Karlin Bridget E 4

What Happened

• Bridget E. Karlin, a director of LyondellBasell Industries N.V. (LYB), was granted 2,321 restricted stock units (RSUs) on May 21, 2026 (reported as an award at $0.00). Separately, 2,917 RSUs automatically vested on May 22, 2026; 521 of those vested shares were withheld by the issuer to satisfy tax withholding obligations (disposed) at a reported per-share value of $69.72, totaling $36,324.
• The 2,321 RSUs granted on May 21, 2026 vest on May 21, 2027. The withholding transaction is routine tax withholding (Form 4 code F), not an open-market sale.

Key Details

  • 521 shares were withheld on May 22 to satisfy tax obligations.
• Shares owned after transaction: the filing does not disclose Karlin’s total shareholdings after these transactions.
• Filing timeliness: Form filed May 26, 2026 for transactions on May 21–22, 2026. The May 21 grant appears to have been filed one day after the two-business-day deadline for that transaction; the May 22 vesting was filed within its two-business-day window.

Context

• RSUs are compensation awards that convert to shares on vesting; the withheld 521 shares were retained by the company to cover taxes rather than sold on the open market. Such withholdings are routine and generally reflect tax obligations, not a directional trading signal. This filing documents compensation and tax withholding rather than a discretionary buy or sell by the director.
