How to File a Mandatory Takeover Bid in Hungary (2026): Thresholds, Pricing Rules, Exemptions and Timeline

A mandatory takeover bid Hungary requirement is triggered the moment an acquirer crosses a defined ownership threshold in a company whose shares are admitted to trading on a regulated market operated by the Budapest Stock Exchange. For in-house counsel, private equity sponsors, strategic buyers and brokers active in the Central and Eastern European market in 2026, understanding exactly when the obligation arises, how the offer price is calculated, which exemptions apply and how long the process takes is the difference between a clean deal and a regulatory intervention.

This guide sets out the practical mechanics of the Hungarian public tender offer regime, grounded in the Act on the Capital Market (Act CXX of 2001), the supervisory practice of the Magyar Nemzeti Bank (MNB) and the listing rules of the Budapest Stock Exchange. It is written for acquirers and their advisers who need a regulation-first walkthrough rather than a marketing overview.

Quick summary and key takeaways

Before diving into the detail, the essentials of a mandatory takeover bid Hungary process can be distilled into a handful of practical points. This section serves as a TL;DR for counsel and executives who need the headline position first.

• Trigger. Acquiring or gaining control over voting rights in a Hungarian listed company above the statutory threshold set out in the Act on the Capital Market obliges the acquirer to launch a public tender offer for the remaining shares.
• Acting in concert. Holdings of parties acting in concert are aggregated for threshold purposes, so purchases cannot be split among coordinated parties to avoid the obligation.
• Pricing. The offer price must not fall below the statutory floor, which is anchored to the highest and average prices the bidder (and concert parties) paid over defined look-back periods and to recent market prices.
• Exemptions. Statutory carve-outs and MNB practice recognise certain reorganisations, intra-group transfers and defined situations where no mandatory bid is required.
• Timeline. From the triggering event through MNB approval, the acceptance window and settlement, a typical mandatory bid runs across an eight-to-twelve-week horizon, subject to regulatory review and any parallel competition or FDI filings.

What triggers a mandatory takeover bid in Hungary?

The obligation to make a mandatory takeover bid Hungary arises under the takeover provisions of the Act on the Capital Market (Act CXX of 2001), which transpose the principles of the EU Takeover Bids Directive (Directive 2004/25/EC) into Hungarian law. The core rule is protective: once a person, alone or together with parties acting in concert, acquires a proportion of voting rights that confers control over a company whose shares are listed on a regulated market, that person must offer to buy out the remaining shareholders on equal terms. The rationale mirrors the EU framework, minority shareholders should have the opportunity to exit at a fair price when control of “their” company changes hands.

The statutory trigger

The trigger is the acquisition of a controlling stake in a listed Hungarian company, measured by reference to voting rights. The precise threshold and the mechanics of how voting rights are counted are set out in the consolidated text of the Act on the Capital Market, available through the official Hungarian legislation portal. Because the regime is anchored to voting rights rather than to the bare number of shares held, the analysis must account for share classes carrying different voting entitlements, treasury shares that do not vote, and any voting arrangements that shift effective control. The trigger is objective: it does not depend on the acquirer’s intention to take control, only on the level of voting rights crossed.

Practical examples of triggering events

A mandatory takeover bid Hungary obligation can arise in a variety of ways beyond a simple on-market or off-market share purchase:

• Direct share purchases. Buying voting shares from one or more sellers so that the acquirer’s aggregate holding crosses the threshold.
• Conversions and subscriptions. Converting instruments into voting shares, or subscribing for new shares in a capital increase, that pushes voting rights over the line.
• Changes in control relationships. Acquiring control over an entity that itself holds shares in the listed target, so that voting rights are attributed up the chain.
• Derivative and voting arrangements. Entering into agreements that confer effective control over the exercise of voting rights, even where legal title has not yet passed, may bring the acquirer within scope.

Each of these routes should be tested against the statutory definition of control before completion. Where the analysis is finely balanced, seeking the MNB’s view in advance is prudent, because the consequences of an inadvertent trigger, including a late or non-compliant bid, are significant.

Thresholds and acting in concert, calculation and tests

The threshold analysis is the single most consequential step in any mandatory takeover bid Hungary assessment, because it determines whether the obligation exists at all. The Act on the Capital Market fixes the percentage of voting rights that constitutes control for takeover purposes, and it requires that the holdings of all parties acting in concert be added together when measuring that percentage. Getting the aggregation wrong, either by overlooking a concert relationship or by mis-counting non-voting instruments, is the most common cause of enforcement exposure.

Definition of control and acting in concert

Control, for takeover purposes, is defined by reference to the proportion of voting rights held. “Acting in concert” captures persons who cooperate on the basis of an agreement, whether express or tacit, aimed at acquiring control of the target or at frustrating the successful outcome of a bid. The concept is deliberately broad. It reaches formal shareholder agreements, but also less visible arrangements where two or more parties coordinate their conduct with a common purpose in relation to the target. Board and control relationships are relevant: parent and subsidiary entities, and companies under common control, are typically treated as a single interest for threshold purposes.

The Kúria, Hungary’s supreme court, is the ultimate arbiter of how these tests apply in disputed cases, and its judgments on the interpretation of concert relationships should be consulted where a structure is novel.

Party aggregation examples

Consider three illustrative scenarios that show how aggregation works in practice:

• Concert parties. Two private equity funds enter a co-investment agreement to acquire and jointly control a listed target. Even if neither fund individually crosses the threshold, their combined voting rights are aggregated, and if the combined figure crosses the line the obligation is triggered.
• Nominee and custody accounts. Shares held through nominee or custodian accounts on behalf of the same beneficial owner are attributed to that owner. Splitting a stake across multiple custody arrangements does not defeat aggregation where the beneficial interest is common.
• Institutional investor with a controlled entity. An institutional investor that holds shares directly and also controls a subsidiary holding further shares must count both blocks together, because the voting rights of the controlled entity are attributed to the controller.

In each case, the practical test is whether voting rights are, in substance, under common direction. The regime is designed to look through form to substance, which is why anti-avoidance considerations sit at the heart of the acting in concert Hungary rules.

Enforcement and sanctions

The MNB supervises compliance with the takeover regime and has a range of powers where an acquirer fails to launch a required bid or launches one on non-compliant terms. Supervisory measures can include suspension of the exercise of voting rights attached to the improperly acquired shares, orders to remedy the breach, and financial penalties. Because these consequences can strand an acquisition, leaving the buyer holding shares it cannot vote, the incentive to get the threshold analysis right before completion is strong.

When to seek pre-bid MNB engagement: where the structure involves concert parties, layered holding companies, derivative positions, multiple share classes, or any voting arrangement short of full legal title, the prudent course is to obtain MNB clearance or informal guidance before crossing the threshold, and to document the analysis contemporaneously.

Pricing rules, how to calculate the mandatory offer price for a mandatory takeover bid Hungary

Once the obligation is established, the offer price becomes the central commercial question. The takeover bid pricing Hungary rules are designed to ensure that minority shareholders receive no less than the price the acquirer was itself willing to pay in the run-up to gaining control, and no less than a fair reflection of recent market value. The Act on the Capital Market sets a statutory floor built from these reference points, and the MNB reviews the proposed price as part of its approval of the offer document.

The standard statutory formula

The minimum price for a mandatory takeover bid Hungary offer is determined by taking the higher of defined benchmarks. In broad terms, the floor is anchored to the highest price the bidder and any parties acting in concert paid for the target’s shares during a statutory look-back period before the trigger, and to an averaged market price over a defined reference window. The proposed price must be at least equal to that floor. The step-by-step approach for advisers is:

1. Identify every acquisition of target shares by the bidder and concert parties within the statutory look-back period.
2. Determine the highest per-share price paid in those acquisitions, converting any foreign-currency consideration into forints at the applicable rate.
3. Calculate the averaged market price over the statutory reference window using exchange data.
4. Set the offer price at no less than the higher of these figures, applying the relevant benchmark for the share class in question.

Because the exact look-back periods and averaging method are prescribed by the consolidated statute and applied through MNB practice, the calculation must be reproduced precisely from the primary source for each transaction. A price set below the floor will not be approved.

Special cases: non-cash consideration, partial tendering and share classes

Several situations require additional care:

• Non-cash consideration. Where the bidder acquired shares for securities or other non-cash consideration, that consideration must be valued to test it against the price floor, and the offer may need to include a cash alternative so that all shareholders can realise fair value.
• Different share classes. A listed company with multiple classes of shares carrying different rights may require the price to be assessed class by class, since the reference transactions and market prices differ between classes.
• Options, warrants and derivatives. Instruments giving a right to acquire shares, or economic exposure to them, may feed into the pricing analysis where they were part of the bidder’s route to control.

Worked calculations

To illustrate, suppose an acquirer bought target shares at HUF 1,200 and later at HUF 1,350 within the look-back period, while the averaged market price over the reference window was HUF 1,280. The floor is the higher of the highest price paid (HUF 1,350) and the averaged market price (HUF 1,280), so the mandatory offer must be at least HUF 1,350 per share. In a second example, if the highest price paid were HUF 1,100 but the averaged market price were HUF 1,290, the floor would be HUF 1,290, because the market benchmark is higher. In both cases, the bidder is free to offer more, but never less than the floor.

These figures are purely illustrative and do not reflect actual market prices.

A word of caution on disclosure: where the offer price differs from, or is set above, recent transaction prices, the offer document should explain the basis clearly, and any acquisitions above the offer price made during the bid may require the offer price to be increased to match, in line with equal-treatment principles.

Mandatory bid exemptions, safe harbours and carve-outs

Not every crossing of the threshold produces an obligation to launch a full offer. The regime recognises a set of mandatory bid exemptions Hungary that reflect situations where the policy rationale, protecting minorities against a change of control they did not choose, is absent or where the acquisition is technical in nature.

Common exemptions

The statutory framework and MNB practice recognise categories such as:

• Intra-group transfers. Movements of shares between entities under common control that do not change ultimate control of the target.
• Certain reorganisations. Corporate reorganisations, mergers and restructurings where control does not, in substance, change hands.
• Holdings below the threshold. Situations where, once non-voting or attributable holdings are correctly counted, the acquirer in fact remains below the control threshold.
• Compulsory or involuntary acquisitions. Acquisitions arising by operation of law or through defined non-voluntary routes.

Each exemption depends on the specific facts and on the precise statutory language, so the availability of a carve-out must be tested against the consolidated Act and current MNB practice rather than assumed.

How to apply for an exemption or notify the MNB

Where an exemption is relied upon, the acquirer should assemble contemporaneous documentation evidencing the basis for it, the group structure chart for an intra-group transfer, the reorganisation resolutions for a restructuring, or the shareholding analysis showing the holding remains below the threshold. Depending on the exemption, notification to or confirmation from the MNB may be appropriate, and timing matters: the analysis should be settled and documented before completion, not reconstructed afterwards. Treating exemptions as a matter to be confirmed with the regulator, rather than self-assessed and forgotten, materially reduces enforcement risk.

Process, documents and timeline, step-by-step

With the trigger, pricing and any exemption analysis settled, the execution phase of a mandatory takeover bid Hungary follows an ordered sequence from the triggering event through to settlement. The takeover bid timeline Hungary is driven by immediate disclosure duties, MNB review of the offer document, the acceptance window and settlement deadlines.

Required documents, the offer document checklist

The centrepiece filing is the offer document (public tender offer document), which functions much like a prospectus for the bid and must give shareholders the information they need to make an informed decision. A working checklist includes:

• Identity of the bidder and any parties acting in concert, and the resulting control position.
• The offer price and a clear explanation of how it satisfies the statutory floor.
• The form of consideration and any cash alternative.
• The bidder’s intentions regarding the target’s business, employees and listing.
• Financing confirmation demonstrating the bidder can meet the consideration.
• The acceptance mechanics, the acceptance period and settlement arrangements.
• Conditions to the offer, where permitted, and any regulatory approvals outstanding.

MNB timelines and review

The offer document must be submitted to the MNB for approval before publication. The MNB reviews the document for completeness and compliance, in particular the pricing analysis and the disclosure of the bidder’s control position and intentions. Statutory response periods apply, and where the MNB requests additional information the clock is affected accordingly. Because the review turns in practice on the complexity of the structure and the quality of the initial submission, bidders should build contingency into their timetable and treat the published statutory periods as a minimum rather than a guaranteed outcome. Early, complete filings shorten the overall path.

Interaction with Budapest Stock Exchange listing rules

Because the target is listed, the Budapest Stock Exchange rules run in parallel, alongside the EU Market Abuse Regulation (Regulation (EU) No 596/2014), which governs the disclosure of inside information. Disclosure of price-sensitive information, including the triggering acquisition and the intention to bid, must be made promptly. The applicable rules govern suspension of trading in defined circumstances and the eventual delisting process where a bidder acquires sufficient control to take the company private. Coordinating the exchange disclosure and listing steps with the MNB approval timetable is essential to avoid gaps or inconsistencies in the market’s information.

Sample eight-to-twelve-week timeline

• Day 0. Triggering acquisition completes; immediate disclosure of the crossing and the intention to launch a mandatory bid.
• Days 1–15. Prepare the offer document, finalise pricing analysis, secure financing confirmation and board notices.
• Days 15–20. Submit the offer document to the MNB for approval.
• Days 20–45. MNB review, including any requests for further information; parallel competition and FDI filings progress.
• Day ~45. MNB approval and publication of the offer document.
• Days 45–75. Acceptance window runs; shareholders tender their shares.
• Days 75–85. Close of acceptances, calculation of results, payment and settlement.

These day counts are indicative only; the actual duration depends on MNB review time, the statutory minimum and maximum acceptance periods prescribed by the Act on the Capital Market, the complexity of the structure and any parallel regulatory approvals.

Approvals, competition and FDI screening considerations

A mandatory takeover bid rarely proceeds in isolation from other regulatory clearances, and these can be the binding constraint on the timetable rather than the takeover process itself.

When to run parallel filings

Where the acquisition of control meets the relevant turnover thresholds, a merger control filing may be required with the Hungarian Competition Authority (Gazdasági Versenyhivatal, GVH), or with the European Commission where the EU dimension thresholds are met, and completion may be prohibited before clearance. Separately, foreign direct investment (FDI) screening can apply where the target operates in strategic or critical sectors, under Hungary’s FDI screening regimes administered by the responsible ministry, and an FDI approval may be a condition to closing. Both regimes should be assessed at the outset, because either can delay or block the deal.

Practical sequencing advice

The best practice is to run the merger control and FDI assessments in parallel with the offer document preparation, so that regulatory approvals are not discovered late. Where an approval is a condition to the offer, the offer document must disclose it clearly, and the acceptance and settlement timetable must accommodate the expected clearance timeline. Sequencing filings to start early, rather than waiting for MNB approval of the offer document, is usually the fastest route to close.

Post-offer mechanics: acceptances, squeeze-out, sell-out and delisting

The steps after the acceptance window closes determine whether the bidder achieves full ownership and can take the company private.

Squeeze-out procedure and timeline

Where the bidder reaches the statutory squeeze-out threshold following the offer, it may compulsorily acquire the remaining shares. The squeeze-out is time-bound following the close of the offer, and the price for squeezed-out shares is governed by rules designed to ensure minorities receive fair value, typically anchored to the offer price. The consolidated statute sets out the threshold and the procedural steps, and the exchange and MNB rules govern the associated disclosure and delisting consequences.

Minority protections and appraisal rights

The regime balances the squeeze-out right with sell-out protections, allowing minority shareholders who did not accept the offer to require the majority holder to buy their shares on equivalent terms in defined circumstances. Where minorities dispute the value they receive, avenues to challenge the price exist, reinforcing the fair-value principle that underpins the whole framework. Once the bidder holds a sufficient proportion of the share capital, delisting from the Budapest Stock Exchange follows under the exchange’s listing rules.

Comparison table, mandatory versus voluntary takeover offers

Acquirers frequently weigh a mandatory bid against a voluntary offer. The two routes differ in what triggers them, how the price is set and how much flexibility the bidder retains over the terms.

Practical checklist for acquirers and timeline template

A disciplined checklist keeps a mandatory takeover bid Hungary process on track from first analysis to settlement.

• Pre-deal. Map the target’s share and voting structure; identify all concert parties; test whether the acquisition crosses the control threshold; assess exemptions; scope merger control and FDI filings.
• Pre-launch. Finalise the pricing analysis against the statutory floor; confirm financing; draft the offer document; prepare exchange disclosures and board notices.
• Launch. Submit the offer document to the MNB; respond promptly to information requests; publish on approval; open the acceptance window; run parallel regulatory filings.
• Post-close. Calculate acceptances; settle and pay; assess squeeze-out; handle sell-out requests; complete delisting where full control is achieved.

Common pitfalls and risk mitigation

The recurring failures in Hungarian takeover practice are avoidable with the right controls in place.

• Mis-aggregating holdings. Overlooking a concert party or attributable holding, mitigate with a documented voting-rights map validated before completion.
• Late disclosure. Missing the immediate disclosure duty, build disclosure triggers into the deal timetable.
• Wrong price calculation. Using an incorrect look-back period, reproduce the statutory formula from the primary source and test with worked examples.
• Failing to notify the MNB. Treating the process as private, engage the regulator early where the structure is complex.
• Ignoring exchange rules. Overlooking suspension and delisting steps, coordinate the exchange and MNB timetables.
• Misreading exemptions. Assuming a carve-out applies, document the basis and confirm with the MNB.
• Payment and settlement failures. Underestimating settlement logistics, confirm financing and settlement arrangements up front.
• Ignoring FDI screening. Missing a sectoral approval, assess FDI and merger control at the outset and file early.

Conclusion

A mandatory takeover bid Hungary process rewards precision at every stage: an accurate threshold and acting-in-concert analysis, a pricing calculation reproduced exactly from the statutory floor, a documented assessment of any exemption, a complete offer document filed early with the MNB, and coordinated Budapest Stock Exchange disclosures alongside any competition and FDI clearances. For acquirers of Hungarian listed companies in 2026, treating each of these as a discrete, evidenced workstream, rather than assumptions to be reconstructed later, is what converts a control acquisition into a clean, closed transaction. Given the objective nature of the trigger and the real supervisory consequences of getting it wrong, local counsel should be engaged before the threshold is crossed, not after.
