China National Building Material (HKG:3323) expects its first-quarter 2025 loss to narrow significantly to approximately 520 million yuan, compared to a 1.35 billion yuan loss in the same period last year, according to its Wednesday bourse filing.

The improvement stems from higher selling prices and lower production costs for its core cement and glass fiber products, coupled with increased sales of wind turbine blades and coatings.

While preliminary estimates suggest a positive trend, the company cautions investors that final unaudited results for the quarter ending March 31 may differ when officially released by end-April 2025.
