SLATTERY JOSEPH P 4

What Happened
Joseph P. Slattery, a director of Replimune Group, Inc. (REPL), was granted a derivative award on April 1, 2026 covering 44,500 shares. The filing reports the acquisition price as $0.00 (derivative award/option). The award vests in full on April 1, 2027. This was a compensation grant (not an open-market purchase or sale) and does not represent an immediate cash purchase or sale of stock.

Key Details

• Transaction date: 2026-04-01 (reporting period date); Form 4 filed 2026-04-07 (late filing).
• Transaction type/code: Award/Grant (A) — derivative (option-style award) for 44,500 shares, reported at $0.00.
• Vesting: Shares underlying the option vest entirely on April 1, 2027 (footnote).
• Shares owned after transaction: not disclosed in the Form 4 filing.
• Filing timeliness: Form 4 was filed late; filer cites an inadvertent administrative error (timeliness flag = L). Late filings delay public disclosure but do not change the substance of the grant.

Context
This is a typical director compensation award intended for retention; it is not the same as an insider purchasing shares on the open market. Because it's a derivative grant with a future vesting date, it does not necessarily indicate immediate buying or selling intent. Retail investors should view grants as routine compensation unless accompanied by other trading activity from the insider.
