MADDOCK ERNEST E 4

What Happened

• Ernest E. Maddock, a director of Teradyne, was awarded 668 restricted stock units (RSUs) on May 8, 2026. The Form 4 shows the grant as 668 shares at $0.00 (code A — award/grant), reported on May 12, 2026. The filing lists the acquisition value as $0 because RSUs are awards that convert to shares only upon vesting/settlement.

Key Details

• Transaction date: 2026-05-08; Filing date: 2026-05-12 (Form 4 accession 0000904454-26-000264).
• Reported terms: 668 RSUs granted, reported acquisition price $0.00 (award).
• Shares owned following the reported transaction: not specified in the filing.
• Footnote: These are time-based RSUs under Teradyne’s 2006 Equity and Cash Compensation Incentive Plan. Each RSU represents the right to receive one share of common stock and will vest in full on the earlier of May 8, 2027 or the date of the 2027 Annual Meeting of Shareholders.
• Timing note: The Form 4 was filed four days after the transaction date; Section 16 filings are generally required within two business days, so this filing was submitted after that typical two-day window.

Context

• RSU grants are equity awards that become actual shares only when they vest; they are not an open-market purchase or sale and do not necessarily indicate immediate buying or selling sentiment. Grants to directors are common as compensation for service and often include time-based vesting.
