Hugh H. McLean has amended his previous filing related to stock transactions involving Old Second Bancorp, Inc. This amendment, filed on October 20, 2026, provides important clarifications regarding his ownership of restricted stock units and common stock.

McLean is a director at Old Second Bancorp, a company that operates within the state commercial banks sector. The filing indicates that he acquired 3,077 shares of common stock through the settlement of restricted stock units on February 21, 2026. Following this transaction, he now owns a total of 160,351 shares of the bank’s common stock.

The amendment corrects an earlier filing that inaccurately reported the transaction. According to the filing, "This amendment corrects the original Form 4, which incorrectly reported the settlement using transaction code F." The filing emphasizes the necessity for accurate reporting in corporate governance, particularly in the banking sector.

Old Second Bancorp, Inc., which operates under the ticker symbol OSBC, is incorporated in Delaware and is headquartered in Aurora, Illinois. The company is known for its services in the state commercial banking industry, which may face increased scrutiny as transparency in executive compensation becomes more critical.

This amendment may have implications for other directors and executives within the banking sector, as it highlights the importance of accurate filings and the potential consequences of misreporting. The filing does not specify what actions, if any, will follow this amendment.
