How to Draft and Negotiate Earn‑outs in Swedish M&A (2026): Practical Rules, Tax Issues and Dispute‑avoidance

Earn-outs Sweden practice has grown noticeably heading into 2026, as buyers and sellers increasingly reach for contingent consideration to bridge valuation gaps in an M&A market defined by tighter completion mechanics and greater use of warranty and indemnity (W&I) insurance. This guide sets out, in a structured and practical way, when to use an earn-out in Swedish transactions, how to draft the core clauses and completion mechanics, the tax consequences for seller and buyer, how to design measurement rules that avoid disputes, and what enforcement options exist under Swedish law. It is written for buyers, sellers, private equity investors and in-house counsel evaluating contingent consideration in 2026 deals.

Throughout, legal and tax claims are anchored to authoritative Swedish sources so the drafting choices you make can be traced back to statute and official guidance.

Overview, What is an earn-out and why use earn-outs in Sweden?

An earn-out is a portion of the purchase price that becomes payable only if the acquired business meets agreed performance targets after completion. Rather than fixing the entire consideration at closing, the parties defer part of it and make it contingent on measurable outcomes, revenue, profit, contract renewals or defined events. In Swedish M&A, earn-outs are used to bridge disagreement between a seller’s optimistic forecast and a buyer’s more cautious view of future performance, allocating the risk of that uncertainty to the party best placed to influence it.

The 2026 market context matters. Contingent consideration is being negotiated alongside higher uptake of W&I insurance, which covers breaches of representations and warranties but does nothing to address future performance risk. That gap is precisely where earn-outs sit. Sellers increasingly push for clearer KPIs, minimised escrow and tax certainty, while buyers prioritise robust measurement rules, audit rights and enforceable dispute resolution. Earn-outs are most common where forecasts are genuinely uncertain, where management is being retained, or where the target operates in a sector, such as IT, transport or food, with volatile or contract-dependent revenue.

Types of contingent consideration in earn-outs Sweden deals

• Performance KPIs. Payment triggered by hitting operational milestones such as customer retention, product launches or contract renewals.
• Revenue or profit thresholds. The most common structure, keyed to top-line revenue, EBITDA or gross margin over a defined measurement period.
• Event-based triggers. Payment on the occurrence of a specific event, such as regulatory approval, a public-contract award, or completion of a key integration step.

Each type carries a different disputes profile. Revenue-based earn-outs are easier to measure but easier to manipulate through pricing or accounting choices; event-based triggers are binary and cleaner but reward less nuance. The drafting must match the metric to the commercial logic of the deal.

Eligibility, when to use an earn-out (who and when)

An earn-out is not always the right tool. It suits early-stage or high-growth targets where forecasts are uncertain, situations where the seller will remain involved in running the business, and deals where the buyer wants to align management incentives during an integration period. It is less appropriate where the value driver is a one-off working-capital adjustment (better handled by completion accounts) or where the buyer intends to restructure the business immediately, which makes clean measurement almost impossible.

Risk tolerance drives the choice. Sellers accept an earn-out to preserve upside they believe the buyer underestimates; buyers accept it to avoid overpaying for performance that may not materialise. Private equity buyers frequently favour earn-outs to retain and motivate founder-managers through the hold period, but they also scrutinise operational covenants carefully because their integration and bolt-on strategies can distort the earn-out metric.

Sector considerations for drafting earn-outs Sweden-wide

• Public procurement. Where the target holds public contracts, the Public Procurement Act (lagen (2016:1145) om offentlig upphandling, LOU) and its rules on material changes to contracts can affect whether contracts survive a change of control and how continuity is maintained, directly relevant if the earn-out metric depends on those contracts.
• IT. Recurring-revenue and renewal metrics dominate; churn definitions and treatment of new versus existing customers need precise drafting.
• Transport. Asset-heavy and contract-dependent; capex timing and route economics complicate EBITDA measurement.
• Food. Margin volatility from input costs means gross-margin metrics require agreed normalisation for extraordinary price movements.

Step-by-step: how to draft and negotiate an earn-out

This is the operational core of the guide. The five steps below take an earn-out from metric definition through to dispute resolution, with numbered sub-steps and short sample wording. Drafting earn-outs Sweden practitioners will recognise these as the recurring negotiation battlegrounds.

Step 1, Define the earn-out metric(s) and measurement period

1. Choose objective, verifiable KPIs, revenue, EBITDA, gross margin or contract renewals, and avoid subjective or discretionary measures that invite dispute.
2. Fix the accounting definitions. State whether measurement follows IFRS or Swedish GAAP (the Swedish Accounting Standards Board’s K3 or K2 frameworks), and specify the treatment of extraordinary and non-recurring items, related-party transactions and management charges.
3. Decide measurement frequency and look-backs. Single-period, multi-year cumulative and annual-tranche structures each behave differently; a cumulative measure reduces the incentive to shift revenue between periods.

The single most common cause of earn-out litigation is an ambiguous metric definition. If “EBITDA” is not exhaustively defined, the parties will disagree about what belongs in it. Attach a worked example calculation to the schedule so the formula is demonstrated on real or illustrative numbers.

Step 2, Set valuation methodology and calculation mechanics

1. Decide between a simple formula (for example, a multiple of EBITDA above a threshold) and a waterfall approach that pays incremental amounts across performance bands.
2. Define the adjustments. Pro forma adjustments for acquisitions or disposals during the period, carve-outs of buyer-driven costs, and the treatment of synergies must be spelled out.
3. Set caps, collars and floors. A cap limits total exposure for the buyer; a floor or collar protects the seller against marginal underperformance. State clearly how partial achievement is rewarded.

Earn-out valuation Sweden negotiations often turn on whether buyer-imposed costs, new group overhead allocations, integration expenses, transfer pricing charges, are added back before measurement. Sellers should insist that costs outside ordinary course and not agreed in advance are excluded from the calculation.

Step 3, Completion mechanics and operation

1. Decide how the earn-out interacts with the pricing mechanism. Under a locked-box, price is fixed by reference to a historic balance sheet; under completion accounts, price adjusts at closing. The earn-out schedule must align its baseline with whichever mechanism the deal uses.
2. Set out post-completion operating obligations. Define who runs the business during the measurement period, the standard of conduct (ordinarily “in the ordinary course consistent with past practice”), and any management service commitments.
3. Draft the permitted-actions and veto framework. List actions the buyer may not take without seller consent, closing product lines, changing accounting policies, diverting revenue to affiliates, and the carve-outs the buyer requires to run its group.

Completion mechanics Sweden practice increasingly favours the locked-box for deal certainty, but locked-box deals still require an earn-out baseline that is consistent with the locked-box accounts, otherwise the two mechanisms conflict.

Step 4, Remedies, payment mechanics and security

1. Define payment triggers precisely: the certification event, the deadline for payment, interest on late payment, and any right of set-off against warranty claims. Note that interest on late payment may be governed by the Swedish Interest Act (räntelagen (1975:635)) unless the parties agree otherwise.
2. Consider security. Deferred consideration can be supported by an escrow held by a trusted third party, a parent guarantee, or a pledge. Under the Swedish Companies Act (aktiebolagslagen (2005:551)), corporate approvals and any restrictions on distributions, loans or guarantees to related parties must be observed when structuring seller security.
3. Address tax gross-up and warranties. Include withholding gross-up language where cross-border payments are involved and seller warranties on tax residence and status.

A short sample payment clause: “Subject to certification of the Earn-Out Statement in accordance with Schedule X, the Buyer shall pay the Earn-Out Amount to the Seller within thirty (30) days of the Determination Date to the account notified by the Seller, without deduction save as required by law; any amount required to be withheld shall be grossed up so that the Seller receives the amount it would have received absent the withholding.”

Step 5, Dispute resolution and audit rights in earn-outs Sweden agreements

1. Grant audit and certification rights: the seller’s right to review the earn-out statement, access to underlying records, and a defined objection window.
2. Build an escalation ladder: good-faith negotiation, then expert determination for accounting questions, then arbitration or court for legal disputes.
3. Preserve interim measures and the ability to protect claims, including security for the earn-out amount pending determination.

A clean split between accounting disputes (expert determination) and legal disputes (arbitration) prevents the most costly deadlock, an expert being asked to decide questions of contractual interpretation they are not equipped to resolve.

Required documents

Effective measurement and enforcement depend on the parties preparing and exchanging a coherent set of documents. The table below lists the core instruments.

Timeline and deadlines, practical project timeline

The following timeline runs from term sheet to final earn-out payment or dispute resolution. Parties should also keep the general contractual limitation period in mind when setting objection and claim deadlines under Swedish law (the default limitation period under the Swedish Limitation Act, preskriptionslagen (1981:130), is generally ten years, but shorter contractual periods are common), and confirm the position with local counsel for the specific claim type.

Costs and fees

Budgeting for an earn-out means budgeting for the whole lifecycle, not just the drafting. The main cost drivers are legal fees, accounting and audit work for each measurement, any expert determination or arbitration, escrow administration and tax advisory. Figures below are indicative planning ranges only; complexity, deal size and disputes drive wide variation, and current fee rates should be confirmed with the relevant advisers and institutions.

For arbitration, the SCC publishes a cost calculator and schedule based on the amount in dispute; for advance tax rulings, an application is made to the Council for Advance Tax Rulings (Skatterättsnämnden) and is subject to its applicable fees. Confirm current figures directly from these sources.

Tax issues, earn-out tax treatment in Sweden

Tax is where earn-outs Sweden deals most often surprise the parties, because the timing of income recognition and the character of the payment can differ from the parties’ expectations. The general principle is that contingent consideration forms part of the sale price for the shares, but the precise timing and treatment depend on when the contingent right becomes definitive. Sellers and buyers should confirm the treatment for their specific structure with the Swedish Tax Agency (Skatteverket) guidance and, where amounts are material, consider seeking an advance ruling from the Council for Advance Tax Rulings (Skatterättsnämnden).

Seller tax treatment, sale price allocation and timing

For a seller, an earn-out is generally treated as additional consideration for the disposal of shares rather than as ordinary income, provided it genuinely represents purchase price and is not disguised remuneration for continued employment. The distinction matters enormously: capital gains treatment on a share sale is taxed under the Income Tax Act (inkomstskattelagen (1999:1229)) very differently from employment income. Where the seller remains employed and the earn-out is conditioned on continued service, there is a real risk of recharacterisation as salary. Sellers should structure the earn-out so that entitlement does not depend on remaining employed, and document the commercial rationale.

The timing of recognition depends on when the contingent amount crystallises into a definitive right, which is why the certification mechanics in the SPA carry tax as well as commercial consequences.

Buyer tax treatment, deduction and accounting

For a buyer acquiring shares, the earn-out typically increases the acquisition cost of the shares rather than generating a current deduction, since the cost of shareholdings is not ordinarily deductible against operating income. The accounting treatment of contingent consideration under the applicable framework, and any subsequent remeasurement, should be modelled at the outset because it affects reported earnings and covenant headroom. Where the earn-out could be recharacterised as remuneration for services, the buyer faces employer social contribution and reporting exposure, which is a further reason to draft the trigger away from continued employment.

Withholding, reporting and cross-border issues

Cross-border earn-outs raise withholding and reporting questions, and where the target and buyer sit in different jurisdictions the interaction with transfer pricing and international tax principles, including OECD guidance, may be relevant, for example where intra-group charges affect the earn-out metric. Where withholding may apply, a gross-up clause protects the seller’s expected net receipt, and the buyer will want seller warranties on tax residence and status. Skatteverket guidance and, for material transactions, an advance ruling are the appropriate way to obtain certainty rather than relying on assumption.

Dispute-avoidance and enforcement (arbitration versus courts)

The best dispute strategy is prevention through precise drafting, but even well-drafted earn-outs generate disputes because the seller’s payment depends on the buyer’s post-completion conduct. Earn-out disputes Sweden practice centres on three defences: robust audit and certification clauses, a clear choice of forum, and access to interim measures.

Designing robust audit and certification clauses

The seller needs a genuine right to verify the earn-out statement, access to accounting records, management accounts and the underlying data sources agreed in the schedule, together with a defined objection window and a mechanism for appointing an independent auditor or expert to resolve accounting disagreements. Expert determination should be reserved for questions of calculation; questions of contractual interpretation should be routed to the chosen legal forum.

Choosing arbitration seat, language and governing law in earn-outs Sweden agreements

Arbitration is a dominant choice for M&A disputes in Sweden. Proceedings seated in Sweden are governed by the Swedish Arbitration Act (lagen (1999:116) om skiljeförfarande), and institutional arbitration under the rules of the Arbitration Institute of the Stockholm Chamber of Commerce (SCC) is widely used, offering confidentiality and specialist arbitrators. The clause should fix the seat, language and governing law, and specify SCC rules where institutional administration is wanted. Sweden’s arbitration-friendly framework and its position as a party to the New York Convention make Swedish-seated awards readily enforceable across borders, an important consideration where the seller or buyer sits outside Sweden.

Interim measures and injunctions in Sweden

Interim relief, including security measures for a disputed claim, is available under the Swedish Code of Judicial Procedure (rättegångsbalken) through the general courts, and in urgent cases through emergency arbitrator procedures under the SCC rules before the tribunal is constituted. Preserving the ability to secure the claim is particularly important where deferred consideration is unsecured and the buyer’s covenant strength may deteriorate. For guidance on contract interpretation, published judgments of the Högsta domstolen (Supreme Court) are the authoritative reference.

What changed in 2026, practical implications

Three shifts define earn-outs Sweden practice in 2026. First, W&I insurance uptake has continued to rise, sharpening the division of labour between insurance (which covers warranty risk) and earn-outs (which cover future performance), the two are complements, not substitutes. Second, negotiation has tightened around completion mechanics, with more detailed permitted-actions lists and operating covenants to protect the earn-out metric from buyer interference. Third, sellers are pushing harder for tax certainty up front, driving greater use of advance rulings and more careful separation of purchase price from employment consideration. The likely practical effect is longer, more detailed earn-out schedules and more front-loaded tax analysis.

Common pitfalls and negotiation red flags

• Vague KPI definitions. Undefined “EBITDA” or “revenue” is the leading cause of dispute; define every term and attach a worked example.
• Open adjustment baskets. Broad, undefined adjustment rights let one party re-engineer the result; cap and enumerate adjustments.
• No control on buyer operations. Without operating covenants, a buyer can lawfully depress the metric; negotiate conduct restrictions and a “change of business” protection.
• Employment-linked triggers. Conditioning payment on continued service risks recharacterisation as salary for tax; decouple entitlement from employment.
• Mismatched pricing baseline. An earn-out baseline inconsistent with a locked-box or completion-accounts mechanism creates internal conflict; align them.
• Weak dispute clause. Failing to separate accounting from legal disputes, or omitting interim relief, leaves the seller exposed.

Earn-out versus alternatives, comparison

Practical drafting checklist and sample clause annex

The following checklist consolidates the drafting priorities above into a working list for counsel finalising an earn-out schedule.

• Define each metric exhaustively with a worked example attached.
• State the accounting framework and the treatment of extraordinary and related-party items.
• Align the earn-out baseline with the locked-box or completion-accounts mechanism.
• Include operating covenants, a permitted-actions list and buyer carve-outs.
• Set caps, collars, floors and clear partial-achievement rules.
• Provide audit and certification rights with a defined objection window.
• Split accounting disputes (expert) from legal disputes (arbitration).
• Fix the seat, language, governing law and SCC rules for arbitration.
• Add tax gross-up wording and seller tax warranties; decouple triggers from employment.
• Provide security for deferred consideration and confirm corporate approvals.

Sample measurement clause: “The Earn-Out Amount shall be calculated by reference to the Adjusted EBITDA of the Target for the Measurement Period, determined in accordance with the Accounting Policies set out in Schedule X applied consistently, excluding any cost, charge or transaction imposed by the Buyer or any member of its group outside the ordinary course of the Target’s business and not agreed in writing by the Seller.”

Disclaimer: This guide is general information about earn-outs Sweden practice and is not legal or tax advice. Earn-out structuring depends on the specific facts, sector and cross-border profile of each deal. Readers should engage qualified Swedish counsel and tax advisers before relying on any structure or sample wording set out above.

Conclusion

Earn-outs Sweden deals succeed or fail on the quality of the drafting long before any payment falls due. The recurring lessons from Swedish M&A practice in 2026 are consistent: define the metric exhaustively, align the earn-out baseline with the pricing mechanism, protect the seller with operating covenants and audit rights, resolve tax character and timing up front with Skatteverket or an advance ruling where the amounts justify it, and choose a clean, arbitration-led dispute pathway. Handled with that discipline, an earn-out bridges a valuation gap and aligns incentives; handled loosely, it converts a completed deal into a multi-year dispute.

Buyers, sellers and their advisers should treat the earn-out schedule as one of the most heavily negotiated parts of the agreement and take specialist Swedish legal and tax advice before signing.
