Aegis Critical Energy certifies PWR Flex 261Q for U.S. market entry

Fully certified, fire protection validated battery energy storage platform by Aurosi/SEETEL becomes the first fully integrated quantum random number generating - secured BESS now certified for the North American market. Vancouver, British Columbia--(Newsfile Corp. - June 18, 2026) - Aegis Critical Energy Defence Corp. (CSE: QESS) (OTCQB: QESSF) (FSE: JG6) ("Aegis" or the "Company") is pleased to announce that our product the PWR-Flex 261Q battery energy storage system ("BESS"), in partnership with Aurosi Precision Co., Ltd. ("Aurosi") and SEETEL New Energy (Taiwan) (7740.TW) ("SEETEL"), has successfully completed another product safety standard program for entry into the U.S. marketplace, including fire safety evaluations and supporting NFPA 855 documentation required for deployment across North America. The PWR-Flex 261Q is a fully integrated AC 261 kWh / 135 kW, liquid-cooled LFP (lithium iron phosphate) outdoor BESS with IP67 battery packs housed in an IP55 enclosure, inverter, chiller, and integrated aerosol fire-suppression and multi-detector safety system.

The system has undergone a comprehensive, third-party certification and engineering validation process, including evaluations to UL 9540, UL 9540A, UL 1973, UL 1741 SB, CSA C22.2 No. 107.1, Functional Safety, NFPA 68 and NFPA 69, providing the technical foundation to meet NFPA 855 installation requirements across commercial, industrial and critical-infrastructure applications in North America. In parallel with this certification milestone, Aegis is also pleased to confirm the successful installation and commissioning of three legacy systems by our partner GG Ventures of the Carolinas, LLC ("GG Ventures") for one of GG Ventures' Fortune 500 clients. First Quantum-Secured BESS Now Certified The PWR-Flex 261Q incorporates an embedded quantum-secured cybersecurity architecture, integrating hardware-based Quantum Random Number Generation (QRNG) Quantum eMotion Corp's., (NYSE American: QNC) (TSXV: QNC) (FSE: 34Q0) ("QNC") to provide true quantum-grade entropy for cryptographic keys and signing of commands, telemetry, and firmware updates.

The PWR Flex 261Q is delivering one of only fully integrated commercial BESS platforms with built-in quantum-safe protection for data and control systems. The system is designed for mission-critical and regulated environments including utilities, telecommunications, defence, mining, industrial facilities, remote communities, marine applications and AI/data-center infrastructure. "This certification program is a turning point for Aegis," said Ramtin Rasoulinezhad, Ph.D., Chief Executive Officer of Aegis Critical Energy Defence Corp. "With PWR-Flex 261Q, we now have a fully certified, fire-validated and quantum-secured BESS platform that can be sold into the U.S. market with the documentation and safety credentials that utilities, industrial operators and regulators demand." "The NFPA 855 report and the full UL / CSA certification package remove a key barrier to entry and enable our sales channels to move from pilot discussions to revenue-generating projects across North America.

At the same time, our first installation of three systems in Indiana with GG Ventures and a Fortune 500 client proves that blue-chip customers are already willing to adopt BESS into secure infrastructure. We see this as a powerful early reference for Aegis as the grid, defence, and data-center sectors begin to treat cyber-resilient power as non-optional," added Dr. Rasoulinezhad.
