Insights

Equity compensation analyst

Routine RSU vesting with tax withholding, no open‑market trading.

The filing shows L. Benjamin Ederington converting 3,809 restricted stock units into the same number of Westlake common shares. Footnotes confirm RSUs convert one-for-one and that this grant dates back to February 17, 2023, vesting after three years.

To satisfy tax obligations from vesting, 978 common shares otherwise issuable were withheld via a transaction coded "F," which is a tax-withholding disposition, not a discretionary market sale. This is standard mechanics for equity compensation and does not itself indicate a change in investment view.

Following these movements, Ederington directly holds 79,090 Westlake common shares. Future compensation-related vestings or grants, if any, would appear in subsequent ownership reports, but this set of transactions appears administrative and aligned with previously granted awards.
