Power Integrations (POWI) Earnings: Q3 2026 Results and Next Report Date

The quarter ended September 30, 2026 and Power Integrations published the results on November 4, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Power Integrations reports EPS two ways: GAAP, under the accounting rules every US filer follows, and non-GAAP, which leaves out items the company considers outside its operating results. The release reconciles the two, and when they diverge, the reconciliation says why.

• Q3 2025 GAAP results included $13.6 million of stock-based compensation from modifying a former CEO's equity awards and a $725 thousand litigation accrual, both recorded in other operating expenses, which is why Q3 2025 GAAP EPS was a loss of $0.02.
• Power Integrations does not report segments. The table shows the sales-channel split from its 10-Q.

How Power Integrations splits revenue in its own release, under its own labels, for Q3 2026 against Q3 2025. Indented lines are parts of the line above them.

• Power Integrations's Sales to distributors revenue was $84.3 million in Q3 2026, up 2% from $82.3 million in Q3 2025, 67% of total revenue.
• Power Integrations's Sales to OEMs and CMs revenue was $41.2 million in Q3 2026, up 12% from $36.7 million in Q3 2025, 33% of total revenue.

Segment lines are the figures writers cite most often, because they show where the growth in a quarter came from. Companies redraw their segments from time to time and restate the prior year to match, so a year-ago figure here can differ from the one printed a year ago. When that has happened, the note above says so.

Each quarter keeps its own page with the figures as reported, so a link to one stays pointed at the same numbers after the next report.

• Q3 2026 (this page), reported Nov 4, 2026

Power Integrations sells high-voltage power conversion chips, including its PowiGaN gallium nitride products, that turn high-voltage AC power into the low-voltage DC used by smartphones, appliances, industrial controls, smart meters and other electronics. Net revenue was $125.5 million in Q3 2026, up five percent from the prior quarter and six percent from $118.9 million a year earlier. (Power Integrations Q3 2026 release, Nov 4, 2026; Power Integrations Form 10-K, 2025, Feb 6, 2026)

Industrial is now the largest end market, at 43% of Q3 2026 revenue against 42% a year earlier. Consumer was 32% (34% a year earlier), Computer 13% and Communications 12% (11%). The 10-Q puts the year-over-year increase down to higher sales in the industrial and communications end markets, and the CEO said industrial revenue is up 13 percent year to date. (Power Integrations Form 10-Q, Q3 2026, Nov 5, 2026; Power Integrations Q3 2026 release, Nov 4, 2026)

Most of the end products are built in Asia, which took approximately 81% of net revenue, against 83% a year earlier. Sales outside the United States were $122.9 million of the $125.5 million total. (Power Integrations Form 10-Q, Q3 2026, Nov 5, 2026)

Power Integrations sells mainly through distributors, which took $84.3 million, or approximately 67% of net revenue, with direct sales to OEMs and power-supply contract manufacturers making up the rest. Its top ten customers were approximately 82% of net revenue, and the largest single customer was 32%. About 21% of revenue related to one OEM that buys through Power Integrations' contract-manufacturer customers. (Power Integrations Form 10-Q, Q3 2026, Nov 5, 2026)

Power Integrations earned $18.3 million in Q3 2026, or $0.32 per diluted share, against a net loss of $0.02 per share a year earlier. Q3 2025 had carried $13.6 million of stock-based compensation tied to a former CEO's retirement arrangements and a litigation accrual in other operating expenses. In Q3 2026 that line was income of $2.0 million, including a $1.8 million release of liability on settling a litigation matter. (Power Integrations Q3 2026 release, Nov 4, 2026; Power Integrations Form 10-Q, Q3 2026, Nov 5, 2026)

Non-GAAP EPS was $0.46, against $0.36. Power Integrations' non-GAAP figures exclude stock-based compensation, amortization of acquisition-related intangibles, the legal judgment accrual and its later reversal, the restructuring charge from the first quarter of 2026, and the tax effects of these items. Stock-based compensation unrelated to restructuring was $9.6 million in the quarter. (Power Integrations Q3 2026 release, Nov 4, 2026)

Diluted shares were 56,608 thousand, against 55,796 thousand a year earlier. Power Integrations had no authorization to repurchase shares at September 30, 2026. It paid a dividend of $0.215 per share and plans quarterly dividends of $0.22 per share in 2027. (Power Integrations Q3 2026 release, Nov 4, 2026; Power Integrations Form 10-Q, Q3 2026, Nov 5, 2026)

Diluted EPS divides net income by the weighted average number of shares outstanding in the quarter, plus the shares that options and other equity awards could add. Buybacks shrink that count and lift EPS for the same profit; share issuance and stock awards enlarge it.

Power Integrations guides one quarter ahead in its release. For Q4 2026 it expects revenue of $118.0 million to $126.0 million, GAAP gross margin of 54.0 to 55.0 percent, GAAP operating expenses of $53.0 million to $54.0 million, and a GAAP operating margin of 10.0 to 12.0 percent. On a non-GAAP basis it expects operating expenses of $42.5 million to $43.5 million and an operating margin of 19.0 to 21.0 percent. (Power Integrations Q3 2026 release, Nov 4, 2026)

A consensus figure is the average of the models published by the analysts who cover Power Integrations, collected by a data provider and revised up to the day of the report. A quarter that lands above it says how expectations were set as much as how the business did, and the share price on the day also reflects the guidance and the lines no consensus covers.

The consensus figures on this page are Yahoo Finance's, as pulled on the date shown. Each comes with the number of analysts behind it; the smaller that number, the more one revised estimate can move the average.

The figures below are the ones Power Integrations's own release and filings put weight on for Q3 2026, with the latest reported value for each.

What the quarter means for a holding is a separate question from what it reported. The case for and against owning POWI is on is POWI a buy or a sell?, what analysts expect next is on the POWI forecast, and what the company does is on the Power Integrations (POWI) stock page.

Every number on this page can be traced to a document Power Integrations published. Checking one takes a couple of minutes, and it is worth doing before you quote a figure anywhere.

• The results release is the document linked in the source line above. Companies publish it on their investor relations site at the moment results go out, and it carries the headline tables: revenue, operating income, net income and EPS for the quarter and the year-ago quarter.
• The same release is filed with the SEC as Exhibit 99.1 to a Form 8-K under Item 2.02, usually on the day of the report. The SEC copy does not change after the fact, which makes it the safer thing to link when you cite a number.
• The quarterly report (Form 10-Q) follows within a few weeks and carries the full financial statements, the segment note and management's discussion of what changed. The fourth quarter is covered by the annual report (Form 10-K) instead.
• Restated comparisons are flagged in the notes on this page. When a company redraws its segments or changes how it adjusts EPS, it restates the year-ago column, so the year-ago figure in a new release can differ from the one printed a year ago. This page always uses the comparison in the newer release, because that is the like-for-like one.
