Should federal regulators more aggressively block mergers that could limit competition in essential markets?
Judge Nina Gershon denied Gerber's motion to dismiss an antitrust lawsuit brought by P&L Development. The litigation centers on Gerber's sale of its Wisconsin manufacturing facility to Perrigo, which the complaint alleges created significant market entry barriers.
Why it matters
This ruling allows claims to proceed that the acquisition served to entrench Perrigo's market power in the infant formula sector. For operators, it underscores the heightened regulatory and legal risk associated with plant divestitures that could be construed as reducing competition.
A federal court denied the motion to dismiss a case involving the sale of a single infant formula manufacturing facility in Wisconsin. The scope of the litigation involves the competitive dynamics of the domestic market following the plant transfer.
The players
Nina Gershon
A United States District Judge for the Eastern District of New York overseeing the antitrust proceedings.
Gerber
A prominent nutrition company and major supplier of infant formula in the United States.
P&L Development
A pharmaceutical and consumer goods entity currently acting as the plaintiff in the antitrust litigation.
Perrigo
A global self-care company and major manufacturer of infant formula that acquired the Wisconsin facility.
The details
The amended complaint filed by P&L Development argues that the sale of the Wisconsin plant effectively solidified Perrigo's market position. By offloading its only U.S. production site, the plaintiffs contend that Gerber inadvertently facilitated a market structure that prevents new entrants from competing effectively. The court's decision to move the case forward means these arguments regarding market entrenchment will now be subject to formal discovery processes.

Market Landscape
This case sits at the heart of intensifying scrutiny regarding the U.S. infant formula supply chain and historical consolidation. It follows a pattern of heightened judicial interest in how manufacturing divestitures shape long-term barriers to market entry.
Supply chain managers and legal teams should evaluate whether planned divestitures could be perceived as reinforcing incumbent market power. Watch for discovery disclosures that might reveal new industry-wide standards for what constitutes an anticompetitive exit.
The takeaway
Antitrust scrutiny in the consumer goods space is increasingly targeting the structural impact of manufacturing sales. Operators should review their M&A and divestiture strategies through the lens of market accessibility to avoid similar litigation traps.
