Tiannai Technology plans to sell 51% of BVI's shares in Tiannai, which controls the US business, to Aether Materials Limited, controlled by Zheng Tao, the controlling shareholder and one of the actual controllers, for US$25.5 million. After the transaction is completed, BVI Tiannai will no longer be included in the consolidated statements of listed companies, and the North American business originally controlled by the listed company will be taken over by the relevant party of the actual controller. According to the announcement, the purpose of this adjustment is to enable the US to meet the certification requirements of the relevant US laws for non-PFE subjects. In the future, Tiannai Technology also plans to continue to reduce its shares in BVI Tiannai, so that a single Chinese entity holds no more than 25% of the shares, and multiple Chinese entities hold no more than 40% of the total shares. According to the Tianyancha App, Tiannai Technology currently has 12 domestic and foreign investors, 9 of which are active or in business, including Changzhou Tiannai Materials, Tiannai Materials, and Zhenjiang Xinna Materials. Tianyancha's investment relationship further shows that the proposed sale is a BVI entity that controls the US business, and domestic materials companies are not included in the scope of the transaction. This means that this adjustment mainly focuses on the North American business control chain and is not an overall divestment of the domestic materials business. Meanwhile, Tiannai Technology previously provided a guarantee of 159.5 million yuan to Tianna of the United States. After the transaction was completed, the guarantee for the subsidiary will be changed to a guarantee for the controlling shareholder and its related parties. Equity control, the scope of consolidated statements, and guarantee relationships will change simultaneously in the same transaction, and the impact of the transaction extends from equity disposal to the linked guarantee structure.
