Minority Shareholders Fight a Locked-Box Price in a Family Sale

The situation

Camila worked as a call-centre representative. Her sister Valentina worked as a bookkeeper. Neither had ever negotiated a business sale, but both held minority shares in a Kitchener manufacturing company their father had built and left to them years earlier — 10 percent each, with the remaining 80 percent held by their aunt, Marcia, who had run the company since their father's death and made every operating decision since.

When Marcia decided to sell the company to an outside buyer for roughly $5.4 million, Camila and Valentina learned about it from a letter, not a conversation. The shareholder agreement governing the company included a drag-along clause — a provision that lets a majority shareholder force minority shareholders to sell on the same terms once the majority agrees to a deal, so a buyer can acquire the whole company without chasing down every small shareholder individually. Marcia had already signed a letter of intent with the buyer before either sister saw a number.

What the review found

Camila brought the letter of intent and the shareholder agreement to Treadstone Law before signing anything. The first thing our team flagged was the pricing mechanism. The deal used what is called a locked-box structure: the $5.4 million price was fixed based on the company's financial position as of a set date — in this case, a balance sheet roughly five months before the expected closing. From that date forward, the buyer would get the benefit of everything the business earned, and bear the risk of anything it lost, without any adjustment at closing.

The alternative structure, closing accounts, works differently: the price is provisional at signing and trued up after closing based on the company's actual financial position — cash, debt, and working capital — on the closing date itself. Locked-box deals are popular with buyers because they offer certainty and a simpler closing. Sellers can lose out if the business performs well in the gap between the locked-box date and closing, because that improvement belongs to the buyer under a pure locked-box price.

That is exactly what had happened here. The locked-box date fell just before the company won a large new contract and had its strongest quarter in years. By the time the sale was set to close, the business was carrying an estimated extra $180,000 in retained cash and profit that the locked-box price did not capture. Marcia, as majority shareholder driving the sale, had accepted the buyer's preferred structure without querying the timing. Camila and Valentina, whose 20 percent combined stake meant their share of that missed value came to roughly $36,000, had no say in the decision and had not even been shown the calculation before the letter of intent was signed.

There was a second issue. A pure locked-box price only works fairly for sellers if nothing of value leaves the company between the locked-box date and closing — no unusual dividends, bonuses, or related-party payments that would let the majority shareholder quietly extract value before handing over a company already priced as if that value still sat inside it. The draft agreement our team reviewed had no leakage protection at all.

What we did

1. Reviewed the shareholder agreement for minority protections. The drag-along clause was enforceable, but it required the sale to be on terms that were fair and disclosed to all shareholders — it did not give the majority unlimited discretion to accept any price mechanism without informing minority holders of the basis for it. That gap in disclosure gave Camila and Valentina real standing to raise the issue before closing, rather than after.
2. Raised the possibility of an oppression claim as leverage, without filing one. The Ontario Business Corporations Act allows a minority shareholder to apply to the Superior Court for a remedy where a majority shareholder's conduct is unfairly prejudicial to their interests. Our team did not recommend filing an application — that route is slow, expensive, and would likely have delayed or derailed the sale for everyone, including our clients. But a clearly written letter setting out the basis for such a claim, sent to Marcia's counsel and the buyer's counsel together, made clear that closing on the existing terms carried real legal risk.
3. Proposed switching to closing accounts. This was our first request: replace the locked-box price with a closing accounts mechanism, so the final price would reflect the company's actual position on the closing date and capture the growth that had already happened. The buyer refused. Its financing was already arranged around a fixed number, and re-opening the structure this late would have meant re-underwriting the deal and pushing closing back by months — a real cost the buyer was not willing to absorb for a price mechanism it had not caused.
4. Negotiated a ticking fee instead. When a full structural change was off the table, our team proposed the standard middle ground: a ticking fee, meaning interest calculated on the locked-box price for the period between the locked-box date and closing, paid to sellers on top of the fixed price. This is a common compromise in locked-box deals precisely because it lets a buyer keep certainty over the mechanism while giving sellers something for the time value of money and the business's interim performance, without reopening every line of the balance sheet.
5. Added leakage covenants and a warranty. The final agreement included a covenant that no dividends, bonuses, or other value could leave the company between the locked-box date and closing without the buyer's consent, backed by a specific warranty from Marcia confirming none had occurred. This protected the price both sisters were relying on from being quietly eroded before the sale closed.
6. Confirmed the ticking fee rate and reviewed the final closing statement. Our team negotiated a ticking fee of 6 percent per year on the locked-box price for the roughly five-month gap, which worked out to approximately $135,000 added to the total consideration. We reviewed the final closing statement to confirm the fee was calculated correctly and that the leakage warranty was clean before advising Camila and Valentina to proceed.

The outcome

The sale closed at the original $5.4 million locked-box price plus the negotiated ticking fee of roughly $135,000, bringing the total consideration to about $5.535 million. Camila and Valentina's combined 20 percent share of the ticking fee came to roughly $27,000 — real money, but less than the $36,000 gap our team had calculated between the locked-box date and the company's actual position at closing.

This was a partial win, and it is worth being honest about why. The buyer never agreed to a full closing-accounts adjustment, and there was no realistic way to force one without litigation that would have put the entire sale, and both sisters' liquidity from their shares, at risk. Marcia, for her part, was frustrated at having to renegotiate terms she considered already settled, and the family relationship absorbed some strain from the process. What Camila and Valentina gained was a materially better outcome than the deal they were first shown, real protection against value being stripped out of the company before closing, and a documented, defensible price instead of one accepted on faith. They did not recover every dollar of the growth the company had earned in the interim, but they recovered most of it, and they closed on terms they had actually reviewed and understood.
