In 2025, the company completed a RMB 100 million (~US$13.7 million) Series D financing at a post-money valuation of RMB 4.05 billion (~US$556 million) .
NASN remains pre-profit, though its financial trajectory shows improving unit economics:
| Metric | 2023 | 2024 | 2025 |
|---|---|---|---|
| Revenue | RMB 272M | RMB 391M | RMB 615M |
| Gross Profit | RMB 3.1M | RMB 41.9M | RMB 83.6M |
| Gross Margin | 1.1% | 10.7% | 13.6% |
| Net Loss | -RMB 201M | -RMB 170M | -RMB 190M |
| Loss Rate (net loss/revenue) | 73.8% | 43.4% | 30.8% |
Revenue more than doubled from RMB 272 million in 2023 to RMB 615 million in 2025, driven by growing adoption of its brake-by-wire solutions in China's new energy vehicle market. Gross margin improved from 1.1% to 13.6% over the same period, reflecting better scale and product mix. Net losses, while still substantial at RMB 190 million in 2025, narrowed as a percentage of revenue from 73.8% to 30.8%, indicating a path toward breakeven if revenue growth continues .
NASN operates in the fast-growing brake-by-wire segment, a critical technology enabler for L3 and higher autonomous driving. Brake-by-wire systems replace traditional mechanical linkages with electronic signal transmission, offering faster response times, higher precision, and better compatibility with autonomous driving stacks .
The company is one of the top three domestic Chinese suppliers of brake-by-wire solutions, competing primarily with foreign suppliers in a market that is still in early adoption . Its major backer CATL, the world's largest battery manufacturer, provides strategic industry connections, while Hillhouse and Qiming add financial credibility for IPO investors
