Credit Agreement — On January 31, 2025, we entered into the Second Amended and Restated Credit Agreement with the lenders party thereto and Wells Fargo Bank, National Association, as administrative agent, and the other parties thereto (the “Amended and Restated Credit Agreement”), which amended and restated our Amended and Restated Credit Agreement dated as of March 27, 2018.

On April 24, 2026, we entered into the Assignment and Amendment No. 1 to Second Amended and Restated Credit Agreement, which amended the Amended and Restated Credit Agreement (as amended, the “Credit Agreement”), which, among other things, (i) extended the maturity date for $450 million of revolving credit commitments of certain lenders under the Credit Agreement from January 31, 2030 to January 31, 2031, with the option at our election for two one-year extensions, and (ii) assigned $25 million of the revolving credit commitments from HSBC Bank USA, N.A., to JPMorgan Chase Bank, N.A., in each case, on the terms and subject to the conditions set forth therein. As of June 30, 2026, the commitments under the Amended and Restated Credit Agreement were $500 million, and $450 million of the loans and commitments under the Credit Agreement would mature on January 31, 2031, with the remainder maturing January 31, 2030.

The Credit Agreement contains representations, warranties, affirmative and negative covenants and events of default and associated remedies that we believe are customary for agreements of this nature. We were in compliance with the covenants at June 30, 2026.

As of June 30, 2026, we had no borrowings outstanding under our Credit Agreement. We had $2.3 million in letters of credit outstanding under the Credit Agreement at June 30, 2026 and, as a result, had available borrowing capacity of approximately $498 million under the Credit Agreement at that date.

2015 Reimbursement Agreement — On March 16, 2015, we entered into a Reimbursement Agreement (as amended from time to time, the “2015 Reimbursement Agreement”) with The Bank of Nova Scotia (“Scotiabank”), pursuant to which we may from time to time request that Scotiabank issue an unspecified amount of letters of credit. As of June 30, 2026, we had $27.0 million in letters of credit outstanding under the 2015 Reimbursement Agreement.

2028 Senior Notes, 2029 Senior Notes, 2033 Senior Notes and 2036 Senior Notes — On January 19, 2018, we completed an offering of $525 million in aggregate principal amount of 3.95% senior notes due 2028 (the “2028 Notes”), of which the outstanding amount was fully redeemed on June 4, 2026. On November 15, 2019, we completed an offering of $350 million in aggregate principal amount of 5.15% senior notes due 2029 (the “2029 Notes”). On September 13, 2023, we completed an offering of $400 million in aggregate principal amount of 7.15% senior notes due 2033 (the “2033 Notes”). On May 19, 2026, we completed an offering of $500 million in aggregate principal amount of 6.05% senior notes due 2036 (the “2036 Notes”). The net proceeds before offering expenses from the offering of the 2036 Notes were approximately $496 million, which we used to fully redeem our outstanding 2028 Notes and for general corporate purposes.

The 2029 Notes, 2033 Notes, and 2036 Notes, (together, the “Senior Notes”) are our senior unsecured obligations, which rank equally with all other existing and future senior unsecured debt and will rank senior in right of payment to all other future subordinated debt. The Senior Notes will be effectively subordinated to any of our future secured debt to the extent of the value of the assets securing such debt. In addition, the Senior Notes will be structurally subordinated to the liabilities (including trade payables) of our subsidiaries that do not guarantee the Senior Notes. None of our subsidiaries are currently required to be a guarantor under the

Senior Notes. If our subsidiaries guarantee the Senior Notes in the future, such guarantees (the “Guarantees”) will rank equally in right of payment with all of the guarantors’ future unsecured senior debt and senior in right of payment to all of the guarantors’ future subordinated debt. The Guarantees will be effectively subordinated to any of the guarantors’ future secured debt to the extent of the value of the assets securing such debt.

At our option, we may redeem the 2036 Notes in whole or in part, at any time or from time to time prior to February 15, 2036 at a redemption price equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the 2036 Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points less (b) interest accrued to the date of redemption, and (ii) 100% of the principal amount of the 2036 Notes to be redeemed, plus in either case, accrued and unpaid interest thereon to, but excluding, the redemption date. Additionally, commencing on February 15, 2036, we may redeem the 2036 Notes at our option, in whole or in part, at a redemption price equal to 100% of the principal amount of the 2036 Notes to be redeemed, plus accrued and unpaid interest thereon to, but excluding, the redemption date.

Upon the occurrence of a change of control triggering event, as defined in the indenture governing the 2036 Notes, each holder of the 2036 Notes may require us to purchase all or a portion of such holder’s 2036 Notes at a purchase price in cash equal to 101% of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

On June 4, 2026, we completed our redemption of all the approximately $483 million aggregate principal amount of the outstanding 2028 Notes. The 2028 Notes were redeemed at a redemption price of 100% of the principal amount of the 2028 Notes outstanding, plus accrued and unpaid interest to the redemption date. The total amount of the redemption was approximately $483 million, which was funded using a portion of the net proceeds from our 2036 Notes offering. We recognized a non-cash loss on extinguishment of debt of $0.9 million, primarily related to the write-off of unamortized debt issuance cost associated with the 2028 Notes, which is included in “Interest expense, net of amount capitalized” in the consolidated statement of operations.

The indentures pursuant to which the Senior Notes were issued include covenants that, among other things, limit our and our subsidiaries’ ability to incur certain liens, engage in sale and lease-back transactions or consolidate, merge, or transfer all or substantially all of their assets. These covenants are subject to important qualifications and limitations set forth in the indentures. We were in compliance with these covenants at June 30, 2026. The indentures governing the Senior Notes also contain customary events of default with respect to the Senior Notes. No events of default had occurred at June 30, 2026.
