EXHIBIT 99.1 NUEVO ENERGY REPORTS SECOND QUARTER EARNINGS; REDEEMED $160 MILLION OF 9 1/2% LONG-TERM DEBT Nuevo Energy Company (NYSE: NEV) today reported net income of $7.4 million, or $0.38 per diluted share in the second quarter 2003, compared to $16.6 million, or $0.96 per diluted share in the second quarter 2002. Income from continuing operations for the second quarter 2003 was $6.6 million, or $0.34 per diluted share versus $14.6 million, or $0.84 per diluted share in the year ago period. The second quarter 2003 results include a $2.7 million after-tax ($0.14 per diluted share) gain on disposition of properties and a $6.7 million after-tax ($0.34 per diluted share) loss on early extinguishment of debt. The comparable item in the second quarter 2002 was a $9.1 million after-tax ($0.53 per diluted share) gain on disposition of properties. Net cash provided by operating activities was $37.9 million in the second quarter 2003 compared to $16.7 million in the same period in 2002. Discretionary cash flow, a non-GAAP financial measure, was $37.2 million in the second quarter 2003 compared to $33.2 million in the second quarter 2002. "On top of strong financial results for the quarter we significantly improved our capitalization by redeeming approximately $160 million of high cost debt," commented Jim Payne, Chairman, President and CEO. "We have made great strides in improving our balance sheet, and in a relatively short time period we reduced our debt to capital to 48% at June 30, 2003 versus 62% at December 31, 2001. We will continue to pursue our disciplined financial and operating strategy." PRODUCTION AND PRICES Total production from continuing operations was 48.2 thousand barrels of oil equivalent (MBOE) per day in the second quarter 2003 compared to 46.0 MBOE per day in the comparable period in 2002. Production from our discontinued operations and assets held for sale was 1.2 MBOE per day in the second quarter 2003 and 5.0 MBOE per day in the second quarter 2002. Crude oil production of 42.1 thousand barrels (MBbls) per day was slightly higher than 41.3 MBbls per day in the comparable period in 2002 due to increased production from the Point Pedernales Field offshore California and production from our September 2002 West Texas acquisition. The realized crude oil price increased 14% to $21.09 per barrel in the second quarter 2003 versus $18.47 per barrel in the year ago period. Included in the realized crude oil prices are hedging losses of $1.59 per barrel for the second quarter 2003 and $0.58 per barrel in the comparable period a year ago. Nuevo's second quarter 2003 natural gas production increased 30% to 36.4 million cubic feet (MMcf) per day from 28.1 MMcf per day in the second quarter 2002 due to production from our West Texas acquisition which more than offset lower production in California. Nuevo's realized natural gas price increased 31% to $4.06 per thousand cubic feet (Mcf) in the second quarter 2003 compared to $3.10 per Mcf in the year ago period. Included in the realized gas price is a hedging loss of $0.20 per Mcf in the second quarter 2003. No gas was hedged in the 2002 period. DRILLING UPDATE The Diatomite drilling program at the Cymric and Midway-Sunset Fields onshore California has been completed and the steaming of these new wells and surrounding wells has commenced. As a result of this activity, production at these fields should average 1,500 barrels per day higher in the second half of 2003 compared to the second quarter. The Cymric and Midway-Sunset Fields represent about 49% of Nuevo's California production. Year-to-date, five wells have been drilled and completed at the Pakenham Field in West Texas and production has increased 26% to 24 MMcfe (million cubic feet of gas equivalent) per day from 19 MMcfe per day at the time of acquisition. For the balance of 2003, Nuevo will drill an additional five wells at the Pakenham Field including a deep Ellenberger test which was spudded in July. COSTS AND EXPENSES Total costs and expenses in the second quarter 2003 were $61.6 million versus $42.0 million in the year ago period. Excluding the gain on disposition of properties and steam costs, total costs and expenses were $53.4 million in the second quarter 2003 compared to $49.2 in the second quarter 2002. Lease operating expenses represented a significant portion of the quarter-over-quarter increase in total costs due to natural gas costs which increased 61% to $5.03 per Mcf versus the second quarter 2002. Natural gas is used to generate steam which in turn facilitates production of heavy oil in California. Excluding the natural gas cost, lease operating expense was $29.5 million in the second quarter 2003 versus $24.3 million in the comparable period in 2002. The main increase quarter-over-quarter is attributable to increased major maintenance and workover activity. Nuevo continues to maintain cost discipline over other controllable lease operating expenses. General and administrative costs also declined significantly to $6.3 million in the second quarter 2003 versus $7.2 million in the same period in 2002 mainly due to lower outsourcing costs. DD&A of $17.7 million was up $0.2 million from the second quarter of 2002, but included $2.4 million of accretion expense required by SFAS No. 143. DD&A expense averaged $4.04 per barrel oil equivalent (BOE) in the second quarter 2003 compared to $4.17 per BOE in the year ago period. Interest expense was $9.0 million in the second quarter 2003, a $0.2 million decline versus the year ago period. Due to the redemption of the 9 1/2% Notes with cash on hand supplemented by low cost bank debt, subsequent quarters will reflect a substantial interest expense reduction. During the second quarter 2003, Nuevo terminated two remaining interest rate swaps and received $4.1 million of cash which will be amortized into income over the life of the Notes. CAPITAL EXPENDITURES Capital expenditures in the second quarter 2003 were $15.7 million, primarily spent on our Cymric, Belridge and Pakenham fields. Capital expenditures for the first half 2003 were $32.6 million compared to $30.6 million in the comparable period in 2002. Our 2003 capital program will be in the range of $65 - $70 million. BALANCE SHEET In the second quarter 2003, Nuevo redeemed $157.2 million of 9 1/2% Senior Subordinated Notes due 2008 and $2.4 million of 9 1/2% Senior Subordinated Notes due 2006. At June 30, 2003, total debt outstanding was $316.2 million versus $438.3 million at year-end 2002. At the end of the second quarter 2003, Nuevo's debt to capital ratio as defined in our credit agreement declined to 48% compared to 57% at year-end 2002. The fixed charge coverage ratio improved to 5.0 times for the four quarters ending June 30, 2003 versus 2.6 times in the comparable period a year ago. As of June 30, 2003, Nuevo had assets held for sale with a book value of approximately $48.2 million related to certain California real estate and a non-core oil field.

NUEVO ENERGY COMPANY RECONCILIATION OF NON-GAAP FINANCIAL MEASURES (IN THOUSANDS) <Table> <Caption> Three Months Ended June 30, Six Months Ended June 30, 2003 2002 2003 2002 ----------- ------------ ----------- ---------- </Table> Discretionary cash flow represents net cash provided by operating activities before changes in assets and liabilities and exploration expense, less interest capitalized. Discretionary cash flow is presented because management believes it is a useful adjunct to net cash provided by operating activities under accounting principles generally accepted in the United States (GAAP). Management believes that discretionary cash flow is widely accepted as a financial indicator of an oil and gas company's ability to generate cash which is used to internally fund exploration and development activities, service debt and pay dividends. This measure is widely used by investors and professional research analysts in the valuation, comparison, rating and investment recommendations of companies within the oil and gas exploration and production industry. Discretionary cash flow is not a measure of financial performance under GAAP and should not be considered as an alternative to cash flow from operating, investing, or financing activities as an indicator of cash flow, or as a measure of liquidity, or as an alternative to net income. <Table> DISCRETIONARY CASH FLOW Net cash provided by operating activities $ 37,949 $ 16,686 $ 85,073 $ 29,006 Working capital changes, net of non-cash (787) 16,546 (3,567) 27,313 Exploration costs excluding dry hole costs 602 453 1,103 1,421 Interest capitalized (551) (439) (1,060) (888) -------- -------- -------- -------- DISCRETIONARY CASH FLOW $ 37,213 $ 33,246 $ 81,549 $ 56,852 ======== ======== ======== ======== </Table> Total costs and expenses excluding the gain on the disposition of properties and steam costs is a non-GAAP financial measure. The Company believes that this measure more fully reflects inherent costs and expenses of our business and is useful in evaluating our operational trends and performance relative to other exploration and production companies. <Table> TOTAL COSTS AND EXPENSES EXCLUDING GAIN ON DISPOSITION OF PROPERTIES AND STEAM COSTS $ 53,427 $ 49,192 $ 106,944 $ 101,503 Loss (gain) on disposition of properties (4,457) (15,326) (4,457) (15,326) Steam costs 12,585 8,114 24,371 14,842 -------- -------- --------- --------- TOTAL COSTS AND EXPENSES $ 61,555 $ 41,980 $ 126,858 $ 101,019 ======== ======== ========= ========= </Table> Lease operating expenses excluding steam costs is a non-GAAP financial measure. Nuevo's heavy oil production in California is produced using thermal techniques in which natural gas is used to generate steam which facilitates the production of heavy oil. Over time, natural gas prices exhibit a high degree of price volatility. Due to commodity price volatility and specialized thermal techniques used to produce heavy California oil, the Company believes that lease operating expenses excluding steam costs are more comparable to lease operating expenses incurred by the majority of exploration and production companies. <Table> LEASE OPERATING EXPENSES EXCLUDING STEAM COSTS $29,521 $24,300 $57,065 $52,198 Steam costs 12,585 8,114 24,371 14,842 ------- ------- ------- ------- LEASE OPERATING EXPENSE $42,106 $32,414 $81,436 $67,040 ======= ======= ======= ======= </Table>
