The Tower Asset

Section 1

Wireless Tower Basics

What is a tower?

›A vertical structure built on a parcel of land,

designed to accommodate multiple tenants

›Our tenants utilize many different technologies,

including telephony, mobile data, broadcast

television and radio

›Tenants lease vertical space on the tower and

portions of the land underneath for

their equipment

What is found at the tower site?

›Tower company typically owns or leases under

a long-term contract:

›Tower structure

›Ground interest (fee simple or lease)

›Tenant typically owns and operates:

›Equipment, including antenna arrays,

antenna, coaxial cables and base stations

›Equipment shelters

Types of Towers

Monopole

›100 - 200 feet

›Typical use: telephony

Lattice

›200 - 400 feet

›Also called self-support

›Typical use: telephony

Guyed

›200 - 2,000 feet

›Typical use: television and

radio broadcasting, paging

and telephony

Stealth

›Range in size

›Generally used to maintain

aesthetic quality of area

›Particularly useful in

areas with strict zoning

regulations

Typical Tower Components

1. Whip Antenna

›A stiff, monopole antenna, usually mounted vertically.

2. Antenna Array

›A platform (typically three sided) where tenants place equipment to provide

signal transmission and reception to a specific area. The number of antennas

necessary per array is determined based on a number of factors, including:

›the number of active subscribers;

›the volume and type of network usage by subscribers

(e.g., average minutes of use, voice versus data);

›the technology being used (e.g.: CDMA, GSM, LTE);

›the type of spectrum currently utilized by the tenant.

3. Port Holes

›Holes cut into the base and top of tower to allow cables

and wiring to pass through the tower structure, from the

base station to the antennas.

4. Panel / Antenna

›Tenant equipment which transmits a signal from the

tower to a mobile device or vice versa.

5. Microwave Dish

›A specific type of antenna, which is used in point-to-point radio, television and

data communications. Also commonly used by wireless carriers for backhaul.

Typical Tower Components (continued)

6. Coaxial Cabling (Fiber)

›Transmission lines that carry the signal received from the antenna to the base

station or vice versa.

7. Reinforcement Bars

›Threaded anchors which are used to reinforce towers to add additional

capacity to accommodate further tenants.

8. Shelters

›Buildings at sites used by our tenants to house communications,

radio and network equipment. Some shelters are designed to be stacked

on top of one another to conserve space at smaller sites.

9. Generator

›Gas or diesel powered generators provide emergency backup

power to keep tenant equipment operational during power outages.

AMT has also introduced Backup Power Solution to allow

multiple tenants to use a single generator.

10. Ground Space

›The area within a site where tenants

lease space from the tower company to place

their shelters and generators.

What is Spectrum?

›Spectrum airwaves are licensed to carriers who utilize the spectrum to transmit wireless signals

›The government typically regulates this spectrum and auctions it to wireless carriers for use

›Spectrum is measured in units of “hertz” or Hz

›The three main considerations in evaluating a carrier’s spectrum position include:

1. In which spectrum bands does the carrier hold licenses?

2. How much spectrum (bandwidth) does the carrier have?

3. What type of technology is the carrier deploying on that band of spectrum (i.e. CDMA, HSPA, LTE)?

Spectrum: radio frequency airwaves, needed to transmit analog signals, including wireless

communications signals

Spectrum Characteristics

›Propagation – radio transmits a signal by driving a current on an antenna; signal

propagates away from antenna as a wave at the speed of light

›Lower-frequency spectrum provides a larger coverage area and better in-building

penetration (“beach front” spectrum)

›Higher-frequency spectrum covers shorter distances (need significantly more cell sites to

get the same level of coverage)

›As spectrum usage increases the distance spectrum can propagate decreases

2.5GHz 1.9GHz 1.6GHz 700MHz

(Not to scale)

Radio Spectrum Signal

What is a Cell Site?

A cell site is an area within a carrier’s wireless network which is serviced by an

antenna array. Carriers commonly refer to these areas as “rings”.

›Can be located on a tower or alternative structures, such as

rooftops, water towers and church steeples

›One macro tower can support multiple carriers’ cell sites through collocation

Cell Site Network

Tower/antenna location Geographic area covered by antenna array

A carrier’s coverage area is dependent upon the

capacity of its equipment and the frequency of

the signal being transmitted.

Cell Site

Narrowing Cell Radius

Signal Strength Curve

As devices become more advanced, the increasing demand for high-bandwidth applications

and higher quality of service result in a narrower range at which signals can be transmitted. As

a result, carriers are investing in denser networks.

Network Design Evolution

therefore required to create

adequate coverage for

seamless data usage

›Smartphone penetration

Wide NarrowPopulation Coverage Area

Tower sites continue to be our customers’ preferred solution, as they provide the most

technologically efficient and cost-effective option for coverage and capacity requirements.

Wi-Fi vs. Licensed Spectrum

Licensed spectrum allows for exclusive use by licensees with consent of the Federal

Communications Commissions (FCC). Wi-Fi spectrum is unlicensed and it can be used

by any party.

›Disadvantages of using unlicensed Wi-Fi spectrum:

1. Limited Mobility: Unlicensed Wi-Fi spectrum is in the high frequency 2.4 GHz and 5 GHz

bands. This means it is unable to propagate far, requiring significantly more transition

locations to cover an area and limiting its geographic reach.

2. Congestion: Any Wi-Fi capable device is permitted to use unlicensed Wi-Fi spectrum and

as a result, WiFi networks often become congested.

3. Loss of Control: Carriers lose control of their subscribers’ user experience when utilizing

public, unlicensed spectrum.

4. Concentrated in Dense Urban Areas: Because unlicensed spectrum is high frequency and

unable to propagate long distances, it is used predominantly in dense urban areas where

mobility requirements are limited and access points are closer together.

The Morphology View

Morphology is a useful metric to segment tower locations, varying from dense urban

locations to rural locations

DAS and Rooftops Help Fill the Gaps

Indoor DAS

›Provides coverage in indoor

venues, such as malls, casinos

and conference centers

where signals from towers

are insufficient

›Neutral-host networks are

readily accessible to collocation

›AMT is the largest independent

provider of IDAS in the U.S.

Outdoor DAS

›Provides coverage in outdoor

venues, such as racetracks

and stadiums where wireless

usage levels tend to be

extremely concentrated

›Allows for multiple carriers to

leverage single installation

›AMT has partnered with

NASCAR and other venues to

install Outdooor DAS systems

Rooftops

›Predominantly located in dense

urban areas where towers

cannot be installed

›Used in combination with DAS

and Wi-Fi to provide coverage

to concentrated user base

›AMT has access to over 22,000

rooftops throughout the country

Indoor and Outdoor Distributed Antenna Systems (IDAS/ODAS) and Rooftop locations help to

provide coverage in areas where macro tower sites are not available.

Network Design of the Future

Heterogeneous Networks (HetNets)

Network deployments will consist of multiple layers—traditional macro cell towers

provide a blanket of coverage, while underneath this umbrella, a combination of

other technologies are deployed to increase network capacity, particularly in

dense urban areas.

›Macro sites will continue to provide wide area coverage for high mobility users and are the core of

wireless networks

›Multiple solutions including DAS, Rooftops, Wi-Fi and Small Cell networks will complement the coverage

provided by towers

U.S. Demand Drivers

Section 4

Carrier Lease / Build Decision(1)

›Significant economic incentive exists for carriers to choose a collocation model over building

their own site

›Significant time to market advantage from leasing space on an existing tower site

›Building a site may involve years of work to secure ground interests and zoning approvals

An Example

›Present value of carrier network build-out alternatives

›Carrier Build Scenario

›$225,000 construction cost, $1,250 monthly operating expenses with 3% annual escalator,

The rollout of 4G in the U.S. is expected to take the better part of a decade and is expected to

result in long-term, solid demand for communications towers.

VoLTE Adoption Requires More Towers

Voice service is currently delivered mainly over 2G and 3G networks while data is

transmitted using 4G/LTE networks. Carriers have now deployed or are deploying

“voice over LTE” or VoLTE to move voice transmission to 4G/LTE networks.

Higher spectral efficiency than

2G/3G for delivering voice

Allows 2G/3G spectrum to be

refarmed to LTE

Reduces opex of maintaining distinct

voice and data networks

Potential for higher quality calls

Simultaneous voice and data

possible (not available on CDMA-LTE

phones today)

Increased battery life for LTE-only

phones vs. dual-radio CDMA-LTE

phones

›Increased cellsite densification

compared to LTE data-only networks

•Example: Moving from a network

designed for data-only (i.e. no voice

support at all) to VoLTE on 700 MHz

spectrum could require ~20% more

cell sites

Benefits of VoLTE

Requirements for VoLTE

Why does VoLTE require network densification?

Voice delivered with quality of service requirements (QoS)

has more stringent capacity requirements than “pure-data”

(e.g. browsing) – this is much more pronounced on the typical

cell edge, where a data session can degrade to a point (but a

voice call can’t)

Data

Session:

VoLTE

Session:

Higher throughput, high

efficiency modulation

scheme used

Lower throughput, more

robust (but less efficient)

modulation scheme used

Capacity requirements for a voice call with some minimum QoS don’t

change whether close to cell site or at cell edge

Income tax provision (benefit); Other income (expense); Loss on retirement of long-term obligations; Interest expense; Interest income; Other

operating income (expense); Depreciation, amortization and accretion; and Stock-based compensation expense.

Adjusted EBITDA Margin: the percentage that results from dividing Adjusted EBITDA by total revenue.

Adjusted Funds From Operations, or AFFO: NAREIT Funds From Operations before (i) straight-line revenue and expense, (ii) stock-

based compensation expense, (iii) the non-cash portion of our tax provision, (iv) non-real estate related depreciation, amortization and

accretion, (v) amortization of deferred financing costs, capitalized interest, debt discounts and premiums and long-term deferred interest

charges, (vi) other income (expense), (vii) loss on retirement of long-term obligations, (viii) other operating income (expense), and

adjustments for (ix) unconsolidated affiliates, and (x) noncontrolling interest, less cash payments related to capital improvements and cash

payments related to corporate capital expenditures.

AFFO per Share: Adjusted Funds From Operations divided by the diluted weighted average common shares outstanding.

Churn: Revenue lost when a tenant cancels or does not renew its lease, and in limited circumstances, such as a tenant bankruptcy,

reductions in lease rates on existing leases.

Core Growth: (Rental and management revenue, Adjusted EBITDA, Gross Margin and Operating Profit) the increase or decrease,

expressed as a percentage, resulting from a comparison of financial results for a current period with corresponding financial results for the

corresponding period in a prior year, in each case, excluding the impact of straight-line revenue and expense recognition, foreign currency

exchange rate fluctuations and material one-time items.

NAREIT FFO: Net income before gains or losses from the sale or disposal of real estate, real estate related impairment charges, real estate

related depreciation, amortization and accretion and dividends declared on preferred stock, and including adjustments for (i) unconsolidated

affiliates and (ii) noncontrolling interest.

Operating Profit Margin: Operating profit divided by total revenue.

Organic Core Growth: (Rental and management revenue) the increase or decrease, expressed as a percentage, resulting from a comparison of financial

results for a current period with corresponding financial results for the corresponding period in a prior year, in each case, excluding the impact of straight-

line revenue and expense recognition, foreign currency exchange rate fluctuations, significant one-time items and revenue associated with new properties

that the Company has added to the portfolio since the beginning of the prior period.

Recurring Free Cash Flow: Adjusted EBITDA before straight-line revenue and expense plus interest income less interest expense, cash paid for income

taxes and non-discretionary capital expenditures (redevelopment, capital improvement and corporate capital expenditures).

Recurring Free Cash Flow per Share: Recurring Free Cash Flow divided by the diluted weighted average common shares outstanding.

Segment Gross Margin: segment revenue less segment operating expenses, excluding stock-based compensation expense recorded in costs of

operations; depreciation, amortization and accretion; selling, general, administrative and development expense; and other operating expenses.

International rental and management segment includes interest income, TV Azteca, net.

Segment Gross Margin Conversion Rate: the percentage that results from dividing the change in gross margin by the change in revenue.

Segment Operating Profit: Segment gross margin less segment selling, general, administrative and development expense attributable to the segment,

excluding stock-based compensation expense and corporate expenses. International rental and management segment includes interest income, TV

Azteca, net.

Pass-through Revenues: In several of our international markets we pass through certain operating expenses to our tenants, including in Latin America

where we primarily pass through ground rent expenses, and in India and South Africa, where we primarily pass through fuel costs. We record pass through

as revenue and a corresponding offsetting expense for these events.

Straight-line expenses: We calculate straight-line ground rent expense for our ground leases based on the fixed non-cancellable term of the underlying

ground lease plus all periods, if any, for which failure to renew the lease imposes an economic penalty to us such that renewal appears, at the inception of

the lease, to be reasonably assured. Certain of our tenant leases require us to exercise available renewal options pursuant to the underlying ground lease,

if the tenant exercises its renewal option. For towers with these types of tenant leases at the inception of the ground lease, we calculate our straight-line

ground rent over the term of the ground lease, including all renewal options required to fulfill the tenant lease obligation.

Straight-line revenues: We calculate straight-line rental revenues from our tenants based on the fixed escalation clauses present in non-cancellable

lease agreements, excluding those tied to the Consumer Price Index or other inflation-based indices, and other incentives present in lease agreements with

our tenants. We recognized revenues on a straight-line basis over the fixed, non-cancellable terms of the applicable leases.

Risk Factors

This presentation contains "forward-looking statements" concerning our goals, beliefs, expectations, strategies, objectives, plans,

future operating results and underlying assumptions, and other statements that are not necessarily based on historical

facts. Examples of these statements include, but are not limited to statements regarding our leverage range, our growth

expectations, including AFFO per share and our REIT distributions, and our expectations regarding the leasing demand for

communications real estate and the wireless industry in general. Actual results may differ materially from those indicated in our

forward-looking statements as a result of various important factors, including: (1) decrease in demand for our communications

sites would materially and adversely affect our operating results, and we cannot control that demand; (2) if our tenants share site

infrastructure to a significant degree or consolidate or merge, our growth, revenue and ability to generate positive cash flows

could be materially and adversely affected; (3) our business is subject to government regulations and changes in current or future

laws or regulations could restrict our ability to operate our business as we currently do; (4) our leverage and debt service

obligations may materially and adversely affect us; (5) if we fail to pay scheduled dividends on our preferred stock, in cash or

common stock, we will be prohibited from paying dividends on our common stock, which may jeopardize our status as a REIT;

(6) increasing competition in the tower industry may materially and adversely affect us; (7) our expansion initiatives involve a

number of risks and uncertainties that could adversely affect our operating results, disrupt our operations or expose us to

additional risk if we are not able to successfully integrate operations, assets and personnel; (8) our foreign operations are subject

to economic, political and other risks that could materially and adversely affect our revenues or financial position, including risks

associated with fluctuations in foreign currency exchange rates; (9) a substantial portion of our revenue is derived from a small

number of tenants, and we are sensitive to changes in the creditworthiness and financial strength of our tenants; (10) we may fail

to realize the growth prospects and cost savings anticipated as a result of our acquisition of MIP Tower Holdings LLC, the parent

company of Global Tower Partners (GTP); (11) new technologies or changes in a tenant’s business model could make our tower

leasing business less desirable and result in decreasing revenues; (12) if we fail to remain qualified as a REIT, we will be subject

to tax at corporate income tax rates, which may substantially reduce funds otherwise available; (13) we may be limited in our

ability to fund required distributions using cash generated through our TRSs; (14) complying with REIT requirements may limit

our flexibility or cause us to forego otherwise attractive opportunities;

Risk Factors

(continued)

(15) certain of our business activities may be subject to corporate level income tax and foreign taxes, which reduce our cash

flows and may create deferred and contingent tax liabilities; (16) we may need additional financing to fund capital expenditures,

future growth and expansion initiatives and to satisfy our REIT distribution requirements; (17) if we are unable to protect our

rights to the land under our towers, it could adversely affect our business and operating results; (18) if we are unable or choose

not to exercise our rights to purchase towers that are subject to lease and sublease agreements at the end of the applicable

period, our cash flows derived from such towers will be eliminated; (19) restrictive covenants in the agreements related to our

securitization transactions, our credit facilities and our debt securities could materially and adversely affect our business by

limiting flexibility; (20) we may incur goodwill and other intangible asset impairment charges, which could result in a significant

reduction to our earnings; (21) our costs could increase and our revenues could decrease due to perceived health risks from

radio emissions, especially if these perceived risks are substantiated; (22) we could have liability under environmental and

occupational safety and health laws; and (23) our towers or data centers may be affected by natural disasters and other

unforeseen events for which our insurance may not provide adequate coverage. For additional information regarding factors that

may cause actual results to differ materially from those indicated in our forward-looking statements, we refer you to the

information contained in Item 1A of our Form 10-Q for the quarter ended June 30, 2014. We undertake no obligation to update

the information contained in this presentation to reflect subsequently occurring events or circumstances.
