Amkor Technology (AMKR) Earnings: Q3 2026 Results

The quarter ended September 30, 2026 and Amkor Technology published the results on October 26, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison.

• Amkor reports a single operating segment. The split above is its own product-group disclosure: advanced products are flip chip, memory and wafer-level processing with related test services; mainstream products are all other wirebond packaging and related test.

How Amkor Technology 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.

• Amkor Technology's Advanced products revenue was $1.6 billion in Q3 2026, down 3% from $1.7 billion in Q3 2025, 82% of total revenue.
• Amkor Technology's Mainstream products revenue was $359 million in Q3 2026, up 18% from $303 million in Q3 2025, 18% 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 Amkor Technology'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 Oct 26, 2026

Amkor Technology's net sales were $1,991 million in Q3 2026, against $1,987 million a year earlier. Advanced products (flip chip, memory and wafer-level processing with related test services) brought in $1,632 million, down from $1,684 million, and mainstream wirebond packaging and test brought in $359 million, up from $303 million. Packaging services were 88% of net sales and test services 12%. (Amkor Q3 2026 release, Oct 26, 2026)

The end-market mix moved sharply. Communications (smartphones, tablets) fell to 37% of Amkor's net sales from 51% a year earlier, while Computing rose to 26% from 19% and Automotive, industrial and other rose to 22% from 16%. Consumer was 15%. Amkor said Computing and Automotive and industrial both grew 37% on strength in datacenter and ADAS applications. (Amkor Q3 2026 release, Oct 26, 2026; Amkor Form 10-Q, Q3 2026, Oct 27, 2026)

Amkor put the 28% drop in Communications down to the timing of moving SiP programs from its factories in Korea to Vietnam and the related preproduction work. Over the first nine months of 2026 net sales were $5,573 million, up 15.6%, with growth in every end market. (Amkor Form 10-Q, Q3 2026, Oct 27, 2026; Amkor Q3 2026 release, Oct 26, 2026)

Amkor's sales are concentrated. Its top ten customers were 66% of net sales in Q3 2026, against 73% a year earlier. In the 2025 10-K, direct sales to Apple and Qualcomm were 29.8% and 11.1% of full-year net sales. (Amkor Q3 2026 release, Oct 26, 2026; Amkor Form 10-K, 2025, Feb 20, 2026)

Amkor Technology reports one EPS figure, on a GAAP basis. Its only non-GAAP measure in the release is EBITDA, $435 million in Q3 2026 against $340 million a year earlier. Diluted EPS rose to $0.76 from $0.51 as gross margin widened to 18.3% from 14.3%; Amkor attributed the margin gain mainly to a larger share of products sold with lower material content, and materials fell to 50.7% of net sales from 57.5%. (Amkor Q3 2026 release, Oct 26, 2026; Amkor Form 10-Q, Q3 2026, Oct 27, 2026)

Net income attributable to Amkor was $190.6 million on 249,526 thousand diluted shares, against 248,302 thousand a year earlier. Income tax expense was $39.2 million on pre-tax income of $230.2 million, about 17%. Amkor bought back 0.7 million shares for $32.3 million in the first nine months under a $300.0 million program adopted on April 23, 2026, leaving $267.7 million available. (Amkor Q3 2026 release, Oct 26, 2026; Amkor Form 10-Q, Q3 2026, Oct 27, 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.

Amkor Technology gives a numeric outlook in its release. For Q4 2026 it guided net sales of $1.9 billion to $2.0 billion, gross margin of 18.0% to 19.0%, and net income of $160 million to $185 million, or $0.65 to $0.75 per diluted share. It updated full-year 2026 capital expenditures to approximately $2.5 billion, against the approximately $2.5 billion to $3.0 billion it expected in its 2025 10-K. (Amkor Q3 2026 release, Oct 26, 2026; Amkor Form 10-K, 2025, Feb 20, 2026)

Much of that spending is for a new facility in Arizona, where Amkor had incurred $553.3 million of construction costs by September 30, 2026. Amkor has an agreement for up to $407 million of CHIPS Act incentives tied to construction and production milestones, and no funds have been received to date.

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

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