Such increase in the amount of the Net Profit (as compared to the same for the 1H2023) was primarily due to the following reasons: — the relative low level of profitability of the Group for the 1H2023 for comparison purpose; — increases in the sales volume of the Group’s major solar glass products for the 1H2024 as compared to the same for the 1H2023; and ? 1 ?— improvement in the gross profit margin during the 1H2024 as a result of decreases in the costs of certain raw materials and energy as well as the Group’s continuous enhancement in production capacity and efficiency which was partially offset by the decreasing average selling prices of certain solar glass products of the Group.However the Group’s performance for the 1H2024 is not expected to be as good as that for the six months ended 31 December 2023.The contents of this announcement are based on the information currently available to the Board which includes but without limitation to the operating and financial data of the Group for the five months ended 31 May 2024.
