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

SMM Clarification Statement SMM Information & Technology Co., Ltd. (hereinafter referred to as "SMM" or "the Company"), as a professional spot market price reporting agency and information provider, has recently noticed the circulation of false information regarding the fairness of SMM's price assessment. To avoid market misunderstandings, maintain a healthy and transparent market environment, and protect the Company's legitimate rights and interests, SMM hereby makes the following solemn clarification and statement: I. The Difference Between Spot Prices and Futures Prices is a Normal Reflection of Market Mechanisms According to basic economic principles, spot prices reflect the immediate supply-demand relationship and deliverable transaction conditions of the underlying asset, while futures prices reflect market expectations for future supply and demand, including factors such as capital cost and carrying costs. Both follow the principle of "convergence at maturity," meaning that futures prices gradually converge towards spot prices as the contract expiration date approaches. Therefore, during the life of the contract, the difference between spot prices and futures prices, especially with far-month contracts, is a normal phenomenon under the market pricing mechanism. II. Historical Data Proves the Rationality of the Price Spread Structure To objectively present the facts, SMM has made a price spread analysis chart based on publicly available market data: The chart clearly shows that from September 2023 to 2025, the monthly price spread between the SMM battery-grade lithium carbonate average price and the GFEX lithium carbonate futures contract prices fluctuated between positive and negative territory, always remaining within a reasonable range, and exhibited a significant convergence trend as the contract expiration date approached. This fully aligns with the market rule of futures and spot price convergence. Comparing a certain periods' futures prices (especially those of far-month most-traded contracts) with spot assessment prices and concluding that there is a "consistent significant deviation" is fundamentally flawed in methodology and can easily mislead market judgment. Any behavior that selectively highlights short-term trends in the price spread without considering the broader context is partial and irresponsible, failing to reflect the overall market situation. III. Recent Market Risk Control Measures Recently, to maintain the stable operation of the lithium carbonate futures market and prevent potential risks, the Guangzhou Futures Exchange, in accordance with its risk management rules, issued multiple notifications consecutively between November and December 2025, implementing a series of risk control measures for relevant contracts, including adjustments to transaction fee standards and trading limits. These measures represent the exchange's commitment to fulfill its self-regulatory duties in accordance with the law during specific market periods, aiming to promote the steady development of the market. IV. The Emergence, Nature, and Harm of False Information It is noteworthy that during this sensitive period, when the aforementioned risk control measures were being intensively implemented, a significant amount of false information began circulating on the Internet. While such information varies in content, it shares an identical core narrative: False claims have been made that SMM’s prices "consistently and significantly deviate from fair value and futures prices" and that "there are illegal benefit-related connections with certain institutions". These claims are entirely groundless. The timing and manner of their dissemination indicate that their purpose is not professional discussion but rather an attempt to exert improper pressure on SMM by confusing the price logic of spot and futures markets, interfere with the neutrality of spot price assessments, and consequently potentially mislead market expectations and disrupt the normal relationship between futures and spot prices. SMM hereby solemnly declares that SMM is always committed to price discovery in the spot market, does not participate in any futures market trading operations, and resolutely maintains market order. V. The Compliance, Neutrality, and Supervision Mechanisms of SMM's Price Assessment As a professional market price assessment agency, SMM always adheres to the principles of neutrality, objectivity, and fairness. SMM's price assessment methodology strictly follows the International Organization of Securities Commissions (IOSCO) "Principles for Financial Benchmarks" and is subject to audits by independent third-party audit firms. In terms of internal governance, SMM has established a comprehensive firewall system to ensure that personnel and management involved in the price assessment process do not hold any related futures or spot positions, thereby eliminating conflicts of interest at an institutional level. SMM also has no history of any penalties from securities regulatory authorities for violations. We consistently maintain an open attitude towards market supervision based on facts. VI. Appeal to the Public SMM strongly condemns the recent malicious fabrication and dissemination of false information in the market, which damages SMM's commercial reputation and attempts to disrupt the order of the futures and spot markets, and has initiated legal proceedings to protect its rights. Currently, SMM is comprehensively and continuously collecting and preserving evidence related to the infringements. For suspected infringing acts, the Company will take all legal measures, including but not limited to reporting to relevant regulatory authorities and filing complaints with relevant online platforms, to resolutely pursue the legal liability of the infringing parties. SMM reserves the right to pursue all legal consequences against the relevant responsible parties. We once again call on all market participants to enhance their legal awareness and professional discernment capabilities, obtain information from authoritative channels, analyze the market rationally, resolutely resist and refuse to spread any unverified and unfounded rumors, and jointly maintain a fair, orderly, and healthy development environment for the industry chain.
