SMM plans to officially launch the Thailand Zamak3 Premium.

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 User, Greetings! To assist secondary aluminum enterprises in accurately grasping the regional supply-demand pattern within the domestic market, obtaining real-time spot aluminum scrap price information from core production areas, effectively reducing information barriers and communication costs in transaction processes, and further improving the price system and research dimensions of the secondary aluminum industry chain, SMM, after multiple rounds of market surveys and data accumulation, plans to revise the content of the original price points. The specific update arrangements are as follows for market reference. Explanation of Modifications to the Original Aluminum Scrap Price Points: The content changes for the following four price points—Shredded Aluminum Tense Scrap (Foshan), Shredded Aluminum Tense Scrap (Anhui), Shredded Aluminum Tense Scrap (Changege), and Shredded Aluminum Cast Scrap (Foshan)—only involve supplementary modifications to the names, specifications, and definitions of the previous price points and do not affect the reference and viewing of corresponding historical prices. 1. Price Point Name: Shredded Aluminum Tense Scrap (Foshan) revised to Shredded Aluminum Tense Scrap Liquid Aluminum Price (Foshan) Specification: Water yield rate 90-93% revised to Water yield rate 90-93%, Copper >1.5% Definition: Transaction price, self pick-up price at goods yard revised to Liquid aluminum price, settled based on actual metal yield, guidance price for self pick-up at goods yards in the Foshan area. 2. Price Point Name: Shredded Aluminum Tense Scrap (Anhui) revised to Shredded Aluminum Tense Scrap Liquid Aluminum Price (Anhui) Specification: Water yield rate 90-93% revised to Water yield rate 90-93%, Copper >1.5% Definition: Transaction price, self pick-up price at goods yard revised to Liquid aluminum price, settled based on actual metal yield, guidance price for self pick-up at goods yards in the Anhui area. 3. Price Point Name: Shredded Aluminum Tense Scrap (Changege) revised to Shredded Aluminum Tense Scrap Liquid Aluminum Price (Changege) Specification: Water yield rate 90-93% revised to Water yield rate 90-93%, Copper >1.5% Definition: Transaction price, self pick-up price at goods yard revised to Liquid aluminum price, settled based on actual metal yield, guidance price for self pick-up at goods yards in the Changege area. 4. Price Point Name: Shredded Aluminum Cast Scrap (Foshan) revised to Shredded Aluminum Cast Scrap Liquid Aluminum Price (Foshan) Definition: Transaction price, self pick-up price at goods yard revised to Liquid aluminum price, settled based on actual metal yield, guidance price for self pick-up at goods yards in the Foshan area. Effective Time: The modifications to the aforementioned price points will be officially released starting November 12, 2025, and updated every working day. This revision aims to more accurately reflect market price levels through more refined grade classifications and provide market participants with more targeted decision-making references.
