The financial results for the three months ended December 31, 2025 were impacted by an after-tax loss of $2.8 million due to the repositioning of the investment securities portfolio as announced on Form 8-K on December 5, 2025 and, to a lesser extent, after-tax merger-related expenses of $447 thousand.

Net Interest Income and Margin

Net interest income for the three months ended March 31, 2026 totaled $32.5 million, an increase of $5.4 million from the three months ended March 31, 2025 and a decrease of $336 thousand from the three months ended December 31, 2025. The FTE net interest margin for the three months ended March 31, 2026 was 4.46%, a 39 basis points increase from the three months ended March 31, 2025 and a 10 basis points increase from the three months ended December 31, 2025.

The increase in net interest income and FTE net interest margin compared to the three months ended March 31, 2025 was driven primarily by the balance sheet restructuring completed during the three months ended December 31, 2025, the Acquisition and new loans and securities funded during the quarter at higher rates than those that paid off or matured. The FTE yield on total investment securities was 3.66% for the three months ended March 31, 2026, an increase of 75 basis points compared to the three months ended March 31, 2025. Increases in average balances and yields compared to the same period of the prior year were driven primarily by the impact of the Acquisition. For the three months ended March 31, 2026, total average loans increased $208.6 million, or 9.8%, compared to the three months ended March 31, 2025. The FTE yield on total loans was 6.35% for the three months ended March 31, 2026, an increase of 27 basis points compared to the three months ended March 31, 2025. For the three months ended March 31, 2026, total average interest-bearing deposits increased $151.8 million, or 8.6%, from the three months ended March 31, 2025. The average rate paid on interest-bearing deposits was 1.35% for the three months ended March 31, 2026, a decrease of 3 basis points from the three months ended March 31, 2025. For the three months ended March 31, 2026, total average noninterest-bearing demand deposits increased $41.6 million, or 8.1%, from the three months ended March 31, 2025 driven primarily by the Acquisition and promotional incentives on commercial checking accounts.

The decrease in net interest income compared to the three months ended December 31, 2025 was driven primarily by fewer days of interest accruals and, to a lesser extent, the decrease in total average earning assets of $27.6 million, or 0.9%. The decrease in interest-earning assets was driven primarily by lower invested cash balances due to the seasonal decline in the balance of one commercial deposit account as well as lower average loans held for sale and loans held for investment. While average loan balances declined, total loans increased as a result of loan closings that occurred at the end of the three months ended March 31, 2026. The FTE net interest margin increased 10 basis points compared to the three months ended December 31, 2025 driven primarily by the impact of the balance sheet restructuring completed during the three months ended December 31, 2025. The FTE yield on total investment securities increased 49 basis points compared to the three months ended December 31, 2025. For the three months ended March 31, 2026, total average interest-bearing deposits increased $3.4 million, or 0.2%, from the three months ended December 31, 2025. The average rate paid on interest-bearing deposits decreased 1 basis point from the three months ended December 31, 2025. The accretion impact of acquisition accounting adjustments on loans and deposits from the Acquisition was $1.9 million, $1.5 million and $1.9 million for the three months ended March 31, 2026, the three months ended March 31, 2025 and the three months ended December 31, 2025, respectively.

Noninterest Income

Noninterest income for the three months ended March 31, 2026 was $8.3 million, an increase of $1.1 million and $3.9 million from the three months ended March 31, 2025 and the three months ended December 31, 2025, respectively. The increase compared to the three months ended March 31, 2025 was driven primarily by the Acquisition and compared to the three months ended December 31, 2025 was driven primarily by the repositioning of the investment securities portfolio, which generated a $3.6 million pre-tax loss on the sale of investment securities. Gain from mortgage loans held for sale for the three months ended March 31, 2026 was $1.2 million, an increase of $371 thousand from the three months ended March 31, 2025 driven primarily by the Acquisition. Earnings on investment in bank-owned life insurance was $737 thousand for the three months ended March 31, 2026, a $157 thousand increase from the three months ended March 31, 2025 driven primarily by the purchase of new policies in the third quarter of 2025 and the Acquisition. The sale of a building contributed a $177 thousand gain on assets held for sale and a death benefit contributed a $174 thousand gain on life insurance proceeds for the three months ended March 31, 2026. Service charges on deposits totaled $1.2 million, a $141 thousand increase compared to the three months ended March 31, 2025 driven primarily by the Acquisition. Wealth management income was $1.2 million, a $100 thousand increase compared to the three months ended March 31, 2025 driven primarily by growth of fee-based assets under management/ administration. Other totaled $489 thousand, a $140 thousand increase primarily attributable to a gain on a loan sale compared to the three months ended March 31, 2025.

Excluding the net gains (losses) on sales or calls of investment securities, the increase in noninterest income compared to the three months ended December 31, 2025 was impacted by a gain on life insurance proceeds of $174 thousand and the gain on assets held for sale of $177 thousand. Insurance commissions were $2.1 million, a $246 thousand increase compared to the three months ended December 31, 2025 driven primarily by higher renewals and the policy cancellation of a customer in the prior quarter. Partially offsetting the increase in noninterest income were lower gains from mortgage loans held for sale, service charges on deposits and ATM debit charges primarily driven by seasonality.

Noninterest Expense

Noninterest expense for the three months ended March 31, 2026 was $23.6 million, a decrease of $5.7 million from the three months ended March 31, 2025, driven primarily by the Acquisition, and an increase of $162 thousand from the three months ended December 31, 2025. Merger-related expenses totaled $8.0 million for the three months ended March 31, 2025 and $575 thousand for the three months ended December 31, 2025 compared to no merger-related expenses for the three months ended March 31, 2026.

The increase from the three months ended March 31, 2025 was driven primarily by additional employees attributable to the Acquisition as well as merit increases. The increase from the three months ended December 31, 2025 was driven primarily by seasonal expenses of $600 thousand related to incentive stock awards and $270 thousand related to ACNB's liability for unused vacation days, which was driven primarily by headcount increases due to the Acquisition.

Equipment expense increased $320 thousand and $244 thousand from the three months ended March 31, 2025 and the three months ended December 31, 2025, respectively, driven primarily by the Acquisition and the implementation of additional products into our core processing system compared to the three months ended March 31, 2025 and higher core processing and hardware expense compared to the three months ended December 31, 2025. Net occupancy for the three months ended March 31, 2026 increased $91 thousand and $292 thousand compared to the three months ended March 31, 2025 and the three months ended December 31, 2025, respectively. The increase compared to the three months ended March 31, 2025 was driven primarily by the Acquisition, and the increase compared to the three months ended December 31, 2025 was driven primarily by seasonally higher snow removal and utility expenses.

Professional services increased $101 thousand and decreased $74 thousand compared to the three months ended March 31, 2025 and the three months ended December 31, 2025, respectively. The increase compared to the three months ended March 31, 2025 was driven primarily by the higher professional services for software integration and legal fees, and the decrease from the three months ended December 31, 2025 was driven primarily by higher consulting fees in 2025. Intangible assets amortization increased $199 thousand compared to the three months ended March 31, 2025 and decreased $74 thousand compared to the three months ended December 31, 2025. The increase was a result of the Acquisition and the decrease was a result of normal attrition.

The increase from the three months ended March 31, 2025 was driven primarily by higher internet banking expenses and supplies and postage, and the decrease was driven primarily by a $475 thousand write-off of legacy accounts receivable at the insurance subsidiary and higher mortgage underwriting and software expenses during the three months ended December 31, 2025.

Loans and Asset Quality

Total loans outstanding were $2.35 billion at March 31, 2026, an increase of $18.7 million from December 31, 2025 and an increase of $27.0 million from March 31, 2025. The increase compared to December 31, 2025 was driven primarily by growth in the commercial real estate portfolio and was partially offset by a decrease in real estate construction. The growth in commercial real estate was spread across a variety of industries, including non-owner occupied apartment complex, owner occupied and non-owner occupied farming, non-owner occupied warehouse and owner occupied office complex categories. The allowance for credit losses was $23.6 million at March 31, 2026, a decrease of $57 thousand compared to December 31, 2025 and a decrease of $1.0 million compared to March 31, 2025. The decrease compared to December 31, 2025 was driven primarily by the movement of higher risk rated construction loans to lower risk rated commercial real estate loans and the paydowns of loans with a specific reserve partially offset by loan growth. The decrease compared to March 31, 2025 was driven primarily by the incorporation of post-COVID lower credit loss history in the bank's allowance for credit losses model. Total non-performing loans to total loans, net of unearned income, decreased to 0.41% as of March 31, 2026, from 0.46% and 0.43% at December 31, 2025 and March 31, 2025, respectively. The decreases from December 31, 2025 and March 31, 2025 were driven by payments received on nonperforming loans.

Deposits and Borrowings

Total deposits were $2.53 billion at March 31, 2026, an increase of $75.6 million from December 31, 2025 and a decrease of $14.2 million from March 31, 2025. Included in total deposits at March 31, 2026 were $576.1 million of noninterest-bearing deposits, which increased $22.2 million and $13.4 million from December 31, 2025 and March 31, 2025, respectively, driven primarily by growth in commercial balances due to promotional incentives on commercial checking accounts. Total interest-bearing deposits were $1.95 billion at March 31, 2026, an increase of $53.4 million from December 31, 2025 and a decrease of $27.6 million from March 31, 2025. Money markets, included in interest-bearing deposits, increased $11.2 million since December 31, 2025 and decreased $52.7 million since March 31, 2025. The increase in money market deposits from December 31, 2025 was driven primarily by growth in balances of both consumer and commercial accounts and the decrease from March 31, 2025 was driven primarily by attrition of higher cost money market deposits from the Acquisition. Time deposits increased $35.6 million and $11.4 million since December 31, 2025 and March 31, 2025, respectively. Included in time deposits were $89.1 million brokered time deposits, an increase of $30.0 million from December 31, 2025 and $35.0 million from March 31, 2025, respectively.

Total borrowings were $279.2 million at March 31, 2026, a decrease of $40.9 million and $20.3 million compared to December 31, 2025 and March 31, 2025, respectively.

Total stockholders' equity was $425.5 million at March 31, 2026 compared to $420.0 million at December 31, 2025 and $386.9 million at March 31, 2025. The increase at March 31, 2026 compared to December 31, 2025 was driven primarily by net income of $13.7 million partially offset by dividends paid of $3.9 million, common stock repurchases of $3.6 million, and a $1.3 million change in unrealized losses in available for sale investment securities. The increase at March 31, 2026 compared to March 31, 2025 was driven primarily by growth in retained earnings and a change in unrealized losses in available for sale investment securities. Tangible book value1 per share was $32.99, $32.22 and $28.23 at March 31, 2026, December 31, 2025 and March 31, 2025, respectively.
