PB’s Acquisition Strategy Remains a Key Revenue Growth Driver
Acquisitions remain central to Prosperity Bancshares’ expansion strategy. Since its inception, the company has grown significantly by acquiring community banks and select branches from other institutions, completing 48 acquisitions.
This year, PB completed its American Bank Holding Corporation acquisition in January, Southwest Bancshares in February and Stellar Bancorp on July 1. These deals expand its balance sheet, lending relationships and banking franchise.
PB completed the American Bank integration in September 2026, with Texas Partners Bank and Stellar Bank integrations scheduled for November 2026 and March 2027, respectively. Prosperity Bancshares has already begun realizing cost savings from American Bank and Texas Partners, with another $20-$25 million in pre-tax savings likely to be realized this year. Management expects full cost-saving benefits from American Bank and Texas Partners in 2027, while Stellar is expected to generate $80-$85 million in savings. Thus, total remaining pre-tax savings from these deals are estimated at $100-$110 million.
PB’s Revenues Benefit From a Favorable Deposit Mix & NIM
Apart from steady benefits from its acquisition-related scale, Prosperity Bancshares’ favorable deposit mix and expanding NIM support its top-line growth. As of June 30, 2026, non-interest-bearing deposits accounted for 32.9% of total deposits, helping contain funding costs and support net interest income (NII) and NIM.
As of June 30, 2026, fixed-rate loans accounted for 37.6% of the loan portfolio, with the remainder comprising floating- and variable-rate loans. So, asset repricing, higher rates and steady loan demand are expected to drive NIM and NII expansion.
Net Interest Margin Trend

The company expects loan balances to be flat for the remainder of 2026. Though the Stellar deal will add about $200 million of loans in the second half of 2026, elevated paydowns and aggressive competitor pricing will likely limit overall growth. Management expects exit NIM of 3.70%-3.75% in 2026 and 3.80%-3.85% in 2027. We project NII to witness a CAGR of 19.5% through 2028 and NIM of 3.58% in 2026, 3.82% in 2027 and 3.89% in 2028.
PB’s Fee Income Complements NII
PB is focused on diversifying its revenue mix by expanding card-related income, deposit account service charges and other revenue sources. In the first half of 2026, credit, debit and ATM card income, service charges on deposit accounts and other income increased 7%, 19% and 16.9%, respectively, year over year.
We expect card-related income, service charges on deposit accounts and other income to witness a CAGR of 16.2%, 18.5% and 23.6%, respectively, through 2028.
Parting Thoughts on PB’s Revenue Drivers
Prosperity Bancshares is positioned to grow revenues through acquisition-led expansion, improving NIM, a favorable deposit mix and rising fee income. The integration of American Bank, Texas Partners Bank and Stellar Bancorp is expected to expand operating scale and generate meaningful cost savings. However, competitive loan pricing, rising mortgage rates, real estate concentration and integration costs remain key risks to sustained revenue growth.
We expect total revenues to grow at the rate of 40.1%, 16% and 4.7% in 2026, 2027 and 2028, respectively.
PB’s Peers & Their Revenue Drivers
Bank OZK (OZK - Free Report) revenue growth will likely be supported by commercial and industrial (CIB) loan expansion, new branch openings and higher fee income from trust, wealth management and treasury services. OZK expects mid- to high-single-digit revenue growth in 2026, with further gains in 2027 and beyond. We project net revenues to witness a CAGR of 4.7% through 2028, driven by growth in NII and non-interest income.
Texas Capital Bancshares (TCBI - Free Report) revenue growth will likely be supported by strategic diversification, commercial and industrial loan expansion and increased contributions from investment banking and other fee-based businesses. Texas Capital’s management expects adjusted total revenues to grow at a mid-to-high single-digit rate in 2026, with non-interest revenues projected at $270-$290 million. Continued investments in technology, corporate banking and new business offerings are expected to support sustainable revenue growth and improve operating leverage.
