1  Adjusted net income/loss (non-GAAP) is defined as net income/loss excluding share-based compensation expenses and change in fair value of a convertible loan.

Dr. Li continued, “In December 2019, our new manufacturing facility at Changzhou commenced operation.  The new facility covers about 75 acres and has a designed capacity of 700,000 units per annum.  We are very excited about the growth perspective of our business and are committed to expand our production capacity to meet the increasing demand.  In January 2020, we attended the Consumer Electronics Show in the U.S. and launched two new products, the RQi-GT, an urban performance electric motorcycle, and the TQi-GT, our first electric three-wheeler.  We are very excited about the enriched product portfolio and look forward to the sustaining growth of our business.”

Fourth Quarter 2019 Financial Results

Revenues were RMB 536.1 million, an increase of 25.4% year over year, due to increased sales volume of 13.5% and increased revenues per e-scooter of 10.5%.

·                  E-scooter sales represented 83.7% of total revenues, while accessories, spare parts sales and service revenues represented 16.3% of total revenues.

·                  Higher e-scooter sales volume was mainly driven by the expanded sales network and enriched product portfolio.

·                  Increased revenues per e-scooter were mainly driven by higher sales in accessories, spare parts and services.

·                  China represented 90.4% of total e-scooter revenues, while international markets represented 9.6% of total e-scooter revenues.

Cost of revenues were RMB 395.9 million, an increase of 7.0% year over year, mainly due to higher e-scooter sales volume.  The cost per e-scooter, defined as cost of revenues divided by the number of e-scooters sold in a specified period, was RMB 3,726, down 5.7% from RMB 3,952 in the fourth quarter 2018 as a result of lower raw material cost and change in product mix.

Gross margin was 26.1%, up substantially from 13.5% in the same period of 2018, mainly due to lower raw material costs, higher sales price and a greater proportion of revenue from accessories and spare parts.

Operating expenses were RMB 94.2 million, an increase of 3.6% from the same period of 2018. Operating expenses as a percentage of revenues was 17.6%, compared with 21.3% in the fourth quarter of 2018.

·                  Selling and marketing expenses were RMB 48.9 million (including RMB 1.6 million of share-based compensation), an increase of 16.9% from RMB 41.8 million in the fourth quarter of 2018.  The increase was mainly due to the increases in depreciation and amortization expense of RMB 3.4 million, product certification fee of RMB 2.6 million, traveling and rental expense of RMB 2.2 million and share-based compensation expense of RMB 1.1 million.  The higher expenses were partially offset by the decrease of staff cost of RMB 3.5 million due to lower bonus.  Selling and marketing expenses as a percentage of revenues was 9.1% compared with 9.8% in the fourth quarter of 2018.

·                  Research and development expenses were RMB 19.1 million (including RMB 1.9 million of share-based compensation), a decrease of 13.6% from RMB 22.1 million in the fourth quarter of 2018, mainly due to the decrease of share-based compensation expenses of RMB 7.3 million.  The lower expenses were partially offset by the increase in staff cost of RMB 2.7 million and design expense of RMB 1.0 million which resulted from the Company’s continued efforts to enhance the research and development capability.  Research and development expenses as a percentage of revenues was 3.6%, compared with 5.2% in the fourth quarter of 2018.

·                  General and administrative expenses were RMB 26.3 million (including RMB 4.1 million of share-based compensation), a decrease of 2.8% from RMB 27.0 million in the fourth quarter of 2018, mainly due to the decrease of share-based compensation expenses of RMB 10.9 million.  The lower expenses were partially offset by the increase of provision for bad debt of RMB 3.7 million, professional fees of RMB 3.2 million and taxes and surcharges of RMB 2.3 million.  General and administrative expenses as a percentage of revenues was 4.9%, compared with 6.3% in the fourth quarter of 2018.

Operating expenses excluding share-based compensation were RMB 86.5 million, increased by 30.8% year over year, and represented 16.1% of revenues, compared with 15.5% in the fourth quarter of 2018.

·                  Selling and marketing expenses excluding share-based compensation were RMB 47.3 million, an increase of 14.5% year over year, and represented 8.8% of revenues, compared with 9.7% in the fourth quarter of 2018.

·                  Research and development expenses excluding share-based compensation were RMB 17.1 million, an increase of 32.9% year over year, and represented 3.2% of revenues, compared with 3.0% in the fourth quarter of 2018.

·                  General and administrative expenses excluding share-based compensation were RMB 22.1 million, an increase of 84.6% year over year, and represented 4.1% of revenues, compared with 2.8% in the fourth quarter of 2018.

Government grants were RMB 13.5 million, increased by 13.4 million from the same period of 2018, mainly consisting of various incentives from local government authorities.

Share-based compensation was RMB 7.8 million, a decrease of RMB 17.0 million from RMB 24.8 million in the same period of last year.  The decline was mainly due to the accelerated vesting of certain restricted ordinary shares in the fourth quarter 2018.

Net income was RMB 60.7 million, an improvement of RMB 92.7 million compared with a net loss of RMB 32.0 million in the fourth quarter of 2018.  The net income margin was 11.3%, compared with a net loss margin of 7.5% in the same period of 2018.

Adjusted net income (non-GAAP) was RMB 68.5 million, compared with an adjusted net loss of RMB 7.2 million in the fourth quarter of 2018.  The adjusted net income margin2 was 12.8%, compared with an adjusted net loss margin of 1.7% in the same period of 2018.

Basic and diluted net income per ADS were RMB 0.81 (US$ 0.12) and RMB 0.79 (US$ 0.11) respectively.

Full Year 2019 Financial Results

Net revenues were RMB 2,076.3 million, an increase of 40.5%, mainly driven by increases in e-scooter sales volume of 24.1% and net revenues per e-scooter of 13.2%.  China represented 85.1% of net revenues from e-scooter sales, and overseas markets represented 14.9%.

2  Adjusted net income/loss margin is defined as adjusted net income/loss as a percentage of the revenues.

Cost of revenues were RMB 1,589.7 million, an increase of 24.3%, mainly driven by higher e-scooter sales volume.  The cost per e-scooter, defined as cost of revenues divided by the number of e-scooters sold in a specified period, was RMB 3,773, slightly higher than RMB 3,767 in 2018.

Gross margin was 23.4%, increased substantially from 13.4% in 2018, mainly driven by lower raw material cost, higher sales price, and change in product mix.

Operating expenses were RMB 329.7 million, a decrease of 35.9% from RMB 514.4 million in 2018.  Operating expenses as a percentage of net revenues was 15.9%, compared with 34.8% in 2018.

Operating expenses excluding share-based compensation were RMB 310.3 million, an increase of 24.7%, and represented 14.9% of net revenues, compared with 16.8% in 2018.

Government grants were RMB 29.8 million, increased by 28.4 million compared with the year of 2018, mainly consisting of various incentives from local government authorities.

Share-based compensation was RMB 19.6 million, a decrease of RMB 246.3 million from RMB 265.9 million in 2018.  The decrease was mainly because of the higher expenses that arose from the accelerated vesting of certain restricted ordinary shares during 2018 and the transfer of a number of ordinary shares from a shareholder to one of our vice presidents for nil consideration in June 2018.

Net income was RMB 190.1 million, an increase of RMB 539.1 million from a net loss of RMB 349.0 million in 2018.  The increase was mainly caused by the increased revenues, higher gross margin and lower share-based compensation expenses as described above.

Adjusted net income (non-GAAP) was RMB 209.7 million, compared with an adjusted net loss of RMB 48.7 million in 2018.  The adjusted net income margin was 10.1% in 2019, compared with an adjusted net loss margin of 3.3% in 2018.

Basic and diluted net income per ADS were RMB 2.55 (US$ 0.37) and RMB 2.48 (US$ 0.36) respectively.

Balance Sheet

As of December 31, 2019, the Company had cash, term deposits and short-term investments of RMB 764.8 million in aggregate.  The Company had restricted cash of RMB 221.7 million and short-term bank borrowings of RMB 217.4 million.

Business Outlook

NIU expects revenues of the first quarter 2020 to be in the range of RMB 195 million to RMB 265 million, representing a year-over-year decrease of 45% to 25%, which was due to the adverse impacts of the COVID-19 outbreak on Company’s sales and operation.

The above outlook is based on information available as of the date of this press release and reflects the Company’s current and preliminary expectation, which is subject to change in light of uncertainties and situations related to how COVID-19 develops.

Use of Non-GAAP Financial Measures

To supplement NIU’s consolidated financial results presented in accordance with the accounting principles generally accepted in the United States of America (“GAAP”), NIU uses the following non-GAAP financial measures: adjusted net income/loss, and adjusted net income/loss margin.  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 GAAP.

NIU believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance and liquidity by excluding certain items that may not be indicative of its operating results.  The Company believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing its performance and when planning and forecasting future periods.  These non-GAAP financial measures also facilitate management’s internal comparisons to NIU’s historical performance.  The Company believes these non-GAAP financial measures are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision making.  A limitation of using these non-GAAP financial measures is that these non-GAAP measures exclude certain items that have been and will continue to be for the foreseeable future a significant component in the Company’s results of operations.  These non-GAAP financial measures presented here may not be comparable to similarly titled measures presented by other companies.  Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to the Company’s data.

Adjusted net income/loss is defined as net income/loss excluding share-based compensation expenses and change in fair value of a convertible loan.  Adjusted net income/loss margin is defined as adjusted net income/loss as a percentage of the revenues.
