SHANGHAI, February 25, 2026 — Dingdong (Cayman) Limited (the “Company”) (NYSE: DDL), a leading fresh grocery e-commerce company in China, announces that the record date for the purpose of determining the eligibility of the holders of the Class A ordinary shares and the Class B ordinary shares of the Company, par value US$ 0.000002 each (the “Ordinary Shares”), to vote and attend the forthcoming 2026 annual general meeting of the Company (the “AGM”), will be as of the close of business on Monday, March 9, 2026, Shanghai time (the “Ordinary Share Record Date”).

In order to be eligible to vote and attend the AGM, with respect to Ordinary Shares registered on the Company’s principal share register in the Cayman Islands, all valid documents for the transfers of shares accompanied by the relevant share certificates must be lodged with the Company’s principal share registrar and transfer office, Maples Fund Services (Cayman) Limited, PO Box 1093, Boundary Hall, Cricket Square, Grand Cayman, KY1-1102, Cayman Islands, no later than 6:00 p.m. on Friday, March 6, 2026, Cayman Islands time (due to the time difference between the Cayman Islands and Shanghai). All persons who are registered holders of the Ordinary Shares on the Ordinary Share Record Date will be entitled to vote and attend the AGM.

Holders of American depositary shares (the “ADSs”) issued by Deutsche Bank Trust Company Americas as the depositary of the ADSs (the “Depositary”), each two representing three Class A ordinary shares of the Company, may attend, but may not vote at, the AGM. The ADS holders as of the close of business on Friday, March 6, 2026, New York time (the “ADS Record Date”, together with the Ordinary Share Record Date, the “Record Date”), after receiving the voting materials from the Depositary, will be able to instruct the Depositary, being the holder of record of the Class A ordinary shares represented by the ADSs, as to how to vote the Class A ordinary shares represented by such ADSs. The Depositary will endeavor, to the extent practicable and legally permissible, to vote or cause to be voted at the AGM the Class A ordinary shares represented by the ADSs in accordance with the instructions that it has properly and timely received from the ADS holders. Please be aware that, because of the time difference between Shanghai and New York, any ADS holders that cancel their ADSs in exchange for Class A ordinary shares on Friday, March 6, 2026, New York time will no longer be ADS holders with respect to such canceled ADSs as of the ADS Record Date and will not be able to instruct the Depositary as to how to vote the Class A ordinary shares represented by such canceled ADSs as described above; such ADS holders will also not be holders of the Class A ordinary shares represented by such canceled ADSs as of the Ordinary Share Record Date for the purpose of determining the eligibility to attend and vote at the AGM.
