Six Flags Entertainment Corporation, now the combined company of Former Six Flags and Cedar Fair, uses this annual report to describe a transformed, highly leveraged regional park operator following a 2024 merger of equals. Cedar Fair is the accounting acquirer, so historical results largely reflect its operations until mid‑2024.
The company now runs 41 amusement and water parks and nine resort properties across North America, with about 70% of 2025 attendance and revenue concentrated in the second and third quarters. Management highlights significant risks from merger integration, a high fixed‑cost base, extreme weather and climate impacts, cybersecurity, and $5.2 billion of debt as of December 31, 2025. The workforce included about 4,225 full‑time employees at year‑end 2025, roughly 15% fewer than a year earlier due to post‑merger efficiency efforts, plus about 91,000 seasonal and part‑time employees.
