The public submission marks another step forward towards the completion of the business merger previously announced.

Austin, Texas, and Palo Alto, California, September 28th / PRNewswire / —— EigenQ, Inc. (“EigenQ” or “the Company”) and Sil Token Issuer n Valley Acquisition Corp (Nasdaq ticker: SVAQ, commonly referred to as “SVAQ”) announced today that they have submitted a Registration Statement (the “Registration Statement”) to the U.S. Securities and Exchange Commission (“SEC”) regarding the previously announced proposed business merger.

This registration statement contains a preliminary prospectus related to the proposed business merger. The registration statement has not yet been declared effective by SEC, and the information contained therein may still change.

This public submission is another step towards completing the proposed business merger. Earlier this month, EigenQ announced that it had secured approximately $45 million in convertible financing, of which about half of the funds have already been received to support the commercialization of its quantum security product portfolio and to continue developing quantum products in the areas of security, communications, networking, and sensing.

According to the revised terms of the business merger agreement, SVAQ is expected to complete the company registration process and become a Delaware corporation, and will be renamed EigenQ Holdings, Inc ("PubCo"). EigenQ will continue to exist as a wholly-owned subsidiary of PubCo after the merger.

SVAQ has applied to list PubCo common shares and PubCo public warrants on the NASDAQ Global Market under the proposed codes “EIGQ” and “EIGQW” respectively, with plans for this to take effect upon completion of the business merger. The approval of the PubCo public warrants for listing on NASDAQ is not a condition for the completion of the transaction, nor does it guarantee that such warrants will be listed on NASDAQ or any other national securities exchange after the transaction is completed. The completion of the business merger still depends on the registration statement being declared effective by SEC, obtaining the required shareholder approvals, meeting the applicable listing requirements, and other customary delivery conditions. It is currently anticipated that the business merger will be completed in the fourth quarter of 2026.

EigenQ CEO Jos R. Rosas-Bustos, a doctor, stated: "The public submission of the registration declaration represents another important milestone in our proposed business merger with SVAQ. As the transaction progresses, our focus remains on strictly implementing and advancing our technical and commercialization strategies with channel partners, OEM, and customers, as well as on creating sustainable long-term value."

EigenQ Chairman Jesse Van Griensven Th É, Ph.D., added: "Our mission is to build reliable infrastructure that enables governments, enterprises, and key industries to operate securely in the quantum era. We believe that the proposed business merger will provide a larger platform for EigenQ to accelerate innovation, deepen strategic cooperation, and advance the commercialization of our foundational quantum technologies. As we move forward, we remain committed to creating a more trustworthy, resilient digital future ready for the quantum era."

Registration statements, including preliminary proxy agreements/prospectuses, as well as more information regarding the proposed business merger, can be obtained through the SEC website www.sec.gov. Investors and security holders are urged to read the registration statements and the documents incorporated therein carefully and thoroughly, as they contain important information regarding the proposed business merger.
