Yi Yuan Communications: Currently, the impact of US tariff policies on the company is limited and controllable.

On April 30th, Yiyuan Communication stated on its interactive platform that, so far, the US tariff policy has not had a significant impact on the company's operations. On the sales side, the proportion of the company's direct exports to the US as a percentage of its revenue in 2024 was 0.8%, which is relatively low. The company will actively respond to this through various measures such as business negotiations and overseas production. On the procurement side, the company's raw material procurement system has been globalized. In conclusion, the current impact of relevant tariff policies on the company is limited and controllable.
