Accounting Changes and Error Corrections [Abstract]
GENERAL	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 $17 million was recognized as revenue in the first nine months of 2023. As of September 30, 2023, our contract liability balances totaled $96 million. As of December 31, 2021, our contract liability balances totaled $76 million, of which $16 million was recognized as revenue in the first nine months of 2022. As of September 30, 2022, our contract liability balances totaled $86 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 September 30, 2023, $8 million as of December 31, 2022, and $7 million as of September 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 $22 million and $72 million for the three and nine months ended September 30, 2023, respectively, and $42 million and $102 million for the three and nine months ended September 30, 2022, respectively. As of September 30, 2023 and December 31, 2022, amounts due to the related party supplier were $5 million and $3 million, respectively. 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 $205 million and $234 million as of September 30, 2023 and December 31, 2022, respectively. The amounts of invoices paid under the Programs totaled $454 million and $481 million for the nine months ended September 30, 2023 and September 30, 2022, respectively.

DERIVATIVE FINANCIAL INSTRUMENTS	9 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS	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 September 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 their respective location on the Consolidated Balance Sheets (in millions): Fair Value at Location September 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: Cash flow hedges: Natural gas forward swaps Other current liabilities $ 15 $ 32 Derivative assets not designated as hedging instruments: Foreign exchange forward contracts Other current assets $ 1 $ 1 Derivative liabilities not designated as hedging instruments: Foreign exchange forward contracts Other current liabilities $ 1 $ 2 Consolidated Statements of Earnings Activity The following table presents the impact and respective location of derivative activities on the Consolidated Statements of Earnings (in millions): Three Months Ended Nine Months Ended Location 2023 2022 2023 2022 Derivative activity designated as hedging instruments: Natural gas cash flow hedges: Amount of loss (gain) reclassified from AOCI (as defined below) into earnings (a) Cost of sales $ 10 $ (21) $ 42 $ (47) Cross-currency swap net investment hedges: Amount of gain recognized in earnings on derivative amounts excluded from effectiveness testing Interest expense, net $ — $ — $ — $ (1) Derivative activity not designated as hedging instruments: Foreign currency: Amount of (gain) loss recognized in earnings (b) Other expense (income), net $ — $ (26) $ 4 $ (54) Treasury interest rate lock: Amount of gain recognized in earnings Other expense (income), net $ — $ (6) $ — $ (6) (a) Accumulated Other Comprehensive Earnings (Deficit) (“AOCI”) (b) Gains related to foreign currency derivatives were substantially offset by net revaluation impacts on foreign currency denominated balance sheet exposures, which were also recorded in Other expense (income), net.

Consolidated Statements of Comprehensive Earnings Activity The following table presents the impact of derivative activities on the Consolidated Statements of Comprehensive Earnings (in millions): Amount of Gain Recognized in Comprehensive Earnings Three Months Ended Nine Months Ended Hedging Type Derivative Financial Instrument 2023 2022 2023 2022 Net investment hedge Cross-currency swaps $ — $ — $ — $ (5) Cash flow hedge Natural gas forward swaps $ (6) $ (4) $ (14) $ (17) Cash flow hedge Treasury interest rate lock $ — $ (2) $ — $ (21) 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 September 30, 2023, the notional amounts of these natural gas forward swaps was 7 million MMBtu (or MMBtu equivalent) based on U.S. and European indices. The Company has designated these natural gas forward swaps as cash flow hedges, with the last hedge maturing no later than December 2024. A net unrecognized loss of $15 million related to these natural gas forward swaps was included in AOCI as of September 30, 2023, $15 million of which is expected to be reclassified into earnings within the next twelve months. 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 September 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. 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 September 30, 2023, the Company had notional amounts of $159 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 the European Euro. In addition, the Company had notional amounts of $30 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.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND OTHER INTANGIBLE ASSETS	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 nine 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 Acquisitions and Divestitures (1) — — (1) Foreign currency translation — (10) (1) (11) Gross carrying amount at September 30, 2023 424 1,489 393 2,306 Accumulated impairment losses at December 31, 2022 — (935) — (935) Foreign currency translation — 7 — 7 Accumulated impairment losses at September 30, 2023 — (928) — (928) Balance, net of impairment, at September 30, 2023 $ 424 $ 561 $ 393 $ 1,378 Other Intangible Assets Other intangible assets consist of the following (in millions): September 30, 2023 December 31, 2022 Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Accumulated Net Indefinite-lived trademarks and trade names $ 988 $ — $ 988 $ 989 $ — $ 989 Amortizable intangible assets Customer relationships 635 (295) 340 638 (243) 395 Technology 328 (202) 126 330 (187) 143 Trademarks 12 (1) 11 12 — 12 Other (a) 63 (2) 61 66 (3) 63 Total other intangible assets $ 2,026 $ (500) $ 1,526 $ 2,035 $ (433) $ 1,602 (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 September 30, 2023: Trade names and trademarks September 30, 2023 European building and technical insulation trade name $ 86 Global cellular glass insulation trademark $ 80 Components branded roofing trademark $ 42 Amortization expense for intangible assets for the three and nine months ended September 30, 2023 was $28 million and $70 million, respectively. Amortization expense for intangible assets for the three and nine months ended September 30, 2022 was $14 million and $37 million, respectively. Amortization expense for intangible assets is estimated to be $27 million for the remainder of 2023. The estimated amortization expense for intangible assets for the next five fiscal years ended December 31 is as follows (in millions): Period Amortization 2024 $ 64 2025 $ 57 2026 $ 42 2027 $ 34 2028 $ 33

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 nine months ended September 30, 2023. During the three and nine months ended September 30, 2022, these non-cash exchanges resulted in a net increase to Machinery and equipment of $7 million and $18 million, respectively, and gains totaling $7 million and $18 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.

Restructuring and Related Activities [Abstract]
RESTRUCTURING, ACQUISITION AND DIVESTITURE-RELATED COSTS	RESTRUCTURING, ACQUISITION AND DIVESTITURE-RELATED COSTS The Company may incur restructuring, transaction and integration costs related to acquisitions and divestitures, and may incur restructuring and other exit costs in connection with its global cost reduction, product line and productivity initiatives and the Company’s growth strategy. Protective Packaging Exit 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. During the first nine months of 2023, the Company recorded $61 million of charges, of which $49 million were non-cash charges, primarily related to accelerated depreciation and amortization and $12 million of cash charges, primarily related to severance. Wabash Facility Closure In April 2023, the Company took actions to support its strategy to operate a flexible and cost-efficient manufacturing network through decisions to relocate the Wabash, Indiana mineral wool operations to Joplin, Missouri, and to exit the granulated mineral wool market. These actions are expected to result in cumulative incremental costs of approximately $30 million, primarily related to severance and accelerated depreciation. During the first nine months of 2023, the Company recorded $23 million of charges, primarily related to accelerated depreciation and severance. European Operating Structure Optimization In March 2023, the Company took actions to optimize the operating structure of its segments across Europe to increase its competitiveness. These actions are expected to result in cumulative incremental costs of approximately $20 million, primarily related to severance and other exit costs. During the first nine months of 2023, the Company recorded $12 million of charges primarily related to severance costs. Composites Strategic Realignment Actions On July 1, 2022, the Company finalized 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 $30 million in Other expense (income), net on the Consolidated Statements of Earnings in 2022 to reflect the fair value less cost to sell the assets. The Company also took actions 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.

Defined Benefit Plans and Other Postretirement Benefit Plans Disclosures [Abstract]
PENSION PLANS AND OTHER POSTRETIREMENT BENEFITS	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 September 30, 2023 2022 U.S. Non-U.S. Total U.S. Non-U.S. Total Components of Net Periodic Pension Cost Service cost $ 1 $ — $ 1 $ 3 $ 1 $ 4 Interest cost 8 4 12 6 3 9 Expected return on plan assets (10) (4) (14) (9) (4) (13) Amortization of actuarial loss 1 1 2 2 — 2 Net periodic pension cost $ — $ 1 $ 1 $ 2 $ — $ 2 Nine Months Ended September 30, 2023 2022 U.S. Non-U.S. Total U.S. Non-U.S. Total Components of Net Periodic Pension Cost Service cost $ 2 $ 2 $ 4 $ 5 $ 3 $ 8 Interest cost 24 12 36 18 8 26 Expected return on plan assets (30) (11) (41) (27) (12) (39) Amortization of actuarial loss 4 2 6 8 1 9 Net periodic pension cost $ — $ 5 $ 5 $ 4 $ — $ 4 The Company expects to contribute $20 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 $4 million to its defined benefit pension plans during the nine months ended September 30, 2023. On October 12, 2023, the Company entered into an agreement to purchase a non-participating annuity contract from an insurance company to transfer $291 million of the Company's outstanding pension projected benefit obligation related to certain U.S. and non U.S. pension plans. The transaction is expected to close in the fourth quarter of 2023 and will be funded with pension plan assets of $268 million. As a result of this transaction, the Company will recognize a pre-tax settlement charge in the range of approximately $135 million to $150 million in the fourth quarter of 2023 from the accelerated recognition of a pro rata portion of plan actuarial losses. This charge will be recorded in Non-operating (income) expense on the Consolidated Statements of Earnings. The transaction is not expected to have a material impact on the plans' funded statuses. 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.

CONTINGENT LIABILITIES AND OTHE

CONTINGENT LIABILITIES AND OTHER MATTERS	9 Months Ended
	Sep. 30, 2023
Commitments and Contingencies Disclosure [Abstract]
CONTINGENT LIABILITIES AND OTHER MATTERS	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, except as noted below. 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 recalls, and suspended distribution and sales of these products. Paroc is cooperating with the applicable regulatory and government authorities and continues to work with its customers and end-users to assist with remediation. We established an estimated liability for expected future costs related to this matter on our Consolidated Balance Sheet as of September 30, 2023. The estimated liability is primarily based on assumptions related to the estimated costs of the remedy for the recall. We will reevaluate these assumptions each period, and the related liability may be adjusted when factors indicate that the liability is either not sufficient to cover or exceeds the estimated product recall costs. Based on the factors currently known, we believe the appropriate liability has been established at this time. It is reasonably possible that additional product recall costs could be incurred that exceed the estimated liability by amounts that could be material to our consolidated financial statements. 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 September 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.

Share-Based Payment Arrangement [Abstract]
STOCK COMPENSATION	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 September 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 Nine Months Ended 2023 2022 2023 2022 Total stock-based compensation expense $ 11 $ 13 $ 38 $ 38 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 September 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 Intrinsic Value (in millions) Outstanding, December 31, 2022 27,000 $ 37.65 1.1 $ 1 Exercised (17,900) 37.65 Outstanding, September 30, 2023 9,100 $ 37.65 0.4 $ 1 Exercisable, September 30, 2023 9,100 $ 37.65 0.4 $ 1 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 The following table summarizes the Company’s RSU activity: Number of RSUs Weighted-Average Balance at December 31, 2022 1,276,160 $ 69.16 Granted 353,809 101.19 Vested (355,975) 68.82 Forfeited (64,489) 86.96 Balance at September 30, 2023 1,209,505 $ 77.37 As of September 30, 2023, there was $41 million of total unrecognized compensation cost related to RSUs. That cost is expected to be recognized over a weighted-average period of 2.43 years. The total grant date fair value of shares vested during the nine months ended September 30, 2023 and 2022 was $24 million and $21 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 nine months ended September 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. 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: Nine Months Ended September 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 September 30, 2023, there was $21 million total unrecognized compensation cost related to PSUs. That cost is expected to be recognized over a weighted-average period of 1.75 years. The following table summarizes the Company’s PSU activity: Number Weighted-Average Balance at December 31, 2022 303,716 $ 91.47 Granted 164,128 101.76 Vested (24,120) 76.58 Forfeited (52,491) 94.94 Balance at September 30, 2023 391,233 $ 95.80 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 September 30, 2023, 3.4 million shares remain available for purchase.

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 3.6 million shares of its common stock for $391 million, inclusive of applicable taxes, during the nine months ended September 30, 2023, under the Repurchase Authorization. As of September 30, 2023, 10.8 million shares remain available for repurchase under the Repurchase Authorization.

INCOME TAXES	INCOME TAXES The following table provides the Income tax expense (in millions) and effective tax rate for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 Income tax expense $ 110 $ 114 $ 361 $ 340 Effective tax rate 25 % 20 % 25 % 23 % The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended September 30, 2023 is primarily due to U.S. state and local income tax expense, offset slightly by U.S. federal taxes on foreign earnings and U.S. federal income tax credits. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the nine months ended September 30, 2023 is primarily due to U.S. state and local income tax expense and foreign rate differential. 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 September 30, 2022 is primarily due to U.S. state and local income tax expense, non-taxable gain on acquisition, 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 nine months ended September 30, 2022 is primarily due to U.S. state and local income tax expense, non-taxable gain on acquisition, U.S. federal taxes on foreign earnings, adjustments to valuation allowances against certain deferred tax assets, excess tax benefits related to stock compensation, and other discrete adjustments. The Company continues to assert indefinite reinvestment in accordance with ASC 740 based on the laws as of enactment of the tax legislation.
