Dear Industry Peers, Imported manganese ore is a key raw material for manufacturing products such as silicomanganese alloy and ferromanganese alloy, with high-quality manganese ore being particularly favored by the market. Australian manganese ore is a mainstream and high-frequency oxide ore globally, serving as an important reference standard for global manganese ore pricing, and its price fluctuations directly impact the cost chain of global manganese-based alloys. Tianjin Port and Qinzhou Port are the main unloading ports for imported manganese ore in China. Equipped with complete storage facilities, these two ports feature high single-vessel unloading efficiency and large manganese ore reserve capacity. The formed complementary pattern of "Tianjin in the north and Qinzhou in the south" has enhanced China's bargaining power in global manganese ore trade. Prices at Tianjin Port (north) and Qinzhou Port (south) serve as benchmarks for global manganese ore pricing, which are referenced by both domestic and foreign ore merchants. To actively respond to market changes, meet the urgent demand of users for understanding the prices of Australian Mn42% manganese ore at Tianjin Port and Qinzhou Port, and improve the transparency of market information, SMM has decided: Commencing December 31, 2025, SMM will officially launch two new price: SMM Mn Ore, Australia Block 42%, In-whs-Tianjin Port, Yuan/ton-degree SMM Mn Ore, Australia Block 42%, In-whs-Qinzhou Port, Yuan/ton-degree Details of this price point are as follows: Description: SMM Mn Ore, Australia Block 42%, In-whs-Tianjin Port, Yuan/ton-degree Quality: Mn 42% Quantity: Min 100 tonnes Definition: EX-warehouse-Tianjin Port Brand Listing: South 32,etc Timing: Prompt Unit: Yuan/ton-degree Payment Terms: Cash on same day, other payment terms normalized Pulication: Daily, by 11am Beijing Time (i.e., before 4:00 AM London Summer Time before 3:00 AM London Winter Time) Description: SMM Mn Ore, Australia Block 42%, In-whs-Qinzhou Port, Yuan/ton-degree Quality: Mn 42% Quantity: Min 100 tonnes Definition: EX-warehouse-Qinzhou Port Brand Listing: South 32,etc Timing: Prompt Unit: Yuan/ton-degree Payment Terms: Cash on same day, other payment terms normalized Pulication: Daily, by 11am Beijing Time (i.e., before 4:00 AM London Summer Time before 3:00 AM London Winter Time) SMM Nickel Industry Research Department December 26, 2025

Dear User, Greetings! In recent years, the development of the secondary zinc industry has attracted significant attention however, the domestic supply of secondary zinc oxide has become increasingly tight. In contrast, Southeast Asia boasts abundant resources of secondary zinc oxide raw materials at relatively low prices, which has prompted many Chinese enterprises to establish production facilities in the region, with a considerable number choosing Vietnam. Meanwhile, amid growing uncertainties in international trade, an increasing number of companies are relocating their plants to Vietnam to achieve integrated procurement, production, and sales, gradually forming a market trend. To keep pace with the globalization of international trade and the market development of secondary zinc oxide both domestically and overseas, and to reflect the true price fluctuations of secondary zinc oxide in the global market, SMM plans to launch the CIF Imported Secondary Zinc Oxide Payable . The SMM CIF Imported Secondary Zinc Oxide Payable is an indicative price formed and published by SMM according to this methodology, which can be used by trading parties as a reference for settling secondary zinc oxide trades from Vietnam. This price reflects the mainstream price of the CIF Imported Secondary Zinc Oxide Payable​​​​​​​ for each month. The price will be officially launched on November 28, 2025, and historical prices can be viewed simultaneously on the SMM website (smm.cn). The price will be published by 18:00 on the last working day of each month. Price Definition: The mainstream transaction price of CIF Imported Secondary Zinc Oxide Payable in actual trades during the month. Going forward, SMM will continue to monitor changes in the zinc industry chain market, optimize SMM prices, and better serve the industry! For any inquiries regarding the price, please contact Zinc Analyst Hua Lin at 021-20707885 hualin@smm.cn. SMM Information & Technology Co., Ltd. Zinc Research Team November 21, 2025

Dear User, Greetings! The PV industry is currently accelerating its transition to N-type technology, with TOPCon modules emerging as a core product in major global markets due to their superior power density. Meanwhile, against the backdrop of increasingly complex global trade conditions and fluctuating international logistics costs, the market is demanding greater transparency in pricing information. Standalone FOB prices can no longer adequately meet the needs of upstream and downstream players in the industry chain for accurately calculating overseas landing costs. As CIF prices more directly reflect the actual competitiveness of products in target markets, their importance as a basis for trade settlement and a tool for risk hedging has become increasingly prominent. To better understand the actual CIF market conditions for module exports to Southeast Asia and help enterprises reduce transaction risks and costs amid complex trade dynamics, SMM, after a period of market observation and surveys, plans to officially add the following product prices starting January 23, 2026, as references for market transactions: TOPCon Module-182mm-CIF Malaysia TOPCon Module-210mm-CIF Malaysia TOPCon Module-210R-CIF Malaysia The published prices are all CIF prices for major ports in Malaysia.

SMM 1.8mm Tin-Plated Copper Rod Premium (Electroplating), Ex-works China, VAT included, yuan/tonne Methodology 1.1 SMM Price Assessment Methodology General Provisions Shanghai Metals Market (SMM) is a fully independent third-party service organization that does not participate in any actual transactions. Instead, it maintains close communication with buyers or sellers in the market as an observer or organizer and provides relevant services to the market. SMM continuously develops, reviews, and revises its methodology through communication with industry professionals, adopting the most common product specifications, trade terms, and trade conditions in the industry. Equal importance is given to normal transactions that meet the standard specifications. SMM reserves the right to exclude any price information deemed less reliable or unrepresentative from its price assessments. SMM publishes daily spot metal prices (or price indices, including those for the Chinese market, markets outside China, and global markets), commonly referred to as SMM prices. For each published SMM price, a corresponding methodology is established (all of which are available for reference on SMM’s official website, www.smm.cn). The methodology specifies the methods and procedures for generating and publishing SMM prices, and SMM strictly adheres to these guidelines when producing and releasing SMM prices. To align with the actual conditions of the spot market, SMM will make necessary revisions to the SMM price assessment methodology and announce these revisions on the official website www.smm.cn 28 days before their formal implementation.
