Rhea-AI Filing Summary

Medicxi Ventures Management (Jersey) Ltd reported open-market sale transactions in this Form 4 filing.

Centessa Pharmaceuticals plc disclosed that investment entities affiliated with Medicxi completed the transfer of a total of 19,963,157 Ordinary Shares in connection with the acquisition of Centessa by Eli Lilly and Company. The transfer occurred automatically at the effective time of a UK Scheme of Arrangement, not through discretionary open-market trading by the reporting entities.

Under the deal, each Ordinary Share (and each ADS representing one Ordinary Share) entitled holders to receive $38.00 in cash per share, plus one non-transferable contingent value right for potential additional payments of up to $9.00 per share upon achievement of specified milestones. Following these transactions, the reported Medicxi-related holdings of Centessa Ordinary Shares decreased to zero, and the reporting persons note they disclaim beneficial ownership except to the extent of any pecuniary interest.

Positive

  • Full cash exit with milestone-based upside: Each Centessa share is exchanged for $38.00 in cash plus a contingent value right for up to an additional $9.00 per share tied to specified milestones, combining immediate liquidity with potential future value.

Negative

  • None.

Insights

Eli Lilly’s cash-and-CVR takeover crystallizes value for Centessa holders.

The transactions show all Centessa Ordinary Shares held by Medicxi-affiliated funds were transferred as part of Eli Lilly’s acquisition, executed via a Scheme of Arrangement. This is a full-company sale, not routine secondary selling.

Each share receives $38.00 in cash plus a contingent value right for up to an additional $9.00 per share if specified milestones are reached. The CVR structure ties upside to clearly defined future events, while the upfront cash provides immediate liquidity to former shareholders.

The filing also notes the transfers occurred automatically at the Effective Time, and the Medicxi entities disclaim beneficial ownership beyond any pecuniary interest. Future disclosures from Eli Lilly or rights-agent reports would determine whether CVR milestones are met and additional payments become payable.

Scheme of Arrangement regulatory
"acquired all outstanding Ordinary Shares ... 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"
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.
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.
American Depositary Shares financial
"The Ordinary Shares may be represented by American Depositary Shares ("ADSs"), each of which currently represents one Ordinary Share"
American depositary shares (ADSs) are a way for investors in the United States to buy shares of foreign companies without dealing with international markets directly. They represent ownership in a foreign company's stock and are traded on U.S. stock exchanges, making it easier for American investors to buy, sell, and own parts of companies from around the world.
pecuniary interest financial
"The Reporting Persons disclaim Section 16 beneficial ownership ... except to the extent of their respective pecuniary interest therein"

FAQ

What did Centessa Pharmaceuticals (CNTA) shareholders receive in the Eli Lilly acquisition?

Centessa shareholders receive $38.00 in cash per Ordinary Share plus one contingent value right. The CVR can pay up to an additional $9.00 per share if specified milestones in the Contingent Value Rights Agreement are achieved.

How many Centessa (CNTA) shares were transferred by Medicxi-affiliated entities?

Medicxi-affiliated entities reported the transfer of 19,963,157 Centessa Ordinary Shares. These transfers occurred automatically at the effective time of the Scheme of Arrangement implementing Eli Lilly’s acquisition, rather than through discretionary open-market trading decisions.

Do Centessa (CNTA) American Depositary Shares get the same merger consideration?

Yes. Each American Depositary Share represents one Ordinary Share, so ADS holders are entitled to the same $38.00 in cash plus one contingent value right per ADS, mirroring the consideration per Ordinary Share in the Eli Lilly acquisition.

Was the Medicxi sale of Centessa (CNTA) shares an open-market transaction?

No. Although coded as sales, the filing explains the Ordinary Shares transferred automatically at the Effective Time of the Scheme of Arrangement. The Medicxi reporting persons exercised no discretion over timing, and the transfers followed the agreed acquisition terms.

Do Medicxi entities still hold Centessa Pharmaceuticals (CNTA) shares after the deal?

After the Eli Lilly acquisition became effective, the Form 4 shows Medicxi-affiliated entities with zero Ordinary Shares reported. They also disclaim beneficial ownership of the prior holdings except to the extent of any pecuniary interest in the partnerships.
