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 User, Currently, lithium carbonate prices are experiencing significant fluctuations, leading to markedly increased cost volatility for lithium metal, for which lithium carbonate serves as the primary raw material. To more promptly and accurately reflect market conditions for lithium metal, SMM plans to increase the publication frequency of prices for both industrial-grade lithium metal and battery-grade lithium metal from weekly updates to daily updates . The updates will be released at 12:00 PM Beijing Time on each working day for market reference: 1. Battery-grade lithium metal, Specification: Li≥99.9% 2. Industrial-grade lithium metal, Specification: Li≥99% We welcome more relevant enterprises across the industry chain to participate and support SMM in better serving new energy industry chain-related companies.

Against this backdrop, SMM will begin publishing the US Midwest DDP aluminum premium starting February 27, 2026. Through daily market communication, SMM will introduce ......

Dear User, As a key intermediate product in the lithium industry chain, lithium sulfate serves as a primary raw material for producing core lithium chemicals such as battery-grade lithium carbonate and battery-grade lithium hydroxide. Its supply and price influence the costs of downstream lithium battery materials and market operations. Currently, the lithium sulfate market lacks open and transparent representative price references. International trade and procurement pricing largely rely on bilateral negotiations, leading to issues such as information asymmetry and delayed price transmission. With lithium sulfate production from African lithium producers, represented by the Zimbabwe region, commencing and gradually entering the market, SMM has compiled and launched the " Africa Lithium Sulfate (CIF China) Price " to promote standardized and transparent pricing for African lithium sulfate and enhance the efficiency of the industry chain. This price aims to objectively reflect the market conditions of African lithium sulfate arriving at main Chinese ports. It will provide a reliable price benchmark for producers, traders, downstream enterprises, and financial institutions, supporting the standardized development and price discovery of the global lithium resources market. SMM's "Africa Lithium Sulfate (CIF China)" was officially launched today (January 21, 2026) . Details are as follows: Africa Lithium Sulfate (CIF China), Specification: Li₂SO₄·H₂O content ≥80% Product Name: Africa Lithium Sulfate (CIF China) Quality Standard: Li₂SO₄·H₂O content ≥80% Definition: CIF main Chinese ports Unit: $/mt Minimum Trading Volume: 60 mt Delivery Period: 2 months Release Time: Weekdays, 12:00 Beijing Time Payment Terms: Letter of credit, telegraphic transfer, or documents against payment other payment terms require separate negotiation. Welcome more relevant enterprises in the industry chain to participate and support SMM in better serving new energy industry chain enterprises.
