Old Second Bancorp, Inc. reported that director John Ladowicz resigned from its Board of Directors effective September 14, 2025.

Ladowicz had served on the Board since 2008 and was a member of the Audit, Compensation, Nominating and Corporate Governance, Loan, and Risk and Insurance committees. The company does not plan to immediately fill the vacancy and will instead reduce the Board size by one. Earlier in February 2025, the Board realigned its Class I, II and III directors to keep the classes as nearly equal in number as possible, anticipating retirements including Ladowicz’s.
