Strategic, Accretive M&A Expands Texas Footprint
Completed American Bank merger (effective 01/01/2026), expect Southwest / Texas Partners merger effective 02/01/2026, and announced acquisition of Stellar Bancorp. Stellar deal moves combined Houston deposit rank from #9 to #5 and makes Prosperity the largest Texas-based bank in that market and second-largest by deposits in the state. Management describes Stellar as credit-disciplined with an attractive noninterest-bearing deposit mix and expects purchase-accounting accretion (~$30M in 2027) and meaningful franchise/earnings accretion.
