Insights

Corporate Governance Expert

TL;DR: Insider holdings in PPBI were fully disposed at merger close; transactions reflect conversion mechanics, not open-market sales.

The Form 4 documents that Edward Wilcox, President & COO, disposed of both direct and indirect PPBI common stock on 08/31/2025 as part of the Merger Agreement with Columbia Banking System, Inc. The filing reports 161,076 shares disposed directly and 125,430 shares disposed indirectly via a trust, with no PPBI shares remaining post-transaction. The explanation explicitly ties the disposals to the conversion of PPBI shares into 0.9150 Columbia shares per PPBI share, and notes cash for fractional shares. This is a routine post-merger conversion disclosure and does not indicate opportunistic insider selling outside the merger terms.
