Senator Warren Calls the Bluff on Fire Trucks — But the Pricing Power Thesis Has a Real Antitrust Risk

I don't think Elizabeth Warren's latest target is just political theater. And I don't think the three companies that control most of America's fire truck market are innocent.

When you look at what's happened in this industry over the last two decades, it is the textbook case of private equity consolidation creating an oligopoly with pricing power — the exact kind of pricing power I look for when building a portfolio. The problem is that the pricing power in this case is attracting bipartisan political heat that could genuinely reshape the industry. And that changes the risk/reward equation for investors who own these stocks.

Here is what is actually happening.

The consolidation is real, and the numbers are stark

Two decades of serial acquisitions by private equity firms — led by American Industrial Partners, which rolled up independent manufacturers into what became REV Group — have reduced an industry that once had dozens of competitors to an oligopoly. Three companies now control approximately 80 percent of U.S. fire apparatus production: REV Group (which owns E-ONE, Ferrara, KME, and Spartan), Oshkosh Corporation (which owns Pierce Manufacturing), and Austria-based Rosenbauer.

The result: pumper trucks have doubled from roughly $500,000 in 2013 to about $1 million today. Ladder trucks have gone from $900,000 to $2 million. Fort Wayne, Indiana's fire chief — a municipal buyer who minimizes optional technology to control costs — told his local paper that a $2.5 million truck request was "about average, below average" for his department's needs. A $10 million budget that once bought 10 to 12 fire trucks now buys five, according to a Philadelphia-area union president.

Delivery times stretched from 18 months pre-pandemic to three or four years in many cases. During the January 2025 California wildfires, over 100 of 183 Los Angeles Fire Department trucks were out of service — because they couldn't get replacements fast enough.

The political response is bipartisan and escalating

This is where the Warren headline matters beyond the politics. The pressure isn't coming from one side. On July 21, 2026, Warren teamed up with Republican Senator Jim Banks of Indiana to file a bipartisan, bicameral resolution directing the Federal Trade Commission to investigate the fire truck market under Section 6(b) of the FTC Act — authority that lets the FTC compel companies to produce documents and conduct wide-ranging studies.

The FTC has already opened an investigation. Los Angeles County filed an antitrust lawsuit alleging the manufacturers created "highly concentrated and oligopolistic markets" and reaped "extraordinary profits" by raising prices and reducing supply. Milwaukee filed a class action alleging price-gouging and coordinated delivery suppression through industry association meetings where competitors exchanged competitively sensitive information. Texas Attorney General Ken Paxton issued civil investigative demands to all three manufacturers. Dozens of municipalities are now consolidating cases in the Eastern District of Wisconsin.

At a September 2025 Senate hearing — the first in at least 30 years focused solely on fire apparatus — Republican Senator Josh Hawley noted that REV Group held a $4 billion order backlog while its profit margins more than doubled, funneling money to dividends and a $6 million CEO paycheck rather than manufacturing capacity. He called the situation "literally killing people" while manufacturers make "ungodly sums of money."

The manufacturers deny wrongdoing. REV Group and Pierce attribute delays to post-pandemic labor shortages and supply chain problems. Pierce VP Dan Meyer told the Senate that the company has been "fair, honest and transparent" and doesn't believe it has "anything to hide." Both have pointed to significant capacity investments since 2022.

The pricing power question

From an investment standpoint, this is where the analysis gets interesting. Fire trucks are mission-critical products. Every city in America needs them. There are no substitutes. The customer cannot simply switch to a cheaper brand or go without. That is the definition of pricing power — the single filter I apply to every candidate before I look at anything else.

If you can raise prices without losing customers, you can grow dividends through inflation. That is the entire thesis for dividend growth investing in a world where I believe inflation is likely to remain more persistent than the market wants to admit.

But here is the risk: pricing power built on anticompetitive consolidation is different from pricing power built on a genuine competitive moat. The former can be undone by regulators. The latter endures.

What the public companies look like

REV Group is no longer a standalone investment. In February 2026, REV merged with Terex Corporation (NYSE: TEX), combining REV's specialty vehicle portfolio — including its fire truck brands — with Terex's construction and aerial equipment. Terex trades at $67.73, with a market cap of $7.7 billion. On the surface, the valuation looks stretched: 52 times trailing earnings, a sub-1% dividend yield (0.79%), and a payout ratio of 48%. Terex has paid dividends for 12 consecutive years but only four consecutive years of dividend growth. The merger with REV adds regulatory overhang to an already richly valued industrial.

Oshkosh Corporation (NYSE: OSK), which owns Pierce Manufacturing, is a different picture. It trades at $155, with a $9.6 billion market cap and a trailing P/E of 17 times — reasonable for an industrial with pricing power. Free cash flow over the trailing twelve months is $1.1 billion, up 99% year-over-year. The dividend yield is 1.4%, with a 23% payout ratio and 11 consecutive years of dividend growth. The balance sheet is clean: $4.5 billion in equity, a current ratio of 172%, and net debt of $700 million.

Oshkosh reported second-quarter 2026 results on July 28, beating consensus on both revenue ($2.9 billion) and earnings ($2.87 per share). That kind of execution, combined with the financial profile, is the equity yield curve sweet spot I look for: a moderate yield with strong growth potential, backed by a balance sheet that can sustain the payout.

The counterargument is real

The strongest case against owning these stocks right now is the antitrust risk. This isn't a theoretical threat. Lawsuits are filed, investigations are open, and the political pressure is bipartisan. If the FTC or courts find that these manufacturers engaged in anticompetitive conduct — coordinated pricing, supply suppression, exclusionary arrangements — the remedies could include divestitures, conduct restrictions, or back-dated damages. That would fundamentally alter the pricing power thesis.

Oshkosh has a slightly cleaner record than REV did. The company acquired Pierce in 1996 but claims its subsequent growth has been organic rather than through roll-ups. Still, as one of the three dominant players in an 80%-consolidated market, Oshkosh benefits from the same oligopolistic structure that lawsuits allege is unlawful.

Manufacturers also have a legitimate defense on the cost side. NFPA standards (National Fire Protection Association) have evolved. Emissions regulations have tightened. Custom-built vehicles for specialized municipal needs are inherently expensive to produce. Labor costs in skilled manufacturing have risen. These are real cost drivers, and they matter — they just don't explain why prices have doubled while margins have expanded from low single digits to low double digits, with some companies targeting 15% margins going forward.

Where the opportunity sits

I believe the fire truck oligopoly has real pricing power — the kind that produces compounding dividend growth through inflation — but that pricing power carries regulatory risk that an investor has to price in. Not every investor will be comfortable with that trade-off.

Oshkosh, with its stronger balance sheet, reasonable valuation, growing dividend, and slightly less aggressive acquisition history, is the one in this cluster that passes my full filter: pricing power, balance-sheet strength, payout durability, and a valuation that doesn't require you to pray. The antitrust risk is real, but the stock isn't priced as if it faces an existential threat. At 17 times earnings with 11 years of dividend growth and a 23% payout ratio, the market is pricing in execution, not collapse.

Terex is harder to justify. The merger with REV doubles its exposure to the fire apparatus controversy while the stock already trades at a premium valuation and offers a sub-1% yield. From an income and risk/reward point of view, I don't think the math works unless you're betting on post-merger cost synergies that have a long track of not delivering.

The broader lesson is not about fire trucks specifically. It is about how to evaluate pricing power. If the pricing power comes from being the only game in town because you eliminated the competition, regulators will eventually notice. If it comes from a product the economy literally cannot function without — energy, defense, logistics, emergency infrastructure — you still need to be comfortable that the structure supporting that pricing power can survive scrutiny. Mission-critical businesses with pricing power are the backbone of a concentrated dividend growth portfolio. But the structure of that pricing power matters.

I don't need the antitrust cases to be dismissed for Oshkosh to make sense. I just need the core oligopoly structure — three players, mission-critical product, no viable substitutes — to endure long enough for the dividend compounder to do its work. And that is a probability-weighted bet, not a guarantee.

This may not fit every investor, especially retirees who need certainty. But from a risk/reward standpoint, the equity yield curve approach still applies: buy pricing power when the market is focused on regulatory headlines rather than cash flow durability, and let compounding do the heavy lifting.
