Czech M&A Law Changes 2026, What Buyers and Sellers Must Know for Deals and Clearance

Last updated: 28 April 2026

The Czech Republic’s deal landscape is shifting materially in 2026, and any buyer or seller active in the jurisdiction needs to understand the implications before signing a term sheet. The Czech M&A law changes 2026 span three critical fronts: a significant overhaul of competition enforcement, including a new call‑in power for the Office for the Protection of Competition (ÚOHS), revised merger notification thresholds, and personal liability for managers, alongside amendments to takeover‑law mechanics and a major criminal‑law reform effective 1 July 2026 that introduces corporate criminal diversion.

Taken together, these reforms reshape how deals are structured, cleared and closed, creating fresh risk for the unprepared and a competitive edge for deal teams that adapt their diligence, drafting and clearance strategies early.

Executive Summary, What Changed in 2026 (Quick Read)

Three legislative and regulatory streams converge to reshape Czech M&A practice in 2026. First, a comprehensive amendment to the Act on the Protection of Competition introduces a call‑in model, raises certain turnover thresholds, equips ÚOHS with market intervention instruments, and, for the first time, exposes individual managers to personal fines for competition infringements. Second, the Czech takeover framework receives targeted updates affecting mandatory bid triggers, disclosure obligations and squeeze‑out procedures. Third, a major amendment to the Criminal Code, effective 1 July 2026, creates a corporate criminal diversion mechanism that directly impacts how compliance failures are assessed at the entity level.

On the deal‑mechanics front, practitioner commentary has also sharpened around pre‑closing dividends and working capital adjustments, areas where the gap between Czech market practice and international norms can create disputes at closing or in post‑completion price adjustments.

Key takeaways:

• Call‑in power. ÚOHS can now review concentrations that fall below standard notification thresholds if the target has significant competitive importance in the Czech market.
• Revised thresholds. Monetary turnover thresholds for mandatory merger notification have been recalibrated, catching some mid‑market deals that previously fell outside the regime.
• Manager liability. Individual directors and officers can face personal fines for competition‑law infringements, independent of corporate sanctions.
• Takeover updates. Disclosure requirements and squeeze‑out mechanics have been tightened, affecting both hostile and friendly bids.
• Criminal diversion. The 1 July 2026 criminal‑law amendment introduces non‑prosecution agreements for corporates that cooperate, creating new compliance incentives and diligence focus areas.
• Pre‑closing dividends. Permitted under Czech law but increasingly contentious; deal documentation must explicitly address distributions between signing and closing.

Immediate actions for buyers:

• Re‑assess whether planned acquisitions may be subject to the new call‑in power.
• Update SPA templates to include competition indemnities and expanded regulatory conditions precedent.
• Insist on pre‑closing covenants restricting extraordinary distributions.
• Verify target‑company D&O insurance coverage in light of new personal‑liability exposure.

Immediate actions for sellers:

• Prepare vendor due diligence packs addressing competition history and market‑share data.
• Negotiate carve‑outs for ordinary‑course dividends and clearly define working capital targets.
• Brief management on personal exposure under the new enforcement rules.
• Review takeover‑defence strategies against updated mandatory‑bid triggers.

Overview of Czech M&A Law Changes 2026, Statutory and Regulatory Detail

Understanding the legislative pipeline is essential for accurate risk assessment. The reforms relevant to Czech M&A in 2026 sit across multiple statutes and stages of the legislative process.

Competition law amendment

The draft amendment to the Act on the Protection of Competition has been described by leading practitioners as the most significant reform of Czech competition law in decades. The amendment introduces a targeted call‑in model, revises monetary notification thresholds, grants ÚOHS a market intervention instrument, and creates a framework for personal fines on managers. CMS has noted that earlier iterations of the amendment were not approved by the Czech Parliament, and the bill underwent revisions before re‑submission, deal teams should confirm the enacted text against the latest parliamentary record.

Takeover‑law updates

Chambers’ 2026 practice guide for Corporate M&A in the Czech Republic records targeted changes to mandatory bid triggers, enhanced disclosure obligations for bidders, and refined squeeze‑out procedures designed to align Czech practice more closely with EU norms. These changes are particularly relevant for public‑company transactions and minority‑shareholder exits.

Criminal‑law reform

The IBA has reported on a major amendment to the Czech Criminal Code effective 1 July 2026. The reform introduces a corporate criminal diversion regime, effectively a deferred prosecution model, that allows companies to negotiate non‑prosecution outcomes where they cooperate and remediate. This has direct M&A implications: buyers must assess whether a target has unresolved criminal exposure, and sellers must be prepared to disclose any pending diversion negotiations.

Legislative timeline

Merger Control and Czech Competition Enforcement 2026, New Powers and Practical Impact

The competition enforcement overhaul is the single most consequential element of the Czech M&A law changes 2026 for transaction planning. It affects filing obligations, clearance timelines and, for the first time, exposes individual managers to direct regulatory risk. Industry observers expect these changes to lengthen review periods for certain transactions and create additional uncertainty for deals that previously cleared without notification.

Call‑in model explained

Under the new framework, ÚOHS acquires the power to “call in” a concentration for review even where the parties’ turnover falls below the standard notification thresholds. The call‑in can be triggered where the target has significant competitive relevance in the Czech market, for example, an innovative start‑up with limited revenue but substantial market potential or competitive constraint. Rowan Legal has described this as a “new era of oversight” that moves Czech merger control closer to the model adopted in several other EU member states and advocated by the European Commission.

Key takeaways:

• The authority can initiate a call‑in within a defined period after closing or public announcement of a transaction.
• Parties cannot assume that sub‑threshold deals are safe from review.
• Early informal engagement with ÚOHS, a pre‑notification consultation, is likely to become standard practice for borderline transactions.

Quick action, Buyers: Include a regulatory‑risk condition precedent in the SPA that covers both mandatory filing and a potential call‑in. Sellers: Prepare a concise market‑position summary for the target to accelerate any informal review.

New monetary and market thresholds

The amendment recalibrates the turnover thresholds that trigger a mandatory merger notification. The revised framework is designed to capture mid‑market deals in sectors where market concentration is already high, while reducing the filing burden on clearly benign transactions.

The likely practical effect will be that straightforward, low‑concentration transactions clear faster, while deals involving targets with disproportionate market relevance face additional scrutiny, even if they fall below the headline thresholds.

Manager liability and corporate criminal law implications

For the first time in Czech competition enforcement, individual managers can be held personally liable for competition‑law infringements. Schoenherr has highlighted this as a paradigm shift that aligns Czech practice with more aggressive enforcement regimes across the EU. Personal fines can be imposed on directors and officers who participated in, authorised or failed to prevent an infringement.

Combined with the criminal‑law amendment effective 1 July 2026, which introduces corporate criminal diversion, the exposure for managers involved in M&A transactions is twofold: regulatory fines from ÚOHS for competition breaches, and potential criminal consequences at the corporate level if compliance failures are identified post‑acquisition.

Key takeaways:

• Buyers should insist on comprehensive management warranties covering competition compliance.
• D&O insurance coverage should be reviewed and, where necessary, topped up before closing.
• Sellers should brief key managers on personal exposure and consider protective indemnities in the SPA or in separate side agreements.

Czech Takeover Law 2026, Public Offers and Hostile Bid Mechanics

The takeover‑law amendments affect both bidders and target boards in public transactions. While the Czech market remains dominated by private M&A, the updated rules are directly relevant for listed‑company acquisitions, minority buy‑outs and any transaction involving a mandatory bid trigger.

Implications for bidders

Bidders face enhanced disclosure obligations at the point of announcing a public offer. The updated rules tighten the information that must be provided to the target’s shareholders, including detailed financing confirmations, strategic intentions for the target and employee‑impact statements. Squeeze‑out mechanics have been refined to provide greater clarity on pricing methodology and minority‑shareholder remedies.

Quick action, Bidders: Update offer‑document templates to reflect the expanded disclosure requirements. Budget additional time for regulatory review of offer documentation.

Implications for targets and defensive measures

Target boards benefit from slightly stronger disclosure‑driven protections but face stricter obligations in responding to bids. Defensive measures, particularly those involving asset disposals, share issuances or other value‑diluting actions, are subject to heightened scrutiny under the amended framework. Early indications suggest that target boards will need to document their decision‑making process more carefully to withstand potential shareholder challenges.

Quick action, Targets: Review board‑response protocols and prepare a defence playbook that complies with the updated takeover rules. Ensure independent legal advice is retained early in any approach scenario.

Deal Mechanics: Pre‑Closing Dividends, Working Capital and Purchase Price Adjustments

The gap between signing and closing in Czech deals can be several months, particularly where regulatory clearance is required. During this period, disputes over pre‑closing dividends and working capital adjustments are among the most common sources of deal friction.

Pre‑closing dividends, can they be paid?

Czech corporate law permits dividend distributions provided they satisfy the statutory balance‑sheet test, and recent practitioner analysis confirms that pre‑closing dividends remain legally permissible. However, the practical risk for buyers is significant: an unrestricted distribution before closing can erode the value of the target and undermine the economic assumptions on which the purchase price was based.

To manage this risk, deal documentation should include explicit pre‑closing covenants restricting distributions. Where the seller requires a distribution, the covenant should specify that it is only permitted if it passes the balance‑sheet test and the buyer has given prior written consent. Any disputed distribution should be covered by an escrow or holdback mechanism.

Sample covenant (illustrative):

“From Signing until Closing, the Target shall not declare, authorise or pay any dividend or other distribution to its shareholders except (a) with the prior written consent of the Buyer, and (b) only where such distribution would not cause the Target’s net assets to fall below the amount of its registered capital plus reserves required by law.”

Working capital adjustments, mechanics and dispute resolution

Working capital adjustments Czech deal teams negotiate typically follow a completion‑accounts or locked‑box model. Where the seller has conducted pre‑closing distributions, the working capital target must be adjusted to reflect the actual cash position of the business at closing. Failure to agree a clear adjustment mechanism is a frequent source of post‑completion disputes.

A well‑drafted working capital clause should include a defined target (agreed in advance, usually based on a normalised average), a measurement date (typically the closing date), a dispute‑resolution waterfall (accountant determination → expert determination → arbitration), and a clear timetable for preparation and review of completion accounts.

Sample waterfall (illustrative):

“Within 60 Business Days after Closing, the Buyer shall prepare and deliver to the Seller draft Completion Accounts. The Seller shall have 30 Business Days to review and raise objections. Unresolved items shall be referred to an Independent Accountant whose determination shall be final and binding (absent manifest error). If the Actual Working Capital exceeds the Target, the Buyer shall pay the surplus to the Seller; if it falls below, the Seller shall pay the shortfall to the Buyer.”

Practical negotiation playbook for buyers and sellers

• Buyers: Insist on a locked‑box structure where possible, it eliminates post‑closing price disputes. If a completion‑accounts model is required, negotiate a tight review window and agree the Independent Accountant’s identity in advance.
• Sellers: Push for a normalised working capital target that excludes seasonal or one‑off items. Negotiate a cap on the escrow amount and a sunset date for indemnity claims.
• Both parties: Include a specific schedule defining each line item that constitutes “working capital”, ambiguity in this definition is the primary driver of adjustment disputes in Czech M&A.

M&A Due Diligence Czech, What to Prioritise in 2026

The 2026 legislative changes create new priorities for M&A due diligence in the Czech Republic. Buyers should expand their diligence scope in three areas: competition exposure, takeover and governance risk, and criminal and manager liability.

Competition‑related diligence

The call‑in model means buyers can no longer rely solely on a turnover analysis to determine whether a filing is required. Diligence should include a detailed assessment of the target’s market position, competitive significance and any prior ÚOHS engagement.

Takeover and governance exposure

Where the target is a listed company or has minority shareholders, buyers must assess whether the acquisition triggers a mandatory bid obligation under the updated rules. This includes reviewing existing shareholder agreements, articles of association and any acting‑in‑concert arrangements.

Corporate governance and manager exposure

In light of the new personal liability for managers, buyers should verify whether any current or former managers of the target are subject to pending investigations, sanctions or compliance proceedings, and whether the target itself is engaged in any criminal diversion process under the 1 July 2026 amendment.

Due diligence checklist, 2026 priorities:

Cross‑Border M&A Czech, EU Interplay and Filing Strategy

Czech deals with a cross‑border dimension must navigate the interaction between Czech national merger control and the EU merger regulation administered by the European Commission. The 2026 changes amplify this complexity.

When EU filing may be required

If the parties’ combined worldwide and EU‑wide turnover exceeds the thresholds set out in the EU Merger Regulation, the transaction falls within the exclusive jurisdiction of the European Commission and a Czech national filing is not required. However, the Commission’s referral mechanisms (Articles 4(4), 4(5), 9 and 22 of the EU Merger Regulation) allow transactions to be referred between the Commission and national authorities, and the new Czech call‑in power could potentially interact with a referral request.

Parallel filings and contractual triggers

For cross‑border M&A involving Czech targets, the SPA should include a regulatory conditions precedent that covers all potentially applicable filings, Czech, EU, and any other national authority in jurisdictions where the parties operate. Reverse break fees (or “ticking fees”) should be calibrated to reflect the possibility that clearance may take longer if ÚOHS exercises its call‑in power or if a referral between the Commission and the Czech authority occurs.

Quick action, International deal teams: Map all filing obligations early in the diligence process. Include a regulatory matrix in the SPA schedules listing each authority, estimated timeline and the agreed long‑stop date for clearance.

Negotiation and Drafting Playbook, Sample Clauses

The following illustrative clauses reflect the drafting adjustments that industry observers expect will become standard in Czech M&A documentation during 2026. They should be adapted to the specific facts and negotiating dynamics of each transaction.

• Regulatory condition precedent: “Closing shall be conditional upon (a) clearance by ÚOHS (whether by approval, deemed approval, or expiry of the applicable review period without prohibition), and (b) confirmation that ÚOHS has not exercised its call‑in power within the applicable statutory period.”
• Competition warranty: “The Seller warrants that, to its knowledge, neither the Target nor any of its officers has been the subject of any investigation, inquiry, or proceeding by ÚOHS or any other competition authority, and that no officer has been subject to any personal fine or sanction for a competition‑law infringement.”
• Pre‑closing distribution covenant: “The Target shall not, and the Seller shall procure that the Target does not, declare, authorise or pay any dividend or other distribution between Signing and Closing without the Buyer’s prior written consent.”
• Escrow / holdback for disputed distributions: “An amount equal to [●]% of the Purchase Price shall be deposited into the Escrow Account at Closing and shall be available to satisfy any indemnity claim arising from a Prohibited Distribution or Working Capital Shortfall, subject to a survival period of [18] months from Closing.”
• Working capital adjustment: “If the Actual Working Capital as at the Measurement Date is less than the Target Working Capital, the Seller shall pay to the Buyer an amount equal to the shortfall within 10 Business Days of the Independent Accountant’s determination.”
• Reverse break fee (regulatory failure): “If Closing does not occur by the Long‑Stop Date solely because the Regulatory Condition has not been satisfied (including as a result of a call‑in by ÚOHS), the Buyer shall pay the Seller a break fee of [●] as the Seller’s sole and exclusive remedy.”

Conclusion, Preparing for Czech M&A Law Changes 2026

The Czech M&A law changes 2026 represent the most significant overhaul of the Czech deal environment in over a decade. The introduction of the call‑in model, personal manager liability, revised notification thresholds and a corporate criminal diversion regime collectively require every deal team operating in the jurisdiction to update its playbook, from initial diligence through to SPA drafting and post‑closing integration.

Buyers who integrate these changes into their standard operating procedures early will minimise deal risk and avoid costly delays. Sellers who proactively prepare vendor due diligence, brief management and adapt their negotiation position will protect deal value and accelerate clearance.
