For decades, the architecture of Danish merger control was defined by a simple, predictable gateway: turnover thresholds. If a deal failed to hit the prescribed financial marks, it generally sailed through without antitrust scrutiny. That era of regulatory certainty has now ended. The introduction of a discretionary “call-in power” marks a profound and permanent shift in the Danish competitive landscape. This new authority grants the Danish Competition and Consumer Authority (DCCA) the ability to require notification of any transaction—regardless of its size—if it raises potential competition concerns. For corporate strategists, M&A lawyers, and investors, this development demands a fundamental re-evaluation of risk. A deal that once flew below the radar can now be pulled directly into the DCCA’s spotlight, fundamentally altering deal timelines, costs, and strategic outcomes.
Understanding the Danish Call-In Power: A New Era of Discretionary Oversight
The traditional framework for Danish merger control relied on bright-line rules. Transactions were only subject to mandatory notification if the involved parties exceeded specific domestic or combined turnover thresholds. This system, while clear, created a significant enforcement gap. Deals involving high-value targets with low current turnover—a common profile in the digital economy, biotech, and pharmaceutical sectors—could escape review even if they threatened to significantly impede effective competition.
The new call-in power directly addresses this vulnerability. What is the Danish Competition and Consumer Authority’s call-in power? It is a discretionary tool that allows the DCCA to require parties to submit a full merger notification for a transaction that does not meet the standard mandatory thresholds. The DCCA can exercise this power when it has reasonable grounds to believe that the transaction may restrict competition significantly. This shifts the burden from a purely mechanical, turnover-based assessment to a more substantive, effects-based analysis at the very outset of a deal’s life.
The Strategic Rationale Behind the Reform
Denmark is not acting in a vacuum. This reform aligns Copenhagen with a powerful global trend among competition authorities seeking to capture “killer acquisitions” and strategic deals in innovation-driven markets. The European Commission has aggressively pursued its own call-in mechanism under Article 22 of the EU Merger Regulation, encouraging member states to refer deals that fall below their national thresholds. The United Kingdom operates a robust “share of supply” test and a voluntary regime that effectively allows for significant discretion. Germany has its own transaction value threshold. Denmark’s move solidifies this European consensus: turnover is no longer the sole, or even primary, indicator of a deal’s competitive significance.
Inside the DCCA’s Review Process: Navigating the Standard and Simplified Tracks
Once the DCCA decides to call in a transaction, or if a transaction meets the standard thresholds and is voluntarily notified, the authority proceeds down one of two distinct procedural paths. The choice between the simplified and the standard procedure has profound implications for the depth of the investigation, the burden on the notifying parties, and the involvement of third-party stakeholders.
The Simplified Procedure: Efficiency and Its Limits
The simplified procedure is designed for transactions that are unlikely to raise competition concerns. Under this track, the DCCA places significant reliance on the information provided by the notifying parties themselves. This streamlined approach is predicated on the assumption that the relevant markets are well-understood and that the merger will not create or strengthen a dominant position or significantly impede competition.
However, the simplified procedure does not completely exclude third-party input. The DCCA may separately inform those third parties identified by the notifying party as its main competitors, customers, and suppliers. These entities may be provided with a non-confidential version of the notification and given an opportunity to raise objections. This practice ensures that even under a “light-touch” review, the DCCA maintains a channel for market feedback without initiating a full-scale market investigation.
The Standard Procedure: Deep Dives and Market Investigations
When a transaction proceeds under the standard procedure, the scope and intensity of the DCCA’s review increases dramatically. This path is reserved for deals that present complex competitive issues, such as high market shares, vertical integration concerns, or conglomerate effects.
During this phase, the DCCA actively engages a wide array of other market participants. Competitors, customers, and suppliers are frequently involved in the DCCA’s market investigations. The purpose of this engagement is twofold: first, to precisely define the relevant product and geographic markets; and second, to identify any potential competition concerns arising from the transaction. The DCCA gathers this intelligence through structured questionnaires, direct correspondence, and in-depth meetings or interviews with market players. This is the machinery of antitrust enforcement in action, and it can generate significant information asymmetry between the merging parties and the authority.
The Pivotal Role of Third Parties in Shaping Outcomes
The content of the DCCA’s new framework places a remarkable emphasis on the role of third parties. They are not passive observers; they are active participants whose feedback can make or break a deal. The mechanism begins with a simple publication on the DCCA’s website. When the DCCA receives a draft merger notification, it will normally publish a news item, regardless of the procedural track. This publication invites interested parties to submit comments within a short deadline, typically seven working days. This public window is the first and most critical opportunity for competitors, customers, and suppliers to voice concerns.
Complainants as Strategic Actors
The DCCA’s notice explicitly acknowledges that complainants will from time to time bring a transaction to the authority’s attention. This practice is expected to increase significantly following the introduction of the call-in power. Why? Because the call-in power gives strategic leverage to third parties. A competitor who is unhappy with a deal can now approach the DCCA and argue that the transaction, even if it falls below the thresholds, is anticompetitive. This provides a formal mechanism for rivals to trigger a review that would not otherwise occur.
How does the DCCA consult third parties during its review? Under the standard procedure, the DCCA actively engages competitors, customers, and suppliers through questionnaires and meetings to define markets and assess competitive harm. Under the simplified procedure, it may directly inform key market participants identified by the notifying party. This dual-track approach ensures that the DCCA has multiple avenues for gathering market intelligence, but it also creates significant uncertainty for merging parties, who must anticipate how their customers and rivals will frame the transaction.
Market Testing of Commitments: A Critical Hurdle
Perhaps the most consequential third-party involvement occurs during the remedies phase. When the DCCA identifies competition concerns, the merging parties may offer commitments—such as divestitures or behavioral pledges—to secure approval. The DCCA will normally market test these commitments unless it considers this unnecessary in the circumstances.
This market testing represents a high-stakes moment. The DCCA may conduct direct consultation with relevant third parties, soliciting their detailed views on the sufficiency and practicality of the proposed remedies. Alternatively, the DCCA may publish a notice on its website inviting third-party comments on the commitments. If customers or competitors raise credible objections to the remedies, the DCCA may demand substantial improvements or reject the deal outright. The merging parties must therefore craft commitments that will not only satisfy the DCCA but also withstand the scrutiny of skeptical market participants.
Strategic Implications for M&A in the Danish Market
The introduction of the call-in power and the expanded role of third parties usher in a new strategic reality for dealmakers in Denmark. The most immediate implication is the erosion of jurisdictional certainty. Parties can no longer rely solely on turnover as a safe harbor. Any transaction, regardless of size, now carries a latent antitrust risk.
This requires a proactive approach to antitrust risk assessment. Legal counsel must now conduct a substantive “call-in risk” analysis for every Danish acquisition. This analysis should assess not just market shares, but the strategic importance of the target, the competitive dynamics of the industry, and the likelihood that a third party (a disgruntled competitor or a powerful customer) will bring the deal to the DCCA’s attention.
Furthermore, the seven-day public comment period is a compressed and high-pressure window. Parties must be prepared to engage with third parties before the notification is even filed. Quiet diplomacy and proactive communication with key customers and suppliers can mitigate the risk of a complaint. Drafting a “third-party engagement strategy” should become a standard component of the merger control playbook for Denmark.
Denmark in a European Context: Following the Enforcement Trend
The Danish reform must be viewed as part of a broader European recalibration of merger control powers. The European Commission’s aggressive use of Article 22 referrals to capture deals like Illumina/Grail (before the General Court’s annulment) set a precedent for aggressive jurisdictional expansion. While the Court of Justice has since pushed back on the Commission’s overly broad interpretation, the political and administrative appetite for such powers remains strong among national authorities.
Germany’s introduction of a transaction value threshold (currently set at €400 million) was a direct response to the inability of turnover-based rules to capture high-value tech deals. The UK’s Competition and Markets Authority (CMA) operates a voluntary regime with a powerful “share of supply” test that provides immense flexibility. Denmark’s call-in power is a more targeted version of these tools. It does not automatically capture all sub-threshold deals; it allows the DCCA to act with discretion. This makes it a potentially more surgical, but also less predictable, instrument.
For global firms with multi-jurisdictional deals, the Danish call-in power adds another layer of complexity to the already intricate web of European merger control rules. A deal that clears the EU threshold but falls below the German and Austrian thresholds may still be pulled in by the DCCA. Coordinating strategy across these jurisdictions has never been more critical.
Practical Considerations for Notifying Parties
For those who find themselves subject to a DCCA review, understanding the procedural nuances is essential. The DCCA’s reliance on information provided by the notifying parties in the simplified procedure underscores the importance of a thorough and accurate submission. Any material omission or misrepresentation can undermine the authority’s trust and trigger a full standard procedure review.
In a standard procedure, the merging parties must prepare for extensive data requests. The DCCA’s market investigations can be intrusive and time-consuming. Parties should anticipate requests for customer lists, bidding data, internal strategy documents, and competitor analyses. Managing this process efficiently requires a dedicated internal team and experienced external counsel.
The commitment market test is a particularly delicate phase. The DCCA expects commitments to be clear, effective, and capable of rapid implementation. Parties must be prepared to offer upfront remedies and to engage in constructive dialogue with the DCCA and third parties. The failure to pass the market test can be fatal to a deal.
The quiet introduction of the call-in power and the formalization of third-party consultation mechanisms have fundamentally reshaped the Danish merger control environment. The question for dealmakers is no longer simply, “Does this transaction meet the filing thresholds?” It is now, “Could this transaction be perceived as harming competition in Denmark?” The DCCA has armed itself with the tools to say “yes” to that question, even for deals that would have once passed entirely unnoticed. For any company active in the Danish market, the time to prepare for this new regime is now—before a transaction is signed, not after it is announced.
