    Item 1.01. Entry into a Material Definitive Agreement.

     

    Merger Agreement

     

    On February 6, 2025, Alumis Inc., a Delaware corporation (“Alumis”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ACELYRIN, Inc., a Delaware corporation (“ACELYRIN”), and Arrow Merger Sub, Inc., a Delaware corporation and a direct wholly owned subsidiary of Alumis (“Merger Sub”). Pursuant to the Merger Agreement, Merger Sub will be merged with and into ACELYRIN and ACELYRIN will continue as the surviving corporation and direct wholly owned subsidiary of Alumis (the “Merger”).

     

    Approval & Recommendation

     

    Based on the unanimous recommendation of a special committee (the “Alumis Special Committee”) of the board of directors of Alumis (the “Alumis Board”), consisting solely of independent and disinterested directors of Alumis, to which the Alumis Board had delegated exclusive authority to consider, negotiate and evaluate the Merger Agreement and the transactions contemplated thereby, the Alumis Board (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are advisable, fair to and in the best interests of Alumis and its stockholders, (ii) approved the Merger and the transactions contemplated thereby, including the issuance of voting common stock of Alumis, par value $0.0001 per share (“Alumis Common Stock”) pursuant to the Merger Agreement (the “Alumis Share Issuance”), and (iii) resolved to submit and recommend the approval of the Alumis Share Issuance to Alumis’s stockholders.

     

    Based on the unanimous recommendation of a special committee (the “ACELYRIN Special Committee”) of the board of directors of ACELYRIN (the “ACELYRIN Board”), consisting solely of independent and disinterested directors of ACELYRIN, to which the ACELYRIN Board had delegated exclusive authority to consider, negotiate and evaluate the Merger Agreement and the transactions contemplated thereby, the ACELYRIN Board (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Merger, are advisable, fair to and in the best interests of ACELYRIN and its stockholders, (ii) approved the execution, delivery and performance by ACELYRIN of the Merger Agreement and the consummation by ACELYRIN of the transactions contemplated thereby, including the Merger and (iii) declared advisable and resolved to recommend that ACELYRIN’s stockholders approve and adopt the Merger Agreement.

     

    Merger Consideration; Treatment of Equity Awards

     

    In connection with the Merger, all of the issued and outstanding shares of common stock of ACELYRIN, par value $0.00001 per share (the “Shares”), will be cancelled and converted into the right to receive 0.4274 shares of Alumis Common Stock, without interest (the number of shares of Alumis Common Stock in exchange for each Share, the “Exchange Ratio”) and, if applicable, cash in lieu of fractional shares, without interest, subject to any applicable withholding.

     

    Each of ACELYRIN’s stock options (the “Options”) that is outstanding and unexercised as of immediately prior to the effectiveness of the Merger (the “Effective Time”) and that has a per share exercise price of $18.00 or less will be converted into an option award to purchase the number of shares of Alumis Common Stock (each, a “Converted Option”) equal to (i) the number of Shares subject to the Option immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio. Each Converted Option will have an exercise price per share of Alumis Common Stock equal to (x) the per share exercise price for Shares subject to the corresponding Option immediately prior to the Effective Time divided by (y) the Exchange Ratio. Each Option that is outstanding and unexercised immediately prior to the Effective Time and that has a per share exercise price of more than $18.00 will be cancelled without the payment of any consideration.

     

    Each of ACELYRIN’s restricted stock unit awards (the “RSUs”) that is outstanding and unvested as of immediately prior to the Effective Time will be converted into an RSU with respect to a number of shares of Alumis Common Stock equal to (i) the total number of Shares subject to the RSU immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio.

     

     

     

     

    Each of ACELYRIN’s performance stock unit awards (the “PSUs”) that is outstanding and unvested as of immediately prior to the Effective Time will have any performance-based conditions deemed to be met at 100% of the target level of performance and be assumed and converted into an RSU with respect to a number of shares of Alumis Common Stock equal to (i) the target number of Shares subject to the PSU immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio.

     

    Closing Conditions

     

    Consummation of the Merger is subject to certain closing conditions, including the absence of any law or judgment that restrains, enjoins or otherwise prohibits consummation of the Merger, the effectiveness of a registration statement on Form S-4 (the “registration statement”) to be filed with the Securities and Exchange Commission (the “SEC”) by Alumis, adoption of the Merger Agreement by the holders of a majority of the outstanding Shares at ACELYRIN’s stockholders’ meeting, and approval of the Alumis Share Issuance by the holders of a majority of votes of Alumis’s Common Stock cast at Alumis’s stockholders’ meeting.

     

    Representations, Warranties and Covenants

     

    The Merger Agreement includes representations, warranties and covenants of the parties customary for a transaction of this nature, including covenants regarding the conduct of their respective businesses. ACELYRIN and Alumis are not permitted to, among other things, solicit, initiate, knowingly induce, knowingly encourage, or knowingly facilitate any inquiries or the making of any proposal or offer that constitutes, or would reasonably be expected to lead to, an alternative transaction proposal or to engage in discussions or negotiations with third parties regarding any alternative transaction proposal. Notwithstanding this limitation, prior to a party’s stockholders’ approving the transaction, such party may under certain circumstances provide information to and engage or participate in discussions or negotiations with third parties with respect to an unsolicited, bona fide written alternative transaction proposal that its board of directors has determined in good faith constitutes or could reasonably be expected to result in a superior proposal and failure to take such action would reasonably be expected to be inconsistent with the directors’ fiduciary duties under applicable law. Each party’s board of directors may change its recommendation to its stockholders (subject to the other party’s right to match and right to terminate the Merger Agreement following such change in recommendation) in response to a superior proposal or an intervening event if the board of directors determines in good faith that the failure to take such action would be inconstant with the directors’ fiduciary duties under applicable law. Each party may also terminate the Merger Agreement in order to enter into a transaction constituting a superior proposal.

     

    Governance

     

    The Merger Agreement provides that the parties will take all actions reasonably necessary such that, from and after the Effective Time, the Alumis Board is increased to nine individuals and that two directors designated by ACELYRIN are elected or appointed to the Alumis Board.

     

    Termination and Termination Fees

     

    The Merger Agreement contains certain termination rights for both Alumis and ACELYRIN, including the right of either party to terminate the Merger Agreement if the transactions have not been consummated prior to July 7, 2025. The Merger Agreement further provides that, in connection with the termination of the Merger Agreement by ACELYRIN under certain circumstances, including termination by ACELYRIN to accept and enter into a definitive agreement with respect to a superior proposal, ACELYRIN must pay Alumis a termination fee of $10 million. In connection with the termination of the Merger Agreement by Alumis under certain circumstances, including termination by Alumis to accept and enter into a definitive agreement with respect to a superior proposal, Alumis must pay ACELYRIN a termination fee of $10 million.

     

    Additional Information

     

    The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 hereto and which is incorporated herein by reference.

     

     

     

     

    The Merger Agreement has been filed to provide information to investors regarding its terms. The Merger Agreement is not intended to provide any other factual information about Alumis or ACELYRIN, their respective businesses, the actual conduct of their respective businesses during the period prior to the consummation of the Merger or the other transactions contemplated therein. The Merger Agreement contains representations and warranties that are the product of negotiations among the parties thereto which were made only for purposes of such agreement and as of specified dates. The assertions embodied in those representations and warranties are subject to qualifications and limitations agreed to by the respective parties and are also qualified in important part by confidential disclosure letters delivered by and to each of Alumis and ACELYRIN in connection with the Merger Agreement. The representations and warranties may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to stockholders or investors. Information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in Alumis’ or ACELYRIN’s public disclosures.
