FOR IMMEDIATE RELEASE
Mercury Computer Systems Implements Plan
to Restore Profitability and Growth
CHELMSFORD, Mass. – May 1, 2007 – Mercury Computer Systems, Inc. (NASDAQ: MRCY) announced that it is implementing a comprehensive restructuring plan designed to return the Company to profitability and restore growth. As announced in the April 26 3QFY07 earnings release, the Company will make strategic cost reductions for its new fiscal year.
Management is restructuring the organization around common capabilities to achieve better strategic focus. The Company will renew growth by focusing resources and management attention on three key areas:
| • | | Increase market share in current advanced computing segments |
| • | | Expand growth in 3D visualization and PACS (picture archiving and communications systems) in Life Sciences |
| • | | Focus on new business in the national intelligence computing markets and emerging homeland security market. |
The Company will consolidate its specialized computing businesses into a single new operating unit called Advanced Computing Solutions. This structure will allow the Company to more readily leverage its R&D investments and capabilities across numerous markets including semiconductor, communications, seismic, and multiple defense applications. Furthermore, Mercury’s Life Sciences business, now organized as part of Commercial Imaging and Visualization, will operate as an independent business unit focusing on the 3D PACS market.

Mercury will achieve additional cost synergies, eliminate management layers, and reduce other operating expenses including discretionary spending, which are expected to result in annual cost savings of approximately $15 million per year. The Company’s U.S. workforce will be reduced by approximately 80 positions within the defense and commercial business units and corporate functions. A restructuring charge of approximately $4 million will be taken in 4QFY07, to be paid primarily over the next three quarters. The 4QFY07 guidance as outlined in the Company’s April 26 announcement is not expected to change, as the benefit of these cost reductions is expected to be minimal in the current quarter.
