EXPLANATORY NOTE

As previously reported on our Report of Foreign Private Issuer on Form 6-K filed with the Securities and Exchange Commission on July 15, 2026 (the “Original 6-K”), on such date, Robo.ai Inc. (Nasdaq: AIIO) (“Robo.ai” or the “Company”), a UAE-based, U.S.-listed company, entered into a securities purchase agreement with a certain institutional investor (the “Note Investor”) dated as of July 15, 2026 (the “SPA”) pursuant to which the Company agreed to issue and sell to the Buyer a new series of senior convertible notes of the Company in an aggregate original principal amount of up to $37.5 million (the “Notes”). We are filing this amendment to the Original 6-K (the “Amendment”) to update the form of Note furnished as an exhibit thereto as an incorrect form was inadvertently furnished as well as to update the corresponding disclosure regarding the Notes. In addition, we are also updating the Original 6-K to disclose the completion of the initial closing pursuant to the SPA.

This Amendment amends and restates the Original 6-K in its entirety as set forth below.

Entry into a Convertible Note Facility

On July 15, 2026, the Company entered into the SPA with the Note Investor, pursuant to which the Company agreed to issue and sell, and the Note Investor agreed to purchase, in multiple closings pursuant to private placement exemptions under Section 4(a)(2) of the Securities Act of 1933 and Rule 506(b) of Regulation D promulgated thereunder and subject to the satisfaction or waiver of certain closing conditions, a new series of senior convertible notes of the Company in an aggregate original principal amount of up to $37.5 million (the “Notes”). The Notes are convertible into the Company’s Class B ordinary shares, par value $0.002 per share, at a purchase price of US$920 per US$1,000 of principal amount.

The Company will issue and sell to the Note Investor (i) an initial Note in the aggregate principal amount of US$12.5 million (the “Initial Note”) for a purchase price of US$11.5 million in an initial closing, and (ii) a second Note in the aggregate principal amount of US$12.5 million (the “Second Notes”) for a purchase price of US$11.5 million in one or more second closings, subject to the satisfaction or waiver of certain conditions, including the availability of sufficient authorized Class B Ordinary Shares for the reserve of the conversion shares underlying such Notes. On July 17, 2026 the initial closing occurred and we issued the Initial Note.

Additional closings may be initiated by either the Note Investor or the Company, subject to the satisfaction or waiver of certain closing conditions, such as minimum trading liquidity requirements, the effectiveness of an registration statement related to the resale of the Class B ordinary shares issuable upon conversion or otherwise pursuant to the terms of the Notes, limits on outstanding principal from prior tranches, and other customary equity conditions. The Note Investor may waive any such conditions and may elect to initiate a closing at its discretion.

The Notes will mature two years after the applicable issuance dates and bear no interest, except that the Notes will bear interest at a rate of 14% per annum upon the occurrence of any event of default pursuant to the Notes for so long as such event remains uncured. The Notes rank pari passu with all other notes and are senior obligations of the Company. The Initial Notes are and the other Notes will be convertible, in whole or in part at any time after issuance, into Class B ordinary shares of the Company in an amount equal to the quotient of (i) product of the principal being converted and 110%, divided by (ii) the lower of (a) 140% of the closing price on the day prior to the applicable Note issuance date (the “Fixed Conversion Price”), and (b) the greater of (1) 90% of the lowest daily VWAP during the 10 days prior to the conversion date or other date of determination and (2) the Floor Price (as defined in the Notes). The Initial Note has a Fixed Conversion Price of $5.81 and matures on July 17, 2028.

A Note holder will not have the right to convert any portion of a Note, to the extent that, after giving effect to such conversion, the holder (together with certain of its affiliates and other related parties) would beneficially own in excess of 9.99% of the Class B ordinary shares outstanding immediately after giving effect to such conversion (the “Beneficial Ownership Limitation”). A Note holder, upon notice to the Company, may increase or decrease the Beneficial Ownership Limitation, provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the Class B ordinary shares outstanding immediately after giving effect to such conversion. Any increase in the Beneficial Ownership Limitation will not be effective until the sixty-first day after such notice is delivered to the Company.

Pursuant to the SPA, the Company intends to use the net proceeds from the sale of the Notes for general corporate purposes and working capital, and no more than an aggregate of US$1,000,000 may be used for (i) the satisfaction of any indebtedness of the Company or its subsidiaries, (ii) the redemption or repurchase of any securities of the Company or its subsidiaries, or (iii) the settlement of any outstanding litigation.

Pursuant to the SPA, the Company agreed, for a covenant period specified in the SPA, not to issue, offer, sell, or otherwise dispose of, or announce the issuance of, any equity or equity-linked securities, subject to certain exceptions. In addition, the Company agreed, during the covenant period, not to effect or enter into any agreement to effect a subsequent placement involving a variable rate transaction.

Concurrently with the execution of the SPA, the Company and the Note Investor also entered into a registration rights agreement dated July 15. 2026 regarding certain resale registration rights of the Note Investor.

The foregoing description of the Notes, Initial Note, SPA, and registration rights agreement does not purport to be complete and is qualified in its entirety by reference to such agreements or form thereof, copies of which are filed as Exhibit 99.1, 99.2, 99.3, and 99.4, respectively, to this Report of Foreign Private Issuer on Form 6-K and incorporated herein by reference.
