ROOKE PAUL A 4

What Happened
Paul A. Rooke, a director of Plexus Corp. (PLXS), had 1,370 restricted stock units (RSUs) vest and convert into 1,370 shares on February 3, 2026. The Form 4 shows a simultaneous disposal of 1,370 shares (derivative), with prices listed as N/A and no gross dollar amount reported. This transaction represents receipt of an equity award rather than an open-market purchase or sale.

Key Details

• Transaction date: February 3, 2026 (Form 4 filed February 5, 2026 — timely).
• Acquired: 1,370 shares via exercise/conversion of derivative (code M); price N/A.
• Disposed: 1,370 shares (derivative); price N/A.
• Shares owned after transaction: not specified in the provided filing excerpt.
• Footnote F1: The RSUs were granted under the Plexus 2024 Omnibus Incentive Plan; each RSU converted to one share and vested/settled on Feb 3, 2026.
• Filing timeliness: Report filed two days after the transaction date, consistent with Form 4 reporting rules.

Context
This was an award vesting/settlement event (not a market purchase). The matching disposal is commonly used to satisfy tax-withholding obligations when RSUs vest, so it often does not reflect a discretionary sale of newly vested shares. For retail investors, RSU vesting is routine compensation activity and should be viewed differently from executives buying or selling shares in the open market.
