Quarterly dividend rises by five percent to $0.20 per share

Power Integrations (NASDAQ: POWI) today announced financial results for the quarter ended September 30, 2023. Net revenues for the third quarter were $125.5 million, up two percent compared to the prior quarter and down 22 percent from the third quarter of 2022. Net income for the third quarter was $19.8 million or $0.34 per diluted share compared to $0.26 per diluted share in the prior quarter and $0.80 per diluted share in the third quarter of 2022. Cash flow from operations for the third quarter was $26.7 million.

In addition to its GAAP results, the company provided non-GAAP measures that for the third quarter of 2023 exclude stock-based compensation, amortization of acquisition-related intangible assets and the related tax effects. Non-GAAP net income for the third quarter of 2023 was $26.6 million or $0.46 per diluted share compared to $0.36 per diluted share in the prior quarter and $0.84 per diluted share in the third quarter of 2022. A reconciliation of GAAP to non-GAAP financial results is included with the tables accompanying this press release.

Commented Balu Balakrishnan, chairman and CEO of Power Integrations: “Our results and forecast reflect the broad-based demand weakness and elevated supply-chain inventories cited by many of our peers this quarter. Notwithstanding the uncertain short-term outlook, our products are winning in the market, design activity remains healthy, and we are making excellent progress on growth initiatives such as EVs, efficient drivers for brushless DC motors, and our proprietary GaN technology.

“We took the next step on our GaN roadmap last month with the introduction of InnoSwitch™ ICs incorporating a 1250-volt PowiGaN™ switch. This breakthrough not only extends the efficiency benefits of GaN to a wider range of applications but also demonstrates that GaN will be a more cost-effective alternative to silicon carbide in the years ahead.”

Power Integrations paid a dividend of $0.19 per share on September 29, 2023, and will pay a dividend of $0.20 per share on December 29, 2023, to stockholders of record as of November 30, 2023. During the third quarter the company repurchased approximately 24,000 shares of its common stock for $1.8 million. The company had $73.4 million remaining on its repurchase authorization as of September 30, 2023.

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, net other operating expenses of $1.1 million in the second quarter of 2022 stemming from a patent-litigation settlement and an offsetting recovery from the liquidation of SemiSouth Laboratories, 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 fourth-quarter financial performance and that GaN will be a more cost-effective alternative to silicon carbide are forward-looking statements reflecting management's current expectations and beliefs. These 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 company’s ability to supply products and its ability to conduct other aspects of its business such as competing for new design wins; changes in global economic and geopolitical conditions, including such factors as inflation, armed conflicts and 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 on February 7, 2023.
