Year End 2012 Financial Results

Production for 2012 totaled 29.8 MMBoe (18.0 million barrels of oil (“MMBbls”) and 70.6 billion cubic feet of natural gas (“Bcf”)), an increase of 26% as compared to 23.6 MMBoe (14.7 MMBbls and 53.7 Bcf) produced in 2011.

Tim Leach, Concho's Chairman, CEO and President, commented, “In 2012, Concho was able to execute our $1.5 billion capital program and grow production in excess of 20% organically. In addition, we positioned the Company for future growth in emerging areas such as the Delaware Basin through the acquisition of Three Rivers and internally identified drilling locations. Today, our opportunity set is deeper than at any time in the Company’s history and we look forward to executing on our inventory of high rate of return projects.”

For 2012, the Company reported net income of $431.7 million, or $4.15 per diluted share, as compared to net income of $548.1 million, or $5.28 per diluted share, for 2011. The Company’s 2012 results were impacted by several non-cash items including: (1) a $103.9 million unrealized mark-to-market gain on commodity derivatives, (2) $12.4 million of leasehold abandonments, (3) $3.2 million of other settlements and (4) an $18.7 million loss related to the sale of non-core assets included in discontinued operations. Excluding these items and their tax effects, the 2012 adjusted net income (non-GAAP) was $388.6 million, or $3.74 per diluted share. Excluding similar non-cash items and their tax impact, adjusted net income (non-GAAP) for 2011 was $430.1 million, or $4.15 per diluted share. For a description and a reconciliation of net income (GAAP) to adjusted net income (non-GAAP), please see “Supplemental Non-GAAP Financial Measures” below.

EBITDAX was $1,475.6 million in 2012, an increase of 16% from $1,275.2 million in 2011. For a description and a reconciliation of net income (GAAP) to EBITDAX (non-GAAP), please see “Supplemental Non-GAAP Financial Measures” below.

Oil and natural gas sales from continuing operations for 2012 increased 12% when compared to 2011. This increase was attributable to a 27% increase in production from continuing operations in 2012 compared to 2011, which was partially offset by a 34% decrease in the Company’s unhedged realized natural gas price and a 4% decrease in the Company’s unhedged realized oil price. Oil and natural gas production expense from continuing operations for 2012, including oil and natural gas taxes, totaled $343.7 million, or $12.29 per barrel of oil equivalent (“Boe”), a 3% decrease per Boe from 2011. This decrease was due primarily to lower oil and natural gas taxes, which averaged $5.39 per Boe in 2012 as compared to $5.96 per Boe in 2011. The decrease in oil and natural gas taxes per Boe over 2011 was primarily due to lower realized oil and natural gas prices.

Depreciation, depletion and amortization expense (“DD&A”) from continuing operations for 2012 totaled $575.1 million, or $20.56 per Boe, a 13% increase per Boe from 2011.

General and administrative expense (“G&A”) from continuing operations for 2012 totaled $133.8 million, or $4.79 per Boe, as compared to $98.5 million, or $4.48 per Boe, in 2011. Cash G&A for 2012 totaled $103.9 million and stock-based compensation (non-cash) totaled $29.9 million. The increase in per Boe expense for 2012 over 2011 was primarily due to a 36% increase in absolute G&A expenses reflecting increased staffing across the Company, and was partially offset by a 27% increase in production from continuing operations.

The Company’s cash flow from operating activities (GAAP) was $1,237.5 million for 2012, as compared to $1,199.5 million for 2011, an increase of 3%. Adjusted cash flows (non-GAAP), which are cash flows from operating activities (GAAP) adjusted for settlements on derivatives not designated as hedges, were $1,261.0 million for 2012, as compared to $1,114.6 million for 2011, an increase of 13%. For a description of the use of adjusted cash flows (non-GAAP) and for a reconciliation of cash flows from operating activities (GAAP) to adjusted cash flows (non-GAAP), please see “Supplemental Non-GAAP Financial Measures” below.

In 2012, the Company collected net cash receipts on derivatives not designated as hedges of $23.5 million and the non-cash unrealized mark-to-market gain on derivatives not designated as hedges was $103.9 million. In comparison, the Company made net cash payments of $84.9 million on derivatives not designated as hedges and reported a $61.5 million non-cash unrealized mark-to-market gain on derivatives not designated as hedges in 2011.

Unaudited

The following tables provide information that the Company believes may be useful to investors who follow the practice of some industry analysts who adjust reported company net income and cash flows from operating activities to exclude certain non-cash items.

EBITDAX

EBITDAX (as defined below) is presented herein, and reconciled from the generally accepted accounting principles ("GAAP") measure of net income because of its wide acceptance by the investment community as a financial indicator of a company's ability to internally fund exploration and development activities.

We define EBITDAX as net income, plus (1) exploration and abandonments expense, (2) depreciation, depletion and amortization expense, (3) accretion expense, (4) impairments of long-lived assets, (5) non-cash stock-based compensation expense, (6) bad debt expense, (7) unrealized gain on derivatives not designated as hedges, (8) (gain) loss on sale of assets, net, (9) interest expense, (10) federal and state income taxes on continuing operations and (11) similar items listed above that are presented in discontinued operations. EBITDAX is not a measure of net income or cash flows as determined by GAAP.

Our EBITDAX measure (which includes continuing and discontinued operations) provides additional information which may be used to better understand our operations. EBITDAX is one of several metrics that we use as a supplemental financial measurement in the evaluation of our business and should not be considered as an alternative to, or more meaningful than, net income, as an indicator of our operating performance. Certain items excluded from EBITDAX are significant components in understanding and assessing a company's financial performance, such as a company's cost of capital and tax structure, as well as the historic cost of depreciable assets, none of which are components of EBITDAX. EBITDAX, as used by us, may not be comparable to similarly titled measures reported by other companies. We believe that EBITDAX is a widely followed measure of operating performance and is one of many metrics used by our management team, and by other users, of our consolidated financial statements. For example, EBITDAX can be used to assess our operating performance and return on capital in comparison to other independent exploration and production companies without regard to financial or capital structure, and to assess the financial performance of our assets and our company without regard to capital structure or historical cost basis.
