Item 7.     Management's Discussion and Analysis of Financial Condition and Results of Operations

General Overview

Overview

We own, operate and lease shared communications infrastructure. See "Item 1. Business" for a further discussion of our business, including our long-term strategy, our REIT status, certain key terms of our tenant contracts and growth trends in the demand for data.

On March 13, 2025, management signed the Strategic Fiber Agreement to sell our Fiber Business, with Zayo acquiring the fiber solutions business and EQT acquiring the small cell business. Under the Strategic Fiber Agreement, we will receive $8.5 billion in aggregate, subject to certain closing adjustments. The Strategic Fiber Transaction is expected to close in the first half of 2026, subject to certain closing conditions and regulatory approvals. See "Item 1. Business—Overview" for further discussion of the pending sale of the Fiber Business.

As the aforementioned sale represents a material strategic shift for the Company, the Fiber Business' results and net assets are presented herein as discontinued operations and comparable prior periods have been recast to reflect this change. Related to the classification of the Fiber Business as "held for sale", we have recognized a loss from disposal of discontinued operations of approximately $1.6 billion, inclusive of estimated transaction fees, for the year ended December 31, 2025.

Following the classification of the Fiber Business as discontinued operations, we have one reportable segment that constitutes consolidated results of our tower operations. See notes 3 and 15 to our consolidated financial statements for a discussion of discontinued operations and our operating segment. Unless otherwise noted, all activities and amounts reported in this document relate to continuing operations and exclude activities and amounts related to discontinued operations.

Highlights of Business Fundamentals and Results

•Site rental revenues represented 95% of our 2025 net revenues. The vast majority of our site rental revenues is of a recurring nature and has been contracted for in prior years.

•We operate as a REIT for U.S. federal income tax purposes (see "Item 1. Business—REIT Status" and notes 2 and 10 to our consolidated financial statements)

•Potential growth resulting from the increasing demand for data

◦We expect existing and potential new tenant demand for our towers will result from (1) new technologies, (2) increased usage of mobile entertainment, mobile internet, and machine-to-machine applications, (3) adoption of other emerging and embedded wireless devices (including smartphones, laptops, tablets, wearables and other devices), (4) increasing smartphone penetration, (5) wireless carrier focus on expanding both network quality and capacity, (6) the adoption of other bandwidth-intensive applications (such as cloud services, artificial intelligence and video communications), (7) the availability of additional spectrum and (8) increased government initiatives to support connectivity throughout the U.S.

◦We expect U.S. wireless carriers will continue to focus on improving network quality and expanding capacity (including through 5G initiatives). We believe our towers provide an efficient and cost-effective solution to our wireless tenants' growing infrastructure needs.

◦Tenant additions on our towers are achieved at a low incremental operating cost, delivering high incremental returns.

◦Substantially all of our towers can accommodate additional tenancy, either as currently constructed or with appropriate modifications.

•Returning cash flows provided by operations to stockholders in the form of dividends (see also "Item 1. Business—Strategy")

◦During 2025, we paid common stock dividends totaling approximately $2.1 billion.

•Investing capital efficiently to grow cash flows

◦We had discretionary capital expenditures of $149 million for the year ended December 31, 2025, predominately related to improvements to existing towers to support additional tenants and purchases of land underneath our towers.

◦We expect to continue to construct and acquire new towers that we expect will generate future cash flow growth and attractive long-term returns by adding tenants to those assets over time.

◦We expect to continue to acquire land interests relating to land under our towers.

•Site rental revenues under long-term tenant contracts

34

◦Our tenant contracts have initial terms generally between five to 15 years with contractual escalators and multiple renewal periods generally between five to 10 years each, exercisable at the option of the tenant.

◦As of December 31, 2025, our weighted-average remaining term was approximately six years, exclusive of renewals exercisable at the tenants' option, currently representing approximately $23.7 billion of expected future cash inflows, exclusive of amounts due under the Master Lease Agreement and underlying agreements with DISH. See "Item 7. MD&A—General Overview—Outlook Highlights" for further discussion.

•Majority of our revenues from large wireless carriers

◦For the year ended December 31, 2025, approximately 90% of our site rental revenues were derived from T-Mobile, AT&T and Verizon Wireless. See "Item 1A. Risk Factors" and note 15 to our consolidated financial statements for a further discussion of our largest customers.

◦During 2025, our site rental revenues decreased approximately $200 million as a result of non-renewals related to the network consolidation of T-Mobile and Sprint.

•Majority of land under our towers under long-term control

◦For the year ended December 31, 2025, approximately 90% of our towers Adjusted Site Rental Gross Margin and approximately 80% of our towers Adjusted Site Rental Gross Margin was derived from towers located on land that we own or control for greater than 10 and 20 years, respectively. The aforementioned percentages include towers located on land that is owned, including through fee interests and perpetual easements, which represented approximately 40% of our towers Adjusted Site Rental Gross Margin.

•Minimal sustaining capital expenditure requirements

◦For the year ended December 31, 2025, sustaining capital expenditures represented less than 1% of net revenues.

•Debt portfolio with long-dated maturities extended over multiple years, with the vast majority of such debt having a fixed rate (see note 8 to our consolidated financial statements and "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for a further discussion of our debt)

◦As of December 31, 2025, our outstanding debt had a weighted average interest rate of 3.9% and weighted average maturity of approximately six years (assuming anticipated repayment dates on certain debt).

◦As of December 31, 2025, 84% of our debt has fixed rate coupons.

◦Our debt service coverage and leverage ratios are within their respective financial maintenance covenants. See "Item 7. MD&A—Liquidity and Capital Resources—Debt Covenants" for a further discussion of our debt covenants.

•During 2025, we repaid in full certain of our debt (see note 8 to our consolidated financial statements and "Item 7. MD&A—Liquidity and Capital Resources—Financing Activities" for further discussion of our debt transactions)

•Significant cash flows from operations

◦Net cash provided by operating activities was $3.1 billion for the year ended December 31, 2025.

◦In addition to the positive impact of contractual escalators, we expect to grow our core business of providing access to our towers as a result of future anticipated additional demand.

•2023 and 2024 Restructuring Plans

◦There were no restructuring charges in 2025 relating to either the 2023 Restructuring Plan or the 2024 Restructuring Plan. See note 17 to our consolidated financial statements for further discussion of the 2023 Restructuring Plan and 2024 Restructuring Plan.

Common Stock Dividend

During the first quarter of the year ended 2025, we paid a common stock dividend of $1.565 per share and during each of the following three quarters, we paid a common stock dividend of $1.0625 per share, totaling approximately $2.1 billion. We have updated our capital allocation framework to focus more on free cash flow generation and financial flexibility, which primarily drove our decision to reduce our dividend in the second quarter of 2025. As we grow cash flows, we expect to increase our dividend per share. Whether dividends are to be declared and the amount and timing thereof remain subject to the discretion of our board of directors. See note 11 to our consolidated financial statements.

Outlook Highlights

The following are certain highlights of our outlook that impact our business fundamentals described above.

•In January 2026, we delivered a notice of default and termination to DISH relating to our Master Lease Agreement and underlying agreements with DISH as a result of DISH failing to make required payments and defaulting on its obligations under the agreements. As a result of the termination, we assert in the notice that DISH owes us all remaining payments under the agreements, which total in excess of $3.5 billion. Our 2026 Outlook does not include any revenues from DISH.

35

•We expect a year over year reduction in site rental revenues related to (1) approximately $220 million from the aforementioned DISH termination, and (2) a decline in long-term deferred revenue amortization.

•In February 2026, we initiated a restructuring plan ("2026 Restructuring Plan") as part of our efforts to enhance the efficiency and effectiveness of our tower business.

◦We expect to realize approximately $65 million annualized run-rate savings in operating costs, of which approximately $55 million will be realized in 2026 due to timing. The remaining savings of approximately $10 million will be realized in 2027. We expect to incur aggregate restructuring charges of approximately $30 million in 2026 as a result of the 2026 Restructuring Plan, most of which we expect to incur in the first and second quarters of 2026. See "Item 1A. Risk Factors" for a discussion of risks related to our restructuring activities.

•Following the closure of the Strategic Fiber Transaction, which is expected to occur in the first half of 2026, we expect to use the proceeds from the sale to repurchase approximately $1 billion of shares and approximately $7 billion of debt.

◦As a result of the expected $7 billion repayment of debt, our 2026 interest expense is expected to decrease.

•Notwithstanding the plan to sell our Fiber Business, we expect to continue to invest a significant amount of our available capital in the form of discretionary capital expenditures in the Fiber Business until the closing of the Strategic Fiber Transaction.

Results of Operations

The following discussion of our results of operations for 2025 compared to 2024 should be read in conjunction with "Item 1. Business," "Item 7. MD&A—Liquidity and Capital Resources" and our consolidated financial statements. For a discussion of our results of operations and financial condition for 2024 compared to 2023 that is not included in this 2025 Form 10-K, see "Part II, Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on March 14, 2025.

The following discussion of our results of operations is based on our consolidated financial statements prepared in accordance with GAAP, which requires us to make estimates and judgments that affect the reported amounts (see "Item 7. MD&A—Accounting and Reporting Matters—Critical Accounting Policies and Estimates" and note 2 to our consolidated financial statements). See "Item 7. MD&A—Accounting and Reporting Matters—Non-GAAP Financial Measures" for a discussion of our use of (1) Adjusted Site Rental Gross Margin and (2) Adjusted Services and Other Gross Margin, including their respective definitions and (3) Adjusted EBITDA, including its definition and a reconciliation to net income (loss).

2025 and 2024

Total site rental revenues for 2025 decreased by $219 million, or 5%, from 2024. This decrease was predominately comprised of the factors depicted in the chart below:

(In millions of dollars; components may not sum to totals due to rounding)

(a)Represents site rental revenues growth from tenant additions across our entire portfolio and renewals or extensions of tenant contracts, exclusive of the impacts from both straight-line accounting and amortization of prepaid rent in accordance with GAAP.

(b)Includes $204 million of non-renewals associated with the T-Mobile and Sprint network consolidation.

Site rental revenues and Adjusted Site Rental Gross Margin for 2025 were $4.0 billion and $3.1 billion, respectively, compared to $4.3 billion and $3.3 billion, respectively, for 2024. The decrease of $219 million and $231 million in site rental revenue and Adjusted Site Rental Gross Margin, respectively, was primarily due to higher non-renewals of $204 million as a result of the T-Mobile and Sprint network consolidation, as well as a decrease in prepaid rent amortization of $61 million, as new leasing activity and contractual cash escalators were substantially offset by a decline in the associated straight-line accounting adjustment.

Adjusted Services and Other Gross Margin was $107 million for 2025 and increased by $16 million from $91 million from 2024, which is a reflection of the volume and mix of services and other offerings. Our services and other offerings are of a variable nature as these revenues are not under long-term tenant contracts.

Selling, general and administrative expenses for 2025 were $383 million and decreased by $52 million, or 12%, from $435 million from 2024. The decrease in selling, general and administrative expenses was related to a decrease in legal and consulting expense, primarily related to our recent proxy contest in 2024, and a decrease in employee- and facility-related costs as a result of our aforementioned restructuring activities of the 2023 and 2024 Restructuring Plans.

Depreciation, amortization and accretion was approximately $690 million for 2025 and decreased by $46 million, or 6%, from 2024. This decrease predominately resulted from certain fixed assets and site rental contracts and tenant relationships intangible assets becoming fully depreciated or amortized, respectively.

There were no restructuring charges recorded in connection with the 2023 and 2024 Restructuring Plans during 2025 compared to $70 million recorded during 2024. The actions associated with the 2023 and 2024 Restructuring Plans were substantially completed and the related charges were recorded by December 31, 2024. See note 17 to our consolidated financial statements for further discussion of our 2023 and 2024 Restructuring Plans.

Interest expense and amortization of deferred financing costs, net was $972 million for 2025 and increased by $40 million, or 4%, from $932 million during 2024. The increase predominately resulted from an increase in our outstanding

38

indebtedness due to the financing of our discretionary capital expenditures, including those presented within discontinued operations. See note 8 to our consolidated financial statements, "Item 1A. Risk Factors" and "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for a further discussion of our debt and interest rate exposure.

The provision for income taxes for 2025 and 2024 were $16 million and $18 million, respectively. For both 2025 and 2024, the effective tax rate differs from the federal statutory rate predominately due to our REIT status, including the dividends paid deduction. See "Item 1. Business—REIT Status," "Item 7. MD&A—Accounting and Reporting Matters—Critical Accounting Policies and Estimates" and note 10 to our consolidated financial statements.

Income (loss) from continuing operations was $1.1 billion during 2025 compared to $1.2 billion during 2024. The decrease was related to the previously-mentioned decreases in site rental revenues, the previously-mentioned increases in interest expense and amortization of deferred financing costs, net, while being partially offset by a decrease in restructuring charges, depreciation, amortization and accretion expense and selling, general, and administrative expenses.

Income (loss) from discontinuing operations before gain (loss) from disposal, net of tax, was $916 million during 2025 compared to $(5,065) million during 2024. The increase was primarily driven by the absence of a $106 million asset write-down charge and $5.0 billion goodwill impairment charge, both of which occurred in 2024. In addition, there was a decrease in depreciation, amortization and accretion related to the ceasing of depreciation and amortization of the Fiber Business long-lived assets classified as "held for sale."

Gain (loss) from disposal of discontinued operations was $(1.6) billion during 2025. The loss was primarily related to the classification during the first quarter of 2025 of the Fiber Business as "held for sale" and the additional investment in the Fiber Business during the remainder of 2025. The loss represents the excess of the carrying value of the Fiber Business over the purchase price, less estimated costs to sell.

Net income (loss) was $444 million during 2025 compared to $(3,903) million during 2024. The increase was primarily due to the change in income (loss) from discontinued operations, net of tax of $4.4 billion, primarily due to the absence of the previously mentioned $5.0 billion goodwill impairment charge recorded in 2024.

Adjusted EBITDA decreased by $172 million, or 6%, from 2024 to 2025, reflecting the previously mentioned decreases in site rental revenue, partially offset by previously mentioned decreases in selling, general, and administrative expenses and increase in Adjusted Services and Other Gross Margin.

Liquidity and Capital Resources

Overview

General. Our core business generates revenues under long-term tenant contracts (see "Item 1. Business—Overview" and "Item 7. MD&A—General Overview—Overview") from the largest U.S. wireless carriers and other towers tenants. As a leading provider of towers in the U.S., our strategy is to create long-term stockholder value via a combination of (1) growing cash flows generated from our existing towers, (2) returning a meaningful portion of our cash generated by operating activities to our stockholders in the form of dividends and share repurchases, and (3) investing capital efficiently to grow cash flows. Our strategy is based, in part, on our belief that the U.S. is the most attractive market for towers investment with the greatest long-term growth potential. We measure our efforts to create "long-term stockholder value" by the growth in our per share results. See "Item 1. Business—Strategy" for a further discussion of our strategy.

We have engaged, and expect to continue to engage, in discretionary investments that we believe will maximize long-term stockholder value. These investments include the acquisition of land interests, making improvements, structural enhancements to our existing towers, and constructing and acquiring new towers that we expect will generate future cash flow growth and attractive long-term returns by adding tenants to those assets over time. We have recently spent, and expect to continue to spend, a significant percentage of our discretionary investments on the construction of small cells and fiber until the closing of the sale of the Fiber Business. See note 3 to our consolidated financial statements and "Item 7. MD&A—General Overview" for further discussion of the pending sale of the Fiber Business. We seek to fund our discretionary investments with both cash generated by operating activities and cash available from financing capacity, such as the use of our availability under our 2016 Revolver, issuances under our CP Program, debt financings and issuances of equity or equity-related securities, including under our 2024 ATM Program or any similar successor program.

We seek to maintain a capital structure that we believe drives long-term stockholder value and optimizes our weighted-average cost of capital. Additionally, we expect to maintain an investment grade credit profile. As of December 31, 2025, our contractual debt maturities over the next 12 months consist of (1) Commercial Paper Notes, of which we had $1.9 billion outstanding as of February 19, 2026, (2) the 4.450%, 3.700%, and 1.050% senior unsecured notes due February, June and July 2026, respectively ("4.450% Senior Notes", "3.700% Senior Notes", and "1.050% Senior Notes") and (3) principal payments on certain outstanding debt. Amounts available under our CP Program may be repaid and re-issued from time to time and we intend to maintain available commitments under our 2016 Revolver in an amount at least equal to the amount of Commercial Paper Notes outstanding.

We operate as a REIT for U.S. federal income tax purposes. We expect to continue to pay minimal cash income taxes as a result of our REIT status and our NOLs. See "Item 1. Business—REIT Status," "Item 7. MD&A—General Overview" and note 10 to our consolidated financial statements.

Liquidity Position. The following is a summary of our capitalization and liquidity position as of December 31, 2025. See "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" and note 8 to our consolidated financial statements for additional information regarding our debt as well as note 11 to our consolidated financial statements for additional information regarding our 2024 ATM Program.

At any point in time, we intend to maintain available commitments under our 2016 Revolver in an amount at least equal to the amount of outstanding Commercial Paper Notes. See note 8 to our consolidated financial statements.

As of December 31, 2025, over the next 12 months:

•Following the closure of the Strategic Fiber Transaction, which is expected to occur in the first half of 2026, we expect to use the proceeds from the sale to repurchase approximately $1 billion of shares and repay approximately $7 billion of debt. Future share repurchases are subject to the discretion and approval of our board of directors.

◦Upon closure, we do not expect that the absence of cash flows from the Fiber Business will have an adverse impact on our liquidity position. While the Fiber Business generated cash inflows from operating activities, such cash inflows were generally offset by cash used for investing activities due to significant discretionary capital expenditures. As a result, the Fiber Business did not historically provide net liquidity to our Company.

40

•In addition to the aforementioned proceeds from the sale, our liquidity sources may include (1) cash on hand, (2) cash generated by our operating activities, (3) availability under our 2016 Revolver, (4) issuances under our CP Program, and (5) issuances of equity pursuant to our 2024 ATM Program or any similar successor program. Our liquidity uses are expected to include (1) maturing debt obligations of $4.7 billion (consisting of Commercial Paper Notes, the 4.450% Senior Notes, the 3.700% Senior Notes, the 1.050% Senior Notes and principal payments on certain outstanding debt), (2) additional debt paydowns using the proceeds from the sale discussed above, (3) share repurchases as discussed above, (4) common stock dividend payments, subject to declaration by our board of directors (see "Item 7. MD&A—General Overview—Common Stock Dividend"), and (5) capital expenditures.

•Amounts available under our CP Program may be repaid and re-issued from time to time and we intend to maintain available commitments under our 2016 Revolver in an amount at least equal to the amount of Commercial Paper Notes outstanding. Historically, from time to time, we have accessed the capital markets to issue debt and equity.

•See "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for a discussion of interest rate risk and note 8 to our consolidated financial statements for a tabular presentation of our debt maturities and a discussion of anticipated repayment dates.

Operating Activities

The increase in net cash provided by operating activities of $114 million from 2024 to 2025 was driven by a $52 million increase in net cash provided by continuing operations and $62 million increase in net cash provided by discontinued operations. The $52 million increase in net cash provided by continuing operations is due primarily to a net increase from changes in working capital partially offset by the aforementioned decrease in Adjusted Site Rental Gross Margin. Changes in working capital contribute to variability in net cash provided by operating activities, largely due to the timing of advanced payments by us and advanced receipts from tenants. We expect to grow our net cash provided by operating activities in the future (exclusive of changes in working capital) if we realize expected growth in our core business.

The increase of $62 million in net cash provided by discontinued operations is due primarily to increased operating profit of our Fiber Business and a net increase from changes in working capital.

Investing Activities

Net cash used for investing activities for 2025 decreased by $62 million from 2024, driven by a $3 million increase in net cash used for investing by continuing operations and $65 million decrease in net cash used for discontinuing operations.

Our capital expenditures are categorized as discretionary or sustaining as described below.

•Discretionary capital expenditures relating to continuing operations are those made with respect to activities which we believe exhibit sufficient potential to enhance long-term stockholder value. Discretionary capital expenditures, including with respect to discontinued operations, primarily consist of expansion or development of our communications infrastructure (including capital expenditures related to (1) enhancing communications infrastructure in order to add new tenants for the first time or support subsequent tenant equipment augmentations or (2) modifying the structure of a communications infrastructure asset to accommodate additional tenants) and construction of new communications infrastructure. Discretionary capital expenditures also include purchases of land interests (which primarily relate to land assets under towers as we seek to manage our interests in the land beneath our towers), certain technology-related investments necessary to support and scale future customer demand for our communications infrastructure, and other capital projects. The expansion or development of existing communications infrastructure to accommodate new leasing typically varies based on, among other factors: (1) the type of communications infrastructure, (2) the scope, volume, and mix of work performed on the communications infrastructure, (3) existing capacity prior to installation, or (4) changes in structural engineering regulations and standards. Currently, construction of new communications infrastructure is predominately comprised of the construction of small cells and fiber (including certain construction projects that may take 18 to 36 months to complete). Our decisions regarding

41

discretionary capital expenditures are influenced by the availability and cost of capital and expected returns on alternative uses of cash, such as payments of dividends and investments.

•Sustaining capital expenditures consist of those capital expenditures (including with respect to discontinued operations) not otherwise categorized as discretionary capital expenditures, such as (1) maintenance capital expenditures on our communications infrastructure assets that enable our tenants' ongoing quiet enjoyment of the communications infrastructure and (2) ordinary corporate capital expenditures.

A summary of our capital expenditures for continuing operations for the last three years is as follows:

(a)Includes $7 million, $12 million and $32 million of capital expenditures incurred during the years ended December 31, 2025, 2024 and 2023, respectively, in connection with tenant installations and upgrades on our towers.

The $65 million reduction in discretionary capital expenditures for our discontinued operations during 2025 compared to the same period in 2024 was primarily related to the higher return thresholds on new growth opportunities as a result of the review of the Fiber Business completed in the second quarter of 2024. The discretionary capital expenditures for our continuing operations were relatively stable as tower investments related to tenant activity were offset by an increase in land purchases under our towers.

Financing Activities

We seek to allocate cash generated by our operations in a manner that will enhance long-term stockholder value, which may include various financing activities such as (in no particular order): (1) paying dividends on our common stock, subject to declaration by our board of directors, (2) purchasing our common stock or (3) purchasing, repaying, or redeeming our debt. See "Item 7. MD&A—General Overview—Common Stock Dividend," "Item 7. MD&A—Liquidity and Capital Resources—Overview" and notes 8 and 11 to our consolidated financial statements.

In 2025, our financing activities predominately related to the following:

•paying an aggregate of $2.1 billion in dividends on our common stock;

•repaying in full the previously outstanding Tower Revenue Notes, Series 2015-2 on the anticipated repayment date in May 2025;

•repaying in full the previously outstanding 1.350% senior unsecured notes on the contractual maturity date in July 2025; and

•net borrowings under our revolving credit facility and net issuances under our commercial paper program, which collectively were used for general corporate purposes.

In 2024, our financing activities predominately related to the following:

•paying an aggregate of $2.7 billion in dividends on our common stock;

•repaying in full the previously outstanding 3.200% senior unsecured notes on the contractual maturity date in September 2024; and

•issuing $550 million aggregate principal amount of 4.900% senior unsecured notes and $700 million aggregate principal amount of 5.200% senior unsecured notes in August 2024, the net proceeds of which were used to repay a portion of the outstanding indebtedness under our CP Program and pay related fees and expenses.

Incurrence, Purchases and Repayments of Debt. See note 8 to our consolidated financial statements, "Item 7. MD&A—General Overview" and "Item 7. MD&A—Liquidity and Capital Resources—Overview—Liquidity Position" for further discussion of our recent issuances, purchases, redemptions and repayments of debt.

Common Stock. See note 11 to our consolidated financial statements for further information regarding our common stock as well as dividends declared and paid.

ATM Program. We previously maintained a 2021 ATM Program through which we had the right to issue and sell shares of our common stock having an aggregate gross sales price of up to $750 million to or through sales agents. In March 2024, we terminated the formerly outstanding 2021 ATM Program with the entire gross sales price of $750 million remaining unsold.

In March 2024, we established the 2024 ATM Program through which we may issue and sell shares of our common stock having an aggregate gross sales price of up to $750 million. Sales under the 2024 ATM Program, or any similar successor program, may be made by means of ordinary brokers' transactions on the New York Stock Exchange ("NYSE") or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or, subject to our specific instructions, at negotiated prices. We intend to use the net proceeds from any sales under the 2024 ATM Program, or any similar successor program, for general corporate purposes, which may include (1) the funding of future acquisitions or investments or (2) the repayment or repurchase of any outstanding indebtedness. We have not sold any shares of common stock under the 2024 ATM Program. See also note 11 to our consolidated financial statements. As of February 19, 2026, we had $750 million of gross sales of common stock availability remaining on our 2024 ATM Program.

Credit Facility. See note 8 to our consolidated financial statements for further information regarding our 2016 Credit Facility. As of February 19, 2026, we had an outstanding balance under our 2016 Revolver of $1.8 billion and maintained $5.2 billion in undrawn availability. The proceeds from our 2016 Revolver may be used for general corporate purposes, which may include the financing of capital expenditures, acquisitions, the repayment or repurchase of any outstanding indebtedness and purchases of our common stock.

Commercial Paper Program. See note 8 to our consolidated financial statements for further information regarding our CP Program. As of February 19, 2026, there was $1.9 billion outstanding under our CP Program. The proceeds from our Commercial Paper Notes may be used for general corporate purposes, which may include the financing of capital expenditures, acquisitions, the repayment or repurchase of any outstanding indebtedness and purchases of our common stock.

Restricted Cash and Cash Equivalents. Pursuant to the indentures governing certain of our operating companies' debt securities, all rental cash receipts of the issuers of these debt instruments and their subsidiaries are restricted and held by an indenture trustee. The restricted cash and cash equivalents in excess of required reserve balances is subsequently released to us in accordance with the terms of the indentures. See also note 2 to our consolidated financial statements.

Material Cash Requirements

The following table summarizes our material cash requirements as of December 31, 2025. These material cash requirements relate primarily to our outstanding borrowings or lease obligations for land interests under our towers. The debt maturities reflect contractual maturity dates and do not consider the impact of the principal payments that will commence following the anticipated repayment dates of certain debt (see footnote (b)). The debt and interest payments on debt below do not consider the aforementioned expected use of proceeds from the closure of the Strategic Fiber Transaction.

(a)The impact of principal payments that will commence following the anticipated repayment date of our Tower Revenue Notes, Series 2018-2 is not considered. The Tower Revenue Notes, Series 2018-2 has a principal amount of $750 million, with an anticipated repayment date in 2028. See note 8 to our consolidated financial statements for our definition of and additional information regarding the 2018 Tower Revenue Notes.

(b)If the Tower Revenue Notes, Series 2018-2 are not repaid in full by the anticipated repayment date, the interest rate increases by approximately 5% per annum and monthly principal payments commence using the Excess Cash Flow (as defined in the indenture governing the Tower Revenue Notes, Series 2018-2) of the issuers of the Tower Revenue Notes, Series 2018-2. The Tower Revenue Notes, Series 2018-2 are presented based on their contractual maturity date in 2048 and include the impact of an assumed 5% increase in interest rate that would occur following the anticipated repayment date but exclude the impact of monthly principal payments that would commence using Excess Cash Flow of the issuers of the Tower Revenue Notes, Series 2018-2. The full year 2025 Excess Cash Flow of the issuers of the Tower Revenue Notes, Series 2018-2 was approximately $1.0 billion. We currently expect to refinance or repay these notes on or prior to the anticipated repayment date.

(c)Includes the unused commitment fees on our 2016 Credit Facility. Interest payments on the variable rate debt are based on estimated rates currently in effect. See note 8 to our consolidated financial statements for information regarding potential upward or downward adjustments to the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility if we achieve specified annual sustainability targets or fail to meet annual sustainability thresholds. Each annual period presented assumes the downward adjustments in the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility. See "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for a discussion of our interest rate risk.

(d)Amounts relate primarily to lease obligations for the land on which our towers are located and are based on the assumption that payments will be made for certain renewal periods exercisable at our option that are reasonably certain to be exercised and excludes our contingent payments for operating leases (such as payments based on revenues derived from the tower located on the leased asset) as such arrangements are excluded from our operating lease liability. See note 14 to our consolidated financial statements for further discussion of our operating lease obligations. See also the table below summarizing remaining terms to expiration.

The following chart summarizes our rights to the land interests under our towers, including renewal terms exercisable at our option, as of December 31, 2025. As of December 31, 2025, the leases for land interests under our towers had an average remaining life of approximately 35 years, weighted based on towers Adjusted Site Rental Gross Margin. See "Item 1A. Risk Factors" for a discussion of retaining the rights to land under our towers.

(a)Inclusive of land owned through fee interests and perpetual easements.

(b)For the three months ended December 31, 2025, without consideration of the term of the tenant contract.

Debt Covenants

Our 2016 Credit Agreement contains financial maintenance covenants. We are currently in compliance with these financial maintenance covenants and, based upon our current expectations, we believe we will continue to comply with our financial maintenance covenants. In addition, certain of our debt agreements contain restrictive covenants that place restrictions on us and may limit our ability to, among other things, incur additional debt and liens, purchase our securities, make capital expenditures, dispose of assets, undertake transactions with affiliates, make other investments, pay dividends or distribute excess cash flow. See note 8 to our consolidated financial statements for further discussion of our debt covenants. See also "Item 1A. Risk Factors" for a discussion of compliance with our debt covenants. The following are ratios applicable to the financial maintenance covenants under the 2016 Credit Agreement as of December 31, 2025.

Accounting and Reporting Matters

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are those that we believe (1) are most important to the portrayal of our financial condition and results of operations or (2) require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. In many cases, the accounting treatment of a particular transaction is specifically prescribed by GAAP. In other cases, management is required to exercise judgment in the application of accounting principles with respect to particular transactions. Accordingly, actual results could differ materially from our estimates. The critical accounting policies and estimates for 2025 are not intended to be a comprehensive list of our accounting policies and estimates. See note 2 to our consolidated financial statements for a summary of our significant accounting policies.

Lease Accounting—Lessee. Our lessee arrangements primarily consist of ground leases for land under our towers and are for an initial term generally between five to 15 years. We also enter into ground leases, such as term easements, in which we prepay the entire term. The majority of our lease agreements have certain termination rights that provide for cancellation after a notice period and multiple renewal options exercisable at our option. We include certain renewal option periods in the lease term when we determine that the options are reasonably certain to be exercised.

Operating lease expense is recognized on a ratable basis, regardless of whether the payment terms require us to make payments annually, semi-annually, quarterly, monthly, or for the entire term in advance. Certain of our ground lease agreements contain fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the change in consumer price index ("CPI")). If the payment terms include fixed escalators, upfront payments, or rent-free periods, the effect of such increases is recognized on a straight-line basis. When calculating straight-line ground lease expense, we consider all fixed elements of contractual escalation provisions, even if such escalation provisions contain a variable element in addition to a minimum. We calculate the straight-line expense over the contract's estimated lease term, including any renewal option periods that we deem reasonably certain to be exercised.

We recognize a right-of-use ("ROU") asset (and, as applicable, a corresponding lease liability) for each of our operating leases. ROU assets represent our right to use an underlying asset for the estimated lease term, and lease liabilities represent the present value of our future lease payments. In assessing our leases and determining our lease liability at lease commencement or upon modification, we are not able to readily determine the rate implicit for our lessee arrangements and thus use our incremental borrowing rate on a collateralized basis to determine the present value of our lease payments. Our ROU assets are measured as the balance of the lease liability plus any prepaid or accrued lease payments and any unamortized initial direct costs.

We review the carrying value of our ROU assets for impairment, similar to our other long-lived assets, whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. We could record impairments in the future if there are changes in (1) long-term market conditions, (2) expected future operating results or (3) the utility of the assets that negatively impact the fair value of our ROU assets.

Revenue Recognition. 95% of our total revenue for 2025 consisted of site rental revenues, which are recognized on a ratable basis over the fixed, non-cancelable term of the relevant tenant contract, generally between five to 15 years, regardless of whether the payments from the tenant are received in equal monthly amounts during the life of a tenant contract. Certain of our tenant contracts contain (1) fixed escalation clauses (such as fixed-dollar or fixed-percentage increases) or inflation-based escalation clauses (such as those tied to the change in CPI), (2) multiple renewal periods exercisable at the tenant's option and (3) only limited termination rights at the applicable tenant's option through the current term. If the payment terms call for fixed escalators, upfront payments, or rent-free periods, the revenue is recognized on a straight-line basis over the fixed, non-cancelable term of the tenant contract. When calculating our straight-line rental revenues, we consider all fixed elements of tenant contractual escalation provisions, even if such escalation provisions contain a variable element (such as an escalator tied to an inflation-based index) in addition to a minimum. Since we recognize revenue on a straight-line basis, a portion of the site rental revenues in a given period represents cash collected or contractually collectible in other periods. Our assets related to straight-line site rental revenues are recorded within "Current portion of deferred site rental receivables" and "Deferred site rental receivables" on the consolidated balance sheet. Amounts billed or received prior to being earned are deferred and reflected in "Deferred revenues" and "Other long-term liabilities" on the consolidated balance sheet. Amounts to which we have an unconditional right to payment, which are related to both satisfied or partially satisfied performance obligations, are recorded within "Receivables, net" on the consolidated balance sheet.

As part of our effort to provide comprehensive tower solutions, as an ancillary business, we also offer certain services, which represented 5% of our total revenues for 2025. For the periods presented, such services and other revenues consisted predominately of (1) site development services relating to existing or new tenant equipment installations, including: site

46

acquisition, architectural and engineering, or zoning and permitting (collectively, "site development services") and (2) installation services. See note 17 to our consolidated financial statements for a discussion of the 2023 Restructuring Plan, which included discontinuing installation services as a towers product offering. Our services generally have a duration of one year or less. Upon contract commencement, we assess our services to tenants and identify performance obligations for each promise to provide a distinct service.

We may have multiple performance obligations for site development services, which primarily include: structural analysis, zoning, permitting and construction drawings. For each of the above performance obligations, services revenues are recognized at completion of the applicable performance obligation, which represents the point at which we believe we have transferred goods or services to the tenant. The revenue recognized is based on an allocation of the transaction price among the performance obligations in a respective contract based on estimated standalone selling price.

The transaction price for tower installation services consists of amounts for (1) permanent improvements to our towers that represent a lease component and (2) the performance of the service. Amounts under our tower installation services agreements that represent a lease component are recognized as site rental revenues on a ratable basis over the length of the associated estimated lease term. For the performance of the tower installation service, we have one performance obligation, which is satisfied at the time of the applicable installation or augmentation and recognized as services and other revenues.

Since performance obligations are typically satisfied prior to receiving payment from tenants, the unconditional right to payment is recorded within "Receivables, net" on our consolidated balance sheet.

Accounting for Long-Lived Assets—Useful Lives. We are required to make subjective assessments as to the useful lives of our tangible and intangible assets for purposes of determining depreciation, amortization and accretion expense that, if incorrectly estimated, could be material to our consolidated financial statements. Depreciation expense for our property and equipment is computed using the straight-line method over the estimated useful lives of our various classes of tangible assets. A substantial portion of our property and equipment represents the cost of our towers, the majority of which is depreciated with an estimated useful life equal to the shorter of 20 years or the term of the underlying ground lease (where applicable and including optional renewals).

The useful lives of our intangible assets are estimated based on the period over which the intangible asset is expected to benefit us and gives consideration to the expected useful life of other assets to which the useful life may relate. We review the expected useful lives of our intangible assets on an ongoing basis and adjust if necessary. Amortization expense for intangible assets is computed using the straight-line method over the estimated useful life of each of the intangible assets. The useful lives of site rental contracts and tenant relationships intangible assets are limited by the maximum depreciable life of the tower (20 years), as a result of the interdependency of the tower and the site rental contracts and tenant relationships. In contrast, the site rental contracts and tenant relationships are estimated to provide economic benefits for several decades because of the low rate of tenant cancellations and high rate of tenant retention experienced to date. Thus, while site rental contracts and tenant relationships intangible assets are valued based upon the fair value of the site rental contracts and tenant relationships which includes assumptions regarding both (1) tenants' exercise of optional renewals contained in the acquired leases and (2) renewals of the acquired leases past the contractual term including exercisable options, site rental contracts and tenant relationships intangible assets are amortized over a period not to exceed 20 years as a result of the useful life being limited by the depreciable life of the tower.

Accounting for Long-Lived Assets—Impairment Evaluation. We review the carrying values of property and equipment, intangible assets, or other long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable.

We utilize the following dual grouping policy for purposes of determining the unit of account for testing impairment of site rental contracts and tenant relationships intangible assets:

(1)we pool site rental contracts and tenant relationships intangible assets and property and equipment into portfolio groups; and

(2)we separately pool the site rental contracts and tenant relationships by significant tenant or by tenant grouping for individually insignificant tenants, as appropriate.

We first pool site rental contracts and tenant relationships intangible assets and property and equipment into portfolio groups for purposes of determining the unit of account for impairment testing, because we view towers as portfolios and towers in a given portfolio and its related tenant contracts are not largely independent of the other towers in the portfolio. We re-evaluate the appropriateness of the pooled groups at least annually. This use of grouping is based in part on (1) our limitations regarding disposal of towers, (2) the interdependencies of tower portfolios, and (3) the manner in which towers are traded in the marketplace. The vast majority of our site rental contracts and tenant relationships intangible assets and property and equipment

47

are pooled into the U.S. owned tower group. Secondly, and separately, we pool the site rental contracts and tenant relationships by significant tenant or by tenant grouping for individually insignificant tenants, as appropriate, for purposes of determining the unit of account for impairment testing because we associate the value ascribed to site rental contracts and tenant relationships intangible assets to the underlying contracts and related tenant relationships acquired.

Our determination that an adverse event or change in circumstance has occurred that indicates that the carrying amounts may not be recoverable will generally involve (1) a deterioration in an asset's financial performance compared to historical results, (2) a shortfall in an asset's financial performance compared to forecasted results, or (3) changes affecting the utility and estimated future demands for the asset. When considering the utility of our assets, we consider events that would meaningfully impact (1) our towers or (2) our tenant relationships. For example, consideration would be given to events that impact (1) the structural integrity and longevity of our towers or (2) our ability to derive benefit from our existing tenant relationships, including events such as tenant's bankruptcy or insolvency or loss of a significant tenant.

If the sum of the associated estimated future cash flows (undiscounted) from an asset group is less than its carrying amount, an impairment loss may be recognized. If the carrying value were to exceed the undiscounted cash flows, measurement of an impairment loss would be based on the fair value of the asset, which is based on an estimate of discounted future cash flows. The most important estimates for such calculations of undiscounted cash flows are (1) the expected additions of new tenants and equipment on our towers and (2) estimates regarding tenant cancellations and renewals of tenant contracts. We could record impairments in the future if changes in long-term market conditions, expected future operating results or the utility of the assets results in changes for our impairment test calculations which negatively impact the fair value of our property and equipment and intangible assets, or if we changed our unit of account in the future.

There were no events or circumstances that caused us to review the carrying value of our intangible assets or property and equipment due in part to our assets performing consistently with or better than our expectations.

Approximately 5% of our total towers currently have no tenants. We continue to pay operating expenses on these towers in anticipation of obtaining tenants on these towers in the future, primarily because of the demographics and continuing increase in demand for data in the areas around these individual towers. To the extent we do not believe there are long-term prospects of obtaining tenants on an individual asset and all other possible avenues for recovering the carrying value have been exhausted, including sale of the asset, we appropriately reduce the carrying value of such assets to fair value.

Accounting for Goodwill—Impairment Evaluation. Management tests goodwill for impairment at least annually or whenever events or circumstances indicate the carrying amount may not be recoverable. The annual test begins with goodwill and all intangible assets being allocated to our single reporting unit which is the same as our single operating segment. We then perform a qualitative assessment to determine whether it is "more likely than not" that the fair value of the reporting unit is less than its carrying amount. If we conclude that it is "more likely than not" that the fair value of a reporting unit is less than its carrying amount, we would be required to perform a quantitative goodwill impairment test. The quantitative goodwill impairment test compares the estimated fair value of the reporting unit and the carrying value of the reporting unit. If the carrying amount of a reporting unit is greater than its fair value, an impairment loss shall be recognized in an amount equal to such excess, limited to the total amount of goodwill allocated to the reporting unit. See note 6 to our consolidated financial statements. We performed our most recent annual goodwill impairment test as of October 1, 2025, which resulted in no impairment.

Deferred Income Taxes. We operate as a REIT for U.S. federal income tax purposes. Our REIT taxable income is generally not subject to federal and state income taxes as a result of the deduction for dividends paid and any usage of our remaining NOLs. Accordingly, the only provision or benefit for federal income taxes for the year ended December 31, 2025 relates to TRSs. Furthermore, as a result of the deduction for dividends paid, some or all of our NOLs related to our REIT may expire without utilization. See "Item 1. Business—REIT Status" for a discussion of the impact of our REIT status. 

Our TRSs will continue to be subject, as applicable, to federal and state income taxes and foreign taxes in the jurisdictions in which such assets and operations are located. Our foreign assets and operations (including our tower operations in Puerto Rico) are subject to foreign income taxes in the jurisdictions in which such assets and operations are located, regardless of whether they are included in a TRS or not. Our ability to utilize our NOLs is dependent, in part, upon us having sufficient future earnings to utilize our NOLs before they expire. Our federal and state NOLs are valued at a tax rate of 0% for deferred income tax purposes due to our REIT status. Additionally, our foreign NOLs are offset by a valuation allowance. As such, a change to market conditions that impacts our ability to generate sufficient future taxable income to utilize our NOLs would not require us to record an additional valuation allowance. For a further discussion of our benefit (provision) for income taxes, see "Item 7. MD&A—Results of Operations" and note 10 to our consolidated financial statements.

Non-GAAP Financial Measures

In addition to the financial results we present that have been prepared in accordance with generally accepted accounting principles ("GAAP"), we also provide information about three non-GAAP financial measures: Adjusted Site Rental Gross Margin, Adjusted Services and Other Gross Margin and Adjusted EBITDA..

We define Adjusted Site Rental Gross Margin as net income (loss) plus services and other costs of operations, selling, general and administrative expenses, restructuring charges (credits), asset write-down charges, goodwill impairment, acquisition and integration costs, depreciation, amortization and accretion, amortization of prepaid lease purchase price adjustments, interest expense and amortization of deferred financing costs, net, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, impairment of available-for-sale securities, interest income, other (income) expense, (benefit) provision for income taxes, (income) loss from discontinued operations, net of tax, cumulative effect of a change in accounting principle and stock-based compensation expense, net, recorded in consolidated site rental costs of operations, less services and other revenues.

We define Adjusted Services and Other Gross Margin as net income (loss) plus site rental costs of operations, selling, general and administrative expenses, restructuring charges (credits), asset write-down charges, goodwill impairment, acquisition and integration costs, depreciation, amortization and accretion, interest expense and amortization of deferred financing costs, net, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, impairment of available-for-sale securities, interest income, other (income) expense, (benefit) provision for income taxes, (income) loss from discontinued operations, net of tax, cumulative effect of a change in accounting principle and stock-based compensation expense, net, recorded in consolidated services and other costs of operations, less site rental revenues.

We use Adjusted Site Rental Gross Margin and Adjusted Services and Other Gross Margin, which are non-GAAP financial measures, as indicators of financial performance. Our measures of Adjusted Site Rental Gross Margin and Adjusted Services and Other Gross Margin may not be comparable to similarly titled measures of other companies, including companies in the towers sector or other REITs, and are not measures of performance calculated in accordance with GAAP. There are material limitations to using measures such as Adjusted Site Rental Gross Margin and Adjusted Services and Other Gross Margin, including the difficulty associated with comparing results among more than one company, including our competitors, and the inability to analyze certain significant items, including selling, general and administrative expenses and depreciation, amortization, and accretion, that directly affect our net income (loss). Management compensates for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with their analysis of net income (loss). The reconciliations of Adjusted Site Rental Gross Margin and Adjusted Services and Other Gross Margin to our net income (loss) are set forth below:

We believe Adjusted Site Rental Gross Margin and Adjusted Services and Other Gross Margin are useful to investors or other interested parties in evaluating our financial performance because:

i.they are measures used by our management (1) to evaluate the economic productivity of our business, (2) to identify underlying business trends that are impacting our performance, and (3) for purposes of making decisions about allocating resources to, and assessing the performance of, our business; and

ii.we believe it helps investors and other interested parties meaningfully evaluate and compare the results of our operations from period to period.

Our management uses Adjusted Site Rental Gross Margin and Adjusted Services and Other Gross Margin:

i.as a measurement of financial performance because it assists us in comparing our financial performance excluding the impact of certain non-cash items such as stock-based compensation expense, net and amortization of prepaid lease purchase price adjustments and asset base (primarily depreciation, amortization and accretion) from our operating results and before consideration of selling, general and administrative expenses;

ii.in the evaluation pricing of new projects and new tenant agreements; and

iii.for planning purposes, including preparation of our annual operating budget.

We define earnings before interest, taxes, depreciation, amortization and accretion, as adjusted ("Adjusted EBITDA") as net income (loss) plus restructuring charges (credits), asset write-down charges, goodwill impairment, acquisition and integration costs, depreciation, amortization and accretion, amortization of prepaid lease purchase price adjustments, interest expense and amortization of deferred financing costs, net, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, impairment of available-for-sale securities, interest income, other (income) expense, (benefit) provision for income taxes, net (income) loss from discontinued operations, (gain) loss on sale of discontinued operations, cumulative effect of a change in accounting principle, stock-based compensation expense, net and net (gain) loss from disposal of discontinued operations, net of tax.

We use Adjusted EBITDA, which is a non-GAAP financial measure, as an indicator of consolidated financial performance. Our measure of Adjusted EBITDA may not be comparable to similarly titled measures of other companies, including companies in the tower sector or other REITs, and is not a measure of performance calculated in accordance with GAAP. Adjusted EBITDA should not be considered in isolation or as a substitute for operating income (loss), net income (loss), net cash provided by (used for) operating, investing and financing activities or other income statement or cash flow statement data prepared in accordance with GAAP and should be considered only as a supplement to net income (loss) computed in accordance with GAAP as a measure of our performance. There are material limitations to using a measure such as Adjusted EBITDA, including the difficulty associated with comparing results among more than one company, including our competitors, and the inability to analyze certain significant items, including depreciation and interest expense, that directly affect our net income (loss). Management compensates for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with their analysis of net income (loss). The reconciliation of Adjusted EBITDA to our net income (loss) is set forth below:

(a)The above reconciliation excludes the items included in our Adjusted EBITDA definition which are not applicable to the periods shown.

We believe Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance because:

•they are frequently used by our management (1) to evaluate the economic productivity of our operations and (2) for purposes of making decisions about allocating resources to, and assessing the performance of, our operations;

•although specific definitions may vary, it is widely used by investors or other interested parties in evaluation of the tower sector and other REITs to measure financial performance without regard to items such as depreciation, amortization and accretion, which can vary depending upon accounting methods and the book value of assets;

•we believe it helps investors and other interested parties meaningfully evaluate and compare the results of our operations (1) from period to period and (2) to our competitors by removing the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our financial results; and

•they are similar to the measure of current financial performance generally used in our debt covenant calculations.

Our management uses Adjusted EBITDA:

•as a component in the employee annual incentive compensation calculation;

51

•as a measurement of financial performance because it assists us in comparing our financial performance on a consistent basis as it removes the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our operating results;

•in presentations to our board of directors to enable it to have the same measurement of financial performance used by management;

•for planning purposes, including preparation of our annual operating budget;

•as a valuation measure in strategic analyses in connection with the purchase and sale of assets;

•in determining self-imposed limits on our debt levels, including the evaluation of our leverage ratio; and

•with respect to compliance with our debt covenants, which require us to maintain certain financial ratios that incorporate concepts such as, or similar to, Adjusted EBITDA.
