Stock Repurchase Programs
In May 2025 our board of directors authorized a $1.5 billion stock repurchase program (the “Repurchase Program”). This authorization allows us to repurchase shares of our common stock that will be funded from working capital. Repurchases may be made at management's discretion from time to time on the open market, through privately negotiated transactions, transactions structured through investment banking institutions, block purchases, trading plans under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or a combination of the foregoing. The Repurchase Program does not obligate us to acquire any of our common stock and may be suspended or discontinued by the Company at any time without prior notice. We did not repurchase any shares during the three months ended March 31, 2026. As of March 31, 2026, the remaining authorized amount for repurchases under the Repurchase Program was $817.9 million.
