What Happened

The RSU settlements are recorded as exercise/conversion events at $0.00 (conversion of RSUs into shares).
To cover tax withholding obligations, the company withheld 162 shares on 2026-02-05 at $83.87 (worth $13,587) and 336 shares on 2026-02-06 at $90.29 (worth $30,337), for a total withholding value of $43,924. These withholdings are recorded as dispositions to satisfy tax liabilities.

Context

This was a routine RSU settlement with share withholding to cover tax liabilities (not an open-market sale or purchase). The conversions were recorded at $0 (typical for RSU settlement); the only cash-equivalent transactions reported were the share-withholding disposals to satisfy taxes.
