FOR IMMEDIATE RELEASE

May 07, 2007

                       GIANT INDUSTRIES, INC. ANNOUNCES
                     FIRST QUARTER 2007 OPERATING RESULTS

Scottsdale, Arizona, May 07, 2007 - Giant Industries, Inc. [NYSE: GI] today
reported net earnings for the first quarter ended March 31, 2007 of $7.2
million or $0.49 per diluted share. This compares to a net loss for the
first quarter ended March 31, 2006 of $12.4 million or $0.85 per diluted
share.

Fred Holliger, Giant's Chief Executive Officer, said, "Our first quarter 2007
earnings were negatively impacted by reduced operations at our Yorktown and
Ciniza refineries in the months of January and February as we made repairs
necessitated by the fires that occurred at these facilities in the fourth
quarter of 2006. The month of March was, however, exceptional for our
Refining operations as our refineries were operating at high utilization
rates and refining margins were strong throughout our markets.

We are currently in discussions with our insurers regarding our recoveries
relative to the property damage and business interruption loss at Yorktown,
as well as the property damage at Ciniza. In the month of April, we received
a partial advance from our insurers of approximately $1.5 million and we are
hopeful that we will be able to finalize the claim in a timely manner. It
should be noted that a significant portion of the insurance proceeds will be
booked as income at the time they are received. Due to the refining margin
environment at Yorktown during our outage, we believe that these
reimbursements will have an impact on our 2007 earnings."

"In our Retail operations, we continued to realize sales growth as same store
fuel volumes increased by approximately two percent and merchandise sales
increased approximately three percent in the quarter over last year's first
quarter levels. Retail operations' operating profit was; however, lower in
the quarter in comparison to the first quarter last year as a result of lower
fuel margins."

"Our Wholesale operations performed well in the first quarter of 2007 as the
operating income contribution from our Wholesale operations increased by
approximately ten percent, primarily as a result of the additional
contribution from an acquisition completed in January 2007."

Commenting on the 16-inch pipeline that will supply crude oil to the
Company's Four Corners refineries, Holliger commented, "We are nearing
completion of the necessary work to begin shipping crude oil on the
pipeline. We currently anticipate that we should have the pipeline
operational in May with new crude oil at the refineries by the end of June.
As previously noted, when fully operational, the pipeline has sufficient
capacity to allow us to again operate both Four Corners refineries at
maximum rates."

Commenting on second quarter operations, Holliger said, "Refining margins
at the Four Corners refineries and Yorktown refinery are currently higher
than the same time last year. We continue to believe that strong product
demand coupled with favorable market conditions support a positive second
quarter outlook for the industry as well as the remainder of 2007."

"The Wholesale group continues to experience growth in fuel volumes and
fuel margins are stable compared to the same time last year. Our Retail
operations are continuing to experience growth in both merchandise and fuel
sales on a comparable store basis. Recently, fuel margins within our Retail
operations have been lower primarily due to increases in the cost of fuel,
while merchandise margins have remained stable."

Holliger provided the following update on the Company's proposed merger
with Western Refining Company, "On April 12, 2007, the Federal Trade
Commission filed suit against Western and Giant in the Federal District
Court for the District of New Mexico seeking to enjoin the companies'
proposed merger. Giant and Western have previously announced that we
believe the FTC's position is without basis and that we intend to
vigorously challenge the FTC in court. The preliminary injunction hearing
on the claim began on May 7, 2007. Consummation of the transaction remains
subject to this litigation."

Giant's senior management will hold a conference call at 2:00 p.m. EDT on
May 8, 2007 to discuss this earnings release and provide an update on
company operations. The conference call will be broadcast live on the
company's website at www.giant.com.

Our refining margin per barrel is calculated by subtracting cost of products from net sales
and dividing the result by the number of barrels sold for the period. Our fuel margin per
gallon is calculated by subtracting cost of fuel sold from fuel sales and dividing the result
by the number of gallons sold for the period. We use refining margin per barrel and fuel
margin per gallon to evaluate performance, and allocate resources. These measures 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.
