Sun Holdings: How America's No. 2 Franchisee Became a Restaurant Brand Buyer

Guillermo Perales didn't set out to become a restaurant brand owner. He set out to be the best franchisee in the country, and for the better part of three decades, he delivered on that ambition. Sun Holdings, the Dallas-based company he founded in 1997, operates roughly 1,800 restaurant locations across Arby's, Papa Johns, Burger King, Applebee's, Popeyes, IHOP, McAlister's Deli, and GoldStar Chili. That scale puts Sun Holdings at No. 2 on the Franchise Times Restaurant 200, behind only Flynn Restaurant Group.

But somewhere between the 1,000th and 1,800th unit, Perales started doing something the franchise world doesn't often see: buying the brands themselves.

Since 2019, Sun Holdings has acquired Taco Bueno, Freebirds World Burrito, Uncle Julio's, and most recently Bar Louie, a 39-unit gastropub chain that had been through bankruptcy not once but twice. Each deal follows a recognizable pattern. The brand is distressed, the price reflects that distress, and Perales believes his operational machine can do what previous owners could not.

From Operator to Owner: The Career Arc#

The trajectory makes more sense when you understand how Sun Holdings got big in the first place. Perales didn't build a 1,800-unit portfolio by being a passive check-writer. He built it by running restaurants well, at scale, in competitive markets. Sun Holdings operates across Texas, and the franchise relationships it holds span quick service, fast casual, and casual dining. Managing that diversity requires genuine systems: training pipelines, labor models, supply chain discipline, and the kind of unit economics obsession that separates durable multi-unit operators from those who overexpand and collapse.

That operational DNA is exactly what distressed restaurant brands tend to lack. The chains Sun Holdings has targeted share a common profile: recognizable concept, loyal customer base in specific regions, but years of underinvestment, ownership instability, or financial engineering that hollowed out the fundamentals. Perales is betting his team can plug into these brands the same way they plug into a new franchise system, bringing process discipline where there was chaos.

The franchise business also generates cash flow at scale. With roughly 1,800 locations producing royalties, fees, and operating income, Sun Holdings has the financial base to pursue acquisitions that would stretch a smaller operator. The two business lines feed each other.

The Acquisition Playbook#

The strategy has a clear structure. Sun Holdings targets brands in financial distress, typically at the point where the original equity is wiped out and creditors are in control. That's when prices reflect operational reality rather than brand aspiration.

Taco Bueno came first, acquired in 2019 out of bankruptcy. The Tex-Mex chain had been struggling for years under private equity ownership, carrying debt loads inconsistent with its unit economics. Perales acquired the brand at a discount to replacement cost, inheriting real estate liabilities but also a concept with genuine regional loyalty across Texas, Oklahoma, and surrounding states.

Uncle Julio's required a more creative approach. Sun Holdings acquired the company's debt in mid-2024, then purchased the brand outright via foreclosure auction in December of that year. The debt-to-equity conversion strategy is a private equity staple, but it's relatively unusual among restaurant operators. Buying at the debt level gives the acquirer control over the outcome rather than leaving it to a bankruptcy process where multiple bidders can push prices up. Sun Holdings effectively set the floor on what Uncle Julio's was worth by controlling the debt before anyone else could.

Uncle Julio's is an upscale Tex-Mex concept with about 35 locations, concentrated in Texas and the Southeast. It occupies a different segment than Sun Holdings' QSR core, which signals that Perales isn't limiting his acquisition appetite to familiar territory.

Freebirds World Burrito followed in August 2024, adding another Tex-Mex adjacent brand to the portfolio. The chain competes in the fast casual burrito category that Chipotle dominates nationally, but has a regional identity in Texas that gives it differentiated positioning.

Bar Louie represents the most recent, and perhaps most ambitious, acquisition. The gastropub chain had filed Chapter 11 bankruptcy twice, the second time in 2025. By the time Sun Holdings acquired it, the concept had been reduced to roughly 39 units from a peak above 130. Two bankruptcies in a short span is a serious warning sign in any sector. In the restaurant industry, it typically indicates structural problems with the concept, the cost model, or both. Sun Holdings acquiring Bar Louie suggests Perales believes the failures were execution-related rather than inherent to the concept itself. Whether that assessment proves correct will tell operators a great deal about the limits of franchise discipline applied to casual dining.

Why the Franchisee-to-Franchisor Model Is Getting Traction#

Sun Holdings isn't alone in making this move. Across the industry, sophisticated multi-unit operators are beginning to acquire brands rather than simply license them. The logic is straightforward. Large franchisees already have the infrastructure that small brand owners struggle to build: hiring systems, training programs, supply chain relationships, technology platforms, and real estate expertise. The marginal cost of applying that infrastructure to a new brand is lower than building it from scratch.

The M&A environment in 2026 reinforces this dynamic. A Citizens Financial survey found that 58% of middle-market executives and private equity firms expect restaurant M&A to increase this year. Distressed assets are available at prices that reflect operational failure rather than concept value. Capital markets remain selective about new restaurant concepts, making acquisition of established brands more attractive relative to greenfield development.

For franchisees specifically, brand ownership resolves a fundamental tension in the franchise relationship. Franchisees build businesses, develop operational expertise, and often generate most of the system revenue, but they don't control the brand decisions that affect their unit economics: menu changes, marketing spend, fee structures, technology mandates. Owning the brand eliminates that tension. Perales can align brand strategy with operator reality because he is simultaneously the operator.

The Risks Nobody Should Ignore#

The franchise-to-brand-owner transition carries real risks, and the Bar Louie acquisition in particular makes them concrete.

Running locations and running brands are different disciplines. A franchisee's job is execution: take the system, run it well, generate returns. A franchisor's job includes brand strategy, marketing, product development, and franchisee relations. These require different skill sets and organizational capabilities. Sun Holdings has proven excellence at the former. Its track record on the latter is still being written.

Brand strategy at casual dining scale is genuinely complex. Taco Bueno and Uncle Julio's operate in segments where Sun Holdings has deep familiarity. Bar Louie is a gastropub concept targeting an urban, millennial-leaning customer base. That's a different marketing conversation than Tex-Mex quick service, requiring different agency relationships, different digital strategy, and different menu development capabilities.

The management bandwidth question is also real. Running 1,800 locations across eight franchise brands already demands significant organizational capacity. Adding four owned brands, each requiring turnaround attention, compounds that demand. Sun Holdings has grown fast, and fast growth always tests whether culture and systems scale with headcount.

The distressed acquisition strategy itself has a built-in risk: the brands were distressed for reasons. Franchisee networks may be demoralized or depleted. Real estate portfolios may include unfavorable leases inherited from expansion eras. Supply chain contracts may be unfavorable. Each acquisition is a bet that Sun Holdings' diagnosis of the problem is correct and that its proposed remedy is sufficient.

What This Means for 2026 M&A#

The Sun Holdings trajectory is a leading indicator for where restaurant industry M&A is heading. Private equity firms that dominated restaurant brand acquisitions throughout the 2010s have a mixed track record: the aggressive use of leverage that worked in low-rate environments produced multiple bankruptcy cycles when sales growth stalled. Operators bring something different. They have direct experience running restaurants, they tend to make less aggressive capital structure assumptions, and they have existing operational infrastructure rather than needing to build or acquire it.

For distressed restaurant brands, Sun Holdings-style acquirers represent an attractive exit path for creditors. A sophisticated operator with real infrastructure and a clear operational thesis is a more credible turnaround candidate than a private equity sponsor who will need eighteen months to build the management team.

The 2026 M&A environment, with elevated distress across casual dining and legacy fast casual, should produce more targets for operators willing to make this move. The question for Sun Holdings is whether its track record through 2025 converts into a repeatable advantage or whether the complexity of managing owned brands alongside a massive franchise portfolio eventually creates its own constraints.

Perales built the No. 2 franchise operator in America by staying disciplined about what he was good at and scaling it relentlessly. The brand acquisition strategy extends that discipline into new territory. The early results, particularly with Taco Bueno's regional persistence and Uncle Julio's foothold in upscale Tex-Mex, suggest the model is viable. Bar Louie will test it at the edges.
