CHARLOTTE - Six Flags Entertainment Corporation (NYSE:FUN), North America’s largest regional amusement park operator, announced Monday the appointment of John Reilly as President and Chief Executive Officer, effective December 8, 2025. The announcement comes as the company’s stock has declined over 70% in the past year, trading near its 52-week low of $12.51, according to InvestingPro data.
Reilly, who brings more than 30 years of experience in the amusement and recreation industry, will succeed Richard A. Zimmerman, who is stepping down from his leadership role and board position as previously announced in August.
The incoming CEO most recently served as Chief Executive Officer of Palace Entertainment U.S. and Group Chief Operating Officer at Parques Reunidos. His prior experience includes roles as interim Chief Executive Officer and Chief Operating Officer at SeaWorld Parks and Entertainment.
"I am honored to serve as Six Flags’ next President and Chief Executive Officer and look forward to working with the Board, leadership team, and talented associates to deliver results," Reilly said in the press release statement.
Marilyn Spiegel, Chair-elect of the Six Flags Board, noted that Reilly is joining at a critical moment following the merger of Six Flags and Cedar Fair last year. The company operates 26 amusement parks, 15 water parks and nine resort properties across 16 states in the U.S., Canada and Mexico.
Zimmerman, the outgoing CEO, expressed confidence in his successor, stating that Reilly’s leadership track record and passion for creating memorable guest experiences make him the ideal choice for the company’s next leader.
Reilly earned an MBA from the University of Miami and a B.A. from William & Mary.
