Today, SMM's 7μm wet separator price was raised by 1.18% to 0.86 yuan/square meter. Institutions pointed out that the industry is entering a peak season, and the bargaining power of separator companies has increased. The market is overall in a tight balance, with industry inventory at historically low levels, and prices are expected to rise further. The growth rate of supply has significantly slowed down (27% in 2025, 8% in 2026), and there are no plans for new production capacity in the next two years, while planned projects can continue construction. The expansion cycle for separators is long, and supply growth from 2026 to 2027 will be lower than the growth rate of demand. Additionally, cutting the production lines of 7 and 9 microns to 5 microns results in capacity loss. If the downstream adopts 5 microns quickly, it will further exacerbate the capacity tightness of 7 and 9 microns. After the previous round of price increases, leading companies had a single square profit of 6-7 cents in Q4 2025, and around 10 cents in Q1 2026. The investment for wet separators per 100 million square meters is 200-300 million, and with a payback period of 5-8 years, the single square profit needs to exceed 30 cents, corresponding to a PE of 15 times for each company. Expanding separator production is challenging, with heavy capital expenditures. After experiencing the previous round of expansion, the success rate for cross-industry ventures is low. The industry is cautious about production, and it is currently in a transition period between liquid and solid states. It is expected that subsequent capacity will be released in an orderly manner, gradually moving towards a tight balance, with significant room for price increases.
