Context

• This was a grant of a derivative award (described in the filing as an option) tied to continued service; it does not represent an immediate purchase or sale of shares. If and when the award vests and is exercised, subsequent Form 4 filings would disclose any exercise, sale, or ownership changes. Compensation grants are common for directors and are not, by themselves, a direct indicator of personal market buying or selling.
