            The Shaw Group Announces Financial Results for
                    Fourth Quarter and Fiscal 2006

    BATON ROUGE, La.--(BUSINESS WIRE)--Oct. 31, 2006--The Shaw Group
Inc. (NYSE:SGR):

    --  Record backlog of $9.1 billion reflects continued strong end
        markets.

    --  Fourth Quarter and Fiscal Year 2006 Revenues increased 44% and
        46%, from prior year revenues, respectively.

    --  Operating cash flow totals $163.7 million for fourth quarter.

    The Shaw Group Inc. (NYSE:SGR) today announced financial results
for its fiscal fourth quarter and fiscal year ended August 31, 2006.
Net income for the fourth quarter was $13.0 million, or $0.16 per
diluted share, which included a charge of approximately $19.6 million,
$11.9 million after taxes, or approximately $0.15 per diluted share,
for previously disclosed cost overruns on a domestic clean fuels
project and a $1.0 million loss from discontinued operations, after
taxes, or $0.01 per diluted share. Excluding the charge on the clean
fuels project, net income would have been $24.9 million, or $0.31 per
diluted share. In comparison, for the three months ended August 31,
2005, Shaw reported net income of $17.2 million, or $0.22 per diluted
share. Revenues for fourth-quarter 2006 were $1,174.5 million compared
to $816.8 million in the prior year quarter, a 44% increase. During
fourth-quarter 2006, Shaw generated operating cash flow of $163.7
million, compared to $4.2 million in fourth-quarter 2005.

    For the fiscal year ended August 31, 2006, the Company reported
net income of $50.9 million, or $0.63 per diluted share, which
included a non-cash charge totaling $48.2 million, $29.2 million after
taxes, or $0.36 per diluted share, for the previously reported
unfavorable ruling on the AES Wolf Hollow litigation. Not including
the charge, net income would have been $80.0 million, or $1.00 per
diluted share, for fiscal 2006. For the fiscal year ended August 31,
2005, the Company reported net income of $16.0 million, or $0.23 per
diluted share, including charges of $47.8 million, $31.1 million after
taxes or $0.44 per diluted share for the early retirement of debt and
$6.9 million after taxes, or $0.10 per diluted share for the valuation
of a deferred tax asset. Excluding the charges in prior year, net
income would have been $53.9 million or $0.77 per diluted share.
Revenues for the fiscal year ended August 31, 2006, were $4.8 billion,
compared to $3.3 billion for the fiscal year ended August 31, 2005, an
increase of 46%.

    Shaw's backlog totaled $9.1 billion as of August 31, 2006, a new
record and an increase of $2.4 billion from the August 31, 2005,
backlog of $6.7 billion. Approximately $4.1 billion, or 45%, of the
backlog is expected to be converted during the next 12 months. Nearly
$4.4 billion, or 49%, of the backlog is comprised of projects for
fossil fuel, nuclear and other power generating plants, and
approximately $1.9 billion, or 20%, of the backlog is made up of the
chemical industry projects. Approximately $2.8 billion, or 30%, of the
backlog is in the environmental and infrastructure sector, primarily
contracts with federal and other governmental agencies.

    J.M. Bernhard, Jr., Chairman and Chief Executive Officer of The
Shaw Group Inc., said, "As we previously disclosed, our fourth-quarter
2006 financial results were negatively affected by charges on a
domestic clean fuels project related to cost overruns for which
payment is disputed by our customer. Notwithstanding those charges,
our operating results were strong in every sector of our business. We
continue to see this strength building over time, especially in our
electricity generation business."

    Mr. Bernhard continued, "As we look to the future, we believe
nuclear power will be a key component for meeting the energy needs of
our nation and the world. Our recent investment to become a 20% owner
of Westinghouse Electric demonstrates our confidence in nuclear power
and complements our nuclear services capabilities. We believe nuclear
power will create significant opportunities for us - providing
architect-engineer, design, procurement, construction and expansions
and uprates for existing nuclear power plants, as well as new-build
opportunities."

    Mr. Bernhard concluded, "Lastly, our $9.1 billion backlog, another
record, is 35% higher than last year and 57% higher than two years
ago, reflecting the exceptional strength we have seen in the power and
chemical process markets. What's encouraging is that we still see
strong growth possibilities ahead in these markets even after such
exceptional performance over the past two years. We expect our
revenues and financial performance will soon begin to reflect
execution on several of these major projects."

    The Shaw Group Inc. is a leading global provider of engineering,
procurement, construction, technology, maintenance, fabrication,
