Editor’s Introduction: Global M&A

Global M&A has entered a more disciplined and structurally complex phase. The volatility of recent years — pandemic disruption, monetary tightening, geopolitical fragmentation and regulatory activism — has not diminished the strategic importance of M&A transactions. Instead, it has recalibrated how capital is deployed, how risk is allocated and how control is exercised. In 2026, dealmaking is defined less by exuberance than by selectivity, and less by speed alone than by certainty of execution.

After a subdued 2023 and a tentative recovery in 2024, 2025 marked a renewed assertion of strategic dealmaking. Worldwide M&A rebounded significantly, totalling approximately USD 3.7 trillion through the first 11 months of 2025, a 31% increase over the same period in 2024. Yet this resurgence was concentrated rather than universal — driven disproportionately by large-cap and public-to-private transactions. While aggregate value rose sharply, global deal volume declined by roughly 5% year-on-year, suggesting that capital focused on larger, transformative transactions rather than broad-based mid-market expansions. The message is clear: capital has not retreated from M&A; it has become more deliberate, more concentrated and more strategically deployed.

Boards and investors are increasingly pursuing transactions that deliver scale, technological capability, supply chain resilience or portfolio repositioning. Incremental acquisitions still occur, but the market increasingly rewards combinations capable of altering a company’s competitive trajectory or accelerating its long-term strategy. Financing opportunities, while more disciplined than in prior cycles, remain available for well-structured and strategically compelling deals. Where valuation gaps persist, they are bridged through structured consideration, staged ownership and refined risk allocation mechanisms. The current global M&A environment is therefore less about expansion at any cost and more about strategic clarity and execution discipline.

A defining feature of this cycle is the systemic scale of private capital, which has become embedded in the architecture of modern dealmaking. Private equity sponsors, sovereign wealth funds, private credit platforms and large family offices now operate as structural pillars of the global M&A market. Sponsor-backed transactions account for a significant share of global deal value, with public-to-private activity remaining particularly prominent. The influence of private capital extends beyond transaction value — sponsors have reshaped transaction technique and expectation. Structured auction processes, vendor due diligence, representations and warranties insurance, tightly calibrated interim operating covenants and an emphasis on clean exits are now common practice — even in transactions where no sponsor is involved.

Parallel to the rise of private capital is the reassertion of the state as a strategic actor in M&A. Governments across major economies have expanded foreign investment screening regimes and adopted more active industrial policies in sectors considered critical to national resilience: defence, semiconductors, energy transition infrastructure, digital networks and advanced manufacturing. National security analysis increasingly extends beyond traditional military assets to encompass data governance, artificial intelligence, supply chain security and technological sovereignty. In certain circumstances, state involvement has moved beyond regulatory oversight to direct participation, including equity stakes, governance rights or structural conditions attached to transaction approval. Transaction structuring must anticipate not only whether clearance will be granted, but under what conditions and with what constraints.

Geopolitics has therefore shifted from background consideration to the forefront of transaction planning. Trade realignments, sanctions regimes and export controls directly affect valuation and conditionality in M&A transactions. Tariff exposure and supply chain concentration have become central diligence themes in recent years. Material adverse effect clauses and earn-out mechanisms increasingly reflect geopolitical contingencies rather than purely operational metrics. The nationality of capital can influence regulatory trajectory as much as competitive effects. However, geopolitical complexity has not halted cross-border M&A — it has reshaped its architecture. Transactions are often paired with joint ventures, licensing arrangements or minority governance structures designed to balance market access with regulatory compliance. Political risk assessment is now inseparable from transaction analysis.

Technology remains a dominant driver of global M&A value. Transactions in artificial intelligence, digital infrastructure, cybersecurity and semiconductor ecosystems continue to attract intense competition. Generative AI and advanced data capabilities are increasingly treated as strategic necessities rather than optional enhancements. Technological assets also attract layered regulatory scrutiny, including data protection compliance, export control considerations and emerging AI governance frameworks. AI also plays a transformative role within the transaction process itself. Advanced analytics and generative tools accelerate document review, contract drafting and risk identification, although these efficiencies also introduce their own legal considerations. Data provenance, intellectual property ownership and compliance with developing regulatory regimes must be assessed rigorously.

Governance has likewise evolved. Courts and legislatures in key jurisdictions have refined standards governing conflicted transactions, minority protections and fiduciary process. Shareholder activism remains influential, particularly in public transactions, where competitive tactics and interloper bids have re-emerged. Contractual tools — reverse termination fees, specific performance provisions and tailored covenants — are deployed with increasing sophistication to allocate risks between signing and closing.

Despite these common structural forces, M&A law remains inherently jurisdiction-specific. Regulatory thresholds, minority approval mechanisms, disclosure standards and litigation risk vary materially across jurisdictions. While convergence is visible in transaction techniques, divergence persists in public law architecture. This guide offers a structured, jurisdiction-by-jurisdiction analysis of the principal legal frameworks governing mergers and acquisitions across a wide range of markets. As global dealmaking continues to evolve — reflecting both increasing convergence in transaction practice and meaningful divergence in regulatory, political and governance regimes — comparative perspective has become indispensable. We hope that the inaugural edition of this guide will serve as a practical reference for practitioners, in-house counsel and business leaders alike, providing clear insight into the legal environments that shape M&A transactions across an expanding number of active and sophisticated jurisdictions worldwide.
