I'm looking at a commercial cleaning business that does about 1.5MM EBITDA with 80% coming from multiple contracts all under the umbrella of a single university hospital. Most advice tells me to factor this into the asking price, instead of trying to tie seller compensation to it because the seller won't have any control over my performance in the business after they leave. Any advice on how to factor this into the multiple, or another way to mitigate this risk?
