Teradyne (TER) Q3 2026 Earnings: Compute Test Bottoms, 2027 Ramp Moves Later

Summary
Teradyne's Q3 2026 revenue of $1.306 billion beat guidance as memory, Product Test and Robotics offset a compute test low, while big 2027 compute buys moved to mid-year and later.
Teradyne (TER) Q3 2026 earnings, released in a results press release and on an earnings call on October 28, 2026, beat the company's guidance on revenue and profit, but the AI compute test business fell further than management had indicated in July, and the next large wave of compute purchases moved later [1][2]. Coming into the quarter, four operating questions mattered: how far compute chip test revenue would fall in the second-half lull, whether memory test could keep growing, whether margins would hold after higher operating spending, and whether robotics could reach break-even. Memory test set a record, margins came in above guidance and robotics was profitable in a third quarter for the first time. Compute fell to its low point for the year, and its recovery moved from the first half of 2027 to mid-2027 and later. Overall, the non-compute businesses filled the compute gap, profit conversion was better than expected, and cash conversion slowed because of an inventory build.
Teradyne makes automated test equipment for semiconductors. Its customers are chip designers, foundries, memory makers and outsourced assembly and test companies, and it usually recognizes equipment revenue at shipment. The company also runs Product Test and collaborative Robotics segments. Total third-quarter revenue was $1.306 billion, up 70% year over year [1].
Compute test hit a low, and other chips held SoC revenue
System-on-a-chip (SoC) test revenue fell from $843 million in the second quarter to $676 million in the third quarter, only slightly above the roughly $670 million floor implied by July guidance [2]. Management said businesses outside compute delivered close to 80% of total company sales. On that basis, compute test was about $260 million, or about 40% of SoC, compared with about 70% of SoC in the second quarter [2]. Compute revenue still grew nearly 50% year over year, while automotive and industrial chip test grew nearly 90% and mobile grew 60%; those two lines covered most of the SoC gap [2].
The roughly $330 million decline in compute revenue (an estimate) was absorbed by memory, hard-disk-drive test, Product Test and non-compute SoC, so total company revenue fell only 1.7% from the prior quarter [1][2]. Management said compute bottomed in the third quarter and will start to reaccelerate in the fourth quarter, but the company gave no separate SoC or compute guidance [2].
Large 2027 compute purchases moved to mid-year and later
In July, management said the next surge from these compute customers was expected in the first half of 2027 [3]. On this call, the timing changed: the first hyperscaler's next major ramp is expected in the middle of 2027, the second hyperscaler expects capacity buys in the second half of 2027, and custom-chip programs overall will tend to be more back-half loaded [2]. Because testers have 12 to 16 weeks of lead time, first-half orders and a mid-year ramp may partly overlap, so the actual delay may be smaller than the wording suggests.
Customer qualification is still advancing. In July, the company had one customer in mature dual-vendor operations, one in the fast-follower phase and one in pre-ramp qualification [4]. This quarter, the second hyperscaler passed qualification and moved to fast follower, a third hyperscaler entered initial qualification, and the merchant GPU customer has multiple devices in development [2]. The share path has not reversed; the change is in which quarters the revenue lands. More 2027 compute revenue now falls in the second half, so first-half growth depends more on memory and the other businesses. Management also said it expects each quarter of 2027 to grow sequentially [2].
Conclusion
Teradyne's third-quarter results show a more diversified growth base. Memory test revenue reached $301 million, Product Test $138 million, and Robotics $96 million with a profit, which together offset the compute low [2]. On profit, GAAP gross margin was 59.1% and non-GAAP operating margin was 31.6%, above the company's 28% to 30% guidance [1]. On cash, operating cash flow was $313.6 million, below net income attributable to Teradyne of $342.4 million, because inventories increased by $170.9 million and prepayments and other assets by $165.3 million [1]. Management said about half of the inventory increase is for 2027 demand and half reflects longer component lead times [2].
The company guided fourth-quarter revenue to $1.25 billion to $1.35 billion and gross margin to 57.5% to 58.5% [1][2]. Management expects memory to enter a digestion period in the fourth quarter while compute starts to recover [2]. Three pieces of evidence will test this reading: whether compute recovers in the fourth quarter as management described, whether the 2027 ramp timing slips again, and whether the inventory build turns into revenue rather than continuing to absorb cash. Because the third-quarter 10-Q has not yet been filed, the compute amount is an estimate and product-line figures rely on the earnings call.
