Westlake (WLK) Director Catherine Chao Receives 2,184-Share Award

What Happened
Catherine T. Chao, a director of Westlake Corp (WLK), was granted 2,184 restricted stock units (RSUs) on August 14, 2026. The award was reported as a derivative acquisition (code A) with no cash paid (reported price $0.00). These RSUs convert into Westlake common stock on a one-for-one basis when they vest, so the award represents an entitlement to 2,184 shares if vesting conditions are met. This is a compensation grant rather than an open-market purchase or sale.

Context
RSU awards are a common form of compensation and retention for directors and executives; they do not represent an immediate purchase or sale of stock and only convert to actual shares if vesting conditions are satisfied. This grant alone should not be interpreted as a direct buying signal by the insider; it is primarily compensation tied to future vesting.
