Fourth Quarter 2013 Results

Net revenue for the fourth quarter of 2013 was $519.5 million, up 5.8% from $490.9 million in the third quarter of 2013 and up 76.2% from $294.8 million in the fourth quarter of 2012.  Total solar module shipments in the fourth quarter of 2013 were 621 MW, compared to 478 MW in the third quarter of 2013 and 404 MW in the fourth quarter of 2012.  Solar module shipments to the Chinese market represented 42.9% of total shipments in the fourth quarter of 2013, compared to less than 1% in the third quarter of 2013, and 9.9% in the fourth quarter of 2012.  Solar module shipments to the Japanese market represented 19.7% of total shipments in the fourth quarter of 2013, compared to 29.5% in the third quarter of 2013 and 11.7% in the fourth quarter of 2012.  Solar module shipments in the fourth quarter of 2013 included 41 MW used in the Company’s total solutions business, compared to 60 MW in the third quarter of 2013 and 16 MW in the fourth quarter of 2012.

By geography, in the fourth quarter of 2013, sales to the European markets represented 5.5% of net revenue, sales to the Americas represented 32.1% of net revenue, and sales to Asia and all other markets represented 62.4% of net revenue, compared to 9.5%, 46.9% and 43.6%, respectively, in the third quarter of 2013 and 40.6%, 20.0% and 39.4%, respectively, in the fourth quarter of 2012.

Gross profit in the fourth quarter of 2013 was $101.3 million, compared to $100.2 million in the third quarter of 2013 and $14.9 million in the fourth quarter of 2012.  The slight sequential increase in gross profit was primarily due to higher module shipments and a $14 million reduction in warranty cost to reflect the general decline in module prices, which more than off-set the lower contribution from the Company’s total solutions business in the fourth quarter of 2013. The year-over-year increase in gross profit was primarily due to the increase in revenue contribution from the Company’s higher margin total solutions business, as well as higher module shipments and lower module manufacturing cost, which was partially off-set by a slight decline in module average selling price.  Gross margin in the fourth quarter of 2013 was 19.5%, compared to 20.4% in the third quarter of 2013 and 5.0% in the fourth quarter of 2012.

Total operating expenses were $56.0 million in the fourth quarter of 2013, up 24.5% from $44.9 million in the third quarter of 2013 and down 47.4% from $106.4 million in the fourth quarter of 2012.

Selling expenses were $28.5 million in the fourth quarter of 2013, up 33.9% from $21.2 million in the third quarter of 2013 and 14.0% from $25.0 million in the fourth quarter of 2012.  The sequential quarterly increase in selling expenses was primarily due to higher shipping, salary and credit insurance expenses. The year-over-year increase in selling expenses was primarily due to higher salary and bonus as well as higher shipping, credit insurance and rental expenses, partially offset by lower marketing expenses.

General and administrative expenses were $24.3 million in the fourth quarter of 2013, up 17.1% from $20.7 million in the third quarter of 2013 and down 69.0% from $78.3 million in the fourth quarter of 2012.  The sequential increase in general and administrative expenses was primarily due to an asset impairment charge of $3.7 million related to the write-down of the Company’s mono-crystalline ingot furnaces, as well as increased salary expenses, partially off-set by a $2.2 million decrease in bad debt expenses.  The year-over-year decrease in general and administrative expenses was primarily due to provisions for bad debt and for an arbitration decision against the Company totaled approximately $61.2 million in the fourth quarter of 2012.

Research and development expenses were $3.2 million in the fourth quarter of 2013, compared to $3.0 million in the third quarter of 2013 and $3.1 million in the fourth quarter of 2012.

Operating margin was 8.7% in the fourth quarter of 2013, compared to 11.3% in the third quarter of 2013 and negative 31.0% in the fourth quarter of 2012.  The sequential decline in operating margin was primarily due to the higher selling expenses, decline in gross margin as well as the asset impairment charge in the fourth quarter of 2013.  The year-over-year increase in operating margin was primarily due to higher gross margin and lower operating expenses in the fourth quarter of 2013 compared to the same period in 2012.

Interest expense in the fourth quarter of 2013 was $9.9 million, compared to $11.8 million in the third quarter of 2013 and $9.9 million in the fourth quarter of 2012.  The sequential decrease in interest expense was primarily due to lower bank charges in the fourth quarter of 2013.

Interest income in the fourth quarter of 2013 was $2.8 million, compared to $2.7 million in the third quarter of 2013 and $3.7 million in the fourth quarter of 2012.

The Company recorded a gain on change in fair value of derivatives of $8.9 million in the fourth quarter of 2013, compared to a loss of $1.6 million in the third quarter of 2013 and a gain of $2.3 million in the fourth quarter of 2012.  Net foreign exchange loss in the fourth quarter of 2013 was $18.5 million compared to a net foreign exchange gain of $2.3 million in the third quarter of 2013 and a net foreign exchange loss of $10.8 million in the fourth quarter of 2012.

Income tax expense in the fourth quarter of 2013 was $3.7million, compared to income tax expense of $12.4 million in the third quarter of 2013 and income tax benefit of $3.3 million in the fourth quarter of 2012.

Net income attributable to Canadian Solar in the fourth quarter of 2013 was $20.9 million, or $0.39 per diluted share, compared to net income of $27.7 million, or $0.56 per diluted share, in the third quarter of 2013, and net loss of $105.0 million, or $2.43 per diluted share, in the fourth quarter of 2012.

Management’s expectations in respect to profitability in the fourth quarter and the fiscal year 2013 are subject to the final ruling by the Suzhou Intermediate Court on a contract dispute between Canadian Solar and LDK as previously disclosed. If the court was to rule against Canadian Solar and order the Company to pay the award to LDK, before the company files its Annual Report on Form 20-F in April of 2014, Canadian Solar may have to make a provision for the fourth quarter of 2013 and the full year of 2013, which would impact the Company’s profitability.

Financial Condition

As of December 31, 2013, the Company had $679.4 million of cash, cash equivalents and restricted cash, compared to $681.7million as of September 30, 2013.

On February 18, 2014, the Company closed a concurrent offering of 3,194,700 common shares and US$150 million in aggregate principal amount of 4.25% convertible senior notes due 2019 and received aggregate net proceeds of approximately US$255.7 million after deducting discounts and commissions but before offering expenses.

Accounts receivable, net of allowance for doubtful accounts, at the end of the fourth quarter of 2013 were $280.7 million, compared to $271.8 million at the end of the third quarter of 2013.  Accounts receivable turnover was 59 days in the fourth quarter of 2013, compared to 62 days in the third quarter of 2013.

Inventories at the end of the fourth quarter of 2013 were $231.2 million, compared to $220.6 million at the end of the third quarter of 2013.  Inventory turnover was 53 days in the fourth quarter of 2013, compared to 55 days in the third quarter of 2013.

Accounts and notes payable at the end of the fourth quarter of 2013 were $639.4 million, compared to $589.7 million at the end of the third quarter of 2013.

Dr. Shawn Qu, Chairman and Chief Executive Officer of Canadian Solar, remarked: “We are very pleased to have achieved our goal to return the Company to profitability in 2013, underscoring the successful execution of our strategy of expanding our higher margin total solutions business, and seeking profitable growth in our module business, rather than simply competing on MW volume and price.  We continue to capitalize on our high-visibility contracted late-stage solar project pipeline, which increased to 1.3 GW DC, even after completing construction of over 200 MW in 2013.  Reflecting our geographic diversity, our late-stage solar project pipeline, including those projects currently in construction comprises approximately 477 MW DC in Canada, 329 MW DC in Japan, 164 MW DC in the U.S. and 290 MW DC in China.   We also have confidence in the ongoing development of our early to mid-state project pipeline, which now exceeds 3.2 GW DC, and we hope many of these opportunities will be converted into real projects in the next 2-3 years.  Finally, while our growth in 2013 was led by our total solutions business, we had a positive contribution from our solar module business due to global capacity rationalization, stable average selling prices and robust demand across many key geographies.”

Michael G. Potter, Senior Vice President and Chief Financial Officer of Canadian Solar, commented: “We achieved a 19.5% gross margin in the fourth quarter of 2013, exceeding our previously upwardly revised guidance of 16% to 18%, with total solar module shipments of 621 MW.  We remain focused on driving profitable growth, while prudently investing in support of our solar project pipeline growth.  We exited the fourth quarter of 2013 with one of the industry’s strongest and most flexible balance sheets.  We have taken advantage of the favorable financing environment to raise funds and lay the foundation for future sustained, long-term profitable growth. Our strong cash position helps us to fund the development of our existing project pipeline and to take advantage of numerous other actionable project opportunities.”

Utility Scale Project Pipeline Update

At the end of January of 2014, the Company had a pipeline of late stage utility-scale solar projects totaling approximately 1.3 GW DC.  These projects include owned and joint-venture projects as well as projects where we provide engineering, procurement and construction (EPC) services.

In Canada, during the fourth quarter of 2013, the Company closed the sale of the Mississippi Mills project in Ontario, Canada to TransCanada for over C$61.0 million.  In addition, one project, William Rutley is in commercial operation pending completion of the sale to an investor.  The Company’s late stage solar project pipeline in Ontario, Canada, including those in construction now stands at, approximately 477 MW DC, including owned projects and EPC service contracts, which combined represent a revenue opportunity of over C$1.7 billion once the projects are built and connected to the grid.

The following table summarizes the status of the Company’s Ontario, Canada solar projects:

(1) Commercial Operation Date.

In Japan, at the end of January of 2014, the Company’s late stage, utility-scale solar power project pipeline reached 329 MW DC.  The Company expects to begin construction of its first Japanese solar power project in the first half of 2014.

The following table summarizes the status of the Company’s solar project pipeline in Japan:

In the United States, during the fourth quarter of 2013, the Company completed construction of three solar power plants totaling approximately 24 MW DC.   At the end of the fourth quarter of 2013, the Company’s utility-scale project pipeline totals approximately 164 MW DC.

The following table represents the status of the Company’s United States solar project pipeline:

In China, the Company built and connected to the grid a 30 MW DC solar power plant in the western part of China and a 10MW DC project in the Jiangsu Province. Exiting 2013 the Company has identified a pipeline of late stage utility -scale projects in China totaling 290 MW, as follows:

Business Outlook

The Company’s business outlook is based on management’s current views and estimates with respect to operating and market conditions, its current order book, global and local financing environment as well as uncertainty relating to customer final demand and solar project construction schedule.  Management’s views and estimates are subject to change without notice.

For the first quarter of 2014, the Company expects module shipments to be in the range of approximately 470 MW to 490 MW.  Total revenue for the first quarter of 2014 is expected to be in the range of $415 million to $430 million, with gross margin expected to be between 14% and 16%.

Management continues to see strong demand for the Company’s products in the first quarter of 2014, as the seasonality in Chinese market was more than compensated by the increase in demand from Japan and the U.S. However, longer shipping time to these markets will push some revenue to the second quarter of 2014. In addition, the production output from the Company’s module factories in China was low during the Chinese New Year holiday period.

Meanwhile, the Company’s revenue and gross margin in the first quarter of 2014 are expected to be adversely affected by the severe winter conditions in North America, which delayed construction and recognition of approximately $100.0 million in revenue from some of its utility-scale projects in Canada.  The Company expects to recognize this revenue in the second and third quarter of 2014. The expected gross margin in the first quarter of 2014 is adversely impacted by approximately 100 basis points (1.0%) due to the recently reported fire incident at the Company’s cell plant in Suzhou. The Company expects to fully recover its losses from its property and business interruption insurance in later quarters.

For the full year 2014, the Company expects annual module shipments to be in the range of 2.5 GW to 2.7 GW, including 400 MW to 500 MW of project recognition.  In addition, the Company expects to build and hold up to 250MW of project assets during 2014.  The Company expects that its net revenue for 2014 will be in the range of approximately $2.7 billion to $2.9 billion, with approximately 50% of revenue being derived from its total solutions business.

The Company’s Canadian and U.S. project revenue recognition is expected to be back-end loaded in 2014 due to permitting and construction schedule as well as US GAAP accounting rules which, for most Canadian projects, only allow revenue recognition after commercial operation date (COD) and the transfer of ownership to end customers. The estimated COD of all of the Company’s late-stage projects is disclosed in this press release to provide better granularity to investors.

Dr. Shawn Qu, Chairman and Chief Executive Officer of Canadian Solar, remarked: “We are excited about our outlook for 2014, given the size of our existing project pipeline, the expected growth in the broader solar market and the industry’s continued capacity rationalization.   We expect China, Japan, Canada, the U.S. and India to remain healthy markets for us through 2014.  We are incrementally more positive on China because of its market size and improved payment terms and pricing.  In addition, we see more opportunities in South Africa, the Middle East, and South America.  Customers and investors want to partner with us because we are one of the largest and most successful companies in the solar space, with a strong balance sheet, a proven track record of execution, and offering integrated total solar solutions.”
