HOUSTON, July 27, 2022. Prosperity Bancshares, Inc.® (NYSE: PB), the parent company of Prosperity Bank® (collectively, "Prosperity"), reported net income of $128.5 million for the quarter ended June 30, 2022 compared with $130.6 million for the same period in 2021. Net income per diluted common share was $1.40 for the quarter ended June 30, 2022 compared with $1.41 for the same period in 2021, and the annualized return on second quarter average assets was 1.36%. Additionally, loans, excluding Warehouse Purchase Program and SBA Paycheck Protection Program ("PPP") loans, increased $406.9 million or 2.4% (9.8% annualized) during the second quarter of 2022. Nonperforming assets remain low at 0.07% of second quarter average interest-earning assets.

"We experienced a strong second quarter of 2022. Earnings increased 5.0% compared with the first quarter of 2022 and we expect continued earnings growth as interest rates increase. Further, our core loans, excluding Warehouse Purchase Program and SBA Paycheck Protection Program loans, grew $406.9 million or 2.4% (9.8% annualized) during the quarter, while our non-performing loans remained very low," said David Zalman, Prosperity's Senior Chairman and Chief Executive Officer.

"Texas and Oklahoma continue to shine as more people and companies move to these states. For example, according to CNBC, Texas added more jobs over the last year than the 25 lowest job growth states combined. Further, during the last year, the Dallas-Fort Worth area added 295,000 jobs, three times its average annual growth, and the Houston area added 185,000 jobs. Unemployment remains unusually low," continued Zalman.

Results of Operations for the Three Months Ended June 30, 2022

Net income was $128.5 million(2) for the three months ended June 30, 2022 compared with $130.6 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 interest income of $10.4 million) and loan discount accretion of $12.1 million, partially offset by an increase in securities interest income and a decrease in interest expense. Net income per diluted common share was $1.40 for the three months ended June 30, 2022 compared with $1.41 for the same period in 2021. On a linked quarter basis, net income was $128.5 million(2) for the three months ended June 30, 2022 compared with $122.3 million(4) for the three months ended March 31, 2022, an increase of $6.2 million or 5.0%. The change was primarily due to an increase in securities interest income, partially offset by a decrease in loan discount accretion of $5.1 million.

Annualized returns on average assets, average common equity and average tangible common equity for the three months ended June 30, 2022 were 1.36%, 7.84% and 15.73%(1), respectively. Prosperity's efficiency ratio (excluding net gains and losses on the sale or write down of assets and securities) was 43.12%(1) for the three months ended June 30, 2022.

Net interest income before provision for credit losses for the three months ended June 30, 2022 was $248.5 million compared with $245.4 million for the same period in 2021, an increase of $3.1 million or 1.3%. On a linked quarter basis, net interest income before provision for credit losses was $248.5 million compared with $239.9 million for the three months ended March 31, 2022, an increase of $8.5 million or 3.6%. The change was primarily due to an increase in the average balances and average rates on investment securities.

The net interest margin on a tax equivalent basis was 2.97% for the three months ended June 30, 2022 compared with 3.11% for the same period in 2021. The change was primarily due to a decrease in loan discount accretion of $12.1 million and a decrease in PPP fees and interest income of $10.4 million, partially offset by an increase in the average balances and average rates on investment securities and 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 2.97% for the three months ended June 30, 2022 compared with 2.88% for the three months ended March 31, 2022. The change was primarily due to higher average balances and average rates on investment securities and lower cash balances due to a reduction in liquidity, partially offset by a decrease in loan discount accretion of $5.1 million.

Noninterest income was $37.6 million for the three months ended June 30, 2022 compared with $35.6 million for the same period in 2021, an increase of $2.0 million or 5.7%. This change was primarily due to an increase in nonsufficient funds fees ("NSF") income, a net gain on the sale or write-down of assets and an increase in trust income, partially offset by a decrease in mortgage income. On a linked quarter basis, noninterest income was $37.6 million compared with $35.1 million for the three months ended March 31, 2022, an increase of $2.5 million or 7.0%. This change was primarily due to increases in credit card, debit card and ATM card income, a net gain on the sale or write-down of assets and other noninterest income.

Noninterest expense was $122.9 million for the three months ended June 30, 2022 compared with $115.2 million for the same period in 2021, an increase of $7.7 million or 6.7%, primarily due to an increase in salaries and benefits and the change in net loss (gain) on sale or write-down of other real estate. On a linked quarter basis, noninterest expense increased $3.0 million or 2.5% to $122.9 million compared with $119.9 million for the three months ended March 31, 2022.

Balance Sheet Information

At June 30, 2022, Prosperity had $37.387 billion in total assets, an increase of $1.287 billion or 3.6%, compared with $36.100 billion at June 30, 2021.

Loans at June 30, 2022 were $18.209 billion, a decrease of $1.043 billion or 5.4%, compared with $19.252 billion at June 30, 2021, primarily due to decreases in Warehouse Purchase Program, PPP and commercial real estate loans, partially offset by increases in 1-4 family residential and construction, land development and other land loans. Linked quarter loans increased $141.3 million or 0.8% (3.1% annualized) from $18.068 billion at March 31, 2022. Excluding Warehouse Purchase Program and PPP loans, loans at June 30, 2022 were $17.044 billion compared to $16.376 billion at June 30, 2021, an increase of $667.4 million or 4.1%. Linked quarter loans, excluding Warehouse Purchase Program and PPP loans, increased $406.9 million or 2.4% (9.8% annualized) from $16.637 billion at March 31, 2022.

As part of its lending activities, Prosperity extends credit to oil and gas production and servicing companies. Oil and gas production loans are loans to companies directly involved in the exploration and/or production of oil and gas. Oil and gas servicing loans are loans to companies that provide services for oil and gas production and exploration. At June 30, 2022, oil and gas loans totaled $430.3 million (net of discount and excluding PPP loans totaling $8.2 million) or 2.4% of total loans, of which $214.0 million were production loans and $216.3 million were servicing loans, compared with total oil and gas loans of $501.8 million (net of discount and excluding PPP loans totaling $92.3 million) or 2.6% of total loans at June 30, 2021, of which $283.1 million were production loans and $218.7 million were servicing loans. In addition, as of June 30, 2022, Prosperity had total unfunded commitments to oil and gas companies of $466.7 million compared with total unfunded commitments to oil and gas companies of $298.4 million as of June 30, 2021. Unfunded commitments to producers include letters of credit issued in lieu of oil well plugging bonds.

Deposits at June 30, 2022 were $29.866 billion, an increase of $755.4 million or 2.6%, compared with $29.110 billion at June 30, 2021. Linked quarter deposits decreased $1.203 billion or 3.9% from $31.068 billion at March 31, 2022, primarily due to a decrease in public fund deposits. Prosperity generally experiences seasonality with its public fund deposits, as public fund customers use the tax dollars they receive in December and January throughout the year, resulting in lower deposit balances in the second and third quarters of the year. On a linked quarter basis, noninterest-bearing deposits increased by $255.5 million.

Asset Quality

Nonperforming assets totaled $22.2 million or 0.07% of quarterly average interest-earning assets at June 30, 2022 compared with $33.7 million or 0.11% of quarterly average interest-earning assets at June 30, 2021 and $27.2 million or 0.08% of quarterly average interest-earning assets at March 31, 2022.

Dividend

Stock Repurchase Program

On January 18, 2022, Prosperity Bancshares announced a stock repurchase program under which up to 5%, or approximately

4.61 million shares, of its outstanding common stock may be acquired over a one-year period expiring on January 18, 2023, at the discretion of management. Prosperity Bancshares repurchased 981,884 shares of its common stock at an average weighted price of $66.90 per share during the three and six months ended June 30, 2022.

COVID-19 Pandemic

The Company continues to monitor the latest developments regarding a novel strain of coronavirus disease ("COVID-19"). Although the restrictions previously imposed on businesses and activities by the states of Texas and Oklahoma remained lifted as of June 30, 2022, it is possible that some restrictions could be re-introduced if the number of cases were to increase due to the emergence of a new variant of COVID-19 or otherwise. The COVID-19 pandemic has resulted in significant economic uncertainties that have had, and could continue to have, an adverse impact on the Company's operating income, financial condition and cash flows. The extent to which the COVID-19 pandemic will impact the Company's operations and financial results during 2022 cannot be reasonably or reliably estimated at this time.

Since the implementation of the Paycheck Protection Program ("PPP") in 2020, the Company has obtained Small Business Administration approvals on approximately 18,700 loans totaling $2.036 billion and, as of June 30, 2022, had an outstanding balance of 237 loans totaling $27.6 million.

In response to the COVID-19 pandemic, the Company provided relief to its loan customers through loan extensions and deferrals beginning in March 2020 to selected borrowers on a case-by-case basis. The Company's troubled debt restructurings do not include loan modifications related to COVID-19. As of June 30, 2022, the Company had no outstanding loans subject to deferral and modification agreements.

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.

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, 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.
