Investment Rating - The investment rating for the company is "Buy" (maintained) [6] Core Views - The company is a leading player in the domestic lithium battery precision structural components sector, achieving steady revenue and profit growth due to its strong technical foundation and scale advantages, solidifying its position as a cyclical leader. The company is proactively expanding into the robotics sector, focusing on harmonic reducers, modules, and dexterous hands to create a second growth curve [4][12][18]. Summary by Sections 1. Leading Position in Lithium Battery Structural Components - The company's structural components business continues to grow steadily, with a CAGR of 57.2% in precision structural component revenue from 2020 to 2024. The company benefits from economies of scale, with stable gross and net profit margins. With the ramp-up of production capacity in Europe and the establishment of factories in Malaysia and the USA, the company enhances its local supply capabilities, reducing logistics costs and strengthening supply chain relationships, which may lead to an increase in global market share [13][27][32]. 2. Robotics Sector Expansion - The company has initiated its robotics sector layout by establishing joint ventures focused on key components like harmonic reducers. The new harmonic reducers utilize lightweight PEEK materials, offering advantages such as high strength, high-temperature resistance (260℃), and wear resistance, significantly improving transmission accuracy and lifespan. This technology can also be applied in aerospace, medical devices, and semiconductor manufacturing, driving product upgrades towards higher value-added segments [14][21][62]. 3. Financial Forecast and Investment Recommendations - The company is expected to achieve revenues of 144.81 billion, 174.62 billion, and 211.69 billion yuan from 2025 to 2027, with year-on-year growth rates of 20%, 21%, and 21% respectively. The net profit attributable to shareholders is projected to be 18.01 billion, 21.50 billion, and 26.51 billion yuan, with growth rates of 22%, 19%, and 23%. The EPS is expected to be 6.58, 7.86, and 9.69 yuan per share, with a 3-year CAGR of 21.68%. The corresponding PE ratios are projected to be 17, 14, and 12 times [20][30][31].
