FREMONT, Calif., April 25, 2011 (GLOBE NEWSWIRE) -- Volterra Semiconductor Corporation (Nasdaq:VLTR), a leading provider of high-performance analog and mixed-signal power management semiconductors, today reported financial results for its first quarter ended March 31, 2011.

Net revenue for the first quarter of 2011 was $34.2 million, a 6% decrease from $36.3 million in the first quarter of 2010, and a 4% decrease from $35.5 million in the fourth quarter of 2010. GAAP net income was $2.7 million, or $0.10 per share (diluted), as compared to $7.7 million, or $0.30 per share (diluted) in the first quarter of 2010, and $3.4 million, or $0.13 per share (diluted), in the fourth quarter of 2010.

Volterra also reported net income and basic and diluted net income per share on a non-GAAP basis. Non-GAAP net income excludes the effect of stock-based compensation expense, net of tax. Non-GAAP net income was $4.6 million, or $0.18 per share (diluted), for the first quarter of 2011, as compared to $8.9 million, or $0.35 per share (diluted), in the first quarter of 2010, and $5.4 million, or $0.21 per share (diluted), in the fourth quarter of 2010.

"We continued gaining share in enterprise notebooks this quarter," said Volterra President and CEO Jeff Staszak. "Our strong product-cycle growth in notebook offset seasonality in servers and a temporary correction in networking. Going forward, we are now poised to resume sequential growth in each of our three strategic market segments."

Non-GAAP Financial Measures

Volterra provides all information required in accordance with generally accepted accounting principles (GAAP), but it believes that evaluating its financial results may be difficult if limited to reviewing only GAAP financial measures. Volterra's management believes the non-GAAP information provided is useful to investors and other users of its financial information and its inclusion with our financial results is warranted for several reasons:

* it can enhance the understanding of Volterra's financial performance by adjusting for special, non-recurring items that may obscure results and trends in our core operating performance, particularly in reconciling differences between reported income and actual cash flows;

* it can provide consistency in reviewing Volterra's historical performance between periods, as well as allowing for better comparisons of Volterra's performance with similar companies in Volterra's industry;

* it allows users to evaluate the results of the business using the same financial measures that management uses to evaluate and manage Volterra's internal planning, budgeting and operations; and

* it provides investors with additional information used by management, its board of directors and committees thereof, to determine management compensation.

Volterra's management reports and uses calculations of (i) non-GAAP gross margin and non-GAAP gross margin as a percent of revenue, which represents gross margin excluding the effect of stock-based compensation; (ii) non-GAAP income from operations (and its components, non-GAAP research and development expense, non-GAAP selling, general, and administrative expense, non-GAAP total operating expenses, and including non-GAAP gross margin as indicated above) as well as non-GAAP operating margin as a percent of revenue which represent income from operations and its components excluding the effect of stock-based compensation and special items such as restructuring charges, net of tax; (iii) non-GAAP annual effective tax rate and the associated non-GAAP income tax expense, which represents the effective tax rate without the effect of stock-based compensation and income tax expense recalculated excluding the effect of stock-based compensation and special items on non-GAAP income before tax; and (iv) non-GAAP net income (and its components listed above), non-GAAP net margin as a percent of revenue, and non-GAAP diluted net income per share, which represents net income and diluted net income per share excluding the effect of stock-based compensation expense and special items such as restructuring charges, net of tax.

Investors should note that the non-GAAP financial measures used by Volterra may not be the same non-GAAP financial measures, and may not be calculated in the same manner, as that of other companies. Whenever Volterra discloses such a non-GAAP financial measure, it provides a reconciliation of non-GAAP financial measures to what it believes to be the most closely applicable GAAP financial measure. A reconciliation of GAAP net income to non-GAAP net income is included in the financial statements portion of this release and at the Investors section of our website at www.volterra.com. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measure. Volterra does not provide a non-GAAP reconciliation for non-GAAP estimates on a forward-looking basis, as it believes it is unable to provide a meaningful or accurate calculation or estimation of stock-based compensation or income tax expenses or other special items without unreasonable effort.
