Third Quarter 2025 Financial Results

Revenues reached RMB 1,693.9 million, representing a 65.4% increase year-over-year. This growth was mainly driven by a 49.1% increase in sales volume, complemented by an 11.0% increase in revenues per e-scooter. The following table shows the revenue breakdown and revenues per e-scooter in the periods presented:

Revenues (in RMB million)	2025 Q3		2024 Q3		% change YoY

Accessories, spare parts and services		145.0		96.2		+50.8	%
Total		1,693.9		1,023.9		+65.4	%

Accessories, spare parts and services³		311		307		+1.3	%

E-scooter sales revenues from China market were RMB 1,481.9 million, an increase of 85.8% year-over-year, and represented 95.7% of total e-scooter revenues. The increase was mainly due to a 74.2% increase in sales volume and a 6.7% increase in revenues per e-scooter in China market.

E-scooter sales revenues from international markets were RMB 67.0 million, a decrease of 48.6% year-over-year, and represented 4.3% of total e-scooter revenues. The decrease was mainly due to reduced sales volume and lower revenues per e-scooter of kick-scooters in international markets.

Accessories, spare parts sales and services revenues were RMB 145.0 million, an increase of 50.8% year-over-year, and represented 8.6% of total revenues. The increase was mainly due to an increase in accessories and spare parts sales in China market.

Revenues per e-scooter were RMB 3,636, an increase of 11.0% year-over-year, mainly due to increased sales proportion and higher revenues per e-scooter in China market.

Cost of revenues was RMB 1,324.1 million, an increase of 50.1% year-over-year, lower than the growth rate of revenues. The cost per e-scooter, defined as cost of revenues divided by the number of e-scooters sold in a specific period, was RMB 2,842, a slight increase from RMB 2,824 in the third quarter of 2024. The increase resulted from increased costs in international markets, which was partially offset by cost reductions in the China market.

² Revenues per e-scooter on e-scooter sales from China or international markets is defined as e-scooter sales revenues from China or international markets divided by the number of e-scooters sold in China or international market in a specific period

³ Revenues per e-scooter on accessories, spare parts and services is defined as accessories, spare parts and services revenues divided by the total number of e-scooters sold in a specific period

Gross margin was 21.8%, compared with 13.8% in the same period of 2024. The increase was mainly driven by a higher proportion of e-scooter sales and an improved gross margin in China market, benefiting from our cost-reduction initiatives.

Operating expenses were RMB 297.1 million, an increase of 48.1% from the same period of 2024. Operating expenses as a percentage of revenues was 17.5%, compared with 19.6% in the third quarter of 2024.

Selling and marketing expenses were RMB 214.9 million (including RMB 1.2 million of share-based compensation), an increase of 68.3% from RMB 127.7 million in the third quarter of 2024, primarily driven by a RMB 74.7 million increase in spending on marketing and promotion in China market. Selling and marketing expenses as a percentage of revenues was 12.7%, compared with 12.5% in the third quarter of 2024.

Research and development expenses were RMB 43.4 million (including RMB 2.2 million of share-based compensation), an increase of 43.2% from RMB 30.3 million in the third quarter of 2024, mainly due to a RMB 6.2 million increase in design and testing expenses, and a RMB 5.9 million increase in staff cost and share-based compensation. Research and development expenses as a percentage of revenues was 2.6%, compared with 3.0% in the third quarter of 2024.

General and administrative expenses were RMB 38.8 million (including RMB 3.1 million of share-based compensation), a decrease of 8.9% from RMB 42.6 million in the third quarter of 2024, mainly due to reversal of bad-debt provision, partially offset by an increase in taxes and surcharges. General and administrative expenses as a percentage of revenues was 2.3%, compared with 4.2% in the third quarter of 2024.

Operating expenses excluding share-based compensation were RMB 290.6 million, an increase of 49.8% year over year, and represented 17.2% of revenues, compared with 18.9% in the third quarter of 2024.

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. Adjusted net income (loss) margin is defined as adjusted net income (loss) as a percentage of the revenues.
