Teradyne, Inc: what insiders have been doing
Teradyne, Inc, classified in the Industry sector, is a listed company based in North Reading, United States, founded in 1960. Its insiders report their share dealings to SEC (Form 4). From 18 October 2025 to 18 October 2026, the disclosure feed for Teradyne, Inc logged 59 filings by 14 insiders.
The flow runs one way only: 11 sales worth €1.4M, from 3 insiders, and no purchase. The largest single trade was a sale of €223k by Mills Regan, published on 27 February 2026.
Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. The legal deadline for a Form 4 is two business days after the transaction. Selling is not necessarily a view on the stock: liquidity needs and diversification are common motives.
With 59 filings in twelve months, the company is more active than the median of 19 filings across the 5,810 companies we follow on the same exchange. Since 2016, the database holds 2 purchases and 65 sales by insiders of the company. For the fiscal year to 31 December 2025, the annual 10-K puts revenue at 3.19 bn USD and net income at 554.0 m USD, and the dividend at 0.48 USD per share.
In the same sector, recent insider purchases at Tennant Co and Butler National Corp also feature in our signals. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.

Founded in 1960, Teradyne has become a global leader in automated test equipment (ATE) and advanced robotics.
