M&A Regulatory Overview

Navigating the complex regulatory landscape is one of the most critical aspects of M&A transactions. Failure to properly address regulatory requirements can delay or even derail deals, resulting in significant costs and lost opportunities.

Why Regulatory Compliance Matters

Core Regulatory Frameworks

1. Antitrust & Competition Law

Purpose: Prevent anti-competitive mergers that would harm consumers through reduced competition, higher prices, or limited innovation.

Key Jurisdictions:

• United States: Hart-Scott-Rodino (HSR) Act, DOJ/FTC review
• European Union: EU Merger Regulation (EUMR)
• United Kingdom: Competition and Markets Authority (CMA)
• China: State Administration for Market Regulation (SAMR)

2. Industry-Specific Regulations

Certain industries face additional regulatory oversight:

3. Securities Regulations

Applies to: Public companies, private companies with registered securities

Key Requirements:

• SEC filings (8-K, proxy statements, tender offer documents)
• Shareholder disclosure and voting requirements
• Insider trading restrictions and blackout periods
• Financial reporting and audit requirements

4. Foreign Investment Review

Many countries have established committees to review foreign investments for national security implications:

Country	Agency	Key Sectors Reviewed
United States	CFIUS	Defense, critical infrastructure, technology, data
United Kingdom	ISU (Investment Security Unit)	Military, dual-use, critical infrastructure
European Union	FDI Screening Regulation	Critical technologies, infrastructure, sensitive information
Australia	FIRB	Agriculture, critical infrastructure, media
Canada	Investment Canada Act	Cultural industries, national security

Multi-Jurisdictional Filings

When Multiple Filings Required

A transaction typically requires multiple jurisdictions when:

1. Combined entity meets local revenue thresholds
2. Target has significant local operations
3. Deal involves regulated industries (banking, telecom, etc.)
4. National security concerns exist

Major Filing Jurisdictions

Regulatory Review Standards

Antitrust Analysis Framework

Regulators assess deals using several key factors:

1. Market Definition

• Relevant product market
• Geographic market scope
• Temporal dimension

2. Market Concentration

• HHI (Herfindahl-Hirschman Index): Measure of market concentration
• Post-merger HHI levels and delta
• Market share analysis

3. Competitive Effects

• Horizontal overlap analysis
• Vertical integration concerns
• Unilateral vs. coordinated effects
• Entry barriers and potential competition

4. Efficiencies

• Cost savings and synergies
• Consumer benefits
• Innovation enhancement
• Verifiable and merger-specific efficiencies

5. Failing Firm Defense

• Financial condition of target
• Likelihood of exit from market
• Alternative less anti-competitive purchasers

Common Regulatory Remedies

When competition concerns arise, regulators may require remedies:

Structural Remedies

Divestitures:

• Sale of overlapping business units
• Divestment of facilities or assets
• Carve-out of specific product lines

Behavioral Remedies

Conduct Requirements:

• Non-discrimination provisions
• Access commitments for competitors
• Licensing of intellectual property
• Firewall arrangements
• Ring-fencing of sensitive information

Prohibition

In rare cases, regulators may block deals entirely:

Recent Notable Blocks:

• Nvidia-ARM ($40B, 2022) - Competition concerns from multiple jurisdictions
• Aon-Willis Towers Watson ($30B, 2021) - DOJ antitrust challenge
• Broadcom-Qualcomm ($117B, 2018) - CFIUS national security concerns

Best Practices for Regulatory Success

1. Early Engagement

• Pre-notification discussions with key regulators
• Understand regulatory concerns before signing
• Build relationships with regulatory staff
• Engage experienced antitrust counsel early

2. Thorough Preparation

• Comprehensive competitive analysis
• Market studies and customer interviews
• Economic analysis and modeling
• Identify potential remedies in advance

3. Proactive Communication

• Regular updates to regulators
• Transparent disclosure of issues
• Responsive to information requests
• Address concerns head-on

4. Deal Structure Considerations

• Include reverse break fees for regulatory risk
• Appropriate outside date to allow for review
• Clear allocation of regulatory risk
• Covenant packages that balance risk

5. Remedy Planning

• Identify divestiture candidates early
• Prepare "fix-it-first" packages if needed
• Line up potential buyers for divestitures
• Consider hold separate requirements

Regulatory Risk Assessment

High-Risk Deals

Transactions likely to face intense scrutiny:

• High market concentration (combined share >40%)
• Head-to-head competitors in concentrated markets
• Vertical integration reducing access to key inputs
• Platform markets with network effects
• Technology/data intensive businesses
• Politically sensitive sectors (pharma, defense, media)

Medium-Risk Deals

Deals requiring careful analysis but likely approvable:

• Moderate market overlap (combined share 20-40%)
• Adjacent market expansion
• Portfolio acquisitions with limited overlap
• International deals with multiple jurisdictions

Lower-Risk Deals

Transactions unlikely to face significant issues:

• Small market share (<20% combined)
• Conglomerate mergers with no overlap
• Geographic market expansion (no overlap)
• Small acquisitions below filing thresholds

Cost of Regulatory Review

Direct Costs

Cost Category	Range
Legal fees (US antitrust)	$500K - $5M+
Legal fees (multi-jurisdictional)	$2M - $20M+
Economic consultants	$200K - $3M+
Filing fees (global)	$50K - $500K
Document production & review	$100K - $2M+

Indirect Costs

• Executive time and distraction
• Delayed synergy realization
• Market uncertainty and stock volatility
• Competitive disadvantages during review
• Risk of deal break (reverse termination fees)
