 18, 2026, the Company Board held regularly scheduled meetings, attended by members of the Company’s management team. At such meetings, members of the Company’s management team presented to the Company Board an overview of Q1 2026 performance to date and provided an update on the potential sale process.

On both February 23, 2026 and March 13, 2026, the Special Committee held meetings, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners.

On March 20, 2026, the Special Committee held a meeting attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, members of the Company’s management team presented a preliminary version of the five-year financial model prepared in connection with a potential strategic transaction involving the Company. Following a discussion of the inputs and assumptions of such financial model, the Special Committee directed members of the Company’s management team to finalize such financial model and related materials for use in the potential sale process involving the Company and to prepare a full presentation outlining a proposed sale process for the next meeting of the Special Committee. At this meeting, members of the Company’s management team, with the assistance of PJT Partners, also provided an update on preliminary discussions with Party C, Party A Sponsor, Party B and a private equity sponsor (“Party D”) to gauge interest in a potential strategic transaction involving the Company.

On April 6, 2026, the Special Committee held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, representatives of PJT Partners provided an update on the process relating to a potential strategic transaction involving the Company and proposed an outreach plan for engaging with potential bidders. The Special Committee determined that such process should include (i) an initial outreach to solicit interest during the week of April 7, 2026, (ii) management presentations during the weeks of April 13, 2026 through April 27, 2026 to parties that had executed a confidentiality agreement and expressed an interest in a potential strategic transaction, (iii) distribution of the Company’s financial model to certain bidders following such presentations, and (iv) population of a virtual data room (the “Data Room”) to assist potential bidders with their diligence process. The Special Committee discussed proposed talking points for initial outreach to potential bidders and discussed the scope of the outreach, including a proposed list of financial sponsors and strategic counterparties it would direct PJT Partners to approach. In addition, the Special Committee and members of the Company’s management team discussed general strategy for the outreach to potential bidders with representatives of Paul Hastings and PJT Partners and concluded that a targeted outreach to a specific set of financial sponsors and strategic counterparties would give the Company the best opportunity to run a successful process and receive a compelling proposal while limiting the leak risk and potential disruption to the business inherent in a broader process. As part of those discussions, the Special Committee and members of the Company’s management team reviewed PJT Partners’ proposed list of potential counterparties with whom to initiate outreach. The Special Committee determined to focus outreach on financial sponsors and strategic counterparties that (i) had operations in the advertising technology industry or, in the case of financial sponsors, had invested in such industry, (ii) were believed to have submitted a bid during the Party A sale process or to have otherwise participated in such process, and (iii) had not made a public statement regarding their intention to cease making investments in the advertising technology sector. Following this discussion, the Special Committee approved a list of counterparties with whom to initiate outreach and directed PJT Partners and members of the Company’s management team to execute on the outreach plan outlined by the Special Committee.

Also following this discussion, at the direction of the Special Committee, members of the Company’s management team, with assistance of PJT Partners, began developing materials for use in connection with a potential sale process, including a confidential information memorandum and the Company management team’s detailed financial model.

In addition, certain representatives of Providence reiterated to the Special Committee that Providence continued to have no intention to acquire control of the Company but would potentially explore participating in a transaction involving third-party bidders to the extent it facilitated a sale of the Company. Following this discussion, the Special Committee directed PJT Partners and members of the Company’s management team to continue to execute on the outreach plan previously approved by the Special Committee.

Letter was subject to approval by the Board of Directors of Party A and approval by the investment committee of Party A Sponsor. The May 27 Letter indicated that Party A targeted execution of a definitive agreement within 45 days following completion of commercial due diligence.

In addition, Nicola Allais, the Company’s Chief Financial Officer, provided an update on the Company’s lowered Q2 2026 revenue performance expectations. In response to Party A Sponsor requesting that the Company provide additional materials to Party A in connection with Party A’s due diligence review, the Special Committee discussed potential challenges and concerns with sharing additional diligence materials with Party A at that stage and whether the Company could sufficiently address such concerns through execution of a “clean team” confidentiality agreement given the competitive landscape in the advertising measurement industry and Party A’s status as a direct competitor to the Company in several segments. The Special Committee determined that the Company should enter into a “clean team” confidentiality agreement with Party A, and the Company could provide additional limited due diligence information, as appropriate. Following discussion, the Special Committee discussed proposed responses to both Nielsen and Party A and directed PJT Partners to indicate to Nielsen that the Special Committee expected a higher price from Nielsen and a shorter diligence period. The Special Committee also discussed the potential participation by Providence in a transaction with a bidder and the appropriate approach to information sharing with Providence during due diligence.

On May 29, 2026, representatives of PJT Partners held a videoconference with representatives of Nielsen and Elliott to deliver feedback on its proposal in connection with the Company’s sale process.

On June 1, 2026, the Company began providing access to a “Phase II” Data Room to Nielsen, with a plan to provide additional information in such Data Room upon the parties’ subsequent entry into a “clean team” confidentiality agreement. The additional diligence materials would be restricted in accordance with such “clean team” confidentiality agreement.

On June 2, 2026, the Company Board held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, representatives of PJT Partners provided the Company Board with a comparison of the May 20 Letter and the May 27 Letter. The Company Board also discussed the parameters for Providence to have discussions with Nielsen regarding Providence’s potential participation in a transaction. Prior to such discussions, Mr. Noell, Ms. Desmond, and Ms. Dobrin excused themselves from the meeting, given Providence’s possible involvement in a potential transaction involving the Company. The Company Board and members of the Company’s management team then discussed with PJT Partners strategy and next steps with each bidder. Following discussion, the Company Board provided PJT Partners with key messages the Company Board wanted delivered to each bidder and directed PJT Partners to facilitate further diligence by Nielsen and Party A.

On June 4, 2026, to facilitate Nielsen’s ongoing due diligence of the Company, the Company and Nielsen entered into a “clean team” confidentiality agreement containing certain restrictions on Nielsen’s ability to share and access certain commercially sensitive information.

On June 5, 2026, the Company segregated certain due diligence materials into a separate “clean room” and provided such materials only to certain representatives of select bidders, including Nielsen, that had executed a clean team addendum to their respective confidentiality agreements, with access to certain of information in such “Phase II” Data Room restricted in accordance with the parties’ “clean team” confidentiality agreement.

Between June 11, 2026 and June 16, 2026, the Company hosted, via videoconference, various diligence sessions with Nielsen, to discuss, among other things, the Company’s cost structure, customers, products, and technology infrastructure.

TABLE OF CONTENTS

On July 10, 2026, the Special Committee held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, representatives of PJT Partners presented a summary of the July 9 Letter to the Special Committee and provided an update on the status of Nielsen’s proposal. Following such summary, representatives of Paul Hastings provided a summary of the regulatory risks associated with a transaction with Party A and noted that the July 9 Letter did not indicate that Party A was willing to agree to a reverse termination fee for an antitrust failure and did not describe the regulatory commitment Party A would be willing to undertake. The Special Committee discussed the relative closing uncertainty associated with each bidder, noting that Party A presented more closing risk and a more challenging regulatory profile given overlaps in the parties’ respective businesses. The Special Committee also considered that the July 9 Letter did not include details regarding Party A’s potential sources of debt or equity financing and the risks associated with such lack of clarity, including that Party A may not have the ability to deliver debt and equity commitment papers at signing and to otherwise finance the potential strategic transaction on a timely basis. Following discussion, the Special Committee directed PJT Partners to (i) request a specific proposal on regulatory and financing matters from Party A, and (ii) share a version of the Merger Agreement with Party A. Later on July 10, 2026, at the direction of the Special Committee, representatives of PJT Partners had a meeting, via videoconference, with representatives of Elliott.

On July 14, 2026, at the direction of the Special Committee, representatives of PJT Partners shared a slightly modified version of the draft Merger Agreement with WFG and Party A (the “Party A Bid Draft”), which contained substantially the same terms as the Bid Draft provided to Nielsen but (i) contemplated a one-step reverse triangular merger transaction structure, as the accelerated timing to closing of a two-step merger would not be possible with Party A given the expected time necessary for Party A to satisfy regulatory conditions to closing, and (ii) included a Parent Termination Fee triggered by failure to obtain regulatory approvals.

On July 14, 2026, Gibson Dunn & Crutcher LLP (“GDC”), legal counsel to Nielsen, delivered a list of Nielsen’s positions with respect to certain matters raised in the Bid Draft (the “July 14 Issues List”). Among other things, such list provided for (i) a one-step reverse triangular merger structure as opposed to a two-step transaction structure, (ii) a “sponsor”-style transaction providing for a termination fee in the event of a financing failure and limited specific performance rights, (iii) conversion of all equity-based awards into cash awards paid in accordance with such awards’ original vesting terms, (iv) removal of the “hell or high water” regulatory efforts standard (v) a removal of the “clear skies” covenant in the Bid Draft, and (vi) an indication that the amount of the Company Termination Fee remained subject to review.

On July 15, 2026, the Company Board held a meeting, via teleconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, PJT Partners provided a summary of the status of the sale process, including by comparing the terms of the May 20 Letter and the July 9 Letter and by summarizing recent discussions with the bidders. PJT Partners reported that Nielsen was expected to submit a revised bid by July 17, 2026 and noted that (i) Nielsen had conducted substantial due diligence and Party A had only conducted a preliminary review of the diligence materials to date, and (ii) Nielsen had provided detail to the Company on its sources of equity and debt financing, and Party A had not yet provided such information. Paul Hastings then provided an overview of each bidder’s relative regulatory profile and the anticipated closing certainty associated with their respective proposals. Following such summary, the Company Board discussed valuation considerations, the relative merits of the two proposals, and timing.

Between July 16, 2026 and July 29, 2026, the Company conducted several management meetings to cover due diligence topics with representatives of Nielsen, Brookfield and Elliott, including legal, finance, tax, and human resources matters.

On July 16, 2026, Paul Hastings delivered to GDC a document containing the Company’s responses to the July 14 Issues List. Among other things, such document specified that the Company would accept the

TABLE OF CONTENTS

following terms in connection with a potential strategic transaction: (i) a “strategic”-style deal containing a full specific performance remedy; (ii) a full acceleration and cash-out of all equity-based awards outstanding as of closing of the transaction; and (iii) a requirement that Nielsen’s revised draft of the Merger Agreement include a specific proposal regarding the antitrust efforts covenant. In addition, such document specified that the Company would require a proposal from Nielsen on the amount of the Company Termination Fee in Nielsen’s markup to the Merger Agreement. Shortly thereafter, representatives of Paul Hastings also delivered to GDC an initial draft of the Company Disclosure Letter.

On July 17, 2026, Nielsen submitted a revised indication of interest in connection with the sale process (the “July 17 Letter”). In the July 17 Letter, Nielsen reduced its proposed purchase price from $14.00 per share to $13.20 per share in cash, and noted structural headwinds facing the Company and whether the Company could sustain historical growth and profitability as the advertising landscape continued to evolve. The July 17 Letter also indicated that Nielsen had completed its business diligence and could complete confirmatory diligence by July 31, 2026. The July 17 Letter otherwise contained substantially the same terms and conditions as set forth in the May 20 Letter for a proposed transaction and requested exclusivity for a period of fifteen (15) business days to execute definitive documentation. The July 17 Letter also included, as exhibits, certain “highly confident” letters from Nielsen’s financing sources and specified that Nielsen expected to deliver fully executed debt commitment papers from its financing sources prior to the execution of definitive transaction documentation.

On July 19, 2026, the Special Committee held a meeting, via teleconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, representatives of PJT Partners presented a comparison of both proposals (with respect to Nielsen, as described in the May 20 Letter and July 17 Letter, and with respect to Party A, as described in the May 27 Letter, the June 18 Letter and the July 9 Letter). PJT Partners noted that (i) Nielsen had signaled that there would be room to increase its proposed price per share, had secured “highly confident” financing letters from three major financial institutions, and had completed a detailed due diligence work plan, and (ii) Party A indicated that it still needed to complete its due diligence review, had not yet provided a definitive proposal on antitrust risk allocation, signaled that it may experience difficulty securing debt financing, and also signaled that executing definitive documentation on the Company’s proposed timeline would be challenging. Following such summary, the Special Committee discussed the relative closing risks associated with each bidder, the Company’s lowered second quarter financial results and the potential impact to the Company’s stock price (and consequently the bids) following the public disclosure of its lower-than-expected Q2 2026 financial results. The Special Committee then directed PJT Partners to provide the Special Committee’s feedback to each of Party A Sponsor (on behalf of Party A) and Nielsen and solicit best and final proposals from both bidders. The Special Committee also directed PJT Partners to inform Nielsen that the Company could not accept the proposal for exclusivity at this time.

On July 20, 2026, as directed by the Special Committee, PJT Partners verbally delivered feedback, via videoconference, to each of Party A Sponsor (on behalf of Party A) and Nielsen, requesting that each bidder deliver a markup of the Bid Draft or the Party A Bid Draft, as applicable, by July 22, 2026, to have executed commitments in hand and that the Company remained interested in entering into a definitive agreement shortly after July 30, 2026. In such conversations, as directed by the Special Committee, PJT Partners specified (i) that the Company expected both Nielsen and Party A to deliver their best and final positions on the regulatory efforts provisions and on termination fees, (ii) to Party A that the Company would require additional feedback on valuation by July 24, 2026 and in any event prior to the Company providing access to further diligence information, and (iii) to Nielsen that the Company would not accept the proposal for exclusivity at this time. During such videoconference, Party A Sponsor indicated to PJT Partners that it would have difficulty meeting such proposed timing and would need more time to deliver further feedback on valuation. PJT Partners promptly notified the Special Committee of Party A Sponsor’s indications.

Also on July 20, 2026, WFG delivered a list of issues raised by the Party A Bid Draft and Party A’s responses to those issues, which included, among other things, (i) an expectation that the Merger Agreement contain a “sponsor”-style deal rather than a “strategic” deal, (ii) that Party A would deliver a proposal on the antitrust efforts covenant once additional diligence had been conducted, and (iii) that Party A would need to review the Company’s underlying equity awards before making a proposal on treatment of such awards. Between July 20, 2026 and July 23, 2026, representatives of Paul Hastings held several videoconferences with representatives of WFG to discuss such issues.

On July 29, 2026, the Special Committee held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, Mr. Zagorski provided an update on a conversation Mr. Zagorski had with Mr. Rao, and discussion with a representative of Party A Sponsor. Mr. Zagorski provided an update on the status of each bidder’s current considerations in connection with a potential strategic transaction involving the Company, including the status of discussions among representatives of PJT Partners and representatives of Party A Sponsor. Following such update, the Special Committee discussed with its advisors potential messaging to be delivered to each bidder with a view to maintaining the competitive dynamic in the process and meeting the timing goal of a signing prior to the announcement of the Company’s Q2 earnings.

On July 30, 2026, Nielsen submitted a revised indication of interest in connection with the sale process reaffirming its prior offer of $13.20 per share, in cash (the “July 30 Letter”). The July 30 Letter otherwise contained substantially the same terms and conditions for a potential strategic transaction but cited certain liabilities of the Company that Nielsen believed it had identified and the lowered Q2 2026 revenue performance expectations as reasons that prevented Nielsen from increasing its bid. In addition, the July 30 Letter indicated that Nielsen would shortly share a set of fully negotiated debt commitment papers contemplating $1.8 billion of debt financing sourced from various lenders.

On July 31, 2026, the Special Committee held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, representatives of PJT Partners provided an update on the proposals received from Party A and Nielsen. Representatives of PJT Partners noted that Party A (i) had not yet provided an update on its confirmed valuation of the Company, (ii) was behind Nielsen with respect to its due diligence review on the Company and on its proposed financing, and (iii) had not yet provided clarity on the timing of a potential signing date with respect to definitive documentation for a potential strategic transaction. Following such update, the Special Committee discussed with PJT Partners and Paul Hastings the timing of the Company’s next earnings call and the risk that the lower-than-expected Q2 earnings could both exert significant downward pressure on the Company’s stock price and risk jeopardizing the ability of the Company to maintain the per share price in the bids received from both Nielsen and Party A. Following the discussion, the Special Committee directed (i) PJT Partners to respond to Nielsen’s latest proposal by insisting that Nielsen match its prior offer of $14.00 per share, in cash, and (ii) Paul Hastings to further resolve open issues in the Merger Agreement with GDC. Later that day, PJT Partners provided an updated relationship disclosure letter to the Special Committee.

On July 30, 2026, representatives of Paul Hastings held a virtual videoconference with representatives of GDC to discuss the remaining open issues in the Merger Agreement.

Also on July 31, 2026, as directed by the Special Committee, representatives of PJT Partners held a meeting, via videoconference, with representatives of Nielsen and Elliott. At such meeting, as directed by the Special Committee, PJT Partners indicated that (i) the Special Committee was not prepared to recommend a transaction with Nielsen at a price of $13.20 per share, (ii) the potential liabilities and issues identified in the July 30 Letter were not credible, and (iii) the Company would expeditiously work towards definitive documentation for a transaction at a price of $14.00 per share. In addition, as directed by the Special Committee, PJT Partners indicated that the Company would require the following terms: (i) a Parent Termination Fee of 6% of implied equity value, (ii) a Company Termination Fee of 2.5% of the implied equity value, (iii) uncapped damages for a willful breach by Nielsen, (iv) that unvested equity awards would convert into cash awards that accelerate upon a termination of the applicable employee, and (v) a regulatory efforts covenant requiring Nielsen to agree to conduct remedies binding on Nielsen’s business.

Also on July 31, 2026, representatives of WFG delivered a list of issues associated with a potential strategic transaction. Among other things, in such list Party A proposed (i) a Parent Termination Fee equal to

5% of implied equity value, (ii) a limited regulatory efforts covenant with an express provision that Party A would have no obligation to litigate to resolve regulatory impediments to closing, and (iii) an outside date of twelve months from the date of signing of the Merger Agreement, with one automatic three-month extension if all conditions (other than regulatory approvals) were satisfied at the initial twelve-month outside date. Later that day, representatives of WFG held a meeting, via videoconference, with representatives of Paul Hastings to discuss such issues.

Also on July 31, 2026, representatives of Paul Hastings held a virtual videoconference with representatives of WFG to discuss the issues list provided by WFG. During such videoconference, WFG indicated that Party A had not yet conducted an extensive review of the due diligence materials to date and that Party A would only be able to execute a transaction in late August (which was significantly later than the timing on which Nielsen was prepared to transact). In addition, during such videoconference, WFG did not indicate their expected timing of delivery of a revised draft of the Merger Agreement.

On August 1, 2026, representatives of Paul Hastings held a meeting, via videoconference, with representatives of GDC to discuss open issues in the Merger Agreement.

On August 2, 2026, Paul Hastings delivered a revised draft of the Merger Agreement to GDC.

Also on August 2, 2026, the Company Board held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, Mr. Zagorski and representatives of PJT Partners and Paul Hastings provided an update on recent conversations with Nielsen, including noting that they expected to receive a revised bid from Nielsen at $13.50 per share, in cash. In addition, it was discussed with the Company Board that, among other things, (i) Party A indicated that it needed additional time and had further information requests that would need to be addressed for Party A, in each case, to complete its due diligence, (ii) Party A indicated that Party A would need approximately 20 to 30 more days to arrange its financing for a potential strategic transaction, (iii) Party A continued to insist on a Parent Termination Fee of 5% of implied equity value, notwithstanding the significantly higher regulatory risk inherent in a transaction with Party A, and (iv) Party A had still not provided an updated valuation in writing and, as such, Party A’s last formal bid remained a range of between $13.00 and $13.99 per share in cash. Following such discussion, representatives of Paul Hastings again reviewed the Company Board’s fiduciary duties in this context, which included, among other things, the considerations that may be considered as part of the Company Board’s analysis of the relative value of competing cash bids. These included, among other things, (i) the relative certainty that a bidder will ultimately obtain financing and execute on a proposal, (ii) the fact that a bid may have materially higher closing risk than the other, and (iii) the fact that a losing bidder would have another opportunity to make a more compelling bid after signing and before a shareholder vote to approve the transaction. The representatives of Paul Hastings then reviewed the then-current terms of the draft Merger Agreement with Nielsen, noting the open points that needed resolution before signing. Following such discussion, the Company Board discussed several matters relating to the proposed transaction, including, among other things, (i) the importance that the Company sign and announce a definitive transaction agreement prior to the announcement of the Company’s Q2 earnings, given the potential significant downward pressure on the Company’s stock price, (ii) the potential for bidders to reduce or withdraw their bids following the announcement of the Company’s Q2 earnings, and (iii) the continued uncertainty surrounding Party A’s proposal, including as to price, availability of financing, and regulatory risk and Party A’s continued failure to address or mitigate such risks despite several overtures, at the direction of the Special Committee, by members of the Company’s management team, PJT Partners and Paul Hastings. Following discussion, the Company Board, among other things, directed Mr. Noell, in his capacity as the Company’s Chairperson, to again seek to increase the bid from Nielsen by discussing directly with Mr. Kerko.

TABLE OF CONTENTS

On August 3, 2026, Nielsen submitted a revised indication of interest in connection with the sale process (the “August 3 Letter”). The August 3 Letter provided for an increased purchase price of $13.50 per share in cash. In addition, in the August 3 Letter, Nielsen (i) agreed to a Parent Termination Fee of 6% and Company Termination Fee of 2.5%, (ii) requested that the Parent Termination Fee be the Company’s sole and exclusive remedy if payable, including for a willful breach by Nielsen, and (iii) provided that unvested equity awards would convert to cash awards that accelerate upon termination of the applicable employee in certain circumstances.

Also on August 3, 2026, GDC delivered initial drafts of the Equity Commitment Letter, Limited Guarantee and Voting and Support Agreement to Paul Hastings.

Also on August 3, 2026, Mr. Noell, in his capacity as the Company’s Chairperson, held a meeting, via videoconference, with Mr. Kerko. At such meeting, Mr. Noell indicated that the Company would require an offer of at least $13.60 per share, in cash, from Nielsen, which Mr. Kerko indicated he would discuss with Elliott and Brookfield.

Between August 3, 2026 and August 6, 2026, Davis Polk & Wardwell LLP, counsel to Providence, and GDC exchanged several drafts of the Voting and Support Agreement.

On August 4, 2026, Mr. Swidler held a follow-up discussion, via teleconference, with a representative of Party A Sponsor regarding the timeline of a potential strategic transaction. During such discussion, Mr. Swidler reiterated that the Company expected Party A to proceed on an expedited timeline, and that Party A continued to be substantially behind other bidders.

Also on August 4, 2026, Party A submitted a revised indication of interest in connection with the sale process (the “August 4 Letter”). The August 4 Letter provided for an increased purchase price of $14.50 per share in cash. The August 4 Letter also expressly provided that Party A would only transact based on the positions set forth in the list of issues delivered by WFG on July 31, 2026. Specifically, Party A insisted on (i) a Parent Termination Fee equal to 5% of implied equity value, (ii) no affirmative obligation to litigate to resolve regulatory issues, and (iii) a twelve-month initial outside date with one automatic three-month extension if all conditions (other than conditions relating to regulatory approvals) were satisfied as of the initial outside date. The August 4 Letter did not indicate Party A’s sources of debt or equity financing for a potential strategic transaction.

Also on August 4, 2026, GDC delivered a revised draft of the Merger Agreement to Paul Hastings. Among other things, such revised draft provided for each of the positions taken by Nielsen in the August 3 Letter and also provided that (i) Nielsen control and direct all matters relating to the parties’ efforts to obtain antitrust clearance, (ii) Nielsen would have no obligation to divest assets in connection with its efforts to obtain regulatory approvals, and (iii) the Parent Termination Fee would be the exclusive remedy of the Company if payable under the Merger Agreement, even in the case of a willful breach by Nielsen.

Also on August 4, 2026, representatives of Paul Hastings delivered a further revised draft of the Company Disclosure Letter to representatives of GDC.

Later on August 4, 2026, the Special Committee held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, representatives of PJT Partners provided an update on the latest proposals received from Party A and Nielsen, including that (i) Party A had delivered a revised offer of $14.50 per share in cash, and (ii) Party A would require an additional 30 days to complete their due diligence and financing and to sign and announce a definitive agreement. Following such update, the Special Committee discussed, among other things, (i) the likelihood that Party A could actually sign a definitive agreement within 30 days given earlier delays in the sales process, (ii) the potential consequences of providing Party A with additional time to sign a definitive agreement, which included the risk that lower-than-expected Q2 earnings may cause both bidders to reduce their bids and that Nielsen may withdraw its bid entirely, and (iii) the regulatory and closing risk associated with a transaction with Party A. Following discussion, the Special Committee directed Mr. Noell, in his capacity as the Company’s Chairperson, to contact representatives of Nielsen to again seek to increase the Nielsen offer and to convene a meeting of the Company Board to further discuss a potential strategic transaction.

TABLE OF CONTENTS

On August 5, 2026, Paul Hastings delivered revised drafts of the Merger Agreement, Equity Commitment Letter, and Limited Guarantee to GDC. Such revised draft of the Merger Agreement proposed, among other things, a cap on the parties’ respective liabilities arising from a willful breach of the Merger Agreement equal to an amount not to exceed (x) $200,000,000, plus (y) the amount of any recovery costs associated with enforcing payment of such fee, plus (z) in the case of a willful breach by Parent, the amount of any the reimbursement and indemnification obligations arising in connection with the Company’s assistance in arranging for the Debt Financing, if applicable. Later that day, representatives of GDC delivered a revised draft of the Company Disclosure Letter to representatives of Paul Hastings.

Also on August 5, 2026, representatives of Elliott held a meeting, via teleconference, with representatives of PJT Partners and indicated that Nielsen would increase the previously proposed purchase price from $13.50 to $13.60 per share, which representatives of PJT Partners promptly relayed to the Company and included in the update at the Company Board meeting.

Also on August 5, 2026, representatives of Paul Hastings held a meeting, via videoconference, with representatives of WFG to discuss, among other things, regulatory matters associated with a potential strategic transaction and other material issues in connection with the most recent draft of the Merger Agreement. At such meeting, representatives of WFG stated that Party A would not have any capacity to increase the amount of the Parent Termination Fee or to further modify the scope of the regulatory efforts covenant binding on Party A.

Also on August 5, 2026, the Company Board held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, Mr. Zagorski, Mr. Campbell, and representatives of PJT Partners provided a status update on the Company’s recent discussions with each of Nielsen and Party A Sponsor, including by providing a comparison of the August 3 Letter and the August 4 Letter and comparing timing, financing, transaction terms and closing certainty reflected in both letters. Among other things, Mr. Zagorski noted that, while the Party A proposal reflected a higher nominal price per share, the proposal from Party A had several issues that Party A had not addressed despite several overtures from the Company and its advisors, including that (i) Party A had not substantively engaged on definitive transaction documentation and many of its positions in its draft Merger Agreement remained subject to further diligence, (ii) members of the Company’s management team did not have confidence that Party A could timely (or ever) execute definitive documentation for a potential strategic transaction, including because Party A had not provided evidence of committed financing and because Party A Sponsor purportedly had issues obtaining committed financing in its acquisition of Party A in 2025, (iii) Party A’s proposal included substantially higher closing risk due to regulatory considerations and Party A had not made a satisfactory proposal to mitigate that risk and Party A’s ability to obtain financing, (iv) Party A informed the Company that it would need an additional 30 days in order to complete Party A’s due diligence review and to finalize any committed financing, (v) Party A’s proposed timing to signing of definitive documentation would follow the announcement of the Company’s lower-than-expected Q2 earnings, which earnings announcement could cause both bidders to reduce or withdraw their bids for the Company, (vi) that Party A would have an opportunity to make an enhanced bid for the Company after signing of a transaction with Nielsen, should they choose to, and that the deal protection provisions contemplated in a transaction with Nielsen would not be preclusive of such a bid, and (vii) Nielsen had indicated that it would not continue in the sale process after the Company announced its Q2 earnings because any associated decrease in the Company’s stock price could impact their financing and because Nielsen would not wait for other bidders to catch up to them on diligence and other matters. Mr. Zagorski and Andy Grimmig, the General Counsel of the Company and Chief Legal Officer, noted that, on the other hand, definitive documentation with Nielsen was substantially advanced, with only a limited number of open issues remaining, and that a transaction with Nielsen presented a substantially lower regulatory risk given the lack of material overlap in the parties’ businesses and a faster timeline to closing and regulatory approval. The Company Board also considered that Nielsen had informed the Company that Nielsen would not wait and would not keep its bid outstanding if a transaction could not be completed on the current contemplated timeline. Following such discussion, representatives of Paul Hastings reviewed with the Special Committee the directors’ fiduciary duties under Delaware law in the context of considering and comparing competing acquisition proposals and a potential sale of the Company. Mr. Grimmig and representatives of Paul Hastings also reviewed the key terms of the definitive transaction documentation with Nielsen and the proposed resolutions of outstanding issues on such documentation. Following discussion, the Company Board directed members of the Company’s

management team, Paul Hastings and PJT Partners to finalize transaction documentation with Nielsen on an expedited basis and to resolve open issues with respect to the August 3 Letter.

On August 6, 2026, GDC delivered a revised draft of the Merger Agreement to Paul Hastings. Among other things, such revised draft of the Merger Agreement provided (i) for an increase to the consideration payable by Nielsen from $13.50 per share to $13.60 per share in cash, (ii) for a reduction in the cap on damages in the event of a willful breach from $200 million to $175 million, (iii) that Nielsen would only need to agree to conduct remedies imposed by a regulator binding on Nielsen and its subsidiaries that were purely administrative in nature, and (iv) that Nielsen would not need to accept conduct or behavioral remedies in connection with its regulatory efforts to the extent such remedies would materially and adversely impact the day-to-day business of Nielsen and its subsidiaries as conducted as of the date of the definitive agreement.

Over the course of the day on August 6, 2026, Paul Hastings, along with members of the Company’s management team, and GDC, along with members of Nielsen’s management team, had several meetings, via videoconference, to finalize the terms of the Merger Agreement and related transaction documents, including the Voting and Support Agreement, the Equity Commitment Letter, and the Limited Guarantee, including to negotiate the cap on damages in the event of a willful breach and the scope of the regulatory efforts covenant binding on the parties.

Later that day on August 6, 2026, Paul Hastings delivered a further revised draft of the Merger Agreement to GDC. In addition, over the course of the day on August 6, 2026, GDC and Paul Hastings subsequently shared various markups of the Company Disclosure Letter, Equity Commitment Letter, and the Limited Guarantee.

Also on August 6, 2026, the Special Committee held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, PJT Partners and Paul Hastings summarized the material terms of the proposed transaction with Nielsen and recent negotiations with Nielsen, including that Nielsen had (i) increased the Merger Consideration to $13.60 per share in cash, and (ii) agreed to a Parent Termination Fee of $144,000,000 (approximately 6% of implied equity value) and a Company Termination Fee of $60,000,000 (approximately 2.5% of implied equity value). In addition, PJT Partners and Paul Hastings reviewed the most recent terms for a potential strategic transaction with Party A and Paul Hastings discussed the considerably heightened regulatory risk for a transaction with Party A and the relatively low Parent Termination Fee offered by Party A. At the request of the Special Committee, representatives of PJT Partners reviewed PJT Partners’ financial analyses in connection with the proposed transaction. At the request of the Special Committee, representatives of PJT Partners then rendered PJT Partners’ oral opinion to the Special Committee and the Company Board (which was subsequently confirmed in writing to the Special Committee and the Company Board) that, as of August 6, 2026, and based upon and subject to, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken by PJT Partners in connection with the opinion (which are stated in its written opinion), the Merger Consideration of $13.60 per share in cash to be received by the holders of shares of the Company’s common stock (other than Excluded Shares and Dissenting Shares) in the Merger was fair to such holders from a financial point of view (such opinion, the “Fairness Opinion”). The full text of PJT Partners’ written opinion, which describes, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the review undertaken by PJT Partners in connection with the Fairness Opinion, is attached as Annex B. Following discussion, the Special Committee unanimously determined that the Merger Agreement, the Merger, and the other Transactions were advisable, fair to, and in the best interests of the Company and its stockholders and unanimously recommended that the Company Board approve the Merger Agreement and the Transactions.

Following the Special Committee meeting, the Company Board held a meeting, via videoconference, attended by members of the Company’s management team and representatives of Paul Hastings and PJT Partners. At such meeting, PJT Partners reviewed the material financial terms of the proposed transaction and the Fairness Opinion. Paul Hastings then reviewed the material terms and conditions of the Merger Agreement, the Voting and Support Agreement, the Equity Commitment Letter, the Limited Guarantee, and the Company Disclosure Letter. In addition, members of the Special Committee confirmed that the Special Committee had unanimously recommended that the Company Board approve the Merger Agreement and the Transactions. Following discussion, the Company Board, acting on the unanimous recommendation of the Special Committee, unanimously determined that the Merger Agreement, the Merger, and the other

TABLE OF CONTENTS

Transactions are advisable, fair to, and in the best interests of the Company and its stockholders, approved and adopted the Merger Agreement and the Transactions, and resolved to recommend that the Company’s stockholders adopt the Merger Agreement.

On August 6, 2026, the parties to the Merger Agreement executed the Merger Agreement and issued a press release announcing the Merger.

Recommendation of the Company Board

Accordingly, the Company Board unanimously recommends, on behalf of DoubleVerify, that you vote (1) “FOR” the Merger Agreement Proposal; (2) “FOR” the non-binding, advisory Compensation Proposal; and (3) “FOR” the Adjournment Proposal.

Reasons for the Merger

At a meeting held on August 6, 2026, the Company Board, acting on the recommendation of the Special Committee, unanimously (i) determined that the Merger Agreement, the Merger, and the other Transactions are fair to, and in the best interests of, the Company and the DoubleVerify Stockholders, (ii) authorized and approved the execution and delivery of the Merger Agreement and the performance by the Company of its covenants and obligations contained in the Merger Agreement and the consummation by the Company of the Transactions, including the Merger, and (iii) resolved to recommend that the DoubleVerify Stockholders approve the adoption of the Merger Agreement and the Transactions, including the Merger, in each case, on the terms and subject to the conditions of the Merger Agreement.

In recommending that the DoubleVerify Stockholders vote in favor of the adoption of the Merger Agreement, the Company Board consulted with the members of the Company’s management team, as well as the Company’s legal and financial advisors, and considered the following factors, which are not intended to be exhaustive and which are not listed in any relative order of importance, all of which the Company Board viewed as generally supporting its determinations and recommendation:

•

Transaction Premium. The fact that the $13.60 per share in cash to be paid as Merger Consideration represents a 22%, 30%, and 30% premium to the price per share of Company Common Stock, based on the volume-weighted average price for the 30, 60, and 90 trading-day periods, respectively, ending on August 5, 2026, the last trading day prior to the date on which the Transactions, including the Merger, were approved by the Company Board. On [•], 2026, the last practicable day before the printing of this proxy statement, the closing price of the Company Common Stock on the NYSE was $[•] per share.

•

Attractive Valuation. The Company Board’s belief that the Merger Consideration provides DoubleVerify Stockholders with attractive value for their Company Common Stock based on, among other things, the current and historical market prices for the Company Common Stock, current industry conditions and the Company Board’s familiarity with the Company’s businesses, operations, prospects, strategic, short- and long-term operating plans, and financial condition, and implies enterprise values of the Company representing multiples of:

•

approximately 8.1 times the Company’s adjusted EBITDA for the last twelve-month period ended June 30, 2026, of approximately $264,000,000 (after adjustment for certain non-recurring items and before stock-based compensation expense); and

•

approximately 7.6 times the Company’s projected adjusted EBITDA for fiscal year 2026 of approximately $283,000,000.

TABLE OF CONTENTS

•

Trading Price. The Company Board’s belief that, if the Company did not enter into the Merger Agreement with Parent, there could be a considerable period of time before the trading price of the Company Common Stock would reach and sustain the Merger Consideration value of $13.60 per share of Company Common Stock.

•

Value Relative to Stand-Alone Prospects. The Company Board’s determination that the Merger Consideration is more favorable to the DoubleVerify Stockholders than the potential value of the shares that would reasonably be expected to result from the Company remaining a stand-alone publicly-traded company in both the short- and the long-term, after taking into account the risks and uncertainties associated with remaining a stand-alone publicly-traded company, including the Company’s business, its competitive position, current industry and financial conditions, and other business, competitive, financial, industry, legal, market and regulatory considerations. In making this determination the Company Board considered, among other things:

•

its assessment of the Company’s historical results of operations, financial performance, financial prospects and financial condition;

•

the challenges the Company has faced in responding to the risks posed by artificial intelligence and the execution risks in its successful further deployment of artificial intelligence;

•

other strategic and financial alternatives reasonably available, including potential expansion opportunities, such as expansion into new business lines, in each case, taking into account execution risks;

•

the Projections, and the execution risks implicit in achieving the Projections, including the risk of an economic downturn, further industry dislocations, or that the Company’s strategic initiatives may (i) not be successful in driving demand for the Company’s products and services, (ii) incur expenses greater than those projected, and (iii) result in increases in revenue with suboptimal margins or that do not occur on the timeline reflected in the Projections, or at all;

•

the macroeconomic factors currently affecting the Company’s industry, including volatile global financial markets and economic conditions, global conflicts and geopolitical uncertainty affecting the Company and its existing and potential customers, and certain other risk factors detailed in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025; and

•

the risks and uncertainties relating to the intensifying competition that the Company faces from both established players and emerging ad verification technologies, coupled with the need for significant ongoing investment in AI-driven measurement, privacy compliance, and global scalability and the impact of these dynamics on the Company’s margins and operational complexity.

•

Negotiations with Parent. The Company Board’s consideration of the course of discussions and negotiations between the Company and Parent, improvements to the terms of Parent’s acquisition proposal in connection with those negotiations, including those ultimately resulting in Parent’s final price of $13.60 in cash per share of Company Common Stock, and the Company Board’s belief that (i) the Company had obtained Parent’s “best and final offer” and the most favorable terms to which Parent was willing to agree, and (ii) further negotiations would create a risk of causing Parent to withdraw Parent’s final offer of $13.60 in cash per share of Company Common Stock and/or to abandon the transaction altogether. For more information, please see the section of this proxy statement captioned “The Merger — Background of the Merger”.

•

Best Value Reasonably Available. The Company Board’s belief that (i) the Merger Consideration represents the highest price that Parent was willing to pay, (ii) the Merger Consideration represents the best value reasonably available to DoubleVerify Stockholders, when taking into consideration the likelihood of consummation of a transaction and the factors set forth under the heading “Lack of Alternative Acquirors” below, and (iii) the Merger Agreement does not preclude the Company Board from, in certain circumstances, considering and responding to unsolicited Acquisition Proposals (as defined in the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Non-Solicitation”) made after the announcement of the entry into the Merger Agreement and before receipt of the Required Company Stockholder Approval.

TABLE OF CONTENTS

•

Strategic Alternative Process. The fact that the Company Board and the Special Committee engaged in extensive discussions and deliberations over a period spanning approximately eighteen (18) months regarding potential strategic alternatives and potential counterparties with members of the Company’s management team and the Company’s legal and financial advisors. In particular, the Company Board considered the fact that the strategic alternative process it conducted began in early-to mid-2025, with the assistance of the Company’s legal and financial advisors, involved contacting potential counterparties and entering into confidentiality agreements with Parent and nine (9) additional potential counterparties (comprising a mixture of strategic and financial counterparties that the Company Board determined would be most likely to have an interest in acquiring, and be able to pay a competitive price, for the Company), providing management presentations to ten (10) potential counterparties, receiving initial non-binding indications of interest from two (2) potential counterparties and receiving two (2) final indications of interest.

•

Lack of Alternative Acquirors. The Company Board’s determination that no alternative party, including strategic buyers (including Party A) and financial sponsors (including, among others, Providence, Party B, Party C, Party D, Party E, Party F, Party G, Party H, and Party I), was likely to enter into a potential transaction at a comparable price and with the same likelihood of consummation as the transaction proposed by Parent, even if the Company were to continue with the strategic alternative process described above and in the section of this proxy statement captioned “The Merger — Background of the Merger” or other solicitation of alternative acquisition proposals, in addition to the potential risk of continuing such process, including in respect of the increased possibility of market rumors, the potential that Parent would abandon negotiations with the Company, and the potential impact of market leaks on the members of the Company’s management team, employees, customers, business partners and other constituencies, and the disruption to the Company’s performance that may result. In making this determination, the Company Board considered, among other things:

•

the fact that a transaction with Parent, given regulatory considerations (including antitrust rules and regulations), provides considerably more certainty and speed to the consummation of the Merger than a potential transaction with other potential bidders, including Party A, and including as a result of the lack of material overlap in the businesses of the Company and Parent;

•

the fact that other bidders, including Party A, had not substantively engaged on definitive transaction documentation and that the Company Board did not have confidence that any such other bidders could timely (or ever) execute definitive transaction documentation for a proposed transaction;

•

the fact that other bidders, including Party A, had not provided evidence of committed financing; and

•

the fact that no bidder, other than Parent, had proposed timing to signing of definitive documentation prior to the announcement of the Company’s lower-than-expected Q2 earnings, which earnings announcement could have led bidders to reduce or withdraw their bids for the Company.

•

Loss of Opportunity. The possibility that, if the Company Board declined to enter into the Transactions, including the Merger, and declined to recommend the Merger Agreement for approval by the DoubleVerify Stockholders, there may not be another opportunity for the DoubleVerify Stockholders to receive a comparably-priced offer with a comparable level of closing certainty. In particular, the Company Board considered the Company’s lower-than-expected Q2 2026 financial results and the fact that such lower-than-expected results could (i) exert significant downward pressure on the Company’s stock price, (ii) risk jeopardizing the ability of Parent and/or Party A to obtain financing in connection with their bids, and (iii) risk jeopardizing the ability of the Company to maintain the per share price set forth in the bids received from both Parent and Party A or cause such bidders to withdraw their bids entirely. For more information, please see the section of this proxy statement captioned “The Merger — Background of the Merger”.

•

Cash Consideration; Certainty of Value. The fact that the Merger Consideration is payable solely in cash, which provides certainty and immediate liquidity and value to each of the DoubleVerify

TABLE OF CONTENTS

Stockholders in respect of their Company Common Stock, enabling the DoubleVerify Stockholders to realize value that has been created at the Company while eliminating long-term business and execution risk and other uncertainties inherent in the Company continuing as a stand-alone company.

•

Counterparty Reputation. The Company Board’s consideration of the business reputation, experience and capabilities of Parent and Parent’s largest shareholders, Elliott and Brookfield, including their strong track records of completing acquisitions.

•

Fairness Opinion of PJT Partners. The financial presentation of PJT Partners and its oral opinion rendered to the Special Committee and the Company Board on August 6, 2026, subsequently confirmed in its written opinion to the Special Committee and the Company Board dated August 6, 2026, that, as of the date thereof and based upon and subject to, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken by PJT Partners in connection with the opinion (which are stated therein), the Merger Consideration to be received by the DoubleVerify Stockholders (other than in respect of the Excluded Shares and any Dissenting Shares) in the Merger was fair to such holders from a financial point of view, as more fully described in the section of this proxy statement captioned “Opinion of PJT Partners”.

•

Likelihood of Closing. The likelihood that the Transactions, including the Merger, would be completed in accordance with the terms and conditions of the Merger Agreement, based on, among other things:

•

the absence of any financing condition in the Merger Agreement;

•

the financial strength of Parent and its ability to fund the aggregate Merger Consideration, including in light of the fact that (i) Elliott committed $200,000,000 of equity financing for the Merger, and (ii) Parent also obtained debt financing for the Merger, which debt financing contains a limited number of conditions to the debt financing;

•

the business reputation and capabilities of Parent;

•

the likelihood and anticipated timing of obtaining all required regulatory clearances in connection with the Merger and the commitments made by Parent to the Company in the Merger Agreement to use reasonable best efforts to obtain regulatory approvals and clearances (for more information, please see the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Regulatory Approvals Required for the Merger”);

•

the fact that the Merger is not subject to the conditionality and execution risk of any required approval by the shareholders of Parent, including Elliott and Brookfield; and

•

the likelihood of satisfying the conditions to the consummation of the Merger, which the Company Board believed were reasonable, customary and limited in number and scope (for more information, please see the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Conditions to Consummation of the Merger”).

•

Financing; No Financing Condition. The Company Board’s consideration of (i) the absence of any financing condition in the Merger Agreement, (ii) Parent’s and Merger Sub’s representations, warranties and covenants contained in the Merger Agreement relating to the delivery by Parent of the Commitment Letters (and the terms and conditions thereof), and (iii) the fact that, under specified circumstances in the event of a willful breach by Parent, the Merger Agreement permits the Company to seek payment of damages from Parent for an amount in excess of the Parent Termination Fee of up to (x) $175,000,000; plus (y) the amount of any recovery costs; plus (z) the amount of any reimbursement and indemnification obligations of Parent required under the debt financing cooperation covenant of the Merger Agreement (for more information, please see the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Termination Fee and Expenses”).

•

Merger Agreement. The terms of the Merger Agreement and the agreements relating thereto, which were reviewed by the Company Board and the Special Committee with the Company’s legal and

TABLE OF CONTENTS

financial advisors, and the fact that such terms were the product of arm’s-length negotiations between the parties, including:

•

the Company’s right, subject to certain conditions and limitations set forth in the Merger Agreement, prior to the receipt of the Required Company Stockholder Approval, to respond to and negotiate unsolicited Acquisition Proposals made after the date of the Merger Agreement and before receipt of the Required Company Stockholder Approval (for more information, please see the sections of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Non-Solicitation” and “Proposal 1: The Merger Agreement Proposal — Adverse Recommendation Changes and Alternative Acquisition Agreements”);

•

the Company Board’s ability to make an Adverse Recommendation Change and to terminate the Merger Agreement in order to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal (in each case as defined in the sections of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Non-Solicitation” and “Proposal 1: The Merger Agreement Proposal — Adverse Recommendation Changes and Alternative Acquisition Agreements”), in each case, subject to certain conditions and limitations set forth in the Merger Agreement, including the Company’s obligation to pay or cause to be paid the Company Termination Fee;

•

the Company Board’s belief that the Company Termination Fee, which is approximately 2.5% of the approximately $2,332,000,000 equity value of the Company implied by the Merger Consideration, is reasonable, within or lower than market averages for such fees payable in comparable transactions, and not preclusive of, or a substantial impediment to, a third party making an Acquisition Proposal (for more information, please see the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Adverse Recommendation Changes and Alternative Acquisition Agreements”);

•

the fact that, in the event the Merger Agreement is terminated in certain circumstances prior to the consummation of the Merger, Parent will be required to pay the Company the Parent Termination Fee subject to and in accordance with the terms of the Merger Agreement (for more information, please see the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Termination Fee and Expenses”);

•

the fact that the consummation of the Merger is subject to the adoption of the Merger Agreement by the DoubleVerify Stockholders, who will have the opportunity to adopt or reject the Merger Agreement;

•

the high degree of certainty that the Merger would close in a timely manner in light of the conditions and other terms set forth in the Merger Agreement, and the requirement that the parties use their respective reasonable best efforts to complete the Transactions, including the Merger, and to obtain all necessary governmental approvals as promptly as reasonably practicable, in each case subject to certain specified limitations;

•

the limited number and nature of the conditions to Parent’s obligation to consummate the Merger;

•

the fact that the Company has sufficient operating flexibility to conduct its business in the ordinary course between execution of the Merger Agreement and the consummation of the Merger;

•

the fact that the initial outside date of May 6, 2027, with an available extension (if necessary) to August 6, 2027, as set forth in the Merger Agreement relating to the failure to obtain required regulatory approvals or clearances, allows for time that the Company Board believed to be sufficient to consummate the Merger;

•

the Company’s right, if the Merger Agreement is validly terminated and prior to such termination there has been a willful breach of the Merger Agreement by Parent or Merger Sub, to seek payment of damages from Parent for an amount in excess of the Parent Termination Fee of up to (x) $175,000,000; plus (y) the amount of any recovery costs; plus (z) the amount of any reimbursement and indemnification obligations of Parent required under the debt financing cooperation covenant of the Merger Agreement (for more information, please see the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Termination Fee and Expenses”); and

The Company Board’s consideration of the availability of appraisal rights under Section 262 of the DGCL to the DoubleVerify Stockholders who do not vote in favor of the adoption of the Merger Agreement and comply with all of the required procedures under Section 262 of the DGCL, which provides such DoubleVerify Stockholders with an opportunity to have the Delaware Court of Chancery determine the fair value of their shares of Company Common Stock, which may be determined to be more than, less than or the same as the amount such stockholders would have received under the Merger Agreement. For additional information, please see the section of this proxy statement captioned “The Merger — Appraisal Rights”.

The Company Board also considered a number of uncertainties, risks and other countervailing factors relating to entering into the Merger Agreement, including, but not limited to (not necessarily in order of relative importance):

•

Closing Certainty. The fact that completion of the Transactions, including the Merger, depends on certain factors outside of the Company’s control, and that there can be no assurance that all of the conditions to the obligations of the Company and Parent to consummate the Merger will be satisfied or, if permissible, waived, including:

the fact that the Closing requires receipt of regulatory approvals and clearances, which may not be received in a timely manner or at all;

the fact that there can be no assurances that the DoubleVerify Stockholders will adopt the Merger Agreement;

the possibility of the occurrence of a Material Adverse Effect, the non-occurrence of which is a condition to Parent’s and Merger Sub’s obligation to consummate the Merger; and

the fact that the Company’s right to damages in the event of a willful breach of the Merger Agreement by Parent or Merger Sub is capped at an amount equal to (x) $175,000,000; plus (y) the amount of any recovery costs; plus (z) the amount of any reimbursement and indemnification obligations of Parent required under the debt financing cooperation covenant of the Merger Agreement (for more information, please see the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Termination Fee and Expenses”).

•

Participation in Future Gains. The fact that, following the completion of the Merger, the Company will no longer exist as a stand-alone publicly-traded company and that the Company’s existing stockholders will not be able to participate in any future earnings or growth of the Company, or in any future appreciation in value of shares of the Company Common Stock.

•

Outside Date. The fact that the potential outside Date is as late as August 6, 2027 (if extended) and the DoubleVerify Stockholders could be asked to vote on the proposal to adopt the Merger Agreement well in advance of the Closing, after which, if the Required Company Stockholder Approval is received, the Company Board would no longer have the ability to consider and respond to competing Acquisition Proposals or terminate the Merger Agreement to accept a Superior Proposal.

•

Impact of Merger Announcement on the Company. The risk that disruptions from the Merger, or the failure of the Merger to close in a timely manner, could (i) harm the Company’s business, including current plans and operations and relationships with the Company’s customers, suppliers, business partners and other third parties, including during the pendency of the Merger, (ii) harm the ability of the Company to retain and hire key personnel and divert employee attention, including during the pendency of the Merger, (iii) affect the Company’s ability to meet internal or published projections, forecasts or revenue or earnings predictions, and (iv) result in the initiation of litigation by certain parties. The Company Board also considered the potential adverse reactions or changes to business relationships, including those with clients, resulting from the announcement or completion of the Merger and that potential business uncertainty, including changes to existing business relationships, during the pendency of the Merger could affect the Company’s financial performance.

TABLE OF CONTENTS

•

Risks Associated with a Failure to Consummate the Merger. The fact that, if the Merger is not completed, (i) the Company will have incurred significant risk, transaction expenses and opportunity costs, including the possibility of disruption to its operations, diversion of management and employee attention, employee attrition and a potentially negative effect on its business and relationships with clients, (ii) depending on the circumstances that caused the Merger not to be completed, it is likely that the trading price of the shares will decline, potentially significantly, and (iii) the market’s perception of the Company’s prospects could be adversely affected.

•

Restrictions on the Operation of the Company’s Business. The fact that, although the Company will continue to exercise control over its operations prior to the Closing, the Merger Agreement prohibits the Company from taking a number of actions relating to the conduct of its business prior to the Closing without the prior written consent of Parent, which may delay or prevent the Company from undertaking certain business opportunities that may arise during the pendency of the Merger, regardless of whether the Merger is completed.

•

Company Termination Fee. The requirement that the Company pay Parent the Company Termination Fee of $60,000,000 following termination of the Merger Agreement in certain circumstances set forth in the Merger Agreement, including if the Company terminates the Merger Agreement in order to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal or if Parent terminates the Merger Agreement following an Adverse Recommendation Change. For more information, please see the section of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Adverse Recommendation Changes and Alternative Acquisition Agreements”.

•

Tax Treatment. The fact that any gains arising from the receipt of the Merger Consideration in an all-cash transaction would generally be taxable to the DoubleVerify Stockholders that are U.S. persons for U.S. federal income tax purposes.

•

Non-Solicit. The fact that, subject to and in accordance with the terms of the Merger Agreement, the Company and its representatives are prohibited from soliciting any Acquisition Proposals until the earlier of the Effective Time and the termination of the Merger Agreement in accordance with its terms (for more information, please see the sections of this proxy statement captioned “Proposal 1: The Merger Agreement Proposal — Non-Solicitation” and “Proposal 1: The Merger Agreement Proposal — Adverse Recommendation Changes and Alternative Acquisition Agreements”).

•

Fees, Costs, and Expenses. The significant costs involved in connection with entering into the Merger Agreement and consummating the Merger (many of which are payable whether or not the Merger is consummated) and the substantial time commitment and effort by the members of the Company’s management team required to consummate the Merger, which may disrupt the Company’s business operations and have a negative effect on its financial results.

•

Effects of Termination. The possibility that, as a result of the termination of the Merger Agreement, possible future acquirers may consider the Company to be an unattractive acquisition candidate.

•

Stockholder Litigation. The risk of litigation arising from the DoubleVerify Stockholders in respect of the Merger Agreement or the Transactions, including the Merger.

•

Financing May Not Be Obtained. The possibility that the equity financing contemplated by the Equity Commitment Letter and the Debt Financing contemplated by the Debt Commitment Letter will not be obtained prior to the outside date set forth in the Merger Agreement, the date of expiration or termination of the lenders’ commitments under the Debt Commitment Letter, or obtained at all, resulting in Parent not having sufficient funds to complete the Merger. The Company Board also considered the fact that in the event any portion of the Debt Financing under the Debt Commitment Letter becomes unavailable (including as a result of expiration or termination of any commitments under the Debt Commitment Letter), Parent, after using its reasonable best efforts, may not be able to obtain alternative financing from alternative financing sources acceptable to Parent, on terms containing no new or additional conditions to the consummation.

•

Potential Differing Interests of Directors and Officers. The Company Board considered the risk that certain directors and executive officers may have interests in the Transactions as individuals that are in addition to, or that may be different from, the interests of the DoubleVerify Stockholders. See the

TABLE OF CONTENTS

section entitled “The Merger — Interests of DoubleVerify’s Directors and Executive Officers in the Merger” of this proxy statement.

•

Other Risks. Other risks and uncertainties of the nature identified in the section of this proxy statement captioned “Forward-Looking Statements” and in the Company’s filings with the SEC, including the risks set forth in “Item 1A. Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2026 and subsequent filings the Company has filed or will file with the SEC. For more information, please see the section of this proxy statement captioned “Where You Can Find More Information.”

After taking into account all of the factors set forth above, the Company Board concluded that the risks, uncertainties, restrictions and potentially negative factors associated with the Merger Agreement and the Transactions, including the Merger, were outweighed by the positive factors and potential benefits associated with the Merger Agreement and the Transactions, including the Merger, that supported its determination and recommendation. Accordingly, the Company Board, acting on the unanimous recommendation of the Special Committee, determined that the Merger Agreement, the Merger, and the other Transactions are fair to and in the best interests of the Company and the DoubleVerify Stockholders. The members of the Company Board evaluated the various factors listed above in light of their knowledge of the businesses, financial condition and prospects of the Company and also considered the input of the members of the Company’s management team and advice of the Company’s legal and financial advisors and the unanimous recommendation of the Special Committee.

The foregoing discussion of reasons for the recommendation to adopt the Merger Agreement and approve the Transactions, including the Merger, addresses the principal reasons considered by the Company Board in consideration of its recommendation but is not intended to be exhaustive and may not include all of the factors considered by the Company Board. In view of the wide variety of reasons considered by the Company Board in connection with its evaluation of the Merger Agreement, the Merger, and the Transactions and the complexity of these matters, the Company Board did not find it practicable to, and did not, quantify or otherwise assign relative weights to the specific reasons considered in reaching its determination and recommendation. Rather, in considering the information and reasons described above, individual members of the Company Board each applied his or her own personal business judgment to the process and may have given differing weights to differing factors. The Company Board did not undertake to make any specific determination as to whether any factor, or any particular aspect of any factor, supported or did not support its ultimate determinations. The Company Board based its recommendation on the totality of the information presented, including (i) thorough discussions with, and questioning of, the members of the Company’s management team and the Company’s legal and financial advisors, and (ii) the unanimous recommendation of the Special Committee.

When considering the foregoing recommendation of the Company Board that you vote to approve the proposal to adopt the Merger Agreement, the DoubleVerify Stockholders should be aware that some of the Company’s directors and executive officers may have interests in the Transactions, including the Merger, that are different from, or in addition to, the interests of the DoubleVerify Stockholders more generally. The Company Board was aware of and considered these interests, among other matters, to the extent that they existed at the time. For more information, please see the section of this proxy statement captioned “The Merger — Interests of DoubleVerify’s Directors and Executive Officers in the Merger”.

The explanation of the reasons and reasoning set forth above contain forward-looking statements that should be read in conjunction with the section of this proxy statement captioned “Cautionary Note Regarding Forward-Looking Statements”.

Opinion of PJT Partners

PJT Partners was retained by the Special Committee to act as its financial advisor in connection with the Merger and, upon the Special Committee’s request, to render its fairness opinion to the Special Committee and the Company Board in connection therewith. The Special Committee selected PJT Partners to act as its financial advisor based on PJT Partners’ qualifications, expertise and reputation, its knowledge of the Company’s industry and its knowledge and understanding of the business and affairs of the Company. At a

meeting of the Special Committee on August 6, 2026, PJT Partners rendered its oral opinion, subsequently confirmed in its written opinion dated August 6, 2026, to the Special Committee and the Company Board that, as of the date thereof and based upon and subject to, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken by PJT Partners in connection with the opinion (which are stated in its written opinion), the Merger Consideration to be received by the holders of shares of Company Common Stock (other than the Excluded Shares and any Dissenting Shares) in the Merger was fair to such holders from a financial point of view.

The full text of PJT Partners’ written opinion delivered to the Special Committee and the Company Board, dated August 6, 2026, is attached as Annex B and incorporated into this proxy statement by reference in its entirety. PJT Partners’ written opinion has been provided by PJT Partners at the request of the Special Committee and is subject to, among other things, the assumptions made, procedures followed, matters considered, and qualifications and limitations on the review undertaken by PJT Partners in connection with the opinion (which are stated therein). You are encouraged to read the opinion carefully in its entirety. PJT Partners provided its opinion to the Special Committee and the Company Board, in their respective capacities as such, in connection with and for purposes of their evaluation of the Merger only and PJT Partners’ opinion does not constitute a recommendation as to any action the Special Committee or the Company Board should take with respect to the Merger or how any holder of Company Common Stock should vote or act with respect to the Merger or any other matter. The following is a summary of PJT Partners’ opinion and the methodology that PJT Partners used to render its opinion. This summary of the PJT Partners opinion contained in this proxy statement is qualified in its entirety by reference to the full text of PJT Partners’ written opinion.

In arriving at its opinion, PJT Partners, among other things:

In preparing its opinion, with the consent of the Special Committee, PJT Partners relied upon and assumed the accuracy and completeness of the foregoing information and all other information discussed with or reviewed by PJT Partners, without independent verification thereof. PJT Partners assumed, with the consent of the Special Committee, that the Projections and the assumptions underlying the Projections, and all other financial analyses, estimates and forecasts provided to PJT Partners by the Company’s management, were reasonably prepared in accordance with industry practice and represented Company management’s best currently available estimates and judgments as to the business and operations and future financial performance of the Company. PJT Partners assumed no responsibility for and expressed no opinion as to the Projections, the assumptions upon which they were based or any other financial analyses, estimates and forecasts provided

TABLE OF CONTENTS

to PJT Partners by the Company’s management. PJT Partners also assumed that there were no material changes in the assets, financial condition, results of operations, business or prospects of the Company since the respective dates of the last financial statements made available to PJT Partners. PJT Partners relied, with the consent of the Special Committee, on Company management’s representations and/or projections regarding taxable income, standalone net operating loss utilization and other tax attributes of the Company. PJT Partners further relied, with the consent of the Special Committee, upon the assurances of the Company’s management that they were not aware of any facts that would make the information, representations and projections provided by them inaccurate, incomplete or misleading.

PJT Partners was not asked to undertake, and did not undertake, an independent verification of any information provided to or reviewed by PJT Partners, nor was it furnished with any such verification and PJT Partners did not assume any responsibility or liability for the accuracy or completeness thereof. PJT Partners did not conduct, nor was it asked to conduct, a physical inspection of any of the properties or assets of the Company or Nielsen. At the Special Committee’s direction, PJT Partners did not conduct, nor did PJT Partners assume any responsibility for conducting, any independent evaluation or appraisal of the assets or the liabilities (contingent, derivative, off-balance sheet, or otherwise) of the Company, nor was it furnished with any such evaluations or appraisals, nor did it evaluate the solvency or fair value of the Company under any applicable laws.

PJT Partners also assumed, with the consent of the Special Committee, that the final executed form of the Merger Agreement would not differ in any material respects from the draft reviewed by PJT Partners and the consummation of the Merger would be effected in accordance with the terms and conditions of the Merger Agreement, without waiver, modification or amendment of any material term, condition or agreement, and that, in the course of obtaining the necessary regulatory or third party consents and approvals (contractual or otherwise) for the Merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on the Company or Parent or the contemplated benefits of the Merger. PJT Partners also assumed that the representations and warranties made by the Company, Parent and Merger Sub in the Merger Agreement were and would be true and correct in all respects material to its analysis. PJT Partners did not express any opinion as to any tax or other consequences that might result from the Merger, nor did its opinion address any legal, tax, regulatory or accounting matters, as to which PJT Partners understood that the Company obtained such advice as it deemed necessary from qualified professionals. PJT Partners is not a legal, tax or regulatory advisor and relied upon, without independent verification, the assessment of the Company and its legal, tax and regulatory advisors with respect to such matters. PJT Partners did not express any opinion as to the relative fairness of the Merger Consideration to be received by any one holder of shares of Company Common Stock as compared to any other holder of shares of Company Common Stock.

PJT Partners did not consider the relative merits of the Merger as compared to any other business plan or opportunity that might be available to the Company or the effect of any other arrangement in which the Company might engage, and PJT Partners’ opinion did not address the underlying decision by the Company to engage in the Merger. PJT Partners’ opinion was limited to the fairness as of the date of the opinion, from a financial point of view, to the holders of shares of Company Common Stock of the Merger Consideration to be received by such holders in the Merger, and PJT Partners’ opinion did not address any other aspect or implication of the Merger, the Merger Agreement, or any other agreement or understanding entered into in connection with the Merger or otherwise. PJT Partners further expressed no opinion or view as to the fairness of the Merger to the holders of any other class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Merger. PJT Partners also expressed no opinion as to the fairness of the amount or nature of the compensation to any of the Company’s officers, directors or employees, or any class of such persons, relative to the Merger Consideration to be received by the holders of shares of Company Common Stock or otherwise.

PJT Partners’ opinion was necessarily based upon economic, market, monetary, regulatory and other conditions as they existed and could be evaluated, and the information made available to PJT Partners, as of the date of the opinion. PJT Partners assumed no responsibility for updating or revising its opinion based on circumstances or events occurring after the date of its opinion. PJT Partners expressed no opinion as to the prices or trading ranges at which the shares of Company Common Stock will trade at any time, as to the potential effects of volatility in the credit, financial and stock markets on the Company or the Merger or as to the impact of the Merger on the solvency or viability of the Company or the ability of the Company to pay its obligations when they come due.

TABLE OF CONTENTS

The issuance of PJT Partners’ opinion was approved by a fairness committee of PJT Partners in accordance with established procedures. PJT Partners’ advisory services and opinion were provided to the Special Committee and the Company Board, in their respective capacities as such, in connection with and for the purposes of their evaluation of the Merger only and the opinion does not constitute a recommendation as to any action the Special Committee or the Company Board should take with respect to the Merger or any aspect thereof. PJT Partners’ opinion does not constitute a recommendation to any holder of shares of Company Common Stock as to how any DoubleVerify Stockholder should vote or act with respect to the Merger or any other matter.

Summary of Financial Analyses

In connection with rendering its opinion, PJT Partners performed certain financial, comparative and other analyses as summarized below. In arriving at its opinion, PJT Partners did not ascribe a specific range of values to the shares of Company Common Stock but rather made its determination as to fairness, from a financial point of view, to the holders of the Company Common Stock of the Merger Consideration to be received by such holders pursuant to the Merger Agreement on the basis of various financial and comparative analyses. The preparation of a fairness opinion is a complex process and involves various determinations as to the most appropriate and relevant methods of financial and comparative analyses and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to summary description.

In arriving at its opinion, PJT Partners did not attribute any particular weight to any single analysis or factor considered by it but rather made qualitative judgments as to the significance and relevance of each analysis and factor relative to all other analyses and factors performed and considered by it and in the context of the circumstances of the Merger. Accordingly, PJT Partners believes that its analyses must be considered as a whole, as considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion.

The following is a summary of the material financial analyses used by PJT Partners in preparing its opinion to the Special Committee and the Company Board. Certain financial analyses summarized below include information presented in tabular format. In order to fully understand the financial analyses used by PJT Partners, the tables must be read together with the text of each summary, as the tables alone do not constitute a complete description of the financial analyses. In performing its analyses, PJT Partners made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of the Company or any other parties to the Merger. None of the Company, PJT Partners, or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth below. In addition, analyses relating to the value of businesses do not purport to be appraisals or reflect the prices at which the businesses may actually be sold. The financial analyses summarized below were based on the Projections and other financial information prepared and furnished to PJT Partners by or on behalf of the Company’s management, and used at the direction of the Company’s management and approved for PJT Partners’ use by the Special Committee. The following summary does not purport to be a complete description of the financial analyses performed by PJT Partners. The following quantitative information, to the extent that it is based on market data, is based on market data as it existed, for the Company, as of the closing trading price on August 5, 2026 (which represented the last trading day for Company Common Stock prior to the date of PJT Partners’ opinion), and is not necessarily indicative of current or future market conditions. Fully diluted share numbers for the Company used below were provided by, and used at the direction of, the Company’s management.

Selected Comparable Company Analysis

PJT Partners reviewed and compared specific financial, operating and public trading data relating to the Company with selected publicly traded advertising technology companies that PJT Partners deemed comparable to the Company. The selected comparable companies (which are referred to collectively as the “Company Peers”) were The Trade Desk, Inc., Magnite, Inc., Taboola.com Ltd., Criteo S.A., Viant Technology Inc. and PubMatic, Inc. PJT Partners reviewed and compared such data in order to assess how

TABLE OF CONTENTS

the public market values shares of similar publicly traded companies and to provide a range of relative implied equity values per share of Company Common Stock on a standalone basis, in each case by reference to these Company Peers.

As part of its selected comparable company analysis, PJT Partners calculated and analyzed certain ratios and multiples, including: total enterprise value (calculated as the equity value based on fully diluted shares outstanding using the treasury stock method, plus debt/debt-like items and less cash and cash equivalents, after giving effect to certain adjustments for non-controlling interests and equity investments) (“TEV”) as a multiple of (1) calendar year 2027E adjusted EBITDA before stock-based compensation (“Adj. EBITDA (Pre-SBC)”) and (2) calendar year 2027E adjusted EBITDA after stock-based compensation (“Adj. EBITDA (Post-SBC)”). All of these calculations were performed and based on publicly available financial data, market data (including share prices) as of the close of trading on August 5, 2026 and consensus estimates derived from sell-side research. The results of this selected comparable company analysis are summarized below:

Company
Peers Low

Company
Peers High

TEV/2027E Adj. EBITDA (Pre-SBC)

1.7x

10.9x

TEV/2027E Adj. EBITDA (Post-SBC)

2.3x

18.9x

PJT Partners, based on its professional judgment, selected the Company Peers because PJT Partners believed their businesses and operating profiles are reasonably similar to that of the Company. However, because of the inherent differences between the businesses, operations and prospects of the Company and those of the Company Peers, PJT Partners believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the selected comparable company analysis. Accordingly, PJT Partners also made qualitative judgments concerning differences between the businesses, financial and operating characteristics and prospects of the Company and the Company Peers that could affect the public trading values of each in order to provide a context in which to consider the results of the quantitative analysis. These qualitative judgments related primarily to the differing sizes, growth prospects, profitability levels and degree of operational risk between the Company and the Company Peers.

Accordingly, PJT Partners selected (1) a TEV to Adj. EBITDA (Pre-SBC) multiple range of 5.0x to 8.0x for calendar year 2027E and (2) a TEV to Adj. EBITDA (Post-SBC) multiple range of 7.5x to 10.5x for calendar year 2027E, in each case for the Company on a standalone basis. PJT Partners then applied these ranges to the Company’s calendar year 2027E Adj. EBITDA (Pre-SBC) and calendar year 2027E Adj. EBITDA (Post-SBC) based on the Projections, to calculate a range of implied prices per share of Company Common Stock on a standalone basis based on the fully diluted number of shares of Company Common Stock as of June 30, 2026. The following summarizes the results of these calculations:

	Implied prices per share of Company Common Stock
TEV/2027E Adj. EBITDA (Pre-SBC)		$	10.62 – $16.22
TEV/2027E Adj. EBITDA (Post-SBC)		$	10.77 – $14.56

Selected Precedent Transaction Analysis

PJT Partners reviewed, to the extent publicly available, and analyzed the valuation and financial metrics relating to the following six (6) selected transactions since 2017 involving companies in the advertising technology industry, which PJT Partners, in its professional judgment, considered generally relevant for comparative purposes:

Announcement Date	Target	Acquiror
May 17, 2026	LiveRamp Holdings, Inc.	Publicis Groupe S.A.
September 24, 2025	Integral Ad Science Holding Corp.	Novacap Management Inc.
August 1, 2024	TEADS	Outbrain Inc.
March 29, 2022	Nielsen Holdings plc	Evergreen Coast Capital Corporation (Brookfield Business Partners L.P. &

TABLE OF CONTENTS

Announcement Date	Target	Acquiror
		Elliott Investment Management L.P.)
November 1, 2020	Nielsen Global Connect	Advent International Corporation
September 5, 2017	YuMe, Inc.	RhythmOne plc

For each precedent transaction, PJT Partners reviewed the TEV of the target company in the transaction as a multiple of (a) the target company’s Adj. EBITDA (Pre-SBC) for the twelve (12) months ended prior to announcement of the transaction (which is referred to as “LTM Adj. EBITDA (Pre-SBC)”) and (b) the target company’s Adj. EBITDA (Post-SBC) for such period (which is referred to as “LTM Adj. EBITDA (Post-SBC)”), as summarized in the following:

Low

High

TEV/LTM Adj. EBITDA (Pre-SBC)

5.9x

11.4x

TEV/LTM Adj. EBITDA (Post-SBC)

7.0x

20.7x

Estimated financial data of the selected transactions were based on publicly available information at the time of announcement of the relevant transaction.

The reasons for and the circumstances surrounding each of the selected precedent transactions analyzed were diverse and there are inherent differences in the business, operations, financial conditions and prospects of the Company and the companies included in the selected precedent transaction analysis, which PJT Partners discussed with the Special Committee. In addition, certain of the selected precedent transactions involved the purchase and sale of certain assets and businesses rather than transactions involving whole companies, and the selected precedent transactions occurred during periods in which financial, economic and market conditions were different from those in existence as of the date of PJT Partners’ opinion. Accordingly, PJT Partners believed, and discussed with the Special Committee, that a purely quantitative selected precedent transaction analysis would not be particularly meaningful in the context of considering the Merger. PJT Partners therefore made qualitative judgments concerning the differences between the characteristics of the selected precedent transactions and the Merger that would affect the acquisition values of the selected target companies and the Company. After reviewing the above analyses, PJT Partners selected a TEV to LTM Adj. EBITDA (Pre-SBC) range of 7.5x to 10.0x and a TEV to LTM Adj. EBITDA (Post-SBC) range of 12.0x to 15.0x for the Company on a standalone basis and applied these ranges to the Company’s LTM Adj. EBITDA (Pre-SBC) and LTM Adj. EBITDA (Post-SBC) based on the Projections (in each case for the twelve (12) months ended June 30, 2026), to calculate a range of implied prices per share of Company Common Stock on a standalone basis. The following summarizes the results of these calculations:

	Implied prices per share of Company Common Stock
TEV/LTM Adj. EBITDA (Pre-SBC)		$	12.65 – $16.39
TEV/LTM Adj. EBITDA (Post-SBC)		$	12.40 – $15.15

Discounted Cash Flow Analysis

In order to estimate the present value of Company Common Stock, PJT Partners performed a discounted cash flow analysis of the Company. A discounted cash flow analysis is a traditional valuation methodology used to derive a valuation of an asset by calculating the “present value” of estimated future cash flows generated by the asset. “Present value” refers to the current value of future cash flows or amounts and is obtained by discounting those future cash flows or amounts by a discount rate that takes into account macroeconomic assumptions and estimates of risk, the opportunity cost of capital, expected returns and other appropriate factors.

To calculate the estimated enterprise value of the Company using the discounted cash flow method, PJT Partners added (a) the Company’s projected after-tax unlevered free cash flows for the period from July 1, 2026 through fiscal year end 2034E based on the Projections (which are referred to in this section titled “Opinion of PJT Partners” as the “Company Standalone 8.5-Year DCF Analysis”) to (b) ranges of “terminal values” of the Company as of December 31, 2034, and discounted such amounts to their present value as of

TABLE OF CONTENTS

June 30, 2026 using a range of selected discount rates. The after-tax unlevered free cash flows were calculated by taking Adj. EBITDA (Post-SBC), subtracting finance lease cash expense and capital expenditures, adjusting for changes in net working capital and subtracting unlevered cash taxes. The residual value of the Company at the end of the projection period, or “terminal value,” was estimated by applying a range of perpetuity growth rates of 2.5% to 4.5% to the Company’s normalized terminal period unlevered free cash flow from the Projections. The range of after-tax discount rates of 12.0% to 13.5% was selected based on PJT Partners’ analysis of the weighted average cost of capital of the Company. PJT Partners then calculated a range of implied equity values per share of Company Common Stock by adding the Company’s net cash as of June 30, 2026 to the estimated enterprise value derived using the discounted cash flow method and dividing such amount by the fully diluted number of shares of Company Common Stock as of June 30, 2026. The following summarizes the results of these calculations:

Company Standalone 8.5-Year DCF Analysis			Implied equity values per share of Company Common Stock
Projections				$	11.64 – $15.47

Other Information

PJT Partners also observed the additional factors described below, which were not considered part of its financial analyses in connection with rendering its opinion, but were referenced solely for informational purposes:

•

a discounted cash flow analysis of the Company in order to estimate the present value of the Company Common Stock as of June 30, 2026 based on a consensus broker case of Adj. EBITDA (Post-SBC) for the period from July 1, 2026 through fiscal year end 2034E, using the same range of perpetuity growth rates of 2.5% to 4.5% and discount rates of 12.0% to 13.5% as noted above. This analysis resulted in a range of implied equity values per share of Company Common Stock of $9.67 to $12.75;

•

General

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying PJT Partners’ opinion. In arriving at its fairness determination, PJT Partners considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, PJT Partners made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company or transaction used in the above-described analyses as a comparison is directly comparable to the Company or the Merger. The terms of the Merger Agreement, including the Merger Consideration, were determined through arm’s-length negotiations between the Company and Parent, rather than PJT Partners, and were approved by the Company Board, acting on the unanimous recommendation of the Special Committee. The decision to enter into the Merger Agreement was solely that of the Company and Parent.

PJT Partners prepared these analyses for purposes of providing its opinion to the Special Committee and the Company Board as to the fairness, from a financial point of view, as of the date of the written opinion of PJT Partners, of the Merger Consideration to be received by the holders of shares of Company Common Stock pursuant to the Merger Agreement. PJT Partners did not recommend any specific consideration to the

TABLE OF CONTENTS

Company, the Special Committee or the Company Board, or that any specific amount or type of consideration constituted the only appropriate consideration for the Merger. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon forecasts of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, none of the Company, Parent, PJT Partners or any other person assumes responsibility if future results are materially different from those forecasted.

PJT Partners is an internationally recognized investment banking firm and, as part of its and its affiliates’ investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, investments for passive and control purposes, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for estate, corporate and other purposes. As a leading global M&A, capital raising, restructuring and liability management, and governance and shareholder practices advisor, PJT Partners and its affiliates undertake significant client coverage efforts and have advised and/or discussed potential strategic transactions with a number of participants in the Company’s sector. The Special Committee selected PJT Partners to act as its financial advisor because of its qualifications, reputation and experience in the valuation of businesses and securities in connection with mergers and acquisitions generally and in the advertising technology industry specifically.

PJT Partners is acting as financial advisor to the Special Committee in connection with the Merger. As compensation for its services in connection with the Merger, PJT Partners is entitled to receive from the Company an aggregate fee of approximately $23 million, $2 million of which became payable upon the delivery of PJT Partners’ opinion to the Special Committee (regardless of the conclusion reached therein) and the remainder of which is contingent and payable upon the consummation of the Merger. The Company has agreed to reimburse PJT Partners for out-of-pocket expenses and to indemnify PJT Partners for certain liabilities arising out of the performance of such services (including the rendering of PJT Partners’ opinion).

In the ordinary course of PJT Partners and its affiliates’ businesses, PJT Partners and its affiliates may provide investment banking and other financial services to the Company, Nielsen or their respective affiliates and may receive compensation for the rendering of these services. During the two years preceding the date of its opinion, PJT Partners and certain of its affiliates are advising or have advised: (i) through its fund advisory business, Providence Equity Partners L.L.C. in connection with a potential transaction unrelated to the Company or the Merger, for which PJT Partners has not received any fees, but may in the future receive fees anticipated to be significantly less than the total fees contemplated to be received by PJT Partners in connection with the Merger (such total fees, the “Transaction Fee”), (ii) through its restructuring and special situations group, (A) Elliott Management Corporation (together with its affiliates and portfolio companies, the “Elliott Entities”, and each, an “Elliott Entity”) in connection with various restructuring matters unrelated to the Company or the Merger, for which PJT Partners has received fees of less than $20 million in the aggregate, and may in the future receive additional fees anticipated to be less, in the aggregate, than the Transaction Fee, paid by each such Elliott Entity and (B) Brookfield Corporation (together with its affiliates and portfolio companies, the “Brookfield Entities”, and each, a “Brookfield Entity”) in connection with various restructuring matters unrelated to the Company or the Merger, for which PJT Partners has received fees of less than $35 million in the aggregate, and may in the future receive additional fees anticipated to be less, in the aggregate, than the Transaction Fee, paid by each such Brookfield Entity, (iii) through its restructuring and special situations group, creditor groups which have included the Elliott Entities or the Brookfield Entities in connection with various restructuring situations of third parties unrelated to the Company or the Merger, for which PJT Partners has received fees and may in the future receive additional fees paid by such third parties, (iv) through its fund advisory business, a Brookfield Entity in connection with a transaction unrelated to the Company or the Merger which ultimately did not proceed and for which PJT Partners received no fees, (v) a Brookfield Entity in connection with a transaction unrelated to the Company or the Merger, for which PJT Partners has received fees of approximately $10 million, and may in the future receive additional fees anticipated to be less, in the aggregate, than the Transaction Fee, (vi) an entity in which a Brookfield Entity maintains a significant interest in connection with shareholder advisory services unrelated to the Company or the Merger, for which PJT Partners has received fees significantly less, in the aggregate, than the Transaction Fee, and may in the future receive additional fees anticipated to be, in the aggregate, less than, or up to, the

TABLE OF CONTENTS

Transaction Fee, depending on various factors, (vii) a Brookfield Entity in connection with a potential financing transaction unrelated to the Company or the Merger, for which PJT Partners has not yet received fees, but may in the future receive fees anticipated to be significantly less, in the aggregate, than the Transaction Fee, and (viii) a Brookfield Entity in connection with a capital raise and acquisition unrelated to the Company or the Merger, for which PJT Partners received fees significantly less, in the aggregate, than the Transaction Fee. PJT Partners and its affiliates have not advised, or received fees from, the Company or Nielsen during this period.

Certain Company Financial Forecasts

DoubleVerify does not generally as a matter of course publish or make public its business plans and strategies or make external disclosures about its anticipated financial position or results of operations, other than providing, from time to time, estimates of certain expected financial results and operational metrics in its regular annual and quarterly earnings press releases and other investor materials.

However, (i) DoubleVerify is including in this proxy statement a summary of certain non-public, unaudited, prospective financial information of DoubleVerify on a standalone basis for fiscal years ending December 31, 2026 through December 31, 2030, and (ii) Company management also prepared and provided growth rates, margins, and other key assumptions to PJT Partners, which PJT Partners was directed to use for fiscal years ending December 2031 through December 2034, in each case, without giving effect to the Merger (the “Projections”), and in each case, prepared by members of the Company’s management team, at the direction of the Company Board and the Special Committee, in connection with the Transactions and approved for PJT Partners’ use by the management of the Company, who directed PJT Partners to use and rely upon the Projections in connection with its financial analyses and opinion.

The Projections as to future performance, revenues, earnings or other results, particularly for extended time periods further in the future, are inherently uncertain and unpredictable, including due to the subjectivity of the underlying assumptions and estimates and the likelihood that such underlying assumptions and estimates will not be realized. As a result, DoubleVerify does not endorse projections or other unaudited prospective financial information as a reliable indication of future results.

In connection with the Company Board’s and the Special Committee’s evaluation of a potential transaction, the members of the Company’s management team, at the request of the Company Board, provided PJT Partners with, and approved and directed for PJT Partners’ use, the Projections. The Projections were prepared by the Company’s management team and made available to the Company Board and the Special Committee in connection with their consideration and evaluation of the Merger, approved by the Company Board and the Special Committee and provided to PJT Partners by the Company’s management team, who directed PJT Partners to use and rely upon the Projections in connection with its financial analyses and opinion.

DoubleVerify is including a summary of the Projections in this proxy statement in order to provide the DoubleVerify Stockholders with access to the latest projections that were made available to (i) the Company Board and the Special Committee in connection with their evaluation of the Merger; and (ii) the Special Committee’s financial advisor, PJT Partners, and which were approved by the Company Board and the Special Committee for PJT Partners to use and which PJT Partners were directed to use and rely upon, in connection with its financial analyses and opinion.

The Projections are not included in this proxy statement in order to influence any DoubleVerify stockholder’s decision to vote with respect to the adoption of the Merger Agreement or for any other purpose. The inclusion of the Projections and this summary should not be regarded as an indication that DoubleVerify, Parent or their respective managements, directors, officers, employees, advisors or any other recipient of this information or a summary thereof considered, or now considers, it to be an assurance of the achievement of future results or necessarily predictive of actual future results, and the Projections should not be relied on as such. This information is not fact and readers of this proxy statement are cautioned not to place undue reliance on the Projections. For addition information on risks and other uncertainties associated with the Projections, please see the section titled “Cautionary Note Regarding Forward-Looking Statements” beginning on page 26.

TABLE OF CONTENTS

The following table summarizes certain non-public, unaudited, prospective financial information contained in the Projections:

($ in millions)	2026E			2027E			2028E			2029E			2030E

(1)

“Adjusted EBITDA” is a non-GAAP measure that represents DoubleVerify’s net income (loss) adjusted to exclude, as applicable, depreciation and amortization, stock-based compensation, interest expense, income tax expense, mergers and acquisitions and restructuring costs, offering and secondary offering costs, other costs and other income.

(2)

“Unlevered Free Cash Flow” is a non-GAAP measure that represents DoubleVerify’s Adjusted EBITDA (Post-SBC) less finance lease cash expenses, capital expenditures, changes in net working capital, and unlevered cash taxes.

(3)

Unlevered Free Cash Flow for 2026E is the expected Unlevered Free Cash Flow for the third and fourth quarters of fiscal year 2026.

Additional Information About the Projections

The inclusion of the Projections in this proxy statement should not be regarded as an indication that DoubleVerify, or any of its affiliates, advisors or representatives, have considered the Projections to be predictive of actual future events, and the Projections should not be relied upon as such. DoubleVerify’s internal financial forecasts upon which the Projections were based are subjective in many respects. The Projections did not take into account any changes or expenses attributable solely to the Transactions nor did they reflect any effects of the Merger or effects of the failure of the Merger to be consummated.

Although presented with numerical specificity, the Projections were based on numerous variables, assumptions and estimates as to future events made by DoubleVerify’s management that DoubleVerify’s management believed were reasonable at the time the Projections were prepared, taking into account the relevant information available to management at the time. Important factors that may affect actual results and cause these internal financial Projections not to be achieved include, but are not limited to, risks and uncertainties relating to the business of DoubleVerify, including, without limitation, (i) that DoubleVerify’s strategic initiatives may (A) incur expenses greater than those projected, and (B) result in increases in revenue with suboptimal margins or that do not occur on the timeline reflected in the Projections or at all, and (ii) industry performance, the accuracy of certain accounting assumptions, changes in actual or projected cash flows, the regulatory and competitive environment, general business and economic conditions (including, without limitation, the risks and uncertainties of an economic downturn) and other risks and factors described in the section titled “Cautionary Note Regarding Forward-Looking Statements” beginning on page 26, as well as additional factors discussed in DoubleVerify’s periodic filings with the SEC, including in its Annual Report on Form 10-K for the year ended December 31, 2025 (which is incorporated by reference herein) and its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2026 (which is incorporated by reference herein). Various assumptions underlying the Projections may not prove to have been, or may no longer be, accurate. The Projections may not be realized, and actual results may be significantly higher or lower than projected in the Projections.

The Projections reflect assumptions as to certain business strategies or plans that are subject to change and are susceptible to multiple interpretations. The Projections do not take into account any circumstances or events occurring after the date they were prepared.

The Projections cover multiple years, and such information by its nature becomes less predictive with each successive year. As a result, the inclusion of the Projections in this proxy statement should not be relied on as necessarily predictive of actual future events and actual results may differ materially (and will differ

TABLE OF CONTENTS

materially if the Merger is completed) from the Projections. For all of these reasons, the Projections, and the assumptions upon which they are based, (1) are not guarantees of future results; (2) are inherently speculative; and (3) are subject to a number of risks and uncertainties. Accordingly, there can be no assurance that the Projections will be realized and actual results will differ, and may differ materially, from those contained in the Projections.

The Projections were prepared solely for internal use and to assist the Company Board and the Special Committee with their consideration and evaluation of the Merger, each of which approved them for PJT Partners to use and which PJT Partners were directed to use and rely upon in connection with its financial analyses and opinion, and although they were prepared on an accounting basis consistent with DoubleVerify’s financial statements, they were not prepared with a view toward public disclosure or toward compliance with published guidelines of the SEC, U.S. generally accepted accounting principles (“GAAP”) or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The Projections included in this proxy statement have been prepared by, and are the responsibility of, DoubleVerify’s management. Neither DoubleVerify’s independent auditor nor any other independent accountant has audited, reviewed, compiled, examined or applied agreed-upon procedures with respect to the Projections, and, accordingly, they do not express an opinion or any other form of assurance with respect thereto. The report of Deloitte & Touche LLP included in DoubleVerify’s most recent Annual Report on Form 10-K (which is incorporated by reference herein) relates to DoubleVerify’s previously issued financial statements. It does not extend to the Projections and should not be read to do so.

Certain of the measures contained in the Projections, including Adj. EBITDA (Pre-SBC), Adj. EBITDA (Post-SBC) and Unlevered Free Cash Flow, are “non-GAAP financial measures,” which are financial performance measures that are not calculated in accordance with GAAP. The non-GAAP financial measures used in the Projections were relied upon by PJT Partners for purposes of its opinion, at the direction of DoubleVerify’s management, with the approval of the Company Board and the Special Committee. The non-GAAP financial measures used in the Projections were also relied upon by the Company Board and the Special Committee in connection with their evaluation of the Merger. The SEC rules which would otherwise require a reconciliation of a non-GAAP financial measure to a GAAP financial measure do not apply to non-GAAP financial measures included in disclosures relating to a proposed business combination such as the Merger if the disclosure is included in a document such as this proxy statement. In addition, reconciliations of non-GAAP financial measures to the most directly comparable GAAP measures were not relied upon by PJT Partners for purposes of performing its financial analysis in connection with rendering its opinion, as described in the section titled “— Opinion of PJT Partners”, nor were they relied upon by the Company Board or the Special Committee in connection with their evaluation of the Merger. Accordingly, DoubleVerify has not provided a reconciliation of the financial measures included in the Projections to the relevant GAAP financial measures. Non-GAAP measures have limitations as analytical tools, and you should not consider these measures in isolation or as substitutes for analysis of our financial results as reported under GAAP. For example, in evaluating Adj. EBITDA (Pre-SBC), Adj. EBITDA (Post-SBC) and other metrics derived from it, you should be aware that in the future DoubleVerify will incur expenses such as those that are the subject of adjustments in deriving Adj. EBITDA (Pre-SBC) and Adj. EBITDA (Post-SBC) and you should not infer from our presentation of Adj. EBITDA (Pre-SBC) and Adj. EBITDA (Post-SBC) that our future results will not be affected by these expenses or any unusual or non-recurring items.

For these reasons, as well as the basis and assumptions on which the Projections were compiled, the inclusion of specific portions of the Projections in this proxy statement should not be regarded as an indication that such Projections will be an accurate prediction of future events, and they should not be relied on as such. None of DoubleVerify nor any of its affiliates, advisors, officers, directors, partners or representatives (including PJT Partners and its affiliates) can give you any assurance that actual results will not differ from these Projections.

Except to the extent required by applicable federal securities laws, none of DoubleVerify nor any of its affiliates, advisors, officers, directors, partners or representatives (including PJT Partners and its affiliates) undertake any obligation to update or otherwise revise or reconcile the Projections or the specific portions presented to reflect circumstances existing after the date the Projections were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions are shown to be in error. Therefore, readers of this proxy statement are cautioned not to place undue, if any, reliance on the specific

TABLE OF CONTENTS

portions of the Projections set forth above. None of DoubleVerify nor any of its affiliates, advisors, officers, directors, partners or representatives (including PJT Partners and its affiliates) intend to make publicly available any update or other revision to these Projections. In addition, none of DoubleVerify nor any of its affiliates, advisors, officers, directors, partners or representatives (including PJT Partners and its affiliates) have made, make or are authorized in the future to make, any representation to any stockholder or other person regarding DoubleVerify’s ultimate performance compared to the information contained in the Projections or that projected results will be achieved, and any statements to the contrary should be disregarded. The Projections should be evaluated, if at all, in conjunction with the historical financial statements and other financial information contained in DoubleVerify’s public filings with the SEC. DoubleVerify has made no representation to Parent or Merger Sub, in the Merger Agreement or otherwise, concerning the Projections.

Interests of DoubleVerify’s Directors and Executive Officers in the Merger

You should be aware that the Company’s directors and executive officers may have certain interests in the Merger that may be different from, or in addition to, the interests of the DoubleVerify Stockholders more generally. The Company Board and the Special Committee were aware of these interests and considered them, among other matters, in evaluating and negotiating the Merger Agreement, approving the Merger Agreement and the Merger, and recommending that the Merger Agreement Proposal be approved by the DoubleVerify Stockholders. These interests are described and quantified in detail in the narrative and tables below.

The Company’s executive officers as of the date hereof and for purposes of this proxy statement are Mark Zagorski (Chief Executive Officer), Nicola Allais (Chief Financial Officer), Steven Mougis (Global Chief Commercial Officer), Andrew Grimmig (Chief Legal Officer) and Julie Eddleman (Former Executive Vice President and Global Commercial Officer). Ms. Eddleman resigned from employment with the Company on December 31, 2025, but continues to provide services to the Company as a consultant, and in accordance with SEC rules, is considered to be a named executive officer for purposes of this proxy statement because she was an executive officer of the Company for whom disclosure was required in the Company’s most recent proxy statement.

The Company’s non-employee directors as of the date hereof and for purposes of this proxy statement are Laura B. Desmond, Lucy Stamell Dobrin, Sundeep Jain, Robert Davis Noell, Rosario Perez, Jennifer Storms, Gary Swidler, Kelli Turner and Scott Wagner.

Certain Assumptions

Except as otherwise specifically noted, for purposes of quantifying the payments and benefits described in this section, the following assumptions were used:

•

The consummation of the Merger occurs on August 31, 2026, which, for purposes of the section of this proxy statement titled, “Interests of DoubleVerify’s Directors and Executive Officers in the Merger,” we refer to as the “assumed closing date”;

•

The consummation of the Merger will constitute a “change in control” under the terms of the applicable plan or agreement;

•

The relevant price of a share of Company Common Stock is $13.60 (which is the Merger Consideration);

•

The calculations in this section do not include amounts to which each director or executive officer was already entitled as of the assumed closing date (other than equity awards that will be canceled in connection with the Merger and for which payments will be made pursuant to the Merger Agreement), and these amounts do not attempt to forecast any additional equity award or compensation grants, issuances, or forfeitures that may occur after the assumed closing date and prior to the consummation of the Merger; and

•

For purposes of the information required by Item 402(t) of Regulation S-K, each named executive officer experiences a qualifying termination (as defined below) on the assumed closing date.

As a result of the foregoing assumptions, which may or may not actually occur or be accurate on the relevant date, including the assumptions described in this section, the actual amounts, if any, to be received by the directors and executive officers may differ materially from the amounts set forth below.

TABLE OF CONTENTS

Treatment of Shares of Company Common Stock

For information regarding beneficial ownership of the shares of Company Common Stock held by each of the Company’s directors and executive officers and all directors and executive officers as a group, see the section titled, “The Special Meeting-Stock Ownership and Interests of Certain Persons.” Each of the Company’s directors and executive officers will be entitled to receive, for each share of Company Common Stock held by such individual, the Merger Consideration in the same manner as other DoubleVerify Stockholders.

Treatment of Company Equity Awards

The Company has granted Company Stock Options, Company RSUs, and Company PSUs. At the Effective Time, the awards will be treated as follows:

•

Each vested, in-the-money Company Stock Option, including awards that vest in connection with the Closing, will be cashed out for its aggregate spread value (based on the excess of the Merger Consideration over the per share exercise price and the number of shares of Company Common Stock underlying such Company Stock Option). Each unvested, in-the-money Company Stock Option will be converted into a Cash Replacement Award equal to its aggregate spread value which will vest and be paid out on the same vesting terms that applied to the corresponding Company Stock Option. All underwater Company Stock Options (whether vested or unvested) will be canceled for no consideration.

•

Each vested Company RSU, including each award that vests in connection with the Closing, will be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such vested Company RSU. Each unvested Company RSU will be converted into a Cash Replacement Award equal to the product of the Merger Consideration and the number of unvested shares of Company Common Stock subject to such Company RSU, which will vest and be paid out on the same vesting terms that applied to the corresponding Company RSU.

•

Each Company PSU as to which the applicable performance-based vesting conditions have been satisfied and that remains subject solely to service-based vesting conditions will, to the extent vested as of immediately prior to the Effective Time, be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such vested Earned Company PSU. Each Earned Company PSU that does not vest in connection with the Closing will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such unvested Earned Company PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Earned Company PSU. Each Company PSU that is not an Earned Company PSU will be converted into a Converted PSU with respect to the number of shares of Company Common Stock determined by the Compensation Committee based on performance through the Effective Time, in accordance with the underlying award agreement. Each Converted PSU will be converted into the right to receive a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such Converted PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Converted PSU.

•

All Cash Replacement Awards will accelerate upon a severance-eligible employment termination within twelve months following the Effective Time, or the holder’s death.

Quantification of Awards

The following table sets forth, for each executive officer and director, the number of Company Stock Options, Company RSUs, and Company PSUs (based on an estimate of actual performance for all Company PSUs) held as of the assumed closing date. As described in further detail above, vested Company Stock Options, vested Company RSUs, and vested Earned Company PSUs will be canceled and converted into the right to receive a cash payment at the Effective Time, and unvested Company RSUs, unvested Earned Company PSUs, and Converted PSUs will be canceled and converted into Cash Replacement Awards that remain subject to their original vesting schedules and are eligible for accelerated vesting upon certain qualifying

terminations of employment following the Closing. The values in the table below have been determined based on the Merger Consideration of $13.60 per share of Company Common Stock. Actual amounts may differ from the amounts set forth below.

(1)

The amounts in this table include previously vested awards to which the holder is entitled regardless of whether the Merger is consummated. The amounts in this table do not reflect any Company equity awards that may be granted between the date hereof and the Effective Time, nor do they represent any forfeitures or vesting events that may occur prior to the Effective Time.

(2)

Amounts in this column include both vested and unvested Company Stock Options, regardless of whether such Company Stock Options are in-the-money.

(3)

Amounts in this column represent the value of the in-the-money Company Stock Options held by each executive officer.

(4)

The Company PSU values in the table above assume vesting based on actual performance as of the assumed closing date used in this proxy statement, which is 100% of target for revenue-based Company PSUs granted in 2026, 69.64% of target for share-price based Company PSUs granted in 2026, and an assumed determination of 0% of target for TSR-based Company PSUs granted in 2025 and 2024. Under the Merger Agreement, the number of shares subject to each Company PSU that is not an Earned Company PSU will be determined by the Compensation Committee in accordance with the applicable award agreement, subject to Parent’s review and reasonable comment. No such determination of actual performance has been made as of the date of this proxy statement, and actual amounts may differ materially.

(5)

Company RSUs are held by Hilltopper LLC, which is wholly owned by Mr. Wagner.

TABLE OF CONTENTS

(6)

Company RSUs are held by OPCR Tree, LLC, which is wholly owned by JKS Group Revocable Family Trust, of which Mr. Jain is trustee and a beneficiary.

(7)

Company RSUs are held by the Laura B. Desmond Revocable Trust, for which Laura B. Desmond is trustee. Includes 23,792 vested Company RSUs, consisting of (i) 9,183 vested Company RSUs that will settle on the earlier of March 2027 and the end of Ms. Desmond’s service as a director (in which case the shares will be delivered in five (5) annual installments commencing in the year of termination), and (ii) 14,609 vested Company RSUs that will settle on the earlier of January 2027 and the end of Ms. Desmond’s service as a director (in which case the shares will be delivered in a lump sum in the year of termination). Ms. Desmond has also deferred settlement of 20,000 unvested Company RSUs that will settle upon the end of her service as a director. These deferral elections affect only the timing of settlement.

(8)

Company RSUs held by Ms. Turner include 9,183 vested Company RSUs, which will settle upon the end of her service as a director, with the shares delivered in five (5) annual installments commencing in the year of termination. Ms. Turner’s deferral election affects only the timing of settlement.

(9)

Company RSUs held by Mr. Zagorski include 131,250 vested Company RSUs, which are fully vested and, pursuant to his deferral election, will settle in a lump sum upon his separation from service. Mr. Zagorski has also deferred settlement of 18,750 unvested Company RSUs. Mr. Zagorski’s deferral election affects only the timing of settlement.

(10)

Ms. Eddleman resigned from employment with the Company, effective December 31, 2025, and subsequently entered into a consulting agreement with the Company, with a term expiring on September 30, 2026. In connection with her separation from employment, Company equity awards with vesting dates beyond December 31, 2026 (the maximum possible term of her consulting agreement at the time of her separation) were canceled. At the Effective Time, Ms. Eddleman’s remaining outstanding Company Stock Options (all of which are underwater based on the Merger Consideration) will be canceled for no consideration, and her remaining unvested Company RSUs and unvested Earned Company PSUs will be converted into Cash Replacement Awards that will continue to vest in accordance with their original vesting schedules through September 30, 2026.

Amendments to Employment Agreements

On August 6, 2026, the Company amended the contractual severance benefits for certain employees of the Company, including Messrs. Zagorski, Allais, Mougis, and Grimmig, in connection with a future qualifying termination of employment. If a qualifying termination of employment occurs within the three (3) months prior to, or the twelve (12) months following, a Change in Control (as defined in the Company’s 2021 Omnibus Equity Incentive Plan), such as the Merger (such period, the “CIC Period”), the employee’s severance benefits are enhanced when compared to the severance benefits payable in connection with a qualifying termination outside of the CIC Period. For the Company’s named executive officers, the severance benefits for a qualifying termination of employment outside of a CIC Period are (i) six (6) to eighteen (18) months of base salary continuation, (ii) a pro-rated bonus for the year of termination based on actual performance, and (iii) COBRA benefits at the active-employee rate for six (6) to twenty-four (24) months, and for a qualifying termination of employment within a CIC Period such benefits are enhanced so that the named executive officer receives, in addition to base salary continuation (which for Mr. Zagorski is increased to twenty-four (24) months), (a) payment of the executive’s full target bonus for the year of termination (in lieu of a pro-rated bonus), (b) Company payment of the full premium for COBRA continuation for twelve (12) to twenty-four (24) months (in lieu of continuation at the active-employee rate), and (c) double-trigger equity protection for any equity awards then held by the executive, including Cash Replacement Awards. The amendments also provide a customary “best net after tax” cutback provision should amounts payable to any such executive potentially be subject to any excise taxes imposed under Section 4999 of the Code, and no eligible employee (including any named executive officer) is entitled to any gross-up payment to offset any excise taxes that may be imposed under Code Section 4999. Although the amendments cover qualifying terminations occurring within the three (3) months prior to a Change in Control, accelerated vesting of Cash Replacement Awards under the Merger Agreement applies only to terminations occurring within the twelve-month period following the Closing. Because Ms. Eddleman resigned from employment, she will not have a qualifying termination, and her consulting agreement with the Company does not provide any severance benefits upon the termination of her service with the Company.

Transaction Bonuses

Additionally, on August 6, 2026, the Company Board approved the implementation of a transaction bonus program with an aggregate pool of $3.5 million. Messrs. Zagorski, Allais, Mougis, and Grimmig may be awarded transaction bonuses pursuant to this program between the signing of the Merger Agreement and the Effective Time. No transaction bonuses have been awarded to any named executive officer as of the date of this proxy statement; accordingly, no amounts in respect of this program are reflected in the golden parachute table. Any such awards would constitute single-trigger compensation payable in connection with the consummation of the Merger.

Excise Taxes Under Section 4999 of the Code

No arrangements with any of the Company’s executive officers provide for any gross-up with respect to any excise tax imposed by Section 4999 of the Code. However, if any payments to Mr. Zagorski, Mr. Allais, Mr. Mougis, or Mr. Grimmig in connection with the consummation of the Merger would constitute a “parachute payment” within the meaning of Section 280G of the Code that could result in an excise tax under Section 4999 of the Code or the denial of deduction under Section 280G of the Code, such payments to the applicable executive officer will be reduced by the smallest amount necessary such that no portion of the payments will be subject to such excise tax or the denial of deduction pursuant to the applicable amendment to employment agreement, if such reduction would result in a better after-tax benefit to the executive. Such reductions, if any, will not be determinable until after the consummation of the Merger since, as of the date of this proxy statement, no determinations have been made as to whether Mr. Zagorski, Mr. Allais, Mr. Mougis, or Mr. Grimmig will suffer a qualifying termination, and the year of the Closing will materially impact the calculations of amounts potentially subject to such excise taxes. The amounts reported in the golden parachute table are shown before giving effect to any such reduction. The Company and Parent have agreed to undertake mitigation strategies, to the extent reasonably available, to reduce the potential for such excise taxes.

Other Arrangements

Prior to the Effective Time, the Company, Parent, or their respective affiliates may, in their discretion, continue or initiate, as applicable, discussions regarding agreements, arrangements, and understandings with one or more of the Company’s executive officers regarding their employment or other future services, compensation or benefits and may enter into definitive agreements with such individuals regarding the foregoing (including the terms of any participation in a post-closing equity compensation program), subject to the interim operating covenants set forth in the Merger Agreement and applicable restrictions therein.

Indemnification Insurance

Except as required by applicable law, all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto existing at the time of the signing of the Merger Agreement in favor of any Indemnified Party as provided in DoubleVerify’s organizational documents and its subsidiaries’ organizational documents or in any indemnification agreement between such Indemnified Party and DoubleVerify or any of its subsidiaries will survive the Merger and continue in full force and effect, will not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party and by operation of law will be assumed by the Surviving Corporation in the Merger, without further action, at the Effective Time.

For a period of six (6) years from the Effective Time, Parent will cause the Surviving Corporation to maintain in effect the policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by DoubleVerify and its subsidiaries as of the signing of the Merger Agreement or cause to be provided substitute policies or purchase, or cause the Surviving Corporation to purchase, a “tail policy”. After the Effective Time, however, the Surviving Corporation will not be required to pay annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date of the Merger Agreement, and if such coverage costs more than 300% of such last annual premium, the Surviving Corporation will purchase the maximum amount of annual coverage obtainable for 300% of such last annual premium. This indemnification and insurance coverage is further described in the section titled, “Proposal 1: The Merger Agreement Proposal-Indemnification and Insurance.”

TABLE OF CONTENTS

Quantification of Payments and Benefits

This section sets forth the information required by Item 402(t) of Regulation S-K regarding the compensation of each named executive officer that is based on or otherwise relates to the Merger and that will or may become payable at the completion of the Merger or upon a qualifying termination. Applicable SEC disclosure rules refer to this compensation as “golden parachute” compensation. This compensation is the subject of an advisory (non-binding) vote as described in the section titled, “Proposal 2: The Compensation Proposal.”

Solely for purposes of the quantification below, the Merger is assumed to be consummated on August 31, 2026, and the equity award holdings used in the quantification are calculated as of that assumed closing date. The amounts shown in the table below are estimates based on the assumptions described in the section titled, “Interests of DoubleVerify’s Directors and Executive Officers in the Merger — Certain Assumptions” and in the footnotes to the table. The amounts do not reflect compensation actions that may occur after the date of this proxy statement and before the completion of the Merger, and do not forecast any additional equity or cash award grants, issuances, or forfeitures. Actual amounts may differ materially.

Name	Cash ($)(1)		Equity ($)(2)		Perquisites/ Benefits ($)(3)		Total ($)(4)

(1)

Amounts shown reflect the total cash severance payments that are payable pursuant to the amended severance arrangements described in the section titled, “Interests of DoubleVerify’s Directors and Executive Officers in the Merger — Amendments to Employment Agreements” and represent the estimated cash payments set forth in the table below. The amounts included in this column are considered “double-trigger” (i.e., triggered by a change in control but payable only upon a qualifying termination). The amounts are shown before giving effect to any reduction pursuant to the best-net-after-tax cutback described under “Excise Taxes Under Section 4999 of the Code.”

(2)

Amounts shown reflect the potential value that each named executive officer could receive in connection with the Merger for such named executive officer’s outstanding Company equity awards. At the Effective Time, each outstanding Company equity award will be canceled and the named executive officer will receive cash consideration or a Cash Replacement Award, as applicable. The cash consideration payable for the vested in-the-money Company Stock Options, vested Company RSUs (excluding deferred Company RSUs), and vested Earned Company PSUs is considered “single-trigger” (i.e., triggered solely by the change in control) because it will be paid in connection with the Merger regardless of whether the named executive officer has a qualifying termination. In addition, the cash consideration payable for the vested deferred Company RSUs is considered “single-trigger” (i.e., triggered solely by the change in control) because it will be paid in accordance with the named executive officer’s applicable deferral election regardless of whether the named executive officer has a qualifying termination. The Cash Replacement Awards, which will replace the unvested Company RSUs, unvested Earned Company PSUs, and Converted PSUs, are considered “double-trigger” (i.e., triggered by a change in control but payable only upon a qualifying termination) because such Cash Replacement Awards will continue to vest in

TABLE OF CONTENTS

accordance with the vesting schedule that applied to the corresponding Company equity award and accelerate only upon an involuntary termination without “Cause” or a resignation for “Good Reason” where applicable, in either case within the 12-month period following the Closing, or upon the executive’s death. Company PSU amounts assume vesting based on an estimate of actual performance as of the assumed closing date. Values are based on the Merger Consideration of $13.60 per share.

Name	Estimated Value of Single-Trigger Equity ($)		Estimated Value of Double-Trigger Equity ($)		Estimated Value of Outstanding Equity ($)
Mark Zagorski		9,010,831		11,963,716		20,974,547

Andrew Grimmig		3,460,693		4,087,195		7,547,888
Julie Eddleman		—		453,057		453,057

“Single-trigger” amounts consist of (i) vested in-the-money Company Stock Options cashed out at the Effective Time for their aggregate spread value ($7,225,831 for Mr. Zagorski, $12,432,326 for Mr. Allais, and $3,460,693 for Mr. Grimmig) and (ii) vested Company RSUs (the settlement of which was previously deferred) that are converted into a cash payment at the Effective Time and will settle in accordance with the applicable deferral election ($1,785,000 for Mr. Zagorski). No named executive officer holds any vested Earned Company PSUs. “Double-trigger” amounts consist of (i) unvested Company RSUs ($7,727,370 for Mr. Zagorski, $3,317,910 for Mr. Allais, $3,102,078 for Mr. Mougis, $2,609,881 for Mr. Grimmig, and $313,997 for Ms. Eddleman), (ii) unvested Earned Company PSUs ($1,064,078 for Mr. Zagorski, $468,765 for Mr. Allais, $75,494 for Mr. Mougis, $352,594 for Mr. Grimmig, and $139,060 for Ms. Eddleman), and (iii) Converted PSUs ($3,172,268 for Mr. Zagorski, $1,384,262 for Mr. Allais, $865,164 for Mr. Mougis, and $1,124,720 for Mr. Grimmig), each of which will be converted into Cash Replacement Awards that vest in accordance with the vesting schedule that applied to the corresponding Company equity award and accelerate only upon a qualifying termination as described above. For Ms. Eddleman, amounts are classified as “double-trigger” because acceleration of her Cash Replacement Award is contingent upon a termination of her consulting agreement without cause prior to the expiration of such agreement on September 30, 2026.

(3)

Amounts shown reflect full reimbursement of premiums for continued healthcare coverage for twenty-four (24) months for Mr. Zagorski, eighteen (18) months for Messrs. Allais and Grimmig, and twelve (12) months for Mr. Mougis. The amounts included in this column are considered “double-trigger” (i.e., amounts triggered by a change in control for which payment is also conditioned upon a qualifying termination).

(4)

No named executive officer participates in any defined benefit pension plan, and no amounts become payable under any nonqualified deferred compensation arrangement as a result of the Merger. No named executive officer is entitled to any gross-up or other reimbursement for excise taxes imposed under Section 4999 of the Code. See the section titled, “Interests of DoubleVerify’s Directors and Executive Officers in the Merger — Excise Taxes Under Section 4999 of the Code.”

Financing of the Merger

We presently anticipate that the total funds needed to complete the Merger and the related Transactions will be approximately $2,332,000,000, excluding estimated transaction fees and expenses. Parent expects these amounts to be funded through a combination of committed debt financing, equity commitments, and cash available on Parent’s and DoubleVerify’s balance sheets.

The obligation of Parent and Merger Sub to consummate the Merger is not conditioned upon receipt of financing by Parent, Merger Sub, or any of their respective Affiliates. Parent and Merger Sub have represented to the Company that, subject to satisfaction of certain conditions in the Merger Agreement, the financing provided pursuant to the Commitment Letters will provide sufficient cash proceeds, when taken together with cash available on DoubleVerify’s balance sheet and the proceeds of the Debt Financing, to satisfy all of Parent’s payment obligations under the Merger Agreement on the Closing Date. This includes funds needed to (1) pay

TABLE OF CONTENTS

DoubleVerify Stockholders the Merger Consideration due under the Merger Agreement for their Company Common Stock, (2) make payments in respect of all outstanding Company equity awards payable at the Closing pursuant to the Merger Agreement, (3) repay the existing indebtedness required (or elected) to be repaid in accordance with the Merger Agreement, and (4) pay fees and expenses related to the Merger and Transactions.

Parent and Merger Sub have obtained committed financing consisting of (1) equity to be provided by the Equity Investors pursuant to the terms of the Equity Commitment Letter and (2) debt financing to be provided pursuant to the Debt Commitment Letter by the Debt Commitment Parties. In connection with the Merger Agreement, Parent and Merger Sub have delivered to the Company copies of the Commitment Letters. Notwithstanding anything in the Merger Agreement to the contrary, in no event will the receipt or availability of any funds or financing (including the financing contemplated by the Commitment Letters) by or to Parent or any of its affiliates or any other financing transaction be a condition to any of the obligations of Parent or Merger Sub under the Merger Agreement.

Equity Commitment Letter

In connection with the financing of the Merger, the Equity Investors have entered into the Equity Commitment Letter, to severally provide an aggregate amount in immediately available funds equal to $200,000,000 to Parent and Merger Sub, for the purpose of providing Parent and Merger Sub with sufficient cash, when taken together with cash available on DoubleVerify’s balance sheet and the proceeds of the Debt Financing, to consummate the Merger and make certain cash payments required under the Merger Agreement on the Closing Date. The Company is an express third-party beneficiary of certain rights granted to Parent under the Equity Commitment Letter and is entitled to specifically have Parent enforce the obligations of the Equity Investors to fund their respective commitments under the Equity Commitment Letter in accordance with the Equity Commitment Letter and the Merger Agreement.

Each Equity Investor’s obligation to fund the Equity Financing is subject to the following conditions: (a) the execution and delivery of the Merger Agreement by the Company; (b) all of the conditions to the Closing required of DoubleVerify being satisfied or waived (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of such conditions at such time); (c) the Debt Financing having been funded at the Closing, or the Debt Commitment Parties having confirmed in writing that the Debt Financing will be funded at the Closing if the Equity Financing is funded at the Closing; and (d) the substantially simultaneous consummation of the Merger in accordance with the terms of the Merger Agreement.

The obligation of the Equity Investors to fund the Equity Financing will automatically and immediately terminate upon the earliest to occur of (1) the Closing and the funding in full of the Equity Financing (only after which the obligations under the Equity Commitment Letter will be discharged), (2) the valid termination of the Merger Agreement by Parent in accordance with its terms or the valid termination of the Merger Agreement by the Company in accordance with its terms (except in any instance in which the Company is seeking specific performance in accordance with the Merger Agreement, in which case the Equity Commitment Letter will terminate upon the date that is thirty (30) days following the final resolution of such claim) and (3) the Company or any of its subsidiaries commencing an action against the applicable Equity Investor, Parent, Merger Sub, or any of their respective affiliates, advisors or representatives in connection with the Equity Commitment Letter, the Limited Guarantee, or the Merger Agreement, other than certain permitted proceedings. The Company is an express third-party beneficiary of certain rights granted to Parent under the Equity Commitment Letter and is entitled to specifically have Parent enforce the obligations of the Equity Investors to fund their respective commitments under the Equity Commitment Letter in accordance with the terms and conditions set forth in the Equity Commitment Letter and the Merger Agreement.

Debt Commitment Letter

In addition, in connection with the financing of the Merger, Parent entered into the Debt Commitment Letter with the certain debt commitment lenders, pursuant to which the Debt Commitment Parties have committed to provide the Debt Financing. The obligations of the Debt Commitment Parties to provide Debt Financing under the Debt Commitment Letter are subject to a number of customary conditions, including, among others, (i) the consummation of the Merger in all material respects in accordance with the Merger

TABLE OF CONTENTS

Agreement, (ii) an equity investment of at least $200,000,000, (iii) the delivery of customary closing documents (including legal opinions, officer’s certificates and a solvency certificate), (iv) the accuracy of specified representations and warranties and the absence of specified events of default, (v) the receipt of specified financial statements and the expiration of a fifteen (15) business day marketing period, (vi) the receipt of customary “know your customer” documentation, (vii) the payment of fees and expenses required to be paid on the Closing Date and (viii) the refinancing of certain existing indebtedness.

Limited Guarantee

Concurrently with the execution of the Merger Agreement, the Equity Investors entered into the Limited Guarantee with the Company pursuant to which each Equity Investor has agreed to guarantee (up to an agreed upon cap) the due and punctual payment of and discharge of its pro rata percentage of the payment obligations and liabilities of Parent and Merger Sub, if, as and when due, of (a) the Parent Termination Fee to the extent that such amount is required to be paid by Parent under the Merger Agreement, (b) the recovery costs payable to the Company in enforcing the payment of the Parent Termination Fee, if applicable, and (c) the reimbursement and indemnification obligations with respect to any reasonable and documented out-of-pocket third-party costs and expenses incurred by DoubleVerify and its subsidiaries in connection with the arrangement of the Debt Financing, in each case, solely in the event of certain circumstances giving rise to a valid termination of the Merger Agreement by DoubleVerify in accordance therewith.

The Limited Guarantee will terminate and the Equity Investors will have no further obligations thereunder upon the earliest to occur of (a) the Effective Time, (b) receipt by the Company of payment in full of the Obligations (as defined in the Limited Guarantee) on the terms of the Limited Guarantee, (c) the valid termination of the Merger Agreement in accordance with its terms in circumstances in which no portion of the Obligations could be payable, and (d) sixty (60) days after the valid termination of the Merger Agreement in accordance with its terms (in circumstances other than those described in clause (c)), unless the Company has commenced a legal proceeding against the Equity Investors, Parent or Merger Sub alleging that the Parent Termination Fee is due and owing, or that Parent or Merger Sub is liable for any other Obligations under the Merger Agreement, or against the Equity Investors alleging that amounts are due and owing pursuant to the Limited Guarantee, in which case, the Limited Guarantee will terminate upon the date on which such claims are resolved by a final, non-appealable order and all amounts payable by the Equity Investors thereunder have been paid in full, or as otherwise agreed in writing by the parties to the Limited Guarantee.

Appraisal Rights

If the Merger is consummated, holders of record and beneficial owners of shares of Company Common Stock who (1) do not vote in favor of the adoption of the Merger Agreement (whether by voting against the adoption of the Merger Agreement, abstaining or otherwise not voting with respect to the adoption of the Merger Agreement), (2) properly and validly demand an appraisal of their shares of Company Common Stock in writing, (3) continuously hold (in the case of holders of record) or continuously own (in the case of beneficial owners) their shares of Company Common Stock through the Effective Time, (4) strictly comply with the statutory requirements of Section 262 of the DGCL and (5) do not withdraw their demands or otherwise lose their rights to appraisal, subject to the conditions thereof, will be entitled to seek appraisal of their shares of Company Common Stock in connection with the Merger under Section 262 of the DGCL. Unless the context requires otherwise, all references in Section 262 of the DGCL and in this summary to a “stockholder” or to a “holder of shares” are to a record holder of Company Common Stock. Unless the context requires otherwise, all references in Section 262 of the DGCL and in this summary to a “beneficial owner” are to a person who is the beneficial owner of shares of Company Common Stock held either in voting trust or by a nominee on behalf of such person. Unless the context requires otherwise, all references in Section 262 of the DGCL and in this summary to a “person” are to any individual, corporation, partnership, unincorporated association or other entity.

Persons who exercise appraisal rights under Section 262 of the DGCL will not receive the Merger Consideration they would otherwise be entitled to receive pursuant to the Merger Agreement. They will receive an amount determined to be the “fair value” of their shares of Company Common Stock following petition to, and an appraisal by, the Delaware Court of Chancery. Persons considering seeking appraisal should recognize that the fair value of their shares of Company Common Stock determined under Section 262 of the

TABLE OF CONTENTS

DGCL could be more than, the same as or less than the Merger Consideration they would otherwise be entitled to receive pursuant to the Merger Agreement. Strict compliance with the procedures set forth in Section 262 of the DGCL is required. Failure to comply strictly with all of the procedures set forth in Section 262 of the DGCL will result in the withdrawal, loss or waiver of appraisal rights. Consequently, and in view of the complexity of the provisions of Section 262 of the DGCL, persons wishing to exercise appraisal rights are urged to consult their legal and financial advisors before attempting to exercise such rights.

The following is a summary of the procedures to be followed by stockholders who wish to exercise their appraisal rights under Section 262 of the DGCL. The full text of the version of Section 262 of the DGCL applicable to the Merger Agreement is attached as Annex C to this proxy statement and may be accessed without subscription or cost at the following publicly available website:

https://delcode.delaware.gov/title8/c001/sc09/index.html#262. The following summary does not constitute any legal or other advice and does not constitute a recommendation that the DoubleVerify Stockholders or beneficial owners exercise their appraisal rights under Section 262 of the DGCL. Holders of record and beneficial owners of shares of Company Common Stock should carefully review the full text of Section 262 of the DGCL as well as the information discussed below. Failure to follow the steps required by Section 262 of the DGCL for demanding and perfecting appraisal rights will result in the loss of such rights.

Under Section 262 of the DGCL, if the Merger is completed, holders of record or beneficial owners of shares of Company Common Stock who (1) properly demand appraisal of such holder’s or owner’s shares of Company Common Stock, (2) do not vote in favor of the adoption of the Merger Agreement (whether by voting against the Merger Agreement Proposal, abstaining or otherwise not voting with respect to the adoption of the Merger Agreement), (3) continuously hold (in the case of a holder of record) or own (in the case of a beneficial owner) such shares of Company Common Stock through the effective date of the Merger, (4) do not withdraw their demands or otherwise lose their rights to appraisal, and (5) strictly comply with the statutory requirements and satisfy certain ownership thresholds set forth in Section 262 of the DGCL, may be entitled to have their shares of Company Common Stock appraised by the Delaware Court of Chancery and to receive payment in cash for the “fair value” of their shares of Company Common Stock, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with (unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown) interest on the amount determined by the Delaware Court of Chancery to be fair value from the Effective Time through the date of payment of the judgment. Unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown, interest on the amount determined to be fair value will accrue and compound quarterly from the effective date of the Merger through the date of payment of the judgment at five percent over the Federal Reserve discount rate (including any surcharge) as established from time to time during such period (except that, if at any time before the entry of judgment in the proceeding, the Surviving Corporation makes a voluntary cash payment pursuant to subsection (h) of Section 262 of the DGCL to each person seeking appraisal, interest will accrue thereafter only upon the sum of (1) the difference, if any, between the amount so paid and the fair value of the shares of Company Common Stock as determined by the Delaware Court of Chancery, and (2) interest theretofore accrued, unless paid at that time). The Surviving Corporation is under no obligation to make such voluntary cash payment prior to such entry of judgment.

However, after an appraisal petition has been filed, the Delaware Court of Chancery, at a hearing to determine persons entitled to appraisal rights, will dismiss appraisal proceedings as to all persons who are otherwise entitled to appraisal rights unless (1) the total number of shares of Company Common Stock entitled to appraisal exceeds one percent of the outstanding shares of the class of Company Common Stock eligible for appraisal (as measured in accordance with subsection (g) of Section 262 of the DGCL), or (2) the aggregate Merger Consideration in respect of the shares of Company Common Stock for which appraisal rights have been pursued and perfected exceeds $1,000,000. The Company refers to these conditions as the “ownership thresholds.”

Under Section 262 of the DGCL, where the proposed merger for which appraisal rights are provided is to be submitted for approval at a meeting of the DoubleVerify Stockholders, the corporation, not less than twenty (20) days prior to the meeting, must notify each of its stockholders of record as of the close of business on the Record Date for notice of such meeting that appraisal rights are available and include in the notice a copy of Section 262 of the DGCL or information directing the DoubleVerify Stockholders to a publicly available electronic resource at which Section 262 of the DGCL may be accessed without subscription or cost.

TABLE OF CONTENTS

This proxy statement constitutes the Company’s notice to its stockholders that appraisal rights are available in connection with the Merger, and the full text of Section 262 of the DGCL may be accessed without subscription or cost at the following publicly available website:

https://delcode.delaware.gov/title8/c001/sc09/index.html#262. In connection with the Merger, any holder of record or beneficial owner of Company Common Stock who wishes to exercise appraisal rights, or who wishes to preserve such holder’s or owner’s right to do so, should review Section 262 of the DGCL carefully. Failure to strictly comply with the requirements of Section 262 of the DGCL in a timely and proper manner will result in the loss of appraisal rights under the DGCL. A stockholder or beneficial owner who loses such holder’s or owner’s appraisal rights will be entitled to receive the Merger Consideration described in the Merger Agreement, without interest and less any required withholding tax. Because of the complexity of the procedures for exercising the right to seek appraisal of shares of Company Common Stock, the Company believes that if a stockholder or a beneficial owner is considering exercising such rights, that stockholder or beneficial owner should seek the advice of legal counsel.

Stockholders and beneficial owners wishing to exercise appraisal rights with respect to their shares of Company Common Stock must do ALL of the following:

•

the stockholder or beneficial owner must deliver to the Company a written demand for appraisal of such holder’s or owner’s shares of Company Common Stock before the vote on the adoption of the Merger Agreement at the Special Meeting;

•

the stockholder or beneficial owner must not vote in favor of the adoption of the Merger Agreement;

•

the stockholder must continuously hold or the beneficial owner must continuously own the shares of Company Common Stock from the date of making the demand through the Effective Time (a stockholder will lose appraisal rights if the stockholder transfers the shares before the Effective Time); and

•

strictly comply with the procedures of Section 262 of the DGCL for perfecting appraisal rights thereafter.

Any holder of record or beneficial owner of shares of the Company Common Stock who has complied with the applicable requirements of Section 262 of the DGCL and is otherwise entitled to appraisal rights or the Surviving Corporation may file a petition in the Delaware Court of Chancery demanding a determination of the value of the stock of all such persons within one hundred twenty (120) days after the date of the Merger. The Surviving Corporation is under no obligation to file any petition and has no intention of doing so.

In addition, after an appraisal petition has been filed, the Delaware Court of Chancery, at a hearing to determine persons entitled to appraisal rights, will dismiss appraisal proceedings as to all persons who asserted appraisal rights unless one of the ownership thresholds is met.

For stockholders, because a proxy that does not contain voting instructions will, unless revoked, be voted in favor of the adoption of the Merger Agreement, each stockholder who votes by proxy and who wishes to exercise appraisal rights must vote against the adoption of the Merger Agreement, abstain or not vote his, her or its shares of Company Common Stock.

Written Demand

A stockholder or beneficial owner wishing to exercise appraisal rights must deliver to the Company, before the vote on the adoption of the Merger Agreement at the Special Meeting, a written demand for the appraisal of such holder’s or beneficial owner’s shares of Company Common Stock. In addition, such stockholder or beneficial owner must not vote or submit a proxy in favor of the adoption of the Merger Agreement. A vote in favor of the adoption of the Merger Agreement, at the Special Meeting or by proxy (whether by mail or via the Internet or telephone), will result in loss of appraisal rights in respect of the shares of Company Common Stock so voted and will nullify any previous written demands for appraisal with respect to such stockholder’s or beneficial owner’s shares of Company Common Stock. A stockholder exercising appraisal rights must hold of record the shares of Company Common Stock on the date the written demand for appraisal is made and must continue to hold the shares of Company Common Stock of record through the effective date of the Merger. A beneficial owner exercising appraisal rights must own the shares of Company Common Stock on the date the written demand for appraisal is made and must continue to own such shares of

TABLE OF CONTENTS

Company Common Stock through the effective date of the Merger. For a stockholder, a proxy that is submitted and does not contain voting instructions will, unless revoked, be voted in favor of the adoption of the Merger Agreement, and it will constitute a waiver of the stockholder’s right of appraisal and will nullify any previously delivered written demand for appraisal. A stockholder or beneficial owner who submits a proxy and who wishes to exercise appraisal rights must submit a proxy containing instructions to vote against the adoption of the Merger Agreement or abstain from voting on the adoption of the Merger Agreement. Neither voting against the adoption of the Merger Agreement nor abstaining from voting or failing to vote on the adoption of the Merger Agreement will, in and of itself, constitute a written demand for appraisal satisfying the requirements of Section 262 of the DGCL. The written demand for appraisal must be in addition to and separate from any proxy or vote on the adoption of the Merger Agreement. A stockholder’s or beneficial owner’s failure to make the written demand prior to the taking of the vote on the adoption of the Merger Agreement at the Special Meeting will constitute a waiver of appraisal rights.

A holder of record of shares of Company Common Stock is entitled to demand appraisal for the shares of Company Common Stock registered in that holder’s name. A demand for appraisal in respect of shares of Company Common Stock by a holder of record must reasonably inform the Company of the identity of the stockholder and that the stockholder intends thereby to demand an appraisal of such stockholder’s shares of Company Common Stock.

A beneficial owner may, in such person’s name, demand in writing an appraisal of such beneficial owner’s shares of Company Common Stock. A demand for appraisal in respect of shares of Company Common Stock should be executed by or on behalf of the beneficial owner and must reasonably inform the Company of the identity of the beneficial owner and that the beneficial owner intends thereby to demand an appraisal of such owner’s shares of Company Common Stock. The demand made by such beneficial owner must also (1) reasonably identify the holder of record of the shares of Company Common Stock for which the demand is made, (2) be accompanied by documentary evidence of such beneficial owner’s continuous ownership of the stock and a statement that such documentary evidence is a true and correct copy of what it purports to be, and (3) provide an address at which such beneficial owner consents to receive notices given by the Surviving Corporation and to be set forth on the verified list required by subsection (f) of Section 262 of the DGCL. If the shares of Company Common Stock are owned of record or beneficially owned in a fiduciary or representative capacity, such as by a trustee, guardian or custodian, such demand must be executed by or on behalf of the record owner or beneficial owner, and if the shares of Company Common Stock are owned of record or beneficially owned by more than one (1) person, as in a joint tenancy and tenancy in common, the demand must be executed by or on behalf of all joint record holders or beneficial owners. An authorized agent, including an authorized agent for two (2) or more joint record holders or beneficial owners, may execute a demand for appraisal on behalf of a holder of record or beneficial owner; however, the agent must identify the record owner or owners or beneficial owner or owners, respectively, and expressly disclose that, in executing the demand, the agent is acting as agent for the record owner or owners or beneficial owner or owners, as applicable. All written demands for appraisal pursuant to Section 262 of the DGCL must be mailed or delivered to:

At any time within sixty (60) days after the effective date of the Merger (or thereafter, with written approval from the Company), any holder of record or beneficial owner of shares of the Company Common Stock who has submitted a demand for appraisal who has not commenced an appraisal proceeding or otherwise joined such proceeding as a named party will have the right to withdraw such person’s demand for appraisal and to accept the Merger Consideration offered pursuant to the Merger Agreement, without interest and less any required withholding tax, by delivering to the Company, as the Surviving Corporation, a written withdrawal of the demand for appraisal. Once a petition for appraisal is filed, an appraisal proceeding may not be dismissed as to any person without the approval of the Delaware Court of Chancery, and such approval may be conditioned upon such terms as the Delaware Court of Chancery deems just, including without

TABLE OF CONTENTS

limitation, a reservation of jurisdiction for any application to the Delaware Court of Chancery made under subsection (j) of Section 262 of the DGCL (a “Reservation”); provided, however, that this will not affect the right of any such person who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such person’s demand for appraisal and to accept the Merger Consideration within sixty (60) days after the effective date of the Merger. Except with respect to any holder of record or beneficial owner of shares of the Company Common Stock who withdraws such person’s demand in accordance with the provision in the immediately preceding sentence, if the Delaware Court of Chancery does not approve the dismissal of an appraisal proceeding with respect to such person, the person will be entitled to receive only the appraised value determined in any such appraisal proceeding, which value could be less than, equal to or more than the Merger Consideration being offered pursuant to the Merger Agreement.

Notice by the Surviving Corporation

If the Merger is completed, within ten (10) days after the Effective Time, the Surviving Corporation will notify each record holder of shares of Company Common Stock who has properly and validly made a written demand for appraisal pursuant to Section 262 of the DGCL, and who has not voted in favor of the adoption of the Merger Agreement and any beneficial owner who has demanded appraisal in accordance with Section 262 of the DGCL that the Merger has become effective and the effective date thereof.

Filing a Petition for Appraisal

Within one hundred twenty (120) days after the effective date of the Merger, but not thereafter, the Surviving Corporation or any holder of record or beneficial owner of shares of the Company Common Stock who has complied with Section 262 of the DGCL and who is entitled to appraisal rights under Section 262 of the DGCL may commence an appraisal proceeding by filing a petition in the Delaware Court of Chancery, with a copy served on the Surviving Corporation in the case of a petition filed by a person, demanding a determination of the fair value of the shares of Company Common Stock held by all such persons entitled to appraisal. The Surviving Corporation is under no obligation, and has no present intention, to file a petition, and holders of record and beneficial owners of shares of Company Common Stock should not assume that the Surviving Corporation will file a petition or initiate any negotiations with respect to the fair value of the shares of Company Common Stock. Accordingly, any such persons who desire to have their shares of Company Common Stock appraised should take all actions necessary to perfect their appraisal rights in respect of their shares of Company Common Stock within the time and in the manner prescribed in Section 262 of the DGCL. The failure to file such a petition within the period specified in Section 262 of the DGCL will nullify a previous written demand for appraisal.

Within one hundred twenty (120) days after the effective date of the Merger, any holder or beneficial owner of shares of the Company Common Stock who has complied with the requirements for an appraisal of such person’s shares of Company Common Stock pursuant to Section 262 of the DGCL and who is entitled to appraisal rights under Section 262 of the DGCL will be entitled, upon written request, to receive from the Surviving Corporation a statement setting forth the aggregate number of shares of Company Common Stock not voted in favor of the adoption of the Merger Agreement and with respect to which the Company has received demands for appraisal, and the aggregate number of stockholders or beneficial owners holding or owning such shares of Company Common Stock (provided that, where a beneficial owner makes a demand pursuant to Section 262 of the DGCL, the holder of record of such shares of Company Common Stock will not be considered a separate stockholder holding such shares of Company Common Stock for purposes of such aggregate number). The Surviving Corporation must send this statement to the requesting person within ten (10) days after receipt by the Surviving Corporation of the written request for such a statement or within ten (10) days after the expiration of the period for delivery of demands for appraisal, whichever is later.

If a petition for an appraisal is duly filed by a holder or beneficial owner of shares of the Company Common Stock and a copy thereof is served upon the Surviving Corporation, the Surviving Corporation will then be obligated within twenty (20) days after such service to file with the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all such persons who have demanded appraisal for their shares of Company Common Stock and with whom agreements as to the value of their shares of Company Common Stock have not been reached. The Register in Chancery, if so ordered by the Delaware Court of Chancery, will give notice of the time and place fixed for the hearing of

TABLE OF CONTENTS

such petition by mail to the Surviving Corporation and to the persons shown on such list at the addresses stated therein. The forms of the notices by mail and by publication will be approved by the Delaware Court of Chancery and the costs of any such notice are borne by the Surviving Corporation.

After providing the foregoing notice, at the hearing on such petition, the Delaware Court of Chancery will determine the persons who have complied with Section 262 of the DGCL and who are entitled to appraisal rights thereunder. The Delaware Court of Chancery may require the persons who demanded appraisal for their shares and who hold stock represented by certificates to submit their stock certificates to the Delaware Register in Chancery for notation thereon of the pendency of the appraisal proceedings. If any person fails to comply with the direction, the Delaware Court of Chancery may dismiss the proceedings as to such person. Accordingly, persons seeking appraisal of their shares of the Company Common Stock are cautioned to retain their Company Common Stock certificates pending resolution of the appraisal proceedings.

The Delaware Court of Chancery will dismiss appraisal proceedings as to all holders or beneficial owners of shares of the Company Common Stock who are otherwise entitled to appraisal rights unless (1) the total number of shares of Company Common Stock entitled to appraisal exceeds one percent of the outstanding shares of the class of Company Common Stock eligible for appraisal (as measured in accordance with subsection (g) of Section 262 of the DGCL) or (2) the value of the consideration provided in the Merger for such total number of shares of Company Common Stock entitled to appraisal exceeds $1,000,000.

Determination of Fair Value

After the Delaware Court of Chancery determines the persons entitled to appraisal, and that at least one (1) of the ownership thresholds above has been satisfied, then the appraisal proceeding will be conducted in accordance with the rules of the Delaware Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding, the Delaware Court of Chancery will determine the “fair value” of the shares of Company Common Stock, exclusive of any element of value arising from the accomplishment or expectation of the Merger, together with interest, if any, to be paid upon the amount determined to be the fair value (subject, in the case of interest payments, to any voluntary payments made by the Surviving Corporation pursuant to subsection (h) of Section 262 of the DGCL that have the effect of limiting the sum on which interest accrues as described below). In determining fair value, the Delaware Court of Chancery will take into account all relevant factors. Unless the Delaware Court of Chancery in its discretion determines otherwise for good cause shown, interest from the Effective Time through the date of payment of the judgment will be compounded quarterly and will accrue at five percent (5%) over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the Effective Time and the date of payment of the judgment. However, the Surviving Corporation has the right, at any time prior to the Delaware Court of Chancery’s entry of judgment in the proceedings, to make a voluntary cash payment to each person seeking appraisal. If the Surviving Corporation makes a voluntary cash payment pursuant to subsection (h) of Section 262 of the DGCL to each person entitled to appraisal, interest will accrue thereafter only on the sum of (1) the difference, if any, between the amount paid by the Surviving Corporation in such voluntary cash payment and the fair value of the shares of Company Common Stock as determined by the Delaware Court of Chancery, and (2) interest accrued before such voluntary cash payment, unless paid at that time.

In Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered, and that “[f]air price obviously requires consideration of all relevant factors involving the value of a company.” The Delaware Supreme Court stated that, in making this determination of fair value, the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts that could be ascertained as of the date of the Merger that throw any light on future prospects of the merged corporation. Section 262 of the DGCL provides that fair value is to be “exclusive of any element of value arising from the accomplishment or expectation of the merger.” In Cede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a “narrow exclusion [that] does not encompass known elements of value,” but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Supreme Court of Delaware also stated that “elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered.”

TABLE OF CONTENTS

Persons considering seeking appraisal should be aware that the fair value of their shares of Company Common Stock as so determined by the Delaware Court of Chancery could be more than, the same as or less than the Merger Consideration they would receive pursuant to the Merger if they did not seek appraisal of their shares of Company Common Stock and that an opinion of an investment banking firm as to the fairness from a financial point of view of the consideration payable in a merger is not an opinion as to, and may not in any manner address, fair value under Section 262 of the DGCL. Although the Company believes that the Merger Consideration is fair, no representation is made as to the outcome of the appraisal of fair value as determined by the Delaware Court of Chancery, and holders of record and beneficial owners of Company Common Stock should recognize that such an appraisal could result in a determination of a value higher or lower than, or the same as, the Merger Consideration. Neither the Company nor Parent anticipates offering more than the Merger Consideration to any stockholder or beneficial owner exercising appraisal rights, and the Surviving Corporation reserves the rights to make a voluntary cash payment pursuant to subsection (h) of Section 262 of the DGCL and to assert, in any appraisal proceeding, that for purposes of Section 262 of the DGCL, the “fair value” of a share of Company Common Stock is less than the Merger Consideration.

The costs of the appraisal proceedings (which do not include attorneys’ fees or the fees and expenses of experts) may be determined by the Delaware Court of Chancery and taxed upon the parties as the Delaware Court of Chancery deems equitable under the circumstances. Upon application of a person whose name appears on the list filed by the Surviving Corporation pursuant to Section 262(f) of the DGCL who participated in the proceeding and incurred expenses in connection therewith, the Delaware Court of Chancery may also order that all or a portion of such expenses, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares of Company Common Stock entitled to an appraisal not dismissed pursuant to subsection (k) of Section 262 of the DGCL or subject to such an award pursuant to a Reservation. In the absence of such determination or assessment, each party bears its own expenses.

If any person who demands appraisal of his, her or its shares of Company Common Stock under Section 262 of the DGCL fails to perfect, or loses or validly withdraws, such person’s right to appraisal, such person’s shares of Company Common Stock will be deemed to have been converted at the Effective Time into the right to receive the Merger Consideration as provided in the Merger Agreement, without interest and less any required withholding tax. A person will fail to perfect, or effectively lose, such person’s right to appraisal if no petition for appraisal is filed within one hundred twenty (120) days after the effective date of the Merger, if neither of the ownership thresholds above has been satisfied in respect of persons seeking appraisal rights or if the person delivers to the Surviving Corporation a written withdrawal of such person’s demand for appraisal and an acceptance of the Merger Consideration as provided in the Merger Agreement in accordance with Section 262 of the DGCL.

From and after the Effective Time, no person who has demanded appraisal rights with respect to some or all of such person’s shares of Company Common Stock in compliance with Section 262 of the DGCL will be entitled to vote such shares of Company Common Stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the Effective Time). If a person who has made a demand for an appraisal in accordance with Section 262 of the DGCL delivers to the Surviving Corporation a written withdrawal of such person’s demand for an appraisal in respect of some or all of such person’s shares, either within sixty (60) days after the effective date of the Merger or thereafter with the Surviving Corporation’s written approval, then the right of such person to an appraisal of the shares subject to the withdrawal will cease. Notwithstanding the foregoing, no appraisal proceeding in the Delaware Court of Chancery will be dismissed as to any person without the approval of the Delaware Court of Chancery, and such approval may be conditioned upon such terms as the Delaware Court of Chancery deems just, including, without limitation, a Reservation; provided, however, that the foregoing will not affect the right of any person who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such person’s demand for appraisal and to accept the Merger Consideration within sixty (60) days after the Effective Time. If a petition for an appraisal is not filed within the time provided in accordance with Section 262 of the DGCL, the right to appraisal with respect to all shares of Company Common Stock will cease.

Failure to comply strictly with all of the procedures set forth in Section 262 of the DGCL will result in the loss of a person’s appraisal rights under Section 262 of the DGCL. In that event, such person will be entitled

TABLE OF CONTENTS

to receive the Merger Consideration for such person’s shares of Company Common Stock in accordance with the Merger Agreement, without interest and less any required withholding tax. Consequently, any holder of record or beneficial owner of shares of the Company Common Stock wishing to exercise appraisal rights is encouraged to consult legal counsel before attempting to exercise those rights.

STOCKHOLDERS OR BENEFICIAL OWNERS OF SHARES OF COMPANY COMMON STOCK WHO VOTE SHARES OF COMPANY COMMON STOCK IN FAVOR OF THE ADOPTION OF THE MERGER AGREEMENT WILL NOT BE ENTITLED TO EXERCISE APPRAISAL RIGHTS WITH RESPECT THERETO BUT, RATHER, WILL RECEIVE THE MERGER CONSIDERATION.

Accounting Treatment

The Merger will be accounted for as a “business combination” for financial accounting purposes.

Certain Material U.S. Federal Income Tax Consequences of the Merger

The following discussion is a summary of certain material U.S. federal income tax consequences of the Merger that may be relevant to U.S. Holders and Non-U.S. Holders (each as defined in this proxy statement) of shares of Company Common Stock whose shares are converted into the right to receive cash pursuant to the Merger. This discussion is limited to DoubleVerify Stockholders who hold their shares of Company Common Stock as “capital assets” within the meaning of Section 1221 of the Internal Revenue Code of 1986, as amended (the “Code”) (generally, property held for investment purposes). This discussion is based upon the Code, Treasury Regulations promulgated under the Code, rulings and other published positions of the Internal Revenue Service (the “IRS”) and judicial decisions, all as in effect on the date of this proxy statement and all of which are subject to change or differing interpretations at any time, possibly with retroactive effect. Any such change or differing interpretation could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion is not binding on the IRS or the courts and, accordingly, the IRS may assert, or a court may sustain, a position contrary to any of the tax consequences described in this discussion. No advance ruling has been or will be sought from the IRS regarding any matter discussed below.

This discussion is for general information purposes only and does not purport to be a complete analysis of all of the U.S. federal income tax consequences that may be relevant to particular holders in light of their particular facts and circumstances, or to DoubleVerify Stockholders subject to special rules under U.S. federal income tax laws, including, for example, but not limited to:

•

banks and other financial institutions;

•

insurance companies;

•

brokers or dealers in securities, currencies or commodities;

•

dealers or traders in securities subject to a mark-to-market method of accounting with respect to shares of Company Common Stock;

•

regulated investment companies and real estate investment trusts;

•

retirement plans, individual retirement and other tax-deferred accounts;

•

tax-exempt organizations, governmental agencies, instrumentalities or other governmental organizations and pension funds;

•

holders that are holding shares of Company Common Stock as part of a “straddle,” hedge, constructive sale, or other integrated transaction or conversion transaction or similar transactions;

•

U.S. Holders whose functional currency is not the U.S. dollar;

•

partnerships, other entities classified as partnerships for U.S. federal income tax purposes, “S corporations,” or any other pass-through entities for U.S. federal income tax purposes (or investors in such entities);

•

expatriated entities subject to Section 7874 of the Code;

•

holders that are required to accelerate the recognition of any item of gross income as a result of such income being recognized on an “applicable financial statement”;

TABLE OF CONTENTS

•

persons subject to alternative minimum taxes;

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

holders that own or at any time during the five (5)-year period ending on the date of the Merger have owned (directly, indirectly or constructively) more than five percent (5%) of Company Common Stock;

•

grantor trusts;

•

controlled foreign corporations, passive foreign investment companies, and corporations that accumulate earnings to avoid U.S. federal income tax;

•

holders that received their shares of Company Common Stock in a compensatory transaction, through a tax qualified retirement plan or pursuant to the exercise of options or warrants;

•

holders that own an indirect equity interest in Parent following the Merger;

•

holders that hold their shares of Company Common Stock through a bank, financial institution or other entity, or a branch thereof, located, organized or resident outside the United States;

•

holders that do not vote in favor of the Merger and that properly demand appraisal of their shares of Company Common Stock under Section 262 of the DGCL; and

•

holders whose Company Common Stock qualifies as qualified small business stock.

This discussion does not address any U.S. federal tax consequences other than those pertaining to the income tax (such as estate, gift or other non-income tax consequences) or any state, local or non-U.S. income or non-income tax consequences. In addition, this discussion does not address any consequences arising under the Medicare contribution tax.

If a partnership (including an entity or arrangement treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of shares of Company Common Stock, the U.S. federal income tax consequences of the Merger to a partner in such partnership will generally depend upon the status of the partner, the activities of the partner and the partnership, and certain determinations made at the partner level. Each Partnership holding shares of Company Common Stock and each partner therein is urged to consult its tax advisors regarding the consequences to it of the Merger.

THE U.S. FEDERAL INCOME TAX TREATMENT OF THE TRANSACTIONS DISCUSSED HEREIN TO ANY PARTICULAR DOUBLEVERIFY STOCKHOLDER WILL DEPEND ON SUCH STOCKHOLDER’S PARTICULAR TAX CIRCUMSTANCES. WE URGE EACH DOUBLEVERIFY STOCKHOLDER TO CONSULT ITS TAX ADVISOR WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES TO IT IN CONNECTION WITH THE MERGER IN LIGHT OF ITS PARTICULAR CIRCUMSTANCES, INCLUDING U.S. FEDERAL, STATE, LOCAL AND NON-U.S. INCOME AND OTHER TAX CONSEQUENCES.

U.S. Holders

This section applies to “U.S. Holders.” For purposes of this discussion, a “U.S. Holder” means a beneficial owner of shares of Company Common Stock that is for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation, or other entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

•

a trust, if (i) a court within the United States is able to exercise primary supervision over the administration of such trust and one (1) or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) have the authority to control all substantial decisions of the trust or (ii) the trust validly elected to be treated as a “United States person” (within the meaning of Section 7701(a)(30) of the Code) for U.S. federal income tax purposes.

The receipt of cash by a U.S. Holder in exchange for shares of Company Common Stock pursuant to the Merger will be a taxable transaction for U.S. federal income tax purposes. In general, a U.S. Holder will

TABLE OF CONTENTS

recognize gain or loss in an amount equal to the difference, if any, between the amount of cash received with respect to, and the U.S. Holder’s adjusted tax basis in the shares of Company Common Stock surrendered pursuant to, the Merger. A U.S. Holder’s adjusted tax basis will generally equal the amount that such U.S. Holder paid for the shares of Company Common Stock. A U.S. Holder’s gain or loss on the disposition of shares of Company Common Stock will generally be characterized as capital gain or loss. Any such gain or loss will be long-term capital gain or loss if such U.S. Holder’s holding period in such shares is more than one (1) year at the time of the completion of the Merger. A preferential tax rate on capital gain will generally apply to long-term capital gain of a non-corporate U.S. Holder (including an individual). The deductibility of capital losses is subject to limitations. Gain or loss must be determined separately for each block of Company Common Stock (i.e., shares of Company Common Stock purchased or acquired on different dates or at different prices) disposed of pursuant to the Merger.

Non-U.S. Holders

This section applies to “Non-U.S. Holders.” For purposes of this discussion, a “Non-U.S. Holder” means a beneficial owner of Company Common Stock that is not a U.S. Holder.

Subject to the discussion of backup withholding below, a Non-U.S. Holder will generally not be subject to U.S. federal income or withholding tax in respect of gain recognized in connection with the Merger, unless:

•

such gain is effectively connected with a trade or business of such Non-U.S. Holder in the United States (and, if required by an applicable and properly claimed income tax treaty, is attributable to a permanent establishment or fixed base maintained by such Non-U.S. Holder in the United States), in which case such gain will generally be subject to U.S. federal income tax at rates generally applicable to U.S. persons, and, if such Non-U.S. Holder is a corporation, such gain may also be subject to the additional branch profits tax at a rate of thirty percent (30%) (or a lower rate under an applicable and properly claimed income tax treaty);

•

such Non-U.S. Holder is an individual who is present in the United States for one hundred eighty three (183) days or more in the taxable year of disposition of shares of Company Common Stock pursuant to the Merger, and certain other specified conditions are met, in which case such gain (net of certain U.S.-source losses provided such Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses) will be subject to U.S. federal income tax at a rate of thirty percent (30%) (or a lower rate under an applicable and properly claimed income tax treaty); or

•

the shares of Company Common Stock constitute a United States real property interest (“USRPI”), as defined in Section 897(c)(1) of the Code, by reason of the Company’s status as a United States real property holding corporation (“USRPHC”), as defined in Section 897(c)(2) of the Code, for U.S. federal income tax purposes during the shorter of the five-year period ending at the time of the Merger and the Non-U.S. Holder’s holding period for the shares of Company Common Stock, and, as discussed below, one or more other conditions are satisfied.

If the Company is (or was during the above period) a USRPHC, gain recognized as a result of the Merger by a Non-U.S. Holder will not be subject to U.S. federal income or withholding tax by reason of the Company’s USRPHC status if (i) the shares of Company Common Stock are “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, and (ii) such Non-U.S. Holder owned, actually and constructively, five percent (5%) or less of the shares of Company Common Stock throughout the shorter of the five-year period ending on the date of the Merger or the Non-U.S. Holder’s holding period.

We believe that we are not (and have not been during the relevant time period) a USRPHC and that the Company Common Stock is regularly traded on an established securities market. Accordingly, a Non-U.S. Holder is not expected to be subject to income taxes (or withholding taxes) under these rules upon the exchange of the Company Common Stock pursuant to the Merger.

Each Non-U.S. Holder is urged to consult its tax advisor about the consequences that could result if the Company was, or is a USRPHC.

Information Reporting and Backup Withholding

Generally, information reporting requirements may apply in connection with payments made to U.S. Holders or Non-U.S. Holders in connection with the Merger.

TABLE OF CONTENTS

Backup withholding of tax (at the applicable rate) will generally apply to the Merger Consideration received by a U.S. Holder pursuant to the Merger, unless the U.S. Holder provides the applicable withholding agent with a properly completed and executed IRS Form W-9 providing such U.S. Holder’s correct taxpayer identification number and certifying that such U.S. Holder is not subject to backup withholding, or otherwise establishes an exemption, and otherwise complies with the backup withholding rules. Backup withholding of tax may also apply to the Merger Consideration received by a Non-U.S. Holder pursuant to the Merger, unless the Non-U.S. Holder provides the applicable withholding agent with a properly completed and executed IRS Form W-8BEN or IRS Form W-8BEN-E (or other applicable IRS Form W-8), in each case together with all appropriate attachments, attesting to such Non-U.S. Holder’s status as a non-U.S. person and otherwise complies with applicable certification requirements.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a DoubleVerify Stockholder may generally be allowed as a credit against such holder’s U.S. federal income tax liability, if any, and may entitle such DoubleVerify Stockholder to a refund, provided that the required information is timely furnished to the IRS.

THE DISCUSSION ABOVE IS BASED ON CURRENT LAW. LEGISLATIVE, ADMINISTRATIVE OR JUDICIAL CHANGES OR INTERPRETATIONS, WHICH CAN APPLY RETROACTIVELY, COULD AFFECT THE ACCURACY OF THE STATEMENTS SET FORTH THEREIN. THIS DISCUSSION IS FOR GENERAL INFORMATION PURPOSES ONLY AND DOES NOT CONSTITUTE TAX ADVICE. IT DOES NOT ADDRESS TAX CONSEQUENCES THAT MAY VARY WITH, OR ARE CONTINGENT ON, A DOUBLEVERIFY STOCKHOLDER’S INDIVIDUAL CIRCUMSTANCES OR THE APPLICATION OF ANY U.S. NON-INCOME TAX LAWS OR THE LAWS OF ANY STATE, LOCAL OR NON-U.S. JURISDICTION AND EACH DOUBLEVERIFY STOCKHOLDER IS URGED TO CONSULT ITS TAX ADVISOR REGARDING SUCH MATTERS AND THE TAX CONSEQUENCES OF THE MERGER TO IT IN LIGHT OF ITS PARTICULAR CIRCUMSTANCES.

Regulatory Approvals Required for the Merger

General

Pursuant to the Merger Agreement, each of the parties has agreed to use its reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, and cooperate with each other in order to do, all things necessary, proper or advisable under Antitrust Law (as defined below) to consummate the Transactions at the earliest practicable date. The parties have agreed to prepare and file as promptly as practicable (and in any event no later than twenty (20) business days from the date of the Merger Agreement) appropriate filings under the antitrust laws in the jurisdictions identified by the parties, including the Australian Competition and Consumer Act 2010 (Cth), the Cyprus Control of Concentrations Between Undertakings Law of 2014 (Law 83(I)/2014), the German Act Against Restraints of Competition (Gesetz gegen Wettbewerbsbeschränkungen) and the Moroccan Law No. 104-12 on Freedom of Prices and Competition (Loi n° 104-12 sur la liberté des prix et de la concurrence), subject to certain limitations as outlined in the section of this proxy statement titled “Proposal 1: The Merger Agreement Proposal — Antitrust.”

For purposes of the Merger Agreement and the references in this proxy statement, “Antitrust Law” means the Sherman Act of 1890, as amended, the Clayton Antitrust Act of 1914, as amended, the HSR Act, the Federal Trade Commission Act, as amended, foreign antitrust or competition laws, and all other laws that are designed or intended to prohibit, restrict or regulate actions having the purpose or effect of monopolization or restraint of trade or lessening of competition through merger or acquisition.

HSR Act and Antitrust Matters

Under the HSR Act and the rules promulgated thereunder, the Merger may not be completed until DoubleVerify and Parent each files a Notification and Report Form with the DOJ and the FTC, and the applicable waiting period has expired or been terminated. A transaction notifiable under the HSR Act may not be completed until the expiration or termination of a thirty (30)-calendar-day waiting period following the parties’ filings of their respective HSR Act Notification and Report Forms. If the FTC or DOJ issues a

TABLE OF CONTENTS

Second Request prior to the expiration of the initial waiting period, the parties must observe a second thirty (30)-day waiting period, which would begin to run only after both parties have substantially complied with the Second Request, unless the waiting period is terminated earlier, the parties agree to extend any applicable waiting period, or the parties otherwise agree to delay the Closing.

The Company and Parent each filed a Notification and Report Form with respect to the Merger with the FTC and DOJ on August 20, 2026 and the applicable waiting period will expire on 11:59 p.m. Eastern Time on September 21, 2026, unless the FTC or the DOJ earlier terminates the waiting period, the period is lengthened by a pull-and-refile, or the FTC or the DOJ issues a Second Request.

The Merger is also conditioned on the expiration or termination of any agreement not to consummate the Merger with any governmental body, and the receipt of any requisite approvals or clearances under the Antitrust Laws and competition laws of Australia, Cyprus, Germany and Morocco, unless the relevant jurisdiction declines, does not assert or defers jurisdiction.

At any time before or after consummation of the Merger, notwithstanding the termination or expiration of the waiting period under the HSR Act, the FTC or the DOJ could take such action under the Antitrust Laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the Merger, seeking divestiture of substantial assets of the parties, or requiring the parties to license or hold separate assets or terminate existing relationships and contractual rights. At any time before or after the completion of the Merger, any state could take such action under the Antitrust Laws as it deems necessary or desirable in the public interest. Such action could include seeking to enjoin the completion of the Merger or seeking divestiture of substantial assets of the parties.

Private parties may also seek to take legal action under the Antitrust Laws under certain circumstances. We cannot be certain that a challenge to the Merger will not be made or that, if a challenge is made, we will prevail.

PROPOSAL 1: THE MERGER AGREEMENT PROPOSAL

This section describes the material terms and conditions of the Merger Agreement. The description of the Merger Agreement in this section and elsewhere in this proxy statement is qualified in its entirety by reference to the complete text of the Merger Agreement, a copy of which is attached to this proxy statement as Annex A and is incorporated by reference into this proxy statement. This summary does not purport to be complete and may not contain all of the information about the Merger Agreement that is important to you. We encourage you to read the Merger Agreement carefully and in its entirety. The rights and obligations of the parties are governed by the express terms of the Merger Agreement and not by this summary or any other information contained in this proxy statement. This section is not intended to provide you with factual information about DoubleVerify or any of its subsidiaries or affiliates. Such information can be found elsewhere in this proxy statement and in the public filings DoubleVerify makes with the SEC, which may be obtained by following the instructions set forth in the section titled “Where You Can Find More Information” beginning on page 126.

Explanatory Note Regarding the Merger Agreement

The Merger Agreement and the description of the Merger Agreement have been included to provide investors with information regarding the terms of the Merger Agreement. It is not intended to provide any other factual information about DoubleVerify, Parent, Merger Sub or their respective subsidiaries or affiliates. The representations, warranties and covenants contained in the Merger Agreement were made only for purposes of the Merger Agreement and as of specific agreed upon dates, were solely for the benefit of the parties to the Merger Agreement and may be subject to limitations, qualifications and supplemental information agreed upon by the parties in connection with negotiating the terms of the Merger Agreement, including being qualified by confidential disclosures made by each party for the purposes of allocating contractual risk between the parties. In addition, certain representations and warranties may be subject to contractual standards of materiality different from those generally applicable to investors and may have been used for the purpose of allocating risk between the parties rather than establishing matters as facts. Information concerning the subject matter of the representations, warranties and covenants may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in public disclosures by DoubleVerify. The Merger Agreement should not be read alone, but should instead be read in conjunction with the other information regarding the parties that is contained in, or incorporated by reference into, this proxy statement, DoubleVerify’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, proxy statements and Current Reports on Form 8-K. Except in certain limited circumstances expressly specified in the Merger Agreement, DoubleVerify Stockholders are not third-party beneficiaries under the Merger Agreement and should not rely on the representations, warranties and covenants or any description thereof as characterizations of the actual state of facts or condition of DoubleVerify, Parent or any of their respective subsidiaries, affiliates or businesses. Additionally, the representations, warranties, covenants, conditions and other terms of the Merger Agreement may be subject to subsequent waiver, amendments or other modification.

Form and Effects of the Merger; Certificate of Incorporation and Bylaws; Directors and Officers

Upon the terms and subject to the conditions set forth in the Merger Agreement and the applicable provisions of the DGCL, at the Effective Time, Merger Sub will be merged with and into DoubleVerify. Upon consummation of the Merger, the separate corporate existence of Merger Sub will cease and DoubleVerify will continue as the Surviving Corporation and a wholly owned subsidiary of Parent.

At the Effective Time, DoubleVerify’s certificate of incorporation in effect immediately prior to the Effective Time, by virtue of the Merger and without any further action on the part of any person, will be amended and restated so that it reads in its entirety as set forth in Exhibit B to the Merger Agreement, and, as so amended, will be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with its terms and as provided by the DGCL.

Also at the Effective Time, by virtue of the Merger and without any further action on the part of any person, DoubleVerify’s bylaws will be amended and restated to read in their entirety as the bylaws of Merger Sub in effect immediately prior to the Effective Time (with any changes as DoubleVerify and Parent may mutually agree in writing), except that all references therein to Merger Sub shall be automatically amended and shall become references to the Surviving Corporation, and, as so amended, will be the bylaws of the

TABLE OF CONTENTS

Surviving Corporation until thereafter amended in accordance with their terms, the certificate of incorporation of the Surviving Corporation and as provided by the DGCL.

As of the Effective Time, the directors of Merger Sub as of immediately prior to the Effective Time will be the directors of the Surviving Corporation, each to serve until his or her respective successor is duly elected and qualified or until the earlier of his or her death, resignation or removal.

The officers of DoubleVerify immediately prior to the Effective Time will be the officers of the Surviving Corporation, each such officer to serve until his or her respective successor is duly elected and qualified or until the earlier of his or her death, resignation or removal.

Consummation and Effectiveness of the Merger

Unless another time or date is mutually agreed in writing by Parent and DoubleVerify, the Closing will take place as soon as practicable, but in any event no later than the date which is three (3) business days after the date on which all conditions set forth in the Merger Agreement have been satisfied or waived and described in the section titled “Proposal 1: The Merger Agreement Proposal — Conditions to Consummation of the Merger,” other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction of such conditions at such time. If the Marketing Period has not ended, the Closing will not occur until the earlier of (a) a Business Day, if any, during the Marketing Period specified by Parent on no less than three (3) business days’ notice to DoubleVerify and (b) three (3) business days following the final day of the Marketing Period.

Consideration to be Received in the Merger

At the Effective Time, subject to the terms and conditions of the Merger Agreement, by virtue of the Merger, the following will occur:

•

Each share of Company Common Stock issued and outstanding as of immediately prior to the Effective Time will be automatically converted into and shall thereafter represent the right to receive the Merger Consideration, except that no Merger Consideration will be paid with respect to any shares of Company Common Stock, (A) owned directly or indirectly by Parent, Merger Sub or any direct or indirect wholly owned subsidiary of Parent, Merger Sub or DoubleVerify, (B) any shares held by the Company (including those held in the Company’s treasury) or (C) any Dissenting Shares;

•

all shares of Company Common Stock will no longer be outstanding and will automatically be canceled and cease to exist, and thereafter only represent the right to receive the Merger Consideration, without interest and subject to deduction for any required withholding tax (except for holders of Dissenting Shares, as described above and in the section titled “The Merger — Appraisal Rights”).

Treatment of Equity Awards in the Merger

The Company has granted Company Stock Options, Company RSUs, and Company PSUs. At the Effective Time, the awards will be treated as follows:

•

Each vested, in-the-money Company Stock Option, including awards that vest in connection with the Closing, will be cashed out for its aggregate spread value (based on the excess of the Merger Consideration over the per-Share exercise price and the number of shares of Company Common Stock underlying such Company Stock Option). Each unvested, in-the-money Company Stock Option will be converted to a Cash Replacement Award equal to its aggregate spread value which will vest and be paid out on the same vesting terms that applied to the corresponding Company Stock Option. All underwater Company Stock Options (whether vested or unvested) will be canceled for no consideration.

•

Each vested Company RSU, including awards that vest in connection with the Closing, will be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares

TABLE OF CONTENTS

of Company Common Stock subject to such vested Company RSU. Each unvested Company RSU will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of unvested shares of Company Common Stock subject to such Company RSU, which will vest and be paid out on the same vesting terms that applied to the corresponding Company RSU.

•

Each Company PSU as to which the applicable performance-based vesting conditions have been satisfied, including awards that vest in connection with the Closing, will, to the extent vested as of immediately prior to the Effective Time, be cashed out for an amount in cash equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such vested Earned Company PSU (with the performance conditions deemed achieved based on actual performance as of immediately before the Effective Time). Each Company PSU that is not an Earned Company PSU will be converted into a Converted PSU with respect to the number of shares of Company Common Stock determined by the Compensation Committee based on performance through the Effective Time, in accordance with the underlying award agreement, subject to Parent’s review and reasonable comment. Each Converted PSU will be converted into the right to receive a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such Converted PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Converted PSU. Each unvested Earned Company PSU will be converted to a Cash Replacement Award equal to the product of the Merger Consideration and the number of shares of Company Common Stock subject to such unvested Earned Company PSU, which Cash Replacement Award will vest and be paid out on the same terms that applied to the corresponding Earned Company PSU.

•

All Cash Replacement Awards will accelerate upon a severance-eligible employment termination within twelve months following the Effective Time, or the holder’s death.

Each Cash Replacement Award will be payable solely in cash. A Company RSU or Earned Company PSU that is vested but subject to a deferral election under Section 409A of the Code will be treated as unvested for these purposes. In addition, to the extent any Company Stock Option, Company RSU, Company PSU, Earned Company PSU, or Converted PSU (or the Cash Replacement Award issued in respect thereof) constitutes “nonqualified deferred compensation” within the meaning of Section 409A of the Code, the corresponding Cash Replacement Award will instead be paid on the settlement or payment dates, and in the form, that applied to such award immediately prior to the Effective Time. Parent will cause the Surviving Corporation or its applicable subsidiary to assume and honor each Cash Replacement Award. Each Cash Replacement Award will provide that, upon (i) an involuntary termination of the holder without “Cause” within the 12-month period immediately following the Closing, (ii) if the applicable award agreement or employment-related agreement provides for a “Good Reason” definition, a voluntary resignation of the holder with “Good Reason” within the 12-month period immediately following the Closing, or (iii) the death of the holder, in each case prior to the final vesting date of such Cash Replacement Award, the then-unvested portion of such Cash Replacement Award will immediately vest and be paid in full.

Procedures for Receiving Merger Consideration

Prior to the Effective Time, Parent will enter into an agreement, in form and substance reasonably acceptable to DoubleVerify, with DoubleVerify’s transfer agent, or any other reputable bank or trust company reasonably acceptable to DoubleVerify and Parent, to act as agent for the holders of shares of Company Common Stock (other than Excluded Shares and any Dissenting Shares) to receive the Merger Consideration to which such holders will become entitled pursuant to the Merger Agreement, and to act as agent for DoubleVerify Stockholders in connection with the Merger (the “Paying Agent”). At or prior to or substantially concurrently with the Effective Time, Parent will deposit (or cause to be deposited) with the Paying Agent an aggregate amount of cash that, when taken together with cash available on DoubleVerify’s balance sheet that is deposited with the Paying Agent at the Effective Time, is sufficient to pay the aggregate Merger Consideration in accordance with the Merger Agreement (the “Payment Fund”). The Payment Fund will not be used for any purpose other than to fund payments of the Merger Consideration due pursuant to the Merger Agreement. Parent will cause the Paying Agent to, pursuant to irrevocable instructions delivered by Parent to the Paying Agent, deliver the Merger Consideration out of the Payment Fund. The Surviving Corporation will, and Parent will cause the Surviving Corporation to, pay all charges and expenses, including those of the

TABLE OF CONTENTS

Paying Agent, incurred in connection with the exchange of shares of Company Common Stock for the Merger Consideration and other amounts contemplated by the Merger Agreement.

As promptly as reasonably practicable following the Effective Time (and in any event not later than the third Business Day following the Effective Time), Parent shall cause the Paying Agent to mail to each holder of record of an outstanding certificate or outstanding certificates (“Certificates”) that immediately prior to the Effective Time represented outstanding shares of Company Common Stock that were converted into the right to receive the Merger Consideration (i) a form of letter of transmittal, which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon proper delivery of the Certificates to the Paying Agent, and (ii) instructions for use in effecting the surrender of such Certificates in exchange for the Merger Consideration payable with respect thereto. Upon surrender of a Certificate for cancellation to the Paying Agent, together with a duly executed and completed letter of transmittal, the holder of such Certificate will be entitled to receive in exchange therefor the Merger Consideration for each share of Company Common Stock formerly represented by such Certificate, without interest and subject to deduction for any required withholding tax, and the Certificate so surrendered will forthwith be canceled.

As promptly as reasonably practicable following the Effective Time (and in any event not later than the third Business Day following the Effective Time), Parent will cause the Paying Agent to issue and deliver to each holder of uncertificated shares of Company Common Stock represented by book entry (“Book-Entry Shares”) a check or wire transfer for the amount of cash that such holder is entitled to receive in respect of such Book-Entry Shares, without such holder being required to deliver a certificate or an executed letter of transmittal to the Paying Agent, and such Book-Entry Shares will then be canceled. No interest will be paid or accrued for the benefit of holders of Book-Entry Shares on the Merger Consideration payable in respect thereof.

All cash paid upon the surrender for exchange or cancellation of Certificates that immediately prior to the Effective Time represented outstanding shares of Company Common Stock that were converted into the Merger Consideration with respect thereto or Book-Entry Shares in accordance with the terms of the Merger Agreement will be deemed to have been paid in full satisfaction of all rights pertaining to the shares of Company Common Stock formerly represented by such Certificates or Book-Entry Shares. At the Effective Time, the stock transfer books of DoubleVerify will be closed and there will be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Book-Entry Shares are presented to the Surviving Corporation or the Paying Agent for transfer or transfer is sought for Book-Entry Shares, such Certificates or Book-Entry Shares will be canceled and exchanged as provided in the Merger Agreement, subject to applicable law in the case of Dissenting Shares.

At any time following the date that is twelve (12) months after the Effective Time, Parent will be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) that have been made available to the Paying Agent and that have not been disbursed to holders of Certificates or Book-Entry Shares, and thereafter such holders (except to the extent representing Excluded Shares or Dissenting Shares) will be entitled to look to the Surviving Corporation (subject to abandoned property, escheat or other similar laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificates or Book-Entry Shares. The Surviving Corporation will pay all fees, costs, charges and expenses of the Paying Agent in connection with the exchange of shares of Company Common Stock for the Merger Consideration.

A “Material Adverse Effect” means any event, change, occurrence or effect that (x) individually or in the aggregate, has had, or would reasonably be expected to have a material adverse effect on the business, financial condition or results of operations of DoubleVerify and its subsidiaries, taken as a whole or (y) would, or would reasonably be expected to, prevent or materially impair or materially delay the ability of DoubleVerify to consummate the transactions; provided, that, solely for purposes of the foregoing clause (x), no event, change, occurrence or effect directly or indirectly arising out of, attributable to or resulting from any of the following, alone or in combination, will be deemed to constitute, or be taken into account in determining whether there has been or would or could be, a Material Adverse Effect:

any changes in general economic or business conditions or in the financial, debt, banking, capital, currency, credit or securities markets, or in interest or exchange rates, in each case, in the United States or elsewhere in the world,

any changes or developments generally affecting any of the industries in which the Company or its subsidiaries operate, including due to changes in applicable law or the issuance of any executive orders or other proposed or binding directives issued by any governmental entity or other governmental activity (including any imposition of new tariffs, duties, trade restrictions, or import/

TABLE OF CONTENTS

export regulations by a governmental entity or any retaliatory measures enacted in response thereto), in each case, after the date of the Merger Agreement;

any changes or proposed changes in GAAP or in applicable accounting regulations or principles, or in interpretations of any of the foregoing, in each case, after the date of the Merger Agreement;

any changes in political, geopolitical, legal, tax, or regulatory conditions, including any outbreak, continuation or escalation of any military conflict, declared or undeclared war, armed hostilities (including the war in Ukraine and the conflicts in the Middle East (including hostilities in Iran, Israel, the Palestinian territories, Yemen and southern Lebanon)), civil unrest, public demonstrations or acts of foreign or domestic terrorism, or any escalation or worsening of, or responses to, any such conditions, and any sanctions or other applicable laws, directives, policies, guidelines or recommendations promulgated by any governmental entity in connection therewith;

any change in the price or trading volume of the Company Common Stock, in and of itself; (provided, that the facts or occurrences giving rise to or contributing to such change that are not otherwise excluded from the definition of “Material Adverse Effect” in the Merger Agreement may be taken into account in determining whether there has been a Material Adverse Effect);

any failure by DoubleVerify and its subsidiaries to meet internal, published or analysts’ projections, forecasts or revenue or earnings predictions, in and of itself (provided, that the facts or occurrences giving rise to or contributing to such failure that are not otherwise excluded from the definition of “Material Adverse Effect” in the Merger Agreement may be taken into account in determining whether there has been a Material Adverse Effect);

any natural or manmade disasters or calamities, weather conditions including hurricanes, floods, tornadoes, tsunamis, earthquakes and wildfires, “acts of God”, regional, national or international cyber outages or other force majeure events, or any escalation or worsening of, or responses to, such conditions, global health conditions, including any epidemic, pandemic or outbreak of disease or public health event (including COVID-19, monkeypox and Ebola (or similar viruses)), or any escalation or worsening of such conditions;

any other regional, national or international calamity, crisis or emergency, including any government shutdown, default or other similar event or occurrence by or involving any governmental entity or any change in government funding, budgeting or fiscal policy, whether or not caused by any person;

the announcement, pendency or consummation of the Merger or the Transactions, the identity of the parties to the Merger Agreement or any facts or circumstances relating to Parent, Merger Sub or any of their affiliates (or any actions taken by Parent, Merger Sub or any of their affiliates or the announcement or other disclosure of such persons’ plans or intentions with respect to the conduct of the business of the Company or its subsidiaries after the Closing), including the initiation of litigation by any stockholder of the Company (or a derivative or similar claim) to the extent asserting allegations of breach of fiduciary duty or under securities laws relating to the Merger Agreement or the Transactions;

10.

any action taken (or not taken) by DoubleVerify or any of its subsidiaries, in each case which is expressly required to be taken (or not taken) by the Merger Agreement, including any inaction in compliance with the express provisions of the Merger Agreement; or

11.

any actions taken (or omitted to be taken) at the express written request or with the express written consent of Parent or Merger Sub.

In the case of clauses (1), (2), (3), (7), (8), and (9) only, to the extent the impact of such event, change, occurrence or effect has a materially disproportionately adverse effect on DoubleVerify and its subsidiaries, taken as a whole, as compared to other companies operating in the industries in which DoubleVerify and its subsidiaries conduct business, such event, change, occurrence or effect with regard to such clauses may be taken into account (solely to the extent of such disproportionate effect) when determining if a Material Adverse Effect has occurred.

“Acquisition Proposal” means any inquiry, proposal or offer from any person or group of persons other than Parent or one of its subsidiaries for (i) a merger, reorganization, consolidation, share exchange, business combination, recapitalization, liquidation, dissolution, share sale, disposition or similar transaction involving an acquisition of 20% or more of the business of the Company (or of any subsidiary or subsidiaries of the Company whose businesses constitute, or of assets of the Company and its subsidiaries that constitute, 20% or more of the assets of the Company and its subsidiaries, taken as a whole), in each case, measured by the fair market value thereof, (ii) the acquisition in any manner, directly or indirectly, of over 20% of the outstanding shares of Company Common Stock, (iii) a tender offer or exchange offer that if consummated would result in any person or Group (as defined in the Exchange Act) acquiring beneficial ownership of 20% or more of the outstanding shares of Company Common Stock, in each case other than the Transactions, or (iv) any combination of the foregoing.

“Superior Proposal” means a bona fide written Acquisition Proposal on terms which the Company Board or the Special Committee determines in good faith, after consultation with the Company’s outside legal counsel and financial advisors, (i) taking into account all legal, financial, regulatory, and other aspects of the Acquisition Proposal, the conditionality, timing and likelihood of consummation thereof, is reasonably likely to be consummated in accordance with its terms and (ii) if consummated to be more favorable from a financial point of view to the holders of shares of Company Common Stock than the Transactions (taking into account any revisions to the terms of the Merger Agreement, the Limited Guarantee and the Commitment Letters proposed by Parent in writing prior to the time of such determination in accordance with the terms and conditions of the Merger Agreement); provided that for purposes of the definition of “Superior Proposal,” the references to “20%” in the definition of Acquisition Proposal shall be deemed to be references to “50%”.

TABLE OF CONTENTS

The Company has agreed to, and has agreed to cause its subsidiaries and their respective directors and officers to, and to use commercially reasonable efforts to cause the other representatives of the Company and its subsidiaries to, immediately cease and cause to be terminated any existing activities, discussions and negotiations with any person with respect to any Acquisition Proposal or potential Acquisition Proposal and, within two (2) days following the date of the Merger Agreement, terminate all access granted to any such person and its representatives to any physical or electronic dataroom established in connection with a potential Acquisition Proposal, and, within three (3) days following the date of the Merger Agreement, request that all non-public information previously provided by or on behalf of DoubleVerify or any of its subsidiaries to such persons be returned or destroyed in accordance with the applicable confidentiality agreement with such person. DoubleVerify has also agreed not to release or permit the release of any person from, or to waive or permit the waiver or termination of, any standstill or similar provision of any agreement to which DoubleVerify or any of its subsidiaries is a party, other than to the extent the Company Board or any committee thereof determines in good faith, after consultation with outside legal counsel, that failing to provide such waiver, release or termination would reasonably be expected to be inconsistent with its fiduciary duties under applicable law. In addition, during the Interim Period, DoubleVerify has agreed not to, and has agreed to cause its subsidiaries and their respective officers, directors and employees not to, and has agreed to use commercially reasonable efforts to cause its other representatives not to, directly or indirectly:

•

initiate, seek, solicit or knowingly facilitate or encourage any discussions, inquiries, proposals or offers that constitute, or would reasonably be expected to lead to, an Acquisition Proposal;

•

other than as described below in accordance with the Merger Agreement, enter into, engage, continue or otherwise participate in any negotiations or discussions, provide or cause to be provided any non-public information or data relating to the Company or any of its subsidiaries, or afford access to the books or records or officers of the Company and its subsidiaries, in each case for the purpose of encouraging or knowingly facilitating the making, submission or announcement of any proposal or inquiry that constitutes, or would reasonably be expected to lead to, an Acquisition Proposal;

•

other than as described below in accordance with the Merger Agreement, enter into any Alternative Acquisition Agreement or enter into any agreement requiring the Company to abandon, terminate or fail to consummate the Transactions; and

•

endorse, approve or recommend any proposal that constitutes, or would reasonably be expected to lead to, an Acquisition Proposal.

At any time after the date of the Merger Agreement and prior to the receipt of the Required Company Stockholder Approval, if DoubleVerify receives an unsolicited bona fide written Acquisition Proposal that did not result from a breach in any material respect of the non-solicitation covenants in the Merger Agreement and the Company Board determines in good faith, after consultation with its financial advisors and outside legal counsel, (1) that such Acquisition Proposal constitutes or would reasonably be expected to lead to a Superior Proposal, and (2) that the failure to take such action would be inconsistent with the Company Board’s fiduciary duties under applicable law, then DoubleVerify may (i) furnish information (including non-public information with respect to the Company and its subsidiaries), and afford access to the books or records or officers of the Company and its subsidiaries, to the person making such Acquisition Proposal, pursuant to a customary confidentiality agreement; (ii) engage or participate in discussions or negotiations with such person or its representatives regarding such Acquisition Proposal; and (iii) otherwise facilitate and encourage such Acquisition Proposal; provided that, prior to, or substantially concurrently with, the time such information is provided to such person or its representatives, DoubleVerify shall, subject to applicable law and any applicable “clean team” or similar arrangement, provide or make available to Parent any non-public information concerning the Company or any of its subsidiaries that is provided to the person making such Acquisition Proposal or its representatives which was not previously made available to Parent.

For purposes of this proxy statement and the Merger Agreement, “Adverse Recommendation Change” means any of the following (other than causing or permitting DoubleVerify or any of its subsidiaries to enter into an Alternative Acquisition Agreement, which the Merger Agreement prohibits separately and which does not itself constitute an Adverse Recommendation Change):

•

•

failing to publicly reaffirm the recommendation of the Company Board within five (5) business days after Parent so requests in writing following the public disclosure of an Acquisition Proposal (other than a tender or exchange offer of the type described in the following bullet); however, DoubleVerify has no obligation to make such a reaffirmation on more than three (3) separate occasions as to any one Acquisition Proposal;

resolving or publicly proposing to take any action described in the foregoing.

For purposes of this proxy statement and the Merger Agreement, “Intervening Event” means an event, occurrence, fact, change or effect that is material to the business, assets or operations of the Company and (A) was not known to, or reasonably foreseeable by, the Company Board as of the date of the Merger Agreement (or if known or reasonably foreseeable, the magnitude or consequences of which were not known or reasonably foreseeable by the Company Board as of the date of the Merger Agreement), which event, occurrence, fact, change or effect, or any consequence thereof, first becomes known to, or reasonably foreseeable by, the Company Board prior to the Effective Time, and (B) does not relate to (i) an Acquisition Proposal, (ii) the mere fact, in and of itself, that the Company meets or exceeds any internal or published projections, forecasts, estimates or predictions of revenue, earnings or other financial or operating metrics for any period ending on or after the date hereof (it being understood that the underlying cause of any of the foregoing in this clause (ii) may be considered and taken into account to the extent not otherwise expressly prohibited by this definition), (iii) any changes in the market price or trading volume of the Company’s capital stock or the credit rating of the Company (it being understood that the underlying cause of any of the foregoing in this clause (iii) may be considered and taken into account to the extent not otherwise expressly prohibited by this definition), or (iv) changes in general economic, political or financial conditions or markets (including changes in interest rates, exchange rates, stock, bond or debt prices).

Notwithstanding anything to the contrary in the Merger Agreement:

•

The Company may (1) terminate the Merger Agreement to enter into an Alternative Acquisition Agreement or (2) make an Adverse Recommendation Change if:

•

The Company receives an unsolicited bona fide written Acquisition Proposal that did not result from a breach in any material respect of the non-solicitation covenants in the Merger Agreement

101

TABLE OF CONTENTS

and the Company Board or any committee of the Company Board (including the Special Committee) determines in good faith, after consultation with its financial advisors and outside legal counsel that (x) such Acquisition Proposal constitutes a Superior Proposal and (y) the failure to take such action would reasonably be expected to be inconsistent with its fiduciary duties under applicable law,

•

The Company provides Parent four (4) business days’ prior written notice of its intention to take such action, which notice will include the information with respect to such Superior Proposal that is specified in the Merger Agreement and, if the alternative acquiror amends the financial terms or any other material term or condition of the Superior Proposal, DoubleVerify must deliver a new notice to Parent and an additional three (3) business day period will run from Parent’s receipt of that new notice,

•

during the applicable period described in the item directly above (subject to any applicable extensions), DoubleVerify considers and discusses with Parent in good faith to propose any adjustments or modifications to the terms of the Merger Agreement such that the Acquisition Proposal ceases to be a Superior Proposal, and

•

at the end of the four (4) business day notice period, the Company Board again makes the determination in good faith, after consultation with its outside legal counsel and financial advisors (and after taking into account any adjustments or modifications proposed in writing by Parent during the notice period), that the Acquisition Proposal continues to be a Superior Proposal;

•

in response to an Intervening Event, and if the Company Board (or any committee thereof) determines in good faith, after consultation with DoubleVerify’s outside legal counsel and financial advisors, that the failure to do so would be inconsistent with the directors’ fiduciary duties under applicable law, the Company Board may make an Adverse Recommendation Change if (i) DoubleVerify provides Parent four (4) business days’ prior written notice of its intention to take such action, which notice will (a) set forth in reasonable detail information describing the Intervening Event and (b) state that the Company Board or any Company Committee has determined to make an Adverse Recommendation Change, (ii) prior to making such Adverse Recommendation Change, to the extent Parent has made a request in writing to the Company to engage, DoubleVerify negotiates and engages in good faith with Parent, and causes its directors, officers and employees to have, and instructs and uses commercially reasonable efforts to cause its other Representatives to have, negotiated and engaged in good faith with Parent, during such four (4) business day period (subject to applicable extensions) to consider any adjustments proposed by Parent to the terms and conditions of the Merger Agreement such that the failure to make an Adverse Recommendation Change in response to the Intervening Event would no longer be inconsistent with the Company Board’s fiduciary duties under applicable law, and (iii) at the end of the four (4) business day period described in clause (i) above, the Company Board determines in good faith after consultation with its financial advisors and outside legal counsel (after taking into account any revised terms proposed in writing by Parent) that the failure to make an Adverse Recommendation Change would be inconsistent with its fiduciary duties under applicable law; and

•

nothing contained in the Merger Agreement prohibits the Company, the Company Board or any committee of the Company Board (including the Special Committee) from (1) disclosing to the stockholders of the Company any “stop, look and listen” communication pursuant to Rule 14d-9(f) promulgated under the Exchange Act; (2) taking and disclosing to stockholders of DoubleVerify a position contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act or (3) making any required disclosure to the DoubleVerify Stockholders if the Company Board or any committee of the Company Board (“Company Committee”) (including the Special Committee) determines that the failure to make such statement would be inconsistent with its fiduciary duties under, or violate, applicable law.

Employee Matters

Terms of Compensation and Benefits Continuation

Parent has agreed to cause the Surviving Corporation and each of its subsidiaries to maintain for each current or former employee of the Company or any of its subsidiaries (each, a “Company Employee”), without

102

TABLE OF CONTENTS

limiting any additional rights that a Company Employee has under a Company benefit plan, applicable law, or a written agreement with Parent or one of its affiliates, the following compensation and benefits, for a period commencing at the Effective Time and ending on the first anniversary thereof (or such earlier date of the Company Employee’s termination of employment), (1) cash compensation levels (such term to include salary, base wage rate, target bonus opportunities, commission opportunities, and severance, but not to include retention, transaction, or change in control compensation) that are each no less favorable than those provided or made available to such Company Employee, or to which such Company Employee had a legally binding right (whether or not subject to any conditions) as of immediately prior to the Effective Time, and (2) employee benefits (excluding defined benefit plans, retiree welfare arrangements, deferred compensation, equity and equity-based compensation, long term incentives, and retention, transaction, and change in control compensation) that are in the aggregate no less favorable than the employee benefits provided to similarly situated employees of Parent and its subsidiaries.

Parent has also agreed to give each Company Employee full credit for purposes of determining eligibility, vesting, and benefit accrual (other than benefit accruals under defined benefit pension plans) under each employee benefit plan, program, policy, and arrangement, excluding any retiree welfare arrangement or incentive compensation plan, maintained as of and after the Effective Time by Parent, any of its subsidiaries, including the Surviving Corporation (each, a “Parent Plan”), for such Company Employee’s prior service to the Company, its subsidiaries, and their predecessor entities to the same extent recognized by the Company and its subsidiaries under the comparable benefit plan of the Company immediately prior to the Effective Time, except if such credit would result in the duplication of benefits or if similarly situated employees of Parent and its subsidiaries do not receive credit or are grandfathered or frozen. With respect to each Parent Plan that is a “welfare benefit plan” (as defined in Section 3(1) of ERISA), Parent has agreed to use commercially reasonable efforts to (1) cause there to be waived any pre-existing condition or eligibility limitations and (2) give effect, in determining any deductible and maximum out-of-pocket limitations, to claims incurred and amounts paid by, and amounts reimbursed to, the applicable Company Employee for the plan year in which Effective Time occurs under similar plans maintained by the Company and its subsidiaries immediately prior to the Effective Time during the applicable plan year as if such claim was incurred under or amount was paid or reimbursed by such Parent Plan.

With respect to the Company’s fiscal year in which the Closing occurs, Parent has agreed to pay, pursuant to each Company benefit plan that is a bonus or incentive plan (the “Bonus Plans”), a bonus to each Company Employee who is a Bonus Plan participant that is equal to the greater of (x) 100% of such Company Employee’s target bonus for such year and (y) such Company Employee’s actual bonus earned for such fiscal year, in accordance with the applicable Bonus Plan, in either case at such time as bonuses paid under the Bonus Plans are paid in the ordinary course of business, consistent with past practice.

The Merger Agreement provides that the Company ESPP will terminate no later than immediately prior to the Effective Time. No new offering period will commence under the Company ESPP on or after the date of the Merger Agreement, no individual who is not participating in the Company ESPP as of such date may commence participation therein, and no participant may increase such participant’s rate of payroll contributions from the rate in effect as of the date of the Merger Agreement. Any outstanding offering period will be shortened so that a purchase date will occur on or prior to the date that is five (5) business days prior to the anticipated Closing Date, and each participant’s accumulated payroll contributions will be used to purchase shares of Company Common Stock in accordance with the terms of the Company ESPP on such purchase date, with any remaining amounts refunded to participants as soon as practicable.

The Merger Agreement also provides that if Parent requests in writing at least ten (10) business days prior to the Closing Date, the Company will deliver or cause to be delivered to Parent duly adopted resolutions terminating each Company benefit plan intended to be qualified under Section 401(a) of the Code (the “401(k) Plan”), amending the 401(k) Plan as necessary to bring it up to date with all applicable legally required plan amendments, and fully vesting all participants under the 401(k) Plan, in each case effective no later than the business day preceding the Closing Date.

General Efforts

Upon the terms and subject to the conditions set forth in the Merger Agreement and subject to any different standard set forth in the Merger Agreement with respect to any covenant or obligation, Parent and

103

TABLE OF CONTENTS

Merger Sub will (and will cause their respective affiliates to, if applicable), on the one hand, and DoubleVerify will (and will cause its subsidiaries to), on the other hand, use their respective commercially reasonable efforts to (1) take (or cause to be taken) all actions; (2) do (or cause to be done) all things; and (3) assist and cooperate with the other parties to the Merger Agreement in doing (or causing to be done) all things, in each case as are necessary, proper or advisable to consummate and make effective, as promptly as reasonably practicable, the Merger and the other Transactions, including by (A) causing the conditions to the Merger of the other party to the Merger Agreement to be satisfied (but not waived) and (B) (i) obtaining all consents, waivers, approvals, orders and authorizations from governmental entities and (ii) making all registrations, declarations and filings with governmental entities, in each case that are necessary or advisable to consummate the Transactions. DoubleVerify and Parent will use commercially reasonable efforts to promptly notify each other of (x) any notice or communication received from any government entity in connection with the Merger or from any person alleging in writing that such person’s consent is or may be required in connection with the Merger, (y) any action, claim or proceeding commenced or, to DoubleVerify or Parent’s knowledge, threatened in writing against, relating to or involving DoubleVerify, Parent or any of their respective subsidiaries which relates to the Merger, or (z) any effect, occurrence, change or event that has caused, or would reasonably be expected to cause, any of the conditions set forth in the Merger Agreement not to be satisfied.

Indemnification and Insurance

Except as may be required by applicable law, all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time and rights to advancement of expenses relating thereto existing at the time of the signing of the Merger Agreement in favor of any Indemnified Party as provided in DoubleVerify’s organizational documents and its subsidiaries’ organizational documents or in any indemnification agreement between such Indemnified Party and DoubleVerify or any of its subsidiaries made available to Parent prior to the date of the Merger Agreement will survive the Merger and continue in full force and effect, will not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party and by operation of law will be assumed by the Surviving Corporation in the Merger, without further action, at the Effective Time.

For a period of six (6) years from the Effective Time, Parent will, at its sole election, cause the Surviving Corporation to (i) maintain in effect the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by DoubleVerify and its subsidiaries as of the signing of the Merger Agreement, (ii) cause to be provided substitute policies or (iii) purchase a “tail policy,” in each case of at least the same coverage and amounts and containing other terms and conditions that are not less advantageous in the aggregate than the directors’ and officers’ liability coverage and fiduciary liability insurance currently maintained by DoubleVerify and its subsidiaries with respect to claims arising from facts or events that occurred at or before the Effective Time (with insurance carrier having at least an “A” rating by A.M. Best with respect to directors’ and officers’ liability insurance); provided, that after the Effective Time, the Surviving Corporation will not be required to pay with respect to such insurance policies in respect of any one policy year annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date of the Merger Agreement in respect of the coverage required to be obtained, but in such case will purchase as much coverage as reasonably practicable for such maximum amount; provided, further, that if the Surviving Corporation elects to purchase an insurance policy and the annual coverage thereunder costs more than 300% of such last annual premium, the Surviving Corporation will purchase the maximum amount of annual coverage obtainable for 300% of such last annual premium.

In the event that the Surviving Corporation or Parent or any of their respective successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers, conveys or disposes of all or a majority of its properties and assets to any person or engages in any division transaction, then, and in each such case, proper provision will be made so that the successors and assigns of the Surviving Corporation or Parent, as the case may be, will succeed to the indemnification, exculpation and insurance obligations described above.

The indemnification provided for in the Merger Agreement is not deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to law, contract or otherwise.

TABLE OF CONTENTS

Antitrust

Under the Merger Agreement, each of DoubleVerify, Parent, and Merger Sub has agreed to use its respective reasonable best efforts to take, or cause to be taken, all actions and to do, or cause to be done, and cooperate with each other in order to do, all things reasonably necessary, proper or advisable under all applicable Antitrust Laws and foreign investment laws to consummate the Transactions at the earliest practicable date (and in any event no later than the Termination Date), including (i) causing the preparation and filing as promptly as reasonably practicable of all forms, registrations and notices required to be filed to consummate the Merger and the other Transactions and the taking of such actions as are reasonably necessary to obtain any requisite consent or expiration of any applicable waiting period under any Antitrust Laws or foreign investment laws; (ii) using reasonable best efforts to defend all actions, suits or proceedings, (including by appeal if necessary), whether judicial or administrative, by or before any governmental entity challenging the Merger Agreement or the consummation of the Transactions; and (iii) using reasonable best efforts to resolve any objection asserted with respect to the Transactions under any Antitrust Law or foreign investment laws and to prevent the entry of any court order, and to have vacated, lifted, reversed or overturned any injunction, decree, ruling, order or other action, whether temporary, preliminary or permanent, of any governmental entity that would prevent, prohibit, restrict, interfere with, hinder or delay the consummation of the Transactions.

In furtherance and not in limitation of the covenants described above, DoubleVerify and Parent have agreed to (i) prepare and file as promptly as practicable (and in any event no later than ten (10) business days from the date of the Merger Agreement) an appropriate filing of a Notification and Report Form pursuant to the HSR Act with respect to the Transactions, which form shall specifically request early termination of the waiting period prescribed by the HSR Act, and (ii) prepare and file as promptly as practicable appropriate filings (and in any event no later than twenty (20) business days from the date of the Merger Agreement and in draft form, where applicable) under the Antitrust Laws and competition laws in Australia, Cyprus, Germany and Morocco. Parent will pay all filing fees and other charges for the filings required under the Antitrust Laws and foreign investment laws by DoubleVerify and Parent.

The obligations of Parent and Merger Sub under the regulatory provisions of the Merger Agreement include Parent and Merger Sub using their respective reasonable best efforts in committing to (and causing their respective subsidiaries to commit to): (i) entering into any settlement, undertaking, consent decree, stipulation or agreement with or required by any governmental entity in connection with the Transactions; (ii) selling, divesting, or otherwise conveying any asset, category, portion or part of an asset or business of DoubleVerify and its subsidiaries, contemporaneously with or subsequent to the Effective Time; (iii) permitting DoubleVerify and its subsidiaries to sell, divest, or otherwise convey any of the particular assets, categories, portions or parts of assets or businesses of DoubleVerify and its subsidiaries prior to the Effective Time; (iv) licensing, holding separate or entering into similar arrangements or conduct restrictions with respect to its respective assets or the assets of DoubleVerify and its subsidiaries or the conduct of business arrangements or terminating any existing relationships and contractual rights and obligations; (v) obtaining prior approval or other approval from a governmental entity, or submitting a notification or otherwise notifying any governmental entity, prior to consummating any future transaction (other than the Transactions) as a condition to obtaining any and all expirations of waiting periods under the HSR Act (or other Antitrust Laws or foreign investment laws) or consents from any governmental entity necessary to consummate the Transactions; and (vi) otherwise taking, or committing to take, actions after the Effective Time that are purely administrative in nature.

However, neither Parent, on the one hand, nor DoubleVerify and its subsidiaries, on the other hand, will be obligated to take any such actions (A) unless the taking of such action is conditioned upon the occurrence of the Effective Time, (B) if such action would reasonably be expected to have a material adverse effect on the value of the Transactions to Parent, or (C) if such action would reasonably be expected to materially and adversely impact the day-to-day business of Parent and its subsidiaries (including the offering, selling, licensing, marketing, promoting or use of any products or services of Parent and its subsidiaries) as conducted as of the date of the Merger Agreement (any such action described in clauses (B) or (C), a “Remedial Restriction”). In addition, other than any actions that are purely administrative in nature, in no event will Parent be obligated to take, or commit to take, any actions that limit Parent’s freedom of action with respect to, or its ability to retain or exercise rights of ownership or control with respect to, entities, businesses, divisions,

105

TABLE OF CONTENTS

operations, products or product lines, assets, intellectual property or businesses of Parent and its subsidiaries, other than, after the Effective Time, DoubleVerify and its subsidiaries.

Notwithstanding the foregoing, Parent and DoubleVerify will jointly develop and direct all matters with any governmental entity consistent with their respective obligations described above and will jointly devise and implement in good faith the strategy for obtaining any necessary antitrust or competition consents, registrations, approvals and clearances under any Antitrust Law or foreign investment law relating to the Transactions. In the event of any disagreement or dispute between Parent and DoubleVerify relating to the strategy or appropriate course of action or content of any submission or filing made in connection with obtaining antitrust or competition consents, registrations, approvals and clearances under any Antitrust Laws or foreign investment laws, each of Parent and DoubleVerify will escalate such disagreement or dispute to the Chief Executive Officer of Parent and the Chief Executive Officer of DoubleVerify for resolution. Each of Parent and DoubleVerify will direct their respective Chief Executive Officers to cooperate with one another and to work in good faith to resolve such dispute as promptly as reasonably practicable. If such dispute is not resolved on or prior to the date that is five (5) business days following the date on which such matter was referred to each Chief Executive Officer, subject to the other terms and conditions of the regulatory provisions of the Merger Agreement, Parent will have the right to make the final determination with respect to such matter.

Financing Covenant; Company Cooperation

Parent and Merger Sub will use commercially reasonable efforts to take all actions and do all things reasonably necessary or advisable to arrange and obtain the Financing in the Required Amount and to consummate the Financing on or prior to the Closing. Parent and Merger Sub will not, without the prior written consent of DoubleVerify, amend, modify, supplement or replace the Equity Commitment Letter, the Debt Commitment Letter or any Debt Financing document, except for certain permitted amendments to the Debt Commitment Letter and Debt Financing documents that would not reasonably be expected to impose new or additional conditions precedent to the funding of the Debt Financing, reduce the net cash amount of the Debt Financing below the Required Amount, materially impair, delay or prevent the consummation of the Financing on the Closing, or adversely affect Parent’s or Merger Sub’s ability to consummate the Transactions. Parent and Merger Sub expressly acknowledge and agree that their obligations under the Merger Agreement, including their obligation to consummate the Merger, are not subject to, or conditioned on, Parent’s or Merger Sub’s receipt of financing.

Parent and Merger Sub will give DoubleVerify prompt (but in any event within two (2) business days) written notice of any material breach, default, cancellation, termination or repudiation by any party to the Commitment Letters or any agreements or documents relating to the Financing of which Parent or its affiliates becomes aware. If all or any portion of the Financing becomes unavailable on the terms, in the manner, or from the sources contemplated by the Commitment Letters, Parent and Merger Sub will (i) promptly (but in any event within two (2) business days) notify DoubleVerify in writing thereof and the reasons therefor, (ii) use commercially reasonable efforts to obtain, arrange and consummate alternative financing from alternative sources (on terms containing no new, additional or more onerous conditions relative to the financing conditions or any other prohibited modifications) in an amount that, together with any remaining committed Debt Financing and unrestricted cash immediately available to Parent for purposes of funding the Required Amount, is at least equal to the Required Amount, and (iii) use commercially reasonable efforts to obtain, and when obtained, provide DoubleVerify with a copy of, new financing commitments that provide for such alternative financing. Upon request of DoubleVerify, Parent and Merger Sub will keep DoubleVerify informed in reasonable detail of the status of Parent’s and Merger Sub’s efforts to obtain the Financing and to satisfy the conditions thereof.

To the extent reasonably requested by Parent, DoubleVerify will, and will cause its subsidiaries and its and their respective representatives to, use commercially reasonable efforts to provide cooperation in connection with the arrangement of the Debt Financing as is customarily provided for issuers in financings of the type contemplated by the Debt Commitment Letter (provided that such requested cooperation does not unreasonably interfere with the business or operations of DoubleVerify and its subsidiaries). Such cooperation includes, among other things, using commercially reasonable efforts to:

•

furnish to Parent financial information as required by the Merger Agreement;

106

TABLE OF CONTENTS

•

cause appropriate members of senior management of DoubleVerify to participate in a reasonable number of meetings, due diligence sessions and presentations at reasonable times and with reasonable advance notice;

•

provide, at least three (3) business days prior to the Closing, documentation and other information required by the financing sources under applicable “know-your-customer” and anti-money laundering rules and regulations, including the USA PATRIOT Act;

•

provide reasonable and customary assistance with the preparation of pro forma financial information to the extent customary to be included in marketing materials or offering documents;

•

provide reasonable and customary assistance in the preparation of customary offering documents, syndication memoranda, ratings agency presentations and other marketing material for the Debt Financing, including the execution and delivery of customary authorization letters;

•

cooperate with Parent to obtain customary corporate and facilities credit ratings and cooperate with the financing sources’ due diligence;

•

assist in the preparation and negotiation, and in the execution and delivery at Closing, of the Debt Financing documents, including assistance with the preparation of schedules and exhibits thereto, and otherwise assist in facilitating the creation and perfection of security interests in the collateral contemplated by the Debt Financing; and

•

facilitate customary cooperation and assistance of DoubleVerify’s independent auditors to provide customary “comfort” letters (including “negative assurance” and change period comfort) and, if reasonably necessary, attend accounting diligence sessions.

DoubleVerify will also have the right to review and comment on marketing materials used in connection with the arrangement of the Debt Financing prior to the dissemination of such materials to potential lenders or other counterparties. Any failure of DoubleVerify to comply with its financing cooperation obligations will be disregarded for purposes of the condition precedent set forth in the Merger Agreement, unless the Debt Financing has not been obtained primarily as a result of DoubleVerify’s willful breach of such obligations. Obtaining the Debt Financing is not a condition to the consummation of the Merger.

Notwithstanding anything to the contrary in the Merger Agreement, neither DoubleVerify nor any of its subsidiaries will:

•

be required to incur any liability or make any payment prior to the Closing, other than liabilities and payments subject to reimbursement and indemnification by Parent;

•

be required to agree to make any payment, give any indemnity or otherwise commit to take any action that would be effective prior to the Closing;

•

be required to take any action that would jeopardize any attorney-client or other legal privilege, violate its organizational documents or applicable law, result in the creation of any liens on its assets prior to the Closing, or conflict with the terms of the Merger Agreement;

•

be required to provide or prepare any pro forma financial information, projections or other forward-looking financial information, or to prepare any financial statements or provide any financial information not readily available or historically prepared in the ordinary course of business; or

•

be required to execute or deliver any certificate, legal opinion, agreement or document relating to the Debt Financing that would be effective prior to the Closing (other than customary authorization letters and customary representation letters in connection with the marketing efforts for the Debt Financing).

Parent will indemnify and hold harmless DoubleVerify and its subsidiaries and their respective directors, officers, employees, agents and other representatives from and against any liabilities, costs or expenses (including reasonable legal fees and expenses) incurred in connection with the arrangement of the Debt Financing, except to the extent that such losses arise out of or result from any material inaccuracy in historical information provided by or on behalf of DoubleVerify or the gross negligence, bad faith, willful misconduct, fraud or intentional misrepresentation of DoubleVerify or any of its representatives. Parent, Merger Sub and their respective representatives will be required to keep all information received pursuant to the cooperation

107

TABLE OF CONTENTS

provisions confidential in accordance with the confidentiality agreement entered into between Parent and DoubleVerify. Following the earlier of the Effective Time or the termination of the Merger Agreement, Parent will promptly reimburse DoubleVerify for any reasonable and documented out-of-pocket third-party costs and expenses incurred in connection with the Debt Financing.

Treatment of Company Indebtedness

DoubleVerify will, and will cause its subsidiaries to, deliver all notices and take all other actions reasonably requested by Parent that are required to terminate all commitments outstanding under and repay in full all obligations, if any, owing in respect to the Credit Agreement (as defined below). Further, DoubleVerify will facilitate the release of all liens, if any, securing obligations with respect to the Credit Agreement. In connection with its obligations with respect to the Credit Agreement, DoubleVerify has agreed to use commercially reasonable efforts to (1) deliver to Parent the final payoff letter with respect to the Credit Agreement at least one (1) business day prior to the Closing Date (with drafts, including final payoff numbers, to be provided at least three (3) business days prior to the Closing Date) and (2) reasonably cooperate with any back-stop, “rollover” or termination of any existing letters of credit under the Credit Agreement; provided that, the parties acknowledge and agree that Parent shall be responsible for paying all amounts under the payoff letter, including by cash collateralizing, backstopping or repaying any letters of credit or similar obligations. Contemporaneously with the Closing, Parent and Merger Sub shall pay (or cause to be paid) to the lenders under the Credit Agreement the amount specified in the payoff letter (including after giving effect to any per diem amount specified therein, to the extent applicable) in cash in immediately available funds to the bank account(s) specified therein to discharge all liabilities and obligations of DoubleVerify and its subsidiaries outstanding under the Credit Agreement (including the release and discharge of all related guarantees, liens and security interests) and to terminate the commitments thereunder. The “Credit Agreement” means the Credit Agreement, dated August 12, 2024, by and among DoubleVerify, as borrower, DoubleVerify Midco, Inc. as guarantor, the lenders party thereto and JPMorgan Chase Bank, N.A., as administrative agent (as the same may be further amended, restated, amended and restated, supplemented or otherwise modified from time to time).

Transaction Litigation

DoubleVerify will use commercially reasonable efforts to prevent the entry of (and, if entered, to have vacated, lifted, reversed or overturned) any injunction, order, ruling, decree, judgment or similar order that results from any action against DoubleVerify or any of its directors by any DoubleVerify Stockholder arising out of or relating to the Merger Agreement or the Transactions (“Transaction Litigation”). DoubleVerify will (a) provide Parent with prompt notice of, and copies of all pleadings and correspondence relating to, any Transaction Litigation and (b) give Parent the opportunity to participate in (but not direct or control) the defense, settlement or compromise of any Transaction Litigation. Prior to the Effective Time, DoubleVerify will not, without the prior consent of Parent (such consent not to be unreasonably withheld, conditioned or delayed), make any payment with respect to, or compromise or settle or offer to settle, any Transaction Litigation.

Preparation of Proxy Statement and Special Meeting

As promptly as reasonably practicable following the date of the Merger Agreement (and in any event no later than twenty-five (25) business days after the date of the Merger Agreement, unless otherwise agreed by Parent), DoubleVerify will prepare and cause to be filed with the SEC a proxy statement in preliminary form, as required by the Exchange Act, relating to the Special Meeting. Except as described below, the proxy statement will include the Company Board’s recommendation with respect to the Merger. DoubleVerify will promptly notify Parent upon the receipt of any comments from the SEC or any request from the SEC for amendments or supplements to the proxy statement, and will promptly provide Parent with copies of all written correspondence between DoubleVerify and its representatives, on the one hand, and the SEC, on the other hand, with respect to the proxy statement. Each of DoubleVerify, Parent and Merger Sub will use its respective commercially reasonable efforts to respond promptly to any comments or requests from the SEC with respect to the proxy statement. DoubleVerify will use its commercially reasonable efforts so that the proxy statement will comply as to form in all material respects with the provisions of the Exchange Act and the rules and regulations promulgated thereunder.

108

TABLE OF CONTENTS

Prior to filing or mailing the proxy statement (or any amendment or supplement thereto) or responding to any comments or requests from the SEC with respect thereto, to the extent permitted by applicable law, DoubleVerify will provide Parent a reasonable opportunity to review and to propose comments on such document or response, and DoubleVerify will consider in good faith the inclusion or reflection of any such reasonable comments so provided.

Parent and Merger Sub will (i) as promptly as possible, furnish to DoubleVerify all information concerning Parent and Merger Sub that is required to be included in the proxy statement by the Exchange Act and the rules and regulations promulgated thereunder, that is customarily included in proxy statements prepared in connection with transactions of the type contemplated by the Merger Agreement, as otherwise required by applicable law or requested by the SEC, or that may be reasonably requested by DoubleVerify in connection with the proxy statement, and (ii) will otherwise use commercially reasonable efforts to assist and cooperate with DoubleVerify and its representatives in the preparation of the proxy statement and the resolution of comments from the SEC.

If at any time prior to the Effective Time, any event or circumstance relating to DoubleVerify, Parent or Merger Sub or any of their respective subsidiaries, or their respective officers or directors, is discovered by DoubleVerify or Parent, respectively, which, pursuant to the Exchange Act, should be set forth in an amendment or a supplement to the proxy statement so that such document would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they are made, not misleading, such party will promptly inform the others. Each of Parent, Merger Sub and DoubleVerify will correct any information provided by it for use in the proxy statement which has become false or misleading.

In accordance with DoubleVerify’s organizational documents, unless the Merger Agreement is validly terminated, DoubleVerify will use commercially reasonable efforts to, as promptly as reasonably practicable after the date of the Merger Agreement, (x) establish a record date for and give notice of the Special Meeting and (y) mail the proxy statement to the holders of Company Common Stock as of the close of business on the record date established for the Special Meeting. Without the prior written consent of Parent (not to be unreasonably withheld, conditioned or delayed), in no event will the record date be changed to such a date that would result in the Special Meeting being within ten (10) business days of the Initial Termination Date, except as required by applicable law.

Without the prior written consent of Parent, the adoption of the Merger Agreement will be the only matter (other than matters of procedure and matters required by applicable law to be voted on by DoubleVerify Stockholders in connection with the adoption of the Merger Agreement, including the advisory vote regarding merger-related compensation and a customary proposal regarding adjournment of the Special Meeting) that DoubleVerify will propose to be acted on by DoubleVerify Stockholders at the Special Meeting.

DoubleVerify will use commercially reasonable efforts to duly call, convene and hold the Special Meeting as promptly as reasonably practicable after the mailing of the proxy statement (with the Special Meeting in no event being initially scheduled for a date later than the 45th calendar day following the first mailing of the definitive proxy statement to DoubleVerify Stockholders). DoubleVerify may postpone, recess, reschedule or adjourn the Special Meeting: (i) with the consent of Parent (not to be unreasonably withheld, conditioned or delayed), (ii) for the absence of a quorum (provided that DoubleVerify may not postpone or adjourn the Special Meeting more than two (2) times pursuant to this clause or for more than ten (10) business days in the aggregate, in each case, without Parent’s prior written consent), (iii) to solicit additional proxies for the purposes of obtaining the Required Company Stockholder Approval (provided that DoubleVerify may not postpone or adjourn the Special Meeting more than two (2) times pursuant to this clause or for more than ten (10) business days in the aggregate, in each case, without Parent’s prior written consent), (iv) to allow reasonable additional time for the filing and distribution of any supplement or amendment to the proxy statement which the Company Board has determined in good faith (after consultation with its outside legal counsel) is necessary under applicable laws and for such supplemental or amended disclosure to be disseminated to and reviewed by DoubleVerify Stockholders prior to the Special Meeting, and (v) if determined in good faith by the Company Board, after consultation with its legal counsel, such adjournment, recess, delay or postponement is required under applicable law or is reasonably necessary to comply with a request from the SEC or its staff.

109

TABLE OF CONTENTS

Unless the Company Board has effected an Adverse Recommendation Change, (x) on no more than two (2) occasions and prior to the vote having been taken, if DoubleVerify has not received proxies sufficient to obtain the Required Company Stockholder Approval, then Parent will have the right to require an adjournment or postponement of the Special Meeting for the purpose of soliciting additional votes in favor of the Merger Agreement, provided that no such individual adjournment or postponement will delay the Special Meeting by more than seven (7) days from the prior-scheduled date or to a date on or after the fifth business day preceding the Initial Termination Date, and (y) DoubleVerify will use its commercially reasonable efforts to solicit proxies in favor of the adoption of the Merger Agreement. Notwithstanding anything to the contrary and notwithstanding any Adverse Recommendation Change, DoubleVerify will submit the Merger Agreement to DoubleVerify Stockholders for adoption at the Special Meeting, provided that such obligation will immediately and automatically terminate and DoubleVerify will not be required to hold the Special Meeting if the Merger Agreement is terminated in accordance with its terms.

TABLE OF CONTENTS

three (3) business days prior to the termination of the Merger Agreement (or in the case of termination by DoubleVerify for failure to obtain the Required Company Stockholder Approval, prior to the Special Meeting) and (y) within one (1) year after such termination, DoubleVerify enters into a definitive agreement with respect to an Acquisition Proposal that is subsequently consummated (for this purpose, the references to “20% or more” in the definition of Acquisition Proposal are deemed to be references to “more than 50%”);

•

Parent terminates the Merger Agreement because the Company Board effects an Adverse Recommendation Change; or

•

The Company terminates the Merger Agreement in connection with entry into an Alternative Acquisition Agreement providing for a Superior Proposal.

In the following circumstances, Parent will pay to the Company the Parent Termination Fee:

DoubleVerify terminates the Merger Agreement (A) because Parent or Merger Sub has breached, or there is any inaccuracy in, any of its representations or warranties, or has breached or failed to perform any of its covenants or agreements, set forth in the Merger Agreement, which inaccuracy, breach or failure to perform would result in a failure of certain conditions to DoubleVerify’s obligations to close to be satisfied and is either not capable of being cured on or prior to the Termination Date, or, if capable of being cured, has not been cured on or prior to the earlier of (x) thirty (30) days following written notice from DoubleVerify to Parent and (y) five (5) business days prior to the Termination Date (but only if at the time of such termination DoubleVerify would not be prohibited from terminating the Merger Agreement as a result of being in material breach of any of its own representations, warranties, covenants or agreements), or (B) because (1) all of the conditions to Parent’s and Merger Sub’s obligations to close have been satisfied or waived (other than those conditions that by their nature are to be satisfied by actions taken at the Closing, which are capable of being satisfied at the Closing), (2) DoubleVerify has delivered irrevocable written notice to Parent irrevocably confirming that (x) all of the conditions to DoubleVerify’s obligations to close have been satisfied or irrevocably waived (other than those conditions that by their nature are to be satisfied by actions taken at the Closing, which are capable of being satisfied at the Closing) and (y) DoubleVerify stands ready, willing and able to consummate the Closing throughout the applicable three (3) business day period, and (3) Parent fails to consummate the Closing on or prior to the later of (x) three (3) business days following delivery of such written notification and (y) the date that is three (3) business days after the date on which the Closing is otherwise required to occur pursuant to the Merger Agreement; or

•

DoubleVerify or Parent terminates the Merger Agreement because the Merger has not been consummated by the Termination Date, and at the time of such termination DoubleVerify could have terminated the Merger Agreement pursuant to either of the termination rights described above.

If the Merger Agreement is validly terminated and prior to such termination there has been a willful breach of the Merger Agreement by any party, then notwithstanding payment of any Company Termination Fee or Parent Termination Fee the non-breaching party is also entitled to seek payment of damages, provided that in no event will such payment exceed an amount equal to (x) $175,000,000 plus (y) the amount of any recovery costs; plus (z) if Parent willfully breaches, then the amount of any reimbursement and indemnification obligations of Parent required under the debt financing cooperation covenant of the Merger Agreement. Any Company Termination Fee, Parent Termination Fee or recovery costs actually paid by the breaching party will be credited against, and will reduce on a dollar-for-dollar basis, the amounts payable by that party, up to that limitation. In no event will recovery costs payable by Parent or DoubleVerify, as applicable, exceed $7,500,000, respectively.

Amendment and Waiver

The Merger Agreement may be amended, modified or supplemented by the parties thereto, prior to the Effective Time and whether before or after the Required Company Stockholder Approval has been obtained, by action taken or authorized by their respective boards of directors; provided, however, that after the Required Company Stockholder Approval has been obtained, no amendment may be made that, pursuant to applicable law, requires approval or adoption by the DoubleVerify Stockholders without such approval or

113

TABLE OF CONTENTS

adoption. The Merger Agreement provides that the lenders and other parties providing the Debt Financing that Parent intends to use to fund a portion of the Merger Consideration, together with their respective affiliates and representatives (collectively, the “Financing Parties”), will not have any liability to DoubleVerify, its stockholders or any other person in connection with the Transactions (other than any claims Parent may have under the Debt Commitment Letter). The parties to the Merger Agreement have agreed to waive any claims against the Financing Parties. In the event that the Debt Financing is not funded and, as a result, the Merger is not consummated, the sole remedy available to DoubleVerify, its stockholders and their respective affiliates will be the Parent Termination Fee and reimbursement of costs and expenses required to be paid or reimbursed by Parent under the Merger Agreement. The Financing Parties are not parties to the Merger Agreement, but the Merger Agreement contains customary provisions requiring the parties to the Merger Agreement to obtain the consent of the applicable Financing Parties before entering into any amendment that would adversely affect such Financing Parties.

At any time prior to the Effective Time, the parties to the Merger Agreement may, to the extent permitted by applicable law, (1) extend the time for the performance of any of the obligations or acts of any of the other parties, (2) waive any inaccuracies in the representations and warranties of the other parties set forth in the Merger Agreement or any document delivered pursuant thereto or (3) subject to applicable law, waive compliance with any of the agreements or conditions of the other parties contained therein. Any agreement on the part of a party to any such waiver will be valid only if set forth in a written instrument executed and delivered by a duly authorized officer on behalf of such party. No failure or delay of any party in exercising any right or remedy thereunder will operate as a waiver thereof, nor will any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such right or power, or any course of conduct, preclude any other or further exercise thereof or the exercise of any other right or power.

Specific Performance

The parties to the Merger Agreement agreed that irreparable damage, for which monetary damages, even if available, would not be an adequate remedy, would occur if any of the provisions of the Merger Agreement were not performed in accordance with their specific terms or were otherwise breached. Accordingly, each of DoubleVerify (on behalf of itself and on behalf of the holders of Company Common Stock as third-party beneficiaries), Parent and Merger Sub agreed that, at any time prior to the valid termination of the Merger Agreement, the parties will be entitled to seek specific performance of the terms of the Merger Agreement, including an injunction or injunctions to prevent breaches of the Merger Agreement and to enforce specifically the terms and provisions of the Merger Agreement, in addition to any other remedy to which such party is entitled at law or in equity, and that the right of specific performance is an integral part of the Transactions and without that right, neither DoubleVerify nor Parent would have entered into the Merger Agreement. Each of the parties to the Merger Agreement further waived (1) any defense in any action for specific performance that a remedy at law would be adequate or that an award of specific performance is not an appropriate remedy for any reason at law or equity and (2) any requirement under any law to provide any bond or to post any security as a prerequisite to obtaining equitable relief.

However, DoubleVerify will only be permitted to obtain an injunction, specific performance or other equitable remedies to enforce Parent’s and Merger Sub’s obligations to effect the Closing and to cause the Equity Financing to be funded if, and only if: (i) all of the conditions to Parent’s and Merger Sub’s obligations to close have been satisfied or waived (other than conditions that by their nature are to be satisfied by actions taken at the Closing, which are capable of being satisfied at the Closing) at the time when the Closing would have been required to occur, (ii) the Debt Financing has been funded or will be funded if the Equity Financing is funded at the Closing, (iii) DoubleVerify has irrevocably confirmed in writing (x) that DoubleVerify is ready, willing and able to take the actions within DoubleVerify’s control that are required to cause the Closing to occur if specific performance is granted and the Equity Financing and the Debt Financing are funded and (y) all of the conditions to DoubleVerify’s obligations to close have been satisfied or irrevocably waived (other than conditions that by their nature are to be satisfied by actions taken at the Closing, which are capable of being satisfied at the Closing), and (iv) Parent and Merger Sub have failed to consummate the Closing on or prior to the earlier of (x) the third business day following delivery of such confirmation and (y) one (1) business day prior to the Termination Date.

Under no circumstances will DoubleVerify be permitted or entitled to receive both a grant of specific performance to effect the Closing and payment of the Parent Termination Fee.

Governing Law; Jurisdiction; Waiver of Jury Trial

The Merger Agreement and all disputes or controversies arising out of or relating to the Merger Agreement or the Transactions are governed by, and to be construed in accordance with, the internal laws of the State of Delaware, without regard to the laws of any other jurisdiction that might be applied because of the conflicts of laws principles of the State of Delaware, except that actions brought against certain debt financing sources related parties are to be governed by and construed in accordance with the laws of the State of New York.

Each party to the Merger Agreement has irrevocably submitted to the exclusive jurisdiction and venue of the Court of Chancery of the State of Delaware (or, if jurisdiction is not available in such court, any federal court located in the State of Delaware or any other Delaware state court), in the event that any dispute or controversy arises out of the Merger Agreement or the Transactions, and has agreed that all claims with respect to such proceedings will be brought and determined only in such courts.

Each party further irrevocably waived any and all right to trial by jury in any legal proceeding arising out of or related to the Merger Agreement or the Transactions.

PROPOSAL 2: THE COMPENSATION PROPOSAL

Under Section 14A of the Exchange Act and the applicable SEC rules issued thereunder, DoubleVerify is required to submit a proposal to the DoubleVerify Stockholders to approve, on a non-binding, advisory basis, the compensation that may be paid or become payable to DoubleVerify’s named executive officers that is based on or otherwise relates to the Merger Agreement and the Transactions. This compensation is summarized in the section of this proxy statement titled “The Merger — Interests of DoubleVerify’s Directors and Executive Officers in the Merger.” The Company Board encourages you to review carefully the named executive officer merger-related compensation information disclosed in this proxy statement.

Accordingly, DoubleVerify is asking you to approve, on a non-binding, advisory basis, the compensation that will or may become payable to DoubleVerify’s named executive officers that is based on or otherwise relates to the Merger as disclosed pursuant to Item 402(t) of Regulation S-K in the section titled “The Merger — Interests of DoubleVerify’s Directors and Executive Officers in the Merger.”

The vote on this Compensation Proposal is separate and apart from the vote on the Merger Agreement Proposal. Accordingly, you may vote to approve the Merger Agreement Proposal and vote not to approve this Compensation Proposal and vice versa. Because the vote on the Compensation Proposal is advisory only, it will not be binding on DoubleVerify. Accordingly, if the Merger Agreement is adopted and the Merger is completed, the compensation will be payable, subject only to the conditions applicable thereto, regardless of the outcome of the vote on this Compensation Proposal.

THE COMPANY BOARD RECOMMENDS, ON BEHALF OF DOUBLEVERIFY, THAT YOU VOTE “FOR” APPROVAL OF THIS PROPOSAL.

TABLE OF CONTENTS

PROPOSAL 3: THE ADJOURNMENT PROPOSAL

We are asking you to approve the Adjournment Proposal, a proposal to adjourn the Special Meeting to a later date or time if the Company Board determines that it is necessary or appropriate, including to solicit additional proxies if there are insufficient votes to adopt the Merger Agreement Proposal at the time of the Special Meeting. If the Company Board determines that it is necessary or appropriate, we will ask the DoubleVerify Stockholders to vote only on this Adjournment Proposal and not to vote on the Merger Agreement Proposal or to approve, on a non-binding, advisory basis, the Compensation Proposal.

If the DoubleVerify Stockholders approve the Adjournment Proposal, we could adjourn the Special Meeting and any adjourned session of the Special Meeting and use the additional time to solicit additional proxies, including soliciting proxies from DoubleVerify Stockholders that have previously returned properly executed proxies voting against adoption of the Merger Agreement. Among other things, approval of the Adjournment Proposal could mean that, even if we had received proxies representing a sufficient number of votes against adoption of the Merger Agreement such that the Merger Agreement Proposal would be defeated, we could adjourn the Special Meeting without a vote on the adoption of the Merger Agreement and seek to convince the holders of those shares of Company Common Stock to change their votes to votes in favor of adoption of the Merger Agreement. Additionally, we may seek to adjourn the Special Meeting if a quorum is not present or otherwise at the discretion of the Chairman of the Special Meeting.

Approval of the Adjournment Proposal to adjourn the Special Meeting, (a) when a quorum is present, requires the affirmative vote of the DoubleVerify Stockholders holding a majority in voting power of the shares of Company Common Stock represented at the Special Meeting (present virtually or represented by proxy) and (b) when a quorum is not present, the Chairman of the Special Meeting or DoubleVerify Stockholders holding a majority in voting power of the outstanding shares of Company Common Stock represented at the Special Meeting (present virtually or represented by proxy) may adjourn the Special Meeting to another place, if any, date and time.

THE COMPANY BOARD RECOMMENDS, ON BEHALF OF DOUBLEVERIFY, THAT YOU VOTE “FOR” APPROVAL OF THIS PROPOSAL.

MARKET PRICES AND DIVIDEND DATA

The Company Common Stock is listed on the NYSE under the symbol “DV.” As of the close of business on the Record Date, there were [•] shares of Company Common Stock outstanding held by approximately [•] DoubleVerify Stockholders of record. The actual number of DoubleVerify Stockholders is greater than this number of record holders and includes DoubleVerify Stockholders who are beneficial owners, but whose shares of Company Common Stock are held in street name by brokers and other nominees. The Company Board is responsible for determining our dividend policy. The timing and level of any dividends will necessarily depend on the Company Board’s assessments of earnings, financial condition, capital requirements and other factors, including restrictions, if any, imposed by our lenders.

On [•], 2026, the latest practicable trading day before the filing of this proxy statement, the closing price for the Company Common Stock on the NYSE was $[•] per share. You are encouraged to obtain current market quotations for the Company Common Stock.

Following the Merger, there will be no further market for Company Common Stock, and it will be delisted from the NYSE and deregistered under the Exchange Act. As a result, following the Merger we will no longer file periodic reports with the SEC. In the event that the Merger is not consummated, our payment of any future dividends would be at the discretion of the Company Board and will depend on then-existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects, and other factors the Company Board may deem relevant.

Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Percentage computations are based on 155,027,171 shares of Company Common Stock outstanding as of September 9, 2026. Except as otherwise indicated in the footnotes to the table, each of the beneficial owners listed has, to our knowledge, sole voting and investment power with respect to the indicated shares of Company Common Stock. Unless otherwise set forth in the footnotes to the table, the address for each listed stockholder is 462 Broadway, New York, NY 10013.

VOTING AGREEMENT

The summary of the material provisions of the Voting Agreement set forth below and elsewhere in this proxy statement is qualified in its entirety by reference to the Voting Agreement, a copy of which is attached as Annex D. This summary does not purport to be complete and may not contain all of the information about the Voting Agreement that is important to you. We encourage you to read the form Voting Agreement carefully in its entirety, as well as this proxy statement in its entirety, including the annexes attached to this proxy statement before making any decisions regarding the Merger.

Concurrently with the execution and delivery of the Merger Agreement on August 6, 2026, as an inducement to Parent’s willingness to enter into the Merger Agreement, the Supporting Stockholders entered into the Voting Agreement with Parent pursuant to which the Supporting Stockholders have agreed, among other things and subject to the terms and conditions of the Voting Agreement, to vote the shares of Company Common Stock owned by the Supporting Stockholders (A) in favor of (i) the Merger and the adoption of the Merger Agreement and each of the other Transactions contemplated thereby, (ii) any other actions presented at any meeting of the DoubleVerify Stockholders that are necessary to consummate the Transactions, and (iii) any proposal to adjourn or postpone such meeting to a later date if there are not sufficient votes for the adoption of the Merger Agreement on the date on which such meeting is held, and (B) against any proposal, action or agreement that would reasonably be expected to impede, interfere with, delay, postpone or adversely affect the Merger or Transactions. The Supporting Stockholders own approximately [11.8]% of the outstanding shares of Company Common Stock as of the close of business on the Record Date. In the event either Supporting Stockholder acquires record or beneficial ownership of any shares of Company Common Stock after the execution of the Voting Agreement, such additional shares will automatically become subject to the terms and conditions of the Voting Agreement. The Supporting Stockholders also agreed not to transfer their shares of Company Common Stock, subject to certain exceptions set forth in the Voting Agreement.

Under the Voting Agreement, the Supporting Stockholders irrevocably waived all appraisal rights under Section 262 of the DGCL with respect to their shares of Company Common Stock in connection with the Merger and the Transactions. The Supporting Stockholders have also agreed not to commence or participate in any action against Parent, DoubleVerify or any of their respective subsidiaries or successors (a) challenging the validity of, or seeking to enjoin or delay the operation of, the Voting Agreement or the Merger Agreement (including any claim seeking to enjoin or delay the closing) or (b) alleging a breach of any duty of the Company Board or Parent in connection with the Merger agreement, the Voting Agreement or the Transactions, subject to certain exceptions, to participate in any action brought by DoubleVerify against Parent or its affiliates, and to enforce their respective rights under the Voting Agreement or the Merger Agreement.

The Voting Agreement terminates upon the earliest of: (a) the valid termination of the Merger Agreement in accordance with its terms; (b) the Effective Time; (c) any amendment to the Merger Agreement that is effectuated without the Supporting Stockholders’ prior written consent and that reduces the Merger Consideration or is otherwise materially adverse to DoubleVerify Stockholders; (d) receipt by DoubleVerify of the Required Company Stockholder Approval; and (e) the mutual written consent of the parties.

TABLE OF CONTENTS

FUTURE STOCKHOLDER PROPOSALS

If the Merger is completed, we will have no public DoubleVerify Stockholders and there will be no public participation in any future meetings of DoubleVerify Stockholders. However, if the Merger is not completed, DoubleVerify Stockholders will continue to be entitled to attend and participate in DoubleVerify Stockholder meetings.

DoubleVerify will hold the regular annual meeting of the DoubleVerify Stockholders in 2027 (the “2027 Annual Meeting of Stockholders”) only if the Merger is not completed.

Stockholder Proposals for 2027 Annual Meeting of Stockholders

A stockholder who wishes to present a proposal for inclusion in the Company’s proxy statement for the 2027 Annual Meeting of Stockholders pursuant to Exchange Act Rule 14a-8, must submit such proposal to the Corporate Secretary at the Company’s principal executive offices. Proposals must be received no later than the close of business on December 11, 2026, or such other date that DoubleVerify announces in accordance with SEC rules and the Company’s Bylaws. Proposals must comply with all requirements of Exchange Act Rule 14a-8. Submitting a proposal does not guarantee its inclusion, which is governed by SEC rules and other applicable requirements.

Under the notice provision of DoubleVerify’s Bylaws, for director nominations or other business to be properly brought before an annual meeting by a stockholder where such nominees or business is not to be included in DoubleVerify’s proxy statement, the stockholder must deliver notice in writing to DoubleVerify’s Corporate Secretary, at DoubleVerify’s principal executive offices, not later than the close of business on February 20, 2027, nor earlier than the close of business on January 21, 2027.

OTHER MATTERS

Other Matters

The Company Board knows of no other business that will be presented for consideration at the Special Meeting. If other matters are properly brought before the Special Meeting, however, it is the intention of the persons named in the proxy to vote the shares of Company Common Stock represented thereby on such matters in accordance with their best judgment.

Householding of Special Meeting Materials

DoubleVerify delivers only one proxy statement to multiple stockholders sharing the same address unless it has received different instructions from one or more of them. This method of delivery is known as “householding”. Householding reduces the number of mailings you receive, saves on printing and postage costs and helps the environment. DoubleVerify will, upon written or oral request, promptly deliver a separate copy of the proxy statement to a DoubleVerify Stockholder at a shared address. If you would like to change your householding election, request that a single copy of this or future proxy materials be sent to your address or request a separate copy of this or future proxy materials, you should submit this request by writing Broadridge Householding Department, 51 Mercedes Way, Edgewood, NY 11717 or calling 1-866-540-7095.

Section 1.2 Closing. The closing of the Merger (the “Closing”), shall take place remotely, via electronic exchange of required Closing documentation as soon as practicable, but in any event no later than the date which is three Business Days after the date on which all conditions set forth in Article VI shall have been satisfied or, to the extent permitted by applicable Law, waived by the party entitled to grant such waiver (other than those conditions that by their terms are to be satisfied at the Closing, but subject to the satisfaction of such conditions at such time) unless another date, time or place is agreed to in writing by Parent and the Company; provided, however, that, if the Marketing Period has not ended as of such date, then the Closing shall not occur until the earlier to occur of (a) a Business Day, if any, during the Marketing Period specified by Parent on no less than three (3) Business Days’ notice to the Company and (b) three (3) Business Days following the final day of the Marketing Period, as the Marketing Period may be extended in accordance with the terms hereof (subject, in the case of each of clauses (a) and (b) above, to the satisfaction or, to the extent permitted by applicable Law, waiver (by the party entitled to grant such waiver) of the conditions set forth in Article VI on such earlier date).

Section 1.5 Certificate of Incorporation; Bylaws.

(a) At the Effective Time, the certificate of incorporation of the Company as in effect immediately prior to the Effective Time, by virtue of the Merger and without any further action on the part of any Person, shall be amended and restated so that it reads in its entirety as set forth in Exhibit B, and, as so amended, shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with its terms and as provided by the DGCL.

(b) At the Effective Time, by virtue of the Merger and without any further action on the part of any Person, the bylaws of the Company (the “Company Bylaws”) as in effect immediately prior to the Effective Time shall be amended and restated to read in their entirety as the bylaws of Merger Sub in effect immediately prior to the Effective Time (with such changes as the Company and Parent shall mutually agree in writing), except that all references therein to Merger Sub shall be automatically amended and shall become references to the Surviving Corporation, and, as so amended, shall be the bylaws of the Surviving Corporation until thereafter amended in accordance with their terms, the certificate of incorporation of the Surviving Corporation and as provided by the DGCL.

EXCHANGE OF CERTIFICATES

Section 2.1 Conversion of Capital Stock.

(a) At the Effective Time, by virtue of the Merger and without any action on the part of the Parties, the holders of any of the securities of the Parties, or any other Person, the following shall occur:

(i) Each share of common stock, par value $0.001 per share, of the Company (such shares, collectively, the “Shares”) issued and outstanding as of immediately prior to the Effective Time (other than as provided in clause (ii) of this Section 2.1(a) and in respect of any Dissenting Shares, which shall have only those rights set forth in Section 2.5) shall be converted automatically into and shall thereafter represent the right to receive $13.60 in cash, without interest, and subject to deduction for any required withholding Tax in accordance with Section 2.4 (the “Merger Consideration”). From and after the Effective Time, subject to Section 2.5, all Shares shall no longer be outstanding and shall automatically be canceled and shall cease to exist, and shall thereafter only represent the right to receive the Merger Consideration to be issued or paid in accordance with Section 2.3, without interest.

(ii) Each Share held by the Company or owned, directly or indirectly, by Parent, Merger Sub or any direct or indirect wholly owned Subsidiary of Parent, Merger Sub, or the Company as of immediately prior to the Effective Time (including those held in the Company’s treasury) (collectively, the “Cancelled Shares”) shall automatically be canceled and shall cease to exist, and no consideration shall be delivered in exchange therefor.

(iii) Each share of common stock of Merger Sub, par value $0.0001 per share, issued and outstanding immediately prior to the Effective Time shall automatically be converted into and become one validly issued, fully paid and non-assessable share of common stock, par value $0.0001 per share, of the Surviving Corporation.

(b) If at any time during the period between the date of this Agreement and the Effective Time, any change in the outstanding Shares, or securities convertible into or exchangeable into or exercisable for Shares, shall occur as a result of any reclassification, recapitalization, stock split (including a reverse stock split), division or subdivision or consolidation, combination, exchange or readjustment of shares, or any stock dividend, stock distribution or similar transaction with a record date during such period, or any merger or other similar transaction, the Merger Consideration shall be equitably adjusted, without duplication, to provide the holders of Shares the same economic effect as contemplated by this Agreement prior to such event. Nothing in this Section 2.1(b) shall be construed to permit any action that is otherwise prohibited or restricted by any other provision of this Agreement.

Section 2.2 Treatment of Options and Other Equity-Based Awards.

(a) At the Effective Time, each option (each, a “Company Stock Option”) to purchase Shares granted pursuant to the Pixel Group Holdings Inc. 2017 Omnibus Equity Incentive Plan or the DoubleVerify Holdings, Inc. 2021 Omnibus Equity Incentive Plan (the “Company Stock Plans”), that is outstanding immediately prior to the Effective Time will be canceled, and in exchange therefor:

(i) to the extent such Company Stock Option (x) is vested as of immediately prior to the Effective Time or (y) vests in accordance with its terms at the Effective Time as a result of the consummation of the Merger, the Surviving Corporation will pay to the former holder thereof as soon as practicable following the Effective Time an amount in cash (without interest, and subject to deduction for any required Tax withholding in accordance with Section 2.4) equal to the product of (x) the excess of the Merger Consideration over the exercise price per Share under such Company Stock Option and (y) the number of Shares subject to the vested portion of such Company Stock Option; and

A-3

TABLE OF CONTENTS

(ii) to the extent such Company Stock Option (x) is unvested as of immediately prior to the Effective Time and (y) does not vest in accordance with its terms at the Effective Time as a result of the consummation of the Merger, the former holder thereof will instead be entitled to receive a cash award (a “Cash Replacement Award”) in an amount equal to the product of (x) the excess of the Merger Consideration over the exercise price per Share under such Company Stock Option and (y) the number of Shares subject to the unvested portion of such Company Stock Option, which Cash Replacement Award will, except as otherwise provided in Section 2.2(f), remain subject to the same time-based vesting schedule and other related terms and conditions, including with respect to vesting and forfeiture on termination of employment, as applied to the corresponding Company Stock Option immediately prior to the Effective Time, and will be paid, less applicable Tax withholding in accordance with Section 2.4 and without interest, within 30 days following the applicable vesting date;

provided, that if the exercise price per Share of any such Company Stock Option is equal to or greater than the Merger Consideration, such Company Stock Option will be canceled without any cash payment or Cash Replacement Award being made or granted in respect thereof.

(b) At the Effective Time, each restricted stock unit granted pursuant to a Company Stock Plan that vests based solely on continued service (each, a “Company RSU”), and each performance share unit granted pursuant to a Company Stock Plan (each, a “Company PSU”) as to which the applicable performance-based vesting conditions have been satisfied and that remain subject solely to service-based vesting conditions (each, an “Earned Company PSU”), in each case, that is outstanding immediately prior to the Effective Time will be canceled, and in exchange therefor, (i) to the extent such Company RSU or Earned Company PSU (x) is vested as of immediately prior to the Effective Time (and is not subject to a deferral election pursuant to Section 409A of the Code) or (y) vests in accordance with its terms at the Effective Time as a result of the consummation of the Merger (and is not subject to a deferral election pursuant to Section 409A of the Code), Parent will cause the Surviving Corporation or its applicable Subsidiary to pay to the former holder thereof as soon as practicable following the Effective Time an amount in cash (without interest, and subject to deduction for any required Tax withholding in accordance with Section 2.4) equal to the product of (x) the Merger Consideration and (y) the number of Shares subject to such Company RSU or Earned Company PSU (with the performance conditions applicable to such Company PSU deemed achieved based on actual performance of the performance conditions applicable to such Company PSU as of immediately before the Effective Time), as applicable, and (ii) to the extent such Company RSU or Earned Company PSU (x) is unvested as of immediately prior to the Effective Time (or is vested but is subject to a deferral election pursuant to Section 409A of the Code) and (y) does not vest in accordance with its terms at the Effective Time as a result of the consummation of the Merger (or does vest but is subject to a deferral election pursuant to Section 409A of the Code), the former holder thereof will instead be entitled to receive a Cash Replacement Award in an amount equal to the product of (x) the Merger Consideration and (y) the number of Shares subject to such unvested Company RSU or unvested Earned Company PSU, as applicable, which Cash Replacement Award will, except as otherwise provided in Section 2.2(f), remain subject to the same time-based vesting schedule and other terms and conditions, including with respect to vesting and forfeiture on termination of employment, as applied to the corresponding Company RSU or Earned Company PSU immediately prior to the Effective Time, and will be paid, less applicable Tax withholding in accordance with Section 2.4 and without interest, within 30 days following the applicable original vesting date.

(c) At the Effective Time, each Company PSU (other than any Earned Company PSU) that is outstanding immediately prior to the Effective Time will automatically be converted into and substituted with a restricted stock unit award (each, a “Converted PSU”) with respect to a number of Shares as determined by the Compensation Committee of the Company Board in accordance with the terms of the applicable award agreement governing such Company PSU (with such determination subject to Parent’s review and reasonable comment). Each Converted PSU will be canceled and converted into the right to receive a Cash Replacement Award equal to the product of (x) the Merger Consideration and (y) the number of Shares subject to such Converted PSU, which Cash Replacement Award will, except as otherwise provided in Section 2.2(f), remain subject to the same time-based vesting schedule and other terms and conditions, including with respect to vesting and forfeiture on termination of employment, as applied to the corresponding Converted PSU immediately prior to the Effective Time, and will be paid,

less applicable Tax withholdings in accordance with Section 2.4 and without interest, within 30 days following the applicable original vesting date.

(d) As promptly as practicable following the date hereof, the Company Board or an appropriate Company Committee will take all actions necessary to provide that (i) no new offering period will commence under the DoubleVerify Holdings, Inc. Employee Stock Purchase Plan (the “Company ESPP”) on or after the date hereof, (ii) no individual who is not participating in the Company ESPP as of the date hereof may commence participation therein, (iii) no participant may increase such participant’s rate of payroll contributions under the Company ESPP from the rate in effect as of the date of this Agreement, (iv) the Company ESPP will terminate no later than immediately prior to the Effective Time, and (v) any outstanding offering period under the Company ESPP will be shortened so that a purchase date will occur under the Company ESPP on or prior to the date that is five Business Days prior to the anticipated Closing Date (or such other date as may be mutually agreed by the Company and Parent), and each participant’s accumulated payroll contributions under the Company ESPP will be used to purchase Shares in accordance with the terms of the Company ESPP on such purchase date, with any remaining amounts refunded to participants as soon as practicable. Any Shares purchased under the Company ESPP in accordance with this Section 2.2(d) will be treated as outstanding for the purpose of Section 2.1.

(e) Prior to the Effective Time, the Company, through the Company Board or an appropriate Company Committee, will adopt such resolutions and cause such other actions to be taken as it may deem necessary in its reasonable discretion to (i) effectuate the actions contemplated by this Section 2.2, (ii) ensure that after the Effective Time no holder of any Company Stock Option, Company RSU, Company PSU, Converted PSU, or any Cash Replacement Award and no participant in the Company ESPP, will have any right thereunder to acquire any securities of the Company, the Surviving Corporation or Parent, or to receive any payment or benefit with respect thereto, except as provided in this Section 2.2, and (iii) ensure that, on and after the Effective Time, no new Company Stock Option, Company RSU, or Company PSU or other rights with respect to Shares may be granted or outstanding under any Company Stock Plan or otherwise, other than the Cash Replacement Awards contemplated by this Section 2.2.

(f) Notwithstanding anything to the contrary in this Section 2.2, each Cash Replacement Award will be payable solely in cash and will not, by virtue of the award, entitle the holder thereof to acquire any Shares or other securities of, or any equity interest in, the Company, the Surviving Corporation, Parent or any of their respective Affiliates, or to any dividends or dividend equivalents. Parent will, or will cause the Surviving Corporation or its applicable Subsidiary to assume and honor each Cash Replacement Award in accordance with the terms and this Section 2.2. Notwithstanding the payment timing set forth in this Section 2.2, to the extent that any Company Stock Option, Company RSU, Company PSU, Earned Company PSU or Converted PSU (or the Cash Replacement Award issued in respect thereof) constitutes “nonqualified deferred compensation” within the meaning of Section 409A of the Code, the corresponding Cash Replacement Award will instead be paid on the settlement or payment date(s), and in the form, that applied to such award immediately prior to the Effective Time, in each case to the extent necessary to avoid the imposition of any Tax or penalty under Section 409A of the Code. The Cash Replacement Awards and the other actions contemplated by this Section 2.2 are intended to be exempt from, or to comply with Section 409A of the Code, and this Section 2.2 will be construed and administered accordingly. Further, each Cash Replacement Award will provide that, upon (i) an involuntary termination of the holder thereof without “Cause” (as such term is defined in the award agreement governing the applicable Company Stock Option, Company RSU, or Company PSU) within the 12-month period immediately following the Closing, (ii) if the award agreement governing the applicable Company Stock Option, Company RSU, or Company PSU or any other employment-related agreement by and between the holder and the Company made available to Parent prior to the date hereof provides for a “Good Reason” definition, a voluntary resignation of the holder thereof with “Good Reason” (as such term is defined in the award agreement governing the applicable Company Stock Option, Company RSU, or Company PSU or any other employment-related agreement by and between the holder and the Company made available to Parent prior to the date hereof) within the 12-month period immediately following the Closing, or (iii) the death of the holder thereof, in each case prior to the final vesting date of such Cash Replacement Award, the then-unvested portion of such Cash Replacement Award will immediately vest and be paid in full.

Section 2.3 Exchange and Payment.

(a) Prior to the Effective Time, Parent shall enter into an agreement (in form and substance reasonably acceptable to the Company) (the “Paying Agent Agreement”) with the Company’s transfer agent, or any other reputable bank or trust company reasonably acceptable to the Company and Parent, to act as agent for the holders of Shares, other than the Cancelled Shares and any Dissenting Shares, to receive the Merger Consideration to which such holders shall become entitled pursuant to this Article II, and to act as agent for the stockholders of the Company in connection with the Merger (the “Paying Agent”). At or prior to or substantially concurrently with the Effective Time, Parent shall deposit (or cause to be deposited): (i) with the Paying Agent an aggregate amount of cash that, when taken together with cash available on the Company’s balance sheet that is deposited with the Paying Agent at the Effective Time, is sufficient to pay the aggregate Merger Consideration in accordance with Section 2.1(a) (such cash being hereinafter referred to as the “Payment Fund”), and (ii) with the Company, cash in an amount that, when taken together with cash available on the Company’s balance sheet, is sufficient for the Company to pay the aggregate amount payable at the Closing pursuant to Section 2.2 (solely with respect to Company Stock Options, Company RSUs and Company PSUs that are vested as of immediately prior to the Effective Time) in accordance with this Agreement (such cash being hereinafter referred to as the “Compensatory Award Fund”). The Payment Fund and the Compensatory Award Fund shall not be used for any purpose other than to fund payments due pursuant to Section 2.1(a) and Section 2.2, respectively. In accordance with the terms and conditions of the Paying Agent Agreement, Parent shall cause the Paying Agent to, pursuant to irrevocable instructions delivered by Parent to the Paying Agent, deliver the Merger Consideration contemplated to be issued pursuant to Section 2.1(a) out of the Payment Fund. The Surviving Corporation shall, and Parent shall cause the Surviving Corporation or the applicable Subsidiary of the Surviving Corporation to, pay the amounts due at the Closing pursuant to Section 2.2 (solely with respect to Company Stock Options, Company RSUs and Company PSUs that are vested as of immediately prior to the Effective Time) contemplated to be paid out of the Compensatory Award Fund. The Surviving Corporation shall, and Parent shall cause the Surviving Corporation to, pay all charges and expenses, including those of the Paying Agent, incurred by it in connection with the exchange of Shares for the Merger Consideration and other amounts contemplated by this Article II.

(b) As promptly as reasonably practicable following the Effective Time (and in any event not later than the third Business Day following the Effective Time), Parent shall cause the Paying Agent to mail to each holder of record of an outstanding certificate or outstanding certificates (“Certificates”) that immediately prior to the Effective Time represented outstanding Shares that were converted into the right to receive the Merger Consideration with respect thereto pursuant to Section 2.1(a), (i) a form of letter of transmittal, which shall specify that delivery shall be effected, and risk of loss and title to the Certificates held by such Person shall pass, only upon proper delivery of the Certificates (or upon compliance with the replacement requirements established by the Paying Agent in lieu thereof in accordance with Section 2.3(i)), and shall otherwise be in customary form and have such other provisions as Parent, the Company, and the Paying Agent may reasonably agree, and (ii) instructions for use in effecting the surrender of such Certificates (or complying with the replacement requirements established by the Paying Agent in lieu thereof in accordance with Section 2.3(i)) in exchange for the Merger Consideration payable with respect thereto pursuant to Section 2.1(a). Upon surrender of a Certificate to the Paying Agent (or upon compliance with the replacement requirements established by the Paying Agent in lieu thereof in accordance with Section 2.3(j) and the Paying Agent Agreement), together with such letter of transmittal, duly completed and validly executed in accordance with the instructions thereto, and such other documents as may be required pursuant to such instructions and the Paying Agent Agreement, the holder of such Certificate shall be entitled to receive, and Parent shall cause the Paying Agent to pay and deliver to such holder, in accordance with the terms of this Agreement and the letter of transmittal, in exchange therefor the Merger Consideration for each Share formerly represented by such Certificate, and the Certificate so surrendered shall forthwith be canceled.

(c) As promptly as reasonably practicable following the Effective Time (and in any event not later than the third Business Day following the Effective Time), Parent shall cause the Paying Agent to issue and deliver to each holder of uncertificated Shares represented by book entry (“Book-Entry Shares”) a check or wire transfer for the amount of cash that such holder is entitled to receive pursuant to Section 2.1(a) in respect of such Book-Entry Shares, without such holder being required to deliver a

A-6

TABLE OF CONTENTS

Certificate or an executed letter of transmittal to the Paying Agent, and such Book-Entry Shares shall then be canceled. No interest will be paid or accrued for the benefit of holders of Certificates or Book-Entry Shares on the Merger Consideration payable in respect of Certificates or Book-Entry Shares.

(d) If payment of the Merger Consideration is to be made to a Person other than the Person in whose name the surrendered Certificate or Book-Entry Share is registered, it shall be a condition of payment that (i) (A) such Certificate so surrendered shall be properly endorsed or shall be otherwise in proper form for transfer or (B) such Book-Entry Share shall be properly transferred (and accompanied by all documents reasonably required by the Paying Agent in accordance with the Paying Agent Agreement), as applicable, and (ii) the Person requesting such payment shall have (A) paid any transfer and other Taxes required by reason of the payment of the Merger Consideration to a Person other than the registered holder of the Certificate or Book-Entry Share surrendered or (B) established to the satisfaction of Parent that such Tax either has been paid or is not applicable.

(e) Until surrendered or canceled as contemplated by this Section 2.3, each Certificate or Book-Entry Share shall be deemed at any time after the Effective Time to represent only the right to receive the Merger Consideration payable in respect of Shares theretofore represented by such Certificate or Book-Entry Shares, as applicable, pursuant to Section 2.1(a), without any interest thereon. No interest shall be paid or accrue on any cash payable upon surrender of any Certificate or Book-Entry Share.

(f) With respect to Shares held, directly or indirectly, through the Depository Trust Company (“DTC”), prior to the Effective Time, Parent and the Company shall use commercially reasonable efforts to cooperate to establish procedures with the Paying Agent, DTC, DTC’s nominees and such other necessary third-party intermediaries to ensure that (i) if the Closing occurs at or prior to 11:30 a.m. (New York time) on the Closing Date, the Paying Agent shall transmit to DTC or its nominees as promptly as practicable after the Effective Time (and in any event on the Closing Date), an amount in cash in immediately available funds sufficient to pay the Merger Consideration with respect to all Shares held of record by DTC or such nominee as of immediately prior to the Effective Time (such amount, the “DTC Payment”), and (ii) if the Closing occurs after 11:30 a.m. (New York time) on the Closing Date, the Paying Agent shall transmit to DTC or its nominee as promptly as practicable after the Effective Time (and in any event on the first Business Day after the Closing Date) an amount in cash in immediately available funds equal to the DTC Payment.

(g) All cash paid upon the surrender for exchange or cancellation of Certificates or Book-Entry Shares in accordance with the terms of this Article II shall be deemed to have been paid in full satisfaction of all rights pertaining to the Shares formerly represented by such Certificates or Book-Entry Shares. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the Shares that were outstanding immediately prior to the Effective Time. If, after the Effective Time, Certificates are presented to the Surviving Corporation or the Paying Agent for transfer or transfer is sought for Book-Entry Shares, such Certificates or Book-Entry Shares shall be canceled and exchanged as provided in this Article II, subject to applicable Law in the case of Dissenting Shares.

(h) The Surviving Corporation may cause the Paying Agent to invest any cash included in the Payment Fund as directed by Parent; provided, that (i) any investment of such cash shall in all events be in short-term obligations of the United States of America with maturities of no more than 30 days or guaranteed by the United States of America and backed by the full faith and credit of the United States of America, and (ii) such investments shall only be invested in the manner provided in, or otherwise in accordance with, the Paying Agent Agreement. If for any reason (including investment losses or Shares ceasing to qualify as Dissenting Shares) the cash in the Payment Fund is insufficient to fully satisfy all of the payment obligations to be made in cash by the Paying Agent hereunder, Parent shall promptly deposit cash into the Payment Fund in an amount which is equal to the deficiency in the amount of cash required to fully satisfy such cash payment obligations. Any interest and other income resulting from such investments shall be payable to Parent or its designee (as directed by Parent).

(i) At any time following the date that is 12 months after the Effective Time, Parent shall be entitled to require the Paying Agent to deliver to it any funds (including any interest received with respect thereto) which have been made available to the Paying Agent and which have not been disbursed to holders of

A-7

TABLE OF CONTENTS

Certificates or Book-Entry Shares, and thereafter such holders (except to the extent representing Cancelled Shares or Dissenting Shares) shall be entitled to look to the Surviving Corporation (subject to abandoned property, escheat or other similar Laws) only as general creditors thereof with respect to the Merger Consideration payable upon due surrender of their Certificate or Book-Entry Shares. The Surviving Corporation shall pay all fees, costs, charges and expenses of the Paying Agent in connection with the exchange of Shares for the Merger Consideration. Notwithstanding the foregoing, none of Parent, the Company or the Surviving Corporation shall be liable to any Person, including any holder of Shares or Company Stock Options, Company PSUs or Company RSUs, in respect of any Merger Consideration that is delivered to a public official pursuant to applicable abandoned property, escheat or similar Laws. Any amounts remaining unclaimed by holders of any Shares as of a date which is immediately prior to the time at which such amounts would otherwise be escheat to, or become property of, any Governmental Entity, will, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of any claims or interest of any such holders of Shares (and their successors, assigns or personal representatives) previously entitled thereto.

(j) If any Certificate shall have been lost, stolen or destroyed, then upon (i) the making of a customary affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and (ii) if required by the Paying Agent in accordance with the Paying Agent’s customary replacement requirements and the Paying Agent Agreement, the posting by such Person of a bond in customary amount as indemnity against any claim that may be made against it or the Surviving Corporation with respect to such Certificate, the Surviving Corporation shall cause the Paying Agent to deliver, in exchange for such lost, stolen or destroyed Certificate, the Merger Consideration payable in respect thereof pursuant to this Agreement.

(k) All Merger Consideration and Cash Replacement Awards issued or paid upon conversion of the Shares, the Company Stock Options, the Company PSUs or the Company RSUs, as applicable, in accordance with the terms of this Agreement, shall be deemed to have been issued and paid in full satisfaction of all rights pertaining to such Shares, Company Stock Options, Company PSUs, or Company RSUs, as the case may be.

Section 2.4 Withholding Rights. Each of Parent, the Company, the Surviving Corporation, the Paying Agent, and any other applicable withholding agent (each, a “Withholding Agent”) shall be entitled to deduct and withhold from the consideration otherwise payable to any holder of Shares or otherwise pursuant to this Agreement such amounts as the applicable Withholding Agent is required to deduct and withhold with respect to the making of such payment under the United States Internal Revenue Code of 1986, as amended (the “Code”) or any provision of state, local or foreign Tax Law. Except with respect to (a) any payments made in the nature of compensation to employees or former employees pursuant to the following sentence (b) withholding in the nature of backup withholding, or (c) withholding attributable to a failure by the Company to deliver the certificate or notice required by Section 5.19(b), prior to an applicable Withholding Agent making any deduction or withholding determined to be required under applicable Tax Law, Parent or an applicable Withholding Agent will provide prompt notice of such withholding to the applicable holder, and the parties hereto shall reasonably cooperate in good faith to eliminate or reduce any such deduction or withholding (including through the request and provision of any statements, forms or other documents to reduce or eliminate any such deduction or withholding). Any payments made to holders in respect of Company Stock Options, Company RSUs, or Company PSUs will be made through the payroll system of the Company, its applicable Subsidiary, or the Surviving Corporation. To the extent that any such amounts withheld pursuant to this Section 2.4 are timely and properly paid over to the appropriate Governmental Entity by the applicable Withholding Agent, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such withholding was made.

Section 2.5 Dissenting Shares. Notwithstanding anything to the contrary in this Agreement, Shares issued and outstanding immediately prior to the Effective Time that are held by any holder or beneficially owned by a “beneficial owner” (as defined in Section 262(a) of the DGCL) who has not voted in favor of the adoption of this Agreement or consented thereto in writing, who properly demands appraisal of such Shares pursuant to, and who otherwise complies in all respects with, Section 262 of the DGCL (each such Share, a “Dissenting Share”) shall not be converted into the right to receive the Merger Consideration, but instead shall be entitled to only such rights as are granted by Section 262 of the DGCL. Such holders or beneficial owners

of Dissenting Shares will be entitled to receive payment of the appraised value of such Dissenting Shares in accordance with the provisions of Section 262 of the DGCL unless and until (i) such Person fails to perfect or otherwise fails to comply with the provisions of Section 262 of the DGCL, (ii) such Person effectively withdraws, waives or loses such Person’s right to appraisal under the DGCL with respect to such Dissenting Shares, or (iii) a court of competent jurisdiction determines that such holder is not entitled to the relief provided by Section 262 of the DGCL. Upon the occurrence of an event set forth in clause (i), (ii) or (iii) above with respect to a Person, each such Dissenting Share of such Person shall be deemed, to the fullest extent permitted by applicable Law, to have been converted into, and have become exchangeable for, as of the Effective Time, and shall thereafter represent only the right to receive, the Merger Consideration in accordance with Section 2.1(a), without interest, and shall not thereafter be deemed to be Dissenting Shares. Prior to the Effective Time, (A) the Company shall give prompt written notice to Parent of any demands received by the Company for appraisal of any Dissenting Shares, and (B) give Parent the opportunity to direct and control (provided that (1) the Company shall have the right to participate in, and (2) prior to the Effective Time, Parent shall reasonably consult in good faith with the Company with respect to) all negotiations and proceedings with respect to such demands.

Section 4.7 Financing. Parent has delivered to the Company a true, correct and complete copy of the executed (x) equity commitment letter, dated as of the date of this Agreement, by and among Elliott Associates, L.P. and Elliott International, L.P. (each, an “Equity Investor” and collectively, the “Equity Investors”) and Parent (the “Equity Commitment Letter” and, together with the Debt Commitment Letter, the “Commitment Letters”) pursuant to which, upon the terms and subject to the conditions set forth therein, the Equity Investors have agreed to invest in Parent their respective amounts set forth in the Equity Commitment Letter (the “Equity Financing” and together with the Debt Financing, collectively, the “Financing”) and (y) the Debt Commitment Letter and the Debt Fee Letter, provided that the Debt Fee Letter may be redacted for fee amounts, economic terms of any “securities demand” provisions and the economic terms of any “market flex” provisions, none of which redacted terms or provisions would reasonably be expected to reduce the aggregate principal amount of the Debt Financing to be funded on the Closing Date, delay or otherwise impede the occurrence of the Closing Date or impose additional or more onerous conditions precedent to the funding of the Debt Financing on the Closing Date. As of the date of this Agreement, (i) each Commitment Letter is in full force and effect and represents the valid, binding and enforceable obligation (subject to the Enforceability Exceptions) of Parent and, to the knowledge of Parent, each other party thereto to provide the financing contemplated thereby subject only, in the case of the Debt Financing, to the satisfaction or waiver of the Financing Conditions, (ii) the commitments under the Commitment Letters have not been withdrawn or rescinded in any respect, and the Commitment Letters and the other Debt Commitment Papers have not been amended, waived or otherwise modified in any manner and no such withdrawal, rescission, amendment, waiver or other modification is contemplated (other than any amendment or modification of the Debt Commitment Papers to appoint additional joint lead arrangers, joint bookrunners, managers, co-managers, agents or co-agents, to award titles or allocations to any such Person, to provide for the execution of customary joinder documentation or to provide for the assignment and reallocation of a portion of the commitments thereunder, in each case as contemplated by Section 2 of the Debt Commitment Letter), (iii) Parent has fully paid (or caused to be paid) any and all commitment fees and other amounts that are due and payable on or prior to the date of this Agreement in connection with the Debt Financing, (iv) neither Parent nor any of its Affiliates has entered into any agreement, side letter or other commitment or arrangement relating to the financing of the Transactions that imposes or permits the imposition of conditions precedent to the funding of the Debt Financing on the Closing Date or would otherwise affect the availability of the Debt Financing on the Closing Date or, delay or otherwise impede the occurrence of the Closing Date, other than, in the case of agreements, side letters and other commitments or arrangements relating to the financing of the Transactions, the Debt Commitment Letter and the Debt Fee Letter, (v) no breach or default has occurred, and no event has occurred which, with or without notice, lapse of time or both, would constitute a breach or default, or result in a failure to satisfy the conditions precedent, on the part of Parent or Merger Sub or, to the knowledge of Parent, any other party thereto under any term of any Commitment Letter and (vi) assuming the satisfaction of the conditions set forth in Article VI and the completion of the Marketing Period, Parent has no reason to believe that (A) any of the Financing Conditions will not be satisfied on a timely basis, or (B) the Financing will not be made available to Parent at the Closing in accordance with the terms and conditions of the Commitment Letters. There are no conditions precedent or other contingencies directly or indirectly related to the funding of the full amount of the Financing other than, in the case of the Debt Financing, the Financing Conditions. Assuming the satisfaction of the conditions set forth in Article VI and that the Financing is funded on the Closing Date in accordance with the applicable Commitment Letters, the net proceeds of the Debt Financing (after giving effect to any “market flex” provisions), together with cash on hand, cash and cash equivalents of the Company and its Subsidiaries and other sources of immediately available funds of Parent, will be sufficient to enable Parent and Merger Sub to pay (w) the aggregate Merger Consideration and all amounts payable pursuant to Article II and to consummate the Closing, (x) all amounts of Indebtedness of the Company and its Subsidiaries required to be repaid, redeemed, prepaid, discharged or terminated at the Closing in connection with the Transactions (including under the Company Credit Agreement), (y) all fees, costs and expenses required to be paid by Parent and Merger Sub at the Closing in connection with the Transactions and the Debt Financing, including the fees, costs and expenses of Parent, Merger Sub and their respective Affiliates and their respective Representatives, and (z) all other amounts required to be paid by Parent or Merger Sub in connection with the consummation of the Transactions on the Closing Date (the minimum amount sufficient to finance such payments, the “Required Amount”). Each of Parent and Merger Sub acknowledges and agrees that, notwithstanding anything to the contrary in this Agreement, neither Parent, Merger Sub, their respective Affiliates’ nor any other Person’s ability to obtain any financing for the

A-28

TABLE OF CONTENTS

Transactions shall be a condition to any obligations of Parent or Merger Sub hereunder, including the obligation to consummate the Transactions or to pay any portion of the Merger Consideration.

Section 4.8 Limited Guarantee. Parent has delivered to the Company a true, complete and correct copy of the executed Limited Guarantee. The Limited Guarantee is in full force and effect and constitutes the valid, binding and enforceable obligation of the Guarantors in favor of the Company, enforceable by the Company in accordance with its terms (subject to the Enforceability Exceptions). Each Guarantor is not in default or breach under any of the terms or conditions of the Limited Guarantee and no event has occurred that, with or without notice, lapse of time or both, would or would reasonably be expected to constitute a default or breach or a failure to satisfy a condition under the terms and conditions of the Limited Guarantee. Each Guarantor has access to sufficient capital to satisfy the full amount of its guaranteed obligations under the Limited Guarantee in full.

Section 4.9 Solvency. Neither Parent nor Merger Sub is entering into the Transactions with the actual intent to hinder, delay or defraud either present or future creditors of Parent, Merger Sub or their Affiliates or of the Company Group. Assuming (i) the satisfaction of the conditions set forth in Section 6.1 and Section 6.2 and (ii) the accuracy of the representations and warranties set forth in Article III, at and immediately after the Closing, and after giving effect to the Transactions, Parent, Merger Sub and their respective Affiliates (including the Surviving Corporation and the other members of the Company Group) will be Solvent. For purposes of this Agreement, the term “Solvent”, when used with respect to any Person, shall mean that, as of any date of determination, such Person shall (i) have property with fair value greater than the total amount of its debts and liabilities, subordinated, contingent or otherwise (it being understood that the amount of contingent liabilities at any time shall be computed as the amount that, in light of all the facts and circumstances existing at such time, can reasonably be expected to become an actual or matured liability), (ii) have assets with present fair salable value not less than the amount that will be required to pay its liability on its debts as they become absolute and matured, (iii) be able to pay its debts and liabilities, subordinated, contingent or otherwise, as they become absolute and matured and (iv) not be engaged in business or a transaction, and not be about to engage in a business or transaction, for which it has unreasonably small capital.

Section 4.11 Ownership of Shares. None of Parent, Merger Sub nor any of their respective controlled Affiliates owns, directly or indirectly, beneficially or of record, any Shares or any securities, Contracts or rights convertible into or exercisable or exchangeable for Shares or the right to acquire or vote any Shares, except pursuant to this Agreement. None of Parent, Merger Sub nor any of their respective “Affiliates” or “Associates” (each as defined in Section 203 of the DGCL) is or has been an “interested stockholder” (as defined in Section 203 of the DGCL) of the Company, in each case at any time during the three-year period prior to the entry into this Agreement.

Section 4.13 Investment Intention. Parent is acquiring the Shares for its own account, for investment purposes only and not with a view to the distribution (as such term is used in Section 2(11) of the Securities Act) thereof. Parent understands that, following the Closing, the Shares will not be registered under the Securities Act or any “blue sky” Laws and cannot be sold unless subsequently registered under the Securities Act, any applicable “blue sky” Laws or pursuant to an exemption from any such registration.

Section 4.14 Access to Information. Each of Parent and Merger Sub acknowledges and agrees that it and its respective Representatives have (a) had a reasonable opportunity to discuss and ask questions regarding the business of the Company Group with the management of the Company, (b) had access to the books and

that was previously furnished or made available to such Person or any of its Representatives by or on behalf of the Company in accordance with the terms of such confidentiality agreement. The Company agrees not to release or permit the release of any Person from, or to waive or permit the waiver or termination of any provision of, any standstill or similar provision of any agreement to which any of the Company or any Subsidiary of the Company is a party, other than to the extent that the Company Board or any committee thereof determines in good faith, after consultation with outside legal counsel, that the failure to provide such waiver, release or termination would reasonably be expected to be inconsistent with its fiduciary duties under applicable Law.

(b) Notwithstanding anything to the contrary in Section 5.3(a) at any time on or after the date hereof, but prior to obtaining the Required Company Stockholder Approval, the Company and its Representatives may, in response to an unsolicited bona fide written Acquisition Proposal that did not result from a breach of Section 5.3(a) (other than any such breach that is immaterial) and that the Company Board or any Company Committee determines in good faith, after consultation with the Company’s outside legal counsel and financial advisors, (x) constitutes or would reasonably be expected to lead to a Superior Proposal and (y) that the failure to take such action would be inconsistent with the Company Board’s fiduciary duties under applicable Law, (i) furnish information (including non-public information with respect to the Company Group), and afford access to the books or records or officers of the Company Group, to the Person making such Acquisition Proposal, pursuant to an Acceptable Confidentiality Agreement, (ii) engage or participate in discussions or negotiations with such Person and its Representatives regarding such Acquisition Proposal, and (iii) otherwise facilitate and encourage such Acquisition Proposal; provided, that, prior to, or substantially concurrently with, the time such information is provided or made available to such Person or its Representatives, the Company shall, subject to applicable Law and any applicable “clean team” or similar arrangement, provide or make available to Parent any non-public information concerning the Company or any of its Subsidiaries that is provided to the Person making such Acquisition Proposal or its Representatives which was not previously made available to Parent.

(c) Subject to the permitted actions contemplated by clauses (d) and (e) below, and Section 7.1(c)(ii), during the Applicable Period, neither the Company Board nor any Company Committee shall (i) withdraw, qualify, amend or modify in a manner adverse to Parent or Merger Sub, or publicly propose to withdraw, qualify, amend or modify in a manner adverse to Parent or Merger Sub, the Company Board Recommendation or approve or recommend, or publicly propose to approve or recommend, any Acquisition Proposal, (ii) fail to include the Company Board Recommendation in the Proxy Statement, (iii) adopt, authorize, approve, endorse, declare advisable or recommend, or publicly propose to adopt, authorize, approve, endorse, declare advisable or recommend, any Acquisition Proposal made or received after the date hereof, (iv) fail to reaffirm publicly the Company Board Recommendation within five Business Days of a request therefor in writing from Parent following the public disclosure of an Acquisition Proposal (other than the type referred to in the following clause (v)) (it being understood that the Company will have no obligation to make such reaffirmation on more than three separate occasions as to any one Acquisition Proposal), (v) fail to recommend against any Acquisition Proposal that is a tender or exchange offer by a third party pursuant to Rule 14d-9 or Rule 14e-2 promulgated under the Exchange Act within ten Business Days after the commencement of such tender or exchange offer (any of such actions described in clauses (i) through (v), an “Adverse Recommendation Change”), or (vi) cause or permit the Company or any of its Subsidiaries to enter into any letter of intent, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement, or other similar agreement (other than an Acceptable Confidentiality Agreement) relating to any Acquisition Proposal (an “Alternative Acquisition Agreement”).

A-34

TABLE OF CONTENTS

(d) Notwithstanding anything to the contrary set forth in this Section 5.3 or any other provision in this Agreement to the contrary, if, prior to obtaining the Required Company Stockholder Approval, (A) the Company receives a bona fide written Acquisition Proposal that did not result from a breach of this Section 5.3 (other than any such breach that is immaterial), and (B) the Company Board or any Company Committee determines in good faith, after consultation with the Company’s outside legal counsel and financial advisors, that such Acquisition Proposal constitutes a Superior Proposal and the failure to effect an Adverse Recommendation Change or terminate this Agreement pursuant to Section 7.1(c)(ii) would be inconsistent with its fiduciary duties pursuant to applicable Law, the Company Board or any Company Committee may, prior to obtaining the Required Company Stockholder Approval, (i) make an Adverse Recommendation Change, or (ii) terminate this Agreement to enter into an Alternative Acquisition Agreement with respect to such Superior Proposal in accordance with Section 7.1(c)(ii) or authorize, resolve, agree or propose publicly to take any such action, if, in each case, all of the following conditions are met:

(i) (A) the Company shall have provided to Parent four Business Days’ prior written notice, that shall (1) state expressly that the Company has received a written Acquisition Proposal that constitutes a Superior Proposal, (2) include as exhibits thereto an unredacted copy of the Alternative Acquisition Agreement and any other Contracts available to the Company to be entered into in connection with such Acquisition Proposal that the Company received, and (3) state expressly that, subject to any revisions to the terms and conditions of this Agreement, the Company Board or any Company Committee has determined to make an Adverse Recommendation Change or to terminate this Agreement in accordance with Section 7.1(c)(ii) in order to enter into the Alternative Acquisition Agreement, as applicable (provided, that in the case of this clause (A), the Company shall be required to provide Parent with a new notice, and an additional three Business Day period hereunder from the time of Parent’s receipt of such new notice, if the applicable alternative acquiror amends any of the financial terms or amends any other material term or condition of the applicable Superior Proposal before the Company Board or any Company Committee makes such Adverse Recommendation Change or terminates this Agreement), and (B) prior to making such Adverse Recommendation Change or terminating this Agreement in accordance with Section 7.1(c)(ii), as applicable, the Company shall have, and shall have caused its directors, officers and employees to have, and shall have instructed and used commercially reasonable efforts to cause its other Representatives to have, negotiated and engaged in good faith with Parent (to the extent Parent has made a request in writing to the Company to engage) during such four Business Day period (subject to any applicable extensions), which may be on a non-exclusive basis, to permit Parent to propose adjustments to the terms and conditions of this Agreement such that the Alternative Acquisition Agreement ceases to constitute a Superior Proposal; and

(ii) following the four Business Day period (subject to any applicable extensions), the Company Board or any Company Committee shall have determined, in good faith, after consultation with its financial advisors and outside legal counsel, that, in light of such Superior Proposal and taking into account any revised terms proposed in writing by Parent, such Superior Proposal continues to constitute a Superior Proposal and that the failure to make such Adverse Recommendation Change or to terminate this Agreement in accordance with Section 7.1(c)(ii), as applicable, would be inconsistent with the directors’ fiduciary duties under applicable Law.

(e) Notwithstanding anything to the contrary set forth in this Section 5.3 or any other provision in this Agreement to the contrary, upon the occurrence of any Intervening Event, the Company Board or any Company Committee, at any time prior to the adoption of this Agreement by the Required Company Stockholder Approval, may make an Adverse Recommendation Change if all of the following conditions are met:

(i) the Company shall have (A) provided to Parent four Business Days’ prior written notice, which shall (1) set forth in reasonable detail information describing the Intervening Event and (2) state expressly that, subject to clause (ii) below, the Company Board or any Company Committee has determined to make an Adverse Recommendation Change and (B) prior to making such an Adverse Recommendation Change, to the extent Parent has made a request in writing to the Company to engage, negotiated and engaged in good faith with Parent, and shall have caused its

A-35

TABLE OF CONTENTS

directors, officers and employees to have, and shall have instructed and used commercially reasonable efforts to cause its other Representatives to have, negotiated and engaged in good faith with Parent, during such four Business Day period (subject to any applicable extensions) to consider any adjustments proposed by Parent to the terms and conditions of this Agreement such that the failure of the Company Board or any Company Committee to make an Adverse Recommendation Change in response to the Intervening Event in accordance with clause (ii) below would no longer be inconsistent with the Company Board’s fiduciary duties under applicable Law; and

(ii) following the four Business Day period, the Company Board or any Company Committee shall have determined in good faith, after consultation with its outside legal counsel, that in light of such Intervening Event and taking into account any revised terms proposed in writing by Parent, the failure to make an Adverse Recommendation Change would be inconsistent with the directors’ fiduciary duties under applicable Law.

(f) During the Applicable Period, the Company shall (i) promptly (and in any event within 24 hours after receipt of an Acquisition Proposal or any request for information or inquiry that would reasonably be expected to lead to an Acquisition Proposal) advise Parent in writing of any Acquisition Proposal or any request for information or inquiry that would reasonably be expected to lead to an Acquisition Proposal received by the Company or any of its Representatives and the material terms and conditions of any such Acquisition Proposal, request or inquiry (including, for the avoidance of doubt, the identity of the third party making such Acquisition Proposal, request or inquiry), and (ii) keep Parent reasonably informed, on a reasonably prompt basis (and in any event within 24 hours of any material development or material communication) of the status and material details (including material amendments or proposed material amendments) of any such Acquisition Proposal, request or inquiry (and provide Parent with a copy of any such written Acquisition Proposal and copies of any material written materials related thereto exchanged between the Company and such Person and/or their Representatives regarding such Acquisition Proposal or inquiry that would reasonably be expected to lead to an Acquisition Proposal).

(g) Nothing set forth in this Agreement shall prevent the Company or the Company Board or any Company Committee from (i) disclosing to the stockholders of the Company any “stop, look and listen” communication pursuant to Rule 14d-9(f) promulgated under the Exchange Act, or (ii) taking and disclosing to Company stockholders such other position or disclosure contemplated by Rule 14e-2(a), Rule 14d-9 or Item 1012(a) of Regulation M-A promulgated under the Exchange Act (or any similar communication to equity holders in connection with the making or amendment of a tender offer or exchange offer), or (iii) making any disclosure to the Company’s stockholders if, in the good faith judgment of the Company Board or any Company Committee, after consultation with its outside legal counsel, failure to do so would be inconsistent with its fiduciary duties under, or violate, applicable Law; provided, that any “stop, look and listen” statement, or any such similar statement also includes an express reaffirmation of the Company Board Recommendation. For the avoidance of doubt, this Section 5.3(g) shall not permit the Company Board or any Company Committee to make (or otherwise modify the definition of) an Adverse Recommendation Change.

Section 5.4 Access to Information; Confidentiality.

(a) During the Applicable Period, upon reasonable prior written notice, the Company shall, and shall cause its Subsidiaries, officers and directors to, and shall instruct and use commercially reasonable efforts to cause its other Representatives to (i) afford to Parent reasonable access during normal business hours, consistent with applicable Law and the Confidentiality Agreement, to its properties, offices, other facilities, books and records and appropriate officers and employees, and (ii) furnish Parent with all financial, operating and other data and information relating to the Company Group as Parent shall reasonably request in writing, in each case subject to the limitations set forth in this Section 5.4.

(b) Notwithstanding anything to the contrary contained herein, but subject to Section 5.13(d), the Confidentiality Agreement, dated as of May 2, 2025, between Parent (or an Affiliate thereof) and the Company (the “Confidentiality Agreement”) shall remain in full force and effect in accordance with its terms until the Closing and thereafter shall terminate and be of no further force and effect.

(c) From the date hereof until the Closing, without the Company’s prior written consent, each of Parent and Merger Sub shall not, and each shall cause its Affiliates and Representatives not to, contact any employees, independent contractors, customers, vendors, suppliers, or distributors of, or other third parties having business relationships with, the Company Group, other than in the ordinary course of Parent or its Affiliates’ businesses where such contact does not relate to the Company Group, this Agreement, or the Transactions and is in any event conducted in compliance with the terms of the Confidentiality Agreement.

This Section 5.5 shall not apply to any filings, submissions, notifications (or drafts thereof) required under Antitrust Laws or Foreign Investment Laws, which shall be governed by Section 5.6.

(f) Parent and Merger Sub shall not, and shall cause their respective controlled Affiliates not to, enter into any Contract, transaction, agreement, arrangement or understanding to effect any transaction if such Contract or transaction would reasonably be expected to (i) impose any material delay in the obtaining of, or materially increase the risk of not obtaining, any consent, approval, authorization, qualification or order from a Governmental Entity necessary for the consummation of the Transactions or the expiration or termination of any applicable waiting period under any Antitrust Law or Foreign Investment Law, (ii) materially increase the risk of any Governmental Entity entering an injunction, temporary restraining order or other order that would prohibit or delay the consummation of the Transactions under any Antitrust Law or Foreign Investment Law, or (iii) materially increase the risk of not being able to remove any such injunction or order on appeal or otherwise.

(g) Notwithstanding anything to the contrary in this Agreement, the obligations of Parent and Merger Sub under this Section 5.6 shall include Parent and Merger Sub using their respective reasonable best efforts in committing to (and causing their respective Subsidiaries to commit to): (i) enter into any settlement, undertaking, consent decree, stipulation or agreement with or required by any Governmental Entity in connection with the Transactions; (ii) sell, divest, or otherwise convey any asset, category, portion or part of an asset or business of the Company Group, contemporaneously with or subsequent to the Effective Time; (iii) permit the Company Group to sell, divest, or otherwise convey any of the particular assets, categories, portions or parts of assets or businesses of the Company Group prior to the Effective Time; and (iv) license, hold separate (through the establishment of a trust or otherwise) or enter into similar arrangements or conduct restrictions with respect to its respective assets or the assets of the Company Group or the conduct of business arrangements or terminate any existing relationships and contractual rights and obligations; (v) obtain prior approval or other approval from a Governmental Entity, or submit a notification or otherwise notify any Governmental Entity, prior to consummating any future transaction (other than the Transactions) as a condition to obtaining any and all expirations of waiting periods under the HSR Act (or other Antitrust Laws or Foreign Investment Laws) or consents from any Governmental Entity necessary to consummate the Transactions; and (vi) otherwise take, or commit to take, actions after the Effective Time that are purely administrative in nature with respect to Parent, Merger Sub, the Company, the Surviving Corporation or any of their controlled Affiliates; provided, that Parent, on the one hand, and the Company Group, on the other hand, shall not be

A-39

TABLE OF CONTENTS

obligated to take any such actions (A) unless the taking of such action is conditioned upon the occurrence of the Effective Time, (B) if such action would reasonably be expected to have a material adverse effect on the value of the Transactions to Parent or (C) if such action would reasonably be expected to materially and adversely impact the day-to-day business of Parent and its Subsidiaries (including the offering, selling, licensing, marketing, promoting or use of any products or services of Parent and its Subsidiaries) as conducted as of the date of this Agreement (any such action described in clauses (B) or (C) of this proviso, a “Remedial Restriction”). Notwithstanding anything to the contrary in this Section 5.6, other than any actions that are purely administrative in nature, in no event shall Parent be obligated to take, or commit to take, any actions that limit Parent’s freedom of action with respect to, or its ability to retain or exercise rights of ownership or control with respect to, entities, businesses, divisions, operations, products or product lines, assets, Intellectual Property or businesses of Parent and its Subsidiaries, other than, after the Effective Time, the Company Group.

(h) Notwithstanding anything to the contrary in this Section 5.6, any materials exchanged in connection with this Section 5.6 may be redacted as necessary to address reasonable privilege or confidentiality concerns, and to remove references concerning valuation or other competitively sensitive material, and the Parties may, as they deem advisable and necessary, designate any materials provided to the other under this Section 5.6 as “outside counsel only.”

(i) Without limiting Parent’s and Merger Sub’s other obligations under this Section 5.6, Parent shall (acting reasonably and in good faith) be entitled to direct the defense of this Agreement and the Transactions before any Governmental Entity and take the lead in the scheduling of, and strategic planning for, any meetings with, and the conducting of negotiations with, Governmental Entities regarding (i) the expiration or termination of any applicable waiting period relating to the Transactions under any Antitrust Laws or Foreign Investment Laws, or (ii) obtaining any consent, approval, waiver, clearance, authorization or permission from a Governmental Entity, in each case so long as Parent consults (A) in advance with the Company and in good faith takes the Company’s views into account regarding the overall strategic direction of any such defense, meetings or negotiations and (B) with the Company prior to taking any material substantive positions, making dispositive motions or other material substantive filings or submissions or entering into any negotiations concerning such defense, meetings or negotiations.

Section 5.7 Employee Matters.

(a) Without limiting any additional rights that any current or former employee of the Company or any of its Subsidiaries (each, a “Company Employee”) may have under any Company Benefit Plan or applicable Law, and except as otherwise agreed in writing between Parent and a Company Employee, Parent will cause the Surviving Corporation and each of its Subsidiaries, as applicable, for a period commencing at the Effective Time and ending on the first anniversary thereof (or such earlier date of the Company Employee’s termination of employment), to maintain for each Company Employee (i) cash compensation levels (such term to include salary, base wage rate, target bonus opportunities, commission opportunities and severance, but not to include retention, transaction, or change in control compensation) that are each no less favorable than those provided or made available to such Company Employee, or to which such Company Employee had a legally binding right (whether or not subject to any conditions) as of immediately prior to the Effective Time, and (ii) employee benefits (excluding defined benefit plans, retiree welfare arrangements, deferred compensation, equity and equity-based compensation long term incentives, retention, transaction, or change in control compensation) that are in the aggregate no less favorable than the employee benefits provided to similarly situated employees of Parent and its Subsidiaries.

(b) As of and after the Effective Time, Parent will, or will cause the Surviving Corporation to, give each Company Employee full credit for purposes of eligibility, vesting, and benefit accruals (but not for purposes of benefit accruals under any defined benefit pension plans) under each employee benefit (including vacation) plan, program, policy, and arrangement maintained as of and after the Effective Time by Parent, any of its Subsidiaries, or the Surviving Corporation (each, a “Parent Plan”) for the Company Employee’s service with the Company, its Subsidiaries, and their predecessor entities to the same extent recognized by the Company Group under the comparable Company Benefit Plan immediately prior to the Effective Time; provided, that the foregoing shall not apply (A) to the extent that

A-40

its application would result in a duplication of benefits, (B) for any purpose under any retiree welfare arrangement or incentive compensation plan, (C) for purposes of any Parent Plan under which similarly situated employees of Parent and its Subsidiaries do not receive credit for prior service with Parent and its Subsidiaries, or (D) for purposes of any Parent Plan that is grandfathered or frozen, either with respect to level of benefits or participation. With respect to each Parent Plan that is a “welfare benefit plan” (as defined in Section 3(1) of ERISA), Parent and its Subsidiaries will use commercially reasonable efforts to (i) cause there to be waived any pre-existing condition or eligibility limitations and (ii) give effect, in determining any deductible and maximum out-of-pocket limitations, to claims incurred and amounts paid by, and amounts reimbursed to, Company Employees under similar plans maintained by the Company Group immediately prior to the Effective Time during the applicable plan year as if such claim was incurred under or amount was paid or reimbursed by such Parent Plan.

(c) With respect to the Company’s fiscal year in which the Closing occurs, Parent shall, or shall cause one of its Affiliates (including, following the Effective Time, the Surviving Corporation) to, pay, pursuant to each Company Benefit Plan that is a bonus or incentive plan (the “Bonus Plans”), a bonus to each Company Employee who is a Bonus Plan participant, that is equal to the greater of (x) 100% of such Company Employee’s target bonus for such year and (y) such Company Employee’s bonus amount earned based on actual performance for such fiscal year in accordance with such Bonus Plan, in either case at such time as bonuses paid under the Bonus Plans are paid in the ordinary course of business consistent with past practice.

(d) If Parent so requests in writing at least ten Business Days prior to the Closing Date, the Company shall deliver or cause to be delivered to Parent duly adopted resolutions of the Company or its Subsidiary, as applicable, that (i) terminate each Company Benefit Plan intended to be qualified under Section 401(a) of the Code (the “401(k) Plan”), (ii) amend or authorize the amendment of the 401(k) Plan as necessary to bring it current with all applicable legally required plan amendments, and (iii) fully vest all participants under the 401(k) Plan, in each case, effective no later than the Business Day preceding the Closing Date, in each case, in compliance with the terms of such 401(k) Plan and the requirements of applicable Law.

(i) Within 30 calendar days following the date hereof, the Company shall provide a list of all individuals who are employees of the Company or any of its Subsidiaries as of the date hereof, including any employee who is on a leave of absence of any nature, paid or unpaid, authorized or unauthorized, and sets forth for each such individual the following, in each case, to the extent that disclosure is allowed under to applicable Laws: (A) name (or anonymous identifier if required by applicable Laws), (B) employing entity, (C) work location (by country, state/province and city), (D) title or position (including whether full time or part time), (E) hire date, (F) current annual salary or base hourly rate of pay, (G) eligibility for commission, bonus or other incentive based compensation, (H) amount of accrued and unused vacation and sick time for current calendar year (for U.S. employees only), (I) whether classified as overtime exempt or non-exempt (for U.S. employees only), and (J) whether employed on an at-will basis (for U.S. employees only) (the “Employee Census”).

Section 5.9 Indemnification, Exculpation and Insurance.

(a) Except as may be required by applicable Law, Parent and the Company agree that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the Effective Time (whether asserted or claimed prior to, at or after the Effective Time) and rights to advancement of expenses relating thereto now existing in favor of any present (as of the Effective Time) and former officer and director of any member of the Company Group and each other Person who is as of the date of this Agreement, or who thereafter commences prior to the Effective Time, serving at the request of any member of the Company Group as a director or officer of another Person (the “Indemnified Parties”), as provided in the certificate of incorporation or bylaws (or comparable organizational documents) of the Company Group or in any indemnification agreement between such Indemnified Party and the Company Group made available to Parent prior to the date hereof shall survive the Merger and continue in full force and effect, and shall not be amended, repealed or otherwise modified in any manner that would adversely affect any right thereunder of any such Indemnified Party and shall be assumed by the Surviving Corporation in the Merger, without further action, at the Effective Time.

(b) For a period of six years from the Effective Time, Parent shall cause the Surviving Corporation to, at Parent’s sole election, (i) cause to be maintained in effect the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company Group, (ii) cause to be provided substitute policies or (iii) purchase a “tail policy,” in each case of the foregoing clauses (i) through (iii), of at least the same coverage and amounts and containing other terms and conditions that are not less advantageous in the aggregate than the directors’ and officers’ liability insurance coverage and fiduciary liability insurance currently maintained by the Company Group with respect to claims arising from facts or events that occurred at or before the Effective Time (with insurance carriers having at least an “A” rating by A.M. Best with respect to directors’ and officers’ liability insurance); provided, that after the Effective Time, the Surviving Corporation shall not be required to pay with respect to such

A-42

TABLE OF CONTENTS

insurance policies in respect of any one policy year annual premiums in excess of 300% of the last annual premium paid by the Company prior to the date hereof in respect of the coverage required to be obtained pursuant hereto, but in such case shall purchase as much coverage as reasonably practicable for such maximum amount; provided, further, that if the Surviving Corporation elects to purchase an insurance policy and the annual coverage thereunder costs more than 300% of such last annual premium, the Surviving Corporation shall purchase the maximum amount of annual coverage that can be obtained for 300% of such last annual premium. At the Company’s option, the Company may purchase, prior to the Effective Time, a six-year prepaid “tail policy” on terms and conditions (in both amount and scope) providing substantially equivalent benefits as the current policies of directors’ and officers’ liability insurance and fiduciary liability insurance maintained by the Company Group with respect to matters arising on or before the Effective Time, covering without limitation the Transactions. If such prepaid tail policy has been obtained by the Company prior to the Effective Time, Parent shall cause such policy to be maintained in full force and effect, for its full term, and cause all obligations thereunder to be honored by the Surviving Corporation.

(c) In the event that the Surviving Corporation or Parent or any of their respective successors or assigns (i) consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers, conveys or disposes of all or a majority of its properties and assets to any Person or engages in any division transaction, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation or Parent, as the case may be, shall succeed to the obligations set forth in this Section 5.9.

(d) The indemnification provided for herein shall not be deemed exclusive of any other rights to which an Indemnified Party is entitled, whether pursuant to Law, Contract or otherwise.

Section 5.10 Rule 16b-3. Prior to the Effective Time, the Company will take such steps as may be reasonably necessary or advisable hereto to cause dispositions of Company equity securities (including derivative securities) pursuant to the Transactions by each individual who is a director or officer of the Company to be exempt under Rule 16b-3 promulgated under the Exchange Act.

Section 5.11 Public Announcements. The initial press release announcing the execution and delivery of this Agreement shall be a joint release of Parent and the Company. Following such initial press release, each of Parent (or its applicable Affiliate) and the Company shall reasonably consult with each other before issuing, and give each other a reasonable opportunity to review and comment upon, any press release or other public statement with respect to this Agreement and the Transactions and shall not issue any such press release or make any public announcement without the prior consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed, except (a) as may be required by applicable Law, court process or by obligations pursuant to any listing agreement with, or rule or regulation of, any national securities exchange or national securities quotation system if such Party has, to the extent permitted by applicable Law, used its commercially reasonable efforts to consult with the other Party hereto, and given good faith consideration to any input received, prior to the time such disclosure is so required to be issued, (b) with respect to an Acquisition Proposal or Adverse Recommendation Change made in accordance with this Agreement, (c) to enforce rights and remedies under this Agreement, and (d) the Company may make any press release, public statement or filing to be issued or made pursuant to Section 5.3(g); provided that the foregoing shall not apply to any public statement, disclosure, or communication so long as such statement, disclosure, or communication is substantially similar in tone and substance with previous public statements, disclosures, or communications made by the Company or Parent, as applicable, or to the extent that they have been reviewed and previously approved by both the Company and Parent. Notwithstanding the foregoing provisions of this Section 5.11, subject to the terms and conditions of the Confidentiality Agreement, (i) Parent, Merger Sub and the Financing Sources may make customary announcements and communications in connection with the arrangement of the Debt Financing to the extent permitted by Section 5.13(d), and (ii) any Affiliate of Parent that is a private equity or other investment fund or investment vehicle, or any manager or general partner of any such fund or investment vehicle, may, in the ordinary course of business and to the extent necessary in connection with its customary fundraising, marketing, informational or reporting activities, on a confidential basis, report and disclose to its partners, investors, potential investors or similar parties, general information regarding this Agreement and the Transactions, in each case subject to customary obligations of confidentiality with respect to non-public information.

(b) During the Applicable Period, Parent and Merger Sub shall give the Company prompt (but in any event within two (2) Business Days) written notice of (A) any material breach, default, cancellation, termination or any repudiation or threatened or anticipated material breach, default, cancellation, termination or any anticipated repudiation by any party to the Commitment Letters or any other agreements, documents or instruments (including any definitive agreements relating thereto) relating to the Financing of which Parent or its Affiliates becomes aware, and (B) the receipt by Parent or Merger Sub or any of their respective Affiliates of any written notice or other written communication from any Person with respect to any actual or potential breach, default, termination, cancellation, or repudiation by any party to any Commitment Letter or other agreements, documents or instruments (including any definitive agreements relating thereto) relating to the Financing. Without limiting Parent’s other obligations under this Section 5.14, if for any reason all or any portion of the Financing becomes unavailable or would reasonably be expected to become unavailable (including as a result of repudiation, expiration or termination of any portion of the commitments set forth in the Commitment Letters or a breach or default by any of the Financing Sources) on the terms, in the manner, or from the sources contemplated by any Commitment Letter or any other agreement, document or instrument relating to the Financing and the portion of the Financing that remains available, together with Available Cash, then Parent and Merger Sub shall (i) promptly (but in any event within two (2) Business Days) notify the Company in writing thereof and the reasons therefor, (ii) use commercially reasonable efforts to obtain, arrange and consummate alternative financing from alternative Financing Sources (on terms containing no new, additional or more onerous conditions to the consummation of such financing relative to the Financing Conditions or any other Prohibited Modifications) reasonably acceptable to Parent acting in good faith that, when taken together with the portion of the Debt Financing that remains available and is not reasonably expected to become unavailable and Available Cash, is at least equal to the Required Amount, as promptly as practicable following the occurrence of such event, and (iii) use commercially reasonable efforts to obtain, and when obtained, provide the Company with a true, correct and complete copy of, a new financing commitment, engagement letter, and related fee letters that provides for such alternative financing subject only to the Financing Conditions; provided, that any provisions set forth in such new financing commitment may be redacted in a manner consistent with the permitted redactions to the Debt Fee Letter provided on or prior to the date of this Agreement, so long as such redaction does not extend to any terms that would reasonably be expected to impose any Prohibited Modification; provided, further, that, in no event shall commercially reasonable efforts be construed to require that

Parent (A) pay any fees or original issue discount in excess of those contemplated by the Debt Commitment Letter and the Debt Fee Letter as in effect on the date hereof or (B) agree to pricing or other economic terms that are less favorable (taken as a whole) than those contemplated by the Debt Commitment Letter and the Debt Fee Letter as in effect on the date hereof (in each case of clauses (A) and (B), assuming the full exercise of any “market flex” provisions in the Debt Commitment Letter).

(c) During the Applicable Period, without the prior written consent of the Company, Parent and Merger Sub shall not amend, modify, supplement, restate, assign, substitute or replace the Equity Commitment Letter, Debt Commitment Papers or any Debt Financing Document or substitute other debt or equity financing for all or any portion of the Financing, except, solely in the case of the Debt Commitment Papers, the Debt Financing Documents and any substitution of other debt financing for all or any portion of the Debt Financing, if such amendment, modification, supplement, restatement, assignment, substitution or replacement would not, and would not reasonably be expected to, (i) impose new or additional conditions precedent or expand upon (or amend or modify in any manner) the conditions precedent to the funding of the Debt Financing, (ii) reduce the net cash amount of the Debt Financing (including by increasing the amount of fees to be paid) to an amount that, together with Available Cash, is less than the Required Amount, (iii) materially impair, delay or prevent the consummation of the Financing or the other Transactions contemplated to occur under this Agreement on the Closing Date (taking into account the timing of the Marketing Period), or (iv) adversely affect Parent’s or Merger Sub’s ability to consummate the Transactions; provided, that Parent may, without the prior written consent of the Company, amend, modify, supplement, restate, assign, substitute or replace the Debt Commitment Letter to (A) add and appoint additional arrangers, bookrunners, underwriters, agents, lenders and similar entities, to provide for the assignment and reallocation of a portion of the financing commitments contained therein and to grant customary approval rights to such additional arrangers and other entities in connection with such appointments, (B) modify pricing and/or (C) increase the aggregate amount of the Debt Financing, in each case, so long as such amendments would not be reasonably expected to materially impair, delay or prevent the consummation of the Transactions on the Closing Date (taking into account the timing of the Marketing Period) or adversely affect Parent’s or Merger Sub’s ability to consummate the Transactions on or prior to the Termination Date. Upon request of the Company, Parent and Merger Sub shall keep the Company informed in reasonable detail of the status of Parent’s and Merger Sub’s efforts to obtain the Financing and to satisfy the conditions thereof. Parent and Merger Sub expressly acknowledge and agree that their obligations under this Agreement, including their obligations to consummate the Merger and the other Transactions, are not subject to, or conditioned on, Parent’s or Merger Sub’s receipt of financing. Any alternative, substitute or replacement debt financing obtained by Parent in accordance with this Section 5.14 is the “Alternative Financing.” For purposes of this Agreement, references to “Debt Financing” shall include the financing contemplated by any Alternative Financing and references to “Debt Commitment Letter,” “Debt Fee Letter,” “Debt Financing Documents” or “Financing Sources” shall include the documents (or commitments or financing sources, as applicable) in connection with any Alternative Financing to the extent permitted by this Section 5.14, and such Alternative Financing shall be required to comply with the provisions of this Agreement to the same extent as the Debt Financing.

At Parent’s written request during the Applicable Period, the Company shall use its commercially reasonable efforts to (i) facilitate the delivery of a substantially complete draft of the Payoff Letter at least three (3) Business Days prior to Closing and the final Payoff Letter at least one (1) Business Day prior to Closing (in each case, or such later date as Parent may agree), and (ii) reasonably cooperate with any back-stop, “roll-over” or termination of any existing letters of credit under the Company Credit Agreement; provided that, the Parties acknowledge and agree that Parent shall be responsible for paying all amounts under the Payoff Letter, including by cash collateralizing, backstopping or repaying any letters of credit or similar obligations. Contemporaneously with the Closing, Parent and Merger Sub shall pay (or cause to be paid) to the lenders under the Company Credit Agreement the amount specified in the Payoff Letter (including after giving effect to any per diem amount specified therein, to the extent applicable) in cash in immediately available funds to the bank account(s) specified therein to discharge all liabilities and obligations of the Company Group outstanding under the Company Credit Agreement (including the release and discharge of all related guarantees, liens and security interests) and to terminate the commitments thereunder (such payoff, the “Company Debt Payoff”).

Each of the Parties shall use their respective commercially reasonable efforts to respond promptly to any comments or requests from the SEC (or the staff of the SEC) with respect to the Proxy Statement. The Company shall use its commercially reasonable efforts so that the Proxy Statement will comply as to form in all material respects with the provisions of the Exchange Act and the rules and regulations promulgated thereunder. Prior to filing or mailing the Proxy Statement (or any amendment or supplement thereto) or responding to any comments or requests from the SEC (or the staff of the SEC) with respect thereto, to the extent permitted by applicable Law, the Company shall provide Parent a reasonable opportunity to review and to propose comments on such document or response and the Company shall consider in good faith the inclusion or reflection of any such reasonable comments so provided; provided, that the Company may amend or supplement the Proxy Statement without the review or comment of Parent to the extent required to effect an Adverse Recommendation Change pursuant to and in accordance with Section 5.3. The Company agrees that none of the information supplied by it or its Subsidiaries for inclusion in the Proxy Statement shall, at the date the Proxy Statement is filed with the SEC or first mailed to the Company’s stockholders or at the time of the Company Stockholder Meeting or at the time of any amendment or supplement thereto, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, that notwithstanding the foregoing, no covenant is made by the Company with respect to any information supplied by Parent, Merger Sub or any of their Affiliates or Representatives, or any of the Financing Sources, expressly for inclusion or incorporation by reference in the Proxy Statement.

(b) Parent and Merger Sub shall (i) as promptly as possible, furnish to the Company all information concerning Parent and Merger Sub that is required to be included in the Proxy Statement by the Exchange Act and the rules and regulations promulgated thereunder, that is customarily included in proxy statements prepared in connection with transactions of the type contemplated by this Agreement, as otherwise required by applicable Law or requested by the SEC, or that may be reasonably requested by the Company in connection with the Proxy Statement, and (ii) shall otherwise use commercially reasonable efforts to assist and cooperate with the Company and its Representatives in the preparation of the Proxy Statement and the resolution of comments from the SEC (or the staff of the SEC). Parent agrees that none of the information supplied by Parent, Merger Sub or their respective Affiliates for inclusion in the Proxy Statement shall, at the date the Proxy Statement is filed with the SEC or first mailed to the Company’s stockholders or at the time of the Company Stockholder Meeting or at the time of any amendment or supplement thereto, contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading; provided, that notwithstanding the foregoing, no covenant is made by Parent with respect to any information supplied by Parent, Merger Sub or any of their Affiliates or Representatives, or any of the Financing Sources, expressly for inclusion

or incorporation by reference in the Proxy Statement. Parent shall confirm and/or supplement the information relating to Parent or Merger Sub supplied by it for inclusion in the Proxy Statement, such that at the time of the mailing of the Proxy Statement or any amendments or supplements thereto, and at the time of the Company Stockholder Meeting, such information shall not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading.

(c) In accordance with the Company’s organizational documents, unless this Agreement is validly terminated pursuant to Section 7.1, the Company shall use commercially reasonable efforts to, as promptly as reasonably practicable after the date of this Agreement (but subject to the last sentence of this Section 5.17(c) and the timing contemplated in Section 5.17(a)), (x) establish a record date for and give notice of a meeting of its stockholders, for the purpose of voting upon the adoption of this Agreement (including any adjournment or postponement thereof, the “Company Stockholder Meeting”), and (y) mail a Proxy Statement to the holders of Shares as of the record date established for the Company Stockholder Meeting (such date, the “Proxy Date”). Without the prior written consent of Parent (not to be unreasonably withheld, conditioned or delayed), in no event shall the Proxy Date be changed to such a date that would result in the Company Stockholder Meeting being within ten Business Days of the Initial Termination Date, except as required by applicable Law. Without the prior written consent of Parent, the adoption of this Agreement shall be the only matter (other than matters of procedures and matters required by applicable Law to be voted on by the Company’s stockholders in connection with the adoption of this Agreement, including any advisory vote regarding merger-related compensation and a customary proposal regarding adjournment of the Company Stockholder Meeting) that the Company shall propose to be acted on by the stockholders of the Company at the Company Stockholder Meeting. Subject to the earlier termination of this Agreement in accordance with Section 7.1, the Company shall use commercially reasonable efforts to duly call, convene and hold the Company Stockholder Meeting as promptly as reasonably practicable after the Proxy Date (with the Company Stockholder Meeting in no event being initially scheduled for a date later than the 45th calendar day following the first mailing of the Proxy Statement to the Company’s stockholders); provided, that the Company may postpone, recess, reschedule, or adjourn the Company Stockholder Meeting: (i) with the consent of Parent (not to be unreasonably withheld, conditioned or delayed), (ii) for the absence of a quorum (it being understood that the Company may not postpone or adjourn the Company Stockholder Meeting (x) more than two times pursuant to this clause (ii) or (y) for more than ten Business Days in the aggregate, in each case, without Parent’s prior written consent), (iii) to solicit additional proxies for the purposes of obtaining the Required Company Stockholder Approval (it being understood that the Company may not postpone or adjourn the Company Stockholder Meeting (x) more than two times pursuant to this clause (iii) or (y) for more than ten Business Days in the aggregate, in each case, without Parent’s prior written consent), (iv) to allow reasonable additional time for the filing and distribution of any supplement or amendment to the Proxy Statement or other supplemental or amended disclosure which the Company Board has determined in good faith (after consultation with its outside legal counsel) is necessary under applicable Laws and for such supplemental or amended disclosure to be disseminated to and reviewed by the Company’s stockholders prior to the Company Stockholder Meeting, and (v) if determined in good faith by the Company Board, after consultation with its legal counsel, such adjournment, recess, delay or postponement is required under applicable Law or is reasonably necessary to comply with a request from the SEC or its staff. Unless the Company Board shall have effected an Adverse Recommendation Change pursuant to Section 5.3, (x) on no more than two occasions and prior to the vote contemplated having been taken, if the Company has not received proxies sufficient to obtain the Required Company Stockholder Approval, then Parent shall have the right to require an adjournment or postponement of the Company Stockholder Meeting for the purpose of soliciting additional votes in favor of this Agreement; provided, that no such individual adjournment or postponement shall delay the Company Stockholder Meeting by more than seven days from the prior-scheduled date or to a date on or after the fifth Business Day preceding the Initial Termination Date, and (y) the Company shall use its commercially reasonable efforts to solicit proxies in favor of the adoption of this Agreement. Notwithstanding anything to the contrary contained in this Agreement and notwithstanding any Adverse Recommendation Change, the Company shall submit this Agreement to the stockholders of the Company for adoption at the Company Stockholder Meeting; provided, that such obligations shall immediately and automatically terminate and the Company shall not be required to hold the Company Stockholder Meeting if this Agreement is terminated in accordance with Article VII.

TABLE OF CONTENTS

Company, or otherwise publicly disclosed or otherwise made known to the stockholders of the Company and not withdrawn at least three Business Days prior to such termination under Section 7.1(b)(i) or Section 7.1(d)(i), or at least three Business Days prior to such vote to adopt this Agreement, as applicable, and (B) within one year after such termination, the Company shall have entered into a definitive agreement with respect to an Acquisition Proposal (regardless of when made or the counterparty thereto) that is subsequently consummated (it being understood that such consummation may occur after the one year period after this Agreement is terminated) (provided; that for purposes of this Section 7.3(b)(i)(1), the references to “20% or more” in the definition of Acquisition Proposal shall be deemed to be references to “more than 50%”);

(2) this Agreement is terminated by the Company pursuant to Section 7.1(c)(ii); or

(3) this Agreement is terminated by Parent pursuant to Section 7.1(d)(ii);

then, in any such case, the Company shall pay to Parent a termination fee of $60,000,000 (the “Company Termination Fee”). In no event shall the Company be required to pay (or cause any of its Subsidiaries or Affiliates to pay) the Company Termination Fee on more than one occasion.

(ii) Payment of the Company Termination Fee, if applicable, shall be made by wire transfer of same-day funds to the account or accounts designated by Parent (i) prior to, or on, the consummation of any transaction contemplated by an Acquisition Proposal, in the case of a Company Termination Fee payable pursuant to Section 7.3(b)(i)(1), (ii) prior to, or concurrently with, termination in the case of a Company Termination Fee payable pursuant to Section 7.3(b)(i)(2), or (iii) as promptly as reasonably practicable, but in any event within three Business Days, after termination, in the case of a Company Termination Fee payable pursuant to Section 7.3(b)(i)(3).

(iii) Each Party acknowledges that the agreements contained in this Section 7.3 are an integral part of the Transactions, and that, without these agreements, the Parties would not enter into this Agreement; accordingly, if the Company fails to timely pay any amounts due pursuant to this Section 7.3, and, in order to obtain such payment, Parent commences a suit that results in a judgment against the Company for the amounts set forth in this Section 7.3, the Company shall pay to Parent its reasonable and documented out-of-pocket costs and expenses (including reasonable and documented out-of-pocket attorneys’ fees and expenses), together with interest (compounded annually) on the amounts due pursuant to this Section 7.3 from the date such payment was required to be made until the date of payment at the prime lending rate as published in The Wall Street Journal in effect on the date such payment was required to be made, which interest amount shall be calculated daily on the basis of a 365 day year (collectively, “Recovery Costs”); provided, that, (i) in no event shall any Recovery Costs payable under this Section 7.3(b) exceed an aggregate amount equal to $7,500,000; and (ii) in no event shall attorneys’ fees that are based on a contingency fee, “success” fee or any other type of fee arrangement dependent on the outcome of the suit be deemed to be reasonable attorneys’ fees incurred by Parent in connection with any suit referred to in this Section 7.3(b)(iii).

(iv) Each Party further acknowledges that the Company Termination Fee is not a penalty, but rather is liquidated damages in a reasonable amount that will compensate Parent and Merger Sub in the circumstances in which the Company Termination Fee is payable for the efforts and resources expended and opportunities foregone while negotiating this Agreement and in reliance on this Agreement and on the expectation of the consummation of the Transactions.

(v) Subject to Section 7.3(d), the Parties agree that the payment of the Company Termination Fee and, if applicable, the Recovery Costs of Parent pursuant to Section 7.3(b)(iii) (in each case, solely to the extent fully paid), shall be the sole and exclusive monetary remedy available to Parent, Merger Sub or any of their respective Affiliates under or related to this Agreement (and the termination hereof), the Transactions (including the failure thereof to be consummated) or any matter forming the basis for such termination in the event any such payment becomes due and payable, and none of Parent, Merger Sub or any of their respective Affiliates shall be entitled to bring or maintain any Action against any Company Related Party arising out of or in connection

with this Agreement, any of the Transactions or any matters forming the basis for such termination. Subject to Section 7.3(d), upon payment of the Company Termination Fee (and Recovery Costs, if applicable) by the Company, neither the Company, nor its Subsidiaries or Affiliates, nor any of their respective former, current or future stockholders, optionholders, controlling Persons, managers, members, directors, officers, employees, partners, Affiliates, Representatives, agents nor any of their respective assignees or successors nor any former, current or future stockholder, optionholder, controlling Person, manager, member, director, officer, employee, partner, Affiliate, Representative, agent, assignee or successor of any of the foregoing (collectively, the “Company Related Parties”) shall have any further liability to Parent, Merger Sub or any other Person for any losses suffered under, arising out of or relating to this Agreement and the Transactions or any matters forming the basis for such termination (including the termination hereof and the abandonment of the Merger), whether at law, in contract, in tort, in equity or otherwise. Nothing in this Section 7.3(b)(v) shall in any way expand or be deemed or construed to expand the circumstances in which the Company or any Company Related Party may be liable under this Agreement or in connection with the Transactions.

(i) In the event that this Agreement is terminated (A) by the Company pursuant to Section 7.1(c)(i) or Section 7.1(c)(iii) (but only if at such time the Company would not be prohibited from terminating this Agreement as a result of the last proviso contained in Section 7.1(c)(i)), or (B) by the Company or Parent pursuant to Section 7.1(b)(i) and at the time of such termination the Company could have terminated this Agreement pursuant to Section 7.1(c)(i) or Section 7.1(c)(iii), then, in any such case, Parent shall pay, or cause to be paid, to the Company a termination fee of $144,000,000 (the “Parent Termination Fee”). In no event shall Parent be required to pay (or cause any of its Subsidiaries or Affiliates to pay) the Parent Termination Fee on more than one occasion.

(ii) Payment of the Parent Termination Fee, if applicable, shall be made by wire transfer of same-day funds to the account or accounts designated in writing by the Company as promptly as reasonably practicable, but in any event within three Business Days, after termination.

(iii) Each Party acknowledges and agrees that the agreements contained in this Section 7.3 are an integral part of the Transactions and do not constitute a penalty, and that, without these agreements, the Parties would not enter into this Agreement; accordingly, if Parent fails to timely pay any amounts due pursuant to this Section 7.3, and, in order to obtain such payment, the Company commences a suit that results in a judgment against Parent for the amounts set forth in this Section 7.3 or the Guarantors under the Limited Guarantee, Parent shall pay to the Company its Recovery Costs (provided, however, in no event shall any Recovery Costs payable under this Section 7.3(c) exceed $7,500,000).

(iv) Subject to Section 7.3(d), the Parties agree that the payment of the Parent Termination Fee and, if applicable, the costs and expenses of the Company pursuant to Section 5.13(e) and the Recovery Costs of the Company pursuant to Section 7.3(c)(iii) (in each case, solely to the extent fully paid), shall be the sole and exclusive monetary remedy available to the Company or any of its stockholders or Affiliates under or related to this Agreement (and the termination hereof), the Transactions (including the failure thereof to be consummated) or any matter forming the basis for such termination in the event any such payment becomes due and payable, and none of the Company, its stockholders or any of their respective Affiliates shall be entitled to bring or maintain any Action against Parent, Merger Sub, the Guarantors, any Financing Related Person or any of their respective former, current or future stockholders, optionholders, controlling Persons, managers, members, directors, officers, employees, partners, Affiliates, Representatives, agents nor any of their respective assignees or successors nor any former, current or future stockholder, optionholder, controlling Person, manager, member, director, officer, employee, partner, Affiliate, Representative, agent, assignee or successor of any of the foregoing (such Persons, the “Parent Parties”) arising out of or in connection with this Agreement, the Commitment Letters, the Limited Guarantee, the Debt Financing, the Debt Financing Documents or any of the Transactions or any matters forming the basis for such termination. Subject to Section 7.3(d), upon payment of the Parent Termination Fee, the costs and expenses of the Company pursuant to Section 5.13(e) and the Recovery Costs of the

A-57

TABLE OF CONTENTS

Company pursuant to Section 7.3(c)(iii) (in each case, solely to the extent fully paid), if applicable, by or on behalf of Parent, none of the Parent Parties nor any Financing Related Person shall have any further liability to the Company or any other Person for any losses suffered under, arising out of or relating to this Agreement, the Debt Financing, the Debt Financing Documents and the Transactions (including the termination hereof and the abandonment of the Merger), whether at law, in contract, in tort, in equity or otherwise. For the avoidance of doubt, while the Company may pursue both a grant of specific performance of the type contemplated by Section 8.10 and the payment of the Parent Termination Fee pursuant to this Section 7.3(c)(iv), as the case may be, under no circumstances shall the Company be permitted or entitled to receive both a grant of specific performance of the type contemplated by Section 8.10 to effect the Closing and payment of the Parent Termination Fee. For the avoidance of doubt, no reimbursement, indemnification, or interest payment pursuant to Section 5.13(e) or Section 7.3(c)(iii) shall reduce the amount of the Parent Termination Fee. Nothing in this Section 7.3 shall restrict (x) the availability to the Company of any remedies in connection with any breach of the Confidentiality Agreement, for which all applicable legal and equitable remedies shall be available to the Company, or (y) the Company’s entitlement to seek and obtain specific performance (1) hereunder as and to the extent permitted by Section 8.10, (2) against the Guarantors under the Limited Guarantee, or (3) under the Equity Commitment Letter to the extent expressly permitted under, and in accordance with, the terms and conditions set forth therein and herein. Nothing in this Section 7.3(c)(iv) shall in any way expand or be deemed or construed to expand the circumstances in which Parent or any other Parent Party may be liable under this Agreement or the Transactions.

(d) Willful Breach. Notwithstanding anything to the contrary in this Agreement (including Section 7.3(b)(v) and Section 7.3(c)(iv)), if this Agreement is validly terminated pursuant to any provision of Section 7.1 and, prior to such termination, there has been a Willful Breach of this Agreement by any Party, then, notwithstanding the payment of, or any obligation to pay, the Company Termination Fee or the Parent Termination Fee, as applicable, the non-breaching party shall also be entitled to seek from the Party that has committed such Willful Breach payment of damages if and when due pursuant to this Agreement; provided that, the Parties hereto acknowledge and agree that in no event shall the maximum aggregate monetary liability of any Party (together with the Parent Parties and Company Parties, as applicable) for any and all losses, liabilities, damages and other amounts arising out of or relating to such Willful Breach under this Agreement exceed an amount equal to (x) $175,000,000, plus (y) the amount of any Recovery Costs, plus (z) in the case of a Willful Breach by Parent, the amount of any the reimbursement and indemnification obligations under Section 5.13(e) of this Agreement, if applicable (the “Willful Breach Liability Limitation”), which amount shall apply in lieu of, and shall supersede, any limitation on liability that would otherwise apply pursuant to Section 7.3(b)(v) or Section 7.3(c)(iv), as applicable. For the avoidance of doubt, any Company Termination Fee, Parent Termination Fee and Recovery Costs actually paid by the breaching Party shall be credited against, and shall reduce on a dollar-for-dollar basis, amounts payable by such Party under this Agreement (up to an amount equal to the Willful Breach Liability Limitation). For the avoidance of doubt, (i) in no event shall any Party be required to pay, in the aggregate, an amount in respect of a Willful Breach in excess of the Willful Breach Liability Limitation, and (ii) nothing in this Section 7.3(d) shall limit the right of any party to seek specific performance or other equitable remedies in accordance with Section 8.10.

Section 7.4 Amendment or Supplement. This Agreement may be amended, modified or supplemented by the Parties, prior to the Effective Time; provided that, following the receipt of the Required Company Stockholder Approval, this Agreement may not be amended in any manner that requires further approval of the stockholders of the Company pursuant to the DGCL without such further stockholder approval. This Agreement may not be amended, modified or supplemented in any manner, whether by course of conduct or otherwise, except by an instrument in writing specifically designated as an amendment hereto, signed on behalf of each of the Parties at the time of the amendment. Notwithstanding anything to the contrary contained herein, the Lender Protective Provisions contained in this Agreement (and, solely as they relate to such Lender Protective Provisions, the definitions of any terms used in such Lender Protective Provisions) may not be amended, waived or otherwise modified in any manner that adversely affects the Debt Financing or any Financing Related Person, or that imposes any additional liabilities or obligations on, or limits any protections afforded to, any Financing Related Person, without the prior written consent of the Financing Sources.

Accordingly, each of the Company (on behalf of itself and on behalf of the holders of Shares as third party beneficiaries under Section 8.6), Parent and Merger Sub acknowledge and agree that, subject in all respects to the terms and limitations set forth in this Section 8.10, (i) at any time prior to the valid termination of this Agreement pursuant to Article VII, the Parties shall be entitled to seek specific performance of the terms of this Agreement, including an injunction or injunctions to prevent breaches of this Agreement to enforce specifically the terms and provisions of this Agreement in the courts chosen under Section 8.8, this being in addition to any other remedy to which such Party is entitled at law or in equity, and (ii) the right of specific performance is an integral part of the Transactions and without that right, neither the Company nor Parent would have entered into this Agreement. Each Party hereby further waives (a) any defense in any action for specific performance that a remedy at law would be adequate or that an award of specific performance is not an appropriate remedy for any reason at law or equity, and (b) any requirement under any law to provide any bond or to post any security as a prerequisite to obtaining equitable relief; provided that, solely with respect to the equitable remedy to specifically enforce Parent’s or Merger Sub’s obligation to effect the Closing, Parent and Merger Sub may oppose the granting of specific performance if one or more of the specific performance conditions set forth below have not been satisfied. Notwithstanding the foregoing it is explicitly agreed that the Company shall only be permitted to obtain an injunction, specific performance or other equitable remedies to enforce the Parent Parties’ obligations to effect the Closing pursuant to Section 1.2

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, Parent and each of the Stockholders hereby agree as follows:

1. Agreement to Vote. During the term of this Agreement, each Stockholder agrees that, with respect to each Covered Share that such Stockholder is entitled to vote, such Stockholder shall, and shall cause any other holder of record of any such Covered Shares to, at any meeting of the stockholders of the Company (whether annual or special and whether or not an adjourned or postponed meeting, or any action by written consent in lieu of a meeting) or in any other circumstances upon which a vote, consent or other approval of the Stockholders is sought: (i) when a meeting concerning the Transactions is held, appear at such meeting or otherwise cause all such Covered Shares to be counted as present thereat for the purpose of establishing a quorum; (ii) vote (or cause to be voted, including by proxy or by delivering a written consent) all such Covered Shares in favor of (x) the Merger and the adoption of the Merger Agreement and each of the other Transactions, (y) any other actions presented at any meeting of the stockholders of the Company (whether annual or special and whether or not an adjourned or postponed meeting, or any action by written consent in lieu of a meeting) that are necessary to consummate the transactions contemplated by the Merger Agreement and (z) the approval of any proposal to adjourn or postpone such meeting to a later date, if there are not sufficient votes for the adoption of the Merger Agreement on the date on which such meeting is held; and (iii) vote (or cause to be voted) all such Covered Shares against any other proposal (including any Acquisition Proposal or Alternative Acquisition Agreement), action or agreement that would reasonably be expected to impede, interfere with, delay, postpone or adversely affect the Merger or any of the Transactions.

Members of the Board and the Special Committee:

We understand that DoubleVerify Holdings, Inc., a Delaware corporation (the “Company”), proposes to enter into an Agreement and Plan of Merger (the “Agreement”), by and among the Company, Neptune Bidco US Inc., a Delaware corporation (“Parent”), and Wallace Merger Sub Inc., a Delaware corporation and a direct, wholly-owned subsidiary of Parent (“Acquisition Sub”), pursuant to which Acquisition Sub will merge with and into the Company (the “Transaction”), with the Company surviving the Transaction as a wholly-owned subsidiary of Parent, and pursuant to the Transaction, each issued and outstanding share of common stock of the Company, par value $0.001 per share(such shares, the “Shares”) (excluding certain shares specified in the Agreement) will be converted into the right to receive an amount in cash equal to $13.60 per share (such consideration, the “Consideration”), without interest and subject to any withholding of taxes required by applicable law. The terms and conditions of the Transaction are fully set forth in the Agreement.

You have asked us for our opinion as to the fairness, from a financial point of view, to the holders of the Shares of the Consideration to be received by such holders in the Transaction. In arriving at the opinion set forth below, we have, among other things:

(i)

reviewed certain publicly available information concerning the business, financial condition and operations of the Company;

(ii)

reviewed certain internal information concerning the business, financial condition and operations of the Company prepared and furnished to us by the management of the Company;

(iii)

(iv)

held discussions with members of senior management of the Company concerning, among other things, their evaluation of the Transaction and the Company’s business, operating and regulatory environment, financial condition, prospects and strategic objectives;

(v)

reviewed the historical market prices and trading activity for the Shares;

(vi)

compared certain publicly available financial and stock market data for the Company with similar information for certain other companies that we deemed to be relevant;

(vii)

compared the proposed financial terms of the Transaction with publicly available financial terms of certain other business combinations that we deemed to be relevant;

TABLE OF CONTENTS

(viii)

reviewed a draft, dated August 6, 2026 of the Agreement; and

(ix)

performed such other financial studies, analyses and investigations, and considered such other matters, as we deemed necessary or appropriate for purposes of rendering this opinion.

In preparing this opinion, with your consent, we have relied upon and assumed the accuracy and completeness of the foregoing information and all other information discussed with or reviewed by us, without independent verification thereof. We have assumed, with your consent, that the Projections and the assumptions underlying the Projections, and all other financial analyses, estimates and forecasts provided to us by the Company’s management, have been reasonably prepared in accordance with industry practice and represent the Company management’s best currently available estimates and judgments as to the business and operations and future financial performance of the Company. We assume no responsibility for and express no opinion as to the Projections, the assumptions upon which they are based or any other financial analyses, estimates and forecasts provided to us by the Company’s management. We have also assumed that there have been no material changes in the assets, financial condition, results of operations, business or prospects of the Company since the respective dates of the last financial statements made available to us. We have relied, with your consent, on the Company management’s representations and/or projections regarding taxable income, standalone net operating loss utilization and other tax attributes of the Company. We have further relied, with your consent, upon the assurances of the management of the Company that they are not aware of any facts that would make the information, representations and projections provided by them inaccurate, incomplete or misleading.

We have not been asked to undertake, and have not undertaken, an independent verification of any information provided to or reviewed by us, nor have we been furnished with any such verification and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not conduct, and we were not asked to conduct, a physical inspection of any of the properties or assets of the Company. At your direction, we did not conduct, nor did we assume any responsibility for conducting, any independent evaluation or appraisal of the assets or the liabilities (contingent, derivative, off-balance sheet, or otherwise) of the Company, nor have we been furnished with any such evaluations or appraisals, nor have we evaluated the solvency or fair value of the Company under any applicable laws.

We also have assumed, with your consent, that the final executed form of the Agreement will not differ in any material respects from the draft reviewed by us and] that the consummation of the Transaction will be effected in accordance with the terms and conditions of the Agreement, without waiver, modification or amendment of any material term, condition or agreement, and that, in the course of obtaining the necessary regulatory or third party consents and approvals (contractual or otherwise) for the Transaction, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on the Company or Parent or the contemplated benefits of the Transaction. We have also assumed that the representations and warranties made by the Company, Parent and Acquisition Sub in the Agreement are and will be true and correct in all respects material to our analysis. We do not express any opinion as to any tax or other consequences that might result from the Transaction, nor does our opinion address any legal, tax, regulatory or accounting matters, as to which we understand that the Company obtained such advice as it deemed necessary from qualified professionals. We are not legal, tax or regulatory advisors and have relied upon without independent verification the assessment of the Company and its legal, tax and regulatory advisors with respect to such matters.

We have not considered the relative merits of the Transaction as compared to any other business plan or opportunity that might be available to the Company or the effect of any other arrangement in which the Company might engage and our opinion does not address the underlying decision by the Company to engage in the Transaction. Our opinion is limited to the fairness as of the date hereof, from a financial point of view, to the holders of the Shares of the Consideration to be received by such holders in the Transaction, and our opinion does not address any other aspect or implication of the Transaction, the Agreement, or any other agreement or understanding entered into in connection with the Transaction or otherwise. We further express no opinion or view as to the fairness of the Transaction to the holders of any other class of securities, creditors or other constituencies of the Company or as to the underlying decision by the Company to engage in the Transaction. We also express no opinion as to the fairness of the amount or nature of the compensation to any of the Company’s officers, directors or employees, or any class of such persons, relative to the Consideration to be received by the holders of the Shares or otherwise.

If the certificate of incorporation contains such a provision, the provisions of this section, including those set forth in subsections (d), (e), and (g) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger, consolidation, conversion, transfer, domestication or continuance for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations or the converting, transferring, domesticating or continuing corporation, and shall include in such notice either a copy of this section (and, if 1 of the constituent corporations or the converting corporation is a nonstock corporation, a copy of § 114 of this title) or information directing the stockholders to a publicly available electronic resource at which this section (and, § 114 of this title, if applicable) may be accessed without subscription or cost. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger, consolidation, conversion, transfer, domestication or continuance, a written demand for appraisal of such stockholder’s shares; provided that a demand may be delivered to the corporation by electronic transmission if directed to an information processing system (if any) expressly designated for that purpose in such notice. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger, consolidation, conversion, transfer, domestication or continuance shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger, consolidation, conversion, transfer, domestication or continuance, the surviving, resulting or converted entity shall notify each stockholder of each constituent or converting, transferring, domesticating or continuing corporation who has complied with this subsection and has not voted in favor of or consented to the merger, consolidation, conversion, transfer, domestication or continuance, and any beneficial owner who has demanded appraisal under paragraph (d)(3) of this section, of the date that the merger, consolidation or conversion has become effective; or

(2) If the merger, consolidation, conversion, transfer, domestication or continuance was approved pursuant to § 228, § 251(h), § 253, or § 267 of this title, then either a constituent, converting, transferring, domesticating or continuing corporation before the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, or the surviving, resulting or converted entity within 10 days after such effective date, shall notify each stockholder of any class or series of stock of such constituent, converting, transferring, domesticating or continuing corporation who is entitled to appraisal rights of the approval of the merger, consolidation, conversion, transfer, domestication or continuance and that appraisal rights are available for any or all shares of such class or series of stock of such constituent, converting, transferring, domesticating or continuing corporation, and shall include in such notice either a copy of this section (and, if 1 of the constituent corporations or the converting, transferring, domesticating or continuing corporation is a nonstock corporation, a copy of § 114 of this

C-2

TABLE OF CONTENTS

title) or information directing the stockholders to a publicly available electronic resource at which this section (and § 114 of this title, if applicable) may be accessed without subscription or cost. Such notice may, and, if given on or after the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, shall, also notify such stockholders of the effective date of the merger, consolidation, conversion, transfer, domestication or continuance. Any stockholder entitled to appraisal rights may, within 20 days after the date of giving such notice or, in the case of a merger approved pursuant to § 251(h) of this title, within the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days after the date of giving such notice, demand in writing from the surviving, resulting or converted entity the appraisal of such holder’s shares; provided that a demand may be delivered to such entity by electronic transmission if directed to an information processing system (if any) expressly designated for that purpose in such notice. Such demand will be sufficient if it reasonably informs such entity of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, either (i) each such constituent corporation or the converting, transferring, domesticating or continuing corporation shall send a second notice before the effective date of the merger, consolidation, conversion, transfer, domestication or continuance notifying each of the holders of any class or series of stock of such constituent, converting, transferring, domesticating or continuing corporation that are entitled to appraisal rights of the effective date of the merger, consolidation, conversion, transfer, domestication or continuance or (ii) the surviving, resulting or converted entity shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice or, in the case of a merger approved pursuant to § 251(h) of this title, later than the later of the consummation of the offer contemplated by § 251(h) of this title and 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection and any beneficial owner who has demanded appraisal under paragraph (d)(3) of this section. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation or entity that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation or the converting, transferring, domesticating or continuing corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

(3) Notwithstanding subsection (a) of this section (but subject to this paragraph (d)(3)), a beneficial owner may, in such person’s name, demand in writing an appraisal of such beneficial owner’s shares in accordance with either paragraph (d)(1) or (2) of this section, as applicable; provided that (i) such beneficial owner continuously owns such shares through the effective date of the merger, consolidation, conversion, transfer, domestication or continuance and otherwise satisfies the requirements applicable to a stockholder under the first sentence of subsection (a) of this section and (ii) the demand made by such beneficial owner reasonably identifies the holder of record of the shares for which the demand is made, is accompanied by documentary evidence of such beneficial owner’s beneficial ownership of stock and a statement that such documentary evidence is a true and correct copy of what it purports to be, and provides an address at which such beneficial owner consents to receive notices given by the surviving, resulting or converted entity hereunder and to be set forth on the verified list required by subsection (f) of this section.

(e) Within 120 days after the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, the surviving, resulting or converted entity, or any person who has complied with subsections (a) and (d) of this section and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, any person entitled to appraisal rights who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such person’s demand for appraisal and to accept the terms offered upon the

merger, consolidation, conversion, transfer, domestication or continuance. Within 120 days after the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, any person who has complied with the requirements of subsections (a) and (d) of this section, upon request given in writing (or by electronic transmission directed to an information processing system (if any) expressly designated for that purpose in the notice of appraisal), shall be entitled to receive from the surviving, resulting or converted entity a statement setting forth the aggregate number of shares not voted in favor of the merger, consolidation, conversion, transfer, domestication or continuance (or, in the case of a merger approved pursuant to § 251(h) of this title, the aggregate number of shares (other than any excluded stock (as defined in § 251(h)(6)d. of this title)) that were the subject of, and were not tendered into, and accepted for purchase or exchange in, the offer referred to in § 251(h)(2) of this title)), and, in either case, with respect to which demands for appraisal have been received and the aggregate number of stockholders or beneficial owners holding or owning such shares (provided that, where a beneficial owner makes a demand pursuant to paragraph (d)(3) of this section, the record holder of such shares shall not be considered a separate stockholder holding such shares for purposes of such aggregate number). Such statement shall be given to the person within 10 days after such person’s request for such a statement is received by the surviving, resulting or converted entity or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section, whichever is later.

(f) Upon the filing of any such petition by any person other than the surviving, resulting or converted entity, service of a copy thereof shall be made upon such entity, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all persons who have demanded appraisal for their shares and with whom agreements as to the value of their shares have not been reached by such entity. If the petition shall be filed by the surviving, resulting or converted entity, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving, resulting or converted entity and to the persons shown on the list at the addresses therein stated. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving, resulting or converted entity.

(g) At the hearing on such petition, the Court shall determine the persons who have complied with this section and who have become entitled to appraisal rights. The Court may require the persons who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any person fails to comply with such direction, the Court may dismiss the proceedings as to such person. If immediately before the merger, consolidation, conversion, transfer, domestication or continuance the shares of the class or series of stock of the constituent, converting, transferring, domesticating or continuing corporation as to which appraisal rights are available were listed on a national securities exchange, the Court shall dismiss the proceedings as to all holders of such shares who are otherwise entitled to appraisal rights unless (1) the total number of shares entitled to appraisal exceeds 1% of the outstanding shares of the class or series eligible for appraisal, (2) the value of the consideration provided in the merger, consolidation, conversion, transfer, domestication or continuance for such total number of shares exceeds $1 million, or (3) the merger was approved pursuant to § 253 or § 267 of this title.

(h) After the Court determines the persons entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger, consolidation, conversion, transfer, domestication or continuance, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, and except as provided in this subsection, interest from the effective date of the merger, consolidation, conversion, transfer, domestication or continuance through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger, consolidation or conversion and the date of payment of the judgment. At any time before the entry of judgment in the proceedings, the surviving, resulting or converted entity may pay to each person entitled to appraisal an amount in cash, in which case interest shall accrue thereafter as provided herein only upon the sum of (1) the difference, if any, between the

C-4

TABLE OF CONTENTS

amount so paid and the fair value of the shares as determined by the Court, and (2) interest theretofore accrued, unless paid at that time. Upon application by the surviving, resulting or converted entity or by any person entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the persons entitled to an appraisal. Any person whose name appears on the list filed by the surviving, resulting or converted entity pursuant to subsection (f) of this section may participate fully in all proceedings until it is finally determined that such person is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving, resulting or converted entity to the persons entitled thereto. Payment shall be so made to each such person upon such terms and conditions as the Court may order. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving, resulting or converted entity be an entity of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a person whose name appears on the list filed by the surviving, resulting or converted entity pursuant to subsection (f) of this section who participated in the proceeding and incurred expenses in connection therewith, the Court may order all or a portion of such expenses, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal not dismissed pursuant to subsection (k) of this section or subject to such an award pursuant to a reservation of jurisdiction under subsection (k) of this section.

(k) Subject to the remainder of this subsection, from and after the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, no person who has demanded appraisal rights with respect to some or all of such person’s shares as provided in subsection (d) of this section shall be entitled to vote such shares for any purpose or to receive payment of dividends or other distributions on such shares (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger, consolidation, conversion, transfer, domestication or continuance). If a person who has made a demand for an appraisal in accordance with this section shall deliver to the surviving, resulting or converted entity a written withdrawal of such person’s demand for an appraisal in respect of some or all of such person’s shares in accordance with subsection (e) of this section, either within 60 days after such effective date or thereafter with the written approval of the corporation, then the right of such person to an appraisal of the shares subject to the withdrawal shall cease. Notwithstanding the foregoing, an appraisal proceeding in the Court of Chancery shall not be dismissed as to any person without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just, including without limitation, a reservation of jurisdiction for any application to the Court made under subsection (j) of this section; provided, however that this provision shall not affect the right of any person who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such person’s demand for appraisal and to accept the terms offered upon the merger, consolidation, conversion, transfer, domestication or continuance within 60 days after the effective date of the merger, consolidation, conversion, transfer, domestication or continuance, as set forth in subsection (e) of this section. If a petition for an appraisal is not filed within the time provided in subsection (e) of this section, the right to appraisal with respect to all shares shall cease.

(l) The shares or other equity interests of the surviving, resulting or converted entity to which the shares of stock subject to appraisal under this section would have otherwise converted but for an appraisal demand made in accordance with this section shall have the status of authorized but not outstanding shares of stock or other equity interests of the surviving, resulting or converted entity, unless and until the person that has demanded appraisal is no longer entitled to appraisal pursuant to this section.
