“Our first quarter performance was highlighted by solid core revenue growth and net interest margin expansion,” said David Becker, Chairman and Chief Executive Officer. “We saw continued momentum in operating revenues for the sixth consecutive quarter from growth in net interest income. This was fueled by higher yields on earning assets and reduced funding costs, due to the ongoing expansion of our construction, commercial and industrial and national SBA programs, which delivered meaningful positive operating leverage.”

“We also achieved strong fintech deposit growth and made strategic enhancements to our loan mix, which have strengthened our balance sheet flexibility and bolstered interest income. At the same time, we’ve maintained excellent liquidity as reflected in our loans-to-deposits ratio.”

“Despite credit challenges in certain portfolios, our asset quality and capital positions remain strong. Looking ahead, we are well-positioned to drive future earnings growth and profitability by staying focused on our core strategies of diversifying revenue and optimizing our balance sheet. I am grateful to our team for their commitment and hard work in delivering long-term value for our stakeholders.”

Net interest income for the first quarter of 2025 was $25.1 million, compared to $23.6 million for the fourth quarter of 2024, and $20.7 million for the first quarter of 2024. On a fully taxable equivalent basis, net interest income for the first quarter of 2025 was $26.3 million, compared to $24.7 million for the fourth quarter of 2024, and $21.9 million for the first quarter of 2024.

Total interest income for the first quarter of 2025 was $76.8 million, a decrease of 1.2% compared to the fourth quarter of 2024, and an increase of 12.7% compared to the first quarter of 2024. On a fully- taxable equivalent basis, total interest income for the first quarter of 2025 was $78.0 million, a decrease of 1.2% compared to the fourth quarter of 2024, and an increase of 12.5% compared to the first quarter of 2024. The yield on average interest-earning assets for the first quarter of 2025 increased to 5.57% from 5.52% for the fourth quarter of 2024, due to a 6 basis point (“bp”) increase in the yield earned on loans and a 12 bp increase in the yield earned on securities, partially offset by a 31 bp decrease in the yield earned on other earning assets. Compared to the linked quarter, average loan balances, including loans held-for-sale, increased $113.8 million, or 2.8%, and the average balance of securities increased $60.2 million, or 7.2%, while the average balance of other earning assets decreased $191.1 million, or 30.0%.

Interest income earned on commercial loans was higher due primarily to increased average balances within the investor commercial real estate, public finance, small business lending, construction and commercial and industrial portfolios. This was partially offset by lower average balances in the healthcare and franchise finance portfolios. The continued shift in the loan mix reflects the Company’s focus on higher-yielding variable rate products, in part, to help improve the interest rate risk profile of the balance sheet.

In the consumer loan portfolio, interest income was down due primarily to lower average balances in the residential mortgage, recreational vehicles and home equity portfolios. This activity was partially offset by new originations in the trailers portfolio.

The yield on funded portfolio loan originations was 7.78% in the first quarter of 2025, an increase of 50 bps compared to the fourth quarter of 2024, and a decrease of 107 bps compared to the first quarter of 2024, reflective of 100 bps of Fed rate cuts in the second half of 2024.

Interest income earned on securities during the first quarter of 2025 increased $0.7 million, or 8.5%, compared to the fourth quarter of 2024, driven by an increase in both average balances and the yield earned on the portfolio. Interest income earned on other earning asset balances declined $2.8 million, or 35.6%, in the first quarter of 2025 compared to the linked quarter, due to the decrease in average cash balances and lower yields earned on those balances following the Fed rate cuts in the second half of 2024.

Total interest expense for the first quarter of 2025 was $51.7 million, a decrease of $2.5 million, or 4.6%, compared to the linked quarter, as both the average balance and the cost of funds related to total interest-bearing liabilities declined. Interest expense related to interest-bearing deposits decreased $1.5 million, or 3.0%, driven primarily by lower average balances and lower cost of funds related to CDs, money market accounts and brokered deposits.

This was partially offset by an increase in the average balance of interest-bearing demand deposits, as well as an increase in the cost of funds related to these deposits as they now include fintech deposits formerly classified as brokered. Overall, the cost of interest-bearing deposits declined during the quarter to 4.01%, compared to 4.13% for the fourth quarter of 2024.

Average CD balances decreased $37.7 million, or 1.8%, compared to the linked quarter, while the cost of funds decreased 16 bps. The weighted average cost of new CDs during the first quarter of 2025 was 4.07%, or 99 bps lower than the cost of maturing CDs. The average balance of money market accounts decreased $14.3 million, or 1.2%, while the cost of funds decreased 19 bps following Fed rate cuts from the prior quarter. Furthermore, the average balance of brokered deposits decreased $31.1 million, or 5.4%, while the cost of funds declined 22 bps due to higher rates on maturing brokered CDs in the fourth quarter of 2024. Near the end of the quarter, the Company paid down $200.0 million of higher cost brokered deposits, which is expected to positively impact deposit costs in future periods.

When combined with deposits formerly classified as fintech – brokered deposits, the average balance of interest-bearing demand deposits increased $173.2 million, or 22.1%, compared to the fourth quarter of 2024 due to continued strong growth in fintech deposits, while the cost of funds increased 41 bps due to the change in deposit mix.

Interest expense was also positively impacted by the cost of other borrowed funds, which decreased $1.0 million, or 19.6%, during the first quarter of 2025 as compared to the linked quarter. The average balance of FHLB advances declined $127.6 million, or 30.1%, during the first quarter of 2025 following significant paydowns made during the fourth quarter of 2024.

Net interest margin (“NIM”) was 1.82% for the first quarter of 2025, up from 1.67% for the fourth quarter of 2024 and up from 1.66% for the first quarter of 2024. Fully taxable equivalent NIM (“FTE NIM”) was 1.91% for the first quarter of 2025, up from 1.75% for both the fourth quarter and first quarter of 2024. The increases in NIM and FTE NIM reflect the combination of deploying cash balances into higher yielding loans and securities and continued improvement in the cost of funds related to deposits.

Noninterest income for the first quarter of 2025 was $10.4 million, compared to $15.9 million for the fourth quarter of 2024, and $8.3 million for the first quarter of 2024. During the fourth quarter of 2024, the Company recognized $4.7 million of prepayment and terminated interest rate swap gains related to the paydown of FHLB advances. Excluding these gains, noninterest income for the first quarter of 2025 was down $0.8 million, or 6.9%, compared to the linked quarter. Gain on sale of loans totaled $8.6 million for the first quarter of 2025, up $0.1 million, or 0.9%, from the linked quarter. Gain on sale revenue consisted almost entirely of sales of U.S. Small Business Administration (“SBA”) 7(a) guaranteed loans during the first quarter of 2025. SBA loan sale volume was up 1.9%, while net premiums decreased 6 bps compared to the linked quarter. Net loan servicing revenue decreased by $0.6 million due mainly to a lower fair value adjustment to the loan servicing asset. Additionally, other noninterest income, excluding the nonrecurring items from the fourth quarter of 2024, decreased $0.3 million due to lower income from fund investments, partially offset by higher fintech revenue.

Noninterest expense totaled $23.6 million for the first quarter of 2025, compared to $24.0 million for the fourth quarter of 2024, and $21.0 million for the first quarter of 2024. The decrease of $0.4 million, or 1.7%, compared to the linked quarter was due primarily to lower salaries and employee benefits, partially offset by higher consulting and professional fees and loan expenses. The decrease in salaries and employee benefits was driven primarily by lower incentive compensation, partially offset by annual resets on certain employee benefits and payroll taxes.

The increase in consulting and professional fees was due mainly to seasonally higher legal expenses. The increase in loan expenses was due to an increase in collection costs.

The Company recorded an income tax benefit of $0.9 million for the first quarter of 2025, compared to income tax expense of $1.0 million and an effective tax rate of 12.0% for the fourth quarter of 2024, and income tax expense of $0.4 million and an effective tax rate of 7.6% for the first quarter of 2024.

Total loans as of March 31, 2025 were $4.3 billion, an increase of $83.8 million, or 2.0%, compared to December 31, 2024, and an increase of $344.6 million, or 8.8%, compared to March 31, 2024. Total commercial loan balances were $3.4 billion as of March 31, 2025, an increase of $89.5 million, or 2.7%, compared to December 31, 2024, and an increase of $350.9 million, or 11.4%, compared to March 31, 2024. Compared to the linked quarter, the increase in commercial loan balances was driven primarily by growth in construction, investor commercial real estate, small business lending and commercial and industrial balances. These increases were partially offset by decreases in the franchise finance and healthcare finance portfolios.

Total consumer loan balances were $797.7 million as of March 31, 2025, a decrease of $3.7 million, or 0.5%, compared to December 31, 2024, and an increase of $4.3 million, or 0.5% compared to March 31, 2024. The decrease compared to the linked quarter was due primarily to lower balances in the residential mortgages, recreational vehicles and other consumer loans portfolios, partially offset by an increase in the trailers portfolio.

Total delinquencies 30 days or more past due, excluding nonperforming loans, were 0.77% of total performing loans as of March 31, 2025, compared to 0.63% at December 31, 2024, and 0.29% as of March 31, 2024. The increase compared to the linked quarter was due primarily to an increase in delinquencies in the small business lending and franchise finance portfolios, some of which was due to the timing of principal and interest payments. Subsequent to quarter end, payments were received from certain borrowers and as of the date of this release, delinquencies 30 days or more past due declined to 0.64% of total performing loans.

Nonperforming loans were 0.80% of total loans as of March 31, 2025, compared to 0.68% as of December 31, 2024, and 0.33% as of March 31, 2024. Nonperforming loans totaled $34.2 million as of March 31, 2025, compared to $28.4 million as of December 31, 2024, and $13.1 million as of March 31, 2024. The increase in nonperforming loans during the first quarter of 2025 was due primarily to franchise finance and small business lending loans that were placed on nonaccrual during the quarter. At March 31, 2025, there were $11.5 million of specific reserves held against the balance of nonperforming loans.

The allowance for credit losses (“ACL”) as a percentage of total loans was 1.11% as of March 31, 2025, compared to 1.07% as of December 31, 2024, and 1.05% as of March 31, 2024. The increase in the ACL reflects the addition of specific reserves related to franchise finance and small business lending loans that were placed on nonaccrual during the quarter and growth in the overall loan portfolio, partially offset by the impact of economic metrics on qualitative factors in certain portfolios. The net increase to specific reserves totaled $3.3 million, of which, $2.5 million related to franchise finance and $0.8 million related to small business lending.

Net charge-offs of $9.7 million were recognized during the first quarter of 2025, resulting in net charge-offs to average loans of 0.92%, compared to $9.4 million, or 0.91%, for the fourth quarter of 2024, and $0.5 million, or 0.05%, for the first quarter of 2024. Net charge-offs in the first quarter of 2025 were elevated as the Company continued to take action to resolve problem loans in the small business lending and franchise finance portfolios.

Approximately $5.8 million of net charge-offs recognized during the quarter were related to franchise finance loans with $2.6 million of existing specific reserves.

The provision for credit losses in the first quarter of 2025 was $11.9 million, compared to $7.2 million for the fourth quarter of 2024, and $2.4 million for the first quarter of 2024. The provision for the first quarter of 2025 was driven primarily by the elevated net charge-offs, the additional specific reserves discussed above and overall growth in the loan portfolio, partially offset by the impact of economic metrics on qualitative factors in certain portfolios and a decrease in unfunded commitments.

As of March 31, 2025, total shareholders’ equity was $387.7 million, an increase of $3.7 million, or 1.0%, compared to December 31, 2024, and an increase of $21.0 million, or 5.7%, compared to March 31, 2024. The increase in total shareholders’ equity as of March 31, 2025 compared to the linked quarter was due primarily to the decrease in accumulated other comprehensive loss and net income earned during the quarter. Book value per common share increased to $44.58 as of March 31, 2025, up from $44.31 as of December 31, 2024, and $42.37 as of March 31, 2024. Tangible book value per share was $44.04 as of March 31, 2025, up from $43.77 as of December 31, 2024, and $41.83 as of March 31, 2024.
