Baozun Announces Second Quarter 2026 Unaudited Financial Results

SHANGHAI, China, August 27, 2026 – Baozun Inc. (Nasdaq: BZUN and HKEX: 9991) (“Baozun”, the “Company” or the “Group”), a leading brand e-commerce solution provider and digital commerce enabler in China, today announced its unaudited financial results for the second quarter ended June 30, 2026.

Mr. Vincent Qiu, Chairman and Chief Executive Officer of Baozun, commented, “We delivered another solid second quarter, with total revenue growing 7% year-over-year and earnings quality continuing to improve with record operating profits in recent years for the second quarter, amid soft consumer sentiment. BEC delivered resilient growth while further strengthening efficiency and profitability. BBM sustained strong brand momentum, led by continued strength at GAP. In addition, we are also encouraged by the early results from our technology innovation and AI-powered automation pilots, which we expect to accelerate across the Group to enhance productivity, streamline operations, and drive further efficiency gains. With both divisions performing well and synergies deepening, we are confident in our ability to create a powerful platform for mutual growth and a more profitable operating model.”

Ms. Catherine Zhu, Chief Financial Officer of Baozun Inc., commented, “Our second-quarter results reflect balanced growth across both divisions, with E-Commerce revenue up 5% and Brand Management revenue up 22% year-over-year. Non-GAAP operating income improved to RMB74 million, driven by continued profitability improvement at BEC and a further narrowing of BBM’s operating loss. Blended gross margin for product sales expanded by 499 basis points year-over-year, while inventory days improved to 112 days from 134 days a year ago, demonstrating our ongoing effectiveness and discipline in inventory turnover management. With strong business momentum and healthy operating efficiency, we remain confident in sustaining this trajectory of high-quality and profitable growth.”

Business Highlights

Baozun e-Commerce, or “BEC”

BEC encompasses our China e-commerce businesses, including brand store operations, customer services, and value-added services covering warehousing and fulfillment, IT and digital marketing. During the second quarter of 2026, total revenue from BEC increased by 4.6% year-over-year, mainly driven by resilient growth in service fee model. BEC’s services revenue grew by 10.0% to RMB1,761.8 million, mainly driven by revenue growth in Digital Marketing and IT solutions.

Baozun Brand Management, or “BBM”

BBM provides holistic brand management, encompassing strategic and tactical positioning, branding and marketing, retail and e-commerce operations, supply chain and logistics, and technology enablement. We aim to leverage our portfolio of technologies to build longer and deeper relationships with brands. During the second quarter of 2026, total revenue from BBM increased by 21.9% year-over-year to RMB485.6 million. We have 184 offline stores under our management at the end of the second quarter of 2026.

Second Quarter 2026 Financial Results

Total net revenues were RMB2,743.0 million (US$404.3 million), an increase of 7.5% from RMB2,552.7 million in the same quarter of last year. The increase in total net revenues was driven by revenue growth in both the Company’s BEC and BBM business lines.

Total product sales revenue was RMB1,025.6 million (US$151.1 million), an increase of 3.2% compared with RMB994.1 million in the same quarter of last year, of which,

Services revenue was RMB1,717.4 million (US$253.1 million), an increase of 10.2% from RMB1,558.6 million in the same quarter of last year. The increase was primarily attributable to double-digit revenue growth in digital marketing and IT solutions.

Total operating expenses were RMB2,679.6 million (US$394.9 million), compared with RMB2,562.0 million in the same quarter of last year.

Income from operations was RMB63.4 million (US$9.3 million), compared with loss from operations of RMB9.4 million in the same quarter of last year. The operating margin was 2.3%, compared with negative 0.4% in the same quarter of last year.

Unrealized investment loss was RMB0.2 million (US$0.03 million), compared with RMB4.0 million in the same quarter of last year. The unrealized investment loss of this quarter was primarily due to the decrease in the trading price of publicly listed companies we invested in.

Fair value change on financial instruments was a gain of RMB0.9 million (US$0.1 million), compared with RMB4.4 million in the same quarter of last year. The fair value change on financial instruments is mainly comprised of the gain recognized from the financial instruments the Company invested in.

The table below provides a summary of the Group’s reportable segment results for the three months ended June 30, 2025 and 2026:

Business Outlook

As the Company continues to leverage technological innovation and AI-powered infrastructure to enhance productivity, it has revised its 2028 annual Non-GAAP income from operations target upward to at least RMB700 million, from RMB550 million. The Company expects to achieve this target primarily through margin expansion in BEC, driven by efficiency and business quality improvements, scale and operating leverage in BBM, and deeper strategic synergies between BEC and BBM. This target is based on the Company’s current expectations, assumptions and business outlook and is subject to significant risks and uncertainties that could cause actual results to differ materially.

Use of Non-GAAP Financial Measures

The Company also uses certain non-GAAP financial measures in evaluating its business. For example, the Company uses non-GAAP income (loss) from operations, non-GAAP net income (loss), non-GAAP net margin, non-GAAP net income (loss) attributable to ordinary shareholders of Baozun and diluted non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS, as supplemental measures to review and assess its financial and operating performance. The presentation of these non-GAAP financial measures is not intended to be considered in isolation, or as a substitute for the financial information prepared and presented in accordance with U.S. GAAP.

The Company defines non-GAAP income (loss) from operations as income (loss) from operations excluding the impact of share-based compensation expenses, amortization of intangible assets resulting from business acquisition, impairment of goodwill and cancelation fees of repurchased. The Company defines non-GAAP net income (loss) as net (loss) income excluding the impact of share-based compensation expenses, amortization of intangible assets resulting from business acquisition, impairment of goodwill and investments, other-than-temporary impairment of equity method investments, cancellation fees of repurchased ADSs, fair value gain on derivative liabilities, loss (gain) on disposal/acquisition of subsidiaries, and unrealized investment loss (gain). The Company defines non-GAAP net income (loss) attributable to ordinary shareholders of Baozun as net income (loss) attributable to ordinary shareholders of Baozun excluding the impact of share-based compensation expenses, amortization of intangible assets resulting from business acquisition, impairment of goodwill and investments, other-than-temporary impairment of equity method investments, cancellation fees of repurchased ADSs, fair value gain on derivative liabilities, loss (gain) on disposal/acquisition of subsidiaries, and unrealized investment loss (gain). The Company defines diluted non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS as non-GAAP net income (loss) attributable to ordinary shareholders of Baozun divided by weighted average number of shares used in calculating net income (loss) per ordinary share multiplied by three.

The Company presents the non-GAAP financial measures because they are used by the Company’s management to evaluate the Company’s financial and operating performance and formulate business plans. Non-GAAP income (loss) from operations, non-GAAP net income (loss), non-GAAP net income (loss) attributable to ordinary shareholders of Baozun and Non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS reflect the Company’s ongoing business operations in a manner that allows more meaningful period-to-period comparisons. The Company believes that the use of the non-GAAP financial measures facilitates investors to understand and evaluate the Company’s current operating performance and future prospects in the same manner as management does, if they so choose. The Company also believes that the non-GAAP financial measures provide useful information to both management and investors by excluding certain expenses, gain/loss and other items that are not expected to result in future cash payments or that are non-recurring in nature or may not be indicative of the Company’s core operating results and business outlook.

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. One of the key limitations of using non-GAAP income (loss) from operations, non-GAAP net income (loss), non-GAAP net income (loss) attributable to ordinary shareholders of Baozun, and non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS is that they do not reflect all items of income and expense that affect the Company’s operations. Further, the non-GAAP measures may differ from the non-GAAP measures used by other companies, including peer companies, potentially limiting the comparability of their financial results to the Company’s. In light of the foregoing limitations, the non-GAAP income (loss) from operations, non-GAAP operating margin, non-GAAP net income (loss), non-GAAP net margin, non-GAAP net income (loss) attributable to ordinary shareholders of Baozun and non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS for the period should not be considered in isolation from or as an alternative to income (loss) from operations, operating margin, net income (loss), net margin, net income (loss) attributable to ordinary shareholders of Baozun and net income (loss) attributable to ordinary shareholders of Baozun per ADS, or other financial measures prepared in accordance with U.S. GAAP.

The Company compensates for these limitations by reconciling the non-GAAP financial measures to the nearest U.S. GAAP performance measures, which should be considered when evaluating the Company’s performance. The Company encourages you to review the Company’s financial information in its entirety and not rely on a single financial measure. For reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures, please see the section of the accompanying tables titled, “Reconciliations of GAAP and Non-GAAP Results.”
