Redinbo Greg 4

What Happened
Greg Redinbo, EVP Marketing & Applications at Axcelis Technologies (ACLS), had 723 shares withheld/forfeited to satisfy tax withholding obligations tied to the vesting of performance-based restricted stock units. The shares were valued at $86.58 each (closing price on March 2, 2026), for a total of $62,597. This was a tax-withholding disposition (code F), not an open-market sale.

Key Details

• Transaction date: March 2, 2026; filing date: March 3, 2026 (timely).
• Price used for withholding: $86.58 (closing price on March 2, 2026).
• Shares withheld/forfeited: 723; value: $62,597.
• Reason: Tax withholding on vesting of 2024 performance-based RSUs (PRSUs) granted in May 2024; the 2024 PRSUs were determined to be earned at 150% by the Compensation Committee.
• Vesting schedule note: Half of the earned PRSU shares vested Feb 28, 2025; the remaining half vested Feb 28, 2026 (this withholding relates to the Feb 28, 2026 vesting).
• Remaining holdings: Of the shares held after the vesting, 16,984 were issuable on vesting of other restricted stock units under the 2012 Equity Incentive Plan and remain subject to forfeiture.
• Transaction code: F = tax withholding (cashless/forfeiture to cover taxes), not an indication of a market sale.

Context
This is a routine tax-withholding event tied to RSU vesting (a common form of automatic share forfeiture to satisfy withholding). Such transactions reflect payroll tax mechanics rather than a deliberate insider sale for investment reasons.
