Key Details
- Transaction date and price: 2026-01-16, 8,406 shares at $44.48 each. Total proceeds ~$373,880.
- Reason: This was a mandatory "sell to cover" to satisfy tax withholding on RSUs that vested on 2026-01-15 (not a discretionary sale).
- Vesting/grant info: The sold shares relate to RSUs granted on Feb 14, 2022 and Feb 12, 2024; those RSU shares were fully vested.
- Holdings after the transaction: 14,898 shares of common stock and 85,660 RSUs (per filing footnote).
- Filing timeliness: Report filed 2026-01-21 for a 2026-01-16 transaction — outside the typical 2-business-day Form 4 window (appears late).
Context
"Sell to cover" transactions are routine tax-withholding sales when RSUs vest and do not necessarily indicate the insider's view of the company. The filing notes the sale was mandated by the issuer’s procedure and was not a voluntary, discretionary trade.
