NOTICE TO INVESTORS

This earnings report supplement contains certain "forward-looking statements" within the meaning of Section 27A of the Securities

Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended and, whenever possible, are identified

by use of the words such as “anticipates,” “intends,” “plans,” “seeks,” “believes,” “estimates,” “expects” and similar references to

future periods. Any matters that are not historical facts are forward-looking and, accordingly, involve estimates, assumptions, risks

and uncertainties, including, without limitation, our assumptions about the market prices of oil, natural gas, NGLs and other products

or services, our commodity hedging arrangements, the supply and demand for oil, natural gas, NGLs and other products or services,

production and reserve levels, drilling risks, economic and competitive conditions, the availability of capital resources, capital

expenditure and other contractual obligations, and other factors discussed in our most recently filed Annual Report on Form 10-K,

recent Quarterly Reports on Form 10-Q and recent Current Reports on Form 8-K, and amendments thereto, available on our Web site

and in our other public filings and press releases. There is no assurance that Apache's expectations will be realized, and actual results

may differ materially from those expressed in the forward-looking statements. Unless otherwise required by law, we assume no duty

to update these statements as of any future date.

Cautionary Note to Investors: The United States Securities and Exchange Commission ("SEC") permits oil and gas companies, in their

filings with the SEC, to disclose only proved, probable, and possible reserves that meet the SEC's definitions for such terms. Apache

may use certain terms in this release, such as resources, potential resources, reserves potential and other similar terms that the SEC

guidelines strictly prohibit Apache from including in filings with the SEC. Such terms do not take into account the certainty of

resource recovery, which is contingent on exploration success, technical improvements in drilling access, commerciality and other

factors, and are therefore not indicative of expected future resource recovery and should not be relied upon. Investors are urged to

consider carefully the disclosure in Apache’s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, available

from Apache at www.apachecorp.com or by writing Apache at: 2000 Post Oak Blvd., Suite 100, Houston, Texas 77056 (Attn:

Corporate Secretary). You can also obtain this report from the SEC by calling 1-800-SEC-0330 or from the SEC's website at

www.sec.gov.

Certain information provided in this supplement includes financial measurements that are not required by, or presented in accordance

with, generally accepted accounting principles (GAAP), including these measures: adjusted earnings, pre-tax margin, and cash from

operations. These non-GAAP measures should not be considered as alternatives to GAAP measures, such as net income or cash from

operating activities, and may be calculated differently from, and therefore may not be comparable to, similarly titled measures used at

other companies. Reconciliation to the most directly comparable GAAP financial measure has been provided.

None of the information contained in this document has been audited by any independent auditor. This supplemental document is

prepared as a convenience for securities analysts and investors and may be useful as a reference tool. Apache intends to continue to

publish this supplement in conjunction with our quarterly earnings release, but may elect to modify the format or discontinue

publication at any time, without notice to securities analysts or investors.

APACHE CORPORATION ADJUSTED EARNINGS

(in millions, except per share data)

14

Reconciliation of income attributable to common stock to adjusted earnings:

Our press release discusses Apache’s adjusted earnings. Adjusted earnings exclude certain items that management believes affect the

comparability of operating results and are meaningful for the following reasons:

Management uses adjusted earnings to evaluate the company’s operational trends and performance relative to other oil and gas

producing companies.

Management believes this presentation may be useful to investors who follow the practice of some industry analysts who adjust

reported company earnings for items that may obscure underlying fundamentals and trends.

The reconciling items above are the types of items management believes are frequently excluded by analysts when evaluating the

operating trends and comparability of the company’s results.

APACHE CORPORATION CASH FROM OPERATIONS (in millions, except per share data)

15

Reconciliation of net cash provided by operating activities to cash from operations before changes in operating assets and liabilities:

Our press release discusses Apache’s cash from operations before changes in operating assets and liabilities. It is presented because

management believes the information is useful for investors because it is used internally and widely accepted by those following the

oil and gas industry as a financial indicator of a company’s ability to generate cash to internally fund exploration and development

activities, fund dividend programs, and service debt. It is also used by research analysts to value and compare oil and gas exploration

and production companies, and is frequently included in published research when providing investment recommendations. Cash from

operations before changes in operating assets and liabilities, therefore, is an additional measure of liquidity, but is not a measure of

financial performance under GAAP and should not be considered as an alternative to cash flows from operating, investing, or

financing activities.

The following table reconciles net cash provided by operating activities to cash from operations before changes in operating assets and

liabilities.

APACHE CORPORATION PRE-TAX AND CASH MARGINS


16

Reconciliation of Non-GAAP Margin Disclosure:

Apache calculates both pre-tax and cash margins. Management believes that a cash margin is more representative of the Company’s performance, as

non-cash items (DD&A and Asset Retirement Obligation Accretion) distort the actual funds generated during the period.
