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

Dear Industry Peers, Hello! Electrolytic manganese metal (EMM) is a key raw material for manufacturing products such as stainless steel, specialty alloys, and battery materials. Europe, as a major global hub for stainless steel production, high-end manufacturing, and the new energy industry, is also one of the core consumer markets for EMM. Its price dynamics significantly influence the global market structure and pricing. Based on Rotterdam’s status as Europe’s largest port, which aggregates raw materials from major production regions worldwide and facilitates the circulation of spot cargo within the region, it has developed a mature storage, logistics, and trading network. The prices there accurately reflect the arrival costs in the European market, the supply-demand balance, and regional premiums, providing market participants with a critical benchmark for price reference. To proactively address market shifts, meet the ​​pressing need for price discovery​​ of Rotterdam warehouse electrolytic manganese metal, and enhance market transparency, SMM has decided: Commencing December 23, 2025, SMM will officially launch a new price: SMM Electrolytic Manganese Metal, in-whs Rotterdam, USD/mt Details of this price point are as follows: Description:SMM Electrolytic Manganese Metal, in-whs Rotterdam, USD/mt Quality:Mn99.7% Quantity:Minimum 25 tonnes Definition: In-warehouse Rotterdam,duty-unpaid, customs uncleared Brand Listing:Tianyuan Manganese Industry, CITIC Dameng, Wuling Manganese Industry,etc Timing:1Months Unit:USD/mt Payment Terms:Cash, other payment terms normalized Pulication:Daily, by 11am Beijing Time (i.e., before 4:00 AM London Summer Time before 3:00 AM London Winter Time) SMM Nickel Industry Research Departmen December 16, 2025
