How to Structure Cross‑border M&A to Navigate Hungary's FDI Screening and Merger Control

Last updated 14 May 2026

Any cross‑border buyer, PE sponsor or lender structuring M&A in Hungary must now plan around two overlapping foreign‑direct‑investment regimes, and the FDI notification Hungary obligations that flow from them can reshape deal timelines, break‑fee economics and completion mechanics. Act L of 2025, which entered into force on 19 August 2025 and codified the Special FDI Regime on a permanent statutory footing, introduced expanded sector coverage, tightened notification thresholds and granted the Hungarian state new pre‑emption rights over strategic companies. Subsequent 2025–2026 amendments added narrow financing exemptions that ease, but do not eliminate, notification burdens for secured lenders.

This guide is a practitioner‑level playbook: it walks deal teams through trigger analysis, sequencing with merger control Hungary filings, transaction timelines, and the specific SPA clauses needed to allocate FDI risk on deals closing in 2026.

Executive Summary: What Deal Teams Must Know Now

Before diving into detail, here are the four facts that should shape every term sheet and SPA drafted for a Hungarian target in 2026:

• Two parallel regimes apply. The General FDI Regime (Act LVII of 2018) and the Special FDI Regime (Act L of 2025) operate concurrently. A single transaction can trigger notifications under both, each administered by different authorities with different timelines.
• Financing exemptions are narrow, not broad. Amendments introduced in late 2025 and early 2026 exempt certain bank‑financing and security arrangements from notification, but only where the lender does not acquire operational control or voting rights. Pledges over assets deemed indispensable to strategic companies Hungary remain notifiable regardless of value.
• Review timelines have lengthened. Under the Special Regime the statutory review window can now extend well beyond the earlier 45‑ or 75‑working‑day benchmarks. Deal teams should model a realistic worst‑case of up to 180 calendar days from filing to clearance when setting long‑stop dates.
• Three SPA actions are non‑negotiable. Every transaction touching a Hungarian strategic target should include (a) a regulatory‑condition precedent tied to FDI clearance, (b) an extended long‑stop date calibrated to the longest plausible review window, and (c) an escrow or hold‑back mechanism to bridge the gap between signing and completion.

Overview: Hungary’s Two FDI Regimes (General vs Special)

Hungary’s FDI screening architecture rests on two distinct statutes. Understanding which regime, or both, applies is the first step in any deal analysis.

General FDI Regime, Act LVII of 2018

The General Regime was Hungary’s original screening mechanism. It applies to acquisitions by non‑EU/non‑EEA investors in companies operating in designated sectors such as defence, dual‑use goods, financial services, certain utilities and electronic communications. The reviewing authority is the Minister responsible for the relevant sector, with the Ministry of National Economy coordinating. Notification is mandatory and must be filed before closing; completing without clearance renders the transaction void.

Special FDI Regime, Act L of 2025

Originally introduced as an emergency government decree during the COVID‑19 pandemic, the Special Regime was made permanent by Act L of 2025 (effective 19 August 2025). Its scope is significantly wider: it captures investments by all foreign, including EU/EEA, investors and covers a broader list of strategic companies Hungary, from energy and water utilities to critical raw‑material processors and pharmaceutical manufacturers. Thresholds are lower, and the regime introduces state pre‑emption rights absent from the General framework.

What Triggers FDI Notification in Hungary, Decision Flow

The fdi notification hungary obligation is triggered by a combination of investor nationality, target‑sector classification, transaction type and ownership thresholds. The following decision flow captures the analysis every deal team should run at the preliminary due‑diligence stage.

1. Is the investor “foreign”? Under the General Regime, only non‑EU/EEA investors qualify. Under the Special Regime, any investor whose ultimate beneficial owner is domiciled outside Hungary may qualify.
2. Does the target operate in a designated sector? Cross‑reference the target’s activities against both the General Regime sector list and the broader Special Regime categories.
3. Does the transaction cross an ownership or control threshold? See the table below.
4. Does the transaction involve asset transfers or operational rights? Pledging, transfer of use‑rights or operational licences for critical infrastructure can independently trigger notification.

Ownership Thresholds

Asset and Operational‑Rights Triggers

Act L of 2025 extends fdi screening hungary obligations beyond share acquisitions. Granting a security interest, pledge or right of use over assets deemed indispensable to the operation of a strategic company triggers notification regardless of the value of the assets involved. This is a critical point for lenders: a pledge over a solar farm’s grid‑connection licence, for instance, is notifiable even if the lender has no intention of exercising operational control.

Reporting Obligations by Transaction Type

Act L of 2025: Key Changes and the Financing Exemption Explained

The codification of the Special FDI Regime through Act L of 2025 was the most significant change to Hungary’s investment‑screening landscape in years. The Act, which entered into force on 19 August 2025, replaced emergency government decrees that had been renewed repeatedly since 2020 and placed the regime on a permanent legislative footing. For deal teams engaged in M&A Hungary transactions, the practical implications fall into three areas: widened scope, new pre‑emption rights and clarified, but narrow, financing exemptions.

The FDI Financing Exemption: Scope and Limits

Following sustained lobbying by the banking sector, amendments to Act L introduced in late 2025 and formalised in early 2026 carved out certain financing transactions from the notification obligation. The fdi financing exemption applies where a credit institution takes security over the assets of a strategic company solely for the purpose of securing repayment of a loan, provided the lender does not acquire voting rights, board‑nomination rights or any form of operational control over the target. The exemption is narrow by design: it does not cover mezzanine or convertible instruments that carry equity‑conversion features, nor does it cover situations where the lender has step‑in rights that would give it operational management of the strategic asset.

Deal teams drafting security packages should ensure that loan agreements expressly disclaim control rights and that intercreditor arrangements do not inadvertently grant a foreign lender the ability to direct operational decisions.

State Pre‑Emption and Sector‑Specific Rules

Act L of 2025 grants the Hungarian state a pre‑emption right over shares and certain assets of designated strategic companies. This is particularly relevant in the energy sector. Where a transaction involves the sale of a solar‑energy facility (naperőmű) or other critical energy infrastructure, the state may exercise its pre‑emption right, and the parties must allow a statutory waiting period for that right to be exercised or waived before completion can occur. Industry observers expect the government to use this power selectively, focusing on large‑scale energy assets and critical raw‑material sites, but the mechanism creates deal‑timing uncertainty that must be priced into every SPA.

Interaction with Hungarian Merger Control: Sequencing and Dual Filings

A cross‑border acquisition in Hungary can trigger both an FDI notification and a merger control filing with the Hungarian Competition Authority (Gazdasági Versenyhivatal, or GVH). The two processes are legally independent, administered by different bodies and operate on different timelines. Failing to manage both creates the risk of gun‑jumping penalties on the competition side and voidable‑transaction consequences on the FDI side.

Sequencing options. The two filings can be submitted simultaneously, there is no legal prohibition, and simultaneous filing is typically the most efficient approach for straightforward transactions. However, where a transaction is likely to face an extended FDI review (e.g., because it involves a sensitive sector), some deal teams opt to file the merger control notification first to secure GVH clearance while the FDI review proceeds. The SPA should accommodate both scenarios by making completion conditional on clearance from both authorities and by setting a long‑stop date that reflects the longer of the two review windows.

Practical 0–180 Day Deal Timetable for FDI Notification Hungary Transactions

The following timetable reflects realistic transaction timelines for a deal that triggers both FDI and merger control obligations in 2026. It is calibrated to the extended review windows under Act L of 2025.

These transaction timelines FDI are indicative. Every deal should be calibrated to its specific sector, investor profile and structural complexity. A downloadable one‑page FDI deal timeline and checklist for buyers is available as a companion resource.

SPA Clauses and Negotiation Levers to Allocate FDI Risk

The centrepiece of any well‑structured M&A Hungary transaction involving a strategic target is the SPA itself. Below are sample clauses, concise, editable and ready for adaptation, covering the six areas where spa drafting hungary must address FDI risk.

Notification and Cooperation Clause

Sample clause 1, Buyer’s filing obligation:

“The Buyer shall prepare and file all FDI notifications required under Act LVII of 2018 and/or Act L of 2025 within five (5) Business Days of signing, and shall promptly provide the Seller with copies of all submissions and correspondence with the reviewing authority.”

Sample clause 2, Seller’s cooperation obligation:

“The Seller shall provide, and shall procure that the Target Company provides, all information and documents reasonably requested by the Buyer for the purpose of preparing and supporting the FDI notification(s), within five (5) Business Days of each such request.”

Long‑Stop Date / Termination / Frustration

Sample clause 3, Extended long‑stop:

“The Long‑Stop Date shall be the date falling 210 calendar days after the date of this Agreement, provided that either Party may extend the Long‑Stop Date by up to 60 additional calendar days by written notice if any FDI review remains pending.”

Sample clause 4, Termination right:

“If FDI clearance has not been obtained by the Long‑Stop Date (as extended), either Party may terminate this Agreement by written notice without liability, save for the provisions of Clause [X] (Break Fee) which shall survive termination.”

Reverse Break Fee / Break Fee Mechanics

Sample clause 5, Reverse break fee:

“If this Agreement is terminated because FDI clearance is refused or made subject to conditions unacceptable to the Buyer acting reasonably, the Buyer shall pay to the Seller a reverse break fee of [●]% of the Purchase Price within ten (10) Business Days of termination.”

Completion on Condition Precedent vs Hold‑Back

Sample clause 6, Conditional completion:

“Completion is conditional upon receipt of unconditional FDI clearance and GVH merger control clearance. The Buyer shall not be obliged to complete, and the Seller shall not be obliged to transfer the Shares, until both conditions are satisfied or waived.”

Sample clause 7, Escrow hold‑back:

“On Completion, 10 % of the Purchase Price shall be deposited into the Escrow Account and released to the Seller upon the earlier of (a) unconditional FDI clearance or (b) the expiry of 180 days from Completion without the reviewing authority having issued a prohibition decision.”

Financing and Security Treatment

Sample clause 8, Bank security carve‑out:

“The Parties acknowledge that the grant of security over Target assets to the Buyer’s financing banks does not confer voting rights, board‑nomination rights or operational control on the secured parties, and is intended to fall within the financing exemption under Act L of 2025 as amended. The Buyer shall procure that all facility agreements contain express disclaimers of control rights.”

These sample clauses reflect common market practice but should always be tailored to the specific deal structure.

Understanding deadlock provisions in shareholders agreements is also essential where joint‑venture structures are used as an alternative to full acquisitions.

Sector Playbook: Energy, Infrastructure, IT and Critical Suppliers

Not all FDI notifications carry the same risk profile. The following sectors attract the highest level of scrutiny, and the greatest probability of extended review or state pre‑emption, under the Special FDI Regime:

• Energy (including solar / naperőmű). The state’s pre‑emption right is most actively exercised here. Solar‑farm transactions have been flagged as a priority by the reviewing authority. Allow a statutory waiting period for the pre‑emption right to be exercised or waived before completion.
• Critical infrastructure (water, transport, telecoms networks). Pledges and operational‑rights transfers trigger notification even at minimal value. In‑depth reviews are common; factor in an extended timeline.
• IT security and electronic communications. Acquisitions of companies handling classified data or operating national‑security‑relevant IT systems face parallel scrutiny from national‑security bodies.
• Critical raw materials and pharmaceuticals. Post‑pandemic supply‑chain concerns have expanded the list of strategic companies in these subsectors. Early pre‑notification consultation is strongly recommended.

Risk Allocation: Insurance, Escrows, W&I and Enforcement Considerations

FDI risk should be priced explicitly in the transaction, not left to general indemnity provisions.

• W&I insurance. Warranty‑and‑indemnity policies typically exclude losses arising from regulatory prohibition. Deal teams should negotiate express coverage extensions or, more commonly, accept the exclusion and address the risk through structural mechanisms (break fees, escrows).
• Escrow accounts. A purchase‑price escrow of 5–15 % is market standard for transactions with material FDI risk. The escrow should have clear release triggers linked to FDI clearance timelines.
• Enforcement if the state blocks. If the reviewing authority prohibits the transaction or imposes unacceptable conditions, the SPA should specify each party’s remedies, including break fees, cost‑sharing and the return or release of escrowed funds.
• State pre‑emption compensation. Where the state exercises its pre‑emption right, the seller receives the price agreed in the SPA (or, in some cases, a price determined by independent valuation). SPA drafting should address which price mechanism applies and whether the buyer is entitled to a break fee in this scenario.
