Dingdong (Cayman) Limited Announces Fourth Quarter 2025 Financial Results

SHANGHAI, March 4, 2026 — Dingdong (Cayman) Limited (“Dingdong” or the “Company”) (NYSE: DDL), a leading fresh grocery e-commerce company in China, with advanced supply chain capabilities, today announced its unaudited financial results for the quarter ended December 31, 2025.

Fourth Quarter 2025 Highlights:

Mr. Changlin Liang, Founder and Chief Executive Officer of Dingdong, stated, “As of the fourth quarter of 2025, Dingdong has maintained profitability under non-GAAP standards for thirteen consecutive quarters and under GAAP standards for eight consecutive quarters. Also the Company has delivered year-over-year revenue growth for the eighth consecutive quarter. This consistent top-line expansion, together with the steady delivery of profitability objectives, fully underscores Dingdong’s strategic resilience and strong execution capabilities amid the complex and competitive market environment. It also provides solid fundamentals and strong momentum to advance our long-term strategic initiatives.”

Mr. Song Wang, Chief Financial Officer of Dingdong, stated, “In the fourth quarter of 2025, Dingdong reported revenue of RMB6.24 billion, marking a 5.7% year-on-year growth and maintaining positive growth for eight straight quarters. Non-GAAP net profit reached RMB50.8 million with a 0.8% net profit margin, while GAAP net profit was RMB33.6 million with a 0.5% margin. We had net operating cash inflow of RMB0.20 billion in the fourth quarter of 2025, the tenth consecutive quarter of positive cash flow. By the end of the fourth quarter, after deducting short-term borrowings, our actual cash owned increased to RMB3.14 billion, the tenth consecutive quarter of sustained growth.”

Fourth Quarter 2025 Financial Results

Total revenues were RMB6,242.6 million (US$892.7 million) compared with total revenues of RMB5,905.0 million in the same quarter of 2024, increased by 5.7% year over year, primarily due to the rise of number of orders resulting from rise in the average monthly number of transacting users and higher monthly order frequency, and new opened frontline fulfillment stations with density and market penetration improved in East China. Additionally, our B2B revenue achieved year-over-year growth, with the revenue contribution from overseas B2B operations continuing to increase and posting rapid quarter-over-quarter growth. The increase was offset by the impact of the price decline in CPI for certain major categories in our business, such as pork, in the fourth quarter of 2025.

Total operating costs and expenses were RMB6,252.5 million (US$894.1 million) compared with RMB5,848.0 million in the same quarter of 2024, with a detailed breakdown as below:

Net income from operations was RMB12.0 million (US$1.7 million), compared with net income from operations of RMB61.5 million in the same quarter of 2024.

Non-GAAP income from operations, which is a non-GAAP measure for loss from operations that excludes share-based compensation expenses, was RMB29.1 million (US$4.2 million), compared with Non-GAAP income from operations of RMB86.6 million in the same quarter of 2024.

Net income was RMB33.6 million (US$4.8 million), compared with net income of RMB91.6 million in the same quarter of 2024.

Non-GAAP net income, which is a non-GAAP measure that excludes share-based compensation expenses, was RMB50.8 million (US$7.3 million), compared with non-GAAP net income of RMB116.7 million in the same quarter of 2024. In addition, non-GAAP net income margin, which is the Company’s non-GAAP net income as a percentage of total revenues, was 0.8% compared with 2.0% in the same quarter of 2024.

Basic and diluted net income per share were RMB0.10 (US$0.01) and RMB0.09 (US$0.01), compared with net income per share of RMB0.27 and RMB0.26 in the same quarter of 2024. Non-GAAP net income per share, basic and diluted, were RMB0.15 (US$0.02) and RMB0.14 (US$0.02), compared with RMB0.35 and RMB0.33 in the same quarter of 2024.

Use of Non-GAAP Financial Measures

The Company uses non-GAAP measures, such as non-GAAP net income, non-GAAP net income margin, non-GAAP net income attributable to ordinary shareholders and non-GAAP net income per share, basic and diluted, in evaluating its operating results and for financial and operational decision-making purposes. The Company believes that the non-GAAP financial measures help identify underlying trends in its business by excluding the impact of share-based compensation expenses, which are non-cash charges and do not correlate to any operating activity trends. The Company believes that the non-GAAP financial measures provide useful information about the Company’s results of operations, enhance the overall understanding of the Company’s past performance and future prospects and allow for greater visibility with respect to key metrics used by the Company’s management in its financial and operational decision-making.

The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The non-GAAP financial measures have limitations as analytical tools, and when assessing the Company’s operating performance, cash flows or liquidity, investors should not consider them in isolation, or as a substitute for net loss, cash flows provided by operating activities or other consolidated statements of operations and cash flows data prepared in accordance with U.S. GAAP. The Company’s definition of non-GAAP financial measures may differ from those of industry peers and may not be comparable with their non-GAAP financial measures.

The Company mitigates these limitations by reconciling the non-GAAP financial measures to the most comparable U.S. GAAP performance measures, all of which should be considered when evaluating the Company’s performance.

For more information on the non-GAAP financial measures, please see the table captioned “Unaudited Reconciliation of GAAP and Non-GAAP Results” set forth at the end of this announcement.
