Allison Transmission Holdings, Inc.

Overview

Allison Transmission Holdings, Inc. and its subsidiaries are a global leader in high-performance mobility and work solutions for the industrial market. The company was founded in 1915 and is headquartered in Indianapolis, Indiana. Allison is publicly traded on the NYSE under the ticker ALSN.

On January 1, 2026, Allison completed the acquisition of an Off-Highway business, expanding its drivetrain and propulsion offerings for on-highway, off-highway, and defense applications. The 2025 Form 10-K figures do not reflect that acquisition.

Core business

• Principal product focus: the world’s largest manufacturer of fully automatic transmissions for medium- and heavy-duty commercial vehicles and medium- and heavy-tactical U.S. defense vehicles.
• Expanded offering after the acquisition: drivetrain and propulsion solutions for off-highway applications (drive & motion systems).
• End markets served:
  • On-highway vehicles (distribution, refuse, construction, fire and emergency, etc.)
  • Buses (school, transit, coach)
  • Motorhomes
  • Off-highway vehicles and equipment (energy, mining, construction, agriculture)
  • Defense vehicles (tactical wheeled and tracked)
• Technology emphasis:
  • Introduced the world’s first fully automatic transmission for commercial vehicles more than 75 years ago.
  • Focus on electronic controls and software for propulsion systems to optimize performance, fuel efficiency, and maintenance.
  • Developing electric hybrid and fully electric propulsion solutions; fully electric propulsion is more established in bus markets than in medium- and heavy-duty commercial vehicles.

Corporate structure and scope

• Two operating business units:
  • Allison Transmission
  • Allison Off-Highway Drive & Motion Systems
• The acquisition expands the customer base and product portfolio across on-highway, off-highway, and defense end markets.

Notes

• The Acquired Off-Highway Business closed on January 1, 2026; 2025 figures do not reflect that acquisition.

Summary

Allison is a leading manufacturer of fully automatic transmissions for medium- and heavy-duty vehicles and has grown its off-highway and defense capabilities through the recent acquisition. In 2025, the company reported about $3.01 billion in net sales, with the majority of revenue coming from North America and a notable contribution from service parts and support equipment. The business operates through two main units and serves a broad set of end markets via a large distributor and dealer network.
