Bank of N.T. Butterfield & Son

Simply Wall St Value Rating: ★★★★☆☆

Overview: The Bank of N.T. Butterfield & Son Limited offers community, commercial, and private banking services to individuals and small to medium-sized businesses, with a market capitalization of approximately $1.53 billion.

Operations: The primary revenue stream for NTB comes from its banking segment, which generated $579.93 million.

Bank of N.T. Butterfield & Son, with assets totaling US$14.2 billion and equity at US$1 billion, is navigating a challenging environment with earnings growth at -4.1% over the past year compared to the industry average of -1.2%. Despite this, it trades at 77.2% below its estimated fair value and has low-risk funding as 96% of liabilities are customer deposits. With total deposits reaching US$12.7 billion and loans at US$4.5 billion, the bank's net interest margin stands at 2.6%. However, a high level of bad loans (3.3%) and a low allowance for these loans (17%) present concerns amid strategic expansions in retail banking sectors like the Channel Islands and Singapore aimed to boost market share further supported by recent share repurchases worth $69 million representing 4% of outstanding shares which could enhance shareholder value if rising costs don't offset potential gains from these initiatives.
