Sales Growth
From lending activities to service fees, most banks build their revenue model around two income sources. Interest rate spreads between loans and deposits create the first stream, with the second coming from charges on everything from basic bank accounts to complex investment banking transactions. Regrettably, Byline Bancorp’s revenue grew at a mediocre 9% compounded annual growth rate over the last five years. This was below our standard 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. Byline Bancorp’s recent performance shows its demand has slowed as its annualized revenue growth of 6.8% 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, Byline Bancorp reported year-on-year revenue growth of 6.6%, and its $117.7 million of revenue exceeded Wall Street’s estimates by 1.8%.
Net interest income made up 84.2% of the company’s total revenue during the last five years, meaning Byline Bancorp 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.

Tangible Book Value Per Share (TBVPS)
Banks profit by intermediating between depositors and borrowers, making them fundamentally balance sheet-driven enterprises. Market participants emphasize balance sheet quality and sustained book value growth when evaluating these institutions.
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.
Byline Bancorp’s TBVPS grew at an impressive 7.9% annual clip over the last five years. TBVPS growth has also accelerated recently, growing by 14% annually over the last two years from $18.84 to $24.48 per share.
Over the next 12 months, Consensus estimates call for Byline Bancorp’s TBVPS to grow by 11.4% to $27.28, mediocre growth rate.
