EXHIBIT 99.1 NEWS RELEASE RANGE NET INCOME RISES TO $9.5 MILLION FORT WORTH, TEXAS, MAY 6, 2003...RANGE RESOURCES CORPORATION (NYSE: RRC) today reported first quarter results. Revenues in the quarter reached $57.0 million, a 25% increase from the prior-year period. Pretax income totaled $9.1 million, a seven fold increase. Net income rose 120% to $9.5 million. Results benefited from increased production, higher realized prices and a $4.5 million after-tax gain from the cumulative effect of an accounting change, offset by a $7.2 million increase in deferred taxes. Net income per share reached $0.18 ($0.17 fully diluted). Cash flow from operations rose 21% to $32.9 million. Production in the period rose 3% to an average of 154 Mmcfe per day, comprised of 115 Mmcf and 6,479 barrels of oil and liquids. Wellhead prices, after hedging, averaged $3.92 per mcfe, a 19% increase. Gas prices increased 21% to $3.95 per mcf, as oil prices increased 4% to $23.64 per barrel. Hedging decreased average prices by $1.87 per mcfe. Despite a 25% increase in revenues, expenses rose only 8% in the quarter. Direct operating costs increased $3.8 million due to higher production taxes and field costs. Exploration expense fell $2.8 million, primarily due to lower dry-hole costs. Interest expense remained virtually level. Depletion, depreciation and amortization expense increased $2.9 million due to higher volumes and depletion rates along with $1.1 million of accretion expense from the adoption of SFAS 143. General and administrative expenses rose $376,000 as a result of higher personnel costs and professional fees. The income tax provision increased $7.2 million between periods. During the quarter, $4.1 million of tax expense was recorded. In the previous year, a tax benefit of $3.1 million had been recognized. For the remainder of the year, the deferred tax provision should approximate 35% of pretax income. Also noted above, the Company adopted a new accounting standard SFAS 143 "Accounting for Asset Retirement Obligations" on January 1, 2003. This accounting standard requires companies to record a discounted liability in the period in which an asset retirement obligation is incurred and capitalize additional asset cost equal to the amount of the liability. This liability is then accreted to the undiscounted liability each month through DD&A expense. Upon adoption, Range recognized a $37.3 million increase in the carrying values of proved properties, a $21.0 million decrease in accumulated DD&A, a $51.4 million increase in current and non-current liabilities, a $2.4 million decrease in deferred tax assets and a $4.5 million gain, net of tax, as the cumulative effect of adoption of the accounting standard. In the first quarter, $1.1 million of accretion expense was recorded in DD&A expense and similar amounts will be recorded in future quarters. During the quarter, debt increased by $6.7 million due to timing of cash receipts and disbursements. Since quarter-end, debt has fallen $14.5 million. Capital expenditures were funded with 85% of operating cash flow. Stockholders' equity declined $4.1 million during the quarter, as $9.5 million of net income was more than offset by a $15.3 million increase in Other comprehensive loss, reflecting the impact of higher oil and gas futures prices on outstanding hedges at quarter-end. The Company spent $22 million of capital in the period, funding the drilling of 57 (35.1 net) wells and 7 (4.9 net) recompletions. All but 2 (2.0 net) of the drilling and recompletion projects proved productive. By March 31, 29 (19.6 net) of the wells had been placed on production. The remaining wells were in various stages of completion. An additional $6 million was spent on acquiring producing properties and leasehold. Excluding future acquisitions, capital expenditures are projected to total $110 million for the year. Operational results during the quarter exceeded expectations. In the Southwest, production in the Texas Panhandle, West Texas and western Oklahoma is increasing faster than projected. In Appalachia, production is again on projection, after disruptions caused by severe winter weather early in the year. In the Gulf Coast, production is on trend. Ship Shoal 28 #40 was recently placed on production and a recent high rate onshore discovery should go on production late in the second quarter. The benefit of these discovery wells will initially be offset by lower production from the West Cameron 45 #20 well, where remedial work to repair a downhole

mechanical problem is underway. Production in the second quarter is expected to exceed the prior-year period and first quarter 2003 levels. Commenting, John H. Pinkerton, the Company's President, noted, "We were very pleased with first quarter results as revenues, cash flow and earnings approached record levels. Production increased and, based on recent drilling, a further increase is expected in the second quarter. Several new drilling projects were initiated and excellent returns on investment are being achieved. With a solid start to the year, we are on target to meet or exceed our goals in 2003." Thomas J. Edelman, the Company's Chairman, said, "Range continues to make excellent progress. The efforts of the past several years are beginning to bear fruit, and I have every confidence that rapid progress will continue. Charlie Blackburn's election as Chairman of the Board has added a degree of technical expertise I could not provide. I believe his addition will pay significant dividends over the next few years." The Company will host a conference call on Wednesday, May 7 at 2:00 p.m. ET to review its results.

Non-GAAP Financial Measure: Cash flow from operations represents net cash provided by operations before changes in working capital adjusted for certain non-cash stock compensation items. Cash flow from operations is widely accepted as a financial indicator of an oil and gas company's ability to generate cash to internally fund exploration and development activities and to service debt. Cash flow from operations is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flows from operations, investing, or financing activities as an indicator of cash flows, or as a measure of liquidity. A table is included which reconciles net cash provided by operations to cash flow from operations as used in this release. On its website, the Company provides additional comparative information on prior periods. RANGE RESOURCES CORPORATION (NYSE: RRC) is an independent oil and gas company operating in the Permian, Midcontinent, Appalachian and Gulf Coast regions of the United States. - -------------------------------------------------------------------------------- 2003-10 Contact: Rodney Waller, Senior Vice President Karen Giles (817) 870-2601 www.rangeresources.com Except for historical information, statements made in this release, including those relating to future earnings, capital expenditures, production, expenses, and reserve replacement targets are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.
