China National Building Material Company Limited provided earning guidance for six months ended 30 June 2023. Company informed the shareholders and potential investors of the Company that, based on its preliminary review of the relevant financial statements of the Company and its subsidiaries (the "Group"), it is expected that the unaudited profit attributable to equity holders of the Group for the six months ended 30 June 2023 will decrease by approximately 80% when compared with the corresponding period in 2022. The above expected decrease is mainly attributable to the decrease in sales prices of cement, commercial concrete and glass fiber (being the major products of the Group), the decrease in sales volumes of cement and commercial concrete, the decline in performance attributed by the associates and the reduction in gains on disposal of assets, although part of which has been offset by the decrease in cost of sales of cement and commercial concrete and the decrease in loss of fair value of the financial assets recognized at fair value in the profit and loss accounts of the Group.
