Item 4 — Purpose of Transaction
Item 4 of the Schedule 13D is hereby further amended and supplemented by inserting the following paragraph after the last paragraph thereof: Since the filing of Amendment No. 14 on July 31, 2024, the aggregate number of shares of Common Stock outstanding decreased from 21,790,658 shares outstanding as of April 9, 2025, to 20,920,658 shares outstanding as of May 6, 2025, primarily as a result of the Issuer's purchase of 870,000 shares of its Common Stock on May 6, 2025, pursuant to a modified "Dutch Auction" tender offer, and additional purchases of shares of Common Stock by the Issuer under the terms of existing stock award agreements. No shares of Common Stock were tendered by the Reporting Persons in the tender offer. This decrease in the aggregate number of outstanding shares of Common Stock described in this Amendment No. 15, resulted in the increases in the percentages of outstanding shares of Common Stock beneficially owned by the Reporting Persons.
