Redinbo Greg 4

What Happened
Greg Redinbo, EVP Marketing and Applications at Axcelis (ACLS), had restricted stock units vest on May 16, 2026 and surrendered shares to cover the tax withholding obligation. The filing shows two forfeitures on May 18, 2026: 111 shares at $146.24 ($16,233) and 79 shares at $146.24 ($11,553), totaling about $27,786. This was a tax-withholding (forfeiture) transaction, not an open-market sale.

Key Details

• Transaction date(s): May 18, 2026 (relates to RSU vesting on May 16, 2026)
• Price used: $146.24 per share (closing price on withholding date)
• Shares forfeited to cover taxes: 111 and 79 (total 190 shares) — proceeds/value approx. $27,786
• Footnotes: Withholding relates to RSUs granted May 2022; shares issued on vesting were reduced to satisfy tax withholding. The filing also notes remaining RSU amounts (20,756 and 20,488 shares) that are issuable on vesting and subject to forfeiture.
• Filing timeliness: Form filed May 20, 2026 (appears timely under Form 4 rules).

Context
This was a routine tax-withholding (F code) tied to RSU vesting — essentially a cashless/forfeiture method where the company retains shares to cover taxes. Such withholdings are administrative and do not necessarily indicate the insider is buying or selling for investment reasons.
