Westport Fuel Systems Becomes Aetherion Technologies, Ticker AETR From October 23

Westport Fuel Systems Inc. has changed its name to Aetherion Technologies Inc., the company said on October 15, 2026, and expects its common shares to trade under the ticker AETR on the Toronto Stock Exchange and Nasdaq on or about October 23, 2026. The GlobeNewswire announcement said trading continues under WPRT until then, subject to final exchange approvals.

What The Aetherion Name Covers

Aetherion Technologies is a Vancouver-based clean-fuel technology company that develops HPDI hydrogen and natural gas fuel systems for heavy-duty trucks through the Cespira joint venture with Volvo Group, and high-pressure fuel components for OEM customers globally. The new name draws on the Greek roots aithēr, for the clean air of the upper sky, and ion, for motion or energy.

Dan Sceli, the chief executive, tied the identity to the company's founding work. "Aetherion represents both our origin and our future," he said. The company said the change has no impact on operations, ownership or commitments to customers, partners, employees and shareholders, and that shareholders need take no action because existing share certificates continue to represent shares of the renamed company.

Cespira Revenue And HPDI Reach

According to akta.pro company records, Cespira, the joint venture between Westport Fuel Systems and Volvo Group, signed a development agreement in June 2026 to finalize integration and commercialization of HPDI hydrogen fuel system technology for Volvo's 13-litre hydrogen-powered engine platform, with a European commercial launch targeted before 2030. The same records show Westport closed a US$10 million registered direct offering and concurrent private placement in June 2026, selling 1,600,000 common shares and 3,254,369 pre-funded warrants at an effective price of US$2.06 per unit, with Craig-Hallum Capital Group as sole placement agent.

The company said Cespira's HPDI fuel systems operate in more than 12,000 trucks worldwide and can reduce greenhouse gas emissions by 20% and up to 100% using bioLNG, hydrogen and HVO. Cespira reported revenue of $27.1 million in the second quarter of 2026, a 125% increase from the same period last year.

Westport's Run-Up To The Renaming

In August 2026, Westport reported a net loss of $11.4 million for the second quarter of 2026, driven by a 78% decline in consolidated revenue following the end of its transitional service agreement with Cespira, according to FinancialContent Business Page. Stock Titan reported the same month that the 78% year-over-year revenue decline to $2.7 million was primarily due to the conclusion of that agreement. Also in August 2026, Law360 reported that the Federal Circuit upheld the Patent Trial and Appeal Board's decision to maintain claims in a pair of fuel injection patents owned by Westport Fuel Systems Canada Inc.

Aetherion's October Trading Date

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, subject to final exchange approvals. The company's CUSIP and ISIN numbers will change in connection with the name change.
