Cross-Border M&A Attorney: Regulatory Review and Deal Strategy

A stock purchase, asset purchase, merger, or joint venture can produce different liability, tax, transfer, and regulatory consequences. Deal Structuring should account for those differences before the parties commit to a transaction form.

Preliminary review should identify the ownership structure, regulated assets, material licenses, and jurisdictions connected to the transaction. When a foreign person may acquire interests in a U.S. .usiness, the parties should consider whether CFIUS jurisdiction or a mandatory filing requirement could apply.

Exclusivity provisions can restrict a target from pursuing competing transactions during an agreed period. The drafting should define the duration, prohibited conduct, termination events, and any agreed consequences if the proposed transaction does not proceed.

The parties can use the LOI stage to identify potential filing obligations before finalizing the acquisition agreement. Early analysis is particularly relevant when CFIUS, antitrust review, or sector-specific approvals may affect the expected closing date.

Cross-border diligence may require review of foreign licenses, permits, regulatory history, labor obligations, environmental requirements, and industry-specific restrictions. Local-law analysis may also be necessary when subsidiaries, assets, employees, or required consents are located in another jurisdiction.

The transaction structure can affect tax treatment, withholding obligations, and the allocation of liabilities between the parties. Cross-border tax analysis may also require consideration of applicable treaties and tax consequences arising in more than one jurisdiction.

Representations and warranties can allocate risks identified during diligence, while indemnification provisions can establish procedures for specified post-closing claims. When an earnout is used, the agreement should define performance metrics, accounting principles, measurement periods, and operating rules affecting contingent consideration.

International agreements should distinguish governing law from jurisdiction, venue, and dispute-resolution procedures. General Obligations Law § 5-1401 permits parties to qualifying contracts involving at least $250,000 to agree that the state's law will govern their rights and duties, even without another reasonable connection to the state. Statutory requirements and exceptions still apply.

When CFIUS review may affect an acquisition, the transaction documents should address filing responsibility, regulatory cooperation, closing conditions, and any agreed response to mitigation requirements. The parties should determine separately whether the transaction is subject to CFIUS jurisdiction and whether a filing is mandatory or voluntary. A CFIUS Compliance analysis can address those filing questions without turning the acquisition agreement itself into the primary source of CFIUS compliance obligations.

When the parties submit a formal CFIUS notice, the statutory review period can run for up to 45 days, followed by an investigation of up to another 45 days when required. An additional 15-day investigation extension is available in extraordinary circumstances. Acquisition agreements should account for these periods, filing preparation, government requests, potential mitigation, outside dates, and other regulatory approvals affecting closing.

Federal antitrust rules can apply even when a party to an acquisition is organized outside the United States. For transactions closing on or after February 17, 2026, the minimum HSR size-of-transaction threshold is $133.9 million, although other statutory requirements and exemptions still determine reportability. Other jurisdictions may impose separate notification thresholds and waiting periods, so Merger Clearance planning should account for those regimes when setting regulatory covenants, outside dates, and closing conditions.
