What decision this helps you make: Whether a business would survive its key people walking out — and how transferable what they hold really is.

What this topic is

Key-person risk is the risk that a business's value rests on specific individuals — the owner, a star salesperson, a lead engineer — who personally hold the relationships, knowledge, reputation, or execution that produce the cash flow, rather than the business itself.

Why it matters

A buyer is purchasing future cash flow that depends on those people staying — and a sale can trigger their departure. So key-person risk directly reduces value and raises risk, and is a leading reason owner- and expertise-dependent businesses trade at lower multiples.

Who should learn it

Anyone buying a business, or an owner de-risking one before selling.

What you will understand

  • Understand key-person risk: value resting on specific individuals
  • See how a sale can trigger key people to leave
  • Assess what they hold and how transferable it is
  • Know the mitigations: retention, non-competes, transition, earnouts

Prerequisites

Common misconception

"The business is very profitable, so it's a strong, valuable business." If that profit depends on specific people — the owner, a star salesperson, a lead engineer — who personally hold the customer relationships, the know-how, or the execution, then the value can walk out the door when they leave (and a sale can trigger it). A business that is a few key people is worth far less, and is far riskier, than one that runs on systems. Ask: would it survive if they left?
