Brexit Impact on Cross-Channel Acquisitions (UK-EU)

The United Kingdom's departure from the European Union has created a fundamentally different market for cross-channel acquisitions, transactions where a UK-based acquirer purchases an EU business, or vice versa. What were once seamless intra-EU transactions governed by harmonized regulations, free movement principles, and the Parent-Subsidiary Directive are now cross-border deals that must manage a new and evolving framework of bilateral agreements, regulatory divergence, and additional compliance requirements. For search fund entrepreneurs and acquisition-minded professionals operating across the English Channel, understanding these changes is critical to structuring successful cross-border deals.

The post-Brexit regulatory environment

Since January 1, 2021, when the transition period ended, the UK has been a “third country” in relation to the EU. This seemingly simple change of status has cascading effects across virtually every area of law and regulation that affects acquisitions. The UK-EU Trade and Cooperation Agreement (TCA), concluded on December 24, 2020, provides a baseline framework for the economic relationship, but it is far less thorough than EU membership. The TCA ensures tariff-free and quota-free trade in goods (subject to rules of origin), but it provides only limited coverage for services, financial regulation, and professional qualifications.

For acquirers, the key practical reality is that cross-channel transactions now require a dual regulatory analysis: one for the UK regime and one for the relevant EU Member State regime. EU directives that previously applied uniformly (including those on mergers, company law, competition, data protection, and employment) no longer extend to the UK, and the UK's domestic equivalents may diverge over time. This regulatory bifurcation creates both complexity and opportunity.

Tax treaty and withholding tax implications

One of the most significant post-Brexit changes for cross-channel acquisitions concerns the tax treatment of dividends, interest, and royalties flowing between UK and EU entities. Prior to Brexit, the EU Parent-Subsidiary Directive eliminated withholding taxes on dividend distributions between qualifying EU parent and subsidiary companies. The Interest and Royalties Directive similarly eliminated withholding taxes on interest and royalty payments between associated companies in different Member States. These directives no longer apply to UK-EU flows.

Bilateral tax treaty network

The UK maintains an extensive network of bilateral tax treaties with EU Member States. These treaties generally reduce (though do not always eliminate) withholding taxes on cross-border payments. However, the withholding tax rates under bilateral treaties are often higher than the zero rates that applied under the EU directives. For example, the UK-France treaty permits a 0% withholding on dividends for qualifying holdings, while the UK-Germany treaty allows 5% or 15% depending on the ownership threshold. The UK-Italy treaty provides for 5% or 15% withholding on dividends. Each bilateral treaty must be analyzed individually.

For acquirers structuring holding company arrangements across the UK-EU divide, the loss of the EU directives may increase the effective tax cost of repatriating profits. This must be modeled carefully during the deal evaluation phase. In some cases, the additional withholding tax cost may justify alternative structures, such as locating the holding company in an EU Member State with favorable treaty rates to both the UK and the target jurisdiction.

UK Diverted Profits Tax and STTR

The UK's Diverted Profits Tax (DPT), which imposes a 25% charge on profits artificially diverted from the UK, remains relevant for EU acquirers with UK operations. Additionally, the OECD's Subject to Tax Rule (STTR), being implemented through bilateral treaty amendments, may affect certain cross-channel payment flows where the recipient jurisdiction taxes the income at a nominal rate below 9%. Acquirers should assess whether their post-acquisition structures could trigger DPT or STTR exposure.

Data transfers and UK adequacy

Cross-channel acquisitions inevitably involve the transfer of personal data between the UK and the EU. The EU General Data Protection Regulation (GDPR) restricts the transfer of personal data to countries outside the European Economic Area unless that country ensures an “adequate” level of data protection. On June 28, 2021, the European Commission adopted an adequacy decision for the UK, recognizing the UK's data protection framework (the UK GDPR and Data Protection Act 2018) as providing an adequate level of protection.

However, the adequacy decision is not permanent. It includes a sunset clause requiring periodic review, and it can be revoked if the UK's data protection standards diverge materially from EU norms. The UK government has signaled interest in reforming its data protection framework to reduce compliance burdens on businesses, which could potentially trigger a revocation of adequacy. Acquirers completing cross-channel deals should consider this risk in their data privacy due diligence and develop contingency plans (such as Standard Contractual Clauses or Binding Corporate Rules) for the scenario where adequacy is lost.

Practical data transfer considerations

• Customer databases: If the acquisition involves transferring customer personal data between UK and EU entities, confirm that the adequacy decision covers the categories of data involved and that the transfer mechanism is documented and compliant.
• Employee data: Post-acquisition HR integration often requires sharing employee data across borders. Map the data flows and ensure that each transfer has a valid legal basis under both UK GDPR and EU GDPR.
• Due diligence data rooms: The due diligence process itself involves transferring significant volumes of data. Ensure that virtual data room providers and the data transfer mechanisms used during due diligence comply with applicable data protection requirements.

Immigration and work permits

The end of free movement between the UK and the EU has introduced immigration barriers that affect cross-channel acquisitions in several ways. Pre-Brexit, EU nationals could live and work in the UK (and vice versa for UK nationals in the EU) without requiring visas or work permits. Post-Brexit, the following frameworks apply.

UK immigration for EU nationals

EU nationals wishing to work in the UK must now apply through the UK's points-based immigration system. The most relevant route for acquisition-related personnel is the Skilled Worker visa, which requires sponsorship by a UK employer, a job offer at an appropriate skill level, and a minimum salary threshold. The process takes several weeks and involves employer compliance obligations, including maintaining a sponsor license.

EU immigration for UK nationals

UK nationals wishing to work in EU Member States are subject to each Member State's national immigration rules for third-country nationals. There is no EU-wide work permit; each country has its own requirements, processing times, and conditions. This is particularly relevant for acquirers who plan to deploy UK-based management to oversee EU operations post-acquisition, or who need to send integration teams on extended assignments.

Impact on management transitions

For ETA transactions in Europe where a UK-based searcher acquires an EU business (or an EU-based searcher acquires a UK target), the founder's right to live and work in the target's jurisdiction is no longer automatic. Immigration planning must begin early in the deal process, as visa processing times can affect the closing timeline and the acquirer's ability to take operational control on day one.

Regulatory divergence and its opportunities

Since Brexit, the UK and EU regulatory frameworks have begun to diverge in several areas relevant to acquisitions. This divergence creates complexity but also opportunities for acquirers who understand the differences and can exploit them strategically.

• Financial services regulation: The UK has adopted the Edinburgh Reforms and other measures aimed at making London more competitive as a financial center. These include reforms to the listing regime, insurance regulation (Solvency UK), and bank capital requirements. For acquirers of financial services businesses, regulatory regime differences affect licensing requirements, capital adequacy, and the ability to passport services across the UK-EU border (which is no longer possible post-Brexit without equivalence determinations).
• Subsidy control: The UK has replaced EU State Aid rules with its own Subsidy Control Act 2022, which takes a different approach to controlling government subsidies. Acquirers evaluating targets that benefit from government grants, tax incentives, or other forms of state support should understand the applicable regime and any conditions attached to the support.
• Product standards and conformity: The UK is developing its own product standards regime (UKCA marking) to replace EU CE marking, though the transition has been extended multiple times. For acquirers of manufacturing or distribution businesses, dual compliance with both UKCA and CE standards may be required to serve both markets, increasing compliance costs but also creating barriers that protect incumbents.
• Competition and merger control: The UK Competition and Markets Authority (CMA) operates independently of the European Commission. Cross-channel acquisitions above the relevant thresholds may require regulatory clearance from both the CMA and the European Commission, with each authority applying its own substantive test and timeline.

Trade agreement implications for operating businesses

The TCA provides for tariff-free trade in goods between the UK and EU, but this is subject to rules of origin requirements. To qualify for zero tariffs, goods must demonstrate sufficient UK or EU content (depending on the direction of trade). For acquirers of manufacturing or distribution businesses, this means that supply chains relying on components from third countries may not qualify for preferential tariff treatment, even if final assembly occurs in the UK or EU.

Beyond tariffs, the TCA does not eliminate customs procedures. All goods moving between the UK and EU are now subject to customs declarations, border checks, sanitary and phytosanitary (SPS) inspections for food and agricultural products, and VAT at the border. These requirements add cost, complexity, and delay to cross-channel supply chains. Acquirers evaluating businesses with significant UK-EU goods trade should assess the impact on working capital (customs duties and VAT must be paid at import), delivery times, and customer experience.

The TCA's coverage of services is limited. While it includes some provisions on market access for services, it does not replicate the single market's freedom to provide services. Professional qualifications are not automatically recognized across the UK-EU border, which affects businesses in professional services, healthcare, and technical fields. Acquirers evaluating targets in the best jurisdictions for acquisitions should factor these limitations into their market analysis.

Opportunities for acquirers

Despite the additional complexity, Brexit has created genuine opportunities for well-prepared acquirers operating across the English Channel.

• Valuation discounts: Uncertainty and increased regulatory complexity have depressed valuations for some cross-channel businesses, particularly those heavily dependent on UK-EU trade. Acquirers with the expertise to manage the new regulatory environment can acquire businesses at attractive valuations that reflect a complexity discount rather than fundamental value impairment.
• Operational restructuring: Businesses that have not yet adapted their operations to the post-Brexit reality present restructuring opportunities. An acquirer who can optimize supply chains, establish dual-market compliance capabilities, and restructure cross-border arrangements can unlock significant value.
• Market consolidation: Increased compliance costs and regulatory complexity disproportionately burden smaller businesses. This creates opportunities for acquirers to consolidate fragmented markets by acquiring businesses that lack the scale or resources to manage cross-channel compliance efficiently.
• UK as a gateway:For non-EU acquirers, the UK offers a common-law, English-speaking jurisdiction with a well-developed M&A infrastructure, flexible employment law, and competitive corporate tax rates. A UK acquisition can serve as a platform for subsequent expansion into EU markets, or vice versa.
• Talent arbitrage: Post-Brexit immigration rules have created skill shortages in some UK sectors, while EU labor markets remain accessible to EU-based businesses. Acquirers who can deploy talent flexibly across both markets working within the new immigration frameworks , have a competitive advantage over those limited to a single labor pool.

Due diligence considerations specific to cross-channel deals

Beyond the standard due diligence checklist, cross-channel acquisitions require additional investigation in several areas.

1. Supply chain exposure:Map the target's supply chain to identify all cross-channel goods and services flows. Quantify the customs, tariff, and compliance costs arising from each flow. Assess whether rules of origin requirements are met for tariff-free treatment.
2. Customer concentration risk:Evaluate the proportion of the target's revenues derived from cross-channel customers. If significant, assess how Brexit-related trade barriers affect customer relationships, delivery times, and competitive positioning.
3. Regulatory licensing: Identify all regulatory licenses, permits, and authorizations that the target holds. Determine whether any licenses are based on EU passporting rights that no longer extend to the UK, and assess the cost and timeline for obtaining equivalent UK or EU authorizations.
4. Contractual review:Review the target's material contracts for governing law, jurisdiction, and dispute resolution provisions. Post-Brexit, the enforcement of UK judgments in the EU (and vice versa) has become more complex, as the UK is no longer covered by the Brussels Regulation. The Hague Convention on Choice of Court Agreements provides some coverage, but gaps remain.
5. Workforce analysis:Assess the nationality composition of the target's workforce. If the business relies on EU nationals working in the UK (or UK nationals working in the EU), confirm their immigration status and evaluate the ongoing ability to recruit cross-channel talent.

Frequently asked questions

Does the UK-EU Trade and Cooperation Agreement eliminate tariffs on goods?

The TCA provides for tariff-free and quota-free trade in goods between the UK and EU, but this is subject to rules of origin requirements. Goods must demonstrate sufficient UK or EU content to qualify for zero tariffs, supply chains relying heavily on components from third countries may not qualify for preferential treatment. Additionally, the TCA does not eliminate customs procedures: all goods moving between the UK and EU are now subject to customs declarations, border checks, sanitary and phytosanitary inspections for food products, and VAT at the border. These requirements add cost, complexity, and 2-5 days of delay to cross-channel supply chains, according to the Institute for Government’s regulatory divergence tracker.

Can UK nationals still freely work in EU countries after Brexit?

No. UK nationals wishing to work in EU Member States are now subject to each country’s national immigration rules for third-country nationals. There is no EU-wide work permit; each Member State has its own requirements, processing times, and conditions. For acquirers planning to deploy UK-based management to oversee EU operations post-acquisition, immigration planning must begin early in the deal process. The UK Home Office’s points-based system similarly requires EU nationals to obtain Skilled Worker visas for UK employment, including sponsorship by a UK employer, a job offer at an appropriate skill level, and a minimum salary threshold. Processing times typically range from several weeks to months.

How does Brexit affect data transfers between the UK and EU?

The European Commission adopted an adequacy decision for the UK in June 2021, recognizing the UK’s data protection framework as providing adequate protection under GDPR. This allows personal data to flow from the EU to the UK without additional safeguards. However, the adequacy decision includes a sunset clause requiring periodic review and can be revoked if UK data protection standards diverge materially from EU norms. The UK government has signaled interest in reforming its framework, which could trigger revocation. Acquirers should develop contingency plans (Standard Contractual Clauses or Binding Corporate Rules) and ensure that due diligence data rooms comply with both UK GDPR and EU GDPR requirements.
