HPQ Receives First Industrial Shipments of HPQ ENDURA+ Batteries

With the first ENDURA+ batteries now in hand, HPQ prepares to distribute samples for field testing and advance toward full-scale commercialization

MONTREAL, Oct. 30, 2025 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ, OTCQB: HPQFF, FRA: O08), a technology company driving innovation in advanced materials and critical process development, announces that it has received its first industrial shipments of HPQ ENDURA+ lithium-ion battery cells from the manufacturer ^[1].

The shipment, which arrived at HPQ’s Montreal office late last week, includes both 18650 and 21700 cylindrical formats incorporating HPQ’s and Novacium ^[2] GEN3 silicon-based anode material.

These pre-commercial cells mark the transition from laboratory validation to real-world performance evaluation. HPQ will now begin distributing units to selected industry partners and institutional testers across mobility, energy storage, and defense sectors for independent field testing under various operating conditions.

STEP TOWARD MARKET VALIDATION

The receipt of these first HPQ ENDURA+ cells represents a critical milestone in HPQ’s path to commercialization. Built on the success of extensive lab trials conducted by Novacium throughout 2024 and 2025, the 18650 and 21700 cells have already demonstrated promising electrochemical stability, high energy density, and compatibility with existing lithium-ion production infrastructure.

Novacium continues to scale industrial manufacturing at its French facility, with production capacity now established for up to 1.5 million equivalent 18650-format cells annually. This gives us the flexibility to produce, based on demand, both 18650 and 21700 batteries.

“Receiving these first industrial batches is more than a logistical step—it’s the bridge between development and market validation,” said Bernard Tourillon, President and CEO of HPQ Silicon Inc. “We can now place HPQ ENDURA+ cells directly into the hands of end users and testing partners. This will allow us to confirm performance consistency across environments and gather the operational data we need ahead of full-scale commercialization.”

ADVANCING A NORTH AMERICAN BATTERY STRATEGY

Developed jointly with Novacium SAS, HPQ’s GEN3 silicon-anode technology is designed to enhance energy density and cycle life while remaining compatible with existing cell manufacturing infrastructure. This unique approach accelerates technology transfer and supports HPQ’s long-term vision: establishing localized, high-value battery material production in Canada to strengthen North American supply chains for advanced energy storage.

As testing proceeds and certification feedback is received, HPQ plans to update investors and partners on performance metrics, certification milestones, and forthcoming production schedules.
