About
FirstEnergy Corp. is an Akron, Ohio-based regulated electric utility holding company — publicly traded on the New York Stock Exchange (NYSE: FE) as an S&P 500 Utilities component — providing electric transmission and distribution service to approximately 6 million customers across six states (Ohio, Pennsylvania, West Virginia, New Jersey, Maryland, New York) through regulated utility subsidiaries including Ohio Edison, Cleveland Electric Illuminating, Toledo Edison, Pennsylvania Power, The Illuminating Company, Monongahela Power, Potomac Edison, Jersey Central Power & Light, Met-Ed, Penn Power, and West Penn Power through approximately 12,000 employees. FirstEnergy is in the final stages of reputational and operational recovery from a historic corporate governance scandal: in 2020, FirstEnergy admitted to paying $60 million in bribes to Ohio utility regulators and state legislators (including former Ohio House Speaker Larry Householder) to secure passage of HB 6 — a $1.3 billion nuclear plant bailout law that was later repealed — resulting in criminal convictions, executive departures, shareholder class action settlements, and a $230 million DOJ deferred prosecution agreement. In fiscal year 2024, FirstEnergy reported revenues of approximately $13.5 billion, with the company executing CEO Brian Tierney's (joined 2023) strategy of rebuilding regulatory trust, improving operational performance, and executing the $26 billion capital plan (2024-2028) for grid modernization, electric vehicle infrastructure, and smart meter installation across the six-state service territory. FirstEnergy's 2021 divestiture of its competitive power generation business (FirstEnergy Solutions — renamed Evolent Energy Resources, including the Davis-Besse and Perry nuclear plants in Ohio) simplified FirstEnergy to a pure regulated utility — eliminating the commodity generation exposure that had distorted earnings and contributed to the improper HB 6 lobbying motivation.
