Black Box Intelligence published data in early March showing that 9% of all full-service restaurant locations in the United States have lost 30% or more of their peak annual sales since 2019. Their analysis classifies these units as at risk for closure in 2026, with 3% having lost more than half their peak volume. The question for buyers and sellers in SoCal is not whether the number is alarming. It is whether your specific deal sits inside or outside that 9%.

What the Data Actually Measures

The 9% figure comes from comparing each restaurant location’s current sales performance against its best year since 2019. Units that have declined 30% or more from that peak are classified as at risk because, as Black Box VP of Insights Victor Fernandez put it, “in an environment where cumulative inflation has driven costs up by nearly a third since 2019, it is virtually impossible for a unit to remain viable after losing 30% or more of its peak sales.”

The math is straightforward because the pressure works from both sides. If your costs are up 30% and your revenue is down 30%, you are operating at roughly half the margin you had at peak. For most full-service restaurants running on already thin margins, that is not survivable long-term.

The limited-service segment looks healthier by comparison, with only 4% of quick-service and fast-casual locations meeting the same at-risk threshold. Fernandez’s read on that gap is that full-service restaurants carry higher fixed costs, are more sensitive to traffic declines, and have less flexibility to adjust labor in real time.

The Segment Divergence Is Accelerating

The net unit growth numbers since 2022 tell a stark story about where capital is flowing and where it is retreating. Casual dining has contracted 3.3% in net units, fast casual has grown 15.5%, and quick-service sits in between at 5.8% growth. Technomic data adds another layer, showing independent full-service restaurants declined 2.6% in 2025 alone, with a net loss of more than 9,500 independent locations nationwide.

The chains driving the fast-casual expansion are visible in every major market. Chipotle opened its 4,000th unit and plans 315 to 345 new locations per year, Wingstop added 493 net units in a single year and is targeting 10,000 total, Cava reached 439 locations with 74 to 76 new openings projected for 2026, and Raising Cane’s is adding more than 100 units annually with no sign of slowing down.

On the other side, the closures are just as visible. Red Lobster shuttered roughly 130 locations through bankruptcy, TGI Fridays is down to approximately 85 U.S. locations, and Denny’s closed around 150 underperforming units. Noodles & Company more than doubled its planned closures to 30-35 restaurants in 2026, shrinking its footprint by over 18% in two years.

Where the At-Risk Units Are Concentrated

Black Box identified geographic hot spots with the highest concentration of units performing at or below 70% of their peak sales. The list includes Fresno-Visalia in California, Oklahoma City, Tulsa, Harlingen in Texas, Little Rock, Louisville, Chattanooga, Macon, and the Mobile-Pensacola corridor.

No Southern California market appears on the geographic at-risk list. That might seem reassuring until you look at the local data separately. The California Restaurant Association reported that 72% of restaurants in San Diego County experienced declining customer traffic through 2024 and 2025. SanDiegoVille documented more than 70 bar and restaurant closures in the county in 2025. Profit margins for San Diego operators have compressed to 3-5%, down from the 8-10% range that was standard before COVID. Outdoor dining fees on city streeteries have climbed to $30 per square foot, which for some operators costs more than their indoor lease.

San Diego is not on the Black Box at-risk list, and the closure wave here is still this severe. That tells you something about how deep the stress runs in markets that did make the list.

What This Means if You Are Selling

The 42% of operators who reported unprofitable operations in 2025, according to the National Restaurant Association’s annual report, are not all going to list their businesses for sale, and many will simply close. But among those who do come to market, the data creates a clear pressure point. Buyers have leverage they have not had in years, and sellers who wait too long risk listing into a market with rising inventory and declining multiples.

The NRA projects $1.55 trillion in restaurant and foodservice sales for 2026, a 4.8% nominal increase that translates to just 1.3% real growth after inflation. Revenue is growing on paper while profitability erodes underneath, and a buyer evaluating your financials will see right through top-line growth if the margin story does not hold up.

The strongest position for a seller right now is demonstrable traffic stability. If your location is holding or growing customer counts while the surrounding market contracts, that resilience commands a premium. If your traffic is declining and you are compensating with price increases, a buyer will discount accordingly because that strategy has a ceiling.

What This Means if You Are Buying

Fernandez framed the opportunity in a way worth quoting at length. “A leaner portfolio often becomes a stronger one. When a brand stops subsidizing its bottom 10% of units, it can reallocate capital, management attention, and marketing spend to the units with the highest growth potential.” That logic applies at the individual-deal level too. The restaurants exiting the market are creating second-generation spaces with existing kitchen infrastructure, permits, and sometimes transferable liquor licenses at valuations below what they would have commanded two years ago.

The 9% at-risk figure is a national average, and national averages obscure the opportunity. In SoCal, the combination of high lease costs forcing closures and strong underlying consumer demand means the delta between a failing restaurant and a well-positioned one in the same trade area can be enormous. The buyer who understands which side of that delta a deal sits on is the one who builds real value.

A YouGov survey from early 2026 found that 53% of consumers set a dining budget this year, up from 46% in 2025, and two-thirds of those expecting financial pressure plan to reduce restaurant spending. That is the demand environment any acquisition will operate in for the foreseeable future, and every underwriting model should reflect it.
