The Buyout Formula That Almost Split Three Sisters' Sale

A private equity fund offered sixty-five million dollars for a family manufacturing business without a formal sale process, and only then did anyone notice the family's own agreement did not say how to divide it.

The situation

Sixty-five million dollars. That was the number a private equity fund put on the table for Chantal's manufacturing business in Elliot Lake, delivered in a single phone call rather than through the structured, multi-bidder sale process most companies of that size go through. No investment bank had been retained. No confidential information memorandum had gone out to a dozen prospective buyers. The fund's operating partner had simply called Chantal directly, having identified the business through an industry contact, and asked whether the family would consider selling.

The business had been built over three decades and was jointly owned by three sisters. Chantal ran it day to day and held the largest block of shares. Danielle, a second sister, held a meaningful minority stake but had stepped back from operations years earlier to raise a family. Azadeh, the third sister, was a specialist physician in a different city entirely; she had never worked a day in the business and held her shares mainly as an inheritance from their father, who had founded the company.

For Chantal, the appeal of a direct approach was obvious. A banker-run process could take the better part of a year, involve dozens of confidentiality agreements, multiple rounds of management presentations, and no guarantee of a better price at the end of it. The private equity buyer was offering to move quickly, with a defined number and a defined timeline. Chantal's priority was not squeezing out the last few million dollars of value. It was closing a deal she understood, on a schedule she could plan around, without the business's staff and customers hearing rumours of a prolonged sale campaign.

Danielle and Azadeh were less sure. Neither had been involved in negotiating the number, and both worried that going straight to one buyer, without testing the market, meant leaving money on the table. Azadeh in particular, comfortable in her own career with no urgent need for liquidity, wanted reassurance that the family was not underselling an asset their father had spent his working life building. The family came to us not because the deal was in trouble, but because nobody, including the buyer's own lawyers, had yet worked through how a lump sum offered to the company would actually convert into three separate payments to three shareholders who had never formalized how that split should work.

The gap nobody had noticed

The three sisters had a shareholders' agreement, drafted many years earlier when their father transferred the business into their joint names for estate planning purposes. It was a reasonable document for its time. It set out how disputes among the sisters would be resolved, restricted transfers to outsiders without consent, and included a formula for valuing shares if one sister wanted to exit or if the sisters could not agree on the company's direction.

What it did not do, because nobody had anticipated a sale of this kind when it was written, was say anything about how a third-party acquisition should be structured or priced among the sisters. The formula in the agreement was built for a buyout between the sisters themselves: a book-value calculation meant to settle an internal dispute fairly, not a mechanism for allocating an arm's length sale price agreed with an outside buyer. When we sat down with the private equity fund's proposed purchase terms, including a working capital adjustment, an escrow holdback against future claims, and earn-out payments tied to the business meeting targets over the following two years, we found that the sisters' own agreement gave no guidance on how any of that should be shared.

Applying the old formula literally would have handed Danielle and Azadeh a smaller share of the total consideration than a straightforward pro-rata split of the sale price, because the formula discounted for factors, like lack of control and lack of marketability, that made sense for an internal buyout but had no place in a genuine sale to an outsider. Chantal, who held more shares and had negotiated the deal, had not set out to disadvantage her sisters. She had simply never looked closely at what the old agreement actually said, because the family had never needed to before.

This is the kind of gap that surfaces in almost every family-owned sale sooner or later: a governance document written for one purpose gets treated as though it answers a different question entirely. It rarely comes from bad faith. It comes from documents drafted for a hypothetical dispute being asked, years later, to do the very different job of dividing real money from a real buyer. Left unresolved, it is exactly the sort of issue that turns a clean transaction into a family falling-out, with siblings on opposite sides of a negotiating table they never expected to be at.

What we did

  1. Reviewed the shareholders' agreement against the buyer's term sheet line by line, identifying every point where the old buyout formula and the new sale structure gave conflicting answers. This mattered because the family was working from an assumption that the agreement already covered the sale, and only a clause-by-clause comparison against the actual purchase terms could show them exactly where that assumption broke down, before disagreement had a chance to become personal.
  2. Modeled three allocation scenarios — the strict formula, a straight pro-rata split, and a middle-ground approach — showing each sister in dollar terms what the gap actually meant for her own payment at closing. Putting real numbers beside each option mattered because the dispute was far easier to resolve once it stopped being an abstract disagreement about fairness and became a number each sister could see for herself.
  3. Negotiated a side agreement among the sisters that superseded the old formula for this transaction only, leaving the original shareholders' agreement in place for any future dispute but establishing a clear, pro-rata basis, adjusted only for a small recognition of Chantal's operating role, for splitting this particular sale. Confining the change to this one transaction meant nobody had to reopen or rewrite the family's underlying governance document under time pressure.
  4. Renegotiated the escrow and earn-out terms with the buyer so that holdbacks and future contingent payments would track each sister's ownership percentage automatically, rather than defaulting to Chantal alone as the operating shareholder. This was the right move because two of the three sisters had no ability to influence whether the earn-out targets were met after closing, and a structure that left the risk sitting only with them would have been unfair on its face.
  5. Built a timeline the family could rely on, setting internal deadlines for each stage of due diligence and documentation and circulating them to all three sisters in writing. This addressed Chantal's central concern directly: she wanted to know, at every stage, roughly how many weeks remained rather than face a moving target, and a written schedule gave her and her sisters something concrete to check progress against.
  6. Coordinated separate independent advice for Danielle and Azadeh on the allocation compromise, arranging counsel who acted for them alone rather than letting them rely informally on the analysis prepared for Chantal's side of the file. That separation meant neither sister could later say she had been steered by counsel acting mainly for Chantal, which protected the deal itself against a future claim that the family agreement had been unfair.
  7. Managed the buyer's due diligence requests on a fixed weekly cadence, pushing back on requests that fell outside the deal's original scope and keeping the process on the schedule the family had been promised. This kept the file from expanding the way off-market deals often do once a buyer senses the seller wants certainty more than leverage, and it protected the predictable pace Chantal had asked for from the outset.

The outcome

The deal closed at the original sixty-five million dollar headline price, with the escrow and earn-out mechanics restructured so that all three sisters carried the contingent payments in the same proportion as their ownership. Under the side agreement, Danielle and Azadeh received a modestly larger share of the immediate closing payment than the old formula would have given them, while Chantal accepted a small premium for her ongoing operational role rather than the outsized allocation the original document would have technically supported.

Nobody got everything they might have pushed for in a longer, harder-fought negotiation. Azadeh, who had wanted more certainty that the family was not underselling, never got a competing offer to compare against, because the family chose not to run a wider process. Chantal gave up some of the allocation advantage the old formula would have handed her, in exchange for keeping her sisters aligned and the deal moving on schedule. That tradeoff was the point: the family valued a predictable, contained negotiation among themselves over a maximized outcome that risked months of disagreement or, worse, one sister refusing to sign.

The transaction closed within the timeline Chantal had originally hoped for when the buyer first called. The earn-out period is still running, and because the contingent payments are now structured to flow to all three sisters proportionally, none of them has an incentive to second-guess how the others are managing the transition. The side agreement did not resolve every question the original shareholders' agreement left open for future situations, and the family has since asked us to help update that underlying document so a future sale, or a future dispute, does not surface the same blind spot again.

What you can learn from this

  • If your business is jointly owned, check whether your shareholders' agreement actually addresses a third-party sale, not just a buyout among the owners themselves. Many older agreements were written for one scenario and quietly assumed to cover the other, which only becomes visible once a real offer is on the table.
  • A fast, off-market offer can be a legitimate reason to skip a lengthy sale process, but speed should never substitute for reading your own governance documents carefully before you agree on how proceeds will be split among co-owners.
  • When co-owners have different levels of involvement in a business, expect they will value a sale differently too. Surfacing those differences early, in concrete dollar terms, prevents them from turning into resentment after the deal has already closed.
  • Escrow holdbacks and earn-outs should generally track ownership percentages unless everyone has agreed otherwise in writing. Do not let a default structure quietly shift risk onto owners who have no say in whether post-closing targets are met.
  • Independent advice for minority co-owners is not a formality. It protects the deal itself, by making it far harder for anyone to challenge the fairness of an allocation compromise after the money has already changed hands.
