Byline Bancorp, Inc. has announced significant leadership changes that will take effect on January 1, 2027. The changes include the retirement of two key executives and the appointment of their successors, marking a pivotal moment for the company as it navigates the competitive landscape of the state commercial banking sector.

Brogan M. Ptacin, the Executive Vice President and Head of Commercial Banking, has decided to retire effective December 31, 2026. Following his retirement, he will continue to work with Byline Bank in a non-executive, part-time advisory capacity. This transition signifies a shift in leadership as the company prepares for future challenges and opportunities.

In a move to fill the gap left by Ptacin, Sean H. McGuire has been appointed as the new Chief Commercial Banking Officer. McGuire, who joined Byline Bank in July 2019, previously served as the Commercial Group President at MB Financial Bank. His extensive experience in banking and leadership positions is expected to bring fresh insights to the role.

Additionally, Mark Fucinato, the Executive Vice President and Chief Credit Officer, is also set to retire on December 31, 2026. He will similarly remain with the bank in an advisory role. Scott Hawthorne, currently serving as Deputy Chief Credit Officer, will take over as Chief Credit Officer, effective January 1, 2027. Hawthorne's background includes senior credit roles at Fifth Third Bank and MB Financial Bank, positioning him well for his new responsibilities.

These leadership changes come at a critical time for Byline Bancorp, as the company seeks to enhance its competitive edge in the market. The state commercial banking sector is evolving, and the new appointments are likely to influence the bank's strategic direction moving forward.

The filing does not specify what happens next, but the leadership transitions are expected to be closely monitored by industry observers and competitors alike.
