What Happened?

On July 1, 2024, Six Flags completed a merger with Cedar Fair to create North America’s largest regional amusement park operator with a portfolio of approximately 40 amusement parks, water parks, and resort properties (the “Merger”).

On August 6, 2025, Six Flags released its second quarter 2025 financial results, revealing revenue of just $930 million and adjusted EBITDA of $243 million – well below consensus estimates. The Company also revealed its debt-to-earnings leverage ratio had increased to 6.2x, causing it to consider the “divestiture of non-core assets.”

The Company slashed its 2025 EBITDA guidance by $215 million at the midpoint and announced that Richard Zimmerman, Six Flag’s CEO and former Cider Fair CEO, was stepping down.

While Six Flags cited “weather” for the poor results, several analysts found it more likely that rising costs and the inability to achieve certain Merger benefits were to blame.

On the Merger closing date, July 1, 2024, Six Flags stock traded above $55 per share. The price of Six Flags stock subsequently fell as low as $20 per share, a nearly 64% decline, thereby injuring investors.
