INFORMATION CONTAINED IN THIS CURRENT REPORT ON FORM 6-K

Private Placement of Series A Convertible Bonds

Arbe Robotics Ltd. (the “Company”), announced today, that on December 23, 2025, the Company accepted commitments from Israeli accredited investors, to participate in a private placement (the “Private Placement”) of NIS 57,600,000 par value, of its Convertible Series A Bonds (the “Additional Series A Convertible Bonds”), at a price of NIS 0.872 per each NIS 1.0 par value of the Additional Series A Convertible Bonds, resulting in aggregate proceeds in the offering of NIS 50,227,200 (equal to approximately USD 15.7 million) to be held in escrow for the benefit of the Company. On December 29, 2025, the Private Placement was completed, and following its completion, the aggregate outstanding par value of the Company’s Series A Convertible Bonds is NIS 89,137,816 par value, and the total amount of proceeds held in escrow is approximately USD 24.3 million.

The Additional Series A Convertible Bonds have identical terms to the existing Series A Convertible Bonds of the Company as amended, and they are considered as one series together with the existing Series A Convertible Bonds. Release from escrow of these bonds is also under the same terms as the existing Series A Convertible Bonds. For more information see Note 9 of the audited financial statements of the Company for the period ending December 31, 2024, as filed on the Company Annual Report on Form 20-F, submitted to the U.S. Securities and Exchange Commission (“SEC”) on March 28, 2025 and see also the Current Report on Form 6-K filed with the SEC on December 22, 2025.

The approval of the Company’s board of directors to carry out the Private Placement was received on December 23, 2025. The issuance of the Additional Series A Convertible Bonds was subject to the receipt of an approval from the Tel Aviv Stock Exchange for the listing of the Additional Series A Convertible Bonds for trading on the Tel Aviv Stock Exchange, which was received on December 24, 2025. Resales of the Additional Series A Convertible Bonds will be restricted on the Tel Aviv Stock Exchange under applicable Israeli securities laws. The Company intends to file a prospectus with the SEC relating to registration for resale of the ordinary shares of the Company issuable upon conversion of the Additional Series A Convertible Bonds.

The Private Placement was made to Israeli accredited investors only and not to U.S. Persons, pursuant to an exemption provided by Regulation S, promulgated under the U.S. Securities Act of 1933, as amended, or the Securities Act. The Additional Series A Convertible Bonds will not be registered under the Securities Act and will not be offered or sold in the United States without registration or applicable exemption from the registration requirements according to the Securities Act.

Nothing in this report constitutes an offer to sell or the solicitation of an offer to buy the Company’s securities.

On December 30, 2025, the Company issued a press release regarding the Private Placement. The press release is furnished as Exhibit 99.1 to this Current Report on Form 6-K.

The information in this Current Report on Form 6-K, including in Exhibit 99.1 hereto, is incorporated by reference in any registration statement on Form F-3 or Form S-8 that incorporates by reference material filed by the Company with the SEC.
