Power Integrations Announces Second-Quarter Financial Results

Net Revenues Were $43.2 Million; Non-GAAP Gross Margin Was 56.0 Percent


SAN JOSE, Calif., Aug. 1, 2007 (PRIME NEWSWIRE) -- Power Integrations (Pink Sheets:POWI) today announced financial results for the three months ended June 30, 2007, and issued its previously unreleased final results for the three months ended March 31, 2007. The company's consolidated statements of operations and consolidated balance sheets for these periods, as well as certain supplemental information, are contained in the tables accompanying this press release.

The company's net revenues for the three months ended June 30, 2007 were $43.2 million, an increase of 4 percent compared to $41.5 million in the year-ago quarter, and a decrease of 5 percent compared to $45.3 million in the first quarter of 2007. Net revenues for the second quarter of 2006 included a net benefit of $2.7 million from the settlement of prior-period ship-and-debit claims with two of the company's distributors. Revenues from product sales, which do not include the impact of this benefit, increased 12 percent compared to the year-ago quarter.

Second-quarter gross margin under generally accepted accounting principles (GAAP) was 55.4 percent. Second-quarter operating expenses on a GAAP basis totaled $17.6 million, including $2.2 million in stock-based compensation expenses. Also included in operating expenses were $0.9 million in expenses related to the company's ongoing efforts to complete its outstanding SEC filings, and $0.6 million in expenses related to patent litigation. Net income under GAAP was $6.8 million, or $0.22 per diluted share.

On a non-GAAP basis, which excludes expenses for stock-based compensation, second-quarter gross margin was 56.0 percent. Non-GAAP operating expenses, which also exclude stock-based compensation expenses, totaled $15.4 million. Non-GAAP net income was $9.2 million, or $0.30 per diluted share.

At June 30, 2007 the company had $149.7 million in cash and investments, an increase of $12.0 million during the quarter.

"As we announced in June, our second-quarter revenues were impacted by the adoption of a competitor's products at a top cellphone OEM," said Balu Balakrishnan, president and CEO of Power Integrations. "However, our business overall remains on track. Revenues came in slightly higher than our revised expectations for the quarter, gross margin was above the high end of the expected range, and cash and investments increased by $12 million during the quarter.

"We had a record quarter in terms of design wins, and the pipeline of ongoing design activity remains very promising," added Balakrishnan. "In particular, adoption of our LinkSwitch products continues to accelerate, driven by energy-efficiency standards as well as the cost-effectiveness of LinkSwitch compared to linear power supplies. LinkSwitch revenues grew more than 30 percent sequentially in the second quarter and comprised 13 percent of revenues, up from 10 percent in the prior quarter."

Revenue mix for the second quarter was 30 percent consumer, 26 percent communications, 20 percent computer, 17 percent industrial and 7 percent other. By product family, preliminary revenue mix for the first quarter was 53 percent TinySwitch(r), 32 percent TOPSwitch(r), 13 percent LinkSwitch and 2 percent DPA-Switch(r).

Power Integrations received 13 U.S. patents and 6 foreign patents during the quarter and had a total of 184 U.S. patents and 89 foreign patents as of June 30.

Status of SEC Filings

Earlier today, the company filed its Forms 10-Q for the first three quarters of 2006. The company currently expects to file its remaining outstanding SEC filings and regain its Nasdaq listing in approximately two weeks.

Third-Quarter Outlook

The company expects its revenues for the third quarter of 2007 to be between $45 million and $47 million, and its GAAP gross margin to be between 53 percent and 55 percent, including an impact of approximately one margin point from stock-based compensation. Operating expenses are expected to total between $18.5 million and $20 million, including $3 million to $4 million in stock-based compensation expenses and approximately $1.3 million related to the company's restatement and efforts to complete its outstanding SEC filings. Of this amount, approximately $1 million relates to charges the company expects to take in connection with addressing the tax implications to non-officer employees arising from certain past stock-option grants.

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 expenses (and the related tax effects thereof) recorded under Statement of Financial Accounting Standards No. 123R, "Share-based Payment," which requires the recognition of expenses relating to share-based payments such as stock options. The company uses these non-GAAP measures in its own financial and operational decision-making processes and 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 company's historical results and 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. 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. Also, other companies, including other companies in Power Integrations' industry, may calculate non-GAAP financial measures differently than the company, limiting their usefulness as a comparative measure.

Note Regarding Forward-Looking Statements

The statements in this press release relating to the company's projected third-quarter financial performance, promising pipeline and expectations regarding the timeline for filing its outstanding SEC filings 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 management's forward-looking statements. These risks and uncertainties include, but are not limited to: changes and shifts in customer demand away from products that utilize the company's integrated circuits to products that do not incorporate the company's products; the company's ability to maintain and establish strategic relationships; the effects of competition; 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; fluctuations in currency exchange rates; and unexpected delays in filing the company's SEC filings. 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 in the company's most recent annual report on Form 10-K, filed with the Securities and Exchange Commission on March 7, 2006. 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.

 Note on use of non-GAAP financial measures:

 Effective January 1, 2006, Power Integrations adopted SFAS 123R, 
 which requires the company to recognize compensation expenses 
 relating to stock-based payments. In addition to the company's 
 consolidated financial statements, which are prepared according to 
 GAAP, the company provides certain non-GAAP financial information 
 that excludes expenses recognized under SFAS 123R, and the related
 tax effects. The company uses these non-GAAP measures in its own 
 financial and operational decision-making processes and 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 company's historical results and 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.
