Shaw Reports Second Quarter Fiscal Year 2011 Financial Results

BATON ROUGE, La.--(BUSINESS WIRE)--April 11, 2011--The Shaw Group Inc. (NYSE: SHAW) today announced financial results for the second quarter of fiscal year 2011, which ended Feb. 28, 2011.

Second Quarter Fiscal Year 2011 Overview:

• $2.9 billion in new awards for the quarter driven by Environmental & Infrastructure and Power segments, resulting in the overall backlog increasing to $20.6 billion from $19.2 billion in the previous quarter
• Earnings were driven by solid project execution in most segments but were offset by cost increases of $9.5 million after-tax, or $0.11 per share, on an Energy & Chemicals segment project
• Quarterly results also include a previously announced $23 million pre-tax arbitration award payment within our Power segment
• Reduction in earnings per share of $0.06 related to a decrease in percent complete from increased scope of work on a domestic project and currency loss on a foreign project
• Repurchased 1.2 million shares for approximately $47.4 million through the company’s share repurchase program during the quarter and in March, repurchased an additional 4.6 million shares for $154.2 million
• Completed the buyout of a joint-venture partner establishing full control over high-value engineering center in India
• Following the quarter end, the Environmental & Infrastructure segment completed the acquisition of Coastal Planning & Engineering to expand further its water resources and ports and harbor expertise

“Overall, our business segments performed at or better than plan this quarter with the exception of Energy & Chemicals, which was impacted by reduced earnings on a major petrochemical project,” said J.M. Bernhard Jr., chairman, president and chief executive officer of Shaw.

“While the devastating events in Japan have drawn significant attention to the nuclear power industry, work on our nuclear power units currently under construction continues as planned. We believe the Westinghouse AP1000™ technology with its passive safety features will remain a technology of choice for our clients,” continued Mr. Bernhard. “Additionally, Shaw’s experience in performing construction services at nuclear power plants and emergency response services after natural disasters, positions us to assist with the recovery efforts in Japan and any future modification needs to existing power plants in the U.S. and internationally.”

Financial Results:

Because of the non-cash, non-operational impact on reported earnings resulting solely from movement in exchange rates between the U.S. dollar and the Japanese yen, Shaw uses financial results excluding its Investment in Westinghouse segment to measure and communicate financial performance.

The following results exclude Shaw’s Westinghouse segment:

For the second quarter of fiscal year 2011, Shaw’s Westinghouse segment includes a non-cash, non-operating foreign exchange translation loss of $46.9 million pre-tax, or $28.7 million after tax. The prior year’s period included a non-cash foreign exchange translation gain of $39.4 million pre-tax, or $24.2 million after tax.

The following results include Shaw’s Westinghouse segment:

Revision of Prior Period Financial Statements

In preparing the quarterly financial results, we identified an accounting error in our consolidated financial statements affecting fiscal years 2009 and 2010. The error relates to our calculation of revenue on a multi-currency contract in our Energy & Chemicals segment. The effect of this error in fiscal year 2009 was to overstate revenues by $3.4 million and net income and retained earnings by $2.2 million and in fiscal year 2010 to overstate revenues by $16.7 million and net income and retained earnings by $10.7 million. We believe the effects of the error were not material to any previously reported quarterly or annual period, but we are revising our financial reports for fiscal year 2010 herein and in our quarterly report.

Fiscal Year 2011 Guidance:

Guidance for fiscal year 2011 has been updated as follows:

• Revenue: approximately $6.3 billion
• Diluted earnings per share, excluding Westinghouse: $1.86 - $1.91 per share
• Operating cash flow: approximately $0 - $100 million

Presentation Webcast:

Shaw will host an analyst meeting in New York, N.Y., April 11, 2011, at 9 a.m. Eastern. The meeting will feature a presentation by Shaw’s executive management to include financial results for the second quarter of fiscal year 2011, as well as a presentation on Shaw’s nuclear power business. The presentation will be webcast live and archived on Shaw's website at www.shawgrp.com.

Investment in Westinghouse:

Shaw’s subsidiary Nuclear Energy Holdings (NEH) has a 20 percent equity interest in companies collectively known as the Westinghouse Group. NEH financed this investment partially through issuing limited recourse Japanese yen-denominated bonds and, to mitigate the risk associated with foreign currency fluctuation, simultaneously entered into a yen-denominated put option agreement with Toshiba, which provides NEH the option to sell all or part of its equity interest to Toshiba and receive a pre-determined yen-denominated price for the shares.

For U.S. reporting purposes, the yen-denominated bonds are revalued at each quarter’s end to the current U.S. dollar exchange rate; however, the yen-denominated put option, which naturally hedges the foreign exchange movements of the Japanese yen-denominated bonds, is not revalued at current exchange rates for U.S. financial reporting purposes. Therefore, our reported financial results frequently reflect the volatility of the yen-dollar exchange rates showing significant non-cash translation exchange gains or losses.

Calculation of EBITDA:

Shaw defines EBITDA as earnings before interest expense, income taxes, depreciation and amortization. EBITDA is an important financial measure used by Shaw to assess performance. Although it is calculated using components derived from our financial statements prepared under generally accepted accounting principles (GAAP), EBITDA itself is not a GAAP measure.

A table reconciling EBITDA to its most directly comparable GAAP measure is included in the summarized financial information within this release. Calculations of EBITDA should not be viewed as a substitute for calculations under GAAP, including net cash provided by operations, operating income and net income attributable to Shaw. In addition, EBITDA calculations by one company may not be comparable to EBITDA calculations made by another company.

Calculation of Total Cash:

Shaw defines total cash as the sum of cash and cash equivalents, restricted and escrowed cash and cash equivalents, short-term investments and restricted short-term investments.
