First Quarter 2025 Financial Results

Revenues reached RMB 682.0 million, representing a 35.1% increase year-over-year. This growth was mainly driven by a 57.4% increase in sales volume, partially offset by a 14.2% decrease in revenues per e-scooter. The following table shows the revenue breakdown and revenues per e-scooter in the periods presented:

Cost of revenues was RMB 563.9 million, an increase of 37.8% year-over-year, in line with the growth trend 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 2,774, a decrease of 12.5% from RMB 3,169 in the first quarter of 2024. This decrease was mainly due to changes in product mix, along with the cost-reduction impact in 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 17.3%, compared with 18.9% in the same period of 2024. The decrease was mainly attributable to the international market, including changes in the product mix of kick-scooters, higher freight costs and tariffs, and inventory write-downs. This was partially offset by increased gross margin in China market, reflecting the positive impact of cost-reduction initiatives.

Operating expenses were RMB 165.1 million, a slight increase of 0.1% year over year. Operating expenses as a percentage of revenues was 24.2%, compared with 32.7% in the first quarter of 2024.
