Herweck Peter 4

What Happened
Peter Herweck, a non-employee director of Teradyne, acquired 5 deferred stock units (DSUs) on March 13, 2026. The filing records the acquisition at $0.00 per unit (total $0) because these units were issued as dividend equivalents rather than a purchase. This is an acquisition via dividend reinvestment rather than a market purchase.

Key Details

• Transaction date: 2026-03-13. Form 4 filed: 2026-03-17 (timely filing).
• Transaction code: (J) — "Other acquisition or disposition"; footnote clarifies these are DSUs issued in lieu of cash dividends.
• Shares/units acquired: 5 DSUs at $0.00 each (total reported $0).
• Shares owned after transaction: not specified in the provided filing details.
• Exemption: DSU acquisition is exempt under Exchange Act Rule 16b-3(d) per the filing footnote.

Context
DSUs are a deferred compensation instrument for non-employee directors; Herweck elected to receive dividend payments as additional DSUs. These DSUs are generally converted one-for-one into Teradyne common stock and delivered within about 90 days after the director stops serving. Such dividend-based DSU issuances are routine and do not necessarily indicate a buy/sell signal.
