Dear User, In order to enhance the accuracy and reference value of our data services, and based on comprehensive research and evaluation, SMM has decided to optimize and adjust the historical data related to ternary precursors. This adjustment involves the removal of certain redundant capacity data, with corresponding data points being updated accordingly. The specific scope of the adjustment is as follows: The aforementioned data updates will officially take effect on December 10, 2025 . Should you have any questions regarding this adjustment or require further clarification, please feel free to contact us at any time: Thomas Feng, Senior Research Manager, Nickel Industry Research Department (Phone: 021-51666714, Email: fengdisheng@smm.cn) Yizhou Wang, Ternary Precursor & Ternary Cathode Analyst, Nickel Industry Research Department (Phone: 021-51595909, Email: wangyizhou@smm.cn). Thank you for your continued attention and support for SMM. Nickel Industry Research Department Shanghai Metals Market December 1, 2025

Dear User, To further optimize the SMM ternary cathode precursor data service and better align it with market demands, we are adjusting the naming of certain monthly ternary precursor output data points. The specific changes are as follows: Additionally, to more precisely meet customer needs, we are now splitting the monthly output data for 7-series, 8-series, 9-series, and NCA ternary precursors, providing independent data for each series. The newly added and adjusted data points are as follows: Based on the above adjustments, the data points for the monthly output forecast values of ternary precursors have been simultaneously updated. The specific changes are as follows: Thank you for your continued attention and support for SMM's new energy and nickel data services. SMM Information & Technology Co., Ltd.

Dear Useres, With the deep reshaping of the new energy industry chain, the strategic position of sulphur, a traditional bulk raw material, is undergoing a fundamental transformation. Historically, price fluctuations in sulphur-sulphuric acid primarily affected traditional industries such as phosphate fertilisers and titanium dioxide. However, as lithium iron phosphate (LFP) has become the mainstream cathode material for power batteries, the production of its core precursor, iron phosphate, heavily relies on high-purity phosphoric acid, which in turn uses sulphuric acid as its raw material. This enables price fluctuations in the sulphur-sulphuric acid chain to be directly and rapidly transmitted to the cost of LFP. Similarly, in areas such as nickel-cobalt smelting and precursor preparation, sulphuric acid is a key auxiliary material, and its price directly impacts the cost of products like battery-grade nickel sulphate and cobalt sulphate. The emergence of new demands: Sulphur itself, as a key sulphur source for lithium sulphide and sulphide solid-state electrolytes (such as LPSC), is seeing its material purity and supply stability begin to attract attention from cutting-edge battery technology R&D. As an authoritative information institution long dedicated to the non-ferrous metals and new energy materials sectors, SMM, after a period of consolidation and market surveys, plans to introduce new sulphur price points starting December 12, aiming to provide the market with more precise pricing anchors and price references. The specific new price points are as follows: Sulphur: Solid, Sulphur (S) content ≥99.0%, Price Description: Ex-factory price (buyer's self pick-up price), including 13% VAT.
