Key Details

• Transaction date: 2026-01-26 (Form 4 filed 2026-01-28 — filing appears timely).
• Option exercise: 5,851 shares at $60.07 (total $351,470).
• Tax withholding/disposition: 2,303 shares at $60.07 (total $138,341) — shares withheld to satisfy tax obligations (footnote F1).
• Awards: 202,009 RSUs at $59.81 (reported value ~$12,082,158) and 29,798 RSUs at $0 (includes dividend-equivalent reinvestment).
• Vesting/derivative notes: RSUs convert 1-for-1 to common stock (F3); RSUs vest in three annual installments (33%, 33%, 34%) beginning on the grant date (F2, F4); the option was 100% vested (F6).
• Shares owned after transaction: not reported in the excerpt provided.
• Filing timeliness: filed two days after the transactions (appears timely, not flagged late).

Context

• The large RSU grant is an acquisition of restricted stock units (award), not an immediate open-market purchase — these shares are subject to vesting and convert to common shares over time. The option exercise involved derivative activity; the filing shows both the issuance from exercise and shares withheld/ disposed to cover taxes — tax withholding is common and does not necessarily indicate an open-market sale. All amounts and footnotes are taken directly from the Form 4 entries; no motive or future trading intent is implied.
