French Army Technical Section (STAT) Awards Novacium a Contract to Supply High-Capacity Prototype Batteries for Tactical Radios

Novacium was selected for its high-capacity GEN 3 and GEN 4 cylindrical cells, designed for high-capacity battery applications. The contract was awarded at the end of June 2026

MONTREAL, Canada — HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: 8PY1), is pleased to inform its shareholders that its strategic partner, NOVACIUM SAS, a French deep-tech company specializing in green engineering of materials for energy applications, has announced that the French Army Technical Section (“STAT”) awarded it a contract [1] at the end of June 2026 for the development and supply of high-capacity prototype batteries to be evaluated in tactical radios. For procedural reasons, the award could not be announced prior to today.

From Initial Evaluation to Contract Award: More Than Eighteen Months of Technical Collaboration

In August 2024, STAT, the French Army organization responsible for evaluating and qualifying equipment for land forces, contacted Novacium after reviewing published results from cells developed using its silicon-based anode material. The organization sought to evaluate the possibility of integrating Novacium’s cells into the batteries used in its tactical radios.

Following six months of internal development, Novacium’s teams developed two battery prototypes, which were provided to STAT in April 2025. The initial results were conclusive: with comparable form factors and interfaces, energy capacity increased by 23% compared with the reference battery.

Building on these results, in September 2025 Novacium met with France’s Directorate General of Armaments (DGA), Defence Innovation Agency (AID), and STAT to propose a work program to develop very high-capacity prototype batteries.

Several months of discussions followed to refine the program around an ambitious objective: significantly increasing, or potentially doubling, the energy capacity of tactical radio batteries without modifying existing connectors, chargers, or interfaces. This work resulted in a contract award to Novacium at the end of June 2026.

Selection Based on the Performance of Novacium’s High-Capacity Cells

Novacium was selected based on the performance of its very high-capacity GEN 3 and GEN 4 cylindrical cells, designed for high-capacity battery applications. This distinctive energy density made it possible to propose a solution capable of meeting STAT’s objective: significantly increasing the operating time of tactical radios without disrupting existing charging infrastructure, procedures or the logistics chain.

The contract provides for delivery in successive batches, structured around operational field feedback (RETEX). The first batch of prototypes will undergo an evaluation campaign under operational conditions, after which STAT and Novacium will jointly prepare a detailed RETEX. Lessons learned from this evaluation will guide design adjustments before production of a second batch that will better reflect a series-production configuration.

“The award of this contract by STAT represents an important recognition of Novacium’s expertise in designing high-performance cells and batteries for demanding environments. We were selected because our GEN 3 and GEN 4 cells offer a distinctive energy density capable of meeting particularly demanding specifications. This program illustrates our strategy: applying our materials and battery expertise to critical defence and security applications,” said Dr. Jed Kraiem, Ph.D., Chief Operating Officer of Novacium.

Potential Applications with Other Allied Forces

The expertise deployed under this program (high-capacity cell integration, battery management system adaptation and enclosure design) could be applied to other battery formats for tactical radios used by the armed forces of NATO member countries. A successful evaluation by STAT could serve as a technical reference to support this approach. However, each adaptation would remain subject to the relevant platform’s specific requirements, qualification testing, and separate procurement decisions.

“Novacium’s selection by the French Army’s technical organization responsible for equipment evaluation and qualification represents an important step in validating its expertise,” said Bernard Tourillon, President and CEO of HPQ Silicon Inc., which serves as President of Novacium. “If the evaluation phase confirms the expected performance, this program could become a relevant technical reference for presenting the solution to other allied forces with comparable requirements. For HPQ, every advance Novacium makes in the defence sector also strengthens the strategic value of our 36.8% interest in Novacium, as well as the potential to commercialize in North America the technologies covered by our licensing agreement.”

This contract is part of the continued development of Novacium’s activities in the defence and autonomous systems sectors. It follows the August 19, 2026, announcement of a first order for battery packs intended to power drones to be delivered to a French Army regiment through LN’INNOV.

Additional Information:

[1] A “marché,” in the context of French public procurement, refers to a paid contract entered between a public purchaser and an economic operator to meet a requirement for works, supplies or services in exchange for a price or equivalent consideration. In this case, the contract awarded to Novacium covers the development and supply, in successive batches, of prototype batteries intended for evaluation by STAT. The financial terms and quantities covered by the contract are subject to confidentiality obligations and are not disclosed.
