Actionable Insight ◆ Mixed

Monitor the pending merger with Northfield Bancorp and second-step conversion offering, which could significantly impact capital structure and growth trajectory. The decline in net income from Q4 2025 despite margin expansion suggests temporary headwinds from merger costs that may reverse post-integration.
