    ConocoPhillips (NYSE:COP) today reported second-quarter net income
of $3,138 million, or $2.21 per share, compared with $2,075 million,
or $1.48 per share, for the same quarter in 2004. Total revenues were
$42.6 billion, versus $31.9 billion a year ago.
    Income from continuing operations for the second quarter was
$3,131 million, or $2.21 per share, compared with $2,013 million, or
$1.44 per share, for the same period a year ago.
    "We had a strong quarter," said Jim Mulva, chairman and chief
executive officer. "Upstream, we ran as expected. The total company
produced 1.76 million BOE per day, including 1.54 million BOE per day
from our Exploration and Production segment and an estimated 0.22
million BOE per day from our LUKOIL Investment segment. At the same
time, we completed planned and unplanned maintenance in our E&P
business and finalized the formation of the Naryanmarneftegaz joint
venture to develop resources in the Timan-Pechora region of Russia.
    "Downstream benefited from a strong market environment in
refining, partially offset by narrowing light-heavy differentials.
Worldwide crude oil capacity utilization was at 97 percent, as
expected, with our U.S. refining system running near stated capacity.
In addition, worldwide marketing margins improved over the previous
quarter.
    "Our financial position continues to improve, and our return on
capital employed remains strong and competitive. We ended the quarter
with a debt-to-capital ratio of 22 percent. During the quarter, we
generated $2.8 billion in cash from operations, invested $3.1 billion
in capital projects and investments, paid $432 million in dividends
and repurchased $382 million of ConocoPhillips common stock. In
addition, the previously announced 24 percent dividend increase and
2-for-1 stock split occurred during the second quarter."
    For the first six months of 2005, net income was $6,050 million,
or $4.26 per share, versus $3,691 million, or $2.65 per share, for
2004. Income from continuing operations was $6,054 million, or $4.26
per share, compared with $3,616 million, or $2.60 per share, for the
same period a year ago. Total revenues were $81.5 billion, versus
$62.1 billion a year ago.

    The results for ConocoPhillips' business segments follow.

    Exploration & Production (E&P)

    Second-quarter financial results: E&P income from continuing
operations was $1,929 million, up from $1,787 million in the first
quarter of 2005 and up from $1,354 million in the second quarter of
2004. The increase from the first quarter was primarily the result of
higher realized prices, partially offset by lower volumes and lower
gains on asset sales. In addition, second-quarter results benefited
from lower exploration expenses. Improved results from the second
quarter of 2004 were due primarily to higher realized crude oil and
natural gas prices, partially offset by benefits last year from
Canadian tax law changes, higher production taxes in a higher price
environment and reduced foreign exchange gains.
    As expected, ConocoPhillips' E&P daily production, including
Canadian Syncrude and excluding the LUKOIL Investment segment,
averaged 1.54 million barrels of oil equivalent (BOE) per day, down
from 1.60 million BOE per day for the first quarter and down slightly
from 1.56 million BOE per day in the second quarter of 2004. Compared
with the previous quarter, the company experienced greater output
during the second quarter of 2005 from the Lower 48, Canada and
Venezuela. These increases were more than offset by approximately
45,000 BOE per day of planned downtime, primarily in the Timor Sea,
Alaska and Norway, as well as approximately 25,000 BOE per day of
unscheduled downtime in Norway, Alaska and the United Kingdom. The
decrease from the second quarter of 2004 was due primarily to lower
production in the North Sea and Alaska partially offset by increased
production in Venezuela, the Timor Sea and the Lower 48.
    During the quarter, ConocoPhillips completed the acquisition of a
30 percent interest in the Naryanmarneftegaz joint venture to develop
resources in the Timan-Pechora region of Russia. The amount incurred
to complete the transaction was approximately $512 million.
    Six months financial results: E&P income from continuing
operations for the first six months of 2005 was $3,716 million, up
from $2,611 million in 2004, primarily due to higher realized crude
oil and natural gas prices, partially offset by higher depreciation,
depletion and amortization, higher production taxes and last year's
benefits from tax law changes.

    Midstream

    Second-quarter financial results: Midstream income from continuing
operations was $68 million, down from $385 million in the first
quarter of 2005 and up from $42 million in the second quarter of 2004.
The decrease from the previous quarter was primarily the result of the
first-quarter net benefit to ConocoPhillips associated with a
restructuring of its ownership in Duke Energy Field Services, LLC
(DEFS), including DEFS' sale of its interest in TEPPCO. The increase
over the second quarter of 2004 was due primarily to higher natural
gas liquids prices in both DEFS and the company's consolidated
operations.
    Six months financial results: Midstream income from continuing
operations for the first six months of 2005 increased to $453 million,
from $97 million in 2004. The increase was due primarily to higher
equity earnings from DEFS, which included the first-quarter benefit to
ConocoPhillips associated with the restructuring of its ownership in
DEFS. In addition, natural gas liquids prices in both DEFS and the
company's consolidated operations were higher in the first six months
of 2005, compared with the first six months of 2004.

    Refining and Marketing (R&M)

    Second-quarter financial results: R&M income from continuing
operations was $1,110 million, up from $700 million in the previous
quarter and $818 million in the second quarter of 2004. The increase
in second-quarter 2005 R&M earnings over the previous quarter was
primarily the result of higher U.S. refining market cracks driven by
higher gasoline and distillate demand, as well as increased
throughput. Although light-heavy crude differentials remain strong,
they decreased from high first-quarter levels. Worldwide marketing
margins and sales volumes also improved over the previous quarter. The
improved results from the second quarter of 2004 were due primarily to
increased worldwide refining margins and volumes, and increased U.S.
marketing margins, partially offset by higher turnaround and utility
costs.
    Domestically, second-quarter 2005 realized refining margins
improved 11 percent over the first quarter, while the refineries ran
at 98 percent of crude oil capacity. Successful completion of
first-quarter turnaround activity benefited second-quarter throughputs
while unplanned downtime remained flat quarter-over-quarter.
Turnaround costs were 39 percent lower in the second quarter, compared
with the previous quarter. Marketing margins and volumes also
increased from the previous quarter primarily due to a return to
positive margins on the West Coast during the early part of the second
quarter.
    Internationally, second-quarter 2005 marketing margins and sales
volumes improved over the previous quarter. While northwest Europe
refining market cracks were higher, the turnaround activity at the
Humber refinery during the second quarter did not allow the company to
fully benefit from the favorable market. As a result, international
crude oil capacity utilization was down 6 percent to 94 percent.
    Overall, R&M's refinery crude oil capacity utilization rate
averaged 97 percent, compared with 92 percent in the previous quarter
and 93 percent in the second quarter of 2004. Before-tax turnaround
costs were $106 million, versus $108 million in the first quarter of
2005.
    Six months financial results: R&M income from continuing
operations for the first six months of 2005 increased to $1,810
million, compared with $1,282 million in the first half of 2004. The
increased earnings were driven by higher worldwide refining margins,
partially offset by higher turnaround activity and utility costs.

    LUKOIL Investment

    Second-quarter financial results: Income from continuing
operations in the second quarter of 2005 was $148 million, up from
$110 million in the prior quarter. This represents ConocoPhillips'
estimate of the company's 11.9 percent weighted average equity share
of LUKOIL's income for the second quarter based on market indicators
and historical production trends for LUKOIL. The increase from the
prior quarter was attributable to higher realized price estimates and
an increased equity ownership position. At the end of the second
quarter of 2005, the company's equity ownership in LUKOIL was 12.6
percent.
    ConocoPhillips' share of estimated BOE production was 223,000 per
day and its share of estimated daily refining crude oil throughput was
102,000 barrels per day.

    Chemicals

    Second-quarter financial results: The Chemicals segment, which
includes the company's 50 percent interest in Chevron Phillips
Chemical Company LLC (CPChem), reported income from continuing
operations of $63 million, compared with $133 million in the first
quarter of 2005 and $46 million in the second quarter of 2004. The
decrease from the first quarter was largely due to lower margins from
olefins and polyolefins, as well as lower margins and volumes from
aromatics and styrenics. In addition, second-quarter results were
impacted by higher utility costs due to higher natural gas prices. The
increase from the second quarter of 2004 reflects higher margins from
olefins and polyolefins, partially offset by lower margins and volumes
from aromatics and styrenics, as well as higher utility costs.
    Six months financial results: During the first six months of 2005,
the Chemicals segment had income from continuing operations of $196
million, compared with $85 million for the same period a year ago. The
improvement was due primarily to higher margins in olefins and
polyolefins.

    Emerging Businesses

    The Emerging Businesses segment incurred a loss from continuing
operations of $8 million in the second quarter of 2005, compared with
losses of $8 million in the first quarter of 2005 and $29 million in
the second quarter of 2004. Improved international and domestic power
operations and the timing of certain expenses contributed to the
reduced operating losses compared with the second quarter of 2004.

    Corporate and Other

    Second-quarter after-tax Corporate expenses from continuing
operations were $179 million, compared with $184 million in the
previous quarter and $218 million in the second quarter of 2004. The
improvement from the first quarter was driven primarily by lower net
interest charges and lower benefit-related charges, partially offset
by reduced foreign exchange gains. The decrease in second-quarter net
interest charges was due primarily to lower average debt levels and an
early debt retirement premium paid during the first quarter. The
improvement from the second quarter of 2004 was primarily the result
of reduced net interest expense, partially offset by foreign exchange
losses.
    Total debt at the end of the second quarter was $14.0 billion,
unchanged from the previous quarter and $1.0 billion below year-end
2004. At the end of the second quarter, the company's debt-to-capital
ratio was 22 percent, down from 23 percent at the end of the first
quarter.
    The company's tax provision for the second quarter of 2005 was
$2.3 billion, resulting in an effective tax rate of 42 percent. This
is compared with 41 percent in the previous quarter and 42 percent in
the second quarter of 2004.

    Discontinued Operations

    Second-quarter financial results: Second-quarter 2005 earnings
from discontinued operations were $7 million, compared with an $11
million loss in the first quarter and income of $62 million in the
second quarter of 2004. The improvement from the first quarter is
related primarily to higher margins and the impacts of asset sales.
The decrease from the second quarter of 2004 is related primarily to
the impacts of asset sales.
    Six months financial results: During the first six months of 2005,
discontinued operations had a loss of $4 million, compared with income
of $75 million for the same period a year ago. The decrease is
attributable primarily to the impacts of asset sales.

    Outlook

    Mr. Mulva concluded:

    "Our operating performance, combined with above-average crude oil
and natural gas prices and strong refining margins, contributed to
strong earnings and cash flows.
    "The company continues to grow its asset base through disciplined
capital spending. Compared with our peers, we are redeploying a higher
proportion of our cash flows into projects. These investments are made
possible due to our portfolio of attractive investment opportunities.
Some of these projects are in emerging areas that have high reserve
potential and the possibility to provide long-term value accretion for
our shareholders. One such example is the completion of our E&P joint
venture with LUKOIL in the Timan-Pechora region late in the second
quarter.
    "We expect stronger oil and gas production in the second half of
2005, with full-year production to be approximately 3 percent higher
than that of 2004, excluding the impacts of LUKOIL.
    "As announced earlier this month, we increased our ownership in
DEFS from 30.3 percent to 50 percent. This increase in our strategic
interest emphasizes our commitment, along with Duke Energy, to make
DEFS the industry's top performing U.S. midstream gas company.
    "With respect to downstream, we expect a strong margin environment
and continued high utilization rates in the near term. Our focus is on
continuous improvement and execution of our five-year, $2 billion
clean fuels program. In addition, the five-year, $3 billion
incremental refining investment program that we announced in the first
quarter will result in expanded capacity, stronger processing
flexibility and higher clean product yields throughout our domestic
and international refining network."

    CAUTIONARY STATEMENT FOR THE PURPOSES OF THE "SAFE HARBOR"
PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

    This update contains forward-looking statements within the meaning
of the "safe harbor" provisions of the Private Securities Litigation
Reform Act of 1995. The forward-looking statements, such as "we expect
stronger oil and gas production in the second half of 2005, with full
year production to be approximately 3 percent higher than that of
2004, excluding the impacts of LUKOIL"; "with respect to downstream,
we expect a strong margin environment and continued high utilization
rates in the near term"; "our focus is on continuous improvement and
execution of our five-year, $2 billion clean fuels program"; and "the
five-year, $3 billion incremental refining investment program that we
announced in the first quarter will result in expanded capacity,
stronger processing flexibility and higher clean product yields
throughout our domestic and international refining network" involve
certain risks, uncertainties and assumptions that are difficult to
predict. Further, certain forward-looking statements are based on
assumptions as to future events that may not prove to be accurate.
Therefore, actual outcomes and results may differ materially from what
is expressed or forecast in such forward-looking statements. Economic,
business, competitive and regulatory factors that may affect
ConocoPhillips' business are generally as set forth in ConocoPhillips'
filings with the Securities and Exchange Commission (SEC).
ConocoPhillips is under no obligation (and expressly disclaims any
such obligation) to update or alter its forward-looking statements
whether as a result of new information, future events or otherwise.
    Cautionary Note to U.S. Investors -- The SEC permits oil and gas
companies, in their filings with the SEC, to disclose only proved
reserves that a company has demonstrated by actual production or
conclusive formation tests to be economically and legally producible
under existing economic and operating conditions. Production is
distinguished from oil and gas production because SEC regulations
define Syncrude as mining-related and not part of conventional oil and
natural gas reserves. We use certain terms in this release, such as
"including Canadian Syncrude" that the SEC's guidelines strictly
prohibit us from including in filings with the SEC. U.S. investors are
urged to consider closely the disclosure in the company's periodic
filings with the SEC, available from the company at 600 North Dairy
Ashford Road, Houston, Texas 77079. This information can also be
