Investment Rating - The industry investment rating is "Positive" and maintained [12] Core Viewpoints - The demand for special electronic fabrics is a blue ocean, with domestic leaders actively expanding [6] - Cement prices continue to rise, while glass inventory has shifted from increasing to decreasing [7] - The report recommends focusing on special fabrics and the African chain, with existing leaders as the main line for the year [9] Summary by Relevant Sections Special Electronic Fabrics - China National Materials Technology has announced new expansion plans, indicating strong commitment. Taishan Fiberglass plans to invest 1.81 billion yuan to build a project with an annual output of 35 million meters of special fiber fabric and another 1.75 billion yuan for a project with an annual output of 24 million meters of ultra-low loss low dielectric fabric (Q fabric). The total annual output of these projects will reach 59 million meters, with a construction period of 18 months. The funding will come from self-owned funds and bank loans. After production, the total capacity is expected to reach approximately 120 million meters. Additionally, China Jushi has also confirmed its increased investment in the special electronic fabric sector. AI electronic fabrics are expected to be a new wave for industry leaders, considering the high technical barriers, product iteration, and sustained unexpected demand [6]. Cement Market - As of the end of August, cement demand has slightly rebounded in southern regions due to reduced rainfall. However, demand has weakened in regions like Beijing-Tianjin-Hebei, Shandong, and Henan due to stricter environmental controls. The average cement shipment rate in key regions is approximately 45.3%, a decrease of 0.2 percentage points month-on-month. Some areas are still actively pushing for price increases, leading to an overall market price increase of 0.5% [7]. Glass Market - The domestic float glass market has seen a slight improvement in transactions, with prices gradually stabilizing and some areas experiencing minor price increases. As downstream processing plants further digest inventory, there has been a slight increase in essential replenishment, supporting float glass manufacturers. However, the current inventory level remains high, and speculative sources still pose risks. The production capacity has slightly increased, with 283 float glass production lines in total, 222 of which are operational, with a daily melting capacity of 158,855 tons [8][36]. Recommendations - The report recommends focusing on core leader China National Materials Technology due to the explosive demand for AI and high supply barriers in special electronic fabrics. The report also highlights the African chain, recommending Keda Manufacturing, which has advantages in production, channels, and brand in the African market. The report anticipates continued recovery in net profit margins in 2025H, benefiting from the recovery in lithium carbonate prices. Additionally, it recommends Huaxin Cement and Western Cement, noting Huaxin's acquisition of Haorui's Nigerian assets, which enhances overseas profit elasticity [9].
