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, 2022 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 annual report on Form 10-K for the year ended December 31, 2022 (the “2022 Form 10-K”). Certain reclassifications have been made to the periods presented for 2022 to conform to the classifications used in the periods presented for 2023.

Revenue Recognition

As of December 31, 2022, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $89 million, of which $15 million was recognized as revenue in the first six months of 2023. As of June 30, 2023, our contract liability balances totaled $92 million.

As of December 31, 2021, our contract liability balances 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 $9 million as of June 30, 2023, $8 million as of December 31, 2022, and $7 million as of June 30, 2022 and December 31, 2021. 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 $29 million and $50 million for the three and six months ended June 30, 2023, respectively, and $39 million and $60 million for the three and six months ended June 30, 2022, respectively. As of June 30, 2023 and December 31, 2022, amounts due to the related party supplier were $5 million and $3 million, respectively.

1. GENERAL (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. The Company’s payment terms to the financial institutions, including the timing and amount of payments, are based on the original supplier invoices. One of the 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 Credit Agreement. The obligations are presented as Accounts payable within Total current liabilities on the Consolidated Balance Sheets and all activity related to the obligations is presented within operating activities on the Consolidated Statements of Cash Flow.

The Company’s confirmed outstanding obligations under the Programs totaled $219 million and $234 million as of June 30, 2023 and December 31, 2022, respectively. The amounts of invoices paid under the Programs totaled $307 million and $304 million for the six months ended June 30, 2023 and June 30, 2022, respectively.

Accounting Pronouncements

All Accounting Standards Updates (“ASUs”) recently issued by the Financial Accounting Standards Board (“FASB”) were either not applicable to the Company or their adoption did not have a material impact on the Company’s Consolidated Financial Statements.

EARNINGS BEFORE INTEREST AND TAXES

Earnings before interest and taxes (“EBIT”) by segment consist of net sales less related costs and expenses, and are 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 within Corporate, Other and Eliminations.

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, 2023 and December 31, 2022, 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 and foreign exchange forward contracts, 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):


		Fair Value at
	Location	June 30, 2023		December 31, 2022
Derivative assets designated as hedging instruments:






Cash flow hedges:
Natural gas forward swaps	Other current assets	$	—	$	2


Derivative liabilities designated as hedging instruments:

4. DERIVATIVE FINANCIAL INSTRUMENTS (continued)

In 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. The Company designated this forward U.S. Treasury rate lock agreement, which expired on December 15, 2022, as a cash flow hedge. The locked fixed rate of this agreement was 0.994%. In September 2022, a gain of $6 million was recognized as a result of a change in the forecasted issuance of certain senior notes. In December 2022, the Company received cash of $37 million upon the settlement of the rate lock agreement, of which $31 million will be amortized as a component of interest expense upon the future issuance of senior notes. This unrecognized gain of $31 million was included in AOCI as of June 30, 2023.

Net Investment Hedges

The Company has translation exposure resulting from translating the financial statements of foreign subsidiaries into United States 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, 2023, the Company had notional amounts of $132 million for non-designated derivative financial instruments related to foreign currency exposures in United States Dollars primarily related to the Brazilian Real, Chinese Yuan, Indian Rupee, Hong Kong Dollar, South Korean Won, and Japanese Yen. In addition, the Company had notional amounts of $32 million for non-designated derivative financial instruments related to foreign currency exposures in European Euro primarily related to the Polish Złoty and the British Pound Sterling.

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 2023. The changes in the net carrying value of goodwill by segment are as follows (in millions):


	Composites		Insulation		Roofing		Total
Gross carrying amount at December 31, 2022	$	425	$	1,499	$	394	$	2,318




Foreign currency translation	1		7		1		9

5. GOODWILL AND OTHER INTANGIBLE ASSETS (continued)

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):


	June 30, 2023						December 31, 2022
	Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount
Indefinite-lived trademarks and trade names	$	991	$	—	$	991	$	989	$	—	$	989

(a)Other primarily includes emissions.

There are three indefinite-lived intangible assets that are at an increased risk of impairment. These intangible assets were partially impaired in the fourth quarter of 2022. If assumptions or estimates with respect to the Company’s future performance vary from what is expected, including those assumptions relating to interest rates, forecasted revenue, and economic and geopolitical uncertainty in Europe, future impairment analyses could result in a decline in fair value that may trigger a future impairment charge.

The following table presents the carrying values of these assets as of June 30, 2023:


Trade names and trademarks	June 30, 2023
European building and technical insulation trade name	$	89
Global cellular glass insulation trademark	$	80
Components branded roofing trademark	$	42

Amortization expense for intangible assets for the three and six months ended June 30, 2023 was $24 million and $42 million, respectively. Amortization expense for intangible assets for the three and six months ended June 30, 2022 was $12 million and $23 million, respectively. Amortization expense for intangible assets is estimated to be $55 million for the remainder of 2023.

Property, plant and equipment consist of the following (in millions):


	June 30, 2023		December 31, 2022
Land	$	168	$	166
Buildings and leasehold improvements	1,240		1,221

Machinery and equipment includes certain precious metals used in our production tooling, which comprise approximately 9% of total machinery and equipment as of both June 30, 2023 and December 31, 2022. 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. There were no non-cash exchanges during the three and six months ended June 30, 2023. 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. 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.

Receivables Securitization Facility

The Company has a Receivables Purchase Agreement (“RPA”) that is accounted for as secured borrowings in accordance with ASC 860, “Accounting for Transfers and Servicing.” Owens Corning Sales, LLC and Owens Corning Receivables LLC, each a subsidiary of the Company, have a $280 million RPA with certain financial institutions. The Company has the ability to borrow at the lenders’ cost of funds, which approximates A-1/P-1 commercial paper rates vs. SOFR, plus a spread. As of the June 30, 2023 discontinuation of LIBOR, fallback language in the RPA took effect to transition the facility to SOFR plus a spread. The RPA has been amended from time to time, with a maturity date in April 2024.

The RPA contains various covenants, including a maximum allowed leverage ratio that the Company believes are usual and customary for a securitization facility. The Company was in compliance with these covenants as of June 30, 2023. Please refer to the Credit Facility Utilization section below for liquidity information as of June 30, 2023.

Owens Corning Receivables LLC’s sole business consists of the purchase or acceptance through capital contributions of trade receivables and related rights from Owens Corning Sales, LLC and the subsequent retransfer of or granting of a security interest in such trade receivables and related rights to certain purchasers who are party to the RPA. Owens Corning Receivables LLC is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to be satisfied out of Owens Corning Receivables LLC’s assets prior to any assets or value in Owens Corning Receivables LLC becoming available to Owens Corning Receivables LLC’s equity holders. The assets of Owens Corning Receivables LLC are not available to pay creditors of the Company or any other affiliates of the Company or Owens Corning Sales, LLC.

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 presents the components of net periodic pension cost (in millions):


	Three Months Ended June 30,
	2023						2022
	U.S.		Non-U.S.		Total		U.S.		Non-U.S.		Total

Amortization of actuarial loss	3		1		4		6		1		7




Net periodic pension cost	$	—	$	4	$	4	$	2	$	—	$	2

The Company expects to contribute $25 million in cash to its defined benefit pension plans during 2023. Actual contributions to the plans may change as a result of a variety of factors, including changes in laws that impact funding requirements. The Company made cash contributions of $3 million to its defined benefit pension plans during the six months ended June 30, 2023.

Postemployment and Postretirement Benefits Other than Pensions (“OPEB”)

The Company maintains healthcare and life insurance benefit plans for certain retired employees and their dependents. The health care plans in the United States are non-funded and pay either (1) stated percentages of covered medically necessary expenses, after subtracting payments by Medicare or other providers and after stated deductibles have been met, or (2) fixed amounts of medical expense reimbursement.

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.

During the second quarter of 2023, the Company’s subsidiary, Paroc Group OY (“Paroc”), which the Company acquired in 2018, notified the appropriate European maritime regulatory authorities that specific insulation products in its marine insulation product line may not meet certain fire safety requirements in accordance with their certifications. Paroc has voluntarily withdrawn these specific products from the market, issued a recall for these products and suspended distribution and sales of these products. Paroc is cooperating with the applicable regulatory and government authorities and its customers to address the issue. The Company’s review of this matter is ongoing. We expect to incur costs associated with the resolution of this matter and it is possible that these costs may be material. The amount or range of any potential loss cannot be reasonably estimated at this time.

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 are required to use 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, 2023, the Company was involved with a total of 22 sites worldwide, including 10 Superfund and state or country equivalent sites and 12 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company.

13. CONTINGENT LIABILITIES AND OTHER MATTERS (continued)

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, 2023, the Company had an accrual totaling $5 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 20, 2023, the Company’s stockholders approved the Owens Corning 2023 Stock Plan (the “2023 Stock Plan”), which authorizes grants of stock options, stock appreciation rights, stock awards (including restricted stock awards, restricted stock units and bonus stock awards), performance share awards and performance share units. At June 30, 2023, the number of shares remaining available under the 2023 Stock Plan for all stock awards was approximately 3.4 million.

Prior to the 2023 Stock Plan, employees were eligible to receive stock awards under the Owens Corning 2019 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 June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Total stock-based compensation expense	$	14	$	13	$	27	$	25

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, 2023, there was no unrecognized compensation cost related to stock options and the exercise price on outstanding stock options was $37.65.

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


		Weighted-Average
	Number of Options	Exercise Price		Remaining Contractual Life (in years)	Intrinsic Value (in millions)
Outstanding, December 31, 2022	27,000	$	37.65	1.1	$	1

Exercised	(15,400)	37.65


Outstanding, June 30, 2023	11,600	$	37.65	0.6	$	1

14. STOCK COMPENSATION (continued)

Restricted Stock Units

The Company has granted restricted stock units (“RSUs”) under its stockholder approved stock plans. All outstanding RSUs will fully settle in stock. 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 plans allow alternate vesting schedules for death, disability, and retirement. The weighted-average grant date fair value of RSUs granted in 2023 was $99.02.

The following table summarizes the Company’s RSU activity:



	Number of RSUs	Weighted-Average Fair Value
Balance at December 31, 2022	1,276,160	$	69.16
Granted	333,291	99.02
Vested	(318,010)	69.93
Forfeited	(34,401)	84.18
Balance at June 30, 2023	1,257,040	$	76.25

As of June 30, 2023, there was $44 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, 2023 and 2022 was $22 million and $20 million, respectively.

Performance Share Units

The Company has granted performance share units (“PSUs”) as a part of its long-term incentive plan program under its stockholder approved stock plans. All outstanding performance share units will fully settle in stock. The amount of stock ultimately distributed from all performance share units is contingent on meeting internal Company-based metrics or an external-based stock performance metric.

In the six months ended June 30, 2023, the Company granted both internal Company-based and external-based metric PSUs.

Internal Company-based metrics

The internal Company-based metric PSUs are based on various Company metrics and typically vest over a three-year period. The amount of stock distributed will vary from 0% to 200% 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.

14. STOCK COMPENSATION (continued)

External-based metrics

The external-based metric PSUs vest after a three-year period. Outstanding grants issued in or after 2018 until 2022 were based on the Company’s total stockholder return relative to the performance of the Dow Jones U.S. Construction & Materials Index. Outstanding grants issued in 2023 are based on the Company’s total stockholder return relative to a peer group. 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.

The following table provides a summary of the assumptions for PSUs granted in 2023 and 2022:




	Six Months Ended June 30,
	2023		2022
Expected volatility	44.66%		41.65%
Risk free interest rate	3.75%		1.36%
Expected term (in years)	2.91		2.91
Grant date fair value of units granted	$	119.33	$	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, 2023, there was $23 million total unrecognized compensation cost related to PSUs. That cost is expected to be recognized over a weighted-average period of 1.89 years.

The following table summarizes the Company’s PSU activity:



	Number of PSUs	Weighted-Average Grant-Date Fair Value
Balance at December 31, 2022	303,716	$	91.47

Granted	155,469	101.76

Forfeited	(15,186)	95.59
Balance at June 30, 2023	443,999	$	94.59

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, 2023, 3.4 million shares remain available for purchase.

Included in total stock-based compensation expense is $2 million and $4 million of expense related to the Company’s ESPP recognized during the three and six months ended June 30, 2023, respectively. During the three and six months ended June 30, 2022, the Company recognized expense of $2 million and $3 million, respectively, related to the Company’s ESPP. As of June 30, 2023, there was $3 million of total unrecognized compensation cost related to the ESPP.

Basic	$	3.81	$	3.51	$	8.01	$	6.56
Diluted	$	3.78	$	3.49	$	7.94	$	6.52

For the three and six months ended June 30, 2023 and June 30, 2022, there were no non-vested RSUs or PSUs that had an anti-dilutive effect on earnings per share.

The Board of Directors approved two share repurchase programs in 2022 under which the Company is authorized to repurchase up to an aggregate of 20 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 2.6 million shares of its common stock for $250 million, inclusive of applicable taxes, during the six months ended June 30, 2023, under the Repurchase Authorization. As of June 30, 2023, 11.8 million shares remain available for repurchase under the Repurchase Authorization.

Effective tax rate	26		%	26		%	26		%	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, 2023 is primarily due to U.S. state and local income tax expense, foreign rate differential and U.S. federal taxes on foreign earnings. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the six months ended June 30, 2023 is primarily due to U.S. state and local income tax expense, foreign rate differential, and other discrete adjustments.

On August 16, 2022, the U.S. government enacted the Inflation Reduction Act of 2022 (the “Inflation Reduction Act”) into law, which includes a new corporate alternative minimum tax and an excise tax of 1% on the fair market value of net stock repurchases. Both provisions are effective for years after December 31, 2022. The Company does not anticipate being subject to the corporate alternative minimum tax in 2023 and continues to evaluate the potential future impact of the Inflation Reduction Act on its financial position and results of operations.

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.

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 committed to building a sustainable future through material innovation. 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 $345 million in the second quarter of 2023, compared to $343 million in the same period of 2022. The Company generated $534 million in adjusted earnings before interest and taxes (“Adjusted EBIT”) for the second quarter of 2023, compared to $525 million in the same period of 2022. See the Adjusted Earnings Before Interest and Taxes paragraph of the MD&A for further information regarding Adjusted EBIT, including the reconciliation to net earnings attributable to Owens Corning. Second quarter of 2023 earnings before interest and taxes (“EBIT”) performance compared to the same period of 2022 decreased $67 million in our Composites segment, and increased $6 million and $80 million in our Insulation and Roofing segments, respectively. Within our Corporate, Other and Eliminations category, General corporate expense and other increased by $10 million.

Cash and cash equivalents were $968 million as of June 30, 2023, compared to $810 million as of June 30, 2022. In the six months ended June 30, 2023, the Company’s operating activities provided $330 million of cash, compared to providing $624 million of cash in the same period in 2022.

In May 2023, the Company made the decision to exit the Protective Packaging business within the Roofing segment, including the production and sale of wood packaging, metal packaging and custom products. Exiting Protective Packaging will allow the Company to focus resources on the growth of its building materials products, which supports the future growth aspirations of the enterprise. With the exit of the Protective Packaging business, the Company will be closing its plants in Dorval, Quebec and Mission, British Columbia, Canada. The Company will also be significantly scaling back operations at its Novia facility in Qingdao, China. In connection with the exit of the Protective Packaging business, the Company estimates that it will incur cash charges of approximately $20 million, primarily related to severance and other exit costs. Additionally, the Company expects to incur total non-cash charges in the range of $65 to $75 million, primarily related to accelerated depreciation of property, plant and equipment and accelerated amortization of definite-lived intangibles. The Company expects to exit the majority of the business by the end of 2023 and expects to generate savings of approximately $7 million annually by 2024. During the second quarter of 2023, the Company recorded $29 million of charges, primarily related to severance costs, accelerated depreciation and accelerated amortization.

On March 3, 2023, the Company finalized the sale of the Company’s Insulation site in Santa Clara, California for total proceeds of $234 million, net of transaction fees. Total proceeds included a non-refundable deposit of $50 million received in the third quarter 2021. As a result, the Company recognized a pre-tax gain of $189 million in the first quarter of 2023, which is recorded in Gain on sale of site on the Consolidated Statements of Earnings.

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

The Board of Directors approved two share repurchase programs in 2022 under which the Company is authorized to repurchase up to an aggregate of 20 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 1.1 million shares of its common stock for $114 million, inclusive of applicable taxes, in the second quarter of 2023 under the Repurchase Authorization. As of June 30, 2023, 11.8 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 2023, net sales decreased $38 million and decreased $53 million, respectively, compared to the same periods in 2022. For the second quarter, the decrease in net sales was primarily driven by lower sales volumes partially offset by higher selling prices. For year-to-date, the decrease in net sales was driven by lower sales volumes and the unfavorable impact of translating sales denominated in foreign currencies into United States dollars, partially offset by higher selling prices and favorable customer and product mix.

GROSS MARGIN

In the second quarter and year-to-date 2023, gross margin increased $18 million and decreased $12 million, respectively, compared to the same periods in 2022. For the second quarter, the increase was primarily driven by higher selling prices across all three segments, offset by lower sales volumes and increased production downtime in both the Composites and Insulation segments. For year-to-date, the decrease was primarily driven by lower sales volumes, input cost inflation and the unfavorable net impact of acquisitions and divestitures, slightly offset by higher selling prices. Unfavorable manufacturing performance and higher production downtime also contributed to the decrease.

MARKETING AND ADMINISTRATIVE EXPENSES

In the second quarter and year-to-date 2023, marketing and administrative expenses increased $6 million and increased $26 million, respectively, compared to the same periods in 2022. The increase was driven primarily by ongoing inflationary pressures throughout the organization as well as higher general corporate expenses.

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

GAIN ON SALE OF SITE

In the first quarter of 2023, the Company finalized the sale of the Company’s Insulation site in Santa Clara, California resulting in the recognition of a pre-tax gain of $189 million.

OTHER EXPENSE (INCOME), NET

In the second quarter and year-to-date 2023, other expenses increased $8 million and increased $48 million, respectively, compared to the same periods in 2022. For the second quarter, the increase was driven primarily by lower gains on the sale of certain precious metals. For year-to-date, the increase was primarily driven by higher restructuring costs and lower gains on the sale of certain precious metals.

INTEREST EXPENSE, NET

In the second quarter and year-to-date 2023, interest expense, net, decreased $3 million and decreased $9 million, respectively, compared to the same periods in 2022 driven by higher interest income and capitalized interest.

INCOME TAX EXPENSE

Income tax expense for the three and six months ended June 30, 2023 was $121 million and $251 million, respectively. For the second quarter of 2023 and the six months ended June 30, 2023, 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, 2023 is primarily due to U.S. state and local income tax expense, foreign rate differential and U.S. federal taxes on foreign earnings. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the six months ended June 30, 2023 is primarily due to U.S. state and local income tax expense, 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, 2022 was $119 million and $226 million, respectively. For the second quarter of 2022 and 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.

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, productivity initiatives and 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.

The following table presents the impact and respective location of these income (expense) items on the Consolidated Statements of Earnings (in millions):

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.

Earnings before interest, taxes, depreciation and amortization (“EBITDA”) by segment is a non-GAAP measure that consists of EBIT plus depreciation and amortization. Segment EBITDA is used internally by the Company for analysis of performance.

NET SALES

In our Composites segment, net sales in the second quarter of 2023 decreased $99 million compared to the same period in 2022. The decrease was driven primarily by lower sales volumes of approximately 12%. Higher selling prices of $9 million were more than offset by the net impact of divestitures and acquisitions and unfavorable customer mix.

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

For year-to-date 2023, net sales in our Composites segment decreased $228 million compared to the same period in 2022. The decrease was driven primarily by lower sales volumes of approximately 15%. Higher selling prices of $39 million were offset by the net impact of divestitures and acquisitions and the unfavorable impact of translating sales denominated in foreign currencies into United States dollars. The remaining variance was driven by unfavorable customer mix.

EBIT

In our Composites segment, EBIT in the second quarter of 2023 decreased $67 million compared to the same period in 2022. The decrease was driven by lower sales volumes, the net unfavorable impact of divestitures and acquisitions of $19 million and higher production downtime of $14 million. Higher selling prices of $9 million and favorable delivery more than offset $11 million of input cost inflation. The remaining variance was driven by unfavorable customer mix partially offset by favorable manufacturing costs.

For the year-to-date 2023, EBIT in our Composites segment decreased $172 million compared to the same period in 2022. The decrease was driven by lower sales volumes and $34 million of higher production downtime. Higher selling prices of $39 million and favorable delivery offset input cost inflation of $41 million. The remaining variance was driven by the net unfavorable impact of divestitures and acquisitions of $33 million, unfavorable customer mix and higher manufacturing costs.

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 continued impacts of economic uncertainty, competitive pricing pressure and input cost inflation. The Company remains focused on managing costs, capital expenditures, and working capital.

Insulation

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


	Three Months Ended June 30,						Six Months Ended June 30,

EBITDA	$	220		$	208		$	427		$	390
EBITDA as a % of net sales	24		%	22		%	23		%	22		%

NET SALES

In our Insulation segment, net sales in the second quarter of 2023 decreased $29 million compared to the same period in 2022. The decrease was driven primarily by lower sales volumes of approximately 15% partially offset by higher selling prices of $73 million, favorable product and customer mix and $9 million from the favorable net impact of acquisitions and divestitures.

For year-to-date 2023, net sales in our Insulation segment increased $31 million compared to the same period in 2022. The increase was driven by higher selling prices of $185 million and favorable customer and product mix, partially offset by lower sales volumes of approximately 12%. The favorable net impact of acquisitions and divestitures more than offset $16 million of the 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 Insulation segment, EBIT in the second quarter of 2023 increased $6 million compared to the same period in 2022. Higher selling prices of $73 million and favorable customer and product mix more than offset lower sales volumes, $14 million of input cost inflation and $10 million of higher manufacturing costs. Favorable delivery of $8 million was offset by higher production downtime.

For the year-to-date 2023, EBIT in our Insulation segment increased $33 million compared to the same period in 2022. Higher selling prices of $185 million more than offset lower sales volumes and $56 million of input cost inflation. Higher manufacturing costs of $23 million and higher production downtime was partially offset by favorable customer and product mix, as well as, favorable delivery of $8 million.

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 2023, the average Seasonally Adjusted Annual Rate (“SAAR”) of U.S. housing starts was approximately 1.447 million, down from an annual average of approximately 1.652 million starts in the second quarter of 2022.

The Company expects both the North American new residential construction market and global commercial and industrial construction markets to remain soft temporarily with the weaker macro-economic outlook, higher interest rates and continued input cost inflation. The Company remains focused on managing costs, capital expenditures, and working capital.

Roofing

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


	Three Months Ended June 30,						Six Months Ended June 30,

EBITDA	$	354		$	275		$	579		$	465
EBITDA as a % of net sales	32		%	27		%	29		%	25		%

NET SALES

In our Roofing segment, net sales in the second quarter of 2023 increased $105 million compared to the same period in 2022 due to higher sales volumes of 6% and higher selling prices of $40 million. Favorable customer and product mix were offset by lower third-party asphalt sales.

For year to date 2023, net sales in our Roofing segment increased $162 million compared to the same period in 2022. Higher selling prices of $126 million, higher sales volumes of 2% and favorable customer and product mix were partially offset by lower third-party asphalt sales of $15 million.

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

EBIT

In our Roofing segment, EBIT in the second quarter of 2023 increased $80 million compared to the same period in 2022 due to higher selling prices of $40 million and higher sales volumes. Lower input costs, including delivery, and favorable customer and product mix more than offset higher manufacturing costs of $12 million and higher selling, general and administrative expenses.

For year-to-date 2023, EBIT in our Roofing segment increased $113 million compared to the same period in 2022 driven primarily by higher selling prices of $126 million. Lower delivery costs of $16 million, higher sales volumes and favorable customer and product mix offset higher production costs and $8 million of input cost inflation. The remaining variance was driven by higher selling, general and administrative expenses.

OUTLOOK

In our Roofing segment, the Company expects the North American new residential construction market to remain soft temporarily. Other uncertainties that may impact Roofing demand include demand from storms and other weather-related events, demand from repair and remodeling activity, competitive pricing pressure and the cost and availability of raw materials, particularly asphalt. 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 2023 were higher by $21 million compared to the same period in 2022, primarily driven by the quarter over quarter increase of restructuring charges and general corporate expenses. For year-to-date 2023, EBIT expenses in Corporate, Other and Eliminations were lower by $116 million. EBIT improvement was primarily driven by the pre-tax gain on the Santa Clara, California site partially offset by the year over year increase of restructuring charges and general corporate expenses.

General corporate expense and other for the second quarter of 2023 were higher by $10 million compared to the same period in 2022. For year-to-date, general corporate expense and other were higher by $21 million compared to the same period in 2022.

OUTLOOK

In 2023, we estimate general corporate expenses to be in the range of $215 million and $225 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 $968 million as of June 30, 2023, 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, 2023
	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, 2023, the Company had $3.0 billion of total debt and cash and cash equivalents of $968 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, 2023.

In May 2023, the Senior Revolving Credit Facility was amended to formally adopt SOFR plus a spread as the benchmark reference rate in anticipation of the June 30, 2023 discontinuation of LIBOR.

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, 2023, and December 31, 2022, the Company had $81 million and $188 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.

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 annual report on Form 10-K for the year ended December 31, 2022 (the “2022 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 2022 Form 10-K for more details on these material cash requirements. During the second quarter of 2023, there have been no material changes to our expected uses of cash and contractual obligations.

Supplier Finance Programs

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.

Please refer to the Supplier Finance Programs section in Note 1 of the Consolidated Financial Statements for a description of outstanding obligations and payments under the supplier finance programs.

Cash Flows

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


	Six Months Ended June 30,
		2023		2022
Cash and cash equivalents		$	968	$	810
Net cash flow provided by operating activities		330		624
Net cash flow used for investing activities		(102)		(340)
Net cash flow used for financing activities		(385)		(429)
Availability on the Senior Revolving Credit Facility		796		796
Availability on the Receivables Securitization Facility		279		279

Operating activities: For the six months ended June 30, 2023, the Company’s operating activities provided $330 million of cash compared to $624 million provided in the same period of 2022. The decrease in cash provided by operating activities was primarily due to decreases in accounts payable, partially offset by increases to inventory and higher earnings when compared to the same period in 2022.

Investing activities: Net cash flow used for investing activities decreased by $238 millions for the six months ended June 30, 2023, compared to the same period in 2022. The decrease was due to the proceeds received from the sale of the Santa Clara site in March 2023 and lower investments in subsidiaries for the period, partially offset by higher capital spending.

Financing activities: Net cash flow used for financing activities decreased by $44 million for the six months ended June 30, 2023 compared to the same period of 2022, resulting from lower treasury stock purchases for the period which more than offset increased dividend payments.

SAFETY

One of our primary objectives is the safety and well-being of our employees. Working safely is an unconditional, organization-wide expectation at Owens Corning, which we believe directly benefits employees’ lives, improves our manufacturing processes and reduces our costs. The Company maintains comprehensive safety programs focused on identifying hazards and eliminating risks that can lead to severe injuries.
