Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 2 footnotes

Footnote F1

Shares issuable upon vesting of restricted stock units granted to the reporting person pursuant to the Registrant's 2023 Equity and Incentive Plan. The restricted stock units vests on June 1, 2029, subject to the reporting person's continued employment through the vesting date.

Footnote F2

The number of shares reported herein reflects a correction to the reporting persons beneficial ownership. A Form 4 filed on March 18, 2026 incorrectly reported that 1,550 shares of common stock were withheld to satisfy tax withholding obligations upon vesting of a previously reported restricted stock award. The correct number of shares withheld for such purpose was 813.
