Prosperity Bancshares, Inc. Completes Merger with Southwest Bancshares

In a significant move within the financial sector, Prosperity Bancshares, Inc. (NYSE: PB), the parent company of Prosperity Bank, announced the successful completion of its merger with Southwest Bancshares, Inc. This strategic merger, finalized on February 1, 2026, marks a pivotal moment for both entities, aiming to enhance banking services and expand their footprint in Texas.

Details of the Merger

Under the agreed terms, Prosperity Bancshares has issued approximately 4,095,397 shares of its common stock to the former shareholders and award recipients of Southwest. This merger not only consolidates resources but also aims to improve customer service by integrating the strengths of both organizations.

Brent Given, who held the position of Interim Chairman, President, and CEO of Texas Partners Bank—a wholly owned subsidiary of Southwest located in San Antonio—will assume the role of San Antonio Area Chairman at Prosperity Bank. Tom Moreno, previously the Chief Operating Officer at Texas Partners, will also join Prosperity in a senior management position. Furthermore, members of the Texas Partners management team will retain crucial leadership roles to ensure continuity and retain the relationships built in the local communities.

Until the completion of operational integration, which is scheduled to be finalized by November 2026, these branches will continue to operate under the Texas Partners Bank name. This extension allows existing customers to maintain familiarity while transitioning to Prosperity Bank services. After integration, customers will have access to Prosperity Bank's extensive suite of full-service banking options, significantly enhancing their banking experience.
