Footnotes from the filing
Represents restricted stock units ("RSUs") issued to the reporting person. Each RSU represents a contingent right to receive one share of the registrant's common stock.
Due to an administrative error, the total number of shares beneficially owned by the reporting person was incorrectly reported as 55,627 shares on the Form 4 filed on February 25, 2025. The correct total should have been 22,217 shares. The total shares beneficially owned as reported on this form reflects a correction of that error.
