from the latest 10-K, 10-Q and 8-K eventsWestport Fuel Systems Inc. is a Vancouver-based, Nasdaq-listed developer and supplier of alternative-fuel engine and fuel-delivery systems that has seen revenue shrink from $312.4 million in 2021 to $23.3 million in 2025.
What they do
Westport Fuel Systems designs and supplies lower-emission propulsion technologies, including components and systems that allow engines to run on alternatives to diesel such as natural gas. It files as a foreign private issuer on Form 20-F and is incorporated in Alberta, Canada, with principal offices in Vancouver. The company sells into engine and vehicle markets through its own operations and joint ventures.
Revenue drivers
- Alternative-fuel engine and fuel-system products — Westport generates revenue by selling alternative-fuel engine and fuel-delivery system products and components to engine and vehicle manufacturers and aftermarket customers.
- Engineering and development services — The company earns revenue from engineering and development work performed for original equipment manufacturers and other customers.
- Joint ventures and affiliates — Westport participates in joint ventures, including a fuel-systems joint venture, that supply products to OEM customers and can contribute revenue and equity income.
Recent performance
Revenue fell from $312.4 million in 2021 to $68.2 million in 2023, $40.7 million in 2024 and $23.3 million in 2025. Net loss was $32.7 million in 2022, $49.7 million in 2023, $21.8 million in 2024 and $61.6 million in 2025; diluted EPS was -$3.56 in 2025. Operating cash flow swung from positive $7.2 million in 2024 to negative $14.2 million in 2025. Quarterly revenue was $14.1 million in Q2 2024, $4.9 million in Q3 2024, $12.5 million in Q2 2025 and $1.6 million in Q3 2025, showing sharp quarter-to-quarter volatility.
Strategy
Westport's stated direction centers on supplying lower-emission propulsion systems, including natural gas and other alternative fuels, to engine and vehicle manufacturers. The company continues to invest in research and development of these fuel systems and in its engineering capabilities. Its joint ventures remain part of how it reaches OEM customers. The filings describe the business as subject to supply, demand and pricing risks for lower/zero emission propulsion systems.
Risks
- Revenue decline — Revenue has contracted for four consecutive years, from $312.4 million in 2021 to $23.3 million in 2025, with a particularly weak $1.6 million in Q3 2025.
- Persistent losses — Westport reported net losses in each of 2022 through 2025, including a $61.6 million loss in 2025 and diluted EPS of -$3.56.
- Negative operating cash flow — Operating cash flow turned negative at -$14.2 million in 2025 after a positive $7.2 million in 2024, reversing the prior year's cash generation.
- Dependence on alternative-fuel demand — The filings cite supply of, demand for and price of lower/zero emission propulsion systems as key risks, making results sensitive to adoption of those technologies.
Outlook
The filing reiterates that supply, demand and pricing for lower/zero emission propulsion systems are key uncertainties affecting future results. No specific revenue or earnings guidance is provided in the excerpted material. Management continues to invest in research and development and engineering around alternative-fuel systems.
