(a)See the 2024 Form 10-K, including note 7 to the consolidated financial statements, for additional information regarding the maturity and principal amortization provisions and interest rates relating to the Company's indebtedness.
(b)Represents the weighted-average stated interest rate, as applicable.
(c)In May 2025, the Company paid in full the previously outstanding Tower Revenue Notes, Series 2015-2 on the anticipated repayment date.
(d)If the $750 million aggregate principal amount of 4.241% senior secured tower revenue notes ("Tower Revenue Notes, Series 2018-2") is not paid in full on or prior to July 2028, the anticipated repayment date, then Excess Cash Flow (as defined in the indenture) of the issuers of such notes will be used to repay the principal, and additional interest (of an approximately 5% per annum) will accrue. The Tower Revenue Notes, Series 2018-2 are prepayable at par if voluntarily repaid within eighteen months of maturity; earlier prepayment may require additional consideration.
(e)The Company's installment purchases primarily relate to land and bear interest rates up to 8% and mature in periods ranging from less than one year to approximately 20 years.
(f)For the periods ended June 30, 2025 and December 31, 2024, reflects $7 million and $8 million, respectively, in finance lease obligations (primarily related to vehicles).
(g)As of June 30, 2025, the undrawn availability under the Company's senior unsecured revolving credit facility ("2016 Revolver") was $6.6 billion.
(h)Both the 2016 Revolver and the senior unsecured term loan A facility ("2016 Term Loan A" and, collectively, "2016 Credit Facility") bear interest, at the Company's option, at either (1) Term SOFR plus (i) a credit spread adjustment of 0.10% per annum and (ii) a credit spread ranging from 0.875% to 1.750% per annum or (2) an alternate base rate plus a credit spread ranging from 0.000% to 0.750% per annum, in each case, with the applicable credit spread based on the Company's senior unsecured debt rating. The Company pays a commitment fee ranging from 0.080% to 0.300%, based on the Company's senior unsecured debt rating, per annum on the undrawn available amount under the 2016 Revolver. See the 2024 Form 10-K, including note 7 to the consolidated financial statements, for information regarding potential adjustments to such percentages.
(i)The maturities of the short-term, unsecured commercial paper notes ("Commercial Paper Notes"), when outstanding, may vary but may not exceed 397 days from the date of issue, but there were no Commercial Paper Notes issued or outstanding during the period that had original maturities greater than three months. The Commercial Paper Notes are issued under customary terms in the commercial paper market and are issued at a discount from par or, alternatively, can be issued at par and bear varying interest rates on a fixed or floating basis. At any point in time, the Company intends to maintain available commitments under its 2016 Revolver in an amount at least equal to the amount of Commercial Paper Notes outstanding. While any outstanding Commercial Paper Notes generally have short-term maturities, the Company classifies the outstanding issuances, when applicable, as long-term based on its ability and intent to refinance the outstanding issuances on a long-term basis.
(j)In July 2025, the Company repaid in full the 1.350% Senior Notes (as defined below) on the contractual maturity date.
