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.
