Company overview
Born from the ashes of a failed Florida thrift during the 2009 financial crisis, BankUnited (NYSE: BKU) is a regional bank that provides commercial lending, deposit services, and treasury solutions to businesses and consumers primarily in Florida and the New York metropolitan area.
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, BankUnited’s 4.5% annualized revenue growth over the last five years was sluggish. This fell short of our benchmark for the banking sector and is a rough starting point for our analysis.
Long-term growth is the most important, but within financials, a half-decade historical view may miss recent interest rate changes and market returns. BankUnited’s annualized revenue growth of 6.3% over the last two years is above its five-year trend, which is encouraging. 
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, BankUnited’s $280.4 million of revenue was flat year on year, falling short of Wall Street’s estimates.
Net interest income made up 89.2% of the company’s total revenue during the last five years, meaning BankUnited barely relies on non-interest income to drive its overall growth.
Markets consistently prioritize net interest income growth over fee-based revenue, recognizing its superior quality and recurring nature compared to the more unpredictable non-interest income streams.

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. Traditional metrics like EPS are helpful but face distortion from M&A activity and loan loss accounting rules.
BankUnited’s TBVPS grew at a tepid 3.1% annual clip over the last five years. The last two years show a similar trajectory as TBVPS grew by 3.5% annually from $36.52 to $39.10 per share.
Over the next 12 months, Consensus estimates call for BankUnited’s TBVPS to grow by 12.1% to $43.84, mediocre growth rate.
