The market indicators and company estimates may differ considerably from the company's actual results to be reported on April 27, 2005. Highlights - First Quarter 2005 vs. Fourth Quarter 2004 -- Exploration and Production -- Higher crude oil prices. -- Lower U.S. natural gas prices. -- Daily production close to prior quarter levels. -- Refining and Marketing -- Higher U.S. refining margins. -- Lower international refining margins. -- Significantly lower worldwide marketing margins. -- Capacity utilization rate in the low 90-percent range. -- Increased turnaround activity and costs. -- LUKOIL Investment -- Ownership of 11.3 percent at quarter end. -- Midstream/Chemicals -- Lower Midstream natural gas liquids prices. -- Restructure of DEFS. -- Higher Chemicals results. -- Corporate -- Debt balance of $14.0 billion. Exploration and Production The table below provides market price indicators for crude oil and natural gas. The company's actual crude oil and natural gas price realizations may vary from these market indicators due to quality and location differentials, as well as the effect of pricing lags. Market Indicators 1Q 2005 4Q 2004 1Q 2005 vs. 1Q 2004 4Q 2004 - ---------------------------------------------------------------------- Dated Brent ($/bbl) $47.50 44.00 3.50 31.95 - ---------------------------------------------------------------------- WTI ($/bbl) 49.70 48.29 1.41 35.23 - ---------------------------------------------------------------------- ANS USWC ($/bbl) 44.86 42.61 2.25 34.14 - ---------------------------------------------------------------------- Henry Hub first of month ($/mcf) 6.27 7.07 (0.80) 5.69 - ---------------------------------------------------------------------- Source: Platts First-quarter production on a barrel-of-oil equivalent basis, including Syncrude, is expected to be close to that of the previous quarter. Greater output in Venezuela and China is expected to be offset by the impact of unscheduled maintenance in Canada, and reduced volumes in the United Kingdom and Norway. Full-year production, including Syncrude, is now expected to be approximately 3 percent higher than the amount produced in 2004, primarily due to unscheduled downtime and maintenance at Prudhoe Bay and elsewhere in Alaska. This excludes the impact of our equity investment in LUKOIL. First-quarter exploration expenses are expected to be lower than those of the prior quarter. Refining and Marketing The table below provides market indicators for regions where the company has significant refining operations. The Weighted U.S. 3:2:1 margin is based on the geographical location and capacity of ConocoPhillips' U.S. refineries. Realized refining margins may differ due to the company's specific locations, configurations, crude oil slates or operating conditions. In addition, the company's refining configuration generally yields somewhat higher distillate volumes and lower gasoline volumes than those implied by the market indicators shown below. Market Indicators 1Q 2005 4Q 2004 1Q 2005 vs. 1Q 2004 4Q 2004 - ---------------------------------------------------------------------- Refining Margins ($/bbl) - ---------------------------------------------------------------------- East Coast WTI 3:2:1 $6.40 5.73 0.67 6.87 - ---------------------------------------------------------------------- Gulf Coast WTI 3:2:1 6.37 4.09 2.28 6.36 - ---------------------------------------------------------------------- Mid-Continent WTI 3:2:1 7.92 5.52 2.40 6.91 - ---------------------------------------------------------------------- West Coast ANS 3:2:1 19.61 17.25 2.36 16.10 - ---------------------------------------------------------------------- Weighted U.S. 3:2:1 9.24 7.24 2.00 8.39 - ---------------------------------------------------------------------- NW Europe Dated Brent 3:1:2 11.14 15.24 (4.10) 7.78 - ---------------------------------------------------------------------- WTI/Maya differential (trading month) 17.08 15.99 1.09 9.36 - ---------------------------------------------------------------------- U.S. Wholesale Gasoline Marketing 0.04 1.97 (1.93) 0.69 - ---------------------------------------------------------------------- Source: Platts U.S. refining margins for the first quarter are expected to be higher than those of the fourth quarter, while international refining margins are expected to be lower, as indicated in the table above. Refining margins should continue to benefit from increased heavy-light differentials; however, high crude costs continue to negatively impact segment earnings due to fixed price products that do not necessarily move with the price of crude. These net refining margin improvements are expected to be offset by significantly lower worldwide marketing margins and increased turnaround activity. This increased turnaround activity is expected to reduce processed input and clean product yields. The company's average crude oil refining capacity utilization rate for the first quarter is expected to be in the low 90-percent range, down from the prior quarter. First quarter turnaround costs are expected to be approximately $120 million before-tax. Midstream/Chemicals In connection with the previously announced restructuring of ConocoPhillips' ownership in Duke Energy Field Services (DEFS), the company expects to recognize net after-tax benefits of approximately $290 million, mainly resulting from DEFS' sale of TEPPCO Partners, L.P. As of the end of the first quarter, ConocoPhillips' interest in DEFS remained at 30.3 percent. Additional transfers related to the restructuring are expected to occur in the second quarter of 2005, subject to regulatory approvals. The Chemicals segment results are expected to be higher due to improved olefins and polyolefins margins. Corporate The company's expected debt balance at the end of the first quarter is $14.0 billion. In addition, the average diluted shares outstanding during the first quarter are expected to be 711 million shares.
