HOUSTON
, Oct. 29, 2025 /PRNewswire/ — Prosperity Bancshares, Inc.® (NYSE: PB) (“Prosperity Bancshares”), the parent company of Prosperity Bank® (collectively, “Prosperity”), reported net income of $137.6 million for the quarter ended September 30, 2025, compared with $127.3 million for the same period in 2024. Net income per diluted common share was $1.45 for the quarter ended September 30, 2025, compared with $1.34 for the same period in 2024. The annualized return on third quarter average assets was 1.44%. Additionally, deposits increased $308.7 million during the third quarter of 2025. Nonperforming assets remain low at 0.36% of third quarter average interest-earning assets.

“In the third quarter we signed a definitive merger agreement with Southwest Bancshares, Inc., the parent company of Texas Partners Bank headquartered in San Antonio, Texas.  We are excited about this transaction as it significantly expands our San Antonio metro footprint with 4 additional branches and increased deposit market share, bolsters our presence in the Texas Hill Country and adds an experienced C&I lending team,” said David Zalman, Prosperity’s Senior Chairman and Chief Executive Officer.

“I would also be remiss not to mention how excited we are about our pending merger with American Bank Holding Corporation in Corpus Christi, Texas. The combination will strengthen our presence and operations in South Texas and surrounding areas and enhance our presence in Central Texas, including San Antonio,” continued Zalman.

“I am also pleased to announce that the Board of Directors approved increasing the fourth quarter 2025 dividend to $0.60 per share from $0.58 per share that was paid in the prior four quarters. The increase reflects the continued confidence the Board has in our company and our markets. The compound annual growth rate in dividends declared from 2003 to 2025 was 10.7%. We continue to share our success with our shareholders through the payment of dividends and opportunistic stock repurchases, while also continuing to grow our capital,” stated Zalman.

“As of October 2025, Texas boasts one of the world’s strongest and most diverse economies, ranking as the 8th largest globally with a GDP of approximately $2.77 trillion in 2024. The state produces about 9.3% of U.S. GDP and continues to outpace national growth in many metrics. Although the economy is showing some signs of moderation, influenced by factors such as tariffs and immigration policies, we believe Texas remains the best state for business with a pro-business attitude and no state income tax. This is evidenced by major corporations continuing to move their operations to Texas and Oklahoma,” added Zalman.

“As of October 2025, Oklahoma’s economy is demonstrating resilience and modest growth, outpacing national averages in key areas such as unemployment and population expansion despite broader U.S. slowdowns from tariffs and policy uncertainties,” continued Zalman.

“I would like to thank our customers, associates, directors and shareholders for their hard work and loyalty.  Our fundamentals and resolve have never been stronger to continue to build this successful company,” concluded Zalman.

Notes to Selected Financial Data (Unaudited)
(Dollars and share amounts in thousands, except per share data)

NOTES TO SELECTED FINANCIAL DATA

Prosperity’s management uses certain non-GAAP (generally accepted accounting principles) financial measures to evaluate its performance. Specifically, for internal planning and forecasting purposes, Prosperity reviews each of diluted earnings per share, return on average assets, return on average common equity, and return on average tangible common equity, in each case excluding merger related provision for credit losses, net of tax, merger related expenses, net of tax, FDIC special assessment, net of tax, and net gain on sale or write-up of securities, net of tax; return on average tangible common equity; tangible book value per share; the tangible equity to tangible assets ratio; allowance for credit losses to total loans excluding Warehouse Purchase Program loans; the efficiency ratio, excluding net gains and losses on the sale, write-down or write-up of assets and securities; and the efficiency ratio, excluding net gains and losses on the sale, write-down or write-up of assets and securities, merger related expenses and FDIC special assessment. In addition, due to the application of purchase accounting, Prosperity uses certain non-GAAP financial measures and ratios that exclude the impact of these items to evaluate its allowance for credit losses to total loans (excluding Warehouse Purchase Program loans). Prosperity has included information below relating to these non-GAAP financial measures for the applicable periods presented.
