Teradyne Q3 earnings beat expectations but shares slide on profit slowdown and guidance

Teradyne reported adjusted Q3 2026 earnings of $2.29 per share on revenue of $1.31 billion, both ahead of Wall Street estimates. The results showed a 70% year‑over‑year revenue increase and an EPS beat of $0.21, yet earnings fell from $2.47 in Q2. The company’s Q4 guidance of $1.95–$2.25 per share signaled a further sequential decline, and the stock dropped 6%‑6.8% to about $295.

The share price fell sharply despite the beat, reflecting investor concern over the sequential profit slowdown and modest guidance. The lower guidance may pressure the stock until future quarters demonstrate stronger earnings growth.
