Navigating Deal Structures with Earnouts & Contingent Payments
When a technology company goes to market, founders and shareholders often fixate on the headline number, the total enterprise value cited in the letter of intent. But in practice, what lands in your bank account at closing can look very different from what was announced. Earnouts and contingent payment structures are among the most powerful, and most misunderstood, tools in modern M&A deal design. Understanding how they work isn't just academic; it directly determines your economic outcome.
Why Earnouts Exist
Earnouts emerge from a fundamental tension in any deal: the buyer and seller disagree on value. Sellers believe their business will perform strongly post-close. Buyers want protection against paying for growth that doesn't materialize. An earnout bridges this gap, deferring a portion of the purchase price and tying it to defined milestones after close.
In technology M&A, earnouts are particularly common in SaaS businesses with high growth trajectories, situations where the seller's continued involvement is operationally critical, or markets where forward projections carry meaningful uncertainty. On the surface they seem like a reasonable compromise. In practice, they introduce complexity that demands careful attention.
The Devil Is in the Definitions
The most consequential element of any earnout is how the metric is defined. Revenue-based earnouts are common, but "revenue" is not a neutral term. Does it mean recognized revenue or bookings? How are renewals treated? What happens to pipeline deals signed post-close under the buyer's paper?
EBITDA-based earnouts carry additional exposure. Post-close, acquirers often allocate corporate overhead, add headcount, or restructure cost centers in ways that erode the margin sellers were earning against. Without tight contractual protections, these decisions sit entirely within the buyer's discretion. Sellers should also scrutinize the earnout period, measurement cadence, acceleration provisions in the event of a subsequent sale, and whether the buyer is obligated to actively support earnout achievement, or merely prohibited from deliberately frustrating it. These are not equivalent protections.
What the Numbers Actually Show
Consider a simplified scenario: a software company is sold for $50mm, with $35mm at close and $15mm subject to an earnout tied to reaching $12mm ARR within 24 months. At signing, the business was tracking at $9mm ARR with strong momentum. It looks achievable.
Post-close, the buyer integrates the sales team into its broader go-to-market motion, rebrands the product, and redirects certain customer segments toward its legacy platform. The business reaches $11.2mm ARR by month 24, real progress, but the threshold was binary. The seller receives nothing on that $15mm tranche. The effective purchase price was $35mm.
This is not a hypothetical edge case. The lesson is not that earnouts are inherently adversarial, but that their design determines whether they represent a credible path to additional consideration or a mechanism that systematically favors the buyer. Sellers should push for tiered or sliding-scale structures over binary thresholds, explicit operational covenants, independent audit rights, and clear dispute resolution mechanisms.
Beyond Earnouts: The Broader Toolkit
Earnouts attract the most attention, but they are one instrument in a wider set of contingent consideration structures. Each carries a distinct risk and timing profile.
Milestone Payments are event-driven rather than performance-based, triggered by a specific, discrete outcome such as a product integration, contract retention, or regulatory approval. They are often cleaner to administer than earnouts because the trigger is binary and objectively verifiable. The risk lies in scoping. A milestone tied to "successful product integration" sounds precise, but without defining who signs off, by what standard, and against what timeline, sellers face the same definitional disputes that plague poorly structured earnouts. Precision in drafting is everything.
Escrow and Holdback Provisions operate differently, they are not about future upside but about protecting the buyer against post-close risk. Typically 5% to 15% of the purchase price is held in escrow for 12 to 18 months as a fund against indemnification claims for breaches of representations and warranties. From the seller's perspective, this is consideration already earned, simply not yet released. The risk is that buyers assert claims that are speculative or inflated. Sellers should negotiate hard on escrow size, duration, and release mechanics. It is also worth exploring rep and warranty insurance as an alternative, its growing availability in mid-market tech deals has meaningfully reduced the need for large holdbacks.
Equity Rollover is common in sponsor-led transactions, where sellers are asked to reinvest a portion of proceeds into the acquiring or combined entity. It functions like contingent consideration in that a meaningful share of the seller's economic outcome is deferred, dependent on a future liquidity event. Rollover equity can generate a compelling "second bite" if the buyer has a credible value creation thesis and a clear exit pathway. But sellers need to understand the valuation at which they are rolling in, the waterfall governing how proceeds are distributed at exit, any governance rights as a minority holder, and a realistic timeline to liquidity.
The Advisory Lens
The right configuration of upfront cash, earnouts, milestone payments, escrow, and rollover equity depends on the specific dynamics of each transaction. From an advisory standpoint, the goal is to maximize not just the headline number, but the certainty-weighted value of total consideration, understanding what each structure delivers in the realistic case, not just the best case.
Getting to market with the right buyers is the first challenge. Ensuring the terms of the transaction reflect the true value of what you've built is the second, and it is where real shareholder outcomes are decided.
Navigating these structures requires both transactional experience and a deep understanding of the technology landscape. If you're considering a sale process or want to understand how your business might be valued and structured in today's market, we'd welcome the conversation.
