(In millions, except for earnings per share data and percentages)

Revenue for the fourth quarter of 2013 was $353.2 million, a 1% decrease compared to $356.3 million for the third quarter of 2013, and 2% higher compared to $345.1 million for the fourth quarter of 2012. For the full year 2013, revenue of $1.39 billion decreased 3% compared to $1.43 billion for 2012. Excluding the Serial Flash divestiture that occurred in September 2012, full year 2013 revenue was essentially flat as compared to 2012.

GAAP net income totaled $4.5 million or $0.01 per diluted share for the fourth quarter of 2013. This compares to $5.4 million or $0.01 per diluted share for the third quarter of 2013, and a loss of $(12.3) million or $(0.03) per diluted share for the fourth quarter of 2012. GAAP net income for the fourth quarter 2013 was reduced by discrete tax expenses of $23.2 million primarily related to reserves established for non-U.S. tax audits. For the full year of 2013, GAAP net loss was $(24.8) million or $(0.06) per diluted share, compared to GAAP net income of $30.4 million or $0.07 per diluted share for 2012.

GAAP gross margin was 42.7% in the fourth quarter of 2013, which included a $2.2 million loss resulting from facility damage and an unplanned manufacturing shutdown at our Colorado Springs plant. This compares to GAAP gross margin of 40.3% for the third quarter of 2013, which included an $8.9 million loss related to a foundry arrangement, and 38.1% for the fourth quarter of 2012. For the full year 2013, GAAP gross margin was 41.4%, compared to 42.0% for 2012.

Non-GAAP net income for the fourth quarter of 2013 totaled $43.6 million or $0.10 per diluted share, compared to $37.7 million or $0.09 per diluted share in the third quarter of 2013, and $29.4 million or $0.07 per diluted share for the year-ago quarter. For the full year 2013, non-GAAP net income was $120.2 million or $0.27 per diluted share, compared to $145.1 million or $0.32 for 2012. Refer to the non-GAAP reconciliation table included in this release for more details.

Non-GAAP gross margin was 43.7% in the fourth quarter of 2013 compared to 43.1% in the preceding quarter and 41.6% in the fourth quarter of 2012. For the full year 2013, non-GAAP gross margin was 42.5% compared to 43.3% for 2012. Refer to the non-GAAP reconciliation table included in this release for more details.

“Revenue for our microcontroller business increased during 2013, with the core microcontroller business generating robust growth,” said Steve Laub, Atmel's President and Chief Executive Officer. “We are well positioned for 2014 with multiple growth drivers tied to our extensive new product introductions and significant margin expansion from ongoing operational initiatives.”

Cash provided by operations totaled approximately$49.0 millionfor the fourth quarter of 2013, compared to $82.1 millionfor the third quarter of 2013and $78.7 million for the fourth quarter of 2012. Combined cash balances (cash and cash equivalents plus short-term investments) totaled $279.1 million at the end of the fourth quarter of 2013, an increase of $8.2 million from the immediately preceding quarter, even after taking into account the repurchase of $24.2 million in common stock. Cash increases resulted principally from improved operating performance and a reduction in inventory.

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 above.

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

• Loss from manufacturing facility damage and shutdown.

Atmel experienced an unplanned shutdown of its semiconductor manufacturing operations in Colorado Springs, Colorado in the fourth quarter of 2013 due to damage of the facility’s nitrogen plant. All repairs have been completed and the facility has resumed operations. Atmel believes that the loss from the manufacturing facility damage and shutdown is an individually discrete event that is not generally reflective of ongoing operating performance and should be excluded from period-over-period comparisons.

• French building underutilization and other.

The building underutilization and other relates to charges incurred as a result of the insolvency of our tenant in France and prior year real estate taxes relating to an audit assessment of the same facilities in France. Atmel believes that it is appropriate to exclude these charges as they are individually discrete events and generally not reflective of the ongoing operating performance and should be excluded from period-over-period comparisons.

• Loss related to foundry arrangements.

Loss related to foundry arrangements relates to the increase of estimated losses previously recorded with respect to European foundry “take or pay” arrangements for wafers to be delivered during the remaining term of the arrangement. Atmel believes that it is appropriate to exclude the loss related to foundry arrangements from Atmel's non-GAAP financial measures as these losses are generally not reflective of ongoing operating performance and it enhances the ability of investors to compare Atmel's period-over-period operating results from continuing operations.

• (Recovery) impairment of receivables from foundry suppliers.

(Recovery) impairment of receivables from foundry suppliers relates to the Company's assessment of the probability of collecting on receivables from European foundry suppliers for certain services provided by Atmel to those foundries. Atmel believes that it is appropriate to exclude (recovery) impairment of receivables from foundry suppliers 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.  

• Share-based compensation expense.

Share-based compensation expense relates primarily to equity awards such as stock options and restricted stock units. This includes share-based compensation expense related to performance-based restricted stock units for which Atmel recognizes share-based compensation expense to the extent management believes it is 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. Share-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 share-based compensation provide investors with a basis to measure Atmel's core performance against the performance of other companies without the variability created by share-based compensation as a result of the variety of equity awards used by other companies and the varying methodologies and assumptions used.

• Acquisition-related (credits) charges.

Acquisition-related (credits) charges include: (1) amortization of purchased intangibles, which include acquired intangibles such as customer relationships, backlog, core developed technology, trade names and non-compete agreements, (2) contingent compensation expense, which includes compensation resulting from the employment retention of certain key employees established in accordance with the terms of the acquisitions, and (3) adjustments to previously recognized earn-out liability on contingent compensation expense related to acquisitions. In most cases, these acquisition-related charges (credits) 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 (credits) can vary significantly based on the size and timing of acquisitions and the maturities of the businesses being acquired. Excluding acquisition-related charges (credits) 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 (credits) charges.

Restructuring (credits) charges primarily relate to expenses necessary to make infrastructure-related changes to Atmel's operating costs. Restructuring (credits) 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 (credits) 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.

• Credit from reserved grant income.

Atmel recognized a credit from reserved grant income as a result of a ministerial decision executed by the Greek government providing for a partial refund of an outstanding state grant previously made. Based on the execution of this ministerial decision and the subsequent publication of that decision, management determined that it would not be required to repay the full amount of the outstanding grant. Atmel believes that it is appropriate to exclude credit from reserved grant income 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 on sale of assets.

Atmel recognizes gains 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 period-over-period comparisons.

• Settlement charges.

Settlement charges related to legal settlements undertaken in connection with actual or anticipated litigation, or activities undertaken in preparation for, or anticipation of, possible litigation related to intellectual property, customer claims or other matters affecting the business that are generally not reflective of ongoing company performance or ordinary course of litigation expenses.

• Non-GAAP tax adjustments.

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 Atmel's tax returns for the current period/year. 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.
