Practitioner Application: M&A Regulatory Approvals: HSR, CFIUS, and Shareholder Actions
Your client, a large U.S. technology company, has just signed a definitive agreement to acquire a smaller, innovative competitor with significant market share in a niche segment. Simultaneously, a different client, a U.S. aerospace defense contractor, is being acquired by a foreign state-owned entity. Both deals are contingent on regulatory approval. You need to explain the distinct regulatory reviews each transaction will face, including mandatory filings, typical timelines, and the specific concerns of agencies like the Department of Justice, the FTC, and CFIUS, as well as potential shareholder approval requirements.
- After a 'definitive agreement' is signed, M&A transactions often require various regulatory approvals and shareholder actions before they can close. These are critical steps designed to protect competition, national security, and shareholder interests.
- Purpose: The 'HSR Act' requires parties to certain mergers, acquisitions, and tender offers to file premerger notifications with the Federal Trade Commission (FTC) and the Department of Justice (DOJ) and observe a waiting period before closing the transaction. This allows the antitrust agencies to review the proposed transaction for potential anti-competitive effects.
Common FINRA Series 79 Distractors on FINRA · S79-F3
- 1⚠️ Exam trap: Confusing the purpose of 'HSR' and 'CFIUS'. 'HSR' is exclusively about antitrust and competition, while 'CFIUS' is solely focused on national security implications of foreign investment. Do not conflate these two distinct regulatory concerns.
- 2⚠️ Exam trap: Incorrect 'HSR' waiting periods. Remember the 15-day period specifically for 'all-cash tender offers' versus the 30-day period for most other types of 'HSR'-reportable transactions. This is a common point of confusion.
- 3⚠️ Exam trap: Assuming all deals require all approvals. Not every deal will trigger every regulatory review. For example, a purely domestic merger below 'HSR' thresholds might not require 'HSR' review, and a domestic-only deal will not involve 'CFIUS'.
- 4HSR Act: Requires premerger notification to 'FTC' and 'DOJ' for certain transactions to review antitrust implications. Initial waiting period is 30 days, or '15 days for all-cash tender offers'.
- 5CFIUS: Reviews foreign investments in U.S. businesses for 'national security' risks. Filings can be voluntary or mandatory for certain sectors.
