Exhibit 99.1 TO BUSINESS AND ENERGY EDITORS: Oceaneering Announces 12% Sequential Improvement in Quarterly Earnings HOUSTON, Nov. 10 /PRNewswire-FirstCall/ -- Oceaneering International, Inc. (NYSE: OII) today reported earnings of $0.37 per common share for the third quarter ended September 30, 2003; on revenue of $172.8 million, Oceaneering generated net income of $9.0 million. For the second quarter of 2003, Oceaneering reported earnings per share of $0.33, or net income of $8.1 million, on revenue of $163.8 million. The 12% increase in earnings over the second quarter was the result of improved profit contributions by the Inspection, Subsea Projects, and Advanced Technologies business segments. Summary of Results (in thousands, except per share amounts) Three months ended Nine months ended Sept. 30, June 30, Sept. 30, 2003 2002 2003 2003 2002 Revenue $172,754 $130,607 $163,761 $477,184 $411,006 Gross Margin $30,372 $30,079 $ 28,226 $82,761 $87,676 Operating Income $16,050 $17,494 $14,743 $42,250 $52,702 Net Income $9,038 $11,909 $8,086 $23,159 $31,199 Diluted Earnings Per Share $0.37 $0.48 $0.33 $0.95 $1.27 Weighted Average Number of Diluted Shares 24,488 24,802 24,283 24,424 24,638 Oceaneering had third quarter 2002 revenue of $130.6 million and net income of $11.9 million, or $0.48 per share. On comparable gross margin, the year-over-year decline in quarterly net income was attributable to a higher effective tax rate than in 2002. The 2002 tax rate was lower due to the realization of previously unrecognized foreign tax credits and favorable finalizations of tax positions related to Oceaneering's international oilfield vessel and diving operations exited in 2000. John Huff, Chairman and Chief Executive Officer, stated, "We are pleased with the results for the quarter, which were within our earnings guidance range. Gross margin from each of our business segments, with the exception of Subsea Products, continued to improve in the third quarter, despite a challenging market environment for oilfield services and products in general. "When compared to the second quarter of this year, gross margin contribution from our Inspection business increased due to higher service sales, particularly in Europe, and an overall increase in gross margin percentage as we improved the efficiency of our combined operations. Subsea Projects gross margin improved on the strength of a higher profit contribution from our diving operations. Advanced Technologies had a great quarter, setting a new revenue record while achieving near record gross margin performance on the strength of additional work performed for the U.S. Navy. Gross margins from our Remotely Operated Vehicle (ROV) and Mobile Offshore Production Systems segments were comparable to the second quarter. "Subsea Products gross margin declined and backlog dropped to $17 million, down from $26 million at the end of the second quarter. Our relatively low level of backlog remains attributable to delayed umbilical orders and we continue to expect our backlog to be higher by the end of this year. We are continuing our efforts to locate a suitable facility to expand our U.S. umbilical plant manufacturing capacity and product mix. "Operating activities continued to provide strong cash flow during the third quarter. Our capital expenditures, including acquisitions, were $25 million. Our cash balance at quarter's end was $21 million and we had $85 million of funds available under our $100 million credit facility. "We are projecting earnings per share of approximately $0.25 for the fourth quarter. Consequently, our current 2003 EPS outlook is $1.20. This forecast reflects lower profit contributions in the last half of 2003 from our Subsea Products and Subsea Projects business segments as a result of delays in contract awards and reduced market demand for these operations. "Considering the reduced levels of activity in the offshore energy services and products markets, we are modifying our estimate of 2004 EPS to approximately $1.40. This estimate is predicated on improving demand for our subsea products and a continuation of current market conditions or similar demand trends for our other business segments. We expect earnings from our existing business operations to be augmented by cost efficiencies achieved from ongoing efforts, the three product acquisitions we have made in 2003, and the planned expansion of our umbilical manufacturing plants. Profit contributions from our announced U.S. and Brazilian steel tube capabilities are expected by the third quarter of 2004. This $1.40 per share does not include any other acquisitions or capital equipment additions. "We continue to be bullish about the earnings leverage of our niche market and deepwater focus. Should a substantive recovery in market demand occur, particularly for our ROV and Subsea Projects, we will be able to utilize our excess capacity and operating leverage to increase our earnings. However, we are not satisfied with the status quo and will not simply wait for the market to recover. In 2003 we proved our ability to make accretive acquisitions. We remain committed to use our financial strength to make accretive investments that will expand and augment our existing operations in 2004. "During the quarter we announced an agreement to invest approximately $45 million, subject to certain conditions, in the ownership of the Medusa Spar, a floating production facility located in the Gulf of Mexico. It is our belief that the closing of this transaction will occur by the end of this year, and this investment will result in an upward revision to our 2004 EPS outlook."
