Post-Closing Disputes after Dutch Acquisitions

Warranty claims, earn-outs, completion accounts, restrictive covenants and shareholder conflict after closing

Post-closing disputes after Dutch acquisitions are disputes that arise after completion of an M&A transaction. They often concern warranty claims, indemnities, earn-outs, completion accounts, locked box leakage, restrictive covenants, seller involvement, management arrangements or shareholder conflicts.

For foreign buyers, private equity funds, strategic investors and international counsel, post-closing disputes in the Netherlands are rarely just litigation issues. They usually begin in the transaction documents: the SPA, disclosure letter, earn-out schedule, completion accounts mechanism, vendor loan agreement, shareholders’ agreement, management participation documents or restrictive covenants.

A Dutch acquisition does not end at closing. The way the deal was documented before signing often determines whether a post-closing disagreement can be resolved commercially or becomes a formal dispute.

This article is part of the M&A Insights series on Dutch deal practice and is relevant for foreign buyers, sellers, PE funds, VC investors, management teams and international counsel involved in Dutch acquisitions.

Why post-closing disputes arise

Post-closing disputes usually arise because the buyer and seller continue to have financial or operational connections after completion.

The seller may remain liable under warranties or indemnities. The purchase price may still be adjusted through completion accounts. An earn-out may depend on future performance. A vendor loan may remain unpaid. The seller may continue as manager, consultant or minority shareholder. The shareholders’ agreement may continue to regulate governance after closing.

These connections are often commercially useful. They can bridge valuation gaps, protect against known risks or support business continuity. But they also create points of friction.

The key question is whether the transaction documents make those frictions manageable.

Warranty claims

Warranty claims are one of the most common sources of post-closing disputes.

A buyer may allege that the target business was not as warranted at signing or closing. Typical issues include financial statements, tax, contracts, employment, litigation, compliance, IP, data protection, permits, debt, customers, suppliers or undisclosed liabilities.

For foreign buyers, Dutch warranty claims require careful attention to the SPA wording, disclosure, knowledge qualifiers, caps, baskets, de minimis thresholds, limitation periods and claims procedure. A warranty claim is not only about whether something went wrong. It is also about whether the buyer can prove a breach within the contractual framework.

For sellers, disclosure is critical. If a matter has been properly disclosed, the buyer may have difficulty bringing a warranty claim based on that issue.

Indemnity claims

Indemnities are different from general warranties. They allocate a specific known risk.

A buyer may bring an indemnity claim where a tax audit, pending litigation, environmental issue, customer dispute or other identified matter results in loss after closing.

Indemnity disputes often focus on scope. Was the loss within the indemnified risk? Are adviser costs included? Are penalties, interest or tax effects covered? Does the general liability cap apply? Is there a specific cap or time limit? Has the buyer mitigated loss?

The SPA should clearly state how indemnities interact with disclosure, W&I insurance, purchase price adjustments and no double recovery.

Earn-out disputes

Earn-outs are a frequent source of post-closing conflict because they depend on the future performance of the business after control has passed to the buyer.

A seller may believe that the buyer has not operated the business in a way that allows the earn-out to be achieved. A buyer may argue that the earn-out targets were not met under the agreed formula. Disputes often concern revenue recognition, EBITDA adjustments, customer allocation, group costs, accounting policies, business integration, budget decisions and management changes.

For foreign buyers, the main lesson is that earn-outs must be drafted with operational reality in mind. If the buyer intends to integrate the Dutch target into a wider group, the earn-out mechanism must explain how group integration affects performance measurement.

For sellers, operational covenants and information rights during the earn-out period are often essential.

Completion accounts and purchase price adjustments

Completion accounts can lead to technical but financially significant disputes.

The parties may disagree on cash, debt, working capital, normalised working capital, debt-like items, transaction costs, tax liabilities, intercompany balances or accounting policies. A small drafting difference can have a large purchase price effect.

A well-drafted SPA should include clear definitions, accounting hierarchy, illustrative calculations, timing for review, objection procedures and expert determination mechanics.

Foreign buyers should not assume that a completion accounts dispute is only an accounting matter. The legal drafting determines what the accountant or expert is allowed to decide.

Locked box leakage

In locked box transactions, disputes often concern leakage.

The buyer may claim that value leaked from the target to the seller or related parties between the locked box date and closing. Examples include dividends, management fees, related party payments, bonuses, transaction expenses, intercompany settlements or non-arm’s length arrangements.

The seller will usually point to permitted leakage or ordinary course arrangements.

The SPA should therefore clearly define leakage, permitted leakage, notification obligations and remedies. If the definitions are too generic, locked box certainty can quickly turn into a post-closing dispute.

Restrictive covenants

Restrictive covenants also create post-closing disputes.

A buyer may allege that the seller breached a non-compete, non-solicitation, non-hire or confidentiality covenant. This is especially relevant where the seller was central to customer relationships, know-how, management or business development.

Disputes may concern whether the restricted activity falls within the business sold, whether the covenant is proportionate, whether the relevant customer or employee is protected, and whether the seller acted directly or indirectly through another entity.

Seller involvement after closing

Many Dutch acquisitions involve continued seller involvement. A founder may stay on as managing director, consultant or minority shareholder. Management may roll over equity. The seller may assist with transition, customer handover or earn-out performance.

This can be commercially useful, but legally sensitive. The seller may wear several hats at once: former owner, manager, earn-out beneficiary, lender under a vendor loan, minority shareholder or consultant.

Post-closing disputes often arise when these roles are not clearly separated. The documents should explain the seller’s duties, authority, information rights, restrictions, compensation, termination rights and consequences of breach.

Shareholder conflicts after acquisition

If the seller or management remains a shareholder after closing, disputes may shift from SPA claims to shareholder governance.

Issues may concern reserved matters, information rights, board seats, deadlock, drag-along, tag-along, leaver provisions, minority rights, dividend policy, funding obligations or exit timing.

For foreign investors, this is a common Dutch implementation issue. The SPA may close the acquisition, but the shareholders’ agreement governs the continuing relationship. If those documents are not aligned, the dispute may become more complicated.

Evidence and process

Post-closing disputes are often won or lost on evidence.

Buyers should preserve due diligence materials, disclosure records, closing deliverables, management accounts, correspondence, board minutes, integration decisions and claim notices. Sellers should preserve disclosure materials, negotiation history, responses to due diligence questions, closing records and evidence of buyer knowledge.

The claims procedure in the SPA matters. Missing a notice deadline, failing to specify the claim properly or not following expert determination procedures can weaken an otherwise legitimate claim.

Practical conclusion

Post-closing disputes after Dutch acquisitions are usually not isolated events. They are the result of how risk was allocated before signing and how the relationship was managed after closing.

For buyers, the focus should be on preserving claims, following contractual procedures and linking the dispute to the SPA or related documents. For sellers, the focus should be on disclosure, liability limitations, claim defence and preventing broad allegations from becoming open-ended exposure.

A well-drafted Dutch transaction package does not eliminate every dispute. But it makes disputes more predictable, more evidence-based and easier to resolve.

FAQ

What are common post-closing disputes in Dutch M&A?
Common disputes concern warranty claims, indemnities, earn-outs, completion accounts, locked box leakage, restrictive covenants, vendor loans and shareholder conflicts.

Are warranty claims easy to bring after a Dutch acquisition?
That depends on the SPA. The buyer must show a warranty breach and comply with caps, thresholds, limitation periods, disclosure rules and claim procedures.

Why do earn-outs often lead to disputes?
Because the buyer controls the business after closing while the seller remains financially interested in future performance.

Can completion accounts disputes be referred to an expert?
Yes, if the SPA provides for expert determination. The scope of the expert’s role should be clearly defined.

How can parties reduce post-closing disputes?
By drafting clear SPA provisions, defining claims procedures, aligning related documents, preserving evidence and addressing seller involvement after closing.
