Under the terms of the agreement, Prosperity issued 0.3803 shares of its common stock and provided $11.36 in cash for each outstanding share of Stellar common stock. While the legal merger is effective immediately, Stellar banking locations will continue operating under their current name until full operational integration is finalized in March 2027. At that time, customers will gain access to the full range of services offered across Prosperity Bank’s extensive footprint.
