The Merger Agreement provides that, among other things and upon the terms and subject to the conditions thereof, following the Domestication (as defined below) Merger Sub will merge with and into Fusemachines (the “Merger”), after which Fusemachines will be the surviving corporation (the “Surviving Corporation”) and a wholly-owned subsidiary of CSLM (the “Business Combination”). On August 27, 2024, CSLM entered into an amendment to the Merger Agreement (the “First Amendment”) whereby CSLM shall continue out of the Cayman Islands and into the State of Delaware so as to re-domicile as and become a Delaware corporation by means of a merger of CSLM with and into a newly formed Delaware corporation pursuant to the Cayman Islands Companies Law and the applicable provisions of the DGCL, with such newly formed Delaware corporation becoming the surviving corporation in the merger (the “Domestication”). In addition, the First Amendment included a provision that increased the amount the Company may borrow from the Sponsor from $2,000,000 to $2,750,000.

On February 4, 2025, CSLM entered into a second amendment to the Merger Agreement (the “2nd Amendment”) to (a) amend the definition of the “PIPE Investment Amount” to mean the sum of (i) $8,840,000, and (ii) the Contingent PIPE Investment Amount, if any; and (b) remove the delay fees incurred in connection with delivery of Fusemachines’ financial statements.

In connection with the 2nd Amendment, an affiliate (the “Sponsor Affiliate”) of Consilium Acquisition Sponsor I, LLC, a Cayman Islands limited liability company, CSLM’s sponsor (the “Sponsor”), provided financing to Fusemachines in the amount of $2,160,000, in exchange for a new convertible note which note shall convert into shares of common stock of Fusemachines at a price of $0.44 per share (a) automatically at the time of the Business Combination, or (b) on July 12, 2025 at the option of the holder, if not, then payable in cash (the “Escrow Note”). The funds from the Escrow Note shall be put in an escrow account held at Continental Stock Transfer and Trust Company, CSLM’s transfer agent (“CST”) pursuant to an escrow agreement among CSLM, the Sponsor Affiliate, Fusemachines and CST (the “Escrow Agreement”) and shall be released to the Surviving Corporation upon the consummation of the Business Combination.

However, while CSLM and Fusemachines may elect to update these forward-looking statements at some point in the future, CSLM and Fusemachines specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing CSLM’s and Fusemachines’s assessments as of any date subsequent to the date of this release. Accordingly, undue reliance should not be placed upon the forward-looking statements.
