Michael Collins, Butterfield's Chairman and Chief Executive Officer, commented, “The first quarter of 2026 was a solid start to the year, with strong financial performance, as well as continuing our M&A driven growth with the acquisition of Rawlinson & Hunter in Guernsey. During the first quarter, we saw sustained demand for our services across banking, wealth management and trust. Net interest income benefited from lower deposit costs, as well as stable deposit volumes in all of our jurisdictions. The reduction in non-interest expenses demonstrates our operational efficiency, particularly during periods of falling interest rates and market volatility.

Company Overview

Founded in 1784 as one of the oldest banks in the Western Hemisphere, Butterfield Bank (NYSE: NTB) provides banking, wealth management, and trust services to individuals and businesses in select offshore financial centers including Bermuda, Cayman Islands, and the Channel Islands.

Sales Growth

Two primary revenue streams drive bank earnings. While net interest income, which is earned by charging higher rates on loans than paid on deposits, forms the foundation, fee-based services across banking, credit, wealth management, and trading operations provide additional income. Unfortunately, Butterfield Bank’s 4.7% annualized revenue growth over the last five years was sluggish. This fell short of our benchmark for the banking sector and is a poor baseline for our analysis.

We at StockStory place the most emphasis on long-term growth, but within financials, a half-decade historical view may miss recent interest rate changes, market returns, and industry trends. Butterfield Bank’s recent performance shows its demand has slowed as its annualized revenue growth of 3.4% 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, impacted by outsized investment gains/losses that are not indicative of the recurring fundamentals of the business.

This quarter, Butterfield Bank reported modest year-on-year revenue growth of 4.5% but beat Wall Street’s estimates by 2.9%.

Net interest income made up 70.8% of the company’s total revenue during the last five years, meaning lending operations are Butterfield Bank’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.

Tangible Book Value Per Share (TBVPS)

Banks operate as balance sheet businesses, with profits generated through borrowing and lending activities. Valuations reflect this reality, emphasizing balance sheet strength and long-term book value compounding ability.

This explains why tangible book value per share (TBVPS) stands as the premier banking metric. TBVPS strips away questionable intangible assets, revealing concrete per-share net worth that investors can trust. On the other hand, EPS is often distorted by mergers and flexible loan loss accounting. TBVPS provides clearer performance insights.

Butterfield Bank’s TBVPS grew at an exceptional 9.3% annual clip over the last five years. TBVPS growth has also accelerated recently, growing by 16.9% annually over the last two years from $19.45 to $26.56 per share.
