                 Tesoro Corporation Announces Record
                Third Quarter Earnings and Throughput

    SAN ANTONIO--(BUSINESS WIRE)--Nov. 2, 2006--Tesoro Corporation
(NYSE:TSO) today reported third quarter net income of $274 million, or
$3.92 per share, as compared to $226 million, or $3.20 per share, for
the third quarter of last year. Results for the third quarter include
an after-tax charge of $17 million, or $0.24 per share, related to the
termination of the Anacortes coker project. Excluding this charge,
earnings for the quarter were $4.16 per share. For the first nine
months of 2006, net income was $643 million, or $9.17 per share,
compared to net income of $438 million, or $6.23 per share, for the
nine months ending September 30, 2005.

    The company set a new throughput record this quarter of 574,000
barrels per day which was 15,000 barrels a day greater than the
previous record. The company's refineries in California, Alaska,
Washington and North Dakota each achieved record throughput for an
individual quarter.

    "Over the past 12 months, five of our six refineries have recorded
quarterly record throughput rates. This is just one of many
improvements that have contributed to our strong financial performance
and allowed us to surpass in the third quarter many of our 2005 annual
records," said Bruce A. Smith, Tesoro's Chairman, President and CEO.
Operating income for the first nine months of 2006 was $1.1 billion,
surpassing the company's 2005 full year operating income.

    Operating income for the quarter was up 14% or over $50 million
versus the third quarter of 2005, despite West Coast crack spreads
that were down 15%. This improvement reflects higher reliability and
better optimization of the company's assets through sourcing crude
oils with the best refining value and moving the products into the
right markets. In addition, gross profit margins and capture rates
were higher due to a more stable margin environment. As compared to
the hurricane-driven volatility of last year's third quarter, the
relative stability this year resulted in higher wholesale market
spreads and better realizations of the benchmark crack spread.

    Capital spending for the first nine months of 2006 was
approximately $345 million, of which $59 million was for turnaround
expenditures. For the year, the company anticipates capital spending
of between $550 and $575 million. The company expects capital spending
for 2007 to be between $550 and $650 million including turnarounds.
The Golden Eagle coker modification project is now expected to cost
between $475 and $525 million and the startup has been deferred to
early 2008. Higher raw material costs and limited engineering and
construction resources continue to pressure project costs.

    In addition, the company purchased roughly 815,000 shares of its
common stock for $51 million during the quarter. Year to date through
the third quarter, the company has purchased 2.1 million shares for
$135 million.

    Looking at the immediate quarter, two factors will impact
profitability - normal seasonal demand shifts and the Anacortes
turnaround. While the seasonal demand shift is expected to be typical,
the fundamental outlook remains bullish for product demand in 2007.
Gasoline inventories on the West Coast are low relative to the
five-year average heading into a busy turnaround season that is
expected to extend into the first quarter of next year. In addition,
immediate relief for the industry's need to import high octane
blending components required to produce West Coast gasoline seems
unlikely in the near-term. These factors should provide support for a
strong West Coast margin environment in 2007.

    "Our employees continue to excel in achieving throughput records
through safe and reliable performance. Given each and every employee's
commitment to operational excellence, along with our belief that
historically strong margins will persist, we expect to continue
delivering significant value growth for our shareholders," said Smith.

(d) Management uses gross refining margin per barrel to evaluate
 performance, allocate resources 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 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.
(e) Gross refining margin is revenues less costs of refining
 feedstocks, purchased 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. Also includes the effect of intersegment sales to
 the retail segment at prices which approximate market.
(f) Includes manufacturing depreciation and amortization per
 throughput barrel of approximately $0.97 and $0.64 for the three
 months ended September 30, 2006 and 2005, respectively, and $1.03
 and $0.68 for the nine months ended September 30, 2006 and 2005,
 respectively.
(g) Sources of total product sales include products manufactured
 at the refineries, products drawn from inventory balances and
 products purchased from third parties. Total product sales margin
 includes margins on sales of manufactured and purchased products
 and the effects of inventory changes. Total product sales were
 reduced by 33 Mbpd and 25 Mbpd in the three months and nine
 months ended September 30, 2006 , respectively, as a result of
 recording certain purchases and sales transactions with the same
 counterparty on a net basis beginning in the 2006 first quarter
 upon adoption of EITF Issue No. 04-13, "Accounting for Purchases
 and Sales of Inventory with the Same Counterparty."

 maintenance turnarounds at the Alaska refinery during the 2006 second
 quarter and the California refinery during the 2006 first quarter and
 unscheduled downtime at the North Dakota refinery during the 2006
 second quarter. During the 2005 second quarter, the Company
 experienced reduced throughput at the Hawaii refinery due to a
 scheduled maintenance turnaround. In the 2005 first quarter, the
 Company experienced reduced throughput at the California and
 Washington refineries, primarily as a result of scheduled major
 maintenance turnarounds and unscheduled downtime.

(i) Management uses fuel margin per gallon to compare profitability to
 other companies in the industry. Investors and analysts use fuel
 margin per gallon to help analyze and compare companies in the
 industry on the basis of operating performance. Fuel margin per
 gallon is calculated by dividing fuel gross margin by fuel sales
 volumes. Fuel margin per gallon may not be calculated similarly by
 other companies.
(j) Includes the effect of intersegment purchases from the refining
 segment at prices which approximate market.
