The Company expects the Phase 3B facility will ramp up to full production capacity and expand its total production capacity to 30,000 MT by the end of the first quarter of 2019.

Daqo New Energy Corp. (NYSE: DQ) ("Daqo New Energy", the "Company" or "we"), a leading manufacturer of high-purity polysilicon for the global solar PV industry, today announced that it has completed the construction and installation of its Phase 3B polysilicon production facility in Shihezi, Xinjiang and has begun pilot production. The Company expects the Phase 3B facility will ramp up to full production capacity and expand its total production capacity to 30,000 MT by the end of the first quarter of 2019.

Once Phase 3B has reached full production capacity, a power purchase agreement with the local electric utility will reduce the Company's electricity rates by approximately 18% from the current levels, further lowering the Company's polysilicon production cost. With lower electricity rates, higher manufacturing efficiency, greater economies of scale, and enhanced equipment and process, the Company expects the overall total cost of polysilicon production for its Xinjiang facilities to decrease to approximately US$7.50 per kilogram.

Separately, the Company has launched a debottlenecking project to modernize some of its current Chemical Vapor Deposition (CVD) furnaces and upgrade other production equipment which will allow it to increase efficiency and production volume. The Company expects to complete the debottlenecking project and increase its annual capacity to 35,000 MT by the end of June, 2019.

The Company's Phase 4A capacity expansion project is currently under construction and is expected to begin pilot production in the fourth quarter of 2019. The Company expects to ramp up Phase 4A to full production in the first quarter of 2020 which will expand its total production capacity to 70,000 MT. When production from Phase 4A is fully ramped up, the Company's electricity rates will decrease further based on the agreement with the local electric utility, and the overall total cost of polysilicon production for its Xinjiang facilities is expected to decrease to approximately US$6.80 per kilogram.

Mr. Longgen Zhang, CEO of Daqo New Energy, commented, "I'd like to thank the entire team in our Xinjiang polysilicon production facilities for their hard work and dedication which enabled us to successfully complete the construction and installation of Phase 3B on schedule. Phase 3B will not only increase our capacity and reduce our costs, but also improve our product quality, allowing us to achieve production capability of approximately 80% mono-crystalline grade polysilicon, of which a half will be applicable for use in N-type mono-crystalline solar cells. We believe this demonstrates our long-term confidence in the solar PV industry, strong execution capabilities, and commitment to our customers. We eagerly look forward to the new era of grid parity in the global solar PV market and believe it has the potential to significantly change the way people produce and consume energy. We will continue to strengthen our leading position in the industry by expanding capacities, improving quality and reducing cost structure in order to meet the growing demand for our ultra-high-quality polysilicon."
