Earn-Outs in Tech M&A: How They Work and How to Negotiate Them

‍Earn-Outs in Tech M&A: How They Work and How to Negotiate Them

An earn-out structure defers part of a technology company's purchase price and pays it only if the business hits agreed revenue, EBITDA, or milestone targets after closing. In 2025, earn-outs appeared in 24% of private-target deals, typically running one to three years. Sellers who negotiate the metric, the period, and the protections keep control of the outcome.

Earn-outs are back in a big way, and sellers should read that as good news. Earn-outs appeared in 24% of private-target deals in 2025, up from 19% in 2014, and in 22% of deals for technology targets, well above the 14% rate the sector saw across 2014 to 2022. Buyers are using them to pay for growth they can see but cannot yet underwrite. The median earn-out potential now sits at 34% of the closing payment, so the contingent slice of a tech exit is often the difference between a good outcome and a great one.

Here's the thing: the earn-out itself is neutral. What decides whether you collect is the structure you sign. The 2026 outcome data shows that 52% of earn-outs pay at least something, yet sellers receive roughly one in five potential earn-out dollars across all deals, and earn-outs with a performance period of one year or less achieve a median 66% of their maximum. Same mechanism, very different results. The difference is negotiation.

What Is an Earn-Out Structure in Tech M&A?

An earn-out structure is a purchase price mechanism that splits consideration into two parts: a fixed amount paid at closing and a contingent amount paid later, only if the acquired business meets performance targets written into the purchase agreement. The contingent portion is earned by the business over a defined period, which is where the name comes from. Whether a buyer writes it as an earnout structure or an earn-out structure, the mechanics are identical.

Every earn-out has five moving parts, and the earn out agreement (usually a schedule to the purchase agreement) has to pin each one down:

• The metric: revenue, annual recurring revenue (ARR), gross profit, EBITDA, or a non-financial milestone such as a product release, a security certification, or a customer retention threshold.

• The target and the payout curve: a single cliff ($5M if ARR reaches $12M), a sliding scale, or tiers (base, target, stretch), almost always with a cap.

• The measurement period: one to three years is the norm, measured annually or cumulatively.

• The payment mechanics: timing, form (cash or stock), and whether the buyer can set off indemnity claims against payments.

• The operating covenants: what the buyer must and must not do with the business while the clock runs.

It helps to separate earn-outs from their cousins. Deferred payments and seller notes are fixed amounts paid later; the only risk is buyer credit. Escrows and holdbacks park part of the price against indemnity claims and flow back if nothing goes wrong. Rollover equity gives the seller a stake in the buyer rather than a contractual payment. Contingent consideration is the accounting umbrella term for every performance-linked payment; an earn-out is its most common form, and unlike profit-sharing it ends on a fixed date with a fixed cap.

An earn-out is not a discount on your business. It is a deferred, conditional slice of the price, and its value is set by the terms you negotiate, not by the headline number.

How Does an Earn-Out Work When You Sell a Technology Business?

Picture a vertical SaaS company with $6M of ARR growing 30% a year. The founder wants $30M. The buyer sees $25M on today's numbers. An earn-out structure closes the gap: $25M in cash at closing, plus up to $6M more if ARR reaches $9M within 24 months, paid on a sliding scale above $7.5M. If growth continues as projected, the total price lands at $31M. If it stalls, the buyer has paid a fair price for what existed at closing. That is the logic of every earn-out: the buyer pays for proven performance now and for projected performance later, once it is proven.

The data tells you who you will be negotiating with. US private equity buyers included an earn-out in 24% of their 2025 deals, up from 13% across 2014 to 2022, as they moved further into growth-stage technology assets. US public-company buyers used them in 18% of deals. Smaller transactions see them most often: 35% of deals with closing payments of $25M or less included an earn-out in 2025, and 29% of all deals up to $50M. The ABA 2025 Private Target Deal Points Study, which tracks public buyers of middle-market private targets, found earn-outs in 18% of agreements, down from 26% in the prior study, a sign that valuation expectations on larger deals are converging.

One more thing before you negotiate: earn-outs pay out more often than deal folklore suggests, as the 52% partial-payment rate above shows. How much gets paid depends almost entirely on the structure, which is what the rest of this guide is about.

Why Are Earn-Outs Rising in 2026 Deals?

Deal activity and buyer confidence both climbed through 2025 and into 2026. Global M&A value rose 40% to an estimated $4.9 trillion in 2025, and the buyer-seller valuation gap is easing as sellers reset expectations and buyers pay up for strategic assets. The first five months of 2026 added another 41% year over year, and technology is expected to keep attracting the highest deal values in 2026, supported by investment in AI, data, and digital infrastructure.

So why are earn-outs rising at the same time? Because buyers are paying for the future, and the future of a technology business in 2026 is arriving fast. Almost half of strategic technology deal value above $500 million in 2025 came from AI-native companies or deals that cited AI benefits. When a buyer is paying for an AI roadmap, a new pricing model, or a product months away from scale, an earn-out lets it pay a premium for the upside without underwriting the full risk on day one. For the seller, that premium is money that would not be on the table in an all-cash deal.

Market practice also moved in the seller's favor: the median earn-out potential rose from 31% to 34% of the closing payment in 2025, as noted above. Buyers are putting more upside into the structure, not less, which gives a well-advised seller more levers to pull.

Earn-outs in 2026 are a sign of buyer appetite for growth. A seller with a credible growth story gets paid for it; the structure decides how reliably.

Which Earn-Out Structure Is Best: Revenue, EBITDA, or Milestone Triggers?

The metric is the single most important term in the earn out agreement because it decides what the buyer can and cannot influence. Across the ABA deal points studies, 50% to 80% of earn-outs use EBITDA or revenue as the principal metric. Milestone triggers dominate in life sciences and are gaining ground in technology deals where the value sits in a product release, a certification, or a contract win rather than in next year's P&L. The table compares the main earnout structure options from a seller's point of view.

In our experience, revenue-based triggers are the seller-friendly default in technology deals. A buyer that folds your product into its own sales team, changes pricing, or moves hosting onto its stack will change your EBITDA whether it means to or not. Revenue survives integration better. Where a buyer insists on EBITDA, the counter is a tightly defined earn-out EBITDA with accounting policies fixed at closing, corporate allocations excluded, and a cap on new costs charged to the business.

Match the metric to the business. For a SaaS company, ARR or net revenue retention keeps everyone focused on the customers you already won. For an ecommerce brand, contribution margin after ad spend beats raw revenue. For an agency, EBITDA is hard to avoid because the buyer is buying margin, so pair it with client retention floors (see our guide to selling a digital marketing agency). For an AI or cybersecurity product that has not reached scale, a milestone you control beats a revenue number that depends on the buyer's sales force.

How Big and How Long Should an Earn-Out Be?

Two numbers set the shape of every earn-out: the share of total price at risk, and the length of the measurement period. On size, the median earn-out potential is 34% of the closing payment, and lower middle-market deals carry proportionally larger earn-outs, often half or more of the upfront payment. A useful rule: the contingent portion should be no larger than the real valuation gap. If the buyer's price and yours are 15% apart, an earn-out worth 40% of the deal is not bridging a gap; it is shifting risk.

On duration, periods of one to two years were the most common in 2025 deals at 38%, followed by one year or less at 23% and two to three years at 20%. The outcome data makes a strong case for the shorter end. Earn-outs with a performance period of one year or less achieved a median 66% of their maximum, against 36% for periods beyond three years. Shorter periods mean fewer integration changes, fewer accounting disputes, and less time for the buyer's strategy to drift away from the plan you built.

Payout curves matter as much as the headline target. A cliff is simple but brutal; missing a $10M ARR target by $50,000 should not cost you the whole payment. A sliding scale that starts paying at 85% of target and tops out at 110% keeps both sides motivated, and a stretch tier above target is how sellers capture value beyond the original ask. Push for a catch-up so a year-two overshoot makes up for a year-one shortfall, and prefer annual payments: the first one tests the buyer's reporting and good faith while there is still time to fix problems.

What Protections Should Sellers Demand in an Earn Out Agreement?

Once the business changes hands, the buyer controls the levers that drive your earn-out. Protections keep those levers honest. The starting point is more buyer-friendly than most sellers expect: buyers in the ABA deal points studies tend not to agree to operate the business consistent with past practice or to take actions to maximize the earn-out. Every protection below has to be negotiated, and the strongest sellers negotiate from the letter of intent onward.

Delaware's courts, which hear many of the largest US M&A disputes, have spent the last two years making these protections bite. In Johnson & Johnson v. Fortis Advisors (January 2026), the Delaware Supreme Court upheld findings that the buyer breached its efforts obligations on most of a $2.35 billion earn-out and fraudulently induced the seller on one milestone, while reversing on a milestone the contract had tied to a single regulatory pathway. The practice points for sellers: define the efforts standard precisely, prohibit decisions that factor in the cost of the earn-out, and say what happens if an external condition changes. In September 2026, the Court of Chancery ordered the buyer of a technology consulting firm to hand over the data its sellers needed to identify qualifying projects, and rejected its attempt to exclude projects on grounds the contract never mentioned. Courts enforce the words on the page, so put the protection on the page.

An earn-out without covenants is a promise. An earn-out with efforts, information, and acceleration clauses is a contract.

How Do You Negotiate an Earn-Out Without Losing the Deal?

Earn-out negotiation starts before the buyer proposes one. The strongest position is a competitive process with several bidders, because the fastest way to shrink an earn-out is to hold another offer with more cash at closing. Buyers propose earn-outs when they sense risk; a clean data room, defensible metrics, and a sell-side quality of earnings report remove the arguments that justify a large contingent slice. Once an earn-out is on the table, negotiate it in this order:

1. Fix the upfront price first. Agree the cash at closing for the business as it stands today, then treat the earn-out purely as upside. Negotiating the two together usually means giving back cash for contingent dollars.

2. Choose the metric you control. If you will run sales, ask for revenue or ARR. If you will run the whole P&L with budget authority, EBITDA becomes acceptable. If the buyer's team drives the outcome, insist on objectively verifiable milestones.

3. Shorten the period and add tiers. Trade a lower stretch cap for a shorter period and a sliding scale. The outcome data above shows why.

4. Get the covenants into the LOI. Efforts, information rights, and acceleration are easy to agree in principle at LOI stage and hard to win once exclusivity shifts bargaining power to the buyer.

5. Model three scenarios. Base, downside, and upside, with the earn-out formula applied to each. If the downside case pays nothing, the structure is a cliff in disguise. The model is often the most persuasive document in the room.

6. Pre-agree the accounting. A worked example schedule, signed at closing, prevents most of the disputes that end up in front of an independent accountant.

Two situations need extra care. In private equity deals, the sponsor may offer rollover equity alongside an earn-out; the two combine well, but check that add-on acquisitions during the period do not distort the metric. In cross-border deals, specify the governing law, the accounting standard (US GAAP or IFRS), the measurement currency, and whether a change in local tax or regulation adjusts the target. Buyers have legitimate concerns too: revenue pulled forward, underinvestment to protect EBITDA, and key people leaving the day the earn-out pays. Meeting those directly makes a seller-friendly structure easier for the buyer to accept.

When Should You Trade Headline Price for Certainty?

Not every earn-out is worth taking. The decision comes down to the expected value of the contingent payment, adjusted for how much control you have over the outcome. Start with the base rates. Across all earn-out deals, sellers collect about one in five potential earn-out dollars. For deals with upfront payments of $50M or less that achieve something, the median is 43 cents on the dollar; above $50M it is 67 cents. Those figures include every badly structured earn-out ever signed, so a well-negotiated one should beat them, but they are the honest starting point.

Now run the arithmetic on your own offers. Buyer A offers $20M in cash. Buyer B offers $17M in cash plus a $6M earn-out tied to ARR over 24 months. At the lower middle-market median of 43 cents on the dollar, Buyer B's earn-out is worth about $2.6M in expected value, so the offer is $19.6M, below Buyer A before timing, tax deferral, and dispute risk. For Buyer B to win, you need a credible case that your odds sit well above the base rate: a revenue metric, a short period, continued control of sales, and strong covenants. With those in place and the growth already visible in the pipeline, Buyer B's $23M headline becomes the better deal.

A simple set of rules we use with sellers:

• Take the certainty when the buyer controls the drivers, the metric is EBITDA measured after integration, the period runs beyond two years, or the covenants are thin.

• Take the earn-out when the metric is revenue or ARR, the period is 24 months or less, you keep authority over the team that delivers, the buyer has a record of paying, and the contingent portion sits on top of a fair cash price rather than replacing part of it.

• Price the risk explicitly. If the earn-out carries real risk, ask for a higher stretch cap. Upside is the buyer's cheapest concession, because it only costs them if you succeed.

A dollar of earn-out is worth whatever your control over the metric says it is worth. Negotiate the control, then decide on the price.

How Are Earn-Out Payments Taxed?

Tax treatment can move the real value of an earn-out by a wide margin, so model it before you sign. In the United States, an earn-out that forms part of the purchase price is generally taxed as capital gain, and payments received after the year of sale can usually be reported under the installment method set out in IRS Publication 537, which spreads the gain across the years in which payments arrive. Contingent payment sales follow special rules in the same publication, and part of each later payment may be treated as interest.

The trap to avoid is tying the earn-out to continued employment. If payments stop when the seller leaves, the tax authority may treat them as compensation for services rather than purchase price, which means ordinary income rates and employment taxes. Keep retention and the earn-out separate: a market-rate employment package for the role, and an earn-out that pays whether or not you remain on payroll. Other jurisdictions apply their own rules, so get country-specific advice before the LOI. This section is general information, not tax advice.

Common Earn-Out Pitfalls Sellers Can Avoid

Most earn-out disputes trace back to a handful of avoidable mistakes:

• Vague metrics. EBITDA with no definition, no policies, and no worked example invites a dispute. Define every term.

• Targets the buyer can move. If the buyer sets pricing, allocates costs, or controls the sales team, match the metric to your authority.

• Periods that outlast the plan. Beyond two years, integration and strategy changes dominate the outcome. Shorten the period and raise the stretch cap instead.

• Unlimited set-off and no acceleration. Limit set-off to finally determined claims, and make sure a sale or discontinuation of the business pays the earn-out out at an agreed amount.

• Treating the LOI as a formality. The commercial terms of the earn-out belong in the LOI. Exclusivity reduces your bargaining power the moment it starts.

Conclusion: Make the Earn-Out Structure Work for You

Earn-outs are a growing part of technology M&A because buyers want to pay for growth and sellers want to be paid for it. The 2026 data is clear on what separates the earn-outs that pay from the ones that do not: a metric the seller can influence, a period of two years or less, a sliding-scale payout with a stretch cap, and covenants that courts will enforce. Get those right and an earn-out structure becomes a way to sell above the buyer's opening number rather than a discount on it.

The best time to plan for an earn-out is before the first offer arrives, while a competitive process and a clean set of numbers are still on your side.
