Changyingtong said recent market reports claiming the company passed a factory audit by a strategic customer were untrue.
According to Jin10, the company issued an abnormal trading announcement after its shares recorded a cumulative decline deviation of more than 30% over three consecutive trading days on June 25, 2026, June 26, 2026, and June 29, 2026.
Changyingtong said revenue from its device polarization-maintaining optical fiber business accounted for less than 1% of total revenue so far, and that it had relatively few orders on hand, leaving the business limited in scale.
The company said it had not achieved further breakthroughs in applications for its device polarization-maintaining optical fiber and that the product had not been deployed at scale in communication scenarios such as co-packaged optics.
Changyingtong added that it had few orders on hand or intended orders for optical fiber used in the communications sector and had not recently added major new communications customers.
