This positive trend in operating leverage improved the efficiency ratio from 53.9% for the three months ended June 30, 2025 to 50.5% for the three months ended June 30, 2026.Strong Asset Quality – Overall credit quality of the loan portfolio remains exceptional. As of June 30, 2026, the Company did not have any non-accrual loans and had no other real estate owned assets.

The dividend is payable on August 26, 2026 to shareholders of record at the close of business on August 5, 2026. The quarterly cash dividend represents an 11.1% increase over the quarterly cash dividend of $0.09 declared on April 28, 2026.Robust Capitalization – Each of the Bank’s regulatory capital ratios remained well in excess of the regulatory well-capitalized thresholds as of June 30, 2026. Chris Bergstrom, President and Chief Executive Officer, commented, “The Company achieved two significant growth milestones during the second quarter. We exceeded $2.4 billion in total assets and surpassed $2.0 billion in gross loans. John Marshall produced $41 million in loan growth during the second quarter and our pipeline for the third quarter looks strong. Quarterly earnings of $7 million marked the eighth consecutive quarter of increased net income and resulted in earnings per share growth of 38.9% when compared to the second quarter of 2025. Asset quality remains exemplary and the Bank is very well-capitalized. As an expression of the soundness of our balance sheet and confidence in the outlook for our financial performance, the Board of Directors increased our quarterly cash dividend to $0.10 per common share. On an annualized basis, the dividend represents a 33% increase versus a year ago. We are pleased to have increased our return on assets to 1.20% and our return on equity to 10.34% and believe that we are well-positioned to grow the balance sheet, profits and shareholder value.” Balance Sheet, Liquidity and Credit Quality The Company carried balance sheet growth momentum into the second quarter of 2026 and exceeded $2.4 billion in total assets and $2.0 billion in total loans for the first time in the Company’s history.

The increase in loans over the preceding twelve months was primarily attributable to growth in construction & development loans and residential mortgage loans.

The carrying value of the Company’s fixed income securities portfolio was $213.7 million at June 30, 2026, $213.8 million at March 31, 2026, and $215.8 million at June 30, 2025. During the most recent quarter, the Company purchased nine fixed income securities, designated as available-for-sale, with a total carrying amount of $17.8 million and a weighted average purchase yield of 4.39%. Fixed income securities which matured during the most recent quarter had an average yield of 1.32%. As of June 30, 2026, 95.4% of our bond portfolio carried the implied guarantee of the United States government or one of its agencies. At June 30, 2026, 74.7% of the fixed income portfolio was invested in amortizing bonds, which provides the Company with a source of steady cash flow. At June 30, 2026, the fixed income portfolio had an estimated weighted average life of 4.0 years. The available-for-sale portfolio comprised approximately 61% of the fixed income securities portfolio and had a weighted average life of 3.5 years at June 30, 2026. The held-to-maturity portfolio comprised approximately 39% of the fixed income securities portfolio and had a weighted average life of 4.9 years at June 30, 2026. The Company did not have an allowance for credit losses on held-to-maturity securities as of June 30, 2026 or December 31, 2025. As of June 30, 2026, 93.1% of our held-to-maturity portfolio carried the implied guarantee of the United States government or one of its agencies. The Company’s balance sheet remains highly liquid. The Company’s liquidity position, defined as the sum of cash, unencumbered securities and available secured borrowing capacity, totaled $827.2 million as of June 30, 2026 compared to $881.0 million as of March 31, 2026 and represented 34.4% and 37.5% of total assets, respectively. In addition to available secured borrowing capacity, the Bank had available federal funds lines of $70.0 million at June 30, 2026. Total deposits increased $5.3 million or 1.1% annualized to $1.99 billion at June 30, 2026 compared to $1.99 billion at March 31, 2026, and increased $96.1 million or 5.1% from $1.90 billion at June 30, 2025. During the preceding twelve months, total interest-bearing deposits increased $83.2 million or 5.7%, while total non-interest bearing deposits increased $12.9 million or 2.9% over the same period. Detail on the deposit activity can be seen in the Loan, Deposit and Borrowing Detail table. As of June 30, 2026, the Company had $703.8 million of deposits that were not insured or not collateralized compared to $691.5 million and $656.0 million at December 31, 2025 and June 30, 2025, respectively. Federal Home Loan Bank (“FHLB”) advances remained unchanged at $56.0 million as of June 30, 2026 compared to March 31, 2026 and June 30, 2025. As of June 30, 2026, the FHLB advances had a weighted average fixed interest rate of 3.85%. In addition to outstanding FHLB advances, total borrowings as of June 30, 2026 included federal funds purchased and subordinated debt totaling $40.0 million and $24.9 million, respectively. Shareholders’ equity increased $20.1 million or 7.9% to $273.8 million at June 30, 2026 compared to $253.7 million at June 30, 2025. Book value per share was $19.40 as of June 30, 2026 compared to $17.83 as of June 30, 2025, an increase of 8.8%. The year-over-year increase in shareholders’ equity and book value per share was primarily due to the Company’s earnings over the previous twelve months and a decrease in accumulated other comprehensive loss, resulting from an increase in the market value of our available-for-sale investment portfolio. These increases were partially offset by cash dividends paid and a reduction of additional paid-in capital due to the Company’s share repurchases during the period. The Bank’s capital ratios remained well above regulatory thresholds for well-capitalized banks. As of June 30, 2026, the Bank’s total risk-based capital ratio was 16.7%, compared to 16.3% at both December 31, 2025 and June 30, 2025. As of June 30, 2026, the Company did not have any non-accrual loans and had no other real estate owned. A commercial SBA 7(a) loan previously designated as non-accrual at March 31, 2026, was paid in full by the SBA on June 2, 2026. During the three months ended June 30, 2026, the Company charged-off three commercial SBA 7(a) loans in the total amount of $172 thousand. These charge-offs represented the unguaranteed portions of the loans and we expect the SBA to fully pay the guaranteed portions. At June 30, 2026, the allowance for loan credit losses was $20.2 million or 1.00% of outstanding loans, net of unearned income, compared to $20.0 million or 1.01% of outstanding loans, net of unearned income, at March 31, 2026. The increase in the allowance for credit losses during the most recent quarter was predominantly driven by loan portfolio growth and the associated change in the portfolio mix. Asset quality remains strong. Management believes the current allowance for credit losses is appropriate given the composition and performance of the loan portfolio. At June 30, 2026, the allowance for credit losses on unfunded loan commitments was $1.1 million compared to $1.2 million at March 31, 2026, due to a lower amount of available loan commitments. The Company believes its owner occupied and non-owner occupied commercial real estate portfolios continue to be of sound credit quality. The following table demonstrates their strong debt-service-coverage and loan-to-value ratios as of June 30, 2026.

For the three months ended June 30, 2026, net interest income increased $2.4 million or 16.1% to $17.3 million compared to $14.9 million for the three months ended June 30, 2025. During the same period, interest income grew $1.9 million or 6.8%, driven by higher interest income on loans, while interest expense declined by $0.5 million or 3.9%, predominantly due to lower interest expense on all interest-bearing deposit categories. The annualized net interest margin for the second quarter of 2026 was 2.99% compared to 2.69% for the same period in 2025. The increase in net interest margin was primarily due to increases in average balances and yields of the loan portfolio coupled with lower rates on interest-bearing deposits. The cost of interest-bearing liabilities was 3.13% for the second quarter of 2026 compared to 3.38% for the same quarter in the prior year driven by the 26 basis point decline in rates on interest-bearing deposits. Rates declined across all deposit categories, most notably in time deposits, money market accounts, and savings accounts, which declined by 35 basis points, 28 basis points, and 18 basis points, respectively. The yield on interest-earning assets was 5.13% for the second quarter of 2026 compared to 5.03% for the same period in 2025 primarily due to an 11 basis point increase in loan yield coupled with a 35 basis point increase in securities yield. These increases were partially offset by a 75 basis point decrease in yield on interest-bearing deposits in other banks, as a result of three federal funds rate cuts totaling 75 basis points during the preceding twelve months. Average loans increased by $110.5 million between the three months ended June 30, 2026 and the three months ended June 30, 2025, which was primarily attributable to origination volume in the construction & development and residential mortgage loan portfolios subsequent to June 30, 2025. The Company recorded a $258 thousand provision for credit losses for the second quarter of 2026 compared to $537 thousand for the second quarter of 2025. Provision for credit losses on funded loans totaled $384 thousand, while provision for credit losses on unfunded loan commitments was a recovery of $126 thousand during the three months ended June 30, 2026. The provision for credit losses on funded loans during the most recent quarter reflected the growth of the Company’s loan portfolio, and the related change in the portfolio mix, in combination with the impact of the previously mentioned charge-offs. Recovery of the provision for credit losses on unfunded loan commitments was due to a lower amount of available loan commitments at June 30, 2026 as compared to March 31, 2026. Non-interest income increased $936 thousand or 184.6% during the second quarter of 2026 compared to the second quarter of 2025, which was primarily attributable to a $835 thousand gain recognized on a sale of the Company’s interest in one of its equity investment units. Excluding this gain, non-interest income increased $101 thousand or 19.9% during the most recent quarter as compared to the prior year quarter, as a result of a $80 thousand increase in mark-to-market adjustments on investments related to the Company’s non-qualified deferred compensation plan, a $50 thousand increase in other fee income due to higher early termination fees on customers’ time deposits, and a $43 thousand increase in other income, as a result of receipt of a class action settlement claim from a health insurance carrier. These increases were partially offset by a $61 thousand decrease in gain on sale of SBA 7(a) loans. Non-interest expense increased $1.2 million or 14.2% during the second quarter of 2026 compared to the second quarter of 2025 primarily resulting from an increase in salaries and employee benefits and higher marketing expense. Salaries and employee benefits increased $979 thousand, as a result of increases in incentive compensation, higher mark-to-market adjustments on the Company’s non-qualified deferred compensation plan and the impact of the annual salary merit increase. Incentive compensation accruals can fluctuate materially from quarter to quarter, based upon the Company’s financial performance and conditions measured against, among other evaluation criteria, our strategic plan and budget. At the end of each year, the ultimate determination of the incentive compensation is approved by the Board of Directors. Marketing expense increased $131 thousand mainly due to various public relations and advertising initiatives. For the three months ended June 30, 2026, annualized non-interest expense to average assets was 1.63% compared to 1.49% for the three months ended June 30, 2025. This increase was primarily due to the growth in non-interest expense outpacing the growth in average assets during the period. For the three months ended June 30, 2026, the efficiency ratio declined to 50.5% compared to 53.9% for the three months ended June 30, 2025. The improvement in the efficiency ratio was due to a 21.7% growth in total revenue, which outpaced a 14.2% increase in non-interest expense over the period. Return on average assets for the quarter ended June 30, 2026 was 1.20% and return on average equity was 10.34% compared to 0.91% and 8.06%, respectively, for the second quarter of 2025. Year-to-Date Results The Company reported net income of $13.1 million for the six months ended June 30, 2026, an increase of $3.2 million or 32.4% when compared to the same period in 2025. Net interest income for the six months ended June 30, 2026 increased $4.8 million or 16.6% compared to the same period of 2025. The annualized net interest margin for the six months ended June 30, 2026 was 2.93% as compared to 2.63% for the same period in the prior year. These increases were driven primarily by the increase in average balances and yields of the loan portfolio in combination with a decrease in rates of interest-bearing deposits. The cost of interest-bearing liabilities was 3.14% for the six months ended June 30, 2026 compared to 3.43% for the six months ended June 30, 2025. The decrease in the cost of interest-bearing liabilities was primarily due to a 30 basis point decrease in the cost of interest-bearing deposits as a result of the repricing of the Company’s time deposits coupled with a decrease in rates offered on money market, NOW and savings deposit accounts since the second quarter of 2025. The yield on interest-earning assets was 5.10% for the six months ended June 30, 2026 compared to 5.01% for the same period in 2025. The increase in yield on interest-earning assets was primarily due to a nine basis point and a 32 basis point increase in yields on the Company’s loans and securities, respectively, as assets repriced at higher prevailing interest rates subsequent to the second quarter of 2025. Average loans increased $108.2 million between the six months ended June 30, 2026 and 2025, which was primarily attributable to origination volume in the construction & development, and residential mortgage loan portfolios subsequent to June 30, 2025. The Company recorded a $281 thousand provision for credit losses for the six months ended June 30, 2026 compared to a $707 thousand provision for credit losses for the six months ended June 30, 2025. The provision for credit losses during the six months ended June 30, 2026 was primarily a result of changes in the composition and volume of the loan portfolio in combination with the impact of the previously mentioned charge-offs recorded during the most recent quarter. All other model assumptions, including economic forecasts used in the quantitative portion of the model, stayed relatively stable during the period. Non-interest income increased $716 thousand or 70.8% during the six months ended June 30, 2026 compared to the same period of 2025. The increase was primarily driven by previously mentioned $835 thousand gain on sale of the Company’s investment unit in combination with a $51 thousand increase in other income driven by the receipt of a class action settlement claim from a health insurance carrier and a $43 thousand increase in mark-to-market adjustments on investments related to the Company’s non-qualified deferred compensation plan. These increases were partially offset by a $153 thousand decrease in bankers insurance commission coupled with a $91 thousand decline in gain on sale of SBA 7(a) loans. Non-interest expense increased $1.9 million or 11.2% during the six months ended June 30, 2026 compared to the same period in 2025 predominantly due to a $1.5 million or 14.6% increase in salaries and employee benefits, as discussed above in the quarterly results. Other expenses increased $301 thousand or 6.2% for the six months ended June 30, 2026 compared to the six months ended June 30, 2025. Increases were primarily in state franchise tax and FDIC insurance, due to higher assessment bases, and an increase in marketing expense. Furniture and equipment expenses increased $63 thousand or 10.0% for the six months ended June 30, 2026 compared to the same period in 2025. The increase was due to investment and maintenance in technology. For the six months ended June 30, 2026, annualized non-interest expense to average assets was 1.59% compared to 1.49% for the six months ended June 30, 2025. For the six months ended June 30, 2026, the efficiency ratio was 51.8% compared to 55.1% for the six months ended June 30, 2025. The improvement in the efficiency ratio was due to an 18.4% growth in total revenue, which outpaced an 11.2% increase in non-interest expense over the period. Return on average assets for the six months ended June 30, 2026 was 1.13% and return on average equity was 9.77% compared to 0.89% and 7.91%, respectively, for the six months ended June 30, 2025.
