STOCKS | Yihao New Materials Flags Unusual Share Trading After Two-Day Surge

Yihao New Materials said its shares recorded an unusual trading move after the cumulative deviation in closing-price gains reached 30% over two consecutive sessions on June 15, 2026, and June 16, 2026. According to Jin10, the company said an internal review found no need to correct or supplement previously disclosed information, and that its recent production and operations, as well as internal and external business conditions, had not materially changed. The company said its controlling shareholder and actual controller had no undisclosed matters that should have been reported, and they did not trade the company’s shares during the period of volatility. Yihao New Materials also issued a risk reminder. It reported net profit attributable to shareholders of the listed company of -58.62 million yuan for 2025, with the loss widening 50.85% from 2024, and said overall performance was below the industry average. The company said certification progress for its HVLP copper foil was slower than some peers and remained in sample testing, analysis, and certification, with no revenue generated so far. It added that equipment installation and commissioning were under way for the second-phase 5,500-ton production line of its fundraising-funded project, an annual 10,000-ton high-precision electrolytic copper foil project, and that the start of production remained uncertain.
