Key Takeaways
- • Twenty municipalities across multiple states have filed antitrust lawsuits against three private equity–backed fire truck manufacturers (REV Group/American Industrial Partners, Oshkosh Corporation, and Boise Mobile Equipment) that collectively control approximately 70 percent of the U.S. fire truck manufacturing market.
- • The City of Emeryville filed suit on May 21, 2026, alleging defendants engaged in illegal schemes including factory shutdowns, artificial scarcity creation, and dramatic price increases for emergency service equipment, with extended delivery timelines impacting fire department operations nationwide.
- • American Industrial Partners, a private equity firm focused on industrial businesses, initiated market consolidation by acquiring fire truck manufacturers beginning in 2008, establishing the foundation for the current market concentration.
- • Legal representatives seek both monetary damages and injunctive relief—specifically the unwinding of allegedly unlawful mergers—to restore competitive conditions in the fire truck manufacturing sector.
- • Private equity consolidation extends beyond fire truck hardware to critical software systems used by fire departments, creating cascading cost pressures on municipal budgets and volunteer departments unable to absorb price increases that have outpaced inflation.
Summary
On May 21, 2026, the City of Emeryville, a mid-sized municipality near San Francisco, joined at least nineteen other jurisdictions across multiple states in filing federal antitrust litigation against three private equity–backed fire truck manufacturers. The defendants—REV Group and its former parent American Industrial Partners, Oshkosh Corporation and its subsidiaries, and Boise Mobile Equipment and its subsidiaries—collectively control approximately 70 percent of the U.S. fire truck manufacturing industry. The lawsuit, filed in the Northern District of California, alleges the defendants executed coordinated schemes to corner the market, shut down manufacturing plants, artificially constrain supply, and substantially elevate prices for essential emergency response equipment.
According to the complaint, "Through their illegal schemes, Defendants have reaped extraordinary profits on the backs of fire departments, taxpayers, cities, and counties." The litigation specifically cites plant closures, severe price increases, and substantially extended delivery timelines as evidence of anticompetitive conduct. Catherine Simonsen, representing the coalition of municipalities through the Simonsen Sussman law firm and Baron & Budd, emphasized the stakes: "these lawsuits are important because they concern timely and affordable access to lifesaving apparatuses and parts." The municipalities are pursuing not only damages but injunctive relief aimed at unwinding the unlawful mergers to restore market competition.
American Industrial Partners, a private equity firm specializing in industrial assets, initiated the consolidation wave beginning in 2008 by systematically acquiring fire truck manufacturers. This acquisition strategy laid the groundwork for the current market concentration. The consolidated control of fire truck manufacturing has created cascading cost pressures throughout the fire service sector. Beyond hardware, private equity firms have also acquired the software systems deployed across most fire departments, compounding affordability challenges. Fire departments—particularly volunteer and small municipal operations—report that vehicle prices have substantially outpaced general inflation, rendering necessary equipment procurement prohibitively expensive. Delivery delays have extended to years in some cases, leaving departments under-equipped during critical response periods.
The litigation represents a significant institutional challenge to private equity consolidation strategies in essential public services infrastructure. By controlling three-quarters of the fire truck manufacturing market, the defendants allegedly leveraged their position to extract monopolistic pricing from municipalities with inelastic demand for safety equipment. The lawsuits signal growing regulatory and legal scrutiny of private equity roll-up strategies in sectors serving essential government functions, where cost pressures directly impact public safety and taxpayer resources.
