Company overview

WESTAMERICA BANCORPORATION

WESTAMERICA BANCORPORATION, trading as WABC and identified in SEC records as CIK 311094, is a regional leader among National Commercial Banks focused on delivering relationship-driven deposit taking, treasury management, commercial lending, and mortgage servicing to middle-market businesses, affluent professionals, and senior executives in the Western U.S. The bank’s core offerings center on low-volatility checking and savings accounts, specialized credit facilities, and advisory services that are tightly coupled with commercial real estate and equipment finance—sectors where the broader North American Finance SIC code emphasizes risk differentiation and capital adequacy. As a publicly listed institution, the company must maintain compliance with evolving capital, liquidity, and consumer-protection regulations while monitoring loan concentration, interest-rate sensitivity, and cyclical commercial real estate exposure that can materially affect performance. Investors and stakeholders should note the most recent periodic disclosure is the Form 10-Q filed in November 1999, which underscores the importance of ongoing diligence, so view live SEC filings on Earnings Feed.
