What is Oshkosh's market position?
It is the leading or co-leading producer in each of its categories: JLG in access equipment, Pierce in fire apparatus, McNeilus in refuse trucks, and the primary US supplier of light tactical military vehicles.

Does Oshkosh make the USPS mail truck?
Yes. It won the Next Generation Delivery Vehicle contract in 2021 to replace the aging mail truck fleet, a multibillion-dollar, decade-long program.

The company began in 1917 in Oshkosh, Wisconsin, as Wisconsin Duplex Auto Company, building four-wheel-drive trucks for demanding terrain. It became Oshkosh Motor Truck Manufacturing Company and developed a reputation for severe-duty vehicles: fire apparatus, snow plows, concrete mixers, and military trucks.

Defense work defined the company through most of the 20th century. Its trucks served in every US conflict from WWII forward, culminating in the M-ATV and later the JLTV, which in 2015 won the contract to replace the Humvee. That program anchor a multi-decade defense franchise.

The transformation into a diversified vehicle group came through acquisition. Pierce Manufacturing, the fire apparatus leader, joined in 1996. McNeilus refuse and mixer trucks came in 1998. The 2006 acquisition of JLG Industries for approximately $3.2 billion added the access equipment segment that now generates the most revenue. Oshkosh Truck Corporation became Oshkosh Corporation in 2008.

A landmark 2021 win added a new line: the USPS Next Generation Delivery Vehicle contract, worth billions over a decade, to replace the aging Grumman LLV mail truck fleet.

FY2025 produced $10.42 billion in net sales and $647 million in net income. Q3 2026 sales rose 5.7% to $2.84 billion on JLG strength, though the company lowered its full-year outlook on delays transforming Pierce fire truck production.

As a vehicle manufacturer, the company's sustainability work centers on electrification and operational efficiency. Its NGDV mail truck is offered in electric variants as part of the USPS electrification push, and JLG produces electric access equipment lines.

The company publishes sustainability reporting covering emissions, safety, and manufacturing footprint. Defense work places it outside consumer-facing certifications; its ESG profile is managed through industrial norms and defense contractor compliance.
