There are no easy answers to this key question, but one reliable measure that can help investors address this is the company's earnings outlook. Not only does this include current consensus earnings expectations for the coming quarter(s), but also how these expectations have changed lately. Empirical research shows a strong correlation between near-term stock movements and trends in earnings estimate revisions. Investors can track such revisions by themselves or rely on a tried-and-tested rating tool like the Zacks Rank, which has an impressive track record of harnessing the power of earnings estimate revisions. Ahead of this earnings release, the estimate revisions trend for ACNB was mixed. While the magnitude and direction of estimate revisions could change following the company's just-released earnings report, the current status translates into a Zacks Rank #3 (Hold) for the stock. So, the shares are expected to perform in line with the market in the near future. You can see the complete list of today's Zacks #1 Rank (Strong Buy) stocks here.

ACNB’s financial results for the three months ended March 31, 2025 were impacted by two discrete items that were related to the acquisition of Traditions Bancorp, Inc. which was completed on February 1, 2025 (“Acquisition”): a provision for credit losses on non-purchase credit deteriorated (“PCD”) loans of $4.2 million, net of taxes, and merger-related expenses, net of taxes, totaling $6.2 million. Financial results for the three months ended March 31, 2025 include ACNB’s standalone results for the month of January 2025. 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. 2026 First Quarter Highlights Return on average assets was 1.71% and return on average equity was 12.97% for the three months ended March 31, 2026 Fully taxable equivalent (“FTE”) net interest margin was 4.46% for the three months ended March 31, 2026 compared to 4.36% for the three months ended December 31, 2025 and 4.07% for the three months ended March 31, 2025 Total loans outstanding were $2.35 billion at March 31, 2026, an increase of 0.8% from December 31, 2025; annualized growth of 3.3% Total noninterest-bearing deposits were $576.1 million at March 31, 2026, an increase of 4.0% from December 31, 2025; annualized growth of 16.3% Total non-performing loans to total loans, net of unearned income, was 0.41% at March 31, 2026 compared to 0.46% at December 31, 2025 and 0.43% at March 31, 2025 Net recoveries to average loans outstanding were 0.00% for the three months ended March 31, 2026 compared to net charge-offs of 0.02% for the three months ended December 31, 2025 and net charge-offs of 0.01% for the three months ended March 31, 2025 Tangible common equity to tangible assets ratio1 of 10.67% at March 31, 2026 compared to 10.60% at December 31, 2025 and 9.33% at March 31, 2025 ACNB repurchased 73,972 shares of ACNB common stock in open market transactions for the three months ended March 31, 2026 at a weighted average price of $47.54 per share. There are 123,099 shares remaining in the current plan “We are pleased to report a strong start to 2026, highlighted by solid profitability, stable asset quality, and continued balance sheet growth. Our results reflect the strength of our core relationship banking strategy, disciplined expense management, and consistent execution across the franchise.” said James P. Helt, ACNB Corporation President and Chief Executive Officer. “Loan growth was healthy during the quarter, supported by a solid pipeline and continued demand across our markets, while deposit growth remained robust and well-balanced, reinforcing our strong liquidity position. Importantly, credit quality metrics remained stable, with low levels of non-performing assets and net charge-offs, underscoring the effectiveness of our conservative underwriting approach.” Mr. Helt continued, “We also maintained strong capital levels, providing both financial flexibility and a solid foundation to support future growth. As we move further into 2026, we remain focused on delivering sustainable earnings, maintaining disciplined risk management, and creating long-term value for our shareholders.” 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.

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 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.

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.

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.

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.

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.

Investors can track such revisions by themselves or rely on a tried-and-tested rating tool like the Zacks Rank, which has an impressive track record of harnessing the power of earnings estimate revisions.

So, the shares are expected to perform in line with the market in the near future. You can see the complete list of today's Zacks #1 Rank (Strong Buy) stocks here.

Thanks to the dedication of our entire team, we achieved our financial metrics that we originally presented at the time of the acquisition.” said James P. Helt, ACNB Corporation President and Chief Executive Officer. “Our continued focus on community banking principles centered on customer relationships has produced a record year of earnings for the Corporation. The Corporation’s credit metrics and capital positions remain strong.
