Summary of Key Points from Conference Call Records Industry Overview Deep Sea Technology - Deep sea technology has been included in the government work report for the first time, alongside low-altitude economy and commercial aerospace, primarily targeting the B2B market. Key areas include resource extraction, energy development, and related equipment and materials. By 2025, the marine production value is expected to exceed 13 trillion yuan, with deep sea technology-related industries accounting for over 25%, resulting in a market size exceeding 3.25 trillion yuan [1][8]. Domestic Large Aircraft Market - The domestic large aircraft market is expected to develop significantly beyond expectations, with COMAC (China Commercial Aircraft Corporation) playing a crucial role. The production capacity plan for 2025 has been increased from 50 to 75 aircraft, with procurement expected to rise by 70% from 200 billion yuan in 2024. Key sectors include complete aircraft manufacturing, engines, onboard systems, components, and materials [1][5][11]. Engineering Machinery Industry - The engineering machinery industry is projected to continue growing by over 10% in 2025, building on a strong performance in 2024. New opportunities from the deep sea economy and technology may drive growth in shipbuilding and military industries. SANY Heavy Industry has recently repurchased 1 to 2 billion yuan for employee stock ownership, with Q1 performance expected to grow by 20% to 30% [1][6][10]. Humanoid Robotics Industry - The humanoid robotics industry is gradually entering everyday life, with a business model primarily targeting the consumer market (B2C). The industry chain is expanding beyond Tesla to include major domestic equipment manufacturers and core components such as harmonic reducers, sensors, and dexterous hands [1][7][10]. Core Insights and Arguments Performance of Indices - In 2025, the humanoid robotics index has risen by 34%, outperforming the Hang Seng Technology Index by 26% and exceeding the artificial intelligence index by nearly 20%. Growth sectors include engineering machinery and lithium battery equipment, with engineering machinery continuing to grow by over 10% [2]. Low Altitude Economy - The low-altitude economy is expected to scale up in 2025, with new technologies and products set to be widely applied under policy support. A guiding document is anticipated in Q2 to accelerate investment and operational progress in six pilot cities [3][12]. New Energy Vehicles - The penetration rate of new energy vehicles has rapidly increased, benefiting both manufacturers and component suppliers. BYD is recommended as a leading manufacturer, while component companies focusing on lidar, vision technology, and chips are also highlighted. King Long Motors has shown strong export performance, with increasing average prices and profit margins [3][14][15]. Key Companies in Deep Sea Technology - Important companies in the deep sea technology sector include Yaxing Anchor Chain, China Offshore Oil Engineering, and Oriental Cable, which hold significant positions in shipbuilding, oil and gas extraction, and wind power [4][8][9]. Engineering Machinery and Humanoid Robotics Companies - In the engineering machinery sector, SANY Heavy Industry's recent stock buyback indicates confidence in future growth, with Q1 performance expected to increase significantly. In humanoid robotics, the industry chain is expanding, with key players including Wuzhou New Spring and Jinwo Co., focusing on North American clients [10]. Additional Important Insights Giant Star Technology - Giant Star Technology has a leading overseas production layout, with over 60% of its revenue coming from the North American market. The company is less affected by tariffs, with only about 10% risk exposure from potential tariffs on exports to the U.S. The aging housing market in the U.S. supports stable demand for tools, indicating long-term growth potential [18][19]. Market Expectations for Companies with Overseas Production - Companies with overseas production capabilities are expected to have better market pricing due to their enhanced competitiveness in U.S. exports and reduced tariff impacts. This positions them favorably for potential earnings recovery [20].
