EXHIBIT 99.1 For further information contact John S. Weatherly, CFO 1-800-451-1294 FOR IMMEDIATE RELEASE CALLON PETROLEUM COMPANY REPORTS FIRST QUARTER RESULTS Natchez, MS (May 13, 2003)--Callon Petroleum Company (NYSE: CPE/CPE.PrA) today reported its results of operations for the quarter ended March 31, 2003. For the first quarter of 2003 the company reported net income of $1,382,000, or earnings of $0.08 per diluted share after the cumulative effect of change in accounting principle related to Statement of Financial Accounting Standards (SFAS) No.143 ("Accounting for Asset Retirement Obligations"). This compares to the 2002 first quarter net loss of $2,454,000, or a loss of $0.21 per share on a diluted basis. On January 1, 2003, the company adopted SFAS No. 143, which required companies to record the fair value of a liability for legal obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. As a result, the impact of adopting the statement resulted in a gain of $181,000, net of tax, which was reported as the cumulative effect of change in accounting principle. Net cash flow provided by operating activities before changes in operating assets and liabilities for the first quarter of 2003 was $12.2 million, or $0.83 per diluted share. The schedule below provides for a reconciliation of net cash flow provided by operating activities to net cash flow provided by operating activities before changes in operating assets and liabilities. During the first three months of 2003, average daily production, as well as prices realized for crude oil and natural gas, increased when compared with the same period of last year. Operating results for the three-month period ended March 31, 2003 include oil and gas sales of $21.3 million from average daily production of 41.1 million cubic feet of natural gas equivalent per day (MMcfe/d). This corresponds to sales of $11.1 million from average daily production of 37.3 MMcfe/d during the same period of 2002. The average price per thousand cubic feet of natural gas increased to $5.79 compared to $2.34 during the same period a year earlier, while the average price per barrel of oil increased to $31.32 compared to $18.65 during the first quarter of 2002. The financial and other statistical guidance presented during the company's conference call will be available on the company's homepage. In addition, any reconciliation required pursuant to Regulation G of the Securities Exchange Act of 1934 will also be available on the company's homepage.
