Item 4 — Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented as follows (which shall be in addition to the information previously included in the Schedule 13D): The Reporting Persons are making this filing to reflect material changes in ownership of the Issuer's Common Stock, due to Mr. Ganz's exercise of restricted stock units for 565,000 shares on July 24, 2026. Also, in light of the significant decline in the market price of the Issuer's stock since his retirement on March 2, 2026, Mr. Ganz has spoken with other stockholders of the Issuer regarding possible options to address this decline. Mr. Ganz does not believe that a "group" has been formed for purposes of Section 13 under the Securities Exchange Act of 1934 but is amending his prior Schedule 13D filing to disclose these conversations as a precautionary measure in the event they result in the formation of a "group.".
