Szwejbka Scott Thomas 4

What Happened

• Scott Thomas Szwejbka, Senior Vice President and HIP Segment Head at Westlake Corp (WLK), had 977 restricted stock units (RSUs convert to common stock 1:1) vest and convert into 977 shares on Feb 17, 2026. Of those, 295 shares were withheld to satisfy tax withholding, valued at $98.95 per share (≈ $29,190). Net shares issued to the reporting person: 682 shares.
• This was not a market purchase or trading decision but a routine vesting/settlement of previously granted RSUs; the withholding of shares to pay taxes is a standard administrative disposition.

Key Details

• Transaction dates: conversion/vesting recorded Feb 17, 2026; tax-withholding disposition recorded Feb 18, 2026; Form 4 filed Feb 19, 2026 (filed within the typical two-business-day window).
• Prices/values: tax-withheld 295 shares × $98.95 = $29,190 reported disposition value. RSU conversion recorded at $0.00 per share (award conversion).
• Shares owned after transaction: not stated in the provided filing excerpt.
• Footnotes: F1 — RSUs convert one-for-one to common stock. F2 — these 977 RSUs were originally granted on Feb 17, 2023 with a three-year vesting. F3 — shares otherwise issuable were withheld to satisfy tax obligations arising from RSU vesting.
• Transaction codes: M = exercise/conversion of derivative (RSU vesting/conversion); F = payment of exercise price or tax liability (share withholding).

Context

• RSU vesting and withholding for taxes is a routine corporate administrative event and does not by itself indicate buying or selling intent in the open market. The transaction represents receipt of vested equity, with a portion surrendered to cover tax obligations (a form of cashless withholding).
