SHARE REPURCHASES

In May 2015, our Board of Directors (the “Board”) authorized a share repurchase program to repurchase up to $1.2 billion of our common stock. The Board authorized incremental share repurchases of up to an aggregate additional $5.8 billion of the Company’s common stock from February 2021 to September 2025. The Board also authorized incremental share repurchases of up to an additional $500 million in January 2026. The Company adopted its share repurchase plan with the goal of returning excess capital to shareholders in accordance with its capital allocation policy. The Company may repurchase its common stock from time-to-time in amounts, at prices and in the manner that the Company deems appropriate, subject to the availability of stock, prevailing market conditions, the trading price of the stock, the Company’s financial performance and other conditions. Repurchases may be made through open market purchases (which may include repurchase plans designed to comply with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended), accelerated share repurchases, private transactions or other transactions and will be funded by cash on hand and borrowings. Repurchases may also be made from time-to-time in connection with the settlement of the Company’s stock-based compensation awards. The table below summarizes the repurchases of our common stock during the three months ended December 31, 2025 pursuant to our share repurchase program and the settlement of stock-based compensation awards.
