Rhea-AI Filing Summary

Centessa Pharmaceuticals agreed to be acquired by Eli Lilly via a UK court-sanctioned scheme of arrangement. Centessa shareholders will receive $38.00 in cash per share plus one contingent value right (CVR) worth up to an additional $9.00 per share tied to U.S. FDA approval milestones for cleminorexton (ORX750) or ORX142. The upfront cash implies an equity value of about $6.3 billion, with CVRs adding up to $1.5 billion of potential value and a stated 40.5% premium to Centessa’s 30‑day volume‑weighted average ADS price. The deal requires Centessa shareholder approval, High Court sanction, antitrust clearances and other customary conditions, and includes a ~$63 million termination fee payable by Centessa to Lilly in specified scenarios.

Positive

  • Lilly’s acquisition values Centessa at $38 cash per share, plus up to $9 per share in CVR milestones, implying approximately $6.3 billion upfront equity value and up to $1.5 billion additional potential value for CNTA holders.
  • The cash consideration reflects a 40.5% premium to Centessa’s 30‑day volume‑weighted average ADS price ended March 30, 2026, providing shareholders with a significant value uplift relative to recent trading levels.

Negative

  • None.

Insights

Lilly’s $6.3B Centessa buyout with up to $9/share CVR is a premium, milestone-dependent exit for CNTA holders.

Eli Lilly plans to acquire Centessa Pharmaceuticals for $38.00 per share in cash plus a CVR worth up to $9.00 per share tied to three regulatory milestones. The upfront cash values Centessa at about $6.3 billion, with CVRs adding up to $1.5 billion of potential equity value.

The cash offer represents a 40.5% premium to Centessa’s 30‑day VWAP, and key shareholders holding about 20%–24.1% of shares have signed voting and support agreements. Conditions include shareholder approvals, UK court sanction and antitrust clearance, with an outside date of September 30, 2026, extendable to March 31, 2027 for HSR timing.

Risks include possible competing bids, regulatory delays, failure to secure approvals, and that CVR milestones—such as U.S. FDA approvals for narcolepsy type 2, idiopathic hypersomnia and another indication by January 1, 2030—may never be met, in which case no CVR payments would be made. Centessa would owe a termination fee of about $63 million to Lilly in specified break scenarios.

Scheme of Arrangement regulatory
"will acquire the entire issued and to be issued share capital of the Company ... by means of a court-sanctioned scheme of arrangement"
A scheme of arrangement is a legal agreement between a company and its shareholders or creditors to reorganize or settle debts, often to avoid bankruptcy or make big changes. It’s like a carefully planned handshake that everyone agrees to, helping the company stay afloat or improve its financial health.
contingent value right financial
"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"
A contingent value right is a special security that gives its holder the right to receive one or more future payments only if specified events happen, such as a product reaching a sales target or getting regulatory approval. It matters to investors because it offers potential extra payout tied to uncertain outcomes—like a bet that a project will succeed—so it can add upside to a deal while also carrying extra risk and valuation uncertainty.
Hart-Scott-Rodino Antitrust Improvements Act of 1976 regulatory
"the expiration or termination of the applicable waiting period (and any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976"
Company Material Adverse Effect financial
"no Company Material Adverse Effect (as defined in the Transaction Agreement) having occurred that is continuing at the Effective Time"
A company material adverse effect is a significant, harmful change in a company’s business, financial condition, or operations that makes it much less valuable or viable. Investors care because this kind of change can trigger contract protections, delay or cancel deals, and often leads to a sharp re-evaluation of the stock — like discovering a serious health problem that suddenly changes future prospects and insurance coverage.
UK Takeover Code regulatory
"Centessa Pharmaceuticals plc is not a company subject to regulation under the United Kingdom City Code on Takeovers and Mergers (the “UK Takeover Code”)"
orexin receptor 2 (OX2R) agonists medical
"Centessa is advancing a pipeline of orexin receptor 2 (OX2R) agonists designed to address the neurobiological system critical to the sleep-wake cycle"
Molecules that activate the orexin receptor 2 (OX2R), a specific protein in the brain that helps regulate wakefulness and sleep; think of the drug as a key that fits a lock to switch on brain circuits that promote alertness. Investors track OX2R agonists because they can become treatments for sleep disorders and related conditions, so clinical trial results, safety data, and regulatory approvals can strongly affect a drug developer’s value and market potential.

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.

INDIANAPOLIS, BOSTON, and LONDON, March 31, 2026 – Eli Lilly and Company (NYSE: LLY) and Centessa Pharmaceuticals plc (Nasdaq: CNTA), a clinical-stage company developing a new class of medicines for the treatment of excessive daytime sleepiness and other neurological conditions, today announced a definitive agreement for Lilly to acquire Centessa.

Centessa is advancing a pipeline of orexin receptor 2 (OX2R) agonists designed to address the neurobiological system critical to the sleep-wake cycle to treat excessive daytime sleepiness and disorders of impaired wakefulness. Its lead investigational candidate cleminorexton (formerly ORX750) has demonstrated a potential best-in-class profile in Phase 2a clinical studies across narcolepsy type 1, narcolepsy type 2, and idiopathic hypersomnia. Centessa’s OX2R agonist portfolio includes additional clinical and preclinical-stage assets with potential utility across a broader range of neurological, neurodegenerative, and neuropsychiatric conditions.

“Orexin receptor biology represents one of the most compelling mechanistic opportunities in neuroscience as a direct intervention on the master switch of the sleep-wake cycle. Centessa has assembled a portfolio with the breadth and depth to improve wakefulness across a broad array of indications,” said Carole Ho, executive vice president and president, Lilly Neuroscience. “Joining forces with Centessa colleagues means we can now pursue that potential at the speed and scale it deserves.”

“Centessa is at the forefront of orexin science, and we’ve built a potential best-in-class portfolio of OX2R agonists with a level of depth and breadth that could help redefine what’s possible in neuroscience,” said Mario Alberto Accardi, PhD, Chief Executive Officer of Centessa and Founder of the Orexin Program. “Driven by a bold vision, our team has advanced an innovative portfolio with the speed, rigor and conviction needed to lead a new era of orexin-based therapeutics. Now, we are thrilled to take our next step toward a potential combination with Lilly who shares our vision. By combining Centessa’s team and capabilities with Lilly’s global complementary research, clinical, regulatory and commercial capabilities, we will seek to accelerate the advancement of our orexin portfolio across a broad range of neuroscience indications for the benefit of patients in need. I’m incredibly proud of what our team has achieved and deeply grateful to the investigators, study participants, employees and shareholders who have made our progress possible. This milestone reflects not only the strength of our science, but also the transformative potential of our orexin portfolio for patients who urgently need new solutions.”

Under the terms of the transaction agreement, Lilly will acquire all of the issued and to be issued share capital of Centessa (including the American Depositary Shares (ADSs) representing ordinary shares) for $38.00 in cash per share plus one non-transferrable contingent value right (CVR) that entitles the holder to receive up to an aggregate of $9.00 subject to the achievement of three milestones described below, for total potential aggregate per share consideration of up to $47.00. CVR holders would become entitled to receive contingent payments as follows: (i) $2.00 per CVR in cash, upon U.S. FDA approval of cleminorexton (formerly ORX750) or ORX142 for the treatment of narcolepsy type 2 prior to the fifth anniversary of transaction closing; (ii) $5.00 per CVR in cash, upon U.S. FDA approval of cleminorexton (formerly ORX750) or ORX142 for the treatment of idiopathic hypersomnia prior to the fifth anniversary of transaction closing; and (iii) $2.00 per CVR in cash, upon the first U.S. FDA approval of cleminorexton (formerly ORX750) or ORX142 for the treatment of any indication prior to January 1, 2030. There can be no assurance that any payments will be made with respect to the CVR.

The upfront cash consideration represents an aggregate equity value of approximately $6.3 billion and the CVR represents an additional potential aggregate equity value of approximately $1.5 billion.

The transaction, which will be effectuated by way of a scheme of arrangement under the laws of England and Wales, is expected to close in the third quarter, subject to approval by Centessa shareholders, sanction by the High Court of Justice of England and Wales and satisfaction of other customary closing conditions, including regulatory approvals.

The cash consideration payable at closing represents a premium of approximately 40.5% to the 30-day volume-weighted average trading price of Centessa’s ADSs ended on March 30, 2026. The boards of directors of both companies have approved the transaction.

To demonstrate their commitment to the transaction, entities affiliated with Medicxi Ventures, entities affiliated with Index Ventures, and affiliates of General Atlantic have signed voting and support agreements whereby they agree to vote to approve the transaction. The shares subject to the agreements represent a total of approximately 24.1% of Centessa’s outstanding ordinary shares (represented by ADSs).

Lilly will determine the accounting treatment of this transaction in accordance with Generally Accepted Accounting Principles (GAAP) upon closing. This transaction will thereafter be reflected in Lilly’s financial results and financial guidance.
