The Reporting Persons purchased the Shares based on their belief that the Shares, when purchased, constituted an attractive investment opportunity.

On October 25, 2023, the Reporting Persons delivered a letter (the “Offer Letter”) to the Board of Directors (the “Board”) of the Issuer conveying a proposal to acquire 100% of the Issuer’s outstanding Shares at a price equal to $1.00 per share in cash, representing a premium of approximately 67% over the closing price as of the close of business on October 25, 2023 (the “Proposal”). The Reporting Persons have submitted the Proposal to the Board in order to facilitate constructive discussions, with the goal of entering into a mutually agreeable transaction that is in the best interests of all stockholders. A copy of the Offer Letter is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

 

The Reporting Persons do not have any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein. Depending on various factors including, without limitation, the Issuer’s financial position, results and strategic direction, actions taken by the Issuer’s management and the Board, other investment opportunities available to the Reporting Persons, the price levels of the Shares, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate including, without limitation, engaging in communications and information exchanges with the Issuer’s management and Board, engaging in discussions with shareholders of the Issuer or other third parties about the Issuer and the Reporting Persons’ investment, making recommendations concerning changes to the Issuer’s operations, governance or capitalization, potential business combinations or dispositions involving the Issuer or certain of its businesses, or suggestions for improving the Issuer’s financial and/or operational performance, acquiring additional Shares, disposing of some or all of Shares, or changing their intention with respect to any and all matters referred to in Item 4.
