On March 9, 2026, Planet Fitness, Inc. (the “Company”) announced the departure of Jay Stasz, Chief Financial Officer, effective March 9, 2026. Mr. Stasz’s departure was not the result of any dispute or disagreement with the Company relating to reported financial statements and related financial results.

The Company also announced that Tom Fitzgerald, age 65, has been appointed as the Company’s interim Chief Financial Officer, effective March 9, 2026. Mr. Fitzgerald served as the Company’s Chief Financial Officer from January 2020 through November 14, 2024, after which he remained employed with the Company through December 31, 2024. He subsequently served in a consulting role with the Company periodically thereafter. Mr. Fitzgerald is a member of the board of Premier Franchise Management. He holds an MBA in Finance from Indiana University’s Kelley School of Business and a Bachelor’s degree in Finance from the University of Florida.

In connection with Mr. Fitzgerald’s appointment as interim Chief Financial Officer, on March 5, 2026, the Company and Mr. Fitzgerald entered into an employment agreement (the “Agreement”) with an initial term of 6 months (and up to three month-to-month extensions thereafter), pursuant to which Mr. Fitzgerald will receive a monthly salary of $250,000 per month.

The Agreement provides that Mr. Fitzgerald will not be eligible to participate in the Company’s Executive Severance & Change in Control Policy.
