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].
