I am also pleased to announce that in connection with the mergers, Robert Franklin, former CEO of Stellar, and Joe Swinbank, a former Stellar director, have ______________ (1)Refer to the “Notes to Selected Financial Data” at the end of this Earnings Release for a reconciliation of this non-GAAP financial measure to the nearest GAAP financial measure. Page 1 joined the Prosperity Bancshares Board of Directors and that Ray Vitulli, former CEO of Stellar Bank, and Pat Parsons, a former Stellar Bank director, have joined the Prosperity Bank Board of Directors. Pat was instrumental in building Stellar Bank’s Beaumont franchise over the years,” said David Zalman, Prosperity’s Senior Chairman and Chief Executive Officer. “Texas has one of the strongest and most diverse state economies in the U.S., ranking as the second largest by GDP after California and approximately the 8th largest economy in the world. Oklahoma has a smaller but stable economy, heavily influenced by oil and gas, with more modest growth. Texas continues to shine as more people and companies move to the state because of the business-friendly political structure and no state income tax,” stated Zalman. “Excluding the gain on Visa Class B-2 stock exchange net of investment securities sales and merger related expenses, as noted above, net income increased 20.4% and diluted earnings per share increased 14.1% compared with the same period last year,” added Zalman. “We are pleased with our growth. Giving effect to the Stellar Bank merger, our assets are over $53 billion compared with $38 billion as of June 30, 2025. This represents a 39% growth over the year. I want to thank everyone involved in our company for helping to make it the success it has become,” concluded Zalman. Results of Operations for the Three Months Ended June 30, 2026 For the three months ended June 30, 2026, net income was $168.6 million(2) or $1.67 per diluted common share compared with $135.2 million(3)or $1.42 per diluted common share for the same period in 2025. Net income and net income per diluted common share for the second quarter of 2026 were primarily impacted by an increase in net interest income and a gain on Visa Class B-2 stock exchange net of investment securities sales of $8.2 million, partially offset by an increase in noninterest expenses related to the American and Southwest operations and an increase in provision for income taxes. On a linked quarter basis, net income was $168.6 million(2) or $1.67 per diluted common share for the three months ended June 30, 2026, compared with $116.3 million(4) or $1.16 for the three months ended March 31, 2026. The change was primarily due to an increase in net interest income, lower merger related expenses and a gain on Visa Class B-2 stock exchange net of investment securities sales of $8.2 million. Annualized returns on average assets, average common equity and average tangible common equity for the three months ended June 30, 2026, were 1.55%, 8.14% and 15.48%(1), respectively.

The net interest margin on a tax equivalent basis was 3.47% for the three months ended June 30, 2026, compared with 3.18% for the same period in 2025. The changes to both measures were primarily due to the repricing of assets, a decrease in the average balance and average rate on other borrowings and the impact of the American Merger and the Southwest Merger. Net interest income before provision for credit losses increased $9.4 million or 2.9% to $330.6 million for the three months ended June 30, 2026, compared with $321.2 million for the three months ended March 31, 2026. The net interest margin on a tax equivalent basis was 3.47% for the three months ended June 30, 2026, compared with 3.51% for the three months ended March 31, 2026. The decrease was primarily due to one-time loan interest income from a nonaccrual loan in the first quarter of 2026.

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 expenses, net of tax, FDIC special assessment, net of tax and net gain on the sale or write-up of securities; 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 and securities, write-down or write-up of assets; 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, provide a more complete understanding of factors and trends affecting Prosperity’s business and allow 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.

Cautionary Notes on Forward-Looking Statements “Safe Harbor” Statement under the Private Securities Litigation Reform Act of 1995: This release contains, and the remarks by Prosperity’s management on the conference call may contain, forward-looking statements within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. From time to time, oral or written forward-looking statements may also be included in other information released to the public. Such forward-looking statements are typically, but not exclusively, identified by the use in the statements of words or phrases such as “aim,” “anticipate,” “believe,” “estimate,” “expect,” “goal,” “guidance,” “intend,” “is anticipated,” “is expected,” “is intended,” “objective,” “plan,” “projected,” “projection,” “will affect,” “will be,” “will continue,” “will decrease,” “will grow,” “will impact,” “will increase,” “will incur,” “will reduce,” “will remain,” “will result,” “would be,” variations of such words or phrases (including where the word “could,” “may,” or “would” is used rather than the word “will” in a phrase) and similar words and phrases indicating that the statement addresses some future result, occurrence, plan or objective. Forward-looking statements include all statements other than statements of historical fact, including forecasts or trends, and are based on current expectations, assumptions, estimates and projections about Prosperity Bancshares and its subsidiaries. These forward-looking statements may include information about Prosperity’s possible or assumed future economic performance or future results of operations, including future revenues, income, expenses, provision for credit losses, provision for taxes, effective tax rate, earnings per share and cash flows and Prosperity’s future capital expenditures and dividends, future financial condition and changes therein, including changes in Prosperity’s loan portfolio and allowance for credit losses, changes in deposits, borrowings and the investment securities portfolio, future capital structure or changes therein, as well as the plans and objectives of management for Prosperity’s future operations, future or proposed acquisitions, the future or expected effect of acquisitions on Prosperity’s operations, results of operations, financial condition, and future economic performance, statements about the anticipated benefits of any proposed transactions, and statements about the assumptions underlying any such statement. These forward‑looking statements are not guarantees of future performance and are based on expectations and assumptions Prosperity currently believes to be valid. Because forward-looking statements relate to future results and occurrences, many of which are outside of Prosperity’s control, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. These risks and uncertainties include, but are not limited to, whether Prosperity can: successfully identify acquisition targets and integrate the businesses of acquired companies and banks; continue to sustain its current internal growth rate or total growth rate; provide products and services that appeal to its customers; continue to have access to debt and equity capital markets; and achieve its sales objectives. Other risks include, but are not limited to: the possibility that credit quality could deteriorate; actions of competitors; changes in laws and regulations (including changes in governmental interpretations of regulations and changes in accounting standards); the possibility that the anticipated benefits of an acquisition transaction are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of two companies or as a result of the strength of the economy and competitive factors generally; a deterioration or downgrade in the credit quality and credit agency ratings of the securities in Prosperity’s securities portfolio; customer and consumer demand, including customer and consumer response to marketing; effectiveness of spending, investments or programs; fluctuations in the cost and availability of supply chain resources; economic conditions, including currency rate, interest rate and commodity price fluctuations; changes in trade policies by the United States or other countries, such as tariffs or retaliatory tariffs; and the effect, impact, potential duration or other implications of weather and climate-related events. Prosperity disclaims any obligation to update such factors or to publicly announce the results of any revisions to any of the forward-looking statements included herein to reflect future events or developments. These and various other factors are discussed in Prosperity’s Annual Report on Form 10-K for the year ended December 31, 2025, and other reports and statements Prosperity has filed with the Securities and Exchange Commission (“SEC”).
