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.

Hengli profit surges, but US sanctions cloud outlook

First-half profit more than doubles Hengli expects first-half 2026 net profit of about 7.2 billion yuan, up 136% from a year earlier, already beating all of 2025. The company credits better industry supply-demand balance and wider product spreads, which directly boosts earnings and supports the stock price.
This is the core new financial result that explains the profit surge and is a major positive price driver.
US accuses Hengli of buying Iranian oil The US Treasury says Hengli's refining unit bought billions of dollars of Iranian oil and sanctioned that unit in April. Hengli denies it. This raises the risk of further US penalties, which could hurt the company's access to global markets and weigh on the stock.
This is a new regulatory and geopolitical risk that could pressure the stock price and is a key counterweight to the profit news.
Fluorochemical demand from AI adds a growth angle Hengli is benefiting from rising demand for fluorine-containing materials used in AI servers and liquid cooling, as the fluorochemical industry tightens supply and raises prices. This opens a new growth area beyond its traditional refining and petrochemical business.
This points to a new demand driver that could support future revenue and is a positive factor for the stock.
