Key Details

• Transaction date: 2026-06-05; Filing date (Form 4): 2026-06-15.
• Transaction type/code: Award/Grant (A); derivative instrument (shares underlying an option).
• Amount: 15,000 shares; reported price: $0.00.
• Vesting: Shares underlying the option vest monthly over a one-year period from the grant date (footnote).
• Shares owned after transaction: Not disclosed in the Form 4.
• Timeliness: Form 4 was filed 10 days after the transaction date (typically Form 4 is due within 2 business days), so this filing appears late.

Context

• This is a compensation grant to a director (annual board award) and not a market purchase or sale. Such awards are routine and reflect compensation policy rather than a direct buy/sell signal. Because these are derivative awards that vest over time, they do not represent immediate ownership of freely tradable shares until vested (and any exercise conditions are met).
