      GRANITE CONSTRUCTION INCORPORATED REPORTS FIRST QUARTER 2006 RESULTS

    WATSONVILLE, Calif., April 26 /PRNewswire-FirstCall/ -- Granite Construction
Incorporated (NYSE: GVA) today announced a net loss of $1.4 million, or $0.03
per diluted share for the first quarter ended March 31, 2006. This compares with
a net loss of $8.3 million or $0.20 per share for the same period last year.

    William G. Dorey, president and chief executive officer, said, "I am pleased
to report that the momentum that fueled the Branch Division's strong finish in
2005 has carried over into 2006. Despite very wet weather in March in a number
of our West-coast markets, our branch business is off to a great start. The
branches continue to capitalize on healthy public and private sector markets and
a strong demand for our construction materials throughout the West. With regard
to our Heavy Construction Division (HCD), we are disappointed that they did not
contribute to our first quarter bottom line results as we had expected. We
remain focused on the potential of our large project business and continue to
work diligently to improve the gross margins on this work."

    Total Company Operating Results - Quarter

    The operating loss for the quarter was $3.8 million compared with $11.9
million for the first quarter ended March 31, 2005. Included in the first
quarter 2006 results is a gain of approximately $2.3 million from the sale of an
investment property as well as a higher level of equipment sales than in the
prior period. Revenue for the first quarter 2006 totaled $496.0 million compared
with $420.9 million a year ago. Total gross profit as a percent of revenue
increased 1.7% to 8.1%. Backlog at March 31, 2006 totaled $2.5 billion compared
with $2.6 billion at March 31, 2005.

    Operating Results by Division - Quarter

    Branch Division operating income for the quarter increased to $18.8 million
compared with an operating loss of $1.1 million a year ago. Revenue for the
division totaled $251.1 million, an increase of $32.4 million or 15% over the
same period in 2005. Backlog increased 51% to $877.5 million compared with
$582.8 million at March 31, 2005. Branch Division gross profit as a percent of
revenue was 17.4% compared with 9.0% for the first quarter 2005. The increase in
gross margin reflects approximately $7.0 million from the settlement of
outstanding issues on two projects as well as higher profit margins for both
construction and construction materials.

    HCD operating loss for the quarter was $12.1 million compared with a loss of
$1.3 million in the first quarter 2005. The loss primarily reflects the
recognition of significant increases in the estimated costs to complete six
large projects. HCD revenue for the quarter totaled $244.8 million versus $202.0
million for the same period last year. Backlog was $1.7 billion at March 31,
2006 compared with $2.0 billion at March 31, 2005. HCD incurred a loss at the
gross margin level of 1.2% of revenue compared with a profit of 3.5% of revenue
for the first quarter 2005.



    Outlook

    Commenting on the Company's outlook, "Given the current prospects for our
Branch Division, and assuming no significant downturn in market conditions, we
expect the 2006 operating income for the division to meet or exceed the record
level reached in 2005. Despite a disappointing start, we continue to expect
incremental improvement from HCD in 2006," said Dorey.
