[Form 4] Columbia Financial, Inc. Insider Trading Activity

Rhea-AI Filing Summary

Columbia Financial (CLBK) – Form 4 insider activity

EVP & Chief HR Officer Jenifer White reported one transaction dated 25 Jul 2025. Through the Columbia Bank Stock-Based Deferral Plan, the executive acquired 37.8599 phantom stock units at $14.07, an indirect, cash-less purchase that will settle in common shares when distributed. The new units lift her balance in the plan to 2,668.0686 shares.

Following the filing, White’s ownership comprises:

• 3,352 shares held directly
• ≈26k shares held indirectly through ESOP, SERP, SIM and four time-/performance-vested stock-award tranches
• 28,147 employee stock options exercisable at $15.94–$20.54, expiring 2032-2035

The reported purchase is valued at ~$0.5k and does not represent an open-market buy. The filing is routine and does not materially alter insider ownership or signal a significant change in sentiment.

Insights

Securities Analyst

TL;DR: Small, plan-based share accrual; impact immaterial, signals status-quo.

The acquisition is only 38 phantom shares worth roughly $535 and was executed automatically under the deferred compensation plan, not via discretionary open-market purchase. Ownership after the event—about 29k shares/units plus 28k options—remains unchanged in strategic terms. No sales were reported, so there is no negative read-through, but the miniscule size means little incremental alignment with shareholders. Overall, a standard administrative update with no valuation impact.
