  1. The Ordinary Shares may be represented by American Depositary Shares, each of which currently represents one Ordinary Share. On June 24, 2026, Eli Lilly and Company ("Parent"), through its wholly owned subsidiary LDH XV Corporation ("Purchaser"), acquired all outstanding Ordinary Shares of Centessa Pharmaceuticals plc (the "Company") by means of a scheme of arrangement under Part 26 of the UK Companies Act 2006 (the "Scheme of Arrangement"), pursuant to the Transaction Agreement dated as of March 31, 2026, by and among the Company, Parent and Purchaser (the "Transaction Agreement"). At the effective time of the Scheme of Arrangement (the "Effective Time"), holders of Ordinary Shares became entitled to receive (a) $38.00 in cash per Ordinary Share (the "Cash Consideration"), without interest and less any applicable withholding taxes, and (b) one non-transferable contingent value right (a "CVR") entitling the holders to receive contingent payments of up to an aggregate of $9.00 per Ordinary Share, without interest and less any applicable withholding taxes, contingent upon the achievement of specified milestones set forth in the Contingent Value Rights Agreement between Parent, Purchaser and a rights agent mutually agreeable to the Company and Parent. Because each ADS represents one Ordinary Share, holders of ADSs became entitled to the same per-share consideration of $38.00 in cash plus one CVR per ADS. (continued from footnote 3) The transfer of Ordinary Shares occurred automatically at the Effective Time pursuant to the Scheme of Arrangement, without any action by or discretion of the Reporting Person. Includes 58,050 Ordinary Shares underlying Restricted Share Units ("RSUs"). Each RSU represented a contingent right to receive one Ordinary Share of the Company. Pursuant to the Transaction Agreement, at the Effective Time, each outstanding and unvested RSU became fully vested, and at the Effective Time, each RSU was automatically cancelled and converted into the right to receive (i) $38.00 in cash per Ordinary Share underlying such RSU award, without interest and less applicable withholding taxes, and (ii) one CVR per underlying Ordinary Share, in each case in accordance with the Transaction Agreement. No Ordinary Shares were issued upon settlement of RSUs prior to the Effective Time. Pursuant to the Transaction Agreement at the Effective Time, each outstanding share option, whether or not vested, was automatically cancelled and converted into the right to receive (i) an amount in cash equal to the excess of the Cash Consideration over the per-share exercise price of such option, without interest and less applicable withholding taxes, and (ii) one CVR per underlying Ordinary Share, in each case in accordance with the Transaction Agreement. No share options were exercised prior to the Effective Time.

Scheme of Arrangement regulatory
"acquired all outstanding Ordinary Shares of Centessa Pharmaceuticals plc ... by means of a scheme of arrangement under Part 26 of the UK Companies Act 2006"
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 (a "CVR") entitling the holders to receive contingent payments of up to an aggregate of $9.00 per Ordinary 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.
Restricted Share Units financial
"Includes 58,050 Ordinary Shares underlying Restricted Share Units ("RSUs"). Each RSU represented a contingent right to receive one Ordinary Share"
Restricted share units (RSUs) are a promise from a company to give an employee or service provider actual shares or cash equal to the shares after certain conditions are met, typically staying with the company for a set time or hitting performance targets. Think of them like a time-locked gift card that becomes usable only after you’ve earned it. For investors, RSUs matter because they align employee incentives with company performance and can increase the number of shares outstanding over time, diluting existing ownership and affecting earnings per share.
Cash Consideration financial
"holders of Ordinary Shares became entitled to receive (a) $38.00 in cash per Ordinary Share (the "Cash Consideration")"
Cash consideration is the actual money paid to buy a company, asset, or stake rather than payment in shares or other forms. For investors it matters because cash payments deliver immediate, certain value and affect the buyer’s and seller’s cash reserves and balance sheets—like selling a car for cash versus taking a trade-in, one side gets instant spending power while the other changes its liquidity and risk profile.
Transaction Agreement regulatory
"pursuant to the Transaction Agreement dated as of March 31, 2026, by and among the Company, Parent and Purchaser"

FAQ

What did Centessa (CNTA) officer Karen Anderson report in this Form 4?

Karen M. Anderson reported the automatic disposition of all her Centessa equity when Eli Lilly acquired the company. Her Ordinary Shares, RSUs, and share options were cancelled at the deal’s effective time in exchange for cash consideration and contingent value rights tied to future milestones.

What cash did Centessa (CNTA) shareholders receive per Ordinary Share in the Lilly deal?

Each Ordinary Share entitled the holder to receive $38.00 in cash, without interest and less applicable taxes. This fixed cash amount formed the core consideration paid by Eli Lilly under the scheme of arrangement and applied equally to holders of American Depositary Shares representing Ordinary Shares.

What is the contingent value right (CVR) mentioned for Centessa (CNTA) holders?

Each Ordinary Share also received one non-transferable contingent value right (CVR) for potential extra payments of up to $9.00 per share. These future payments depend on achieving specified milestones set out in a Contingent Value Rights Agreement with Eli Lilly and its acquisition subsidiary.

How were Centessa (CNTA) Restricted Share Units treated in the Lilly acquisition?

Unvested Restricted Share Units (RSUs) covering 58,050 Ordinary Shares held by Anderson became fully vested at the effective time. Each RSU was automatically cancelled and converted into the right to receive $38.00 in cash per underlying share plus one CVR, less applicable withholding taxes.

What happened to Centessa (CNTA) share options reported in this Form 4?

Each outstanding share option, whether vested or unvested, was automatically cancelled at the effective time. For each underlying Ordinary Share, the holder became entitled to cash equal to $38.00 minus the option’s exercise price, plus one CVR, instead of exercising the options.

Does Karen Anderson retain any Centessa (CNTA) shares or options after the Lilly deal?

No. After the automatic transfer and cancellation of her Ordinary Shares, RSUs, and share options at the transaction’s effective time, Anderson reported total holdings of zero Ordinary Shares and zero share options. Her economic interest shifted to cash consideration and associated contingent value rights.
