“Royal Business Bank’s excellent fourth quarter results contributed to a record year of growth and performance in 2021,” said Alan Thian, President and CEO of RBB Bancorp. “Our strategy of expansion has proven to be an effective driver of shareholder value by enhancing earnings, accelerating loan growth, and improving our deposit franchise. Our recent expansion into the vibrant Hawaiian market and our announced acquisition of Gateway Bank in the San Francisco Bay area will provide us with additional opportunities to bring our relationship-banking model to new markets.”

"2021 was a tremendous year for the Bank," said Dr. James Kao, Chairman of RBB Bancorp. “Not only did the Bank achieve record results and growth, but it was also recognized multiple times for the work it does to serve the financial needs of the communities in which it operates. Two members of the RBB team, Alan Thian and Simon Pang, were appointed to national commissions to advise on community development and the Bank was the awarded a CDFI grant from the US Treasury to support distressed and underserved communities.”

Key Performance Ratios

Net income of $15.7 million for the fourth quarter of 2021 produced an annualized return on average assets ("ROA") of 1.52%, an annualized return on average tangible common shareholders' equity ("ROTCE") of 15.98%, and an annualized return on average shareholders' equity ("ROE") of 13.45%. This compares to an annualized return on average assets of 1.54%, an annualized return on average tangible common shareholders' equity of 16.17%, and an annualized return on average shareholders' equity of 13.52% for the third quarter of 2021. The efficiency ratio for the fourth quarter of 2021 was 36.56%, compared to 38.87% for the prior quarter.

Net Interest Income and Net Interest Margin

Net interest income, before provision for loan losses, was $33.2 million for the fourth quarter of 2021, compared to $31.6 million for the third quarter of 2021. The $1.6 million increase was primarily attributable to higher interest income due to a $135.9 million increase in average earning assets and a $51.1 million decrease in average interest-bearing liabilities. Accretion of purchase discounts from prior acquisitions contributed $192,000 to net interest income in the fourth quarter of 2021, compared to $289,000 in the third quarter of 2021.

Compared to the fourth quarter of 2020, net interest income, before provision for loan losses, increased $4.3 million from $28.9 million. The increase was primarily attributable to a $713.3 million increase in average earning assets, partially offset by a $137.3 million increase in average interest-bearing liabilities. The increases in average earning assets and total deposits were primarily due to increased loan and deposit originations.

Net interest margin was 3.43% for the fourth quarter of 2021, an increase of 5 basis points from 3.38% in the third quarter of 2021. Loan discount accretion contributed 2 basis points to the net interest margin in the fourth quarter of 2021, compared to 3 basis points in the third quarter of 2021.

Noninterest Income

Noninterest income was $3.2 million for the fourth quarter of 2021, a decrease of $2.4 million from $5.5 million in the third quarter of 2021. The decrease was primarily driven by a one-time $1.8 million CDFI grant received during the third quarter and a $455,000 decrease in gain on derivatives, partially offset by a $196,000 increase in loan servicing fees during the quarter.

The Company sold $37.7 million in FNMA qualified mortgage loans for a net gain of $1.4 million and sold no non-qualified mortgage loans during the fourth quarter of 2021. This compared to $36.6 million in FNMA qualified mortgage loans sold for a net gain of $1.2 million and no non-qualified mortgage loans during the third quarter of 2021. The Company sold $5.5 million in SBA loans during the fourth quarter of 2021 for a net gain of $436,000, compared to $5.9 million SBA loans sold for a net gain of $553,000 during the third quarter of 2021.

Compared to the fourth quarter of 2020, noninterest income decreased by $1.3 million from $4.5 million. The decrease was primarily attributable to a decrease of $657,000 in gain on sale of loans and a decrease of $378,000 in unrealized gain (loss) on equity investment.

Noninterest Expense

Noninterest expense for the fourth quarter of 2021 was $13.3 million, compared to $14.4 million for the third quarter of 2021. The $1.1 million decrease was primarily attributable to a $2.0 million decrease in salaries and benefit expenses, partially offset by $940,000 increase in legal and professional expense. The fourth quarter increase in legal and professional expenses were due, in part, to expenses related to the acquisition of the branch in Honolulu, Hawaii and the announced acquisition of Gateway Bank.

Noninterest expense decreased from $14.5 million in the fourth quarter of 2020. The $1.2 million decrease was primarily due to a $1.3 million decrease in salaries and benefits expenses, $275,000 decrease in occupancy and equipment expenses and a $174,000 decrease in data processing expenses, partially offset by an $892,000 increase in legal and professional expenses.

Income Taxes

The effective tax rate was 30.0% for the fourth quarter of 2021, 28.5% for the third quarter of 2021, and 29.9% for the fourth quarter of 2020. The Company recognized a tax expense (benefit) from stock option exercises of ($215,000), ($534,000) and zero for the fourth quarter of 2021, the third quarter of 2021, and the fourth quarter of 2020, respectively.

Loan Portfolio

Loans held for investment, net of deferred fees and discounts, totaled $2.93 billion as of December 31, 2021, an increase of $91.0 million from September 30, 2021, and an increase of $224.6 million from December 31, 2020. The increase from the prior quarter was primarily due to a $42.4 million increase in commercial real estate loans, $31.4 million increase in construction & land development loans and a $29.8 million increase in single-family residential mortgages. The increase from December 31, 2020 was primarily due to a $244.4 million increase in commercial real estate loans, $116.4 million increase in construction & land development loans, partially offset by a $119.8 million decrease in single-family residential mortgages.

During the fourth quarter of 2021, single-family residential mortgage production was $137.7 million while payoffs and paydowns were $79.5 million. During the third quarter of 2021, single-family residential mortgage production was $112.0 million while payoffs and paydowns were $79.0 million.

During the fourth quarter of 2021, noninterest-bearing deposits increased by $466.7 million, interest-bearing non-maturity deposits decreased by $3.9 million, and time deposits decreased by $45.1 million. Noninterest-bearing deposits increased due to expanding relationships with a number of our commercial clients. As of December 31, 2021, time deposits included $2.4 million in brokered CDs, as compared to $2.4 million as of September 30, 2021 and $17.4 million as of December 31, 2020. Compared to December 31, 2020, total deposits increased by $750.4 million, which included a $674.3 million increase in noninterest bearing deposits and a $76.1 million increase in interest-bearing deposits.

Asset Quality

Nonperforming assets totaled $21.0 million, or 0.50% of total assets at December 31, 2021, compared to $14.5 million, or 0.38% of total assets at September 30, 2021. The $6.5 million increase in non-performing assets was due to the addition of three commercial real estate loans in the amount of $3.5 million, one SFR loan for $156,000 and three commercial and industrial loans for $3.7 million, less paydowns and payoffs on other non-performing loans. Nonperforming assets consist of other real estate owned, loans modified under troubled debt restructurings (“TDR”), non-accrual loans, and loans past due 90 days or more and still accruing interest.

In the fourth quarter of 2021, there were $46,000 in net recoveries, compared to net charge-offs of $317,000 in the third quarter.

The Company recorded a provision for credit losses of $635,000 for the fourth quarter of 2021, a decrease from $1.2 million in the prior quarter, primarily attributable to a reduction of the COVID-19 special reserve in the allowance for loan losses.

The allowance for loan losses totaled $32.9 million, or 1.12% of loans held for investment at December 31, 2021, compared with $32.2 million, or 1.13%, of total loans at September 30, 2021.

As of December 31, 2021, borrowers representing 69 loans totaling $11.8 million, or 0.40% of the Company’s total loan portfolio, have funded under the SBA’s Paycheck Protection Program due to the COVID-19 pandemic. Presently none of our SBA customers are on a payment deferral plan due to the COVID-19 pandemic.
