5. Earnings Per Share

(PPL)

Basic EPS is computed by dividing income available to PPL common shareowners by the weighted-average number of common shares outstanding during the applicable period. Diluted EPS is computed by dividing income available to PPL common shareowners by the weighted-average number of common shares outstanding, increased by the number of incremental shares that would be outstanding if potentially dilutive share-based payment awards were converted to common shares as calculated using the Two-Class Method or Treasury Stock Method. The If-Converted Method is applied to the Exchangeable Senior Notes due 2028 and 2030 (Exchangeable Notes) issued in February 2023 and November 2025.

Incremental non-participating securities that have a dilutive impact are detailed in the table below. In 2025, these securities include forward sales of PPL common stock issued through an ATM Program and the number of shares needed to settle the conversion premium on the Exchangeable Notes. The forward sale agreements are dilutive under the Treasury Stock Method to the extent the average stock price of PPL's common shares exceeds the forward sale price prescribed in the agreements. See Note 8 for additional information on the ATM Program and the Exchangeable Senior Notes due 2030 and Note 8 in PPL's Annual Report on Form 10-K for the year ended December 31, 2023 for additional information on the Exchangeable Notes due 2028.
