国泰海通｜建材：需求有结构性亮点，盈利改善或快于营收

Core Viewpoint - The construction materials industry is showing various structural highlights in the 2025 mid-year report, with multinational expansion and high-end demand significantly contributing to profitability. Different sub-industries in the domestic market are reaching a consensus on improving profitability, with the pace of profitability recovery potentially outpacing revenue recovery [1]. Group 1: Cement Sector - The cement sector has demonstrated pricing elasticity, with overseas profitability advantages being strong. In Q2 2025, the profitability of the cement industry showed a pattern of high-to-low within the quarter, with April and May continuing the price advantages and raw material cost reductions from Q1, contributing to a year-on-year increase in profitability [2]. - Starting in June, supply-demand pressures increased, leading to a retraction in profitability, but it is confirmed that 2024 is likely the bottom for profit per ton, with further downward pressure being difficult [2]. - The focus on limiting overproduction remains crucial for improving supply-demand dynamics, and there is an expectation for improved shareholder returns driven by industry equity incentives [2]. Group 2: Consumer Building Materials - The profitability recovery in the consumer building materials sector is showing higher elasticity compared to revenue elasticity. In Q2, the revenue growth rate for this sector remained similar to Q1, with expectations that the revenue growth bottomed out in Q3 2024 [3]. - The industry has generally seen some recovery, with price disadvantages year-on-year being a core factor affecting revenue appearance. However, entering Q3, a significant recovery is anticipated due to base effects [3]. - Price recovery and structural upgrades in the coatings and waterproofing sectors are leading the way, while personnel and cost optimizations have significantly improved profitability in the first half of 2025 [3]. Group 3: Glass and Fiberglass - In the fiberglass sector, high-end demand from wind power and thermoplastics is supporting continuous improvement in net profit per ton for leading companies. The demand trend for AI in electronic fabrics is expected to drive both volume and price increases [4]. - The structural upgrade and demand expansion in the specialty electronic fabric sector remain a certain trend, with leading companies deepening their participation [4]. - In the glass sector, the float glass market is experiencing price stabilization amid supply-demand stalemate, while photovoltaic glass has seen slight price rebounds following self-regulated production cuts during extreme losses [4].
