China Daye Non-Ferrous Metals Mining (HKG:0661) expects a 44% year-over year decline in profit for 2025 to 5.4 million yuan, according to a Friday Hong Kong bourse filing.
Shares of the copper seller were down 30% in Monday afternoon trading.
On the other hand, annual revenue is expected to increase by 14% to 66.1 billion yuan.
The firm attributed the forecast to the two-way effect of the concentrated and accelerated release of domestic and foreign smelting capacity and the tight supply of copper concentrate.
