Yibin Tianyuan: Subsidiary's annual production capacity of 25,000 tons of yellow phosphorus was transferred for a deal of 185 million yuan.

Yibin Tianyuan announced that its subsidiary Infinite Mining Phosphorus Chemical Factory will cease production on December 19, 2023. In order to revitalize idle intangible assets, the company openly listed for transfer the 25,000 tons/year yellow phosphorus production capacity quota, which was eventually acquired by Hebang Biotechnology for 185 million yuan. On November 25, 2025, the two parties signed the Property Transaction Contract, and Hebang Biotechnology will make the payment within 5 working days of the contract taking effect. The completion of this transfer also requires the approval of Ma Bian County for the public announcement of the withdrawal of the yellow phosphorus production capacity of Infinite Mining, which presents uncertainty. This transfer does not constitute a major asset reorganization and does not have a significant adverse impact on the company's financial indicators.
