LONDON, Ontario, Sept. 01, 2026 (GLOBE NEWSWIRE) -- Aduro Clean Technologies Inc. (“Aduro” or the “Company”) (Nasdaq: ADUR) (TSX: ACT) (FSE: 9D5), a clean technology company using the power of chemistry to transform lower value feedstocks, like waste plastics, heavy bitumen, and renewable oils, into resources for the 21^st century, has filed its audited consolidated financial results for the year ended May 31, 2026, and is pleased to provide the following highlights. Unless otherwise indicated, all financial information in this press release is reported in Canadian dollars.

“Fiscal 2026 marked an important transition in Aduro’s development,” said Ofer Vicus, Chief Executive Officer of Aduro. “We moved the Next Generation Process (“NGP”) Pilot Plant from construction and commissioning into structured operating campaigns, while advancing the First-of-a-Kind (“FOAK”) Program at Chemelot and establishing clearer commercial pathways through offtake, licensing and downstream validation. These workstreams are increasingly connected: pilot operations are generating the data required to refine process conditions and equipment choices, while engagement with commercial and engineering organizations is helping define product requirements, project configuration and potential market pathways.”

“Subsequent to year-end, the latest NGP operating campaign demonstrated steady-state operation and strong liquid hydrocarbon recovery, while additional programs with AstroTurf and ECOCE expanded our work on complex plastic waste streams. We also advanced the paraffinic crude program into continuous-flow development. Together, these activities reflect a disciplined, data-driven approach to building technical confidence and preparing Aduro for the next stage of scale-up.”

“Fiscal 2026 was a year of deliberate investment in pilot plant operations, engineering, technical personnel and project development,” said Mena Beshay, Chief Financial Officer of Aduro. “We allocated capital to these priorities while strengthening the Company’s access to capital and broadening our capital-markets presence through our listing on the Toronto Stock Exchange. We maintained financial discipline throughout the year, closing fiscal 2026 with a cash position of $38.3 million. Subsequent to year end, Aduro received approximately $31 million in gross proceeds from a U.S. public offering and a non-brokered private placement further strengthening the balance sheet and increasing the resources available to support FOAK design, engineering and construction, ongoing research and development, and working capital. As we enter fiscal 2027, our focus remains on disciplined deployment of capital against defined technical and project milestones.”

NGP Pilot Plant Campaign Progress
In June 2026, Aduro reported results from an NGP Pilot Plant campaign conducted under its 24-hour, four-day operating model. Excluding startup and shutdown, the plant operated continuously for 47 hours using polypropylene recovered from waste plastics.

Steady-state conditions were achieved after approximately 12 hours and maintained for a further 35 hours. During the steady-state period, liquid hydrocarbon recovery represented approximately 86% of the mass of polypropylene fed to the reactor. Approximately 85% of the recovered liquid consisted of hydrocarbons with carbon numbers of C20 and below.

The campaign also demonstrated that steady-state conditions could be re-established within approximately two hours following intentional changes to operating conditions. The data are being used to refine operating parameters, support planning for longer-duration campaigns and inform the design basis for the FOAK Plant.

Strengthened Capital Position with Successful U.S. Public Offering and Non-Brokered Private Placement
In June 2026, Aduro completed an underwritten U.S. public offering of 1,028,645 common shares at US$15.20 per share, generating gross proceeds of approximately US$15.64 million. Proceeds are intended to support the design, engineering and construction of the FOAK Plant, ongoing research and development, general corporate purposes and working capital.

Additionally, the Company completed a non-brokered private placement, under the Listed Issuer Financing Exemption (the “LIFE Offering”), issuing 431,884 common shares at C$21.20 (US$15.20) per share for gross proceeds of approximately C$9.16 million (US$6.56 million). Proceeds from the LIFE Offering are intended to support technology development, commercialization activities, working capital and general corporate purposes.

Ortessa MOU Advances FOAK Plant Feedstock Logistics
In June 2026, Aduro Clean Technologies Europe B.V. signed a non-binding Memorandum of Understanding with Ortessa Groep B.V., a Dutch group of waste-management companies, to evaluate development of a feedstock logistics centre supporting the FOAK Plant at Chemelot.

The parties intend to evaluate the identification and aggregation of suitable post-use plastic streams, feedstock preparation requirements, quality-control systems, documentation, inventory management, storage and transportation.

The collaboration is intended to support a reliable supply of suitable, specification-ready post-use feedstock for startup and operation of the FOAK Plant while preserving logistics capacity for potential future expansion of the broader FOAK Facility.

AstroTurf MOU Advances Synthetic-Turf Recycling Evaluation
In June 2026, Aduro and AstroTurf Corporation signed a Memorandum of Understanding to evaluate the application of HCT to end-of-life synthetic turf.

The collaboration is intended to examine how mechanical pretreatment and HCT conversion could support a technical and economic pathway for recovery of polyethylene and polypropylene fractions and their conversion into liquid hydrocarbons suitable for use as circular feedstock in existing petrochemical infrastructure.

The work is expected to consider field recovery, disassembly, de-infill, separation of non-target materials, preparation of the polyolefin-rich fraction and management of associated side streams. The engagement builds on previously disclosed laboratory testing of post-use synthetic-turf materials.

ECOCE Collaboration Advances to HCT Testing
In July 2026, Aduro and ECOCE, A.C. completed Phase 1 feedstock mapping and stream selection under their Mexico plastics collaboration. Selected post-consumer flexible and multilayer packaging streams are advancing to an HCT test campaign intended to evaluate conversion into liquid hydrocarbon products for downstream circular-plastics applications. The selected materials include flexible polyethylene, flexible polypropylene and multilayer packaging formats with varying structures and contamination profiles.

The next phase will begin with laboratory-scale HCT testing, with progression to the NGP Pilot Plant subject to the results of the initial evaluation. The objective is to evaluate whether HCT can provide a route to recover hydrocarbon value from flexible packaging streams that are not well suited to mechanical or physical recycling.

Paraffinic Crude Program Advances to Continuous-Flow Development
In July 2026, Aduro reported that it had secured yellow-wax and black-wax paraffinic crude feedstocks from multiple Uinta Basin sources in quantities sufficient to support longer-duration testing.

The Company completed the design, construction and testing of a dedicated lab-scale continuous-flow unit for the paraffinic crude program. The unit is distinct from the Company’s existing R2 systems and provides additional capacity for sustained testing as the program advances through technology demonstration toward process development and optimization. Aduro also expanded its London, Ontario facility by approximately 4,600 square feet and consolidated operating activities and equipment previously located in Sarnia, Ontario.

The current program is intended to establish an operating envelope and evaluate conversion, yield, product characteristics, stability and fouling potential across multiple paraffinic crude feedstocks. The results will help determine whether the program should advance into Process Development and Optimization under extended continuous-flow operation.

Saipem Selected for FOAK Engineering and Procurement Support
In August 2026, Aduro selected Saipem S.p.A. (“Saipem”) to provide Early Works engineering and procurement support for the planned FOAK Plant at Chemelot. The initial scope includes review of the Process Design Package, optimization of critical equipment packages, preliminary utility integration and refinement of capital cost estimates, incorporating operating data from the NGP Pilot Plant.

Following year-end, Aduro participated in AMI Chemical Recycling Europe, Future of Advanced Recycling North America, the Canadian Climate Investor Conference and the ROTH London Conference, and subsequently participated in the Canaccord Genuity Annual Growth Conference 2026.

These activities included technical presentations addressing product quality, feedstock flexibility, downstream integration and the practical requirements for industrial deployment, as well as investor presentations, panel participation and institutional meetings following the Company’s listing on the TSX. Technical presentations also highlighted progress in advancing Hydrochemolytic™ Technology from pilot-scale validation toward FOAK industrial planning and commercialization.

Complete copies of the Company’s audited consolidated financial statements and Management’s Discussion and Analysis for the year ended May 31, 2026, are available under the Company’s profile on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov.

Note:
(1) Non-GAAP measure. Earnings before interest, taxes, depreciation, and amortization ("EBITDA") and Adjusted EBITDA should not be construed as alternatives to net income/loss determined in accordance with IFRS. EBITDA and Adjusted EBITDA do not have any standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. The Company defines EBITDA as earnings before interest, taxes, and amortization. Adjusted EBITDA is defined as EBITDA before stock-based compensation, change in fair value of derivative financial liability, and acquisition related expenses. The Company believes that EBITDA and Adjusted EBITDA are meaningful financial metrics for investors as it adjusts income to reflect amounts which the Company can use to fund working capital requirements and fund future growth initiatives.

Non-IFRS measures
This news release presents information about EBITDA and Adjusted EBITDA, both of which are non-IFRS financial measures, to provide supplementary information about operating performance. Aduro defines EBITDA as net income or loss before interest, income taxes, depreciation, and amortization. Adjusted EBITDA removes non-cash share-based compensation and non-cash change in fair value of derivative financial liability from EBITDA. The Company believes that EBITDA and Adjusted EBITDA is a meaningful financial metric for investors as it adjusts income to reflect amounts which the Company can use to fund working capital requirements and fund future growth initiatives. EBITDA and Adjusted EBITDA are not intended as a substitute for IFRS measures. A limitation of utilizing these non-IFRS measures is that the IFRS accounting effects of the adjustments do in fact reflect the underlying financial results of Aduro's business and these effects should not be ignored in evaluating and analyzing Aduro's financial results. Therefore, management believes that Aduro's IFRS measures of net loss and the same respective non-IFRS measure should be considered together. Non-IFRS measures do not have any standardized meaning prescribed by IFRS and are therefore unlikely to be comparable to similar measures presented by other companies.
