MADDOCK ERNEST E 4

What Happened

• Ernest E. Maddock, a director of Teradyne, Inc. (TER), was issued 2 deferred stock units (DSUs) on June 12, 2026. The units were recorded at $0.00 per unit (total $0) and reported as an "other acquisition" (transaction code J) on a Form 4 filed June 16, 2026.
• This was not an open-market purchase or sale by the director but the issuance of DSUs as a dividend reinvestment — a routine, non-cash acquisition.

Key Details

• Transaction date: 2026-06-12; Form 4 filed: 2026-06-16.
• Amount: 2 DSUs acquired at $0.00 each (total $0).
• Shares owned after transaction: not specified in the provided filing.
• Footnote: DSUs represent deferred stock units issued per the director’s election to receive dividend equivalents as additional DSUs. They are exempt under Exchange Act Rule 16b-3(d) and are settled one-for-one into common stock generally within 90 days after the director leaves board service.
• No indication in the filing that this was part of a 10b5-1 plan or that ordinary insider-sale rules apply (this is a dividend reinvestment).

Context

• DSUs are a common way for non-employee directors to receive equity compensation or dividend equivalents without immediate cash or stock transfer; they typically convert to shares when the director departs the board.
• Because this is a non-cash dividend-related issuance, it should not be interpreted as a market-confidence purchase or sale by the director.
