​ Debt Classification As of June 30, 2025, we had approximately $4.0 billion of debt maturing within the next 12 months, including (i) $1.5 billion of short-term borrowings under our commercial paper program (net of related discount on issuance); (ii) $1.5 billion of tax-exempt bonds with term interest rate periods that expire within the next 12 months, which is prior to their scheduled maturities; (iii) $500 million of 0.75% senior notes that mature in November 2025 and (iv) $464 million of other debt with scheduled maturities within the next 12 months, including $298 million of tax-exempt bonds. As of June 30, 2025, we have classified $3.0 billion of debt maturing in the next 12 months as long-term because we have the intent and ability to refinance these borrowings on a long-term basis as supported by the forecasted available capacity under our $3.5 billion long-term U.S. and Canadian revolving credit facility (“$3.5 billion revolving credit facility”), as discussed below. The remaining $964 million of debt maturing in the next 12 months is classified as current obligations. Access to and Utilization of Credit Facilities and Commercial Paper Program $3.5 Billion Revolving Credit Facility — Our $3.5 billion revolving credit facility, maturing May 2029, provides us with credit capacity to be used for cash borrowings, to support letters of credit and to support our commercial paper program. The interest rates we pay on outstanding U.S. or Canadian loans are based on the Secured Overnight Financing Rate (“SOFR”) administered by the Federal Reserve Bank of New York or the Canadian Overnight Repo Rate Average (“CORRA”) administered by the Bank of Canada, respectively, plus a spread depending on our senior public debt rating assigned by Moody’s Investors Service, Inc. and Standard and Poor’s Global Ratings. The spread above SOFR or CORRA can range from 0.585% to 1.025% per annum, plus applicable credit adjustments. We also pay certain other fees set forth in the $3.5 billion revolving credit facility agreement, including a facility fee based on the aggregate commitment, regardless of usage. As of June 30, 2025, we had no outstanding borrowings under this facility. We had $1.5 billion of outstanding borrowings (net of related discount on issuance) under our commercial paper program and $224 million of letters of credit issued, both supported by the facility, leaving unused and available credit capacity of $1.8 billion as of June 30, 2025. WM Holdings, a wholly-owned subsidiary of WMI, guarantees all of the obligations under the $3.5 billion revolving credit facility. Commercial Paper Program — We have a commercial paper program that enables us to borrow funds for up to 397 days at competitive interest rates. The rates we pay for outstanding borrowings are based on the term of the notes. The commercial paper program is fully supported by our $3.5 billion revolving credit facility. As of June 30, 2025, we had $1.5 billion of outstanding borrowings (net of related discount on issuance) under our commercial paper program. Other Letter of Credit Lines — As of June 30, 2025, we had utilized $870 million of other uncommitted letter of credit lines with terms maturing through December 2028. Debt Borrowings and Repayments Commercial Paper Program — During the six months ended June 30, 2025, we had cash borrowings of $9.0 billion (net of related discount on issuance) which were used for general corporate purposes and cash repayments of $8.7 billion. Senior Notes — During the six months ended June 30, 2025, we repaid $422 million of 3.125% senior notes upon maturity in March 2025. Senior Notes Exchange Offer – On November 8, 2024, we issued approximately $485 million in aggregate principal amount of unregistered 3.875% Senior Notes due 2029 (the “Restricted Notes”) in a private offer (the “SRCL Exchange Offer”) pursuant to which such notes were exchanged for notes of Stericycle. We entered into a registration rights agreement (the “Registration Rights Agreement”) with the dealer managers of the SRCL Exchange Offer pursuant to which we were obligated to use commercially reasonable efforts to file with the SEC and cause to become effective a registration statement with respect to an offer to exchange the Restricted Notes for registered notes with terms that are substantially identical in all material respects to the Restricted Notes. On June 25, 2025, we completed an offer to exchange the outstanding Restricted Notes for new notes registered pursuant to the Securities Act of 1933, as amended (the “Registered Notes”). The terms of the Registered Notes are substantially identical in all material respects to the terms of the Restricted Notes, except that the Registered Notes will not be subject to restrictions on transfer. Approximately $483 million in aggregate principal amount of the Restricted Notes, or 99%, were tendered and accepted, and a like amount of new Registered Notes were issued. The debt exchange is accounted for as a modification of debt, as the financial terms of the Registered Notes do not differ from the Restricted Notes, and there is no substantial difference between the present value of cash flows under each respective set of notes. ​ Tax-Exempt Bonds — We issued $130 million of tax-exempt bonds in the three months ended June 30, 2025. The proceeds from the issuance of these bonds were deposited directly into a restricted trust fund to be used for the specific purpose for which the money was raised, which is generally to finance expenditures for solid waste disposal and recycling facility construction and development.
