A securities class action lawsuit has been filed against Six Flags Entertainment Corporation and certain executives, alleging that the company failed to disclose material information in connection with the July 1, 2024 merger with Cedar Fair. The lawsuit claims that Six Flags misrepresented its financial health by not revealing chronic underinvestment in its parks, the need for significant additional capital expenditures, and the negative impact of aggressive cost-cutting measures on operations and guest experience. Investors who purchased company shares tied to the merger's registration statement and prospectus and suffered substantial losses have until January 5, 2026 to seek appointment as lead plaintiff in the case, which is pending in the United States District Court for the Northern District of Ohio.
