Item 1.     Business

Overview

PART I

We own, operate and lease shared communications infrastructure that is geographically dispersed throughout the U.S., including more than (1) 40,000 towers and other structures, such as rooftops (collectively, "towers"),
and (2) 80,000 route miles of fiber primarily supporting small cell networks ("small cells") and fiber solutions. We refer to our towers, fiber and small cells assets collectively as "communications infrastructure," and to our
customers on our communications infrastructure as "tenants." Our operating segments consist of (1) Towers and (2) Fiber, which includes both small cells and fiber solutions. Our core business is providing access, including
space or capacity, to our shared communications infrastructure via long-term contracts in various forms, including lease, license, sublease and service agreements (collectively, "tenant contracts"). We seek to increase our site
rental revenues by adding more tenants on our shared communications infrastructure, which we expect to result in significant incremental cash flows due to our low incremental operating costs. We operate as a REIT for U.S.
federal income tax purposes. See "Item 1. Business—REIT Status" and notes 2 and 9 to our consolidated financial statements.

Over  the  last  two  decades,  we  have  assembled  a  leading  portfolio  of  towers  predominately  through  acquisitions  from  large  wireless  carriers  or  their  predecessors.  More  recently,  both  through  acquisitions  and  new
construction of small cells and fiber, we have extended our communications infrastructure presence by investing significantly in our Fiber segment. Through our product offerings of towers and small cells, we seek to provide a
comprehensive solution to enable our wireless tenants to expand coverage and capacity for wireless networks. Furthermore, within our Fiber segment, we seek to generate cash flow growth and stockholder return by deploying
our fiber for both small cells' and fiber solutions' tenants.

Approximately  56%  and  71%  of  our  towers  are  located  in  the  50  and  100  largest  U.S.  basic  trading  areas  ("BTAs"),  respectively.  Our  towers  have  a  significant  presence  in  each  of  the  top  100  BTAs.  We  derive
approximately 40% of our Towers site rental gross margin from towers located on land that we own, including through fee interests and perpetual easements, and we derive approximately 60% of our Towers site rental gross
margin from towers located on land that we lease, sublease, manage or license. The contracts for the land under our towers have an average total remaining life of approximately 36 years (including all renewal terms exercisable
at our option), weighted based on Towers site rental gross margin. The majority of our small cells and fiber are located in major metropolitan areas, including a presence within every major U.S. market. The vast majority of our
fiber assets are located on public rights-of-way.

Our  largest  tenants  are  T-Mobile,  AT&T  and  Verizon  Wireless,  which  collectively  accounted  for  approximately  three-fourths  of  our  2021  consolidated  site  rental  revenues.  See  note  14  to  our  consolidated  financial
statements for further information regarding our largest tenants. Site rental revenues represented 90% of our 2021 consolidated net revenues, of which 67% and 33% were from our Towers segment and our Fiber segment,
respectively. Within our Fiber segment, 69% and 31% of our 2021 Fiber site rental revenues related to fiber solutions and small cells, respectively. The vast majority of our site rental revenues are of a recurring nature and are
derived from long-term tenant contracts with our tenants.

Our site rental revenues derived from wireless tenants typically result from long-term tenant contracts with (1) initial terms of five to 15 years, (2) multiple renewal periods of five to 10 years each, exercisable at the option
of the tenant, (3) limited termination rights for our tenants and (4) monthly rental payments with contractual escalations of the rental price and, in some cases, an additional upfront payment. Our site rental revenues derived from
our fiber solutions tenants (including from organizations with high-bandwidth and multi-location demands) typically result from tenant contracts with (1) initial terms that generally vary between three to 20 years and (2) a fixed
monthly  recurring  fee  and,  in  some  cases,  an  additional  upfront  payment.  As  of  December  31,  2021,  exclusive  of  renewals  exercisable  at  the  tenants'  option,  our  tenant  contracts  had  a  weighted-average  remaining  life  of
approximately five years and represented $31 billion of expected future cash inflows.

As part of our effort to provide comprehensive communications infrastructure solutions, as an ancillary business, we also offer certain services primarily relating to our 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").

Strategy

As  a  leading  provider  of  shared  communications  infrastructure  in  the  U.S.,  our  strategy  is  to  create  long-term  stockholder  value  via  a  combination  of  (1)  growing  cash  flows  generated  from  our  existing  portfolio  of
communications infrastructure, (2) returning a meaningful portion of our cash generated by operating activities to our common stockholders in the form of dividends and (3) investing capital efficiently to grow cash flows and
long-term dividends per share. Our  strategy  is  based,  in  part,  on  our  belief  that  the  U.S.  is  the  most  attractive  market  for  shared  communications  infrastructure  investment  with  the  greatest  long-term  growth  potential.  We
measure our efforts to create "long-term stockholder value" by the combined payment of dividends to stockholders and growth in our per-share results. The key elements of our strategy are to:

•

•

•

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

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

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

construction of towers, fiber and small cells;
acquisitions of towers, fiber and small cells;
acquisitions of land interests (which primarily relate to land assets under towers);
improvements and structural enhancements to our existing communications infrastructure;

◦
◦
◦
◦
◦ purchases of shares of our common stock from time to time; and
◦ purchases, repayments or redemptions of our debt.

Our strategy to create long-term stockholder value is based on our belief that there will be considerable future demand for our communications infrastructure based on the location of our assets and the rapid 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.

REIT Status

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 net
taxable income that is currently distributed to our stockholders. We may be subject to certain federal, state, local and foreign taxes on our income or assets, including (1) taxes on any undistributed income, (2) taxes related to our
taxable REIT subsidiaries ("TRSs"), (3) franchise taxes, (4) property taxes and (5) transfer taxes. In addition, we could, under 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 ("Code"), to maintain qualification for taxation as a REIT. For taxable years beginning before 2026, qualified REIT
dividends (within the meaning of Section 199A(e)(3) of the Code) constitute a part of a non-corporate taxpayer's "qualified business income amount" and thus our non-corporate U.S. stockholders may be eligible to take a
qualified business income deduction in an amount equal to 20% of such dividends received from us. Without further legislative action, the 20% deduction applicable to qualified REIT dividends will expire on January 1, 2026.

The vast majority of our assets and revenues are in the REIT. See notes 2 and 9 to our consolidated financial statements. Additionally, we have included in TRSs certain other assets and operations. Those 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.

Our foreign assets and operations (including our tower operations in Puerto Rico) most likely will be 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.

To remain qualified and be 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 notes 2 and 9 to our consolidated financial statements). Our quarterly common stock dividend will delay the utilization of our NOLs and may cause certain of the
NOLs to expire without utilization. See "Item 1A. Risk Factors" for risks associated with our REIT status.

Industry Overview

Consumer demand for data continues to grow due to increases in data consumption and increased penetration of bandwidth-intensive devices. This increase in data consumption is driven by factors such as growth in (1)
mobile  entertainment  (such  as  mobile  video,  mobile  applications  and  social  networking),  (2)  mobile  internet  usage  (supporting  web  browsing  and  trends  in  telehealth,  remote  working,  online  learning  and  other  remote
communications), (3) machine-to-machine applications or the "Internet of Things" (such as connected cars and smart city technologies), and (4) the adoption of other bandwidth-intensive applications (such as cloud services and
video communications). As a result, consumer wireless devices are trending toward bandwidth-intensive devices, including smartphones, laptops, tablets, wearables and other emerging and embedded devices, and U.S. wireless
carriers are among the first carriers in the world to begin offering commercial 5th Generation ("5G") mobile cellular communications services to further support such growth.

We expect the following anticipated factors to contribute to potential demand for our communications infrastructure:

•

•

•

•

•

consumers'  growing  wireless  data  consumption  leading  major  wireless  carriers  to  upgrade  and  enhance  their  networks  through  the  efficient  use  of  both  towers  and  small  cells,  including  in  connection  with  5G
deployments, in an effort to improve network quality and capacity and customer retention or satisfaction;

prior and future potential spectrum auctioned, licensed or made available by the Federal Communications Commission ("FCC") enabling additional wireless carrier network development;

next-generation technologies and new uses for wireless communications may potentially result in new entrants or increased demand in the wireless industry, which may include companies involved in the continued
evolution and deployment of the Internet of Things;

the continued adoption of bandwidth-intensive applications could result in demand for high-capacity, multi-location, fiber-based network solutions; and

increased government initiatives to expand broadband infrastructure to support connectivity throughout the U.S.

6

The Company

Virtually all of our operations in both our Towers and Fiber operating segments are located in the U.S. For more information about our operating segments, see "Item 7. MD&A—General Overview" and note 14 to our
consolidated financial statements. Our core business is providing access, including space or capacity, to our shared communications infrastructure via long-term tenant contracts in the U.S. We believe our communications
infrastructure is integral to our tenants' networks and organizations. See "Item 1. Business—Strategy."

Towers Segment. We believe towers are the most efficient and cost-effective solution for providing coverage and capacity for wireless carrier network deployments. We acquired ownership interests or exclusive rights to
the majority of our towers directly or indirectly from the largest U.S. wireless carriers (or their predecessors) through transactions consummated since 1999, including transactions with (1) AT&T in 2013 ("AT&T Acquisition"),
(2) T-Mobile in 2012 ("T-Mobile Acquisition"), (3) Global Signal Inc. in 2007 ("Global Signal Acquisition"), which had originally acquired the majority of its towers from Sprint (prior to Sprint's merger with T-Mobile, which
was completed in 2020), (4) companies now part of Verizon Wireless in 1999 and 2000 and (5) companies now part of AT&T in 1999 and 2000.

We generally receive monthly rental payments from our Towers tenants pursuant to long-term tenant contracts. Typically, we negotiate initial contract terms of five to 15 years, with multiple renewal periods of five to 10
years each, exercisable at the option of the tenant, and our tenant contracts typically include fixed escalations (which generally exceed expected non-renewals, as discussed below). We strive to negotiate with our existing tenant
base for longer contractual terms, which often contain fixed escalation rates. For example, on January 6, 2022, we entered into a 12-year agreement with T-Mobile ("T-Mobile Agreement"), which includes contracted new tower
leasing activity and a base escalator that is consistent with historical levels for our Towers segment.

Our Towers tenant contracts, while amended and re-negotiated over time, have historically led to a long-term relationship with tenants on our towers, resulting in a retention rate generally between 98% and 99% each year.
In general, each renewable tenant contract automatically renews at the end of its term unless (1) the tenant provides prior notice of its intent not to renew or (2) the contract is amended or re-negotiated. See "Item 1A. Risk
Factors" for additional information regarding expected higher non-renewals (which we define as the reduction in site rental revenues as a result of tenant churn, terminations and, in limited circumstances, reductions of existing
lease  rates)  as  a  result  of  the  T-Mobile  Agreement.  See  note  3  to  our  consolidated  financial  statements  for  a  tabular  presentation  of  the  minimum  rental  payments  due  to  us  by  tenants  pursuant  to  tenant  contracts  without
consideration of tenant renewal options as of December 31, 2021.

The average monthly rental payment from a new tenant added to towers can vary based on (1) aggregate tenant volume, (2) the location of the tower, or (3) the amount of tower and ground space leased to a tenant, which
can be influenced by the quantity, size, and weight of the tenant's antenna installation or related equipment. When possible, we seek to receive rental payment increases in connection with tenant contract amendments, pursuant
to which our tenants add antennas or other equipment to our towers or ground space on which they already have equipment pursuant to preexisting tenant contracts. Our Towers tenant contracts and pricing are not influenced by
whether or not we perform the respective site development or installation services. See "—Services" below for a further discussion of our tower installation services.

7

As of December 31, 2021, the average number of tenants (calculated as a unique license together with any related amendments thereto) per tower is approximately 2.3. The following chart sets forth the number of existing
tenants per tower as of December 31, 2021 (see "Item 7. MD&A—Accounting and Reporting Matters—Critical Accounting Policies and Estimates" for a discussion of our impairment evaluation and our towers with no tenants).

Fiber Segment. Our Fiber segment includes both small cells and fiber solutions.

• Our small cells offload data traffic from towers and bolster our tenants' network capacity where data demand is the greatest and are typically attached to public right-of-way infrastructure, including utility poles and

street lights.

• We  offer  certain  fiber  solutions  to  organizations  with  high-bandwidth  and  multi-location  demands.  Our  fiber  solutions  provide  essential  connectivity  resources  needed  to  create  integrated  networks  and  support

organizations.

Our fiber assets include those we acquired from: (1) NextG Networks, Inc. in 2012, (2) Quanta Fiber Networks, Inc. in 2015, (3) FPL FiberNet Holdings, LLC and certain other subsidiaries of NextEra Energy, Inc. in 2017,

(4) Wilcon Holdings LLC in 2017 and (5) LTS Group Holdings LLC in 2017.

We generally receive monthly recurring payments from our Fiber tenants and, in some cases, receive upfront payments, pursuant to tenant contracts. The average monthly rental payment from a new tenant can vary based
on the amount or cost of (1) construction for initial and subsequent tenants, (2) fiber strand requirements and supply, (3) equipment at the site, (4) the market in the U.S. where the fiber is located and (5) any upfront payment
received. The T-Mobile Agreement also includes a contractual commitment by T-Mobile for 35,000 new small cell nodes, including specific commitments in each of the next five years.

Additional site rental information. For both our Towers and Fiber segments, we have existing master agreements with our largest tenants, including T-Mobile, AT&T and Verizon Wireless. Such agreements provide certain

terms (including economic terms) that govern underlying contracts (entered into during the term of the master agreements) regarding the right to use our communications infrastructure by such tenants.

Approximately half of our site rental cost of operations consists of Towers ground lease expenses, and the remainder includes fiber access expenses (primarily leases of fiber assets and other access agreements to facilitate
our communications infrastructure), property taxes, repairs and maintenance, employee compensation or related benefit costs, and utilities. Assuming current leasing activity levels, our cash operating expenses generally tend to
escalate  at  approximately  the  rate  of  inflation.  We  seek  to  add  tenants  to  our  existing  communications  infrastructure  assets  at  a  low  incremental  operating  cost,  delivering  high  incremental  returns  to  our  business.  Once
constructed, our communications infrastructure portfolio requires minimal sustaining capital expenditures, including maintenance or other non-discretionary capital expenditures, which are typically approximately 2% of net
revenues. See note 13 to our consolidated financial statements for a tabular presentation of the rental payments we owe to landlords pursuant to our operating lease agreements.

Services. As part of our effort to provide comprehensive communications infrastructure solutions, as an ancillary business, we also offer certain services primarily relating to our Towers segment, predominately consisting

of (1) site development services and (2) installation services. For 2021, approximately 40% of our services and other revenues related to

8

installation services, and the remainder predominately related to site development services. We seek to grow our service revenues by capitalizing on (1) increased leasing volumes that may result from carrier network upgrades,
(2) promoting site development services, (3) expanding the scope of our services, and (4) focusing on tenant service and deployment speed. We have the capability and expertise to install, with the assistance of our network of
subcontractors, equipment or antenna systems for our tenants. We do not always provide the installation services or site development services for our tenants on our communications infrastructure as other service providers also
provide these services (see also "—Competition" below). These services are typically non-recurring and highly competitive, with several competitors in most markets. Typically, our site development services and installation
services are billed on a fixed fee basis. The terms and pricing of both site development services and installation services are negotiated separately from our tenant contracts.

Customers. Our Towers customers are primarily comprised of large wireless carriers that operate national networks.

Our Fiber customers generally consist of large wireless carriers and organizations with high-bandwidth and multi-location demands, such as enterprise, government, education, healthcare, wholesale, financial, legal, media

and entertainment, content distribution, and energy and utilities customers.

Our three largest tenants are T-Mobile, AT&T and Verizon Wireless. Collectively, these three tenants accounted for approximately three-fourths of our 2021 site rental revenues . See "Item 1A. Risk Factors" for risks

associated with our dependence on a small number of customers and note 14 to our consolidated financial statements. For 2021, our site rental revenues by tenant were as follows:

Sales  and  Marketing.  Our  sales  organization  markets  our  communications  infrastructure  with  the  objective  of  contracting  access  with  tenants  to  existing  communications  infrastructure  or  to  new  communications
infrastructure prior to construction. We seek to become the critical partner and preferred independent communications infrastructure provider for our tenants and increase tenant satisfaction relative to our peers by leveraging our
(1) existing unique communications infrastructure footprint, (2) tenant relationships, (3) process-centric approach, (4) technological tools and (5) construction capabilities and expertise.

Our sales team is organized based on a variety of factors, including tenant type (such as large wireless carriers, vertical customers and organizations), product offering and geography. A team of national account directors
maintains our relationships with our largest tenants. These directors work to develop new business opportunities, as well as to ensure that tenants' communications infrastructure needs are efficiently translated into new contracts
for our communications infrastructure. Sales personnel in our local offices develop and maintain relationships with our tenants that are expanding their networks, entering new markets, seeking new or additional communication
infrastructure offerings, bringing new technologies to market or requiring maintenance or add-on business. In addition to our full-time sales or marketing staff, a number of senior-level employees spend a significant portion of
their time on sales and marketing activities and call on existing or prospective tenants.

Competition.  We  face  competition  for  site  rental  tenants  from  various  sources,  including  (1)  other  independent  communications  infrastructure  owners  or  operators,  including  competitors  that  own,  operate,  or  manage
towers,  rooftops,  broadcast  or  transmission  towers,  utility  poles,  fiber  (including  non-traditional  competitors  such  as  cable  providers)  or  small  cells,  (2)  tenants  who  elect  to  self-perform  or  (3)  new  alternative  deployment
methods for communications infrastructure.

9

Some of our largest competitors in the Towers segment are American Tower Corporation and SBA Communications Corporation. Our Fiber segment business competitors can vary significantly based on geography. Some
of  the  larger  competitors  in  the  Fiber  segment  include  other  owners  of  fiber,  as  well  as  recent  and  potential  entrants  into  small  cells  and  the  fiber  solutions  business.  We  believe  that  location,  existing  communications
infrastructure footprint, deployment speed, quality of service, expertise, reputation, capacity and price have been and will continue to be the most significant competitive factors affecting our businesses. See "Item 1A. Risk
Factors" for a discussion of competition in our industry.

Competitors  to  our  services  offering  can  include  site  acquisition  consultants,  zoning  consultants,  real  estate  firms,  right-of-way  consulting  firms,  construction  companies,  tower  owners  or  managers,  radio  frequency
engineering consultants, our tenants' internal staff or contractors, or telecommunications equipment vendors who can provide turnkey site development services through multiple subcontractors. We believe that our tenants base
their decisions on the outsourcing of services on criteria such as a company's experience, record of accomplishment, reputation, price and time for completion of a project.

Environmental, Social and Governance ("ESG")

Our  shared  communications  infrastructure  model  results  in  the  use  of  fewer  resources,  including  water,  energy,  metals  and  other  materials,  than  would  otherwise  be  needed  to  construct  and  maintain  communications
infrastructure. We are committed to operating responsibly and ethically and considering social and environmental impacts as we make business decisions. In 2021, we incorporated annual sustainability targets into our senior
unsecured credit facility and announced our goal to be carbon neutral by 2025 in Scope 1 and 2 emissions by continuing to invest in energy reduction initiatives, sourcing renewable energy, and, to a lesser extent, utilizing
carbon credits or offsets. We plan to continue investing in projects that are both good for our business and good for the environment.

Additionally, in 2021, our board of directors expanded the responsibilities of the Nominating, Environmental, Social and Governance Committee (formerly, the Nominating & Corporate Governance Committee) to include
assisting the board of directors with ESG oversight. Our executive management team and senior management keep our board of directors apprised of our ESG priorities, goals and initiatives. Together, our board of directors and
executive management team define our strategic approach to managing actual and potential impacts of significant ESG risks and opportunities.

Additional information regarding our sustainability initiatives and progress is also available through the investor section of our website at https://www.crowncastle.com/investors/corporate-sustainability. The information
on our website, including our most recent ESG Report, is not, and shall not be deemed to be, incorporated by reference into this 2021 Form 10-K or any other filings with the SEC unless expressly noted in any such other filings.

Human Capital

The people who work for Crown Castle are essential to our ability to execute on our strategy. At January 31, 2022, we employed approximately 5,000 people, all of whom were based in the U.S. Of our total employees,

approximately 12% were field workers. From time to time, we also add contingent workers to support our business.

We believe attracting, developing and retaining talented employees is paramount to serving our customers and our communities and creating value for our shareholders. Our B3 values (Be Real, Be Accountable and Be an

Owner) shape our culture, drive our decision-making and guide our interactions with one another and our customers. Our 2021 annual employee survey indicated strong employee engagement exceeding U.S. company norms.

We  continue  to  focus  on  building  and  retaining  a  more  diverse  workforce  and  a  more  inclusive  community  to  make  our  company  stronger  and  more  innovative.  We  actively  partner  with  non-profit  and  community

organizations to create a diverse talent pipeline. In addition, our board of directors is currently comprised of 50% female or racially diverse directors, including each of the four most recently appointed directors.

The well-being of our employees is a crucial element of our safety culture, employee engagement and productivity. We offer a competitive total rewards package which includes market-based pay, performance-based
annual  incentive  awards,  healthcare  and  retirement  benefits,  mental  health  benefits,  parental  and  family  leave,  holiday  and  paid  time  off  and  tuition  assistance.  We  further  invest  in  our  employees'  professional  growth  and
development by providing resources and opportunities to hone their skills and expand their subject-matter expertise, which empowers them to advance their careers and enables our business to prosper.

We are not a party to any collective bargaining agreements and have not experienced any strikes or work stoppages. See also "Item 7. MD&A(cid:0)General Overview(cid:0)COVID-19" for information on the measures we have

taken with respect to our workforce in light of the global outbreak of the novel coronavirus (COVID-19).

Regulatory and Environmental Matters

We are required to comply with a variety of federal, state and local regulations and laws in the U.S., including FCC and Federal Aviation Administration ("FAA") regulations and those discussed under "—Environmental"
below. To date, we have not incurred any material fines or penalties or experienced any material adverse effects to our business as a result of any domestic or international regulations, including any environmental regulations.
The summary below is based on regulations currently in effect, and such regulations are subject to review or modification by the applicable governmental authority from time to time. If we fail to comply with applicable laws
and regulations, we may be fined or even lose our rights to conduct some of our business.

Federal Regulations. Both the FCC and the FAA regulate towers used for wireless communications, radio, or television broadcasting. Such regulations control the siting, construction, modification, lighting, and marking of
towers and may, depending on the characteristics of particular towers, require the registration of tower facilities with the FCC and the issuance of determinations confirming no hazard to air traffic. Wireless communications
devices operating on towers are separately regulated and independently licensed based upon the particular frequency used. In addition, the FCC and the FAA have developed standards to consider proposals for new or modified
tower or antenna structures based upon the height or location, including proximity to airports. Proposals to construct or to modify existing tower or antenna structures above certain heights are reviewed by the FAA to ensure the
structure will not present a hazard to aviation, which determination may be conditioned upon compliance with lighting or marking requirements. The FCC requires its licensees to operate communications devices only on towers
that comply with FAA rules and are registered with the FCC, if required by its regulations. Where tower lighting is required by FAA regulation, tower owners bear the responsibility of notifying the FAA of any tower lighting
outage and ensuring the timely restoration of such outages.

State and Local Regulations. The U.S. Telecommunications Act of 1996 amended the Communications Act of 1934 to preserve state and local zoning authorities' jurisdiction over the siting of communications towers and
small cells. The law, however, limits state and local zoning authority by prohibiting actions by such authorities that discriminate between different service providers of wireless communications or prohibit altogether (actually or
effectively) the provision of wireless communications. Additionally, the law prohibits state and local restrictions based on the environmental effects of radio frequency emissions to the extent the facilities comply with FCC
regulations.

Local regulations include city and other local ordinances (including subdivision and zoning ordinances), approvals for construction, modification and removal of towers and small cells, and restrictive covenants imposed
by community developers. These regulations vary greatly, but typically require us to obtain prior approval from local officials. Local zoning authorities may render decisions that prevent the construction or modification of
towers or small cells, or place conditions on such construction or modifications that are responsive to community residents' concerns regarding the height, visibility, or other characteristics of such infrastructure. Over the last
several years, the FCC has adopted regulations and 30 states have passed legislation intended to expedite and streamline the deployment of wireless networks, including establishing presumptively reasonable timeframes for
reviews by local and state governments. Notwithstanding such developments, decisions of local regulatory authorities and utilities in certain jurisdictions may continue to adversely affect deployment timing and cost.

Certain of our subsidiaries hold state authorizations, including authorizations to act as competitive local exchange carriers ("CLECs"), to provide intrastate telecommunication services in addition to FCC authorization to
provide domestic interstate telecommunication services. State authorizations may help promote access to public rights-of-way, which is beneficial to the timely deployment of fiber and small cells, and often allow us to deploy
such infrastructure in locations where zoning restrictions might otherwise delay, restrict, or prevent building or expanding traditional wireless tower and rooftop sites. See "Item 1A. Risk Factors" for additional information
regarding rights to our infrastructure.

Environmental. We are required to comply with a variety of federal, state and local environmental laws and regulations protecting environmental quality, including air and water quality, and wildlife. To date, we have not
incurred any material fines or penalties or experienced any material adverse effects to our business as a result of any domestic or international environmental regulations or matters. See "Item 1A. Risk Factors" for additional
information regarding compliance with laws and regulations.

The construction of new towers and small cells or, in some cases, their modification in the U.S. may be subject to environmental review under the National Environmental Policy Act of 1969, as amended ("NEPA"), which
requires federal agencies to evaluate the environmental impact of major federal actions. NEPA regulations require applicants to investigate the potential environmental impact of the proposed tower or small cells construction. If
the FCC determines that the proposed tower or small cells construction or modification presents a significant environmental impact, the FCC is required to prepare an environmental impact statement, which is subject to public
comment. Such determination could significantly delay the FCC's approval of the construction or modification.

11

Our  operations  are  also  subject  to  federal,  state  and  local  laws  and  regulations  relating  to  the  management,  use,  storage,  disposal,  emission,  or  remediation  of,  or  exposure  to,  hazardous  or  non-hazardous  substances,
materials, or wastes. As an owner, lessee, or operator of real property, we are subject to certain environmental laws that impose strict, joint-and-several liability for the cleanup of on-site or off-site contamination relating to
existing or historical operations; or we could also be subject to personal injury or property damage claims relating to such contamination. In general, our tenant contracts prohibit our tenants from using or storing any hazardous
substances on our communications infrastructure sites in violation of applicable environmental laws and require our tenants to provide notice of certain environmental conditions caused by them.

We are subject to Occupational Safety and Health Administration and similar guidelines regarding employee protection from radio frequency exposure. In recent years, the scientific community has extensively studied

low-level radio frequency emissions to determine whether they have any connection to certain negative health effects, such as cancer.

We have compliance programs and monitoring projects designed to promote compliance with applicable environmental laws and regulations. Nevertheless, there can be no assurance that the costs of compliance with

existing or future environmental laws will not have a material adverse effect on us.

Item 1A.     Risk Factors

You should carefully consider all of the risks described below, as well as the other information contained in this document, when evaluating your investment in our securities.

Risks Relating to Our Business and Industry

Our business depends on the demand for our communications infrastructure, driven primarily by demand for data, and we may be adversely affected by any slowdown in such demand. Additionally, a reduction in the
amount or change in the mix of network investment by our tenants may materially and adversely affect our business (including reducing demand for our communications infrastructure or services).

Tenant demand for our communications infrastructure depends on consumers' and organizations' demand for data. Additionally, the willingness of our tenants to utilize our communications infrastructure, or renew or

extend existing tenant contracts on our communications infrastructure, is affected by numerous factors, including:

•
•
•
•
•
•
•
•
•
•
•
•
•

•

availability or capacity of our communications infrastructure or associated land interests;
location of our communications infrastructure;
financial condition of our tenants, including their profitability and availability or cost of capital;
willingness of our tenants to maintain or increase their network investment or changes in their capital allocation strategy;
need for integrated networks and organizations;
availability and cost of spectrum for commercial use;
increased use of network sharing, roaming, joint development, or resale agreements by our tenants;
mergers or consolidations by and among our tenants;
changes in, or success of, our tenants' business models;
governmental regulations and initiatives, including local or state restrictions on the proliferation of communications infrastructure;
cost of constructing communications infrastructure;
our market competition, including tenants that may elect to self-perform;
technological changes, including those (1) affecting the number or type of communications infrastructure needed to provide data to a given geographic area or which may otherwise serve as a substitute or alternative
to our communications infrastructure or (2) resulting in the obsolescence or decommissioning of certain existing wireless networks; and
our ability to efficiently satisfy our tenants' service requirements.

A slowdown in demand for data or our communications infrastructure may negatively impact our growth or otherwise have a material adverse effect on us. If our tenants or potential tenants are unable to raise adequate
capital  to  fund  their  business  plans,  as  a  result  of  disruptions  in  the  financial  and  credit  markets  or  otherwise,  they  may  reduce  their  spending,  which  could  adversely  affect  our  anticipated  growth  or  the  demand  for  our
communications infrastructure or services.

The amount, timing, and mix of our tenants' network investment is variable and can be significantly impacted by the various matters described in these risk factors. Changes in tenant network investment typically impact
the demand for our communications infrastructure. As a result, changes in tenant plans such as delays in the implementation of new systems, new and emerging technologies (including small cells and fiber solutions), or plans to
expand coverage or capacity may reduce demand for our communications infrastructure. Furthermore, the industries in which our tenants operate (particularly those in the wireless industry) could experience a slowdown or
slowing growth rates as a result of numerous factors, including a reduction in consumer demand for data or general economic conditions. There can be no assurances that weakness or uncertainty in the economic environment
will not adversely impact our tenants or their industries, which may materially and adversely affect our business, including by reducing demand for our communications infrastructure or services. In addition, a slowdown may
increase competition for site rental tenants or services. Such an industry slowdown or a reduction in tenant network investment may materially and adversely affect our business.

13

A substantial portion of our revenues is derived from a small number of tenants, and the loss, consolidation or financial instability of any of such tenants may materially decrease revenues or reduce demand for our
communications infrastructure and services.

Our three largest tenants are T-Mobile , AT&T and Verizon Wireless. The loss of any one of our largest tenants as a result of consolidation, merger, bankruptcy, insolvency, network sharing, roaming, joint development,
resale agreements by our tenants or otherwise may result in (1) a material decrease in our revenues, (2) uncollectible account receivables, (3) an impairment of our deferred site rental receivables, communications infrastructure
assets, or intangible assets (including goodwill), or (4) other adverse effects to our business. We cannot guarantee that tenant contracts with our largest tenants will not be terminated or that these tenants will renew their tenant
contracts with us. In addition to our three largest tenants, we also derive a portion of our revenues and anticipated future growth from (1) fiber solutions tenants and (2) new entrants offering or contemplating offering wireless
services. Such tenants (including those dependent on government funding) may be smaller or have less financial resources than our three largest tenants, may have business models which may not be successful, or may require
additional capital.

Consolidation among our tenants will likely result in duplicate or overlapping parts of networks, for example, where they are co-residents on a tower or small cell network, which may result in the termination, non-renewal
or re-negotiation of tenant contracts and negatively impact revenues from our communications infrastructure. Due to the long-term nature of our tenant contracts, we generally expect that the impact to our site rental revenues
from any termination of our tenant contracts as a result of such potential consolidation would be spread over multiple years. Such consolidation (or potential consolidation) may result in a reduction or slowdown in such tenants'
network investment in the aggregate because their expansion plans may be similar. Tenant consolidation could decrease the demand for our communications infrastructure and services, which in turn may result in a reduction in
our revenues or cash flows and may trigger a review for impairment of certain long-lived assets.

On January 6, 2022, we entered into the T-Mobile Agreement. We anticipate that the T-Mobile and Sprint network consolidation contemplated in the T-Mobile Agreement will result in higher Towers non-renewals in 2025,
which are expected to reduce site rental revenues by approximately $200 million. Except for full year 2025, we expect our annual Towers non-renewals to remain in line with our historical range of 1% to 2% of annual site rental
revenues. Additionally, we anticipate that the T-Mobile and Sprint network consolidation will result in small cell non-renewals, which are expected to reduce site rental revenues by approximately $45 million, with the majority
occurring in 2023. Except for full year 2023, we expect consolidated annual small cell non-renewals to remain in line with the our historical range of 1% to 2% of annual site rental revenues.

See "Item 1. Business—The Company" and note 14 to our consolidated financial statements for further information regarding our largest tenants.

The expansion or development of our business, including through acquisitions, increased product offerings or other strategic growth opportunities, may cause disruptions in our business, which may have an adverse effect
on our business, operations or financial results.

We seek to expand and develop our business, including through acquisitions, increased product offerings (such as small cells and fiber solutions), or other strategic growth opportunities. In the ordinary course of our
business, we review, analyze and evaluate various potential transactions or other activities in which we may engage. Such transactions or activities could be a complex, costly, time-consuming process, or cause disruptions in,
increase risk or otherwise negatively impact our business. Among other things, such transactions and activities may:

•
•
•
•
•
•
•

•

disrupt our business relationships with our tenants, depending on the nature of or counterparty to such transactions and activities;
divert capital and the time or attention of management away from other business operations, including as a result of post-transaction integration activities;
fail to achieve revenue or margin targets, operational synergies or other benefits contemplated;
increase operational risk or volatility in our business;
not result in the benefits management had expected to realize from such expansion and development activities, or those benefits may take longer to realize than expected;
impact our cost structure and result in the need to hire additional employees;
increase  demands  on  current  employees  or  result  in  current  or  prospective  employees  experiencing  uncertainty  about  their  future  roles  with  us,  which  might  adversely  affect  our  ability  to  retain  or  attract  key
employees; or
result in the need for additional TRSs or contributions of certain assets to TRSs, which are subject to federal and state corporate income taxes.

14

Our Fiber segment has expanded rapidly, and the Fiber business model contains certain differences from our Towers business model, resulting in different operational risks. If we do not successfully operate our Fiber
business model or identify or manage the related operational risks, such operations may produce results that are lower than anticipated.

In recent years, we have allocated a significant amount of capital to our Fiber business, which is a much less mature business for us than our Towers business. Our Fiber segment represented 33% and 34% of our site rental
revenues for the years ended December 31, 2021 and 2020, respectively. The business model for our Fiber operations contains certain differences from our business model for our Towers operations, including certain differences
relating to tenant base, competition, contract terms (including requirements for service level agreements regarding network performance and maintenance), upfront capital requirements, landlord demographics, deployment and
ownership of certain network assets, operational oversight requirements, government regulations, growth rates and applicable laws.

While our Fiber operations have certain risks that are similar to our Towers operations, they also have certain operational risks (including the scalability of processes) that are different from our Towers business, including:

•
•
•
•
•
•
•
•
•
•
•
•
•
•

the use of public rights-of-way and franchise agreements;
the use of poles and conduits owned solely by, or jointly with, third parties;
risks relating to overbuilding;
risks relating to the specific markets in which we choose or plan to operate;
risks relating to construction hazards, including boring, trenching, utility and maintenance of traffic hazards;
construction management and construction-related billings to tenants;
risks relating to wireless carriers building their own small cell networks, or tenants utilizing their own or alternative fiber assets;
the risk of failing to optimize the use of our finite supply of fiber strands;
damage to our assets and the need to maintain, repair, upgrade and periodically replace our assets;
the risk of failing to properly maintain or operate highly specialized hardware and software;
network data security risks;
the risk of new technologies that could enable tenants to realize the same benefits with less utilization of our fiber;
potential damage to our overall reputation as a communications infrastructure provider; and
the use of CLEC status.

In addition, the rate at which tenants adopt or prioritize small cells and fiber solutions may be lower or slower than we anticipate or may cease to exist altogether. For example, our tenants have initially focused on utilizing
towers in the first phase of deploying their 5G networks, which has led to delays in some of our small cell deployments. We anticipate that these delays will be temporary, as our tenants plan for the next phase of their 5G
network deployment which we believe will require small cells at scale. Our Fiber operations will also expose us to different safety or liability risks or hazards than our Towers business as a result of numerous factors, including
those stemming from the deployment, location or nature of the assets involved. There may be risks and challenges associated with small cells and fiber solutions being comparatively new and emerging technologies that are
continuing to evolve, and there may be other risks related to small cells and fiber solutions of which we are not yet aware.

Failure to timely, efficiently and safely execute on our construction projects could adversely affect our business.

Our construction projects and related contracts can be long-term, complex in nature, dangerous, costly and challenging to execute. The quality of our performance on such construction projects depends in large part upon
our ability to manage (1) the associated tenant relationship and (2) the project itself by timely deploying and properly managing appropriate internal and external project resources.  In connection with our construction projects,
we generally bear the risk of cost over-runs, labor availability and productivity, and contractor pricing and performance.  

In addition, the construction projects (including modifications of existing infrastructure) can pose certain safety risks, including:

•
•
•
•

risks resulting from elevated work, including falling hazards;
risks of third-party non-compliance with safety regulations, industry best practices or other applicable standards;
risks associated with utility hazards, including gas line, electrical or sewage strikes, which may result in explosions, electrocution and other potentially catastrophic events; and
risk of potential wildfires, including due to welding, grinding, cutting or other construction activity.

Such safety risks may cause personal injury or loss of life, severe damage to or destruction of property, suspension of operations or services, or significant damage to the environment, creating financial, regulatory or

reputational damage that could adversely affect our business. See "Our business may be adversely impacted by climate-related events, natural disasters,

15

including wildfires, and other unforeseen events" below for additional information regarding potential adverse impacts to our business which may result from wildfires and other climate-related events.

Further, investments in newly constructed communications infrastructure may result in lower initial returns compared to returns on our existing communications infrastructure or us not being able to realize future tenant
additions at anticipated levels. Additionally, contracts with our tenants for these projects typically specify delivery dates, performance criteria and penalties for our failure to perform.  On occasion, we experience unforeseen
delays from municipalities and utility companies that result in longer construction timelines than expected, which impact our ability to timely deliver on our projects. We may also experience unforeseen delays as a result of
supply chain disruptions and labor shortages. Our  failure  to  manage  such  tenant  relationships,  project  resources,  and  project  milestones  in  a  timely  and  efficient  manner  and  appropriately  manage  safety  risks  could  have  a
material adverse effect on our business.

New technologies may reduce demand for our communications infrastructure or negatively impact our revenues.

Improvements in the efficiency, architecture, and design of communication networks may reduce the demand for our communications infrastructure. For example, new technologies and spectrum that may promote network
sharing, joint development, backhaul and fronthaul efficiency or resale agreements by our tenants, such as signal combining technologies or network virtualization, may reduce the need for our communications infrastructure. In
addition, other technologies, such as WiFi, Distributed Antenna Systems ("DAS"), other small cells, blimps, satellite (such as low earth orbiting) and mesh transmission systems may, in the future, serve as substitutes for, or
alternatives  to,  leasing  on  communications  infrastructure  that  might  otherwise  be  anticipated  or  expected  had  such  technologies  not  existed.  In  addition,  new  technologies  that  enhance  the  range,  efficiency  and  capacity  of
communication equipment could reduce demand for our communications infrastructure. Any significant reduction in demand for our communications infrastructure resulting from the new technologies may negatively impact
our revenues or otherwise have a material adverse effect on us.

If we fail to retain rights to our communications infrastructure, including the rights to land under our towers and the right-of-way and other agreements related to our small cells and fiber, our business may be adversely
affected.

The property interests and other rights to our communications infrastructure, including the land under our towers, are derived from leasehold and sub-leasehold interests, fee interests, easements, licenses, rights-of-way,
and franchise and other agreements. A loss of these interests and other rights may interfere with our ability to conduct our business or generate revenues. For various reasons, we may not always have the ability to access,
analyze, or verify all information regarding titles or other issues prior to acquiring communications infrastructure. Further, we may not be able to renew ground leases or other agreements on commercially viable terms.

Our ability to retain rights to the land on which our towers are located depends on our ability to purchase such land, by acquiring fee interests and perpetual easements, or renegotiate or extend the terms of the agreements
relating to such land. Approximately 10% of our Towers site rental gross margin for the year ended December 31, 2021 was derived from towers where the leases for the land under such towers had final expiration dates of less
than 10 years. If we are unable to retain rights to the property on which our communications infrastructure is located, our business may be adversely affected.

As  of  December  31,  2021,  approximately  53%  of  our  towers  were  leased  or  subleased  or  operated  and  managed  under  master  leases,  subleases,  or  other  agreements  with  AT&T  and  T-Mobile  (including  agreements
assumed by T-Mobile in connection with its merger with Sprint). We have the option to purchase these towers at the end of their respective lease terms. We have no obligation to exercise such purchase options. We may not have
the required available capital to exercise our right to purchase some or all of these towers at the time these options are exercisable. Even if we do have available capital, we may choose not to exercise our right to purchase these
towers or some or all of the T-Mobile or AT&T towers for business or other reasons. In the event that we do not exercise these purchase rights, or are otherwise unable to acquire an interest that would allow us to continue to
operate these towers after the applicable period, we will lose the cash flows derived from such towers, which may have a material adverse effect on our business. In the event that we decide to exercise these purchase rights, the
benefits of the acquisition of these towers may not exceed the costs, which could adversely affect our business. Additional information concerning these towers and the applicable purchase options as of December 31, 2021 is as
follows:

•

•

22% of our towers are leased or subleased or operated and managed under a master prepaid lease or other related agreements with AT&T for a weighted-average initial term of approximately 28 years, weighted on
Towers site rental gross margin. We have the option to purchase the leased and subleased towers from AT&T at the end of the respective lease or sublease terms for aggregate option payments of approximately $4.2
billion, which payments, if such option is exercised, would be due between 2032 and 2048.

16% of our towers are leased or subleased or operated and managed for an initial period of 32 years (through May 2037) under master leases, subleases or other agreements with T-Mobile (which T-Mobile assumed
in connection

16

with its merger with Sprint). We  have  the  option  to  purchase  in  2037  all  (but  not  less  than  all)  of  the  leased  and  subleased  towers  from  T-Mobile  for  approximately  $2.3  billion.15%  of  our  towers  are  leased  or
subleased or operated and managed under a master prepaid lease or other related agreements with T-Mobile for a weighted-average initial term of approximately 28 years, weighted on Towers site rental gross margin.
We have the option to purchase the leased and subleased towers from T-Mobile at the end of the respective lease or sublease terms for aggregate option payments of approximately $2.0 billion, which payments, if
such option is exercised, would be due between 2035 and 2049. In addition, through the T-Mobile Acquisition, another 1% of our towers are subject to a lease and sublease or other related arrangements with AT&T.
We have the option to purchase these towers that we do not otherwise already own at the end of their respective lease terms for aggregate option payments of up to approximately $405 million, which payments, if
such option is exercised, would be due prior to 2032 (less than $10 million would be due before 2025).

Under master lease or master prepaid lease arrangements we have with AT&T and T-Mobile, including agreements assumed by T-Mobile in connection with its merger with Sprint, certain of our subsidiaries lease or
sublease, or are otherwise granted the right to manage and operate, towers from bankruptcy remote subsidiaries of such carriers. If one of these bankruptcy remote subsidiaries should become a debtor in a bankruptcy proceeding
and is permitted to reject the underlying ground lease, our subsidiaries could lose their interest in the applicable sites. If our subsidiaries were to lose their interest in the applicable sites or if the applicable ground leases were to
be terminated, we would lose the cash flow derived from the towers on those sites, which may have a material adverse effect on our business. We have similar bankruptcy risks with respect to sites that we operate under
management agreements.

For our small cells and fiber, we must maintain rights-of-way, franchise, pole attachment, conduit use, fiber use and other agreements to operate our assets. For various reasons, we may not always have the ability to
maintain these agreements or obtain future agreements to construct, maintain and operate our fiber assets. Access to rights-of-way may depend on our CLEC status, and we cannot be certain that jurisdictions will (1) recognize
such CLEC status or (2) not change their laws concerning CLEC access to rights-of-way. If a material portion of these agreements are terminated or are not renewed, we might be forced to abandon our assets, which may
adversely impact our business. In order to operate our assets, we must also maintain fiber agreements that we have with public and private entities. There is no assurance that we will be able to renew these agreements on
favorable terms, or at all. If we are unable to renew these agreements on favorable terms, we may face increased costs or reduced revenues.

Additionally, in order to expand our communications infrastructure footprint to new locations, we often need to obtain new or additional rights-of-way and other agreements. Our failure to obtain these agreements in a

prompt and cost-effective manner may prevent us from expanding our footprint, which may be necessary to meet our contractual obligations to our tenants and could adversely impact our business.

Our services business has historically experienced significant volatility in demand, which reduces the predictability of our results.

The operating results of our services business for any particular period may experience significant fluctuations given its non-recurring nature and should not necessarily be considered indicative of longer-term results for

this activity. Our services business is generally driven by demand for our communications infrastructure and may be adversely impacted by various factors, including:

•
•
•
•
•
•
•
•

competition;
the timing, mix and amount of tenant network investments;
the rate and volume of tenant deployment plans;
unforeseen delays or challenges relating to work performed;
economic weakness or uncertainty;
labor availability and productivity;
our market share; and
changes in the size, scope, or volume of work performed.

If radio frequency emissions from wireless handsets or equipment on our communications infrastructure are demonstrated to cause negative health effects, potential future claims could adversely affect our operations,
costs or revenues.

The potential connection between radio frequency emissions and certain negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent years. We

cannot guarantee that claims relating to radio frequency emissions will not arise in the future or that the results of such studies will not be adverse to us.

17

Public perception of possible health risks associated with cellular or other wireless connectivity services and wireless technologies (such as 5G) may slow or diminish the growth of wireless companies and deployment of
new wireless technologies, which may in turn slow or diminish our growth. In particular, negative public perception of, and regulations regarding, these perceived health risks may slow or diminish the market acceptance of
wireless services and technologies. If a connection between radio frequency emissions and possible negative health effects were established, our operations, costs, or revenues may be materially and adversely affected. We
currently do not maintain any significant insurance with respect to these matters.

Cybersecurity breaches or other information technology disruptions could adversely affect our operations, business, and reputation.

Despite  existing  security  measures,  certain  of  our  communications  infrastructure  may  be  subject  to  damage,  disruptions,  or  shutdowns  due  to  unauthorized  access,  computer  viruses,  ransomware  or  other  malicious
software, cyber-attacks and other security breaches. An attack attempt or security breach, such as a distributed denial of service attack, could potentially result in (1) interruption or cessation of certain of our services to our
tenants, (2) our inability to meet expected levels of service to our tenants, (3) data transmitted over our tenants' networks being compromised or misappropriated, or (4) business or other sensitive data being compromised or
misappropriated. Although we believe we have a comprehensive incident response plan and other cybersecurity measures and policies in place, we cannot guarantee that our security measures will not be circumvented, resulting
in  tenant  network  failures  or  interruptions  that  could  impact  our  tenants'  network  availability  and  have  a  material  adverse  effect  on  our  business,  financial  condition,  or  operational  results.  Additionally,  security  incidents
impacting our tenants, vendors and business partners could result in a material adverse effect on our business. We may be required to expend significant resources to protect against or recover from such threats. If an actual or
perceived breach of our cybersecurity or information technology occurs, the market perception of the effectiveness of our security measures could be harmed, and we could lose tenants. Further, the perpetrators of cyber-attacks
are not restricted to particular groups or persons. These attacks may be committed by our employees or external actors operating in any geography. In addition, our acquisitions, both past and future, may alter our potential
exposure to the risks described above. While we maintain insurance that includes coverage in the event of cybersecurity or other information technology breaches, there can be no assurances that such coverage will be adequate
to cover exposure from such incidents.

Our business may be adversely impacted by climate-related events, natural disasters, including wildfires, and other unforeseen events.

We could be negatively impacted by other unforeseen events, such as extreme weather events or natural disasters (including as a result of any potential effects of climate change), or acts of vandalism. There is increasing
concern that global climate change is occurring and could result in increased frequency of certain types of natural disasters and extreme weather events. Although we have implemented a wildfire risk mitigation program, the
effects of climate change have increased the risk and extent of wildfires that could potentially result from certain of our construction and maintenance projects and other operating activities. We cannot predict with certainty the
rate at which climate change is occurring or the potential direct or indirect impacts of climate change to our business. Any such unforeseen events could, among other things, damage or delay deployment of our communications
infrastructure,  interrupt  or  delay  service  to  our  tenants  or  could  result  in  legal  claims  or  penalties,  disruption  in  operations,  damage  to  our  reputation,  negative  market  perception,  or  costly  response  measures,  which  could
adversely affect our business.

While we currently maintain insurance policies that include coverage in the event of natural disasters and other unforeseen events, including possible incidents in which our actions (or the actions of those acting on our
behalf) contribute to such events, there can be no assurances that such coverage will be adequate to cover exposure from such events. Further, we do not maintain, and do not expect to maintain, insurance policies that provide
adequate coverage in the event that our actions (or those actions of those acting on our behalf) contribute to a wildfire event, as a result of the fact that such insurance policies are generally not economically available.

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

The global outbreak of COVID-19 has adversely affected the U.S. 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"), including the imposition of travel restrictions, quarantine or "shelter-in-place" requirements, the promotion of social distancing, vaccination requirements 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, and may continue to lead to, business and global supply chain disruptions and volatility in the global capital
markets. 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.

18

We do not believe that COVID-19 had a material impact on our financial position, results of operations and cash flows for the year ended December 31, 2021. The extent to which the COVID-19 pandemic will affect our
business, financial position, results of operations and cash flows in the future is difficult to predict with certainty and depends on numerous evolving factors, including: the duration, scope and severity of the pandemic; the
effectiveness of the COVID-19 vaccine in curbing the spread of the virus; the vaccination rates and the impact of the vaccine and testing mandates; government, social, business and other actions that have been and will be taken
in response to the pandemic, including with respect to mandatory vaccinations; 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 availability of our suppliers and vendors or their ability to provide products and services 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; (4) increase our cost of capital and adversely impact our access to capital; and (5)
result in difficulty fulfilling our labor needs. Due to 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 or others take in response thereto on our business, financial position, results of operations and
cash flows, particularly over the near- to medium-term, but the impact could be material. See "Item 7. MD&A—General Overview—COVID-19" for further information.

As a result of competition in our industry, we may find it more difficult to negotiate favorable rates on our new or renewing tenant contracts.

Our growth is dependent on our entering into new tenant contracts (including amendments to tenant contracts upon modification of an existing tower, fiber, or small cell installation), as well as renewing or renegotiating
tenant contracts when existing tenant contracts terminate. Competition in our industry may make it more difficult for us to attract new tenants, maintain or increase our gross margins, or maintain or increase our market share. In
addition, competition (primarily in our fiber solutions business) may, in certain circumstances, cause us to renegotiate certain existing tenant contracts to avoid early contract terminations. We face competition for site rental
tenants and associated contractual rates from various sources, including (1) other independent communications infrastructure owners or operators, including those that own, operate, or manage towers, rooftops, broadcast or
transmission towers, utility poles, fiber (including non-traditional competitors such as cable providers) or small cells, or (2) new alternative deployment methods for communications infrastructure.

Our  Fiber  business  generally  has  different  competitors  than  those  in  our  Towers  business,  including  other  owners  of  fiber,  as  well  as  new  entrants  into  small  cells  and  fiber  solutions,  some  of  which  may  have  larger

networks, greater financial resources or more experience in managing such assets than we have.

New wireless technologies may not deploy or be adopted by tenants as rapidly or in the manner projected.

There can be no assurances that new wireless services or technologies, which may drive demand for our communications infrastructure, will be introduced or deployed as rapidly or in the manner projected by the wireless
carriers. In addition, demand or tenant adoption rates for such new technologies may be lower or slower than anticipated for numerous reasons. As a result, growth opportunities or demand for our communications infrastructure
arising from such technologies may not be realized at the times or to the extent anticipated.

Risks Related to Our Debt and Equity

Our substantial level of indebtedness could adversely affect our ability to react to changes in our business, and the terms of our debt instruments limit our ability to take a number of actions that our management might
otherwise believe to be in our best interests. In addition, if we fail to comply with our covenants, our debt could be accelerated.

We have a substantial amount of indebtedness (approximately $20.7 billion as of February 18, 2022). See "Item 7. MD&A—Liquidity and Capital Resources" for a tabular presentation of our contractual debt maturities. As

a result of our substantial indebtedness:

•
•
•

•
•
•

we may be more vulnerable to general adverse economic or industry conditions;
we may find it more difficult to obtain additional financing to fund discretionary investments or other general corporate requirements or to refinance our existing indebtedness;
we are or will be required to dedicate a substantial portion of our cash flows from operations to the payment of principal or interest on our debt, thereby reducing the available cash flows to fund other projects,
including the discretionary investments discussed in "Item 1. Business" and "Item 7. MD&A—Liquidity and Capital Resources";
we may have limited flexibility in planning for, or reacting to, changes in our business or in the industry;
we may have a competitive disadvantage relative to other companies in our industry with less debt;
we may be adversely impacted by changes in interest rates;

19

•
•
•
•

we may be adversely impacted by changes to credit ratings related to our debt instruments;
we may be required to issue equity securities or securities convertible into equity or sell some of our assets, possibly on unfavorable terms, in order to meet payment obligations;
we may be limited in our ability to take advantage of strategic business opportunities, including communications infrastructure development or mergers and acquisitions; and
we could fail to remain qualified for taxation as a REIT due to limitations on our ability to declare and pay dividends to stockholders as a result of restrictive covenants in our debt instruments.

Currently we have debt instruments in place that limit in certain circumstances our ability to incur additional indebtedness, pay dividends, create liens, sell assets, or engage in certain mergers and acquisitions, among other
things.  In  addition,  the  credit  agreement  ("Credit  Agreement")  governing  our  senior  unsecured  credit  facility,  which  consists  of  our  senior  unsecured  term  loan  A  facility  and  senior  unsecured  revolving  credit  facility
(collectively, "2016 Credit Facility"), contains financial maintenance covenants. Our ability to comply with these covenants or to satisfy our debt obligations will depend on our future operating performance. If we violate the
restrictions in our debt instruments or fail to comply with our financial maintenance covenants, we will be in default under those instruments, which in some cases would cause the maturity of a substantial portion of our long-
term indebtedness to be accelerated. Furthermore, if the limits on our ability to pay dividends prevent us from satisfying our REIT distribution requirements, we could fail to remain qualified for taxation as a REIT. If these
limits do not jeopardize our qualification for taxation as a REIT but nevertheless prevent us from distributing 100% of our REIT taxable income, we will be subject to federal and state corporate income taxes, and potentially a
nondeductible excise tax, on our undistributed taxable income. If our operating subsidiaries were to default on their debt, the trustee could seek to foreclose the collateral securing such debt, in which case we could lose the
communications infrastructure and the associated revenues. See "Item 7. MD&A—Liquidity and Capital Resources—Debt Covenants" for a further discussion of our debt covenants.

CCIC  is  a  holding  company  that  conducts  all  of  its  operations  through  its  subsidiaries.  Accordingly,  CCIC's  sources  of  cash  to  pay  interest  or  principal  on  its  outstanding  indebtedness  are  distributions  relating  to  its
respective ownership interests in its subsidiaries from the net earnings and cash flows generated by such subsidiaries or from proceeds of debt or equity offerings. Earnings and cash flows generated by CCIC's subsidiaries are
first applied by such subsidiaries to conduct their operations, including servicing their respective debt obligations, after which any excess cash flows generally may be paid to CCIC, in the absence of any special conditions, such
as a continuing event of default. However, CCIC's subsidiaries are legally distinct from the holding company and, unless they guarantee such debt, have no obligation to pay amounts due on their debt or to make funds available
to us for such payment.

We  have  a  substantial  amount  of  indebtedness.  In  the  event  we  do  not  repay  or  refinance  such  indebtedness,  we  could  face  substantial  liquidity  issues  and  might  be  required  to  issue  equity  securities  or  securities
convertible into equity securities, or sell some of our assets to meet our debt payment obligations.

We have a substantial amount of indebtedness, which, upon final maturity, we will need to refinance or repay. See "Item 7. MD&A—Liquidity and Capital Resources" for a tabular presentation of our contractual debt

maturities. There can be no assurances we will be able to refinance our indebtedness (1) on commercially reasonable terms, (2) on terms, including with respect to interest rates, as favorable as our current debt, or (3) at all.

Economic conditions and the credit markets have historically experienced, and may continue to experience, periods of volatility, uncertainty, or weakness that could impact (1) the availability or cost of debt financing,
including any refinancing of the obligations described above, (2) our ability to draw the full amount of our $5.0 billion senior unsecured revolving credit facility under our 2016 Credit Facility ("2016 Revolver"), that, as of
February 18, 2022, has $5.0 billion of undrawn availability, or (3) our ability to issue the full amount of the $1.0 billion commercial paper notes ("Commercial Paper Notes") under our unsecured commercial paper program
("CP Program"), that, as of February 18, 2022, had $866 million outstanding.

Borrowings under our 2016 Credit Facility generally bear an interest rate based on LIBOR per annum plus a credit spread based on our senior unsecured credit rating. In July 2017, the United Kingdom's Financial Conduct
Authority ("FCA"), which regulates LIBOR, announced that, after 2021, it will stop compelling banks to submit rates for the calculation of LIBOR. In March 2021, the administrator of LIBOR announced its intention to cease
the publication of (1) all non-U.S. dollar LIBOR settings and the one-week and two-month U.S. dollar LIBOR settings on December 31, 2021, and (2) the remaining U.S. dollar LIBOR settings after June 30, 2023. Further, the
use of U.S. dollar LIBOR will not be allowed in most new contracts entered into after December 31, 2021. Our Credit Agreement includes "hardwired" LIBOR transition provisions consistent with those published by the
Alternative  Reference  Rate  Committee  ("ARRC").  Although  the  ARRC  has  identified  the  Secured  Overnight  Financing  Rate  ("SOFR")  as  the  recommended  alternative  rate  for  U.S.  dollar  LIBOR  and  has  formally
recommended the CME Group's forward-looking SOFR term rates, there is not yet a generally accepted methodology for adjusting SOFR. While interest rates on our 2016 Credit Facility were not impacted by the LIBOR
settings that ceased publication on December 31, 2021, we are evaluating the potential impact of the LIBOR replacement, including in the event of any amendment to our 2016

20

Credit Facility, and we cannot predict with certainty what such replacement rate would be, what other reforms could be implemented in the future, or the potential effect of these changes and the establishment of alternative
reference rates on our business. The discontinuation, reform or replacement of LIBOR could result in interest rate increases on our 2016 Credit Facility, which could adversely affect our cash flows and operating results.

If we are unable to repay or refinance our debt, we cannot guarantee that we will be able to generate enough cash flows from operations or that we will be able to obtain enough capital to service our debt, fund our planned
capital expenditures or pay future dividends. In such an event, we could face substantial liquidity issues and might be required to issue equity securities or securities convertible into equity securities, or sell some of our assets to
meet our debt payment obligations. Failure to repay or refinance indebtedness when required could result in a default under such indebtedness. If we incur additional indebtedness, any such indebtedness could exacerbate the
risks described above.

Sales or issuances of a substantial number of shares of our common stock or securities convertible into shares of our common stock may adversely affect the market price of our common stock.

Future sales or issuances of common stock or other equity related securities may adversely affect the market price of our common stock, including any shares of our common stock issued to finance capital expenditures,
finance acquisitions or repay debt. Our business strategy contemplates access to external financing to fund certain discretionary investments, which may include issuances of common stock or other equity related securities. We
maintain an "at-the-market" stock offering program ("2021 ATM Program") through which we may, from time to time, issue and sell shares of our common stock having an aggregate gross sales price of up to $750 million to or
through sales agents. As of February 18, 2022, we had approximately $750 million of gross sales of common stock remaining under our 2021 ATM Program. From time to time, we may refresh or implement a new "at-the-
market" stock offering program. See note 10 to our consolidated financial statements. As of February 18, 2022, we had approximately 432 million shares of common stock outstanding.

We have reserved approximately 7 million of common stock for issuance in connection with awards granted under our stock compensation plan.

Further, a small number of common stockholders own a significant percentage of our outstanding common stock. If any one of these common stockholders, or any group of our common stockholders, sells a large quantity

of shares of our common stock, or the public market perceives that existing common stockholders might sell a large quantity of shares of our common stock, the market price of our common stock may significantly decline.

Certain  provisions  of  our  restated  certificate  of  incorporation  ("Charter"),  amended  and  restated  by-laws  ("By-laws")  and  operative  agreements,  and  domestic  and  international  competition  laws  may  make  it  more
difficult for a third party to acquire control of us or for us to acquire control of a third party, even if such a change in control would be beneficial to our stockholders.

We have a number of anti-takeover devices in place that will hinder takeover attempts or may reduce the market value of our common stock. Our anti-takeover provisions include:

•
•
•

the authority of the board of directors to issue preferred stock without approval of the holders of our common stock;
advance notice and other procedural requirements relating to director nominations or proposals submitted by stockholders for actions to be taken at annual meetings; and
provisions that the state courts or, in certain circumstances, the federal courts, in Delaware shall be the sole and exclusive forum for certain actions involving us, our directors, officers, employees and stockholders,
and, unless the Company otherwise consents, that the federal courts shall be the sole and exclusive forum for resolution of claims arising under the Securities Act of 1933, as amended (“Securities Act”). Since the
Securities Act provides that federal and state courts have concurrent jurisdiction over lawsuits brought pursuant to the Securities Act, there may be uncertainty as to whether a court would enforce such a provision.
Stockholders will not be deemed to have waived compliance with the federal securities laws, and this provision does not apply to claims for which the federal courts have exclusive jurisdiction (such as under the
Exchange Act).

Our By-laws permit special meetings of the stockholders to be called only upon the request of our Chief Executive Officer or a majority of the board of directors, and deny stockholders the ability to call such meetings.
Such provisions, as well as the provisions of Section 203 of the Delaware General Corporation Law, may impede a merger, consolidation, takeover, or other business combination or discourage a potential acquirer from making
a tender offer or otherwise attempting to obtain control of us.

21

In  addition,  domestic  or  international  competition  laws  may  prevent  or  discourage  us  from  acquiring  communications  infrastructure  in  certain  geographical  areas  or  impede  a  merger,  consolidation,  takeover,  or  other

business combination or discourage a potential acquirer from making a tender offer or otherwise attempting to obtain control of us.

Risks Relating to Corporate Compliance

If we fail to comply with laws or regulations which regulate our business and which may change at any time, we may be fined or even lose our right to conduct some of our business.

A  variety  of  federal,  state,  local,  and  foreign  laws  and  regulations  apply  to  our  business,  including  those  discussed  in  "Item 1. Business." Failure  to  comply  with  applicable  requirements  may  lead  to  civil  or  criminal
penalties, require us to assume indemnification obligations or breach contractual provisions. We cannot guarantee that existing or future laws or regulations, including federal, state, local, or foreign tax laws, will not adversely
affect  our  business  (including  our  REIT  status),  increase  delays  or  result  in  additional  costs.  We  also  may  incur  additional  costs  as  a  result  of  liabilities  under  applicable  laws  and  regulations,  such  as  those  governing
environmental and safety matters. These factors may have a material adverse effect on us.

Risks Relating to Our REIT Status

Future dividend payments to our stockholders will reduce the availability of our cash on hand available to fund future discretionary investments, and may result in a need to incur indebtedness or issue equity securities to
fund growth opportunities.  In such event, the then current economic, credit market or equity market conditions will impact the availability or cost of such financing, which may hinder our ability to grow our per share
results of operations.

During  each  of  the  first  three  quarters  of  2021,  we  paid  a  common  stock  dividend  of  $1.33  per  share,  totaling  approximately  $1.7  billion.  In  October  2021,  our  board  of  directors  declared  a  quarterly  common  stock
dividend of $1.47 per share, which represents an increase of 11% from the quarterly common stock dividend declared during each of the first three quarters of 2021. We currently expect our common stock dividends over the
next 12 months to be a cumulative amount of at least $5.88 per share, or an aggregate amount of approximately $2.5 billion. Over time, we expect to increase our dividend per share generally commensurate with our realized
growth in cash flows. Any future dividends are subject to declaration by our board of directors. See notes 10 and 17 to our consolidated financial statements.

We operate as a REIT for U.S. federal income tax purposes. To remain qualified and be taxed as a REIT, we will generally be required to annually distribute at least 90% of our REIT taxable income (determined without
regard to the dividends paid deduction, excluding net capital gain and after the utilization of any available NOLs) to our stockholders. Our quarterly cash common stock dividend will delay the utilization of our NOLs and may
cause certain of the NOLs to expire without utilization. See also "Item 1. Business—REIT Status" and "Item 7. MD&A—General Overview—Common Stock Dividend."

As discussed in "Item 1. MD&A—Business—Strategy," we seek to invest our available capital, including the net cash generated by our operating activities and external financing sources, in a manner that we believe will
increase  long-term  stockholder  value  on  a  risk-adjusted  basis.  Our  historical  discretionary  investments  have  included  the  following  (in  no  particular  order):  construction  of  communications  infrastructure;  acquisitions  of
communications infrastructure; acquisitions of land interests (which primarily relate to land assets under towers); improvements and structural enhancements to our existing communications infrastructure; purchases of shares of
our common stock from time to time; and purchases, repayments or redemptions of our debt. External financing, including debt, equity, and equity-related issuances to fund future discretionary investments either (1) may not be
available to us or (2) may not be accessible by us at terms that would result in the investment of the net proceeds raised yielding incremental growth in our per share operating results. As a result, future dividend payments may
hinder our ability to grow our per share results of operations or otherwise adversely affect our ability to execute our business plan.

Remaining qualified to be taxed as a REIT involves highly technical and complex provisions of the Code. Failure to remain qualified as a REIT would result in our inability to deduct dividends to stockholders when
computing our taxable income, which would reduce our available cash.

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 net taxable income that is currently distributed to our common

stockholders.

While we intend to operate so that we remain qualified as a REIT, given the highly complex nature of the rules governing REITs, the importance of ongoing factual determinations, the possibility of future changes in our

circumstances, and the potential impact of future changes to laws and regulations impacting REITs, no assurance can be given that we will qualify as a REIT for any particular year.

22

In addition, the present U.S. federal tax treatment of REITs is subject to change, possibly with retroactive effect, by legislative, judicial or administrative action at any time, and any such change might adversely affect our

REIT status or benefits. We cannot predict the impact, if any, that such changes, if enacted, might have on our business. However, it is possible that such changes could adversely affect our business, including our REIT status.

If, in any taxable year, we fail to qualify for taxation as a REIT and are not entitled to relief under certain provisions of the Code, then:

•
•
•

we will not be allowed a deduction for dividends paid to stockholders in computing our taxable income;
we will be subject to federal and state income tax on our taxable income at regular corporate tax rates and, for years beginning before January 1, 2018, any applicable alternative minimum tax; and
we would be disqualified from re-electing REIT status for the four taxable years following the year during which we were so disqualified.

Although we may have federal NOLs available to reduce any taxable income, to the extent our federal NOLs have been utilized or are otherwise unavailable, any such corporate tax liability could be substantial, would
reduce  the  amount  of  cash  available  for  other  purposes  and  might  necessitate  the  borrowing  of  additional  funds  or  the  liquidation  of  some  investments  to  pay  any  additional  tax  liability.  Accordingly,  funds  available  for
investment would be reduced.

Under the Code, for taxable years beginning in or after 2018, no more than 20% of the value of the assets of a REIT may be represented by securities of one or more TRSs. These limitations may affect our ability to make
additional investments in non-REIT qualifying operations or assets, or in any operations held through TRSs. The net income of our TRSs is not required to be distributed to us, and income that is not distributed to us generally
will not be subject to the REIT income distribution requirement. However, there may be limitations on our ability to accumulate earnings in our TRSs and the accumulation or reinvestment of significant earnings in our TRSs
could result in adverse tax treatment. In particular, if the accumulation of cash in our TRSs causes the fair market value of our securities in our TRSs to exceed current or future limitations of the fair market value of our assets at
the end of any quarter, then we may fail to remain qualified as a REIT.

Complying with REIT requirements, including the 90% distribution requirement, may limit our flexibility or cause us to forgo otherwise attractive opportunities, including certain discretionary investments and potential
financing alternatives.

To remain qualified and be taxed as a REIT, we are required to satisfy the 90% distribution requirement as described above. We commenced declaring regular quarterly dividends to our common stockholders beginning
with the first quarter of 2014. See notes 10 and 17 to our consolidated financial statements. Any such dividends, however, are subject to the determination of and declaration by our board of directors based on then-current and
anticipated future conditions, including our earnings, net cash generated by operating activities, capital requirements, financial condition, our relative market capitalization, our existing federal NOLs of approximately $1.5
billion or other factors deemed relevant by our board of directors.

To the extent that we satisfy the 90% distribution requirement, but distribute less than 100% of our REIT taxable income (determined without regard to the dividends paid deduction, excluding net capital gain and after the
utilization of any available NOLs), we will be subject to federal corporate income tax on our undistributed taxable income. In addition, we will be subject to a 4% nondeductible excise tax if the actual amount that we pay out to
our stockholders for a calendar year is less than a minimum amount specified under the Code.

From  time  to  time,  we  may  generate  REIT  taxable  income  greater  than  our  cash  flow  as  a  result  of  differences  in  timing  between  the  recognition  of  taxable  income  and  the  actual  receipt  of  cash  or  the  effect  of
nondeductible capital expenditures, the creation of reserves or required debt or amortization payments. If we do not have other funds available in these situations, we could be required to borrow funds on unfavorable terms, sell
assets at disadvantageous prices, or distribute amounts that would otherwise be invested in future acquisitions to make distributions sufficient to enable us to pay out enough of our taxable income to satisfy the REIT dividend
requirement and to avoid corporate income tax and the 4% excise tax in a particular year. These alternatives could increase our costs or reduce our equity. Thus, compliance with the REIT requirements may hinder our ability to
grow, which could adversely affect the value of our common stock. Furthermore, the REIT dividend requirements may increase the financing we need to fund capital expenditures, future growth, or expansion initiatives, which
would increase our total leverage.

In addition to satisfying the 90% distribution requirement, to remain qualified as a REIT for tax purposes, we are required to continually satisfy tests concerning, among other things, the sources of our income, the nature
and diversification of our assets and the ownership of our capital stock. Compliance with these tests will require us to refrain from certain activities and may hinder our ability to make certain attractive investments, including the
purchase of non-qualifying assets, the expansion of non-real estate activities, or investments in the businesses to be conducted by our TRSs, and to that extent, limit our

23

opportunities and our flexibility to change our business strategy. Furthermore, acquisition opportunities in domestic or international markets may be adversely affected if we need or require the target company to comply with
some REIT requirements prior to completing any such acquisition. In addition, our status as a REIT may result in investor pressures not to pursue growth opportunities that are not immediately accretive.

Moreover, if we fail to comply with certain asset ownership tests, at the end of any calendar quarter, we must correct the failure within 30 days after the end of the calendar quarter or qualify for certain statutory relief
provisions to avoid losing our REIT qualification. As a result, we may be required to liquidate assets in adverse market conditions or forgo otherwise attractive investments. These actions may reduce our income and amounts
available for distribution to our stockholders.

REIT related ownership limitations and transfer restrictions may prevent or restrict certain transfers of our capital stock.

In order for us to continue to satisfy the requirements for REIT qualification, our capital stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months or during a
proportionate part of a shorter taxable year. Also, not more than 50% of the value of the outstanding shares of our capital stock may be owned, directly or indirectly, by five or fewer "individuals" (as defined in the Code to
include certain entities such as private foundations) during the last half of a taxable year. In order to facilitate compliance with the REIT rules, our Charter includes provisions regarding REIT-related ownership limitations and
transfer restrictions that generally prohibit any "person" (as defined in our Charter) from beneficially or constructively owning, or being deemed to beneficially or constructively own by virtue of the attribution provisions of the
Code, more than (1) 9.8%, by value or number of shares, whichever is more restrictive, of the outstanding shares of our common stock, or (2) 9.8% in aggregate value of the outstanding shares of all classes and series of our
capital stock. In addition, our Charter provides for certain other ownership limitations and transfer restrictions. Under applicable constructive ownership rules, any shares of capital stock owned by certain affiliated owners
generally would be added together for purposes of the ownership limitations. These ownership limitations and transfer restrictions could have the effect of delaying, deferring or preventing a transaction or a change in control of
our company that might involve a premium price for our capital stock or otherwise might be in the best interest of our stockholders.

Certifications

We submitted the Chief Executive Officer certification required by Section 303A.12(a) of the New York Stock Exchange ("NYSE") Listed Company Manual, relating to compliance with the NYSE's corporate governance
listing standards, to the NYSE on May 26, 2021 with no qualifications. We have included the certifications of our Chief Executive Officer and Chief Financial Officer required by Section 302 of the Sarbanes-Oxley Act of 2002
and related rules as Exhibits 31.1 and 31.2 to this 2021 Form 10-K.

Item 2.     Properties

Communications Infrastructure

We own, lease or manage more than 40,000 towers geographically dispersed throughout the U.S. Towers are vertical metal structures generally ranging in height from 50 to 300 feet. Our tenants' wireless equipment may

be placed on towers, building rooftops and other structures. Our towers are located on tracts of land that support the towers, equipment shelters and, where applicable, guy-wires to stabilize the tower.

Additionally, we own or lease more than 80,000 route miles of fiber primarily supporting our small cells and fiber solutions. The majority of our fiber assets are located in major metropolitan areas. Our small cells and

fiber are typically located outdoors and are often attached to public right-of-way infrastructure, including utility poles or street lights.

See the following for further information regarding our communications infrastructure:

•
•
•

"Item 1. Business—Overview" for information regarding our tower and fiber portfolios.
"Item 7. MD&A—Liquidity and Capital Resources—Material Cash Requirements" for information regarding our lease obligations.
"Schedule III - Schedule of Real Estate and Accumulated Depreciation" for further information on our productive properties.

Approximately 53% of our towers are leased or subleased or operated and managed under master leases, subleases, or other agreements with AT&T and T-Mobile, including agreements assumed by T-Mobile in connection
with its merger with Sprint. We have the option to purchase these towers at the end of their respective lease terms. We have no obligation to exercise such purchase options. See note 1 to our consolidated financial statements and
"Item 1A. Risk Factors" for a further discussion.

Substantially all of our communications infrastructure can accommodate additional tenancy, either as currently constructed or with appropriate modifications. Additionally, if so inclined as a result of a request for a tenant
addition, we could generally replace an existing tower with another tower, replace a small cell network antenna with another antenna or overlay additional fiber in order to provide additional coverage or capacity, subject to
certain restrictions.

Offices

Our  principal  corporate  headquarters  is  owned  and  located  in  Houston,  Texas.  In  addition,  we  have  offices  throughout  the  U.S.  in  locations  convenient  for  the  management  and  operation  of  our  communications

infrastructure, with significant consideration being given to the amount of our communications infrastructure located in a particular area. We believe that our facilities are suitable and adequate to meet our anticipated needs.

Item 3.     Legal Proceedings

We are periodically involved in legal proceedings that arise in the ordinary course of business. Most of these proceedings arising in the ordinary course of business involve disputes with landlords, vendors, collection
matters involving bankrupt tenants, zoning or siting matters, construction, condemnation, tax, employment, or wrongful termination matters. While the outcome of these matters cannot be predicted with certainty, management
does not expect any pending matters to have a material adverse effect on us.

Dividend Policy

PART II

We operate as a REIT for U.S. federal income tax purposes. To remain qualified and be 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 any available NOLs (determined without regard to the dividends paid deduction and excluding net capital gain). See also "Item 1. Business—REIT Status," "Item 1A. Risk Factors," "Item 7. MD&A—
General Overview—Common Stock Dividend," "Item 7. MD&A—Liquidity and Capital Resources—Financing Activities—Common Stock" and notes 9 and 10 to our consolidated financial statements.

Over time, we expect to increase our dividend per share generally commensurate with our growth in cash flows. The declaration amount and payment of any future dividends, however, are subject to the determination and
approval  of  our  board  of  directors  based  on  then-current  or  anticipated  future  conditions,  including  our  earnings,  net  cash  generated  by  operating  activities,  capital  requirements,  financial  condition,  our  relative  market
capitalization, our existing NOLs, or other factors deemed relevant by our board of directors. In addition, our ability to pay dividends is limited under certain circumstances by the terms of our debt instruments.

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

General Overview

Overview

We own, operate and lease shared communications infrastructure. See "Item 1. Business" for a further discussion of our business, including our long-term strategy, our REIT status, certain key terms of our tenant contracts
and growth trends in the demand for data. Site rental revenues represented 90% of our 2021 consolidated net revenues. The vast majority of our site rental revenues is of a recurring nature and has been contracted for in prior
years.

Highlights of Business Fundamentals and Results

• We operate as a REIT for U.S. federal income tax purposes (see "Item 1. Business—REIT Status" and notes 2 and 9 to our consolidated financial statements).
•

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), (7) the availability of additional spectrum and (8) increased government initiatives to support connectivity throughout the U.S.

◦ We expect U.S. wireless carriers will continue to focus on improving network quality and expanding capacity (including through 5G initiatives) 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.

•

Returning cash flows provided by operations to stockholders in the form of dividends (see also "Item 1. Business—Strategy")
◦ During 2021, we paid common stock dividends totaling approximately $2.4 billion. See "Item 7. MD&A—General Overview—Common Stock Dividend" for a discussion of the increase to our quarterly dividend

◦

in the fourth quarter of 2021.
Investing capital efficiently to grow long-term dividends per share
• Discretionary capital expenditures of $1.1 billion, 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
◦
◦
◦ As of December 31, 2021, weighted-average remaining term of approximately five years, exclusive of renewals exercisable at the tenants' option, currently representing approximately $31 billion of expected

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

future cash inflows.

Majority of our revenues from large wireless carriers

◦ Approximately three-fourths of our site rental revenues were derived from T-Mobile, AT&T and Verizon Wireless. See "Item 1A. Risk Factors" and note 14 to our consolidated financial statements for a further

discussion of our largest customers.

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

90% of our debt has fixed rate coupons.

Sustaining capital expenditures represented approximately 1% of net revenues.

Majority of our fiber assets are located in major metropolitan areas and are on public rights-of-way.
Minimal sustaining capital expenditure requirements
◦
Debt portfolio with long-dated maturities extended over multiple years, with the vast majority of such debt having a fixed rate. See note 7 to our consolidated financial statements and "Item 7A. Quantitative and
Qualitative Disclosures About Market Risk" for a further discussion of our debt.
◦
During 2021, we completed several debt transactions to refinance and extend the maturities of certain of our debt. See note 7 to our consolidated financial statements and "Item 7. MD&A—Liquidity and Capital
Resources—Financing Activities" for further discussion of our debt transactions.
◦ Our outstanding debt has a weighted average interest rate of 3.1% and weighted average maturity of approximately nine years (assuming anticipated repayment dates where applicable).
◦

Our debt service coverage and leverage ratios are comfortably within their respective financial maintenance covenants. See "Item 7. MD&A—Liquidity and Capital Resources—Debt Covenants" for a further
discussion of our debt covenants.
Significant cash flows from operations
◦ Net cash provided by operating activities was $2.8 billion.
◦

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.

Common Stock Dividend

In  the  aggregate,  we  paid  approximately  $2.4  billion  in  common  stock  dividends  in  2021.  During  each  of  the  first  three  quarters  of  2021,  we  paid  a  quarterly  common  stock  dividend  of  $1.33  per  share,  totaling
approximately $1.7 billion. In October 2021, our board of directors declared a quarterly common stock cash dividend of $1.47 per share, which represents an increase of approximately 11% from the quarterly common stock
dividend declared during each of the first three quarters of 2021. We currently expect our common stock dividends over the next 12 months to be a cumulative amount of at least $5.88 per share, or an aggregate amount of
approximately  $2.5  billion.  Over  time,  we  expect  to  increase  our  dividend  per  share  generally  commensurate  with  our  growth  in  cash  flows.  Any  future  common  stock  dividends  are  subject  to  declaration  by  our  board  of
directors. See notes 10 and 17 to our consolidated financial statements.

Outlook Highlights

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

◦ We expect that, when compared to full year 2021, our full year 2022 site rental revenue growth will be positively impacted by tenant additions, as large wireless carriers and fiber solutions tenants continue to focus

on meeting the increasing demand for data.

◦ We expect to continue to invest a significant amount of our available capital in the form of discretionary capital expenditures for 2022 based on the anticipated returns on such discretionary investments.

▪ We expect that our discretionary capital expenditures will increase as we accelerate the pace of small cell deployments.

◦ We also expect sustaining capital expenditures of approximately 2% of net revenues for full year 2022, consistent with historical annual levels.
◦

In January 2022, we entered into the T-Mobile Agreement, which we expect to result in approximately $250 million of additional straight-lined revenues for the year ended December 31, 2022. See "Item 1A. Risk
Factors" for a discussion of the future expected impact from the T-Mobile and Sprint network consolidation contemplated in the T-Mobile Agreement.

COVID-19

During the COVID-19 pandemic, and 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 the viability of communications networks, which are essential to public health and safety. In response to the pandemic, 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 included requiring work-from-home arrangements for a large portion of our
workforce, imposing travel restrictions for our employees where practicable, canceling physical participation in certain meetings, events and conferences, forming an internal committee to monitor and implement procedures for
the return of our workforce to an office setting, and other modifications to our business practices. We have re-opened our offices during the first quarter of 2022.

We will continue to actively monitor the situation and may take further actions as may be required by governmental authorities, as advised by public health officials or that we determine are in the best interests of our

employees, tenants, business partners and stockholders. See "Item 1A. Risk Factors" for further information.

We do not believe that COVID-19 had a material impact on our financial position, results of operations and cash flows for the year ended December 31, 2021. Given our access to various sources of liquidity and no near
term debt maturities other than Commercial Paper Notes and principal payments on amortizing debt, we currently anticipate that we will be able to maintain sufficient liquidity as we manage through the current environment.
See also "Item 1A. Risk Factors" and "Item 7. MD&A—Liquidity and Capital Resources—Liquidity Position."

Results of Operations

The following discussion of our results of operations for 2021 compared to 2020 should be read in conjunction with "Item 1. Business," "Item 7. MD&A—Liquidity and Capital Resources" and our consolidated financial
statements. For a discussion of our results of operations and financial condition for 2020 compared to 2019 that is not included in this 2021 Form 10-K, see "Part II, Item 7. Management's Discussion and Analysis of Financial
Condition and Results of Operations" in our Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC on February 22, 2021 .

The  following  discussion  of  our  results  of  operations  is  based  on  our  consolidated  financial  statements  prepared  in  accordance  with  GAAP,  which  require  us  to  make  estimates  and  judgments  that  affect  the  reported
amounts (see "Item 7. MD&A—Accounting and Reporting Matters—Critical Accounting Policies and Estimates" and note 2 to our consolidated financial statements). See "Item 7. MD&A—Accounting and Reporting Matters—
Non-GAAP and Segment Financial Measures" for a discussion of our use of (1) segment site rental gross margin, (2) segment services and other gross margin, (3) segment operating profit, including their respective definitions
and (4) Adjusted EBITDA, including its definition and a reconciliation to net income.

Our operating segments consist of (1) Towers and (2) Fiber. See note 14 to our consolidated financial statements for further discussion of our operating segments.

2021 and 2020

Total site rental revenues for 2021 grew by $399 million, or 8%, from 2020. This increase was predominately comprised of the factors depicted in the chart below:

(In millions of dollars)

Includes amortization of upfront payments received from long-term tenants and other deferred credits (commonly referred to as prepaid rent).

(a)
(b) Represents the contribution from recent acquisitions until the one-year anniversary of the acquisition.

Towers site rental revenues for 2021 were $3.8 billion and increased by $307 million, or 9%, from approximately $3.5 billion during 2020. 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 2021 were $1.9 billion and increased by $92 million, or 5%, from $1.8 billion from 2020. 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 from 2020 to 2021 was related to the previously-mentioned 9% increase in Towers site rental revenues and relatively fixed costs to operate our towers. The increase in Fiber

site rental gross margins was predominately related to the previously-mentioned 5% increase in Fiber site rental revenues.

Towers services and other gross margin for 2021 was $187 million and increased by $116 million, or 163%, from $71 million during 2020, which is a reflection of the increased volume of activity from carriers' network

enhancements and the volume and mix of services and other work.. Revenues from our services and other offerings are of a variable nature as these revenues are not under long-term contracts.

Towers operating profit for 2021 increased by $393 million, or 15%, from 2020. The increase in Towers operating profit was primarily related to the previously-mentioned increase in Towers site rental gross margin and

the previously-mentioned increase in Towers services and other gross margin.

Fiber operating profit for 2021 decreased by $276 million, or 20%, from 2020. The decrease in Fiber operating profit was primarily caused by the absence of $362 million of operating income recognized from the Sprint

Cancellation in 2020, partially offset by the previously-mentioned growth in our Fiber site rental revenues.

32

Depreciation, amortization and accretion was approximately $1.6 billion for 2021 and increased by $36 million, or 2%, from 2020. This increase predominately resulted from a corresponding increase in our gross property

and equipment due to capital expenditures.

Asset write-down charges for 2021 decreased by $53 million from 2020. Asset write-down charges in 2020 included the write-off of approximately $63 million in property and equipment which, following the Sprint

Cancellation, we deemed to have no alternative future use.

Interest expense and amortization of deferred financing costs were $657 million for 2021 and decreased by $32 million, or 5%, from $689 million during 2020. The decrease predominately resulted from a reduction in the
weighted-average interest rate on our debt as a result of our refinancing activities. See note 7 to our consolidated financial statements and "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" for a further
discussion of our debt.

As  a  result  of  repaying  certain  of  our  indebtedness  in  conjunction  with  our  refinancing  activities,  we  incurred  losses  on  retirement  of  long-term  obligations  of  $145  million  and  $95  million  for  the  years

ended 2021 and 2020, respectively. See note 7 to our consolidated financial statements.

The provisions for income taxes for 2021 and 2020 were $21 million and $20 million, respectively. For both 2021 and 2020, the effective tax rate differs from the federal statutory rate predominately due to our REIT
status, including the dividends paid deduction. See "Item 1. Business—REIT Status," "Item 7. MD&A—Accounting and Reporting Matters—Critical Accounting Policies and Estimates" and note 9 to our consolidated financial
statements.

Income from continuing operations was $1.2 billion during 2021 compared to $1.1 billion during 2020. The increase was related to (1) growth in our site rental activities in both our Towers and Fiber segments, (2) the
previously-mentioned increase in Towers services activity and (3) the previously-mentioned decrease in interest expense and amortization of deferred financing costs, partially offset by (i) the previously-mentioned losses on
retirement of long-term obligations and (ii) an increase in depreciation, amortization and accretion.

Loss from discontinued operations, net of tax, was $62 million during 2021 due to the ATO Settlement. See note 9 to our consolidated financial statements.

Net income attributable to CCIC stockholders increased by $40 million, or 4%, from 2020 to 2021. The increase was due to the previously-mentioned increase in income from continuing operations, partially offset by the

previously-mentioned loss from discontinued operations, net of tax.

Adjusted EBITDA increased $110 million, or 3%, from 2020 to 2021. The increase was predominately related to the growth in our site rental activities in both our Towers and Fiber segments as well as the previously-

mentioned increase in Towers service activity, partially offset by the absence of the other operating income recognized in 2020 related to the Sprint Cancellation.

Liquidity and Capital Resources

Overview

General. Our core business generates revenues under long-term tenant contracts (see "Item 1. Business—Overview" and "Item 7. MD&A—General Overview—Overview") from (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 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. See "Item 1. Business—Strategy" for a further discussion of our strategy.

We  have  engaged,  and  expect  to  continue  to  engage,  in  discretionary  investments  that  we  believe  will  maximize  long-term  stockholder  value.  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 2021 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,
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 from this target for various periods of
time. We have no significant contractual debt maturities until 2023 (other than Commercial Paper Notes that may be outstanding from time to time and 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 "Item 1. Business—REIT Status," "Item 7. MD&A—

General Overview" and note 9 to our consolidated financial statements.

Liquidity Position.  The  following  is  a  summary  of  our  capitalization  and  liquidity  position  as  of  December  31,  2021.  See "Item  7A.  Quantitative  and  Qualitative  Disclosures  About  Market  Risk"  and  note  7  to  our

consolidated financial statements for additional information regarding our debt as well as note 10 to our consolidated financial statements for additional information regarding our 2021 ATM 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  2021  ATM  Program.  Our  liquidity  uses  over  the  next  12  months  are  expected  to  include  (1)  debt  obligations  of  $337  million  (consisting  of  Commercial  Paper  Notes  and  principal  payments),  (2)
cumulative common stock dividend payments expected to be at least $5.88 per share, or an aggregate amount of approximately $2.5 billion (see "Item 7. MD&A—General Overview—Common Stock Dividend"), and
(3) capital expenditures. We may also purchase shares

34

of our common stock. 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.

Operating Activities. The decrease in net cash provided by operating activities of $266 million for 2021 from 2020 was due primarily to (1) payment received as a result of the Sprint Cancellation in 2020 and (2) a net
decrease from changes in working capital, offset by growth in our core business. 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 for 2021 decreased $409 million from 2020 primarily as a result of decreased discretionary capital expenditures in both our Towers and Fiber segments.

Our capital expenditures are categorized as discretionary, integration or sustaining 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 (including certain construction
projects that may take 18 to 36 months to complete). 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 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) Towers segment includes $65 million, $113 million and $208 million of capital expenditures incurred during the twelve months ended December 31, 2021, 2020 and 2019, respectively, in connection with tenant installations and upgrades on our towers.

Capital expenditures decreased from 2020 to 2021 and were primarily impacted by the completion of certain large fiber expansion projects during 2020 as well as the timing of Towers and Fiber tenant activity. See "Item 7.

MD&A—General Overview—Outlook Highlights" for a discussion of our expectations surrounding 2022 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 $5.88 per share over the next 12 months, or an aggregate amount of approximately $2.5 billion), (2) purchasing our common stock or (3) purchasing,
repaying,  or  redeeming  our  debt.  See "Item  7.  MD&A—General  Overview—Common  Stock  Dividend," "Item  7.  MD&A—Liquidity  and  Capital  Resources—Overview" and  notes  7,  10  and  17  to  our  consolidated  financial
statements.

In 2021, our financing activities predominately related to the following:

• paying an aggregate of $2.4 billion in dividends on our common stock;

•

•

•

issuing $3.25 billion aggregate principal amount of senior unsecured notes in February 2021, the net proceeds of which were used to (1) redeem all of the outstanding 5.250% Senior Notes, (2) repay a portion of the
outstanding Commercial Paper Notes and (3) repay a portion of outstanding borrowings under the 2016 Term Loan A;

issuing $750 million aggregate principal amount of senior unsecured notes in June 2021, the net proceeds of which were used to (1) to repay in full the previously outstanding Tower Revenue Notes, Series 2015-1,
Class C-2022, (2) to repay outstanding indebtedness under the CP Program and (3) for general corporate purposes.

entering into an amendment to the 2016 Credit Facility in June 2021 that provided for, among other things, (1) the extension of the maturity date of the Credit Facility from June 2024 to June 2026, (2) reductions to the
interest rate spread and unused commitment fee percentage upon meeting specified annual sustainability targets and increases to the interest rate spread and unused commitment fee percentage upon the failure to meet
specified annual sustainability thresholds and (3) the inclusion of "hardwired" LIBOR transition provisions consistent with those published by the Alternative Reference Rate Committee.

In 2020, our financing activities predominately related to the following:

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

• paying an aggregate of $85 million in dividends on our previously outstanding 6.875% Mandatory Convertible Preferred Stock;

•

•

issuing $1.25 billion aggregate principal amount of senior unsecured notes in April 2020, the net proceeds of which we used to repay outstanding indebtedness under the 2016 Revolver; and

issuing $2.5 billion aggregate principal amount of senior unsecured notes in June 2020, the proceeds of which, together with available cash, we used to redeem all of the previously outstanding 3.400% Senior Notes,
2.250% Senior Notes and 4.875% Senior Notes.

Position" for further discussion of our recent issuances, purchases, redemptions and repayments of debt.

Common Stock. See notes 10 and 17 to our consolidated financial statements for further information regarding our common stock as well as dividends declared and paid.

ATM Program. We previously maintained a 2018 ATM Program through which we had the right to issue and sell shares of our common stock having an aggregate gross sales price of up to $750 million to or through sales

agents. In March 2021, we terminated the formerly outstanding 2018 ATM Program with the entire gross sales price of $750 million remaining unsold.

In March 2021, we established the 2021 ATM Program through which we may issue and sell shares of our common stock having an aggregate gross sales price of up to $750 million. Sales under the 2021 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. We intend to use the net proceeds from any sales under the 2021 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. See also note 10 to our consolidated financial statements. As of February 18, 2022, we had approximately $750 million of gross sales of common stock availability remaining on our 2021 ATM
Program.

Mandatory Convertible Preferred Stock. In July and August 2020, all of our approximately 2 million shares of 6.875% Mandatory Convertible Preferred Stock then outstanding were converted into approximately 14
million shares of our common stock at a conversion rate (based on the applicable market value of our common stock and subject to certain anti-dilutive adjustments) of 8.8043 shares of common stock for each share of 6.875%
Mandatory Convertible Preferred Stock. See note 10 to our consolidated financial statements for further discussion of the July and August conversions into shares of our common stock.

Credit Facility. See note 7 to our consolidated financial statements for further information regarding our 2016 Credit Facility. As of February 18, 2022, there was approximately $5.0 billion in availability under the 2016
Revolver. The proceeds of our 2016 Revolver may be used for general corporate purposes, which may include the financing of capital expenditures, the repayment or repurchase of any outstanding indebtedness, acquisitions and
purchases of our common stock.

Commercial Paper Program. See note 7 to our consolidated financial statements for further information regarding our CP Program. As of February 18, 2022, the CP Program had $866 million outstanding. The proceeds
from our Commercial Paper Notes may be used for general corporate purposes, which may include the financing of capital expenditures, the repayment or repurchase of any outstanding indebtedness, acquisitions and purchases
of our common stock.

Restricted Cash. Pursuant to the indentures governing certain of our operating companies' debt securities, all rental cash receipts of the issuers of these debt instruments and their subsidiaries are restricted and held by an

indenture trustee. The restricted cash in excess of required reserve balances is subsequently released to us in accordance with the terms of the indentures. See also note 2 to our consolidated financial statements.

Material Cash Requirements

The following table summarizes our material cash requirements as of December 31, 2021. These material cash requirements relate primarily to our outstanding borrowings or lease obligations for land interests under our

towers. The debt maturities reflect contractual maturity dates and do not consider the impact of the principal payments that will commence following the anticipated repayment dates of certain debt (see footnote (b)).

(a) The impact of principal payments that will commence following the anticipated repayment dates of our Tower Revenue Notes is not considered. The Tower Revenue Notes have principal amounts of $250 million, $700 million and $750 million, with anticipated repayment dates

in 2023, 2025 and 2028, respectively. See note 7 to our consolidated financial statements for our definition of and additional information regarding the Tower Revenue Notes.

37

(b)

(c)

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 2043 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 (as defined in the indenture governing the applicable Tower Revenue Notes) of the issuers of the Tower Revenue Notes. The full year
2021 Excess Cash Flow (as defined in the indenture governing the applicable Tower Revenue Notes) of the issuers of the Tower Revenue Notes was approximately $933 million. We currently expect to refinance these notes on or prior to the respective anticipated repayment
dates.
Interest payments on the variable rate debt are based on estimated rates currently in effect. See "Item 1A. Risk Factors" for additional information about the anticipated discontinuation of LIBOR, which may impact the interest rates on our variable rate debt. Additionally, see note
7 to our consolidated financial statements for information regarding potential upward or downward adjustments to the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility if we achieve specified annual sustainability targets or fail to meet
annual sustainability thresholds. Each annual period presented assumes the downward adjustments in the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility.

(d) Amounts relate primarily to lease obligations for the land on which our towers are located and are based on the assumption that payments will be made for certain renewal periods exercisable at our option that are reasonably certain to be exercised and excludes our contingent
payments for operating leases (such as payments based on revenues derived from the communications infrastructure located on the leased asset) as such arrangements are excluded from our operating lease liability. See note 13 to our consolidated financial statements for further
discussion of our operating lease obligations. See also the table below summarizing remaining terms to expiration.

The following chart summarizes our rights to the land interests under our towers, including renewal terms exercisable at our option, as of December 31, 2021. As of December 31, 2021, the leases for land interests under

our towers had an average remaining life of approximately 36 years, weighted based on Towers site rental gross margin. See "Item 1A. Risk Factors" for a discussion of retaining land interests under our towers.

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 contain restrictive covenants that place restrictions on us and may limit our ability to, among other things, incur additional debt and
liens, purchase our securities, make capital expenditures, dispose of assets, undertake transactions with affiliates, make other investments, pay dividends or distribute excess cash flow. See note 7 to our consolidated financial
statements for further discussion of our debt covenants. See also "Item 1A. Risk Factors" for a discussion of compliance with our debt covenants. The following are ratios applicable to the financial maintenance covenants under

Accounting and Reporting Matters

Critical Accounting Policies and Estimates

Our critical accounting policies and estimates are those that we believe (1) are most important to the portrayal of our financial condition and results of operations or (2) require our most difficult, subjective or complex
judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. In many cases, the accounting treatment of a particular transaction is specifically prescribed by GAAP. In other
cases,  management  is  required  to  exercise  judgment  in  the  application  of  accounting  principles  with  respect  to  particular  transactions.  Accordingly,  actual  results  could  differ  materially  from  our  estimates.  The  critical
accounting policies and estimates for 2021 are not intended to be a comprehensive list of our accounting policies and estimates. See note 2 to our consolidated financial statements for a summary of our significant accounting
policies.

Lease Accounting — Lessee. For our Towers segment, our lessee arrangements primarily consist of ground leases for land under our towers. Ground leases for land are specific to each site and are generally for an initial
term of five to 10 years and are renewable (and cancelable after a notice period) at our option. We  also  enter  into  term  easements  and  ground  leases  in  which  we  prepay  the  entire  term.  For  our  Fiber  segment,  our  lessee
arrangements primarily include leases of fiber assets to facilitate our small cells and fiber solutions. The majority of our lease agreements have certain termination rights that provide for cancellation after a notice period and
multiple renewal options exercisable at our option. We include certain renewal option periods in the lease term when we determine that the options are reasonably certain to be exercised.

For both our Towers and Fiber segments, operating lease expense is recognized on a ratable basis, regardless of whether the payment terms require us to make payments annually, quarterly, monthly, or for the entire term in
advance. Certain of our ground lease and fiber lease agreements contain fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the change in
consumer price index ("CPI")). If the payment terms include fixed escalator provisions, the effect of such increases is recognized on a straight-line basis. We calculate the straight-line expense over the contract's estimated lease
term, including any renewal option periods that we deem reasonably certain to be exercised.

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

39

    
We review the carrying value of our ROU assets for impairment, similar to our other long-lived assets, whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. We could

record impairments in the future if there are changes in (1) long-term market conditions, (2) expected future operating results or (3) the utility of the assets that negatively impact the fair value of our ROU assets.

Revenue Recognition. 90% of our total revenue for 2021 consisted of site rental revenues, which are recognized on a ratable basis over the fixed, non-cancelable term of the relevant tenant contract, generally ranging from
five to 15 years for site rental revenues derived from wireless tenants and three to 20 years for site rental revenues derived from fiber solutions tenants, regardless of whether the payments from the tenant are received in equal
monthly amounts during the life of a tenant contract. Certain of our tenant contracts contain (1) fixed escalation clauses (such as fixed-dollar or fixed-percentage increases) or inflation-based escalation clauses (such as those tied
to  the  change  in  CPI),  (2)  multiple  renewal  periods  exercisable  at  the  tenant's  option  and  (3)  only  limited  termination  rights  at  the  applicable  tenant's  option  through  the  current  term.  If  the  payment  terms  call  for  fixed
escalations, upfront payments, or rent-free periods, the revenue is recognized on a straight-line basis over the fixed, non-cancelable term of the tenant contract. When calculating our straight-line rental revenues, we consider all
fixed elements of tenant contractual escalation provisions, even if such escalation provisions contain a variable element (such as an escalator tied to an inflation-based index) in addition to a minimum. To the extent we acquire
below-market tenant leases for contractual interests with tenants on the acquired communications infrastructure (for example with respect to small cells and fiber), we record the fair value as deferred credits and amortize such
deferred  credits  to  site  rental  revenues  over  their  estimated  lease  term.  Since  we  recognize  revenue  on  a  straight-line  basis,  a  portion  of  the  site  rental  revenues  in  a  given  period  represents  cash  collected  or  contractually
collectible in other periods. Our assets related to straight-line site rental revenues are included in "Other current assets" and "Deferred site rental receivables." Amounts billed or received prior to being earned are deferred and
reflected in "Deferred revenues" and "Other long-term liabilities." Amounts to which we have an unconditional right to payment, which are related to both satisfied or partially satisfied performance obligations, are recorded
within "Receivables, net" on the consolidated balance sheet.

As part of our effort to provide comprehensive communications infrastructure solutions, as an ancillary business, we also offer certain services primarily relating to our Towers segment, which represented 10% of our total
revenues  for  2021.  Services  and  other  revenue  consists  predominately  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"). Upon contract commencement, we assess
our services to tenants and identify performance obligations for each promise to provide a distinct service.

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

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

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

The vast majority of our services revenues relates to our Towers segment and generally have a duration of one year or less.

Accounting for Acquisitions — General. As described in "Item 1. Business," the  majority  of  our  communications  infrastructure  has  been  acquired  directly  or  indirectly  from  the  three  largest  wireless  carriers  (or  their
predecessors)  through  transactions  consummated  since  1999.  We  evaluate  each  of  our  acquisitions  to  determine  if  it  should  be  accounted  for  as  a  business  combination  or  as  an  acquisition  of  assets.  For  our  business
combinations, we allocate the purchase price to the assets acquired and liabilities assumed based on their estimated fair value at the date of acquisition. Any purchase price in excess of the net fair value of the assets acquired and
liabilities assumed is allocated to goodwill. See "Item 7. MD&A—Accounting and Reporting Matters—Accounting for Acquisitions—Valuation" below.

40

The determination of the final purchase price allocation could extend over several quarters resulting in the use of preliminary estimates that are subject to adjustment until finalized. Such changes could have a significant

impact on our consolidated financial statements.

Accounting for Acquisitions — Leases. With respect to business combinations that include towers that we lease and operate, such as the AT&T and T-Mobile leased and subleased towers (including towers owned by Sprint
prior  to  its  merger  with  T-Mobile),  we  evaluate  such  agreements  to  determine  treatment  as  finance  or  operating  leases.  The  evaluation  of  such  agreements  for  finance  or  operating  lease  treatment  previously  included
consideration of each of the lease classification criteria under ASC 840-10-25, namely (1) the transfer of ownership provisions, (2) the existence of bargain purchase options, (3) the length of the remaining lease term, and (4) the
present value of the minimum lease payments. With respect to the AT&T Acquisition, T-Mobile Acquisition, and the Sprint towers acquired in the Global Signal Acquisition, we determined that the tower leases were finance
leases and the underlying land leases were operating leases based upon the lease term criterion, after considering the fragmentation criteria applicable under ASC 840-10-25 to leases involving both land and buildings (i.e.,
towers). We determined that the fragmentation criteria was met, and the tower leases could be accounted for as finance leases apart from the land leases, which are accounted for as operating leases, since (1) the fair value of the
land in the aforementioned business combinations was greater than 25% of the total fair value of the leased property at inception and (2) the tower lease expirations occur beyond 75% of the estimated economic life of the tower
assets.

Accounting for Acquisitions — Valuation. As of December 31, 2021, our largest asset was property and equipment (which primarily consists of communications infrastructure) followed by goodwill, operating lease ROU

assets and intangible assets. Our identifiable intangible assets predominately relate to the site rental contracts and tenant relationships intangible assets.

The fair value of the vast majority of our assets and liabilities is determined by using either:

(1)
(2)

discounted cash flow valuation methods (for estimating identifiable intangibles such as site rental contracts and tenant relationships or operating lease right-of-use assets and lease liabilities acquired); or
estimates of replacement costs (for tangible fixed assets such as communications infrastructure).

The  purchase  price  allocation  requires  subjective  estimates  that,  if  incorrectly  estimated,  could  be  material  to  our  consolidated  financial  statements,  including  the  amount  of  depreciation,  amortization  and  accretion
expense. The most important estimates for measurement of tangible fixed assets are (1) the cost to replace the asset with a new asset and (2) the economic useful life after giving effect to age, quality, and condition. The most
important  estimates  for  measurement  of  intangible  assets  are  (1)  discount  rates  and  (2)  timing  and  amount  of  cash  flows  including  estimates  regarding  tenant  renewals  and  cancellations.  The  most  important  estimates  for
measurement of operating lease ROU assets and lease liabilities acquired are (1) present value of our future lease payments, including whether renewals or extensions should be measured, and (2) favorability or unfavorability to
the current market terms. With respect to business combinations that include towers that we lease and operate, such as the AT&T, T-Mobile and Sprint (prior to Sprint's merger with T-Mobile, completed on April 1, 2020) leased
and subleased towers, we evaluate such agreements to determine treatment as finance or operating leases and identification of any bargain purchase options.

We  record  the  fair  value  of  obligations  to  perform  certain  asset  retirement  activities,  including  requirements,  pursuant  to  our  ground  leases,  easements,  and  leased  facility  agreements  to  remove  communications
infrastructure or remediate the space upon which certain of our communications infrastructure resides. In determining the fair value of these asset retirement obligations we must make several subjective and highly judgmental
estimates such as those related to: (1) timing of cash flows, (2) future costs, (3) discount rates and (4) the probability of enforcement to remove the towers or small cells or remediate the land. We do not record an obligation for
asset retirement activities related to its fiber, as a settlement date is indeterminable and therefore a reasonable estimation of fair value cannot be made.

Accounting for Long-Lived Assets — Useful Lives. We are required to make subjective assessments as to the useful lives of our tangible and intangible assets for purposes of determining depreciation, amortization and
accretion expense that, if incorrectly estimated, could be material to our consolidated financial statements. Depreciation expense for our property and equipment is computed using the straight-line method over the estimated
useful lives of our various classes of tangible assets. The substantial portion of our property and equipment represents the cost of our communications infrastructure, which is generally depreciated with an estimated useful life
equal to the shorter of (1) 20 years or (2) the term of the lease (including optional renewals) for the land under our communications infrastructure.

The useful life of our intangible assets is estimated based on the period over which the intangible asset is expected to benefit us and gives consideration to the expected useful life of other assets to which the useful life may
relate. We review the expected useful lives of our intangible assets on an ongoing basis and adjust if necessary. Amortization expense for intangible assets is computed using the straight-line method over the estimated useful life
of each of the intangible assets. The useful life of the site rental contracts and tenant relationships intangible assets is limited by the maximum depreciable life of the

41

communications infrastructure (20 years), as a result of the interdependency of the communications infrastructure and site rental contracts and tenant relationships. In contrast, the site rental contracts and tenant relationships are
estimated to provide economic benefits for several decades because of the low rate of tenant cancellations and high rate of renewals experienced to date. Thus, while site rental contracts and tenant relationships are valued based
upon the fair value of the site rental contracts and tenant relationships which includes assumptions regarding both (1) tenants' exercise of optional renewals contained in the acquired leases and (2) renewals of the acquired leases
past  the  contractual  term  including  exercisable  options,  the  site  rental  contracts  are  amortized  over  a  period  not  to  exceed  20  years  as  a  result  of  the  useful  life  being  limited  by  the  depreciable  life  of  the  communications
infrastructure.

Accounting  for  Long-Lived  Assets  —  Impairment  Evaluation.  We  review  the  carrying  values  of  property  and  equipment,  intangible  assets,  or  other  long-lived  assets  for  impairment  whenever  events  or  changes  in

circumstances indicate that the carrying amounts may not be recoverable.

For purposes of our Towers segment, we utilize the following dual grouping policy for purposes of determining the unit of account for testing impairment of the site rental contracts and tenant relationships:

(1) we pool site rental contracts and tenant relationships intangible assets and property and equipment into portfolio groups; and
(2) we separately pool site rental contracts and tenant relationships by significant tenant or by tenant grouping for individually insignificant tenants, as appropriate.

We  first  pool  site  rental  contracts  and  tenant  relationships  intangible  assets  and  property  and  equipment  into  portfolio  groups  for  purposes  of  determining  the  unit  of  account  for  impairment  testing,  because  we  view
communications infrastructure as portfolios and communications infrastructure in a given portfolio and its related tenant contracts are not largely independent of the other communications infrastructure in the portfolio. We re-
evaluate the appropriateness of the pooled groups at least annually. This use of grouping is based in part on (1) our limitations regarding disposal of communications infrastructure, (2) the interdependencies of communications
infrastructure  portfolios,  and  (3)  the  manner  in  which  communications  infrastructure  is  traded  in  the  marketplace.  The  vast  majority  of  our  site  rental  contracts  and  tenant  relationships  intangible  assets  and  property  and
equipment  are  pooled  into  the  U.S.  owned  communications  infrastructure  group.  Secondly,  and  separately,  we  pool  site  rental  contracts  and  tenant  relationships  by  significant  tenant  or  by  tenant  grouping  for  individually
insignificant  tenants,  as  appropriate,  for  purposes  of  determining  the  unit  of  account  for  impairment  testing  because  we  associate  the  value  ascribed  to  site  rental  contracts  and  tenant  relationships  intangible  assets  to  the
underlying contracts and related tenant relationships acquired.

For purposes of our Fiber segment, we consider major U.S. markets where we have made significant investments to be the most appropriate level for purposes of grouping our long-lived assets for potential impairment

evaluation.

Our determination that an adverse event or change in circumstance has occurred that indicates that the carrying amounts may not be recoverable will generally involve (1) a deterioration in an asset's financial performance
compared to historical results, (2) a shortfall in an asset's financial performance compared to forecasted results, or (3) changes affecting the utility and estimated future demands for the asset. When considering the utility of our
assets, we consider events that would meaningfully impact (1) our communications infrastructure or (2) our tenant relationships. For example, consideration would be given to events that impact (1) the structural integrity and
longevity of our communications infrastructure or (2) our ability to derive benefit from our existing tenant relationships, including events such as tenant's bankruptcy or insolvency or loss of a significant tenant. During 2021,
there were no events or circumstances that caused us to review the carrying value of our intangible assets or property and equipment due in part to our assets performing consistently with or better than our expectations.

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

42

Approximately  3%  of  our  total  towers  currently  have  no  tenants.  We  continue  to  pay  operating  expenses  on  these  towers  in  anticipation  of  obtaining  tenants  on  these  towers  in  the  future,  primarily  because  of  the
demographics and continuing increase in demand for data in the areas around these individual towers. We estimate, based on current visibility, potential tenants on a majority of these towers. To the extent we do not believe there
are long-term prospects of obtaining tenants on an individual asset and all other possible avenues for recovering the carrying value have been exhausted, including sale of the asset, we appropriately reduce the carrying value of
such assets to fair value.

Accounting for Goodwill — Impairment Evaluation. We test goodwill for impairment on an annual basis, regardless of whether adverse events or changes in circumstances have occurred. The annual test begins with
goodwill and all intangible assets being allocated to applicable reporting units. We then perform a qualitative assessment to determine whether it is "more likely than not" that the fair value of the reporting unit is less than its
carrying amount. If we conclude that it is "more likely than not" that the fair value of a reporting unit is less than its carrying amount, we would be required to perform a quantitative goodwill impairment test. If the carrying
amount of a reporting unit is greater than its fair value, an impairment loss shall be recognized in an amount equal to such excess, limited to the total amount of goodwill allocated to the reporting unit. Our reporting units are the
same as our operating segments (Towers and Fiber). See note 14 to our consolidated financial statements. We performed our most recent annual goodwill impairment test as of October 1, 2021, which resulted in no impairments.

Deferred Income Taxes. We operate as a REIT for U.S. federal income tax purposes. Our REIT taxable income is generally not subject to federal and state income taxes as a result of the deduction for dividends paid and
any usage of our remaining NOLs.  Accordingly, the only provision or benefit for federal income taxes for the year ended December 31, 2021 relates to TRSs.  Furthermore, as a result of the deduction for dividends paid, some
or all of our NOLs related to our REIT may expire without utilization.  See "Item 1. Business—REIT Status" for a discussion of the impact of our REIT status. 

Our TRSs will continue to be subject, as applicable, to federal and state income taxes and foreign taxes in the jurisdictions in which such assets and operations are located.  Our ability to utilize our NOLs is dependent, in
part, upon us having sufficient future earnings to utilize our NOLs before they expire. If market conditions change materially and we determine that we will be unable to generate sufficient taxable income in the future to utilize
our NOLs, we would be required to record an additional valuation allowance, which would reduce our earnings. Such adjustments could cause a material effect on our results of operations for the period of the adjustment. The
change in our valuation allowance has no effect on our cash flows. For a further discussion of our benefit (provision) for income taxes, see "Item 7. MD&A—Results of Operations" and note 9 to our consolidated financial
statements.

Non-GAAP and Segment Financial Measures

In addition to the non-GAAP financial measures used herein and as discussed in note 14 to our 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, and segment other
operating (income) expense, less selling, general and administrative expenses attributable to the respective segment. All of these measurements of profit or loss are exclusive of depreciation, amortization and accretion, which
are shown separately. Additionally, certain costs are shared across segments and are reflected in our segment measures through allocations that management believes to be reasonable.

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), income (loss) from continuing

43

operations, 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 income (loss) from continuing operations 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 income (loss) from continuing
operations.

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

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

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

•

•

•

•

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;

44

•
•
•
•
•

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
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.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

Our primary exposures to market risks are related to changes in interest rates, which may adversely affect our results of operations and financial position. We seek to manage exposure to changes in interest rates where

economically prudent to do so by utilizing fixed rate debt. As of December 31, 2021 and December 31, 2020, we had no interest rate swaps.

Our interest rate risk as of December 31, 2021 relates primarily to the impact of interest rate movements on the following:

•
•
•

the potential refinancing of our $20.8 billion in existing debt, compared to $19.7 billion in the prior year;
our $2.2 billion of floating rate debt representing approximately 10% of total debt, compared to 9% in the prior year; and
potential future borrowings of incremental debt, including borrowings under our 2016 Credit Facility and issuances under the CP Program.

Potential Refinancing of Existing Debt

We have no significant contractual debt maturities (or anticipated repayment dates on our Tower Revenue Notes) over the next 12 months, other than Commercial Paper Notes that may be outstanding from time to time and

principal payments on certain outstanding debt. See below for a tabular presentation of our scheduled contractual debt maturities as of December 31, 2021 and a discussion of anticipated repayment dates.

Floating Rate Debt

We manage our exposure to market interest rates on our existing debt by controlling the mix of fixed and floating rate debt. As of December 31, 2021, we had $2.2 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. As of
December 31, 2020, we had approximately $1.9 billion of floating rate debt, none of which had LIBOR floors. See also "Item 1A. Risk Factors" for a discussion related to the anticipated discontinuation of LIBOR.

Potential Future Borrowings of Incremental Debt

We typically do not hedge our exposure to interest rates on potential future borrowings of incremental debt for a substantial period prior to issuance. See "Item 7. MD&A—Liquidity and Capital Resources" regarding our

liquidity strategy.

46

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 December 31, 2021. These debt
maturities reflect contractual maturity dates, and do not consider the impact of the principal payments that will commence following the anticipated repayment dates of certain debt (see footnotes (b) and (d)). See note 7 to our

(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 $250 million, $700 million and $750 million, with anticipated repayment dates in 2023, 2025 and 2028,

respectively.

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 2043 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 2021 Excess Cash Flow of the issuers of the Tower Revenue Notes was
approximately $933 million. We currently expect to refinance these notes on or prior to the respective anticipated repayment dates.

impact the interest rates on our variable rate debt. Additionally, see note 7 to our consolidated financial statements for information regarding potential upward or downward adjustments to the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility
if we achieve specified annual sustainability targets or fail to meet annual sustainability thresholds. Each annual period presented assumes the downward adjustments in the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility.

(f)    Predominately consists of outstanding indebtedness under our CP Program. Such amounts may be issued, repaid or re-issued from time to time.

Opinions on the Financial Statements and Internal Control over Financial Reporting

Report of Independent Registered Public Accounting Firm

We have audited the accompanying consolidated balance sheet of Crown Castle International Corp. and its subsidiaries (the “Company”) as of December 31, 2021 and 2020, and the related consolidated statements of operations
and comprehensive income (loss), of equity and of cash flows for each of the three years in the period ended December 31, 2021, including the related notes and financial statement schedules listed in the index appearing under
Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of December 31, 2021, based on criteria established in Internal
Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 2021 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all
material respects, effective internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The  Company's  management  is  responsible  for  these  consolidated  financial  statements,  for  maintaining  effective  internal  control  over  financial  reporting,  and  for  its  assessment  of  the  effectiveness  of  internal  control  over
financial reporting, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on
the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be
independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free
of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures
that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting
principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an
understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our
audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may
become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i)
relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not
alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the
accounts or disclosures to which it relates.

Revenue Recognition - Towers Segment

As described in Notes 2 and 14 to the consolidated financial statements, the Company recognized $3,804 million in site rental revenues and $601 million in services and other revenues from its Towers segment for the year
ended  December  31,  2021.  The  Company  generates  site  rental  revenues  from  its  core  business  by  providing  tenants  with  access  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, noncancelable term of the relevant tenant contract. The Company also offers certain services primarily relating to its Towers
segment, predominately consisting of (i) site development services and (ii) installation services. The transaction price for the Company's tower installation services consists of amounts for (i) permanent improvements to the
Company's towers that represent a lease component and (ii) 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.

The principal considerations for our determination that performing procedures relating to revenue recognition for the Towers segment is a critical audit matter are the significant auditor subjectivity and effort in performing
procedures and evaluating the audit evidence obtained related to tenant contracts and installation service agreements.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness
of  controls  relating  to  revenue  recognition  for  Towers.  These  procedures  also  included,  among  others  (i)  testing  the  completeness  and  accuracy  of  management’s  identification  of  the  contractual  terms  by  examining  tenant
contracts and installation service agreements on a test basis and (ii) testing the appropriateness of the timing and amount of revenue recognized based on contractual terms and estimated lease term for selected tenant contracts
and installation service agreements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Tabular dollars in millions, except per share amounts)

1.     Basis of Presentation

The consolidated financial statements include the accounts of Crown Castle International Corp. and its predecessor, as applicable (together, "CCIC"), and their subsidiaries, collectively referred to herein as the "Company."
All significant intercompany balances and transactions have been eliminated in consolidation. 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 14.

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 and T-Mobile, including agreements assumed by T-Mobile
following its merger with Sprint completed on April 1, 2020. 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.
Additional information concerning these towers is as follows:

◦

◦

22% of the Company's towers are leased or subleased or operated and managed under a master prepaid lease or other related agreements with AT&T for a weighted-average initial term of approximately 28 years,
weighted on Towers site rental gross margin. The Company has the option to purchase the leased and subleased towers from AT&T at the end of the respective lease or sublease terms for aggregate option payments
of approximately $4.2 billion, which payments, if such option is exercised, would be due between 2032 and 2048.

16% of the Company's towers are leased or subleased or operated and managed for an initial period of 32 years (through May 2037) under master leases, subleases, or other agreements with T-Mobile (which T-
Mobile assumed in connection with its merger with Sprint). The Company has the option to purchase in 2037 all (but not less than all) of such leased and subleased towers from T-Mobile for approximately $2.3
billion. 15% of the Company's towers are leased or subleased or operated and managed under a master prepaid lease or other related agreements with T-Mobile for a weighted-average initial term of approximately 28
years, weighted on Towers site rental gross margin. The Company has the option to purchase the leased and subleased towers from T-Mobile at the end of the respective lease or sublease terms for aggregate option
payments of approximately $2.0 billion, which payments, if such option is exercised, would be due between 2035 and 2049. In addition, through the acquisition of the rights to approximately 7,100 towers ("T-Mobile
Acquisition"), there are another 1% of the Company's towers subject to a lease and sublease or other related arrangements with AT&T. The Company has the option to purchase these towers that it does not otherwise
already own at the end of their respective lease terms for aggregate option payments of up to approximately $405 million, which payments, if such option is exercised, would be due prior to 2032 (less than $10
million would be due before 2025).

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 9.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Tabular dollars in millions, except per share amounts)

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.    Summary of Significant Accounting Policies

The following is a discussion of the Company's significant accounting policies in effect for the year ended December 31, 2021.

Restricted Cash

Restricted cash represents (1) the cash held in reserve by the indenture trustees pursuant to the indenture governing certain of the Company's debt instruments, (2) cash securing performance obligations such as letters of
credit, as well as (3) any other cash whose use is limited by contractual provisions. The restriction of rental cash receipts is a critical feature of certain of the Company's debt instruments, due to the applicable indenture trustee's
ability  to  utilize  the  restricted  cash  for  the  payment  of  (1)  debt  service  costs,  (2)  ground  rents,  (3)  real  estate  or  personal  property  taxes,  (4)  insurance  premiums  related  to  towers,  (5)  other  assessments  by  governmental
authorities and potential environmental remediation costs, or (6) a portion of advance rents from tenants. The restricted cash in excess of required reserve balances is subsequently released to the Company in accordance with the
terms of the indentures. See note 16 for a reconciliation of cash, cash equivalents and restricted cash.

Receivables Allowance

An  allowance  for  doubtful  accounts  is  recorded  as  an  offset  to  accounts  receivable.  The  Company  uses  judgment  in  estimating  this  allowance  and  considers  historical  collections,  current  credit  status,  or  contractual
provisions. Additions to the allowance for doubtful accounts are charged either to "Site rental costs of operations" or to "Services and other costs of operations," as appropriate, and deductions from the allowance are recorded
when specific accounts receivable are written off as uncollectible.

Lease Accounting

General. The Company evaluates whether a contract meets the definition of a lease whenever a contract grants a party the right to control the use of an identified asset for a period of time in exchange for consideration. To
the extent the identified asset is able to be shared among multiple parties, the Company has determined that one party does not have control of the identified asset and the contract is not considered a lease. The Company
accounts for contracts that do not meet the definition of a lease under other relevant accounting guidance (such as ASC 606 for revenue from contracts with customers).

Lessee. For its Tower segment, the Company's lessee arrangements primarily consist of ground leases for land under towers. Ground leases for land are specific to each site, generally contain an initial term of five to 10
years and are renewable (and cancelable after a notice period) at the Company's option. The Company also enters into term easements and ground leases in which it prepays the entire term. For its Fiber segment, the Company's
lessee arrangements primarily include leases of fiber assets to support the Company's small cells and fiber solutions.

The majority of the Company's lease agreements have certain termination rights that provide for cancellation after a notice period and multiple renewal options exercisable at the Company's option. The Company includes
renewal option periods in its calculation of the estimated lease term when it determines the options are reasonably certain to be exercised. When such renewal options are deemed to be reasonably certain, the estimated lease
term determined under ASC 842 will be greater than the non-cancelable term of the contractual arrangement. Although certain renewal periods are included in the estimated lease term, the Company would have the ability to
terminate or elect to not renew a particular lease if business conditions warrant such a decision.

The Company classifies its lessee arrangements at inception as either operating leases or finance leases. A lease is classified as a finance lease if at least one of the following criteria is met: (1) the lease transfers ownership
of the underlying asset to the lessee, (2) the lease grants the lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (3) the lease term is for a major part of the remaining economic life of
the underlying asset, (4) the present value of the sum of the lease payments equals or exceeds substantially all of the fair value of the underlying asset, or (5) the underlying asset is of such a specialized nature that it is expected
to have no alternative use to the lessor at the end of the lease term. A lease is classified as an operating lease if none of the five criteria described above for finance lease classification is met.

(Tabular dollars in millions, except per share amounts)

Right-of-use ("ROU") assets associated with operating leases are included in "Operating lease right-of-use assets" on the Company's consolidated balance sheet. Current and long-term portions of lease liabilities related to
operating leases are included in "Current portion of operating lease liabilities" and "Operating lease liabilities" on the Company's consolidated balance sheet, respectively. ROU assets represent the Company's right to use an
underlying asset for the estimated lease term and lease liabilities represent the Company's present value of its future lease payments. In assessing its leases and determining its lease liability at lease commencement or upon
modification, the Company is not able to readily determine the rate implicit for its lessee arrangements, and thus uses its incremental borrowing rate on a collateralized basis to determine the present value of the lease payments.
The  Company's  ROU  assets  are  measured  as  the  balance  of  the  lease  liability  plus  any  prepaid  or  accrued  lease  payments  and  any  unamortized  initial  direct  costs.  For  both  the  Towers  and  Fiber  segments,  operating  lease
expenses are recognized on a ratable basis, regardless of whether the payment terms require the Company to make payments annually, quarterly, monthly, or for the entire term in advance. Certain of the Company's ground lease
and fiber lease agreements contain fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the change in consumer price index ("CPI")). If the
payment terms include fixed escalator provisions, the effect of such increases is recognized on a straight-line basis. The Company calculates the straight-line expense over the tenant contract's estimated lease term, including any
renewal option periods that the Company deems reasonably certain to be exercised.

Lease agreements may also contain provisions for a contingent payment based on (1) the revenues derived from the communications infrastructure located on the leased asset, (2) the change in CPI or (3) the usage of the
leased asset. The Company's contingent payments are considered variable lease payments and are (1) not included in the initial measurement of the ROU asset or lease liability due to the uncertainty of the payment amount and
(2) recorded as expense in the period such contingencies are resolved.

ROU assets associated with finance leases are included in "Property and equipment, net" on the Company's consolidated balance sheet. Lease liabilities associated with finance leases are included in "Current maturities of
debt and other obligations" and "Debt and other long-term obligations" on the Company's consolidated balance sheet. For both its Towers and Fiber segments, the Company measures the lease liability for finance leases using
the effective interest method. The initial lease liability is increased to reflect interest on the liability and decreased to reflect payments made during the period. Interest on the lease liability is determined each period during the
lease term as the amount that results in a constant periodic discount rate on the remaining balance of the liability. The Company depreciates ROU assets for finance leases on a ratable basis over the applicable lease term.

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

Lessor. The Company's lessor arrangements primarily include tenant contracts for dedicated space (including dedicated fiber) on its shared communications infrastructure. The Company classifies its leases at inception as
operating, direct financing or sales-type leases. A lease is classified as a sales-type lease if at least one of the following criteria is met: (1) the lease transfers ownership of the underlying asset to the lessee, (2) the lease grants the
lessee an option to purchase the underlying asset that the lessee is reasonably certain to exercise, (3) the lease term is for a major part of the remaining economic life of the underlying asset, (4) the present value of the sum of the
lease payments equals or exceeds substantially all of the fair value of the underlying assets or (5) the underlying asset is of such a specialized nature that it is expected to have no alternative use to the lessor at the end of the lease
term. Furthermore, when none of the above criteria is met, a lease is classified as a direct financing lease if both of the following criteria are met: (1) the present value of the of the sum of the lease payments and any residual
value guaranteed by the lessee, that is not already reflected in the lease payments, equals or exceeds the fair value of the underlying asset and (2) it is probable that the lessor will collect the lease payments plus any amount
necessary to satisfy a residual value guarantee. A lease is classified as an operating lease if it does not qualify as a sales-type or direct financing lease. Currently, the Company classifies all of its lessor arrangements as operating
leases.

Site rental revenues from the Company’s lessor arrangements are recognized on a straight-line, ratable basis over the fixed, non-cancelable term of the relevant tenant contract, regardless of whether the payments from the
tenant are received in equal monthly amounts during the life of a tenant contract. Certain of the Company's tenant contracts contain fixed escalation clauses (such as fixed-dollar or fixed-percentage increases) or inflation-based
escalation clauses (such as those tied to the change in CPI). If the payment terms call for fixed escalations, upfront payments, or rent-free periods, the rental revenue is recognized on a straight-line basis over the fixed, non-
cancelable term of the agreement. When calculating straight-line site rental revenues, the Company considers all fixed elements of tenant contractual escalation provisions.

(Tabular dollars in millions, except per share amounts)

Certain of the Company's arrangements with tenants in its Fiber segment contain both lease and non-lease components. In such circumstances, the Company has determined (1) the timing and pattern of transfer for the
lease and non-lease component are the same and (2) the stand-alone lease component would be classified as an operating lease. As such, the Company has aggregated certain non-lease components with lease components and
has determined that the lease components (generally dedicated fiber) represent the predominant component of the arrangement.

Property and Equipment

Property and equipment is stated at cost, net of accumulated depreciation. Property and equipment includes land owned in fee and perpetual easements for land, which have no definite life. Depreciation  is  computed
utilizing the straight-line method at rates based upon the estimated useful lives of the various classes of assets. Depreciation of communications infrastructure is generally computed with a useful life equal to the shorter of 20
years or the term of the underlying ground lease (including optional renewal periods). Additions and permanent improvements to the Company's communications infrastructure are capitalized, while maintenance and repairs are
expensed.

Labor and interest costs incurred directly related to the construction of certain property and equipment are capitalized during the construction phase of projects. For the years ended December 31, 2021, 2020 and 2019, the
Company  had  $238  million,  $270  million  and  $246  million  in  capitalized  labor  costs,  respectively.  The  carrying  value  of  property  and  equipment  is  reviewed  for  impairment  whenever  events  or  changes  in  circumstances
indicate that the carrying amount of the assets may not be recoverable.

Abandonments and write-offs of property and equipment are recorded to "Asset write-down charges" on the Company's consolidated statement of operations and comprehensive income (loss) and were $19 million, $77
million and $17 million for the years ended December 31, 2021, 2020 and 2019, respectively. Asset write-down charges for the year ended December 31, 2020 included the write-off of property and equipment of approximately
$63 million which, following the Sprint Cancellation, was deemed to have no alternative future use. See note 15 for further information regarding the Sprint Cancellation.

Asset Retirement Obligations

Pursuant to its ground lease, easement and leased facility agreements, the Company records obligations to perform asset retirement activities, including requirements to remove communications infrastructure or remediate
the space on which certain of its communications infrastructure is located. The Company does not record an obligation for asset retirement activities related to its fiber, as a settlement date is indeterminable and therefore a
reasonable estimation of fair value cannot be made. Asset retirement obligations are included in "Other long-term liabilities" on the Company's consolidated balance sheet. The liability accretes as a result of the passage of time
and the related accretion expense is included in "Depreciation, amortization and accretion" on the Company's consolidated statement of operations and comprehensive income (loss). The associated asset retirement costs are
capitalized as an additional carrying amount of the related long-lived asset and depreciated over the useful life of such asset.

Goodwill

Goodwill represents the excess of the purchase price for an acquired business over the allocated value of the related net assets. The Company tests goodwill for impairment on an annual basis, regardless of whether adverse
events  or  changes  in  circumstances  have  occurred.  The  annual  test  begins  with  goodwill  and  all  intangible  assets  being  allocated  to  applicable  reporting  units.  The  Company's  reporting  units  are  the  same  as  its  operating
segments (Towers and Fiber). The Company then performs a qualitative assessment to determine whether it is "more likely than not" that the fair value of the reporting units is less than its carrying amount. If the Company
concludes it is "more likely than not" that the fair value of a reporting unit is less than its carrying amount, it is necessary to perform a quantitative goodwill impairment test. The quantitative goodwill impairment test compares
the estimated fair value of the reporting unit and the carrying value of the reporting unit. If the carrying amount of a reporting unit is greater than its fair value, an impairment loss shall be recognized in an amount equal to such
excess, limited to the total amount of goodwill allocated to the reporting unit. The Company performed its most recent annual goodwill impairment test as of October 1, 2021, which resulted in no impairments.

Intangible Assets

Intangible assets are included in "Site rental contracts and tenant relationships, net" and "Other intangible assets, net" on the Company's consolidated balance sheet and predominately consist of the estimated fair value of
site rental contracts and tenant relationships or other contractual rights, such as trademarks, that are recorded in conjunction with acquisitions. The site rental contracts and tenant relationships intangible assets are comprised of
(1) the current term of the existing leases, (2) the high rate of tenant retention, and (3) any associated relationships that are expected to generate value following the expiration of all renewal periods under existing leases.

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

The carrying value of other intangible assets with finite useful lives will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable.
The Company has a dual grouping policy for purposes of determining the unit of account for testing impairment of the site rental contracts and tenant relationships intangible assets. First, the Company pools the site rental
contracts and tenant relationships with the related communications infrastructure assets into portfolio groups for purposes of determining the unit of account for impairment testing. Second and separately, the Company evaluates
the site rental contracts and tenant relationships by significant tenant or by tenant grouping for individually insignificant tenants, as appropriate. If the sum of the estimated future cash flows (undiscounted) expected to result
from the use or eventual disposition of an asset is less than the carrying amount of the asset, an impairment loss is recognized. Measurement of an impairment loss is based on the fair value of the asset.

Deferred Credits

Deferred credits are included in "Deferred revenues" and "Other long-term liabilities" on the Company's consolidated balance sheet and consist of the estimated fair value of below-market tenant leases for contractual

interests with tenants on acquired communications infrastructure, which are amortized to site rental revenues.

Fair  value  for  these  deferred  credits  represents  the  difference  between  (1)  the  stated  contractual  payments  to  be  made  pursuant  to  the  in-place  lease  and  (2)  management's  estimate  of  fair  market  lease  rates  for  each
corresponding lease. Deferred credits are measured over a period equal to the estimated remaining economic lease term considering renewal provisions or economics associated with those renewal provisions, to the extent
applicable. Deferred credits are amortized over their respected estimated lease terms at the time of acquisition.

Deferred Financing Costs

Third-party costs incurred to obtain financing, with the exception of costs incurred related to revolving lines of credit, are deferred and are included as a direct deduction from the carrying amount of the related debt
liability in "Debt and other long-term obligations" on the Company's consolidated balance sheet. Third party costs incurred to obtain financing through a revolving line of credit are deferred and are included in "Other assets,
net" on the Company's consolidated balance sheet.

Revenue Recognition

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. 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-

61

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Tabular dollars in millions, except per share amounts)

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 $92 million and $152 million included in "Other current assets" and non-current amounts of $1.6
billion and $1.4 billion included in "Deferred site rental receivables" for the years ended December 31, 2021 and 2020, respectively. 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 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 consolidated balance sheet. The vast majority
of the Company’s services generally have a duration of one year or less.

Additional information on revenues. As of January 1, 2021 and December 31, 2021, a total of $2.8 billion and $2.6 billion of unrecognized revenue, respectively, was reported in "Deferred revenues" and "Other long-term
liabilities" on the Company's consolidated balance sheet. During the year ended December 31, 2021, approximately $595 million of the January 1, 2021 unrecognized revenue balance was recognized as revenue. As of January
1,  2020,  a  total  of  $2.9  billion  of  unrecognized  revenue  was  reported  in  "Deferred  revenues"  and  "Other  long-term  liabilities"  on  the  Company's  consolidated  balance  sheet.  During  the  year  ended  December  31,  2020,
approximately $575 million of the January 1, 2020 unrecognized revenue balance was recognized as revenue.

See note 3 for further discussion regarding the Company’s revenues.

Costs of Operations

Approximately half of the Company's site rental costs of operations expenses consist of Towers ground lease expenses, and the remainder includes fiber access expenses, property taxes, repairs and maintenance expenses,
employee compensation or related benefit costs, or utilities. Generally, the ground leases for land are specific to each site and are for an initial term of five years and are renewable for pre-determined periods. The Company also
enters  into  term  easements  and  ground  leases  in  which  it  prepays  the  entire  term  in  advance.  Fiber  access  expenses  primarily  consist  of  leases  of  fiber  assets  and  other  access  agreements  to  facilitate  the  Company's
communications infrastructure.

Ground lease and fiber access expenses are recognized on a ratable basis, regardless of whether the payment terms require the Company to make payments annually, quarterly, monthly, or for the entire term in advance.

Certain of the Company's ground lease and fiber access agreements contain fixed escalation clauses (such as fixed dollar or fixed percentage increases) or

62

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Tabular dollars in millions, except per share amounts)

inflation-based escalation clauses (such as those tied to the change in CPI). If the payment terms include fixed escalator provisions, the effect of such increases is recognized on a straight-line basis. The Company's liability
related  to  straight-line  expense  is  included  in  "Operating  lease  right-of-use  assets"  on  the  Company's  consolidated  balance  sheet.  The  Company's  assets  related  to  prepaid  agreements  is  included  in  "Prepaid  expenses"  and
"Operating lease right-of-use assets" on the Company's consolidated balance sheet.

Services and other costs of operations predominately consist of third-party service providers such as contractors and professional services firms and, to a lesser extent, internal labor costs.

The Company recognized $20 million as costs of operations during the year ended December 31, 2020 as a result of a reduction in staffing completed during the fourth quarter of 2020. Such costs were comprised of

employee severance payments and termination benefits and primarily impacted the Company's Fiber segment.

Acquisitions and Integration Costs

Direct or incremental costs related to a potential or completed business combination transaction are expensed as incurred. Such costs are predominately comprised of severance, retention bonuses payable to employees of
an acquired enterprise, temporary employees to assist with the integration of the acquired operations, fees paid for services (such as consulting, accounting, legal, or engineering reviews), and any other costs directly associated
with  the  transaction.  These  business  combination  costs  are  included  in  "Acquisition  and  integration  costs"  on  the  Company's  consolidated  statement  of  operations  and  comprehensive  income  (loss).  For  those  transactions
accounted for as asset acquisitions, these costs are capitalized as part of the purchase price.

Stock-based Compensation

Restricted Stock Units. The Company records stock-based compensation expense only for those unvested restricted stock units ("RSUs") for which the requisite service is expected to be rendered. The cumulative effect of
a change in the estimated number of RSUs for which the requisite service is expected to be or has been rendered is recognized in the period of the change in the estimate. To the extent that the requisite service is rendered,
compensation cost for accounting purposes is not reversed; rather, it is recognized regardless of whether or not the awards vest. A discussion of the Company's valuation techniques and related assumptions and estimates used to
measure the Company's stock-based compensation is as follows:

Valuation. The fair value of RSUs without market conditions is determined based on the number of shares relating to such RSUs and the quoted price of the Company's common stock at the date of grant. The Company
estimates the fair value of RSUs with market conditions granted using a Monte Carlo simulation. The Company's determination of the fair value of RSUs with market conditions on the date of grant is affected by its common
stock  price  as  well  as  assumptions  regarding  a  number  of  highly  complex  or  subjective  variables.  The  determination  of  fair  value  using  a  Monte  Carlo  simulation  requires  the  input  of  subjective  assumptions,  and  other
reasonable assumptions could provide differing results.

Amortization Method. The Company amortizes the fair value of all RSUs on a straight-line basis for each separately vesting tranche of the award (graded vesting schedule) over the requisite service periods.

Expected Volatility. The Company estimates the volatility of its common stock at the date of grant based on the historical volatility of its common stock.

Expected Dividend Rate. The expected dividend rate at the date of grant is based on the then-current dividend yield.

Risk-Free Rate. The Company bases the risk-free rate on the implied yield currently available on U.S. Treasury issues with an equivalent remaining term equal to the expected life of the award.

Forfeitures. The Company uses historical data and management's judgment about the future employee turnover rates to estimate the number of shares for which the requisite service period will not be rendered.

The Company amortizes deferred financing costs, discounts and premiums over the estimated term of the related borrowing using the effective interest yield method. Deferred financing costs and discounts are generally

presented as a direct reduction to the related debt obligation on the Company's consolidated balance sheet. 

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, including (1) taxes on any undistributed income and
(2) taxes related to the TRSs, In addition, the Company could under 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 ("Code"), to maintain qualification for taxation as a REIT.

Additionally, the Company has included in TRSs certain other assets and operations. Those 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 its REIT conversion and certain subsequent acquisitions into the REIT, the Company will be subject to a federal
corporate level tax rate (currently 21%) on any gain recognized from the sale of assets occurring within a specified period (generally 5 years) after the transfer date up to the amount of the built in gain that existed on the transfer
date, which is based upon the fair market value of those assets in excess of the Company's tax basis on the transfer date.  This gain can be offset by any remaining federal net operating loss carryforwards ("NOLs").

For the Company's TRSs, the Company accounts for income taxes using an asset and liability approach, which requires the recognition of deferred income tax assets and liabilities for the expected future tax consequences
of events that have been recognized in the Company's financial statements or tax returns. Deferred income tax assets and liabilities are determined based on the temporary differences between the financial statement and tax
bases of assets and liabilities using enacted tax rates. A valuation allowance is provided on deferred tax assets if it is determined that it is "more likely than not" that the asset will not be realized. The Company records a
valuation allowance against deferred tax assets when it is "more likely than not" that some portion or all of the deferred tax asset will not be realized. The Company reviews the recoverability of deferred tax assets each quarter
and based upon projections of future taxable income, reversing deferred tax liabilities or other known events that are expected to affect future taxable income, records a valuation allowance for assets that do not meet the "more
likely than not" realization threshold. Valuation allowances may be reversed if related deferred tax assets are deemed realizable based upon changes in facts and circumstances that impact the recoverability of the asset.

The Company recognizes a tax position if it is "more likely than not" that it will be sustained upon examination. The tax position is measured at the largest amount that is greater than 50 percent likely of being realized
upon ultimate settlement. The Company reports penalties and tax-related interest expense as a component of the benefit (provision) for income taxes. As of December 31, 2021 and 2020, the Company has not recorded any
material penalties related to its income tax positions. See note 9.

For the year ended December 31, 2019, 14 million common share equivalents related to the Company's previously outstanding 6.875% Convertible Preferred Stock were excluded from the dilutive common shares, because
the  impact  of  the  conversion  of  such  preferred  stock  would  be  anti-dilutive  based  on  the  Company's  common  stock  price  at  the  end  of  each  respective  year.  See  note  10  for  further  discussion  of  the  Company's  previously
outstanding 6.875% Convertible Preferred Stock.

Fair Values

The Company's assets and liabilities recorded at fair value are categorized based upon a fair value hierarchy that ranks the quality and reliability of the information used to determine fair value. The three levels of the fair
value hierarchy are (1) Level 1 — quoted prices (unadjusted) in active and accessible markets, (2) Level 2 — observable prices that are based on inputs not quoted in active markets but corroborated by market data, and (3)
Level 3 — unobservable inputs and are not corroborated by market data. The Company evaluates fair value hierarchy level classifications quarterly, and transfers between levels are effective at the end of the quarterly period.

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. There were no changes since December 31, 2020 in the Company's valuation techniques used to measure fair values. See note 8 for a further discussion of fair values.

(e) As of December 31, 2021, the undrawn availability under the 2016 Revolver was $4.3 billion.
(f) 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 0.080% to 0.300%, based on the Company's senior unsecured debt rating, per annum on the undrawn available amount under the 2016 Revolver.
See further discussion below regarding (1) potential adjustments to such percentages and (2) LIBOR transition provisions.

(g) The maturities of the Commercial Paper Notes, as defined below, when outstanding, may vary but may not exceed 397 days from the date of issuance.

The credit agreement governing the Company's 2016 Credit Facility contains financial maintenance covenants. The Company is currently in compliance with these financial maintenance covenants, and based upon current
expectations, the Company believes it will continue to comply with its financial maintenance covenants. In addition, certain of the Company's debt agreements also contain restrictive covenants that place restrictions on CCIC or
its subsidiaries and may limit the Company's ability to, among other things, incur additional debt and liens, purchase the Company's securities, make capital expenditures, dispose of assets, undertake transactions with affiliates,
make other investments, pay dividends or distribute excess cash flow.

Bank Debt

In January 2016, the Company established the 2016 Credit Facility, which was originally comprised of (1) a $2.5 billion 2016 Revolver maturing in January 2021, (2) a $2.0 billion 2016 Term Loan A maturing in January
2021 and (3) a $1.0 billion senior unsecured 364-day revolving credit facility ("364-Day Facility") maturing in January 2017.  The Company used the net proceeds from the 2016 Credit Facility (1) to repay the then outstanding
2012 Credit Facility and (2) for general corporate purposes. In February 2016, the Company used a portion of the net proceeds from the February 2016 Senior Notes (as defined below) offering to repay in full all outstanding
borrowings under the then outstanding 364-Day Facility.

In February 2017, the Company entered into an amendment to the 2016 Credit Facility to (1) incur additional term loans in an aggregate principal amount of $500 million and (2) extend the maturity of both the 2016 Term

Loan A and the 2016 Revolver to January 2022.

In August 2017, the Company entered into an amendment to the 2016 Credit Facility to (1) increase commitments on the 2016 Revolver by $1.0 billion, for total 2016 Revolver commitments of $3.5 billion, and (2) extend

the maturity of the Credit Facility to August 2022.

In June 2018, the Company entered into an amendment to the 2016 Credit Facility to (1) increase commitments on the 2016 Revolver by $750 million, for total 2016 Revolver commitments of $4.25 billion, and (2) extend

the maturity of the Credit Facility from August 2022 to June 2023.

In April 2019, the Company established a commercial paper program ("CP Program"), pursuant to which the Company may issue short-term, unsecured commercial paper notes ("Commercial Paper Notes"). Commercial
Paper Notes 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 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. For the year ended December 31, 2021, the Company had net issuances of $265 million under the CP Program. 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 as long-term based on its ability and intent to refinance the outstanding issuances on a long-term basis.

In June 2019, the Company entered into an amendment to the 2016 Credit Facility to (1) increase commitments on the 2016 Revolver by $750 million, for total 2016 Revolver commitments of $5.0 billion, and (2) extend

the maturity of the Credit Facility from June 2023 to June 2024.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Tabular dollars in millions, except per share amounts)

In  June  2021,  the  Company  entered  into  an  amendment  to  the  Credit  Agreement  that  provided  for,  among  other  things,  (1)  the  extension  of  the  maturity  date  of  the  Credit  Facility  from  June  2024  to  June  2026,  (2)
reductions to the interest rate spread ("Spread") and unused commitment fee ("Commitment Fee") percentage upon meeting specified annual sustainability targets ("Targets") and increases to the Spread and Commitment Fee
percentage upon the failure to meet specified annual sustainability thresholds ("Thresholds") and (3) the inclusion of "hardwired" LIBOR transition provisions consistent with those published by the Alternative Reference Rate
Committee. The Spread and Commitment Fee are subject to an upward adjustment of up to 0.05% and 0.01%, respectively, if the Company fails to achieve the Thresholds. The Spread and Commitment Fee are subject to a
downward adjustment of up to 0.05% and 0.01%, respectively, if the Company achieves the Targets. In January 2022, the Company submitted the required documentation and received confirmation from its administrative agent
that all Targets were met as of December 31, 2021, and, as such, the Spread and Commitment Fee percentage were reduced for 2022.

Securitized Debt

The Tower Revenue Notes and the Secured Notes, Series 2009-1, Class A-2 ("2009 Securitized Notes") (collectively, "Securitized Debt") are obligations of special purpose entities and their direct and indirect subsidiaries
(each an "issuer"), all of which are wholly-owned, indirect subsidiaries of CCIC. The Tower Revenue Notes and 2009 Securitized Notes are governed by separate indentures. The May 2015 Tower Revenue Notes and July 2018
Tower Revenue Notes (each as defined below) are governed by one indenture and consist of multiple series of notes, each with its own anticipated repayment date.

In May 2015, the Company issued $1.0 billion aggregate principal amount of Senior Secured Tower Revenue Notes ("May 2015 Tower Revenue Notes"), which were issued pursuant to the existing indenture and have
similar terms and security as the Company's then outstanding Tower Revenue Notes. The May 2015 Tower Revenue Notes originally consisted of (1) $300 million aggregate principal amount of 3.222% senior secured tower
revenue  notes  with  an  anticipated  repayment  date  of  May  2022  and  a  final  maturity  date  of  May  2042  and  (2)  $700  million  aggregate  principal  amount  of  3.663%  senior  secured  tower  revenue  notes  with  an  anticipated
repayment date of May 2025 and a final maturity date of May 2045. The Company primarily used the net proceeds of the May 2015 Tower Revenue Notes, together with proceeds received from the Company's sale of the
formerly 77.6% owned subsidiary that operated towers in Australia ("CCAL"), to (1) repay $250 million aggregate principal amount of the previously outstanding August 2010 Tower Revenue Notes, which had an anticipated
repayment date of August 2015, (2) repay all of the then outstanding WCP Secured Wireless Site Contracts Revenue Notes, Series 2010-1 ("WCP Securitized Notes"), (3) repay portions of outstanding borrowings under the
2012 Credit Facility and (4) pay related fees and expenses. In June 2021, the Company used a portion of the net proceeds from the June 2021 Senior Notes (as defined below) offering to repay $300 million of the May 2015
Tower Revenue Notes which had an anticipated repayment date of May 2022.

In July 2018, the Company issued $1.0 billion aggregate principal amount of Senior Secured Tower Revenue Notes ("July 2018 Tower Revenue Notes"), which were issued pursuant to the existing indenture and have
similar terms and security as the Company's existing Tower Revenue Notes. The July 2018 Tower Revenue Notes consist of (1) $250 million aggregate principal amount of 3.720% senior secured tower revenue notes with an
anticipated repayment date of July 2023 and a final maturity of July 2043 and (2) $750 million aggregate principal amount of 4.241% senior secured tower revenue notes with an anticipated repayment date of July 2028 and a
final maturity of July 2048. The Company used the net proceeds of the July 2018 Tower Revenue Notes, together with cash on hand, to repay all of the previously outstanding Tower Revenue Notes, Series 2010-6 and to pay
related fees and expenses. In addition to the July 2018 Tower Revenue Notes described above, in connection with Exchange Act risk retention requirements ("Risk Retention Rules"), an indirect subsidiary of the Company
issued and a majority-owned affiliate of the Company purchased approximately $53 million of the Senior Secured Tower Revenue Notes, Series 2018-1, Class R-2028 to retain an eligible horizontal residual interest (as defined
in the Risk Retention Rules) in an amount equal to at least 5% of the fair value of the July 2018 Tower Revenue Notes.

The Securitized Debt is paid solely from the cash flows generated by the operation of the towers held directly and indirectly by the issuers of the respective Securitized Debt. The Securitized Debt is secured by, among
other things, (1) a security interest in substantially all of the applicable issuers' assignable personal property, (2) a pledge of the equity interests in each applicable issuer and (3) a security interest in the applicable issuers' leases
with tenants to lease tower space (space licenses). The governing instruments of two indirect subsidiaries ("Crown Atlantic" and "Crown GT") of the issuers of the Tower Revenue Notes generally prevent them from issuing debt
and granting liens on their assets without the approval of a subsidiary of Verizon Communications. Consequently, while distributions paid by Crown Atlantic and Crown GT will service the Tower Revenue Notes, the Tower
Revenue Notes are not obligations of, nor are the Tower Revenue Notes secured by the cash flows or any other assets of, Crown Atlantic and Crown GT. As of December 31, 2021, the Securitized Debt was collateralized with
personal property and equipment with an aggregate net book value of approximately $855 million, exclusive of Crown Atlantic and Crown GT personal property and equipment.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Tabular dollars in millions, except per share amounts)

The  excess  cash  flows  from  the  issuers  of  the  Securitized  Debt,  after  the  payment  of  principal,  interest,  reserves,  expenses  and  management  fees,  are  distributed  to  the  Company  in  accordance  with  the  terms  of  the
indentures. If the Debt Service Coverage Ratio ("DSCR") (as defined in the applicable governing loan agreement) as of the end of any calendar quarter falls to a certain level, then all excess cash flow of the issuers of the
applicable debt instrument will be deposited into a reserve account instead of being released to the Company. The funds in the reserve account will not be released to the Company until the DSCR exceeds a certain level for two
consecutive calendar quarters. If the DSCR falls below a certain level as of the end of any calendar quarter, then all cash on deposit in the reserve account along with future excess cash flows of the issuers will be applied to
prepay the debt with applicable prepayment consideration.

The Company may repay the May 2015 Tower Revenue Notes or the 2009 Securitized Notes in whole or in part at any time after the second anniversary of the applicable issuance date and the July 2018 Tower Revenue
Notes from the date of issuance, provided in each case that such prepayment is accompanied by any applicable prepayment consideration. The Securitized Debt has covenants and restrictions customary for rated securitizations,
including provisions prohibiting the issuers from incurring additional indebtedness or further encumbering their assets.

Bonds—Senior Notes

In February 2021, the Company issued $3.25 billion aggregate principal amount of senior unsecured notes ("February 2021 Senior Notes"), which consisted of (1) $1.0 billion aggregate principal amount of 1.050%
senior unsecured notes due July 2026, (2) $1.0 billion aggregate principal amount of 2.100% senior unsecured notes due April 2031 and (3) $1.25 billion aggregate principal amount of 2.900% senior unsecured notes due April
2041. The Company used the net proceeds from the February 2021 Senior Notes offering to (1) redeem all of the outstanding 5.250% Senior Notes, (2) repay a portion of the outstanding Commercial Paper Notes and (3) repay a

At December 31, 2021, the Company had U.S. federal and state NOLs of approximately $1.5 billion and $0.6 billion, respectively, which are available to offset future taxable income. These amounts include approximately
$237 million of losses related to stock-based compensation. The Company also has foreign NOLs of $34 million. If not utilized, the Company's U.S. federal NOLs expire starting in 2025 and ending in 2036, the state NOLs
expire starting in 2022 and ending in 2036, and the foreign NOLs expire starting in 2023 and ending in 2036. The utilization of the NOLs is subject to certain limitations. The Company's U.S. federal and state income tax returns
generally remain open to examination by taxing authorities until three years after the applicable NOLs have been used or expired.

As of December 31, 2021, there were no unrecognized tax benefits that would impact the effective tax rate, if recognized.

From time to time, the Company is subject to examinations by various tax authorities in jurisdictions in which the Company has business operations. At this time, the Company is not subject to an Internal Revenue

Service examination.

On  April  26,  2021,  the  Company  entered  into  an  agreement  in  principle  with  the  Australian  Taxation  Office  ("ATO")  to  pay  A$83  million  to  settle  the  previously  disclosed  outstanding  audit  of  the  Australian  tax
consequences  of  the  Company’s  2015  sale  of  Crown  Castle  Australia  Holdings  Pty  Ltd  ("CCAL"),  formerly  a  77.6%  owned  Australian  subsidiary  of  the  Company  ("ATO  Settlement").  The  sale  of  CCAL  generated
approximately $1.2 billion in net proceeds to the Company, and resulted in a gain from the disposal of discontinued operations of $979 million for the year ended December 31, 2015.

On June 16, 2021, the Company entered into a definitive settlement agreement with the ATO evidencing the ATO Settlement. On July 1, 2021, the Company paid approximately $62 million (A$83 million), based on the
exchange rate in effect on that date, pursuant to the ATO Settlement. The Company recognized the ATO Settlement as a charge within discontinued operations in its consolidated statement of operations and comprehensive
income (loss) for the year ended December 31, 2021,

76

 
 
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
(Tabular dollars in millions, except per share amounts)

as this amount represented a reduction to the gain from the disposal of discontinued operations previously reported during the year ended December 31, 2015. The Company reflected the payment pursuant to the ATO Settlement
within discontinued operations in the Company's consolidated statement of cash flows for the year ended December 31, 2021.

The  Company  regularly  assesses  the  likelihood  of  additional  assessments  in  each  of  the  tax  jurisdictions  in  which  it  has  business  operations.  The  Company  has  no  uncertain  tax  positions  as  of  December  31,  2021.

Additionally, the Company does not believe any such additional assessments arising from other examinations or audits will have a material effect on the Company's financial statements.

As of December 31, 2021, the Company's deferred tax assets are included in "Other assets, net" and the Company's deferred tax liabilities are included in "Other long-term liabilities" on the Company's consolidated

balance sheet.

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 2021 ATM Program.

approximately 0.4 million RSUs were granted to the Company's executives and certain other employees and may vest on the third anniversary of the grant date based upon (a) the Company's total stockholder returns (defined as
share price appreciation plus the value of dividends paid during the performance period) and (b) the Company's total stockholder return compared to that of the companies in the Standard & Poor's 500 Index. Certain RSU
agreements contain provisions that result in forfeiture by the employee of any unvested shares in the event that the Company's common stock does not achieve certain performance targets. To the extent that the requisite service
is rendered, compensation cost for accounting purposes is not reversed; rather, it is recognized regardless of whether or not the market performance target is achieved.

The following table summarizes the assumptions used in the Monte Carlo simulation to determine the grant-date fair value for the RSUs with market conditions granted during the years ended December 31, 2021, 2020

and 2019.

The Company has received notices of claims and has been named as one of several defendants in lawsuits stemming from an April 2019 gas leak explosion in Durham, North Carolina, which occurred near an area where
the Company's subcontractors were installing fiber. The explosion resulted in two fatalities, physical injuries (some of which were serious), and property damage to surrounding buildings and businesses. Currently, the Company
is unable to determine the likelihood of an outcome or estimate a range of possible losses, if any, related to these lawsuits.

New York State Department of Transportation

In 2019, the State of New York passed legislation authorizing the Department of Transportation ("NYSDOT") to enter into agreements with any fiber provider for the use and occupancy of the state right-of-way for fiber
optic lines. The legislation authorizes the NYSDOT to charge a fee of up to fair market value for such use and occupancy. To date, the Company has paid fees relating to newly deployed fiber lines but has not been required to
pay, and has not recognized any costs in connection with, any fees relating to previously deployed fiber lines.

The Company believes that the legislation violates both federal and state law and is evaluating its legal options regarding any use and occupancy fees that may be assessed on previously deployed fiber. Currently, the

Company is unable to determine the likelihood of an outcome or reasonably estimate the amount of fees, if any, that it may be required to pay as a result of the legislation.

Other Matters

The Company is involved in various other claims, assessments, lawsuits or proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such other matters and it
is impossible to presently determine the ultimate costs or losses that may be incurred, if any, management believes the adverse resolution of such uncertainties and the incurrence of such costs should not have a material adverse
effect  on  the  Company's  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. See note 13 for a discussion of the operating lease commitments. 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.

Lessee Finance Leases

The vast majority of the Company's finance leases are related to the towers subject to prepaid master lease agreements with AT&T and T-Mobile, including agreements assumed by T-Mobile in connection with its merger
with Sprint, and are recorded as "Property and equipment, net" on the consolidated balance sheet. See note 1 for further discussion of the Company's prepaid master lease agreements. Finance leases and associated leasehold
improvements related to gross property and equipment and accumulated depreciation were $4.3 billion and $2.5 billion, respectively, as of December 31, 2021. Finance leases and associated leasehold improvements related to
gross property and equipment and accumulated depreciation were $4.4 billion and $2.3 billion, respectively, as of December 31, 2020. For the twelve months ended December 31, 2021

14. Operating Segments and Concentrations of Credit Risk

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 more than 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 more than 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 costs of operations, excluding stock-based compensation
expense and prepaid lease purchase price adjustments recorded in consolidated site rental costs of operations. The Company defines segment services and other gross margin as segment services and other revenues less segment
services and other costs of operations, excluding stock-based compensation expense recorded in consolidated services and other costs of operations. The Company defines segment operating profit as segment site rental gross
margin plus segment services and other gross margin, and segment other operating (income) expense, less selling, general and administrative expenses attributable to the respective segment. All of these measurements of profit
or loss are exclusive of depreciation, amortization and accretion, which are shown separately.

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, 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.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash and cash equivalents, restricted cash and trade receivables. The Company mitigates its risk with respect to cash
and cash equivalents by maintaining such deposits at high credit quality financial institutions and monitoring the credit ratings of those institutions. The Company's restricted cash is predominately held and directed by a trustee
(see note 2).

The Company derives the largest portion of its revenues from tenants in the wireless industry. The Company also has a concentration in its volume of business with T-Mobile, AT&T and Verizon Wireless or their agents
that accounts for a significant portion of the Company's revenues, receivables and deferred site rental receivables. The Company mitigates its concentrations of credit risk with respect to trade receivables by actively monitoring
the creditworthiness of its tenants, the use of tenant leases with contractually determinable payment terms or proactive management of past due balances.

15. Other Operating Income

During the fourth quarter of 2020, T-Mobile notified the Company that it was cancelling approximately 5,700 small cell nodes initially contracted with Sprint ("Sprint Cancellation") prior to its merger with T-Mobile. The
majority of the cancelled small cells were not yet constructed and, upon completion, would have been located at the same locations as other T-Mobile small cells. The Sprint Cancellation resulted in T-Mobile accelerating
payment of all contractual rental obligations associated with the approximately 5,700 small cells as well as the payment of capital costs incurred to date.

The Company received approximately $308 million from T-Mobile pursuant to the Sprint Cancellation, and recognized receipt of this payment as "Other operating income" on its consolidated statement of operations and

comprehensive income (loss) for the year ended December 31, 2020.

Additionally, the Company previously received upfront payments from Sprint for certain of the small cells subject to the Sprint Cancellation, which the Company previously recorded as "Deferred revenues" and "Other
long-term liabilities" on its consolidated balance sheet. As a result of the Sprint Cancellation, during the fourth quarter of 2020, the Company recognized the unamortized portion of such upfront payments, or approximately
$54 million, as "Other operating income" on its consolidated statement of operations and comprehensive income (loss) for the year ended December 31, 2020.

See also note 2 for a discussion of the Company's separate evaluation and write-off during the year ended December 31, 2020 of property and equipment previously recorded related to the cancelled small cells.

3.849% Secured Notes Redemption

On February 18, 2022, the applicable trustee, on behalf of the Company, issued a notice of redemption to holders of the 3.849% Secured Notes that the Company will redeem all of the $1.0 billion outstanding aggregate
principal amount of such notes on March 21, 2022. The redemption price for the 3.849% Secured Notes will be calculated in accordance with the indenture governing the 3.849% Secured Notes, plus accrued and unpaid interest
on the 3.849% Secured Notes. The Company expects the redemption of the 3.849% Secured Notes to result in a loss on retirement of long-term obligations of approximately $29 million that will be reflected in the first quarter
2022 condensed consolidated statement of operations, predominately as a result of make-whole premiums.

Item 9A.    Controls and Procedures

(a) Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

In connection with the preparation of the 2021 Form 10-K, the Company's management conducted an evaluation, under the supervision and with the participation of the Company's Chief Executive Officer ("CEO") and
Chief Financial Officer ("CFO"), of the effectiveness of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended ("Exchange
Act")). Based upon their evaluation, the CEO and CFO concluded that as of December 31, 2021, the Company's disclosure controls and procedures were effective to provide reasonable assurance that information required to be
disclosed  by  the  Company  in  the  reports  filed  or  submitted  by  it  under  the  Exchange  Act  is  recorded,  processed,  summarized,  and  reported  within  the  time  periods  specified  in  the  SEC's  rules  and  forms,  and  to  provide
reasonable assurance that information required to be disclosed by the Company in such reports is accumulated and communicated to the Company's management, including its CEO and CFO, as appropriate to allow timely
decisions regarding required disclosure.

(b) Management's Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) for the Company. Under the supervision
and with the participation of the Company's CEO and CFO, management assessed the effectiveness of the Company's internal control over financial reporting based on the framework described in Internal Control – Integrated
Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company's internal control over financial reporting is a process designed to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States of America. The Company's internal control
over financial reporting includes those policies and procedures that:

•
•

•

pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles in the United States of America, and
that receipts and expenditures of the Company are being made only in accordance with authorization of management and directors of the Company; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisitions, use or disposition of the Company's assets that could have a material effect on the financial statements.

Management  has  assessed  the  effectiveness  of  the  Company's  internal  control  over  financial  reporting  as  of  December  31,  2021.  Based  on  the  Company's  assessment,  management  has  concluded  that  the  Company's
internal control over financial reporting was effective as of December 31, 2021 to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting
purposes in accordance with generally accepted accounting principles in the United States of America.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2021 has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in their

report which appears in Part II, Item 8 of the 2021 Form 10-K.

(c) Changes in Internal Control Over Financial Reporting

There have not been any changes in the Company's internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the most recent fiscal quarter that have

materially affected or are reasonably likely to materially affect the Company's internal control over financial reporting.

(d) Limitations on the Effectiveness of Controls

Because of its inherent limitations, the Company's internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the

risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Amended and Restated
Crown Castle International Corp. Extended Service Separation Program

Crown Castle International Corp. (“Company”) previously adopted the Crown Castle International Corp. Extended Service Separation Program (“Program”) to provide certain compensation
benefits to long-term employees of the Company and affiliates of the Company (collectively, “Company Group”) who voluntarily terminate their employment with the Company Group. The
Company has, effective February 17, 2022 (“Effective Date”), amended and restated the Program to make certain changes to its terms. An employee is eligible to participate in the Program
if  he  or  she  has  (i)  attained  certain  minimum  age  and  employment  criteria,  (ii)  provided  timely  notice  to  the  Company,  (iii)  agreed  to  timely  execute  a  Separation  Agreement  (defined
below), including a general release of claims against the Company Group as well as a confidentiality agreement and an assignment of inventions, (iv) for individuals who have received
awards of restricted stock units (“RSUs”) under the Company’s 2013 Long-Term Incentive Plan (“LTIP”), agreed to timely execute an agreement containing post-employment restrictions,
including non-competition and non-solicitation covenants, and (v) continued to work for the Company Group in “good standing” until his or her employment termination date as selected
and approved by the Company hereunder (“Designated Termination Date”; the terms of “Miscellaneous–Not a Contract of Employment” below shall apply at all times with respect to any
Designated Termination Date).

An employee of the Company Group who is in “good standing”  is eligible to participate in the Program if he or she satisfies the following requirements. An employee who is in “good
standing” and satisfies each of the applicable requirements listed below and terminates on a Designated Termination Date will be treated as a “Qualifying Participant” for purposes of the
Program.

with timely notice of his or her intent to terminate employment with the Company. The Company shall, from time to time, establish a minimum notification period (“Minimum Notification
Period”) and maximum extension period (“Maximum Extension Period”) which shall apply for purposes of this Program (see “Administration of the Program” below). The  notification
provided by the employee must propose the employee’s preferred termination date (“Requested Termination Date”), which should be a date after such Minimum Notification Period. This
notification must be provided using the electronic mail address Retirement@crowncastle.com.

4.

Approval Requirement. The VPTR must formally approve in writing the employee’s eligibility for participation in the Program as well as the Designated Termination Date
before an employee is eligible to receive any benefits under this Program. The VPTR shall, in his or her sole discretion, select and approve a Designated Termination Date for the employee,
which Designated Termination Date may be earlier or later than the Requested Termination Date; provided, however, that (i) the Company shall not be required to provide any additional
compensation to the employee if the VPTR selects a Designated Termination Date earlier than the Requested Termination Date and (ii) the Designated Termination Date selected by the
VTPR shall be no later than the Maximum Extension Period after the Requested Termination Date.

5.

Continued Employment Requirement. In order to be eligible to receive benefits under the Program, an eligible employee must continue to work as an employee for a member
of the Company Group in “good standing”, as determined by the VPTR, between the date that a proposed termination notice is delivered to the Company (as described in paragraph 3 above)
and the employee’s Designated Termination Date. If an otherwise eligible employee does not satisfy this requirement, he or she will not receive any separation benefits under this Program.

6.

Separation Agreement Requirement. In order to be eligible to participate in this Program, an otherwise qualifying employee will be required to fully release any and all claims
that he or she may have against the members of the Company Group and their employees, agents, directors, officers and representatives, and make certain other promises, including with
respect to confidentiality of information and assignment of inventions, by timely executing a copy of the Separation Agreement relating to the Program (“Separation Agreement”) with one
or more members of the Company Group, as designated by the Company. A copy of the Separation Agreement is available upon request by contacting Retirement@crowncastle.com. An
employee  who  has  elected  to  participate  in  the  Program  will  receive  his  or  her  Separation  Agreement  at  least  60  days  before  the  employee’s  Designated  Termination  Date  and  will  be
required to execute the Separation Agreement on his or her Designated Termination Date. An employee will have seven days to revoke the Separation Agreement after signing; however, if
an employee elects to revoke the Separation Agreement, then the employee will not receive any separation benefits under this Program.

7.

Non-competition Non-solicitation and Cooperation Agreement Requirement. If an eligible employee has received an Eligible RSU Award (defined below), he or she will be
required to timely execute an agreement with one or more members of the Company Group, as designated by the Company, including terms regarding post-employment obligations and
conditions, including cooperation, non-competition, and non-solicitation, the terms of which may be incorporated into the Separation Agreement referenced above. A copy of this agreement
is available upon request by contacting Retirement@crowncastle.com.

Program Benefits

An employee who is classified as a Qualifying Participant on his or her Designated Termination Date will be eligible to receive the following benefits upon termination of employment with
the Company Group:

1.

Conditional Special Vesting. If  a  Qualifying  Participant  holds  any  Eligible  RSU  Awards  on  his  or  her  Designated  Termination  Date,  then  the  Qualifying  Participant  may
receive  Conditional  Special  Vesting  (defined  below)  pursuant  to  this  Section.  From  and  after  the  termination  of  a  Qualifying  Participant’s  employment,  and  so  long  as  the  Qualifying
Participant is, and has continuously been from and after such termination, in strict compliance with each of the requirements described in paragraphs 6 and 7 of the “Eligibility Criteria”
section above (which compliance shall be determined at all times by the VPTR, in his or her sole discretion), then all Eligible RSU Awards held by the Qualifying Participant shall continue
to have the opportunity to have their transfer and forfeiture restrictions lapse (i.e., “vest”) pursuant to the terms (other than any employment requirement) of the applicable Eligible RSU
Award agreements as if the Qualifying Person had remained an employee of the Company Group from and after the termination date (“Conditional Special Vesting”).

a.    Each Eligible RSU Award shall be forfeited on the earlier of (i) the date upon which the Qualifying Participant elects to revoke the Separation Agreement (or any other
agreement containing the requirements of paragraphs 6 and 7 of “Eligibility Criteria” above), and (ii) the date upon which the Qualifying Participant violates any provision of the Separation
Agreement (or any other agreement containing the requirements of paragraphs 6 and 7 of “Eligibility Criteria” above), as determined by the Company in its sole discretion.

b.    Except as otherwise expressly set forth herein, each of the Qualifying Participant’s Eligible RSU Awards will remain subject to the terms of its Eligible RSU Award

agreement and the LTIP.

c.    For purposes of this Program, the term “Eligible RSU Award” means, except as specified in the following sentence, a time-based or performance-based RSU that is
granted to an eligible employee at least six months prior to the date of the Employee’s termination of employment. RSUs granted outside of the annual long term incentive compensation
award cycle, such as new hire RSUs, promotion RSUs and retention RSUs, will not be treated as Eligible RSU Awards.

2.

Retirement Benefit. A Qualifying Participant who does not hold any Eligible RSU Awards on his or her termination date will receive a retirement contribution to his or her
account under the Crown Castle International Corp. 401(k) Plan or the Crown Castle Puerto Rico 1165(e) Plan, as applicable (“Qualified Plan”). The amount of the retirement contribution
will be equal to the lesser of:

a.

Twenty-five percent (25%) of the Qualifying Participant’s Final Base Compensation (defined below); or

b.

The maximum annual contribution which may be made by the Company to the Qualified Plan under applicable law, including Section 415(c) of the Internal Revenue
Code of 1986, as amended, without necessitating additional unintended contributions in order to satisfy applicable coverage or discrimination tests, for the year in which the Qualifying
Participant terminates his or her employment with the Company.

The retirement contribution will be funded to the Qualified Plan in the form of a fully nonforfeitable, discretionary nonelective employer contribution, which shall be made to the

3

Qualifying  Participant’s  account  at  a  time  determined  by  the  Company  in  its  sole  discretion  but  not  later  than  the  funding  date  which  applies  to  discretionary  nonelective  employer
contributions made by the Company for the plan year during which the Qualifying Participant has terminated his or her employment.

For purposes of this Program, the term “Final Base Compensation” means either (i) a Qualifying Participant’s annualized base salary as in effect on the date that the Qualifying Participant
terminates his or her employment with the Company Group, or (ii) a Qualifying Participant’s annualized base hourly pay, calculated using the Qualifying Participant’s base hourly rate of
pay as in effect on the date that the Qualifying Participant terminates his or her employment with the Company group and the average number of weekly hours worked by the Qualifying
Participant for the three-year period preceding the date that the Qualifying Participant terminates his or her employment with the Company Group.

Administration of the Program

General. This Program shall be administered by the VPTR. The VPTR shall supervise the administration and enforcement of the Program according to the terms and provisions outlined
above and the rules approved by the Compensation Committee of the Company’s Board of Directors. The VPTR shall have all powers necessary to accomplish these purposes, including,
but not by way of limitation, the right, power, and authority:

•

•

•

•

•

•

•

to establish, from time to time, the applicable Minimum Notification Period and Maximum Extension Period;

to select and approve the Designated Termination Date for each Qualifying Participant who elects to participate in the Program;

to make rules, regulations, and bylaws for the administration of the Program that are not inconsistent with the terms and provisions hereof, and to interpret and enforce the terms of
the Program and the rules and regulations promulgated thereunder;

to construe in his or her discretion all terms, provisions, conditions, and limitations of the Program;

to correct any defect or to supply any omission or to reconcile any inconsistency that may appear in the Program in such manner and to such extent as he or she shall deem in his or
her discretion expedient to effectuate the purposes of the Program;

to determine in his or her discretion all questions relating to eligibility, including whether and when an employee has incurred a termination of employment and the reason for such
termination; and

to make a determination in his or her sole discretion as to the right of any individual to a benefit under the Program and to prescribe procedures to be followed by employees in
obtaining benefits hereunder.

Claims Review Procedure. If an employee submits a notice to the Company asking to participate in the Program and his or her participation in the Program is not approved in writing by the
VPTR, he or she may submit a written claim for reconsideration of benefits under the Program to the VPTR outlining the basis for such claim. The VPTR will make a final decision as to a
claim within 90 days after receipt of the claim. If a decision is not given to the employee within such claim review period, the claim shall be treated as if it were denied on the last day of the
claims review period.

Miscellaneous

Not a Contract of Employment. The adoption and maintenance of the Program shall not be deemed to be a contract between the Company Group and any individual or to be consideration
for the employment of any individual. Nothing herein shall be deemed to (i) give any individual the right to be retained in the employ of the Company Group, (ii) restrict the right of the
Company Group to discharge any individual at any time, (iii) give the Company Group the right to require any individual to remain in the employ of the Company Group, or (iv) restrict any
individual’s right to terminate his or her employment at any time.

Alienation  of  Interest  Forbidden.  The  interest  of  an  eligible  employee  under  the  Program  may  not  be  sold,  transferred,  assigned,  or  encumbered  in  any  manner,  either  voluntarily  or
involuntarily, and any attempt so to anticipate, alienate, sell, transfer, assign, pledge, encumber, or charge the same shall be null and void; neither shall the benefits hereunder be liable for or
subject  to  the  debts,  contracts,  liabilities,  engagements  or  torts  of  any  individual  to  whom  such  benefits  or  funds  are  payable,  nor  shall  they  be  an  asset  in  bankruptcy  or  subject  to
garnishment, attachment or other legal or equitable proceedings.

Amendment and Termination. The Compensation Committee of the Company’s Board of Directors may from time to time, in its sole discretion, amend or discontinue, in whole or in part,
any or all of the provisions of the Program on behalf of the Company Group. The Compensation Committee may interpret, modify or terminate the Program in its sole discretion at any time;
provided, that, without the consent of the Qualifying Participant, no change in the Program may be made that would adversely affect the rights of a Qualifying Participant with respect to
benefits agreed to pursuant to the terms and conditions of a Separation Agreement previously entered into between the Qualifying Participant and a member of the Company Group.

Other Agreements. Nothing in the Program is intended to reduce the Company Group’s protections or the employee’s obligations under (i) any other agreement between the employee and
the Company Group, or (ii) any applicable law.

Statute of Limitations. No person may bring any action pertaining to a claim for benefits under the Program following the earlier of (i) 365 days after the final denial of his or her claim for
benefits, or (ii) the limitations period under Delaware contract law.

Governing Law. All provisions of the Program shall be construed in accordance with the laws of the State of Texas, except to the extent preempted by applicable law and except to the
extent that the conflicts of laws provisions of the State of Texas would require the application of the relevant law of another jurisdiction. The venue for any litigation relating to the Program
will be in Harris County, Texas.

Interpretation. Unless expressed otherwise in this Agreement, the term “including” means “including without limitation.” The term “law” includes any (a) law of any jurisdiction (federal,
state, local or other jurisdiction), (b) statutory or common law or (c) applicable regulations.
