## Overview

Allison Transmission Holdings Inc. designs and manufactures propulsion solutions centered on fully automatic transmissions, electric hybrid propulsion, and fully electric propulsion systems for commercial and defense vehicles. Founded in 1915 and headquartered in Indianapolis, the company has built a large installed base that supports a meaningful aftermarket in service parts, fluids, remanufactured products, and support equipment. Its business is organized around on-highway, off-highway, defense, and aftermarket end markets, with sales reaching OEMs, body builders, distributors, dealers, and large end users. In 2026, the company expanded further into off-highway drivetrain and motion systems through the acquisition of the Acquired Off-Highway Business, broadening its exposure beyond traditional on-highway transmissions.

## Customers

Allison sells primarily to commercial vehicle OEMs, body builders, and defense OEMs that integrate its transmissions and propulsion systems into finished vehicles and equipment. A large portion of demand also comes from end users in vocational fleets such as transit, refuse, fire and emergency, distribution, construction, mining, and agriculture, where uptime and durability are critical. The company’s aftermarket business serves the installed base through distributors and dealers that buy genuine parts, fluids, remanufactured units, and support equipment to keep vehicles operating. Large fleet accounts and national accounts matter because they influence specification decisions and can drive repeat demand across multiple vehicle platforms. Defense customers are strategically important because programs are long-cycle, technically demanding, and tied to government procurement and OEM relationships.

- **Commercial vehicle OEMs** (primary) — Buy transmissions and propulsion systems for new buses, trucks, and specialty vehicles because Allison products are specified for durability, performance, and ease of integration.
- **Aftermarket distributors and dealers** (primary) — Buy genuine service parts, fluids, remanufactured products, and support equipment to service the installed base and preserve vehicle uptime.
- **Fleet operators and large end users** (primary) — Buy vehicles equipped with Allison systems or aftermarket support because they value reliability, lower downtime, and predictable maintenance.
- **Defense OEMs and government programs** (secondary) — Buy tracked and wheeled defense propulsion solutions for mission-critical vehicle platforms with long program cycles and technical requirements.
- **Off-highway equipment manufacturers** (emerging) — Buy drivetrain and motion systems for construction, mining, agriculture, and industrial equipment, especially after the 2026 acquisition.

- Commercial vehicle OEMs that specify Allison transmissions in new vehicles
- Body builders that integrate propulsion systems into specialty applications
- Transit, refuse, fire, and emergency fleets that need reliable uptime
- Defense OEMs and program stakeholders for tracked and wheeled vehicles
- Distributors and dealers that buy parts, fluids, and remanufactured units
- Large end users and national accounts that influence platform adoption

## Geography

Allison serves customers across North America, Asia, Europe, South America, and Africa, but its revenue base remains heavily concentrated in North America, which generated approximately 76% of revenue in 2025. Outside North America, the company relies on regional sales, service, and customer integration teams to support OEMs and end users in local markets. Manufacturing is distributed across the United States, India, Hungary, and other locations, which helps support global delivery and local responsiveness. The company also maintains customization and parts distribution centers in the United States, the Netherlands, Brazil, China, Hungary, India, and Japan, reflecting the importance of aftermarket service and regional support. This geographic footprint exposes Allison to foreign currency, geopolitical, and supply-chain risks, while also giving it access to non-U.S. growth opportunities.

- **North America** (76%) — Approximate 2025 revenue concentration disclosed in the annual report.
- **Rest of World** (24%) — Residual share inferred from the disclosed North America concentration.

- North America generated about 76% of 2025 revenue and is the core profit pool
- Customers are also served across Asia, Europe, South America, and Africa
- Primary manufacturing is in Indianapolis, with additional production in India and Hungary
- Fully electric propulsion is produced in Auburn Hills, Michigan
- Parts distribution and customization centers support local service in multiple regions
- International operations increase FX and geopolitical exposure but broaden growth options

## Strategy

Allison’s strategy is to defend its core on-highway transmission franchise while expanding into adjacent propulsion technologies and end markets. The 2026 acquisition of the Acquired Off-Highway Business is a major step toward a broader drivetrain and motion portfolio, reducing dependence on traditional on-highway demand. The company is also investing in fuel-efficient conventional products, hybrid systems, and fully electric propulsion to stay relevant as customer requirements evolve. Its global distributor and dealer network remains central to the strategy because it supports specification, service, and aftermarket pull-through. Defense and off-highway expansion also diversify the business toward markets with different demand cycles and longer-term program opportunities.

- **Integrate the Acquired Off-Highway Business** (short-term) — Integration determines whether Allison can realize the expected portfolio breadth, customer diversification, and cross-selling benefits.
- **Expand electrification and hybrid offerings** (medium-term) — Electric and hybrid products help the company participate in future propulsion transitions and win new platform specifications.
- **Grow defense and specialty end markets** (medium-term) — Defense programs and specialty vocational applications can provide differentiated demand and reduce reliance on cyclical on-highway volumes.

- Protect the core automatic transmission franchise in North America
- Expand into off-highway drivetrain and motion systems through acquisition
- Grow electric and hybrid propulsion offerings for evolving vehicle platforms
- Use the distributor/dealer network to drive aftermarket pull-through
- Target defense and specialty applications with long-cycle program wins
- Improve fuel efficiency and emissions performance of conventional products

## Risks

Allison faces cyclical demand risk because many of its end markets, including commercial vehicles, construction, mining, and energy-related equipment, are tied to broader industrial and economic conditions. The company is also exposed to customer concentration, as sales were concentrated among its top five OEM customers in 2025, so the loss or consolidation of a major customer could materially reduce volume. Supply-chain disruption, raw material inflation, and labor cost inflation can pressure margins because the business depends on manufactured components and a global production footprint. Cybersecurity is a material operational risk because attacks could disrupt manufacturing, compromise proprietary technology, or affect in-product control modules. International expansion and the off-highway acquisition add integration, geopolitical, foreign exchange, and execution risk, while the dealer network creates reputational dependence on third-party service quality.

- **Customer concentration** [high] — Sales were concentrated among the top five OEM customers in 2025, so a lost platform or customer consolidation could materially reduce revenue.
- **Cyclical end-market demand** [high] — Commercial vehicle, construction, mining, and energy-related demand can fall sharply in weaker economic conditions.
- **Cybersecurity incidents** [high] — Operational systems, manufacturing, and in-product propulsion controls could be disrupted or compromised by cyberattacks.
- **Acquisition integration risk** [medium] — The Acquired Off-Highway Business must be integrated successfully to realize expected strategic and financial benefits.
- **Foreign exchange and geopolitical exposure** [medium] — A larger international footprint increases sensitivity to currency swings, trade disruption, and regional instability.

- Customer concentration among top OEMs can quickly reduce volumes if a platform is lost
- Cyclical end markets can weaken demand for commercial and off-highway products
- Supply shortages and raw material inflation can compress margins
- Cyberattacks could disrupt operations, IP, or vehicle control systems
- Foreign exchange and geopolitical exposure rise with international operations
- Acquisition integration risk could delay synergies and distract management
- Dealer and distributor performance affects brand reputation and aftermarket service

## Accounting

Allison’s reported results are sensitive to estimates around sales incentives and government price reductions, both of which are recorded as reductions to net sales and can move earnings if actual usage differs from assumptions. The company also carries goodwill and other intangible assets that require annual impairment testing, and management’s valuation assumptions such as growth, margins, and discount rates can materially affect whether non-cash charges are recorded. Because the business has a large aftermarket and installed base, revenue mix between new equipment, parts, and remanufactured products can shift quarter to quarter and affect comparability. The 2026 acquisition adds further accounting complexity through purchase accounting, integration-related estimates, and potential future impairment risk if the acquired business underperforms. Investors should also watch foreign currency effects and any provisions tied to customer programs or government contracts, since these can change reported margins without reflecting underlying demand trends.

- **Sales incentives and rebates** — A 10% change in sales incentives was disclosed as roughly an $8 million earnings impact.
- **Government price reduction reserves** — A 10% change in the reserve was disclosed as roughly a $5 million earnings impact.
- **Goodwill impairment** — Could materially affect reported earnings and equity if assumptions deteriorate.
- **Acquisition accounting** — May affect amortization, goodwill, and future impairment risk.

- Sales incentives and rebates reduce net sales and depend on management estimates
- Government price reduction reserves can change earnings when contract audits are finalized
- Goodwill and intangible assets require annual impairment testing using valuation assumptions
- Revenue mix between OEM sales and aftermarket parts can create quarter-to-quarter volatility
- Acquisition accounting may create new intangibles, goodwill, and integration-related estimates
- Foreign currency movements can affect reported results from international operations
