SEALSQ Corp to Lead EeroQ’s Upcoming Priced Financing Round

SEALSQ Corp said it made an additional investment in EeroQ and agreed to serve as lead investor in EeroQ’s upcoming priced financing round. The move followed ongoing technology cooperation and focused on continued work toward an integrated quantum security stack.

The company linked the expanded commitment to prior investments made in December 2025 and February 2026, and it said the funding used its Quantum Fund, an internal strategic investment initiative with a dedicated cash allocation. SEALSQ characterized the overall effort as part of its Quantum Made in USA strategy.

SEALSQ and EeroQ said their cooperation targeted an integrated Quantum Security Vertical Stack to be demonstrated at SEALSQ’s Quantum Center of Excellence in Geneva, subject to regulatory approval. The Proof of Concept would combine SEALSQ’s secure semiconductor hardware, post-quantum cryptography, and PKI services with EeroQ’s helium-based quantum processor architecture, aiming for end-to-end integration of classical, post-quantum, and quantum processing within a single trusted environment.

Under the new investment agreement, SEALSQ subscribed to an additional investment and committed to anchor EeroQ’s next priced financing round while supporting participation from additional strategic and institutional co-investors aligned with EeroQ’s U.S.-sovereign quantum roadmap. Carlos Moreira, Founder and CEO of SEALSQ, said, “Our decision to make a further investment in EeroQ, and to lead their next financing round, reflects both the strong progress of our ongoing technology cooperation and our deep conviction in the EeroQ team and platform.” Nick Farina, Co-Founder and CEO of EeroQ, said, “SEALSQ’s decision to deepen its commitment through an additional investment and to lead our upcoming financing round is a powerful endorsement of EeroQ’s technology and long-term vision.”

SEALSQ said the companies’ Proof of Concept planning and related commitments remained subject to regulatory approval and future financing round activity.
