Power Integrations Reports First-Quarter Financial Results

Quarterly revenues grew five percent sequentially to $76.8 million

SAN JOSE, Calif.--(BUSINESS WIRE)--May 2, 2011--Power Integrations (Nasdaq:POWI), the leader in high-voltage integrated circuits for energy-efficient power conversion, today announced financial results for the quarter ended March 31, 2011. Net revenues for the quarter were $76.8 million, up seven percent compared with the first quarter of 2010, and up five percent compared with the fourth quarter of 2010. Net income was $9.9 million or $0.33 per diluted share, compared with $0.42 per diluted share in the year-ago quarter and $0.30 per diluted share in the fourth quarter of 2010. Gross margin for the first quarter was 47.4 percent; operating margin was 15.2 percent.

In addition to its GAAP results, the company provided certain non-GAAP financial measures that exclude stock-based compensation expenses, amortization of the fair-value write-up of acquired inventory and acquisition-related intangible assets, and the tax effects of these items. Non-GAAP net income for the quarter was $12.1 million or $0.40 per diluted share, compared with $0.49 per diluted share in the year-ago quarter and $0.39 per diluted share in the fourth quarter of 2010. Non-GAAP gross margin for the first quarter was 48.0 percent; non-GAAP operating margin was 18.7 percent.

Commented Balu Balakrishnan, president and CEO of Power Integrations: “Our revenues grew five percent sequentially in the first quarter, with all four major end-market categories contributing to the increase. We also saw an increase in bookings for the second consecutive quarter, and orders remained healthy through the month of April. We believe these trends provide further evidence that the inventory correction that began last summer may now be behind us.”

Balakrishnan continued: “With respect to the tragedy in Japan, we have not experienced any interruption in our ability to supply customers thus far, despite the fact that one of our Japanese foundries has been inoperative since the earthquake due to the ongoing shortage of electricity. We believe that our operational safeguards – including dual-sourcing and a healthy inventory buffer – will enable us to continue meeting customer demand. Also, while we continue to monitor the supply of raw materials into our supply chain, at this time we are not aware of any shortages or other issues that would prevent us from meeting customer demand.

“However, the uncertainty created by the Japan crisis does make forecasting demand more challenging than usual. We have seen some negative impact on demand from our Japanese customers, which account for approximately six percent of our sales; there may also be some effect on overall demand if the manufacturing of power supplies or end products is impacted by shortages of other components or materials. Taking these uncertainties into consideration along with the healthy underlying trends in our business, we expect our second-quarter revenues to be between $76 million and $82 million.”

Note Regarding Use of Non-GAAP Financial Measures

In addition to the company's consolidated financial statements, which are presented according to GAAP, the company provides certain non-GAAP financial information that excludes stock-based compensation expenses recorded under Accounting Standard Codification 718-10, certain acquisition-related expenses such as the amortization of acquisition-related intangible assets and the fair-value write-up value of acquired inventory, and the tax effects of these items. The company uses these non-GAAP measures in its own financial and operational decision-making processes and, with respect to one measure, in setting performance targets for employee-compensation purposes. Further, the company believes that these non-GAAP measures offer an important analytical tool to help investors understand the company’s core operating results and trends, and to facilitate comparability with the operating results of other companies that provide similar non-GAAP measures. These non-GAAP measures have certain limitations as analytical tools and are not meant to be considered in isolation or as a substitute for GAAP financial information. For example, stock-based compensation is an important component of the company’s compensation mix, and will continue to result in significant expenses in the company’s GAAP results for the foreseeable future, but is not reflected in the non-GAAP measures. Also, other companies, including companies in Power Integrations’ industry, may calculate non-GAAP financial measures differently, limiting their usefulness as comparative measures.

Note Regarding Forward-Looking Statements

The statements in this press release relating to the company’s projected second-quarter 2011 financial performance, its belief that the inventory correction is behind it, the expected effects of the tragedy in Japan and its ability to continue meeting customer demand, are forward-looking statements, reflecting management's current forecast. These forward-looking statements are based on current information that is, by its nature, subject to rapid and even abrupt changes. Due to risks and uncertainties associated with the company's business, actual results could differ materially from those projected or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to: changes in global macroeconomic conditions that may impact the level of demand for the company’s products; the ability of the company to obtain sufficient quantities of wafers in a timely manner from its suppliers, especially in light of the uncertainty resulting from the earthquakes and tsunami in Japan; potential changes and shifts in customer demand away from end products that utilize the company's integrated circuits to end products that do not incorporate the company's products; the company's ability to maintain and establish strategic relationships; the effects of competition; customer reaction to the effects of design wins may not be as the company expects; the risks inherent in the development and delivery of complex technologies; the outcome and cost of patent litigation; the company's ability to attract, retain and motivate qualified personnel; the emergence of new markets for the company's products and services; the company's ability to compete in those markets based on timeliness, cost and market demand; unforeseen costs and expenses; fluctuations in currency exchange rates; and the challenges inherent in integrating acquired businesses. In addition, new product introductions and design wins are subject to the risks and uncertainties that typically accompany development and delivery of complex technologies to the marketplace, including product development delays and defects and market acceptance of the new products. These and other risk factors are more fully explained under the caption “Risk Factors” in the company's most recent Annual Report on Form 10-K, filed with the Securities and Exchange Commission (SEC) on February 25, 2011. The company is under no obligation (and expressly disclaims any obligation) to update or alter its forward-looking statements, whether as a result of new information, future events or otherwise, except as otherwise required by the rules and regulations of the SEC.
