Vancouver, British Columbia--(Newsfile Corp. - June 2, 2026) - Aegis Critical Energy Defence Corp. (CSE: QESS) (OTCQB: QESSF) (FSE: JG6) ("Aegis" or the "Company"), together with its Indigenous majority-owned partner, Malahat Energy Systems Inc. ("Malahat"), is pleased to announce the completion of a comprehensive third-party certification and engineering validation package for the PWR-Flex 261Q energy storage platform. The milestone builds upon the Company's previously announced commercialization activities and further strengthens the platform's readiness for commercial, industrial, utility, telecommunications, mining, marine, Indigenous community, defence, remote, and critical infrastructure deployments throughout North America.

The PWR-Flex 261Q certification and engineering package, completed by CSA Group and independent engineering specialists and commissioned through the platform's manufacturing partners, includes UL 9540, UL 9540A, UL 1973, UL 1741 SB, CSA C22.2 No. 107.1, Functional Safety, NFPA 68, and NFPA 69 evaluations supporting commercial, industrial, utility, telecommunications, mining, marine, Indigenous community, defence, remote, and critical infrastructure applications.

The PWR-Flex 261Q is a fully integrated, plug and play 261 kWh / 135 kW outdoor Battery Energy Storage System ("BESS") combining Lithium Iron Phosphate ("LFP") battery technology, liquid-cooled thermal management, intelligent controls, integrated fire suppression, advanced monitoring systems, and optional quantum-secure control architecture within a compact factory-tested enclosure.

"The completion of this certification and engineering validation program represents an important milestone in our strategy to deliver secure, resilient, and commercially deployable energy storage solutions for critical infrastructure customers," said Ramtin Rasoulinezhad, Chief Executive Officer of Aegis Critical Energy Defence Corp.

"The PWR-Flex 261Q combines advanced energy storage technology, comprehensive third-party safety validation, intelligent controls, and optional quantum-secure communications architecture into a highly scalable platform suitable for a broad range of industrial, utility, and critical infrastructure applications."

Built for Critical Infrastructure

Engineered for demanding operating environments, the PWR-Flex 261Q utilizes liquid-cooled LFP battery technology and is designed to operate in temperatures ranging from -30°C to +50°C. The platform incorporates IP67 battery packs housed within an IP55 outdoor enclosure and includes integrated aerosol fire suppression, intelligent battery management, advanced monitoring systems, and flexible communications protocols suitable for deployment in commercial facilities, industrial operations, telecommunications networks, microgrids, remote energy systems, mining operations, marine applications, and critical infrastructure projects.

The PWR-Flex 261Q platform is available with Quantum-Secure Controller architecture utilising Quantum eMotion Corp's., (NYSE American: QNC) (TSXV: QNC) (FSE: 34Q0), hardware-based Quantum Random Number Generation ("QRNG") technology that enables cryptographic signing of commands, telemetry, and firmware updates using quantum-derived entropy, supporting advanced cybersecurity requirements for utilities, telecommunications networks, defence infrastructure, and other mission-critical applications. The integration of QRNG technology will strengthen security through enhanced cryptographic key generation and supporting secure communications across distributed energy infrastructure and critical energy systems.

Supporting the ToughBhoy Platform

The certified PWR-Flex 261Q platform also serves as the foundational energy-storage building block within the Company's ToughBhoy mobile energy platform. Designed for defence, Arctic, mining, remote operations, emergency response, and critical infrastructure applications, ToughBhoy utilizes the same certified 261 kWh LFP energy modules combined with ruggedized deployment configurations, −50 °C to +55 °C operating envelope, advanced controls, and optional quantum-secure communications architecture.
