Context
- These entries show exercised options (transaction code M) followed by open‑market sales (S). When option exercises are immediately followed by market sales, it often reflects a cashless exercise or sales to cover exercise costs and tax withholding; here the filing explicitly notes a 10b5‑1 tax withholding instruction for RSU vesting. No inference should be made about insider sentiment beyond the record of purchases/exercises and sales — the filing is factual reporting of exercises and routine / planned sales.
