2 The discrepancy in the total number of e-scooters sold in the fourth quarter of 2025 disclosed herein and the sales volume disclosed in the Company’s press release on sales volume update dated January 5, 2026 was due to adjustments made for certain product returns in international markets that occurred subsequently in the first quarter of 2026. This adjustment was made in order to better align with the revenue recognized for product sales during the fourth quarter of 2025.

Dr. Li continued, “Internationally, we are optimizing our retail footprint by accelerating the roll-out of electric motorcycles while streamlining micromobility operations to maximize efficiency. Overall, we are confident to deliver a sustained performance across both our domestic and overseas markets in 2026.”

Fourth Quarter 2025 Financial Results

Revenues reached RMB 676.2 million, representing a 17.4% decrease year over year. This decrease was primarily driven by a 23.8% decrease in sales volume, partially offset by a 4.0% increase in revenues per e-scooter. The following table shows the revenue breakdown and revenues per e-scooter in the periods presented:

3 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

4 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

Cost of revenues was RMB 573.0 million, a decrease of 20.1% year over year, mainly due to lower sales volume. The cost per e-scooter, defined as cost of revenues divided by the number of e-scooters sold in a specific period, was RMB 3,317, an increase of 4.8% from RMB 3,165 in the fourth quarter of 2024. This increase was mainly due to provisions for slow-moving inventory and higher freight costs in international markets, partially offset by cost-reduction initiatives in China market.

Gross margin was 15.3%, compared with 12.4% in the same period of 2024. The increase was primarily attributable to China market, driven by a favorable product mix shift towards higher-margin e-scooters and effective cost-reduction initiatives. This was partially offset by lower gross margin for kick-scooters in international markets.

Operating expenses were RMB 206.1 million, an increase of 6.8% from the same period of 2024. Operating expenses as a percentage of revenues were 30.5%, compared with 23.6% in the fourth quarter of 2024.

Operating expenses excluding share-based compensation expenses were RMB 200.6 million, an increase of 7.1% year over year, representing 29.7% of revenues, compared with 22.9% in the fourth quarter of 2024.

Share-based compensation expenses were RMB 5.7 million, compared with RMB 5.9 million in the same period of 2024.

Income tax benefit was RMB 8.0 million, compared with RMB 9.8 million in the same period of 2024.

Net loss was RMB 88.1 million, compared with RMB 72.5 million in the fourth quarter of 2024. The net loss margin was 13.0%, compared with 8.9% in the same period of 2024.

Adjusted net loss (non-GAAP) was RMB 82.4 million, compared with RMB 66.7 million in the fourth quarter of 2024. The adjusted net loss margin5 was 12.2%, compared with 8.1% in the same period of 2024.

Basic and diluted net loss per ADS were both RMB 1.10 (US$ 0.16).

Full Year 2025 Financial Results

Revenues were RMB 4,307.9 million, representing a 31.0% increase year over year. This growth was primarily driven by a 29.0% increase in sales volume, complemented by a 2.1% increase in revenues per e-scooter. E-scooter sales revenues from China market and international markets represented 93.2% and 6.8% of our total revenues from e-scooter sales, respectively. The following table shows the revenue breakdown and revenues per e-scooter in the years presented:

5 Adjusted net income (loss) margin is defined as adjusted net income (loss) (non-GAAP) as a percentage of the revenues

Cost of revenues was RMB 3,464.3 million, an increase of 24.2% 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 specific period, was RMB 2,906, a decrease of 3.7% from RMB 3,018 in 2024.

Gross margin was 19.6%, compared with 15.2% in 2024. The increase was primarily driven by China market, reflecting a strategic shift in product mix towards higher-margin e-scooters and our continued cost-optimization initiatives. This was partially offset by a lower gross margin for kick-scooters in international markets.

Operating expenses were RMB 933.2 million, an increase of 24.4% from RMB 750.3 million in 2024. Operating expenses as a percentage of revenues were 21.7%, compared with 22.8% in 2024.

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.
