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.
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.

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.

Collectively, the Company's senior notes above, other than the Masonite 2028 notes or 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 December 31, 2025.
Senior Revolving Credit Facility
On March 15, 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 December 31, 2025.
During the first quarter of 2025, the Company borrowed $30 million under the Senior Revolving Credit Facility, which was subsequently repaid with proceeds from the issuance of CP Notes (as defined below). The Company had no borrowings outstanding and $1.5 billion available under the Senior Revolving Credit Facility as of December 31, 2025.
Receivables Securitization Facility
The receivables securitization facility (the "Receivables Securitization Facility") had a Receivables Purchase Agreement (“RPA”) that was accounted for as secured borrowings in accordance with ASC 860, “Accounting for Transfers and Servicing.” Owens Corning Sales, LLC and Owens Corning Receivables LLC, each a subsidiary of the Company, had an RPA with certain financial institutions. On February 25, 2025, the Company amended and restated the RPA to extend the scheduled maturity date to April 2025. Effective March 31, 2025, the Company terminated the Receivables Securitization Facility and RPA.
Under the RPA, the Company had the ability to borrow at the lenders’ cost of funds, which approximated Term SOFR plus a spread. Alternatively, the Company had the ability to borrow at the higher of the United States prime rate or the Overnight Bank Funding Rate plus a spread. The RPA contained various covenants, including a maximum allowed leverage ratio, that the Company believes are usual and customary for a securitization facility.
Owens Corning Receivables LLC’s sole business consisted of the purchase or acceptance through capital contributions of trade receivables and related rights from Owens Corning Sales, LLC and the subsequent retransfer of or granting of a security interest in such trade receivables and related rights to certain purchasers who were party to the RPA.
During the first quarter of 2025, the Company borrowed $299 million under the Receivables Securitization Facility which was subsequently repaid with proceeds from the issuance of CP Notes.
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 second quarter of 2024, the Company completely repaid the 364-Day Credit Facility with a combination of proceeds from the 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.
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 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.

About Debt Disclosures
Debt disclosures detail a company's borrowing structure — the types of instruments, interest rates, maturity schedule, and covenant restrictions that define its financial obligations and flexibility. This section is essential for assessing refinancing risk, interest rate exposure, and the margin of safety against financial distress.
Key signals: the maturity schedule reveals concentration risk — large maturities within 1-2 years during tight credit markets can force dilutive refinancing or asset sales. Compare the fair value of debt against carrying amount to gauge whether the market views the company's credit risk differently than the balance sheet suggests. Watch covenant compliance disclosures for tightening cushions, especially leverage and interest coverage ratios. Variable-rate debt exposure quantifies sensitivity to interest rate changes. Secured versus unsecured mix affects recovery rates and future borrowing capacity. Compare net debt-to-EBITDA against industry peers and covenant limits to assess financial health.
