Allison Transmission Holdings, Inc. (ALSN) Business Profile

What it does

Allison Transmission makes automatic transmissions and other propulsion systems for commercial vehicles, defense vehicles and industrial equipment. A transmission transfers power from an engine or motor to the wheels or other working parts of a machine. Allison’s products are used in vehicles and equipment ranging from school buses, refuse trucks and fire engines to mining trucks and military vehicles.

The company sells primarily to vehicle and equipment manufacturers, which install its products in their own vehicles. It also supplies the U.S. government and serves vehicle owners through a network of independent distributors and dealers. Alongside new equipment, Allison sells replacement parts, transmission fluids and remanufactured transmissions for vehicles already in use.

Allison’s business has two units. Allison Transmission supplies automatic transmissions and electric propulsion products. Allison Off-Highway Drive & Motion Systems supplies products such as axles, gearboxes and motion systems for equipment used in construction, agriculture, mining and material handling. The off-highway business was acquired on January 1, 2026.

Allison was founded in 1915 and is headquartered in Indianapolis, Indiana. David S. Graziosi is its chair, president and chief executive officer.

How it makes money

Allison earns revenue by selling propulsion systems and components to vehicle manufacturers, distributors and the U.S. government. It also earns revenue from service parts, support equipment, defense kits, engineering services, royalties and extended transmission coverage. Customers use its products in on-highway commercial vehicles, off-highway equipment and defense vehicles.

For 2025, North America on-highway sales represented 51% of total sales. In the second quarter of 2026, consolidated net sales were $1.566 billion. The 2025 figures do not include the off-highway business acquired in January 2026.

For North American on-highway vehicles, Allison sells substantially all propulsion solutions to manufacturers. Manufacturers may offer an Allison product as the only propulsion option in a vehicle or install it because an end user requests it. Long-term agreements generally cover commitments concerning product promotion, pricing and the sharing of commodity-cost risk. Allison also sells propulsion systems to manufacturers of tactical wheeled vehicles and supplies tracked-vehicle systems and parts kits to the U.S. Army.

The aftermarket provides revenue after a vehicle enters service. Routine maintenance creates demand for Allison-branded replacement parts and fluids, while remanufactured propulsion systems provide another repair and replacement option. Distributors and dealers are required to sell genuine Allison-branded service parts. Support-equipment sales, by contrast, depend on sales of new solutions because manufacturers use that equipment to install them.

The acquired off-highway unit adds axles, gearboxes, transmissions and motion systems used in both conventional and electrified equipment. Allison’s agreements with some customers provide for recovery of higher material costs; the company says recovery of a substantial portion of commodity increases typically occurs on a 6- to 12-month lag.

Customers and how it sells

Allison serves vehicle and equipment manufacturers, the U.S. government, distributors and end users. Its commercial products go into vehicles used for distribution, refuse collection, construction, emergency services and passenger transport. Defense customers use its products in wheeled and tracked vehicles, while off-highway customers use them in equipment for industries including mining and agriculture.

Daimler AG represented 18.0% of revenue in FY2025, PACCAR Inc. represented 11.0%, and Traton SE represented 10.0%. In the North American on-highway market, OEM customers representing over 90% of Allison’s unit volume participated in long-term agreements in 2025. Those agreements typically run between three and five years.

Approximately 76% of Allison’s revenue came from North America in 2025. The company also serves customers in Asia, Europe, South America and Africa. Outside North America, it sells on-highway products in markets where manual transmissions remain prevalent. Its defense products were in approximately 120 countries as of December 31, 2025.

Allison reaches customers through direct relationships with manufacturers and end users, as well as approximately 1,500 independent distributor and dealer locations worldwide as of December 31, 2025. The network provides sales, service and support for products already in the field. The 2025 geographic revenue mix predates the acquired off-highway business.

Suppliers and costs

Allison purchases many of the parts used in its propulsion systems from outside suppliers. In 2025, it bought approximately $1,022 million of direct materials and components from them. Aluminum and steel castings and forgings are among its largest direct purchases; suppliers form those materials into larger components and assemblies.

For the year ended December 31, 2025, direct materials accounted for approximately 66% of cost of sales, manufacturing overhead for approximately 26%, and direct labor for approximately 8%. Commodity-price changes affect costs. Allison uses long-term agreements to help manage that exposure and says its off-highway business can pass material costs through more promptly than the transmission business historically has.

Allison produces high-volume on-highway products in the United States, India and Hungary. It manufactures defense tracked products and electric hybrid products in Indianapolis, and fully electric propulsion products in Auburn Hills, Michigan. The off-highway acquisition added approximately 46 manufacturing and assembly plants.

As the businesses integrate, Allison is evaluating additional in-house production and plans to qualify multiple sources for critical materials and components. It also expects procurement and logistics initiatives to contribute to its acquisition-related cost-saving target.

Competitive position

Allison competes with manufacturers of manual, automated manual and automatic transmissions, as well as suppliers of hybrid and electric propulsion systems. Some vehicle manufacturers also make transmissions for their own vehicles. Outside North America, manual transmissions remain the predominant type in many commercial-vehicle markets.

In North American on-highway vehicles, Allison names Ford, ZF and Driventic among automatic-transmission competitors. ZF and Driventic also compete with Allison outside North America, alongside Shaanxi Fast Gear. In transit hybrid propulsion, Allison competes primarily with BAE Systems. In off-highway applications, competitors include Caterpillar, Twin Disc, Komatsu, Volvo and ZF. For tracked defense vehicles, Allison names QinetiQ, Renk, SAPA and ST Kinetics.

Allison’s products use specialized engineering and software controls, and its distributor network sells and services products in the field. It also holds patents and relies on know-how and trade secrets; it does not consider its business dependent on any single patent.

Our reading: Engineering and application-specific controls provide a meaningful competitive defense because customers use Allison products across vehicles with different operating requirements. Our reading: Long-term manufacturer relationships and the service network reinforce that position, although manufacturers can make their own transmissions and aftermarket sellers offer alternative parts. Our reading: Intellectual property supports the business, but the company’s own description does not point to a single patent as a decisive barrier.

Growth opportunities

Allison’s growth plans include expanding its off-highway portfolio, winning defense programs and developing propulsion products for changing customer requirements. The January 2026 acquisition added drivetrain and motion products for construction, agriculture, mining, material handling and other industrial applications. Those markets have historically had demand characteristics different from Allison’s traditional on-highway markets.

In the first half of 2026, Allison won off-highway programs in construction and material handling, mining and agriculture. The company says the awards represent more than $50 million of annual run-rate net new business. It also reported year-over-year growth in construction and material handling and mining, while saying agriculture had not yet turned positive.

Defense awards include selection of an Allison transmission for the French Land Forces’ PL6T tactical truck program, supporting more than 7,000 vehicles over the next decade. Allison also secured a $250 million contract to supply its 4040 MX transmission for the CV90 MkIV infantry fighting vehicle. Its EAGLE Series order covers approximately 3,000 vehicles, with deliveries expected to begin in 2027.

Allison continues to develop conventional products for fuel efficiency and lower emissions, as well as hybrid and fully electric propulsion systems. The company expects to realize its $120 million annual run rate synergy target from the off-highway acquisition by the end of 2029, through procurement, manufacturing and organizational initiatives.

Structural risks

• Competition and technology: Allison faces competing transmission and propulsion manufacturers, including customers that make their own systems. Its success also depends on developing new products and responding to changing customer needs.

• Acquisition integration: Allison expects significant integration costs for the acquired off-highway business. Integration can involve difficulties combining manufacturing, logistics, personnel and other operations, as well as the potential loss of customers, employees or suppliers.

• Debt and financing: Indebtedness can restrict Allison’s activities, reduce cash available for other purposes and make it harder to meet obligations. Variable-rate borrowing also exposes it to higher interest rates.

• Materials and demand: Commodity inflation creates a near-term margin headwind before Allison recovers a substantial portion of higher costs from customers. Demand also differs across its end markets; Allison says agriculture had not yet turned positive in the second quarter of 2026.

• Regulation and international operations: Emissions rules can affect Allison’s products and customers. Its international operations face risks from tariffs, trade restrictions, currency controls and differing legal requirements. Allison and its customers are assessing the potential effects of an EPA proposal.

Bottom line

Our reading

Allison is an engineered-equipment supplier whose business rests on selling propulsion systems to manufacturers and supporting vehicles throughout their working lives. Its acquisition broadens the products and markets it serves, while adding integration work and debt. The business remains exposed to manufacturer demand, competing propulsion technologies and the timing of material-cost recovery.
