Anadarko Petroleum Corporation era una compagnia petrolifera e del gas naturale statunitense, acquisita da Occidental Petroleum nel 2019.

Il mercato obbligazionario presenta un'emissione significativa da parte di Anadarko Petroleum, un'importante società statunitense che ha storicamente operato nel settore dell'esplorazione e produzione di petrolio e gas naturale, rappresentando un attore chiave nell'industria energetica globale con la sua specializzazione nella scoperta e nello sviluppo di risorse in diverse aree geografiche, prima della sua acquisizione da parte di Occidental Petroleum. L'obbligazione in questione, identificata dal codice ISIN US032510AC36 e dal codice CUSIP 032510AC3, è stata emessa negli Stati Uniti e offre un tasso d'interesse fisso del 6,2%, con pagamenti cedolari semestrali che garantiscono un flusso di cassa regolare agli investitori, fino alla sua scadenza fissata al 14 marzo 2040, configurandosi come un titolo a lungo termine. L'ammontare totale dell'emissione è pari a 12.504.000 Dollari statunitensi (USD), la medesima valuta in cui sono denominati i pagamenti, e il lotto minimo di acquisto è stabilito a 2.000 USD. Attualmente, l'obbligazione è scambiata sul mercato al 100% del suo valore nominale, ovvero alla pari, indicando che il suo prezzo di mercato coincide con il valore facciale. Per quanto riguarda la sua qualità creditizia, l'obbligazione è stata valutata BB+ dall'agenzia Standard & Poor's (S&P) e Ba2 dall'agenzia Moody's, posizionandola nella categoria di rating speculativo (o "junk bond"), il che implica un rischio più elevato rispetto ai titoli investment grade.

ANADARKO PETROLEUM CORPORATION

General

Anadarko Petroleum Corporation is among the largest independent oil and gas exploration and
production companies in the world, with 2.3 billion BOE of proved reserves as of December 31,
2009. Our primary business segments are managed separately due to the nature of the products
and services, as well as to the unique technology, distribution and marketing requirements. Our
three operating segments are:

Oil and gas exploration and production--This segment explores for and produces natural gas,
crude oil, condensate and NGLs. Our operations are located onshore United States and in the
deepwater Gulf of Mexico, as well as in Algeria, Brazil, China, Côte d'Ivoire, Ghana,
Indonesia, Mozambique, Sierra Leone and other countries.

Midstream--This segment provides gathering, processing, treating and transportation services
to Anadarko and third-party oil and gas producers. We own and operate natural-gas gathering,
processing, treating and transportation systems in the United States.

Marketing--This segment sells most of our production, as well as hydrocarbons purchased
from third parties. We actively market natural gas, oil and NGLs in the United States, and
actively market oil from Algeria and China.

We own interests in several coal, trona (natural soda ash) and industrial mineral properties
through non-operated joint ventures and royalty arrangements within and adjacent to our land
grant acreage position (Land Grant). The Land Grant consists of land granted by the federal
government in the mid-1800s, which passes through Colorado and Wyoming and into Utah.
Within the Land Grant, we have fee ownership of the mineral rights under approximately
8 million acres.

For a further description of our business, properties and operations, you should read our Annual
Report on Form 10-K for the year ended December 31, 2009 which is incorporated by reference
into this prospectus supplement.

Our principal executive offices are located at 1201 Lake Robbins Dr., The Woodlands, Texas
77380, and our telephone number is (832) 636-1000.

Concurrent tender offers

On March 9, 2010, we announced that we had commenced cash tender offers, which we refer to
as the tender offers, to purchase up to $1 billion in aggregate principal amount of our
http://www.sec.gov/Archives/edgar/data/773910/000095012310023206/h70066b5e424b5.... 9/22/2010

outstanding notes. The tender offers consist of two separate offers: an Any and All Offer and a
Maximum Tender Offer, both made pursuant to an Offer to Purchase distributed to the holders
of the affected notes on March 9, 2010.

In the Any and All Offer, we are offering to purchase any and all of the $950 million aggregate
principal amount currently outstanding of our 6.750% Senior Notes due 2011, which we refer to
as our 6.750% notes. In the Maximum Tender Offer, we are offering to purchase, under certain
conditions, our 6.875% Notes due 2011, which we refer to as our 6.875% notes, of which
$675,000,000 aggregate principal amount is currently outstanding, our 6.125% Notes due 2012,
which we refer to as our 6.125% notes, of which $169,748,000 aggregate principal amount is
currently outstanding, and our 5.000% Notes due 2012, which we refer to as our 5.000% notes,
of which $82,049,000 aggregate principal amount is currently outstanding.

The principal amount of notes to be purchased in the Maximum Tender Offer will be equal to
the difference between $1 billion and the principal amount of notes purchased through the Any
and All Offer. The amounts of each series of notes that are purchased in the Maximum Tender
Offer are prioritized in the following order: our 6.875% notes, our 6.125% notes and our
5.000% notes. The Any and All Offer is scheduled to expire at 5:00 p.m. New York City time,
on March 15, 2010, unless extended. Holders of notes subject to the Any and All Offer must
tender and not withdraw their notes before its expiration date to receive the total consideration,
which is calculated in the manner described below. The Maximum Tender Offer is scheduled to
expire at 5:00 p.m. New York City Time, on April 6, 2010, unless extended. Holders of notes
subject to the Maximum Tender Offer must tender and not withdraw their notes before the early
tender date, which is 5:00 p.m. New York City Time, on March 22, 2010, unless extended, to
receive the total consideration. Holders of notes subject to the Maximum Tender Offer who
tender their notes after the early tender date will receive the tender offer consideration, which is
the total consideration minus $30 per $1,000 principal amount of notes tendered by such holder
that are accepted for purchase. Holders of notes subject to the Maximum Tender Offer who
tender their notes before the early tender date may not withdraw their notes after the early tender
date except in limited circumstances. Holder of notes subject to the Maximum Tender Offer
who tender their notes after the early tender date may not withdraw their notes.

The total consideration for each $1,000 principal amount of notes tendered and accepted for
payment pursuant to the tender offers will be determined by reference to a fixed spread
specified for each series of notes over the yield based on the bid side price of the applicable
reference U.S. Treasury Security, as calculated by the dealer managers at 2:00 p.m. New York
City time, on the expiration date for the Any and All Offer, in the case of the Any and All Offer,
or the early tender date, in the case of the Maximum Tender Offer. In addition to the total
consideration or the tender offer consideration, as applicable, accrued and unpaid interest up to,
but not including, the applicable settlement date will be paid in cash on all validly tendered
notes accepted in the tender offers.

The completion of each tender offer is subject to the satisfaction of certain conditions, including
the completion of this offering, on terms satisfactory to us. Completion of this offering is not
conditioned upon any minimum level of acceptance in the tender offers.

We expect to fund the tender offers with the net proceeds from this offering together with cash
on hand. If any condition of the tender offers is not satisfied, we are not obligated to accept for
purchase, or to pay for, any of the notes tendered and may delay the acceptance for payment of
any tendered notes, in each event subject to applicable laws. We also may terminate, extend or
amend the tender offers and may postpone the acceptance for purchase of, and payment for, the
notes tendered.
This prospectus supplement and the accompanying prospectus are not an offer to purchase the
6.750% notes, the 6.875% notes, the 6.125% notes or the 5.000% notes. The tender offers are
made only by and pursuant to the terms of the Offer to Purchase and the related Letter of
Transmittal, each dated March 9, 2010, as the same may be amended or supplemented.
