Germany 2026: Merger Control & Clearance for Cross‑border M&A, a Practical Guide for Buyers

Cross-border buyers targeting German companies face one of Europe’s most active merger control regimes, and the landscape has only grown more complex heading into the second half of 2026. Merger control Germany is governed by the Act against Restraints of Competition (GWB), enforced by the Bundeskartellamt, the Federal Cartel Office, which reviews well over a thousand concentrations each year. Alongside antitrust clearance, non-EU acquirers must now navigate an increasingly assertive foreign direct investment (FDI) screening regime administered by the Federal Ministry for Economic Affairs and Climate Action (BMWK).

This guide provides general counsel, private-equity teams and strategic buyers with a transaction-ready playbook: filing triggers, required documents, statutory timelines, FDI interaction, remedies negotiation tactics and a client-ready M&A regulatory checklist designed to keep deal timetables on track.

Executive Summary: Merger Control Germany, Clearance Decision Checklist

Before engaging external counsel or drafting an SPA, deal teams should run through the following quick-reference decision points. If the answer to any of the first three questions is “yes,” a Bundeskartellamt notification is very likely required.

• Combined worldwide turnover. Do the participating undertakings together generate combined worldwide turnover exceeding EUR 500 million?
• Domestic turnover, first undertaking. Does at least one participating undertaking generate domestic turnover in Germany exceeding EUR 50 million?
• Domestic turnover, second undertaking. Does at least one other participating undertaking generate domestic turnover in Germany exceeding EUR 17.5 million?
• De minimis exception. Is the target an independent undertaking with worldwide turnover below EUR 10 million? If so, the transaction may be exempt.
• Transaction-value threshold. Even if turnover thresholds are not met, does the transaction value exceed EUR 400 million and is the target significantly active in Germany? If yes, filing may still be triggered under Section 35(1a) GWB.
• FDI screening. Is the buyer domiciled outside the EU/EFTA, and does the target operate in a sensitive sector (energy, critical infrastructure, defence, telecoms, AI or dual-use technology)?
• EU-level jurisdiction. Do the parties’ combined turnovers meet the EU Merger Regulation (EUMR) thresholds, potentially giving the European Commission exclusive competence?

Outcome scenarios: The vast majority of notified concentrations in Germany are cleared in Phase I without conditions. A smaller proportion proceed to an in-depth Phase II investigation, where the Bundeskartellamt may clear unconditionally, clear subject to remedies, or prohibit the transaction.

What Is Covered: Legal Framework and Key Actors in Antitrust Germany

Germany’s merger control rules sit primarily within Part 3 of the GWB. The Bundeskartellamt is the competent national authority and maintains a mandatory, suspensory pre-merger notification regime, meaning the parties must not close the deal until clearance is obtained or the statutory review period expires. The regime applies to “concentrations” as defined in Section 37 GWB and is triggered when certain turnover thresholds are met.

Since 2024, amendments to the GWB have refined the transaction-value test introduced in the 11th GWB Amendment, sharpened the Bundeskartellamt’s investigative tools and aligned aspects of German antitrust Germany enforcement with the EU’s Digital Markets Act framework. Industry observers expect further procedural adjustments as the 12th GWB Amendment continues its legislative passage.

Scope, What Is a “Concentration”?

Under Section 37 GWB, a notifiable concentration includes the acquisition of all or a substantial part of another undertaking’s assets, the acquisition of direct or indirect control, the acquisition of shares reaching 25 % or 50 % of the voting rights, and any other transaction that confers a competitively significant influence over another undertaking. Joint ventures that perform all the functions of an autonomous economic entity on a lasting basis are also caught.

When the European Commission May Pre-empt

Under the EUMR (Council Regulation (EC) No 139/2004), the European Commission has exclusive jurisdiction if the merging parties meet certain EU-wide turnover thresholds, specifically, combined aggregate worldwide turnover exceeding EUR 5 billion and individual EU-wide turnover for at least two parties exceeding EUR 250 million, unless each party achieves more than two-thirds of its EU-wide turnover in one and the same Member State. Where EC jurisdiction applies, German merger control rules generally do not. However, Germany may request a referral under Article 9 EUMR if the concentration threatens to significantly affect competition in a distinct market within Germany.

Filing Triggers and Merger Filing Thresholds: How to Decide Whether to Notify the Bundeskartellamt

The Bundeskartellamt notification obligation is mandatory whenever a concentration meets the thresholds set out in Section 35 GWB. There is no filing fee. The obligation applies regardless of the nationality or domicile of the acquirer, cross-border M&A Germany transactions are treated identically to purely domestic deals.

Turnover Thresholds Explained

Under Section 35(1) GWB, a concentration must be notified if all three of the following cumulative conditions are satisfied:

In addition, Section 35(1a) GWB introduces a transaction-value test: even if the EUR 17.5 million domestic turnover threshold is not met by the second undertaking, a filing obligation arises if the value of the consideration exceeds EUR 400 million and the target undertaking is significantly active in Germany. This provision targets acquisitions of high-value start-ups or IP-rich companies that do not yet generate significant revenue.

Exceptions and Carve-outs

A concentration is exempt from notification under the de minimis rule (Section 35(2) GWB) if the target is an independent undertaking with worldwide turnover not exceeding EUR 10 million. The Bundeskartellamt has no discretion to extend this, the exemption is automatic. Certain intra-group restructurings and temporary acquisitions by financial institutions or insurance companies (held solely for resale within one year) are also carved out.

Worked Examples

• Strategic acquisition of a German Mittelstand company. A Japanese industrial group (worldwide turnover EUR 8 billion, German turnover EUR 120 million) acquires 100 % of a German mechanical-engineering firm (worldwide turnover EUR 60 million, German turnover EUR 45 million). All three Section 35(1) thresholds are met, notification is mandatory.
• Acquisition of a German deep-tech start-up. A US private-equity fund acquires a Berlin-based AI start-up with worldwide turnover of only EUR 3 million, but the deal value is EUR 650 million. Even though the EUR 17.5 million target turnover threshold is not met, the transaction-value test under Section 35(1a) is triggered, notification is required.
• De minimis carve-out. A French conglomerate acquires a small German subsidiary with worldwide turnover of EUR 8 million. The de minimis exemption under Section 35(2) applies, no filing required.

Notification Process and Required Documents for Merger Clearance Germany

Once the filing obligation is confirmed, the deal team should move promptly to prepare and submit the notification. Unlike some jurisdictions, Germany does not use a prescribed form, notifications are submitted as a written document (in German) accompanied by supporting materials.

Form and Content of the Notification

The Bundeskartellamt expects the notification to contain, at a minimum:

1. Description of the concentration: Nature and structure of the transaction (share deal, asset deal, joint venture), identity of all participating undertakings, and the resulting ownership or control structure.
2. Turnover data: Worldwide and domestic turnover for each participating undertaking for the most recent financial year, broken down to show that the filing thresholds are met.
3. Market definitions: The relevant product and geographic markets affected by the concentration, with supporting data on market shares, competitors, customers and barriers to entry.
4. Competitive assessment: An explanation of why, in the filing parties’ view, the concentration does not significantly impede effective competition (or, if it does, why remedies are being offered).
5. Vertical and conglomerate effects: Where relevant, an analysis of vertical relationships and portfolio effects.

Practical tip: Pre-notification discussions with the Bundeskartellamt case team are strongly recommended for complex transactions. These informal contacts allow the parties to agree on the scope of market definitions and the level of detail required, thereby reducing the risk of the authority declaring the notification incomplete.

Supporting Materials (Market Data, Contracts)

• Copies of the transaction agreements (SPA, SHA, JV agreements)
• Most recent annual reports and audited financial statements for each party
• Internal board presentations and strategy documents relating to the transaction (the Bundeskartellamt may request these during review)
• Market studies, industry reports and customer/competitor lists for the relevant markets

Confidentiality Considerations

Filing parties may request confidential treatment for business secrets under Section 43(3) GWB. The Bundeskartellamt publishes information about notified concentrations in its online database, but commercially sensitive data is redacted upon request. Deal teams should flag confidential passages clearly in the notification itself to avoid inadvertent disclosure.

Timeline, Phases and Practical Timing Risks in Merger Control Germany

Germany’s merger clearance process is divided into two phases, each with a statutory clock. The suspension obligation under Section 41(1) GWB means that closing before clearance, or before the statutory period expires without a prohibition, is prohibited and constitutes a gun-jumping violation, which can attract fines of up to 10 % of annual group turnover.

Typical Durations and Examples

How to Compress Timelines (Remedies Negotiations, Commitments)

• Pre-notification engagement. Starting informal discussions with the case team 4–6 weeks before the formal filing can resolve market-definition disputes early and accelerate Phase I.
• Upfront remedy offers. If competitive concerns are foreseeable, offering structural remedies with the notification (or early in Phase I) may enable Phase I clearance with conditions, avoiding Phase II entirely.
• Parallel workstreams. Where FDI screening or EC referral requests are also in play, running these workstreams concurrently, rather than sequentially, can save two to three months on the overall deal timetable.
• Clean-team and data-room discipline. Maintaining well-organised market data and internal documents reduces the risk of information requests that pause the statutory clock.

FDI Screening Germany and Its Interaction with Merger Control

Since the tightening of Germany’s Foreign Trade and Payments Act (Außenwirtschaftsgesetz, AWG) and the Foreign Trade and Payments Ordinance (Außenwirtschaftsverordnung, AWV) in successive rounds between 2020 and 2025, FDI screening Germany has become a major additional clearance hurdle for non-EU/EFTA buyers. The BMWK has the power to review, impose conditions on or prohibit acquisitions of German businesses by non-EU/EFTA investors where national security or public order is at risk.

Which Investments Trigger FDI Screening?

Two regimes run in parallel under the AWV:

• Cross-sector screening (Section 55 AWV): Applies to acquisitions by non-EU/EFTA investors of 25 % or more of voting rights in any German company. The BMWK may open a review within two months of becoming aware of the transaction.
• Sector-specific screening (Section 60 AWV): Applies to acquisitions of 10 % or more of voting rights in companies active in particularly sensitive sectors, including defence, critical infrastructure (energy, water, telecoms, IT security), hospitals, media, certain artificial-intelligence applications, cloud computing, dual-use technology and semiconductor manufacturing. A mandatory filing obligation exists for these sector-specific transactions.

The likely practical effect of recent regulatory trends is that the scope of “sensitive sectors” will continue to expand. Legislative proposals under discussion in 2026 suggest that supply-chain-critical raw materials and advanced battery technology may soon be added.

Parallel Reviews and Sequencing

FDI screening and Bundeskartellamt merger control are legally independent proceedings. There is no statutory requirement to complete one before the other. In practice, however, deal teams should be aware that:

• The FDI review timeline is less predictable than the merger control clock. Cross-sector reviews can extend to four months (with a possible further extension), and sector-specific reviews may take longer if the BMWK escalates to a formal investigation.
• The Bundeskartellamt will not wait for FDI clearance before issuing its own decision, but closing remains prohibited until both clearances are obtained.
• Running both filings in parallel from signing is strongly recommended. Engaging the BMWK informally even before signing, particularly where the buyer is from a non-allied jurisdiction, can prevent unexpected delays.

Practical Case Study (Energy Sector)

Consider an East Asian energy company seeking to acquire a German offshore wind-farm operator. The target holds critical-infrastructure licences, triggering the sector-specific FDI screening threshold at 10 % of voting rights. Simultaneously, the combined turnovers exceed the GWB merger filing thresholds. The buyer must file with both the Bundeskartellamt and the BMWK. Early indications suggest that transactions in the energy sector are receiving heightened scrutiny, with the BMWK requesting detailed information about the buyer’s ownership structure, state affiliations and technology-transfer plans. Deal teams in this space should budget six to eight months between signing and closing to accommodate parallel reviews.

Remedies: Types, Negotiation Playbook and Real-World Examples

Where the Bundeskartellamt identifies competition concerns, the parties may offer commitments, commonly referred to as remedies, to secure clearance and avoid a prohibition. Understanding the Bundeskartellamt’s approach to remedies divestment Germany is essential for deal-planning purposes.

Drafting Divestment Clauses in the SPA

Best practice is to include a divestiture commitment clause in the SPA from the outset, even where clearance is expected without conditions. Key elements include:

• A commitment by the buyer to offer divestiture packages to the Bundeskartellamt if required, within agreed parameters (e.g., maximum scope of assets to be divested).
• A “crown jewel” provision identifying a fallback divestiture package if the primary offer is rejected.
• A regulatory longstop date after which either party may terminate if clearance has not been obtained.
• An allocation of risk as to which party bears the cost of divestiture (legal fees, adviser fees, value erosion).

Trustee and Hold-Separate Mechanics

Where remedies involve a post-closing divestiture, the Bundeskartellamt typically requires the appointment of a monitoring trustee and, in some cases, a divestiture trustee with a mandate to sell the divestment business within a fixed window if the parties fail to do so. During the divestiture period, hold-separate obligations ring-fence the business to preserve its competitive viability. Deal teams should plan for these mechanics in their integration playbooks, as they restrict operational decision-making over the divested perimeter.

Practical M&A Regulatory Checklist and Sample Timeline

The following client-ready checklist distils the key actions, owners and timing milestones for a German merger clearance process. The likely practical effect of following this sequence is a significantly reduced risk of gun-jumping, clock-stopping delays and regulatory longstop breaches.

SPA Drafting Red Flags

• Missing suspensive condition. Every SPA involving a notifiable German concentration must include a condition precedent making closing contingent on Bundeskartellamt clearance. Omitting this exposes the buyer to gun-jumping liability.
• Unrealistic longstop date. Setting the regulatory longstop at less than six months from signing creates pressure if the case enters Phase II or if parallel FDI review is required.
• Ambiguous remedies authority. The SPA should clearly state who has authority to negotiate and agree remedies with the Bundeskartellamt, and set outer limits on what may be offered without the seller’s consent.

Deal Governance and Escalation

Designate a single regulatory workstream lead within the deal team, with a reporting line to the steering committee. Establish weekly status calls with external counsel during the review period. Build escalation triggers for Phase II entry, remedy requests and BMWK escalation so that senior management is engaged before deadlines tighten. In Germany’s evolving regulatory environment, early alignment between legal, commercial and board-level stakeholders is critical.

Sector Considerations: Energy and Technology in Cross-border M&A Germany

Energy

Energy-sector transactions attract scrutiny from multiple regulators simultaneously. Beyond merger control and FDI screening, buyers must assess whether grid-access licences, generation permits or subsidy entitlements (e.g., under the Renewable Energy Act, EEG) are transferable or require separate regulatory consent. The Bundesnetzagentur (Federal Network Agency) may also have oversight where transmission or distribution assets are involved. The combined effect of merger control, FDI screening and sector-specific energy regulation can extend the signing-to-closing timeline to nine months or more in complex cases.

Technology (AI, Dual-Use)

Acquisitions in the technology space, particularly those involving artificial-intelligence capabilities, cybersecurity products, semiconductor IP or dual-use goods, face sector-specific FDI screening at the 10 % voting-rights threshold. Export-control compliance under the EU Dual-Use Regulation (Regulation (EU) 2021/821) adds a further layer of due diligence. Buyers should verify whether the target holds export licences that are personal to the licence holder and may not survive a change of control, and whether technology-transfer restrictions apply to post-acquisition integration plans. Germany’s fast-evolving regulatory landscape means that deal teams must review sector-specific rules at the time of each transaction rather than relying on prior precedents.

Conclusion: Navigating Merger Control Germany in 2026 and Beyond

Merger control Germany remains a mandatory, suspensory regime that demands early and thorough planning by every buyer targeting a German business. The core message for deal teams is straightforward: assess the filing obligation at the earliest stage of the transaction, engage the Bundeskartellamt in pre-notification discussions, file promptly after signing and run FDI screening (where applicable) in parallel. Allocate sufficient time in the SPA longstop, six months is a prudent minimum for any transaction that may enter Phase II or trigger FDI review.

Buyers who build merger control and FDI clearance into their deal governance framework from the outset will minimise timing risk, avoid gun-jumping exposure and preserve negotiating leverage on remedies. Those who treat regulatory clearance as an afterthought risk costly delays, abortive transactions and enforcement action.
