Allison Transmission Holdings files its annual report describing a global drivetrain business centered on fully automatic transmissions and emerging electric propulsion systems. In 2025, about 76% of revenue came from North America, with net sales of $1,540 million in North America on‑highway and $507 million outside North America on‑highway.
Other 2025 net sales included $53 million in global off‑highway, $267 million in defense, and $643 million from service parts, support equipment and other, reflecting a sizable aftermarket base. On January 1, 2026, Allison completed the acquisition of Dana’s Off‑Highway Drive & Motion Systems business, adding roughly 8,000 employees and expanding into broader drivetrain and motion solutions across off‑highway end markets.
The report highlights competitive pressure from manual, automated manual and electric propulsion technologies, along with risks from supply chain volatility, inflation, labor costs, unionized workforces, customer concentration, cyclical demand in sectors like energy and construction, cybersecurity, geopolitical tensions and growing environmental and sustainability regulation. Management cautions that integration of the acquired off‑highway business involves significant costs and execution risk and that failure to realize expected synergies or manage a larger global footprint could adversely affect future results.
