Net sales for Microsemi's fourth quarter, ended September 30, 2007, were $119.7 million, up 16.0 percent from net sales of $103.2 million in the fourth quarter of 2006, and up 5.4 percent from net sales of $113.6 million in the third quarter of 2007. Net sales for the full fiscal year 2007 were $442.3 million, up 19.4% from the $370.5 million for fiscal year 2006.

Non-GAAP gross margin in the fourth quarter was 51.0 percent, compared to 50.3 percent in the fourth quarter of 2006 and 50.9 percent in the third quarter of 2007. Non-GAAP operating margins were 24.2 percent in the fourth quarter compared to 25.8 percent in the fourth quarter of 2006 and 24.9 percent in the third quarter of 2007. For the fourth quarter, non-GAAP net income was $21.8 million, compared to $18.2 million in the fourth quarter of 2006 and $20.5 million in the third quarter of 2007. The non-GAAP effective tax rate was 26.7 percent. Non-GAAP diluted earnings per share in the fourth quarter of 2007 were $0.28 compared to $0.25 in the fourth quarter of 2006, and up $0.02 compared to $0.26 in the third quarter of 2007. Non-GAAP net income for fiscal year 2007 was up $5.2 million or 7.2% at $77.2 million or $1.01 per diluted share, compared to $72.0 million or $1.00 per diluted share for fiscal year 2006.

For the fourth quarter, GAAP gross margin was 39.6 percent compared to 42.3 percent in the fourth quarter of 2006 and 42.0 percent in the third quarter of 2007. GAAP results in the fourth quarter included non-cash acquisition-related charges and other items consisting of $9.8 million for transitional idle capacity, $3.8 million for inventory abandonment adjustments, $2.1 million in amortization of acquisition-related intangibles, $2.9 million related to compensation charges for stock awards, and $1.2 million in other charges. These charges were offset by $0.8 million of credits associated with the finalization of our in-process research and development (IPR&D) valuation, as well as gain from the sale of two company-owned properties of $4.4 million. The GAAP effective tax rate was 33.5 percent. GAAP diluted earnings per share in the fourth quarter of 2007 were $0.13, compared to $0.11 in the fourth quarter of 2006, and $0.11 in the third quarter of 2007. Fourth quarter GAAP net income was $10.1 million compared to net income of $8.1 million in the fourth quarter of 2006 and net income of $8.7 million in the third quarter of 2007.

James J. Peterson, President and Chief Executive Officer, stated, "2007 was a tremendous year for the company. We executed on our business plans growing revenues and profits to record levels. Our PowerDsine acquisition brought us a new product family, significant engineering resources, and a technology roadmap that we will capitalize on for many years. The acquisition became accretive this quarter, ahead of schedule. Our growth in the fourth quarter exceeded overall industry growth expectations with positive contributions from both our high reliability semiconductor and high performance analog mixed signal groups. Visibility into our customer demand is strong and we continue to make operational improvements in order to better service our customers."

The book-to-bill ratio for the quarter was 1.08 to 1.00.

Non-GAAP results are explained and reconciled to GAAP results in the attached tables. Non-GAAP income and non-GAAP operating margins exclude transitional idle capacity and inventory abandonments, manufacturing profit in acquired inventory, amortization of intangible assets, stock option compensation, IPR&D, gain or loss on disposition of assets, restructuring, reserve valuations and other special charges or credits.

Business Outlook

Microsemi expects that for the first quarter of fiscal year 2008 our sales will increase between 2 to 4 percent, sequentially. On a non-GAAP basis, we expect earnings for the first quarter of fiscal year 2008 to be $0.29 to $0.31 per diluted share.

PLEASE READ THE FOLLOWING FACTORS THAT CAN MATERIALLY AFFECT MICROSEMI'S FUTURE RESULTS.

"Safe Harbor" Statement under the Private Securities Litigation Reform Act of 1995: Any statements set forth in the news release that are not entirely historical and factual in nature are forward-looking statements, including without limitation statements concerning the expected benefits of our acquisition of PowerDsine, our expectations regarding visibility into our customer demand, our business outlook, and any other statements of belief or about our plans or expectations. These forward-looking statements are based on our current expectations and are inherently subject to risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. The potential risks and uncertainties include, but are not limited to, such factors as changes in generally accepted accounting principles, the difficulties regarding the making of estimates and projections, the hiring and retention of qualified personnel in a competitive labor market, acquiring, managing and integrating new operations, businesses or assets, uncertainty as to the future profitability of acquired businesses, delays in the realization of any accretion from acquisition transactions, any circumstances that adversely impact the end markets of acquired businesses, difficulties in closing or disposing of operations or assets, difficulties in transferring work from one plant to another, rapidly changing technology and product obsolescence, difficulties predicting the timing and amount of plant closure costs, the potential inability to realize cost savings or productivity gains and to improve capacity utilization, potential cost increases, weakness or competitive pricing environment of the marketplace, uncertain demand for and acceptance of the company's products, adverse circumstances in any of our end markets, results of in-process or planned development or marketing and promotional campaigns, changes in demand for products, difficulties foreseeing future demand, effects of limited visibility of future sales, potential non-realization of expected orders or non-realization of backlog, product returns, product liability, and other potential unexpected business and economic conditions or adverse changes in current or expected industry conditions, business disruptions, epidemics, health advisories, disasters, national emergencies, wars or potential future effects of the tragic events of September 11, 2001, political instability, currency fluctuations, variations in customer order preferences, fluctuations in market prices of the company's common stock and potential unavailability of additional capital on favorable terms, difficulties in implementing company strategies, dealing with environmental or other regulatory matters or litigation, or any matters involving litigation, contingent liabilities or other claims, difficulties and costs imposed by law, including under the Sarbanes-Oxley Act of 2002, difficulties in determining the scope of, and procuring and maintaining, adequate insurance coverage, difficulties and costs of protecting patents and other proprietary rights, work stoppages, labor issues, inventory obsolescence and difficulties regarding customer qualification of products, manufacturing facilities and processes, and other difficulties managing consolidation or growth, including in the maintenance of internal controls, the implementation of information systems, and the training of personnel. In addition to these factors and any other factors mentioned elsewhere in this news release, the reader should refer as well to the factors, uncertainties or risks identified in the company's most recent Form 10-K and all subsequent Form 10-Q reports filed by Microsemi with the SEC. Additional risk factors shall be identified from time to time in Microsemi's future filings. The forward-looking statements included in this release speak only as of the date hereof, and Microsemi does not undertake any obligation to update these forward-looking statements to reflect subsequent events or circumstances.

To supplement the consolidated financial results prepared in accordance with Generally Accepted Accounting Principles ("GAAP"), we use non-GAAP financial measures (non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP income before taxes, non-GAAP net income, and non-GAAP diluted earnings per share) that exclude transitional idle capacity and inventory abandonments, manufacturing profit in acquired inventory, amortization of intangible assets, stock option compensation, IPR&D, gain or loss on disposition of assets and restructuring, reserve valuations and other special charges. Management excludes these items because it believes that the non-GAAP measures enhance an investor's overall understanding of the Company's financial performance and future prospects by being more reflective of the Company's core operational activities and to be more comparable with the results of the Company over various periods. Management uses non-GAAP financial measures internally for strategic decision making, forecasting future results and evaluating current performance. Guidance is provided only on a non-GAAP basis due to the inherent difficulty of forecasting the timing or amount of such items. These items could be materially significant in our GAAP results in any period. By disclosing non-GAAP financial measures, management intends to provide investors with a more meaningful, consistent comparison of the Company's core operating results and trends for the periods presented. Non-GAAP financial measures are not prepared in accordance with GAAP; therefore, the information is not necessarily comparable to other companies' financial information and should be considered as a supplement to, not a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP.

To supplement the consolidated financial results prepared in accordance with Generally Accepted Accounting Principles ("GAAP"), we use non-GAAP financial measures (non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating income, non-GAAP income before taxes, non-GAAP net income, and non-GAAP diluted earnings per share) that exclude transitional idle capacity and inventory abandonments, manufacturing profit in acquired inventory, amortization of intangible assets, stock option compensation, IPR&D, gain or loss on disposition of assets and restructuring, reserve valuations and other special charges. Management excludes these items because it believes that the non-GAAP measures enhance an investor's overall understanding of the Company's financial performance and future prospects by being more reflective of the Company's core operational activities and to be more comparable with the results of the Company over various periods. Management uses non-GAAP financial measures internally for strategic decision making, forecasting future results and evaluating current performance. Guidance is provided only on a non-GAAP basis due to the inherent difficulty of forecasting the timing or amount of such items. These items could be materially significant in our GAAP results in any period. By disclosing non-GAAP financial measures, management intends to provide investors with a more meaningful, consistent comparison of the Company's core operating results and trends for the periods presented. Non-GAAP financial measures are not prepared in accordance with GAAP; therefore, the information is not necessarily comparable to other companies' financial information and should be considered as a supplement to, not a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP.

The items excluded from GAAP financial results in calculating non-GAAP financial results, are set forth below:



 (a)  The restructuring activities involve the closure and
      consolidation of our manufacturing facilities. As these
      facilities are not expected to have a continuing contribution to
      operations or have a diminishing contribution during the
      transition phase, management believes excluding such items from
      the Company's operations provides investors with a means of
      evaluating the Company's on-going operations.  Transitional idle
      capacity relates to unused manufacturing capacity and non-
      productive manufacturing expenses during the period from when
      shutdown activities commence to when all transition activities
      are completed.  Inventory abandonments relate to identification
      and disposal of inventory that will not be utilized after a
      product line is transferred to a new manufacturing location and
      in the fourth quarter of 2007, $3.8 million of this type of
      inventory was deemed unusable and discarded.  Loss on
      disposition of assets results from abandonment of non-productive
      assets in accordance with a restructuring plan.  Restructuring
      and other special charges includes severance and other costs
      related to facilities in the process of closing or already
      closed and one-time events.   The third quarter of 2007 includes
      a $0.3 million loss on liquidation of PowerDsine's marketable
      investments and $0.3 million related to a legal settlement with
      a former distributor.  Management excludes these expenses when
      evaluating core operating activities and for strategic decision
      making, forecasting future results and evaluating current
      performance.

 (b)  While amortization of acquisition related intangible assets is
      expected to continue in the future, for internal analysis of the
      Company's operations, management does not view this expense as
      reflective of the business' current performance.

 (c)  Stock option compensation in connection with the SFAS123R has
      been excluded as management excludes these expenses when
      evaluating core operating activities and for strategic decision
      making, forecasting future results and evaluating current
      performance.

 (d)  In-process research and development has been excluded to
      facilitate the comparability of expenses between periods.  In
      addition, management does not include IPR&D, a one-time
      acquisition-related charge, in measuring core research and
      development costs, nor does it believe that IPR&D is indicative
      of current or future spending.

 (e)  Manufacturing profit in acquired inventory resulted from
      purchase-accounting adjustments to increase the value of
      inventory acquired in the PowerDsine transaction to its fair
      value.  As the acquired inventory is sold, the associated
      manufacturing profit in acquired inventory increases cost of
      goods sold and reduces gross margins.  The manufacturing profit
      in acquired inventory has been excluded to facilitate
      comparability of gross margins between periods.  In addition,
      management excludes the impact of manufacturing profit in
      acquired inventory in internal measurements of gross margin as
      it does not reflect continuing operations at PowerDsine.
      Manufacturing profit in acquired inventory from the PowerDsine
      acquisition will not materially impact gross margins beyond the
      second quarter of fiscal year 2007.

 (f)  Bad debt represents write off of accounts receivable from a
      minor distributor.  This amount is excluded from our GAAP
      results because it is highly unusual and has never occurred
      previously.

 (g)  The primary difference between the GAAP and non-GAAP effective
      tax rates was the effect of exclusion of acquisition-related
      activities.
