Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 2 footnotes

Footnote F1

Payment of tax liability by withholding securities incident to vesting of performance stock units.

Footnote F2

Due to an administrative error, the Form 4 filed on February 21, 2025 inadvertently reflected an incorrect amount of shares withheld for the payment of tax liability. As reflected in this amendment, the correct number of shares withheld on February 20, 2025 was 3,189 shares. As a result, the reporting person's beneficial ownership in Table I, Column 5 was underreported by 1,158 shares in the original February 21, 2025 filing and in the subsequent Forms 4 filed on February 28, 2025, March 4, 2025, March 18, 2025, June 24, 2025, November 21, 2025, February 20, 2026, and March 3, 2026.
