Tesoro Petroleum Corporation Reports Fourth Quarter and Full Year
Results

    SAN ANTONIO--(BUSINESS WIRE)--Feb. 3, 2004--Tesoro Petroleum
Corporation (NYSE:TSO) today reported a net loss of $7.9 million, or
$0.12 per share, for the fourth quarter of 2003 compared to a net loss
of $27.7 million, or $0.43 per share, for the fourth quarter of 2002.
Excluding special items, the net loss was $1.5 million, or $0.02 per
share, compared to a net loss excluding special items for the fourth
quarter of 2002 of $15.5 million, or $0.24 per share.
    As reported in the attached financial information, results for the
quarter included after-tax charges of $6.4 million, or $0.10 per
share, which were primarily non-cash charges for the termination of
its funded supplemental executive retirement plan (SERP) and an
impairment write-down on certain retail gas stations. Fourth quarter
2002 results included after-tax charges of $12.2 million, or $0.19 per
share, which were charges for a change in income tax rates, an
impairment write-down for the sale of certain retail assets, financing
costs related to the acquisition of Golden Eagle, along with severance
and integration costs.
    For the full year of 2003, the company reported net earnings of
$76.1 million, or $1.17 per diluted share, versus a net loss for the
full year of 2002 of $117.0 million, or $1.93 per share. Excluding
special items, full year 2003 net earnings were $115.8 million, or
$1.78 per diluted share, compared to a net loss of $95.5 million, or
$1.58 per share, for the full year of 2002.
    As reported in the attached financial information, results for the
full year 2003 included after-tax charges of $39.7 million, or $0.61
per diluted share, for the write-off of unamortized debt issuance
costs, termination of the SERP, charges for early retirement,
severance and integration costs and impairment losses on the sale of
Marine Services and certain retail stations. Full year 2002 results
included net after-tax charges of $21.5 million, or $0.35 per share,
for financing costs related to the acquisition of Golden Eagle,
changes in the income tax rate, an impairment write-down for the sale
of certain retail assets, severance and integration costs and a LIFO
inventory benefit.
    "Low seasonal demand for refined products combined with rapidly
rising crude oil prices narrowed margins in all of our refining
regions compared to the third quarter of 2003," said Bruce A. Smith,
Chairman, President and CEO of Tesoro. "The rise in crude oil prices
also negatively impacted margins on certain products, mainly jet fuel,
due to contract pricing lags. In addition, we elected to conduct major
maintenance work at our Golden Eagle and Anacortes refineries, which
further impacted fourth quarter profitability."
    "In 2003, Tesoro had many notable successes. We strengthened our
balance sheet by achieving our $500 million debt reduction goal and we
ended the year with $77 million of cash. We negotiated a more
flexible, less expensive credit agreement and rationalized our asset
base by trimming non-core and under-performing assets. In addition,
despite higher utility expenses, we made good progress in right-sizing
our cost structure, and we exercised good capital discipline as we
rationalized our capital expenditures," stated Smith.
    "This year, our goal will be to improve the profitability of our
operations by achieving greater operating efficiencies, and from the
benefit of lower interest expense resulting from our debt reduction.
We will also continue to be good capital stewards, without
compromising operating safety or reliability. These factors plus our
expectation of an improved industry margin environment, should enable
us to continue to meet our principal goal of reducing debt," added
Smith.

Note: Results include the California refinery operations acquired in
May 2002 and interest expense for the related financing.

(a)  In December 2003, the Company terminated the funded
     supplemental executive retirement plan resulting in a
     non-cash settlement charge of $6.9 million and a charge of
     $1.5 million relating to a plan curtailment contribution.

(b)  In October 2003 the Company entered into an agreement to
     sell substantially all of the physical assets of Marine
     Services for approximately $32 million including inventories.
     The Company recorded a pretax loss of $7.6 million during the
     2003 third quarter, reflecting the expected loss on this sale.
     The sale of the Marine Services assets was completed in
     December 2003.  In the 2003 fourth quarter, the Company
     wrote-off certain refinery assets that were replaced and
     recorded an impairment loss on certain retail stations.
     The pretax loss on asset sales in 2002 related primarily
     to the loss of $4.0 million on a sales/lease-back transaction
     for 30 retail stations and a $2.5 million loss in the 2002
     fourth quarter on the sale of 70 retail stations in northern
     California.

(c)  During 2003 the Company wrote-off approximately $36.2
     million, pretax, of unamortized debt issue costs related
     to voluntary prepayments of debt and the replacement of
     the Company's previous credit facility with a new credit
     agreement and term debt during the 2003 second quarter.
     During the first six months of 2002 the Company also
     recorded pretax charges of $12.6 million for financing
     costs related to the acquisition of the California refinery.

(e)  Management uses gross refining margin per barrel to compare
     profitability to other companies in the industry.  Gross refining
     margin per barrel is calculated by dividing gross refining margin
     by total refining throughput and may not be calculated similarly
     by other companies.

(f)  Management uses manufacturing costs per barrel to evaluate the
     efficiency of refinery operations.  Manufacturing costs per
     barrel may not be comparable to similarly titled measures used
     by other companies.

(g)  Gross refining margin is revenues less cost of refining
     feedstock, which 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. In addition, during the 2002 third quarter, certain
     inventory quantities were reduced, resulting in the
     liquidation of applicable LIFO inventory quantities carried at
     lower costs. This reduction in LIFO inventory resulted in a
     decrease in cost of sales of approximately $5 million and a
     decrease in net loss of $3 million for the year ended December
     31, 2002.

(h)  Includes manufacturing depreciation and amortization per
     throughput barrel of approximately $0.62 and $0.61 for the three
     months ended December 31, 2003 and 2002, respectively, and $0.59
     and $0.56 for the years ended December 31, 2003 and 2002,
     respectively.

(i)  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 included margins on sales of manufactured and purchased
     products and the effects of inventory changes.

(j)  Volumes for the year ended December 31, 2002 include amounts
     for the California operations since acquisition on May 17,
     2002 averaged over the full year. Throughput and yield
     averaged over the 229 days of operation were 150,800 bpd and
     160,000 bpd, respectively. The California refinery's
     throughput and yield levels were reduced during a scheduled
     maintenance turnaround in the 2002 second quarter.
