D. Risk Factors

Risks Relating to Our Business

Our futureability to return to growth and profitability depend on the demand for photovoltaic products and the development of photovoltaic technologies.technologies, among other things.

The solar industry is at a relatively early stage of development, and the extent of acceptance of photovoltaic products is uncertain. The photovoltaic industry does not have data as far back as the semiconductor industry or other more established industries, for which trends can be assessed more reliably from data gathered over a longer period of time. Demand for photovoltaic products may not develop or may develop to a lesser extent than we anticipate. Many factors may affect the viability of widespread adoption of photovoltaic technology and demand for photovoltaic products, including:

In the event that demand for solar products does not expand as we expect or photovoltaic technologies do not develop in a manner that increases the demand for polysilicon, ASPs may continue to fall and our future growth and profitability will be materially and adversely affected.

Global supply for polysilicon has exceeded and may continue to exceed demand, which could cause polysilicon prices to continue to decline and materially and adversely affect our profitability.

Our polysilicon sales prices are affected by a variety of factors, including global supply and demand conditions. Over the years, many polysilicon manufacturers have significantly increased their capacity to meet customer demand and continue to expand capacities in order to achieve economies of scale. However, the globalslow and uneven economic slowdown, the crisis inrecovery from the global financial markets andcrisis as well as the significant decrease in global petroleum prices since their peak in mid-2008 have reduced or delayed the general demand for photovoltaic products. If the demand continues to decline or if our customers delay their orders, we may not be able to sell our polysilicon at desirable prices, or at all. In late 2008 and 2009, newly available polysilicon supply and slowed global photovoltaic market growth resulted in an excess supply of polysilicon, which led to a significant decline in polysilicon prices. The decliningglobal photovoltaic demand recovered substantially from the second half of 2010 through the first half of 2011. Nevertheless, market price for polysilicon prices had a negative impact on our revenues in 2009.experienced another significant decline since the second half of 2011 due to excess supply and decreasing demand. In 2012, the market price for polysilicon continued to decline. As a result of the significant decline of market price for polysilicon supply and demand fluctuation, we had to significantly lowerreduced the selling price of our polysilicon and thus experienced continued decrease in 2009. The global photovoltaic demand increased substantiallyrevenues derived from polysilicon in the second half of 2010 and, as a result, the demand for polysilicon increased as well. Consequently, polysilicon prices ceased to decline in the middle of 2010 and rose mildly in the second half of 2010.2012. If we experience further decline in demand in the future or if prices decrease and we are unable to lower our costs in line with the average selling price decline, our operating margins will continue to be reduced and our financial condition and results of operations may be further materially and adversely affected.

Our limited operating history may not serve as an adequate basis to judge our future prospects and results of operations.

We have a limited operating history. We commenced polysilicon manufacturing in July 2008. Several of our senior management and key employees have worked together at our company for only a relatively short period of time. Our future success will depend on our ability to expand our manufacturing capacity significantly beyond its current level and further expand our customer base. To address these risks, we must, among other things, continue to respond to competition and volatile market developments, attract, retain and motivate qualified personnel, implement and successfully execute expansion plans and improve our technologies. We cannot assure you that we will be successful in addressing such risks.

Although we were profitable in 2009 and 2010, we cannot assure you that our results of operations will not be adversely affected in the future. Our limited operating history makes the prediction of future results of operations difficult, and therefore, past results of operations achieved by us should not be taken as indicative of the rate of growth, if any, that can be expected in the future. Our business model, technology and ability to achieve satisfactory manufacturing yields for polysilicon at higher volumes are unproven. Compared to companies with a long and well-established operating history and companies operating in less volatile sectors, our results of operations are more susceptible to the impact of adverse operating environment and supply and demand risks.

Our revenues and results of operations have fluctuated and are likely to fluctuate in the future.

Fluctuations of our revenues and results of operations may occur on a quarterly and on an annual basis and may be due to a number of factors, many of which are beyond our control. These factors include, among others, fluctuation in the global average selling prices of photovoltaic products, fluctuation in the volume of our products shipped, changes in end-user demand for the photovoltaic products manufactured and sold by us or our customers, the gain or loss of significant customers, the availability of governmental subsidies or financial support and changes in prices of our electricity, raw material or labor costs. For example, our profits may decline in the upcoming quarters if one or more of these factors occur. Furthermore, wafers, cells and modules traditionally had lower profit margins than polysilicon and we may need to price aggressively to gain market share or remain competitive in these new businesses, which may further reduce our profit margins and cause our financial results to fluctuate from time to time.

Therefore, you should consider our future prospects in light of the risks and uncertainties experienced by early stage companies in a rapidly evolving and increasingly competitive market in China.

Alternative technologies in cell manufacturing may reduce the demand for polysilicon.

The vast majority of silicon-based photovoltaic cell manufacturers use chunk or granular polysilicon. However, alternative technologies have been commercialized. One such technology, thin-film cell production, uses little to no silicon in the production of solar cells. Thin-film solar cells are currently less costly to produce than silicon-based solar cells. Significant expansion of thin-film solar cell production has been announced which may put pressure on the entire value chain of silicon-based solar cell production. This expansion may in turn restrict the market for silicon-based solar cells, which would reduce the demand for our polysilicon. If the demand for polysilicon is adversely affected by increased demand for, and improvements to, alternative technologies, our revenues and results of operations could be materially and adversely affected.

Our future success depends substantially on our ability to significantly expand our polysilicon production capacity and output, which exposes us to a number of risks and uncertainties.

Our future success depends on our ability to significantly increase both polysilicon production capacity and output. If we fail to do so, we may not be able to benefit from economies of scale to reduce our costs per kilogram of polysilicon, to meet our obligations under supply agreements, to maintain our competitive position or to improve our profitability. Our ability to establish additional production capacity and increase output is subject to significant risks and uncertainties, including:

We plan to expand downstream to become a vertically integrated photovoltaic manufacturer and we may not be successful in this new endeavor, which could adversely affect our results of operations and financial condition.

We plan to become a vertically integrated photovoltaic manufacturer by entering into the wafer manufacturing business, ramping up our module manufacturing business and potentially entering into the cell manufacturing business in the future. Our ability to successfully implement our expansion strategy is subject to various risks and uncertainties, including:

If we are unable to manage these risks and successfully implement our expansion plans, our future results of operations may be material and adversely affected.

The reduction in or elimination of government subsidies and economic incentives for solar energy applications could cause demand for our products and our revenues to decline.

When upfront system costs are factored into cost per kilowatt hour, the current cost of solar power substantially exceeds the cost of traditional forms of energy in many locations. As a result, national and local governmental authorities in many countries, including China, have provided subsidies and economic incentives in the form of feed-in tariffs, rebates, tax credits and other incentives to distributors, system integrators and manufacturers of photovoltaic products to promote the use of solar energy and to reduce dependency on other forms of energy. We believe that the near-term growth of the market for solar energy applications depends in large part on the availability and size of government subsidies and economic incentives. The reduction or elimination of government subsidies and economic incentives may hinder the growth of this market or result in increased price competition for solar energy products, which could cause our revenues to decline. These government subsidies and economic incentives could be reduced or eliminated altogether. For example, in 2008, Spain set a cap of 500 megawatts for feed-in tariffs for solar power in 2009, and, in 2010, Spain announced its plan to cut the subsidized electricity prices paid to new photovoltaic solar power plants by up to 45%, both of which are expected to significantly reducereduced installations of new solar energy projects in the country. In 2009,2010, Germany introduced an approximately 24% to 26% solar feed-in tariffs reduction for rooftop systems and 20% to 25% reduction for ground-based systems. In early 2012, Germany further reduced its feed-in tariffs by 15% to up to 24.43 Euro cents per kilowatt hour for rooftop systems and up to 18.76 Euro cents per kilowatt hour for ground-based systems. In April 2012, Italian officials revealed the details of its latest renewable energy law. Amongst the proposals expected to become effective with the new law are cuts to Italy’s feed-in tariff, an annual installation cap, and a requirement to put all installations over 5MW through a competitive bidding process. In 2013, the German government reducedstill plans to cut the expansion of solar feed-in tariffspower after Germany added 7,500 megawatts and 7,600 megawatts of capacity in 2011 and 2012, respectively, to bring its total to 32,600 MW, which is nearly as much as the rest of the world combined. The German government wants to see the FIT cut by 9%. In July 2010, Germany implementedup to 30 percent in a further reductionone-off move, after a series of annual cuts of about 15 percent in solar feed-in tariffs of 16% for rooftop systems, 15% for farmland and 11% for spaces such as former military or industrial sites.recent years. Such actions may result in a significant fall in the demand for photovoltaic products. In

addition, government financial support of photovoltaic products has been, and may continue to be, challenged as being unconstitutional or otherwiseon constitutional grounds and found unlawful in certain other countries. The escalation of the European sovereign debt crisis since 2011 and the slowdown of the Chinese economy in 2012 may continue to exert downward pressure on the amount of government subsidiaries for solar energy applications in these two regions. Reductions in, or elimination of, government subsidies and economic incentives for solar energy applications before the photovoltaic industry reaches the economies of scale necessary for solar power to become cost-effective in a non-subsidized market place could result in decreased demand for solar generation products and, as a result, for polysilicon, which could cause our revenues to decline.

Our limited operating history may not serve as an adequate basis to judge our future prospects and results of operations.

We have a limited operating history. We commenced polysilicon manufacturing in 2008. Several of our senior management and key employees have worked together at our company for only a relatively short period of time, and a number of our senior officers were recently promoted to their posts in October 2012. Our future success will depend on our ability to expand our manufacturing capacity significantly beyond its current level and further expand our customer base. To address these risks, we must, among other things, continue to respond to competition and volatile market developments, attract, retain and motivate qualified personnel, implement and successfully execute expansion plans and improve our technologies. We cannot assure you that we will be successful in addressing such risks.

Although we were profitable in 2010 and 2011, we experienced significant decrease in revenue and incurred substantial net loss in 2012. Our limited operating history makes the prediction of future results of operations difficult, and therefore, it is unclear if we could regain positive revenue growth or become profitable again in the future. Our business model, technology and ability to achieve satisfactory manufacturing yields for polysilicon at higher volumes are unproven. Compared to companies with a long and well-established operating history and companies operating in less volatile sectors, our results of operations are more susceptible to the impact of adverse operating environment and supply and demand risks.

Our revenues and results of operations have fluctuated and are likely to fluctuate in the future.

Fluctuations of our revenues and results of operations may occur on a quarterly and on an annual basis and may be due to a number of factors, many of which are beyond our control. These factors include, among others, fluctuation in the global average selling prices of photovoltaic products, fluctuation in the volume of our products shipped, changes in end-user demand for the photovoltaic products manufactured and sold by us or our customers, the gain or loss of significant customers, the availability of governmental subsidies or financial support and changes in our electricity, natural gas, raw material or labor costs. For example, our net loss may worsen in the upcoming quarters if one or more of these factors become unfavorable to our business. Furthermore, wafers traditionally had lower profit margins than polysilicon, and we may need to price aggressively to gain market share or remain competitive in this business, which may further reduce our net margins and cause our financial results to fluctuate from time to time.

Therefore, you should consider our future prospects in light of the risks and uncertainties experienced by early stage companies in a rapidly evolving and increasingly competitive market in China.

We experienced a significant decrease in our revenues and incurred a substantial net loss in 2012.

As a result of the slump in the global demand for and sales price of polysilicon, we experienced a significant decrease in our revenues for our continuing operations in 2012 and suffered a large net loss for the year. Compared with our revenues from continuing operations in 2011, our revenues from continuing operations in 2012 decreased by 62.6%, and we incurred a net loss of $115.6 million. While the global demand and sales price of polysilicon have been recovering in the first quarter of 2013 from their historical lows in 2012, we cannot predict when we will be able to regain a positive net income. If we cannot obtain positive revenue growth and regain profitability in the near future, our status as a going concern will be jeopardized.

We are facing significant working capital pressure in the current challenging market environment. Our major shareholders have committed to provide financial support to us to meet our working capital requirements and obligations as they come due. If the market continues to deteriorate and we are not able to obtain adequate financial support from our major shareholders or from other sources, we will face the risk of not being able to continue as a going concern.

The current challenging solar photovoltaic market situation results in low prices through the whole value chain, which caused our polysilicon and wafer businesses to experience significant financial losses. As of December 31, 2012, we had a working capital deficit (being our total consolidated current liabilities less our total consolidated current assets) of $163.8 million. If the market continues to be weak, we will continue to face significant pressure on our working capital. In addition, we committed significant capital expenditures on the equipment improvement projects in Wanzhou, Chongqing.

Nevertheless, our major shareholders with sufficient capital and liquidity agreed to provide the necessary financial support to us, as may be required, through Daqo Group Co., Ltd., or Daqo Group, an affiliated company of ours. In addition, we had committed and available bank standby credit facilities of $36.9 million, as of December 31, 2012. In sum, our continuation as a going concern is dependent upon continued financial support from our shareholders and our ability to continue to obtain other sources of financing.

Our consolidated financial statements do not reflect any adjustments relating to recoverability and classification of recorded assets or the amounts and classification of liabilities or any other adjustments that might be necessary should we be unable to continue as a going concern. Our inability to continue as a going concern would materially and adversely affect our financial condition, results of operations and business prospects.

We need a significant amount of cash to fund our future capital expenditure requirements and working capital needs; if we cannot obtain additional sources of liquidity when needed, our growth prospects and future profitability may be materially and adversely affected.

We need a significant amount of cash to fund our operations. In particular, we will need substantial additional funding to finance our technology improvement projects and potential expansion for polysilicon, to meet our working capital requirements, and to repay any short-term or long-term bank borrowings when due. We will also need cash resources to fund our research and development activities in order to remain competitive on cost and technology. We also need to contribute registered capital to our Chongqing and Xinjiang facilities in the amount of $26.4 million and $61.6 million respectively.

In the past, we relied in part on long-term bank borrowings and advance payments from customers to finance our working capital requirements. However, we expect that we may not be able to obtain a substantial amount of, or any, advance payments from customers in the future as the photovoltaic markets become increasingly competitive. Recently, payment collection in the solar photovoltaic industry has become increasingly challenging. Any delay or failure in collecting amounts owed from customers will adversely affect the Company’s cash flow situation. In addition, future acquisitions, expansions, market changes or other developments may cause us to require additional financing. We expect to incur additional debt in the future. Our ability to obtain external financing in the future is subject to a number of uncertainties, including:

If we are unable to obtain funding in a timely manner or on commercially acceptable terms, or at all, our growth prospects and ability to return to profitability may be materially and adversely affected.

We may not be successful in our efforts to continue to manufacture polysilicon in a cost-effective manner.

The technology used to manufacture polysilicon is complex, requires costly equipment and is continuously being modified in an effort to improve yields and product performance. We may face significant challenges relating to polysilicon production in the future. Microscopic impurities such as dust and other contaminants, difficulties in the manufacturing process, disruptions in the supply of utilities or defects in the key materials or tools used to manufacture polysilicon could interrupt manufacturing, reduce yields or cause a portion of the polysilicon to be rejected by our customers, which would materially and adversely affect our profitability.

Our effective capacity and ability to produce high volumes of polysilicon depend on the cycle time for each batch of polysilicon. We may encounter problems in our manufacturing process or facilities as a result of, among other things, production failures, construction delays, human error, equipment malfunction or process contamination, all of which could seriously harm our operations. We may experience production delays if any modifications we make in the manufacturing process to shorten production cycles are unsuccessful. Moreover, failure to achieve acceptable manufacturing levels may make our polysilicon costs uncompetitive, which could materially and adversely affect our business, financial condition and results of operations.

Further development in alternative polysilicon production technologies or other changes in the photovoltaic industry could render our production process too costly or obsolete, which could reduce our market share and cause our sales and profits to decline.

Although the vast majority of the polysilicon produced in the world utilizes the chemical vapor deposition process, or the “modified Siemens process,” several alternative production processes have been developed that may have significantly lower production costs. Compared with other polysilicon production processes, a disadvantage of the modified Siemens process is the large amount of electricity required. For example, MEMC and REC currently operate or are constructing facilities that use the “fluidized bed reactor” method for producing polysilicon. Tokuyama has developed a polysilicon technology called the “vapor-to-liquid deposition” process. Other polysilicon manufacturers are establishing facilities using upgraded metallurgical grade silicon process to produce solar-grade polysilicon. Moreover, some polysilicon manufacturers who are using “modified Siemens process” have adopted newer technologies such as Hydrochlorination, which could enable them to produce polysilicon in a more cost effective way comparing to the traditional “modified Siemens process. ”

Further developments in competing polysilicon production technologies may result in lower manufacturing costs or higher product performance than those achieved from the modified Siemens process, including the one we employ. We will need to invest significant financial resources in research and development to expand our market position, keep pace with technological advances in polysilicon production and effectively compete in the future. Failure to further refine our technology could make our production process too costly or obsolete, which could reduce our margins and market share, cause our revenues to decline and materially and adversely affect our results of operations.

Alternative technologies in cell manufacturing may reduce the demand for polysilicon.

The vast majority of silicon-based photovoltaic cell manufacturers use chunk or granular polysilicon. However, alternative technologies have been commercialized. One such technology, thin-film cell production, uses little to no silicon in the production of solar cells. Thin-film solar cells are currently less costly to produce than silicon-based solar cells. Significant expansion of thin-film solar cell production has been announced which may put pressure on the entire value chain of silicon-based solar cell production. This expansion may in turn restrict the market for silicon-based solar cells, which would reduce the demand for our polysilicon. If the demand for polysilicon is adversely affected by increased demand for, and improvements to, alternative technologies, our revenues and results of operations could be materially and adversely affected.

Our future success depends substantially on our ability to significantly expand our polysilicon production capacity and output, which exposes us to a number of risks and uncertainties.

Our future success depends on our ability to significantly increase both polysilicon production capacity and output. If we fail to do so, we may not be able to benefit from economies of scale to reduce our costs per kilogram of polysilicon, to meet our obligations under supply agreements, to maintain our competitive position or to improve our profitability. Our ability to establish additional production capacity and increase output is subject to significant risks and uncertainties, including:

Our future commercial production in Xinjiang, China may not be successful.

We finished construction of our Phase 2 polysilicon facilities in Shihezi, Xinjiang Uyghur Autonomous Region in September 2012 and have successfully reached our targets in terms of capacity and cost structure by the end of March 2013. Although the Xinjiang location provides many strategic advantages, including lower electricity costs, we face a number of uncertainties in relation with our future commercial production in Xinjiang.

There are many risks associated with our future production in Xinjiang, any of which could cause significant disruption to production, including:

One or more of these factors could harm our Xinjiang operations and consequently, could adversely affect our overall operating results.

We operate in an increasingly competitive market, and we may not be able to compete successfully with competitors who have greater resources than us.

The photovoltaic market is expected to become increasingly competitive. Our competitors include international polysilicon and wafer manufacturers, such as Hemlock, Wacker, OCI, REC, MEMC, M.Setek, Green Energy Technology and Sino-American Silicon and Chinese domestic polysilicon and wafer manufacturers, such as GCL-Poly, China Silicon Corporation, Sichuan Xinguang Silicon Science and Technology, LDK Solar, ReneSola, JinkoSolar and Comtec Solar Systems. In addition, many solar cell and module manufacturers, including some of our existing and potential customers, have established or have announced the intention of establishing polysilicon production or affiliate relationships with manufacturers of polysilicon. We compete with these in-house capabilities, which could limit our ability to expand our sales or even reduce our sales to our existing customers. As we execute our vertical integration strategy, we expect to face competition from local and international manufacturers, such as SunPower, Suntech Power, Solarfun and Canadian Solar and integrated photovoltaic product manufacturers such as Yingli Green Energy, SolarWorld, and Trina Solar. Many of our competitors have substantially greater financial, technical, manufacturing and other resources than we do. Our competitors’ greater size and longer operating history provide them with a competitive advantage with respect to manufacturing costs because of their economies of scale and their ability to purchase raw materials at lower prices. In addition, before we fully ramp up our wafer and module manufacturing facilities, the production cost of our wafers and modules will not be competitive to those of our competitors due to our relatively small production scale. Our competitors may have stronger relationships or may enter into exclusive relationships with some of our key customers. As a result, they may be able to respond more quickly to changing customer demands or to devote greater resources to the development, promotion and sales of polysilicon than we can. Failure to adapt to changing market conditions and to compete successfully with existing or new competitors may materially and adversely affect our financial condition and results of operations.

We depend on a limited number of customers and sales contracts for a significant portion of our revenues, and the loss of any customer or cancellation of any contract may cause significant fluctuations or declines in our revenues.

In 20092010, 2011 and 2010,2012, our top three customers in aggregate accounted for approximately 53.6%35.1%, 35.2% and 29.1%40.9% of our total revenues, respectively. We anticipate that our dependence on a limited number of customers will continue for the foreseeable future. Consequently, any one of the following events may cause material fluctuations or declines in our revenues:

If we are unable to manage our growth effectively, our business and financial results may be adversely affected.

We have experienced a period of rapid growth and expansion, despite the significant set-back in 2012, that has placed, and continues to place, significant strain on our management and resources. To accommodate our growth, we anticipate that we will need to implement a variety of new and upgraded operational and financial systems, procedures and controls, including the improvement of our accounting and other internal management systems, all of which require substantial management efforts. We also will need to continue to expand, train, manage and motivate our workforce and manage our customer relationships. All of these endeavors will require substantial management efforts and skills and require significant additional expenditures. We cannot assure you that we will be able to manage our growth effectively, and any failure to do so may have a material adverse effect on our business and financial results. Moreover, even if we do expand our polysilicon manufacturing capacity and our wafer and module businessesbusiness as planned, we may be unable to generate sufficient customer demand for our photovoltaic products to support our increased production levels or successfully integrate our polysilicon wafer and modulewafer manufacturing businesses to achieve operational efficiency, which could adversely affect our business and results of operations.

We expect to experience increased costs as a result of the construction of our Phase 2 facilities. See “Item 4. Information on the Company—B. Business Overview—Manufacturing Capacity.” Before our production facilities become fully operational, we will need to make substantial payments for the installation of machinery and equipment, the training of personnel and other related expenses. A significant portion of these payments will be made prior to any revenues being realized from the expansion project. If we cannot complete our expansion plans on a timely basis or increase production yields in our facilities in accordance with our plan, we may not be able to achieve lower costs per unit of production, which would decrease our margins and lower our profitability.

Polysilicon production is energy-intensive, and if our energy costs rise or if our electricity and other utility supplies are disrupted, our results of operations will be materially and adversely affected.

The polysilicon production process, particularly the modified Siemens process that we use, is highly dependent on a constant supply of electricity and other utilities, such as steam, natural gas and water, to maintain the optimal conditions for polysilicon production. If electricity or other utility supplies are not maintained at the desired level, we may experience significant delays in the production of polysilicon. In the past, there were shortages in electricity supply in various regions across China, especially during peak seasons, such as in the summer. In addition, the uncommon cold weather in China in the winter of 20092010 resulted in a surging natural gas demand, which in turn caused severe gas shortage in many regions, including Chongqing, where substantially allone of our polysilicon manufacturing facilities aresites is located. The local governmental authorities in the worst-hit areas took measures to reduce or restrict the amount of natural gas supplied to non-residential users. We primarily use natural gas for our in-house steam production and steam is critical for our manufacturing process. Although the natural gas shortage did not directly affect our operations, if the shortage becomes more severe in the future, our natural gas supply may be reduced or suspended, which would significantly disrupt our manufacturing process. In addition to shortages, we are subject to potential risks of interruptions in energy supply due to power outage, equipment failure, weather conditions or other causes which could force us to cease production for a prolonged period of time. In the event that electricity or other utility supplies to our manufacturing facilities are disrupted, our business, results of operations and financial condition could be materially and adversely affected.

Even if we have access to sufficient sources of electricity and other utilities, any significant increase in the costs of utilities could adversely affect our profitability, as we consume substantial amounts of electricity and other utilities in our manufacturing process. If electricity and other utility costs were to rise, our results of operations could be materially and adversely affected.

The full implementation of the closed loop system by other polysilicon manufacturers has diminished and may continue to diminish our competitive advantages provided by this system.

We have implemented the modified Siemens process in a completely closed loop system. We believe we are one of the few China-based polysilicon manufacturers that have fully implemented the closed loop system in the polysilicon production process. Compared to the open loop system, the closed loop system uses raw materials more efficiently, requires less electricity and produces less pollution. Although the closed loop system has lower manufacturing costs than the open loop system, manufacturing facilities based on the open loop system can be built within a shorter period time with less initial capital investment for equipment. Most of polysilicon manufacturing facilities in China were traditionally built based on the open loop system. However, as the polysilicon market may face downward pricing pressure from time to time, we believe that an increasing number of China-based manufacturers are converting their open loop system to the closed loop system and some of them have completed such conversion. The full implementation of the closed loop system by other polysilicon manufacturers has diminished and may continue to diminish our competitive advantages provided by this system.

We need a significant amount of cash to fund our future capital expenditure requirements and working capital needs; if we cannot obtain additional sources of liquidity when needed, our growth prospects and future profitability may be materially and adversely affected.

We need a significant amount of cash to fund our operations. In particular, we will need substantial additional funding to finance our expansion of polysilicon and module production capacities, our establishment of wafer business and our working capital requirements and to repay any short-term or long-term bank borrowings when due. We will also need cash resources to fund our research and development activities in order to remain competitive on cost and technology. In the past, we relied in part on long-term bank borrowings and advance payments from customers to finance our working capital requirements. However, we expect that we may not be able to obtain a substantial amount of, or any, advance payments from customers in the future as the photovoltaic markets become increasingly competitive. In addition, future acquisitions, expansions, market changes or other developments may cause us to require additional financing. We expect to incur additional debt in the future. Our ability to obtain external financing in the future is subject to a number of uncertainties, including:

If we are unable to obtain funding in a timely manner or on commercially acceptable terms, or at all, our growth prospects and future profitability may be materially and adversely affected.

Our current indebtedness could adversely affect our business, financial condition and results of operations.

As of December 31, 2010,2012, we had outstanding borrowings of $154$307.8 million with a weighted average floating interest rate of 5.86%6.92%, and we expect to incur additional debt in the future. We borrowed the majority of these bank loans from Bank of China and China Construction Bank Wanzhou Branch with guarantees from Daqo Group, an affiliated company of ours. We cannot assure you that we will be able to renew these borrowings when they become due or to obtain other loans or credits from other banks or other lenders on the terms satisfactory to us or at all to satisfy the substantial capital expenditure requirements associated with our capacity expansion, whether on our own or with the continuing support from Daqo Group. In addition, this level ofthe indebtedness could have an adverse

effect on our future operations, including, among other things: (1) reducing the availability of our cash flow to fund our working capital, capital expenditures or other general corporate purposes as a result of interest or principal payments; (2) subjecting us to the risk of interest rate increases on our indebtedness which bears floating interest rates; and (3) placing us at a competitive disadvantage compared to our competitors that have less debt or are otherwise less leveraged. Any of these factors could have a material and adverse effect on our business, financial condition and results of operations.

We plan to enter into the downstream wafer manufacturing business and we may not be successful in this new endeavor, which may adversely affect our business expansion strategies and harm our financial condition and results of operations.

We plan to expand into the wafer production business, which we believe will enable us to capture greater revenue opportunities and diversify business risks. Our ability to successfully implement our wafer business strategy is subject to various risks and uncertainties, including:

We used a portion of the proceeds from our initial public offering to finance capital expenditures for our wafer manufacturing business and if we cannot generate revenues or achieve profitability in this business as we expect, our financial condition will be adversely affected. In addition, our current management team has limited experience in this area and we will need to recruit additional skilled employees, including technicians and managers at different levels for our successful expansion into the wafer manufacturing business. All these factors and uncertainties may adversely affect our business expansion strategy and our financial condition and results of operations.

We have recently entered into the downstream module manufacturing business, and we may not be successful in this new endeavor, which may adversely affect our business expansion strategies.

We commenced commercial production of modules at our Nanjing facilities and shipped modules to customers in Europe in July 2010. To expand our module business, we plan to increase our production capacity from 50 MW as of June 30, 2010 to 200 MW in the third quarter of 2011. We have obtained the requisite permits for our module manufacturing business in Nanjing and are in the process of obtaining governmental approvals for our module capacity expansion plan. We expect to receive governmental approvals in the near future. However, if such approvals cannot be obtained in a timely manner, we may be required to suspend our module manufacturing expansion plan until such approvals are obtained, which could adversely affect our expansion strategies.

We currently source wafers and cells for our module production through direct purchases and tolling arrangements. If we cannot secure a stable supply of cells for our module production at reasonable prices, our ability to execute our expansion plan will be adversely and materially affected. Currently, due to the supply and demand imbalance in China’s photovoltaic cell market, there is a limited supply of high quality photovoltaic cells. We cannot assure you that such supply and demand imbalance will not continue or recur or we will be able to obtain sufficient cells in pace with the expansion of our module manufacturing capacity in the future.

We provide customers with a five-year limited product warranty against defective materials and workmanship and a 25-year limited power output warranty against loss in power for our module products. As a result, we bear the risk of extensive warranty claims long after we sell our products. If we experience a large amount of warranty claims in the future, we may incur significant repair and replacement costs associated with such claims. Furthermore, widespread product failures could harm our reputation and customer relationships and may cause our sales to decline, which in turn could have a material adverse effect on our financial condition and results of operations.

We may expandface risks and uncertainties expanding our business through alliances, joint ventures or acquisitionsacquisitions.

In 2011, we formed alliances with JNE Solar Inc., a party unrelated to us prior to this transaction, in Hamilton, Ontario, through our wholly owned subsidiary, Daqo New Energy Holdings (Canada) Ltd., to build and operate a solar module production facility in Hamilton, Ontario, Canada. Due to negative developments in the future.

Ifsolar photovoltaic market, we arediscontinued this project and terminated the joint venture in April 2012 without incurring any loss to us. We may in the future, if presented with appropriate opportunities, we may acquire or invest in technologies, businesses or assets that are strategically important to our business or form alliances with key players in the photovoltaic industry to further expand our business. Such acquisitions and investments could expose us to potential risks, including risks associated with the assimilation of new operations, technologies and personnel, unforeseen or hidden liabilities, the inability to generate sufficient revenues to offset the costs and expenses of acquisitions, and potential loss of, or harm to, our relationships with employees, customers and suppliers as a result of integration of new businesses. Investments in new businesses may also divert our cash flow from servicing our debts and making necessary capital expenditures. In addition, we may incur impairment losses on our acquisitions and investments in equity securities. The diversion of our management’s attention and any difficulties encountered with respect to the acquisitions, investments or alliances or in the process of integration could have an adverse effect on our ability to manage our business. Furthermore, our experience in the polysilicon manufacturing industry may not be as relevant or applicable in downstream markets. We may also face intense competition from companies with greater experience or established presence in the targeted downstream markets or competition from our industry peers with similar expansion plans. Any failure to integrate any acquired businesses or joint ventures into our operations successfully and any material liabilities or potential liabilities of any acquired businesses or joint ventures that are not identified by us during our due diligence process for such acquisitions or investments could materially and adversely affect our business and financial condition.

We will face risks associated with the marketing, distribution and sale of our photovoltaic products internationally, and if we are unable to effectively manage these risks, they could impair our ability to expand our business and operate profitably.

With our increased production, we intend to sell a portion of our products outside of China in the future. The marketing, distribution and sale of our polysilicon, wafers and modules in the international market would expose us to a number of risks, including:

If we are unable to effectively manage these risks, we may not be able to successfully expand our business abroad, operate profitably, fully utilize our existing and expanded capacity and grow our business as we have planned.

If we are unable to operate effectively or natural disasters or operational disruptions occur, our business, results of operations and financial condition could be adversely affected.

Production of polysilicon requires the use of volatile materials and chemical reactions sensitive to temperature and pressure and requires the use of external controls to maintain safety. For example, in the production of polysilicon, we use trichlorosilane, or TCS, which is a highly combustible substance if brought into contact with moisture in the air and is therefore potentially destructive and extremely dangerous if mishandled or used in uncontrolled circumstances. The occurrence of a catastrophic event involving TCS as a result of a natural disaster or human error at one of our polysilicon production facilities could threaten, disrupt or destroy a significant portion or all of our polysilicon production capacity at such facility for a significant period of time.

Additionally, the smooth operation of our polysilicon production facilities depends significantly on our ability to maintain temperatures and pressure at appropriate levels, the supply of steam at a consistent pressure level, the availability of adequate electricity and our ability to control the application of such electricity. Accordingly, mistakes in operating our equipment or an interruption in the supply of electricity or steam at our production facilities could result in the production of substandard polysilicon or substantial shortfalls in production and could reduce our production capacity for a significant period of time. In addition, we voluntarily shut down our manufacturing facilities from time to time on an as-needed basis for maintenance and quality check purposes. For example, we temporarily shut down our Phase 1 facilities in November 2009 for quality check purposes, in April 2010 for periodic maintenance, and in December 2010 for periodic maintenance and capacity enhancement, which hasand in December 2011 for periodic maintenance. From October 2012 to the date of the annual report, our polysilicon facilities in Wanzhou have been shut down for periodic maintenance, as well as equipment upgrades and technology improvements. These abovementioned shutdowns have reduced and may further reduce the volume and increase the cost of polysilicon we produce. In addition, we may need to use hazardous equipment for our wafer and module manufacturing processes.process. Such equipment requires skills and experience for safe operation. We could experience events such as equipment failures, explosions or fires due to employee errors, equipment malfunctions, accidents, and interruptions in electricity or water cooling supplies, natural disasters or other causes. In addition, such events could cause damage to properties, personal injuries or even deaths. As a result, we may in the future experience production curtailments or shutdowns or periods of reduced production. The occurrence of any such events or disruptions could result in loss of revenues and could also damage our reputation, any of which could have a material adverse effect on our business, operating results and financial condition.

We may not be successful in our efforts to continue to manufacture polysilicon in a cost-effective manner.

The technology used to manufacture polysilicon is complex, requires costly equipment and is continuously being modified in an effort to improve yields and product performance. We may face significant challenges relating to polysilicon production in the future. Microscopic impurities such as dust and other contaminants, difficulties in the manufacturing process, disruptions in the supply of utilities or defects in the key materials or tools used to manufacture polysilicon could interrupt manufacturing, reduce yields or cause a portion of the polysilicon to be rejected by our customers, which would materially and adversely affect our profitability.

Our effective capacity and ability to produce high volumes of polysilicon depend on the cycle time for each batch of polysilicon. We may encounter problems in our manufacturing process or facilities as a result of, among other things, production failures, construction delays, human error, equipment malfunction or process contamination, all of which could seriously harm our operations. We may experience production delays if any modifications we make in the manufacturing process to shorten production cycles are unsuccessful. Moreover, failure to achieve acceptable manufacturing levels may make our polysilicon costs uncompetitive, which could materially and adversely affect our business, financial condition and results of operations.

Further development in alternative polysilicon production technologies or other changes in the photovoltaic industry could render our production process too costly or obsolete, which could reduce our market share and cause our sales and profits to decline.

Although the vast majority of the polysilicon produced in the world utilizes the chemical vapor deposition process, or the “modified Siemens process,” several alternative production processes have been developed that may have significantly lower production costs. Compared with other polysilicon production processes, a disadvantage of the modified Siemens process is the large amount of electricity required. For example, MEMC, REC and Wacker currently operate or are constructing facilities that use the “fluidized bed reactor” method for producing polysilicon. Tokuyama has developed a polysilicon technology called the “vapor-to-liquid deposition” process. Other polysilicon manufacturers are establishing facilities using upgraded metallurgical grade silicon process to produce solar-grade polysilicon.

Further developments in competing polysilicon production technologies may result in lower manufacturing costs or higher product performance than those achieved from the modified Siemens process, including the one

we employ. We will need to invest significant financial resources in research and development to expand our market position, keep pace with technological advances in polysilicon production and effectively compete in the future. Failure to further refine our technology could make our production process too costly or obsolete, which could reduce our margins and market share, cause our revenues to decline and materially and adversely affect our results of operations.

Existing regulations and changes to these regulations may present technical, regulatory, economic and economictrade barriers to the purchase and use of photovoltaic products, which may significantly reduce demand for our products.

Photovoltaic products are subject to national and local regulations relating to building codes, safety, environmental protection, utility interconnection and metering and other aspects of the electric utility industry. In a number of countries, including China, these regulations are being modified and may continue to be modified. The purchases of, or further investment in the research and development of, alternative energy sources, including photovoltaic technology, could be deterred by unfavorable regulations, which could result in a significant reduction in the potential demand for our products. For example, without a regulatory mandated exception for solar power systems, electric utility companies are often charged interconnection or standby fees for putting distributed power generation on the electric utility grid. These fees could increase the cost to end users of using the photovoltaic products and make them less desirable,desirable. In addition, trade authorities in foreign countries may apply trade sanctions against photovoltaic product imports from China, if the foreign trade authorities determine that the export sales from China are in violation of fair trade practices. Such trade sanctions can result in significant additional duties, which will adversely affect our photovoltaic product demand and thereby harming our business, prospects, results of operations and financial condition.

A global financial and economic crisis, particularly a slowdown in the Chinese economy, may adversely affect our business, results of operations and financial condition.

The global financial crisis and economic downturn that unfolded in 2008 and continued in 2009 adversely affected economies and businesses around the world, including those in China. More recently, there has been concern over capital markets access and the solvency of certain European Union member states, and unrest in the Middle East and North Africa which has lead to higher oil prices. Since we currently derive substantially all of our revenues from customers in China, any prolonged slowdown in the Chinese economy may have an adverse effect on our business, operating results and financial condition in a number of ways. For example, our customers may decrease or delay spending with us, while we may have difficulty expanding our customer base fast enough, or at all, to offset the impact of decreased spending by our existing customers. In addition, to the extent we offer credit to any customer and such customer experiences financial difficulties due to the economic slowdown, we could have difficulty collecting payment from such customer.

We obtain certain production equipment from a limited number of suppliers, and if such equipment is not delivered on time, is damaged in shipment or is otherwise unavailable, our ability to deliver polysilicon on time will suffer, which in turn could result in cancellation of orders and loss of revenues.

Our operations and expansion plans depend on our ability to obtain a sufficient amount of equipment that meets our specifications on a timely basis. Some of our equipment used in polysilicon and wafer production is not readily available from alternative vendors and would be difficult to repair or replace if it were to become damaged or cease working. If any of these suppliers were to experience financial difficulties or go out of business, or if there were any damage to or a breakdown of our production equipment, our business would suffer.incur losses. In addition, a supplier’s failure to supply our ordered equipment in a timely manner, with adequate quality and on terms acceptable to us, could delay the capacity expansion of our manufacturing facilities and otherwise disrupt our production schedule or increase our costs of production. We have experienced significant delays in the delivery of our key equipment in the past. Failure to obtain equipment meeting our specifications could have a material adverse effect on our business, financial condition and results of operations. Furthermore, demand for polysilicon and wafer production equipment may result in significant increases in prices of such equipment or shortages in related components for our intended expansion. Any unexpected price increases could materially and adversely affect our financial condition and results of operations.

We have sourced and will continue to source some of our production equipment from Chinese manufacturers, and we cannot assure you that the China sourcedChina-sourced equipment will perform at the same level as our imported equipment or will meet our quality requirements.

We have purchased key equipment from Chinese and international suppliers. Compared to major international suppliers, our China-based suppliers generally have shorter operating histories and less experience in providing equipment for the polysilicon industry. We cannot assure you that the locally made equipment will perform at similar levels of quality and reliability as our imported equipment. In the event the China sourcedChina-sourced equipment does not perform as well as the imported equipment or does not perform at all, we may encounter disruption in our manufacture or deterioration of product quality, which in turn could materially and adversely affect our business, financial condition and results of operations.

Product defects could result in increased costs, decreased sales, and damage to our customer relationships and our reputation.

Our photovoltaic products may contain defects that are not detected until after it is shipped or processed by our customers. In the event our products are returned to us due to product defects, we would be required to replace the defective products promptly. If we deliver products with defects, or if there is a perception that our products are of substandard quality, we may incur substantially increased costs associated with termination of contracts and replacement of shipped products, and our credibility, market reputation and relationship with customers will be harmed and sales of our products may be materially and adversely affected.

MostSubstantially all of our production, storage, administrative, and research and development facilities are located in close proximity to one another ineither Chongqing or Xinjiang, China. Any damage or disruption at these facilities would have a material adverse effect on our financial condition and results of operations.

Substantially all of our production, storage, administrative, and research and development facilities are currently located in close proximity to one another ineither Chongqing or Xinjiang, China. A natural disaster,Natural disasters, such as fire, floods, typhoons, earthquakes, snow storms, or other unanticipated catastrophic events, including power interruption, telecommunications failures, equipment failures, explosions, break-ins, terrorist acts or war, could significantly disrupt our ability to manufacture our products and operate our business. If any of our production facilities or material equipment were to experience any significant damage or downtime, we would not be able to meet our production targets and our business would suffer.incur losses. Any damage or disruption at these facilities would have a material adverse effect on our business, financial condition and results of operations.

On May 12, 2008, an earthquake of a magnitude of 8.0 on the Richter scale hit the Sichuan Province, which is located adjacent to Chongqing. Businesses and production operations in the affected areas of Sichuan Province were shut down temporarily due to safety concerns. There can be no assurance that we may not be directly or indirectly affected by similar natural disasters in the future.

We rely on third party intellectual property for certain key aspects of our operations, which subjects us to the payment of license fees and potential disruption or delays in the production of our products.

While we continue to develop and pursue patent protection for our own technologies, we expect to continue to rely on third party license arrangements for certain key aspects of our operations. For instance, Poly Engineering S.r.l., or Poly Engineering, granted awe license tofrom third party hydrochlorination process technology for our company for the exclusive rights in China, Taiwan, Hong Kong and Macau to utilize its modified Siemens process to produce polysilicon in our facilities.production. See “Item 4. Information on the Company—B. Business Overview—Intellectual Property” for details of the contractual arrangements. The fees associated with such licenses could adversely affect our financial condition and operating results. If for any reason we are unable to license necessary technology on acceptable terms or at all, it may become necessary for us to develop alternative technology internally, which could be costly and delay or disrupt our production and therefore have a material adverse effect on our business and operating results.

Failure to protect our intellectual property rights may undermine our competitive position, and litigation to protect our intellectual property rights may be costly.

We rely primarily on trade secrets and other contractual restrictions to protect our intellectual property. Contractual arrangements, such as the confidentiality and non-competition agreements and terms between us and our research and development personnel, afford only limited protection and the actions we may take to protect our trade secrets and other intellectual property may not be adequate. In addition, we currently hold 16 patents and have ten16 pending patent applications in China covering various aspects of the polysilicon and wafer manufacturing process.processes. However, we cannot assure you that our patent applications will be eventually issued with sufficiently broad coverage to protect our technology and products. Failure to protect our intellectual property and proprietary rights may undermine our competitive position. Third parties may infringe or misappropriate our proprietary technologies or other intellectual property and proprietary rights and use them to compete against us, which could have a material adverse effect on our business, financial condition or operating results.

Policing unauthorized use of proprietary technology can be difficult and expensive. In particular, the laws and enforcement procedures of China and certain other countries are uncertain or do not protect intellectual property rights to the same extent as the laws and enforcement procedures of the United States do. See “—Risks Relating to Doing Business in China—Uncertainties in the interpretation and enforcement of Chinese laws and regulations could limit the legal protection available to you and us.” We may need to resort to court proceedings to enforce our intellectual property rights in the future. Litigation relating to our intellectual property might result in substantial costs and diversion of resources and management attention away from our business. An adverse determination in any such litigation will impair our intellectual property and proprietary rights and may harm our business, prospects and reputation.

We may be exposed to infringement or misappropriation claims by third parties, which, if determined adversely to us, could cause us to pay significant damage awards.

Although we are currently strengthening our research and development capability, to date, substantially all of the intellectual property used in our production process was developed by third parties. Our success will be jeopardized if we cannot use and develop our technology and know-how without infringing the intellectual property rights of third parties. The validity and scope of claims relating to photovoltaic technology patents involve complex scientific, legal and factual questions and analysis and, therefore, may be highly uncertain. We may be subject to litigation involving claims of patent infringement or violation of other intellectual property rights of third parties. The defense and prosecution of intellectual property suits, patent opposition proceedings, and related legal and administrative proceedings can be both costly and time-consuming and may significantly divert the efforts and resources of our technical and management personnel. An adverse determination in any such litigation or proceedings to which we may become a party could subject us to significant liability to third parties, require us to seek licenses from third parties, to pay ongoing royalties, or to redesign our manufacturing process or our products or subject us to injunctions prohibiting the manufacture and sale of our products or the use of our technologies. Protracted litigation could also result in our customers or potential customers deferring or limiting their purchase or use of our products until resolution of such litigation.

We may not be able to continue to receive the same level of support from Daqo Group, which may have a material adverse effect on our business and results of operations.

Since our inception, we have substantially benefited from financial support from Daqo Group, one of the largest electrical equipment manufacturers in China. As of December 31, 2010,2012, we had outstanding payables to and amount due from Daqo Group and its subsidiaries in the amount of $0.4 million. We also had prepayment obligations to Daqo Group in the amount of $0.9$23.7 million as we had contracted with Daqo Group to purchase certain machines and other equipment from third parties on our behalf. Daqo Group guarantees substantially all of our outstanding bank borrowings.$6.6 million, respectively. In addition, Daqo Group has granted us a permanent and royalty-free license to use the “Daqo” brand, which is a well recognizedwell-recognized brand in the electrical industry in China. We have benefited from the strong brand recognition of

“Daqo” “Daqo” in our business development efforts, as evidenced by our ability to secure major customers based in China within a short period after we commenced commercial production of polysilicon. Daqo Group has agreed in writing not to engage in the business of manufacturing, marketing or distributing polysilicon or any other solar power products anywhere in the world or compete in any manner with our businesses without our consent for an indefinite term. Daqo Group has committed to provide any necessary financial support to us, as may be required, evidenced by a signed letter of support. However, we cannot assure you that we will continue to receive the same level of support, or any support at all, from Daqo Group in the future. If Daqo Group ceases to support us, our business, results of operations and prospects may be materially and adversely affected. In addition, any negative publicity associated with Daqo Group will likely have an adverse impact on our reputation, which could materially and adversely affect our business. In the event of any disagreements with Daqo Group, we may have to resort to legal proceedings in China to enforce our rights, which could be costly, time consuming and involve uncertain outcome.

Our business depends substantially on the continuing efforts of our executive officers and key employees, and our business may be severely disrupted if we lose their services.

Our future success depends substantially on the continued services of our executive officers and key employees, especially Mr. Guangfu Xu, our chairman, and Dr. Gongda Yao, our chief executive officer. If one or more of our executive officers or key employees were unable or unwilling to continue in their present positions, we might not be able to replace them easily, in a timely manner, or at all. Our business may be severely disrupted, our financial conditions and results of operations may be materially and adversely affected and we may incur additional expenses to recruit, train and retain personnel. If any of our executive officers or key employees join a competitor or form a competing company, we may lose customers, suppliers, know-how and key professionals and staff members. Each of our executive officers and key employees has entered into an employment agreement with us, which contains non-competition provisions. However, if any dispute arises between our executive officers and us, these agreements may not be enforceable in China, where these executive officers reside, in light of uncertainties with China’s legal system. See “—Risks Relating to Doing Business in China—Uncertainties in the interpretation and enforcement of Chinese laws and regulations could limit the legal protection available to you and us.”

Certain of our principal shareholders have substantial influence over our company and their interests may not be aligned with the interests of our other shareholders.

As of the date of this annual report, four of our directors, Messrs. Guangfu Xu, Xiang Xu Fei Ge and Dafeng Shi, our directors that are affiliated with Daqo Group, beneficially own an aggregate of 42.9%35.5% of our outstanding share capital. These four shareholders are also directors of Daqo Group or Daqo Group’s material subsidiaries. As a result of their high level of shareholding, these shareholders have substantial influence over our business, including decisions regarding mergers, consolidations and the sale of all or substantially all of our assets, election of directors and other significant corporate actions. These shareholders may take actions that are not in the best interest of us or our other shareholders. This concentration of ownership may discourage, delay or prevent a change in control of our company, which could deprive our other shareholders of an opportunity to receive a premium for their shares as part of a sale of our company and might reduce the price of our ADSs. These actions may be taken even if they are opposed by our other shareholders. These shareholders’ interests as beneficial owners of Daqo Group and Daqo New Material may not always be aligned with their interests as our shareholders. Should any conflict of interest arise, these shareholders may take actions not in the best interest of us and our other shareholders.

If we are unable to attract, train and retain qualified personnel, our business may be materially and adversely affected.

Our future success depends, to a significant extent, on our ability to attract, train and retain qualified personnel, particularly technical personnel with expertise in the photovoltaic industry. Since our industry is characterized by high demand and intense competition for talent, there can be no assurance that we will be able to attract or retain qualified technical staff or other highly skilled employees that we will need to achieve our

strategic objectives, including our initiatives to expand downstream into the wafer and cell manufacturing businesses and to ramp up our module manufacturing capacity.objectives. As we have a limited operating history and are stillin a relatively young company and our business has grown rapidly,stage of rapid growth, despite recent set-backs, our ability to train and integrate new employees into our operations may not meet the growing demands of our business. If we are unable to attract and retain qualified personnel, our business may be materially and adversely affected.

Compliance with environmental regulations can be expensive, and non-compliance with these regulations may result in adverse publicity and potentially significant monetary damages and fines.

As our manufacturing processes generate waste water and gas and other industrial wastes, we are required to comply with all applicable regulations regarding protection of the environment. We are in compliance with present environmental protection requirements and have all the necessary environmental permits to conduct our business in all material respects. However, if more stringent regulations are adopted in the future, the cost of compliance with these new regulations could be substantial. If we fail to comply with present or future environmental regulations, we may be required to pay substantial fines, suspend production or cease operations, which in turn would have a material adverse effect on our financial condition and results of operations.

Our expansion in Xinjiang, China may not be successful.

We commenced construction of our Phase 2 polysilicon facilities in Shihezhi, Xinjiang Uyghur Autonomous Region in March 2011 and plan to start commercial production at these facilities in the fourth quarter of 2012. Although the Xinjinag location provides many strategic advantages, including lower electricity costs, it is uncertain whether our expansion in Xinjinag will be successful.

There are many risks associated with the our expansion in Xinjiang, including:

One or more of these factors could harm our Xinjiang operations and consequently, could adversely affect our overall operating results.

The discontinuation of any of the preferential tax treatments or the financial incentives and grants currently available to us in China could adversely affect our overall results of operations.

Various Chinese governmental authorities have provided tax incentives to our subsidiaries in China. These incentives include income tax exemption or reduced enterprise income tax rates. For example, under the PRC Enterprise Income Tax Law, or the EIT Law, which became effective on January 1, 2008, the statutory enterprise income tax rate is 25%. However, our Chinese subsidiary Chongqing Daqo New Energy Co., Ltd., or Chongqing Daqo, as a foreign-invested enterprise established in the central“Chongqing Municipality High and western regions of China, wasNew Technology Enterprise,” is entitled to a preferential enterprise income tax rate of 15% through 2010. In December 2009, Chongqing Daqo was qualified as a “Chongqing Municipality High and

New Technology Enterprise.” This will entitle it to a preferential enterprise income tax rate of 15% for three years from the grant date of the certificate. The status is valid until November 2015 and can be renewed for additional three-year terms upon Chongqing Daqo’s application and the government’s approval. If there are significant changes in the business operations, manufacturing technologies or other criteria that cause the enterprise to no longer meet the criteria as a “high and new technology enterprise,” such status will be terminated from the year of such change. We cannot assure you that Chongqing Daqo will continue to qualify as a “high and new technology enterprise” in future periods. In addition, Chongqing Daqo has received various financial incentives and grants from the local government since its inception. For example, it received government grants in the amount of $2.8$11.0 million and $9.2 million in 2010.2011 and 2012, respectively. Any increase in the enterprise income tax rate applicable to our Chinese subsidiaries or discontinuation or reduction of any of the preferential tax treatments or financial incentives currently enjoyed by our subsidiaries in China could adversely affect our business, operating results and financial condition.

The dividends we receive from our Chinese subsidiaries and our global income may be subject to Chinese tax under the EIT Law, which would have a material adverse effect on our results of operations; our foreign ADS holders will be subject to a Chinese withholding tax upon the dividends payable by us, if we are classified as a Chinese “resident enterprise.”

Under the Chinese enterprise income tax laws and regulations, dividends, interests, rent, royalties and gains on transfers of property payable by a foreign-invested enterprise in China to its foreign investor who is a non-resident enterprise will be subject to a 10% withholding tax, unless such non-resident enterprise’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced rate of withholding tax.tax and such non-resident enterprise is the beneficial owner of the dividends, interests, rent, royalties and gain on transfers of property. The Cayman Islands, where Daqo Cayman is incorporated, does not have such a tax treaty with China.

Under the EIT Law, an enterprise established outside China with its “de facto management body” within China is considered a “resident enterprise” in China and will be subject to the Chinese enterprise income tax at the rate of 25% on its worldwide income. In April 2009, the Chinese State Administration of Taxation issued a new circular to clarify criteria for determining the “resident enterprise” status of foreign companies which are controlled by enterprises incorporated in China. Pursuant to the circular, to determine whether a company formed outside of mainland China and controlled by an enterprise incorporated in China should be treated as a Chinese resident enterprise, the tax authority will review factors such as the routine operation of the organizational body that effectively manages the enterprise’s production and business operations, locations of personnel holding decision-making power, location of finance and accounting functions and properties of the enterprise, and whether more than half of the directors or senior management personnel residing in China. Substantially all of our management members are based in China. However, it remains unclear how PRC tax authority will treat an overseas company controlled by PRC natural persons rather than PRC enterprises like our case. If the Chinese tax authorities subsequently determine that Daqo Cayman should be classified as a resident enterprise, then our worldwide income will be subject to Chinese income tax, which may have a material adverse effect on our financial condition and results of operations. Notwithstanding the foregoing provision, the EIT Law also provides that, if a resident enterprise directly invests in another resident enterprise, the dividends received by the investing resident enterprise from the invested enterprise are exempted from income tax, subject to certain conditions. Therefore, if Daqo Cayman is classified as resident enterprise under the EIT Law, the dividends received from our Chinese subsidiaries may be exempted from withholding tax.

Moreover, under the EIT Law, foreign ADS holders will be subject to a 10% withholding tax upon dividends payable by us if Daqo Cayman is classified as resident enterprise under the EIT Law. Any such tax may reduce the returns on your investment in our ADSs.

We rely on a lease agreement with Daqo New Material for material property, plant and equipment necessary for our production, and if Daqo New Material fails to perform, or terminates the lease agreement for any reason, our business could be disrupted.

Chongqing Daqo leases certain property, plant and equipment from Daqo New Material for its polysilicon production under a lease agreement effective from July 1, 2008, which was subsequently amended. When the

initial term expires on December 31, 2013, Chongqing Daqo has an option to renew the lease agreement on the same conditions for additional terms. If Daqo New Material fails to perform or terminates the lease agreement for any reason, including, for example, due to its breach of the agreement or the unavailability of any required governmental approvals, or if it refuses to extend or renew the lease agreement when the agreement expires, and we cannot find an immediately available alternative source for leasing similar property, plant and equipment, then our ability to carry on our operations will be impaired. If Daqo New Material fails to perform its obligations, we may need to initiate legal procedures in courts to enforce the agreement. Such procedures can be lengthy and the result may not be favorable to us.

We have limited insurance coverage. In particular, we do not have any product liability insurance or business interruption insurance.

As the insurance industry in China is still in an early stage of development, the product liability insurance and business interruption insurance available in China offer limited coverage compared to that offered in many other countries. We do not have any product liability insurance or business interruption insurance. Any business disruption or natural disaster could result in substantial costs and a diversion of resources, which would have a material adverse effect on our business and results of operations.

As with other photovoltaic product manufacturers, we are exposed to risks associated with product liability claims if the use of our photovoltaic products results in injury. Since our polysilicon products are made into electricity generating devices, it is possible that users could be injured or killed by devices that use our products as a result of product malfunctions, defects, improper installation or other causes. We only began commercial shipment of our photovoltaic products in July 2008 and, because of our limited operating history, we cannot predict whether product liability claims will be brought against us in the future or the effect of any resulting negative publicity on our business. The successful assertion of product liability claims against us could result in potentially significant monetary damages and require us to make significant payments.

In the course of the preparation and audit of our financial statements as of and for the years ended December 31, 2009 and 2010, we and our independent auditors, respectively, noted one material weakness and one significant deficiency in our internal control over financial reporting. We may incur extra costs in implementing measures to address such weakness and deficiency. If we fail to implement and maintain an effective system of internal controls, we may be unable to accurately report our results of operations or prevent fraud, and investor confidence and the market price of our ADSs may be materially and adversely affected.

Prior to our initial public offering in October 2010, we were a private company with limited accounting personnel and other resources with which to address our internal controls over financial reporting. Our independent registered public accounting firm has not conducted an audit of our internal control over financial reporting. However, in connection with the audits of our consolidated financial statements as of and for the years ended December 31, 2009 and 2010, we and our independent registered public accounting firm identified one “material weakness” and one “significant deficiency” in our internal control over financial reporting, as defined in the standards established by the Public Company Accounting Oversight Board of the United States. The material weakness identified related to our lack of sufficient accounting resources and expertise necessary to comply with U.S. GAAP and the Securities and Exchange Commission, or the SEC, reporting and compliance requirements. The significant deficiency identified related to our lack of sufficient and formally documented procedures for the financial closing and reporting process.

In compliance with Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, and its applicable rules and regulations, we have taken certain steps to remedy the material weakness and the significant deficiency, including hiring an outside consulting firm to review our internal control processes, policies and procedures in order to assist us in identifying any weaknesses or deficiencies in our internal control over financial reporting.

We will continue to implement measures during 2011 to remedy the material weakness and the significant deficiency, including:

We are working to implement these measures, although we cannot assure you that we will complete such implementation in a timely manner.

As a public company in the United States subject to the Sarbanes-Oxley Act of 2002, Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, requires that we include a report of management on our internal control over financial reporting in our annual report on Form 20-F beginning with our annual report for the fiscal year ending December 31, 2011. In addition, our independent registered public accounting firm must report on the effectiveness of our internal control over financial reporting. Our management may conclude that our internal control over financial reporting is not effective. Moreover, even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm, after conducting its own independent testing, may issue a report that is adverse if it is not satisfied with our internal controls or the level at which our controls are documented, designed, operated or reviewed, or if it interprets the relevant requirements differently from us. In addition, our reporting obligations may place a significant strain on our management, operational and financial resources and systems for the foreseeable future.

During the course of documenting and testing our internal control procedures in order to satisfy the requirements of Section 404, we may identify other deficiencies in our internal control over financial reporting. In addition, if we fail to maintain the adequacy of our internal control over financial reporting, as these standards are modified, supplemented or amended from time to time, we may not be able to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404. If we fail to achieve and maintain an effective internal control environment, we could suffer material misstatements in our financial statements and fail to meet our reporting obligations, which would likely cause investors to lose confidence in our reported financial information. This could harm our operating results and lead to a decline in the trading price of our ADSs. Additionally, ineffective internal control over financial reporting could expose us to increased risk of fraud or misuse of corporate assets and subject us to potential delisting from the stock exchange on which we list, regulatory investigations and civil or criminal sanctions.

We have granted, and may continue to grant, stock options and other share-based compensation in the future, which may materially impact our future results of operations.

We adopted our 2009 share incentive plan, or the Option Plan, in August 2009 that permits the grant of stock options, restricted shares and restricted share units to employees, directors and consultants of our company. Under the 2009 share incentive plan,Option Plan, we may issue options to purchase up to 15,000,000 ordinary shares. As of the date of this annual report, options to purchase 7,660,0008,990,000 ordinary shares have been granted under this plan. In addition, we modified the exercise prices for certain outstanding options in January 2012 and April 2013 in order to provide additional incentives to our employees and directors pursuant to an express authorization under our share incentive plan allowing our board of directors to approve a downward adjustment of the option exercise prices without shareholders’ approval. As a result of these option grants, option re-pricings and potential future grants under the plan, we have incurred, and will incur in future periods, significant share-based compensation expenses. We account for compensation costs for all stock options using a fair-value based method and recognize expenses in our consolidated statement of income in accordance with the relevant rules in accordance with U.S. GAAP, which may have a material adverse effect on our net income. Moreover, the additional expenses associated with share-based compensation may reduce the attractiveness of such incentive plan to us. However, if we limit the scope of our share incentive plan, we may not be able to attract or retain key personnel who are expected to be compensated by incentive shares or options.

Risks Relating to Doing Business in China

Changes in China’s economic, political or social conditions or government policies could have a material adverse effect on our business and operations.

Substantially all of our assets are located in and substantially all of our revenues are currently sourced from China. Accordingly, our business, financial condition, results of operations and prospects may be influenced to a significant degree by political, economic and social conditions in China generally and by continued economic growth in China as a whole.

The Chinese economy differs from the economies of most developed countries in many respects, including the level of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. Although the Chinese government has implemented measures since the late 1970s emphasizing the utilization of market forces for economic reform, the reduction of state ownership of productive assets and the establishment of improved corporate governance in business enterprises, a substantial portion of productive assets in China is still owned by the Chinese government. In addition, the Chinese government continues to play a significant role in regulating industry development by imposing industrial policies. The Chinese government also exercises significant control over the Chinese economic growth through the allocation of resources, controlling payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies.

While the Chinese economy has experienced a significant growth over the past decades, growth has been uneven, both geographically and among various sectors of the economy. The Chinese government has implemented various measures to encourage economic growth and guide the allocation of resources. Some of these measures benefit the overall Chinese economy, but may also have a negative effect on us. For example, our operating results and financial condition may be adversely affected by government control over capital investments or changes in tax regulations that are applicable to us, and by government policies or guidance aimed at curtailing the perceived over-capacity of certain industry sectors, such as steel, concrete, polysilicon and wind power equipment. See “Item 4. Information on the Company—B. Business Overview—Regulation—Renewable Energy Law and Other Government Directives.” The Chinese government has implemented certain measures, including interest rate increases, to control the pace of economic growth. These measures may cause decreased economic activity in China, which could in turn reduce the demand for our services and materially and adversely affect our operating results and financial condition.

A severe and prolonged global economic recession and the corresponding slowdown in the Chinese economy may adversely affect our business, results of operations and financial condition.

The global financial markets experienced significant disruptions in 2008 and the United States, Europe and other economies went into recession. The recovery from the lows of 2008 and 2009 was uneven and is facing new challenges, including the escalation of the European sovereign debt crisis since 2011 and the slowdown of the Chinese economy in 2012. It is unclear whether the European sovereign debt crisis will be contained and whether the Chinese economy will resume its high growth rate. There is considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies that have been adopted by the central banks and financial authorities of some of the world’s leading economies, including China’s. There have also been concerns over unrest in the Middle East and Africa, which have resulted in volatility in oil and other markets, and over the possibility of a war involving Iran. There have also been concerns about the economic effect of the earthquake, tsunami and nuclear crisis in Japan and tensions in the relationship between China and Japan. Economic conditions in China are sensitive to global economic conditions. Any prolonged slowdown in the global or Chinese economy may have a negative impact on our business, results of operations and financial condition, and continued turbulence in the international markets may adversely affect our ability to access the capital markets to meet liquidity needs.

Since we derive substantially all of our revenues from customers in China, any prolonged slowdown in the Chinese economy may have a negative impact on our business, results of operations and financial condition in a number of ways. For example, our customers may reduce or delay spending with us, while we may have difficulty expanding our customer base fast enough, or at all, to offset the impact of decreased spending by our existing customers. In addition, to the extent we offer credit to any customer and such customer experiences financial difficulties due to the economic slowdown, we could have difficulty collecting payment from such customer.

Uncertainties in the interpretation and enforcement of Chinese laws and regulations could limit the legal protection available to you and us.

The Chinese legal system is a civil law system based on written statutes. Unlike common law systems, it is a system in which legal decisions have limited value as precedents. In the late 1970s, the Chinese government began to promulgate a comprehensive system of laws and regulations governing economic matters in general. The overall effect of legislation over the past three decades has significantly increased the protections afforded to various forms of foreign or private-sector investment in China. Our Chinese operating subsidiaries,subsidiary, Chongqing Daqo, is a foreign-invested enterprise and Nanjing Daqo, are foreign-invested enterprises and areis subject to laws and regulations applicable to foreign-invested enterprises as well as various Chinese laws and regulations generally applicable to companies in China. Our business is also subject to various industry policy, safety and environmental laws and regulations that affect our operations and production facility expansion plans, including those related to investment, project construction, building, zoning, fire prevention and work safety. These laws and regulations are still evolving, and their interpretation and enforcement involve uncertainties. In addition, due to the inconsistent nature of regulatory enforcements in China, local Chinese governmental authorities have significant discretion in interpreting and implementing rules and regulations, and there is no assurance that the central government authorities will always agree with the interpretations and implementations of the local governmental authorities. Currently, all governmental approvals relating to our operations and production capacity expansion plans have been issued by the relevant competent local government authorities. However, if a central government agency

requires us to obtain its approval and if we fail to obtain such approval in a timely manner, or at all, we may be subject to the imposition of fines against us, or the suspension or cessation of our production capacity expansion plans. In addition, under the measures jointly issued by the National Development and Reform Commission, or NDRC, and nine other governmental agencies in September 2009, we will need to seek pre-approval from NDRC if we plan to further expand our production capacity beyond Phase 2. As the detailed guidelines for approval criteria or timeline under these measures have yet to be promulgated, we cannot assure you that we will obtain the required NDRC approval in time or at all if we plan to further expand our production capacity beyond Phase 2. See “Item 4. Information on the Company—B. Business Overview—Regulation—Renewable Energy Law and Other Government Directives.” It may be more difficult to evaluate the outcome of any regulatory or legal proceedings and the level of legal protection we enjoy than in more developed legal systems. These uncertainties may impede our ability to continue our operations or planned capacity expansions, which, as a result, could materially and adversely affect our business and operations.

Chinese regulations relating to offshore investment activities by Chinese residents may increase the administrative burden we face and may subject our Chinese resident beneficial owners or employees to personal liabilities, limit our subsidiaries’ ability to increase its registered capital or distribute profits to us, limit our ability to inject capital into our Chinese subsidiaries, or may otherwise expose us to liability under Chinese law.

SAFE has promulgated regulations that require Chinese residents and Chinese corporate entities to register with local branches of SAFE in connection with their direct or indirect offshore investment activities. These regulations may apply to our shareholders who are Chinese residents and may apply to any offshore acquisitions that we make in the future.

In October 2005, SAFE issued a regulation entitled “Circular on Issues Concerning Foreign Exchange Regulation of Corporate Financing and Roundtrip Investments by Chinese Residents through Offshore Special Purpose Companies,” or SAFE Circular No. 75. SAFE Circular No. 75 requires Chinese residents to register with the local SAFE branch before establishing or controlling any company outside of China for the purpose of capital financing with assets or equities of Chinese companies, referred to in the notice as an “offshore special purpose company.” In addition, any Chinese resident who is a direct or indirect shareholder of an offshore company is required to update his registration with the relevant SAFE branches, with respect to that offshore company, any material change involving increase or decrease of capital, transfer or swap of shares, merger, division, equity or debt investment or creation of any security interest. Moreover, the Chinese subsidiaries of that offshore company are required to coordinate and supervise the filing of SAFE registrations by the offshore company’s shareholders who are Chinese residents in a timely manner. If a Chinese shareholder with a direct or indirect stake in an offshore parent company fails to make the required SAFE registration, the Chinese subsidiaries of such offshore parent company may be prohibited from making distributions of profit to the offshore parent and from paying the offshore parent proceeds from any reduction in capital, share transfer or liquidation in respect of the Chinese subsidiaries, and the offshore parent company may also be prohibited from injecting additional capital into its Chinese subsidiaries. Furthermore, failure to comply with the various SAFE registration requirements described above may result in liability for the Chinese shareholders and the Chinese subsidiaries under Chinese law for foreign exchange registration evasion.

We have, up to the present, completed the SAFE Circular No. 75 registration for all current beneficial shareholders of our company who are Chinese residents. However, we may not be fully informed of the identities of the beneficial owners of our company in the future and we cannot assure you that all of our Chinese resident beneficial owners will comply with the SAFE regulations. The failure of our beneficial owners who are Chinese residents to make any required registrations may subject us to fines and legal sanctions, and prevent us from being able to make distributions or pay dividends, as a result of which our business operations and our ability to distribute profits to you could be materially and adversely affected.

Participants of our share incentive plan who are PRC individuals are required to register with SAFE, and the failure to so comply could subject us and such participants to penalties.

On March 28, 2007,In February 2012, the SAFE issuedpromulgated the Operating ProceduresNotice on the Administration of Foreign Exchange Regarding Chinese Individuals’ ParticipationMatters for Domestic Individuals Participating in Employee Share Ownership Plans and Employeethe Stock Option

Incentive Plans of Overseas Listed Companies, or the Stock Option Rule. UnderNotice. According to the Stock Option Rule, Chinese citizens who are granted stock options by an overseas publicly listed company are required, throughNotice, a ChinesePRC domestic qualified agent or Chinesethe PRC subsidiary of such overseas publicly listed company must file an application with the SAFE or its local counterpart on behalf of PRC resident individuals who participate in stock incentive plans of overseas publicly-listed companies to registerobtain approval for an annual allowance with SAFE and complete certain other procedures. We and our Chinese employees who have been granted stock options are subjectrespect to the Stock Option Rule aspurchase of foreign exchange in connection with the stock holding or share option exercises. Our company is an “overseas publicly-listed company,” and therefore, we are an overseas publicly listed company. and we are in the processparticipants of registering our share incentive plan and completing other processwho are PRC individuals are subject to these regulations.

We are in the progress of submitting an application with the SAFE or its local counterpart to register our share incentive plan. If our application is unsuccessful or our option plan participants who are PRC individuals fail to work with us to complete the registration, we or our Chinese employees fail to comply with such regulation, we or our employeespersons may be subject to fines and legal sanctions. Any failure to comply with such regulations may subject us and the relevant participants of our share incentive to fines and legal sanctions and prevent us from being able to grant share incentive to our personnel, as a result of which our business operations may be adversely affected.

Chinese regulation of direct investment and loans by offshore holding companies to Chinese entities may delay or limit us from making additional capital contributions or loans to our Chinese subsidiaries.

Any capital contributions or loans that we, as an offshore entity, make to our Chinese subsidiaries, are subject to Chinese regulations. For example, for each of our Chinese subsidiary, the aggregate amount of our loans to the Chinese subsidiary cannot exceed the difference between the amount of its total investment and its registered capital as approved by the foreign investment regulatory authorities under relevant Chinese laws, and the loans must be registered with the local branch of the SAFE. For each foreign invested enterprise, such as Chongqing Daqo and Nanjing Daqo, when the Chinese foreign investment regulatory authorities approve the establishment of such foreign invested enterprise, the authorities approve the amounts of such enterprise’s registered capital, which represent the investors’ capital commitment in equity, and the amounts of its total investment, which represent the sum of its registered capital plus the amounts of its permitted loans. After the establishment of the foreign invested enterprise, the investors can seek regulatory approval to increase its registered capital and the total investment amounts, and upon approval, there will be increases in both amounts. There is a specific statutory guideline relating to the ratio of a foreign invested enterprise’s registered capital amount over total investment amount, and all foreign investment regulatory authorities in China must follow the ratio guideline when exercising their approval authority. However, there is no uniform statutory guideline applicable to all regulatory authorities regarding whether to approve the establishment of a new foreign invested enterprise or to approve any increase in the registered capital and total investment of an existing foreign invested enterprise. In practice, authorities consider factors such as overall governmental policies relating to the specific industry and demands in a particular industry and the approval usually takes one to three months depending on the locations of the foreign invested enterprises. The amounts of the approved total investmentsinvestment amounts of Chongqing Daqo and NanjingXinjiang Daqo New Energy Co., Ltd., or Xinjiang Daqo, are $286.0 million and $48.9$298.0 million, respectively. The amount of the registered capital of Chongqing Daqo is $96.0 million, of which $69.6 million of which has beenwas contributed by Daqo Cayman as the sole investor. The amount of the registered capital of NanjingXinjiang Daqo is $20.0$100.0 million, of which has been$38.4 million was contributed by Daqo Cayman as the sole investor. As of December 31, 2010,a result, the amount of loansmaximum permissible amounts that Chongqing Daqo was permitted toand Xinjiang Daqo may borrow from Daqo Cayman cannot exceed $125.0are $190.0 million and that for Nanjing Daqo cannot exceed $28.9 million.$198.0 million, respectively. We may not make loans to Chongqing Daqo and Nanjingor Xinjiang Daqo in excess of the maximum amounts permissible unless we obtain government approval to increase their total investment amounts. In addition, any increases of our capital contributions to our Chinese subsidiaries beyond the previously authorized amount must be approved by the MOFCOM and the National Development and Reform CommissionNDRC or their respective local counterparts. We cannot assure you that we will be able to obtain these approvals on a timely basis, or at all. If we fail to obtain such approvals, our ability to make equity contributions or provide loans to our Chinese subsidiaries or to fund their operations may be negatively affected, which could adversely affect our Chinese subsidiaries’ liquidity and their ability to fund their working capital and expansion projects and meet their obligations and commitments.

We rely principally on dividends and other distributions on equity paid by our wholly owned operating subsidiaries to fund any cash and financing requirements we may have, and any limitation on the ability of our operating subsidiaries to pay dividends to us could have a material adverse effect on our ability to borrow money or pay dividends.

As a holding company, we rely principally on dividends and other distributions on equity paid by our Chinese subsidiaries for our cash requirements, including funds necessary to service any debt we may incur. If our Chinese subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may

restrict their ability to pay dividends or make other distributions to us. Furthermore, relevant Chinese laws and regulations permit payments of dividends by Chinese subsidiaries only out of their retained earnings, if any, determined in accordance with Chinese accounting standards and regulations. Under Chinese laws and regulations, each of our Chinese subsidiaries is required to set aside a portion of its net income each year to fund a statutory surplus reserve until such reserve reaches 50% of its registered capital. This reserve is not distributable as dividends. As a result, our Chinese subsidiaries are restricted in their ability to transfer a portion of their net assets to us in the form of dividends, loans or advances. Limitation on the ability of our Chinese subsidiaries to pay dividends to us could materially and adversely limit our ability to borrow money outside of China or pay dividends to holders of our ADSs. Also see “—Risks Relating to Our Business—The dividends we receive from our Chinese subsidiaries and our global income may be subject to Chinese tax under the EIT Law, which would have a material adverse effect on our results of operations; our foreign ADS holders will be subject to a Chinese withholding tax upon the dividends payable by us, if we are classified as a Chinese “resident enterprise.”

Fluctuations in exchange rates could result in foreign currency exchange losses.

The conversion of RenminbiRMB into foreign currencies, including U.S. dollars, is based on rates set by the People’s Bank of China. The PRC government allowed the RenminbiRMB to appreciate by more than 20% against the U.S. dollar between July 2005 and July 2008. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the RenminbiRMB and the U.S. dollar remained within a narrow band. Since June 2010, the PRC government has allowed the RenminbiRMB to appreciate slowly against the U.S. dollar again.again, though there have been periods when the U.S. dollar has appreciated against the Renminbi as well. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RenminbiRMB and the U.S. dollar in the future. As a consequence, the Renminbi has fluctuated sharply since July 2008 against other freely traded currencies, in tandem with the U.S. dollar. For example, the Renminbi appreciated approximately 27% against the Euro between July 2008 and November 2008. In June 2010, the PRC government announced that it would increase Renminbi exchange rate flexibility. However, it remains unclear how this policy will be implemented. There remains significant international pressure on the Chinese government to adopt a substantial liberalization of its currency policy, which could result in a further and more significant appreciation in the value of the Renminbi against the U.S. dollar. Significant revaluation of the Renminbi may have a material adverse effect on your investment. In addition, appreciation of the Renminbi against the U.S. dollar would increase our production costs. Conversely, if we decide to convert our Renminbi into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs or for other business purposes, appreciation of the U.S. dollar against the Renminbi would have a negative effect on the U.S. dollar amount available to us.

Failure to maintain effective internal control over financial reporting could have a material and adverse effect on the trading price of our ADSs.

We are subject to the reporting obligations under the U.S. securities laws. In connection with the audit of our internal control over financial reporting as of and for the year ended December 31, 2011, we and our independent registered public accounting firm identified three “material weaknesses” including (i) our lack of accounting resources and expertise necessary to comply with U.S. GAAP and the Securities and Exchange Commission financial reporting and disclosure requirements, (ii) our lack of sufficient resources to perform thorough reviews of consolidated financial statements and related footnote disclosures during the period-end financial reporting and disclosure process, and (iii) our lack of sufficient processes, documentation and approval of related party transactions with affiliates. In 2012, we have made enhancements to our internal controls over financial reporting. See “Part II—Item 5. Controls and Procedures—Remediation and Changes in Internal Control Over Financial Reporting.” Based on these actions taken and our testing and evaluation of the effectiveness of our internal controls, we have concluded the material weaknesses no longer existed as of December 31, 2012.

However, although our management concluded that we maintained effective internal control over financial reporting as of December 31, 2012, we cannot assure you that we will maintain effective internal control over financial reporting on an ongoing basis. If we fail to maintain effective internal control over financial reporting, we will not be able to conclude and our independent registered public accounting firm will not be able to report ( if it is required to report) that we have effective internal control over financial reporting in accordance with the Sarbanes-Oxley Act of 2002 in our future annual report on Form 20-F covering the fiscal year in which this failure occurs. Effective internal control over financial reporting is necessary for us to produce reliable financial reports. Any failure to maintain effective internal control over financial reporting could result in the loss of investor confidence in the reliability of our financial statements, which in turn could have a material and adverse effect on the trading price of our ADSs. Furthermore, we may need to incur additional costs and use additional management and other resources as our business and operations further expand or in an effort to remediate any significant control deficiencies that may be identified in the future.

We may be adversely affected by the outcome of the administrative proceedings brought by the SEC against five accounting firms in China.

Recently, the SEC commenced administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002 against the Chinese affiliates of the ‘‘big four’’ accounting firms, including our auditors, and also against BDO China Dahua. The Rule 102(e) proceedings initiated by the SEC relate to these firms’ failure to produce documents, including audit workpapers, to the request of the SEC pursuant to Section 106 of the Sarbanes-Oxley Act of 2002, as the auditors located in the PRC are not in a position lawfully to produce documents directly to the SEC because of restrictions under PRC law and specific directives issued by the China Securities Regulatory Commission. As the administrative proceedings are ongoing, it is impossible to determine their outcome or the consequences thereof to us. The issues raised by the proceedings are not specific to our auditors. or to us, but affect equally all audit firms based in China and all China-based businesses with securities listed in the United States. However, if the administrative judge were to find in favor of the SEC under the proceeding and depending upon the remedies sought by the SEC, these audit firms could be barred from practicing before the SEC. As a result, listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which may result in their delisting. Moreover, any negative news about the proceedings against these audit firms may erode investor confidence in China-based, United States listed companies and the market price of our ADSs may be adversely affected.

Our auditor, like other independent registered public accounting firms operating in China, is not permitted to be subject to inspection by Public Company Accounting Oversight Board, and consequently, investors may be deprived of the benefits of such inspection.

The independent registered public accounting firm that issues the audit reports included in this annual report, as an auditor of companies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board (United States), or PCAOB, is required by the laws of the United States to undergo regular inspections by the PCAOB to assess its compliance with the laws of the United States and with applicable professional standards. Because our auditor is located in China, a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the PRC authorities, our auditor, like other independent registered public accounting firms operating in China, is currently not inspected by the PCAOB.

Inspections of other firms that the PCAOB has conducted outside of China have identified deficiencies in those firms’ audit procedures and quality control procedures, and such deficiencies may be addressed as part of the inspection process to improve future audit quality. The inability of the PCAOB to conduct inspections of independent registered public accounting firms operating in China makes it more difficult to evaluate the effectiveness of our auditor’s audit procedures or quality control procedures, and to the extent that such inspections might have facilitated improvements in our auditor’s audit procedures and quality control procedures, investors may be deprived of such benefits.

Restrictions on currency exchange under Chinese laws may limit our ability to convert cash derived from our operating activities into foreign currencies and may materially and adversely affect the value of your investment.

Substantially all of our revenues and operating expenses are denominated in Renminbi. Under the relevant foreign exchange restrictions in China, conversion of the Renminbi is permitted, without the need for SAFE approval, for “current account” transactions, which includes dividends, trade, and service-related foreign exchange transactions. Conversion of the Renminbi for “capital account” transactions, which includes foreign direct investment and loans, is still subject to significant limitations and requires approvals from and registration with SAFE and other Chinese regulatory authorities. We cannot assure you that SAFE or other Chinese governmental authorities will not further limit, or eliminate, our ability to purchase foreign currencies in the future. Any existing and future restrictions on currency exchange in China may limit our ability to convert cash derived from our operating activities into foreign currencies to fund expenditures denominated in foreign currencies. If the foreign exchange restrictions in China prevent us from obtaining U.S. dollars or other foreign currencies as required, we may not be able to pay dividends in U.S. dollars or other foreign currencies to our shareholders, including holders of our ADSs. Furthermore, foreign exchange control in respect of the capital account transactions could affect our Chinese subsidiaries’ ability to obtain foreign exchange or conversion into RMB through debt or equity financing, including by means of loans or capital contributions from us.

We face risks related to health epidemics and other outbreaks.

Our business could be adversely affected by the effects of swine flu, avian flu, Severe Acute Respiratory Syndrome, or SARS or other epidemics or outbreaks. China reported a number of cases of SARS in April 2004. In 2006, 2007 and 2008, there were reports on the occurrences of avian flu in various parts of China, including a few confirmed human cases and deaths. In April 2009, an outbreak of swine flu occurred in Mexico and the United States and human cases of swine flu were discovered in China and Hong Kong. In April 2013, there were reports on the occurrences of avian flu in various parts of China, including a number of confirmed human cases and deaths. Any prolonged occurrence or recurrence of swine flu, avian flu, SARS or other adverse public health developments in China or any of the major markets in which we do business may have a material adverse effect on our business and operations. These could include our ability to deliver our products within or outside of China, as well as temporary closure of our manufacturing facilities, or our customers’ facilities, leading to delayed or cancelled orders. Any severe travel or shipment restrictions and closures would severely disrupt our operations and adversely affect our business and results of operations.

Risks Relating to Our ADSs

The trading prices of our ADSs are likelyhave been and may continue to be volatile, which could result in substantial losses to investors.

The closing trading prices of our ADSs ranged from $9.99$3.70 to $14.61$20.05 in 20102012, as retroactively adjusted to reflect the ADS to ordinary share ratio change that took effect on December 21, 2012, and are likely to remain volatile in the future and could fluctuate widely due to factors beyond our control. This may happen because of broad market and industry factors, like the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in the United States. A number of China-based companies, including many solar energy companies, have listed or are in the process of listing their securities on U.S. stock market.exchanges. The securities of some of these companies have experienced significant volatility, including price declines in connection with their initial public offerings. The trading performances of these Chinese companies’ securities after their offerings may affect the attitudes of investors toward Chinese companies listed in the United States in general and consequently may impact the trading performance of our ADSs, regardless of our actual operating performance.

In addition to market and industry factors, the price and trading volume for our ADSs may be highly volatile for factors specific to our own operations, including the following:

Any of these factors may result in large and sudden changes in the volume and price at which our ADSs will trade. We cannot assure you that these factors will not occur in the future.

The sale or availability for sale of substantial amounts of our ADSs could adversely affect their market price.

Sales of substantial amounts of our ADSs in the public market or the perception that these sales could occur, could adversely affect the market price of our ADSs and could materially impair our ability to raise capital through equity offerings in the future. Our ADSs are freely tradable without restriction or further registration under the U.S. Securities Act of 1933, as amended, or the Securities Act, subject to the restrictions in Rule 144 and Rule 701 under the Securities Act and the applicable lock-up agreements.Act. In addition, market sales of securities held by our significant shareholders or any other shareholder or the availability of these securities for future sale may adversely affect the market price of our ADSs.

Our Third Amended and Restated Memorandum and Articles of Association contain anti-takeover provisions that could have a material adverse effect on the rights of holders of our ordinary shares and ADSs.

Our Third Amended and Restated Memorandum and Articles of Association contain provisions to limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction.

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are incorporated under Cayman Islands law.

We are an exempted company incorporated under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, as amended from time to time, the Companies Law of the Cayman Islands (2010(2012 Revision) and the common law of the Cayman Islands. The rights of shareholders to take actions against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

The Cayman Islands courts are also unlikely:

There is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will in certain circumstances recognize and enforce a non-penal judgment of a foreign court of competent jurisdiction without retrial on the merits.

As a result of all of the above, public shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States.

Certain judgments obtained against us by our shareholders may not be enforceable.

We are a Cayman Islands company and all of our assets are located outside of the United States. Substantially all of our current operations are conducted in the China. In addition, a majority of our current directors and officers are nationals and residents of countries other than the United States. Substantially all of the assets of these persons are located outside the United States. As a result, it may be difficult or impossible for you to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the United States federal securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers.

The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to vote your ordinary shares.

As a holder of our ADSs, you will only be able to exercise the voting rights with respect to the underlying ordinary shares in accordance with the provisions of the deposit agreement. Under the deposit agreement, you must vote by giving voting instructions to the depositary. Upon receipt of your voting instructions, the depositary will vote the underlying ordinary shares in accordance with these instructions. You will not be able to directly exercise your right to vote with respect to the underlying shares unless you withdraw the shares. Under our Third Amended and Restated Memorandum and Articles of Association, the minimum notice period required for convening a general meeting is seven days. When a general meeting is convened, you may not receive sufficient advance notice to withdraw the shares underlying your ADSs to allow you to vote with respect to any specific matter. If we ask for your instructions, the depositary will notify you of the upcoming vote and will arrange to deliver our voting materials to you. We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to vote and you may have no legal remedy if the shares underlying your ADSs are not voted as you requested.

The depositary for our ADSs will give us a discretionary proxy to vote our ordinary shares underlying your ADSs if you do not vote at shareholders’ meetings, except in limited circumstances, which could adversely affect your interests.

Under the deposit agreement for the ADSs, if you do not vote, the depositary will give us a discretionary proxy to vote our ordinary shares underlying your ADSs at shareholders’ meetings unless:

The effect of this discretionary proxy is that if you do not vote at shareholders’ meetings, you cannot prevent our ordinary shares underlying your ADSs from being voted, except under the circumstances described above. This may make it more difficult for shareholders to influence the management of our company. Holders of our ordinary shares are not subject to this discretionary proxy.

You may not receive dividends or other distributions on our ordinary shares and you may not receive any value for them, if it is illegal or impractical to make them available to you.

The depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on ordinary shares underlying our ADSs, after deducting its fees and expenses. You will receive these distributions in proportion to the number of ordinary shares your ADSs represent. However, the depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any holders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSs if it consists of securities that require registration under the Securities Act but that are not properly registered or distributed under an applicable exemption from registration. The depositary may also determine that it is not feasible to distribute certain property through the mail. Additionally, the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may determine not to distribute such property. We have no obligation to register under U.S. securities laws any ADSs, ordinary shares, rights or other securities received through such distributions. We also have no obligation to take any other action to permit the distribution of ADSs, ordinary shares, rights or anything else to holders of ADSs. This means that you may not receive distributions we make on our ordinary shares or any value for them if it is illegal or impractical for us to make them available to you. These restrictions may cause a material decline in the value of our ADSs.

You may not be able to participate in rights offerings and may experience dilution of your holdings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. The depositary may, but is not required to, attempt to sell these undistributed rights to third parities,parties, and may allow the rights to lapse. We may be unable to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to endeavor to have a registration statement declared effective. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

You may be subject to limitations on transfer of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of reasons, including in connection with corporate events such as a rights offering, during which time the depositary needs to maintain an exact number of ADS holders on its books for a specified period. The depositary may also close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of our ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

The Company may be classified as a passive foreign investment company or PFIC, for U.S. federal income tax purposes, which could subject U.S. investors in our ADSs or ordinary shares to adverse tax consequences.

A non-United States corporation, such as our company, will be classified as a “passive foreign investment company” (or a “PFIC”), for United States federal income tax purposes, for any taxable year if either (i) 75% or more of its gross income consists of certain types of “passive” income or (ii) 50% or more of the value of its assets (determined on the basis of a quarterly average) produce or are held for the production of passive income. Based on the price of our ADSs and ordinary shares and the composition of our income and assets, weWe do not believe that we were a PFIC, for United States federal income tax purposes, for the taxable year ended

December 31, 2010.2012. Although we do not currently expect that our assets or activities will change in a manner that would cause us to become a PFIC for our current taxable year or the foreseeable future, there can be no assurance our business plans will not change in a manner that will affect our PFIC status. In addition, because the value of our assets for purposes of the PFIC test will generally be determined by reference to the market price of our ADSs and ordinary shares, fluctuations in the market price of our ADSs and ordinary shares may causeincrease the risk of us to becomebecoming a PFIC for the current taxable year or future taxable years.PFIC. Because there are uncertainties in the application of the relevant rules and PFIC status is a fact-intensive determination made on an annual basis, no assurance can be given that we are not or will not become classified as a PFIC.

If we were to be classified as a PFIC in any taxable year, a U.S. Holder (as defined in “Item 10. Additional Information—E. Taxation—Material United States Federal Income Tax Considerations”) may incur significantly increased United States income tax on gain recognized onwould be subject to special rules generally intended to reduce or eliminate any benefits from the sale or other dispositiondeferral of the ADSs or ordinary shares and on the receipt of distributions on the ADSs or ordinary shares to the extent such gain or distribution is treated as an “excess distribution” under the United States federal income tax rules.that a U.S. Holder could derive from investing in a non-United States corporation that does not distribute all of its earnings on a current basis. Further, if we are classified as a PFIC for any year during which a U.S. Holder holds our ADSs or ordinary shares, we generally will continue to be treated as a PFIC for all succeeding years during which such U.S. Holder holds our ADSs or ordinary shares. See “Item 10. Additional Information—E. “Taxation—Material United States Federal Income Tax Considerations—Passive Foreign Investment Company Considerations.”

A. History and Development of the CompanyITEM 4. INFORMATION ON THE COMPANY

Our company was incorporated in Cayman Islands as Mega Stand International Limited in November 2007. We changed our corporate name to Daqo New Energy Corp., or Daqo Cayman, in August 2009.

In January 2008, we established Chongqing Daqo New Energy Co., Ltd., or Chongqing Daqo as our wholly owned operating subsidiary in China. Through Chongqing Daqo, we focus primarily on the manufacture and sale of polysilicon and have recently expanded into the wafer manufacturing. In addition to Chongqing Daqo, we established Nanjing Daqo New Energy Co., Ltd., or Nanjing Daqo, in December 2007 in China, through which we conductconducted our module manufacturing business. In January 2009, we established our wholly owned subsidiary Daqo Solar Energy North America, or Daqo North America, in California as our wholly owned subsidiary to serve as our marketing office to promote our products in North America. In February 2011, we established a wholly owned subsidiary, Daqo New Energy Holdings (Canada) Ltd., or Daqo Canada, to expand our operations in Canada. In 2011, to expand our polysilicon manufacture capacities, we established another wholly owned subsidiary in China named Xinjiang Daqo New Energy Co., Ltd., or Xinjiang Daqo, in China as our wholly owned subsidiary to expand our polysilicon manufacture capacities.

Daqo Group established Daqo New Material on November 16,in 2006 in China. Daqo Group is one of the largest electrical equipment manufacturers in China. Although all of Daqo Group’s equity interest holders also beneficially own shares of Daqo Cayman, Daqo Group does not have any shareholding in our company. As of the date of this annual report, holders of equity interests in Daqo Group in aggregate beneficially own 56.9%57.84% of the outstanding ordinary shares of our company. Daqo New Material’s activities included acquiring land use rights and constructing certain production infrastructure prior to the incorporation of our company and Chongqing Daqo. Subsequent to the establishment of Chongqing Daqo, in July 2008, Chongqing Daqo entered into a lease agreement with Daqo New Material, which was amended and restated in August 2009 with retrospective effect from January 1, 2009, to rent Daqo New Material’s land, production infrastructure, machinery and equipment for its polysilicon production. The initial lease agreement has a five-year term starting from July 1, 2008, with monthly lease payment at a fixed amount. The lease agreement was amended and restated in August 2009, with retrospective effect from January 1, 2009.production of Phase 1a. Under the amended and restated lease agreement, the lease period is from January 1, 2009 to December 31, 2013, with a monthly lease payment at a fixed amount. One month before the expiry of the lease period, Chongqing Daqo has the option to renew the lease on the same terms and conditions for an additional five-year periods.period. Furthermore, the amended and restated lease agreement provides that Chongqing Daqo has the option to purchase, or to designate any person to purchase, the leased assets at the then fair value at any time during the lease period or within one year following the lease period, if permitted by the

PRC laws and regulations. Under current PRC laws and regulations, Chongqing Daqo needs to obtain governmental approval in China to proceed with the purchase, and given the application requirements we do not think it is currently practical for us to obtain such approval. If Daqo New Material desires to transfer the ownership of the leased assets to a third party, Chongqing Daqo has the right of first refusal to acquire the leased assets under the same conditions, and if the leased assets are transferred to a third party, the lease agreement will remain effective and enforceable against the new owner until its expiry. Under Financial Accounting Standards Board Accounting Standards Codification 810-10-15, “Variable Interest Entities,” we are deemed to be Daqo New Material’s primary beneficiary for accounting purposes and Daqo New Material is consideredas a “variable interest entity” of ourshas been consolidated starting from July 1, 2008. Therefore, we have consolidated the financial results of Daqo New Material into our financial statements since July 1, 2008. As of December 31, 2010,2012, Daqo Group’s equity interest in Daqo New Material amounted to $132.9$138.8 million, which was consolidated and reflected as a noncontrolling interest in the balance sheet of our company pursuant to U.S. GAAP. Even though we do not directly or indirectly hold any equity interests in Daqo New Material, under U.S. GAAP, Daqo New Material has been deemed to be our predecessor business from November 16, 2006 through June 30, 2008.

On November 9, 2009, Chongqing Daqo signed a supplemental lease agreement with Daqo New Material to lease the production facilities of Phase 1b from November 9, 2009 until December 31, 2013 at a fixed amount. The other terms of the supplemental lease agreement are the same as those of the amended and restated lease agreement of Phase 1a.

Under a non-competition agreement with us, Daqo Group has agreed not to engage in the business of manufacturing, marketing or distributing polysilicon or any other solar power products anywhere in the world or compete in any manner with our businesses without our consent for an indefinite term. With the approval of our audit committee, we consented for Daqo Group to engage in the photovoltaic cell manufacturing business in China. Daqo Group is in the process of constructing manufacturing facilities and is expected to start commercial production in May 2011. Such related party transactions will beare subject to our audit committee’s review and approval. Under the non-competition agreement, we, through Daqo Cayman and Chongqing Daqo, are entitled to seek temporary restraining orders, injunctions or other equitable relief, in addition to monetary remedies specified in the agreement, if Daqo Group breaches its non-competition obligations. With the approval of our audit committee, we gave our consent to Daqo Group to enter the photovoltaic cell manufacturing business in China. Daqo Group incorporated the wholly owned subsidiary, Zhenjiang Daqo Solar Co., Ltd., or Zhenjiang Daqo, which started commercial production of photovoltaic cell in 2011.

On October 7, 2010, we listed our ADSs, each representing five ordinary shares of Daqo New Energy Corp., on the New York Stock Exchange under the symbol “DQ” in connection with an initial public offering. We issued a total of 9,200,000 ADSs at $9.50 per ADS in connection with our initial public offering.

In February 2011, we incorporated a wholly owned subsidiary, Xinjiang Daqo, in Shihezi Economic Development Area in Xinjiang Autonomous Region, China, to build our Phase 2 polysilicon production facilities. CommercialWe finished construction of our Phase 2 polysilicon facilities in September 2012 and have started pilot production at these facilities is expected to commence in the fourth quarter of 2012.

facilities.

In April 2011, we incorporated a wholly owned subsidiary, Daqo New Energy Holdings (Canada) Ltd., or Daqo Canada.Canada, to expand our operations in North America. Through Daqo Canada, we will set up a joint venture with JNE Solar Inc., a party unrelated to us prior to this transaction, in Hamilton, Ontario,Ontario. This joint venture was terminated in April 2012. Currently, Daqo Canada does not have any material operation, assets or liabilities.

In September 2012, we sold 100% equity interests of our module business to buildDaqo Group for a solar module production facility withconsideration of $9.9 million. On December 21, 2012, we effected a capacitychange of the ADS to ordinary share ratio from one ADS representing five ordinary shares to one ADS representing 25 megawatts of photovoltaic modules. Commercial production at this facility is expected to commence inordinary shares. The ratio change has the fourth quarter of 2011.

We completed an initial public offering of 9,200,000 ADSs in October 2010. On October 7, 2010, we listed our ADSs on the New York Stock Exchange under the symbol “DQ.”

B. Business Overview

Photovoltaics is one of the proven and most rapidly growing renewable energy sources in the world. Energy from the sun is converted into electricity primarily through the photovoltaic effect and, to a lesser extent, through concentrated solar thermal technologies.

We are a leading polysilicon manufacturer based in China and we aim to become a vertically integrated photovoltaic product manufacturer. With an installed annual polysilicon production capacity of 4,300 MT as of December 31, 2010, we believe we are one of the largest polysilicon manufacturers in China. We have started expandingexpanded to the downstream into thephotovoltaic manufacturing businesses to establish facilities for wafer manufacturing. Our current wafer manufacturing business and are ramping up our module manufacturing business. We also intend to enter intoannual capacity is 125MW. The following diagram illustrates the cell manufacturing business invalue chain for the future.manufacture of crystalline-silicon based photovoltaic products:

We manufacture and sell high-quality polysilicon to photovoltaic product manufacturers, who further process our polysilicon into ingots, wafers, cells and modules for solar power solutions. We strive to improve our production efficiency and to increase our output through technological improvements, adoption of process innovation and refinement as well as equipment enhancement. As a result of these initiatives, we produced 3,771 MT of polysilicon in 2010. We plan to increase our annual production capacity to 7,3009,300 MT of polysilicon by the end of 2013 from 4,300 MT in 2012 by adding afully ramping-up commercial production at our Phase 2 production line in Xinjiang and improving our production efficiency.

We believe that we have a competitive cost structure in polysilicon manufacturing primarily The actual production volume may exceed the production capacity due to operational improvements we may implement at our strategic locationfacilities in China and our manufacturing process. As ourresponse to market conditions.

Our current operations are based in Chongqing and Xinjiang, which isare in the western area of China where theChina. The cost of doing business in western China is generally lower than the coastal areas in China,China. Because of our strategic location, we have significantexperience advantages in electricity, raw material and labor costs over our competitors that are based in developed countries or in the coastal areas of China. In addition, weWe utilize the chemical vapor deposition process, or the “modified Siemens process,” to produce polysilicon, as do the vast majority of polysilicon manufacturers in the world. Weand have fully implemented the closed loop system to produce high-quality polysilicon cost-effectively. Our fully implemented closed loop system differentiates us from manufacturers that only implement the closed loop system in some, but not all, of their manufacturing lines, and from manufacturers that are in the process of converting their open loop system to the closed loop system. Compared to the open loop system that many of our China-based competitors use, our closed loop system uses raw materials more efficiently, requires less electricity and causes less pollution even though manufacturingpollution.

In September 2012, we finished construction of our Phase 2 polysilicon facilities based onin Shihezi, Xinjiang Uyghur Autonomous Region. We started pilot production in September 2012 and have successfully reached our targets for both capacity and cost structure by the open loop system can be built within a shorter periodend of time with less initial capital expenditures on equipment. The average unit cost of polysilicon we sold in 2010 was $31.3 per kilogram.March 2013.

We believe that our focus on producing high quality polysilicon in a cost-efficient manner has contributed to our market position. We impose rigorous quality control standards at various stages of our manufacturing process. We systematically test raw materials from our suppliers and test our inputs at each stage of our manufacturing process to ensure that they meet all technical specifications. With our strict quality control measures in our manufacturing and facility construction processes, we are able to produce high-quality polysilicon consistently at both our existing Phase 1 facilities in Chongqing.and Phase 2 facilities. In the fourth quarter of 2010,2012, approximately 99%97.4% of our polysilicon met the solar grade quality standard, approximately 88%94.9% of our polysilicon met the highest specification of the solar grade quality standard, and approximately 65%89.1% of our polysilicon met the electronic grade quality standard in China.

We achieved substantial growth since we commenced commercial production of polysilicon in July 2008, though we experienced a significant downturn in terms of revenue and net income in 2012. We produced 3,771 MT, 4,524 MT and 3,349 MT⁽¹⁾ of polysilicon and sold 3,650, 3,947 MT and 3,262 MT⁽²⁾ in 2010, 2011 and 2012, respectively. We generated revenues from continuing operations of $252.8 million, $232.2 million and $86.9 million in 2010, 2011 and 2012, respectively. We achieved net income attributable to Daqo New Energy Corp. shareholders of $68.6 million and $33.3 million in 2010 and 2011, respectively. We incurred a net loss attributable to Daqo New Energy Corp. shareholders of $111.9 million in 2012.

We currently sell polysilicon to China-based photovoltaic product manufacturers. The majority of our sales, are made under framework contracts. We also sell a significant portion of our polysilicon on a spot pricing basis.contracts, with the prices to be determined at the time when specific sales orders are made.

Industry Background2012.

Photovoltaics is one of the proven and most rapidly growing renewable energy sources in the world. Energy from the sun is converted into electricity primarily through the photovoltaic effect and, to a lesser extent, through concentrated solar thermal technologies.

Distillation. Distillation is a method of separating mixtures based on differences in their boiling points. Raw TCS is purified through distillation to produce high purity TCS feedstock. The difference in boiling points of TCS and impurities such as boron, phosphorous, and metal halides allow for purification of TCS. It is critical to remove these impurities in this process to eliminate the possible causes of low performance in solar cells. The unused HClIn the distillation process, all by-product chemicals from vent gases are separated and TET, a by-product, are also separated from TCS through distillation and condensation. The HCl is recycledfurther purified before being sent back to produce TCS and TET is recycled to produce TCS through hydrogenation.our production areas.

Deposition. The purified TCS from the distillation process is vaporized, mixed with hydrogen gas, and then fed into the deposition reactor. The mixed gas passes over heated silicon slim rods inside the deposition reactor. In the reactor, multiple pair slim rods are heated up to approximately 1,100°C and high purity silicon is deposited on the rods surface. The constant feeding of TCS and hydrogen gas allows for continuous silicon deposition until 150–200mm in diameter is achieved. At this point the deposition cycle is completed and the ultra pure silicon is harvested.

Closed loop manufacturing system

We have implemented the modified Siemens process in a completely closed loop system. The closed loop system is an advanced polysilicon manufacturing process widely used by leading international polysilicon manufacturers. We believe we are one of the few China-based polysilicon manufacturers that have fully implemented the closed loop system in the polysilicon production process. Compared to the open loop system, the closed loop system uses raw materials more efficiently, requires less electricity and produces less pollution. Manufacturing polysilicon generates an exhaust gas primarily consisting of hydrogen, HCl, and chlorosilanes. Using the vent gas recovery system, which combines condensers, distillation towers, adsorption beds and compressors, we are able to recycleseparate the exhaust stream from our manufacturing process into individual components that can be reused.reused after further purification. For instance, a by-product of the deposition step is TET, which is a toxic chemical. Through a separate hydrogenation process, we convert TET to TCS, so that we eliminate the costs related to TET disposal and reduce operational risks of TET treatment. Mixed chlorosilanes are recovered as a liquid stream suitable for separation where we can directly reuse TCS. Anhydrous HCl is recovered with high purity, suitable for use in TCS production. Recovered hydrogen typically contains contaminants of fewer than 10 parts per million and is recycled to the deposition reactors. Recycling significantly reduces costs related to waste disposal and the amount of raw materials we need to purchase for production.

Although the closed loop system has lower manufacturing costs than the open loop system, manufacturing facilities based on the open loop system can be built within a shorter period time with less initial capital investment for equipment. Most of polysilicon manufacturing facilities in China were traditionally built based on the open loop system. However, as the polysilicon market may face downward pricing pressure from time to time, we believe that an increasing number of China-based manufacturers are converting their open loop system to the closed loop system and some of them have completed such conversion. The full implementation of the closed loop system by other polysilicon manufacturers has diminished our competitive advantages provided by this system.

Nevertheless, in August, 2011, Chongqing Daqo entered into a Technology License and Transfer Agreement with GTAT Corporation, a Delaware company, under which, GTAT granted us a license to use its Hydrochlorination TCS Production Technology and Chlorosilane Recovery/Waste Neutralization Technology, which will help expand our manufacturing capacity and significantly reduce electricity consumption to reduce our production cost to reach a more competitive level.

To achieve high efficiency in our manufacturing process, we have also installed a distribution control system and a thermal energy recycling mechanism. The distribution control system enables tight quality control, reduces process related variations, and improves productivity. Our thermal energy recycling system allocates heat generated from our deposition reactors and hydrogenation reactors to many other production areas, such as distillation facilities for TCS purification and our refrigeration station to support a large number of condensers.

Wafers

We have been conductingconducted our wafer business through tolling arrangements with third party wafer manufacturers. We started construction of our Phase 1 250 MW wafer production facilitiesmanufacturers in 2009 and 2010. In July 2010. We2011, we commenced commercial production of mono-crystalline and multi-crystalline silicon wafers in April 2011. We expectat our Phase 1a wafer production facilities, which have a current production capacity of 125 MW. Our in-house wafer production to beis cost competitive due to relatively lower cost of power and labor and our access to high quality polysilicon feedstock and the integration of our polysilicon and wafer operationsproductions at facilities adjacent to each other. We expectbelieve that our in-house wafer operationsproduction will help lower our wafer production costs and produce wafers with consistentimprove quality consistency compared to outsourcing production to third party wafer manufacturers through tolling arrangements. Prior to production capacity ramp-up and full implementation of our wafer expansion plan, we anticipate that we will continue to utilize tolling arrangements to produce a significant portion of our wafers.

The manufacturing process of wafers typically consists of two major steps: ingot preparation and wafering. Multi-crystalline ingots are prepared by directional solidification in a casting furnace, while mono-crystalline ingots are made from single crystal silicon.furnace. Silicon ingots will then be shaped to the required sizes and sliced to wafers by wire saws.

Modules

We produce mono-crystalline and multi-crystalline modules.

To assemble photovoltaic modules, we interconnect multiple photovoltaic cells by soldering and stringing cells into a desired electrical configuration. Cells with similar electrical characteristics are matched during module assembly process to minimize efficiency losses. The interconnected cells are laid out, sandwiched with two layers of polymer, then laminated in a vacuum and cured by heating. The laminated module piece will then be assembled with aluminum frame and connected to a junction box and sent for final testing.

Manufacturing Capacity

The following table sets forth our major installed approximate annual production capacity objectives as of the dates indicated and includes the expected date of initial commercial operation and fully ramped-up production of each expansion phase:

Notes:

We achievedOur annual polysilicon production capacity of 3,300was at 4,300 MT in January 2010 and we increased our production capacity to 4,300 MT by the end of 2010 through capital enhancement projects.2012. We expect to further ramp up our production capacity to 7,3009,300 MT by the end of 2012.

2013.

Our capacity expansion plan is preliminary and subject to risks and uncertainties that may be out of our control. See “Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Our future success depends substantially on our ability to significantly expand our polysilicon production capacity and output, which exposes us to a number of risks and uncertainties” and “Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we are unable to manage our expansion effectively, our business and financial results may be adversely affected.”

Materials and Inputs Used in Production

Polysilicon

Raw materials required for our polysilicon manufacturing process primarily include metallurgical grade silicon, which is silicon of 95% to 99% purity, and liquid chlorine, two widely available industrial raw materials used in our in-house production of TCS, electricity and other utilities, and other significant inputs for production, such as argon gas, caustic soda and graphite parts.

The costs of electricity are significant in the production of polysilicon. The electricity costs in Chongqing are much lower than those in coastal areas in China and those in developed countries due to Chongqing’s abundant hydroelectric resources. The costs of electricity in Xinjiang are even around 50% lower than that in Chongqing due to Xinjiang’s abundant coal resources. We also use other utilities, such as steam, water and natural gas, for our manufacturing process. Steam supply is important to the production of polysilicon. We historically relied uponuse both a local supplier as the sole source of steam forand our production but, since June 2009, we have produced steam in-house capabilities to partially satisfy our steam requirements.

product steam.

Wafers

Wafer manufacturing uses solar grade polysilicon as the primary raw material and consumables such as crucibles, wires and slurry. We intend to utilize our in-house solar grade polysilicon for wafer production. Our high quality polysilicon is a crucial factor that will enable us to provide high quality silicon wafers to customers.

Modules

Raw materials required for the module manufacturing process primarily include high efficiency mono-crystalline and multi-crystalline photovoltaic cells, ethylene-vinyl acetate, tempered glasses, back films, aluminum frames and junction boxes. We intend to continue to utilize tolling arrangements with third party cell manufacturers to exchange our in-house solar grade polysilicon for cells to be further assembled into modules.

high efficiency wafer production.

Equipment

The major polysilicon production equipment includes hydroelectrolysis devices, hydrochlorination synthesis furnaces, TCS synthesis furnaces, distillation towers, polysilicon deposition reactors, hydrogenation reactors, exhaust gas recovery units and distribution control systems. The major wafer production equipment includes crystal growing furnaces, crucible coating machines, squarers, wire saws, wet benches and testing tools. The major module production equipment includes automatic laminating machines, auto framing machines, automatic glue injection machines and testing tools.

We have close relationships with several of the world’s leading equipment manufacturers and work closely with selected equipment manufacturers to develop and build our production lines. In addition, we developed technical specifications for the design of our power supply systems and reactors and have engaged manufacturers

to construct the equipment in accordance with our specifications. Our engineers work closely with our equipment suppliers to design our production facilities. Furthermore, to lower costs, we have purchased and will continue to purchase equipment that can be appropriately designed and manufactured by China-based suppliers. Our technical team is responsible for overseeing the installation of our manufacturing lines to optimize the interaction between the various individual components of the entire production process. They work together with our equipment suppliers’ technical teams on site at the time of installation.

Quality Assurance

We apply our quality control system at each stage of our manufacturing process, from raw materials procurement to production and delivery, in order to ensure a consistent quality of our products. We systematically inspect raw materials from our suppliers, such as MG-Si, liquid chlorine and various consumables for our polysilicon business and photovoltaic cells for our module business. We also test our inputs in each stage of our production process to ensure the inputs meet all technical specifications.

We sample each lot of polysilicon harvested from the deposition reactors and keep the samples for product quality tracking purpose. We also set up a product tracking system to trace back all shipped products to the samples we keep and to our database, which contains detailed information of each shipment. We received the ISO 9001:2000 certification for our quality assurance system for production of polysilicon, which we believe demonstrates our technological capabilities and inspires customer confidence. In addition, in 2009, Chongqing Science and Technology Commission issued a three-year certificate to recognize our polysilicon as a high and new technology product and included our polysilicon in its 2009 list of key new products.product.

We currently conduct much ofFor our wafer business through tolling arrangements with third party wafer manufacturers. In deciding whether to engage in tolling arrangements with a manufacturer,production, we conduct due diligence and evaluate the manufacturer based on several criteria,inspect all critical incoming materials, such as qualificationfeedstock silicon, crucible, slurry and certification, product quality and internal quality assurance standards and procedures. We require third party wafer manufacturerswire to test the technical specifications and quality of each batch of wafers before shipping them toensure they meet our customers. We also conduct in-house quality inspection at our own wafer production facilities.

We inspect and test therequirement. Through manufacturing process, technical parameters such as minority lifetime, resistivity, geometry dimension, surface appearance will be checked at various point of workstation as part of in-process quality of photovoltaic cells sourced from third party cell manufacturers, which are raw materials forcontrol. As final product, each wafer is sent to an automatic inspection machine to be inspected against our module production. Cells that fail to pass our initial inspection are returned to the suppliers. After cells are assembled into modules, we conduct a quality check prior to packaging. Our modules meet international standards for electrical, quality and safety requirements and have been certified by TÜV Rheinland LGA Products GmbH and Underwriters Laboratories Inc. We provide our customers with a five-year limited product warranty against defective materials and workmanship and a 25-year limited power output warranty against loss in power for our modules.

In order to facilitate our production of photovoltaic products and ensure the quality of the finished product, we have set up a laboratoryconduct analysis for the analysis of raw materials, in-process quality controlproducts and finished products and monitor the supervision of environmental pollutionimpact and safety.

safety throughout the production process.

Customers and Sales

We currently sell polysilicon and wafers to China-based photovoltaic product manufacturersmanufacturers. Our polysilicon and modules to photovoltaic system integrators in Europe. Ourwafer customers are mainly China-based photovoltaic companies. Our major customers include operating entities of China Sunergy, Solarfun, Solargiga, Tianwei New Energy and Yingli Green Energy.Energy, Solargiga and Jiangxi Sornid. We sell a substantial portion of our photovoltaic products to a limited number of customers. In 2009, ourOur top three customers in aggregate accounted for 53.6%35.1%, 35.2% and 40.9% of our total revenues. Inrevenues in 2010, our top three customers in aggregate accounted for 35.1% of our total revenues.

2011 and 2012, respectively.

The majority of our polysilicon sales are made under framework contracts. The framework contracts typically provide binding terms for the sales volumes of our polysilicon. The pricing terms are typically agreed

upon between us and our customers based on the prevailing market prices when specific sales orders are made. We also sell a significant portion of our polysilicon products to various China-based customers on a spot pricing basis. We currently sell all of our wafer and module productsproduct on a spot pricing basis.

We have established nationwide marketing capability through our sales team in China. Each member of our sales team is dedicated to a particular region. Our sales team attends domestic and international industrial conferences and trade fairs and organizes advertising and public relations events. Our sales and marketing team works closely with both our research and development team and our production team to coordinate our ongoing supply and demand planning. In addition, to develop our module business internationally, we have recently established a dedicated sales team focused on international sales. Members of this team attend international industrial conferences and trade fairs and pay on-site visits to our potential module customers outside of China.

Research and Development

We believe that the continual development of our technology will be vital to maintaining our long-term competitiveness. Therefore, we intend to significantly increase our investment of management and financial resources in research and development.

We believe that we have one of the leading research and development teams among photovoltaic productpolysilicon manufacturers in China. Our research and development team consists of 2960 experienced researchers and engineers, including 4 experts who enjoy industry-wide recognition in China and internationally and a full-time technical consultants with extensive industry experience.engineers. Our senior management team spearheads our research and development efforts and sets strategic directions for the advancement of our products and production processes, focusing on efforts to improve product quality, reduce manufacturing costs and broaden our product markets. As a resultIn 2012, we completed 29 research and technology or process improvement projects to enhance our polysilicon and wafer manufacturing processes, and filed 7 patents to State Intellectual Property Office of these effort, we were able to, for example, design and complete a capital improvement project to improve our off-gas recovery system in the Wanzhou Phase 1 polysilicon facility. The end result is increase of our name plate capacity from 3,300MT to 4,300MT.PRC.

Intellectual Property

Our intellectual property is an essential element of our business. We rely on patents, copyrights, trademarks, trade secrets and other intellectual property laws, as well as non-competition and confidentiality agreements with our employees, business partners and others, to protect our intellectual property rights.

As of the date of this annual report, we hold 16 patents and have tenadditional 16 pending patent applications covering different aspects of the polysilicon manufacturing process. We also rely heavily on a combination of proprietary process engineering, trade secrets and employee contractual protections to establish and protect our intellectual property, as we believe that many crucial elements of our production processes involve proprietary know-how, technology or data that are not covered by patents or patent applications, including technical processes, equipment designs, algorithms and procedures. We have taken security measures to protect these elements. All of our research and development personnel have entered into confidentiality and proprietary information agreements with us. These agreements address intellectual property protection issues and require our employees to assign to us all of the inventions, designs and technologies that they develop when primarily utilizing our resources or when performing their duties during their employment.

While we continue to develop and pursue patent protection for our own technologies, we expect to continue to rely onimplementing third party license arrangements on certain key aspects of our operation. Pursuant to a technology license and engineering service agreement between Chongqing Daqo and Poly Engineering dated June 15, 2008, as amended in June 2010, Poly Engineering granted a license to Chongqing Daqo with the exclusive rights to utilize certain know-how related to a modified Siemens process to produce polysilicon in Chongqing Daqo’s facilities. The license is perpetual and irrevocable. The license is exclusive within China, Taiwan, Hong Kong and Macau until December 31, 2011. Poly Engineering and its affiliates are prohibited from directly or indirectly soliciting, entertaining offers from or negotiating with any other parties related to the licensed know-how in

China, Taiwan, Hong Kong and Macau during the exclusive period. Pursuant to the agreement, Chongqing Daqo agreed to pay Poly Engineering a fixed amount of fee in 2008 and the amount equal to a percentage its polysilicon revenues in 2009, 2010 and 2011 for the exclusive right and services fees. All amounts due to Poly Engineering by the end of 2010 have been fully paid. Chongqing Daqo and Poly Engineering also entered into a technical services contract dated June 30, 2008, pursuant to which Poly Engineering agreed to provide certain technical supports to Chongqing Daqo. See also “Item 7. Major Shareholders and Related Party Transaction—Transactions with Daqo Group—Transactions relating to Poly Engineering” for historical agreements among Daqo Group, Daqo New Material and Poly Engineering. For the risks associated with our reliance on certain third-party technologies, see “Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—We rely on third party intellectual property for certain key aspects of our operation, which subjects us to the payment of license fees and potential disruption or delays in the production of our products.”

In August, 2011, Chongqing Daqo entered into a Technology License and Transfer Agreement with GTAT Corporation, a Delaware company, under which, GTAT granted us a license to use its Hydrochlorination TCS Production Technology and Chlorosilane Recovery/Waste Neutralization Technology for our current polysilicon production and future polysilicon production expansions.

Most of our equipment supply contracts with international suppliers include an indemnification provision under which the supplier undertakes to indemnify us against actions, claims, demands, costs, charges, and expenses arising from or incurred by reason of any infringement or alleged infringement of patent, copyright, trade mark or trade name by the use of the equipment provided by the supplier. However, it is unclear whether we will be entitled to such indemnification in the event that we use the equipment supplied by such supplier in conjunction with other equipment not supplied by such supplier. In addition, many of our equipment supply contracts with China-based suppliers do not provide any intellectual property indemnification provisions. See “Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—We may be exposed to infringement or misappropriation claims by third parties, which, if determined adversely to us, could cause us to pay significant damage awards.”

Competition

We face competition in China and in the international market in which we may have sales.

The photovoltaic market is dominated by a few major manufacturers with a large number of small manufacturers competing for the remaining small portion of the market. We face competition mainly from top manufacturers who have succeeded in establishing a strong brand name with solar companies. For our polysilicon and wafer businesses, our major international competitors include Hemlock, Wacker, OCI, REC, MEMC, M.Setek, Green Energy Technology, and Sino-American Silicon, and our China-based competitors include GCL-Poly, Tebian Silicon, China Silicon Corporation, Sichuan Xinguang Silicon Science and Technology, LDK Solar, ReneSola, JinkoSolar and Comtec Solar Systems. In addition, many solar cell and module manufacturers have or have announced the intention of establishing polysilicon production or affiliate relationships with manufacturers of polysilicon, including some of our customers and potential customers. We compete with these in-house capabilities, which could limit our ability to expand our sales. Furthermore, the demand for our polysilicon may be adversely affected by alternative technologies in cell manufacturing. The vast majority of silicon-based photovoltaic cell manufacturers currently use chunk or granular polysilicon. However, alternative technologies are being developed in cell manufacturing. For example, one such technology, thin-film cell production, uses little to no silicon in the production of solar cells. We believe that the solar cells made using thin-film technologies tend to have lower energy conversion efficiency than silicon-based solar cells, even though the cost to manufacture thin-film solar cells is lower than that to manufacture silicon-based cells. Based on our management’s industry knowledge, we do not believe that the energy conversion efficiency rates of thin-film cells are likely to reach those of silicon-based cells in the near future. However, if it does happen, thin-film solar cell development and production may expand significantly, which may restrict the market for silicon-based solar cells and decrease the demand for our polysilicon.

As we continue to expand our module business, we expect to face competition from local and international module manufacturers that are substantially larger than us, including solar energy divisions of large conglomerates such as BP Solar and Sharp Corporation, photovoltaic module manufacturers such as SunPower, Suntech Power, Solarfun and Canadian Solar and integrated photovoltaic product manufacturers such as Yingli Green Energy, SolarWorld and Trina Solar.

We believe that the key competitive factors in the market for photovoltaic products include:

We believe we differentiate ourselves from our competitors and capture market share in the polysilicon markets through our product quality, price and cost competitiveness, and manufacturing technologies and efficiency.

Regulation

This section sets forth a summary of the most significant regulations or requirements that affect our business activities in China and our shareholders’ right to receive dividends and other distributions from us.

China.

Renewable Energy Law and Other Government Directives

China enacted the Renewable Energy Law in February 2005 and amended the law in December 2009. The amended Renewable Energy Law sets forth the national policy to encourage and support the development and use of solar and other renewable energy and its use for on-grid generation. The law also sets forth the national policy to encourage the installation and use of solar technologies in water-heating systems, heating and cooling systems, power generation systems and other energy utilization systems. In addition, the law provides financial incentives, such as national funding, preferential loans and tax preferences for the development of renewable energy projects.

In January 2006, the National Development and Reform Commission issued two implementing rules relating to the Renewable Energy Law that, among other things, provide general policies regarding the pricing of on-grid power generated by solar and other renewable energy.

In May 2006, the Ministry of Finance issued measures providing that the Chinese government shall provide certain government subsidies and financial incentives to support the development of the renewable energy industry, including the solar energy industry.

In August 2006, the Ministry of Construction and the Ministry of Finance also issued guidelines which sought to expand the use of solar energy in residential buildings.

In July 2009, the Ministry of Finance, the Ministry of Science and Technology and the National Energy Bureau jointly issued measures that provide for government subsidies to support the photovoltaic industry.

In September 2009, the NDRC and nine other governmental agencies jointly issued measures aimed at curtailing the perceived over-capacity in certain industry sectors, such as steel, concrete, polysilicon and wind power equipment. Pending the promulgation of more specific regulations, the measures require new projects after the date of the new measures in any of the deemed ���over-capacity“over-capacity industries” to obtain approval from NDRC. The measures also provide that the Chinese government shall support polysilicon manufacturers with large

manufacturing capacities and advanced technologies. As a result, any entity which plans to establish a polysilicon manufacturing facility or to expand its current manufacturing facility in China after the measures were issued must seek pre-approval from NDRC. On January 24, 2011, NDRC issued detailed regulations for the approval of new polysilicon construction projects. These new criteria include the following:

a. Capital requirement: the company’s own capital must be no less than 30% of the new polysilicon plant investment;

b. Production scale: solar polysilicon plants must have an annual capacity greater than 3,000 MT; and

Environmental and Safety Regulations

We use, generate and discharge toxic, volatile or otherwise hazardous chemicals and wastes in our research and development and manufacturing activities. China enacted the Environmental Protection Law effective December 1989. In addition to the Environmental Protection Law, we are subject to a variety of specific laws and regulations in China related to the storage, use and disposal of hazardous materials, including laws and regulations governing water pollution, air pollution, solid waste pollution, noise pollution, hazardous chemicals, pollutant discharge fees and environmental impact appraisals. We are also subject to laws and regulations governing worker safety, work safety permits and occupational disease prevention. Our operation is subject to regulation and periodic monitoring by local environmental protection and work safety authorities.

Status of Our Business in Foreign Investment Industrial Guidance Catalogues

The principal regulation governing foreign ownership of businesses in the photovoltaic industry in China is the Foreign Investment Industrial Guidance Catalogue, which is revised from time to time and was last revised effective as of December 1, 2007. The polysilicon manufacturing business falls into the category of encouraged foreign investment industry under the regulation. Foreign invested companies categorized as “encouraged” are entitled to preferential treatment by the Chinese government, including exemption from tariffs on equipment imported for its own use.

Tax

Chinese Enterprise Income Tax

Under the EIT Law, which became effective on January 1, 2008, enterprises in China are generally subject to a uniform income tax rate of 25%. However, qualified enterprises located in central or western China may enjoy preferential tax rate under a series of national policies adopted to encourage investment in central and western China. Chongqing Daqo qualifies for a special reduced rate of 15% through 2010 pursuant to the policies. Accordingly, Chongqing Daqo is subject to the preferential enterprise income tax rate of 15% in lieu of the 25% uniform national tax rate through 2010. As of the date of this annual report, the Chinese government has not announced if they will renew this special reduced rate of 15%. In December 2009, Chongqing Daqo was qualified as a “Chongqing Municipality High and New Technology Enterprise,” subject to the government’s grant of a formal certificate. This will entitle it to a preferential income tax rate of 15% for three years from the grant date of the certificate and can be renewed for additional three-year terms upon Chongqing Daqo’s application and the government’s approval.

Under the EIT Law, an enterprise established outside of China with its “de facto management bodies” within China may be considered a resident enterprise for Chinese tax purposes and be subject to the enterprise income tax at the rate of 25% on its global income. The implementation rules of the EIT Law provide that the

term “de facto management bodies” refers to management bodies which have material management and control over all aspects of the business, including production, operations, personnel, finance, and assets. It is unclear whether Chinese tax authorities would determine that, notwithstanding our status as the Cayman Islands holding company of our operating business in China, we should be classified as a resident enterprise. Currently, substantially all of our income is already China-source income subject to Chinese taxes. However, a portion of the net proceeds received from our initial public offering were deposited into interest bearing bank accounts.

Under the implementation rules for the EIT Law, dividends, interests, rent, royalties and gains on transfers of property payable by a foreign-invested enterprise in China to its foreign investor who is a non-resident enterprise will be subject to a 10% withholding tax, unless such non-resident enterprise’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced rate of withholding tax. The Cayman Islands, where Daqo Cayman is incorporated, does not have such a tax treaty with China.

Chinese Value Added Tax

Pursuant to the Provisional Regulation of China on VAT, and its implementing rules, all entities and individuals that are engaged in the sale of goods, the provision of repairs and replacement services and the importation of goods in China are generally required to pay value-added tax of 17% of the gross sales proceeds received, less any deductible VAT already paid or borne by the taxpayer. Furthermore, when exporting goods, the exporter is entitled VAT refund, which amount will be a portion of or all of the VAT it has already paid or borne.

Foreign Currency Exchange

Foreign currency exchange in China is primarily governed by two sets of regulations issued in 1996.

Under the Foreign Exchange Administration Rules, the Renminbi is freely convertible for routine current account items, including distribution of dividends, payment of interest, and trade and service-related foreign exchange transactions. However, conversion of Renminbi for most capital account items, such as direct investment, overseas loan, securities investment and repatriation of investment, is still subject to the approval of SAFE.

Under the Regulations of Settlement, Sale and Payment of Foreign Exchange, foreign invested enterprises may only buy, sell and remit foreign currencies at authorized banks and must comply with certain procedural requirements, such as providing valid commercial documents and, in the case of capital account item transactions, obtaining approval from the SAFE. Foreign invested enterprises are also subject to limitations on capital investments outside of China, which include requirements to obtain approvals from the Ministry of Commerce, the National Development and Reform Commission and SAFE.

SAFE Circular No. 75

SAFE Circular No. 75, which became effective as of November 1, 2005, requires Chinese residents, including both legal persons and natural persons, to register with their local SAFE branch before establishing or acquiring control of any company outside of China with assets or equity interests in Chinese companies for the purpose of capital financing. Such a company outside of China is referred to as an “offshore special purpose company.” Chinese residents must also file amendments to their registrations if their offshore companies experience capital variation, such as changes in share capital, share transfers, mergers and acquisitions, long-term equity or debt investments or creation of any security interest over any assets located in China or any other material change in share capital. Failure to comply with the registration procedures may result in restrictions being imposed on the foreign exchange activities of the relevant Chinese entity. See “Item 3. Key Information—D. Risk Factors—Risks Relating to Doing Business in China—Chinese regulations relating to offshore investment activities by Chinese residents may increase the administrative burden we face and may subject our

Chinese resident beneficial owners or employees to personal liabilities, limit our subsidiaries’ ability to increase its registered capital or distribute profits to us, limit our ability to inject capital into our Chinese subsidiaries, or may otherwise expose us to liability under Chinese law.”

C. Organizational StructureRegulations on Employee Stock Options Plans

In February 2012, the SAFE promulgated the Notice on the Administration of Foreign Exchange Matters for Domestic Individuals Participating in the Stock Incentive Plans of Overseas Listed Companies, or the Stock Option Notice. According to the Stock Option Notice, a PRC domestic qualified agent or the PRC subsidiary of such overseas listed company must file an application with the SAFE or its local counterpart on behalf of PRC resident individuals who participate in stock incentive plans of overseas publicly-listed companies to obtain approval for an annual allowance with respect to the purchase of foreign exchange in connection with the stock holding or share option exercises. Our company is an “overseas publicly-listed company,” and therefore, we and participants of our share incentive plan who are PRC individuals are subject to these regulations. As the Stock Option Notice is still relatively new, it is unclear how it will be interpreted and implemented by the relevant government authorities. We plan to submit an application with the SAFE or its local counterpart to register our share incentive plan.

D. Property, Plants and Equipment

We are headquartered in Wanzhou, Chongqing, China, where we own several buildings with an aggregate of approximately 82,239 square meters of office and manufacturing space as of December 31, 2010.2012. We have been granted land use rights to approximately 512,240 square meters of land on which our plants or offices are situated, and such land use rights are usually valid for a period of fifty years starting from the date of grant from the local government. Our Phase 2 production facilities in Xinjiang have an aggregate of approximately 92,340 square meters of office and manufacturing space as of December 31, 2012. In addition, we lease approximately 130 and 3803980 square meters of office space in CaliforniaShanghai.

In September 2012, we sold 100% equity interests of Nanjing Daqo to Daqo Group for a consideration of $9.9 million in order to concentrate on our core businesses of polysilicon and Shanghai, respectively.

wafer productions.

We believe that our existing facilities, together with our facilities under construction, are adequate for our current and foreseeable requirements.

See “Item 5. Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Capital Expenditures” for a discussion of our capital expenditures.

Environmental and Safety Matters

Our manufacturing processes generate noise, waste water, gaseous wastes and other industrial wastes. We believe we are in compliance with all present national and local environmental protection requirements in all material respects and have all the necessary environmental permits to conduct our business in China. We process all our waste water and waste gas through various treatments so that they meet the respective national discharge standard. In addition, most of our solid waste can be reused and does not contain poisonous materials. We have established a pollution control system and installed various types of anti-pollution equipment in our facilities to reduce, treat, and where feasible, recycle the wastes generated in our manufacturing process.

We are required to undergo the acceptance inspections of environmental protection and work safety and obtain approval with relevant governmental authorities before our manufacturing lines commence full production. Our production facilities are subject to various pollution control regulations with respect to noise and air pollution and the disposal of waste and other hazardous materials. We have obtained a pollutant discharge permit, a work safety permit for storage and use of hazardous chemicals and permit for the registration of use of atmospheric pressure containers for the pressure containers we have installed.

Insurance

We maintain various insurance policies to safeguard against risks and unexpected events. We purchased property insurance and project construction insurance policies covering our inventory, equipment, vehicles, facilities, buildings and buildings under construction. These insurance policies cover losses due to fire, explosion and a wide range of human accidents. We also provide social security insurance including pension insurance, unemployment insurance, work related injury insurance and medical insurance for our employees. We do not maintain business interruption insurance or general third-party liability insurance. We also do not have product liability insurance or key-man life insurance. See “Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—we have limited insurance coverage. In particular, we do not have any product liability insurance or business interruption insurance.” We consider our insurance coverage to be in line with that of other manufacturing companies of similar size in China.

A. Operating Results

Overview

We are a leading polysilicon manufacturer based in China and we aim to become a vertically integrated photovoltaic product manufacturer. Withwith an installed annual polysilicon production capacity of 4,3009,300 MT as of the date of this annual report, wereport. We believe we are one of the largest polysilicon manufacturers in China. We have started expandingexpanded to the downstream into thephotovoltaic manufacturing business to establish facilities for wafer manufacturing. Our current wafer manufacturing businessannual capacity is 125MW. We plan to gradually increase the utilization rate of our wafer facilities and are ramping up ourincrease the capacity to 250 MW in 2013. We had 100MW module manufacturing business. We also intendproduction facilities in Nanjing, all of which we sold to enter into the cell manufacturing businessDaqo Group in the future.

We strive to improve our polysilicon production efficiency and to increase our output through technological improvements, adoption of process innovation and refinement, as well as equipment enhancement. As a result of these initiatives, we produced 3,7714,524 MT of polysilicon in 2010.2011. In 2012, our polysilicon output was 3,349 MT⁽¹⁾, which was less than 2011 due to annual maintenance and technology improvement in our Wanzhou facilities and less than normal output in our Xinjiang facilities during the pilot production period in the fourth quarter of 2012. We plan to increase our annual production capacity to 7,3009,300 MT by the end of 2012 through adding a2013 as we fully ramp up the production capacity of our Phase 2 production line and improvingimprove our production efficiency.

We currently sell polysilicon to China-based photovoltaic product manufacturers. The majority of our sales are made under framework contracts. We also sell a significant portion of our polysilicon on a spot pricing basis.contracts, with the prices to be determined at the time when specific sales orders are made. As of December 31, 2010,2012, our major photovoltaic product customers included operating entities of China Sunergy, Solarfun, Solargiga, Tianwei New Energy and Yingli Green Energy.

We aimhave expanded to become a vertically integratedthe downstream photovoltaic product manufacturer. We have started expanding downstream into themanufacturing business to establish facilities for wafer manufacturing business. We completed the construction of ourmanufacturing. Our Phase 11a wafer manufacturing facilities in Chongqing with an annual installed capacity of 250 MW commenced commercial production with 125MW capacity in April 2011 and plan to ramp up to the full capacity by the end ofJuly 2011. We will use our own polysilicon to produce wafers. In addition, we are ramping up our module manufacturing business. We plan to sell module products to photovoltaic system integratorsgradually increase the utilization rate of our wafer facilities and distributors in China and internationally, leveraging our well-recognized “Daqo” brand. We expect this downstream market to grow rapidly. We source cells for our module production through direct purchases and tolling arrangements, and we assemble modules at our own facilities. As ofincrease the date of this annual report, we had an annual module production capacity of 150 MW at our facilities in Nanjing and plan to increase our production capacity to 200250 MW by the third quarter of 2011. We commenced commercial production of modules in May 2010 and shipment to Europe in July 2010. We also intend to enter into the cell manufacturing business in the future.2013.

We have achieved substantial growth since we commenced commercial production of polysilicon in July 2008. In 2009,2008, though we produced 1,523 MTexperienced a significant downturn in terms of polysiliconrevenue and sold 1,498 MT, compared to 291 MT of polysilicon produced and 237 MT soldnet income in 2008.

We generated revenues from continuing operations of $111.2$252.8 million, $232.2 million and $242.7$86.9 million in 2010, 2011 and 2012, respectively. We achieved net income attributable to Daqo New Energy Corp. shareholders of $30.8$68.6 million and $68.6$33.3 million in 20092010 and 2010,2011, respectively. We incurred a net loss attributable to Daqo New Energy Corp. shareholders of $111.9 million in 2012.

Note:

Key Factors Affecting Our Results of Operations

The following are key factors that affect our financial condition and results of operations and are important for understanding our business:

Demand for photovoltaic products

Our business and revenue growth are, in part, dependent on the demand for photovoltaic products. The photovoltaic industry remains at a relatively early stage of development and it is uncertain whether solar energy will be widely adopted. Although demand for photovoltaic products has grown significantly over the past decade, the global economic slowdown and turmoil in the global financial markets especially the European sovereign debt crisis that unfolded in 20082010 and continued in 2009,through 2012, coupled with rapid declines in petroleum and natural gas prices, have made solar energy less cost competitive and less attractive as an alternative source of energy.

Demand for photovoltaic products is driven, in part, by government incentives that make the economic cost of solar power competitive with the cost of traditional and other forms of energy. We believe that the near-term growth of the market for solar energy applications depends in large part on the availability and size of government subsidies and economic incentives. Reduction in or elimination of government subsidies and economic incentives may hinder the growth of this market or result in lower sales prices for solar energy products, which could cause our revenues to decline.

Product prices

The sales prices of our photovoltaic products are volatile and cannot always be predicted with certainty. Our sales prices declined from mid-2008 to the middle of 2010 due to industry-wide excessiveexcess supply but stabilized in the third quarter of 2010 and increased mildlymarginally in the fourth quarter of 2010 due to end market surging demand. In 2011 our sales prices declined rapidly in the fourth quarter primarily due to excess supply in the market. The decline in sales prices continued throughout 2012, and sales price recovered slightly in the first quarter of 2013. The decline in the polysilicon market price had resulted in an approximately 61%7% decrease in our average selling price of polysilicon from 20082010 to 20092011 and a further 18%59.3% decrease from 20092011 to 2010. As a result, our revenues from sales of polysilicon increased moderately from $56.4 million in 2008 to $217.9 million in 2010 despite the significant growth in sales volume to customers from 237 MT in 2008 to 3,650 MT in 2010.2012. Our gross margin from continuing operations decreased from 65.6%42.8% in 20082010 to 37.7%37.6% in 20092011 and 43.8%further decreased to negative 43.1% in 2010. We2012. Although the polysilicon market price appeared to have stabilized in the latter part of 2012 and early 2013, we may continue to face downward price pressure as the global sales prices for photovoltaic products continue to fluctuate over time. We expect that our future financial results will also be affected by prices of our wafers, cells and modules.

wafers.

Product mix

The proportion of our revenues that are generated from the sales of other photovoltaic products, also referred to as product mix, affect our revenues and profitability. We currently generate substantially all of ourIn addition to the revenues generated from sales of polysilicon. In 2009, we generated other revenues from sales of cells that we processed through tolling arrangements with third party cell manufacturers and, in 2010,polysilicon, we also generated revenues from other products. In 2010, we generated revenues from sales of modules and wafers. We processed wafers through tolling arrangements with third party wafer manufacturers. AsIn 2011, we expand our wafer and module businesses, we expect that the absolute dollar amounts and the percentage of ourgenerated revenues generated from sales of these products will increase, whilewafers and modules we produced in our profit margins will decrease due tofacilities. In 2012, we generated revenue from sales of modules for the lower profit marginsfirst three quarters of the year before we sold 100% equity interests of Nanjing Daqo, and we generated revenue from sales of wafers produced in our facilities. For the year ended December 31, 2012, the revenues we generated from the sales of polysilicon and wafer accounts for 84.6% and module products as compared to polysilicon. We expect revenues from module sales to account for an increasing portion15.4% of our total revenues from continuing operations, respectively. The revenue generated by the discontinued module business were included in the future. Sales pricesline item of modules are higher than those of polysilicon and wafers, and we plan to utilize our in-house produced polysilicon and wafers for our module products and sell modules directly to customers.

net loss from discontinued operations.

Our production capacity and utilization

WeIn the near future, we plan to significantly increasecontinue to focus on our production capacity and utilizationcore businesses to meet the long-term growth in demand for photovoltaic products and tofurther improve our economies of scale.operation efficiency, cost structure and products quality by expanding our capacity, adopting new technologies and optimizing the manufacturing processes. For our polysilicon business, we ramped up our Phase 1a facilities to their full annual capacity of 1,500 MT in early 2009 and ramped up production at the Phase 1b facilities to their full annual capacity of 1,800 MT in January 2010. We expanded the aggregate capacity of our Phase 1a and Phase 1b facilities to 4,300 MT through a capital enhancement project in 2010 and expect to increase2011. We reached our current total annual production capacity to 7,300of 9,300 MT byat the end of 2012.the first quarter of 2013 as we fully ramped up the production capacity of our Phase 2 facilities in Xinjiang and as we continued to improve our production efficiency. For our wafer business, wethe Phase 1a wafer manufacturing facilities in Chongqing commenced commercial production in AprilJuly 2011 and reached the current capacity of 125 MW in November 2011. We plan to fully ramp up productiongradually increase the utilization rate of our wafer facilities and increase the capacity to 250 MW by the end of 2011. For our module business, we plan to increase our production capacity from 50 MW as of June 30, 2010 to 200 MW in the third quarter of 2011. We believe that this expansion will help us improve economies of scale in production by reducing the unit cost of our products and our equipment costs while significantly increasing our capital expenditures and depreciation expenses.2013.

Our production costs

Our polysilicon production costs consist primarily of the costs of electricity and other utilities, raw materials, labor and labor. As electricity is the largest component of our polysilicon production costs, we anticipate our

production costs to fluctuate from quarter to quarter correlating with the different seasonable electricity rates that the local power grid charges.depreciation. Daqo Chongqing uses electricity generated from the hydropower station in Chongqing which generates electricity mostly during times of high precipitation, primarily in the second and third quarters of each year. As a result, the electricity costs of Daqo Chongqing are generally lower in the second and third quarters and higher in the first and fourth quarters, whichquarters. As electricity is the largest component of our polysilicon production costs, we anticipate our production costs in turn affectsChongqing to fluctuate from quarter to quarter correlating with the different seasonal electricity rates that the local power grid charges. In our costPhase 2 facilities in Xinjiang, because of revenues.the abundant coal resources in Xinjiang, the electricity rate has historically been consistent throughout the year and much lower than that in Chongqing. Accordingly, we do not anticipate our polysilicon production costs in Xinjiang will be impacted by seasonal fluctuation in a manner consistent with the facility in Chongqing. Our wafer production costs consist primarily of the costs of polysilicon, other raw materials, tolling fees charged by third party wafer manufacturers, labor and depreciation. We believe that as we commence and fully ramp up our in-house wafer production capacity, we will be able to reduce the extent of our reliance on tolling arrangements with third party wafer manufacturers, which in turn will reduce unit cost of our wafers. Our module production costs consist primarily of costs of photovoltaic cells, other raw materials, tolling fees charged by third party cell manufacturers, labor and depreciation. We believe that unit cost of our modules will decrease over time as we develop our in-house module production capability and fully integrate our polysilicon, wafer and module manufacturing businesses. With the completion of construction and the gradual ramp-up of our production facilities, we will seekplan to implement additional measures to reduce our production costs.costs through technology, process and equipment improvement. Effective cost-reduction measures will have a direct impact on our financial condition and results of operations. If we fail to continue to reduce our production costs, our profitability and competitiveness will be adversely affected.

Components of Results of Operations

Revenues

SubstantiallyIn 2010, we generated substantially all of our revenues are derived from the sale of polysilicon. In 2009, we2010, the revenues generated other revenues from sales of cells that we processed through tolling arrangementspolysilicon and in 2010, we also generated other revenues from sales of moduleswafers accounted for 86.2% and wafers. We processed wafers through tolling arrangements with third party wafer manufacturers. We expect revenues from module sales to account for an increasing portion13.8% of our total revenues, inrespectively. In 2011, the future. Sales prices of modules are higher than thoserevenues generated from sales of polysilicon and wafers accounted for 94.3% and 5.7% of our total revenues, respectively. In 2012, the revenues we generated from the sales of polysilicon and wafer accounts for 84.6% and 15.4% of our total revenues from continuing operations, respectively. We plan to utilizecontinue to focus on our in-house produced polysiliconcurrent businesses to further improve the operation efficiency, cost structure and wafers for our module products and sell modules directly to customers.quality.

We commenced polysilicon production in July 2008 and therefore did not have any revenues for the period from our inception in 2006 to June 2008. In 2008, weWe produced 2913,771 MT, 4,524 MT and 3,349 MT⁽¹⁾ of polysilicon and sold 2373,650 MT, 3,947 MT and 3,262 MT⁽²⁾ of polysilicon in 2010, 2011 and 2012, respectively. We used approximately 20.5 MT and 54.9 MT of polysilicon. In 2009, we produced 1,523 MT of polysilicon sold 1,498 MT to our customers and used approximately 16 MT to process cells through our tolling arrangements. Inarrangements in 2010 we produced 3,771 MT of polysilicon, sold 3,650 MT to our customers and used approximately 20.5 MT to process wafers through our tolling arrangements.2011, respectively. We didn’t have such business arrangements in 2012. Our polysilicon selling prices are directly affected by global supply and demand conditions. Due to the global oversupply of polysilicon since late 2008 and the resulting pricing pressure, the average selling price of our polysilicon decreased by 61%7% in 20092011 as compared to that in 2008 while the average selling price of our polysilicon2010 and further decreased by 18%59.3% in 20102012 as compared to that in 2009.2011. The decrease of the polysilicon market price in turn adversely affected our revenues in 2008, 20092010, 2011 and 2010.2012.

We generated revenues of $56.4$252.8 million, $111.2$232.2 million and $242.7$86.9⁽²⁾ million from continuing operations in 2010, 2011 and 2012, respectively. We achieved net income attributable to our shareholders of $21.5 million, $30.8$68.6 million and $68.6$33.3 million in 2008, 20092010 and 2010,2011, respectively. We incurred net loss attributable to our shareholders of $111.9 million in 2012. Our revenues in 2009 included $106.2 million generated from sales of polysilicon and $5.0 million from sales of photovoltaic cells processed from our polysilicon through tolling arrangements. Our revenuescontinuing operations in 2010 include $217.9 million generated from sales of polysilicon, $10.8$34.9 million from sales of wafers processedwafers. In 2011, our revenues from our polysilicon through tolling arrangements and $14.0continuing operations include $218.9 million generated from sales of modules.

polysilicon and $13.2 million generated from sales of wafers. In 2012, our revenues from continuing operations include $73.5 million generated from sales of polysilicon, $10.6 million generated from sales of wafers and $2.8 million from ingot and block manufacturing outsourcing services.

We have entered into framework agreements with some of our customers. These contracts typically contain binding terms related to the sales volumes of our photovoltaic products during the contract period. The pricing terms are typically agreed upon between us and our customers based on the prevailing market prices when specific sales orders are placed. Such pricing determination method has caused, and is expected to continue to cause, fluctuations in our revenues and results of operations. We also sold a significant portion of products at spot market prices.

In 2009,2010, our top three customers, Yingli Green Energy, ReneSola and Solargiga, accounted for approximately 28%, 13% and 12% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 54% of our total revenues. During 2010, our top three customers, Yingli Group, Solargiga and Solarfun, accounted for approximately 13.9%, 12.5% and 8.7% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 35.1% of our total revenues. During 2011, our top three customers, Tianwei New Energy, Hanwha SolarOne and Yingli Green Energy, accounted for approximately 13.0%, 11.2% and 11.0% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 35.2% of our total revenues. In 2012, our top three customers, Yingli Green Energy , Solargiga and Jiangxi Sornid, accounted for approximately 25.0%, 8.6% and 7.3% of our total revenues, respectively, and the three customers in aggregate accounted for approximately 40.9% of our total revenues.

Notes:

Cost of revenues

Our cost of revenues primarily consists of:

Due to our capacity expansion, depreciation in absolute terms has increased significantly and we expect thissignificantly. This trend towill continue asif we further expand our polysilicon production capacity and develop our wafer and module businesses.or conduct technology improvement. We also expect that our total cost of revenues will increase as we increase our sales volume. We expect the cost of revenues as a percentage of total revenues may continue to increase as we undertake our vertical integration initiatives while we expect that such increase will be partially offset.

Operating expenses/income

Our operating expenses include selling, general and administrative expenses and research and development expenses, which are partially offset by other operating income as described below.

Selling, general and administrative expenses

Our selling, general and administrative expenses consist primarily of salaries and benefits for our administrative, finance and sales personnel, packaging and shipping costs, sales-related travel and entertainment expenses, other travel and corporate expenses, depreciation of equipment used for administrative purposes and professional expenses. All costs in connection with start-up activities, including costs incurred prior to commencement of production and corporate formation costs of Daqo Cayman, were expensed as incurred. We expect that the amount of our selling, general and administrative expenses will increase as we expand our polysilicon production capacity, execute our vertical integration strategy, increase our sales efforts, hire additional personnel, and incur professional expenses to support our operations as a listed company in the United States.

Research and development expenses

Our research and development expenses consist primarily of costs of raw materials used in research and development activities, salaries and employee benefits for research and development personnel, and equipment costs relating to the design, development, testing and enhancement of our production process. We expect our research and development expenses to increase significantly in the future as we continue to hire additional research and development personnel and focus on improvement of process technologies for our products, and expand our business beyond polysilicon manufacturing.

Other operating income

Our other operating income reflects government subsidies that we receive from time to time, including financial incentives from Chongqing and Xinjiang local government. Wegovernment.We record government subsidies as other operating income when we receive them. The amount and timing of subsidies cannot be predicted with certainty.

Fixed asset impairment loss

We recognized $34.7 million and $42.8 million impairment loss for the long-lived assets of our wafer facilities in 2011 and 2012 respectively. The impairment loss of long-lived assets of our wafer facilities reflects the impact of year-on-year market challenges that have had an adverse effect on the profit-generating ability of these assets.

Interest income and expense

Our interest income represents interest on our cash balances. Our interest expenses relate primarily to our short-term and long-term borrowings from banks, less capitalized interest expenses to the extent they relate to our capital expenditures.

Taxation

Cayman Islands tax

We are a taxan exempted company incorporated in the Cayman Islands and are not subject to tax in this jurisdiction.

PRC tax

Our Chinese subsidiaries are foreign invested enterprises in China. Under the EIT Law, which became effective on January 1, 2008, the Chinese enterprise income tax rate is 25%. However, qualified enterprises located in central or western China may enjoy preferential tax rate under a series of national policies adopted to encourage investment in central and western China.

Under the EIT Law, an enterprise established outside of China with its “de facto management bodies” within China may be considered a resident enterprise for Chinese tax purposes and be subject to the enterprise income tax at the rate of 25% on its global income. The implementation rules of the EIT Law provide that the term “de facto management bodies” refers to management bodies which have material management and control over all aspects of the business, including production, operations, personnel, finance, and assets. It is unclear whether Chinese tax authorities would determine that, notwithstanding our status as the Cayman Islands holding company of our operating business in China, we should be classified as a resident enterprise. Currently, substantially all of our income is already China-source income subject to Chinese taxes. However, a portion of the net proceeds received from our initial public offering were deposited into interest bearing bank accounts.

Chongqing Daqo, our wholly owned Chinese subsidiary and a foreign-invested enterprise established in the central and western region in China, is entitled to a preferential income tax rate of 15% from the date of its establishment to December 31, 2010. In December 2009, Chongqing Daqo wasis qualified as a “Chongqing Municipality High and New Technology Enterprise,” subject to the government’s grant of a formal certificate. This will entitlewhich entitles it to a preferential income tax rate of 15%. Chongqing Daqo received its first qualification in November 2009 for a three-year period. The status was renewed in November 2012 for addition three years fromtill November 2015 and the grant date of the certificate andstatus can be renewedreapplied for additional three-year terms upon Chongqing Daqo’s application and the government’s approval. Xinjiang Daqo is in the process of applying for “High and New Technology Enterprise” status, which entitles it to enjoy the preferential income tax rate of 15%.

Daqo New Material, our consolidated variable interest entity and a domestic Chinese enterprise, was subject to an income tax rate of 33% for the period from November 16, 2006 to December 31, 2007 and 25% from January 1, 2008 onward.

Nanjing Daqo, our wholly owned Chinese subsidiary and a foreign invested enterprise, is subject to an income tax rate of 25%.

Under the EIT Law and implementation regulations issued by the State Council of China, a dividend paymentdividends, interests, rent, royalties and gains on transfers of property payable by a foreign-invested entityenterprise in China to its foreign shareholdersinvestor who is a non-resident enterprise will be subject to a 10% withholding tax. Wetax, unless such non-resident enterprise’s jurisdiction of incorporation has a tax treaty with China that provides for a reduced rate of withholding tax and such non-resident enterprise is the beneficial owner of the dividends, interests, rent, royalties and gains on transfers of property. The Cayman Islands, where Daqo Cayman is incorporated, does not have such a tax treaty with China. However, we intend to reinvest all of Chongqing Daqo’s undistributed earnings into our capacity expansion and/or technology improvement and do not plan to distribute any of the earnings as dividends in the foreseeable future and, accordingly, we have not set aside provision for Chinese dividend withholding tax. If we do distribute these earnings in the form of dividends, we will be subject to the withholding tax at a rate of 10%.

Pursuant to the Interim Regulations on Value Added Tax and their implementation rules, all entities and individuals that are engaged in the sale of goods, the provision of repairs and replacement services or the importation of goods in China are generally required to pay value-added tax, or VAT, at a rate of 17% of the gross sales proceeds received, less any deductible VAT already paid or borne by the taxpayer. Furthermore, when exporting goods, the exporter is entitled to VAT refund, which amount will be a portion of or all of the VAT that it has already paid or borne. For our sale of polysilicon products to China-based purchasers, we are subject to the 17% VAT without any VAT refunds for such sales.

Critical Accounting Policies

We prepare our consolidated financial statements in accordance with U.S. GAAP, which requires us to make judgments, estimates and assumptions that affect (1) the reported amounts of assets and liabilities, (2) disclosure of contingent assets and liabilities at the end of each reporting period, and (3) the reported amounts of revenues and expenses during each reporting period. We continually evaluate these estimates and assumptions based on historical experience, knowledge and assessment of current business and other conditions, and expectations regarding the future based on available information and reasonable assumptions, which together form a basis for making judgments about matters not readily apparent from other sources. Since the use of estimates is an integral component of the financial reporting process, actual results could differ from those estimates. Some of our accounting policies require higher degrees of judgment than others in their application. When reviewing our financial statements, you should consider (1) our selection of critical accounting policies, (2) the judgment and other uncertainties affecting the application of such policies, and (3) the sensitivity of reported results to changes in conditions and assumptions. We consider the policies discussed below to be critical to an understanding of our financial statements as their application places the most significant demands on the judgment of our management.

Revenue recognition

We generate revenues primarily from the sale of polysilicon wafer and modulewafer and recognize revenues when all of the following conditions are met: persuasive evidence of an arrangement exists, the sales price is fixed and determinable, delivery of the products has occurred, title and risk of loss have transferred to customers and collectability of receivable is reasonably assured. Our polysilicon sales agreements with our customers typically do not contain product warranties except for return and replacement of defective products within a period ranging from 3 to 30 days from delivery. In addition, our agreements do not contain post-shipment obligations or any other return or credit provisions.

A majority of our sales contracts provide that title and risk of loss related to the products are transferred to our customers upon receipt. We may extend credit terms to our customers after assessing a number of factors to determine their credit worthiness.

Allowance for doubtful accounts

We conduct credit reviews for customers to whom we extend credit terms. We estimate the amount of accounts receivable that may not be collected based on the aging of our accounts receivable and specific evidence relating to the financial condition of our customers that may affect their ability to pay their balances.

Depreciation

Our long-lived assets mainly include property, plant and equipment. We depreciate our property, plant and equipment on a straight-line basis over the estimated useful lives of the assets, taking into account the assets’ estimated residual values. We estimate the useful lives and residual values at the time we acquire the assets based on our management’s knowledge on the useful lives of similar assets and replacement costs of similar assets having been used for the same useful lives in the market, and taking into account anticipated technological or other changes. On this basis, we have estimated the useful lives of our buildings and plants to be 20 years, our machinery and equipment to be 10 years, our furniture and office equipment to be 3 to 5 years and our motor vehicles to be 6 years. We review the estimated useful life and residual value for each of our long-lived assets on a regular basis. If technological changes occur more rapidly than anticipated, we may shorten the useful lives or lower the residual value assigned to these assets, which will result in the recognition of increased depreciation and amortization expense in future periods.

Impairment of long-lived assets

We evaluate our long-lived assets and finite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. When these events occur,Factors that we consider in deciding when to perform an impairment review include, but are not limited to significant under-performance of a business or product line in relation to expectations, significant negative industry or economic trends, and significant changes or planed changes in the use of the assets. An impairment analysis is performed at the lowest level of identifiable independent cash flows for an asset or asset group. We make subjective judgments in determining the independent cash flows that can be related to a specific asset group based on the asset usage model and manufacturing capabilities. We measure impairmentthe recoverability of assets that will continue to be used in the operations by comparing the carrying amountvalue of the asset group to the estimate of the related total future undiscounted net cash flows expected to result fromflows. If an asset group’s carrying value is not recoverable through the use of the assets and their eventual disposition. If the sum of the expectedrelated undiscounted cash flows, is less than the carrying amount of the assets, we would recognize an impairment loss equal tois measured by comparing the excess ofdifference between the asset group’s carrying amount overvalue and its fair value. We determine the fair value of the assets. Fair value is based uponan asset or asset group utilizing estimated future discounted cash flows of the assets at the rate deemed reasonableand incorporate assumptions that it believes marketplace participants would utilize. The impairment charges for the type of asset and prevailing market conditions, appraisals and, if appropriate, current estimated net sales proceeds from pending offers. Future cash flow estimates are, by their nature, subjective and actual results may differ materially from our estimates. If our ongoing estimates of future cash flows are not met, we may have to record additional impairment charges in the future accounting periods. Our estimates of cash flows are based on the current regulatory, social and economic climates where we conduct our operations as well as recent operating information and budgets for our business. These estimates could be negatively impacted by changes in laws and regulations, economic downturns, or other events affecting our business. For the periods presented, we recorded no impairment of our long-lived assets.

Product warranties

We provide a limited warranty to the original purchasers of our solar modules for periods of two or five years regarding defects in materials and workmanship, and 25 years regarding minimum power output. We accrue warranty costs when recognizing revenue and recognize such costs as a component of selling expense. Warranty costs primarily consist of replacement costs for parts and materials and labor costs for maintenance personnel. Due to our limited solar module manufacturing history, we have not yet had any warranty claims. Based on our best estimates of both future costs and the probability of incurring warranty claims, we currently accrue for product warranties at 1% of solar module sales. We derive our estimates from a number of factors, including (1) an assessment of competitors’ accrual and claim history and (2) results from academic research, including industry—standard accelerated testing and other assumptions that we believe to be reasonable under the circumstances. We acknowledge that such estimates are subjective and we will continue to analyze the performance of our products compared to our competitors and academic research results to determine whether the accrual is adequate. To the extent that actual warranty costs differ from our estimates, or our expectations of future costs change, we will prospectively revise our accrual rate and/or the accrual balance. Such adjustments could have a material effect on our consolidated results of operations. For example, an increase or decrease of 0.1% accrual rate (i.e., to 1.1% or 0.9%) would have resulted in a corresponding increase or decrease in warranty expenses of $13,984 for the year ended December 31, 2010.

2010, 2011 and 2012 were $nil, $38,512,376 (among which $3,844,799 was included in loss from discontinued operations) and $42,754,481, respectively. The impairment loss incurred in fiscal year 2012 was related to the impairment of long-lived assets of the wafer business, and was triggered primarily by the significant decrease in average selling prices for wafers that was experienced in 2012.

ConsolidationValuation of variable interest entityDeferred Tax Assets

In addition to the financial statements of Chongqing Daqo and Nanjing Daqo, our wholly owned subsidiaries in China, we also consolidated the financial statements of Daqo New Material as a variable interest entity of Chongqing Daqo starting from July 1, 2008.

We were incorporated in November 2007 in the Cayman Islands. Our principal operating subsidiary, Chongqing Daqo, was established in China in January 2008. Daqo New Material was established by Daqo Group, an affiliated company controlled by our founding shareholders, on November 16, 2006. Daqo New Material’s activities included acquiring land use rights for our polysilicon manufacturing and constructing certain production infrastructure prior to the incorporation of our company and Chongqing Daqo.

After its establishment, Chongqing Daqo entered into a lease agreement with Daqo New Material dated June 30, 2008 to rent all of Daqo New Material’s land, production infrastructure and machinery and equipment for our polysilicon production. The initial lease agreement has a five-year term starting July 1, 2008, with monthly lease payments at a fixed amount of RMB9.95 million ($1.4 million). The rental amount under the

initial lease agreement was determined based on factors, such as Daqo New Material’s operating expenses, interest expenses and the return on investment required by Daqo New Material’s owners. The initial lease agreement also provided that if Daqo New Material transferred the ownership of the leased assets to any third party, the lease agreement will remain effective and enforceable against the new owner until its expiry. One month before the expiry of the initial lease term, the lease agreement could be renewed for an additional five- year term upon mutual consent. Chongqing Daqo had the right of first refusal to rent the leased assets under the initial lease agreement.

The lease agreement was amended and restated in August 2009, with retrospective effect from January 1, 2009. After one year of operations, Daqo New Material and Chongqing Daqo concluded that the lease payments under the original lease agreement would result in excessive return on investment to Daqo New Material in the foreseeable future. The amount of the monthly lease payment was thus reduced to RMB6.1 million ($0.9 million) in the amended and restated lease agreement. Under the amended and restated lease agreement, the lease period is from January 1, 2009 until December 31, 2013. One month before the expiry of the lease period, Chongqing Daqo has the option to renew the lease on the same terms and conditions for additional five-year periods. Furthermore, the amended and restated lease agreement provides that Chongqing Daqo has the option to purchase, or to designate any person to purchase, the leased assets at the then fair value at any time during the lease period or within one year following the lease period, if permitted by the PRC laws and regulations. If Daqo New Material desires to transfer the ownership of the leased assets to a third party, Chongqing Daqo has the right of first refusal to acquire the leased assets under the same conditions, and if the leased assets are transferred to a third party, the lease agreement will remain effective and enforceable against the new owner.

On November 9, 2009, Chongqing Daqo entered into a supplemental lease agreement with Daqo New Material to lease the production facilities for Phase 1b from November 9, 2009 until December 31, 2013 at a fixed amount. The other terms of the supplemental lease agreement are the same as those of the amended and restated lease agreement of Phase 1a.

As the aggregate value of the monthly rental payments that Chongqing Daqo is contractually obligated to make to Daqo New Material represents the majority of the value of Daqo New Material’s assets, Daqo Group has less investment risk in Daqo New Material, its wholly owned subsidiary, than does Chongqing Daqo. Under U.S. GAAP, these contractual obligations represent an implicit guarantee between related parties, and Daqo New Material is considered to be our “variable interest entity.” We considered the accounting guidance for variable interest entities and concluded that we have the characteristics of a controlling financial interest. Therefore, Chongqing Daqo is considered the “primary beneficiary” of Daqo New Material. As a result, we have consolidated Daqo New Material’s financial results into our own since July 1, 2008. Even though we do not directly or indirectly hold any equity interests in Daqo New Material, Daqo New Material has been deemed to be our predecessor business from November 16, 2006 through June 30, 2008 under U.S. GAAP.

The assets and liabilities of Daqo New Material are consolidated at historical cost. Daqo Group’s total equity interests in Daqo New Material are presented as a noncontrolling interest on our financial statements. The amount of net income (loss) attributable to noncontrolling interest is equivalent to the rental income that Daqo New Material receives from Chongqing Daqo minus depreciation and interests costs during each reporting period. Please refer to note 15 to our consolidated financial statements included elsewhere in this annual report for details of Daqo New Material’s total assets and liabilities as of December 31, 2010 and its net revenues, operating costs and expenses, net income for the year ended December 31, 2010.

Income taxes

We periodically evaluate the likelihood of the realization of deferred tax assets, and reduce the carrying amount of these deferred tax assets by a valuation allowance to the extent we believe a portion will not be realized. We consider many factors when assessing the likelihood of future realization of our deferred tax assets, including our recent cumulative earnings experience by taxing jurisdiction, expectations of future taxable

income, the carry-forward periods available to us for tax reporting purposes, and other relevant factors. Deferred income taxes are recognized for (1) temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, or (2) net operating loss carry forwards and credits by applying enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws of the relevant taxing authorities. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on the characteristics of the underlying assets and liabilities, or the expected timing of their use when they do not relate to a specific asset or liability.

We recognize a tax benefit associated with an uncertain tax position when, in our judgment, it is more likely than not that A valuation allowance of $37.7 million was established for the position will be sustained upon examination by a taxing authority. For a tax position that meets the more-likely-than-not recognition threshold, we initially and subsequently measure the tax benefit as the largest amount that we judge to have a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority. Our liability associated with unrecognized tax benefits is adjusted periodically due to changing circumstances, such as the progress of tax audits, case law developments and new or emerging legislation. Such adjustments are recognized entirely in the period in which they are identified. Our effective tax rate includes the net impact of changes in the liability for unrecognized tax benefits and subsequent adjustments as considered appropriate by management. We classify interest and penalties recognized on the liability for unrecognized tax benefits as income tax expense.

Valuation of inventories

Our inventories are stated at the lower of cost or net realizable value. The valuation of inventory involves our management’s determination of the value of excess and slow moving inventory, which is based upon assumptions of future demands and market conditions. If actual market conditions are less favorable than those projected by management, inventory write-downs may be required. We routinely evaluate quantities and value of our inventories in light of current market conditions and market trends, and record write-downs against the cost of inventories for a decline in net realizable value. Inventory write-down charges establish a new cost basis for inventory. In estimating obsolescence, we utilize our backlog information and project future demand. Market conditions are subject to change and actual consumption of inventories could differ from forecasted demand. Furthermore, the price of polysilicon is subject to fluctuations based on global supply and demand. If actual market conditions are less favorable or other factors arise that are significantly different than those anticipated by our management, additional inventory write-downs or increases in obsolescence reserves may be required. Our management continually monitors the spot price of polysilicon to ensure that inventory is recorded at the lower of cost or net realizable value.

Share-based compensation expenses

On October 31, 2009, we granted options to purchase a total of 5,350,000 ordinary shares to our officers, directors, employees and consultants pursuant to our 2009 share incentive plan. The original exercise price of all of the options iswas $1.38 per share.share, which was re-priced to $0.25 per share on April 3, 2013 with the approval of our board of directors. Twenty-five percent of the ordinary shares subject to the options will vest one year following the grant date, and the remaining seventy-five percent of the ordinary shares subject to the option will vest in 36 equal monthly installments over the next three years. We did not grant any options or other equity incentives to any officer, director, employee or consultant before October 2009.

On October 6, 2010, we granted options to acquire 120,000 ordinary shares to independent directors pursuant to the Option Plan. Thirty percent (30%) of the ordinary shares subject to the Option Plan will vest one year following the grant date, thirty percent (30%) of the ordinary shares subject to the Option Plan will vest on the second year anniversary of the grant date, and the remaining forty percent (40%) of the ordinary shares subject to the Option Plan will vest on the third year anniversary of the grant date. These options were granted in anticipation of services to be provided during the respective service periods. The original exercise price is $1.90.of these options was $1.90 per share which was re-priced to $0.25 per share on April 3, 2013.

On December 3, 2010, we granted options to acquire 2,190,000 ordinary shares to certain officers, directors and employees pursuant to the Option Plan. The ordinary shares subject to the Option Plan will vest in four equal annual installments, with the first installment vesting one year following the grant date. These options were granted in anticipation of services to be provided during the respective service periods. The original exercise price of these options was $2.35 per share which was re-priced to $0.25 per share on April 3, 2013.

On January 9, 2012, we granted options to acquire 1,190,000 ordinary shares to certain independent directors, officers and employees pursuant to the Option Plan. For the independent directors, thirty percent (30%) of the ordinary shares subject to the Option Plan will vest one year following the grant date, thirty percent (30%) of the ordinary shares subject to the Option Plan will vest on the second year anniversary of the grant date, and the remaining forty percent (40%) of the ordinary shares subject to the Option Plan will vest on the third year anniversary of the grant date. For the officers and employees, twenty-five percent (25%) of the ordinary shares subject to the options will vest one year following the grant date, and the remaining seventy-five percent (75%) of the ordinary shares subject to the option will vest in 36 equal monthly installments over the next three years. These options were granted in anticipation of services to be provided during the respective service periods. The original exercise price was $0.42 per share, which was re-priced to $0.25 per share on April 3, 2013.

On April 3, 2013, we granted options to acquire 140,000 ordinary shares to a certain independent director pursuant to the Option Plan. The exercise price is $2.35.$0.25 per share. Thirty percent (30%) of the ordinary shares subject to the Option Plan will vest as of 24 December 2013, another thirty percent (30%) will vest as of 24 December 2014, and the remaining forty percent (40%) will vest as of 24 December 2015. These options were granted in anticipation of services to be provided during the respective service periods. The exercise price is $0.25 per share.

As of the end of 2012, a total number of 1,670,500 options have been forfeited due to grantees’ departure from the company.

We recognize share-based compensation in the statement of operations based on the fair value of equity awards on the date of the grant, with compensation expense recognized over the period in which the grantee is required to provide service to us in exchange for the equity award. We have made an estimate of expected forfeiture and is recognizing compensation costs only for those equity awards to vest. The share-based compensation expenses have been classified as either selling, general and administrative expenses or research and development expenses, depending on the job functions of the grantees.

With respect to options granted on October 31, 2009 when we were a private company, we determined the fair value of our ordinary shares with the assistance of an independent appraiser. Determining the fair value of options and ordinary shares requires making complex and subjective judgments regarding projected financial and operating results, our unique business risks, the liquidity of our shares and our operating history and prospectus at the time of grant. In estimating the fair value of ordinary shares, we used income approach and the market approach as a cross check. The market approach incorporates certain assumptions including the market performance of comparable listed companies, as well as our forecasted financial results and growth trends. The income approach involved applying appropriate discount rates to discount cash flows that were based on our earnings forecasts. Other major assumptions used in determining the fair value of ordinary shares include weighted average costs of capital and discount for lack of marketability. We also used other general assumptions, including: no material changes in existing political, legal, fiscal and economic conditions and polysilicon industry in China; our ability to retain competent management and key personnel to support our ongoing operations; and no material deviation in market conditions from economic forecasts.

We estimated the fair value of the options granted on October 31, 2009 using the Black-Scholes option pricing model with the assistance of the independent appraiser. As we did not have historical share option exercise experience, the expected term was estimated as the average between the vesting term of the options and the original contractual term. The volatility of the underlying ordinary shares during the life of the options was estimated based on the historical stock price volatility of listed comparable companies over a period comparable to the expected term of the options. The risk-free interest rate was estimated based on the yield to maturity of China international government bonds with a maturity period close to the expected term of the options. The dividend yield was estimated based on the expected dividend policy over the expected term of the options.

With respect to options granted on October 6, 2010 and December 3, 2010, we estimated the fair value of share options granted using the Binomial option pricing model with the assistance of the independent appraiser, which requires the input of highly subjective assumptions, including the expected life of the share options, estimated forfeitures and the price volatility of the underlying shares. The assumptions used in calculating the fair value of share options represent management’s best estimates. As a result, if factors change and we use different assumptions, our share-based compensation expense could be materially different in the future. In addition, we estimate our expected forfeiture rate and recognize the expense only for those shares expected to vest. These estimates are based on past employee-retention rates. We will prospectively revise our estimated forfeiture rates based on actual history. Our compensation expense may change based on changes to our actual forfeitures of these share options.

Internal Control Over Financial Reporting

PriorWith respect to options granted on January 9, 2012, we estimated the fair value of share options granted using the Binomial option pricing model with the assistance of the independent appraiser, which requires the input of highly subjective assumptions, including the expected life of the share options, estimated forfeitures and the price volatility of the underlying shares. The assumptions used in calculating the fair value of share options represent management’s best estimates. As a result, if factors change and we use different assumptions, our share-based compensation expense could be materially different in the future. In addition, we estimate our expected forfeiture rate and recognize the expense only for those shares expected to vest. These estimates are based on past employee-retention rates. We will prospectively revise our estimated forfeiture rates based on actual history. Our compensation expense may change based on changes to our initial public offering, we were a private company with limited accounting personnel and other resources with which to address our internal controls over financial reporting. Our independent registered public accounting firm has not conducted an auditactual forfeitures of our internal control over financial reporting. However, inthese share options.

connection with the audits of our consolidated financial statements as of and for the years ended December 31, 2009 and 2010, we and our independent registered public accounting firm identified one “material weakness” and one “significant deficiency” in our internal control over financial reporting, as defined in the standards established by the Public Company Accounting Oversight Board of the United States. The material weakness identified related to our lack of sufficient accounting resources and expertise necessary to comply with U.S. GAAP and SEC reporting and compliance requirements. The significant deficiency identified related to our lack of sufficient and formally documented procedures for the financial closing and reporting process.

In compliance with Section 404 and its applicable rules and regulations, we have taken certain steps to remedy the material weakness and the significant deficiency, including hiring an outside consulting firm to review our internal control processes, policies and procedures in order to assist us in identifying any weaknesses or deficiencies in our internal control over financial reporting.

We will continue to implement measures during 2011 to remedy the material weakness and the significant deficiency, including:

We are working to implement these measures, although we cannot assure you that we will complete such implementation in a timely manner.
