What the company does

How it makes money

Allison generates revenue through three primary channels: original equipment manufacturer (OEM) sales to truck and bus builders; aftermarket sales of parts and service; and complete powertrain systems for military and specialty vehicles. The company’s business model relies on long-term supply relationships with major commercial vehicle manufacturers, as well as recurring revenue from replacement parts and service. Defense contracts represent a meaningful segment of revenue, supported by qualification as a supplier to the U.S. Department of Defense.
