- F2
This Form 4/A is being filed solely to correct the number of shares reported as sold on June 1, 2026 and the total number of shares owned following the transaction. Due to a broker administrative error, 585 fewer shares were sold than were required pursuant to the Reporting Person's Rule 10b5-1 trading plan. The error was corrected through the broker's error account, with the broker crediting the Reporting Person for the additional 585 shares at the applicable June 1, 2026 sale price and absorbing the cost of the correction. No additional open-market sale was effected in connection with the correction.
