"In the first quarter, we delivered solid results that exceeded our expectations and reflect a robust 5G leasing environment, positioning us to generate an expected double-digit growth in both AFFO per share and dividends per share for full year 2021," stated Jay Brown, Crown Castle’s Chief Executive Officer. "We are excited to continue to support our customers' wireless infrastructure needs as they deploy nationwide 5G in the U.S., and we expect to once again generate industry leading domestic tower revenue growth in 2021. We believe our unique portfolio of tower, small cell and fiber assets positions us to benefit from what we expect will be a decade-long investment cycle as our customers develop next-generation wireless networks. As a result, we expect the deployment of 5G in the U.S. to extend our opportunity to create long-term value for our shareholders while delivering dividend per share long-term growth of 7% to 8% per year.

"We believe our ability to offer towers, small cells and fiber solutions, which are all integral components of communications networks and are shared among multiple tenants, provides us the best opportunity to generate significant growth while delivering high returns for our shareholders. Based on the expected growth in data traffic and wireless carrier network investment, we believe the U.S. represents the highest growth and lowest risk market in the world for communications infrastructure ownership, and we are pursuing that opportunity with our comprehensive offering."

HIGHLIGHTS FROM THE QUARTER

• Site rental revenues. Site rental revenues grew 5%, or $59 million, from first quarter 2020 to first quarter 2021, inclusive of approximately $82 million in Organic Contribution to Site Rental Revenues and a $24 million decrease in straight-lined revenues. The $82 million in Organic Contribution to Site Rental Revenues represents approximately 6.3% growth, comprised of approximately 9.4% growth from new leasing activity and contracted tenant escalations, net of approximately 3.1% from tenant non-renewals.
• Net income. Net income for the first quarter 2021 was $121 million compared to $185 million for the first quarter 2020 and was impacted by a $143 million loss on the retirement of long-term obligations due to first quarter 2021 refinancing activities.
• AFFO per share. AFFO per share for the first quarter 2021 was $1.71, representing 20% growth when compared to $1.42 for the first quarter 2020.
• Capital Expenditures. Capital expenditures during the quarter were $302 million, comprised of $17 million of sustaining capital expenditures and $285 million of discretionary capital expenditures. Discretionary capital expenditures during the quarter primarily included approximately $225 million attributable to Fiber and approximately $49 million attributable to Towers.
• Common stock dividend. During the quarter, Crown Castle paid common stock dividends of approximately $588 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. During the quarter, Crown Castle issued $3.25 billion in aggregate principal amount of senior unsecured notes with a combination of 5-year, 10-year and 20-year maturities, resulting in a weighted average maturity and coupon of 12 years and approximately 2.1%, respectively. Net proceeds from the offering were used to redeem all of the outstanding 5.25% Senior Notes, repay a portion of outstanding borrowings under the 2016 Term Loan A, and repay a portion of the outstanding commercial paper notes at their maturity date.

"We are excited about the increasing level of activity we see in our business as our customers have begun to deploy 5G at scale," stated Dan Schlanger, Crown Castle's Chief Financial Officer. "We believe we are well positioned to support our growing number of 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. Looking forward, we believe we are in a great position to deliver on our long-term annual dividend growth target of 7% to 8% while at the same time making significant investments in our business that we believe will generate attractive long-term returns and support future growth. To help fund that growth, we were able to opportunistically access the bond market during the first quarter to refinance upcoming maturities, extending our maturity profile and reducing our overall cost of capital. We continue to take steps to complement our compelling total return opportunity with a lower risk profile, and we expect to have sufficient capacity to once again fund our discretionary investments this year with free cash flow and incremental borrowings."

• The increase to the midpoint of the full year 2021 Outlook for site rental revenues, adjusted EBITDA, and AFFO primarily reflect: 1) $140 million of additional straight-lined revenues associated with a long-term tower leasing agreement with Verizon that became effective April 1, 2021 and also resulted in an increase of the average contracted lease term under our existing Verizon tower site leases to approximately 10 years; 2) a $25 million increase in the expected services contribution; and 3) a $30 million decrease in expected interest expense, offset by $15 million of additional labor related costs associated with higher Towers activity than previously expected.
  
  
• The chart below reconciles the components of expected growth in site rental revenues from 2020 to 2021 of $355 million to $400 million, inclusive of expected Organic Contribution to Site Rental Revenues during 2021 of $295 million to $335 million, or approximately 6%, which is unchanged from our previously provided 2021 Outlook.

Non-GAAP Financial Measures, Segment Measures and Other Calculations

This press release includes presentations of Net income (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"). Our definition of FFO is consistent with guidelines from the National Association of Real Estate Investment Trusts.

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:

• Net Income (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 net income 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. Net income (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

Net Income (as adjusted). We define Net Income (as adjusted) as net income (loss) less other operating income resulting from the Nontypical Items, plus incremental operating expenses and asset write-downs as a result of the Nontypical Items.

Net Income (as adjusted) per share—diluted. We define net income (as adjusted) per share—diluted as Net Income (as adjusted), divided by diluted weighted-average common shares outstanding.

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, (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, (income) loss from discontinued operations 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, (income) loss from discontinued operations 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 net income 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.

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 the 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.

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, 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) our customers' investment, including investment cycles and the timing thereof, in network improvements (including 5G), the trends driving such investment and opportunities and demand for our assets 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, (13) tenant non-renewals, including the impact and timing thereof, (14) capital expenditures, including sustaining and discretionary capital expenditures, the timing thereof and any efficiencies that may result therefrom, and the discretionary capital budget and the funding (including capacity to fund) thereof, (15) straight-line adjustments, (16) revenues and growth thereof and benefits derived therefrom, (17) the recurrence of Nontypical Items, (18) net income (loss) (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) 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 and labor related costs, (26) our growing number of customers, (27) benefits stemming from our recent tower leasing agreement with Verizon, (28) the utility of certain financial measures, including non-GAAP financial measures and (29) the strength of the U.S. market for communications infrastructure ownership. 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."
