Domestic prebaked anode prices have risen for the second consecutive month, reaching a near three-year high. A reporter from Cailian Press recently learned from the industry chain that a large electrolytic aluminum plant in Shandong raised its October 2026 prebaked anode procurement benchmark price by 400 yuan per tonne compared with September, implementing a cash price of 6,130 yuan per tonne. This marks the second consecutive monthly increase since the 100 yuan per tonne rise in August. Currently, prebaked anode market prices in the Shandong region have climbed to between 6,130 yuan and 6,430 yuan per tonne, up about 25 percent year on year, the highest since February 2023. The direct driver of this round of price increases is raw material costs. Coal tar pitch remains at elevated prices due to tight supply of high-temperature coal tar, while petroleum coke prices have also rebounded in some areas. Data from Longzhong Information shows that petroleum coke prices have risen from about 2,500 yuan per tonne at the start of the year to above 3,100 yuan per tonne by the end of September. Global downstream consumption continues to expand, and domestic demand in new energy sectors such as power batteries and energy storage remains strong, directly boosting domestic aluminum consumption and providing rigid support for prebaked anodes. As the world's leading commercial prebaked anode producer, Sunstone Development has 4.06 million tonnes of prebaked anode production capacity in operation in 2026, with an additional planned capacity of about 1.12 million tonnes under preparation. The company said that with cost control measures such as centralized petroleum coke procurement and intelligent blending, as well as scale advantages, its profit margin is expected to be further optimized.

Sunstone Development announced that the company plans to invest in the construction of a centralized steam supply and energy-saving carbon materials project in the Dongxing Industrial Park, Nandagang Management Area, Huanghua City, Hebei Province, with a preliminary estimated total investment of no more than 550 million yuan.

Guizhou Sunstone Shuangyuan Carbon Materials Co., Ltd. has increased its registered capital from 2 million yuan to 400 million yuan, a surge of 19,900 percent. The company recently underwent a business registration change, with Tang Hao stepping down as legal representative and Ren Chungao taking over, while Guizhou Aluminum Group Co., Ltd. was added as a shareholder. The company was established in July 2025, with a business scope covering the manufacturing and sales of graphite and carbon products, heat production and supply, and import and export of goods. It is jointly held by Sunstone Development and the aforementioned new shareholder.
