Key Terms

5 terms

redomiciliation regulatory

"cross-border merger and redomiciliation"

Redomiciliation is when a company legally changes its country of incorporation while keeping the same business and assets, like moving a house to a new neighborhood but keeping the same furniture. Investors care because the company then follows a different set of laws and tax rules, which can change shareholder rights, reporting standards, dividend treatment and the ease of trading the stock, potentially affecting risk and return.

PIPE investment financial

"SEALSQ’s $10 million PIPE investment"

A pipe investment is a private sale of stock or convertible securities made directly to selected investors by a company that is already publicly traded, allowing the company to raise cash quickly without a full public offering. It matters to investors because it can dilute existing share value and change ownership stakes, but also signals that the company secured financing; like a homeowner taking a quick private loan to cover a repair, it can be a sign of needed funds or investor confidence.

as-converted basis financial

"including Class F shares on an as-converted basis"

As-converted basis means counting securities that can become common stock—like convertible bonds or preferred shares—as if they already were common shares when calculating totals such as shares outstanding, ownership percentages, or per-share metrics. Investors use it to see the potential dilution and the “what-if” size of the shareholder base; it’s like imagining all restaurant coupons have been redeemed so you know how crowded the table could become and how slices of the pie would shrink.

beneficial-ownership methodology regulatory

"under the filing’s beneficial-ownership methodology"

post-quantum security technical

"planned integration of post-quantum security"

Post-quantum security is the set of methods and standards designed to protect digital information from powerful future computers that use quantum physics. Think of it as upgrading a lock to one that cannot be picked by a new kind of super-advanced burglar; for investors, it matters because failing to adopt these protections can lead to data breaches, regulatory fines, costly system overhauls, and loss of customer trust that can hurt a company’s value.

WISeQey Issues CEO Letter to Shareholders: Building an Intelligent, Secure Platform for the Intelligence Age

Geneva, Switzerland – October 21, 2026 – WISeQey Corp. (formerly known as WISeKey International Holding AG, “WISeQey”) (Nasdaq/SIX: WQEY), a global quantum cybersecurity and space IoT company, today issued a Letter to Shareholders from its Founder, Chairman and Chief Executive Officer, Carlos Moreira, outlining the Group’s strategy and priorities following its redomiciliation and the Nasdaq listing of its space connectivity subsidiary, WISeSat.Space Holdings Corp (Nasdaq: SAIQ) (“WISeSat.Space”).

Dear Shareholders,

October marks an important new chapter for our Group. Following the successful completion of our cross-border merger and redomiciliation, WISeQey Corp. began trading on Nasdaq and the SIX Swiss Exchange under the unified ticker WQEY on October 5, 2026. This milestone establishes the corporate foundation for our next phase of development: bringing together the Group’s technologies to build trusted infrastructure for the Intelligence Age.

Alongside this achievement, our subsidiary WISeSat.Space successfully completed its business combination with Columbus Acquisition Corp., with its ordinary shares commencing trading on Nasdaq under SAIQ on October 2, 2026. The listing established a dedicated public-market platform to advance our ambition of bringing cybersecurity to space and delivering trusted satellite connectivity. As disclosed via the October 14, 2026 SEC filing, WISeQey remains WISeSat.Space’s largest shareholder, directly holding 23,387,061 WISeSat.Space shares, including Class F shares on an as-converted basis. Including the 3,018,294 shares held by SEALSQ, WISeQey reports aggregate beneficial ownership of 26,405,355 shares, representing approximately 88.5% of the ordinary-share class under the filing’s beneficial-ownership methodology.

The structure also allows each business to present a more focused investment proposition, while WISeQey works to connect complementary technologies and develop opportunities across the Group. Our objective is to combine the focus of dedicated public companies with the commercial advantages of collaboration across secure semiconductors, digital identity and satellite connectivity. With these transactions completed, our focus is on commercial execution, turning our technologies into customer deployments, building revenue-generating relationships and allocating capital to opportunities with a clear path to long-term shareholder value.

Building Trust Into Intelligent Systems

These milestones support a clear strategic objective: to integrate the Group’s complementary technologies into an intelligent, secure platform connecting people, devices, machines and satellites.

As artificial intelligence becomes embedded in everyday infrastructure, connected systems will increasingly exchange information, make decisions and initiate transactions autonomously. Their usefulness will depend on whether their identities, data and actions can be trusted. Our ambition is to provide that foundation of trust, from the semiconductor inside a device to the networks and services through which it operates.

We intend to bring together five complementary capabilities:

● Secure semiconductors and post-quantum cryptography, through SEALSQ, to establish hardware-based trust and strengthen protection against emerging threats.

● Digital identity and public key infrastructure, to authenticate people, devices and services and protect their interactions.

● Secure satellite connectivity, through WISeSat.Space, to extend trusted communications beyond terrestrial networks.

● Artificial intelligence, to support intelligent services operating with authenticated identities and protected data.

● Trusted machine transactions, through technologies such as SEALCOIN, to support secure interactions and exchanges between connected devices.

Our next step is to connect these capabilities by creating a platform in which a device can establish its identity, communicate securely, verify the origin and integrity of information, and participate in authorized transactions. We see potential applications across industrial automation, logistics, energy, connected mobility and critical infrastructure.

Connecting Our Capabilities

The collaboration between SEALSQ and WISeSat.Space illustrates this strategy in practice. SEALSQ’s $10 million PIPE investment, completed alongside WISeSat.Space’s business combination, provided capital to advance satellite infrastructure and support the planned integration of post-quantum security across space, ground and user systems. The collaboration aims to combine satellite capacity with secure semiconductors, cryptography and trusted identity helping customers authenticate connected devices and protect the data they exchange beyond the reach of terrestrial networks.

Our Priorities for Shareholder Value

For WQEY shareholders, our objective is to build long-term value through both our strategic holdings and turn the Group’s combined capabilities into revenue-generation commercial opportunities. Our listed subsidiaries provide focused platforms for development and financing, while WISeQey’s role is to drive collaboration, prioritize opportunities where our businesses are stronger together, and translate those advantages into long-term shareholder value.

Our priorities are execution, disciplined capital allocation and commercialization. We will focus on translating technology into customer deployments, expanding industrial partnerships and developing services that address concrete security and connectivity needs. We will evaluate investments against their commercial potential, funding requirements and expected contribution to shareholder value.

2

We enter this next chapter with a clear conviction: as intelligence becomes more distributed and autonomous, trust must be built into its foundations. WISeQey’s ambition is to help make that possible.

Thank you for your continued confidence and support. We are focused on earning that trust through disciplined execution, commercial progress and a sustained commitment to creating long-term value for you, our shareholders.
