Based on the Reporting Person's review of publicly available information, the Reporting Person expressed its willingness to propose an acquisition price in the range of $5.61 to $7.00 per share in cash, which is at least 50% above the closing price of $3.74 on October 29, 2026. The Reporting Person stated that it is open to allowing other shareholders to participate in a transaction alongside the Reporting Person, with the Reporting Person acquiring the majority interest, with the scope of such participation determined through the Board's strategic process. The Reporting Person noted that ultimately it would seek a waiver of the Issuer's Stockholder Rights Agreement, dated October 12, 2026, so it is able to work with other interested shareholders. The Reporting Person highlighted its prior engagement with the Board and intention to continue to work together in a constructive manner toward an outcome that is in the best interests of all shareholders and other stakeholders, and the Reporting Person's track record delivering substantial value at other portfolio companies. A copy of the Letter is attached hereto as Exhibit 99.1 and incorporated herein by reference. Item 5(c) is hereby amended and restated to read as follows: There have been no transactions in the Shares of the Issuer by the Reporting Person since the filing of Amendment No. 3 to the Schedule 13D. Item 7 is hereby amended to add the following exhibit: 99.1 - Letter to Board of Directors, dated October 30, 2026 Fund 1 Investments, LLC /s/ Benjamin C. Cable 10/30/2026
