Chongda Technology: The company's AI server-related PCB revenue accounts for no more than 10%; PTFE substrate PCBs do not involve the high-speed server field; and there is no business relationship with Huawei Mate XT2 or the Kirin 9050 Pro chip.

Chongda Technology announced that the company's stock price deviation for three consecutive trading days on September 11, September 14, and September 15, 2026, cumulatively exceeded 20%, constituting abnormal stock trading fluctuations. Since August 2026, the company's stock price has cumulatively risen 90.50%, triggering abnormal fluctuations twice in September. As of September 15, the rolling price-to-earnings ratio was 104.98 times, higher than the industry average, posing risks of irrational speculation and rapid decline. The company's share repurchase matter of RMB 60 million to RMB 120 million was completed on September 10, with the first repurchase of 6.5463 million shares, accounting for 0.53% of total share capital, and a total transaction amount of RMB 120 million. There are currently no new repurchase plans. Upon verification, the company's AI server-related PCB revenue accounts for no more than 10%, PTFE substrate PCBs do not involve the high-speed server field, and there is no business relationship with Huawei Mate XT2 or Kirin 9050 Pro chips. The subsidiary Punowei packaging substrates do not involve processes such as hybrid bonding. In the first half of 2026, the company's revenue was RMB 4.330 billion, a year-on-year increase of 22.55%; net profit attributable to the parent company was RMB 152 million, a year-on-year decrease of 31.30%. Rising raw material prices have squeezed gross margins, and the effect of structural price increases remains uncertain. Upon verification, the company and its controlling shareholder and actual controller have no major undisclosed matters that should be disclosed, and during the period of abnormal fluctuations, none of the directors, supervisors, senior management, controlling shareholder, or actual controller traded the company's shares.
