Teradyne (NASDAQ:TER) delivered a second quarter that beat almost every number Wall Street had penciled in. On July 28, the company reported revenue of $1,329 million, up 104% from $652 million a year earlier, while non-GAAP EPS jumped to $2.47 from $0.57. Earnings beat average analyst estimates by $0.42 a share, and revenue landed roughly $110 million above forecasts. It marked Teradyne’s second straight quarter of record revenue, above the high end of its own guidance. That kind of jump raises an obvious question: how much room is left to keep growing at this pace?
Bull Case: A Business Firing On Every Cylinder
CEO Greg Smith credited the strategy of capturing test and robotics opportunities “from wafer to AI data center,” and the segment numbers back him up. Memory revenue hit a record $212 million, powered by continued DRAM strength and a rebound in NAND final test, while the System-on-Chip/SoC test business brought in $843 million. Product Test revenue rose 26% year over year to $107 million, and Robotics climbed 33% to $100 million.
Third quarter guidance also topped expectations: revenue of $1,200 million to $1,300 million and non-GAAP EPS of $1.85 to $2.15, both above the $1.03 billion and $1.44 that analysts had modeled. Gross margin reached 59.8%, up 250 basis points from a year earlier, and free cash flow totaled $378 million for the quarter and $579 million for the first half of 2026, up 150% year-over-year. Management also noted that test spending as a share of overall wafer fab equipment investment has climbed from roughly 4% in 2023 to about 8% now and should settle between 7% and 9%.
Bear Case: The Cracks Underneath A Blowout Quarter
Not everything was clean. Gross margin will keep moving sequentially as product mix shifts, and the third quarter guide already carries a 130 basis point headwind tied partly to memory, adding pressure into 2027. In the competitive SoC test market, executives expect only modest incremental share gains rather than a breakout. There is also real uncertainty in how closely test spending tracks wafer fab equipment investment, since the relationship can include time lags that make near-term revenue harder to forecast. Robotics grew 33% in the quarter, but on the earnings call it drew far less attention than the semiconductor businesses, and its longer-term trajectory remains less defined. Supply chain pressure is also pushing Teradyne toward dual vendor strategies to protect capacity.
The stock still gave back much of its post-earnings pop on July 29, rising just 3.3% by early afternoon after being up as much as 16.1% earlier that day, as broader weakness pulled the S&P 500 and Nasdaq Composite down 0.9%.
What The Market Already Believes
Hedge fund ownership of Teradyne climbed from 77 funds to 80 between the two most recent quarters, a sign of accumulating conviction. Short interest sits at 5.39% of float, enough to reflect a real bear camp but far from the double-digit levels that signal heavy skepticism. As of August 11, the stock trades at 39.06 times forward earnings, a multiple that already assumes the AI-driven growth keeps compounding.
The Question Still Left Open
Teradyne’s second quarter shows a company genuinely riding the AI buildout, with revenue and profit compounding well beyond last year’s pace. The open question is less whether that cycle is real and more how long it keeps this intensity, especially with memory margins already under pressure heading into 2027. A test to WFE ratio that keeps climbing toward the high end of management’s 7% to 9% range would keep the growth case intact.
