Bunn Paul A. 4

What Happened
Paul A. Bunn, a director of Verastem, Inc. (VSTM), received a grant of 36,000 restricted stock units (RSUs) on May 21, 2026. The Form 4 reports the acquisition price as $0.00 (transaction code A for Award/Grant); the filing shows the reported dollar amount as $0 for the acquisition entry. These RSUs give Bunn the contingent right to receive one share of common stock per RSU upon vesting.

Key Details

• Transaction date: May 21, 2026 (reported on Form 4 filed May 26, 2026).
• Transaction type/code: Award/Grant (A). Reported acquisition price: $0.00; reported total value for the line: $0.
• Number of RSUs granted: 36,000.
• Shares owned after transaction: Not disclosed on the Form 4.
• Vesting terms (footnote F1): RSUs vest in 12 substantially equal monthly installments — first eleven vest on the last day of each month from June 2026 through April 2027; the final installment vests on the earlier of the day before the 2027 annual meeting or May 31, 2027 — vesting contingent on continued service as a director.
• Timeliness: The Form 4 was filed five days after the grant date; this is later than the usual 2-business-day Form 4 filing deadline and appears to be a late filing.

Context
RSU grants are a common form of equity compensation for directors and typically vest over time; they do not indicate an immediate purchase or sale. Because these RSUs vest monthly over the coming year, they will convert to shares only as each installment vests (subject to continued service). The $0.00 acquisition amount on the Form 4 reflects the award reporting convention and does not denote market value received.
