WISeSat.Space begins Nasdaq trading after SPAC merger closes
WISeSat.Space Holdings Corp. began trading on the Nasdaq Capital Market under the ticker symbol "SAIQ" on 2 October 2026, following the close of its business combination with Columbus Acquisition Corp. (CAC) the previous day. CAC shareholders approved the deal at an extraordinary general meeting on 30 September. The listing establishes WISeSat.Space as an independently quoted public company, separating it from the broader WISeQey Corp. portfolio while retaining access to the group's cryptographic and semiconductor technologies.
WISeSat.Space is a subsidiary of WISeQey Corp., the British Virgin Islands-based holding company that also controls SEALSQ Corp. (Nasdaq: LAES), which develops post-quantum semiconductors and public key infrastructure (PKI) products. SEALSQ issued the announcement, noting the two entities operate as sister companies within the WISeQey group.
The deal
The transaction was structured as a standard de-SPAC business combination. Maxim Group LLC served as financial adviser to WISeSat.Space, with Ellenoff Grossman & Schole LLP as US legal counsel and Harney Westwood & Riegels handling British Virgin Islands law. Loeb & Loeb LLP represented CAC. No transaction value, post-deal capitalisation, or cash trust size was disclosed in the release.
Carlos Moreira, who serves as chief executive across SEALSQ, WISeQey and WISeSat.Space, said the Nasdaq listing "opens a new chapter" in the company's mission. He added: "As more devices and essential services rely on satellite connectivity, trust and post-quantum security must be built into the infrastructure from the outset."
WISeSat.Space says it has had satellites in orbit since 2024 and is developing communications infrastructure aimed at securing IoT device connectivity via satellite. Target verticals cited include remote monitoring, logistics, defence and infrastructure management. The company intends to embed hardware-based device authentication and post-quantum cryptographic protections directly into its satellite communications architecture.
Market context
The de-SPAC route to public markets has become less common since the 2021-2022 peak, with tightening SEC disclosure rules and weaker aftermarket performance dampening appetite. WISeSat.Space's listing nonetheless signals that niche deep-tech companies with a post-quantum angle are still finding SPAC partners willing to take them public.
The satellite IoT connectivity market is contested, with established players such as Iridium, Globalstar and Skylo competing against newer low-earth-orbit networks. Post-quantum security for satellite links is an emerging differentiation vector: NIST finalised its first set of post-quantum cryptography standards in 2024, and critical infrastructure operators in defence and logistics are beginning to assess which vendors can credibly embed those standards into hardware at the device level.
WISeSat.Space's reliance on the broader WISeQey ecosystem, including SEALSQ's semiconductor and PKI stack and WISeID's digital identity platform, positions it as a vertically integrated offering rather than a connectivity-only provider. Whether that integration translates into commercially differentiated products will depend on customer wins and demonstrated interoperability that the company has not yet disclosed publicly.
For investors, the near-term milestones to watch are confirmation of a named anchor customer, disclosure of satellite capacity and orbital parameters, and evidence that the post-quantum cryptographic layer meets recognised standards such as NIST FIPS 203 or 204 for key encapsulation and digital signatures.
