    Guodun Quantum Share Price Surge Before Trading Suspension Raises Insider Leak Concerns; Supervisor Warned by Anhui CSRC Over Spouse's Short-Swing Trading

    In March 2024, Guodun Quantum's share price rose sharply before a trading suspension to plan a major matter, prompting market questions about an insider information leak; the company responded that there was no information that should be disclosed but had not been. In May 2024, the Anhui CSRC found that the spouse of Zhang Aihui, chairman of the company's supervisory board, bought and sold company shares during a window period, constituting short-swing trading; it issued a warning letter to Zhang Aihui and recorded it in the securities and futures market integrity file. Impact and handling: In October 2025 the company again issued an announcement on abnormal stock trading fluctuations, saying no information leak had been found. Progress: regulatory measure. Parties involved: QuantumCTek Co., Ltd. and Zhang Aihui (chairman of the supervisory board). Scope: Guodun Quantum stock trading and the supervisor personally.
