San Antonio’s banking scene just got a shakeup, as Brent Given, interim chairman, president and CEO of San Antonio-based Texas Partners Bank, steps into a new role as Prosperity Bank’s San Antonio-area chairman. His move comes on the heels of Texas Partners officially becoming part of Prosperity on Feb. 1, 2026, a deal that folds an 11-branch community lender into the Houston-based regional bank and broadens Prosperity’s reach across Central Texas. Bank officials say customers should not see any immediate changes to their accounts until systems are converted later this year.
Merger closed and leadership moves
In a press release from Prosperity Bancshares, the company said it had completed the merger and confirmed that Given and other Texas Partners executives will take on senior roles at Prosperity Bank. The Federal Reserve signed off on the holding-company application in early January, clearing a key regulatory hurdle, according to the Federal Reserve Board. SEC filings and the related registration statement report that Southwest Bancshares, the parent of Texas Partners, had roughly $2.4 to $2.5 billion in assets and operated 11 banking centers across San Antonio, Austin and the Hill Country, as detailed in the registration statement.
What customers will see
For customers, the message is essentially to sit tight for now. Texas Partners’ customer FAQ says there are no immediate changes to accounts, debit cards or online banking, and that customers can use Prosperity ATMs without surcharges starting Feb. 1, according to Texas Partners Bank. The operational conversion of systems and accounts is scheduled for November 2026, at which point Texas Partners branches will be rebranded as Prosperity locations. Until then, the bank is urging customers to keep their contact information up to date and says more specifics will roll out as the conversion date approaches.
Local impact and the price tag
Local coverage put the purchase price at roughly $269 million based on Prosperity’s share price at the time and highlighted Texas Partners’ roughly $2.4 billion in assets, characterizing the deal as an all-stock combination, according to the San Antonio Express-News. Prosperity issued about 4.1 million shares to Southwest’s shareholders as part of the consideration, a structure designed to add scale and deposits rather than hand out a big cash payday. For San Antonio, the transaction trims the list of locally headquartered banks while giving former Texas Partners customers access to a much larger branch and ATM network.
Why Prosperity is on the hunt
Prosperity’s investor materials show the bank has been busy this winter, completing the American Bank transaction in early January and announcing a Stellar Bancorp agreement later in January, moves the company says build deposits and branch coverage across Texas and Oklahoma. Management has framed the acquisitions as a way to grow core deposits and operating scale while still keeping lending and relationship decisions in the hands of local market teams. For community bankers and customers in San Antonio, the effect is more tangible, fewer independent hometown banks and a bigger regional player handling the local accounts.
