CEO/President Commentary

Roberto R. Herencia, Executive Chairman and CEO of Byline Bancorp, commented, "We delivered record earnings and returned more than $20 million of capital to stockholders through share repurchases and a 16.7% increase in our common dividend to $0.14 per share during the third quarter. We also continued to advance our strategic priorities with the recently announced acquisition of Illinois State Bancorp, Inc., parent of First Nations Bank and The Bank of Bourbonnais. The transaction expands our market presence, strengthens our core deposit base, and adds talented bankers and long-standing customer relationships."

Alberto J. Paracchini, President of Byline Bancorp, added, "The third quarter produced record net interest income of $103.7 million and expanded our net interest margin by five basis points to 4.33% in a quarter when funding costs rose across the industry. Pre-tax, pre-provision return on average assets was 2.45%. Deposits grew at an 8.5% annualized rate while our cost of deposits rose three basis points. We believe our strong capital position provides the flexibility to support growth, capitalize on market opportunities, and create long-term value as we pursue our vision of becoming the preeminent commercial bank in Chicago."

Net Interest Income

Net interest income for the third quarter of 2026 was $103.7 million, an increase of $2.8 million, or 2.8%, from the second quarter of 2026. The increase in net interest income was primarily attributable to higher interest income from investment securities, lower interest expense on other borrowings resulting from reduced wholesale funding levels, and the additional day in the quarter, partially offset by higher interest ex

Net Interest Income

Net interest income for the second quarter of 2026 was $100.8 million, an increase of $973,000, or 1.0%, from the first quarter of 2026. The increase in net interest income was primarily due to one additional calendar day, partially offset by higher interest expense related to increased funding costs.

Tax-equivalent net interest margin(1) for the second quarter of 2026 was 4.29%, a decrease of five basis points compared to the first quarter of 2026. The decrease primarily reflected modest compression in earning asset yields and
