Company Overview
Founded in 1884 and serving communities from Mendocino County in the north to Kern County in the south, Westamerica Bancorporation (NASDAQ: WABC) provides banking services to individuals and small businesses throughout Northern and Central California.
Sales Growth
In general, banks make money from two primary sources. The first is net interest income, which is interest earned on loans, mortgages, and investments in securities minus interest paid out on deposits. The second source is non-interest income, which can come from bank account, credit card, wealth management, investing banking, and trading fees. Thankfully, Westamerica Bancorporation’s 5.3% annualized revenue growth over the last five years was decent. Its growth was slightly above the average banking company and shows its offerings resonate with customers.

Long-term growth is the most important, but within financials, a half-decade historical view may miss recent interest rate changes and market returns. Westamerica Bancorporation’s recent performance marks a sharp pivot from its five-year trend as its revenue has shown annualized declines of 9.4% over the last two years. Note: Quarters not shown were determined to be outliers, impacted by outsized investment gains/losses that are not indicative of the recurring fundamentals of the business.
This quarter, Westamerica Bancorporation’s revenue fell by 13.6% year on year to $64 million but beat Wall Street’s estimates by 2.4%.
Net interest income made up 83.3% of the company’s total revenue during the last five years, meaning Westamerica Bancorporation barely relies on non-interest income to drive its overall growth.

Our experience and research show the market cares primarily about a bank’s net interest income growth as non-interest income is considered a lower-quality and non-recurring revenue source.
