Novacium, LN Innov' and Groupe Zekat to showcase a fully Integrated European Drone Propulsion Solution at Eurosatory 2026

• HPQ holds a 36.8% equity interest in Novacium SAS and an exclusive North American license to Novacium technologies for Canada, the United States, and Mexico.
  

MONTREAL, June 04, 2026 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ, OTCQB: HPQFF, FRA: O08), a technology company specializing in advanced materials and next-generation processes, today announced that its French technology partner, Novacium SAS ("Novacium"), will showcase a new Integrated Drone Propulsion System (IDPS) at Eurosatory 2026 alongside its partners LN Innov' and Groupe Zekat.

The three companies will exhibit together on a shared stand, presenting a complete European drone powertrain solution. The IDPS platform combines Novacium's advanced battery technologies, LN Innov's high-performance electric propulsion motors, and Groupe Zekat intelligent electronic speed controllers (ESCs).

The initiative was led by LN Innov', which has assembled this industrial ecosystem and acts as the system integrator for the propulsion package. The battery component of the system leverages Novacium's advanced silicon-enhanced lithium-ion battery technologies, designed to deliver higher energy density while remaining compatible with existing manufacturing infrastructure.

Designed and manufactured in France, the Integrated Drone Propulsion System offers an alternative to fragmented international supply chains by combining critical propulsion technologies from trusted European partners. The solution supports growing requirements for technological sovereignty, supply-chain security and operational performance.

"Eurosatory represents a unique opportunity for Novacium to present its technologies directly to organizations operating in some of the most demanding environments. As drone systems become increasingly important across defense, security, and industrial applications, end-users are seeking solutions that combine performance, reliability, and supply-chain resilience,” stated Dr. Jed Kraiem, Chief Operating Officer, Novacium. “Our participation allows us to showcase the Integrated Drone Propulsion System developed in collaboration with LN Inov and Groupe Zekat, while engaging directly with potential customers, industry partners, and institutional stakeholders. Beyond increasing awareness of our technologies, Eurosatory provides valuable insight into evolving operational requirements and helps guide the next stages of our development and commercialization efforts."

“Eurosatory brings together many of the organizations shaping the future of defense, security and autonomous systems," stated Bernard Tourillon, Chairman, President and CEO of HPQ Silicon Inc. "Through our strategic investment in Novacium and our exclusive North American licensing rights, HPQ sees this initiative as an opportunity to increase awareness of these technologies, engage with potential commercial partners and better understand evolving market requirements. These discussions may help inform future commercialization opportunities associated with our exclusive rights across Canada, the United States and Mexico."

The joint presentation at Eurosatory 2026 represents an important commercial showcase for the partners as they seek to position a European-developed propulsion ecosystem within rapidly expanding global drone markets.
