Explanatory Note

On March 24, 2026, U Power Limited, a Cayman Islands exempted company with limited liability (the “Company”), announced on a Form 6-K plans to effectuate a consolidation of all of the Company’s authorized issued and unissued ordinary shares on a 10:1 basis (the “Share Consolidation”) that would take effect at the commencement of trading on March 30, 2026. The Company is postponing the effective date and the updated date for the Share Consolidation will instead be April 1, 2026.

Beginning with the opening of trading on April 1, 2026, the Company’s Class A ordinary shares will trade on a post-Share Consolidation basis on the Nasdaq Capital Market under the same symbol “UCAR,” but under a new CUSIP number of G9520U124. No fractional shares will be issued in connection with the Share Consolidation. Instead, record holders who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the Share Consolidation ratio will automatically be entitled to receive an additional fraction of one share to round up to the next whole share. For those beneficial holders who hold shares through a brokerage firm, the Company intends to round up fractional shares at the participant level. Cash will not be paid for fractional shares.
