Multiply Labs, a robotics firm under Teradyne’s Universal Robots division, announced a breakthrough in automated biomanufacturing. Their robotic system reduces cell therapy production costs by 74%, enabling scalable, sterile processes for personalized cancer treatments. This innovation leverages UR’s collaborative robots to replicate manual workflows with enhanced efficiency and compliance, potentially accelerating regulatory approvals and reducing re-approval costs.

Teradyne also unveiled the Magnum 7H, a next-generation memory tester for high-bandwidth memory (HBM) devices used in AI servers. The product supports HBM2E to HBM4E standards and has begun volume shipments. Meanwhile, Universal Robots launched the UR15, its fastest cobot with 5 m/s TCP speed, targeting industries like automotive and electronics. These advancements underscore Teradyne’s focus on expanding its robotics and semiconductor testing solutions.

Recent financial results showed mixed performance. Q2 2025 revenue fell to $651.8 million, down 11% year-over-year, but non-GAAP EPS of $0.57 exceeded estimates. The company attributed strength to AI-driven chip testing demand and robotics sales. However, Q3 guidance of $740 million revenue fell short of expectations, reflecting macroeconomic uncertainties.

A backtested strategy of holding the top 500 stocks by daily trading volume from 2022 to 2025 yielded a 7.61% total return with a 1.98% average daily gain.
