WISeKey Reports First Half 2026 Financial Results, Accelerates Quantum and Post-Quantum Strategy and Provides Outlook

Post-quantum pipeline above $100 million: The commercial pipeline as of September 22, 2026, at subsidiary SEALSQ Corp (Nasdaq: LAES) (“SEALSQ”) exceeds $225 million through 2029 and contains more than $100 million associated with the Company’s Post-Quantum projects, including the QS7001 and QVault TPM. It reflects rising demand as governments, enterprises and critical infrastructure operators prepare to move to quantum-resistant cryptography. These figures represent management estimates and are subject to risks such as conversion risk, customer validation, technical integration and other commercial risks.

Over $495 million in cash and restricted cash and minimal debt: At June 30, 2026, the Group held approximately $495 million in cash and restricted cash and had minimal debt.

Funding the next phase of growth: This financial strength lets WISeKey keep investing in post-quantum semiconductor commercialization, quantum technologies, sovereign infrastructure and strategic acquisitions, with a long-term investment horizon. FY 2026 guidance reaffirmed: WISeKey expects FY 2026 revenue growth of 50% to 100% year over year. Carlos Moreira, Founder, Chairman and Chief Executive Officer of WISeKey, said: “2026 is the year the technologies and investments we have built over many years are coming together as one commercial ecosystem, and WISeKey is entering the most important commercialization phase in its history. First-half revenue grew approximately 116%, and we ended June with approximately $495 million in cash and restricted cash and minimal debt. That gives us a strong financial foundation to execute our strategy.

“Our momentum continued into the third quarter. Shareholders approved our redomiciliation, which clears the way for a direct listing on Nasdaq. We advanced the WISeSat and Quantisimo transactions, began commercializing our Quantum Spatial Orbital Cloud, and signed an agreement with the Canton of Jura to develop a sovereign post-quantum semiconductor center in Switzerland.

“Our priorities are now clear and measurable: convert the SEALSQ pipeline into revenue, bring our post-quantum products into volume production, complete the WISeSat and Quantisimo transactions, and expand our sovereign semiconductor infrastructure. Looking beyond 2026, we are building a group in which WISeKey, SEALSQ, WISeSat, and Quantisimo can each grow as focused businesses while remaining connected through one trusted infrastructure. From silicon to qubits, from identity to AI, and from Earth to space, our mission is unchanged: to provide the Root of Trust for the next generation of the digital economy.”

Strategic Developments

WISeKey Redomiciliation and Planned Direct Nasdaq Structure

WISeKey advanced its strategy to simplify its corporate structure and strengthen its access to U.S. and international capital markets. On June 26, 2026, WISeKey signed a merger agreement to move the domicile of its holding company from Switzerland to the British Virgin Islands. WISeKey’s British Virgin Islands subsidiary, WISeQey Corp. (formerly known as WISeKey International Corp., “WISeQey”) filed a registration statement on Form F-4 with the U.S. Securities and Exchange Commission on July 16, 2026, and the SEC declared it effective on July 31, 2026. At an Extraordinary General Meeting held on September 9, 2026, shareholders approved the redomiciliation and the related merger agreement. On September 16, 2026, the subsidiary, which will become the Group’s new parent company, changed its name to WISeQey Corp.

The redomiciliation is expected to take effect on October 1, 2026, with WISeQey ordinary shares expected to begin trading under the ticker “WQEY” on or about October 5, 2026 on both the Nasdaq Global Market and the SIX Swiss Exchange, which will remain the primary listing. The WISeQey ordinary shares will trade directly on Nasdaq, replacing WISeKey’s existing American Depositary Shares and providing the Group with a more streamlined U.S. capital markets presence while preserving its international footprint. WISeQey’s operational headquarters and place of effective management will remain in Switzerland, and the Group’s businesses and operations are not expected to change. Completion of the redomiciliation remains subject to the remaining closing conditions and the applicable Swiss and British Virgin Islands procedures.

This simplified structure, together with the planned independent listings of WISeSat and Quantisimo, is designed to give investors clearer visibility into the value and performance of each of the Group’s technology platforms.

Quantisimo: Creating a Quantum Technology Pure-Play

In June 2026, WISeKey and SEALSQ established Quantisimo Corp. and executed a non-binding Letter of Intent with GigCapital8 Corp. (Nasdaq: GIW) regarding a potential business combination designed to create a Nasdaq-listed quantum technology company. The initial transaction contemplated an enterprise value of approximately $575 million.

Quantisimo is being designed to bring together selected technologies and investments developed through the SEALQuantum ecosystem, creating a vertically integrated platform spanning quantum computing, photonics, quantum-secure infrastructure and related technologies.

The proposed transaction remains subject to definitive agreements, regulatory review, shareholder approvals and customary closing conditions. The Group is targeting completion of the transaction during the first quarter of 2027, subject to satisfaction of these conditions.

SEALQUANTUM Sovereign Vertical Stack: Building the Root-to-Qubit Technology Stack

SEALSQ continued to execute its SEALQUANTUM Sovereign Vertical Stack strategy, backed by a targeted allocation of up to $200 million of SEALSQ’s internal capital resources. The strategy aims to build a sovereign, vertically integrated quantum technology stack. It runs from the cryptographic Root of Trust and post-quantum semiconductors through photonics and quantum computing. Key milestones include:

SEALSQ completed its acquisition of Miraex SA in Switzerland, adding quantum photonics interconnect technology. SEALSQ invested approximately €15 million in Quobly in France as a lead investor in Quobly’s €115 million Series A financing, and subsequently signed a $5 million commercial agreement. SEALSQ has invested a total of $7.0 million in EeroQ, a U.S.-based quantum computing company. SEALSQ made a majority investment in Wecan Group, and WISeKey is working with Wecan to develop and deploy the next generation of Wecan’s Co-Pilote compliance solution, aiming to integrate post-quantum financial security solutions for the global financial industry. These assets complement the Group’s in-house semiconductor, PKI and secure infrastructure capabilities into an integrated architecture “Root-to-Qubit.

The WISeKey Quantum RootKey ties these assets together. It extends the Root of Trust that WISeKey has operated under the OISTE Foundation governance model since 1999 into the post-quantum and quantum computing era. WISeKey has begun integrating the Quantum RootKey across the SEALQUANTUM Sovereign Vertical Stack ecosystem, anchoring each asset to a common, quantum-resistant trust layer that spans from chips to qubits.

Post-Quantum Semiconductors Enter Commercialization Phase

SEALSQ’s semiconductor business remains the Group’s technology foundation.

In 2026, SEALSQ reached several certification and security milestones for its QS7001 post-quantum secure element and QVault TPM product lines. QS7001 received NIST SP 800-90B Entropy Source Validation, a required step toward FIPS 140-3 and Common Criteria EAL5+ certification. It also completed Common Criteria fault-injection and side-channel resistance testing for both the QS7001 and QVault product lines. Engineering samples of the QVault TPM are now available to customers. SEALSQ separately received NIST FIPS 140-3 Level 3 certification for its VaultIC408 secure element. WISeKey believes the shift to post-quantum cryptography required by regulators in the United States and Europe is creating a multi-year commercial opportunity for SEALSQ. The Group expects first revenues from its post-quantum products in Q4 2026, with larger contributions anticipated in 2027.

As of June 30, 2026, more than 150 customers and prospects were engaging with SEALSQ’s post-quantum technologies, and more than 30 were actively evaluating or integrating QS7001 and QVault TPM.

As of September 22, 2026, SEALSQ’s commercial pipeline exceeded $225 million through 2029, including more than $100 million tied to post-quantum projects. The pipeline reflects management estimates of potential opportunities. Turning it into recognized revenue will depend on customer qualification, certification, production schedules and other factors.

WISeSat and the Quantum Spatial Orbital Cloud

WISeSat continued progressing toward becoming an independently listed space technology company. Following the public filing of the Form F-4 registration statement in June 2026 and effectiveness of such registration statement in August 2026 in connection with the proposed business combination with Columbus Acquisition Corp. (Nasdaq: COLA), WISeSat continued preparing for the transaction and its intended Nasdaq listing under the ticker SAIQ, subject to shareholder approval, Nasdaq approval and other closing conditions.

At the International Space Summit in Paris in September 2026, WISeKey, SEALSQ and WISeSat presented the commercial Quantum Spatial Orbital Cloud (“QSOC”) initiative.

QSOC is designed to combine WISeSat’s satellite constellation with SEALSQ post-quantum semiconductors, PKI, quantum random-number generation and identity technologies to establish secure and sovereign orbital infrastructure.

The current roadmap contemplates progressive deployment of a constellation of up to 100 satellites through 2033, designed to provide secure communications, quantum-generated trust and post-quantum identity services to governments, defense organizations, financial institutions, critical infrastructure and enterprises.

WISeKey Joins the Hedera Council Network

In September 2026, WISeKey announced that it had joined the Hedera Council network of strategic and community partners, further strengthening the technological foundation supporting its trusted machine-economy strategy.

The collaboration supports WISeKey’s broader objective of combining trusted digital identity, secure hardware, distributed- ledger infrastructure and machine-to-machine transactions. This architecture is particularly relevant to SEALCOIN, where autonomous devices, AI agents, robots and satellites can be provided with verifiable identities and mechanisms for trusted transactions.

New Swiss Post-Quantum Semiconductor and Cybersecurity Center

On September 21, 2026, WISeKey, SEALSQ and the Republic and Canton of Jura signed a Memorandum of Understanding to work together on a Post-Quantum Semiconductor and Cybersecurity Center in the Canton of Jura, Switzerland. The proposed public-private initiative has an indicative investment of approximately CHF 40 million to CHF 60 million over six years.

The Center is intended to give Switzerland its own capabilities to design, personalize, test and securely provision next- generation post-quantum semiconductors, starting with SEALSQ’s QS7001 Quantum Shield. The initiative targets approximately 40 direct jobs within two years, 150 by Year 5 and more than 250 by Year 8, and at least 60% of positions are expected to go to Canton residents.

The Jura project builds on the model of Quantix Edge Security in Murcia, Spain, where WISeKey and SEALSQ are developing sovereign semiconductor design, personalization and cybersecurity capabilities. Together, Murcia and Jura are intended to become key hubs in the WISeKey/SEALSQ Quantum HighwayTM, which links post-quantum semiconductor, quantum, cybersecurity and trusted infrastructure capabilities across multiple regions.

Geneva Quantum Center of Excellence

WISeKey and SEALSQ are also establishing the Geneva Quantum Center of Excellence at the Group’s new headquarters in Pont-Rouge.

The Center is designed as a physical convergence point for the Group’s quantum computing, post-quantum cybersecurity, secure semiconductor, digital identity, satellite, robotics and artificial-intelligence technologies.

The objective is to provide customers, governments, technology partners, regulators and investors with an end-to-end demonstration environment showing how the different components of WISeKey’s trusted technology ecosystem operate together.
