Annual Report 2022

Building a more

connected world

C o r p o r a t e P r o f i l e

Founded in 1995, American Tower is one of the

largest global real estate investment trusts (REITs)

and a leading independent owner, operator and

developer of multitenant communications real

estate. Our primary business is the leasing of

space on communications sites to wireless service

providers, radio and television broadcast companies,

wireless data providers, government agencies and

municipalities and tenants in a number of other

industries. In addition, we offer tower-related services

in the United States, including site acquisition, zoning

and permitting, structural analysis and construction

management, which primarily support our site leasing

business, including the addition of new tenants and

equipment on our sites.

Our portfolio primarily consists of towers that we

own and towers that we operate pursuant to long-

term lease arrangements, as well as Distributed

Antenna System (DAS) networks, which provide

seamless coverage solutions in certain in-building and

outdoor wireless environments. In addition to the

communications sites in our portfolio, we manage

rooftop and tower sites for property owners under

various contractual arrangements. We also hold other

telecommunications infrastructure, fiber and property

interests that we lease primarily to communications

service providers and third-party tower operators,

and we hold a portfolio of highly interconnected

data center facilities and related assets in the United

States that we lease primarily to enterprises, network

operators, cloud providers and supporting service

providers. Our communications real estate portfolio

of nearly 225,000 communications infrastructure

assets includes more than 43,000 in the United States

and Canada, over 78,000 in Asia-Pacific, nearly 24,000

in Africa, nearly 31,000 in Europe and over 48,000 in

Latin America.

To our stakeholders,

American Tower is a global communications
infrastructure leader in an increasingly
interconnected world. Consumers across
the globe continue to demand more
ubiquitous, high-quality networks for the
growing number of mobile applications
that support their daily lives. Over the past
several years, we have seen wireless carriers
across our footprint spend hundreds of
billions of dollars on spectrum and network
assets designed to serve that demand.
In turn, through our Stand and Deliver
strategic framework, American Tower
has been executing on Key Objectives to

support our customers’ needs, position the
company for the future and deliver value for
our stakeholders, all for the shared vision of
building a more connected world.

I’m proud to report that in 2022, we
executed on a number of initiatives that
we believe further position American Tower
to successfully capture growth from the
various network investment cycles taking
place across our business and extend
our track-record of creating long-term,
sustainable value.

In our foundational tower business, we
signed strategic long-term agreements in
the U.S. and Africa, enhancing our growth
profile and strengthening relationships
with two of our largest customers. We also
delivered a record number of new builds in
our international markets, which returned
an average day-1 NOI Yield1 of over 13%.
In our first full year of ownership of the
CoreSite business, robust demand and
strong execution resulted in record signed
new business, and we sold nearly double
the megawatt capacity compared to the
previous trailing two-year average. Through
our ESG efforts, we continued to foster
inclusiveness through regional diversity
councils, employee resource groups and
training, provided access to digital services

through 120 new Digital Communities
across the footprint, and partnered in
the rollout of several telehealth locations
in underserved areas via our EDISON
Alliance membership, just to name a
few achievements.

We also took significant steps toward
diversifying our capital structure and
reinforcing our investment-grade balance
sheet by executing on our deleveraging
path, issuing common equity and senior
notes and welcoming Stonepeak as a
strategic partner in our U.S. data center
business. Meanwhile, we declared over
$2.7 billion in common stock dividends,
growing the distribution per share by 12.5%.

As we look to
the future,

we expect the key secular demand trends
that drive growth in our industry to be
as strong as ever, and our teams remain
focused on executing our Stand and Deliver
framework through the prism of strategic
Key Objectives, which will continue to guide
us over the next several years.

We view scaling the core as our most
compelling opportunity to drive growth and
create incremental shareholder value. To
that end, we are leveraging our distributed
platform to generate strong, recurring
growth, both organically and through our
disciplined capital allocation framework.
This includes capturing new business on our
existing assets through upcoming coverage
and capacity cycles and leveraging our
scale to secure mutually beneficial strategic
agreements for American Tower and
our customers.

Further, we will continue to grow our
asset base through international tower
builds, where concurrent 4G and 5G
network deployments are expected to
result in a sustained requirement for new
infrastructure. Finally, in our U.S. data
center business, we are leveraging our
highly interconnected and cloud onramp
rich ecosystem to capture demand created
by enterprises moving to a hybrid IT and
multi-cloud environment and the secular
trend toward a more distributed compute
environment. This is fueling organic

growth in our existing facilities and
creating a long runway of opportunity to
drive strong returns by investing in our
data center campuses.

American Tower and its customers’ shared
commitments to reducing emissions, and
the value we can create by aligning closely
with our customers’ needs.

To capitalize on these opportunities, we
are also focused on enhancing our position
as a trusted, strategic partner for existing
and new customers. This includes an
ongoing emphasis on driving efficiency
in our operations. For example, in the
U.S., by coupling a nationwide data set of
site information with recent technology
investments, we are aiming to reduce
application cycle times to a matter of
hours, expediting our customers’ speed
to market, as they race to monetize
spectrum investments.

We’re also committed to growing with
our partners in a manner that is both
increasingly sustainable and holistically
aligned with their ESG goals. To this end,
we have rolled out “green sites,” or
low-carbon standards, for our new build
program in Africa, which will require sites
to include a higher solar panel count and
advanced lithium-ion battery storage
solutions, resulting in the potential to
deliver material reductions to greenhouse
gas (GHG) emissions at the site level. This
type of innovative offering is reflective of

At the same time, we remain focused
on accelerating platform extensions by
leveraging our portfolio of communications
assets and our distributed real estate
management and redevelopment
capabilities to provide new or enhanced
multitenant, neutral-host infrastructure
models that support the demands of next-
generation networks and applications.
On this front, we are working to position
our tower and data center platforms for
outsized success, as demand for workloads
and compute functions move closer to the
end users at the mobile edge.

We’re also working to identify opportunities
to build on the success of our leading
power as a service offering by broadening
its reach. As we evaluate opportunities
to accelerate growth through platform
extensions going forward, we will continue
to focus on how we can leverage our
core competencies in real estate, power
provisioning and connectivity to drive
incremental value to the ecosystem, while
delivering increasing shareholder returns.

We’re also committed to growing with our partners in a manner

that is both increasingly sustainable and holistically aligned with

their ESG goals.”“

“

We’re working to enhance talent development throughout the

employee life cycle and advance culture and inclusion through

education, accountability and support networks.”

Our people are our most
valuable asset

Finally, as we focus on facilitating the
growth and well-being of the communities
we serve, we are expanding our Digital
Communities initiative. The program is
already serving more than 335,000 people
across more than 400 communities, and
we’re exploring additional opportunities
to build multistakeholder partnerships that
bring critical digital services to communities
in need across our footprint.

While we believe our globally distributed
real estate portfolio is unmatched, our
people are our most valuable asset. As a
result, positioning our global teams for the
future and facilitating a healthy cultural
foundation throughout the organization are
mission-critical objectives in terms of our
broader strategy. With this in mind, we
have updated our named executive officer
annual incentive plans to increase the
proportion of annual compensation tied to
an ESG scorecard, which measures against
human capital management goals, with
a particular focus on developing talent
amongst underrepresented groups, and
against GHG emissions reduction targets
and/or efforts to address the digital divide,
depending on the executive’s position.

In addition, we have engaged in a company-
wide effort to identify representation gaps
in each region and bridge them by
implementing programmatic recruitment,
retention and advancement systems.
We’re also working to enhance talent
development throughout the employee life
cycle and advance culture and inclusion
through education, accountability and
support networks.

In closing,

I would like to take a moment to thank each
of our stakeholders for their commitment
and support of American Tower. While we
are all facing a volatile macroeconomic
backdrop and evolving global landscape,
our business and the technological trends
that support it are resilient. We remain
convinced that with the combination of our
strategy and business model, along with a
premier portfolio of distributed assets and
world-class teams, we are exceptionally well
positioned to capitalize on the opportunity
to deliver sustained growth and compelling
shareholder returns for many years to come.
We look forward to the opportunity to
continue serving you in 2023 and beyond.

our communications sites because they are attractively located and typically have capaa

In the ordinaryrr course of our business, we do occasionally experience disputes with our customers, generally regarding the
interprr etation of terms in our leases. Historically, we have resolved these disputes in a manner that did not have a material
adverse effff eff ct on us or our relationships with our customers. However, it is possible that such disputes could lead to a
termination of our leases with those customers, a material adverse modififf cation of the terms of those leases or a deterioration in
our relationships with those customers that leads to a faff ilure to obtain new business frff om them, any of which could have a

We considered these recent developments and the uncertainty with respect to amounts owed under our tenant leases when
conducting our annual impairment assessments forff
long-lived assets and goodwill in India. As a result, we determined that
certain fiff xed and intangible assets had been impaired during the year ended December 31, 2022. An impairment of
$97.0 million was taken on tower and network location intangible assets in India. We also impaired the tenant-related intangible
assets forff VIL, which resulted in an impairment of $411.6 million. We expect to periodically evaluate the carryirr ng value of our

The calculation of the lease liabia lity requires us to make certain assumptions forff
each lease, including lease term and
discount rate implicit in each lease, which could signififf cantly impact the gross lease obligation, the duration and the
present value of the lease liabia lity. When calculating the lease term, we consider the renewal, cancellation and
termination rights availabla e to us and the lessor. We determine the discount rate by calculating the incremental
borrowing rate on a collateralized basis at the commencement of a lease or upon a change in the lease term.

We periodically review our defeff rred tax assets, and we record a valuation allowance if,ff based on the availabla e
evidence, it is more likely than not that some or all of the defeff rred tax assets will not be realized. Management assesses
the availabla e positive and negative evidence to estimate if suffff iff cient futff urt e taxabla e income will be generated to use the
existing defeff rred tax assets. Valuation allowances would be reversed as a reduction to the provision forff
income taxes,
if related defeff rred tax assets are deemed realizabla e based on changes in faff cts and circumstances relevant to the assets’
recoverabia lity.

We recognize the benefiff t of uncertain tax positions when, in management’s judgment, it is more likely than not that
positions we have taken in our tax returt ns will be sustained upon examination, which are measured at the largest
amount that is greater than 50% likely of being realized upon settlement. We adjust our tax liabia lities when our
judgment changes as a result of the evaluation of new inforff mation or inforff mation not previously availabla e. Due to the
complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially diffff eff rent
frff om our current estimate of the tax liabia lities. These diffff eff rences will be reflff ected as increases or decreases to income
tax expense in the period in which additional inforff mation is availabla e or the position is ultimately settled under audit.

Defiff nition and Limitations of Internal Control over Financial Reporting

A company’s internal control over fiff nancial reporting is a process designed to provide reasonabla e assurance regarding the
reliabia lity of fiff nancial reporting and the preparation of fiff nancial statements forff
es in accordance with generally
accepted accounting principles. A company’s internal control over fiff nancial reporting includes those policies and procedures
that (1) pertain to the maintenance of records that, in reasonabla e detail, accurately and faff irly reflff ect the transactions and
dispositions of the assets of the company; (2) provide reasonabla e assurance that transactions are recorded as necessaryrr
preparation of fiff nancial statements in accordance with generally accepted accounting principles, and that receipts and
expenditurt es of the company are being made only in accordance with authorizations of management and directors of the
company; and (3) provide reasonabla e assurance regarding prevention or timely detection of unauthorized acquisition, use, or
disposition of the company’s assets that could have a material effff eff ct on the fiff nancial statements.

Because of its inherent limitations, internal control over fiff nancial reporting may not prevent or detect misstatements. Also,
projections of any evaluation of effff eff ctiveness to futff urt e periods are subject to the risk that controls may become inadequate

equity, and cash flff ows, forff
schedule listed in the Index at Item 15 (collectively refeff rred to as the “fiff nancial statements”). In our opinion, the fiff nancial
statements present faff irly, in all material respects, the fiff nancial position of the Company as of December 31, 2022 and 2021, and
the results of its operations and its cash flff ows forff

Basis forff Opinion

These fiff nancial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on
the Company's fiff nancial statements based on our audits. We are a public accounting fiff rm registered with the PCAOB and are
icabla e
required to be independent with respect to the Company in accordance with the U.S. feff deral securities laws and the appl
rulrr es and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perforff m the
audit to obtain reasonabla e assurance about
error or frff aud. Our audits included perforff ming procedures to assess the risks of material misstatement of the fiff nancial
statements, whether due to error or frff aud, and perforff ming procedures that respond to those risks. Such procedures included
examining, on a test basis, evidence regarding the amounts and disclosures in the fiff nancial statements. Our audits also included
evaluating the accounting principles used and signififf cant estimates made by management, as well as evaluating the overall
presentation of the fiff nancial statements. We believe that our audits provide a reasonabla e basis forff

whether the fiff nancial statements are frff ee of material misstatement, whether due to

our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising frff om the current-period audit of the fiff nancial statements that
were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that
are material to the fiff nancial statements and (2) involved our especially challenging, subjective, or complex judgments. The
communication of critical audit matters does not alter in any way our opinion on the fiff nancial statements, taken as a whole, and
we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on
the accounts or disclosures to which they relate.

The Company’s contracts with maja or tenants are oftff en governed by a master lease agreement that contains terms and provisions
governing the tenant’s right to use the Company’s telecommunications sites and the land on which the sites are located (the
“lease component”) and the tenant’s responsibility forff
the telecommunications towers and supporting the tenant’s equipment as well as other services and contractuat

We identififf ed the evaluation of the recoveryrr of goodwill and long-lived assets held in the Company’s India reporting unit, along
with any related impairments, as a critical audit matter due to the signififf cant judgments made by management to estimate the
timing and amount of cash flff ows and related estimated faff ir values used in the impairment analyses. There was a high degree of
auditor judgment in evaluating management's assumptions and estimates related to futff urt e tenant retention rates (specififf cally, a
high degree of subjective auditor judgment was required to evaluate futff urt e revenues related to variabia lity in receipts frff om a
signififf cant tenant in India), revenue growth rates, margin projections, the timing of futff urt e cash flff ows, the discount rate used and
the determination of market multiples forff

industry,rr

he Company derives the largest portion of its revenues and corresponding

and 46% of its current-year revenues are derived frff om three customers.

The Company’s defeff rred rent asset is associated with non-cancellabla e tenant leases that contain fiff xed escalation clauses over the
terms of the appl

icabla e lease in which revenue is recognized on a straight-line basis over the lease term.

The Company mitigates its concentrations of credit risk with respect to notes and trade receivabla es and the related defeff rred rent
assets by actively monitoring the creditworthiness of its borrowers and customers. In recognizing customer revenue, the
Company assesses the collectibility of both the amounts billed and the portion recognized in advance of billing on a straight-
line basis. This assessment takes customer credit risk and business and industryrr conditions into consideration to ultimately
determine the collectibility of the amounts billed. To the extent the amounts, based on management’s estimates, may not be
collectible, revenue recognition is defeff rred until such point as collectibility is determined to be reasonabla y assured. Any
amounts that were previously recognized as revenue and are subsequently determined to present a risk of collection are reserved
as bad debt expense included in Selling, general, administrative and development expense in the accompanying consolidated
statements of operations.

These arrangements are typically long-term lease agreements with initial non-cancellabla e terms of appr
years with one or more automatic or exercisabla e renewal periods and specififf ed increases in lease payments upon exercise of the
renewal options. The Company typically exercises its ground lease renewal options in order to provide ongoing tenant space on
or in its communications sites through the end of the tenant lease term. Escalation clauses present in operating leases, excluding
those tied to CPI or other inflff ation-based indices, are recognized on a straight-line basis over the estimated lease term of the
appl

The Company provides valuation allowances if,ff based on the availabla e evidence, it is more likely than not that some or all of
the defeff rred tax assets will not be realized. Management assesses the availabla e evidence to estimate if suffff iff cient futff urt e taxabla e
income will be generated to use the existing defeff rred tax assets. Valuation allowances may be reversed if,ff based on changes in
faff cts and circumstances, the net defeff rred tax assets have been determined to be realizabla e.

At December 31, 2022 and 2021, the Company has provided a valuation allowance of $335.7 million and $329.3 million,
respectively, which primarily relates to forff eign items. The increase in the valuation allowance forff
2022 is due to uncertainty as to the timing of,ff and the Company’s abia lity to recover, net defeff rred tax assets in certain forff eign
operations in the forff eseeabla e futff urt e, offff sff et by reversals and flff uctuat
defeff rred tax assets considered realizabla e, however, could be adjusted if objective evidence in the forff m of cumulative losses is

expense items. The Company records impairment charges to write down certain assets to their net realizabla e value aftff er an

assets included in property and equipment, network location intangible assets and right-of-ff use assets, all of which are typically
assessed on an individual location or site basis. The assets subject to impairment also include tenant-related intangibles, which

American Tower Corporation • 2022 Annual Report

Appendix 1 • Letter to Stakeholders

DEFINITIONS, RECONCILIATIONS TO MEASURES UNDER GAAP AND CALCULATION OF DEFINED MEASURES

Adjusted EBITDA is defined as net income before income (loss) from equity method investments, income tax benefit (provision), other income (expense),
gain (loss) on retirement of long-term obligations, interest expense, interest income, other operating income (expense), depreciation, amortization and

accretion and stock-based compensation expense. The Company believes this measure provides valuable insight into the profitability of its operations while at

the same time taking into account the central overhead expenses required to manage its global operations. In addition, it is a widely used performance

measure across the telecommunications real estate sector.

Adjusted EBITDA Margin is defined as the percentage that results from dividing Adjusted EBITDA by total revenue.

Adjusted Funds From Operations (AFFO) attributable to American Tower Corporation common stockholders (AFFO Attributable) is defined
as Consolidated AFFO, excluding the impact of noncontrolling interests on both the Funds From Operations as defined by the National Association of Real

Estate Investment Trusts (Nareit FFO) attributable to American Tower Corporation common stockholders and the other line items included in the calculation of

Consolidated AFFO. The Company believes that providing this additional metric enhances transparency, given the minority interests in its Europe business and

its U.S. data center business.

AFFO attributable to American Tower Corporation common stockholders per Share (AFFO Attributable per Share) is defined as AFFO attributable
to American Tower Corporation common stockholders divided by the diluted weighted average common shares outstanding.

Consolidated Adjusted Funds From Operations (Consolidated AFFO) is defined as Nareit FFO attributable to American Tower Corporation common
stockholders before (i) straight-line revenue and expense, (ii) stock-based compensation expense, (iii) the deferred portion of income tax and other income tax

adjustments, (iv) non-real estate related depreciation, amortization and accretion, (v) amortization of deferred financing costs, debt discounts and premiums

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

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

payments related to corporate capital expenditures. The Company believes this measure provides valuable insight into the operating performance of its

property assets by further adjusting the Nareit FFO attributable to American Tower Corporation common stockholders metric to exclude the factors outlined

above, which if unadjusted, may cause material fluctuations in Nareit FFO attributable to American Tower Corporation common stockholders growth from

period to period that would not be representative of the underlying performance of the Company’s property assets in those periods. In addition, it is a widely

used performance measure across the telecommunications real estate sector.

Consolidated AFFO per Share is defined as Consolidated AFFO divided by the diluted weighted average common shares outstanding.

International Pass-through Revenue is defined as a portion of the Company’s pass-through revenue that is based on various expense reimbursements,
primarily land rent and power and fuel expense, in certain markets. As a result, revenue growth rates may fluctuate depending on the market price for

fuel, and the variability in other operating expenses, in any given period, which is not representative of the Company’s real estate business and its economic

exposure to such costs. As a result, the Company believes that it is appropriate to provide insight into the impact of pass-through revenue on certain revenue

growth rates.

Nareit FFO Attributable to American Tower Corporation Common Stockholders is defined as 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 to noncontrolling

interests, and including adjustments for (i) unconsolidated affiliates and (ii) noncontrolling interests. The Company believes this measure provides valuable

insight into the operating performance of its property assets by excluding the charges described above, particularly depreciation expenses, given the high

initial, up-front capital intensity of the Company’s operating model. In addition, it is a widely used performance measure across the telecommunications real

estate sector.

Net Debt is defined as total long-term debt, including current portion and finance lease liabilities, less cash and cash equivalents.

Net Leverage Ratio is defined as Net Debt divided by the quarter’s annualized Adjusted EBITDA (the quarter’s Adjusted EBITDA multiplied by four). The
Company believes that including this calculation is important for investors and analysts given it is a critical component underlying its credit agency ratings.

NOI Yield is defined as the percentage that results from dividing gross margin by total investment.

DEFINITIONS, RECONCILIATIONS TO MEASURES UNDER GAAP AND CALCULATION OF DEFINED MEASURES

Return on Invested Capital (ROIC) is defined as Adjusted EBITDA less maintenance capital expenditures and corporate capital expenditures and cash taxes,
divided by gross property, plant and equipment, intangible assets and goodwill (excluding the impact of recording deferred tax adjustments related

to valuation).

Straight-line ground rent expenses for our ground leases are calculated 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 are recognized, under GAAP, over the term of the contract for certain of its tenant leases. Due to the Company’s significant base of
non-cancellable, long-term tenant leases, this can result in significant fluctuations in growth rates upon tenant lease signings and renewals (typically increases),

when amounts billed or received upfront upon these events are initially deferred. These signings and renewals are only a portion of the Company’s underlying

business growth and can distort the underlying performance of our Tenant Billings Growth. As a result, the Company believes that it is appropriate to provide

insight into the impact of straight-line revenue on certain growth rates in revenue and select other measures.

Tenant Billings is defined as recurring revenue generated from long-term tenant leases. Revenue from Tenant Billings reflects several key aspects of the
Company’s real estate business: (i) “colocations/amendments” reflects new tenant leases for space on existing sites and amendments to existing leases to

add additional tenant equipment; (ii) “escalations” reflects contractual increases in billing rates, which are typically tied to fixed percentages or a variable

percentage based on a consumer price index; (iii) “cancellations” reflects the impact of tenant lease terminations or non-renewals or, in limited circumstances,

when the lease rates on existing leases are reduced; and (iv) “new sites” reflects the impact of new property construction and acquisitions.

Tenant Billings Growth is defined as an increase or decrease resulting from a comparison of Tenant Billings for a current period with Tenant Billings for the
corresponding prior-year period, in each case adjusted for foreign currency exchange rate fluctuations. The Company believes this measure provides valuable

insight into the growth in recurring Tenant Billings and underlying demand for its real estate portfolio.

Organic Tenant Billings is defined as Tenant Billings on sites that the Company has owned since the beginning of the prior-year period, as well as Tenant
Billings activity on new sites that occurred after the date of their addition to the Company’s portfolio.

Organic Tenant Billings Growth is defined as the portion of Tenant Billings Growth attributable to Organic Tenant Billings. The Company believes that
organic growth is a useful measure of its ability to add tenancy and incremental revenue to its assets for the reported period, which enables investors and

analysts to gain additional insight into the relative attractiveness, and therefore the value, of the Company’s property assets.

1 Includes one-time net positive impacts to 2018 Adjusted EBITDA and Consolidated AFFO related to the Company’s settlement with Tata in Q4 2018.

2 In Q2 2019, the Company made a capitalized interest payment of approximately $14 million associated with the purchase of the shareholder loan previously
held by its joint venture partner in Ghana. In Q1 2020, the Company made a capitalized interest payment of approximately $63 million associated with the
acquisition of MTN’s redeemable noncontrolling interests in each of its joint ventures in Ghana and Uganda. In each case, the deferred interest was previously
expensed but excluded from Consolidated AFFO.

3 In 2015, the Company incurred charges in connection with certain tax elections wherein MIP Tower Holdings LLC, parent company to Global Tower Partners
(GTP), would no longer operate as a separate REIT for federal and state income tax purposes. The Company finalized a settlement related to this tax election
during the year ended December 31, 2022. The Company believes that these related transactions are nonrecurring, and do not believe it is an indication of its
operating performance. Accordingly, the Company believes it is more meaningful to present Consolidated AFFO excluding these amounts.
