HOUSTON, October 23, 2024.

Net income per diluted common share was $1.34 for the quarter ended September 30, 2024 compared with $1.20 for the same period in 2023.

“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. Our tangible capital increased $218 million from September 30, 2023, to September 30, 2024. This is the amount Prosperity retained after paying $212 million in dividends and repurchasing $75 million of our common stock during this period, reflecting Prosperity’s stable earnings. Further, Prosperity’s tangible book value per share has a compound annual growth rate of 11% for the last 21 years, or since 2003,” added Zalman.

“The $2.4 trillion Texas economy is the eighth-largest among the nations of the world, larger than Russia, Canada and Italy, among others. An estimated 1,000 to 1,300 people move to Texas every day. Based on US Census Bureau data, in 2023, 473,453 people moved to Texas, which equates to approximately 40,000 per month or 1,300 per day,” added Zalman.

“The Texas and Oklahoma economies continue to benefit from companies relocating from states with higher taxes and more regulation. This, combined with people moving to the states, requires additional housing and infrastructure, a driver for loans and increased business opportunities. We believe our bank is located in two of the best states we can be for future growth and continued prosperity,” concluded Zalman.

Results of Operations for the Three Months Ended September 30, 2024

For the three months ended September 30, 2024, net income was $127.3 million(2) or $1.34 per diluted common share compared with $112.2 million(3) or $1.20 per diluted common share for the same period in 2023, an increase of $15.1 million or 13.4%. The change was primarily due to an increase in net interest income, partially offset by an increase in noninterest expense related to three months of Lone Star Bank operations. For the three months ended September 30, 2024, net income was $127.3 million(2) or $1.34 per diluted common share compared with $111.6 million(4) or $1.17 per diluted common share for the three months ended June 30, 2024, an increase of $15.7 million or 14.0%. The change was primarily due to higher net interest income, lower merger related provision for credit losses and lower merger related expenses, partially offset by lower net gain on sale or write-up of securities. Annualized returns on average assets, average common equity and average tangible common equity for the three months ended September 30, 2024 were 1.28%, 6.93% and 13.50%(1), respectively.

The change was primarily due to an increase in the average balances and average rates on loans, an increase in the average balances on federal funds sold and other earning assets and a decrease in the average balances and rate on other borrowings, partially offset by a decrease in the average balances on investment securities and an increase in the average balances and rates on interest-bearing deposits. Net interest income before provision for credit losses increased $2.9 million or 1.1% to $261.7 million for the three months ended September 30, 2024 compared with $258.8 million for the three months ended June 30, 2024.

The net interest margin on a tax equivalent basis was 2.95% for the three months ended September 30, 2024 compared with 2.72% for the same period in 2023 and 2.94% for the three months ended June 30, 2024. The year-to-year change was primarily due to an increase in the average balances and average rates on loans, an increase in the average balances on federal funds sold and other earning assets and a decrease in the average balances and rate on other borrowings, partially offset by a decrease in the average balances on investment securities and an increase in the average balances and rates on interest-bearing deposits.

Noninterest income was $41.1 million for the three months ended September 30, 2024 compared $38.7 million for the same period in 2023, an increase of $2.4 million or 6.1%. The change was primarily due to an increase in the net gain (loss) on sale or write-down of assets, partially offset by a decrease in other noninterest income. Noninterest income was $41.1 million for the three months ended September 30, 2024 compared with $46.0 million for the three months ended June 30, 2024, a decrease of $4.9 million or 10.7%. The change was primarily due to lower net gain on sale or write-up of securities, partially offset by an increase in net gain (loss) on sale or write-down of assets.

Noninterest expense was $140.3 million for the three months ended September 30, 2024 compared with $135.7 million for the same period in 2023, an increase of $4.7 million or 3.5%, primarily due to an increase in salaries and benefits, an increase in credit and debit card, data processing and software amortization, and additional expenses related to three months of Lone Star Bank operations, partially offset by a decrease in merger related expenses.

The change was primarily due to an increase in the average balances and average rates on loans, an increase in the average balances and average rates on federal funds sold and other earning assets, an increase in loan discount accretion and a decrease in the average rates on other borrowings, partially offset by a decrease in the average balances on investment securities and an increase in the average balances and rates on interest-bearing deposits.

The net interest margin on a tax equivalent basis for the nine months ended September 30, 2024 was 2.86% compared with 2.79% for the same period in 2023. The change was primarily due to an increase in the average balances and average rates on loans, an increase in the average balances and average rates on federal funds sold and other earning assets, an increase in loan discount accretion and a decrease in the average rates on other borrowings, partially offset by a decrease in the average balances on investment securities and an increase in the average balances and rates on interest-bearing deposits. The increases in the average balances on loans and deposits were primarily due to the LSSB Merger.

Noninterest income was $126.0 million for the nine months ended September 30, 2024 compared with $116.7 million for the same period in 2023, an increase of $9.3 million or7.9%, primarily due to a gain on Visa Class B-1 stock exchange net of investment securities sales, and an increase in trust income, partially offset by a decrease in other noninterest income.

Noninterest expense was $429.0 million for the nine months ended September 30, 2024 compared with $404.5 million for the same period in 2023, an increase of $24.5 million or 6.1%, primarily due to a FDIC special assessment of $3.6 million, an increase in salaries and benefits and additional expenses related to six months of Lone Star Bank operations and nine months of FirstCapital Bank of Texas, N.A.

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, 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

Page 5

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.

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.

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

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.
