Summary

Byline Bancorp announced a definitive agreement to acquire Illinois State Bancorp in a cash-and-stock deal valued at approximately $87.9 million, based on Byline's October 5 closing price. The transaction adds $617 million in assets, $470 million in loans, and $510 million in deposits, expanding Byline's Chicago footprint to 48 branches and roughly $10.5 billion in total assets. Byline will issue about 1.4 million shares and pay $28.9 million in cash, plus $5.1 million for option settlements. The deal is expected to close in Q1 2027, pending regulatory and Illinois State Bancorp shareholder approvals. This is a meaningful but digestible acquisition for Byline, which has a market cap near $1.7 billion, and it reinforces the company's stated goal of becoming the preeminent commercial bank in Chicago.
