Context
Tax-withholding disposals and sales under 10b5‑1 plans are routine and generally reflect tax obligations or pre-planned liquidity rather than a discretionary market-timing decision. The filing does not indicate an option exercise followed immediately by sale (no cashless exercise noted); instead, one action was tax withholding tied to vesting, and the other was a scheduled open‑market sale under a trading plan.
