OWENS CORNING (NYSE: OC)

Essentials Positioned for Growth Through a Strong Strategic Global Presence

Restructuring and Cost Cutting are major keys to future success.

OC went through an organizational restructuring in 2015, separating its Building Materials segment into Roofing and Insulation, resulting in a 1.35% decrease in COGS. These savings are expected to be maintained going forward. The firm has also shuttered inefficient composites plants in Japan and China, lowering operating leverage and boosting profitability. EBIT margins grew 1.57% (7.9% to 9.5%) in the last twelve months and we forecast a peak at 11.7% in 2017.

Initiate OC with a BUY Rating and a Target Price of $50.48. Our target price is based off a five-year Sum of Parts (SOP) DCF, Pro-forma Financial Statement DCF, and Relative Valuation; because of OC’s diverse segments and areas of operations. Given the spread of its products and operations, we see OC well positioned to capitalize on its economies of scale with industry demand, and is currently undervalued by 18.61%.

OC holds leadership positions in all three industries it competes within: Composites (35.2% of total revenue), Roofing (33.2%), and Insulation (31.6%). Within the Insulation industry, OC PINK® has a 70% brand recognition among consumers, allowing OC to charge a premium at the retail level. Brand recognition has spilled over into sales of OC’s other business lines. Discounts on roofing products have decreased, indicating a strong ability to dictate pricing in the roofing segment.

Owens Corning’s operations are highly sensitive to global economic cycles. It is especially sensitive to the US housing market as it derives 59.7% of its earnings from North American construction and remodeling activity.

BUSINESS SUMMARY

Since its inception in 1938, Owens Corning (NYSE: OC) has provided innovative glass fiber material solutions made in plants ranging from its world headquarters in Toledo, Ohio to its Thermal and Acoustical Insulation plant in Guangzhou, China. Today, OC enjoys leadership positions in all its industries, operates in 26 countries, and employs over 15,000 people. In the first three quarters of 2015, the firm generated net sales of $4.08 billion across three segments: Composites (35.2% of total revenue), Roofing (33.2%), and Insulation (31.6%). The Building Materials Group was eliminated and split into the Insulation and Roofing segments in 2014 to streamline management and cut company costs by $9 million. OC filed for bankruptcy in 2000 as a result of 243,000 asbestos-related claims against the company. The company emerged from bankruptcy in 2006 with an investment grade bond rating and has since maintained a strong balance sheet with ample liquidity ($1.8 billion in current assets as of 3Q15). OC currently has a net debt to total equity of 51.89%, which is in line with their five-year average of 51.17%. In addition to $600 million and $400 million in senior notes with 2022 and 2024 maturities, respectively, OC has access to $800 million in senior revolving credit. OC’s PINK® insulation products, with the Pink Panther™ as its mascot, achieve a brand recognition rate of 70% among consumers. This has created success in the retail home center channel, through distributors such as Home Depot and Lowe’s, causing a spillover in brand recognition across all three business segments. OC operates the broadest asphalt plant network in the industry, consisting of 14 roofing manufacturing sites and 16 shingle production lines. This, combined with OC’s vast distribution network and proprietary fiberglass composites knowledge, allows OC to serve regional markets across the nation cost effectively. The firm grew its quarterly dividend payout from $0.16 per common share in 2014 to $0.17 per share in 2015 and has reaffirmed its commitment to maintain dividends through the next business cycle. OC is expecting FYE 2015 EBIT to be between $460 to $500 million due to increases in volume and improvements in pricing as a result of estimated US housing starts of 1.1 million in 2015. Corporate and interest expenses for 2015 are estimated to be $110 million each while CAPEX are expected to be $380 million due to the construction of a non-woven composite plant in Gastonia, North Carolina.

MANAGEMENT AND GOVERNANCE OC’s management has been the backbone behind the company’s growth and increased profitability. Acting as CEO since 2007, Michael Thaman has extensive knowledge of OC and its operations. Thaman joined OC in 1992 and has since worked in a variety of positions ranging from President of the Engineered Pipe Systems Business in 1997 to CFO in 2000. Other key executives, such as Brian Chambers and Julian Francis, have helped spur growth and greatly increase efficiency. Additional details about these executives and other key management can be found in Appendices 1, 2a and 2b. In January 2016, OC has been recognized by Chief Executive, ranking 11th on their “2016 Best Companies for Leaders” for their extensive leadership development efforts. The magazine cited OC's efforts to make “a concerted effort to really invest more time, energy and dollars in [their] leadership program”. They were the only company in the building products sector to be honored. By growing organically, OC fills middle and senior management positions with tenured employees more likely to be positively motivated and retained. OC’s board operates across five committees: Audit, Compensation, Governance & Nomination, Executive, and Finance. Board members serve three-year terms and have elections staggered into three tiers of expiration, making any attempted hostile takeover unlikely. Some of OC key corporate governance strengths are:

Shareholder Rights - Focusing on shareholder’s opinion and value maximization, OC implemented a “say-on-pay vote” in 2014 that allows investors to veto excessive executive compensation.

Board Oversight – OC’s board oversight is led primarily by the Governance & Nomination Committee. This committee relies on board assessments that aim to evaluate each of the other committee’s performance as well as to identify potential issues the committees may face.

Board Composition - According to EY, the average level of independence among mid-cap boards was 80%. This means the OC board, at 92%, is more independent than the average mid-cap board.

Executive Compensation - OC utilizes Meyer & Partners compensation consultants to assist in setting executive compensation. As a result, 84% of CEO and 73% of NEO compensation is linked to a performance target.

BUSINESS SEGMENTS Composites  Segment The Composites segment produces glass fiber products used to reinforce and improve the strength and stiffness of other materials. Composites are stronger and/or lighter than traditional materials such as wood and steel. OC manufactures glass strands which are used in nearly 500 glass fiber products with over 40,000 end-use applications. These products serve seven primary markets: transportation, electronics, marine, infrastructure, wind-energy generation, insulation, and roofing (See Table 1 and Figure 4). OC plans to bring a new facility in Gastonia, NC online in 2016. According to Steven Vermeulen, Vice President and Managing Director of Engineered Solutions, “building a new site is a great opportunity for us to install the newest, most advanced manufacturing technology” and that “with our Gastonia plant, we’ll be able to meet the growing demand for Sustaina® non-woven products”. These bio-based products are used in building applications, such as vinyl flooring and ceiling backings, and represent a growing product segment. Table 1: Main Composites Solutions Primary End Markets Chopped Fibers Transportation, Automotive, Electronics, and Appliances Continuous Fibers Infrastructure (ex. Power & energy) Fabrics Wind energy, Defense, Aerospace, and Recreation Mats Roofing Shingles OC Composites currently ranks #1 in market share in the Americas and Europe with 46% and 30% of market revenues, respectively (See Figure 5). The composites industry is stable and growing. Glass fibers demand has grown at 1.6 times global industrial production growth. Within OC’s composites segment, 61% of revenues are international followed by 39% of revenues coming from the US and Canada. Compared to 3Q14, 3Q15 EBIT increased by $29m on strong volume, better pricing, and manufacturing performance, pushing FYE 2015 EBIT estimates to exceed FY2014 by $80m. OC’s composites business utilized a growth strategy consisting of: cost leadership, price realization, capital efficiency, and product leadership. As a result:

75% of manufacturing networks operates below average competitor delivery cost. OC introduced 50 new products in the past 36 months, which are expected to represent

20% of total composites revenue. Excess inventories were depleted, realizing $60m in accumulated price appreciation since

2013. OC entered a strategic alliance and long-term supply agreements, allowing for increased

supply availability in exchange for technology. A strong dollar lowered revenues for facilities in Russia, Europe, and Brazil. However, lower costs and price increases cancelled out the negative currency effect on EBIT margins. CAPEX are primarily driven by rebuilding the glass furnaces used in the production process every 10 to 12 years. However, the severity of the financial crisis disrupted the historical norm of rebuilding 30% of furnaces every four years, resulting in low CAPEX from 2009 to 2012 and unusually high CAPEX from 2013 to 2016. Management guidance estimates CAPEX will return to pre-crisis levels in 2016. Taking all of these factors into account, Composites is the most attractive and profitable segment of OC. Roofing/Asphalt  Segment OC offers roofing and asphalt solutions for residential, commercial, and industrial use, with residential repair/remodeling for the US and Canada (74%) representing the most revenue by end market followed by commercial & industrial use for the US and Canada (16%) and new residential construction for the US and Canada (10%). They offer three different shingle families: Traditional, Architectural, and Specialty. Each family has a number of different shingle offerings each with

differing wind resistances, algae resistances, warranties, colors, and advantages for different climates. Every shingle offering fits into the OC Total Protection Roofing System™, which includes Berkshire® Hip & Ridge Shingles, VentSure® Ventilation Products, Underlayment Products, Starter Shingle Products, and Self-Sealing Ice & Water Barrier Products (see Appendix 5). This Total Protection Roofing System™ has helped OC grow their Roofing Components sub-segment at an 11% CAGR. Roofing demand is primarily driven by the need to replace existing shingles due to age (60m ft2 in 2015), weather related events (28m ft2), and new construction (19m ft2). Historically, OC has averaged a 16% EBIT margin since 2012 within the Roofing segment, expects margins to remain in the mid-teens through 2019 and grew EBIT from $58m in the third quarter of 2014 (12% margin) to $103 million in the third quarter of 2015 (21%) while growing revenues from $200m (14%) to $213m (15%) from YTD 2014 to YTD 2015 (as of 3Q). These high EBIT margins are due, in part, to joint product innovation and cooperation with OC's composite segment resulting in low supply costs. This joint innovation has results in the chopped glass and mat fiber used in roofing shingles. OC is well positioned to service all channels in the roofing industry, including roofing distributors like Beacon Roofing Supply, building materials distributors like Prime Source Building Products, home centers like Lowe’s, and lumberyards like 84 Lumber. Traditionally, OC sees a third of their roofing volume occur in the first quarter which draws volume from the third and fourth quarters thanks to seasonal weather patterns. EBIT performance for 2015 is expected to be in line with 2014 ($392m). OC has not fully realized the effects of low oil prices due to asphalt price lag. However, with oil expected to remain low in the near term, we expect to see asphalt depreciation in 2016 and a lower profit. Roofing sales from new construction and re-roofing activities represent 20% and 80% of segment revenues, respectively. New construction sales performed in a predictable way during the economy recovery, while re-roofing activities underperformed. While economic conditions remain important, managements claim that weather represents 30% to 40% of re-roofing demand and future demand could greatly deviate from our expected sales growth rate 7% YoY through 2019. OC is also expanding into the $2bn roofing components market with its Synthetic Underlayment and Ice & Water Shield products. Management’s plan for future growth is to maintain a competitive advantage through a price and cost gap by focusing on the following:

Increasing/maintaining brand recognition R&D efforts expands across applications in all business segments Vertical integration Developing a flexible manufacturing network

Insulation  Segment OC is most notably known for their Pink Panther logo and PINK colored fiberglass-based insulation products. The PINK brand drives much of OC’s popularity and management believes it is crucial to maintaining customers. These products are used in commercial, residential, and industrial applications for acoustic and thermal purposes. OC FIBERGLAS™ 700 Series Insulation, for example, reduces heat and noise transfers while maintaining the best rating for flame spread. From 1985 to 2008, OC Insulation achieved an average EBIT margin of 15%. The US housing downturn caused that margin to drop to a trough of -8% in 2011. Since then, increasing housing starts has allowed OC to enjoy 17 straight quarters of margin improvement. EBIT margin stands at 12% of sales in the most recent quarter and OC believes it will remain in the double digits for the fourth quarter of 2015 and all of 2016. The Insulation segment has the majority of its operations in the US and Canada with residential new construction, commercial and industrial, and repair and remodel accounting for 40%, 24% and 20% of revenue, respectively (See Figure 9). Growth in these markets are driven primarily by increasing housing starts, adoption of greener building codes, aging house stock, and urbanization. In 2005, 2.1 million housing starts led to a 100% utilization of OC plant capacity. Responding to the drop in demand in the subsequent housing crisis, OC mothballed capacity to decrease fixed costs. This year, housing starts of 1.2 to 1.4 million have translated to a utilization of 73% of the current capacity which has required OC to restart the previously mothballed capacity. As the housing market continues to recover, price realization and increased operating leverage, estimated at 50%, are expected to increase revenue by 10% for the second half of 2015 relative to the same period in 2014.

INDUSTRY OVERVIEW & COMPETITIVE POSITIONING

Composites  Industry The global composites market is expected to grow at a 4.3% CAGR1 over the next five years. By 2020, Asia and North America are expected to capture 51% and 29% of market share respectively, versus 50% and 16% in 2015. Composite materials have diverse applications with aerospace, automotive, and construction registering the highest estimated CAGR of 10.2%, 8.3%, and 7.5% respectively through 2019. Their strength, light weight, and relatively low cost make composites promising alternative tool of steel and wood. Composites industry sales are expected to grow at 1.5x global GDP growth as composites are used to replace these traditional materials.

Fiberglass Fiberglass is a specific type of composite, comprising of plastic reinforced with glass fiber. The global market for fiberglass is a $7.5 billion industry that is expected to grow at a CAGR of 5 to 7% with global shipments growing at 1.6x industrial production growth. OC’s global competitors include PPG Industries, Johns Manville, Chongqing Polycom International Corp, and several China-based suppliers. Seeing that fiberglass products have become commoditized with little differentiation between manufacturers, we believe that pricing is primarily determined by global production capacity and idle capacity will increase price competition. However, as Chinese competitors begin to focus on boosting profitability, we have seen slowing capacity expansion contribute to increases in global utilization rates throughout the industry. From 2015 through 2018, global utilization rates are projected to rise above 90%. We anticipate this will increase manufacturers’ ability to fix selling prices and achieve higher operating margins. OC is the global leader in the glass composites industry with a market share above 30%. Its dominance in the Americas contributed to 46% of OC Composite revenue in 2014. With only five plants in Asia, however, OC derives just 10% of its composites revenues from China vs. its competitors’ average of 26% (Figure 5). The firm is at a disadvantage in this region given that price and quality are similar among industry players. It is worth noting that a strong dollar will dwindle revenues generated abroad (Appendix 6) Even so, we forecast the currency effect should not have material impact on share price given that the rising capacity utilization will enable producers to stabilize prices and charge a higher markup that compensates for the exchange loss.

Roofing  /  Asphalt  Industry Roofing was a $20 billion industry in 2015 with residential shingle accounting for 58% of market. The industry grew at a 4.7% CAGR from 2010 to 2015 due to a recovering housing market and is expected to grow at a 3.9%2 CAGR through 2017. Since roofing is a mature and saturated industry, we expect industry revenue will closely track US economic activity.

While sales growth will be constrained by the interest rate hike in the short run, we believe that roofing demand is delayed rather than cancelled since 83% of the demand is triggered by necessary repair/remodeling. As a result, we forecast the roofing industry revenue to grow at 3.9% in 2016 despite the recent rate hike by the Federal Reserve. We found that OC’s roofing sales have correlation coefficients of 0.014 and 0.18 with new housing starts and existing home sales, respectively, which are not reliable predictors of roofing sales (Appendix 7). Given that shingles are a durable good, we observe that the disposable personal income on prior half year serves as a better leading indicator with a correlation coefficient of 0.26 with OC's roofing sales (Appendix 8). We estimate that OC’s roofing sales will rise by $11m for every 1% increase in disposable personal income. However, improved design and materials have extended the useful life of newer shingles, which will affect producers in the long run as replacement cycles are extended.

Asphalt shingles command 55% and 91% share of residential and commercial roofing market which equates to a 69% overall market share (Figure 12). This leads to substantially lower installation costs. Shingles of other materials cost 1.7 to 3.2 times as much as their asphalt counterpart. Although other materials have gained popularity because of their aesthetic value, longer durability, and cooling effect, we believe that these benefits will not materially change the market share given their much higher installation cost. We forecast that shipments will rise to 112 million square-feet in 2016 with higher demand resulting from a 16% increase in new construction and a 10% increase in weather-related events caused by El Niño, increasing extreme rainfall and floods risk in the Southern US (Appendix 9)

The North American roofing industry is highly consolidated with four major players, in order of market share: GAF/ELK, Owens Corning, CertainTeed, and Tamko. These four firms represent more than 90% of the market. Industry operating margins declined in the first half of 2015 as a result of price competition. These margins are predicted to recover in the second half of 2015 now that overall production capacity is constrained, leading also to price stability. Buyers tend to take advantage of OC’s off-season discounts to boost their inventories, as OC shipped an average of 35% of annual sales during 1Q12 and 1Q14. Starting in 2015, OC has eliminated its winter discounts in order to maintain its gross margin and smoothen its delivery cycle. We believe the elimination of discounts signals that industry production is near full capacity and that demand is strong enough for the industry to more strongly enforce pricing.

OC is the second largest manufacturer of asphalt shingles in North America. It generates 73% of its roofing revenue from residential repair/remodeling. The segment is thus highly exposed to re-roofing demand. We believe that OC has not fully realized the effects of low oil prices seeing that asphalt costs have retained a premium above the historical average due do extended lag time. OC is currently expanding its product portfolio by marketing roofing components, which is an estimated $2 billion industry and grew at an 11% CAGR from 2009 to 2015 (Appendix 5). Though OC has increased the attachment rate in roofing applications from $0.20 to $0.25 for every dollar spent on asphalt shingles, we expect that component sales are hard to increase further since this niche is already occupied by other producers. These measures lead us to expect 14.3% EBIT margins in FYE 2015 and 15.4% in FYE 2016.

Insulation  Industry

The US insulation market is estimated to grow at a 7.0% CAGR3, reaching $10.4 billion by 2019. With 48% of the market share, fiberglass insulation will maintain its dominance given its low cost. Residential insulation accounts for 64% of industry demand with 40% of residential demand resulting from new construction. We attribute recent industry growth to the housing recovery, new environmental codes that require builders to increase insulation per structure, and greater consumer awareness of insulation’s role in boosting energy efficiency. The US insulation industry is highly consolidated with the top three manufacturers controlling 80% of the market share. OC is the largest player with a market share above 35%, followed by CertainTeed, Johns Manville, and Knauf. We find that OC can charge a premium in retail chain stores with its highly recognized PINK brand. (Appendix 10) But we infer that its brand premium is less valuable to contractors because glass fiber is a commodity and industry competitors are quick to adjust prices to match OC. New housing construction is a key driver of insulation demand. Insulation sales have correlations of 0.81 and 0.69 with new housing starts and existing home sales, respectively (Appendix 11). OC’s management estimates that demand will increase 200M pounds for every 100,000 housing starts. OC inferred that the industry will run at a 90% utilization rate on 1.1M US housing starts and will operate near full capacity on 1.4M to 1.5M housing starts. We project that insulation EBIT margin can reach 11% in 2016 as the housing starts are expected to grow 12% in next year.

INVESTMENT SUMMARY We issue a BUY recommendation on Owens Corning with a target price of $50.48 from an equally weighted average of a Sum of Parts DCF ($47.90), a Pro-Forma Financial Statement DCF ($45.88), and a Relative Multiples Valuation ($57.67) due to the firm’s diverse operations. Since OC competes against strong competition in broad industries driven by different factors, the use of three separate valuation methods more accurately reflects OC’s true intrinsic value from conservative assumptions in our DCF models weighed against industry competition. We believe OC possesses competitive advantages and faces risks that the market has not accounted for at the current stock price of $42.56. Owens Corning operates in three business segments: Composites, Insulation, and Roofing. Composites remain the broadest and most attractive segment with over 40,000 end-use applications including electronics and transportation. Insulation has made the OC brand popular with the introduction of the Pink Panther™ logo and PINK® colored glass fiber insulation seen in many residential and commercial units. OC Roofing is driven by demand for shingles in new construction projects but has enjoyed an expansion of the Roofing Component business due to the OC Total Protection Roofing System™.

A key driver of growth for OC going into the future is their restructuring and cost cutting activities which have already led EBIT margins to increase from 7.9% to 9.5% (1.57% growth) over the last twelve months. We forecast this EBIT margin to peak in 2017 at 11.7% and step down to 10.2% in 2019. Based on our valuation, from 2015 to 2019, we forecast revenues to grow from $5,541m to $6,757m (22% growth), EBITDA (adj.) to grow from $830m to $1,032m (24.28% growth) and EPS to grow from $2.40 to $3.81 (59% growth). OC has beaten EPS estimates in each of the past four quarters (37% average beat) and has returned 36% year-to-date. In 1Q14, OC announced a quarterly dividend of $0.16 per share which, as of 1Q15, has been increased to $0.17 per share. OC has fully integrated their acquisition of Thermafiber and has announced the construction of a new facility in Joplin, Missouri to support growth in the insulation market. Further, OC will be opening a new facility in Gastonia, North Carolina in 2016 which will help meet growing demand for Sustaina® non-woven products. OC was recently ranked 11th on the “2016 Best Companies for Leaders” list, according to Chief Executive magazine. The list consists of 40 public companies and recognizes global leaders in leadership development.

VALUATION  3Q15  Results OC reported 3Q EPS of $0.96, beating consensus estimates of $0.68 by 41%, as well as beating analyst expectations by 37.07% over the last four quarters. Firm-wide LTM EBIT reached $506m and management guidance suggests that FYE 2015 EBIT will be in the range of $460m to $500m. Relative  Valuation   Our relative valuation of $57.67 is derived from the comparable companies median LTM EV/EBITDA multiple of 9.37x.

Discounted  Cash  Flow  Assumption For the SOP we used the pure play approach to find each operating segment's respective beta shown in Figure 16. OC has a weighted average after tax cost of debt of 2.1%, which we held constant for each segment. As a result of recent market activity the separated segments yielded a higher WACC then the collective firm (figure 17). For each segment’s estimated enterprise value we used the exit multiple method (EMM); where each segments multiple was the median LTM EV/EBITDA multiple of their respective comparable companies. OC's large deferred tax assets balance will keep the effective tax rate at 6.6% through 2019. We held the NWC components at the historical median; as Owens Corning maintains relatively stable levels of NWC (figure 18).

Table 2: NWC ($ in millions) 2015E 2016E 2017E 2018E 2019E(Increase) / Decrease ($24.8) ($37.7) ($39.6) ($41.7) ($43.9)

Furthermore, we allocated firm wide NWC across each segment proportional to total revenue when forecasting each segments’ FCF. For the future CAPEX and D&A we used management guidance and historical trends; CAPEX as a percentage of sales, and D&A as a percentage of CAPEX are shown in Figure 19. Sum  of  Parts  DCF Appendix 12 fully displays our SOP DCF and the implied share price of $49.70. Revenue growth rate is tied to global industry growth expectations for composites and domestic industry growth expectations for roofing and insulation, growing at a CAGR of 4.3%, 3.9% and 7.0% respectively between 2015 and 2019. Helping drive OC's roofing revenue is the rapid growth of the component products, which has seen an 11% YoY growth in revenues. Component products have boosted the attachment rate from $0.20 to $0.25 for every dollar spent on asphalt shingles. These measures lead us to expect 14.3% EBIT margins in FYE 2015 and 16% in FYE 2017, in roofing. With insulation yielding 70% brand recognition among home owners, OC has been able to grow residential demand steadily since 2012, as well as increasing price by $125m. Moreover, energy efficiency efforts have driven residential insulation demand, with 30% more light density insulation used in construction than in 2006. Based on current economic expectations, we expect insulation revenues to grow at 7% through 2019.

We expect composites CAPEX to be 7.7% of sales from 2017-2019, based on pre-crisis averages. 3Q revenues were up 12% YTD, due to demand growth and price increases. As a result, we see FYE 2016 EBIT margins of 10.1%, peaking at 10.5% before stepping to 8.7% as D&A normalizes. We expect insulation CAPEX to remain constant at the historical median of 6.5% of sales, as no major projects have been announced. OC’s insulation business had a LTM EBIT margin of 6.2%, with the expectation of reaching 10% EBIT margins by 2016. Pro-forma  Financial  Statement  DCF To better estimate total firm performance, we did a pro-forma for the Income Statement, Balance Sheet and Cash Flows Statement (shown in appendix 13a,b,c,d), followed by a DCF from the forecasted values tables 3a and 3b show the implied share price sensitivity between the EMM and PGR. The assumptions used in the SOP where aggregated for the pro-forma. We estimated that as OC's cash grows, management would increase the dividend payout ratio from the LTM rate of 30.76% to 35% in 2019. Values that were not estimated above were held constant. When calculating the implied share price, we took the average enterprise value given between the EMM and the perpetuity growth method (PGM). For the EMM we used the median EV/EBITDA multiple of 7.22x and for the PGM we assumed a rate of 3.3%, the IMF estimated global growth for 2015. With a firm wide WACC of 7.4% (see figure 17) our implied share price was $45.88.

Overview The financial position table above highlights our expectations of OC's performance through 2019. Since emerging from bankruptcy in 2006, OC's profitability and operations have seen considerable volatility, with net income having a standard deviation of $2,691m between 2006 and 2014, and total assets falling 18% between 2005 and 2010. However, moving forward, we expect net income to regain stability and grow at 5.7% CAGR as demand and operations normalize. OC's share price saw a 14.51% return compared to the S&P500's -7.56%. Cost  Cutting  Activities  Will  Amplify  Profitability   Management has taken a number of steps to increase profitability since 2006 through eliminating less desirable assets including:

Organizational restructuring 9 divestures Optimizing high potential facilities Shut underperforming facilities

As a result, OC reported 3Q EPS of $0.96, beating consensus estimates of $0.68 by 41%, leading us to expect firm wide EBIT margins to reach 11.7% by 2017 shown in figure 16. Positioned  Well  for  Global  Growth OC has been expanding both its production and product lines strategically for future global growth, aimed at products and geographic locations that will provide the best return. Such products and facilities include:

A fourth Chinese FIBERGLAS™ facility, which is already posting profits after operating for two years.

The acquisition and expansion of Thermafiber Expansion of "Sustainability" products and promotions such as "EcoTouch®"

Further, coupled with OC's share repurchase program and the aforementioned cost cutting measures, we expect to see unlevered free cash flow per share to grow at a 7.45% CAGR between 2015 and 2019 (shown in figure 24) and EPS to reach $3.81 by 2019, with a CAGR of 9.7%. Du  Pont  Analysis:  Drivers  of  ROE Table 4 shows a breakdown of OC's ROE. OC's ROE growth is driven by the increase in net profit margin, with a 11.183% change YoY compared to asset turnover and financial leverage at 0.855% and 1.446% change YoY respectively; resulting in a 13.75% increase YoY in ROE, reaching 6.06%, shown in figure 26. Future we expected ROE to be driven by increasing net profit margins and asset turning over, with ROE peaking at 8.92% in 2016 before stepping down to 7.57% in 2019; the increase in net profit margin can largely be attributed to OC cost cutting efforts. Financial leverage is expected decreases by 37bps from 2014 to 2019, as total shareholder equity growth outpaces total assets, and debt (net debt/capital) decreases by 6.9%.

Table 4:

INVESTMENT RISKS ECONOMIC  RISK:  Macroeconomic  Weakness  (ER  1) The largest risk facing Owens Corning is a global slowdown. OC’s business segments are highly cyclical. We see significant macroeconomic risks in OC’s three major regions. (See Appendix 14) Economic activity within the Eurozone remains stagnant: World Bank estimates Eurozone GDP growth to be just 1.8% in 2016. China is in the midst of grappling with a sharp slowdown in economic expansion after enjoying decades of tremendous growth. The 18% drop in the Shanghai Composite Index since January 1 only adds to the uncertainty. With the latest U2 unemployment rate of 5.0% and a forecasted GDP growth of 2.8% in 2016 by the World Bank, the United States is one of very few bright spot in the global economy at the moment. However, weaknesses in its largest trading partners may dampen economic growth in the short to medium term. The S&P 500’s 8.0% year-to-date decline as of Jan 15th reflects the market’s concerns.

ECONOMIC  RISK  2:  N.  Am.  Housing  Market  /  Consumer  Confidence  (ER  2) OC derives 59.7% of all sales from North America, 77.9% of which is dependent upon residential construction and remodeling. A slowdown in the housing market or a deterioration in consumer confidence will have a material impact on the company’s revenue and valuation. OPERATIONAL  RISK:  High  Operating  Leverage/Continuous  Production  (HOL) The firm incurs high fixed costs and requires high levels of capital spending regardless of business activity. In addition, the production process for insulation and composites are continuous in nature while demand is cyclical. In a downturn, OC will not be able to adjust supply to demand in the short run. REGULATORY  RISK:  Environmental  Regulations/Potential  Fines  (ENVR) OC has been deemed a Potentially Responsible Party under the Comprehensive Environmental Response Compensation and Liability Act. In the past, OC was ordered to pay significant compensatory damages to victims of the company’s asbestos products, contributing to the company’s bankruptcy in 2000. It is possible for the company to face a similar situation in the future. LEGAL/OTHER  RISK:  OC  is  a  Holding  Company  (HCO) OC depends on its subsidiaries for cash to meet its obligations. The ability of OC’s subsidiaries to pay dividends and other distributions is dependent on their operating results and the laws and regulations the subsidiaries operate within. MARKET  RISK:  Impact  of  recent  oil  volatility  (MR) Given the current environment in the oil industry and OC's recent shingle price decreases, continued decreases in oil prices have translated to lower asphalt costs and maintained margins in the roofing segment. Historically, OC has seen a three month lag between material oil price changes and their effect on asphalt prices. Currently, due to asphalt supplier's reluctance to sell at lower prices, OC is seeing an increase in lag to six months.

Appendix 14: Growth  is  slowing  in  all  of  Owens  Corning’s  major  markets. All Sources from FactSet unless otherwise noted

Europe Growth in the Eurozone has been sluggish since the European Sovereign Debt Crisis began in 2009. As the region’s largest economy, Germany achieved GDP growth of 1.7% in 2015 and remains the Eurozone’s economic powerhouse. However, since 4Q of 2014, the five largest economies in the Eurozone have all shown signs of slowing. Industrial production has also been slowing in Germany, France, and the UK. In comparison, Italy and Spain are enjoying a resurgence in industrial production, albeit from a low base. Unemployment in both countries remains persistently high.

Migrant Crisis – the ongoing arrival of refugees on the EU’s borders are causing significant social and political disruptions. Although primarily a humanitarian issue, the crisis will have social significant social and economic effects. Border controls, for example, have been re-imposed in several countries within the Schengen Area. This has already had direct economic costs in the form of delays in the flow of goods.

China After years of double-digit, investment-led growth, the Chinese economy is experiencing a sharp slowdown as it rebalances to become a consumption-based economy. In 3Q of 2015, growth slowed to 6.9%, the slowest since the global financial crisis in 2009. In the aftermath of the crisis, the government encouraged imprudent projects to maintain growth, resulting from the overall debt-to-GDP to grow from 160% of GDP in 2007 to more than 240% in 3Q15, according to calculations by the Economist. It is also worth noting that the ratio soared by 50% in the last four years alone.

There are concerns regarding the reliability of official data. For example, according to China’s National Bureau of Statistics, while growth declined from 10.2% to 6.9% from 1Q2011 to 3Q2015, the unemployment rate fluctuated between 4.1% and 4.0%. As China becomes a more important market for OC, the reliability of official data will become an issue. Finally, the recent turmoil in the Chinese equity market is caused by an immature market combined with an incomplete understanding of markets by participants and government regulators. Ineffective measures such as the blanket ban on short sales and the introduction of circuit breakers contributed to increase the very volatility they were meant to tame.

US The US Federal Reserve responded to the 2008 financial crisis with an unprecedented injection of liquidity, which has inadvertently caused equity valuations to be inflated in the United States. Shiller’s Cyclically Adjusted PE Ratio currently stands at 23.82x, well above the mean and median values, which are 16.65x and 16.02x, respectively.

Despite a slowdown in industrial production, there are encouraging signs that the US economy will continue to expand. The strength of the job market is reassuring. The U3 and U6 unemployment rates have fallen to 5.0% and 9.9% as of December 2015, respectively. In fact, the most recent U6 figure of 9.9% is the lowest since June 2008.

Consumer sentiment has also improved substantially in the past year. University of Michigan’s Index of Consumer Sentiment stands at 92.4 as at January 1, 2016, compared to 79.6 and 76.5 in January 2014 and January 2013, respectively.
