Insights

Financial Analyst

TL;DR: Director sold 7,383 FFBC shares at $26.54 on 08/22/2025; remaining holdings are modest and mostly indirect.

The transaction is a standard disclosure of insider trading activity and does not by itself indicate company-level operational changes. The sale size (7,383 shares) should be compared to total insider holdings and recent trading patterns to assess significance. Reported post-transaction holdings are 46,480 shares indirectly and 2,957 shares directly, which frames the director's ongoing economic interest.

Corporate Governance Expert

TL;DR: Routine Form 4 filing for a director-initiated sale, filed under POA; disclosure meets Section 16 requirements.

Execution by a power of attorney (Maria Hinkel) is noted and dated 08/25/2025, which is consistent with administrative filing practices.
