JOHNSON MERCEDES 4

What Happened

• Mercedes Johnson, a director of Teradyne, was granted 668 restricted stock units (RSUs) on May 8, 2026. The Form 4 reports an acquisition (award) of 668 shares at $0.00, with a reported total value of $0 — these RSUs convert to one share of common stock each when vested. This is an equity compensation award (not an open‑market purchase or sale).

Key Details

• Transaction date: May 8, 2026. Transaction type/code: Award/Grant (A). Amount: 668 RSUs; Price: $0.00; Reported value: $0.
• Vesting: RSUs are time‑based and will vest in full on the earlier of May 8, 2027 or the date of Teradyne’s 2027 Annual Meeting of Shareholders (footnote F1).
• Shares owned after transaction: The filing does not state total post‑transaction holdings; note footnote F2 indicates shares are held by The Mercedes Johnson Trust (the Reporting Person is trustee and sole beneficiary).
• Filing timeliness: Report filed May 12, 2026 for the May 8, 2026 grant — filed within the typical Form 4 reporting window.

Context

• RSUs are a common form of executive/director compensation that convert to actual shares when they vest; they are awards rather than purchases and do not by themselves indicate buying or selling sentiment.
• Footnote F2 shows existing holdings are in a trust (not a separate purchase), which is common for estate and tax planning.
