Tianfeng Securities·2025-09-01 10:15Investment Rating - Industry Rating: Outperform the market (maintained rating) [5] Core Viewpoints - The cement and fiberglass sectors showed significant improvement in Q2 year-on-year, with cement prices experiencing a sequential decline but profitability still increasing year-on-year. Fiberglass benefited from rising prices of thermoplastics and wind power yarn, leading to a continued increase in gross margins. The product structure advantages of leading companies are becoming more evident, with specialty fiber cloth contributing to profit growth [2][11] - The demand for consumer building materials is negatively impacted by the decline in new construction and completion in the real estate sector, resulting in a year-on-year revenue decrease. However, the revenue decline for waterproofing and board materials in Q2 narrowed compared to Q1. The glass demand remains weak, with prices and gross margins continuing to decline in Q2, leading to an average gross loss across the industry. As loss pressures increase, the pace of industry cold repairs may accelerate, with potential for price improvements in the short term [2][11] - The report continues to recommend traditional building materials with improving fundamentals, such as cement and coatings, as well as high-end electronic fabrics and overseas markets with high demand growth [2][20] Summary by Sections Market Review - During the week of August 25-29, 2025, the Shanghai and Shenzhen 300 index rose by 2.71%, while the building materials sector (CITIC) increased by 0.53%, with the fiberglass sector performing particularly well.
