Actionable Insight • Neutral

Monitor the Stellar shareholder vote on May 27 and the expected close on July 1. Prosperity's GAAP earnings decline warrants attention, but the deal's regulatory path is cleared. Post-merger integration and combined financial performance will be key catalysts for both stocks.
