How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Key Terms

post-quantum cryptography, public key infrastructure, pipe, beneficial ownership

4 terms

post-quantum cryptography technical

"Secure semiconductors and post-quantum cryptography, through SEALSQ"

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.

public key infrastructure technical

"Digital identity and public key infrastructure, to authenticate people"

A public key infrastructure (PKI) is the system of digital keys, certificates and trusted procedures that proves who is on the other end of an electronic interaction and encrypts the data they exchange. Think of it as a verified digital mailroom and set of padlocks: one key is shared publicly to lock messages and a matching secret key unlocks them, which helps prevent fraud, supports secure transactions, regulatory compliance and preserves investor trust in a company’s digital operations.

pipe financial

"SEALSQ’s $10 million PIPE investment, completed alongside WISeSat."

A PIPE (private investment in public equity) is a deal in which institutional or accredited investors buy shares or convertible securities directly from a publicly traded company, usually at a discount to the market price. Companies use PIPEs to raise money faster than through a traditional public offering; for existing shareholders they matter because the newly issued shares add to the share count and can dilute ownership.

beneficial ownership financial

"WISeQey reports aggregate beneficial ownership of 26,405,355 shares"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

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.

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.
