Ms. Qian continued, “At the same time we have substantially reduced our store operating loss as a percentage of net revenues as a result of benefits of scale and increased bargaining power, operating efficiency from technology, and higher store throughput, and we are on track to reach our store level break-even point during the third quarter of 2019.”

“Furthermore, we opened 593 net new Luckin stores during the quarter, providing enhanced convenience to our customers, and strategically launched our new freshly-brewed tea drinks ‘Luckin Tea’ to capture different consumption moments and benefit from strong demand for freshly-brewed tea drinks in China. We also strengthened our supply chain and continued to invest in our brand and our technology. Finally, we remain on track to become the largest coffee network in China in terms of number of stores by the end of 2019,” concluded Ms. Qian.

SECOND QUARTER 2019 UNAUDITED FINANCIAL RESULTS

Total net revenues were RMB909.1 million (US$132.4 million) in the second quarter, representing an increase of 648.2% from RMB121.5 million in the second quarter of 2018. Net revenues growth was primarily driven by a significant increase in the number of transacting customers, an increase in effective selling prices, and the number of products sold.

·                  Net revenues from freshly brewed drinks were RMB659.2 million (US$96.0 million), representing 72.5% of total net revenues in the second quarter of 2019, compared to RMB100.5 million, or 82.7% of total net revenues, in the second quarter of 2018.

·                  Net revenues from other products were RMB210.8 million (US$30.7 million), representing 23.2% of total net revenues in the second quarter of 2019, compared to RMB8.4 million, or 7.0% of total net revenues, in the second quarter of 2018.

·                  Other revenues, which mainly include delivery fees, were RMB39.1 million (US$5.7 million), representing 4.3% of total net revenues in the second quarter of 2019, compared to RMB12.5 million, or 10.3% of total net revenues, in the second quarter of 2018.

Total operating expenses were RMB1,598.8 million (US$232.9 million), representing an increase of 243.9% from RMB465.0 million in the second quarter of 2018. The increase in operating expenses was in line with business expansion. Meanwhile, operating expenses as a percentage of net revenues decreased to 175.9% in the second quarter of 2019 from 382.7% in the second quarter of 2018, mainly driven by increased economies of scale and the Company’s technology-driven operations.

·                  Cost of materials were RMB465.8 million (US$67.9 million), representing an increase of 514.8% from RMB75.8 million in the second quarter of 2018, in line with the increase in sales of products.

·                  Store rental and other operating costs were RMB371.5 million (US$54.1 million), representing an increase of 271.7% from RMB99.9 million in the second quarter of 2018, mainly due to increases in the number of stores and headcount.

2

·                  Depreciation expenses were RMB88.5 million (US$12.9 million), representing an increase of 491.0% from RMB15.0 million in the second quarter of 2018, mainly due to increases in depreciation of leasehold improvements and purchases of operating equipment.

·                  Sales and marketing expenses were RMB390.1 million (US$56.8 million), representing an increase of 119.1% from RMB178.1 million in the second quarter of 2018, mainly due to increases in advertising expenses and delivery expenses as the Company launched new marketing initiatives and entered into new cities. Furthermore, free product promotion expenses increased in line with the growth of new transacting customers.

·                  General and administrative expenses were RMB265.8 million (US$38.7 million), representing an increase of 254.8% from RMB74.9 million in the second quarter of 2018. The increase in general and administrative expenses was mainly driven by business expansion, costs related to the Company’s Initial Public Offering (“IPO”), and share-based compensation to senior management.

·                  Store preopening and other expenses were RMB17.2 million (US$2.5 million), representing a decrease of 19.4% from RMB21.3 million in the second quarter of 2018, mainly due to decreased rental costs before opening as a result of improved efficiency for new store openings.

Operating loss was RMB689.7 million (US$100.5 million) compared to RMB343.4 million in the second quarter of 2018. Non-GAAP operating loss was RMB619.3 million (US$90.2 million) compared to RMB343.4 million in the second quarter of 2018. For more information on non-GAAP financial measures, please see the section of “Use of Non-GAAP Financial Measures” and the table captioned “Reconciliation of Non-GAAP Measures to the Most Directly Comparable GAAP Measures” set forth at the end of this press release.

Net loss was RMB681.3 million (US$99.2 million) compared to RMB333.0 million in the second quarter of 2018. Non-GAAP net loss was RMB610.8 million (US$89.0 million) compared to RMB333.0 million in the second quarter of 2018.

Basic and diluted net loss per ADS was RMB6.56 (US$0.96) compared to a loss of RMB23.04 in the second quarter of 2018. Non-GAAP basic and diluted net loss per ADS was RMB3.28 (US$0.48) compared to a loss of RMB6.80 in the second quarter of 2018.

Net cash used in operating activities was RMB375.2 million (US$54.7 million) compared to RMB196.0 million in the second quarter of 2018. The increase was primarily driven by an increase in operating expenses as a result of expansion of the Company’s business operations.

Cash and cash equivalents and short-term investments were RMB6,051.2 million (US$881.5 million) as of June 30, 2019, compared to RMB1,761.0 million as of December 31, 2018. The increase was primarily driven by the net proceeds of US$158.8 million from the issuance of Series B-1 convertible redeemable preferred shares in April 2019 to certain investors and the net proceeds of US$657.2 million from the IPO and the concurrent private placement.

USE OF NON-GAAP FINANCIAL MEASURES

In evaluating the business, the Company considers and uses non-GAAP measures, such as non-GAAP operating loss, non-GAAP net loss, non-GAAP basic and diluted net loss per ADS, as supplemental measures to review and assess 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 accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Company defines non-GAAP operating loss as operating loss excluding share-based compensation expenses. The Company defines non-GAAP net loss as net loss excluding share-based compensation expenses and change in fair value of warrant liability.  The Company defines non-GAAP basic and diluted net loss per ADS as non-GAAP net loss divided by weighted average number of basic and diluted ADS.

5

The Company presents these non-GAAP financial measures because they are used by management to evaluate operating performance and formulate business plans. 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 is a non-cash charge. The Company also believes that the non-GAAP financial measures could provide further information about the Company’s results of operations, enhance the overall understanding of the Company’s past performance and future prospects.

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. The Company’s non-GAAP financial measures do not reflect all items of income and expense that affect the Company’s operations and do not represent the residual cash flow available for discretionary expenditures. Further, these non-GAAP measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited. The Company compensates for these limitations by reconciling the non-GAAP financial measures to the nearest U.S. GAAP performance measure, all of which should be considered when evaluating performance. The Company encourages you to review the Company’s financial information in its entirety and not rely on a single financial measure.

For more information on the non-GAAP financial measures, please see the table captioned “Reconciliation of Non-GAAP Measures to the Most Directly Comparable GAAP Measures” set forth at the end of this press release.
