Revenues increased eight percent sequentially to $71.8 million; cash flow from operations was $21.6 million

SAN JOSE, Calif.--(BUSINESS WIRE)--May 3, 2012--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, 2012. Net revenues for the first quarter were $71.8 million, up eight percent from the prior quarter and down six percent compared with the first quarter of 2011. Net income was $7.5 million or $0.25 per diluted share, compared with $0.22 per diluted share in the prior quarter and $0.33 per diluted share in the first quarter of 2011. Gross margin for the first quarter was 48.2 percent; operating margin was 12.2 percent.

In addition to its GAAP results, the company provided certain non-GAAP financial measures that exclude stock-based compensation expenses, certain acquisition-related costs and expenses, non-cash interest income, and the tax effects of these items. Non-GAAP net income for the quarter was $10.7 million or $0.36 per diluted share, compared with $0.29 per diluted share in the prior quarter and $0.40 per diluted share in the first quarter of 2011. Non-GAAP gross margin for the first quarter was 48.8 percent; non-GAAP operating margin was 17.3 percent.

Commented Balu Balakrishnan, president and CEO of Power Integrations: “Our first-quarter revenues came in ahead of our projections driven by strong sequential growth in industrial and consumer applications. The improvement in bookings that began in November continued through the first quarter and the month of April, and we expect revenues to grow sequentially again in the second quarter. We also expect further improvement in our non-GAAP gross margin, which expanded by a full percentage point in the first quarter.”

Mr. Balakrishnan continued: “Earlier this week we completed our acquisition of CT-Concept, extending our footprint in high-voltage power conversion to include high-power applications such as industrial motor drives, renewable energy systems, mass transit and automotive. With CT-Concept’s innovative IGBT drivers, we can now bring the same benefits of integration – reliability, efficiency and ease of design – to these high-power systems that we already bring to lower-power applications.”

The company issued the following forecast for the second quarter of 2012. The forecast reflects a partial quarter of results from CT-Concept, which Power Integrations acquired on May 1, 2012.

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, acquisition-related transaction expenses, amortization of acquisition-related intangible assets and the fair-value write-up of acquired inventory, non-cash interest income, 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.

The statements in this press release relating to the company’s projected second-quarter 2012 financial performance are forward-looking statements reflecting management's current expectations and beliefs. 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, which may impact the level of demand for the company’s products; 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 effects of competition, which may cause the company to decrease its selling prices for its products; the outcome and cost of patent litigation, which may affect sales of the company’s products or could result in higher expenses and charges than currently expected; unforeseen costs and expenses; unfavorable fluctuations in component costs resulting from changes in commodity prices and/or the exchange rate between the U.S. dollar and the Japanese yen; and the challenges inherent in integrating and forecasting the performance of 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 that may cause actual results to differ 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 29, 2012. 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.
