Context This was not an open-market purchase or voluntary sale but the settlement of performance-based equity (PSUs) that vested after the company met 2025 targets. The tax withholding (code F) is routine: companies often withhold or sell a portion of vested shares to cover withholding taxes. For retail investors, awards and routine tax withholdings convey that compensation-based equity was issued, but they do not by themselves indicate insider buying or selling intentions in the market.
