~~1. GENERAL (continued)~~

During the first quarter of 2021, the Company entered into a lease for a warehouse located near our manufacturing facility in Fort Smith, Arkansas that is expected to commence in 2022. The lease is for a to-be-constructed warehouse where the Company will serve as the construction agent for the landlord. At no point during the construction period will the Company control the underlying asset as defined in ASC 842 (Leases). This lease will result in finance lease right-of-use assets and corresponding lease liabilities of approximately $35 million at the time of lease commencement.

5. DERIVATIVE FINANCIAL INSTRUMENTS

The Company is exposed to, among other risks, the impact of changes in commodity prices, foreign currency exchange rates, and interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks, and does not enter into such transactions for trading purposes.

The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. Contracts with counterparties generally contain right of offset provisions. These provisions effectively reduce the Company’s exposure to credit risk in situations where the Company has gain and loss positions outstanding with a single counterparty. It is the Company’s policy to offset on the Consolidated Balance Sheets the amounts recognized for derivative instruments with any cash collateral arising from derivative instruments executed with the same counterparty under a master netting agreement. As of March 31, ~~2020~~2021 and December 31, ~~2019,~~2020, the Company did not have any amounts on deposit with any of its counterparties, nor did any of its counterparties have any amounts on deposit with the Company.

Derivative Fair Values

Our derivatives consist of natural gas forward swaps, cross-currency swaps, foreign exchange forward contracts and U.S. treasury rate lock agreements, all of which are over-the-counter and not traded through an exchange. The Company uses widely accepted valuation tools to determine fair value, such as discounting cash flows to calculate a present value for the derivatives. The models use Level 2 inputs, such as forward curves and other commonly quoted observable transactions and prices. The fair value of our derivatives and hedging instruments are all classified as Level 2 investments within the three-tier hierarchy.

Cash Flow Hedges

The Company uses a combination of derivative financial instruments, which qualify as cash flow hedges, and physical contracts to manage forecasted exposure to electricity and natural gas prices. As of March 31, ~~2020,~~2021, the notional amounts of these natural gas forward swaps was 72 million MMBtu (or MMBtu equivalent) based on ~~U.S. and~~ European indices.

In March 2020, the Company entered into a $175 million forward U.S. Treasury rate lock agreement to manage the U.S. Treasury portion of its interest rate risk associated with the anticipated issuance of certain 10-year fixed rate senior notes before the end of 2022. The Company intends to cash settle ~~these agreements~~this agreement upon a future issuance of ~~the~~certain senior notes thereby effectively locking in the U.S. Treasury fixed interest rate in effect at the time the agreement was initiated. The locked fixed rate of this agreement is 0.994%. The Company has designated this outstanding forward U.S. Treasury rate lock agreement, which expires on December 15, 2022, as a cash flow hedge.

6.5. GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill

The Company tests goodwill and indefinite-lived intangible assets for impairment during the fourth quarter of each year, or more frequently should circumstances change or events occur that would more likely than not reduce the fair value of a reporting unit below its carrying value.

No testing was deemed necessary in the first three months of 2021. The changes in the net carrying value of goodwill by segment are as follows (in millions):


	Composites		Insulation		Roofing		Total
Balance at December 31, 2020	$	57	$	532	$	400	$	989


Additions	3		0		0		3
Foreign Currency Translation	(1)		(9)		(2)		(12)
Balance at March 31, 2021	$	59	$	523	$	398	$	980

During the first quarter of 2020, the Company’s significant share price reduction during the ~~ongoing~~ COVID-19 pandemic was determined to be an indicator of impairment under ASC 350. The COVID-19 pandemic ~~will likely~~was expected to have a negative impact on results for the remainder of 2020 and ~~creates near-term~~create uncertainty in our markets.

As of the most recent annual goodwill impairment testing date (October 1, 2019), testing indicated that the business enterprise value for the Insulation reporting unit exceeded its carrying value by approximately 10%. As described in our 2019 Form 10-K, there was uncertainty surrounding the macroeconomic factors impacting this reporting unit and a downturn in these factors or a change in the long-term revenue growth or profitability for this reporting unit could increase the likelihood of a future impairment.

In the first quarter of 2020, the Company performed its ongoing assessment to consider whether events or circumstances had occurred that could more likely than not reduce the fair value of a reporting unit below its carrying value. The ~~valuation limitation from the Company’s recent share price decline, the~~ narrow cushion on the Insulation reporting unit and the high level of ~~near-term~~ macroeconomic uncertainty caused the Company to perform an interim goodwill impairment test as of March 31, 2020 over the Insulation reporting unit. After evaluating and weighing all relevant events and circumstances, and considering the substantial excess fair values for the Roofing and Composites reporting units, we concluded that it iswas not more likely than not that the fair values of these reporting units were less than their carrying values. Consequently, we determined that it was not necessary to perform an interim impairment test for the Roofing and Composites reporting units.

Based on the results of this interim testing over the Insulation reporting unit, the Company recorded a $944 million pre-tax non-cash impairment charge ~~related to the Insulation reporting unit~~ in the first quarter of 2020. This charge was recorded in Goodwill impairment charge on the Consolidated Statements of Earnings (Loss), and was included in the Corporate, Other and Eliminations reporting category. Consistent with the Company’s adoption of ASU 2017-04 in the first quarter of 2020, the impairment charge was equal to the excess of the Insulation reporting unit’s carrying value over its fair value. The overall enterprise fair value of the Company was limited by the recent decline in our share price. The reduction in fair value for the Insulation reporting unit, and corresponding impairment charge, was primarily driven by an increase in the discount rate arising from higher equity risk premiums that reflect significant uncertainty surrounding the effect from the COVID-19 pandemic and a decrease in the reporting unit's forecasted near-term cash flows.

~~The changes in the net carrying value of goodwill by segment are as follows (in millions):~~

Composites Insulation Roofing Total
Balance at December 31, 2019 $ 57 $ 1,479 $ 396 $ 1,932

The remaining balance of goodwill for the Insulation reporting unit continues to be at risk for future impairment. There continues to be uncertainty surrounding the macroeconomic factors impacting this reporting unit, and a sustained downturn, significantly extended recovery, or a change in the long-term revenue growth or profitability for this reporting unit could increase the likelihood of an additional future impairment. Additionally, changes in market participant assumptions such as an increased discount rate or further share price reductions could increase the likelihood of an additional future impairment.

Other Intangible Assets

The Company amortizes the cost of other intangible assets over their estimated useful lives which, individually, range up to 45 years. The Company's future cash flows are not materially impacted by its ability to extend or renew agreements related to its amortizable intangible assets.

5. GOODWILL AND OTHER INTANGIBLE ASSETS (continued)

In the first quarter of 2020, we performed an interim impairment test of certain indefinite-lived trademarks and trade names used by our Insulation segment, based on the macroeconomic conditions that precipitated the interim goodwill impairment test described above.

Based on the results of this testing, the Company recorded pre-tax non-cash impairment charges totaling $43 million in the first quarter of 2020 related to 2 of the Insulation trademarks and trade names. These charges were recorded in Other (income) expenses, net on the Consolidated Statements of Earnings (Loss), and were included in the Corporate, Other and Eliminations reporting category.

~~Fair values used in testing for potential~~Non-cash impairment of our trademarks are calculated using the relief-from-royalty method by applying an estimated market value royalty rate to the forecasted revenues of the businesses that utilize those assets. The assumed cash flows from this calculation are discounted atcharges included a ~~rate based on a market participant discount rate.~~

A pre-tax impairment charge of $34 million for a trade name used by our European building and technical insulation business, ~~was recognized due to the combined effect of lower expected sales following an immaterial divestiture in the first quarter of 2020, a decrease in the forecasted near-term cash flows,~~ and a ~~higher discount rate associated with the economic impact and uncertainty from the COVID-19 pandemic. A~~ pre-tax impairment charge of $9 million related to a trademark used on global cellular glass insulation ~~products was recorded due to a slightly lower sales outlook and a similarly higher discount rate associated with the economic impact and uncertainty from the COVID-19 pandemic.~~products.

Pension Plans

The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employee’s years of service and, for certain categories of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum funding requirements. In our non-U.S. plans, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average future service period of plan participants expected to receive benefits. In our U.S. plans, the unrecognized cost of any retroactive amendments and actuarial gains and losses are amortized over the average remaining life expectancy of the inactive participants as substantially all of the plan participants are inactive.

~~12.~~11. CONTINGENT LIABILITIES AND OTHER MATTERS

The Company may be involved in various legal and regulatory proceedings relating to employment, antitrust, tax, product liability, environmental, contracts, intellectual property and other matters (collectively, “Proceedings”). The Company regularly reviews the status of such Proceedings along with legal counsel. Liabilities for such Proceedings are recorded when it is probable that the liability has been incurred and when the amount of the liability can be reasonably estimated. Liabilities are adjusted when additional information becomes available. Management believes that the amount of any reasonably possible losses in excess of any amounts accrued, if any, with respect to such Proceedings or any other known claim, including the matters described below under the caption Environmental Matters (the “Environmental Matters”), are not material to the Company’s financial statements. Management believes that the ultimate disposition of the Proceedings and the Environmental Matters will not have a material adverse effect on the Company’s financial condition. While the likelihood is remote, the disposition of the Proceedings and Environmental Matters could have a material impact on the results of operations, cash flows or liquidity in any given reporting period.

Litigation and Regulatory Proceedings

The Company is involved in litigation and regulatory proceedings from time to time in the regular course of its business. The Company believes that adequate provisions for resolution of all contingencies, claims and pending matters have been made for probable losses that are reasonably estimable.

Environmental Matters

The Company has established policies and procedures designed to ensure that its operations are conducted in compliance with all relevant laws and regulations and that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment, including emissions to air, reductions of greenhouse gases, discharges to water, management of hazardous materials, handling and disposal of solid wastes, use of chemicals in our manufacturing processes, and remediation of contaminated sites. All Company manufacturing facilities operate using an ISO 14001 or equivalent environmental management system. The Company’s 2030 Sustainability Goals include significant global reductions in energy use, water consumption, waste to landfill, and emissions of greenhouse gases, fine particulate matter, and volatile organic air emissions, and protection of biodiversity.

Owens Corning is involved in remedial response activities and is responsible for environmental remediation at a number of sites, including certain of its currently owned or formerly owned plants. These responsibilities arise under a number of laws, including, but not limited to, the Federal Resource Conservation and Recovery Act, and similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company has also been named a potentially responsible party under the U.S. Federal Superfund law, or state equivalents, at a number of disposal sites. The Company became involved in these sites as a result of government action or in connection with business acquisitions. As of March 31, ~~2020,~~2021, the Company was involved with a total of 2021 sites worldwide, including 78 Superfund and state equivalent sites and 13 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company.

Remediation activities generally involve a potential range of activities and costs related to soil, groundwater, and sediment contamination. This can include pre-cleanup activities such as fact-finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology. Taking these factors into account, Owens Corning has predicted the costs of remediation reasonably estimated to be paid over a period of years. The Company accrues an amount on an undiscounted basis, consistent with the reasonable estimates of these costs when it is probable that a liability has been incurred. Actual cost may differ from these estimates for the reasons mentioned above. At March 31, ~~2020,~~2021, the Company had an accrual totaling $9$5 million for these costs, of which the current portion is $5$1 million. Changes in required remediation procedures or timing of

those procedures, or discovery of contamination at additional sites, could result in material increases to the Company’s environmental obligations.

~~13.~~12. STOCK COMPENSATION

Description of the Plan

On April 18, 2019, the Company’s stockholders approved the Owens Corning 2019 Stock Plan (the “2019 Stock Plan”) which authorizes grants of stock options, stock appreciation rights, restricted stock awards, restricted stock units, bonus stock awards and performance ~~stock~~share awards. At March 31, ~~2020,~~2021, the number of shares remaining available under the 2019 Stock Plan for all stock awards was approximately ~~3.5~~3.1 million.

Prior to 2019, employees were eligible to receive stock awards under the Owens Corning 2016 Stock Plan and the Owens Corning 2013 Stock Plan.

Total Stock-Based Compensation Expense

Stock-based compensation expense included in Marketing and administrative expenses in the accompanying Consolidated Statements of Earnings (Loss) is as follows (in millions):

Three Months Ended March 31,
2020 2019
Total stock-based compensation expense $ 11 $ 11


	Three Months Ended March 31,
	2021		2020
Total stock-based compensation expense	$	12	$	11

Stock Options

The Company has granted stock options under its stockholder approved stock plans. The Company calculates a weighted-average grant-date fair value using a Black-Scholes valuation model for options granted. Compensation expense for options is measured based on the fair market value of the option on the date of grant, and is recognized on a straight-line basis over a four year vesting period. In general, the exercise price of each option awarded was equal to the closing market price of the Company’s common stock on the date of grant and an option’s maximum term is 10 years. The volatility assumption was based on a benchmark study of our peers prior to 2014. Starting with the options granted in 2014, the volatility was based on the Company’s historic volatility.

The Company has not granted stock options since the year ended December 31, 2014. As of March 31, ~~2020,~~2021, there was no unrecognized compensation cost related to stock options and the range of exercise prices on outstanding stock options was $33.73 - $42.16.

The following table summarizes the Company’s stock option activity:

Restricted Stock Awards and Restricted Stock Units

The Company has granted restricted stock awards and restricted stock units (collectively referred to as “RSUs”) under its stockholder approved stock plans. Compensation expense for RSUs is measured based on the closing market price of the stock at date of grant and is recognized on a straight-line basis over the vesting period, which is typically three or four years. The Stock Plan allows alternate vesting schedules for death, disability, and retirement. The weighted average grant date fair value of RSUs granted in ~~2020~~2021 was ~~$63.65.~~$81.35.

The following table summarizes the Company’s RSU plans:


		Number of RSUs	Weighted-Average Fair Value			Number of RSUs	Weighted-Average Fair Value
Balance at December 31, 2019		1,515,706	$	51.70
Balance at December 31, 2020					Balance at December 31, 2020	1,419,454	$	54.99

Balance at March 31, 2021					Balance at March 31, 2021	1,407,500	$	59.08

As of March 31, ~~2020,~~2021, there was ~~$44~~$49 million of total unrecognized compensation cost related to ~~restricted stock.~~RSUs. That cost is expected to be recognized over a weighted-average period of ~~2.42~~2.54 years. The total grant date fair value of shares vested during the three months ended March 31, ~~2020~~2021 and ~~2019~~2020 was $19 million and ~~$18~~$19 million, respectively.

Performance ~~Stock~~Share Awards and Performance ~~Stock~~Share Units

The Company has granted performance ~~stock~~share awards and performance ~~stock~~share units (collectively referred to as “PSUs”) as a part of its long-term incentive plan. All outstanding performance grants will fully settle in stock. The amount of stock ultimately distributed from all performance shares is contingent on meeting internal company-based metrics or an external-based stock performance metric.

In the three months ended March 31, ~~2020,~~2021, the Company granted both internal company-based and external-based metric PSUs.

Internal Company-based metrics

The internal company-based metrics are based on various Company metrics and typically vest over a three-year period. The amount of stock distributed will vary from 0% to 300% of PSUs awarded depending on each award's design and performance versus the internal Company-based metrics.

The initial fair value for all internal Company-based metric PSUs assumes that the performance goals will be achieved and is based on the grant date stock price. This assumption is monitored quarterly and if it becomes probable that such goals will not be achieved or will be exceeded, compensation expense recognized will be adjusted and previous surplus compensation expense recognized will be reversed or additional expense will be recognized. The expected term represents the period from the grant date to the end of the vesting period. Pro-rata vesting may be utilized in the case of death, disability or approved retirement and awards, if earned, will be paid at the end of the vesting period.

External-based metrics

The external-based metrics vest after a three-year period. Outstanding grants ~~issued in or after 2018~~ are based on the Company's total stockholder return relative to the performance of the Dow Jones U.S. Construction & Materials Index. The amount of stock distributed will vary from 0% to 200% of PSUs awarded depending on the relative stockholder return performance. The fair value of external-based metric PSUs has been estimated at the grant date using a Monte Carlo simulation that uses various assumptions.

Employee Stock Purchase Plan

The Owens Corning Employee Stock Purchase Plan (ESPP) is a tax-qualified plan under Section 423 of the Internal Revenue Code. The purchase price of shares purchased under the ESPP is equal to 85% of the lower of the fair market value of shares of Owens Corning common stock at the beginning or ending of the offering period, which is a six-month period ending on May 31 and November 30 of each year. ~~At the approval date, 2.0 million shares were available for purchase under the ESPP. As of March 31, 2020, 0.3 million shares remain available for purchase.~~ On April 16, 2020, the Company's stockholders approved the Amended and Restated Owens Corning Employee Stock Purchase Plan which increased the number of shares available for issuance under the plan by 4.2 million shares. As of March 31, 2021, 4.1 million shares remain available for purchase.

Included in total stock-based compensation expense is $1 million of expense related to the Company's ESPP recognized during the three months ended March 31, 2021.

For the three months ended March 31, 2021, there were no non-vested restricted or performance shares that had an anti-dilutive effect on earnings per share. For the three months ended March 31, 2020, diluted earnings per share was equal to basic earnings per share due to the net loss attributable to Owens Corning. For the three months ended March 31, 2019, the number of shares used in the calculation of diluted earnings per share did not include 0.7 million non-vested restricted shares and 0.1 million non-vested performance shares, due to their anti-dilutive effect.

On ~~October 24, 2016,~~December 3, 2020, the Board of Directors approved a share buy-back program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (the “Repurchase Authorization”). The Repurchase Authorization enables the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and is at the Company’s discretion. The Company repurchased ~~1.3~~1.6 million shares of its common stock for ~~$81~~$131 million during the three months ended March 31, ~~2020,~~2021, under the Repurchase Authorization. As of March 31, ~~2020, 2.3~~2021, 7.9 million shares remain available for repurchase under the Repurchase Authorization.

~~15.~~14. INCOME TAXES

The following table provides the Income tax expense (in millions) and effective tax rate for the periods indicated:


		Three Months Ended March 31,										Three Months Ended March 31,

Income tax expense	Income tax expense	$	24		$	39		Income tax expense	$	59		$	24
Effective tax rate	Effective tax rate	-3		%	48		%	Effective tax rate	22		%	-3		%

The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended March 31, 2021 is primarily due to U.S. state and local income tax expense, U.S. federal taxes on foreign earnings, adjustments to valuation allowances against certain deferred tax assets, excess tax benefits related to stock compensation, and other discrete adjustments.

The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended March 31, 2020 is primarily a result of charges related to the impairment of goodwill and certain other indefinite-lived intangible assets recorded in the three months ended March 31, 2020, which were mostly non-deductible. Non-cash charges of $18 million were recorded in the three months ended March 31, 2020 related to adjustments to valuation allowances against certain deferred tax assets. Additional items which account for the difference between the statutory rate of 21% and the effective rate are the impact of recording U.S. state and local income tax expense, the impact of U.S. federal taxes on foreign earnings, and other discrete adjustments.

The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended March 31, 2019 is primarily due to U.S. state and local income tax expense, the impact of higher foreign tax rates, legislative changes as described in the following paragraph and other discrete adjustments.

On March 6, 2019, the U.S. Treasury and the IRS proposed regulations that provide guidance on determining the amount of a domestic corporation’s deduction for the global intangible low-taxed income (GILTI) and foreign-derived intangible income (FDII) recently added by the U.S. Tax Cuts and Jobs Act of 2017 (the "Tax Act"). The proposed regulations provide special rules in determining the deduction amount which adjusted the Company’s 2018 tax estimate resulting in an increase to tax expense of $12 million for the three months ended March 31, 2019.

~~The~~ Company continues to assert indefinite reinvestment in accordance with ASC 740 based on the laws as of enactment of the Tax Act.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

This Management’s Discussion and Analysis (MD&A) is intended to help investors understand Owens Corning, our operations and our present business environment. MD&A is provided as a supplement to, and should be read in conjunction with, our Consolidated Financial Statements and the accompanying Notes thereto contained in this report. Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in this report refer to Owens Corning and its subsidiaries.

GENERAL

Owens Corning is a leading global producer of residential and commercial building materials and of glass fiber reinforcements and other materials for composites. The Company has three reportable segments: Composites, Insulation and Roofing. Through these lines of business, we manufacture and sell products worldwide. We maintain leading market positions in many of our major product categories.

EXECUTIVE OVERVIEW

Throughout the first quarter of 2021, the COVID-19 pandemic continued to impact much of the globe and create uncertainty in the markets we serve. Despite this ongoing impact, we are continuing to focus on serving our customers, while taking significant precautions to provide a safe environment for our employees and customers. We remain hopeful that the impact of the pandemic will continue to lessen through effective distribution of vaccines and the continued resumption of widespread economic activity.

Net ~~loss~~earnings attributable to Owens Corning were ~~$917~~$210 million in the first quarter of ~~2020,~~2021, compared to ~~Net earnings~~net loss attributable to Owens Corning of ~~$44~~$917 million in the same period of ~~2019.~~2020. The Company reported ~~a loss of $866~~$301 million in earnings before interest and taxes (EBIT) for the first quarter of ~~2020~~2021 compared to ~~earnings~~a loss of ~~$118~~$866 million in the same period of ~~2019.~~2020. The Company’s first-quarter 2020 results included non-cash pre-tax impairment charges of $987 million driven by the economic uncertainties associated with the COVID-19 pandemic. The Company generated ~~$116~~$282 million in adjusted earnings before interest and taxes (“Adjusted EBIT”) for the first quarter of ~~2020~~2021 compared to $116 million in the same period of ~~2019.~~2020. See the Adjusted Earnings Before Interest and Taxes paragraph of the MD&A for further information regarding EBIT and Adjusted EBIT, including the reconciliation to net earnings (loss) attributable to Owens Corning. First quarter of ~~2020~~2021 EBIT performance compared to the same period of ~~2019~~2020 increased ~~$24~~$92 million, $43 million and $35 million in our Roofing, Insulation ~~segment,~~ and ~~decreased $13 million and $10 million in our~~ Composites ~~and Roofing~~ segments, respectively. Within our Corporate, Other and Eliminations category, General corporate expense and other increased by $4 million.

~~In our Insulation segment, EBIT in the first quarter~~Cash and cash equivalents were $605 million as of ~~2020 was $39 million~~March 31, 2021, compared to ~~$15~~$234 million inas of March 31, 2020, as a result of strong cash flow provided by operating activities, and lower cash paid for property, plant and equipment.

The spread of the COVID-19 virus in 2020 has caused an economic downturn on a global scale, as well as significant volatility in the financial markets. In March 2020, the World Health Organization declared the spread of the COVID-19 virus a pandemic.previously announced repurchase authorization (the "Share Repurchase Authorization"). As of ~~April 29, 2020,~~March 31, 2021, 7.9 million shares remained available for repurchase under the Company’s operations have been impacted due to the extent described in the paragraphs below and as discussed in our Results of Operations. The Company cannot at this time predict the impact that the COVID-19 pandemic will have on its financial condition and operations, although we are continuing to monitor our supply chain and orders from customers for COVID-19 pandemic-related changes.

In this time of uncertainty as a result of the COVID-19 pandemic, we are continuing to serve our customers while taking every precaution to provide a safe work environment for our employees and customers. We have enacted enhanced operating protocols to assure the safety and well-being of our employees, placed restrictions on non-essential travel, and otherwise adjusted work schedules to maximize our capacity while adhering to recommended precautions such as social distancing and complying with stay-at-home orders. We may have to take further actions that we determine are in the best interests of our employees or as required by federal, state, or local authorities.

As a result of the government-mandated shutdown in India, two of our principal manufacturing sites (Taloja, India and Silvassa, India) were temporarily idled. As of April 29, 2020, these sites are now in the process of resuming operations. We will continue to adhere to restrictions imposed by local governments in the jurisdictions in which we operate.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)

The impact of the COVID-19 pandemic continues to unfold. The extent of the pandemic’s effect on our operational and financial performance will depend in large part on future developments, which cannot be predicted with confidence at this time. Future developments include the duration, scope and severity of the pandemic, the actions taken to contain or mitigate its impact, the impact on governmental programs and budgets, the development of treatments or vaccines, and the resumption of

widespread economic activity. Due to the inherent uncertainty of the unprecedented and rapidly evolving situation, we are unable to predict with any confidence the likely impact of the COVID-19 pandemic on our future operations.

In the three months ended March 31, 2020, the Company's operating activities used $52 million of cash flow, compared to $151 million in the same period in 2019. The change was primarily driven by a smaller increase in operating assets and liabilities compared to the same period in the prior year.

The Company repurchased 1.3 million shares of its common stock for $81 million during the first quarter of 2020 under a previously announced repurchase authorization (the "Share Repurchase Authorization"). As of March 31, 2020, 2.3 million shares remained available for repurchase under the Share Repurchase Authorization.

INCOME TAX EXPENSE

Income tax expense for the three months ended March 31, 2021 was $59 million. For the first quarter 2021, the Company's effective tax rate was 22%. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended March 31, 2021 is primarily due to U.S. state and local income tax expense, U.S. federal taxes on foreign earnings, adjustments to valuation allowances against certain deferred tax assets, excess tax benefits related to stock compensation, and other discrete adjustments.

The realization of deferred tax assets depends on achieving a certain minimum level of future taxable income. Management currently believes that it is at least reasonably possible that the minimum level of taxable income will be met within the next 12 months to reduce the valuation allowances of certain foreign jurisdictions by a range of zero to $7 million.

Income tax expense for the three months ended March 31, 2020 was $24 million. For the first quarter 2020, the Company's effective tax rate was (3)%. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended March 31, 2020 is primarily a result of charges related to the impairment of goodwill and certain other indefinite-lived intangible assets recorded in the three months ended March 31, 2020, which were mostly non-deductible. Non-cash charges of $18 million were recorded in the three months ended March 31, 2020 related to adjustments to valuation allowances against certain deferred tax assets. Additional items which account for the difference between the statutory rate of 21% and the effective rate are the impact of recording U.S. state and local income tax expense, the impact of U.S. federal taxes on foreign earnings, and other discrete adjustments.

The realization of deferred tax assets depends on achieving a certain minimum level of future taxable income. Management currently believes that an immaterial amount of valuation allowances of certain foreign jurisdictions could be reduced within the next 12 months.

Income tax expense for the three months ended March 31, 2019 was $39 million. For the first quarter 2019, the Company's effective tax rate was 48%. The difference between the effective tax rate and the U.S. federal statutory tax rate

Table of 21% for the three months ended March 31, 2019, was primarily due to U.S. state and local income tax expense, the impact of higher foreign tax rates, legislative changes as described in the following paragraph and other discrete adjustments.Contents

On March 6, 2019, the U.S. Treasury and the IRS proposed regulations that provide guidance on determining the amount of a domestic corporation’s deduction for the global intangible low-taxed income (GILTI) and foreign-derived intangible income (FDII) recently added by the U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Act”). The proposed regulations provide special rules in determining the deduction amount which adjusted the Company’s 2018 tax estimate resulting in an increase to tax expense of $12 million for the three months ended March 31, 2019.ITEM 2.

Adjusted Earnings Before Interest and Taxes

Adjusted EBIT is a non-GAAP measure that excludes certain items that management does not allocate to our segment results because it believes they are not representative of the Company's ongoing operations. Adjusted EBIT is used internally by the Company for various purposes, including reporting results of operations to the Board of Directors of the Company, analysis of performance and related employee compensation measures. Although management believes that these adjustments result in a measure that provides a useful representation of our operational performance, the adjusted measure should not be considered in isolation or as a substitute for Net earnings (loss) attributable to Owens Corning as prepared in accordance with accounting principles generally accepted in the United States.

Segment Results

EBIT by segment consists of net sales less related costs and expenses and is presented on a basis that is used internally for evaluating segment performance. Certain items, such as general corporate expenses or income and certain other expense or income items, are excluded from the internal evaluation of segment performance. Accordingly, these items are not reflected in EBIT for our reportable segments and are included in the Corporate, Other and Eliminations category, which is presented following the discussion of our reportable segments.

NET SALES

In our Composites segment, net sales in the first quarter 2021 increased $65 million compared to the same period in 2020. The increase was primarily driven by higher sales volumes of approximately 8%. The remaining difference was driven by higher selling prices of $9 million, the favorable impact of translating sales denominated in foreign currencies into United States dollars and favorable product mix.

~~NET SALES~~

In our Composites segment, net sales in the first quarter 2020 decreased $19 million compared to the same period in 2019. The decrease was primarily driven by lower selling prices of $11 million and unfavorable product mix.

fixed cost absorption on higher production volumes of $15 million and favorable manufacturing performance of $5 million, excluding the impact of the winter storm event in Texas in February 2021, more than offset $7 million of input cost inflation and $6 million in higher transportation costs. Gains on settlements from contracts to purchase and sell wind-generated electricity of $14 million largely offset the $12 million unfavorable operational impact from the winter storm event.

OUTLOOK

The outlook for Insulation demand is driven by North American new residential construction, remodeling and repair ~~activity; and~~activity, as well as commercial and industrial construction activity in the United States, Canada, Europe and Asia-Pacific. Demand in commercial and industrial insulation markets is most closely correlated to industrial production growth and overall economic activity in the global markets we serve.

The following table shows how the Company utilized its primary sources of liquidity (in millions):

The Company issued $300 million of 2030 senior notes on May 12, 2020 subject to $3 million of discounts and issuance costs. Interest on the notes is payable semiannually in arrears on June 1 and December 1 each year, beginning on December 1, 2020. The proceeds from these notes were used for general corporate purposes.

The Receivables Securitization Facility and Senior Revolving Credit Facility both mature in ~~2022 and 2024, respectively.~~2024. The Company also has a term loan (the "Term Loan"), which requires minimum quarterly principal repayments, all of which have been paid as of March 31, 2020, and full repayment by February 2021. As of March 31, 2020, the Term Loan had $150 million outstanding. The company has no significant debt maturities of senior notes before the fourth quarter of 2022. As of March 31, ~~2020,~~2021, the Company had ~~$3.4~~$3.2 billion of total debt and cash and cash equivalents of ~~$234~~$605 million.

Cash and cash equivalents held by foreign subsidiaries may be subject to foreign withholding taxes upon repatriation to the U.S. As of March 31, ~~2020,~~2021, and December 31, ~~2019,~~2020, the Company had ~~$50~~$91 million and ~~$30~~$71 million, respectively, in cash and cash equivalents in certain of our foreign subsidiaries. The Company continues to assert indefinite reinvestment in accordance with ASC 740 based on the laws as of enactment of the tax legislation commonly known as the U.S. Tax Cuts and Jobs Act of 2017.

As a holding company, we have no operations of our own and most of our assets are held by our direct and indirect subsidiaries. Dividends and other payments or distributions from our subsidiaries will be used to meet our debt service and other obligations and to enable us to pay dividends to our stockholders. Please refer to page 1315 of the Risk Factors disclosed in Item 1A of the Company's Form 10-K for the year ended December 31, ~~2019~~2020 (the ~~"2019~~"2020 Form 10-K") for details on the factors that could inhibit our subsidiaries' ability to pay dividends or make other distributions to the parent company.

Our anticipated uses of cash include capital expenditures, working capital needs, pension contributions, share repurchases, meeting financial obligations, payments of quarterly dividends as authorized by our Board of Directors, ~~acquisitions~~ and reducing outstanding amounts under the Senior Revolving Credit Facility, Receivables Securitization Facility and Term Loan. A sustained significant decrease in revenue in the U.S. or excessive aging of the underlying receivables as a result of the impact of the COVID-19 pandemic could materially affect the collateral capacity limitation on the availability under the Receivables Securitization Facility.acquisitions. We expect that our cash on hand, coupled with future cash flows from operations and other available sources of liquidity, including our Senior Revolving Credit Facility and, to the extent available, our Receivables Securitization Facility, will provide ample liquidity to enable us to meet our cash requirements.

The agreements governing our Senior Revolving Credit Facility and Receivables Securitization Facility ~~and Term Loan~~ contain various covenants that we believe are usual and customary. These covenants include a maximum allowed leverage ratio and a minimum required interest expense coverage ratio. We were in compliance with these covenants as of March 31, ~~2020.~~2021.

Supplier Finance Programs

We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to reduce working capital and improve cash flow.Separate from those terms extension actions, certain of our subsidiaries have entered into paying agency agreements with third-party administrators.These voluntary supply chain finance programs (collectively, the “Programs”) generally give participating suppliers the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both the suppliers and financial institutions.The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers’ decisions to sell, or otherwise pledge as collateral, amounts under these arrangements.One of our programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary that, at the time of the respective program’s inception in 2015, was a guarantor subsidiary of the Company’s Senior Revolving Credit Facility.

The payables associated with suppliers choosing to voluntarily participate in the Programs were presented as accounts payable within Total current liabilities on the Consolidated Balance Sheets, and totaled $179 million and $170 million as of March 31,

2021 and December 31, 2020, respectively. The amounts paid that are associated with suppliers once they chose to voluntarily participate in the Programs for the three months ended March 31, 2021 and 2020 were $114 million, and $93 million, respectively, with all activity related to the obligations presented within operating activities on the Consolidated Statements of Cash Flows.

The desire of suppliers and financial institutions to participate in the Programs could be negatively impacted by, among other factors, the availability of capital committed by the participating financial institutions, the cost and availability of our suppliers’ capital, a credit rating downgrade or deteriorating financial performance of the Company or its participating subsidiaries, or other changes in financial markets beyond our control.We do not expect these risks, or potential long-term growth of our programs, to materially affect our overall financial condition, as we expect a significant portion of our payments to continue to be made outside of the Programs.Accordingly, we do not believe the programs have materially impacted our current period liquidity, and do not believe that the programs are reasonably likely to materially affect liquidity in the future.

Pension Contributions

Please refer to Note 1110 of the Consolidated Financial Statements. The Company expects to contribute ~~between~~ $25 ~~million and $50~~ million in cash to its global pension plans during ~~2020. We will evaluate discretionary pension contributions as we continue to manage liquidity as the COVID-19 pandemic unfolds throughout the remainder of the year.~~2021. Actual contributions to the plans may change as a result of several factors, including changes in laws that impact funding requirements. The ultimate cash flow impact to the Company, if any, of the pension plan liability and the timing of any such impact will depend on numerous variables, including future changes in actuarial assumptions, legislative changes to pension funding laws, and market conditions.

Derivatives

Please refer to Note 54 of the Consolidated Financial Statements.

Fair Value Measurement

Please refer to Notes 54 and 109 of the Consolidated Financial Statements.

Contractual Obligations

In the normal course of business, we enter into contractual obligations to make payments to third parties. During the three months ended March 31, ~~2020,~~2021, there were no material changes to such contractual obligations outside the ordinary course of our business.

SAFETY

Working safely is a condition of employment at Owens Corning. We believe this organization-wide expectation provides for a safer work environment for employees, improves our manufacturing processes, reduces our costs and enhances our reputation. Furthermore, striving to be a world-class leader in safety provides a platform for all employees to understand and apply the resolve necessary to be a high-performing global organization. We measure our progress on safety based on Recordable Incidence Rate (“RIR”) as defined by the United States Department of Labor, Bureau of Labor Statistics. For the three months ended March 31, ~~2020,~~2021, our RIR was ~~0.47~~0.64 as compared to ~~0.75~~0.56 in the same period a year ago.

~~CRITICAL ACCOUNTING ESTIMATES~~

~~Impairment of Assets~~. The Company exercises judgment in evaluating assets for impairment. Goodwill and other indefinite-lived intangible assets are tested for impairment annually, or when circumstances arise which could more likely than not reduce the fair value of a reporting unit below its carrying value. These tests require comparing recorded values to estimated fair values for the assets under review.

Our reporting units represent a business for which discrete financial information is available and segment management regularly reviews the operating results. The Company has three reporting units: Composites, Insulation and Roofing.

~~Table of Contents~~

~~- 42 -~~

~~ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)~~

In the first quarter of 2020, the Company performed its ongoing assessment to consider whether events or circumstances had occurred that could more likely than not reduce the fair value of a reporting unit below its carrying value. The valuation limitation from the Company’s recent share price decline, the narrow cushion on the Insulation reporting unit and the high level of near-term macroeconomic uncertainty caused the Company to perform an interim goodwill impairment test as of March 31, 2020 over the Insulation reporting unit. After evaluating and weighing all relevant events and circumstances, and considering the substantial excess fair values for these reporting units, we concluded that it is not more likely than not that the fair value of the Roofing and Composites reporting units were less than their carrying values. Consequently, we determined that it was not necessary to perform an interim impairment test for the Roofing and Composites reporting units.

As part of our quantitative testing process for goodwill of the Insulation reporting unit, we estimated fair values using a discounted cash flow analysis, a form of the income approach, from the perspective of a market participant. Significant assumptions used in the discounted cash flow analysis are revenue growth rates and EBIT margins used in estimating discrete period cash flow forecasts of the reporting unit, the discount rate, and the long-term revenue growth rate and EBIT margins used in estimating the terminal business value. For our interim test, the cash flow forecasts of the reporting unit are based upon management’s near-term and long-term views of our markets and represent the forecasts used by senior management and the Board of Directors to operate the business during the COVID-19 pandemic and evaluate operating performance. The discount rate utilized is management’s estimate of what the market’s weighted average cost of capital is for a company with a similar debt rating and stock volatility, as measured by beta, which includes an additional risk premium due to uncertainty surrounding the level and pace of economic recovery. The terminal business value is determined by applying the long-term growth rate to the latest year for which a forecast exists. At this time, the Company believes that the Insulation reporting unit’s long-term market-size and profitability outlook have not meaningfully deteriorated since the time of our most recent annual impairment test. The overall enterprise fair value of the Company was limited by the recent decline in our share price. The reduction in fair value of the Insulation reporting unit, and corresponding impairment charge, was primarily driven by an increase in the discount rate arising from higher equity risk premiums that reflect significant uncertainty surrounding the effect that the COVID-19 pandemic will have on the reporting unit’s near-term cash flows and a decrease in the reporting unit's forecasted near-term cash flows. As part of our goodwill quantitative testing process, the Company evaluates whether there are reasonably likely changes to management’s estimates that would have a material impact on the results of the goodwill impairment testing. Please refer to Note 6 of the Consolidated Financial Statements for additional details on the impairment charge that was recorded in the first quarter of 2020.

The following table summarizes the segment allocation of recorded goodwill on our Consolidated Balance Sheets as of December 31, 2019 and, after giving effect to an impairment charge in our Insulation reporting unit, as of March 31, 2020 (in millions):

Segment March 31, 2020 Percent of Total December 31, 2019 Percent of Total
Composites $ 56 6 % $ 57 3 %
Insulation 508 53 % 1,479 77 %
Roofing 395 41 % 396 20 %
Total goodwill $ 959 100 % $ 1,932 100 %

There continues to be uncertainty surrounding the macroeconomic factors for the Insulation reporting unit, and a sustained downturn, significantly extended recovery, or a change in the long-term revenue growth or profitability for this reporting unit could increase the likelihood of an additional future impairment. Additionally, changes in market participant assumptions such as an increased discount rate or further share price reductions could increase the likelihood of a future impairment.

~~- 43 -~~

~~ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)~~

Other indefinite-lived intangible assets are the Company’s trademarks. Our most recent annual test of indefinite-lived intangibles was conducted as of October 1, 2019. The fair value of each of our indefinite-lived intangible assets was in excess of its carrying value and thus, no impairment existed. The fair value of these assets substantially exceeded the carrying value as of the date of that assessment.

During the first quarter of 2020, we performed an interim impairment test on certain trademarks and trade names used by our Insulation segment. Fair values used in testing for potential impairment of our trademarks are calculated by applying an estimated market value royalty rate to the forecasted revenues of the businesses that utilize those assets. The assumed cash flows from this calculation are discounted at a rate based on a market participant discount rate, which includes a risk premium due to the near-term economic uncertainty from the COVID-19 pandemic and its impact on the projected revenue derived from the trademarks. For two assets used by our Insulation segment, the reduction in fair values, and corresponding impairment charges, were driven by a lower expected sales outlook, the compounding effect of lower expected sales following an immaterial divestiture in the first quarter of 2020 and a higher discount rate associated with the near-term economic uncertainty from the COVID-19 pandemic. Please refer to Note 6 of the Consolidated Financial Statements for additional details on the impairment charges that were recorded in the first quarter of 2020.

For all other indefinite-lived intangible assets used by Insulation and our other segments, we continued to perform our ongoing analysis to consider whether changes in circumstances indicated that it was more likely than not that these assets were impaired. After evaluating and weighing all relevant events and circumstances, and considering the substantial excess fair values for these assets, we concluded that it is not more likely than not that the fair values of these indefinite-lived intangible assets were less than their carrying amounts. Consequently, we determined that it was not necessary to perform an interim impairment test for all other indefinite-lived intangible assets.

~~There were no changes to the recoverability conclusions for our long-lived assets disclosed in our 2019 Form-10-K.~~

Changes in management intentions, market conditions, operating performance and other similar circumstances could affect the assumptions used in these impairment tests. Changes in the assumptions could result in impairment charges that could be material to our Consolidated Financial Statements in any given period.

PART II

ITEM 1. LEGAL PROCEEDINGS

Information required by this item is incorporated by reference to Note 1211 of the Consolidated Financial Statements, Contingent Liabilities and Other Matters.

ITEM 1A. RISK FACTORS

~~The information set forth in this report, including without limitation, the risk factor presented below, updates and should be read in conjunction with,~~There have been no material changes to the risk factors ~~and information~~ disclosed in ~~Part 1,~~ Item ~~1A., "Risk Factors," in our Annual Report on Form 10-K for the year ended December 31, 2019.~~

~~The recent COVID-19 pandemic is expected to have a significant impact on the Company's operations and results.~~

~~Beginning in the first quarter of 2020, we have been managing matters related to the global COVID-19 pandemic, including the following impacts:~~

•~~We believe that COVID-19 has placed downward pressure on demand for some of our products, on at least a temporary basis.~~

•Governmental authorities have implemented numerous measures to contain the virus, such as travel bans and restrictions, quarantines, shelter-in-place orders and business shutdowns. A small number of our facilities and operations have been adversely affected by these governmental actions.

•These governmental actions as well as downward pressure on demand have caused us to curtail some production as we comply with relevant government decrees and attempt to balance demand with inventory and output.

•We have recorded an impairment to goodwill that was driven, at least in part, by an increase in the discount rate arising from higher equity risk premiums that reflect significant uncertainty surrounding the effect that COVID-19 will have on the Insulation reporting unit’s near-term cash flows.

•~~The Company has continued to focus on reducing costs, minimizing capital expenditures and managing working capital during the COVID-19 pandemic.~~

In response to the pandemic, we implemented a number of precautionary and other measures to promote business continuity. These measures have been comprehensive and included initiatives regarding employee health and safety, working conditions (including remote working), engagements with customers and suppliers, financial management, operational efficiency, internal and external communications, government relations and community outreach. While we believe that all of these measures have been necessary or appropriate, they have resulted in additional costs and may adversely impact our business and financial performance in the future or expose us to additional unknown risks.

Although it is not possible to predict the ultimate impact of COVID-19, including on our business, results of operations, financial position or cash flows, such impacts may be material and may include:

•~~shifting customer demand for our products in the markets that we serve around the world;~~

•~~increased credit risk, including increased failure by customers experiencing business disruptions to make timely payments;~~

•~~reduced availability and productivity of employees;~~

•~~costs associated with production curtailments that are driven by governmental actions, customer demand or other causes related to COVID-19;~~

•increased operational risks resulting from changes to operations and remote work arrangements, including the potential effects on internal controls and procedures, cybersecurity risks and increased vulnerability to security breaches, information technology disruptions and other similar events;

•higher costs in certain areas such as transportation and distribution, as well as incremental costs associated with health screenings, temperature checks and enhanced cleaning and sanitation protocols to protect our employees and others;

•~~delays and disruptions in the availability of and timely delivery of materials and equipment used in our operations, as well as increased costs for such materials and equipment;~~

•~~a negative impact on our liquidity position, as well as increased costs and less ability to access funds under our existing credit facilities and the capital markets;~~

•~~any further impairment in the value of tangible or intangible assets that could be recorded as a result of weaker or more volatile economic conditions; and~~

•~~administrative proceedings, litigation or regulatory compliance matters.~~
