Silicon Valley Acquisition Corp. (NASDAQ:SVAQ), a special purpose acquisition company listed on Nasdaq under the symbol SVAQ, announced on September 28, 2026 that a registration statement on Form S-4 has been publicly filed for its proposed business combination with EigenQ, Inc., a quantum technology company. The combination was announced on June 17, 2026. The Form S-4 is the document through which shareholders will be asked to vote on the deal, so its filing starts the approval process. The company reported the announcement in a Form 8-K designated under Rule 425 with a press release attached as Exhibit 99.1.

What the Announcement Says

Under the plan, Silicon Valley Acquisition Corp. will domesticate to Delaware and be renamed EigenQ Holdings, Inc., referred to in the release as PubCo. The company says the shares and public warrants are expected to be listed on the Nasdaq Global Market under the symbols EIGQ and EIGQW. The press release also warns that there is no condition to closing that the PubCo public warrants be approved for listing on Nasdaq, and that there can be no assurance the warrants will be listed on Nasdaq or any other national securities exchange after closing.

The parties expect the transaction to close in the fourth quarter of 2026, subject to the SEC declaring the registration statement effective, shareholder approvals and satisfaction of listing requirements. Dr. José R. Rosas-Bustos, EigenQ's Chief Executive Officer, is quoted as saying, "The public filing of the Registration Statement represents another important milestone toward completing our proposed Business Combination with SVAQ." The press release does not disclose the valuation of the transaction or other deal terms.

About EigenQ

The release describes EigenQ as an applied quantum technology company headquartered in Texas that is developing hardware-rooted, quantum-safe trust infrastructure for what it calls the Quantum Era. Its initial commercial focus includes post-quantum cryptography, quantum-derived entropy, hardware-rooted trust, secure identity and cryptographic agility, with planned expansion into quantum AI, communications, networking, sensing and computing. EigenQ says it has secured approximately $45 million in convertible financing, roughly half of which has already been funded, to commercialize its quantum-safe security portfolio and support product development.

Dr. Jesse Van Griensven Thé, EigenQ's Chairman, is quoted as saying, "Our mission is to build the trusted infrastructure that enables governments, enterprises and critical industries to operate securely in the Quantum Era."

The release names Ellenoff Grossman & Schole LLP as legal counsel to EigenQ and Greenberg Traurig, LLP as legal counsel to Silicon Valley Acquisition Corp. Cohen & Company Capital Markets is listed as a financial and capital markets advisor, and Secure Strategy Group, LLC as placement agent. The Blueshirt Group and AUM Media are listed for investor relations for EigenQ and SVAQ respectively.

Why the S-4 Matters

A registration statement on Form S-4 is filed when a business combination involves issuing securities to the target's holders or converting the acquirer's securities, and it typically includes a proxy statement and prospectus. The filing at this stage is not final. The document remains subject to review and may be amended before the SEC declares it effective. The 8-K does not say whether the SEC has commented on the filing, does not provide a shareholder meeting date, and does not describe how many SVAQ shareholders may redeem their shares or how much cash remains in the trust account.

EigenQ Combination Milestones After the Form S-4

The events that determine timing are SEC effectiveness of the Form S-4, the setting of a shareholder meeting, the required approvals and Nasdaq listing requirements. The parties are targeting the fourth quarter of 2026.
