Exhibit 99.1
 
BANKUNITED, INC. REPORTS FIRST QUARTER 2021 RESULTS
 
Miami Lakes, Fla. — April 22, 2021 — BankUnited, Inc. (the “Company”) (NYSE: BKU) today announced financial results for the quarter ended March 31, 2021.
“This quarter, non-interest DDA grew by almost $1 billion, our net interest margin expanded, and we released some of the reserves we put up last year. This quarter also marks the culmination of our 2 year cloud journey, and the release of our new mobile banking platform." said Rajinder Singh, Chairman, President and Chief Executive Officer.
For the quarter ended March 31, 2021, the Company reported net income of $98.8 million, or $1.06 per diluted share, compared to a net loss of $(31.0) million, or $(0.33) per diluted share, for the quarter ended March 31, 2020. On an annualized basis, earnings for the quarter ended March 31, 2021 generated a return on average stockholders' equity of 13.2% and a return on average assets of 1.14%.
Financial Highlights
Net interest income increased by $2.9 million compared to the immediately preceding quarter ended December 31, 2020 and by $15.7 million compared to the quarter ended March 31, 2020. The net interest margin, calculated on a tax-equivalent basis, improved to 2.39% for the quarter ended March 31, 2021 from 2.33% for the immediately preceding quarter and 2.35% for the quarter ended March 31, 2020.
The average cost of total deposits continued to decline, dropping by 0.10% to 0.33% for the quarter ended March 31, 2021 from 0.43% for the immediately preceding quarter ended December 31, 2020, and 1.36% for the quarter ended March 31, 2020. On a spot basis, the average annual percentage yield ("APY") on total deposits declined to 0.27% at March 31, 2021 from 0.36% at December 31, 2020 and 1.35% at March 31, 2020.
For the quarter ended March 31, 2021, the Company recorded a recovery of the provision for credit losses of $(28.0) million compared to a recovery of $(1.6) million for the immediately preceding quarter ended December 31, 2020 and a provision for credit losses of $125.4 million for the quarter ended March 31, 2020. The most significant factor leading to the recovery of credit losses for the quarter ended March 31, 2021 was an improving economic forecast. In contrast, the provision for credit losses for the quarter ended March 31, 2020 was driven primarily by a deteriorating economic forecast resulting from the onset of the COVID-19 pandemic.
Pre-tax, pre-provision net revenue ("PPNR") was $103.3 million for the quarter ended March 31, 2021 compared to $105.3 million for the immediately preceding quarter ended December 31, 2020 and $85.0 million for the quarter ended March 31, 2020.
Non-interest bearing demand deposits grew by $957 million during the quarter ended March 31, 2021. Total deposits grew by $236 million as higher cost time deposits continued to runoff, declining by $1.0 billion for the quarter ended March 31, 2021. Average non-interest bearing demand deposits grew by $338 million for the quarter ended March 31, 2021 compared to the immediately preceding quarter ended December 31, 2020 and by $3.1 billion compared to the quarter ended March 31, 2020. At March 31, 2021, non-interest bearing demand deposits represented 29% of total deposits, compared to 25% of total deposits at December 31, 2020.
Total loans and operating lease equipment declined by $487 million for the quarter ended March 31, 2020.
Loans on deferral totaled $126 million or less than 1% of total loans at March 31, 2021. Loans modified under the CARES Act totaled $636 million at March 31, 2021. In the aggregate, this represents $762 million or 3% of the total loan portfolio at March 31, 2021.
Non-performing assets totaled $236 million or 0.67% of total assets at March 31, 2020, a decline from $248 million or 0.71% of total assets at December 31, 2020.

Growth in residential and other consumer loans for the quarter was attributable to GNMA early buyout loans. At March 31, 2021 and December 31, 2020, the residential portfolio included $1.7 billion and $1.4 billion, respectively, of GNMA early buyout loans. Residential activity for the quarter included purchases of approximately $578 million in GNMA early buyout loans, offset by approximately $237 million in re-poolings and paydowns. Residential and other consumer loans, excluding GNMA early buyout loans, declined by approximately $107 million.
In the aggregate, commercial loans declined by $739 million for the quarter ended March 31, 2021 as the environment remained challenging for new production, line utilization was below historical levels and accelerated prepayment activity continued. MWL line utilization declined seasonally to 55% at March 31, 2021 compared to 62% at December 31, 2020.
We originated $265 million of PPP loans under the Second Draw Program during the quarter ended March 31, 2021. Loans originated under the First Draw Program totaling $138 million were fully or partially forgiven during the quarter.

The ACL at March 31, 2021 represents management's estimate of lifetime expected credit losses from the loan portfolio given our assessment of historical data, current conditions and a reasonable and supportable economic forecast as of the balance sheet date. The estimate was informed by Moody's economic scenarios published in March 2021, economic information provided by additional sources, data reflecting the impact of recent events on individual borrowers and other relevant information. The

decline in the ACL and in ACL coverage ratios from December 31, 2020 to March 31, 2021 related primarily to to the recovery of credit losses recorded during the quarter. The decline in the ACL was primarily related to the pass rated portion of the portfolio.
For the quarter ended March 31, 2021, the Company recorded a recovery of credit losses of $(28.0) million, which included a recovery of $(26.3) million related to funded loans as well as immaterial amounts related to unfunded loan commitments, accrued interest receivable and an AFS debt security. The recovery of provision for credit losses was largely driven by improvements in forecasted economic conditions.

Net interest income
Net interest income for the quarter ended March 31, 2021 was $196.2 million compared to $193.4 million for the immediately preceding quarter ended December 31, 2020 and $180.6 million for the quarter ended March 31, 2020.
Interest income decreased by $5.7 million for the quarter ended March 31, 2021 compared to the immediately preceding quarter, and by $48.7 million compared to the quarter ended March 31, 2020. Interest expense decreased by $8.6 million compared to the immediately preceding quarter and by $64.4 million compared to the quarter ended March 31, 2020. Decreases in interest income resulted from declines in market interest rates including the impact of repayment of assets originated in a higher rate environment and, with respect to comparison to the immediately preceding quarter, declines in average loans and investment securities. Declines in interest expense reflected decreases in market interest rates, the impact of our strategy focused on lowering the cost of deposits and improving the deposit mix and declines in average interest bearing liabilities.
The Company’s net interest margin, calculated on a tax-equivalent basis, increased by 0.06% to 2.39% for the quarter ended March 31, 2021, from 2.33% for the immediately preceding quarter ended December 31, 2020. The decline in the average rate paid on interest bearing liabilities, particularly deposits, exceeded the decline in the average yield on interest earning assets. Offsetting factors contributing to the increase in the net interest margin for the quarter ended March 31, 2021 compared to the immediately preceding quarter ended December 31, 2020 included:
The average rate paid on interest bearing deposits decreased to 0.45% for the quarter ended March 31, 2021, from 0.58% for the quarter ended December 31, 2020. This decline reflected continued initiatives taken to lower rates paid on deposits,including the re-pricing of term deposits.
The tax-equivalent yield on investment securities decreased to 1.73% for the quarter ended March 31, 2021 from 1.82% for the quarter ended December 31, 2020. This decrease resulted from the impact of purchases of lower-yielding securities, prepayments of higher yielding mortgage-backed securities and decreases in coupon interest rates on existing floating rate assets.
The tax-equivalent yield on loans increased to 3.58% for the quarter ended March 31, 2021, from 3.55% for the quarter ended December 31, 2020. Accelerated amortization of origination fees on PPP loans that were partially or fully forgiven during the quarter impacted the yield on loans by approximately 0.06%.
The average rate paid on FHLB and PPPLF borrowings increased to 2.32% for the quarter ended March 31, 2021, from 2.07% for the quarter ended December 31, 2020, reflecting the maturity of short-term, lower rate FHLB advances and the payoff of all PPPLF borrowings during the fourth quarter of 2020.
The increase in average non-interest bearing demand deposits as a percentage of average total deposits also positively impacted the cost of total deposits and the net interest margin.

Non-interest income
Non-interest income totaled $30.3 million for the quarter ended March 31, 2021 compared to $35.3 million for the immediately preceding quarter ended December 31, 2020 and $23.3 million for the quarter ended March 31, 2020. These fluctuations in non-interest income were primarily attributable to gain (loss) on investment securities, net which totaled $2.4 million, $7.2 million and $(3.5) million for the quarters ended March 31, 2021, December 31, 2020 and March 31, 2020, respectively. Increases in "other non-interest income" related primarily to increased revenue from our customer derivative program.
Non-interest expense
Non-interest expense totaled $123.2 million for the quarter ended March 31, 2021 compared to $123.3 million for the immediately preceding quarter ended December 31, 2020 and $118.9 million for the quarter ended March 31, 2020. Significant factors contributing to the increase in non-interest expense for the quarter ended March 31, 2021 compared to the quarter ended March 31, 2020 included:
Technology and telecommunications expense increased by $3.1 million reflecting investments in digital and data analytics capabilities and in the infrastructure to support cloud migration.
Deposit insurance expense increased by $3.0 million reflecting an increase in the assessment rate.

Non-GAAP Financial Measures
PPNR is a non-GAAP financial measure. Management believes this measure is relevant to understanding the performance of the Company attributable to elements other than the provision for credit losses and the ability of the Company to generate earnings sufficient to cover estimated credit losses, particularly in view of the volatility of the provision for credit losses resulting from the COVID-19 pandemic. This measure also provides a meaningful basis for comparison to other financial institutions since it is commonly employed and is a measure frequently cited by investors and analysts. The following table reconciles the non-GAAP financial measurement of PPNR to the comparable GAAP financial measurement of income (loss) before income taxes for the three months ended March 31, 2021 and 2020 and the three months ended December 31, 2020 (in thousands):
