How to Structure Seller Financing and Earn-outs That Work in Danish Mid-market M&A

To structure seller financing earn outs that survive contact with a real Danish deal, you need more than a headline price, you need enforceable security, clean tax treatment, tightly drafted valuation metrics and a dispute mechanism that actually resolves KPI arguments. In the Danish mid-market, deferred consideration has become a routine bridge between an ambitious seller and a cautious buyer, allowing parties to share risk over the two or three years that follow completion. Yet the same instruments that unlock a deal, the seller note, the earn-out, the escrow holdback, repeatedly cause disputes when their mechanics are left vague.

This guide walks through the commercial and legal choices that matter under Danish law, with drafting tradeoffs, red flags and citations to official sources so you can move from theory to a defensible, negotiated position.

Executive Summary: Choosing Between Seller Financing and Earn-Outs

The first structuring decision is not “how much” but “which instrument.” Seller financing (a seller note or promissory note) defers a fixed, certain sum and shifts credit risk onto the seller; an earn-out defers a variable, performance-linked sum and shifts business risk onto both parties. A hybrid combines the two, a fixed deferred tranche plus a contingent upside. The right answer depends on how far apart the parties are on valuation, how confident each side is in the target’s forward performance, and what security the buyer can realistically offer.

Use this quick decision flow when you begin to structure seller financing earn outs that fit the deal:

• Prefer a seller note where the disagreement is about financing capacity, not value, the price is agreed but the buyer needs time to pay.
• Prefer an earn-out where the disagreement is about future performance, the seller believes in growth the buyer is not willing to pay for upfront.
• Prefer a hybrid where you need both certainty and alignment, a modest fixed deferral plus a capped performance kicker.

A short checklist for both sides: confirm the credit standing of the payer, agree the security package before term-sheet signature, define every valuation metric to accounting standard, fix the measurement period, and settle the dispute mechanism in advance rather than after the numbers land.

What Are Earn-Outs and Seller Financing, Core Concepts

An earn-out is a portion of consideration paid only if the target business hits defined financial or operational targets after completion, commonly EBITDA, revenue or a customer-retention metric measured over one to three years. A seller note is a fixed deferred obligation: the buyer promises to pay an agreed sum on a schedule, usually with interest, documented in a promissory note or loan instrument. Deferred consideration is the umbrella term for any part of the price paid after completion, and an escrow (or holdback) is a retained slice of the price parked with a third party or withheld by the buyer to satisfy warranty or indemnity claims.

Two short illustrations show how the balance of power shifts. In a seller-friendly earn-out, the metric is revenue (which the seller can influence even after handing over control), the measurement period is short, and the buyer covenants to run the business in the ordinary course. In a buyer-friendly earn-out, the metric is normalised EBITDA (harder to inflate), the period is longer, caps are tight, and the buyer retains broad operational discretion. Recognising which end of the spectrum a draft sits on is the fastest way to spot who is bearing the risk.

Typical Structures Used in Danish Mid-Market Deals

Danish mid-market transactions typically combine three building blocks: a cash payment at completion, a deferred element (seller note and/or earn-out), and an escrow or holdback for warranty exposure. A common pattern is a majority of consideration in cash at completion, a smaller earn-out tranche over one to three years, and an escrow released over a defined period. The exact split turns on sector volatility, buyer financing and the seller’s willingness to stay involved during the earn-out period, and the ranges vary widely deal to deal.

Security and Enforcement Options in Denmark

Deferred consideration is only as good as the security behind it. Danish law offers several routes to secure a seller note or an earn-out balance, each with distinct perfection and enforcement mechanics. The consolidated statutes governing corporate matters, creditor rights and enforcement are published on Retsinformation, the official Danish legal information portal, and any security package should be validated against the current wording of the relevant acts.

Share Pledge Mechanics and Registration

The most common security for a seller in a share deal is a pledge over the shares being sold or over shares in the buyer’s acquisition vehicle. Under Danish law, perfection of a share pledge depends on the type of shares and how ownership is evidenced. For shares recorded in a company’s owners’ register, notification and register steps matter; company registration is administered through the Danish Business Authority. Correct perfection is central to making a pledge effective against third parties and competing creditors, and the applicable requirements should be confirmed against current law. A pledge that is agreed but not properly perfected may be worthless in an insolvency of the buyer.

Practical drafting points for a share pledge include: identifying precisely which shares are charged, restricting further encumbrances, addressing voting rights during the pledge period, and setting clear enforcement triggers (typically payment default or breach of covenant). Where the buyer is a special-purpose vehicle with no other assets, a pledge over the target shares is often the seller’s single most valuable protection, but it also means that, on enforcement, the seller may end up owning back a business the buyer has run for a year or more.

Asset Security and Mortgages

Where the transaction is an asset deal, or where the buyer group holds real property or valuable movables, the seller may take security over specific assets. Danish law recognises charges over real property and certain registered assets, with perfection generally requiring registration to bind third parties. Broad “floating” security over a company’s assets is more limited than under some common-law systems, so sellers should not assume an all-embracing charge is available or effective. Each proposed asset charge must be checked against the applicable registration regime and the priority of existing lenders, a senior bank facility will almost always rank ahead of a seller’s deferred claim unless subordination is expressly agreed.

Guarantees and Third-Party Support

Where direct security is impractical, personal, parent-company or bank guarantees fill the gap. A parent guarantee makes a solvent group entity liable for the buyer’s deferred obligations; a bank guarantee (on-demand or conditional) gives the seller a call on a financial institution rather than on the buyer’s balance sheet. Bank guarantees are frequently the cleanest solution for a seller note because enforcement is fast and does not depend on the target’s post-completion performance. When structuring seller financing earn outs that rely on guarantees, confirm the guarantor’s standing, the exact trigger for a call, and whether the instrument is on-demand or requires proof of default.

Enforcement of Danish security and judgments runs through the enforcement court (fogedretten); the Danish Courts portal is the reference point for enforcement procedure and published case law.

Tax Treatment and Reporting for Deferred Consideration

Tax often determines whether a deferred structure is worth doing at all. The seller’s after-tax outcome depends on how and when the consideration is recognised, and the rules are set out in guidance published by the Danish Tax Agency (Skattestyrelsen). Because the interaction between capital gains timing, contingent consideration and cross-border withholding is complex, tax planning should begin before the term sheet is signed, not after.

Capital Gains Timing and Instalment Rules

For a Danish seller, the sale of shares generally engages capital gains rules, and the central practical question with deferred consideration is when the gain is recognised. Fixed deferred amounts under a seller note may be treated differently from contingent earn-out amounts whose value is uncertain at completion. The timing of recognition affects cash flow, a seller can face a tax liability before the corresponding cash arrives if recognition is accelerated to completion. Sellers should model the recognition point for each tranche and confirm the treatment against current Skattestyrelsen guidance, because the difference between recognising a contingent sum now versus when it crystallises can materially change the deal’s economics.

VAT and Indirect Tax Considerations

Share sales are commonly outside the scope of VAT, but asset deals can bring VAT and other indirect taxes into play, and the VAT position of transaction and advisory costs is not automatically recoverable. Where deferred payments relate to an asset transfer, parties should confirm whether any VAT falls due, and when, against Skattestyrelsen guidance. Do not assume that because a payment is deferred, its indirect-tax characterisation is deferred too.

Cross-Border Withholding and Treaty Checks

Where the seller is non-resident, or where deferred amounts carry interest paid across a border, withholding obligations and double-tax treaty relief must be checked. Interest on a seller note paid to a foreign lender can raise withholding questions distinct from the treatment of the capital element. Confirm the residence of each payee, the character of each payment (capital, interest or contingent), and the availability of treaty relief before drafting the payment schedule. Getting this wrong late in the process can force a renegotiation of net proceeds.

Valuation Metrics, KPIs and Anti-Manipulation Protections

Most earn-out disputes are, at root, definitional. If you want to structure seller financing earn outs that do not end in arbitration, the single most valuable investment is precise, accounting-anchored metric definitions and robust anti-manipulation protections.

Common KPI Definitions and Clause Language

The metric you choose allocates risk. Revenue is simple to verify but easy to inflate at the margin’s expense. EBITDA aligns better with value but invites arguments about what is “exceptional.” Gross margin and customer-retention metrics can capture quality of earnings that revenue misses. Whatever the metric, define it against a named accounting standard, specify the exact line items included and excluded, and set caps and floors so neither side faces unlimited swings. Fix the measurement period unambiguously, a “financial year” needs a defined start and end, and a stub period needs its own rules.

Accounting Adjustments and Dispute Points

Normalisation is where good-faith drafting breaks down. Buyers want to add back one-off costs and strip out non-recurring gains; sellers want to protect the earnings base they were paid for. List the permitted adjustments exhaustively rather than relying on a general “normalisation” formula, and state which accounting policies apply, those of the target before completion, or the buyer’s group policies afterwards. A change in accounting policy after completion can quietly move an earn-out out of the money, so the clause should freeze the relevant policies for the measurement period.

Anti-Manipulation Covenants and Minority Protections

Because the buyer controls the business during the earn-out, the seller needs covenants preventing value being shifted away from the measured metric. Typical protections include: an obligation to run the business in the ordinary course, restrictions on diverting revenue or customers to affiliates, limits on inter-company charges, a bar on discretionary decisions taken principally to depress the earn-out, and information and audit rights so the seller can verify the numbers. Buyers, in turn, resist covenants that fetter genuine business decisions. The negotiated middle ground usually pairs a good-faith operating covenant with a defined set of carve-outs for legitimate strategic changes.

Structuring Escrows, Holdbacks and Payment Mechanics

An escrow or holdback protects the buyer against warranty and indemnity claims by retaining part of the price. Sizing is a matter of judgement that varies with the risk profile revealed in due diligence, the strength of the warranty package and the seller’s ongoing solvency. A clean, low-risk business with strong warranties supports a smaller escrow; a business with identified contingent liabilities supports a larger one.

Escrow Agent Selection and Release Timeline

The escrow can sit with a bank, a law firm acting as agent, or a specialist provider. Where a Danish law firm holds funds, the arrangement must respect the profession’s client-money and conduct rules; the Danish Bar and Law Society (Advokatsamfundet) publishes guidance on lawyer conduct that is relevant to escrow and client-account arrangements. Release mechanics should specify: the release date or dates (often staged tranches over a defined period), the trigger for withholding against a notified claim, how disputed claims are resolved, and what happens to interest earned on the escrowed sum. A “claims bucket” structure, where different categories of claim draw on different portions, helps avoid the whole escrow being frozen by a single small dispute.

Interest, Default Remedies and Acceleration

A seller note should state the interest rate, payment frequency, and the consequences of default. An acceleration clause allows the seller to demand the whole balance on a payment default or covenant breach, and set-off provisions determine whether the buyer can net warranty claims against deferred payments. Sellers should resist broad set-off rights that let the buyer withhold deferred consideration on the basis of unquantified claims; buyers should insist on set-off for at least agreed or adjudicated claims. Aligning the escrow, the seller note and the earn-out set-off rules prevents the same claim being counted twice.

Dispute Resolution: Arbitration, Expert Determination and Danish Courts

Because deferred structures generate technical, numbers-driven disagreements, the dispute mechanism should match the nature of the dispute. Accounting and KPI questions are usually best sent to expert determination; broader contractual disputes suit arbitration or the courts.

Drafting an Effective Expert Determination Clause

Expert determination refers a defined technical question, typically the calculation of an earn-out metric or a completion-accounts adjustment, to an independent accountant whose decision the parties agree to treat as final and binding. To be effective, the clause must define the expert’s exact remit (only the disputed line items, not the whole contract), the appointment mechanism if the parties cannot agree, the timetable, cost allocation, and the standard the expert applies. A common failure is a clause so broad that the “expert” is effectively deciding legal questions, which invites challenge. Keep expert determination for arithmetic and accounting; route legal interpretation elsewhere.

Practical Enforcement Steps After Determination

Where a dispute goes to arbitration, the parties should specify Danish governing law, a seat in Denmark (commonly Copenhagen) and a recognised set of arbitral rules, such as those of the Danish Institute of Arbitration. Danish courts recognise and enforce arbitral awards under the applicable Danish arbitration legislation and international conventions, and the enforcement route runs through the courts administered via the Danish Courts portal. After an expert determination or award crystallises a sum, enforcement against the payer follows normal debt-enforcement steps, which is precisely why the security package agreed at the outset matters: a favourable determination is only useful if there is a solvent obligor or a perfected charge to enforce against.

Negotiation Tips, Red Flags and Drafting Checklist

Experienced counsel spot problems in a draft before they become disputes. When you set out to structure seller financing earn outs that hold up, watch for the recurring warning signs and use a disciplined checklist.

Sample Red Flags and Mitigation Language

• Vague KPI definitions. “EBITDA” without a defined accounting policy is an invitation to litigate. Mitigation: define every line item and freeze the policies.
• Unrestricted buyer control. A buyer free to reorganise, divert revenue or change accounting during the earn-out can lawfully starve it. Mitigation: ordinary-course covenants with defined carve-outs.
• Aggressive normalisation. An open-ended add-back right lets the buyer rewrite the earnings base. Mitigation: an exhaustive list of permitted adjustments.
• Insufficient or unperfected security. A seller note with no perfected charge is an unsecured loan to an SPV. Mitigation: agree and perfect security before signing.
• Broad set-off rights. A buyer withholding deferred sums against unquantified claims can weaponise minor disputes. Mitigation: limit set-off to agreed or adjudicated claims.
• No clean dispute route. Sending accounting disputes to full litigation is slow and expensive. Mitigation: a tight expert-determination clause for numbers.

The core drafting checklist for a term sheet and SPA: confirm payer creditworthiness; agree and perfect security; define each metric to an accounting standard; freeze accounting policies; fix measurement periods and caps/floors; include ordinary-course covenants and audit rights; size the escrow to the risk profile; set interest, acceleration and set-off terms; and specify governing law, seat and dispute mechanism.

Comparison Table: Seller Financing vs Earn-Out vs Hybrid

The three main structures allocate risk very differently. Seller financing gives the seller a fixed but credit-exposed claim; an earn-out gives the seller upside but transfers business risk and monitoring burden; a hybrid balances both. The table below summarises the practical tradeoffs to weigh when you structure seller financing earn outs that suit a specific Danish mid-market transaction.

Appendix: High-Level Clause Examples (Illustrative Only, Not Legal Advice)

The following are illustrative concepts, not drafting to be copied. They show the tradeoffs a properly drafted clause must resolve.

• Earn-out definition. An earn-out clause should tie the payment to a named metric, a defined accounting standard, a fixed measurement period, and an agreed cap and floor, leaving no room to argue about which figures count.
• KPI clause. The clause should list every included and excluded item, freeze the applicable accounting policies for the period, and set out the permitted normalisation adjustments exhaustively.
• Escrow release trigger. Release should occur on a stated date unless a claim has been notified in the required form and within the required period, with disputed portions retained until resolved.
• Seller note payment schedule. The note should state principal, interest rate, instalment dates, acceleration on default, and the security supporting repayment.

Each of these must be adapted to the specific deal and reviewed by Danish counsel, the value is in the precision, not the boilerplate.

Conclusion and Next Steps

To structure seller financing earn outs that genuinely work in Danish mid-market M&A, treat the deferred element as a project in its own right rather than an afterthought to the price. Agree and perfect security before signing, model the tax recognition of each tranche against Danish Tax Agency guidance, define every valuation metric to an accounting standard, size the escrow to the real risk profile, and choose a dispute mechanism that matches the type of dispute you expect. Early tax and security planning, before the term sheet hardens, is what separates a deferred structure that pays out cleanly from one that ends in arbitration.
