Announcement on Abnormal Fluctuations in Stock Trading

Our company and all members of the board of directors guarantee that the information disclosure is true, accurate, and complete, with no false records, misleading statements, or major omissions.

1. Overview of Abnormal Stock Trading Fluctuations

Shenzhen Zhaochi Co., Ltd. (hereinafter referred to as “the Company”)’s stock (Stock Name: Zhaochi Co., Ltd.; Stock Code: 002429) experienced a cumulative deviation of over 20% in closing prices for three consecutive trading days on March 11, 2026, March 12, 2026, and March 13, 2026. According to the relevant regulations of the Shenzhen Stock Exchange’s Stock Trading Rules, this constitutes an abnormal stock trading fluctuation.

2. Company’s Attention and Verification

In response to the abnormal stock trading fluctuations, the company has conducted verification in accordance with relevant regulations and inquired with the controlling shareholder and actual controller. The verification results are as follows:

1. The information previously disclosed by the company does not require supplementation or correction.

2. The company has noticed that market attention to MicroLED-related concepts is high. The company’s main business remains unchanged. Currently, the application of MicroLED in fields such as optical communication is in the sample verification and testing stage, and will not have a substantial impact on the company’s operating performance in the short term.

3. The company’s recent production and operation are normal, and there have been no significant changes in the company’s operating conditions or internal and external business environment.

4. The company, controlling shareholder, and actual controller have no major undisclosed matters related to the company, nor are there any major matters under planning.

5. During the period of abnormal stock fluctuations, the company’s controlling shareholder, actual controller, and persons acting in concert did not buy or sell the company’s stock.

6. The company has no violations of fair disclosure regulations.

7. On March 13, 2026, the company disclosed the “Progress Announcement on External Investment in Optical Communication Semiconductor Laser Chips and High-Speed Optical Modules Project” (Announcement No.: 2026-012), which introduced the latest progress of the company’s high-speed optical module and laser chip projects. As strategic emerging businesses, these projects are currently in the steady initial stage of production ramp-up, which requires a certain period for capacity expansion and market development. The optical communication business achieved revenue of 310 million yuan in the first half of 2025, accounting for less than 5% of the company’s total revenue of 8.483 billion yuan during the same period. Due to the early stage of development and relatively low revenue proportion, future growth will be affected by industry technological iterations, market competition patterns, and supply chain collaboration, among other factors, and carries certain uncertainties. Investors are advised to fully understand the company’s business structure and development stage, make rational investment judgments, and be aware of investment risks.
