On March 18, 2026, U Power Limited (the “Company”) entered into a Warrant Exchange and Cancellation Agreement (the “Exchange Agreement”) with SABBY VOLATILITY WARRANT MASTER FUND LTD. (the “Holder”).

Pursuant to the Exchange Agreement, the Holder agreed to the full surrender and cancellation of 551,628 ordinary share purchase warrants previously issued to the Holder (the “Warrants”) on July 25, 2025. In connection with such cancellation, all rights under the Warrants, including the price reset mechanisms set forth in Section 3(b) thereof, have been terminated and are of no further force or effect.

In exchange for the cancellation of the Warrants, the Company agreed to issue 3,000,000 Class A ordinary shares, par value $0.0001 per share, to the Holder (the “Exchange Shares”). To facilitate the Holder’s requirement for immediate liquidity, the Company has committed to delivering the initial 500,000 Exchange Shares via the Depository Trust Company’s Deposit/Withdrawal At Custodian (DWAC) system on or before March 18, 2026. After all of the Exchange Shares are issued, the Company will have 7,603,440 Class A ordinary shares and 368,044 Class B ordinary shares issued and outstanding.

The exchange of the Warrants for the Exchange Shares was made in reliance upon the exemption from registration provided by Section 3(a)(9) of the Securities Act of 1933, as amended. No commission or other remuneration was paid or given, directly or indirectly, for soliciting such exchange.

The foregoing description of the Exchange Agreement is qualified in its entirety by reference to the full text of the Exchange Agreement, which is filed as Exhibit 99.1 to this Report on Form 6-K and is incorporated herein by reference.
