Cimarex Energy Announces Third-Quarter 2003 Earnings of $0.53 Per Share

    DENVER, Nov. 5 /PRNewswire-FirstCall/ -- Cimarex Energy Co. (NYSE: XEC)
today reported third-quarter 2003 net income of $22.5 million, or $0.53 per
diluted share.  This compares to third-quarter 2002 net income of $9.9
million, or $0.37 per diluted share.
    Revenues from oil and gas sales in the third quarter of 2003 were $77.6
million, compared to $31.5 million in the same period of 2002.  Cash flow from
operations for the third quarter of 2003 was $52.5 million, versus $24.4
million in the same period of 2002.(1)  Revenues and cash flow in the third
quarter of 2003 were positively impacted by a 57 percent increase in
production volumes as well as a 63 percent increase in gas prices and an 18
percent increase in oil prices.
    Total daily production volumes averaged 181 million cubic feet (MMcf)
equivalent during the third quarter of 2003 versus 115 MMcf equivalent a year
earlier.  The increase is principally attributable to the acquisition of Key
Production Company, Inc. on September 30, 2002.  Third quarter 2003 production
rose 5 percent from 172 MMcf equivalent per day in the second quarter.  This
increase is due to the positive drilling results realized so far this year.
The accompanying tables detail quarterly and year-to-date volumes and prices.
    Capital expenditures for exploration and development during the third
quarter of 2003 totaled $44.7 million, up from $20.8 million for the third
quarter 2002.  Increased capital expenditures reflect expansion of the
Company's drilling program.  In the third quarter of 2003, there were 48 gross
(30 net) wells drilled, up from 37 gross (17 net) wells in the second quarter.
    In addition to increasing capital investment, strong cash flow from
operations enabled us to increase our cash balance to $56.9 million as of
September 30, 2003.

    Year-to-Date 2003
    For the first nine months of 2003, Cimarex reported net income of $76.3
million, or $1.81 per diluted share.  This compares to net income in the first
nine months of 2002 of $24.0 million, or $0.90 per share.
    Revenues from oil and gas sales for the first nine months of 2003 were
$241.5 million.  For the same period of 2002, oil and gas sales were $87.5
million.  Cash flow from operations for the nine months ended September 30,
2003 increased to $166.5 million from $65.1 million in the same period of
2002.(1)  The increases reflect 52 percent higher production volumes, 94
percent higher gas prices and 19 percent higher oil prices.
    Capital expenditures for exploration and development during the first nine
months of 2003 were $102.1 million, up from $45.9 million during the first
three quarters of 2002.  For all of 2003, exploration and development
expenditures are currently projected to total $150-$155 million.  We drilled
118 gross (61 net) wells during the first nine months of 2003, realizing a
success rate of 78%.  We expect to drill approximately 60 gross wells in the
last quarter.

       (1) Cash Flow from Operations is a non-GAAP financial measure that
           represents "Net Cash Provided By Operating Activities" adjusted for
           the change in operating assets and liabilities.  See below for a
           reconciliation of the related amounts.

     Management believes that the non-GAAP measure of cash flow from
     operations is useful information for investors because it is used
     internally and is accepted by the investment community as a means of
     measuring the company's ability to fund its capital program.  It is also
     used by professional research analysts in providing investment
     recommendations pertaining to companies in the oil and gas exploration
     and production industry.
