Business Segments — Third Quarter 2011

The results of the Company’s two business groups are presented in Table 5 in the accompanying financial tables.

Global Commercial Group

Global Commercial Group revenue for the third quarter of 2011 totaled $369.3 million, compared with $336.5 million in the third quarter of 2010.  The $32.8 million increase in revenue was due primarily to growth from Commercial Services and International activities as discussed below.

Income from operations for the third quarter of 2011 totaled $18.3 million, compared with $32.0 million for the third quarter of 2010.  Operating margins declined to 5.0% for the third quarter of 2011, compared to 9.5% for the third quarter of 2010 due primarily to lower margins in Commercial Services business resulting from non-cash accretion expense of $8.0 million, partially offset by net asset retirement obligation settlement gains.

Commercial Services

Revenue from Commercial Services operations in our Global Commercial Group for the third quarter of 2011 totaled $47.1 million, compared with $42.1 million for the third quarter of 2010.  The increase in revenue was due primarily to the rapid ramp up of activity at our Zion long-term stewardship project, which was partially offset by decreased revenue from engineering projects completed last without corresponding revenue this year.

Gross profit for the third quarter of 2011 totaled $0.9 million, compared with gross profit of $2.6 million in the third quarter of 2010.  Gross margin was 1.9% for the third quarter of 2011, compared with 6.1% for the third quarter of 2010.  The decrease in gross margin was due primarily to $8.0 million of accretion expense primarily related to our Zion Station asset retirement obligation in the third quarter of 2011 compared to $2.1 million in the same quarter of 2010, and to the relative profitability of other major projects preformed. After taking out the effects of non-cash accretion expense, adjusted gross margin was 18.9% for the third quarter of 2011 compared to 10.9% for the same quarter of 2010.

Logistics, Processing and Disposal

Revenue from our Logistics, Processing and Disposal (“LP&D”) operations in our Global Commercial Group for the third quarter of 2011 totaled $64.7 million, compared to $71.0 million in the third quarter of 2010.  The decrease in revenue was due primarily to a large delivery of uranium tubes made in the third quarter of 2010 that was not repeated this year, as well as to lower government transportation service activity during the quarter.

Gross profit for the third quarter of 2011 totaled $24.3 million, compared with $30.6 million for the third quarter of 2010.  Gross margin declined to 37.6% for the third quarter of 2011, compared with 43.1% for the third quarter of 2010.  The decrease in gross margin was attributable primarily to less absorption of fixed costs at our facilities on a lower revenue base, as well as to increased labor costs.

2

International

Revenue from our International operations in our Global Commercial Group for the third quarter of 2011 totaled $257.5 million, compared to $223.4 million for the third quarter of 2010.  Of the $34.1 million increase in revenue, $8.9 million was related to foreign currency fluctuations, while the operational increase in revenue was due to the acceleration of decommissioning activities at two sites under our Magnox contract in the U.K., and to increased design and construction activities in our operations in Asia. Gross profit for the third quarter of 2011 totaled $5.2 million, compared with $8.0 million for the third quarter of 2010.  Gross margin declined to 2.0% for the third quarter of 2011 compared with 3.6% for the third quarter of 2010, due primarily to fewer project based incentive fees available in the third quarter of 2011 compared to the third quarter of 2010.

Government Group

Government Group revenue for the third quarter of 2011 totaled $51.7 million, compared with $81.2 million in the third quarter of 2010.  The decrease in revenue was due primarily to the completion of our Uranium Disposition Services project and the Portsmouth Gas Diffusion Plant remediation project in March 2011, as well as to decreased funding received during the third quarter of 2011 from the American Recovery and Reinvestment Act (“ARRA”) for projects like the Atlas mill tailings clean up project in Moab, UT.  As a result of the completion of the UDS and Portsmouth contracts, the reduction in ARRA funding, and the completion of the Moab contract, the Company anticipates year-over-year decreases for the remainder of 2011.

Income from operations for the Government Group in the third quarter of 2011 totaled $3.4 million, compared with $2.7 million for the third quarter of 2010.  Operating margins increased to 6.5% for the third quarter of 2011 compared to 3.3% for the third quarter of 2010 due primarily to reduced overhead costs associated with the ETTP project bid in 2010 that did not continue into 2011, and to ongoing SG&A cost reduction efforts in 2011.

Equity in income from unconsolidated joint ventures totaled $5.7 million for the third quarter of 2011, compared with $4.0 million for the third quarter of 2010.  The increase was due primarily to a timing difference in recognition of income related to our Hanford tank operating contract.

Outlook

“We are pleased with the progress we have made in the third quarter towards achieving our 2011 strategic and financial objectives.  As expected, our commercial business revenue growth has continued to more than offset declines in our government business,” said Val Christensen, President and Chief Executive Officer.  “With the accelerated progress that we have made so far this year, and based on our current estimated results for the fourth quarter, we are increasing our full year 2011 Adjusted EBITDA guidance to the range of $140 to $150 million.”

The Company defines EBITDA as net income (loss) attributable to EnergySolutions plus interest expense (including the effects of interest rate derivative agreements), income taxes, depreciation, impairment charges and amortization.  The Company defines Adjusted EBITDA as EBITDA plus non-cash equity compensation expense and, non-cash accretion expense, plus or minus nuclear decommissioning trust fund gains or losses net of management fees. The Company uses EBITDA and Adjusted EBITDA as key indicators of its operating performance and for planning and forecasting future business operations. EBITDA and Adjusted EBITDA, as presented in this release, are supplemental measures of the Company’s performance that are not required by, or presented in accordance with, generally accepted accounting principles in the United States (“GAAP”). They are not measures of the Company’s financial performance under GAAP and should not be considered as alternatives to net income or any other performance measures derived in accordance with GAAP or as alternatives to cash flow from operating activities as measures of the Company’s liquidity.

The Company’s measurement of EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures of other companies. The Company has included information concerning EBITDA and Adjusted EBITDA in this release because they are used by management to measure operating performance and because the Company believes that such information is often used by certain investors as measures of a company’s historical performance and for modeling.

EBITDA and Adjusted EBITDA have limitations as analytical tools, and investors should not consider them in isolation, or as a substitute for analysis of the Company’s operating results or cash flows as reported under GAAP. Some of these limitations are:

·                  They do not reflect the Company’s cash expenditures, or future requirements, for capital expenditures or contractual commitments;

·                  They do not reflect changes in, or cash requirements for, the Company’s working capital needs;

·                  They do not reflect the significant interest expense or the cash requirements necessary to service interest or principal payments on the Company’s debt;

·                  Although depreciation is a non-cash charge, the assets being depreciated will often have to be replaced in the future, and EBITDA and Adjusted EBITDA do not reflect any cash requirements for such replacements;

·                  They are not adjusted for all non-cash income or expense items that are reflected in the Company’s statements of cash flows; and

·                  Other companies in the Company’s industry may calculate these measures differently than the Company does, limiting their usefulness as comparative measures.

Because of these limitations, EBITDA and Adjusted EBITDA should not be considered as measures of discretionary cash available to the Company to invest in the growth of its business. The Company compensates for these limitations by relying primarily on its GAAP results and using EBITDA and Adjusted EBITDA only for supplemental purposes.

The Company defines Adjusted Gross Profit as gross profit plus accretion expense.  The Company defines Adjusted Income from Operations as Adjusted Gross Profit less operating expenses.  The Company uses Adjusted Gross Profit and Adjusted Income from Operations as indicators of its operating performance and for planning and forecasting future business operations.  Adjusted Gross Profit and Adjusted Income from Operations, as presented in this release, are supplemental measures of the Company’s performance that are not required by, or presented in accordance with, GAAP. They are not measures of the Company’s financial performance under GAAP and should not be considered as alternatives to gross profit or any other performance measures derived in accordance with GAAP.

The Company defines net income attributable to EnergySolutions before the impact of amortization of intangible assets as net income attributable to EnergySolutions plus amortization expense of intangible assets, net of the related income tax expense. These non-GAAP measures may be useful to investors seeking to compare the Company’s operating performance on a consistent basis from period to period that, when viewed with its GAAP results and the above reconciliation, management believes provides a more complete understanding of factors and trends affecting the Company’s business than GAAP measures alone. These measures should not be considered as substitutes for net income attributable to EnergySolutions, as determined in accordance with GAAP, and you should not consider them in isolation or as a substitute for analyzing the Company’s results as reported under GAAP.
