Western Alliance (WAL) Vice Chair Dale Gibbons Sells 726 Shares

What Happened

Dale Gibbons, Vice Chair and Chief Banking Officer, Deposits at Western Alliance (WAL), had three cash‑settled stock unit awards vest and be converted on July 15, 2026. A total of 726 units (285 + 212 + 229) were recorded as acquired at $0 (vesting) and immediately disposed to the issuer at $81.79 per share, generating total proceeds of $59,379.
These transactions are recorded as exercise/conversion of derivatives (code M) followed by disposition to the issuer (code D). This appears to be routine cash settlement of vested units rather than an open‑market sale.

Context

These were cash‑settled unit vestings (not open‑market purchases or sales of previously held shares). The units were converted/settled and immediately surrendered to the issuer—commonly done to cover tax withholding or to receive cash value—so this action does not necessarily signal a change in insider sentiment.
Transaction codes: M = exercise/conversion of a derivative ( unit conversion ), D = disposition to issuer.
