Purpose of this guide: This is a practical, clause‑level resource on drafting, negotiating and enforcing earn‑outs in South African M&A for 2026. It is written for in‑house counsel, private equity teams, transactional lawyers and dispute practitioners who need decision‑ready guidance rather than a high‑level overview.
Earn‑outs south africa deals are becoming a defining feature of mid‑market and private equity transactions in 2026, as regulatory scrutiny and evolving merger notification thresholds push parties toward contingent structures that bridge valuation gaps. An earn‑out defers part of the purchase price and ties it to the target’s future performance, allowing a buyer to hedge against an uncertain valuation while giving a seller the opportunity to capture the upside it believes the business will deliver. The commercial appeal is obvious, but the legal risk is considerable: poorly drafted contingent consideration is one of the most litigated features of post‑closing M&A.
For buyers, the core objectives are protecting against overpayment, aligning management incentives and retaining key sellers through a measurement period. For sellers, the priority is preserving the integrity of the metric, controlling the conduct of the business post‑closing and securing payment. The single most important takeaway is this: the value of an earn‑out lives or dies in the drafting. Precise measurement mechanics, disciplined governance during the earn‑out period and a clearly chosen enforcement route are what separate a workable deal from a multi‑year dispute.
An earn‑out is a contractual mechanism under which a portion of the consideration payable for a business or shares is contingent on the target achieving defined financial or operational targets after completion. The party entitled to receive the contingent payment is often described as the earn‑out beneficiary; the payment obligation crystallises only when a defined trigger is met over a measurement period. Getting the vocabulary right at the term‑sheet stage prevents costly ambiguity later.
Glossary:
The most common structures measure against a financial metric, revenue, gross profit or EBITDA, over a fixed period. Revenue‑based earn‑outs are simpler to calculate and harder to manipulate but reward top‑line growth even where margins deteriorate. EBITDA‑based earn‑outs align more closely with underlying value but invite disputes over cost allocation, intercompany charges and accounting policy. Milestone earn‑outs tie payment to discrete events, regulatory approval, a product launch, retention of a named customer, and suit businesses where value is concentrated in a specific outcome rather than steady financial performance.
Whatever metric is chosen, it must be defined with forensic precision. State the accounting framework, the treatment of extraordinary items, the handling of acquisitions or disposals during the period, and whether the metric is indexed for inflation or currency movement. Where the target operates across currencies, specify the conversion rate and the date on which it is fixed. An undefined metric is the most frequent source of earn‑out disputes south africa practitioners encounter.
The agreement should fix the measurement period start and end dates, the date on which earn‑out accounts must be prepared, and the payment date following determination. Caps limit the buyer’s total exposure; floors or minimum guarantees give the seller downside protection. Collars, combining a cap and a floor, are increasingly common in private equity deals where both sides want certainty around the range of contingent outcomes.
Earn‑outs are not a default; they are a targeted solution to a specific problem. The classic use case is a valuation gap: the seller values the business on optimistic forward projections and the buyer is unwilling to pay for unproven growth. An earn‑out lets the parties agree a base price now and defer the disputed portion until performance is known. Other rationales include retaining and incentivising founder‑managers, sharing the risk of an integration or expansion, and structuring the acquisition of a minority or growth stake.
Six questions to decide if an earn‑out is appropriate:
Buyers should treat the earn‑out as a risk‑transfer tool, not merely a discount. The key concerns are avoiding overpayment for performance that does not materialise, retaining operational control after closing, and ensuring the metric cannot be gamed by the seller during the period. A buyer that concedes broad conduct restrictions may find its post‑closing integration frozen for years; a buyer that concedes nothing may face an argument that it deliberately suppressed performance.
Sellers must protect the integrity of the metric and their ability to influence it. This means negotiating conduct‑of‑business covenants that prevent the buyer from starving the target of resources, redirecting revenue to affiliates or loading it with costs. Sellers should also seek minimum guarantees, security or escrow, and clear audit rights so they can verify the earn‑out calculation independently.
Private equity buyers frequently use earn‑outs to align founders with the fund’s value‑creation plan while deferring a portion of consideration to a realisation event. Where the seller retains a minority stake, the earn‑out interacts with shareholders’ agreement provisions, drag and tag rights, and reserved matters. Structuring these instruments coherently, so the earn‑out, the equity and the governance rights pull in the same direction, is central to a well‑drafted earn‑out agreement south africa deal teams can rely on.
Drafting earn‑outs south africa transactions demands precision at the level of the individual clause. The sections below set out the anchor components of a defensible earn‑out and offer annotated sample language. All sample wording below is illustrative and non‑binding, and must be adapted to the specific transaction and reviewed by qualified counsel.
The trigger clause must state the metric, the threshold, the period and the formula converting performance into a rand amount. A simple linear formula might provide that the earn‑out equals a stated multiple of the amount by which measured EBITDA exceeds a target, subject to a cap. Avoid open‑textured language such as “reasonable performance” or “profitability” without a defined calculation. Every input into the formula should be either a defined term or a line item in the agreed accounts.
Specify who prepares the earn‑out accounts, within what period, and to what standard. Grant the seller a defined window to review, access to underlying books and records, and the right to appoint an independent accountant. Set out the consequences of failing to deliver accounts on time, for example, deeming the seller’s estimate correct, or triggering interest. Audit rights that are vague or time‑limited are frequently the flashpoint in post‑deal earn‑out disputes.
State the accounting framework expressly, typically IFRS as applied consistently with the target’s historical policies, and address the hierarchy where the framework and past practice conflict. Fix the accounting reference date, the format of the earn‑out statement and the treatment of provisions, one‑off items and related‑party transactions. Consistency of accounting policy across the base‑year accounts and the earn‑out accounts is essential; a change in policy can distort the metric and generate a dispute even where both sets of accounts are individually correct.
Conduct‑of‑business covenants are the seller’s principal protection and the buyer’s principal constraint. Draft them to preserve the target’s ability to generate the metric, restricting the diversion of business to affiliates, the imposition of non‑arm’s‑length charges, and the withdrawal of resources, while preserving the buyer’s legitimate operational freedom. A balanced clause obliges the buyer to run the business in good faith and in the ordinary course, without requiring it to maximise the earn‑out at the expense of the wider group.
Where founders remain to drive the earn‑out, align their service agreements, restraint provisions and any leaver terms with the earn‑out mechanics. Address what happens to the earn‑out if a key manager resigns, is dismissed for cause, or leaves as a good leaver. Misaligned retention terms, where a manager can walk away yet still claim the full earn‑out, or forfeit it despite strong performance, undermine the entire structure.
Set out the maximum and minimum contingent amounts and how they interact with any escrow. Where an escrow secures both warranty claims and the earn‑out, the priority and release mechanics must be unambiguous. Specify the escrow release triggers, the treatment of interest, and what happens to escrowed funds if a dispute is unresolved at the scheduled release date.
Provide for events outside both parties’ control, regulatory change, force majeure, loss of a material customer for reasons unconnected to conduct. Decide whether such events adjust the metric, extend the period, or are simply borne by the seller. Carve‑outs should be drafted as closed lists wherever possible to avoid arguments about whether a given event qualifies.
Sample clause, illustrative and non‑binding; adapt and obtain advice before use.
“Subject to clauses [X] (Cap) and [Y] (Conduct of Business), the Purchaser shall pay to the Seller an Earn‑Out Amount calculated as [multiple] times the amount (if any) by which the Adjusted EBITDA of the Company for the Measurement Period exceeds the Target EBITDA, provided that the Earn‑Out Amount shall not exceed the Cap. ‘Adjusted EBITDA’ means earnings before interest, tax, depreciation and amortisation as shown in the Earn‑Out Accounts, prepared in accordance with IFRS applied consistently with the Company’s accounting policies used in the Base Accounts, and excluding [defined one‑off items]. The Purchaser shall deliver the Earn‑Out Accounts to the Seller within [number] Business Days after the end of the Measurement Period.
The Seller may, within [number] Business Days of receipt, dispute the Earn‑Out Accounts by written notice specifying each item in dispute, whereupon the matter shall be referred to an Independent Accountant acting as expert and not as arbitrator, whose determination shall be final and binding save in the case of manifest error or fraud.
Drafting notes: the reference to conduct‑of‑business protects the seller’s metric; the IFRS‑consistency wording prevents policy‑shifting; and the expert‑determination mechanism resolves accounting disputes without full litigation while preserving recourse for manifest error or fraud.
Negotiating an earn‑out is an exercise in allocating both risk and control. The buyer’s typical red lines are the cap, operational freedom during the period and protection against seller manipulation of the metric. The seller’s priorities are the integrity of the calculation, conduct covenants, security for payment and a minimum guarantee. The middle ground usually involves a collar, a good‑faith conduct standard, escrow with defined release triggers, and a fast, low‑cost route for resolving calculation disputes.
Address the earn‑out at the term‑sheet stage, not in final drafting. The metric, period, cap and conduct principles should be agreed in principle before extensive legal spend. Diligence should test whether the chosen metric is measurable from the target’s existing systems; if the accounts cannot readily produce the metric, the risk of dispute rises sharply.
Sellers should insist on defined, enforceable access to the books, records and management of the target during and after the measurement period. Buyers should scope that access to what is necessary to verify the metric, protecting confidential and competitively sensitive information. A clear access regime prevents the standoff that so often precedes formal disputes.
Distinguish between accounting disputes and legal disputes. Accounting disagreements are best referred to an independent accountant acting as an expert, whose determination is final on matters of calculation. Legal disputes, breach of covenant, alleged bad faith, fraud, should be reserved for the courts or arbitration. Conflating the two in a single clause produces jurisdictional arguments that delay resolution.
The best dispute strategy is prevention through disciplined governance. Because the earn‑out depends entirely on data generated after closing, the parties should agree in advance how that data will be produced, shared and reconciled.
Fix a regular reporting cadence, monthly or quarterly management accounts in an agreed format, so the earn‑out metric is visible throughout the period rather than only at the end. Early visibility surfaces disagreements while they are small and lets the parties correct course before the final calculation.
Build an escalation ladder: management‑level reconciliation first, then referral to senior representatives, then independent expert determination for accounting items and arbitration or litigation for legal disputes. A structured ladder discourages parties from escalating prematurely and keeps costs proportionate.
Where the seller’s representatives remain on the board, define their information rights and the target’s obligations under the Companies Act, 2008 regarding record‑keeping and directors’ duties. Clear governance obligations reduce the scope for either party to allege that information was withheld or that the business was mismanaged to affect the metric.
When prevention fails, enforcement becomes the central question. Earn‑out enforcement in South Africa turns on contract law, the chosen dispute‑resolution forum, and, where cross‑border payments are involved, exchange control. Understanding the available remedies before a dispute arises allows deal teams to draft toward the enforcement route they actually want.
South African courts enforce earn‑out obligations as ordinary contractual claims. The primary remedies are specific performance, an order compelling payment of the earn‑out or delivery of the earn‑out accounts, declaratory relief settling the parties’ rights, and damages. Interim relief may be available to preserve the position pending final determination, for example to prevent the dissipation of escrowed funds. In construing the clause, the courts apply the interpretive approach confirmed in Natal Joint Municipal Pension Fund v Endumeni Municipality 2012 (4) SA 593 (SCA), which requires the words to be read in light of their context and the apparent purpose of the provision.
The practical lesson from Endumeni is that a court will not rescue a badly drafted formula, but it will give sensible commercial effect to language read in context, which is why precise, purposive drafting matters so much.
Many earn‑out agreements refer disputes to arbitration, often under the rules of the Arbitration Foundation of Southern Africa (AFSA). Domestic arbitration is governed by the Arbitration Act, 1965, while the recognition and enforcement of foreign arbitral awards is governed by the International Arbitration Act, 2017, which gives effect to the New York Convention. Arbitration offers confidentiality, a specialist tribunal, procedural flexibility and, for cross‑border deals, an award that is often more readily enforceable internationally than a court judgment. The trade‑offs are cost, the limited scope for appeal, and the fact that interim relief may still require a court.
When choosing arbitration, specify the seat, the rules, the number of arbitrators and the language, and coordinate the arbitration clause with any expert‑determination mechanism so the two do not overlap.
Where the seller is a non‑resident, earn‑out payments engage South African exchange control administered by the Financial Surveillance Department of the South African Reserve Bank, acting through authorised dealers. Deal teams should confirm the approvals or reporting required to remit contingent consideration offshore, and build any such requirements into the payment mechanics so that a valid award or judgment does not stall at the point of remittance. Cross‑border enforcement of foreign arbitral awards under the International Arbitration Act, 2017 is generally more straightforward than enforcement of foreign court judgments, which reinforces the case for arbitration in international transactions.
The trend in South African commercial adjudication is toward contextual, purposive interpretation of commercial agreements, following Endumeni and subsequent Supreme Court of Appeal and Constitutional Court decisions on contractual interpretation. For earn‑outs, this means courts and tribunals will scrutinise the commercial purpose of the metric and the conduct covenants, and will be reluctant to accept interpretations that defeat the evident bargain. Parties who document their commercial intention clearly, in recitals and defined terms, put themselves in a stronger position if the clause is later tested.
Checklist, enforcing a disputed earn‑out payment:
The buyer’s earn‑out accounts show EBITDA below the trigger; the seller disputes the allocation of central overheads. The model response is to invoke the expert‑determination clause, provide the seller full access to the working papers, and refer only the disputed line items to the independent accountant. Where the agreement fixed IFRS applied consistently with historical policy, the expert can resolve the item without litigation.
The seller alleges the buyer diverted a key contract to an affiliate, suppressing revenue. This is a legal dispute for the courts or arbitration, not the expert. The seller should marshal evidence of the diversion and rely on the conduct‑of‑business covenant; the buyer should demonstrate that the decision was a bona fide ordinary‑course judgment. The outcome turns on the drafting of the covenant and the good‑faith standard.
The buyer is itself acquired mid‑period, or restructures the target. A well‑drafted agreement addresses this expressly, accelerating the earn‑out, deeming the metric, or requiring the successor to assume the obligation. Where the agreement is silent, the parties are left to argue interpretation, which is precisely the uncertainty good drafting should eliminate.
The seller alleges the accounts were deliberately manipulated. Fraud is expressly carved out of the finality of expert determination in the sample clause above, so the seller can pursue the claim in court or arbitration notwithstanding an adverse expert finding. The response requires forensic accounting evidence and, potentially, urgent interim relief to preserve funds.
Contingent consideration in M&A carries tax, accounting and regulatory consequences that frequently drive structural choices. This section is a high‑level primer; specific advice should be obtained on every transaction.
The South African Revenue Service treatment of contingent consideration raises questions of characterisation, timing of recognition and the base cost or proceeds attributable to the deferred amount. When the contingent portion is recognised, and whether it is treated as capital or revenue, materially affects both parties’ liabilities. Because the amount is uncertain at closing, timing questions are particularly acute, and the parties should model the tax outcome under a range of earn‑out scenarios rather than only the expected case, applying the current provisions of the Income Tax Act and relevant SARS guidance.
Under IFRS, contingent consideration in a business combination is generally recognised at fair value at the acquisition date and remeasured in subsequent periods, which can produce volatility in the acquirer’s results as the estimated payout changes. Aligning the accounting framework in the sale agreement with the target’s ordinary reporting reduces the risk that the earn‑out metric and the group’s statutory accounts diverge.
Where the transaction is a notifiable merger under the Competition Act, 1998, it must be notified to and cleared by the competition authorities before implementation. Intermediate and small mergers are dealt with by the Competition Commission, while large mergers require approval by the Competition Tribunal, subject to the monetary thresholds set from time to time by the Minister of Trade, Industry and Competition, deal teams should confirm the current thresholds and any public‑interest considerations at the outset. Post‑completion, applicable corporate changes must be filed with the Companies and Intellectual Property Commission (CIPC) in line with the Companies Act, 2008. For cross‑border consideration, exchange control approvals administered through the South African Reserve Bank framework must be secured.
Sequencing these regulatory steps around the earn‑out payment mechanics avoids the situation where a payment is contractually due but cannot lawfully be made.
The following tools distil the guidance above into working checklists and a comparison of the principal payment mechanisms, so that earn‑outs south africa deal teams can select and draft the right structure efficiently.
A downloadable “Earn‑out clause checklist & sample clauses (South Africa, 2026)” accompanies this guide.
| Mechanism | Measurement metric | Typical seller risk | Typical buyer protection | Enforcement complexity | Sample industries |
|---|---|---|---|---|---|
| Formulaic (revenue) | Top‑line revenue over period | Rewards revenue even if margins fall; limited | Simple to verify; cap limits exposure | Low, objective and auditable | Services, distribution, subscription |
| Formulaic (EBITDA) | Adjusted EBITDA over period | Cost allocation and policy disputes | Aligns payment with underlying value | Medium, accounting disputes common | Manufacturing, established trading businesses |
| Milestone | Discrete events or approvals | Binary outcome; all‑or‑nothing | Pays only on defined achievement | Medium, depends on clarity of milestone | Pharma, tech, resources, regulated sectors |
| Hybrid | Combination of metric and milestones | Complexity increases dispute surface | Balances financial and event‑based value | High, multiple triggers to enforce | Growth‑stage and private equity deals |
The right adviser for an earn‑out combines two skill sets that do not always sit together: precise transactional drafting and practical enforcement experience. Look for counsel who have drafted and defended contingent consideration clauses, who understand the interplay with warranties, escrow and shareholders’ agreements, and who can advise on both the accounting and the litigation dimensions of a dispute. For international deals, cross‑border enforcement and exchange control fluency are essential.
South Africa’s largest full‑service firms and its specialist corporate boutiques both handle complex earn‑out mandates; the choice depends on deal size, sector and whether a dispute is anticipated. When budgeting, factor in that senior transactional counsel command premium rates but often reduce total cost by preventing disputes through better drafting. Diversity and local market knowledge are also legitimate selection criteria, particularly where the deal has a strong domestic footprint.

For deeper guidance, watch for the supporting resources in this series, including earn‑out dispute case studies and a dedicated primer on the tax treatment of contingent consideration in South Africa.
Well‑structured earn‑outs south africa transactions reward the discipline invested in them at the drafting stage. Define the metric with precision, govern the earn‑out period rigorously, choose the enforcement route deliberately, and instruct counsel who can carry the clause from term sheet to payment, or, if necessary, through a dispute. Do that, and the earn‑out becomes what it should be: a bridge across a valuation gap, not a source of years of litigation.
