NRG Energy Announces Launch of Secondary Common Stock Offering
HOUSTON—March 2, 2026—NRG Energy, Inc. (NYSE: NRG) announced today the launch of an underwritten public offering of 12,300,000 shares of its common stock held by certain affiliates of LS Power (the “Selling Stockholders”), subject to market and other conditions (the “Secondary Offering”). These shares are part of the consideration the Selling Stockholders received from NRG in connection with the recently closed acquisition of the LS Power portfolio entities on January 30, 2026. NRG will not receive any proceeds from the sale of the shares by the Selling Stockholders. The Selling Stockholders have also granted the underwriters a 30-day option to purchase up to an additional 1,845,000 shares of common stock.
Barclays and Citigroup are acting as joint book-running managers for the Secondary Offering.
In addition, NRG has entered into a stock purchase agreement with the Selling Stockholders to repurchase $300 million of its common stock in a private transaction at the price per share equal to the public offering price (the “Share Repurchase”). The Share Repurchase will be made pursuant to NRG’s existing stock repurchase program approved by its Board of Directors. The closing of the Share Repurchase is expected to be concurrent with the closing of the Secondary Offering. The completion of the Share Repurchase is conditioned upon the completion of the Secondary Offering, and subject to customary closing conditions. The completion of the Secondary Offering is not conditioned upon the completion of the Share Repurchase.
