Key Details

• Transaction date and price: Mar 1, 2026 at $28.45 per share.
• Shares disposed: 9,789; total value $278,497.
• Transaction code: F — payment of exercise price or tax liability via share withholding.
• Shares owned after transaction: not reported in the provided filing extract.
• Filing timing: Report filed Mar 2, 2026 for a Mar 1 transaction (appears timely under Form 4 rules).

Context

• Code F typically means shares were withheld to cover taxes resulting from an option exercise or vesting of restricted stock/RSUs. This is a routine administrative step and not the same as a voluntary open‑market sale; it usually does not signal a change in the insider’s view of the company.
• For retail investors, purchases or open‑market buys are generally more informative than tax‑related withholdings.
