Item 8.01 Other Events.

Effective July 23, 2021, the board of directors of the Company approved an amendment to the Company’s stock repurchase program originally approved on October 17, 2019, as amended on March 4, 2020, (the “Program”) to increase the amount of the Company’s Class A common stock (“Common Stock”) that may be repurchased under the Program from a maximum of $180 million to a maximum of $276.5 million and to extend the Program’s termination date from October 31, 2021, to October 31, 2022 (unless terminated sooner). The Program will be executed in accordance with Rule 10b-18 under the Exchange Act. To date, the Company has repurchased approximately $126.5 million of its Common Stock under the Program, which permits the Company to repurchase shares of its Common Stock through open market and privately negotiated transactions or otherwise (including pursuant to a trading plan in accordance with Exchange Act Rule 10b5-1). The timing, pricing, and amount of any repurchases under the Program will be determined by the Company’s management at its discretion based on a variety of factors, including, but not limited to, trading volume and market price of the Common Stock, corporate considerations, the Company’s working capital and investment requirements, general market and economic conditions, and legal requirements. The Program does not obligate the Company to repurchase any Common Stock and may be modified, discontinued, or suspended at any time without prior notice.
