Operating cash flow of $2.7 million

GAAP losses per share of $(0.77) include goodwill and long-lived asset impairment charges of $(0.66) per share

Non-GAAP earnings per share of $0.03

CHELMSFORD, Mass.,Jan. 27 /PRNewswire-FirstCall/ -- Mercury Computer Systems, Inc. (NASDAQ: MRCY) reported results for its second quarter of fiscal 2009, which ended December 31, 2008.

The results of Mercury's Visage Imaging business, which Mercury announced today has been sold to Pro Medicus Limited, are included in continuing operations as of December 31, 2008, but will be reflected as discontinued operations in subsequent periods, including the reclassification of prior period results for comparison.

Second quarter revenues were $50.7 million, an increase of $1.6 million over the first quarter of fiscal 2009, and a decrease of $0.6 million from the prior year's second quarter.

Second quarter GAAP net losses were $(17.1) million, or $(0.77) per share. The second quarter GAAP net losses included $14.6 million, or $(0.66) per share, in goodwill and other long-lived asset impairment charges relating to Mercury's Visage Imaging business.

Second quarter GAAP operating losses were $(16.6) million and include $18.1 million in charges, consisting of $14.6 million in goodwill and long-lived asset impairment charges, $2.6 million in stock-based compensation costs, $0.8 million in amortization of acquired intangible assets, and $0.3 million in restructuring expenses. Excluding the impact of these charges, second quarter non-GAAP operating income was $1.5 million, as compared to $0.1 million in the second quarter of the prior year. Second quarter non-GAAP net income was $0.7 million. Non-GAAP diluted earnings per share were $0.03 for the second quarter.

Cash flows from operating activities were a net inflow of $2.7 million in the second quarter. Cash, cash equivalents, and marketable securities as of December 31, 2008 were $197.9 million, an increase of $30.9 million from September 30, 2008. During the quarter ended December 31, 2008, Mercury received proceeds from borrowings under its line of credit with UBS in the amount of $31.4 million. This line of credit was made available to Mercury, on a "no net cost" basis, during the second quarter as part of a settlement related to Mercury's auction-rate securities investments held by UBS.

"Mercury performed well in the second quarter," said Mark Aslett, President and CEO of Mercury Computer Systems, Inc. "We continued to execute on a plan to focus the business, improve Mercury's profitability, increase our cash flow, and position the Company for renewed growth in fiscal 2010 and beyond. As expected, this was another strong quarter for our ACS defense business, and Mercury Federal made further progress in expanding the Company's total addressable defense market."

"We also made progress toward our goal of divesting our unprofitable and non-core businesses by the end of this fiscal year," Aslett said. "As announced earlier this afternoon, today we signed and closed on the sale of Mercury's Visage Imaging business to Pro Medicus Limited, an Australian company in the healthcare and life sciences space. This removes the business that has been generating Mercury's most significant operating losses and advances us toward completing our portfolio rationalization activities. Looking forward, we are confident that Mercury will conclude the fiscal year as a more focused and profitable enterprise with a strong and growing defense business."

Backlog

The Company's total backlog at the end of the second quarter was $82.6 million, a $5.2 million sequential decrease from the first quarter of the fiscal year, and a $7.0 million decrease from the same quarter last year as reported. Of the current total backlog, $71.8 million represents shipments scheduled over the next 12 months. The book-to-bill ratio was 0.90 for the second quarter and 0.95 for the six months ended December 31, 2008.

Revenues by Operating Unit

Advanced Computing Solutions (ACS) -- Revenues for the quarter from ACS were $44.0 million, representing 87% of the Company's total revenues. Approximately 75% of ACS revenue for the quarter related to defense business as compared to approximately 67% in the same quarter last year.

Visage Imaging (Visage) -- Revenues for the quarter from Visage were $2.5 million, an increase of $0.5 million as compared to the first quarter of the current fiscal year.

Visualization Sciences Group (VSG) -- Revenues for the quarter from VSG were $3.6 million, an increase of $1.3 million as compared to the first quarter of the current fiscal year.

Emerging Businesses -- The results for this segment primarily consist of Mercury's wholly-owned subsidiary Mercury Federal Systems, Inc. (MFS). During the second quarter, MFS secured $1.2 million in bookings and recorded $1.1 million in revenues.

The revenues by operating unit do not include adjustments to eliminate any inter-segment revenues.

Business Outlook

This section presents our current expectations and estimates, given current visibility, on our business outlook for the upcoming fiscal quarter. It is possible that actual performance will differ materially from the estimates given ? either on the upside or on the downside. Investors should consider all of the risks, including those listed in the Safe Harbor Statement below, with respect to these estimates, and make themselves aware of the risk factors that may impact the Company's actual performance.

The following business outlook expectations exclude the results of Mercury's Visage Imaging business unit, which was sold in January 2009 and will be reported as a discontinued operation for all periods beginning in the third quarter of fiscal 2009.

For the third quarter of fiscal year 2009, revenues are currently expected to be in the range of approximately $48 million to $50 million. At this range, GAAP losses from continuing operations per share are currently expected to be in the range of a loss of $(0.02) to earnings of $0.03. Excluding the impact of stock-based compensation costs, amortization of acquired intangible assets, and the difference between expected GAAP and non-GAAP tax rates, third quarter fiscal year 2009 non-GAAP earnings per share from continuing operations are currently expected to range from $0.05 to $0.09.

UNAUDITED SUPPLEMENTAL INFORMATION - RECONCILIATION OF GAAP TO NON-GAAP MEASURES

The Company provides non-GAAP operating income (losses), non-GAAP net income (losses) from continuing operations, and non-GAAP basic and diluted earnings (losses) from continuing operations per share as supplemental measures to GAAP regarding the Company's operational performance. These financial measures exclude the impact of certain items and, therefore, have not been calculated in accordance with GAAP. The adjustments to these non-GAAP financial measures, and the basis for such adjustments, are outlined below:

Stock-based compensation expense. The Company incurs expense related to stock-based compensation included in its GAAP presentation of cost of revenues, selling, general and administrative expense and research and development expense. Although stock-based compensation is an expense of the Company and viewed as a form of compensation, these expenses vary in amount from period to period, and are affected by market forces that are difficult to predict and are not within the control of management, such as the market price and volatility of the Company's shares, risk-free interest rates and the expected term and forfeiture rates of the awards. In accordance with SFAS No. 123R, stock-based compensation expense is calculated as of the grant date of each stock-based award, and generally cannot be changed or influenced by management after the grant date. Management believes that exclusion of these expenses allows comparisons of operating results that are consistent with periods prior to the Company's adoption of SFAS No. 123R, and allows comparisons of the Company's operating results to those of other companies, both public, private or foreign, that either are not required to adopt SFAS No. 123R, or disclose non-GAAP financial measures that exclude stock-based compensation.

Amortization of acquired intangible assets. The Company incurs amortization of intangibles related to various acquisitions it has made in recent years. These intangible assets are valued at the time of acquisition, are then amortized over a period of several years after the acquisition and generally cannot be changed or influenced by management after the acquisition. Management believes that exclusion of these expenses allows comparisons of operating results that are consistent over time for both our newly-acquired and long-held businesses.

Impairment of goodwill and long-lived assets. The Company incurs impairment charges for goodwill and long-lived assets based on events that may or may not be within the control of management. Management believes that these charges are outside the normal operations of the Company's business and are not indicative of ongoing operating results, and that exclusion of these expenses allows comparisons of operating results that are consistent across past, present and future periods.

Restructuring. The Company incurs restructuring charges in connection with management's decisions to undertake certain actions to realign operating expenses through workforce reductions and the closure of certain Company facilities, businesses and product lines. Management believes this item is outside the normal operations of the Company's business and is not indicative of ongoing operating results, and that exclusion of this expense allows comparisons of operating results that are consistent across past, present and future periods.

Tax valuation allowance. The Company records a tax valuation allowance as an expense item when it is "more likely than not" per FAS 109 criteria that the Company will not reap the benefits of the deferred tax assets (future deductible amounts derived from temporary differences between book and taxable income). Management believes these allowances are not indicative of ongoing operating results, and that exclusion of this expense item allows comparisons of operating results that are consistent across past, present and future periods.

Adjustments for related tax impact. Finally, for purposes of calculating non-GAAP net income (losses) from continuing operations and non-GAAP basic and diluted earnings (losses) from continuing operations per share, management adjusts the (benefit) provision for income taxes to tax effect the non-GAAP adjustments described above as they have a significant impact on the Company's income tax (benefit) provision.

Management excludes the above-described items and their related tax impact from its internal forecasts and models when establishing internal operating budgets, supplementing the financial results and forecasts reported to the Company's board of directors, determining the portion of bonus compensation for executive officers and other key employees based on operating performance, evaluating short-term and long-term operating trends in the Company's operations, and allocating resources to various initiatives and operational requirements. The Company believes that these non-GAAP financial adjustments are useful to investors because they allow investors to evaluate the effectiveness of the methodology and information used by management in its financial and operational decision-making.

These non-GAAP financial measures have not been prepared in accordance with GAAP, and should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. These non-GAAP financial measures may not be computed in the same manner as similarly titled measures used by other companies. The Company expects to continue to incur expenses similar to the non-GAAP financial adjustments described above, and investors should not infer from the Company's presentation of these non-GAAP financial measures that these costs are unusual, infrequent or non-recurring.

The following tables reconcile the non-GAAP financial measures to their most directly comparable GAAP financial measures.
