NEWS RELEASE

Abraxas Reports Second Quarter 2011 Results

SAN ANTONIO (August 9, 2011) – Abraxas Petroleum Corporation (NASDAQ:AXAS) today reported financial and operating results for the three and six months ended June 30, 2011.

Financial and Operating Results

Including Abraxas’ equity interest in Blue Eagle’s production, the three months ended June 30, 2011 resulted in:

·   Production of 349.9 MBoe (3,845 Boepd), a 5% increase over Q1 2011, of which 49% was oil or natural gas liquids.

The three months ended June 30, 2011 resulted in:

·   Production of 308.4 MBoe (3,389 Boepd), excluding Abraxas’ equity interest in Blue Eagle’s production;

·   Revenue of $17.0 million;

·   EBITDA(a) of $7.4 million;

·   Discretionary cash flow(a) of $5.6 million;

·   Net income of $8.9 million, or $0.10 per share; and

·   Adjusted net income(a) of $978,000, or $0.01 per share.

(a)   See reconciliation of non-GAAP financial measures below.

Net income for the quarter ended June 30, 2011 was $8.9 million, or $0.10 per share, compared to net income of $5.3 million, or $0.07 per share, for the same period in 2010.  Adjusted net income, excluding unrealized gains on derivative contracts, for the quarter ended June 30, 2011 was $978,000, or $0.01 per share, compared to adjusted net loss, excluding unrealized gains on derivative contracts, of $641,000, or $0.01 per share, for the same period in 2010.

Unrealized gains or losses on derivative contracts are based on mark-to-market valuations which are non-cash in nature and may fluctuate drastically period to period.  As commodity prices fluctuate, these derivative contracts are valued against current market prices at the end of each reporting period in accordance with Accounting Standards Codification (“ASC”) 815, “Derivatives and Hedging,” as amended and interpreted, and require Abraxas to either record an unrealized gain or loss based on the calculated value difference from the previous period-end valuation.  As an example, oil prices on June 30, 2011 were $95.42 per barrel compared to oil prices on March 31, 2011 of $106.72 per barrel; therefore, the mark-to-market valuation decreased considerably period to period which resulted in a decreased liability and an unrealized gain.

Weather Related Downtime

During the second quarter of 2011, Abraxas experienced above normal weather related downtime, principally in the Rocky Mountain region due to severe flooding as a result of the extreme winter weather and heavy snowfall, which reduced production during the quarter by approximately 100 barrels of oil equivalent per day.

Comments

“During the 2nd quarter, we increased production 5% over the 1st quarter despite weather downtime.  We look forward to continued quarterly production growth which should result in increased revenue and cash flow for the foreseeable future,” commented Bob Watson, Abraxas’ President and CEO.

       RECONCILIATION OF NON-GAAP FINANCIAL MEASURES

To fully assess Abraxas’ operating results, management believes that, although not prescribed under generally accepted accounting principles ("GAAP"), discretionary cash flow and EBITDA are appropriate measures of Abraxas' ability to satisfy capital expenditure obligations and working capital requirements.  Discretionary cash flow and EBITDA are non-GAAP financial measures as defined under SEC rules. Abraxas' discretionary cash flow and EBITDA should not be considered in isolation or as a substitute for other financial measurements prepared in accordance with GAAP or as a measure of the Company's profitability or liquidity.  As discretionary cash flow and EBITDA exclude some, but not all items that affect net income and may vary among companies, the discretionary cash flow and EBITDA presented below may not be comparable to similarly titled measures of other companies.  Management believes that operating income calculated in accordance with GAAP is the most directly comparable measure to discretionary cash flow and EBITDA; therefore, operating income is utilized as the starting point for these reconciliations.

Discretionary cash flow is defined as operating income plus depreciation, depletion and amortization expenses, non-cash expenses and impairments, cash portion of other income (expense) less cash interest. The following table provides a reconciliation of discretionary cash flow to operating income for the periods presented.

Discretionary cash flow	$	5,588		$	4,990		$	10,276		$	9,886

EBITDA is defined as net income (loss) plus interest expense, depreciation, depletion and amortization expenses, deferred income taxes and other non-cash items.  The following table provides a reconciliation of EBITDA to operating income for the periods presented – see consolidated statements of operations for a reconciliation of net income (loss) to operating income.

This release also includes a discussion of “adjusted net income (loss), excluding certain non-cash items,” which is a non-GAAP financial measure as defined under SEC rules.  The following table provides a reconciliation of adjusted net income (loss), excluding change in unrealized derivative fair value, to net income (loss) for the periods presented.  Management believes that net income (loss) calculated in accordance with GAAP is the most directly comparable measure to adjusted net income (loss), excluding certain non-cash items.
