Insider ownership and standard executive awards, with a late initial filing noted.

The reporting shows direct ownership of 138,259 common shares plus multiple non-qualified stock option grants and restricted stock units that vest over multi-year schedules, aligning compensation with continued service.

These equity awards create deferred incentives tied to tenure; key dates include RSU vesting on 03/14/2026, 03/14/2027, and 05/20/2027, and option exercise windows through 05/20/2035. The late filing was attributed to administrative delays.
