SMM has reviewed and refined its 2025 energy storage data, adjusting monthly shipment volumes and renaming data points for clarity.

Dear Users, Greetings! Against the backdrop of profound changes in the global chromium resource landscape, to better serve participants in the chromium industry chain and facilitate connectivity in the global chromium market, SMM has launched the "Global Ferrochrome Supply-Demand Balance" and "Global Chromium Ore Supply-Demand Balance" datasets after extensive groundwork and market research. The datasets date back to 2020, with annual updates for the previous year and forecasts for the current year released on March 1st each year. We would like to express our sincere gratitude for your long-standing trust and support for SMM's data services. Should you have any questions or require further information, please do not hesitate to contact us. SMM Nickel Research Team January 9, 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

Dear Client, To keep pace with the rapid development of the magnesium metal industry and the growing need for supply-demand pattern analysis, our company has deeply optimized the data model based on the SMM Magnesium Database and is now systematically upgrading and adjusting the data standards and historical data related to magnesium metal in China. The details are as follows: I. Data Standard Upgrades and Data Revision Notes Background of Adjustments With the rapid growth in demand for magnesium alloys in the downstream sector of magnesium metal, the market landscape is evolving rapidly. For instance, technological iterations in die-casting equipment, differences in the penetration rate of thick and thin magnesium alloy die-cast parts, and recycling rates, among other multidimensional factors, have a significant impact on the production of recycled magnesium. To promptly address the industry's need for supply-demand pattern analysis amid its rapid development, adjustments have been made to the data collection standards for "recycled magnesium production," "primary magnesium production," and "total magnesium metal demand," with historical data also being revised. Previous data collection did not account for the supply of recycled magnesium, which could lead to significant deviations in supply estimates. As the SMM Magnesium Database becomes increasingly comprehensive and detailed, a more robust model has been established. Adjustment Details - Data Source Upgrade: Upgraded from a single primary magnesium market supply and demand dataset to the establishment of a dual supply-demand model for magnesium metal, encompassing both primary and recycled sources. - Revision Scope: Historical data from January 1, 2023, to the present (including retrospective revisions and future forecasts). Effective Date From October 30, 2025 SMM Information & Technology Co., Ltd. SMM Magnesium Research Team Jiao Jiani 021-20707954 October 27, 2025
