Westport Fuel Systems Inc. ("Westport" or the "company") (TSX:WPRT Nasdaq: WPRT), today announced that it has changed its name to Aetherion Technologies Inc. ("Aetherion"). The new name reflects the company's sharpened focus on delivering proven, commercially ready technologies that enable affordable, lower-emission heavy-duty transportation.
Heavy-duty engines move the food, medicine, construction materials and goods that keep life in motion. For more than a century, diesel has powered that work because it is powerful, proven and ubiquitous, but it is also difficult to affordably decarbonize. Aetherion's systems deliver diesel-grade performance and economics on cleaner fuels, giving fleets a practical path to lower emissions by leveraging their existing engine platforms. In many cases, lower-cost alternative fuels can also reduce operating costs compared with diesel.
Aetherion's new identity builds on the fundamental concepts on which Professor Philip Hill co-founded Westport in 1995 and invented HPDI™ fuel system technology: keep the diesel engine that has moved the world for decades, but change the fuel so it runs cleaner.
The name Aetherion reinforces that mission. Drawing on two Greek roots—aithēr, the clean air of the upper sky, and ion, meaning motion or energy—to reflect what the company delivers: cleaner power for the engines that move the world. It signals a return to the founders' original vision and underscores Aetherion's commitment to practical, scalable solutions that help fleets transition to lower‑emission fuels insulated from oil‑driven price shocks.
Aetherion's portfolio includes a majority ownership interest in Cespira™, a joint venture with Volvo Group focused on the HPDI fuel system technology, as well as wholly owned high-pressure compressed natural gas (CNG) fuel storage system, high-pressure systems and components and control technologies. Together, these technologies support natural gas, renewable natural gas which includes biogas and bioLNG (RNG) and hydrogen applications, enabling original equipment manufacturers (OEMs) and commercial fleets to cost effectively meet performance requirements, evolving regulatory obligations and climate targets. Market drivers for Aetherion's solutions include rising demand for cost‑effective long‑haul alternatives, tightening emissions standards and broader adoption of practical, lower‑emission fuels.
"Aetherion represents both our origin and our future," said Dan Sceli, CEO. "Fleets and OEMs need technologies that preserve the performance they're accustomed to, at a lower cost, while helping them meet increasingly complex regulatory and climate objectives. Our new identity underscores the mission that guides our work: delivering proven, scalable systems that make cleaner transportation achievable today and sustainable for the long term. To us, Aetherion suggests cleaner air, forward motion and the energy driving change in heavy-duty transportation. While our name is changing, our dedication to our customers, partners and shareholders remains steadfast."
Cespira's HPDI Technology Anchors Aetherion's Heavy‑Duty Strategy
Aetherion's interest in Cespira is a strategic asset that combines proven commercial traction with multiple pathways to long-term value creation. HPDI fuel systems, Cespira's proprietary technology, is a mature, commercially validated technology, operating in more than 12,000 trucks worldwide. It addresses a central industry challenge: reducing emissions without compromising performance or economics, and delivers one of the lowest total costs of ownership among heavy-duty and high-horsepower powertrain options. Cespira is progressing toward profitability and self-sufficiency, reporting revenue of $27.1 million in the second quarter of 2026, a 125% increase from the same period last year, reflecting accelerating fleet adoption and expanding geographic reach.
HPDI fuel systems deliver diesel-grade performance with strong total-cost-of-ownership economics and can reduce greenhouse gas emissions by 20% and up to 100% using bioLNG, Hydrogen and HVO. In addition to its established liquified natural gas (LNG) and bioLNG applications, HPDI can expand through additional OEM adoption, CNG and RNG applications in North America, and hydrogen-fueled solutions that offer an affordable, scalable pathway to deeper decarbonization. Together, these opportunities broaden the addressable market and create demand for complementary high-pressure gaseous fuels storage and supply solutions within Aetherion's product portfolio.
Implementation and Trading Details
The new brand brings the company's identity into closer alignment with its technology portfolio, market opportunities and long-term direction, but will have no impact on operations, ownership or commitments to customers, partners, employees and shareholders.
The company expects its common shares to begin trading as Aetherion Technologies Inc. on the Toronto Stock Exchange and Nasdaq on or about October 23, 2026, under the ticker symbols AETR, respectively, subject to final exchange approvals. Until such time, trading will continue under the ticker symbol WPRT. The company's CUSIP and ISIN numbers will change in connection with the name change. Shareholders are not required to take any action, and existing share certificates will continue to represent shares of the renamed company.
