“We are pleased with our solid performance in the fourth quarter. We saw record shipment volumes, maintained our leading position as one of the largest solar companies in the world, and continued to increase our earnings quarter to quarter,” said Mr. Jifan Gao, Chairman and CEO of Trina Solar.

“We also made significant progress in our downstream business. We connected two utility scale solar power plants totaling 210 MW in Xinjiang and Jiangsu provinces, and both are generating electricity. Our project pipeline in China is expanding and we are growing our downstream business at a steady pace. Overseas, we closed the sale of a 13.2 MW project in the UK in December 2014. The cash generated by the sale of the project will provide additional capital for the expansion of our downstream businesses. We expect our growing portfolio of overseas projects in the UK and Japan that we expect to sell upon completion to further contribute to our downstream business expansion in 2015.

“In the second half of 2014, we strengthened our focuses on developing distributed generation (“DG”) projects in China. We have completed a number of projects and we will leverage our experience in developing utility scale projects and our module sales channels to further tap into the DG market and bolster our current downstream pipeline in China in 2015.

“In addition, we continued to deliver impressive new product innovations in solar cell technology. Our deep commitment to R&D and to delivering high quality products ensures our leading position in the very competitive and highly regulated PV industry. Our proven track record for superior quality, innovation, and efficient execution in the manufacturing sector positions us well as we build our company into a major developer and operator of solar projects.

“Overall, 2014 was a successful year for Trina Solar. Both our manufacturing and downstream businesses delivered strong results, and we emerged as the world’s largest supplier of solar modules. We took advantage of the rapidly growing demand in China, the world’s largest market for solar products, as well as the expansion of sales across various Asia-Pacific and Americas markets. We were also able to mitigate the industry trend of declining average sales prices (“ASPs”) without compromising product quality by re-engineering our manufacturing processes and supply chain to drive down costs and by growing our portfolio of downstream projects to increase profitability.

“In 2015, we believe that our focus on technological innovation and delivering the highest quality and diversified module portfolio will drive growth in an expanding market. We will continue to build world-class capabilities and align our global resources to reinforce our leading position in the module business while exploring the utility, DG and other downstream markets.”

Fourth Quarter 2014 Results

Net Revenues

Net revenues were $705.0 million, an increase of 14.3% sequentially and an increase of 34.1% year-over-year. Total shipments were 1,098.8 MW, consisting of 1,070.5 MW of external shipments and 28.3 MW of shipments to the Company’s downstream power projects. This compares with total shipments of 1,063.8 MW in the third quarter of 2014 and 770.1 MW in the fourth quarter of 2013. The sequential increase in revenues and shipments was primarily due to rising shipment volumes to China, Europe and the rest of Asia. The year-over-year increase in revenues and shipments was driven largely by growing demand from key geographical regions, particularly China, Japan and the U.S.

Gross Profit and Margin

Gross profit was $111.0 million, compared with $102.8 million in the third quarter of 2014 and $79.1 million in the fourth quarter of 2013.

Gross margin was 15.7%, compared with 16.7% in the third quarter of 2014 and 15.1% in the fourth quarter of 2013. The sequential decrease in gross margin was the result of several factors, including a change in the sales mix, reflecting higher shipments to China and other Asia-Pacific markets with relatively low ASPs, and fewer shipments to Japan in the quarter, which had relatively higher ASPs compared with other markets, coupled with a general decline in ASPs in some other key markets. The year-over-year margin increase was mainly due to the lower gross profit caused by the disposal and impairment loss on the Company’s downstream projects in the U.S. which was recognized in the fourth quarter of 2013.

Operating Expenses, Income and Margin

Operating expenses were $80.5 million, an increase of 19.9% sequentially and 35.7% year-over-year. The sequential increase was primarily due to an increase in salary, wages and benefits to employees. The Company’s operating expenses represented 11.4% of the fourth quarter net revenues, an increase from 10.9% in the third quarter of 2014 and 11.3% in the fourth quarter of 2013. Operating expenses included a reversal of accounts receivable provisions of 1.0 million in the fourth quarter of 2014, compared with $3.0 million in the third quarter of 2014 and $9.5 million in the fourth quarter of 2013. This provision reversal contributed to the increase in the operating expense ratio sequentially and year-over-year.

As a result, operating income was $30.5 million, compared with $35.6 million in the third quarter of 2014 and $19.8 million in the fourth quarter of 2013. Operating margin was 4.3%, compared with 5.8% in the third quarter of 2014 and 3.8% in the fourth quarter of 2013.

Net Interest Expense

Net interest expense was $8.3 million, compared with $7.0 million in the third quarter of 2014 and $8.2 million in the fourth quarter of 2013.

Foreign Currency Exchange Gain (Loss)

The Company recorded a net foreign currency exchange loss of $7.6 million, which included a gain on change in fair value of foreign exchange derivative instruments of $1.7 million. This compares with a net loss of $15.1 million in the third quarter of 2014 and a net gain of $1.8 million in the fourth quarter of 2013. The loss on foreign currency exchange was mainly due to the depreciation of the Euro and Japanese Yen against the U.S. dollar in the fourth quarter of 2014.

Income Tax Expense (Benefit)

Income tax expense was $1.7 million, compared with income tax expense of $5.2 million in the third quarter of 2014 and income tax benefit of $1.1 million in the fourth quarter of 2013.

Net Income (Loss) and Earnings (Loss) per ADS

Net income was $13.9 million, compared with $10.6 million in the third quarter of 2014 and $15.3 million in the fourth quarter of 2013. Net income excluding the net foreign exchange loss was $21.5 million, compared with $25.6 million in the third quarter of 2014.

Net margin was 2.0%, compared with 1.7% in the third quarter of 2014 and 2.9% in the fourth quarter of 2013. Net margin excluding net foreign exchange was 3.0% in the fourth quarter of 2014.

Earnings per fully diluted ADS were $0.13, compared with $0.14 in the third quarter of 2014 and $0.21 in the fourth quarter of 2013. Earnings per ADS excluding net foreign exchange loss, was $0.21 in the fourth quarter of 2014.

Financial Condition

As of December 31, 2014, the Company had $539.8 million in cash and cash equivalents, and restricted cash. Total bank borrowings were $842.7 million, of which $820.3 million were short-term borrowings, including $82.4 million of the current portion of long-term borrowings.

Shareholders’ equity was $972.8 million as of December 31, 2014, an increase from $930.9 million at the end of the third quarter of 2014.

Full Year 2014 Results

Total module shipments were 3.66 GW, consisting of 3.34 GW of external shipments and 324 MW of shipments to the Company’s downstream power projects, an increase of 41.9% from 2.58 GW in 2013, primarily driven by strong demand from China, Japan and the U.S.

Net revenues were $2.29 billion, an increase of 28.8% from $1.77 billion in 2013. Gross profit was $385.6 million, an increase of 76.7% from $218.2 million in 2013. Overall gross margin was 16.9%, compared with 12.3% in 2013. The gross margin expansion in 2014 was primarily due to faster reduction in manufacturing costs compared with the general decline in ASP and increased sales of downstream solar projects further improve gross margins. Operating profit was $120.1 million, compared with a loss of $38.1 million in 2013. Operating margin was 5.3%, compared with negative 2.1% in 2013.

Net income was $61.3 million, compared with a net loss of $72.2 million in 2013. Net margin was 2.7%, compared with negative 4.1% in 2013.

Earnings per fully-diluted ADS were $0.74, compared with a loss per fully diluted ADS of $1.01 for 2013.
