Power Integrations Reports Third-Quarter Financial Results
Revenue increased five percent sequentially to $125.5 million; GAAP earnings were $0.32 per diluted share; non-GAAP earnings were $0.46 per diluted share
Cash flow from operations was $42.6 million; quarterly dividend to increase to $0.22 per share in 2027
SAN JOSE, Calif. – November 4, 2026 – Power Integrations (NASDAQ: POWI) today announced financial results for the quarter ended September 30, 2026. Revenue for the third quarter was $125.5 million, up five percent from the prior quarter and up six percent from the third quarter of 2025. GAAP net income for the third quarter was $18.3 million or $0.32 per diluted share compared to $0.17 per diluted share in the prior quarter and a net loss of $0.02 per diluted share in the third quarter of 2025. Cash flow from operations for the third quarter was $42.6 million.
In addition to its GAAP results, the company provided certain measures not calculated according to GAAP. Non-GAAP results exclude stock-based compensation under ASC 718-10, amortization of acquisition-related intangible assets, an accrual for a judgment in a legal matter, a restructuring charge recognized in the first quarter of 2026, and the tax effects of these items. Non-GAAP net income for the third quarter of 2026 was $26.1 million or $0.46 per diluted share compared to $0.37 per diluted share in the prior quarter and $0.36 per diluted share in the third quarter of 2025. A reconciliation of GAAP to non-GAAP financial results and outlook is included with the tables accompanying this press release.
Power Integrations CEO Jen Lloyd commented: "Revenue grew five percent over the prior quarter driven by PowiGaN™ products as well as continued strength in the industrial market, where revenue is up 13 percent year-to-date. We also delivered strong earnings growth in the quarter reflecting our continued focus on expense discipline and profitability. Power is becoming a critical constraint thanks to AI and electrification, calling for dramatic advances in efficiency and power density. Our high-voltage technology and system expertise are well aligned with these challenges, and we are excited about our product roadmap and the opportunities ahead to drive shareholder value."
Power Integrations paid a dividend of $0.215 per share on September 30, 2026 to stockholders of record as of August 31, 2026. A dividend of $0.215 per share will be paid on December 31, 2026, to stockholders of record as of November 30, 2026. The company expects to pay quarterly dividends of $0.22 per share for each of the four quarters of 2027.

•Revenue is expected to be in a range of $118.0 million to $126.0 million.

Note Regarding Use of Non-GAAP Financial Measures
The non-GAAP measures provided in this press release, including non-GAAP earnings per diluted share, non-GAAP net income, non-GAAP gross margin, non-GAAP operating expenses, and non-GAAP operating margin, should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with generally accepted accounting principles (GAAP) in the United States. The non-GAAP financial measures are presented only as supplemental information to understand the Company’s operating results. 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, an accrual for a judgment in a legal matter, a restructuring charge recognized in the first quarter of 2026, and the tax effects of these items. The Company considers these non-GAAP financial measures to be important because they provide additional insight into the Company’s on-going performance; the Company uses these measures in its financial and operational decision-making and, with respect to non-GAAP operating income, 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, to enable more meaningful and consistent period-to-period comparisons, and to facilitate comparability with the results of companies that provide similar measures. Non-GAAP measures have limitations as analytical tools, do not have any standardized meanings and are therefore unlikely to be comparable to similarly titled measures presented by other companies, 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. Reconciliations of non-GAAP measures to GAAP measures are attached to this press release.

Note Regarding Forward-Looking Statements
Certain statements included in this press release that are not historical facts are forward-looking statements within the meaning of the federal securities laws, including the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to future events or the Company’s future financial or operating performance and are sometimes accompanied by words such as “believe,” “continue,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “predict,” “plan,” “may,” “should,” “will,” “would,” “potential,” “seem,” “seek,” “outlook,” and similar expressions that concern the Company’s expectations, strategy, priorities, plans, or intentions, predict or indicate future events or trends, or that are not statements of historical matters. Forward-looking statements are predictions, projections, and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Forward-looking statements in this press release include, without limitation, the Company’s financial and operating performance outlook for the fourth quarter of 2026, the Company's expectations regarding GaN products in development and the markets these products are intended to serve, as well as the Company’s anticipated upcoming dividends, including the timing and amount of such dividends, among others. These statements are based on various assumptions, whether or not identified in this press release. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as and must not be relied on by an investor as a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Actual events and circumstances are very difficult or impossible to predict and will differ from the assumptions. Many actual events and circumstances are beyond the control of the Company. 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 the forward-looking statements in this press release, including but not limited to: (i) the risks that the revenue growth driven by PowiGaN™ products as well as continued strength in the industrial market may not continue to the extent or in the time frame anticipated, or at all; (ii) the risks that the strong earnings growth and continued focus on expense discipline and profitability may not continue to the extent anticipated, or at all; (iii) the risks that the critical constraints to power, due to AI, electrification, or otherwise, and the associated call for dramatic advances in efficiency and power density may not continue to the extent or in the time frame anticipated, or at all; (iv) the risks that the Company's high-voltage technology and system expertise may not be well aligned with these challenges to the extent anticipated, and that the product roadmap and opportunities may not drive shareholder value to the extent or in the time frame anticipated, or at all; (v) the risks that the Company may not be in a position to pay the $0.215 per share dividend on December 31, 2026, or a dividend of $0.22 for each of the quarters in 2027, as currently anticipated, due to unforeseen circumstances; (vi) the risks that the Company may be unable to meet one or more of the elements of the financial outlook for the fourth quarter of 2026, including expected revenue, GAAP and non-GAAP gross margins, GAAP and non-GAAP operating expenses, and GAAP and non-GAAP operating margins due to unforeseen circumstances; (vii) the Company’s ability to forecast its performance; (viii) changes in trade policies, in particular the escalation and imposition of new and higher tariffs, which could reduce demand for end products that incorporate the Company's integrated circuits and/or place pressure on the Company's prices as the Company's customers seek to offset the impact of increased tariffs on their own products; (ix) the Company’s ability to supply products and its ability to conduct other aspects of its business, such as competing for new design wins; (x) 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; (xi) 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; (xii) 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; (xiii) unforeseen costs and expenses, and unfavorable fluctuations in component costs or operating expenses resulting from changes in commodity prices and/or exchange
3
rates; and (xiv) product development delays and defects and market acceptance of the new products. These risks and uncertainties may be amplified by current or future global conflicts and current and potential trade restrictions, trade tensions, and tariffs, all of which continue to cause economic uncertainty. You should carefully consider the foregoing factors and the other risks and uncertainties, including those more fully described in the "Risk Factors" section of the Company’s most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q that the Company has caused to be filed with the U.S. Securities and Exchange Commission, or the SEC, and other documents filed by the Company or that will be filed by the Company from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements in this press release are based only on information currently available to the Company and speak only as of the date they are made.
Investors are cautioned not to put undue reliance on forward-looking statements, and the Company disclaims any obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law. The Company gives no assurance that the Company will achieve any of its expectations.
