Insights

Corporate Finance Analyst

Registration documents a reseller overhang but no issuer dilution.

The filing registers 21,010,640 shares for resale by selling holders, including consideration shares issued at the closing of the DTR Acquisition. This is a resale registration; the company states it will not receive proceeds from resale transactions.

Material context to watch in subsequent filings includes the timing and pace of selling‑holder liquidations and any cash exercises of warrants that would generate up to $11,764,680 and $2,500,000, respectively.

Securities & Transactions Attorney

Registration fulfills contractual registration rights tied to acquisitions and warrants.

The Registration Rights Agreement requires the company to register the Consideration Shares and other registrable securities within five business days after the DTR Closing. The prospectus lists customary piggyback and demand registration features and indemnities.

Key legal qualifiers disclosed include the Special Committee review of the DTR Acquisition, a non‑competition agreement with the seller, and that the resale is subject to the selling holders’ discretion and applicable securities laws.

Registration Rights Agreement regulatory

"Under the terms of the Registration Rights Agreement, the Company agreed to prepare and file a registration statement"

A registration rights agreement is a contract that gives investors the option to have their ownership stakes officially registered with the government, making it easier to sell their shares later. This agreement matters because it provides investors with a clearer path to cash out their investments if they choose, offering more liquidity and confidence in their ability to sell their holdings when desired.

Consideration Shares financial

"the Consideration Shares were calculated as 31.5% of the aggregate number of shares"

Up-C Collapse corporate

"On November 3, 2025, the Company completed a transaction to simplify its organizational structure (the "Up-C Collapse")"

DTR Acquisition

On January 11, 2026, the Company entered into the Purchase Agreement with Opco, DTR and Akshay Naheta. Pursuant to the Purchase Agreement, the Company agreed to acquire 100% of the equity interests of DTR (the “DTR Acquisition”). The DTR Acquisition was approved by the Company’s stockholders on April 17, 2026. The DTR Acquisition was completed on April 30, 2026.

-1-

Table of Contents

In connection with the Closing, the Company issued to Akshay Naheta and the other beneficial owners of DTR (collectively, the “DTR Holders”) an aggregate of 11,316,775 shares of Class A Common Stock, calculated as 31.5% of the aggregate number of shares of Class A Common Stock outstanding immediately prior to the Closing (on an as-converted basis, excluding certain warrants), subject to a downward adjustment of 196,532 shares. Up to 725,592 additional shares of Class A Common Stock are issuable as additional Consideration Shares upon the exercise of certain outstanding warrants.

Mr. Naheta, our Chief Executive Officer and a member of our Board of Directors, is a Selling Stockholder and a party to the DTR Acquisition, is a significant existing stockholder of the Company. Mr. Naheta recused himself from the review and approval of the DTR Acquisition, which was negotiated and approved by a special committee of independent and disinterested directors and subsequently approved by the full board of directors. Upon completion of the DTR Acquisition, Mr. Naheta beneficially owned 11,522,681 shares of Class A Common Stock of the Company, approximately 22.3% of the Company’s securities.

Mr. Naheta is not selling shares on behalf of the Company and will determine, in his sole discretion, whether, when and how to sell any shares covered by this prospectus. The Company will not participate in any such sales. We are registering the securities held by Mr. Naheta solely to satisfy contractual registration rights that we have granted to certain of the Selling Stockholders in connection with the DTR Acquisition.

In connection with the DTR Acquisition, the Company entered into certain related agreements, including the Registration Rights Agreement providing for the registration of the resale of the Consideration Shares and certain other securities, as well as voting and support agreements with certain stockholders of the Company. See “The DTR Acquisition” for additional information.

Gyzer Acquisition

In May 2026, the Company acquired all of the issued and outstanding shares of Gyzer Inc. (“Gyzer”). In connection with the acquisition, the Company issued shares of its Class A Common Stock and warrants to purchase its Class A Common Stock (“Gyzer Acquisition Warrants”) to Daniel Ishag, Gyzer’s founder and the Company’s Chief Commercial Officer, as consideration for the transaction. This prospectus relates to the resale of such shares. See “Gyzer Acquisition” for additional information.

Up-C Collapse

On November 3, 2025, the Company completed a transaction to simplify its organizational structure (the “Up-C Collapse”), pursuant to which the Company eliminated its prior Up-C structure by acquiring outstanding equity interests in Bakkt Opco Holdings, LLC (“Opco”) held by non-controlling equity holders of Opco in exchange for shares of the Company’s Class A Common Stock. In connection with the Up-C Collapse, the Company issued shares of Class A Common Stock to such holders as consideration for the acquisition of their equity interests in Opco and entered into, and subsequently amended, agreements relating to its tax receivable and contribution arrangements to reflect the simplified structure. The offer and resale of certain of those shares of Class A Common Stock is being registered pursuant to this registration statement. Following the Up-C Collapse, the Company owns 100% of the equity interests in Opco. See “Up-C Collapse” for additional information. The Securities That May Be Offered

This prospectus relates solely to the resale of shares of Class A Common Stock by the Selling Stockholders and not to any offering of securities by the Company. We are not selling any securities under this prospectus and will not receive any proceeds from the resale of shares by the Selling Stockholders, although we may receive proceeds from the exercise of the warrants and to the extent any such warrants are exercised for cash. We have not entered into any arrangement or understanding with any Selling Stockholder or any other person regarding the distribution of the shares. All proceeds from such resales will be received by the Selling Stockholders for their own accounts.

-2-

Table of Contents

The Selling Stockholders may offer up to 21,010,640 shares of our Class A Common Stock. As at April 30, 2026, there are 47,866,956 shares of Class A Common Stock outstanding. After giving effect to the issuance of the maximum number of shares of Class A Common Stock offered hereunder, 48,578,316 shares of Class A Common Stock would be outstanding.

The Selling Stockholders may resell the shares covered by this prospectus from time to time in ordinary brokerage transactions, block trades, privately negotiated transactions or similar transactions, as described in the section of this prospectus captioned “Plan of Distribution.”

Holders of our Class A Common Stock are entitled to receive dividends declared by our board of directors out of funds legally available for the payment of dividends, subject to rights, if any, of preferred stockholders.

The holders of Class A Common Stock have no preemptive rights.

RISK FACTORS

An investment in our Class A Common Stock involves a high degree of risk. Before you decide whether to purchase our Class A Common Stock in this offering, you should consider the risks described below, together with all of the other information contained or incorporated by reference in the prospectus supplement or appearing or incorporated by reference in this prospectus. You should also consider the risks, uncertainties and assumptions discussed under “Part I—Item 1A—Risk Factors” of our most recent Annual Report on Form 10-K and in “Part II—Item 1A—Risk Factors” of our Quarterly Reports on Form 10-Q filed subsequently to such Form 10-K that are incorporated herein by reference, as may be amended, supplemented or superseded from time to time by other reports we file with the SEC in the future. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also affect our operations.

Risks Related to this Offering

Investors who buy shares at different times will likely pay different prices.

The Selling Stockholders may resell all, some, or none of their shares of Class A Common Stock at any time or from time to time in their discretion and at different prices. As a result, investors who purchase shares from the Selling Stockholders in this offering at different times will likely pay different prices for those shares, and so may experience different levels of dilution, and in some cases substantial dilution, and different outcomes in their investment results. Investors may experience a decline in the value of the shares they purchase from the Selling Stockholders in this offering as a result of future sales of our Class A Common Stock by us in future offerings or by the Selling Stockholders, including at prices lower than the prices such investors paid for their shares in this offering.

Sales of a substantial number of our shares of Class A Common Stock, including by the Selling Stockholders, could cause the market price of our Class A Common Stock to decline.

The Selling Stockholders may resell, under this prospectus, up to 21,010,640 shares of our Class A Common Stock. If all of these shares were issued and outstanding as of April 30, 2026, they would represent approximately 43.9% of the total number of our outstanding voting securities. This prospectus relates solely to the resale of shares by the Selling Stockholders, and we are not selling any securities under this prospectus and will not receive any proceeds from such resales.

The Selling Stockholders may sell all, some or none of their shares at any time and from time to time in their sole discretion, and we have no control over the timing or amount of such sales and will not participate in any resale transactions. Sales of a substantial number of shares of our Class A Common Stock in the public market by the Selling Stockholders and/or by our other existing stockholders, or the perception that such sales might occur, could depress the market price of our Class A Common Stock and impair our ability to raise capital through the sale of additional equity securities.

This risk may be heightened because our Chief Executive Officer is a Selling Stockholder and holds a significant portion of our outstanding Class A Common Stock. Sales by Mr. Naheta, or the perception that such sales may occur, could create a public market “overhang” and adversely affect the market price of our Class A Common Stock. In addition, because Mr. Naheta has access to material non-public information, his ability to sell shares will be subject to blackout periods or other restrictions, which could result in the timing of sales being concentrated in particular periods.

Risks Related to the Ownership of Our Class A Common Stock

Future sales of our Class A Common Stock could lower our stock price and dilute existing stockholders.

We may, in the future, sell additional shares of Class A Common Stock in subsequent public or private offerings. We cannot predict the size or terms of future issuances of our Class A Common Stock or the effect, if any, that future sales and issuances of shares of our Class A Common Stock will have on the market price of our Class A Common Stock. Sales of substantial amounts of our Class A Common Stock, or the perception that such sales could occur, may adversely affect prevailing market prices for our Class A Common Stock. In addition, these sales may be dilutive to existing stockholders.

-4-

Table of Contents

We may fail to meet our publicly announced guidance or other expectations about our business, which would cause our stock price to decline.

We may provide guidance regarding our expected financial and business performance, such as projections regarding sales and production, as well as anticipated future revenue, gross margins, profitability, and cash flows. Correctly identifying key factors affecting business conditions and predicting future events is inherently an uncertain process and our guidance may not ultimately be accurate. Our guidance is based on certain assumptions such as those relating to anticipated production and sales volumes and average sales prices, supplier and commodity costs, and planned cost reductions. If our guidance is not accurate or varies from actual results due to our inability to meet our assumptions or the impact on our financial performance that could occur as a result of various risks and uncertainties, the market value of our Class A Common Stock could decline significantly.

We do not intend to pay dividends for the foreseeable future.

We have never declared nor paid cash dividends on our capital stock. We currently intend to retain any future earnings to finance the operation and expansion of our business, and we do not expect to declare or pay any dividends in the foreseeable future. Consequently, stockholders must rely on sales of their Class A Common Stock after price appreciation, which may never occur, as the only way to realize any future gains on their investment.

FORWARD-LOOKING STATEMENTS

This prospectus, any accompanying prospectus supplement and the documents incorporated by reference herein and therein contain forward-looking statements within the meaning of the federal securities laws, which statements involve substantial risks and uncertainties. Forward-looking statements generally relate to future events or our future financial or operating performance. You can identify forward-looking statements because they contain words such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intends,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “will,” “would,” the negative of such terms, and other similar expressions that are intended to identify forward-looking statements. These forward-looking statements are based on management’s current expectations, assumptions, hopes, beliefs, intentions and strategies regarding future events and are based on currently available information as to the outcome and timing of future events. We caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond our control, incident to our business. Forward-looking statements included or incorporated by reference into this prospectus may include, for example, statements about:

• expectations regarding our strategic transformation and completion thereof;

• future financial and operational performance;

• industry growth in stablecoins, tokenization and digital assets;

• regulatory developments.

These forward-looking statements are based on information available as of the date they were made and reflect management’s expectations, forecasts and assumptions as of such date, and involve a number of judgments, known and/or unknown risks and uncertainties. Accordingly, forward-looking statements should not be relied upon as representing our views as of any subsequent date. We do not undertake any obligation to update any forward-looking statement to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable law.

You should not place undue reliance on these forward-looking statements. Should one or more of a number of known and unknown risks and uncertainties materialize, or should any of our assumptions prove incorrect, our actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include, but are not limited to:

• our ability to grow and manage growth profitably;

• whether we will be able to successfully integrate our operations with those of DTR, including its infrastructure, and achieve the expected benefits therefrom;

• the regulatory environment for digital assets and digital stablecoin payments;

• changes in our business strategy;

• our adoption of our updated investment policy and related treasury strategy, including our ability to successfully consummate acquisitions, integrate or manage investments in potential acquisition targets and investees;

• our ability to execute and consummate a definitive agreement with Zoth and its expected benefit;

• the price of digital assets, including Bitcoin;

• risks associated with owning digital assets, including Bitcoin, including price volatility, limited liquidity and trading volumes, relative anonymity, potential widespread susceptibility to market abuse and manipulation, compliance and internal control failures at exchanges and other risks inherent in its entirely electronic, virtual-form and decentralized network;

• the fluctuation of our operating results, including because we may be required to account for our digital assets at fair value;

• our ability to time the price of our purchase of digital assets pursuant to our strategy;

-6-

Table of Contents

• the impact of the market value of digital assets on our ability to satisfy our financial obligations, including any debt financings;

• unrealized fair value gains on our digital asset holdings subjecting us to the corporate alternative minimum tax;

• legal, commercial, regulatory and technical uncertainty regarding digital assets and enhanced regulatory oversight of companies holding digital assets including the possibility that regulators reclassify any digital assets we hold, including Bitcoin, as a security causing us to be in violation of securities laws and be classified as an “investment company” under the Investment Company Act of 1940;

• competition by other Bitcoin treasury companies and the availability of spot-traded products for Bitcoin;

DESCRIPTION OF CAPITAL STOCK

The description of our capital stock is incorporated by reference to Exhibit 4.9 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, filed with the SEC on March 19, 2026.

THE DTR ACQUISITION

On January 11, 2026, Opco, the Company, DTR, and Akshay Naheta entered into the Purchase Agreement. Pursuant to the terms and subject to the conditions set forth in the Purchase Agreement, the Company completed the acquisition of all of the outstanding equity interests of DTR (the “DTR Acquisition”) on April 30, 2026 (the “Closing”) by issuing to the DTR Holders an aggregate of 11,316,775 shares of Class A Common Stock (the “Consideration Shares”). The Consideration Shares were calculated as (A) 31.5% of (i) the aggregate number of shares of Class A Common Stock issued and outstanding immediately prior to the Closing plus (ii) the aggregate number of shares of the Company’s capital stock issuable upon full exercise or conversion of any options or other convertible derivative securities outstanding immediately prior to the Closing, on an as-converted basis, excluding any outstanding warrants to purchase shares of Class A Common Stock, less (B) an adjustment amount of 196,532 shares (the “Adjustment Amount”).

The number of Consideration Shares was reduced by the Adjustment Amount, which reflects (x) the aggregate amount of certain shareholder loans extended to DTR by the Seller or his affiliates outstanding immediately prior to the Closing and (y) transaction expenses incurred by DTR or Mr. Naheta in excess of $1.5 million, divided by (z) the volume-weighted average trading price of the Company’s Class A Common Stock over

the 20 consecutive trading day period ending on and including the day immediately prior to the Closing, or $8.65. In addition, following the Closing, to the extent the Company issues shares of Class A Common Stock upon the exercise or conversion of warrants outstanding as of the date of the Purchase Agreement, the Consideration Shares will be increased by a number of shares equal to 31.5% of the number of shares issued upon such exercise or conversion, which could result in the issuance of up to an additional 725,592 shares of Class A Common Stock.

A Special Committee of the Board, composed entirely of independent and disinterested directors (the “Special Committee”), was formed and granted full authority to review, negotiate, and approve the terms of the DTR Acquisition on behalf of the Company. After evaluating the DTR Acquisition, the Special Committee unanimously determined that the DTR Acquisition was fair to, and in the best interests of, the Company and its stockholders (excluding Mr. Naheta and his affiliates), approved the DTR Acquisition, and recommended that the full Board (excluding Mr. Naheta from such consideration) approve the DTR Acquisition.

Following the Special Committee’s approval, the Board (excluding Mr. Naheta from such consideration) approved the DTR Acquisition and determined to submit the DTR Acquisition to the Company’s stockholders for approval. Mr. Naheta is a member of the Board and recused himself from consideration and deliberation with respect to the DTR Acquisition and abstained from the vote.

The Company’s stockholders approved the DTR Acquisition on April 17, 2026. The DTR Acquisition was completed on April 30, 2026, with the Company acquiring all of the outstanding equity interests of DTR.

In connection with the Purchase Agreement: (i) each current DTR Holder entered into a joinder agreement pursuant to which such holder agreed to be bound by the obligations of the Seller under the Purchase Agreement, (ii) the Seller entered into a non-competition agreement (the “Non-Competition Agreement”) with the Company, (iii) each current DTR Holder, the Company, Mr. Naheta and ICE entered into the Registration Rights Agreement and (iv) the Company and certain stockholders entered into a voting and support agreement (the “Voting and Support Agreement”).

Non-Competition Agreement

Pursuant to the Non-Competition Agreement, Mr. Naheta has agreed, effective at the Closing, to not, without the prior written consent of the Company, compete with the business, activities, products or services conducted, authorized, offered, or provided by the Company or any of its subsidiaries in the United States, or any other jurisdiction where the Company conducts business as of the Closing during a period beginning on the date of the Closing and ending on the first anniversary of the Closing (the “Restricted Period”), or, upon exercise by the Company, in the Company’s sole discretion, a later date that is on or prior to the second anniversary of the Closing (such period, the “Extension Period”). If (i) Mr. Naheta’s employment is terminated with the Company or any subsidiary or affiliate thereof, regardless of whether the Company or Mr. Naheta initiated the termination of employment, and (ii) the Company has elected to extend the Restricted Period into the Extension Period, then after the first anniversary of the Closing, the Company shall pay to Mr. Naheta monthly compensation for each month of the Extension Period in an amount equal to 100% of Mr. Naheta’s average monthly base salary from the Company during the twelve months immediately preceding such termination.

Amended and Restated Registration Rights Agreement

The Registration Rights Agreement, which became effective at the Closing, amends and restates that certain Registration Rights Agreement, dated as of October 15, 2021, pursuant to which the Company granted ICE and the other holders party thereto certain registration rights with respect to certain securities of the Company. Under the terms of the Registration Rights Agreement, the Company agreed, among other things, to register for resale (a) any Class A Common Stock currently owned by ICE or that may be issued upon exercise of any warrants currently owned by ICE, (b) the Consideration Shares, and (c) any other equity securities of the Company issued or issuable to any stockholder with respect to any such share of Class A Common Stock referred to in clauses (a) and (b) by way of a stock dividend or stock split or in connection with a combination of shares, recapitalization, merger, consolidation or reorganization (collectively, the “Registrable Securities”). Under the terms of the Registration Rights Agreement, the Company has agreed to prepare and file a registration statement with the SEC to register for resale the Registrable Securities within five business days after the date of the Closing. The Company has agreed to

be responsible for all fees and expenses incurred in connection with such registration. Furthermore, under the Registration Rights Agreement, the holders of the Registrable Securities have certain customary underwritten offering demand rights and piggyback registration rights. The Company has granted certain customary piggyback registration rights and indemnification rights in connection with such registration of Registrable Securities.

Voting and Support Agreement

Pursuant to the Voting and Support Agreement, the Voting and Support Parties agreed to vote their shares of the Company’s Class A Common Stock (including those owned beneficially) in favor of the DTR Acquisition. The Voting and Support Agreement automatically terminated upon the Closing. At the time of execution, the Voting and Support Parties together beneficially owned approximately 36.1% of the outstanding shares of Class A Common Stock.

The foregoing descriptions of the Purchase Agreement, the Non-Competition Agreement, the Registration Rights Agreement and the Voting and Support Agreement are not complete and are qualified in their entirety by reference to the full text of such agreements, which are filed as Exhibits 10.1, 10.2, 10.3 and 10.4, respectively, hereto and are incorporated herein by reference.

GYZER ACQUISITION

In May 2026, the Company completed the acquisition of all of the issued and outstanding equity interests of Gyzer Inc. (“Gyzer”), a digital asset payments business. In connection with the acquisition, the Company issued 94,595 shares of its Class A Common Stock and warrants to purchase 250,000 shares of its Class A Common Stock to Daniel Ishag, the sole stockholder of Gyzer and the Company’s Chief Commercial Officer, as consideration for the transaction. This prospectus relates to the resale of such shares by the applicable Selling Stockholder, including any shares received by the applicable Selling Stockholder upon the exercise of the Gyzer Acquisition Warrants.

UP-C COLLAPSE

On November 3, 2025, the Company completed a transaction to simplify its organizational structure (the “Up-C Collapse”), pursuant to which the Company eliminated its prior umbrella partnership-C corporation (“Up-C”) structure. Prior to the Up-C Collapse, the Company operated through Bakkt Opco Holdings, LLC (“Opco”), in which certain non-controlling equity holders held interests.

In connection with the Up-C Collapse, the Company acquired the outstanding equity interests in Opco held by such non-controlling equity holders in exchange for shares of the Company’s Class A Common Stock. As a result of the Up-C Collapse, such holders became stockholders of the Company, and the Company directly or indirectly acquired 100% of the equity interests in Opco.

In connection with the Up-C Collapse, the Company issued shares of Class A common stock to the former holders of Opco equity interests as consideration for the acquisition of their equity interests in Opco. Such shares were issued in reliance on the exemptions from registration under the Securities Act. This prospectus relates to the resale of certain of such shares by the applicable Selling Stockholders.

In connection with the Up-C Collapse, the Company, ICE and Akshay Naheta entered into (i) Amendment No. 1 to the Tax Receivable Agreement, dated as of October 16, 2025, which amended the Tax Receivable Agreement, dated as of October 15, 2021, (ii) the Contribution Agreement, dated as of October 16, 2025 (the “Contribution Agreement”), and (iii) the Contribution Agreement Amendment, dated as of November 3, 2025, which amended the Contribution Agreement in connection with the consummation of the Up-C Collapse. These agreements reflect the elimination of the Up-C structure and address the parties’ respective rights and obligations following the Up-C Collapse, including with respect to tax attributes and related payments. Following the Up-C Collapse, the Company owns 100% of the equity interests in Opco and no longer has non-controlling equity holders at the Opco level.

The Company has not provided, and will not provide, any financing or other assistance to the Selling Stockholders in connection with the resale of the shares. The Selling Stockholders will not pay any of the costs, expenses and fees in connection with the registration of the shares covered by this prospectus, but they will pay any and all underwriting discounts, selling commissions and similar charges attributable to sales of the shares. All proceeds from the resale of shares will be received by the Selling Stockholders for their own accounts. The Selling Stockholders may sell some or all of the shares of Class A Common Stock covered by this prospectus from time to time or may decide not to sell any of the shares of Common Stock covered by this prospectus. As used in this prospectus, “Selling Stockholders” includes any transferees of Registrable Securities who become parties to the Registration Rights Agreement in accordance with its terms, including by executing a joinder thereto. The Selling Stockholders will act independently of us in making decisions with respect to the timing, manner and size of each sale. We have no control over, and will not participate in, any such sales. Such sales are not being made pursuant to any underwriting or other coordinated distribution arrangement on behalf of the Company, and will be made in ordinary brokerage transactions, block trades, privately negotiated transactions or similar transactions. Such sales may be made on one or more exchanges or in the over-the-counter market at prices and under terms then prevailing or at prices related to the then-current market price or in negotiated transactions. The Selling Stockholders may dispose of their shares by one or more of, or a combination of, the following methods:

• purchases by a broker-dealer as principal and resale by such broker-dealer for its own account pursuant to this prospectus;

• ordinary brokerage transactions and transactions in which the broker solicits purchasers;

• block trades in which the broker-dealer so engaged will attempt to sell the shares as agent but may position and resell a portion of the block as principal to facilitate the transaction;

• through trading plans entered into by Selling Stockholders pursuant to Rule 10b5-1 under the Exchange Act, that are in place at the time of an offering pursuant to this prospectus and any applicable prospectus supplement hereto that provide for periodic sales of their securities on the basis of parameters described in such trading plans;

• in privately negotiated transactions; or

• through a combination of any of the above methods of sale.

In addition, any shares that qualify for sale pursuant to Rule 144 may be sold under Rule 144 rather than pursuant to this prospectus.

The Selling Stockholders do not currently have any agreements, arrangements or understandings with any person to distribute the shares. The Company has not participated in, and will not participate in, any such arrangements or in the resale of the shares. The Company has not been involved in identifying or engaging any such persons.

In effecting sales, broker-dealers or agents engaged by the Selling Stockholders may arrange for other broker-dealers to participate. Broker-dealers or agents may receive commissions, discounts or concessions from the Selling Stockholders in amounts to be negotiated immediately prior to the sale.

In offering the shares covered by this prospectus, the Selling Stockholders and any broker-dealers who execute sales for the selling stockholders may be deemed to be or are “underwriters” within the meaning of the Securities Act in connection with such sales. Any profits realized by the Selling Stockholders and the compensation of any broker-dealer may be deemed to be underwriting commissions, discounts or concessions.

We have advised the Selling Stockholders that the anti-manipulation rules of Regulation M under the Exchange Act may apply to sales of shares in the market and to the activities of the Selling Stockholders and their affiliates. In addition, we will make copies of this prospectus available to the Selling Stockholders for the purpose of satisfying the prospectus delivery requirements of the Securities Act.

Item 15. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law (“DGCL”) authorizes a corporation’s board of directors to grant, and authorizes a court to award, indemnity to officers, directors and other corporate agents.

Our Certificate of Incorporation contains provisions that limit the liability of our directors for monetary damages to the fullest extent permitted by the DGCL. Consequently, our directors will not be personally liable to us or our stockholders for monetary damages for any breach of fiduciary duties as directors, except liability for the following:

• any breach of their duty of loyalty to our company or our stockholders;

• any act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;

• unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or

• any transaction from which they derived an improper personal benefit.

Any amendment, repeal or elimination of these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim that occurred or arose prior to that amendment, repeal or elimination. If the DGCL is amended to provide for further limitations on the personal liability of directors of corporations, then the personal liability of our directors will be further limited to the greatest extent permitted by the DGCL.

In addition, our By-Laws provide that we will indemnify our directors and officers, and may indemnify our employees, agents and any other persons, to the fullest extent permitted by the DGCL. Our By-Laws also provide that we must advance expenses incurred by or on behalf of a director or officer in advance of the final disposition of any action or proceeding, subject to limited exceptions.

II-1

Table of Contents

Further, we have entered into or will enter into indemnification agreements with each of our directors and executive officers that may be broader than the specific indemnification provisions contained in the DGCL. These indemnification agreements require us, among other things, to indemnify our directors and executive officers against liabilities that may arise by reason of their status or service. These indemnification agreements also require us to advance all expenses reasonably and actually incurred by the directors and executive officers in investigating or defending any such action, suit or proceeding. We believe that these agreements are necessary to attract and retain qualified individuals to serve as directors and executive officers.

The limitation of liability and indemnification provisions included in our Certificate of Incorporation, By-Laws and the indemnification agreements that we have entered into or will enter into with our directors and executive officers may discourage stockholders from bringing a lawsuit against our directors and executive officers for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against our directors and executive officers, even though an action, if successful, might benefit us and other stockholders. Further, a stockholder’s investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and executive officers as required by these indemnification provisions.

We have obtained insurance policies under which, subject to the limitations of the policies, coverage is provided to our directors and executive officers against loss arising from claims made by reason of breach of fiduciary duty or other wrongful acts as a director or executive officer, including claims relating to public securities matters, and to us with respect to payments that may be made by us to these directors and executive officers pursuant to our indemnification obligations or otherwise as a matter of law.

Certain of our non-employee directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities incurred in their capacity as members of the Board.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers, or persons controlling our company pursuant to the foregoing provisions, we have been informed that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

Item 17. Undertakings

(a) The undersigned registrant hereby undertakes:

(1) to file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

II-4

Table of Contents

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended, or the Exchange Act, that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) that, for the purpose of determining liability under the Securities Act to any purchaser:

(i) each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) that, for the purpose of determining liability of a registrant under the Securities Act to any purchaser in the initial distribution of the securities, the undersigned registrant undertakes that in a primary offering of securities of such undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

II-5

Table of Contents

(iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(6) that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(7) to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Trust Indenture Act.

(b) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
