Sealsq Signs LOI to Acquire 100% Equity of Miraex

Sealsq (LAES), a subsidiary of WISeKey International (WKEY), announced that it has signed a letter of intent to acquire 100% of the equity interest of Miraex, a developer of photonics-based quantum interconnect solutions that bridge quantum processors and quantum networks. The LOI provides for a 60-day exclusivity period to conduct confirmatory due diligence and negotiate definitive transaction documents. The transaction is expected to be finalized by the end of June 2026. The transaction would be carried out using the SEALSQ Quantum Fund. "Miraex represents exactly the kind of foundational quantum asset we have been seeking to complete our Quantum Vertical Stack," said Carlos Moreira, CEO. "Their photonics-based quantum interconnect solutions are not just complementary to our roadmap, they form a critical interconnect layer linking our quantum computing, quantum networking, and post-quantum cryptography capabilities into a more coherent architecture. Furthermore, the alignment with our QSOC initiative is compelling. Once the acquisition is completed, the integration of Miraex's technology is expected to accelerate our vision of extending quantum-secure infrastructure across terrestrial and space-based environments, strengthening the resilience and performance of our end-to-end platform."
