5 terms

shelf registration regulatory

"part of an automatic shelf registration statement on Form S-3"

Shelf registration is when a company gets permission ahead of time to sell new stocks or bonds over a period of time instead of all at once. It matters to investors because it lets a company raise money quickly when needed, but it can also change the value of existing shares if many new ones are sold.

selling stockholders market

"selling stockholders identified in this prospectus, Imola JV Holdings L.P. and Ingram Holdco, LLC"

Selling stockholders are existing owners of a company's shares who are offering some or all of their holdings for sale, often as part of a public offering or secondary transaction. For investors this matters because such sales increase the number of shares available to buy, can signal how confident current owners are about future prospects, and may put short-term pressure on the stock price similar to more tickets being released for a popular event.

Margin Loan financial

"Margin Loan dated as of August 27, 2025, by and among Ingram Holdco LLC"

A margin loan is money you borrow from a brokerage using the stocks or funds you already own as collateral, similar to taking a loan against items in a pawnshop. It lets an investor buy more securities than cash alone would allow, which can amplify gains but also magnify losses, incur interest charges and trigger forced selling if the collateral value falls below required levels—risks investors must manage carefully.

piggyback registration rights legal

"the selling stockholders will be entitled to certain “piggyback” registration rights"

A contractual right that lets existing shareholders join a company’s planned public sale of stock so they can sell their own shares at the same time under the same paperwork. It matters to investors because it gives insiders and early holders an easier, often faster way to convert shares to cash, while also potentially increasing the number of shares offered and affecting the share price — like catching a scheduled bus instead of hiring a private ride to get where you need to go.

Investor Rights Agreement legal

"Investor Rights Agreement we entered into in connection with the IPO"

A legally binding contract between a company and its investors that spells out investors’ core protections and privileges—such as voting rights, how and when shares can be sold, information access, and steps for resolving disputes. Think of it like a rulebook or homeowner association agreement for ownership: it clarifies who gets a say, how value can be realized, and what protections exist if things go wrong, making investment risks and expectations clearer for shareholders.

Any statement so modified or superseded will not be deemed, except as so modified or superseded, to constitute a part of this prospectus.

Neither we nor the selling stockholders have authorized anyone to provide you with different information. The Company and the selling stockholders take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give you. The information included in or incorporated by reference in this prospectus is accurate only as of the date of the applicable document, regardless of the time of delivery of this prospectus and the applicable prospectus supplement or any free writing prospectus, as the case may be, or any sales of shares of our Common Stock.

Forward-looking statements may contain words such as “believes,” “expects,” “may,” “will,” “should,” “seeks,” “intends,” “plans,” “estimates,” or “anticipates,” or similar expressions which concern our strategy, plans, projections or intentions, but such words are not the exclusive means of identifying forward-looking statements in this prospectus.

INDUSTRY AND MARKET DATA

References included or incorporated by reference herein to our being a leader in a market or product category refers to our belief that we have a leading market share position in each specified market, unless the context otherwise requires. In addition, market share data is subject to change and cannot always be verified with certainty due to limits on the availability and reliability of raw data, the voluntary nature of the data gathering process and other limitations and uncertainties inherent in any statistical survey of market shares. While we believe such information is reliable, we have not independently verified any third-party information. While we believe our internal company research, surveys and estimates are reliable, such research, surveys and estimates have not been verified by an independent source. In addition, assumptions and estimates of our and our industries’ future performance are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in “Risk Factors” in this prospectus and the risk factors and other information contained in any applicable prospectus supplement and in our filings with the SEC that are incorporated by reference into this prospectus. These and other factors could cause our future performance to differ materially from our assumptions and estimates. See “Cautionary Note Regarding Forward-Looking Statements.”

This prospectus also contains forward-looking statements that involve risks and uncertainties. See “Cautionary Note Regarding Forward-Looking Statements.” The Company’s actual results could differ materially and adversely from those anticipated in these forward-looking statements as a result of certain factors.

DIVIDEND POLICY

On April 30, 2026, the Company announced that the board of directors had declared a cash dividend on our Common Stock of $0.084 per share. The dividend is payable on May 26, 2026, to stockholders of record as of May 12, 2026. We pay, and intend to continue to pay, quarterly dividends subject to capital availability and periodic determinations made by our board of directors that cash dividends are in the best interests of our stockholders. The declaration, amount and payment of any future dividends on our Common Stock will be, subject to compliance with applicable law, at the sole discretion of our board of directors. Our board of directors may take into account, among other things, general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual and tax implications on the payment of dividends by us to our stockholders or by our subsidiaries to us, including restrictions under our Credit Facilities, the Indenture governing the 2029 Notes and other indebtedness or preferred securities we may incur or issue and such other factors as our board of directors may deem relevant. If we elect to pay such dividends in the future, we may reduce or discontinue entirely the payment of such dividends at any time.

Ingram Micro Holding Corporation is a holding company with no material assets other than indirect ownership of the stock of Ingram Micro Inc., and its operations are conducted through its wholly owned subsidiaries. Our operating subsidiaries are currently subject to certain restrictions and covenants under the Credit Agreements and the Indenture. Our ability to pay cash dividends will depend on the payment of distributions by our current and future subsidiaries, including Ingram Micro Inc., and such distributions may be restricted as a result of contractual agreements, including any future agreements governing their indebtedness. These restrictions and covenants may restrict the ability of those entities to make distributions to Ingram Micro Holding Corporation. See the sections entitled Item 1A. “Risk Factors” and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2025 Form 10-K, as amended or supplemented in our subsequently filed Quarterly Reports on Form 10-Q, which is incorporated by reference herein. Any additional financing arrangement we enter into in the future may include restrictive covenants that limit our subsidiaries’ ability to pay dividends to us. In addition, Delaware law may impose requirements that may restrict our ability to pay dividends to holders of our Common Stock.

14

and restated certificate of incorporation and the Investor Rights Agreement. Pursuant to our amended and restated certificate of incorporation and the Investor Rights Agreement, Platinum retains the right to nominate for election to our board of directors a majority of our directors for so long as it beneficially owns at least 50% of the voting power of all shares of our outstanding stock entitled to vote generally in the election of our directors. See the section entitled “Certain Relationships and Related Person Transactions” in our 2026 Proxy, which is incorporated herein by reference, and “Description of Capital Stock” included in this prospectus.

15

DESCRIPTION OF CAPITAL STOCK

The following summary describes our capital stock and our amended and restated certificate of incorporation, amended and restated bylaws and Investor Rights Agreement to which we and Platinum are party. Because the following is only a summary, it does not contain all of the information that may be important to you. For a complete description, you should refer to our amended and restated certificate of incorporation, amended and restated bylaws and the Investor Rights Agreement, copies of which are incorporated by reference as exhibits to the registration statement of which this prospectus is part, and to the applicable provisions of the DGCL.

Authorized Capital Stock

Our purpose is to engage in any lawful act or activity for which corporations may now or hereafter be organized under the DGCL. Our authorized capital stock consists of 2,000,000,000 shares of Common Stock, par value $0.01 per share, and 100,000,000 shares of undesignated Preferred Stock, par value $0.01 per share.

Common Stock

Voting Rights

Holders of our Common Stock are entitled to one vote for each share held on all matters submitted to a vote of stockholders and do not have cumulative voting rights. An election of directors by our stockholders shall be determined by a plurality of the votes cast by the stockholders entitled to vote on the election.

Dividend Rights

Holders of our Common Stock are entitled to receive proportionately any dividends as may be declared by our board of directors, subject to any preferential dividend rights of any series of Preferred Stock that we may designate and issue in the future.

Liquidation Rights

In the event of our liquidation, dissolution or winding-up, the holders of Common Stock are entitled to receive proportionately our net assets available for distribution to stockholders after the payment in full of all debts and other liabilities and subject to the prior rights of any outstanding Preferred Stock.

Rights and Preferences

Holders of Common Stock have no preemptive, subscription, redemption or conversion rights. There are no sinking funds provisions applicable to our Common Stock. The rights, preferences and privileges of holders of Common Stock are subject to and may be adversely affected by the rights of the holders of shares of any series of Preferred Stock that we may designate and issue in the future.

Fully Paid and Nonassessable

All of our outstanding shares of Common Stock are fully paid and nonassessable.

Preferred Stock

We do not currently have any Preferred Stock outstanding. However, our amended and restated certificate of incorporation authorizes our board of directors to establish one or more series of Preferred Stock (including convertible Preferred Stock). Unless required by law or by the NYSE, the authorized shares of Preferred Stock are available for issuance without further action by you. Our board of directors will be able to determine, with respect to any series of Preferred Stock, the terms and rights of that series, including:

•the designation of the series;

16

•the number of shares of the series, which our board of directors may, except where otherwise provided in the Preferred Stock designation, increase (but not above the total number of authorized shares of the class) or decrease (but not below the number of shares then-outstanding);

•whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series;

•the dates at which dividends, if any, will be payable;

•the redemption rights and price or prices, if any, for shares of the series;

•the terms and amounts of any sinking funds provided for the purchase or redemption of shares of the series;

•the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Company;

•whether the shares of the series will be convertible into shares of any other class or series, or any other security, of the Company or any other corporation and, if so, the specification of the other class or series or other security, the conversion price or prices or rate or rates, any rate adjustments, the date or dates as of which the shares will be convertible and all other terms and conditions upon which the conversion may be made;

•restrictions on the issuance of shares of the same series or of any other class or series; and

•the voting rights, if any, of the holders of the series.

We are able to issue a series of Preferred Stock that could, depending on the terms of the series, impede or discourage an acquisition attempt or other transaction that some, or a majority, of the holders of our Common Stock might believe to be in their best interests or in which the holders of our Common Stock might receive a premium for their Common Stock over the market price of the Common Stock. In addition, the issuance of Preferred Stock may adversely affect the holders of our Common Stock by restricting dividends on the Common Stock, diluting the voting power of the Common Stock or subordinating the liquidation rights of the Common Stock. As a result of these or other factors, the issuance of Preferred Stock may have an adverse impact on the market price of our Common Stock.

Dividends

Declaration and payment of any dividend is subject to the discretion of our board of directors. The time and amount of dividends depends upon, among other things, general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual and tax implications on the payment of dividends by us to our stockholders or by our subsidiaries to us, including restrictions and subject to the covenants under our Credit Facilities, the Indenture and any other future indebtedness or preferred securities we may incur or issue, and such other factors as our board of directors may deem relevant. Our ability to pay dividends is limited by covenants in our existing indebtedness and may be limited by the agreements governing other indebtedness that we or our subsidiaries incur in the future. See “Dividend Policy” in this prospectus and Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2025 Form 10-K and 2026 Q1 10-Q which are incorporated by reference herein. In addition, because we are a holding company and have no direct operations, we are only able to pay dividends from funds we receive from our subsidiaries.

Nomination Rights of Platinum

Our amended and restated certificate of incorporation and the Investor Rights Agreement grant the selling stockholders the right to nominate for election to our board of directors no fewer than that number of directors that would constitute: (i) a majority of the total number of directors so long as Platinum collectively beneficially own at least 50% of the then-outstanding capital stock of the Company; (ii) 40% of the total number of directors so long as Platinum collectively beneficially own at least 40% but less than 50% of the then-outstanding capital stock of the Company; (iii) 30% of the total number of directors so long as Platinum collectively beneficially own at least 30%

17

but less than 40% of the then-outstanding capital stock of the Company; (iv) 20% of the total number of directors so long as Platinum collectively beneficially own at least 20% but less than 30% of the then-outstanding capital stock of the Company; and (v) 10% of the total number of directors so long as Platinum collectively beneficially own at least 5% but less than 20% of the then-outstanding capital stock of the Company. For purposes of calculating the number of directors that the selling stockholders will be entitled to nominate pursuant to the formula outlined above, any fractional amounts shall automatically be rounded up to the nearest whole number. Unless otherwise agreed by the selling stockholders, for so long as Platinum retains the right to nominate a person to our board of directors, each committee of the board of directors will include at least one of the director candidates designated by Platinum, except to the extent such membership would violate applicable securities laws or stock exchange or stock market rules or where the sole purpose of such committee is to address actual or potential conflicts of interest between us and Platinum.

Registration Rights

The following description of the terms of the Investor Rights Agreement is intended as a summary only and is qualified in its entirety by reference to the Investor Rights Agreement filed as an exhibit to the registration statement of which this prospectus is a part.

Demand and Short-Form Registration Rights

The selling stockholders may request that we register their registrable securities on one or more occasions in the future, which registrations may be “shelf registrations.”

Piggyback Registration Rights

At any time that we propose to register any of our securities under the Securities Act (other than a registration relating to employee benefit plans, or solely relating to shares to be sold under Rule 145 or a similar provision under the Securities Act), the selling stockholders will be entitled to certain “piggyback” registration rights allowing them to include their registrable securities in such registration.

Expenses of Registration, Restriction and Indemnification

We will pay all registration expenses, including the legal fees of counsel selected by Platinum, under the Investor Rights Agreement. The demand and piggyback registration rights are subject to customary restrictions such as limitations on the number of shares to be included in the underwritten offering imposed by the managing underwriter. The Investor Rights Agreement also contains customary indemnification and contribution provisions.

Anti-Takeover Effects of Our Amended and Restated Certificate of Incorporation and Bylaws and Provisions of Delaware Law

General

Our amended and restated certificate of incorporation, amended and restated bylaws and the DGCL, which are summarized in the following paragraphs, contain provisions that are intended to enhance the likelihood of continuity and stability in the composition of our board of directors. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control and enhance the ability of our board of directors to maximize stockholder value in connection with any unsolicited offer to acquire us. However, these provisions may have an anti-takeover effect and may delay, deter or prevent a merger or acquisition of the Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider is in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of Common Stock held by stockholders.

Classified Board

Our amended and restated certificate of incorporation provides that our board of directors is divided into three classes of directors, with the classes to be as nearly equal in number as possible and with the directors serving three-year terms. As a result, approximately one-third of our board of directors are elected each year. The classification of

18

directors has the effect of making it more difficult for stockholders to change the composition of our board of directors. Our amended and restated certificate of incorporation and amended and restated bylaws provide that the number of directors is fixed from time to time exclusively pursuant to a resolution adopted by the board of directors, provided that, in the event that the number of directors nominated by the selling stockholders is less than the number that the selling stockholders are entitled to nominate under our amended and restated certificate of incorporation or the Investor Rights Agreement and there are no vacancies on our board of directors, then, upon our receipt of a written request of Platinum, the size of our board shall be increased automatically such that Platinum shall have the right, at any time, to nominate any such additional nominees under our amended and restated certificate of incorporation.

No Cumulative Voting

Under Delaware law, the right to vote cumulatively does not exist unless the certificate of incorporation specifically authorizes cumulative voting. Our amended and restated certificate of incorporation does not authorize cumulative voting. Therefore, stockholders holding a majority in voting power of the shares of our stock entitled to vote generally in the election of directors will be able to elect all of our directors.

Removal of Directors; Vacancies

Under the DGCL, unless otherwise provided in our certificate of incorporation, directors serving on a classified board may be removed by the stockholders only for cause. Our amended and restated certificate of incorporation provides that directors may be removed with or without cause upon the affirmative vote of a majority in voting power of all outstanding shares of stock entitled to vote thereon, voting together as a single class; provided, however, that from and after the time Platinum and its affiliates cease to beneficially own, in the aggregate, at least a majority of the voting power of our outstanding Common Stock, directors may only be removed for cause, and only by the affirmative vote of holders of at least 66 and 2/3% in voting power of all the then-outstanding shares of stock of the Company entitled to vote thereon, voting together as a single class. Subject to the rights granted to Platinum under our amended and restated certificate of incorporation and the Investor Rights Agreement, any vacancy on our board of directors, including a vacancy resulting from an enlargement of our board of directors, may be filled only by vote of a majority of our directors then in office. In the event that (i) a vacancy is created at any time by the death, resignation, removal (with or without cause) or by any other cause of the selling stockholders’ nominee and (ii) the number of directors nominated by the selling stockholders is less than the number that the selling stockholders are entitled to nominate under our amended and restated certificate of incorporation and the Investor Rights Agreement, then such vacancy may be filled only by the selling stockholders unless otherwise agreed by Platinum.

Advance Notice for Raising Business or Making Nominations at Meetings

Our amended and restated bylaws establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors or a committee of the board of directors. In order for any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice requirements and provide us with certain information. Generally, to be timely, a stockholder’s notice must be received at our principal executive offices not less than 90 days nor more than 120 days prior to the first anniversary date of the immediately preceding annual meeting of stockholders. Our amended and restated bylaws also specify requirements as to the form and content of a stockholder’s notice. Our amended and restated bylaws allow the chairperson of the meeting at a meeting of the stockholders to adopt rules and regulations for the conduct of meetings which may have the effect of precluding the conduct of certain business at a meeting if the rules and regulations are not followed. These notice requirements do not limit Platinum or its affiliates’ rights under our amended and restated certificate of incorporation or the Investor Rights Agreement. These provisions and Delaware law may defer, delay or discourage a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to influence or obtain control of the Company.

19

Actions by Written Consent; Special Meetings of Stockholders

Pursuant to Section 228 of the DGCL, any action required to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action to be so taken, is signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of our stock entitled to vote thereon were present and voted, unless our amended and restated certificate of incorporation provides otherwise. Our amended and restated certificate of incorporation precludes stockholder action by written consent once Platinum and its affiliates beneficially own, in the aggregate, less than a majority of the voting power of all outstanding shares of our Common Stock.

Our amended and restated certificate of incorporation also provides that special meetings of our stockholders may be called at any time only by or at the direction of the board of directors or the chairperson of the board of directors; provided, however, that Platinum and its affiliates are permitted to call special meetings of our stockholders for so long as they hold, in the aggregate, at least a majority of the voting power of all outstanding shares of our Common Stock. Our amended and restated bylaws prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers or changes in control or management of the Company.

Amended and Restated Certificate of Incorporation and Bylaws

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together as a single class, is required to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage.

Our amended and restated certificate of incorporation provides that once Platinum and its affiliates beneficially own, in the aggregate, less than 50% of the voting power of all outstanding shares of stock entitled to vote generally in the election of directors, the following provisions in our amended and restated certificate of incorporation may be amended, altered, repealed or rescinded only by the affirmative vote of the holders of at least 66 and 2/3% in the voting power of all outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class:

•the provision requiring a 66 and 2/3% supermajority vote for stockholders to amend our amended and restated bylaws;

•the provisions providing for a classified board of directors (the election and term of our directors);

•the provisions regarding resignation and removal of directors;

•the provisions regarding entering into business combinations with interested stockholders;

•the provisions regarding stockholder action by written consent;

•the provisions regarding calling special meetings of stockholders;

•the provisions regarding filling vacancies on our board of directors and newly created directorships;

•the provisions eliminating monetary damages for breaches of fiduciary duty by a director;

•the provisions regarding competition and corporate opportunities; and

•the amendment provision requiring that the above provisions may be amended only with a 66 and 2/3% supermajority vote.

In addition, our amended and restated certificate of incorporation may not be amended, altered or repealed without the prior written consent of Platinum if such amendment, alteration or repeal would adversely affect the rights of Platinum under our amended and restated certificate of incorporation.

20

The combination of the classification of our board of directors, the lack of cumulative voting and the supermajority voting requirements make it more difficult for our existing stockholders to replace our board of directors, as well as for another party to obtain control of us by replacing our board of directors. Because our board of directors has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, our stockholders will have appraisal rights in connection with a merger or consolidation of us. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

Stockholders’ Derivative Actions

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Exclusive Jurisdiction of Certain Actions

Our amended and restated certificate of incorporation provides, subject to limited exceptions, that unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware is, to the fullest extent permitted by law, the sole and exclusive forum for any (i) derivative action or proceeding brought on behalf of the Company, (ii) action asserting a claim of breach of any fiduciary duty owed by, or other wrongdoing by, any director, officer or other employee of the Company to the Company or our stockholders, creditors or other constituents, or a claim of aiding and abetting any such breach of fiduciary duty, (iii) action asserting a claim against the Company or any director, officer or other employee of the Company arising pursuant to any provision of the DGCL or our amended and restated certificate of incorporation or our amended and restated bylaws, (iv) action to interpret, apply, enforce or determine the validity of the amended and restated certificate of incorporation, (v) action asserting a claim against the Company or any director, officer or other employee of the Company governed by the internal affairs doctrine or (vi) any other action asserting an “internal corporate claim,” as that term is defined in Section 115 of the DGCL; provided that, for the avoidance of doubt, the exclusive forum provision will not apply to suits brought to enforce any liability or duty created by the Securities Act, the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction. Our amended and restated certificate of incorporation also provides that, unless we consent in writing to the selection of an alternative forum, the U.S. federal district courts will be the exclusive forum for the resolution of any actions or proceedings asserting claims arising under the Securities Act. However, Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all suits brought to enforce a duty or liability created by the Securities Act or the rules and regulations thereunder. While the Delaware Supreme Court has upheld the validity of similar provisions under the DGCL, there is uncertainty as to whether a court in another state would enforce such a forum selection provision. Our exclusive forum provision does not relieve us of our duties to comply with the federal securities laws and the rules and regulations thereunder, and our stockholders are not deemed to have waived our compliance with these laws, rules and regulations. Any person or entity purchasing or otherwise acquiring any interest in shares of capital stock of the Company will be deemed to have received notice of and consented to the forum provisions in our amended and restated certificate of incorporation. For more information on the risks associated with our choice of forum provision, see “Risk Factors—Risks Related to this Offering and Ownership of Our Common Stock—Our amended and restated certificate of incorporation contains exclusive forum provisions that could limit our stockholders’ ability to pursue certain claims in a preferred judicial forum” in our 2025 Form 10-K which is incorporated by reference.

Business Combinations

We are not subject to the provisions of Section 203 of the DGCL. In general, Section 203 prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a three-

21

year period following the time that the person becomes an interested stockholder, unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns, or did own within three years prior to the determination of interested stockholder status, 15% or more of the corporation’s voting stock.

Under Section 203, a business combination between a corporation and an interested stockholder is prohibited unless it satisfies one of the following conditions:

•before the stockholder became an interested stockholder, our board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

•upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding certain shares; or

•at or after the time that the stockholder became an interested stockholder, the business combination was approved by our board of directors and by the affirmative vote of holders of at least two-thirds of our outstanding voting stock that was not owned by the interested stockholder.

A Delaware corporation may “opt out” of these provisions with an express provision in its original certificate of incorporation or an express provision in its certificate of incorporation or bylaws resulting from a stockholders’ amendment approved by at least a majority of the outstanding voting shares.

We opt out of Section 203; however, our certificate of incorporation contains similar provisions providing that we may not engage in certain “business combinations” with any “interested stockholder” for a three-year period following the time that the stockholder became an interested stockholder, unless:

•prior to such time, our board of directors approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder;

•upon consummation of the transaction that resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding certain shares; or

•at or subsequent to that time, the business combination was approved by our board of directors and by the affirmative vote of holders of at least 66 and 2/3% of our outstanding voting stock that was not owned by the interested stockholder.

Under certain circumstances, this provision will make it more difficult for a person who would be an “interested stockholder” to effect various business combinations with the Company for a three-year period. This provision may encourage companies interested in acquiring the Company to negotiate in advance with our board of directors because the stockholder approval requirement would be avoided if our board approves either the business combination or the transaction which results in the stockholder becoming an interested stockholder. These provisions also may have the effect of preventing changes in our board of directors and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Our amended and restated certificate of incorporation provides that Platinum and its affiliates, any of their respective direct or indirect transferees and any group as to which such persons are a party, do not constitute “interested stockholders” for purposes of this provision.

Limitations on Liability of Directors and Indemnification of Directors and Officers

The DGCL authorizes corporations to limit or eliminate the personal liability of directors or certain officers to the corporation and their stockholders for monetary damages for breaches of directors’ or officers’ fiduciary duties, subject to certain exceptions. Our amended and restated certificate of incorporation includes a provision that eliminates the personal liability of directors and certain officers for monetary damages for any breach of fiduciary

22

duty as a director or officer, except to the extent such liability or limitation thereof is not permitted under the DGCL. The effect of these provisions is to eliminate (1) our rights, and the rights of our stockholders, through stockholders’ derivative suits on our behalf, to recover monetary damages from a director for breach of fiduciary duty as a director and (2) our rights to recover monetary damages from certain officers for breach of fiduciary duty as an officer. However, exculpation does not apply to (1) a director or officer for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (2) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) a director or officer for any transaction from which the director or officer derived an improper personal benefit, (4) a director under Section 174 of the DGCL (regarding, among other things, the payment of unlawful dividends or unlawful stock purchases or redemptions) or (5) an officer in any action by or in the right of the corporation.

Our amended and restated bylaws provide that we must indemnify and advance expenses to our directors and officers to the fullest extent authorized by the DGCL. We also are expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for our directors, officers and certain associates for some liabilities. We believe that these indemnification and advancement provisions and insurance are useful to attract and retain qualified directors and executive officers.

The limitation of liability, indemnification and advancement provisions in our amended and restated certificate of incorporation and amended and restated bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit us and our stockholders. In addition, your investment may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

There is currently no pending material litigation or proceeding involving any of our directors, officers or associates for which indemnification is sought.

Corporate Opportunity

Delaware law permits corporations to adopt provisions renouncing any expectancy in or right to be offered an opportunity to participate in certain transactions or matters that may be investment, corporate or business opportunities and that are presented to a corporation or its officers, directors or stockholders. Our amended and restated certificate of incorporation, to the maximum extent permitted from time to time by Delaware law, renounces any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to our officers, directors or stockholders or their respective affiliates, other than those officers, directors, stockholders or affiliates who are our or our subsidiaries’ associates. Our amended and restated certificate of incorporation provides that, to the fullest extent permitted by law, Platinum or any of its affiliates or any director who is not employed by us (including any non-employee director who serves as one of our officers in both his or her director and officer capacities) or his or her affiliates will not have any duty to refrain from (i) engaging in a corporate opportunity in the same or similar lines of business in which we or our affiliates now engage or propose to engage or (ii) otherwise competing with us or our affiliates. In addition, to the fullest extent permitted by law, in the event that Platinum or any of its affiliates or any non-employee director acquires knowledge of a potential transaction or other business opportunity which may be a corporate opportunity for itself or himself or its or his affiliates or for us or our affiliates, such person will have no duty to communicate or offer such transaction or business opportunity to us or any of our affiliates and they may take any such opportunity for themselves or offer it to another person or entity. Our amended and restated certificate of incorporation does not renounce our interest in any business opportunity that is expressly offered to a non-employee director solely in his or her capacity as a director or officer of the Company. To the fullest extent permitted by law, no business opportunity will be deemed to be a potential corporate opportunity for us unless we would be permitted to undertake the opportunity under our amended and restated certificate of incorporation, we have sufficient financial resources to undertake the opportunity and the opportunity would be in line with our business.

PLAN OF DISTRIBUTION

We are registering the shares of Common Stock to sell from time to time after the date of this prospectus and to permit the resale of these shares of Common Stock by the selling stockholders from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by either selling stockholder of the shares of Common Stock.

The selling stockholders, which, as used herein includes donees, transferees or other successors-in-interest selling shares of Common Stock or interests in shares of Common Stock received after the date of this prospectus from the selling stockholders as a gift, pledge, partnership distribution or other transfer, may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of Common Stock or interests in shares of Common Stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices.

We or the selling stockholders may use any one or more of the following methods when disposing of shares or interests therein:

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

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

•purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•an exchange distribution in accordance with the rules of the applicable exchange;

•through one or more underwritten offerings on a firm commitment or best-efforts basis;

•privately negotiated transactions;

•short sales effected after the date the registration statement of which this prospectus is a part is declared effective by the SEC;

•through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•broker-dealers may agree with the selling stockholders to sell a specified number of such shares at a stipulated price per share;

•sales deemed to be an “at the market” offering as defined in Rule 415(a)(4) under the Securities Act, including without limitation sales made directly on any stock exchange on which the shares of Common Stock are listed, on any other existing trading market for the shares of Common Stock or to or through a market maker;

•a combination of any such methods of sale; and

•any other method permitted pursuant to applicable law.

The selling stockholders may also sell shares of Common Stock under Rule 144 under the Securities Act, if available, or in other transactions exempt from registration, rather than under this prospectus. The selling stockholders have the sole and absolute discretion not to accept any purchase offer or make any sale of shares of Common Stock if they deem the purchase price to be unsatisfactory at any particular time.

Based on information provided to us, as of the date of this prospectus, Ingram Holdco, LLC has pledged 177,478,218 shares of our Common Stock pursuant to the Margin Loan and related documentation on a non-recourse basis. The selling stockholders may, from time to time, pledge or grant a security interest in some or all of the shares of Common Stock owned by it that are not already pledged and, if they default in the performance of their

25

secured obligations, the pledgees or secured parties may offer and sell the shares of Common Stock, from time to time, under this prospectus, or under an amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer the shares of Common Stock in other circumstances, in which case the transferees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

In connection with the sale of our Common Stock or interests therein, the selling stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the Common Stock in the course of hedging the positions they assume. The selling stockholders may also sell shares of our Common Stock short and deliver these shares of Common Stock to close out their short positions, or loan or pledge the shares of Common Stock to broker-dealers that in turn may sell these shares of Common Stock. The selling stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of Common Stock offered by this prospectus, which Common Stock such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

We or the selling stockholders may also designate agents to solicit offers to purchase shares of Common Stock from time to time. If we or the selling stockholders utilize a dealer in the sale of the shares of Common Stock being offered by this prospectus, we or the selling stockholders will sell the shares of Common Stock to the dealer, as principal. The dealer may then resell the shares of Common Stock to the public at varying prices to be determined by the dealer at the time of resale.

If we or the selling stockholders utilize an underwriter in the sale of the shares of Common Stock being offered by this prospectus, we or the selling stockholders will execute an underwriting agreement with the underwriter at the time of sale and we will provide the name of any underwriter and a description of their compensation in the prospectus supplement that the underwriter will use to make resales of shares of Common Stock to the public. In connection with the sale of the shares of Common Stock, we or the selling stockholders or the purchasers of the shares of Common Stock for whom the underwriter may act as agent may compensate the underwriter in the form of underwriting discounts or commissions. The underwriter may sell the shares of Common Stock to or through dealers, and the underwriter may compensate those dealers in the form of discounts, concessions or commissions.

In compliance with guidelines of the Financial Industry Regulatory Authority (“FINRA”) the maximum consideration or discount to be received by any FINRA member or independent broker-dealer may not exceed 8% of the aggregate amount of shares of Common Stock offered pursuant to this prospectus and any applicable prospectus supplement. Underwriters, dealers and agents participating in the distribution of the shares of Common Stock may be deemed to be underwriters within the meaning of the Securities Act, and any discounts and commissions received by them and any profit realized by them on resale of the shares of Common Stock may be deemed to be underwriting discounts and commissions.

We are required to pay certain fees and expenses incurred by the selling stockholders incident to the registration of securities. We have agreed to indemnify the selling stockholders against certain liabilities, including liabilities under the Securities Act, relating to the registration of the shares offered by this prospectus. We may also indemnify underwriters, dealers and agents against certain liabilities, including liabilities under the Securities Act, or contribute to payments they may be required to make in respect thereof. In the event an offering made pursuant to this prospectus is subject to FINRA Rule 5121, the prospectus supplement will comply with a prominent disclosure provisions of that rule.

To facilitate the offering of the shares of Common Stock, certain persons participating in the offering may engage in transactions that stabilize, maintain or otherwise affect the price of the Common Stock. This may include over-allotments or short sales of the shares of Common Stock, which involves the sale by persons participating in the offering of more shares of Common Stock than we or the selling stockholders sold to them. In these circumstances, these persons would cover such over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of

26

the shares of Common Stock by bidding for or purchasing shares of Common Stock in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if the shares of Common Stock sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the Common Stock at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

We or the selling stockholders may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase the shares of Common Stock at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we or the selling stockholders pay for solicitation of these contracts.

Shares of Common Stock may also be exchanged for satisfaction of the selling stockholders’ obligations or other liabilities to their creditors. Such transactions may or may not involve brokers or dealers.

We agreed to cause the registration statement of which this prospectus is a part to remain effective for the period set forth in the Investor Rights Agreement. Shares of Common Stock will be sold only through registered or licensed brokers or dealers if required under applicable state securities laws. In addition, in certain states, the shares of Common Stock covered hereby may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and complied with.

To the extent required, the shares of our Common Stock to be sold, the names of the selling stockholders, the respective purchase prices and public offering prices, the names of any agents, dealer or underwriter, any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement that includes this prospectus.

Under applicable rules and regulations under the Exchange Act, any person engaged in the distribution of the resale shares of Common Stock may not simultaneously engage in market making activities with respect to the Common Stock for the applicable restricted period, as defined in Regulation M, prior to the commencement of the distribution. In addition, the selling stockholders will be subject to applicable provisions of the Exchange Act and the rules and regulations thereunder, including Regulation M, which may limit the timing of purchases and sales of the Common Stock by the selling stockholders or any other person. We will make copies of this prospectus available to the selling stockholders and have informed them of the need to deliver a copy of this prospectus to each purchaser at or prior to the time of the sale (including by compliance with Rule 172 under the Securities Act).

There can be no assurance that either of the selling stockholders will sell any or all of the shares of Common Stock we registered on behalf of the selling stockholders pursuant to the registration statement of which this prospectus forms a part.

Once sold under the registration statement of which this prospectus forms a part, the shares of Common Stock will be freely tradable in the hands of persons other than our affiliates.

LEGAL MATTERS

Certain legal matters with respect to the legality of the shares of Common Stock offered by the selling stockholders by this prospectus will be passed upon for us by Willkie Farr & Gallagher LLP, New York, New York.

EXPERTS

The financial statements and management’s assessment of the effectiveness of internal control over financial reporting (which is included in Management’s Report on Internal Control over Financial Reporting) incorporated in this prospectus by reference to the Annual Report on Form 10-K for the year ended December 27, 2025 have been so incorporated in reliance on the report (which contains an adverse opinion on the effectiveness of the Company’s internal control over financial reporting) of PricewaterhouseCoopers LLP (“PwC”), an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

PwC identified non-audit services impacting the period from January 2023 to August 2024. A member firm of PricewaterhouseCoopers International Limited (“PwC Member Firm”) and an unrelated third party jointly provided services, which included management functions at an immaterial branch of a wholly owned subsidiary of an entity under common control with the Company. These services were permissible under the applicable independence standards at the time the services were rendered but are inconsistent with SEC and Public Company Accounting Oversight Board (United States) independence rules. The services included remitting payments and filing documents with non-tax authorities on behalf of the branch.

PwC provided an overview of the facts and circumstances surrounding the non-audit services to the Audit Committee and the management team of the Company, including the entity involved, the nature of the non-audit services, the period over which they were provided, an approximation of the fees related to the non-audit services and other relevant factors.

The non-audit services were provided to an affiliate of the Company and not to the Company itself. None of the PwC Member Firm’s service engagement team members that performed the non-audit services have been or are members of the Company’s PwC audit engagement team. The non-audit services did not place PwC in a position of auditing its own work, did not result in PwC performing any decision-making or supervisory functions for the Company, and did not place PwC in a position of being an advocate for the Company. The fees received in connection with the non-audit services were approximately $5,500 and are immaterial to PwC, the PwC Member Firm and the entity to which the non-audit services were provided.

Considering the facts presented, the Audit Committee of the Company and PwC have concluded (i) that the non-audit services noted above did not and would not impair PwC’s application of objective and impartial judgment on any matter encompassed within PwC’s audit of the financial statements as of and for the years ended December 28, 2024, and December 30, 2023, and (ii) that no reasonable investor would conclude otherwise.

Item 15. Indemnification of Directors and Officers.

Section 102(b)(7) of the DGCL allows a corporation to eliminate the personal liability of a director or certain officers to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability for (1) a director or officer for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (2) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) a director or officer for any transaction from which the director or officer derived an improper personal benefit, (4) a director under Section 174 of the DGCL (regarding, among other things, the payment of unlawful dividends or unlawful stock purchases or redemptions) or (5) an officer in any action by or in the right of the corporation. Our amended and restated certificate of incorporation will contain a provision which eliminates directors’ and officers’ personal liability for monetary damages to the fullest extent permitted by the DGCL.

Our amended and restated certificate of incorporation and amended and restated bylaws provide in effect that we shall indemnify our directors and officers to the extent permitted by the DGCL. Section 145 of the DGCL provides that a Delaware corporation has the power to indemnify its directors, officers, associates and agents in certain circumstances. Subsection (a) of Section 145 of the DGCL empowers a corporation to indemnify any director, officer, employee or agent, or former director, officer, employee or agent, who was or is a party, or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection with such action, suit or proceeding, provided that such director, officer, employee or agent acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation and, with respect to any criminal action or proceeding, provided that such director, officer, employee or agent had no reasonable cause to believe that his or her conduct was unlawful.

Subsection (b) of Section 145 of the DGCL empowers a corporation to indemnify any director, officer, employee or agent, or former director, officer, employee or agent, who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that such person acted in any of the capacities set forth above, against expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of such action or suit provided that such person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, except that no indemnification may be made in respect of

II-1

any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action was brought shall determine that despite the adjudication of liability such person is fairly and reasonably entitled to indemnity for such expenses which the court shall deem proper.

Section 145 further provides that to the extent that a director or officer or employee of a corporation has been successful in the defense of any action, suit or proceeding referred to in subsections (a) and (b) of Section 145 or in the defense of any claim, issue or matter therein, he or she shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by him or her in connection therewith; that indemnification provided by Section 145 shall not be deemed exclusive of any other rights to which the party seeking indemnification may be entitled; and the corporation is empowered to purchase and maintain insurance on behalf of a director, officer, employee or agent of the corporation against any liability asserted against him or her or incurred by him or her in any such capacity or arising out of his or her status as such whether or not the corporation would have the power to indemnify him or her against such liabilities under Section 145; and that, unless indemnification is ordered by a court, the determination that indemnification under subsections (a) and (b) of Section 145 is proper because the director, officer, employee or agent has met the applicable standard of conduct under such subsections shall be made (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, (2) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion or (4) by the stockholders.

We expect to maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss arising from claims made by reason of breach of duty or other wrongful act and (2) to us with respect to indemnification payments that we may make to such directors and officers. In addition, in connection with the IPO we entered into indemnification agreements with each of our directors and officers. These indemnification agreements may require us, among other things, to indemnify each such director or officer, to the fullest extent permissible under Delaware law, against liabilities and for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by such director or officer in any action or proceeding arising out of his or her service as one of our directors or officers. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, we have been informed that in the opinion of the SEC such indemnification is against public policy and is therefore unenforceable.

Item 16. Exhibits and Financial Statement Schedules.

(a)Exhibits.

See the Exhibit Index immediately preceding the signature pages hereto, which is incorporated by reference as if fully set forth herein.

(b)Financial Statement Schedules.

Our audited consolidated financial statements, including the notes and schedules thereto, are incorporated by reference herein from the 2025 Form 10-K.

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

II-2

(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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in Exhibit 107 filed with 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;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(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 SEC by the registrant pursuant to Section 13 or Section 15(d) of 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 the 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 the 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-3

(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;

(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.

(b)The undersigned registrant hereby undertakes 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 Section 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.

(c)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 SEC 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.
