The primary clear emerging threat for Westport Fuel Systems (WPRT) is the rapid and accelerating global shift towards Battery Electric Vehicles (BEVs) and Fuel Cell Electric Vehicles (FCEVs) as the preferred zero-emission solutions across light-duty, medium-duty, and heavy-duty commercial vehicle segments.

• Major original equipment manufacturers (OEMs) are committing substantial resources and production capacity to BEV and FCEV powertrains for trucks, buses, and off-highway vehicles, driven by increasingly stringent global emissions regulations (e.g., California's Advanced Clean Trucks rule, EU CO2 standards for heavy-duty vehicles) and a push for absolute zero tailpipe emissions.
• While Westport Fuel Systems focuses on alternative fuel internal combustion engines (natural gas, propane, and hydrogen ICE), these solutions, even hydrogen ICE, face competition from BEV and FCEV which are often positioned as truly "zero-emission" at the tailpipe, particularly for applications requiring long range or high power. If the adoption rate of BEVs and FCEVs in these segments outpaces the market penetration of Westport's alternative fuel ICE technologies, it could significantly constrain their addressable market and growth opportunities.
• Additionally, within the hydrogen ecosystem, the accelerated maturity and increasing industry preference for hydrogen fuel cell electric vehicles (FCEVs) over hydrogen internal combustion engines (ICE) represent a specific competitive threat. FCEVs typically offer higher energy efficiency and emit only water, whereas hydrogen ICE, while carbon-free with green hydrogen, still produces NOx emissions during combustion. If FCEV technology becomes more cost-effective, widely adopted, and better supported by infrastructure than hydrogen ICE, it could limit the market for Westport's hydrogen ICE offerings.

Westport Fuel Systems (WPRT) operates in several addressable markets related to alternative fuel systems and components for transportation and industrial applications, primarily focusing on natural gas, renewable natural gas, and hydrogen technologies. The main products and services include High-Pressure Direct Injection (HPDI) fuel systems, high-pressure controls and systems, and advanced engine management controllers and software that enable vehicles to run on alternative fuels.

The addressable market sizes for Westport Fuel Systems' main products and services are as follows:

• Automotive Natural Gas Vehicle (NGV) Market (Global): The global automotive natural gas vehicle market was estimated to be between USD 12.85 billion and USD 34.5 billion in 2025, with projections to reach between USD 16.62 billion by 2029 and USD 40.9 billion by 2030, growing at a Compound Annual Growth Rate (CAGR) ranging from 2.8% to 7.1% during the respective forecast periods. The Asia-Pacific region held the largest share of this market, accounting for 54.0% in 2024.
• Renewable Natural Gas (RNG) Market (Global): The global renewable natural gas market is estimated to be valued between USD 15.20 billion and USD 15.72 billion in 2025. It is projected to reach between USD 26.57 billion by 2032 and USD 32.51 billion by 2034, with CAGRs ranging from 8.0% to 8.41% over the forecast periods. North America dominated this market in 2024, holding approximately 35% to 45% of the global share. The transportation fuel segment constituted the largest application share in the global RNG industry in 2024, at approximately 56%.
• Hydrogen Internal Combustion Engines / Hydrogen Combustion Engine Market (Global): The global market for hydrogen internal combustion engines and hydrogen combustion engines is estimated to be valued between USD 3.6 million and USD 54.16 billion in 2025. It is forecasted to reach between USD 51.76 billion by 2034 and USD 105.61 billion by 2032, with CAGRs ranging from 9.94% to 142.9%. Europe is expected to account for a significant portion, around 40.5% by 2036, while the Asia-Pacific region is projected to dominate with a 35.3% share in 2025 and is considered the fastest-growing region.

Westport Fuel Systems (WPRT) anticipates several key drivers for future revenue growth over the next two to three years, primarily stemming from its strategic focus on heavy-duty and alternative fuel systems following the divestiture of its Light-Duty segment in July 2025.

1. Increased volumes and market penetration of the Cespira joint venture's High-Pressure Direct Injection (HPDI) systems: The Cespira joint venture (also referred to as Sospira) is consistently highlighted as a significant growth area, having seen a 19% increase in revenue in both Q3 2025 and Q2 2025 compared to the prior year. Westport's strategy for Cespira involves delivering demonstrated volume growth, increasing its OEM presence, and expanding geographically, particularly in regions like Europe, India, and South America, where there's rising adoption and market opportunities for HPDI trucks.
2. Growth in the High-Pressure Controls & Systems business: This segment is considered a core pillar of Westport's growth strategy, focusing on providing critical components for fuel-agnostic platforms. While this segment experienced some revenue decline in Q2 and Q3 2025 due to a slowdown in the hydrogen industry and the relocation of production facilities, the company expects manufacturing facilities in Canada and China to be online by year-end, which should support future growth and capture market opportunities.
3. Development and commercialization of new alternative fuel solutions: Westport is committed to technological leadership and developing new solutions for cleaner energy. A specific driver mentioned is the development of a new Compressed Natural Gas (CNG) solution for the North American market. The company's expertise in natural gas, renewable natural gas, and hydrogen systems positions it to capitalize on the broader trend towards decarbonizing commercial transport.
