HPQ Silicon Signs Cell Evaluation Agreement With Aptera Motors for ENDURA+ Battery Cells

HPQ Silicon Signs Cell Evaluation Agreement with Aptera Motors for HPQ ENDURA+ High-Capacity Battery Cells

MONTREAL, Canada — HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: 8PY1), a technology company specializing in advanced materials innovation and the development of next-generation processes, is pleased to announce that HPQ Silicon, through its HPQ ENDURA+ battery initiative, together with its French technology partner Novacium SAS (“Novacium”), has signed a Cell Evaluation and Confidentiality Agreement with Aptera Motors Corp. (“Aptera”) (NASDAQ: SEV), a Nasdaq-listed U.S. solar mobility company advancing ultra-efficient transportation.

Under the agreement, Aptera will evaluate HPQ ENDURA+ high-capacity 21700 lithium-ion cells based on Novacium’s silicon-based anode materials and related cell technology. The evaluation will include laboratory testing.

The agreement represents an important step in HPQ’s North American battery commercialization strategy, moving HPQ ENDURA+ cells from technology development and internal validation into application-level evaluation.

Advancing HPQ ENDURA+ Toward Commercial Applications

Aptera is developing a solar electric vehicle designed around ultra-high efficiency, aerodynamics and integrated solar generation. The company has recently reported several milestones, including receiving an EPA Certificate of Conformity for its 2026 Launch Edition and announcing a manufacturing partnership with Launch Design.

For HPQ, the evaluation provides an opportunity for ENDURA+ cells to be assessed in an application where energy density and overall system efficiency are important engineering considerations.

Bernard Tourillon, President and CEO of HPQ Silicon, said:

This agreement represents exactly the kind of progression we have been working toward with HPQ ENDURA+,

“We have focused on moving our technology from advanced materials to high-performance cells, and ultimately into application-level evaluation, where its performance can be assessed in an EV application. We are excited to begin this process and see where the results may lead.”

From Cell Development to External Evaluation

Novacium has been advancing silicon-based anode materials and related cell technologies designed to increase the energy-storage capabilities of conventional lithium-ion battery formats. HPQ holds applicable commercial rights relating to Novacium technology in North America and participates in the commercial and industrial follow-up of potential future deployment.

Jed Kraiem, Chief Operating Officer of Novacium SAS, said:

Moving into evaluation with Aptera is an important next step for our cell technology,

“Our development work has been focused on translating the performance of our silicon-based materials into practical, high-capacity cells. Having those cells evaluated provides valuable application-level feedback, and we look forward to supporting Aptera’s technical team throughout the process.”

The evaluation also marks another step in HPQ’s strategy of building a North American commercialization pathway for HPQ ENDURA+, advancing from technical development into application-level evaluation as a first step toward validation for EV applications.

The initial evaluation does not constitute a commercial supply commitment. If the results support continued discussions, the parties may separately consider subsequent technical, qualification and commercial steps.
