Foley Kimberly A 4

What Happened

• Kimberly A. Foley, EVP, Global O&P and Refining at LyondellBasell (LYB), had restricted stock units (RSUs) automatically vest on Feb 22 and Feb 23, 2026. A total of 8,931 RSUs vested (3,365 on Feb 22; 5,566 on Feb 23). To satisfy tax withholding obligations the issuer withheld and “disposed” 820 shares on Feb 22 at $56.67 (proceeds/value $46,469) and 1,356 shares on Feb 23 at $56.66 (value $76,831), totaling 2,176 shares withheld (~$123,300). This was a routine tax-withholding disposition tied to RSU vesting rather than an open-market sale.
