FDI Screening in Hungary 2026: Notification Thresholds, Strategic Sectors and Approval Timelines

FDI screening in Hungary has entered a pivotal phase in 2026, shaped by the January easing of notification obligations for certain “strategic companies” and the gradual sunsetting of temporary measures introduced during 2025. For in-house counsel, private equity teams and external M&A advisers structuring cross-border acquisitions into Hungary, the practical challenge is acute: two parallel notification regimes operate simultaneously, each with distinct triggers, filing routes and suspensory consequences. This guide delivers the operational detail that deal teams need, exact thresholds, ministerial filing routes, approval timelines, interaction with GVH merger control and a step-by-step structuring checklist, grounded in Act LVII of 2018 and the latest government decrees published in the Magyar Közlöny.

Executive Summary, What Changed in 2025–2026 and Immediate Implications for Deal Teams

Hungary’s foreign direct investment control framework, anchored by Act LVII of 2018 on the Control of Foreign Investments Detrimental to the Security Interests of Hungary, has undergone successive refinements since its original entry into force on 1 January 2019. Throughout 2025, targeted government decrees introduced carve-outs for certain bank financing and security arrangements, narrowing the scope of transactions that require ministerial approval. These amendments were published in the Magyar Közlöny and codified through implementing decrees accessible via the Nemzeti Jogszabálytár (NJT).

The most consequential development for 2026 is the January easing for “strategic companies.” Under revised government decrees, certain entities previously classified as strategic have been reclassified, reducing, though by no means eliminating, notification obligations for transactions involving those companies. Industry observers expect this reclassification to streamline deal timelines in sectors such as certain manufacturing and services verticals, while core strategic sectors (defence, energy, critical infrastructure) remain fully within scope. At the same time, market commentary flags the possibility that some 2025 temporary measures may sunset at year-end, meaning deal teams should monitor the Official Gazette for definitive acts throughout the second half of 2026.

If you only read three things:

• Notification remains mandatory and suspensory for covered transactions under both the General FDI Regime (Act LVII/2018) and the sectoral/national-security regime, closing before ministerial clearance risks invalidity.
• The January 2026 easing narrows, but does not abolish, notification scope. Every acquisition must still be screened against current sector lists and threshold triggers before signing.
• Dual-filing risk is real. Many transactions that trigger FDI notification also meet GVH merger control thresholds. Sequencing both filings correctly is critical to avoid gun-jumping exposure.

FDI Screening in Hungary: Notification Thresholds and Who Must File

Two Parallel Regimes

Hungary operates two distinct but overlapping Hungary FDI control regimes. Understanding which regime applies, and whether both do, is the first step in any acquisition analysis.

The General FDI Regime, established by Act LVII of 2018, applies to investments by “foreign investors” (broadly, investors from outside the European Economic Area, or EEA entities ultimately controlled by non-EEA persons) in Hungarian companies operating in designated strategic sectors. The regime covers acquisitions of qualifying ownership stakes, voting rights or decisive influence. The notification obligation is triggered when a foreign investor acquires, directly or indirectly, ownership or voting rights reaching or exceeding certain thresholds in a Hungarian target company that is active in a designated sector listed in the Act and its implementing decrees.

The sectoral/national-security regime operates alongside the General FDI Regime and captures transactions in specific high-sensitivity sectors (defence, dual-use technology, certain critical infrastructure) regardless of investor nationality in some circumstances. This regime may apply even to intra-EEA investments where national-security interests are engaged.

Defining the “Foreign Investor”

Under Act LVII of 2018, a foreign investor is generally a natural or legal person domiciled, or having its registered seat, outside the EEA. Crucially, an EEA-incorporated entity may still qualify as a foreign investor if it is ultimately controlled, directly or indirectly, by a non-EEA person. Deal teams should trace beneficial ownership chains early in due diligence to determine notification status.

Trigger Events and Filing Obligations

The filing obligation rests on the foreign investor, not the Hungarian target. However, in practice, deal documentation frequently allocates cooperation duties to the target (providing sector-classification information, operational data and financial statements) to enable timely filing.

Strategic Sectors, Exemptions and the January 2026 Easing

The strategic sectors designated under Hungary’s FDI regime determine whether a transaction falls within the notification net. Act LVII of 2018, together with its implementing government decrees, lists specific NACE activity codes and sector descriptions. The January 2026 amendments narrowed the classification of certain “strategic companies,” but the core sector categories remain broadly intact.

Sector-by-Sector Filing Risk

The 2025–2026 Exemptions

Throughout 2025, government decrees published in the Magyar Közlöny introduced targeted exemptions. The most significant for deal structuring are carve-outs for certain bank financing and security arrangements, transactions where a lender acquires security over shares in a strategic-sector target as part of a bona fide financing arrangement, rather than as a route to operational control. These exemptions remain narrow and condition-specific; deal teams should not assume blanket applicability without confirming that the specific structure satisfies all requirements of the relevant decree.

The January 2026 easing for strategic companies represents a reclassification rather than a wholesale exemption. Certain entities previously captured by the strategic-company designation have been moved outside the mandatory notification perimeter. The likely practical effect will be that acquisitions in mid-tier manufacturing and some services verticals face reduced FDI filing obligations, but buyers must verify the current classification of the specific target entity against the latest government decree (published via the NJT). The easing does not affect the core strategic sectors listed above.

Filing Process, Ministerial Route and FDI Approval Timeline in Hungary

The filing process for foreign direct investment Hungary 2026 transactions follows a structured ministerial route. Understanding each stage, and the realistic time benchmarks beyond statutory minimums, is essential for building credible deal timelines.

Step-by-Step Filing Process

• Pre-notification consultation (voluntary). Foreign investors may engage informally with the competent minister’s office before formal filing. Early indications suggest that pre-notification consultations can materially reduce formal review times by identifying information gaps and sector-classification questions in advance.
• Formal notification to the competent minister. Under the General FDI Regime, the competent authority is the minister leading the Prime Minister’s Cabinet Office (Miniszterelnöki Kabinetiroda). Notifications must be submitted in Hungarian; supporting documents (SPAs, corporate charts, financial statements) should be provided with certified Hungarian translations.
• Document requirements. The filing typically includes the identity and ownership structure of the foreign investor, details of the target and its sector classification, the transaction documents (or drafts), financial data, and a description of the post-acquisition operational plans.
• Fees. No formal government filing fee applies to FDI notifications under the General FDI Regime, although professional advisory and translation costs should be budgeted.
• Acknowledgement and review. The minister’s office acknowledges receipt and commences the statutory review period.

Timeline: Statutory Review and Practical Benchmarks

Suspensory effect: For covered transactions, notification has a suspensory effect. The foreign investor may not complete the acquisition, and the target may not register the resulting ownership change, until ministerial clearance is obtained. Closing before clearance constitutes gun-jumping and risks the transaction being declared invalid.

Interaction With GVH Merger Control and Timing Coordination

Many transactions that trigger FDI notification also meet the merger control thresholds Hungary 2026 administered by the Gazdasági Versenyhivatal (GVH). The GVH applies separate turnover-based tests under the Hungarian Competition Act, requiring notification where the combined and individual net turnover of the participating undertakings exceeds designated HUF thresholds. The GVH provides detailed guidance on its “I will buy an undertaking” filing page.

Dual-Filing Scenarios

• Share acquisition exceeding both FDI and GVH thresholds. A non-EEA buyer acquiring 100% of a Hungarian energy company will likely trigger both ministerial FDI notification (strategic sector) and GVH merger notification (if turnover thresholds are met). Both filings carry a suspensory effect; coordinate timelines to avoid one clearance expiring before the other is obtained.
• Joint venture formation. A JV between an EEA company and a non-EEA partner in a strategic sector may require FDI notification (for the non-EEA partner’s participation) and GVH merger notification (if the JV constitutes a full-function concentration meeting turnover thresholds). Assess both regimes at the structuring stage.
• Asset acquisition below GVH thresholds. A foreign investor acquiring specific assets (e.g., a telecom licence and related infrastructure) in a strategic sector may trigger FDI notification without reaching GVH turnover thresholds. In this case, only ministerial clearance is required, but the GVH retains the ability to initiate ex post reviews within its statutory window.

The sequencing recommendation for most dual-filing transactions is to file both notifications in parallel, aiming for coordinated clearance dates. Pre-notification consultations with both the minister’s office and the GVH can help identify timing risks before formal filings are submitted. The GVH merger notification process follows its own statutory timetable, and practitioners should consult the GVH’s published guidance for current procedural requirements.

Practical Deal-Structuring Checklist for Buyers

Transaction teams evaluating foreign direct investment Hungary 2026 opportunities should integrate FDI screening into every phase of the deal process. The following checklist provides a structured framework.

• Due diligence red flags. Identify the target’s NACE activity codes and cross-reference against the current sector list in the implementing decrees. Trace the buyer’s ultimate beneficial ownership to determine “foreign investor” status. Flag any prior FDI notifications or conditions attached to the target.
• Structuring to reduce notification risk (where lawful). Consider whether restructuring the buyer vehicle within the EEA, without artificial arrangements designed solely to circumvent notification, could affect foreign-investor classification. Note that look-through provisions apply; substance is required.
• Drafting conditions precedent (CPs). Include a specific FDI-clearance CP in the SPA, distinct from any GVH merger-control CP. Sample language: “Completion is conditional upon the Buyer having received written confirmation from the competent minister that the Transaction is not prohibited or is approved (with or without conditions) under Act LVII of 2018.”
• Suspensory approval clause. Where both FDI and GVH clearances are required, draft a combined regulatory CP that prevents closing until both approvals are obtained: “Neither Party shall be obliged to complete the Transaction until both (a) ministerial clearance under Act LVII of 2018 and (b) GVH merger clearance under the Competition Act have been obtained or are deemed obtained.”
• Lender and security carve-outs. For leveraged acquisitions, confirm whether the 2025 financing exemptions apply to the specific security package. If shares in the strategic-sector target are pledged to lenders, the pledge itself may require notification unless an exemption applies. Draft the security documents to address this contingency.
• Escrow and long-stop dates. Set realistic long-stop dates reflecting the combined FDI and GVH review timelines. Consider escrow arrangements for purchase price payments to protect both parties during the clearance period.
• Contingency planning. Include termination rights (break fees, reverse break fees) triggered by regulatory prohibition or failure to obtain clearance by the long-stop date. Address allocation of regulatory risk in the risk-sharing provisions.

Compliance Risk and Penalties, Ex Post Investigations, Invalidity and Remedies

Failure to notify a covered transaction carries significant legal consequences. Under Act LVII of 2018, a transaction completed without the required ministerial approval may be declared invalid. The competent minister retains the authority to open ex post investigations, and market guidance references a lookback period of up to five years from closing. While automatic criminal penalties are not the primary enforcement tool, administrative measures, including orders to unwind or divest, represent a material risk. The emphasis of enforcement is on remediation: the minister may impose conditions, require structural commitments or, in the most serious cases, prohibit the transaction retrospectively. Deal teams should treat notification compliance as non-negotiable for any transaction within the screening perimeter.

Conclusion, Recommended Next Steps for Deal Teams

FDI screening in Hungary remains a mandatory, suspensory process for foreign investors targeting strategic-sector companies, despite the January 2026 easing. Deal teams should adopt a three-step approach: first, screen every target against the current sector lists and implementing decrees at the earliest stage of the transaction process; second, coordinate ministerial FDI filings and GVH merger notifications in parallel, using pre-notification consultations to identify and resolve issues before formal submission; third, draft SPAs with dedicated FDI-clearance CPs, realistic long-stop dates and escrow mechanisms that reflect the combined regulatory timeline. Proactive compliance planning is the most effective way to protect deal certainty and avoid the severe consequences of non-notification.
