When evaluating the top line, Caterpillar currently demonstrates a much stronger and consistently larger revenue base compared to Oshkosh.
Caterpillar had generally grown its top line quarter over quarter through late 2025 before a recent sequential dip, while Oshkosh's top line has remained relatively flat.

When you’re looking at the financial health of a company, revenue can tell you a lot. Is it growing, stagnant, or declining? How does it match up against industry benchmarks? And what can it tell investors about the market the company operates in?
The chart above tells two different revenue stories. Caterpillar’s overall revenue base is much larger than Oshkosh’s, topping $19 billion last year while Oshkosh hovers just under $3 billion. Caterpillar has also demonstrated revenue growth, notwithstanding a recent pullback in the first quarter of 2026, despite its much larger total revenue pool, while Oshkosh’s revenue has remained stagnant.
The revenue differences primarily come down to what the two companies do and how they make their money. Caterpillar, one of the largest industrials companies by market cap, is a global manufacturer of mining and construction machinery. That gives it a huge market, but also means it’s a cyclical stock that is dependent on global infrastructure spending and demand, commodity prices, and supply chain disruptions.
Much smaller Oshkosh is more specialized, focusing on defense, fire, and purpose-built vehicles (like the delivery fleet for the U.S. Postal Service). Its reliance on government contracts, which tend to be steady and long-term, helps contextualize the revenue picture above. It may seem like a steadier gig, but it’s also limited by government budgets and highly reliant on maintaining or expanding its institutional relationships. And with a smaller overall revenue base, plus a tighter net margin, Oshkosh may have less room for error.
