Diodes Incorporated (DIOD) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Diodes Incorporated published the results on November 5, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Diodes Incorporated 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.

• Diodes reports a single operating segment. The regional split shown is from the 10-Q and is based on where products were shipped.
• Diodes acquired ElevATE Semiconductor on August 27, 2026, so Q3 2026 includes about one month of ElevATE.

How Diodes Incorporated 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.

• Diodes Incorporated's Asia revenue was $419 million in Q3 2026, up 36% from $308 million in Q3 2025, 79% of total revenue.
• Diodes Incorporated's Europe revenue was $61.7 million in Q3 2026, up 34% from $46.2 million in Q3 2025, 12% of total revenue.
• Diodes Incorporated's Americas revenue was $51.9 million in Q3 2026, up 36% from $38.1 million in Q3 2025, 10% 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.

From the earnings release

In its Q3 2026 release (Gary Yu, President and CEO), Diodes Incorporated said:

“For the fourth quarter of 2026, we expect to extend our strong growth momentum with revenue expected to increase to approximately $550 million, plus or minus 3%, representing a 40.4% increase year-over-year and a 3.2% increase sequentially at the mid-point.”

“Non-GAAP gross margin is expected to expand to 37.0%, plus or minus 1%.”

“Non-GAAP adjusted EPS is expected to be $1.35, plus or minus $0.10.”

We do not hold a confirmed date for Diodes Incorporated'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 5, 2026

Diodes Incorporated sells analog, power and discrete semiconductors into the automotive, industrial, computing, consumer electronics and communications markets. Q3 2026 revenue was a record $532.6 million, up 35.8% from $392.2 million a year earlier and 19.5% from $445.5 million in Q2 2026. (Diodes Q3 2026 release, Nov 5, 2026)

Diodes said automotive revenue reached a record 22% of revenue, up 60% year over year, industrial revenue grew 50% year over year and 26% sequentially, and computing revenue grew 33%, driven by AI data center demand. Its chief executive attributed the sequential growth to automotive market share gains, broader industrial demand and AI-related computing, and said global point-of-sale (POS) sales were a record, up more than 30% year over year. (Diodes Q3 2026 earnings presentation, Nov 5, 2026; Diodes Q3 2026 release, Nov 5, 2026)

Most sales go through distributors: $358.5 million in Q3 2026, against $174.1 million of direct sales. Two broad-based distributors each accounted for 10% or more of net sales, with $72.4 million and $61.0 million in the quarter. (Diodes Form 10-Q, Q3 2026, Nov 5, 2026)

By shipment destination, Asia took $419.0 million of the quarter's sales, Europe $61.7 million and the Americas $51.9 million. Shipments to China alone were $269.3 million, against $170.6 million a year earlier; Singapore was $52.2 million and Taiwan $32.8 million. (Diodes Form 10-Q, Q3 2026, Nov 5, 2026)

Diodes closed its acquisition of ElevATE Semiconductor, which makes integrated circuits for automated test equipment, on August 27, 2026. Diodes expects ElevATE to contribute about $50 million of revenue in its first 12 months. (Diodes Form 10-Q, Q3 2026, Nov 5, 2026; Diodes Q3 2026 earnings presentation, Nov 5, 2026)

Diodes Incorporated's GAAP diluted EPS was $0.95 in Q3 2026, against $0.31 a year earlier, and non-GAAP EPS was $1.18. The largest item between them was a $7.9 million after-tax unrealized loss on investments, which Diodes excludes; the non-GAAP figure also leaves out $4.2 million of acquisition-related intangible amortization and $1.4 million of acquisition costs, and removes a $3.0 million gain on the disposal of a subsidiary. (Diodes Q3 2026 release, Nov 5, 2026)

GAAP gross profit margin was 36.1%, up 540 basis points from 30.7%, which Diodes put down to higher factory loading from new capacity, product mix and pricing. Both GAAP and non-GAAP net income include about $7.4 million of after-tax share-based compensation, worth $0.16 a share. The effective tax rate was 23.2%, against 18.7% a year earlier, because of nondeductible investment losses. (Diodes Q3 2026 release, Nov 5, 2026; Diodes Form 10-Q, Q3 2026, Nov 5, 2026)

Diluted shares were 46,247 thousand, against 46,437 thousand a year earlier. In August 2026 Diodes issued $375.0 million of 0.00% convertible senior notes due 2031 and, alongside the pricing, repurchased 360,119 shares at $97.19 for about $35.0 million. (Diodes Q3 2026 release, Nov 5, 2026; Diodes 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.

Diodes Incorporated guides one quarter ahead in its release. For Q4 2026 it expects revenue of about $550 million, plus or minus 3%, a 40.4% increase year over year and 3.2% sequentially at the midpoint, non-GAAP gross margin of 37.0%, plus or minus 1%, and non-GAAP adjusted EPS of $1.35, plus or minus $0.10. It gives no GAAP EPS outlook. (Diodes Q3 2026 release, Nov 5, 2026)

The chief executive also said full-year 2026 revenue should rise about 30% over 2025 at the midpoint. The investor slides list a three-year target, set for 2028, of $2B revenue and non-GAAP EPS of $4.00 or more. (Diodes Q3 2026 release, Nov 5, 2026; Diodes Q3 2026 earnings presentation, Nov 5, 2026)

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

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