From time to time, oral or written forward-looking statements may also be included in information released to the public.

Net income per diluted common share was $1.16 for the quarter ended March 31, 2026, compared with $1.37 for the same period in 2025. On January 1, 2026, American Bank Holding Corporation ("American") merged with Prosperity Bancshares and American Bank, N.A. ("American Bank") merged with Prosperity Bank (collectively, the "American Merger"), and on February 1, 2026, Southwest Bancshares, Inc. ("Southwest") merged with Prosperity Bancshares and Texas Partners Bank ("Texas Partners") merged with Prosperity Bank (collectively, the "Southwest Merger", and together with the American Merger, the "Mergers"). During the first quarter of 2026, Prosperity incurred merger related expenses of $42.5 million, or $0.34(1)per diluted common share. Excluding these charges, net income was $149.9(1) million and earnings per diluted common share was $1.50(1) for the first quarter of 2026. Additionally, during the first quarter of 2026, loans, excluding Warehouse Purchase Program loans, increased $3.354 billion or 16.4%, and deposits increased $4.150 billion or 14.6%, with both increases primarily due to the Mergers. The annualized return on first quarter average assets was 1.10%. Nonperforming assets remain low at 0.33% of first quarter average interest-earning assets."The first quarter of 2026 was impactful for the company and I am excited to announce that during the quarter we completed the merger of American Bank Holding Corporation on January 1, 2026, completed the merger of Southwest Bancshares, Inc. on February 1, 2026 and announced the merger of Stellar Bancorp, Inc. on January 28, 2026, for which we have now received all necessary regulatory approvals and expect to complete on July 1, 2026. Additionally, we completed a core system conversion in February," said David Zalman, Prosperity's Senior Chairman and Chief Executive Officer."We and others believe that Prosperity is doing the right thing. Prosperity has been ranked as one of Forbes America's Best Banks for 2026, and since the list's inception in 2010, was ranked in the Top 10 for 14 consecutive years. Prosperity has also been recognized by Newsweek as one of "America's Best Regional Banks" and was ranked 15th in S&P Global Market Intelligence's "Top 50 US Public Bank Ranking" for 2025," continued Zalman."In an effort to continue to enhance shareholder value, Prosperity Bancshares repurchased approximately 837,000 shares of its common stock at an average weighted price of $68.15 per share for a total of $57.1 million during the first quarter of 2026," added Zalman."Texas and Oklahoma continue to benefit from strong economies and are home to 57 Fortune 500 headquartered companies. Texas also benefits from diversification in various industries, including energy (oil, gas, renewables), technology, manufacturing, trade/logistics (major ports), healthcare and finance. Further, its business-friendly environment, no state income tax, population growth that support spending and workforce expansion and key role in trade and cross-border commerce position it well for 2026 and the future," stated Zalman."While Texas continues to outperform the Unites States on output growth, the labor market has cooled after years of expansion. The growth in 2026 is expected to be steady, although the state's size, diversity and policy advantages position it well for a rebound," concluded Zalman. Results of Operations for the Three Months Ended March 31, 2026For the three months ended March 31, 2026, net income was $116.3 million(2) or  $1.16 per diluted common share compared with $130.2 million(3) or  $1.37 per diluted common share for the same period in 2025.

The webcast may be accessed from Prosperity's Investor Relations page by selecting "Presentations, Webcasts & Calls" from the menu and following the instructions.Non-GAAP Financial MeasuresProsperity'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, and FDIC special assessment, 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 the efficiency ratio, excluding net gains and losses on the sale, write-down or write-up of assets, 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. 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.Prosperity Bancshares, Inc. ®As of March 31, 2026, Prosperity Bancshares, Inc.® is a $43.619 billion Houston, Texas based regional financial holding company providing personal banking services and investments to consumers and businesses throughout Texas and Oklahoma.

("Prosperity") and Stellar Bancorp, Inc. ("Stellar"); future financial and operating results; benefits and synergies of the proposed transaction; future opportunities for Prosperity; the issuance of common stock of Prosperity contemplated by the Agreement and Plan of Merger by and between Prosperity and Stellar (the "Merger Agreement"); the expected timing of the closing of the proposed transaction contemplated by the Merger Agreement; the ability of the parties to complete the proposed transaction considering the various closing conditions and any other statements about future expectations that constitute forward-looking statements within the meaning of the federal securities laws, including the meaning of the Private Securities Litigation Reform Act of 1995, as amended, Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), 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, Stellar and their respective subsidiaries or related to the proposed transaction between Prosperity and Stellar and are subject to significant risks and uncertainties that could cause actual results to differ materially from the results expressed in such statements.These forward-looking statements may include information about Prosperity's and Stellar's possible or assumed future economic performance or future results of operations, including future revenues, income, expenses, provision for loan losses, provision for taxes, effective tax rate, earnings per share and cash flows and Prosperity's and Stellar's future capital expenditures and dividends, future financial condition and changes therein, including changes in Prosperity's and Stellar's loan portfolio and allowance for loan losses, future capital structure or changes therein, as well as the plans and objectives of management for Prosperity's and Stellar's future operations, future or proposed acquisitions, the future or expected effect of acquisitions on Prosperity's and Stellar's operations, results of operations, financial condition, and future economic performance, statements about the anticipated benefits of the proposed transaction, 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 the control of Prosperity and Stellar, 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); 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. Many possible events or factors could adversely affect the future financial results and performance of Prosperity, Stellar or the combined company and could cause those results or performance to differ materially from those expressed in or implied by the forward-looking statements. Such risks and uncertainties include, among others: (1) the risk that the cost savings and synergies from the proposed transaction may not be fully realized or may take longer than anticipated to be realized, (2) disruption to Prosperity's and Stellar's businesses as a result of the announcements and pendency of the proposed transaction, (3) the risk that the integration of Stellar's businesses and operations into Prosperity will be materially delayed or will be more costly or difficult than expected, or that Prosperity is otherwise unable to successfully integrate Stellar's business into its own, including as a result of unexpected factors or events, (4) the failure to obtain the necessary approval by the shareholders of Stellar, (5) reputational risk and the reaction of each company's customers, suppliers, employees or other business partners to the proposed transaction, (6) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing the proposed transaction or the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, (7) the dilution caused by the issuances of additional shares of Prosperity's common stock in the proposed transaction, (8) the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (9) the outcome of any legal or regulatory proceedings that may be currently pending or later instituted against Prosperity before or after the proposed transaction, or against Stellar, (10) diversion of management's attention from ongoing business operations and (11) general competitive, economic, political and market conditions and other factors that may affect future results of Prosperity and Stellar. Prosperity and Stellar disclaim 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 risks, uncertainties, assumptions, and factors are discussed in the respective Annual Reports on Form 10-K for the year ended December 31, 2025, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K, filed by Prosperity or Stellar and in other filings made by Prosperity and Stellar with the Securities and Exchange Commission (the "SEC") from time to time.Additional Information about the Transaction and Where to Find ItIn connection with the proposed transaction, Prosperity has filed with the SEC a registration statement (the "Registration Statement") on Form S-4 (File No. 333-294882) to register the shares of Prosperity common stock to be issued to the shareholders of Stellar in connection with the proposed transaction.

Notes to Selected Financial Data (Unaudited)
(Dollars and share amounts in thousands, except per share data)NOTES TO SELECTED FINANCIAL DATAProsperity'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 expenses, net of tax, and FDIC special assessment, 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 the efficiency ratio, excluding net gains and losses on the sale, write-down or write-up of assets, 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.

Net income per diluted common share was $1.49 for the quarter ended December 31, 2025, compared with $1.37 for the same period in 2024. The annualized return on fourth quarter average assets was 1.49%. Additionally, deposits increased $700.4 million during the fourth quarter of 2025. Nonperforming assets remain low at 0.46% of fourth quarter average interest-earning assets. On January 1, 2026, American Bank Holding Corporation ("American") merged with Prosperity Bancshares and American Bank, N.A. ("American Bank") merged with Prosperity Bank (collectively, the "Prosperity/American Merger")."I am excited to announce that on January 1, 2026, Prosperity completed the merger with our new partner American and its wholly owned subsidiary American Bank, headquartered in Corpus Christi, Texas. In connection with that transaction, we are pleased that Patt Wallace, the daughter of one of the founding families of the bank, and Steve Rafaelle, the CEO of American Bank, have joined our Bank Board of Directors," said David Zalman, Prosperity's Senior Chairman and Chief Executive Officer."We have also received all regulatory and shareholder approvals for the merger with Southwest Bancshares, the parent company of Texas Partners Bank and expect the transaction will be effective on February 1, 2026. In connection with the Southwest deal, we are pleased that Gene Dawson, Interim Chairman of Southwest Bancshares and Chairman of the nationally recognized Pape-Dawson engineering firm will be joining our Bank Board of Directors. To further add to our San Antonio presence, Charlie Amato has joined our Bank Board of Directors. In addition to his successful business, Charlie previously served as a board member of Federal Reserve Board of Dallas, San Antonio Branch, a Regent of the Texas State University System and is an investor in the San Antonio Spurs," continued Zalman."When Prosperity went public in 1998, we were a small community bank in rural Texas with less than $500 million in assets. For 27 years, we have remained disciplined and focused on the same strategy. Delivering shareholder value by prioritizing low-cost core deposits, operational efficiency, sound credit quality, and growth via opportunistic M&A," added Zalman."This morning's announcement that Prosperity is acquiring Stellar Bancorp is consistent with that strategy and this transaction marks an important milestone for the company. Our combined Houston bank deposit rank increases from number 9 to number 5, making us the largest Texas-based bank in the market and 2nd largest by bank deposits in the state," stated Zalman."Importantly, Stellar Bancorp is a well-run bank with similar credit discipline and an envious noninterest-bearing deposit mix. It has scarcity value, a quality balance sheet and earnings power. As a result, we view the transaction as a low-risk combination that significantly enhances our Texas footprint," concluded Zalman.Results of Operations for the Three Months Ended December 31, 2025Net income was $139.9 million(2) for the three months ended December 31, 2025, compared with $130.1 million(3) for the same period in 2024, an increase of $9.8 million or 7.6%. Net income per diluted common share was $1.49 for the three months ended December 31, 2025, compared with $1.37 for the same period in 2024, an increase of 8.8%. The changes were primarily due to an increase in net interest income and a decrease in Federal Deposit Insurance Corporation ("FDIC") special assessment, partially offset by an increase in provision for income taxes. On a linked quarter basis, net income was $139.9 million(2) for the three months ended December 31, 2025, compared with $137.6 million(4) for the three months ended September 30, 2025, an increase of $2.4 million or 1.7%. Net income per diluted common share was $1.49 for the three months ended December 31, 2025, compared with $1.45 for the three months ended September 30, 2025, an increase of 2.8%. Annualized returns on average assets, average common equity and average tangible common equity for the three months ended December 31, 2025, were 1.49%, 7.30% and 13.61%(1), respectively. Prosperity's efficiency ratio (excluding net gains and losses on the sale, write-down or write-up of assets and securities) was 43.66%(1) for the three months ended December 31, 2025.Net interest income before provision for credit losses was $275.0 million for the three months ended December 31, 2025, compared with $267.8 million for the same period in 2024, an increase of $7.2 million or 2.7%. The net interest margin on a tax equivalent basis was 3.30% for the three months ended December 31, 2025, compared with 3.05% for the same period in 2024. The changes to both measures were 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 balances and average rates on loans and federal funds sold and other earning assets. Net interest income before provision for credit losses increased $1.5 million to $275.0 million for the three months ended December 31, 2025, compared with $273.4 million for the three months ended September 30, 2025. The net interest margin on a tax equivalent basis was 3.30% for the three months ended December 31, 2025, compared with 3.24% for the three months ended September 30, 2025. The changes to both measures were primarily due to a decrease in the average balances and average rates on other borrowings, partially offset by a decrease in the average balances and average rates on loans and federal funds sold and other earning assets.Noninterest income was $42.8 million for the three months ended December 31, 2025, compared with $39.8 million for the same period in 2024, an increase of $2.9 million, primarily due to increases in other noninterest income and service charges on deposit accounts. Noninterest income was $42.8 million for the three months ended December 31, 2025, compared with $41.2 million for the three months ended September 30, 2025, an increase of $1.5 million.Noninterest expense was $138.7 million for the three months ended December 31, 2025, compared with $141.5 million for the same period in 2024, a decrease of $2.8 million, primarily due to a reversal of the 2024 FDIC special assessment, partially offset by a change in the net loss on sale or write-down of other real estate and an excise tax expense due to stock repurchases. Noninterest expense was $138.7 million for the three months ended December 31, 2025, and $138.6 million for the three months ended September 30, 2025.Results of Operations for the Year Ended December 31, 2025For the year ended December 31, 2025, net income was $542.8 million(5) compared with $479.4 million(6) for the same period in 2024, an increase of $63.5 million or 13.2%. Net income per diluted common share was $5.72 for the year ended December 31, 2025, compared with $5.05 for the same period in 2024, an increase of 13.3%. 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 in net gain on sale or write-up of securities. Returns on average assets, average common equity and average tangible common equity for the year ended December 31, 2025, were 1.42%, 7.14% and 13.43%(1), respectively.Net interest income before provision for credit losses for the year ended December 31, 2025, was $1.081 billion compared with $1.026 billion for the same period in 2024, an increase of $55.0 million or 5.4%. The net interest margin on a tax equivalent basis for the year ended December 31, 2025, was 3.22% compared with 2.93% for the same period in 2024. The changes to both measures were 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 balances and average rates on federal funds sold and other earning assets, a decrease in the average balances on investment securities, a decrease in the average rates on loans and a decrease in loan discount accretion of $5.1 million.Noninterest income was $168.3 million for the year ended December 31, 2025, compared with $165.8 million for the same period in 2024, an increase of $2.5 million, primarily due to increases in other noninterest income and service charges on deposit accounts, partially offset by a decrease in net gain on sale or write-up of securities. Noninterest expense was $556.2 million for the year ended December 31, 2025, compared with $570.6 million for the same period in 2024, a decrease of $14.4 million, primarily due lower regulatory assessments and FDIC insurance, a reversal of the 2024 FDIC special assessment, a decrease in other noninterest expense and a decrease in merger related expenses.Balance Sheet InformationProsperity had $38.463 billion in total assets at December 31, 2025, compared with $38.330 billion at September 30, 2025, and $39.567 billion at December 31, 2024.

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 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.Prosperity Bancshares, Inc. ®As of December 31, 2025, Prosperity Bancshares, Inc.® is a $38.463 billion Houston, Texas based regional financial holding company providing personal banking services and investments to consumers and businesses throughout Texas and Oklahoma.

("Prosperity") and Stellar Bancorp, Inc. ("Stellar"); future financial and operating results; benefits and synergies of the proposed transaction; future opportunities for Prosperity; the issuance of common stock of Prosperity contemplated by the Agreement and Plan of Merger by and between Prosperity and Stellar (the "Merger Agreement"); the expected filing by Prosperity with the Securities and Exchange Commission (the "SEC") of a registration statement on Form S-4 (the "Registration Statement") and a prospectus of Prosperity and a proxy statement of Stellar to be included therein (the "Proxy Statement/Prospectus"); the expected timing of the closing of the proposed transaction; the ability of the parties to complete the proposed transaction considering the various closing conditions and any other statements about future expectations that constitute forward-looking statements within the meaning of the federal securities laws, including the meaning of the Private Securities Litigation Reform Act of 1995, as amended, Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), 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, Stellar and their respective subsidiaries or related to the proposed transaction between Prosperity and Stellar and are subject to significant risks and uncertainties that could cause actual results to differ materially from the results expressed in such statements. These forward-looking statements may include information about Prosperity's and Stellar's possible or assumed future economic performance or future results of operations, including future revenues, income, expenses, provision for loan losses, provision for taxes, effective tax rate, earnings per share and cash flows and Prosperity's and Stellar's future capital expenditures and dividends, future financial condition and changes therein, including changes in Prosperity's and Stellar's loan portfolio and allowance for loan losses, future capital structure or changes therein, as well as the plans and objectives of management for Prosperity's and Stellar's future operations, future or proposed acquisitions, the future or expected effect of acquisitions on Prosperity's and Stellar's operations, results of operations, financial condition, and future economic performance, statements about the anticipated benefits of the proposed transaction, 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 and Stellar currently believe to be valid. Because forward-looking statements relate to future results and occurrences, many of which are outside of the control of Prosperity and Stellar, 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); 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. Many possible events or factors could adversely affect the future financial results and performance of Prosperity, Stellar or the combined company and could cause those results or performance to differ materially from those expressed in or implied by the forward-looking statements. Such risks and uncertainties include, among others: (1) the risk that the cost savings and synergies from the proposed transaction may not be fully realized or may take longer than anticipated to be realized, (2) disruption to Prosperity's and Stellar's businesses as a result of the announcements and pendency of the proposed transaction, (3) the risk that the integration of Stellar's businesses and operations into Prosperity will be materially delayed or will be more costly or difficult than expected, or that Prosperity is otherwise unable to successfully integrate Stellar's business into its own, including as a result of unexpected factors or events, (4) the failure to obtain the necessary approval by the shareholders of Stellar, (5) the ability by Prosperity and/or Stellar to obtain required governmental approvals of the proposed transaction on the timeline expected, or at all, and the risk that such approvals may result in the imposition of conditions that could adversely affect Prosperity after the closing of the proposed transaction or adversely affect the expected benefits of the proposed transaction, (6) reputational risk and the reaction of each company's customers, suppliers, employees or other business partners to the proposed transaction, (7) the failure of the closing conditions in the Merger Agreement to be satisfied, or any unexpected delay in closing the proposed transaction or the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement, (8) the dilution caused by the issuances of additional shares of Prosperity's common stock in the proposed transaction, (9) the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (10) the outcome of any legal or regulatory proceedings that may be currently pending or later instituted against Prosperity before or after the proposed transaction, or against Stellar, (11) diversion of management's attention from ongoing business operations and (12) general competitive, economic, political and market conditions and other factors that may affect future results of Prosperity and Stellar.

Notes to Selected Financial Data (Unaudited)
(Dollars and share amounts in thousands, except per share data)NOTES TO SELECTED FINANCIAL DATAProsperity'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.
