Teradyne Inc. (US8807701029) closed the latest NASDAQ session at a record 471.96 US dollars per share after a double-digit move on Thursday. The testing specialist rallied as investors reacted to a blowout earnings report from key customer Micron Technology, which also sits in the NASDAQ-100.

Micron’s numbers lift Teradyne

According to a recent market report, Teradyne shares surged 10.47 percent on Thursday, finishing the session at 471.96 dollars after touching an intraday high of 472.37 dollars, both new all-time highs for the stock. The move followed Micron Technology’s fiscal third-quarter results, where the memory maker reported net income of 28.2 billion dollars versus 1.88 billion dollars a year earlier, a jump of around 1,400 percent.

Micron’s revenues in the same quarter rose to 41.456 billion dollars from 9.3 billion dollars in the prior-year period, an increase of roughly 346 percent, driven by strong demand for AI-related memory products. Because Micron is an important customer for Teradyne’s memory and system-on-chip test equipment, the earnings surprise has been interpreted by investors as a signal of robust test demand across the semiconductor cycle.

Analyst targets lag the fresh high

On MarketBeat data, Teradyne last closed at 471.96 dollars on NASDAQ on 25 June, with after-hours trading indicating a further uptick to around 475.75 dollars.

An analysis published by research platform Tikr notes that some models see a mid-case fundamental value for Teradyne around 1,025 dollars per share, indicating a wide dispersion between more optimistic views and the Street’s 390 dollar average target. The same piece highlights that Teradyne’s last earnings reaction in late April 2026 was a decline of about 19.4 percent, underlining how sensitive the stock can be around quarterly reports.
