Context

• This was an option exercise followed by an immediate open-market sale of shares (consistent with a cashless or sell-to-cover pattern). The sale was executed under a pre-established 10b5-1 plan, which indicates the trades were pre-planned rather than ad-hoc. The filing is factual and does not indicate insider intent.
