7. What is a wafer? A thin slice of semiconductor material, such as silicon crystal, used in the fabrication of integrated circuits and other micro devices. A solar wafer is a circular solar cell made from the entire wafer. Wafers are formed of highly pure, nearly defect-free single crystalline material. Wafers are the foundations upon which semiconductor and solar cells are built. Image provided by www.memc.com as of October 10, 2010www.memc.com

9. Industry Outlook Recent growth in the industry is not sustainable and is attributed to a rebounding effect from the recent economic downturn. Growth for the remainder of 2010 is expected to continue diminishing from it’s present 27% to 6.3%, by 2011 and remain at 6.3% for the year. Growth is then expected to fall to the 4-5% range for the next several years. Core growth in this industry is expected to come from cell phone sales and non-retail avenues, primarily commercial solar development and military use. Consumer electronics outside of the cell phone industry is viewed as a mature sector with little growth. Thin film technology promises to displace wafer technology within the solar industry at increasing rates and is expected by many to render wafer technology obsolete in time.

15. Acquisition Activities November 23, 2009 MEMC completed acquisition of privately held Sun Edison, a developer of solar power projects and North America’s largest solar energy service provider. (Paid with $314 million, 70% cash, 30% MEMC stocks) July 2, 2010 MEMC completed acquisition of privately held Solaicx. (Paid with $66 million cash, and plus $10 cash equivalent of investment in Solaicx.) The acquisition expected to be accretive to earnings per share in 2011. Based on the MEMC’s recent frequent acquisition activities, we expect more acquisition activities will be initiated in the near future.

16. SWOT Analysis Strengths ◦ Large Cash Reserves ◦ Production of polysilicon ◦ Internal sales to SunEdison Weaknesses ◦ Overcapitalized (Too much Capacity) ◦ Recent investments in old technology ◦ Competitors located in Japan / China ◦ Several highly diversified competitors ◦ Very low pricing power

17. SWOT Analysis Opportunities ◦ Further diversification ◦ Reductions to COGS ◦ Acquisition into new technology ◦ Increased adoption of SunEdison Power Plants Threats ◦ Slow/no growth economy ◦ Fiscal Austerity ◦ Protectionism ◦ Wide adoption of different technology ◦ IRS audit / Lawsuits

18. Porter’s Five Forces Bargaining Power Suppliers – Low ◦ MEMC produces Polysilicon ◦ Polysilicon price is market driven Threat of New Entrants – High ◦ Increased demand for existing fuels ◦ Competitors patents / innovations ◦ Semi business is already commoditized Barriers to Entry – Medium High ◦ High fixed capital costs / burn rate to start ◦ Need for constant R&D and innovation ◦ Govt subsidies and investor funds are available

19. Porter’s Five Forces Bargaining Power of Buyers – Very High ◦ Short contracts for Semi-wafers (3-6 months) ◦ MEMC is largely a price taker in Semi-wafers ◦ Clean energy is a “like” not “need,” or “want” ◦ Long term supply contracts for Solar wafers  Three out of four have since been renegotiated Industry Rivalry – Very High ◦ Multiple wafer companies competing on price ◦ Semi-wafers are highly commoditized ◦ Competition for subsidized projects ◦ Competition for adoption by competing technologies Semi-Materials and Solar-Materials Industry seems unattractive

28. MEMC Cost Control MEMC is completing the closure of their two largest manufacturing facilities 33% 1 by square footage compared to the total company to Malaysia. We estimate it will be able to produce 50% of the company’s total output at a 20% cost reduction. This effect has been incorporated into our model at diminishing returns over the next 10 years. 1 MEMC 10-K (.pdf version) dated December 31, 2009: p21

29. DCF Analysis-Revenue Estimate Sales Estimate is based on industrial analysis and comparison analysis We separate SunEddison and MEMC’s traditional business-Wafer COGS is calculated as a function of MEMC’s cost and SunEdison’s cost. The COGS Margin is declining. Implying their restructuring effect

32. Recommendation The stock is currently trading at $13.09. Our intrinsic value for WFR is $14.14. We therefore recommend a modified holding strategy. Sell the original 200 shares at $13.09 and repurchase them after the waiting period to capture the unrealized loss. Estimated cash to fund would be approximately $3,900 while maintaining our position.
