SHANGHAI, China, March 19, 2024 – ZKH Group Limited (“ZKH” or the “Company”) (NYSE: ZKH), a leading maintenance, repair and operations (“MRO”) procurement service platform in China, today announced its unaudited financial results for the fourth quarter and fiscal year ended December 31, 2023.

Fourth Quarter and Fiscal Year 2023 Operational and Financial Highlights

Mr. Eric Long Chen, Chairman and Chief Executive Officer of ZKH, stated, “Despite a challenging macro environment, we ended 2023 with solid growth, an improved gross margin, reduced losses, and, importantly, profitability in the fourth quarter, demonstrating the resilience and continued growth of the MRO industry and our strong execution to drive our business forward. We have invested and strengthened our advantages in (i) product capabilities through product category expansion and product line extension, (ii) client coverage and servicing capabilities by optimizing sales team’s structure, and (iii) digitalization and artificial intelligence capabilities by integrating our industry know-how, data assets, and IT talents. As we look ahead to 2024, brimming with both challenges and opportunities, we will continue to invest, refine, and optimize our operations to propel long-term growth. In addition, we are aiming to officially launch our overseas business in the United States in the second half of 2024.”

1 GMV is the total transaction value of orders placed on the Company’s platform and shipped to customers, excluding taxes, net of the returned amount.

2 Net revenue under the marketplace model is recognized on a net basis. Therefore, a higher proportion of GMV generated by the marketplace model tends to increase the difference in growth rate between GMV and net revenue. The proportion of GMV generated by the marketplace model was 18.6% and 15.4% for the fourth quarter of 2022 and for the fiscal year of 2022, and 27.6% for fourth quarter of 2023 and 24.8% for the fiscal year of 2023, respectively.

3 Non-GAAP EBITDA is defined as profit/(loss) before interest expenses, income tax expenses/(benefits) and depreciation and amortization expenses.

4 Non-GAAP adjusted net (loss)/profit is defined as net (loss)/profit excluding share-based compensation expenses and interest expenses due to the issuance of Series F Convertible Notes, which have been fully converted into Series F preferred shares without payment of interest.

Mr. Max Chun Chiu Lai, Chief Financial Officer of ZKH, added, “We are delighted with our fourth quarter operational and financial performance, which enabled us to finish 2023 on a strong note, especially as we mark our first quarter as a public company. Powered by our growth from both the ZKH Platform and the GBB Platform, our full-year GMV increased by 18.2% year over year, compared with an increase of 9.2% in 2022. Concurrently, we demonstrated a clear path to profitability, with gross margin improving by 80.8 basis points in 2023 while operating loss margin and adjusted net loss margin narrowing by 366.5 and 476.5 basis points in the fourth quarter, respectively, marking the seventh consecutive quarter of year-over-year improvement. Notably, we achieved profitability in the fourth quarter of 2023, with an adjusted net profit of RMB27.5 million, resulting in a year-over-year decrease of RMB338.6 million in our full-year adjusted net loss.”

Use of Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measures: non-GAAP adjusted net profit/(loss), non-GAAP adjusted net profit/(loss) per ADS, basic and diluted, and non-GAAP EBITDA. The non-GAAP financial measures should not be considered in isolation from or construed as alternatives to their most directly comparable financial measures prepared in accordance with accounting principles generally accepted in the United States of America. Investors are encouraged to review the historical non-GAAP financial measures in reconciliation to their most directly comparable GAAP financial measures.

The Company defines non-GAAP adjusted net profit/(loss) for a specific period as net profit/(loss) in the same period excluding share-based compensation expenses and interest expense due to the issuance of Series F Convertible Notes, which have been fully converted into Series F preferred shares without payment of interests. The Company defines non-GAAP EBITDA as profit/(loss) before interest expenses, income tax expenses/(benefits) and depreciation and amortization expenses. Non-GAAP adjusted net profit/(loss) per ADS is calculated by dividing adjusted net profit/(loss) attributable to the Company’s ordinary shareholders by the weighted average number of ordinary shares outstanding during the periods and then multiplied by 35.

The Company presents these non-GAAP financial measures because they are used by the management to evaluate the Company’s operating performance and formulate business plans. The Company believes that these non-GAAP financial measures help identify underlying trends in its business that could otherwise be distorted by the effect of certain expenses that are included in net profit/(loss) and certain expenses that are not expected to result in future cash payments or that are non-recurring in nature. The Company also believes that the use of these non-GAAP financial measures facilitates investors’ assessment of its operating performance, enhances the overall understanding of its past performance and future prospects and allows for greater visibility with respect to key metrics used by the management in financial and operational decision making.

The non-GAAP financial measures have material limitations as analytical metrics and may not be calculated in the same manner by all companies. The Company's non-GAAP financial measures do not include all income and expense items that affect the Company’s operations. They may not be comparable to other similarly titled measures used by other companies. In light of the foregoing limitations, you should not consider the non-GAAP financial measures as substitutes for, or superior to, their most directly comparable financial measures prepared in accordance with GAAP. The Company encourages investors and others to review its financial information in its entirety and not rely on a single financial measure.

For more information on these non-GAAP financial measures, please see the table captioned “Reconciliations of Non-GAAP Results” set forth at the end of this press release.
