The world's largest multi-brand restaurant franchisee is now also one of the largest gym operators in the United States. Flynn Group, the operator of more than 1,200 Pizza Huts, 460 Applebee's, 300 Taco Bells, and hundreds of Arby's, Panera, and Wendy's locations, announced on that it has acquired Grand Fitness Partners and its 98 Planet Fitness gyms across five states. The deal, covered by Franchise Times this week, tripled Flynn's Planet Fitness portfolio overnight and elevates the company to the fifth-largest franchisee in the Planet Fitness system at 141 total clubs.
Why a Restaurant Giant Wants Gyms
Flynn Group's move into fitness started in 2023 with the acquisition of Alder Partners, a 37-unit Planet Fitness franchisee. At the time, CEO Greg Flynn told Franchise Times he would be "surprised and disappointed" if Planet Fitness did not mirror the size of his other brand portfolios within five years. The Grand Fitness deal is the most concrete step toward fulfilling that prediction, and Flynn was blunt about his intent to continue acquiring.
"We made what for us was a modest step into it with Alder, but it was always our intention to continue to grow so that it became a very meaningful and relevant part of our overall portfolio."Greg Flynn, Founder and CEO, Flynn Group
The strategic logic is the same logic that made Flynn Group dominant in restaurants: franchise-level operational efficiency applied to proven consumer brands at scale. Flynn's restaurant business did nearly $5 billion in sales last year, and the company has developed the back-office, real estate, labor management, and capital structure capabilities to run large geographically diversified franchisee portfolios efficiently. Those capabilities translate surprisingly well to Planet Fitness's operating model, which shares the real estate intensity, shift-labor structure, and local market dynamics of a quick-service restaurant chain.

The GLP-1 Question That Made This Deal Smarter
A year ago, gym operators were publicly worried that GLP-1 weight-loss drugs like Ozempic and Wegovy would gut their membership base. The fear was straightforward: if pharmacology delivered weight loss more reliably than exercise, why would people keep paying for gym memberships? Early consumer research muddied that story. GLP-1 users have turned out to be more likely to join gyms, not less, because maintaining muscle mass during rapid weight loss has become a recognized health priority, and resistance training is the most accessible way to do it.
Planet Fitness has leaned into this shift aggressively. In late 2025, the chain launched a Perks partnership with Ro, the direct-to-consumer telehealth platform that offers access to GLP-1 weight-loss drugs. The partnership is explicitly designed to position Planet Fitness as the fitness complement to pharmacological weight loss rather than a competitor. The chain has also been adjusting its equipment mix to add strength training stations and reduce cardio-only floor space.
"It's a wonderful business. The basic business model is great. It's general-purpose gyms, which I like because they're not so specialized. They have very broad appeal. And I think GLP-1s are going to prove to be a nice tailwind for the industry."Greg Flynn, Founder and CEO, Flynn Group
Flynn's framing is notable. An operator of his scale does not describe a structural industry risk as a "nice tailwind" without serious conviction behind it. The math is that Planet Fitness's low monthly price point ($15 to $25 for most members) stays accessible to people on GLP-1s who are specifically looking for a way to preserve muscle, and the chain's "Judgement Free Zone" positioning fits the demographic that is starting weight-loss journeys for the first time.
The Unit Economics That Made Grand Fitness Worth Buying
Planet Fitness franchise economics have become unusually strong by the standards of the low-price gym category. The chain's 2024 Franchise Disclosure Document reported that the top third of franchised clubs averaged $2.6 million in annual sales (measured as electronic funds transfer revenue, essentially membership charges). The middle third averaged $1.8 million, and the bottom third $1.2 million. Those numbers reflect a category where fixed costs are high but marginal member revenue is clean recurring subscription income.
Stan DeMartinis Jr., who founded Alder Partners and now leads Flynn Planet Fitness after the 2023 acquisition, described the Grand Fitness portfolio in terms that suggest it sits solidly in the top third of the system.
"The business is immediately accretive to the overall P&L, day one. What I like about the Grand opportunity is a lot of the stores that we're doing out in California are one-off markets. When you're first to market, you build the right footprint and you give the consumer what they need, it really makes it really, really difficult for the competition to come in."Stan DeMartinis Jr., President, Flynn Planet Fitness
The California expansion is the strategically meaningful piece. Grand Fitness brought Flynn into California, Florida, New Jersey, Pennsylvania, and Virginia, adding five new state markets to a previous footprint concentrated in Atlanta and Boston. California specifically gives Flynn Group "designated market area" (DMA) control in multiple metros, which allows the kind of geographic saturation that creates real competitive moats against new entrants.
The Private Equity Handoff
Grand Fitness had been owned by middle-market private equity firm HGGC since 2021, when the portfolio was 42 Planet Fitness locations. HGGC roughly doubled the club count during its ownership and exited at an undisclosed valuation, with prior majority owner Monogram Capital Partners also selling its remaining stake.
That exit pattern is the standard private-equity playbook: buy a multi-unit franchisee, grow it aggressively through acquisitions and new builds over four to seven years, then sell to a strategic operator or a larger financial buyer. HGGC's timing on the sale is a soft signal that the Planet Fitness franchise category has matured enough that the growth phase of multiple rolling acquisitions is giving way to a consolidation phase where a small number of very large franchisees will dominate.
For consumers, the ownership change may be invisible. Planet Fitness's brand, pricing, and member experience are set at the chain level, not by individual franchisees. What changes is the capital investment pace and the operational sophistication behind the clubs. Flynn Group has the scale to invest in equipment upgrades and amenity expansion across 98 clubs simultaneously in ways that a smaller operator could not afford to.
Where the Fitness Franchise Category Is Headed
The broader context for this deal is that the fitness franchise industry is experiencing the kind of consolidation wave that restaurants went through 15-20 years ago. Crunch Fitness was sold to Leonard Green Partners earlier in 2026 as TPG exited. Xponential Fitness is publicly considering a sale amid investor pressure from Voss Capital. The Club Pilates franchise system continues to expand rapidly. The pattern is consistent: high-quality category leaders with proven unit economics attract financial and strategic buyers, and the category concentrates into fewer, larger operators.
For Planet Fitness, the bigger question is whether the chain can sustain the same-store sales growth that has underwritten these acquisitions. The company opened 181 new clubs in 2025 and ended the year with 2,896 locations and 20.8 million members. Q4 2025 systemwide same-club sales were up 5.7%, decelerating from the full-year 2025 rate of 6.7%. TD Cowen wrote in a research note last month that while Planet Fitness is a "high-quality asset," management "needs to move faster, strengthen execution, improve the value prop given growing disruption from high-quality peers and better monetize its member base."
Flynn's answer to that concern was direct. "I see no reason not to believe in Planet Fitness," he said. DeMartinis added that his team has evaluated "probably 15 businesses" in the Planet Fitness system over the last two and a half years and that more acquisitions are "undoubtedly in the cards."
What to Watch Next
Three things will shape how this deal performs over the next 18 months. The first is whether GLP-1 adoption continues to support gym membership rather than cannibalizing it. Early data is positive, but the durability of that pattern as GLP-1 pricing changes and generic options emerge is not yet settled.
The second is the next Flynn Planet Fitness acquisition. DeMartinis's "15 businesses" comment signals that the pipeline is deep, and another 50 to 100 club acquisition over the next two years would push Flynn into the top three Planet Fitness franchisees. That changes the competitive dynamic between Flynn and the other large Planet Fitness operators, particularly those backed by private equity that may face their own exit pressures in 2027 and 2028.
The third is Planet Fitness itself. The chain's same-store sales deceleration, combined with the TD Cowen critique, suggests the brand needs to refresh its value proposition. Wellness-focused competitors are offering more amenities at similar price points, and Planet Fitness's "no-frills" identity that powered its growth through 2020 may need updating. How the brand evolves the member experience in 2026 will determine whether Flynn Group's bet looks farsighted in three years or slightly early.
