PRELIMINARY PROXY STATEMENT

SUBJECT TO COMPLETION, DATED OCTOBER 25, 2024

To the Shareholders of Perimeter Solutions, SA:

Our board of directors (the “Perimeter Luxembourg Board”) unanimously approved, on July 10, 2024, and is submitting to the holders of our ordinary shares (the “Existing Ordinary Shareholders”) and the holders of our preferred shares (the “Existing Preferred Shareholders” and, together with the Existing Ordinary Shareholders, the “Existing Shareholders”), for approval at an extraordinary general meeting of shareholders to be held on November 20, 2024 (the “Special Meeting”), a proposal that would result in the conversion (the “Redomiciliation Transaction”) of Perimeter Solutions, SA, a public limited liability company duly incorporated and validly existing under the laws of the Grand Duchy of Luxembourg, having its registered office at 28, Boulevard F.W. Raiffeisen, L-2411 Luxembourg, Grand Duchy of Luxembourg, and registered with the Registre de Commerce et des Sociétés, Luxembourg (Luxembourg Trade and Companies Register) under number B 256.548 (“Perimeter Luxembourg”), into a corporation incorporated under the laws of the State of Delaware, after which, Perimeter Luxembourg will continue as an entity under the name “Perimeter Solutions, Inc.” (“Perimeter Delaware”) and Existing Shareholders would hold shares in Perimeter Delaware rather than in a Luxembourg company.

We are pursuing the Redomiciliation Transaction for a number of reasons. In 2023 and 2024, the Perimeter Luxembourg Board and our management team undertook a review of our existing structure and operations, and particularly the jurisdiction of incorporation of Perimeter Luxembourg. We believe the Redomiciliation Transaction will enhance shareholder value over the long-term by simplifying the corporate structure to gain operational efficiencies. After considering various factors, the Perimeter Luxembourg Board believes that the Redomiciliation Transaction will enhance shareholder value over the long-term by providing potential strategic opportunities and benefits, including:

As described in this proxy statement/prospectus (this “Proxy/Prospectus”), the Existing Shareholders are being asked to consider and vote upon the Redomiciliation Transaction. On the effective date of the Redomiciliation Transaction, each of Perimeter Luxembourg’s currently issued (i) ordinary shares, with a nominal value of $1.00 per share (the “Existing Ordinary Shares”) and (ii) redeemable preferred shares, with a nominal value of $10.00 each, will automatically convert by operation of law on a one-for-one basis into (i) shares of common stock of Perimeter Delaware, par value $0.0001 per share (the “Common Stock”), and (ii) shares of preferred stock of Perimeter Delaware, par value $0.0001 per share (the “Preferred Stock”), respectively, in accordance with the terms of the certificate of incorporation of Perimeter Delaware to be filed with the Secretary of State of the State of Delaware (the “Proposed Charter”). Perimeter Luxembourg’s currently outstanding warrants to purchase ordinary shares of Perimeter Luxembourg (the “Existing Warrants”) are expected to expire on November 9, 2024, prior to the Special Meeting, and are therefore not expected to be converted into warrants to purchase Common Stock following the Redomiciliation Transaction. If we complete the Redomiciliation Transaction, we will continue our legal existence in Delaware as if we had originally been incorporated under Delaware law. Immediately after the Redomiciliation Transaction, the number of shares of Common Stock or Preferred Stock, as applicable, that you will own in Perimeter Delaware will be the same as the number of applicable Existing Shares you held in Perimeter Luxembourg immediately prior to the Redomiciliation Transaction.

The Existing Ordinary Shares are currently listed on the NYSE under the symbol “PRM” and the Existing Warrants are currently quoted on OTC Markets Group Inc. under the symbol “PRMFF.” We expect the Common

Stock to continue to trade under the same symbol on the NYSE following the Redomiciliation Transaction. We do not expect to have warrants listed for trading on any securities exchange or included in any automatic quotation system following the Redomiciliation Transaction as our Existing Warrants are expected to expire prior to the Special Meeting. The Existing Preferred Shares are not currently, and we do not intend for the Preferred Stock to be, listed for trading on any securities exchange or included in any automatic quotation system.

After the Redomiciliation Transaction, as we describe in this Proxy/Prospectus, your rights under Delaware corporate law as a holder of Common Stock or Preferred Stock, as applicable, will differ from your current rights under Luxembourg corporate law as a holder of Existing Shares. In addition, the Proposed Charter and the proposed bylaws of Perimeter Delaware to be adopted in connection with the Redomiciliation Transaction differ in some respects from Perimeter Luxembourg’s current Updated & Coordinated Articles of Association, as further described in this Proxy/Prospectus.

We currently anticipate that the Redomiciliation Transaction will become effective as soon as practicable following the Special Meeting. The Perimeter Luxembourg Board may delay or abandon the Redomiciliation Transaction at any time prior to convening the Special Meeting if it determines for any reason that the consummation of such transaction would be inadvisable or not in the best interests of our shareholders.

The accompanying Proxy/Prospectus provides you with detailed information regarding the Redomiciliation Transaction. We encourage you to read the entire Proxy/Prospectus carefully. IN PARTICULAR, YOU SHOULD CAREFULLY CONSIDER THE RISK FACTORS WE DESCRIBE STARTING ON PAGE 29 OF THE ACCOMPANYING PROXY/PROSPECTUS.

Only Existing Shareholders of record as of the close of business on September 23, 2024, are entitled to notice and have the right to attend the Special Meeting (or at any adjournment(s) or postponement(s) thereof that may take place, unless otherwise decided by the Perimeter Luxembourg Board) and vote their shares, or may grant a proxy to vote on the proposals included in this Proxy/Prospectus.

Existing Ordinary Shareholders and, as applicable, Existing Preferred Shareholders, will also be asked to vote on several proposals, including, among others, the approval of the Proposed Charter.

The date and time of the Special Meeting is November 20, 2024, at 2:00 p.m., Luxembourg time (8:00 a.m. New York City time), and the place of the Special Meeting is at the premises of the Maples Group at 12E, rue Guillaume Kroll, L-1882 Luxembourg, Grand Duchy of Luxembourg. The Perimeter Luxembourg Board has unanimously approved the Redomiciliation Transaction and recommends that you vote “FOR” all of the proposals to be presented at the Special Meeting. We urge you to join us in supporting these important initiatives.

As owners of Existing Shares, your vote is important, no matter how many shares you own. Whether or not you plan to attend the Special Meeting, unless otherwise communicated, please (1) with respect to Existing Ordinary Shareholders, (i) vote and submit your proxy by telephone or the internet following the instructions on the Proxy Card, or (ii) sign, date, and return the Proxy Card in the business-reply envelope included in your package, and (2) with respect to Existing Preferred Shareholders, sign, date, and return the voting form or the proxy separately provided to you.

Sincerely yours,

None of the SEC, any U.S. state securities commission nor any securities regulatory authority in Luxembourg has approved or disapproved of the Redomiciliation Transaction, the other transactions described in the accompanying Proxy/Prospectus, or any of the securities to be issued in connection with the Redomiciliation Transaction, and has not passed upon the merits or fairness of the Redomiciliation Transaction or related transactions or passed upon the adequacy or accuracy of the disclosure in the accompanying Proxy/Prospectus, or determined if the accompanying Proxy/Prospectus is truthful or complete. Any representation to the contrary is a criminal offense.

The date of this Proxy/Prospectus is     , 2024, and it will be first mailed to the Existing Shareholders on or about     , 2024.

A list of Existing Shareholders of Perimeter Luxembourg will be maintained and open for examination by any of its shareholders from ten days prior to the Special Meeting, for any purpose

germane to the Special Meeting, during regular business hours at our registered office at 28, Boulevard F.W.

Raiffeisen, L-2411 Luxembourg, Grand Duchy of Luxembourg, and registered with the Registre de Commerce et des Sociétés, Luxembourg (Luxembourg Trade and Companies Register) under number B 256.548 (“Perimeter Luxembourg”), unanimously approved, on July 10, 2024, and is submitting to the holders of Perimeter Luxembourg’s ordinary shares (the “Existing Ordinary Shareholders”) and the holders of Perimeter Luxembourg’s preferred shares (the “Existing Preferred Shareholders” and, together with the Existing Ordinary Shareholders, the “Existing Shareholders”) for approval at an extraordinary general meeting of shareholders to be held on November 20, 2024 (the “Special Meeting”), a proposal that would result in the conversion (the “Redomiciliation Transaction”) of Perimeter Luxembourg into a corporation incorporated under the laws of the State of Delaware, after which, Perimeter Luxembourg will continue as an entity under the name “Perimeter Solutions, Inc.” (“Perimeter Delaware”) and Existing Shareholders would hold shares in Perimeter Delaware rather than in a Luxembourg company.

On the effective date of the Redomiciliation Transaction, each of Perimeter Luxembourg’s currently issued (i) ordinary shares, with a nominal value of $1.00 per share (the “Existing Ordinary Shares”) and (ii) redeemable preferred shares, with a nominal value of $10.00 each (the “Existing Preferred Shares”), will automatically convert by operation of law on a one-for-one basis into (i) shares of common stock of Perimeter Delaware, par value $0.0001 per share (the “Common Stock”), and (ii) shares of preferred stock of Perimeter Delaware, par value $0.0001 per share (the “Preferred Stock”), respectively, in accordance with the terms of the certificate of incorporation of Perimeter Delaware to be filed with the Secretary of State of the State of Delaware.

RISK FACTORS

Shareholders should carefully consider the following risk factors, together with all of the other information included and incorporated by reference in this Proxy/Prospectus, before they decide whether to vote or instruct their vote to be cast to approve the proposals described in this Proxy/Prospectus.

You should carefully consider the following factors as well as the other information contained in and incorporated by reference into this Proxy/Prospectus, including the risks under the heading “Risk Factors” in Perimeter Luxembourg’s Annual Report on Form 10-K for the year ended December 31, 2023 and the other reports Perimeter Luxembourg files from time to time with the SEC that are incorporated by reference herein. For information about Perimeter Luxembourg’s filings incorporated by reference in this proxy statement/prospectus, see the section entitled “Where You Can Find More Information.”

The risks set out below are not exhaustive and do not comprise all of the risks associated with voting your shares. Additional risks and uncertainties not currently known to Perimeter Luxembourg or that Perimeter Luxembourg currently deems immaterial may also have a material adverse effect on Perimeter Delaware’s business, financial condition, results of operations, prospects, and/or share price. Shareholders should consult a legal adviser, an independent financial adviser, or a tax adviser for legal, financial, or tax advice prior to deciding whether to vote or instruct their vote to be cast to approve the proposals described in this Proxy/Prospectus.

Risks Relating to Perimeter Luxembourg’s Business

You should read and consider the risk factors specific to Perimeter Luxembourg’s business that will continue to affect Perimeter Delaware after completion of the Redomiciliation Transaction. These risks are described under the heading “Risk Factors” in Perimeter Luxembourg’s Annual Report on Form 10-K for the year ended December 31, 2023, which is incorporated by reference into this Proxy/Prospectus, and in other documents that are incorporated by reference into this Proxy/Prospectus.

Risks Relating to Perimeter Delaware

The rights of stockholders under Delaware law may differ from the rights of shareholders under Luxembourg law.

Currently, your rights as a shareholder of Perimeter Luxembourg arise under the laws of the Grand Duchy of Luxembourg, as well as the Existing Articles. Upon effectiveness of the Redomiciliation Transaction, your rights as a holder of Common Stock or Preferred Stock, as applicable, will arise under Delaware law, as well as the Proposed Organizational Documents. The Proposed Organizational Documents and Delaware law contain provisions that differ in certain respects from those in the Existing Articles and Luxembourg law and, therefore, some of your rights as a shareholder will change. For a description of your rights following the Redomiciliation Transaction and how they may differ from your current rights, please see “Comparison of Shareholder Rights Between Luxembourg Law and Delaware Law.” Forms of the Proposed Charter and Proposed Bylaws that will be effective upon completion of the Redomiciliation Transaction are attached as Annexes A and B, respectively, to this Proxy/Prospectus. We encourage you to read the Proposed Organizational Documents.

Anti-takeover provisions in the Proposed Organizational Documents could make an acquisition of us more difficult and limit attempts by our shareholders to replace or remove our current management.

In addition to protections afforded under the DGCL, the Proposed Organizational Documents will contain anti-takeover provisions that could have the effect of delaying or preventing changes in control or changes in

29

management or the Perimeter Delaware Board. The Proposed Organizational Documents, which will be effective upon completion of the Redomiciliation Transaction, include the following anti-takeover provisions:

For a comparison of how the provisions in the Proposed Organization Documents may differ from your current rights under the Existing Articles, see “Comparison of Shareholder Rights Between Luxembourg Law and Delaware Law.”

These anti-takeover provisions may frustrate or prevent any attempts by our shareholders to replace or remove our current management by making it more difficult for shareholders to replace members of the Perimeter Delaware Board, which will be responsible for appointing the members of our management, and may discourage, delay, or prevent a transaction involving a change in control of Perimeter Delaware that is in the best interest of our minority shareholders. Even in the absence of a takeover attempt, the existence of these provisions may adversely affect the prevailing market price of the Common Stock if shareholders view them as discouraging future takeover attempts.

The Proposed Organizational Documents will designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by stockholders, which could limit stockholders’ ability to obtain a favorable judicial forum for disputes with Perimeter Delaware or its directors or officers or other matters pertaining to Perimeter Delaware’s internal affairs.

The Proposed Organizational Documents will provide that, subject to limited exceptions and unless Perimeter Delaware consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for (i) any derivative action, suit or proceeding brought on behalf of the Perimeter Delaware, (ii) any action, suit or proceeding asserting a claim of breach of a fiduciary duty owed by any director, officer, or stockholder of Perimeter Delaware to Perimeter Delaware or to its stockholders, (iii) any action, suit or proceeding arising pursuant to any provision of the DGCL or the Proposed Organizational Documents (as either may be amended from time to time) or (iv) any action, suit or proceeding asserting a claim against Perimeter Delaware governed by the internal affairs doctrine.

The forum selection provision in the Proposed Organizational Documents does not apply to establish the Court of Chancery of the State of Delaware as the forum for actions or proceedings brought to enforce a duty or liability created by the Securities Act or the Exchange Act.

Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all claims brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder and our Proposed Organizational Documents will provide that the federal district courts of the United States of

30

America will, to the fullest extent permitted by law, be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While there can be no assurance that federal or state courts will determine that our federal forum provision should be enforced in a particular case, application of our federal forum provision means that suits brought by our stockholders to enforce any duty or liability created by the Securities Act must be brought in federal court and cannot be brought in state court.

Section 27 of the Exchange Act creates exclusive federal jurisdiction over all claims brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder and our Proposed Bylaws will provide that the federal district courts of the United States of America will, to the fullest extent permitted by law, be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Exchange Act. Accordingly, actions by our stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in federal court. Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder.

Any person or entity purchasing, otherwise acquiring or holding any interest in shares of capital stock of Perimeter Delaware will be deemed to have notice of, and consented to, these forum selection provisions. However, stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. Additionally, our stockholders cannot waive compliance with the federal securities laws and the rules and regulations thereunder. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with Perimeter Delaware or its directors, officers or other matters pertaining to Perimeter Delaware’s internal affairs, and may discourage lawsuits with respect to such claims. Alternatively, if a court were to find these provisions of the Proposed Organizational Documents inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, Perimeter Delaware may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect its business, financial condition, or operating results.

There can be no assurance that the Common Stock will be able to continue to satisfy the NYSE listing criteria following the Redomiciliation Transaction and the market price of the Common Stock may be subject to volatility.

The Existing Ordinary Shares are currently listed on the NYSE under the symbol “PRM.” We expect the Common Stock to continue to trade under the same symbol on the NYSE following the Redomiciliation Transaction. There is no assurance that Perimeter Delaware will be able to continue to satisfy the NYSE listing criteria following the consummation of the Redomiciliation Transaction. There can also be no assurance that the trading market for the Common Stock shares will continue to be as active or liquid as was the trading market for the Existing Ordinary Shares prior to the Redomiciliation Transaction or that the trading price of the Common Stock following the Redomiciliation Transaction may not be effectively lower than the trading price of the Existing Ordinary Shares.

As is the case with the Existing Ordinary Shares, the market price of the Common Stock may be volatile. The value of an investment in the Common Stock may decrease or increase abruptly, and such volatility may bear little or no relation to Perimeter Delaware’s performance. The price of the Common Stock may fall in response to market appraisal of Perimeter Delaware’s strategy or if its results of operations and/or prospects are below the expectations of market analysts or stockholders. In addition, stock markets have, from time to time, experienced significant price and volume fluctuations that have affected the market price of securities, and may, in the future, experience similar fluctuations which may be unrelated to Perimeter Delaware’s operating performance and prospects, but nevertheless affect the price of the Common Stock. This volatility may affect the ability of holders of Common Stock to sell these at an advantageous price. Broad market fluctuations, as well as economic conditions generally may adversely affect the market price of the Common Stock.

31

Risks Relating to the Redomiciliation Transaction

The expected benefits of the Redomiciliation Transaction may not be realized.

There can be no assurance that any or all of the anticipated benefits of the Redomiciliation Transaction will be achieved. Achieving the anticipated benefits of the Redomiciliation Transaction is subject to a number of risks and uncertainties, including factors that we do not and cannot control. In addition, if the expected benefits of the Redomiciliation Transaction do not meet expectations of investors or securities analysts, the price of the Common Stock following completion of the Redomiciliation Transaction may decline. For a description of the potential strategic opportunities and other benefits the Perimeter Luxembourg Board believes are afforded by the Redomiciliation Transaction, see “The Redomiciliation Proposal—Reasons for the Redomiciliation Transaction.”

The Redomiciliation Transaction is conditional and the conditions may not be satisfied, and the Perimeter Luxembourg Board may delay or abandon the Redomiciliation Transaction at any time prior to its effectiveness.

Completion of the Redomiciliation Transaction is conditional, among other things, upon the approval of the Redomiciliation Proposal by Existing Shareholders at the Special Meeting. The completion of the Redomiciliation Transaction is also conditioned upon the approval of the Common Stock for listing on the NYSE and the declaration of effectiveness by the SEC of the registration statement on Form S-4 to which this Proxy/Prospectus forms a part, among other conditions. Although Perimeter Luxembourg is diligently applying its efforts to take, or cause to be taken, all actions to do, or cause to be done, all things necessary, proper or advisable to obtain the requisite approvals, there can be no assurance that these conditions will be fulfilled or that the Redomiciliation Transaction will be completed.

Furthermore, the Perimeter Luxembourg Board has reserved the right to delay or abandon the Redomiciliation Transaction at any time prior to convening the Special Meeting if it determines for any reason that the consummation of such transaction would be inadvisable or not in the best interests of our shareholders.

Perimeter Luxembourg will allocate time and resources to effecting the Redomiciliation Transaction and incur non-recurring costs related thereto.

Perimeter Luxembourg and its management have allocated and will continue to be required to allocate time and resources to effect the completion of the Redomiciliation Transaction and related and incidental activities. There is a risk that the challenges associated with managing these various initiatives as described in this Proxy/Prospectus may have a business impact and that consequently the underlying businesses will not perform in line with expectations. This could have an adverse effect on the business, financial condition, and reputation of our Company before and after the Redomiciliation Transaction.

In addition, Perimeter Luxembourg expects to incur a number of significant non-recurring costs associated with the Redomiciliation Transaction, including legal fees, accountants’ fees, proxy solicitor fees, filing fees, mailing expenses, and financial printing expenses. There can be no assurance that the actual costs will not exceed those estimated and the actual completion of the Redomiciliation Transaction may result in additional and unforeseen expenses. The substantial majority of these costs will be incurred regardless of whether the Redomiciliation Transaction is completed and prior to your vote to adopt the Redomiciliation Proposal at the Special Meeting. While it is expected that benefits of the Redomiciliation Transaction achieved by Perimeter Delaware will offset these transaction costs over time, this net benefit may not be achieved in the short-term or at all, particularly if the domestication is delayed or does not happen at all. The Perimeter Luxembourg Board may decide to defer or abandon the Redomiciliation Transaction at any time prior to convening the Special Meeting. In addition, after the Redomiciliation Proposal is adopted by the Existing Shareholders, we will not effect the domestication if one of the conditions to the Redomiciliation Transaction fails to be satisfied.

Negative publicity resulting from the Redomiciliation Transaction could adversely affect the Company’s business and the market price of the Existing Ordinary Shares prior to the domestication and the Common Stock

32

following the domestication. Domestications that have been undertaken by other companies have in some cases generated significant news coverage, some of which has been negative. Negative publicity generated by the Redomiciliation Transaction could cause certain persons with whom Perimeter Luxembourg has a business relationship to be more reluctant to do business with Perimeter Luxembourg prior to the domestication or Perimeter Delaware following the domestication. Negative publicity could also cause some Existing Ordinary Shareholders to sell their Existing Ordinary Shares or decrease the demand for new investors to purchase such shares, which could have an adverse impact on the price of the Existing Ordinary Shares.

The Redomiciliation Transaction may result in material Luxembourg taxes for Perimeter Luxembourg or Perimeter Delaware.

Perimeter Luxembourg and its management have engaged professional tax advisors who have assessed that no material corporate-level Luxembourg taxes should be expected for Perimeter Luxembourg or Perimeter Delaware in the context of the Redomiciliation Transaction. However, the Luxembourg tax authorities may assert, or a Luxembourg court may sustain, a contrary position, and no assurances can be given that the Redomiciliation Transaction will not result in material corporate-level Luxembourg taxes for Perimeter Luxembourg or Perimeter Delaware. For more information about the tax considerations with respect to such matters, see “Luxembourg Tax Considerations.”

The Redomiciliation Transaction may result in adverse tax consequences for U.S. holders of Existing Ordinary Shares, Existing Preferred Shares and Existing Warrants.

As discussed more fully under “U.S. Federal Income Tax Considerations,” it is intended that the Redomiciliation Transaction qualify as a reorganization (an “F Reorganization”) within the meaning of Section 368(a)(l)(F) of the Code. However, Perimeter Luxembourg has not sought, and does not intend to seek, any ruling from the Internal Revenue Service (“IRS”) with respect to the qualification of the Redomiciliation Transaction as an F Reorganization. No assurance can be given that the IRS will agree with the views expressed herein, or that a court will not sustain any challenge by the IRS in the event of litigation. If the Redomiciliation Transaction fails to qualify as an F Reorganization, a U.S. Holder (as defined in “U.S. Federal Income Tax Considerations —U.S. Holders”) of Perimeter Luxembourg Securities (as defined in “U.S. Federal Income Tax Considerations”) generally would recognize gain or loss with respect to its Perimeter Luxembourg Securities in an amount equal to the difference, if any, between the fair market value of the corresponding Perimeter Delaware Securities (as defined in “U.S. Federal Income Tax Considerations”) received in the Redomiciliation Transaction and the U.S. Holder’s adjusted tax basis in its Perimeter Luxembourg Securities surrendered.

Assuming that the Redomiciliation Transaction qualifies as an F Reorganization, subject to the PFIC rules discussed under “U.S. Federal Income Tax Considerations — U.S. Holders — Tax Effects of the Redomiciliation Transaction to U.S. Holders — PFIC Considerations,” U.S. Holders generally will be subject to Section 367(b) of the Code. A U.S. Holder whose Existing Shares, on the date of the Redomiciliation Transaction, have a fair market value of less than $50,000 and who, on the date of the Redomiciliation Transaction, beneficially owns (actually or constructively) less than 10% of the total combined voting power of all classes of Perimeter Luxembourg stock entitled to vote and less than 10% of the total value of all classes of Perimeter Luxembourg stock generally will not recognize any gain or loss and will not be required to include any part of Perimeter Luxembourg’s earnings and profits in income as a result of the Redomiciliation Transaction. A U.S. Holder whose public shares, on the date of the Redomiciliation Transaction, have a fair market value of $50,000 or more and, who on the date of the Redomiciliation Transaction, beneficially owns (actually or constructively) less than 10% of the total combined voting power of all classes of Perimeter Luxembourg stock entitled to vote and less than 10% of the total value of all classes of Perimeter Luxembourg stock, generally will recognize gain (but not loss) in respect of the Redomiciliation Transaction as if such U.S. Holder exchanged its Existing Shares for shares of Common Stock and Preferred Stock in a taxable transaction, unless such U.S. Holder elects in accordance with applicable Treasury Regulations to include in income as a deemed dividend deemed paid by Perimeter Luxembourg the “all earnings and profits amount” (as defined in the

33

Treasury Regulations under Section 367 of the Code) attributable to the public shares held directly by such U.S. Holder. A U.S. Holder who, on the day of the Redomiciliation Transaction, beneficially owns (actually or constructively) 10% or more of the total combined voting power of all classes of Perimeter Luxembourg stock entitled to vote or 10% or more of the total value of all classes of Perimeter Luxembourg stock, generally will be required to include in income as a deemed dividend deemed paid by Perimeter Luxembourg the “all earnings and profits amount” (as defined in the Treasury Regulations under Section 367 of the Code) attributable to the Existing Shares held directly by such U.S. Holder as a result of the Redomiciliation Transaction. Perimeter Luxembourg expects to have a deficit in earnings and profits on the date of the Redomiciliation Transaction. However, it is possible that, notwithstanding Perimeter Luxembourg’s expectations, the amount of Perimeter Luxembourg’s cumulative net earnings and profits could be positive through the date of the Redomiciliation Transaction. Therefore, there can be no assurance that Perimeter Luxembourg will indeed have a deficit in earnings and profits on the date of the Redomiciliation Transaction.

U.S. Holders should consult their tax advisors for the tax consequences of the Redomiciliation Transaction to their particular situations. For a more detailed description of the U.S. federal income tax consequences associated with the Redomiciliation Transaction, see “U.S. Federal Income Tax Considerations —U.S. Holders — Tax Effects of the Redomiciliation Transaction to U.S. Holders” And “U.S. Federal Income Tax Considerations — Non-U.S. Holders — Tax Effects of the Redomiciliation Transaction to Non-U.S. Holders.”

Following the Redomiciliation Transaction, non-U.S. holders of Existing Ordinary Shares, Existing Preferred Shares, and Existing Warrants will generally be subject to U.S. withholding tax up to 30% on distributions or deemed distributions treated as dividends for U.S. federal income tax purposes.

Non-U.S. Holders (as defined in “U.S. Federal Income Tax Considerations — Non-U.S. Holders”) will generally become subject to withholding tax at 30% (unless reduced under any applicable United States income tax treaty) on any distributions or deemed distributions treated as dividends for U.S. federal income tax purposes paid on Perimeter Delaware Securities after the Redomiciliation Transaction.

34

SHARE INFORMATION

The Existing Ordinary Shares are currently listed on the NYSE under the symbol “PRM” and the Existing Warrants are currently quoted on the OTC Market under the symbol “PRMFF.” We expect the Common Stock to continue to trade under the same symbol on the NYSE following the Redomiciliation Transaction. There is no assurance that Perimeter Delaware will be able to continue to satisfy the NYSE listing criteria following the consummation of the Redomiciliation Transaction. We do not expect to have warrants listed for trading on any securities exchange or included in any automatic quotation system following the Redomiciliation Transaction as our Existing Warrants are expected to expire prior to the Special Meeting. The Existing Preferred Shares are not currently, and we do not intend for the Preferred Stock to be, listed for trading on any securities exchange or included in any automatic quotation system.

On October July 30, 2024, the last trading day before Perimeter Luxembourg publicly disclosed its intention to redomicile to Delaware, the closing price of the Existing Ordinary Shares was $9.32 per share. On     , 2024, the last practicable date before the date of this Proxy/Prospectus, the closing price of the Existing Ordinary Shares was $     per share.

Holders of Record

As of the Record Date, there were 27 holders of record of Existing Ordinary Shares and Existing Ordinary Shareholders were entitled to vote an aggregate of 145,221,178 Existing Ordinary Shares. As of the Record Date, there were 23 holders of record of Existing Preferred Shares and Existing Preferred Shareholders were entitled to vote an aggregate of 10,000,000 Existing Preferred Shares.

Dividend Information

To date, Perimeter Luxembourg has not paid any dividends on its Existing Ordinary Shares.

In deciding whether to recommend any future dividend on the Common Stock, the Perimeter Delaware Board would take into account any legal or contractual limitation, our actual and anticipated future earnings, cash flows, debt service, and capital requirements, our business plans and such other matters as the Perimeter Delaware Board believes appropriate, in its discretion. We anticipate that any available cash will be retained by us to satisfy our operational and other cash needs. Accordingly, we do not expect to pay any cash dividend on shares of Common Stock in the foreseeable future.

COMPARISON OF SHAREHOLDER RIGHTS BETWEEN

LUXEMBOURG LAW AND DELAWARE LAW

Currently, your rights as a shareholder of Perimeter Luxembourg arise under the principal legislation governing companies registered in Luxembourg, which is the Luxembourg Company Law, as well as our Existing Articles of Association. Upon effectiveness of the Domestication, your rights as a shareholder of Perimeter Delaware, as well as the duties and responsibilities of directors of Perimeter Delaware, will arise under the DGCL, our Proposed Charter, and Proposed Bylaws.

The DGCL and the Proposed Organizational Documents contain provisions that differ in certain respects from the Luxembourg Company Law and our Existing Articles of Association and, therefore, some of your rights as a shareholder will change.

Below is a summary chart outlining important similarities and differences in the corporate governance and shareholder rights associated with each of the Luxembourg Company Law and the DGCL, as well as the Existing Articles of Association and the Proposed Organizational Documents. This summary is not an exhaustive review of the Luxembourg Company Law, the DGCL, the Existing Articles of Association or the Proposed Organizational Documents. You also should review the full text of the Proposed Charter and Proposed Bylaws that are attached to this proxy statement/prospectus as Annex A and Annex B, respectively, as well as the Luxembourg Company Law, the DGCL, and the regulations thereunder to understand how these laws apply to the shareholders of Perimeter Luxembourg before the Domestication and of Perimeter Delaware after the Domestication.

EXTRAORDINARY GENERAL MEETING OF PERIMETER LUXEMBOURG SHAREHOLDERS

General

Perimeter Luxembourg is furnishing this Proxy/Prospectus to Existing Shareholders as part of the solicitation of proxies by the Perimeter Luxembourg Board for use at the Special Meeting and at any adjournment or postponement thereof. This Proxy/Prospectus provides Existing Shareholders with information they need to know in order to be able to vote or instruct their vote to be cast at the Special Meeting.

Purpose of the Special Meeting

At the Special Meeting, Perimeter Luxembourg is asking Existing Ordinary Shareholders and Existing Preferred Shareholders, as applicable, to vote on the following proposals:

(1) The Redomiciliation Proposal — To consider and vote upon a proposal to approve by special resolution the change of Perimeter Luxembourg’s jurisdiction of incorporation from the Grand Duchy of Luxembourg to the State of Delaware, subject to the conditions set forth in such resolution, by transferring the registered office and place of central administration from the Grand Duchy of Luxembourg to the State of Delaware and, as a result, continuing and domesticating as a corporation incorporated under the laws of the State of Delaware, after which, Perimeter Luxembourg will continue as an entity under the name “Perimeter Solutions, Inc.” without any discontinuation of its legal existence, without liquidation or dissolution, and without creating a new legal entity;

(2) The Organizational Documents Proposal — To consider and vote upon a proposal to approve by special resolution, assuming the Redomiciliation Proposal is approved and adopted, the replacement of the Existing Articles with the Proposed Charter to be filed with the Secretary of State of the State of Delaware on the effective date of the Redomiciliation Transaction, including, among other things, adopting Delaware as the exclusive forum for certain stockholder litigation; and

(3) The Delegation of Authority Proposal — To grant power and authority to any director of Perimeter Luxembourg and/or any lawyer or employee of the law firm Maples and Calder (Luxembourg) SARL and/or any employee or clerk of the instrumenting notary in the Grand Duchy of Luxembourg, to individually carry out, with full power of substitution and sub-delegation, in the name and on behalf of Perimeter Luxembourg, any changes required by the matters set out under the proposals described in this Proxy/Prospectus as well as all filings, notifications and publications necessary for the Redomiciliation Transaction.

Recommendation to Existing Shareholders

The Perimeter Luxembourg Board believes that the Redomiciliation Proposal and the other proposals to be presented at the Special Meeting are fair to, and in the best interest of, the Existing Shareholders and unanimously recommends that its shareholders vote “FOR” all of the proposals to be presented at the Special Meeting.

Existing Shareholders; Record Date

As of the Record Date, which is September 23, 2024, there were (i) 27 holders of record of Existing Ordinary Shares and Existing Ordinary Shareholders were entitled to vote an aggregate of 145,221,178 Existing Ordinary Shares and (ii) 23 holders of record of Existing Preferred Shares and Existing Preferred Shareholders were entitled to vote an aggregate of 10,000,000 Existing Preferred Shares.

Date, Time and Place of Special Meeting

The Special Meeting will be held at 2:00 p.m. Luxembourg time (8:00 a.m. New York City time), on November 20, 2024, at the premises of the Maples Group at 12E, rue Guillaume Kroll, L-1882 Luxembourg, Grand Duchy of Luxembourg.

50

Voting Power

Existing Shareholders will be entitled to vote or direct votes to be cast at the Special Meeting if they owned Existing Shares on the Record Date for the Special Meeting. With respect to the Existing Ordinary Shares, voting on all resolutions at the Special Meeting will be conducted by way of telephone, internet, or Proxy Card or by vote in person. Existing Ordinary Shareholders will have one vote for each Existing Share owned as of the Record Date. With respect to the Existing Preferred Shares, voting on all resolutions at the Special Meeting will be conducted by way of voting forms, proxy or by vote in person. Existing Preferred Shareholders will have ten votes for each Existing Preferred Share owned as of the Record Date.

If your shares are held in “street name” or are in a margin or similar account, which means your shares are held of record by a broker, bank or nominee, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you should request from your broker a certificate or confirmation certifying the number of Existing Ordinary Shares recorded in their account on the Record Date or any other proof of ownership in a form acceptable to Perimeter Luxembourg at its own and full discretion. In order to vote, you must instruct your broker, bank or other nominee how to vote the shares you beneficially own in accordance with the voting instruction form you receive from your broker, bank or other nominee. If you wish to attend the Special Meeting and vote directly, you must contact your broker, bank or other nominee that appears as the registered shareholder on the Record Date to issue a legal proxy, which allows you as beneficial owner to vote his or her shares directly. Beneficial investors who own their investments through a bank or broker will need to contact their respective bank or broker before the Special Meeting.

Existing Warrants do not have voting rights.

Quorum and Vote of Existing Shareholders

Pursuant to the Existing Articles and in accordance with Luxembourg Company Law, the Redomiciliation Proposal and the Organizational Documents Proposal must be effected by the affirmative vote of at least two-thirds of the votes validly cast at the Special Meeting, provided that at least one half of the issued shares of Perimeter Luxembourg to which voting rights are attached pursuant to the Existing Articles or Luxembourg Company Law is present or represented at the Special Meeting. Existing Ordinary Shareholders and Existing Preferred Shareholder, voting as separate classes, are entitled to vote on the Redomiciliation Proposal and the Organizational Documents Proposal. If such quorum is not present at the Special Meeting, a second extraordinary general meeting may be convened and resolutions would be adopted at such extraordinary general meeting, irrespective of the number of Existing Ordinary Shares (and, as applicable, Existing Preferred Shares), present or represented, by the affirmative vote of at least two-thirds of the votes validly cast.

Pursuant to the Existing Articles and in accordance with Luxembourg Company Law, the Delegation of Authority Proposal must be effected by the affirmative vote of at least one half of the votes validly cast at the Special Meeting, provided that at least one half of the issued shares of Perimeter Luxembourg to which voting rights are attached pursuant to the Existing Articles or Luxembourg Company Law is present or represented at the Special Meeting. Only Existing Ordinary Shareholders are required to vote on the Delegation of Authority Proposal.

Abstentions and Broker Non-Votes

Proxy Cards that are marked “ABSTAIN” and proxies relating to “street name” shares that are returned to Perimeter Luxembourg but marked by brokers as “not voted” will be treated as shares present for purposes of determining the presence of a quorum on all matters, but will not be treated as votes cast and will, therefore, not affect the outcome of the vote on the proposals. If a shareholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on “non-routine” proposals. The matters to be voted upon at the Special Meeting are “non-routine” proposals.

51

Share Ownership of and Voting by Perimeter Luxembourg Directors and Officers

As of the Record Date, our directors and executive officers and their affiliates directly owned, in the aggregate, approximately 12,694,492 Existing Ordinary Shares. This represents approximately 8.7% of the Existing Ordinary Shares. As of the Record Date, there were 23 holders of record of Existing Preferred Shares and Existing Preferred Shareholders were entitled to vote an aggregate of 10,000,000 Existing Preferred Shares. As of the Record Date, our directors and executive officers and their affiliates directly owned, in the aggregate, approximately 194,462 of such shares. This represents approximately 2% of the Existing Preferred Shares. Our directors and executive officers have indicated that they intend to vote their shares in favor of the Redomiciliation Proposal at the Special Meeting, although none of them have entered into any agreements obligating them to do so.

Existing Preferred Shareholder Vote

Existing Preferred Shareholders, voting as a separate class, are entitled to vote on the Redomiciliation Proposal and the Organizational Documents Proposal.

THE REDOMICILIATION PROPOSAL

Overview

We are asking Existing Shareholders to adopt the Redomiciliation Proposal to change the jurisdiction of incorporation of Perimeter Luxembourg from the Grand Duchy of Luxembourg to the State of Delaware, upon which Perimeter Luxembourg will continue as an entity under the name “Perimeter Solutions, Inc.” and Existing Shareholders would hold shares in Perimeter Delaware rather than in a Luxembourg company. If the Existing Shareholders vote to adopt the Redomiciliation Proposal, and the other conditions to completion of the Redomiciliation Transaction are satisfied, Perimeter Luxembourg anticipates that, as soon as practicable following the Special Meeting, it will complete the domestication in accordance with articles 100-2, 100-3 and 1300-2 of the Luxembourg Company Law, the procedures of article 450-3 and following of the Luxembourg Company Law and the domestication procedures of Section 388 of the DGCL.

Immediately after the Redomiciliation Transaction, the number of shares of Common Stock or Preferred Stock, as applicable, that you will own in Perimeter Delaware will be the same as the number of applicable Existing Shares you held in Perimeter Luxembourg immediately prior to the Redomiciliation Transaction. Further, the number of outstanding shares of Common Stock and Preferred Stock will be the same as the number of outstanding Existing Ordinary Shares and Existing Preferred Shares, respectively, immediately before consummation of the Redomiciliation Transaction. Therefore, the Redomiciliation Transaction will not dilute your economic interest in Perimeter Delaware relative to your current interest in Perimeter Luxembourg. After the Redomiciliation Transaction, Perimeter Delaware will continue to conduct the same businesses as conducted by Perimeter Luxembourg before the Redomiciliation Transaction.

Reasons for the Redomiciliation Transaction

We are pursuing the Redomiciliation Transaction for a number of reasons. In 2023 and 2024, the Perimeter Luxembourg Board and our management team undertook a review of our existing structure and operations, and particularly the jurisdiction of incorporation of Perimeter Luxembourg. We believe the Redomiciliation Transaction will enhance shareholder value over the long-term by simplifying the corporate structure to gain operational efficiencies. After considering various factors, the Perimeter Luxembourg Board believes that the Redomiciliation Transaction will enhance shareholder value over the long-term by providing potential strategic opportunities and benefits, including:

56

57

As a result of the foregoing advantages of domestication in Delaware, the Perimeter Luxembourg Board believes that the domestication will generally improve Perimeter Delaware’s operational and financial flexibility and provide for a more efficient corporate structure to achieve strategic and financial goals. Further, the Perimeter Luxembourg Board believes that any direct benefit that the domestication in Delaware provides to Perimeter Delaware also indirectly benefits the shareholders, who are the owners of Perimeter Delaware.

Nevertheless, we cannot assure you that the anticipated benefits of the Redomiciliation Transaction will be realized. Although we expect the Redomiciliation Transaction to provide us with the benefits described above, the Redomiciliation Transaction will expose Perimeter Delaware and its shareholders to some risks. The Perimeter Luxembourg Board considered a variety of negative factors, including the possibility of uncertainty created by the Redomiciliation Transaction and the change in our legal domicile, the fact that we expect to incur costs to complete the Redomiciliaiton Transaction, the fact that Delaware corporate law imposes different and additional obligations on us, and other risks discussed in the discussion under “Risk Factors.”

Steps to the Redomiciliation Transaction

The Redomiciliation Transaction will, if completed, be consummated by means of a series of steps, as follows:

The conversion of Existing Ordinary Shares and Existing Preferred Shares into Common Stock and Preferred Stock will occur automatically upon effectiveness of the Delaware Filings.

Conditions to the Redomiciliation Transaction

In addition to the approval of the Redomiciliation Proposal, Perimeter Luxembourg’s ability to initiate the Delaware Filings necessary to effectuate the Redomiciliation Transaction is conditioned on the following matters:

58

If any of these conditions are not satisfied or waived by the Perimeter Luxembourg Board, then the Redomiciliation Transaction will not be effectuated and the Proposed Organizational Documents will not become effective. In addition, the expected timing for the completion of the Redomiciliation Transaction may be impacted by these or other conditions described in this Proxy/Prospectus. We cannot be certain when, or if, the conditions to the Redomiciliation Transaction will be satisfied or waived, or that the Redomiciliation Transaction will be completed.

Delay; Termination

The Perimeter Luxembourg Board has reserved the right to delay or abandon the Redomiciliation Transaction at any time prior to convening the Special Meeting if it determines for any reason that the consummation of such transaction would be inadvisable or not in the best interests of our shareholders.

Exchange of Existing Shares; Treatment of Existing Warrants

If the Redomiciliation Proposal is adopted by the requisite vote of our Existing Shareholders and the Redomiciliation Transaction is completed, then, on the effective date of the Redomiciliation Transaction, each of Perimeter Luxembourg’s currently issued (i) Existing Ordinary Shares and (ii) Existing Preferred Shares will automatically convert by operation of law on a one-for-one basis into (i) shares of Common Stock and (ii) shares of Preferred Stock, respectively, in accordance with the terms of the Proposed Charter.

Beneficial holders of Existing Ordinary Shares held in “street name” through a bank, broker or other nominee and record owners of shares held in book-entry form will not be required to take any action. Your ownership of shares of Common Stock or Preferred Stock, as applicable, will be recorded in book-entry form by your nominee (for shares held in “street name”) or by the Transfer Agent or the Company (for shares held by record owners in book-entry form), without the need for any additional action on your part. Holders of record who hold their shares in book-entry form will receive a statement of their holdings in Perimeter Delaware after the Redomiciliation Transaction.

Stock certificates representing Existing Shares will, at the effective time of the Redomiciliation Transaction, automatically represent the same number of shares of Common Stock or Preferred Stock, as applicable. You will not be required to exchange your stock certificates as a result of the Redomiciliation Transaction. If you desire to sell some or all of your shares of Common Stock or Preferred Stock after the effective time of the Redomiciliation Transaction, delivery of the stock certificate or certificates that previously represented Existing Shares will be sufficient.

Following the Redomiciliation Transaction, certificates bearing the name of Perimeter Delaware will be issued in the normal course upon surrender of outstanding Existing Share certificates for transfer or exchange. Holders who submit Existing Share certificates for transfer or exchange following the Redomiciliation Transaction will receive shares of Common Stock or Preferred Stock, as applicable, in book-entry form unless otherwise requested.

The Existing Warrants are expected to expire on November 9, 2024, prior to the Special Meeting, and are therefore not expected to be converted into warrants to purchase Common Stock of Perimeter Delaware following the Redomiciliation Transaction.The Existing Ordinary Shares are currently listed on the NYSE under

59

the symbol “PRM” and the Existing Warrants are currently quoted on the OTC Market under the symbol “PRMFF.” We expect the Common Stock to continue to trade under the same symbol on the NYSE following the Redomiciliation Transaction. There is no assurance that Perimeter Delaware will be able to continue to satisfy the NYSE listing criteria following the consummation of the Redomiciliation Transaction. We do not expect to have warrants listed for trading on any securities exchange or included in any automatic quotation system following the Redomiciliation Transaction as our Existing Warrants are expected to expire prior to the Special Meeting. The Existing Preferred Shares are not currently, and we do not intend for the Preferred Stock to be, listed for trading on any securities exchange or included in any automatic quotation system.

Employee Benefit Plans; 2021 Equity Plan; Incentive Awards

In connection with the Redomiciliation Transaction, Perimeter Delaware will automatically assume all compensation or benefit plans, policies, and arrangements maintained by Perimeter Luxembourg, including the 2021 Equity Plan. The 2021 Equity Plan provides for the grant of stock options (either incentive or non-qualified), stock appreciation rights, restricted stock, restricted stock units, performance shares, performance share units and other share-based incentive awards. Employees, directors and certain consultants of Perimeter Luxembourg are eligible to receive awards under the 2021 Equity Plan. Eligibility for options intended to be incentive stock options (“ISOs”) is limited to employees of Perimeter Luxembourg or any of its subsidiaries. A total of 32,000,000 Existing Ordinary Shares are authorized and reserved for issuance under the 2021 Equity Plan. Any shares reserved and available for issuance under the 2021 Equity Plan may be used for any type of award under the 2021 Equity Plan, including ISOs. As of October 22, 2024, 15,234,171 Existing Ordinary Shares were subject to outstanding incentive awards under the 2021 Equity Plan and 16,765,829 shares remained available for future grants under the plan.

Approval of the Redomiciliation Transaction would constitute approval of Perimeter Delaware’s assumption of the compensation and benefit plans, policies, and arrangements maintained by Perimeter Luxembourg. The 2021 Equity Plan will be continued by Perimeter Delaware following the Redomiciliation Transaction and Perimeter Delaware may grant incentive awards, including ISOs, to eligible participants under the plan. The total number of shares authorized and reserved for issuance under the 2021 Equity Plan, including the shares available for issuance pursuant to ISOs will continue to be 32,000,000, except the security available for issuance pursuant to incentive awards under the 2021 Equity Plan will be Common Stock rather than Existing Ordinary Shares.

Each outstanding Perimeter Luxembourg restricted stock unit, non-qualified stock option and other share-based incentive awards will be converted to an equivalent Perimeter Delaware incentive award. The incentive awards granted by Perimeter Delaware will be subject to the same terms and conditions as the converted Perimeter Luxembourg incentive awards (including performance-based vesting conditions), except the security issuable upon exercise or settlement of the Perimeter Delaware incentive award will be Common Stock (or its cash equivalent) rather than Existing Ordinary Shares (or its cash equivalent).

Interests of Certain Persons in the Redomiciliation Transaction

We do not believe that any of our directors or executive officers has an interest in the Redomiciliation Transaction that is different from the interests of our Existing Shareholders. No change in control payments or additional compensation will be payable to our directors or executive officers in connection with such domestication.

As of the Record Date, there were 27 holders of record of Existing Ordinary Shares and Existing Ordinary Shareholders were entitled to vote an aggregate of 145,221,178 Existing Ordinary Shares. As of the Record Date, our directors and executive officers and their affiliates directly owned, in the aggregate, approximately 12,694,492 of such shares. This represents approximately 8.7% of the Existing Ordinary Shares. As of the Record Date, there were 23 holders of record of Existing Preferred Shares and Existing Preferred Shareholders were entitled to vote an aggregate of 10,000,000 Existing Preferred Shares. As of the

60

Record Date, our directors and executive officers and their affiliates directly owned, in the aggregate, approximately 194,462 of such shares. This represents approximately 2% of the Existing Preferred Shares. Our directors and executive officers have indicated that they intend to vote their shares in favor of the Redomiciliation Proposal at the Special Meeting, although none of them have entered into any agreements obligating them to do so.

Existing Preferred Shareholder Vote

Existing Preferred Shareholders, voting as a separate class, are entitled to vote on the Redomiciliation Proposal. As of the date of this Proxy/Prospectus, holders of approximately 9.7 million Existing Preferred Shares, representing approximately 97% of the Existing Preferred Shares, have submitted votes in favor of the Redomiciliation Proposal via voting forms. Such voting forms will be tabled at the Special Meeting and, as a result, the required quorum and voting majority for the Existing Preferred Shareholders, voting as a separate class, is expected to be satisfied.

Redemption Rights

There are no redemption rights under Luxembourg law in connection with the Redomiciliation Transaction.

Statutory Appraisal Rights under Luxembourg Law

There are no statutory appraisal rights under Luxembourg law in connection with the Redomiciliation Transaction.

Anticipated Accounting Treatment

There will be no accounting effect or change in the carrying amount of the consolidated assets and liabilities of Perimeter Luxembourg as a result of domestication. The business, capitalization, assets and liabilities, and financial statements of Perimeter Delaware immediately following the Redomiciliation Transaction will be substantially the same as those of Perimeter Luxembourg immediately prior to such transaction, subject to certain subsidiary restructuring transactions to occur within our corporate group in connection with the domestication.

Regulatory Matters

Other than the Delaware Filings and the adoption of the subsequent shareholders’ resolutions before a notary in the Grand Duchy of Luxembourg confirming that all conditions to the Redomiciliation Transaction have been satisfied or waived and that the Redomiciliation Transaction is effective, we are not aware of any governmental approvals or actions that are required to complete the Redomiciliation Transaction other than compliance with U.S. federal and state securities laws, and various portions of Luxembourg Company Law. It is presently contemplated that if any such additional regulatory approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.

Recommendation and Required Vote

After completing its review of the expected benefits and the potential advantages of the Redomiciliation Transaction, on July 10, 2024, the Perimeter Luxembourg Board unanimously approved the Redomiciliation Transaction and resolved to recommend adoption of the Redomiciliation Proposal to Existing Shareholders. The Perimeter Luxembourg Board recommends that you vote “FOR” the Redomiciliation Proposal to be presented at the Special Meeting.

61

Pursuant to the Existing Articles and in accordance with Luxembourg Company Law, the Redomiciliation Proposal must be effected by the affirmative vote of at least two-thirds of the votes validly cast at the Special Meeting, provided that at least one half of the issued shares of Perimeter Luxembourg to which voting rights are attached pursuant to the Existing Articles or Luxembourg Company Law is present or represented at the Special Meeting. Existing Ordinary Shareholders and Existing Preferred Shareholder, voting as separate classes, are entitled to vote on the Redomiciliation Proposal.

62

THE ORGANIZATIONAL DOCUMENTS PROPOSAL

Overview

If the Redomiciliation Proposal is approved and the domestication is to be effected, Perimeter Luxembourg will replace its Existing Articles under the Luxembourg Company Law with the Proposed Organizational Documents under the DGCL. After the Redomiciliation Transaction, your rights under the DGCL as a holder of Common Stock or Preferred Stock, as applicable, will differ from your current rights under the Luxembourg Company Law as a holder of Existing Ordinary Shares or Existing Preferred Shares, respectively. In addition, the Proposed Charter and the Proposed Bylaws differ in some respects from the Existing Articles, as further described in “Comparison of Shareholder Rights Between Luxembourg Law and Delaware Law.”

Perimeter Luxembourg is proposing the adoption of the Proposed Organizational Documents in connection with the Redomiciliation Transaction because they contain provisions typical of other Delaware corporations. The Organizational Documents Proposal is conditioned on the approval of the Redomiciliation Proposal. Therefore, if the Redomiciliation Proposal is not approved, the Organizational Documents Proposal will have no effect, even if approved by our Existing Shareholders. A brief summary of the Organizational Documents Proposal is set forth below, which summaries are qualified in their entirety by reference to the complete text of the Proposed Organizational Documents included elsewhere in this Proxy/Prospectus.

Existing Shareholders are being asked to consider and vote upon a proposal to approve by special resolution, assuming the Redomiciliation Proposal is approved and adopted, the replacement of the Existing Articles with the Proposed Charter on the effective date of the Redomiciliation Transaction, including, among other things, adopting Delaware as the exclusive forum for certain stockholder litigation.

Comparison of Rights of Holders of Existing Shares with Holders of Common Stock or Preferred Stock

The completion of the Redomiciliation Transaction will change the governing corporate law that applies to shareholders of Perimeter Delaware from Luxembourg law to Delaware law. The legal system governing corporations organized under Delaware law differs from the legal system governing corporations organized under Luxembourg law. As a result, while we have attempted maintain the substantive provisions of our Existing Articles, particularly as they pertain to shareholder rights, we are unable to adopt governing documents for Perimeter Delaware that are identical to the governing documents for Perimeter Luxembourg. We summarize the material differences between the Existing Articles and the Proposed Organizational Documents, and the changes in your rights as a shareholder resulting from the Redomiciliation Transaction, under “Comparison of Shareholder Rights Between Luxembourg Law and Delaware Law.” We believe that these changes (i) either are required by Delaware law or otherwise result from differences between the corporate laws of the Grand Duchy of Luxembourg and the corporate laws of Delaware, and (ii) relate to the change of the place of incorporation of Perimeter Luxembourg from the Grand Duchy of Luxembourg to Delaware. Forms of the Proposed Charter and Proposed Bylaws that will be effective upon completion of the Redomiciliation Transaction are attached as Annexes A and B, respectively, to this Proxy/Prospectus.

Notwithstanding the differences in the governing documents between Perimeter Luxembourg and Perimeter Delaware, we believe that Delaware law and the Proposed Organizational Documents as a whole adequately safeguard the rights of shareholders of Perimeter Luxembourg.

The characteristics of, and the differences between, the Existing Shares and the Common Stock or Preferred Stock are summarized under “Description of Perimeter Delaware Securities” and “Comparison of Shareholder Rights Between Luxembourg Law and Delaware Law.”

Recommendation and Required Vote

The Perimeter Luxembourg Board recommends that you vote “FOR” the Organizational Documents Proposal to be presented at the Special Meeting.

63

Pursuant to the Existing Articles and in accordance with Luxembourg Company Law, the Organizational Documents Proposal must be effected by the affirmative vote of at least two-thirds of the votes validly cast at the Special Meeting, provided that at least one half of the issued shares of Perimeter Luxembourg to which voting rights are attached pursuant to the Existing Articles or Luxembourg Company Law is present or represented at the Special Meeting. Existing Ordinary Shareholders and Existing Preferred Shareholder, voting as separate classes, are entitled to vote on the Organizational Documents Proposal.

64

THE DELEGATION OF AUTHORITY PROPOSAL

Overview

In accordance with Luxembourg law, Existing Ordinary Shareholders are being asked to grant power and authority to any director of Perimeter Luxembourg and/or any lawyer or employee of the law firm Maples and Calder (Luxembourg) SARL and/or any employee or clerk of the instrumenting notary in the Grand Duchy of Luxembourg, to individually carry out, with full power of substitution and sub-delegation, in the name and on behalf of Perimeter Luxembourg, any changes required by the matters set out under the proposals described in this Proxy/Prospectus as well as all filings, notifications and publications necessary for the Redomiciliation Transaction.

The Delegation of Authority Proposal is conditioned on the approval of the Redomiciliation Proposal. Therefore, if the Redomiciliation Proposal is not approved, the Delegation of Authority Proposal will have no effect, even if approved by our Existing Ordinary Shareholders.

Recommendation and Required Vote

The Perimeter Luxembourg Board recommends that you vote “FOR” the Delegation of Authority Proposal to be presented at the Special Meeting.

Pursuant to the Existing Articles and in accordance with Luxembourg Company Law, the Delegation of Authority Proposal must be effected by the affirmative vote of at least one half of the votes validly cast at the Special Meeting, provided that at least one half of the issued shares of Perimeter Luxembourg to which voting rights are attached pursuant to the Existing Articles or Luxembourg Company Law is present or represented at the Special Meeting. Only Existing Ordinary Shareholders are required to vote on the Delegation of Authority Proposal.

Segments

Our business is organized and managed in two reporting segments: Fire Safety and Specialty Products.

Fire Safety Segment

The Fire Safety segment provides fire retardants and firefighting foams, as well as specialized equipment and services typically offered in conjunction with our retardant and foam products.

Fire Retardants

Our fire retardants help slow, stop and prevent wildfires by chemically altering fuels (e.g., vegetation) and rendering them non-flammable. Fire retardant is typically applied ahead of an active wildland fire to stop or slow its spread, in order to allow ground-based firefighters to safely extinguish the fire. Retardants can be applied aerially via fixed or rotor wing aircraft, or by ground using standard fire engines or our dedicated ground-applied retardant units. All of our products have a high level of retardant effectiveness, and differences in visibility, viscosity, adherence to vegetation, and persistence through weathering.

Our fire retardant customers are typically government agencies with responsibility for protecting both government and private land, although we also serve commercial customers. We supply federal, state, provincial,

66

local/municipal, and commercial customers around the world, including in the United States, Canada, France, Spain, Italy, Chile, Australia and Israel. We are a supplier of USDA Forest Service qualified fire retardant – a standard that many countries have adopted for ensuring fire retardant is effective, safe and environmentally friendly.

While fire retardant is primarily used to stop or slow the spread of active wildland fires, our fire retardant is also increasingly utilized in a preventative capacity. We are expanding our offerings to several high hazard industries. Wildfires ignited by utilities have turned into some of the most devastating wildfires in U.S. history, many of which have occurred in recent years. Western U.S. states in particular are becoming increasingly diligent in wildfire prevention efforts and increasing their investments to prevent wildfire risk.

We are focused on being an innovation leader in fire retardant, driving continuous improvements in product performance to offer increasing value for our customers. We have made significant enhancements in safety, environmental stewardship and effectiveness, as well as advancements in visibility and aerial drop performance. Working in partnership with the USDA Forest Service wildland fire chemicals group to characterize and develop new products, we consistently release new standard-setting products, including the Phos-Chek^® “Fx” family of ultra-high visibility fugitive-colored products, Phos-Chek LCE20-Fx next generation liquid concentrate, which combines high performance with improved environmental performance, and Phos-Chek Fortify^® durable retardant, which can offer long-term protection until a significant rainfall event.

Firefighting Foams

We offer a comprehensive and effective line of firefighting foam, including Class A, Class B, Class A/B, and training foams.

Class A foam is primarily used to combat structural fires and wildfires. Class A foam is specially formulated to make water more effective for structural fire suppression. The surfactants in Class A foam significantly reduce water’s surface tension, and, when mixed with air, create a foam blanket that surrounds fuels. The foam blanket creates a barrier between the fuel and the fire, knocking down the fire faster than water alone, and allowing fire fighters to see the areas of application. Utilizing Class A foam reduces the amount of water needed to extinguish the fire, reduces water damage, and increases firefighter safety through quicker knockdown and reduced mop-up/overhaul requirements. Our Class A foam products are used by wildland firefighters to suppress wildland fires and are typically applied from various fixed wing air tankers, helicopters equipped with fixed tanks or buckets, standard fire engines or rapid attack brush trucks, or 5-gallon backpacks. In addition to wildfire suppression, Class A foam products are used by municipal and rural fire departments as a water enhancer to combat structural and other fires.

Class B foam is primarily used to combat flammable and combustible liquids. Fires caused by flammable and combustible liquids require foams designed for rapid extinguishment and a secure foam blanket to prevent reignition. The foam blanket must have good burn back resistance and strong integrity to minimize the spread of the fire from areas where the blanket has been compromised, for example by falling debris or the dragging of a fire hose or other equipment through the foam blanket. Our Class B foam products are primarily used by industrial customers with significant amounts of flammable and combustible liquids on-site, including petrochemical facilities, airports and other aviation and aerospace facilities, various military and defense facilities, and other industrial and commercial facilities.

Class A/B foam is a foam listed to fight both Class A (structural) fires and Class B (flammable liquid) fires. Our Class A/B foam products are primarily used by municipal fire departments. Training foam has similar characteristics to Class A and B foams but does not include active ingredients and has a shorter drain time so successive tests can be run without waiting for the foam to disappear. Training foam is used for training and exhibition purposes as well as in the evaluation of foam equipment.

67

We believe that we are an innovation leader in foams. Our Class B foams either use only C6 fluorosurfactant or are fluorine free. We offer several ground-breaking fluorine free firefighting foam formulations to aid the industry transition to reduce or eliminate the use of firefighting foams that contain Per- and polyfluoroalkyl substances (“PFAS”) in favor of fluorine-free foams. Our products are “ahead of the curve” on many fronts – including fire control performance, reduced viscosity, drainage time and higher stability.

Customer Equipment and Services

We offer a broad range of equipment and services to support live firefighting operations within our retardant and foam business lines. Our equipment and services are typically purchased and utilized in conjunction with our retardant or foam products and are often priced in a single bundle along with these products.

Custom equipment includes specialized air base retardant storage, mixing, and delivery equipment; mobile retardant bases; retardant ground application units; and mobile foam equipment. We also have the capability to design and manufacture highly custom equipment that operates at very high throughput and reliability levels, including equipment used to support emergency air tanker base and ground crew operations, as well as custom fire suppressant systems for stationary or portable operations typically used at industrial locations or for supporting municipality firefighting capabilities.

Custom services include design, construction, and installation of specialized air base retardant equipment, management and staffing of air base retardant operations, and management of air base supply and replenishment services. We have a broad service capability footprint, with full-service operations in over 50 United States and Canadian air bases, and equipment at over 100 bases globally.

Specialty Products Segment

The Specialty Products segment produces and sells P2S5 used in several end markets and applications, including lubricant additives, various agricultural applications, various mining applications, and emerging electric battery technologies. Within the lubricant additive end market, currently our largest end market application, P2S5 is primarily used in the production of a family of compounds called ZDDP, which is considered an essential component in the formulation of lubricating oils with its main function to provide anti-wear protection to engine components. In addition, ZDDP inhibits oxidation of lubricating oil by scavenging free radicals that initiate oil breakdown and sludge formation, resulting in better and longer engine function. P2S5 is also used in pesticide and mining chemicals applications. We offer several grades of P2S5 with varying degrees of phosphorus content, particle size, distribution, and reactivity to global customers. The P2S5 production process requires a high degree of technical expertise given the reactivity and need for safe transportation and handling. We are committed to being a technology and safety leader, with strong product stewardship and a strong safety track-record. We also conduct regular customer visits and provide extensive technical training to ensure customers are committed to operating safely.

We are focused on being an innovation leader in the specialty products market. Most recently, we engineered and patented superior storage and handling equipment to safely and efficiently handle and transport P2S5 with lower cost and maintenance requirements.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion is a summary of certain material U.S. federal income tax considerations (i) for U.S. Holders and Non-U.S. Holders (each as defined below, and together, “Holders”) of Existing Ordinary Shares and Existing Preferred Shares (each, a “Perimeter Luxembourg Stock”) of the Redomiciliation Transaction and (ii) for Non-U.S. Holders of the ownership and disposition of shares of Common Stock and Preferred Stock (each, a “Perimeter Delaware Stock”) received in the Redomiciliation Transaction. This section applies only to Holders that hold their Perimeter Luxembourg Stock and Perimeter Delaware Stock as “capital assets” for U.S. federal income tax purposes (generally, property held for investment).

This discussion is limited to U.S. federal income tax considerations and does not address estate or any gift tax considerations or considerations arising under the tax laws of any state, local or non-U.S. jurisdiction. This discussion does not describe all of the U.S. federal income tax consequences that may be relevant to you in light of your particular circumstances, including the alternative minimum tax, the Medicare tax on certain investment income and the different consequences that may apply if you are subject to special rules under U.S. federal income tax law that apply to certain types of investors, such as:

If a partnership (or any entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds Perimeter Luxembourg Stock, the tax treatment of such partnership and a person treated as a partner of such partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships holding any Perimeter Luxembourg Stock and persons that are treated as partners of such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences to them of the Redomiciliation Transaction and the ownership and disposition of Perimeter Delaware Stock received in the Redomiciliation Transaction.

71

This discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), proposed, temporary and final Treasury Regulations promulgated thereunder, and judicial and administrative interpretations thereof, all as of the date hereof. All of the foregoing is subject to change, which change could apply retroactively and could affect the tax considerations described herein.

The following discussion discusses solely the consequences of the Redomiciliation Transaction and does not discuss any other steps that may be taken by Perimeter Luxembourg or Perimeter Delaware in connection with the Redomiciliation Transaction.

We have not sought, and do not intend to, seek any rulings from the Internal Revenue Service (the “IRS”) as to any U.S. federal income tax considerations described herein. There can be no assurance that the IRS will not take positions inconsistent with the considerations discussed below or that any such positions would not be sustained by a court.

THIS DISCUSSION IS ONLY A SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS ASSOCIATED WITH THE REDOMICILIATION TRANSACTION AND THE OWNERSHIP AND DISPOSITION OF PERIMETER DELAWARE STOCK RECEIVED IN THE REDOMICILIATION. EACH HOLDER SHOULD CONSULT ITS OWN TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH HOLDER OF THE REDOMICILIATION TRANSACTION AND THE OWNERSHIP AND DISPOSITION OF PERIMETER DELAWARE STOCK RECEIVED IN THE REDOMICILIATION, INCLUDING THE APPLICABILITY AND EFFECTS OF U.S. FEDERAL NON-INCOME, STATE AND LOCAL AND NON-U.S. TAX LAWS.

U.S. HOLDERS

As used herein, a “U.S. Holder” is a beneficial owner of a Perimeter Luxembourg Stock who or that is, for U.S. federal income tax purposes:

Tax Effects of the Redomiciliation Transaction to U.S. Holders

Generally

The U.S. federal income tax consequences of the Redomiciliation Transaction will depend primarily upon whether the Redomiciliation Transaction qualifies as a “reorganization” within the meaning of Section 368 of the Code.

Under Section 368(a)(1)(F) of the Code, a reorganization is a “mere change in identity, form, or place of organization of one corporation, however effected” (an “F Reorganization”). Pursuant to the Redomiciliation Transaction, Perimeter Luxembourg will change its jurisdiction of incorporation from the Grand Duchy of Luxembourg to the State of Delaware, upon which Perimeter Luxembourg will continue as an entity under the name “Perimeter Solutions, Inc.” (the “Name Change”).

72

It is intended that the Redomiciliation Transaction qualify as an F Reorganization. However, Perimeter Luxembourg has not sought, and does not intend to seek, any ruling from the IRS with respect to the qualification of the Redomiciliation Transaction as an F Reorganization, and the closing of the Redomiciliation Transaction is not conditioned on the receipt of any ruling from the IRS or any opinion of counsel with respect to the qualification of the Redomiciliation Transaction as an F Reorganization. Consequently, no assurance can be given that the IRS will not assert, or that a court would not sustain, a position contrary to any of those set forth below. Accordingly, each U.S. Holder of Perimeter Luxembourg Stock is urged to consult its tax advisor with respect to the particular tax consequence of the Redomiciliation Transaction to such U.S. Holder.

Assuming the Redomiciliation Transaction qualifies as an F Reorganization, U.S. Holders of Perimeter Luxembourg Stock generally should not recognize gain or loss for U.S. federal income tax purposes on the Redomiciliation Transaction, except as provided below under the sections entitled “—Effects of Section 367 to U.S. Holders of Existing Ordinary Shares and Existing Preferred Shares” and “—PFIC Considerations,” and the Redomiciliation Transaction should be treated for U.S. federal income tax purposes as if Perimeter Luxembourg (i) transferred all of its assets and liabilities to Perimeter Delaware in exchange for all of the outstanding Perimeter Delaware Stock; and (ii) then distributed the Perimeter Delaware Stock to the holders of Perimeter Luxembourg Stock in liquidation of Perimeter Luxembourg. The taxable year of Perimeter Luxembourg will be deemed to end on the date of the Redomiciliation Transaction.

Subject to the discussion below under the section entitled “—PFIC Considerations,” if the Redomiciliation Transaction fails to qualify as an F Reorganization, a U.S. Holder of Perimeter Luxembourg Stock generally would recognize gain or loss with respect to its Perimeter Luxembourg Stock in an amount equal to the difference, if any, between the fair market value of the corresponding Perimeter Delaware Stock received in the Redomiciliation Transaction and the U.S. Holder’s adjusted tax basis in its Perimeter Luxembourg Stock surrendered.

Following the Redomiciliation Transaction, a U.S. Holder generally would be required to include in gross income as U.S. source dividend income the amount of any distribution of cash or other property paid or deemed paid on the Perimeter Delaware Stock to the extent the distribution is paid out of Perimeter Delaware’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Dividends received by a U.S. Holder that is treated as a corporation for U.S. federal income tax purposes generally will qualify for a dividends received deduction if the requisite holding period is satisfied. With certain exceptions, and provided certain holding period requirements are met, dividends received by a non-corporate U.S. Holder will generally constitute “qualified dividends” that will be subject to U.S. federal income tax at preferential long-term capital gains rates. U.S. Holders are urged to consult with their tax advisors regarding this and any other tax considerations of owning common and preferred stock of a U.S. corporation, i.e., Perimeter Delaware, rather than a non-U.S. corporation following the Redomiciliation Transaction.

The Name Change is not expected to have any U.S. federal income tax consequences to U.S. Holders.

Basis and Holding Period Considerations

Assuming the Redomiciliation Transaction qualifies as an F Reorganization, subject to the discussion below under the section entitled “—PFIC Considerations”:

73

If the Redomiciliation Transaction fails to qualify as an F Reorganization, the U.S. Holder’s basis in a Perimeter Delaware Stock would be equal to the fair market value of such Perimeter Delaware Stock on the date of the Redomiciliation Transaction, and such U.S. Holder’s holding period for the such Perimeter Delaware Stock would begin on the day following the date of the Redomiciliation Transaction. U.S. Holders who hold different blocks of Perimeter Luxembourg Stock (generally, Perimeter Luxembourg Stock purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them, and the discussion above does not specifically address all of the consequences to U.S. Holders who hold different blocks of Perimeter Luxembourg Stock.

Effects of Section 367 to U.S. Holders of Existing Ordinary Shares and Existing Preferred Shares

Section 367 of the Code applies to certain transactions involving foreign corporations, including a redomiciliation of a foreign corporation in a transaction that qualifies as an F Reorganization. Subject to the discussion below under the section entitled “— PFIC Considerations,” Section 367 of the Code imposes U.S. federal income tax on certain U.S. persons in connection with transactions that would otherwise be tax-deferred. Section 367(b) of the Code will generally apply to U.S. Holders on the date of the Redomiciliation Transaction.

U.S. Holders Who Own 10 Percent or More (By Vote or Value) of Perimeter Luxembourg Stock

Subject to the discussion below under the section entitled “— PFIC Considerations,” a U.S. Holder who beneficially owns (actually or constructively) 10% or more of the total combined voting power of all classes of Perimeter Luxembourg stock entitled to vote or 10% or more of the total value of all classes of Perimeter Luxembourg stock (a “10% U.S. Shareholder”) on the date of the Redomiciliation Transaction generally must include in income as a deemed dividend paid by Perimeter Luxembourg the “all earnings and profits amount” attributable to the Existing Ordinary Shares and Existing Preferred Shares (“Existing Shares”) it owns within the meaning of Treasury Regulations under Section 367 of the Code. A U.S. Holder’s ownership of any warrants or options with respect to Perimeter Luxembourg Stock will be taken into account in determining whether such U.S. Holder is a 10% U.S. Shareholder. Complex attribution rules apply in determining whether a U.S. Holder is a 10% U.S. Shareholder, and all U.S. Holders are urged to consult their tax advisors with respect to these attribution rules.

A 10% U.S. Shareholder’s “all earnings and profits amount” with respect to its Existing Shares is the net positive earnings and profits of Perimeter Luxembourg (as determined under Treasury Regulations under Section 367 of the Code) attributable to such Existing Shares (as determined under Treasury Regulations under Section 367 of the Code). Treasury Regulations under Section 367 of the Code provide that the “all earnings and profits amount” attributable to a shareholder’s stock is determined according to the principles of Section 1248 of the Code. In general, Section 1248 of the Code and the Treasury Regulations thereunder provide that the amount of earnings and profits attributable to a block of stock (as defined in Treasury Regulations under Section 1248 of the Code) in a foreign corporation is the ratably allocated portion of the foreign corporation’s earnings and profits generated during the period the shareholder held the block of stock.

Perimeter Luxembourg expects to have a deficit in earnings and profits on the date of the Redomiciliation Transaction. If Perimeter Luxembourg’s cumulative net earnings and profits through the date of the Redomiciliation Transaction is less than or equal to zero, then a 10% U.S. Shareholder should not be required to include in gross income an “all earnings and profits amount” with respect to its Existing Shares. However, it is possible that, notwithstanding Perimeter Luxembourg’s expectations, the amount of Perimeter Luxembourg’s cumulative net earnings and profits could be positive through the date of the Redomiciliation Transaction, in which case a 10% U.S. Shareholder would be required to include its “all earnings and profits amount” in income as a deemed dividend paid by Perimeter Luxembourg under Treasury Regulations under Section 367 as a result of the Redomiciliation Transaction. Therefore, there can be no assurance that Perimeter Luxembourg will indeed have a deficit in earnings and profits on the date of the Redomiciliation Transaction.

74

U.S. Holders Who Own Less Than 10% (By Vote or Value) of Perimeter Luxembourg Stock

Subject to the discussion below under the section entitled “— PFIC Considerations,” a U.S. Holder whose Existing Shares, on the date of the Redomiciliation Transaction, have a fair market value of $50,000 or more and who, on the date of the Redomiciliation Transaction, is not a 10% U.S. Shareholder generally will recognize gain (but not loss) with respect to its Existing Shares in the Redomiciliation Transaction or, in the alternative, may elect to recognize the “all earnings and profits” amount attributable to such U.S. Holder’s Existing Shares as described below.

Subject to the discussion below under the section entitled “— PFIC Considerations,” unless a U.S. Holder makes the “all earnings and profits election” as described below, such U.S. Holder generally must recognize gain (but not loss) with respect to the shares of Common Stock and Preferred Stock (“Perimeter Delaware Stock”) received in the Redomiciliation Transaction in an amount equal to the excess of the fair market value of such shares of Perimeter Delaware Stock over the U.S. Holder’s adjusted tax basis in the Existing Shares deemed surrendered in exchange therefor. U.S. Holders who hold different blocks of Existing Shares (generally, Existing Shares purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them.

In lieu of recognizing any gain as described in the preceding paragraph, a U.S. Holder may elect to include in income as a deemed dividend paid by Perimeter Luxembourg the “all earnings and profits amount” attributable to its Existing Shares under Section 367(b) of the Code. There are, however, strict conditions for making this election. This election must comply with applicable Treasury Regulations and generally must include, among other things:

In addition, the election must be attached by an electing U.S. Holder to such U.S. Holder’s timely filed U.S. federal income tax return for the year of the Redomiciliation Transaction, and the U.S. Holder must send notice of making the election to Perimeter Luxembourg or Perimeter Delaware no later than the date such tax return is filed. In connection with this election, Perimeter Luxembourg may in its discretion provide each U.S. Holder eligible to make such an election with information regarding Perimeter Luxembourg’s earnings and profits upon written request.

Perimeter Luxembourg expects to have a deficit in earnings and profits through the date of the Redomiciliation Transaction and if that proves to be the case, U.S. Holders who make this election are not expected to have any income inclusion under Section 367(b) of the Code, provided that the U.S. Holder properly executes the election and complies with the applicable notice requirements. However, as noted above, if it were

75

ultimately determined that Perimeter Luxembourg had positive earnings and profits through the date of the Redomiciliation Transaction, a U.S. Holder that makes the election described herein could have an “all earnings and profits amount” with respect to its Existing Shares, and thus could be required to include that amount in income as a deemed dividend paid by Perimeter Luxembourg under applicable Treasury Regulations as a result of the Redomiciliation Transaction.

A U.S. Holder who is not a 10% U.S. Shareholder on the date of the Redomiciliation Transaction and whose Existing Shares have a fair market value of less than $50,000 on the date of the Redomiciliation Transaction generally should not be required to recognize any gain or loss or include any part of the “all earnings and profits amount” in income under Section 367 of the Code in connection with the Redomiciliation Transaction. However, such U.S. Holder may be subject to taxation under the PFIC rules as discussed below under the section entitled “— PFIC Considerations.”

EACH U.S. HOLDER IS URGED TO CONSULT ITS TAX ADVISOR REGARDING THE CONSEQUENCES TO IT OF THE REDOMICILIATION TRANSACTION INCLUDING THE MAKING AN ELECTION TO INCLUDE IN INCOME THE “ALL EARNINGS AND PROFITS AMOUNT” ATTRIBUTABLE TO ITS EXISTING SHARES UNDER SECTION 367(b) OF THE CODE AND THE APPROPRIATE FILING REQUIREMENTS WITH RESPECT TO SUCH AN ELECTION.

ALL U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE EFFECT OF SECTION 367 OF THE CODE TO THEIR PARTICULAR CIRCUMSTANCES.

PFIC Considerations

Regardless of whether the Redomiciliation Transaction qualifies as an F Reorganization (and, if the Redomiciliation Transaction qualifies as an F Reorganization, in addition to the discussion under the section entitled “— Effects of Section 367 to U.S. Holders of Existing Ordinary Shares and Existing Preferred Shares” above), the Redomiciliation Transaction could be a taxable event to U.S. Holders under the PFIC provisions of the Code if Perimeter Luxembourg is considered a PFIC.

Definition of a PFIC

A foreign (i.e., non-U.S.) corporation will be classified as a PFIC for U.S. federal income tax purposes if either (i) at least 75% of its gross income in a taxable year, including its pro rata share of the gross income of any corporation in which it is considered to own at least 25% of the shares by value, is passive income or (ii) at least 50% of its assets in a taxable year (generally determined based on fair market value and averaged quarterly over the year), including its pro rata share of the assets of any corporation in which it is considered to own at least 25% of the shares by value, are held for the production of, or produce, passive income. Passive income generally includes dividends, interest, rents and royalties (other than rents or royalties derived from the active conduct of a trade or business received from unrelated persons) and gains from the disposition of passive assets. The determination of whether a foreign corporation is a PFIC is made annually. Pursuant to a “startup exception,” a foreign corporation will not be a PFIC for the first taxable year the foreign corporation has gross income (the “startup year”) if (1) no predecessor of the foreign corporation was a PFIC; (2) the foreign corporation satisfies the IRS that it will not be a PFIC for either of the first two taxable years following the startup year; and (3) the foreign corporation is not in fact a PFIC for either of those years.

PFIC Status of Perimeter Luxembourg

Based upon the composition of its income and assets and the manner in which it operates its business, Perimeter Luxembourg believes it was not a PFIC for its most recent taxable year ended on December 31, 2023 and for the taxable year which ends as a result of the Redomiciliation Transaction. Due to the factual nature of the determination, no assurance can be given as to whether Perimeter Luxembourg would be or would not be a PFIC for any taxable year.

76

Effects of PFIC Rules on the Redomiciliation Transaction

Even if the Redomiciliation Transaction qualifies as an F Reorganization, Section 1291(f) of the Code requires that, to the extent provided in Treasury Regulations, a U.S. person who disposes of stock of a PFIC (which, under proposed Treasury Regulations may include a U.S. person exchanging warrants of a PFIC for newly issued warrants in connection with a redomiciliation transaction) recognizes gain notwithstanding any other provision of the Code. No final Treasury Regulations are currently in effect under Section 1291(f) of the Code. However, proposed Treasury Regulations under Section 1291(f) of the Code have been promulgated with a retroactive effective date. If finalized in their current form, those proposed Treasury Regulations would require gain recognition to U.S. Holders of Perimeter Luxembourg Stock as a result of the Redomiciliation Transaction if:

The tax on any such recognized gain would be imposed based on a complex set of computational rules designed to offset the tax deferral with respect to the undistributed earnings of Perimeter Luxembourg. Under these rules:

In addition, the proposed Treasury Regulations provide coordinating rules with Section 367(b) of the Code, whereby, if the gain recognition rule of the proposed Treasury Regulations discussed in the preceding paragraph applies to a disposition of PFIC stock that results from a transfer with respect to which Section 367(b) of the Code requires the U.S. Holder to recognize gain or include an amount in income as a deemed dividend deemed paid by Perimeter Luxembourg, the gain realized on the transfer is taxable under the rules described in the preceding paragraph, and the excess, if any, of the amount to be included in income under Section 367(b) of the Code over the gain realized is taxable as provided under Section 367(b) of the Code. See the discussion above under the section entitled “— Effects of Section 367 to U.S. Holders of Existing Ordinary Shares and Existing Preferred Shares.”

It is difficult to predict whether, in what form and with what effective date, final Treasury Regulations under Section 1291(f) of the Code may be adopted or how any such final Treasury Regulations would apply. If the

77

proposed regulations under Section 1291(f) were finalized in the current form, U.S. Holders of Existing Shares that have not made a timely and effective QEF Election (or a QEF Election along with a purging election) or a MTM Election (each as defined below) (a “Non-Electing Shareholder”) may be subject to taxation under the PFIC rules on the Redomiciliation Transaction with respect to their Perimeter Luxembourg Stock in the manner set forth above.

Any gain recognized by a Non-Electing Shareholder of Existing Shares as a result of the Redomiciliation Transaction pursuant to PFIC rules would be taxable income to such U.S. Holder, taxed under the PFIC rules in the manner set forth above, with no corresponding receipt of cash.

As noted above, absent a QEF Election (or a QEF Election along with a purging election) or a MTM Election, the Redomiciliation Transaction could be a taxable event under the PFIC rules regardless of whether the Redomiciliation Transaction qualifies as an F Reorganization if Perimeter Luxembourg is considered a PFIC. If the Redomiciliation Transaction fails to qualify as an F Reorganization, absent a QEF Election (or a QEF Election along with a purging election) or a MTM Election, a U.S. Holder’s gain, if any, would be taxed under the PFIC rules in the manner set forth above.

ALL U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE EFFECTS OF THE PFIC RULES ON THE REDOMICILIATION TRANSACTION, INCLUDING THE IMPACT OF ANY PROPOSED OR FINAL TREASURY REGULATIONS.

QEF Election and Mark-to-Market Election

The impact of the PFIC rules on a U.S. Holder of Existing Shares will depend on whether the U.S. Holder has made a timely and effective election to treat Perimeter Luxembourg as a “qualified electing fund” under Section 1295 of the Code for the taxable year that is the first year in the U.S. Holder’s holding period of Existing Shares during which Perimeter Luxembourg qualified as a PFIC (a “QEF Election”) or, if in a later taxable year, the U.S. Holder made a QEF Election along with a purging election. A purging election creates a deemed sale of the U.S. Holder’s Existing Shares at their then fair market value and requires the U.S. Holder to recognize gain pursuant to the purging election subject to the special PFIC tax and interest charge rules described above. As a result of any such purging election, the U.S. Holder would increase the adjusted tax basis in its Existing Shares by the amount of the gain recognized and, solely for purposes of the PFIC rules, would have a new holding period in its Existing Shares. U.S. Holders are urged to consult their tax advisors as to the application of the rules governing purging elections to their particular circumstances.

A U.S. Holder that made a timely and effective QEF Election (or a QEF Election along with a purging election) or a MTM Election (an “Electing Shareholder”) generally would not be subject to the adverse PFIC rules discussed above with respect to its Existing Shares. As a result, such an Electing Shareholder generally should not recognize gain or loss as a result of the Redomiciliation Transaction except to the extent described under “— Effects of Section 367 to U.S. Holders of Existing Ordinary Shares and Existing Preferred Shares” and subject to the discussion above under “— Tax Effects of the Redomiciliation Transaction to U.S. Holders.” If an Electing Shareholder has made a QEF Election, it would instead include annually in gross income its pro rata share of the ordinary earnings and net capital gain of Perimeter Luxembourg, whether or not such amounts are actually distributed.

The impact of the PFIC rules on a U.S. Holder of Existing Shares may also depend on whether the U.S. Holder has made a mark-to-market election under Section 1296 of the Code. U.S. Holders who hold (actually or constructively) stock of a foreign corporation that is classified as a PFIC may annually elect to mark such stock to its market value if such stock is “marketable stock,” generally, stock that is regularly traded on a national securities exchange that is registered with the SEC, including Nasdaq (a “MTM Election”). No assurance can be given that the Existing Shares are considered to be marketable stock for purposes of the MTM Election or whether the other requirements of this election are satisfied. If such an election is available and has

78

been made, such U.S. Holders generally will not be subject to the special taxation rules of Section 1291 of the Code discussed herein with respect to their Existing Shares in connection with the Redomiciliation Transaction or otherwise. Instead, in general, the U.S. Holder will include as ordinary income each year the excess, if any, of the fair market value of its Existing Shares at the end of its taxable year over its adjusted basis in its Existing Shares. The U.S. Holder also will recognize an ordinary loss in respect of the excess, if any, of its adjusted basis in its Existing Shares over the fair market value of its Existing Shares at the end of its taxable year (but only to the extent of the net amount of previously included income as a result of the MTM Election). The U.S. Holder’s basis in its Existing Shares will be adjusted to reflect any such income or loss amounts, and any further gain recognized on a sale or other taxable disposition of its Existing Shares will be treated as ordinary income. However, if the MTM Election is not made by a U.S. Holder with respect to the first taxable year of its holding period for the PFIC stock, then the Section 1291 rules discussed above will apply to certain dispositions of, distributions on and other amounts taxable with respect to Existing Shares, including in connection with the Redomiciliation Transaction.

THE RULES DEALING WITH PFICS ARE VERY COMPLEX AND ARE IMPACTED BY VARIOUS FACTORS IN ADDITION TO THOSE DESCRIBED ABOVE, INCLUDING THE APPLICATION OF THE RULES ADDRESSING OVERLAPS IN THE PFIC RULES AND THE SECTION 367(b) RULES AND THE RULES RELATING TO CONTROLLED FOREIGN CORPORATIONS. ALL U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE CONSEQUENCES TO THEM OF THE PFIC RULES, INCLUDING, WITHOUT LIMITATION, WHETHER A QEF ELECTION (OR A QEF ELECTION ALONG WITH A PURGING ELECTION), A MTM ELECTION OR ANY OTHER ELECTION IS AVAILABLE AND WHETHER AND HOW ANY OVERLAP RULES APPLY, AND THE CONSEQUENCES TO THEM OF ANY SUCH ELECTION OR OVERLAP RULE AND THE IMPACT OF ANY PROPOSED OR FINAL PFIC TREASURY REGULATIONS.

NON-U.S. HOLDERS

As used herein, a “Non-U.S. Holder” is a beneficial owner of a Perimeter Luxembourg Stock who or that is, for U.S. federal income tax purposes:

Effects of the Redomiciliation Transaction to Non-U.S. Holders

The Redomiciliation Transaction is not expected to result in any U.S. federal income tax consequences to Non-U.S. Holders of Perimeter Luxembourg Stock. In addition, the Name Change is not expected to have any U.S. federal income tax consequences to Non-U.S. Holders.

The following describes U.S. federal income tax considerations relating to the ownership and disposition of Perimeter Delaware Stock by a Non-U.S. Holder after the Redomiciliation Transaction.

Actual and Constructive Distributions on Perimeter Delaware Stock

In general, any distributions (including constructive distributions, but not including certain distributions of shares or rights to acquire Common Stock) made to a Non-U.S. Holder of Perimeter Delaware Stock, to the extent paid out of Perimeter Delaware’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles), will constitute U.S. source dividends for U.S. federal income tax purposes

79

and, provided such dividends are not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States, Perimeter Delaware or other applicable withholding agent will be required to withhold tax from the gross amount of the dividend at a rate of 30%, unless such Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on IRS Form W-8BEN or W-8BEN-E). Any distribution not constituting a dividend will be treated first as reducing (but not below zero) the Non-U.S. Holder’s adjusted tax basis in its shares of Common Stock and, to the extent such distribution exceeds the Non-U.S. Holder’s adjusted tax basis, as gain realized from the sale or other disposition of the Common Stock, which will be treated as described under “— Sale, Taxable Exchange or Other Taxable Disposition of Common Stock, Preferred Stock and Warrants” below.

Under the rules contained in Section 305(c) of the Code and Treasury Regulations promulgated thereunder (the “preferred stock distribution rules”), if the stated redemption price of the Preferred Stock (which generally means all amounts payable on the Preferred Stock, including any amount added to the liquidation preference when any preferential dividend on the Preferred Stock is paid in kind) exceeds its issue price by more than certain de minimis amount defined in Treasury Regulations and certain other conditions are met, a Non-U.S. Holder may be treated as receiving the difference (a “redemption premium”) over time as one or more constructive distributions from Perimeter Delaware. More specifically, if the preferred stock distribution rules apply, a Non-U.S. Holder of the Preferred Stock generally would be treated as receiving a constructive distribution from Perimeter Delaware with respect to the redemption premium on an annual basis under a constant-yield accrual method regardless of such Non-U.S. Holder’s regular method of tax accounting. As a result, such Non-U.S. Holder generally would be treated for U.S. federal income tax purposes as receiving such constructive distributions from Perimeter Delaware in advance of the receipt of the cash attributable to the redemption premium. Non-U.S. Holders are urged to consult their tax advisors regarding the potential application of the preferred stock distribution rules.

In the case of any constructive distribution that is treated as dividend as described above, it is possible that the withholding tax on dividends described above would be withheld from any amount owed to a Non-U.S. Holder by the applicable withholding agent, including cash distributions on other property or sale or redemption proceeds from Perimeter Delaware Stock or warrants or other property subsequently paid or credited to such Non-U.S. Holder. The withholding tax described above generally does not apply to dividends paid to a Non-U.S. Holder who provides a completed IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States. Instead, such effectively connected dividends will be subject to regular U.S. federal income tax as if the Non-U.S. Holder were a U.S. resident, subject to an applicable income tax treaty providing otherwise. A corporate Non-U.S. Holder receiving effectively connected dividends may also be subject to an additional “branch profits tax” imposed at a rate of 30% (or a lower applicable treaty rate).

Sale, Taxable Exchange or Other Taxable Disposition of Perimeter Delaware Stock

Subject to the discussion below under “—Redemption of Preferred Stock by Perimeter Delaware”, a Non-U.S. Holder generally will not be subject to U.S. federal income tax (including withholding of U.S. federal income tax) in respect of gain recognized on a sale, taxable exchange or other taxable disposition of its Common Stock or Preferred Stock, unless:

80

Unless an applicable treaty provides otherwise, gain described in the first bullet point above will be subject to tax at generally applicable U.S. federal income tax rates as if the Non-U.S. Holder were a U.S. resident. Any gains described in the first bullet point above of a corporate Non-U.S. Holder may also be subject to an additional “branch profits tax” at a thirty percent (30%) rate (or a lower applicable income tax treaty rate). If the second bullet point applies to a Non-U.S. Holder, such Non-U.S. Holder will be subject to U.S. tax on such Non-U.S. Holder’s net capital gain for such year (including any gain realized in connection with the redemption) at a tax rate of thirty percent (30%).

If the third bullet point above applies to a Non-U.S. Holder, gain recognized by such holder will be subject to tax at generally applicable U.S. federal income tax rates. In addition, U.S. federal withholding at a rate of fifteen percent (15%) of the amount realized upon such sale or other exchange may apply, unless shares of Common Stock or Preferred Stock, as applicable, are considered regularly traded on an established securities market. Whether Perimeter Delaware is a “United States real property holding corporation” is fact specific and depends on the composition of its assets. Perimeter Delaware does not expect that it would be a “United States real property holding corporation” immediately after Redomiciliation Transaction is completed and/or for the foreseeable future. Due to the factual nature of the determination, no assurance can be provided as to whether Perimeter Delaware would be or would not be treated as a “United States real property holding corporation” in any future year.

NON-U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS AS TO THE TAX CONSEQUENCES TO THEM OF THE POSSIBILITY OF PERIMETER DELAWARE’S STATUS AS UNITED STATES REAL PROPERTY HOLDING CORPORATION.

Redemption of Preferred Stock by Perimeter Delaware

The U.S. federal income tax consequences to a Non-U.S. Holder of Preferred Stock resulting from redemption of Preferred Stock by Perimeter Delaware will depend on whether the redemption qualifies as a sale of shares of Preferred Stock under Section 302 of the Code. If such a redemption qualifies as a sale of Preferred Stock, the U.S. federal income tax consequences to the Non-U.S. Holder will be as described above under “—Sale, Taxable Exchange or Other Taxable Disposition of Perimeter Delaware Stock.” If such a redemption does not qualify as a sale of Preferred Stock, the Non-U.S. Holder will be treated as receiving a corporate distribution, the U.S. federal income tax consequences of which are described above under “—Distributions on Perimeter Delaware Stock.”

A redemption of shares of Preferred Stock generally will be treated as a sale or exchange if it:

all within the meaning of Section 302(b) of the Code.

In determining whether any of these tests has been met, shares of the capital stock of Perimeter Delaware, including the Preferred Stock and other equity interests, considered to be owned by the Non-U.S. Holder by reason of certain constructive ownership rules set forth in the Code, as well as shares of the capital stock of

81

Perimeter Delaware actually owned by the Non-U.S. Holder, generally must be taken into account. Because the determination as to whether any of the alternative tests of Section 302(b) of the Code will be satisfied with respect to the Non-U.S. Holder depends upon the facts and circumstances at the time that the determination must be made, Non-U.S. Holders are advised to consult their tax advisors to determine such tax treatment.

In order to meet the “substantially disproportionate” test, the percentage of Perimeter Delaware’s outstanding voting stock actually and constructively owned by the Non-U.S. Holder immediately following the redemption of Preferred Stock must, among other requirements, be less than eighty percent (80%) of the percentage of Perimeter Delaware’s outstanding voting stock actually and constructively owned by the Non-U.S. Holder immediately before the redemption.

There will be a “complete termination” of a Non-U.S. Holder’s interest if either (1) all of the shares of Perimeter Delaware stock actually and constructively owned by the Non-U.S. Holder are redeemed or (2) all of the shares of Perimeter Delaware stock actually owned by the Non-U.S. Holder are redeemed and the Non-U.S. Holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of stock owned by certain family members and the Non-U.S. Holder does not constructively own any other shares of Perimeter Delaware stock.

The redemption of the Preferred Stock will “not be essentially equivalent to a dividend” if the redemption results in a “meaningful reduction” of the U.S. Holder’s proportionate interest in Perimeter Delaware. Whether the redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in Perimeter Delaware will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation where such stockholder exercises no control over corporate affairs may constitute such a “meaningful reduction.”

If none of the foregoing tests is satisfied, then the redemption of shares of the Preferred Stock will be treated as a corporate distribution to the redeemed Non-U.S. Holder.

Because it may not be certain at the time a Non-U.S. Holder’s Preferred Stock is redeemed whether such redemption will be treated as a sale of shares or a corporate distribution, and because such determination will depend in part on a Non-U.S. Holder’s particular circumstances, the applicable withholding agent may not be able to determine whether (or to what extent) a Non-U.S. Holder is treated as receiving a dividend for U.S. federal income tax purposes. Therefore, the applicable withholding agent may withhold U.S. withholding tax at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty) on the gross amount of any consideration paid to a Non-U.S. Holder in redemption of such Non-U.S. Holder’s Preferred Stock, unless (i) the applicable withholding agent has established special procedures allowing Non-U.S. Holders to certify that they are exempt from such withholding tax and (ii) such Non-U.S. Holders are able to certify that they meet the requirements of such exemption (e.g., because such Non-U.S. Holders are not treated as receiving a dividend under the Section 302 of the Code tests described above). However, there can be no assurance that any applicable withholding agent will establish such special certification procedures. If an applicable withholding agent withholds excess amounts from the amount payable to a Non-U.S. Holder, such Non-U.S. Holder generally may obtain a refund of any such excess amounts by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their own tax advisors regarding the application of the foregoing rules in light of their particular facts and circumstances and any applicable procedures or certification requirements.

Information Reporting Requirements and Backup Withholding

Information returns will be filed with the IRS in connection with payments of dividends on and the proceeds from a sale or other disposition of Common Stock and Preferred Stock. A Non-U.S. Holder may have to comply with certification procedures to avoid such information reporting and backup withholding requirements. The certification procedures required to claim a reduced rate of withholding under a treaty generally will satisfy the

82

certification requirements necessary to avoid backup withholding as well. Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a Non-U.S. Holder may be allowed as a credit against such Non-U.S. Holder’s U.S. federal income tax liability and may entitle such Non-U.S. Holder to a refund, provided that the required information is timely furnished to the IRS.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code and the Treasury Regulations and administrative guidance promulgated thereunder (commonly referred to as “FATCA”) impose withholding of thirty percent (30%) on payments of dividends (including constructive dividends) on Perimeter Delaware Stock to “foreign financial institutions” (which is broadly defined for this purpose and in general includes investment vehicles) and certain other non-U.S. entities unless various U.S. information reporting and due diligence requirements (generally relating to ownership by U.S. persons of interests in or accounts with those entities) have been satisfied by, or an exemption applies to, the payee (typically certified as to by the delivery of a properly completed IRS Form W-8BEN or W-8BEN-E). Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules. Under certain circumstances, a Non-U.S. Holder might be eligible for refunds or credits of such withholding taxes, and a Non-U.S. Holder might be required to file a U.S. federal income tax return to claim such refunds or credits. Withholding under FATCA was scheduled to apply to payments of gross proceeds from the sale or other disposition of property that produces U.S.-source interest or dividends beginning on January 1, 2019, but on December 13, 2018, the IRS released proposed regulations that, if finalized in their proposed form, would eliminate the obligation to withhold on gross proceeds. Such proposed regulations also delayed withholding on certain other payments received from other foreign financial institutions that are allocable, as provided for under final Treasury Regulations, to payments of U.S.-source dividends, and other fixed or determinable annual or periodic income. Although these proposed Treasury Regulations are not final, taxpayers generally may rely on them until final Treasury Regulations are issued. Non-U.S. Holders should consult their tax advisors regarding the effects of FATCA on their ownership and disposition of Perimeter Delaware Stock.

LUXEMBOURG TAX CONSIDERATIONS

This summary is based on the laws, regulations and applicable tax treaties as in effect on the date hereof in the Grand Duchy of Luxembourg, all of which are subject to change, possibly with retroactive effect. Existing Ordinary Shareholders and Existing Preferred Shareholders should consult their own tax advisers as to the particular tax consequences, under the tax laws of the country of which they are residents, citizens, domiciled or incorporated for tax purposes of the Redomiciliation Transaction.

The following is a summary addressing certain material Luxembourg tax consequences that are likely to be relevant to Perimeter Luxembourg, Perimeter Delaware, non-Luxembourg-resident Existing Ordinary Shareholders and non-Luxembourg-resident Existing Preferred Shareholders in the context of the Redomiciliation Transaction.

This summary does not purport to address all material tax considerations that may be relevant to a holder of Existing Shares. These tax consequences will vary in accordance with the law and practice currently in force in the holders’ country of citizenship, residence, domicile or incorporation and with their personal circumstances.

Perimeter Luxembourg and its management have engaged professional tax advisors who have assessed that no material corporate-level Luxembourg taxes should be expected for Perimeter Luxembourg or Perimeter Delaware in the context of the Redomiciliation Transaction. However, the Luxembourg tax authorities may assert, or a Luxembourg court may sustain, a contrary position, and no assurances can be given that the Redomiciliation Transaction will not result in material corporate-level Luxembourg taxes for Perimeter Luxembourg or Perimeter Delaware.

1. Luxembourg Tax Considerations for Perimeter Luxembourg and Perimeter Delaware

The Redomiciliation Transaction may result in material Luxembourg taxes for Perimeter Luxembourg or Perimeter Delaware.

For Luxembourg tax purposes, the Redomiciliation Transaction should be considered as a deemed disposal of all the assets and liabilities of Perimeter Luxembourg at their fair market value. Luxembourg corporate income tax at the aggregate rate of 24.94% (for Luxembourg City) should be due on the taxable net capital gains and other taxable profits arising from the Redomiciliation Transaction. However, Perimeter Luxembourg’s principal assets consist of either shareholdings that should qualify for the Luxembourg participation exemption on capital gains or shareholdings that should not have any material appreciation in value since their acquisition by Perimeter Luxembourg.

2. Luxembourg Taxation Considerations for non-resident Existing Ordinary Shareholders and non-resident Existing Preferred Shareholders

From a Luxembourg tax perspective, the Redomiciliation Transaction should be treated as a deemed disposal of the Existing Ordinary Shares or Existing Preferred Shares at their fair market value, which may trigger the application of Luxembourg non-resident capital gain taxation rules for such Existing Shareholders if certain conditions are met.

An individual or corporate non-Luxembourg resident holder of Existing Ordinary Shares or Existing Preferred Shares who/which realizes a gain on disposal (including deemed disposal) thereof (and who/which does not have a permanent establishment or permanent representative in the Grand Duchy of Luxembourg to which Existing Ordinary Shares or Existing Preferred Shares would be attributable) will only be subject to Luxembourg taxation on capital gains arising upon disposal of such shares if such holder has (together with his or her spouse and underage children) directly or indirectly held more than 10% of the capital of Perimeter Luxembourg, at any time during the past five years, and either (1) such holder has been a resident of

84

Luxembourg for tax purposes for at least 15 years and has become a non-resident within the last five years preceding the realization of the gain, subject to any applicable tax treaty, or (2) the disposal of Existing Ordinary Shares or Existing Preferred Shares occurs within six months from their acquisition, subject to any applicable tax treaty.

The Redomiciliation Transaction will be subject to a fixed registration duty of EUR 75 in Luxembourg.

85

EU MANDATORY DISCLOSURE RULES

On 25 May 2018, the EU Council adopted the Directive 2018/822 amending Directive 2011/16/EU as regards mandatory automatic exchange of information in the field of taxation, that imposes a reporting obligation on parties involved in cross-border transactions that may be associated with aggressive tax planning (“DAC6”).

In the case of a Reportable Arrangement, the information that must be reported includes the name of all relevant taxpayers (e.g., such as Perimeter Luxembourg) and intermediaries as well as an outline of the Reportable Arrangement, the value of the Reportable Arrangement and identification of any member states likely to be concerned by the Reportable Arrangement.

The reporting obligation in principle rests with persons that design, market or organize the Reportable Arrangement and professional advisors (intermediaries). However, in certain cases, the taxpayer itself can be subject to the reporting obligation.

The information reported will be automatically exchanged between the tax authorities of all EU Member States.

DAC6 has been implemented into Luxembourg law on 25 March 2020 (the “DAC6 Law”) and is applicable as from 1 July 2020.

In light of the broad scope of DAC6 and DAC6 Law, the Redomiciliation Transaction may fall within the scope of the DAC6 Law and thus be reportable as described above.

86

MANAGEMENT OF PERIMETER DELAWARE

The persons who will serve as directors and executive officers of Perimeter Delaware after giving effect to the Redomiciliation Transaction are expected to be the same persons currently serving as directors and officers of Perimeter Luxembourg. As of the date of this Proxy/Prospectus, the Perimeter Luxembourg Board is comprised of ten directors, eight of whom are non-employee directors and six of whom are independent.

The information required to be disclosed with respect to each director and executive officer of Perimeter Luxembourg is incorporated by reference from Perimeter Luxembourg’s Definitive Proxy Statement on Schedule 14A, filed with the SEC on April 12, 2024.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

The persons who will serve as directors and officers of Perimeter Delaware after giving effect to the Redomiciliation Transaction are expected to be the same persons currently serving as directors and officers of Perimeter Luxembourg. Except as described in in this Proxy/Prospectus, the information required to be disclosed with respect to each director and executive officer of Perimeter Luxembourg is incorporated by reference from Perimeter Luxembourg’s Definitive Proxy Statement on Schedule 14A, filed with the SEC on April 12, 2024.

Transactions Related to the Redomiciliation Transaction

Other than as set forth in this Proxy/Prospectus, Perimeter Luxembourg is not aware of any material interests, direct or indirect, by way of beneficial ownership of securities or otherwise, of any director or executive officer, nominee for election as a director or any Existing Shareholder holding more than 10% of the voting rights attached to the Existing Shares or an associate or affiliate of any of the foregoing in any transaction since January 1, 2021, or in any proposed or ongoing transaction of Perimeter Luxembourg, in any matter to be acted upon in the Special Meeting. 

Indemnification Agreements

Perimeter Delaware intends to enter into separate indemnification agreements with its directors and executive officers, in addition to the indemnification provided for in the Proposed Organizational Documents. These agreements, among other things, will require Perimeter Delaware to indemnify its directors and executive officers for certain expenses, including attorneys’ fees, judgments, fines, and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of Perimeter Delaware’s directors or executive officers or as a director or executive officer of any other company or enterprise to which the person provides services at Perimeter Delaware’s request. Perimeter Delaware believes that these provisions in the Proposed Organizational Documents and indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

91

DESCRIPTION OF PERIMETER DELAWARE SECURITIES

The following description of Perimeter Delaware’s securities, following completion of the Redomiciliation Transaction, is a summary. This summary is qualified by the complete text of the Proposed Charter and Proposed Bylaws to be in effect upon completion of the Redomiciliation Transaction, which will be substantially in the forms attached as Annexes A and B, respectively, to this Proxy/Prospectus. We encourage you to read those documents carefully.

There are differences between the Existing Articles and the Proposed Organizational Documents as they are expected to be in effect upon completion of the Redomiciliation Transaction, especially relating to changes that are required by Delaware law. For example, certain provisions of the Existing Articles were not replicated in the Proposed Organizational Documents because the DGCL would not permit such replication. In addition, the Proposed Organizational Documents provide for certain other provisions customarily provided with respect to publicly-traded Delaware corporations. See “Comparison of Shareholder Rights between Luxembourg Law and Delaware Law.”

Authorized Share Capital

Our authorized capital stock following the Redomiciliation Transaction will consist of 4,000,000,000 shares of Common Stock and 20,000,000 shares of Preferred Stock. Unless otherwise required, we will issue all shares of our capital stock in uncertificated form.

Common Stock

Upon effectiveness of the Redomiciliation Transaction, we expect that 164,628,366 shares of Common Stock will be issued and outstanding, assuming all holders of the Existing Warrants exercise such warrants prior to the expiration thereof.

Holders of Common Stock will be 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 will be determined by a majority of the votes cast by the stockholders entitled to vote on the election. Holders of Common Stock will be entitled to receive proportionately any dividends as may be declared by the Perimeter Delaware Board, subject to any preferential dividend rights of any series of preferred stock outstanding or that we may designate and issue in the future.

In the event of our liquidation, dissolution, or winding up, the holders of Common Stock will be 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. Holders of Common Stock will have no preemptive, subscription, redemption, or conversion rights. There will be no sinking fund provisions applicable to our Common Stock. The rights, preferences, and privileges of holders of Common Stock will be subject to, and may be adversely affected by, the rights of the holders of shares of any series of Preferred Stock outstanding or that we may designate and issue in the future.

Preferred Stock

Upon effectiveness of the Redomiciliation Transaction, we expect that 10,000,000 shares of Preferred Stock will be issued and outstanding.

Under the terms of our Proposed Charter, the Perimeter Delaware Board will be authorized to direct us to issue shares of Preferred Stock in one or more series without stockholder approval. The Perimeter Delaware Board will have the discretion to determine the rights, preferences, privileges, and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges, and liquidation preferences, of each series of preferred stock.

92

The purpose of authorizing the Perimeter Delaware Board to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of Preferred Stock, while providing flexibility in connection with possible acquisitions, future financings, and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of our outstanding voting stock. We have no present plans to issue any shares of Preferred Stock other than the Series A Preferred Stock discussed below.

Series A Preferred Stock

Upon effectiveness of the Redomiciliation Transaction, the Existing Preferred Shares will automatically convert into 10,000,000 shares of Preferred Stock to be designated as the Series A Preferred Stock (shares of such series, the “Series A Preferred Shares”).

As long as the Series A Preferred Shares are in issue and outstanding, no preferred shares ranking pari passu or senior to the Series A Preferred Shares will be issued by the Company, other than additional Series A Preferred Shares or other equity security interests issued with the consent of a majority of holders of the Series A Preferred Shares.

Each Series A Preferred Share is entitled to a preferred annual cumulative right to a dividend amounting to 6.5% (the “Regular Dividend Rate”) of its liquidation preference (the “Preferential Dividend”). The Preferential Dividend will be paid each year within three business days following the holding of the annual meeting of the Company’s shareholders (each, a “Preferential Dividend Payment Date”). On each Preferential Dividend Payment Date, 40% of the Preferential Dividend for such year (or 50% of the Preferential Dividend for such year if the Company paid a dividend on shares of Common Stock during the period since the last Preferential Dividend Payment Date) will be paid in cash and the remainder of the Preferential Dividend will be paid in kind, unless the Company elects to pay any additional portion of the Preferential Dividend in cash; provided that, (x) the Company will not be required to pay any portion of such annual Preferential Dividends in cash on a Preferential Dividend Payment Date to the extent that it or its subsidiaries are prohibited from paying such portion of the annual Preferential Dividend in cash under either (i) that certain senior credit facility agreement to which the Company and/or certain of its subsidiaries is a party (the “Senior Credit Agreement”) or (ii) that certain senior secured notes indenture to which the Company and/or certain of its affiliates is a party (the “Secured Notes”), and (y) in the event that the Company or its subsidiaries are so prohibited from paying all or a portion of such Preferential Dividends in cash as described in the foregoing clause (x), the Company will pay the maximum amount not prohibited by the Senior Credit Agreement or the Secured Notes in cash. If the Company fails to pay any portion of the cash portion of the Preferential Dividend for any reason in a given year by the Preferential Dividend Payment Date (including due to clause (x) of the immediately preceding sentence), then (i) the Preferential Dividend rate for such year (i.e., the year in which the Company fails to pay any portion of the cash portion of the Preferential Dividend Payment), but not necessarily the subsequent year, will increase to the interest rate being paid (whether default or not) at such time under the Senior Credit Agreement, plus 5% (the “Increased Dividend Rate”) and (ii) the Preferential Dividend Rate for the following year will be reset at the Regular Dividend Rate and will be subject to increase to the Increased Dividend Rate for such year (but not necessarily the subsequent year) if the Company fails to pay any portion of the cash portion of the Preferential Dividend Payment by the Preferential Dividend Payment Date for such year.

The Company may redeem the Series A Preferred Shares at any time prior to the earliest of (i) April 30, 2030, (ii) November 9, 2030, or (iii) upon the occurrence of a Change of Control (as defined in the Proposed Charter) (such date, the “Maturity Date”), at the Company’s sole option. The redemption price per share would be equal to the liquidation preference of the Series A Preferred Shares, plus any accrued and unpaid Preferential Dividend, if any. If the Company fails to redeem the Series A Preferred Shares at the Maturity Date, the Preferential Dividend rate will permanently increase to the interest rate currently being paid (whether default or not) under the Senior Credit Agreement, plus 10%.

93

As long as Series A Preferred Shares are issued and outstanding, the Company and its subsidiaries will not (a) enter into a credit agreement or (b) amend the Senior Credit Agreement, in each case, in a manner that would adversely affect the redemption rights of the Series A Preferred Shares by extending the maturity date under such credit facility beyond the Maturity Date or increase the restrictions on the Company’s ability to pay the cash portion of Preferential Dividends without the consent of holders owning a majority of the shares of Series A Preferred Shares. If, in any year, the Company fails to make any portion of the cash portion of any Preferential Dividend by the Preferential Dividend Payment Date, then, during the following year, the Company may not, without the consent of the holders of a majority of the outstanding Series A Preferred Shares, pay a cash dividend on the Common Stock until such time as the Company has paid the cash portion of the Preferential Dividend Payment for such following year (which cash portion of the Preferential Dividend Payment may be paid by the Company in advance of the Preferential Dividend Payment Date for, and at any time during, such following year). Such restrictions will not apply to any non-pro rata purchase, repurchase, or redemption of any equity securities of the Company or any of its subsidiaries. As long as Series A Preferred Shares are issued and outstanding, during the occurrence and continuance of a default by the Company to pay any Preferential Dividend (for the avoidance of doubt, the payment of any cash portion of the Preferential Dividend in kind in accordance with the terms of the Proposed Charter will not constitute a default by the Company), the approval of holders owning a majority of the outstanding Series A Preferred Shares will be required (i) for the declaration of dividends to the benefit of all other categories of capital stock issued and outstanding and (ii) for the purchase, repurchase, or redemption of any equity securities of the Company or any of its subsidiaries (other than pursuant to equity incentive agreements with employees).

Series A Preferred Shares are not entitled to vote, save for the matters provided for by the DGCL and in the Proposed Charter.

Series A Preferred Shares will be non-voting shares and will not be included for the calculation of the quorum and majority at each meeting of Company shareholders, save for the matters provided for by the DGCL and the Proposed Charter.

The rights attached to the Series A Preferred Shares under the Proposed Charter will not be amended in a manner adverse to the Series A Preferred Shares without the consent of holders owning a majority of the Series A Preferred Shares.

Exclusive Forum

The Proposed Organizational Documents will provide that, subject to limited exceptions and unless Perimeter Delaware consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the exclusive forum for (i) any derivative action, suit or proceeding brought on behalf of the Perimeter Delaware, (ii) any action, suit or proceeding asserting a claim of breach of a fiduciary duty owed by any director, officer or stockholder of Perimeter Delaware to Perimeter Delaware or to its stockholders, (iii) any action, suit or proceeding arising pursuant to any provision of the DGCL or the Proposed Organizational Documents (as either may be amended from time to time) or (iv) any action, suit or proceeding asserting a claim against Perimeter Delaware governed by the internal affairs doctrine.

The forum selection provision in the Proposed Organizational Documents does not apply to establish the Court of Chancery of the State of Delaware as the forum for actions or proceedings brought to enforce a duty or liability created by the Securities Act or the Exchange Act. Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all claims brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder and our Proposed Organizational Documents will provide that the federal district courts of the United States of America will, to the fullest extent permitted by law, be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. While there can be no assurance that federal or state courts will determine that our federal forum provision should be enforced in a particular case, application of our federal forum provision means that suits brought by

94

our stockholders to enforce any duty or liability created by the Securities Act must be brought in federal court and cannot be brought in state court.

Section 27 of the Exchange Act creates exclusive federal jurisdiction over all claims brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder and our Proposed Bylaws will provide that the federal district courts of the United States of America will, to the fullest extent permitted by law, be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Exchange Act. Accordingly, actions by our stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in federal court. Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder.

For more information on the risks associated with our choice of forum provision, see “Risk Factors—Risks Relating to Perimeter Delaware—The Proposed Organizational Documents will designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by stockholders, which could limit stockholders’ ability to obtain a favorable judicial forum for disputes with Perimeter Delaware or its directors or officers or other matters pertaining to Perimeter Delaware’s internal affairs.”

Certain Anti-Takeover Matters

Certain provisions of the Proposed Organizational Documents and the DGCL could have the effect of delaying, deferring, or discouraging another party from acquiring Perimeter Delaware. These provisions encourage persons considering unsolicited tender offers or other unilateral takeover proposals to negotiate with the Perimeter Delaware Board rather than pursue non-negotiated takeover attempts. These provisions include the below summarized items.

Requirements for Advance Notification of Stockholder Meetings, Nominations and Proposals

Our Proposed Charter will provide that special meetings of the stockholders may be called only by the Perimeter Delaware Board and not by our stockholders or any other person or persons. Our Proposed Organizational Documents prohibit the conduct of any business at a special meeting other than as specified in the notice for such meeting. In addition, any stockholder who wishes to bring business before an annual meeting or nominate directors must comply with the advance notice requirements set forth in our Proposed Bylaws. These provisions may have the effect of deferring, delaying or discouraging hostile takeovers or changes in control of us or our management.

Stockholder Action by Written Consent

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 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 Proposed Charter provides otherwise. Our Proposed Charter, consistent with the Existing Articles and Luxembourg law, will prohibit stockholder action by written consent (and, thus, requires that all stockholder actions be taken at a meeting of our stockholders).

Board of Directors Vacancies

Our Proposed Organizational Documents will authorize only the Perimeter Delaware Board to fill vacant directorships, including newly created seats. In addition, the number of directors constituting the Perimeter Delaware Board will be permitted to be set only by a resolution adopted by a majority vote of the entire

95

Perimeter Delaware Board. These provisions would prevent a stockholder from increasing the size of the Perimeter Delaware Board and then gaining control of such board by filling the resulting vacancies with its own nominees. This will make it more difficult to change the composition of the Perimeter Delaware Board and will promote continuity of management.

No Cumulative Voting

The DGCL provides that stockholders are not entitled to cumulate votes in the election of directors unless a corporation’s certificate of incorporation provides otherwise. Our Proposed Charter will not provide for cumulative voting.

Issuance of Undesignated Preferred Stock

Subject to the rights granted to the holders of Series A Preferred Shares, the Perimeter Delaware Board will have the authority, without further action by our stockholders, to issue up to 10,000,000 additional shares of undesignated Preferred Stock with rights and preferences, including voting rights, designated from time to time by the Perimeter Delaware Board. The existence of authorized but unissued shares of Preferred Stock would enable the Perimeter Delaware Board to render more difficult or to discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest, or other means.

NYSE Listing

The Existing Ordinary Shares are currently listed on the NYSE under the symbol “PRM” and the Existing Warrants are currently quoted on the OTC Market under the symbol “PRMFF.” We expect the Common Stock to continue to trade under the same symbol on the NYSE following the Redomiciliation Transaction. We do not expect to have warrants listed for trading on any securities exchange or included in any automatic quotation system following the Redomiciliation Transaction as our Existing Warrants are expected to expire prior to the Special Meeting. There is no assurance that Perimeter Delaware will be able to continue to satisfy the NYSE listing criteria following the consummation of the Redomiciliation Transaction. The Existing Preferred Shares are not currently, and we do not intend for the Preferred Stock to be, listed for trading on any securities exchange or included in any automatic quotation system.

Transfer Agent and Registrar

The transfer agent and registrar for our capital stock is Computershare Trust Company, N.A.

Limitation of Personal Liability of Directors and Officers

The Proposed Charter will provide that, to the fullest extent permitted by law, Perimeter Delaware will have the power to provide rights to indemnification to its current and former officers, directors, employees and agents and to any person who is or was serving at the request of Perimeter Delaware as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

The Proposed Bylaws will provide that Perimeter Delaware will indemnify and hold harmless, to the fullest extent permitted by the DGCL as it presently exists or may later be amended, any director or officer of Perimeter Delaware who was or is made or is threatened to be made a party or is otherwise involved in any proceeding by reason of the fact that he or she, or a person for whom he or she is the legal representative, is or was a director or officer of Perimeter Delaware or, while serving as a director or officer of Perimeter Delaware, is or was serving at the request of Perimeter Delaware as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys’ fees, judgments, fines ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred by such person in connection with any such proceeding.

96

Furthermore, the Proposed Bylaws will provide that Perimeter Delaware may purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of Perimeter Delaware, or is or was serving at the request of Perimeter Delaware as a director, officer, employee or agent of another entity against any liability asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not Perimeter Delaware would have the power to indemnify him or her against such liability under the provisions of the DGCL.

Under the DGCL, no such elimination of liability is permitted (i) for any breach of the director’s duty of loyalty to Perimeter Delaware or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) for unlawful payment of dividend or unlawful share purchase or redemption, or (iv) for any transaction from which the director derived an improper personal benefit.

97

STOCKHOLDER PROPOSALS

If the Redomiciliation Transaction is consummated and Perimeter Delaware holds an annual general meeting in 2025 (the “2025 Annual Meeting”), it will provide notice of or otherwise publicly disclose the date on which the 2025 Annual Meeting will be held. Any proposal intended to be presented for action at the 2025 Annual Meeting by any holder of Common Stock must be received by the Secretary of the Company at its principal executive offices in accordance with the advance notification provisions set out in the Proposed Bylaws in order for such proposal to be considered for inclusion in the Company’s proxy statement and form of proxy relating to the 2025 Annual Meeting. Nothing in this paragraph shall be deemed to require the Company to include any shareholder proposal that does not meet all the requirements for such inclusion established by Rule 14a-8 of the Exchange Act.

For other shareholder proposals to be timely (but not considered for inclusion in the proxy statement for the 2025 Annual Meeting), a shareholder’s notice must be received by the Secretary of the Company not less than 90 days nor more than 120 days prior to the one-year anniversary of the preceding year’s annual meeting, subject to certain exceptions, and comply with the additional requirements of Rule 14a-19(b). In addition, the proposal and the shareholder must comply with Rule 14a-4 under the Exchange Act. In the event that a shareholder proposal intended to be presented for action at the 2025 Annual Meeting is not timely, proxies solicited by the Perimeter Delaware Board in connection with the 2025 Annual Meeting will be permitted to use their discretionary voting authority with respect to the proposal, whether or not the proposal is discussed in the proxy statement for the 2025 Annual Meeting.

Any shareholder proposal will also have to meet all other requirements contained in our Proposed Organizational Documents.

ARTICLE III

The purpose of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware (the “DGCL”) as it now exists or may hereafter be amended and supplemented. The Corporation is being incorporated in connection with the domestication of Perimeter Solutions, SA, a société à responsabilité limitée (limited liability company) duly incorporated and validly existing under the laws of the Grand Duchy of Luxembourg (“LuxCo”), to a Delaware corporation, and this Certificate of Incorporation is being filed simultaneously with the Certificate of Corporate Domestication of LuxCo (the “Certificate of Domestication”).

Any stock certificate that, immediately prior to the Effective Time, represented Ordinary Shares or Preferred Shares of LuxCo will, from and after the Effective Time, automatically and without the necessity of presenting the same for exchange, represent the same number of shares of the Common Stock or Series A Preferred Stock, as applicable.

ARTICLE V

4. Liquidation.

Without limiting the generality of the foregoing, the resolution or resolutions providing for the creation and issuance of any series of Preferred Stock may provide that such series shall be superior or rank equally or be junior to any other series of Preferred Stock to the extent permitted by law and this Certificate (including any Certificate of Designation). Except as otherwise required by law, holders of any series of Preferred Stock shall be entitled only to such voting rights, if any, as shall expressly be granted thereto by this Certificate (including any Certificate of Designation).

Subject to the rights of any holders of any outstanding series of Preferred Stock, the number of authorized shares of Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) without a separate vote of the holders of the outstanding shares of Preferred Stock, irrespective of the provisions of Section 242(b)(2) of the DGCL.

The notice shall identify the Series A Preferred Stock to be redeemed and shall state:

(i) the section of this Certificate pursuant to which the redemption shall occur;

(ii) the Stated Value of the Series A Preferred Stock to be redeemed;

(iii) the Redemption Date;

(iv) the Redemption Price;

(v) if the Corporation is not permitted by applicable law to redeem all of the Series A Preferred Stock required to be redeemed or if the Series A Preferred Stock is to be redeemed in part only (subject to Article V(B)(2)(a)(2)), the portion of the Stated Value of the Series A Preferred Stock to be redeemed and that, after the Redemption Date, upon surrender of such Series A Preferred Stock, a new certificate, if applicable, for such Series A Preferred Stock in a Stated Value equal to the unredeemed portion of the original Series A Preferred Stock will be issued in the name of the Series A Holder upon cancellation of the original certificate, if any, representing such Series A Preferred Stock;

(vi) that the certificate, if any, representing the Series A Preferred Stock (or an affidavit of loss in lieu thereof) called for redemption must be surrendered to the Corporation to collect the Redemption Price;

(vii) that, unless the Corporation defaults in making such redemption payment, the Series A Preferred Stock called for redemption shall cease to accrue the Preferential Dividends on and after the Redemption Date; and

(viii) any condition to such redemption (which may be waived by the Corporation in its sole discretion).

Solely in the case of optional redemption in accordance with Article V(B)(2)(a)(7), such notice of redemption, and the related redemption, may, at the Corporation’s discretion, be subject to one or more conditions precedent and the surrender of any certificate(s) representing the Series A Preferred Stock (or an affidavit of loss in lieu thereof) called for redemption (which may be waived by the Corporation in its sole discretion).

The Corporation may provide in such notice that payment of the Redemption Price and performance of the Corporation’s obligations with respect to such redemption may be performed by another Person; provided that the Corporation shall remain liable for any failure by such Person to pay such Redemption Price or perform such obligations.

If less than all of the Series A Preferred Stock are to be redeemed at any time, the Series A Preferred Stock of all Series A Holders shall be redeemed on a pro rata basis in proportion to the aggregate Stated Value of all Series A Preferred Stock held by each Series A Holder.

(3) Effect of Notice of Redemption. Once notice of redemption is delivered to the Series A Holders in accordance with Article V(B)(2)(a)(1) hereof, subject to satisfaction, or waiver by the Corporation, of any conditions precedent relating thereto specified in the applicable notice of redemption, the Redemption Price of the Series A Preferred Stock called for redemption shall become irrevocably due and payable on the Redemption Date. The notice, if delivered, mailed, or caused to be mailed in a manner specified in Article V(B)(2)(a)(1) hereof, shall be conclusively presumed to have been given, whether or not the Series A Holder receives such notice. In any case, failure to deliver such notice or any defect in the notice to the Series A Holder of any share of Series A Preferred Stock designated for redemption, in whole or in part, shall not affect the validity of the proceedings for the redemption of any other share of Series A Preferred Stock.

(4) Deposit of Redemption Price.

(i) The aggregate Redemption Price will be due and payable, and paid in cash in immediately available funds, to the respective Series A Holders of the Series A Preferred Stock on the applicable Redemption Date, subject to satisfaction, or waiver by the Corporation, of any conditions precedent relating thereto specified in the applicable notice of redemption. Prior to 2:00 p.m., New York City time, on the Redemption Date, the Corporation shall deposit with each Series A Holder money sufficient to pay the Redemption Price of all Series A Preferred Stock of such Series A Holder to be redeemed on that Redemption Date, subject to satisfaction, or waiver by the Corporation, of any conditions precedent relating thereto specified in the applicable notice of redemption. Each such Series A Holder shall promptly return to the Corporation any money deposited with the Series A Holders by the Corporation in excess of the amounts necessary to pay the Redemption Price, of, and accumulated and unpaid Preferential Dividends on, all Series A Preferred Stock of such Series A Holder to be redeemed.

(ii) If the Corporation complies with the provisions of Article V(B)(2)(a)(4)(i), on and after the Redemption Date, Preferential Dividends shall cease to accrue on the Series A Preferred Stock or the portions of Series A Preferred Stock called for redemption. If the amounts required to be paid in respect of any share of Series A Preferred Stock called for redemption shall not be so paid upon surrender for redemption because of the failure of the Corporation to comply with Article V(B)(2)(a)(4)(i), without prejudice to any other rights that a Series A Holder may have at law or in equity, the Corporation shall pay on the date on which such amounts are actually paid, an additional amount equal to the amount of Preferential Dividends that would have accrued on (x) the unpaid Stated Value of such share of Series A Preferred Stock, from the Redemption Date until such Stated Value is paid, and (y) to the extent lawful on any Preferential Dividends accumulated to the Redemption Date not paid on such unpaid Stated Value, in each case, at the Regular Dividend Rate.

(5) Series A Preferred Stock Redeemed in Part. Upon surrender of any Series A Preferred Stock certificate that is redeemed in part, the Corporation shall issue a new Series A Preferred Stock certificate equal in Stated Value to the unredeemed portion of the Series A Preferred Stock surrendered.

(6) Maturity Date. Immediately upon the occurrence of the earliest of:

(i) six months after October 30, 2029 (i.e., April 30, 2030);

(ii) nine years after the date of original issuance of the Preferred Shares by LuxCo that became the Series A Preferred Shares at the Effective Time; or

(iii) a Change of Control (as defined below), any liquidation, dissolution, or winding up of the Corporation (whether voluntary or involuntary) or the voluntary or involuntary bankruptcy of the

4

Corporation (the term “Change of Control” means (x) the sale of all or substantially all the assets of the Corporation and its subsidiaries (taken as a whole); or (y) any merger, consolidation, recapitalization, or reorganization of the Corporation, unless, following such merger, consolidation, recapitalization, or reorganization, the holders of the Corporation’s securities prior to such merger, consolidation, recapitalization, or reorganization continue to hold (directly or indirectly) at least 50% of the voting rights in the surviving entity (or the parent company of the surviving entity)) (the earliest of clauses (i) through (iii) above, the “Maturity Date”),

to the fullest extent permitted by law, the Corporation shall redeem for cash all of the then-outstanding shares of Series A Preferred Stock at (and each share of Series A Preferred Stock shall be entitled to receive and to be paid out of the assets of the Corporation legally available for distribution to the Corporation’s stockholders, before any distribution or payment may be made to a holder of any other Shares by reason of their ownership thereof) a price per share equal to the Redemption Price as of the Redemption Date. If a redemption pursuant to this Article V(B)(2)(a)(6) is triggered and the Corporation does not have funds legally available for the redemption of all outstanding shares of Series A Preferred Stock, the Corporation shall redeem a pro rata portion of each Series A Holder’s shares of Series A Preferred Stock to the fullest extent of such funds legally available, based on the respective amounts that would otherwise be payable in respect of the Series A Preferred Stock to be redeemed if the Corporation’s legally available funds were sufficient to redeem all such shares, and shall redeem the remaining shares of Series A Preferred Stock as soon as practicable after the Corporation has funds legally available therefor. If the Corporation fails to redeem any Series A Preferred Stock at the Maturity Date, the Preferential Dividend rate will permanently increase to the interest rate currently being paid (whether default or not) under the Senior Credit Agreement, plus 10%. The Corporation shall use reasonable best efforts to generate sufficient funds legally available to redeem all outstanding shares of Series A Preferred Stock, including by way of incurrence of indebtedness, issuance of equity, sale of assets, effecting a merger or similar transaction, or otherwise. At any time thereafter when additional funds are legally available for the redemption of the Series A Preferred Stock, such funds will immediately be used to redeem the balance of the Series A Preferred Stock. Notwithstanding the foregoing, a redemption otherwise required by this Article V(B)(2)(a)(6) shall not be required in connection with any Change of Control whereby the Series A Preferred Stock is purchased (at the then-applicable Redemption Price) in connection with such Change of Control. No holder of Shares that rank junior to the Series A Preferred Stock in respect of payment of dividends or upon liquidation, dissolution, or winding up shall receive any cash or other consideration upon a redemption pursuant to this Article V(B)(2)(a)(6) by reason of their ownership thereof unless the full amount of the Redemption Price to which Series A Holders are entitled in respect of all outstanding Series A Preferred Stock upon such redemption pursuant to this Article V(B)(2)(a)(6) have been paid in full in cash in immediately available funds.

(7) Optional Redemption. At any time prior to the Maturity Date, the Corporation may, on one or more occasions, redeem all (or a part, in accordance with Article V(B)(2)(a)(2) and this Article V(B)(2)(a)(7)) of the outstanding shares of Series A Preferred Stock held by the Series A Holders on a pro rata basis, upon written notice as described under Article V(B)(2)(a)(1) hereof for an amount per share equal to the Redemption Price that shall be paid in cash, subject to the satisfaction, or waiver by the Corporation, of any conditions precedent (including, but not limited to, the consummation of a financing transaction), on the Redemption Date set forth in the notice required under Article V(B)(2)(a)(1) hereof. Any redemption pursuant to this Article V(B)(2)(a)(7) shall be made pursuant to the provisions of Sections 2(a)(1) through 2(a)(5) hereof and, may, for the avoidance of doubt, at the Corporation’s option, be subject to one or more conditions precedent (which may be waived by the Corporation in its sole discretion). For the avoidance of doubt, any redemption pursuant to this Article V(B)(2)(a)(7) shall occur without suffering or supporting any prepayment fee or penalty.

(b) No redemption of Shares other than shares of Series A Preferred Stock shall be carried out if the rights attached to the Series A Preferred Shares hereunder have not been complied with by the

5

Corporation, other than for redemption of Shares pursuant to equity incentive agreements with employees up to a maximum amount of 32,000,000 Shares.

(c) For so long as shares of Series A Preferred Stock are issued and outstanding, no Preferred Stock ranking pari passu or senior to the Series A Preferred Stock shall be issued by the Corporation other than additional shares of Series A Preferred Stock or other Shares issued with the consent of a majority of holders of the outstanding shares of Series A Preferred Stock.

(d) Where shares of Series A Preferred Stock are issued and outstanding, each share of Series A Preferred Stock is entitled to a preferred annual cumulative dividend amounting to 6.5% (the “Regular Dividend Rate”) of its Stated Value (the “Preferential Dividend”). The Preferential Dividend shall be paid each year within three business days following the holding of the annual meeting of stockholders provided for under Article II of the Bylaws of the Corporation (each, a “Preferential Dividend Payment Date”). On each Preferential Dividend Payment Date, 40% of the Preferential Dividend for such year (or 50% of the Preferential Dividend for such year if the Corporation paid a dividend on shares of Common Stock during the period since the last Preferential Dividend Payment Date) shall be paid in cash and the remainder of the Preferential Dividend shall be paid in kind, unless the Corporation elects to pay any additional portion of the Preferential Dividend in cash; provided that, (x) the Corporation shall not be required to pay any portion of such annual Preferential Dividends in cash on a Preferential Dividend Payment Date to the extent that the Corporation or its subsidiaries are prohibited from paying such portion of the annual Preferential Dividend in cash under either (i) that certain senior credit facility agreement to which the Corporation and/or certain of its subsidiaries is a party (as it may be amended and/or restated from time to time, the “Senior Credit Agreement”) or (ii) that certain senior secured notes indenture to which the Corporation and/or certain of its affiliates is a party (the “Secured Notes”), and (y) in the event that the Corporation or its subsidiaries are so prohibited from paying all or a portion of such Preferential Dividends in cash as described in the foregoing clause (x), the Corporation shall pay the maximum amount not prohibited by the Senior Credit Agreement or the Secured Notes in cash. If the Corporation fails to pay any portion of the cash portion of the Preferential Dividend for any reason in a given year by the Preferential Dividend Payment Date (including due to clause (x) of the immediately preceding sentence), then (i) the Preferential Dividend rate for such year (i.e., the year in which the Corporation fails to pay any portion of the cash portion of the Preferential Dividend Payment), but not necessarily the subsequent year, will increase to the interest rate being paid (whether default or not) at such time under the Senior Credit Agreement, plus 5% (the “Increased Dividend Rate”) and (ii) the Preferential Dividend Rate for the following year will be reset at the Regular Dividend Rate and will be subject to increase to the Increased Dividend Rate for such year (but not necessarily the subsequent year) if the Corporation fails to pay any portion of the cash portion of the Preferential Dividend Payment by the Preferential Dividend Payment Date for such year.

(e) As long as shares of Series A Preferred Stock are issued and outstanding, the Corporation shall not, and shall ensure that its subsidiaries do not, (a) enter into a credit agreement or (b) amend the Senior Credit Agreement, in each case, in a manner that would adversely affect the redemption rights of the Series A Preferred Stock by extending the maturity date under such credit facility beyond the Maturity Date or increase the restrictions on the Corporation’s ability to pay the cash portion of Preferential Dividends without the consent of holders owning a majority of the outstanding shares of Series A Preferred Stock. If, in any year, the Corporation fails to make any portion of the cash portion of any Preferential Dividend by the Preferential Dividend Payment Date, then, during the following year, the Corporation may not, without the consent of the holders of a majority of the outstanding shares of Series A Preferred Stock, pay a cash dividend on the Common Stock until such time as the Corporation has paid the cash portion of the Preferential Dividend Payment for such following year (which cash portion of the Preferential Dividend Payment may be paid by the Corporation in advance of the Preferential Dividend Payment Date for, and at any time during, such following year); for the avoidance of doubt, the restrictions set forth in this sentence shall not apply to any non-pro rata purchase, repurchase, or redemption of any equity securities of the Corporation or any of its subsidiaries. As long as shares of Series A Preferred Stock are issued and outstanding, during the occurrence and continuance of a default by the Corporation to pay any Preferential

6

Dividend (for the avoidance of doubt, the payment of any cash portion of the Preferential Dividend in kind in accordance with the terms of this Certificate shall not constitute a default by the Corporation), the approval of holders owning a majority of the outstanding shares of Series A Preferred Stock shall be required (i) for the declaration of dividends to the benefit of all other classes or series of Shares issued and outstanding and (ii) for the purchase, repurchase, or redemption of any equity securities of the Corporation or any of its subsidiaries (other than pursuant to equity incentive agreements with employees).

(f) Shares of Series A Preferred Stock are not entitled to vote on any matter, save for the matters provided for by the DGCL and in this Certificate. Shares of Series A Preferred Stock, being non-voting Shares, shall not be included for the calculation of the quorum and majority at each meeting of stockholders, save for the matters provided for by the DGCL and in this Certificate.

(g) The rights, powers, preferences (or the qualifications, limitations, or restrictions thereof), or other terms of the Series A Preferred Stock pursuant to this Certificate shall not be amended in a manner adverse to the Series A Preferred Stock without the consent of the holders of a majority of the outstanding shares of Series A Preferred Stock.

(h) In the event of any liquidation or winding up of the Corporation, after payment of all the debts of and charges against the Corporation and of the expenses of such liquidation or winding up, the holders of Series A Preferred Stock, if any, shall be entitled to a preferential right to repayment of the then-current Stated Value of the shares of Series A Preferred Stock, plus any accrued but unpaid Preferential Dividends, before any payment is made to the holders of Common Stock.

(i) For purposes of this Article V(B)(2), the following terms shall have the following meanings:

(1) “Person” means any individual, corporation, partnership, joint venture, association, company, joint-stock company, trust, unincorporated organization, limited liability company (or series thereof), or governmental agency or political subdivision thereof or any other entity.

(2) “Redemption Date” means:

(i) in respect of any redemption pursuant to Article V(B)(2)(a)(6), the Maturity Date; and

(ii) in respect of any redemption pursuant to Article V(B)(2)(a)(7), the date set by the Corporation as the date on which such redemption shall occur and subject to extension until the satisfaction, or waiver by the Corporation, of any conditions precedent.

(3) “Redemption Price” means, with respect to any share of Series A Preferred Stock at any Redemption Date, an amount equal to the sum of (A) the then-current Stated Value of such Series A Preferred Stock being redeemed as of such Redemption Date and (B) all accrued and unpaid Preferential Dividends on such Series A Preferred Stock from, and including, the last Preferential Dividend Payment Date to, but excluding, the Redemption Date.

(4) “Series A Holder” means, as of a particular time, any Person that, as of such time, is the holder of record of at least one share of the Series A Preferred Stock.

(5) “Stated Value” means, at any date of determination, and with respect to each outstanding share of the Series A Preferred Stock, the sum of (a) $[ 🌑 ]¹, plus (b) all Preferential Dividends thereon compounded in accordance with Article V(B)(2)(d) as of the immediately preceding Preferential Dividend Payment Date.

ARTICLE VI

For the management of the business and for the conduct of the affairs of the Corporation it is further provided that:

A. The Board of Directors shall be composed of not less than three members (the “directors”), who need not be stockholders of the Corporation. The directors shall each serve for a term of one year. Each director shall hold office until his or her successor is duly elected and qualified or until his or her earlier death, resignation, disqualification, or removal. No decrease in the number of directors shall shorten the term of any incumbent director.

B. Except as otherwise expressly provided by the DGCL or this Certificate, the business and affairs of the Corporation shall be managed by or under the direction of the Board of Directors. The number of directors that shall constitute the whole Board of Directors shall be fixed exclusively by one or more resolutions adopted from time to time by the Board of Directors.

C. Subject to the special rights of the holders of one or more outstanding series of Preferred Stock to elect directors, the Board of Directors or any individual director may be removed from office at any time, with or without cause, by the affirmative vote of the holders of at least a majority of the voting power of the outstanding Shares that are entitled to vote on such matter.

D. Subject to the rights of the holders of one or more outstanding series of Preferred Stock to elect directors, except as otherwise provided by law, any vacancies on the Board of Directors resulting from death, resignation, disqualification, retirement, removal, or other causes and any newly created directorships resulting from any increase in the number of directors shall be filled exclusively by the affirmative vote of a majority of the directors then in office, even though less than a quorum, or by a sole remaining director, and shall not be filled by the stockholders. Any director appointed in accordance with the preceding sentence shall hold office until the expiration of the term to which such director shall have been appointed or until his or her earlier death, resignation, retirement, disqualification, or removal.

E. Whenever the holders of any one or more series of Preferred Stock issued by the Corporation shall have the right, voting separately as a series or separately as a class with one or more such other series, to elect directors at an annual or special meeting of stockholders, the election, term of office, removal, and other features of such directorships shall be governed by the terms of this Certificate (including any Certificate of Designation). Notwithstanding anything to the contrary in this Article VI, the number of directors that may be elected by the holders of any such series of Preferred Stock shall be in addition to the number fixed pursuant to Article VI.B above, and the total number of directors constituting the whole Board of Directors shall be automatically adjusted accordingly. Except as otherwise provided in the Certificate of Designation(s) in respect of one or more series of Preferred Stock, whenever the holders of any series of Preferred Stock having such right to elect additional directors are divested of such right pursuant to the provisions of such Certificate of Designation(s), the terms of office of all such additional directors elected by the holders of such series of Preferred Stock, or elected to fill any vacancies resulting from the death, resignation, disqualification, or removal of such additional directors, shall forthwith terminate (in which case, each such director thereupon shall cease to be qualified as, and shall cease to be, a director) and the total authorized number of directors of the Corporation shall automatically be reduced accordingly.

F. In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized to adopt, amend, or repeal Bylaws of the Corporation. In addition to any vote of the holders of any class or series of Shares required by applicable law or by this Certificate (including any Certificate of Designation in respect of one or more series of Preferred Stock) or the Bylaws of the Corporation, the adoption, amendment, or repeal of the Bylaws of the Corporation by the stockholders of the Corporation shall require the affirmative vote of the holders of at least two-thirds of the votes validly cast in relation to such matter by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon.

G. The directors of the Corporation need not be elected by written ballot unless the Bylaws so provide.

ARTICLE VII

A. Any action required or permitted to be taken by the stockholders of the Corporation must be effected at an annual or special meeting of the stockholders of the Corporation, and shall not be taken by written consent in lieu of a meeting. Notwithstanding the foregoing, any action required or permitted to be taken by the holders of any series of Preferred Stock, voting separately as a series or separately as a class with one or more other such series, may be taken without a meeting, without prior notice, and without a vote, to the extent expressly so provided by this Certificate or the applicable Certificate of Designation relating to such series of Preferred Stock, if a consent or consents in writing, setting forth the action so taken, shall be signed by the holders of outstanding shares of the relevant series of Preferred 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 entitled to vote thereon were present and voted and shall be delivered to the Corporation in accordance with the applicable provisions of the DGCL.

B. Subject to the special rights of the holders of one or more series of Preferred Stock, special meetings of the stockholders of the Corporation may be called, for any purpose or purposes, at any time only by or at the direction of the Board of Directors and shall not be called by any other person or persons.

ARTICLE VIII

No director or officer of the Corporation shall have any personal liability to the Corporation or its stockholders for monetary damages for any breach of fiduciary duty as a director or officer, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or hereafter may be amended. Any amendment, repeal or modification of this Article VIII, or the adoption of any provision of the Certificate inconsistent with this Article VIII, shall not adversely affect any right or protection of a director or officer of the Corporation with respect to any act or omission occurring prior to such amendment, repeal, modification, or adoption. If the DGCL is amended after approval by the stockholders of this Article VIII to authorize corporate action further eliminating or limiting the personal liability of directors or officers, then the liability of a director or officer of the Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended.

ARTICLE IX

The Corporation shall have the power to provide rights to indemnification and advancement of expenses to its current and former officers, directors, employees, and agents and to any person who is or was serving at the request of the Corporation as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise.

ARTICLE X

Unless the Corporation consents in writing to the selection of an alternative forum, (a) the Court of Chancery (the “Chancery Court”) of the State of Delaware (or, in the event that the Chancery Court does not have jurisdiction, the federal district court for the District of Delaware or other state courts of the State of Delaware) shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action, suit, or proceeding brought on behalf of the Corporation, (ii) any action, suit, or proceeding asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, or stockholder of the Corporation to the Corporation or to the Corporation’s stockholders, (iii) any action, suit, or proceeding arising pursuant to any provision of the DGCL or the Bylaws of the Corporation or this Certificate (as either may be amended from time to time) or (iv) any action, suit, or proceeding asserting a claim against the Corporation

9

governed by the internal affairs doctrine; and (b) subject to the preceding provisions of this Article X, the federal district courts of the United States of America shall be the exclusive forum for the resolution of any complaint asserting a cause or causes of action arising under the Securities Act of 1933, as amended, including all causes of action asserted against any defendant to such complaint.

Any person or entity purchasing or otherwise acquiring any interest in any security of the Corporation shall be deemed to have notice of and consented to this Article X. This Article X is intended to benefit and may be enforced by the Corporation, its officers and directors, the underwriters to any offering giving rise to such complaint, and any other professional or entity whose profession gives authority to a statement made by that person or entity and who has prepared or certified any part of the documents underlying the offering. Notwithstanding the foregoing, the provisions of this Article X shall not apply to suits brought to enforce any liability or duty created by the Securities Exchange Act of 1934, as amended, or any other claim for which the federal courts of the United States have exclusive jurisdiction.

If any provision or provisions of this Article X shall be held to be invalid, illegal, or unenforceable as applied to any circumstance for any reason whatsoever, (a) the validity, legality, and enforceability of such provisions in any other circumstance and of the remaining provisions of this Article X (including, without limitation, each portion of any paragraph of this Article X containing any such provision held to be invalid, illegal, or unenforceable that is not itself held to be invalid, illegal, or unenforceable) shall not in any way be affected or impaired thereby and (b) the application of such provision to other persons or entities and circumstances shall not in any way be affected or impaired thereby.

B. If any provision or provisions of this Certificate shall be held to be invalid, illegal or unenforceable as applied to any circumstance for any reason whatsoever: (i) the validity, legality and enforceability of such provisions in any other circumstance and of the remaining provisions of this Certificate (including, without limitation, each portion of any paragraph of this Certificate containing any such provision held to be invalid, illegal or unenforceable that is not itself held to be invalid, illegal or unenforceable) shall not, to the fullest extent permitted by applicable law, in any way be affected or impaired thereby and (ii) to the fullest extent permitted by applicable law, the provisions of this Certificate (including, without limitation, each such portion of any paragraph of this Certificate containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to permit the Corporation to protect its directors, officers, employees and agents from personal liability in respect of their good faith service to or for the benefit of the Corporation to the fullest extent permitted by law.

2.4 Notice of Business to be Brought Before a Meeting.

(a) At an annual meeting of the stockholders, only such business shall be conducted as shall have been properly brought before the meeting. To be properly brought before an annual meeting, business must be (i) specified in a notice of meeting (or supplement thereto) given by or at the direction of the Board of Directors (or authorized committee thereof), (ii) if not specified in a notice of meeting, otherwise brought before the meeting by or at the direction of the Board of Directors (or authorized committee thereof) or a Chairman of the Board or (iii) otherwise properly brought before the meeting by a stockholder present in person who (A) (1) was a record owner of shares of capital stock of the Corporation both at the time of giving the notice provided for in this Section 2.4 and at the time of the meeting, (2) is entitled to vote at the meeting, and (3) has complied with this Section 2.4 in all applicable respects or (B) properly made such proposal in accordance with Rule 14a-8 under the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (as so amended and inclusive of such rules and regulations, the “Exchange Act”). The foregoing clause (iii) shall be the exclusive means for a stockholder to propose business to be brought before an annual meeting of the stockholders. The only matters that may be brought before a special meeting are the matters specified in the notice of meeting given by or at the direction of the person calling the meeting pursuant to Section 2.3 hereof, and stockholders shall not be permitted to propose business to be brought before a special meeting of the stockholders. For purposes of this Section 2.4, “present in person” shall mean that the stockholder proposing that the business be brought before the annual meeting of stockholders of the Corporation, or a qualified representative of such proposing stockholder, appear at such annual meeting, either in person or by means of remote communication. A “qualified representative” of such proposing stockholder shall be a duly authorized officer, manager or partner of such stockholder or any other person authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at or before the annual meeting of stockholders in writing or by electronic communication. Stockholders seeking to nominate persons for election to the Board of Directors must comply with Sections 2.5 and 2.6 of these Bylaws and this Section 2.4 shall not be applicable to nominations except as expressly provided in Sections 2.5 and 2.6 of these Bylaws.

To be timely, a stockholder’s notice must be delivered to, or mailed and received at, the principal executive offices of the Corporation not less than 90 days nor more than 120 days prior to the one-year anniversary of the preceding year’s annual meeting, which, in the case of the first annual meeting of stockholders following the effective time of the Domestication (as defined in the Certificate of Incorporation), the date of the preceding year’s annual meeting shall be deemed to be May 23, 2024; provided, however, that if the date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, notice by the stockholder to be timely must be so delivered, or mailed and received, not more than the 120^th day prior to such annual meeting and not later than (i) the 90^th day prior to such annual meeting or, (ii) if later, the tenth day following the day on which public disclosure of the date of such annual meeting was first made by the Corporation (such notice within such time periods, “Timely Notice”). In no event shall any adjournment or postponement of an annual meeting or the announcement thereof commence a new time period or extend a time period for the giving of Timely Notice as described above.

(c) To be in proper form for purposes of this Section 2.4, a stockholder’s notice to the Secretary shall set forth:

(i) As to each Proposing Person (as defined below), (A) the name and address of such Proposing Person (including, if applicable, the name and address that appear on the Corporation’s books and records), (B) the class or series and number of shares of capital stock of the Corporation that are, directly or indirectly,

2

(ii) As to each Proposing Person, (A) the material terms and conditions of any “derivative security” (as such term is defined in Rule 16a-1(c) under the Exchange Act) that constitutes a “call equivalent position” (as such term is defined in Rule 16a-1(b) under the Exchange Act) or a “put equivalent position” (as such term is defined in Rule 16a-1(h) under the Exchange Act) or other derivative or synthetic arrangement in respect of any class or series of shares of capital stock of the Corporation (“Synthetic Equity Position”) that is, directly or indirectly, held or maintained by, held for the benefit of, or involving such Proposing Person, including, without limitation, (1) any option, warrant, convertible security, stock appreciation right, future or similar right with an exercise or conversion privilege or a settlement payment or mechanism at a price related to any class or series of shares of capital stock of the Corporation or with a value derived in whole or in part from the value of any class or series of shares of capital stock of the Corporation, (2) any derivative or synthetic arrangement having the characteristics of a long position or a short position in any class or series of shares of capital stock of the Corporation, including, without limitation, a stock loan transaction, a stock borrowing transaction, or a share repurchase transaction or (3) any contract, derivative, swap or other transaction or series of transactions designed to (x) produce economic benefits and risks that correspond substantially to the ownership of any class or series of shares of capital stock of the Corporation, (y) mitigate any loss relating to, reduce the economic risk (of ownership or otherwise) of, or manage the risk of share price decrease in, any class or series of shares of capital stock of the Corporation, or (z) increase or decrease the voting power in respect of any class or series of shares of capital stock of the Corporation held or maintained by, held for the benefit of, or involving such Proposing Person; including, without limitation, due to the fact that the value of such contract, derivative, swap or other transaction or series of transactions is determined by reference to the price, value or volatility of any class or series of shares of capital stock of the Corporation, whether or not such instrument, contract or right shall be subject to settlement in the underlying class or series of shares of capital stock of the Corporation, through the delivery of cash or other property, or otherwise, and without regard to whether the holder thereof may have entered into transactions that hedge or mitigate the economic effect of such instrument, contract or right, or any other direct or indirect opportunity to profit or share in any profit derived from any increase or decrease in the price or value of any shares of any class or series of shares of capital stock of the Corporation; provided that, for the purposes of the definition of “Synthetic Equity Position,” the term “derivative security” shall also include any security or instrument that would not otherwise constitute a “derivative security” as a result of any feature that would make any conversion, exercise or similar right or privilege of such security or instrument becoming determinable only at some future date or upon the happening of a future occurrence, in which case the determination of the amount of securities into which such security or instrument would be convertible or exercisable shall be made assuming that such security or instrument is immediately convertible or exercisable at the time of such determination; and, provided, further, that any Proposing Person satisfying the requirements of Rule 13d-1(b)(1) under the Exchange Act (other than a Proposing Person that so satisfies Rule 13d-1(b)(1) under the Exchange Act solely by reason of Rule 13d-1(b)(1)(ii)(E)) shall not be deemed to hold or maintain the notional amount of any securities that underlie any Synthetic Equity Position that is, directly or indirectly, held or maintained by, held for the benefit of, or involving such Proposing Person as a hedge with respect to a bona fide derivatives trade or position of such Proposing Person arising in the ordinary course of such Proposing Person’s business as a derivatives dealer, (B) a description of any agreement, arrangement, or understanding with respect to any rights to dividends on the shares of any class or series of shares of capital stock of the Corporation owned beneficially by such Proposing Person that are separated or separable pursuant to such agreement, arrangement or understanding from the underlying shares of capital stock of the Corporation, (C) any material pending or threatened legal proceeding in which such Proposing Person is a party or material participant involving the Corporation or any of its officers or directors, or any affiliate of the Corporation, (D) any other material

relationship between such Proposing Person, on the one hand, and the Corporation or any affiliate of the Corporation, on the other hand, (E) any direct or indirect material interest in any material contract or agreement of such Proposing Person with the Corporation or any affiliate of the Corporation (including, in any such case, any employment agreement, collective bargaining agreement or consulting agreement), (F) any proportionate interest in shares of capital stock of the Corporation or a Synthetic Equity Position held, directly or indirectly, by a general or limited partnership, limited liability company or similar entity in which any such Proposing Person (1) is a general partner or, directly or indirectly, beneficially owns an interest in a general partner of such general or limited partnership or (2) is the manager, managing member or, directly or indirectly, beneficially owns an interest in the manager or managing member of such limited liability company or similar entity; (G) a representation that such Proposing Person intends or is part of a group that intends to deliver a proxy statement and/or form of proxy to holders of at least the percentage of the Corporation’s outstanding capital stock required to approve or adopt the proposal or otherwise solicit proxies or votes from stockholders in support of such proposal and (H) any other information relating to such Proposing Person that would be required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies or consents by such Proposing Person in support of the business proposed to be brought before the meeting pursuant to Section 14(a) of the Exchange Act (the disclosures to be made pursuant to the foregoing clauses (A) through (H) are referred to as “Disclosable Interests”);; and

(iii) As to each item of business that the stockholder proposes to bring before the annual meeting, (A) a brief description of the business desired to be brought before the annual meeting, the reasons for conducting such business at the annual meeting and any material interest in such business of each Proposing Person, (B) the text of the proposal or business (including the text of any resolutions proposed for consideration and in the event that such business includes a proposal to amend the Bylaws, the language of the proposed amendment), (C) a reasonably detailed description of all agreements, arrangements and understandings (x) between or among any of the Proposing Persons or (y) between or among any Proposing Person and any other Person or entity (including their names) in connection with the proposal of such business by such stockholder, and (D) any other information relating to such item of business that would be required to be disclosed in a proxy statement or other filing required to be made in connection with solicitations of proxies in support of the business proposed to be brought before the meeting pursuant to Section 14(a) of the Exchange Act; provided, however, that the disclosures required by this Section 2.4(iii) shall not include any disclosures with respect to any broker, dealer, commercial bank, trust company or other nominee who is a Proposing Person solely as a result of being the record owner directed to prepare and submit the notice required by these Bylaws on behalf of a beneficial owner.

For purposes of this Section 2.4, the term “Proposing Person” shall mean (i) the stockholder providing the notice of business proposed to be brought before an annual meeting, (ii) the beneficial owner or beneficial owners, if different, on whose behalf the notice of the business proposed to be brought before the annual meeting is made, and (iii) any participant (as defined in paragraphs (a)(ii)-(vi) of Instruction 3 to Item 4 of Schedule 14A of the Exchange Act) with such stockholder in such solicitation.

(d) The Board of Directors may request that any Proposing Person furnish such additional information as may be reasonably required by the Board of Directors to determine whether any proposed business (other than the nominations of persons for election to the Board of Directors) constitutes a proper matter for stockholder action. Such Proposing Person shall provide such additional information within ten days after it has been requested by the Board of Directors.

(e) A Proposing Person shall update and supplement its notice to the Corporation of its intent to propose business at an annual meeting, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 2.4 shall be true and correct as of the record date for stockholders entitled to vote at the meeting and as of the date that is ten business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary at the principal executive offices of the Corporation not later than five business days after the record date for stockholders entitled to vote at the meeting (in the case of the update and supplement required to be

4

made as of such record date), and not later than eight business days prior to the date for the meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the meeting has been adjourned or postponed) (in the case of the update and supplement required to be made as of ten business days prior to the meeting or any adjournment or postponement thereof). For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these Bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any notice provided by a stockholder, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any proposal or to submit any new proposal, including by changing or adding matters, business or resolutions proposed to be brought before a meeting of the stockholders.

(f) Notwithstanding anything in these Bylaws to the contrary, no business shall be conducted at an annual meeting that is not properly brought before the meeting in accordance with this Section 2.4. The Board of Directors prior to the meeting or the presiding officer or chairperson of the meeting shall, if the facts warrant, determine that the business was not properly brought before the meeting in accordance with this Section 2.4, and if he or she should so determine, he or she shall so declare to the meeting and any such business not properly brought before the meeting shall not be transacted.

(g) This Section 2.4 is expressly intended to apply to any business proposed to be brought before an annual meeting of stockholders other than any proposal made in accordance with Rule 14a-8 under the Exchange Act and included in the Corporation’s proxy statement. In addition to the requirements of this Section 2.4 with respect to any business proposed to be brought before an annual meeting, each Proposing Person shall comply with all applicable requirements of the Exchange Act with respect to any such business. Nothing in this Section 2.4 shall be deemed to affect the rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.

(h) For purposes of these Bylaws, “public disclosure” shall mean disclosure in a press release reported by a national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Sections 13, 14 or 15(d) of the Exchange Act.

2.5 Notice of Nominations for Election to the Board of Directors.

(a) Nominations of any person for election to the Board of Directors at an annual meeting or at a special meeting (but only if the election of directors is a matter specified in the notice of meeting given by or at the direction of the person calling such special meeting) may be made at such meeting only (i) by or at the direction of the Board of Directors, including by any committee or persons authorized to do so by the Board of Directors or these Bylaws, or (ii) by a stockholder present in person who (A) was a record owner of shares of capital stock of the Corporation both at the time of giving the notice provided for in this Section 2.5 and at the time of the meeting, (B) is entitled to vote at the meeting, and (C) has complied with this Section 2.5 and Section 2.6 as to such notice and nomination. For purposes of this Section 2.5, “present in person” shall mean that the stockholder nominating any person for election to the Board of Directors at the meeting of the Corporation, or a qualified representative of such stockholder, appear at such meeting, either in person or by means of remote communication to present the nomination. A “qualified representative” of such proposing stockholder shall be a duly authorized officer, manager or partner of such stockholder or any other person authorized by a writing executed by such stockholder or an electronic transmission delivered by such stockholder to act for such stockholder as proxy at the meeting of stockholders and such person must produce such writing or electronic transmission, or a reliable reproduction of the writing or electronic transmission, at or before the meeting of stockholders in writing or by electronic transmission. The foregoing clause (ii) shall be the exclusive means for a stockholder to make any nomination of a person or persons for election to the Board of Directors at an annual meeting or special meeting.

(b) (i) Without qualification, for a stockholder to make any nomination of a person or persons for election to the Board of Directors at an annual meeting, the stockholder must (1) provide Timely Notice (as defined in

To be timely, a stockholder’s notice for nominations to be made at a special meeting must be delivered to, or mailed and received at, the principal executive offices of the Corporation not earlier than the 120^th day prior to such special meeting and not later than the 90^th day prior to such special meeting or, if later, the tenth day following the day on which public disclosure (as defined in Section 2.4) of the date of such special meeting at which directors are to be elected was first made by the Corporation (such notice within such time periods, “Special Meeting Timely Notice”).

(iii) In no event shall any adjournment or postponement of an annual meeting or special meeting or the announcement thereof commence a new time period or extend a time period for the giving of a stockholder’s notice as described above.

(iv) In no event may a Nominating Person provide Timely Notice or Special Meeting Timely Notice, as applicable, with respect to a greater number of director candidates than are subject to election by stockholders at the applicable meeting. If the Corporation shall, subsequent to such notice, increase the number of directors subject to election at the meeting, such notice as to any additional nominees shall be due on the later of (i) the conclusion of the time period for Timely Notice or Special Meeting Timely Notice, as applicable, or (ii) the tenth day following the date of public disclosure of such increase.

(c) To be in proper form for purposes of this Section 2.5, a stockholder’s notice to the Secretary shall set forth:

(i) As to each Nominating Person, the Stockholder Information (as defined in Section 2.4(c)(i), except that for purposes of this Section 2.5 the term “Nominating Person” shall be substituted for the term “Proposing Person” in all places it appears in Section 2.4(c)(i));

(ii) As to each Nominating Person, any Disclosable Interests (as defined in Section 2.4(c)(ii), except that for purposes of this Section 2.5 the term “Nominating Person” shall be substituted for the term “Proposing Person” in all places it appears in Section 2.4(c)(ii) and the disclosure with respect to the business to be brought before the meeting in Section 2.4(c)(ii) shall be made with respect to the nomination of persons for election to the Board to be brought before the meeting); and provided that, in lieu of including the information set forth in Section 2.4(c)(ii)(g), the Nominating Person’s notice for purposes of this Section 2.5 shall include a representation as to whether the Nominating Person intends or is part of a group which intends to deliver a proxy statement and solicit the holders of shares representing at least 67% of the voting power of shares entitled to vote on the election of directors in support of director nominees other than the Corporation’s nominees in accordance with Rule 14a-19 promulgated under the Exchange Act; and

(iii) As to each candidate whom a Nominating Person proposes to nominate for election as a director, (A) all information relating to such candidate for nomination that is required to be disclosed in a proxy statement or other filings required to be made in connection with solicitations of proxies for election of directors in a contested election pursuant to Section 14(a) under the Exchange Act (including such candidate’s written consent

6

to being named in a proxy statement and accompanying proxy card relating to the Corporation’s next meeting of stockholders at which directors are to be elected and to serving as a director for a full term if elected), (B) a description of any direct or indirect material interest in any material contract or agreement between or among any Nominating Person, on the one hand, and each candidate for nomination or his or her respective associates (as defined in Rule 14a-1(a) promulgated under the Exchange Act) or any other participants (as defined in paragraphs (a)(ii) through (vi) of Instruction 3 of Item 4 of Schedule 14A) in such solicitation, on the other hand, including, without limitation, all information that would be required to be disclosed pursuant to Item 404 under Regulation S-K if such Nominating Person were the “registrant” for purposes of such rule and the candidate for nomination were a director or executive officer of such registrant (the disclosures to be made pursuant to the foregoing clauses (A) and (B) are referred to as “Nominee Information”), and (C) a completed and signed questionnaire, representation and agreement as provided in Section 2.6(a).

For purposes of this Section 2.5 and Section 2.6, the term “Nominating Person” shall mean (i) the stockholder providing the notice of the nomination proposed to be made at the meeting, (ii) the beneficial owner or beneficial owners, if different, on whose behalf the notice of the nomination proposed to be made at the meeting is made, and (iii) any participant (as defined in paragraphs (a)(ii)-(vi) in Instruction 3 to Item 4 of Schedule 14A) with such stockholder in such solicitation.

(d) The Board of Directors may request that any Nominating Person furnish such additional information as may be reasonably required by the Board of Directors to determine whether any proposed nominee is qualified or otherwise eligible to serve as a director and/or independent director of the Corporation. Such Nominating Person shall provide such additional information within ten days after it has been requested by the Board of Directors.

(e) A stockholder providing notice of any nomination proposed to be made at a meeting shall further update and supplement such notice or the materials delivered pursuant to this Section 2.5, as applicable, if necessary, so that the information provided or required to be provided in such notice pursuant to this Section 2.5 shall be true and correct as of the record date for stockholders entitled to vote at the meeting and as of the date that is ten business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary at the principal executive offices of the Corporation not later than five business days after the record date for stockholders entitled to vote at the meeting (in the case of the update and supplement required to be made as of such record date), and not later than eight business days prior to the date for the meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the meeting has been adjourned or postponed) (in the case of the update and supplement required to be made as of ten business days prior to the meeting or any adjournment or postponement thereof). For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these Bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any notice provided by a stockholder, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any nomination, including by changing or adding nominees, to submit any new nomination, or to submit any new proposal, matters, business, or resolutions proposed to be brought before a meeting of the stockholders.

(f) In addition to the requirements of this Section 2.5 with respect to any nomination proposed to be made at a meeting, each Nominating Person shall comply with all applicable requirements of the Exchange Act with respect to any such nominations. Notwithstanding the foregoing provisions of this Section 2.5, unless otherwise required by law, (i) no Nominating Person shall solicit proxies in support of director nominees other than the Corporation’s nominees unless such Nominating Person has, or is part of a group that has, complied with Rule 14a-19 promulgated under the Exchange Act in connection with the solicitation of such proxies, including the provision to the Corporation of notices required thereunder, in accordance with the time periods required by this Section 2.5 or by Rule 14a-19 promulgated under the Exchange Act, as applicable, and (ii) if (1) any Nominating Person provides notice in accordance with Rule 14a-19(b) promulgated under the Exchange Act and (2) (x) such notice in accordance with Rule 14a-19(b) is not provided within the time period of Timely Notice or

7

Special Meeting Timely Notice, as applicable, and (y) such Nominating Person subsequently fails to comply with the requirements of Rule 14a-19(a)(2) or Rule 14a-19(a)(3) promulgated under the Exchange Act, or (z) such Nominating Person fails to timely provide reasonable evidence sufficient to satisfy the Corporation that such Nominating Person has met the requirements of Rule 14a-19(a)(3) promulgated under the Exchange Act in accordance with the following sentence, then the nomination of such Nominating Person’s proposed nominees shall be disregarded, notwithstanding that each such nominee is included as a nominee in the Corporation’s proxy statement, notice of meeting or other proxy materials for any annual meeting (or any supplement thereto) and notwithstanding that proxies or votes in respect of the election of such proposed nominees may have been received by the Corporation (which proxies and votes shall be disregarded). If any Nominating Person provides notice in accordance with to Rule 14a-19(b) promulgated under the Exchange Act, such Nominating Person shall deliver to the Corporation, no later than seven business days prior to the applicable meeting, reasonable evidence that it has met the requirements of Rule 14a-19(a)(3) promulgated under the Exchange Act.

2.6 Additional Requirements for Valid Nomination of Candidates to Serve as Director and, if Elected, to be Seated as Directors.

(a) To be eligible to be a candidate for election as a director of the Corporation at an annual or special meeting, a candidate must be nominated in the manner prescribed in Section 2.5 and the candidate for nomination, whether nominated by the Board of Directors or by a stockholder of record, must have previously delivered (in the case of a nomination by a stockholder of record, in accordance with the time periods set forth in Section 2.5), to the Secretary at the principal executive offices of the Corporation, (i) a completed written questionnaire (in the form provided by the Corporation upon written request of any stockholder of record therefor) with respect to the background, qualifications, stock ownership and independence of such proposed nominee and (ii) a written representation and agreement (in the form provided by the Corporation upon written request of any stockholder of record therefor) that such candidate for nomination (A) is not and, if elected as a director during his or her term of office, will not become a party to (1) any agreement, arrangement or understanding with, and has not given and will not give any commitment or assurance to, any person or entity as to how such proposed nominee, if elected as a director of the Corporation, will act or vote on any issue or question (a “Voting Commitment”) or (2) any Voting Commitment that could limit or interfere with such proposed nominee’s ability to comply, if elected as a director of the Corporation, with such proposed nominee’s fiduciary duties under applicable law, (B) is not, and will not become a party to, any agreement, arrangement or understanding with any person or entity other than the Corporation with respect to any direct or indirect compensation or reimbursement for service as a director that has not been disclosed therein or to the Corporation, (C) if elected as a director of the Corporation, will comply with all applicable corporate governance, conflict of interest, confidentiality, stock ownership and trading and other policies and guidelines of the Corporation applicable to directors and in effect during such person’s term in office as a director (and, if requested by any candidate for nomination, the Secretary of the Corporation shall provide to such candidate for nomination all such policies and guidelines then in effect), and (D) if elected as a director of the Corporation, intends to serve the entire term until the next meeting at which such candidate would face re-election.

(b) The Board of Directors may also require any proposed candidate for nomination as a director to furnish such other information as may reasonably be requested by the Board of Directors in writing prior to the meeting of stockholders at which such candidate’s nomination is to be acted upon and related to such candidate’s qualification or eligibility to serve as a director and/or independent director of the Corporation. Without limiting the generality of the foregoing, the Board of Directors may request such other information in order for the Board of Directors to determine the qualification of such candidate for nomination to be an independent director of the Corporation or to comply with the director qualification standards and additional selection criteria in accordance with the Corporation’s Corporate Governance Guidelines. Such other information shall be delivered to, or mailed and received by, the Secretary at the principal executive offices of the Corporation (or any other office specified by the Corporation in any public announcement) not later than five business days after the request by the Board of Directors has been delivered to, or mailed and received by, the Nominating Person.

8

(c) A candidate for nomination as a director by a stockholder pursuant to Section 2.5(b) shall further update and supplement the materials delivered pursuant to this Section 2.6, if necessary, so that the information provided or required to be provided pursuant to this Section 2.6 shall be true and correct as of the record date for stockholders entitled to vote at the meeting and as of the date that is ten business days prior to the meeting or any adjournment or postponement thereof, and such update and supplement shall be delivered to, or mailed and received by, the Secretary at the principal executive offices of the Corporation (or any other office specified by the Corporation in any public announcement) not later than five business days after the record date for stockholders entitled to vote at the meeting (in the case of the update and supplement required to be made as of such record date), and not later than eight business days prior to the date for the meeting or, if practicable, any adjournment or postponement thereof (and, if not practicable, on the first practicable date prior to the date to which the meeting has been adjourned or postponed) (in the case of the update and supplement required to be made as of ten business days prior to the meeting or any adjournment or postponement thereof). For the avoidance of doubt, the obligation to update and supplement as set forth in this paragraph or any other Section of these Bylaws shall not limit the Corporation’s rights with respect to any deficiencies in any notice provided by a stockholder, extend any applicable deadlines hereunder or enable or be deemed to permit a stockholder who has previously submitted notice hereunder to amend or update any nomination or to submit any new proposal, including by changing or adding nominees, matters, business or resolutions proposed to be brought before a meeting of the stockholders.

(d) No candidate proposed to be nominated by a stockholder in accordance with these Bylaws shall be eligible for nomination as a director of the Corporation unless such candidate for nomination and the Nominating Person seeking to place such candidate’s name in nomination has complied with Section 2.5 and this Section 2.6, as applicable. The Board of Directors prior to the meeting or the presiding officer or chairperson at the meeting shall, if the facts warrant, determine that a nomination was not properly made in accordance with Section 2.5 and this Section 2.6, and if he or she should so determine, he or she shall so declare such determination to the meeting, the defective nomination shall be disregarded and any ballots cast for the candidate in question (but in the case of any form of ballot listing other qualified nominees, only the ballots cast for the nominee in question) shall be void and of no force or effect.

(e) Notwithstanding anything in these Bylaws to the contrary, no candidate for nomination shall be eligible to be seated as a director of the Corporation unless nominated and elected in accordance with Section 2.5 and this Section 2.6.

2.7 Notice of Stockholders’ Meetings.

Unless otherwise provided by law, the Certificate of Incorporation or these Bylaws, the notice of any meeting of stockholders shall be sent or otherwise given in accordance with Section 8.1 of these Bylaws not less than ten nor more than sixty days before the date of the meeting to each stockholder entitled to vote at such meeting. The notice shall specify the place, if any, date and time of the meeting, the means of remote communication, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called.

2.8 Quorum.

Unless otherwise provided by law, the Certificate of Incorporation or these Bylaws, the presence, in person, or by remote communication, if applicable, or represented by proxy, of the holders of a majority in voting power of the stock issued and outstanding and entitled to vote at the meeting, shall constitute a quorum for the transaction of business at all meetings of the stockholders.

A quorum, once established at a meeting, shall not be broken by the withdrawal of enough votes to leave less than a quorum. If, however, a quorum is not present or represented at any meeting of the stockholders, then either (i) the person presiding over the meeting or (ii) a majority in voting power of the stockholders entitled to

9

vote thereon, present in person, or by remote communication, if applicable, or represented by proxy, shall have power to recess the meeting or adjourn the meeting from time to time in the manner provided in Section 2.9 of these Bylaws until a quorum is present or represented. At any recessed or adjourned meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the meeting as originally noticed.

2.9 Adjourned Meeting; Notice.

When a meeting is adjourned to another time or place, unless these Bylaws otherwise require, notice need not be given of the adjourned meeting if the time, place, if any, thereof, and the means of remote communications, if any, by which stockholders and proxy holders may be deemed to be present in person and vote at such adjourned meeting are announced at the meeting at which the adjournment is taken or are provided in any other manner permitted by the DGCL. At any adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 30 days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for determination of stockholders entitled to vote is fixed for the adjourned meeting, the Board shall fix as the record date for determining stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote at the adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such meeting as of the record date so fixed for notice of such adjourned meeting.

2.10 Conduct of Business.

The date and time of the opening and the closing of the polls for each matter upon which the stockholders will vote at a meeting shall be announced at the meeting by the person presiding over the meeting. The Board may adopt by resolution such rules and regulations for the conduct of the meeting of stockholders as it shall deem appropriate. Except to the extent inconsistent with such rules and regulations as adopted by the Board, the person presiding over any meeting of stockholders shall have the right and authority to convene and (for any or no reason) to recess and/or adjourn the meeting, to prescribe such rules, regulations and procedures (which need not be in writing) and to do all such acts as, in the judgment of such presiding person, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board or prescribed by the person presiding over the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present (including, without limitation, rules and procedures for removal of disruptive persons from the meeting); (iii) limitations on attendance at or participation in the meeting to stockholders entitled to vote at the meeting, their duly authorized and constituted proxies or such other persons as the person presiding over the meeting shall determine; (iv) restrictions on entry to the meeting after the time fixed for the commencement thereof; and (v) limitations on the time allotted to questions or comments by participants. The presiding person at any meeting of stockholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting (including, without limitation, determinations with respect to the administration and/or interpretation of any of the rules, regulations or procedures of the meeting, whether adopted by the Board or prescribed by the person presiding over the meeting), shall, if the facts warrant, determine and declare to the meeting that a matter of business was not properly brought before the meeting and if such presiding person should so determine, such presiding person shall so declare to the meeting and any such matter or business not properly brought before the meeting shall not be transacted or considered. Unless and to the extent determined by the Board or the person presiding over the meeting, meetings of stockholders shall not be required to be held in accordance with the rules of parliamentary procedure.

2.11 Voting.

Except as may be otherwise provided in the Certificate of Incorporation or the DGCL, each stockholder shall be entitled to one vote for each share of capital stock held by such stockholder.

10

Except as otherwise provided by the Certificate of Incorporation, at all duly called or convened meetings of stockholders at which a quorum is present, for the election of directors, a simple majority of the votes cast shall be sufficient to elect a director. Except as otherwise provided by the Certificate of Incorporation, these Bylaws, the rules or regulations of any stock exchange applicable to the Corporation, or applicable law or pursuant to any regulation applicable to the Corporation or its securities, each other matter presented to the stockholders at a duly called or convened meeting at which a quorum is present shall be decided by the a majority of the votes cast (excluding abstentions and broker non-votes) on such matter.

2.12 Record Date for Stockholder Meetings and Other Purposes.

In order that the Corporation may determine the stockholders entitled to notice of any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board, and which record date shall, unless otherwise required by law, not be more than 60 days nor less than ten days before the date of such meeting. If the Board so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the close of business on the next day preceding the day on which notice is first given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting; and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance herewith at the adjourned meeting.

In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of capital stock, or for the purposes of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

Unless otherwise restricted by the Certificate of Incorporation, in order that the Corporation may determine the stockholders entitled to express consent to corporate action without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than ten days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. If no record date for determining stockholders entitled to express consent to corporate action without a meeting is fixed by the Board of Directors, (i) when no prior action of the Board of Directors is required by law, the record date for such purpose shall be the first date on which a signed consent setting forth the action taken or proposed to be taken is delivered to the Corporation in accordance with applicable law, and (ii) if prior action by the Board of Directors is required by law, the record date for such purpose shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

2.13 Proxies.

Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy authorized by an instrument in writing or by a transmission permitted by law, including Rule 14a-19 promulgated under the Securities Exchange Act of 1934, as amended, filed in accordance with the procedure established for the meeting, but no such proxy shall be voted or acted upon after three years

11

from its date, unless the proxy provides for a longer period. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the provisions of Section 212 of the DGCL. A proxy may be in the form of an electronic transmission which sets forth or is submitted with information from which it can be determined that the transmission was authorized by the stockholder.

Any stockholder directly or indirectly soliciting proxies from other stockholders must use a proxy card color other than white, which shall be reserved for the exclusive use by the Board.

2.14 List of Stockholders Entitled to Vote.

The Corporation shall prepare, no later than the tenth day before each meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting (provided, however, that if the record date for determining the stockholders entitled to vote is less than ten days before the date of the meeting, the list shall reflect the stockholders entitled to vote as of the tenth day before the meeting date), arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder. The Corporation shall not be required to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of ten days ending on the day before the meeting date: (i) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (ii) during ordinary business hours, at the Corporation’s principal executive office. In the event that the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. Such list shall presumptively determine the identity of the stockholders entitled to vote at the meeting and the number of shares held by each of them. Except as otherwise provided by law, the stock ledger shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 2.14 or to vote in person or by proxy at any meeting of stockholders.

2.15 Inspectors of Election.

Before any meeting of stockholders, the Corporation shall appoint an inspector or inspectors of election to act at the meeting or its adjournment and make a written report thereof. The Corporation may designate one or more persons as alternate inspectors to replace any inspector who fails to act. If any person appointed as inspector or any alternate fails to appear or fails or refuses to act, then the person presiding over the meeting shall appoint a person to fill that vacancy.

Such inspectors shall:

(a) determine the number of shares outstanding and the voting power of each, the number of shares represented at the meeting and the validity of any proxies and ballots;

(b) count all votes or ballots;

(c) count and tabulate all votes;

(d) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspector(s); and

(e) certify its or their determination of the number of shares represented at the meeting and its or their count of all votes and ballots.

Each inspector, before entering upon the discharge of the duties of inspector, shall take and sign an oath faithfully to execute the duties of inspection with strict impartiality and according to the best of such inspector’s

12

ability. Any report or certificate made by the inspectors of election is prima facie evidence of the facts stated therein. The inspectors of election may appoint such persons to assist them in performing their duties as they determine.

2.16 Delivery to the Corporation.

Other than as specified by Section 2.13, whenever this Article II requires one or more persons (including a record or beneficial owner of stock) to deliver a document or information to the Corporation or any officer, employee or agent thereof (including any notice, request, questionnaire, revocation, representation or other document or agreement), such document or information shall be in writing exclusively (and not in an electronic transmission) and shall be delivered exclusively by hand (including, without limitation, overnight courier service) or by certified or registered mail, return receipt requested, and the Corporation shall not be required to accept delivery of any document not in such written form or so delivered. For the avoidance of doubt, the Corporation expressly opts out of Section 116 of the DGCL with respect to the delivery of information and documents to the Corporation required by this Article  II.

Article III - Directors

Except as otherwise provided by the Certificate of Incorporation or the DGCL, the business and affairs of the Corporation shall be managed by or under the direction of the Board.

3.2 Number of Directors.

Subject to the Certificate of Incorporation, the total number of directors constituting the Board shall be determined from time to time by only resolution of the Board.

3.3 Election, Qualification and Term of Office of Directors.

Except as provided in Section 3.4 of these Bylaws, and subject to the Certificate of Incorporation, each director, including a director elected to fill a vacancy or newly created directorship, shall hold office until the expiration of the term of the class, if any, for which elected and until such director’s successor is elected and qualified or until such director’s earlier death, resignation, disqualification or removal. Directors need not be stockholders. The Certificate of Incorporation or these Bylaws may prescribe qualifications for directors.

3.4 Resignation and Vacancies.

Any director may resign at any time upon notice given in writing or by electronic transmission to the Corporation. The resignation shall take effect at the time specified therein or upon the happening of an event specified therein, and if no time or event is specified, at the time of its receipt. When one or more directors so resigns and the resignation is effective at a future date or upon the happening of an event to occur on a future date, a majority of the directors then in office, including those who have so resigned, shall have power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become effective, and each director so chosen shall hold office as provided in Section 3.3.

Unless otherwise provided in the Certificate of Incorporation or these Bylaws, vacancies resulting from the death, resignation, disqualification or removal of any director, and newly created directorships resulting from any increase in the authorized number of directors shall be filled only by a majority of the directors then in office, although less than a quorum, or by a sole remaining director.

13

3.5 Place of Meetings; Meetings by Telephone

The Board may hold meetings, both regular and special, either within or outside the State of Delaware.

Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, members of the Board, or any committee designated by the Board, may participate in a meeting of the Board, or any committee, by means of conference telephone or other communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in a meeting pursuant to this bylaw shall constitute presence in person at the meeting.

Regular meetings of the Board may be held either within or outside the State of Delaware and at such time and at such place, if any, as which has been designated by the Board and publicized among all directors, either orally or in writing, by telephone, including a voice-messaging system or other system designed to record and communicate messages, facsimile, telegraph or telex, or by electronic mail or other means of electronic transmission. No further notice shall be required for regular meetings of the Board.

If the notice is (i) delivered personally by hand, by courier or by telephone, (ii) sent by facsimile or electronic mail, or (iii) sent by other means of electronic transmission, it shall be delivered or sent at least 24 hours before the time of the holding of the meeting.

3.8 Quorum.

At all meetings of the Board, unless otherwise provided by the Certificate of Incorporation or applicable laws or regulations, a majority of the total number of directors shall constitute a quorum for the transaction of business. The vote of a majority of the directors present at any meeting at which a quorum is present shall be the act of the Board, except as may be otherwise specifically provided by the DGCL, the Certificate of Incorporation or these Bylaws.

14

3.9 Board Action without a Meeting.

Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board, or of any committee thereof, may be taken without a meeting if all members of the Board or committee, as the case may be, consent thereto in writing or by electronic transmission. After an action is taken, the consent or consents relating thereto shall be filed with the minutes of the proceedings of the Board, or the committee thereof, in the same paper or electronic form as the minutes are maintained. Such action by written consent or consent by electronic transmission shall have the same force and effect as a unanimous vote of the Board.

3.10 Fees and Compensation of Directors.

Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, the Board shall have the authority to fix the compensation, including fees and reimbursement of expenses, of directors for services to the Corporation in any capacity.

The Board may designate one or more committees, each committee to consist, of one or more of the directors of the Corporation. The Board may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. In the absence or disqualification of a member of a committee, the member or members thereof present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board to act at the meeting in the place of any such absent or disqualified member. Any such committee, to the extent provided in the resolution of the Board or in these Bylaws, and to the extent permitted by applicable law, shall have and may exercise all the powers and authority of the Board in the management of the business and affairs of the Corporation, and may authorize the seal of the Corporation to be affixed to all papers that may require it; but no such committee shall have the power or authority to (i) approve or adopt, or recommend to the stockholders, any action or matter expressly required by the DGCL to be submitted to stockholders for approval (other than the election or removal of directors), or (ii) adopt, amend or repeal any bylaw of the Corporation.

(i) the time of regular meetings of committees may be determined either by resolution of the Board or by resolution of the committee;

(ii) special meetings of committees may also be called by resolution of the Board or the chairperson of the applicable committee; and

Subject to the rights, if any, of an officer under any contract of employment, any officer may be removed, either with or without cause, by the Board or, except in the case of an officer chosen by the Board, by any officer upon whom such power of removal may be conferred by the Board.

17

authority may be general or confined to specific instances. Unless so authorized or ratified by the Board or within the agency power of an officer, or as set forth herein (including pursuant to Section 5.7 and Section 7.2), no officer, agent or employee shall have any power or authority to bind the Corporation by any contract or engagement or to pledge its credit or to render it liable for any purpose or for any amount.

Every holder of stock represented by a certificate shall be entitled to have a certificate signed by, or in the name of the Corporation by, any two officers authorized to sign stock certificates representing the number of shares registered in certificate form. A Chairperson or Vice Chairperson of the Board, Chief Executive Officer, the President, Vice President, the Treasurer, any Assistant Treasurer, the Secretary or any Assistant Secretary of the Corporation shall be specifically authorized to sign stock certificates. Any or all of the signatures on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate has ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he or she were such officer, transfer agent or registrar at the date of issue.

The Corporation may issue the whole or any part of its shares as partly paid and subject to call for the remainder of the consideration to be paid therefor. Upon the face or back of each stock certificate issued to represent any such partly paid shares, or upon the books and records of the Corporation in the case of uncertificated partly paid shares, the total amount of the consideration to be paid therefor and the amount paid thereon shall be stated. Upon the declaration of any dividend on fully paid shares, the Corporation shall declare a dividend upon partly paid shares of the same class, but only upon the basis of the percentage of the consideration actually paid thereon.

If the Corporation is authorized to issue more than one class of stock or more than one series of any class, then the powers, the designations, the preferences and the relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights shall be set forth in full or summarized on the face or on the back of the certificate that the Corporation shall issue to represent such class or series of stock (or, in the case of uncertificated shares, set forth in a notice provided pursuant to Section 151 of the DGCL); provided, however, that except as otherwise provided in Section 202 of the DGCL, in lieu of the foregoing requirements, there may be set forth on the face of back of the certificate that the Corporation shall issue to represent such class or series of stock (or, in the case of any uncertificated shares, included in the aforementioned notice) a statement that the Corporation will furnish without charge to each stockholder who so requests the powers, the designations, the preferences and the relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and/or rights.

7.4 Lost Certificates.

Except as provided in this Section 7.4, no new certificates for shares shall be issued to replace a previously issued certificate unless the latter is surrendered to the Corporation and cancelled at the same time. The Corporation may issue a new certificate of stock or uncertificated shares in the place of any certificate theretofore issued by it, alleged to have been lost, stolen or destroyed, and the Corporation may require the owner of the lost, stolen or destroyed certificate, or such owner’s legal representative, to give the Corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate or uncertificated shares.

18

7.7 Dividends.

The Board, subject to any restrictions contained in either (i) the DGCL or (ii) the Certificate of Incorporation, may declare and pay dividends upon the shares of its capital stock. Dividends may be paid in cash, in property or in shares of the Corporation’s capital stock.

The Board may set apart out of any of the funds of the Corporation available for dividends a reserve or reserves for any proper purpose and may abolish any such reserve. Such purposes shall include but not be limited to equalizing dividends, repairing or maintaining any property of the Corporation, and meeting contingencies.

7.8 Fiscal Year.

The fiscal year of the Corporation shall be fixed by resolution of the Board and may be changed by the Board.

7.9 Seal.

The Corporation may adopt a corporate seal, which shall be adopted and which may be altered by the Board. The Corporation may use the corporate seal by causing it or a facsimile thereof to be impressed or affixed or in any other manner reproduced.

Shares of the Corporation shall be transferable in the manner prescribed by law and in these Bylaws. Shares of stock of the Corporation shall be transferred on the books of the Corporation only by the holder of record thereof or by such holder’s attorney duly authorized in writing, upon surrender to the Corporation of the certificate or certificates representing such shares endorsed by the appropriate person or persons (or by delivery of duly executed instructions with respect to uncertificated shares), with such evidence of the authenticity of such endorsement or execution, transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps. No transfer of stock shall be valid as against the Corporation for any purpose until it shall have been entered in the stock records of the Corporation by an entry showing the names of the persons from and to whom it was transferred.

7.11 Stock Transfer Agreements.

The Corporation shall have power to enter into and perform any agreement with any number of stockholders of any one or more classes or series of stock of the Corporation to restrict the transfer of shares of stock of the Corporation of any one or more classes owned by such stockholders in any manner not prohibited by the DGCL.

19

7.12 Registered Stockholders.

The Corporation:

(a) shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends and to vote as such owner; and

(b) shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of another person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of the State of Delaware.

7.13 Waiver of Notice.

Whenever notice is required to be given under any provision of the DGCL, the Certificate of Incorporation or these Bylaws, a written waiver, signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time of the event for which notice is to be given, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in any written waiver of notice or any waiver by electronic transmission unless so required by the Certificate of Incorporation or these Bylaws.

Article VIII - Notice

8.1 Delivery of Notice; Notice by Electronic Transmission.

Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Corporation under any provisions of the DGCL, the Certificate of Incorporation, or these Bylaws may be given in writing directed to the stockholder’s mailing address (or by electronic transmission directed to the stockholder’s electronic mail address, as applicable) as it appears on the records of the Corporation and shall be given (1) if mailed, when the notice is deposited in the U.S. mail, postage prepaid, (2) if delivered by courier service, the earlier of when the notice is received or left at such stockholder’s address or (3) if given by electronic mail, when directed to such stockholder’s electronic mail address unless the stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail. A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Corporation.

Without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Corporation under any provision of the DGCL, the Certificate of Incorporation or these Bylaws shall be effective if given by a form of electronic transmission (other than email) consented to by the stockholder to whom the notice is given. Any such consent shall be revocable by the stockholder by written notice or electronic transmission to the Corporation. Notwithstanding the provisions of this paragraph, the Corporation may give a notice by electronic mail in accordance with the first paragraph of this section without obtaining the consent required by this paragraph.

Any notice given pursuant to the preceding paragraph shall be deemed given:

(a) if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice;

(b) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of (A) such posting and (B) the giving of such separate notice; and

(c) if by any other form of electronic transmission, when directed to the stockholder.

20

Notwithstanding the foregoing, a notice may not be given by an electronic transmission from and after the time that (1) the Corporation is unable to deliver by such electronic transmission two (2) consecutive notices given by the Corporation and (2) such inability becomes known to the Secretary or an Assistant Secretary of the Corporation or to the transfer agent, or other person responsible for the giving of notice, provided, however, the inadvertent failure to discover such inability shall not invalidate any meeting or other action.

An affidavit of the Secretary or an Assistant Secretary or of the transfer agent or other agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

Article IX - Indemnification

9.1 Indemnification of Directors and Officers.

The Corporation shall indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any director or officer of the Corporation who was or is made or is threatened to be made a party or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (a “Proceeding”) by reason of the fact that he or she is or was a director or officer of the Corporation or, while serving as a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses (including attorneys’ fees, judgments, fines ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred by such person in connection with any such Proceeding.

9.2 Indemnification of Others.

The Corporation shall have the power to indemnify and hold harmless, to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended, any employee or agent of the Corporation who was or is made or is threatened to be made a party or is otherwise involved in any Proceeding by reason of the fact that he or she is or was an employee or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust, enterprise or non-profit entity, including service with respect to employee benefit plans, against all liability and loss suffered and expenses reasonably incurred by such person in connection with any such Proceeding.

The Corporation shall to the fullest extent permitted by applicable law pay the expenses (including attorneys’ fees) incurred by any officer or director of the Corporation, and may pay the expenses incurred by any employee or agent of the Corporation, in defending any Proceeding in advance of its final disposition; provided, however, that such payment of expenses in advance of the final disposition of the Proceeding shall be made only upon receipt of an undertaking by the person to repay all amounts advanced if it should be ultimately determined that the person is not entitled to be indemnified under this Article IX or otherwise.

9.4 Determination; Claim.

If a claim for indemnification (following the final disposition of such Proceeding) under this Article IX is not paid in full within 60 days, or a claim for advancement of expenses under this Article IX is not paid in full within 30 days, after a written claim therefor has been received by the Corporation the claimant may thereafter

21

(but not before) file suit to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim to the fullest extent permitted by law. In any such action the Corporation shall have the burden of proving that the claimant was not entitled to the requested indemnification or payment of expenses under applicable law.

9.5 Non-Exclusivity of Rights.

The rights conferred on any person by this Article IX shall not be exclusive of any other rights which such person may have or hereafter acquire under any statute, provision of the Certificate of Incorporation, these Bylaws, agreement, vote of stockholders or disinterested directors or otherwise.

9.7 Other Indemnification.

The Corporation’s obligation, if any, to indemnify or advance expenses to any person who was or is serving at its request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust, enterprise or non-profit entity shall be reduced by any amount such person may collect as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, enterprise or non-profit enterprise.

9.8 Continuation of Indemnification.

The rights to indemnification and to prepayment of expenses provided by, or granted pursuant to, this Article IX shall continue notwithstanding that the person has ceased to be a director or officer of the Corporation and shall inure to the benefit of the estate, heirs, executors, administrators, legatees and distributees of such person.

9.9 Amendment or Repeal; Interpretation.

The provisions of this Article IX shall constitute a contract between, on the one hand, the Corporation and, on the other hand, each individual who serves or has served as a director, officer, employee, or agent of the Corporation (whether before or after the adoption of these Bylaws), in consideration of such person’s performance of such services, and pursuant to this Article IX the Corporation intends to be legally bound to each such current or former director, officer, employee, or agent of the Corporation. With respect to current and former directors, officers, employees, or agents of the Corporation, the rights conferred under this Article IX are present contractual rights and such rights are fully vested, and shall be deemed to have vested fully, immediately upon adoption of theses Bylaws. With respect to any directors, officers, employees, or agents of the Corporation who commence service following adoption of these Bylaws, the rights conferred under this Section 9.9 shall be present contractual rights and such rights shall fully vest, and be deemed to have vested fully, immediately upon such director, officer, employee, or agent commencing service as a director or officer of the Corporation. Any repeal or modification of the foregoing provisions of this Article IX shall not adversely affect any right or protection (i) hereunder of any person in respect of any act or omission occurring prior to the time of such repeal or modification or (ii) under any agreement providing for indemnification or advancement of expenses to a director, officer, employee, or agent of the Corporation in effect prior to the time of such repeal or modification.
