~ Strong demand for LNG HPDI™ trucks continues to drive revenue growth for Cespira™ ~

VANCOUVER, British Columbia, Nov. 12, 2026 (GLOBE NEWSWIRE) -- Aetherion Technologies Inc. (“Aetherion") (TSX:AETR / Nasdaq:AETR) (previously, Westport Fuel Systems Inc.) today reported financial results for the third quarter ended September 30, 2026, and provided an update on operations. All figures are in U.S. dollars unless otherwise stated.

“Our transition to Aetherion Technologies reflects a renewed focus on the opportunities where our technology and expertise can create the greatest value: practical, scalable and cost-effective solutions for heavy-duty transportation. We are aligning our portfolio and resources around that focus, directing our specialized technical and commercial capabilities to advance solutions for these sectors starting with our high-pressure CNG solution to help open up the North American market for CNG HPDI in heavy-duty trucking.

Building on the growth trend that we saw in the first two quarters of 2026, Cespira delivered product revenue growth of 85% in Q3, as compared to the same quarter last year.  There clearly is increasing interest amongst commercial fleets globally, and particularly in Europe,  reinforcing the commercial momentum behind Cespira's HPDI fuel system.  To address this growing demand in 2027, Cespira is investing in anticipation of this growth, with investment timing and scale aligned with customer requirements and fleet demands.

The opportunities ahead extend across fuels and markets. Cespira's HPDI™ 3.0 fuel system is scheduled to begin production in Q4 2026, with the first equipped vehicles expected on the road in early 2027. Alongside Cespira's next-generation platform, Aetherion has advanced its proprietary high-pressure CNG and renewable natural gas systems and solutions for North America. This solution is flexible enough to accommodate hydrogen and hydrogen / methane blended-fuel systems. Together, this system can expand market penetration for HPDI powered trucks and protect for future fuel availability while preserving the performance fleets require, supporting affordable emissions reductions, addressing energy security needs and reducing overall operational costs.

Strengthening our financial position remains a core priority. Our equity facility of up to $25 million, subject to certain limitation, provides additional financing flexibility. Our focus is on aligning investment with execution—supporting Cespira’s path toward self-funding and progressing our North American CNG solution as we build a more focused business for long-term growth.”

Dan Sceli, Chief Executive Officer 

Third Quarter 2026 Highlights 

• Revenues for the third quarter of 2026 increased by 60% to $2.6 million compared to $1.6 million in the same quarter last year.  In Q3 2025, we were moving the manufacturing into China and Cambridge, Ontario from its previous location in Italy.
  
  
• Cespira delivered strong financial performance, driven by significant growth in  product and aftermarket revenue. For the third quarter of 2026, revenue increased by $8.9 million or 46% compared to the prior year quarter. Cespira reduced its net loss by $5.7 million, continuing to reduce its reliance on funding from its partners. Aetherion reduced its capital contributions to Cespira in the quarter from $11.0 million to $2.8 million. The improvement in Cespira's financial performance was a result of higher sales volumes driven by increasing market acceptance and confidence in the product and OEM interest in HPDI technology, and favorable diesel to natural gas and biogas fuel economics, supported by continued improvement of supply chain execution as the business prepares for the launch of HPDI 3.0.
  
  
• Significantly improved net loss from continuing operations to $3.0 million for the quarter compared to a net loss from continuing operations of $10.4 million for the same quarter last year.  The reduction in the net loss from continuing operations is due to higher revenue, lower operating expenses, improved Cespira financial performance, and a $2.2 million gain on warrant liabilities remeasurement.
  
  
• Adjusted EBITDA¹ of negative $4.8 million compared to negative $6.3 million for the same period in 2025.  The decrease in negative adjusted EBITDA was primarily driven by lower operating losses, and a decrease in the loss from investments accounted for by the equity method. Included in the prior year quarter's adjusted EBITDA was our discontinued operations' performance, which included an operating profit of $1.8 million for the three months ended September 30, 2025.
  
  
• Cash and cash equivalents were $14.5 million for the third quarter of 2026. Cash used in operating activities from continuing operations was $5.0 million for the quarter, primarily driven by operating losses in the quarter and changes in working capital. Cash used in investing activities from continuing operations was primarily driven by capital contributions to Cespira of $2.8 million for the quarter. Cash used in financing activities from continuing operations were primarily driven by the debt repayment of $1.0 million in the quarter.  Long term debt, including the current portion, was fully repaid in the quarter.

Segment Information

High-Pressure Controls

Revenue for the three and nine months ended September 30, 2026 was $2.6 million and $7.6 million, respectively, compared with $1.6 million and $6.4 million for the three and nine months ended September 30, 2025.  The increase in revenue was primarily driven by higher volume of sales in the quarter compared to prior year, which was impacted by the transition of operations to the Company's manufacturing facilities in China and Cambridge, Ontario. As production and shipment levels normalized, the Company achieved higher shipment volumes during the current quarter, resulting in increased sales.

Gross profit was $0.1 million or 4% of revenue, for the three months ended September 30, 2026 compared to $0.5 million or 29% of revenue, for the three months ended September 30, 2025.  The decrease in gross profit margin was primarily attributable to the absence of a non-recurring, high-margin engineering services revenue recognized in the prior year period. We anticipate that as the manufacturing plants in Canada and China continue to work on localizing supply chain and improving their manufacturing processes and output, its gross profit and margin will benefit.

Heavy-Duty OEM

The segment's transitional service agreement with Cespira ended in Q2 2025 and, as a result, the segment did not have any sales activity in the quarter.

Selected Cespira Statements of Operations Data

We account for Cespira using the equity method of accounting. However, due to its significance to our long-term strategy and operating results, we disclose selected Cespira financial information in our interim financial statements for the three and nine months ended September 30, 2026.

The following table sets forth a summary of the financial results of Cespira for the three and nine months ended September 30, 2026.

_{⁽¹⁾ Gross margin are non-GAAP measures. Please refer to GAAP and NON-GAAP FINANCIAL MEASURES for the reconciliation to equivalent GAAP measures and limitations on the use of such measures.}

Product Revenue for the three and nine months ended September 30, 2026 was $20.7 million and $54.8 million compared to $11.2 million and $29.6 million for the three and nine months ended September 30, 2025. The increase in revenue of 85% in the current quarter was primarily driven by significantly higher volumes of systems sold compared to the prior year quarter. The year to date revenue growth was primarily driven by significantly higher volumes of systems sold in each of the first three quarters of 2026 compared to the corresponding prior year periods. Cespira's growth is influenced by the resilient favorable price differential between diesel and natural gas and government regulation support in markets like Europe. Growth was also supported by increasing industry recognition of HPDI technology as a commercially viable low emissions solution for heavy-duty transportation.

Aftermarket Revenue for the three and nine months ended September 30, 2026 was $4.9 million and $14.7 million compared to $3.6 million and $9.3 million for the three and nine months ended September 30, 2025. The increase in aftermarket revenue is primarily driven by an increase in sales volumes.

Service Revenue for the three and nine months ended September 30, 2026 was $2.7 million and $8.1 million compared to $4.6 million and $9.2 million for the three and nine months ended September 30, 2025. The decrease in service revenue for the three and nine month periods was primarily attributable to the timing of project milestone achievements, with higher milestone revenue recognized in the prior-year periods. Service revenue allocated to project milestones are weighted differently across the phases of an engineering service revenue project. One of Cespira's significant long-term engineering service revenue projects is expected to complete in Q4 2026 in advance of the anticipated launch of their HPDI 3.0  product.

Gross profit was $3.7 million and $9.1 million for the three and nine months ended September 30, 2026 compared to gross loss of $1.0 million and $2.4 million for the three and nine months ended September 30, 2025. The increase in gross profit was primarily driven by the increase in volumes of systems and aftermarket products sold along with cost reductions in materials and improvements in labor efficiency.

Cespira had an operating loss of $0.5 million and $5.2 million for the three and nine months ended September 30, 2026 compared to $5.9 million and $19.8 million for the three and nine months ended September 30, 2025. Cespira significantly reduced its operating loss compared to the prior year quarter by meaningfully increasing its product revenue, gross margin and lowering its cost base as it continues to grow and scale the business. The improvement also reflects management's focus on growing volumes, enabling supply chain execution and maintaining a tightly controlled cost environment as it prepares for the launch of HPDI 3.0.

Cespira sees continued growth opportunities in the LNG heavy-duty market, as favorable fuel-price differentials relative to diesel, concerns around energy availability and security, and tightening emissions regulations strengthen the case for fleet adoption of HPDI technology. To capture this opportunity, Cespira is evaluating capacity investments in 2027, scaled to align to anticipated demand. These investments are expected to be self-funded through Cespira's operations. Combined with improving operating leverage and disciplined cost management, this approach positions Cespira to translate higher demand into stronger financial performance.

Liquidity and Going Concern

As at September 30, 2026, we had cash and cash equivalents of $14.5 million and no long-term debt. 

Based on our projected capital expenditures and operating requirements under our current business plan, we are projecting that our cash and cash equivalents will not be sufficient to fund our operations through the next twelve months from the date of the issuance of our Q3 2026 MD&A. These conditions raise substantial doubt about Aetherion's ability to continue as a going concern within one year after the date that our Q3 2026 MD&A is issued. 

Although the Company was able to raise equity financing in the prior quarters, management continues to evaluate  different options to improve Aetherion's liquidity position, including  access to the Committed Equity Facility, raising funds from the public markets,  borrowing debt or other financing alternatives. These plans are not final and are subject to market and other conditions not within our control. As such, there can be no assurances that Aetherion will be successful in obtaining sufficient funding. Accordingly, we concluded under the accounting standards that these plans do not alleviate the substantial doubt about Aetherion's ability to continue as a going concern.

GAAP and NON-GAAP FINANCIAL MEASURES

Our financial statements are prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"). These U.S. GAAP financial statements include non-cash charges and other charges and benefits that may be unusual or infrequent in nature or that we believe may make comparisons to our prior or future performance difficult. In addition to conventional measures prepared in accordance with U.S. GAAP, Aetherion and certain investors use EBITDA and Adjusted EBITDA as an indicator of our ability to generate liquidity by producing operating cash flow to fund working capital needs, service debt obligations and fund capital expenditures. Management also uses these non-GAAP measures in its review and evaluation of the financial performance of Aetherion. EBITDA is also frequently used by investors and analysts for valuation purposes whereby EBITDA is multiplied by a factor or "EBITDA multiple" that is based on an observed or inferred relationship between EBITDA and market values to determine the approximate total enterprise value of a company. We believe that these non-GAAP financial measures also provide additional insight to investors and securities analysts as supplemental information to our U.S. GAAP results and as a basis to compare our financial performance period-over-period and to compare our financial performance with that of other companies. We believe that these non-GAAP financial measures facilitate comparisons of our core operating results from period to period and to other companies by, in the case of EBITDA, removing the effects of our capital structure (net interest income on cash deposits, interest expense on outstanding debt and debt facilities), asset base (depreciation and amortization) and tax consequences. Adjusted EBITDA provides this same indicator of Aetherion's EBITDA from continuing operations and removing such effects of our capital structure, asset base and tax consequences, but additionally excludes any unrealized foreign exchange gains or losses, stock-based compensation charges and other one-time impairments and costs which are not expected to be repeated in order to provide greater insight into the cash flow being produced from our operating business, without the influence of extraneous events.

Segment Information

EBITDA and Adjusted EBITDA are intended to provide additional information to investors and analysts and do not have any standardized definition under U.S. GAAP, and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with U.S. GAAP. EBITDA and Adjusted EBITDA exclude the impact of cash costs of financing activities and taxes, and the effects of changes in operating working capital balances, and therefore are not necessarily indicative of operating profit or cash flow from operations as determined under U.S. GAAP. Other companies may calculate EBITDA and Adjusted EBITDA differently.

Segment earnings or losses before income taxes, interest, depreciation, and amortization ("Segment EBITDA") is the measure of segment profitability used by the Company. The accounting policies of our reportable segments are the same as those applied in our consolidated financial statements. Management prepared the financial results of the Company's reportable segments on basis that is consistent with the manner in which Management internally disaggregates financial information to assist in making internal operating decisions. Certain common costs and expenses, primarily corporate functions, among segments differently than we would for stand-alone financial information prepared in accordance with GAAP. These include certain costs and expenses of shared services, such as IT, human resources, legal, finance and supply chain management.  Segment EBITDA is not defined under U.S. GAAP and may not be comparable to similarly titled measures used by other companies and should not be considered a substitute for net earnings or other results reported in accordance with GAAP. Reconciliations of reportable segment information to consolidated statement of operations can be found in section "Non-GAAP Measure & Reconciliations" within this this press release.
