Teradyne director trades $198K stock under 10b5-1 plan

Rhea-AI Filing Summary

Teradyne (TER) Form 4 highlights a modest insider trade. On 07/30/2025 director Mercedes Johnson sold 1,875 shares of common stock at $105.73 per share under a pre-arranged Rule 10b5-1 plan adopted 02/03/2025, realizing about $0.2 million in gross proceeds.

After the sale, Johnson directly owns 11,988 shares and indirectly owns 1,876 shares via The Mercedes Johnson Trust, bringing total beneficial ownership to 13,864 shares. No derivative securities were involved. The indirect position reflects a 06/05/2025 transfer to her trust that was exempt from reporting under Rule 16a-13. The filing shows no other transactions and appears routine.

Insights

Securities Analyst

TL;DR: Small 1,875-share sale (~$198k) by director via 10b5-1 plan; ownership still ~13.9k shares; impact neutral.

The transaction represents less than a day’s average trading volume and only a fraction of Johnson’s holdings, suggesting no substantive shift in insider sentiment. Because it was executed under a 10b5-1 plan, it likely reflects pre-scheduled diversification rather than a valuation call. The accompanying trust transfer is administrative and does not change economic exposure. No options or derivatives were exercised. Overall, the filing is routine and should not materially influence TER’s valuation.
