NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

1.    GENERAL

Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in this report refer to Owens Corning, a Delaware corporation, and its subsidiaries.

The Consolidated Financial Statements included in this report are unaudited, pursuant to certain rules and regulations of the Securities and Exchange Commission, and include, in the opinion of the Company, normal recurring adjustments necessary for a fair statement of the results for the periods indicated, which, however, are not necessarily indicative of results which may be expected for the full year. The December 31, 2021 balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States ("U.S."). In connection with the Consolidated Financial Statements and Notes included in this report, reference is made to the Consolidated Financial Statements and Notes contained in the Company’s Form 10-K for the year ended December 31, 2021 (the "2021 Form 10-K"). Certain reclassifications have been made to the periods presented for 2021 to conform to the classifications used in the periods presented for 2022.

Revenue Recognition

As of December 31, 2021, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $76 million, of which $15 million was recognized as revenue in the first six months of 2022. As of June 30, 2022, our contract liability balances totaled $82 million.

Cash, Cash Equivalents and Restricted Cash

On the Consolidated Statements of Cash Flows, the total of Cash, cash equivalents and restricted cash includes restricted cash of $7 million as of June 30, 2022, December 31, 2021, June 30, 2021 and December 31, 2020. Restricted cash primarily represents amounts received from a counterparty related to its performance assurance on an executory contract, which is included in Other current assets on the Consolidated Balance Sheets. These amounts are contractually required to be set aside, and the counterparty can exchange the cash for another form of performance assurance at its discretion.

Related Party Transactions

In the first quarter of 2021, a related party relationship was established as a result of a member of the Company’s Board of Directors being named an executive officer of one of the Company’s preexisting suppliers. The related party transactions with this supplier consist of the purchase of raw materials. Purchases from the related party supplier were $39 million and $60 million for the three and six months ended June 30, 2022, respectively, and $27 million and $47 million for the three and six months ended June 30, 2021, respectively.. As of June 30, 2022 and December 31, 2021, amounts due to the related party supplier were $10 million and $1 million, respectively.

Leases

During the first quarter of 2021, the Company entered into a lease for a to-be-constructed warehouse located near our manufacturing facility in Fort Smith, Arkansas. During the second quarter of 2022, construction was completed, and the lease period commenced, resulting in a finance lease right-of-use asset and corresponding lease liability of $35 million being recognized. At no point during the construction period did the Company control the underlying asset as defined in Accounting Standards Codification (ASC) 842 (Leases).

4.    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 June 30, 2022 and December 31, 2021, 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.

The following table presents the fair value of derivatives and hedging instruments and the respective location on the Consolidated Balance Sheets (in millions):

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 June 30, 2022, the notional amounts of these natural gas forward swaps was 9 million MMBtu (or MMBtu equivalent) based on U.S. and European indices.

4.    DERIVATIVE FINANCIAL INSTRUMENTS (continued)

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 this agreement upon a future issuance of 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.

In June 2021, the Company entered into five currency forward contracts with unrelated counterparties totaling $23 million to mitigate against unwanted or anticipated moves in the European Euro exchange rate against the U.S. Dollar, pertaining to forecasted Euro denominated invoices for capital expenditures. The Company has designated each of the individual contracts as cash flow hedges, with the last hedge maturing no later than December 2023.

Net Investment Hedges

The Company has translation exposure resulting from translating the financial statements of foreign subsidiaries into U.S. Dollars, which is recognized in Currency translation adjustment (a component of AOCI). In the second quarter of 2022, the Company terminated the remaining cross-currency forward contracts related to the hedged portions of the net investment in foreign subsidiaries, resulting in cash proceeds of $11 million.

Other Derivatives

The Company uses forward currency exchange contracts to manage existing exposures to foreign exchange risk related to assets and liabilities recorded on the Consolidated Balance Sheets. As of June 30, 2022, the Company had notional amounts of $705 million for non-designated derivative financial instruments related to foreign currency exposures in U.S. Dollars primarily related to Brazilian Real, Chinese Yuan, European Euro, Hong Kong Dollar, Indian Rupee, and South Korean Won. In addition, the Company had notional amounts of $7 million for non-designated derivative financial instruments related to foreign currency exposures in European Euro primarily related to the Norwegian Krone and Polish Złoty.

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 six months of 2022. The changes in the net carrying value of goodwill by segment are as follows (in millions):

	Composites		Insulation		Roofing		Total

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.

Other intangible assets consist of the following (in millions):

Accumulated depreciation	(3,373)		(3,341)
Property, plant and equipment, net	$	3,684	$	3,873

Machinery and equipment includes certain precious metals used in our production tooling, which comprise approximately 10% of total machinery and equipment as of both June 30, 2022 and December 31, 2021. Precious metals used in our production tooling are depleted as they are consumed during the production process, which typically represents an annual expense of about 3% of the outstanding carrying value.

Our production tooling needs in our Composites segment are changing in response to economic and technological factors. As a result, we exchanged certain precious metals used in production tooling for certain other precious metals to be used in production tooling. These non-cash investing activities are not included in Net cash flow used for investing activities in the Consolidated Statements of Cash Flows. During the three and six months ended June 30, 2022, these non-cash exchanges resulted in a net increase to Machinery and equipment of $7 million and $11 million, respectively, and gains totaling $7 million and $11 million, respectively. During the three and six months ended June 30, 2021, these non-cash exchanges resulted in a net increase to Machinery and equipment of $21 million and $41 million, respectively, and gains totaling $21 million and $41 million, respectively. The gains are included in Other expense (income), net on the Consolidated Statements of Earnings and are reflected in the Corporate, Other and Eliminations reporting category. We do not expect these exchanges to materially impact our current or future capital expenditure requirements or rate of depletion.

7.    ACQUISITIONS

On May 23, 2022, Owens Corning and Pultron Composites ("Pultron") formed a joint venture ("JV") to manufacture and sell fiberglass rebar. The Company contributed approximately $47 million to acquire a 65.5% controlling interest and has established a redeemable noncontrolling interest related to Pultron, the minority holder. The JV expands Owens Corning’s capability to produce high-value material solutions by combining the Company’s glass-fiber material technology, channel access and extensive industry experience with Pultron’s manufacturing expertise and process efficiency. The fully consolidated operating results and a preliminary purchase price allocation for the JV have been included in the Company’s Composites segment within the Consolidated Financial Statements since the date of the formation of the JV. Subsequent to the JV formation, the JV acquired assets and technology from Pultron for approximately $65 million. The purchase price allocation is preliminary and resulted in the recognition of $15 million in intangible assets, consisting of technology, with an estimated weighted average life of 15 years and $42 million in goodwill. The pro-forma effect of this acquisition on revenues and earnings was not material.

On June 1, 2022, the Company acquired all of the outstanding assets of WearDeck®, a premium producer of composite weather-resistant decking for commercial and residential applications, for approximately $133 million, net of cash acquired. The acquisition advances the Composites business growth strategy to focus on high-value material solutions within the building and construction industry. The operating results and a preliminary purchase price allocation for WearDeck® have been included in the Composites segment within the Consolidated Financial Statements since the date of the acquisition. The purchase price allocation is preliminary and resulted in the recognition of $38 million in intangible assets and $70 million in goodwill. The intangible assets consist of indefinite-lived trademarks of $7 million, technology of $10 million with an estimated weighted average life of 11 years and customer relationships of $21 million with an estimated weighted average life of 15 years. The pro-forma effect of this acquisition on revenues and earnings was not material.

On June 15, 2022, Owens Corning signed an agreement to acquire Natural Polymers, LLC, an innovative manufacturer of spray polyurethane foam insulation for building and construction applications. The transaction has cleared regulatory approvals and other customary conditions and is anticipated to close in the third quarter of 2022.

ACQUISTION-RELATED COSTS

In the second quarter of 2022, the Company incurred $3 million of transaction costs related to its announced acquisitions. Please refer to Note 7 of the Consolidated Financial Statements for further information regarding these acquisitions.

RESTRUCTURING RELATED-COSTS

Exit of DUCS Product Line

In May 2022, the Company exercised the put option for the sale of the European portion of the DUCS product line located in Chambéry, France, within the Composite's segment. As a result, the Company recorded a pre-tax charge of $29 million in Other expense (income), net on the Consolidated Statements of Earnings to reflect the fair value less cost to sell of the assets. Please refer to Note 8 of the Consolidated Financial Statements for further information. The Company also took decisions to convert the DUCS manufacturing facilities located in Anderson, South Carolina and Kimchon, Korea to produce other glass fiber products needed to support our growth strategy in building and construction applications. As a result, the Company recorded $2 million of non-cash charges in the second quarter, primarily related to accelerated depreciation for equipment at the Anderson, South Carolina facility and $1 million of cash charges primarily related to retention. The Company does not expect to recognize significant incremental costs related to these actions.

Roofing Restructuring Actions

In December 2021, the Company took actions to restructure operations within the Roofing segment's components product line by relocating production assets from China to India which will allow the business to optimize its manufacturing network and support a tariff mitigation strategy. During the first six months of 2022, the Company recorded less than $1 million of charges primarily related to accelerated depreciation and severance. The Company expects to recognize $7 million of incremental charges related to these actions in 2022.

Santa Clara Insulation Site

During the third quarter of 2021, the Company entered into a purchase and sale agreement for the Company's Insulation site in Santa Clara, California. The Company expects to continue operations at this facility through early fourth quarter of 2022 and complete the transaction in the first quarter of 2023. This action is part of the Company's on-going strategy to operate a flexible, cost-efficient manufacturing network and geographically locate its assets to better service its customers. Cumulative cash pre-tax charges associated with the transaction are expected to be in the range of $30 million to $40 million, primarily related to severance and one-time employee termination benefits, demolition costs, and other closing costs. In addition, cumulative non-cash charges are expected to be in the range of $75 million to $85 million, primarily consisting of accelerated depreciation of property, plant and equipment and derecognition of the carrying value of land, which will offset the gross proceeds at closing.

During the first six months of 2022, the Company recorded $13 million of charges, primarily related to accelerated depreciation, associated with this agreement.

2020 Insulation Restructuring Actions

During the fourth quarter of 2020, the Company took actions to avoid future capital outlays and reduce costs in its global Insulation segment, mainly through decisions to close certain manufacturing facilities in Shanghai, China and Fresno, Texas, and optimize a facility in Parainen, Finland. During the first six months of 2022, the Company recorded $1 million of charges primarily related to accelerated depreciation. The Company does not expect to recognize significant incremental costs related to these actions.

In the first quarter of 2022, the Company recognized a gain of $27 million in Other expense (income), net on the Consolidated Statements of Earnings, associated with the sale of the manufacturing facility in Shanghai, China.

Acquisition-Related Restructuring

Following the acquisitions of Paroc Group Oy ("Paroc") and Pittsburgh Corning Corporation and Pittsburgh Corning Europe NV (collectively, "Pittsburgh Corning") into the Company's Insulation segment, the Company took actions to realize expected synergies from the newly acquired operations. The Company does not expect to recognize significant incremental costs related to these actions.

Collectively, the senior notes above are referred to as the “Senior Notes.” The Senior Notes are general unsecured obligations of the Company and rank pari passu with all existing and future senior unsecured indebtedness of the Company.

The Company has the option to redeem all or part of the Senior Notes at any time at a “make-whole” redemption price. The Company is subject to certain covenants in connection with the issuance of the Senior Notes that it believes are usual and customary. The Company was in compliance with these covenants as of June 30, 2022.

Senior Revolving Credit Facility

The Company has an $800 million senior revolving credit facility (the "Senior Revolving Credit Facility") with a maturity date in July 2026 that includes both borrowings and letters of credit. Borrowings under the Senior Revolving Credit Facility may be used for general corporate purposes and working capital. The Company has the discretion to borrow under multiple options, which provide for varying terms and interest rates including the United States prime rate, federal funds rate plus a spread or LIBOR plus a spread. The current agreement also includes fallback language related to a benchmark reference rate replacement, when a LIBOR transition occurs.

In June 2022, the Senior Revolving Credit Facility was amended to allow the Company to continue to operate in comprehensively sanctioned countries so long as it is not violating any sanctions.

The Senior Revolving Credit Facility contains various covenants, including a maximum allowed leverage ratio, that the Company believes are usual and customary for a senior unsecured credit agreement. The Company was in compliance with these covenants as of June 30, 2022. Please refer to the Credit Facility Utilization section below for liquidity information as of June 30, 2022.

Receivables Securitization Facility

12.    PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS

Pension Plans

The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employees' 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 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. 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.

The following table provides information regarding pension expense recognized (in millions):

13.    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 June 30, 2022, the Company was involved with a total of 23 sites worldwide, including 10 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 reasonably estimates the costs of remediation to be paid over a period of years. The Company accrues an amount on an undiscounted basis, when a liability is probable and reasonably estimable. Actual cost may differ from these estimates for the reasons mentioned above. At June 30, 2022, the Company had an accrual totaling $6 million for these costs, of which the current portion is $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.

14.    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 share awards. At June 30, 2022, the number of shares remaining available under the 2019 Stock Plan for all stock awards was approximately 2.7 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 is as follows (in millions):

	Three Months Ended<br>June 30,				Six Months Ended<br>June 30,
	2022		2021		2022		2021
Total stock-based compensation expense	$	13	$	12	$	25	$	24

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 June 30, 2022, there was no unrecognized compensation cost related to stock options and the range of exercise prices on outstanding stock options was $37.65 - $42.16.

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

		Weighted-Average
	Number of<br><br>Options	Exercise Price		Remaining <br>Contractual Life <br>(in years)	Intrinsic Value (in millions)
Outstanding, December 31, 2021	55,900	$	39.34	1.71	$	3
Exercised	(4,800)	41.03
Outstanding, June 30, 2022	51,100	$	39.19	1.26	$	2

14.    STOCK COMPENSATION (continued)

Restricted Stock Units

The Company has granted restricted stock units (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 2022 was $91.12.

The following table summarizes the Company’s RSU plans:

	Number of RSUs	Weighted-Average<br>Fair Value
Balance at December 31, 2021	1,268,993	$	62.25
Granted	340,927	91.12
Vested	(299,440)	67.70
Forfeited	(35,582)	74.48
Balance at June 30, 2022	1,274,898	$	68.23

As of June 30, 2022, there was $45 million of total unrecognized compensation cost related to RSUs. That cost is expected to be recognized over a weighted-average period of 2.52 years. The total grant date fair value of shares vested during the six months ended June 30, 2022 and 2021 was $20 million and $24 million, respectively.

Performance Share Units

The Company has granted performance share units (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 six months ended June 30, 2022, 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 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.

Grant date fair value of units granted	$	122.69

The risk-free interest rate was based on zero-coupon United States Treasury bills at the grant date. The expected term represents the period from the grant date to the end of the three-year performance period.

PSU Summary

As of June 30, 2022, there was $27 million total unrecognized compensation cost related to PSUs. That cost is expected to be recognized over a weighted-average period of 1.90 years.

The following table summarizes the Company’s PSU activity:

	Number<br>of PSUs	Weighted-Average<br>Grant-Date<br>Fair Value

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. 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 June 30, 2022, 3.7 million shares remain available for purchase.

Included in total stock-based compensation expense is $2 million and $3 million of expense related to the Company's ESPP recognized during the three and six months ended June 30, 2022, respectively. During the three and six months ended June 30, 2021, the Company recognized expense of $2 million and $3 million, respectively, related to the Company's ESPP. As of June 30, 2022, there was $2 million of total unrecognized compensation cost related to the ESPP.

For the three and six months ended June 30, 2022 and June 30, 2021, there were no non-vested restricted or performance shares that had an anti-dilutive effect on earnings per share.

On February 14, 2022, the Board of Directors approved a new 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 will be at the Company's discretion. The Company repurchased 3.5 million shares of its common stock for $315 million during the six months ended June 30, 2022, under the Repurchase Authorization. As of June 30, 2022, 9.9 million shares remain available for repurchase under the Repurchase Authorization.

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 global building and construction materials leader helping customers win in the market by providing innovative and sustainable solutions. The Company has three reporting segments: Composites, Insulation and Roofing. Through these lines of business, the Company manufactures and sells products worldwide. We maintain leading market positions in many of our major product categories.

EXECUTIVE OVERVIEW

Net earnings attributable to Owens Corning were $343 million in the second quarter of 2022, compared to $298 million in the same period of 2021. The Company reported $489 million in earnings before interest and taxes ("EBIT") for the second quarter of 2022 compared to $428 million in the same period of 2021. The Company generated $525 million in adjusted earnings before interest and taxes (“Adjusted EBIT”) for the second quarter of 2022 compared to $408 million in the same period of 2021. 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 attributable to Owens Corning. Second quarter of 2022 EBIT performance compared to the same period of 2021 increased $56 million, $45 million, and $24 million in our Composites, Insulation, and Roofing segments, respectively. Within our Corporate, Other and Eliminations category, General corporate expense and other increased by $8 million.

Cash and cash equivalents were $810 million as of June 30, 2022, compared to $888 million as of June 30, 2021 as a result of increased cash outflows from investing and financing activities, partially offset by higher earnings. In the six months ended June 30, 2022, the Company's operating activities provided $624 million of cash flow, compared to $702 million in the same period in 2021 due to an increase in operating assets, specifically receivables and inventory, in 2022 compared to the same period of 2021.

As the Russian invasion of Ukraine evolves, we continue to closely monitor the potential impact on our businesses and our people. We believe that we have taken the necessary steps to ensure compliance with applicable regulatory restrictions on international trade and financial transactions associated with our Russian businesses. In late March, we announced our intent to exit Russia through a transfer or sale of our facilities. We are working to expedite our exit, while remaining committed to the safety and security of our employees in the region. Net sales from our Russian operations and its associated assets represent approximately 1% of annual consolidated net sales and consolidated assets, respectively.

On July 15, 2022, Owens Corning entered into a legally binding agreement to acquire the remaining 50% interest in Fiberteq. The acquisition is anticipated to close in the third quarter of 2022.

On June 15, 2022, Owens Corning signed an agreement to acquire Natural Polymers, LLC, an innovative manufacturer of spray polyurethane foam insulation for building and construction applications. The transaction has cleared regulatory approvals and other customary conditions and is anticipated to close in the third quarter of 2022.

On June 1, 2022, the Company acquired all of the outstanding assets of WearDeck®, a premium producer of composite weather-resistant decking for commercial and residential applications, for approximately $133 million, net of cash acquired. The acquisition advances the Composites business growth strategy to focus on high-value material solutions within the building and construction industry. The operating results and a preliminary purchase price allocation for WearDeck® have been included in the Composites segment within the Consolidated Financial Statements since the date of the acquisition. The purchase price allocation is preliminary and resulted in the recognition of $38 million in intangible assets and $70 million in goodwill. The intangible assets consist of indefinite-lived trademarks of $7 million, technology of $10 million with an estimated weighted average life of 11 years and customer relationships of $21 million with an estimated weighted average life of 15 years.

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

On May 23, 2022, Owens Corning and Pultron formed a JV to manufacture and sell fiberglass rebar. The Company contributed approximately $47 million to acquire a 65.5% controlling interest and has established a redeemable noncontrolling interest related to Pultron, the minority holder. The JV expands Owens Corning’s capability to produce high-value material solutions by combining the Company’s glass-fiber material technology, channel access and extensive industry experience with Pultron’s manufacturing expertise and process efficiency. The fully consolidated operating results and a preliminary purchase price allocation for the JV have been included in the Company’s Composites segment within the Consolidated Financial Statements since the date of the formation of the JV. Subsequent to the JV formation, the JV acquired assets and technology from Pultron for approximately $65 million. The purchase price allocation is preliminary and resulted in the recognition of $15 million in intangible assets, consisting of technology, with an estimated weighted average life of 15 years and $42 million in goodwill.

On May 16, 2022, the Company exercised the put option for the sale of the European portion of the DUCS product line located in Chambéry, France, within the Composite's segment. The Company recorded a pre-tax charge of $29 million in Other expense (income), net on the Consolidated Statements of Earnings to reflect fair value less cost to sell of these assets. Assets held for sale as of June 30, 2022 were $81 million and primarily consisted of property, plant and equipment. On July 1, 2022, the Company closed on the sale of the European portion of the DUCS product line located in Chambéry, France.

On February 14, 2022, the Board of Directors approved a new 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 Company repurchased 1.0 million shares of its common stock for $86 million in the second quarter of 2022 under the Repurchase Authorization. As of June 30, 2022, 9.9 million shares remained available for repurchase under the Repurchase Authorization.

The Consolidated Results discussion below provides a summary of our results and the trends affecting our business, and should be read in conjunction with the more detailed Segment Results discussion that follows.

NET SALES

In the second quarter and year-to-date 2022, net sales increased $362 million and increased $793 million, respectively, compared to the same periods in 2021. For the second quarter and year-to-date, the increase in net sales was driven by higher selling prices and favorable customer mix which were partially offset by lower sales volumes and the unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

GROSS MARGIN

In the second quarter and year-to-date 2022, gross margin increased $116 million and increased $291 million, respectively, compared to the same periods in 2021 driven by higher selling prices, partially offset by higher input cost inflation and transportation costs in all three segments.

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

MARKETING AND ADMINISTRATIVE EXPENSES

In the second quarter and year-to-date 2022, marketing and administrative expenses increased $13 million and increased $23 million, respectively, compared to the same periods in 2021 driven primarily by higher general corporate expenses as business activities return to a more typical, post-pandemic level.

OTHER EXPENSE (INCOME), NET

In the second quarter and year-to-date 2022, other expenses increased $39 million and increased $59 million, respectively, compared to the same periods in 2021. For the second quarter, the increase was driven primarily by the $29 million impairment loss on the Chambéry, France assets held for sale. For year-to-date, the increase was primarily driven by the $29 million impairment loss on the Chambéry, France assets held for sale and lower gains on sale of certain precious metals of $30 million. The $27 million gain on sale of the Shanghai, China facility was offset by the comparison year-over-year to the $27 million of gains on settlements from contracts to purchase and sell wind-generated electricity in the same period in 2021.

INTEREST EXPENSE, NET

In the second quarter and year-to-date 2022, interest expense, net, decreased $7 million and decreased $12 million, respectively, compared to the same periods in 2021. The decrease was driven by lower long-term debt balances year over year due to the repayment of the senior notes due in 2022 and higher interest income.

INCOME TAX EXPENSE

Income tax expense for the three and six months ended June 30, 2022 was $119 million and $226 million, respectively. For the second quarter of 2022, the Company's effective tax rate was 26% and for the six months ended June 30, 2022, the Company's effective tax rate was 26%. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended June 30, 2022 is primarily due to U.S. state and local income tax expense, U.S. federal taxes on foreign earnings, foreign rate differential and other discrete adjustments. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the six months ended June 30, 2022 is primarily due to U.S. state and local income tax expense, U.S. federal taxes on foreign earnings, foreign rate differential 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 not 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.

Income tax expense for the three and six months ended June 30, 2021 was $97 million and $156 million. For the second quarter of 2021, the Company's effective tax rate was 25% and for the six months ended June 30, 2021 the Company's effective tax rate was 24%. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended June 30, 2021 is primarily due to U.S. state and local income tax expense, U.S. federal taxes on foreign earnings, 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 six months ended June 30, 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.

Restructuring, Acquisition and Divestiture-Related Costs

The Company has incurred restructuring, transaction and integration costs related to acquisitions and divestitures, along with restructuring and other exit costs in connection with its global cost reduction and productivity initiatives and Company's growth strategy. These costs are recorded within Corporate, Other and Eliminations. Please refer to Note 10 of the Consolidated Financial Statements for further information on the nature of these costs.

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 attributable to Owens Corning as prepared in accordance with accounting principles generally accepted in the United States.

Adjusting income (expense) items to EBIT are shown in the table below (in millions):

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.

Composites

The table below provides a summary of net sales, EBIT and depreciation and amortization expense for the Composites segment (in millions):

	Three Months Ended<br>June 30,						Six Months Ended<br>June 30,
	2022			2021			2022			2021
Net sales	$	719		$	583		$	1,433		$	1,142

EBIT as a % of net sales	21		%	17		%	21		%	15		%
Depreciation and amortization expense	$	48		$	39		$	91		$	77

NET SALES

In our Composites segment, net sales in the second quarter of 2022 increased $136 million compared to the same period in 2021. The increase was primarily driven by higher selling prices of $131 million. Favorable customer mix of $14 million and the $13 million impact of the acquisition of vliepa GmbH in July 2021 were partially offset by the $18 million unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

For year-to-date 2022, net sales in our Composites segment increased $291 million compared to the same period in 2021. The increase was driven by higher selling prices of $261 million. Favorable customer mix of $42 million and the acquisition of vliepa GmbH in July 2021 were partially offset by the $34 million unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

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

EBIT

In our Composites segment, EBIT in the second quarter of 2022 increased $56 million compared to the same period in 2021. Higher selling prices of $131 million and favorable customer mix more than offset $50 million of input cost inflation and $14 million in higher transportation costs. The remaining variance was driven by unfavorable manufacturing performance and other one-time charges.

For the year-to-date 2022, EBIT in our Composites segment increased $131 million compared to the same period in 2021. Higher selling prices of $261 million and favorable customer mix more than offset $103 million of input cost inflation and $24 million in higher transportation costs. The remaining variance was driven by unfavorable manufacturing performance and other one-time charges.

OUTLOOK

Global glass reinforcements market demand has several economic indicators including residential, non-residential construction and manufacturing production indices, as well as global wind installations. The Company anticipates relatively stable market conditions, with continued input cost inflation, supply chain uncertainties and primary labor availability. The Russian invasion of Ukraine is creating uncertainty in global markets and putting further pressure on already-fragile global supply chains. The Company is closely monitoring the evolving situation and remains focused on managing costs, capital expenditures, and working capital.

Insulation

The table below provides a summary of net sales, EBIT and depreciation and amortization expense for the Insulation segment (in millions):

	Three Months Ended<br>June 30,						Six Months Ended<br>June 30,
	2022			2021			2022			2021
Net sales	$	934		$	806		$	1,793		$	1,506
% change from prior year	16		%	35		%	19		%	26		%

EBIT as a % of net sales	17		%	14		%	16		%	13		%
Depreciation and amortization expense	$	51		$	53		$	104		$	104

NET SALES

In our Insulation segment, net sales in the second quarter of 2022 increased $128 million compared to the same period in 2021. The increase was driven by higher selling prices of $142 million partially offset by slightly lower sales volumes. Favorable customer and product mix were offset by the $31 million unfavorable impact of translating sales denominated in foreign currencies into United States dollars

For year-to-date 2022, net sales in our Insulation segment increased $287 million compared to the same period in 2021. The increase was driven by higher selling prices of $259 million and slightly higher sales volumes. Favorable customer and product mix were offset by the $46 million unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

EBIT

In our Insulation segment, EBIT in the second quarter of 2022 increased $45 million compared to the same period in 2021. Higher selling prices of $142 million and favorable customer mix more than offset $82 million of input cost inflation, $15 million in higher transportation costs and higher selling, general and administrative expenses.

Table of Contents

- 42 -

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

For the year-to-date 2022, EBIT in our Insulation segment increased $92 million compared to the same period in 2021. Higher selling prices of $259 million, higher sales volumes and favorable customer mix more than offset $157 million of input cost inflation, $29 million in higher transportation costs and higher selling, general and administrative expenses.

OUTLOOK

The outlook for Insulation demand is driven by North American new residential construction, remodeling and repair activity, as well as commercial and industrial construction activity in the United States, Canada, Europe, Asia-Pacific and Latin America. 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. Demand for residential insulation is most closely correlated to U.S. housing starts.

During the second quarter of 2022, the average Seasonally Adjusted Annual Rate (SAAR) of U.S. housing starts was approximately 1.652 million, up from an annual average of approximately 1.568 million starts in the second quarter of 2021.

The Company expects both the North American new residential construction market and global commercial and industrial construction markets to remain positive, with continued input cost inflation, supply chain uncertainties and primary labor availability. The Russian invasion of Ukraine is creating uncertainty in global markets and putting further pressure on already-fragile global supply chains. The Company is closely monitoring the evolving situation and remains focused on managing costs, capital expenditures, and working capital.

Roofing

The table below provides a summary of net sales, EBIT and depreciation and amortization expense for the Roofing segment (in millions):

	Three Months Ended<br>June 30,						Six Months Ended<br>June 30,
	2022			2021			2022			2021
Net sales	$	1,018		$	917		$	1,856		$	1,628

EBIT as a % of net sales	25		%	26		%	23		%	24		%
Depreciation and amortization expense	$	17		$	14		$	31		$	29

NET SALES

In our Roofing segment, net sales in the second quarter of 2022 increased $101 million compared to the same period in 2021. Higher selling prices of $153 million and higher-third party asphalt sales of $18 million were partially offset by lower sales volumes of approximately 6% and unfavorable product mix.

For year to date 2022, net sales in our Roofing segment increased $228 million compared to the same period in 2021. Higher selling prices of $273 million and higher-third party asphalt sales of $25 million were partially offset by lower sales volumes of approximately 3% and unfavorable product mix.

EBIT

In our Roofing segment, EBIT in the second quarter of 2022 increased $24 million compared to the same period in 2021. Higher selling prices of $153 million more than offset input cost inflation, primarily asphalt, of $92 million, $11 million of higher transportation costs and the impact of lower sales volumes.

Table of Contents

- 43 -

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

For year-to-date 2022, EBIT in our Roofing segment increased $44 million compared to the same period in 2021. Higher selling prices of $273 million more than offset input cost inflation, primarily asphalt, of $161 million and $19 million of higher transportation costs. The impact of selling higher cost inventory, resulting from planned maintenance downtime taken in the fourth quarter of 2021, negatively impacted EBIT by approximately $17 million compared to the same period last year, as significantly less downtime was taken in the fourth quarter of 2020. The remaining variance was driven by the impact of lower sales volumes and higher selling, general and administrative expenses, as the business returns to more normal post-COVID activities.

OUTLOOK

In our Roofing segment, we expect the factors that have driven strong margins in recent years, such as growth from remodeling demand, along with higher sales of roofing components, to continue to deliver profitability. Uncertainties that may impact our Roofing margins include demand from storm and other weather events, demand from new construction, competitive pricing pressure and the cost and availability of raw materials.

Despite strength in the U.S. asphalt shingle market, the Company will continue to evaluate economic factors such as input cost inflation, supply chain uncertainties and primary labor availability. The Company will continue to focus on managing costs, capital expenditures, and working capital.

Corporate, Other and Eliminations

EBIT

In Corporate, Other and Eliminations, EBIT expenses for the second quarter of 2022 were higher by $64 million compared to the same period in 2021, primarily driven by the impairment loss on Chambéry, France assets held for sale, higher restructuring charges and lower gains on sale of certain precious metals. For the year-to-date 2022, EBIT expenses in Corporate, Other and Eliminations were higher by $65 million, primarily driven by the impairment loss on Chambéry, France assets held for sale, higher restructuring charges and lower gains on sale of certain precious metals offset by the gain on the sale of the Shanghai, China facility.

General corporate expense and other for the second quarter 2022 were higher by $8 million compared to the same period in 2021. For year-to-date, general corporate expense and other were higher by $15 million compared to the same period in 2021. For the quarter and year-to-date, the increase was primarily driven by higher general corporate expenses as business activities return to a more typical, post-pandemic level.

OUTLOOK

In 2022, we estimate general corporate expenses to be in the range of $170 million and $180 million.

LIQUIDITY, CAPITAL RESOURCES AND OTHER RELATED MATTERS

Liquidity

The Company's primary sources of liquidity are its balance of Cash and cash equivalents of $810 million as of June 30, 2022, its Senior Revolving Credit Facility and its Receivables Securitization Facility (each as defined below).

The Company has an $800 million senior revolving credit facility (the "Senior Revolving Credit Facility") that has been amended from time to time, which matures in July 2026.

The Company has a $280 million receivables securitization facility (the "Receivables Securitization Facility") that has been amended from time to time, which matures in April 2024.

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

	Balance at June 30, 2022
	Senior Revolving Credit Facility		Receivables Securitization Facility
Facility size or borrowing limit	$	800	$	280
Collateral capacity limitation on availability	N/A		—
Outstanding borrowings	—		—
Outstanding letters of credit	4		1
Availability on facility	$	796	$	279

The Receivables Securitization Facility and Senior Revolving Credit Facility mature in 2024 and 2026, respectively. The Company has no significant debt maturities of senior notes before the fourth quarter of 2024. As of June 30, 2022, the Company had $3.0 billion of total debt and cash and cash equivalents of $810 million. The agreements governing our Senior Revolving Credit Facility and Receivables Securitization Facility contain various covenants that we believe are usual and customary. These covenants include a maximum allowed leverage ratio. We were in compliance with these covenants as of June 30, 2022.

In June 2022, the Senior Revolving Credit Facility was amended to allow the Company to continue to operate in comprehensively sanctioned countries so long as it is not violating any sanctions.

Cash and cash equivalents held by foreign subsidiaries may be subject to foreign withholding taxes upon repatriation to the U.S. As of June 30, 2022, and December 31, 2021, the Company had $227 million and $156 million, respectively, in cash and cash equivalents in certain of our foreign subsidiaries. The Company continues to assert indefinite reinvestment in accordance with Accounting Standards Codification (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 16 of the Risk Factors disclosed in Item 1A of the Company's Form 10-K for the year ended December 31, 2021 (the "2021 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.

Material Cash Requirements

Our anticipated uses of cash include capital expenditures, working capital needs, share repurchases, meeting financial obligations, payments of any dividends authorized by our Board of Directors, acquisitions, restructuring actions and pension contributions. 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 our Receivables Securitization Facility, will provide ample liquidity to enable us to meet our cash requirements.

Please refer to Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations, included in our 2021 Form 10-K for more details on these material cash requirements. During the second quarter of 2022, there have been no material changes to our expected uses of cash and contractual obligations.

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

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 within Accounts payable on the Consolidated Balance Sheets, and totaled $258 million and $226 million as of June 30, 2022 and December 31, 2021, respectively. The amounts paid which are associated with suppliers once they chose to voluntarily participate in the Programs for the six months ended June 30, 2022 and 2021 were $304 million and $235 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.

Cash Flows

The following table presents a summary of our cash balance, cash flows, and availability on credit facilities (in millions):

	Six Months Ended<br>June 30,
		2022		2021
Cash and cash equivalents		$	810	$	888
Net cash flow provided by operating activities		$	624	$	702
Net cash flow used for investing activities		$	(340)	$	(213)
Net cash flow used for financing activities		$	(429)	$	(320)
Availability on the Senior Revolving Credit Facility		$	796	$	796
Availability on the Receivables Securitization Facility		$	279	$	279

Cash and cash equivalents: Cash and cash equivalents as of June 30, 2022 decreased $78 million compared to June 30, 2021 primarily driven by increased cash outflows from investing and financing activities, offset by higher earnings.

Operating activities: For the six months ended June 30, 2022, the Company's operating activities provided $624 million of cash compared to $702 million provided in the same period in 2021. The change in cash provided by operating activities was due to an increase in operating assets, specifically receivables and inventory, in 2022 compared to the same period of 2021.

Investing activities: Net cash flow used for investing activities increased $127 million for the six months ended June 30, 2022 compared to the same period of 2021, primarily driven by higher year-over-year spending on acquisitions.

Financing activities: Net cash used for financing activities was $429 million for the six months ended June 30, 2022, compared to net cash used for financing activities of $320 million in the same period in 2021. The change was primarily due to higher purchases of treasury stock and increase in dividends paid.

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 Incident Rate (“RIR”) as defined by the United States Department of Labor, Bureau of Labor Statistics. For the three months ended June 30, 2022, our RIR was 0.81 as compared to 0.51 in the same period a year ago. For the six months ended June 30, 2022, our RIR was 0.70 compared to 0.58 in the same period a year ago.

Execution Version

This FIRST AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT (this “Amendment”) is dated as of June 13, 2022 and is by and among

(i)    OWENS CORNING, a Delaware corporation (the “Borrower”);

(ii)    the Lenders party to the Credit Agreement which are signatories hereto; and

(iii)    WELLS FARGO BANK, NATIONAL ASSOCIATION, as Administrative Agent (in such capacity, the “Administrative Agent”).

Unless otherwise indicated, all capitalized terms used herein and not otherwise defined herein shall have the respective meanings provided such terms in the Credit Agreement, and when used herein each term defined in Annex I hereto has the same meaning herein as provided therein.

(a)The following defined terms are hereby added to Section 1.1 of the Credit Agreement in the appropriate alphabetical order:

“First Amendment” shall mean the First Amendment to Amended and Restated Credit Agreement dated as of the First Amendment Effective Date by and among the Borrower, the Administrative Agent and the Lenders party thereto.
