Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On October 1, 2021, our Board authorized a share repurchase program of up to $4 billion of our outstanding common stock, enabling us to opportunistically return value to shareholders. The $4 billion authorization is effective for four years, beginning on January 1, 2022 and expiring on December 31, 2025, and does not require the purchase of any minimum number of shares. We did not repurchase any shares under this program during the second quarter of 2025. As of June 30, 2025, $1,810 million remained available for repurchase under the authorized share repurchase program.
