Footnotes from the filing
The issuer withheld shares of common stock that would have otherwise been issuable to the reporting person to satisfy the issuer's tax withholding obligations in connection with the vesting and settlement of the performance-based restricted stock units granted on March 1, 2023 and vested as of December 31, 2025 following the certification by the issuer's compensation committee of the applicable performance conditions for such performance-based restricted stock unit awards settling on March 1, 2026. The number of shares of common stock withheld was determined based on the closing price per share of the issuer's common stock on February 27, 2025.
