What Is Key Person Risk in a Portfolio Company?
Private equity firms and institutional investors do not buy businesses that cannot survive without their founders. They buy transferable cash flows. Key person risk threatens that transferability.
How Key Person Risk Shows Up
- Revenue concentration: The founder personally manages the top clients. If they leave, clients follow.
- Decision dependency: Every major decision requires the founder's approval. The management team has no real authority.
- Knowledge concentration: Critical pricing, vendor, and strategic knowledge exists only in the founder's head.
- No tested successor: There is no one who has been given real responsibility and proven capable of stepping in.
How Investors Respond
When investors identify key person risk, they typically take one of three actions. They may discount the valuation to reflect the cost of replacing the key person or the risk of client loss. They may require the founder to stay post-acquisition through an earn-out, often 2 to 3 years, with significant financial penalties for early departure. Or, if the risk is too high, they may walk away entirely, even if the financials are strong.
The highest multiple transactions go to businesses that have eliminated key person risk. The lowest go to those that have not.
