Defending Hsr Merger Filing Enforcement Actions in Manhattan

A transaction triggers HSR filing duties based on specific statutory criteria, including the Size-of-Transaction and Size-of-Person tests. These monetary thresholds adjust annually based on changes in the gross national product. For 2026, the minimum Size-of-Transaction threshold is $133.9 million, effective February 17, 2026.

Understanding HSR filing requirements helps corporate buyers and sellers structure acquisition agreements while accounting for regulatory timelines:

Retaining experienced legal representation proficient in regulatory compliance ensures that transactional documents and premerger filings fulfill federal antitrust requirements.

Preparing an HSR notification requires gathering transactional agreements, financial statements, and responsive transaction-related documents. Legal teams carefully review internal strategy reports, pitch decks, and synergy evaluations to ensure full compliance with the applicable federal disclosure requirements.

Upon filing the HSR Form and paying the required filing fee, the statutory waiting period begins:

• Initial 30-Day Review: The FTC and DOJ review submitted materials to determine whether the deal warrants further antitrust scrutiny.
• Early Termination Considerations: Although statutory waiting periods apply, regulatory agencies evaluate competitive effects during the initial review phase, and early termination may be available when authorized.
• Second Request Issuance: If regulators identify potential competitive concerns, an agency may issue a formal request for additional information, extending the waiting period until the parties substantially comply and the applicable additional waiting period expires.

When merger transactions involve complex corporate structures or asset transfers, consulting specialists in corporate governance maintains compliance throughout internal document reviews.

• Analyze Competitive Overlap: Assess product markets and geographic overlap using economic modeling to address agency concerns early.
• Coordinate Document Discovery: Manage extensive e-discovery requests to meet Second Request compliance requirements efficiently.
• Negotiate Regulatory Remedies: Evaluate potential divestitures or other commitments to resolve agency competition concerns.
• Prevent Premature Operational Integration: Maintain appropriate operational separation between merging entities to avoid gun-jumping violations.

Companies facing parallel white-collar or regulatory exposure engage attorneys skilled in white collar crime to manage multi-agency investigations effectively.

Multinational transactions require careful coordination of filing schedules to prevent inconsistent factual disclosures across jurisdictions. Coordinating submission timelines ensures that foreign competition clearances align with federal HSR waiting periods.

Global corporate combinations account for varying notification thresholds and review periods across foreign competition agencies. Working alongside experts in international dispute resolution ensures that global transaction structures comply with both federal and foreign merger control rules.

Unlawful gun-jumping can occur when parties prematurely exercise operational control over a target business or otherwise consummate a reportable transaction before the applicable HSR waiting period expires. Prohibited conduct may include premature operational integration or other actions that transfer control or violate applicable antitrust requirements. Competitively sensitive information sharing should also be managed carefully through appropriate safeguards.

HSR filing fees depend on the overall value of the transaction according to statutory fee tiers. For 2026, applicable fees range from $35,000 to $2.46 million depending on transaction value. The acquiring person is responsible for payment when filing, although parties may negotiate fee-allocation terms within the definitive acquisition agreement.
