According to the Zhitong Finance App, Dinglong Co., Ltd. (300054.SZ) released a performance forecast for the first three quarters of 2026. Net profit attributable to shareholders of listed companies is expected to be 840 million yuan to 860 million yuan in the first three quarters, an increase of 61.72% to 65.57% over the previous year. Benefiting from the boom in the downstream semiconductor and new energy lithium battery industry and increasing market share, downstream customer demand is strong, and the company's product orders have grown rapidly. The details of the core product business are as follows:
(1) CMP polishing pads: Product sales revenue in the first three quarters of 2026 was about 1,136 million yuan, up 43% year on year; of these, product sales revenue was about 391 million yuan in the third quarter, up 22% year on year and 6% month on month. Shipments of polishing pads reached a record high in a single month in September; large-scale production expansion projects for hard pads and soft pads are being built according to plan, respectively.
(2) CMP polishing liquid and cleaning solution: Total product sales revenue for the first three quarters of 2026 was about 333 million yuan, an increase of 64%; of these, the third quarter achieved product sales revenue of about 139 million yuan, an increase of 65% year on year and 29% month on month. The amount of polishing liquid released in the copper barrier layer has increased significantly; the loading rate of self-produced grinding particles in the polishing liquid has exceeded 80%.
(3) High-end wafer photoresists: Achieved product sales revenue of approximately RMB 10.24 million in the first three quarters of 2026. The company has now obtained customer orders for 10 high-end wafer photoresist products. Shipments increased steadily in the third quarter to achieve stable supply, and product quality stability is at a high level in the industry. Research and development of auxiliary materials for lithography is progressing in an orderly manner, and 6 products have been laid out. Two of these mainstream products are scheduled to be launched on the market in the fourth quarter, which is expected to become a new growth point for the high-end wafer photoresist business.
(4) New energy lithium battery functional auxiliary materials business: From the company's beginning in March 2026 to the end of the third quarter of 2026 (that is, March to September 2026), the new energy lithium battery functional auxiliary materials business achieved product sales revenue of about 463 million yuan, an increase of 59% year on year; of these, the third quarter increased 59% year on year and 17% month on month. Overseas markets have expanded smoothly, and small-batch shipments have been achieved to overseas customers; next-generation dispersants have been successfully introduced and supplied to leading customers, and the product structure has been continuously optimized, laying the foundation for continued business growth.
(5) Semiconductor display materials: Product sales revenue of about 343 million yuan was achieved in the first three quarters of 2026. Affected by factors such as insufficient downstream capacity utilization rate and the overall recovery pace of the industry falling short of expectations, the company's semiconductor display materials business performance was under pressure in the short term. However, the market share of related products and the coverage of new products have continued to increase, and the long-term competitiveness of the business has been further consolidated.
