Key Details

• Transaction date: March 20, 2026 (reported on Form 4 filed March 24, 2026). The filing does not indicate a late reporting flag.
• Derivative conversion/exercise (code M): 30,274 shares acquired at $0.00 (vesting/conversion of PRSUs).
• Tax withholding (code F): 15,049 shares surrendered at $31.00 per share for $466,519.
• Net shares retained from this event: 30,274 acquired − 15,049 surrendered = 15,225 shares.
• Footnote: The PRSUs were granted March 13, 2023 and were earned at 172.5% of the original grant based on three-year relative total shareholder return vs. Russell 2000 criteria.
• The filing shows routine tax-withholding share surrender (not an open-market sale).

Context This was not an open-market buy or sale. It reflects the vesting/settlement of performance-based RSUs (a common form of executive compensation) and routine share surrender to meet tax obligations. Such transactions represent compensation realization rather than an explicit directional bet by the insider.
