I do have a very good source on the number above and also the offer price and estimate. So I will refrain from arguing over what is "possible" from each one of your perspectives. But the bottom line is whether the PE sale price is 5M or 10M or somewhere in between, it is still a lot more than the 1.5M that would have been made sold to a new BCD. Also, there are not that many BCD on the market to buy existing practices. To even be a qualified buyer, someone has to go to met school, get into a derm residency, and graduate to decide to buy a practice. Last time I checked it was less than 20% of new graduates. Then the said person has to be willing to move to a highly underserved area with no opera house in the city. Finally, you have to convince the person that it is better to buy the practice from you then to set up shop next door. The candidate also needs to have the means to finance the purchase price. Even if you want to sell for 1.5M, you won't find a buyer to do so. For any derm who build a profitable infrastructure a secondary market, selling to PE seems to be the only option.
Granted, you will be funding your own buyout. It will make no sense if you are young. But for a retiring derm, it makes perfect sense because you won't deal with the risks of patient abandonment for closing the practice, but rather it will transition to the new PE ownership.
To MOHS_01's point, salaries of PA capping at 20% still leaves 800K to the EBITDA if the PA generate 1M a year. It is not an impossible task with the right patient population with lots of freezing and biopsies. Throw Mohs surgery in the mix the number is not unreasonable. As the market rate of the replacement derm at this particular setup, I suspect one derm replacement at 40% still generates plenty of EBITA given the cost of supervision of the existing PA infrastructure. Heck, a derm may not even need to be replaced but rather supervised by existing PE employee derm in another city within the same state! The PE simply manage the existing infrastructure and fly in Mohs once a month to do the cases.
To Reno911, No one is owning their clinic building. I only discussed to illustrate the difference between EBITA and EBITDA. I reiterate that whether the sale is 2X, 5X, or 10X of EBITA, there is no BCD buyer for the practice. If your goal is to retire, no matter how many years you want to drag the practice on, it will need to end sometime. Rather than shut the practice down, you might as well get paid for the infrastructure. Just because you are already incredibly wealthy from have accumulated wealth doesn't mean should not sell your practice for a good price when you want to get out of the game.
