Mahoney Robert John 4

What Happened

• Robert John Mahoney, EVP Global Operations at Axcelis Technologies, received two awards of 1,947 restricted stock units (RSUs) each on May 15, 2026 (total 3,894 RSUs; grant price reported as $0.00 — i.e., equity awards).
• To satisfy tax withholding on vested RSUs, 776 shares were surrendered/withheld (reported as disposals) at $155.18 per share, producing proceeds/value of about $120,420 (aggregate of four withholding entries: 372, 173, 170 and 61 shares).
• These actions are award/grant entries (code A) and tax-withholding/forfeiture entries (code F) — administrative transactions rather than open-market purchases or discretionary sales.

Key Details

• Transaction date(s): May 15, 2026; Form 4 filed May 19, 2026 (filed within the normal 2-business-day window).
• Withholding sale price used: $155.18 (closing price cited in filing).
• Shares surrendered for tax withholding: 776 shares; total withholding value ≈ $120,420.
• Grants: two RSU grants of 1,947 shares each. Footnotes indicate some grants are service-vesting (typically 1/3 vesting each year 2027–2029) and at least one grant includes performance-based units (0–200% payout tied to relative TSR for 2026–2028, vesting/measurement in 2029).
• Several thousand RSUs remain subject to forfeiture per the filing (various grants list amounts in the ~12,000–15,000 range per grant in footnotes).
• Transaction codes: A = Award/Grant; F = Tax withholding (shares withheld to satisfy tax obligation). This is a cashless withholding, not an open-market sale.

Context

• These are compensation-related events (RSU grants and tax withholding) — routine for executives and typically administrative. Awards reflect potential future ownership if vesting and performance conditions are met; they are not a direct market purchase signal.
• Performance-based RSUs will only pay out based on achievement of stated goals and may be forfeited if targets or employment conditions aren’t met.
• For investors: purchases are usually more informative about insider conviction; award grants and tax-withholdings are standard compensation mechanics and shouldn’t be read alone as a buy/sell signal.
