Cimarex Reports First-Quarter 2008 Earnings of $1.76 per Share

    DENVER, May 6 /PRNewswire-FirstCall/ -- Cimarex Energy Co. (NYSE: XEC) today
reported first-quarter 2008 net income of $149.8 million, or $1.76 per diluted
share. This compares to first-quarter 2007 earnings of $64.6 million, or $0.77
per diluted share.

    Revenues from oil and gas sales in the first quarter of 2008 were $454.4
million, compared to $293.5 million in the same period of 2007. First-quarter
2008 cash flow from operations totaled $334.7 million versus $215.4 million in
the same period of 2007(1).

    The increase in first-quarter 2008 revenues, earnings and cash flow is
primarily a result of higher production and oil and gas prices. First-quarter
2008 gas prices increased 25% to $8.38 per thousand cubic feet (Mcf) and oil
rose 71% to $94.38 per barrel from the same period of 2007.

    First-quarter 2008 daily oil and gas production grew 8% over last year's
first quarter. Gas production in the latest quarter averaged 339.7 million cubic
feet per day, an increase of 5% over the first-quarter 2007 and oil production
grew 16% to an average of 22,757 barrels per day. Growing production reflects
strong results from drilling.

    Capital

    First-quarter 2008 exploration and development capital totaled $307.0
million as compared to $245.5 million in the first quarter of 2007. In the first
quarter of 2008, Cimarex drilled 126 gross (76 net) wells, completing 95% of the
gross wells as producers. Exploration and development capital investment for
2008 is still projected to range from $1.1 - $1.3 billion.

    Outlook

    Second-quarter 2008 production volumes are projected to range between
478-488 MMcfe/d. Full-year 2008 production is projected to be in the range of
475-495 MMcfe/d, or an 8-12% increase over 2007 after adjusting for property
sales.

    Expenses for the remainder of 2008 are expected to fall within the following
ranges:

    Expenses ($/Mcfe):
      Production expense                            $1.20 - $1.30
      Transportation expense                         0.17 -  0.20
      DD&A and ARO accretion                         2.85 -  3.00
      General and administrative expense             0.26 -  0.30
      Production taxes (% of oil and gas revenue)    6.5% -  7.5%

    research analysts in providing investment recommendations pertaining to
    companies in the oil and gas exploration and production industry.
