### Footnotes:

(1) This purchase was executed through multiple trades at prices ranging from $6.92 to $6.99. The price reported above reflects the weighted average purchase price. The reporting person hereby undertakes to provide upon request to the Securities and Exchange Commission staff, the Issuer or a security holder of the Issuer, full information regarding the number of shares purchased at each separate price for all transactions reported on this Form 4.

(2) This Amendment to Form 4 is being filed to correct the number of shares of Common Stock shown as beneficially owned by the Rachel Lynn Shaw Trust following the purchases made on January 29, 2026 and January 30, 2026, and to include the number of shares of Common Stock owned directly by the reporting person.  In addition, the prior Form 4 filings filed by the reporting person on December 11, 2025, September 22, 2025, September 2, 2025, August 22, 2025 and July 17, 2025 also misstated the number of shares of Common Stock beneficially owned by the Rachel Lynn Shaw Trust and did not separately state the number of shares of Common Stock directly owned by the reporting person.

(3) (Continued from footnote 2) With respect to the Form 4 filed on December 11, 2025, the Rachel Lynn Shaw Trust owned the following: 28,763 shares of Common Stock following the purchase of 2,758 shares of Common Stock on December 9, 2025, and 30,078 shares of Common Stock following the purchase of 1,315 shares of Common Stock on December 10, 2025. With respect to the Form 4 filed on September 22, 2025, the Rachel Lynn Shaw Trust owned 26,005 shares of Common Stock following the purchase of 4,537 shares of Common Stock on September 19, 2025.  With respect to the Form 4 filed on September 2, 2025, the Rachel Lynn Shaw Trust owned 21,468 shares of Common Stock following the purchase of 3,500 shares of Common Stock on August 29, 2025.  With respect to the Form 4 filed on August 22, 2025, the Rachel Lynn Shaw Trust owned 17,968 shares of Common Stock following the purchase of 4,800 shares of Common Stock on August 21, 2025.

(4) (Continued from footnote 3) With respect to the Form 4 filed on July 17, 2025, the Rachel Lynn Shaw Trust owned the following: 12,368 shares of Common Stock following the purchase of 3,068 shares of Common Stock on July 15, 2025, 12,668 shares of Common Stock following the purchase of 300 shares of Common Stock on July 16, 2025, and 13,168 shares of Common Stock following the purchase of 500 shares of Common Stock on July 16, 2025.  The Form 4 filed on July 17, 2025 also incorrectly stated that the reporting person is a contingent residual beneficiary of the Rachel Lynn Shaw Trust. At all times from July 15, 2025 through March 3, 2026, the reporting person has directly owned 1,310,100 shares of Common Stock.

(5) The reporting person is the trustee of the Rachel Lynn Shaw Trust.
