Prosperity Bancshares, Inc.® (NYSE: PB), the parent company of Prosperity Bank® (collectively, "Prosperity"), reported net income for the quarter ended June 30, 2020 of  $130.9 million compared with $82.3 million for the same period in 2019. Net income per diluted common share was $1.41 compared with $1.18 for the same period in 2019.  The second quarter of 2020 includes a tax benefit for net operating losses ("NOLs") of $20.1 million, or $0.22(1) per diluted common share, as a result of the enactment of the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"). The CARES Act permits a five year carryback period for NOLs, which allowed Prosperity to generate an anticipated tax refund and income tax benefit resulting from the tax rate differential between the current statutory tax rate of 21% and the 35% statutory tax rate in prior years during the carryback period.

During the second quarter of 2020, Prosperity incurred merger related charges of $7.5 million, or $0.06⁽¹⁾ per diluted common share. Additionally, loans increased 9.9% during the second quarter 2020 and nonperforming assets remain low at 0.28% of second quarter average interest-earning assets. On November 1, 2019, LegacyTexas Financial Group, Inc. ("LegacyTexas") merged with Prosperity Bancshares and LegacyTexas Bank merged with Prosperity Bank (collectively, the "Merger"). During the second quarter of 2020, Prosperity completed the operational conversion of LegacyTexas Bank.

"We are pleased with our second quarter 2020 results and with completing the operational integration of Legacy on schedule in early June. The team members from Legacy "now Prosperity" have been excellent and we could not have achieved such a smooth integration without their commitment and efforts. I want to thank all of our team members who worked many hours to make this happen," said David Zalman, Prosperity's Senior Chairman and Chief Executive Officer.

"The second quarter 2020 diluted earnings per share of $1.41 includes a $0.22 income tax benefit, a $0.06 charge for merger related expenses and a $0.03 charge for the write down of fixed assets related to the Merger and CRA funds," continued Zalman.

"During the second quarter, we saw a $1.898 billion, or 9.9%, increase in loans, mostly related to loans made under the SBA Paycheck Protection Program (PPP). We approved 11,972 PPP loans for a total of $1.411 billion. These loans were important to our customers, enabling them to remain in business at a time they were either operating at a reduced capacity or temporarily shut down. Deposits increased $2.326 billion, or 9.8%, during the quarter, related to funds from the PPP loans and decreased customer spending," added Zalman.

"We continue to provide relief to our loan customers through loan extensions and deferrals when possible. For the second quarter of 2020, net charge offs were $13.0 million. Of these charge-offs, $12.4 million were related to PCD loans with specific reserves of $28.5 million that we acquired in the Merger. Further, $16.1 million in specific reserves were released to the general reserve in addition to the $10.0 million provision for loan losses for the second quarter," stated Zalman.

"The Blue-Chip Consensus forecast estimates that fourth quarter 2020 GDP will end at (5.6%) compared with fourth quarter 2019, however, they are forecasting a 4.8% GDP for fourth quarter 2021 compared with fourth quarter 2020. They are also forecasting an unemployment rate of 9.4% for the fourth quarter 2020 compared with an unemployment rate of 6.9% for fourth quarter 2021. Based on these estimates, 2021 looks brighter. We are positive about our company's future. While our operating environment and economy is changing frequently, we remain focused on addressing whatever comes our way and taking care of our customers and associates," concluded Zalman.

The net interest margin on a tax equivalent basis was 3.69% for the three months ended June 30, 2020 compared with 3.16% for the same period in 2019.

On a linked quarter basis, noninterest income decreased $8.7 million or 25.3% to $25.7 million compared with $34.4 million for the three months ended March 31, 2020.

Noninterest expense was $134.4 million for the three months ended June 30, 2020 compared with $80.8 million for the same period in 2019, an increase of $53.5 million or 66.3%, primarily due to the Merger and merger related expenses of $7.5 million. On a linked quarter basis, noninterest expense increased $9.6 million or 7.7% to $134.4 million compared with $124.7 million for the three months ended March 31, 2020.

COVID-19 Pandemic

In December 2019, a novel strain of coronavirus disease ("COVID-19") was first reported in Wuhan, Hubei Province, China. On March 11, 2020, the World Health Organization declared COVID-19 a pandemic. On March 13, the U.S. President announced a national emergency relating to the pandemic and has since been extended. On July 10, the Texas governor extended the proclamation certifying that COVID-19 poses an imminent threat of disaster in the state and declaring a state of disaster for all counties in Texas. Prosperity Bank (the "Bank") is considered an essential business and is closely monitoring the latest developments regarding COVID-19. The health and safety of our associates, customers, and communities are of utmost importance, and the Bank remains committed to providing uninterrupted service. Additionally, the Bank has continuity plans in place to ensure critical operations are able to continue without disruption. The COVID-19 pandemic has resulted in significant economic uncertainties that could negatively impact Prosperity's operating income, financial condition and cash flows.

In response to the COVID-19 pandemic, the CARES Act was signed into law on March 27, 2020 by the President of the United States. The CARES Act provides assistance for American workers, families and small businesses. The Paycheck Protection Program ("PPP"), established by the CARES Act, is implemented by the Small Business Administration ("SBA") with support from the Department of the Treasury. This program provides small businesses with funds to pay payroll costs including benefits. Funds can also be used to pay interest on mortgages, rent, and utilities. On June 5, 2020, the President signed the Paycheck Protection Program Flexibility Act of 2020 ("PPP Flexibility Act"), which modified the covered expense period from eight weeks to 24 weeks, extended the maturity date of the loans out five years and gave greater flexibility to employers having difficulty hiring workers. PPP loans originated prior to June 5, 2020, have a two year term and earn interest at 1%. PPP loans originated on and after June 5, 2020, have a five year term. On July 4, 2020, the President amended the CARES Act to extend the PPP application period for an additional five weeks. The loans are eligible for early forgiveness by the SBA as provided by the CARES Act and the PPP Flexibility Act and related regulations and guidance. Additionally, the Bank is entitled to a per loan processing fee based on a tiered schedule ranging from 5% to 1% of the loan balance. As of July 7, 2020, the Company has obtained SBA approvals on approximately 11,972 loans totaling $1.411 billion. The Company has also provided relief to its loan customers through loan extensions and deferrals.

Merger with LegacyTexas Financial Group, Inc.

On November 1, 2019, Prosperity completed the merger with LegacyTexas and its wholly-owned subsidiary LegacyTexas Bank headquartered in Plano, Texas. LegacyTexas Bank operated 42 locations in 19 North Texas cities in and around the Dallas-Fort Worth area. 

Pursuant to the terms of the merger agreement, Prosperity issued 26,228,148 shares of Prosperity common stock with a closing price of $69.02 per share plus $318.0 million in cash, made up of $308.6 million in cash and $9.4 million in cash for taxes withheld, for all outstanding shares of LegacyTexas. This resulted in goodwill of $1.331 billion as of June 30, 2020, which was subject to subsequent fair value adjustments. During the second quarter of 2020, Prosperity completed the operational conversion of LegacyTexas Bank.

Non-GAAP Financial Measures

Prosperity's management uses certain non-GAAP financial measures to evaluate its performance. Specifically, Prosperity reviews diluted earnings per share excluding merger related expenses, net of tax, and NOL carryback; return on average assets excluding merger related expenses, net of tax, and NOL carryback; return on average common equity excluding merger related expenses, net of tax, and NOL carryback; tangible book value per share, return on average tangible common equity, the tangible equity to tangible assets ratio and return on average tangible common equity, all excluding merger related expenses, net of tax, and NOL carryback; allowance for credit losses 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 and merger related expenses, 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 that 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 diluted earnings per share excluding merger related expenses, net of tax, and NOL carryback; return on average assets excluding merger related expenses, net of tax, and NOL carryback; return on average common equity excluding merger related expenses, net of tax, and NOL carryback; tangible book value per share, return on average tangible common equity, the tangible equity to tangible assets ratio and return on average tangible common equity, all excluding merger related expenses, net of tax, and NOL carryback; allowance for credit losses 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 and merger related expenses, 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 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.
