Buying your sibling out
Family-business buyouts fail more often on structure than on price. Four structures we've used, and what each one costs the relationship.
The call comes in a recognisable form. A family business, second or third generation. Two or three siblings on the cap table, one or two of them actually running the thing. Something has broken (often it was breaking for a decade) and someone wants out.
The conversation that follows is almost always about price. That’s not where the decision is. The decision is about structure, and structure is what determines whether the family still speaks to each other at the next wedding.
Four structures we’ve used
1. Lump-sum buy-out, third-party financed
The exiting sibling sells their shares. The remaining shareholders (or the company itself, in a share buy-back) take on debt to pay. The exiting sibling gets cash in the bank in 60–90 days.
When it works: the company has stable cash flow, the remaining shareholders can service the debt comfortably, and the exiting sibling needs the money for a specific purpose (buying property, a settlement, etc.).
What it costs: the company’s balance sheet takes a hit. Banks are cautious about lending to fund a shareholder dispute, even a friendly one. In practice you’ll often need personal guarantees from the remaining shareholders.
2. Staged buy-out over 3–5 years
Partial payment up-front (often 30–50%), the rest paid out over three to five years in scheduled instalments. The exiting sibling’s shares are transferred in tranches, or held in escrow.
When it works: the business doesn’t have the cash flow for a lump sum, but can absorb steady payments. The exiting sibling is willing to accept some risk on the later instalments in exchange for closure now.
What it costs: the exiting sibling stays financially entangled with the business for years. If the remaining shareholders mis-manage, default, or resent the payment schedule, the bad feelings persist. This is the most common source of “we bought him out in 2018 and we’re still fighting in 2024.”
3. Earn-out tied to future performance
The exiting sibling’s shares are sold at a formula price that depends on the company’s performance over the next 2–3 years (EBITDA, revenue, etc.). Common in M&A; less common in family buy-outs, but appropriate when the exiting sibling is the one who built the business’s value.
When it works: the exiting sibling is a founder whose contribution is the hardest to price. The remaining shareholders want to pay for what actually materialises.
What it costs: the exiting sibling has an ongoing interest in the company’s numbers, and a right to audit them. Information rights are a fertile ground for the next dispute. We only recommend this structure where the family is genuinely high-trust, despite the exit.
4. Asset split
Not a buy-out at all. The company is broken into parts (often a real-estate holding arm and an operating arm) and the siblings take different arms. Each signs away claims on the other’s.
When it works: the family holds a group of businesses or assets, not a single operating company. Common with property companies, trading companies with diversified product lines, and first-generation groups that haven’t been restructured.
What it costs: valuation becomes a three-way negotiation (operating business vs. property vs. goodwill). And tax counsel becomes essential; an asset split done without tax planning will routinely cost 15–20% of the estate in avoidable stamp duty and capital gains treatment.
The structural question is the relationship question
The family that chooses a lump-sum buy-out is choosing a clean break. The one that chooses a staged payout is choosing a managed one. The one that earn-outs is choosing continued alignment. And the one that splits the assets is choosing to go separate ways with separate futures.
Those aren’t just financial choices. They’re stated positions about what the family’s future looks like. We’ve seen siblings negotiate the price brilliantly and pick the wrong structure, and lose the relationship over the next three years. We’ve also seen them accept a below-market price for the right structure and be at the next wedding.
Pick the structure first. Then negotiate the price inside it.
