Earn‑outs in Serbia 2026: How to Structure Contingent Consideration in M&A Deals

Earn-outs in Serbia have become a central tool for bridging valuation gaps in mid-market and cross-border M&A, and their use has grown steadily heading into 2026. Against a background of amendments to the Companies Act and shifts in the tax and investment-incentive landscape, buyers and sellers increasingly rely on contingent consideration to allocate risk over post-closing performance rather than agreeing on a single fixed price at signing. This guide sets out, in practical terms, when an earn-out makes commercial sense, how to draft enforceable measurement and payment mechanics, how the arrangement is likely to be taxed, and how disputes can be avoided or resolved under Serbian law.

It is written for deal principals and their advisers who need concrete drafting guidance, not high-level commentary.

Who this is for: Buyers, sellers, M&A lawyers, in-house counsel, tax advisers and investors doing deals in Serbia in 2026. It covers when to use an earn-out, how to draft enforceable mechanics, tax treatment, dispute-risk management, and a ready-to-adapt model clause and negotiation checklist.

Executive summary: earn-outs in Serbia at a glance

Contingent consideration allows the parties to defer part of the purchase price and tie it to the target’s future performance. The mechanism is powerful, but it is only as good as the drafting behind it. The key takeaways are as follows:

• Use an earn-out to bridge a genuine valuation gap. Earn-outs work best where buyer and seller disagree on future performance and where that performance is measurable and materially within the control of parties who remain involved after closing.
• Precision in measurement is everything. The most litigated aspect of any earn-out is how the metric is defined, calculated and verified. Vague definitions, undefined accounting policies and open-ended discretion invite dispute.
• Tax timing and structure must be modelled early. Whether the transaction is a share sale or an asset sale, and when contingent amounts are recognised, will affect the net outcome for the seller and should be confirmed with local tax advice.
• Enforcement is realistic but requires forethought. Serbian courts and arbitration are both available; arbitral awards benefit from recognised international enforcement frameworks, but drafting must anticipate evidence, audit and expert-determination mechanics.

Each of these points is developed below, with model language and a worked numerical example at the end.

Why earn-outs are prominent in Serbia in 2026

Several forces are converging to make earn-outs in Serbia more prevalent than they were only a few years ago. Valuation uncertainty following volatile trading conditions has widened the gap between seller expectations and buyer willingness to pay upfront. At the same time, an active inbound investment climate, supported by Serbia’s ongoing regulatory alignment in the EU accession context, has increased deal volume in sectors where future performance is inherently uncertain, such as technology, renewables and services. Where the parties cannot agree on a fixed valuation, an earn-out lets them proceed on a shared, performance-linked basis rather than walking away from the deal.

For deal teams already tracking the recent corporate reforms discussed in Serbia corporate law changes 2026, contingent consideration is a natural extension of the same risk-allocation logic.

Companies Act and disclosure changes affecting post-closing obligations

The Companies Act (Zakon o privrednim društvima), as amended and published in the Official Gazette of the Republic of Serbia, governs the corporate framework within which earn-outs operate. This matters because an earn-out typically requires the seller, or the departing management, to retain influence over the target after closing, and because the buyer will need reliable access to financial information to calculate the contingent payment. Directors’ duties, disclosure requirements and the treatment of related-party transactions all shape how much post-closing control and information a seller can lawfully retain and how buyers must conduct the business during the earn-out period.

Parties structuring earn-outs in Serbia should confirm the current statutory position on directors’ duties and reporting obligations directly against the current Official Gazette text rather than relying on older summaries.

Tax and incentive considerations and investor preferences

Changes in the tax and investment-incentive regime, reflected in Ministry of Finance policy and Tax Administration guidance, influence how buyers and sellers prefer to structure consideration. Where incentives favour certain investment structures, or where the timing of income recognition affects the seller’s after-tax return, the earn-out becomes a lever to optimise both risk and tax outcome. This is a technical area: the correct treatment depends on whether the deal is a share or asset sale and on precisely how the contingent payment is characterised. Investors increasingly ask their advisers to model the tax consequences of contingent consideration Serbia arrangements at the term-sheet stage, before mechanics are locked in.

When to use an earn-out, commercial decision checklist

Before drafting, the parties should be honest about whether an earn-out is the right instrument at all. An earn-out is appropriate where three conditions are broadly met: there is a real valuation gap driven by genuine uncertainty about future performance; that performance can be measured objectively over a defined period; and the people who drive performance, often the selling founders, will remain engaged after closing. Earn-outs are also valuable as a retention tool, aligning departing owners with the buyer’s success for a transitional period. Where these conditions are absent, an earn-out can create more problems than it solves.

Alternatives to earn-outs and when they fit

An earn-out is not the only way to bridge a gap or manage post-closing risk. A simple completion accounts or working-capital adjustment addresses valuation drift between signing and closing without linking price to future performance. An escrow or holdback retains part of the price to secure warranty and indemnity claims. Deferred consideration paid on fixed dates, without a performance condition, gives the seller certainty while easing the buyer’s cash requirements. Each of these is simpler to administer and less prone to dispute than an earn-out, and one of them may be a better fit where the valuation gap is modest or where the seller is exiting entirely.

Red flags, when to avoid an earn-out

Caution is warranted where the seller will have no continuing role and therefore no ability to influence the metric; where the buyer intends significant integration, restructuring or reinvestment that will distort standalone performance; or where the chosen metric is easily manipulated by the party who controls it. Highly subjective milestones, short earn-out periods that magnify timing effects, and metrics dependent on group-level allocations all raise the dispute risk. If any of these red flags are present, the parties should reconsider the structure or invest heavily in protective drafting.

Types of earn-outs and payment mechanics

Earn-outs fall into two broad families: those keyed to a financial metric and those keyed to operational milestones. The choice drives everything that follows, measurement, verification, timing and dispute risk. Within each family, the parties can layer single or multiple tranches, apply a cap on the maximum payable, set a floor or threshold below which nothing is due, and use a collar to smooth results around a target. Adjustments can be positive (rewarding outperformance) or, more rarely, negative (clawing back overpayment where a prior tranche was based on results that later reversed).

Financial-metric (EBIT / EBITDA / revenue) earn-outs, calculation mechanics

Financial-metric earn-outs tie the payment to a defined accounting figure, most commonly revenue, EBIT or EBITDA, measured over one or more periods after closing. Their appeal is objectivity: the figure is derived from the target’s accounts and can be verified by an accountant. The mechanics that must be nailed down include the precise definition of the metric, the accounting policies used to derive it, the measurement period, any normalisation of one-off items, and the formula converting performance into money (for example, a multiple of the amount by which EBITDA exceeds a baseline, subject to a cap). Because the figure flows from the accounts, financial-metric earn-outs are generally easier to quantify and, if disputed, easier to resolve through expert determination.

Milestone and KPI earn-outs, operational milestones, measurement and subjectivity

Milestone earn-outs pay on the occurrence of discrete events, securing a regulatory approval, signing a named customer, launching a product, or retaining a specified headcount. They suit deals where value is driven by binary outcomes rather than by a smooth financial curve. The trade-off is subjectivity: whether a milestone has truly been “achieved” can be contentious, particularly where the milestone is partly qualitative. To reduce that risk, each milestone should be defined with objective, evidence-based acceptance criteria, a clear deadline, and a designated method of proof. The more precise the definition, the lower the enforcement risk.

Key drafting elements, definitions, measurement and calculation

The drafting of earn-outs in Serbia lives or dies on definitional precision. This is where experienced counsel earn their fee, because ambiguity in the definitions section is where most disputes originate. The four pillars are the performance metric, the calculation mechanics and payment timing, the accounting principles, and the audit and information rights that make verification possible.

Defining the performance metric

If the metric is a financial figure, define it exhaustively. “Adjusted EBITDA,” for example, should be defined by reference to a stated starting point in the accounts and an itemised list of add-backs and deductions, one-off restructuring costs, non-recurring legal fees, related-party charges, management fees imposed by the buyer’s group, and any accounting-policy changes introduced after closing. The definition should specify the treatment of items the buyer might otherwise use to depress the figure, such as intra-group cost allocations or discretionary reinvestment. Where the metric is a milestone, define the acceptance criteria and the evidence that will establish achievement.

Calculation mechanics and timing of payments

Set out the measurement period or periods, the date on which the calculation is prepared, who prepares it (usually the buyer, subject to the seller’s review), and the deadline for delivering the earn-out statement. Specify the currency of payment and any conversion mechanism if the metric is measured in one currency and paid in another, together with rounding conventions. Where the earn-out spans multiple tranches, state whether a shortfall in one period can be recovered in a later period (a “catch-up”) and whether tranches are independent. Finally, fix the payment date by reference to the finalisation of the statement and specify the consequences of late payment, including default interest.

Accounting principles and normalisation

State expressly which accounting framework governs the calculation and, critically, how conflicts between frameworks are resolved. A common and effective hierarchy provides that the earn-out accounts are prepared, first, in accordance with specified policies set out in a schedule; then consistently with the accounting policies used in the target’s most recent audited accounts; and only then in accordance with the applicable general framework. Normalisation adjustments, removing distortions caused by the transaction itself or by the buyer’s post-closing decisions, should be pre-agreed and listed. This prevents the buyer from steering the metric through legitimate but adverse accounting choices.

Audit, information rights and the accountants’ role

An earn-out is unenforceable in practice if the seller cannot see the numbers. The agreement should grant the seller reasonable access to the books, records and personnel needed to verify the earn-out statement, along with a defined window to raise objections. Where the parties cannot agree, the contract should refer the dispute to an independent accountant acting as an expert (not an arbitrator), whose determination on accounting questions is final and binding. This mechanism resolves technical measurement disputes quickly and keeps them out of full-blown litigation.

Governance, warranties, covenants and seller protections

Once the metric is defined, the parties must protect its integrity during the earn-out period. Because the buyer controls the business after closing, the seller needs contractual assurance that the buyer will not, whether deliberately or through ordinary restructuring, undermine the metric on which payment depends. This is achieved through operating covenants and a carefully balanced package of seller protections.

Preserving target performance, covenants and budgets

The buyer typically covenants to operate the target in the ordinary course during the earn-out period, to maintain adequate resources and staffing, not to divert revenue or opportunities to other group companies, and not to impose intra-group charges that reduce the metric. An agreed budget or business plan can anchor these obligations. Restrictive covenants may bind the seller too, preventing the departing owners from competing or soliciting customers in ways that would harm the very performance they are being paid on. The covenant package should be proportionate: overly restrictive covenants can hamper legitimate integration and generate their own disputes.

Seller protections, caps, floors and compensation for breach

Sellers should negotiate a clear cap so the maximum exposure is known, and, where appropriate, a floor or threshold that guarantees a minimum payment once a base level of performance is met. Crucially, the agreement should provide a remedy where the buyer breaches its operating covenants, for example, a “deemed achievement” clause treating the metric as satisfied to the extent the breach caused the shortfall, or a right to damages. A holdback or escrow can secure the buyer’s own warranty claims, while a clawback can recover contingent amounts paid on results later found to be misstated. Balancing these tools is the core of the earn-out negotiation.

Tax treatment of earn-outs in Serbia, practical notes

The tax treatment of earn-outs in Serbia depends on the structure of the transaction and the characterisation of the contingent payment, and it should be confirmed with the Tax Administration and current Ministry of Finance guidance before terms are agreed. The general principle is that contingent consideration forms part of the sale price, but the timing of recognition and the applicable rate can differ markedly between a share sale and an asset sale. Because the net-of-tax outcome can swing significantly, tax modelling belongs at the term-sheet stage, not the drafting stage.

Share purchase versus asset purchase tax differences

In a share sale, the seller disposes of shares and the consideration, including any earn-out amounts subsequently received, is generally treated as proceeds of that disposal. In an asset sale, the target company sells its assets, the tax consequences fall at the company level, and the profile of gains, allowances and recoverable input positions differs. The two routes can produce very different results for the same economic deal, which is one reason the choice of structure is often driven as much by tax as by legal or commercial considerations. Sellers should obtain a written tax opinion confirming how the contingent element will be treated under the chosen structure.

Withholding, VAT and timing of recognition

Where the seller is a non-resident, withholding tax may apply to certain payments, and the availability of double-tax-treaty relief should be checked before closing. VAT treatment depends on whether the transaction is a share transfer or an asset transfer and on how the assets are characterised. Timing is the recurring theme: because earn-out amounts are, by definition, uncertain at closing and paid later, the point at which income is recognised, and therefore taxed, needs to be pinned down against Tax Administration guidance. Contemporaneous documentation supporting the characterisation and timing of each payment is the seller’s best protection in any subsequent review.

Enforcement, disputes and dispute-avoidance for earn-outs in Serbia

Even a well-drafted earn-out can end in dispute, so the enforcement architecture must be built into the contract from the outset. Enforcement of earn-outs in Serbia is realistic through both the courts and arbitration, but each route has distinct advantages, and the drafting should reflect a deliberate choice rather than a boilerplate default. The most effective agreements combine a tiered dispute mechanism, expert determination for accounting questions, negotiation for commercial ones, and a final binding forum for everything else, with clear remedies.

Arbitration versus litigation, practical considerations

Arbitration is frequently preferred for cross-border earn-outs because it offers confidentiality, a neutral forum, the ability to appoint arbitrators with relevant commercial or accounting expertise, and, importantly, broad international enforceability of awards under the New York Convention, to which Serbia is a party. The Permanent Arbitration at the Chamber of Commerce and Industry of Serbia provides established arbitration infrastructure and rules for commercial disputes. Litigation before the Serbian courts, by contrast, may be more appropriate for purely domestic deals or where interim court remedies are needed quickly. The clause should specify the seat, language, governing rules and number of arbitrators, and should sit consistently with the expert-determination mechanism so the two do not overlap or conflict.

Evidence, audits and expert determinations

Most earn-out disputes are, at heart, disputes about numbers. Building strong evidence and audit rights into the contract dramatically reduces both the likelihood and the cost of conflict. The independent-expert mechanism described earlier resolves technical accounting questions efficiently and should be drafted to bind the parties on those questions, leaving only genuine legal disputes, such as whether a covenant was breached, for the arbitral or judicial forum. Clear record-keeping obligations and access rights ensure that, if a dispute does arise, the evidence needed to resolve it is available.

Remedies and enforcement steps in Serbia

Available remedies include monetary damages, contractual interest on late payment, set-off against amounts the buyer owes, and, in appropriate cases, orders compelling performance of specific obligations such as delivery of the earn-out statement. Once an award or judgment is obtained, it is enforced through the applicable Serbian enforcement procedures, generally administered through public enforcement agents (javni izvršitelji); parties should also be mindful of the limitation periods for contractual claims under the Law on Obligations and ensure claims are brought in time. Confirming the current limitation position and enforcement mechanics with local counsel is an essential final step.

Model clause and worked example for earn-outs in Serbia

The following is illustrative only and must be adapted and reviewed by qualified local counsel before use in any transaction.

Model clause (annotated)

Template, for illustrative purposes only. “Subject to the terms of this Agreement, the Buyer shall pay to the Seller additional consideration (the Earn-Out Payment) calculated as [multiple] × the amount (if any) by which Adjusted EBITDA of the Target for the Earn-Out Period exceeds the Baseline of [amount], subject to a maximum aggregate Earn-Out Payment of [cap]. Adjusted EBITDA shall be determined in accordance with the accounting policies set out in Schedule [X], applied consistently with the Target’s most recent audited accounts. The Buyer shall deliver the Earn-Out Statement within [number] days of the end of the Earn-Out Period. The Seller shall have [number] days to review the Earn-Out Statement and access to the relevant books and records.

Any dispute as to the accounting determination shall be referred to an Independent Expert whose decision shall be final and binding. During the Earn-Out Period the Buyer shall operate the Target in the ordinary course and shall not take any action with the purpose of artificially reducing Adjusted EBITDA.

Annotations: define every capitalised term precisely; list add-backs and deductions in the schedule; align the expert-determination clause with the main dispute-resolution clause; and add a “deemed achievement” remedy for covenant breach.

Worked numeric example

Assume a baseline Adjusted EBITDA of €2,000,000, an earn-out multiple of 4×, and a cap of €3,000,000. If the Target achieves Adjusted EBITDA of €2,500,000 in the Earn-Out Period, the excess over baseline is €500,000. Applying the 4× multiple yields €2,000,000, which is below the €3,000,000 cap and therefore payable in full. Had the Target achieved €3,000,000, the excess would be €1,000,000, producing €4,000,000 on the multiple, but the cap limits the payment to €3,000,000. This illustrates how the multiple, baseline and cap interact to define the seller’s realistic upside.

Practical negotiation checklist and templates

The following compact checklist helps both sides pressure-test an earn-out before signing:

1. Confirm the valuation gap is genuine and that an earn-out, rather than escrow or deferred consideration, is the right tool.
2. Choose the metric (financial versus milestone) and confirm it is measurable and hard to manipulate.
3. Define the metric exhaustively, including add-backs, deductions and accounting policies.
4. Fix the measurement period, calculation date, statement deadline and payment date.
5. Agree the multiple, baseline, cap and any floor or collar.
6. Draft operating covenants protecting the metric and a remedy for their breach.
7. Secure audit and information rights and a defined objection window.
8. Include an independent-expert mechanism for accounting disputes.
9. Model the tax outcome for the chosen structure and obtain a written tax opinion.
10. Select and align the dispute-resolution forum, and confirm enforcement and limitation mechanics with local counsel.

Conclusion and next steps

Earn-outs in Serbia offer a proven way to close valuation gaps and align sellers with post-closing performance, and their relevance remains significant against the backdrop of the 2026 corporate and tax landscape. The difference between a smooth earn-out and a costly dispute lies almost entirely in the drafting: precise metric definitions, robust accounting policies, protective covenants, verified information rights and a coherent dispute-resolution architecture. Because the tax and enforcement positions turn on structure and current guidance, every arrangement should be validated against primary Serbian sources and confirmed with qualified local advisers before signing.
