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, expenses stemming from an employment litigation matter 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.

Note Regarding Forward-Looking Statements

This press release contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements generally relate to future events or the company's future financial or operating performance. In some cases, you can identify forward looking statements because they contain words such as "may," "will," "should," "expects," "plans," "anticipates," "going to," "could," "intends," "target," "projects," "contemplates," "believes," "estimates," "predicts," "potential" or "continue" or the negative of these words or other similar terms or expressions that concern the company expectations, strategy, priorities, plans or intentions.

The company's expectations and beliefs regarding these matters may not materialize, and actual results in future periods are subject to risks and uncertainties that could cause actual results to differ materially from those projected, including the company's ability to forecast its performance; changes in trade policies, in particular the escalation and imposition of new and higher tariffs, which could reduce demand for end products that incorporate our integrated circuits and/or place pressure on our prices as our customers seek to offset the impact of increased tariffs on their own products; 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 revenue 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; and product development delays and defects and market acceptance of the new products. The forward-looking statements contained in this release are also subject to other risks and uncertainties, including those more fully described in the company's filings with the Securities and Exchange Commission ("SEC"), including the company's Annual Report on Form 10-K, filed with the Securities and Exchange Commission on February 7, 2025 and subsequent Quarterly Reports on Form 10-Q filed with the SEC.
