[Form 4] Teradyne, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Form 4 filing overview – Teradyne, Inc. (TER)

On 07/01/2025, director Henry Andrew Chisholm received an equity award of 2,132 restricted stock units (RSUs) under Teradyne’s 2006 Equity and Cash Compensation Incentive Plan. Each RSU represents the right to receive one share of common stock at no purchase cost.

Key terms

• Grant size: 2,132 RSUs
• Acquisition price: $0 (equity compensation, not an open-market purchase)
• Vesting schedule: 100% on the earlier of the 2026 Annual Meeting of Shareholders or the last Thursday in May 2026
• Post-transaction ownership: 2,132 shares held directly

The filing reports no sales, options, or other derivative transactions. This appears to be a routine annual equity grant that aligns the director’s incentives with shareholder interests and has no immediate cash impact on the company.

Insights

Corporate Governance Analyst

TL;DR – Routine RSU grant; neutral market impact.

This Form 4 simply documents the annual equity retainer for non-employee director Henry A. Chisholm. The 2,132-share RSU award, vesting in roughly one year, is typical for boards of Teradyne’s size and does not represent insider buying in the traditional sense. Because no shares were purchased on the open market and the quantity is immaterial to Teradyne’s 2024 year-end share count (~155 million), the disclosure carries negligible valuation impact. It nevertheless signals continued board alignment through stock-based compensation and satisfies Section 16 reporting requirements.
