Hubei HYYQ Gas Co., Ltd.

Announcement on Abnormal Fluctuations in Stock Trading

The Company and all members of its Board of Directors guarantee the truthfulness, accuracy, and completeness of the information disclosed, and are free from any false records, misleading statements, or material omissions.

Special Reminder:

In response to recent market concept speculation and false rumors, the Company hereby clarifies as follows:

1. Most of the Company's electronic specialty gas products are currently in the trial production phase. Only a few products such as electronic-grade carbon monoxide, high-purity ammonia, carbonyl sulfide, and silane have achieved sales, accounting for less than 5% of sales revenue. The electronic specialty gas business faces significant uncertainties such as long validation cycles and high customer access barriers, rendering market rumors unreliable.

2. Major products such as electronic-grade tungsten hexafluoride are still in the trial production phase. The capacity ramp-up time and capacity release cycle are relatively long. Downstream certifications have not yet been obtained, and no legally binding substantive order agreements have been signed. No tungsten hexafluoride products have been exported, and no performance has been generated. It is expected that this will not have a significant impact on the Company's operating performance in the next 2-3 years.

3. As of July 1, 2026, the Company's trailing P/E ratio was 270.12 times, far exceeding the industry average of 29.30 times, indicating a severely overvalued stock. In the past 30 consecutive trading days, the cumulative increase in the Company's stock price has deviated by more than 100%, seriously deviating from its fundamentals. This indicates market overheating and irrational speculation, with a high risk of short-term price decline.

4. The Company solemnly reminds all investors that all information should be based on the official announcements published on the Shenzhen Stock Exchange website and in the Securities Times, China Securities Journal, Securities Daily, and Cninfo.com.cn. Do not believe false online rumors, make rational decisions, and be aware of the risks of speculation in the secondary market!
