EXHIBIT 99.1 ==================================================================== [OXY LOGO] NEWS RELEASE OCCIDENTAL PETROLEUM CORPORATION ==================================================================== 10889 Wilshire Boulevard, Los Angeles, California 90024 (310) 208-8800 For Immediate Release: July 22, 2003 OCCIDENTAL PETROLEUM ANNOUNCES SECOND QUARTER 2003 RESULTS ---------------------------------------------------------- LOS ANGELES -- Occidental Petroleum Corporation (NYSE: OXY) announced net income for the second quarter 2003 of $374 million ($0.98 per share), compared with $240 million ($0.64 per share) for the second quarter 2002. In announcing the results, Dr. Ray R. Irani, chairman and chief executive officer, said, "Core earnings of $374 million, or $0.98 per share, were 55 percent higher than the $241 million, or $0.64 per share, the company earned in the second quarter of 2002. Higher oil and gas prices and record production of 544,000 barrels of oil equivalent per day resulted in a 51 percent increase in oil and gas earnings over last year's second quarter. Core earnings of $807 million, or $2.12 per share, for the first half of this year were more than double the $364 million, or $0.97 per share, the company earned in the comparable period last year." OIL AND GAS ----------- Oil and gas segment and core earnings were $637 million for the second quarter 2003, compared with $421 million for the second quarter 2002. The improvement in the second quarter 2003 earnings reflected approximately $200 million from higher worldwide crude oil and natural gas prices, increased sales volumes and lower exploration expense. The second quarter 2003 also included $14 million in after-tax gains on asset sales; partially offset by higher operating costs. CHEMICALS --------- Chemical segment and core earnings were $43 million for the second quarter 2003, compared with $34 million for the second quarter 2002. The second quarter 2003 results reflected higher sales prices for PVC, chlorine and caustic; partially offset by higher energy and raw material costs and lower sales volumes. The second quarter 2003 included a $9-million asset-writedown charge and a $15 million severance charge. OTHER ----- Occidental adopted FASB Interpretation No.46, Consolidation of Variable Interest Entities, during the second quarter 2003 and added $56 million to debt as a result of consolidating its OxyMar joint venture. The debt-to-capitalization ratio was 40 percent at June 30, 2003, the lowest level in over 20 years. SIX-MONTHS RESULTS ------------------ For the first six months of 2003, net income was $699 million ($1.84 per share), compared with $265 million ($0.71 per share) for the first six months of 2002. Core earnings were $807 million for 2003 compared with $364 million for 2002. See the attached schedule for a reconciliation of net income to core earnings. -0- Contacts: Lawrence P.

The second quarter and six-months 2002 amounts include $8 million and $22 million, respectively, of interest income on notes receivable from the Occidental Permian partners. The partnership exercised an option in May 2002 to redeem the sellers' remaining partnership interests in exchange for the outstanding balance on the notes. (b) Excludes U.S. federal income tax charges and credits allocated to the segments and foreign taxes. Oil and gas segment earnings include charges of $8 million in the second quarter of 2003 and credits of $1 million in the second quarter of 2002. Chemical segment earnings include $4 million of credits in the second quarter of 2002. Oil and gas segment earnings for the six months 2003 and 2002 include charges of $7 million and credits of $1 million, respectively. Chemical segment earnings included credits of $8 million for the six months 2002. (c) Includes preferred distributions to the Occidental Permian partners. The second quarter and six-months 2002 amounts include $5 million and $20 million, respectively. This is essentially offset by the interest income from the Occidental Permian partners discussed in (a) above. The partnership exercised an option in May 2002 to redeem the sellers' remaining partnership interests in exchange for the outstanding balance on the notes. (d) Effective January 1, 2003, Occidental implemented SFAS No. 143 - "Accounting for Asset Retirement Obligations." Adoption of this new accounting standard resulted in a cumulative after-tax reduction in net income of $50 million. Also effective January 1, 2003, Occidental implemented the rescission of EITF 98-10, which precludes mark-to-market accounting for all energy-trading contracts that are not derivatives and fair-value accounting for inventories purchased from third parties. Adoption of this accounting change resulted in a cumulative after-tax reduction in net income of $18 million. Effective January 1, 2002, Occidental implemented SFAS No. 142 - "Goodwill and Other Intangible Assets." Adoption of this new accounting standard resulted in a cumulative after-tax reduction in net income of $95 million. 4 SUMMARY OF OPERATING STATISTICS Second Quarter Six Months ------------------- ------------------- 2003 2002 2003 2002 ================================== ======= ======= ======= ======= NET OIL, GAS AND LIQUIDS PRODUCTION PER DAY United States Crude Oil and Liquids (MBBL) California 81 86 79 88 Permian 151 143 147 141 Horn Mountain 19 -- 16 -- Hugoton 3 3 4 3 ------- ------- ------- ------- Total 254 232 246 232 Natural Gas (MMCF) California 252 290 257 298 Hugoton 143 150 143 154 Permian 131 125 125 127 Horn Mountain 15 -- 10 -- ------- ------- ------- ------- Total 541 565 535 579 Latin America Crude Oil (MBBL) Colombia 36 42 37 39 Ecuador 18 12 17 13 ------- ------- ------- ------- Total 54 54 54 52 Middle East and Other Eastern Hemisphere Crude Oil (MBBL) Oman 11 15 12 16 Pakistan 10 9 10 8 Qatar 51 43 49 43 Yemen 35 33 37 40 ------- ------- ------- ------- Total 107 100 108 107 Natural Gas (MMCF) Pakistan 77 50 76 50 BARRELS OF OIL EQUIVALENT (MBOE) Subtotal consolidated subsidiaries 518 489 510 496 Other interests Colombia-minority interest (5) (5) (4) (5) Russia-Occidental net interest 30 28 30 27 Yemen-Occidental net interest 1 -- 2 -- ------- ------- ------- ------- Total worldwide production 544 512 538 518 ======= ======= ======= ======= CAPITAL EXPENDITURES (millions) $ 493 $ 303 $ 791 $ 557 ======= ======= ======= ======= DEPRECIATION, DEPLETION AND AMORTIZATION OF ASSETS (millions) $ 286 $ 253 $ 571 $ 514 ================================== ======= ======= ======= ======= 5 SIGNIFICANT TRANSACTIONS AND EVENTS AFFECTING EARNINGS Occidental's results of operations often include the effects of significant transactions and events affecting earnings that vary widely and unpredictably in nature, timing, and amount. Therefore, management uses a measure called "core earnings", which excludes those items. This non-GAAP measure is not meant to disassociate those items from management's performance, but rather is meant to provide useful information to investors interested in comparing Occidental's earnings performance between periods. Reported earnings are considered representative of management's performance over the long term. Core earnings is not considered to be an alternative to operating income in accordance with generally accepted accounting principles. The following table sets forth the core earnings and significant items affecting earnings for each operating segment and corporate: Second Quarter ------------------------------------------- ($ millions) 2003 EPS 2002 EPS ================================= ======= ======= ======= ======= TOTAL REPORTED EARNINGS $ 374 $ 0.98 $ 240 $ 0.64 ======= ======= ======= ======= Oil and Gas Segment Earnings $ 637 $ 421 No significant items affecting earnings -- -- ------- ------- Segment Core Earnings 637 421 ------- ------- Chemicals Segment Earnings 43 34 No significant items affecting earnings -- -- ------- ------- Segment Core Earnings 43 34 ------- ------- Corporate Results (306) (215) Less: Discontinued operations, net* -- (1) ------- ------- TOTAL CORE EARNINGS $ 374 $ 0.98 $ 241 $ 0.64 ================================= ======= ======= ======= ======= *These amounts are shown after tax. 6 SIGNIFICANT TRANSACTIONS AND EVENTS AFFECTING EARNINGS (continued) Six Months -------------------------------------------- ($ millions) 2003 EPS 2002 EPS ================================= ======= ======= ======= ======= TOTAL REPORTED EARNINGS $ 699 $ 1.84 $ 265 $ 0.71 ======= ======= ======= ======= Oil and Gas Segment Earnings $ 1,364 $ 727 No significant items affecting earnings -- -- ------- ------- Segment Core Earnings 1,364 727 ------- ------- Chemicals Segment Earnings 78 3 No significant items affecting earnings -- -- ------- ------- Segment Core Earnings 78 3 ------- ------- Corporate Results (743) (465) Less: Debt repayment charge (61) -- Tax effect of pre-tax charge 21 -- Discontinued operations, net* -- (4) Changes in accounting principles, net* (68) (95) ------- ------- TOTAL CORE EARNINGS $ 807 $ 2.12 $ 364 $ 0.97 ================================= ======= ======= ======= ======= *These amounts are shown after tax. 7 ITEMS AFFECTING COMPARABILITY OF CORE EARNINGS BETWEEN PERIODS Second Quarter Six Months ------------------- ------------------- ($ millions) 2003 2002 2003 2002 ================================= ======= ======= ======= ======= PRE-TAX INCOME / (EXPENSE) Oil and Gas Gain on sale of GOM assets 1 $ 14 $ -- $ 14 $ -- Exploration asset write-offs -- (33) -- (33) Chemicals Reorganizations/severance (15) -- (15) (14) Equistar equity results -- (4) -- (40) Chlorine derivatives asset impairment (9) -- (9) -- Corporate Environmental remediation (13) -- (13) -- Equity earnings (15) -- (38) -- 1 Net of tax. 8
