Underwriting Agreement

On January 26, 2026, Arbe Robotics Ltd. (“Arbe” or the “Company”), commenced an underwritten registered direct offering (the “Offering”) of 13,225,000 (the “Firm Shares”) ordinary shares, par value NIS 0.000216 per share, of the Company (the “Ordinary Shares”) including 1,725,000 Ordinary Shares issued pursuant to the full exercise of the over-allotment option (the “Optional Shares” and, together with the Firm Shares, the “Shares”). The public offer price for each Share was $1.40.

Canaccord Genuity acted as the sole bookrunner for the Offering, with Roth Capital Partners and WestPark Capital acting as co-managers for the Offering.

The gross proceeds from the Offering, before deducting underwriting discounts and commissions and offering expenses payable by the Company, described in more detail below, were approximately $18.5 million. The Company intends to use the net proceeds from the Offering for working capital and general corporate purposes. The Offering is anticipated to close on January 27, 2026 (the “Closing”).

In Connection with the Offering, the Company entered into an underwriting agreement (the “Underwriting Agreement”) with Canaccord Genuity LLC as representative (the “Representative”) of the underwriters named therein. Pursuant to the Underwriting Agreement, the Company has agreed not to issue, enter into any agreement to issue or announce the issuance or proposed issuance of any Ordinary Shares or any securities convertible into, or exercisable or exchangeable for, Ordinary Shares, including the filing of a registration statement with the Securities and Exchange Commission (“SEC”) in respect thereof, subject to certain exceptions in each instance, for a period of ninety (90) days following the Closing.

The Underwriting Agreement contains customary representations, warranties, covenants and agreements by the Company, indemnification obligations of the Company, including for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), other obligations of the parties and termination provisions. The representations, warranties and covenants contained in the Underwriting Agreement were made only for the purposes of such agreement and as of specific dates, were solely for the benefit of the parties to such agreement and may be subject to limitations agreed upon by the contracting parties.

Pursuant to the Underwriting Agreement, the Company has agreed to pay the underwriters underwriting commissions and discounts equal to 6.0% of the gross proceeds of the Offering, including the additional gross proceeds from the underwriters’ exercise of their option to purchase additional shares, and reimbursement of expenses equal to $125,000.

The Shares were offered by the Company pursuant to a registration statement on Form F-3 (File No. 333-287805) originally filed on June 5, 2025, with the SEC under the Securities Act and declared effective by the SEC on June 13, 2025.
