Core Viewpoint - The report from Guotai Junan indicates that the price increase of traditional fiberglass electronic cloth has accelerated since February, confirming the view that the shift of weaving machine capacity to AI electronic cloth has led to a supply shortage of traditional cloth [1][2]. Group 1: Price Increase and Supply Shortage - The price of traditional electronic cloth has risen significantly in February, with the first week of February seeing prices for 7628 electronic cloth ranging from 4.9 to 5.45 yuan per meter, an increase of 0.5 to 0.6 yuan per meter compared to the previous month [2]. - The announcement from Taiyao Technology on February 10 regarding reduced supply of E-glass products due to strong demand for low-dielectric materials has further fueled expectations of a shortage in traditional cloth [2]. Group 2: Inventory Levels and Profitability - Current inventory levels for leading traditional electronic cloth manufacturers are only two weeks, compared to a normal level of 1 to 1.5 months, primarily due to the impact of weaving machines shifting to produce AI specialty cloth [3]. - The expected increase in prices is likely to boost profitability for leading companies, with China Jushi's traditional electronic cloth capacity at 1 billion meters and Jiantao's at 800 million meters [3]. Group 3: AI Electronic Cloth Demand - The shortage of traditional cloth and the strong demand for AI electronic cloth are interconnected, with 2026 expected to be a year of realization for AI specialty cloth demand [4]. - The demand for CTE cloth has been driven by the packaging board needs of AI chips and consumer electronics, while low-dielectric cloth is expected to see stable demand from specific applications [4]. Group 4: Recommended Stocks - The report recommends investment in China Jushi (600176.SH), Jiantao Laminated Board (01888), and China National Materials (002080.SZ), along with related companies such as International Composites (301526.SZ) and Honghe Technology (603256.SH) [5].

Core Viewpoint - The article maintains a "buy" rating, highlighting accelerated price increases for traditional fiberglass electronic fabrics since February, confirming previous reports that machine capacity shifts to AI electronic fabrics have led to supply shortages in traditional fabrics, thereby enhancing profitability for leading fiberglass companies [1]. Group 1: Price Increases and Supply Shortages - Traditional electronic fabric prices have surged in February, with the first week of February seeing prices for 7628 electronic fabric ranging from 4.9 to 5.45 yuan per meter, an increase of 0.5 to 0.6 yuan per meter compared to the previous month [1]. - The announcement by Taiyao Technology on February 10 indicated a reduction in E-glass supply due to high demand for low-dielectric fabrics, further exacerbating the supply shortage of traditional fabrics [1][2]. Group 2: Inventory Levels and Production Capacity - Current inventory levels for leading traditional electronic fabric companies are only two weeks, significantly lower than the normal inventory level of 1 to 1.5 months, primarily due to the shift in weaving machine production to AI specialty fabrics [2]. - Planned expansions for traditional electronic fabric production include 85,000 tons from International Composite Materials and 100,000 tons from China Jushi in Huai'an, with the latter expected to contribute 1 to 1.5 billion meters of electronic fabric capacity [2]. Group 3: AI Electronic Fabric Demand - The shortage of traditional fabrics and the strong demand for AI electronic fabrics are interconnected, with 2026 expected to be a year of realization for AI electronic fabric demand [3]. - The demand for CTE fabrics has been driven by the packaging board needs of AI chips and consumer electronics, with limited suppliers contributing to a high degree of scarcity [3]. - The overall increase in demand for low-dielectric fabrics is expected to remain strong, with significant growth anticipated in 2026 as AI electronic fabrics enter a phase of realization [3].

Investment Rating - The report maintains an "Overweight" rating for the fiberglass electronic cloth industry, indicating a projected increase of over 15% relative to the CSI 300 index within the next 12 months [4][10]. Core Insights - The acceleration in price increases for traditional fiberglass electronic cloth since February, combined with reduced supply of E-glass products announced by Taiyao Technology, has led to a continued expectation of tight supply for traditional cloth, enhancing profitability for leading fiberglass companies [2][4]. - The report highlights that the tight supply of traditional electronic cloth is primarily driven by two factors: unexpected price increases in February and a significant reduction in E-glass supply due to production shifts towards low-dielectric cloth [4]. - The report anticipates that 2026 will be a year of realization for AI electronic cloth, with strong demand expected to translate into financial performance for companies with comprehensive product structures and leading customer certifications [4].
