Additionally, loans increased $219.8 million during the second quarter of 2025. Nonperforming assets remain low at 0.33% of second quarter average interest-earning assets.

"I am excited to share that our bank continues to grow, with double digit increases in net income and earnings per share compared with the second quarter of 2024. Our net interest margin also improved to 3.28%, a 24 basis point increase compared with the second quarter of 2024 as our interest-bearing assets continue to reprice. Loans grew $219.8 million during the second quarter of 2025, and we continue to see cautious enthusiasm from our customers. As mentioned in my previous comments, these are the results we expected, and these tailwinds should continue to be positive over the next 12 and 24 months," said David Zalman, Prosperity's Senior Chairman and Chief Executive Officer.

"I am proud to announce that we entered into a definitive agreement with American Bank Holding Company in Corpus Christi to merge. We have followed American Bank closely for more than two decades and have tremendous respect for the bank and for the people that have contributed to its success. Our banks have a complementary footprint, and we are familiar with and remain committed to the communities that American Bank serves, including with both financial products and community support. This combination will strengthen our presence and operations in South Texas and surrounding areas and enhances our presence in Central Texas, including in San Antonio, a highly desirable, high growth area," stated Zalman.

"Texas and Oklahoma continue to shine as more people and companies move to the states because of the business-friendly political structure and no state income tax. Texas was recently rated as the second-best state for business in 2025 by CNBC," continued Zalman.

"Thank you to our customers, shareholders and associates that make all of this possible," concluded Zalman.

Results of Operations for the Three Months Ended June 30, 2025

Net income was $135.2 million(2) for the three months ended June 30, 2025 compared with $111.6 million(3) for the same period in 2024, an increase of $23.6 million or 21.1%. Net income per diluted common share was $1.42 for the three months ended June 30, 2025 compared with $1.17 for the same period in 2024, an increase of 21.4%. The changes were primarily due to an increase in net interest income, a decrease in merger related provision and expenses and lower regulatory assessments and FDIC insurance, partially offset by a decrease in net gain on sale or write-up of securities. On a linked quarter basis, net income was $135.2 million(2) for the three months ended June 30, 2025 compared with $130.2 million(4) for the three months ended March 31, 2025, an increase of $4.9 million or 3.8%. Net income per diluted common share was $1.42 for the three months ended June 30, 2025 compared with $1.37 for the three months ended March 31, 2025. The change was primarily due to an increase in net interest income and a decrease in salaries and benefits. Annualized returns on average assets, average common equity and average tangible common equity for the three months ended June 30, 2025 were 1.41%, 7.13% and 13.44%(1), respectively. Prosperity's efficiency ratio (excluding net gains and losses on the sale, write-down or write-up of assets and securities) was 44.80%(1) for the three months ended June 30, 2025.

Net interest income before provision for credit losses was $267.7 million for the three months ended June 30, 2025 compared with $258.8 million for the same period in 2024, an increase of $8.9 million or 3.5%. The change was primarily due to a decrease in the average balances and average rates on other borrowings and a decrease in the average rates on interest-bearing deposits, partially offset by a decrease in the average rates on loans, a decrease in the average balances on investment securities and a decrease in the average balances and average rates on federal funds sold and other earning assets. Net interest income before provision for credit losses increased $2.3 million to $267.7 million for the three months ended June 30, 2025 compared with $265.4 million for the three months ended March 31, 2025.

The net interest margin on a tax equivalent basis was 3.18% for the three months ended June 30, 2025 compared with 2.94% for the same period in 2024. The change was primarily due to a decrease in the average balances and average rates on other borrowings and a decrease in the average rates on interest-bearing deposits, partially offset by a decrease in the average rates on loans and a decrease in the average balances on investment securities. The net interest margin on a tax equivalent basis was 3.18% for the three months ended June 30, 2025 compared with 3.14% for the three months ended March 31, 2025.

Noninterest income was $43.0 million for the three months ended June 30, 2025 compared with $46.0 million for the same period in 2024, a decrease of $3.0 million or 6.6%. The change was primarily due to a decrease in net gain on sale or write-down of securities, partially offset by an increase in other noninterest income, increase in service charges on deposit accounts and a higher net gain on sale or write-down of assets. Noninterest income was $43.0 million for the three months ended June 30, 2025 compared with $41.3 million for the three months ended March 31, 2025, an increase of $1.7 million or 4.1%.

Noninterest expense was $138.6 million for the three months ended June 30, 2025 compared with $152.8 million for the same period in 2024, a decrease of $14.3 million or 9.3%. The change was primarily due to decreases in regulatory assessment and FDIC insurance, merger related expenses, salaries and benefits and other noninterest expense, which were higher in the second quarter of 2024 due to the merger of Lone Star State Bancshares, Inc. with Prosperity Bancshares and the merger of Lone Star State Bank of West Texas with Prosperity Bank, both effective on April 1, 2024 (collectively, the "Lone Star Merger"). Noninterest expense was $138.6 million for the three months ended June 30, 2025 compared with $140.3 million for the three months ended March 31, 2025, a decrease of $1.7 million or 1.2%.

Net income per diluted common share was $2.79 for the six months ended June 30, 2025 compared with $2.34 for the same period in 2024, an increase of 19.2%. The changes were primarily due to an increase in net interest income, lower merger related provision and expenses, and lower regulatory assessments and FDIC insurance, partially offset by a decrease on net gain on sale or write-up of securities. Returns on average assets, average common equity and average tangible common equity for the six months ended June 30, 2025 were 1.37%, 7.03% and 13.33%(1), respectively.

The net interest margin on a tax equivalent basis for the six months ended June 30, 2025 was 3.16% compared with 2.87% for the same period in 2024.

Balance Sheet Information

Prosperity had $38.417 billion in total assets at June 30, 2025 compared with $39.762 billion at June 30, 2024 and $38.765 billion at March 31, 2025.

Prosperity generally experiences seasonality with its public fund deposits, as public fund customers use the tax dollars they receive in December and January throughout the year, resulting in lower deposit balances in the second and third quarters of the year.

Non-GAAP Financial Measures

Prosperity's management uses certain non-GAAP 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, Federal Deposit Insurance Corporation ("FDIC") special assessment, net of tax, and net gain on the 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. Prosperity believes these non-GAAP financial measures provide information useful to investors in understanding Prosperity's financial results and their presentation, together with the accompanying reconciliations, provides a more complete understanding of factors and trends affecting Prosperity's business and allows investors to view performance in a manner similar to management, the entire financial services sector, bank stock analysts and bank regulators. 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. These non-GAAP financial measures should not be considered a substitute for, nor of greater importance than, GAAP basis financial measures and results; Prosperity strongly encourages investors to review its consolidated financial statements in their entirety and not to rely on any single financial measure. 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.
