Greater-than-expected solar power demand to drive up polysilicon prices

In 2011, solar power demand is anticipated to exceed the market consensus forecast. In the aftermath of the earthquake in Japan, major European nations and the U.S. are likely to maintain generous subsidies for the solar power industry. With Buy (Initiate) a drop in installation costs, generous subsidies would result in a higher internal rate Target Price (12M, W) 670,000 of return, which would drive demand, as in 2010.

I. Valuation

1. Valuation of polysilicon business using a target EV/EBITDA of 8x

Target EV/EBITDA: 10% We derived our target price for OCI (W670,000) by applying respective target EV/EBITDA premium to multiple of multiples for all of the companyÊs business divisions to the respective averages of their chemicals sector; 10% 2011F~2013F EBITDAs. We used 2011F~2013F EBITDA numbers to reflect the significant discount to multiple of growth momentum from the companyÊs large-scale polysilicon capacity expansion. Our electronic materials target price, which is equivalent to a 2011F P/E of 15x and a P/B of 5.0x, appears reasonable, sector considering the companyÊs 2011F ROE of 40.1% and its mid- to long-term growth prospects.

The value of OCIÊs polysilicon business was derived using a target EV/EBITDA multiple of 8x. Our target EV/EBITDA multiple is equivalent to a 10% premium to the EV/EBITDA of the chemicals sector and a 10% discount to the EV/EBITDA of the electronic materials sector. The 10% premium to the multiple for the chemicals sector reflects the fact that the polysilicon business has high growth potential and high barriers to entry compared to other chemical segments; and the 10% discount to the multiple for the electronic materials sector reflects the expected intense market competition after 2013.

Our higher-than-peer- Our target EV/EBITDA of 8x for OCI is 20% higher than that of global polysilicon makers (6x). average EV/EBITDA However, we believe that this premium is justifiable, considering: 1) OCIÊs peers are appears reasonable engaging in low value-added businesses (e.g., cells and modules), and 2) OCI is expected to remain the market leader even amid intense competition after 2013.

1) Polysilicon: Core raw material for solar cells Polysilicon is a key component of solar panel construction. Polysilicon is used to make silicon wafers, which are then turned into solar cells after a variety of processes.

Cost and quality are key Polysilicon accounts for 28% of solar cell manufacturing costs. Since the purity of polysilicon determines the solar cell conversion efficiency, solar cell manufacturers must secure high- quality polysilicon at low costs.

Polysilicon: Combined Polysilicon is a value-added product with the highest entry barrier in the solar cell supply market share of top six chain. There are many players in the wafer, cell, and module markets, with Chinese makers companies stood at gaining the upper hand thanks to their cost competitiveness. Meanwhile, the polysilicon 78% in 2010 market is dominated by only six companies, including Hamlock and Wacker Chemie, whose combined market share stood at 78% in 2010.

High technological The oligopolistic market structure is attributable to 1) high technological barriers and 2) the barrier; massive amount massive amount of time and money required for building production facilities (two to three of time and money years; more than W1tr needed to build capacity of 10,000 tonnes).

Polysilicon is manufactured by turning 99% silicon into gaseous trichlorosilane or monosilane and inducing the deposition of 6N (99.9999%)~11N (99.999999999%) polysilicon.

Siemens Process is the Polysilicon manufacturing techniques include: 1) metallurgical refining, 2) FBR, and 2) most widely used Siemens Process. Metallurgical refining has become less popular due to lower polysilicon technique for producing prices. FBR, which is heralded for its cost efficiency in comparison to the Siemens Process, polysilicon is only used by a few manufacturers, such as MEMC and REC, due to difficulties related to raising yield. As such, the Siemens Process is currently the most widely used technique.

2) Petro & coal chemicals: Stable growth expected Supply contract changes OCI produces carbon black from by-products, including coal tar and crude light oil, supplied will not slowdown by POSCO. We expect OCIÊs carbon black business to post stable growth on the back of 1) earnings significantly rising demand from the tire and automobile industries and 2) its domestic market dominance. Although recent changes in its raw material supply contract with POSCO will likely lead to higher raw material costs, OCI will be able to display stable earnings in light of high margins at its competitors, in our view.

OCI plans to enhance its market position through investments in the carbon black business, while pursuing new value-added businesses, including VIP (vacuum insulation panel) and needle coke.

3) LED sapphire ingot: Ready to advance into the market on cost savings A market with huge OCI announced its plan to invest US$89.3mn in the LED sapphire ingot market, with a 2013 growth potential and sales target of W55.9bn. high barriers to entry LED sapphire ingot is a raw material for wafers used in LED chips. Currently, the top three makers hold a combined market share of 85% due to high technological entry barriers. OCI expects the LED sapphire ingot market to grow sharply from US$589mn in 2011 to US$1,248 in 2014, in line with the widening application of LEDs (from LED TVs to lighting).

OCI to develop new OCI believes that it can cut production costs markedly by developing a new sapphire ingot sapphire ingot production method (i.e., heat exchange) in partnership with the equipment maker GT Solar. production method in It remains to be seen whether the new method will gain approval and lead to mass partnership with GT production. However, the new method seems highly likely to succeed, given 1) GT SolarÊs Solar superior competitiveness in solar cell-use silicone ingot, and 2) OCI and GT SolarÊs strong track records for developing polysilicone production facilities.

III. Industry outlook

1. Solar cell market outlook

1) Demand growth to exceed expectations; Market to grow to 100GW in 2020 Demand to exceed The global solar cell market is forecast to grow 34% YoY to 21GW (in terms of new expectations in 2011 installations) in 2011. Last year, the market grew 167% YoY to 16GW, far exceeding market expectations. The rapid expansion seems attributable to declining solar cell module prices, and strong installation demand ahead of government cuts to FiTs (Feed-in Tariffs) in 2011.

EuropeÊs subsidy cuts to The solar cell market will likely continue to expand faster than expected in 2011. European be small in the wake of nations are unlikely to cut FiT markedly in the wake of the nuclear crisis in Japan. In the U.S., nuclear issues in Japan demand should continue to rise toward the end of the year, ahead of the expiration of the investment tax credit for solar cell power generators.

2) Europe: Largest solar power consumer Europe takes up 60% of Europe consumes over 60% of total solar power generated globally, driven by 1) high global solar cell demand interest in protecting the environment, 2) promotion of renewable energy as a means of job creation, 3) low energy self-sufficiency rates, and 4) expensive electricity.

Solar power generation Demand is forecast to rise in Europe and remain strong until 2015, spreading from Germany costs to equal electricity to Italy, Greece and France. Electricity is very expensive in European nations; in Italy, solar rates in 2013 power generation costs already equal general retail electricity rates. If solar power system installation costs fall to US$2.5/watt, the power generation costs should fall to a similar level in all European nations by 2013~2014 (estimates by Suntech).

Investments in new and Furthermore, investments in renewable energy will likely expand due to recent concerns renewable energy to over nuclear energy. As of 2007, nuclear power plants accounted for 16% (131GW) of total increase due to radiation electric power generation in Europe (OECD). If government budgets for nuclear power fears generation are diverted to renewable energy, the industry should grow much faster than expected. Indeed, many European nations have already started to reconsider their nuclear power plans, and are intending to expand their renewable energy budgets.

In 2011, we expect Germany to remain the largest solar cell market with a capacity of 7GW (flat YoY) and Italy to lead market growth with demand growing to 3.5GW.

Germany is anticipated to cut FiT by an additional 16% in 2H11, but profitability should remain intact thanks to a decline in solar cell module prices. Meanwhile, the installation of solar power generation facilities should increase ahead of a reduction to FiT in 2012.

Italian subsidy cuts In Italy, solar power generators should maintain high profitability despite a scheduled cut FiT probably smaller than in 2H. According to various media reports, the government may not cut FiT at the request of expected several local solar power generation companies.

There are some risks as well. European governments may reduce subsidies for solar power generation due to financial burdens (e.g., bigger-than-expected cuts to FiTs and installation caps). In 2008, Spain experienced a significant contraction in market size following the introduction of an installation cap.

Governments unlikely to At this point, we believe that the European nations will remain generous, as 1) public reduce financial support interest in renewable energy has increased in the wake of the nuclear crisis in Japan, 2) the job market needs to stabilize, and 3) financial support for solar power generation comes from electricity bills, not the government budget.

3) U.S.: Solar cell demand to grow to 2.3GW in 2011 and to 25GW by 2020

Demand is growing in The U.S. is the largest electricity consumer in the world with power capacity of 1,000GW as some states, namely of 2010. However, demand for new solar power facilities stagnated at 900MW. Although the California U.S. established mid- to long-term renewable energy targets, the government has only provided indirect support, such as tax benefits. Thus, the solar cell market has expanded at a slower pace than in Europe. However, demand is growing steadily driven by states with ample sunlight and a keen interest in the environment, namely California.

Demand is projected to In 2011, solar cell demand is projected to reach 2.3GW, exceeding 2GW for the first time in exceed 2GW in 2011 history. Solar cell companies are pushing ahead with large-scale solar power plant construction. In addition, demand for solar power facilities is expected to increase sharply before the Solar Investment Tax Credit (ITC) expires at end-2011.

Solar energy to account Solar cell demand growth is forecast to accelerate in line with the downtrend in power for 10% of all power generation costs. First Solar, a U.S.-based thin-film solar panel maker, plans to reduce power generation in 2020 generation unit costs to half of the 2009-level in 2014, which should help solar energy compete with fossil fuel energy and trigger full-scale growth of the solar cell industry. We expect growth in solar cell demand to take off after 2015, with newly installed capacity and accumulated capacity reaching 25GW and 100GW (10% of the entire power capacity), respectively, in 2020.

4) China/India: Require large-scale power generation capacities

Solar cell demand Solar cell demand in China and India is projected to expand from 674MW in 2010 to 1.7GW projected to expand in 2011. Solar power capacity accounts for just a small portion of the two nationsÊ power from 674MW in 2010 to production. They have been slow to adopt solar energy due to high generation costs. 1.7GW in 2011 However, solar cell demand in these countries should grow sharply in line with a decline in High growth potential generation costs. First, they are likely to use renewable energy to meet new electricity thanks to falling demand needed for economic growth. (In 2020, power capacity requirements are expected generation costs to exceed the 2010-level by W385GW.) Second, China and India are anticipated to expand support for solar cell manufacturers. China is the largest solar cell and module producer in the world.

If China and India both increase the percentage of solar power out of total electricity production to 4%, their newly installed solar power capacity is projected to grow to 43GW with an accumulated capacity reaching 134GW.

2. Polysilicon supply to remain tight until 2012

Polysilicon market is The global polysilicon market is increasingly polarizing despite its high growth potential and polarizing profitability. While leading companies are aggressively expanding capacities based on strong cost competitiveness, second-tier and below companies are finding it difficult to expand capacity due to weak competitiveness in terms of production costs and quality. In addition, the Chinese government began to control less competitive domestic companies. As a result, the polysilicon market is starting to be dominated by a handful of leaders.

From 4Q10 to 4Q11, We project polysilicon supply will remain tight until 2012. Production capacity at major ChinaÊs module capacity module manufacturers in China is expected to increase by 5GW YoY in 4Q11. However, the to increase by 5GW vs. combined production volume at six leading companies is forecast to only expand by 2GW. polysilicon capacity to Thus, the supply shortage is unlikely to ease for a considerable period of time. Although increase by 2GW major producers plan to ramp up production in 2012, the supply of high-purity silicon is expected to remain short.

Cost and quality Meanwhile, competition in the global polysilicon market will likely intensify after 2013 due to competition to intensify capacity expansion at existing players and the entry of new players. In the past, only a small after 2013 number of companies in advanced economies were capable of producing polysilicon due to high technology barriers. However, the barriers have lowered significantly thanks to the help of specialized equipment producers and production consultants. As a result, large companies (with sufficient capital) in search of next-generation growth engines are increasingly entering the market.

IV. Investment points

1. Polysilicon prices to stay robust on strong solar power demand

OCIÊs operating profit to In 2011, polysilicon prices are anticipated to stay high, driven by greater-than-expected solar show a CAGR of 53% power demand. Given that OCIÊs polysilicon production is forecast to expand 68% in 2011 during 2010~2012 following aggressive capacity expansion, we forecast its operating profit to surge 68% YoY this year. The companyÊs operating profit is expected to show a CAGR of 53% during 2010~2012, as: 1) high-purity polysilicon supply is forecast to remain tight until end-2012, and 2) OCIÊs production costs are projected to drop on the launch of a new factory.

Solar power demand to Solar power demand is likely to grow to 21GW this year, beating market expectations. rise in 2011 Concerned about the potential negative effects of nuclear power in the wake of the crisis in Japan, European governments are unlikely to reduce their budgets for solar power subsidy programs. The solar power markets in the U.S. and China are also expected to grow to 2GW and 1GW, respectively. Given that current solar module prices will keep the profitability of solar power plants high, demand should remain high until governmentsÊ subsidies shrink in 2012.

Polysilicon prices to stay Among supply chain materials for solar power generation, polysilicon is in the tightest supply. high in 2011 on supply Although a number of players have entered the market over the past several years, only a scarcity few top-tier firms (with cost and quality competitiveness) have pushed ahead with aggressive capacity expansion. Production at the six largest polysilicon producers is likely to increase by only 2GW YoY in 4Q11 (vs. a 5GW increase in module capacity in China).

2. Stiff competition after 2013 unlikely to hamper growth

Although competition in the polysilicon market is anticipated to stiffen after 2013, we believe that OCI will maintain its competitive position in light of its high quality products and strong cost competitiveness.

High-purity silicon OCI is producing polysilicon that displays purity comparable even to that of semiconductors. should enable cell OCI estimates that its high-purity polysilicon will enable cell makers to cut production costs makers to reduce costs by 43%. If the polysilicon market enters oversupply, high-purity polysilicon is likely to be by 43% priced at a premium relative to other types of silicon.

Close partnership with OCI also has strong cost competitiveness. Polysilicon production costs are mostly consist of core equipment depreciation expenses, raw material expenses, and energy expenses. As such, the efficient producer GT Solar operation of productive but low-priced equipment should be the key to the improvement of cost competitiveness.

Production expansion OCI has been a close business partner of GT Solar since they jointly developed core equipment through debottlenecking for polysilicon production in 2008. In addition, the company has proved its efficiency by technology expanding the capacity of its third factory·without additional investments·using its debottlenecking technology. If the third factory begins full operations in 2012, the companyÊs polysilicon production costs are projected to decline to US$25/kg·the worldÊs top-tier level.

V. Earnings forecasts

1. 1Q Earnings to beat market consensus thanks to robust polysilicon prices

2011 OP to soar by 68% We expect OCIÊs operating profit to increase at a CAGR of 53% to W1.7tr in 2012, backed YoY to W1.2tr by 1) solid polysilicon prices and 2) aggressive capacity expansion. We forecast 2011 sales and operating profit to rise by 29% and 68% YoY, respectively.

In 1Q11, operating profit is projected to exceed market consensus, reaching W290.5bn, aided by 1) higher-than-expected polysilicon prices and 2) the faster-than-anticipated operation of the third plant. Strong polysilicon prices will likely continue into 2Q11. Operating profit is forecast at W340.9bn during the quarter. Although polysilicon prices are expected to decline in 2H, production costs are likely to plunge from 4Q once the debottlenecking facility at the third factory begins full operations.

VI. Financial status and risks

1. Risks: Rights offering and contraction in solar cell demand

Risks facing OCIÊs share performance include: 1) the likelihood of a rights offering to fund additional investments and 2) a possible polysilicon supply glut due to contraction in solar cell demand.

Investment in plant #5 Currently, OCI is considering the expansion of plant #5. Capacity expansion by 20,000 might require rights tonnes/year would require the company to invest W1.5~2tr. If the company funds the offering; Mid- to long- investment through a rights offering, it might lead to overhang. However, the negative term impact to be impact should be limited considering that the new investment would boost the companyÊs limited mid- to long-term growth. In addition, OCI boasts strong competitiveness in the polysilicon market.

Solar cell demand As global solar cell demand is propped up by government support in Europe, demand could unlikely to decrease in shrink if support dwindles. Module prices would fall on the back of a solar cell supply glut 2011 from lower demand, adding to downward pressure on polysilicon prices. In our view, the risks are also limited, since we project solar cell demand will remain robust through 2011.
