• Shares owned after transaction: not specified in the Form 4 filing.
• Filing timeliness: Report filed 2026-05-26 for transactions on 2026-05-21 and 2026-05-22; filing appears timely (no late-filing flag reported).
• Codes explained: A = Award/grant of RSUs; F = shares withheld to satisfy tax withholding.

Context
RSU grants (code A) are an award/acquisition of future shares subject to vesting; the 2,321 RSUs granted here vest next year (May 21, 2027). The 565-share “disposition” is a routine tax-withholding action tied to the automatic vesting of 2,917 RSUs and is not an open-market sale — such withholdings are common and typically do not signal a change in insider sentiment.
