CHARLOTTE, N.C.--(BUSINESS WIRE)--Six Flags Entertainment Corporation (NYSE: FUN) (“Six Flags” or the “Company”), North America’s largest regional amusement park operator, today announced the appointment of Richard “Dick” Haddrill as Executive Chairman of the Six Flags Board of Directors, effective immediately. With Mr. Haddrill’s appointment, Marilyn Spiegel will serve as Lead Independent Director.

Over the last several months, Six Flags has taken decisive actions to improve performance, including appointing John Reilly as CEO in December 2025, accelerating the Company’s portfolio optimization and improving its capital structure.

Haddrill is a renowned public company executive with decades of experience in the entertainment and leisure industries. He previously served as Executive Vice Chairman of the Board of Scientific Games (now Light & Wonder), a leading provider of gaming and entertainment solutions and services. Before that, he served as Chief Executive Officer of Bally Technologies, where he led the company through significant growth and strategic transformation, culminating in its acquisition by Scientific Games. As Executive Chairman at Six Flags, Haddrill will focus on improving profitability while implementing strategic actions to drive long-term growth.

“Dick is a proven leader with a strong track record of delivering outsized returns for shareholders,” said Spiegel. “His strategic mindset, steady leadership, and decades of experience scaling and optimizing businesses will be invaluable as we continue to improve performance across the portfolio and enhance the guest experience. Dick’s appointment reflects the Board’s commitment to thoughtful refreshment to effectively oversee management’s efforts to unlock the full value of Six Flags’ world-class portfolio.”

“On behalf of the management team and associates, we welcome Dick to Six Flags,” said Reilly. “We look forward to working with him as we sharpen our focus on profitability and drive value creation for our guests and shareholders.”

“Six Flags is an incredible business, and I believe in the steps John Reilly and the management team are taking to strengthen execution and realize the full potential of the irreplaceable Six Flags portfolio,” said Haddrill. “I am excited to work closely with John, the rest of the Six Flags Board, and the management team to continue building on their progress.”

With Haddrill’s addition, the Board will temporarily expand to 11 members. As previously disclosed, Jennifer Mason will not stand for re-election when her term expires at the Company’s 2026 Annual Meeting of Stockholders, at which point the Board size will revert to 10 members.
