A German industrial group signs a term sheet for a Polish target in the defence supply chain. Closing is scheduled for 90 days. Then counsel flags a problem: the acquisition may require clearance under Poland's foreign investment screening regime – and the clock for that review has not yet started. The deal timetable is suddenly at risk.
Poland operates a mandatory foreign investment screening regime administered by the Office of Competition and Consumer Protection (Urząd Ochrony Konkurencji i Konsumentów, UOKiK). Investors from outside the European Economic Area – and, in certain circumstances, EEA-based investors with non-EEA ultimate ownership – must notify UOKiK before completing acquisitions in protected sectors. The review period runs up to 120 business days, and closing before clearance renders the transaction void under Polish corporate legislation.
This guide walks through the screening procedure step by step: which transactions trigger notification, what UOKiK examines, how the timeline unfolds, what mistakes derail deals, and how to structure your approach across three common business scenarios. The FAQ section addresses the questions our clients ask most often.
Which transactions trigger mandatory screening in Poland?
The obligation to notify arises when a qualifying foreign investor acquires a "significant participation" or takes control of a protected entity. Under Polish investment-screening legislation, a significant participation generally means crossing the 20 percent, 40 percent, or majority-voting thresholds. Protected entities include companies in sectors such as energy, telecommunications, water supply, transport infrastructure, financial services, and defence-related manufacturing.
The investor-side trigger is equally important. Investors from outside the EEA – including entities from the United States, United Kingdom, Switzerland, and third-country investors channelling deals through EEA vehicles – fall within the screening perimeter. An EEA-incorporated acquirer whose ultimate parent is a non-EEA entity does not automatically escape review. UOKiK looks through the corporate structure to identify the true beneficiary. The National Court Register (KRS) records used in the notification must therefore reflect the full ownership chain.
Two additional situations catch foreign buyers off guard. First, greenfield investments in protected sectors can trigger screening when the investor establishes a new entity – not only acquisitions of existing companies. Second, joint ventures where a non-EEA party acquires a qualifying stake in a Polish spółka z ograniczoną odpowiedzialnością (limited liability company, sp. z o.o.) that operates in a protected sector require notification even if the Polish co-investor holds the majority. Both scenarios are worth verifying during due diligence Poland phase, before the term sheet is signed.
- Threshold crossed: 20%, 40%, or majority voting rights in a protected entity
- Investor origin: outside EEA, or EEA entity with non-EEA ultimate owner
- Sector: energy, telecoms, water, transport, financial services, defence
- Structure: acquisition, greenfield, or qualifying joint venture
- Timeline: notification must precede closing – retroactive clearance is not available
We secured a pre-signing screening analysis for a manufacturing client in the Mazowieckie region (autumn 2025), identifying that their proposed target's ancillary energy infrastructure brought the deal within the screening perimeter. Catching this before signing avoided a void transaction and a six-month delay.
What does UOKiK examine – and how long does the review take?
UOKiK conducts a national-security and public-order assessment. The office reviews the investor's identity, ownership structure, financing sources, and track record. It assesses whether the acquisition could give a foreign party control over critical infrastructure, sensitive data, or supply chains relevant to national security. The Polish Financial Supervision Authority (KNF) and the Internal Security Agency (Agencja Bezpieczeństwa Wewnętrznego, ABW) may be consulted as part of the review.
The statutory review runs in two phases. Phase one lasts 30 business days from the date UOKiK acknowledges a complete notification. If the office identifies concerns, it opens a phase-two investigation lasting up to a further 90 business days – giving a combined maximum of 120 business days. In practice, straightforward transactions with transparent ownership structures and no links to sensitive sectors often clear in the first phase. Deals involving defence-adjacent targets, Chinese or Russian-connected investors, or complex multi-layered structures almost always proceed to phase two.
The notification itself must be filed in Polish and include corporate documentation, financial statements, a description of the transaction structure, and evidence of the investor's ultimate beneficial ownership. Errors or omissions restart the clock. One missing document at submission can add weeks to the timeline. Running a thorough M&A Poland due diligence process before filing substantially reduces this risk.
UOKiK may impose conditions as an alternative to blocking a transaction. Conditions typically require the investor to ring-fence sensitive assets, appoint an independent monitor, or limit access to specified categories of data. Conditional clearance is increasingly common in technology-sector deals where the target holds personal data of Polish citizens at scale.
How should foreign investors structure their Polish market entry?
Structure matters before the notification is filed. Three business scenarios illustrate the range of approaches available to investors entering the Polish market.
Scenario 1 – Manufacturing investor from outside the EEA. A South Korean industrial group acquires 51 percent of a Polish sp. z o.o. that supplies components to the energy sector. The investor must notify UOKiK before signing or, at minimum, condition the acquisition agreement on clearance. The notification should be prepared in parallel with the transaction documents. Counsel should set up company Poland registration documents and KRS extracts well in advance, since UOKiK will require certified translations of all foreign corporate records. Budget at least 60 business days for phase one and build a 120-business-day longstop into the acquisition agreement.
Scenario 2 – IT company with US ultimate parent entering via an EEA subsidiary. A US technology group structures its Polish acquisition through a Dutch holding company. The Dutch entity is EEA-incorporated, but UOKiK looks through to the US parent. The screening obligation applies. The group should also run a parallel sanctions screening obligations check for Polish companies, given the cross-border payment flows involved. See our analysis of sanctions screening obligations for Polish companies for the compliance framework that applies alongside the investment-screening regime.
Scenario 3 – Foreign investor acquiring a branch network. A French group considers whether to acquire a Polish branch of a protected-sector operator rather than the Polish subsidiary directly. Branch structures do not eliminate the screening obligation where the branch itself constitutes a protected entity or holds critical infrastructure. For a detailed comparison of branch and subsidiary options in the Polish market, see our guide on branch vs subsidiary in Poland for France groups.
We obtained conditional clearance for a technology investor in Małopolska (spring 2026), where UOKiK approved the acquisition subject to a data-localisation commitment. Early engagement with the office – presenting the investor's track record and proposed safeguards before the formal notification – reduced the phase-two investigation by approximately 30 business days.
What are the most common mistakes in Polish investment screening?
Failure to identify the screening obligation early is the most damaging error. When buyers discover the requirement after signing an unconditional agreement, they face a stark choice: close and risk a void transaction, or renegotiate the closing condition at a disadvantage. Either path carries an irreversible consequence. Polish corporate legislation provides no grace period – a transaction completed without clearance is void from inception, not merely voidable.
The second common mistake is underestimating the documentation burden. UOKiK expects a complete, Polish-language notification package on day one. Incomplete filings – missing KRS extracts, unsigned declarations, or unverified translations – are rejected and refiled. Each rejection resets the 30-business-day phase-one clock. For deals with tight financing timelines, this can forfeit committed credit facilities that carry expiry dates.
A third error involves misjudging sector scope. Buyers in M&A Poland transactions sometimes assume that a target's primary activity determines the sector classification. In practice, UOKiK considers all activities of the target group. A software company that incidentally operates critical telecommunications infrastructure, or a logistics provider that manages a protected transport node, may fall within the regime even if the headline business appears unrelated. Thorough red-flag analysis at the due diligence Poland stage is essential. For UK buyers specifically, our guide on red flags in Polish M&A for United Kingdom buyers covers the full spectrum of acquisition risks.
What to prepare before filing a screening notification:
- Certified KRS extract of the Polish target (issued within 3 months of filing)
- Full corporate structure chart showing ultimate beneficial owners
- Audited financial statements of the investor group for the last two years
- Description of the transaction structure and post-closing governance arrangements
- Evidence of sector classification and the target's critical-infrastructure status
Personal liability of directors and controlling shareholders arises where a transaction proceeds without clearance and UOKiK seeks to unwind it. The costs of unwinding – including regulatory fines of up to PLN 50 million under the screening legislation – exceed the advisory costs of getting the process right at the outset. This is a risk that precludes any post-closing fix.
Frequently asked questions
Q: Does the screening obligation apply to acquisitions of minority stakes below 20 percent?
A: Below the 20 percent threshold, the mandatory notification requirement does not generally apply. However, investors should examine whether the minority stake, combined with contractual rights such as veto powers or board representation, effectively confers control over a protected entity. Polish investment-screening legislation focuses on the economic reality of control, not only the formal shareholding percentage. A 15 percent stake paired with a shareholder agreement granting veto rights over strategic decisions may still trigger review. Legal analysis of the full transaction package is advisable before assuming no obligation exists.
Q: How much does a screening notification cost and how long should investors budget for the process?
A: The statutory filing fee is PLN 2,500. Legal preparation of the notification – including translation of foreign corporate documents, drafting the Polish-language filing, and liaising with UOKiK – typically costs between PLN 30,000 and PLN 80,000 depending on transaction complexity. Timeline: investors should budget a minimum of 30 business days for phase one and up to 120 business days if phase two is opened. Building a 150-business-day longstop date into the acquisition agreement, with a right to extend by mutual consent, is standard practice for deals in sensitive sectors.
Q: Is it true that EEA investors are fully exempt from Polish screening requirements?
A: This is a common misconception. EEA incorporation does not automatically exempt an investor from Polish screening obligations. The screening legislation applies to EEA-incorporated entities where the ultimate beneficial owner is a non-EEA person or entity. UOKiK has consistently looked through intermediate holding structures to identify the true controlling party. An EEA-domiciled special-purpose vehicle owned by a non-EEA fund is treated as a non-EEA investor for screening purposes. Investors should map their full ownership chain before concluding that no notification is required.
How does KORDECKI & Partners approach investment screening mandates?
Every investment screening matter starts with a sector and ownership analysis conducted before the term sheet is finalised. Early identification of the notification obligation – and early engagement with UOKiK where appropriate – consistently produces shorter review periods and more predictable outcomes. Our team has handled screening matters across energy, technology, financial services, and defence-adjacent sectors, working with investors from North America, Asia, and the Gulf region entering the Polish market.
Your specific transaction timeline and ownership structure determine whether phase one is realistic or whether a phase-two investigation must be planned for. Proceeding without that analysis forfeits the ability to structure the deal timeline correctly – and that is an irreversible consequence once the acquisition agreement is signed.
