Key Details

• Transaction date: 2026-06-11; Form 4 filed 2026-06-12 (appears to be timely).
• Award: 0.539 RSUs; acquisition price reported $0.00; total cash consideration reported $0.
• Post-transaction holdings: the filing does not disclose total shares beneficially owned after this entry.
• Footnotes: (1) each RSU represents a contingent right to one share; (2) dividend equivalent rights accrue with dividends and become exercisable proportionately with the RSUs; (3) RSUs are fully vested but actual share delivery is deferred until the first anniversary after the reporting person's separation from service on the Board.
• No indication of a 10b5-1 plan, sale, tax-withholding sell-to-cover, or late filing in this report.

Context
RSUs are a common form of compensation for directors and are derivative awards (not an open-market purchase). Although these RSUs are fully vested, delivery is subject to the timing rule tied to separation from board service, so the reporting person does not receive tradable shares immediately. The award size reported here (0.539 RSUs) is small and typically routine for administrative/compensation adjustments; it should be interpreted as a compensation grant rather than an active market purchase or sale.
