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 (“SEC”), 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, 2023 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, 2023 (the “2023 Form 10-K”). Certain reclassifications have been made to the periods presented for 2023 to conform to the classifications used in the periods presented for 2024.

Acquisition of Masonite International Corporation

On May 15, 2024, the Company acquired all of the outstanding shares of Masonite International Corporation (“Masonite”) at a purchase price of $133.00 per share (the "Arrangement"). Masonite is a leading global designer, manufacturer, marketer and distributor of interior and exterior doors and door systems for residential new construction and residential repair and remodeling. The addition of Masonite's market-leading doors business creates a new growth platform for the Company, strengthening the Company's position in building and construction and expanding its offering of branded residential building products.

Masonite's operating results and preliminary purchase price allocation have been included in the Company's newly established Doors reportable segment from May 15, 2024, the effective date of the Arrangement, within the Consolidated Financial Statements. Please refer to Note 7 of the Consolidated Financial Statements for further information.

Revenue Recognition

As of December 31, 2023, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $101 million, of which $17 million was recognized as revenue in the first six months of 2024. As of June 30, 2024, our contract liability balances totaled $112 million.

As of December 31, 2022, our contract liability balances 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.

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 $20 million as of June 30, 2024, $9 million as of June 30, 2023 and $8 million as of December 31, 2023 and December 31, 2022. Restricted cash primarily represents cash we have placed as collateral for standby letters of credit and amounts received from a counterparty related to its performance assurance on an executory contract. The letters of credit guarantee payment to third parties in the event the Company is in breach of contract terms as detailed in each letter of credit. The amounts received from a counterparty are contractually required to be set aside, and the counterparty can exchange the cash for another form of performance assurance at its discretion. These amounts are included in Other current assets on the Consolidated Balance Sheets.

Accounts Receivable

Our customers consist mainly of distributors, home centers, contractors and retailers. Two of our largest customers accounted for 21% and 16%, respectively, of consolidated accounts receivable as of June 30, 2024 and 11% and 11%, respectively, of consolidated accounts receivable as of December 31, 2023.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (continued)

(unaudited)

1. GENERAL (continued)

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 $33 million and $65 million for the three and six months ended June 30, 2024, respectively and $29 million and $50 million for the three and six months ended June 30, 2023, respectively. As of June 30, 2024 and December 31, 2023, amounts due to the related party supplier were $7 million and $5 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 $188 million and $211 million as of June 30, 2024 and December 31, 2023, respectively. The amounts of invoices paid under the Programs totaled $257 million and $307 million for the six months ended June 30, 2024 and June 30, 2023, respectively.

Strategic Actions

On February 9, 2024, the Company announced the decision to review strategic alternatives for its global glass reinforcements (“GR”) business, consistent with our strategy to focus on building and construction materials. The GR business, which operates within our Composites segment, supplies a wide variety of glass fiber products for applications in wind energy, infrastructure, industrial, transportation, and consumer markets. The GR business generates annual revenues of approximately $1.3 billion. While a range of options are under consideration, including a potential sale, spin-off or other strategic option, there can be no assurance that the strategic review will result in any transaction or other outcome. During the first six months of 2024, the Company incurred $17 million of costs related to this review.

Accounting Policies

There have been no changes in the significant accounting policies from those that were disclosed in the 2023 Form 10-K.

Critical Accounting Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from such estimates. Accounting estimates and assumptions discussed in this section are those considered to be the most critical to an understanding of our financial statements because they involve significant judgments and uncertainties. There have been no material changes to our critical accounting

estimates previously disclosed in Item 7 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, except as follows:

Fair values of assets acquired and liabilities assumed in acquisitions — Assets acquired and liabilities assumed in a business combination are recorded at their estimated fair values on the date of acquisition. The difference between the purchase price amount and the net fair value of assets acquired and liabilities assumed is recognized as goodwill on the balance sheet if the purchase price exceeds the estimated net fair value or as a bargain purchase gain on the income statement if the purchase price is less than the estimated net fair value. We apply significant judgment in estimating the fair value of assets acquired and liabilities assumed, which involves the use of significant estimates and assumptions. Changes in these judgments or estimates can have a material impact on the valuation of the respective assets and liabilities acquired and our results of operations in periods after acquisition. The allocation of the purchase price is preliminary for up to one year after the acquisition date as more information is obtained about the fair value of assets acquired and liabilities assumed. See Note 7 of the Consolidated Financial Statements for further information on the fair values of assets acquired and liabilities assumed in recent business combinations.

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, 2024 and December 31, 2023, 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	June 30, 2024		December 31, 2023

Cash Flow Hedges

The Company uses a combination of derivative financial instruments, which qualify as cash flow hedges, and physical contracts to manage forecasted exposure to electricity and natural gas prices. As of June 30, 2024, the notional amounts of these natural gas forward swaps were 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 September 2025. A net unrecognized loss of $2 million related to these natural gas forward swaps was included in AOCI as of June 30, 2024, $2 million of which is expected to be reclassified into earnings within the next twelve months.

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.

In May 2024, the Company issued new senior notes and began amortizing the $31 million over the life of the Company's 5.700% senior notes due 2034. The unrecognized gain of $31 million was included in AOCI as of June 30, 2024.

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, 2024, the Company had notional amounts of $117 million for non-designated derivative financial instruments related to foreign currency exposures in United States Dollars primarily related to the Brazilian Real, Indian Rupee, Chinese Yuan, Korean Won, Hong Kong Dollar, and the Chilean Peso. In addition, the Company had notional amounts of $58 million for non-designated derivative financial instruments related to foreign currency exposures in European Euro primarily related to the Polish Złoty, Danish Krone, Norwegian Krone 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 2024. The changes in the net carrying value of goodwill by segment are as follows (in millions):


	Roofing		Insulation		Doors		Composites		Total
Gross carrying amount at December 31, 2023	$	395	$	1,520	$	—	$	425	$	2,340

5. GOODWILL AND OTHER INTANGIBLE ASSETS (continued)

The annual impairment tests performed in the fourth quarter of 2023 indicated that the business enterprise value of the Composites reporting unit exceeded its carrying value by approximately 5%. There is uncertainty surrounding the macroeconomic factors that impact this reporting unit and a sustained downturn in these factors or a change in the long-term revenue growth or profitability for this reporting unit could increase the likelihood of a future impairment.

Other Intangible Assets

The Company amortizes the cost of other intangible assets over their estimated useful lives which, individually, range up to 25 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, 2024						December 31, 2023
	Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount		Gross Carrying Amount		Accumulated Amortization		Net Carrying Amount

(a) Other primarily includes emissions rights.

There are two indefinite-lived intangible assets that are at an increased risk of impairment, both of which are used by our Insulation segment and were partially impaired in the fourth quarter of 2022. A change in the estimated long-term revenue growth rate or discount rate for the segment could increase the likelihood of a future impairment.

The following table presents the carrying values of these assets as of June 30, 2024:


Trademarks and trade names	June 30, 2024
European building and technical insulation trade name	$	87
Global cellular glass insulation trademark	$	80

Amortization expense for intangible assets for the three and six months ended June 30, 2024 was $39 million and $55 million, respectively. 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 is estimated to be $85 million for the remainder of 2024.

7. ACQUISITIONS

On February 8, 2024, the Company entered into an Arrangement Agreement (the "Arrangement Agreement") with Masonite International Corporation, a British Columbia corporation ("Masonite"), pursuant to which the Company agreed to acquire all of the issued and outstanding common shares of Masonite at a purchase price of $133.00 per share (the "Arrangement"). On May 15, 2024, as determined by the Arrangement Agreement, the Company completed the acquisition of 100% of the issued and outstanding shares of Masonite for $133.00 per share in cash, without interest for a total purchase price of $3.2 billion. The acquisition was funded primarily with debt proceeds of $2.8 billion and cash on hand. Please refer to the discussion under "364-Day Credit Facility" in Note 11 of the Consolidated Financial Statements for further information.

Masonite is a leading global designer, manufacturer, marketer and distributor of interior and exterior doors and door systems for the residential new construction and residential repair and remodeling markets. The addition of Masonite's market-leading doors business creates a new growth platform for the Company, strengthening the Company's position in building and construction and expanding its offering of branded residential building products.

Masonite's operating results and preliminary purchase price allocation have been included in the Company's newly established Doors reportable segment from May 15, 2024, the effective date of the Arrangement, within the Consolidated Financial Statements. Masonite contributed revenues of $311 million and earnings of $25 million to the Company for the period from May 15, 2024 to June 30, 2024. Please refer to Note 2 of the Consolidated Financial Statements for further information.

During the second quarter and first six months of 2024, the Company incurred $29 million and $47 million, respectively, of transaction costs related to the Arrangement. These expenses are included in Other expense, net on the Company's consolidated statement of earnings for the three and six months ended June 30, 2024.

The fair value of the total purchase consideration transferred was determined as follows (in millions):


	Fair Value of Purchase Consideration
Closing cash consideration	$	2,935
Pre-combination vesting portion of fair value of Masonite outstanding equity awards converted to Owens Corning time vesting RSUs	35
Repayment of Masonite term loan facility	216
Total transaction consideration	$	3,186

The closing cash as part of preliminary estimated consideration was calculated at the price of $133.00 per outstanding Masonite common share. At the close of the acquisition of Masonite, there were 22.07 million Masonite common shares outstanding.

The preliminary estimated fair value of Owens Corning common stock underlying Masonite outstanding equity awards that have been converted into awards with respect to Owens Corning common stock is calculated as follows (in millions, except share and per share amounts:


	Amount
Number of Masonite stock awards outstanding (a)	639,608
Exchange ratio (b)	0.7642
Owens Corning equity awards issued for Masonite outstanding equity awards	488,778
10-day weighted average closing share price of Owens Corning common stock (c)	$	174.03
Fair value of Owens Corning time vesting RSUs issued for Masonite outstanding equity awards	$	85
Less: Estimated fair value allocated to post-transaction compensation expense	(50)
Fair value of awards included in transaction consideration	$	35

(a) Represents the Masonite stock awards that have been converted into Owens Corning equity awards upon completion of the acquisition of Masonite, based on awards outstanding at May 15, 2024. Masonite equity awards include awards issued under various stock incentive plans of Masonite.

(b) The exchange rate was determined by the consideration amount divided by the volume weighted average closing sale price of one share of Owens Corning common stock for the ten consecutive trading days ended May 15, 2024, in accordance with the terms of the Arrangement Agreement.

(c) The ten-day weighted average closing share price was calculated for the ten consecutive trading days ended May 15, 2024, in accordance with the terms of the Arrangement Agreement.

On May 15, 2024, the effective date of the Arrangement, the Company transferred consideration to Masonite to repay the Masonite 2027 term loan facility (the "Masonite term loan facility"). This repayment was required by the change in control provision within the terms of the Masonite term loan facility.

The Company has applied the acquisition method of accounting in accordance with Accounting Standards Codification ("ASC") Topic 805, Business Combinations, and recognized assets acquired and liabilities assumed at their fair values as of the effective date of the Arrangement, with the excess purchase consideration recorded to goodwill. The Company has not yet finalized the valuation of the assets acquired and liabilities assumed as of June 30, 2024. The Company is continuing to obtain information to complete its valuation of certain assets and liabilities. Preliminary estimates have been recorded and additional adjustments may be recorded to the fair value of intangible assets, property, plant and equipment, goodwill and deferred income taxes among other items during the measurement period, a period not to exceed 12 months from the acquisition date.

7. ACQUISITIONS (continued)

Goodwill

Preliminary purchase consideration allocation resulted in $1.3 billion in goodwill. The goodwill is not deductible for tax purposes. The factors contributing to the recognition of the amount of goodwill are based on several strategic and synergistic benefits that are expected to be realized from the acquisition.

Receivables

The fair value of receivables acquired is $330 million, with the gross contractual amount being $331 million. The Company expects $1 million to be uncollectible.

Inventory

The fair value of inventory was determined by the market selling price of the inventory, less the remaining manufacturing and selling costs and a normal profit margin on those manufacturing and selling efforts. The fair value of inventory has been stepped up by $18 million, this amount will be amortized to Cost of Sales as the inventory is sold. We expect to fully amortize this amount by the third quarter of 2024.

Property, Plant and Equipment

The preliminary fair value of property, plant and equipment is $861 million and was determined using cost and market approaches. The cost approach reflects the amount that would be required to replace the asset to service capacity, this approach was used where there was historical data available. Where there was not historical data available the market approach was used, this approach reflects recent sales of identical or comparable assets.

Intangible Assets

The preliminary fair value of acquired intangible assets is $1.6 billion. The fair value of customer relationships was determined using the multi-period excess earnings method. Key assumptions under this method are future cash flow estimates, customer attrition, discount rate, contributory asset charges and tax amortization benefits. The fair value of trade names were determined using the relief from royalty method. Key assumptions under this method are future cash flow estimates, royalty rate, discount rate and tax amortization benefits.


	Estimated Useful Life (in years)	Preliminary Estimated Asset Fair Value (in millions)
Customer relationships	10 - 21	$	1,192
Technology	5	128
Trademarks and trade names (indefinite-lived)	Indefinite	240
Trademarks and trade names	10	19
Identifiable intangible assets, net		$	1,579

Debt

The fair value of Masonite's unsecured senior notes was determined using the market approach, based on the trading value of the notes in the market.

Joint Ventures and Non-Controlling Interests

The Company's acquisition of Masonite included joint ventures with Dominance Industries, Inc., 45% owned, and Vanair Design Inc., 30% owned as well as a 25% non-controlling interest in Sacopan Inc. owned by a third party and a 50% non-controlling interest in Magna Foremost SDN BHD owned by a third party. The value of these investments and non-controlling interests were determined using an equally weighted value from the income approach and the market approach.

On May 15, 2024, the Company initially borrowed $295 million on the Receivables Securitization Facility, which was used to pay down a portion of the 364-Day Credit Facility. Subsequent to the May 15, 2024 borrowing, the Company repaid and re-borrowed on the Receivables Securitization Facility throughout the quarter to pay down portions of the 364-Day Credit Facility. As of June 30, 2024, there was a remaining balance on the Receivables Securitization Facility of $155 million. Please refer to the Credit Facility Utilization section below for liquidity information as of June 30, 2024.

364-Day Credit Facility

On March 1, 2024, the Company entered into an unsecured term loan agreement in an aggregate principal amount of $3.0 billion, which matures 364 days after the facility is initially funded with a single drawing (the “364-Day Credit Facility”).

In May 2024, to fund a portion of the purchase of Masonite, the Company borrowed $2.8 billion using Term SOFR plus a spread on the 364-Day Credit Facility. As a result of the borrowing, the Company incurred approximately $16 million of financing fees which were amortized to Interest expense, net on the Consolidated Statements of Earnings. During the quarter, the Company completely repaid the 364-Day Credit Facility with a combination of issuance of new senior notes, borrowings on the Receivables Securitization Facility and cash on hand. Based on terms of the agreement, no further amounts can be drawn.

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,
	2024						2023
	U.S.		Non-U.S.		Total		U.S.		Non-U.S.		Total

Amortization of actuarial loss	1		2		3		3		1		4




Net periodic pension cost	$	(1)	$	4	$	3	$	—	$	4	$	4

The Company expects to contribute $20 million in cash to its defined benefit pension plans during 2024. 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, 2024.

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. Except as set forth below under “Litigation and Regulatory Proceedings,” 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. 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 products in its marine insulation product line may not meet certain fire safety requirements in accordance with their certifications. Paroc voluntarily withdrew these specific products from the market, issued recalls, and suspended distribution and sales of these products (the “Recalled Products”). Paroc continues to cooperate with the applicable regulatory and government authorities and work with its customers and end-users to assist with remediation for the recall. During the first quarter of 2024, the Company discovered potential nonconformances relating to two other marine insulation product lines. In April 2024, Paroc suspended sales of these marine insulation products as a precautionary measure while it reviews the potential nonconformances, but has not issued recalls. The Company has included an estimated liability for expected future costs related to the Recalled Products on its Consolidated Balance Sheets as of June 30, 2024 and December 31, 2023. The estimated liability is primarily based on assumptions related to the estimated costs of the remedy for the Recalled Products. At this time, we cannot estimate a range of loss for any additional costs related to the Recalled Products that exceed the current estimated liability. We 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 costs related to the Recalled Products. Based on the factors currently known, we believe the appropriate liability has been established at this time. It is reasonably possible that additional costs related to the Recalled Products could be incurred that exceed the estimated liability by amounts that could be material to our Consolidated Financial Statements.

As part of its review of the Paroc insulation product portfolio, the Company discovered potential nonconformances relating to certain ventilation duct insulation products. In January 2024, Paroc suspended sales of the affected insulation products as a precautionary measure while it reviews the potential nonconformances, but has not issued recalls. We expect to incur costs associated with the resolution of this matter. The amount or range of any potential loss cannot be reasonably estimated at this time. The Company is continuing its review.

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 either ISO 14001 certified or deploy environmental management systems based on ISO 14001 principles. 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.

13. CONTINGENT LIABILITIES AND OTHER MATTERS (continued)

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, similar state or local laws pertaining to the management and remediation of hazardous materials and petroleum. The Company became involved in these sites as a result of government action or in connection with business acquisitions. As of June 30, 2024, the Company was involved with a total of 22 sites worldwide, including 9 Superfund and state or country equivalent sites and 13 owned or formerly owned sites. None of the liabilities for these sites are individually significant to the Company.

Remediation activities generally involve a potential range of activities and costs related to soil, groundwater, and sediment contamination. This can include pre-cleanup activities such as fact-finding and investigation, risk assessment, feasibility studies, remedial action design and implementation (where actions may range from monitoring to removal of contaminants, to installation of longer-term remediation systems). A number of factors affect the cost of environmental remediation, including the number of parties involved in a particular site, the determination of the extent of contamination, the length of time the remediation may require, the complexity of environmental regulations, variability in clean-up standards, the need for legal action, and changes in remediation technology. Taking these factors into account, Owens Corning reasonably estimates the costs of remediation to be paid over a period of years. The Company accrues an amount on an undiscounted basis, when a liability is probable and reasonably estimable. Actual cost may differ from these estimates for the reasons mentioned above. At June 30, 2024, the Company had an accrual totaling $4 million for these costs, of which the current portion is $2 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.

During the first quarter of 2024, the Procuraduría Federal de Protección al Ambiente (“PROFEPA”) issued a ruling to Owens Corning Mexico, S. de R.L. de C.V., a subsidiary of the Company (“OC Mexico”), citing violations of Mexico’s air emissions regulations at OC Mexico’s facility in Mexico City, Mexico and imposing monetary sanctions of approximately $1 million. OC Mexico previously performed all related corrective action and, as of the date of this report, is in compliance with applicable federal and local environmental laws. OC Mexico is in the process of appealing PROFEPA’s ruling and the resulting monetary sanctions.

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, 2024, the number of shares remaining available under the 2023 Stock Plan for all stock awards was 3.0 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,
	2024		2023		2024		2023
Total stock-based compensation expense	$	39	$	14	$	53	$	27

Restricted Stock Units

The Company has granted restricted stock units (“RSUs”) under its stockholder-approved stock plans. Generally, 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 to four years. The 2023 Stock Plan allows alternate vesting schedules for death, disability, and retirement. The weighted-average grant date fair value of RSUs granted under the 2023 Stock Plan in 2024 was $154.82.

Masonite Equity Awards

On May 15, 2024, the Company converted outstanding Masonite stock-based incentive awards to Masonite employees at a 0.8 equity award exchange ratio. Masonite equity awards include outstanding and unvested awards of restricted stock units and performance stock units (“PRSUs”) under the Masonite International Corporation 2021 Omnibus Incentive Plan (“Masonite Stock Plan”) that were held by employees of Masonite, which were exchanged for time-vesting restricted stock units of Owens Corning RSUs in connection with the completion of the transactions contemplated by the Arrangement Agreement. The converted stock-based incentive awards include 0.2 million PRSUs and 0.3 million restricted stock units.

The equity award exchange ratio was determined by the consideration amount of $133 per share divided by the volume weighted average closing sale price of one share of Owens Corning common stock for the ten consecutive trading days ended March 15, 2024 of $174.03 per share, in accordance with the terms of the Arrangement Agreement.

In accordance with the Arrangement Agreement, the number of Masonite shares underlying the PRSUs was equal to (i) 107.33% of target for PRSUs granted in February 2022, (ii) 100% of target for PRSUs granted in August 2022 and (iii) 122% of target for PRSUs granted in February 2023.

The fair value of the Owens Corning RSUs issued for Masonite outstanding equity awards was $85 million as of the date of acquisition, of which $35 million was related to pre-combination expense and was included in the purchase price. The remaining portion of $50 million relates to post-combination expense, of which $21 million was accelerated during the quarter. As of June 30, 2024, the future unrecognized expense related to the converted outstanding RSUs was approximately $26 million which will be recognized over the remaining service period of approximately 2 years. Please refer to Note 7 and 10 of the Consolidated Financial Statements for further information. Future equity-based awards to Company employees who were former Masonite employees may be granted from the remaining available shares under the Masonite Stock Plan. At June 30, 2024, the number of shares remaining available under the Masonite Stock Plan was 0.6 million shares of Owens Corning common stock.

The following table summarizes the Company’s RSU activity:



	Number of RSUs		Weighted-Average Fair Value
Balance at December 31, 2023	$	1,225,668	$	79.72
Granted	219,913		154.82
Assumed (converted Masonite equity awards)	488,778		174.03

Forfeited	(21,977)		109.01
Balance at June 30, 2024	$	1,360,748	$	110.38

As of June 30, 2024, there was $80 million of total unrecognized compensation cost related to RSUs. This total includes $26 million of unrecognized compensation related to converted Masonite equity awards and $54 million related to Owens Corning Stock Plans. That cost is expected to be recognized over a weighted-average period of 2.06 years. The total grant date fair value of shares vested during the six months ended June 30, 2024 and 2023 was $64 million and $22 million, respectively.

Performance Share Units

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

In the six months ended June 30, 2024, 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 after 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 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 three-year performance period. Pro-rata vesting may be utilized in the case of death, disability or retirement and awards, if earned, will be paid at the end of the three-year period.

The following table provides a summary of the grant date fair values of the internal Company-based metric PSUs:


	Six Months Ended June 30,
	2024		2023
Grant date fair value of units granted	$	147.18	$	92.97

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 or after 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 2024 and 2023:




	Six Months Ended June 30,
	2024		2023
Expected volatility	33.88%		44.66%
Risk free interest rate	3.94%		3.75%
Expected term (in years)	2.91		2.91
Grant date fair value of units granted	$	195.95	$	119.33

The risk-free interest rate was based on zero-coupon United States Treasury STRIPS 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, 2024, there was $24 million total unrecognized compensation cost related to PSUs. That cost is expected to be recognized over a weighted-average period of 1.92 years.

The following table summarizes the Company’s PSU activity:



	Number of PSUs	Weighted-Average Grant Date Fair Value
Balance at December 31, 2023	268,677	$	100.57

Granted	95,997	161.12
Vested	(9,063)	109.17
Forfeited	(14,058)	103.22
Balance at June 30, 2024	341,553	$	117.25

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, 2024, 3.1 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, 2024, respectively. During the three and six months ended June 30, 2023, the Company recognized expense of $2 million and $4 million, respectively, related to the Company’s ESPP. As of June 30, 2024, there was $3 million of total unrecognized compensation cost related to the ESPP.

Basic	$	3.27	$	3.81	$	6.69	$	8.01
Diluted	$	3.24	$	3.78	$	6.63	$	7.94

For the three and six months ended June 30, 2024 and June 30, 2023, there were no non-vested RSUs or PSUs that had an anti-dilutive effect on earnings per share.

On December 1, 2022, the Board of Directors approved a new share repurchase program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (the “Repurchase Authorization”). The Repurchase Authorization enables the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company’s discretion. The Company repurchased 0.9 million shares of its common stock for $130 million, inclusive of applicable taxes, during the six months ended June 30, 2024, under the Repurchase Authorization. As of June 30, 2024, 8.1 million shares remain available for repurchase under the Repurchase Authorization.

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.

16. INCOME TAXES

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


	Three Months Ended June 30,						Six Months Ended June 30,
	2024			2023			2024			2023
Income tax expense	$	110		$	121		$	198		$	251
Effective tax rate	28		%	26		%	25		%	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, 2024 is primarily due to U.S. state and local income tax expense, foreign rate differential, U.S. federal taxes on foreign earnings and permanently non-deductible expenses both of which were related to the acquisition of Masonite. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the six months ended June 30, 2024 is primarily due to U.S. state and local income tax expense and foreign rate differential partially offset by discrete tax benefits related to valuation allowance and stock-based compensation.

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 Company continues to assert indefinite reinvestment in accordance with ASC 740 based on the laws as of enactment of the tax legislation.

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 residential and commercial building products leader committed to building a sustainable future through material innovation. The Company has four reporting segments: Roofing, Insulation, Doors and Composites. Through these lines of business, the Company manufactures and sells products worldwide. We are a market leader in many of our major product categories.

EXECUTIVE OVERVIEW

Net earnings attributable to Owens Corning were $285 million in the second quarter of 2024, compared to $345 million in the same period of 2023. The Company generated $588 million in adjusted earnings before interest and taxes (“Adjusted EBIT”) for the second quarter of 2024, compared to $534 million in the same period of 2023. 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 2024 earnings before interest and taxes (“EBIT”) performance compared to the same period of 2023 increased $35 million and $20 million in our Roofing and Insulation segments, respectively, and decreased $26 million in our Composites segment. Second quarter of 2024 EBIT for our newly acquired Doors segment was $34 million. Within our Corporate, Other and Eliminations category, General corporate expense and other increased by $9 million.

Cash and cash equivalents were $254 million as of June 30, 2024, compared to $968 million as of June 30, 2023. In the six months ended June 30, 2024, the Company’s operating activities provided $517 million of cash, compared to providing $330 million of cash in the same period in 2023. In the six months ended June 30, 2024, the Company’s investing activities used $3,154 million of cash, compared to using $102 million of cash in the same period in 2023.

On May 15, 2024, the Company acquired all of the outstanding shares of Masonite International Corporation (“Masonite”), a leading global designer, manufacturer, marketer and distributor of interior and exterior doors and door systems, for $3.2 billion. The acquisition was funded primarily with debt proceeds from the 364-Day Credit Facility (as defined below) of $2.8 billion and cash on hand. The acquisition of Masonite's market-leading doors business creates a new growth platform for the Company, strengthening the Company's position in building and construction and expanding its offering of branded residential building products. Masonite's operating results and preliminary purchase price allocation have been included in the Company's newly established Doors reportable segment from May 15, 2024, within the Consolidated Financial Statements. Masonite contributed revenues of $311 million and EBIT of $34 million to the Company for the period from May 15, 2024 to June 30, 2024.

On March 1, 2024, the Company entered into a term loan agreement in an aggregate principal amount of $3.0 billion (the “364-Day Credit Facility”). In May 2024, to fund a portion of the purchase of Masonite, the Company borrowed $2.8 billion using Term SOFR plus a spread on the 364-Day Credit Facility. As a result of the borrowing, the Company incurred approximately $16 million of financing fees which were amortized to Interest expense, net on the Consolidated Statements of Earnings. During the quarter, the Company completely repaid the 364-Day Credit Facility with a combination of issuance of new senior notes, borrowings on the receivables securitization and cash on hand. Based on terms of the agreement, no further amounts can be drawn.

On May 15, 2024, the Company initially borrowed $295 million under the receivables securitization facility (“Receivables Securitization Facility”) which was used to pay down a portion of the 364-Day Credit Facility. Subsequent to the May 15, 2024 borrowing, the Company repaid and re-borrowed on the Receivables Securitization Facility throughout the quarter to pay down portions of the 364-Day Credit facility. As of June 30, 2024, there was a remaining balance on the Receivables Securitization Facility of $155 million.

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

On May 31, 2024, the Company issued $500 million of 2027 senior notes with an annual interest rate of 5.500%, $800 million of 2034 senior notes with an annual interest rate of 5.700% and $700 million of 2054 senior notes with an annual interest rate of 5.950%. These senior notes are net of discounts and issuance costs of $4 million, $11 million and $17 million, respectively. The proceeds from these notes were used to repay a portion of the outstanding borrowings under the 364-Day Credit Facility that was used to fund a portion of the purchase of Masonite in the second quarter of 2024 and to pay related fees and expenses.

On May 1, 2024, in connection with the acquisition of Masonite, we commenced an offer to exchange (the “Exchange Offer”) any and all of Masonite’s outstanding 3.50% Senior Notes due 2030 (the “Masonite 2030 notes”) for new 3.50% Senior Notes due 2030 of Owens Corning (the “Owens Corning 2030 notes”). On May 22, 2024, 99.51% of the outstanding Masonite 2030 notes were exchanged and we issued $373 million of aggregate principal amount of Owens Corning 2030 notes. Following the settlement of the Exchange Offer, approximately $2 million of the Masonite 2030 notes that were not exchanged remain outstanding, which has been recorded on the Consolidated Balance Sheets.

On December 1, 2022, the Board of Directors approved a new share repurchase program under which the Company is authorized to repurchase up to an aggregate of 10 million shares of the Company’s outstanding common stock (the “Repurchase Authorization”). The Repurchase Authorization enables the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company’s discretion. The Company did not repurchase any shares of its common stock during the second quarter of 2024 under the Repurchase Authorization. As of June 30, 2024, 8.1 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 2024, net sales increased $226 million and increased $195 million, respectively, compared to the same periods in 2023. For the second quarter and year-to-date 2024, the increase in net sales was primarily driven by the revenues from our Doors segment as a result of the Masonite acquisition, which was partially offset by lower sales volumes across the Roofing, Insulation and Composites segments. Favorable product mix and higher selling prices within the Roofing and Insulation segments also contributed to the increase.

GROSS MARGIN

In the second quarter and year-to-date 2024, gross margin increased $115 million and increased $206 million, respectively, compared to the same periods in 2023. For the second quarter and year to date 2024, the increase was primarily driven by higher selling prices within Roofing and Insulation and lower manufacturing costs in Roofing and Composites. Favorable product mix and delivery were offset by lower sales volumes across Roofing, Insulation and Composites. Also contributing to the increase were the margins from our Doors segment as a result of the Masonite acquisition.

MARKETING AND ADMINISTRATIVE EXPENSES

In the second quarter and year-to-date 2024, marketing and administrative expenses increased $42 million and increased $50 million, respectively, compared to the same periods in 2023. For the second quarter and year-to-date 2024, the increase was primarily driven by the addition of the Doors segment selling, general and administrative expenses during the quarter and ongoing inflationary pressures throughout the organization.

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, NET

In the second quarter and year-to-date 2024, other expenses increased $97 million and increased $119 million, respectively, compared to the same periods in 2023. For the second quarter and year-to-date 2024, the increase was primarily driven by higher acquisition and strategic review-related costs.

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

INTEREST EXPENSE, NET

In the second quarter and year-to-date 2024, interest expense, net, increased $41 million and increased $36 million, respectively, compared to the same periods in 2023. For the second quarter and year-to-date, the increase was driven by higher interest on the 364-Day Credit Facility and higher long-term debt balances in connection with the Masonite acquisition, slightly offset by higher interest income.

INCOME TAX EXPENSE

Income tax expense for the three and six months ended June 30, 2024 was $110 million and $198 million, respectively. For the second quarter of 2024 and the six months ended June 30, 2024, the Company’s effective tax rate was 28% and 25%, respectively. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the three months ended June 30, 2024 is primarily due to U.S. state and local income tax expense, foreign rate differential, U.S. federal taxes on foreign earnings and permanently non-deductible expenses both of which were related to the acquisition of Masonite. The difference between the effective tax rate and the U.S. federal statutory tax rate of 21% for the six months ended June 30, 2024 is primarily due to U.S. state and local income tax expense and foreign rate differential partially offset by discrete tax benefits related to valuation allowance and stock-based compensation.

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, 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.

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, product line and 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):

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

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.

EBITDA	$	388		$	354		$	689		$	579
EBITDA as a % of net sales	35		%	32		%	33		%	29		%

NET SALES

In our Roofing segment, net sales in the second quarter of 2024 decreased $18 million compared to the same period in 2023 due to lower sales volumes of approximately 9% which more than offset higher selling prices of $55 million and favorable product mix.

For year-to-date 2024, net sales in our Roofing segment increased $44 million compared to the same period in 2023. Lower sales volumes of approximately 5% were more than offset by higher selling prices of $87 million and favorable product mix.

EBIT

In our Roofing segment, EBIT in the second quarter of 2024 increased $35 million compared to the same period in 2023 due to higher selling prices of $55 million, favorable product mix and $3 million of lower manufacturing costs, which were slightly offset by lower sales volumes. Favorable delivery of $4 million was more than offset by input cost inflation.

For year-to-date 2024, EBIT in our Roofing segment increased $112 million compared to the same period in 2023 due to higher selling prices of $87 million, favorable product mix and $24 million of lower manufacturing costs, which were slightly offset by lower sales volumes. Favorable delivery of $10 million was more than offset by input cost inflation.

OUTLOOK

In our Roofing segment, the Company expects residential repair and remodeling activity to remain solid and a stable North American new residential construction market. Other uncertainties that may impact Roofing demand include demand from storms and other weather-related events, 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 to best service the market demand.

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,
	2024			2023			2024			2023

EBITDA	$	234		$	220		$	446		$	427
EBITDA as a % of net sales	26		%	24		%	25		%	23		%

NET SALES

In our Insulation segment, net sales in the second quarter of 2024 increased $11 million compared to the same period in 2023. The increase was driven primarily by higher selling prices of $12 million and favorable product mix, slightly offset by lower sales volumes of approximately 1%.

For year-to-date 2024, net sales in our Insulation segment decreased $4 million compared to the same period in 2023. The decrease was driven primarily by lower sales volumes of approximately 3% partially offset by higher selling prices of $24 million and favorable product and customer mix.

EBIT

In our Insulation segment, EBIT in the second quarter of 2024 increased $20 million compared to the same period in 2023. The increase was driven by higher selling prices of $12 million, favorable delivery of $6 million, and favorable product mix. Lower start-up costs were more than offset by higher operating expenses, inclusive of incremental costs associated with evaluating manufacturing investments. The remaining variance was driven by lower sales volumes and $2 million higher manufacturing costs.

For the year-to-date 2024, EBIT in our Insulation segment increased $25 million compared to the same period in 2023. The increase was driven by higher selling prices of $24 million, $20 million of favorable delivery and input costs, and lower start-up costs which more than offset lower sales volumes, higher manufacturing costs of $9 million, and higher operating expenses, inclusive of incremental costs associated with evaluating manufacturing investments. Favorable product and customer mix were slightly offset by higher production downtime.

OUTLOOK

The outlook for Insulation demand is driven by North American new residential construction and 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 2024, the average Seasonally Adjusted Annual Rate (“SAAR”) of U.S. housing starts was approximately 1.348 million, down from an annual average of approximately 1.447 million starts in the second quarter of 2023.

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

The Company expects the new residential construction market in North America, as well as the commercial and industrial construction markets, to remain stable. However, due to a weaker macro-economic outlook, higher interest rates, and ongoing input cost inflation, the global commercial and industrial construction markets are expected to remain soft temporarily. The Company continues to concentrate on managing costs, capital expenditures and working capital as we evaluate options to expand capacity within our existing manufacturing network.

Doors

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

NET SALES

In our new Doors segment, net sales in the second quarter and year-to-date of 2024 were $311 million, due to the acquisition of Masonite, which was completed on May 15, 2024.

EBIT

In our newly acquired Doors segment, EBIT in the second quarter and year-to-date 2024 were $34 million, due to the acquisition of Masonite, which was completed on May 15, 2024.

OUTLOOK

The outlook for the Doors segment is driven by the residential new construction and residential repair and remodeling markets in North America and Europe. The Company expects the North America residential new construction market to remain stable, with discretionary residential repair and remodeling activity in North America to remain soft. Due to a weaker macro-economic outlook and higher interest rates in Europe, the Company expects these markets to remain challenged. The Company will concentrate on managing costs, capital expenditures and working capital.

NET SALES

In our Composites segment, net sales in the second quarter of 2024 decreased $74 million compared to the same period in 2023. The decrease was driven primarily by lower sales volumes of approximately 6% and lower selling prices of $27 million. The remaining variance was driven by unfavorable customer mix which offset favorable product mix, and $5 million of unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

For year-to-date 2024, net sales in our Composites segment decreased $136 million compared to the same period in 2023. The decrease was driven primarily by lower sales volumes of approximately 6% and lower selling prices of $48 million. The remaining variance was driven by unfavorable customer mix which more than offset favorable product mix, and $5 million of unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

EBIT

In our Composites segment, EBIT in the second quarter of 2024 decreased $26 million compared to the same period in 2023. Lower selling prices of $27 million and higher production downtime of $15 million more than offset lower manufacturing costs of $21 million and $10 million of favorable delivery and input costs. The remaining variance was driven about equally by higher start-up costs of $5 million, lower sales volume and unfavorable customer mix. Favorable product mix was offset by the unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

For the year-to-date 2024, EBIT in our Composites segment decreased $29 million compared to the same period in 2023. Lower selling prices of $48 million, higher production downtime of $26 million and higher start-up costs of $11 million more than offset lower manufacturing costs of $51 million and $26 million of favorable delivery and input costs. The remaining variance was driven about equally by unfavorable customer mix and lower sales volume. Favorable product mix was offset by the unfavorable impact of translating sales denominated in foreign currencies into United States dollars.

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 in a dynamic global environment, as well as competitive pricing pressure. The Company remains focused on managing costs, capital expenditures and working capital.

EBIT

In Corporate, Other and Eliminations, EBIT expenses for the second quarter of 2024 were higher by $92 million compared to the same period in 2023, primarily driven by higher acquisition and strategic review-related costs. For year-to-date 2024, EBIT expenses in Corporate, Other and Eliminations were higher by $302 million primarily driven by the prior-year pre-tax gain on the Santa Clara, California site, as well as higher acquisition-related and strategic review-related costs.

General corporate expense and other for the second quarter of 2024 were higher by $9 million compared to the same period in 2023. For year-to-date, general corporate expense and other were higher by $11 million compared to the same period in 2023.

OUTLOOK

In 2024, we estimate general corporate expenses to be in the range of $255 million and $265 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 $254 million as of June 30, 2024, its Senior Revolving Credit Facility (as defined below) and its Receivables Securitization Facility.

The Company has a $1.0 billion senior revolving credit facility (the “Senior Revolving Credit Facility”) that has been amended from time to time. The Senior Revolving Credit Facility was most recently amended in March 2024 to increase the borrowing limit from $800 million to $1.0 billion and extend the maturity date to March 2029. No other significant terms impacting liquidity were amended.

The Company has a $300 million Receivables Securitization Facility that has been amended from time to time. The Receivables Securitization Facility was most recently amended in March 2024 to increase the borrowing limit from $280 million to $300 million and extend the maturity date to February 2025. No other significant terms impacting liquidity were amended.

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

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


	Balance at June 30, 2024
	Senior Revolving Credit Facility		Receivables Securitization Facility
Facility size or borrowing limit	$	1,000	$	300
Collateral capacity limitation on availability	N/A		—
Outstanding borrowings	—		155
Outstanding letters of credit	4		1
Availability on facility	$	996	$	144

The Receivables Securitization Facility and Senior Revolving Credit Facility mature in February 2025 and March 2029, respectively. 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, 2024.

As of June 30, 2024, the Company had $5.6 billion of total debt. The Company's current portion of long-term debt includes $400 million of 4.200% senior notes due in the fourth quarter of 2024. Additionally, the Company has $155 million of short term debt relating to the outstanding borrowings on the Receivables Securitization Facility.

In the second quarter of 2024, the Company borrowed $2.8 billion using Term SOFR plus a spread on the 364-Day Credit Facility to fund a portion of the purchase of Masonite. As a result of the borrowing, the Company incurred approximately $16 million of financing fees which were amortized to Interest expense, net on the Consolidated Statements of Earnings. During the quarter, the Company completely repaid the 364-Day Credit Facility with a combination of issuance of new senior notes, borrowings on the Receivables Securitization Facility and cash on hand. Based on terms of the agreement, no further amounts can be drawn.

On April 15, 2024, in connection with the acquisition of Masonite, we commenced the Tender Offer to purchase any and all of Masonite's outstanding 5.375% Senior Notes due 2028 (the “Masonite 2028 notes”) with an aggregate value of $501 million. On May 13, 2024, 94.25% of the outstanding Masonite 2028 notes were validly tendered, with Owens Corning making a cash payment on May 16, 2024 of approximately $480 million, inclusive of $7 million of interest and $1 million premium on tender. Following the settlement of the Tender Offer, approximately $29 million of the Masonite 2028 notes that were not tendered remain outstanding, which has been recorded on the Consolidated Balance Sheets. Interest on the Masonite 2028 notes is payable semiannually in arrears on February 1 and August 1 each year.

On May 1, 2024, in connection with the acquisition of Masonite, we commenced the Exchange Offer any and all of Masonite’s outstanding 3.50% Senior Notes due 2030 for new 3.50% Senior Notes due 2030 of Owens Corning. On May 22, 2024, 99.51% of the outstanding Masonite 2030 notes were exchanged and we issued $373 million of aggregate principal amount of Owens Corning 2030 notes. Interest on the notes is payable semiannually in arrears on February 15 and August 15 each year, beginning on August 15, 2024. Following the settlement of the Exchange Offer, approximately $2 million of the Masonite 2030 notes that were not exchanged remain outstanding, which has been recorded on the Consolidated Balance Sheets.

The Company issued $500 million of 2027 senior notes with an annual interest rate of 5.500%, $800 million of 2034 senior notes with an annual interest rate of 5.700% and $700 million of 2054 senior notes with an annual interest rate of 5.950% on May 31, 2024. These senior notes are net of discounts and issuance costs of $4 million, $11 million and $17 million, respectively. The proceeds from these notes were used to repay a portion of the outstanding borrowings under the 364-Day Credit Facility that was used to fund a portion of the purchase of Masonite in the second quarter of 2024 and to pay related fees and expenses.

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, 2024, and December 31, 2023, the Company had $122 million and $114 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.

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

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 the Risk Factors disclosed in Item 1A of the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 (the “2023 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 2023 Form 10-K for more details on these material cash requirements. During the second quarter of 2024, 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.

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

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,
		2024		2023
Cash and cash equivalents		$	254	$	968
Net cash flow provided by operating activities		517		330
Net cash flow used for investing activities		(3,154)		(102)
Net cash flow provided by (used for) financing activities		1,321		(385)
Availability on the Senior Revolving Credit Facility		996		796
Availability on the Receivables Securitization Facility		144		279

Operating activities: Net cash flow provided by operating activities increased by $187 million for the six months ended June 30, 2024 compared to the same period in 2023. The increase in cash provided by operating activities was primarily due to lower decreases in accounts payable and lower increases in accounts receivable when compared to the same period in 2023. These were slightly offset by higher increases in inventory during the period. Increases in operating assets and liabilities resulting from the Masonite acquisition were not included within operating activities.

Investing activities: Net cash flow used for investing activities increased by $3.1 billion for the six months ended June 30, 2024 compared to the same period in 2023. The increase was driven by the Masonite acquisition and lower proceeds from sale of assets in 2024 due to the Q1 2023 sale of the Santa Clara site.

Financing activities: Net cash flow provided by financing activities increased by $1.7 billion for the six months ended June 30, 2024 compared to the same period in 2023. The increase was driven by proceeds from long-term debt and net proceeds from the Receivables Securitization Facility related to the Masonite acquisition, as well as lower treasury stock repurchases. These were slightly offset by payments related to the Tender Offer to purchase Masonite senior notes.

Derivatives

Please refer to Note 4 of the Consolidated Financial Statements.

Fair Value Measurement

Please refer to Notes 4, 7, 11, and 12 of the Consolidated Financial Statements.

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. One of our primary safety measures is the Recordable Incident Rate (“RIR”) as defined by the United States Bureau of Labor Statistics. For the three months ended June 30, 2024, our RIR excluding the impact from our Doors segment as a result of the Masonite acquisition, was 0.46, compared to 0.59 as reported in the same period a year ago. For the six months ended June 30, 2024, our RIR excluding the impact from our Doors segment as a result of the Masonite acquisition, was 0.39 compared to 0.62 as reported in the same period a year ago.
