Westport Fuel Systems Rebrands as Aetherion Technologies, Focused on Heavy-Duty Clean Transport Solutions
NASDAQ: WPRT

Overview

Westport Fuel Systems Inc. ("Westport" or the "company") announced that it has changed its name to Aetherion Technologies Inc. ("Aetherion"), according to the company. The company stated that the new name reflects its sharpened focus on delivering proven, commercially ready technologies that enable affordable, lower-emission heavy-duty transportation.

According to the company, 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. The company said the name draws on two Greek roots, aither, 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.

Key Highlights

  • Westport Fuel Systems Inc. has changed its name to Aetherion Technologies Inc., according to the company.
  • 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 symbol AETR, subject to final exchange approvals.
  • Until such time, the company stated that trading will continue under the ticker symbol WPRT.
  • The company's CUSIP and ISIN numbers will change in connection with the name change, and shareholders are not required to take any action, with existing share certificates continuing to represent shares of the renamed company, according to the company.
  • Aetherion's portfolio includes a majority ownership interest in Cespira, a joint venture with Volvo Group focused on HPDI fuel system technology, as well as wholly owned high-pressure compressed natural gas (CNG) fuel storage systems, high-pressure systems and components, and control technologies, according to the company.
  • The company stated that Cespira's HPDI technology is operating in more than 12,000 trucks worldwide and reported revenue of $27.1 million in the second quarter of 2026, a 125% increase from the same period last year.
  • HPDI fuel systems can reduce greenhouse gas emissions by 20% and up to 100% using bioLNG, hydrogen and HVO, according to the company.

Strategic/Operational Context

The company stated that the new brand brings its 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.

"Aetherion represents both our origin and our future," said Dan Sceli, CEO, according to the company. "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."

According to the company, Cespira is progressing toward profitability and self-sufficiency, reflecting accelerating fleet adoption and expanding geographic reach. The company stated that HPDI can expand through additional OEM adoption, CNG and RNG applications in North America, and hydrogen-fueled solutions, which it said broaden the addressable market and create demand for complementary high-pressure gaseous fuels storage and supply solutions within Aetherion's product portfolio.
