Core Viewpoint - The phosphochemical industry is an essential raw material sector in the national economy, with products widely used in agriculture, food, pharmaceuticals, electronics, construction materials, and new energy [1] Group 1: Industry Outlook - By the second half of 2025, the lithium battery industry is expected to show significant recovery, with steady increases in production scheduling and operating rates across the entire industry chain [1] - The strong demand for phosphorus-containing materials is expected to drive consumption of upstream raw materials such as phosphate rock and high-purity phosphoric acid, supporting the recovery of the phosphochemical industry chain [1] Group 2: Resource Constraints - China has limited phosphate rock resources and strong environmental constraints, leading to a continuous tightening of domestic supply [1] - Phosphate rock is the core raw material for the phosphochemical industry, with China supporting nearly half of the global production with only 5% of the world's reserves, highlighting significant resource security pressures [1] Group 3: Market Dynamics - The long-term price center for phosphate rock is expected to remain high, with leading companies currently enjoying a gross profit margin of around 80% [1] - Downstream demand for phosphate fertilizers remains rigid, but its proportion is expected to decrease from 78% in 2015 to 54% in 2024; meanwhile, the consumption share of wet phosphoric acid is projected to increase from 7% in 2021 to 17% in 2024, partly driven by new energy demand [1]

Group 1 - The chemical sector is experiencing strong capital inflow, with the chemical ETF (159870) seeing a net subscription of 299 million units [1] - High prices of sulfuric acid and sulfur are impacting the cost of wet-process phosphoric acid, leading some wet-process phosphoric acid producers to potentially switch to lower-cost thermal phosphoric acid, which may increase the usage of yellow phosphorus [1] - The demand for phosphoric acid is expected to surge after the Spring Festival, but the production of yellow phosphorus may not keep pace with the increased demand, resulting in a supply-demand mismatch [1] Group 2 - Due to limited supply and a slight increase in demand, yellow phosphorus prices are likely to rise after the Spring Festival [2] - As of February 4, 2026, the CSI Sub-Industry Chemical Theme Index (000813) increased by 0.25%, with notable gains from companies such as Sankeshu (3.07%) and Hongda Co. (2.57%) [2] - The top ten weighted stocks in the CSI Sub-Industry Chemical Theme Index account for 44.82% of the index, including major companies like Wanhua Chemical and Yilong Co. [2]

Summary of Key Points from the Conference Call Industry: Yellow Phosphorus Sector Core Insights and Arguments 1. Current high prices of sulfur/sulfuric acid are impacting the cost of wet-process phosphoric acid, leading to wet-process phosphoric acid costs exceeding those of thermal phosphoric acid. This may result in some wet-process phosphoric acid companies temporarily shifting to the lower-cost thermal phosphoric acid, thereby increasing the usage of yellow phosphorus [1][3] 2. Following the Spring Festival, the demand for phosphoric acid is expected to surge due to the seasonal peak, but the production of yellow phosphorus may not keep pace with the increased demand, leading to a supply-demand mismatch [2][4] 3. The supply of yellow phosphorus has been constrained in recent years due to high energy consumption and safety concerns, making significant capacity expansion difficult in the short term [5] 4. The combination of a slight increase in demand and limited supply may lead to a price increase for yellow phosphorus after the Spring Festival [6] Notable Companies in the Yellow Phosphorus Sector 1. Recommended companies include: - Chengxing Co., Ltd. (the purest yellow phosphorus stock) - Yuntu Holdings - Yuntianhua - Xingfa Group [7]

Group 1 - The company currently has a thermal phosphoric acid production capacity of 150,000 tons per year, with plans to increase it to 225,000 tons per year by 2026 [2] - The company expects a production capacity utilization rate of over 70% in 2025 [2] - The rising sulfur prices make thermal phosphoric acid more cost-effective compared to wet phosphoric acid, leading the company to adjust production based on market conditions [2] Group 2 - The increase in thermal phosphoric acid production is expected to positively impact the market price of raw material yellow phosphorus [2]

Summary of the Sulfur Market Update and Outlook Industry Overview - The sulfur market in China is experiencing a continuous increase in consumption, projected to rise over 40% from 2020 to 2025, reaching 11.6 million tons [1][5] - Domestic sulfur production is significantly increasing, while import volumes fluctuate due to international factors [1][5] - Major producers like Zhenhai Refining and Chemical have faced production interruptions due to accidents, impacting overall supply [2] Key Insights and Arguments - **Supply and Demand Dynamics**: The primary reason for the expected price increase in sulfur in 2025 is the supply-demand imbalance. Domestic production is expected to grow from over 8 million tons in 2020 to over 11.6 million tons in 2025, but imports are projected to decline, particularly in Q3 2025 due to international supply shortages [2][18] - **International Market Influence**: The international market significantly impacts China's sulfur supply, with Central Asia accounting for about 18% of imports. However, geopolitical tensions and reduced inventories have led to decreased exports from these regions [6][8] - **Russian Market Impact**: The ongoing Russia-Ukraine conflict has created a supply gap in the Russian sulfur market, with major producers like the Astrakhan Gas Processing Plant planning maintenance that will reduce output [8][29] - **Middle East as a Stable Supplier**: The Middle East, particularly countries like Saudi Arabia and Qatar, has become a key stable supplier of sulfur, gaining pricing power following the Russian supply gap [11][10] Additional Important Content - **Future Trends**: The global and Chinese sulfur markets will continue to be influenced by changes in supply and demand relationships. New oil and gas processing plants and upgrades to existing facilities are expected to increase supply, but geopolitical risks may lead to price volatility [7][23] - **Regional Demand Variations**: Indonesia's nickel industry is expected to significantly increase sulfur demand due to expansions in battery material-related metal smelting [24][25] - **Downstream Consumption Changes**: The consumption of phosphate fertilizers is expected to decrease by about 700,000 tons in 2025, while the renewable energy sector is projected to see an increase of 200,000 to 300,000 tons, although some projects may not launch as planned due to high costs [18][19] - **Price Trends**: Historical price trends indicate significant volatility, with domestic prices expected to reach between 4,200 and 4,220 RMB by the end of 2025 due to increased downstream demand and supply constraints [15][16] Conclusion - The sulfur market is poised for significant changes driven by domestic production increases, international supply challenges, and evolving demand dynamics across various sectors. The interplay of these factors will shape pricing and availability in the coming years, with a focus on maintaining a balance between supply and demand to mitigate risks of price spikes and shortages.
