"Each year, Forbes assesses the 100 largest banks in the United States on growth, credit quality and earnings, as well as other factors, for its America's Best Banks list.  Prosperity Bank has been ranked in the Top 10 since the list's inception in 2010.  We have twice been ranked number 1, were ranked number 2 in 2021 and are ranked number 6 for 2022.  It is a testament to Prosperity's performance, culture, vision and consistency and distinguishes us among most banks" said David Zalman, Prosperity's Senior Chairman and Chief Executive Officer.

"I wish to congratulate and thank all our customers, associates and directors for helping us achieve this great honor," added Zalman.

"Prosperity has a talented team, deep bench, strong earnings, a solid capital position and a fortress balance sheet.  We will continue working to help our customers and associates succeed and to build shareholder value," concluded Zalman.

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

Net income was $122.3 million⁽²⁾ for the three months ended March 31, 2022 compared with $133.3 million⁽³⁾ for the same period in 2021. The change was primarily due to a decrease in loan interest income (including a decrease in PPP fees) and loan discount accretion of $11.1 million, partially offset by an increase in securities interest income and a decrease in interest expense. Net income per diluted common share was $1.33 for the three months ended March 31, 2022 compared with $1.44 for the same period in 2021. On a linked quarter basis, net income was $122.3 million⁽²⁾ for the three months ended March 31, 2022 compared with $126.8 million⁽⁴⁾ for the three months ended December 31, 2021. The change was primarily due to a decrease in loan interest income (including a decrease in PPP fees), partially offset by an increase in securities interest income. Net income per diluted common share was $1.33 for the three months ended March 31, 2022 compared with $1.38 for the three months ended December 31, 2021. Annualized returns on average assets, average common equity and average tangible common equity for the three months ended March 31, 2022 were 1.29%, 7.54% and 15.30%⁽¹⁾, respectively. Prosperity's efficiency ratio (excluding net gains and losses on the sale or write down of assets and securities) was 43.68%⁽¹⁾ for the three months ended March 31, 2022.

Net interest income before provision for credit losses for the three months ended March 31, 2022 was $239.9 million compared with $254.6 million for the same period in 2021. The change was primarily due to a decrease in the average balance and average rate on loans and a decrease in loan discount accretion of $11.1 million, partially offset by an increase in the average investment securities balance and a decrease in the average rate on interest-bearing liabilities. On a linked quarter basis, net interest income before provision for credit losses was $239.9 million compared with $244.8 million for the three months ended December 31, 2021.

The net interest margin on a tax equivalent basis was 2.88% for the three months ended March 31, 2022 compared with 3.41% for the same period in 2021. The change was primarily due to lower average rates on loans, a decrease in loan discount accretion of $11.1 million and an increase in the average balance on investment securities, partially offset by a decrease in the average rate on interest-bearing liabilities. On a linked quarter basis, the net interest margin on a tax equivalent basis was 2.88% for the three months ended March 31, 2022 compared with 2.97% for the three months ended December 31, 2021. The change was primarily due to lower average rates on loans and higher cash balances due to excess liquidity, partially offset by higher average balance and rates on investment securities.

Noninterest income was $35.1 million for the three months ended March 31, 2022 compared with $34.0 million for the same period in 2021, an increase of $1.1 million or 3.3%. This change was primarily due to an increase in nonsufficient funds fees, an increase in other noninterest income and a net gain on the sale of assets, partially offset by a decrease in mortgage income. On a linked quarter basis, noninterest income was $35.1 million compared with $35.8 million for the three months ended December 31, 2021.

Noninterest expense was $119.9 million for the three months ended March 31, 2022 compared with $119.1 million for the same period in 2021 and $119.5 million for the three months ended December 31, 2021.

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.
