Exhibit 99.1

           Cimarex Reports First-Quarter Earnings of $0.78 Per Share

    DENVER--(BUSINESS WIRE)--May 7, 2003--Cimarex Energy Co.
(NYSE:XEC) today reported that strong oil and gas prices combined with
higher production volumes boosted first-quarter 2003 net income to
$32.7 million, or $0.78 per diluted share. This compares to
first-quarter 2002 net income of $4.3 million, or $0.16 per share.
    Net income for the first quarter of 2003 includes an after-tax
one-time accounting benefit of $1.6 million, or $0.04 per share, from
the required adoption of Statement of Financial Accounting Standard
No. 143 relating to new accounting treatment for future asset
retirement obligations.
    Revenues from first-quarter 2003 oil and gas sales grew 286
percent to $89.8 million, up from $23.2 million during the first
quarter of 2002.
    Cimarex's realized gas price in the first quarter of 2003 was
$5.76 per thousand cubic feet (Mcf), which was 185 percent higher than
a year ago. Oil prices rose 38 percent to $30.14 per barrel. The
significant increase in first-quarter 2003 product prices reflects
tightening supply and demand conditions in oil and gas markets.
Cimarex was un-hedged during the first quarter and remains so.
    Reported daily average gas production increased by 28 percent to
136 million cubic feet (MMcf) and reported oil production rose 257
percent to 7,212 barrels per day. The jump in production volumes
mainly reflects the September 30, 2002, acquisition of Key Production
Company, Inc.
    Cash flow from operations increased more than four-fold to $65.6
million from $15.7 million during the first three months of 2002. See
below a reconciliation of cash flow from operations, a non-GAAP
financial measure that is widely used by analysts and investors as an
important indicator of financial performance in the oil and gas
exploration and production sector.
    Capitalized costs incurred for oil and gas exploration and
development during the first quarter of 2003 totaled $27.6 million, up
from $12.4 million during the same three months of 2002. During the
last quarter, 41 gross wells had been drilled including 33 new
producers and eight dry holes.
    The strong cash flow generated by first-quarter 2003 production
operations also enabled us to further reduce our debt by $27.0 million
to $5.0 million as of March 31, 2003.
