Understanding the Rise of State-Level Pre-Merger Notification Laws

Historically, transactional dealmakers in the United States looked exclusively to the federal government—specifically the Federal Trade Commission (FTC) and the Antitrust Division of the Department of Justice (DOJ)—to determine whether a transaction required pre-merger notification under the Hart-Scott-Rodino (HSR) Act.

However, a paradigm shift is underway. Frustrated by high federal HSR thresholds (which adjust annually and currently hover around $120 million) and perceived gaps in oversight, a growing number of states have enacted their own pre-merger notification statutes. These laws target much smaller transactions, particularly within the healthcare, technology, and retail sectors.

Key Jurisdictions and Their Divergent Frameworks

California OHCA Notice

California's Office of Health Care Affordability (OHCA) requires a mandatory 90-day prior notice for transactions involving healthcare entities where at least one party has annual California revenue or assets exceeding $25 million. Unlike HSR, there is no automatic size-of-transaction exclusion below $119 million.

Washington State Healthcare Transaction Notification Act

Under RCW 19.390, Washington requires healthcare entities to notify the state Attorney General 60 days prior to closing if both parties have $10 million or more in revenue, expanding regulatory focus to mid-market and local medical practice purchases.

Minnesota & Illinois Mandates

Minnesota and Illinois have both enacted legislation requiring 30 to 60 days advance notification for transactions involving hospital systems, provider groups, and allied healthcare services. Crucially, the monetary thresholds are exceptionally low, hovering near $10 million in transaction value or target assets.

Practical Tips for Deal Counsel

  • Identify Nexus Early: Establish the corporate nexus of both parties at the LOI stage. Look closely at employee footprints, regional licensing, and local physical facilities.
  • Align Transaction Timelines: A 90-day state review (like California's) represents a far more significant gating item than a standard 30-day federal HSR review window. Transaction agreements must account for these extended notice periods in the "Outside Date" provisions.
  • Monitor Ongoing Reforms: Tech-focused antitrust review models (e.g., proposed bills in New York) could soon expand pre-merger compliance to the SaaS, AI, and digital marketplace sectors, introducing low-threshold state filings for intellectual property transfers.
