Teradyne stock rises as revenue doubles in latest quarter

Teradyne Inc. (US8807701029) traded at USD 398.69 on Nasdaq at the close on September 22, 2026, after the stock gained USD 17.15, or 4.49 percent, in the session. The latest market data place the company at a market capitalization of USD 62.33 billion, while the 52-week range runs from USD 128.59 to USD 487.91.

Revenue reaches USD 1.33 billion

The operating picture is anchored by Teradyne's latest reported quarter, released on July 29, 2026. According to MarketBeat, revenue reached USD 1.33 billion, compared with analyst expectations of USD 1.22 billion, while earnings per share came to USD 2.47 versus consensus of USD 2.09.

The year-on-year comparison is unusually large: quarterly revenue was up 103.9 percent from the same quarter of the previous year, and EPS rose from USD 0.57 to USD 2.47. Net margin for the reported quarter was 25.77 percent, according to MarketBeat.

Six gains lift the shares

The price reaction has built over several sessions rather than appearing as a single-day move. Trefis reported on September 23, 2026, that Teradyne shares had recorded six consecutive positive sessions and were up 21 percent over that stretch, with the stock trading near USD 398.69 as of September 22, 2026.

That advance leaves the shares below the reported 52-week high of USD 487.91 by USD 89.22, while the market capitalization has reached USD 62.33 billion as of September 23, 2026. The valuation remains demanding on the available figures: the price-to-earnings ratio was reported at 54.69, and the PEG ratio at 0.77.

Stock remains below yearly high

Teradyne stock closed at USD 398.69 on Nasdaq on September 22, 2026. The combination of USD 1.33 billion in quarterly revenue, a 103.9 percent year-on-year increase and EPS of USD 2.47 gives the recent price strength a clearly quantified operating backdrop.
