What Every Calgary Business Owner Needs to Know Before Agreeing to an Earn-Out

Selling a business is one of the most significant financial events of an owner’s life. When a buyer and seller cannot agree on a purchase price, an earn-out can seem like the perfect bridge. But what looks like a simple compromise on paper can become a source of serious dispute if the details are not handled carefully. Calgary business owners considering an earn-out arrangement need to understand exactly what they are agreeing to before signing anything.

What Is an Earn-Out, and Why Does It Come Up?

An earn-out is a contractual provision in a business sale agreement that ties a portion of the purchase price to the future performance of the business. Rather than paying the full agreed amount at closing, the buyer pays an initial sum and commits to additional payments if the business hits certain financial targets after the sale. These targets are typically tied to metrics like revenue, EBITDA (earnings before interest, taxes, depreciation, and amortization), gross profit, or net income over a defined period.

Earn-outs tend to arise when there is a valuation gap between what a seller believes the business is worth and what a buyer is willing to pay upfront. A seller who expects continued strong growth may demand a higher price; a buyer who is uncertain about that growth will push back. The earn-out allows both parties to move forward while deferring the valuation debate to the marketplace itself.

In Alberta’s business sale environment, earn-outs are common in transactions involving privately held companies, professional practices, and technology businesses where future earnings are less predictable. They can be a legitimate and effective deal structure, but only when properly negotiated and documented.

The Real Risks Hiding in an Earn-Out Agreement

The core tension in any earn-out is this: after the sale closes, the buyer controls the business. The seller, whose additional payments depend on how that business performs, no longer has direct influence over the decisions that drive performance. This creates an obvious conflict of interest that can lead to significant financial losses for sellers if the agreement is not carefully drafted.

Buyers may make legitimate business decisions, such as cutting costs, restructuring the sales team, or pivoting strategy, that inadvertently (or deliberately) suppress the metrics on which the earn-out is based. In some cases, sellers have found that buyers restructure accounting methods or allocate overhead in ways that reduce the reported profitability of the acquired business, making earn-out targets harder to hit. These are not always bad-faith moves, but the financial impact on the seller can be the same regardless of intent.

There is also the matter of integration. When a buyer merges the acquired business into an existing operation, isolating the financial performance of the target company for earn-out measurement purposes becomes complicated or even impossible. Sellers who do not address this scenario explicitly in the purchase agreement often find themselves in a dispute over numbers that cannot be cleanly attributed to the business they sold.

Key Provisions That Protect Sellers

Given these risks, the drafting of the earn-out provisions in the purchase agreement is where sellers either protect themselves or expose themselves to loss. Several clauses deserve close attention during negotiation.

The definition of the earn-out metric matters enormously. Revenue-based targets are generally more straightforward to calculate and harder to manipulate than profit-based targets because they are less susceptible to accounting adjustments. If a profit-based metric is used, the agreement should specify exactly which accounting standards apply, how overhead is allocated, and whether any related-party transactions require adjustments.

The agreement should also include an operating covenant that restricts how the buyer can run the business during the earn-out period. This might include requirements to maintain a minimum level of marketing spend, prohibit the diversion of customers or opportunities to the buyer’s other entities, or preserve the existing management team. Without these protections, a buyer has little contractual obligation to run the business in a way that gives the earn-out targets a fair chance of being achieved.

Finally, dispute resolution provisions are essential. The agreement should specify a clear process for calculating the earn-out, provide the seller with audit rights to review the relevant financial records, and establish a mechanism, such as a binding determination by an independent accountant for resolving disagreements. Sellers who do not secure these rights may find themselves with no practical way to challenge an earn-out calculation they believe is wrong.

What Buyers Should Know Too

Earn-out disputes are costly and time-consuming for buyers as well. Litigation or arbitration over earn-out payments can drag on for years, divert management attention, and damage the working relationships that make a business acquisition successful in the first place. Buyers who approach earn-out negotiations with a view to drafting fair, clear, and workable provisions tend to close faster, build goodwill with the seller, and avoid post-closing headaches.

Buyers also need to think carefully about what they are committing to when they agree to operating covenants. A covenant that restricts the buyer’s ability to integrate the acquired business, redirect resources, or respond to market conditions may create real operational constraints. Buyers should negotiate earn-out terms that reflect how they actually intend to run the business, not just what looks reasonable at the negotiating table.

Clear financial reporting obligations are in both parties’ interest. Establishing a consistent reporting format and timeline from the outset reduces the risk of miscommunication, sets appropriate expectations, and makes the earn-out period far less contentious for everyone involved.

Tax and Accounting Considerations in Alberta

Earn-outs introduce complexity not just in contract law but in tax and accounting treatment as well. Under Canadian tax law, the timing and characterization of earn-out payments can have significant implications for both the seller’s capital gains position and the buyer’s deductibility of those payments. The Canada Revenue Agency has specific rules governing how earn-out payments are treated, and the structure of the agreement can affect whether payments are treated as proceeds of disposition, adjustments to the purchase price, or something else entirely.

Alberta does not have a provincial capital gains tax separate from the federal system, but the overall tax impact of how an earn-out is structured can still be substantial. Sellers should engage both legal and tax advisors before finalizing the terms of any earn-out arrangement, as decisions made during negotiation can have consequences that last long after the earn-out period ends.

Accounting treatment under applicable financial reporting standards also matters for buyers who have reporting obligations, particularly where the acquired business is consolidated into a larger entity. Purchase price allocation, contingent consideration accounting, and subsequent remeasurement of earn-out liabilities are all areas that require careful attention from the buyer’s finance team.

Getting It Right From the Start

Earn-outs are not inherently problematic structures. When properly negotiated and clearly documented, they allow transactions to close that might otherwise fall apart, and they can align the interests of buyers and sellers during a critical transition period. The problems arise when parties rush through the drafting, rely on vague language, or fail to anticipate the scenarios that can arise once the buyer takes control.

Calgary business owners who are considering a sale involving an earn-out should prioritize getting strong legal advice before the letter of intent is signed. The letter of intent, while typically non-binding on most terms, often sets the parameters that both parties expect to follow through to the final agreement. Entering that stage without a clear understanding of how earn-out provisions work, and what protections to ask for, puts sellers at a significant disadvantage.

The difference between a well-structured earn-out and a poorly drafted one is often the difference between receiving the full value of the business you built and spending years in a dispute over payments you were counting on.
