: As a result of adjustments in Russia's helium export control policies, there is a temporary impact on the timeliness of the company's helium supply.

Huatai Gas Announcement: After self-inspection by the company, according to relevant laws of the Russian Federation, helium has been included in the list of specific commodities. The list clearly states that to export helium to regions outside the Eurasian Economic Union, special permission from senior Russian government officials is required. As of now, the above-mentioned law has taken effect and due to adjustments in Russian helium export control policies, the related export permits and customs procedures have become stricter. Since Russia is the main source of helium procurement for the company, there may be a temporary impact on the timeliness of helium supply. Due to uncertainties in policy implementation and approval periods, it is difficult to accurately estimate the duration of the impact. The company will monitor and assess relevant policy trends. Apart from the above situation, the company's current production and operation activities are normal, and there have been no major adjustments in the market environment or industry policies, and internal production and operation order is normal.
