COMPANY PROFILE

Crown Castle Inc. (to which the terms "Crown Castle," "CCI," "we," "our," "the Company" or "us" as used herein refer) owns, operates and leases shared communications infrastructure that is geographically dispersed throughout the U.S., including (1) more than 40,000 towers and other structures, such as rooftops (collectively, "towers"), (2) approximately 115,000 small cells on air or under contract and (3) approximately 90,000 route miles of fiber primarily supporting small cells and fiber solutions. We refer to our towers, small cells and fiber assets collectively as "communications infrastructure," and to our customers on our communications infrastructure as "tenants." Our towers have a significant presence in each of the top 100 basic trading areas, and the majority of our small cells and fiber assets are located in major metropolitan areas, including a presence within every major U.S. market.

Our operating segments consist of (1) Towers and (2) Fiber, which includes both small cells and fiber solutions. Our core business is providing access, including space or capacity, to our shared communications infrastructure via long-term contracts in various forms, including lease, license, sublease and service agreements (collectively, "tenant contracts"). We seek to increase our site rental revenues by adding more tenants on our shared communications infrastructure, which we expect to result in significant incremental cash flows due to our low incremental operating costs.

We operate as a Real Estate Investment Trust ("REIT") for U.S. federal income tax purposes.

STRATEGY

As a leading provider of shared communications infrastructure 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 portfolio of communications infrastructure, (2) returning a meaningful portion of our cash generated by operating activities to our common stockholders in the form of dividends and (3) investing capital efficiently to grow cash flows and long-term dividends per share. Our strategy is based, in part, on our belief that the U.S. is the most attractive market for shared communications infrastructure investment with the greatest long-term growth potential. We measure our efforts to create "long-term stockholder value" by the combined payment of dividends to stockholders and growth in our per-share results. The key elements of our strategy are to:

•Grow cash flows from our existing communications infrastructure. We are focused on maximizing the recurring site rental cash flows generated from providing our tenants with long-term access to our shared infrastructure assets, which we believe is the core driver of value for our stockholders. Tenant additions or modifications of existing tenant equipment (collectively, "tenant additions") enable our tenants to expand coverage and capacity in order to meet increasing demand for data while generating high incremental returns for our business. We believe our product offerings of towers and small cells provide a comprehensive solution to our wireless tenants' growing network needs through our shared communications infrastructure model, which is an efficient and cost-effective way to serve our tenants. Additionally, we believe our ability to share our fiber assets across multiple tenants to deploy both small cells and offer fiber solutions allows us to generate cash flows and increase stockholder return.

•Return cash generated by operating activities to common stockholders in the form of dividends. We believe that distributing a meaningful portion of our cash generated by operating activities appropriately provides common stockholders with increased certainty for a portion of expected long-term stockholder value while still allowing us to retain sufficient flexibility to invest in our business and deliver growth. We believe this decision reflects the translation of the high-quality, long-term contractual cash flows of our business into stable capital returns to common stockholders.

•Invest capital efficiently to grow cash flows and long-term dividends per share. In addition to adding tenants to existing communications infrastructure, we seek to invest our available capital, including the net cash generated by our operating activities and external financing sources, in a manner that will increase long-term stockholder value on a risk-adjusted basis. These investments include constructing and acquiring new communications infrastructure that we expect will generate future cash flow growth and attractive long-term returns by adding tenants to those assets over time. Our historical investments have included the following (in no particular order):

◦construction of towers, fiber and small cells;

◦acquisitions of towers, fiber and small cells;

◦acquisitions of land interests (which primarily relate to land assets under towers);

◦improvements and structural enhancements to our existing communications infrastructure;

◦purchases of shares of our common stock from time to time; and

◦purchases, repayments or redemptions of our debt.

Our strategy to create long-term stockholder value is based on our belief that there will be considerable future demand for our communications infrastructure based on the location of our assets and the rapid and continuing growth in the demand for data. We believe that such demand for our communications infrastructure will continue, will result in growth of our cash flows due to tenant additions on our existing communications infrastructure, and will create other growth opportunities for us, such as demand for newly constructed or acquired communications infrastructure, as described above. Further, we seek to augment the long-term value creation associated with growing our recurring site rental cash flows by offering certain ancillary site development services within our Towers segment.

(a)In addition, we have the following sources of liquidity:

i.In March 2021, we established an at-the-market stock offering program ("ATM Program") through which we may, from time to time, issue and sell shares of our common stock having an aggregate gross sales price of up to $750 million to or through sales agents. No shares of common stock have been sold under the ATM Program.

ii.In April 2019, we established a CP Program through which we may issue short term, unsecured CP Notes. Amounts available under the CP Program may be issued, repaid and re-issued from time to time, with the aggregate principal amount of CP Notes outstanding under the CP Program at any time not to exceed $2.0 billion. As of December 31, 2023, there were no CP Notes outstanding under our CP Program. We intend to maintain available commitments under our 2016 Revolver in an amount at least equal to the amount of CP Notes outstanding at any point in time.

(b)Inclusive of $5 million included within "Other assets, net" on our condensed consolidated balance sheet.

(c)Availability at any point in time is subject to reaffirmation of the representations and warranties in, and there being no default under, the credit agreement governing our 2016 Revolver.

(d)See "Non-GAAP Measures and Other Information" for further information on, and reconciliation to, Net Debt.

(e)As defined in the respective debt agreement. In the indentures for the 2015 Tower Revenue Notes, 2018 Tower Revenue Notes and the 2009 Securitized Notes, the defined term for Debt Service Coverage Ratio is "DSCR." Total Net Leverage Ratio, Total Senior Secured Leverage Ratio and all DSCR ratios are calculated using the trailing twelve months.

(f)Failure to comply with the financial maintenance covenants would, absent a waiver, result in an event of default under the credit agreement governing our 2016 Credit Facility.

(g)Applicable solely to the extent that the senior unsecured debt rating by any two of S&P, Moody's and Fitch is lower than BBB-, Baa3 or BBB-, respectively. If applicable, the consolidated interest coverage ratio must be greater than or equal to 2.50.

(h)The 2015 Tower Revenue Notes, 2018 Tower Revenue Notes and 2009 Securitized Notes also include the potential for amortization events, which could result in applying current and future cash flow to the prepayment of debt with applicable prepayment consideration. An amortization event occurs when the Debt Service Coverage Ratio falls below 1.45x, 1.45x or 1.15x, in each case as described under the indentures for the 2015 Tower Revenue Notes, 2018 Tower Revenue Notes or 2009 Securitized Notes, respectively.

(i)Rating Agency Confirmation (as defined in the respective debt agreement) is required.

NON-GAAP MEASURES AND OTHER INFORMATION

This Supplement includes presentations of Adjusted EBITDA, Adjusted Funds from Operations ("AFFO"), including per share amounts, Funds from Operations ("FFO"), including per share amounts, Organic Contribution to Site Rental Billings, including as Adjusted for Impact of Sprint Cancellations, Net Debt, Net Debt to Last Quarter Annualized Adjusted EBITDA, Consolidated Return on Invested Capital and Segment Cash Yield on Invested Capital, which are non-GAAP financial measures. These non-GAAP financial measures are not intended as alternative measures of operating results or cash flow from operations (as determined in accordance with Generally Accepted Accounting Principles ("GAAP")).

Our non-GAAP financial measures may not be comparable to similarly titled measures of other companies, including other companies in the communications infrastructure sector or other REITs.

In addition to the non-GAAP financial measures used herein, we also provide segment site rental gross margin, segment services and other gross margin and segment operating profit, which are key measures used by management to evaluate our operating segments. These segment measures are provided pursuant to GAAP requirements related to segment reporting. In addition, we provide the components of certain GAAP measures, such as site rental revenues and capital expenditures.

Our non-GAAP financial measures are presented as additional information because management believes these measures are useful indicators of the financial performance of our business. Among other things, management believes that:

•Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance. Adjusted EBITDA is the primary measure used by 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. Management believes that Adjusted EBITDA helps investors or 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. Management also believes Adjusted EBITDA is frequently used by investors or other interested parties in the evaluation of the communications infrastructure 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. In addition, Adjusted EBITDA is similar to the measure of current financial performance generally used in our debt covenant calculations. Adjusted EBITDA should be considered only as a supplement to net income (loss) computed in accordance with GAAP as a measure of our performance.

•AFFO, including per share amounts, is useful to investors or other interested parties in evaluating our financial performance. Management believes that AFFO helps investors or other interested parties meaningfully evaluate our financial performance as it includes (1) the impact of our capital structure (primarily interest expense on our outstanding debt and dividends on our preferred stock (in periods where applicable)) and (2) sustaining capital expenditures, and excludes the impact of our (1) asset base (primarily depreciation, amortization and accretion) and (2) certain non-cash items, including straight-lined revenues and expenses related to fixed escalations and rent free periods. GAAP requires rental revenues and expenses related to leases that contain specified rental increases over the life of the lease to be recognized evenly over the life of the lease. In accordance with GAAP, if payment terms call for fixed escalations or rent free periods, the revenues or expenses are recognized on a straight-lined basis over the fixed, non-cancelable term of the contract. Management notes that Crown Castle uses AFFO only as a performance measure. AFFO should be considered only as a supplement to net income (loss) computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flow from operations or as residual cash flow available for discretionary investment.

•FFO, including per share amounts, is useful to investors or other interested parties in evaluating our financial performance. Management believes that FFO may be used by investors or other interested parties as a basis to compare our financial performance with that of other REITs. FFO helps investors or other interested parties meaningfully evaluate financial performance by excluding the impact of our asset base (primarily real estate depreciation, amortization and accretion). FFO is not a key performance indicator used by Crown Castle. FFO should be considered only as a supplement to net income (loss) computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flow from operations.

•Organic Contribution to Site Rental Billings is useful to investors or other interested parties in understanding the components of the year-over-year changes in our site rental revenues computed in accordance with GAAP. Management uses Organic Contribution to Site Rental Billings to assess year-over-year growth rates for our rental activities, to evaluate current performance, to capture trends in rental rates, core leasing activities and tenant non-renewals in our core business, as well as to forecast future results. Separately, we are also disclosing Organic Contribution to Site Rental Billings as Adjusted for Impact of Sprint Cancellations, which is outside of ordinary course, to provide further insight into our results of operations and underlying trends. Management believes that identifying the impact for Sprint Cancellations provides increased transparency and comparability across periods. Organic Contribution to Site Rental Billings (including as Adjusted for Impact of Sprint Cancellations) is not meant as an alternative measure of revenue and should be considered only as a supplement in understanding and assessing the performance of our site rental revenues computed in accordance with GAAP.

•Net Debt is useful to investors or other interested parties in evaluating our overall debt position and future debt capacity. Management uses Net Debt in assessing our leverage. Net Debt is not meant as an alternative measure of debt and should be considered only as a supplement in understanding and assessing our leverage.

OVERVIEW OUTLOOK  CONSOLIDATED FINANCIALS CAPITALIZATION OVERVIEW TOWERS SEGMENT FIBER SEGMENT APPENDIX

•Net Debt to Last Quarter Annualized Adjusted EBITDA is useful to investors or other interested parties, specifically credit rating agencies, in analyzing our operating performance in the context of targeted financial leverage. Management uses Net Debt to Last Quarter Annualized Adjusted EBITDA in assessing our leverage. Net Debt to Last Quarter Annualized Adjusted EBITDA is not meant as an alternative to GAAP measures such as debt and net income (loss) computed in accordance with GAAP. Net Debt to Last Quarter Annualized Adjusted EBITDA should be considered only as a supplement in understanding and assessing our leverage.

•Consolidated Return on Invested Capital and Segment Cash Yield on Invested Capital are useful to investors or other interested parties in evaluating the financial performance of our assets. Management believes that these metrics are useful in assessing our efficiency at allocating capital to generate returns over time. Consolidated Return on Invested Capital and Segment Cash Yield on Invested Capital are not meant as alternatives to GAAP measures such as revenues, operating income, segment site rental gross margin, and certain asset classes (such as property and equipment, site rental contracts and tenant relationships, and goodwill) computed in accordance with GAAP. Such non-GAAP metrics should be considered only as a supplement in understanding and assessing the performance of our assets.

Non-GAAP Financial Measures

Adjusted EBITDA. We define Adjusted EBITDA as net income (loss) plus restructuring charges (credits), asset write-down charges, 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 and stock-based compensation expense, net.

AFFO. We define AFFO as FFO before straight-lined revenues, straight-lined expenses, stock-based compensation expense, net, non-cash portion of tax provision, non-real estate related depreciation, amortization and accretion, amortization of non-cash interest expense, other (income) expense, (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, acquisition and integration costs, restructuring charges (credits), net (income) loss from discontinued operations, (gain) loss on sale of discontinued operations, cumulative effect of a change in accounting principle and adjustments for noncontrolling interests, less sustaining capital expenditures.

AFFO per share. We define AFFO per share as AFFO divided by diluted weighted-average common shares outstanding.

FFO. We define FFO as net income (loss) plus real estate related depreciation, amortization and accretion and asset write-down charges, less noncontrolling interest and cash paid for preferred stock dividends (in periods where applicable), and is a measure of funds from operations attributable to common stockholders.

FFO per share. We define FFO per share as FFO divided by diluted weighted-average common shares outstanding.

Organic Contribution to Site Rental Billings. We define Organic Contribution to Site Rental Billings as the sum of the change in site rental revenues related to core leasing activity, escalators and payments for Sprint Cancellations, less non-renewals of tenant contracts and non-renewals associated with Sprint Cancellations. Additionally, Organic Contribution to Site Rental Billings as Adjusted for Impact of Sprint Cancellations reflects Organic Contribution to Site Rental Billings less payments for Sprint Cancellations, plus non-renewals associated with Sprint Cancellations.

Net Debt. We define Net Debt as (1) debt and other long-term obligations and (2) current maturities of debt and other obligations, excluding unamortized adjustments, net; less cash, cash equivalents and restricted cash.

Net Debt to Last Quarter Annualized Adjusted EBITDA. We define Net Debt to Last Quarter Annualized Adjusted EBITDA as Net Debt divided by the most recent quarter's Adjusted EBITDA multiplied by four.

Consolidated Invested Capital. We define Consolidated Invested Capital as the historical gross investment in (1) property and equipment (excluding the impact of construction in process), (2) site rental contracts and tenant relationships and (3) goodwill.

Consolidated Return on Invested Capital. We define Consolidated Return on Invested Capital as Adjusted EBITDA less cash taxes paid divided by Consolidated Invested Capital.

Segment Net Invested Capital. We define Segment Net Invested Capital as the investment in (1) property and equipment, excluding the impact of construction in process and non-productive assets (such as information technology assets and buildings), reduced by the amount of prepaid rent received from tenants (excluding any deferred credits recorded in connection with acquisitions), (2) site rental contracts and tenant relationships, and (3) goodwill, excluding the impact of certain assets and liabilities recorded in connection with acquisitions (primarily deferred credits).

Segment Cash Yield on Invested Capital. We define Segment Cash Yield on Invested Capital as segment site rental gross margin adjusted for the impacts of (1) amortization of prepaid rent, (2) straight-lined revenues, (3) straight-lined expenses and (4) indirect labor costs related to the Fiber segment divided by Segment Net Invested Capital.

Segment services and other gross margin. We define segment services and other gross margin as segment services and other revenues less segment services and other costs of operations, excluding stock-based compensation expense, net recorded in consolidated services and other costs of operations.

Segment operating profit. We define segment operating profit as segment site rental gross margin plus segment services and other gross margin, less segment selling, general and administrative expenses.

All of these measurements of profit or loss are exclusive of depreciation, amortization and accretion, which are shown separately. Additionally, certain costs are shared across segments and are reflected in our segment measures through allocations that management believes to be reasonable.

Other Information

Site rental billings. We define site rental billings as site rental revenues exclusive of the impacts from (1) straight-lined revenues, (2) amortization of prepaid rent in accordance with GAAP and (3) contribution from recent acquisitions until the one-year anniversary of such acquisitions.

Core leasing activity. We define core leasing activity as site rental revenues growth from tenant additions across our entire portfolio and renewals or extensions of tenant contracts, exclusive of (1) the impacts from both straight-lined revenues and amortization of prepaid rent in accordance with GAAP and (2) payments for Sprint Cancellations, where applicable.

Non-renewals. We define non-renewals of tenant contracts as the reduction in site rental revenues as a result of tenant churn, terminations and, in limited circumstances, reductions of existing lease rates, exclusive of non-renewals associated with Sprint Cancellations, where applicable.

Discretionary capital expenditures. We define discretionary capital expenditures as those capital expenditures made with respect to activities which we believe exhibit sufficient potential to enhance long-term stockholder value. They primarily consist of expansion or development of 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 relates 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.

Sustaining capital expenditures. We define sustaining capital expenditures as those capital expenditures 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.

Sprint Cancellations. We define Sprint Cancellations as lease cancellations related to the previously disclosed T-Mobile US, Inc. and Sprint network consolidation as described in our press release dated April 19, 2023.
