Key Details

• Transaction date: 2026-06-17; Form 4 filed: 2026-06-18 (timely).
• Transaction type/code: Grant/Award (A); 2,745.5 RSUs acquired at $0.00.
• Reported value: $0 (RSUs are compensation-based, no cash paid).
• Shares owned after transaction: Not specified in the provided filing excerpt.
• Footnote: RSUs are granted under the issuer’s Incentive Plan and deferred under the Deferred Compensation Plan for Non-Employee Directors. RSUs either vest immediately or on the one-year anniversary but remain deferred; each RSU converts to one common share upon the earlier of the reporting person’s death or disability, or cessation of board service.

Context

• This transaction is a standard director compensation grant and does not involve a market purchase or sale. Because the RSUs are deferred, they represent a future right to shares rather than immediate ownership of tradable stock. The timely filing indicates the report was submitted promptly.
