What is the difference between platform and add-on multiples?
Platform acquisitions trade at 8x to 14x EBITDA — the buyer pays for scale, infrastructure, and management. Add-on acquisitions trade at 4x to 7x EBITDA because they bolt onto an existing platform. The same practice can be worth 2× more depending on which the buyer needs.

Definition
A platform acquisition is the first investment in a new vertical for a PE firm; an add-on is a smaller follow-on acquisition tucked into the existing platform.
The detail
Platform deals trade at higher multiples because the buyer is paying for more than just EBITDA. They pay for the management team, the operating system, the brand, the payer contracts, and the optionality to grow through acquisition. Add-on deals trade lower because the platform already has all of that infrastructure; the add-on contributes only EBITDA and incremental growth. The classic playbook is buy a platform at 10x, then buy a dozen add-ons at 5x, blend the multiple down to 6x, then sell the combined entity at 12x to the next PE firm. This is called multiple arbitrage and it is how dental, dermatology, vet, and ophthalmology platforms have generated 3x to 5x returns for first-cycle PE investors. For sellers, the takeaway is that being acquired as a platform pays much more than being acquired as an add-on, but it requires scale (typically $3M+ EBITDA) and a management team that can run more locations.

What this means for clinic owners
From Sorso
If you can grow to $3M+ EBITDA before selling, you change buyer category. The same EBITDA dollar is worth two to three times more as a platform than as an add-on. That growth investment is almost always worth funding.

What is the average EBITDA multiple for dental practices?
FOCUS Investment Banking publishes a ladder by adjusted EBITDA with the buyer type named on each rung: under $1M at 5–7×, $1M to $3M at 7–9×, $3M to $5M at 9–11×, and $5M+ at 11×+ in select cases. McLerran & Associates puts platform-grade groups above $5M in adjusted EBITDA at 10x to 12x or more and leaves its lower tiers unnumbered. Neither firm publishes an absolute multiple for orthodontics, oral surgery or pediatric dentistry; McLerran says only that specialty practices run roughly 1 to 3 additional turns of EBITDA above general dentistry at the same size tier. Scale, not clinical quality, is what moves you up the ladder.
What is the average EBITDA multiple for PT clinics?
Breakwater M&A publishes physical therapy (physiotherapy) multiples by adjusted EBITDA: $150K to $500K at 2.5–4x for a single owner-operated location, $500K to $1M at 4–6x once a professional manager is in place, $1M to $3M at 5–7x for a platform practice with a regional footprint, and $3M+ at 6–8x+ for a roll-up target. It sums the whole market up as "2.5x to 8x EBITDA" in 2026. Peak Business Valuation states 3.0x to 6.0x with no size breakdown behind it, so read that as a cross-check on the middle of Breakwater's ladder rather than a band for any one clinic size.
How do PE firms value medical practices?
Private equity firms value medical practices primarily on a multiple of trailing twelve-month adjusted EBITDA, typically 5x to 12x, with the multiple driven by scale, growth, payer mix, and provider retention.
When should I add a second clinic location?
You should add a second location when your first location is at 80 percent or more capacity utilization, has 25 percent or higher EBITDA margins, and you have 6 to 12 months of operating cash plus dedicated growth capital.
What is rollover equity in a practice sale?
Rollover equity is the portion of sale proceeds that the selling owner retains as equity in the buyer's platform, often a meaningful share of total consideration, creating a second liquidity event when the platform is later sold.
What is a platform investment thesis in healthcare PE?
A platform investment thesis is the PE firm's plan for how a first acquired practice will grow into a multi-location roll-up through add-on acquisitions, built around growing EBITDA substantially over a hold period that now runs to a 6.0-year median. We have not found a published figure for how much EBITDA growth platforms target, so treat any specific multiple of growth as a negotiating claim rather than a benchmark.
