Nordic Merger Cooperation

1. Introduction

Nordic merger cooperation refers to the cooperation among the Nordic competition authorities—particularly those of Denmark, Finland, Iceland, Norway and Sweden—in reviewing mergers and concentrations that have effects across more than one Nordic market.

The Nordic countries have relatively small and highly interconnected economies. A transaction may therefore affect competition in several Nordic countries simultaneously, even when the parties are headquartered in only one country. Cooperation is consequently important for:

• exchanging information and economic analysis;
• coordinating merger investigations;
• avoiding unnecessary duplication;
• assessing cross-border markets consistently;
• coordinating remedies; and
• identifying transactions whose competitive effects extend beyond national borders.

The cooperation operates alongside the EU Merger Regulation (EUMR) for transactions falling within EU jurisdiction and the individual national merger-control regimes of the Nordic countries.

2. The Nordic Competition Authorities

The principal authorities are:

Nordic cooperation does not create a single Nordic merger authority. Each authority retains its national statutory jurisdiction.

Instead, cooperation allows authorities to coordinate their respective investigations.

3. Why Nordic Merger Cooperation Matters

Nordic economies frequently have:

• common suppliers;
• cross-border retail markets;
• integrated logistics systems;
• common telecommunications infrastructure;
• energy interconnections;
• banking and financial services;
• construction and infrastructure suppliers;
• pharmaceutical markets;
• digital platforms; and
• multinational Nordic corporate groups.

A merger between two businesses may consequently produce:

Denmark → Sweden → Norway → Finland → Iceland

effects simultaneously.

For example, if two major construction-material suppliers merge, the transaction may affect procurement and prices throughout several Nordic countries even though the parties have separate subsidiaries in each jurisdiction.

4. Legal Basis

Nordic merger cooperation is supported by several layers of competition law.

A. National merger-control laws

Each Nordic state applies its own merger-control legislation.

The national authorities examine matters such as:

• jurisdiction;
• notification thresholds;
• relevant markets;
• dominance;
• unilateral effects;
• coordinated effects;
• efficiencies;
• remedies; and
• implementation risks.

B. EU competition law

Denmark, Finland and Sweden are EU Member States.

Where the transaction falls within the jurisdiction of the EU Merger Regulation, the European Commission generally conducts the principal merger review.

Norway and Iceland are outside the EU but participate in the EEA framework, creating additional interaction between national and European competition rules.

C. Nordic cooperation

The Nordic authorities have developed institutional cooperation mechanisms permitting exchange of experience and coordination in cross-border competition matters.

This is particularly important where the same transaction is reviewed independently under multiple national laws.

5. Main Forms of Cooperation

A. Information Exchange

Authorities may exchange relevant information concerning:

• market definition;
• competitors;
• customers;
• market shares;
• internal documents;
• economic evidence;
• theories of harm; and
• proposed remedies.

Information exchange remains subject to applicable confidentiality and procedural rules.

B. Parallel Investigations

A transaction may require parallel national investigations.

For example:

Transaction

↓

Danish jurisdiction

↓

Swedish jurisdiction

↓

Norwegian jurisdiction

↓

Common competitive concerns

↓

Inter-authority cooperation

↓

Coordinated investigation

This avoids authorities developing completely inconsistent understandings of the same market.

C. Coordinated Market Definition

Suppose a merger involves a Nordic-wide market for a particular industrial product.

Authorities may examine:

1. geographic scope;
2. customer substitution;
3. supplier substitution;
4. imports;
5. transportation costs;
6. market shares;
7. entry barriers; and
8. competitive constraints.

Although each authority ultimately applies its own national law, cooperation can promote consistency in the economic analysis.

6. Cross-Border Nordic Markets

Certain industries particularly encourage Nordic cooperation.

Energy

Nordic electricity markets are highly interconnected.

A merger involving electricity generation, transmission-related services or energy trading may therefore have effects across borders.

Telecommunications

Telecommunications operators frequently operate in multiple Nordic jurisdictions.

Issues may include:

• network access;
• spectrum;
• infrastructure;
• roaming;
• mobile services;
• broadband;
• wholesale markets.

Banking

Nordic financial institutions often operate across several countries.

Merger analysis can therefore involve:

• retail banking;
• corporate banking;
• payment systems;
• mortgages;
• insurance;
• investment services.

Retail

Retail chains may purchase goods centrally and operate stores across multiple Nordic states.

This can create cross-border purchasing-power and supplier-foreclosure issues.

7. Merger Theories of Harm in Nordic Cooperation

A. Horizontal Effects

Where competitors merge, authorities may examine:

• market shares;
• concentration;
• closeness of competition;
• unilateral price effects;
• loss of innovation;
• capacity reduction;
• customer switching;
• coordinated effects.

B. Vertical Effects

A vertically integrated merger may create incentives to:

• foreclose competitors;
• restrict access;
• raise rivals' costs;
• discriminate against competing downstream firms;
• deny interoperability.

Cross-border cooperation is particularly useful where the upstream and downstream markets operate across different Nordic countries.

C. Conglomerate Effects

A diversified Nordic company acquiring a business in an adjacent market could potentially use:

• bundling;
• tying;
• loyalty arrangements;
• portfolio effects;
• access to data; or
• control of infrastructure

to weaken competitors.

8. Remedies

Nordic merger cooperation can also concern remedies.

Structural remedies

Examples include:

• divestiture of businesses;
• sale of assets;
• disposal of facilities;
• transfer of customer contracts.

Behavioural remedies

Examples include:

• access commitments;
• non-discrimination obligations;
• licensing;
• interoperability;
• supply commitments;
• firewalls.

A cross-border remedy may need to operate consistently in several Nordic jurisdictions.

9. Six Important Case Laws / Decisions

Because Nordic merger cooperation is an institutional practice rather than a single statutory doctrine, relevant authorities are often found in merger decisions involving Nordic markets and cross-border transactions.

1. Telia / Sonera

The Telia–Sonera transaction involved two major Nordic telecommunications operators and became one of the significant historical examples of consolidation in Nordic telecommunications.

Importance

The transaction demonstrated the importance of examining:

• telecommunications infrastructure;
• national telecom markets;
• cross-border operations;
• network effects;
• market concentration.

It also illustrates why a transaction involving companies operating across several Nordic states cannot always be assessed solely through the lens of a single national market.

2. Telia / Telenor

The proposed combination between Telia and Telenor was a major Nordic telecommunications transaction.

Competition concerns

The authorities examined concerns associated with combining major telecommunications businesses, including:

• mobile telecommunications;
• fixed-line services;
• infrastructure;
• competition in Nordic markets.

The transaction ultimately did not proceed.

Significance

The matter demonstrates that Nordic merger cooperation is particularly relevant when a transaction involves major infrastructure operators whose activities span several Nordic countries.

3. Statoil / Norsk Hydro

The combination of Statoil and Norsk Hydro's oil and gas activities represented a major Norwegian energy-sector concentration.

Competition issues

The transaction required consideration of:

• upstream petroleum activities;
• downstream activities;
• market concentration;
• infrastructure;
• access;
• energy-sector competition.

Nordic relevance

Energy markets are inherently cross-border in the Nordic region, making cooperation and information exchange especially important when assessing large energy transactions.

4. ICA / Dansk Supermarked-related Nordic Retail Transactions

Nordic retail consolidation has repeatedly raised competition concerns because large retailers may operate across national borders while purchasing from common suppliers.

Relevant issues

Authorities can examine:

• purchasing power;
• supplier dependence;
• geographic market definition;
• local retail competition;
• distribution networks;
• barriers to entry.

Significance

Retail illustrates the distinction between national retail markets and increasingly integrated Nordic procurement markets.

5. SAS / Widerøe

The proposed acquisition of Widerøe by SAS raised important issues concerning competition in Nordic aviation.

Relevant markets

The analysis could involve:

• airline routes;
• airport access;
• passenger services;
• connecting networks;
• frequency;
• capacity;
• competitive alternatives.

Nordic significance

Air transport demonstrates how a transaction can affect both national markets and cross-border connectivity.

6. Telia / Bonnier Broadcasting

The acquisition of Bonnier Broadcasting by Telia was an important Nordic media transaction.

Competition concerns

The transaction combined:

• telecommunications infrastructure;
• television content;
• broadcasting;
• distribution;
• digital media.

The transaction therefore raised issues concerning vertical integration and the relationship between content and distribution.

Significance

It illustrates the increasing importance of examining digital convergence and vertical foreclosure in Nordic merger control.

10. Nordic Cooperation and the EU Merger Regulation

A crucial distinction must be made between Nordic cooperation and European Commission merger control.

Where the EU Merger Regulation applies, the European Commission may have exclusive jurisdiction over the concentration.

The Nordic authorities nevertheless remain relevant in:

• providing national market information;
• contributing local market knowledge;
• identifying national competitive conditions;
• participating through European competition-law mechanisms.

Thus:

Large EU-dimension merger

→ European Commission jurisdiction

→ Nordic market information

→ National competition authorities

→ Coordinated economic assessment

11. Nordic Cooperation and Norway/Iceland

Norway and Iceland require special consideration because they are not EU Member States.

Their competition authorities operate under their respective national legislation while being connected to the wider European competition framework through the EEA.

Consequently, a transaction affecting:

• Sweden,
• Denmark,
• Finland,
• Norway, and
• Iceland

may require consideration of several overlapping legal regimes.

12. Role of the Nordic Competition Authorities

Nordic cooperation serves several practical purposes.

1. Consistency

Authorities can reduce unnecessary divergence in economic analysis.

2. Efficiency

Parallel investigations can be coordinated.

3. Expertise

An authority with greater expertise concerning a particular market can contribute knowledge to other authorities.

4. Evidence

Cross-border information can help authorities understand the actual competitive structure.

5. Remedies

Authorities can consider whether remedies need to operate across multiple Nordic countries.

13. Confidentiality and Procedural Safeguards

Information exchange is not unrestricted.

Authorities must consider:

• confidentiality;
• legal privilege where applicable;
• business secrets;
• procedural rights;
• statutory information-sharing powers;
• rights of the merging parties.

Therefore, Nordic cooperation does not mean that confidential commercial information automatically becomes publicly available.

14. Economic Analysis

Modern Nordic merger review increasingly relies on economic evidence.

Important tools include:

HHI

The Herfindahl-Hirschman Index may be used to assess concentration.

Diversion ratios

These help determine how closely merging products compete.

UPP analysis

Upward Pricing Pressure can be relevant in differentiated-product mergers.

Critical-loss analysis

Authorities may examine whether a hypothetical price increase would be profitable.

Entry analysis

Authorities examine:

• cost of entry;
• regulatory barriers;
• access to infrastructure;
• economies of scale;
• network effects.

15. Digital and Technology Mergers

Nordic cooperation has increasing relevance to digital markets.

Potential concerns include:

• platform dominance;
• data concentration;
• interoperability;
• API access;
• self-preferencing;
• network effects;
• ecosystem foreclosure;
• digital advertising;
• cloud services;
• fintech platforms.

A digital platform operating throughout the Nordic region can make traditional national-market analysis more complicated.

16. Nordic Merger Cooperation vs. Nordic Merger Control

The distinction is fundamental.

Cooperation ≠ a single Nordic merger regime.

17. Key Challenges

A. Different National Thresholds

Each jurisdiction may have different notification rules.

B. Different Market Structures

A market may be competitive in Sweden but concentrated in Norway.

C. Different Remedies

One authority may consider divestiture while another considers access commitments.

D. Confidentiality

Information sharing must comply with applicable legal safeguards.

E. EU/EEA Interaction

Transactions can involve overlapping European and national jurisdictional questions.

F. Digital Markets

Geographic boundaries are increasingly difficult to define.

19. Key Takeaways

1. Nordic merger cooperation is a coordination framework, not a single Nordic merger authority.
2. Denmark, Finland, Iceland, Norway and Sweden have their own competition authorities and merger-control regimes.
3. Cross-border cooperation is especially important in telecommunications, energy, banking, retail, transport and digital markets.
4. Information exchange and coordinated economic analysis are central components.
5. EU Merger Regulation jurisdiction must be distinguished from national Nordic merger jurisdiction.
6. Norway and Iceland introduce additional EEA considerations.
7. Remedies may require coordination where competitive effects span multiple Nordic states.
8. Digitalisation makes Nordic cross-border merger analysis increasingly important.
9. Confidentiality and procedural rights remain important limitations on information exchange.
10. Major Nordic transactions such as Telia–Sonera, Telia–Telenor, Statoil–Norsk Hydro, SAS–Widerøe and Telia–Bonnier Broadcasting illustrate different dimensions of cross-border merger assessment.

Conclusion

Nordic merger cooperation is best understood as a mechanism for coordinated enforcement among closely interconnected national competition regimes. Its importance arises from the economic integration of the Nordic countries, where a merger affecting one national market may simultaneously influence competition, suppliers, infrastructure and consumers throughout the wider Nordic region. The framework therefore facilitates information sharing, consistent economic assessment and coordinated consideration of remedies while preserving the separate statutory authority of each national competition agency.
