2 2016 Annual Report  |  SBA Communications Corporation

SBA  Communications  Corporation  is  a  first  choice 
provider  and  leading  owner  and  operator  of 
wireless communications infrastructure in North, 
Central and South America.

SBA Generates Revenue From Two Primary Businesses:

Site Leasing

Meeting Demand With Wireless Infrastructure

Mobile Data Growth 

■  Projected 47% growth per year in global mobile data traffic over the next five years.*

■  Substantial growth in the number of mobile devices and connections.

■  Cisco predicts mobile video to grow almost 900 percent by 2021.*  

-  Increasingly mobile users want to watch more on-demand video content over the 
Internet. This surge in broadband traffic creates the need for higher speed services 
and more bandwidth. 

Focus on Capacity

Telecom carriers are increasing network capacity to meet the demands of customers 
across their networks. Increasing network capacity means building out or densifying 
their networks.

Deployment of New Spectrum 

Upgrades to our customers’ wireless networks through the deployment of new spectrum 
bands and refarming of 2G and 3G spectrum bands will drive continuing requirements 
for incremental equipment at SBA tower sites.

On the Horizon

The deployment of a nationwide public 
safety  network,  FirstNet,  will  require 
in  wireless 
investment 
significant 
network infrastructure.

Long-Term Growth Potential

Deployment  of  additional  spectrum  represents  long-
term  growth  potential  for  the  wireless  infrastructure 
industry.  Spectrum  bands  still  to  be  deployed  include 
AWS-3, WCS, 2.5 GHz and 600 MHz.

Supporting Future Capacity 

Increased Mobile Activity 

Broadband connectivity is becoming a basic human need, affecting every area of our 
lives  –  businesses,  homes,  schools,  healthcare,  communications  and  entertainment. 
Estimates indicate that by 2021, 5.5 billion members of the global population will be using 
wireless devices.* 

Our size, experience, capabilities and resources make SBA Communications a preferred 
partner for wireless service providers worldwide.

As a global wireless infrastructure operator, SBA will continue to lead the way in providing 
innovative business strategies and continuous improvement to network infrastructure.

to our shareholders:

2016 was another solid and steady year for SBA. 
Throughout  the  year,  we  continued  to  execute 
well  operationally  against  the  constant  backdrop 
of growing wireless demand. Customer activity, in 
the  form  of  organic  growth  through  newly  signed 
leases and amendments, remained comparable to 
2015 levels as our customers remained focused on 
network quality and reliability. During the year, we 
saw continued growth in site leasing revenue, tower 
cash flow, adjusted EBITDA, AFFO and AFFO per 
share.  Also  during  2016,  we  rolled  out  our  long-
term  goal  of  producing  at  least  $10.00  of  AFFO 
per  share  by  2020.  We  take  a  long-term  view  of 
our business, and we believe AFFO per share has 
the greatest impact on shareholder value creation. 
It  underscores  the  strength  of  our  business  and 
long-term  recurring  cash  flow  potential  of  SBA. 
In  order  to  maximize  growth  in  AFFO  per  share, 
we  will  continue  focusing  on  same-tower  organic 
growth,  operational  excellence,  optimizing  our 
capital  structure,  and  a  disciplined  approach  to 
capital allocation.

Steven E. Bernstein 

Organic  growth  continues  to  be  the  top  priority 
for  SBA  as  we  believe  organic  growth  is  the 
most  valuable  type  of  growth  we  can  produce, 
as  it  typically  comes  with  very  little  additional 
capital  investment.  We  ended  2016  with  a  7.0% 
same  tower  year-over-year  gross  organic  leasing 
revenue  growth  rate  in  the  United  States  and 
11.6% for our international business, in both cases 
excluding  the  impact  of  churn.  Organic  growth  is 
primarily  made  up  of  contractual  escalators  and 
new  tenant  leases  and  amendments  to  existing 
sites.  2016  represented  a  steady  and  consistent 
amount  of  new  leasing  activity  in  the  United 
States primarily from the refarming of 2G and 3G 
spectrum  to  LTE,  as  well  as  some  AWS-1  and 
700  MHz  spectrum  deployments.  There  remains 
much additional spectrum to be deployed. Further 
deployments such as AWS-3, WCS, 2.5 GHz, 600 
MHz and FirstNet will require new equipment to 
be  installed  at  existing  and  possibly  new  macro 
sites,  supporting  steady  organic  growth  for 
years to come. International prospects for future 
spectrum deployments and the related need for 
additional  equipment  are  similarly  bright.  We 
believe  the  high  quality  of  our  assets,  exclusive 
nature of our sites, and the critical role our assets 
play  in  our  customers’  wireless  networks  all 
provide a solid foundation for continued organic 
growth moving forward.

To  maximize  the  impact  of  organic  growth,  we 
need  to  execute  well.  We  pride  ourselves  in  our 
operational  execution,  measured  by  our  margin 
performance.  In  2016,  we  posted  the  highest 
EBITDA and tower cash flow margins in company 
history; 69.1% and 79.6%, respectively. We believe 
these margins reflect our ownership of the highest 
quality assets in the industry and our operational 

12

2016 Annual Report  |  SBA Communications Corporation

excellence. We have ample opportunity to expand 
these  margins  in  the  future  through  new  tenant 
revenue additions with very little added expense, 
as  well  as  direct  cost  reductions  through  land 
purchases  and  prepaid  ground  lease  extensions. 
With respect to the latter, in 2016 we spent $66.2 
million  on  land  buyouts,  easements  and  ground 
lease term extensions.

We  continuously  focus  on  optimizing  our  capital 
structure.  Our  balance  sheet  is  in  great  shape 
with plenty of liquidity and financial flexibility. SBA 
continues to be a preferred issuer in the debt capital 
markets as illustrated by the recent securitization 
and  High  Yield  refinancings  we  completed  in 
2016,  both  resulting  in  reduced  coupon  interest 
rates. We reduced our year-end overall weighted 
average cash interest rate by 40 basis points, as 
compared to the end of 2015. Notwithstanding the 

We  also  increased  our  EBITDA  to  cash  interest 
coverage ratio by a half turn compared to the end 
of 2015 to 3.8x. We believe our focus on optimal 
balance  sheet  structure  will  continue  to  be  a 
meaningful driver of value for SBA.

We  believe  we  allocated  capital  wisely  in  2016, 
investing  almost  $900  million  in  new  assets  and 
stock  repurchases.  We  built  372  new  sites  and 
acquired  531  sites,  adding  903  total  sites  to  our 
company  in  2016.  We  ended  the  year  with  over 
26,000 sites owned worldwide. While the number 
of sites added in 2016 is comparatively lower than 
in  years  past,  we  remain  committed  to  achieving 
portfolio growth that meets our investment criteria 
and  is  ultimately  accretive  to  AFFO  per  share. 
While we did not achieve our portfolio growth goals 
of 5% to 10% annually in 2016, it was not because 
of  a  lack  of  opportunities.  We  simply  thought  the 

During  2016,  we  rolled  out  our  long-term  goal  of 
producing at least $10.00 of AFFO per share by 2020.

fact that we operate with materially higher balance 
sheet leverage than our U.S. public tower company 
peers,  we  maintain  one  of  the  lowest  aggregate 
average costs of debt in our industry at 3.5%. We 
continue to feel very confident about how we have 
structured our balance sheet with our current mix 
of debt and equity, staggered debt maturities and 
access to multiple different debt markets. In 2016, 
we raised $1.8 billion in debt financings and ended 
the year with a leverage ratio of 7.6x, just outside 
of our target range of 7.0x to 7.5x net debt to LQA 
EBITDA.  We  ended  the  year  with  a  leverage 
ratio  slightly  above  our  target  range  because  we 
took  advantage  of  some  very  attractive  stock 
repurchase opportunities during the fourth quarter. 

better  decision  long-term  for  our  shareholders 
was  to  pass  on  some  relatively  unattractively 
priced  acquisition  opportunities  and  invest  the 
capital  instead  in  stock  repurchases.  However, 
we  believe  there  will  continue  to  be  many  new 
site  opportunities  available  to  us  and  we  remain 
committed to continuing to grow our portfolio.

While new assets are our first choice for allocating 
capital, we are very disciplined about the price we 
will  pay.  If  we  cannot  find  the  right  opportunities 
at the right prices we will allocate capital towards 
share  buybacks  when  we  believe  our  stock  is 
intrinsically  undervalued.  We  did  just  that  in 
2016.  We  spent  an  aggregate  of  $550  million  on 

2016 Annual Report  |  SBA Communications Corporation

buybacks at an average price of $102.16, which 
we believe to be a terrific value, retiring almost 
5.4  million  shares.  We  will  continue  to  remain 
flexible  and  opportunistic  around  where  we 
allocate our capital. 

Our  international  footprint  continued  to  grow  in 
2016,  including  expanding  into  a  new  market, 
Chile.  Chile  is  a  stable  economy  and  has  many 
needs  for  continued  wireless  investment.  It  has 
familiar,  high  quality  investment  grade  tenants, 
including América Móvil and Telefónica, customers 
that we know very well. We are excited about the 
potential for this new SBA market. In our existing 
international  markets,  we  continued  to  see  a 
healthy mix of amendments and new leases, tilted 
slightly towards new leases. We would expect this 

operations.  We  are  excited  about  the  prospects 
of  continued  portfolio  growth  in  both  our  existing 
international markets and potential new markets.

Approximately 8% of our 2016 total cash site leasing 
revenue,  excluding  pass-through  reimbursable 
expenses,  is  denominated  in  currencies  other 
than the U.S. dollar. Almost all of that revenue was 
generated  in  Brazil.  Foreign  currency  exchange 
volatility  in  Brazil  remained  a  headwind  in  2016, 
although  the  currency  strengthened  during  the 
second  half  of  the  year,  and  has  recently  been 
more stable. On a currency neutral basis, we had 
a steady year, and even saw some increases in 
operational  leasing  activity  in  the  fourth  quarter 
of the year. We continue to remain convinced that 
Brazil  will  be  an  excellent  long-term  investment. 

We believe the high quality of our assets, exclusive nature 
of  our  sites,  and  the  critical  role  our  assets  play  in  our 
customers’  wireless  networks  all provide a solid foundation 
for  continued  organic  growth  moving  forward. 

dynamic to continue as these markets are generally 
less mature and require more points-of-presence 
to provide adequate coverage, similar to the United 
States wireless market of fifteen years ago. While 
our  focus  has  primarily  been  on  the  Western 
Hemisphere, we look at any and all opportunities 
across  the  globe.  For  any  new  market,  we  look 
for  a  number  of  positive  characteristics  before 
we  invest,  such  as  the  need  for  future  wireless 
investment,  the  strength  and  number  of  wireless 
providers,  political  and  currency  stability  and 
our  ability  to  achieve  the  necessary  scale  of  our 

Demographic trends, smartphone sales, network 
needs, new spectrum and the competitive carrier 
dynamic  will  continue  to  support  Brazil  as  a 
growth  market  for  network  investment  for  many 
years to come.

During  2016,  we  began  operating  in  compliance 
with  all  requirements  necessary  to  be  treated 
as  a  Real  Estate  Investment  Trust  (a  “REIT”) 
and,  subsequent  to  year-end,  we  completed  the 
merger of SBA Communications Corporation into 
a  wholly  owned  subsidiary  in  order  to  facilitate 

14

2016 Annual Report  |  SBA Communications Corporation

our  compliance  with  certain  REIT  rules.  We  are 
excited  to  formally  join  the  REIT  community  as 
we  believe  REIT  status  will  be  an  important  step 
in  creating  additional  shareholder  value.  While 
dividends  are  going  to  be  a  part  of  our  future, 
we  will  likely  not  issue  a  dividend  until  we  have 
exhausted  our  existing  net  operating  loss  carry-
forward positions, which are estimated to last four 
to five more years. We do not anticipate our REIT 
tax election to materially change our operations or 
capital allocation decisions in the near term. 

We  are  as  optimistic  about  the  future  as  we 
are  pleased  with  our  past  success  and  value 
creation.  The  future  is  bright,  driven  by  strong 
expectations around growing demand for mobile 
data  services,  particularly  video.  Analysts 
and  prognosticators  all  uniformly  predict 
continued  explosive  growth  in  wireless.  Here 
are a few highlights from Cisco’s annual “Visual 
Networking  Index:  Global  Mobile  Data  Traffic 
Forecast Update, 2016–2021 White Paper”:

■  Global mobile data traffic grew 63% in 2016.

■  Mobile data traffic has grown 18-fold over the 

past five years.

■  Almost  half  a  billion  (429  million)  mobile 
devices and connections were added in 2016.

■  Globally, smart devices represented 46% 
of the total mobile devices and connections 
in 2016.

absence  of  new  spectrum,  through  cell-splitting 
and  densification.  Given  the  strong  anticipated 
demand and the high quality of our assets, we are 
well positioned and intend to remain a key player 
and  partner  in  wireless  network  infrastructure 
around the globe.

In  closing,  I  must  recognize  the  contributions  of 
our  employees  and  customers  to  our  success.  I 
also want to thank you, our shareholders, for your 
continued confidence in and support of SBA. I look 
forward to communicating with you again soon.

mobile data traffic over the next five years.

General

We are a leading independent owner and operator of wireless communications infrastructure, including tower structures,
rooftop, and other structures that support antennas used for wireless communications, which we collectively refer to as “towers” or
“sites.” Our primary business line is our site leasing business, which contributed 98.7% of our total segment operating profit for the
year ended December 31, 2016. In our site leasing business, we (1) lease antenna space to wireless service providers on towers that we
own or operate and (2) manage rooftop and tower sites for property owners under various contractual arrangements. As of December
31, 2016, we owned 26,197 towers, a substantial portion of which have been built by us or built by other tower owners or operators
who, like us, have built such towers to lease space to multiple wireless service providers. We also managed or leased approximately
5,500 actual or potential sites, approximately 500 of which were revenue producing as of December 31, 2016. Our other business line
is our site development business, through which we assist wireless service providers in developing and maintaining their own wireless
service networks. Our principal operations are in the United States and its territories. In addition, we own and operate towers in
Canada, Central America, and South America.

In October 2016, we announced our intention to take the necessary steps to qualify as a Real Estate Investment Trust (“REIT”)
for U.S. federal income tax purposes.  We refer to this as the REIT conversion.  We believe that our business has been operated in a
manner that complies with the REIT rules since January 1, 2016, and as a result, we intend to make the election to be subject to tax as
a REIT commencing with our taxable year ending December 31, 2016.  Because we believe our business is currently operated in a
manner that complies with the REIT rules, no further reorganization of our operations is necessary to complete the REIT conversion.
As part of the REIT conversion, effective January 13, 2017, we completed the merger with our predecessor that was approved by our
shareholders at a special meeting held on January 12, 2017. As a result of the merger, we now hold, directly or indirectly through our
subsidiaries, the assets held by our predecessor prior to the merger and conduct the existing businesses of our predecessor and its
subsidiaries.  Although the REIT rules do not require the completion of this merger, we completed the merger to facilitate our
compliance with the REIT rules by ensuring the effective adoption of certain REIT-related ownership limitations and transfer
restrictions related to our capital stock.  See “Management’s Discussion and Analysis of Financial Condition and Results of
Operation—REIT Conversion” for more information.

Site Leasing Services

Our primary focus is the leasing of antenna space on our multi-tenant towers to a variety of wireless service providers under

long-term lease contracts in the United States, Canada, Central America, and South America. We derive site leasing revenues
primarily from wireless service provider tenants, including AT&T, T-Mobile, Sprint, Verizon Wireless, Oi S.A., Telefonica, Claro,
and TIM. Wireless service providers enter into tenant leases with us, each of which relates to the lease or use of space at an individual
site. Our site leasing business generates substantially all of our total segment operating profit, representing 96.3% or more of our total
segment operating profit for the past three fiscal years. Our site leasing business is classified into two reportable segments, domestic
site leasing and international site leasing.

Domestic Site Leasing

As of December 31, 2016, we owned 15,922 sites in the United States and its territories.  For the year ended December 31,
2016, we generated 82.8% of our total site leasing revenue from these sites. We derive domestic site leasing revenues primarily from
AT&T, T-Mobile, Sprint, and Verizon Wireless. Wireless service providers enter into tenant leases with us, each of which relates to
the lease or use of space at each individual site. In the United States, our tenant leases are generally for an initial term of five to ten
years with five 5-year renewal periods at the option of the tenant. These tenant leases typically contain specific rent escalators, which
average 3-4% per year, including the renewal option periods. Our ground leases in the United States are generally for an initial term of
five years or more with multiple renewal terms of five-year periods at our option and provide for rent escalators which typically
average 2-3% annually. As of December 31, 2016, (1) no U.S. state or territory included more than 10% of our total tower portfolio by
tower count, and (2) no U.S. state or territory accounted for more than 10% of our total revenues for the year ended December 31,
2016.

International Site Leasing

We continue to focus on growing our international site leasing business through the acquisition and development of towers. We

believe that we can create substantial value by expanding our site leasing services into select international markets which we believe
have a high-growth wireless industry and relatively stable political and regulatory environments. As of December 31, 2016, we owned

1

10,275 towers in our international markets, including Canada, Central America, and South America. Approximately 28% of our total
towers are located in Brazil and less than 3% of our total towers are located in each of our other international markets (each country is
considered a market). We derive international site leasing revenues primarily from Oi S.A., Telefonica, Claro, and TIM. Our
operations in these countries are solely in the site leasing business, and we expect to continue to expand operations through
acquisitions and new builds.

In Canada, our tenant leases are generally for an initial term of five to ten years with five 5-year renewal periods at the option of

the tenant. These tenant leases typically contain specific rent escalators, which average 3-4% per year, including the renewal option
periods. Tenant leases in our Central American and South American markets typically have an initial term of ten years with multiple
five year renewal periods. In Central America, we have similar fixed rent escalators to that of leases in the United States and Canada
while our leases in South America escalate in accordance with a standard cost of living index. In Brazil, tenant leases are typically
governed by master lease agreements, which provide for the material terms and conditions that will govern the terms of the use of the
site. Tenant leases in South America typically provide for a fixed rental amount and a pass-through charge for the underlying ground
lease rent.  Our ground leases in Canada, Central America and South America generally have similar terms and conditions as those in
the United States, except that the annual escalators in our South American ground leases are based on a cost of living index. Our
operations in Central America and Ecuador are primarily denominated in United States Dollars, while our operations in Canada and
the remainder of South America are denominated in local currencies.

Domestic and International Expansion

We expand our tower portfolio, both domestically and internationally, through the acquisition of towers from third parties and

through the construction of new tower structures. In our tower acquisition program, we pursue towers that meet or exceed our internal
guidelines regarding current and future potential returns. For each acquisition, we prepare various analyses that include projections of
a five-year unlevered internal rate of return, review of available capacity, future lease up projections, and a summary of current and
future tenant/technology mix.

The majority of our international markets typically have less mature wireless networks with limited wireline infrastructure and
lower wireless data penetration rates than those in the United States. Accordingly, our expansion in these markets is primarily driven
by (i) wireless service providers seeking to increase the quality and coverage of their networks, (ii) increased consumer mobile data
traffic, such as media streaming, mobile apps and games, web browsing, and email, and (iii) incremental spectrum auctions, which
have resulted in new market entrants, as well as incremental voice and data network deployments. Since we first entered the Central
and South American markets, we have built or acquired 10,003 towers as of December 31, 2016 and continue to expand in these
markets to respond to growing demand.

We consider various factors when identifying a market for our international expansion, including:

•

Country analysis – We consider the country’s economic and political stability, and whether the country’s general business,
legal and regulatory environment is conducive to the sustainability and growth of our business.

• Market potential – We analyze the expected demand for wireless services, and whether a country has multiple wireless

•

service providers who are actively seeking to invest in deploying voice and data networks, as well as spectrum auctions that
have occurred or that are anticipated to occur.
Risk adjusted return criteria – We consider whether buying or building towers in a country, and providing our management
and leasing services, will meet our return criteria. As part of this analysis, we consider the risk of entering into an
international market (for example, the impact of foreign currency exchange rates, real estate, permitting, and taxation risks),
and how our expansion meets our long-term strategic objectives for the region and our business generally.

In our new build program, we construct tower structures (1) in locations that are strategically chosen by us or (2) under build-to-

suit arrangements. Under build-to-suit arrangements, we build tower structures for wireless service providers at locations that they
have identified. Under these arrangements, we retain ownership of the tower structure and the exclusive right to co-locate additional
tenants. When we construct tower structures in locations chosen by us, we utilize our knowledge of our customers’ network
requirements to identify locations where we believe multiple wireless service providers need, or will need to locate antennas to meet
capacity or service demands. We seek to identify attractive locations for new tower structures and complete pre-construction
procedures necessary to secure the site concurrently with our leasing efforts. We generally will have at least one signed tenant lease
for each new build tower structure on the day that it is completed and expect that some will have multiple tenants.

Site Development Services

Our site development business, which is conducted in the United States only, is complementary to our site leasing business and

provides us the ability to keep in close contact with the wireless service providers who generate substantially all of our site leasing
revenue and to capture ancillary revenues that are generated by our site leasing activities, such as antenna and equipment installation
at our tower locations. Site development services revenues are earned primarily from providing a full range of end to end services to
wireless service providers or companies providing development or project management services to wireless service providers. Our
services include: (1) network pre-design; (2) site audits; (3) identification of potential locations for towers and antennas on existing
infrastructure; (4) support in leasing of the location; (5) assistance in obtaining zoning approvals and permits; (6) tower and related
site construction; (7) antenna installation; and (8) radio equipment installation, commissioning, and maintenance. We provide site
development services at our towers and at towers owned by others on a local basis, through regional, market, and project offices. The
market offices are responsible for all site development operations.

For financial information about our operating segments, please see Note 18 of our Consolidated Financial Statements included

in this Form 10-K.

Industry Developments

We believe that growing wireless traffic (particularly data and video), the deployment of additional spectrum, and technology

advancements will require wireless service providers to improve their network infrastructure and increase their network capacity
resulting in an increase in the number of towers that they utilize and additions or changes to the equipment they deploy at existing
towers. We expect that the wireless communications industry will continue to experience growth as a result of the following trends:

•

•

•

•

As wireless data traffic continues to grow, carriers are investing to increase the capacity of their networks; and we believe
that the continued capacity increases will require our customers to add additional cell sites and additional new equipment at
current cell sites.

Spectrum licensed by the Federal Communications Commission (the “FCC”) has enabled continued network development.
We expect the deployment of currently fallow spectrum and the availability of additional spectrum through a government
auction anticipated to be completed in 2017 to drive continued network development in the U.S.

Consumers are increasing their demand for wireless connectivity due to expansion of wireless data applications, such as
video, mobile apps and games, web browsing, email and social networking, and continued wireline to wireless migration.
Wireless devices such as smartphones, tablets, laptops, and other emerging and embedded devices continue to trend toward
being more bandwidth-intensive. As a result, according to industry estimates, global mobile data traffic will grow at an
approximately 47% compound annual growth rate from 2016 to 2021 and will grow at a rate three times faster than non-
mobile data traffic over the same period.

Consumers list network quality as a key contributor when terminating or changing service. To decrease subscriber churn
rate, wireless carriers have made substantial capital expenditures on wireless networks to improve service quality and
expand coverage. We expect U.S. wireless carriers to continue to expend capital for the foreseeable future in order to
continue to improve their networks.

We believe that the world-wide wireless industry will continue to grow and is reasonably well-capitalized, highly competitive

and focused on quality and advanced services. Therefore, we expect that we will see a multi-year trend of additional demand for tower
space from our customers, which we believe will translate into steady leasing growth for us.

Business Strategy

Our primary strategy is to continue to focus on expanding our site leasing business due to its attractive characteristics such as
long-term contracts, built-in rent escalators, high operating margins, and low customer churn (which refers to when a customer does
not renew its lease, or, in very limited circumstances, such as in a customer bankruptcy, cancels its lease prior to the end of its term)
other than in connection with customer consolidation or cessation of a particular technology (e.g. iDEN). The long-term and repetitive
nature of the revenue stream of our site leasing business makes it less volatile than our site development business, which is more
cyclical. By focusing on our site leasing business, we believe that we can maintain a stable, recurring cash flow stream and reduce our
exposure to cyclical changes in customer spending. Key elements of our strategy include:

Maximizing Use of Tower Capacity. We generally have constructed or acquired towers that accommodate multiple tenants and a

majority of our towers are high capacity tower structures. Most of our towers have significant capacity available for additional
antennas, and we believe that increased use of our towers can be achieved at a low incremental cost. We measure the available

3

capacity of our existing facilities to support additional tenants and generate additional lease revenue by assessing several factors,
including tower height, tower type, wind loading, environmental conditions, existing equipment on the tower and zoning and
permitting regulations in effect in the jurisdiction where the tower is located. We actively market space on our towers through our
internal sales force. As of December 31, 2016, we had an average of 1.8 tenants per tower structure.

Disciplined Growth of our Tower Portfolio. We believe that our tower operations are highly scalable. Consequently, we believe

that we are able to materially increase our tower portfolio without proportionately increasing selling, general, and administrative
expenses. We intend to continue to grow our tower portfolio, domestically and internationally, through tower acquisitions and the
construction of new tower structures. In connection with our international expansion, we have targeted select international markets
that we believe have relatively stable political environments and a growing wireless communications industry. We intend to use our
available cash from operating activities and available liquidity, including borrowings, to build and/or acquire new towers at prices that
we believe will be accretive to our shareholders both in the short and long term and which allow us to maintain our long-term target
leverage ratios.

Capitalizing on our Scale and Management Experience. We are a large owner, operator and developer of towers, with
substantial capital, human, and operating resources. We have been developing towers for wireless service providers in the U.S. since
1989 and owned and operated towers for ourselves since 1997. We believe our size, experience, capabilities, and resources make us a
preferred partner for wireless service providers both in the U.S. and internationally. Our management team has extensive experience in
site leasing and site development, with some of the longest tenures in the tower and site development industries. We believe that our
industry expertise and strong relationships with wireless service providers will allow us to expand our position as a leading provider of
site leasing and site development services.

Controlling our Underlying Land Positions. We have purchased and/or entered into perpetual easements or long-term leases for
the land that underlies our tower structures and intend to continue to do so, to the extent available at commercially reasonable prices.
We believe that these purchases, perpetual easements, and/or long-term leases will increase our margins, improve our cash flow from
operations, and minimize our exposure to increases in ground lease rents in the future. As of December 31, 2016, approximately 72%
of our tower structures were located on land that we own or control for more than 20 years and the average remaining life under our
ground leases, including renewal options under our control, was 33 years. As of December 31, 2016, approximately 6.2% of our tower
structures had ground leases maturing in the next 10 years.

Using our Local Presence to Build Strong Relationships with Major Wireless Service Providers. Given the nature of towers as

location-specific communications facilities, we believe that substantially all of what we do is done best locally. Consequently, we
have a broad field organization that allows us to develop and capitalize on our experience, expertise and relationships in each of our
local markets which in turn enhances our customer relationships. We are seeking to replicate this operating model internationally. Due
to our presence in local markets, we believe we are well positioned to capture additional site leasing business and new tower build
opportunities in our markets and identify and participate in site development projects across our markets.

Customers

Since commencing operations, we have performed site leasing and site development services for all of the large U.S. wireless

service providers. In both our site leasing and site development businesses, we work with large national providers and smaller
regional, local, or private operators. Internationally, we service all the major service providers in Canada, Central America, and South
America.

We depend on a relatively small number of customers for our site leasing and site development revenues. The following

customers represented at least 10% of our total revenues during the last three years:

Sales and Marketing

Our sales and marketing goals are to:

•

•

use existing relationships and develop new relationships with wireless service providers to lease antenna space on and sell
related services with respect to our owned or managed towers, enabling us to grow our site leasing business; and

successfully bid and win those site development services contracts that will contribute to our operating margins and/or
provide a financial or strategic benefit to our site leasing business.

We approach sales on a company-wide basis, involving many of our employees. We have a dedicated sales force that is

supplemented by members of our executive management team. Our dedicated salespeople are based regionally as well as in our
corporate office. We also rely on our vice presidents, general managers, and other operations personnel to sell our services and
cultivate customers. Our strategy is to delegate sales efforts by geographic region or to those employees of ours who have the best
relationships with our customers. Most wireless service providers have national corporate headquarters with regional and local offices.
We believe that wireless service providers make most decisions for site development and site leasing services at the regional and local
levels with input from their corporate headquarters. Our sales representatives work with wireless service provider representatives at
the regional and local levels and at the national level when appropriate. Our sales staff’s compensation is heavily weighted to
incentive-based goals and measurements.

Competition

Domestic Site Leasing – In the U.S., our primary competitors for our site leasing activities are (1) the national independent
tower companies including American Tower Corporation and Crown Castle International, (2) a large number of regional independent
tower owners, (3) wireless service providers that own and operate their own towers and lease, or may in the future decide to lease,
antenna space to other providers, and (4) alternative facilities such as rooftops, outdoor and indoor distributed antenna system
(“DAS”) networks, billboards, utility poles, and electric transmission towers. American Tower and Crown Castle have significantly
more towers than we do, which could provide them a competitive advantage in negotiating with wireless service providers.
Furthermore, these entities generally have greater financial resources than we do which may provide them with a competitive
advantage in connection with the acquisition of material tower portfolios. However, we believe that tower location and capacity have
been and will continue to be the most significant competitive factors affecting the site leasing business. Other competitive factors are
quality of service to our tenants and price.

International Site Leasing – Our competition consists of wireless service providers that own and operate their own tower
networks, large national and regional independent tower companies, and alternative facilities such as rooftop, outdoor and indoor DAS
networks, billboards, utility poles, and electric transmission towers.

Site Development – The site development business is extremely competitive and price sensitive. We believe that the majority of

our competitors in the U.S. site development business operate within local market areas exclusively, while some firms offer their
services nationally. The market includes participants from a variety of market segments offering individual, or combinations of,
competing services. The field of competitors includes site development consultants, zoning consultants, real estate firms, right-of-way
consulting firms, construction companies, tower owners/managers, radio frequency engineering consultants, telecommunications
equipment vendors, which provide end-to-end site development services through multiple subcontractors, and wireless service
providers’ internal staff. We believe that providers base their decisions for site development services on a number of criteria, including
company experience, price, track record, local reputation, geographic reach, and time for completion of a project.

5

Employees

Our corporate offices are located in our headquarters in Boca Raton, Florida. We also have employees located in our

international, regional, and local offices. As of December 31, 2016, we had 1,241 employees of which 253 were based outside of the
U.S. and its territories. We consider our employee relations to be good.

Regulatory and Environmental Matters

Federal Regulations. In the U.S., which accounted for 82.8% of our total site leasing revenue for the year ended December 31,
2016, both the FCC and the Federal Aviation Administration (the “FAA”) regulate towers. Many FAA requirements are implemented
in FCC regulations. These regulations, which were amended in 2014, govern the construction, lighting, and painting or other marking
of towers, as well as the maintenance, inspection, and record keeping related to towers, and may, depending on the characteristics of
particular towers, require prior approval and registration of towers before they may be constructed, altered or used. Wireless
communications equipment and radio or television stations operating on towers are separately regulated and may require independent
customer licensing depending upon the particular frequency or frequency band used. In addition, any applicant for an FCC tower
structure registration (through the FCC’s Antenna Structure Registration System) must certify that, consistent with the Anti-Drug
Abuse Act of 1988, neither the applicant nor its principals are subject to a denial of federal benefits because of a conviction for the
possession or distribution of a controlled substance. New tower construction also requires approval from the state or local governing
authority for the proposed site: compliance with the National Environmental Policy Act (“NEPA”); compliance with the National
Historic Preservation Act (“NHPA”); compliance with the Endangered Species Act (“ESA”); and may require notification to the FAA.

Pursuant to the requirements of the Communications Act of 1934, as amended, the FCC, in conjunction with the FAA, has

developed standards to consider proposals involving new or modified towers. These standards mandate that the FCC and the FAA
consider the height of the proposed tower, the relationship of the tower to existing natural or man-made obstructions, and the
proximity of the tower to runways and airports. Proposals to construct or to modify existing towers above certain heights must be
reviewed by the FAA to ensure the structure will not present a hazard to air navigation. The FAA may condition its issuance of a no-
hazard determination upon compliance with specified lighting and/or painting requirements. Towers that meet certain height and
location criteria must also be registered with the FCC. A tower that requires FAA clearance will not be registered by the FCC until it
is cleared by the FAA. Upon registration, the FCC may also require special lighting and/or painting. Owners of wireless
communications towers may have an obligation to maintain painting and lighting or other marking in conformance with FAA and
FCC regulations. Tower owners and licensees that operate on those towers also bear the responsibility of monitoring any lighting
systems and notifying the FAA of any lighting outage or malfunction.

Owners and operators of towers may be subject to, and therefore must comply with, environmental laws, including NEPA,

NHPA and ESA. Any licensed radio facility on a tower is subject to environmental review pursuant to the NEPA, among other
statutes, which requires federal agencies to evaluate the environmental impact of their decisions under certain circumstances. The FCC
has issued regulations implementing the NEPA. These regulations place responsibility on applicants to investigate potential
environmental effects of their operations and to disclose any potential significant effects on the environment in an environmental
assessment prior to constructing or modifying a tower and prior to commencing certain operations of wireless communications or
radio or television stations from the tower. In the event the FCC determines the proposed structure or operation would have a
significant environmental impact based on the standards the FCC has developed, the FCC would be required to prepare an
environmental impact statement, which will be subject to public comment. This process could significantly delay the registration of a
particular tower.

We generally indemnify our customers against any failure to comply with applicable regulatory standards relating to the
construction, modification, or placement of towers. Failure to comply with the applicable requirements may lead to civil penalties.

The Telecommunications Act of 1996 amended the Communications Act of 1934 by preserving state and local zoning

authorities’ jurisdiction over the construction, modification, and placement of towers. The law, however, limits local zoning authority
by prohibiting any action that would discriminate among different providers of personal wireless services or ban altogether the
construction, modification or placement of radio communication towers. Finally, the Telecommunications Act of 1996 requires the
federal government to help licensees for wireless communications services gain access to preferred sites for their facilities. This may
require that federal agencies and departments work directly with licensees to make federal property available for tower facilities.

As an owner and 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 and related personal injury or property damage. We are also subject to
certain environmental laws that govern tower placement and may require pre-construction environmental studies. Operators of towers
must also take into consideration certain radio frequency (“RF”) emissions regulations that impose a variety of procedural and

6

operating requirements. Certain proposals to operate wireless communications and radio or television stations from tower structures
are also reviewed by the FCC to ensure compliance with requirements relating to human exposure to RF emissions. Exposure to high
levels of RF energy can produce negative health effects. The potential connection between low-level RF energy 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 believe that we are in substantial compliance with and we have no material liability under any applicable environmental laws.
These costs of compliance with existing or future environmental laws and liability related thereto may have a material adverse effect
on our prospects, financial condition or results of operations.

State and Local Regulations. Most states regulate certain aspects of real estate acquisition, leasing activities, and construction
activities. Where required, we conduct the site acquisition portions of our site development services business through licensed real
estate brokers’ agents, who may be our employees or hired as independent contractors, and conduct the construction portions of our
site development services through licensed contractors, who may be our employees or independent contractors. Local regulations
include city and other local ordinances, zoning restrictions and restrictive covenants imposed by community developers. These
regulations vary greatly from jurisdiction to jurisdiction, but typically require tower owners to obtain approval from local officials or
community standards organizations, or certain other entities prior to tower construction and establish regulations regarding
maintenance and removal of towers. In addition, many local zoning authorities require tower owners to post bonds or cash collateral to
secure their removal obligations. Local zoning authorities generally have been unreceptive to construction of new towers in their
communities because of the height and visibility of the towers, and have, in some instances, instituted moratoria.

International. Regulatory regimes outside of the U.S. and its territories vary by country and locality; however, these regulations

typically require tower owners and/or licensees to obtain approval from local officials or government agencies prior to tower
construction or modification or the addition of a new antenna to an existing tower. Additionally, some regulations include ongoing
obligations regarding painting, lighting, and maintenance. Our international operations may also be subject to limitations on foreign
ownership of land in certain areas. Based on our experience to date, these regimes have been similar to, but not more rigorous,
burdensome or comprehensive than, those in the U.S. Non-compliance with such regulations may lead to monetary penalties or
deconstruction orders. Our international operations are also subject to various regulations and guidelines regarding employee relations
and other occupational health and safety matters. As we expand our operations into additional international geographic areas, we will
be subject to regulations in these jurisdictions.

Backlog

Backlog related to our site leasing business consists of lease agreements and amendments, which have been signed, but have not

yet commenced. As of December 31, 2016, we had 955 new leases and amendments which had been executed with customers but
which had not begun generating revenue. These leases and amendments will contractually provide for approximately $8.7 million of
annual revenue. By comparison, as of December 31, 2015, we had 697 new leases and amendments which had been executed with
customers but which had not begun generating revenue. These leases and amendments contractually provided for approximately $6.6
million of annual revenue.

Our backlog for site development services consists of the value of work that has not yet been completed under executed
contracts. As of December 31, 2016, we had approximately $26.0 million of contractually committed revenue as compared to
approximately $30.7 million as of December 31, 2015.

ITEM 1A. RISK FACTORS

Risks Related to Our Business

If our wireless service provider customers combine their operations to a significant degree, our future operating results, ability to
service our indebtedness, and stock price could be adversely affected.

Significant consolidation among our wireless service provider customers may result in our customers failing to renew existing

leases for tower space or reducing future capital expenditures in the aggregate because their existing networks and expansion plans
may overlap or be very similar, or acquired technologies may be discontinued. In connection with the combinations of Verizon
Wireless and ALLTEL (to form Verizon Wireless), Cingular and AT&T Wireless (to form AT&T Mobility) and Sprint PCS and
Nextel (to form Sprint), the combined companies have rationalized duplicative parts of their networks, and, in the case of Sprint, the
Nextel iDEN network was discontinued, which has led and may continue to lead to the non-renewal of certain leases on our towers.
During 2013, Sprint acquired Clearwire Communications and T-Mobile acquired MetroPCS, and in 2014, AT&T acquired Leap
Wireless (Cricket Wireless). These consolidations have led and may also lead to additional non-renewal of certain of our tower leases.
If our wireless service provider customers continue to consolidate as a result of, among other factors, limited wireless spectrum for
commercial use in the U.S., these consolidations could significantly impact the number of tower leases that are not renewed or the
number of new leases that our wireless service provider customers require to expand their networks, which could materially and
adversely affect our future operating results and our ability to service our indebtedness. These risks could be exacerbated due to
changes in governmental policy that may favor industry consolidation.

In addition, the market price of our Class A common stock may be affected by the economic and market perception of the
announcement or consummation of wireless service provider customer consolidations and their impact on our future operating results.

We have a substantial level of indebtedness which may have an adverse effect on our business or limit our ability to take advantage
of business, strategic or financing opportunities.

As indicated below, we have and will continue to have a significant amount of indebtedness relative to our deficit. The

following table sets forth our total principal amount of debt and shareholders’ deficit as of December 31, 2016 and 2015.

Our substantial level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay the
principal, interest, or other amounts due on our indebtedness. Subject to certain restrictions under our existing indebtedness, we and
our subsidiaries may also incur significant additional indebtedness in the future, some of which may be secured debt. This may have
the effect of increasing our total leverage. For example, on July 7, 2016, we, through a New York common law trust, issued $700.0
million aggregate principal amount of Tower Securities, and on August 15, 2016, we issued $1.1 billion of unsecured senior notes.

As a consequence of our indebtedness, (1) demands on our cash resources may increase, (2) we are subject to restrictive
covenants that further limit our financial and operating flexibility and (3) we may choose to institute self-imposed limits on our
indebtedness based on certain considerations including market interest rates, our relative leverage and our strategic plans. For
example, as a result of our substantial level of indebtedness and the uncertainties arising in the credit markets and the U.S. economy:

•

•

•

we may be more vulnerable to general adverse economic and industry conditions;

we may have to pay higher interest rates upon refinancing or on our variable rate indebtedness if interest rates rise,
thereby reducing our cash flows;

we may find it more difficult to obtain additional financing to fund future working capital, capital expenditures and other
general corporate requirements that would be in our best long-term interests;

8

•

•

•

•

we may be required to dedicate a substantial portion of our cash flow from operations to the payment of principal and
interest on our debt, reducing the available cash flow to fund other investments, including share repurchases, tower
acquisition and new build capital expenditures, or to satisfy our REIT distribution requirements;

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 that are less leveraged; and

we may be required to sell debt or equity securities or sell some of our core assets, possibly on unfavorable terms, in order
to meet payment obligations.

These restrictions could have a material adverse effect on our business by limiting our ability to take advantage of financing,

new tower development, mergers and acquisitions, share repurchases, or other opportunities and to satisfy our REIT distribution
requirements.

In addition, fluctuations in market interest rates or changes in central bank monetary policy may increase interest expense

relating to our floating rate indebtedness, which we expect to incur pursuant to our Revolving Credit Facility and Term Loans, and
may make it difficult to refinance our existing indebtedness at a commercially reasonable rate or at all. There is no guarantee that the
future refinancing of our indebtedness will have fixed interest rates or that interest rates on such indebtedness will be equal to or lower
than the rates on our current indebtedness.

We depend on a relatively small number of customers for most of our revenue, and the loss, consolidation or financial instability of
any of our significant customers may materially decrease our revenue and adversely affect our financial condition.

We derive a significant portion of our revenue from a small number of customers. Consequently, a reduction in demand for site

leasing, reduced future capital expenditures on the networks, or the loss, as a result of bankruptcy, merger with other customers of
ours or otherwise, of any of our largest customers could materially decrease our revenue and have an adverse effect on our growth.

On June 20, 2016, Oi, S.A. (“Oi”), our largest customer in Brazil, filed a petition for judicial reorganization in Brazil. For the

year ended December 31, 2016, Oi comprised approximately 7.5% of our total site leasing revenue. Due to the uncertainty
surrounding the recoverability of amounts owed by Oi prior to the date of Oi’s petition, we recorded a $16.5 million bad debt
provision during the second quarter of 2016 relating to amounts owed or potentially owed by Oi as of the petition date. While we
continue to do business with Oi under our contracts in the ordinary course and Oi has stated its intentions to continue normal
operations during its judicial reorganization, we cannot assure you that Oi will continue to be willing or able to continue to make
payments to us in accordance with the terms of our contracts. Judicial reorganization in Brazil requires the agreement of certain
creditors, for which there can be no assurance. If Oi is unable to successfully reorganize, it may be forced to liquidate. If Oi is unable
or unwilling to reorganize in a manner that continues to provide us anticipated payments in accordance with our contracts, it could
materially decrease our revenues and adversely affect our financial condition.

The following is a list of significant customers (representing at least 10% of revenue in any of the last three years) and the

Prior year amounts have been adjusted to reflect the merger of AT&T Wireless and Leap Wireless (Cricket Wireless).

We derive revenue through numerous site leasing contracts and site development contracts. Each site leasing contract relates to
the lease of space at an individual tower and is generally for an initial term of five to ten years in the U.S. and Canada, and renewable
for five 5-year periods at the option of the tenant. Site leasing contracts in our Central American and South American markets
typically have an initial term of ten years with multiple five year renewal periods. However, if any of our significant site leasing
customers were to experience financial difficulty, substantially reduce their capital expenditures or reduce their dependence on leased
tower space and fail to renew their leases with us, our revenues, future revenue growth and results of operations would be adversely
affected.

Our site development customers engage us on a project-by-project basis, and a customer can generally terminate an assignment
at any time without penalty. In addition, a customer’s need for site development services can decrease, and we may not be successful
in establishing relationships with new customers. Furthermore, our existing customers may not continue to engage us for additional
projects.

Currency fluctuations may negatively affect our results of operations.

We have business operations in Canada, Central America, and South America.  Our operations in Central America and Ecuador

are primarily denominated in United States dollars, while our operations in Canada and the remainder of South America are
denominated in local currencies.  Our foreign currency denominated revenues and expenses are translated into United States dollars at
applicable exchange rates for inclusion in our consolidated financial statements.

For the year ended December 31, 2016, approximately 16.3% of our total cash site leasing revenue was generated by our

international operations, of which 11.6% was generated in non-U.S. dollar currencies, including 10.8% which was denominated in
Brazilian Real. The exchange rates between our foreign currencies and the United States Dollar have fluctuated significantly recently
and may continue to do so in the future.  For example, the Brazilian Real has historically been subject to substantial volatility and
weakened 5.5% when comparing the average rate for the years ended December 31, 2016 and 2015. This trend has affected, and may
in the future continue to affect, our reported results of operations.

Changes in exchange rates between these local currencies and the United States dollar will affect the recorded levels of site
leasing revenue, segment operating profit, assets and/or liabilities. Volatility in foreign currency exchange rates can also affect our
ability to plan, forecast and budget for our international operations and expansion efforts.

10

Furthermore, we have an intercompany loan agreement which permits one of our Brazilian entities to borrow amounts up to
$750.0 million. As of December 31, 2016, the outstanding balance under this agreement was $433.3 million. In accordance with ASC
830, we remeasure foreign denominated intercompany loans with the corresponding change in the balance being recorded in Other
income (expense), net in our Consolidated Statements of Operations as settlement is anticipated or planned in the foreseeable future.
Consequently, if the U.S. Dollar strengthens against the Brazilian Real, our results of operations would be adversely affected. For the
years ended December 31, 2016 and 2015, we recorded a $90.0 million gain and a $178.9 million loss, respectively, on
remeasurement of the intercompany loan due to changes in foreign currency exchange rates.

If we are unable to protect our rights to the land under our towers, it could adversely affect our business and operating results.

Our real property interests relating to the land under our tower structures consist primarily of leasehold and sub-leasehold
interests, fee interests, easements, licenses, rights-of-way, and other similar interests. From time to time, we experience disputes with
landowners regarding the terms of the agreements for the land under our tower structures, which can affect our ability to access and
operate such towers. Further, landowners may not want to renew their agreements with us, they may lose their rights to the land, or
they may transfer their land interests to third parties, including ground lease aggregators and our competitors, which could affect our
ability to renew agreements on commercially viable terms or at all. In addition, the land underlying the 2,113 towers we acquired in
2013 from Oi, one of Brazil’s largest telecommunications providers, is subject to a concession from the Federal Republic of Brazil
that expires in 2025.  At the end of the term, the Brazilian government will have the right to (i) renew the concession upon newly
negotiated terms or (ii) terminate the concession and take possession of the land and the tower on such land.  Although Oi has entered
into a non-terminable lease with us for 35 years, if the concession is not renewed, our site leasing revenue from co-located tenants
would terminate prior to the end of such lease. For the year ended December 31, 2016, we generated 12.0% of our total international
site leasing revenue from these 2,113 towers of which 7.4% related to Oi and 4.6% represented revenue from co-located tenants.

As of December 31, 2016, the average remaining life under our ground leases, including renewal options under our control, was
approximately 33 years, and approximately 6.2% of our tower structures have ground leases maturing in the next 10 years.  Failure to
protect our rights to the land under our towers may have a material adverse effect on our business, results of operations or financial
condition.

New technologies or network architecture or changes in a customer’s business model may reduce demand for our wireless
infrastructure or negatively impact our revenues.

Improvements or changes in the efficiency, architecture, and design of wireless networks or changes in a wireless service
provider customer’s business model may reduce the demand for our wireless infrastructure. In addition, as customers deploy increased
capital to the development and implementation of new technologies, they may allocate less of their budgets to lease space on our
towers. For example, new technologies that may promote network sharing, joint development, or resale agreements by our wireless
service provider customers, such as signal combining technologies or network functions virtualization, may reduce the need for our
wireless infrastructure. In addition, other technologies and architectures, such as WiFi, DAS, femtocells, other small cells, or satellite
(such as low earth orbiting) and mesh transmission systems may, in the future, serve as substitutes for, or alternatives to, the
traditional macro site cellular architecture that is the basis of substantially all of our site leasing business. In addition, new
technologies that enhance the range, efficiency, and capacity of wireless equipment could reduce demand for our wireless
infrastructure. Further, a customer may decide to no longer outsource wireless infrastructure or otherwise change its business model.
Any significant reduction in demand for our wireless infrastructure resulting from new technologies or new architectures or changes in
a customer’s business model may negatively impact our revenues or otherwise have a material adverse effect on us.

Increasing competition may negatively impact our ability to grow our communication site portfolio long term.

We intend to continue growing our tower portfolio, domestically and internationally, through acquisitions and new builds. Our

ability to meet our growth targets significantly depends on our ability to build or acquire existing towers that meet our investment
requirements. Traditionally, our acquisition strategy has focused on acquiring towers from smaller tower companies, independent
tower developers and wireless service providers. However, as a result of consolidation in the tower industry there are fewer of these
mid-sized tower transactions available in the U.S. and there is more competition to acquire existing towers. Increased competition for
acquisitions may result in fewer acquisition opportunities for us, higher acquisition prices, and increased difficulty in negotiating and
consummating agreements to acquire such towers. For example, in 2016, we passed on more U.S. acquisitions than we did in 2015
due to asset quality, price, or lease terms. Furthermore, to the extent that the tower acquisition opportunities are for significant tower
portfolios, many of our competitors are significantly larger and have greater financial resources than we do. Finally, competition
regulations, domestically and internationally, may limit our ability to acquire certain portfolios or apply to us differently than they
apply to our competitors.  As a result of these risks, the cost of acquiring these towers may be higher than we expect or we may not be

11

able to meet our annual and long-term tower portfolio growth targets. If we are not able to successfully address these challenges, we
may not be able to materially increase our tower portfolio in the long-term.

Our ability to build new towers is dependent upon the availability of sufficient capital to fund construction, our ability to locate,
and acquire at commercially reasonable prices, attractive locations for such towers and our ability to obtain the necessary zoning and
permits. Local regulations, including municipal or local ordinances, zoning restrictions and restrictive covenants imposed by
community developers, vary greatly, but typically require antenna tower and structure owners to obtain approval from local officials
or community standards organizations prior to tower or structure construction or modification.  With respect to our international new
builds, our tower construction may be delayed or halted as a result of local zoning restrictions, inconsistencies between laws or other
barriers to construction in international markets. Due to these risks, it may take longer to complete our new tower builds, domestically
and internationally, than anticipated, the costs of constructing these towers may be higher than we expect or we may not be able to add
as many towers as we had planned in 2017. If we are not able to increase our tower portfolio as anticipated, it could negatively impact
our ability to achieve our financial goals.

Our international operations are subject to economic, political and other risks that could materially and adversely affect our
revenues or financial position.

Our current business operations in Canada, Central America, and South America, and our expansion into any other international
markets in the future, could result in adverse financial consequences and operational problems not typically experienced in the United
States. The consolidated revenues generated by our international operations were approximately 16.2% during the year ended
December 31, 2016, and we anticipate that our revenues from our international operations will continue to grow in the future.
Accordingly, our business is and will in the future be subject to risks associated with doing business internationally, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

changes in a specific country’s or region’s political or economic conditions;

laws and regulations that tax or otherwise restrict repatriation of earnings or other funds or otherwise limit distributions of
capital;

laws and regulations that dictate how we operate our towers and conduct business, including zoning, maintenance and
environmental matters, and laws related to ownership of real property;

laws and regulations governing our employee relations, including occupational health and safety matters;

changes to existing or new domestic or international tax laws or fees directed specifically at the ownership and operation
of towers, which may be applied and enforced retroactively;

expropriation and governmental regulation restricting foreign ownership;

laws effecting telecommunications infrastructure including the sharing of such infrastructure;

restriction or revocation of spectrum licenses;

our ability to comply with, and the costs of compliance with, anti-bribery laws such as the Foreign Corrupt Practices Act
and similar local anti-bribery laws;

our ability to compete with owners and operators of wireless towers that have been in the international market for a longer
period of time than we have;

uncertainties regarding legal or judicial systems, including inconsistencies between and within laws, regulations and
decrees, and judicial application thereof, and delays in the judicial process;

health or similar issues, such as a pandemic or epidemic;

difficulty in recruiting and retaining trained personnel; and

language and cultural differences.

12

A slowdown in demand for wireless communications services or for tower space could materially and adversely affect our future
growth and revenues, and we cannot control that demand.

Additional revenue growth on our towers other than through contractual escalators comes directly from additional investment
by our wireless service provider customers in their networks. If consumers significantly reduce their minutes of use or data usage, or
fail to widely adopt and use wireless data applications, our wireless service provider customers could experience a decrease in demand
for their services. Regardless of consumer demand, each wireless service provider customer must have substantial capital resources
and capabilities to build out their wireless networks, including licenses for spectrum. In addition, our wireless service customers have
engaged in increased use of network sharing, roaming or resale arrangements. As a result of all of the above, wireless service
providers may scale back their business plans or otherwise reduce their spending, which could materially and adversely affect demand
for our tower space and our wireless communications services business, which could have a material adverse effect on our business,
results of operations and financial condition.

We may not be able to fully recognize the anticipated benefits of towers that we acquire.

A key element of our growth strategy is to increase our tower portfolio through acquisitions.  We rely on our due diligence of
the towers and the representations and financial records of the sellers and other third parties to establish the anticipated revenues and
expenses and whether the acquired towers will meet our internal guidelines for current and future potential returns. In addition, we
may not always have the ability to analyze and verify all information regarding title, access and other issues regarding the land
underlying acquired towers.  This is particularly true in our international acquisitions of towers from wireless service providers. To the
extent that these towers were acquired in individually material transactions, we may be required to place enhanced reliance on the
financial and operational representations and warranties of the sellers. If (i) these records are not complete or accurate, (ii) we do not
have complete access to, or use of, the land underlying the acquired towers or (iii) the towers do not achieve the financial results
anticipated, it could adversely affect our revenues and results of operations.

In addition, acquisitions which would be material in the aggregate may exacerbate the risks inherent with our growth strategy,

such as (i) an adverse impact on our overall profitability if the acquired towers do not achieve the projected financial results, (ii)
unanticipated costs associated with the acquisitions that may impact our results of operations for a period, (iii) increased demands on
our cash resources that may, among other things, impact our ability to explore other opportunities, (iv) undisclosed and assumed
liabilities that we may be unable to recover, (v) increased vulnerability to general economic conditions, (vi) an adverse impact on our
existing customer relationships, (vii) additional expenses and exposure to new regulatory, political and economic risks if such
acquisitions were in new jurisdictions and (viii) diversion of managerial attention.

The process of integrating any acquired towers into our operations may result in unforeseen operating difficulties and large
expenditures and may absorb significant management attention that would otherwise be available for the ongoing development of our
business. It may also result in the loss of key customers and/or personnel and expose us to unanticipated liabilities. These risks may be
exacerbated in those circumstances in which we acquire a material number of towers. Further, we may not be able to retain the key
employees that may be necessary to operate the business we acquire, and we may not be able to timely attract new skilled employees
and management to replace them. There can be no assurance that we will be successful in integrating acquisitions into our existing
business. This is particularly true in our international acquisitions of towers from wireless service providers.

Delays or changes in the deployment or adoption of new technologies or slowing consumer adoption rates may have a material
adverse effect on our growth rate.

There can be no assurances that 3G, 4G, including long-term evolution (“LTE”), advanced wireless service in the 1695-1710

MHz, 1755-1780 MHz, and 2155-2180 MHz bands (the “AWS-3” bands), or other new wireless technologies such as 5G will be
deployed or adopted as rapidly as projected or that these new technologies will be implemented in the manner anticipated. The
deployment of 3G in the United States experienced delays from the original projected timelines of the wireless and broadcast
industries, and continued deployment of 4G could experience delays. Additionally, the demand by consumers and the adoption rate of
consumers for these new technologies once deployed may be lower or slower than anticipated, particularly in certain of our
international markets. These factors could have a material adverse effect on our growth rate since growth opportunities and demand
for our tower space as a result of such new technologies may not be realized at the times or to the extent anticipated.

Increasing competition in the tower industry may create pricing pressures that may materially and adversely affect us.

Our industry is highly competitive, and our wireless service provider customers sometimes have alternatives for leasing antenna
space. Some of our competitors, such as (1) U.S. and international wireless carriers that allow co-location on their towers and (2) large
independent tower companies, have been, and based on recent consolidations continue to be, substantially larger and have greater

13

financial resources than we do. This could provide them with advantages with respect to establishing favorable leasing terms with
wireless service providers or in their ability to acquire available towers.

In the site leasing business, we compete with:

•

•

•

wireless service providers that own and operate their own towers and lease, or may in the future decide to lease, antenna
space to other providers;

national and regional tower companies; and

alternative facilities such as rooftops, outdoor and indoor DAS networks, billboards and electric transmission towers.

We believe that tower location and capacity, quality of service, density within a geographic market and, to a lesser extent, price

historically have been and will continue to be the most significant competitive factors affecting the site leasing business. However,
competitive pricing pressures for tenants on towers from these competitors could materially and adversely affect our lease rates. In
addition, we may not be able to renew existing customer leases or enter into new customer leases, resulting in a material adverse
impact on our results of operations and growth rate. Increasing competition could also make the acquisition of high quality tower
assets more costly, or limit the acquisition opportunities altogether. Any of these factors could materially and adversely affect our
business, results of operations or financial condition.

The site development segment of our industry is also extremely competitive. There are numerous large and small companies that

offer one or more of the services offered by our site development business. As a result of this competition, margins in this segment
may come under pressure. Many of our competitors have lower overhead expenses and therefore may be able to provide services at
prices that we consider unprofitable. If margins in this segment were to decrease, our consolidated revenues and our site development
segment operating profit could be adversely affected.

The documents governing our indebtedness contain restrictive covenants that could adversely affect our business by limiting our
flexibility.

The indentures governing the 2014 Senior Notes and the 2016 Senior Notes, the Senior Credit Agreement, and the mortgage
loan underlying the Tower Securities contain restrictive covenants imposing significant operational and financial restrictions on us,
including restrictions that may limit our ability to engage in acts that may be in our long-term best interests. Among other things, the
covenants under each instrument limit our ability to:

•

•

•

•

•

merge, consolidate or sell assets;

make restricted payments, including pay dividends or make other distributions;

enter into transactions with affiliates;

enter into sale and leaseback transactions; and

issue guarantees of indebtedness.

We are required to maintain certain financial ratios under the Senior Credit Agreement. The Senior Credit Agreement, as

amended, requires SBA Senior Finance II to maintain specific financial ratios, including (1) a ratio of Consolidated Total Debt to
Annualized Borrower EBITDA not to exceed 6.5 times for any fiscal quarter, (2) a ratio of Consolidated Total Debt and Net Hedge
Exposure (calculated in accordance with the Senior Credit Agreement) to Annualized Borrower EBITDA for the most recently ended
fiscal quarter not to exceed 6.5 times for 30 consecutive days and (3) a ratio of Annualized Borrower EBITDA to Annualized Cash
Interest Expense (calculated in accordance with the Senior Credit Agreement) of not less than 2.0 times for any fiscal quarter.

Additionally, the mortgage loan relating to our Tower Securities contains financial covenants that require that the borrowers

maintain, on a consolidated basis, a minimum debt service coverage ratio. To the extent that the debt service coverage ratio, as of the
end of any calendar quarter, falls to 1.30 times or lower, then all cash flow in excess of amounts required to make debt service
payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other payments required
under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of being released to the

14

borrowers. The funds in the reserve account will not be released to the borrowers unless the debt service coverage ratio exceeds 1.30
times for two consecutive calendar quarters. If the debt service coverage ratio falls below 1.15 times as of the end of any calendar
quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be applied to prepay the
mortgage loan until such time that the debt service coverage ratio exceeds 1.15 times for a calendar quarter.

These covenants could place us at a disadvantage compared to some of our competitors which may have fewer restrictive

covenants and may not be required to operate under these restrictions. Further, these covenants could have an adverse effect on our
business by limiting our ability to take advantage of financing, new tower development, merger and acquisitions or other
opportunities. If we fail to comply with these covenants, it could result in an event of default under our debt instruments. If any default
occurs, all amounts outstanding under our outstanding notes and the Senior Credit Agreement may become immediately due and
payable.

Our variable rate indebtedness and refinancing obligations subject us to interest rate risk, which could cause our debt service
obligations to increase significantly.

Fluctuations in market interest rates may increase interest expense relating to our floating rate indebtedness, which we expect to

incur under the Revolving Credit Facility and Term Loans or upon refinancing our fixed rate debt. As a result, we are exposed to
interest rate risk. If interest rates were to increase, our debt service obligations on the variable rate indebtedness would increase even
though the amount borrowed remained the same, and our net income and cash flows, including cash available for servicing our
indebtedness, will correspondingly decrease. There is no guarantee that any future refinancing of our indebtedness will have fixed
interest rates or that interest rates on such indebtedness will be equal to or lower than the rates on our current indebtedness. In the
future, we may enter into interest rate swaps that involve the exchange of floating for fixed rate interest payments in order to reduce
interest rate volatility. However, we may not maintain interest rate swaps with respect to all of our variable rate indebtedness, and any
swaps we enter into may not fully mitigate our interest rate risk. We currently have no interest rate swaps.

Our dependence on our subsidiaries for cash flow may negatively affect our business.

We are a holding company with no business operations of our own. Our only significant assets are, and are expected to be, the

outstanding capital stock and membership interests of our subsidiaries. We conduct, and expect to continue conducting, all of our
business operations through our subsidiaries. Accordingly, our ability to pay our obligations is dependent upon dividends and other
distributions from our subsidiaries to us. Most of our indebtedness is owed directly by our subsidiaries, including the mortgage loan
underlying the Tower Securities, the Term Loans and any amounts that we may borrow under the Revolving Credit Facility.
Consequently, the first use of any cash flow from operations generated by such subsidiaries will be payments of interest and principal,
if any, under their respective indebtedness. Other than the cash required to repay amounts due under our 2014 Senior Notes and 2016
Senior Notes and funds to be utilized for stock repurchases, we currently expect that substantially all the earnings and cash flow of our
subsidiaries will be retained and used by them in their operations, including servicing their respective debt obligations. The ability of
our operating subsidiaries to pay dividends or transfer assets to us is restricted by applicable state law and contractual restrictions,
including the terms of their outstanding debt instruments.

Our quarterly operating results for our site development services fluctuate and therefore we may not be able to adjust our cost
structure on a timely basis with regard to such fluctuations.

The demand for our site development services fluctuates from quarter to quarter and should not be considered indicative of

long-term results. Numerous factors cause these fluctuations, including:

•

•

•

•

•

•

the timing and amount of our customers’ capital expenditures;

the size and scope of our projects;

the business practices of customers, such as deferring commitments on new projects until after the end of the calendar
year or the customers’ fiscal year;

delays relating to a project or tenant installation of equipment;

seasonal factors, such as weather, holidays and vacation days and total business days in a quarter;

the use of third party providers by our customers;

15

•

•

the rate and volume of wireless service providers’ network development; and

general economic conditions.

Although the demand for our site development services fluctuates, we incur significant fixed costs, such as maintaining a staff
and office space, in anticipation of future contracts. In addition, the timing of revenues is difficult to forecast because our sales cycle
may be relatively long. Therefore, we may not be able to adjust our cost structure on a timely basis to respond to the fluctuations in
demand for our site development services.

We have not traditionally been profitable and may incur losses in the future.

In 2016, we were profitable; however, in 2015 and 2014, we were not profitable. The following chart shows the net income

(losses) we incurred for the periods indicated:

Net income (loss)

$

76,238

$

(175,656)

(24,295)

During 2015 and 2014, our losses were principally due to depreciation, amortization, and accretion expenses, interest expense

(including non-cash interest expense and amortization of deferred financing fees), and losses from the extinguishment of debt. In
addition, in 2015, our loss included remeasurement losses related to a foreign currency denominated intercompany loan.

The loss of the services of certain of our key personnel or a significant number of our employees may negatively affect our
business.

Our success depends to a significant extent upon performance and active participation of our key personnel. We cannot

guarantee that we will be successful in retaining the services of these key personnel. We have employment agreements with Jeffrey A.
Stoops, our President and Chief Executive Officer, Kurt L. Bagwell, our Executive Vice President and President—International,
Thomas P. Hunt, our Executive Vice President, Chief Administrative Officer and General Counsel, and Brendan T. Cavanagh, our
Executive Vice President and Chief Financial Officer. We do not have employment agreements with any of our other key personnel. If
we were to lose any key personnel, we may not be able to find an appropriate replacement on a timely basis and our results of
operations could be negatively affected. Further, the loss of a significant number of employees or our inability to hire a sufficient
number of qualified employees could have a material adverse effect on our business.

Our business is subject to government regulations and changes in current or future regulations could harm our business.

We are subject to federal, state and local regulation of our business, both in the U.S. and internationally. In the U.S., both the
FAA and the FCC regulate the construction, modification, and maintenance of towers and structures that support antennas used for
wireless communications and radio and television broadcasts. In addition, the FCC separately licenses and regulates wireless
communications equipment and television and radio stations operating from such towers. FAA and FCC regulations govern
construction, lighting, painting, and marking of towers and may, depending on the characteristics of the tower, require registration of
the tower. Certain proposals to construct new towers or to modify existing towers are reviewed by the FAA to ensure that the tower
will not present a hazard to air navigation.

Tower owners may have an obligation to mark or paint such towers or install lighting to conform to FAA and FCC regulations

and to maintain such marking, painting and lighting. Tower owners may also bear the responsibility of notifying the FAA of any
lighting outages. Certain proposals to operate wireless communications and radio or television stations from towers are also reviewed
by the FCC to ensure compliance with environmental impact requirements established in federal statutes, including NEPA, NHPA and
ESA. Failure to comply with existing or future applicable requirements may lead to civil penalties or other liabilities and may subject
us to significant indemnification liability to our customers against any such failure to comply. In addition, new regulations may
impose additional costly burdens on us, which may affect our revenues and cause delays in our growth.

Local regulations, including municipal or local ordinances, zoning restrictions and restrictive covenants imposed by community

developers, vary greatly, but typically require tower owners to obtain approval from local officials or community standards
organizations prior to tower construction or modification. Local regulations can delay, prevent, or increase the cost of new
construction, co-locations, or site upgrades, thereby limiting our ability to respond to customer demand. In addition, new regulations

16

may be adopted that increase delays or result in additional costs to us. Furthermore, with respect to our international new builds, our
tower construction may be delayed or halted as a result of local zoning restrictions, inconsistencies between laws or other barriers to
construction in international markets. These factors could have a material adverse effect on our future growth and operations.

Security breaches and other disruptions could compromise our information, which would cause our business and reputation to
suffer.

A part of our day-to-day operations, we rely on information technology and other computer resources and infrastructure to carry

out important business activities and to maintain our business records. Our computer systems could fail on their own accord and are
subject to interruption or damage from power outages, computer and telecommunications failures, computer viruses, security breaches
(including through cyber-attack and data theft), errors, catastrophic events such as natural disasters and other events beyond our
control. If our computer systems and our backup systems are compromised, degraded, damaged, or breached, or otherwise cease to
function properly, we could suffer interruptions in our operations or unintentionally allow misappropriation of proprietary or
confidential information (including information about our tenants or landlords). This could damage our reputation and disrupt our
operations and the services we provide to customers, which could adversely affect our business and operating results.

Our towers are subject to damage from natural disasters and other unforeseen events.

Our towers are subject to risks associated with natural disasters such as tornadoes, hurricanes and earthquakes or may collapse
for any number of reasons, including structural deficiencies. We maintain insurance to cover the estimated cost of replacing damaged
towers, but these insurance policies are subject to loss limits and deductibles. We also maintain third party liability insurance, subject
to loss limits and deductibles, to protect us in the event of an accident involving a tower. A tower accident for which we are uninsured
or underinsured, or damage to a significant number of our towers, could require us to incur significant expenditures and may have a
material adverse effect on our operations or financial condition and may harm our reputation.

To the extent that we are not able to meet our contractual obligations to our customers, due to a natural disaster or other
catastrophic circumstances, our customers may not be obligated or willing to pay their lease expenses; however, we may be required
to continue paying our fixed expenses related to the affected tower, including ground lease expenses. If we are unable to meet our
contractual obligations to our customers for a material portion of our towers, our operations could be materially and adversely
affected.

We could have liability under environmental laws that could have a material adverse effect on our business, financial condition
and results of operations.

Our operations, like those of other companies engaged in similar businesses, are subject to the requirements of various federal,

state, local and foreign environmental and occupational safety and health laws and regulations, including those relating to the
management, use, storage, disposal, emission and remediation of, and exposure to, hazardous and non-hazardous substances,
materials, and wastes. As owner, lessee, or operator of numerous tower structures, we may be liable for substantial costs of
remediating soil and groundwater contaminated by hazardous materials without regard to whether we, as the owner, lessee, or
operator, knew of or were responsible for the contamination. We may be subject to potentially significant fines or penalties if we fail
to comply with any of these requirements. The current cost of complying with these laws is not material to our financial condition or
results of operations. However, the requirements of these laws and regulations are complex, change frequently, and could become
more stringent in the future. It is possible that these requirements will change or that liabilities will arise in the future in a manner that
could have a material adverse effect on our business, financial condition and results of operations.

We could suffer adverse tax and other financial consequences if taxing authorities do not agree with our tax positions.

We are periodically subject to a number of tax examinations by taxing authorities in the states and countries where we do

business. We also have significant net operating losses (“NOLs”) in U.S. federal and state taxing jurisdictions. Generally, for U.S.
federal and state tax purposes, NOLs can be carried forward and used for up to twenty years, and all of our tax years will remain
subject to examination until three years after our NOLs are used or expire. We expect that we will continue to be subject to tax
examinations in the future. In addition, U.S. federal, state and local, as well as international, tax laws and regulations are extremely
complex and subject to varying interpretations. If our tax benefits, including from our use of NOLs or other tax attributes, are
challenged successfully by a taxing authority, we may be required to pay additional taxes or penalties, or make additional
distributions, which could have a material adverse effect on our business, results of operations and financial condition.

17

Our issuance of equity securities and other associated transactions may trigger a future ownership change which may negatively
impact our ability to utilize NOLs in the future.

The issuance of equity securities and other associated transactions may increase the chance that we will have a future ownership
change under Section 382 of the Internal Revenue Code of 1986. We may also have a future ownership change, outside of our control,
caused by future equity transactions by our current shareholders. Depending on our market value at the time of such future ownership
change, an ownership change under Section 382 could negatively impact our ability to utilize our NOLs and could result in us having
to make additional cash distributions.

Our costs could increase and our revenues could decrease due to perceived health risks from RF energy.

The U.S. government imposes requirements and other guidelines relating to exposure to RF energy. Exposure to high levels of

RF energy can cause negative health effects. The potential connection between exposure to low levels of RF energy and certain
negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent
years. According to the FCC, the results of these studies to date have been inconclusive. However, public perception of possible health
risks associated with cellular and other wireless communications media could slow the growth of wireless companies, which could in
turn slow our growth. In particular, negative public perception of, and regulations regarding, health risks could cause a decrease in the
demand for wireless communications services. Moreover, if a connection between exposure to low levels of RF energy and possible
negative health effects, including cancer, were demonstrated, we could be subject to numerous claims. Our current policies provide no
coverage for claims based on RF energy exposure. If we were subject to claims relating to exposure to RF energy, even if such claims
were not ultimately found to have merit, our financial condition could be materially and adversely affected.

Risks Related to Our Status as a REIT

Complying with the REIT requirements may cause us to liquidate assets or hinder our ability to pursue otherwise attractive asset
acquisition opportunities.

To qualify as a REIT for federal income tax purposes, we must continually satisfy tests concerning, among other things, the

nature and diversification of our assets, the sources of our income and the amounts we distribute to our shareholders. For example, to
qualify as a REIT, we must ensure that, at the end of each calendar quarter, at least 75% of the value of our assets consists of cash,
cash items, government securities and “real estate assets” (as defined in the Code), including towers and certain mortgage loans and
securities. The remainder of our investments (other than government securities, qualified real estate assets and securities issued by a
taxable REIT subsidiary (“TRS”) generally cannot include more than 10% of the outstanding voting securities of any one issuer or
more than 10% of the total value of the outstanding securities of any one issuer. In addition, in general, no more than 5% of the value
of our total assets (other than government securities, qualified real estate assets and securities issued by a TRS) can consist of the
securities of any one issuer, and no more than 25% (for taxable years beginning on or before December 31, 2017) or 20% (for taxable
years beginning after December 31, 2017) of the value of our total assets can be represented by securities of one or more TRSs. If we
fail to comply with these requirements 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 and suffering adverse tax
consequences. As a result, we may be required to liquidate assets.

In addition to the asset tests set forth above, to qualify and be subject to tax as a REIT, we will generally be required to

distribute 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) each year to our shareholders. Our determination as to the timing or amount
of future dividends will be based on a number of factors, including investment opportunities around our core business and the
availability of our existing NOLs. To the extent that we satisfy the 90% distribution requirement, but distribute less than 100% of our
REIT taxable income (after the application of available NOLs, if any), we will be subject to U.S. 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 shareholders for a calendar year is less than a minimum amount specified under the Code. These distribution requirements could
hinder our ability to pursue otherwise attractive asset acquisition opportunities. Furthermore, our ability to compete for acquisition
opportunities in domestic and international markets may be adversely affected if we need, or require, the target company to comply
with certain REIT requirements. These actions could have the effect of reducing our income, amounts available for distribution to our
shareholders and amounts available for making payments on our indebtedness.

18

Qualifying as a REIT involves highly technical and complex provisions of the Code. If we fail to qualify as a REIT or fail to
remain qualified as a REIT, to the extent we have REIT taxable income and have utilized our NOLs, we will be subject to U.S.
federal income tax as a regular corporation and could face a substantial tax liability, which would reduce the amount of cash
available for distribution to our shareholders.

Qualification as a REIT involves the application of highly technical and complex Code provisions for which only limited

judicial and administrative authorities exist. Even a technical or inadvertent violation could jeopardize our REIT qualification. Our
qualification as a REIT will depend on our satisfaction of certain asset, income, organizational, distribution, shareholder ownership
and other requirements on a continuing basis.

Our Board of Directors has authorized us to take all necessary steps for SBAC to be subject to tax as a REIT for U.S. federal

income tax purposes, commencing with our taxable year ending December 31, 2016. We received an opinion of our special REIT tax
counsel with respect to our qualification as a REIT. Investors should be aware, however, that opinions of counsel are not binding on
the IRS or any court. The opinion represents only the view of such counsel based on its review and analysis of existing law and on
certain representations as to factual matters and covenants made by us, including representations relating to the values of our assets
and the sources of our income. The opinion is expressed as of the date issued. Our qualification as a REIT will depend on our
satisfaction of certain asset, income, organizational, distribution, shareholder ownership and other requirements on a continuing
basis. Our ability to satisfy the asset tests depends upon our analysis of the characterization and fair market values of our assets, some
of which are not susceptible to a precise determination, and for which we will not obtain independent appraisals.

If we fail to qualify as a REIT in any taxable year, to the extent we have REIT taxable income and have utilized our NOLs, we

would be subject to U.S. federal income tax, including any applicable alternative minimum tax, on our taxable income at regular
corporate rates, and dividends paid to our shareholders would not be deductible by us in computing our taxable income. Any resulting
corporate tax liability could be substantial and would reduce the amount of cash available for distribution to our shareholders, which
in turn could have an adverse impact on the value of our common stock. Unless we were entitled to relief under certain provisions of
the Code, we also would be disqualified from re-electing to be taxed as a REIT for the four taxable years following the year in which
we failed to qualify as a REIT. If we fail to qualify for taxation as a REIT, we may need to borrow additional funds or liquidate assets
to pay any additional tax liability. Accordingly, funds available for investment and making payments on our indebtedness would be
reduced.

We may be required to borrow funds, sell assets, or raise equity to satisfy our REIT distribution requirements.

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 may need to borrow
funds, sell assets or raise equity, even if the then-prevailing market conditions are not favorable for these borrowings, sales or
offerings, to enable us to satisfy the REIT distribution requirement and to avoid U.S. federal corporate income tax and the 4% excise
tax in a particular year. These alternatives could increase our costs and our leverage, decrease our Adjusted Funds From Operations
per share or require us to distribute amounts that would otherwise be invested in future acquisitions or stock repurchases.

Thus, compliance with the REIT requirements may hinder our ability to grow, which could adversely affect the value of our

common stock. Furthermore, compliance with the REIT distribution requirements may increase the financing we need to fund capital
expenditures, future growth, or expansion initiatives, which would increase our total leverage.

Covenants specified in our current and future debt instruments may limit our ability to make required REIT distributions.

The Senior Credit Agreement, the mortgage loan agreement related to our securitization transactions and the indentures
governing our 2014 Senior Notes and 2016 Senior Notes contain certain covenants that could limit our ability to make distributions to
our shareholders. Under the Senior Credit Agreement, our subsidiaries may make distributions to us to satisfy our REIT distribution
requirements and additional amounts to distribute up to 100% of our REIT taxable income, so long as SBA Senior Finance II’s ratio of
Consolidated Total Debt to Annualized Borrower EBITDA does not exceed 6.5 times for any fiscal quarter. In addition, under the
mortgage loan agreement related to our securitization transactions, or Securitization, a failure to comply with the Debt Service
Coverage Ratio in that agreement could prevent our borrower subsidiaries from distributing any excess cash from the operation of
their towers to us. Finally, while the indentures governing the 2014 Senior Notes and the 2016 Senior Notes permit us to make
distributions to our shareholders to the extent such distributions are necessary to maintain our status as a REIT or to avoid entity level
taxation, this authority is subject to the conditions that no default or event of default exists or would result therefrom and that the
obligations under the 2014 Senior Notes or the 2016 Senior Notes, as applicable, have not otherwise been accelerated.

If these limits prevent us from satisfying our REIT distribution requirements, we could fail to qualify for taxation as a REIT. If

these limits do not jeopardize our qualification for taxation as a REIT but do nevertheless prevent us from distributing 100% of our

19

REIT taxable income, we will be subject to U.S. federal corporate income tax, and potentially the nondeductible 4% excise tax, on the
retained amounts.

Our payment of cash distributions in the future is not guaranteed and the amount of any future cash distributions may fluctuate,
which could adversely affect the value of our Class A common stock.

REITs are required to distribute annually at least 90% of their REIT taxable income (determined before the deduction for

dividends paid and excluding any net capital gain). As of December 31, 2016, $1.1 billion of the federal NOLs are attributes of the
REIT. We may use these NOLs to offset our REIT taxable income, and thus any required distributions to shareholders may be reduced
or eliminated until such time as the NOLs have been fully utilized. The Internal Revenue Code places limitations upon the future
availability of NOLs based upon changes in our equity. If these occur, our ability to offset future income with existing NOLs may be
limited. We currently expect that we will utilize available NOLs to reduce all or a portion of our REIT taxable income and therefore
we may not initially make any distributions, which may adversely affect the market value of our Class A common stock.

The amount of future distributions will be determined, from time to time, by the Board of Directors to balance our goal of

increasing long-term shareholder value and retaining sufficient cash to implement our current capital allocation policy, which
prioritizes investment in quality assets that meet our return criteria, and then stock repurchases, when we believe our stock price is
below its intrinsic value. The actual timing and amount of distributions will be as determined and declared by the Board of Directors
and will depend on, among other factors, our NOLs, our financial condition, earnings, debt covenants and other possible uses of such
funds. Consequently, our future distribution levels may fluctuate.

Certain of our business activities may be subject to corporate level income tax and foreign taxes, which would reduce our cash
flows, and would have potential deferred and contingent tax liabilities.

We may be subject to certain federal, state, local and foreign taxes on our income and assets, including alternative minimum
taxes, taxes on any undistributed income and state, local or foreign income, franchise, property and transfer taxes. In addition, we
could, in certain circumstances, be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize
one or more relief provisions under the Code to maintain qualification for taxation as a REIT. In addition, we may incur a 100%
excise tax on transactions with a TRS if they are not conducted on an arm’s length basis. Any of these taxes would decrease our
earnings and our available cash.

Our TRS assets and operations also will continue to be subject, as applicable, to federal and state corporate income taxes and to
foreign taxes in the jurisdictions in which those assets and operations are located. Any of these taxes would decrease our earnings and
our available cash. We will also be subject to a federal corporate level tax at the highest regular corporate rate (currently 35%) on the
gain recognized from a sale of assets occurring during our first five years as a REIT, up to the amount of the built-in gain that existed
on January 1, 2016, which is based on the fair market value of those assets in excess of our tax basis in those assets as of January 1,
2016. Gain from a sale of an asset occurring after the specified period ends will not be subject to this corporate level tax. We currently
do not expect to sell any asset if the sale would result in the imposition of a material tax liability. We cannot, however, assure you that
we will not change our plans in this regard.

Our use of TRSs may cause us to fail to qualify as a REIT.

The net income of our TRSs is not required to be distributed to us, and such undistributed TRS income is generally not subject

to our REIT distribution requirements. However, if the accumulation of cash or reinvestment of significant earnings in our TRSs
causes the fair market value of our securities in those entities, taken together with other non-qualifying assets, to represent more than
25% of the fair market value of our assets, or causes the fair market value of our TRS securities alone to represent more than 25% (for
taxable years beginning on or before December 31, 2017) or 20% (for taxable years beginning after December 31, 2017) of the value
of our total assets, in each case, as determined for REIT asset testing purposes, we would, absent timely responsive action, fail to
qualify as a REIT.

Legislative or other actions affecting REITs could have a negative effect on us.

The rules dealing with U.S. federal income taxation are constantly under review by persons involved in the legislative process

and by the IRS and the Treasury. Changes to the tax laws or interpretations thereof, with or without retroactive application, could
materially and adversely affect our investors or us. We cannot predict how changes in the tax laws might affect our investors or
us. New legislation, U.S. Treasury Regulations, administrative interpretations or court decisions could significantly and negatively
affect our ability to qualify as a REIT or the U.S. federal income tax consequences to our investors and us of such qualification.

20

Our Board’s ability to revoke our REIT qualification, without shareholder approval , may cause adverse consequences to our
shareholders.

Our articles of incorporation provide that our Board of Directors may revoke or otherwise terminate our REIT election, without
the approval of our shareholders, if it determines that it is no longer in our best interests to continue to qualify as a REIT. If we cease
to be a REIT, we will not be allowed a deduction for dividends paid to shareholders, if any, in computing our taxable income, and to
the extent we have taxable income and have utilized our NOLs, we will be subject to U.S. federal income tax at regular corporate rates
and state and local taxes, which may have adverse consequences on our total return to our shareholders.

We do not have any experience operating as a REIT, which may adversely affect our financial condition, results of operations,
cash flow, per share trading price of our common stock and ability to satisfy debt service obligations.

While we believe that we are currently operating in a manner that complies with the REIT rules, we have not actually operated

as a REIT previously. Our pre-REIT operating experience may not be sufficient to enable us to operate successfully as a REIT. In
addition, we will be required to implement substantial control systems and procedures in order to maintain our status as a REIT. As a
result, we may incur additional legal, accounting and other expenses that we have not previously incurred, which could be significant,
and our management and other personnel may need to devote additional time to comply with these rules and regulations and controls
required for continued compliance with the Code. These costs and time commitments could be substantially more than we currently
expect. Therefore, our historical combined consolidated financial statements may not be indicative of our future costs and
performance as a REIT. If our performance is adversely affected, it could affect our financial condition, results of operations, cash
flow and ability to satisfy our debt service obligations.

The historical market price of our Class A common stock may not be indicative of the market price of our Class A common stock
following the REIT conversion.

The historical market price of our Class A common stock may not be indicative of how the market values our Class A common
stock following our REIT conversion because of the change in our organization from a taxable C corporation to a REIT. Although we
do not currently anticipate commencing distributions until a future date, the stock price of REIT securities have historically been
affected by changes in market interest rates as investors evaluate the annual yield from distributions on the entity’s common stock as
compared to yields on other financial instruments. In addition, the market price of our Class A common stock may be affected by the
economic and market perception of REIT securities as well as general market conditions.

As a REIT, we are no longer eligible to be included in the NASDAQ 100 Index. Therefore, those index funds that invest in the
equity of NASDAQ 100 companies will be required to sell our shares and not purchase them in the future, which could have an
adverse effect on the volatility and market price of our Class A common stock.

One of the eligibility criteria for the NASDAQ 100 Index is that the company is not a financial company.  As a REIT, we are

considered a financial company, even though our business model has not changed in connection with the REIT conversion; and
therefore, we are no longer eligible to be included in the NASDAQ 100 Index. As a result, those index funds that invest in NASDAQ
100 companies will be required to sell shares of our Class A common stock and not purchase them in the future.  In addition, other
non-index funds that use inclusion on the NASDAQ 100 Index as a component of their investment criteria may be required to sell and
no longer invest in our Class A common stock.  We do not know how many shares of our Class A common stock are held by these
index and non-index funds.  The sales of significant amounts of shares of our Class A common stock or the perception in the market
that this will occur could have an adverse effect on the volatility and market price of our Class A common stock.

Dividends payable by REITs do not qualify for the reduced tax rates available for some dividends.

The maximum U.S. federal income tax rate applicable to income from “qualified dividends” payable to U.S. shareholders that
are individuals, trusts and estates is currently 20%. Dividends payable by REITs, however, generally are not eligible for the reduced
rates applicable to qualified dividends. Although these rules do not adversely affect the taxation of REITs, the more favorable rates
applicable to regular corporate qualified dividends could cause investors who are individuals, trusts and estates to perceive
investments in REITs to be relatively less attractive than investments in the stocks of non-REIT corporations that pay dividends,
which could adversely affect the value of the stock of REITs, including our common stock.

21

Risks Related to Ownership of our Class A Common Stock

The REIT-related ownership and transfer restrictions may restrict or prevent you from engaging in certain transfers of our
common stock.

In order for us to satisfy the requirements for REIT qualification, no more than 50% in value of all classes or series of our
outstanding shares of stock may be owned, beneficially or constructively, by five or fewer individuals (as defined in the Code to
include certain entities) at any time during the last half of each taxable year (other than the first year for which an election to be
subject to tax as a REIT has been made). In addition, 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 (other than the first year for
which an election to be taxed as a REIT has been made). Our articles of incorporation contain REIT-related ownership and transfer
restrictions that generally restrict shareholders from owning more than 9.8%, by value or number of shares, whichever is more
restrictive, of our outstanding shares of Class A common stock, or 9.8% in aggregate value of the outstanding shares of all classes and
series of our capital stock. Under applicable constructive ownership rules, any shares of stock owned by certain affiliated owners
generally would be added together for purposes of the ownership limits. These ownership and transfer restrictions could have the
effect of delaying, deferring or preventing a transaction or a change in control that might involve a premium price for our capital stock
or otherwise be in the best interest of our shareholders.

Future sales of our Class A common stock in the public market or the issuance of other equity may cause dilution or adversely
affect the market price of our Class A common stock and our ability to raise funds in new equity or equity-related offerings.

Sales of a substantial number of shares of our Class A common stock or other equity-related securities in the public market,

including sales by any selling shareholder, could depress the market price of our Class A common stock and impair our ability to raise
capital through the sale of additional equity securities.

Our articles of incorporation, our bylaws and Florida law provide for anti-takeover provisions that could make it more difficult for
a third party to acquire us.

Provisions of our articles of incorporation, our bylaws and Florida law could make it more difficult for a third party to acquire

us, even if doing so would be beneficial to our shareholders. These provisions, alone or in combination with each other, may
discourage transactions involving actual or potential changes of control, including transactions that otherwise could involve payment
of a premium over prevailing market prices to holders of our Class A common stock, or could limit the ability of our shareholders to
approve transactions that they may deem to be in their best interests.

ITEM 2. PROPERTIES

We own our headquarters in Boca Raton, Florida where we currently have approximately 160,000 square feet of office space.
We have entered into long-term leases for international and regional locations convenient for the management and operation of our
site leasing activities, and in certain site development office locations where we expect our activities to be longer-term. We open and
close project offices from time to time in connection with our site development business. We believe our existing facilities are
adequate for our current and planned levels of operations and that additional office space suited for our needs is reasonably available
in the markets within which we operate.

Our interests in towers and the land beneath them are comprised of a variety of fee interests, leasehold interests created by long-
term lease agreements, perpetual easements, easements, licenses, rights-of-way, and other similar interests. As of December 31, 2016,
approximately 72% of our tower structures were located on parcels of land that we own, land subject to perpetual easements, or
parcels of land that have an interest that extends beyond 20 years. The average remaining life under our ground leases, including
renewal options under our control, is 33 years. In rural areas, support for our towers, equipment shelters, and related equipment
requires a tract of land typically up to 10,000 square feet. Less than 2,500 square feet is required for a monopole or self-supporting
tower of the kind typically used in metropolitan areas for wireless communications towers. Ground leases are generally for an initial
term of five years or more with five or more additional automatic renewal periods of five years, for a total of thirty years or more.

Most of our towers have significant capacity available for additional antennas. We measure the available capacity of our

existing facilities to support additional tenants and generate additional lease revenue by assessing several factors, including tower
height, tower type, wind loading, environmental conditions, existing equipment on the tower and zoning and permitting regulations in
effect in the jurisdiction where the tower is located. As of December 31, 2016, we had an average of 1.8 tenants per tower structure.

22

ITEM 3. LEGAL PROCEEDINGS

We are involved in various legal proceedings relating to claims arising in the ordinary course of business. We do not believe that
the ultimate resolution of these matters will have a material adverse effect on our business, financial condition, results of operations or
liquidity.

Dividends

We have never paid a dividend on any class of common stock.  As a REIT, we are required to distribute annually at least 90% of

our REIT taxable income after the utilization of any available NOLs (determined before the deduction for dividends paid and
excluding any net capital gain). As of December 31, 2016, $1.1 billion of the federal NOLs are attributes of the REIT. We may use
these NOLs to offset our REIT taxable income, and thus any required distributions to shareholders may be reduced or eliminated until
such time as our NOLs have been fully utilized. The amount of future distributions will be determined, from time to time, by the board
of directors to balance our goal of increasing long-term shareholder value and retaining sufficient cash to implement our current
capital allocation policy, which prioritizes investment in quality assets that meet our return criteria, and then stock repurchases when
we believe our stock price is below its intrinsic value. The actual amount, timing and frequency of future dividends, will be at the sole
discretion of the board of directors and will be declared based upon various factors, many of which are beyond our control.

On June 4, 2015, our Board of Directors authorized a new stock repurchase plan. This plan authorized us to purchase, from time
to time, up to $1.0 billion of our outstanding Class A common stock through open market repurchases in compliance with Rule
10b-18 under the Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management’s
discretion based on market and business conditions, applicable legal requirements and other factors. Shares purchased were
retired.

On January 12, 2017, our Board of Directors authorized a new stock repurchase plan, replacing the plan authorized on June 4,
2015 which had a remaining authorization of $150.0 million. This plan authorizes us to purchase, from time to time, up to $1.0
billion of our outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 under the
Securities Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on
market and business conditions, applicable legal requirements and other factors. Shares purchased will be retired. The new plan
has no time deadline and will continue until otherwise modified or terminated by our Board of Directors at any time in its sole
discretion.

During the first quarter of 2016, we adopted an accounting standard update on the presentation of debt issuance costs. The new
standard requires debt issuance costs related to a recognized debt liability to be presented in the balance sheet as a direct
deduction from the carrying amount of the debt liability on the consolidated balance sheets. The December 31, 2015, 2014,
2013, and 2012 consolidated balance sheet were retrospectively adjusted to reflect this change.
During the fourth quarter of 2016, we adopted an accounting standard update on the presentation of cash and cash equivalents
in the Statement of Cash Flows. The new standard requires cash and cash equivalent balances to include restricted cash
equivalents. The December 31, 2015, 2014, 2013, and 2012 consolidated statements of cash flows were retrospectively adjusted
to reflect this change.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

The following discussion of our financial condition and results of operations should be read in conjunction with the information

contained in our consolidated financial statements and the notes thereto. The following discussion includes forward-looking
statements that involve certain risks and uncertainties, including, but not limited to, those described in Item 1A. Risk Factors. Our
actual results may differ materially from those discussed below. See “Special Note Regarding Forward-Looking Statements” and
Item 1A. Risk Factors.

We are a leading independent owner and operator of wireless communications infrastructure, including tower structures,
rooftops and other structures that support antennas used for wireless communications, which we collectively refer to as “towers” or
“sites.” Our principal operations are in the United States and its territories. In addition, we own and operate towers in South America,
Central America, and Canada. Our primary business line is our site leasing business, which contributed 98.7% of our total segment
operating profit for the year ended December 31, 2016. In our site leasing business, we (1) lease antenna space to wireless service
providers on towers that we own or operate and (2) manage rooftop and tower sites for property owners under various contractual
arrangements. As of December 31, 2016, we owned 26,197 towers, a substantial portion of which have been built by us or built by
other tower owners or operators who, like us, have built such towers to lease space to multiple wireless service providers. We also
managed or leased approximately 5,500 actual or potential towers, approximately 500 of which were revenue producing as of
December 31, 2016. Our other business line is our site development business, through which we assist wireless service providers in
developing and maintaining their own wireless service networks.

26

REIT Conversion

In October 2016, we announced our intention to take the necessary steps to qualify as a REIT for U.S. federal income tax
purposes.  We refer to this as the REIT conversion.  We believe that our business has been operated in a manner that complies with the
REIT rules since January 1, 2016, and as a result, we intend to make the election to be subject to tax as a REIT commencing with our
taxable year ending December 31, 2016.  Because we believe our business is currently operated in a manner that complies with the
REIT rules, no further reorganization of our operations is necessary to complete the REIT conversion.

As part of the REIT conversion, effective January 13, 2017, we completed the merger with our predecessor that was approved
by our shareholders at a special meeting held on January 12, 2017, and as a result of the merger, we now hold, directly or indirectly
through our subsidiaries, the assets held by our predecessor prior to the merger and conduct the existing businesses of our predecessor
and its subsidiaries.  At the effective time of the merger, all outstanding shares of Class A common stock of our predecessor were
converted into a right to receive an equal number of our shares of Class A common stock.  Although the REIT rules do not require the
completion of this merger, we completed the merger to facilitate our compliance with the REIT rules by ensuring the effective
adoption of certain REIT-related ownership limitations and transfer restrictions related to our capital stock.

A REIT is a corporation that qualifies for special treatment for U.S. federal income tax purposes because, among other things, it

derives most of its income from real estate-based sources and makes a special election under the Code.  We operate as a REIT that
principally invests in, and derives most of its income from the ownership, operation and leasing of, towers.  As a REIT, we generally
will be entitled to a deduction for dividends that we pay and therefore not subject to U.S. federal corporate income tax on that portion
of our net income that we distribute to our shareholders.  However, we will continue to pay U.S. federal income tax on earnings, if
any, from assets and operations held through TRSs. These assets and operations currently consist primarily of our site development
services and our international operations. Our international operations will continue to be subject, as applicable, to foreign taxes in the
jurisdictions in which those operations are located. We may also be subject to a variety of taxes, including payroll taxes and state,
local and foreign income, property and other taxes on our assets and operations.

As a REIT, we will generally be required to distribute 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) each year to our
shareholders.  In addition to the REIT distribution requirements, our determination as to the timing and amount of future dividend
distributions will be based on a number of factors, including investment opportunities around our core business, the availability of our
existing federal NOLs of approximately $1.1 billion as of December 31, 2016 that are attributes of the REIT, our financial condition,
earnings, debt covenants, and other possible uses of such funds.  We may use these NOLs to offset our REIT taxable income, and thus
any required distributions to shareholders may be reduced or eliminated until such time as the NOLs have been fully utilized.  We do
not expect that we will be required to make any distribution of accumulated earnings and profits (commonly referred to as a “purging”
dividend) in connection with our REIT conversion.

Site Leasing Services

Our primary focus is the leasing of antenna space on our multi-tenant towers to a variety of wireless service providers under

long-term lease contracts in the United States, Canada, Central America, and South America. Site leasing revenues are received
primarily from wireless service provider tenants, including AT&T, Sprint, T-Mobile, Verizon Wireless, Oi S.A., Telefonica, Claro,
and TIM. Wireless service providers enter into tenant leases with us, each of which relates to the lease or use of space at an individual
site. In the United States and Canada, our tenant leases are generally for an initial term of five to ten years with five 5-year renewal
periods at the option of the tenant. These tenant leases typically contain specific rent escalators, which average 3-4% per year,
including the renewal option periods. Tenant leases in our Central American and South American markets typically have an initial
term of ten years with multiple five year renewal periods. In Central America, we have similar rent escalators to that of leases in the
United States and Canada while our leases in South America escalate in accordance with a standard cost of living index. Site leases in
South America typically provide for a fixed rental amount and a pass through charge for the underlying ground lease rent.

In our Central American markets and Ecuador, significantly all of our revenue, expenses, and capital expenditures arising from

our new build activities are denominated in U.S. dollars. Specifically, most of our ground leases, tenant leases, and tower-related
expenses are due and paid in U.S. dollars. In our Central American markets, our local currency obligations are principally limited to
(1) permitting and other local fees, (2) utilities, and (3) taxes. In our Brazilian, Canadian, and Chilean operations, significantly all of
our revenue, expenses, and capital expenditures, including tenant leases, ground leases, and other tower-related expenses are
denominated in local currency.

27

Cost of site leasing revenue primarily consists of:

•

•

•

•

•

•

•

Rental payments on ground leases and other underlying property interests;

Straight-line rent adjustment for the difference between rental payments made and the expense recorded as if the
payments had been made evenly throughout the lease term (which may include renewal terms) of the underlying
property interests;

Property taxes;

Site maintenance and monitoring costs (exclusive of employee related costs);

Utilities;

Property insurance; and

Deferred lease origination cost amortization.

Ground leases are generally for an initial term of five years or more with multiple renewal terms of five year periods at our
option and provide for rent escalators which typically average 2-3% annually, or in our South American markets, adjust in accordance
with a standard cost of living index. As of December 31, 2016, approximately 72% of our tower structures were located on parcels of
land that we own, land subject to perpetual easements, or parcels of land in which we have a leasehold interest that extends beyond 20
years. For any given tower, costs are relatively fixed over a monthly or an annual time period. As such, operating costs for owned
towers do not generally increase as a result of adding additional customers to the tower. The amount of direct costs associated with
operating a tower varies from site to site depending on the taxing jurisdiction and the height and age of the tower. The ongoing
maintenance requirements are typically minimal and include replacing lighting systems, painting a tower, or upgrading or repairing an
access road or fencing.

As indicated in the table below, our site leasing business generates substantially all of our total segment operating profit. For
information regarding our operating segments, see Note 18 of our Consolidated Financial Statements included in this annual report.

We believe that over the long-term, site leasing revenues will continue to grow as wireless service providers lease additional
antenna space on our towers due to increasing minutes of network use and data transfer, network expansion and network coverage
requirements. During 2017, we expect organic site leasing revenue in both our domestic and international segments to be consistent
with our growth in 2016. We believe our site leasing business is characterized by stable and long-term recurring revenues, predictable
operating costs and minimal non-discretionary capital expenditures. Due to the relatively young age and mix of our tower portfolio,
we expect future expenditures required to maintain these towers to be minimal. Consequently, we expect to grow our cash flows by
(1) adding tenants to our towers at minimal incremental costs by using existing tower capacity or requiring wireless service providers
to bear all or a portion of the cost of tower modifications and (2) executing monetary amendments as wireless service providers add or
upgrade their equipment. Furthermore, because our towers are strategically positioned and our customers typically do not relocate, we
have historically experienced low tenant lease terminations as a percentage of revenue other than in connection with customer
consolidation or cessations of a specific technology (e.g. iDEN).

Site Development Services

Our site development business, which is conducted in the United States only, is complementary to our site leasing business and

provides us the ability to keep in close contact with the wireless service providers who generate substantially all of our site leasing
revenue and to capture ancillary revenues that are generated by our site leasing activities, such as antenna and equipment installation
at our tower locations. Site development services revenues are earned primarily from providing a full range of end to end services to

28

wireless service providers or companies providing development or project management services to wireless service providers. Our
services include: (1) network pre-design; (2) site audits; (3) identification of potential locations for towers and antennas on existing
infrastructure; (4) support in leasing of the location; (5) assistance in obtaining zoning approvals and permits; (6) tower and related
site construction; (7) antenna installation; and (8) radio equipment installation, commissioning, and maintenance. We provide site
development services at our towers and at towers owned by others on a local basis, through regional, market, and project offices. The
market offices are responsible for all site development operations.

For information regarding our operating segments, see Note 18 of our Consolidated Financial Statements included in this annual

report.

Capital Allocation Strategy

Our capital allocation strategy is to prioritize investment in quality assets that meet our return criteria and then stock

repurchases when we believe our stock price is below its intrinsic value. A primary goal of our capital allocation strategy is to increase
our Adjusted Funds From Operations per share. To achieve this, we expect we would continue to deploy capital between portfolio
growth and stock repurchases, subject to compliance with REIT distribution requirements, available funds and market conditions,
while maintaining our target leverage levels. Key elements of our capital allocation strategy include:

Portfolio Growth. We intend to continue to grow our tower portfolio, domestically and internationally, through tower

acquisitions and the construction of new towers.

Stock repurchase program. We currently utilize stock repurchases as part of our capital allocation policy when we believe our
share price is below intrinsic value. After portfolio growth, we believe that share repurchases, when purchased at the right price, will
facilitate our goal of increasing our Adjusted Funds From Operations per share.

Critical Accounting Policies and Estimates

We have identified the policies and significant estimation processes below as critical to our business operations and the

understanding of our results of operations. The listing is not intended to be a comprehensive list. In many cases, the accounting
treatment of a particular transaction is specifically dictated by accounting principles generally accepted in the United States, with no
need for management’s judgment in their application. In other cases, management is required to exercise judgment in the application
of accounting principles with respect to particular transactions. The impact and any associated risks related to these policies on our
business operations is discussed throughout “Management’s Discussion and Analysis of Financial Condition and Results of
Operations” where such policies affect reported and expected financial results. For a detailed discussion on the application of these
and other accounting policies, see Note 2 of our Consolidated Financial Statements for the year ended December 31, 2016, included
herein. Our preparation of our financial statements requires us to make estimates and assumptions that affect the reported amount of
assets and liabilities, disclosure of contingent assets and liabilities at the date of our financial statements, and the reported amounts of
revenue and expenses during the reporting periods. Management bases its estimates on historical experience and on various other
assumptions that are believed to be reasonable under the circumstances. There can be no assurance that actual results will not differ
from those estimates and such differences could be significant.

Revenue Recognition and Accounts Receivable

Revenue from site leasing is recorded monthly and recognized on a straight-line basis over the current term of the related lease

agreements, which are generally five to ten years. Receivables recorded related to the straight-lining of site leases are reflected in other
assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated
Balance Sheets.

Site development projects in which we perform consulting services include contracts on a time and materials basis or a fixed

price basis. Time and materials based contracts are billed at contractual rates and revenue is recognized as the services are rendered.
For those site development contracts in which we perform work on a fixed price basis, site development billing (and revenue
recognition) is based on the completion of agreed upon phases of the project on a per site basis. Upon the completion of each phase on
a per site basis, we recognize the revenue related to that phase. Site development projects generally take from 3 to 12 months to
complete. Amounts billed in advance (collected or uncollected) are recorded as deferred revenue on our Consolidated Balance Sheets.

Revenue from construction projects is recognized on the percentage-of-completion method of accounting, determined by the
percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because

29

management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates,
and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. The asset “costs and
estimated earnings in excess of billings on uncompleted contracts” represents costs incurred and revenues recognized in exces s of
amounts billed. The liability “billings in excess of costs and estimated earnings on uncompleted contracts,” included within other
current liabilities on our Consolidated Balance Sheets, represents billings in excess of costs incurred and revenues recognized.
Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be probable.

We perform periodic credit evaluations of our customers. We monitor collections and payments from our customers and
maintain a provision for estimated credit losses based upon historical experience, specific customer collection issues identified, and
past due balances as determined based on contractual terms. Interest is charged on outstanding receivables from customers on a case
by case basis in accordance with the terms of the respective contracts or agreements with those customers. Amounts determined to be
uncollectible are written off against the allowance for doubtful accounts in the period in which uncollectibility is determined to be
probable.

Asset Impairment

We evaluate individual long-lived and related assets with finite lives for indicators of impairment to determine when an
impairment analysis should be performed. We evaluate our tower assets and current contract intangibles at the tower level, which is
the lowest level for which identifiable cash flows exists. We evaluate our network location intangibles for impairment at the tower
leasing business level whenever indicators of impairment are present. We have established a policy to at least annually evaluate our
tower assets and current contract intangibles for impairment.

We record an impairment charge when we believe an investment in towers or related assets has been impaired, such that future
undiscounted cash flows would not recover the then current carrying value of the investment in the tower and related intangible. If the
future undiscounted cash flows are lower than the carrying value of the investment in the tower and related intangible, we calculate
future discounted cash flows and compare those amounts to the carrying value. We record an impairment charge for any amounts
lower than the carrying value. Estimates and assumptions inherent in the impairment evaluation include, but are not limited to, general
market and economic conditions, historical operating results, geographic location, lease-up potential, and expected timing of lease-up.
In addition, we make certain assumptions in determining an asset’s fair value for the purpose of calculating the amount of an
impairment charge.

Business Combinations

We account for business combinations under the acquisition method of accounting. The assets and liabilities we acquire are

recorded at fair market value at the date of each acquisition and the results of operations of the acquired assets are included with our
results of operations from the dates of the respective acquisitions. We continue to evaluate all acquisitions for a period not to exceed
one year after the applicable closing date of each transaction to determine whether any additional adjustments are needed to the
allocation of the purchase price paid for the assets acquired and liabilities assumed as a result of information available at the
acquisition date. The intangible assets represent the value associated with the current leases at the acquisition date (“Current contract
intangibles”) and future tenant leases anticipated to be added to the communication sites (“Network location intangibles”) and were
calculated using the discounted values of the current or future expected cash flows. The intangible assets are estimated to have a useful
life consistent with the useful life of the related communication site assets, which is typically 15 years.

In connection with certain acquisitions, we may agree to pay contingent consideration (or earnouts) in cash or stock if the

communication sites or businesses that are acquired meet or exceed certain performance targets over a period of one to three years
after they have been acquired. We accrue for contingent consideration in connection with acquisitions at fair value as of the date of the
acquisition. All subsequent changes in fair value of contingent consideration are recorded through Consolidated Statements of
Operations.

In September 2015, the FASB issued ASU 2015-16 Business Combinations. The standard requires that the acquirer (1)
recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the
adjustment amounts are determined, (2) record, in the same period’s financial statements, the effect on earnings of changes in
depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the
accounting had been completed at the acquisition date, and (3) to present separately on the face of the income statement or disclose in
the notes the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous
reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. We adopted ASU 2015-
16 effective January 1, 2016. The financial statement impact of adopting this standard was not material for all periods presented.

30

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business. The standard provides guidance to

help entities determine whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The standard
is effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. The standard is
required to be applied prospectively. We are evaluating the standard, including the impact on its consolidated financial statements.

RESULTS OF OPERATIONS

This report presents our financial results and other financial metrics after eliminating the impact of changes in foreign currency

exchange rates.  We believe that providing these financial results and metrics on a constant currency basis, which are non-GAAP
measures, gives management and investors the ability to evaluate the performance of our business without the impact of foreign
currency exchange rate fluctuations.  We eliminate the impact of changes in foreign currency exchange rates by dividing the current
period’s financial results by the average monthly exchange rates of the prior year period.

Domestic site leasing revenues increased $37.1 million for the year ended December 31, 2016, as compared to the prior year,
due largely to (i) revenues from 951 towers acquired and 183 towers built since January 1, 2015 and (ii) organic site leasing growth,
primarily from monetary lease amendments for additional equipment added to our towers as well as new leases and contractual rent
escalators, partially offset by lease non-renewals in 2015 primarily related to carrier consolidation, including Sprint’s iDEN network,
which impacted our year-over-year growth rates during 2016.

International site leasing revenues increased $20.3 million for the year ended December 31, 2016, as compared to the prior year.

On a constant currency basis, international site leasing revenues increased $30.6 million. These changes were primarily due to (i)
revenues from 473 towers acquired and 640 towers built since January 1, 2015, (ii) organic site leasing growth from new leases and
contractual escalators, and (iii) an increase in reimbursable pass-through expenses. Site leasing revenue in Brazil represented 11.6% of
total site leasing revenue for the period.  No other individual international market represented more than 3% of our total site leasing
revenue.

Site development revenues decreased $62.8 million for the year ended December 31, 2016, as compared to the prior year, as a

result of a decrease in the volume of work performed, particularly as it related to Sprint.

31

Operating Profit

Domestic site leasing segment operating profit increased $28.7 million for the year ended December 31, 2016, as compared to

the prior year, primarily due to additional profit generated by (i) towers acquired and built since January 1, 2015 and organic site
leasing growth as noted above, (ii) continued control of our site leasing cost of revenue, and (iii) the positive impact of our ground
lease purchase program.

International site leasing segment operating profit increased $11.2 million for the year ended December 31, 2016, as compared

to the prior year. On a constant currency basis, international site leasing segment operating profit increased $17.9 million. These
changes were primarily due to towers acquired and built since January 1, 2015 and organic site leasing growth as noted above,
partially offset by increases in cost of revenues.

Site development segment operating profit decreased $21.7 million for the year ended December 31, 2016, as compared to the

prior year, primarily due to a decrease in the volume of work performed, particularly as it related to Sprint.

Selling, general, and administrative expenses increased $28.4 million for the year ended December 31, 2016, as compared to the

prior year. On a constant currency basis, selling, general, and administrative expenses increased $28.7 million. These changes were
primarily as a result of the $16.5 million Oi reserve recorded in the second quarter of 2016 as well as increases in REIT conversion
related costs, bad debt expense, non-cash compensation, and other support costs due in large part to our continued portfolio expansion.

prior year. On a constant currency basis, acquisition related adjustments and expenses increased $1.4 million. These changes were
primarily as a result of an increase in the number of international towers we acquired and changes in our estimated pre-acquisition
contingencies as compared to the prior year, partially offset by a decrease in the number of domestic towers we acquired.

Asset impairment and decommission costs decreased $64.5 million, on an actual and constant currency basis, for the year ended

December 31, 2016, as compared to the prior year. These changes were primarily as a result of a $56.7 million impairment charge
recorded in the third quarter of 2015 related to fiber assets acquired in the 2012 Mobilitie transaction, and a $8.9 million gain on the
sale of fiber assets recorded in the current year.

Depreciation, accretion, and amortization expense decreased $21.8 million for the year ended December 31, 2016, as compared

to the prior year. On a constant currency basis, depreciation, accretion, and amortization expense decreased $17.1 million. These
changes were primarily due to a decrease in depreciation associated with assets that became fully depreciated since the prior year,
partially offset by additional depreciation associated with the increase in the number of towers we acquired and built since January 1,
2015.

Interest income increased $7.0 million for the year ended December 31, 2016, as compared to the prior year. On a constant

currency basis, interest income increased $7.4 million. These changes were primarily due to a higher amount of interest bearing
deposits held as compared to the prior year.

Interest expense increased $6.8 million, on an actual and constant currency basis, for the year ended December 31, 2016, as

compared to the prior year, due to the higher average principal amount of cash-interest bearing debt outstanding as compared to the
prior year, primarily resulting from the issuance of the 2015 Term Loan (defined below) in June 2015, the 2015-1C Tower Securities
(defined below) in October 2015, the 2016-1C Tower Securities (defined below) in July 2016, and the 2016 Senior Notes (defined
below) in August 2016, partially offset by the repayment of the 2012-1 Term Loan in November 2015, the 2010-2C Tower Securities
(defined below) in July 2016, the 5.75% Senior Notes (defined below) in August 2016, and the 5.625% Senior Notes (defined below)
in October 2016, and a lower average balance outstanding under the Revolving Credit Facility in the current year.

Non-cash interest expense increased $0.7 million for the year ended December 31, 2016, as compared to the prior year,
primarily due to the amortization of the discount related to the 2015 Term Loan (defined below) issued in June 2015 and the 2016
Senior Notes (defined below) issued in August 2016.

Amortization of deferred financing fees increased $2.0 million for the year ended December 31, 2016, as compared to the prior

year, primarily resulting from the issuance of the 2015 Term Loan (defined below) in June 2015, the 2015-1C Tower Securities
(defined below) in October 2015, the 2016-1C Tower Securities (defined below) in July 2016, and the 2016 Senior Notes (defined

Senior Notes (defined below) in August 2016, and the 5.625% Senior Notes (defined below) in October 2016.

Loss from extinguishment of debt increased $51.9 million for the year ended December 31, 2016, as compared to the prior year,

primarily due to the payment of a $25.8 million call premium and accrued interest on the redemption of the 5.75% Senior Notes, the
write-off of $7.7 million in deferred financing fees related to the 5.75% Senior Notes, the payment of a $14.1 million call premium
and accrued interest on the redemption of the 5.625% Senior Notes, the write-off of $4.1 million in deferred financing fees related to
the 5.625% Senior Notes, and the write-off of $1.0 million in deferred financing fees related to the redemption of the 2010-2C Tower
Securities.

Other income (expense), net includes a $90.0 million gain on the remeasurement of intercompany loans for the year ended
December 31, 2016, while the prior year included a $178.9 million loss. Other income (expense), net for the year ended December 31,

Revenues

Domestic site leasing revenues increased $79.5 million for the year ended December 31, 2015, as compared to the prior year,

due largely to (i) revenues from 1,007 towers acquired and 266 towers built since January 1, 2014 and (ii) organic site leasing growth
from new leases, contractual rent escalators, and monetary lease amendments for additional equipment added to our towers.

International site leasing revenues increased $41.0 million for the year ended December 31, 2015, as compared to the prior year.

On a constant currency basis, international site leasing revenues increased $110.8 million. These changes were due largely to (i)
revenues from 3,916 towers acquired, primarily from the acquisition of 3,648 towers from Oi S.A. in March 2014 and December
2014, and 582 towers built since January 1, 2014, and (ii) organic site leasing growth from new leases, contractual rent escalators, and
monetary lease amendments for additional equipment added to our towers.

Site development revenues decreased $9.0 million for the year ended December 31, 2015, as compared to the prior year, as a

result of a decrease in the volume of work performed due to the timing of our wireless carrier customers’ initiatives.

Operating Profit

Domestic site leasing segment operating profit increased $74.2 million for the year ended December 31, 2015, as compared to

the prior year, primarily due to additional profit generated by (i) towers acquired and built since January 1, 2014 and organic site

35

leasing growth as noted above, (ii) improving control of our site leasing cost of revenue, and (iii) the positive impact of our ground
lease purchase program.

International site leasing segment operating profit increased $22.9 million for the year ended December 31, 2015, as compared

to the prior year. On a constant currency basis, international site leasing segment operating profit increased $69.9 million. These
changes were primarily due to additional profit generated by (i) towers acquired and built since January 1, 2014 and organic site
leasing growth as noted above and (ii) the positive impact of our ground lease purchase program, partially offset by increased costs
resulting from the integration of towers acquired in 2014.

Site development segment operating profit decreased $1.5 million for the year ended December 31, 2015, as compared to the

prior year, primarily due to lower services revenue.

Asset impairment and decommission costs increased $71.0 million for the year ended December 31, 2015, as compared to the

prior year. On a constant currency basis, asset impairment and decommission costs increased $71.1 million. These changes were
primarily as a result of a $56.7 million impairment charge in the third quarter of 2015 related to fiber assets acquired in the 2012
Mobilitie transaction and $7.3 million of additional impairment charges resulting from the Company’s analysis that the future cash
flows would not recover the carrying value of the investment. In addition, the increase in the asset impairment and decommission
costs includes $5.5 million related to higher net book value of towers decommissioned in 2015 as compared to the prior year and $1.2
million in exit costs related to our former corporate headquarters building.

Domestic site leasing operating income decreased $23.9 million for the year ended December 31, 2015, as compared to the prior

year, primarily due to increases in asset impairment and decommission costs, depreciation, accretion, and amortization expense, and
acquisition related adjustments and expenses, partially offset by higher segment operating profit.

International site leasing operating income increased $13.0 million for the year ended December 31, 2015, as compared to the

prior year. On a constant currency basis, international site leasing operating income increased $23.6 million. These changes were
primarily due to higher segment operating profit and a reduction in acquisition related adjustments and expenses and asset impairment
and decommission costs, partially offset by an increase in depreciation, accretion, and amortization expense and selling, general, and
administrative expenses.

Site development operating income decreased $5.9 million for the year ended December 31, 2015, as compared to the prior
year, primarily due to a decrease in segment operating profit, as well as increases in selling, general, and administrative expenses and
depreciation, accretion, and amortization expense.

Interest income increased $3.2 million for the year ended December 31, 2015, as compared to the prior year. On a constant
currency basis, interest income increased $4.8 million. These changes were primarily due to a higher amount of investments held and
a higher average interest rate on those investments as compared to the prior year period.

Interest expense increased $29.8 million for the year ended December 31, 2015, as compared to the prior year. On a constant

currency basis, interest expense increased $29.7 million. These changes were due to the higher average principal amount of cash-
interest bearing debt outstanding for the year ended December 31, 2015 compared to the prior year, primarily resulting from the
issuance of the 2014 Tower Securities in October 2014, the 2015-1C Tower Securities in October 2015, the 2014 Term Loan in March
2014, the 2015 Term Loan in June 2015, and the 2014 Senior Notes in July 2014, partially offset by the full repayment of the 2010-1C
Tower Securities in October 2014, the full redemption of the 8.25% Notes in August 2014, and the settlement of the 4.0% Notes in
October 2014.

Non-cash interest expense decreased $25.6 million for the year ended December 31, 2015, as compared to the prior year,

primarily due to the settlement of the 4.0% Notes in October 2014.

Amortization of deferred financing fees increased $1.6 million for the year ended December 31, 2015, as compared to the prior

year, primarily resulting from the issuance of the 2014 Tower Securities in October 2014, the 2015-1C Tower Securities in October
2015, 2014 Term Loan in March 2014, the 2015 Term Loan in June 2015, and the 2014 Senior Notes in July 2014, partially offset by
the full repayment of the 8.25% Notes in August 2014 and the 2010-1C Tower Securities in October 2014 and the settlement of the
4.0% Notes in October 2014.

Loss from extinguishment of debt decreased $25.4 million for the year ended December 31, 2015, as compared to the prior year,

primarily due to the repayment of the 2010-1C Tower Securities in October 2014, the 2011 Term Loan in February 2014, and the
2012-2 Term Loan in February 2014, settlement of the 4.0% Notes in October 2014, and the early redemption of the 8.25% Notes in
August 2014, partially offset by the early redemption of the 2012-1 Term Loan in November 2015.

Other (expense) income, net includes a $178.9 million loss on the remeasurement of intercompany loans and a $37.2 million
gain realized on the sale of a cost-method investment for the year ended December 31, 2015.The prior year period included a $23.0

38

million loss on the remeasurement of intercompany loans, a $12.5 million gain on the sale of a cost-method investment, and a $17.9
million gain realized on the settlement of two foreign currency contracts entered into to hedge the purchase price of the Oi S.A.
acquisition in Brazil in 2014.

Net loss increased $151.4 million for the year ended December 31, 2015, as compared to the prior year. On a constant currency

basis, net loss decreased $17.8 million. These changes were primarily due to increases in other (expense) income, net, asset

and acquisition related adjustments and expenses, partially offset by an increase in our total segment operating profit as compared to
the prior year period.

NON-GAAP FINANCIAL MEASURES

This report contains information regarding a non-GAAP measure, Adjusted EBITDA. We have provided below a description of

Adjusted EBITDA, a reconciliation of Adjusted EBITDA to its most directly comparable GAAP measure and an explanation as to
why management utilizes this measure. This report also presents our financial results and other financial metrics after eliminating the
impact of changes in foreign currency exchange rates and the Oi reserve recorded in the second quarter of 2016.  We believe that
providing these financial results and metrics on a constant currency basis, which are non-GAAP measures, gives management and
investors the ability to evaluate the performance of our business without the impact of foreign currency exchange rate fluctuations.
We eliminate the impact of changes in foreign currency exchange rates by dividing the current period’s financial results by t he
average monthly exchange rates of the prior year. We believe that excluding the Oi reserve, which represents a $16.5 million one-time
bad debt provision for all amounts owed or potentially owed by Oi prior to the date of Oi’s June 2016 petition for judicial
reorganization, provides management and investors the ability to better analyze our core results without the impact of what we believe
is a non-recurring event.

Adjusted EBITDA

We define Adjusted EBITDA as net income (loss) excluding the impact of non-cash straight-line leasing revenue, non-cash

straight-line ground lease expense, non-cash compensation, net loss from extinguishment of debt, other income and expenses,
acquisition related adjustments and expenses, asset impairment and decommission costs, interest income, interest expenses,
depreciation, accretion, and amortization, and provision for or benefit from taxes.

We believe that Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance.
Adjusted EBITDA is the primary measure used by management (1) to evaluate the economic productivity of our operations and (2) for
purposes of making decisions about allocating resources to, and assessing the performance of, our operations. Management believes
that Adjusted EBITDA helps investors or other interested parties meaningfully evaluate and compare the results of our operations (1)
from period to period and (2) to our competitors, by excluding the impact of our capital structure (primarily interest charges from our
outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our financial results. Management also
believes Adjusted EBITDA is frequently used by investors or other interested parties in the evaluation of REITs. In addition, Adjusted
EBITDA is a component of the calculation that has been used by our lenders to determine compliance with certain covenants under
our Senior Credit Agreement and the indentures relating to the 2014 Senior Notes and 2016 Senior Notes (defined below). Adjusted
EBITDA should be considered only as a supplement to net income computed in accordance with GAAP as a measure of our
performance.

Interest expense includes interest expense, non-cash interest expense, and amortization of deferred financing fees.
Provision for taxes includes $1,643, $1,766, and $1,485 of franchise taxes reflected in selling, general, and administrative
expenses on the Consolidated Statement of Operations for the year ended 2016, 2015, and 2014, respectively.

Adjusted EBITDA, net of the Oi reserve, increased $28.2 million for the year ended December 31, 2016, as compared to the

prior year. On a constant currency basis, adjusted EBITDA, net of the Oi reserve, increased $35.7 million. These changes were
primarily due to increases in domestic and international site leasing segment operating profit, partially offset by an increase in selling,
general, and administrative expenses and a decrease in site development segment operating profit.

Adjusted EBITDA increased $96.0 million for the year ended December 31, 2015, as compared to the prior year. On a constant
currency basis, adjusted EBITDA increased $133.5 million. These changes were primarily due to increases in segment operating profit

40

from our domestic site leasing and international site leasing segments, partially offset by a decrease in our site development segment
operating profit and an increase in our cash selling, general, and administrative expenses.

LIQUIDITY AND CAPITAL RESOURCES

SBAC is a holding company with no business operations of its own. SBAC’s only significant asset is 100% of the outstanding

capital stock of SBA Telecommunications, LLC (“Telecommunications”), which is also a holding company that owns equity interests
in entities that directly or indirectly own all of our domestic and international towers and assets. We conduct all of our business
operations through Telecommunications’ subsidiaries. Accordingly, our only source of cash to pay our obligations, other than
financings, is distributions with respect to our ownership interest in our subsidiaries from the net earnings and cash flow generated by
these subsidiaries.

A summary of our cash flows is as follows:

During the fourth quarter of 2016, the Company adopted an accounting standard update on the presentation of cash and cash
equivalents in the Statement of Cash Flows. The new standard requires cash and cash equivalent balances to include restricted
cash equivalents. The December 31, 2015 and 2014 consolidated statements of cash flows were retrospectively adjusted to
reflect this change.

Operating Activities

Cash provided by operating activities was $742.5 million for the year ended December 31, 2016 as compared to $723.0 million

for the year ended December 31, 2015. The increase was primarily due to increases in segment operating profit from domestic site
leasing and international site leasing operating segments, partially offset by decreased site development segment operating profit,
increased selling, general, and administrative expenses, and increased cash interest payments relating to the higher average amount of
cash-interest bearing debt outstanding.

Excludes $14.1 million, $16.3 million, and $10.8 million spent to extend ground lease terms for the years ended December 31,
2016, 2015, and 2014, respectively.

Subsequent to December 31, 2016, we acquired 42 towers and related assets for $17.3 million in cash.

During fiscal year 2017, we expect to incur non-discretionary cash capital expenditures associated with tower maintenance and

general corporate expenditures of $31.0 million to $41.0 million and discretionary cash capital expenditures, based on current
acquisition obligations, planned new tower construction, forecasted tower augmentations, and forecasted ground lease purchases, of
$200.0 million to $220.0 million as well as potential, additional tower acquisitions not yet under contract. We expect to fund these
cash capital expenditures from cash on hand, cash flow from operations, and borrowings under the Revolving Credit Facility or new
financings. The exact amount of our future cash capital expenditures will depend on a number of factors including amounts necessary
to support our tower portfolio, our new tower build and acquisition programs, and our ground lease purchase program.

Financing Activities

During the year ended December 31, 2016, we borrowed $580.0 million and repaid $190.0 million under the Revolving Credit
Facility. As of December 31, 2016, we had $390.0 million outstanding under the Revolving Credit Facility. Subsequent to December
31, 2016, we repaid $95.0 million of the outstanding balance under the Revolving Credit Facility.

During the year ended December 31, 2016, we repurchased 5.3 million shares of our Class A common stock under our stock
repurchase program for $545.7 million, including commissions, at a weighted average price per share of $102.14. As of December 31,
2016, we had a remaining authorization to repurchase $154.4 million of Class A common stock under our current $1.0 billion stock
repurchase program dated June 4, 2015. Subsequent to December 31, 2016, we repurchased 42,163 shares of our Class A common
stock under our stock repurchase program for $4.4 million at a weighted average price per share of $104.81. Shares purchased were
retired.

On January 12, 2017, the Board of Directors authorized a new stock repurchase plan, replacing the plan authorized on June 4,

2015 which had a remaining authorization of $150.0 million. This plan authorizes us to purchase, from time to time, up to $1.0 billion
of our outstanding Class A common stock through open market repurchases in compliance with Rule 10b-18 under the Securities
Exchange Act of 1934, as amended, and/or in privately negotiated transactions at management’s discretion based on market and
business conditions, applicable legal requirements and other factors. Shares purchased will be retired. The new plan has no time
deadline and will continue until otherwise modified or terminated by our Board of Directors at any time in its sole discretion. As of the
date of this filing, we had the full $1.0 billion authorization remaining under our current stock repurchase program.

On July 7, 2016, we, through our existing SBA Tower Trust, issued $700.0 million of 2.877% Secured Tower Revenue
Securities Series 2016-1C which have an anticipated repayment date of July 9, 2021 and a final maturity date of July 10, 2046 (the
“2016-1C Tower Securities”). Net proceeds from this offering were used to prepay the full $550.0 million outstanding on the 2010-2C
Tower Securities and for general corporate purposes. Additionally, we expensed $1.0 million of deferred financing fees related to the
redemption of the 2010-2C Tower Securities.

42

On August 15, 2016, we issued $1.1 billion of unsecured senior notes due September 1, 2024 (the “2016 Senior Notes”). The
2016 Senior Notes accrue interest at a rate of 4.875% per annum and were issued at 99.178% of par value. Net proceeds from this
offering and cash on hand were used to redeem $800.0 million, the aggregate principal amount outstanding, of Telecommunications’
5.75% Senior Notes and $250.0 million of our 5.625% Senior Notes and pay the associated call premiums. We also paid $25.8 million
for the call premium and accrued interest on the redemption of the 5.75% Senior Notes and expensed $7.7 million of deferred
financing fees related to the redemption of the notes.

On October 1, 2016, we redeemed the 5.625% Senior Notes in full. On October 3, 2016, we repaid $500.0 million in
outstanding principal, $14.1 million related to the call premium on the early redemption of the notes, and $14.1 million in accrued
interest.  Repayment was made using (1) the proceeds from the 2016 Senior Notes, (2) borrowings under the Revolving Credit
Facility, and (3) cash on hand. In addition, we expensed $4.1 million of deferred financing fees in connection with the extinguishment
of the debt.

On January 20, 2017, we repriced our senior secured term loans from a Eurodollar Rate plus 250 basis points (with a Eurodollar

Rate floor of 0.75%) to a Eurodollar Rate plus 225 basis points (with a zero Eurodollar floor).

Registration Statements

We have on file with the Commission a shelf registration statement on Form S-4 registering shares of Class A common stock

that we may issue in connection with the acquisition of wireless communication towers or antenna sites and related assets or
companies who own wireless communication towers, antenna sites, or related assets. During the year ended December 31, 2016, we
did not issue any shares of Class A common stock under this registration statement. As of December 31, 2016, we had approximately
1.7 million shares of Class A common stock remaining under this shelf registration statement.

On March 3, 2015, we filed with the Commission an automatic shelf registration statement for well-known seasoned issuers on
Form S-3ASR. This registration statement enables us to issue shares of our Class A common stock, preferred stock or debt securities
either separately or represented by warrants, or depositary shares as well as units that include any of these securities. Under the rules
governing automatic shelf registration statements, we will file a prospectus supplement and advise the Commission of the amount and
type of securities each time we issue securities under this registration statement. No shares were issued under this registration
statement through the date of this filing.

Debt Instruments and Debt Service Requirements

Senior Credit Agreement

On February 7, 2014, SBA Senior Finance II entered into a Second Amended and Restated Credit Agreement with several banks
and other financial institutions or entities from time to time parties to the Second Amended and Restated Credit Agreement to, among
other things, incur the 2014 Term Loan and amend certain terms of the existing senior credit agreement (as amended, the “Senior
Credit Agreement”).

Terms of the Senior Credit Agreement

The Senior Credit Agreement, as amended, requires SBA Senior Finance II to maintain specific financial ratios, including (1) a

ratio of Consolidated Total Debt to Annualized Borrower EBITDA not to exceed 6.5 times for any fiscal quarter, (2) a ratio of
Consolidated Total Debt and Net Hedge Exposure (calculated in accordance with the Senior Credit Agreement) to Annualized
Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.5 times for 30 consecutive days and (3) a ratio of
Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Senior Credit Agreement) of
not less than 2.0 times for any fiscal quarter. The Senior Credit Agreement contains customary affirmative and negative covenants
that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make
certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into
transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. As of
December 31, 2016, SBA Senior Finance II was in compliance with the financial covenants contained in the Senior Credit Agreement.
The Senior Credit Agreement is also subject to customary events of default. Pursuant to the Second Amended and Restated Guarantee
and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loans and certain hedging transactions
that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Senior Credit Agreement) with
lenders or their affiliates are secured by a first lien on the membership interests of SBA Telecommunications, LLC, SBA Senior
Finance, LLC and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real
property) of SBA Senior Finance II and the Subsidiary Guarantors.

43

The Senior Credit Agreement, as amended, permits SBA Senior Finance II, without the consent of the other lenders, to request

that one or more lenders provide SBA Senior Finance II with increases in the Revolving Credit Facility or additional term loans
provided that after giving effect to the proposed increase in Revolving Credit Facility commitments or incremental term loans the ratio
of Consolidated Total Debt to Annualized Borrower EBITDA would not exceed 6.5 times. SBA Senior Finance II’s ability to request
such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions set forth
in the Senior Credit Agreement including compliance, on a pro forma basis, with the financial covenants and ratios set forth therein
and, with respect to any additional term loan, an increase in the margin on existing term loans to the extent required by the terms of
the Senior Credit Agreement. Upon SBA Senior Finance II’s request, each lender may decide, in its sole discretion, whether to
increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional
term loans and, if so, upon what terms.

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility is governed by the Senior Credit Agreement. The Revolving Credit Facility consists of a
revolving loan under which up to $1.0 billion aggregate principal amount may be borrowed, repaid and redrawn, based upon specific
financial ratios and subject to the satisfaction of other customary conditions to borrowing. Amounts borrowed under the Revolving
Credit Facility accrue interest, at SBA Senior Finance II’s election, at either (i) the Eurodollar Rate plus a margin that ranges from
137.5 basis points to 200.0 basis points or (ii) the Base Rate plus a margin that ranges from 37.5 basis points to 100.0 basis points, in
each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA, calculated in accordance with the Senior
Credit Agreement. In addition, SBA Senior Finance II is required to pay a commitment fee of 0.25% per annum on the amount of
unused commitment. If not earlier terminated by SBA Senior Finance II, the Revolving Credit Facility will terminate on, and SBA
Senior Finance II will repay all amounts outstanding on or before, February 5, 2020. The proceeds available under the Revolving
Credit Facility may be used for general corporate purposes. SBA Senior Finance II may, from time to time, borrow from and repay the
Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of a period may not be
reflective of the total amounts outstanding during such period.

During the year ended December 31, 2016, we borrowed $580.0 million and repaid $190.0 million of the outstanding balance
under the Revolving Credit Facility. As of December 31, 2016, $390.0 million was outstanding under the Revolving Credit Facility.

Subsequent to December 31, 2016, we repaid $95.0 million of the outstanding balance under the Revolving Credit Facility.

Term Loans under the Senior Credit Agreement

Repricing Amendment to the Senior Credit Agreement

On January 20, 2017, we amended our Senior Credit Agreement, primarily to reduce the stated rate of interest applicable to our

senior secured term loans.  As amended, our senior secured term loans accrue interest, at SBA Senior Finance II’s election, at either
the Base Rate plus 125 basis points (with a zero Base Rate floor) or the Eurodollar Rate plus 225 basis points (with a zero Eurodollar
Rate floor).

2014 Term Loan

The 2014 Term Loan consists of a senior secured term loan with an initial aggregate principal amount of $1.5 billion that

matures on March 24, 2021. Prior to the reduction in the term loan interest rates as discussed above, the 2014 Term Loan accrued
interest, at SBA Senior Finance II’s election, at either the Base Rate plus 150 basis points (with a Base Rate floor of 1.75%) or the
Eurodollar Rate plus 250 basis points (with a Eurodollar Rate floor of 0.75%). The 2014 Term Loan was issued at 99.75% of par
value. As of December 31, 2016, the 2014 Term Loan was accruing interest at 3.27% per annum. Principal payments on the 2014
Term Loan commenced on September 30, 2014 and are being made in quarterly installments on the last day of each March, June,
September, and December in an amount equal to $3.8 million. SBA Senior Finance II has the ability to prepay any or all amounts
under the 2014 Term Loan. We incurred deferred financing fees of approximately $12.9 million in relation to this transaction which
are being amortized through the maturity date.

During the year ended December 31, 2016, we repaid $15.0 million of principal on the 2014 Term Loan. As of December 31,

2016, the 2014 Term Loan had a principal balance of $1.5 billion.

44

2015 Term Loan

The 2015 Term Loan consists of a senior secured term loan with an initial aggregate principal amount of $500.0 million that

matures on June 10, 2022. Prior to the reduction in the term loan interest rates as discussed above, the 2015 Term Loan accrued
interest, at SBA Senior Finance II’s election, at either the Base Rate plus 150 basis points (with a Base Rate floor of 1.75%) or the
Eurodollar Rate plus 250 basis points (with a Eurodollar Rate floor of 0.75%). The 2015 Term Loan was issued at 99.0% of par value.
As of December 31, 2016, the 2015 Term Loan was accruing interest at 3.27% per annum. Principal payments on the 2015 Term Loan
commenced on September 30, 2015 and are being made in quarterly installments on the last day of each March, June, September, and
December in an amount equal to $1.3 million. SBA Senior Finance II has the ability to prepay any or all amounts under the 2015 Term
Loan. We incurred deferred financing fees of approximately $5.1 million in relation to this transaction which are being amortized
through the maturity date.

During the year ended December 31, 2016, we repaid $5.0 million of principal on the 2015 Term Loan. As of December 31,

2016, the 2015 Term Loan had a principal balance of $492.5 million.

Secured Tower Revenue Securities

Tower Revenue Securities Terms

The mortgage loan underlying the 2012-1C Tower Securities, 2013 Tower Securities, 2014 Tower Securities, 2015-1C Tower

Securities, and 2016-1C Tower Securities (together the “Tower Securities”) will be paid from the operating cash flows from the
aggregate 10,535 tower sites owned by the Borrowers. The mortgage loan is secured by (i) mortgages, deeds of trust, and deeds to
secure debt on a substantial portion of the tower sites, (ii) a security interest in the tower sites and substantially all of the Borrowers’
personal property and fixtures, (iii) the Borrowers’ rights under certain tenant leases, and (iv) all of the proceeds of the foregoing. For
each calendar month, SBA Network Management, Inc., an indirect subsidiary (“Network Management”), is entitled to receive a
management fee equal to 4.5% of the Borrowers’ operating revenues for the immediately preceding calendar month.

The Borrowers may prepay any of the mortgage loan components, in whole or in part, with no prepayment consideration,
(i) within twelve months (in the case of the component corresponding to the Secured Tower Revenue Securities Series 2012-1C,
Secured Tower Revenue Securities Series 2013-1C, Secured Tower Revenue Securities Series 2013-1D, Secured Tower Revenue
Securities Series 2014-1C, Secured Tower Revenue Securities Series 2015-1C, and Secured Tower Revenue Securities Series 2016-
1C) or eighteen months (in the case of the components corresponding to the Secured Tower Revenue Securities Series 2013-2C and
Secured Tower Revenue Securities Series 2014-2C) of the anticipated repayment date of such mortgage loan component, (ii) with
proceeds received as a result of any condemnation or casualty of any tower owned by the Borrowers or (iii) during an amortization
period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable
prepayment consideration. The prepayment consideration is determined based on the class of the Tower Securities to which the
prepaid mortgage loan component corresponds and consists of an amount equal to the excess, if any, of (1) the present value
associated with the portion of the principal balance being prepaid, calculated in accordance with the formula set forth in the mortgage
loan agreement, on the date of prepayment of all future installments of principal and interest required to be paid from the date of
prepayment to and including the first due date within twelve months (in the case of the component corresponding to the Secured
Tower Revenue Securities Series 2012-1C, Secured Tower Revenue Securities Series 2013-1C, Secured Tower Revenue Securities
Series 2013-1D, Secured Tower Revenue Securities Series 2014-1C, Secured Tower Revenue Securities Series 2015-1C, and Secured
Tower Revenue Securities Series 2016-1C) or eighteen months (in the case of the components corresponding to the Secured Tower
Revenue Securities Series 2013-2C and Secured Tower Revenue Securities Series 2014-2C) of the anticipated repayment date of such
mortgage loan component over (2) that portion of the principal balance of such class prepaid on the date of such prepayment.

To the extent that the mortgage loan components corresponding to the Tower Securities are not fully repaid by their respective

anticipated repayment dates, the interest rate of each such component will increase by the greater of (i) 5% and (ii) the amount, if any,
by which the sum of (x) the ten-year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the
mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the Tower Securities, all rents and other sums due on any of the towers owned by the Borrowers are

directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the
indenture trustee after the release date are classified as short-term restricted cash on the Consolidated Balance Sheets (see Note 4).
However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the
amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding
twelve months, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make
debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other

45

payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of
being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service
Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the
end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be
applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. In
addition, if any of the Tower Securities are not fully repaid by their respective anticipated repayment dates, the cash flow from the
towers owned by the Borrowers will be trapped by the trustee for the Tower Securities and applied first to repay the interest, at the
original interest rates, on the mortgage loan components underlying the Tower Securities, second to fund all reserve accounts and
operating expenses associated with those towers, third to pay the management fees due to Network Management, fourth to repay
principal of the Tower Securities and fifth to repay the additional interest discussed above. Furthermore, the advance rents reserve
requirement states that the Borrowers are required to maintain an advance rents reserve at any time the monthly tenant Debt Service
Coverage Ratio is equal to or less than 2:1 and for two calendar months after such coverage ratio again exceeds 2:1. The mortgage
loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other
things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. As of
December 31, 2016, the Borrowers met the required Debt Service Coverage Ratio as set forth in the mortgage loan agreement and
were in compliance with all other covenants as set forth in the agreement.

2010-2C Tower Securities

On April 16, 2010, we, through a New York common law trust (the “Trust”), issued $550.0 million of Secured Tower Revenue

Additionally, we expensed $7.7 million of deferred financing fees related to the redemption of the notes. The call premium and the
write-off of deferred financing fees are reflected in loss from extinguishment of debt on the Consolidated Statement of Operations.

SBAC is a holding company with no business operations of its own and its only significant asset is the outstanding capital stock

of Telecommunications. Telecommunications is 100% owned by SBAC. SBAC had fully and unconditionally guaranteed the Senior
Notes issued by Telecommunications.

5.625% Senior Notes

On September 28, 2012, we issued $500.0 million of unsecured senior notes due October 1, 2019 (the “5.625% Senior Notes”).

Indentures Governing Senior Notes

The Indentures governing the Senior Notes contain customary covenants, subject to a number of exceptions and qualifications,

including restrictions on the ability of SBAC and Telecommunications to (1) incur additional indebtedness unless the Consolidated
Indebtedness to Annualized Consolidated Adjusted EBITDA Ratio (as defined in the Indenture), pro forma for the additional
indebtedness does not exceed, with respect to any fiscal quarter, 9.5x for SBAC, (2) merge, consolidate or sell assets, (3) make
restricted payments, including dividends or other distributions, (4) enter into transactions with affiliates, and (5) enter into sale and
leaseback transactions and restrictions on the ability of the Restricted Subsidiaries of SBAC (as defined in the Indentures) to incur
liens securing indebtedness.

Debt Service

As of December 31, 2016, we believe that our cash on hand, capacity available under our Revolving Credit Facility, and cash

flows from operations for the next twelve months will be sufficient to service our outstanding debt during the next twelve months.

48

The following table illustrates our estimate of our debt service requirement over the twelve months ended December 31, 2017

based on the amounts outstanding as of December 31, 2016 and the interest rates accruing on those amounts on such date (in

(2) Amounts include interest payments based on the 2014 Term Loan and 2015 Term Loan accruing interest at a rate of 3.27% as of
December 31, 2016. However, as a result of the repricing of our senior secured term loans discussed above, the 2014 Term Loan
and 2015 Term Loan were accruing interest at a rate of 3.04% as of March 1, 2017.

Inflation

The impact of inflation on our operations has not been significant to date. However, we cannot assure you that a high rate of
inflation in the future will not adversely affect our operating results particularly in light of the fact that our site leasing revenues are

respectively.

Our current primary market risk exposure is (1) interest rate risk relating to our ability to refinance our debt at commercially

reasonable rates, if at all, and (2) interest rate risk relating to the impact of interest rate movements on our 2014 Term Loan and 2015
Term Loan and any borrowings that we may incur under our Revolving Credit Facility, which are at floating rates. We manage the
interest rate risk on our outstanding debt through our large percentage of fixed rate debt. While we cannot predict our ability to
refinance existing debt or the impact interest rate movements will have on our existing debt, we continue to evaluate our financial
position on an ongoing basis.

We are exposed to market risk from changes in foreign currency exchange rates in connection with our operations in Brazil,

Canada, and Chile, and to a lesser extent, our markets in Central America. In each of these countries, we pay most of our selling,

50

general, and administrative expenses and a portion of our operating expenses, such as taxes and utilities incurred in the country in
local currency. In addition, in Brazil, Canada, and Chile, we receive significantly all of our revenue and pay significantly all of our
operating expenses in local currency. All transactions denominated in currencies other than the U.S. Dollar are reported in U.S.
Dollars at the applicable exchange rate. All assets and liabilities are translated into U.S. Dollars at exchange rates in effect at the end
of the applicable fiscal reporting period, and all revenues and expenses are translated at average rates for the period. The cumulative
translation effect is included in equity as a component of Accumulated other comprehensive income (loss). For the year ended
December 31, 2016, approximately 11.6% of our revenues and approximately 14.9% of our total operating expenses were
denominated in foreign currencies.

We have performed a sensitivity analysis assuming a hypothetical 10% adverse movement in the Brazilian Real from the quoted

foreign currency exchange rates at December 31, 2016. As of December 31, 2016, the analysis indicated that such an adverse
movement would have caused our revenues and operating income to fluctuate by approximately 0.7% and 2.0%, respectively, for the
year ended December 31, 2016.

As of December 31, 2016, we had intercompany debt, which is denominated in a currency other than the functional currency of
the subsidiary in which it is recorded. As settlement of this debt is anticipated or planned in the foreseeable future, any changes in the
foreign currency exchange rates will result in unrealized gains or losses, which will be included in our determination of net income. A
change of 10% in the underlying exchange rates of our unsettled intercompany debt at December 31, 2016 would have resulted in
approximately $42.0 million of unrealized gains or losses that would have been included in Other income (expense), net in our
consolidated statements of operations for the year ended December 31, 2016.

growth on our financial and operational results, and our intent to grow our tower portfolio domestically and

our belief that our site leasing business is characterized by stable and long-term recurring revenues, predictable operating
costs, and minimal non-discretionary capital expenditures, and our expectations regarding levels of site leasing revenue;

maintain these towers will be minimal;

expenditures, and the source of funds for these expenditures;

our intended use of our liquidity;

under our Revolving Credit Facility, and our cash flows from operations for the next twelve months will be sufficient to
service our outstanding debt during the next twelve months;

our belief regarding our credit risk; and

our estimates regarding certain accounting and tax matters.

These forward-looking statements reflect our current views about future events and are subject to risks, uncertainties and

assumptions. We wish to caution readers that certain important factors may have affected and could in the future affect our actual
results and could cause actual results to differ significantly from those expressed in any forward-looking statement. The most
important factors that could prevent us from achieving our goals, and cause the assumptions underlying forward-looking statements
and the actual results to differ materially from those expressed in or implied by those forward-looking statements include, but are not
limited to, the following:

customers and to successfully and timely address zoning, permitting, weather, availability of labor and supplies and other
issues that arise in connection with the building of new towers;

competition for the acquisition of towers and other factors that may adversely affect our ability to purchase towers that
meet our investment criteria and are available at prices which we believe will be accretive to our shareholders and allow
us to maintain our long-term target leverage ratios;

our ability to protect our rights to the land under our towers, and our ability to acquire land underneath our towers on
terms that are accretive;

our ability to sufficiently increase our revenues and maintain expenses and cash capital expenditures at appropriate levels
to permit us to meet our anticipated uses of liquidity for operations, debt service and estimated portfolio growth;

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL
DISCLOSURE

None.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures – We maintain disclosure controls and procedures that are designed to ensure that
information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), is
recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such
information is accumulated and communicated to management, including our Chief Executive Officer (“CEO”) and Chief Financial
Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure
controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can
provide only reasonable assurance of achieving the desired control objectives, as ours are designed to do, and management necessarily
was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

53

In connection with the preparation of this Annual Report on Form 10-K, as of December 31, 2016, an evaluation was performed

under the supervision and with the participation of our management, including the CEO and CFO, of the effectiveness of our
disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act). Based on such evaluation, our CEO and
CFO concluded that, as of December 31, 2016, our disclosure controls and procedures were effective.

There has been no change in our internal control over financial reporting during the quarter ended December 31, 2016 that has

materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Management’s Annual Report on Internal Control over Financial Reporting – Management is responsible for establishing

and maintaining adequate internal control over financial reporting, and for performing an assessment of the effectiveness of internal
control over financial reporting as of December 31, 2016. 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. Our system of 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 SBAC; (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 SBAC are being made only in accordance with authorizations of management and directors of SBAC; and
(iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of SBAC’s
assets that could have a material effect on the financial statements.

Management performed an assessment of the effectiveness of SBAC’s internal control over financial reporting as of December
31, 2016 based upon criteria in Internal Control –Integrated Framework (2013 Framework) issued by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO). Based on our assessment, management determined that SBAC’s internal control
over financial reporting was effective as of December 31, 2016 based on the criteria in Internal Control –Integrated Framework
(2013 Framework) issued by COSO.

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.

Ernst & Young LLP, the independent registered public accounting firm that audited the financial statements included in this

Annual Report on Form 10-K, has issued an attestation report on SBAC’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Shareholders of SBA Communications Corporation and Subsidiaries

We have audited SBA Communications Corporation and Subsidiaries’ internal control over financial reporting as of December

31, 2016, based on criteria established in Internal Control Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (2013 framework) (the COSO criteria). SBA Communications Corporation and
Subsidiaries’ management is responsible for maintaining effective internal control over financial reporting, and for its assessment of
the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal
Control over Financial Reporting. Our responsibility is to express an opinion on the company’s internal control over financial
reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).

Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control
over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over
financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of
internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances.
We believe that our audit provides a reasonable basis for our opinion.

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 (1)
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the
assets of the company; (2) 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 (3) 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.

In our opinion, SBA Communications Corporation and Subsidiaries maintained, in all material respects, effective internal

control over financial reporting as of December 31, 2016, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the
consolidated balance sheets of SBA Communications Corporation and Subsidiaries as of December 31, 2016 and 2015 and the related
consolidated statements of operations, comprehensive income (loss), shareholders’ equity (deficit) and cash flows for each of the three
years in the period ended December 31, 2016 of SBA Communications Corporation and Subsidiaries and our report dated March 1,
2017 expressed an unqualified opinion thereon.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders of SBA Communications Corporation and Subsidiaries

We have audited the accompanying consolidated balance sheets of SBA Communications Corporation and Subsidiaries as of

December 31, 2016 and 2015, and the related consolidated statements of operations, comprehensive income (loss), shareholders’
equity (deficit) and cash flows for each of the three years in the period ended December 31, 2016. These financial statements are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our
audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those
standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of
SBA Communications Corporation and Subsidiaries at December 31, 2016 and 2015, and the consolidated results of their operations
and their cash flows for each of the three years in the period ended December 31, 2016, in conformity with U.S. generally accepted
accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), SBA
Communications Corporation and Subsidiaries’ internal control over financial reporting as of December 31, 2016, based on criteria
established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (2013 framework), and our report dated March 1, 2017 expressed an unqualified opinion thereon.

GENERAL

SBA COMMUNICATIONS CORPORATION AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

SBA Communications Corporation (the “Company” or “SBAC”) was incorporated in the State of Florida in March 1997. The

Company is a holding company that holds all of the outstanding capital stock of SBA Telecommunications, LLC
(“Telecommunications”). Telecommunications is a holding company that holds the outstanding capital stock of SBA Senior Finance,
LLC (“SBA Senior Finance”), and other operating subsidiaries which are not a party to any loan agreement. SBA Senior Finance is a
holding company that holds, directly or indirectly, the equity interest in certain subsidiaries that issued the Tower Securities (see Note
12) and certain subsidiaries that were not involved in the issuance of the Tower Securities. With respect to the subsidiaries involved in
the issuance of the Tower Securities, SBA Senior Finance is the sole member of SBA Holdings, LLC and SBA Depositor, LLC. SBA
Holdings, LLC is the sole member of SBA Guarantor, LLC. SBA Guarantor, LLC directly or indirectly holds all of the capital stock of
the companies referred to as the “Borrowers” under the Tower Securities. With respect to subsidiaries not involved in the issuance of
the Tower Securities, SBA Senior Finance holds all of the membership interests in SBA Senior Finance II, LLC (“SBA Senior
Finance II”) and certain non-operating subsidiaries. SBA Senior Finance II holds, directly or indirectly, all the capital stock of certain
international subsidiaries and certain other tower companies (known as “Tower Companies”). SBA Senior Finance II also holds,
directly or indirectly, all the capital stock and/or membership interests of certain other subsidiaries involved in providing services,
including SBA Network Services, LLC (“Network Services”) as well as SBA Network Management, Inc. (“Network Management”)
which manages and administers the operations of the Borrowers.

In October 2016, the Company announced its intention to take the necessary steps to qualify as a Real Estate Investment Trust

(“REIT”) for U.S. federal income tax purposes. This is referred to as the REIT conversion. The Company believes that its business has
been operated in a manner that complies with the REIT rules since January 1, 2016, and as a result, intends to make the election to be
subject to tax as a REIT commencing with its taxable year ending December 31, 2016. Because the Company believes its business is
currently operated in a manner that complies with the REIT rules, no further reorganization of its operations is necessary to complete
the REIT conversion. As part of the REIT conversion, effective January 13, 2017, the Company completed the merger with its
predecessor that was approved by its shareholders at a special meeting held on January 12, 2017, and as a result of the merger, the
Company now holds, directly or indirectly through its subsidiaries, the assets held by its predecessor prior to the merger and conducts
the existing businesses of its predecessor and its subsidiaries. Although the REIT rules do not require the completion of this merger,
the Company completed the merger to facilitate its compliance with the REIT rules by ensuring the effective adoption of certain
REIT-related ownership limitations and transfer restrictions related to our capital stock.

As of December 31, 2016, the Company owned and operated wireless towers in the United States and its territories. In addition,
the Company owned towers in Brazil, Canada, Chile, Costa Rica, Ecuador, El Salvador, Guatemala, Nicaragua, and Panama. Space on
these towers is leased primarily to wireless service providers. As of December 31, 2016, the Company owned and operated 26,197
towers of which 15,922 are domestic and 10,275 are international.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies applied in the preparation of the accompanying consolidated financial

statements is as follows:

Principles of Consolidation

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the
United States of America (“U.S. GAAP”) and include the Company and its majority and wholly-owned subsidiaries. All significant
intercompany accounts and transactions have been eliminated in consolidation.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates

and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. The significant
estimates made by management relate to the allowance for doubtful accounts, the costs and revenue relating to the Company’s
construction contracts, stock-based compensation assumptions, valuation allowance related to deferred tax assets, fair value of long-
lived assets, the useful lives of towers and intangible assets, anticipated property tax assessments, fair value of investments and asset
retirement obligations. Management develops estimates based on historical experience and on various assumptions about the future
that are believed to be reasonable based on the information available. These estimates ultimately may differ from actual results and
such differences could be material.

F-8

Cash and Cash Equivalents

Cash and cash equivalents consist primarily of cash in banks, money market funds, commercial paper, highly liquid short-term

investments, and other marketable securities with an original maturity of three months or less at the time of purchase. These
investments are carried at cost, which approximates fair value.

Restricted Cash

The Company classifies all cash pledged as collateral to secure certain obligations and all cash whose use is limited as restricted

cash. This includes cash held in escrow to fund certain reserve accounts relating to the Tower Securities as well as for payment and
performance bonds and surety bonds issued for the benefit of the Company in the ordinary course of business, as well as collateral
associated with workers’ compensation plans (see Note 4).

Investments

Investment securities with original maturities of more than three months but less than one year at time of purchase are

considered short-term investments. The Company’s short-term investments primarily consist of certificates of deposit with maturities
of less than a year. Investment securities with maturities of more than a year are considered long-term investments and are classified in
other assets on the accompanying Consolidated Balance Sheets. Long-term investments primarily consist of U.S. Treasuries, mutual
funds, and preferred securities. Gross purchases and sales of the Company’s investments are presented within “Cash flows from
investing activities” on the Company’s Consolidated Statements of Cash Flows.

The Company accounts for its investments in privately held companies under the cost-method as it does not exert significant
influence. The Company evaluates its cost-method investments for impairment at least annually. The Company determines the fair
value of its cost-method investments by considering available evidence, including general market conditions, the investee’s financial
condition, near-term prospects, market comparables and subsequent rounds of financing. The Company measures and records its cost-
method investments at fair value when they are deemed to be other-than-temporarily impaired. The Company did not recognize any
impairment loss associated with its cost-method investments during the years ended December 31, 2016, 2015, and 2014.

During the years ended December 31, 2016 and 2015, the Company received proceeds related to the sale or maturity of
investments of $0.7 million and $89.7 million, respectively, and recorded a gain of $38.3 million in the year ended December 31,
2015. During the year ended December 31, 2016, no gain or loss was recorded related to the sale or maturity of investments. The
proceeds are reflected in Net cash used in investing activities on the Consolidated Statements of Cash Flows, and the related gain or
loss on sale or maturity is reflected in Other income (expense), net in the accompanying Consolidated Statement of Operations. The
aggregate carrying value of the Company’s investments was approximately $8.1 million and $8.8 million as of December 31, 2016
and 2015, respectively, and is classified within short-term investments and other assets on the Company’s consolidated balance sheets.

Property and Equipment

Property and equipment are recorded at cost or at estimated fair value (in the case of acquired properties), adjusted for asset

impairment and estimated asset retirement obligations. Costs for self-constructed towers include direct materials and labor, indirect
costs and capitalized interest. Approximately $1.0 million, $0.8 million, and $0.3 million of interest cost was capitalized in 2016, 2015
and 2014, respectively.

Depreciation on towers and related components is provided using the straight-line method over the estimated useful lives, not to

exceed the minimum lease term of the underlying ground lease. The Company defines the minimum lease term as the shorter of the
period from lease inception through the end of the term of all tenant lease obligations in existence at ground lease inception, including
renewal periods, or the ground lease term, including renewal periods. If no tenant lease obligation exists at the date of ground lease
inception, the initial term of the ground lease is considered the minimum lease term. Leasehold improvements are amortized on a
straight-line basis over the shorter of the useful life of the improvement or the minimum lease term of the lease. For all other property
and equipment, depreciation is provided using the straight-line method over the estimated useful lives.

The Company performs ongoing evaluations of the estimated useful lives of its property and equipment for depreciation
purposes. The estimated useful lives are determined and continually evaluated based on the period over which services are expected to
be rendered by the asset. If the useful lives of assets are reduced, depreciation may be accelerated in future years. Property and
equipment under capital leases are amortized on a straight-line basis over the term of the lease or the remaining estimated life of the
leased property, whichever is shorter, and the related amortization is included in depreciation expense. Expenditures for maintenance
and repair are expensed as incurred.

F-9

Asset classes and related estimated useful lives are as follows:

Towers and related components
Furniture, equipment and vehicles
Buildings and improvements

3 - 15 years
2 - 7 years
5 - 30 years

Betterments, improvements, and significant repairs, which increase the value or extend the life of an asset, are capitalized and
depreciated over the remaining estimated useful life of the respective asset. Changes in an asset’s estimated useful life are accounted
for prospectively, with the book value of the asset at the time of the change being depreciated over the revised remaining useful life.
There has been no material impact for changes in estimated useful lives for any years presented.

Deferred Financing Fees

Financing fees related to the issuance of debt have been deferred and are being amortized using the effective interest rate

method over the expected duration of the related indebtedness (see Note 12).

In April 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-03, Interest—Imputation of Interest. The

standard requires debt issuance costs to be presented on the balance sheet as a direct deduction from the related debt liability rather
than as an asset. The Company adopted ASU 2015-03 effective January 1, 2016 and reclassified $90.2 million from deferred financing
fees, net to long-term debt in the December 31, 2015 Consolidated Balance Sheet.

In August 2015, the FASB issued ASU 2015-15, Interest - Imputation of Interest - Presentation and Subsequent Measurement of

Debt Issuance Costs Associated with Line-of-Credit Arrangements. The standard indicates the Securities and Exchange Commission
(the “Commission”) staff would not object to presenting debt issuance costs for a line of credit arrangement as an asset in the balance
sheet. The Company adopted ASU 2015-15 effective January 1, 2016 and has elected to continue to present debt issuance costs for its
Revolving Credit Facility as an asset on the accompanying Consolidated Balance Sheet.

Deferred Lease Costs

The Company defers certain initial direct costs associated with the origination of tenant leases and lease amendments and
amortizes these costs over the initial lease term or over the lease term remaining if related to a lease amendment. Such deferred costs
were approximately $10.2 million, $10.9 million, and $12.4 million in 2016, 2015, and 2014, respectively. Amortization expense was
$11.3 million, $9.0 million, and $6.8 million for the years ended December 31, 2016, 2015 and 2014, respectively, and is included in
cost of site leasing on the accompanying Consolidated Statements of Operations. As of December 31, 2016 and 2015, unamortized
deferred lease costs were $29.7 million and $30.6 million, respectively, and are included in other assets on the accompanying
Consolidated Balance Sheets.

Intangible Assets

The Company classifies as intangible assets the fair value of current leases in place at the acquisition date of towers and related

assets (referred to as the “Current contract intangibles”), and the fair value of future tenant leases anticipated to be added to the
acquired towers (referred to as the “Network location intangibles”). These intangibles are estimated to have a useful life co nsistent
with the useful life of the related tower assets, which is typically 15 years. For all intangible assets, amortization is provided using the
straight-line method over the estimated useful lives as the benefit associated with these intangible assets is anticipated to be derived
evenly over the life of the asset.

Impairment of Long-Lived Assets

The Company evaluates its individual long-lived and related assets with finite lives for indicators of impairment to determine
when an impairment analysis should be performed. The Company evaluates its tower assets and Current contract intangibles at the
tower level, which is the lowest level for which identifiable cash flows exists. The Company evaluates its Network location
intangibles for impairment at the tower leasing business level whenever indicators of impairment are present. The Company has
established a policy to at least annually evaluate its tower assets and Current contract intangibles for impairment.

The Company records an impairment charge when the Company believes an investment in towers or related assets has been

impaired, such that future undiscounted cash flows would not recover the then current carrying value of the investment in the tower
and related intangible. If the future undiscounted cash flows are lower than the carrying value of the investment in the tower and

F-10

related intangible, the Company calculates future discounted cash flows and compares those amounts to the carrying value. The
Company records an impairment charge for any amounts lower than the carrying value. Estimates and assumptions inherent in the
impairment evaluation include, but are not limited to, general market and economic conditions, historical operating results, geographic
location, lease-up potential and expected timing of lease-up. In addition, the Company makes certain assumptions in determining an
asset’s fair value for the purpose of calculating the amount of an impairment charge.

The Company recognized impairment charges of $30.2 million, $94.8 million, and $23.8 million for the years ended December

31, 2016, 2015 and 2014, respectively. Refer to Note 3 for further detail of these amounts.

Fair Value Measurements

The Company determines the fair market values of its financial instruments based on the fair value hierarchy, which requires an

entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The
following three levels of inputs may be used to measure fair value:

Level 1

Level 2

Level 3

Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the
measurement date.

Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in
markets that are not active; or other inputs that are observable or can be corroborated by observable market data for
substantially the full term of the assets or liabilities.

Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the
assets or liabilities.

Revenue Recognition

Revenue from site leasing is recorded monthly and recognized on a straight-line basis over the current term of the related lease

agreements, which are generally five to ten years. Receivables recorded related to the straight-lining of site leases are reflected in other
assets on the Consolidated Balance Sheets. Rental amounts received in advance are recorded as deferred revenue on the Consolidated
Balance Sheets.

Site development projects in which the Company performs consulting services include contracts on a time and materials basis or

a fixed price basis. Time and materials based contracts are billed at contractual rates and revenue is recognized as the services are
rendered. For those site development contracts in which the Company performs work on a fixed price basis, site development billing
(and revenue recognition) is based on the completion of agreed upon phases of the project on a per site basis. Upon the completion of
each phase on a per site basis, the Company recognizes the revenue related to that phase. Site development projects generally take
from 3 to 12 months to complete. Amounts billed in advance (collected or uncollected) are recorded as deferred revenue on the
Company’s Consolidated Balance Sheets.

Revenue from construction projects is recognized on the percentage-of-completion method of accounting, determined by the
percentage of cost incurred to date compared to management’s estimated total cost for each contract. This method is used because
management considers total cost to be the best available measure of progress on the contracts. These amounts are based on estimates,
and the uncertainty inherent in the estimates initially is reduced as work on the contracts nears completion. The asset “costs and
estimated earnings in excess of billings on uncompleted contracts” represents costs incurred and revenues recognized in exces s of
amounts billed. The liability “billings in excess of costs and estimated earnings on uncompleted contracts,” included within other
current liabilities on the Company’s Consolidated Balance Sheets, represents billings in excess of costs incurred and revenue s
recognized. Provisions for estimated losses on uncompleted contracts are made in the period in which such losses are determined to be
probable.

Allowance for Doubtful Accounts

The Company performs periodic credit evaluations of its customers. The Company monitors collections and payments from its
customers and maintains a provision for estimated credit losses based upon historical experience, specific customer collection issues
identified, and past due balances as determined based on contractual terms. Interest is charged on outstanding receivables from
customers on a case by case basis in accordance with the terms of the respective contracts or agreements with those customers.
Amounts determined to be uncollectible are written off against the allowance for doubtful accounts in the period in which
uncollectibility is determined to be probable.

On June 20, 2016, Oi, S.A. (“Oi”), the Company’s largest customer in Brazil, filed a petition for judicial reorganization in
Brazil. Prior to the filing of the reorganization petition, Oi was current in all payment obligations to the Company. These obligations
related to periods ending on or before April 30, 2016. As a result of the relief provisions available in a judicial reorganization
proceeding, obligations of Oi to the Company arising from the periods from May 1, 2016 to June 20, 2016 remain unpaid. Due to the
uncertainty surrounding the recoverability of amounts owed by Oi relating to services provided prior to the date of Oi’s petition, the
Company has recorded a $16.5 million bad debt provision (the “Oi reserve”) which covers amounts owed or potentially owed by Oi as
of the filing date. Under Brazilian law governing judicial reorganizations, the contracts governing post-petition obligations such as
tower rents remain unchanged, and debtors do not have the ability to reject or terminate the contracts other than pursuant to their
original terms. Since the filing, the Company has received all rental payments due in connection with obligations of Oi accruing post-
petition. The Oi reserve has been recorded in Selling, general, and administrative expense on the consolidated statement of operations.

Cost of Revenue

Cost of site leasing revenue includes ground lease rent, property taxes, amortization of deferred lease costs, maintenance and

other tower operating expenses. All ground lease rental obligations due to be paid out over the lease term, including fixed escalations,
are recorded on a straight-line basis over the minimum lease term. Liabilities recorded related to the straight-lining of ground leases
are reflected in other long-term liabilities on the Consolidated Balance Sheets. Cost of site development revenue includes the cost of
materials, salaries and labor costs, including payroll taxes, subcontract labor, vehicle expense and other costs directly and indirectly
related to the projects. All costs related to site development projects are recognized as incurred.

Income Taxes

The Company recognizes deferred tax assets and liabilities for the estimated future tax consequences attributable to differences

between the financial reporting and tax bases of existing assets and liabilities. Deferred tax assets and liabilities are measured using
tax rates in effect for the year in which the temporary differences are expected to reverse. A valuation allowance is recorded to reduce
the carrying amounts of deferred tax assets if it is "more-likely-than-not" that those assets will not be realized. The Company
considers many factors when assessing the likelihood of future realization, including the Company's recent cumulative earnings
experience by taxing jurisdiction, expectations of future taxable income, prudent and feasible tax planning strategies that are available,
the carryforward periods available to the Company for tax reporting purposes and other relevant factors.

The Company began operating as a REIT for federal income tax purposes effective January 1, 2016. As a REIT, the Company
generally is not subject to corporate level federal income tax on taxable income it distributes to its stockholders as long as it meets the
organizational and operational requirements under the REIT rules. However, certain subsidiaries have made an election with the IRS
to be treated as a taxable REIT subsidiary (“TRS”) in conjunction with the Company’s REIT election. The TRS elections permit SBA
to engage in certain business activities in which the REIT may not engage directly, so long as these activities are conducted in entities
that elect to be treated as TRSs under the Internal Revenue Code.  A TRS is subject to federal and state income taxes on the income
from these activities. Additionally, the Company has included in TRSs our tower operations in most foreign jurisdictions; however,
the REIT holds selected tower assets in Puerto Rico and USVI. Those operations will continue to be subject to foreign taxes in the
jurisdiction in which such assets and operations are located regardless of whether they are included in a TRS.

For the tax year ended December 31, 2016, the Company will file separate federal tax returns for the REIT and TRS. The REIT
had taxable income and utilized net operating losses (“NOLs”) to offset its distribution requirement. The TRS generated a NOL which
will be carried forward to use in future years. Prior to the REIT conversion in 2016, the Company filed consolidated returns and had
taxable income for the years ended December 31, 2015 and 2014 and utilized NOL carry-forwards. These NOL carry-forwards are
retained by the REIT. The NOLs generated by the TRS in the current year are fully reserved by a valuation allowance.

F-12

The Company records a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be
taken in a tax return. The Company has not identified any tax exposures that require a reserve. To the extent that the Company records
unrecognized tax exposures, any related interest and penalties will be recognized as interest expense in the Company’s Consolidated
Statements of Operations.

The Company does not calculate U.S. taxes on undistributed earnings of foreign subsidiaries because substantially all such

earnings are expected to be reinvested indefinitely.

Stock-Based Compensation

The Company measures and recognizes compensation expense for all share-based payment awards made to employees and
directors, including stock options, restricted stock units and employee stock purchases under employee stock purchase plans. The
Company records compensation expense, for stock options and restricted stock units on a straight-line basis over the vesting period.
Compensation expense for employee stock options is based on the estimated fair value of the options on the date of the grant using the
Black-Scholes option-pricing model. Any stock options granted to non-employees would be valued using the Black-Scholes option-
pricing model based on the market price of the underlying common stock on the “valuation date,” which for options to non-employees
is the vesting date. Expense related to options granted to non-employees would be recognized on a straight-line basis over the shorter
of the period over which services are to be received or the vesting period. Compensation expense for restricted stock units is based on
the fair market value of the units awarded at the date of the grant.

In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which the

Company adopted as of January 1, 2016. The standard simplifies several aspects of the accounting for shared-based payment
transactions including accounting for income taxes, forfeitures, statutory tax withholding requirements, classification of awards as
either equity or a liability, and classification on the Consolidated Statement of Cash Flows. The financial statement impact of adopting
this standard was not material for all periods presented.

Asset Retirement Obligations

The Company has entered into ground leases for the land underlying the majority of the Company’s towers. A majority of these

leases require the Company to restore land interests to their original condition upon termination of the ground lease.

The Company recognizes asset retirement obligations in the period in which they are incurred, if a reasonable estimate of a fair
value can be made, and accretes such liability through the obligation’s estimated settlement date. The associated asset retir ement costs
are capitalized as part of the carrying amount of the related tower fixed assets, and over time, the liability is accreted to its present
value each period and the capitalized cost is depreciated over the estimated useful life of the tower.

The asset retirement obligation is included in other long-term liabilities on the Consolidated Balance Sheets. Upon settlement of
the obligations, any difference between the cost to retire an asset and the recorded liability is recorded in the Consolidated Statements
of Operations as a gain or loss. In determining the measurement of the asset retirement obligations, the Company considered the
nature and scope of the contractual restoration obligations contained in the Company’s third party ground leases, the historical
retirement experience as an indicator of future restoration probabilities, intent in renewing existing ground leases through lease
termination dates, current and future value and timing of estimated restoration costs and the credit adjusted risk-free rate used to
discount future obligations.

The following summarizes the activity of the asset retirement obligation liability:

Comprehensive Income (Loss)

Comprehensive income (loss) is defined as the change in equity (net assets) of a business enterprise during a period from

transactions and other events and circumstances from non-owner sources, and is comprised of net income (loss) and other foreign
currency adjustments.

Foreign Currency Translation

The functional currency for the Company’s Central American subsidiaries is the U.S. dollar. Monetary assets and liabilities of
such subsidiaries which are not denominated in U.S. dollars are remeasured at exchange rates in effect at the balance sheet date, and
revenues and expenses are remeasured at monthly average rates prevailing during the year. Unrealized translation gains and losses are
reported as other income/expense in the Consolidated Statement of Operations.

All assets and liabilities of foreign subsidiaries that do not utilize the U.S. dollar as its functional currency are translated at
period-end rates of exchange, while revenues and expenses are translated at monthly average rates of exchange prevailing during the
year. Unrealized translation gains and losses are reported as foreign currency translation adjustments through accumulated other
comprehensive loss in shareholders’ deficit.

Business Combinations

The Company accounts for business combinations under the acquisition method of accounting. The assets and liabilities
acquired are recorded at fair market value at the date of each acquisition and the results of operations of the acquired assets are
included with those of the Company from the dates of the respective acquisitions. The Company continues to evaluate all acquisitions
for a period not to exceed one year after the applicable closing date of each transaction to determine whether any additional
adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities assumed as a result of
information available at the acquisition date. The intangible assets represent the value associated with the current leases at the
acquisition date (“Current contract intangibles”) and future tenant leases anticipated to be added to the towers (“Network location
intangibles”) and were calculated using the discounted values of the current or future expected cash flows. The intangible assets are
estimated to have a useful life consistent with the useful life of the related tower assets, which is typically 15 years.

In connection with certain acquisitions, the Company may agree to pay contingent consideration (or earnouts) in cash or stock if
the communication sites or businesses that are acquired meet or exceed certain performance targets over a period of one to three years
after they have been acquired. The Company accrues for contingent consideration in connection with acquisitions at fair value as of
the date of the acquisition. All subsequent changes in fair value of contingent consideration payable in cash are recorded through
Consolidated Statements of Operations.

In September 2015, the FASB issued ASU 2015-16 Business Combinations. The standard requires that the acquirer (1)
recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the
adjustment amounts are determined, (2) record, in the same period’s financial statements, the effect on earnings of changes in
depreciation, amortization, or other income effects, as a result of the change to the provisional amounts, calculated as if the accounting
had been completed at the acquisition date, and (3) to present separately on the face of the income statement or disclose in the notes
the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods
if the adjustment to the provisional amounts had been recognized as of the acquisition date. The Company adopted this standard
prospectively effective January 1, 2016. The financial statement impact of adopting this standard was not material for any period
presented.

Cash Flows

In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments, which is intended

to decrease the diversity in practice in how certain cash receipts and cash payments are presented in the Consolidated Statement of
Cash Flows. The standard requires that (1) cash payments for debt prepayment or debt extinguishment costs be classified as cash
outflows for financing activities, (2) contingent consideration payments made soon after the acquisition date of a business combination
be classified as cash outflows for investing activities, and (3) contingent consideration payments not made soon after the acquisition
date of a business combination be separated with cash payments up to the amount of the contingent consideration at the acquisition
date be classified as financing activities and any excess be classified as operating activities. The Company adopted the standard
retrospectively effective January 1, 2016. The financial statement impact of adopting this standard was not material for any period
presented.

F-14

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows. The standard requires cash and cash equivalent

balances to include restricted cash equivalents. The Company adopted this standard as of January 1, 2016. Prior year periods have
been adjusted to conform to the current year presentation.

Intercompany Loans

On November 25, 2014, two wholly owned subsidiaries of the Company, Brazil Shareholder I, LLC, a Florida limited liability

company, and SBA Torres Brasil, Limitada, a limitada existing under the laws of the Republic of Brazil, entered into an intercompany
loan agreement where from time to time the entities may agree to lend/borrow amounts up to $750.0 million. As of December 31,
2016, the outstanding balance under this agreement was $433.3 million.

In accordance with ASC 830, the Company remeasures foreign denominated intercompany loans with the corresponding change

in the balance being recorded in Other income (expenses), net in the Consolidated Statements of Operations as settlement is
anticipated or planned in the foreseeable future. For the years ended December 31, 2016, 2015, and 2014, the Company recorded a
$90.0 million gain, a $178.9 million loss, and a $23.0 million loss, respectively, on the remeasurement of intercompany loans due to
changes in foreign exchange rates.

Recent Accounting Pronouncements Not Yet Adopted

In May 2014, the FASB released an updated standard regarding the recognition of revenue from contracts with customers,

exclusive of those contracts within lease accounting. The core principle of the standard is that an entity should recognize revenue to
depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects
to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (1)
identify the contracts with the customer; (2) identify the performance obligations in the contract; (3) determine the contract price; (4)
allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the entity satisfies
a performance obligation. This standard is effective in the first quarter of 2018. Early adoption is permitted but not before the first
quarter of 2017. This standard is required to be applied retrospectively to each prior reporting period presented or with the cumulative
effect being recognized at the date of initial application. The Company is evaluating the standard and does not expect a material
financial statement impact upon adoption since the standard only affects our site development segment which represents
approximately 6% of our total revenues.

In February 2016, the FASB issued ASU 2016-02, Leases. The standard requires lessees to recognize a right-of-use asset and a

lease liability, initially measured at the present value of the lease payments for all leases with a term greater than 12 months. The
accounting for lessors remains largely unchanged from existing guidance. This standard is effective for annual and interim periods
beginning after December 15, 2018 and requires a modified retrospective transition approach for all leases existing at, or entered into
after, the beginning of the earliest comparative period presented. Early adoption is permitted. The Company has established a cross
functional project plan to assess the impact of the standard, expects this guidance to have a material impact on its consolidated balance
sheet due to the addition of right-of-use assets and lease liabilities for all leases with a term greater than 12 months, and continues to
assess additional impacts to its consolidated financial statements, including the consolidated statement of operations.

In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business. The standard provides guidance to

help entities determine whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The standard
is effective for annual and interim periods beginning after December 15, 2018 and early adoption is permitted. The standard is
required to be applied prospectively. The Company is evaluating the standard, including the impact on its consolidated financial
statements.

FAIR VALUE MEASUREMENTS

Items Measured at Fair Value on a Recurring Basis— The Company’s earnout liabilities related to acquisitions are measured

at fair value on a recurring basis using Level 3 inputs and are recorded in Accrued expenses in the accompanying Consolidated
Balance Sheets. Changes in estimate are recorded in Acquisition related adjustments and expenses in the accompanying Consolidated
Statement of Operations. The Company determines the fair value of acquisition-related earnouts (contingent consideration) and any
subsequent changes in fair value using a discounted probability-weighted approach using Level 3 inputs. Level 3 valuations rely on
unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability.
The fair value of the earnouts is reviewed quarterly and is based on the payments the Company expects to make based on historical
internal observations related to the anticipated performance of the underlying assets. The Company’s estimate of the fair value of its
obligation contained in various acquisitions was $4.1 million and $7.2 million as of December 31, 2016 and 2015, respectively. The

F-15

maximum potential obligation related to the performance targets was $5.8 million and $10.2 million as of December 31, 2016 and
2015, respectively.

Items Measured at Fair Value on a Nonrecurring Basis— The Company’s long-lived assets, intangibles, and asset retirement
obligations are measured at fair value on a nonrecurring basis using Level 3 inputs. The Company considers many factors and makes
certain assumptions when making this assessment, including but not limited to: general market and economic conditions, historical
operating results, geographic location, lease-up potential and expected timing of lease-up. The fair value of the long-lived assets,
intangibles, and asset retirement obligations is calculated using a discounted cash flow model.

Asset impairment and decommission costs for all periods presented and the related impaired assets primarily relate to the
Company’s site leasing operating segment. The following summarizes the activity of asset impairment and decommission costs (in
thousands):

Asset impairment (1)
Impairment of fiber assets (2)
Gain on sale of fiber assets (2)
Write-off of carrying value of decommissioned towers

Represents impairment charges resulting from the Company’s analysis that the future cash flows from certain towers would not
recover the carrying value of the investment in those towers.
The impairment review of the fiber assets acquired in the 2012 Mobilitie transaction was triggered by a strategic decision made
by the Company in 2015. The gain in 2016 related to the sale of these fiber assets.

Fair Value of Financial Instruments— The carrying values of cash and cash equivalents, accounts receivable, restricted cash,
accounts payable, and short-term investments approximate their estimated fair values due to the short maturity of these instruments.
Short-term investments consisted of $0.5 million in certificate of deposits as of December 31, 2015, and $0.2 million in Treasury
securities as of December 31, 2016 and 2015. The Company’s estimate of the fair value of its held-to-maturity investments in treasury
and corporate bonds, including current portion, are based primarily upon Level 1 reported market values. As of December 31, 2016,
the carrying value and fair value of the long-term investments, including current portion, were $0.7 million. As of December 31, 2015,
the carrying value and fair value of the long-term investments, including current portion, was $0.8 million and $0.9 million,
respectively. These amounts are recorded in Other Assets in the accompanying Consolidated Balance Sheets.

The Company determines fair value of its debt instruments utilizing various Level 2 sources including quoted prices and
indicative quotes (non-binding quotes) from brokers that require judgment to interpret market information including implied credit
spreads for similar borrowings on recent trades or bid/ask prices. The fair value of the Revolving Credit Facility is considered to
approximate the carrying value because the interest payments are based on Eurodollar rates that reset every month. The Company does
not believe its credit risk has changed materially from the date the applicable Eurodollar Rate plus 137.5 to 200.0 basis points was set
for the Revolving Credit Facility. Refer to Note 12 for the fair values, principal balances, and carrying values of the Company’s debt
instruments.

Pursuant to the terms of the Tower Securities (see Note 12), the Company is required to establish a securitization escrow

account, held by the indenture trustee, into which all rents and other sums due on the towers that secure the Tower Securities are
directly deposited by the lessees. These restricted cash amounts are used to fund reserve accounts for the payment of (1) debt service
costs, (2) ground rents, real estate and personal property taxes and insurance premiums related to towers, (3) trustee and servicing
expenses, and (4) management fees. The restricted cash in the securitization escrow account in excess of required reserve balances is
subsequently released to the Borrowers (as defined in Note 12) monthly, provided that the Borrowers are in compliance with their debt
service coverage ratio and that no event of default has occurred. All monies held by the indenture trustee are classified as restricted
cash on the Company’s Consolidated Balance Sheets.

Payment and performance bonds relate primarily to collateral requirements for tower construction currently in process by the
Company. Cash is pledged as collateral related to surety bonds issued for the benefit of the Company or its affiliates in the ordinary
course of business and primarily related to the Company’s tower removal obligations. As of December 31, 2016, the Company had
$39.2 million in surety, payment and performance bonds for which it is only required to post $0.5 million in collateral. As of
December 31, 2015, the Company had $38.6 million in surety, payment and performance bonds for which it is only required to post
$0.7 million in collateral. The Company periodically evaluates the collateral posted for its bonds to ensure that it meets the minimum
requirements. As of December 31, 2016 and 2015, the Company had also pledged $2.5 million as collateral related to its workers
compensation policy.

In addition, the Company paid $14.1 million, $16.3 million, and $10.8 million for ground lease extensions during the years
ending 2016, 2015, and 2014, respectively. The Company recorded these amounts in prepaid rent on its Consolidated Balance
Sheet.

During the year ended December 31, 2016, the Company acquired 531 completed towers and related assets and liabilities for

$214.7 million in cash consisting of $72.8 million of property and equipment, $144.4 million of intangible assets, and $2.5 million of
working capital adjustments.

During the year ended December 31, 2015, the Company acquired 893 completed towers and related assets and liabilities for

$525.8 million in cash consisting of $176.3 million of property and equipment, $351.0 million of intangible assets, and $1.5 million of
working capital adjustments.

On March 31, 2014, the Company acquired 2,007 towers in Brazil from Oi S.A. for an aggregate purchase price of $673.9

million in cash. The fair value of the assets acquired and liabilities assumed relating to the Oi S.A. acquisition is summarized below

During the year ended December 31, 2014, in addition to the Oi S.A. acquisitions, the Company acquired 382 completed towers

and related assets and liabilities for $403.2 million in cash.

The Company evaluates all acquisitions after the applicable closing date of each transaction to determine whether any
additional adjustments are needed to the allocation of the purchase price paid for the assets acquired and liabilities assumed by major
balance sheet caption, as well as the separate recognition of intangible assets from goodwill if certain criteria are met.

F-18

The estimates of the fair value of the assets acquired and liabilities assumed at the date of an acquisition are subject to
adjustment during the measurement period (up to one year from the particular acquisition date). The primary areas of the preliminary
purchase price allocations that are not yet finalized relate to the fair value of certain tangible and intangible assets acquired and
liabilities assumed, including contingent consideration and any related tax impact. The fair values of these net assets acquired are
based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that
utilize customary valuation procedures and techniques. During the measurement period, the Company will adjust assets and/or
liabilities if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would
have resulted in a revised estimated value of those assets and/or liabilities as of that date. The effect of material measurement period
adjustments to the estimated fair values is recognized in the reporting period in which the adjustment amounts are determined and
calculated as if the adjustments had been completed at the acquisition date. The impact of all changes that do not qualify as
measurement period adjustments are included in current period earnings. If the actual results differ from the estimates and judgments
used in these fair values, the amounts recorded in the consolidated financial statements could be subject to a possible impairment of
the intangible assets, or require acceleration of the amortization expense of intangible assets in subsequent periods.

Subsequent to December 31, 2016, the Company acquired 42 towers and related assets for $17.3 million in cash.

Foreign Currency Forward Contract

On March 26, 2014, the Company settled  two foreign currency contracts entered into during the quarter with an aggregate
notional amount of R$1,525.0 million in order to hedge the purchase price of the Oi S.A. acquisition in Brazil, which closed on March
31, 2014. The Company realized a gain of $17.9 million related to these foreign currency forward contracts which is included in other
income in the accompanying Consolidated Statement of Operations and Net cash used in investing activities on the Consolidated
Statements of Cash Flows.

On September 29, 2014, the Company executed put and call option contracts settling on November 25, 2014 which created a

“costless collar” based on the cost to purchase $1.17 billion Brazilian Reais with US Dollars. The options were intended to limit
exposure to movements in the related exchange rates and were entered into in contemplation of the purchase of the Oi S.A. acquisition
that closed on December 1, 2014. These options created a floor price for the purchase of Brazilian Reais of 2.4 and a ceiling price of
2.5665. Since the closing price was within the floor and ceiling price, no gain or loss was realized.

The Company measures its foreign currency forward contracts, which are recorded in Prepaid and other current assets, at fair
value based on indicative prices in active markets (Level 2 inputs). These contracts do not qualify for hedge accounting and as such
any gains and losses are reflected within Other Income, net in the accompanying Consolidated Statement of Operations. As of
December 31, 2016, the Company does not have any pending forward contracts.

10. CONCENTRATION OF CREDIT RISK

The Company’s credit risks consist primarily of accounts receivable with national, regional, and local wireless service providers

and federal and state government agencies. The Company performs periodic credit evaluations of its customers’ financial condition
and provides allowances for doubtful accounts, as required, based upon factors surrounding the credit risk of specific customers,
historical trends, and other information. The Company generally does not require collateral.

The following is a list of significant customers (representing at least 10% of revenue for any period reported) and the percentage

of total revenue for the specified time periods derived from such customers:

On February 7, 2014, SBA Senior Finance II entered into a Second Amended and Restated Credit Agreement with several banks
and other financial institutions or entities from time to time parties to the Second Amended and Restated Credit Agreement to, among
other things, incur the 2014 Term Loan and amend certain terms of the existing senior credit agreement (as amended, the “Senior
Credit Agreement”).

Terms of the Senior Credit Agreement

The Senior Credit Agreement, as amended, requires SBA Senior Finance II to maintain specific financial ratios, including (1) a

ratio of Consolidated Total Debt to Annualized Borrower EBITDA not to exceed 6.5 times for any fiscal quarter, (2) a ratio of
Consolidated Total Debt and Net Hedge Exposure (calculated in accordance with the Senior Credit Agreement) to Annualized
Borrower EBITDA for the most recently ended fiscal quarter not to exceed 6.5 times for 30 consecutive days and (3) a ratio of
Annualized Borrower EBITDA to Annualized Cash Interest Expense (calculated in accordance with the Senior Credit Agreement) of
not less than 2.0 times for any fiscal quarter. The Senior Credit Agreement contains customary affirmative and negative covenants
that, among other things, limit the ability of SBA Senior Finance II and its subsidiaries to incur indebtedness, grant certain liens, make
certain investments, enter into sale leaseback transactions, merge or consolidate, make certain restricted payments, enter into
transactions with affiliates, and engage in certain asset dispositions, including a sale of all or substantially all of their property. As of
December 31, 2016, SBA Senior Finance II was in compliance with the financial covenants contained in the Senior Credit Agreement.
The Senior Credit Agreement is also subject to customary events of default. Pursuant to the Second Amended and Restated Guarantee
and Collateral Agreement, amounts borrowed under the Revolving Credit Facility, the Term Loans and certain hedging transactions
that may be entered into by SBA Senior Finance II or the Subsidiary Guarantors (as defined in the Senior Credit Agreement) with
lenders or their affiliates are secured by a first lien on the membership interests of SBA Telecommunications, LLC, SBA Senior
Finance, LLC and SBA Senior Finance II and on substantially all of the assets (other than leasehold, easement and fee interests in real
property) of SBA Senior Finance II and the Subsidiary Guarantors.

F-23

The Senior Credit Agreement, as amended, permits SBA Senior Finance II, without the consent of the other lenders, to request

that one or more lenders provide SBA Senior Finance II with increases in the Revolving Credit Facility or additional term loans
provided that after giving effect to the proposed increase in Revolving Credit Facility commitments or incremental term loans the ratio
of Consolidated Total Debt to Annualized Borrower EBITDA would not exceed 6.5 times. SBA Senior Finance II’s ability to request
such increases in the Revolving Credit Facility or additional term loans is subject to its compliance with customary conditions set forth
in the Senior Credit Agreement including compliance, on a pro forma basis, with the financial covenants and ratios set forth therein
and, with respect to any additional term loan, an increase in the margin on existing term loans to the extent required by the terms of
the Senior Credit Agreement. Upon SBA Senior Finance II’s request, each lender may decide, in its sole discretion, whether to
increase all or a portion of its Revolving Credit Facility commitment or whether to provide SBA Senior Finance II with additional
term loans and, if so, upon what terms.

Revolving Credit Facility under the Senior Credit Agreement

The Revolving Credit Facility is governed by the Senior Credit Agreement. The Revolving Credit Facility consists of a
revolving loan under which up to $1.0 billion aggregate principal amount may be borrowed, repaid and redrawn, based upon specific
financial ratios and subject to the satisfaction of other customary conditions to borrowing. Amounts borrowed under the Revolving
Credit Facility accrue interest, at SBA Senior Finance II’s election, at either (i) the Eurodollar Rate plus a margin that ranges from
137.5 basis points to 200.0 basis points or (ii) the Base Rate plus a margin that ranges from 37.5 basis points to 100.0 basis points, in
each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA, calculated in accordance with the Senior
Credit Agreement. In addition, SBA Senior Finance II is required to pay a commitment fee of 0.25% per annum on the amount of
unused commitment. If not earlier terminated by SBA Senior Finance II, the Revolving Credit Facility will terminate on, and SBA
Senior Finance II will repay all amounts outstanding on or before, February 5, 2020. The proceeds available under the Revolving
Credit Facility may be used for general corporate purposes. SBA Senior Finance II may, from time to time, borrow from and repay the
Revolving Credit Facility. Consequently, the amount outstanding under the Revolving Credit Facility at the end of a period may not be
reflective of the total amounts outstanding during such period.

During the year ended December 31, 2016, the Company borrowed $580.0 million and repaid $190.0 million of the outstanding

balance under the Revolving Credit Facility. As of December 31, 2016, $390.0 million was outstanding under the Revolving Credit
Facility.

Subsequent to December 31, 2016, the Company repaid $95.0 million of the outstanding balance under the Revolving Credit

Facility.

Term Loans under the Senior Credit Agreement

Repricing Amendment to the Senior Credit Agreement

On January 20, 2017, the Company amended its Senior Credit Agreement, primarily to reduce the stated rate of interest
applicable to its senior secured term loans.  As amended, our senior secured term loans accrue interest, at SBA Senior Finance II’s
election, at either the Base Rate plus 125 basis points (with a zero Base Rate floor) or the Eurodollar Rate plus 225 basis points (with a
zero Eurodollar Rate floor).

The 2011 Term Loan consisted of a senior secured term loan with an initial aggregate principal amount of $500.0 million with a
maturity date of June 30, 2018. The 2011 Term Loan accrued interest, at SBA Senior Finance II’s election, at either the Base Rate plus
a margin of 175 basis points (with a Base Rate floor of 2%) or Eurodollar Rate plus a margin of 275 basis points (with a Eurodollar
Rate floor of 1%). The 2011 Term Loan was issued at 99.75% of par value. The Company incurred deferred financing fees of $4.9
million associated with this transaction which were being amortized through the maturity date.

During the year ended December 31, 2013, the Company repaid $312.0 million on the 2011 Term Loan.

On February 7, 2014, the Company repaid the remaining $180.5 million outstanding principal balance of the 2011 Term Loan.

was to mature on May 9, 2017. The 2012-1 Term Loan accrued interest, at SBA Senior Finance II’s election, at either the Base Rate
plus a margin that ranged from 100 to 150 basis points or the Eurodollar Rate plus a margin that ranged from 200 to 250 basis points,
in each case based on the ratio of Consolidated Total Debt to Annualized Borrower EBITDA (calculated in accordance with the Senior
Credit Agreement). The 2012-1 Term Loan was issued at par. The Company incurred deferred financing fees of $2.7 million in
relation to this transaction which were being amortized through the maturity date.

During the year ended December 31, 2015, the Company repaid the entire outstanding balance of $172.5 million on the 2012-1

matures on March 24, 2021. Prior to the reduction in the term loan interest rates as discussed above, the 2014 Term Loan accrued

value. As of December 31, 2016, the 2014 Term Loan was accruing interest at 3.27% per annum. Principal payments on the 2014

Secured Tower Revenue Securities

Tower Revenue Securities Terms

The mortgage loan underlying the 2012-1C Tower Securities, 2013 Tower Securities, 2014 Tower Securities, 2015-1C Tower

Securities, and 2016-1C Tower Securities (together the “Tower Securities”) will be paid from the operating cash flows from the
aggregate 10,535 tower sites owned by the Borrowers. The mortgage loan is secured by (i) mortgages, deeds of trust, and deeds to
secure debt on a substantial portion of the tower sites, (ii) a security interest in the tower sites and substantially all of the Borrowers’
personal property and fixtures, (iii) the Borrowers’ rights under certain tenant leases, and (iv) all of the proceeds of the foregoing. For
each calendar month, SBA Network Management, Inc., an indirect subsidiary (“Network Management”), is entitled to receive a
management fee equal to 4.5% of the Borrowers’ operating revenues for the immediately preceding calendar month.

The Borrowers may prepay any of the mortgage loan components, in whole or in part, with no prepayment consideration,
(i) within twelve months (in the case of the component corresponding to the Secured Tower Revenue Securities Series 2012-1C,
Secured Tower Revenue Securities Series 2013-1C, Secured Tower Revenue Securities Series 2013-1D, Secured Tower Revenue
Securities Series 2014-1C, Secured Tower Revenue Securities Series 2015-1C, and Secured Tower Revenue Securities Series 2016-
1C) or eighteen months (in the case of the components corresponding to the Secured Tower Revenue Securities Series 2013-2C and
Secured Tower Revenue Securities Series 2014-2C) of the anticipated repayment date of such mortgage loan component, (ii) with
proceeds received as a result of any condemnation or casualty of any tower owned by the Borrowers or (iii) during an amortization
period. In all other circumstances, the Borrowers may prepay the mortgage loan, in whole or in part, upon payment of the applicable
prepayment consideration. The prepayment consideration is determined based on the class of the Tower Securities to which the
prepaid mortgage loan component corresponds and consists of an amount equal to the excess, if any, of (1) the present value
associated with the portion of the principal balance being prepaid, calculated in accordance with the formula set forth in the mortgage
loan agreement, on the date of prepayment of all future installments of principal and interest required to be paid from the date of
prepayment to and including the first due date within twelve months (in the case of the component corresponding to the Secured
Tower Revenue Securities Series 2012-1C, Secured Tower Revenue Securities Series 2013-1C, Secured Tower Revenue Securities
Series 2013-1D, Secured Tower Revenue Securities Series 2014-1C, Secured Tower Revenue Securities Series 2015-1C, and Secured
Tower Revenue Securities Series 2016-1C) or eighteen months (in the case of the components corresponding to the Secured Tower
Revenue Securities Series 2013-2C and Secured Tower Revenue Securities Series 2014-2C) of the anticipated repayment date of such
mortgage loan component over (2) that portion of the principal balance of such class prepaid on the date of such prepayment.

To the extent that the mortgage loan components corresponding to the Tower Securities are not fully repaid by their respective

anticipated repayment dates, the interest rate of each such component will increase by the greater of (i) 5% and (ii) the amount, if any,
by which the sum of (x) the ten-year U.S. treasury rate plus (y) the credit-based spread for such component (as set forth in the
mortgage loan agreement) plus (z) 5%, exceeds the original interest rate for such component.

Pursuant to the terms of the Tower Securities, all rents and other sums due on any of the towers owned by the Borrowers are

directly deposited by the lessees into a controlled deposit account and are held by the indenture trustee. The monies held by the
indenture trustee after the release date are classified as short-term restricted cash on the Consolidated Balance Sheets (see Note 4).
However, if the Debt Service Coverage Ratio, defined as the net cash flow (as defined in the mortgage loan agreement) divided by the
amount of interest on the mortgage loan, servicing fees and trustee fees that the Borrowers are required to pay over the succeeding
twelve months, as of the end of any calendar quarter, falls to 1.30x or lower, then all cash flow in excess of amounts required to make
debt service payments, to fund required reserves, to pay management fees and budgeted operating expenses and to make other
payments required under the loan documents, referred to as “excess cash flow,” will be deposited into a reserve account instead of
being released to the Borrowers. The funds in the reserve account will not be released to the Borrowers unless the Debt Service
Coverage Ratio exceeds 1.30x for two consecutive calendar quarters. If the Debt Service Coverage Ratio falls below 1.15x as of the
end of any calendar quarter, then an “amortization period” will commence and all funds on deposit in the reserve account will be
applied to prepay the mortgage loan until such time that the Debt Service Coverage Ratio exceeds 1.15x for a calendar quarter. In
addition, if any of the Tower Securities are not fully repaid by their respective anticipated repayment dates, the cash flow from the
towers owned by the Borrowers will be trapped by the trustee for the Tower Securities and applied first to repay the interest, at the
original interest rates, on the mortgage loan components underlying the Tower Securities, second to fund all reserve accounts and
operating expenses associated with those towers, third to pay the management fees due to Network Management, fourth to repay
principal of the Tower Securities and fifth to repay the additional interest discussed above. Furthermore, the advance rents reserve
requirement states that the Borrowers are required to maintain an advance rents reserve at any time the monthly tenant Debt Service
Coverage Ratio is equal to or less than 2:1 and for two calendar months after such coverage ratio again exceeds 2:1. The mortgage
loan agreement, as amended, also includes covenants customary for mortgage loans subject to rated securitizations. Among other
things, the Borrowers are prohibited from incurring other indebtedness for borrowed money or further encumbering their assets. As of
December 31, 2016, the Borrowers met the required Debt Service Coverage Ratio as set forth in the mortgage loan agreement and
were in compliance with all other covenants as set forth in the agreement.

F-26

2010 Tower Securities

On April 16, 2010, the Company, through a New York common law trust (the “Trust”), issued $680.0 million of 2010-1C

Tower Securities (the “2010-1C Tower Securities”) and $550.0 million of 2010-2C Tower Securities (the “2010-2C Tower
Securities”) (together the “2010 Tower Securities”). The 2010-1C Tower Securities had an annual interest rate of 4.254%, and the
2010-2C Tower Securities had an annual interest rate of 5.101%. The anticipated repayment date and the final maturity date for the
2010–1C Tower Securities were April 15, 2015 and April 16, 2040, respectively. The anticipated repayment date and the final
maturity date for the 2010–2C Tower Securities were April 11, 2017 and April 9, 2042, respectively. The sole asset of the Trust
consists of a non-recourse mortgage loan made in favor of those entities that are borrowers on the mortgage loan (“the Borrowers”).
The Company incurred deferred financing fees of $8.1 million in relation to this transaction which were being amortized through the
anticipated repayment date of each of the 2010 Tower Securities.

On October 15, 2014, the Company repaid in full the 2010-1C Tower Securities with proceeds from the 2014 Tower Securities

(defined below). In connection with the prepayment, the Company expensed $1.1 million of net deferred financing fees.

On July 15, 2016, the Company repaid in full the 2010-2C Tower Securities with proceeds from the 2016-1C Tower Securities.

Additionally, the Company expensed $1.0 million of deferred financing fees related to the redemption of the 2010-2C Tower
Securities, which are reflected in loss from extinguishment of debt on the Consolidated Statement of Operations.

2012-1C Tower Securities

On August 9, 2012, the Company, through the Trust, issued $610.0 million of Secured Tower Revenue Securities Series 2012-

14. STOCK-BASED COMPENSATION

The Company has two equity participation plans (the 2001 Equity Participation Plan and the 2010 Performance and Equity

Incentive Plan, the “2010 Plan”) whereby options (both non-qualified and incentive stock options), restricted stock units, stock
appreciation rights, and other equity and performance based instruments may be granted to directors, employees, and consultants. The
options and restricted stock units generally vest from the date of grant on a straight-line basis over the vesting term and generally have
a seven-year or a ten-year contractual life.

Upon the adoption of the 2010 Plan by the Company’s shareholders on May 6, 2010, the 2001 Equity Participation Plan was
terminated and the Company is no longer eligible to issue shares pursuant to that plan. The 2010 Plan provides for the issuance of a
maximum of 15.0 million shares of the Company’s Class A common stock, of which 8.8 million shares remain available for future
issuance as of December 31, 2016. However, the aggregate number of shares that may be issued pursuant to restricted stock awards,
restricted stock unit awards, stock bonus awards, performance awards, other stock-based awards, or other awards granted under the
2010 Plan will not exceed 7.5 million shares, of which 6.8 million shares remain available for future issuance as of December 31,
2016.

Stock Options

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the

date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The Company uses a
combination of historical data and historical volatility to establish the expected volatility. Historical data is used to estimate the
expected option life. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated life of
the option. The following assumptions were used to estimate the fair value of options granted using the Black-Scholes option-pricing
model:

Risk free interest rate
Dividend yield
Expected volatility
Expected lives

INCOME TAXES

As discussed in Note 2, the Company began operating in compliance with REIT requirements for federal income tax purposes

effective January 1, 2016.  As a REIT, the Company must distribute at least 90 percent of its taxable income (including dividends paid
to it by its TRSs) except to the extent offset by NOLs.  In addition, the Company must meet a number of other organizational and
operational requirements. It is management's intention to adhere to these requirements and maintain the Company's REIT status. Most
states where SBA operates conform to the federal rules recognizing REITs. Certain subsidiaries have made an election with the
Company to be treated as TRSs in conjunction with the Company's REIT election; the TRS elections permit SBA to engage in certain
business activities in which the REIT may not engage directly.  A TRS is subject to federal and state income taxes on the income from
these activities. A provision for taxes of the TRSs and of foreign branches of the REIT are included in its consolidated financial
statements.

A deferred tax asset is reduced by a valuation allowance if based on the weight of all available evidence, it is more likely than
not (a likelihood of more than 50%) that the value of such assets will not be realized. The valuation allowance should be sufficient to
reduce the deferred tax asset to the amount that is more likely than not to be realized. The determination of whether a deferred tax
asset is realizable is based on weighting all available evidence, including both positive and negative evidence. The realization of
deferred tax assets, including carryforwards and deductible temporary differences, depends upon the existence of sufficient taxable
income of the same character during the carryback or carryforward period. All sources of taxable income available to realize the
deferred tax asset, including the future reversal of existing temporary differences, future taxable income exclusive of reversing
temporary differences and carryforwards, taxable income in carryback years and tax-planning strategies, should be considered.

F-35

The Company has recorded a valuation allowance for the majority of its deferred tax assets as management believes that it is not

“more-likely-than-not” that the Company will generate sufficient taxable income in future periods to recognize the assets. Valuation
allowances of $70.2 million and $292.9 million were being carried to offset net deferred income tax assets as of December 31, 2016
and 2015, respectively. The net change in the valuation allowance for the years ended December 31, 2016 and 2015 was $(222.6)
million and $25.6 million, respectively. As a result of the REIT conversion, the Company has reversed net deferred tax assets and the
related valuation allowance of the subsidiaries included in the REIT in the amount of $205.3 million.

The Company has available at December 31, 2016, a federal NOL carry-forward of approximately $1.2 billion. These NOL

carry-forwards will expire between 2021 and 2036. As of December 31, 2016, $1.1 billion of the federal NOLs are attributes of the
REIT. The Company may use these NOLs to offset its REIT taxable income, and thus any required distributions to shareholders may
be reduced or eliminated until such time as the NOLs have been fully utilized. The Internal Revenue Code places limitations upon the
future availability of NOLs based upon changes in the equity of the Company. If these occur, the ability of the Company to offset
future income with existing NOLs may be limited. In addition, the Company has available at December 31, 2016, a foreign NOL
carry-forward of $66.6 million and a net state operating tax loss carry-forward of approximately $502.0 million. These net operating
tax loss carry-forwards begin to expire in 2017.

The U.S. tax losses generated in tax years 1999 through 2013 remain subject to adjustment, and tax years 2013 through 2016 are

open to examination by the major jurisdictions in which the Company operates.

The Company does not expect to remit earnings from its foreign subsidiaries. Undistributed earnings of the Company’s foreign

subsidiaries amounted to approximately $92.8 million at December 31, 2016. $60.3 million of these earnings are considered to be
permanently reinvested; accordingly, no U.S. Federal and state income taxes have been provided thereon. It is not practicable to
compute the potential deferred tax liability associated with these undistributed foreign earnings. Upon distribution of those earnings
in the form of dividends or otherwise, the Company could be subject to both U.S. income taxes (subject to an adjustment for foreign
tax credits) and withholding taxes payable to various foreign countries.

As discussed in Note 2, the Company adopted ASU 2016-09 during 2016.  Prior to 2016, tax benefit was recognized in equity

related to equity-based compensation as our excess tax benefits did not reduce taxes payable.  During 2016, we recognized $27.3
million of excess tax deductions in our income tax provision that are ultimately offset with a valuation allowance at the TRS for no net
benefit.

16. COMMITMENTS AND CONTINGENCIES

Leases

The Company is obligated under various non-cancelable operating leases for land, office space, equipment and site leases that

expire at various times through December 2152. In addition, the Company is obligated under various non-cancelable capital leases for
vehicles that expire at various times through August 2020.

The annual minimum lease payments under non-cancelable operating and capital leases for the next five years as of December

31, 2016 are as follows (in thousands):

Future minimum rental payments under noncancelable ground leases include payments for certain renewal periods at the
Company’s option because failure to renew could result in a loss of the applicable tower and related revenue from tenant leases,

F-36

thereby making it reasonably assured that the Company will renew the lease. The majority of operating leases provide for renewal at
varying escalations. Fixed rate escalations have been included in the table disclosed above.

Rent expense for operating leases was $253.7 million, $239.8 million and $223.4 million for the years ended December 31,
2016, 2015 and 2014, respectively. In addition, certain of the Company’s leases include contingent rent provisions which provide for
the lessor to receive additional rent upon the attainment of certain tower operating results and/or lease-up. Contingent rent expense for
the years ended December 31, 2016, 2015 and 2014 was $25.0 million, $24.4 million and $23.3 million, respectively.

Tenant Leases

The annual minimum tower lease income to be received for tower space and antenna rental under non-cancelable operating

leases for the next five years as of December 31, 2016 are as follows:

The Company’s tenant leases provide for annual escalations and multiple renewal periods, at the tenant’s option. The tenant

rental payments disclosed in the table above do not assume exercise of tenant renewal options, however, fixed rate escalations have
been included.

Litigation

The Company is involved in various claims, lawsuits and proceedings arising in the ordinary course of business. While there are

uncertainties inherent in the ultimate outcome of such matters and it is impossible to presently determine the ultimate costs that may
be incurred, management believes the resolution of such uncertainties and the incurrence of such costs will not have a material adverse
effect on the Company’s consolidated financial position, results of operations or liquidity.

Contingent Purchase Obligations

From time to time, the Company agrees to pay additional consideration (or earnouts) for acquisitions if the towers or businesses

that are acquired meet or exceed certain performance targets in the one to three years after they have been acquired. For the years
ended December 31, 2016, 2015, and 2014 certain earnings targets associated with the acquired towers were achieved, and therefore,
the Company paid in cash $5.7 million, $4.1 million, and $18.7 million, respectively. As of December 31, 2016, the Company’s
estimate of its potential obligation if the performance targets contained in various acquisition agreements were met was $4.1 million
which the Company recorded in accrued expenses. The maximum potential obligation related to the performance targets was $5.8
million and $10.2 million as of December 31, 2016 and 2015, respectively.

17. DEFINED CONTRIBUTION PLAN

The Company has a defined contribution profit sharing plan under Section 401(k) of the Internal Revenue Code that provides
for voluntary employee contributions up to the limitations set forth in Section 402(g) of the Internal Revenue Code. Employees have
the opportunity to participate following completion of three months of employment and must be 21 years of age. Employer matching
begins immediately upon the employee’s participation in the plan.

The Company makes a discretionary matching contribution of 75% of an employee’s contributions up to a maximum of $4,000

annually. Company matching contributions were approximately $2.0 million, $2.1 million and $2.0 million for the years ended
December 31, 2016, 2015 and 2014, respectively.

18. SEGMENT DATA

The Company operates principally in two business segments: site leasing and site development. The Company’s site leasing
business includes two reportable segments, domestic site leasing and international site leasing. The Company’s business segments are

F-37

strategic business units that offer different services. They are managed separately based on the fundamental differences in their
operations. The site leasing segment includes results of the managed and sublease businesses. The site development segment includes
the results of both consulting and construction related activities. The Company’s Chief Operating Decision Maker utilizes segment
operating profit and operating income as his two measures of segment profit in assessing performance and allocating resources at the
reportable segment level.

Basic and diluted net income (loss) per share is computed by dividing net income by the weighted average number of shares for

the period. Potentially dilutive instruments have been excluded from the computation of diluted loss per share as their impact would
have been anti-dilutive.

Because net income (loss) per share amounts are calculated using the weighted average number of common and dilutive

common shares outstanding during each quarter, the sum of the per share amounts for the four quarters may not equal the total loss per
share amounts for the year.

20.

EARNINGS PER SHARE

Basic earnings per share was computed by dividing net income from continuing operations attributable to common shareholders

by the weighted-average number of shares of Common Stock outstanding for each respective period. Diluted earnings per share was
calculated by dividing net income from continuing operations attributable to common shareholders by the weighted-average number

F-39

of shares of Common Stock outstanding and any dilutive Common Stock equivalents, including unvested restricted stock and shares
issuable upon exercise of stock options as determined under the “If-Converted” method and also Common Stock warrants as
determined under the “Treasury Stock” method.

The following table sets forth basic and diluted net income per common share for the years ended December 31, 2016, 2015,

and 2014 (in thousands, except per share data):

For the year ended December 31, 2016, the diluted weighted average number of common shares outstanding excluded an
additional 2.2 million shares issuable upon exercise of the Company’s stock options because the impact would be anti-dilutive.

For the year ended December 31, 2015, all potential common stock equivalents, including 3.8 million shares of stock options

outstanding and 0.3 million shares of restricted stock units outstanding, were excluded as the effect would be anti-dilutive.

For the year ended December 31, 2014, all potential common stock equivalents, including 3.3 million shares of stock options

outstanding and 0.3 million shares of restricted stock units outstanding, were excluded as the effect would be anti-dilutive.

SBA’s  Class  A Common Stock began trading on The NASDAQ National Market on June 16, 1999 when its initial  public offering 
commenced  and  is  currently  traded  on  the  NASDAQ  Global  Select  Market.  The  following  graph  shows  the  total  return  to  the 
shareholders of an investment in SBA’s Class A Common Stock as compared to (i) an investment in the NASDAQ Composite Index 
and (ii) an investment in a peer group made up of American Tower Corporation and Crown Castle International Corporation (the “Peer 
Group”), the comparable domestic public wireless tower companies. 

Total shareholder return is determined by dividing (i) the sum of (A) the cumulative amount of dividends for a given period (assuming 
dividend reinvestment) and (B) the change in share price between the beginning and end of the measurement period, by (ii) the share 
price at the beginning of the measurement period.

Required Disclosures Non-GAAP Financial Measures in Accordance with Regulation G 

SBA Communications Corporation (“SBA” or “we”) often makes disclosures of non-GAAP financial measures, such as (i) Tower Cash 
Flow and Tower Cash Flow Margin; (ii) Net Debt, Net Secured Debt, Leverage Ratio, and Secured Leverage Ratio (collectively, our 
“Non-GAAP Debt Measures”); and (iii) Funds from Operations (“FFO”), Adjusted Funds from Operations (“AFFO”), and AFFO per 
share.  We also provide certain financial metrics after eliminating the impact of changes in foreign currency exchange rates (collectively, 
our “Constant Currency Measures”). Following is a  reconciliation of these non-GAAP financial  measures to their  most comparable 
GAAP measures and the other information required by Regulation G.  An additional non-GAAP financial measure, Adjusted EBITDA, 
which is included in this annual report, is discussed and included in our Form 10-K which accompanies this annual report. 

We believe that Tower Cash Flow and Tower Cash Flow Margin are useful indicators of the performance of our site leasing operations.  

We  believe  that  Annualized  Adjusted  EBITDA  and  Adjusted  EBITDA  Margin  are  useful  to  investors  or  other  interested  parties  in 
evaluating our financial performance. Adjusted EBITDA is the primary measure used by management (1) to evaluate  the economic 
productivity of our operations and (2) for purposes of making decisions about allocating resources to, and assessing the performance of, 
our  operations.  Management  believes  that  Adjusted  EBITDA  helps  investors  or  other  interested  parties  meaningfully  evaluate  and 
compare the results of our operations (1) from period to period and (2) to our competitors, by excluding the impact of our capital structure 
(primarily  interest  charges  from  our  outstanding  debt)  and  asset  base  (primarily  depreciation,  amortization  and  accretion)  from  our 
financial results. Management also believes Adjusted EBITDA is frequently used by investors or other interested parties in the evaluation 
of REITs. In addition, Adjusted EBITDA is similar to the measure of current financial performance generally used in our debt covenant 
calculations. Adjusted EBITDA should be considered only as a supplement to net income computed in accordance with GAAP as a 
measure of our performance. 

We believe that our Non-GAAP Debt Measures provide investors a more complete understanding of our net debt and leverage position 
as they include the full principal amount of our debt which will be due at maturity, and, to the extent that such measures are calculated 
on Net Debt are net of our cash and cash equivalents. 

We believe that FFO,  AFFO  and AFFO per share,  which are metrics  used by our public company peers in the communication site 
industry, provide investors  useful indicators of  the  financial performance of our business and permit investors an additional tool to 
evaluate the performance of our business against those of our two principal competitors. On October 3, 2016, SBA’s Board authorized 
SBA to take the steps necessary to be subject to tax as a REIT commencing with the taxable year ending December 31, 2016. We believe 
that we are operating in a manner that complies with the REIT rules as of January 1, 2016. As a result, we have updated our definition 
of FFO. Under the revised definition, FFO no longer includes an adjustment to reflect our estimate of our cash taxes had we been a 
REIT. However, AFFO continues to exclude the non-cash portion of our reported tax provision. We refer to the prior definition as FFO, 
as previously defined. FFO, AFFO, and AFFO per share are also used to address questions we receive from analysts and investors who 
routinely assess our operating performance on the basis of these performance measures, which are considered industry standards. We 
believe that FFO helps investors or other interested parties meaningfully evaluate financial performance by excluding the impact of our 
asset  base  (primarily  depreciation,  amortization  and  accretion).  We  believe  that  AFFO  and  AFFO  per  share  help  investors  or other 
interested parties  meaningfully evaluate  our financial  performance as they include (1) the impact of our capital  structure (primarily 
interest expense on our outstanding debt) and (2) sustaining capital expenditures and exclude the impact of our (1) asset base (primarily 
depreciation, amortization and accretion) and (2) certain non-cash items, including straight-lined revenues and expenses related to fixed 
escalations and rent free periods. GAAP requires rental revenues and expenses related to leases that contain specified rental increases 
over the life of the lease to be recognized evenly over the life of the lease. In accordance with GAAP, if payment terms call for fixed 
escalations, or rent free periods, the revenue or expense is recognized on a straight-lined basis over the fixed, non-cancelable term of 
the contract. We only use AFFO as a performance measure. AFFO should be considered only as a supplement to net income computed 
in accordance with GAAP as a measure of our performance and should not be considered as an alternative to cash flows from operations 
or as residual cash flow available for discretionary investment. We believe our definition of FFO is consistent with how that term is 
defined by the National Association of Real Estate Investment Trusts (“NAREIT”) and that our definition and use of AFFO and AFFO 
per share is consistent with those reported by the other communication site companies. 

We  believe  that  our  Constant  Currency  Measures  provide  management  and  investors  the  ability  to  evaluate  the  performance  of  the 
business without the impact of foreign exchange fluctuations.  

 
In addition, Tower Cash Flow, Adjusted EBITDA, and our Non-GAAP Debt Measures are components of the calculations used by our 
lenders  to  determine  compliance  with  certain  covenants  under  our  debt  instruments.  These  non-GAAP  financial  measures  are  not 
intended to be an alternative to any of the financial measures provided in our results of operations or our balance sheet as determined in 
accordance with GAAP. 

We also provide organic cash leasing revenue, an operational metric, which compares the results of towers owned in the prior-year 
period to results from the current period, excluding non-cash straight-line site leasing revenue, growth from acquisitions, new tower 
builds, and the  impacts of certain non-standard tower leasing revenue items, such as pass-through expenses  grossed up into leasing 
revenue, amortization of augmentation reimbursements and our managed and non-macro business.
