Dear Customer, Dear Valued Client, To keep pace with the rapid development of the secondary copper industry and meet the market's need for in-depth analysis of the recycling industry and the supply-demand pattern of copper cathode, our company has conducted a deep optimization of our data models. We are now systematically upgrading and adjusting the standards and content of monthly supply-demand balance data related to China's copper scrap, and implementing the following treatment for historical data: I. Adjustments Made This upgrade primarily optimizes and updates the following indicators in the balance sheet: Discontinuation of "SMM Domestic Copper Scrap Supply" and "SMM Domestic Copper Scrap Supply - Forecasted Value," and adjustment of the two data points under "Domestic Copper Scrap Production": "Domestic Old Scrap Production (Metal Content)" and "Domestic Old Scrap Production (Metal Content) - Forecasted Value." (Data modification path: Database - Copper - Copper Scrap - Production) II. Treatment of Historical Data Historical domestic copper scrap production data will no longer be updated starting from September 2025. Subsequent data will be uniformly released according to the new standards, with the revised data retroactively applied from January 2025. If you have any questions, please feel free to contact the SMM customer service team at any time. Thank you for your continued support and trust! III.
