          Tesoro Corporation Announces Third Quarter Results


    SAN ANTONIO--(BUSINESS WIRE)--Nov. 1, 2007--Tesoro Corporation
(NYSE:TSO) today reported net income of $47 million, or $0.34 per
share in the third quarter of 2007, compared to $274 million, or $1.96
per share in the third quarter of 2006. Year-to-date net income
totaled $606 million, or $4.35 per share versus $643 million, or $4.58
per share a year ago.

    Quarterly benchmark crack spreads in the West Coast and Pacific
Northwest regions were down 28% and 34%, respectively from a year ago.
Consequently, refining margins during the quarter of $9.09 per
throughput barrel were $6.16 below those in the third quarter of 2006.

    "The industry experienced a significant increase in crude prices
in the third quarter, while product prices rose at a much slower
rate," said Bruce Smith, Tesoro's Chairman, President and CEO. "These
market fundamentals were the single biggest impact to our quarterly
earnings versus last year. The lower margin environment and rapid rise
in crude price also negatively impacted other segments of our
business, including marketing and our long haul crude hedge program,"
said Smith. The reduction to refinery margins from the realized and
unrealized third quarter hedge program was $28 million.

    Operationally, the company reported throughput of 654 thousand
barrels per day (mbpd) for the quarter. Overall refinery utilization
was good, although the company did experience some unplanned downtime
at our Anacortes and Golden Eagle refineries. Throughput for the
quarter at the Golden Eagle refinery was 11 mbpd lower than a year ago
and is associated with work performed on the coker and other
downstream units. This also increased feedstock cost and reduced clean
product production.

    The Amorco wharf project, completed during the quarter at a cost
of $26 million, offset a portion of the impact of the coker downtime
by providing improved crude flexibility allowing increased utilization
of other conversion units. The project contribution is estimated at
$11 million for the quarter. The sulfur handling unit project at
Anacortes was completed during the quarter and will allow for twice
the refinery's historic sour crude throughput.

    Capital expenditures for the year are expected to remain at $900
million. As of today, the company has completed substantially all of
the major income improvement projects associated with the 2007 capital
program. "As we move into 2008, shareholders should continue to expect
to see our discretionary capital program focused on reliability
improvements and cost savings initiatives. Our successful execution of
the 2007 capital program serves as the foundation for continued
capital stewardship of free cash flow going forward," said Smith.

    Los Angeles Refinery Update

    Throughput at the refinery, including feedstocks, was 110 mbpd.
Gross refining margin and direct operating expense for the quarter
were $8.61 and $5.77 per barrel, respectively.

    "Throughput and product yields are currently ahead of our early
expectations," said Smith. "While market fundamentals in the quarter
of historically low crack spreads and rapidly rising crude cost
impacted the refinery's profitability, we are pleased with our
operational performance. As we move forward, we expect to realize
additional benefits in exiting supply contracts, supply
diversification and enhancing existing logistics," said Smith.

    Retail Operations Update

    Retail operating income during the quarter was $4 million
including an impairment of $6 million for certain retail sites. Volume
and margins for the newly acquired Shell and USA brand sites were in
line with expectations. Additional USA brand expenses to improve
operating standards, store enhancements and security are expected to
impact earnings for the next three quarters. "We have high
expectations for the USA brand, and to meet our company's long-term
strategy around retail, we need to make additional investments. Our
retail strategy is a selective process aimed at matching each
refinery's production with its distribution needs. The addition of the
acquired retail assets has allowed us to achieve a more optimum
channel of trade balance," said Smith.

    Board Declares Quarterly Dividend

    Tesoro announced today that its Board of Directors has approved a
regular quarterly cash dividend of $0.10 per share. The dividend is
payable December 17th, 2007 to shareholders of record as of December
3rd, 2007.

(b)Management uses gross refining margin per barrel to evaluate
    performance and compare profitability to other companies in the
    industry. Gross refining margin per barrel is calculated by
    dividing gross refining margin before inventory changes by total
    refining throughput and may not be calculated similarly by other
    companies. Management uses manufacturing costs per barrel to
    evaluate the efficiency of refinery operations and allocate
    resources. Manufacturing costs per barrel is calculated by
    dividing manufacturing costs by total refining throughput and may
    not be comparable to similarly titled measures used by other
    companies. Investors and analysts use these financial measures to
    help analyze and compare companies in the industry on the basis of
    operating performance. These financial measures should not be
    considered as alternatives to segment operating income, revenues,
    costs of sales and operating expenses or any other measure of
    financial performance presented in accordance with accounting
    principles generally accepted in the United States of America.
(c)Gross refining margin is calculated as revenues less costs of
    feedstocks, purchased refined products, transportation and
    distribution. Gross refining margin approximates total refining
    segment throughput times gross refining margin per barrel,
    adjusted for changes in refined product inventory due to selling a
    volume and mix of product that is different than actual volumes
    manufactured. The adjustment for changes in refined product
    inventory resulted in a decrease in gross refining margin of $5
    million and $19 million for the three months ended September 30,
    2007 and 2006, respectively, and $19 million and $32 million for
    the nine months ended September 30, 2007 and 2006, respectively.
    Gross refining margin also includes the effect of intersegment
    sales to the retail segment at prices which approximate market.
(d)Includes manufacturing depreciation and amortization per throughput
    barrel of approximately $1.35 and $0.97 for the three months ended
    September 30, 2007 and 2006, respectively, and $1.35 and $1.03 for
    the nine months ended September 30, 2007 and 2006, respectively.
(e)Sources of total refined product sales include products
    manufactured at the refineries and products purchased from third
    parties. Total refined product sales margin includes margins on
    sales of manufactured and purchased refined products and the
    effects of inventory changes.

(h)Management uses fuel margin per gallon to compare profitability to
    other companies in the industry. Fuel margin per gallon is
    calculated by dividing fuel gross margin by fuel sales volume and
    may not be calculated similarly by other companies. Investors and
    analysts use fuel margin per gallon to help analyze and compare
    companies in the industry on the basis of operating performance.
    This financial measure should not be considered as an alternative
    to segment operating income and revenues or any other measure of
    financial performance presented in accordance with accounting
    principles generally accepted in the United States of America.
(i)Includes the effect of intersegment purchases from the refining
    segment at prices which approximate market.
