The Senior Credit Agreement On January 25, 2024, the Company, through its wholly owned subsidiary SBA Senior Finance II, amended and restated its Senior Credit Agreement to (1) issue a new $2.3 billion Term Loan, (2) increase the total commitments under its Revolving Credit Facility from $1.5 billion to $1.75 billion, (3) extend the maturity date of its Revolving Credit Facility to January 25, 2029, and (4) amend certain other terms and conditions under the Senior Credit Agreement. On February 23, 2024 the Company, through its wholly owned subsidiary, SBA Senior Finance II LLC, further increased the total commitments under the Revolving Credit Facility from $1.75 billion to $2.0 billion. On October 2, 2024, the Company, through its wholly owned subsidiary, SBA Senior Finance II, amended its Senior Credit Agreement to (1) reduce the stated rate of interest of the Initial Term Loans from, at SBA Senior Finance II’s election, the Base Rate plus 100 basis points or Term SOFR plus 200 basis points to, at SBA Senior Finance II’s election, the Base Rate plus 75 basis points or Term SOFR plus 175 basis points, and (2) amend certain other terms and conditions under the Senior Credit Agreement. Terms of the Senior Credit Agreement The Senior Credit Agreement requires SBA Senior Finance II to maintain specific financial ratios, including (1) a ratio of Consolidated Net Debt to Annualized Borrower EBITDA not to exceed 6.5 times for any fiscal quarter, (2) a ratio of Consolidated Net Debt (calculated in accordance with the Senior Credit Agreement) to Annualized Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.5 times for 30 consecutive days and (3) a ratio of Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Senior Credit Agreement) of not less than 2.0 times for any fiscal quarter. The Senior Credit Agreement contains customary affirmative and negative covenants that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. The Senior Credit Agreement is also subject to customary events of default. Pursuant to the Second Amended and Restated Guarantee and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loans and certain hedging transactions that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Senior Credit Agreement) with lenders or their affiliates are secured by a first lien on the membership interests of SBA Telecommunications, LLC, SBA Senior Finance, LLC and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real property) of SBA Senior Finance II and the Subsidiary Guarantors. The Senior Credit Agreement permits SBA Senior Finance II, without the consent of the other lenders, to request that one or more lenders provide SBA Senior Finance II with increases in the Revolving Credit Facility or additional term loans provided that after giving effect to the proposed increase in Revolving Credit Facility commitments or incremental term loans the ratio of Consolidated Net Debt to Annualized Borrower EBITDA would not exceed 6.5 times. SBA Senior Finance II’s ability to request such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions set forth in the Senior Credit Agreement including compliance, on a pro forma basis, with the financial covenants and ratios set forth therein and, with respect to any additional term loan, an increase in the margin on existing term loans to the extent required by the terms of the Senior Credit Agreement. Upon SBA Senior Finance II’s request, each lender may decide, in its sole discretion, whether to increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional term loans and, if so, upon what terms. As of December 31, 2024, SBA Senior Finance II was in compliance with the financial covenants contained in the Senior Credit Agreement. Revolving Credit Facility under the Senior Credit Agreement The Revolving Credit Facility consists of a revolving loan under which up to $2.0 billion aggregate principal amount may be borrowed, repaid and redrawn, based upon specific financial ratios and subject to the satisfaction of other customary conditions to borrowing through the maturity date of January 25, 2029. Amounts borrowed under the Revolving Credit Facility accrue interest, at SBA Senior Finance II’s election, at either (1) the Eurodollar Rate or Term SOFR Rate plus a margin that ranges from 112.5 basis points to 150.0 basis points or (2) the Base Rate plus a margin that ranges from 12.5 basis points to 50.0 basis points, in each case based on the ratio of Consolidated Net Debt to Annualized Borrower EBITDA, calculated in accordance with the Senior Credit Agreement. In addition, SBA Senior Finance II is required to pay a commitment fee of between 0.15% and 0.25% per annum on the amount of unused commitment. Furthermore, the Revolving Credit Facility incorporates sustainability-linked targets which will adjust the Revolving Credit Facility’s applicable interest and commitment fee rates upward or downward based on how the Company performs against those targets. Borrowings under the Revolving Credit Facility may be used for general corporate purposes. SBA Senior Finance II may, from time to time, borrow from and repay the Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of the period may not be reflective of the total amounts outstanding during such period. The key terms of the Revolving Credit Facility are as follows:
|  |  |  | Unused
|  | Interest Rate |  | Commitment
|  | as of |  | Fee as of
|  | December 31, 2024 (1) |  | December 31, 2024 (2)
Revolving Credit Facility |  | 5.407% |  | 0.140%
(1) (1)The rate reflected includes a 0.050% reduction in the applicable spread as a result of meeting certain sustainability-linked targets as of December 31, 2023. (2)The rate reflected includes a 0.010% reduction in the applicable commitment fee as a result of meeting certain sustainability-linked targets as of December 31, 2023. ‎ The table below summarizes the Company’s Revolving Credit Facility activity during the years ended December 31, 2024 and 2023 (in thousands):

Term Loan under the Senior Credit Agreement 2024 Term Loan On January 25, 2024, the Company, through its wholly owned subsidiary, SBA Senior Finance II, issued a term loan (the “2024 Term Loan”) under the amended and restated Senior Credit Agreement. The 2024 Term Loan consists of a senior secured term loan with an initial aggregate principal amount of $2.3 billion that matures on January 25, 2031. The 2024 Term Loan (as amended on October 2, 2024) accrues interest, at SBA Senior Finance II's election, at either the Base Rate (with a zero Base Rate floor) plus 75 basis points or at Term SOFR (with a floor of 0%) plus 175 basis points. The 2024 Term Loan was issued at 99.75% of par value. The proceeds from the 2024 Term Loan were used to retire the 2018 Term Loan and to pay related fees and expenses. Principal payments on the 2024 Term Loan will be made in quarterly installments on the last day of each March, June, September, and December in an amount equal to $5.75 million. The Company incurred financing fees of approximately $19.4 million in relation to this transaction, which are being amortized through the maturity date. During the year ended December 31, 2024, the Company repaid an aggregate of $17.3 million of principal on the 2024 Term Loan. As of December 31, 2024, the 2024 Term Loan had a principal balance of $2.3 billion. 2018 Term Loan The 2018 Term Loan consisted of a senior secured term loan with an initial aggregate principal amount of $2.4 billion that was set to mature on April 11, 2025. The 2018 Term Loan accrued interest, at SBA Senior Finance II’s election at either the Base Rate plus 75 basis points (with a zero Base Rate floor) or the Eurodollar Rate plus 175 basis points (with a zero Eurodollar Rate floor). On January 25, 2024, the Company, through its wholly owned subsidiary, SBA Senior Finance II, retired the 2018 Term Loan. In connection with the repayment, the Company expensed $3.3 million of net deferred financing fees and $1.2 million of original issuance discount related to the debt. Secured Tower Revenue Securities Tower Revenue Securities Terms As of December 31, 2024, the Company, through a New York common law trust (the “Trust”), had issued and outstanding an aggregate of $8.4 billion of Secured Tower Revenue Securities (“Tower Securities”). The sole asset of the Trust consists of a non-recourse mortgage loan made in favor of certain of the Company’s subsidiaries that are borrowers on the mortgage loan (the “Borrowers”) under which there is a loan tranche for each Tower Security outstanding with the same interest rate and maturity date as the corresponding Tower Security. The mortgage loan will be paid from the operating cash flows from the aggregate 9,516 tower sites owned by the Borrowers as of December 31, 2024. The mortgage loan is secured by (1) mortgages, deeds of trust, and deeds to secure debt on a substantial portion of the tower sites, (2) a security interest in the tower sites and substantially all of the Borrowers’ personal property and fixtures, (3) the Borrowers’ rights under certain tenant leases, and (4) all of the proceeds of the foregoing. For each calendar month, SBA Network Management, Inc., an indirect subsidiary (“Network Management”), is entitled to receive a management fee equal to 4.5% of the Borrowers’ operating revenues for the immediately preceding calendar month. The Borrowers may prepay any of the mortgage loan components, in whole or in part, with no prepayment consideration, (1) within six months (in the case of the component corresponding to the 2024-2C Tower Securities), within twelve months (in the case of the component corresponding to the 2019-1C Tower Securities, 2020-1C Tower Securities, 2021-1C Tower Securities, 2021-2C Tower Securities, and 2022-1C Tower Securities), eighteen months (in the case of the components corresponding to the 2020-2C Tower Securities and 2021-3C Tower Securities), or twenty-four months (in the case of the component corresponding to the 2024-1C Tower Security) of the anticipated repayment date of such mortgage loan component, (2) with proceeds received as a result of any condemnation or casualty of any tower owned by the Borrowers or (3) during an amortization period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable prepayment consideration. The prepayment consideration is determined based on the class of the Tower Securities to which the prepaid mortgage loan component corresponds and consists of an amount equal to the net present value associated with the portion of the principal balance being prepaid and calculated in accordance with the formula set forth in the mortgage loan agreement. To the extent that the mortgage loan components corresponding to the Tower Securities are not fully repaid by their respective anticipated repayment dates, the interest rate of each such component will increase by the greater of (1) 5% and (2) the amount, if any, by which the sum of (x) the 10 year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component. Pursuant to the terms of the Tower Securities, all rents and other sums due on any of the towers owned by the Borrowers are directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the indenture trustee after the release date are classified as short-term restricted cash on the Consolidated Balance Sheets (see Note 4). However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding twelve months, as of the end of any calendar quarter, falls to 1.30 x or lower, then all cash flow in excess of amounts required to make debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service Coverage Ratio exceeds 1.30 x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15 x as of the end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15 x for a calendar quarter. In addition, if any of the Tower Securities are not fully repaid by their respective anticipated repayment dates, the cash flow from the towers owned by the Borrowers will be trapped by the trustee for the Tower Securities and applied first to repay the interest, at the original interest rates, on the mortgage loan components underlying the Tower Securities, second to fund all reserve accounts and operating expenses associated with those towers, third to pay the management fees due to Network Management, fourth to repay principal of the Tower Securities and fifth to repay the additional interest discussed above. Furthermore, the advance rents reserve requirement states that the Borrowers are required to maintain an advance rents reserve at any time the monthly tenant Debt Service Coverage Ratio is equal to or less than 2:1 and for two calendar months after such coverage ratio again exceeds 2:1. The mortgage loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets.
