Context

• This was an option exercise (code M). The withholding of 86 shares indicates a sell-to-cover/tax-withholding settlement (code F), not an open-market sale for profit-taking. Exercises are common for executives when options vest or when exercising grants; they represent conversion of derivative awards into stock rather than a market-directed buy or sell.
