RBB Bancorp (NASDAQ:RBB) and its subsidiaries, Royal Business Bank ("the Bank") and RBB Asset Management Company ("RAM"), collectively referred to herein as "the Company," announced financial results for the quarter ended March 31, 2023.

The Company reported net income of $11.0 million, or $0.58 diluted earnings per share, for the quarter ended March 31, 2023, compared to net income of $17.6 million, or $0.92 diluted earnings per share, and $14.6 million, or $0.74 diluted earnings per share, for the quarter ended December 31, 2022 and March 31, 2022, respectively.

"Fundamentally our first quarter results reflected a solid start to 2023, despite the challenges the industry faced in March," said David Morris, President and CEO of RBB Bancorp. "Net income was impacted by increased legal expenses and other professional expenses, but we expect these expenses to normalize in future quarters. Thanks to the loyalty of our customers, we achieved a 5.8% increase in deposits in the first quarter and we are cautiously optimistic that the rapid increase in our cost of deposits and cost of funds that we have experienced over the past year will moderate in coming quarters. Our liquidity remains strong, and we are well positioned to service our existing customers. We expect our loan to deposit ratio to decrease in 2023 as we restructure our balance sheet in response to the ongoing market volatility."

"Management and the Board continue to focus on rigorously improving internal processes and taking actions necessary to maximize long-term shareholder value," said Dr. James Kao, Chairman of the Company, "We are pleased to welcome Mr. Scott Polakoff and Mr. Robert Franko to the Board of Directors of RBB Bancorp and believe they possess the skills and experience to enhance our governance and assist us in positioning the Company to take advantage of future opportunities to expand our business and grow our franchise." Mr. Polakoff is a former Regional Director of the Federal Deposit Insurance Corporation for the Chicago Region and Mr. Franko is a long-time commercial banker, most recently the President and CEO of First Choice Bank.

Net Interest Income and Net Interest Margin

Net interest income, before provision for credit losses, was $34.1 million for the first quarter of 2023, compared to $39.0 million for the fourth quarter of 2022. The $4.9 million decrease was primarily attributable to an increase in interest expense on time deposits. For the first quarter of 2023, average time deposits increased $327.1 million and the interest rate paid on time deposits increased 96 basis points, from 2.29% to 3.25%, from the fourth quarter of 2022.

Compared to the first quarter of 2022, net interest income, before provision for credit losses, decreased $390,000 from $34.5 million. The decrease was primarily attributable to an increase in average interest-bearing deposits of $206.7 million and a 231 basis points increase in the interest rate paid on interest-bearing deposits, partially offset by an increase in average loans of $359.2 million and a 92 basis points increase in the yield earned on loans.

Net interest margin was 3.70% for the first quarter of 2023, a decrease of 56 basis points from 4.26% in the fourth quarter of 2022 due primarily to an 82 basis point increase in the average cost on interest-bearing deposits from 1.93% in the fourth quarter of 2022 to 2.75% in the first quarter of 2023. Cost of interest-bearing deposits increased due to increasing market rates and peer bank deposit competition.

Noninterest Income

Noninterest income was $2.4 million for the first quarter of 2023, an increase of $10,000 from $2.4 million in the fourth quarter of 2022. The increase was primarily driven by a $150,000 increase in loan servicing fees due to loan prepayments slowing down in 2023 and a $34,000 increase in service charges, partially offset by an $85,000 decrease in recoveries on purchased loans and a $83,000 decrease in gain on sale of loans during the quarter.

During the first quarter of 2023, loan sale volume and gain on loan sales decreased compared to prior quarter. The Company sold $836,000 in Federal National Mortgage Association ("Fannie Mae") qualified mortgage loans for a net gain of $19,000 during the first quarter of 2023 compared to $2.8 million in Fannie Mae qualified mortgage loans sold for a net gain of $69,000 during the fourth quarter of 2022. The Company sold $127,000 in Small Business Association ("SBA") loans during the first quarter of 2023 for a net gain of $10,000, compared to $834,000 SBA loans sold for a net gain of $43,000 during the fourth quarter of 2022.

Noninterest income decreased by $405,000 from $2.9 million in the first quarter of 2022. The decrease was primarily attributable to a $1.1 million decrease in gain on sale of loans due to interest rate hikes that caused decreases in both loans held for sale and gains on loans sold.

Noninterest Expense

Noninterest expense for the first quarter of 2023 was $18.9 million, compared to $14.2 million for the fourth quarter of 2022. The $4.8 million increase was primarily attributable to a $2.9 million increase in salaries and employee benefits expenses and a $2.0 million increase in legal and other professional fees. The increase in salaries and employee benefits expenses was due to the normalization of those benefits following fourth quarter reversals which reduced those expenses.

Income Taxes

The effective tax rate was 29.4% for the first quarter of 2023, 30.5% for the fourth quarter of 2022, and 30.4% for the first quarter of 2022.

Balance sheet Management

Management expects to reduce the size of the loan portfolio in the next few quarters by slowing the pace of loan originations and focusing on supporting core relationships. Management is targeting a reduction in the loan to deposit ratio to below 100% by June 30, 2023 and to below 95% by the end of 2023 and is proactively offering various alternatives, including IntraFi Cash Service ("ICS") and CDARS, to clients with deposit balances that exceed $250,000 to reduce the level of uninsured deposits.

Loan and Securities Portfolio

Loans held for investment, net of deferred fees and discounts, totaled $3.34 billion as of March 31, 2023, an increase of $6.0 million from December 31, 2022, and an increase of $335.9 million from March 31, 2022. The increase from December 31, 2022 was primarily due to a $75.9 million increase in single-family residential mortgage loans, partially offset by a $45.2 million decrease in commercial and industrial loans and a $23.9 million decrease in commercial real estate loans. The increase from March 31, 2022 was primarily due to a $475.4 million increase in single-family residential mortgages and a $70.2 million increase in commercial real estate loans, offset by a $124.8 million decrease in commercial and industrial loans and a $65.6 million decrease in construction and land development loans.

During the first quarter of 2023, single-family residential mortgage production was $108.7 million while net payoffs and paydowns were $32.0 million. During the fourth quarter of 2022, single-family residential mortgage production was $130.8 million while payoffs and paydowns were $21.4 million.

There were no mortgage loans held for sale as of March 31, 2023 and December 31, 2022 and $3.6 million as of March 31, 2022. The Company originated $836,000 in Fannie Mae mortgage loans for sale during the first quarter of 2023, compared with $889,000 during the fourth quarter of 2022.

In the first quarter of 2023, SBA loan production was $3.0 million and total SBA loan sales were $127,000 compared to SBA loan production of $10.2 million and total SBA loan sales of $834,000 in the fourth quarter of 2022.

As of March 31, 2023, the Bank's total available-for-sale securities amounted to $293.4 million, including available-for-sale securities maturing in over 12 months of $235.9 million. As of March 31, 2023 the Bank recorded gross unrealized losses of $28.7 million on its available-for-sale securities compared to gross unrealized losses of $31.2 million as of December 31, 2022 with respect to its available-for-sale securities.

Liquidity and Deposits

Total deposits were $3.2 billion as of March 31, 2023, which reflected an increase of $173.4 million or 5.8% compared to December 31, 2022. As of March 31, 2023, the Company had $230.7 million in cash on the balance sheet, which is an increase of $147.2 million or 176% from December 31, 2022. In addition, the Company had $818.4 million in Federal Home Loan Bank borrowing availability, Fed fund lines of $92.0 million, $11.2 million in available funds from the FRB Discount window and $293.3 million in available for sale securities that were unpledged. The Company has $149.1 million loans qualified to be pledged to the FRB. The total of these available sources represents $1.6 billion or 146% of total uninsured deposit or 169% of adjusted uninsured deposit, which excludes ICS and CDARS program deposits and uninsured deposits affiliated with directors and officers of the Company.

Total adjusted uninsured deposits of $945.4 million represented approximately 30% of total deposits as of March 31, 2023. Uninsured deposits affiliated with directors and officers of the Company amounted to $29.1 million. Since mid-March, we have been diligently working with our larger deposit clients to enroll them in the ICS and CDARS program to ensure that all of their deposits are FDIC insured. ICS and CDARS program deposits amounted $116.2 million at March 31, 2023.

Credit Quality

Nonperforming assets totaled $27.0 million, or 0.66% of total assets at March 31, 2023, compared to $24.1 million, or 0.61% of total assets at December 31, 2022. The $2.9 million increase in nonperforming assets was due to the increase in single-family residential loans in the amount of $4.7 million, partially offset by single-family residential loan payoffs or paydowns of $1.8 million.

Our 30-89 day delinquent loans, excluding non-accrual loans, decreased $961,000 to $14.3 million as of March 31, 2023 compared to $15.2 million as of December 31, 2022.

Total net charge-offs were $157,000 for the first quarter of 2023, as compared to net charge-offs of $85,000 in the prior quarter and net recoveries of $14,000 in the same quarter last year.

The allowance for credit losses totaled $43.1 million, or 1.29% of loans held for investment at March 31, 2023, compared with $41.1 million, or 1.23%, of loans held for investment at December 31, 2022.

Non-GAAP Financial Measures

Tangible Book Value Reconciliations

The tangible book value per share is a non-GAAP disclosure. Management measures the tangible book value per share to assess the Company's capital strength and business performance and believes these are helpful to investors as additional tool for further understanding our performance. The following is a reconciliation of tangible book value to the Company shareholders' equity computed in accordance with GAAP, as well as a calculation of tangible book value per share as of March 31, 2023, December 31, 2022, and March 31, 2022.

Return on Average Tangible Common Equity

Management measures return on average tangible common equity ("ROATCE") to assess the Company's capital strength and business performance and believes these are helpful to investors as an additional tool for further understanding our performance. Tangible equity excludes goodwill and other intangible assets (excluding mortgage servicing rights), and is reviewed by banking and financial institution regulators when assessing a financial institution's capital adequacy. This non-GAAP financial measure should not be considered a substitute for operating results determined in accordance with GAAP and may not be comparable to other similarly titled measures used by other companies. The following table reconciles return on average tangible common equity to its most comparable GAAP measure:
