Exhibit 99.1 Contango Announces Results of Operations for the Fiscal Year Ended June 30, 2005 HOUSTON--(BUSINESS WIRE)--Sept. 13, 2005--Contango Oil & Gas Company (AMEX:MCF) reported net income attributable to common stock for the year ended June 30, 2005 of $12.0 million, or $0.92 per basic and diluted share, compared to net income attributable to common stock for the year ended June 30, 2004 of $7.1 million, or $0.68 per basic and diluted share. Natural gas and oil sales from continuing and discontinued operations for the year ended June 30, 2005 were $16.3 million, down from $27.6 million for the year ended June 30, 2004. The decrease in revenue was primarily the result of the sale of our south Texas natural gas and oil interests for $50 million, completed in December 2004. EBITDAX was $28.5 million for the year ended June 30, 2005, down from EBITDAX for the year ended June 30, 2004 of $29.0 million. For the three months ended June 30, 2005 Contango had a net loss attributable to common stock of $1.4 million, or $0.16 per basic and diluted share, compared to a net loss attributable to common stock for the three months ended June 30, 2004 of $1.1 million, or $0.09 per basic and diluted share. Natural gas and oil sales from continuing and discontinued operations for the three months ended June 30, 2005 were $1.3 million, down from $6.8 million for the three months ended June 30, 2004. Kenneth R. Peak, Contango's Chairman and Chief Executive Officer, said, "Fiscal-year 2005 was a productive year for us. We sold the majority of our south Texas natural gas and oil properties in December, paid-off all of our bank debt, greatly increased our liquidity, and positioned ourselves strategically by making substantial capital commitments to our Fayetteville Shale prospect area and our two offshore exploration prospects, Eugene Island 10 ("Dutch") and Grand Isle 72 ("Liberty"). We currently have production of approximately 1,860 Mcfe/d and approximately $29 million in cash, cash equivalents, and short-term investments." Mr. Peak continued, "Since its inception in 1999, Contango has primarily been a company focused on south Texas exploration and the generation of offshore prospects that were subsequently sold on a promoted basis to the industry. In the future, we will be a company focused on developing our Fayetteville Shale play in Arkansas, operating certain of our offshore prospects, maintaining our 10% limited partnership interest in our Freeport LNG project, and maturing our investments in alternative energy."

We have reported EBITDAX because we believe EBITDAX is a measure commonly reported and widely used by investors as an indicator of a company's operating performance and ability to incur and service debt. We believe EBITDAX assists investors in comparing a company's performance on a consistent basis without regard to depreciation, depletion and amortization, impairment of natural gas and oil properties and exploration expenses, which can vary significantly depending upon accounting methods. EBITDAX is not a calculation based on U.S. generally accepted accounting principles and should not be considered an alternative to net income (loss) in measuring our performance or used as an exclusive measure of cash flow because it does not consider the impact of working capital growth, capital expenditures, debt principal reductions and other sources and uses of cash, which are disclosed in our statements of cash flows. Investors should carefully consider the specific items included in our computation of EBITDAX. While we have disclosed our EBITDAX to permit a more complete comparative analysis of our operating performance and debt servicing ability relative to other companies, investors should be cautioned that EBITDAX as reported by us may not be comparable in all instances to EBITDAX as reported by other companies. EBITDAX amounts may not be fully available for management's discretionary use, due to requirements to conserve funds for capital expenditures, debt service, preferred stock dividends and other commitments.
