Dear users, Hello! In recent years, the cesium and rubidium industry chain has undergone continuous changes. During SMM's ongoing research to improve the cesium and rubidium industry chain, it was found that there is a lack of market liquidity for cesium and rubidium metals despite quoted prices, and there are significant price spreads in market quotations. To reduce transaction risks and costs for upstream and downstream clients, after a period of deliberation and market consultation, SMM has decided to adapt to market development needs and suspend the timely updates of cesium and rubidium metal prices. The specific adjustments are as follows: 1. Suspension: "Cesium metal (Cs≥99.5%)", with the suspension date set for August 15, 2025 (working day). 2. Suspension: "Rubidium metal (Rb≥99.5%)", with the suspension date set for August 15, 2025 (working day). The above-mentioned price points that have ceased updates will be removed from the website quotation window. However, historical prices and these price points will still be retained in the database. If clients have any needs related to historical data, they can contact the SMM Minor Metal Research Team.

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 Users, To optimize the data structure and enhance your data retrieval and analysis efficiency, we will adjust the classification hierarchy of "Magnesium" data in our Database Pro, effective from February 1, 2026. Before Adjustment: After Adjustment: Reason for Adjustment: Sustained Growth in User Attention: We have observed that in recent years, user query frequency, analysis depth, and attention to magnesium-related data have significantly increased. This adjustment aims to respond to your needs, making the classification structure more aligned with your usage habits and enabling easier access and retrieval of relevant data. Impact and Recommendations for You: • Change in Data Access Path: After the adjustment, you can directly locate the "Magnesium" category under the Minor & Precious Metals classification directory in the database, without needing to access it through the "Minor Metal" category. • This adjustment will not result in any loss of historical data, nor will it affect data usage permissions it only changes the classification hierarchy. We believe this adjustment will provide you with a clearer and more efficient data service experience. We sincerely apologize for any inconvenience caused by this adjustment and greatly appreciate your understanding and support. SMM Information & Technology Co., Ltd. January 22, 2026
