Teradyne (TER) Earnings: Q3 2026 Results and Next Report Date

The quarter ended September 27, 2026 and Teradyne published the results on October 27, 2026. Revenue and diluted EPS are shown against Q3 2025, the same quarter a year earlier, which takes seasonal swings out of the comparison. Teradyne 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.

• Teradyne's fiscal quarters end on a Sunday: Q3 2026 ended September 27, 2026 and Q3 2025 ended September 28, 2025.
• Teradyne formed the MultiLane Test Products joint venture on April 8, 2026, taking a 75% stake for about $157.8 million. Its results are in Product Test, and the minority share is why net income attributable to noncontrolling interests appears from Q2 2026.
• On October 6, 2026 Teradyne agreed to make a $300.0 million minority equity investment in FormFactor, expected to close in Q4 2026.

How Teradyne 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.

• Teradyne's Semiconductor Test revenue was $1.1 billion in Q3 2026, up 77% from $606 million in Q3 2025, 82% of total revenue.
• Teradyne's Product Test revenue was $138 million in Q3 2026, up 56% from $88.3 million in Q3 2025, 11% of total revenue.
• Teradyne's Robotics revenue was $95.8 million in Q3 2026, up 28% from $75.1 million in Q3 2025, 7% 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, Teradyne said:

“Guidance for the fourth quarter of 2026 is revenue of $1,250 million to $1,350 million, with GAAP net income attributable to Teradyne of $1.88 to $2.18 per diluted share and non-GAAP net income attributable to Teradyne of $1.95 to $2.25 per diluted share.”

“Non-GAAP guidance excludes acquired intangible asset amortization and amortization on our investment in Technoprobe, as well as the related tax impact on non-GAAP adjustments.”

Teradyne's next report is expected around January 27, 2027, a date estimated from its reporting history that the company has not yet confirmed. This page will show Q3 2026 until those results are out and have been checked against the release.

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 27, 2026

Teradyne reported revenue of $1,306 million for Q3 2026, of which $1,072 million came from Semiconductor Test, $138 million from Product Test and $96 million from Robotics. Revenue rose from $769.2 million a year earlier and was slightly below the $1,329.0 million of Q2 2026. (Teradyne Q3 2026 earnings release, Oct 27, 2026)

Semiconductor Test revenue rose $466.1 million, or 76.9%, which Teradyne said was driven primarily by higher sales in memory and compute related to artificial intelligence applications. Within it, System-on-a-Chip test brought in $676.5 million, Memory test $300.8 million against $128.1 million a year earlier, and Integrated Systems Test, which includes storage and system level test, $94.7 million. (Teradyne Form 10-Q, Q3 2026, Oct 30, 2026)

Product Test, which covers defense and aerospace test, circuit-board test, wireless test and silicon photonics testing, grew 56.4% on AI-related demand plus growth in Wireless and Defense and Aerospace. It now includes the MultiLane Test Products joint venture formed in April 2026. Robotics, collaborative robotic arms and autonomous mobile robots, grew 27.6% to $95.8 million. (Teradyne Form 10-Q, Q3 2026, Oct 30, 2026)

Almost all of Teradyne's revenue is billed to customer sites in Asia. Korea accounted for 32% of Q3 2026 revenue, up from 12% a year earlier, while Taiwan fell to 14% from 37%. China was 21%, Singapore 9% and the United States 8%. (Teradyne Form 10-Q, Q3 2026, Oct 30, 2026)

Teradyne's sales are concentrated. In 2025 its five largest direct customers accounted for 44% of consolidated revenue, and one direct customer of Semiconductor Test accounted for 19%. Two other customers specified 12% and 10% of revenue. (Teradyne Form 10-K, 2025, Feb 19, 2026)

Teradyne's GAAP diluted EPS was $2.17 in Q3 2026, against $0.75 a year earlier, on net income attributable to Teradyne of $342.4 million. Non-GAAP EPS was $2.29. The gap is mostly $7.6 million of amortization of its equity method investment in Technoprobe, $5.3 million of acquired intangible asset amortization, $3.7 million of ERP related expenses and $2.0 million of restructuring and other. (Teradyne Q3 2026 earnings release, Oct 27, 2026)

Gross margin rose to 59.1% from 58.4%, which Teradyne attributed to higher sales and product mix, and GAAP operating income reached $402.0 million, or 30.8% of revenue. The effective tax rate was 14.8%, against 15.8% a year earlier, mainly because of a reduction in U.S. taxation of international income. (Teradyne Q3 2026 earnings release, Oct 27, 2026; Teradyne Form 10-Q, Q3 2026, Oct 30, 2026)

Diluted weighted average shares were 157.5 million, against 159.1 million a year earlier. Teradyne spent $99.3 million on repurchases in Q3 2026 and $173.5 million over the first nine months, buying 0.5 million shares at an average price of $349.62. It paid a dividend of $0.13 a share. (Teradyne Q3 2026 earnings release, Oct 27, 2026; Teradyne Form 10-Q, Q3 2026, Oct 30, 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.

Teradyne gives a one-quarter outlook in its release. For Q4 2026 it guided revenue of $1,250 million to $1,350 million, GAAP EPS of $1.88 to $2.18 and non-GAAP EPS of $1.95 to $2.25. (Teradyne Q3 2026 earnings release, Oct 27, 2026)

Teradyne's non-GAAP guidance excludes acquired intangible asset amortization and amortization on its Technoprobe investment. CEO Greg Smith said demand extended across the AI value chain and that Teradyne approaches 2027 with a more diversified business. (Teradyne Q3 2026 earnings release, Oct 27, 2026)

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

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