Everest Group, Ltd. (NYSE: EG) faces a securities class action lawsuit alleging the company overstated the adequacy of its casualty reserves prior to recording approximately $2.2 billion in charges between January and October 2025. The complaint asserts that despite assurances regarding strengthened underwriting and adequate pricing for accident years 2020 through 2023, the insurer maintained a book concentrated in high-risk lines that was significantly under-reserved, thereby understating liabilities and overstating earnings. The litigation centers on two major reserve charges: $1.7 billion recorded in January 2025 and an additional $478 million in October 2025 following further adverse development from accident years 2022 through 2024. The lawsuit claims that the initial charge was presented as a resolution to prior issues, yet subsequent deterioration continued, leading S&P to revise its outlook on Everest to negative immediately after the first disclosure. The class action covers shareholders who purchased or acquired EG common stock between February 8, 2024, and October 27, 2025. The filing alleges that senior executives certified financial disclosures under Sarbanes-Oxley while misleading investors about the company's reserve adequacy. Shares of Everest fell 11.4% in a single session following the final disclosure of adverse development, highlighting the market reaction to the alleged misstatements. The case is filed in the United States District Court for the Southern District of New York and seeks recovery for institutional investors, pension funds, and asset managers who held EG stock during the class period. The complaint names Everest Group, Ltd. and individual senior executives as defendants, alleging they made public statements or signed SEC filings that contained material misrepresentations regarding the company's financial stability and reserve levels.
