•Adjusted net income of $4.8 million, or $0.53 adjusted diluted earnings per share, when excluding (i) net pre-tax costs of $3.0 million incurred as a result of the previously announced exit of the Bank’s consumer mortgage operations and (ii) the aforementioned $4.7 million partial charge-off of the C&I participation loan

•Net interest margin of 1.76% and fully-taxable equivalent net interest margin of 1.89%, compared to 2.09% and 2.22%, respectively, for the fourth quarter of 2022

“Our active management of liquidity, capital and revenue streams in preparation for a dynamic economic environment positioned us to effectively withstand the recent challenges to the banking system,” said David Becker, Chairman and Chief Executive Officer. “Early in the first quarter, we focused on growing deposits and building liquidity, which we successfully accomplished despite intense competition amid the overall decline in system-wide deposits. While we experienced a modest decline in deposits from mid-March through quarter-end, balances have rebounded and are up $135 million thus far in April.

“We remain focused on our strategies to bolster the resilience of our balance sheet and our revenue channels. We continue to improve the composition of the loan portfolio towards a more favorable mix of variable rate and higher yielding loans. New origination yields were up significantly during the quarter, positioning us to achieve stronger earnings and profitability once deposit costs stabilize. In addition, our SBA lending team generated a very strong quarter with gain on sale revenue up over 40% compared to the fourth quarter.”

Mr. Becker concluded, “Despite an issue late in the quarter on one commercial participation loan, our exposure to similar-type loans is very limited and all others are performing well. Our overall asset quality remains solid, and our capital levels are strong.”

Net Interest Income and Net Interest Margin

Net interest income for the first quarter of 2023 was $19.6 million, compared to $21.7 million for the fourth quarter of 2022, and $25.8 million for the first quarter of 2022. On a fully-taxable equivalent basis, net interest income for the first quarter of 2023 was $21.0 million, compared to $23.1 million for the fourth quarter of 2022, and $27.1 million for the first quarter of 2022.

Total interest income for the first quarter of 2023 was $52.0 million, an increase of 13.9% compared to the fourth quarter of 2022, and an increase of 44.4% compared to the first quarter of 2022. On a fully-taxable equivalent basis, total interest income for the first quarter of 2023 was $53.4 million, an increase of 13.5% compared to the fourth quarter of 2022, and an increase of 43.0% compared to the first quarter of 2022. The increase from the linked quarter was due primarily to growth in interest income earned on loans, other earning assets and securities. The yield on average interest-earning assets for the first quarter of 2023 increased to 4.69% from 4.40% for the fourth quarter of 2022 due primarily to a 24 basis point (“bp”) increase in the average loan yield, a 94 bp increase in the yield earned on other earning assets and a 36 bp increase in the yield earned on securities. Compared to the linked quarter, average loan balances increased $191.9 million, or 5.7%, while the average balance of other earning assets increased $181.4 million, or 121.0%, and the average balance of securities increased $6.7 million, or 1.2%.

Interest income earned on commercial loans was higher due to increased average balances and the positive impact of higher rates in the variable rate SBA, construction and investor commercial real estate portfolios, as well as strong growth and higher new origination yields in the franchise finance portfolio. This was partially offset by lower average balances and prepayment fees in the healthcare finance portfolio, as well as lower prepayment fees in the single tenant lease financing portfolio.

In the consumer portfolio, interest income was up due to higher new origination yields, increases in the average balance of residential mortgage, trailers and recreational vehicles portfolios, and higher rates in the variable rate home equity portfolio.

The yield on funded portfolio originations was 7.76% in the first quarter, an increase of 161 bps compared to the fourth quarter of 2022 and an increase of 297 basis points compared to the first quarter of 2022. Because of the fixed-rate nature of certain larger portfolios, there is a lagging impact of origination yields on the portfolio, which are expected to increase over time.

Interest earned on cash and other interest-earning balances increased $2.4 million, or 171.6%, during the quarter due to the impact of higher short-term interest rates on cash balances as well as a $181.4 million increase, or 152.5%, in average cash balances. Furthermore, interest income earned on securities increased $0.5 million, or 12.3%, during the first quarter of 2023 as the yield on the portfolio increased 36 bps to 3.05% driven primarily by variable rate securities resetting higher, slower prepayment speeds and an increase in the average balance of the portfolio.

Total interest expense for the first quarter was $32.5 million, an increase of $8.5 million, or 35.2%, compared to the linked quarter, due to increases in both market interest rates and average interest-bearing deposit balances throughout the quarter. Interest expense related to interest-bearing deposits increased $8.5 million, or 45.0%, driven primarily by higher costs on CD and brokered deposits and money market accounts. Average CD balances increased $261.4 million, or 32.9%, while the cost of funds increased 108 bps, as the Company took advantage of strong consumer and small business demand during the quarter and pulled forward origination activity planned for later in the year. The average balance of brokered deposits increased $165.1 million, or 38.6%, driven by a full quarter’s impact of brokered CD issuances in late 2022, and the cost of funds increased 71 bps. Additionally, while average money market balances decreased $64.0 million, or 4.4%, during the quarter, the cost of these deposits increased 73 bps due to the impact of continued Federal Reserve rate increases.

The average balance of BaaS – brokered deposits increased by $10.2 million, reaching $25.7 million by quarter-end. In total, BaaS deposits were $82.4 million as of March 31, 2023 as Fintech programs were onboarded and existing programs grew during the quarter.

Net interest margin (“NIM”) was 1.76% for the first quarter of 2023, down from 2.09% for the fourth quarter of 2022 and 2.56% for the first quarter of 2022. Fully-taxable equivalent NIM (“FTE NIM”) was 1.89% for the first quarter of 2023, down from 2.22% for the fourth quarter of 2022 and 2.69% for the first quarter of 2022. The decreases in NIM and FTE NIM compared to the linked quarter were driven primarily by the effect of higher interest-bearing deposit costs, partially offset by higher yields on loans, other earning assets and securities.

Noninterest Income

Noninterest income for the first quarter of 2023 was $5.4 million, down $0.4 million, or 6.2%, from the fourth quarter of 2022, and down $1.4 million, or 20.1%, from the first quarter of 2022. Gain on sale of loans totaled $4.1 million for the first quarter of 2023, up $1.2 million, or 41.9%, from the linked quarter. Gain on sale revenue in the quarter consisted entirely of gain on the sales of U.S. Small Business Administration (“SBA”) 7(a) guaranteed loans, which increased due to a higher volume of loan sales, as well as higher net premiums. Other income totaled $0.4 million for the first quarter of 2023, down $1.2 million compared to the linked quarter due to distributions received on certain Small Business Investment Company and venture capital fund investments in the fourth quarter. Mortgage

banking revenue totaled only $0.1 million for the first quarter as the Company immediately began winding down its existing pipeline following its announced exit from the consumer mortgage business in January 2023.

Noninterest Expense

Noninterest expense for the first quarter of 2023 was $21.0 million, up $2.4 million, or 13.2%, from the fourth quarter of 2022 and up $2.2 million, or 11.6%, from the first quarter of 2022. Excluding $3.1 million of mortgage operations and exit costs, adjusted noninterest expense totaled $17.9 million for the first quarter, declining $0.6 million, or 3.3%, compared to the linked quarter. Excluding the mortgage operations and exit costs, salaries and employee benefits expense decreased by $0.8 million compared to the linked quarter due to lower incentive compensation and bonus accruals. Also, marketing, advertising and promotion expense, consulting and professional fees, premises and equipment costs and other expenses decreased from the linked quarter, while loan expenses and deposit insurance premiums were higher. The increase in loan expenses reflects higher third party loan servicing costs related to franchise finance loan volume. The increase in deposit insurance premium was due primarily to asset growth, as well as the composition of loans and deposits.

Income Taxes

The Company recognized an income tax benefit of $1.8 million for the first quarter of 2023, compared to an income tax expense of $0.5 million and an effective tax rate of 7.3% for the fourth quarter of 2022 and an income tax expense of $1.8 million and an effective tax rate of 13.8% for the first quarter of 2022. The income tax benefit in the first quarter of 2023 reflects the net loss resulting from the partial charge-off of the participation loan and the recognition of mortgage exit costs described above.

Loans and Credit Quality

Total loans as of March 31, 2023 were $3.6 billion, an increase of $110.1 million, or 3.1%, compared to December 31, 2022, and an increase of $728.7 million, or 25.3%, compared to March 31, 2022. Total commercial loan balances were $2.8 billion as of March 31, 2023, an increase of $88.7 million, or 3.3%, compared to December 31, 2022, and an increase of $468.0 million, or 20.0%, compared to March 31, 2022. Compared to the linked quarter, the increase in commercial loan balances was driven primarily by growth in franchise finance, single tenant lease financing and small business lending balances, as well as combined growth in investor commercial real estate and construction balances. These items were partially offset by a decrease in the public finance portfolio as well as continued runoff in the healthcare finance portfolio.

Total consumer loan balances were $756.4 million as of March 31, 2023, an increase of $23.1 million, or 3.1%, compared to December 31, 2022, and an increase of $267.6 million, or 54.7%, compared to March 31, 2022. The increase compared to the linked quarter was due primarily to higher balances in the recreational vehicles and trailers loan portfolios as well as funded residential mortgages that were in the pipeline prior to the announced exiting of the business.

Total delinquencies 30 days or more past due were 0.13% of total loans as of March 31, 2023, compared to 0.17% at December 31, 2022 and 0.03% as of March 31, 2022. The decrease in delinquencies during the first quarter of 2023 was due primarily to a construction loan that became current in the first quarter of 2023. Nonperforming loans to total loans was 0.32% as of March 31, 2023, compared to 0.22% at December 31, 2022 and 0.25% as of March 31, 2022. Nonperforming loans totaled $11.4 million at March 31, 2023, up from $7.5 million at December 31, 2022. The increase was due primarily to one commercial and industrial (“C&I”) credit with a balance of $9.8

million that was moved to nonaccrual status late in the quarter. The Company subsequently recognized a partial charge-off of $4.7 million related to this loan due to negative developments following quarter end.

The allowance for credit losses (“ACL”) as a percentage of total loans was 1.02% as of March 31, 2023, compared to 0.91% as of December 31, 2022 and 0.98% as of March 31, 2022. The increase in the ACL reflects the day one Current Expected Credit Losses (“CECL”) adjustment of $3.0 million, as well as overall growth in the loan portfolio and changes in certain economic forecasts that impacted quantitative factors for certain portfolios.

Net charge-offs were $5.0 million in the first quarter of 2023, compared to net charge-offs of $0.2 million in the fourth quarter 2022. The increase was due almost wholly to the C&I participation loan discussed above. Net charge-offs to average loans totaled 57 bps in the first quarter.

The provision for loan losses in the first quarter was $7.2 million, compared to $2.1 million for the fourth quarter of 2022. The increase in provision for the quarter reflects the partial charge-off of the C&I participation loan discussed above as well as growth in the loan portfolio and the impact of economic forecasts on certain portfolios mentioned above.

Capital

As of March 31, 2023, total shareholders’ equity was $357.3 million, a decrease of $7.7 million, or 2.1%, compared to December 31, 2022, and a decrease of $17.4 million, or 4.6%, compared to March 31, 2022. The decrease in shareholders’ equity during the first quarter of 2023 was due primarily to stock repurchase activity, the day one CECL adjustment and the net loss during the quarter, partially offset by a decrease in accumulated other comprehensive loss. Book value per common share was $39.95 as of March 31, 2023, down from $40.26 as of December 31, 2022 and up from $38.69 as of March 31, 2022. Tangible book value per share was $39.43, down from $39.74 as of December 31, 2022 and up from $38.21 as of March 31, 2022.

In connection with its previously announced stock repurchase program, the Company repurchased 161,691 shares of its common stock during the first quarter of 2023 at an average price of $24.50 per share. The Company has repurchased $36.2 million of stock under its authorized programs to-date.
