WISeQey Announces Preliminary Nine-Month 2026 Financial Results and Provides Corporate Update

Consolidated revenue of $17 million, representing 55% year-over-year growth; reaffirms FY 2026 revenue guidance of 50% to 100% year-over-year growth

Subsequent WISeSat.Space Nasdaq listing establishes dedicated public-market platform for secure satellite connectivity

Geneva, Switzerland – November 3, 2026 – Ad hoc announcement pursuant to Art. 53 LR - WISeQey Corp. (formerly known as WISeKey International Holding AG, “WISeQey”, the “Company” or the “Group”) (Nasdaq/SIX: WQEY), a global quantum cybersecurity and space IoT company, today announced its preliminary unaudited financial metrics for the nine-month period ended September 30, 2026 ("9M 2026"), provided an update on corporate developments, and reaffirmed its full-year 2026 revenue guidance.

9M 2026 Key Financial Metrics

• Revenue growth of 55%: Preliminary unaudited 9M 2026 revenue of $17 million, compared to $11 million in 9M 2025.
• Strong liquidity: Group consolidated cash, cash equivalents and restricted cash of approximately $471.0 million at September 30, 2026.
• Subsidiary SEALSQ’s post-quantum pipeline exceeds $100 million: An active, evolving business pipeline of more than $200 million through 2029 as of October 15, 2026, including more than $100 million associated with Post-Quantum projects, including the QS7001 and QVault TPM.  These figures represent management estimates of potential opportunities and are subject to risks such as conversion risk, customer validation, technical integration and other commercial risks.
  
  

Revenue Drivers
The 9M 2026 increase was driven primarily by growth in the Group’s subsidiary, SEALSQ Corp (“SEALSQ”):

• Continued strong demand for SEALSQ's Vault-IC secure-element family across industrial, smart-energy IoT and P25 Radio protocol application deployments.
• Growth in recurring PKI subscriptions, certificate-management and digital identity services.
• Nine months of consolidated revenue from IC'Alps SAS, which contributed approximately $3.8 million in 9M 2026 through custom ASIC design and secure semiconductor engineering services.
• Ramp-up of the Quantix Edge Security sovereign semiconductor design and personalization center in Murcia, Spain.
• Initial sampling and evaluation revenue from QS7001 and QVault TPM as 42 customers are now evaluating the next generation of secure semiconductor products.
  
  

FY 2026 Revenue Outlook
WISeQey’s outlook statements are based on current expectations. The following statements are forward-looking and actual results could differ materially depending on market conditions and the factors set forth under "Forward-Looking Statements" below.  WISeQey reaffirms its FY 2026 revenue growth guidance of approximately 50% to 100%, representing a range of approximately $27 million to $36 million, compared with audited FY 2025 revenue of $19 million.

The Company expects a more significant contribution from its subsidiary SEALSQ’s post-quantum product lines in 2027 and beyond as customers complete technical integration and move into volume production. Timing remains subject to laboratory review, certification, customer qualification and procurement.

Carlos Moreira, Founder, Chairman and Chief Executive Officer of WISeQey, commented: “Our focus is converting our technology portfolio into customer deployments and sustainable commercial growth. SEALSQ’s revenue progress, together with WISeSat.Space Holdings Corp.’s (NASDAQ: SAIQ) (“WISeSat.Space”) subsequent Nasdaq listing, strengthens the foundations for the next stage of our development. We are connecting hardware security, trusted identities and satellite communications to address the needs of increasingly intelligent and autonomous systems. Our priorities remain on execution, converting commercial opportunities into customer deployments, allocating capital with discipline and building sustainable value for WISeQey shareholders.”

Corporate Developments
During January - October 2026, WISeQey’s announcements focused on digital identity, post-quantum semiconductors, quantum computing and secure satellite infrastructure, alongside corporate restructuring and preparations for subsidiary listings.

• WISeQey corporate transition. On October 5, 2026, following its cross-border merger and redomiciliation, WISeQey began trading on Nasdaq and SIX under the symbol WQEY.
• WISeSat.Space listing and ownership. On October 1, 2026, WISeSat.Space completed its combination with Columbus Acquisition Corp. and commenced trading on the Nasdaq under the symbol SAIQ on October 2, 2026.  WISeQey remains the ultimate parent company of WISeSat.Space and directly holds 23,387,061 WISeSat.Space shares, including 11,430,139 Ordinary Shares and 11,956,922 Class F shares. WISeQey’s subsidiary, SEALSQ Corp, holds 3,018,294 shares, split between 1,977,816 Ordinary Shares and 1,040,478 Class F Shares.  This brings WISeQey’s reported aggregate beneficial ownership totals to 26,405,355 shares, approximately 88.5% of the ordinary-share class on an as-converted basis.
• Expansion of the SEALQuantum Sovereign Vertical Stack. Through SEALSQ, the Group completed the acquisition of Miraex, invested approximately €15 million in Quobly, increased its total EeroQ investment to $7 million and made a majority investment in Wecan. This is a strategic quantum initiative through which the Group allocates its own capital across quantum and post-quantum technologies with the aim to develop a Sovereign Quantum Vertical Stack.
• Creation of Quantisimo. In June, WISeKey and SEALSQ established Quantisimo Corp. and announced a non-binding LOI with GigCapital8 regarding a Nasdaq-listed pure-play quantum platform. On October 9, 2026, WISeQey and SEALSQ entered into a definitive merger agreement with GigCapital8, Quantisimo and Quantisimo Holdings Corp. (“PubCo”), under which Quantisimo and GigCapital8 will become wholly owned subsidiaries of PubCo, which is expected to list on the Nasdaq Capital Market. Prior to closing, WISeQey and SEALSQ will contribute to Quantisimo certain of their equity interests in Miraex, SEALCOIN, Wecan and WISeSat.Space. Upon closing, WISeQey and SEALSQ will receive an aggregate of 66,610,000 shares of the new publicly listed holding company, Quantisimo Holding Corp. (“PubCo”), implying a pro forma equity value for Quantisimo of approximately $666.1 million at $10.00 per share, and are expected to hold a majority of PubCo’s outstanding ordinary shares.   Closing is subject to, among other conditions, available cash of at least $15 million, approval by GigCapital8’s shareholders, regulatory approvals, effectiveness of a registration statement on Form F-4, Nasdaq listing approval, and there can be no assurance that it will be completed on the contemplated terms or at all. The Group continues to target completion during the first quarter of 2027.
• Satellite infrastructure and international partnerships. WISeSat.Space announced completion of a Swiss Space Command pilot phase in April and the planned development of the Quantum Spatial Orbital Cloud in conjunction with SEALSQ. On October 20, 2026, WISeSat.Space confirmed the successful launch and deployment of FOSSASAT-2E27, a new-generation 6U satellite developed and operated by its longstanding strategic partner FOSSA Systems ("FOSSA"), aboard SpaceX's Falcon 9 Bandwagon-5 mission. The partnership, supported by successive investments, aims to validate the technology across up to six satellite missions amid expectations of accelerating demand for quantum-resistant security. The collaboration is expected to support the progressive validation of VaultIC secure elements and, subject to technical readiness and integration, the next-generation QS7001 post-quantum secure element.
• Post-quantum commercialization. SEALSQ advanced validation and customer sampling of its QS7001 and QVault TPM products. Its estimated commercial pipeline as of October 15, 2026 exceeded $200 million through 2029, including more than $100 million associated with post-quantum projects. These represented potential opportunities, rather than combined revenues, and remain subject to conversion into revenue.

Digital identity and the machine economy. In June 2026, WISeQey’s SEALCOIN subsidiary announced a $4 million investment commitment supporting SEALCOIN infrastructure, including a $1 million commitment from The Hashgraph Group (“THG”), with the object to accelerate the integration of the SEALCOIN ecosystem into the rapidly emerging space economy. In addition, WISeQey is targeting further integration of WISeID into Wecan’s compliance solutions and participation in Hedera’s strategic and community partner network.

• Swiss infrastructure. In September, the Group announced the signature of a memorandum of understanding with the Canton of Jura for the establishment of a post-quantum semiconductor and cybersecurity center in the Canton of Jura. The proposed Jura Center represents an indicative public-private investment of approximately CHF 40-60 million over a period of approximately six years and is intended to establish a strategic Swiss capability for the design, personalization, testing and secure provisioning of next-generation post-quantum semiconductor technologies.
