Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties.
These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many factors could cause actual future events to differ materially from the forward-looking statements in this communication, including but not limited to: (i) the risk that the Business Combination may not be completed in a timely manner or at all, which may adversely affect the price of CAC’s and the Seller’s securities; (ii) the risk that the Business Combination may not be completed by CAC’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by CAC; (iii) the failure to satisfy the conditions to the consummation of the Business Combination, including the approval of the Business Combination Agreement by the shareholders of CAC, the satisfaction of the closing requirements and the receipt of certain governmental, regulatory and third party approvals; (iv) the occurrence of any event, change or other circumstance that could give rise to the termination of the Business Combination Agreement; (v) redemptions exceeding anticipated levels; (vi) the failure to meet Nasdaq initial listing standards in connection with the consummation of the Business Combination; (vii) the effect of the announcement or pendency of the Business Combination on the Company’s business relationships, operating results, and business generally; (viii) risks that the Business Combination disrupts current plans and operations of the Company and the Seller; (ix) the outcome of any legal proceedings that may be instituted against CAC, Pubco, the Company or the Seller related to the Business Combination Agreement or the Business Combination; (x) changes in the markets in which the Company competes, including with respect to its competitive landscape, technology evolution, or regulatory changes; (xi) changes in domestic and global general economic conditions; (xii) the risk that Pubco and the Company may not be able to execute their growth strategies; (xiii) risks related to supply chain disruptions; (xiv) the risk that Pubco may not be able to develop and maintain effective internal controls; (xv) costs related to the Business Combination and the failure to realize anticipated benefits of the Business Combination or to realize estimated pro forma results and underlying assumptions, including with respect to estimated shareholder redemptions; (xvi) the ability to recognize the anticipated benefits of the Business Combination and to achieve commercialization and development plans, and identify and realize additional opportunities, which may be affected by, among other things, competition, the ability of the Company to grow and manage growth economically and hire and retain key employees; (xvii) inability to achieve successful results or to obtain licensing of third-party intellectual property rights for future discovery and development of the Company’s projects; (xviii) failure to commercialize products and achieve market acceptance of such products; (xix) the risk that the Company will need to raise additional capital to execute its business plan, which may not be available on acceptable terms or at all; (xx) the risk that Pubco will experience difficulties in managing its growth and expanding operations; (xxi) the risk of product liability or regulatory lawsuits or proceedings relating to the Company’s business; (xxii) risks associated with intellectual property protection; (xxiii) the risk that the Company is unable to secure or protect its intellectual property and (xxiv) those factors discussed in documents of CAC and Pubco filed or to be filed with the SEC, including in the registration statement relating to the Business Combination (the “Registration Statement”).

The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that will be described in the “Risk Factors” section of the Registration Statement and the amendments thereto, and other documents to be filed by CAC and Pubco from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and while the Pubco and CAC may elect to update these forward-looking statements at some point in the future, they assume no obligation to update or revise these forward-looking statements, whether as a result of new information, future events or otherwise, except as required by applicable law. None of Pubco, the Seller, the Company or CAC gives any assurance that Pubco, the Seller, the Company or CAC will achieve expectations. These forward-looking statements should not be relied upon as representing Pubco’s, CAC’s, the Seller’s or the Company’s assessments as of any date subsequent to the date of this Current Report.

WISESAT OVERVIEW
WISeSat, through its subsidiary WISeSat.Space AG, provides a next-generation satellite platform, developed by WISeKey and WISeSat, designed to deliver secure, cost-effective, and globally accessible IoT connectivity. Leveraging post-quantum cryptographic chips of SEALSQ Corp (NASDAQ: LAES) (“SEALSQ”), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products and also subsidiary of WISeKey, WISeSat satellites are equipped with advanced encryption, authentication, and identity management systems, including WISeKey’s Root of Trust and WISeID. These satellites enable real-time, quantum-resilient communication for industries such as logistics, agriculture, energy, and defense. With support for Hedera distributed ledger technology, WISeSat technology is designed to ensure data integrity and transparency across its decentralized network. The constellation is part of a broader initiative to safeguard digital communications against emerging quantum threats while enabling scalable, autonomous IoT infrastructure from space. WISeSat and its partners have launched 22 satellites in orbit with 14 of these currently operational as part of its Low Earth Orbit (LEO) constellation. WISeSat is actively expanding this network and is aiming to deploy a total of 100 satellites by 2030. These satellites are designed to provide secure, post-quantum IoT connectivity for industries such as agriculture, logistics, defense, and environmental monitoring.
In November 2025, WISeSat is set to launch its next-generation post-quantum-secure satellite, which is equipped with SEALSQ’s Quantum Shield technology, aboard a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California. This satellite will serve as a testbed for post-quantum communication protocols from space, a pivotal step in developing quantum-resilient satellite-based IoT connectivity via satellite infrastructure. The mission underscores WISeSat’s commitment to pioneering secure, sovereign, and sustainable space communications that can withstand the cybersecurity challenges posed by quantum computing.
MANAGEMENT COMMENTARY
Carlos Moreira, Founder and CEO of WISeKey, noted, “This milestone transaction marks a defining moment in WISeKey’s mission to build a secure, sovereign and quantum-resilient satellite infrastructure for the world. By combining WISeSat with Columbus, we are accelerating 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 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. As quantum computing transforms the global cybersecurity landscape, WISeSat is pioneering a future in which critical data, devices, and infrastructures are protected end-to-end, from Earth to orbit. We believe this business combination strengthens our capital base and positions WISeSat to scale from a network of 14 satellites already in orbit to the targeted deployment of 100 further satellites by 2030, reinforcing Europe’s technological sovereignty and leadership in secure space systems. We look forward to continuing this journey as we deploy the world’s first post-quantum-secure satellite platform and shape the foundation of trusted digital communications for the decades ahead.”
Fen Zhang, Chairman and CEO of Columbus, said, “The Columbus team is excited to announce this transaction with WISeSat, a pioneer in cutting-edge satellite technology. WISeSat is well positioned to capture significant opportunities in secure satellite communications, and this transaction represents a compelling value proposition that we believe will deliver long-term benefits for our shareholders.”
THE BUSINESS COMBINATION AGREEMENT
Pursuant to the proposed Business Combination Agreement, each of Columbus, and WISeKey’s wholly owned subsidiary, WISeSat, will become wholly owned subsidiaries of Pubco, a newly formed British Virgin Islands holding company expected to be listed on Nasdaq. In the business combination, all shares of WISeSat will be exchanged for the right to receive shares of Pubco. As a result, upon closing, WISeKey will receive 25.0 million ordinary shares of Pubco, which, at an implied value of $10.00 per share, would have a $250 million equity valuation, before fees and expenses. At the closing of the business combination, each outstanding share of Columbus that has not been redeemed by its public shareholders in accordance with its organizational documents will convert into one share of Pubco, and every 7 Columbus rights will be eligible to convert into one share of Pubco. In connection with the business combination, WISeKey and SEALSQ are expected to make investments resulting in no less than $10.0 million in cash to WISeSat. The Business Combination Agreement contemplates that WISeKey may, at its election, distribute immediately after the closing of the business combination up to 10% of the Pubco shares that it receives to its shareholders.
2
At the closing of the business combination, any cash remaining in Columbus’s trust account after paying redeeming public shareholders of Columbus, along with any cash provided by WISeKey or SEALSQ, after payment of transactions fees and expenses and other liabilities of Columbus, will be contributed to Pubco to support ongoing operations and planned commercialization efforts. The Business Combination Agreement and related transactions have been unanimously approved by the boards of directors of WISeKey, WISeSat and Columbus, and are subject to approval by the shareholders of Columbus and other customary closing conditions. WISeKey, as the sole holder of WISeSat shares, has also approved the Business Combination Agreement and related transactions.
A more detailed description of the terms of the Business Combination Agreement and related transactions and a copy of the Business Combination Agreement will be included in a Current Report on Form 8-K to be filed by Columbus and in a Current Report on Form 6-K to be filed by WISeKey with the U.S. Securities and Exchange Commission (“SEC”). In connection with the transaction, Pubco will file a registration statement for its securities (which will contain a proxy statement of Colombus) with the SEC.
This press release shall not constitute an offer to sell or the solicitation of an offer to buy any of the securities described herein, nor shall there be any sale of these securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.
