Share Buyback Between Partners: How to Determine the Value of a Business?

A partner is leaving the business, wants to sell their shares, or needs to be bought out? Before negotiating the price, it is essential to establish a clear, documented, and defensible value of the business.

Is your share buyback ready to be valued?

Why is a valuation necessary before buying back a partner's shares?

When a partner leaves a business or shares need to change hands, both parties need a clear, documented value. Without a professional valuation, disagreements over price can escalate into costly disputes. A valuation establishes the fair market value, supports the work of lawyers and tax advisors, provides a defensible basis for negotiation, and documents the transaction. Whether the buyback is voluntary, triggered by a shareholders' agreement, or the result of a conflict, the valuation is the essential starting point.

Why Get the Shares Valued Before a Buyback?

A business valuation before a share buyback between partners serves several critical purposes:

  • Establish a documented and defensible fair market value
  • Reduce disagreements between partners on the price
  • Support the work of lawyers, tax advisors, and accountants
  • Structure the transaction with credible financial data
  • Provide a basis for negotiation that both parties can reference
  • Document the value for tax filing and potential audits

Without a professional valuation, each partner may have a very different idea of what the business is worth. This creates friction, delays, and can ultimately prevent the transaction from closing.

Common Situations Requiring a Valuation

A share valuation between partners is typically needed in the following situations:

Voluntary departure of a partner

A partner decides to leave the business and sell their shares to the remaining shareholders.

Disagreement between partners

Partners cannot agree on the direction of the business or the value of their respective shares.

Buyback of a minority shareholder

Majority shareholders need to buy out a minority partner at a fair price.

Death, disability, or incapacity

A triggering event in the shareholders' agreement requires a buyback at fair market value.

Shareholder reorganization

The ownership structure needs to change for strategic, tax, or operational reasons.

Clause triggered in the shareholders' agreement

A shotgun clause, right of first refusal, or mandatory buyback provision is activated.

The Role of the Shareholders' Agreement

Before any share transaction between partners, it is essential to review the shareholders' agreement. This document may specify:

  • A specific valuation method to be used
  • A formula for calculating the share price
  • A fixed value or book value reference
  • A shotgun clause (buy-sell provision)
  • A right of first refusal
  • A mandatory buyback obligation upon certain events
  • A definition of fair market value or fair value

Even when the agreement specifies a method, a professional valuation is often needed to apply that method correctly and document the result. If the agreement is silent on valuation, a comprehensive valuation becomes even more critical.

Valuation Methods

Several methods can be used to value a business in the context of a share buyback between partners:

1

EBITDA multiples

The most common approach for SMEs. The enterprise value is estimated by applying a market multiple to the company's normalized EBITDA.

2

Discounted cash flow (DCF)

Future expected cash flows are projected and discounted to present value. Useful for businesses with strong growth prospects.

3

Asset-based approach

The value is based on the company's net assets, adjusted to fair market value. Often used for asset-heavy businesses.

4

Formula specified in the agreement

If the shareholders' agreement prescribes a specific formula, that formula must be applied. A valuation can verify the inputs.

5

Negotiated value with documentation

Partners agree on a price supported by financial data and a professional valuation report.

Enterprise Value vs. Share Value

Many partners confuse the enterprise value with the value of their shares. These are different concepts. The share value is derived from the enterprise value after several adjustments:

  • Subtract total debt (loans, lines of credit, obligations)
  • Add excess cash and liquid investments
  • Adjust for non-operating assets or liabilities
  • Account for working capital surplus or deficit
  • Consider the rights and restrictions attached to each share class
  • Apply any minority or control premiums/discounts if applicable

A professional valuation clearly documents these adjustments and provides a transparent bridge from enterprise value to equity value, which is essential for a fair transaction between partners.

Frequently Asked Questions

How do you determine the value of a partner's shares?

The value of a partner's shares is determined by first establishing the enterprise value using recognized methods (EBITDA multiples, DCF, asset-based), then adjusting for debt, excess cash, non-operating assets, and share class rights to arrive at the equity value attributable to the specific shares being transacted.

Why get a business valuation before buying back shares?

A valuation establishes a documented, defensible fair market value that both parties can reference. It reduces disagreements, supports advisors, provides a basis for financing, and documents the transaction for tax purposes.

Does the shareholders' agreement always determine the price?

Not always. Some agreements specify a method, formula, or fixed value, while others are silent on valuation. Even when a method is specified, a professional valuation is often needed to apply it correctly and document the result.

What is the difference between enterprise value and share value?

Enterprise value represents the total economic value of the business operations. Share value is what remains for the shareholders after adjusting for debt, excess cash, non-operating assets, working capital, and share class rights. In a buyback, the transaction is based on share value.

What is a shotgun clause?

A shotgun clause (also called a buy-sell clause) is a provision in a shareholders' agreement that allows one partner to offer to buy the other's shares at a specified price. The other partner must either accept the offer or buy the offering partner's shares at the same price. A valuation helps inform the pricing decision.

Can you use book value to buy back a partner's shares?

Book value is an accounting concept that often significantly understates the actual fair market value of a business. Using book value alone can result in an unfair price. A professional valuation considers earnings, growth, intangible assets, and market conditions to determine a more accurate value.

What documents do I need to prepare?

You will need financial statements, a general ledger, debt and asset details, cash balances, revenue breakdown, EBITDA history, the shareholders' agreement, share capital structure, corporate registers, major contracts, and information on key risks. A complete list is provided above.

Can Hadaly resolve a conflict between partners?

Hadaly does not mediate or resolve conflicts. Hadaly provides an objective, data-driven business valuation that can serve as a neutral reference point for discussions between partners and their advisors. For conflict resolution, consult a lawyer or mediator.

When should the valuation be done?

Ideally, as early as possible in the process. Getting a valuation before negotiations begin provides a factual basis for discussions and reduces the risk of disagreements escalating. If a triggering event has occurred (departure, death, shotgun clause), the valuation should be done promptly.
