Context
- The awards are RSUs (contingent rights to receive common stock). Footnote F1 notes 5,066 RSUs were certified as earned under the 2025 bonus plan and will vest on March 9, 2026 subject to continued service. Footnote F2 explains the 83,507 RSUs vest 20% on March 1, 2027 with the remainder vesting quarterly through March 1, 2031, subject to continued service. Footnote F3 confirms the 3,658-share disposition was a routine withholding by the issuer to satisfy tax withholding obligations — a common administrative step that does not necessarily signal an intent to sell stock for investment reasons.
