Insights

Corporate Governance Analyst

Director executed small purchases totaling 54 shares via DRIP/OCP on 10/08/2025.

The transactions are coded P indicating purchases and were executed at prices of $27.4849 and $27.4207, consistent with routine share-acquisition activity such as a dividend reinvestment plan or officer/employee purchase program. The filing shows 300 shares held indirectly by a spouse, which is disclosed to clarify beneficial ownership.

The scale is modest relative to typical market-moving insider trades, so near-term market impact is likely limited; investors can note the director-level purchase as a routine insider accumulation on 10/08/2025.
