DUNE ENERGY REPORTS THIRD QUARTER 2011 FINANCIAL RESULTS and UPDATES OPERATIONS

Houston, Texas, November 1, 2011—Dune Energy, Inc. (OTCBB:DUNR) today announced results for the third quarter of 2011 and provided an operational update.

Revenue and Production

Revenue from continuing operations for the third quarter totaled $15.1 million as compared with $15.6 million for the third quarter of 2010. Production volumes in the third quarter were 120 Mbbls of oil and .68 Bcf of natural gas, or 1.4 Bcfe. This compares with 148 Mbbls of oil and .93 Bcf of natural gas, or 1.8 Bcfe for the third quarter of 2010. In the third quarter of 2011, the average sales price per barrel of oil was $98.93 and $4.77 per Mcf for natural gas, as compared with $74.92 per barrel and $4.87 per Mcf, respectively for the third quarter of 2010. The primary reasons behind the decrease in revenue were lower production volumes in the third quarter of 2011 versus the third quarter of 2010. Oil volumes decreased 19% and gas volumes decreased 27% from 2010 levels. However, the average price per Mcfe produced was $10.81 in the third quarter of 2011 compared to $8.59 in the third quarter of 2010 or a 26% increase.

Costs and Expenses

Total lease operating expense from continuing operations for the third quarter totaled $6.1 million versus $5.3 million for the third quarter of 2010. Cash G&A expense totaled $2.3 million for the third quarter of 2011 versus $2.1 million for the third quarter of 2010. Interest financing expense was $9.1 million for the third quarter of 2011 versus the $8.8 million of 2010, primarily associated with payment of 10.5% interest on the $300 million of Senior Secured Notes and higher interest rates applicable to the Credit Agreement. We incurred a gain of $.06 million on hedging during the third quarter of 2010 versus no activity in 2011 due to settling all hedge balances in December 2010.

Earnings

Operating loss for the third quarter of 2011 was $.1 million versus a $.03 million operating loss in the third quarter of 2010. Net loss totaled $10.2 million for the third quarter of 2011 and $9.1 million for the third quarter of 2010. Preferred stock dividends were $5.3 million in the third quarter of 2011 versus $6.5 million in the third quarter of 2010. These dividends were paid in kind (PIK) and as such do not represent a cash payment. Net loss per share, both basic and fully diluted, for the quarter was $0.32, based on 48.9 million weighted average shares outstanding as compared with a loss of $.39 per share in the third quarter of 2010 with 40.4 million weighted average shares outstanding. The increased outstanding common shares are associated with the conversion of preferred shares into common shares.

Operational Update

The CNO #1 at Leeville Field, operated by Manti Exploration Operating LLC, was drilled to a total depth of 14,670 feet measured depth and 14,033 true vertical depth. The well encountered 68 feet of pay in three sands. The well has been perforated in the lowermost sand and tested at rates over 4 Mmcfg / day. Production is anticipated to commence in November of 2011 after installation of a flow line. Dune has a 40% interest in the well. See Investor Overview for November, 2011 on our website for more details on operations and plans for the remainder of 2011.
