Idnani Vishal 4

What Happened

• Vishal Idnani, Chief Financial Officer of Western Alliance Bancorporation (WAL), had derivative units converted/exercised resulting in 123 shares reported as acquired at $0.00, and those 123 shares were immediately disposed to the issuer on May 15, 2026, at $74.42 per share for a reported total of $9,154.
• The filing also shows a related derivative conversion record (123 units) reported with N/A pricing in the disposition column; the primary economic effect reported is the $9,154 disposition to the issuer.
• This is a sale/disposition (shares surrendered to the issuer), which is often routine (e.g., to satisfy tax withholding or payment obligations) rather than an outright open-market sale.

Key Details

• Transaction date: May 15, 2026; Filing date: May 19, 2026.

• Footnotes:
  • F1: Units vest and are payable solely in cash: 1/36th on the 15th of each month from March 2026 through February 2029.
  • F2: Each unit is the economic equivalent of one share of Western Alliance common stock.

Context

• The form shows a derivative conversion (M) immediately followed by a disposition to the issuer (D); this pattern is commonly used to satisfy tax withholding or other payment obligations when awards vest or are settled in shares or cash equivalents. It does not necessarily signal a personal liquidity-driven open-market sale.
• For retail investors, purchases are generally more informative about insider sentiment than routine surrenders to the issuer; this filing reports a conversion and surrender rather than a buy.
