The option carries a 10-year term with an expiration date of 20 June 2035.

No open-market purchases or sales of CNTA ordinary shares or ADSs were reported, and the filing does not indicate transactions made under a Rule 10b5-1 plan.
Centessa Pharmaceuticals plc (NASDAQ: CNTA) has submitted a Form 144 notifying the SEC of a proposed sale of 12,000 common shares by an insider through UBS Financial Services on 24 June 2025. The estimated aggregate market value is $168,218.40, implying a per-share price of roughly $14.02. The filing states that 133,618,774 shares are outstanding, meaning the planned sale represents less than 0.01 % of total shares.

The insider previously sold a combined 6,000 shares over the past three months for total proceeds of $84,012.01. No additional operational or financial data were disclosed, and the signatory affirms awareness of no undisclosed material adverse information. Given the modest size relative to the float and the routine nature of Form 144 notices, the event is unlikely to materially affect Centessa’s fundamentals or valuation.

Centessa Pharmaceuticals plc (CNTA) – Form 144 filing overview
An affiliate identified as Saurabh Saha has notified the SEC of an intent to sell 55,000 common shares through UBS Financial Services on or about 20 June 2025. The filing quotes an aggregate market value of $707,575.
The issuer reports 133,618,774 shares outstanding; the proposed sale therefore represents roughly 0.04 % of the float, well below Rule 144’s 1 % ceiling. The shares were obtained the same day (20 Jun 2025) via a cash exercise of stock options.
Recent trading history: the same seller executed four transactions in the past three months, disposing of a total of 165,000 shares for gross proceeds of $2.30 million on 20 Mar, 21 Apr, 22 Apr and 20 May 2025. No 10b5-1 plan date or explanatory remarks were supplied.
Investor take-away: While the volume is immaterial to Centessa’s capital structure, consecutive insider sales may attract scrutiny as a potential sentiment indicator. The filing expressly states that the seller is not aware of undisclosed material information, but it offers no context regarding the rationale for continued sales.
