Jumei Reports Unaudited First Half 2017 Financial Results

BEIJING, Dec. 29, 2017 (Globe Newswire) -- Jumei International Holding Limited (NYSE:JMEI) ("Jumei" or the "Company"), China's leading online retailer of beauty products, today reported its unaudited financial results for the six months ended June 30, 2017.

First Half 2017 Highlights

l Total net revenues for the first half of 2017 were RMB3.2 billion (US^[1] $466.2 million), a 9.2% decrease from the same period of 2016, primarily due to a 2.8% year-over-year decrease in total orders^[2], partially offset by a 3.1% year-over-year increase in the number of active customers^[3].

l Total net GMV ^[4] was RMB3.6 billion (US$537.0 million), an 8.5% decrease year-over-year, which is primarily due to a decrease in sales from merchandise sales.

l Gross profit as a percentage of net revenues decreased to 23.8% from 27.9% in the same period of 2016. The decrease was primarily due to the increase in sale tax under the regulation of import tax on consumer goods imported through cross-border e-commerce platforms. Gross profit as a percentage of total net GMV decreased to 20.7% from 24.4% in the same period of 2016.

l Net income attributable to Jumei's ordinary shareholders was RMB101.9 million (US$15.0 million), compared with net income attributable to Jumei's ordinary shareholders of RMB141.2 million in the same period of 2016. Net margin attributable to Jumei's ordinary shareholders was 3.2%, compared with 4.1% in the same period of 2016.

l Non-GAAP net income attributable to Jumei's ordinary shareholders^[5] was RMB115.2 million (US$17.0 million), compared with non-GAAP net income attributable to Jumei's ordinary shareholders of RMB163.6 million in the same period of 2016. Non-GAAP net margin attributable to Jumei's ordinary shareholders^[5] was 3.6%, compared with 4.7% in the same period of 2016.

Unaudited First Half 2017 Financial Results

Total net revenues were RMB3.2 billion (US$466.2 million), a decrease of 9.2% from RMB3.5 billion during the same period last year. The decrease was primarily attributable to decrease in the number of total orders. The number of total orders decreased by 2.8% to approximately 34.7 million from 35.7 million in the same period of 2016. The number of active customers increased by 3.1% to approximately 10.1 million from approximately 9.8 million in the same period of 2016.

Gross profit was RMB752.4 million (US$111.0 million), compared with RMB971.4 million in the first half year of 2016. Gross profit as a percentage of net revenues decreased to 23.8% from 27.9% in the same period of 2016. The decrease was primarily due to the increase in sale tax under the regulation of import tax on consumer goods imported through cross-border e-commerce platforms. Gross profit as a percentage of net GMV decreased to 20.7% from 24.4% in the same period of 2016. Gross profit from merchandise sales as a percentage of net GMV of merchandise sales decreased to 24.4% from 28.4% in the same period of 2016.

Total operating expenses were RMB634.6 million (US$93.6 million), a decrease of 25.5% from RMB852.2 million in the first half year of 2016. Operating expenses as a percentage of total net GMV decreased to 17.4% from 21.4% in the same period of 2016.

l Fulfillment expenses were RMB315.0 million (US$46.5 million), a decrease of 28.4% from RMB439.8 million in the same period of 2016. The decrease was primarily due to the combined effect of the increase of efficiency in orders processing and the decrease in the number of orders. Fulfillment expenses as a percentage of total net GMV decreased to 8.7% from 11.1% in the same period of 2016.

l Marketing expenses were RMB153.8 million (US$22.7 million), a decrease of 30.2% from RMB220.5 million in the same period of 2016. The decrease was primarily due to a decrease in use of live streaming promotional videos and a decrease in traditional advertising. Marketing expenses as a percentage of total net GMV was 4.2%, compared with 5.5% in the same period of 2016.

l Technology and content expenses were RMB91.4 million (US$13.5 million), a decrease of 3.9% from RMB95.1 million in the same period of 2016. Technology and content expenses as a percentage of total net GMV slightly increased to 2.5% from 2.4% in the same period of 2016. The decrease was mainly due to a decrease of server rental which were replaced by self-owned servers in order to build up new network infrastructure to enhance efficiency and scalability.

l General and administrative expenses were RMB74.3 million (US$11.0 million), a decrease of 23.3% from RMB96.9 million in the same period of 2016. General and administrative expenses as a percentage of total net GMV decreased to 2.0% from 2.4% in the same period of 2016. The decrease was primarily attributed to greater efficiency in general and administrative efforts.

Income from operations was RMB117.9 million (US$17.4 million), compared with income from operations of RMB119.2 million in the same period of 2016.

Non-GAAP income from operations, which excludes RMB13.3 million (US$2.0 million) in share-based compensation expenses, was RMB131.1 million (US$19.3 million), compared with non-GAAP income from operations of RMB141.6 million in the same period of 2016.

Net income attributable to Jumei's ordinary shareholders was RMB101.9 million (US$15.0 million), compared with net income attributable to Jumei's ordinary shareholders of RMB141.2 million in the same period of 2016. Net margin attributable to Jumei's ordinary shareholders decreased to 3.2% from 4.1% in the same period of 2016. Net income per basic and diluted ADS were RMB0.68 (US$0.10) and RMB0.68 (US$0.10), respectively, compared with net income per basic and diluted ADS RMB0.95 and RMB0.94, respectively, for the same period of 2016.

Non-GAAP net income attributable to Jumei's ordinary shareholders, which excludes share-based compensation expenses, was RMB115.2 million (US$17.0 million), compared with non-GAAP net income attributable to Jumei's ordinary shareholders RMB163.6 million in the same period of 2016. Non-GAAP net margin attributable to Jumei's ordinary shareholders decreased to 3.6% from 4.7% in the same period of 2016. Non-GAAP net income per basic and diluted ADS were RMB0.77 (US$0.11) and RMB0.77 (US$0.11), respectively, compared with non-GAAP net income per basic and diluted ADS of RMB1.10 and RMB1.09, respectively, in the same period of 2016.

Balance Sheet

As of June 30, 2017, the Company had cash and cash equivalents of RMB2.0 billion (US$296.7 million), and short-term investments of RMB906.7 million (US$133.7 million).

Use of Non-GAAP Financial Measures

To supplement the consolidated financial statements presented in accordance with the United States Generally Accepted Accounting Principles ("GAAP"), Jumei uses non-GAAP income from operations, non-GAAP net income attributable to Jumei's ordinary shareholders, non-GAAP net margin attributable to Jumei's ordinary shareholders and non-GAAP net income per ADS attributable to Jumei's ordinary shareholders, by excluding share-based compensation expenses from operating profit and net income attributable to the Company's shareholders, respectively. The Company believes these non-GAAP financial measures are important to help investors understand Jumei's operating and financial performance, compare business trends among different reporting periods on a consistent basis and assess Jumei's core operating results, as they exclude certain expenses that are not expected to result in cash payments. The use of the above non-GAAP financial measures has certain limitations. Share-based compensation expenses have been and will continue to be incurred in the future and are not reflected in the presentation of the non-GAAP financial measures, but should be considered in the overall evaluation of Jumei's results. The Company compensates for these limitations by providing the relevant disclosure of its share-based compensation expenses in the reconciliations to the most directly comparable GAAP financial measures, which should be considered when evaluating Jumei's performance. These non-GAAP financial measures should be considered in addition to financial measures prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, financial measures prepared in accordance with GAAP. Reconciliation of each of these non-GAAP financial measures to the most directly comparable GAAP financial measure is set forth at the end of this release.
