Key man risk (also called key person risk) is the degree to which a business's revenue, relationships, and operational capability depend on one individual — typically the current owner or a critical senior employee. It is one of the most important risk factors assessed during due diligence and one of the primary drivers of earnings multiple compression. A business where the owner holds all key customer relationships, all technical expertise, and all supplier goodwill presents a very different acquisition risk than a business with a management team, documented processes, and diversified customer relationships. Key man risk manifests in several ways: customers may follow the departing owner, staff may leave without the owner's leadership, and institutional knowledge may walk out the door. Buyers evaluate key man risk during operational due diligence by conducting customer reference calls, reviewing customer longevity and concentration data, interviewing key staff, and assessing process documentation depth. Mitigation strategies include a longer transition period, earnout provisions tied to customer retention, a consulting agreement, non-solicitation covenants, and in some cases, key person life and disability insurance on the seller during the transition.
A buyer evaluates a Port Coquitlam electrical contracting company. The owner knows every customer personally and performs most estimates himself. The two field crews respect only him. Due diligence confirms 70% of revenue comes from three builder relationships personal to the owner. The buyer prices the key man risk into a 2.8× multiple (vs market 3.5×) and insists on an 18-month consulting agreement and an earnout tied to customer retention.
