[Form 4] Teradyne, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Teradyne President & CEO Gregory S. Smith filed a Form 4 reporting the sale of 554 common shares on 30 Jul 2025 at an average price of $105.73, yielding proceeds of roughly $58 k. The trade was executed under a Rule 10b5-1 plan adopted 4 Feb 2025, signalling it was pre-scheduled rather than opportunistic.

Following the transaction, Smith directly owns 97,546.995 shares, which already include 98.7673 shares purchased via the Employee Stock Purchase Plan on 30 Jun 2025. No derivative security activity was reported.

The sale represents about 0.6 % of his direct holdings and is immaterial relative to Teradyne’s total shares outstanding, suggesting limited market impact. No additional insider transactions or corporate events were disclosed in this filing.

Insights

Securities Analyst

TL;DR: Minor CEO sale (0.6 % of stake) under 10b5-1; neutral to stock.

The transaction involves just 554 shares, worth ≈ $58 k, compared with Smith’s post-sale holding of 97.5 k shares. Because it was executed under a pre-arranged 10b5-1 plan, the sale carries minimal informational content about management’s view of valuation. Volume is negligible relative to average daily trading and total outstanding shares, so I view the filing as routine, with no valuation-changing insight.

Corporate Governance Expert

TL;DR: Pre-planned sale aligns with best-practice governance; no red flags.

Use of a 10b5-1 plan lowers litigation risk and signals compliance discipline. The modest size (<1 % of personal stake) indicates continued alignment of CEO interests with shareholders. There are no accompanying derivative trades or pattern of large disposals, so governance and incentive structure remain intact. Overall impact: neutral.
