Overview
- John Reilly takes over as president and CEO on Dec. 8, 2025, joining the board as Richard A. Zimmerman exits the role and the board the same day.
- Six Flags’ board said a formal search identified Reilly as the operator to revive underperforming parks and unlock strengths of the merged Six Flags–Cedar Fair portfolio.
- Reilly brings more than three decades of experience, including top roles at Palace Entertainment U.S., Parques Reunidos, and SeaWorld Parks & Entertainment.
- Financial pressures persist: reporting cites a share-price slide of more than 70% over roughly 16 months, third‑quarter revenue down 2% year over year to $1.32 billion, EBITDA slightly lower, and October attendance off 11%.
- Portfolio actions are accelerating, with Six Flags America closed in November and California’s Great America scheduled to wind down later this decade, as executives prioritize high‑return parks, consider monetizing others, and engage investors including Jana Partners and Travis Kelce on branding and operational plans.
