The Netherlands Authority for Consumers and Markets – known by its Dutch abbreviation Autoriteit Consument en Markt (ACM, the Dutch competition authority) – has materially intensified its enforcement posture in recent cycles. Fines for cartel conduct and market dominance abuse have reached levels that pose direct balance-sheet risk for any international group with Dutch operations. Companies that treated compliance as a background function must reassess that position now.
The ACM's current enforcement drive targets both horizontal cartel arrangements and abusive conduct by dominant undertakings under Netherlands competition legislation. Affected entities include any besloten vennootschap (BV, a Dutch private limited company) or naamloze vennootschap (NV. A Dutch public limited company) operating in concentrated markets, as well as foreign parent groups whose Dutch subsidiaries participate in coordinated pricing or market-sharing. Compliance reviews and internal audit cycles should be completed before the authority's next announced sector inquiry, which industry counsel expect to conclude by the third quarter of 2026.
This alert explains which business categories face the greatest exposure, which penalty thresholds apply, and the five immediate steps international companies should take.
What has changed: ACM enforcement trends and penalty levels
The ACM has adopted a more aggressive enforcement posture across three distinct areas of Netherlands competition legislation: cartel prohibition, abuse of market dominance, and merger notification rules.
On cartel enforcement, the authority has broadened its definition of concerted practice. Information exchanges that stop short of explicit price-fixing agreements now attract scrutiny. The ACM has clarified – through published enforcement guidelines rather than formal rulemaking – that algorithm-mediated price coordination can constitute a cartel under Dutch and EU competition rules. This matters for any platform business or distributor using dynamic pricing software shared with competitors.
On market dominance, the ACM has actively investigated refusal-to-supply conduct and margin-squeeze strategies in digital and infrastructure sectors. A finding of market dominance in the Netherlands does not require a dominant position across the full EU internal market. The ACM applies a national or regional market definition that can cover a single Dutch city or sector segment. Businesses that hold a strong position in any Dutch sub-market should treat that position as potentially dominant for enforcement purposes.
On merger notification, the ACM has tightened its review of transactions that fall below EU-level thresholds but meet Dutch turnover criteria. A transaction may require mandatory notification to the ACM even when no filing is required with the European Commission. Failure to notify before closing – known as gun-jumping – triggers automatic fines regardless of whether the underlying merger is ultimately approved.
Penalty levels under Netherlands competition legislation are calculated as a percentage of annual group turnover, not merely the Dutch subsidiary's revenue. For cartel infringements, maximum fines reach into the tens of millions of euros for mid-size groups. The ACM has demonstrated willingness to impose fines at or near the statutory ceiling in cases involving deliberate concealment. Director-level individuals can face personal fines and, in the most serious cases, referral to the public prosecutor under Dutch criminal procedure.
Appeals against ACM decisions proceed first before the Rechtbank Rotterdam (Rotterdam District Court), which holds specialist jurisdiction over competition cases in the Netherlands. Further appeals on points of law reach the Hoge Raad (Supreme Court of the Netherlands). Litigation timelines in this pathway typically span two to four years. During that period, the ACM fine is payable unless the court grants interim suspension – which Dutch courts grant only in exceptional circumstances.
Who is affected: threshold criteria and business categories
The following categories of international business face the greatest immediate exposure under the current ACM enforcement environment.
- Groups with Dutch subsidiaries registered at the Kamer van Koophandel (KvK, Dutch Chamber of Commerce) in any sector the ACM has designated as a priority – currently including energy, construction, food retail, and digital platforms.
- Companies participating in trade associations, purchasing cooperatives, or industry working groups where commercially sensitive data is shared among competitors.
- Acquirers completing transactions involving Dutch targets that meet national turnover notification thresholds, even where EU-level filing is not required.
- Groups relying on exclusive distribution agreements or selective distribution systems in the Netherlands without a current legal review of their compliance with vertical restraints rules.
- Any undertaking that has applied for – or is considering applying for – the ACM's leniency programme, which allows cartel participants to obtain fine reductions or immunity in exchange for disclosing infringements.
Parent companies incorporated elsewhere in the EU bear direct liability for competition infringements committed by their Dutch operating subsidiaries. The ACM applies an economic unit doctrine: a parent that exercises decisive influence over a Dutch BV or NV is jointly liable for that subsidiary's competition law violations. Even if the parent had no operational knowledge of the conduct.

What to do now: five immediate actions
International companies with Dutch operations should treat the following actions as time-sensitive. Delay increases both the probability of enforcement contact and the size of any eventual penalty.
1. Commission a competition compliance audit. Review all pricing agreements, distribution contracts, and trade association participation for conduct that the ACM is actively targeting. Pay particular attention to information exchanges and algorithm-driven pricing mechanisms. Our competition law practice in the Netherlands can structure an audit that satisfies both Dutch and EU standards.
2. Review merger notification obligations before signing. Any acquisition of Dutch assets or shareholdings should be assessed against ACM notification thresholds at the term-sheet stage. Gun-jumping fines are strict-liability – intent is irrelevant. If thresholds are met, filing must precede closing.
3. Assess dominance risk in all Dutch market segments. Do not assume that a modest overall EU market share insulates a business from ACM dominance findings. Map your position in each Dutch product and geographic sub-market. Where dominance is plausible, audit pricing, supply, and access policies against the ACM's published enforcement priorities.
4. Evaluate leniency programme eligibility if past conduct is uncertain. The ACM's leniency programme offers meaningful fine reductions for the first and second applicants to report a cartel. The window closes once the ACM opens its own investigation. If internal review identifies historical conduct that may qualify as a cartel, legal advice on leniency eligibility should be obtained immediately – before any external disclosure.
5. Prepare for dawn raid response. The ACM conducts unannounced inspections at business premises. Staff should know their rights and obligations during an inspection. A documented dawn-raid protocol – covering who to call, what documents inspectors may access, and how to handle digital searches – reduces the risk of procedural errors that can aggravate a penalty. For groups with cross-border exposure, corporate dispute counsel in the Netherlands should be integrated into the response chain.
