Third Quarter 2014 Financial Review

Total Revenue and Shipments

For the third quarter of 2014, total revenue was US$63.3 million, compared with US$88.5 million in the second quarter of 2014. The decrease in revenue was mainly due to a combination of lower total shipments and lower ASP in both cells and modules during the quarter. Revenue from the Company’s self-brand modules and cells business totaled US$60.2 million or 95.1% of the total revenue, while revenue from the modules and cells processed under OEM arrangements, was US$1.5 million, or for 2.4% of total revenue.

Total shipments for the third quarter of 2014 were 137.8MW, a decrease of 25.3% from 184.5MW in the previous quarter. The decrease in total shipment was primarily due to the lower shipments to France and India as compared with prior quarter. Total module shipments, including module processed under OEM arrangement of 5.4MW, were 76.2MW for the third quarter of 2014. Total cell shipments, including cell processed under OEM arrangements of 11.3MW, were 61.6MW for the third quarter of 2014.

Asia continued to be the largest market for the Company, accounting for 71.5% of total revenue in the third quarter of 2014, of which 50.6% of total revenue was generated from China market and 17.1% of total revenue was contributed by Japan. Sales to European markets represented 23.3% of total revenue in the third quarter of 2014, with France contributing 7.0% of total revenue.

ASP

ASP for the Company’s self-branded modules for the third quarter was US$0.63 per watt, as compared to US$0.66 per watt in the previous quarter. The decrease in module ASP was primarily due to higher shipments into low-price regions, including China. ASP for the Company's self-branded cells during the third quarter of 2014 was US$0.31 per watt, compared with $0.32 per watt in the previous quarter.

Wafer and Conversion Costs

Blended wafer costs in the third quarter of 2014 were US$0.24 per watt, unchanged from the previous quarter. Conversion costs of cells and modules manufactured in the third quarter of 2014 were US$0.16 and US$0.21 per watt, respectively, compared with US$0.14 and US$0.19 per watt, respectively, in the previous quarter. The two-cent increase in the Company’s conversion costs was primarily due to the lower shipments and capacity utilization for this quarter.

Gross Profit and Gross Margin

Gross losses for the third quarter were US$2.4 million on gross margin of negative 3.8%, compared to gross profit of US$5.5 million on gross margin of 6.2% for the second quarter of 2014. The decrease in gross profit and gross margin was due to a combination of the decrease in total revenue and the increase of cost of sales.

Operating Expenses, Operating Loss and Net Loss

Operating expenses decreased 35.2% to US$9.2 million in the third quarter of 2014, from US$14.2 million in the second quarter of 2014. The sequential decrease in operating expenses was primarily due to a US$4.7 million reduction in general and administration expenses. During the third quarter of 2014, general and administration expenses were US$5.7 million, the reduction of which was partially attributable to the reversal of bad debt provision of US$3.4 million, compared with a bad debt provision of US$3.2 million accrued in the previous quarter.

Loss from operations was US$11.6 million in the third quarter of 2014, compared with US$8.7 million in the second quarter of 2014. In addition, the Company had other expense of US$9.5 million, which was primarily due to the foreign exchange loss from the depreciation of Euro against RMB, while the Company generated other operating income of US$10.2 million during the second quarter of 2014 due to the disposal of one idle subsidiary of the Company.

Correspondingly, net loss attributable to ordinary shareholders was US$25.6 million in the third quarter of 2014, compared with US$5.7 million in the previous quarter.

Amount Due from/to Related Parties

Amount due from related parties totaled US$74.0 million as of September 30, 2014, a decrease of US$3.2 million compared to US$77.2 million as of June 30, 2014. Amount due to related parties totaled US$9.1 million as of September 30, 2014, an increase of US$0.5 million compared to US$8.6 million as of June 30, 2014.

Inventory

Inventories at the end of the third quarter of 2014 totaled US$69.6 million, an increase of US$13.7 million from US$55.9 at the end of June 30, 2014, which is mainly due to lower shipment during the quarter.
