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. Specific specifications and descriptions are as follows: Price Point Names: TOPCon Module-182mm-CIF Malaysia TOPCon Module-210mm-CIF Malaysia TOPCon Module-210R-CIF Malaysia Price Description: Price Type: CIF Major Ports in Malaysia Tax Standard: Tax-excluded Definition: CIF Price for Major Ports in Malaysia Unit: $/W Leading Brands: LONGi Green Energy Technology Co., Ltd., Jinko Solar Co., Ltd., Trinasolar Co., Ltd., JA Solar Co., Ltd., CSI Solar, CHINT Group Co., Ltd., etc. Minimum Trading Volume: 10 MW Delivery Period: Within 3 months Release Time: Every Friday at 11:00 AM Beijing Time Payment Terms: Cash, and other payment methods standardized to cash SMM PV Research Team January 13, 2026

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.

Dear users, On August 29, 2025, the State Administration for Market Regulation and the Standardization Administration of China jointly issued the "Secondary Lead Ingot (GB/T 21181-2025)" (hereinafter referred to as the "new national standard"), which will officially take effect on March 1, 2026. Compared to the "Secondary Lead and Lead Alloy Ingot (GB/T 21181-2017)" (hereinafter referred to as the "old national standard"), the new national standard revised the scope. It changed from "This standard applies to secondary lead and its alloy ingots produced by smelting and processing using lead-containing scrap as raw material, mainly used in batteries, alloys, chemical industry, and other fields" to "This document applies to secondary lead ingots produced by pyrometallurgical smelting and processing using waste lead-acid batteries and recycled lead and lead alloy materials as raw materials, mainly used in lead-acid batteries, alloys, chemical industry, and other fields." Regarding secondary lead grades, the ZSPb99.994 and ZSPb99.992 secondary lead ingot grades were deleted the ZSPb99.990, ZSPb99.986, and ZSPb99.983 secondary lead ingot grades were added. Details are as follows: With the development and changes in the secondary lead industry, the actual production and use of secondary lead in the market in recent years have already diverged significantly from the old national standard. In addition to changes in the main element lead content, the bismuth (Bi) content has also undergone substantial changes. According to SMM's understanding of major producers and users of secondary lead, the distribution by bismuth content usage is as follows: enterprises using bismuth content ≤0.008% account for about 15% those using ≤0.012% account for about 60% and those using ≤0.015% account for about 25%. Furthermore, based on its price assessment methodology, SMM solicited market suggestions on the specifications for the secondary refined lead price. Market feedback recommended that the price collection standard for SMM's secondary refined lead price reference the new national standard for secondary lead, with grade ZSPb99.99 accounting for 24%, grade ZSPb99.986 for 66%, and grade ZSPb99.983 for 10%. Considering that the current actual usage in the secondary lead market covers the three grades specified in the new national standard for secondary lead, SMM will define the specifications for the national and regional prices of secondary refined lead as ZSPb99.983-99.99%, based on real market transaction conditions. The new standard will be officially implemented from January 1, 2026, serving as the reference standard for SMM's price assessments. During this period, SMM will continue to collect suggestions and feedback from all parties, closely follow changes in the lead industry chain market, and identify and optimize SMM prices to better serve the industry!
