Regulatory Framework and Compliance Risk
Global M&A Volume: The Scale That Demands AI
LSEG (London Stock Exchange Group, formerly Refinitiv) reported that global M&A volume totaled approximately $3.2 trillion in 2023. The top 10 M&A law firms collectively advised on more than $1 trillion in transactions in 2023. Deal teams working on billion-dollar transactions face compressed timelines — PE sponsors increasingly demand 60-day close processes that would have been considered impossible a decade ago. AI-powered due diligence, contract negotiation support, and regulatory filing management are now competitive requirements for law firms seeking to serve the most active M&A clients.
HSR Premerger Notification: The Filing That Controls Deal Timing
The Hart-Scott-Rodino Antitrust Improvements Act requires pre-merger notification for qualifying transactions — triggering a 30-day initial waiting period during which the DOJ and FTC review the transaction for antitrust concerns. HSR filing must be made simultaneously by both the acquirer and target, and both filers must provide substantial information about their business operations. A Second Request — which extends the waiting period substantially — requires production of thousands of documents on a compressed timeline that defines whether a deal closes on schedule or months late.
EU Merger Regulation: The Brussels Effect on Global Transactions
Regulation (EC) No 139/2004 (the EU Merger Regulation) requires premerger notification to the European Commission for transactions meeting EU-wide turnover thresholds. Phase I review takes up to 25 working days; Phase II investigation up to 90 additional working days. In major deals, EU merger review — often concurrent with HSR review and filings in a dozen other jurisdictions — drives overall transaction timing. In the Microsoft/Activision transaction, the EU investigation that initially blocked the deal required extensive remedies negotiation before European Commission clearance.
