On December 6, Oujing Science and Technology announced that the date of reaching the expected usable state of its project "Ningxia Quartz Phase II Project" was postponed to December 31, 2027. .

The announcement shows that by the end of November this year, the investment progress of Ningxia Quartz Crucible Phase I Project has reached 61.16%, the investment progress of semiconductor quartz crucible construction project has reached 15.71%, and the investment progress of supplementary liquidity project has been completed, while the "Ningxia Quartz Crucible Phase II Project" has not yet been implemented.
It is reported that. "Ningxia Quartz Phase II Project" has been shelved for two years. . On November 22,
2023, Oujing Science and Technology issued a prospectus for issuing convertible corporate bonds to unspecified targets, intending to raise 470 million yuan. It is used for " Ningxia Quartz Phase I Project", "Ningxia Quartz Phase II Project" and supplementary working capital projects. The total investment of

Ningxia Quartz Crucible Phase II Project is 435 million yuan , and a total of 329 million yuan is planned to be raised. A total of 18 quartz crucible melting lines are planned to be constructed: 8 lines are planned to be constructed in Phase I project and 10 lines are planned to be constructed in Phase II project; and automatic edge cutting, detection, cleaning and packaging equipment, intelligent storage and other supporting equipment and facilities will be introduced. After the completion of the two projects, the production capacity of solar grade quartz crucibles and semiconductor grade quartz crucibles will be 180000 per year .
According to the announcement at that time, The above investment projects are supporting TCL Zhonghuan's new Ningxia Yinchuan 50g W (G12) Solar Grade Monocrystalline Silicon Material Intelligent Factory (Crystal Phase VI) project and TCL Zhonghuan 2023 It is expected to increase the purchase demand of quartz crucibles for 40 GW crystal production capacity in the year. At the same time, it can also meet the needs of other downstream customers to expand production.
However, one year later, on December 26, 2024, Oujing Science and Technology announced that the photovoltaic market had changed dramatically, and the "Ningxia Quartz Phase II Project" had not yet been put into construction and was in a state of suspension. The project has been on hold for more than a year. Therefore, Oujing Science and Technology has re-demonstrated the project, and finally determined that the project meets its overall strategy and development needs. In March
2025, Oujing Science and Technology announced that in order to further enhance the company's R & D strength and better meet the company's future development needs, in line with the principle of maximizing the company's benefits and shareholders'interests, after careful study and discussion by the company's management, it is proposed to change some of the investment projects. The raised fund of RMB 100,409,000 yuan was transferred from the original raised fund project " Ningxia Quartz Phase II Project" with an investment amount of RMB 252,884,200 yuan. It is used for the construction of the new project " Semiconductor Quartz Construction Project". After
this change, the amount of proceeds to be used for the Ningxia Quartz Crucible Phase II Project was reduced to RMB152,475,200 .
