M and A Regulation and Disputes 2026

DENMARK Trends and Developments Contributed by: Thomas Weitemeyer and Jonas Høst, Moalem Weitemeyer

Introduction Denmark continues to be an arbitration-friendly and transaction-driven M&A jurisdiction. In parallel, however, the practical dispute landscape of Danish transactions has evolved markedly. In particular, the interaction between share purchase agreement (SPA) drafting, warranty and indemnity (W&I) insurance and arbitration has reshaped how post-closing disputes are framed, argued and resolved. Two structural developments are especially visible in current Danish deal practice. First, transaction size and deal architecture have grown increasingly complex. Larger transactions, increasingly tailored and sophisticated purchase price mechanics (earn-outs and completion accounts), and the standardisation of W&I insurance have shifted the centre of gravity of post-closing disputes. Ques - tions of liability are no longer primarily concerned with whether a warranty breach can be established in principle. Instead, disputes tend to crystallise around the contractual risk allocation embedded in the SPA and the policy wording: the scope and sufficiency of disclosure, the operation of knowledge qualifiers, the applicable causation standard and, not least, the methodology for quantifying loss. These developments have reinforced arbitration as the natural forum for resolving M&A disputes in Denmark. Arbitration tribunals are increasingly asked to engage in detailed contractual interpretation of SPAs negoti - ated against the backdrop of W&I insurance, includ - ing the alignment (or misalignment) between insured risks and residual seller liability. In practice, this places significant emphasis on precise SPA drafting and on the evidentiary thresholds governing disclosure and knowledge, as arbitral proceedings offer limited scope for expansive disclosure compared to court litigation. Against this background, W&I-related disputes in Danish arbitration often revolve less around factual misconduct and more around interpretative questions: whether a matter was fairly disclosed, whether man - agement knowledge can be imputed to the insured, and how abstract valuation models translate into legally recoverable loss. As a result, the arbitration- friendly nature of the Danish market is increasingly characterised not merely by forum choice, but by

a sophisticated, contract-driven dispute culture in which SPA interpretation and insurance mechanics are central. Secondly, regulatory conditionality is increasingly treated as a standard part of the closing architecture. This is most obvious in FDI/national security screen - ing, which is frequently dealt with as a default condi - tion precedent where the target is active in sensitive sectors and activities, with the effect that timetable engineering and long-stop calibration are now core negotiation items rather than “execution details”. Against that backdrop, four trends stand out in Dan - ish M&A regulation and disputes: (1) the increasing complexity of W&I claims in larger transactions; (2) attempts to bypass SPA arbitration clauses through “side litigation” against target management; (3) increasing friction around “final and binding” audi - tor/expert determinations in earn-out and completion accounts disputes; and (4) FDI screening becoming a standard condition precedent (and a critical-path workstream) in sensitive-sector deals. We will explore these in turn below. Larger Transactions Are Increasing the Complexity, Duration and Evidentiary Burden of W&I Claims W&I insurance is now deeply embedded in Danish pri - vate M&A, particularly in sponsor-backed and cross- border transactions, where the commercial objective is a clean exit for the seller, reduced escrow or hold - back exposure, and a claims process that is concep - tually separated from the seller relationship. In larger and more complex transactions, however, W&I insurance is increasingly shifting disputes away from the substantive question of whether a warranty has been breached and towards evidentiary issues relating to pre-closing knowledge, disclosure, mate - riality, causation and loss. As a result, a product that is intended to simplify risk allocation can, in practice, raise the number of procedural and evidentiary chal - lenges that may become costly for the buyer. In high-value transactions, W&I claims often develop into a three-cornered dynamic between buyer, insurer and (often indirectly) the seller or former management team, where evidentiary access, historical knowledge
