INFORMATION CONTAINED IN THIS CURRENT REPORT ON FORM 6-K

On December 8, 2025, Arbe Robotics Ltd. (the "Company") issued a press release announcing information regarding a proposal to extend to December 31, 2026 the deadline for meeting the conditions under its series A convertible bonds for the release of the proceeds raised from the issuance of the convertibles bonds which proceeds are held by the trustee of such bonds. This trustee published a notice regarding a meeting of the bondholders (without physical convening) to be held on December 16, 2025, to vote on the proposed extension and updated terms, which include a reduction of the interest rate of the bonds from 6.5% to 4.35% effective January 1, 2026. The bonds would remain convertible into the Company's ordinary shares at a conversion price of ILS 9.53 (approximately \$2.95) per share. In addition, if the amendment is approved by the bondholders, the Company is considering the issuance of additional bonds of the same series increasing the principal amount of outstanding bonds to up to \$20 million. As of the date of this press release, the principal amount of outstanding bonds is approximately \$8.5 million.

The decision to seek an extension follows, among others, recent developments as a result of which the Company does not expect to secure the potential strategic program award with a European OEM in the near future. The Company continues to stand by its recently announced 2026 goals.

The press release is furnished as Exhibit 99.1 to this Current Report on Form 6-K.

Arbe Announces Proposed Extension of Convertible Debenture Milestones

Tel Aviv, Israel, December 8, 2025 - Arbe Robotics Ltd. (Nasdaq: ARBE) (TASE: ARBE) ("Arbe" or the "Company"), a global leader in perception radar solutions, today announced that, subject to approval of the bondholders, it proposes to extend to December 31, 2026 the deadline for meeting the conditions under its series A convertible bonds for the release of the proceeds raised from the issuance of the convertible bonds which proceeds are held by the trustee. Under the present terms of the bonds, if the conditions are not met by December 31, 2025, the Company will be required to effect an early redemption of those bonds which have not been converted.

Earlier today, the trustee published a notice regarding a meeting of the bondholders (without physical convening) to be held on December 16, 2025, to vote on the proposed extension and updated terms, which include a reduction of the interest rate of the bonds from 6.5% to 4.35% effective January 1, 2026. The bonds would remain convertible into Arbe's ordinary shares at a conversion price of ILS 9.53 (approximately \$2.95) per share. In addition, if the amendment is approved by the bondholders, the Company is considering the issuance of additional bonds of the same series increasing the principal amount of outstanding bonds to up to \$20 million. As of the date of this press release, the principal amount of outstanding bonds is approximately \$8.5 million. The Company's board of directors has the discretion to determine whether to issue additional bonds and, if it approves the issuance, the amount and terms of any additional bonds which the Company may issue.

The three conditions under these series A convertible bonds for the release of the funds by the trustee are:

• The Company wins a tender or contract to supply its products as a single supplier of chips of imaging radar (directly or through one of the international Tier 1 manufacturers) to one of ten named major automobile manufacturers.
• The average closing trading price of Arbe's ordinary shares on Nasdaq is not less than \$3.10 per share during 30 consecutive trading days, and the average combined trading volume on Nasdaq and TASE during such 30 trading days is at least 300,000 shares per day.
• The closing price of the Company's ordinary shares on Nasdaq on the date the Company presents to the trustee the documentation confirming the fulfillment of the abovementioned conditions precedent, is not less than \$3.10.

The decision to seek an extension follows, among others, recent developments as a result of which Arbe does not expect to secure the potential strategic program award with a European OEM in the near future. The Company continues to stand by its recently announced 2026 goals.
