What's the deal with all of the car washes?

Today, I'm digging into Mister Car Wash (MCW).

If the area where you live is anything like the area where I live, these car washes are popping up all over the place.

Historically, density has provided a moat for a business like this, as competitors want some headroom when they're coming into new locations. But the frothiness of 2021-2022 spilled over into the car wash space and led to wild growth.

Today, I'm going to do a little financial analysis. I want to try to better understand the per-location economics for their car washes.

Let's first try to estimate their per-store gross margin in 2024.

• From 2023 to the end of 2024, they grew their store count from 476 locations to 514. Quarterly store growth was relatively even, so we can split the difference and estimate a weighted average 495 stores in 2024.

• They had $299 million of gross profit in 2024.

• $299 million/495 = $604k gross profit per location

Now let's try to estimate what each one of the locations cost to build.

• Some quick industry research tells me that for a business like this, 70% of capex would go towards new builds and 30% towards maintenance capex.

• They had $330 million of CapEx in 2024, so 70% of that is $231 million

• I'm making an assumption that they had ~30–35 equivalent “new-builds” after adjusting for acquisitions vs ground-up

• $231 million ÷ ~30–35 ≈ $6.6M to $7.7M per location

That gives us an approximate 9% gross profit per location if my math is correct. Not bad!

But I forgot one big thing!

We need to factor in overhead. Using the same logic as before, their SG&A was approximately $500k per store.

That leaves a net profit of only $100k per store. Ouch.

Given what we've talked about in prior reports, operating leverage is key. Most of the corporate overhead here doesn't increase linearly along with the revenue from new car washes.

So, this likely explains a lot of the aggressive growth we've seen in the car wash industry.

They have found an opportunity with:

1. A business model that the customers seem to like, with the repeatability that is attractive.

2. Processes for building and operating car washes like this are quite repeatable.

But the way to get operating leverage is you have to build more car washes.

When you have multiple companies pursuing a similar strategy, you see a proliferation of car washes like I'm seeing in my area.

All in all, the lack of true competitive moat in this business leaves me bearish on the industry. The thing that would change that is if a couple of the weaker players fail, and there's a roll-up opportunity amongst one of the more successful car wash operators.

With that, let's work on businesses that have more opportunities for competitive moats!

I'll see you tomorrow.

TL;DR

• Mister Car Wash is the largest car wash operator in the US, with more than 500 locations and a business model built around high-frequency usage and subscriptions.

• The Unlimited Wash Club (UWC) drives the economics, accounting for 74% of wash sales in FY-2024 and turning a commodity service into recurring revenue.

• The company pairs operational discipline with heavy CapEx investment to build local density and habit-driven demand.

• For entrepreneurs, the playbook shows how subscriptions, process standardization, and footprint scale can work in a physical business.

• The risk is clear: this is an asset-heavy, leveraged model where margin pressure and execution mistakes get expensive fast.

The 30,000-Foot View

Mister Car Wash operates express exterior and interior-clean car wash locations across the US. As of year-end 2024, the company ran 514 locations in 21 states, with the majority focused on high-throughput express exterior washes. The business is designed around speed, consistency, and convenience, with heavy emphasis on repeat usage.

The core of the model is the Unlimited Wash Club, a monthly subscription that allows customers to wash their vehicles as often as they want at any Mister location. Revenue from subscriptions is recognized ratably, smoothing cash flows and improving predictability. One-off retail washes still matter, but they increasingly function as an acquisition funnel for subscriptions.
