Business Outlook

This section presents our current expectations and estimates, given current visibility, on our business outlook for the upcoming fiscal quarter and the fiscal year. 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.

For the fourth quarter of fiscal year 2008, revenues are currently expected to be in the range of approximately $53 to $56 million. The Company currently expects fourth quarter fiscal 2008 GAAP losses per share to be in the range of a loss of $0.30 to a loss of $0.22. Excluding the impact of stock-based compensation costs, amortization of acquired intangible assets, and restructuring and impairment costs, fourth quarter fiscal year 2008 non- GAAP per share estimates are currently expected to be in the range of a loss of $0.05 to earnings of $0.01.

For the full year, the Company currently expects revenues to be in the range of approximately $211 to $214 million, increasing the bottom end of the range from the previously guided $209 million to $214 million. The Company currently expects fiscal year 2008 GAAP losses per share to be in the range of a loss of $0.99 to a loss of $0.91. Excluding the impact of stock-based compensation costs, amortization of acquired intangible assets, the inventory writedown, and restructuring and impairment costs, fiscal year 2008 non-GAAP earnings per share are currently expected to be in the range of $0.12 to $0.18.

"In the near term, we expect to continue improving the underlying operations of the business and generating cash flow from operations," Mr. Aslett said. "We will also continue to seek opportunities to focus the business and rationalize our portfolio. At the same time, we expect to develop and launch new products in ACS that will support future growth. These initiatives are longer-term efforts, where progress will be made incrementally, quarter by quarter, by consistently improving execution."

Third Quarter Highlights

February -- Mercury announced three new additions to its management team: Alex Van Adzin as Vice President and General Counsel, Leon Woo as Vice President of Engineering for ACS, and Stephen Anderson as Vice President of Product Operations for ACS. Mr. Van Adzin leads the overall direction and management of Mercury's legal affairs and is responsible for a broad range of corporate, legal, and regulatory functions essential to supporting Mercury's success. Messrs. Woo and Anderson, who previously worked together for 17+ years, are tasked with bringing an aligned understanding of engineering, supply chain and product management that will firmly support the Company's product strategy going forward.

February -- Mercury announced its VS6-210 P.A. Semi Dual Dual-Core VXS Module. As the best in class for size, weight and power, the VS6-210 employs industry-standard technologies and an open software environment specifically architected for high-performance multicomputing sensor applications including radar, sonar, communications, and imaging. The P.A. Semi device delivers high performance with low power consumption; depending upon the application, three to four times less power consumption than similar high-performance microprocessor platforms.

February -- Mercury announced its Dual Cell-Based System 2 (DCBS-2) and new-generation MultiCore Plus(TM) SDK (Software Development Kit). The new multicore hardware and software offerings provide dramatic performance and productivity gains for wafer and mask inspection, beam writers, EDA (electronic design automation), computational lithography, aerospace and defense applications, and more. The DCBS-2 employs two Cell Broadband Engine(TM) (BE) processors to boost applications that demand a low acoustic signature in combination with the added density of the 1U form factor. The MultiCore Plus SDK is a cost-effective, seamless package of software development tools and libraries within a comprehensive programming framework that is specially designed for next-generation multicore processors such as the Cell BE processor.

March -- Mercury received a $2.5 million contract award from U.S. Army Ft. Monmouth's CECOM in New Jersey for development and demonstration of a testbed to support the Joint Counter Radio-Controlled Improvised Explosive Device Electronic Warfare (JCREW) program. The testbed will be used by the U.S. Government to develop and test advanced open-architecture technology for counter-IED (improvised explosive device) systems development. Mercury also announced a related agreement with ITT Electronic Systems, a leading supplier of information and electronic warfare (EW) technologies, systems, and services that enable mission success and survivability for a broad range of military aircraft. Through collaboration with ITT's Electronic Warfare Systems business, the strengths of each organization shall be leveraged to demonstrate algorithm component portability for the JCREW testbed architecture, which is an important element of the R&D objectives of the program.

March -- Mercury Federal Systems, Inc., a wholly owned Mercury subsidiary that offers consulting and software engineering services to the government, showcased its edge computational capabilities for C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance) systems, at the Navy League Sea-Air-Space Exposition in Washington, DC . Mercury Federal Systems was also named an Industrial Partner of COEUT, the Center of Excellence in Undersea Technology. COEUT's mission is to perform basic and applied research focused on the design, development, testing, and implementation of a wide variety of undersea technologies that support both military and civilian applications such as ocean and sea floor monitoring; underwater communication, detection and classification systems; and virtual ocean simulators.

April -- Mercury announced two design wins in radar and image processing applications in sensor computing. For next-generation radar on the go, Mercury is working with a leading defense prime contractor to integrate a ruggedized, conduction-cooled RACE++(R) Mercury multicomputer to operate as the radar processor for an airborne platform with significant environmental constraints. For precision approach and landing capability in military aircraft, Mercury is providing high-speed computation with the Momentum(TM) Series VPA-200 single-board computer. The VPA-200 will be integrated into a GPS to enable aircraft to land on any sufficient land- or sea-based surface during adverse weather or terrain conditions such as a low ceiling, cross winds, extreme precipitation, poor visibility, and widespread surface debris.

April -- Mercury was awarded design wins by two global technology companies that specialize in information systems and solutions for security applications. Mercury supplied the Momentum Series VLA-150 UltraSPARC(R) IIi+ Single-Board Computer, as well as obtained inventory of UltraSPARC IIi+ processors, for a long-standing defense customer. As a result, Mercury has helped the customer to sustain a leading reconnaissance program that deploys UAVs, and avoid a premature technology refresh. Also, a leading provider of inspection solutions turned to Mercury to gain a competitive edge for its scanning system. Mercury provided a Cell BE processor-based solution that combined a customized algorithm, the MultiCore Framework software, and professional services. As a result, the customer achieved a 5x performance increase and enhanced image scans.

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

The Company provides non-GAAP operating income (losses), non-GAAP net income (losses), and non-GAAP basic and diluted earnings (losses) 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.

In-process research and development. The Company incurs in-process research and development expenses when technological feasibility for acquired technology has not been established at the acquisition date and no future alternative use for such technology exists. These costs do not relate to the Company's ongoing operations and generally cannot be changed or influenced by management at the time of or 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 acquired intangible assets in business combinations. The Company incurs impairment charges of acquired intangible assets in business combinations, such as a non-compete agreement, based on events that may or may not be within the control of management. 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.

Inventory writedown. The Company incurred a significant inventory writedown in the third quarter of fiscal 2008, resulting from the closure of one of our businesses. Management believes this item was outside the normal operations of the Company's business and is not indicative of ongoing operating results, and that exclusion of this writedown 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.

Adjustments for related tax impact. Finally, for purposes of calculating non-GAAP net income (losses) and non-GAAP basic and diluted earnings (losses) 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 expenses 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.

Assuming a 30% tax rate, dilution occurs when net income is $3.0 million per quarter. Accordingly, for non-GAAP net income (loss) per share for the three months and nine months ended March 31, 2008 and March 31, 2007, diluted shares exclude the conversion of the convertible debt as the effect would be anti-dilutive.
