Kaplan Jeffrey A 4

What Happened

• Jeffrey A. Kaplan, EVP and General Counsel of LyondellBasell (LYB), had restricted stock units (RSUs) vest on Feb 22 and Feb 23, 2026. A total of 8,722 RSUs vested (3,218 on Feb 22 and 5,504 on Feb 23). To satisfy tax withholding obligations, the issuer withheld 784 shares on Feb 22 and 1,341 shares on Feb 23, for a total of 2,125 shares withheld — valued at $44,429 and $75,981 respectively (total withheld value $120,410). The net shares delivered to Kaplan were 6,597 (8,722 vested − 2,125 withheld). These filings are routine tax-withholding actions following RSU vesting, not open-market sales.

Key Details

• Transaction dates and amounts:
  • Feb 22, 2026 — 784 shares withheld @ $56.67 = $44,429 (Code F: payment of tax liability/tax withholding).
  • Feb 23, 2026 — 1,341 shares withheld @ $56.66 = $75,981 (Code F).
• Total RSUs vested: 8,722 shares (3,218 on Feb 22; 5,504 on Feb 23).
• Net shares received by insider after withholding: 6,597 shares.
• Footnotes: F1 and F3 confirm the RSU vesting and withholding. Other footnotes list remaining RSU grant tranches from 2023–2025 (unvested portions and future vest dates) as part of the company's long‑term incentive plan.
• Filing timeliness: Report period 2026-02-22; filing date 2026-02-24 — filed within the typical two-business-day window (not marked late).

Context

• Code F indicates these were issuer withholdings to cover tax obligations on vested RSUs, not sales or open-market transactions. This is a routine administrative step following vesting and does not itself signal a change in the insider’s market view.
• For retail investors: RSU vesting increases insider ownership (net of withholdings) but withheld shares are common and expected; purchases are typically more informative about insider sentiment than routine tax withholdings.
