AXCELIS (ACLS) EVP Greg Redinbo Receives RSU Award, Shares Withheld
What Happened
- Greg Redinbo, EVP Marketing & Applications at Axcelis Technologies, was granted two awards of restricted stock units (3,115 RSUs each) on May 15, 2026 (total 6,230 RSUs).
- To satisfy tax withholding when some RSUs vested, 839 shares were forfeited/withheld (disposed) at the closing price of $155.18, totaling about $130,196 (452 shares = $70,141; 210 = $32,588; 177 = $27,467).
- These transactions are award grants (code A) and tax-withholding dispositions (code F) — routine equity compensation activity rather than an open-market sale.
Key Details
- Transaction date: May 15, 2026; Form 4 filed May 19, 2026 (timely within required reporting window).
- Grants: two awards of 3,115 RSUs each (total 6,230). Some awards are service-based RSUs; others are performance-based RSUs (performance payout can range 0–200% based on relative TSR for the 2026–2028 period).
- Tax withholding: 839 shares withheld at $155.18/share, total ~$130,196 (three withholding entries: 452, 210, 177 shares). These were shares retained by the company to satisfy tax obligations (not open-market sales).
- Shares remaining subject to forfeiture: the filing notes multiple RSU pools still subject to forfeiture (see company footnotes — e.g., 21,131 issuable on prior RSUs and others by grant).
- Transaction codes: A = award/grant, F = tax withholding. No indication of a 10b5-1 plan or late filing.
Context
- This was primarily a grant/vesting event: service RSUs typically vest one‑third on each of May 15, 2027–2029 (if employment continues). Performance RSUs are measured over 2026–2028 with vesting/settlement in 2029 if earned.
- The withholding of shares for taxes is a standard, routine part of RSU vesting (not necessarily a signal of insider selling intentions).
- For retail investors: award grants increase an insider’s stake potential but many shares remain subject to future vesting or performance conditions; tax-withheld shares reduce immediate share receipts but do not equal an open-market sale.
