With the latest numbers on the table, the next step is to see how this earnings profile lines up with the key narratives around Byline Bancorp, and where the hard data supports or challenges what the market has been saying.

33% net margin sets the tone

• On a trailing basis, Byline generated net income of US$139.4 million on revenue of US$422.9 million, which works out to a 33% net profit margin compared to 31.3% a year earlier.
• Consensus narrative points to operational efficiency gains from integrations and digital upgrades, and that aligns with the margin profile, but:
  • Trailing one year earnings growth of 17.6% is ahead of the 12.5% per year five year average, which is consistent with the idea that recent efficiency work is feeding through to the bottom line.
  • At the same time, analysts expect earnings growth of 1.9% per year going forward, so the current 33% margin sits against a much slower growth outlook than the recent history suggests.

Stronger profitability and a slower growth outlook sitting side by side is exactly what the consensus narrative is trying to weigh up for this bank.

Loan book above US$7.5b

• Total loans were US$7.6b at Q4 2025 on a reported basis, with non performing loans of US$71.3 million compared to US$63.2 million in Q3 2025 and US$53.6 million in Q1 2025.
• Skeptics in the bearish narrative focus on credit quality and regional concentration, and the loan data gives some concrete context to that concern:
  • Non performing loans moved between US$53.6 million and US$71.3 million over the last five reported quarters, which is what critics have in mind when they talk about worsening credit trends and higher credit costs risk.
  • The concentration in Chicago and Midwest markets mentioned by bears means this US$7.6b loan book is tied to a specific region, so shifts in those local economies can matter more than broad US averages.

Pessimistic investors often anchor on those non performing loan figures when they outline the cautious view on credit risk for this name. 🐻 Byline Bancorp Bear Case

P/E of 10.8x versus peers

• With the share price at US$33.03, Byline trades on a P/E of 10.8x versus 11.7x for the wider US banks group and 14.9x for peers, while the DCF fair value is given as US$63.20.
• Bullish arguments lean on that valuation gap and past profit growth, and the numbers here provide some clear talking points:
  • Trailing twelve month EPS sits at US$3.09 and has grown at 12.5% per year over five years, so the current 10.8x multiple and the DCF fair value of US$63.20 together frame a wide gap between price and the provided model value.
  • Even using the single allowed analyst price target of US$36.20, the current US$33.03 price sits below that level, which bullish investors may view as some room for upside if the company maintains similar profitability.

Supporters of the optimistic view often point to this mix of multi year earnings growth and a discount to both peers and DCF fair value when they discuss the upside case. 🐂 Byline Bancorp Bull Case
