NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS-Unaudited

(Tabular dollars in millions, except per share amounts)

1. General

The information contained in the following notes to the condensed consolidated financial statements is condensed from that which would appear in the annual consolidated financial statements; accordingly, the condensed consolidated financial statements included herein should be reviewed in conjunction with the consolidated financial statements for the fiscal year ended December 31, 2019, and related notes thereto, included in the 2019 Form 10-K filed by Crown Castle International Corp. ("CCIC") with the SEC. Capitalized terms used but not defined in these notes to the condensed consolidated financial statements have the same meaning given to them in the 2019 Form 10-K. References to the "Company" refer to CCIC and its predecessor, as applicable, and their subsidiaries, unless otherwise indicated or the context indicates otherwise. As used herein, the term "including," and any variation thereof means "including without limitation." The use of the word "or" herein is not exclusive. Unless the context suggests otherwise, references to "U.S." are to the United States of America and Puerto Rico, collectively.

The Company owns, operates and leases shared communications infrastructure that is geographically dispersed throughout the U.S., including (1) towers and other structures, such as rooftops (collectively, "towers"), and (2) fiber primarily supporting small cell networks ("small cells") and fiber solutions. The Company's towers, fiber and small cells assets are collectively referred to herein as "communications infrastructure," and the Company's customers on its communications infrastructure are referred to herein as "tenants."

The Company's core business is providing access, including space or capacity, to its shared communications infrastructure via long-term contracts in various forms, including lease, license, sublease and service agreements (collectively, " tenant contracts").

The Company's operating segments consist of (1) Towers and (2) Fiber. See note 11.

As part of the Company's effort to provide comprehensive communications infrastructure solutions, as an ancillary business, the Company also offers certain services primarily relating to its Towers segment, predominately consisting of (1) site development services primarily relating to existing or new tenant equipment installations, including: site acquisition, architectural and engineering, or zoning and permitting (collectively, "site development services") and (2) tenant equipment installation or subsequent augmentations (collectively, "installation services").

The Company operates as a REIT for U.S. federal income tax purposes. In addition, the Company has certain taxable REIT subsidiaries ("TRSs"). See note 7.

Approximately 53% of the Company's towers are leased or subleased or operated and managed under master leases, subleases, and other agreements with AT&T, Sprint and T-Mobile. The Company has the option to purchase these towers at the end of their respective lease terms. The Company has no obligation to exercise such purchase options.

Basis of Presentation

The condensed consolidated financial statements included herein are unaudited; however, they include all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to state fairly the consolidated financial position of the Company at March 31, 2020, the condensed consolidated results of operations for the three months ended March 31, 2020 and 2019, and the condensed consolidated cash flows for the three months ended March 31, 2020 and 2019. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

2. Restatement of Previously Issued Condensed Consolidated Financial Statements

The following tables summarize the impact of the restatement adjustments that were related to the timing of revenue recognition on its tower installation services. Specifically, the Company determined that its historical practice of recognizing the full transaction price as service revenues upon completion of an installation was not acceptable under GAAP. Instead, a portion of the transaction price for the Company's tower installation services, specifically the amounts associated with permanent improvements recorded as fixed assets, represent a lease component and should be recognized as site rental revenues on a ratable basis over the associated estimated lease term. In addition, the Company has also made other adjustments to the financial statements referenced above to correct errors that were not material to its condensed consolidated financial statements. Such immaterial adjustments are related to a revision in the presentation of certain tower installation activities from a gross basis to a net basis, including the associated removal of certain amounts historically categorized as capital expenditures.  These immaterial adjustments relate exclusively to the Company's Towers segment. Collectively, the restatement adjustments and other immaterial adjustments are referred to herein as "Historical Adjustments."

In addition to the restatement of the condensed consolidated financial statements, certain historical information in the notes to the condensed consolidated financial statements have been restated to reflect the impact of the Historical Adjustments.

4. Revenues

Site rental revenues

The Company generates site rental revenues from its core business by providing tenants with access, including space or capacity, to its shared communications infrastructure via long-term tenant contracts in various forms, including lease, license, sublease and service agreements. Providing such access over the length of the tenant contract term represents the Company’s sole performance obligation under its tenant contracts.

Site rental revenues from the Company's tenant contracts are recognized on a straight-line, ratable basis over the fixed, non-cancelable term of the relevant tenant contract, which generally ranges from five to 15 years for wireless tenants and three to 20 years for the Company's fiber solutions tenants (including from organizations with high-bandwidth and multi-location demands), regardless of whether the payments from the tenant are received in equal monthly amounts during the life of the tenant contract. Certain of the Company's tenant contracts contain (1) fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the CPI), (2) multiple renewal periods exercisable at the tenant's option and (3) only limited termination rights at the applicable tenant's option through the current term. If the payment terms call for fixed escalations, upfront payments, or rent-free periods, the revenue is recognized on a straight-line basis over the fixed, non-cancelable term of the agreement. When calculating straight-line rental revenues, the Company considers all fixed elements of tenant contractual escalation provisions, even if such escalation provisions contain a variable element in addition to a minimum. The Company's assets related to straight-line site rental revenues include current amounts of $123 million included in "Other current assets" and non-current amounts of $1.4 billion included in "Deferred site rental receivables" as of March 31, 2020. Amounts billed or received prior to being earned are deferred and reflected in "Deferred revenues" and "Other long-term liabilities." Amounts to which the Company has an unconditional right to payment, which are related to both satisfied or partially satisfied performance obligations, are recorded within "Receivables, net" on the Company's condensed consolidated balance sheet.

Services and other revenues

As part of the Company’s effort to provide comprehensive communications infrastructure solutions, as an ancillary business, the Company offers certain services primarily relating to its Towers segment, predominately consisting of (1) site development services and (2) installation services. Upon contract commencement, the Company assesses its services to tenants and identifies performance obligations for each promise to provide a distinct service.

The Company may have multiple performance obligations for site development services, which primarily include: structural analysis, zoning, permitting and construction drawings. For each of the above performance obligations, services revenues are recognized at completion of the applicable performance obligation, which represents the point at which the Company believes it has transferred goods or services to the tenant. The revenue recognized is based on an allocation of the transaction price among the performance obligations in a respective contract based on estimated standalone selling price. The volume and mix of site development services may vary among contracts and may include a combination of some or all of the above performance obligations. Payments generally are due within 45 to 60 days and generally do not contain variable-consideration provisions. The transaction price for the Company's tower installation services consists of amounts for (1) permanent improvements to the Company's towers that represent a lease component and (2) the performance of the service. Amounts under the Company's tower installation service agreements that represent a lease component are recognized as site rental revenues on a straight-line basis over the length of the associated estimated lease term. For the performance of the installation service, the Company has one performance obligation, which is satisfied at the time of the applicable installation or augmentation and recognized as services and other revenues. Since performance obligations are typically satisfied prior to receiving payment from tenants, the unconditional right to payment is

recorded within "Receivables, net" on the Company’s condensed consolidated balance sheet. The vast majority of the Company’s services generally have a duration of one year or less.

Additional information on revenues

The following additional information on revenues reflect the impact of the Historical Adjustments, where applicable, as discussed in note 2. As of January 1, 2020 and March 31, 2020, $2.9 billion and $2.8 billion, respectively, of unrecognized revenue was reported in "Deferred revenues" and "Other long-term liabilities" on our condensed consolidated balance sheet. During the three months ended March 31, 2020, approximately $160 million of the January 1, 2020 unrecognized revenue balance was recognized as revenue. During the three months ended March 31, 2019, approximately $135 million of the January 1, 2019 unrecognized revenue balance was recognized as revenue.

The following table is a summary of the non-cancelable contracted amounts owed to the Company by tenants pursuant to tenant contracts in effect as of March 31, 2020.

	Nine Months Ending December 31,		Years Ending December 31,

(f) Notes under the CP Program may be issued, repaid and re-issued from time to time, with an aggregate principal amount of Commercial Paper Notes outstanding under the CP Program at any time not to exceed $1.0 billion. The net proceeds of the Commercial Paper Notes are expected to be used for general corporate purposes. The maturities of the 2019 Commercial Paper Notes, when outstanding, may vary but may not exceed 397 days from the date of issue. The Commercial Paper Notes are issued under customary terms in the commercial paper market and are issued at a discount from par or, alternatively, can be issued at par and bear varying interest rates on a fixed or floating basis. As of March 31, 2020, there were no outstanding Commercial Paper Notes. At any point in time, the Company intends to maintain available commitments under its 2016 Revolver in an amount at least equal to the amount of Commercial Paper Notes outstanding. While any outstanding commercial paper issuances generally have short-term maturities, the Company classifies the outstanding issuances, when applicable, as long-term based on its ability and intent to refinance the outstanding issuances on a long-term basis.

The following are the scheduled principal payments and final maturities of the total debt and other long-term obligations of the Company outstanding as of March 31, 2020, which do not consider the principal payments that will commence following the anticipated repayment dates on the Tower Revenue Notes.

Liabilities:
Total debt and other obligations	2	18,695		19,175		18,121		19,170

The fair value of cash and cash equivalents and restricted cash approximate the carrying value. The Company determines the fair value of its debt securities based on indicative, non-binding quotes from brokers. Quotes from brokers require judgment and are based on the brokers' interpretation of market information, including implied credit spreads for similar borrowings on recent trades or bid/ask prices or quotes from active markets if available. Since December 31, 2019, there have been no changes in the Company's valuation techniques used to measure fair values.

7. Income Taxes

The Company operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally entitled to a deduction for dividends that it pays and therefore is not subject to U.S. federal corporate income tax on its net taxable income that is currently distributed to its stockholders. The Company also may be subject to certain federal, state, local and foreign taxes on its income and assets, including (1) taxes on any undistributed income, (2) taxes related to the TRSs, (3) franchise taxes, (4) property taxes, and (5) transfer taxes. In addition, the Company could in certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Internal Revenue Code of 1986, as amended, to maintain qualification for taxation as a REIT.

The Company's TRS assets and operations will continue to be subject, as applicable, to federal and state corporate income taxes or to foreign taxes in the jurisdictions in which such assets and operations are located. The Company's foreign assets and operations (including its tower operations in Puerto Rico) are subject to foreign income taxes in the jurisdictions in which such assets and operations are located, regardless of whether they are included in a TRS or not.

For the three months ended March 31, 2020 and 2019, the Company's effective tax rate differed from the federal statutory rate predominately due to the Company's REIT status, including the dividends paid deduction.

8. Per Share Information

Basic net income (loss) attributable to CCIC common stockholders, per common share, excludes dilution and is computed by dividing net income (loss) attributable to CCIC common stockholders by the weighted-average number of common shares outstanding during the period. For the three months ended March 31, 2020 and 2019, diluted net income (loss) attributable to CCIC common stockholders, per common share, is computed by dividing net income (loss) attributable to CCIC common stockholders by the weighted-average number of common shares outstanding during the period, plus any potential dilutive common share equivalents, including shares issuable upon (1) the vesting of restricted stock units as determined under the treasury stock method and (2) conversion of the Company's 6.875% Mandatory Convertible Preferred Stock, as determined under the if-converted method. The table below also gives effect to the Historical Adjustments, as described in note 2.

	Three Months Ended March 31,
	2020			2019
				(As Restated)
Net income (loss) attributable to CCIC stockholders	$	185		$	193
Dividends on preferred stock	(28		)	(28		)
Net income (loss) attributable to CCIC common stockholders for basic and diluted computations	$	157		$	165
Weighted-average number of common shares outstanding (in millions):
Basic weighted-average number of common stock outstanding	416			415
Effect of assumed dilution from potential issuance of common shares relating to restricted stock units	2			2
Diluted weighted-average number of common shares outstanding	418			417
Net income (loss) attributable to CCIC common stockholders, per common share:
Basic	$	0.38		$	0.40
Diluted	$	0.38		$	0.40
Dividends/distributions declared per share of common stock	$	1.20		$	1.125
Dividends/distributions declared per share of preferred stock	$	17.1875		$	17.1875

During the three months ended March 31, 2020, the Company granted one million restricted stock units. For the three months ended March 31, 2020, 15 million common share equivalents related to the 6.875% Mandatory Convertible Preferred Stock were excluded from the dilutive common shares because the impact of such conversion would be anti-dilutive, based on the Company's common stock price as of March 31, 2020.

9. Commitments and Contingencies

The Company is involved in various claims, lawsuits or proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs or losses that may be incurred, if any, management believes the resolution of such uncertainties and the incurrence of such costs should not have a material adverse effect on the Company's condensed consolidated financial position or results of operations. Additionally, the Company and certain of its subsidiaries are contingently liable for commitments or performance guarantees arising in the ordinary course of business, including certain letters of credit or surety bonds. In addition, see note 1 for a discussion of the Company's option to purchase approximately 53% of its towers at the end of their respective lease terms. The Company has no obligation to exercise such purchase options.

SEC Investigation

In September 2019, the Company received a subpoena from the SEC requesting certain documents from 2015 through the present, primarily related to the Company's long-standing capitalization and expense policies for tenant upgrades and installations in its services business. Prior to receiving this subpoena, the Company previously provided information to the SEC related to certain services-related transactions. The Company is cooperating fully with the SEC's investigation and cannot predict the ultimate timing, scope or outcome of this matter.

Shareholder Litigation

In February and March 2020, putative securities class action suits were filed in the United States District Court for the District of New Jersey against the Company and certain of its current officers. The lawsuits were filed on behalf of investors that purchased or otherwise acquired stock of the Company between February 26, 2018 and February 26, 2020. The allegations relate to allegedly false or misleading statements or other failures to disclose information about the Company's business, operations and prospects. The complaints seek unspecified money damages and the award of plaintiffs' costs and expenses incurred in the respective class action. The Company is currently unable to determine the likelihood of an outcome or estimate a range of reasonably possible losses, if any, with respect to these lawsuits. The Company believes these lawsuits are without merit and intends to defend itself vigorously.

In April 2020, a stockholder derivative lawsuit was filed by Melvyn Klein in the United States District Court for the District of Delaware, against the Company, as a nominal defendant, and its current directors and certain of its current officers. The complaint alleges, among other things, breaches of fiduciary duties, waste of corporate assets, unjust enrichment, and false or misleading statements, between February 27, 2018 through the present. The complaint seeks, among other things, unspecified money damages, costs and expenses, restitution from the defendants, and an order requiring the Company to implement certain corporate governance reforms. As a nominal defendant, no monetary relief is sought against the Company itself.

10. Equity

Declaration and Payment of Dividends

During the three months ended March 31, 2020, the following dividends/distributions were declared or paid:

Equity Type	Declaration Date	Record Date	Payment Date	Dividends Per Share		Aggregate Payment Amount
Common Stock	February 20, 2020	March 13, 2020	March 31, 2020	$	1.20	$	504	(a)
6.875% Mandatory Convertible Preferred Stock	December 9, 2019	January 15, 2020	February 3, 2020	$	17.1875	$	28
6.875% Mandatory Convertible Preferred Stock	March 12, 2020	April 15, 2020	May 1, 2020	$	17.1875	$	28

(a) Inclusive of dividends accrued for holders of unvested restricted stock units, which will be paid when and if the restricted stock units vest.

Purchases of the Company's Common Stock

For the three months ended March 31, 2020, the Company purchased 0.4 million shares of its common stock utilizing $73 million in cash. The shares of common stock purchased relate to shares withheld in connection with the payment of withholding taxes upon vesting of restricted stock units.

2018 "At-the-Market" Stock Offering Program

In April 2018, the Company established an "at-the-market" stock offering program through which it may issue and sell shares of its common stock having an aggregate gross sales price of up to $750 million ("2018 ATM Program"). Sales under the 2018 ATM Program may be made by means of ordinary brokers' transactions on the NYSE or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or, subject to our specific instructions, at negotiated prices. The Company intends to use the net proceeds from any sales under the 2018 ATM Program for general corporate purposes, which may include (1) the funding of future acquisitions or investments or (2) the repayment or repurchase of any outstanding indebtedness. The Company has not sold any shares of common stock under the 2018 ATM Program.

11. Operating Segments

The Company's operating segments consist of (1) Towers and (2) Fiber. The Towers segment provides access, including space or capacity, to the Company's approximately 40,000 towers geographically dispersed throughout the U.S. The Towers segment also reflects certain ancillary services relating to the Company's towers, predominately consisting of site development services and installation services. The Fiber segment provides access, including space or capacity, to the Company's approximately 80,000 route miles of fiber primarily supporting small cell networks and fiber solutions geographically dispersed throughout the U.S.

The measurements of profit or loss used by the Company's chief operating decision maker ("CODM") to evaluate the performance of its operating segments are (1) segment site rental gross margin, (2) segment services and other gross margin and (3) segment operating profit. The Company defines segment site rental gross margin as segment site rental revenues less segment site rental cost of operations, which excludes stock-based compensation expense and prepaid lease purchase price adjustments recorded in consolidated cost of operations. The Company defines segment services and other gross margin as segment services and other revenues less segment services and other cost of operations, which excludes stock-based compensation expense recorded in consolidated cost of operations. The Company defines segment operating profit as segment site rental gross margin plus segment services and other gross margin, 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.

The following table set forth the Company's segment operating results for the three months ended March 31, 2020 and 2019. Costs that are directly attributable to Towers and Fiber are assigned to those respective segments. Additionally, certain costs are shared across segments and are reflected in the Company's segment measures through allocations that management believes to be reasonable. The "Other" column (1) represents amounts excluded from specific segments, such as 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, interest income, other income (expense), income (loss) from discontinued operations, and stock-based compensation expense, and (2) reconciles segment operating profit to income (loss) before income taxes, as the amounts are not utilized in assessing each segment’s performance. The "Other" total assets balance includes corporate assets such as cash and cash equivalents which have not been allocated to specific segments. There are no significant revenues resulting from transactions between the Company's operating segments.

The table below also gives effect to the Historical Adjustments, as described in note 2. Each of the Historical Adjustments for the three months ended March 31, 2019 are attributable only to the Towers segment.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the response to Part I, Item 1 of this report and the consolidated financial statements of the Company including the related notes and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" ("MD&A") included in the 2019 Form 10-K. As discussed in the "Explanatory Note" to this Form 10-Q and in further detail in the 2019 Form 10-K, amounts reflected for the first quarter of 2019 have been restated to reflect the impact of the Historical Adjustments.

General Overview

Overview

We own, operate and lease shared communications infrastructure that is geographically dispersed throughout the U.S., including approximately (1) 40,000 towers and (2) 80,000 route miles of fiber primarily supporting small cells and fiber solutions.

Our towers have a significant presence in the top 100 basic trading areas ("BTAs"), and the majority of our small cells and fiber is located in major metropolitan areas. Site rental revenues represented 92% of our first quarter 2020 consolidated net revenues. Our Towers segment and Fiber segment accounted for 66% and 34%, respectively, of our first quarter 2020 site rental revenues. See note 11 to our condensed consolidated financial statements. The vast majority of our site rental revenues is of a recurring nature and is subject to long-term tenant contracts with our tenants.

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;

19

◦ 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 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.

Business Fundamentals and Results

The following are certain highlights of our business fundamentals and results as of the three months ended March 31, 2020.

• We operate as a REIT for U.S. federal income tax purposes

◦ As a REIT, we are generally entitled to a deduction for dividends that we pay and therefore are not subject to U.S. federal corporate income tax on our taxable income that is distributed to our stockholders.

◦ To remain qualified and taxed as a REIT, we will generally be required to annually distribute to our stockholders at least 90% of our REIT taxable income, after the utilization of our NOLs (determined without regard to the dividends paid deduction and excluding net capital gain).

◦ See note 7 to our condensed consolidated financial statements for further discussion of our REIT status.

• Potential growth resulting from the increasing demand for data

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

◦ We expect U.S. wireless carriers will continue to focus on improving network quality and expanding capacity (including through 5G initiatives) by utilizing a combination of towers and small cells. We believe our product offerings of towers and small cells provide a comprehensive solution to our wireless tenants' growing communications infrastructure needs.

◦ We expect organizations will continue to increase the usage of high-bandwidth applications that will require the utilization of more fiber infrastructure and fiber solutions, such as those we provide.

◦ Within our Fiber segment, we are able to generate growth and returns for our stockholders by deploying our fiber for both small cells and fiber solutions tenants.

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

• Substantially all of our communications infrastructure can accommodate additional tenancy, either as currently constructed or with appropriate modifications.

• Investing capital efficiently to grow long-term dividends per share (see also "Item 2. MD&A—General Overview—Strategy")

◦ Discretionary capital expenditures of $426 million for the three months ended March 31, 2020, predominately resulting from the construction of new communications infrastructure and improvements to existing communications infrastructure in order to support additional tenants.

◦ We expect to continue to construct and acquire new communications infrastructure based on our tenants' needs and generate attractive long-term returns by adding additional tenants over time.

• Site rental revenues under long-term tenant contracts

◦ Initial terms of five to 15 years for site rental revenues derived from wireless tenants, with contractual escalations and multiple renewal periods, at the option of the tenant, of five to 10 years each.

◦ Initial terms that generally vary between three to 20 years for site rental revenues derived from our fiber solutions tenants (including from organizations with high-bandwidth and multi-location demands).

◦ Weighted-average remaining term of approximately five years, exclusive of renewals exercisable at the tenants' option, currently representing approximately $24 billion of expected future cash inflows.

• Majority of our revenues from large wireless carriers

◦ 74% of our site rental revenues were derived from T-Mobile, AT&T, Verizon Wireless and Sprint for the three months ended March 31, 2020.

20

▪ On April 1, 2020, T-Mobile and Sprint announced the completion of their previously disclosed merger. For additional information, see "Item 1A. Risk Factors" in the 2019 Form 10-K.

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

◦ Approximately 90% of our Towers site rental gross margin and approximately 80% of our Towers site rental gross margin is derived from towers that reside on land that we own or control for greater than 10 and 20 years, respectively. The aforementioned percentages include towers that reside on land interests that are owned, including through fee interests and perpetual easements, which represent approximately 40% of our Towers site rental gross margin.

• Majority of our fiber assets are located in major metropolitan areas and are on public rights-of-way.

• Minimal sustaining capital expenditure requirements

◦ Sustaining capital expenditures represented approximately 1% of net revenues.

• Debt portfolio with long-dated maturities extended over multiple years, with the vast majority of such debt having a fixed rate (see "Item 3. Quantitative and Qualitative Disclosures About Market Risk" for a further discussion of our debt)

◦ As of March 31, 2020, after giving effect to our April 2020 Senior Notes issuance and the application of the net proceeds therefrom, our outstanding debt has a weighted-average interest rate of 3.7% and weighted-average maturity of approximately seven years (assuming anticipated repayment dates on our Tower Revenue Notes). See note 13 to our condensed consolidated financial statements.

◦ 88% of our debt has fixed rate coupons, after giving effect to our April 2020 Senior Notes issuance (see note 13 to our condensed consolidated financial statements).

◦ Our debt service coverage and leverage ratios are within their respective financial maintenance covenants.

• During 2020, we have completed the following financing transactions (see note 13 to our condensed consolidated financial statements)

◦ In April 2020, we issued $1.25 billion aggregate principal amount of senior unsecured notes ("April 2020 Senior Notes"), which consisted of (1) $750 million aggregate principal amount of 3.300% senior unsecured notes due July 2030 and (2) $500 million aggregate principal amount of 4.150% senior unsecured notes due July 2050. We used the net proceeds of the April 2020 Senior Notes offering to repay outstanding borrowings under the 2016 Revolver.

• Significant cash flows from operations

◦ Net cash provided by operating activities was $653 million for the three months ended March 31, 2020.

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

• Returning cash flows provided by operations to stockholders in the form of dividends

◦ During March 2020, we paid a common stock dividend of $1.20 per share, totaling approximately $513 million.

◦ We currently expect our common stock dividends over the next 12 months to be a cumulative amount of at least $4.80 per share, or an aggregate amount of approximately $2.0 billion.

◦ Over time, we expect to increase our dividend per share generally commensurate with our realized growth in cash flows. Any future common stock dividends are subject to declaration by our board of directors. See note 10 to our condensed consolidated financial statements for further information regarding our common stock and dividends.

◦ During February 2020, we paid a preferred stock dividend of $17.1875 per share, totaling approximately $28 million. We currently expect our preferred stock dividends, prior to the mandatory conversion of our 6.875% Mandatory Convertible Preferred Stock in August 2020, to be a cumulative amount of $17.1875 per share, or an aggregate amount of approximately $28 million. Any future preferred stock dividends are subject to declaration by our board directors.

Outlook Highlights

The following are certain highlights of our full year 2020 outlook that impact our business fundamentals described above.

• We expect that, when compared to full year 2019, our full year 2020 site rental revenue growth will be positively impacted by higher tenant additions, as large wireless carriers and fiber solutions tenants attempt to meet the increasing demand for data.

• We expect to continue to invest a meaningful amount of our available capital in the form of discretionary capital expenditures for 2020, as we continue to construct new small cells and fiber as a result of the anticipated returns on such discretionary investments. We also expect sustaining capital expenditures to remain approximately 2% of net revenues for full year 2020.

Coronavirus (COVID-19)

The global outbreak of the novel coronavirus (COVID-19) was declared a pandemic by the World Health Organization and a national emergency by the U.S. government in March 2020 and has adversely affected the United States. In response, both the public and private sectors have introduced certain policies and initiatives in an effort to reduce the transmission of COVID-19 ("Initiatives"), such as the imposition of travel restrictions; mandates from federal, state and local authorities to close non-essential businesses and avoid large gatherings of people; quarantine or "shelter-in-place;" and the promotion of social distancing and the adoption of work-from-home and online learning by companies and institutions. In addition, the continued spread of COVID-19 and the resulting Initiatives have led to a significant economic downturn, global supply chain disruptions and volatility in the global capital markets.

In accordance with the U.S. Department of Homeland Security guidance issued in March 2020 designating telecommunications infrastructure and networks as critical infrastructure, we have continued our operations to ensure viability of communications networks, which are essential to public health and safety. To date, we have taken a variety of measures to ensure the availability of our critical infrastructure, promote the health and safety of our employees, and support the communities in which we operate. These measures include providing support for our tenants as reflected in the FCC's "Keep Americans Connected" pledge, requiring work-from-home arrangements for a large portion of our workforce and imposing travel restrictions for our employees where practicable, canceling physical participation in meetings, events and conferences, and other modifications to our business practices. We will continue to actively monitor the situation and may take further actions as may be required by governmental authorities or that we determine are in the best interests of our employees, tenants, business partners and stockholders.

We do not believe that COVID-19 had a material impact on our financial position, results of operations and cash flows in the first quarter of 2020. Given the Company’s access to various sources of liquidity, we currently anticipate that we will be able to maintain sufficient liquidity as we manage through the current environment. See also "Item 2. MD&A—Liquidity and Capital Resources—Liquidity Position" and "Item 1A. Risk Factors."

Results of Operations

The following discussion of our results of operations should be read in conjunction with our condensed consolidated financial statements and the 2019 Form 10-K. Amounts for three months ended March 31, 2019, and any discussion relating to those amounts, give effect to the impact of the Historical Adjustments as described in the "Explanatory Note."

The following discussion of our results of operations is based on our condensed consolidated financial statements prepared in accordance with GAAP, which requires us to make estimates and judgments that affect the reported amounts (see "Item 2. MD&A—Accounting and Reporting Matters—Critical Accounting Policies and Estimates" and note 3 to our consolidated financial statements in the 2019 Form 10-K).

Our operating segments consist of (1) Towers and (2) Fiber. See note 11 to our condensed consolidated financial statements for further discussion of our operating segments.

Site rental revenues grew $68 million, or 5%, for the three months ended March 31, 2020 compared to the three months ended March 31, 2019. This growth was predominately comprised of the factors depicted in the chart below:

(In millions of dollars)

23

(a) As restated.

(b) Includes amortization of up-front payments received from long-term tenant contracts and other deferred credits (commonly referred to as prepaid rent).

(c) The components in this chart may not sum to the total due to rounding.

Towers site rental revenues for the first quarter of 2020 were $867 million and increased by $39 million, or 5%, from $828 million during the same period in the prior year. The increase in Towers site rental revenues was impacted by the following items, inclusive of straight-line accounting: tenant additions across our entire portfolio, renewals or extensions of tenant contracts, escalations and non-renewals of tenants contracts. Tenant additions were influenced by our tenants' ongoing efforts to improve network quality and capacity.

Fiber site rental revenues for the first quarter of 2020 were $443 million and increased by $29 million, or 7%, from $414 million during the same period in the prior year. The increase in Fiber site rental revenues was predominately impacted by the increased demand for small cells and fiber solutions. Increased demand for small cells was driven by our tenants' network strategy in an effort to provide capacity and relieve network congestion, and increased demand for fiber solutions was driven by increasing demand for data.

The increase in Towers site rental gross margin was related to the previously-mentioned 5% increase in Towers site rental revenues and relatively fixed costs to operate our towers. The increase in Fiber site rental gross margin was predominately related to the previously-mentioned 7% increase in Fiber site rental revenues.

Towers services and other gross margin was $13 million for the first quarter of 2020 and decreased by $29 million, or 69%, from $42 million during the same period in the prior year, which is a reflection of the volume of activity from carriers' network enhancements and the volume and mix of services and other work. Our services and other offerings are of a variable nature as these revenues are not under long-term contracts.

Towers operating profit for the first quarter of 2020 increased by $9 million, or 1%, from the same period in the prior year. The increase in Towers operating profit was primarily related to the growth in our Towers site rental revenues and relatively fixed costs to operate our towers and partially offset by the previously-mentioned decrease in Towers service activity.

Fiber operating profit for the first quarter of 2020 increased by $14 million, or 6%, from the same period in the prior year. Fiber operating profit was positively impacted by increased demand for small cells and fiber solutions and was partially offset by an increase in Fiber-related selling, general and administrative expenses.

Interest expense and amortization of deferred financing costs were $175 million for the first quarter of 2020 and increased by $7 million, or 4%, from $168 million during the same period in the prior year. The increase predominately resulted from a corresponding increase in our outstanding indebtedness due to the financing of our discretionary capital expenditures.

For the first quarter of 2020 and 2019, the effective tax rate differs from the federal statutory rate predominately due to our REIT status, including the dividends paid deduction.  See note 7 to our condensed consolidated financial statements and also note 11 to our consolidated financial statements in the 2019 Form 10-K.

Net income attributable to CCIC stockholders was $185 million during the first quarter of 2020 compared to $193 million during the first quarter of 2019. The decrease was predominately related to the impact from the aforementioned Towers service activity as well as an increase in selling, general and administrative expenses, partially offset by growth in our site rental activities in both our Towers and Fiber segments.

Adjusted EBITDA increased $10 million, or 1%, from the first quarter of 2019 to the first quarter of 2020, reflecting the growth in our site rental activities in both our Towers and Fiber segments, partially offset by the previously-mentioned decrease in Towers service activity.

Liquidity and Capital Resources

Overview

General. Our core business generates revenues under long-term tenant contracts (see "Item 2. MD&A—General Overview—Overview") from (1) the largest U.S. wireless carriers and (2) fiber solutions tenants. 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 portfolio of communications infrastructure, (2) returning a meaningful portion of our cash generated by operating activities to our stockholders in the form of dividends, and (3) investing capital efficiently to grow cash flows and

24

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.

We have engaged, and expect to continue to engage, in discretionary investments that we believe will maximize long-term stockholder value. Our historical discretionary investments include (in no particular order): constructing communications infrastructure, acquiring communications infrastructure, acquiring land interests (which primarily relate to land assets under towers), improving and structurally enhancing our existing communications infrastructure, purchasing shares of our common stock, and purchasing, repaying, or redeeming our debt. We have recently spent, and expect to continue to spend, a significant percentage of our discretionary investments on the construction of small cells and fiber. We seek to fund our discretionary investments with both net cash generated by operating activities and cash available from financing capacity, such as the use of our undrawn availability from the 2016 Revolver, issuances under our CP Program, debt financings and issuances of equity or equity-related securities, including under our 2018 ATM Program.

We seek to maintain a capital structure that we believe drives long-term stockholder value and optimizes our weighted-average cost of capital. We target a leverage ratio of approximately five times Adjusted EBITDA and interest coverage of Adjusted EBITDA to interest expense of approximately three times, subject to various factors, such as the availability and cost of capital and the potential long-term return on our discretionary investments. We may choose to increase or decrease our leverage or coverage from these targets for various periods of time. We have no significant contractual debt maturities until 2021 (other than principal payments on certain outstanding debt).

We operate as a REIT for U.S. federal income tax purposes. We expect to continue to pay minimal cash income taxes as a result of our REIT status and our NOLs. See note 7 to our condensed consolidated financial statements and the 2019 Form 10-K.

Liquidity Position. The following is a summary of our capitalization and liquidity position as of March 31, 2020, after giving effect to our April 2020 Senior Notes offering and the application of the net proceeds therefrom. See "Item 3. Quantitative and Qualitative Disclosures About Market Risk" and notes 5 and 13 to our condensed consolidated financial statements for additional information regarding our debt, as well as note 10 to our condensed consolidated financial statements for additional information regarding our 2018 ATM Program.

(b) Availability at any point in time is subject to certain restrictions based on the maintenance of financial covenants contained in the 2016 Credit Facility. See the 2019 Form 10-K. At any point in time, we intend to maintain available commitments under our 2016 Revolver in an amount at least equal to the amount of outstanding Commercial Paper Notes.

(c) See "Item 2. MD&A—General Overview—Overview" and note 5 to our condensed consolidated financial statements for further information regarding the CP Program.

Over the next 12 months:

• Our liquidity sources may include (1) cash on hand, (2) net cash generated by our operating activities, (3) undrawn availability under our 2016 Revolver, (4) issuances under our CP Program, and (5) issuances of equity pursuant to our 2018 ATM Program. Our liquidity uses over the next 12 months are expected to include (1) debt service obligations of $949 million (principal payments), (2) cumulative common stock dividend payments expected to be at least $4.80 per share, or an aggregate amount of approximately $2.0 billion (see "Item 2. MD&A—Business Fundamentals and Results"), (3) prior to the automatic conversion of our 6.875% Convertible Preferred Stock in August 2020, dividend payments related to such preferred stock of approximately $28 million and (4) capital expenditures. Additionally, amounts available under the CP Program may be repaid and re-issued from time to time. During the next 12 months, while our liquidity uses are expected to exceed our net cash provided by operating activities, we expect that our liquidity sources described above should be sufficient to cover our expected uses. Historically, from time to time, we have accessed the capital markets to issue debt and equity.

• See "Item 3. Quantitative and Qualitative Disclosures About Market Risk" for a tabular presentation of our debt maturities and a discussion of anticipated repayment dates.

Operating Activities

Net cash provided by operating activities of $653 million for the first three months of 2020 increased by $141 million, or 28%, compared to the first three months of 2019, due primarily to the growth in our core business and a net increase from changes in working capital. Changes in working capital contribute to variability in net cash provided by operating activities, largely due to the timing of advanced payments by us and advanced receipts from tenants. We expect to grow our net cash provided by operating activities in the future (exclusive of changes in working capital) if we realize expected growth in our core business.

Investing Activities

Net cash used for investing activities of $468 million for the first three months of 2020 decreased by $21 million, or 4%, from the first three months of 2019 as a result of a decrease in discretionary capital expenditures related to the construction of small cells and fiber.

Capital Expenditures

Our capital expenditures have been categorized as discretionary, sustaining or integration as described below.

• Discretionary capital expenditures are 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. The expansion or development of existing communications infrastructure to accommodate new leasing typically varies based on, among other factors: (1) the type of communications infrastructure, (2) the scope, volume, and mix of work performed on the communications infrastructure, (3) existing capacity prior to installation, or (4) changes in structural engineering regulations and standards. Currently, construction of new communications infrastructure is predominately comprised of the construction of small cells and fiber. Our decisions regarding discretionary capital expenditures are influenced by the availability and cost of capital and expected returns on alternative uses of cash, such as payments of dividends and investments.

• Integration capital expenditures consist of those capital expenditures made as a result of integrating acquired companies into our business.

• Sustaining capital expenditures consist of those capital expenditures not otherwise categorized as 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.

(a) As restated.

(b) Towers segment includes $42 million and $41 million of capital expenditures incurred during the three months ended March 31, 2020 and 2019, respectively, in connection with tenant installations and upgrades on our towers.

Discretionary capital expenditures were primarily impacted by the construction of small cells and fiber (including certain construction projects that may take 18 to 36 months to complete) to address our tenants' growing demand for data. See also "Item 2. MD&A—General Overview—Outlook Highlights" for our expectations surrounding 2020 capital expenditures.

Financing Activities. We seek to allocate cash generated by our operations in a manner that will enhance long-term stockholder value, which may include various financing activities such as (in no particular order): (1) paying dividends on our common stock (currently expected to total at least $4.80 per share over the next 12 months, or an aggregate amount of approximately $2.0 billion); (2) paying dividends on our 6.875% Convertible Preferred Stock (expected to total approximately $28 million, prior to the automatic conversion of such preferred stock in August 2020); (3) purchasing our common stock; or (4) purchasing, repaying, or redeeming our debt. See notes 5, 10 and 13 to our condensed consolidated financial statements.

Net cash used for financing activities of $50 million for the first three months of 2020 increased by $22 million, or 79%, from the first three months of 2019 as a result of the net impact from our common and preferred stock dividend payments, purchases of common stock and our issuances, purchases and repayments of debt (including with respect to our 2016 Revolver and CP Program). See Item 2. MD&A—General Overview—Business Fundamentals and Results and notes 5 and 10 to our condensed consolidated financial statements for further information.

In April 2020, we issued $1.25 billion aggregate principal amount of senior unsecured notes, the proceeds of which were used to repay outstanding indebtedness under the 2016 Revolver. See note 13 to our condensed consolidated financial statements.

Credit Facility.

The proceeds of our 2016 Revolver may be used for general corporate purposes, which may include the financing of capital expenditures, acquisitions and purchases of our common stock. As of April 29, 2020, there were no amounts outstanding and $5.0 billion in undrawn availability under our 2016 Revolver. See notes 5 and 13 to our condensed consolidated financial statements.

Commercial Paper Program. See "Item 2. MD&A—General Overview—Overview" and note 5 to our condensed consolidated financial statements for further information regarding our CP Program. As of April 29, 2020, there were no amounts outstanding under our CP Program.

Incurrence, Purchases, and Repayments of Debt. See Item 2. MD&A—General Overview—Business Fundamentals and Results and note 13 to our condensed consolidated financial statements for further discussion of our recent issuances, purchases and repayments of debt.

Common Stock Activity. See note 10 to our condensed consolidated financial statements for further information regarding our common stock and dividends. See below for a discussion of the anticipated automatic conversion of 6.875% Mandatory Convertible Preferred Stock.

27

Convertible Preferred Stock Activity. As of both March 31, 2020 and December 31, 2019, we had 2 million shares of 6.875% Mandatory Convertible Preferred Stock outstanding. Unless converted earlier, each outstanding share of the 6.875% Mandatory Convertible Preferred Stock will automatically convert into shares of our common stock on August 1, 2020. Currently, each share of the 6.875% Mandatory Convertible Preferred Stock will convert into between 8.7914 shares (based on the current maximum conversion price of $113.75) and 10.5496 shares (based on the current minimum conversion price of $94.79) of common stock, depending on the applicable market value of the common stock and subject to certain anti-dilution adjustments. At any time prior to August 1, 2020, holders of the 6.875% Mandatory Convertible Preferred Stock may elect to convert all or a portion of their shares into common stock at the minimum conversion rate of 8.7914 shares of common stock per share of 6.875% Mandatory Convertible Preferred Stock, subject to certain anti-dilution adjustments. See note 10 to our condensed consolidated financial statements for further discussion of the 6.875% Mandatory Convertible Preferred Stock dividends.

ATM Program. See note 10 to our condensed consolidated financial statements for further information regarding our 2018 ATM Program.

Debt Covenants. Our Credit Agreement contains financial maintenance covenants. We are currently in compliance with these financial maintenance covenants and, based upon our current expectations, we believe we will continue to comply with our financial maintenance covenants. In addition, certain of our debt agreements also contain restrictive covenants that place restrictions on us and may limit our ability to, among other things, incur additional debt and liens, purchase our securities, make capital expenditures, dispose of assets, undertake transactions with affiliates, make other investments, pay dividends or distribute excess cash flow. See the 2019 Form 10-K for a further discussion of our debt covenants, certain restrictive covenants and factors that are likely to determine our subsidiaries' ability to comply with current and future debt covenants.

Accounting and Reporting Matters

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are those that we believe (1) are most important to the portrayal of our financial condition and results of operations or (2) require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. In many cases, the accounting treatment of a particular transaction is specifically prescribed by GAAP. In other cases, management is required to exercise judgment in the application of accounting principles with respect to particular transactions. The critical accounting policies and estimates for 2020 are not intended to be a comprehensive list of our accounting policies and estimates. Our critical accounting policies and estimates as of December 31, 2019 are described in "Item 7. MD&A—Accounting and Reporting Matters" and in note 3 of our consolidated financial statements in the 2019 Form 10-K.

Non-GAAP and Segment Financial Measures

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

28

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. The reconciliation of Adjusted EBITDA to our net income (loss) is set forth below.

(In millions of dollars)	Three Months Ended March 31,
	2020			2019
				(As Restated)
Net income (loss)	$	185		$	193
Adjustments to increase (decrease) net income (loss):
Asset write-down charges	4			6
Acquisition and integration costs	5			4
Depreciation, amortization and accretion	399			394
Amortization of prepaid lease purchase price adjustments	5			5
Interest expense and amortization of deferred financing costs	175			168
(Gains) losses on retirement of long-term obligations	—			1
Interest income	(1		)	(2		)
Other (income) expense	—			1
(Benefit) provision for income taxes	5			6
Stock-based compensation expense	36			29
Adjusted EBITDA(a)(b)	$	814		$	804

(a) The components in this table may not sum to the total due to rounding.

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

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

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

• although specific definitions may vary, it is widely used by investors or other interested parties in evaluation of the 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;

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

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

Our management uses Adjusted EBITDA:

• as a performance goal in employee annual incentive compensation;

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

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

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

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

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

29

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

In addition to the non-GAAP measures used herein and as discussed in note 11 to our condensed consolidated financial statements, we also provide (1) segment site rental gross margin, (2) segment services and other gross margin, and (3) segment operating profit, which are key measures used by management to evaluate the performance of our operating segments. These segment measures are provided pursuant to GAAP requirements related to segment reporting.

We define segment site rental gross margin as segment site rental revenues less segment site rental cost of operations, which excludes stock-based compensation expense and prepaid lease purchase price adjustments recorded in consolidated site rental cost of operations. We define segment services and other gross margin as segment services and other revenues less segment services and other cost of operations, which excludes stock-based compensation expense recorded in consolidated services and other cost of operations. We define segment operating profit as segment site rental gross margin plus segment services and other gross margin, 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.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following section updates "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" in the 2019 Form 10-K and should be read in conjunction with that report as well as our condensed consolidated financial statements included in Part 1, Item 1 of this Quarterly Report on Form 10-Q.

Interest Rate Risk

Our interest rate risk relates primarily to the impact of interest rate movements on the following, after giving effect to our April 2020 Senior Notes offering and the application of the net proceeds therefrom:

• the potential refinancing of our existing debt ($18.7 billion outstanding at March 31, 2020 and $18.1 billion at December 31, 2019);

• our $2.3 billion and $3.0 billion of floating rate debt at March 31, 2020 and December 31, 2019, respectively, which represented approximately 12% and 17% of our total debt, as of March 31, 2020 and December 31, 2019, respectively; and

• potential future borrowings of incremental debt, including borrowings under our 2016 Credit Facility and issuances under the CP Program.

We currently have no interest rate swaps.

Sensitivity Analysis

We manage our exposure to market interest rates on our existing debt by controlling the mix of fixed and floating rate debt. As of March 31, 2020, after giving effect to our April 2020 Senior Notes offering and the application of the net proceeds therefrom, we had $2.3 billion of floating rate debt, none of which had LIBOR floors. As a result, a hypothetical unfavorable fluctuation in market interest rates on our existing debt of 1/8 of a percent point over a 12 month period would increase our interest expense by approximately $3 million.

Tabular Information

The following table provides information about our market risk related to changes in interest rates. The future principal payments and weighted-average interest rates are presented as of March 31, 2020, after giving effect to our April 2020 Senior Notes offering and the application of the net proceeds therefrom. These debt maturities reflect final maturity dates and do not consider the impact of the principal payments that commence following the anticipated repayment dates of certain debt (see footnotes (b) and (d)). The information presented below regarding the variable rate debt is supplementary to our sensitivity analysis regarding the impact of changes in the interest rates. See notes 5 and 6 to our condensed consolidated financial statements and the 2019 Form 10-K for additional information regarding our debt.

	Future Principal Payments and Interest Rates by the Debt Instruments' Contractual Year of Maturity
(In millions of dollars)	2020			2021			2022			2023			2024			Thereafter			Total			Fair Value(a)
Debt:
Fixed rate(b)	$	32		$	1,587		$	883		$	3,428		$	774		$	9,782		$	16,486		$	16,846
Average interest rate(b)(c)(d)	4.3		%	2.9		%	5.2		%	4.2		%	3.3		%	5.0		%	4.5		%
Variable rate(e)	$	44		$	88		$	117		$	176		$	1,917		$	—		$	2,342		$	2,342
Average interest rate(e)	1.5		%	1.4		%	1.4		%	1.5		%	1.6		%	—		%	1.6		%

(a) The fair value of our debt is based on indicative quotes (that is, non-binding quotes) from brokers that require judgment to interpret market information, including implied credit spreads for similar borrowings on recent trades or bid/ask offers. These fair values are not necessarily indicative of the amount which could be realized in a current market exchange.

(b) The impact of principal payments that will commence following the anticipated repayment dates is not considered. The Tower Revenue Notes have principal amounts of $300 million, $250 million, $700 million and $750 million, with anticipated repayment dates in 2022, 2023, 2025 and 2028, respectively.

(c) The average interest rate represents the weighted-average stated coupon rate (see footnote (d)).

(d) If the Tower Revenue Notes are not repaid in full by the applicable anticipated repayment dates, the applicable interest rate increases by approximately 5% per annum and monthly principal payments commence using the Excess Cash Flow (as defined in the indenture governing the applicable Tower Revenue Notes) of the issuers of the Tower Revenue Notes. The Tower Revenue Notes are presented based on their contractual maturity dates ranging from 2042 to 2048 and include the impact of an assumed 5% increase in interest rate that would occur following the anticipated repayment dates but exclude the impact of monthly principal payments that would commence using Excess Cash Flow of the issuers of the Tower Revenue Notes. The full year 2019 Excess Cash Flow of the issuers of the Tower Revenue Notes was approximately $764 million. We currently expect to refinance these notes on or prior to the respective anticipated repayment dates.

(e) Consists of our 2016 Term Loan A and 2016 Revolver borrowings, each of which matures in 2024.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

The Company conducted an evaluation, under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, of the effectiveness of the Company's disclosure controls and procedures as of the end of the period covered by this report. Based on this evaluation, the Chief Executive Officer and Chief Financial Officer concluded that due to the material weakness in the Company's internal control over financial reporting described below, the Company's disclosure controls and procedures were not effective in alerting them in a timely manner to material information relating to the Company required to be included in the Company's periodic reports under the Securities Exchange Act of 1934, as amended.

Material Weakness in Internal Control over Financial Reporting

As previously disclosed in the Company's 2019 Form 10-K, management concluded that a material weakness existed in the Company's internal control over financial reporting, as it did not effectively design and maintain controls related to the accounting for tower installation services.

Remediation of Material Weakness

Management has created a plan of remediation to strengthen its internal control over financial reporting. The remediation efforts include 1) revising its accounting policies for its tower installation services to identify and account for lease components and the related calculation of deferred revenue, and 2) making improvements to existing processes and controls related to the determination of the accuracy of capital expenditures made for permanent improvements associated with tower installation services. Management is implementing training with respect to the new processes and evaluating the need for additional resources.

Management believes that the measures described above will remediate the identified material weakness and strengthen the Company’s internal control over financial reporting. Management has begun to take these actions to remediate the material weakness and may take additional measures to strengthen its internal control environment.

Changes in Internal Control Over Financial Reporting

There have been no changes in the Company's internal control over financial reporting during the fiscal quarter covered by this report that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

See the disclosure in note 9 to our condensed consolidated financial statements set forth in Part I, Item 1 of this Quarterly Report on Form 10-Q.

ITEM 1A. RISK FACTORS

The following risk factor is provided to update the risk factors previously discussed in "Item 1A. Risk Factors" in the 2019 Form 10-K.

The impact of COVID-19 and related risks could materially affect our financial position, results of operations and cash flows.

The global spread of COVID-19 has created significant uncertainty and economic disruption. We have modified, and might further modify, our business practices as a result of the COVID-19 pandemic, the economic and social ramifications of the disease, and the societal and governmental responses in the communities in which we operate. See "Item 2. MD&A—General Overview—Coronavirus (COVID-19)" for further information. The extent to which the COVID-19 pandemic will affect our financial position, results of operations and cash flows is difficult to predict with certainty and depends on numerous evolving factors, including: the duration and scope of the pandemic; government, social, business and other actions that have been and will be taken in response to the pandemic; and the effect of the pandemic on short- and long-term general economic conditions. Among other things, COVID-19 and the Initiatives could (1) adversely affect the ability of our suppliers and vendors to provide products and services

32

to us; (2) result in decreased demand for our communications infrastructure; (3) make it more difficult for us to serve our tenants, including as a result of delays or suspensions in the issuance of permits or other authorizations needed to conduct our business; and (4) increase our cost of capital and adversely impact our access to capital. The potential effects of COVID-19 could also heighten the risks disclosed in many of our risk factors that are included in "Item 1A. Risk Factors" in the 2019 Form 10-K. Due to the speed with which the situation is developing and factors beyond our knowledge or control, including the duration and severity of COVID-19, as well as third-party actions taken to contain its spread and mitigate its public health effects, at this time we cannot estimate or predict with certainty the impact of COVID-19, the Initiatives, or the measures we take in response thereto on our financial position, results of operations and cash flows, particularly over the near to medium term, but the impact could be material.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The following table summarizes information with respect to purchase of our equity securities during the first quarter of 2020:

Period	Total Number of Shares Purchased	Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs	Maximum Number (or Approximate Dollar Value) of Shares that May Yet Be Purchased Under the Plans or Programs
	(In thousands)
January 1 - January 31 2020	1	$	141.24	—	—
February 1 - February 29, 2020	439	166.18		—	—
March 1 - March 31, 2020	1	150.54		—	—
Total	441	$	166.06	—	—

We paid $73 million in cash to effect these purchases. The shares purchased relate to shares withheld in connection with the payment of withholding taxes upon vesting of restricted stock units.

The fair value of cash and cash equivalents and restricted cash approximate the carrying value. The Company determines the fair value of its debt securities based on indicative, non-binding quotes from brokers. Quotes from brokers require judgment and are based on the brokers' interpretation of market information, including implied credit spreads for similar borrowings on recent trades or bid/ask prices or quotes from active markets if available. Since December 31, 2019, there have been no changes in the Company's valuation techniques used to measure fair values.

Restatement of Previously Issued Condensed Consolidated Financial Statements

The following tables summarize the impact of the restatement adjustments that were related to the timing of revenue recognition on its tower installation services. Specifically, the Company determined that its historical practice of recognizing the full transaction price as service revenues upon completion of an installation was not acceptable under GAAP. Instead, a portion of the transaction price for the Company's tower installation services, specifically the amounts associated with permanent improvements recorded as fixed assets, represent a lease component and should be recognized as site rental revenues on a ratable basis over the associated estimated lease term. In addition, the Company has also made other adjustments to the financial statements referenced above to correct errors that were not material to its condensed consolidated financial statements. Such immaterial adjustments are related to a revision in the presentation of certain tower installation activities from a gross basis to a net basis, including the associated removal of certain amounts historically categorized as capital expenditures.  These immaterial adjustments relate exclusively to the Company's Towers segment. Collectively, the restatement adjustments and other immaterial adjustments are referred to herein as "Historical Adjustments."

In addition to the restatement of the condensed consolidated financial statements, certain historical information in the notes to the condensed consolidated financial statements have been restated to reflect the impact of the Historical Adjustments.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes

The Company operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally entitled to a deduction for dividends that it pays and therefore is not subject to U.S. federal corporate income tax on its net taxable income that is currently distributed to its stockholders. The Company also may be subject to certain federal, state, local and foreign taxes on its income and assets, including (1) taxes on any undistributed income, (2) taxes related to the TRSs, (3) franchise taxes, (4) property taxes, and (5) transfer taxes. In addition, the Company could in certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Internal Revenue Code of 1986, as amended, to maintain qualification for taxation as a REIT.

The Company's TRS assets and operations will continue to be subject, as applicable, to federal and state corporate income taxes or to foreign taxes in the jurisdictions in which such assets and operations are located. The Company's foreign assets and operations (including its tower operations in Puerto Rico) are subject to foreign income taxes in the jurisdictions in which such assets and operations are located, regardless of whether they are included in a TRS or not.

For the three months ended March 31, 2020 and 2019, the Company's effective tax rate differed from the federal statutory rate predominately due to the Company's REIT status, including the dividends paid deduction.

Segment Reporting [Abstract]

Operating Segments

Operating Segments

The Company's operating segments consist of (1) Towers and (2) Fiber. The Towers segment provides access, including space or capacity, to the Company's approximately 40,000 towers geographically dispersed throughout the U.S. The Towers segment also reflects certain ancillary services relating to the Company's towers, predominately consisting of site development services and installation services. The Fiber segment provides access, including space or capacity, to the Company's approximately 80,000 route miles of fiber primarily supporting small cell networks and fiber solutions geographically dispersed throughout the U.S.

The measurements of profit or loss used by the Company's chief operating decision maker ("CODM") to evaluate the performance of its operating segments are (1) segment site rental gross margin, (2) segment services and other gross margin and (3) segment operating profit. The Company defines segment site rental gross margin as segment site rental revenues less segment site rental cost of operations, which excludes stock-based compensation expense and prepaid lease purchase price adjustments recorded in consolidated cost of operations. The Company defines segment services and other gross margin as segment services and other revenues less segment services and other cost of operations, which excludes stock-based compensation expense recorded in consolidated cost of operations. The Company defines segment operating profit as segment site rental gross margin plus segment services and other gross margin, 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.

The following table set forth the Company's segment operating results for the three months ended March 31, 2020 and 2019. Costs that are directly attributable to Towers and Fiber are assigned to those respective segments. Additionally, certain costs are shared across segments and are reflected in the Company's segment measures through allocations that management believes to be reasonable. The "Other" column (1) represents amounts excluded from specific segments, such as 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, interest income, other income (expense), income (loss) from discontinued operations, and stock-based compensation expense, and (2) reconciles segment operating profit to income (loss) before income taxes, as the amounts are not utilized in assessing each segment’s performance. The "Other" total assets balance includes corporate assets such as cash and cash equivalents which have not been allocated to specific segments. There are no significant revenues resulting from transactions between the Company's operating segments.

The table below also gives effect to the Historical Adjustments, as described in note 2. Each of the Historical Adjustments for the three months ended March 31, 2019 are attributable only to the Towers segment.

(b) Segment cost of operations excludes (1) stock-based compensation of $6 million for both of the three months ended March 31, 2020 and 2019, and (2) prepaid lease purchase price adjustments of $5 million for both of the three months ended March 31, 2020 and 2019. Selling, general and administrative expenses exclude stock-based compensation expense of $30 million and $23 million for the three months ended March 31, 2020 and 2019, respectively.

[1] The Company's finance leases and other obligations relate to land, fiber, vehicles, and other assets and bear interest rates ranging up to 10% and mature in periods ranging from less than one year to approximately 30 years.

[2] See the 2019 Form 10-K, including note 9, for additional information regarding the maturity and principal amortization provisions and interest rates relating to the Company's indebtedness.

[3] If the respective series of Tower Revenue Notes are not paid in full on or prior to an applicable anticipated repayment date, then Excess Cash Flow (as defined in the indenture) of the issuers of such notes will be used to repay principal of the applicable series and class of the Tower Revenue Notes, and additional interest (of an additional approximately 5% per annum) will accrue on the respective Tower Revenue Notes. As of March 31, 2020, the Tower Revenue Notes have principal amounts of $300 million, $250 million, $700 million and $750 million, with anticipated repayment dates in 2022, 2023, 2025 and 2028, respectively.

[4] Both the 2016 Revolver and 2016 Term Loan A bear interest, at our option, at either (1) LIBOR plus a credit spread ranging from 0.875% to 1.750% per annum or (2) an alternate base rate plus a credit spread ranging from 0.000% to 0.750% per annum, in each case, with the applicable credit spread based on the Company's senior unsecured debt rating. The Company pays a commitment fee ranging from 0.125% to 0.350%, based on the Company's senior unsecured debt rating, per annum on the undrawn available amount under the 2016 Revolver.

[5] As of March 31, 2020, the undrawn availability under the 2016 Revolver was $3.7 billion.

[6] Notes under the CP Program may be issued, repaid and re-issued from time to time, with an aggregate principal amount of Commercial Paper Notes outstanding under the CP Program at any time not to exceed $1.0 billion. The net proceeds of the Commercial Paper Notes are expected to be used for general corporate purposes. The maturities of the 2019 Commercial Paper Notes, when outstanding, may vary but may not exceed 397 days from the date of issue. The Commercial Paper Notes are issued under customary terms in the commercial paper market and are issued at a discount from par or, alternatively, can be issued at par and bear varying interest rates on a fixed or floating basis. As of March 31, 2020, there were no outstanding Commercial Paper Notes. At any point in time, the Company intends to maintain available commitments under its 2016 Revolver in an amount at least equal to the amount of Commercial Paper Notes outstanding. While any outstanding commercial paper issuances generally have short-term maturities, the Company classifies the outstanding issuances, when applicable, as long-term based on its ability and intent to refinance the outstanding issuances on a long-term basis.

(b) If the respective series of Tower Revenue Notes are not paid in full on or prior to an applicable anticipated repayment date, then Excess Cash Flow (as defined in the indenture) of the issuers of such notes will be used to repay principal of the applicable series and class of the Tower Revenue Notes, and additional interest (of an additional approximately 5% per annum) will accrue on the respective Tower Revenue Notes. As of March 31, 2020, the Tower Revenue Notes have principal amounts of $300 million, $250 million, $700 million and $750 million, with anticipated repayment dates in 2022, 2023, 2025 and 2028, respectively.

(c) The Company's finance leases and other obligations relate to land, fiber, vehicles, and other assets and bear interest rates ranging up to 10% and mature in periods ranging from less than one year to approximately 30 years.

(d) As of March 31, 2020, the undrawn availability under the 2016 Revolver was $3.7 billion.

(e) Both the 2016 Revolver and 2016 Term Loan A bear interest, at our option, at either (1) LIBOR plus a credit spread ranging from 0.875% to 1.750% per annum or (2) an alternate base rate plus a credit spread ranging from 0.000% to 0.750% per annum, in each case, with the applicable credit spread based on the Company's senior unsecured debt rating. The Company pays a commitment fee ranging from 0.125% to 0.350%, based on the Company's senior unsecured debt rating, per annum on the undrawn available amount under the 2016 Revolver.

(f)

Notes under the CP Program may be issued, repaid and re-issued from time to time, with an aggregate principal amount of Commercial Paper Notes outstanding under the CP Program at any time not to exceed $1.0 billion. The net proceeds of the Commercial Paper Notes are expected to be used for general corporate purposes. The maturities of the 2019 Commercial Paper Notes, when outstanding, may vary but may not exceed 397 days from the date of issue. The Commercial Paper Notes are issued under customary terms in the commercial paper market and are issued at a discount from par or, alternatively, can be issued at par and bear varying interest rates on a fixed or floating basis. As of March 31, 2020, there were no outstanding Commercial Paper Notes. At any point in time, the Company intends to maintain available commitments under its 2016 Revolver in an amount at least equal to the amount of Commercial Paper Notes outstanding. While any outstanding commercial paper issuances generally have short-term maturities, the Company classifies the outstanding issuances, when applicable, as long-term based on its ability and intent to refinance the outstanding issuances on a long-term basis.

General

The information contained in the following notes to the condensed consolidated financial statements is condensed from that which would appear in the annual consolidated financial statements; accordingly, the condensed consolidated financial statements included herein should be reviewed in conjunction with the consolidated financial statements for the fiscal year ended December 31, 2019, and related notes thereto, included in the 2019 Form 10-K filed by Crown Castle International Corp. ("CCIC") with the SEC. Capitalized terms used but not defined in these notes to the condensed consolidated financial statements have the same meaning given to them in the 2019 Form 10-K. References to the "Company" refer to CCIC and its predecessor, as applicable, and their subsidiaries, unless otherwise indicated or the context indicates otherwise. As used herein, the term "including," and any variation thereof means "including without limitation." The use of the word "or" herein is not exclusive. Unless the context suggests otherwise, references to "U.S." are to the United States of America and Puerto Rico, collectively.

The Company owns, operates and leases shared communications infrastructure that is geographically dispersed throughout the U.S., including (1) towers and other structures, such as rooftops (collectively, "towers"), and (2) fiber primarily supporting small cell networks ("small cells") and fiber solutions. The Company's towers, fiber and small cells assets are collectively referred to herein as "communications infrastructure," and the Company's customers on its communications infrastructure are referred to herein as "tenants."

The Company's core business is providing access, including space or capacity, to its shared communications infrastructure via long-term contracts in various forms, including lease, license, sublease and service agreements (collectively, " tenant contracts").

The Company's operating segments consist of (1) Towers and (2) Fiber. See note 11.

As part of the Company's effort to provide comprehensive communications infrastructure solutions, as an ancillary business, the Company also offers certain services primarily relating to its Towers segment, predominately consisting of (1) site development services primarily relating to existing or new tenant equipment installations, including: site acquisition, architectural and engineering, or zoning and permitting (collectively, "site development services") and (2) tenant equipment installation or subsequent augmentations (collectively, "installation services").

The Company operates as a REIT for U.S. federal income tax purposes. In addition, the Company has certain taxable REIT subsidiaries ("TRSs"). See note 7.

Approximately 53% of the Company's towers are leased or subleased or operated and managed under master leases, subleases, and other agreements with AT&T, Sprint and T-Mobile. The Company has the option to purchase these towers at the end of their respective lease terms. The Company has no obligation to exercise such purchase options.

Basis of Presentation

The condensed consolidated financial statements included herein are unaudited; however, they include all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to state fairly the consolidated financial position of the Company at March 31, 2020, the condensed consolidated results of operations for the three months ended March 31, 2020 and 2019, and the condensed consolidated cash flows for the three months ended March 31, 2020 and 2019. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

(a) See the 2019 Form 10-K, including note 9, for additional information regarding the maturity and principal amortization provisions and interest rates relating to the Company's indebtedness.

(b) If the respective series of Tower Revenue Notes are not paid in full on or prior to an applicable anticipated repayment date, then Excess Cash Flow (as defined in the indenture) of the issuers of such notes will be used to repay principal of the applicable series and class of the Tower Revenue Notes, and additional interest (of an additional approximately 5% per annum) will accrue on the respective Tower Revenue Notes. As of March 31, 2020, the Tower Revenue Notes have principal amounts of $300 million, $250 million, $700 million and $750 million, with anticipated repayment dates in 2022, 2023, 2025 and 2028, respectively.

(c) The Company's finance leases and other obligations relate to land, fiber, vehicles, and other assets and bear interest rates ranging up to 10% and mature in periods ranging from less than one year to approximately 30 years.

(d) As of March 31, 2020, the undrawn availability under the 2016 Revolver was $3.7 billion.

(e) Both the 2016 Revolver and 2016 Term Loan A bear interest, at our option, at either (1) LIBOR plus a credit spread ranging from 0.875% to 1.750% per annum or (2) an alternate base rate plus a credit spread ranging from 0.000% to 0.750% per annum, in each case, with the applicable credit spread based on the Company's senior unsecured debt rating. The Company pays a commitment fee ranging from 0.125% to 0.350%, based on the Company's senior unsecured debt rating, per annum on the undrawn available amount under the 2016 Revolver.

(f) Notes under the CP Program may be issued, repaid and re-issued from time to time, with an aggregate principal amount of Commercial Paper Notes outstanding under the CP Program at any time not to exceed $1.0 billion. The net proceeds of the Commercial Paper Notes are expected to be used for general corporate purposes. The maturities of the 2019 Commercial Paper Notes, when outstanding, may vary but may not exceed 397 days from the date of issue. The Commercial Paper Notes are issued under customary terms in the commercial paper market and are issued at a discount from par or, alternatively, can be issued at par and bear varying interest rates on a fixed or floating basis. As of March 31, 2020, there were no outstanding Commercial Paper Notes. At any point in time, the Company intends to maintain available commitments under its 2016 Revolver in an amount at least equal to the amount of Commercial Paper Notes outstanding. While any outstanding commercial paper issuances generally have short-term maturities, the Company classifies the outstanding issuances, when applicable, as long-term based on its ability and intent to refinance the outstanding issuances on a long-term basis.

The following are the scheduled principal payments and final maturities of the total debt and other long-term obligations of the Company outstanding as of March 31, 2020, which do not consider the principal payments that will commence following the anticipated repayment dates on the Tower Revenue Notes.

Commitments and Contingencies

Commitments and Contingencies

The Company is involved in various claims, lawsuits or proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs or losses that may be incurred, if any, management believes the resolution of such uncertainties and the incurrence of such costs should not have a material adverse effect on the Company's condensed consolidated financial position or results of operations. Additionally, the Company and certain of its subsidiaries are contingently liable for commitments or performance guarantees arising in the ordinary course of business, including certain letters of credit or surety bonds. In addition, see note 1 for a discussion of the Company's option to purchase approximately 53% of its towers at the end of their respective lease terms. The Company has no obligation to exercise such purchase options.

SEC Investigation

In September 2019, the Company received a subpoena from the SEC requesting certain documents from 2015 through the present, primarily related to the Company's long-standing capitalization and expense policies for tenant upgrades and installations in its services business. Prior to receiving this subpoena, the Company previously provided information to the SEC related to certain services-related transactions. The Company is cooperating fully with the SEC's investigation and cannot predict the ultimate timing, scope or outcome of this matter.

Shareholder Litigation

In February and March 2020, putative securities class action suits were filed in the United States District Court for the District of New Jersey against the Company and certain of its current officers. The lawsuits were filed on behalf of investors that purchased or otherwise acquired stock of the Company between February 26, 2018 and February 26, 2020. The allegations relate to allegedly false or misleading statements or other failures to disclose information about the Company's business, operations and prospects. The complaints seek unspecified money damages and the award of plaintiffs' costs and expenses incurred in the respective class action. The Company is currently unable to determine the likelihood of an outcome or estimate a range of reasonably possible losses, if any, with respect to these lawsuits. The Company believes these lawsuits are without merit and intends to defend itself vigorously.

In April 2020, a stockholder derivative lawsuit was filed by Melvyn Klein in the United States District Court for the District of Delaware, against the Company, as a nominal defendant, and its current directors and certain of its current officers. The complaint alleges, among other things, breaches of fiduciary duties, waste of corporate assets, unjust enrichment, and false or misleading statements, between February 27, 2018 through the present. The complaint seeks, among other things, unspecified money damages, costs and expenses, restitution from the defendants, and an order requiring the Company to implement certain corporate governance reforms. As a nominal defendant, no monetary relief is sought against the Company itself.

Revenues

Site rental revenues

The Company generates site rental revenues from its core business by providing tenants with access, including space or capacity, to its shared communications infrastructure via long-term tenant contracts in various forms, including lease, license, sublease and service agreements. Providing such access over the length of the tenant contract term represents the Company’s sole performance obligation under its tenant contracts.

Site rental revenues from the Company's tenant contracts are recognized on a straight-line, ratable basis over the fixed, non-cancelable term of the relevant tenant contract, which generally ranges from five to 15 years for wireless tenants and three to 20 years for the Company's fiber solutions tenants (including from organizations with high-bandwidth and multi-location demands), regardless of whether the payments from the tenant are received in equal monthly amounts during the life of the tenant contract. Certain of the Company's tenant contracts contain (1) fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the CPI), (2) multiple renewal periods exercisable at the tenant's option and (3) only limited termination rights at the applicable tenant's option through the current term. If the payment terms call for fixed escalations, upfront payments, or rent-free periods, the revenue is recognized on a straight-line basis over the fixed, non-cancelable term of the agreement. When calculating straight-line rental revenues, the Company considers all fixed elements of tenant contractual escalation provisions, even if such escalation provisions contain a variable element in addition to a minimum. The Company's assets related to straight-line site rental revenues include current amounts of $123 million included in "Other current assets" and non-current amounts of $1.4 billion included in "Deferred site rental receivables" as of March 31, 2020. Amounts billed or received prior to being earned are deferred and reflected in "Deferred revenues" and "Other long-term liabilities." Amounts to which the Company has an unconditional right to payment, which are related to both satisfied or partially satisfied performance obligations, are recorded within "Receivables, net" on the Company's condensed consolidated balance sheet.

Services and other revenues

As part of the Company’s effort to provide comprehensive communications infrastructure solutions, as an ancillary business, the Company offers certain services primarily relating to its Towers segment, predominately consisting of (1) site development services and (2) installation services. Upon contract commencement, the Company assesses its services to tenants and identifies performance obligations for each promise to provide a distinct service.

The Company may have multiple performance obligations for site development services, which primarily include: structural analysis, zoning, permitting and construction drawings. For each of the above performance obligations, services revenues are recognized at completion of the applicable performance obligation, which represents the point at which the Company believes it has transferred goods or services to the tenant. The revenue recognized is based on an allocation of the transaction price among the performance obligations in a respective contract based on estimated standalone selling price. The volume and mix of site development services may vary among contracts and may include a combination of some or all of the above performance obligations. Payments generally are due within 45 to 60 days and generally do not contain variable-consideration provisions. The transaction price for the Company's tower installation services consists of amounts for (1) permanent improvements to the Company's towers that represent a lease component and (2) the performance of the service. Amounts under the Company's tower installation service agreements that represent a lease component are recognized as site rental revenues on a straight-line basis over the length of the associated estimated lease term. For the performance of the installation service, the Company has one performance obligation, which is satisfied at the time of the applicable installation or augmentation and recognized as services and other revenues. Since performance obligations are typically satisfied prior to receiving payment from tenants, the unconditional right to payment is

recorded within "Receivables, net" on the Company’s condensed consolidated balance sheet. The vast majority of the Company’s services generally have a duration of one year or less.

Additional information on revenues

The following additional information on revenues reflect the impact of the Historical Adjustments, where applicable, as discussed in note 2. As of January 1, 2020 and March 31, 2020, $2.9 billion and $2.8 billion, respectively, of unrecognized revenue was reported in "Deferred revenues" and "Other long-term liabilities" on our condensed consolidated balance sheet. During the three months ended March 31, 2020, approximately $160 million of the January 1, 2020 unrecognized revenue balance was recognized as revenue. During the three months ended March 31, 2019, approximately $135 million of the January 1, 2019 unrecognized revenue balance was recognized as revenue.

The following table is a summary of the non-cancelable contracted amounts owed to the Company by tenants pursuant to tenant contracts in effect as of March 31, 2020.

	Nine Months Ending December 31,		Years Ending December 31,

Earnings Per Share [Abstract]

Per Share Information

Per Share Information

Basic net income (loss) attributable to CCIC common stockholders, per common share, excludes dilution and is computed by dividing net income (loss) attributable to CCIC common stockholders by the weighted-average number of common shares outstanding during the period. For the three months ended March 31, 2020 and 2019, diluted net income (loss) attributable to CCIC common stockholders, per common share, is computed by dividing net income (loss) attributable to CCIC common stockholders by the weighted-average number of common shares outstanding during the period, plus any potential dilutive common share equivalents, including shares issuable upon (1) the vesting of restricted stock units as determined under the treasury stock method and (2) conversion of the Company's 6.875% Mandatory Convertible Preferred Stock, as determined under the if-converted method. The table below also gives effect to the Historical Adjustments, as described in note 2.

	Three Months Ended March 31,

Dividends/distributions declared per share of common stock	$	1.20		$	1.125
Dividends/distributions declared per share of preferred stock	$	17.1875		$	17.1875

During the three months ended March 31, 2020, the Company granted one million restricted stock units. For the three months ended March 31, 2020, 15 million common share equivalents related to the 6.875% Mandatory Convertible Preferred Stock were excluded from the dilutive common shares because the impact of such conversion would be anti-dilutive, based on the Company's common stock price as of March 31, 2020.
