Investment Rating - The industry investment rating is "Positive" (maintained) [6] Core Viewpoints - The overseas AIDC construction remains robust, while domestic demand is expected to rebound in 2026. In the second half of 2025, there is a clear divergence in AIDC construction between domestic and international markets. North America continues to experience high levels of capital expenditure, with the four major cloud providers' capital spending reaching $257.4 billion in the first three quarters of 2025, a 65% year-on-year increase. In contrast, domestic cloud providers are experiencing a temporary slowdown in capital expenditure growth due to restrictions on high-end computing card imports, which has delayed some AIDC project timelines. However, this impact is seen as a deferral of demand rather than a disappearance of demand. As overseas supply of computing cards improves and domestic alternatives continue to develop, a "pent-up rebound" in domestic AIDC construction is anticipated in 2026, indicating potential for demand release [1]. Summary by Sections AIDC Equipment - The report highlights the ongoing high demand for AIDC equipment in North America, driven by rapid growth in AI computing needs and delayed power grid construction, leading to increased orders for gas turbines for self-generation or distributed power supply [2]. Gas Turbines - The global gas turbine market is characterized by a significant supply-demand imbalance, with an expected increase of over 85 GW in global gas turbine orders in 2025, while existing effective capacity is around 50 GW. The market is dominated by GE, Siemens Energy, and Mitsubishi Heavy Industries, which together hold an 88% market share. The backlog of orders extends to 2028, creating opportunities for Chinese companies to enter the overseas market [2][3]. Diesel Generators - Diesel generators are essential backup power sources in AIDC construction, with a long-term market dominated by Cummins, MTU, and Caterpillar, which together hold about 85% of the market share in China. Current capacity bottlenecks faced by overseas manufacturers present a window of opportunity for domestic manufacturers like Weichai to replace foreign brands and expand internationally [4]. Cooling Equipment - The report notes that the rapid increase in AI chip power consumption is pushing the adoption of liquid cooling solutions, as traditional air cooling approaches reach their physical limits. This trend is expected to drive demand for related cooling equipment [5]. Emerging Technologies - Solid Oxide Fuel Cells (SOFC) are being explored as a solution to power shortages in North America, offering high modularity, short delivery cycles, and high efficiency. The report suggests that SOFC costs are approaching those of gas turbines, indicating a potential growth area [7]. Data Center Busbars - The traditional "rack and cable" approach in high-power density scenarios is being replaced by intelligent busbar solutions, which offer higher reliability and easier maintenance, marking a significant upgrade direction for data center power distribution systems [8]. Investment Recommendations - The report recommends focusing on several key areas: gas turbines, diesel generators, cooling equipment, and emerging technologies like SOFC and data center busbars, as these sectors are expected to benefit from structural opportunities driven by both domestic and international demand [8]. Key companies to watch include Yingliu, Ice Wheel Environment, Weichai Power, Haomai Technology, and Jerry [8].
