Revenues increased 58 percent year-over-year to $173.7 million; GAAP earnings were $0.65 per diluted share; non-GAAP earnings were $0.76 per diluted share

Share-repurchase authorization increased by $50 million

Power Integrations (Nasdaq: POWI) today announced financial results for the quarter ended March 31, 2021. Per-share measures for all periods reflect the effect of the August 2020 two-for-one stock split.

Net revenues for the first quarter of 2021 were $173.7 million, up 15 percent compared to the prior quarter and up 58 percent from the first quarter of 2020. Net income for the first quarter was $39.8 million or $0.65 per diluted share compared to $0.45 per diluted share in the prior quarter and $0.26 per diluted share in the first quarter of 2020. Cash flow from operations for the first quarter was $58.1 million.

In addition to its GAAP results, the company provided certain non-GAAP measures that exclude stock-based compensation, amortization of acquisition-related intangible assets and the tax effects of these items. Non-GAAP net income for the first quarter of 2021 was $46.7 million or $0.76 per diluted share compared with $0.60 per diluted share in the prior quarter and $0.38 per diluted share in the first quarter of 2020. A reconciliation of GAAP to non-GAAP financial results appears at the end of this press release.

Commented Balu Balakrishnan, president and CEO of Power Integrations: “First-quarter revenues grew 58 percent year-over-year reflecting the strong demand conditions across the industry as well as our continued success in advanced mobile-device chargers, appliances and many other power-supply applications. Distribution sell-through exceeded sell-in again in the first quarter and we have seen continued strength in bookings in recent weeks. As a result, we expect strong year-over-year growth again in the second quarter.”

Power Integrations paid a cash dividend of $0.13 per share on March 31, 2021. A dividend of $0.13 per share will be paid on June 30, 2021 to stockholders of record as of May 28, 2021. Also, the company’s board of directors has added $50 million to its share-repurchase authorization, bringing the total authorization to $91.3 million.

Financial Outlook

The company issued the following forecast for the second quarter of 2021:

• Revenues are expected to be flat compared to the first quarter of 2021, plus or minus five percent.
• GAAP gross margin is expected to be between 49.5 and 50 percent, and non-GAAP gross margin is expected to be between 50 and 50.5 percent. (The difference between the expected GAAP and non-GAAP gross margins is approximately equally attributable to amortization of acquisition-related intangible assets and stock-based compensation.)
• GAAP operating expenses are expected to be approximately $47.5 million; non-GAAP operating expenses are expected to be approximately $38.5 million. (Non-GAAP expenses are expected to exclude approximately $8.8 million of stock-based compensation and $0.2 million of amortization of acquisition-related intangible assets.)

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 ASC 718-10, amortization of acquisition-related intangible assets, and the tax effects of these items. The company uses these measures in its financial and operational decision-making and, with respect to one measure, in setting performance targets for compensation purposes. The company believes that these non-GAAP measures offer important analytical tools to help investors understand its operating results, and to facilitate comparability with the results of companies that provide similar measures. Non-GAAP measures have 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 measures differently, limiting their usefulness as comparative measures. Reconciliations of non-GAAP measures to GAAP measures are attached to this press release.

The above statements regarding the company’s forecast for its second-quarter 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 change. Due to risks and uncertainties associated with the company's business, actual results could differ materially from those projected or implied by these statements. These risks and uncertainties include, but are not limited to: the impact of the COVID-19 pandemic on demand for the company’s products, its ability to supply products and its ability to conduct other aspects of its business such as competing for new design wins; changes in global macroeconomic conditions, including changing tariffs and uncertainty regarding trade negotiations, 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’s revenues to decrease or cause the company to decrease its selling prices for its products; unforeseen costs and expenses; and unfavorable fluctuations in component costs or operating expenses resulting from changes in commodity prices and/or exchange rates. 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 5, 2021.
