Dear User, Greetings! In recent years, the rare earth-NdFeB magnetic material industry chain has been continuously developing. During the process of refining its industry chain, SMM identified that the existing NdFeB-related data in the original terminal could no longer meet market demands. Therefore, after multiple rounds of surveys and verification, SMM has revised and expanded its original NdFeB data. The specific adjustments are as follows: NdFeB Production: 1. Discontinued 1 data point, namely the Monthly NdFeB Magnet Output by Manufacturer. The discontinued data location: Rare Earth - Rare Earth Production – NdFeB Magnet. 2. Added 5 data points, respectively [National Monthly Total Production], [Monthly Total Production of Sample Enterprises], [Monthly Production of Top-Tier Enterprises], [Monthly Production of Mid-Tier Enterprises], [Production Volume of Marginal Enterprises per Month]. The above data locations are all under Rare Earth - Rare Earth Production – NdFeB Magnet. 3. The above data are all updated monthly, with the update date being the last working day of each month, and the data dimension being the current month's data. 4. The data start date is January 2025. NdFeB Operating Rate: 1. Added five data points: [National Average Operating Rate], [Average Operating Rate of Sampled Enterprises in the Current Month], [Operating Rate of Top-Tier Enterprises in the Current Month], [Operating Rate of Mid-Tier Enterprises in the Current Month], [Operating Rate of Marginal Enterprises in the Current Month]. 2. The above data are located under Rare Earths - Rare Earth Operating Rate – NdFeB Magnet. 3. These data are updated monthly, with the update date being the last working day of each month, reflecting the current month's data. 4. The data series begins in January 2025. NdFeB Capacity 1. Added new category: Rare Earth - Rare Earth Capacity 2. Added four data points: [Quarterly Total NdFeB Capacity in China], [Quarterly NdFeB Capacity of National Top-Tier Enterprises], [Quarterly NdFeB Capacity of Mid-Tier Enterprises Nationwide], [Quarterly NdFeB Capacity of Small-Scale Enterprises Nationwide] 3. Location of the above data: Added new category: Rare Earth - Rare Earth Capacity 4. The above data is updated quarterly, with the update date being the last working day of the final month of each quarter. The data dimension reflects the current quarter. 5. The data start date is March 2025. NdFeB Supply-Demand Balance 1. Discontinued 3 data series: [SMM NdFeB Supply-Demand Balance: Supply], [SMM NdFeB Supply-Demand Balance: Consumption], [SMM NdFeB Supply-Demand Balance: Supply-Demand Balance] 2. Added 3 data series: [SMM NdFeB Supply-Demand Balance: National Total Supply], [SMM NdFeB Supply-Demand Balance: National Total Consumption], [SMM NdFeB Supply-Demand Balance: National Total Supply-Demand Balance] 3. Data location: Rare Earth - Supply-Demand Balance - NdFeB 4. These data series are updated monthly on the last business day of each month, reflecting the previous month's data (e.g., July data updated on August 29). 5. Data coverage starts from January 2025. Pr-Nd Alloy Supply-Demand Balance 1. Added a new classification for Pr-Nd alloy supply-demand balance 2. Added three datasets: [SMM Pr-Nd Alloy Supply-Demand Balance: Supply], [SMM Pr-Nd Alloy Supply-Demand Balance: Consumption], [SMM Pr-Nd Alloy Supply-Demand Balance: Supply-Demand Balance] 3. Data location: Rare Earth - Supply & Demand Analysis - Pr-Nd Alloy 4. The above data is updated monthly, with the update date set as the last working day of each month, reflecting the current month's data 5. The data series starts from January 2025 NdFeB Production and Operating Rate Forecast 1. Discontinued two data series: [Production - Forecast] and [Operating rate - Forecast]. 2. These will be replaced by two alternative data series: [NdFeB - Monthly production schedule expectation] and [NdFeB - Monthly operating rate expectation]. The above data adjustments will officially take effect on September 10, 2025. Users can then query the aforementioned data in the SMM data terminal.

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 Customer, To keep pace with the rapid development of the recycled copper raw materials industry and meet the market's demand for in-depth analysis of the recycling industry and the supply-demand pattern of copper cathode, our company has conducted a comprehensive optimization of the data model. We are now systematically upgrading and adjusting the standards and content of China's monthly supply-demand balance data for recycled copper raw materials, with the following treatment applied to historical data: I. Adjustments This upgrade primarily optimizes and updates the following indicators in the balance table: "Supply of Old Scrap from Recycled Copper Raw Materials," "Supply of New Scrap from Recycled Copper Raw Materials," "Processing Volume of Recycled Copper Raw Materials," and "Smelting Volume of Recycled Copper Raw Materials." (Data modification path: Database > Copper > SMM Recycled Copper > Monthly Supply-Demand Balance Table for Copper Scrap) II. Historical Data Treatment Historical monthly supply-demand balance data for recycled copper raw materials will no longer be updated starting from September 2025. Subsequent data will be uniformly released under the new standard, with the revised data retroactively applied from January 2025. Should you have any questions, please feel free to contact the SMM Customer Service Team. Thank you for your continued support and trust! IV.
