Profit surge and China's anti-dumping duty on Japanese chip material lift Sanfu

First-half profit more than tripled Sanfu's first-half 2026 net profit jumped 209.73% to 119 million yuan, with revenue up 30.17% and second-quarter profit doubling from the first quarter. Stronger earnings make the shares more attractive to investors and support a higher price.
The profit surge is the main fundamental driver of the stock's value this period.
China's anti-dumping duty on Japanese dichlorosilane China imposed provisional anti-dumping deposits of up to 99.2% on dichlorosilane from Japan, a key chip-making chemical. This makes imported Japanese material much more expensive, so domestic buyers are likely to turn to Sanfu, which has 500 tonnes of electronic-grade capacity and plans to expand to 850 tonnes.
This new trade measure directly benefits Sanfu's domestic dichlorosilane business and triggered the limit-up move.
Cash flow weakens despite profit growth Operating cash flow fell 37.39% to 13.97 million yuan even as profit rose, meaning the company collected less cash from its sales. This is a real counterweight: if cash generation does not improve, the profit growth may be lower quality than it appears.
It is the main negative detail in the interim report and balances the otherwise positive earnings picture.

Strong H1 profit and buyback offset by insider selling and project delay

Chairman proposes share buyback The chairman proposed buying back 12–24 million yuan of shares, signaling confidence and supporting the price. Buybacks reduce shares outstanding and often lift investor sentiment.
This is a new capital action that directly supports the share price.
First-half profit jumps 49% Net profit rose 49.33% to 68.06 million yuan on 27.54% higher revenue, with a 1 yuan per 10 shares dividend. Strong earnings and cash flow improve the company's fundamental picture.
This is the core new financial result that shows improving profitability.
Controlling shareholders plan to sell up to 3% Some controlling shareholders and concert parties plan to sell up to 4.27 million shares (3% of total) within three months. This increases share supply and can pressure the price down.
This is a new negative capital event that creates a share overhang.
R&D center project delayed to Sept 2027 The raised-fund R&D center project is delayed by one year to September 2027, with investment progress at only 55.39%. The delay may raise doubts about execution and future growth.
This is a new operational setback that could weigh on investor confidence.
