Key Person Risk

Key person risk (also called key person dependency) describes the degree to which a business's revenue, customer relationships, supplier access, or operational knowledge is concentrated in one or a small number of individuals — most commonly the founder or owner. When critical business functions depend on a single person who will not be staying post-sale, the business carries elevated risk that buyers price into their offer.

Key person dependency is one of the most common reasons buyers discount their offer or require extended transition arrangements. Its manifestations include: customers who buy because of their relationship with the owner personally (rather than with the business brand or team); proprietary knowledge or technical skills held exclusively by the owner; supplier or referral relationships maintained solely through the owner's personal network; and sales processes that depend on the owner's direct involvement to close. The more deeply embedded the key person dependency, the shorter the effective runway a buyer has to stabilize the business before value erodes.

Buyers typically address key person risk in two ways: through price (a lower multiple to reflect the higher risk) or through structure (requiring a longer transition or earn-out period during which the seller remains involved and value transfer can be demonstrated). Sellers who have built systems, documented processes, trained a management team, and diversified customer relationships — reducing their personal indispensability — will consistently achieve better terms than those who have not. Beginning this work two to three years before an anticipated sale is advisable.
