Key Details

• Transaction date: 2026-05-21; Form 4 filed: 2026-05-22 (appears timely).
• Shares granted: 135; Price per share: $0.00; Reported total value: $0.

• Shares owned after transaction: not specified in this Form 4.
• Transaction type: A (award/grant/other acquisition); not a sale or option exercise.

Context

• Director share awards are a common form of non-cash compensation and do not necessarily signal a director’s market view. Because the grant was reported at $0, this reflects an award rather than a purchase; there is no indication these shares were immediately sold.
