Contango Reports Third Quarter Earnings

    HOUSTON--(BUSINESS WIRE)--May 12, 2004--Contango Oil & Gas Company
(AMEX:MCF) reported net income attributable to common stock for the
three months ended March 31, 2004 of $1.2 million, or $0.11 per basic
share and $0.09 per diluted share, compared to a net loss attributable
to common stock for the three months ended March 31, 2003 of $1.9
million, or $0.21 per basic and diluted share. Natural gas and oil
sales for the three months ended March 31, 2004 were $6.6 million.
Natural gas and oil sales for the three months ended March 31, 2003
were $10.0 million. EBITDAX was $5.6 million for the three months
ended March 31, 2004, up from EBITDAX for the three months ended March
31, 2003 of $3.0 million.
    Net income attributable to common stock for the nine months ended
March 31, 2004 was $8.2 million, or $0.83 per basic share and $0.67
per diluted share, compared to a net loss attributable to common stock
for the nine months ended March 31, 2003 of $6.1 million, or $0.68 per
basic and diluted share. Natural gas and oil sales for the nine months
ended March 31, 2004 were $20.8 million. Natural gas and oil sales for
the nine months ended March 31, 2003 were $24.8 million. EBITDAX was
$24.0 million for the nine months ended March 31, 2004, up from
EBITDAX for the nine months ended March 31, 2003 of $13.8 million.
    Kenneth R. Peak, Contango's chairman and chief executive officer,
said, "This quarter continues Contango's impressive financial
performance. For the nine months, we earned $8.2 million in net after
tax income available to our common stockholders and generated $24.0
million in EBITDAX on $21.0 million of revenues. We have a strong
balance sheet with $2.5 million of debt currently outstanding and
$21.0 million of unused bank loan capacity. Near record commodity
prices, together with our low cost structure, are enabling us to
continue to generate $1.5 to $2.0 million of monthly EBITDAX despite
recent property sales and normal production declines in existing
fields."
    Mr. Peak continued, "Our capex budget for exploration drilling to
replace and grow our reserves is ramping up with two wells currently
drilling and another two wells expected to spud within the next month.
In the central Gulf of Mexico lease sale held in March 2004, we were
the apparent high bidder on 24 blocks, 18 of which have been awarded.
For the remainder of calendar year 2004, we expect to drill about 15
to 20 exploration wells, three to five of which we expect will be deep
shelf offshore Gulf of Mexico wells in which our partially owned
subsidiaries Republic Exploration and Contango Offshore Exploration
will be fully carried."

EBITDAX (1)         $5,584,137   $2,990,829  $23,987,358  $13,768,519

(1) EBITDAX represents earnings before interest, income taxes,
depreciation, depletion and amortization, impairment expenses,
exploration expenses, including gain (loss) from hedging activities
and sale of assets. The Company has reported EBITDAX because it
believes 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. The Company believes 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 the Company's 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
the Company's statements of cash flows. Investors should carefully
consider the specific items included in the Company's computation of
EBITDAX. While the Company has disclosed its EBITDAX to permit a more
complete comparative analysis of its operating performance and debt
servicing ability relative to other companies, investors should be
cautioned that EBITDAX as reported by the Company 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.

    A reconciliation of EBITDAX to income (loss) from operations for
the periods indicated is presented below.
