Partial Sale Valuation for UK SME Owners Selling a Stake

Overview

A partial sale is the sale of between 25% and 70% of the equity in a private UK company to a financial or strategic investor, with the founder remaining in an active role and retaining the balance of the shares. The owner takes meaningful cash off the table today, keeps operational control and preserves a material economic interest in the next stage of growth. The whole question turns on one thing: an independent valuation, prepared before any investor is approached, that anchors price, percentage and protections in evidence rather than enthusiasm.

The whole-company enterprise value is calculated first using the same methodology as a full sale, normalised EBITDA against private-company transaction multiples in the relevant sub-sector. The minority consideration is then a pro-rata share of that value, less a Discount for Lack of Control of typically 10% to 25% and, where relevant, a smaller Discount for Lack of Marketability. Strong governance rights, a defined exit path and pre-emption protections compress both discounts materially.

The most powerful economic feature is the second bite. The proceeds from the eventual full exit of the remaining stake, typically three to seven years later, often exceed the first bite in absolute pounds because the new investor brings capital, expertise and exit experience that grows the underlying value. The valuation report models both bites side by side so the founder chooses on data, not on instinct.

End-to-end deal execution, including investor identification, information memorandum and negotiation, is handled by the specialist partner practice linked above.
