SBA COMMUNICATIONS CORP Income Taxes Disclosure

The provision for income taxes consists of the following components:

The tables below provide a reconciliation of the provision for income taxes at the statutory U.S. Federal tax rate (21%) and the effective income tax rate. The 2025 amounts in the reconciliation are presented under the new ASC 740 guidance effective for annual periods beginning after December 15, 2024. The Company has applied the guidance prospectively.

(1)States making up more than 50% of the state tax expense include Louisiana, Florida, Texas, and New Hampshire.

(2)This item includes the effect of foreign exchange rate changes which were previously shown on a separate line.

The table below provides cash paid for income taxes by jurisdiction representing more than 5% of the Company’s total cash paid for income taxes.

The components of the net noncurrent deferred income tax asset (liability) accounts are as follows:

(1)Of these amounts, $35,716 and $317,109 are included in Other assets and Other long-term liabilities, respectively, on the accompanying Consolidated Balance Sheets as of December 31, 2025. As of December 31, 2024, $53,974 and $85,172 are included in Other assets and Other long-term liabilities, respectively, on the accompanying Consolidated Balance Sheet.

A deferred tax asset is reduced by a valuation allowance if based on the weight of all available evidence, including both positive and negative evidence, it is more likely than not (a likelihood of more than 50%) that the value of such assets will not be realized. The valuation allowance should be sufficient to reduce the deferred tax asset to the amount that is more likely than not to be realized. The realization of deferred tax assets, including carryforwards and deductible temporary differences, depends upon the existence of sufficient taxable income of the same character during the carryback or carryforward period. All sources of taxable

income available to realize the deferred tax asset, including the future reversal of existing temporary differences, future taxable income exclusive of reversing temporary differences and carryforwards, taxable income in carryback years and tax-planning strategies, should be considered.

The Company has recorded a valuation allowance for certain deferred tax assets as management believes that it is not “more-likely-than-not” that the Company will generate sufficient taxable income in future periods to recognize the assets. Valuation allowances of $14.3 million and $19.3 million were being carried to offset net deferred income tax assets as of December 31, 2025 and 2024, respectively. The net change in the valuation allowance for the years ended December 31, 2025 and 2024 was a decrease of $5.1 million and an increase of $3.2 million, respectively.

The Company has available at December 31, 2025, a federal NOL carry-forward of approximately $366.2 million. $343.8 million of these NOL carry-forwards will expire between 2029 and 2037, and $22.4 million have an indefinite carry-forward. As of December 31, 2025, $343.8 million of the federal NOLs are attributes of the REIT. The Company may use these NOLs to offset its REIT taxable income, and thus any required distributions to shareholders may be reduced or eliminated until such time as the NOLs have been fully utilized. The Internal Revenue Code places limitations upon the future availability of NOLs based upon changes in the equity of the Company. If these occur, the ability of the Company to offset future income with existing NOLs may be limited. In addition, the Company has available at December 31, 2025, a foreign NOL carry-forward of $67.0 million and a net state operating tax loss carry-forward of approximately $221.5 million. These net operating tax loss carry-forwards began to expire in 2025.

The tax losses generated in tax years 2006 and forward remain subject to audit adjustment, and tax years 2018 and forward are open to examination by the major jurisdictions in which the Company operates.

The Company is subject to income tax and other taxes in the geographic areas where it holds assets or operates, and the Company periodically receives notifications of audits, assessments, or other actions by taxing authorities. In certain jurisdictions, taxing authorities may issue notices and assessments that may not be reflective of the actual tax liability for which the Company will ultimately be liable. In the process of responding to assessments of taxes that the Company believes are not reflective of the Company’s actual tax liability, the Company avails itself of both administrative and judicial remedies. The Company evaluates the circumstances of each notification or assessment based on the information available and, in those instances in which the Company does not anticipate a successful defense of positions taken in its tax filings, a liability is recorded in the appropriate amount based on the underlying assessment.

The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return if applicable. As of December 31, 2025, 2024, and 2023 the total amount of unrecognized tax benefits are $14.9 million, $13.9 million, and $14.2 million, respectively, all of which would impact the effective rate if recognized. The Company expects the unrecognized tax benefits to change over the next 12 months if the applicable statute of limitations expire and the impact could range from zero to $3.0 million. For the period ended December 31, 2025, the Company recorded penalties and interest expense related to unrecognized tax benefits of $0.4 million as interest expense.

A reconciliation of the beginning and ending amount of unrecognized tax benefits are as follows:

In connection with a current tax assessment in Brazil, the taxing authorities have issued income tax deficiencies related to purchase accounting adjustments for tax years 2017 through 2020. In addition, the taxing authorities have issued income tax deficiencies related to the deductibility of foreign exchange losses on the Company’s intercompany loan for the 2020 tax year. The Company disagrees with these assessments and is appealing with the higher appellate taxing authorities. The Company estimates that there is a more likely than not probability that the Company’s position will be sustained upon appeal. Accordingly, no liability has been recorded. The Company will continue to vigorously contest the adjustments and expect to exhaust all administrative and judicial remedies necessary to resolve the matters, which could be a lengthy process. There can be no assurance that these matters will be resolved in the Company’s favor, and an adverse outcome, or any future tax examinations involving similar assertions, could have a material effect on the Company’s results of operations or cash flows in any one period. As of December 31, 2025, the Company
