A fire engine is late to the kind of meeting no one wants delayed. A boom lift places a worker six stories above a slab. A military truck crosses ground designed to stop it. A refuse vehicle spends the morning repeating a task a thousand times beside moving traffic. Oshkosh Corporation builds for these blunt realities - work where the machine is not scenery but a colleague, shield and livelihood.
The name suggests one category: trucks. The actual company is harder to hold in a single image. Its JLG machines raise people and material. Pierce builds fire apparatus. McNeilus works the curb. Oshkosh AeroTech moves bags, bridges and aircraft-support gear around airports. Oshkosh Defense supplies tactical vehicles. Jerr-Dan handles the awkward aftermath of the road. And the company's Transport segment is ramping production of the U.S. Postal Service's Next Generation Delivery Vehicle, the high-roofed van likely to become its most familiar machine.
What unites that catalog is not a body style. It is consequence. These customers measure products in response time, utilization, safety, payload, route completion and cost over years. Novelty is welcome only after it survives rain, salt, dust, heat, hurried operators and municipal budgets.
A company large enough to need a comma in its patent count, yet still headquartered on Four Wheel Drive.
01 / The originWhen nobody bought the invention, they built the company
The Oshkosh story starts with a useful rejection. William Besserdich and Bernhard Mosling had developed front-driving and automatic locking differential technology in Wisconsin. They could not find a buyer. In 1917, they formed Wisconsin Duplex Auto Company and produced a prototype nicknamed Old Betsy. The company moved to Oshkosh, adopted the city's name and spent the next century finding difficult terrain.
There is a neat corporate joke hidden in plain sight: headquarters sits at 1917 Four Wheel Drive. The address reads like a tiny autobiography. The company that began by making bad roads negotiable later built snowplows, airport-rescue vehicles, military fleets and a portfolio of specialty-equipment brands.
Its history also explains the present. Oshkosh did not begin with a broad theory about mobility. It began with a stubborn technical solution and a customer problem. In 2010, it sent a hybrid predecessor of the Joint Light Tactical Vehicle through the 1,061-mile Baja 1000. The prototype finished a race that nearly 40 percent of entrants did not. Extreme use was not a marketing metaphor. It was the test plan.

02 / The portfolioThree businesses, one engineering exchange
Oshkosh reports three segments. Access accounted for 43 percent of 2025 sales, led by JLG and SkyTrak aerial platforms and telehandlers. Vocational contributed 36 percent through fire apparatus, refuse trucks, airport products, concrete mixers, field-service trucks and command vehicles. Transport supplied 20 percent, chiefly defense vehicles and postal delivery. A small corporate-and-other category fills out the total.
2025 sales mix - a portfolio balanced across different work cycles
The spread is strategic. Construction rental demand, municipal purchasing and federal programs do not move in perfect formation. That diversity can soften a weak market, though it cannot eliminate cycles, contract risk or factory problems. In 2025, the company recorded $10.422 billion in sales. About 20 percent came from the U.S. government, mostly through multi-year programs. The largest single segment was Access, not Defense.
The more interesting benefit is technical. Oshkosh describes autonomy, artificial intelligence, connectivity and electrification as shared pillars. Its patented TAK-4 independent suspension appears across defense, Pierce fire and airport-rescue vehicles. A modular autonomous platform developed for military work can be repurposed to assist crews on an airport ramp. Sensors and perception systems can protect people beside a roadway or help a refuse vehicle identify contamination as bins are collected.

03 / The customerSelling outcomes that arrive wrapped in steel
Oshkosh's customers are organizations, not hobbyists. Equipment-rental companies need machines working and earning. Contractors want workers and material placed safely at height. Fire departments need apparatus configured for local tactics. Waste companies need more productive routes. Airports and airlines need turns completed without a ground-support bottleneck. Defense agencies need mobility, protection, parts and sustainment. The Postal Service needs a delivery vehicle suited to repeated curbside stops, package volume and a long service life.
That makes the business model broader than manufacturing. Oshkosh sells equipment through direct channels, dealers and distributors. It competes for government and municipal programs. Then it supports machines through parts, service, refurbishment, technology and sustainment. The steel creates the installed base; lifecycle support keeps the relationship alive.
Its alternatives change by aisle. Terex and Manitou compete in access. REV Group and Rosenbauer appear around fire apparatus. Federal Signal and Heil contest refuse fleets. Textron, General Dynamics and BAE Systems inhabit defense markets. Airport equipment has its own specialists. Oshkosh's distinction is the connective tissue: a large, purpose-built portfolio that can amortize learning across different jobs while retaining brands that customers already know.
04 / The new machineSoftware meets mud, curbs and jet bridges
At CES 2026, Oshkosh showed what that connective tissue looks like when it moves. A JLG boom lift fitted with a robotic end effector could handle repetitive work such as painting, welding or material placement without putting an operator at height. Micro scissor lifts demonstrated leader-follower movement. An AI system looked for recycling contamination at collection. Autonomous modular robots tackled repeatable airport-ramp jobs. The Striker Volterra electric aircraft-rescue truck paired battery power with emergency acceleration.
Two of those products - the robotic JLG boom lift and Striker Volterra - received 2026 CES Best of Innovation awards. Another system, the Collision Avoidance Mitigation System, won a CES Picks award for anticipating roadside hazards near first responders and other workers. Awards do not prove adoption, but they reveal where Oshkosh is placing its R&D: not generic software, but software pressed against a particular task.
The same discipline applies to electrification. A battery is not automatically useful because it is fashionable. A refuse truck's route is repetitive and returns to base, which can make charging predictable. An electric access platform removes local emissions and cuts noise indoors. Airport support gear operates in contained environments. A delivery van follows a known route. Purpose determines whether the powertrain makes economic and operational sense.

05 / The balance sheetA mature manufacturer with an acquisition habit
Oshkosh is publicly traded on the New York Stock Exchange under OSK, so its funding story is not a parade of venture rounds. It finances product development through operating cash flow and capital markets, returns capital through dividends and repurchases, and uses acquisitions to add markets or capability. The company spent about $805 million for JBT's AeroTech business in 2023, adding airport ground support and services. It bought Italian tracked-equipment maker Hinowa for roughly $187 million that year and Spanish compact-equipment maker AUSA for $114.5 million in 2024.
Those purchases broaden geography and recurring revenue, but they also raise the standard for integration. The portfolio only earns its story if brands share technology without losing customer focus. A dozen logos do not create a platform by themselves.
Recent numbers show both momentum and friction. Second-quarter 2026 sales rose 6.7 percent from a year earlier to $2.915 billion, helped by Access volume and the delivery-vehicle ramp. Net income fell to $183.2 million as sales mix and manufacturing overhead weighed on results. Transport revenue increased 11.9 percent, but its operating margin was 2.9 percent. The NGDV program is becoming more visible in the factory before it becomes commonplace on the street.
06 / The marketThe overlooked infrastructure of ordinary life
Oshkosh sits where capital goods, mobility and industrial software overlap. It is exposed to construction cycles, public budgets, defense priorities, supply chains and the slow replacement cadence of expensive equipment. That makes it less nimble than a software firm and more difficult to copy. Customers are not buying an app and trying it on Tuesday. They are buying a machine, training people around it, stocking parts and planning years of use.
The company's stated culture - people first, do the right thing, persevere, better together - is designed for that long horizon. Its 2025 sustainability report lists $173.7 million in global R&D spending, 84.2 percent of waste diverted from landfill and $3.1 million in community investment. Ethisphere named it one of the World's Most Ethical Companies for an eleventh consecutive year in 2026. Those measures are company-reported or award-based, not substitutes for scrutiny, but they describe the institution Oshkosh wants to be.
The best way to understand the company is to notice the work it makes less noticeable. A jet bridge meets the plane. A lift reaches the duct. A refuse route finishes. A fire crew gets room to operate. A package van returns to the depot. The machines are loud; the outcome is quiet. Ordinary life continues without asking who built the equipment underneath it.
