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, investment banking, and trading fees. Over the last five years, Cullen/Frost Bankers grew its revenue at a decent 11.6% compounded annual growth rate. 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. Cullen/Frost Bankers’s recent performance shows its demand has slowed as its annualized revenue growth of 7.7% over the last two years was below its five-year trend. We’re wary when companies in the sector see decelerations in revenue growth, as it could signal changing consumer tastes aided by low switching costs. Note: Quarters not shown were determined to be outliers because they were impacted by outsized investment gains/losses that are not indicative of the recurring fundamentals of the business.

This quarter, Cullen/Frost Bankers reported year-on-year revenue growth of 9.4%, and its $598.3 million of revenue exceeded Wall Street’s estimates by 1.6%.

Net interest income made up 77.2% of the company’s total revenue during the last five years, meaning lending operations are Cullen/Frost Bankers’s largest source of revenue.

While banks generate revenue from multiple sources, investors view net interest income as the cornerstone - its predictable, recurring characteristics stand in sharp contrast to the volatility of non-interest income.
