In February 2024, the Company announced that its board of directors approved a share repurchase program to purchase up to $6.0 billion of the Company’s Class A common stock.

Share repurchases under the share repurchase program may be made through a variety of methods, such as open market purchases, privately negotiated transactions, block trades, or accelerated share repurchase transactions, or by any combination of such methods. Any such repurchases will be made from time to time subject to market and economic conditions, applicable legal requirements, and other relevant factors. The share repurchase program does not obligate the Company to repurchase any specific number of shares and may be modified, suspended, or terminated at any time at the Company’s discretion.

During the three months ended March 31, 2025, the Company repurchased and subsequently retired 6.1 million shares of Class A common stock for $807 million. As of March 31, 2025, the Company had $2.5 billion available to repurchase shares of Class A common stock under its share repurchase program. During the three months ended March 31, 2024, the Company repurchased and subsequently retired 4.7 million shares of Class A common stock for $750 million, which completed the repurchases authorized under the share repurchase program announced in May 2023.
