Shareholder Buy-Out Valuation Under UK Company Law
Buying out a departing shareholder needs a defensible number. Most disputes settle at this stage, not in court.
When a shareholder leaves, the right valuation can resolve the matter in weeks. The wrong one feeds two years of litigation. Most UK SME shareholder disputes settle on the basis of an independent valuation, not in front of a judge. This guide explains how shareholder buy-outs are valued, why minority discounts matter, how the valuation date is set, and how single-joint-expert appointments work when the parties cannot agree.
Whole-equity value first
A UK shareholder buy-out is priced on the whole-equity value of the company, allocated pro rata to the disputed holding, with section 994 unfair-prejudice valuations excluding the minority discount the court ordinarily applies. That establishes the pie before any minority or marketability adjustments are made. Skipping this step is the single most common reason valuations are challenged.
Minority discounts
A minority shareholder cannot direct the business, declare dividends, or trigger a sale. That lack of control is worth a discount of typically 15 to 30%. The size of the discount reflects the rights attached to the shares: protective rights and reserved matters reduce the discount; pure passive minority status widens it.
Where a buy-out is forced by an unfair-prejudice petition under section 994, the courts may decline the minority discount in some circumstances, reflecting the principle that the minority should not be penalised for the conduct that triggered the buy-out. Each case turns on facts.
Marketability discounts
Beyond minority, unquoted shares carry a discount for lack of marketability: the holder cannot readily sell to a third party. The discount is typically 5 to 15%, larger for very small holdings or where a shareholders' agreement restricts transfers.
The valuation date
The valuation date matters enormously. Disputes often turn on whether the date is the date of the triggering event (a dismissal, a death, a notice to leave), the date of the proceedings, or the date of the order. Different dates can produce values 30% apart in fast-moving businesses. The valuer must state the date used and the rationale.
Single joint expert appointments
Where the parties cannot agree on a valuer, the court may appoint a single joint expert under CPR Part 35. The SJE reports to both parties simultaneously, owes their duty to the court, and produces a report that is generally binding subject to limited challenge. We are regularly appointed as SJE for unfair-prejudice petitions, section 994 buy-outs, and shareholder agreement disputes.
Pre-litigation valuation as a settlement tool
Often the most valuable use of a valuation is pre-litigation. A clear, independent report frequently settles disputes that would otherwise spend two years in court. The cost of a £4,000 valuation report against £100,000 of legal fees and twelve months of distraction is a compelling case for early independent input.
Key takeaways
- Start from whole-equity value, then apply minority and marketability discounts.
- Minority discount is 15 to 30%; marketability is 5 to 15%.
- Valuation date materially affects the number; pick it carefully.
- Pre-litigation valuation often settles disputes without court.

Share & Shareholder ValuationFrequently asked questions
What discount applies to a minority shareholding?
Typically 15 to 30% for lack of control, plus 5 to 15% for lack of marketability. Total discount of 20 to 45% versus the pro-rata value of the whole-equity figure.
When does the minority discount not apply?
In some forced buy-outs under section 994 the court has held it inequitable to apply a minority discount where the buy-out is triggered by majority conduct. The principle is fact-specific.
What is the right valuation date?
Most commonly the date of the triggering event (notice to leave, death, or dismissal). The court may set a different date if equity requires. The valuer must state the date used.
Can we use one valuer for both sides?
Yes, as a single joint expert. The SJE reports to both parties and the court, with strict independence requirements under CPR Part 35.
How much does a shareholder buy-out valuation cost?
Typically £3,500 to £7,500 plus VAT depending on complexity and whether oral evidence is likely. Quoted in writing before instruction.
Can a valuation report settle a dispute before court?
Often yes. A clear independent report frequently moves both sides off entrenched positions and settles matters that would otherwise cost six-figure legal fees.
