This Amendment amends and supplements Item 4 of the Original Schedule 13D by adding the following: Revised Non-Binding Proposal On October 10, 2025, the Consortium jointly submitted a best and final non-binding proposal (the "Revised Proposal") to the special committee of the Board increasing the price per Share that the Consortium is proposing to pay to acquire all of the Shares (on a fully diluted basis) of the Issuer not presently owned by the Consortium Members in the Proposed Transaction to $8.15 per Share. The Revised Proposal is the Consortium's best and final non-binding offer. The Revised Proposal is non-binding, and no agreement, arrangement or understanding between the Consortium or any Consortium Members, on the one hand, and the Issuer, on the other hand, relating to the Revised Proposal, the Proposed Transaction or any other transaction will be created until such time as definitive agreements for the Proposed Transaction have been executed and delivered. References to, and descriptions of, the Revised Proposal in this Schedule 13D are qualified in their entirety by the terms of the Revised Proposal, a copy of which is attached hereto as Exhibit 99.9 and is incorporated in its entirety into this Item 4.
