1. Credit Risk

As a bank holding company, Byline Bancorp's primary business involves lending to small and medium-sized businesses, commercial real estate, and lower middle market companies. This exposes the company to significant credit risk, which is the risk that borrowers will default on their loan obligations. An increase in loan defaults could lead to higher loan loss provisions, reduced interest income, and an erosion of capital, directly impacting the company's financial performance and stability.

2. Interest Rate Risk

Byline Bancorp's profitability is highly sensitive to changes in interest rates. The company generates revenue from the spread between the interest earned on its loans and investments and the interest paid on its deposits and borrowings. Fluctuations in interest rates can compress this net interest margin. For instance, a rapid increase in funding costs (e.g., higher deposit rates) without a corresponding increase in asset yields, or vice versa, could negatively impact the company's profitability.

3. Geographic Concentration Risk

Byline Bancorp operates primarily within a concentrated geographic area, with 43 of its 44 branches located in the Chicago metropolitan area and one in Brookfield, Wisconsin. This significant geographic concentration makes the company highly susceptible to local economic conditions. An economic downturn, adverse business conditions, or significant industry-specific challenges within the Chicago metropolitan area could disproportionately affect the credit quality of its loan portfolio, reduce demand for its banking products and services, and ultimately impact its financial performance more severely than if its operations were more geographically diversified.

Byline Bancorp (symbol: BY) operates in several addressable markets primarily within the United States, with a concentration in the Chicago metropolitan area and parts of Illinois and Wisconsin. Here's an overview of the estimated market sizes for its main products and services:

Here are 3-5 expected drivers of future revenue growth for Byline Bancorp (BY) over the next 2-3 years:

1. Loan Portfolio Growth: Byline Bancorp anticipates continued growth in its loan and lease portfolio, with management expecting mid-single-digit loan growth for 2026, primarily within its commercial banking segment. This expansion, particularly in commercial and industrial loans, owner-occupied commercial real estate, and government-guaranteed loans like SBA 7(a) and USDA loans, is a fundamental driver of net interest income and overall revenue.
2. Expansion of Commercial Payments Business: The company launched a new commercial payments business in early 2025, which has shown promising early success. This initiative is expected to scale significantly in 2026, targeting high-volume ACH transactions and payroll processors, thereby enhancing service offerings, increasing the customer base, and contributing to fee income streams.
3. Net Interest Margin (NIM) Management and Expansion: Byline Bancorp has demonstrated effective management of its net interest margin, which expanded in 2025, reaching 4.36% in the fourth quarter. The bank's ability to optimize its loan portfolio repricing mix and manage deposit costs is crucial for maintaining and growing net interest income, a key component of revenue, in varying interest rate environments.
4. Strategic Acquisitions and Integration: Byline Bancorp has a history of strategic acquisitions, such as the successful integration of First Security Bancorp in 2025. These acquisitions contribute to growth by expanding the company's branch network, enhancing its capabilities and service offerings, and increasing its customer base within its operational regions. The company's capital allocation priorities include mergers and acquisitions.
5. Growth in Non-Interest Income: Beyond its commercial payments business, Byline Bancorp aims to increase other sources of non-interest income. This includes income from wealth management and trust services, fees and service charges on deposits, and gains on sales of U.S. government-guaranteed loans. Diversifying revenue streams through these non-interest income sources provides additional growth opportunities and financial stability.
