9. Stockholders’ Equity

Share Repurchases

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”). During the six months ended March 31, 2024, the Company repurchased 3.5 million shares of common stock for $186.8 million (excluding fees, commissions, and excise tax) under this 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, accounted for as a reduction to stockholders’ equity in the Condensed Consolidated Balance Sheets and treated as a repurchase of common stock for purposes of calculating earnings per share as of the applicable settlement dates. No additional repurchase authorization has been approved and as such there were no shares repurchased during the six months ended March 31, 2025. 

Effective  January 1, 2023, all corporate share repurchases are subject to a one percent excise tax on the value of the repurchase, net of share issuances, subject to certain exclusions. The excise tax was part of The Inflation Reduction Act passed by the U.S. government in 2022. The Company's accrual for excise tax related to share repurchases is considered an additional cost of the share repurchases and a reduction to stockholders’ equity in the Condensed Consolidated Balance Sheets. 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.
