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.
