Aetherion Revenue Rises 60% in Third Quarter to $2.591 Million

Key Facts

Aetherion Technologies, formerly known as Westport Fuel Systems, reported results for the third quarter ended Sept. 30, 2026, with consolidated revenue of $2.591 million, up 60% from $1.617 million in the year-earlier period. The company’s announcement showed that the increase in consolidated revenue coincided with a reduction in its net loss from continuing operations to $2.990 million from $10.410 million a year earlier, a decline of 71%. The joint venture Cespira was the main source of business expansion, with revenue from its products rising 85% year over year. The results distinguish growth at the joint venture from Aetherion’s consolidated revenue, which remained at $2.591 million during the quarter. All amounts are in U.S. dollars unless otherwise noted.

The company said Cespira revenue increased $8.9 million, or 46%, from the third quarter of the previous year, while the venture’s net loss fell $5.7 million. Aetherion attributed product revenue growth to higher sales volumes, greater market acceptance and product confidence, as well as interest from original equipment manufacturers in HPDI technology. It also said favorable fuel economics for natural gas and biodiesel supported demand and supply chain execution improved. The 85% increase in product revenue reflects one aspect of the business’s expansion, while 46% growth in total Cespira revenue provides a broader picture of the venture’s quarterly performance. Aetherion, formerly Westport, owns a 55% stake in Cespira, while Volvo holds 45%; the venture focuses on developing and marketing HPDI technology for heavy-duty trucks and long-haul transportation.

At the parent-company level, Aetherion said the narrower loss from continuing operations was related to higher revenue, lower operating expenses and improved Cespira performance. It added that a $2.2 million gain from remeasurement of warranty obligations also contributed to the improvement. Adjusted loss before interest, taxes, depreciation and amortization was $4.843 million, compared with a loss of $6.313 million in the year-earlier quarter. The company linked the improvement in this measure to lower operating losses and losses from equity-method investments. By contrast, revenue for the first nine months of the year was $7.593 million, down 65% from $21.438 million in the same period of 2025, highlighting the difference between quarterly performance and the year-to-date total.

The company ended the quarter with $14.529 million in cash and cash equivalents, after using $5.039 million in operating activities for continuing operations and repaying $1 million of debt during the period. Aetherion said it has an equity financing facility of up to $25 million, subject to restrictions, providing additional financing flexibility. This comes against the backdrop of an earlier warning in the company’s annual report that cash available at the end of 2025 would not be sufficient to fund operations for the following twelve months, and that its financing plans did not eliminate substantial doubt about its ability to continue as a going concern. Cash and cash equivalents at the end of 2025 were about $27.2 million. The reported quarterly figures provide a picture of liquidity, cash use and debt repayment, alongside the financing tools the company cited.

On the product front, Aetherion said production of Cespira’s HPDI 3.0 liquefied natural gas system is scheduled to begin in the fourth quarter of 2026, with the first vehicles equipped with it expected on the road in early 2027. The timeline follows quarters of annual growth in venture revenue: in the second quarter, the company reported a 125% increase and a 298% improvement in gross profit, supported by higher customer orders for the HPDI system. In the first quarter, Cespira revenue rose 33%, with additional volumes delivered to a second original equipment manufacturer for a truck trial. Westport Fuel Systems changed its legal name to Aetherion Technologies on Oct. 14, 2026, and expected trading under the new name and symbol to begin around Oct. 23, pending final approvals. The company scheduled its results discussion call for Nov. 13, 2026, at 7:00 a.m. Pacific time, corresponding to 9:00 a.m. Eastern time.
