This proposal shall be referred to as the “NTA Proposal”;

The Proposed Business Combination

On January 22, 2024, the Company (or “CSLM”), a Cayman Islands exempted company (which, pursuant to the terms of the Merger Agreement (as defined below), shall de-register from the Register of Companies in the Cayman Islands by way of continuation out of the Cayman Islands and into the State of Delaware so as to migrate to and domesticate as a Delaware corporation prior at least one Business Day prior to the Closing Date, entered into a Merger Agreement (as it may be amended and/or restated from time to time, the “Merger Agreement”), by and among CSLM, CSLM Merger Sub Inc., a Delaware corporation and a direct, wholly owned subsidiary of CSLM (“Merger Sub”), and Fusemachines Inc., a Delaware corporation (“Fusemachines” or the “Target”).

Fusemachines is a global provider of enterprise Artificial Intelligence (“AI”) products and solutions on a mission to democratize AI, by providing high quality AI education in underserved communities and helping organizations achieve their full potential with AI.

Under the Merger Agreement, the Fusemachines securityholders will receive an aggregate number of CSLM Common Shares equal to the quotient obtained by dividing (a) $200,000,000, by (b) US$10.00 in exchange for all of Fusemachines’s Aggregate Fully Diluted Company Common Stock, as such terms are defined in the Merger Agreement.

Prior Extension.

On July 13, 2023 as approved by its shareholders at an extraordinary general meeting, the Company’s Existing Charter was amended by a special resolution approved by the shareholders, and provides that the Sponsor (as hereinafter defined) has the right to cause the Company to extend the period of time to consummate a business combination (the “Combination Period”) on a month-to-month basis, until October 18, 2024 by depositing $70,000 (each an “Extension Payment”) into the Trust Account for each one-month extension. In connection with this extraordinary general meeting, 14,202,813 Public Shares were tendered for redemption, leaving 4,772,187 Public Shares outstanding.

On July 13, 2023, the Company issued an aggregate of 4,743,749 shares of its Class A Shares to Consilium Acquisition Sponsor I, LLC, the Company’s sponsor (the “Sponsor”) and the holder of the Company’s Class B ordinary shares, par value $0.0001 per share (“Class B Shares”), upon the conversion of an equal number of Class B Shares (the “Conversion”). The 4,743,749 Class A Shares issued in connection with the Conversion are subject to the same restrictions as applied to the Class B Shares before the Conversion, including, among other things, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial business combination as described in the prospectus for our initial public offering (the converted Class B Shares and the remaining one Class B Share are together referred to as the “Sponsor Shares”).

Following the Conversion and the redemptions, there were 9,515,936 Class A Shares issued and outstanding and one Class B Share issued and outstanding.

Holders of the Sponsor Shares have agreed to waive their respective rights to liquidating distributions from the trust account in respect of any Sponsor Shares held by it or them, as applicable, if the company fails to complete an initial business combination.

The Sponsor has indicated that if the Extension Proposal is approved, the Sponsor will contribute $   , as a loan to the Company (each loan being referred to herein as a “Contribution”) for each one-month extension period, commencing on the 18th day of each month, (each such one-month extension, an “Extension Period”) until the earlier of (x) the date of the extraordinary general meeting held in connection with a shareholder vote to approve its initial business combination; (y) the Extended Date and (z) the date that the board determines in its sole discretion to no longer seek an initial business combination.

The Company intends to deposit each contribution in the Trust Account within three business days of the beginning of the Extension Period which such Contribution relates to. The Sponsor will not make any Contribution unless the Extension Proposal is approved. The Contributions will be repayable by the Company to the Sponsor upon consummation of an initial business combination. The Company’s board of directors will have the sole discretion to extend the timeline to consummate an initial business combination for an additional Extension Period. If the board of directors determines not to extend the timeline to consummate an initial business combination by an additional Extension Period, the additional Contributions will terminate. If the board of directors determines not to extend the timeline to consummate an initial business combination by an additional Extension Period, the Company will cease all operations except for the purpose of winding up and as promptly as reasonably possible, but not more than ten business days after the Current Termination Date, redeem 100% of the outstanding Public Shares in accordance with the procedures set forth in the Existing Charter.

The Contribution will not bear any interest and will be repayable by the Company to Sponsor, or its affiliates or designees, upon consummation of an initial business combination. The loans will be forgiven if the Company is unable to consummate the Proposed Business Combination except to the extent of any funds held outside of the Trust Account. If the Company’s board of directors determines that the Company will not be able to consummate the Proposed Business Combination by the Extended Date, the Company will cease all operations except for the purpose of winding up and as promptly as reasonably possible, but not more than ten business days after the Current Termination Date, redeem 100% of the issued and outstanding Public Shares in accordance with the procedures set forth in the Existing Charter in the event the NTA Proposal, the Extension Proposal and Trust Amendment Proposal are not approved.

Your attention is directed to the proxy statement accompanying this Notice for a more complete statement of matters to be considered at the General Meeting.

The Company’s board of directors has fixed the close of business on         , 2024 as the record date for determining the Company’s shareholders entitled to receive notice of and to vote at the General Meeting and any adjournment or postponement thereof. Only holders of record of the Ordinary Shares and Public Shares on that date are entitled to have their votes counted at the General Meeting or any adjournment or postponement thereof.

To exercise your redemption rights, you must tender your shares to the Company’s transfer agent at least two business days prior to the General Meeting (or    , 2024). You may tender your shares by either delivering your share certificate to the transfer agent or by delivering your shares electronically using the Depository Trust Company’s DWAC (Deposit/Withdrawal At Custodian) system. If you hold your shares in street name, you will need to instruct your bank, broker or other nominee to withdraw the shares from your account in order to exercise your redemption rights.

After careful consideration of all relevant factors, the Company’s board of directors recommends that you vote or give instructions to vote (i) “FOR” the NTA Proposal; (ii) “FOR” the Extension Proposal; (iii) “FOR” the Trust Amendment Proposal, (iv) “FOR” the Financial Statements Proposal, and if presented (v) “FOR” the Adjournment Proposal. Notwithstanding the order of the resolutions on the notice to the General Meeting, the Adjournment Proposal may be presented first to the shareholders if, based on the tabulated vote collected at the time of the General Meeting, there are insufficient votes for, or otherwise in connection with, the approval of the NTA Proposal, the Extension Proposal, the Financial Statements Proposal and the Trust Amendment Proposal.

Enclosed is the proxy statement containing detailed information concerning the NTA Proposal, the Extension Proposal, the Trust Amendment Proposal, the Financial Statements Proposal the Adjournment Proposal and the General Meeting.

Whether or not you plan to virtually attend the General Meeting, we urge you to read this material carefully and vote your shares.

I look forward to seeing you at the meeting.

Your vote is important. Please sign, date and return your proxy card as soon as possible but in any event so as to be received by Advantage Proxy prior to the commencement of the General Meeting to make sure that your shares are represented at the General Meeting. If you are a shareholder of record, you may also cast your vote in person (including virtually) at the General Meeting. If your shares are held in an account at a brokerage firm or bank, you must instruct your broker or bank how to vote your shares, or you may cast your vote in person (including virtually) at the General Meeting by obtaining a proxy from your brokerage firm or bank. Your failure to vote or instruct your broker or bank how to vote will have no effect on the outcome of the proposals.

PROXY STATEMENT

CSLM ACQUISITION CORP., (the “Company,” “CSLM,” “we,” “us” or “our”), a Cayman Islands exempted company, is providing this proxy statement in connection with the solicitation by the Company’s board of directors (the “Board”) of proxies to be voted at the General Meeting to be held 10:00 a.m. ET on August [18], 2024. The physical place of the meeting will be held at 2400 E. Commercial Boulevard, Suite 900, Ft. Lauderdale, FL 33308. For more information please visit https://www.cstproxy.com/cimspac/2024.

This meeting shall also serve as the Company’s annual meeting of shareholders for the year 2024.

The Company has identified a potential business combination target company (the “Target”) for an initial business combination (the “Proposed Business Combination”). The Company believes the Target is a compelling opportunity for the Company’s initial business combination and is currently in the process of completing an initial business combination involving the Target.

The purpose of the Extension Proposal is to allow the Company more time to complete its Proposed Business Combination.

The Company will also be holding the General Meeting via teleconference using the following dial-in information:

Conference ID: 587 621 6464

The General Meeting will be held for the sole purpose of considering and voting upon:

1

In addition, our board of directors currently believes that there will not be sufficient time before the Current Termination Date to complete the Proposed Business Combination and hold an extraordinary general meeting at which to conduct a vote for shareholder approval of the Proposed Business Combination. Accordingly, our board of directors has determined it is in the best interests of the Company to extend the termination date from the Current Termination Date to the Extended Date.

If the Extension Proposal is not approved at the General Meeting or any adjournment or postponement thereof and we do not consummate a business combination by the Current Termination Date, we will (a) cease all operations except for the purpose of winding up, (b) as promptly as reasonably possible but not more than five business days thereafter, redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay incomes taxes, if any, (less up to US$100,000 of interest to pay dissolution expenses), divided by the number of then Public Shares in issue, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), and (c) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in the case of paragraph (b) and (c), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases, subject to the other requirements of applicable law.

The Board has fixed the close of business on       , 2024 as the record date for determining the Company’s shareholders entitled to receive notice of and to vote at the General Meeting and any adjournment thereof (the “Record Date”). On the Record Date, there were 9,515,936 Class A ordinary shares and one Class B Share, issued and outstanding. The Company’s rights and warrants do not have voting rights. Only holders of record of the Company’s Ordinary Shares on the Record Date are entitled to have their votes counted at the General Meeting or any adjournment thereof.

We are soliciting proxies so that each shareholder has an opportunity to vote on all matters that are scheduled to come before the shareholders at the General Meeting. Whether or not you plan to attend, please take the time now to read the proxy statement and vote by submitting by mail a paper copy of your proxy or vote instructions, so that your shares are represented at the General Meeting.

QUESTIONS AND ANSWERS ABOUT THE GENERAL MEETING

These Questions and Answers are only summaries of the matters they discuss. They do not contain all of the information that may be important to you. You should carefully read the entire document, including the annexes to this proxy statement.

4

The purpose of the Extension Proposal is to allow the Company more time to complete its proposed business combination (the “Proposed Business Combination”).

Our board of directors currently believes that there will not be sufficient time before the Current Termination Date to complete its Proposed Business Combination and hold a general meeting at which to conduct a vote for shareholder approval of the Proposed Business Combination. Accordingly, our board of directors has determined it is in the best interests of the Company to extend the termination date from the Current Termination Date to the Extended Date.

If the Extension Proposal is not approved at the General Meeting or any adjournment or postponement thereof and we do not consummate a business combination by the Current Termination Date, assuming that the time to complete a business combination is not extended as provided in the Existing Charter, we will (a) cease all operations except for the purpose of winding up, (b) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay income taxes, if any, (less up to US$100,000 of interest to pay dissolution expenses), divided by the number of then Public Shares in issue, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), and (c) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, liquidate and dissolve, in the case of paragraph (b) and (c), subject to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases, subject to the other requirements of applicable law.

YOU ARE NOT BEING ASKED TO VOTE ON THE BUSINESS COMBINATION AT THIS TIME. IF THE NTA PROPOSAL, EXTENSION PROPOSAL AND TRUST AMENDMENT PROPOSAL ARE APPROVED AND THE EXTENSION AMENDMENT IS FILED AND YOU DO NOT ELECT TO REDEEM YOUR PUBLIC SHARES NOW, YOU WILL RETAIN THE RIGHT TO VOTE ON THE BUSINESS COMBINATION WHEN IT IS SUBMITTED TO SHAREHOLDERS AND THE RIGHT TO REDEEM YOUR PUBLIC SHARES FOR A PRO RATA PORTION OF THE TRUST ACCOUNT IN THE EVENT THE BUSINESS COMBINATION IS APPROVED AND COMPLETED OR THE COMPANY HAS NOT CONSUMMATED A BUSINESS COMBINATION BY THE EXTENDED DATE.

In addition, the purpose of the NTA Proposal, is to ensure that, in connection with its Proposed Business Combination, the Company would continue, as it has since the IPO, to be not subject to the “penny stock” rules of the SEC, and therefore not a “blank check company” as defined under Rule 419 of the Securities Act because it complied with Rule 3a51-1(g)(1) (the “NTA Rule”). The Company is proposing to amend its Existing Charter to remove the requirement that the Company have net tangible assets of at least $5,000,001

5

to consummate a Business Combination. The NTA Rule is one of several exclusions from the “penny stock” rules of the SEC and the Company believes that it may rely on another exclusion, which relates to it being listed on the Nasdaq Global Market (Rule 3a51-1(a)(2)) (the “Exchange Rule”), to not be deemed a penny stock issuer by being listed on Nasdaq Capital or Global Market. If the NTA Proposal is approved, the Company will not be required to maintain net tangible assets in order to complete the Proposed Business Combination.

Accordingly, we believe that the NTA Proposal, the Extension Proposal and the Trust Amendment Proposal are consistent with the spirit in which the Company offered its securities to the public in the IPO.

You will have redemption rights in connection with the NTA Proposal, the Extension Proposal and The Trust Amendment Proposal.

If the NTA Proposal, the Extension Proposal and the Trust Amendment Proposal are approved, with respect to holders’ right to redeem, the Company will remove from the Trust Account an amount (the “Withdrawal Amount”) equal to the pro rata portion of funds available in the Trust Account relating to any Public Shares redeemed by holders in connection with the NTA Proposal, the Extension Proposal and the Trust Amendment Proposal, if any, and (ii) deliver to the holders of such redeemed Public Shares their pro rata portion of the Withdrawal Amount. The remainder of such funds shall remain in the Trust Account and be available for use by the Company to complete the Proposed Business Combination or a potential alternative initial business combination on or before the Extended Date. Holders of Public Shares who do not redeem their Public Shares now will retain their redemption rights and their ability to vote on the Proposed Business Combination or a potential alternative initial business combination.

6

Our Initial Shareholders, including our Sponsor, our officers and directors and the representative in our initial public offering, are not entitled to redeem such shares in connection with the Extension Proposal. On the Record Date, they held 4,743,750 Ordinary Shares (which includes one Class B Share) representing approximately 49% of the Company’s issued and outstanding Ordinary Shares.

The Company’s initial shareholders did not beneficially own any Public Shares in the aggregate as of the Record Date but may choose to purchase Public Shares in the open market and/or through negotiated private transactions after the date of this proxy statement. In the event that such purchases do occur, the initial shareholders may seek to purchase shares from shareholders who would otherwise have voted against the NTA Proposal, Extension Proposal and Trust Amendment Proposal and/or elected to redeem their shares. Any Public Shares so purchased will be voted in favor of the NTA Proposal, the Extension Proposal and Trust Amendment Proposal.

Extension Proposal. The Extension Proposal must be approved by a special resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a majority of not less than two- thirds of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote in person or by proxy at the General Meeting of the Company, of which notice specifying the intention to propose the resolution as a special resolution has been duly given.

Trust Amendment Proposal. The Trust Amendment Proposal must be approved by a special resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of not less than two-thirds of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote in person or by proxy at the General Meeting of the Company of which notice specifying the intention to propose the resolution as a special resolution has been duly given.

Financial Statements Proposal. The Financial Statements Proposal must be approved by an ordinary resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a simple majority of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote in person or by proxy at the General Meeting of the Company of which notice specifying the intention to propose the resolution as a special resolution has been duly given.

Adjournment Proposal. The Adjournment Proposal must be approved by an ordinary resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a simple majority of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote, in person or by proxy, at the General Meeting of the Company.

7

The amount in the Trust Account (less approximately $1,897.50 representing the aggregate nominal par value of the shares issued in the IPO) under the Companies Act will be treated as a share premium which is distributable under the Companies Act, provided that immediately following the date on which the proposed distribution is proposed to be made, we are able to pay our debts as they fall due in the ordinary course of business. If we are forced to liquidate the Trust Account, we anticipate that we would distribute to holders of the Public Shares issued in the IPO (the “Public Shareholders”) the amount in the Trust Account calculated as of the date that is two days prior to the distribution date (including any accrued interest). Prior to such distribution, we would be required to assess all claims that may be potentially brought against us by our creditors for amounts they are actually owed and make provision for such amounts, as creditors take priority over our Public Shareholders with respect to amounts that are owed to them. We cannot assure you that we will properly assess all claims that may be potentially brought against us. As such, our shareholders could potentially be liable for any claims of creditors to the extent of distributions received by them as an unlawful payment in the event we enter an insolvent liquidation. Furthermore, while we will seek to have all vendors and service providers (which would include any third parties we engaged to assist us in any way in connection with our search for a target business) and prospective target businesses execute agreements with us waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account, there is no guarantee that they will execute such agreements. Nor is there any guarantee that, even if such entities execute such agreements with us, they will not seek recourse against the Trust Account or that a court would conclude that such agreements are legally enforceable.

The Initial Shareholders have agreed to waive their rights to participate in any liquidation of our Trust Account or other assets with respect to the 4,743,750 Ordinary Shares held or controlled by our Initial Shareholders prior to the IPO (the “insider shares”) and to vote their insider shares in favor of any dissolution and plan of distribution which we submit to a vote of shareholders. There will be no distribution from the Trust Account with respect to the insider shares.

8

If the Extension Proposal is approved, the removal of the Withdrawal Amount from the Trust Account, if any, will reduce the amount remaining in the Trust Account and increase the percentage interest of Company shares held by the Company’s officers, directors and their affiliates.

NTA Proposal. The NTA Proposal must be approved by a special resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a majority of not less than two- thirds of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote in person or by proxy at the General Meeting of the Company, of which notice specifying the intention to propose the resolution as a special resolution has been duly given.

Extension Proposal. The Extension Proposal must be approved by a special resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a majority of not less than two-thirds of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote, in person or by proxy, at the General Meeting of the Company, of which notice specifying the intention to propose the resolution as a special resolution has been duly given.

Trust Amendment Proposal. The Trust Amendment Proposal must be approved by a special resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a majority of not less than two-thirds of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote, in person or by proxy, at the General Meeting of the Company, of which notice specifying the intention to propose the resolution as a special resolution has been duly given.

Financial Statements Proposal. The Financial Statements Proposal must be approved by an ordinary resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a simple majority of the votes cast by the holders of the then issued and outstanding Ordinary Shares and Public Shares, voting together as one class by such shareholders as, being entitled to do so, vote, in person or by proxy, at a the General Meeting of the Company.

Adjournment Proposal. The Adjournment Proposal must be approved by an ordinary resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a simple majority of the votes cast by the holders of the then issued and outstanding Ordinary Shares and Public Shares, voting together as one class by such shareholders as, being entitled to do so, vote, in person or by proxy, at a the General Meeting of the Company.

Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast and will have no effect on the proposals. As a result, if you abstain from voting on any of the proposals, your shares will be counted as present for purposes of establishing a quorum (if so present in accordance with the terms of our Existing Charter), but the abstention will have no effect on the outcome of such proposal.

Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast and will have no effect on the Proposals. As a result, if you abstain from voting on any of the Proposals, your shares will be counted as present for purposes of establishing a quorum (if so present in accordance with the terms of the Existing Charter), but the abstention will have no effect on the outcome of such proposal.

If a shareholder who holds share in “street name” does not give the broker voting instructions, the broker is not permitted under applicable self-regulatory organization rules to vote the shares on “non-routine” proposals, such as the NTA Proposal and the Extension Proposal. These “broker non-votes” will also count as present for purposes of determining whether a quorum is present and will have no effect on the outcome of the vote on any of the Proposals.

BACKGROUND

The Company

The Company is a blank check company incorporated in the Cayman Islands as an exempted company. We were incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or similar business combination with one or more businesses, which we refer to as our initial business combination.

On January 18, 2022, the Company consummated the IPO of 18,975,000 units at a price of $10.00 per public unit, including the full exercise of the underwriter’s overallotment option, generating gross proceeds of $189,750,000. Substantially concurrently with the closing of the IPO, the Company consummated a private placement of 7,942,500 warrants, at a price of $1.00 per private placement warrant to the Sponsor (the “Private Warrants”), generating gross proceeds of $7,942,500.

Upon the closing of the IPO and the underwriters’ exercise of the over-allotment option, and associated private placement, 191,647,500 ($10.10 per unit) of cash was placed in the Trust Account with Continental Stock Transfer & Trust Company acting as trustee established for the benefit of the persons holding Public Shares.

On July 13, 2023 as approved by its shareholders at an extraordinary general meeting, the Company’s Existing Charter was amended by a special resolution approved by the shareholders, and provides that the Sponsor (as hereinafter defined) has the right to cause the Company to extend the period of time to consummate a business combination (the “Combination Period”) on a month-to-month basis, until October 18, by depositing $70,000 (each an “Extension Payment”) into the Trust Account for each one-month extension. In connection with this extraordinary general meeting, 14,202,813 Public Shares were tendered for redemption, leaving 4,772,187 Public Shares outstanding. As of the date of this proxy statement, the Company has until August 18, 2024 (the ”Current Termination Date”) to complete its Proposed Business Combination.

On July 13, 2023, the Company issued an aggregate of 4,743,749 shares of its Class A Shares to Consilium Acquisition Sponsor I, LLC, the Company’s sponsor (the “Sponsor”) and the holder of the Company’s Class B ordinary shares, par value $0.0001 per share (“Class B Shares”), upon the conversion of an equal number of Class B Shares (the “Conversion”). The 4,743,749 Class A Shares issued in connection with the Conversion are subject to the same restrictions as applied to the Class B Shares before the Conversion, including, among other things, certain transfer restrictions, waiver of redemption rights and the obligation to vote in favor of an initial business combination as described in the prospectus for our initial public offering (the converted Class B Shares and the remaining one Class B Share are together referred to as the “Sponsor Shares”).

Following the Conversion and the redemptions, there were 9,515,936 Class A Shares issued and outstanding and one Class B Share issued and outstanding.

Holders of the Sponsor Shares have agreed to waive their respective rights to liquidating distributions from the trust account in respect of any Sponsor Shares held by it or them, as applicable, if the company fails to complete an initial business combination.

The Sponsor has indicated that if the NTA Proposal, the Extension Proposal and the Trust Amendment Proposal are approved, the Sponsor will contribute $    , as a loan to the Company (each loan being referred to herein as a “Contribution”) for each one-month extension period, commencing on the 18th day of each month, (each such one-month extension, an “Extension Period”), until the earlier of (x) the date of the extraordinary general meeting held in connection with a shareholder vote to approve its initial business combination; (y) the Extended Date and (z) the date that the board determines in its sole discretion to no longer seek an initial business combination.

On January 22, 2024, the Company (or “CSLM”), a Cayman Islands exempted company (which shall de- register from the Register of Companies in the Cayman Islands by way of continuation out of the Cayman Islands

15

and into the State of Delaware so as to migrate to and domesticate as a Delaware corporation prior to the closing), entered into a Merger Agreement, by and among CSLM, CSLM Merger Sub Inc., a Delaware corporation and a direct, wholly owned subsidiary of CSLM (“Merger Sub”), and Fusemachines Inc., a Delaware corporation (“Fusemachines” or the “Target”) (as it may be amended and/or restated from time to time, the “Merger Agreement”).

Fusemachines is a global provider of enterprise Artificial Intelligence (“AI”) products and solutions on a mission to democratize AI, by providing high quality AI education in underserved communities and helping organizations achieve their full potential with AI.

Under the Merger Agreement, the Fusemachines securityholders will receive an aggregate of the number of CSLM Common Shares equal to the quotient obtained by dividing (a) $200,000,000, by (b) US$10.00 in exchange for all of Fusemachines’s Aggregate Fully Diluted Company Common Stock, as such term is defined in the Merger Agreement.

PROPOSAL 1

The NTA Proposal

CSLM’s shareholders are being asked to approve and adopt an amendment to the Existing Charter (such amendment, the “NTA Amendment”) to remove the provision of Section 160.(b) which provides that the Company shall not repurchase Public Shares in an amount that would cause the Company’s net tangible assets to be less than US$5,000,001 in order to complete a business combination (“NTA Requirement”).

The Current Section 160 reads as follows:

Prior to the consummation of any Business Combination, the Company shall either:

The NTA Amendment will remove this limitation by deleting the words: “provided that the Company shall not repurchase Public Shares in an amount that would cause the Company’s net tangible assets to be less than US$5,000,001; provided that Shares must only be purchased if the Business Combination to which the opportunity relates is consummated”

Reasons for the Amendment

If the Amendment to the Existing Charter is approved, CSLM will not be subject to the NTA Requirement, and will not be required to maintain net tangible assets in order to complete a Business Combination. Furthermore, the Combined Company is applying for its securities to be listed on the Nasdaq Global Market, so the NTA Requirement will not be necessary.

The purpose of this requirement was to ensure companies would not be subject to the “penny stock” rules of the SEC, and therefore not a “blank check company” as defined under Rule 419 of the Securities Act because it complied with Rule 3a51-1(g)(1) (the “NTA Rule”). This inclusion was to ensure that, in connection with its initial business combination, CSLM would continue, as it has since the IPO, to be not subject to the “penny stock” rules of the SEC, and therefore not a “blank check company” as defined under Rule 419 of the Securities Act because it complied with Rule 3a51-1(g)(1) (the “NTA Rule”). CSLM is proposing to amend its Current Charter to remove the NTA Requirement.

The NTA Rule is one of several exclusions from the “penny stock” rules of the SEC and CSLM believes that it may rely on another exclusion, Rule 3a51-1(a)(2) (the “Exchange Rule”) which excludes from the definition of “penny stock” securities listed on a national securities exchange. CSLM believes that because its securities are currently listed on the Nasdaq Capital Market, it cannot be deemed a penny stock issuer.

Full Text of the Resolution.

Please see Annex A.

Vote Required for Approval

The NTA Proposal must be approved by a special resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a majority of not less than two-thirds of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote, in person or by proxy, at the General Meeting of the Company, of which notice specifying the intention to propose the resolution as a special resolution has been duly given. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast and will have no effect on the NTA Proposal. As a result, if you abstain from voting on the Extension Proposal, your shares will be counted as present for purposes of establishing a quorum (if so present in accordance with the terms of our Existing Charter), but the abstention will have no effect on the outcome of such proposal.

The Sponsor, which includes among its members each of the directors and officers of CSLM, owns 4,743,750 Founder Shares, including the sole outstanding CSLM Class B Ordinary Share. As a result, as of the date of this proxy statement/prospectus, the Insiders own approximately 50% of the issued and outstanding CSLM Ordinary Shares. Accordingly, the votes of holders of 1,603,380 Ordinary Shares will be required to approve the NTA Proposal even if all other outstanding shares are voted against such proposal.

THE BOARD RECOMMENDS A VOTE “FOR” THE NTA PROPOSAL.

PROPOSAL 2

THE EXTENSION PROPOSAL

The Extension Proposal

The Company is proposing to amend its Existing Charter (such amendment, the “Extension Amendment”) to: extend the time to complete the Proposed Business Combination from August 18, 2024 (the “Current Termination Date”), so long as the Sponsor places $    per month into the Company’s Trust Account, up to July 18, 2025 (the “Extended Date”), the date by which, if the Company has not consummated the Proposed Business Combination the Company must: (a) cease all operations except for the purpose of winding up, (b) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the ordinary shares of a par value of US$0.0001 each (the “Ordinary Shares”) issued in the Company’s initial public offering (the “Public Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay incomes taxes, if any, (less up to US$100,000 of interest to pay dissolution expenses), divided by the number of then Public Shares in issue, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), and (c) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in the case of paragraph (b) and (c), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases, subject to the other requirements of applicable law. The Extension Proposal is essential to the overall implementation of the Board’s plan to allow the Company more time to complete the Proposed Business Combination. Approval of the Extension Proposal is a condition to the filing of the Extension Amendment. A copy of the Extension Amendment to the Existing Charter of the Company is attached to this proxy statement as Annex A.

The Company’s Existing Charter provides that the sponsor, Consilium Acquisition Sponsor I, LLC, (the Sponsor”), has the right to cause the Company to extend the period of time to consummate a business combination (the “Combination Period”) on a month-to-month basis until October 18, 2024 by depositing into the Company’s Trust Account $70,000 for each one month extension on the 18th day of each subsequent month, (each such one-month extension, an “Extension Period”), until the earlier of (x) the date of the extraordinary general meeting held in connection with a shareholder vote to approve the Proposed Business Combination; (y) the Current Termination Date, so long as the Sponsor continues to place $70,000 per month into the Company’s Trust Account, and (z) the date that the board determines in its sole discretion to no longer seek the Proposed Business Combination. As of the date of this proxy statement, the Company has until August 18, 2024 (the ”Current Termination Date”) to complete its Proposed Business Combination.

If the Extension Proposal is approved, the Combination Period will be extended on a month-to-month basis from the Current Termination Date until the Extended Date, so long as the Sponsor deposits $     into the Trust Account for each Extension Period, until July 18, 2025. The Company intends to deposit each contribution in the Trust Account within three business days of the beginning of the Extension Period which such Contribution relates to. The Sponsor will not make any Contribution past August 18, 2024 unless the Extension Proposal is approved. The Contributions will be repayable by the Company to the Sponsor upon consummation of the Proposed Business Combination. The Company’s board of directors will have the sole discretion to extend the timeline to consummate the Proposed Business Combination for an additional Extension Period, up to July 18, 2025. If the board of directors determines not to extend the timeline to consummate the Proposed Business Combination by an additional Extension Period, the additional Contributions will terminate. If the board of directors determines not to extend the timeline to consummate the Proposed Business Combination by an additional Extension Period, the Company will cease all operations except for the purpose of winding up and as promptly as reasonably possible, but not more than ten business days after the Current Termination Date, redeem 100% of the outstanding Public Shares in accordance with the procedures set forth in the Existing Charter.

19

The Contribution will not bear any interest and will be repayable by the Company to Sponsor, or its affiliates or designees, upon consummation of the Proposed Business Combination. The loans will be forgiven if the Company is unable to consummate the Proposed Business Combination except to the extent of any funds held outside of the Trust Account. If the Company’s board of directors determines that the Company will not be able to consummate the Proposed Business Combination by the Extended Date, the Company will cease all operations except for the purpose of winding up and as promptly as reasonably possible, but not more than ten business days after the Current Termination Date, redeem 100% of the issued and outstanding Public Shares in accordance with the procedures set forth in the Existing Charter in the event the Extension Proposal and Trust Amendment Proposal are not approved.

All holders of the Company’s Public Shares, whether they vote for or against the Extension Proposal or do not vote at all, will be permitted to redeem all or a portion of their Public Shares at a per-share price, payable in cash, equal to their pro rata portion of the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust Account and not previously released to the Company to pay our income taxes, if any, (less up to $100,000 of interest to pay dissolution expenses), divided by the number of Public Shares then in issue, provided that the Extension Proposal is approved. Holders of Public Shares do not need to be a holder of record on the Record Date in order to exercise redemption rights. If the Extension Proposal is approved but the NTA Proposal is not approved, we will not file for an Extension Period if we do not have net tangible assets of at least $5,000,001.

The per-share price equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust Account and not previously released to the Company to pay our income taxes, if any, (less up to $100,000 of interest to pay dissolution expenses), divided by the number of Public Shares then in issue was approximately $10.48 per Public Share. The closing price of the Company’s Public Shares on       , 2024 was $   . The Company cannot assure Shareholders that they will be able to sell their Public Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such Shareholders wish to sell their shares.

Reasons for the Extension Proposal

The purpose of the Extension Proposal is to allow the Company more time to consummate the Proposed Business Combination. The Company’s IPO prospectus and the Existing Charter provide that the Company has until the Current Termination Date to complete a business combination. While the Company has signed a definitive business combination agreement, our board of directors currently believes that there will not be sufficient time before the Current Termination Date to complete the Proposed Business Combination and hold a general meeting at which to conduct a vote for shareholder approval of the Proposed Business Combination. Accordingly, our board of directors has determined it is in the best interests of the Company to extend the termination date from the Current Termination Date to the Extended Date.

If the Extension Proposal Is Not Approved

If based on the tabulated vote there are insufficient votes to approve the Extension Proposal and the Trust Amendment Proposal, the Company may put the Adjournment Proposal to a vote as the first resolution in order to seek additional time to obtain sufficient votes in support of the Extension Proposal and the Trust Amendment Proposal. If the Extension Proposal and the Trust Amendment are not approved at the General Meeting, we expect to take all necessary actions and hold additional general meetings until October 18, 2024, to obtain the approval of the Extension Proposal and the Trust Amendment Proposal. If the Extension Proposal and the Trust Amendment Proposal are not approved by October 18, 2024 and we are unable to consummate the Proposed Business Combination prior to or on October 18, 2024, assuming that the time to complete a business combination is not extended in accordance with the Existing Charter, the Company shall (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-Share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust Account and not previously released to the Company to pay income taxes, if any, (less up to $100,000 of interest to pay dissolution expenses), divided by the number of Public Shares then in issue, which redemption will completely extinguish public Shareholders’

20

rights as Shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Shareholders and the Directors, liquidate and dissolve, subject in the case of sub-articles (ii) and (iii), to its obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. At such time, the Private Warrants will expire and the Sponsor will receive nothing upon a liquidation with respect to such Private Warrants, and the Private Warrants will be worthless.

The amount in the Trust Account (less approximately $1,897.50 representing the aggregate nominal par value of the shares issued in the IPO) under the Companies Act will be treated as a share premium which is distributable under the Companies Act, provided that immediately following the date on which the proposed distribution is proposed to be made, we are able to pay our debts as they fall due in the ordinary course of business. If we are forced to liquidate the Trust Account, we anticipate that we would distribute to holders of the Public Shares issued in the IPO (the “Public Shareholders”) the amount in the Trust Account calculated as of the date that is two days prior to the distribution date (including any accrued interest). Prior to such distribution, we would be required to assess all claims that may be potentially brought against us by our creditors for amounts they are actually owed and make provision for such amounts, as creditors take priority over our Public Shareholders with respect to amounts that are owed to them. We cannot assure you that we will properly assess all claims that may be potentially brought against us. As such, our shareholders could potentially be liable for any claims of creditors to the extent of distributions received by them as an unlawful payment in the event we enter an insolvent liquidation. Furthermore, while we will seek to have all vendors and service providers (which would include any third parties we engaged to assist us in any way in connection with our search for a target business) and prospective target businesses execute agreements with us waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account, there is no guarantee that they will execute such agreements. Nor is there any guarantee that, even if such entities execute such agreements with us, they will not seek recourse against the Trust Account or that a court would conclude that such agreements are legally enforceable.

Our Initial Shareholders, including our Sponsor, our officers and directors and the representative in our initial public offering, have agreed to waive their rights to participate in any liquidation of our Trust Account or other assets with respect to the insider shares and to vote their insider shares in favor of any dissolution and plan of distribution which we submit to a vote of shareholders. There will be no distribution from the Trust Account with respect to our private warrants, which will expire worthless.

If the Extension Proposal is Approved

If the Extension Proposal is approved, the Company will file an amendment (the “Extension Amendment”) to the Existing Charter with the Registrar of Companies of the Cayman Islands in the form of Annex A hereto to extend the time it has to complete a business combination until the Extended Date. The Company will continue to attempt to consummate the Proposed Business Combination until the Extended Date, or until the Board determines in its sole discretion that it will not be able to consummate the Proposed Business Combination or a potential alternative business combination and does not wish to seek an additional extension. The Company will remain a reporting company under the Securities Exchange Act of 1934 and its Public Shares will remain publicly traded during the extension period.

YOU ARE NOT BEING ASKED TO VOTE ON ANY BUSINESS COMBINATION AT THIS TIME. IF THE EXTENSION PROPOSAL IS APPROVED AND THE EXTENSION AMENDMENT IS FILED AND YOU DO NOT ELECT TO REDEEM YOUR PUBLIC SHARES NOW, YOU WILL RETAIN THE RIGHT TO VOTE ON ANY PROPOSED BUSINESS COMBINATION WHEN AND IF IT IS SUBMITTED TO SHAREHOLDERS AND THE RIGHT TO REDEEM YOUR PUBLIC SHARES FOR A PRO RATA PORTION OF THE TRUST ACCOUNT IN THE EVENT THE PROPOSED BUSINESS COMBINATION IS APPROVED AND COMPLETED.

21

Redemption Rights

If the Extension Proposal is approved, and the Extension Amendment is filed, each Public Shareholder may seek to redeem its Public Shares for a pro rata portion of the funds available in the Trust Account, less any taxes we anticipate will be owed, but have not yet been paid, calculated as of two business days prior to the meeting. Holders of Public Shares do not need to vote on the Extension Proposal or be a holder of record on the Record Date to exercise redemption rights.

If the Extension Proposal is approved, the Company will (i) remove from the Trust Account an amount (the “Withdrawal Amount”) equal to the pro rata portion of funds available in the Trust Account relating to any Public Shares redeemed by holders in connection with the Extension Proposal, if any, and (ii) deliver to the holders of such redeemed Public Shares their pro rata portion of the Withdrawal Amount. The remainder of such funds shall remain in the Trust Account and be available for use by the Company to complete a business combination on or before the Extended Date. Holders of Public Shares who do not redeem their Public Shares now will retain their redemption rights and their ability to vote on a business combination through the Extended Date, if the Extension Proposal is approved and the Extension Amendment is filed.

If the Extension Proposal is approved, and the Extension Amendment is filed, the removal of the Withdrawal Amount from the Trust Account, if any, will reduce the Company’s net asset value. The Company cannot predict the amount that will remain in the Trust Account if the Extension Proposal is approved, and the amount remaining in the Trust Account may be only a small fraction of the approximately $    that was in the Trust Account as of      , 2024.

TO DEMAND REDEMPTION, IF YOU HOLD PHYSICAL CERTIFICATES FOR ORDINARY SHARES, YOU MUST PHYSICALLY TENDER YOUR SHARE CERTIFICATES TO CONTINENTAL STOCK TRANSFER & TRUST COMPANY, THE COMPANY’S TRANSFER AGENT, AT CONTINENTAL STOCK TRANSFER & TRUST COMPANY, ONE STATE STREET PLAZA, 30TH FLOOR, NEW YORK, NY 10004, ATTN: MARK ZIMKIND, E-MAIL: SPACREDEMPTIONS@CONTINENTALSTOCK.COM, NO LATER THAN TWO BUSINESS DAYS PRIOR TO THE GENERAL MEETING. IF YOU HOLD YOUR ORDINARY SHARES IN “STREET NAME” THROUGH A BANK, BROKER OR OTHER NOMINEE, YOU MUST DELIVER YOUR SHARES TO CONTINENTAL STOCK TRANSFER & TRUST COMPANY ELECTRONICALLY USING THE DEPOSITORY TRUST COMPANY’S DWAC (DEPOSIT/ WITHDRAWAL AT CUSTODIAN) SYSTEM TWO BUSINESS DAYS PRIOR TO THE GENERAL MEETING TO DEMAND REDEMPTION.

The requirement for physical or electronic delivery prior to the vote at the General Meeting ensures that a redeeming holder’s election is irrevocable once the Extension Proposal is approved. In furtherance of such irrevocable election, Shareholders making the election will not be able to tender their shares after the vote at the General Meeting.

The electronic delivery process through the DWAC system can be accomplished by the shareholder, whether or not it is a record holder or its shares are held in “street name,” by contacting the transfer agent or its broker and requesting delivery of its shares through the DWAC system. Delivering shares physically may take significantly longer. In order to obtain a physical share certificate, a shareholder’s broker and/or clearing broker, DTC, and the Company’s transfer agent will need to act together to facilitate this request. There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC system.

The transfer agent will typically charge the tendering broker a nominal amount and the broker would determine whether or not to pass this cost on to the redeeming holder. It is the Company’s understanding that shareholders should generally allot at least two weeks to obtain physical certificates from the transfer agent.

22

The Company does not have any control over this process or over the brokers or DTC, and it may take longer than two weeks to obtain a physical share certificate. Such Shareholders will have less time to make their investment decision than those Shareholders that deliver their shares through the DWAC system. Shareholders who request physical share certificates and wish to redeem may be unable to meet the deadline for tendering their shares before exercising their redemption rights and thus will be unable to redeem their shares.

Certificates that have not been tendered in accordance with these procedures prior to the vote for the Extension Proposal will not be redeemed into a pro rata portion of the funds held in the Trust Account. In the event that a Public Shareholder tenders its shares and decides prior to the vote at the General Meeting that it does not want to redeem its shares, the shareholder may withdraw the tender. If you delivered your shares for redemption to our transfer agent and decide prior to the vote at the General Meeting not to redeem your shares, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the address listed above prior to the vote at the General Meeting. In the event that a Public Shareholder tenders shares, and the Extension Proposal is not approved or is abandoned, these shares will be redeemed in accordance with the terms of the Existing Charter promptly following the meeting, as described elsewhere herein. The Company anticipates that a Public Shareholder who tenders shares for redemption in connection with the vote to approve the Extension Proposal would receive payment of the redemption price for such shares soon after the filing of the Extension Proposal. The transfer agent will hold the certificates of Public Shareholders that make the election until such shares are redeemed for cash or redeemed in connection with our winding up.

The per-share pro rata portion of the Trust Account on      , 2024 after taking into account taxes owed but not paid by such date (which is expected to be the same approximate amount two business days prior to the General Meeting) was approximately $    per Public Share. The closing price of the Ordinary Shares on       , 2024 was $   . The Company cannot assure shareholders that they will be able to sell their Public Shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

If you exercise your redemption rights, you will be exchanging your Public Shares for cash and will no longer own the shares. You will be entitled to receive cash for these shares only if you properly demand redemption by tendering your share certificate(s) to the Company’s transfer agent prior to the vote for the Extension Proposal. If the Extension Proposal is not approved or if it is abandoned, these shares will be redeemed in accordance with the terms of the Existing Charter promptly following the meeting as described elsewhere herein.

Required Vote

The Extension Proposal must be approved by a special resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a majority of not less than two-thirds of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote, in person or by proxy, at the General Meeting of the Company, of which notice specifying the intention to propose the resolution as a special resolution has been duly given. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast and will have no effect on the Extension Proposal. As a result, if you abstain from voting on the Extension Proposal, your shares will be counted as present for purposes of establishing a quorum (if so present in accordance with the terms of our Existing Charter), but the abstention will have no effect on the outcome of such proposal.

RISK FACTORS

You should consider carefully all of the risks described in our Annual Report on Form 10-K and our Quarterly Reports on Form 10-Q, and in the other reports we file with the SEC before making a decision to invest in our securities. Furthermore, if any of the following events occur, our business, financial condition and operating results may be materially adversely affected or we could face liquidation. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties described in the aforementioned filings and below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business, financial condition and operating results or result in our liquidation.

We are required by the Nasdaq Listing Rules to consummate a Business Combination within 36 months of the effectiveness of our IPO Registration Statement. In the event we do not consummate a Business Combination within this time period, or securities could be subject to delisting.

Pursuant to IM-5101-2(b) of the Nasdaq Listing Rules, we must consummate a Business Combination within 36 months of the effectiveness of our IPO Registration Statement, or by January 12, 2025. The proposed extension of the Charter Extension Date to July 18, 2025 may extend our ability to complete an Initial Business Combination until the forty-two (42) month anniversary of our IPO, which will take us beyond the permitted period for a business combination under the Nasdaq Listing Rules. If we do not consummate a Business Combination by January 12, 2025, Nasdaq may issue a Staff Delisting Determination under Rule 5810 to delist our securities. If Nasdaq delists our securities from trading on its exchange, we could face significant material adverse consequences, including:

We may not be able to complete the Proposed Business Combination with a U.S. target company since such initial business combination may be subject to U.S. foreign investment regulations and review by a U.S. government entity such as the Committee on Foreign Investment in the United States (CFIUS), or ultimately prohibited.

CSLM’s sponsor, CSLM Acquisition Sponsor I, LLC, a Cayman Islands limited liability company, is controlled by US persons and CSLM’s Chairman, Chief Executive Officer and Chief Financial Officer are also US persons. CSLM has one independent director that resides outside the United States, however, we do not anticipate that he will be affiliated with the company upon completion of a business combination. In addition, the Target for the Business Combination is a US company with US management. For these reasons, we believe that CSLM should not be considered a “foreign person” under the regulations administered by CFIUS and should not be considered as such in the future. However, the Proposed Business Combination with a U.S. business may be subject to CFIUS review, the scope of which was expanded by the Foreign Investment Risk Review Modernization Act of 2018 (“FIRRMA”), to include certain non-passive non-controlling investments in

24

sensitive U.S. businesses and certain acquisitions of real estate even with no underlying U.S. business. FIRRMA, and subsequent implementing regulations that are now in force, also subjects certain categories of investments to mandatory filings. If CSLM’s potential initial business combination with a U.S. business falls within CFIUS’s jurisdiction, CSLM may determine that it is required to make a mandatory filing or that it will submit a voluntary notice to CFIUS, or to proceed with the initial business combination without notifying CFIUS and risk CFIUS intervention, before or after closing the initial business combination. CFIUS may decide to block or delay CSLM’s initial business combination, impose conditions to mitigate national security concerns with respect to such initial business combination or order CSLM to divest all or a portion of a U.S. business of the combined company without first obtaining CFIUS clearance, which may limit the attractiveness of or prevent CSLM from pursuing certain initial business combination opportunities that it believes would otherwise be beneficial to CSLM and its shareholders. As a result, the pool of potential targets with which CSLM could complete the Proposed Business Combination may be limited and it may be adversely affected in terms of competing with other special purpose acquisition companies which do not have similar foreign ownership issues.

Moreover, the process of government review, whether by the CFIUS or otherwise, could be lengthy and CSLM has limited time to complete its initial business combination. If CSLM cannot complete its initial business combination by August 18, 2024 (a later date if CSLM extends the timeline to complete its initial business combination) because the review process drags on beyond such timeframe or because CSLM’s initial business combination is ultimately prohibited by CFIUS or another U.S. government entity, CSLM may be required to liquidate. If CSLM liquidates, based on the Trust Account balance as of      , 2024, CSLM’s public shareholders may only receive approximately $    per Ordinary Share, and the warrants and rights will expire worthless. This will also cause shareholders to lose the investment opportunity in a target company and the chance of realizing future gains on their investment through any price appreciation in the combined company.

Risks Related to Being Deemed an Investment Company

If we were deemed to be an investment company for purposes of the Investment Company Act of 1940, as amended (the “Investment Company Act”), we may be forced to abandon our efforts to complete the Proposed Business Combination and instead be required to liquidate the Company.

There is currently uncertainty concerning the applicability of the Investment Company Act to a special purpose acquisition company (“SPAC”) and we may in the future be subject to a claim that we have been operating as an unregistered investment company. If we are deemed to be an investment company for purposes of the Investment Company Act, we might be forced to abandon our efforts to complete the Proposed Business Combination and instead be required to liquidate. If we are required to liquidate, our investors would not be able to realize the benefits of owning stock in a successor operating business, including the potential appreciation in the value of our stock and warrants following such a transaction, and our warrants would expire worthless.

The longer that the funds in the trust account are held in short-term U.S. government securities or in money market funds invested exclusively in such securities, the greater the risk that we may be considered an unregistered investment company, in which case we may be required to liquidate.

The proposed Trust Amendment would amend our existing Investment Management Trust Agreement (as amended, the “Trust Agreement”), dated as of January 12, 2022, and amended on July 13, 2023, by and between the Company and Continental Stock Transfer & Trust Company (the “Trustee”), allowing the Company to extend the Combination Period on a month-to-month basis until July 18, 2025 by depositing into the trust account (the “Trust Account”) $    for each one-month extension (each, an “Extension Payment”). A copy of the proposed Trust Amendment is attached to this proxy statement as Annex B. All shareholders are encouraged to read the proposed amendment in its entirety for a more complete description of its terms.

Reasons for the Trust Amendment

The purpose of the Trust Amendment Proposal is to allow the Company more time to complete the Proposed Business Combination. The Company’s IPO prospectus and the Existing Charter provide that the Company has until the Current Termination Date to complete a business combination. While the Company has signed a definitive business combination agreement, our board of directors currently believes that there will not be sufficient time before the Current Termination Date to complete the Proposed Business Combination and hold a general meeting at which to conduct a vote for shareholder approval of the Proposed Business Combination. Accordingly, our board of directors has determined it is in the best interests of the Company and our shareholders to extend the termination date from the Current Termination Date to the Extended Date.

If the Trust Amendment Is Not Approved

If based on the tabulated vote there are insufficient votes to approve the NTA Proposal, the Extension Proposal and the Trust Amendment Proposal, the Company may put the Adjournment Proposal to a vote as the first resolution in order to seek additional time to obtain sufficient votes in support of the NTA Proposal, the Extension Proposal and the Trust Amendment Proposal. If the NTA Proposal, the Extension Proposal and the Trust Amendment are not approved at the General Meeting, we expect to take all necessary actions and hold additional general meetings until October 18, 2024, to obtain the approval of the Extension Proposal and the Trust Amendment Proposal. If the NTA Proposal, the Extension Proposal and the Trust Amendment Proposal are not approved and we are unable to consummate the Proposed Business Combination prior to or on October 18, 2024, as provided in and in accordance with the Existing Charter, the Company shall (i) cease all operations except for the purpose of winding up and the redemption of 100% of the outstanding Public Shares in accordance with the procedures set forth in the Existing Charter; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-Share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust Account and not previously released to the Company to pay income taxes, if any, (less up to $100,000 of interest to pay dissolution expenses), divided by the number of Public Shares then in issue, which redemption will completely extinguish public Shareholders’ rights as Shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Shareholders and the Directors, liquidate and dissolve, subject in the case of sub-articles (ii) and (iii), to its obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. At such time, the Private Warrants will expire and the Sponsor will receive nothing upon a liquidation with respect to such Private Warrants, and the Private Warrants will be worthless.

The amount in the Trust Account (less approximately $1,897.50 representing the aggregate nominal par value of the shares issued in the IPO) under the Companies Act will be treated as a share premium which is distributable under the Companies Act, provided that immediately following the date on which the proposed

26

distribution is proposed to be made, we are able to pay our debts as they fall due in the ordinary course of business. If we are forced to liquidate the Trust Account, we anticipate that we would distribute to holders of the Public Shares issued in the IPO (the “Public Shareholders”) the amount in the Trust Account calculated as of the date that is two days prior to the distribution date (including any accrued interest). Prior to such distribution, we would be required to assess all claims that may be potentially brought against us by our creditors for amounts they are actually owed and make provision for such amounts, as creditors take priority over our Public Shareholders with respect to amounts that are owed to them. We cannot assure you that we will properly assess all claims that may be potentially brought against us. As such, our shareholders could potentially be liable for any claims of creditors to the extent of distributions received by them as an unlawful payment in the event we enter an insolvent liquidation. Furthermore, while we will seek to have all vendors and service providers (which would include any third parties we engaged to assist us in any way in connection with our search for a target business) and prospective target businesses execute agreements with us waiving any right, title, interest or claim of any kind they may have in or to any monies held in the Trust Account, there is no guarantee that they will execute such agreements. Nor is there any guarantee that, even if such entities execute such agreements with us, they will not seek recourse against the Trust Account or that a court would conclude that such agreements are legally enforceable.

Our Initial Shareholders, including our Sponsor, our officers and directors and the representative in our initial public offering, have agreed to waive their rights to participate in any liquidation of our Trust Account or other assets with respect to the insider shares and to vote their insider shares in favor of any dissolution and plan of distribution which we submit to a vote of shareholders. There will be no distribution from the Trust Account with respect to our private warrants, which will expire worthless.

If the Trust Amendment Is Approved

If the Charter Amendment and Trust Amendment are approved, the amendment to the Trust Agreement in the form of Annex B hereto will be executed and the Trust Account will not be disbursed except in connection with our completion of the Business Combination or in connection with our liquidation if we do not complete the Proposed Business Combination by the applicable termination date. The Company will then continue to attempt to consummate a business combination until the applicable termination date or until the Company’s Board of Directors determines in its sole discretion that it will not be able to consummate the Proposed Business Combination by the applicable termination date as described below and does not wish to seek an additional extension.

Required Vote

The Trust Amendment Proposal must be approved by a special resolution as a matter of Cayman Islands law, being a resolution passed by the affirmative vote of a majority of not less than two-thirds of the votes cast by the holders of the Ordinary Shares and Public Shares entitled to vote, in person or by proxy, at the General Meeting of the Company, of which notice specifying the intention to propose the resolution as a special resolution has been duly given. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, are not treated as votes cast and will have no effect on the Trust Amendment Proposal. As a result, if you abstain from voting on the Trust Amendment Proposal, your shares will be counted as present for purposes of establishing a quorum (if so present in accordance with the terms of our Existing Charter), but the abstention will have no effect on the outcome of such proposal.

Our Board has fixed the close of business on       , 2024, as the date for determining the Company’s shareholders entitled to receive notice of and vote at the General Meeting and any adjournment thereof. Only holders of record of the Company’s Ordinary Shares and Public Shares on that date are entitled to have their votes counted at the Special Meeting or any adjournment thereof.

BENEFICIAL OWNERSHIP OF SECURITIES

The following table sets forth information regarding the beneficial ownership of our ordinary shares as of the Record Date with respect to our ordinary shares held by:

Unless otherwise indicated, we believe that all persons named in the table have sole voting and investment power with respect to all ordinary shares beneficially owned by them. The following table does not reflect record or beneficial ownership of the private placement warrants as these are not exercisable within 60 days of the Record Date.

Our initial shareholders beneficially own approximately 49% of the issued and outstanding ordinary shares and have the right to elect all of our directors prior to our initial business combination as a result of holding all of the founder shares. Holders of our public shares will not have the right to appoint any directors to our board of directors prior to our initial business combination. In addition, because of their ownership block, our initial shareholders may be able to effectively influence the outcome of all other matters requiring approval by our shareholders, including amendments to our amended and restated memorandum and articles of association and approval of significant corporate transactions.

Subject to certain limited exceptions, our Initial Shareholders have agreed not to transfer, assign or sell their insider shares until six months after the date of the consummation of our initial business combination or earlier if, subsequent to our initial business combination, we consummate a subsequent liquidation, merger, stock exchange or other similar transaction which results in all of our shareholders having the right to exchange their Ordinary Shares for cash, securities or other property.

34

During the lock-up period, the holders of these shares will not be able to sell or transfer their securities except: (a) to our directors or officers, any affiliates or family members of any of our directors or officers, any members of our sponsor, or any affiliates of our sponsor, (b) in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of a trust, by distribution to one or more of the permissible beneficiaries of such trust; (e) in the case of an individual, pursuant to a qualified domestic relations order; (f) by private sales or transfers made in connection with the consummation of a business combination at prices no greater than the price at which the securities were originally purchased; (g) in the event of our liquidation prior to our completion of our initial business combination; (h) by virtue of the laws of its jurisdiction or its organizational documents or operating agreement; or (i) in the event of our completion of a liquidation, merger, share exchange, reorganization or other similar transaction which results in all of our shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property subsequent to our completion of our initial business combination; provided, however, that in the case of clauses (a) through (f) these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions.
