On November 4, 2022, the Company's Board of Directors approved an authorization to repurchase up to $1.5 billion of the Company's common stock (the “2022 Repurchase Authorization”). As of September 30, 2024, the Company had repurchased and retired 30.0 million shares of common stock for the full $1.5 billion approved under the 2022 Repurchase Authorization. All shares repurchased under the 2022 Repurchase Authorization were retired and accounted for as a reduction to stockholders’ equity in the Consolidated Balance Sheets and treated as a repurchase of common stock for purposes of calculating earnings per share as of the applicable settlement dates. During the six months ended March 31,
2025, the Company paid the remaining excise tax due in connection with the 2022 Repurchase Authorization, totaling $11.4 million.
On December 8, 2025, the Board of Directors approved a share repurchase program authorizing the repurchase of up to $250 million of the Company’s common stock through December 31, 2028 (the “2025 Repurchase Program”). Repurchases under the 2025 Repurchase Program may be made in the open market or through privately negotiated transactions (including under an accelerated share repurchase agreement), or by other means, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, subject to market and business conditions, legal requirements, and other factors. The Company is not obligated to acquire any particular amount of common stock under the 2025 Repurchase Program, and share repurchases may be commenced or suspended at any time at the Company’s discretion. As of the date of issuance of these Condensed Consolidated Financial Statements, the Company has not repurchased any shares of its common stock under the 2025 Repurchase Program.
