VANCOUVER, BC, December 18, 2025 -- BTQ Technologies Corp. ("BTQ" or the "Company"), a global quantum technology company focused on securing mission-critical networks, today announced a strategic investment in Keypair, a leading Korean full-stack security company trusted by major institutions across defense, energy, and financial services.

Under the terms of the investment and related collaboration, BTQ will co-own Keypair's existing and future post-quantum cryptography (PQC) related intellectual property and the companies will jointly develop next-generation hardware-based security technologies that are post-quantum-ready and infrastructure-grade.

Keypair's security technologies are deployed across Korea's most critical national infrastructure, including systems supporting LIG Nex1, Hanwha Systems, and Korea Electric Power Corporation (KEPCO), where Keypair has supplied millions of secure-element-based security chips supporting KEPCO's nationwide Advanced Metering Infrastructure program.

"Post-quantum security is moving from theory to deployment, and the winners will be the companies that can deliver certified, hardware-rooted security at national scale," said Olivier Roussy Newton, Chief Executive Officer of BTQ Technologies. "Keypair has built deep trust inside Korea's most demanding environments. This strategic investment strengthens BTQ's position as a long-term leader in post-quantum, infrastructure-grade security and accelerates our ability to support mission-critical systems as global standards and regulations evolve."

"Keypair has always focused on commercial, long-lived security systems that operate in the real world, not just pilots," said Dr. Jung-Youp Lee, Co-Founder, Co-CEO and CTO of Keypair. "Partnering with BTQ advances our post-quantum roadmap and expands the scope of what we can deliver in next-generation hardware security for critical infrastructure and institutional platforms."

Strategic significance for BTQ

• 1. Secures strategic post-quantum cryptography intellectual property and accelerates co-development across hardware-based security technologies designed for quantum-era threats.
• 2. Expands BTQ's footprint in Korea through a partner with proven, long-term deployments across national infrastructure, defense supply chains, and institutional environments.
• 3. Strengthens BTQ's infrastructure-first positioning by aligning with systems that are already deployed at scale and built for long service lifecycles.

This strategic investment further strengthens BTQ's commercial pathway in Korea by enabling tighter integration of BTQ's post-quantum cryptography and hardware-rooted security capabilities into enterprise and government deployments pursued through BTQ's relationships with Finger and Danal, and its broader engagement through QUINSA. By pairing Keypair's proven, at-scale secure element and critical infrastructure footprint with BTQ's quantum-safe security roadmap, BTQ is positioned to accelerate real-world implementations across payments, identity, and regulated institutional systems, while supporting standardized, interoperable post-quantum security architectures that can be rolled out across partner ecosystems.
