Centessa (CNTA) CBO Gregory Weinhoff Sells Shares to Cover Taxes

What Happened Gregory M. Weinhoff, Chief Business Officer of Centessa Pharmaceuticals plc (CNTA), had 14,158 shares disposed (withheld) on Feb 1, 2026 at $24.57 each to satisfy tax withholding obligations — proceeds ≈ $347,862. On Feb 2, 2026 he was granted/awarded a total of 154,000 share-equivalents: 31,000 shares (acquisition) and 123,000 RSU-type derivative awards (both reported at $0 intrinsic cost).

Key Details

  • Transaction dates: Feb 1, 2026 (tax withholding sale) and Feb 2, 2026 (awards/grants).
  • Sale/withholding: 14,158 shares × $24.57 = $347,862 (code F — tax/withholding disposition).
  • Grants: 31,000 shares reported as acquired and 123,000 derivative RSUs reported as acquired (both at $0).
  • Vesting: The RSUs are subject to vesting — they vest and settle in four equal annual installments, with the first annual vesting on Feb 2, 2027 (footnote). Another footnote notes certain option vesting occurs 1/48th monthly beginning Mar 2, 2026.
  • ADS note: Ordinary shares may be represented by American Depositary Shares (each ADS currently equals one Ordinary Share).
  • Shares owned after the transactions: not specified in the filing.
  • Filing timeliness: Report filed Feb 3, 2026 for Feb 1–2 transactions — appears timely (Form 4 is typically due within two business days).

Context

  • The 14,158-share disposal was a tax-withholding event (routine administrative sale) tied to equity awards, not an open-market sell for discretionary cash. The larger 154,000 share-related entries are awards/RSUs that generally vest over time and do not reflect an immediate acquisition of freely tradable shares.
