The Company has a credit agreement with JPMorgan Chase Bank, N.A., as Administrative Agent, Deutsche Bank Securities, Inc., PNC Bank, Truist Bank and Wells Fargo Bank, N.A., as Syndication Agents, and the lenders party thereto (the Credit Agreement), which provides for an $800 million five-year senior unsecured revolving facility (the Revolving Facility) with a maturity date of December 21, 2029. Borrowings under the Revolving Facility bear interest, at the Company’s option, at rates based upon the Secured Overnight Financing Rate (SOFR) or a base rate, plus, for each rate, a margin determined in accordance with a ratings-based pricing grid. Any outstanding principal amounts, together with interest accrued thereon, are due in full on that maturity date. There were no borrowings outstanding under the Revolving Facility as of June 30, 2025 and December 31, 2024. Available borrowings under the Revolving Facility are reduced by any outstanding letters of credit issued by the Company under the Revolving Facility. At June 30, 2025 and December 31, 2024, the Company had $3 million of outstanding letters of credit issued under the Revolving Facility.

The Credit Agreement requires the Company’s ratio of consolidated net debt-to-consolidated earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), as defined, for the trailing-twelve months (the Ratio) to not exceed 3.50x as of the end of any fiscal quarter, provided that the Company may exclude from the Ratio any debt incurred in connection with certain acquisitions during the quarter or three preceding quarters so long as the Ratio calculated without such exclusion does not exceed 4.00x. Additionally, if no amounts are outstanding under the Revolving Facility or the Company's trade receivable securitization facility (discussed below), consolidated debt, as defined, which includes debt for which the Company is a guarantor, shall be reduced in an amount equal to the lesser of $500 million or the sum of the Company’s unrestricted cash and temporary investments, for purposes of the covenant calculation. The Company was in compliance with the Ratio at June 30, 2025.

The Company, through a wholly-owned special-purpose subsidiary, has a $400 million trade receivable securitization facility (the Trade Receivable Facility) that matures on September 17, 2025. The Trade Receivable Facility, with Truist Bank, Regions Bank, First-Citizens Bank & Trust Company, and certain other lenders that may become a party to the facility from time to time, is backed by eligible trade receivables, as defined. Borrowings are limited to the lesser of the facility limit or the borrowing base, as defined. These receivables are originated by the Company and then sold or contributed to the wholly-owned, special-purpose subsidiary. The Company continues to be responsible for the servicing and administration of the receivables purchased by the wholly-owned, special-purpose subsidiary. Borrowings under the Trade Receivable Facility bear interest at a rate equal to the Adjusted Term Secured Overnight Financing Rate (Adjusted Term SOFR), as defined, plus 0.8%. The Trade Receivable Facility contains a cross-default provision to the Company’s other debt agreements. Subject to certain conditions, including lenders providing the requisite commitments, the Trade Receivable Facility may be increased to a borrowing base not to exceed $500 million. There were no borrowings outstanding under the Trade Receivable Facility as of June 30, 2025 and December 31, 2024.
