Shares of CNBM (03323) are rising strongly against the broader market trend. At the time of writing, the stock is up nearly 14% to HK$6.04, with a trading volume exceeding HK$1.3 billion.
Key Drivers Behind the Rally
The price surge is linked to significant developments in the upstream materials sector. Leading copper-clad laminate manufacturer Kingboard Laminates implemented its fifth price increase this year on June 16th, raising prices for all thicknesses of FR-4 CCL and prepreg by 15%. A core component of CCL, electronic fabric, has seen prices for common specifications soar more than 70% since the beginning of the year. This material constitutes 25% to 40% of CCL production costs, and a shortage of fiberglass raw materials is directly pressuring substrate manufacturers to raise prices.
Supply Constraints in the Market
Furthermore, delivery cycles for high-end, low-dielectric electronic fabric have lengthened. The lead time for new loom equipment now exceeds one year, indicating no short-term new supply to alleviate the current market gap.
Company's Strategic Positioning
Public information indicates that CNBM holds controlling stakes in two major industry players: China Jushi and Sinoma Science & Technology. These subsidiaries cover the two main electronic fabric market segments—general-purpose and high-end—positioning the group to benefit comprehensively from the current industry-wide supply crunch.
It is reported that China Jushi is a global leader in the fiberglass industry and operates the largest domestic electronic fabric capacity, primarily focusing on standard-grade fabric. Sinoma Science & Technology's wholly-owned subsidiary, Taishan Fiberglass, is a domestic leader with a full product portfolio in specialty electronic fabrics.
