As we predicted, our net interest margin continues to increase as our assets reprice higher. We expect this trend to continue over the next several years," said David Zalman, Prosperity's Senior Chairman and Chief Executive Officer.

Prosperity has been ranked as one of Forbes Best Banks since the list's inception in 2010 and was ranked in the top 10 for 14 consecutive years.

Prosperity maintained a high tangible equity to tangible assets ratio of 11.2%, with tangible equity of $3.952 billion," continued Zalman.

We will continue to be opportunistic, work hard, stay close to our customers and their needs and maintain a quality loan portfolio," continued Zalman.

"I would like to thank our customers for their business and continued trust and our associates, directors and officers for their hard work and dedication," concluded Zalman.

Net income per diluted common share was $1.37 for the three months ended March 31, 2025 compared with $1.18 for the same period in 2024, an increase of 16.1%.

Noninterest income was $41.3 million for the three months ended March 31, 2025 compared with $38.9 million for the same period in 2024, an increase of $2.4 million or 6.3%.

Noninterest expense was $140.3 million for the three months ended March 31, 2025 compared with $135.8 million for the same period in 2024, an increase of $4.5 million or 3.3%, primarily due to an increase in salaries and benefits related to the merger of Lone Star State Bancshares, Inc.

Further, Prosperity believes that these non-GAAP financial measures provide useful information by excluding certain items that may not be indicative of its core operating earnings and business outlook.

Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies' non-GAAP financial measures having the same or similar names. Please refer to the "Notes to Selected Financial Data" at the end of this Earnings Release for a reconciliation of these non-GAAP financial measures to the nearest respective GAAP financial measures.
