Key Details

• Transaction date: 2026-05-28; Form 4 filed 2026-06-01 (timely filing). Transaction code: A (award/grant).
• Shares granted: 3,736 RSUs; reported acquisition price: $0.00 per share.
• Shares owned after the transaction: not specified in the filing.
• Vesting (footnote): The award vests in four equal installments on the last day of each fiscal quarter, with the first vesting on 2026-06-30, provided Partin remains a board member on each vesting date.
• No sale or exercise occurred—this is a compensation award, not a market purchase or disposition.

Context
RSUs are a form of compensation that convert to actual shares only as they vest; they do not represent an immediate cash transaction or a signal of buying/selling. Because continued board service is required for vesting, shares will be delivered over time if the director remains in position.
