We have already successfully harvested the first batch of polysilicon produced in the new facility. It is a great achievement for us to complete the project ahead of schedule given the significant difficultiesand challengesresulting from the resurgence of COVID-19. This would not have been possible without the dedication and expertise of our outstanding team and various suppliers who haveset up a new benchmark of excellence for the Company and theindustry.

"2021 is a milestone in the solar PV history when grid parity has been broadly achieved. The urgency to tackle climate change has led to broad policy support from major economies globally. With the rising prices of fossil fuels,solar PV is becoming more competitive and its economic value is being increasingly recognized by the market,as reflected by the increased prices of solar products this year,a rare occurrence inthe solar PVhistory. We believe we are just at the beginning of a new era in which solar PV will play an increasingly critical role as one of the cleanest,most sustainable,and most cost-effective sources of energy. We expect to see accelerating growth in solar demand in the foreseeable future."

"As one of the first-tier high-quality polysilicon providers,we willcontinue toexecute our three-year plan toexpand our production capacity to 270,000MT by the end of 2024,to meet the world's urgent need for cost-effective and clean non-carbon energy generation. At the same time,we will continue to improve our product quality to be market-ready for the next generation N-typetechnology. With the proceeds from the successful IPO of our subsidiary,Xinjiang Daqo,on China's A-share market,our proven strong execution capabilities,deep understanding of our customers' needs,and our advantages in cost structure and product quality,we have a strong foundation to continue to serve the fast-growing solar PV market and create value for our shareholders."
