NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)

1.
GENERAL
Unless the context requires otherwise, the terms “Owens Corning,” “Company,” “we” and “our” in these notes refer to Owens Corning 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, 2025 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, 2025 (the “2025 Form 10-K”). Certain prior year amounts have been reclassified in order to conform to the current year presentation. On February 14, 2025, the Company announced the sale of its glass reinforcements ("GR") business. The transaction represented a strategic shift that has a major effect on the Company's operations and financial results and therefore, beginning with the quarterly report on Form 10-Q for the period ended March 31, 2025 and ending with the close of the transaction, the GR financial results are reflected in the Company’s consolidated financial statements as discontinued operations for all periods presented. Unless otherwise specified, these notes to the Consolidated Financial Statements reflect continuing operations. The Consolidated Statements of Cash Flows present cash flows from both continuing and discontinued operations. Please refer to Note 2 of the Consolidated Financial Statements for further information.
Revenue Recognition
As of June 30, 2026, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $136 million. As of December 31, 2025, our contract liability balances totaled $133 million, of which $24 million was recognized as revenue in the six months ended June 30, 2026. As of December 31, 2024, our contract liability balances (for extended warranties, down payments and deposits, collectively) totaled $118 million, of which $17 million was recognized as revenue in the six months ended June 30, 2025.
Cash, Cash Equivalents and Restricted Cash
The Company defines cash and cash equivalents as cash and time deposits with maturities of three months or less when purchased. Restricted cash primarily represents amounts received from a counterparty related to its performance assurance on an executory contract, and 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. Please refer to Note 16 for additional disclosures related to Supplemental Cash Flow Information.
Accounts Receivable
Our customers consist mainly of distributors, home centers, contractors and retailers. Two of our largest customers accounted for approximately 24% and 22%, respectively, of accounts receivable as of June 30, 2026.
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 our Programs includes a parent guarantee to the participating financial institution for a certain U.S. subsidiary that, at the time of the respective program’s inception in 2015, was a guarantor subsidiary of the Company’s 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.

OWENS CORNING AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)
The Company’s confirmed outstanding obligations under the Programs totaled $176 million and $196 million as of June 30, 2026 and December 31, 2025, respectively. The amounts of invoices paid under the Programs totaled $285 million and $309 million for the six months ended June 30, 2026 and June 30, 2025, respectively.
Pension and Other Postretirement Benefits
The Company sponsors defined benefit pension plans. Under the plans, pension benefits are based on an employee's years of service and, for certain categories of employees, qualifying compensation. Company contributions to these pension plans are determined by an independent actuary to meet or exceed minimum funding requirements.
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.
Accounting for pensions and other postretirement benefits involves estimating the cost of benefits to be provided well into the future and attributing that cost over the time period each employee works. To accomplish this, extensive use is made of assumptions about investment returns, discount rates, inflation, mortality, turnover and medical costs.
Derivative Financial Instruments
The Company is exposed to commodity price, foreign currency exchange rate, and interest rate risks in the normal course of business. The Company’s risk management program uses derivative financial instruments to manage a portion of the volatility associated with these exposures and does not enter into derivatives for trading purposes.
Derivatives designated as cash flow hedges are assessed for effectiveness quarterly. Changes in the fair value of effective cash flow hedges are recorded in Accumulated other comprehensive deficit (“AOCI”) and reclassified into Cost of sales (for commodity hedges) on the Consolidated Statements of Earnings in order to mirror the location of the hedged items impacting earnings. Cash settlements related to commodity cash flow hedges are included in Operating activities in the Consolidated Statements of Cash Flows.
The Company uses foreign exchange forward contracts to manage foreign currency risk associated with certain monetary assets and liabilities recorded on the Consolidated Balance Sheets. Gains and losses from the changes in the fair value of these instruments are recorded in Other (income) expense, net on the Consolidated Statements of Earnings, and are substantially offset by remeasurement impacts on the related foreign currency denominated balance sheet exposures. As of June 30, 2026, the Company had total notional amounts of $142 million for non-designated derivative financial instruments related to foreign currency exposures in U.S. Dollars primarily related to the Mexican Peso, Hong Kong Dollar, Indian Rupee, Chilean Peso and Chinese Yuan. In addition, the Company had notional amounts of $67 million for non-designated derivative financial instruments related to foreign currency exposures in European Euro primarily related to the Polish Złoty, Danish Krone and the Norwegian Krone.
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 anticipated debt issuance. The agreement was designated as a cash flow hedge and was settled in December 2022. Upon settlement, the Company received cash proceeds of $37 million, of which $31 million was deferred into AOCI and is being amortized to Interest expense, net on the Consolidated Statements of Earnings over the term of the Company's 5.700% senior notes due 2034. During the six months ended June 30, 2026, $2 million was recognized in Interest expense, net on the Consolidated Statements of Earnings related to amortization. As of June 30, 2026, $25 million of unrecognized gains related to the rate lock agreement remained in AOCI.
There have been no significant changes in the Company's objectives, strategies, or derivative programs since December 31, 2025. For a complete discussion of the Company's derivative instruments and hedging activities, see Note 5 of the Consolidated Financial Statements within our 2025 Form 10-K.

Accounting Pronouncements
New Pronouncements Adopted
In July 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Updates (“ASU”) 2025-05, "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets," which provides entities with a practical expedient when estimating expected credit losses for current accounts receivable and contract assets arising from transactions accounted for under Accounting Standards Codification ("ASC") 606. The guidance became effective January 1, 2026. We have adopted and determined that this guidance did not have a material effect on our Consolidated Financial Statements.
New Pronouncements Issued
In May 2026, the FASB issued ASU 2026-02, "Environmental Credits and Environmental Credit Obligations (Topic 818)," which establishes recognition, measurement, presentation, and disclosure guidance for environmental credits and related obligations. The new standard provides a comprehensive framework for accounting for environmental credits and environmental credit obligations, an area for which limited guidance previously existed under U.S. GAAP. The guidance is effective January 1, 2028. We are currently assessing the impact adopting this standard will have on our consolidated financial statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.
In December 2025, the FASB issued ASU 2025-11, "Interim Reporting (Topic 270): Narrow-Scope Improvements," which improves the navigability and clarity of the interim reporting guidance. The guidance is effective January 1, 2028. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.
In December 2025, the FASB issued ASU 2025-10, "Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities," which establishes recognition, measurement, and presentation guidance for government grants received by business entities. The guidance is effective January 1, 2029. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.
In November 2025, the FASB issued ASU 2025-09, "Derivatives and Hedging (Topic 815): Hedge Accounting Improvements," which enhances hedge accounting by aligning financial reporting more closely with actual economic risk management and introduces certain targeted refinements. The guidance is effective January 1, 2027. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.
In September 2025, the FASB issued ASU 2025-06, "Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software," which includes targeted improvements to recognition guidance for capitalizing software costs, replacing the previous stage-based model with a principles-based framework. The guidance is effective January 1, 2028. We are currently assessing the impact adopting this standard will have on our Consolidated Financial Statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.
In November 2024, the FASB issued ASU 2024‑03, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220‑40)," which requires enhanced expense‑category disclosures in the notes to the financial statements. In November 2024, the FASB issued ASU 2025‑01, "Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)," which clarifies the effective date of ASU 2024‑03. The guidance is effective January 1, 2027 for the Company, with interim adoption beginning in 2028. We are currently assessing the impact adopting this standard will have on our consolidated financial statement disclosures. We do not believe the adoption of this guidance will have a material effect on our results of operations.

DISCONTINUED OPERATIONS
On February 13, 2025, the Company entered into a definitive agreement ("GR Agreement") for the sale of our GR business, historically reported within the Composites segment, for a purchase price of approximately $436 million, less costs to sell. The GR business manufactured, fabricated, and sold glass fiber reinforcements for a broad range of end markets.
The transaction represented a strategic shift that has a major effect on the Company's operations and financial results. Accordingly, beginning with the quarterly report on Form 10-Q for the period ended March 31, 2025 and ending with the close

Upon classification as held for sale, the Company allocated $98 million of goodwill from the former Composites reporting unit to the discontinued operation based on relative fair values.
On April 14, 2026, the Company entered into an amendment to the GR Agreement ("Amendment") based on changes in market conditions, including a $110 million decrease in the purchase price, the transfer of approximately $32 million in carrying value of additional assets at closing, and the elimination of previously contemplated $225 million seller financing. The Company completed the sale on April 30, 2026 for proceeds of $370 million, net of cash divested and a deposit received at the announcement of the deal. The final proceeds are subject to customary post-closing adjustments.
During the three and six months ended June 30, 2026, the Company recognized a pre-tax gain of $7 million and a pre-tax loss of $175 million, respectively, primarily reflecting the revised transaction terms. The (gain) loss was measured as the excess of the carrying value of the discontinued operation over the fair value of consideration received, less costs to sell, and is presented within Net (loss) earnings from discontinued operations attributable to Owens Corning, net of tax, on the Consolidated Statements of Earnings.
The Company does not expect to recognize material incremental charges related to the transaction, although final amounts remain subject to customary post-closing adjustments.

EARNINGS BEFORE INTEREST, TAXES, DEPRECIATION AND AMORTIZATION
The Company identifies the Chief Executive Officer as the chief operating decision maker ("CODM"). In applying the criteria set forth in the standards for reporting information about segments in financial statements, we have determined that we have three reportable segments – Roofing, Insulation, and Doors. The key factors used to identify these reportable segments are the organization and alignment of our internal operations and the nature of our products. The CODM uses earnings before interest, taxes, depreciation and amortization (“EBITDA”) for each reportable segment to assess segment performance and make decisions on the allocation of resources. Segment EBITDA targets are established on an annual basis and used by the CODM throughout the year to compare with actual results. Quarterly forecasts supplement annual targets and provide incremental information utilized to assess the performance of a segment. Segment EBITDA variance analysis further provides insight into segment operational cost optimization.
The Company does not regularly provide significant segment expense detail to the CODM. EBITDA by segment consists of net sales less related costs and expenses, which are mainly comprised of cost of sales and marketing and administrative costs. EBITDA 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 EBITDA for our reportable segments and are included within Corporate, Other and Eliminations.

Indefinite-Lived Intangible Assets
As of June 30, 2026, there is one indefinite-lived intangible asset that was at an increased risk of impairment. This asset is used by our Doors segment and had a value of $156 million as of June 30, 2026. A change in the estimated long-term revenue growth rate or discount rate for the segment could increase the likelihood of a future impairment.
Definite-Lived 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.
Amortization expense for intangible assets for the three and six months ended June 30, 2026 was $34 million and $68 million, respectively. Amortization expense for intangible assets for the three and six months ended June 30, 2025 was $39 million and $77 million, respectively.

Senior Notes
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. The proceeds from these notes were used to repay a portion of the outstanding borrowings under the 364-Day Credit Facility (as defined below) 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. As of June 30, 2026, the $499 million outstanding balance related to the 2027 senior notes was recorded in Long-term debt – current portion on the Consolidated Balance Sheets.
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 aggregate principal amount of Owens Corning 2030 notes, which was a non-cash financing transaction for the Company. 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.
On April 15, 2024, in connection with the acquisition of Masonite, we commenced a tender offer (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

Collectively, the Company's senior notes above, other than the Masonite 2030 notes, are referred to as the “Senior Notes.” The Senior Notes are general unsecured obligations of the Company and rank pari passu with all existing and future senior unsecured indebtedness of the Company. The Company has the option to redeem all or part of the Senior Notes at any time at a “make-whole” redemption price. The Company is subject to certain covenants in connection with the issuance of the Senior Notes that it believes are usual and customary. The Company was in compliance with these covenants as of June 30, 2026.
Senior Revolving Credit Facility
On March 5, 2025, the Company amended its senior revolving credit facility (the “Senior Revolving Credit Facility”) to increase the available principal amount from $1.0 billion to $1.5 billion and to extend the maturity to March 2030. The Senior Revolving Credit Facility includes both borrowings and letters of credit. Borrowings under the Senior Revolving Credit Facility may be used for general corporate purposes and working capital. The Company has the discretion to borrow under multiple options, which provide for varying terms and interest rates including the United States prime rate, federal funds rate plus a spread or forward-looking term rate based on the Secured Overnight Financing Rate (“Term SOFR”) plus a spread.
The Senior Revolving Credit Facility contains various covenants, including a maximum allowed leverage ratio, that the Company believes are usual and customary for a senior unsecured credit agreement. The Senior Revolving Credit Facility was amended in February 2026 to exclude specified 2025 non‑cash impairment charges from the leverage ratio calculation. The Company was in compliance with the covenants in the Senior Revolving Credit Facility as of June 30, 2026.
Commercial Paper
On March 5, 2025, the Company established a $1.5 billion commercial paper program ("CP Program") for the issuance of unsecured commercial paper notes (the “CP Notes”) with maturities ranging up to 397 days from the date of issuance. The CP Notes may not be voluntarily prepaid or redeemed by the Company prior to maturity and rank pari passu with all existing and future senior unsecured indebtedness of the Company. The proceeds from the CP Notes will be used to finance the Company’s short-term liquidity needs and other general corporate purposes. The Senior Revolving Credit Facility is designated to be a liquidity backstop for the CP Notes outstanding under the CP Program. We do not intend to have outstanding borrowings under the CP Program in excess of available capacity under our Senior Revolving Credit Facility. As of June 30, 2026, there were

As of December 31, 2025, there were $50 million of CP Notes outstanding under the CP Program with a weighted average interest rate and weighted average maturity period of 3.95% and 13 days, respectively. The CP Notes are reported net of any discount and are included within Short-term debt on the Company's Consolidated Balance Sheets.

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"). We do not expect to incur further material charges related to the Recalled Products.
Due to the discovery of these nonconformances, the Company reviewed the Paroc insulation product portfolio. That review has concluded. The review included the Company's assessment of potential nonconformances related to certain ventilation duct and steel beam insulation products. Paroc suspended sales of these affected insulation products but has not issued any recalls. While we expect to incur costs associated with the resolution of the identified ventilation duct and steel beam insulation products, the amount or range of any potential loss cannot be reasonably estimated at this time.
Environmental Matters
The Company has established policies and procedures designed to ensure that its operations are conducted in compliance with all relevant laws and regulations and that enable the Company to meet its high standards for corporate sustainability and environmental stewardship. Our manufacturing facilities are subject to numerous foreign, federal, state and local laws and regulations relating to the presence of hazardous materials, pollution and protection of the environment, including emissions to air, reductions of greenhouse gases, discharges to water, management of hazardous materials, handling and disposal of solid wastes, use of chemicals in our manufacturing processes and remediation of contaminated sites. All Company manufacturing facilities are 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.
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, 2026, the Company was involved with a total of 24 sites worldwide, including 10 Superfund and state or country equivalent sites and 14 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. 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.
Other Matters
As a result of the decision of the U.S. Supreme Court in February 2026, the Company may be entitled to a refund of tariffs previously paid on certain imported products under the International Emergency Economic Powers Act. The Company estimates that approximately $50 million of tariff payments may be eligible for refund as a result of the decision.
During the first six months of June 30, 2026, the Company evaluated the potential refund under ASC 450, Contingencies, and recognized approximately $25 million of the total estimated amount. The Company continues to evaluate the matter and will recognize incremental refunds, if any, when the right to receive such amounts becomes realized or realizable in accordance with ASC 450.

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, 2026, the number of shares remaining available under the 2023 Stock Plan for all stock awards was 2.2 million. 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, 2026, the number of shares remaining available under the Masonite Stock Plan was 0.6 million shares of Owens Corning common stock.
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:

Total stock-based compensation expense$17 $18 $35 $39 
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 years. The Stock Plan allows alternate vesting schedules for death, disability and retirement.

As of June 30, 2026, there was $57 million of total unrecognized compensation cost related to RSUs. That cost is expected to be recognized over a weighted-average period of 1.86 years. The total grant date fair value of stock vested during the six months ended June 30, 2026 and 2025 was $45 million and $48 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 PSUs will vary depending on each award's design and are contingent on meeting the applicable internal performance metrics and external stock performance metrics. PSUs typically vest after a three-year period.
Performance of these metrics is monitored quarterly and if it becomes probable that the internal-based performance goals will not be achieved or will be exceeded, compensation expense recognized will be adjusted and previous 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.
PSUs granted from 2023-2025
The initial fair value for all internal performance metric PSUs is based on the grant date stock price. Internal performance metric PSU grants issued from 2023 through 2025 contained both a service and performance condition. In the six months ended June 30, 2025, the grant date fair value of the granted PSUs was $171.94.
The external-based metric PSUs vest after a three-year period. Outstanding grants issued from 2023 to 2025 are based on the Company’s total stockholder return relative to a peer group. The amount of stock distributed will vary 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 2025:

2025
Expected volatility32.78%
Risk free interest rate4.14%
Expected term (in years)2.90
Grant date fair value of units granted$221.54
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.
PSUs granted in 2026
Beginning in 2026, all PSUs issued are internal performance metric PSUs that are subject to a modifier adjustment based on the Company’s total shareholder return relative to a peer group. The number of shares earned depends on the achievement of both performance and market conditions. The fair value of PSUs granted for the six months ended June 30, 2026 has been estimated at the grant date using a Monte Carlo simulation with various assumptions.

Employee Stock Purchase Plan
The Owens Corning Employee Stock Purchase Plan (“ESPP”) is a tax-qualified plan under Section 423 of the Internal Revenue Code. The purchase price of shares purchased under the ESPP is equal to 85% of the lower of the fair market value of shares of Owens Corning common stock at the beginning or ending of the offering period, which is a six month period ending on May 31 and November 30 of each year. 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, 2026, 2.6 million shares remain available for purchase.
Included in total stock-based compensation is $2 million and $5 million of expense related to the Company's ESPP for each of the three and six months ended June 30, 2026, respectively. During the three and six months ended June 30, 2025, the Company recognized expense of $2 million and $5 million, respectively, related to the Company’s ESPP. As of June 30, 2026, the Company had $4 million of total unrecognized compensation costs related to the ESPP.

Basic earnings per share is calculated by dividing earnings attributable to Owens Corning by the weighted-average number of shares of the Company’s common stock outstanding during the period. Outstanding shares consist of issued shares less treasury stock.
On May 13, 2025, the Board of Directors approved a new share repurchase program under which the Company is authorized to repurchase up to 12 million shares of the Company’s outstanding common stock (the “2025 Repurchase Authorization”). On December 1, 2022, the Board of Directors approved a share repurchase program under which the Company is authorized to repurchase up to 10 million shares of the Company’s outstanding common stock (together with the 2025 Repurchase Authorization, the "Repurchase Authorizations"). The Repurchase Authorizations enable the Company to repurchase shares through the open market, privately negotiated, or other transactions. The actual number of shares repurchased will depend on timing, market conditions and other factors and will be at the Company’s discretion.
The Company repurchased 1.7 million shares of its common stock for $201 million, inclusive of applicable taxes, during the six months ended June 30, 2026 under the Repurchase Authorizations. As of June 30, 2026, 10.8 million shares remained available for repurchase under the Repurchase Authorizations. The Company repurchased 2.3 million shares of its common stock for $322 million, inclusive of applicable taxes, during the six months ended June 30, 2025.
For the three months ended June 30, 2026, the Company had 0.3 million of unvested RSUs and unvested PSUs that had a potentially anti-dilutive effect on earnings per share and were excluded from the computation of diluted earnings per share for the period. For the six months ended June 30, 2026 and each of the three and six months ended June 30, 2025, the Company did not have any unvested RSUs and unvested PSUs that had a potentially anti-dilutive effect on earnings per share.

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 branded building products leader with three complementary businesses providing roofing, insulation and doors primarily for residential markets in North America and Europe. As described below, the Company has three reportable segments: Roofing, Insulation and Doors. Through these lines of business, the Company manufactures and sells products that provide durable, sustainable and energy-efficient solutions. We are a market leader in many of our major product categories.
EXECUTIVE OVERVIEW
Net earnings from continuing operations attributable to Owens Corning were earnings of $310 million in the second quarter of 2026, compared to earnings of $334 million in the second quarter of 2025. The Company generated $660 million in adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) from continuing operations in the second quarter of 2026, compared to $703 million in the second quarter of 2025. See the Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization From Continuing Operations section of the MD&A for further information regarding Adjusted EBITDA from continuing operations, including the reconciliation to Net earnings from continuing operations attributable to Owens Corning. Second quarter of 2026 segment earnings before interest, taxes, depreciation and amortization (“EBITDA”) performance compared to the second quarter of 2025 decreased $16 million in our Roofing segment, decreased $12 million in our Insulation segment and decreased $18 million in our Doors segment. Within our Corporate, Other and Eliminations category, General corporate expenses and other increased by $3 million.
Glass Reinforcements Divestiture
On February 13, 2025, the Company entered into a definitive agreement ("GR Agreement") for the sale of our global glass reinforcements ("GR") business, historically reported within the Composites segment, for a purchase price of approximately $436 million, less costs to sell. The GR business manufactured, fabricated, and sold glass fiber reinforcements for a broad range of end markets.
The transaction represented a strategic shift that has a major effect on the Company's operations and financial results. Accordingly, beginning with the quarterly report on Form 10-Q for the period ended March 31, 2025 and ending with the close of the transaction, the financial results of the GR business are reflected in the Company’s consolidated financial statements as discontinued operations for all periods presented.
Upon classification as held for sale, the Company allocated $98 million of goodwill from the former Composites reporting unit to the discontinued operation based on relative fair values.
On April 14, 2026, the Company entered into an amendment to the GR Agreement ("Amendment") based on changes in market conditions, including a $110 million decrease in the purchase price, the transfer of approximately $32 million in carrying value of additional assets at closing, and the elimination of previously contemplated $225 million seller financing. The Company completed the sale on April 30, 2026 for proceeds of $370 million, net of cash divested and a deposit received at the announcement of the deal. The final proceeds are subject to customary post-closing adjustments. The sale completed Owens Corning’s review of strategic alternatives for the business, announced on February 9, 2024, and aligns with the strategy to reshape the Company to focus on residential and commercial building products in North America and Europe.
During the three and six months ended June 30, 2026, the Company recognized a pre-tax gain of $7 million and a pre-tax loss of $175 million, respectively, primarily reflecting the revised transaction terms. The loss was measured as the excess of the carrying value of the discontinued operation over the fair value of consideration received and is presented within Net (loss) earnings from discontinued operations attributable to Owens Corning, net of tax, on the Consolidated Statements of Earnings.
The Company does not expect to recognize material incremental charges related to the transaction, although final amounts remain subject to customary post-closing adjustments.

Tariff and Trade Uncertainties
Beginning in the first quarter of 2025, the U.S. government announced additional tariffs on goods imported into the U.S. from numerous countries and multiple nations have responded with reciprocal tariffs and other actions. Following the decision of the U.S. Supreme Court in the first quarter of 2026, the Company may be entitled to a refund of tariffs previously paid on certain imported products under the International Emergency Economic Powers Act. The Company estimates that approximately $50 million of tariff payments may be eligible for refund as a result of the decision. During the six months ended June 30, 2026, $25 million of the total estimated amount was recognized within Cost of sales.
The Company continues to monitor the impact of evolving trade policies and tariff programs.
Based on current tariff policies, the Company expects to partially offset the operating profit impact of enacted tariffs through mitigation actions, including supply chain adjustments and productivity and cost savings actions. However, additional tariffs, changes in trade policies or retaliatory measures by foreign governments, or the Company's inability to fully offset related impacts could adversely affect demand for our products, revenue, profitability and cash flows.

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
Net sales increased $9 million and decreased $256 million in the second quarter and year-to-date 2026, respectively, compared to the same periods in 2025. For the second quarter, the increase was primarily driven by higher volumes in the Insulation segment and the favorable impact from translating sales denominated in foreign currencies into United States dollars, which was mostly offset by the unfavorable impact of divestitures in the Insulation and Doors segments. Year-to-date, the decrease was primarily driven by lower volumes in the Roofing and Doors segments and the unfavorable impact of divestitures, which was partially offset by the favorable impact from translating sales denominated in foreign currencies into United States dollar.
GROSS MARGIN
Gross margin decreased $65 million and decreased $280 million in the second quarter and year-to-date 2026, respectively, compared to the same periods in 2025. For the second quarter, higher delivery costs, input cost inflation net of tariff recovery, and the impact of production downtime were partially offset by higher volumes in the Insulation segment and favorable mix. Year-to-date, the decrease was primarily driven by lower sales volumes in the Doors and Roofing segments, input cost inflation, the impact of production downtime, higher delivery costs and lower selling prices.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)
MARKETING AND ADMINISTRATIVE EXPENSES
Marketing and administrative expenses decreased $11 million and decreased $14 million in the second quarter and year-to-date 2026 compared to the same periods in 2025, respectively. For the second quarter and year-to-date 2026, the decrease was primarily driven by lower marketing spend and labor expenses due to cost control initiatives.
OTHER EXPENSE, NET
Other expense, net decreased $5 million and increased $70 million in the second quarter and year-to-date 2026 compared to the same periods in 2025, respectively. For the second quarter, the decrease was primarily driven by lower acquisition-related transaction costs and gain related to the sale of a site that was part of a previous restructuring action in the Roofing segment. For year-to-date, the increase was primarily driven by higher restructuring costs and an increase in the liability for the Paroc marine recall.
INTEREST EXPENSE, NET
Interest expense, net increased $6 million and increased $8 million in the second quarter and year-to-date 2026 compared to the same periods in 2025, respectively. For the second quarter and year-to-date 2026, the increase was driven by lower interest income, partially offset by lower interest on commercial paper balances.
INCOME TAX EXPENSE
Income tax expense for the three and six months ended 2026 was $102 million and $117 million, respectively. The Company’s effective tax rate for the second quarter 2026 and the six months ended June 30, 2026 was 25%. The difference between the 25% effective tax rate and the U.S. federal statutory tax rate of 21% is primarily due to U.S. state and local income tax expense and foreign tax effects.
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 2025 was $110 million and $198 million, respectively. The Company’s effective tax rate for the second quarter 2025 and the six months ended June 30, 2025 was 25%. The difference between the 25% effective tax rate and the U.S. federal statutory tax rate of 21% is primarily due to U.S. state and local income tax expense and foreign rate differential.
Restructuring Costs
The Company has incurred restructuring and other exit costs in connection with its global cost reduction, product line and productivity initiatives. These costs are recorded within Corporate, Other and Eliminations. Please refer to Note 9 of the Consolidated Financial Statements for further information on the nature of these costs.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)
Adjusted Earnings Before Interest, Taxes, Depreciation and Amortization From Continuing Operations
Adjusted EBITDA from continuing operations 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 EBITDA from continuing operations 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 from continuing operations attributable to Owens Corning as prepared in accordance with accounting principles generally accepted in the United States.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)
Segment Results
EBITDA by segment consists of net sales, less related costs and expenses plus depreciation and amortization. EBITDA 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 EBITDA for our reportable segments and are included in the Corporate, Other and Eliminations category, which is presented following the discussion of our reportable segments. Segment EBITDA is the principal measure used by the chief operating decision maker ("CODM") to assess segment performance and make decisions on the allocation of resources.
Roofing
The table below provides a summary of net sales and EBITDA for the Roofing segment:

EBITDA$441 $457 $672 $789 
EBITDA as a % of net sales34 %35 %30 %33 %
NET SALES
In our Roofing segment, net sales increased $10 million in the second quarter 2026 compared to the second quarter 2025. Lower volumes of approximately 1% were more than offset by favorable mix, a $3 million favorable impact from translating sales denominated in foreign currencies into United States dollars, and relatively flat selling prices.
For year-to-date 2026, net sales in our Roofing segment decreased $150 million compared to the same period in 2025. Lower volumes of approximately 7% and lower selling prices of $11 million were slightly offset by favorable mix and the favorable impact from translating sales denominated in foreign currencies into United States dollars.
EBITDA
In our Roofing segment, EBITDA decreased $16 million in the second quarter 2026 compared to the second quarter 2025. The decrease was primarily driven by higher delivery costs of $23 million and input cost inflation of $19 million, partially offset by favorable mix and lower manufacturing costs of $11 million. The remaining variance was driven by the impact of production downtime, lower volumes, and relatively flat selling prices.
For year-to-date 2026, EBITDA in our Roofing segment decreased $117 million compared to the same period in 2025. The decrease was primarily driven by lower volumes, input cost inflation of $25 million, and higher delivery costs of $23 million. The remaining variance was driven by lower selling prices of $11 million, the impact of production downtime, and higher manufacturing costs of $6 million, which were partially offset by favorable mix.
OUTLOOK
In our Roofing segment, the Company expects non-discretionary roof replacement activity to remain solid in the near-term. The Company expects seasonal storm demand to be in line with historical averages, but the impact of heavier inventory restocking in the second quarter is expected to reduce purchases in the third quarter. The Company expects global non-residential construction markets to be relatively stable in the near-term. The Company will continue to focus on managing costs, capital expenditures and working capital to best service the market demand.

NET SALES
In our Insulation segment, net sales increased $37 million in the second quarter 2026 compared to the second quarter 2025. Higher volumes of 7% and a $14 million favorable impact from translating sales denominated in foreign currencies into United States dollars were partially offset by the unfavorable impact from the divestiture of our building materials business in China and Korea and lower selling prices of $11 million.
For year-to-date 2026, net sales in our Insulation segment decreased $5 million compared to the same period in 2025. The unfavorable impact from the divestiture of our building materials business in China and Korea and lower selling prices of $32 million were partially offset by higher volumes of 2%. The remaining variance was driven by a $39 million favorable impact from translating sales denominated in foreign currencies into United States dollars and favorable mix.
EBITDA
In our Insulation segment, EBITDA decreased $12 million in the second quarter 2026 compared to the second quarter 2025. Higher volumes and favorable manufacturing costs were more than offset by input cost inflation of $19 million, the impact of production downtime of $15 million, lower selling prices of $11 million, and higher delivery costs.
For year-to-date 2026, EBITDA in our Insulation segment decreased $70 million compared to the same period in 2025. The decrease was primarily driven by the impact of production downtime of $35 million, lower selling prices of $32 million, input cost inflation of $30 million and higher delivery costs, which were partially offset by higher volumes, lower manufacturing costs, and slightly favorable mix.
OUTLOOK
The outlook for Insulation demand is driven by North American new residential construction, remodeling and repair activity, as well as non-residential construction activity in the United States, Canada, Europe and Latin America. Demand in non-residential insulation markets is most closely correlated to industrial production growth and overall economic activity in the markets we serve. Demand for residential insulation is most closely correlated to U.S. housing starts.
During the second quarter of 2026, the average Seasonally Adjusted Annual Rate (“SAAR”) of U.S. housing starts was 1.347 million starts, which was up from 1.327 million starts in the second quarter of 2025.
The Company expects the new residential construction market in North America to remain challenged in the near-term, driven by affordability challenges and consumer uncertainty. The global non-residential construction markets are expected to be relatively stable in the near-term. The Company continues to concentrate on driving productivity, managing costs, capital expenditures and working capital as we position ourselves to expand capacity within our existing manufacturing network.

EBITDA as a % of net sales11 %14 %9 %13 %
NET SALES
In our Doors segment, net sales decreased $41 million in the second quarter 2026 compared to the second quarter 2025 due to lower volumes of 3%, primarily driven by the exit of our Prineville, Oregon facility, a $19 million unfavorable impact from the divestiture of our distribution business and slightly unfavorable mix.
For year-to-date 2026, net sales in our Doors segment decreased $106 million compared to the same period in 2025, primarily due to lower volumes of 8% and a $29 million unfavorable impact from the divestiture of our distribution business. This was partially offset by a $6 million favorable impact of translating sales denominated in foreign currencies into United States dollars and slightly favorable mix.
EBITDA
In our Doors segment, EBITDA decreased $18 million in the second quarter 2026 compared to the second quarter 2025. Higher delivery costs of $11 million, lower volumes, higher manufacturing costs of $7 million, and unfavorable mix were partially offset by $8 million of lower selling, general and administrative costs and lower input cost inflation of $7 million, which includes the impact of tariff refunds.
For year-to-date 2026, EBITDA in our Doors segment decreased $52 million compared to the same period in 2025. The decrease was primarily driven by lower volumes, higher manufacturing costs of $16 million and higher delivery costs of $11 million. Lower selling, general and administrative costs of $17 million were offset by the impact of production downtime, unfavorable mix, and input cost inflation of $3 million, which includes the impact of tariff refunds.
OUTLOOK
The outlook for the Doors segment is driven by the new residential construction and residential repair and remodeling markets in North America and Europe. The Company expects the North America residential new construction market to remain challenged in the near-term, with discretionary residential repair and remodeling activity in North America remaining soft. The Company will concentrate on managing costs, capturing synergies, capital expenditures and working capital.
Corporate, Other and Eliminations
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 EBITDA for our reportable segments and are included within Corporate, Other and Eliminations.

EBITDA
The impact on EBITDA from Corporate, Other and Eliminations was $26 million lower and $53 million higher in the second quarter and year-to-date 2026 compared to the same periods in 2025, respectively. For the second quarter, the decrease was primarily driven by the loss on sale of business in the prior year. For year-to-date, the increase primarily driven by higher restructuring costs and an increase in the liability for the Paroc marine recall, partially offset by the loss on sale of business in the prior year.
General corporate expense and other was $3 million lower and remained flat in the second quarter and year-to-date 2026 compared to the same periods in 2025, respectively.
OUTLOOK
In 2026, we expect general corporate expenses to be approximately $245 million to $255 million.
LIQUIDITY, CAPITAL RESOURCES AND OTHER RELATED MATTERS
Liquidity
The Company's primary sources of liquidity are its balance of Cash and cash equivalents from continuing operations of $271 million as of June 30, 2026, its commercial paper program ("CP Program") and Senior Revolving Credit Facility (as defined below).
The Company has a $1.5 billion senior revolving credit facility (the “Senior Revolving Credit Facility”) that has been amended from time to time. The Senior Revolving Credit Facility was amended in March 2025 to increase the borrowing limit from $1.0 billion to $1.5 billion and extend the maturity date to March 2030. No other significant terms impacting liquidity were amended.
The agreement governing our Senior Revolving Credit Facility contains various covenants that we believe are usual and customary. These covenants include a maximum allowed leverage ratio. The Senior Revolving Credit Facility was amended in February 2026 to exclude specified 2025 non‑cash impairment charges from the leverage ratio calculation. We were in compliance with the covenants in the Senior Revolving Credit Facility as of June 30, 2026.
On March 5, 2025, the Company established the CP Program for the issuance of $1.5 billion in unsecured commercial paper notes (the "CP Notes") with maturities up to 397 days from the date of issuance. We do not intend to have outstanding commercial paper borrowings in excess of available capacity under the Senior Revolving Credit Facility.
38

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, 2025 (the “2025 Form 10-K”) for details on the factors that could inhibit our subsidiaries' abilities to pay dividends or make other distributions to the parent company.
Cash Flows
Cash and cash equivalents were $271 million as of June 30, 2026, compared to $265 million as of June 30, 2025. 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, 2026 and December 31, 2025, the Company had $144 million and $97 million, respectively, in cash and cash equivalents in certain of its foreign subsidiaries. The Company continues to assert indefinite reinvestment for certain of its continuing operations in accordance with Accounting Standards Codification (“ASC”) 740 based on the laws as of enactment of the tax legislation.
Operating activities: Net cash flow provided by operating activities decreased by $34 million for the six months ended June 30, 2026 compared to the same period in 2025. The decrease was primarily due to lower cash earnings, partially offset by the change in working capital. For the six months ended June 30, 2026, there was no depreciation and amortization related to discontinued operations.
Investing activities: Net cash flow provided by investing activities increased by $354 million for the six months ended June 30, 2026 compared to the same period in 2025. The increase was primarily driven by the proceeds from the sale of GR business, partially offset by higher cash paid for property, plant and equipment. For the six months ended June 30, 2026, cash paid for property, plant and equipment related to discontinued operations was $28 million.
Financing activities: Net cash flow used for financing activities increased by $254 million for the six months ended June 30, 2026 compared to the same period in 2025. The increase was primarily driven by lower net proceeds from CP Notes, partially offset by lower treasury stock repurchases in the current year.
Material Cash Requirements
Our anticipated uses of cash include capital expenditures, working capital needs, share repurchases, meeting financial obligations including repayment of senior notes maturing in the next twelve months, 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, our CP Program and access to credit markets will provide ample liquidity to enable us to meet our cash requirements for at least the next twelve months and foreseeable future thereafter.
Please refer to Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in the 2025 Form 10-K for more details on these material cash requirements. During the second quarter of 2026, there have been no material changes to our expected uses of cash and contractual obligations.
Debt
As of June 30, 2026, the Company had $5.2 billion of total debt. The Company's current portion of long-term debt primarily relates to $899 million of the current portion of 3.400% senior notes maturing in the third quarter of 2026 and 5.500% senior notes maturing in the second quarter of 2027. Further discussion of the amount and timing of the future scheduled maturities of our senior notes can be found in Note 10 of the Consolidated Financial Statements. As of June 30, 2026, the Company's Short-term debt includes $65 million of CP Notes.
On March 5, 2025, the Company amended the Senior Revolving Credit Facility to increase the available principal amount from $1.0 billion to $1.5 billion and to extend the maturity to March 2030. The Company had no borrowings outstanding and $1.5 billion available under the Senior Revolving Credit Facility as of June 30, 2026.
On March 5, 2025, the Company established a CP Program for the issuance of CP Notes with maturities ranging up to 397 days from the date of issuance. As of June 30, 2026, there were $65 million of CP Notes outstanding under the CP Program with a weighted average interest rate and weighted average maturity period of 4.00% and 5 days, respectively. We do not intend to have outstanding borrowings under the CP Program in excess of available capacity under our Senior Revolving Credit Facility.

ITEM 2.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (continued)
Supplier Finance Programs
We review supplier terms and conditions on an ongoing basis, and have negotiated payment terms extensions in recent years in connection with our efforts to reduce working capital and improve cash flow. Separate from those terms extension actions, certain of our subsidiaries have entered into paying agency agreements with third-party administrators. These voluntary supply chain finance programs (collectively, the “Programs”) generally give participating suppliers the ability to sell, or otherwise pledge as collateral, their receivables from the Company to the participating financial institutions, at the sole discretion of both the suppliers and financial institutions. The Company is not a party to the arrangements between the suppliers and the financial institutions. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by the suppliers’ decisions to sell, or otherwise pledge as collateral, amounts under these arrangements. 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 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 roll-forward of outstanding obligations under the supplier finance programs.
Derivatives
Please refer to Note 5 in the Company's 2025 Form 10-K for additional information.
Fair Value Measurement
Please refer to Notes 1 and 10 of the Consolidated Financial Statements.
SAFETY
Working safely is an expectation at Owens Corning. We believe this organization-wide expectation provides for a safer work environment for employees, improves our manufacturing processes, reduces our costs and enhances our reputation. Furthermore, striving to be a world-class leader in safety provides a platform for all employees to understand and apply the resolve necessary to be a high-performing, global organization. One of our primary safety measures is the Recordable Incidence Rate (“RIR”) as defined by the United States Bureau of Labor Statistics. For the three months ended June 30, 2026, our RIR was 0.75, compared to 0.60 in the same period a year ago. For the six months ended June 30, 2026, our RIR was 0.65, compared to 0.58 in the same period a year ago.
