WISeSat.Space Holdings Corp. Ordinary Shares

WISeSat.Space Holdings Corp. announced that its management team will ring the Nasdaq Opening Bell on Friday, October 9, 2026, celebrating the listing of its ordinary shares on Nasdaq and outlining its strategy to develop trusted, quantum-resilient space communications. Following the ceremony at 151 West 43rd Street, the company will host a Quantum Space Security Roundtable from 10:00 a.m. to 4:00 p.m. ET, bringing together experts in space, quantum technology and cybersecurity to discuss protecting satellite communications against emerging quantum computing threats. The roundtable will be held in two sessions moderated by Founder and CEO Carlos Moreira: the first, "Space Security and Sovereignty," will feature Jessica Rosenworcel, Executive Director of the MIT Media Lab and former Chair of the US Federal Communications Commission; Cristina Dolan, Non-Executive Director of SEALSQ; Liz Hanson, Managing Director of Technology Investment Banking at KeyBanc Capital Markets; and Mark Minevich, Strategic Partner at Mayfield and President of Going Global Ventures. The second session, "Building the Secure Space Stack," will feature Julián Fernández, CEO and Co-founder of FOSSA Systems; Nick Farina, Co-founder and CEO of EeroQ; and, from WISeSat.Space, Philip Hamelink, Interim Head; Gwenael Rouy-Poirier, Chief Financial Officer; and Alex Moreira, Satellite Sales Engineer. The event will highlight WISeSat.Space's role in supporting the planned Quantum Spatial Orbital Cloud roadmap, a SEALSQ-owned quantum and post-quantum service roadmap expected to leverage WISeSat satellite infrastructure as part of its future orbital layer, with the company intending to expand that orbital infrastructure through planned next-generation satellite missions.

WISeQey Corp., formerly WISeKey International Holding AG, began trading on Nasdaq and SIX today under the new symbol WQEY following its redomiciliation from Switzerland to the British Virgin Islands. The company also congratulated its subsidiary WISeSat.Space Holdings Corp., now listed on Nasdaq as SAIQ, which closed a $10 million private investment in public equity on October 1, 2026, from SEALSQ Corp, a fellow WISeQey subsidiary. The purchase price was $10.79 per share, equal to the redemption price from the business combination, and the subscription agreement includes a price-protection mechanism that may trigger additional share issuance to SEALSQ if the volume-weighted average price over the 10 consecutive trading days ending on the 60th calendar day after closing falls below the purchase price, subject to a $5.00 floor. The PIPE capital is intended to fund WISeSat.Space's satellite infrastructure expansion and the integration of post-quantum cryptography into its satellites, ground and user-segment architectures, while SEALSQ plans to use WISeSat.Space satellite capacity to deliver quantum and post-quantum services. Carlos Moreira serves as CEO of WISeQey, WISeSat.Space and SEALSQ, making the PIPE investment and planned collaboration related party transactions.

WISeSat.Space Holdings Corp. shares surged as much as 500% in Monday premarket trading after the company completed its previously announced reverse SPAC merger with Columbus Acquisition Corp. on October 1, 2026.

Founder, chairman and CEO Carlos Moreira is scheduled to ring the Nasdaq Opening Bell on October 9, 2026, at Nasdaq MarketSite in Times Square. The listing supports WISeSat.Space's plans to expand secure satellite connectivity, drawing on WISeQey's expertise in cybersecurity, digital identity and secure semiconductors to connect IoT devices beyond terrestrial networks. SAIQ was up 308.63% at $7.55 in premarket trading on Monday, hitting a new 52-week high.
