Item 8.01. Other Events

On November 5, 2026, the Company announced that the Board has authorized an additional repurchase of up to an aggregate of $100 million of the Company’s outstanding common stock (the “Repurchase Program”). This Repurchase Program is in addition to the $100 million repurchase program that was announced on April 30, 2026, and the $150 million repurchase program that was announced on August 26, 2026.

Any share repurchases under the Repurchase Program will be made in accordance with applicable securities laws in either open market or privately negotiated transactions. The Company may also, from time to time, enter into Rule 10b-18 and/or Rule 10b5-1 plans to facilitate repurchases of its shares under the Repurchase Program. The method, timing and amount of shares repurchased under the Repurchase Program will depend on several factors, including capital and liquidity requirements, market conditions and alternative uses for cash. The Repurchase Program does not obligate the Company to acquire any particular amount of its common stock, and the Repurchase Program may be modified, suspended or discontinued at any time.
