Pattern Detected

Strategic and partnership news has often moved the stock, but reactions have been mixed, with both strong rallies and double-digit pullbacks following positive updates.

Recent Company History

Over the last few months, WISeKey has focused on satellite expansion, space partnerships, and corporate restructuring. A WISeSat.Space launch on Dec 1, 2025 and a Swiss Armed Forces collaboration both saw double-digit declines despite positive strategic content. By contrast, the INNOSPACE MoU on Oct 29, 2025 and the WISeSat SPAC deal on Nov 10, 2025 drove gains above 5%. The November redomiciliation plan to the BVI also drew a positive reaction, underscoring investor sensitivity to structural and capital-markets positioning.

Market Pulse Summary

The stock surged +19.5% in the session following this news. A strong positive reaction aligns with the CEO’s emphasis on convergence across semiconductors, satellites, blockchain, and digital identity, backed by a cash position above $440 million. Historically, strategic deals like the INNOSPACE MoU and WISeSat SPAC agreement produced sizable gains, while some technically positive updates saw selloffs. Investors evaluating a sharp move would need to weigh this mixed reaction history, the execution risk around 2026 milestones such as the WISeSat listing and QAIT Token launch, and the fact that the stock remained well below its $19.80 52-week high pre-letter.

Key Terms

spac financial

"The upcoming listing of WISeSat, via a merger with a SPAC:"

A special purpose acquisition company (SPAC) is a company formed specifically to raise money through an initial public offering (IPO) with the goal of buying or merging with an existing private company. For investors, a SPAC offers a way to invest in a potential future business without initially knowing which company it will acquire, making it a way to access new investment opportunities that might otherwise be difficult to invest in directly.

token financial

"SEALCOIN’s preparations for the launch of the QAIT Token in Q1 2026:"

A token is a digital unit of value created on a blockchain that can represent money, access rights, ownership stakes, or unique items; think of it like a digital ticket or coupon that can be traded, used, or collected. Investors care because tokens can carry financial value, entitle holders to returns or governance rights, and their supply, legal status, and market demand affect price and risk in ways similar to stocks or commodities.

iot technical

"satellite-based cybersecurity and IoT ecosystem and enabling WISeSat"

The Internet of Things (IoT) describes a network of everyday devices—such as appliances, vehicles, and equipment—that are connected to the internet and can share data automatically. For investors, IoT represents a growing trend that can drive efficiency and innovation across many industries, potentially creating new opportunities for growth and value. Its expansion influences how companies operate and compete in a digitally connected world.

pki technical

"the WISeID platform provides the PKI infrastructure securing digital identities"

PKI (Public Key Infrastructure) is a system that creates and manages digital “keys” and electronic certificates to prove identities and secure online communications, like a bank vault and ID card for data. For investors, PKI matters because it helps prevent fraud, ensures that financial documents and trading instructions are genuine, and reduces regulatory and operational risk tied to hacked accounts or tampered disclosures.

post-quantum cryptography technical

"our global leadership in post-quantum cryptography and space connectivity"

Post-quantum cryptography is a set of new methods for scrambling data so it stays secure even if powerful quantum computers exist; think of replacing today’s locks with designs that a future high‑speed lockpicker cannot open. For investors, it matters because companies must upgrade systems, meet regulations, and protect customer and trade data—creating costs, competitive advantages, or legal and reputational risks depending on how quickly and effectively they adopt these new security standards.

blockchain technical

"satellites, blockchain, and digital identity, into unified and interoperable ecosystems."

A blockchain is a digital record-keeping system that securely stores information across many computers, making it difficult to alter or tamper with. Think of it like a shared, unchangeable ledger that everyone can see and verify, ensuring transparency and trust. For investors, this technology offers a way to securely track transactions and assets without relying on a central authority, potentially reducing costs and increasing security.

satellite constellation technical

"Our satellite constellation is purpose-built to deliver trusted IoT connectivity"

A satellite constellation is a coordinated group of satellites working together in complementary orbits to provide continuous coverage or services over large areas, like a fleet of delivery trucks positioned to serve an entire city. For investors it matters because constellations enable scalable, ongoing revenue from services such as communications, navigation, or Earth observation, while also requiring large upfront capital, regulatory approvals and operational expertise that affect risk, growth potential and competitive advantage.

Geneva, Switzerland, December 22, 2025 – WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company, today issued a Letter to Shareholders by its Founder and CEO, Carlos Moreira.

Dear Shareholders,

As we close 2025, I would like to take a moment to reflect on what has been an exceptional year for the WISeKey Group of Companies.

2025 marked a significant milestone year in the execution of WISeKey’s long-term strategy as a technology holding company and innovation platform, with a mission to create a secure, connected, and quantum-resilient future.

Our proven model, successfully demonstrated by the 2023 listing on Nasdaq of our Semiconductors, PKI, and Post-Quantum technology subsidiary, SEALSQ’s Corp (NASDAQ: LAES) ("SEALSQ"), which continued to gain strong market validation in 2025 via its uplisting on NASDAQ Global Select tier, being recognized as one of the fastest-growing technology companies in the emerging quantum era.

This momentum for WISeKey was further reinforced by several milestones at our subsidiaries, including:

• The strategic acquisition of IC’ALPS in mid-2025: The acquisition of IC’ALPS, a leading ASIC design company, added 100 highly skilled engineers and experts to the Group, brought WISeKey’s total workforce to approximately 300 employees worldwide and significantly strengthened its semiconductor design and innovation capabilities.
• The launch of a $100 million Quantum Fund in mid-2025: The Quantum Fund is accelerating innovation across the quantum ecosystem, with initial investments already completed in promising startups such as ColibryTD and EeroQ.
• The commercial launch of our Quantum Shield QS7001™ and QVault™ TPM solutions: The launch, strategically positions WISeKey at the forefront of the digital trust revolution and marks the start of a clear and sustained growth phase for WISeKey, is backed by the establishment of European Personalization Centers and our global leadership in post-quantum cryptography and space connectivity, we are.
• The upcoming listing of WISeSat, via a merger with a SPAC: The merger, which is expected to be completed in the first half of 2026, aims to accelerate the commercialization of our satellite-based cybersecurity and IoT ecosystem and enabling WISeSat to emerge as a new, independent publicly listed space-tech company on Nasdaq. Our satellite constellation is purpose-built to deliver trusted IoT connectivity from space, secured by SEALSQ post-quantum cryptographic chips and anchored in the WISeKey Root of Trust.
• SEALCOIN’s preparations for the launch of the QAIT Token in Q1 2026: The primary function of the QAIT Token is to facilitate decentralized payments and validate communication between IoT devices and AI agents on the SEALCOIN platform. It is central to building a "transactional Internet of Things" where devices can autonomously interact and pay for services.
  
  

These strategic initiatives are underpinned by a very strong balance sheet supported by cash position of over $440 million as of December 19, 2025, providing WISeKey with exceptional financial flexibility to execute its growth strategy, pursue selective acquisitions, and invest in breakthrough technologies.

Our Vision
WISeKey has now entered its ‘Year of Convergence’ by bringing together four foundational pillars: semiconductors, satellites, blockchain, and digital identity, into unified and interoperable ecosystems. This convergence allows us to offer end-to-end solutions where each component reinforces the other, enabling exponential innovation and resilience.

By integrating semiconductors, trust services, satellites, blockchain, digital identity, and certified digital assets into a unified architecture of trust, WISeKey is no longer operating isolated businesses, but a single, interconnected ecosystem. A clear example of this Convergence was announced on October 1, 2025, with the introduction of a new suite of solutions designed to protect AI operations and decision-making processes against adversarial quantum attacks. This breakthrough builds on SEALSQ’s pioneering expertise in post-quantum cryptography and trusted semiconductor technologies, combined with SEALCOIN’s verifiable identity, decentralized execution, and post-quantum-resilient blockchain infrastructure.

Operating as a technology holding company and innovation platform, leveraging a disciplined and repeatable strategy across its portfolio of subsidiary companies, each entity within the WISeKey ecosystem follows a structured growth pathway, from incubation and technological validation to market expansion and, ultimately, public listing.

This approach enables WISeKey to unlock the intrinsic value of its innovations, attract strategic investors, and maximize shareholder returns. By methodically preparing and listing subsidiaries across cybersecurity, semiconductors, space technology, blockchain, digital identity, and now certified digital assets, WISeKey is building a resilient and diversified technology group that supports long-term value creation and global leadership in trusted digital ecosystems.  

Specifically…

• SEALSQ, which is at the heart of WISeKey’s convergence strategy, develops post-quantum secure chips such as the QS7001™ and QVault™ TPM. These technologies are engineered for mission-critical sectors including defense, IoT, satellites, automotive, smart cities, and AI systems, providing robust protection against “harvest-now, decrypt-later” threats. They are designed to generate both one-time hardware revenues and recurring income through chip personalization services delivered via Outsourced Semiconductor Personalization and Test centers.
• Designed for interoperability, these secure chips connect directly with the WISeSat.Space satellite constellation, including the 23^rd satellite scheduled for launch in November 2025, while SEALCOIN enables autonomous, chip-level transactions that unlock transaction-based revenue across the machine-to-machine and transactional IoT economy.
• Complementing this ecosystem, the WISeID platform provides the PKI infrastructure securing digital identities, devices, and transactions, supporting applications such as Matter Protocol certification for smart home devices and GSMA eUICC digital identity services.
• Preparing for 2026, the WISe.ARt platform is expanding beyond the art world to enable certified digital assets and digital twins for the luxury sector and a broad range of real-world and digital assets, leveraging WISeKey’s trust, identity, and blockchain technologies to bring authenticity, traceability, and value preservation to new markets.

Expanding Global Footprint
Through SEALSQ, WISeKey has also expanded its Quantum Corridor initiative with projects in India, the United Arab Emirates, and Brazil, strengthening regional post-quantum cryptography infrastructure and supporting the development of sovereign semiconductor ecosystems. These initiatives reflect WISeKey’s commitment to building a globally integrated post-quantum ecosystem connecting Europe, Asia, the Middle East, and Latin America through trusted semiconductor innovation and secure digital infrastructure.

Our progress is further reinforced by strategic initiatives such as the Quantix Edge Security project in Spain, positioning WISeKey at the heart of Europe’s semiconductor sovereignty strategy; collaboration with the Swiss Army, integrating WISeSat, SEALSQ, and SEALCOIN technologies into a single sovereign communications framework; and the HUMAN-AI-T initiative with the United Nations, which places WISeKey at the forefront of global AI governance and reinforces our leadership at the intersection of AI, security, and trust.

Redomiciliation to the British Virgin Islands
The recently announced plan to change our jurisdiction of incorporation from Switzerland to the British Virgin Islands is expected to provide WISeKey with enhanced strategic and operational flexibility. This transition is intended to improve access to equity capital markets in both the United States and Switzerland and to support future strategic acquisitions. Upon completion of the redomiciliation, WISeKey expects its ordinary shares to be primarily listed on Nasdaq, with a secondary listing on the SIX Swiss Exchange, continuing WISeKey Switzerland’s current presence on SIX.

We are entering 2026, with strong momentum, expanded capabilities, a growing global team, a solid financial foundation, and an increasingly broad portfolio of trusted digital services. As the quantum era rapidly approaches, WISeKey continues to innovate and expand its solutions, ensuring that organizations, governments, and individuals can operate with confidence in an increasingly complex technological landscape. We are confident that our strategic initiatives and technological advancements will drive sustainable growth and reinforce our leadership within the global cybersecurity and digital trust ecosystem.

On behalf of our entire management team and board of directors, I would like to sincerely thank our employees, partners, customers, and shareholders for their trust, commitment, and continued support.

We wish you all happy holidays and a prosperous 2026.

Regards
Carlos Moreira
Founder and CEO
