Six Flags Entertainment's top finance executive, Brian Witherow, is departing along with two other executives, as the amusement-park operator continues to overhaul its C-suite amid pressure from activist investors.

Witherow, who has been chief financial officer since the 2024 merger of Six Flags and Cedar Fair, is stepping down on Friday, the Charlotte, N.C., company said, adding that it has already identified several potential successors.

Prior to the merger, Witherow had been Cedar Fair's finance chief since 2012.

Six Flags said Dave Hoffman, its chief accounting officer, will serve as interim finance lead during the transition.

Six Flags is also parting ways with Christian Dieckmann, its chief commercial officer, and Brian Nurse, its chief legal and compliance officer.

The latest executive changes come after Six Flags last month brought in technology investor and veteran entertainment executive Richard Haddrill as executive chairman and late last year named industry veteran John Reilly as its new chief executive.

Activist investors have been pushing for changes at Six Flags.

Hedge fund Jana Partners has urged the company to engage with potential buyers, while Land & Buildings Investment Management has called on Six Flags to spin out or sell its real estate in an effort to boost its share price.

Six Flags also said it is separating the duties of chief commercial officer into two roles.

The company said Amy Martin Ziegenfuss, who has been serving as marketing chief for Carnival Cruise Line, will join as chief marketing officer on June 3, while Chris Meyering, its vice president of revenue management, will become senior vice president of commercial.

Six Flags said Christopher Bennett, a partner at the international law firm Dentons, will join as chief legal and compliance officer on June 3.
