"Capitalizing on the momentum created by a robust 5G leasing environment, we were able to deliver another solid quarter in the second quarter and increase our full year 2021 Outlook for AFFO per share growth to 12%," stated Jay Brown, Crown Castle’s Chief Executive Officer. "We are seeing the highest level of tower activity in our history as our customers are focusing on utilizing towers in the first phase of deploying their 5G networks nationwide. This initial focus on towers has led to delays in some of our small cell deployments that impact the timing of when we expect to complete the nearly 30,000 small cells currently in our backlog. We continue to believe the deployment of 5G in the U.S. will extend our opportunity to create value for our shareholders as our ability to offer towers, small cells and fiber solutions, which are all integral components of communications networks, will be critical as our customers densify their networks to deliver 5G. Our diverse portfolio of assets and customer solutions has enabled us to outperform our long-term target growth rate of 7% to 8% since we established the target in 2017, demonstrating how well positioned Crown Castle is to capitalize on the robust demand for connectivity. During that period, we have grown dividends per share at a compounded annual growth rate of 9%,

and, going forward, we believe our strategy will allow us to deliver on our long-term target dividend per share growth of 7% to 8% per year."

HIGHLIGHTS FROM THE QUARTER
Site rental revenues. Site rental revenues grew 8%, or $106 million, from second quarter 2020 to second quarter 2021, inclusive of approximately $70 million in Organic Contribution to Site Rental Revenues and a $35 million increase in straight-lined revenues. The $70 million in Organic Contribution to Site Rental Revenues represents approximately 5.3% growth, comprised of approximately 8.6% growth from new leasing activity and contracted tenant escalations, net of approximately 3.3% from tenant non-renewals.
Income from continuing operations. Income from continuing operations for the second quarter 2021 was $333 million compared to $200 million for the second quarter 2020 and was predominantly impacted by the increase in site rental revenues and services contribution.
AFFO per share. AFFO per share for the second quarter 2021 was $1.71, representing 18% growth when compared to $1.45 for the second quarter 2020.
Capital Expenditures. Capital expenditures during the quarter were $308 million, comprised of $19 million of sustaining capital expenditures and $289 million of discretionary capital expenditures. Discretionary capital expenditures during the quarter primarily included approximately $223 million attributable to Fiber and approximately $60 million attributable to Towers.
Common stock dividend. During the quarter, Crown Castle paid common stock dividends of approximately $575 million in the aggregate, or $1.33 per common share, an increase of approximately 11% on a per share basis compared to the same period a year ago.
Financing Activities. In June, Crown Castle issued $750 million in aggregate principal amount of senior unsecured notes with a 10-year maturity and a coupon of 2.500% and extended the maturity date on its Senior Unsecured Credit Facility to June 2026. Net proceeds from the senior notes offering were used to repay all of the outstanding Senior Secured Tower Revenue Notes, Series 2015-1, Class C-2022 in July, to repay outstanding commercial paper notes at their maturity date, and for general corporate purposes.
"We are excited about the level of activity we see in our business as our customers are deploying 5G at scale," stated Dan Schlanger, Crown Castle's Chief Financial Officer. "We believe we are well positioned to support our customers by providing a comprehensive set of solutions across towers, small cells and fiber solutions, which are all necessary to build out 5G wireless networks. The elevated level of Towers activity this year is contributing to an expected 12% growth in AFFO per share, meaningfully exceeding our long-term target of 7% to 8% per year.

Looking forward, we believe we are in a great position to deliver on our growth target while at the same time making investments in our business that we believe will generate attractive long-term returns and support future growth. We continue to take steps to complement our compelling total return opportunity with a lower risk profile, which includes allocating capital to opportunities in the U.S., which we believe is the best market for communications infrastructure ownership, and extends to how we manage the balance sheet. To that point, we were able to opportunistically access the bond market and extend the maturity on our credit facility during the second quarter, extending our debt maturity profile and reducing our overall cost of capital."

The primary contributors to the increase in the full year 2021 Outlook include the contribution from $15 million of additional straight-lined revenues and a $45 million increase in the expected services contribution associated with higher Towers activity than previously expected, offset by a $10 million reduction in the expected Organic Contribution to Site Rental Revenues primarily attributable to small cell deployment delays and $15 million of additional costs primarily associated with the higher Towers activity.
We now expect to deploy approximately 5,000 small cells in 2021 compared to our prior expectations of approximately 10,000 small cells. The decrease is attributable to a combination of a change in customer priorities - primarily as a result of their focus on utilizing towers in the first phase of their 5G deployments, zoning and permitting challenges, and the previously disclosed Sprint Cancellation that included approximately 1,000 Sprint small cells initially scheduled for deployment during 2021.
As a result of the Sprint Cancellation and our anticipation that our customers will continue to focus on utilizing towers in the early stages of their 5G rollouts, we expect to deploy a similar number of small cell nodes in 2022 as 2021. We believe these impacts are temporary and will not affect our ability to deliver our full backlog of nearly 30,000 contractually committed small cells over time.
The chart below reconciles the components of expected growth in site rental revenues from 2020 to 2021 of $360 million to $405 million, inclusive of expected Organic Contribution to Site Rental Revenues during 2021 of $280 million to $320 million, or approximately 5.7%. The consolidated growth is comprised of approximately 6% from towers (unchanged from previous Outlook), approximately 10% from small cells (compared to previous Outlook of approximately 13%), and approximately 3% from fiber solutions (unchanged from previous Outlook).

https://cdn.kscope.io/c013837b556c593636ce65f70ef7ec5d-revenuegrowthq22021a.jpg
New leasing activity is expected to contribute $360 million to $390 million to 2021 Organic Contribution to Site Rental Revenues, consisting of new leasing activity from towers of $150 million to $160 million (unchanged from previous Outlook), small cells of $50 to $60 million (compared to previous Outlook of $65 million to $75 million), and fiber solutions of $160 million to $170 million (unchanged from previous Outlook).
The chart below reconciles the components of expected growth in AFFO from 2020 to 2021 of $360 million to $405 million, adjusted to exclude the impact of the Nontypical Items discussed in our press release dated January 27, 2021.

Non-GAAP Financial Measures, Segment Measures and Other Calculations
This press release includes presentations of Income (loss) from continuing operations (as adjusted), including per share—diluted amounts, Adjusted EBITDA, Adjusted Funds from Operations ("AFFO"), including per share amounts, Funds from Operations ("FFO"), including per share amounts, and Organic Contribution to Site Rental Revenues, 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 real estate investment trusts ("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 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:
Income (loss) from continuing operations (as adjusted), including per share—diluted amounts, is useful to investors and other interested parties in evaluating our financial performance. Management believes that this measure is meaningful to investors as it adjusts Income (loss) from continuing operations to exclude the impact of the Nontypical Items (as defined in this press release and described further in our press release dated January 27, 2021), which management believes are unusual (including with respect to magnitude), infrequent and not reasonably likely to recur in the near term, to provide further insight into our results of operations and underlying trends and projections. Management also believes that identifying the impact of Nontypical Items as adjustments provides more transparency and comparability across periods. There can be no assurances that such items will not recur in future periods. Income (loss) from continuing operations (as adjusted), including per share—diluted amounts should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
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. Separately, we are also disclosing Adjusted EBITDA as adjusted to exclude the impact of Nontypical Items, which management believes are unusual (including with respect to magnitude), infrequent and not reasonably likely to recur in the near term, to provide further insight into our results of operations and underlying trends and projections. Management also believes that identifying the impact of Nontypical Items as adjustments provides increased transparency and comparability across periods. There can be no assurances that such items will not recur in future periods. Adjusted EBITDA (including as further adjusted to exclude Nontypical Items) should be considered only as a supplement to net income 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 (a) asset base (primarily depreciation, amortization and accretion) and (b) 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 revenue or expense is 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.

Separately, we are also disclosing AFFO as adjusted to exclude the impact of Nontypical Items, which management believes are unusual (including with respect to magnitude), infrequent and not reasonably likely to recur in the near term, to provide further insight into our results of operations and underlying trends and projections. Management also believes that identifying the impact of Nontypical Items as adjustments provides increased transparency and comparability across periods. There can be no assurances that such items will not recur in future periods. AFFO (including as further adjusted to exclude Nontypical Items) should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flows 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 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 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 Revenues 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 the Organic Contribution to Site Rental Revenues to assess year-over-year growth rates for our rental activities, to evaluate current performance, to capture trends in rental rates, new leasing activities and tenant non-renewals in our core business, as well to forecast future results. Organic Contribution to Site Rental Revenues 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.
We define our non-GAAP financial measures, segment measures and other calculations as follows:
Non-GAAP Financial Measures
Income (loss) from continuing operations (as adjusted). We define Income (loss) from continuing operations (as adjusted) as Income (loss) from continuing operations less other operating income resulting from the Nontypical Items, plus incremental operating expenses and asset write-downs as a result of the Nontypical Items.
Income (loss) from continuing operations (as adjusted) per share—diluted. We define Income (loss) from continuing operations (as adjusted) per sharediluted as Income (loss) from continuing operations (as adjusted), divided by diluted weighted-average common shares outstanding.
Adjusted EBITDA. We define Adjusted EBITDA as Income (loss) from continuing operations 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, (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, cumulative effect of a change in accounting principle and stock-based compensation expense. Separately, Adjusted EBITDA, as adjusted to exclude the impact of Nontypical Items, reflects Adjusted EBITDA, less other operating income resulting from the Nontypical Items, plus incremental operating expenses as a result of the Nontypical Items.
Adjusted Funds from Operations. We define Adjusted Funds from Operations as FFO before straight-lined revenue, straight-lined expense, stock-based compensation expense, 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), cumulative effect of a change in accounting principle and adjustments for noncontrolling interests, less sustaining capital expenditures. Separately, Adjusted Funds from Operations, as adjusted to exclude the impact of Nontypical Items, reflects Adjusted Funds from Operations, less other operating income resulting from the Nontypical Items, plus incremental operating expenses as a result of the Nontypical Items.
AFFO per share. We define AFFO per share as AFFO, including as adjusted to exclude the impact of Nontypical Items, divided by diluted weighted-average common shares outstanding.
Funds from Operations. We define Funds from Operations as Income (loss) from continuing operations 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 CCIC common stockholders.
FFO per share. We define FFO per share as FFO divided by the diluted weighted-average common shares outstanding.
Organic Contribution to Site Rental Revenues. We define the Organic Contribution to Site Rental Revenues as the sum of the change in GAAP site rental revenues related to (1) new leasing activity, including revenues from the construction of small cells and the impact of prepaid rent, (2) escalators and less (3) non-renewals of tenant contracts.
Segment Measures
Segment Site Rental Gross Margin. We define Segment Site Rental Gross Margin as segment site rental revenues less segment site rental cost of operations, excluding stock-based compensation expense and prepaid lease purchase price adjustments recorded in consolidated site rental cost of operations.
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 cost of operations, excluding stock-based compensation expense recorded in consolidated services and other cost of operations.
Segment Operating Profit. We define Segment Operating Profit as segment site rental gross margin plus segment services and other gross margin, and segment other operating (income) expense, less selling, general and administrative expenses attributable to the respective segment.
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 Calculations
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.

Cautionary Language Regarding Forward-Looking Statements
This news release contains forward-looking statements and information that are based on our management's current expectations as of the date of this news release. Statements that are not historical facts are hereby identified as forward-looking statements. In addition, words such as "estimate," "see," "anticipate," "project," "plan," "intend," "believe," "expect," "likely," "predicted," "positioned," "continue," "target," and any variations of these words and similar expressions are intended to identify forward-looking statements. Such statements include our full year 2021 Outlook and plans, projections, and estimates regarding (1) potential benefits, growth, returns, capabilities, opportunities and shareholder value which may be derived from our business, strategy, risk profile, assets and customer solutions, investments, acquisitions and dividends, (2) our business, strategy, strategic position, business model and capabilities and the strength thereof, (3) industry fundamentals and driving factors for improvements in such fundamentals, (4) 5G deployment in the United States and our customers' strategy with respect thereto and demand for our assets and solutions created thereby, (5) our long-and short-term prospects and the trends, events and industry activities impacting our business, (6) opportunities we see to deliver value to our shareholders, (7) our dividends (including timing of payment thereof) and our long- and short-term dividend (including on a per share basis) growth rate, including its driving factors, and targets, (8) revenue growth in the Towers segment, (9) debt maturities, (10) strategic position of our portfolio of assets, (11) cash flows, including growth thereof, (12) leasing environment and the activity we see in our business, and benefits and opportunities created thereby, (13) tenant non-renewals, including the impact and timing thereof, (14) capital expenditures, including sustaining and discretionary capital expenditures, the timing thereof and any benefits that may result therefrom, (15) straight-line adjustments, (16) revenues and growth thereof and benefits derived therefrom, (17) the recurrence and impact of Nontypical Items, (18) income (loss) from continuing operations (including on a per share basis and as adjusted for Nontypical Items), (19) Adjusted EBITDA (including as adjusted for Nontypical Items), including components thereof and growth thereof, (20) costs and expenses, including interest expense and amortization of deferred financing costs, (21) FFO (including on a per share basis) and growth thereof, (22) AFFO (including on a per share basis and as adjusted for Nontypical Items) and its components and growth thereof and corresponding driving factors, (23) Organic Contribution to Site Rental Revenues and its components, including growth thereof and contributions therefrom, (24) our weighted-average common shares outstanding (including on a diluted basis) and growth thereof, (25) services contribution, (26) small cells backlog (including our ability to ultimately deploy all of the small cells currently in our backlog) and the timing of small cell deployment, (27) the strength of the U.S. market for communications infrastructure ownership and (28) the utility of certain financial measures, including non-GAAP financial measures. All future dividends are subject to declaration by our board of directors.
Such forward-looking statements are subject to certain risks, uncertainties and assumptions, including prevailing market conditions and the following:
Our business depends on the demand for our communications infrastructure, driven primarily by demand for data, and we may be adversely affected by any slowdown in such demand. Additionally, a reduction in the amount or change in the mix of network investment by our tenants may materially and adversely affect our business (including reducing demand for our communications infrastructure or services).
A substantial portion of our revenues is derived from a small number of tenants, and the loss, consolidation or financial instability of any of such tenants may materially decrease revenues or reduce demand for our communications infrastructure and services.
The expansion or development of our business, including through acquisitions, increased product offerings or other strategic growth opportunities, may cause disruptions in our business, which may have an adverse effect on our business, operations or financial results.
Our Fiber segment has expanded rapidly, and the Fiber business model contains certain differences from our Towers business model, resulting in different operational risks. If we do not successfully operate our Fiber business model or identify or manage the related operational risks, such operations may produce results that are lower than anticipated.
Failure to timely, efficiently and safely execute on our construction projects could adversely affect our business.
Our substantial level of indebtedness could adversely affect our ability to react to changes in our business, and the terms of our debt instruments limit our ability to take a number of actions that our management might otherwise believe to be in our best interests. In addition, if we fail to comply with our covenants, our debt could be accelerated.
We have a substantial amount of indebtedness. In the event we do not repay or refinance such indebtedness, we could face substantial liquidity issues and might be required to issue equity securities or securities convertible into equity securities, or sell some of our assets to meet our debt payment obligations.
Sales or issuances of a substantial number of shares of our common stock or securities convertible into shares of our common stock may adversely affect the market price of our common stock.
As a result of competition in our industry, we may find it more difficult to negotiate favorable rates on our new or renewing tenant contracts.

New technologies may reduce demand for our communications infrastructure or negatively impact our revenues.
If we fail to retain rights to our communications infrastructure, including the rights to land under our towers and the right-of-way and other agreements related to our small cells and fiber, our business may be adversely affected.
Our services business has historically experienced significant volatility in demand, which reduces the predictability of our results.
The restatement of our previously issued financial statements, the errors that resulted in such restatement, the material weakness that was previously identified in our internal control over financial reporting and the determination that our internal control over financial reporting and disclosure controls and procedures were not effective, could result in loss of investor confidence, shareholder litigation or governmental proceedings or investigations, any of which could cause the market value of our common stock or debt securities to decline or impact our ability to access the capital markets.
New wireless technologies may not deploy or be adopted by tenants as rapidly or in the manner projected.
If we fail to comply with laws or regulations which regulate our business and which may change at any time, we may be fined or even lose our right to conduct some of our business.
If radio frequency emissions from wireless handsets or equipment on our communications infrastructure are demonstrated to cause negative health effects, potential future claims could adversely affect our operations, costs or revenues.
Certain provisions of our restated certificate of incorporation, amended and restated by-laws and operative agreements, and domestic and international competition laws may make it more difficult for a third party to acquire control of us or for us to acquire control of a third party, even if such a change in control would be beneficial to our stockholders.
We may be vulnerable to security breaches or other unforeseen events that could adversely affect our operations, business, and reputation.
Future dividend payments to our stockholders will reduce the availability of our cash on hand available to fund future discretionary investments, and may result in a need to incur indebtedness or issue equity securities to fund growth opportunities. In such event, the then current economic, credit market or equity market conditions will impact the availability or cost of such financing, which may hinder our ability to grow our per share results of operations.
Remaining qualified to be taxed as a REIT involves highly technical and complex provisions of the U.S. Internal Revenue Code. Failure to remain qualified as a REIT would result in our inability to deduct dividends to stockholders when computing our taxable income, which would reduce our available cash.
Complying with REIT requirements, including the 90% distribution requirement, may limit our flexibility or cause us to forgo otherwise attractive opportunities, including certain discretionary investments and potential financing alternatives.
REIT related ownership limitations and transfer restrictions may prevent or restrict certain transfers of our capital stock.
The impact of COVID-19 and related risks could materially affect our financial position, results of operations and cash flows.
Should one or more of these or other risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those expected. More information about potential risk factors which could affect our results is included in our filings with the SEC. Our filings with the SEC are available through the SEC website at www.sec.gov or through our investor relations website at investor.crowncastle.com. We use our investor relations website to disclose information about us that may be deemed to be material. We encourage investors, the media and others interested in us to visit our investor relations website from time to time to review up-to-date information or to sign up for e-mail alerts to be notified when new or updated information is posted on the site.
As used in this release, the term "including," and any variation thereof, means "including without limitation."

COMPANY PROFILE
Crown Castle International Corp. (to which the terms "Crown Castle," "CCIC," "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"), and (2) approximately 80,000 route miles of fiber primarily supporting small cell networks ("small cells") and fiber solutions. We refer to our towers, fiber and small cells 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 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.

OVERVIEW
 FINANCIALS & METRICSASSET PORTFOLIO OVERVIEWCAPITALIZATION OVERVIEWAPPENDIX
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 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 and installation services within our Towers segment.

DEFINITIONS
Non-GAAP Financial Measures, Segment Measures and Other Calculations
This Supplement includes presentations of Income (loss) from continuing operations (as adjusted), including per share—diluted amounts, Adjusted EBITDA, Adjusted Funds from Operations ("AFFO"), including per share amounts, Funds from Operations ("FFO"), including per share amounts, and Organic Contribution to Site Rental Revenues, 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 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:
Income (loss) from continuing operations (as adjusted), including per share—diluted amounts, is useful to investors and other interested parties in evaluating our financial performance. Management believes that this measure is meaningful to investors as it adjusts Income (loss) from continuing operations to exclude the impact of the Nontypical Items (as defined in this Supplemental Information Package and described further in our press release dated January 27, 2021), which management believes are unusual (including with respect to magnitude), infrequent and not reasonably likely to recur in the near term, to provide further insight into our results of operations and underlying trends and projections. Management also believes that identifying the impact of Nontypical Items as adjustments provides more transparency and comparability across periods. There can be no assurances that such items will not recur in future periods. Income (loss) from continuing operations (as adjusted), including per share—diluted amounts should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance.
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. Separately, we are also disclosing Adjusted EBITDA as adjusted to exclude the impact of Nontypical Items, which management believes are unusual (including with respect to magnitude), infrequent and not reasonably likely to recur in the near term, to provide further insight into our results of operations and underlying trends and projections. Management also believes that identifying the impact of Nontypical Items as adjustments provides increased transparency and comparability across periods. There can be no assurances that such items will not recur in future periods. Adjusted EBITDA (including as further adjusted to exclude Nontypical Items) should be considered only as a supplement to net income 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 (a) asset base (primarily depreciation, amortization and accretion) and (b) 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 revenue or expense is 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. Separately, we are also disclosing AFFO as adjusted to exclude the impact of Nontypical Items, which management believes are unusual (including with respect to magnitude), infrequent and not reasonably likely to recur in the near term, to provide further insight into our results of operations and underlying trends and projections. Management also believes that identifying the impact of Nontypical Items as adjustments provides increased transparency and comparability across periods. There can be no assurances that such items will not recur in future periods. AFFO (including as further adjusted to exclude Nontypical Items) should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flows 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 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 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 Revenues 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 the Organic Contribution to Site Rental Revenues to assess year-over-year growth rates for our rental activities, to evaluate current performance, to capture trends in rental rates, new leasing activities and tenant non-renewals in our core business, as well to forecast future results. Organic Contribution to Site Rental Revenues 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.
Consolidated Return on Invested Capital and Segment Cash Yield 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 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.
We define our non-GAAP financial measures, segment measures and other calculations as follows:
Non-GAAP Financial Measures
Income (loss) from continuing operations (as adjusted). We define Income (loss) from continuing operations (as adjusted) as Income (loss) from continuing operations less other operating income resulting from the Nontypical Items, plus incremental operating expenses and asset write-downs as a result of the Nontypical Items.
Income (loss) from continuing operations (as adjusted) per share—diluted. We define Income (loss) from continuing operations (as adjusted) per sharediluted as Income (loss) from continuing operations (as adjusted), divided by diluted weighted-average common shares outstanding.
Adjusted EBITDA. We define Adjusted EBITDA as Income (loss) from continuing operations 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, (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, cumulative effect of a change in accounting principle and stock-based compensation expense. Separately, Adjusted EBITDA, as adjusted to exclude the impact of Nontypical Items, reflects Adjusted EBITDA, less other operating income resulting from the Nontypical Items, plus incremental operating expenses as a result of the Nontypical Items.
Adjusted Funds from Operations. We define Adjusted Funds from Operations as FFO before straight-lined revenue, straight-lined expense, stock-based compensation expense, 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), cumulative effect of a change in accounting principle and adjustments for noncontrolling interests, less sustaining capital expenditures. Separately, Adjusted Funds from Operations, as adjusted to exclude the impact of Nontypical Items, reflects Adjusted Funds from Operations, less other operating income resulting from the Nontypical Items, plus incremental operating expenses as a result of the Nontypical Items.
AFFO per share. We define AFFO per share as AFFO, including as adjusted to exclude the impact of Nontypical Items, divided by diluted weighted-average common shares outstanding.
Funds from Operations. We define Funds from Operations as Income (loss) from continuing operations 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 CCIC common stockholders.
FFO per share. We define FFO per share as FFO divided by the diluted weighted-average common shares outstanding.
Organic Contribution to Site Rental Revenues. We define the Organic Contribution to Site Rental Revenues as the sum of the change in GAAP site rental revenues related to (1) new leasing activity, including revenues from the construction of small cells and the impact of prepaid rent, (2) escalators and less (3) non-renewals of tenant contracts.
Consolidated Invested Capital. We define Consolidated Invested Capital as gross investment in 1) property and equipment (excluding construction in process), 2) site rental contracts and tenant relationships, and 3) goodwill.
Consolidated Return on Invested Capital. We define Return on Invested Capital as Adjusted EBITDA less cash taxes divided by Consolidated Invested Capital.
Segment Net Invested Capital. We define Segment Net Invested Capital as gross 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 customers (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 Measures
Segment Site Rental Gross Margin. We define Segment Site Rental Gross Margin as segment site rental revenues less segment site rental cost of operations, excluding stock-based compensation expense and prepaid lease purchase price adjustments recorded in consolidated site rental cost of operations.
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 cost of operations, excluding stock-based compensation expense recorded in consolidated services and other cost of operations.
Segment Operating Profit. We define Segment Operating Profit as segment site rental gross margin plus segment services and other gross margin, and segment other operating (income) expense, less selling, general and administrative expenses attributable to the respective segment.
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 Calculations
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 either discretionary or integration 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.
The tables set forth on the following pages reconcile certain non-GAAP financial measures used herein to comparable GAAP financial measures. The components in these tables may not sum to the total due to rounding.
