When a Rushed Day-One Plan Cost a Mississauga Earnout

The situation

Fernanda, Biniam and Meron had built a commercial electrical contracting business in Mississauga over close to fifteen years. Fernanda led the company's internal IT support desk and the systems that kept dispatch, billing and customer records running. Biniam was a master electrician who ran field operations and had trained most of the company's journeymen personally. Meron handled operations and the customer-facing side of the business. Together they owned the company outright, having grown it from a handful of commercial accounts into a business with a stable roster of long-term clients across the region.

A larger facilities services group made an offer to acquire the business for total consideration of roughly $24 million. The structure was typical for a deal of this size: most of the price was paid in cash at closing, with a further $4 million payable over eighteen months as an earnout tied to how much of the company's existing customer revenue the buyer retained after closing. All three owners agreed to stay on in management roles through the earnout period, since their ongoing efforts, and the buyer's, would both affect whether the target was met. For Fernanda, Biniam and Meron, the earnout represented a meaningful share of their total return on fifteen years of work, so getting the underlying agreement right mattered as much as the headline price.

Our firm acted for Fernanda, Biniam and Meron in negotiating and closing the sale. Because none of them had sold a business before, a significant part of the engagement was explaining how the mechanics of an earnout actually work, where the risk in that structure sits, and what protections were realistic to ask a buyer to accept without derailing the deal.

The integration that went wrong

An earnout only pays out if the metric it is tied to is actually achieved, and in a customer-retention earnout, the buyer controls most of the variables that determine that outcome. This is the structural tension in almost every earnout: the seller is paid based on results the buyer largely produces. Anticipating this, our team had negotiated a covenant in the purchase agreement requiring the buyer to operate the business in the ordinary course during the earnout period and not to take deliberate action designed to reduce the earnout payment. We also flagged, before closing, that the value of that covenant would only be tested once integration actually began.

The trouble started in the buyer's first week of ownership. The buyer had its own template for post-acquisition integration, built for absorbing smaller service companies quickly, and applied it on a fixed timetable rather than one adapted to this business. Field staff, including several of Biniam's most experienced journeymen, were moved onto the buyer's payroll and benefits system immediately, with the changes explained in a single group email rather than in person or through Biniam, who they actually reported to day to day. Two electricians resigned within the month, one of them taking a long-standing commercial client's site work with him informally after being recruited by a competitor.

On the customer side, the problem was more technical. Many of the company's larger service contracts contained a standard clause requiring the customer's consent before the contract could be assigned to a new owner following a change of control. The buyer's integration team sent a generic notice-of-acquisition letter to the full customer list without first confirming which contracts required consent and without involving Meron, who had the existing relationships and would ordinarily have made those calls personally. Three commercial customers, uneasy about the change and unclear on who they were now dealing with, exercised a right to terminate on notice rather than consent to the assignment. Combined, the departures and the terminations wiped out close to a third of the customer revenue the earnout was measured against, within the first two months of the eighteen-month period.

What we did

1. Reviewed the purchase agreement for leverage. The ordinary-course covenant negotiated at closing gave the sellers a contractual basis to challenge the shortfall, rather than simply absorbing it as bad luck. We assessed whether the buyer's conduct, sending notices without consent review and restructuring staff terms without consultation, breached that covenant.
2. Documented the causal chain. We worked with Fernanda, Biniam and Meron to build a clear record connecting specific buyer decisions to specific customer terminations and staff departures, including timelines, correspondence and the contract clauses that were mishandled. An earnout dispute turns on proof, not general dissatisfaction with how the buyer ran things.
3. Invoked the earnout adjustment mechanism. The purchase agreement included a dispute process for calculating the earnout, allowing the sellers to dispute the buyer's calculation within a set window. We used that process formally, rather than relying on informal pressure, which kept the sellers' claim from being time-barred.
4. Negotiated directly with the buyer's counsel. Litigating an earnout dispute is slow and expensive relative to the amount often in question, so our priority was a negotiated adjustment. We proposed a revised calculation that added back the revenue lost to the three terminated contracts, on the basis that the terminations were caused by the buyer's own mishandling of the consent process rather than any change in the customers' underlying satisfaction.
5. Accepted what could not be recovered. The revenue lost to the two departing electricians was harder to attribute contractually, since staff turnover after an acquisition is common and not automatically the buyer's fault. We advised the clients honestly that this portion of the shortfall was unlikely to be recoverable, and focused the negotiation on the stronger claim.

The outcome

The buyer, facing a documented covenant breach on the customer-notice issue and wanting to avoid a dispute that would delay the balance of the earnout period, agreed to a revised calculation. Of the roughly $1.9 million shortfall the flawed integration had created against the $4 million earnout target, about $1.1 million was restored through the adjusted calculation. The remaining shortfall, tied to the staff departures, was not recovered.

This was a genuine loss for Fernanda, Biniam and Meron, and it is worth being direct about that. They received less than the full earnout they had been counting on when they agreed to stay on and help the business succeed under new ownership. But the outcome was meaningfully better than it would have been without the covenant negotiated at closing or the formal dispute process invoked afterward. Without that groundwork, the buyer would have had no contractual reason to revisit its own calculation at all, and the full $1.9 million would likely have simply been lost.

The experience also changed how the three of them approached the remainder of the earnout period. Meron began insisting on being copied on all customer-facing communication from the buyer's integration team, and the buyer, having been through one dispute, was noticeably more careful for the rest of the eighteen months.
