EigenQ and Silicon Valley Acquisition Corp. Announce Approximately $45M Committed Financing to Support EigenQ’s Commercialization

Austin, Texas – September 18, 2026 – EigenQ, Inc. (“EigenQ”), an applied quantum technology company building the trusted infrastructure for the Quantum Era, and Silicon Valley Acquisition Corp. (“SVAQ”) (Nasdaq: SVAQ), a publicly traded special purpose acquisition company, today announced that EigenQ has entered into a securities purchase agreement (the “Purchase Agreement”) with an institutional investor providing financing to support EigenQ’s commercialization plans.

The financing is comprised of approximately $45 million in the form of a convertible note, of which approximately $22.5 million was funded upfront with the remaining expected to fund at completion of the previously announced Business Combination between EigenQ and SVAQ. EigenQ expects to use the net proceeds of the financing to accelerate commercialization of its quantum-safe security portfolio, expand delivery capacity alongside its OEM and channel partners, continue R&D across quantum security, communications, networking and sensing, and for working capital and general corporate purposes.

Dr. José R. Rosas-Bustos, Chief Executive Officer of EigenQ. “Today’s announcement is a major milestone for EigenQ. It represents an important endorsement of what we have already built and our ability to bring together exceptional partners and institutions to participate in our story. This investment accelerates our mission to offer quantum solutions that can add significant value to companies in the post quantum world.”

Dr. Jesse Van Griensven Thé, Chairman of EigenQ, added, “We believe that our key strategic decisions of undertaking a capital-light approach through partnerships and building sustainable operations with optimal capital deployment have led us to our first institutional capital raise. We are excited to bring the EigenQ story to the public markets as this financing full funds us through cash flow breakeven.”

Dan Nash, Chief Executive Officer of SVAQ, said, “We believe that the quantum technology market represents a generational opportunity and EigenQ is well positioned to capture it. We remain excited to partner with EigenQ’s exceptional leadership team and the new investor as EigenQ moves towards the public markets.”
