HOUSTON, January 25, 2023. Prosperity Bancshares, Inc.® (NYSE: PB), the parent company of Prosperity Bank® (collectively, “Prosperity”), reported net income of $137.9 million for the quarter ended December 31, 2022 compared with $126.8 million for the same period in 2021. Net income per diluted common share was $1.51 for the quarter ended December 31, 2022 compared with $1.38 for the same period in 2021, an increase of 9.4%, and the annualized return on fourth quarter average assets was 1.47%. Additionally, loans, excluding Warehouse Purchase Program and SBA Paycheck Protection Program (“PPP”) loans, increased $518.5 million or 3.0% (11.8% annualized) during the fourth quarter of 2022. Nonperforming assets remain low at 0.08% of fourth quarter average interest-earning assets.

“During the fourth quarter of 2022, Prosperity continued to see growth in loans, which we expect will continue in 2023. The growth comes from new loans as well as existing loans not paying off as fast as they did when rates were low and it was opportunistic for borrowers to repay or move the loans. Consumer spending remains strong, especially in the tourism, restaurant and hospitality sectors. Real estate sales and pricing have been affected by the increase in rates, but we expect that because of inventory levels and population growth, the impact will be less in Texas and Oklahoma,” said David Zalman, Prosperity’s Senior Chairman and Chief Executive Officer.

"We believe that the economies in Texas and Oklahoma will outperform other states over the next several years as companies and individuals continue to move to the states because of lower tax rates and a business-friendly political environment. We expect that companies will need more infrastructure and buildings and consumers will need more housing and places to spend their money, and both will need banks to finance the growth," continued Zalman.

"While the net interest margin at some banks has improved immediately because of higher rates, we expect Prosperity’s net interest margin to continue to increase over the next several years as our bond portfolio, which yielded 1.96% during the fourth quarter of 2022, reprices to higher yields assuming that rates normalize near the current rate," concluded Zalman.

Results of Operations for the Three Months Ended December 31, 2022

Net income was $137.9 million(2) for the three months ended December 31, 2022 compared with $126.8 million(3) for the same period in 2021, an increase of $11.1 million or 8.7%. The change was primarily due to an increase in loans and securities interest income, partially offset by a decrease in PPP fees and interest income of $8.5 million, a decrease in loan discount accretion of $4.5 million, and an increase in interest expense. Net income per diluted common share was $1.51 for the three months ended December 31, 2022 compared with $1.38 for the same period in 2021, an increase of 9.4%. On a linked quarter basis, net income was $137.9 million(2) for the three months ended December 31, 2022 compared with $135.8 million(4) for the three months ended September 30, 2022, an increase of $2.1 million or 1.5%. The change was primarily due to an increase in noninterest income and a decrease in noninterest expense, partially offset by a decrease in net interest income.

Net interest income before provision for credit losses for the three months ended December 31, 2022 was $256.1 million compared with $244.8 million for the same period in 2021, an increase of $11.4 million or 4.6%. The change was primarily due to an increase in the average balances and average rates on loans held for investment and on investment securities, partially offset by a decrease in PPP fees and interest income of $8.5 million, a decrease in loan discount accretion of $4.5 million and an increase in the average rates on interest-bearing liabilities. On a linked quarter basis, net interest income before provision for credit losses was $256.1 million compared with $260.7 million for the three months ended September 30, 2022, a decrease of $4.5 million or 1.7%.

The net interest margin on a tax equivalent basis was 3.05% for the three months ended December 31, 2022 compared with 2.97% for the same period in 2021.

On a linked quarter basis, the net interest margin on a tax equivalent basis was 3.05% for the three months ended December 31, 2022 compared with 3.11% for the three months ended September 30, 2022. The linked quarter decrease was primarily due to an increase in the average rates on interest-bearing liabilities, partially offset by higher average balances and higher average rates on loans and average rates on investment securities.

Noninterest income was $37.7 million for the three months ended December 31, 2022 compared with $35.8 million for the same period in 2021, an increase of $2.0 million or 5.5%. This change was primarily due to a higher net gain on sale or write-down of assets, an increase in trust income and an increase in other noninterest income. On a linked quarter basis, noninterest income was $37.7 million compared with $34.7 million for the three months ended September 30, 2022, an increase of $3.0 million or 8.8%, primarily due to a higher net gain on the sale or write-down of assets and an increase in other noninterest income.

Conference Call

Prosperity’s management team will host a conference call on Wednesday, January 25, 2023, at 11:30 a.m. Eastern Time (10:30 a.m. Central Time) to discuss Prosperity’s fourth quarter 2022 earnings. Individuals and investment professionals may participate in the call by dialing 877-883-0383 for domestic participants, or 412-902-6506 for international participants. The participant elite entry number is 6262776.

The webcast may be accessed from Prosperity’s home page by selecting “Presentations, Webcasts & Calls” from the menu on the Investor Relations link and following the instructions.

Non-GAAP Financial Measures

Prosperity’s management uses certain non-GAAP financial measures to evaluate its performance. Specifically, Prosperity reviews return on average tangible common equity; tangible book value per share; the tangible equity to tangible assets ratio; allowance for credit losses on loans to total loans excluding Warehouse Purchase Program and PPP loans; and the efficiency ratio excluding net gains and losses on the sale or write down of assets and securities, for internal planning and forecasting purposes. 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.

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. Many possible events or factors could adversely affect the future financial results and performance of Prosperity, First Bancshares, Lone Star 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: the occurrence of any event, change or other circumstance that could give rise to the right of a party to terminate the merger agreement with First Bancshares or Lone Star, as applicable, the outcome of any legal proceedings that may be instituted against Prosperity, First Bancshares or Lone Star, delays in completing either of the transactions, the failure to obtain necessary regulatory approvals (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of each of the transactions) or First Bancshares shareholder approval or Lone Star shareholder approval or to satisfy any of the other conditions to the transactions on a timely basis or at all, the possibility that the anticipated benefits of the transactions are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of the two companies or as a result of the strength of the economy and competitive factors generally, or specifically in the West Texas area and the West, North and Central Texas area where First Bancshares and Lone Star, respectively, do a majority of their respective business and Prosperity has a significant presence, the possibility that the transactions may be more expensive to complete than anticipated, including as a result of unexpected factors or events, diversion of management’s attention from ongoing business operations and opportunities, potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the transactions, Prosperity’s ability to complete the acquisition and integration of First Bancshares and of Lone Star successfully, and the dilution caused by Prosperity’s issuance of additional shares of its common stock in connection with the transactions. 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, 2021, and other reports and statements Prosperity has filed with the Securities and Exchange Commission (“SEC”).

Notes to Selected Financial Data (Unaudited)

NOTES TO SELECTED FINANCIAL DATA

Prosperity’s management uses certain non-GAAP (generally accepted accounting principles) financial measures to evaluate its performance. Specifically, Prosperity reviews return on average tangible common equity; tangible book value per share; the tangible equity to tangible assets ratio; allowance for credit losses on loans to total loans excluding Warehouse Purchase Program and PPP loans; and the efficiency ratio, excluding net gains and losses on the sale or write down of assets and securities, for internal planning and forecasting purposes. 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 on loans to total loans (excluding Warehouse Purchase Program loans and PPP loans). Prosperity has included information below relating to these non-GAAP financial measures for the applicable periods presented.
