​ * These percentages reflect the ownership currently in effect upon the completion of the reorganization in China and the ownership in effect upon the completion of the new capital funding by private equity investors in January 2021. ​ ** In preparation for Tongmei’s application for a listing of shares in an IPO on the STAR Market, in late December 2020 we reorganized our entity structures in China. JinMei and BoYu and their subsidiaries, previously organized under AXT, Inc., were assigned to Tongmei and effectively merged with Tongmei although they retained their own respective legal entity status and are wholly owned subsidiaries of Tongmei. The 33% minority interest stakeholders of BoYu converted their ownership to a 7.59% minority interest in Tongmei. The 8.5% minority interest stakeholders, employees of JinMei, converted their ownership to a 0.38% minority interest in Tongmei. Further, a number of employees, key managers and contributors, purchased a 0.4% minority interest in Tongmei. In 2020, the Investors transferred approximately $48.1 million of new capital to Tongmei. An additional investment of approximately $1.5 million of new capital was funded in early January 2021. Under China regulations these investments must be formally approved by the appropriate government agency and are not deemed to be dilutive until such approval is granted. The government approved the approximately $49 million investment in its entirety on January 25, 2021 at which time the Investors owned a redeemable noncontrolling interest in Tongmei of 7.28%. As of June 30, 2024, Tongmei’s noncontrolling interests and redeemable noncontrolling interests totaled approximately 14.5%. AXT remains the controlling stakeholder of Tongmei and holds a majority of the Board of Director positions of Tongmei. ​ *** In February 2021, Tongmei signed a joint venture agreement with certain investors to fund ChaoYang XinMei. ​ **** In April 2022, ChaoYang JinMei signed a joint venture agreement with certain investor to fund a new company, ChaoYang ShuoMei. ​ ***** In April 2022, Tongmei signed a joint venture agreement with certain investors to fund a new company, ChaoYang KaiMei. ​ ****** In May 2023, we sold 15% of our equity investments in Jia Mei to a third party. We now own 10% of Jia Mei and account for it under the fair value method.
