Founder earn-outs in Indian M&A: structuring them so you actually get paid

An earn-out is the M&A equivalent of optimism on paper. The buyer doesn't believe the seller's forward projections; the seller does. The compromise is structuring 20-40% of the consideration as contingent on the seller hitting those projections post-close.

It feels clever at signing. It is rarely clever in practice.

Multiple studies — most prominently a Harvard Business Review analysis of US PE-backed earn-outs — have found that roughly 70% of earn-outs underperform target. The pattern repeats in Indian M&A. Founders sign earn-outs at 25% of headline value and collect 30-50% of the contingent amount on average.

Worth understanding why, and how to structure earn-outs so they actually pay.

Why earn-outs exist

Earn-outs do one job. They bridge the valuation gap between what a seller thinks the business is worth (based on forward projections) and what a buyer is willing to pay (based on confirmed trailing performance plus a haircut for execution risk).

The buyer's logic: if your projection is real, you'll hit it and earn the contingent payment. If it isn't, neither of us should pay full price today for a story that wasn't real.

The seller's logic: I know my business better than the buyer; the trajectory is real; the buyer just hasn't underwritten it yet; I'll prove them wrong post-close.

Both can be true. The data suggests the seller is usually wrong about the timing, the buyer is usually right about the haircut, and the structure of the earn-out itself decides who is happier when the smoke clears.

The three common structures

Revenue-based earn-out. The simplest. Hit revenue target by 12, 24 or 36 months post-close, receive a defined payment. Sub-targets sometimes layered (50% of target = 50% of payment, 80% = 80%, 100% = 100%). Cap usually at 100-120% of target.

Why founders like it: revenue is hard to manipulate, easy to measure, and the founder controls the sales effort.

Why founders should worry: revenue can be hit with margin destruction. The founder lowers prices, runs unprofitable promotions, books low-quality customers — earn-out pays, but the buyer is unhappy and the founder's reputation is damaged. Worse, the buyer can interfere with sales efforts (reorganise the sales team, change pricing, redirect leads) and the founder has no remedy because the contract only measured revenue.

EBITDA-based earn-out. Hit EBITDA target. Cleaner alignment with what the buyer is paying for. But EBITDA is a constructed number — it depends on what gets capitalised vs expensed, what counts as one-off, how shared costs get allocated.

Why founders should worry: the buyer controls the chart of accounts post-close. Suddenly there are new corporate overhead allocations charged to your unit, new IT system costs, new shared service fees. The trailing EBITDA you projected gets compressed by 15-20% from allocation alone, before any operational issues.

Milestone-based earn-out. Specific events — regulatory approval, contract signed, product launch, customer count — trigger defined payments. Cleanest when the milestones are objective and within the founder's control.

Why founders should worry: milestones are written in legalese, interpreted by lawyers, and disputed when payment time comes. A milestone like 'AY26 sign-off from Tier-1 customer X for product Y' sounds objective until you realise the contract doesn't define what 'sign-off' means or what counts as Tier-1.

The five traps founders fall into

Trap 1: Accepting the buyer's accounting policies. The earn-out is measured under accounting policies. The SPA either freezes the policies as of closing (good for founder) or lets the buyer apply their group policies post-close (bad for founder). We have seen earn-out targets shift 20-30% just from policy changes — revenue recognition timing, capitalisation thresholds, provisioning levels.

Fix: insist on a frozen accounting policy schedule attached to the SPA. Any deviations require seller consent or trigger pro-forma adjustments back to the frozen policies.

Trap 2: No post-close operating freedom clauses. The buyer reorganises the business post-close — moves the founder out of sales, changes the GTM, integrates customer-facing teams. The earn-out is now measured on a business the founder no longer controls.

Fix: contractual operating freedom for the earn-out period. The unit operates as a defined entity. Founder retains operating authority over specified areas (sales, pricing, product roadmap). Buyer cannot make changes that materially affect earn-out metrics without seller consent.

Trap 3: No accounting consistency clause. Even with frozen policies, the application of those policies can shift. A revenue recognition policy that allowed recognition on customer signature can be reinterpreted to require customer go-live. The policy didn't change; the application did.

Fix: explicit accounting consistency clause requiring the buyer to apply the frozen policies on the same interpretive basis as the seller did pre-close. Disputes go to a neutral accounting expert (Big Four firm not involved in the deal), whose decision is binding.

Trap 4: No anti-interference clause. Buyer can route business away from the founder's unit, accelerate the founder's exit, redirect sales leads, change incentive structures for the founder's team — all without breaching anything in a standard SPA. The earn-out underperforms; founder has no remedy.

Fix: explicit anti-interference clause listing specific actions that, if taken by the buyer, deem the earn-out paid in full. Examples: terminating the founder without cause before earn-out maturity, transferring named customer relationships to other group entities, reducing the unit's sales force below a defined headcount.

Trap 5: No acceleration on bad-leaver. If the buyer terminates the founder for cause, the earn-out is forfeited (this is standard and usually fair). If the founder leaves voluntarily, the earn-out is typically forfeited (sometimes fair, sometimes not). But what if the buyer constructively terminates the founder by making the working conditions intolerable?

Fix: define 'constructive termination' carefully — material reduction in title, responsibility, compensation, reporting line, or geographic location. Constructive termination triggers the same acceleration as termination without cause.

An earn-out without these five protections is not an earn-out. It is an option the buyer holds to pay you less if circumstances permit. The protections turn the option back into a contract.

The size question

How much of the deal should be earn-out? Indian M&A patterns we see:

Strategic acquirer of a profitable business: 10-20% earn-out, 12-24 months, revenue or EBITDA based.

Strategic acquirer of a growth business with limited profitability: 25-40% earn-out, 24-36 months, milestone or revenue based.

PE buyer: 5-15% earn-out, smaller because PE doesn't love contingent consideration and prefers rollover equity for alignment.

Roll-up consolidator: 30-50% earn-out, aggressive structures tied to retained-customer revenue, sometimes layered over 36 months.

Anything above 40% earn-out in a deal is a structural signal that the buyer and seller don't agree on the valuation. The deal isn't really closed at the headline number; it's closed at the cash-at-signing number plus an option. The seller should price accordingly — including discounting the earn-out expected value at 50-60% based on the empirical underperformance rate.

The escrow vs earn-out distinction

Worth separating earn-out from escrow. They look similar — contingent consideration held by a third party — but they serve different purposes.

Escrow protects against indemnity claims. The seller is owed the money; the buyer can claim it for breach of reps & warranties. Default position: seller gets the escrow at maturity.

Earn-out is the opposite. The buyer doesn't owe the money; the seller has to earn it. Default position: buyer keeps the money unless the seller hits the target.

Indian founders sometimes conflate the two in their headline math. A deal at ₹400 crore with ₹100 crore in escrow and ₹100 crore in earn-out is not a ₹400 crore deal. It is a ₹200 crore deal plus two contingent claims with very different probability distributions. The escrow returns at 85-95% on average; the earn-out returns at 30-50% on average.

Honest valuation math: ₹200 crore cash + ₹90 crore expected escrow + ₹40 crore expected earn-out = ₹330 crore. Not ₹400 crore.

What we negotiate in the room

When running an earn-out structure for a sell-side client, four positions we hold to:

First, the earn-out target should be inside the founder's projection, not above it. If the founder projects ₹100 crore EBITDA in Year 2, the earn-out target should be ₹85-90 crore. The buyer is paying for the upside; the founder isn't betting on the projection being right exactly.

Second, the earn-out should have a floor. Sub-target performance should still pay something. Cliff structures (hit target = full payment, miss target = zero) create perverse incentives in the final quarter.

Third, anti-interference and operating freedom clauses are non-negotiable. We will trade earn-out size for these protections. A smaller earn-out with proper protections pays better than a larger earn-out without them.

Fourth, acceleration on change of control. If the buyer is acquired during the earn-out period, the earn-out vests immediately at full target. Otherwise the founder ends up working for a third party who never signed the original deal and has no incentive to honour the contingent payment.

What founders should do at LOI

Earn-out structure should be agreed at LOI, not at SPA. Most sellers leave earn-out structure to the SPA negotiation, when the buyer's leverage is maximal. By that point, the buyer dictates structure and the seller is reduced to negotiating the number.

At LOI, the seller has leverage. The earn-out structure terms (basis, period, protections, acceleration) should be specified at IOI/LOI. If the buyer won't commit to structure in the LOI, that's a signal — they're keeping their options open.

Founders who push back at LOI often get 60-70% of what they ask for. Founders who wait for SPA get 20-30%.
