When a Shotgun Clause Forced Mateo Out on His Own Terms

A health scare meant Mateo had to sell his share of an Ottawa software company fast. His business partner's response was to trigger the shotgun clause neither of them had ever expected to use.

The situation

Can I just take the number and be done with it. That was the question Mateo asked in our first call, three days after his business partner Dustin had triggered the shotgun clause in their shareholders' agreement. Mateo had recently been through a serious health diagnosis that made continuing to run a demanding software company alongside Dustin, who owned the other half of the company they had built together over nine years, no longer realistic. He had mentioned this to Dustin informally, expecting a conversation about a gradual, negotiated exit. What he got instead was a formal notice invoking the shotgun clause, offering to buy Mateo's shares at a price Mateo believed was well below what the company was actually worth, with the alternative being that Mateo could instead buy Dustin out at that same price if he preferred.

The company, an Ottawa-based software business the two had co-founded and grown to a value somewhere between two and five million dollars, had never had its shares formally valued. Mateo and Dustin had always assumed that if one of them ever left, they would work out a number together, informed by whatever an accountant told them the business was worth at the time. Neither had anticipated the mechanism actually being used this way — as a fast, one-sided move triggered the moment one partner disclosed a vulnerability.

Mateo, exhausted by his diagnosis and the treatment schedule that came with it, wanted the whole thing to be over. He told us plainly that he did not have the energy for a drawn-out fight, that he assumed shotgun clauses left no real room to negotiate once triggered, and that he was inclined to accept Dustin's price just to be finished. He wanted a fast, cheap resolution, and the temptation to simply sign what was in front of him was real.

What Mateo did not yet understand, and what became the center of our first several conversations with him, was that a shotgun clause is not a take-it-or-leave-it ultimatum in the way he assumed. It is a structured mechanism with real choices inside it, and the price Dustin had named was itself a negotiating position, not a fixed number handed down by the agreement.

What the documents showed

The shareholders' agreement Mateo and Dustin had signed years earlier, when the company was worth a fraction of its current value, contained a standard shotgun clause: either shareholder could serve notice offering to buy the other's shares at a stated price, and the recipient of that notice then had a fixed window to choose one of two things — sell their own shares at the offered price, or instead buy the other person's shares at that same price. The mechanism is designed to be self-policing, on the theory that a person naming the price has an incentive to name a fair one, since they might end up on either side of the transaction.

What the documents also showed, on close review, was that Dustin's notice complied with the formal requirements of the clause — proper written notice, a specific price, the required response window — which meant Mateo could not challenge the notice's validity on procedural grounds. This was not a case where we could argue the trigger itself was defective. Dustin had done everything the agreement required of him.

But the agreement's silence on how the price was to be determined mattered. The shotgun clause did not require Dustin to base his offer on any independent valuation, and he had not obtained one, naming instead a figure that appeared to reflect the company's value roughly two years earlier, before a period of substantial revenue growth. Mateo had no obligation to accept that figure as accurate simply because it arrived in a properly triggered notice. His actual choices were to sell at that price, to buy Dustin out at that price himself, or to attempt to negotiate a different resolution before the response window closed, recognizing that if negotiation failed, the original two choices remained his only contractual options.

The financial documents also mattered here. Company records available to both partners showed revenue had grown considerably in the two years before the notice was served, largely on the strength of contracts Mateo himself had brought in. That growth was not reflected in Dustin's offered price, giving Mateo real grounds to push back on the number even though he had no grounds to challenge the notice itself.

What we did

  1. Explained the actual mechanics of the shotgun clause before Mateo made any decision. We walked him through the fact that the clause gave him a real choice between selling and buying, not just an ultimatum to accept, and that the response window, while fixed, was long enough to gather information before committing to either path, and that accepting the first number handed to him would have foreclosed a negotiation he still had every right to have.
  2. Obtained an independent valuation of the company on an expedited basis. Given Mateo's health circumstances and the limited response window, we retained a business valuator experienced with software companies to produce a defensible valuation quickly, using the company's own financial records, so Mateo had an objective number to weigh against Dustin's offer rather than relying on instinct alone.
  3. Assessed whether buying Dustin out was realistically viable for Mateo. Given his health situation, we had a candid conversation about whether taking on sole ownership and operation of the company was something Mateo could actually manage, concluding that it was not a realistic path for him regardless of price, which narrowed the practical question to what selling price was fair rather than which of the two options to choose.
  4. Used the valuation to open a direct negotiation with Dustin before the response window closed. Rather than simply accepting or rejecting the notice, we approached Dustin's lawyer, Jordan, with the independent valuation and the revenue growth data, proposing a revised price and making clear Mateo was prepared to exercise his right to buy Dustin out instead if a fair price could not be reached.
  5. Negotiated a revised price within the shotgun clause's own framework. We reached an agreement with Dustin's side to amend the offered price upward, reflecting a portion of the revenue growth, while stopping short of the full independent valuation figure, given the time pressure and Mateo's stated preference to resolve this without prolonged conflict, a middle ground that let both sides point to the independent valuation as the basis for the number rather than either party simply capitulating.
  6. Documented the sale with appropriate protections for Mateo's exit. We negotiated release terms confirming Mateo would have no ongoing liability for the company's obligations after closing, a reasonable timeline for the sale proceeds to be paid, and confirmation of the tax treatment of the sale, so the exit was clean even though the price was a compromise, leaving Mateo free to focus on his health without a lingering dispute or unresolved obligation trailing behind the sale.

The outcome

Mateo sold his shares to Dustin at a price roughly one-fifth higher than Dustin's original offer, still below the independent valuation's midpoint but meaningfully closer to it than where the notice had started. This was not the outcome Mateo would have gotten had he simply accepted the first number, and it fell short of what a fully contested valuation dispute might eventually have produced. It is fair to describe the result as a contained loss rather than a clear win: Mateo gave up real value to reach a fast, certain resolution while managing a serious health situation, and he knew that going in.

What the negotiation avoided was worse. Left unchallenged, Dustin's original price would have undervalued Mateo's share of the growth he had personally helped generate, by an amount that, over the life of the company, represented a meaningful loss. And a contested dispute over the valuation, pursued to its conclusion, would have taken months Mateo did not have the health or the appetite to spend, for a result that was never guaranteed to land at the full independent valuation figure either.

Mateo told us afterward that the most useful thing had not been the final number itself but understanding, before he signed anything, that the shotgun clause left him more room than he had assumed. He did not get the price he might have gotten with a longer fight, and he was clear-eyed that the compromise reflected his own choice to prioritize speed and certainty over maximizing the outcome. Given his circumstances, that was a defensible trade to make, but it was a trade, not a win, and the study exists because both things can be true at once.

What you can learn from this

  • A shotgun clause is not a take-it-or-leave-it ultimatum. It gives the recipient a real choice between selling and buying, and the notice period exists to let you evaluate both before responding.
  • The price named in a shotgun clause notice is a negotiating position, not a legally required fair value. An independent valuation, even a quick one, can give you real leverage to push back on it.
  • Being tempted to accept a fast, low-effort resolution during a health crisis or other personal hardship is understandable, but get objective information first. The cost of a rushed decision does not go away because you were exhausted when you made it.
  • Revenue growth or value you personally contributed to a business is worth documenting and raising explicitly in a buyout negotiation, even where the underlying agreement does not require the other side to account for it.
  • Not every good outcome is a full win. Containing a loss and closing cleanly, on a timeline that respects your real circumstances, can be the right result even when it falls short of the ideal number.
