Cash Settled Restricted Stock Units financial

"security_title: Cash Settled Restricted Stock Units"

Cash-settled restricted stock units are employee compensation promises that mirror the value of company shares but pay out in cash instead of delivering actual stock once the units vest. Think of them as a future paycheck tied to the company’s share price that is paid after time or performance conditions are met. Investors watch them because they create future cash obligations for the company and avoid share dilution, both of which can affect earnings, cash flow and per-share metrics.

Disposition to issuer financial

"transaction_code_description: Disposition to issuer"

economic equivalent financial

"Each unit is the economic equivalent of one share of Western Alliance Bancorporation common stock."

401K Plan financial

"Reflects shares held in the 401K Plan to include employer match as of 5/14/2026."

A 401(k) plan is an employer-sponsored retirement savings account that lets workers set aside part of their paycheck into investments, often with tax breaks and sometimes with matching contributions from the employer. Think of it as a workplace piggy bank that grows through employee contributions, optional company top-ups, and market returns; it matters to investors because it shapes household retirement security, drives large flows of money into public markets, and affects a company’s compensation costs and ability to attract and keep talent.
