Dorrell, et al. v. Constellation Energy, et al. Antitrust Class Action Litigation

On July 11, 2025, an antitrust class action lawsuit was filed in the United States District Court for the District of Maryland on behalf of a putative class against Entergy Corporation, 26 other entities alleged to own and/or operate commercial nuclear power plants in the United States (together with Entergy Corporation, the “nuclear defendants”), and two consulting companies. The class action complaint purports to be brought on behalf of all persons employed in nuclear power generation by the nuclear defendants and their subsidiaries and related entities in the United States from May 1, 2003 to the present. The plaintiffs primarily allege that the nuclear defendants, together with the consulting company defendants, violated Section 1 of the Sherman Act, 15 U.S. Code Chapter 1 by conspiring to suppress compensation and exchange collective bargaining agreement and wage information through a trade group, a consulting firm, and through direct communications, including attendance at conferences, from May 2003 to the present. The plaintiffs are seeking unspecified monetary damages, including treble damages, interest, injunctive relief, attorney’s fees, and costs. Entergy Corporation is evaluating the complaint.
