China National Building Material Co Ltd shares tumbled 10.5% to HK$3.85 on Wednesday after the company issued a profit warning for the first half of 2026. The firm said it now expects an unaudited shareholders' loss of approximately RMB 890 million for the six months ended June 30, 2026, compared with a profit of roughly RMB 1.36 billion in the same period of 2025.
The company attributed the reversal to a combination of weaker selling prices and softer volumes. Management singled out lower selling prices for cement, ready-mix concrete and aggregates, together with reduced sales volumes for ready-mix concrete and gypsum products - factors that point to ongoing pricing pressure across China's building materials sector.
Investors had seen earlier signs of strain at the group. China National Building Material reported a full-year net loss for 2025 and recorded a still-negative but smaller loss in the first quarter of 2026. Several of its subsidiaries - including Tianshan Material, Beijing New Building Materials and Sinoma International - recorded year-on-year declines in both revenue and profit in the most recent quarter, adding to concerns about the durability of earnings across the group's operating units.
The share price hit an intraday 52-week low of HK$3.77 before a slight recovery to HK$3.85 by the close. The profit warning and the string of weak subsidiary results reinforced investor apprehension that core markets for cement and concrete remain under structural pressure, with no immediate improvement in prices apparent from the company's disclosures.
Those company-specific headwinds come against a challenging wider backdrop. The announcement arrived as China's property market continues to struggle to regain momentum following a series of high-profile developer bankruptcies and credit stresses. Gross domestic product data released on Wednesday also showed that the country's economy expanded less than expected in the second quarter, a macro backdrop that may be weighing on demand for building materials.
Summary
China National Building Material warned of an estimated H1 2026 shareholders' loss of about RMB 890 million versus H1 2025 profit of about RMB 1.36 billion. The company pointed to lower selling prices for cement, ready-mix concrete and aggregates and weaker volumes for ready-mix concrete and gypsum products as the primary drivers. The stock fell to a 52-week low intraday and several subsidiaries reported year-on-year revenue and profit declines in the latest quarter.
Key points
- Company expects an unaudited H1 2026 loss of approximately RMB 890 million, compared with a H1 2025 profit of about RMB 1.36 billion.
- Primary causes cited are lower selling prices for cement, ready-mix concrete and aggregates, plus weaker volumes for ready-mix concrete and gypsum products; multiple subsidiaries posted year-on-year declines.
- Broader pressures include a struggling property market and Q2 GDP growth that came in below expectations, which may be dampening demand for building materials and construction-related sectors.
Risks and uncertainties
- Continued pricing pressure in cement and concrete markets could further erode margins and cash flow for the company and its subsidiaries - impacting the building materials and construction sectors.
- Persisting weakness in China's property sector, highlighted by recent bankruptcies and credit constraints, may limit near-term recovery in demand for construction materials.
- Ongoing negative results at subsidiaries create uncertainty about the pace of financial stabilization at the group level and may weigh on investor confidence in industrial and materials-focused equities.
