A buyer signs an acquisition agreement and later refuses to complete. It points to lost customers, a regulator inquiry, weaker forecasts, or a market shock. The seller says the event falls within a carve-out. A Material adverse change dispute UAE. case can decide whether the deal completes, the deposit is lost, or damages follow.
Quick Answer
A Material adverse change dispute UAE. is decided first by the acquisition agreement. The party invoking the clause must prove the defined event, materiality, duration, notice compliance, and any carve-out exception. UAE law also requires contractual performance in good faith under Article 221 of Federal Decree-Law No. 25 of 2025. Statutory hardship and force majeure are separate doctrines. The result depends on the clause, disclosure record, financial evidence, conduct, and chosen forum.
Freeze the evidence at once. Compare the target’s position at signing with the position when the notice was served. Test the event against every definition, carve-out, threshold, and notice requirement. Avoid an unconditional refusal to complete until counsel assesses repudiation risk.
The buyer should issue a precise notice tied to the clause. The seller should answer each asserted trigger and reserve its rights. Both sides should examine negotiated solutions without weakening their litigation or arbitration position.

What A MAC Clause Actually Does
A material adverse change clause allocates risk between signing and completion. Some agreements use the term material adverse effect. The clause may operate as a condition precedent, termination right, representation qualifier, or combination.
There is no substitute for the wording. One agreement may focus on the target’s business and financial condition. Another may include prospects, licensing, key contracts, or an identified facility.
- The definition identifies the adverse change that can trigger relief.
- The threshold states how serious and lasting the effect must be.
- Carve-outs allocate general market and systemic risks to the buyer.
- A disproportionate-effect exception may return part of a carved-out risk to the seller.
- The remedy may permit termination, delayed completion, price adjustment, or another response.
- Notice terms control when, how, and to whom the claim must be made.
UAE Contract Law Framework
Performance And Good Faith
Federal Decree-Law No. 25 of 2025 promulgated the new Civil Transactions Law, effective from 1 June 2026. Article 221 requires performance according to the contract and consistently with good faith.
Article 221 also extends the contract beyond express words to requirements arising from law, custom, and the obligation’s nature. Good faith does not rewrite an agreed MAC allocation, but it affects performance and conduct.
Article 222 permits a party to withhold performance in a bilateral contract when reciprocal obligations are due and the other party has not performed. Whether it applies depends on the completion obligations and facts.
Negotiations And Disclosure
Article 121 requires pre-contract negotiations and their termination to follow good faith. A party negotiating or ending negotiations in bad faith may owe actual loss, subject to the Article’s limits.
Article 122 addresses disclosure of decisive information. It places the burden of proving concealment on the complaining party and the burden of proving disclosure on the party said to hold that information.
These provisions can matter when the alleged adverse event existed before signing or when a disclosure dispute overlaps the MAC argument.
Hardship And Force Majeure
Article 224 addresses exceptional, general, unforeseeable circumstances that make performance onerous and threaten serious loss. The court may reduce the obligation reasonably or rescind after balancing both sides.
Article 236 addresses force majeure that makes performance impossible. In a bilateral contract, corresponding obligations are extinguished and the contract is automatically rescinded when full impossibility occurs.
A negotiated MAC clause is different. It can allocate a defined risk even when performance remains possible. Parties should not use hardship or force majeure as shorthand for a contractual MAC test.
Material Adverse Change Dispute UAE Decision Points
Materiality
The claimant must connect the event to the clause’s protected subject. A serious headline is not enough if the agreement requires a measurable effect on earnings, assets, operations, or a specified license.
Duration matters. A brief disruption may fail where the clause addresses durable impairment. Forecasts should show the assumptions, period, and sensitivity to recovery.
Carve-Outs
Common carve-outs include general economic conditions, industry changes, changes in law, war, pandemics, market price movements, and effects caused by announcing the transaction.
The agreement may return a carved-out event to the MAC definition when the target suffers disproportionately against comparable businesses. Peer selection and reliable market data then become central.
Knowledge And Disclosure
A buyer may face difficulty relying on a risk that was fairly disclosed or clearly known at signing. The contract may contain express knowledge qualifiers, anti-sandbagging wording, or a disclosure standard.
The disclosure letter, data room index, diligence questions, management presentations, and internal investment papers should be reviewed together. Selective extracts can misstate what the buyer actually knew.
Notice And Remedy
A notice should identify the clause, event, dates, supporting information, and relief asserted. The contract may require notice within a short period or before the long-stop date.
A vague notice can fail even when a serious event occurred. The sender must also avoid language that becomes an independent refusal to perform before the contractual right is established.

Valuation And Expert Analysis
Financial experts should apply the clause’s metric, not a generic valuation model. They may compare revenue, EBITDA, cash flow, assets, customers, or regulatory value over the relevant period.
The expert should distinguish the event’s effect from trends already embedded in the signing forecast. Sensitivity analysis can test materiality under reasonable recovery assumptions.
Legal counsel should define the contractual questions before expert work begins. Otherwise, a detailed report may answer a commercial question that the clause never asks.
Practical Steps For The Buyer
- Map the event to every element of the MAC definition.
- Test exclusions and the disproportionate-effect exception.
- Quantify size, duration, and recovery assumptions with finance evidence.
- Confirm what diligence disclosed and what the decision-makers knew.
- Comply exactly with notice, consultation, cure, and timing terms.
- Reserve rights without making an unnecessary final refusal to complete.
- Assess whether hardship, force majeure, misrepresentation, or breach provides a separate route.
Practical Steps For The Seller
- Demand particulars of the event and every clause relied upon.
- Show how the effect falls inside a carve-out or remains temporary.
- Preserve evidence of disclosure, buyer knowledge, and deal financing.
- Compare the target with appropriate peers using consistent data.
- Continue satisfying covenants and completion obligations where possible.
- Reserve claims for damages, deposit consequences, or specific performance where available.
- Consider a negotiated extension, cure plan, or price mechanism.
Evidence And Documents Needed
- Signed acquisition agreement, schedules, and all amendments.
- Disclosure letter, data room index, and diligence correspondence.
- Management accounts, audited statements, forecasts, and budgets.
- Customer, supplier, regulator, and insurer correspondence.
- Board, investment committee, and financing papers.
- Peer and market data supporting or opposing disproportionate impact.
- Notices, meeting minutes, and settlement communications.
- Expert accounting, valuation, technical, or industry evidence.
Contemporaneous evidence usually carries more weight than a reconstruction prepared after the dispute. Preserve original files, document versions, and the chronology of decisions.
Forum And Remedies
The acquisition agreement may select onshore courts, DIFC or ADGM courts, or arbitration. The forum affects procedure, language, confidentiality, interim relief, experts, and enforcement.
Possible remedies depend on the contract and governing law. They may include completion, termination, damages, deposit consequences, price adjustment, declaratory relief, or urgent measures preserving assets and evidence.
An arbitration objection can be lost if not raised correctly. Parties should review the dispute clause before taking a substantive procedural step.

Common Mistakes And Risks
- Treating bad performance as automatically material.
- Ignoring carve-outs or peer comparison language.
- Serving a notice without contractual particulars.
- Using post-dispute forecasts without explaining changed assumptions.
- Confusing a MAC clause with hardship or force majeure.
- Refusing completion before confirming the contractual right.
A mistaken refusal can expose the buyer to a breach claim. The seller also takes risk if it conceals a serious development or insists on completion despite an established termination right.
Professional Contribution From Faris Raian
Faris Raian, Managing Partner at Leaders Advocates, notes that these disputes often turn on carve-out drafting and contemporaneous evidence. The dramatic event alone rarely resolves the legal test.
He advises both sides to collect signing-date knowledge records and comparable company data immediately. That evidence helps separate a target-specific impairment from a general market change.
How A Lawyer Can Help
Counsel can interpret the clause, direct the evidence hold, draft or answer the notice, and coordinate financial experts. A lawyer can also protect the forum position and assess urgent relief.
The strategy should compare contractual remedies with statutory routes under Articles 224 and 236. It should also address negotiation risk under Articles 121 and 122 where pre-signing disclosure is disputed.
