Do-Fluoride Chemicals Co LtdRegulatory letter for omitted disclosure of low-impact hydrofluoric acid business, potentially affecting share prices.

The Shenzhen Stock Exchange issued a regulatory letter to Do-Fluoride New Materials on August 4, 2026, pointing to a major omission in its information disclosure. In an investor relations activity record released on June 26, the company disclosed a semiconductor-grade hydrofluoric acid capacity of 40,000 tonnes, a market price increase of 20 to 30 percent, and bulk supply to leading manufacturers such as TSMC, Samsung, Hua Hong, and ChangXin Memory Technologies, while stating that profitability was well supported. However, it failed to simultaneously explain that the business accounted for less than 2 percent of sales in 2025 and the first quarter of 2026 and would not have a material impact on company performance. The Shenzhen Stock Exchange determined that this omission could significantly affect share prices and derivatives trading, violating relevant provisions of the Stock Listing Rules as revised in 2026, and required the company and all directors, supervisors, and senior management to learn from the incident and strictly fulfill their information disclosure obligations.
