AUSTIN, Texas and PALO ALTO, Calif., September 28, 2026 -- EigenQ, Inc. and Silicon Valley Acquisition Corp. today announced the public filing with the U.S. Securities and Exchange Commission ("SEC") of a registration statement on Form S-4 (the "Registration Statement") in connection with their previously announced proposed business combination (the "Business Combination").

The Registration Statement includes a preliminary proxy statement/prospectus relating to the proposed Business Combination. The Registration Statement has not yet been declared effective by the SEC, and the information contained therein remains subject to change.

The public filing represents another step toward completion of the proposed Business Combination. Earlier this month, EigenQ announced that it has secured approximately $45 million in a convertible financing, with approximately half of the capital already funded, to support the commercialization of its quantum-safe security portfolio and continue developing quantum products across security, communications, networking and sensing.

Under the terms of the Business Combination Agreement, as amended, SVAQ is expected to domesticate to become a Delaware corporation and, following completion of the Business Combination, be renamed as EigenQ Holdings, Inc. ("PubCo"). EigenQ will survive the merger as a wholly owned subsidiary of PubCo.

SVAQ has applied to list the PubCo Common Stock and PubCo Public Warrants on the Nasdaq Global Market under the proposed ticker symbols "EIGQ" and "EIGQW," respectively, effective upon the closing of the Business Combination. There is no condition to Closing that the PubCo Public Warrants be approved for listing on Nasdaq, and there can be no assurance that the PubCo Public Warrants will be listed on Nasdaq or any other national securities exchange following the Closing. Completion of the Business Combination remains subject to the Registration Statement being declared effective by the SEC, required shareholder approvals, satisfaction of applicable listing requirements and other customary closing conditions. The Business Combination is currently expected to close in the fourth quarter of 2026.

"The public filing of the Registration Statement represents another important milestone toward completing our proposed Business Combination with SVAQ," said Dr. José R. Rosas-Bustos, Chief Executive Officer of EigenQ. "As we continue advancing the transaction, our focus remains on disciplined execution, advancing our technology and commercialization strategy with channel participants, OEMs and customers, and building sustainable long-term value."

Dr. Jesse Van Griensven Thé, Chairman of EigenQ, added: "Our mission is to build the trusted infrastructure that enables governments, enterprises and critical industries to operate securely in the Quantum Era. We believe the proposed Business Combination can provide EigenQ with an expanded platform from which to accelerate innovation, deepen strategic partnerships and advance the commercialization of our foundational quantum technologies. As we move forward, we remain committed to building a more trusted, resilient and quantum-ready digital future."

The Registration Statement, including the preliminary proxy statement/prospectus and additional information regarding the proposed Business Combination, is available through the SEC's website at www.sec.gov. Investors and security holders are urged to read the Registration Statement and the documents incorporated by reference therein carefully and in their entirety because they contain important information about the proposed Business Combination.
