Evans Eileen 4

What Happened Eileen Evans, EVP, General Counsel and Secretary of Axcelis Technologies (ACLS), received equity awards on May 15, 2026 consisting of two grants of 3,893 restricted stock units (RSUs) each (total 7,786 RSUs). Simultaneously, 867 shares were forfeited/withheld to satisfy tax withholding obligations related to a prior RSU vesting, with a withholding value calculated at $155.18 per share (867 x $155.18 = $134,541).

Key Details

• Transaction types: A = Award/Grant (two awards of 3,893 RSUs) and F = Tax withholding (867 shares disposed to cover taxes).
• Transaction date: May 15, 2026; Form 4 filed May 19, 2026 (timely within required business-day window).
• Tax withholding: 867 shares withheld at $155.18 closing price (total value $134,541).
• Vesting/forfeiture notes: Newly granted RSUs include service-vesting and performance-based awards; several footnotes disclose RSUs subject to future forfeiture/vesting (examples cited in filing: 27,723; 31,616; and 29,823 shares are referenced as issuable on vesting and subject to forfeiture).
• Award vesting schedules: Service RSUs generally vest one-third on each of May 15, 2027, 2028 and 2029 (assuming continued employment). Performance RSUs may pay 0–200% based on relative total shareholder return for 2026–2028, with earned shares measured/vesting in 2029.

Context

• These transactions are primarily award/grant activity (not an open-market purchase or sale). Awards and tax-withholdings are common executive compensation mechanics — awards indicate compensation alignment but are not the same as an outright purchase (which some investors view as a stronger bullish signal).
• The 867-share disposal was a tax withholding related to vested RSUs (cashless-like withholding), not an open-market sale.
