This prospectus supplement relates to the prospectus dated February 17, 2026 (the "Prospectus"), forming part of our Registration Statement on Form S-1 (Registration No. 333-289952), which was declared effective by the Securities and Exchange Commission (the "SEC") on February 17, 2026. The Prospectus relates to the offer and resale, from time to time, by the selling stockholder identified therein (or its permitted transferees) of up to 10,200,000 shares of our common stock, par value $0.01 per share (the "Common Stock"), issuable under the Standby Equity Purchase Agreement dated July 25, 2025 (as amended), by and between VisionWave Holdings, Inc. (the "Company," "we," "us," or "our") and YA II PN, Ltd. (the "Selling Stockholder").

**Recent Developments**

**Execution of Definitive Agreement for Acquisition of Controlling Interest in C.M. Composite Materials Ltd.**

On February 20, 2026 (the "Effective Date"), the Company, entered into two related definitive agreements in connection with a strategic investment and acquisition transaction involving C.M. Composite Materials Ltd., an Israeli corporation with registration number 513931980 (the "Target Company"): (i) an Investment and Share Purchase Agreement (the "Share Purchase Agreement"), dated as of February 20, 2026, by and among the Company (as Buyer), Matania (Mati) Moskovich (as Seller), and the Target Company (solely for purposes of acknowledgment and certain covenants); and (ii) a Loan Agreement (the "Loan Agreement"), dated as of February 20, 2026, by and between the Company (as Lender) and the Target Company (as Borrower).

The Share Purchase Agreement and Loan Agreement have been filed on February 23, 2026 as exhibits to a Current Report on Form 8-K.

Pursuant to the Share Purchase Agreement, the Company agreed to acquire from the Seller 10.2 ordinary shares of the Target Company (the "Purchased Shares"), representing 51% of the issued and outstanding ordinary shares of the Target Company (which has 20 outstanding ordinary shares out of 30,000 authorized ordinary shares, par value 0.1 NIS per share). In consideration therefor, the Company agreed to issue to the Seller 250,000 shares of the Company's common stock, $0.01 par value per share (the "Buyer Shares"), valued at $2,500,000 based on the parties' agreement.

The transaction is structured as a private placement exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), and/or Rule 506 of Regulation D promulgated thereunder. The Seller was granted certain registration rights with respect to the Buyer Shares. The Company has also agreed to provide loans to the Target Company as additional consideration under the Share Purchase Agreement.

The Loan Agreement provides for a secured loan facility in an aggregate principal amount of up to $5,000,000 (the "Commitment"). The Company is obligated to make an initial advance of up to $1,500,000 within ten (10) Business Days following the Effective Date (subject to satisfaction of conditions precedent), to be used for general working capital purposes consistent with the Target Company's ordinary course of business. Subsequent advances of the remaining up to $3,500,000 may be made in one or more tranches upon mutual written agreement of the parties, solely for working capital or the establishment and operation of a new facility outside Israel, with each tranche subject to the Company's reasonable approval and minimum amounts (generally not less than $250,000 unless otherwise agreed). Proceeds of subsequent advances are to be used exclusively to operate, develop, certify, market, and commercialize the Target Company's technologies and products in global markets, including the United States. This Loan Agreement expands upon the Company's prior financial support to the Target Company including advances disclosed in previous Current Reports on Form 8-K. On February 5, 2026, the Company advanced $500,000 to Target Company, on January 22, 2026 the Company advanced $200,000 to Target Company and on December 26, 2025 the Company advanced $398,345 to Target Company. The advances were made pursuant to a promissory note with a 24-month maturity, bearing no interest unless an event of default occurs (then at 5% per annum or the lower legal maximum), prepayable without penalty, and not contingent on any acquisition or strategic transaction.

Any loan pursuant to the Loan Agreement will bear simple interest at 12% per annum (or such lower rate as mutually agreed in writing, but not exceeding prevailing market rates for similar loans as determined in good faith by the Company), calculated on a 360-day year basis for actual days elapsed. The loan will mature three (3) years after the Effective Date. The obligations under the Loan Agreement are secured by a first-priority security interest in substantially all assets of the Target Company (including accounts, inventory, equipment, general intangibles, intellectual property, and proceeds thereof). The Loan Agreement is evidenced by a promissory note substantially in the form attached as Exhibit A thereto.

On February 23, 2026, the Company filed a Current Report on Form 8-K disclosing the execution of the Share Purchase Agreement and Loan Agreement. The disclosure in this prospectus supplement supplements and updates the information contained in that Form 8-K.

**Risks Associated with the Transaction**

The acquisition involves significant risks, including:

● Failure to satisfy closing conditions or obtain necessary approvals, resulting in termination of the Definitive Agreement.

● Integration challenges, which may not yield anticipated efficiencies or could incur unexpected costs or delays.

● Geopolitical, regulatory, and export control risks associated with defense-related manufacturing in Israel and potential expansion into other jurisdictions, including potential requirements for prior approval from the Israeli Ministry of Defense or other regulatory bodies which, if not obtained, could delay or prevent the closing of the transaction.

● Currency fluctuations (NIS/USD), purchase accounting impacts, and variability in Target Company's historical financials upon consolidation.

● Dilutive effects if the transaction involves issuance of additional equity.

These risks, and others, are in addition to the risks described in the "Risk Factors" section of the Prospectus and in our periodic reports filed with the SEC.
