ENTERGY ARKANSAS, LLC

U.S. Securities and Exchange Commission Investigation

The Staff of the Division of Enforcement of the U.S. Securities and Exchange Commission conducted an investigation regarding Entergy’s processes and controls relating to its accounting for materials and supplies inventory. In December 2024, Entergy reached a settlement with the SEC to resolve the previously disclosed SEC investigation into Entergy’s internal controls and books and records concerning potential surplus materials and supplies inventory. Under the settlement terms, in which Entergy neither admitted nor denied the SEC’s allegations, Entergy consented to the entry of an injunction, paid a $12 million civil penalty, which was accrued in 2024 and paid in January 2025, and agreed to engage a consultant to conduct an assessment and make recommendations concerning Entergy’s internal controls related to the accounting for surplus materials and supplies. In September 2025 the independent consultant completed its assessment and submitted a report to Entergy and the SEC. Entergy has implemented the independent consultant’s recommendations and the independent consultant will conduct a follow-up audit in December 2026.
