Latest / The Buyout Show with Fexingo: Private Equity, Roll-Ups, and Business Acquisitions / The Car Wash Roll-Up That Cost PEs Billions
Transcript
- Lucas: So, you've seen the car wash on the corner with the glowing sign, the vacuums out front, the monthly subscription wash pass. It looks like a simple, boring business. And for a while, private equity thought it was the perfect roll-up. Luna: I remember seeing deals for car wash chains everywhere around 2021. Mister Car Wash, I think, was the biggest. Lucas: Exactly. Mister Car Wash was the poster child. They went public in June 2021 at $16 a share, which valued the company at about $5 billion. And the pitch was beautiful: car washes are recession-proof, right? People always need clean cars. Plus, they had this membership model — unlimited washes for $20 a month — which gave them recurring revenue. It was the subscription economy applied to a dirty car. Luna: And they rolled up hundreds of locations. I think they had over 400 by the time they went public. Lucas: Yeah, they were the largest operator in the U.S. But the roll-up is the story. From 2015 to 2021, they acquired over 200 car washes, often paying 10 to 12 times EBITDA. And they financed those acquisitions with cheap debt — floating-rate loans tied to LIBOR or SOFR. When rates were near zero, that math worked perfectly. Luna: So what broke? Lucas: The Fed started hiking in March 2022. Within 18 months, the federal funds rate went from near zero to over 5 percent. The interest expense on Mister Car Wash's variable-rate debt — about $1.5 billion of it — went from roughly 3 percent to over 8 percent. That's an extra $75 million a year in interest costs. Luna: And their EBITDA at the time was around $250 million. So interest coverage went from comfortable to dangerous. Lucas: Right. By late 2023, their interest coverage ratio — EBITDA divided by interest expense — had fallen below 1.5 times. Some analysts estimated it dipped to 1.2 times. That's close to a covenant breach. And the stock? By October 2023, it was trading around $6, down 63 percent from its IPO price. Luna: Wait, but the underlying business — the actual car washing — was still stable, wasn't it? Were memberships falling? Lucas: Not really. Revenue actually grew a bit, and membership retention held around 75 percent. The problem wasn't the operations. It was the balance sheet. The roll-up had loaded the company with debt. And when interest rates spiked, the fixed charges became crushing. The business's cash flow couldn't cover them. They had to negotiate a covenant waiver with lenders in early 2024. Luna: So the operating model was fine, but the financial engineering broke it. That's the classic PE risk. Lucas: Exactly. And what makes this a cautionary tale is that the roll-up logic assumed cheap debt forever. The sponsors — Leonard Green & Partners and other firms — had an exit. They sold shares in the IPO. But the public market investors got left holding the bag. The goodwill on the balance sheet? Over $1.2 billion. That's mostly intangibles from the roll-up — the premiums paid above tangible assets. If they have to impair that, it's a write-off. Luna: I want to step back. Why were car washes such a popular roll-up target in the first place? Lucas: Three reasons. One, fragmented market — most car washes are mom and pop. Two, recurring revenue via memberships — smooths out seasonal demand. Three, real estate: each location has land, and historically, land values appreciate. PE firms thought they were buying a combination of a cash-flow machine and a real estate play. Luna: But the real estate didn't help when the debt cost more than the cash flow. Lucas: No. And that's the thing. The real estate thesis works if you don't lever it too much. But Mister Car Wash had debt at 5.5 times EBITDA. When your cost of debt triples, you're underwater even if the property values hold. The interest eats all the cash. Luna: Are there other car wash roll-ups that went similarly wrong? Lucas: Yeah, smaller ones. Take a company like Zips Car Wash, which was backed by private equity. They also did a roll-up, going from a handful of locations to over 200. They filed for Chapter 11 bankruptcy in early 2024. Same story: too much debt, not enough flexibility when rates rose. The whole sector — publicly traded and private — got hammered. Luna: So who got hurt most? The lenders or the equity holders? Lucas: Equity holders took the first hit. Public shareholders in Mister Car Wash lost about $2 billion in market cap. The PE firms? They sold some stock in the IPO, so they recovered their cost plus some profit. But the debt holders had to take covenant relief and accept lower spreads. They didn't lose principal, but they didn't get the high returns they expected either. The real pain was for retail investors who bought the stock at $16. Luna: I remember the IPO prospectus talked about 'recession-resistant' revenue. But recession-resistant doesn't mean interest rate resistant. Lucas: Exactly. And that's a lesson for anyone looking at roll-ups. The model works in a low-rate environment. But when the cost of capital changes, the whole structure can crack. The underlying business might be stable, but the debt is a fixed cost that can blow up. In 2024, Mister Car Wash's free cash flow after interest was basically zero. They couldn't invest in new equipment or expansion. Luna: What's the state of the company now? Mid-2026? Lucas: They've been de-levering slowly. They used cash flow to pay down some debt, but they're still at about 4.5 times leverage. The stock has recovered a bit — it's around $9 now — but it's nowhere near the IPO price. The roll-up era in car washes is over. No one's doing big acquisitions in the space right now. The cost of debt is too high, and valuations haven't adjusted enough. Luna: But there are still small operators doing well, right? The ones that didn't take on much debt. Lucas: Absolutely. The mom and pop car washes with a single location and no debt? They're fine. They just have a higher cost for their variable-rate loans, but they're not drowning. The lesson isn't that car washes are bad businesses. It's that leverage amplifies risk. And when you buy at 10 times EBITDA with borrowed money, you're betting that the world stays favorable. It didn't. Luna: I want to bring it back to the broader roll-up playbook. What should investors or operators look for to avoid this? Lucas: First, don't assume low rates forever. Model what happens if rates double. Second, look at the debt structure — is it fixed or floating? Mister Car Wash used mostly floating-rate debt, which was a bet that rates would stay low. Third, consider the goodwill. If you're paying a huge premium over tangible assets, that goodwill can become a sinkhole if the business stumbles. Fourth, ensure the business has pricing power. Car washes can raise membership fees, but only so much. And fifth, have a plan for covenant headroom. Luna: So you're saying the roll-up concept isn't dead, but the conditions have to be right. Lucas: Correct. Roll-ups can create value if done with discipline. But the era of easy money allowed sloppy dealmaking. The car wash bust is a reminder that fundamentals still matter. A good business with a bad capital structure is a bad investment. Luna: It's almost ironic — the very thing that made car washes attractive for roll-ups, the stable cash flow, was the thing that lured people into taking on too much debt. Lucas: Yeah. And I think we'll see more of these cautionary tales as the lag effects of rate hikes continue to hit companies that refinance. The car wash story is just one chapter. We could talk about the same dynamic in dental roll-ups, veterinary clinics, even some SaaS roll-ups. Luna: Let's leave listeners with one concrete number to watch. What's the key metric? Lucas: Interest coverage ratio. If a roll-up company has an interest coverage below 1.5 times, that's a red flag. Below 1.0 times? They're not covering interest with operating profit. That's where you get covenant violations, distressed exchanges, or bankruptcy. Luna: Mister Car Wash flirted with that line. Lucas: It did. And it survived, but barely. The next time you see a shiny car wash with a 'Join Unlimited' sign, remember that the real action wasn't in the wash bay. It was in the debt markets. Luna: Thanks, Lucas. That was a great deep dive. Lucas: Thanks, Luna. On the next Buyout Show, we're going to look at how private equity tried to roll up the veterinary industry — and why that one might have a happier ending.
