Yunnan Tin's profit jumps, then a maintenance shutdown caps output
First-half profit guidance points sharply higher Yunnan Tin told investors it expected first-half 2026 net profit of 1.47–1.57 billion yuan, up 38%–48% from a year earlier. The gain came from running its plants more efficiently, making more metal, and selling into higher prices — all of which support the shares.
Sets up the profit growth that is the core positive driver for the stock this period.
Reported results confirm the strong growth The actual half-year report showed net profit of 1.504 billion yuan, up 41.6%, on revenue of 31.573 billion yuan, up 49.68%. The numbers landed near the top of the earlier guidance, and Yunnan Tin was named among the nonferrous-metal leaders in Shenzhen's strong reporting season.
Confirms the guided profit growth was real and places the company among the market's strongest half-year performers.
Asset write-offs cut reported profit by 445 million yuan Alongside the results, Yunnan Tin scrapped damaged or idle equipment worth 252 million yuan and wrote off 296 million yuan of long-term expenses. Together these one-time charges cut net profit by 445 million yuan, a real drag on the headline number even though they are not cash losses from normal operations.
The main counterweight to the strong profit report and a genuine hit to reported earnings.
Smelter maintenance pauses tin output for up to 45 days The Tin Branch will shut its smelting equipment from September 30 for routine maintenance lasting up to 45 days. That temporarily reduces the company's tin production and the metal it can sell, though management says the full-year plan already accounted for the stoppage.
A fresh supply-side event that could trim near-term output and sales.
