Analysis

The stock dropped -11.0% in the session following this news. A negative reaction despite a successful satellite launch fits prior divergence episodes where favorable defense and space news preceded drops of -10.98% and -10.01%. Before this announcement, WKEY traded at 8.6, well above its 200‑day MA of 6.5 but still 56.57% below its 52‑week high of 19.8. Low relative volume at 0.38x the 20‑day average may indicate limited conviction behind near-term moves.

6 terms

software-defined radio technical

"Key features include: Software-defined radio (SDR) technology, enabling flexible"

A software-defined radio is a radio system where functions traditionally done by fixed hardware—like tuning, filtering and decoding signals—are performed by software running on general-purpose processors. For investors, it matters because this flexibility can cut development costs, speed product updates, expand applications across markets, and concentrate value in software and services rather than specialized chips, while also raising considerations about regulatory compliance and cybersecurity.

sdr technical

"Software-defined radio (SDR) technology, enabling flexible in-orbit reconfiguration"

Special Drawing Rights (SDR) are an international reserve asset created by the International Monetary Fund that governments and central banks can use like a backup pool of currency. Their value is calculated from a basket of major currencies, and they can be exchanged between countries for usable money when a nation needs extra liquidity. For investors, SDR allocations affect global currency availability, sovereign debt comfort and confidence in a country's ability to meet obligations—similar to a household having an emergency line of credit that reduces the chance of sudden cash shortfalls.

post-quantum technical

"SEALSQ post-quantum chips, ensuring unprecedented levels of trust, privacy"

Post-quantum describes technology, especially encryption methods, designed to stay secure against powerful future quantum computers that could break today’s digital locks. For investors, it signals which products, services or suppliers are preparing for a major shift in cybersecurity risk—similar to choosing a safe built to resist a new kind of drill—affecting costs, liability, competitive advantage and regulatory compliance across industries.

quantum-safe key distribution technical

"constellation will also support quantum-safe key distribution for critical"

Quantum-safe key distribution describes methods for sharing the secret codes that protect digital information in ways designed to remain secure even if powerful quantum computers exist. Think of it as swapping a key for a locked box using a technique that a future super-powerful thief cannot easily copy or crack; for investors, adopting these methods reduces the risk of costly data breaches, regulatory penalties, and technology obsolescence, and can affect competitiveness and long-term value.

telemetry technical

"WISeSat provides secure command authentication and encrypted telemetry for"

Telemetry is the automatic collection and transmission of measurements from remote devices, systems, or patients to a central system for monitoring and analysis—like a car sending engine, speed and location data back to a dashboard. For investors it matters because telemetry provides real-time evidence of product performance, safety and user behavior, helping assess revenue potential, operational risk, regulatory compliance and whether a product is meeting market demand.

digital tokens financial

"supports the use of trusted digital tokens including SEALCOIN to enable"

Digital tokens are unique digital items recorded on a shared electronic ledger that represent value, rights, or access—like a digital ticket, coupon, or share that you can hold and transfer. They matter to investors because tokens can represent tradable assets or claims (for example ownership, a right to use a service, or a share of future revenue), so their price can change with demand, platform trust, and regulation, offering potential gains but also significant risks.

Geneva, Switzerland, December 1, 2025 –WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company, in cooperation with its subsidiaries, SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, and WISeSat.Space (“WISeSat”), which focuses on space technology for secure satellite communication, specifically for IoT applications, is pleased to announce the successful launch of its latest WISeSat satellite aboard a SpaceX mission. This achievement marks another significant milestone in WISeSat’s strategy to deploy a secure, resilient, and sovereign constellation enabling real-time, low-power, IoT and cybersecurity services worldwide.

The satellite was placed into orbit aboard a SpaceX Falcon 9 Transporter 16, further strengthening WISeSat’s collaboration with SpaceX as a trusted launch partner. With this new deployment, WISeSat continues to expand its constellation, offering enhanced coverage and improved data availability for industrial IoT applications, environmental monitoring, secure communications, and critical-infrastructure protection.

Carlos Moreira, CEO of WISeKey, SEALSQ and WISeSat, stated: “This successful launch with SpaceX represents a major step forward for WISeSat and for Europe’s capacity to operate sovereign space-based secure communications. The WISeSat constellation is designed to integrate seamlessly with SEALSQ post-quantum chips, ensuring unprecedented levels of trust, privacy, and resilience for the next generation of connected devices.”

The newly launched satellite will further reinforce WISeKey’s leadership at the intersection of cybersecurity, blockchain, IoT, and space technology. This next-generation satellite model is designed to significantly enhance the current constellation through a series of advanced technological innovations. These improvements deliver higher performance, greater resilience, and broader application potential. Key features include:

• Software-defined radio (SDR) technology, enabling flexible in-orbit reconfiguration and adaptation to evolving communication standards, ensuring long-term relevance and operational efficiency.
• Higher data-rate communications, supporting faster, more robust, and more secure data transfer for demanding IoT, cybersecurity, and mission-critical applications.

With this launch, WISeSat continues to position itself as a key player in the emerging European space industrial ecosystem, contributing to technological sovereignty while offering scalable commercial services for government, defense, and enterprise customers.

WISeSat provides secure command authentication and encrypted telemetry for Earth observation and defense missions. Beginning with its next launch planned for early 2026, the constellation will also support quantum-safe key distribution for critical infrastructure sectors, including energy, transportation, and smart cities. The platform enables the secure onboarding of billions of IoT devices by delivering quantum-resistant digital identities from orbit, extending trusted connectivity even to remote or underserved areas.

Technologies from WISeKey, SEALSQ, and Hedera are increasingly integrated across the WISeSat platform. This makes the constellation a benchmark for post-quantum security in space and supports the use of trusted digital tokens including SEALCOIN to enable secure space-to-ground transactions and tokenized satellite services.

WISeSat has recently expanded its ground infrastructure with a dedicated satellite antenna in La Línea, Spain, and additional installations planned in Switzerland. This growing network enhances real-time monitoring, mission control, and the secure management of the expanding constellation.
