Key Person Risk in valuation and sale: What must a keyman coach know about the key person discount?
In a sale, Key Person Risk becomes a price. Buyers and valuers ask how much of the business would remain if the key person were gone.

Key Person Risk in valuation: How large can the discount be?
Where core functions, relationships and strategic decisions are closely linked to the owner, buyers and investors become cautious; according to the valuation provider Quantive, valuers apply discounts of 20 to 40 per cent where owner dependence is high.
Key Person Risk in research: What does the loss of a CEO cost?
Bennedsen, Pérez-González and Wolfenzon (2020) show, measured through hospital stays, that the absence of the CEO affects profitability and investment. In a sample of 449 CEO deaths in listed US companies, sudden deaths go with a share price reaction of −1.72 per cent on the announcement day, more strongly where the CEO is hard to replace (Jenter et al., 2023).
Key Person Risk before a sale: Why does reducing dependence take time?

Key Person Risk in valuation: Which questions should be settled before a sale?
- How much revenue comes from customers who speak only to the owner?
- Which decisions does the second management level make on its own today?
- Which knowledge exists only in one head?
- How would the business run during a three-month absence of the owner?
Key Person Risk in valuation: Where is the gap that the valuation leaves open?
