Net Interest Income and Net Interest Margin

Net interest income was $30.1 million for the second quarter of 2026, compared to $30.5 million for the first quarter of 2026. The $417,000 decrease was due to a $773,000 increase in interest expense, offset by a $356,000 increase in interest income. The increase in interest expense was due mainly to an $829,000 increase in interest on subordinated notes as a result of the notes repricing from 4.00% to 6.98% effective April 1, 2026 and one more day in the quarter. The increase in interest income was due to the combination of a $725,000 increase in loan interest income as average loans increased and one more day in the quarter, partially offset by lower FHLB dividend income as the first quarter of 2026 included a special dividend of $430,000. There was no special dividend from the FHLB in the second quarter of 2026.

The net interest margin (“NIM”) decreased 9 basis points to 3.06% for the second quarter of 2026 from 3.15% for the first quarter of 2026. The NIM decrease included a 5 basis point decrease in the yield on average total interest-earning assets and a 4 basis point increase in the overall cost of funds. The yield on average total interest-earning assets decreased to 5.81% for the second quarter of 2026 from 5.86% for the first quarter of 2026, due mostly to the impact of a 4 basis point decrease from lower FHLB dividends and a 1 basis point decrease in the yield on average total loans.

The average total cost of funds increased 4 basis points to 3.00% for the second quarter of 2026 from 2.96% for the first quarter of 2026, due mostly to an increase in the cost of subordinated notes due to their repricing on April 1, 2026, partially offset by a 5 basis point decrease in the cost of average total deposits to 2.81%. Average noninterest-bearing deposits represented approximately 16% of average total deposits for both the second and first quarters of 2026. The period end weighted average interest rate for total deposits declined to 2.75% at June 30, 2026 from 2.79% at March 31, 2026.

Provision for Credit Losses

There was no provision for credit losses for the second quarter of 2026 compared to a $200,000 reversal for the first quarter of 2026. The second quarter 2026 provision for credit losses reflected a provision for loan losses of $77,000 and a negative provision for unfunded loan commitments of $77,000 due to a lower volume of unfunded loan commitments. The second quarter provision for loan losses was due mainly to the impact of net charge-offs, while portfolio credit quality trends, underlying economic forecast indicators, and changes in loan portfolio composition remained relatively stable. Net charge-offs in the second quarter of 2026 represented 0.01% of average loans on an annualized basis, compared to 0.00% for the first quarter of 2026.

Noninterest Income

Noninterest income for the second quarter of 2026 was $3.0 million, a decrease of $1.3 million from $4.3 million for the first quarter of 2026. The decrease in noninterest income was mainly due to lower gains from OREO of $1.1 million, and lower other income of $870,000, offset partially by higher gain on sale of loans of $640,000. The net loss on OREO was $221,000 in the second quarter compared to the net gain on OREO of $890,000 in the first quarter. The decrease in other income was due to the first quarter including a $484,000 recovery of a fully charged-off acquired loan and $360,000 of interest income on the tax refunds related to purchased federal tax credits; there were no similar items in the second quarter of 2026. The sale of $42.1 million of mortgage loans and $8.1 million of Small Business Administration (“SBA”) loans resulted in gains of $964,000 for the second quarter of 2026 compared to the sale of mortgage loans of $4.9 million and SBA loans of $4.0 million for gains of $324,000 for the first quarter of 2026.

Noninterest Expense

Noninterest expense for the second quarter of 2026 was $19.0 million, a decrease of $236,000 from $19.3 million for the first quarter of 2026. The decrease was mainly due to lower salaries and employee benefits of $216,000 due mostly to lower payroll taxes. The efficiency ratio was 57.46% for the second quarter of 2026, compared to 55.41% for the first quarter of 2026. The increase in the efficiency ratio is attributed mostly to lower net revenues.

Income Taxes

The effective tax rate was 28.0% for both the second and first quarters of 2026. The effective tax rate for 2026 is estimated to be 28.0% compared to 24.2% for 2025. The estimated effective tax rate for 2026 is expected to be higher than the effective tax rate in 2025 due to a higher multi-state blended tax rate and lower benefits from purchased Federal tax credits.

Balance Sheet

At June 30, 2026, total assets were $4.3 billion, an $80.7 million, or 8% annualized, increase compared to total assets of $4.2 billion at March 31, 2026, and a $185.0 million, or 4.5%, increase compared to total assets of $4.1 billion at June 30, 2025.

The decrease in loans in the second quarter of 2026 included payoffs/paydowns of $149.9 million, loans sold of $50.2 million, and $19.4 million transferred to OREO, offset by $158.9 million of originations with an average yield of 6.31%, $38.9 million in advances, and $6.0 million in purchases.

As of June 30, 2026, available for sale securities ("AFS") totaled $407.2 million, a decrease of $8.6 million from March 31, 2026, primarily related to maturities and paydowns of $63.3 million, offset by purchases of $55.0 million during the second quarter of 2026. As of June 30, 2026, net unrealized pre-tax losses totaled $20.9 million, a $0.5 million increase due to changes in market interest rates when compared to net unrealized pre-tax losses of $20.4 million as of March 31, 2026.

Deposits

Total deposits were $3.4 billion as of June 30, 2026, an increase of $50.8 million, or 6.1% annualized, compared to March 31, 2026 and an increase of $202.4 million, or 6.3%, compared to June 30, 2025. The increase in total deposits during the second quarter of 2026 was due to a $94.4 million increase in retail deposits, offset by a $43.6 million decrease in wholesale deposits. The increase in retail deposits included a $64.7 million increase in demand deposits and a $15.5 million increase in non-maturity interest-bearing accounts. Noninterest-bearing deposits totaled $591.6 million, or 17.5% of total deposits, at June 30, 2026, an increase of $64.7 million compared to March 31, 2026, and an increase of $47.7 million compared to June 30, 2025.

Credit Quality

Nonperforming assets totaled $43.6 million, or 1.02% of total assets, at June 30, 2026, down from $48.8 million, or 1.16% of total assets, at March 31, 2026, and down from $61.0 million, or 1.49% of total assets, at June 30, 2025. The decrease in nonperforming assets during the second quarter of 2026 included a decrease of $20.8 million in nonperforming loans partially offset by an increase of $15.6 million in OREO (included in “accrued interest and other assets”) to $19.8 million at June 30, 2026. OREO totaled $4.3 million at March 31, 2026, and $4.2 million at June 30, 2025. The increase in OREO during the second quarter of 2026 was primarily due to the transfer of one nonperforming construction loan to OREO, offset by the sale of the existing OREO properties for a net loss.

Nonperforming loans (“NPLs”) totaled $23.8 million, or 0.72% of total loans, at June 30, 2026, down $20.8 million from $44.6 million, or 1.34% of total loans, at March 31, 2026 and down $33.0 million from $56.8 million, or 1.76% of total loans, at June 30, 2025. The $20.8 million decrease in NPLs during the second quarter of 2026 was due to $19.4 million transferred to OREO, $1.3 million in payoffs/paydowns and $1.3 million upgraded to performing, partially offset by additions of $1.2 million.

Substandard loans totaled $61.5 million, or 1.86% of total loans, at June 30, 2026, down from $72.5 million, or 2.18% of total loans, at March 31, 2026 and $91.0 million, or 2.81% of total loans, at June 30, 2025. The $11.0 million decrease in substandard loans during the second quarter of 2026 was primarily due to $19.4 million transferred to OREO and $4.2 million in payoffs/paydowns, partially offset by additions of $12.6 million. Of the total substandard loans outstanding at June 30, 2026, there were $37.8 million, or 61% of such loans, on accrual status.

The $4.5 million decrease for the second quarter of 2026 was primarily due to payoffs/paydowns of $3.8 million, downgrades to substandard-rated loans of $1.8 million, and upgrades of $0.4 million to pass-rated loans, partially offset by additions of $1.5 million. As of June 30, 2026, all special mention loans were paying current.

30-89 day delinquent loans, excluding nonperforming loans, totaled $9.0 million, or 0.27% of total loans, at June 30, 2026, up from $7.9 million, or 0.24% of total loans, at March 31, 2026, and down from $18.0 million, or 0.56% of total loans, at June 30, 2025.

As of June 30, 2026, the allowance for credit losses totaled $44.1 million and was comprised of an allowance for loan losses of $43.7 million and a reserve for unfunded loan commitments of $407,000 (included in “accrued interest and other liabilities”).

The increase in shareholders' equity for the second quarter of 2026 was due mostly to net income of $10.1 million and stock-based compensation activity of $1.6 million, offset by common stock repurchases of $4.5 million and common stock cash dividends paid of $2.8 million.

Non-GAAP Reconciliations

Tangible Book Value Reconciliations

Tangible book value per share is a non-GAAP disclosure. Management measures tangible book value per share to assess the Company’s capital strength and business performance and believes this is helpful to investors as additional tools 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 as of the dates indicated.

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 this is 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 ROATCE to its most comparable GAAP measure:

Pre-Tax Pre-Provision Income

Management believes that pre-tax pre-provision (“PTPP”) income is a useful measure for investors to evaluate core operating performance, excluding the volatility of credit provision expenses/(reversals). PTPP income is calculated by subtracting noninterest expense from the sum of net interest income and noninterest income, as shown in the following table.
