Dingtong Communications: Stock price has experienced abnormal fluctuations. Expected net loss of 5.4-6.4 billion yuan in 2025.

Dingxin Communication announced that the closing price of the company's stock deviated by more than 20% for three consecutive trading days from March 9 to March 11, 2026, which constitutes abnormal volatility. After self-inspection, it was found that the controlling shareholder and the actual controller did not have any undisclosed significant matters. The core business of the company remains unchanged, but the bidding and tendering at the provincial and national levels are yet to be restored. A previous announcement estimated a net loss attributable to shareholders of the listed company in 2025 to be between -5.4 billion yuan to -6.4 billion yuan, and the shareholder Wang Tianyu, who holds more than 5% of the shares, has not completed the planned reduction of holdings.
