               GIANT INDUSTRIES, INC. ANNOUNCES RECORD
                       FIRST QUARTER EARNINGS


Scottsdale, Arizona, May 12, 2004 - Giant Industries, Inc. [NYSE: GI]
today reported net earnings for the first quarter ended March 31, 2004 of
$4.5 million or $0.50 per share. This compares to net earnings for the
first quarter of 2003 of $1.6 million or $0.19 per share.

Fred Holliger, Giant's Chief Executive Officer, said, "We are pleased to
report record first quarter net earnings.  Refining margins at our Four
Corners refineries and Yorktown refinery were quite strong for the
quarter and have improved so far in the second quarter in spite of
continuing high crude oil prices. Our retail operations continued to
perform well as same store fuel volumes and merchandise sales increased
in excess of seven percent over last year first quarter levels. Retail
operations were positively impacted by higher fuel margins while these
improvements were partially offset by lower merchandise margins in the
first quarter of 2004. Phoenix Fuel's operating earnings increased in
excess of thirty percent over the first quarter 2003 level as a result of
higher wholesale fuel margins and sales volumes."

"In the first quarter of 2004, net cash flow from operations was
approximately $52 million. This level was a significant improvement
versus the $33 million of net cash flow from operations in the first
quarter of 2003. Additionally, our cash position at quarter-end was $70.3
million up from $27.3 million at year-end 2003."

"Refining fundamentals in the United States continue to look attractive
for the next several months. As we head into the summer driving season,
gasoline demand remains more than 3 percent above last year and
inventories are low in comparison to historical levels. We believe these
factors should contribute to continued strength in refining margins."

"We believe fuel margins for our retail group are stronger now than they
were this time last year, with same store fuel and merchandise volumes
above the prior year's levels.  Merchandise margins are, however, lower
than they were this time last year.  Phoenix Fuel is off to a very strong
start in the second quarter and is continuing to grow and contribute good
earnings and stable cash flow."

Holliger continued, "We recently completed the sale of approximately 3.3
million shares of common stock and the refinancing of our 9% Senior
Subordinated Notes. The proceeds from the equity offering will be used to
redeem approximately $51 million of our 11% Senior Subordinated Notes. We
have also given notice that we will be prepaying the approximate $20
million outstanding balance under our term loan on July 14, 2004. We plan
to use cash on hand to retire this debt. These debt reduction efforts
will reduce our annual interest payments by approximately $10.6 million
in comparison to the 2003 level, assuming no future borrowings on our
revolving credit facility. After we retire the term loan, we will have
reduced our debt from approximately $450 million to $294 million since
June 30, 2002, the month following the acquisition of the Yorktown
refinery.  We remain committed to further improving our overall financial
health and evaluating growth opportunities to improve shareholder value."

Relative to the recent fire at the Ciniza refinery, Holliger stated, "We
have completed the turnaround at our Ciniza refinery and all units are
currently operating with the exception of the alkylation unit. We
currently expect that the repair of the alkylation unit should be
completed before the end of June."

Giant's senior management will hold a conference call at 1:00 p.m. EDT on
May 13, 2004 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.
