**Remboursement de l'Obligation American Tower Corp (US03027XAB64) : Bilan d'une Émission Arrivée à Maturité** Le marché obligataire a récemment vu l'achèvement d'une émission notable, l'obligation d'American Tower Corporation (ISIN : US03027XAB64), qui est arrivée à pleine maturité et a été intégralement remboursée à sa valeur nominale. Cette opération met en lumière les caractéristiques et la performance de ce titre de dette émis par un acteur majeur des infrastructures de télécommunications. L'émetteur, **American Tower Corporation**, est une société américaine de premier plan, cotée en bourse et reconnue comme un fonds de placement immobilier (REIT) spécialisé dans les infrastructures de télécommunications. Son activité principale consiste à posséder, exploiter et louer des tours de communication multi-locataires et des actifs immobiliers connexes pour le secteur sans fil et de la diffusion. Avec une présence mondiale significative et une base d'actifs étendue, American Tower est un acteur clé dans la fourniture d'infrastructures essentielles à la connectivité numérique, générant des revenus stables grâce à des contrats de location à long terme avec les opérateurs mobiles. La société opère principalement aux États-Unis mais a également une empreinte internationale importante. L'obligation en question, identifiée par le code ISIN US03027XAB64 et le code CUSIP 03027XAB6, était une émission de dette libellée en dollars américains (USD). Son taux d'intérêt nominal était fixé à 3,5% par an, avec des paiements de coupons effectués à une fréquence semestrielle (deux fois par an). Le montant total de l'émission s'élevait à 1 milliard de dollars américains (1 000 000 000 USD), offrant une liquidité substantielle sur le marché secondaire. L'investissement minimal pour les acquéreurs était fixé à 2 000 USD. La date de maturité de cette obligation était le 29 janvier 2023. Conformément à cette échéance, le titre a été remboursé à 100% de sa valeur nominale, confirmant le respect des engagements contractuels par l'émetteur et offrant aux détenteurs un retour sur capital intégral. La qualité de crédit de l'émetteur et de cette émission obligataire était attestée par des notations attribuées par des agences de notation de premier plan. Standard & Poor's (S&P) avait attribué une notation de BBB-, tandis que Moody's avait noté l'obligation Baa3. Ces deux notations se situent dans la catégorie "investissement" (Investment Grade), indiquant un risque de crédit modéré et une capacité jugée adéquate de l'émetteur à honorer ses obligations financières. Le remboursement réussi de cette obligation d'American Tower Corp illustre la fiabilité des titres de dette émis par des entreprises solides et bien notées, offrant aux investisseurs un retour sur investissement prévisible jusqu'à l'échéance.

We are responsible for the information contained and incorporated by reference in this prospectus supplement and
accompanying prospectus. We have not, and the underwriters have not, authorized anyone to give you any other information,
and we take no responsibility for any other information that others may give you. We are not making an offer to sell these
securities in any jurisdiction where the offer or sale is not permitted. You should not assume that the information contained or
incorporated by reference in this prospectus supplement or accompanying prospectus is accurate as of any date other than the
date of the document containing the information.

ABOUT THIS PROSPECTUS SUPPLEMENT

This document consists of two parts. The first part is this prospectus supplement, which describes the specific terms of this
offering. The second part is the accompanying prospectus, which describes more general information, some of which may not apply to
this offering. You should read both this prospectus supplement and the accompanying prospectus, together with the documents
incorporated by reference and the additional information described below under the heading "Where You Can Find More
Information."

If the description of the offering varies between this prospectus supplement and the accompanying prospectus, you should rely
on the information in this prospectus supplement.

Any statement made in this prospectus supplement or in a document incorporated or deemed to be incorporated by reference in
this prospectus supplement will be deemed to be modified or superseded for purposes of this prospectus supplement to the extent that
a statement contained in this prospectus supplement or in any other subsequently filed document that is also incorporated or deemed to
be incorporated by reference in this prospectus supplement modifies or supersedes that statement. Any statement so modified or
superseded will not be deemed, except as so modified or superseded, to constitute a part of this prospectus supplement.

NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus supplement and accompanying prospectus contain or incorporate by reference statements about future events
and expectations, or forward-looking statements, all of which are inherently uncertain. We have based those forward-looking
statements on our current expectations and projections about future results. When we use words such as "anticipates," "intends,"
"plans," "believes," "estimates," "expects," or similar expressions, we do so to identify forward-looking statements. Examples of
forward-looking statements include statements we make regarding our ability to qualify or to remain qualified as a real estate
investment trust ("REIT"); the amount and timing of any future distributions including those we are required to make as a REIT; our
substantial leverage and debt service obligations; future prospects of growth in the communications site leasing industry; the level of
future expenditures by companies in this industry and other trends in this industry; the effects of consolidation among companies in our
industry and among our customers and other competitive pressures; economic, political and other events, particularly those relating to
our international operations; our ability to maintain or increase our market share; changes in environmental, tax and other laws; our
ability to protect our rights to the land under our towers; natural disasters and similar events; the possibility of health risks relating to
radio emissions; our future operating results; our future purchases under our stock repurchase program; our future capital expenditure
levels; our future financing transactions; and our plans to fund our future liquidity needs. These statements are based on our
management's beliefs and assumptions, which in turn are based on currently available information. These assumptions could prove
inaccurate. See "Risk Factors." These forward-looking statements may be found in this prospectus supplement and the accompanying
prospectus generally as well as the documents incorporated by reference.

You should keep in mind that any forward-looking statement we make in this prospectus supplement, the accompanying
prospectus, the documents incorporated by reference or elsewhere speaks only as of the date on which we make it. New risks and
uncertainties arise from time to time, and it is impossible for us to predict these

events or how they may affect us. In any event, these and other important factors, including those set forth under the caption "Risk
Factors" in this prospectus supplement, in the accompanying prospectus and the documents incorporated by reference, may cause
actual results to differ materially from those indicated by our forward-looking statements. We do not intend to update or revise the
forward-looking statements we make in this prospectus supplement, the accompanying prospectus, the documents incorporated by
reference or elsewhere, except as may be required by law. In light of these risks and uncertainties, you should keep in mind that the
future events or circumstances described in any forward-looking statement we make in this prospectus supplement, the accompanying
prospectus, the documents incorporated by reference or elsewhere might not occur.

MARKET AND INDUSTRY DATA

This prospectus supplement and accompanying prospectus contain or incorporate by reference estimates regarding market data,
which are based on our internal estimates, independent industry publications, reports by market research firms and/or other published
independent sources. In each case, we believe these estimates are reasonable. However, market data is subject to change and cannot
always be verified with complete certainty due to limits on the availability and reliability of raw data, the voluntary nature of the data
gathering process and other limitations and uncertainties inherent in any statistical survey of market data. As a result, you should be
aware that market data set forth in this prospectus supplement, accompanying prospectus or incorporated by reference, and estimates
and beliefs based on such data, may not be reliable.

PROSPECTUS SUPPLEMENT SUMMARY

This summary may not contain all the information that may be important to you. You should read this entire prospectus
supplement, the accompanying prospectus and those documents incorporated by reference into the prospectus supplement and the
accompanying prospectus, including the risk factors and the financial statements and related notes, before making an investment
decision. Unless otherwise indicated or the context otherwise requires, references to "we," "us," "our" and "American Tower"
are references to American Tower Corporation and its predecessor, as applicable, and its consolidated subsidiaries as the context

as applicable.

American Tower Corporation

American Tower Corporation was created as a subsidiary of American Radio Systems Corporation in 1995 to own, manage,
develop and lease communications and broadcast tower sites, and was spun off into a free-standing public company in 1998. Since
inception, we have grown our communications site portfolio through acquisitions, long-term lease arrangements, development and
construction, and through mergers with, and acquisitions of, other tower operators, increasing the size of our portfolio to over 53,000
communications sites.

To effect its conversion to a REIT for federal income tax purposes, effective December 31, 2011, American Tower Corporation
merged with and into its wholly owned subsidiary, American Tower REIT, Inc. American Tower REIT, Inc., the surviving
corporation, was renamed American Tower Corporation and began operating as a REIT for federal income tax purposes effective
January 1, 2012.

American Tower Corporation is a holding company, and we conduct our operations through our directly and indirectly owned
subsidiaries. Our principal United States operating subsidiaries are American Towers LLC and SpectraSite Communications, LLC.
We conduct our international operations through our subsidiary, American Tower International, Inc., which in turn conducts operations
through its various international operating subsidiaries and joint ventures. Our international operations consist primarily of our
operations in Brazil, Chile, Colombia, Germany, Ghana, India, Mexico, Peru, South Africa and Uganda.


Our principal executive office is located at 116 Huntington Avenue, Boston, Massachusetts 02116. Our main telephone number
at that address is (617) 375-7500.

RECENT DEVELOPMENTS

Credit Facilities

Credit Facility") and an aggregate of $992.0 million under our $1.0 billion unsecured revolving credit facility entered into in January
2012 (the "2012 Credit Facility"), which amounts were primarily used to fund certain acquisitions completed during the fourth

On November 30, 2012, we repaid all amounts outstanding under the Colombian short-term credit facility our Colombian
subsidiary entered into in July 2011 (the "Colombian Short-Term Credit Facility") with 135.0 billion Colombian Pesos ("COP")
drawn under our new COP denominated secured long-term credit facility, which our Colombian subsidiary entered into in October
2012 (the "Colombian Long-Term Credit Facility"). The November 2012 borrowing under the Colombian Long-Term Credit Facility
approximated $74.3 million at the time of transaction and $75.0 million as of September 30, 2012.

other capital projects.

THE OFFERING

Issuer
American Tower Corporation, a Delaware corporation.

Securities Offered
$1 billion aggregate principal amount of 3.50% senior notes due 2023.

Maturity Date
January 31, 2023.

Interest Payments
January 31 and July 31 of each year, beginning on July 31, 2013. Interest will
accrue from January 8, 2013.

Ranking
The notes will be general, unsecured obligations and will rank equally in right of
payment with all of our other senior unsecured debt obligations. As of September
30, 2012, after giving effect to the transactions described under "Capitalization,"
we would have had approximately $6,316.1 million of senior unsecured
indebtedness outstanding. In addition, we would have had approximately
$1,717.0 million in aggregate undrawn loan commitments under our 2011 Credit
Facility and our 2012 Credit Facility, net of approximately $9.4 million of
outstanding undrawn letters of credit.


The notes will be structurally subordinated to all existing and future indebtedness
and other obligations of our subsidiaries. Our subsidiaries are not guarantors of
the notes. As of September 30, 2012, after giving effect to the transactions
described under "Capitalization," our subsidiaries would have had approximately
$2,454.3 million of total debt obligations (excluding intercompany obligations),
including:

· $1,750.0 million in commercial mortgage pass-through certificates backed by
the debt of two special purpose subsidiaries, which is secured primarily by

mortgages on those subsidiaries' interests in 5,280 broadcast and wireless
communications towers and the related tower sites;

· $100.3 million of subsidiary South African Rand denominated secured debt

(834.3 million South African Rand);

· $52.2 million of subsidiary COP denominated debt (94.0 billion COP);

Colombian Long-Term Credit Facility;

consolidation of the portion of the debt loaned by our wholly owned
subsidiaries);

Table of Contents
· $207.6 million in secured cellular site revenue notes ($196.0 million principal
amount due at maturity plus $11.6 million of unamortized premium) secured by,

among other things, liens on approximately 1,470 real property interests and
assumed by us in connection with the acquisition of certain legal entities from
Unison Holdings, LLC and Unison Site Management II, L.L.C.; and

· approximately $53.6 million of other debt, which consists primarily of capital

leases attributable to wholly owned subsidiaries.

Optional Redemption
We may redeem the notes at any time, in whole or in part, in cash, at a redemption
price equal to 100% of the principal amount of the notes plus a make-whole
premium, together with accrued interest to the redemption date.

Change of Control Offer
Following a Change of Control and Ratings Decline (each as defined herein), we
will be required to offer to purchase all of the notes at a purchase price equal to
101% of the aggregate principal amount of the notes repurchased, plus accrued and
unpaid interest, if any, up to but not including the date of repurchase. See
"Description of Notes--Repurchase of Notes Upon a Change of Control
Triggering Event." The 2011 Credit Facility and the 2012 Credit Facility might
restrict our ability to make such a payment.

Certain Covenants
The provisions of the indenture governing the notes will, among other things, limit
our ability to:

· create liens; and

· merge, consolidate or sell assets.


These covenants are subject to a number of important exceptions.

Use of Proceeds
We expect that the net proceeds of this offering will be approximately $983.4
million, after deducting discounts and commissions payable to the underwriters
and estimated expenses of this offering payable by us. We intend to use the net
proceeds to refinance some or all of the existing indebtedness incurred under the
2011 Credit Facility and/or the 2012 Credit Facility, which was primarily used to
fund recent acquisitions. Subject to the terms of our credit facilities, amounts
outstanding thereunder that are repaid may be re-borrowed at a later date. See
"Use of Proceeds" and "Capitalization."

Conflicts of Interest
As described in "Use of Proceeds," the net proceeds of this offering will be used
to pay down borrowings under the 2011 Credit Facility and/or the 2012 Credit
Facility. Because more than 5% of the proceeds of this offering, not including
underwriting compensation, may be received by affiliates of certain underwriters
in this offering, this offering is being conducted in compliance with Financial
Industry Regulatory Authority ("FINRA") Rule 5121. Pursuant to that rule, the
appointment of a "qualified independent underwriter" is not necessary in
connection with this offering.
