Poland Merger Control Thresholds 2026: Uokik Triggers, Tests, Timelines and Gun-jumping Fines

Understanding the Poland merger control thresholds is the single most important step for any deal team contemplating an acquisition, merger or joint venture that touches the Polish market. Under the Polish Competition and Consumer Protection Act, the Office of Competition and Consumer Protection (UOKiK) must be notified of any concentration that meets specific turnover tests, EUR 1 billion worldwide or EUR 50 million in Poland, before closing can occur. The 2 April 2025 UOKiK guidance on extraterritorial joint ventures has refined when foreign-to-foreign transactions trigger a filing obligation, while the authority’s intensified enforcement posture throughout 2026 has made gun-jumping fines a concrete commercial risk rather than a theoretical one.

This guide delivers the practical compliance checklist that in-house counsel and transaction advisers need: how to calculate the thresholds, how to navigate the Phase I and Phase II review process, and how to avoid sanctions that can reach up to 10 % of group turnover.

Executive Summary: Key Takeaways for Deal Teams

Before diving into the detail, the following five points capture the essential rules governing merger control in Poland:

• Two turnover gates. A UOKiK merger notification is mandatory when the combined worldwide turnover of all undertakings concerned exceeds EUR 1,000,000,000 or the combined turnover generated in Poland exceeds EUR 50,000,000 in the financial year preceding the notification.
• EUR 10 million de‑minimis. Certain concentrations, notably some asset acquisitions and joint-venture formations, may be exempt where the target’s or the JV participants’ Polish turnover does not exceed EUR 10,000,000.
• Effects doctrine for foreign JVs. Following the 2 April 2025 UOKiK guidance, a foreign-to-foreign JV can still require a Poland filing if it produces or is likely to produce effects on the Polish market.
• Timelines. Phase I review runs one to two months from a complete filing; Phase II market investigation adds several further months, with complex cases reaching four to nine months or more in total.
• Gun-jumping fines. Closing before clearance, or failing to notify at all, exposes parties to fines of up to 10 % of annual turnover, plus corrective orders including potential unwinding of the transaction.

Notification Thresholds and Tests in Poland, The Numbers and How to Calculate Them

The statutory basis for the UOKiK notification thresholds is found in the Competition and Consumer Protection Act of 16 February 2007 (as amended). Notification is required for any “concentration”, defined broadly to cover mergers, acquisitions of control, and the creation of a joint undertaking that performs the functions of an autonomous economic entity on a lasting basis, whenever at least one of the two turnover tests is satisfied in the financial year preceding the concentration.

Test 1: Global Turnover, EUR 1 Billion

If the combined aggregate worldwide turnover of all undertakings participating in the concentration exceeds EUR 1,000,000,000, notification is triggered regardless of how much revenue any party earns in Poland. “All undertakings participating” means the acquiring and target groups (or all JV parents), calculated on a consolidated basis. Turnover encompasses revenue from the sale of products and services in the ordinary course of business, net of VAT and other directly related taxes.

Test 2: Polish Turnover, EUR 50 Million

Alternatively, notification is required where the combined turnover of all undertakings concerned generated in the territory of Poland exceeds EUR 50,000,000. This is the test most relevant to mid-market transactions that may fall below the global gate but still have meaningful Polish operations. “In Poland” means revenue from sales to Polish customers or through Polish establishments.

Group Aggregation Rules

When calculating turnover under either test, the figures must be aggregated at the level of the entire capital group, parents, subsidiaries and any entities jointly controlled by the undertaking concerned. Intra-group turnover is excluded. Where the acquirer is a private equity fund, the UOKiK typically looks at the fund vehicle’s wider portfolio companies, not merely the direct purchaser entity.

Currency Conversion

Since the thresholds are stated in euro, turnover reported in Polish złoty (PLN) or other currencies must be converted. The standard approach, consistent with UOKiK practice and International Competition Network guidance, is to use the average exchange rate published by the National Bank of Poland (NBP) for the relevant financial year.

The EUR 10 Million De‑Minimis Rule

Not every transaction that clears the EUR 1 billion or EUR 50 million gate automatically requires a filing. Under a targeted de‑minimis exemption, a concentration involving the acquisition of part of an undertaking’s assets (e.g., a single business division or product line) may be exempt if the turnover generated by those assets in Poland did not exceed EUR 10,000,000 in either of the two financial years preceding the notification. A comparable carve-out can apply to certain joint ventures where none of the JV participants individually generated more than EUR 10,000,000 in Poland. Practitioners should apply this exemption with care, it is narrowly interpreted by UOKiK, and incorrect reliance on it offers no protection against gun-jumping liability.

Worked Examples

Example 1, Cross-border share purchase. A German industrial group (worldwide turnover EUR 4 billion, Polish turnover EUR 30 million) acquires 100 % of a French manufacturer (worldwide turnover EUR 200 million, Polish turnover EUR 25 million). Combined worldwide turnover: EUR 4.2 billion (exceeds EUR 1 billion). Combined Polish turnover: EUR 55 million (also exceeds EUR 50 million). Both tests are met. A UOKiK merger notification is required.

Example 2, Small-target exemption assessment. A UK private equity sponsor (fund group worldwide turnover EUR 900 million, Polish turnover EUR 5 million) acquires the assets of a Polish logistics division with turnover of EUR 8 million in Poland. Combined worldwide turnover: below EUR 1 billion. Combined Polish turnover: EUR 13 million, below EUR 50 million. Neither primary test is met. No notification is required. (The de‑minimis question does not even arise because the main thresholds are not crossed.)

Example 3, JV with de‑minimis analysis. Two US companies (each with worldwide turnover well above EUR 1 billion) form a JV to develop software. Neither parent generates more than EUR 9 million in Poland. Combined worldwide turnover exceeds EUR 1 billion. However, because each participant’s Polish turnover is below EUR 10 million, the JV de‑minimis may apply, provided the JV itself is not expected to immediately generate Polish turnover above that floor. This scenario demands careful factual analysis and, where doubt exists, a pre-notification consultation with UOKiK.

Extraterritorial JVs and the 2025 UOKiK Guidance, When Foreign-to-Foreign Matters

The question of whether a purely foreign transaction requires a Poland filing has long created uncertainty. On 2 April 2025, UOKiK published guidance clarifying the application of the effects doctrine to foreign joint-venture concentrations, a development that narrows the filing obligation for JVs with no genuine nexus to the Polish market, while confirming that the authority retains jurisdiction wherever effects are present.

How UOKiK Tests Effects

Under the 2025 guidance, UOKiK applies a fact-based analysis centred on whether the concentration “produces or is likely to produce effects in the territory of the Republic of Poland.” The key indicators include:

• Whether any JV parent or the JV entity itself generates revenue from Polish customers or through Polish distribution channels.
• Whether the JV will hold assets (licences, production facilities, IP registrations) in Poland.
• Whether the JV’s product or service offering targets the Polish market, even if sales have not yet commenced.
• Whether competitive conditions in a Polish-relevant market would be altered (e.g., by combining competing suppliers’ activities).

Where none of these indicators is present, the guidance states that UOKiK will not treat the JV as a notifiable concentration, even if the turnover thresholds are numerically satisfied by reason of the parents’ unrelated Polish revenues. Industry observers expect this approach to reduce the number of unnecessary filings by foreign sponsors with incidental Polish portfolio exposure.

Practical Drafting to Avoid Triggering a Poland Filing

Where parties intend to rely on the extraterritorial JV exemption in Poland, transaction documents should be drafted to avoid signals of Polish market targeting. Practical steps include limiting JV board observer rights so that parents do not exercise decisive influence over Polish activities, excluding Polish territories from the JV’s initial business plan, and inserting standstill covenants that explicitly prevent any Polish commercial activity before the parties have confirmed the filing position. These precautions are not a substitute for legal analysis but can strengthen the factual record if UOKiK later queries the parties’ assessment.

Filing Process, Merger Filing Poland Timelines, and Phase I / Phase II UOKiK Procedure

Once the parties determine that notification is required, the filing process under UOKiK follows a structured sequence. Understanding the practical timeline, not just the statutory clock, is essential for deal certainty and SPA conditionality drafting.

Pre-Notification (Optional but Recommended)

UOKiK encourages parties to engage in informal pre-notification consultations, particularly for complex or novel transactions. There is no statutory framework for these discussions, but in practice they allow the filing party to identify likely information requests, discuss market definitions and flag potential competition concerns before the formal clock starts. A well-prepared pre-notification phase can reduce Phase I duration significantly.

Formal Notification

The notification is filed by the undertaking acquiring control (or, in a merger/JV, jointly by the merging parties or JV parents). The standard notification form requires detailed information on the parties’ group structures, turnover breakdowns (worldwide and in Poland), descriptions of affected markets, competitive overlaps, and vertical/conglomerate relationships. Supporting documents include the SPA or JV agreement, audited financial statements, and structure charts. The ICN merger notification form template for Poland provides a useful reference for the disclosure items expected.

Phase I Review

Once UOKiK confirms that the notification is complete, the Phase I clock starts. The statutory period for Phase I is one month, extendable to two months in cases where UOKiK conducts market testing or issues requests for information (RFIs). In practice, the completeness confirmation itself can take several weeks if the initial submission is deficient, so parties should plan for a total Phase I window of roughly six to eight weeks from the date of first filing.

Phase II Market Investigation

If UOKiK identifies serious competition concerns during Phase I, it will open a Phase II in-depth investigation. Phase II has a statutory duration of four months but may be extended further in particularly complex cases. RFIs during Phase II can be extensive, requiring market data, internal strategy documents and customer-facing correspondence. Remedy discussions, structural or behavioural, typically commence mid-way through Phase II.

Deal teams should build these merger filing Poland timelines into SPA long-stop dates. A common pitfall is underestimating the time from signing to the start of the statutory clock, the completeness-check period is not counted against the Phase I deadline.

Gun-Jumping Fines in Poland, Sanctions and Remedial Powers

“Gun-jumping” refers to either failing to notify a concentration that meets the Poland merger control thresholds or implementing a notifiable transaction before obtaining UOKiK clearance. Both violations carry substantial consequences.

Financial Penalties

Under the Competition and Consumer Protection Act, UOKiK may impose a fine of up to 10 % of the infringing undertaking’s turnover in the financial year preceding the decision. The fine applies to each undertaking that participated in the gun-jumping, meaning that both buyer and seller (or all JV parents) can be penalised separately.

Corrective Orders

Beyond fines, UOKiK holds the power to order the reversal of a completed concentration. This can mean forced divestiture of acquired shares or assets, dissolution of a JV, or the imposition of behavioural conditions designed to restore pre-concentration competitive dynamics. In practice, corrective orders are rare but their availability strengthens UOKiK’s negotiating position in remedy discussions.

Enforcement Examples

UOKiK has demonstrated a willingness to act. The authority has investigated and imposed gun-jumping fines in cases involving energy distribution and industrial gas sectors, sending a clear signal that failure to file is not treated as a mere procedural oversight. Early indications suggest that UOKiK’s enforcement focus in 2026 extends to monitoring private equity bolt-on acquisitions where the filing obligation was overlooked during fast-track deal execution.

How to Mitigate Risk

The most effective protection is a robust pre-signing threshold screening process, the checklist in Section 7 below. Where notification is required, hold-separate arrangements and clean-team protocols should prevent any transfer of commercially sensitive information or exercise of control before clearance.

Information Requests, Remedies and Conditional Clearances

UOKiK has broad powers to request information from the notifying parties and from third parties (competitors, customers, suppliers) during both Phase I and Phase II. Typical requests cover market share data, pricing structures, distribution arrangements and internal strategic planning documents.

When the authority identifies competition concerns that can be resolved without blocking the transaction, it offers parties the opportunity to propose remedies. These fall into two categories:

Where a transaction also triggers an EU-level filing (under the EU Merger Regulation or the Foreign Subsidies Regulation), coordination between UOKiK and the European Commission is standard. UOKiK may defer certain aspects of its analysis pending the Commission’s decision, or vice versa when the Commission refers a case back to the national authority. Deal teams running parallel filings should ensure timeline alignment across jurisdictions.

Deal Checklist, Pre-Due-Diligence to Closing

The following action list translates the Poland merger control thresholds and procedural rules into a practical step-by-step workflow for transaction counsel.

1. Early threshold screening. At term-sheet stage, gather consolidated worldwide and Polish turnover for all parties (including portfolio companies for PE acquirers). Convert to EUR using the NBP average rate for the last completed financial year. Compare against EUR 1 billion (global) and EUR 50 million (Poland).
2. De‑minimis assessment. If thresholds are met, check whether the EUR 10 million de‑minimis applies to the specific transaction type (asset purchases, JVs). Document the analysis.
3. Effects doctrine analysis (for foreign transactions). Apply the 2025 UOKiK guidance to assess whether any Poland effects exist. Prepare a written memo for the file.
4. SPA drafting discipline. Include a merger-control condition precedent with a realistic long-stop date (minimum 3 months for Phase I; 9+ months if Phase II is possible). Draft clean-team and hold-separate protocols. Avoid granting the acquirer board-appointment rights or operational control before clearance.
5. Pre-notification engagement. For complex transactions, engage informally with UOKiK to discuss market definitions and potential concerns before filing.
6. Prepare the notification package. Assemble all required documents: SPA/JV agreement, capital group structure chart, last two years’ audited financials with turnover breakdown (group and Poland), market descriptions, competitor/customer lists, and board minutes authorising the transaction.
7. File and manage the clock. Submit the formal notification and track completeness-check timing. Respond promptly to any RFIs, each delay pushes the statutory clock back.
8. Remedy readiness. If Phase II is opened, prepare remedy proposals early. Structural remedies require identification of a viable buyer and a realistic implementation timeline.
9. Closing mechanics. Only proceed to closing after receipt of the unconditional or conditional clearance decision. Record the decision reference number in closing documents.

Reporting Obligations by Transaction Type

Filing costs are modest by international standards, UOKiK charges a statutory filing fee of PLN 15,000 (approximately EUR 3,500). External adviser fees for preparation and management of a straightforward Phase I filing typically range from EUR 10,000 to EUR 30,000 depending on complexity, with Phase II matters commanding significantly higher budgets. Parties should also factor in management time for data-gathering and potential RFI responses.

Conclusion and Next Steps

Navigating the Poland merger control thresholds requires precision at every stage, from initial turnover screening through to closing. The consequences of miscalculation are not theoretical: gun-jumping fines of up to 10 % of turnover, mandatory unwinding of completed deals and lasting reputational damage with UOKiK are all within the authority’s enforcement toolkit. Deal teams should integrate the threshold tests and checklist above into their standard transaction workflow and seek specialist Polish competition law counsel early in the process.
