Stock Repurchase Programs

On April 23, 2024, the Board authorized a stock repurchase program under which the Company may purchase up to $2,000.0 of its Common Stock during the three-year period ending on the close of business on April 28, 2027 (the “2024 Stock Repurchase Program”). The 2024 Stock Repurchase Program became effective on April 29, 2024. During the three months ended March 31, 2026, the Company repurchased 1.3 million shares of its Common Stock for $178.0 under the 2024 Stock Repurchase Program. All of the repurchased shares under the 2024 Stock Repurchase Program during the three months ended March 31, 2026 were retained in Treasury stock at the time of repurchase. From April 1, 2026 to April 28, 2026, the Company repurchased 0.3 million additional shares of its Common Stock for $44.2, and, as of April 29, 2026, the Company has remaining authorization to purchase up to $648.8 of its Common Stock under the 2024 Stock Repurchase Program. The timing and amount of any future repurchases will depend on a number of factors, such as the levels of cash generation from operations, the volume of stock options exercised by employees, cash requirements for acquisitions, dividends paid, economic and market conditions and the price of the Common Stock.
