PHILADELPHIA, Dec. 10, 2025 /PRNewswire/ — National plaintiffs’ law firm Berger Montague PC announces that a class action lawsuit against Six Flags Entertainment Corp. (NYSE: FUN) (“Six Flags” or the “Company”) has been filed on behalf of investors who purchased or acquired Six Flags shares during the period of July 1, 2024 through November 5, 2025 (the “Class Period”), including in connection with the merger between Six Flags and Cedar Fair L.P. (the “Merger”).
Investor Deadline: Investors who purchased Six Flags securities during the Class Period may, no later than January 5, 2026, seek to be appointed as a lead plaintiff representative of the class. To learn your rights, CLICK HERE.
Six Flags, headquartered in Arlington, Texas, operates one of the largest theme and water park networks in North America.
As alleged in the lawsuit, the Merger registration statement failed to accurately convey Six Flags’ true operational and capital needs. Despite public claims of major investments, Six Flags had, in fact, suffered from years of underinvestment, requiring significant spending to maintain market share. According to the complaint, undisclosed capital requirements conflicted with the Merger’s stated rationale.
When the Merger closed on July 1, 2024, Six Flags’ stock traded above $55 per share, later falling to as low as $20, a nearly 64% decline.
