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. Effective Date Effective from February 1, 2026 SMM Information & Technology Co., Ltd. SMM Copper Research Team Liang Kaihui, 86-21-5159-5826 January 21, 2026

Respected Client, To keep pace with the rapid development of the magnesium industry and the evolving needs for supply-demand analysis, our company has optimized the data model based on the SMM Magnesium Database and is now systematically upgrading the data standards and historical data for magnesium-related metrics in China and globally. Details are as follows: Data Standards and Historical Data Adjustment Notice I. Background of Adjustment With the rapid growth of downstream magnesium alloy demand, the magnesium market landscape continues to evolve. Factors such as technological advancements in die-casting equipment, varying penetration rates of magnesium alloy die-cast parts across different thickness markets, and recycling utilization rates have significantly impacted recycled magnesium production. To better capture the effects of industry changes on supply-demand analysis, and in conjunction with SMM's further in-depth research on the proportion of magnesium added in aluminum industry processes—improving recycled magnesium recovery and utilization coefficients and revising historical data for "primary magnesium" and "magnesium powder" production—we are now adjusting and updating the following metrics in the balance sheet: "recycled magnesium supply," "primary magnesium supply," "magnesium consumption in aluminum products," and "magnesium powder production." II. Adjustment Details Data Points Revised: "Recycled Magnesium Supply," "Primary Magnesium Supply," "Magnesium Consumption in Aluminum Products," "Magnesium Powder Production." Revision Scope: Historical data from January 1, 2023, onward (including retrospective revisions and future forecasts). III. Effective Date December 12, 2025 Shanghai Metals Market Information & Technology Co., Ltd. SMM Magnesium Research Team Zhu Qifan 86-21-5166-6729 December 12, 2025
