For the full year 2011, GAAP gross margin increased to 50.4%, compared to 44.3% for 2010.  Non-GAAP gross margin was 48.7% in the fourth quarter of 2011, which compares to 50.4% in the immediately preceding quarter and 50.0% in the fourth quarter of 2010.  For the full year 2011, non-GAAP gross margin improved to 50.8% compared to 44.8% for 2010.

For the full year 2011, revenue increased 10% to $1.80 billion, compared to $1.64 billion for 2010. Adjusting for the divestiture of the company’s Smart Card business that occurred at the end of the third quarter of 2010, full year 2011 revenue increased 15% from 2010.

“Despite the macroeconomic headwinds that affected the entire industry in the fourth quarter, I’m pleased with the overall results and progress we made across all of our business segments during 2011,” said Steve Laub, Atmel’s President and Chief Executive Officer. “We remain confident that our long-term strategy, exceptional product portfolio, and the recent launch of our new maXTouch “S” series, will enable us to resume accelerated growth rates.”

Fourth quarter 2011 income from operations on a GAAP basis was $49.0 million or 12.8% of revenue, compared with $140.2 million or 29.2% of revenue for the third quarter of 2011 and $93.8 million or 20.5% of revenue for the fourth quarter of 2010. Fourth quarter 2011 income from operations included a $1.1 million restructuring credit and $2.3 million in acquisition related charges, while third quarter 2011 income from operations included a $33.4 million gain from the sale of our corporate headquarters and $1.0 million acquisition related charges, and fourth quarter 2010 income from operations included $1.6 million restructuring charges and $1.2 million of acquisition related charges. The 2011 GAAP full year income from operations was $382.0 million compared to $107.5 million for 2010.

Non-GAAP income from operations in the fourth quarter of 2011 was $68.7 million or 17.9% of revenue, compared to third quarter non-GAAP income from operations of $124.2 million or 25.9% of revenue, and fourth quarter 2010 non-GAAP income from operations of $112.2 million or 24.5% of revenue.  For the full year of 2011, non-GAAP income from operations was $440.3 million compared to $287.5 million for 2010.

Income tax provision, on a GAAP basis, totaled $14.4 million for the fourth quarter of 2011. This compares to an income tax provision of $23.2 million for the third quarter of 2011 and a tax benefit of $133.1 million for the fourth quarter of 2010.  During 2010, the company favorably settled tax audits and released reserves for deferred tax assets which contributed $247.9 million of the total tax benefit recorded for the year.  Non-GAAP income tax benefit

during the fourth quarter of 2011 was $0.5 million compared to $0 for the third quarter 2011. For the full year 2011, non-GAAP tax provision was $1.5 million.

Cash provided from operations totaled approximately $43.4 million for the fourth quarter of 2011, compared to $61.1 million for the third quarter of 2011 and $84.6 million for the fourth quarter of 2010.   Combined cash balances (cash and cash equivalents plus short-term investments) totaled $332.5 million at the end of the fourth quarter of 2011, after spending $135.2 million during the quarter on stock repurchases.

RECONCILIATION OF GAAP FINANCIAL MEASURES TO NON-GAAP FINANCIAL MEASURES

(in thousands, except per-share data)

(Unaudited)

Notes to Non-GAAP Financial Measures

To supplement its consolidated financial results presented in accordance with GAAP, Atmel uses non-GAAP financial measures, including non-GAAP net income and non-GAAP net income per diluted share, which are adjusted from the most directly comparable GAAP financial measures to exclude certain items, as shown above and described below. Management believes that these non-GAAP financial measures reflect an additional and useful way of viewing aspects of Atmel’s operations that, when viewed in conjunction with Atmel’s GAAP results, provide a more comprehensive understanding of the various factors and trends affecting Atmel’s business and operations.

Atmel uses each of these non-GAAP financial measures for internal purposes and believes that these non-GAAP measures provide meaningful supplemental information regarding operational and financial performance. Management uses these non-GAAP measures for strategic and business decision making, internal budgeting, forecasting and resource allocation processes. Atmel may, in the future, determine to present non-GAAP financial measures other than those presented in this release, which it believes may be useful to investors. Any such determinations will be made with the intention of providing the most useful information to investors and will reflect information used by the company’s management in assessing its business, which may change from time to time.

Atmel believes that providing these non-GAAP financial measures, in addition to the GAAP financial results, is useful to investors because the non-GAAP financial measures allow investors to see Atmel’s results “through the eyes” of management as these non-GAAP financial measures reflect Atmel’s internal measurement processes. Management believes that these non-GAAP financial measures enable investors to better assess changes in each key element of Atmel’s operating results across different reporting periods on a consistent basis. Thus, management believes that each of these non-GAAP financial measures provides investors with another method for assessing Atmel’s operating results in a manner that is focused on the performance of its ongoing operations. In addition, these non-GAAP financial measures may facilitate comparisons to Atmel’s historical operating results and to competitors’ operating results.

There are limitations in using non-GAAP financial measures because they are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. In addition, non-GAAP financial measures may be limited in value because they exclude certain items that may have a material impact upon Atmel’s reported financial results. Management compensates for these limitations by providing investors with reconciliations of the non-GAAP financial measures to the most directly comparable GAAP financial measures. The presentation of non-GAAP financial information is not meant to be considered in isolation or as a substitute for or superior to the most directly comparable GAAP financial measures. The non-GAAP financial measures supplement, and should be viewed in conjunction with, GAAP financial measures. Investors should review the reconciliations of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in above.

As presented in the “Reconciliation of GAAP Net Income to Non-GAAP Net Income” tables above, each of the non-GAAP financial measures excludes one or more of the following items:

·                  Stock-based compensation expense.

Stock-based compensation expense relates primarily to equity awards such as stock options and restricted stock units.  This includes stock-based compensation expense related to performance-based restricted stock units for which Atmel recognizes stock-based compensation expense to the extent management believes it probable that Atmel will achieve the performance criteria which occurs before these awards actually vest. If the performance goals are unlikely to be met, no compensation expense is recognized and any previously recognized compensation expense is reversed.  Stock-based compensation is a non-cash expense that varies in amount from period to period and is dependent on market forces that are often beyond Atmel’s control. As a result, management excludes this item from Atmel’s internal operating forecasts and models. Management believes that non-GAAP measures adjusted for stock-based compensation provide investors with a basis to measure Atmel’s core performance against the performance of other companies without the variability created by stock-based compensation as a result of the variety of equity awards used by other companies and the varying methodologies and assumptions used.

·                  Acquisition-related charges.

Acquisition-related charges include: (1) amortization of intangibles, which include acquired intangibles such as customer relationships, backlog, core developed technology, trade names and non-compete agreements and (2) contingent compensation expense, which include compensation resulting from the employment retention of certain key employees established in accordance with the terms of the acquisitions. In most cases, these acquisition-related charges are not factored into management’s evaluation of potential acquisitions or Atmel’s performance after completion of acquisitions, because they are not related to Atmel’s core operating performance. In addition, the frequency and amount of such charges can vary significantly based on the size and timing of acquisitions and the maturities of the businesses being acquired. Excluding acquisition-related charges from non-GAAP measures provides investors with a basis to compare Atmel against the performance of other companies without the variability caused by purchase accounting.

·                  Restructuring charges.

Restructuring charges primarily relate to expenses necessary to make infrastructure-related changes to Atmel’s operating costs.  Restructuring charges are excluded from non-GAAP financial measures because they are not considered core operating activities. Although Atmel has engaged in various restructuring activities in recent years, each has been a discrete event based on a unique set of business objectives. Atmel believes that it is appropriate to exclude restructuring charges from Atmel’s non-GAAP financial measures, as it enhances the ability of investors to compare Atmel’s period-over-period operating results from continuing operations.

·                  Asset impairment charges.

Atmel records an impairment charge, when certain criteria are met, for the difference between the fair value and the carrying value of the assets.   Management believes that is it is appropriate to exclude these non-cash charges from Atmel’s non-GAAP financial measures, as it enhances the ability of investors to compare Atmel’s period-over-period operating results from continuing operations.

·                  (Gain) loss on sale of assets.

Atmel recognizes (gains) loss resulting from the sale of certain non-strategic assets that no longer align with Atmel’s long-term operating plan. Atmel excludes these items from its non-GAAP financial measures primarily because these gains are individually discrete events and generally not reflective of the ongoing operating performance of Atmel’s business and can distort the period-over-period comparison.

·                  Pension charge related to fab sale

Pension charge related to the release of related accumulated other comprehensive loss as a result of Atmel’s sale of its manufacturing operations in Rousset, France and the transfer of employees to the fab buyer. Management believes that it is appropriate to exclude this adjustment from Atmel’s non-GAAP financial measures, as it enhances the ability of investors to compare Atmel’s period-over-period operating results from continuing operations.

·                  Non-GAAP tax adjustment.

In conjunction with the implementation of Atmel’s global structure changes which took effect January 1, 2011, the company changed its methodology for reporting non-GAAP taxes. Beginning in the first quarter of 2011, Atmel’s non-GAAP tax amounts approximate operating cash tax expense, similar to the liability reported on the Atmel’s tax returns, including certain foreign refundable credits.  This approach is designed to enhance the ability of investors to understand the company’s tax expense on its current operations, provide improved modeling accuracy, and substantially reduce fluctuations caused by GAAP adjustments which may not reflect actual cash tax expense.

Atmel forecasts its annual cash tax liability and allocates the tax to each quarter in proportion to earnings for that period.

Non-GAAP tax amounts for periods prior to January 1, 2011 have not been adjusted to reflect this new methodology.
