Earn‑outs in UAE M&A 2026, How to Draft, Structure and Enforce Performance‑based Consideration

Earn‑outs in UAE M&A transactions have moved from a niche pricing mechanism to a central point of negotiation, and, increasingly, of post‑completion litigation. The convergence of two forces makes 2026 a pivotal year for practitioners: a pronounced spike in earnout disputes driven by valuation uncertainty across the Gulf, and the entry into force of the new UAE Civil Transactions Law (CTL 2025), which recalibrates how courts interpret contractual obligations, assess remedies and weigh evidence. For in‑house counsel, PE sponsors, founders and deal lawyers advising on UAE acquisitions, the practical question is no longer whether to use an earn‑out but how to draft one that survives enforcement.

This guide provides a jurisdiction‑specific playbook covering model clause language, KPI governance, accounting treatment and the full spectrum of enforcement pathways available in onshore UAE courts, the DIFC and the ADGM.

Quick answer: Earn‑outs are enforceable in the UAE provided the performance metrics, calculation methodology and payment mechanics are drafted with sufficient precision. Under the new CTL, courts will apply modernised rules of contractual interpretation and evidence, making clear, self‑contained earn‑out clauses more important than ever.

What Is an Earn‑out and When to Use One in UAE Deals

An earn‑out is a contractual mechanism in a share purchase agreement (SPA) under which part of the purchase price is contingent on the target business achieving specified performance thresholds after completion. The buyer pays an upfront amount at closing, and additional consideration, the earn‑out, is released only if agreed targets are met within a defined measurement period. Earn‑outs are used most frequently when the buyer and seller disagree on valuation, when the target’s future cash flows depend heavily on the seller’s continued involvement, or when macroeconomic conditions make fixed pricing unreliable.

Earn‑out Types

In the UAE market, earn‑outs typically fall into three categories. Financial KPI‑based earn‑outs tie payments to revenue, EBITDA, net profit or gross margin targets, these dominate mid‑market SPAs. Operational milestone earn‑outs link consideration to non‑financial achievements such as regulatory licence approvals, customer contract renewals or product launch dates; these are common in technology and healthcare transactions. Hybrid structures combine financial and operational triggers, often with tiered payment bands and cap/collar mechanisms to allocate risk between the parties.

Alternatives to Earn‑outs

Practitioners should consider whether an earn‑out is the right tool or whether a simpler post-completion adjustment in the UAE context would suffice. Alternatives include deferred consideration (a fixed sum paid on a future date regardless of performance), escrow or holdback mechanisms (where funds are withheld to secure warranty claims), and contingent value rights (CVRs), tradeable instruments occasionally used in larger transactions. Each alternative carries different risk profiles; earn‑outs remain the preferred mechanism where genuine valuation uncertainty exists and the seller retains operational influence post‑closing.

Why Earn‑outs Are Rising, 2024–2026 Earnout Disputes and UAE Law Reforms

The 2026 Dispute Spike

Industry observers report a material increase in earnout disputes across the Gulf during 2024–2026, driven by three recurring causes. First, ambiguous KPI definitions, particularly around adjusted EBITDA, have generated accounting disagreements that neither party can resolve without external adjudication. Second, buyers’ post‑completion management decisions (restructuring, cost‑cutting, reallocation of revenue streams) have been challenged by sellers alleging deliberate suppression of earn‑out metrics. Third, inadequate data‑access provisions have left sellers unable to verify calculations, triggering formal disputes within months of closing. Practitioner commentary from UAE‑based firms confirms that these patterns mirror global trends but are amplified in the Emirates by rapid deal flow and the prevalence of founder‑led targets where earn‑outs substitute for full price certainty.

The 2025 UAE Civil Transactions Law, Implications for Drafting Earn‑outs in UAE SPAs

The new UAE Civil Transactions Law, enacted in 2025 and effective from mid‑2026, introduces significant changes to how contracts are interpreted and disputes resolved. As analysed by Tamimi & Co, the CTL modernises the rules governing contractual interpretation, placing greater emphasis on the written terms of agreements and updating the evidential framework for commercial disputes. K&L Gates has noted that the CTL also revises the transitional provisions applicable to contracts entered into before its effective date, meaning that SPAs signed in late 2025 or early 2026 may straddle two regimes.

For earn‑out clauses specifically, the likely practical effects include a stronger judicial focus on the express wording of the clause (reducing scope for implied good‑faith arguments to override clear drafting), updated rules on the admissibility and weight of expert evidence (critical where accounting disputes arise), and revised remedies provisions that may affect the calculation of damages for earn‑out non‑payment. Early indications suggest that counsel should treat the CTL as an opportunity: well‑drafted earn‑out clauses will benefit from more predictable enforcement, while loosely worded provisions face heightened risk of adverse interpretation.

Drafting an Enforceable Earnout Clause for UAE SPAs, Model Clause and Annotated Drafting Notes

The single most effective way to prevent an earn‑out dispute is rigorous front‑end drafting. The model clause below is designed for inclusion in a UAE‑governed share purchase agreement and should be adapted to the specific transaction. It addresses the core elements that UAE courts and arbitral tribunals will scrutinise when assessing enforceability.

Model Earn‑out Clause

The following is an illustrative earn‑out clause for a UAE SPA. It is provided for guidance and must be tailored to each transaction by qualified legal counsel.

Clause [●], Earn‑Out Consideration

1. Definitions. “Earn‑Out Period” means the [twelve (12) / twenty‑four (24)]‑month period commencing on the Completion Date. “Earn‑Out KPI” means [Adjusted EBITDA / Net Revenue / [specify]] of the Target, calculated in accordance with Clause [●].3. “Earn‑Out Amount” means the amount (if any) payable by the Buyer to the Seller(s) pursuant to Clause [●].2, subject to the Earn‑Out Cap.

2. Calculation. If the Earn‑Out KPI for the Earn‑Out Period equals or exceeds [AED ●] (the “Threshold”), the Buyer shall pay to the Seller(s) an amount equal to [●]% of the amount by which the Earn‑Out KPI exceeds the Threshold, up to a maximum of AED [●] (the “Earn‑Out Cap”). If the Earn‑Out KPI is below the Threshold, no Earn‑Out Amount shall be payable.

3. Accounting Rules. The Earn‑Out KPI shall be determined in accordance with IFRS as applied consistently with the Target’s audited financial statements for the financial year ended [●], subject to the normalisation adjustments set out in Schedule [●] (Normalisation Adjustments). For the avoidance of doubt, the following items shall be excluded from the calculation: [extraordinary items / related‑party transactions not on arm’s‑length terms / restructuring costs initiated by the Buyer / [specify]].

4. Conduct Covenants. During the Earn‑Out Period, the Buyer shall (a) operate the Target in the ordinary course of business consistent with past practice; (b) not, without the prior written consent of the Seller Representative, make any material change to the Target’s accounting policies, revenue recognition practices or organisational structure that would materially and adversely affect the Earn‑Out KPI; and (c) provide the Seller Representative with [monthly / quarterly] management accounts within [15 / 30] Business Days of the end of each [month / quarter].

5. Earn‑Out Statement and Payment. Within [60] Business Days after the end of the Earn‑Out Period, the Buyer shall deliver to the Seller Representative a statement (the “Earn‑Out Statement”) setting out the Buyer’s calculation of the Earn‑Out KPI and the Earn‑Out Amount, together with reasonable supporting documentation. Payment of any Earn‑Out Amount shall be made within [15] Business Days of the Earn‑Out Statement becoming final and binding pursuant to Clause [●].6.

6. Dispute Resolution. If the Seller Representative disputes the Earn‑Out Statement, the dispute shall first be referred to an independent accounting expert (the “Expert”) appointed in accordance with Schedule [●]. The Expert’s determination shall be final and binding on the parties in the absence of manifest error. Any dispute that is not a Calculation Dispute (as defined) shall be resolved by [arbitration under the rules of the [DIAC / ICC / LCIA] seated in [Dubai / Abu Dhabi / DIFC / ADGM]].

Annotated Drafting Notes

Note 1, Earn‑Out Period length. The standard market range in UAE deals is 12 to 24 months. Longer periods increase the seller’s exposure to buyer management decisions; shorter periods may not capture the full cycle needed to measure the target’s performance reliably. Counsel should align the period with the target’s financial reporting cycle.

Note 2, KPI selection. Choose the metric that best reflects the value driver the parties disagree on. Revenue is harder to manipulate but ignores profitability; EBITDA captures operational performance but requires extensive normalisation. Where possible, specify the exact line items from the target’s chart of accounts that feed into the calculation.

Note 3, Normalisation schedule. This schedule is often the most heavily negotiated annex. Draft it as an exhaustive, closed list rather than a set of principles. Include worked examples for contentious items such as management fees, intercompany charges and one‑off costs. Ambiguity here is the single largest source of earnout disputes in 2026.

Note 4, Conduct covenants. The scope of the buyer’s ordinary‑course obligation should be calibrated precisely. Overly broad covenants restrict the buyer’s ability to integrate the target; overly narrow provisions leave the seller vulnerable. Consider a materiality threshold (e.g., changes that would reduce the Earn‑Out KPI by more than a specified percentage) and enumerate specific prohibited actions.

Note 5, Payment mechanics. Specify the currency (AED or USD), the bank account, applicable withholding and whether interest accrues on late payment. Under UAE corporate tax rules introduced in 2023, consider whether the earn‑out payment triggers a taxable event for either party and draft accordingly.

Note 6, Expert determination vs arbitration. The hybrid model in the clause above, expert determination for pure calculation disputes, arbitration for all other disputes, is the approach most commonly adopted in the UAE. It is critical to define “Calculation Dispute” narrowly to avoid jurisdictional overlap.

Practical Drafting Checklist for Earn‑outs in UAE M&A

Before circulating the SPA, counsel should confirm that the earn‑out clause addresses every item on the following checklist:

• KPI defined by reference to specific financial line items. Avoid generic terms such as “profits”, use the target’s chart of accounts and IFRS standards.
• Measurement period start and end dates stated precisely. Confirm alignment with the target’s financial year‑end.
• Accounting basis specified. State IFRS (or other applicable standards) and identify the reference period for consistency.
• Normalisation adjustments listed exhaustively in a schedule, with worked examples where possible.
• Cap, floor and collar mechanisms stated in absolute AED/USD amounts.
• Conduct covenants tailored to the target’s business. Include a materiality qualifier and a list of buyer‑restricted actions.
• Reporting cadence and content specified. Define exactly which management accounts the seller is entitled to receive and by when.
• Access to books and records. Grant the seller (or its auditor) a right of inspection, with reasonable notice and confidentiality safeguards.
• Earn‑out statement delivery deadline and content requirements defined.
• Dispute resolution mechanism identified, expert determination for calculation disputes; arbitration or court proceedings for legal disputes.
• Expert appointment mechanism specified, including the appointing body, qualifications, timeline and cost allocation.
• Governing law and jurisdiction stated expressly. Confirm whether onshore UAE law, DIFC law or ADGM law applies, and ensure consistency with the SPA’s general governing‑law clause.

Measurement, Governance and Earn‑out KPIs in UAE Transactions

Choosing Objective KPIs vs Subjective Performance Measures

Objective, financially auditable KPIs are strongly preferred in the UAE because they reduce the scope for post‑completion arguments and simplify expert determination. Subjective measures, such as “customer satisfaction” or “market reputation”, are difficult to enforce and should be avoided unless supported by a precise, contractually defined measurement methodology.

Accounting Rules and Normalisation Adjustments

The normalisation schedule should address the treatment of one‑time or non‑recurring items (restructuring charges, litigation settlements, asset impairments), related‑party transactions that are not on arm’s‑length terms, buyer‑initiated changes to accounting policies or revenue recognition, and extraordinary events outside the target’s control (force majeure, regulatory changes). Each adjustment should be defined by reference to a specific IFRS standard or line item in the target’s historical financial statements. Parties should agree in advance on whether the target’s existing auditor or an independent firm will prepare the earn‑out calculation, and whether the post-completion adjustment process runs in parallel or sequentially with the earn‑out measurement.

Governance, Reporting, Access and Controls

Robust governance is the single best defence against disputes. The SPA should require the buyer to deliver monthly or quarterly management accounts within a stated deadline, grant the seller’s representative (or its appointed auditor) access to the target’s books and records on reasonable notice, establish a virtual data room for ongoing document sharing during the earn‑out period, and require prompt notification of any event that could materially affect the earn‑out KPI.

Accounting, Tax and Financing Implications

A recurring question in UAE transactions is whether an earn‑out is classified as debt under the buyer’s financing documents. The answer depends on the definitions in the relevant facility agreement. Many lender‑form documents define “Financial Indebtedness” broadly enough to capture contingent deferred consideration; if so, the earn‑out may count toward leverage ratios and require lender consent before payment. Counsel should review the buyer’s existing finance documents at the letter‑of‑intent stage and, where necessary, seek a lender waiver or carve‑out for the earn‑out obligation.

From a tax perspective, the UAE’s federal corporate tax regime (effective for financial years beginning on or after 1 June 2023) treats the earn‑out payment as part of the acquisition cost for the buyer and as disposal proceeds for the seller. The timing of recognition, at completion or upon earn‑out crystallisation, should be confirmed with tax advisers and documented in the SPA. Security traps also warrant attention: if the earn‑out is secured by a pledge over target shares or assets, the security interest may need to be registered and may interact with the target’s own security arrangements.

Earn‑outs Enforcement in the UAE, Courts, Arbitration and Practical Remedies

UAE Courts vs Arbitration, DIFC, ADGM and ICC

Earn‑outs are enforceable in the UAE across all major forums, but the choice of venue matters significantly. Onshore UAE courts apply the new CTL and follow Arabic‑language proceedings; they are the default for transactions governed by federal UAE law. The DIFC Courts and ADGM Courts operate under common‑law frameworks (English‑derived) and offer English‑language proceedings, experienced commercial judges and well‑developed interim relief mechanisms. For international investors, arbitration under DIAC, ICC or LCIA rules, seated in the DIFC or ADGM, is the most common choice because awards are enforceable under the New York Convention and the UAE Federal Arbitration Law.

Typical Remedies and Enforcement Mechanics

Where a buyer fails to pay a validly determined earn‑out amount, the seller can seek a money judgment or award for the outstanding sum plus interest. Injunctive relief may be available where the buyer is threatening to take actions (such as an asset sale or restructuring) that would defeat the earn‑out before measurement is complete. In arbitration, tribunal‑ordered interim measures and emergency arbitrator procedures provide expedited protection.

Evidence and Accounting Expert Appointments

Earn‑out disputes are document‑ and accounting‑heavy. Courts and tribunals routinely appoint independent accounting experts to review the earn‑out calculation, test normalisation adjustments and opine on compliance with the agreed accounting methodology. Under the new CTL, the rules governing expert evidence have been updated, industry observers expect this to make court‑appointed expert processes more rigorous and transparent, reinforcing the importance of maintaining a complete audit trail throughout the earn‑out period.

Common Earn‑out Disputes and How to Avoid Them

The following twelve‑point checklist addresses the most frequently litigated earn‑out issues and provides practical contract language suggestions for each:

1. Ambiguous KPI definitions. Use precise financial line‑item references, not generic terms. Include a worked example in the schedule.
2. Undefined normalisation adjustments. List every adjustment exhaustively; avoid open‑ended language such as “including but not limited to”.
3. Buyer manipulation of target operations. Insert conduct covenants restricting material changes to accounting policies, headcount, capital expenditure and revenue‑channel allocation.
4. Inadequate data access. Grant the seller quarterly reporting rights and annual audit‑access rights with defined notice periods.
5. Late delivery of earn‑out statement. Specify a hard deadline and state that failure to deliver triggers a deemed acceptance of the seller’s own calculation (or another defined consequence).
6. Failure to specify accounting standards. State IFRS and the reference period explicitly; address what happens if IFRS standards change during the earn‑out period.
7. Related‑party transactions. Require arm’s‑length terms for all intercompany dealings and exclude non‑arm’s‑length transactions from the KPI calculation.
8. Currency fluctuations. Specify the functional currency for the calculation and the exchange rate source and date for any conversions.
9. Change of control or asset disposal. Include an acceleration clause that deems the earn‑out payable (at a defined amount) if the buyer sells the target during the earn‑out period.
10. Unclear dispute escalation. Define “Calculation Dispute” narrowly and specify a sequential process: negotiation → expert determination → arbitration.
11. Missing interest provision. State that interest accrues on any overdue earn‑out payment at a specified rate from the due date.
12. No confidentiality safeguard. Include confidentiality obligations around the earn‑out statement, the expert’s report and any arbitration proceedings.

Dispute Resolution Clauses and Expert Determination

The hybrid approach, expert determination for calculation disputes and arbitration for legal disputes, has become the market standard in drafting earn‑outs for UAE SPAs. Expert determination is faster, less expensive and better suited to technical accounting questions; arbitration provides the procedural safeguards needed for disputes involving breach of conduct covenants, fraud or questions of contractual interpretation.

When drafting the expert determination mechanism, specify the appointing body (for example, the President of the DIFC Academy of Law or the ICAEW), the expert’s required qualifications (typically a senior partner at a Big Four or equivalent firm with UAE experience), the timeline for appointment and determination (usually 30 days for appointment, 60 days for the determination), confidentiality obligations, and cost allocation (commonly shared equally, with the losing party bearing costs if the determination deviates from one party’s position by more than a stated margin). The clause should confirm that the expert acts as an expert and not as an arbitrator, and that the determination is final and binding absent manifest error.

Practical Negotiation Playbook, Seller vs Buyer Perspectives

Seller priorities:

• Negotiate a lower threshold and higher cap to maximise upside.
• Insist on strong conduct covenants restricting buyer interference with the target.
• Require monthly reporting and unrestricted access to books.
• Push for an acceleration clause on change of control.
• Seek an escrow or holdback funded by the buyer to secure earn‑out payments.

Buyer priorities:

• Set a challenging threshold to ensure the earn‑out reflects genuine over‑performance.
• Retain operational flexibility, resist overly prescriptive conduct covenants.
• Cap the earn‑out at a fixed percentage of the total enterprise value.
• Limit the earn‑out period to 12 months to reduce integration friction.
• Prefer expert determination over arbitration for faster, cheaper resolution of calculation disputes.

Conclusion, Recommended Next Steps for Earn‑outs in UAE M&A

As the new Civil Transactions Law takes effect and earnout disputes continue to rise across the UAE, the margin for imprecise drafting has narrowed considerably. Counsel advising on earn‑outs in UAE M&A should prioritise the following actions: run a finance‑document audit to confirm whether the earn‑out triggers lender consent requirements, tighten KPI definitions with exhaustive normalisation schedules and worked examples, choose the right dispute forum (hybrid expert determination plus arbitration seated in the DIFC or ADGM is the market‑leading approach), and build monitoring governance, reporting cadence, access rights and data‑room controls, directly into the SPA. Practitioners who invest in rigorous front‑end drafting will protect their clients from the costly post‑completion disputes that are defining the 2026 deal landscape.
