    Item 1.01

    Entry into a Material Definitive Agreement.

    Transaction Agreement

    On March 31, 2026, Centessa Pharmaceuticals plc, a public limited company registered in England and Wales (the “Company”), entered into a Transaction Agreement (the “Transaction Agreement”) with Eli Lilly and Company, an Indiana corporation (“Parent”), and LDH XV Corporation, a Delaware corporation and direct wholly owned subsidiary of Parent (“Purchaser”). Under the terms of the Transaction Agreement, Purchaser (and/or at Parent’s election, its nominee(s)) will acquire the entire issued and to be issued share capital of the Company (the “Acquisition”) by means of a court-sanctioned scheme of arrangement under Part 26 of the United Kingdom Companies Act of 2006 (the “Scheme of Arrangement”). Upon the Scheme of Arrangement becoming effective, the Company will become a wholly owned subsidiary of Purchaser.

    At the effective time of the Scheme of Arrangement (the “Effective Time”), holders of the ordinary shares of the Company, with a nominal value £0.002 per share (the “Company Shares” (including Company Shares represented by the American Depositary Shares of the Company (the “ADSs”))), will be entitled to receive (i) $38.00 in cash per Company Share, without interest (the “Cash Consideration”), plus (ii) one non-transferable contingent value right entitling the holders to receive contingent cash payments of up to an aggregate of $9.00 per Company Share, without interest, contingent upon the achievement of specified milestones set forth in the CVR Agreement (as defined below) (such contingent value rights, the “CVRs” and, together with the Cash Consideration, the “Transaction Consideration”). The Acquisition and the Scheme of Arrangement have been recommended by the board of directors of the Company (the “Company Board”) and the boards of directors of Parent and Purchaser.

    Treatment of Company Equity Awards

    The Transaction Agreement provides for the following treatment of the Company’s outstanding equity awards at the Effective Time:

     

      •  

    each option to purchase Company Shares granted under any Company equity incentive plan, program or arrangement under which equity awards are outstanding (the “Company Share Plans”) (each, a “Company Option”) having an exercise price less than the Cash Consideration (each such option, a “Company Cash-Out Option”) that is outstanding immediately prior to the Effective Time, whether or not vested, will be canceled, and, in exchange therefor, the holder of such canceled Company Cash-Out Option will be entitled to receive (without interest), in consideration of the cancellation of such Company Cash-Out Option (A) an amount in cash (less applicable tax withholdings pursuant to the Transaction Agreement) equal to the product of (1) the total number of Company Shares subject to such Company Cash-Out Option immediately prior to the Effective Time multiplied by (2) the excess, if any, of the Cash Consideration over the applicable exercise price per Company Share under such Company Cash-Out Option and (B) one (1) CVR for each Company Share subject to such Company Cash-Out Option immediately prior to the Effective Time (without regard to vesting);

     

      •  

    each Company Option having an exercise price that is equal to or greater than the Cash Consideration (each such option, a “Company Underwater Option”) that is outstanding immediately prior to the Effective Time, to the extent not vested, will become fully vested as of prior to the Effective Time, and the Company shall permit the holders of Company Underwater Options to exercise such Company Underwater Options prior to the Effective Time on a basis that allows the Company Shares acquired pursuant to such exercise to be treated as Scheme Shares (as defined in the Transaction Agreement) at the Effective Time, with any Company Underwater Options that remain outstanding and unexercised as of the Effective Time cancelled for no consideration at the Effective Time, without any action on the part of Purchaser, the Company or any other Person;

     

      •  

    each restricted stock unit granted under the Company Share Plans or otherwise (each such restricted stock unit, a “Company RSU”) that is outstanding and unvested shall become immediately vested in full, and at the Effective Time, each Company RSU will be canceled, and, in exchange therefor, the holder of such canceled Company RSU will be entitled to receive (without interest), in consideration of the cancellation of such Company RSU, (A) an amount in cash (less applicable Tax withholdings pursuant to the Transaction

     


     

    Agreement) equal to the product of (1) the total number of shares subject to such Company RSU immediately prior to the Effective Time, multiplied by (2) the Cash Consideration and (B) one (1) CVR for each Company Share subject to such Company RSU immediately prior to the Effective Time (without regard to vesting).

    Conditions to Completion of the Acquisition

    The Acquisition is subject to customary closing conditions, including, among other things: (a) the approval of the Scheme of Arrangement by a majority in number representing not less than three-fourths (75%) in value of the members or class of members (as the case may be) present and voting (either in person or by proxy) at the Scheme Meeting (as defined in the Transaction Agreement) (including any separate class meeting which may be required by the High Court of Justice of England and Wales (the “Court”)) and the passing of the Company Shareholder Resolution (as defined in the Transaction Agreement) by members representing not less than three-fourths (75%) of the total voting rights of eligible members present and voting (either in person or by proxy) at the Company GM (as defined in the Transaction Agreement), (b) the sanctioning of the Scheme of Arrangement by the Court, (c) the expiration or termination of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), (d) the absence of any order, decree or ruling that remains in effect and enjoins, prevents, prohibits, or makes illegal the consummation of the Contemplated Transactions, (e) that each party’s respective representations and warranties, subject to certain customary materiality standards set forth in the Transaction Agreement, shall be true and correct as of the Effective Time, (f) the performance or compliance in all material respects with the other party’s obligations under the Transaction Agreement, and (g) no Company Material Adverse Effect (as defined in the Transaction Agreement) having occurred that is continuing at the Effective Time.

    Representations and Warranties; Covenants

    The Transaction Agreement includes customary representations, warranties and covenants of the Company, Parent and Purchaser. The Company has agreed, among other things, to use commercially reasonable efforts to operate its business in the ordinary course until the earlier of the Effective Time or the date the Transaction Agreement is terminated, and not to engage in specified types of transactions during such period. The Company has also agreed to customary non-solicitation restrictions, including not to initiate, solicit, knowingly encourage or knowingly facilitate discussions with third parties regarding other proposals for alternative business combination transactions involving the Company or change the recommendation of the Company Board to the Company’s shareholders regarding the Scheme of Arrangement, in each case, except as otherwise permitted by the Transaction Agreement, including to enter into an alternative transaction that constitutes a Superior Proposal (as defined in the Transaction Agreement) in compliance with the Company Board’s fiduciary duties under applicable law and subject to payment of a termination fee. Parent, Purchaser and the Company have agreed to use reasonable best efforts to take actions that may be required in order to obtain antitrust approval of the proposed transaction, subject to certain limitations.

    Termination and Termination Fee

    The Transaction Agreement also includes customary termination provisions for both the Company and Parent, including, among others, the right of both parties to terminate for failure to consummate the transactions contemplated by the Transaction Agreement and the Scheme of Arrangement (together, the “Contemplated Transactions”) on or before September 30, 2026, which date shall be extended to March 31, 2027 if the closing condition regarding the expiration of the waiting period (and any extension thereof) under the HSR Act remains unsatisfied. If the Transaction Agreement is terminated under certain circumstances specified in the Transaction Agreement, the Company will be required to pay Parent a termination fee of approximately $63 million (including under specified circumstances in connection with the Company’s entry into an agreement with respect to a Superior Proposal or the Company Board’s change of recommendation in favor of the Acquisition). The parties to the Transaction Agreement are also entitled to specifically enforce the terms and provisions of the Transaction Agreement.

    The Company Board has resolved (i) that the Transaction Agreement, the Scheme of Arrangement, the CVR Agreement (as defined below) and the Voting and Support Agreements (as defined below) and the other transactions contemplated thereby are in the best interests of the Company and would promote the success of the Company for the benefit of the Company’s shareholders as a whole; (ii) that the execution, delivery and performance by the Company of its covenants and obligations contained in the Transaction Agreement and the Scheme of Arrangement and the

     


    consummation of the Contemplated Transactions, be and are approved; and (iii) to recommend to the Company’s shareholders the approval of the Scheme of Arrangement at the scheme meeting and the passing of the Company Shareholder Resolution at the Company GM.

    The foregoing description of the Transaction Agreement has been included to provide investors and stockholders with information regarding the terms of such agreements. The assertions embodied in the representations and warranties contained in the Transaction Agreement are qualified by information in confidential disclosure schedules delivered by the Company to Purchaser in connection with the signing of the Transaction Agreement. Moreover, certain representations and warranties in the Transaction Agreement were made as of a specified date, may be subject to a contractual standard of materiality different from what might be viewed as material to shareholders, or may have been used for the purpose of allocating risk between the parties to the Transaction Agreement. Accordingly, the representations and warranties in the Transaction Agreement should not be relied on by any persons as characterizations of the actual state of facts and circumstances of the Company at the time they were made and investors should consider the information in the Transaction Agreement in conjunction with the entirety of the factual disclosure about the Company in the Company’s public reports filed with the U.S. Securities and Exchange Commission (the “SEC”). Information concerning the subject matter of the representations and warranties may change after the date of the Transaction Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

    Voting and Support Agreements

    On March 31, 2026, in connection with the execution and delivery of the Transaction Agreement, entities affiliated with Medicxi Ventures, entities affiliated with Index Ventures and affiliates of General Atlantic (collectively, the “Supporting Shareholders”), solely in their respective capacities as shareholders of the Company, each entered into a voting and support agreement (collectively, the “Voting Agreements”) with Parent and the Company, pursuant to which each Supporting Shareholder agreed, among other things, (i) to vote (or cause to vote) in favor of the Scheme of Arrangement and the Company Shareholder Resolution, (ii) to vote against other proposals to acquire the Company and (iii) to certain other restrictions on its ability to take actions with respect to the Company and its Company Shares. The Supporting Shareholders collectively beneficially own approximately 20% of the outstanding Company Shares as of March 27, 2026.

    The Voting Agreements have been included to provide information regarding their terms. They are not intended to modify or supplement any factual disclosures about the applicable Supporting Shareholder or the Company in any public reports filed with the SEC by the Company.

    The foregoing description of the Voting Agreements is qualified in all respects by reference to the full copy of the form of Voting Agreement, which is attached as Exhibit 10.1 hereto and incorporated by reference herein.

    Contingent Value Rights Agreement

    At or prior to the Effective Time, Purchaser, Parent, and the Rights Agent (as defined therein) will enter into a Contingent Value Rights Agreement (the “CVR Agreement”), substantially in the form attached as Annex I to the Transaction Agreement. Pursuant to the Transaction Agreement, each holder of Company Shares (including Company Shares represented by the ADSs) and each holder of a Company Covered Award (as defined in the CVR Agreement) will be entitled to receive one CVR for each Company Share or Company Covered Award, as applicable, which represents the right to receive contingent cash payments, without interest and less any applicable tax withholding upon the achievement of the applicable milestone as described below:

     

      •  

    $2.00 per CVR in cash upon the occurrence of receipt of the first regulatory approval of a New Drug Application (“NDA”) in the United States for ORX750 or ORX142, as each such exists as the date of the Transaction Agreement, together with any modifications or improvements to such applicable product candidate (each, a “CVR Product”) for the treatment of any indication, by 11:59 p.m. ET on December 31, 2029 (the “Indication Milestone”);

     


      •  

    $5.00 per CVR in cash upon the occurrence of receipt of the first regulatory approval of an NDA in the United States for a CVR Product for the treatment of idiopathic hypersomnia, prior to the fifth anniversary of the closing of the Acquisition (the “IH Milestone”); and

     

      •  

    $2.00 per CVR in cash upon the occurrence of receipt of the first regulatory approval of an NDA in the United States for a CVR Product for the treatment of narcolepsy type 2, prior to the fifth anniversary of the closing of the Acquisition (the “NT2 Milestone”).

     

      •  

    If both the IH Milestone and NT2 Milestone are achieved prior to the expiration of the Indication Milestone, all three milestones will become due and payable in accordance with the CVR Agreement.

    The CVR will be subject to the terms and conditions set forth in the CVR Agreement. Each CVR represents a contractual right only. The CVRs will not be transferable, except in the limited circumstances specified in the CVR Agreement, will not be evidenced by certificate or other instrument and will not be registered or listed for trading. The CVRs will not have any voting or dividend rights and will not represent any equity or ownership interest in Purchaser or the Company.

    Any potential payout of the CVR is subject to various risks and uncertainties related to the development of ORX750 or ORX142 and U.S. Food and Drug Administration clearances as more fully described in the Company’s periodic reports filed with the SEC.

    There can be no assurance that the milestones set forth in the CVR Agreement will be achieved prior to their expiration or termination of the CVR Agreement, or that payment will be required of Parent with respect to the milestones under the CVR Agreement.

    The foregoing description of the CVR Agreement does not purport to be complete and is subject to, and is qualified in its entirety by, the full text of the form of the CVR Agreement, a copy of which is attached as Annex I to the Transaction Agreement filed as Exhibit 2.1 herewith and is incorporated into this Item 1.01 by reference.

Any

     


    forward-looking statements are based on current beliefs and expectations and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in, or implied by, such forward-looking statements.
