Antitrust has arrived in outpatient consolidation, and dental is next

There's signs that antitrust enforcement has arrived in outpatient consolidation and not just hospital mergers.

For a decade the regulatory lens has mainly sat on hospitals. Surgery centers, the classic outpatient roll-up, were assumed to be too fragmented and too small to draw antitrust attention. But that assumption is dying, and in a vertical that structurally looks exactly like dental. Hundreds of small sites rolled up fast, by financial buyers, into platforms that are getting large enough to be visible.

Dental is the most consolidated yet least scrutinized outpatient vertical there is. There's more than a 100 PE-backed DSO platforms, thousands of practices absorbed, and some states already moving on corporate ownership of dental practices. We're reaching a point where it matters whether the platforms being built right now are built to survive it.

When that scrutiny arrives, it doesn't just test the legal structure. Regulators, lenders, and the next buyer all end up asking the same underlying question in different words: is the platform actually as good as its financials say?

And the place that question gets safely answered is not the cap table or the MSO agreement, but inside each practice, per location, in the operational numbers nobody really properly documented while the multiple was doing all the work.

That is where the gap lives in my opinion. Financial QoE tells a buyer what each practice collected, not what each practice was capable of collecting and didn't, or whether the trailing EBITDA being underwritten is durable or quietly propped up by a recall system that was already breaking. When a platform reaches recap and a sophisticated buyer finally opens the practice management system, the deals that stall are the ones where the operational reality never matched the financial story. Diligence purgatory is just the polite name for a platform that was never built to be examined at the location level.

The next recapitalisation will not reward whoever acquired the most, but the platforms that can be opened up and examined without the story falling apart.
