The press release referred to above also announced that the Company’s Board of Directors approved an additional $40 million to its share repurchase plan authorization and the Company plans to launch a modified “Dutch auction” tender offer on November 5, 2025 to purchase up to $40 million in value of its common stock, at a price ranging from $18.30 to $21.00. Additional Information Regarding the Tender Offer The tender offer described above has not yet commenced, and there can be no assurances that the Company will commence the tender offer on the terms described or at all. On the commencement date of the tender offer, the Company will file a tender offer statement on Schedule TO, including an offer to purchase, letter of transmittal and other tender offer materials, with the SEC. The tender offer will only be made pursuant to the offer to purchase, the related letter of transmittal and the other tender offer materials filed as part of the Schedule TO.
