“Core banking metric continue to improve, with our second quarter results reflecting strong growth in net interest income and continued improvement in our net interest margin. We have now delivered

Net interest income for the second quarter of 2025 was $28.0 million, compared to $25.1 million for the first quarter of 2025, and $21.3 million for the second quarter of 2024. On a fully-taxable equivalent basis, net interest income for the second quarter of 2025 was $29.1 million, compared to $26.3 million for the first quarter of 2025, and $22.5 million for the second quarter of 2024.

Total interest income for the second quarter of 2025 was $80.9 million, an increase of 5.3% compared to the first quarter of 2025, and an increase of 14.0% compared to the second quarter of 2024. On a fully-taxable equivalent basis, total interest income for the second quarter of 2025 was $82.0 million, an increase of 5.2% compared to the first quarter of 2025, and an increase of 13.7% compared to the second quarter of 2024. The yield on average interest-earning assets for the second quarter of 2025 increased to 5.65% from 5.57% for the first quarter of 2025, due to an 8 basis point (“bp”) increase in the yield earned on loans and a 7 bp increase in the yield earned on securities, partially offset by a 6 bp decrease in the yield earned on other earning assets. Compared to the linked quarter, average loan balances, including loans held-for-sale, increased $164.3 million, or 3.9%, and the average balance of securities increased $33.1 million, or 3.7%, while the average balance of other earning assets decreased $48.5 million, or 10.9%.

Interest income earned on commercial loans was higher due primarily to increased average balances within the small business lending (including loans held-for-sale), construction, single tenant lease financing, commercial and industrial and investor commercial real estate portfolios. This was partially offset by lower average balances in the franchise finance and healthcare finance portfolios.

In the consumer loan portfolio, interest income was up modestly due primarily to higher average balances in the trailers portfolio, partially offset by lower average balances in the residential mortgage portfolio.

The yield on funded portfolio loan originations was 7.55% in the second quarter of 2025, a decrease of 23 bps compared to the first quarter of 2025, and a decrease of 133 bps compared to the second quarter of 2024, reflective of 100 bps of Fed rate cuts in the second half of 2024.

Interest income earned on securities during the second quarter of 2025 increased $0.6 million, or 6.5%, compared to the first quarter of 2025, driven by an increase in both average balances and the yield earned on the portfolio. This was offset by a decline in interest income earned on other earning assets of $0.6 million, or 11.1%, in the second quarter of 2025 compared to the linked quarter, due to both the decrease in average cash balances and lower yields earned on those balances.

Total interest expense for the second quarter of 2025 was $52.9 million, an increase of $1.2 million, or 2.2%, compared to the linked quarter, as the average balance of interest-bearing liabilities increased $143.2 million, or 2.7%, partially offset by a decline in the cost of related funds of 6 bps to 3.96%. Interest expense related to interest-bearing deposits decreased $0.8 million, or 1.7%, driven primarily by lower average balances and lower cost of funds related to CDs, brokered deposits and money market accounts. 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. Overall, the cost of interest-bearing deposits declined to 3.92% during the second quarter of 2025, compared to 4.01% for the first quarter of 2025.

Average CD balances decreased $53.7 million, or 2.6%, compared to the linked quarter, while the cost of funds decreased 14 bps. The weighted average cost of new CDs during the second quarter of 2025 was 4.27%, 60 bps lower than the cost of maturing CDs. The average balance of brokered deposits decreased $206.7 million, or 38.2%, as the Company paid down $200.0 million of these deposits near the end of the first quarter of 2025, while the cost of funds declined 6 bps. Furthermore, the average balance of money market accounts decreased $34.0 million, or 2.8%, while the cost of funds decreased 3 bps.

Partially offsetting this activity was growth in the average balance of interest-bearing demand deposits, which increased $270.1 million, or 28.2%, compared to the first quarter of 2025 as growth in fintech deposits remained strong throughout the quarter. Furthermore, the cost of funds related to these deposits increased 23 bps during the quarter.

Additionally, interest expense was negatively impacted by the cost of other borrowed funds in the second quarter of 2025, as the Company used FHLB advances to manage short term liquidity needs earlier in the quarter. The average balance of other borrowed funds increased $166.3 million, or 41.4%, compared to the linked quarter, while the related cost of funds increased 16 bps. However, strong deposit growth later in the quarter allowed the Company to pay down all short term FHLB advances prior to quarter end, as ending balances were down $130.5 million, or 33.0%, compared to the first quarter of 2025.

Net interest margin (“NIM”) was 1.96% for the second quarter of 2025, up from 1.82% for the first quarter of 2025 and up from 1.67% for the second quarter of 2024. Fully-taxable equivalent NIM (“FTE NIM”) was 2.04% for the second quarter of 2025, up from 1.91% for the first quarter of 2025 and up from 1.76% for the second quarter of 2024. The increases in NIM and FTE NIM reflect the combination of deploying cash balances into higher-yielding loans and securities, as well as continued improvement in the cost of deposits.

Noninterest income for the second quarter of 2025 was $5.6 million, compared to $10.4 million for the first quarter of 2025, and $11.0 million for the second quarter of 2024. The decrease compared to the linked quarter was due primarily to gain on sale of loans, which totaled $1.7 million for the second quarter of 2025, down $6.9 million, or 80.7%, from the first quarter of 2025. The decline was due to a significant decrease in sales of U.S. Small Business Administration (“SBA”) 7(a) guaranteed loans as the Company implemented a process change to hold SBA loans held-for-sale longer before selling into the secondary market. This is expected to have a one quarter effect as gain on sale revenue should revert to normalized levels in the third quarter of 2025 as evidenced by the higher balance of loans held-for-sale on the balance sheet as of June 30, 2025, which is up $94.8 million, or 298.7%, compared to March 31, 2025. The decline in gain on sale revenue was partially offset by higher other noninterest income, which increased $2.1 million, or 289.9%, compared to the linked quarter due primarily to a planned distribution from a fund investment.

Noninterest expense totaled $21.8 million for the second quarter of 2025, compared to $23.6 million for the first quarter of 2025, and $22.3 million for the second quarter of 2024. The decrease of $1.8 million, or 7.5%, compared to the linked quarter was due primarily to lower salaries and employee benefits and lower consulting and professional fees, partially offset by higher other noninterest expense. The decrease in salaries and employee benefits was driven primarily by a reduction in incentive compensation. The decrease in consulting and professional fees was due mainly to lower outsourced audit fees and seasonally higher legal expense in the linked quarter. The increase in other noninterest expense was due primarily to higher fintech volume activity.

The Company recorded an income tax benefit of $2.1 million for the second quarter of 2025, compared to an income tax benefit of $0.9 million for the first quarter of 2025, and income tax expense of $0.2 million and an effective tax rate of 3.6% for the second quarter of 2024.

Total loans as of June 30, 2025, were $4.4 billion, an increase of $108.2 million, or 2.5%, compared to March 31, 2025, and an increase of $401.4 million, or 10.1%, compared to June 30, 2024. Total commercial loan balances were $3.5 billion as of June 30, 2025, an increase of $108.2 million, or 3.2%, compared to March 31, 2025, and an increase of $412.3 million, or 13.2%, compared to June 30, 2024. Compared to the linked quarter, the increase in commercial loan balances was driven primarily by growth in investor commercial real estate, commercial and industrial and small business lending balances. These increases were partially offset by decreases in the construction, franchise finance and healthcare finance portfolios. The decrease in construction balances was due to projects that were completed during the second quarter of 2025 and transferred to investor commercial real estate.

Total consumer loan balances were $797.2 million as of June 30, 2025, a decrease of $0.5 million, or 0.1%, compared to March 31, 2025, and a decrease of $3.3 million, or 0.4%, compared to June 30, 2024. The decrease compared to the linked quarter was due primarily to lower balances in residential mortgage, recreational vehicles and home equity portfolios, partially offset by an increase in the trailers and other consumer loans portfolios.

Total delinquencies 30 days or more past due, excluding nonperforming loans, were 0.62% of total performing loans as of June 30, 2025, compared to 0.77% at March 31, 2025, and 0.56% as of June 30, 2024. The decrease compared to the linked quarter was due primarily to a decrease in delinquencies in the small business lending portfolio.

Nonperforming loans were 1.00% of total loans as of June 30, 2025, compared to 0.80% as of March 31, 2025, and 0.33% as of June 30, 2024. Nonperforming loans totaled $43.5 million as of June 30, 2025, compared to $34.2 million as of March 31, 2025, and $13.0 million as of June 30, 2024.

The increase in nonperforming loans during the second quarter of 2025 was due primarily to franchise finance and small business lending loans that were placed on nonaccrual during the quarter, partially offset by small business lending and franchise finance loans that were charged off. At June 30, 2025, there were $8.9 million of specific reserves held against the balance of nonperforming loans.

The allowance for credit losses (“ACL”) as a percentage of total loans was 1.07% as of June 30, 2025, compared to 1.11% as of March 31, 2025, and 1.10% as of June 30, 2024. The decrease in the ACL compared to the linked quarter reflects the removal of $5.2 million in specific reserves related to small business loans that were charged off during the quarter, as well as the removal of $2.2 million in reserves that were related to franchise finance charge-offs. These decreases were partially offset by $4.5 million of specific reserves applied to franchise finance loans during the quarter, as well as overall growth in the loan portfolio.

Net charge-offs of $14.3 million were recognized during the second quarter of 2025, resulting in net charge-offs to average loans of 1.31%, compared to $9.7 million, or 0.92%, for the first quarter of 2025, and $1.4 million, or 0.14%, for the second quarter of 2024. Net charge-offs in the second 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 $11.9 million of net charge-offs recognized during the quarter were related to small business lending and $2.2 million were related to franchise finance loans, with $7.3 million of existing specific reserves previously applied to these loans.

The provision for credit losses in the second quarter of 2025 was $13.6 million, compared to $11.9 million for the first quarter of 2025, and $4.0 million for the second quarter of 2024. The provision for the second quarter of 2025 was driven primarily by elevated net charge-offs and overall growth in the loan portfolio, partially offset by a net decrease in specific reserves.

As of June 30, 2025, total shareholders’ equity was $390.2 million, an increase of $2.5 million, or 0.6%, compared to March 31, 2025, and an increase of $18.3 million, or 4.9%, compared to June 30, 2024. The increase in total shareholders’ equity as of June 30, 2025, compared to the linked quarter was due primarily to the decrease in accumulated other comprehensive loss. Book value per common share increased to $44.79 as of June 30, 2025, up from $44.58 as of March 31, 2025, and $42.91 as of June 30, 2024. Tangible book value per share was $44.25 as of June 30, 2025, up from $44.04 as of March 31, 2025, and $42.37 as of June 30, 2024.
