If you have been following middle market M&A activity in 2026, you have likely noticed a pattern: deals are getting done, but the path from letter of intent to closing table has become more complex. Valuation gaps between what sellers believe their business is worth and what buyers are willing to pay at closing have widened, driven by a combination of geopolitical disruption, energy cost volatility, and uncertainty around forward earnings. The tool that is increasingly bridging that gap is the earnout.
An earnout is a contractual provision in which a portion of the purchase price is contingent on the business achieving specified financial targets after the sale closes. The seller receives an upfront payment at closing and has the opportunity to earn additional consideration if the business hits agreed-upon milestones, typically measured by revenue, EBITDA, or a combination of both.
Earnouts have always been part of the M&A toolkit, but their prevalence in 2026 is notably higher than in recent years. Data from Capstone Partners, RSM, and Axial all indicate that the percentage of middle market transactions including earnout provisions has increased relative to 2024 and 2025.
The reasons are straightforward. The Strait of Hormuz crisis has introduced energy and supply chain cost uncertainty that makes forward EBITDA projections harder to underwrite. Tariff policy remains in flux following the Supreme Court's February 2026 IEEPA ruling, with new Section 122 tariffs creating unpredictable input cost exposure for many businesses. Interest rates remain elevated, with the 10-year Treasury at 4.35 percent, making leveraged buyouts more sensitive to earnings risk. And the broader macroeconomic outlook has softened, with KKR lowering its 2026 U.S. GDP forecast to 2.0 percent.
The earnouts appearing in 2026 deals have some distinctive characteristics compared to prior cycles.
First, the contingent portion is generally larger. In a stable market, earnouts might represent 10 to 15 percent of total deal value. Current deal structures are showing earnout components of 20 to 30 percent in many transactions, reflecting the wider valuation gaps that need bridging.
Second, measurement periods are shorter. Rather than three-year earnout windows, many current deals use 12 to 18 month measurement periods. This reflects a belief on both sides that the current uncertainty is transitional rather than structural, and neither party wants a long tail of contingent obligations.
Third, the metrics are becoming more nuanced. Rather than simple top-line revenue targets, many earnouts now incorporate adjusted EBITDA thresholds that account for specific cost variables (energy, freight, tariff exposure) that are outside the seller's direct control. Some structures use tiered earnouts where different performance levels trigger different payout amounts, allowing for a range of outcomes rather than a binary result.
Fourth, escrow and security provisions are receiving more attention. Sellers are increasingly negotiating for earnout payments to be secured by escrow accounts or letters of credit, particularly when the buyer is a PE-backed entity that might undergo its own restructuring during the earnout period.

For a business owner evaluating an offer with an earnout component, there are several considerations that deserve careful attention.
On the positive side, an earnout can unlock total deal value that would not be available in an all-cash closing. If you are confident in your business's trajectory, accepting an earnout allows you to capture that upside while giving the buyer enough comfort to move forward. In a market where some buyers are pulling back or lowering offers, an earnout can be the difference between getting a deal done and waiting indefinitely for conditions to improve.
The risks, however, are real. Once the business is sold, the seller typically loses control over the operational decisions that drive earnout performance. A new owner might change pricing strategy, restructure the sales team, or redirect capital expenditures in ways that affect the metrics the earnout is measured against. This is why the negotiation of earnout terms is often the most consequential part of a deal.
From the buyer's side, earnouts in the current market serve multiple purposes. They allow buyers to maintain deal flow in an environment where uncertainty might otherwise cause them to sit on the sidelines. With over $1.2 trillion in private equity dry powder and growing LP pressure to deploy aging capital, PE firms cannot afford to wait for perfect conditions. Earnouts let them transact while managing downside risk.
They also provide a natural alignment of incentives during a transition period. When a seller stays involved in the business post-closing (as many middle market sellers do for 12 to 24 months), the earnout ensures that both parties are working toward the same financial outcomes.
If you are a business owner likely to encounter an earnout in your deal process, preparation makes a material difference.
Work with your M&A advisor to develop a detailed financial model that isolates the variables creating valuation uncertainty. The more precisely you can identify the sources of disagreement, the more precisely the earnout can be structured to address them.
Negotiate for objective, auditable metrics. Earnout disputes most commonly arise from ambiguous definitions. If the earnout is measured on EBITDA, the purchase agreement should specify exactly which adjustments are and are not permitted.
Consider the tax implications carefully. Earnout payments are often treated differently from upfront proceeds for tax purposes, and the structure can significantly affect after-tax proceeds. This is an area where professional tax advice is important.
Retain the right to participate in (or at least observe) the financial reporting during the earnout period. Transparency reduces the likelihood of disputes and allows for early identification of issues.
Earnouts are not a sign that the M&A market is broken. They are a sign that it is adapting. In a period of genuine uncertainty around energy costs, trade policy, and macroeconomic conditions, earnouts provide a practical mechanism for buyers and sellers to agree on transactions that might otherwise stall. For business owners considering a sale in 2026, understanding how earnouts work, how to negotiate them effectively, and how to protect your interests during the earnout period is now an essential part of deal preparation.
