Earnouts and Post-Closing Purchase Price Adjustments: Drafting, Measuring, and Fighting About Them

Document type: Article Practice area: Corporate — Mergers and Acquisitions Jurisdiction: United States (Delaware and federal) Last reviewed: 5 September 2026

Two different problems, often confused

A purchase price adjustment is backward-looking. The parties signed a deal based on a balance sheet as of some date; between signing and closing, the business kept operating; the adjustment reconciles the price to the balance sheet the buyer actually received at closing. It measures working capital, cash, indebtedness, and transaction expenses as of the closing, compares them to targets or to zero, and moves money accordingly. It is an accounting exercise with a right answer, in principle.

An earnout is forward-looking. The parties could not agree on what the business is worth, so part of the price is deferred and made contingent on future performance — revenue, EBITDA, a regulatory approval, a product launch, a customer renewal. It measures something that has not happened yet, under the control of a party that did not exist as the owner when the deal was signed. It is a bet with a referee, and the referee's instructions are the contract.

Why lawyers should keep them apart. They fail for different reasons, they need different dispute mechanisms, and conflating them produces a contract where the earnout is submitted to an accountant who cannot decide an efforts question and the working capital true-up goes to a court that will spend two years learning inventory reserve methodology.

Why earnouts generate so much litigation

Three structural features, present in almost every earnout, do the work.

First, the buyer controls the outcome. After closing, the buyer owns the business and decides how to run it. Every decision — pricing, headcount, integration, capital allocation, whether to book revenue in this segment or that one — moves the earnout. The seller has sold the asset and retained a claim on its performance, which is a uniquely uncomfortable position.

Second, the metric is manipulable. EBITDA depends on accounting judgment. Revenue depends on recognition timing and on which entity books the sale. Any metric that flows through a general ledger the buyer controls is a metric the buyer can influence without doing anything the contract forbids.

Third, the efforts standard is vague. "Commercially reasonable efforts to achieve the Earnout Targets" is a sentence that means very little until a court has construed it against a specific set of facts, and by then the parties have spent two years and several million dollars finding out.

The empirical consequence. A large share of Delaware Court of Chancery post-closing M&A litigation involves earnouts, and the leading opinions in the field are, essentially, all disputes about the same three features.

The implied covenant and its limits

Sellers who cannot find an express covenant that the buyer breached reach for the implied covenant of good faith and fair dealing. Delaware law is receptive in principle and stingy in application.

The doctrinal frame. Dunlap v. State Farm Fire & Casualty Co., 878 A.2d 434 (Del. 2005) states the covenant's role: it attaches to every contract and requires a party to refrain from arbitrary or unreasonable conduct that prevents the other party from receiving the fruits of the bargain. It fills gaps; it does not rewrite terms.

And the limit is real. Nemec v. Shrader, 991 A.2d 1120 (Del. 2010) refused to use the implied covenant to constrain the exercise of an express contractual right, reasoning that the covenant cannot be used to circumvent the parties' bargain and applies only to developments that could not have been anticipated — a formulation that defeats most earnout claims, because the parties could have anticipated that the buyer would run the business as it pleased and could have said so.

Applied to earnouts. Airborne Health, Inc. v. Squid Soap, LP, 984 A.2d 126 (Del. Ch. 2009) is the canonical treatment: the court recognized that a buyer with discretion over the earnout metric owes the seller a duty not to act arbitrarily or in bad faith, while emphasizing that a seller who wants operational commitments must bargain for them expressly. Winshall v. Viacom International, Inc., 76 A.3d 808 (Del. 2013) confirmed the point from the other direction, declining to imply an obligation that the parties did not include and observing that the implied covenant is not a device for rescuing a party from a bargain it now regrets.

The practical lesson for sellers. The implied covenant is a backstop against bad faith, not a substitute for operating covenants. If the seller needs the sales force maintained, the product supported, and the brand invested in, the agreement must say so with specificity — headcount floors, minimum marketing spend, a prohibition on reallocating accounts, a requirement to maintain separate books.

And the practical lesson for buyers. An express disclaimer helps but does not immunize. A clause stating that the buyer has no obligation to operate the business in any particular manner and may act in its own interest is enforceable and important — and a buyer who takes an action whose only apparent purpose was to defeat the earnout will still find itself explaining that action to a fact-finder.

Efforts clauses: what the words actually buy

Earnout agreements are full of efforts standards, and the hierarchy lawyers recite — best efforts, commercially reasonable efforts, reasonable efforts, good faith efforts — is far less settled in the case law than in the drafting memoranda.

Best efforts, classically construed. Bloor v. Falstaff Brewing Corp., 601 F.2d 609 (2d Cir. 1979) is the case every commercial lawyer learns: a brewer that acquired a beer brand and agreed to use best efforts to promote and maintain a high volume of sales was held liable when it slashed marketing, closed distribution, and let the brand decay, because best efforts required more than pursuing its own short-term profitability. Best efforts does not mean every effort regardless of cost — it means an obligation to act with diligence and good faith toward the object, giving the counterparty's interest real weight.

And the same idea in an acquisition setting. Sonoran Scanners, Inc. v. PerkinElmer, Inc., 585 F.3d 535 (1st Cir. 2009) considered a technology acquisition with contingent payments tied to commercialization and an express best efforts commitment; the court declined to read the obligation out of the contract merely because the buyer's business judgment favored abandoning the product line, and treated the scope of the duty as a question that depended on the surrounding circumstances rather than on the label alone.

What Delaware has done with "commercially reasonable efforts" in the earnout context. In Lazard Technology Partners, LLC v. Qinetiq North America Operations LLC, 114 A.3d 193 (Del. 2015), the Delaware Supreme Court addressed a milestone agreement providing that the buyer would not take any action intended to reduce or avoid the earnout, and held that the provision required proof of intent — the buyer's business decisions were not actionable simply because they had the effect of reducing the earnout. The lesson is that the language chosen governs: a covenant framed around intent buys the seller much less than a covenant framed around conduct.

The drafting consequence. Do not rely on the label. Specify:

The objective. Efforts to do what, exactly? Achieve the target, or operate the business consistently with past practice, or maintain a specified function?
The benchmark. Efforts consistent with the buyer's own practice for comparable businesses; or consistent with the target's practice in the twelve months before closing; or measured against a stated budget.
The floors. Minimum headcount, minimum marketing spend, retention of named employees, maintenance of specified customer relationships.
The prohibitions. No reallocation of the target's customers to other business units; no transfer of the target's products to a different price list; no change to revenue recognition policy for the earnout metric.
The intent language, or its absence. A seller should resist "action intended to reduce the Earnout" and press for "action that reduces the Earnout other than in the ordinary course consistent with past practice."

The accounting principles hierarchy

The single most consequential technical drafting question in both earnouts and working capital adjustments is: when the target's historical accounting practice conflicts with GAAP, which controls?

Why it matters. Every private company has accounting practices that are consistent, defensible, and not quite GAAP — an inventory reserve methodology, a revenue cut-off convention, a capitalization policy for internally developed software, a treatment of accrued vacation. The targets in the agreement were negotiated against the historical numbers. If the closing statement is prepared under strict GAAP, the buyer can restate the balance sheet and extract a very large adjustment from a target that was never calibrated to GAAP figures.

The leading case. Chicago Bridge & Iron Co. N.V. v. Westinghouse Electric Co., 166 A.3d 912 (Del. 2017) arose from exactly this. The buyer submitted an enormous purchase price adjustment based on a wholesale GAAP-based restatement of the seller's project accounting. The Delaware Supreme Court read the purchase agreement as a whole — including a provision stating that the buyer's sole remedy for financial statement issues was the representations, which had been eliminated — and held that the true-up mechanism was a narrow instrument for measuring changes between signing and closing on a consistent basis, not a vehicle for relitigating the seller's accounting policies. The adjustment provision measures change; it does not re-price the deal.

The drafting answer. State an explicit hierarchy, in order:

The specific accounting policies, methodologies, and elections set out in an exhibit to the agreement, including a sample calculation of the metric using actual historical data;
Then, the accounting principles, practices, methodologies, and policies used in preparing the target's audited (or reviewed) financial statements for the most recent fiscal year, applied on a consistent basis;
Then, GAAP.

And add the anti-restatement sentence:

No change in reserves, accruals, estimates, or judgments shall be made in the preparation of the Closing Statement except to the extent the underlying facts and circumstances have changed, and no methodology or election shall be applied in the preparation of the Closing Statement that was not applied in the preparation of the Sample Calculation.

The sample calculation is the most valuable page in the agreement. It converts an abstract standard into an arithmetic example the parties both signed. Where there is a sample calculation, disputes shrink to whether a line item was computed the way the sample computed it. Where there is not, disputes expand to what GAAP requires — a question on which two competent accountants will disagree at length and at expense.

Designing the dispute mechanism

The default architecture. The buyer prepares a closing statement or earnout statement; the seller has a review period with access to books, records, and personnel; the seller delivers an objection notice identifying disputed items with reasonable specificity and its position on each; the parties negotiate for a period; unresolved items go to an independent accountant.

Every one of those steps needs drafting attention.

The preparation period. Sixty to ninety days is typical; shorter periods for simple metrics. Specify whether the buyer or the seller prepares — buyer preparation is the norm for working capital, and seller-friendly deals sometimes give preparation to the seller for the earnout metric.

Access. The seller's ability to test the numbers is the whole value of the objection right. Specify access to the books and records, the underlying work papers, the accounting personnel, and — critically — the buyer's own consolidation entries where the metric can be affected by them. Access clauses that grant "reasonable access during normal business hours" and nothing more are inadequate.

Deemed acceptance. If no objection is delivered in the window, the statement becomes final. This is enforced strictly. It is also the reason seller representatives calendar the deadline on the day the statement arrives.

Specificity of objection. Most agreements require the objection notice to identify each disputed item and the seller's proposed amount. Items not objected to are final, which means a seller who objects generically may lose the ability to litigate specifics later.

The independent accountant. The most important design choices:

Selection. Name the firm, or name a mechanism (each side nominates, the nominees select) with a deadline and a default.
Independence. Confirm the firm has no relationship with either party or with the target; conflicts are common with the Big Four and a named-firm clause frequently fails at the moment of use.
Scope. The accountant decides only the items identified in the objection notice and remaining in dispute — not the whole statement.
Baseball or discretion. Many agreements require the accountant to select one of the two parties' positions for each item; others permit any value between them. Baseball resolution disciplines positions; discretionary resolution invites splitting.
Standard. The accountant applies the agreement's accounting hierarchy, not its own view of best practice, and is instructed in writing to that effect.
Role. State that the accountant acts as an expert and not as an arbitrator, or as an arbitrator — and understand the consequence, because it determines whether the determination is reviewable under 9 U.S.C. § 10 and confirmable under 9 U.S.C. § 9, or whether it is a contractual determination reviewable only for manifest disregard of the submission.
Procedure. Written submissions only, or a hearing; a page limit; a schedule; a deadline for the determination; whether ex parte communication is permitted (it should not be).
Fees. Split evenly, or allocated in proportion to the degree each party prevailed — the proportional allocation is a real deterrent to overreaching positions.

The mechanism must fit the dispute. An independent accountant is the right decision-maker for whether a receivable reserve was computed consistently with the sample calculation. It is the wrong decision-maker for whether the buyer breached an operating covenant by moving the sales force. Agreements that route everything to the accountant end up in court on the threshold question of what the accountant may decide — a costly detour that thoughtful drafting avoids by carving out breach claims expressly and sending them to litigation or arbitration.

Worked example: the Torrance Instruments earnout

Delia Marchetti built Torrance Instruments over eighteen years into a maker of calibration equipment with forty-two million in revenue and nine million of EBITDA. Halberd Industrial, a strategic buyer, offered ninety million at closing plus an earnout of up to thirty million over three years tied to Torrance's EBITDA.

The gap that produced the earnout. Delia valued the business on a pipeline that included two large aerospace contracts not yet signed. Halberd would not pay for unsigned contracts. The earnout was the compromise, and it was — as most earnouts are — a way of not deciding.

What the first draft said. "Earnout Payments shall be based on the EBITDA of the Business for each Earnout Year, determined in accordance with GAAP. Buyer shall use commercially reasonable efforts to operate the Business so as to achieve the Earnout Targets."

What was wrong with it, in order of severity.

"The Business" was undefined. After integration, Torrance's products would be sold through Halberd's channel to Halberd's customers by Halberd's salespeople. Whose revenue is that?

"EBITDA... in accordance with GAAP" ignored the allocation problem. Halberd would allocate corporate overhead, IT, insurance, and legal to the business unit. Every dollar allocated is a dollar of EBITDA gone. GAAP does not say how much.

"Commercially reasonable efforts" gave Delia almost nothing, especially if a court read it, as in Lazard, to require proof of intent.

There was no dispute mechanism at all for the earnout — the agreement's working capital accountant provision did not reach it.

What the negotiated version said instead.

Definitions. "Business" was defined as the Torrance product lines listed on a schedule by SKU, plus successor and derivative products, wherever sold and by whomever sold, with revenue attributed to the Business on the basis of the product sold rather than the entity that booked it.

EBITDA was defined by reference to a sample calculation applying Torrance's historical policies to its last fiscal year, with an exhibit listing eleven specific adjustments: overhead allocation capped at a fixed dollar amount escalating at three percent annually; no allocation of Halberd corporate development, investor relations, or acquisition costs; transaction expenses excluded; purchase accounting effects excluded; non-cash stock compensation excluded; and a stated transfer price for intercompany sales.

Operating covenants replaced the efforts clause: maintain the Torrance sales organization at not fewer than eighteen quota-carrying representatives; maintain marketing spend at not less than the historical percentage of revenue; keep separate books for the Business; do not discontinue any listed product line without Delia's consent; do not change the pricing of listed products by more than ten percent without consultation; give Torrance products no less favorable treatment in the channel than comparable Halberd products. Plus a covenant not to take any action, whether or not intended to reduce the earnout, that would reduce EBITDA other than in the ordinary course consistent with past practice.

Acceleration. If Halberd sold the Business, discontinued the product lines, or breached a listed operating covenant, the full remaining earnout became payable — which is the provision that makes the operating covenants self-enforcing, because the remedy is liquidated rather than litigated.

Dispute mechanism. Buyer prepares within sixty days; Delia (as seller representative) gets ninety days and full access including Halberd's allocation work papers; objection with specificity; thirty days of negotiation; accounting disputes to a named independent accountant on a baseball basis with fees allocated in proportion to success; breach of operating covenant claims expressly carved out and sent to the agreement's arbitration provision.

What happened. In year two, Halberd's channel chief moved three large accounts from the Torrance rep team to the enterprise team. Revenue on those accounts continued to be attributed to the Business — because the definition followed the product, not the seller — so the earnout was unaffected. A single definitional choice made two years earlier disposed of what would otherwise have been the entire case.

In year three, Halberd increased the overhead allocation. The cap held it to the scheduled amount. Delia's accountant flagged a two-hundred-thousand-dollar allocation of a Halberd-wide ERP implementation; Halberd removed it after one letter, because the exhibit was explicit.

Total post-closing litigation: none. The earnout paid twenty-six of thirty million. Delia thinks she left value on the table; Halberd thinks it overpaid. That is the sign of a well-drafted earnout.

The working capital adjustment in detail

The purchase price adjustment looks simple and is not.

The formula. Purchase price is adjusted, dollar for dollar, by the amount by which closing net working capital exceeds or falls short of a target, plus closing cash, minus closing indebtedness, minus unpaid transaction expenses. Each of the four components is a defined term, and each definition is a negotiation.

Net working capital. Current assets minus current liabilities — but which ones? The definition should be built from a line-item schedule derived from the target's own trial balance, listing each account included and each excluded. Recurring fights: deferred revenue (is it a working capital liability, and if so at what value — face, or cost to fulfil?); income tax accounts; accrued bonuses and vacation; intercompany balances; prepaid insurance; and the current portion of long-term debt, which usually belongs in indebtedness rather than working capital and must not be counted twice.

The target. Usually a trailing twelve-month average of monthly working capital, computed on the same basis as the definition, and adjusted for seasonality. Compute the target from the same schedule and the same methodology as the closing statement, or the comparison is meaningless. A target computed by the banker from summary financials and a closing statement computed by the buyer's accountants from the general ledger will differ for reasons that have nothing to do with the business.

Cash. Gross or net of outstanding checks and deposits in transit; restricted cash; cash held in foreign subsidiaries with repatriation costs; cash in escrow or as collateral. Say which.

Indebtedness. Funded debt, capital leases, deferred purchase price from the target's own prior acquisitions, accrued but unpaid interest, prepayment penalties and breakage costs, underfunded pension liabilities, related-party loans, letters of credit drawn or undrawn, and — in almost every deal — a residual "and any obligation of a similar nature" clause that produces argument. List the categories; do not rely on the residual.

Transaction expenses. Advisory fees, legal fees, change-of-control payments, transaction bonuses, and the employer portion of payroll taxes on them. The last item is routinely omitted and routinely worth money.

Two-way or one-way. A two-way adjustment moves the price in either direction. A one-way adjustment — buyer benefits from a shortfall, seller does not benefit from a surplus — appears in some seller-unfriendly deals and should be resisted or priced.

The collar. A deductible or threshold below which no adjustment is made suppresses small disputes. It also means the buyer eats the first hundred thousand of shortfall, which buyers dislike. Where used, it should be a true deductible or a true threshold, stated as such.

Escrow. An adjustment escrow, separate from the indemnity escrow, sized to the plausible range of the adjustment and released promptly on finalization. Without it, a seller that has distributed the proceeds may not be a collectible counterparty for a downward adjustment.

And the Chicago Bridge lesson applies here most directly. The Delaware Supreme Court's reading — that a true-up provision measures change on a consistent basis rather than serving as a vehicle to restate the seller's accounting — is the principle a seller invokes when the buyer's closing statement contains a nine-figure adjustment premised on new methodology. Draft to make that principle explicit rather than relying on a court to find it.

Structuring the earnout: the design choices

The metric. In rough order of manipulability, least to most: a binary event (regulatory approval, a signed contract, a product certification); revenue; gross profit; EBITDA; net income. Every step down the list adds accounting judgment the buyer controls. Sellers should push up the list; buyers push down, because down the list is where the metric actually correlates with value.

The period. One to three years is typical. Longer periods increase integration distortion and the chance that the business has been transformed beyond recognition. Shorter periods increase the chance that a good business misses through timing.

Linear or cliff. A cliff — nothing below the target, everything above — maximizes the incentive to manipulate at the margin and produces the worst disputes. A linear or tiered payout, with payment scaling between a floor and a cap, is more robust and is the better default.

Catch-up and carryforward. A cumulative earnout, where a shortfall in year one can be made up by outperformance in year two, reduces timing luck. Sellers should ask for it; buyers should agree to it, because it also reduces the seller's incentive to push revenue into an early period.

Cap and floor. Almost always capped. A floor — a minimum payment regardless of performance — converts part of the earnout into deferred purchase price and is a useful negotiating currency.

Acceleration triggers. Sale of the business, discontinuation of the product line, breach of an operating covenant, insolvency of the buyer, termination of key seller employees without cause. Acceleration is what makes operating covenants enforceable, because it converts a breach claim requiring proof of causation and damages into a liquidated payment obligation.

Security. Earnouts are unsecured obligations of the buyer unless something is done about it. Options: an escrow funded at closing; a letter of credit; a guarantee from a creditworthy parent; a negative covenant restricting distributions or additional indebtedness; or a security interest in the acquired assets, which buyers with lenders will refuse. At minimum, get the parent guarantee.

Set-off. Buyers want the right to set off indemnification claims against earnout payments. Sellers want set-off limited to finally determined claims, or excluded entirely. The middle position: set-off permitted for claims that have been finally determined, and for pending good-faith claims only to the extent the disputed amount is placed in escrow rather than retained.

Seller representative. Where there are many sellers, a representative must be appointed with authority to receive statements, deliver objections, negotiate, engage professionals, and settle, funded by a holdback for expenses, with exculpation and indemnification from the sellers. A missing or unfunded representative is the reason many multi-seller earnout objections are never delivered.

Earnouts in the securities law frame

An earnout right can be a security. Where the earnout is payable to a diffuse group of former stockholders, is transferable, and depends on the entrepreneurial efforts of the buyer, it has the characteristics the Howey framework identifies — an investment of money in a common enterprise with profits derived from the efforts of others.

The practical consequences. Registration or an exemption must be available for the issuance of the earnout right; the disclosure delivered to selling stockholders in connection with the merger is subject to the antifraud provisions of 15 U.S.C. § 78j and Rule 10b-5; and the earnout right, if transferable, may need transfer restrictions to avoid creating an unregistered trading market.

The usual mitigations. Make the earnout right expressly non-transferable except by operation of law; deliver it only to accredited investors or to a limited number of holders; and prepare the disclosure with the same care as an offering document, because a seller who is disappointed by an earnout will read the deal disclosure looking for something actionable.

When the fight starts: litigating an earnout dispute

Characterize the claim correctly at the outset. There are three distinct claims and they proceed differently.

One: a breach of the express operating covenants. The strongest seller claim when the covenants exist. Proof is documentary — the budget, the headcount, the marketing spend, the pricing decisions — and damages are the earnout that would have been earned, which requires an expert model of the counterfactual.

Two: a breach of the accounting provisions. Whether the statement was prepared consistently with the agreed hierarchy and the sample calculation. Usually routed to the independent accountant, and usually resolved there.

Three: breach of the implied covenant. The residual claim where the express terms do not reach the conduct. Under Nemec and Winshall, it is a narrow claim, unavailable to contradict an express term, and it requires the seller to identify a gap the parties would have filled had they anticipated the issue. It is not a claim about fairness.

Preservation matters early. The objection deadline is a contractual limitation and it is enforced. So is the specificity requirement. A seller representative's first three tasks on receiving an earnout statement are: calendar the deadline; demand access in writing; and engage an accountant.

Discovery in an earnout case is mostly the buyer's internal documents — integration plans, budget submissions, sales compensation plans, management reporting packages, and the emails discussing how the acquired business fits the buyer's broader plan. Buyers should assume this and should manage their internal communications accordingly; an integration email observing that a decision "helps us on the earnout" is worth more to the seller than any expert report.

Damages theory. The seller's model must show what the metric would have been but for the breach. Buyers attack causation — the target would have missed anyway, for market reasons — and attack the counterfactual as speculative. Sellers who negotiated an acceleration provision skip this entire fight, which is the strongest argument for negotiating one.

Whether to use an earnout at all

The honest answer is that an earnout is often a way of not resolving a disagreement, and that it converts a valuation dispute into a contract dispute that will be resolved later, at greater cost, by people with less information.

When an earnout genuinely helps. When the contingency is binary, verifiable, and outside the buyer's control — a regulatory approval, a court decision, a patent issuance, the renewal of a named contract by a third party. These earnouts work, they rarely litigate, and they solve exactly the problem they were designed for.

When it usually works. When the target will be operated as a standalone unit by the same management for the earnout period, with a real firewall from the buyer's other operations, and the metric is revenue rather than a bottom-line figure.

When it usually fails. When the target will be integrated immediately, when the metric is EBITDA or net income, when the seller's management leaves at closing, and when the gap being bridged is a genuine disagreement about the quality of the business rather than about a specific identifiable contingency.

The alternatives worth considering first. A lower fixed price. A seller note with a fixed schedule. Rollover equity in the buyer or in a holding vehicle, which aligns the parties permanently rather than for three years. A holdback against specified risks. Representation and warranty insurance, which sometimes closes a gap that is really about risk rather than about value.

And a candid conversation with the client. A seller taking an earnout should be told plainly: you are accepting a claim against a company you will not control, measured by numbers you will not prepare, in a business you will not run. Price that. Many sellers, told this clearly, take less cash at closing instead — and are better off.

Multi-seller and representative mechanics

Where the sellers are numerous — a venture-backed company, a family business with many branches, a company with broad option participation — the earnout is administered through a representative, and the mechanics deserve attention they rarely get.

Appointment. By the merger agreement and by the letters of transmittal, with an irrevocable power of attorney binding on successors and assigns. The appointment should survive the seller's death, dissolution, or transfer of the earnout right.

Authority. To receive statements and notices; to deliver objections; to negotiate and settle; to engage accountants and counsel at the sellers' expense; to bind all sellers by its actions; and to allocate and distribute payments.

Funding. An expense fund withheld at closing — commonly a fixed dollar amount rather than a percentage — held by the representative, replenishable from earnout proceeds, and returned to the sellers on termination. An unfunded representative will not object, because objecting costs money it does not have.

Exculpation and indemnity. The representative should be exculpated for anything short of gross negligence or willful misconduct and indemnified by the sellers, or no competent person will serve. Professional representative firms exist for exactly this reason and are worth their fee in any deal with more than a handful of sellers.

Allocation among sellers. The waterfall governing how earnout proceeds are shared — preferences, participation, option holders, and the treatment of holders who did not sign the letter of transmittal — should be computed and attached as a spreadsheet at closing, not derived later. Allocation disputes among sellers are as common as disputes with the buyer and are far more bitter.

Escrow interaction and the order of operations

An acquisition with an earnout typically also has an indemnity escrow, an adjustment escrow, and a representative expense fund. The order in which claims hit these accounts matters and should be specified.

A workable order. Adjustment claims are satisfied first from the adjustment escrow, then from the earnout, then directly from the sellers only if the agreement provides recourse. Indemnity claims are satisfied first from insurance if representation and warranty insurance is in place, then from the indemnity escrow, then from the earnout by set-off only if expressly permitted, then from the sellers to the extent of any surviving recourse.

The set-off question deserves its own sentence. A buyer with an unrestricted right to set off against the earnout holds a self-help remedy that a seller can only undo by suing. Sellers should insist that set-off be limited to finally determined claims, or that disputed amounts be escrowed rather than retained. Buyers should recognize that an aggressive set-off is the single most reliable way to convert a manageable disagreement into litigation.

Release timing. The adjustment escrow releases on finalization of the closing statement. The indemnity escrow releases on the survival date, less amounts reserved for pending claims. The representative expense fund releases when the last obligation is satisfied. Each release should be automatic on a date, with a mechanism requiring a written claim notice to hold back — not dependent on the buyer's affirmative instruction, which a buyer in a dispute has no incentive to give.

Common drafting failures

No sample calculation. The most consequential omission in the field. One exhibit prevents most disputes.

"In accordance with GAAP" with no hierarchy. Invites a restatement.

An undefined "Business." Post-integration, the earnout metric has no referent.

An efforts clause with no floors. Buys the seller a lawsuit, not a remedy.

Intent-based covenants. After Lazard, a covenant against actions "intended to reduce the earnout" is very hard for a seller to enforce.

Overhead allocation left open. Buyers will allocate; the only question is how much, and an uncapped allocation can eliminate the earnout entirely without anyone acting in bad faith.

A single dispute mechanism for accounting and breach. Produces a threshold fight about the accountant's jurisdiction.

No acceleration on sale. The buyer sells the business in year two, and the seller's earnout evaporates with no breach of anything.

No security and no guarantee. The earnout obligor is a shell subsidiary and the seller is an unsecured creditor of it.

No seller representative, or an unfunded one. Nobody has authority to object, and nobody will pay the accountant.

Deferred revenue treated inconsistently between the target calculation and the closing statement. This one alone accounts for a remarkable share of working capital disputes.

Practice pointers

Build the sample calculation from the target's actual trial balance, sign it as an exhibit, and require the closing statement to be prepared the same way.

State the accounting hierarchy in three tiers — agreed policies exhibit, then historical practice, then GAAP — and add the anti-restatement sentence.

Define the earnout metric by product or contract, not by legal entity or business unit, because entities and business units get reorganized.

Cap the overhead allocation in dollars, escalating on a stated basis.

Replace efforts language with covenants and floors, and back them with acceleration.

Carve breach claims out of the accountant's jurisdiction and route them to litigation or arbitration expressly.

Decide whether the accountant is an expert or an arbitrator, and say so — the answer determines whether 9 U.S.C. §§ 9 and 10 supply the review framework.

Use baseball resolution with proportional fee allocation. It disciplines both sides' positions before the submission is written.

Fund an adjustment escrow separate from the indemnity escrow.

Get the tax treatment right at signing — installment method under § 453, imputed interest under §§ 483 and 1274, and a clean separation between purchase price and employment compensation.

Tax consequences of deferred consideration

Installment sale treatment. Under 26 U.S.C. § 453, a disposition where at least one payment is received after the close of the taxable year is generally reported on the installment method, with gain recognized as payments are received. Earnouts are a paradigm case, and the mechanics — computing a gross profit ratio when the total contract price is contingent — follow special rules for contingent payment sales that spread basis over the maximum payment period.

Electing out. A seller may elect out of installment treatment and recognize the full gain at closing, valuing the contingent right. Sometimes advantageous — a seller expecting rate increases, or one who wants to close the tax year — and it requires valuing something that by definition has no market.

Imputed interest. Deferred payments carry interest whether or not the contract says so. 26 U.S.C. § 483 treats part of a deferred payment as interest where the contract does not provide adequate stated interest, and 26 U.S.C. § 1274 governs issue price determinations for debt instruments issued for property. The consequence for the seller is that a portion of what feels like purchase price is taxed as ordinary interest income, and the consequence for the drafter is that the agreement should address whether the earnout bears stated interest and at what rate.

Character. Earnout consideration generally retains the character of the underlying sale — capital gain for a stock sale — except for the imputed interest component. Except where the earnout is structured or characterized as compensation for post-closing services, in which case it is ordinary income subject to employment taxes. This is a real risk when the earnout is payable only to sellers who remain employed, or is forfeited on termination. Sellers who are also employees should have the compensation question addressed expressly, and the agreement should separate purchase price from employment compensation deliberately.

Buyer's side. For accounting purposes, contingent consideration in a business combination is recognized at fair value at acquisition and remeasured through earnings, which produces earnings volatility the buyer's CFO will care about even if the lawyers do not.
