Merger control discipline protects the transaction before closing
Merger control affects more than the filing itself. This note sets out how notification, standstill and gun-jumping risk should shape the SPA, the clean-team protocol and the parties' conduct between signing and closing.
Control and notification come before the timetable
Dutch merger control applies to concentrations that meet the statutory conditions, including turnover thresholds. Under the Dutch Competition Act (Mededingingswet), a transaction may require notification to the ACM before it is implemented. A concentration commonly arises where an undertaking acquires sole or joint control, so the legal analysis must look beyond the percentage of shares acquired to the rights that confer decisive influence.
The assessment should begin while the transaction structure is still flexible. Share acquisitions, asset acquisitions, joint ventures and arrangements involving veto rights may all require a control analysis. Where the transaction has a European dimension or affects more than one jurisdiction, EUMR referral routes and parallel national filing requirements need to be considered as part of the same workstream.
The filing assessment should not be left to the end of legal due diligence. It informs whether approval is a condition precedent, the appropriate long-stop date, the cooperation covenant, the allocation of remedy risk and the communications timetable. The agreement should also specify who prepares the notification, which party controls external communications, how the parties provide information and how the costs of a remedy or delay are allocated.
Standstill is an operating restriction
A notifiable concentration may not be implemented while the statutory standstill obligation applies. The standstill obligation is not confined to the formal execution of a share transfer. It also requires care where the buyer and seller seek to organise the business, exchange information or agree operational decisions before closing.
The legitimate purpose of pre-closing covenants is to preserve the value of the target. The seller may agree not to make exceptional disposals, amend key contracts or change the business outside the ordinary course without the buyer's consent. Those covenants need defined thresholds and limited subjects, so that they protect value without giving the buyer the ability to direct day-to-day commercial conduct.
The distinction is fact-sensitive. Rights over ordinary-course pricing, customer terms, senior appointments, operating budgets or a broad range of commercial contracts can move from protection to influence. The SPA should therefore explain the permitted consultation process, preserve the seller's operational responsibility until completion and identify decisions that need regulatory advice before either party acts.
Sensitive information exchange calls for a clean team
Pre-closing information exchange can be necessary for financing, integration planning and regulatory filings. It can also create risk where the parties are actual or potential competitors. The cartel prohibition covers agreements and concerted practices that restrict competition, which is a separate concern from the merger-control standstill rule.
A clean-team protocol gives the process an operational boundary. It identifies the categories of competitively sensitive information, the limited persons who may receive it, the purpose for which it may be used, the systems in which it is held and the rules for reporting aggregated outputs to the transaction team. Customer-specific pricing, future strategy, margins and commercially sensitive pipeline information commonly require particular controls.
The protocol should be attached to the transaction process rather than kept as a generic compliance document. It should name the clean-team members, require confidentiality undertakings, set out the escalation route for difficult requests and preserve an audit trail of access and output. The data room, Q&A process, management presentations and integration workstreams should all use the same categories and permissions.
Integration planning can proceed within boundaries
The parties may plan for a lawful post-closing integration while maintaining their independence before clearance and completion. Planning can address Day One governance, systems migration, employee communications, customer notices and transitional services. It must not amount to implementing the concentration early or coordinating current competitive behaviour.
A pre-closing conduct list is useful because it converts the legal boundary into instructions that management can apply. Permitted activity ordinarily includes preparing non-binding plans, gathering information through the clean-team process and arranging completion deliverables. Restricted activity includes directing the target's ordinary-course operations, exercising broad buyer veto rights, sharing sensitive information outside the agreed protocol and presenting the parties to the market as already integrated.
Competition authorities pay attention to gun jumping and to new theories of harm. That is a reason for disciplined transaction planning, not for assuming that clearance will be problematic. The review should also consider transactions below ordinary thresholds where a referral or a sector-specific rule may be relevant.
The SPA is the control document
The merger-control condition should state the relevant approvals with enough flexibility to accommodate changes in the authority or process. It should allocate responsibility for preparing the filing, responding to information requests and deciding whether to offer commitments. Where the commercial agreement permits termination after a long-stop date, the parties should also decide whether a pending remedy discussion, appeal or referral justifies an extension.
The clean-team protocol and pre-closing conduct rules should be treated as closing documents in their own right. They guide the people most likely to encounter the issue: executives planning integration, commercial teams answering diligence questions and finance staff preparing synergy analysis. A short document with clear owners is more reliable than an abstract statement that the parties will comply with applicable law.
We advise clients to agree this framework at signing. It gives the transaction a clear route through notification and standstill, while preserving the operational preparation needed for an orderly closing.
Points that decide the outcome
- The Dutch Competition Act can require notification and clearance before a concentration is implemented.
- The control analysis examines decisive influence, not only the percentage of shares acquired.
- The SPA should connect filing risk to conditions precedent, the long-stop date, cooperation obligations and remedy allocation.
- Standstill permits value-protection covenants but does not permit the buyer to direct the target's ordinary-course business.
- The cartel prohibition makes the exchange of competitively sensitive information a separate competition-law concern.
- A clean-team protocol and a pre-closing conduct list turn legal restrictions into workable transaction controls.
