Operating Highlights

Net interest income totaled $19.7 million for the first quarter of 2026, a decrease of approximately $119 thousand, or 0.6%, from $19.9 million for the fourth quarter of 2025, and an increase of approximately $3.0 million, or 17.8% from the first quarter of 2025. The Company’s net interest margin decreased by 1 basis point to 3.59% for the first quarter of 2026, compared to 3.60% for the fourth quarter of 2025, and increased 21 basis points from the first quarter of 2025.

The yield on average interest-earning assets for the first quarter of 2026 decreased to 5.92% from 5.98% for the fourth quarter of 2025. This decrease was primarily related to an overall yield decrease in interest-earning assets, primarily federal funds sold, loans held for sale, and investment securities due to recent interest rate cuts, notwithstanding significant growth in average total earning assets. Compared to the first quarter of 2025, yields on earning assets decreased 13 basis points to 5.92% from 6.05%. The decrease was primarily attributable to the aforementioned interest rate cuts during 2025.

The Company’s total cost of funds was 2.55% for the first quarter of 2026, a decrease of 5 basis points and 30 basis points compared with the fourth and first quarters of 2025, respectively. Deposit costs decreased 5 and 26 basis points during the first quarter of 2026 to 2.54%, compared to 2.59% and 2.80% in the fourth and first quarters of 2025, respectively. The cost of interest-bearing deposits decreased 8 basis points during the first quarter of 2026 to 3.01%, compared with 3.09% in the fourth quarter of 2025, reflecting continued repricing of certificates of deposits in the first quarter of 2026.

Noninterest income totaled $2.0 million for the first quarter of 2026, a decrease of $328 thousand, or 14.3%, from the fourth quarter of 2025, primarily attributable to a decrease in gain on sale of government guaranteed loans ("GGL"), net of other categories within noninterest income. Noninterest expense totaled $13.0 million for the first quarter of 2026, an increase of $782 thousand, or 6.4%, from the fourth quarter of 2025. This increase was primarily due to higher salaries and employee benefits, other professional services, and other noninterest expense. The Company continues to focus on organic growth and expansion through banker recruiting across the franchise.

The Company’s effective tax rate for the first quarter of 2026 was 23.6%, compared to 18.3% for the fourth quarter of 2025, and 23.4% for the first quarter of 2025. The increase in effective tax rate from the fourth quarter of 2025 was primarily due to a lower recognition of benefits from tax credits in the first quarter of 2026.

Balance Sheet Trends

Total assets were $2.35 billion at March 31, 2026, an increase of approximately $42.0 million, or 1.8%, from $2.31 billion at December 31, 2025. Loans held for sale ("LHFS") were $202.6 million at March 31, 2026, an increase of $31.7 million, or 18.5%, from $170.9 million at December 31, 2025.

Noninterest-bearing deposits were $311.1 million at March 31, 2026, or 15.1% of total deposits, compared to $312.3 million, or 15.7% of total deposits, at December 31, 2025. Brokered certificates of deposit, a component of time deposits, were $258.6 million at March 31, 2026, as compared to $307.0 million at December 31, 2025, a decrease of $48.4 million, or 15.8%.

Credit Quality

During the first quarter of 2026, the Company recorded a provision for credit losses of $382 thousand, compared to $1.2 million and $629 thousand during the fourth and first quarters of 2025, respectively. The provision expense recorded during the first quarter of 2026 was due to loan production and mix and economic factors, offset with other changes in loss rates. The Company's annualized net charge-offs to average LHFI ratio was 0.01% for the first quarter of 2026 as compared to 0.00% and 0.00% during the fourth and first quarters of 2025, respectively.

Nonperforming assets totaled $18.2 million, or 0.77% of total assets, at March 31, 2026 compared to $18.3 million, or 0.79% of total assets at December 31, 2025. The $123 thousand decrease in nonperforming assets at March 31, 2026 from December 31, 2025 was primarily due to payments on nonaccrual assets, offset with additions to nonaccrual assets. Adjusted nonperforming assets³, which excludes the guaranteed portions of nonaccrual loans, was $14.5 million, or 0.62% of total assets, at March 31, 2026 compared to $14.2 million, or 0.62% of total assets, at December 31, 2025.

Non-GAAP Financial Measures

The measures entitled return on average tangible common shareholders' equity, tangible book value per common share, tangible common equity, tangible assets, adjusted nonperforming assets to total assets, adjusted nonperforming assets, pre-tax, pre-provision net revenue ("PPNR"), tangible common equity to tangible assets and core deposits are not measures recognized under accounting principles generally accepted in the United States of America (“GAAP”) and therefore are considered non-GAAP financial measures. The most comparable GAAP measures to these measures are return on average shareholders’ equity, book value per share, total shareholders’ equity, total assets, total nonperforming assets to total assets, total nonperforming assets, net income, total common equity to total assets, and total deposits, respectively.

Management believes that these non-GAAP financial measures and the information they provide are useful to investors since these measures permit investors to view the Company’s performance using the same tools that management uses to evaluate the Company’s past performance and prospects for future performance. While management believes that these non-GAAP financial measures are useful in evaluating our performance, this information should be considered as supplemental and not as a substitute for or superior to the related financial information prepared in accordance with GAAP. Additionally, these non-GAAP financial measures should be considered as additional views of the way the Company’s financial measures are affected by significant items and other factors, and since they are not required to be uniformly applied, they may not be comparable to other similarly titled measures at other companies.
