What is the difference between platform and add-on multiples?
Platform acquisitions trade at higher EBITDA multiples than add-ons because the buyer is paying for scale, management and a base to acquire from, while an add-on brings its earnings into a platform that already has those things. In dental, FOCUS Investment Banking puts platform investments at 9–11× EBITDA and add-on acquisitions at 5–8×.

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 EBITDA: the management team, the operating system, the brand, the payer contracts, and the option to grow through acquisition. Add-on deals trade lower because the platform already has all of that infrastructure; the add-on contributes EBITDA and incremental growth. FOCUS Investment Banking describes the split for dental: platform investments at 9–11× EBITDA are larger groups with five or more doctors, several sites, established governance and revenue cycle infrastructure, while add-on acquisitions at 5–8× are practices with one to three locations folded into a DSO. The classic playbook is to buy a platform, buy add-ons at lower multiples, and sell the combined business at a platform multiple. This is called multiple arbitrage. Worked example on those dental ranges, with hypothetical practice sizes: a platform with $3M of EBITDA bought at 10× costs $30M, and a dozen add-ons with $1M of EBITDA each bought at 5× cost $60M, so the buyer holds $15M of EBITDA for $90M, a blended 6×. Sold at 12×, the top of the 10x to 12x+ range McLerran & Associates publishes for platform-grade dental groups with $5M+ of EBITDA, that $15M is worth $180M, twice what was paid, before debt, fees or any EBITDA growth. For sellers, the takeaway is that being acquired as a platform pays more than being acquired as an add-on, but it requires scale and a management team that can run more locations. In FOCUS's dental ladder, the rung it labels "emerging platforms" is $3M to $5M of adjusted EBITDA.
Platform investments price at 9–11× EBITDA (larger groups with 5+ doctors, a multi-site footprint, established governance and revenue cycle infrastructure); add-on acquisitions price at 5–8× (practices with 1–3 locations integrated into a DSO).

What this means for clinic owners
From Sorso
If you can grow past the size where buyers treat you as an add-on, you change buyer category. In FOCUS's dental ladder, practices under $1M of adjusted EBITDA sell to small DSO tuck-ins or individual buyers at 5–7×, $1M to $3M goes to regional DSO add-ons at 7–9×, and at $3M to $5M the buyers FOCUS lists are emerging platforms, at 9–11×. Whether the growth investment pays depends on what it costs to get there, so model it before you fund it.

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 10–12× 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.
What is the average EBITDA multiple for an urgent care center?
Scope Research publishes three tiers for urgent care in its 2026 update: single centers and small portfolios (typically under $10M of revenue) at 3x to 7x EBITDA, regional multi-location operators ($10M to $50M of revenue) at 6x to 11x, and large platforms or operators with a value-based or virtual care strategy at 10x to 15x. The caveat Scope attaches to that top tier matters more than the number: the majority of the deals at the high end are from the mid 2010s.
How do PE firms value medical practices?
Private equity firms value a medical practice as a multiple of its trailing-twelve-month adjusted EBITDA, and the multiple rises with scale. Published ladders run from 2.5–4x for a single owner-operated physical therapy clinic (Breakwater M&A) to 10x–20x for large primary care platforms (Scope Research), and payer mix, growth and owner dependence move a practice within its band.
When should I add a second clinic location?
Add a second location when the first one is full, profitable on normalized numbers and able to run without you every day, and when you can pay for the build-out and the months before the new site collects cash without touching your operating reserve.
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, generally 10 to 40 percent of the practice's total enterprise value in physician deals according to Foley & Lardner, 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.
