Westport (WPRT) Q3 2025: SUSPIRA JV Grows 19%, Reshaping Heavy-Duty Focus
Westport’s Q3 marks a structural shift as the SUSPIRA joint venture, heavy-duty segment, and CNG innovation define the post-divestiture landscape. The light-duty exit compresses revenue but sharpens strategic focus, while SUSPIRA’s volume gains and new OEM traction signal a path to scale. Investors should watch operating discipline and the pace of OEM adoption as Westport pivots toward sustainable transportation growth.
Summary
- SUSPIRA Momentum: JV revenue climbs on higher volumes, validating Westport’s heavy-duty strategy reset.
- Operating Model Evolution: Divestiture and cost actions streamline structure, but margin and scale remain critical watchpoints.
- OEM Pipeline Watch: Near-term growth hinges on demonstration fleet success and new customer adoption cycles.
Performance Analysis
Westport’s Q3 2025 results reflect a business in active transformation, with headline revenue dropping sharply due to the completed divestiture of the light-duty segment. The remaining core is now centered on high-pressure controls and the SUSPIRA joint venture, which together form the backbone of the new, focused Westport. SUSPIRA, the heavy-duty alternative fuel systems JV with Volvo, posted a 19% revenue increase year over year to $19.3 million, driven by higher system volumes and aftermarket sales as supply chain constraints eased. However, SUSPIRA’s gross margin remains negative, underscoring the need for further volume scaling to reach profitability.
High-pressure controls and systems revenue was steady at $1.6 million, with gross margin improvements attributable to engineering services. Adjusted EBITDA moved deeper negative, reflecting the loss of scale from the divested segment and increased R&D and SG&A, partially offset by lower operating costs. Foreign exchange swings and one-time restructuring costs further widened net losses. Cash generation improved due to lower working capital needs and proceeds from the light-duty sale, leaving Westport with $33.1 million in cash and only $3.9 million in debt, positioning the company to weather further transformation.
- Revenue Compression: Light-duty exit drove a sharp top-line drop, but clarified segment economics and focus.
- SUSPIRA Scaling: JV’s 19% growth is the central lever for future heavy-duty expansion, though margins remain negative pending scale.
- Cost Structure Reset: Operating expenses and CapEx are being aggressively reduced to align with the smaller, heavy-duty-centric model.
Westport’s financials now reflect a leaner, more targeted business, but the transition phase will test management’s ability to drive scale and operating leverage from the new core.
Executive Commentary
"The successful completion of the light duty segment divestiture marked an important milestone in simplifying our business and concentrating on our core heavy duty and alternative fuel systems... This solid financial position enables us to execute our strategic priorities and engage more proactively with OEM and fleet partners who are increasingly seeking affordable, low-carbon solutions."
Dan Selay, Chief Executive Officer
"Looking ahead, we expect more cost reductions on a relative basis in the near future as we adjust to become a smaller organization after the divestiture of the light duty segment... Our business is focused on the right markets for us, and we are continually looking at ways to streamline our operations."

Strategic Positioning
1. Heavy-Duty Focus and SUSPIRA JV
Westport’s strategic reset is anchored by the SUSPIRA joint venture, which serves as both technology showcase and growth engine for heavy-duty natural gas and hydrogen fuel systems. With SUSPIRA’s revenue up 19% and a second OEM now engaged in trials, Westport is positioning itself as a leader in sustainable transport solutions. The path to profitability, however, depends on scaling volumes and converting trials into commercial agreements.
2. Manufacturing Realignment and Geographic Diversification
Post-divestiture, Westport is relocating high-pressure control manufacturing from Italy to Canada and China, aligning production with target markets and lowering cost-to-serve. The Chinese market, the world’s largest for hydrogen components, is now directly served from local capacity, while the Canadian facility is set to address North American demand as natural gas adoption accelerates in long-haul trucking.
3. CNG System Innovation for North America
Westport’s new CNG solution, integrating storage, controls, and engine management, targets the North American long-haul trucking market where CNG is gaining traction as a diesel alternative. Demonstration fleets will be deployed first, with commercialization contingent on successful trials and EPA certification. This initiative expands Westport’s TAM (total addressable market) and leverages SUSPIRA’s proven HPDI technology for new geographies.
4. Cost Discipline and Capital Allocation
Management is targeting a 60% CapEx and 15% SG&A reduction in 2026, reflecting a commitment to cash conservation and operational agility. The balance sheet, strengthened by divestiture proceeds, supports ongoing investment in SUSPIRA and the CNG platform, but future capital contributions to the JV are still required to reach standalone scale.
5. OEM Pipeline and Market Adoption
OEM engagement is broadening, with a new customer trial underway and ongoing discussions across global truck makers. The technology is now proven, with the challenge shifting to timing and market readiness for commercial adoption. Legislative changes in Europe and biogas crediting could accelerate demand, while North American fleets are beginning to prioritize total cost of ownership and emissions reduction.
Key Considerations
This quarter marks a decisive break from Westport’s legacy structure, with the company now fully committed to heavy-duty and alternative fuel system markets. The strategic context is defined by the need to scale SUSPIRA, align manufacturing with demand centers, and prove out CNG solutions in North America.
Key Considerations:
- SUSPIRA’s Volume Ramp: Sustainable profitability depends on converting OEM trials to multi-year commercial contracts and reaching higher system volumes.
- Margin Inflection Point: Negative margins at SUSPIRA require careful monitoring; cost leverage must materialize as scale builds.
- Manufacturing Execution: Relocation to Canada and China must be completed without major disruption, as inventory buffer is limited and lower revenues are expected during the ramp.
- CNG Commercialization Timeline: North American demonstration fleets and EPA certification are gating items for new revenue streams.
- Capital Needs for JV: Additional SUSPIRA capital contributions are planned in 2026, impacting cash runway and requiring ongoing balance sheet vigilance.
Risks
Westport faces execution risk in scaling SUSPIRA and ramping new CNG solutions, especially as both segments require OEM adoption cycles that are lengthy and highly dependent on regulatory and market shifts. Margin pressure will persist until volumes reach breakeven, and any delays in manufacturing relocation or demonstration fleet success could impact revenue visibility. Ongoing capital contributions to SUSPIRA and exposure to foreign exchange swings add further uncertainty to near-term cash flow and profitability.
Forward Outlook
For Q4 2025, Westport guided to:
- Continued cost reductions as restructuring actions take hold
- Initial production from Canadian and Chinese facilities by year-end
For full-year 2025, management maintained focus on:
- SUSPIRA volume growth and additional OEM engagement
- 60% CapEx and 15% SG&A reductions targeted for 2026
Management highlighted several factors that will shape the coming quarters:
- OEM trial feedback and demonstration fleet performance as signposts for commercial adoption
- Legislative developments in Europe and North America influencing natural gas and biogas adoption
Takeaways
Westport’s strategic overhaul is underway, with SUSPIRA and CNG innovation now the primary vectors for growth. The company’s ability to convert technical validation into commercial scale, maintain cost discipline, and navigate capital needs will define the next phase.
- Heavy-Duty Pivot: The business is now fully aligned with heavy-duty and alternative fuel systems, with legacy distractions removed and a clear growth thesis tied to SUSPIRA and CNG adoption.
- Margin and Scale Watch: Persistent negative margins at SUSPIRA and the need for further OEM wins mean investors must closely track the conversion of trials to contracts and the pace of volume ramp.
- Execution in Transition: Manufacturing shifts and cost actions are necessary, but introduce operational risk that must be managed to avoid further revenue compression or customer disruption.
Conclusion
Westport’s Q3 2025 is a transition quarter that crystallizes its post-divestiture identity: a focused, capital-disciplined player in heavy-duty alternative fuels. SUSPIRA’s growth and new OEM traction are encouraging, but the path to profitability remains dependent on scale, cost control, and successful CNG commercialization.
