As a result, we are pleased to share our first quarter operating results. The quarter represents a solid start to a new year and exciting opportunities for our future,” said James P. Helt, ACNB Corporation President and Chief Executive Officer.

“We are pleased and excited to welcome Traditions Bancorp, Inc. shareholders, employees and customers to the ACNB family as we successfully completed our acquisition in the first quarter. In addition, at the close of the acquisition, three former Traditions directors, Eugene J, Draganosky, Elizabeth F. Carson and John M.

We believe this combination brings together organizations that are unified by a shared vision to banking to create an even stronger community bank and substantially enhance our presence in York and Lancaster counties.”

Mr. Helt continued, “We are cautiously optimistic for the remainder of 2025 in spite of the uncertain economic headwinds as a result of ongoing tariff turmoil. We are not only focused on the challenges, but also the exciting opportunities that lie ahead and are fully committed to the continued growth and profitability of ACNB Corporation and to enhancing long term shareholder value.”

Acquisition Update

During the first quarter of 2025, ACNB acquired Traditions, holding company for Traditions Bank, York, Pennsylvania. Traditions was merged with and into a wholly-owned subsidiary of ACNB Corporation immediately followed by the merger of Traditions Bank with and into ACNB Bank effective February 1, 2025. ACNB Bank is operating the former Traditions Bank offices as “Traditions Bank, A Division of ACNB Bank”. The acquisition method of accounting was used to account for the acquisition. ACNB recorded the assets and liabilities of Traditions at their respective fair values as of February 1, 2025. The transaction was valued at approximately $83.8 million and substantially expanded ACNB’s footprint in the York and Lancaster, Pennsylvania markets. Traditions contributed, after acquisition accounting adjustments, $877.7 million in assets, $648.5 million in loans and $741.5 million in deposits at the Acquisition date. The excess of the merger consideration over the fair value of Traditions assets acquired and liabilities assumed resulted in goodwill of $20.3 million.

As of March 31, 2025, total acquisition accounting adjustments on loans were $24.5 million. The majority of the loan acquisition accounting adjustments are expected to accrete back through as income as loans pay off or mature. Total acquisition accounting adjustments on time deposits were $226 thousand as of March 31, 2025. The acquisition accounting adjustments on time deposits are expected to amortize as an expense over the life of the time deposits. The core deposit intangible was $18.3 million as of March 31, 2025.

¹ Non-GAAP financial measure. Please refer to the calculation on the page titled “Non-GAAP Reconciliation” at the end of this document.

The core deposit intangible is expected to amortize as an expense over an expected life of 10 years using sum of the year’s digits method. The acquisition accounting adjustments are subject to refinement for up to one year from the acquisition date as allowable by U.S. Generally Accepted Accounting Principles (“GAAP”).

ACNB recorded an allowance for credit losses of $6.9 million at the Acquisition date, comprised of $5.5 million for non-PCD loans, which was recognized through the provision for credit losses, and $1.5 million for accruing PCD loans, which was recognized as an acquisition accounting adjustment to the amortized cost basis of the acquired loans.

ACNB completed, following the Acquisition date, the sale of approximately $98.0 million of Traditions’ investments with a yield of 5.03%. With the proceeds from the sale, ACNB paid off $40.2 million of Federal Home Loan Bank (“FHLB”) borrowings with a cost of 4.73% and invested the remainder of the proceeds into investment securities with a yield of 5.07%.
