Dinglong profit surges on chip and battery materials demand
▲
First-half profit jumps 70% on semiconductor and battery materials Dinglong's first-half net profit rose 70.2% to 529 million yuan, with revenue up 11.2%. CMP polishing materials sold strongly and high-end wafer photoresist products began batch delivery. This shows the core chip-materials business is growing fast, which supports a higher share price.
It is the period's first hard evidence of strong earnings growth and explains what is driving it.
Nine-month profit guidance points to continued momentum Dinglong expects first-three-quarter net profit of 840-860 million yuan, up 62%-66%. Third-quarter profit of 311-331 million yuan would be up 11%-18% from the second quarter. The company credits strong chip and lithium-battery demand and rising market share, so growth is still accelerating.
It is the newest and most forward-looking signal of how much money the company is making.
Buyback puts cash back into shareholders' hands Dinglong repurchased 1.39 million shares for 96.97 million yuan, at prices of 64.7-75.44 yuan. A buyback reduces the number of shares outstanding and signals management thinks the stock is worth buying, which can lift the price.
It is a concrete capital action that directly affects supply of shares and investor confidence.
◆
No dividend and slower inventory turnover are the counterweight Despite the profit jump, Dinglong will pay no cash dividend this half, and inventory turnover fell 19% year on year, meaning goods sit longer before selling. These are real soft spots that temper the strong earnings story and could cap how much the stock rises.
It gives the fair counterweight to the bullish earnings and buyback news.

Electronic Chemicals Sector Gains Momentum, Driven by Domestic Substitution and AI Computing Demand
On July 9, the electronic chemicals sector rose 2.03 percent intraday. Shanghai Xinyang gained 9.22 percent, Ruilian New Materials rose 5.80 percent, Xingfu Electronics added 5.76 percent, Lite-On Optoelectronics climbed 5.61 percent, and Dinglong Shares advanced 3.74 percent. A research note from Everbright Securities noted that domestic fluorochemical companies are accelerating their deployment of new fluorinated materials. Electronic-grade hydrofluoric acid has broken through bottlenecks in ultra-clean, high-purity processes and passed certification at leading wafer foundries, entering a phase of large-scale volume production. At the same time, AI and high-performance computing are driving demand for liquid cooling, with high-performance fluorinated coolants such as perfluoropolyether occupying an irreplaceable position in immersion cooling. A report from China Merchants Securities pointed out that the electronic chemicals industry is benefiting from downstream demand recovery and accelerated domestic substitution. Demand for AI chips and high-bandwidth memory is driving wafer fabrication capacity release, pushing up consumption of wet electronic chemicals, and the market size is expected to expand non-linearly. A research note from TF Securities noted that the electronic chemicals industry will embrace dual opportunities of demand recovery and domestic innovation in 2026. China's market share of wet chemicals for integrated circuits remains far below the global level, leaving significant room for improvement in domestic substitution rates. Leading enterprises with high-end capacity and core purification technologies will continue to benefit.
