Stockholders' Equity Note [Abstract] |
Equity | Equity Common Stock Stock Repurchase Programs On December 12, 2024, the Edison International Board of Directors authorized a stock repurchase program effective February 20, 2025, for repurchase of up to $75 million of its common stock until February 18, 2026 ("2025 Repurchase Program"). The 2025 Repurchase Program will be used to offset dilution from common stock issued under Edison International's long-term incentive compensation programs and will be funded using Edison International's working capital. The timing and the amount of any repurchased common stock will be determined by Edison International's management based on their evaluation of market conditions and other factors. The 2025 Repurchase Program may be executed through various methods, including open market purchases, privately negotiated transactions, and other transactions in accordance with applicable securities laws. Any repurchased shares of common stock will be retired. The 2025 Repurchase Program does not obligate Edison International to acquire any particular amount of common stock, and it may be suspended or discontinued at any time at its discretion. During the three and nine months ended September 30, 2025, Edison International repurchased and retired 49,779 shares and 549,779 shares, respectively, for an average price per share of $54.40 and $58.56, respectively, under the 2025 Repurchase Program. As of September 30, 2025, $43 million authorized repurchase amount remained under the 2025 Share Repurchase Program.
