Westport Fuel Systems is showcasing a new high-pressure compressed natural gas (CNG) fuel storage system paired with Cespira’s on‑engine HPDI™ fuel system in its first North American demonstration at ACT Expo 2026 in Las Vegas.
The system is installed on a Volvo VNL 300 truck rated at 500 horsepower and 1,850 lb‑ft of torque, with fuel efficiency on CNG closely comparable to the diesel version. Westport highlights up to 10 miles per gallon equivalent and a driving range of more than 600 miles, aiming to deliver diesel‑like performance with lower emissions for heavy‑duty fleets.
The HPDI platform can run on CNG, renewable natural gas and hydrogen or blends, offering OEMs a path to adopt natural gas today while keeping an option to transition to hydrogen using largely the same engine architecture.
Westport Fuel Systems reported fourth quarter and full year 2025 results showing a much smaller business after its Light-Duty divestiture and growing dependence on its Cespira joint venture. Full-year revenue from continuing operations fell 43% to $23.3 million, while net loss from continuing operations narrowed slightly to $29.6 million.
Including discontinued operations tied to the sold Light-Duty segment, total net loss widened to $61.6 million, and Adjusted EBITDA loss increased to $17.3 million. Cespira generated $77.4 million of revenue but posted a net loss and drove a $15.8 million equity-method loss for Westport.
Liquidity remains tight: Westport ended 2025 with $27.2 million in cash and $2.9 million of long-term debt, yet projects that existing cash will not fund operations for the next 12 months. Management plans to seek new financing and formally concluded there is substantial doubt about its ability to continue as a going concern.
Westport Fuel Systems reported 2025 revenue of $23.3 million, down 43% from 2024, as its Heavy-Duty OEM transitional services wound down and hydrogen-related demand softened. The company recorded a net loss from continuing operations of $29.6 million, slightly improved from a $31.3 million loss a year earlier.
Cash and cash equivalents were $27.2 million at year-end, and management identified a material uncertainty about the ability to continue as a going concern, noting projected cash shortfalls over the next 12 months without additional funding. Adjusted EBITDA was a negative $17.3 million, widening from a negative $11.4 million.
Westport’s 55%-owned joint venture Cespira generated 2025 revenue of $77.4 million, up 80% year over year, reflecting growth in HPDI fuel systems. The company also closed the $79.5 million sale of its Light-Duty segment, is consolidating manufacturing into new Canadian and Chinese facilities, and disclosed a 2026 ransomware incident it does not currently view as materially impacting operations.
Westport Fuel Systems Inc. filed a Form 6-K to furnish a press release announcing the timing of its Q4 2025 and full year 2025 financial results. The company plans to release results on April 23, 2026 after market close and will host a conference call and webcast on April 24, 2026 at 10:00 a.m. ET to discuss the results and other corporate developments.
Westport Fuel Systems filed a Form 6-K to share a bi-weekly update on a management cease trade order that followed a March 2026 cybersecurity incident and delayed 2025 annual filings. The order restricts trading in the company’s securities by the CEO and CFO but not by other investors.
The investigation of the cyber incident has concluded, including a review of internal controls over financial reporting, and management determined those controls were not deficient. A revised audit scope for the 2025 annual financial statements and related filings is now underway, and Westport plans to complete and file them as soon as possible.
Westport states there has been no material change to the earlier cyber incident disclosure, does not expect additional specified defaults under the Canadian policy governing the order, and confirms there is no undisclosed material information. The company will continue bi-weekly status updates until the annual filings are made.
Westport Fuel Systems Inc. reports that the British Columbia Securities Commission has issued a temporary management cease trade order restricting trading in the company’s securities by its CEO and CFO after a previously disclosed cybersecurity incident delayed its 2025 year-end reporting. The company has missed the March 31, 2026 deadline for filing its audited financial statements, management’s discussion and analysis, CEO/CFO certifications, and annual information form for the year ended December 31, 2025. Westport is working with its auditors to assess the incident’s impact on financial reporting and internal controls and plans to complete any additional audit work, revise its annual documents if necessary, and file them as promptly as possible while providing bi-weekly status updates under National Policy 12-203.
Westport Fuel Systems announced that Cespira’s hydrogen HPDI fuel system will be used by Volvo in on-road testing of heavy-duty hydrogen trucks. Volvo has indicated plans for a commercial launch before 2030, marking a significant development step for this joint venture technology.
The hydrogen HPDI system is based on Cespira’s existing HPDI platform, already deployed in over 10,000 Volvo LNG trucks worldwide. Westport highlights that hydrogen HPDI can deliver nearly 100% CO2 reductions versus diesel while preserving OEMs’ existing engine architectures and manufacturing investments, and it may qualify as a Zero Emissions Vehicle under EU CO2 standards.
Westport Fuel Systems reports a cybersecurity incident that led to unauthorized access on March 17, 2026 to certain internal IT business applications and business and employee information. The company engaged external experts, activated its incident response protocol, and is enhancing security measures while its investigation continues.
Manufacturing systems run on separate servers, so production, order fulfillment, and operational delivery remain unaffected, and Westport does not currently expect a material impact on daily operations. However, because the incident occurred during the year-end reporting cycle, Westport expects to file its annual information form, audited financial statements, MD&A, and related CEO/CFO certificates after the March 31, 2026 deadline and anticipates filing on or before May 30, 2026. Westport and its auditor will assess the incident’s impact on financial reporting controls and complete any additional audit work. The company has applied for a temporary management cease trade order and will follow alternative information guidelines under National Policy 12-203.
