Navigating Cross-Border M&A

Cross-border mergers and acquisitions (M&A) occur when the buyers and target companies involved in the transaction are based in different countries or legal jurisdictions from one another. As the global economy becomes more interconnected, these types of M&As are becoming more important—supporting a more dynamic international business landscape.

These deals require careful navigation of complex legal, regulatory, and cultural frameworks. Success hinges on understanding the nuances of multiple jurisdictions simultaneously, managed by advisors who understand the challenges. As Ascot provides cross-border M&A support worldwide, rather than in limited regions, we’ve developed this article to provide insights that can help buyers and sellers make informed decisions.

Understanding Cross-Border M&A Fundamentals

The scope of international M&A is relatively broad, beyond simply mergers or acquisitions of companies based in different countries. The transactions can be horizontal, in which companies in the same industry are merged or acquired to enhance market share; vertical, where the entities are part of the same supply chain; or conglomerate, where the aim is to diversify operations by performing M&As with companies in unrelated industries.

The motivations behind international expansion through M&A can vary, though they typically revolve around boosting revenue growth, accessing innovations, gaining cost efficiencies, and enhancing brand visibility. Strategically, it can be advantageous, too, as companies may be able to hedge against regional volatility, with geographical diversification supporting long-term resilience.

These cross-border deals are more complex than their domestic counterparts, though. Companies may need to navigate differing regulatory, financial, and cultural elements on the road to closing.

Current Market Landscape and Global Trends

The international M&A landscape is constantly shaped by evolving trends across a variety of regions. Europe and North America have remained central hubs for deals in recent years, largely due to stability and infrastructure. Asia-Pacific is a key focus for targets due to strong economic growth and emerging markets—this last is increasingly impacting global transaction flows with both fresh opportunities and more complex logistical elements.

Certain sectors are also trending cross-border focuses. Technology, pharmaceuticals, and renewable energy are popular as buyers prioritize innovation and alignment with shifting global priorities. Indeed, geopolitical factors such as shifting trade policies and national security concerns are also influencing deal flows. Furthermore, regulations around international M&A are evolving with more robust antitrust frameworks and disclosure requirements, affecting the structure of deals.

Legal and Regulatory Framework Considerations

M&A transactions across borders often navigate a patchwork of international legal systems and jurisdictional differences in regulations. This tends to require insights both from expert internal regulatory teams and external consultants with experience in the nuances of specific regions. This is particularly important when ensuring alignment with complex antitrust and competition laws in various countries, alongside maintaining compliance with varying securities regulations and disclosure requirements. 

Foreign investment approval procedures are a common concern, too, as is the increasing number of national security reviews. Regulatory bodies in the U.S., China, and some E.U. states can delay or even block transactions in the name of public interest.

Additionally, companies must carefully examine the tax implications of foreign acquisitions and strategize leveraging treaties appropriately.

Due Diligence in International Transactions

International due diligence processes are central to pre-acquisition planning and must account for jurisdictional variations in multiple areas. Firstly, diverging accounting standards must be considered during financial due diligence, such as International Financial Reporting Standards (IFRS) and U.S. Generally Accepted Accounting Principles (GAAP).

For regulatory due diligence, companies must assess the target and transaction’s compliance with any applicable domestic laws where both the buyer and seller are located, alongside international obligations like environmental and labor standards.

Examinations of differences in business environments—particularly logistics, supply chains, and vendor connections—will form part of operational due diligence. Additionally, there must be management and workforce assessments to identify potential hurdles in cultural alignment.

It’s also important to understand that how technology and intellectual property (IP) are managed varies between regions, including data privacy laws and asset protections. These elements must be scrutinized to ensure robust safeguarding.

Valuation Challenges in Cross-Border Deals

Various elements can make valuation more challenging across borders. Firstly, currency rate fluctuations can affect final purchase prices, and companies may need to use hedging strategies as insurance against losses. The choice of valuation methodology might also need to be adjusted to reflect differing market norms and cost structures between regions, which often forms part of the investment bank role in M&A​. Furthermore, geopolitical or sovereign risks must be assessed, with the results factored into discount rates where there are particularly volatile markets.

There are also differences in accounting standards depending on the jurisdiction, which can result in mismatched reported and underlying values. Not to mention that the market multiples used for benchmarking target acquisitions may not necessarily align across countries. Both of these elements require normalization adjustments to perform reliable valuation comparisons.

Cultural Integration and Management Considerations

While it is often underestimated in international M&A, cultural and management alignment is both challenging and a key success factor. Buying teams need to perform due diligence to understand the extent of cultural or management differences between organizations. From here, they can develop strategies that proactively address communication hurdles across different languages, alongside bringing diverging operational norms into alignment.

Leadership integration in multinational environments is particularly sensitive, and buyers must carefully consider whether to keep or replace management, as this can impact operations and morale. Indeed, collaboration between talent management professionals across borders can influence employee retention. Furthermore, teams must develop governance structures for international operations that address gaps in oversight and accountability when management shifts occur.

Tax Planning and Optimization Strategies

International tax treaty networks are vital components of cross-border tax planning in M&A, as they provide relief from double taxation. Nevertheless, it’s important that leveraging these treaties is guided by international experts, as they require careful interpretation. Transfer pricing rules also need to be considered, as they govern how profits are distributed between jurisdictions, which, in turn, affects tax liabilities.

Additionally, companies must consider how cross-border tax withholding on dividends, interest, and royalties might erode the value of the M&A transaction and apply strategic mitigation processes accordingly. In some instances, setting up holding companies in tax-efficient countries can help streamline international tax flow. Once the acquisition is complete, companies will also need to develop tax integration plans that align reporting and withholding in ways that meet strategic goals.

Risk Management in International M&A

Even in relatively straightforward situations, cross-border deals can expose companies to various risks that must be managed. Buyers need to carefully assess hazards that could stem from political instability in target jurisdictions alongside sovereign risks, such as unexpected trade policy shifts. There are also risks of currency fluctuations throughout the transaction lifecycle that may need to be mitigated with hedging strategies.

Another key risk concern is regulatory compliance, due to differing standards and frameworks across jurisdictions. Careful due diligence performed by international M&A consultants helps ensure requirements are met, which prevents putting the deal in jeopardy.

Additionally, teams need to assess and mitigate operational risks, particularly those stemming from misaligned supply chains, IT systems, and workforces. Issues here can disrupt productivity and impact the eventual value of the deal.

Finally, contractual risks can present issues not just in the finalization of the deal, but potentially years down the line. Agreements must be carefully drafted by experienced advisors, including clear assignment of liabilities, contingencies for unexpected issues, and—most importantly—that these contracts are enforceable between jurisdictions.
