onsemi (ON) Earnings: Q3 2026 Results

The quarter ended October 2, 2026 and onsemi published the results on November 2, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. onsemi 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.

• PSG is the Power Solutions Group, AMG the Analog and Mixed-Signal Group and ISG the Intelligent Sensing Group.
• onsemi's Q3 2026 ended October 2, 2026 and its Q3 2025 ended October 3, 2025. The 10-Q says some prior-period end-market revenue was reclassified to match the current presentation.

How onsemi 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.

• onsemi's PSG revenue was $890 million in Q3 2026, up 21% from $738 million in Q3 2025, 52% of total revenue.
• onsemi's AMG revenue was $597 million in Q3 2026, up 2% from $583 million in Q3 2025, 35% of total revenue.
• onsemi's ISG revenue was $235 million in Q3 2026, up 2% from $230 million in Q3 2025, 14% 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.

We do not hold a confirmed date for onsemi's next report. Companies post the date on their investor relations site a few weeks ahead, usually with the time of the conference call.

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 2, 2026

onsemi reports three segments. In Q3 2026 the Power Solutions Group (PSG) brought in $889.9 million of the $1,722.3 million total, 51.6% of revenue, the Analog and Mixed-Signal Group (AMG) $597.3 million and the Intelligent Sensing Group (ISG) $235.1 million. PSG revenue rose $152.3 million, about 21%, on increases of $64.9 million in industrial, $71.3 million in AI data center and $31.4 million in other end-markets, offset by a $15.3 million decrease in automotive. (onsemi Form 10-Q, Q3 2026, Nov 2, 2026)

Automotive is still onsemi's largest end-market at $776.7 million, against $787.3 million a year earlier. Industrial revenue was $466.8 million against $426.3 million, and AI data center revenue was $180.2 million against $65.6 million. The 10-Q puts the automotive decline down to lower sales volume after onsemi reallocated supply to the industrial and AI data center end-markets. The CEO said in the release that AI data center revenue grew 39% sequentially and 175% year-over-year. (onsemi Form 10-Q, Q3 2026, Nov 2, 2026; onsemi Q3 2026 release, Nov 2, 2026)

AMG revenue rose $14.0 million, about 2%, as increases of $18.4 million in automotive and $43.3 million in AI data center were offset by decreases of $41.6 million in industrial and $6.1 million in other end-markets. ISG revenue rose $5.1 million, about 2%, with automotive down $13.7 million. By product technology, intelligent power brought in $918.8 million against $792.8 million a year earlier. (onsemi Form 10-Q, Q3 2026, Nov 2, 2026)

onsemi sells mostly through distributors: $1,058.6 million of Q3 2026 revenue went through that channel, and one distributor accounted for about 15% of total revenue, up from 12% a year earlier. By billing location, Hong Kong was $567.8 million (33.0% of revenue), Singapore $436.9 million (25.4%), the United Kingdom $316.7 million and the United States $294.3 million, down from $340.5 million. (onsemi Form 10-Q, Q3 2026, Nov 2, 2026)

The 10-K describes intelligent power technology based on silicon, silicon carbide and GaN as a central focus of the portfolio, supplied as bare die, packaged discrete products and complete power modules. It names Infineon, STMicroelectronics, Wolfspeed, ROHM Semiconductor and Nexperia as PSG's primary competitors. (onsemi Form 10-K, 2025, Feb 9, 2026)

onsemi's GAAP diluted EPS was $0.79 in Q3 2026 and its non-GAAP diluted EPS $0.90. Non-GAAP net income of $354.0 million adds back $40.1 million of special items to GAAP net income of $313.9 million, including $11.7 million of intangible amortization, $7.5 million of third-party acquisition and divestiture costs, $4.6 million of restructuring and a $22.3 million adjustment to income taxes. The non-GAAP share count of 392.2 million also leaves out 5.1 million dilutive shares attributable to the convertible notes. (onsemi Q3 2026 release, Nov 2, 2026)

Tax was a large part of the year-over-year comparison. onsemi recorded an income tax provision of $84.9 million, an effective rate of 21.3%, against $17.7 million and 6.5% a year earlier, when it recognized a discrete benefit from a return-to-provision adjustment after finalizing its 2024 U.S. federal income tax return. (onsemi Form 10-Q, Q3 2026, Nov 2, 2026)

Buybacks slowed sharply in the quarter. onsemi repurchased 0.3 million shares for $19.9 million, against 6.1 million shares for $325.0 million in Q3 2025, and 9.1 million shares for $697.4 million over the nine months. About $5.3 billion remained under the $6.0 billion program that runs through December 31, 2028. GAAP diluted weighted average shares were 397.3 million, against 408.0 million a year earlier. (onsemi Form 10-Q, Q3 2026, Nov 2, 2026; onsemi Q3 2026 release, Nov 2, 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.

onsemi publishes a numeric outlook table in each release. For Q4 2026 it guided revenue of $1,715 to $1,815 million, GAAP gross margin of 41.4% to 43.4% (non-GAAP 41.5% to 43.5%), and diluted EPS of $0.88 to $1.00 on a GAAP basis and $0.95 to $1.07 non-GAAP, on 397 million GAAP and 392 million non-GAAP diluted shares. The CEO said Q3 revenue, gross margin and EPS exceeded the midpoint of the prior guidance. (onsemi Q3 2026 release, Nov 2, 2026)

Two pending deals sit outside that outlook. onsemi revised its planned acquisition of Synaptics to about $5.7 billion in cash, or $123.00 per Synaptics share, from $7 billion in stock under the prior agreement, and agreed to acquire Ferric, which it said raised its AI data center 2030 revenue target by $500 million to greater than $3 billion.

A consensus figure is the average of the models published by the analysts who cover onsemi, 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 onsemi'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 ON is on is ON a buy or a sell?, what analysts expect next is on the ON forecast, and what the company does is on the onsemi (ON) stock page.

Every number on this page can be traced to a document onsemi 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.
