Quarterly Activities/Appendix 4C Cash Flow Report

• Strategic commercial leads generated by new Advisory Board
• Advancing PFAS destruction technology with high-voltage REM system
• Expanded license to apply Flash Joule Heating to PFAS-contaminated adsorbents

Environmental Clean Technologies Limited (ASX: ECT) presented its quarterly activity report and Appendix 4C for the period ended 31 March 2026. Key highlights include: 1) Completed the formation of an Advisory Board to provide technical and commercial guidance, with the group already delivering leads with targeted industrial partners. 2) Continued development of a high-voltage REM (Rapid Electrothermal Mineralisation) system to permanently destroy PFAS in soil, including demonstrating scalability and uniform heating to 1,000°C without the need for conductive additives. 3) Expanded the company's license agreement with Rice University to include the application of Flash Joule Heating (FJH) to PFAS-contaminated adsorbents like granular activated carbon (GAC), broadening the addressable market into water treatment. 4) Received a $556,698 R&D Tax Incentive rebate, further strengthening the cash position to support ongoing technology commercialization. The company also provided an outlook, noting the technical progress and expanded PFAS remediation capabilities as pivotal advancements that enhance the commercial outlook and opportunity to participate across the full PFAS destruction value chain.

The company's targeted R&D initiatives have delivered a step-change in technical capability, significantly advancing its understanding and ability to overcome key barriers to PFAS remediation, particularly within contaminated soils. The successful expansion of its PFAS remediation capabilities to include the destruction of PFAS on granular activated carbon (GAC) significantly broadens the company's addressable market and introduces a complementary pathway to commercialisation, particularly within water treatment and filtration systems. Collectively, the R&D progress and successful extension of the company's technology applications mark a pivotal advancement in establishing an integrated PFAS destruction platform.
