WISeQey (WKEY) announced that its subsidiary WISeSat.Space completed its business combination with Columbus Acquisition, establishing a separately listed public company. The transaction closed on October 1, 2026, following approval by Columbus Acquisition shareholders on September 30. WISeSat.Space ordinary shares began trading on the Nasdaq Capital Market as SAIQ on October 2, 2026.
WISeSat.Space focuses on satellite communications secured against potential quantum-computing threats and Internet of Things connectivity, linking connected devices through satellite infrastructure. It has deployed satellites into orbit since 2024. Working within WISeQey’s technology ecosystem, including collaboration with sister company SEALSQ (LAES), WISeSat.Space aims to integrate hardware-based security, device authentication and post-quantum protection into its satellite communications architecture.

WISeSat.Space is a subsidiary of WISeQey and has deployed satellites into orbit since 2024. It aims to expand its space infrastructure and integrate hardware-based security, device authentication and post-quantum protection—security designed for threats from quantum computing—into satellite communications. This development involves collaboration with SEALSQ within the WISeQey technology ecosystem.
WISeQey (WKEY) completed WISeKey’s redomiciliation from Switzerland to the British Virgin Islands through a cross-border merger effective October 1, 2026. WISeKey merged into its wholly owned subsidiary WISeQey, the surviving company.
Existing WISeKey American Depositary Shares (ADSs) and Class B shares will trade on Nasdaq and SIX, respectively, through October 2. WISeQey ordinary shares are expected to begin trading as WQEY on the Nasdaq Global Market and SIX on October 5, with SIX as the primary listing. Each WISeKey ADS will be exchanged for one-half of one WISeQey ordinary share. Each WISeKey Class B share will be exchanged for one ordinary share, unless its holder elected to receive unlisted WISeQey Class B shares; that election provides ten WISeQey Class B shares for each WISeKey Class B share.
WISeKey (WKEY) reported approximately $11.4 million in unaudited first-half 2026 revenue, up approximately 116% from the same period in 2025.
Gross profit rose 192% to $5.5 million, with gross margin reaching approximately 48%. Operating loss widened to $40.9 million from $27.3 million, and net loss widened to $36.4 million from $22.3 million. Cash and restricted cash totaled approximately $495 million at June 30, with minimal debt. WISeKey reaffirmed expected FY 2026 revenue growth of 50% to 100%. SEALSQ's estimated commercial pipeline exceeds $225 million through 2029, subject to conversion risks.
Shareholders approved redomiciliation to the British Virgin Islands, expected October 1, with WISeQey shares expected to trade October 5. Proposed WISeSat and Quantisimo combinations remain conditional. Post-quantum product revenue is expected in Q4 2026; a proposed Jura semiconductor center carries indicative investment of CHF 40 million to CHF 60 million over six years.
SEALSQ (LAES) highlighted subsidiary IC’Alps’ custom chip design capabilities for implantable and connected medical devices following its DeviceMed buyer’s guide feature. IC’Alps, acquired by SEALSQ in August 2025, develops application-specific integrated circuits, or ASICs: chips tailored to individual products.
Featured in the DeviceMed Buyer’s Guide 2026–2027, the subsidiary has developed custom electronic solutions since 2018. Its ISO 13485-certified design and supply expertise serves applications including implantable cardiac devices, smart ultrasound probes and brain-computer interfaces.
WISeKey (WKEY) expects its merger into British Virgin Islands subsidiary WISeQey and its redomiciliation to take effect October 2, 2026. The cross-border merger depends on completion of registration procedures. WISeQey would survive, assuming WISeKey’s assets, rights, liabilities and obligations; WISeKey would cease to exist separately. Shareholders approved the merger and related agreement on September 9.
WISeQey ordinary shares are expected to begin trading under WQEY on the Nasdaq Global Market and SIX Swiss Exchange on or about October 5, with SIX as their primary listing. WISeKey expects October 2 to be the last trading day for its Nasdaq American depositary shares and SIX Class B shares. After delisting and cancellation, holders will receive WISeQey securities under previously communicated exchange ratios, elections and settlement procedures. The company does not expect its businesses or operations to change; WISeQey’s operational headquarters and effective management would remain in Switzerland.
WISeKey (WKEY) reported Class B share election results for its proposed merger into WISeQey, its renamed British Virgin Islands subsidiary.
WISeQey, formerly WISeKey International Corp., changed its name effective September 16, 2026, and will survive the merger. The election closed on September 23, 2026, at 14:00 CEST. Holders of 518 WISeKey Class B shares validly chose the WISeQey Class B option. Upon completion, WISeQey expects to issue 5,180 Class B shares for those elections, 4,176,654 ordinary shares for the remaining WISeKey Class B shares, including those represented by ADSs, and 1,819,060 Class F shares for outstanding WISeKey Class A shares.
Eligible holders could elect one ordinary share or ten Class B shares per WISeKey Class B share; the Class B option was subject to a cap and allocation rules. Holders without a timely, valid election default to the ordinary-share option. WISeKey shareholders approved the proposed merger on September 9, 2026. Closing remains subject to outstanding conditions and Swiss and BVI procedures; an effective date and trading start date have not been announced.
WISeKey (WKEY) and OISTE.ORG announced an expansion of their Quantum Root Key initiative into a post-quantum Root of Trust architecture for AI systems. The architecture is designed to give AI models and agents cryptographically verifiable identities linked to organizations, devices and authorized human operators. It uses NIST-standardized post-quantum algorithms, including ML-DSA and ML-KEM.
WISeKey says the architecture could help verify model integrity, agent authorization and signed AI actions. Its subsidiary SEALSQ (LAES) could extend the Root of Trust into secure elements and other semiconductor hardware. The announcement describes potential uses but gives no deployment date or commercial terms.
SEALSQ (LAES) announced a commercial expansion of VaultIC408 following FIPS 140-3 Level 3 validation issued August 5, 2026.
NIST Certificate No. 5463 covers VaultIC408 version 1.2.4 in its approved configuration and remains active through August 4, 2031. It does not validate other SEALSQ products or post-quantum algorithms. SEALSQ expects the validation to support expansion in government and other regulated markets.
Separately, the company targets a QS7001 V1 hardware evaluation report in October 2026 and a V2 full post-quantum hardware evaluation report in January 2027. Progress toward Common Criteria EAL5+ certification is planned for 2027, subject to certification-authority review and timelines.
SEALSQ (LAES) and parent WISeKey announced further expansion of the SEALSQ–WISeKey Quantum Highway™, an interconnected sovereign technology infrastructure linking capabilities across Switzerland, Spain, France, the United States, India and planned space-based assets.
The Quantum Highway is designed as a chain of trust from secure semiconductor and ASIC design through post-quantum security, Root of Trust and PKI, photonics, quantum computing and quantum-secure satellite communications. A planned Post-Quantum Semiconductor and Cybersecurity Center in the Canton of Jura, Switzerland, contemplates CHF 40–60 million of investment and approximately 150 qualified jobs within five years, and more than 250 longer term. The roadmap also contemplates the Quantum Spatial Orbital Cloud (QSOC) with up to 100 satellites to extend this infrastructure into orbit.
