DSOs Are Rolling Up DSOs. The Economics Are Ugly.

DSOs are rolling up smaller DSOs. The economics are uglier than you think. This is not consolidation. This is margin compression disguised as scale.

What's really happening: Large DSOs (Heartland, Aspen, Smile Brands) are acquiring smaller regional players. The goal isn't clinical excellence. It's reducing corporate overhead per location. Take a 5-practice DSO with $2M in central costs. Roll it into a 200-practice DSO. Suddenly that overhead drops from $400K per practice to $40K per practice. That's the math.

But here's the catch: The acquired practice doesn't see that savings. Instead, they see new compliance, new systems, new staff who don't know their patients. Plus increased standardization. You lose the ability to hire local, price local, market local. Reimbursement doesn't change. Costs do.

Why you should care: If you're a single practice, a DSO rollup looks like liquidity and reduced stress. It isn't. You're trading autonomy for a 2-3 percent efficiency gain that you won't see. The real winner is the DSO's PE partner, who now reports better margins to their fund.

OPERATOR MATH

You own a single practice doing $2M annually. A regional DSO (25 locations) offers to acquire you. Their pitch: "We'll give you $1.4M cash + $600K earnout. You stay on as clinical director at $250K/year. We handle all admin."

Your current economics:
Revenue: $2M
COGS (lab, supplies): $400K (20%)
Staff: $700K (35%)
Overhead (rent, utilities, admin): $300K (15%)
Owner comp: $600K (30%)
EBITDA: $600K. Your take-home: $600K.

Post-acquisition economics (Year 2):
Revenue: $2M (unchanged)
DSO "management fee": 8% = $160K
DSO-mandated supply contracts (higher cost): +$40K
New compliance/software: +$30K
Your comp: $250K base + 10% production incentive = $250K + $150K = $400K
Total DSO profit from your location: $2M - $400K COGS - $700K staff - $300K overhead - $400K your comp - $160K mgmt fee = $40K.

Meanwhile, the DSO paid you $1.4M cash + $600K earnout. Financed at 6% over 7 years, their debt service: $340K/year. They're losing $300K/year on your practice for the first 3 years.

But here's the trick: they're not valuing your practice alone. They're valuing the portfolio optimization. Your practice + 4 others in the market = $10M combined revenue. Consolidated admin, centralized lab, single lease negotiation. Their real play: reduce overhead per location by $75K across 5 practices = $375K annual savings. That funds your acquisition debt.

You see $400K/year instead of $600K. They see $375K in portfolio synergies. You lost $200K/year. They gained a fund performance metric.

THE TAKEAWAY

If approached by a DSO, demand to see the post-acquisition P&L model for your specific practice. What are the management fees? What are the new cost structures? What's your real take-home after their systems are in place?

Compare your current owner earnings to the proposed comp package over 5 years. Factor in the earnout risk (most earnouts don't pay full value). If you're taking a $200K/year cut, that's $1M over 5 years - more than the upfront cash.

Ask how many practices in your market they're acquiring. If you're one of several, you're a margin optimization play, not a liquidity event. They're building density, not buying your practice for its standalone value.

Run the numbers with your accountant before signing. Model: current take-home, proposed take-home, earnout risk, non-compete restrictions, and what happens if you want out in Year 3. Most sellers regret it by Year 2.
