ITEM 1 — BUSINESS
ACNB CORPORATION
ACNB Corporation, headquartered in Gettysburg, Pennsylvania, is the financial holding company for the wholly-owned subsidiaries of ACNB Bank, Gettysburg, Pennsylvania, and ACNB Insurance Services, Westminster, Maryland. Originally founded in 1857, ACNB Bank serves its marketplace with banking, mortgage and wealth management services, including trust and retail brokerage, via a network of 33 community banking offices and two loan offices located in the Pennsylvania counties of Adams, Berks, Cumberland, Franklin, Lancaster and York and the Maryland counties of Baltimore, Carroll and Frederick. ACNB Insurance Services, the Corporation’s insurance subsidiary, is a full-service agency licensed to do business in 46 states. The agency offers a broad range of property, casualty, health, life and disability insurance serving personal and commercial clients through office locations in Westminster, Maryland, and Gettysburg, Pennsylvania.
ACNB Corporation was formed in 1982, and became the bank holding company for ACNB Bank (formerly Adams County National Bank) in 1983. On July 1, 2017, ACNB Corporation completed the acquisition of New Windsor Bancorp, Inc. and its wholly-owned subsidiary, New Windsor State Bank, a Maryland state-chartered, FDIC-insured community bank headquartered in Taneytown, Maryland. On January 11, 2020, ACNB completed its acquisition of Frederick County Bancorp, Inc. and its wholly-owned subsidiary, Frederick County Bank, a Maryland state-chartered, FDIC-insured community bank headquartered in Frederick, Maryland. Effective February 1, 2025, ACNB closed the acquisition of Traditions Bancorp, Inc., 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. ACNB Bank is operating the former Traditions Bank offices as “Traditions Bank, A Division of ACNB Bank”. Traditions Bank operated eight community banking offices in South Central Pennsylvania which were included in the Acquisition. In April 2025, ACNB consolidated two of the eight Traditions Bank offices into nearby ACNB Bank offices.
The Corporation purchased its insurance subsidiary, ACNB Insurance Services (formerly Russell Insurance Group, Inc.) in 2005. On February 28, 2022, ACNB Insurance Services, completed the acquisition of the business and assets of Hockley & O’Donnell, located in Gettysburg, Pennsylvania.
ACNB’s major source of unconsolidated operating funds is dividends that it receives from its subsidiaries. ACNB’s unconsolidated expenses consist principally of interest expense on long-term borrowings and general expenses related to corporate governance. Dividends that ACNB pays to stockholders consist primarily of dividends declared and paid to ACNB by its subsidiary bank, ACNB Bank.
ACNB and its subsidiaries are not dependent upon a single customer or a small number of customers, the loss of which would have a material adverse effect on the Corporation. ACNB does not depend on foreign sources of funds, nor does it make foreign loans.
The common stock of ACNB is listed on The NASDAQ Capital Market under the symbol ACNB.
BANKING SUBSIDIARY
ACNB Bank
ACNB Bank is a full-service commercial bank operating under charter from the Pennsylvania Department of Banking and Securities. The Bank’s principal Market Areas include Adams County, Pennsylvania, and its surrounding areas in South-central Pennsylvania, as well as Carroll and Frederick Counties in Northern Maryland. This geographic area depends on agriculture, industry, tourism, education and healthcare, as well as local governments, to provide employment for its residents. No single sector dominates the area’s economy. At December 31, 2025, ACNB Bank had total assets of $3.21 billion, total loans, net of unearned income, of $2.33 billion, total deposits of $2.48 billion, and total equity capital of $398.3 million. In October 2010, the Bank converted from a national banking association to a Pennsylvania state-chartered bank and trust company.
The main community banking office of the Bank is located at 16 Lincoln Square, Gettysburg, Pennsylvania. The Bank has a total of 33 community banking offices. The Bank serves its local marketplace in Pennsylvania through 24 community banking offices, including 10 offices in Adams County, nine offices in York County, one office in Cumberland County, one in Franklin County, and two offices and a limited-service office in Lancaster County.

This third-party provider is a broker/dealer, unaffiliated with the Bank or ACNB Wealth Management.

HUMAN CAPITAL
Workforce Composition and Demographics
As of December 31, 2025, ACNB had 501 full-time and 36 part-time employees. None of these employees are represented by a collective bargaining agreement, and ACNB believes it enjoys good relations with its personnel. As of December 31, 2025, approximately 66% of ACNB’s workforce was female and 34% were male. The average tenure of ACNB employees is approximately nine years.
ACNB believes that it is critically important that its employee base reflects the communities that we serve. We work hard to recruit and retain the best talent to meet ACNB customers’ needs, using multiple sourcing methods to ensure we attract the most diverse and qualified candidate pool.
Talent Development and Training
The growth and development of ACNB employees is encouraged and supported. Continuous learning and career development is reinforced through ongoing performance and development conversations with employees, tuition reimbursement program, leadership development opportunities, internally-created training programs, including comprehensive compliance and community banking training. New community banking employees attend two weeks of training onsite, with an additional week of mentoring support on the job. Training opportunities are available both online and in-person, and all employees have online access to courses for professional development provided by a third party.
Employee evaluations are conducted on at least an annual basis. Those evaluations focus on job performance against job specific and organizational competencies, and employee and career development. In addition, we monitor employee engagement through periodic employee surveys followed by a thorough action planning process.
7
Benefits and Wellness
Work-life balance and the safety, health and wellness of employees are top priorities. The Company balances hybrid/remote work while maintaining successful operations. Currently, many of ACNB employees effectively work a hybrid schedule from ACNB offices and remote locations. Employees are continually introduced to wellness initiatives, to reinforce the importance of overall health and well-being. An Employee Assistance Program offers free, confidential counseling services to all employees.
Talent Attraction and Retention
Competitive compensation is offered to support ACNB employee recruitment and retention efforts. Compensation packages include a market-competitive salary, healthcare and retirement benefits, paid time off, 12 paid holidays, and may also include bonuses or sales commissions and short-term and long-term equity incentives. We also offer an internship program to attract and develop future talent.
Culture and Engagement
The Company deploys numerous methods to foster employee engagement and connection, including regular company-wide video calls, bi-monthly service recognition breakfasts that provide connection and discussion with executive leaders, leadership visits and recognition on Employee Appreciation Day, community involvement events, and an annual picnic for all employees to attend.
Community Involvement
ACNB is dedicated to supporting charitable community organizations within the communities it serves. Employees are encouraged to participate in various community events such as parades, walks and 5k runs, farm shows, fund raising events and community donation drives. In 2025, employees supported over 160 community organizations by collectively contributing more than 4,000 volunteer hours in the Company’s Market Areas.
MARKET AREA ECONOMIC FEATURES AND CONDITIONS
ACNB Corporation’s headquarters is in Gettysburg, Pennsylvania. A material amount of land surrounding Gettysburg, Pennsylvania, is under the control of the National Park Service, limiting certain types of development. The Corporation’s major operations are in Adams County, Pennsylvania, and the surrounding areas in South-central Pennsylvania, as well as all of Carroll and Frederick Counties in Northern Maryland. This geographic area depends on agriculture, industry, tourism, education, and healthcare, as well as local governments, to provide employment for its residents. No single sector dominates the area’s economy. Unemployment figures in the subsidiary Bank’s market have been better than those for Pennsylvania and Maryland and the United States. Per capita and household incomes are generally under Pennsylvania averages. The unemployment rate during 2025 averaged 3.6% in the Bank’s nine-county market area, while it averaged 3.9% overall in Pennsylvania and Maryland, and 4.3% in the United States.
COMPETITION
The financial services industry in ACNB’s Market Area is highly competitive, including competition for similar products and services from commercial banks, thrifts, credit unions, finance and mortgage companies, and other nonbank providers of financial services. Several of ACNB’s competitors have legal lending limits that exceed those of ACNB’s subsidiary bank, as well as funding sources in the capital markets that exceed ACNB’s availability. The high level of competition has resulted from changes in the legal and regulatory environment, as well as from the economic climate, customer expectations, and service alternatives via the internet.
SUPERVISION AND REGULATION
Regulation of Bank Holding Company and Subsidiaries
BANK HOLDING COMPANY ACT OF 1956 — ACNB is a financial holding company and is subject to the regulations of the Board of Governors of the Federal Reserve System under the Bank Holding Company Act of 1956. Bank holding companies are required to file periodic reports with and are subject to examination by the Federal Reserve.
The Federal Reserve has issued regulations under the Bank Holding Company Act that require a financial holding company to serve as a source of financial and managerial strength to its subsidiary bank. As a result, the Federal Reserve may require ACNB to stand ready to use its resources to provide adequate capital funds to the Bank during periods of financial stress or adversity. In addition, the Federal Reserve may require a financial holding company to end a nonbanking business if the
8
nonbanking business constitutes a serious risk to the financial soundness and stability of any banking subsidiary of the financial holding company.
The Bank Holding Company Act prohibits ACNB from acquiring direct or indirect control of more than 5% of the outstanding voting stock of any bank, or substantially all of the assets of any bank, or merging with another bank holding company, without the prior approval of the Federal Reserve. The Bank Holding Company Act allows interstate bank acquisitions and interstate branching by acquisition and consolidation in those states that had not elected to opt out by the required deadline. The Pennsylvania Department of Banking and Securities also must approve any similar consolidation. Pennsylvania law permits Pennsylvania financial holding companies to control an unlimited number of banks.
Further, the Bank Holding Company Act restricts ACNB’s nonbanking activities to those that are determined by the Federal Reserve Board to be financial in nature, incidental to such financial activity, or complementary to a financial activity. The Bank Holding Company Act does not place territorial restrictions on the activities of nonbanking subsidiaries of financial holding companies.
GRAMM-LEACH-BLILEY ACT OF 1999 — The Gramm-Leach-Bliley Act of 1999 eliminated many of the restrictions placed on the activities of bank holding companies that become financial holding companies. Among other things, the GLBA repealed certain Glass-Steagall Act restrictions on affiliations between banks and securities firms, and amended the Bank Holding Company Act to permit bank holding companies that are financial holding companies to engage in activities, and acquire companies engaged in activities, that are: financial in nature (including insurance underwriting, insurance company portfolio investment, financial advisory, securities underwriting, dealing and market-making, and merchant banking activities); incidental to financial activities; or, complementary to financial activities if the Federal Reserve determines that they pose no substantial risk to the safety or soundness of depository institutions or the financial system in general.
REGULATION W — Transactions between a bank and its “affiliates” are quantitatively and qualitatively restricted under the Federal Reserve Act. The Federal Deposit Insurance Act applies Sections 23A and 23B to insured nonmember banks in the same manner and to the same extent as if they were members of the Federal Reserve System. The Federal Reserve has also issued Regulation W, which codifies prior regulations under Sections 23A and 23B of the Federal Reserve Act, and interpretative guidance with respect to affiliate transactions. Regulation W incorporates the exemption from the affiliate transaction rules, but expands the exemption to cover the purchase of any type of loan or extension of credit from an affiliate. Affiliates of a bank include, among other entities, the bank’s holding company and companies that are under common control with the bank. ACNB Corporation and ACNB Insurance Services are considered to be affiliates of ACNB Bank.
USA PATRIOT ACT OF 2001 — In October 2001, the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 was enacted in response to the terrorist attacks in New York, Pennsylvania and Washington, D.C., which occurred on September 11, 2001. The USA Patriot Act is intended to strengthen U.S. law enforcement’s and the intelligence communities’ abilities to work cohesively to combat terrorism on a variety of fronts. The impact of the USA Patriot Act on financial institutions of all kinds is significant and wide ranging. The USA Patriot Act contains sweeping anti-money laundering and financial transparency laws and imposes various regulations, including standards for verifying customer identification at account opening, and rules to promote cooperation among financial institutions, regulators and law enforcement entities in identifying parties that may be involved in terrorism or money laundering.
SARBANES-OXLEY ACT OF 2002 — In 2002, the Sarbanes-Oxley Act of 2002 became law. The stated goals of the SOA are to increase corporate responsibility, to provide for enhanced penalties for accounting and auditing improprieties at publicly-traded companies, and to protect investors by improving the accuracy and reliability of corporate disclosures pursuant to the securities law.
The SOA generally applies to all companies, both U.S. and non-U.S., that file or are required to file periodic reports with the SEC under the Exchange Act.
The SOA includes very specific additional disclosure requirements and corporate governance rules, as well as requires the SEC and securities exchanges to adopt extensive additional disclosure, corporate governance, and other related rules. The SOA represents significant federal involvement in matters traditionally left to state regulatory systems, such as the regulation of the accounting profession, and to state corporate law, such as the relationship between a board of directors and management and between a board of directors and its committees.
The SOA addresses, among other matters:
•Audit committees for all reporting companies;
•Certification of financial statements by the chief executive officer and the chief financial officer;
9
•The forfeiture of bonuses or other incentive-based compensation and profits from the sale of an issuer’s securities by directors and senior officers in the twelve-month period following initial publication of any financial statements that later require restatement;
•A prohibition on insider trading during pension plan blackout periods;
•Disclosure of OBS transactions;
•A prohibition on personal loans to directors and officers;
•Expedited filing requirements for SEC Forms 4;
•Disclosure of a code of ethics and filing an SEC Form 8-K for a change or waiver of such code;
•“Real time” filing of periodic reports;
•Formation of a public accounting oversight board;
•Auditor independence; and,
•Increased criminal penalties for violations of securities laws
The SEC has been delegated the task of enacting rules to implement various provisions of the SOA with respect to, among other matters, disclosure in periodic filings pursuant to the Exchange Act.
BANK SECRECY ACT — Under the Bank Secrecy Act, banks and other financial institutions are required to report to the Internal Revenue Service currency transactions of more than $10 thousand or multiple transactions of which a bank is aware in any one day that aggregate in excess of $10 thousand and to report suspicious transactions under specified criteria. Civil and criminal penalties are provided under the BSA for failure to file a required report, for failure to supply information required by the BSA, or for filing a false or fraudulent report.
The Bank Secrecy Act, as amended by the USA Patriot Act, imposes obligations on U.S. financial institutions, including banks and broker-dealer subsidiaries, to implement policies, procedures and controls which are reasonably designed to detect and report instances of money laundering and the financing of terrorism. Financial institutions also are required to respond to requests for information from federal banking agencies and law enforcement agencies. Information sharing among financial institutions for the above purposes is encouraged by an exemption granted to complying financial institutions from the privacy provisions of the GLBA and other privacy laws. Financial institutions that hold correspondent accounts for foreign banks or provide banking services to foreign individuals are required to take measures to avoid dealing with certain foreign individuals or entities, including foreign banks with profiles that raise money laundering concerns and are prohibited from dealing with foreign “shell banks” and persons from jurisdictions of particular concern. The primary federal banking agencies and the Secretary of the Treasury have adopted regulations to implement several of these provisions. Since 2018, the Bank has complied with the new Customer Due Diligence Rule, which clarified and strengthened the existing obligations for identifying new and existing customers and includes risk-based procedures for conducting ongoing customer due diligence. All financial institutions are also required to establish internal anti-money laundering programs. The effectiveness of a financial institution in combating money laundering activities is a factor to be considered in any application submitted by the financial institution under the Bank Merger Act. The Corporation’s banking subsidiary has a BSA and USA Patriot Act compliance program commensurate with its risk profile and appetite.
DODD-FRANK WALL STREET REFORM AND CONSUMER PROTECTION ACT — In 2010, Dodd-Frank was signed into law. Dodd-Frank was intended to affect a fundamental restructuring of federal banking regulation. Among other things, Dodd-Frank created the Financial Stability Oversight Council to identify systemic risks in the financial system and gives federal regulators new authority to take control of and liquidate financial firms. Dodd-Frank additionally created a new independent federal regulator to administer federal consumer protection laws. Dodd-Frank has had and will continue to have a significant impact on ACNB’s business operations as its provisions take effect. It is expected that, as various implementing rules and regulations are released, they will increase ACNB’s operating and compliance costs and could increase the Bank’s interest expense. Among the provisions that are likely to affect ACNB are the following:
Holding Company Capital Requirements
Dodd-Frank requires the Federal Reserve to apply consolidated capital requirements to bank holding companies that are no less stringent than those currently applied to depository institutions. Under these standards, trust preferred securities are excluded from Tier 1 capital unless such securities were issued prior to May 19, 2010, by a bank holding company with less than $15 billion in assets as of December 31, 2009. Dodd-Frank additionally requires that bank regulators issue countercyclical capital requirements so that the required amount of capital increases in times of economic expansion, consistent with safety and
10
soundness. For further information, please refer to Regulatory Capital Requirements in Management’s Discussion and Analysis.
Deposit Insurance
Dodd-Frank permanently increased the maximum deposit insurance amount for banks, savings institutions, and credit unions to $250 thousand per depositor. Dodd-Frank also broadened the base for FDIC insurance assessments. Assessments are now based on the average consolidated total assets less tangible equity capital of a financial institution. Dodd-Frank required the FDIC to increase the reserve ratio of the Deposit Insurance Fund from 1.15% to 1.35% of insured deposits by 2020 and eliminated the requirement that the FDIC pay dividends to insured depository institutions when the reserve ratio exceeds certain thresholds. Dodd-Frank also eliminated the federal statutory prohibition against the payment of interest on business checking accounts.
Corporate Governance
Dodd-Frank requires publicly-traded companies to give stockholders a non-binding vote on executive compensation at least every three years, a non-binding vote regarding the frequency of the vote on executive compensation at least every six years, and a non-binding vote on “golden parachute” payments in connection with approvals of mergers and acquisitions unless previously voted on by stockholders. Additionally, Dodd-Frank directs the federal banking regulators to promulgate rules prohibiting excessive compensation paid to executives of depository institutions and their holding companies with assets in excess of $1 billion, regardless of whether the company is publicly traded. Dodd-Frank also gives the SEC authority to prohibit broker discretionary voting on elections of directors and executive compensation matters.
Prohibition Against Charter Conversions of Troubled Institutions
Dodd-Frank prohibits a depository institution from converting from a state to a federal charter, or vice versa, while it is the subject of a cease and desist order or other formal enforcement action or a memorandum of understanding with respect to a significant supervisory matter unless the appropriate federal banking agency gives notice of the conversion to the federal or state authority that issued the enforcement action and that agency does not object within 30 days. The notice must include a plan to address the significant supervisory matter. The converting institution must also file a copy of the conversion application with its current federal regulator, which must notify the resulting federal regulator of any ongoing supervisory or investigative proceedings that are likely to result in an enforcement action and provide access to all supervisory and investigative information relating thereto.
Interstate Branching
Dodd-Frank authorizes national and state banks to establish branches in other states to the same extent as a bank chartered by that state would be permitted. Previously, banks could only establish branches in other states if the host state expressly permitted out-of-state banks to establish branches in that state. Accordingly, banks are able to enter new markets more freely.
Limits on Interstate Acquisitions and Mergers
Dodd-Frank precludes a bank holding company from engaging in an interstate acquisition—the acquisition of a bank outside its home state—unless the bank holding company is both well capitalized and well managed. Furthermore, a bank may not engage in an interstate merger with another bank headquartered in another state unless the surviving institution will be well capitalized and well managed. The previous standard in both cases was adequately capitalized and adequately managed.
Limits on Interchange Fees
Dodd-Frank amended the Electronic Fund Transfer Act to, among other things, give the Federal Reserve the authority to establish rules regarding interchange fees charged for electronic debit transactions by payment card issuers having assets over $10 billion and to enforce a new statutory requirement that such fees be reasonable and proportional to the actual cost of a transaction to the issuer.
Consumer Financial Protection Bureau
Dodd-Frank created the independent federal agency called the CFPB, which is granted broad rulemaking, supervisory and enforcement powers under various federal consumer financial protection laws, including the Equal Credit Opportunity Act, Truth in Lending Act, Real Estate Settlement Procedures Act, Fair Credit Reporting Act, Fair Debt Collection Act, Consumer Financial Privacy provisions of the Gramm-Leach-Bliley Act, and certain other statutes. The CFPB has examination and primary enforcement authority with respect to depository institutions with $10 billion or more in assets. Smaller institutions are subject to rules promulgated by the CFPB, but continue to be examined and supervised by federal banking regulators for consumer compliance purposes. The CFPB has authority to prevent unfair, deceptive or abusive practices in connection with the offering of consumer financial products. Dodd-Frank authorizes the CFPB to establish certain minimum standards for the
11
origination of residential mortgages including a determination of the borrower’s ability to repay. In addition, Dodd-Frank allows borrowers to raise certain defenses to foreclosure if they receive any loan other than a “qualified mortgage” as defined by the CFPB. Dodd-Frank permits states to adopt consumer protection laws and standards that are more stringent than those adopted at the federal level and, in certain circumstances, permits state attorneys general to enforce compliance with both the state and federal laws and regulations.
ABILITY-TO-REPAY AND QUALIFIED MORTGAGE RULE — Pursuant to Dodd-Frank as highlighted above, the CFPB issued a final rule on January 10, 2013 (effective on January 10, 2014), amending Regulation Z as implemented by the Truth in Lending Act, requiring mortgage lenders to make a reasonable and good faith determination based on verified and documented information that a consumer applying for a mortgage loan has a reasonable ability to repay the loan according to its terms. Mortgage lenders are required to determine the consumer’s ability to repay in one of two ways. The first alternative requires the mortgage lender to consider the following eight underwriting factors when making the credit decision: (1) current or reasonably expected income or assets; (2) current employment status; (3) the monthly payment on the covered transaction; (4) the monthly payment on any simultaneous loan; (5) the monthly payment for mortgage-related obligations; (6) current debt obligations, alimony, and child support; (7) the monthly debt-to-income ratio or residual income; and, (8) credit history. Alternatively, the mortgage lender can originate “qualified mortgages”, which are entitled to a presumption that the creditor making the loan satisfied the ability-to-repay requirements. In general, a “qualified mortgage” is a mortgage loan without negative amortization, interest-only payments, balloon payments, or terms exceeding 30 years. In addition, to be a qualified mortgage, the points and fees paid by a consumer cannot exceed 3% of the total loan amount. Loans which meet these criteria will be considered qualified mortgages and, as a result, generally protect lenders from fines or litigation in the event of foreclosure. Qualified mortgages that are “higher-priced” (e.g., subprime loans) garner a rebuttable presumption of compliance with the ability-to-repay rules, while qualified mortgages that are not “higher-priced” (e.g., prime loans) are given a safe harbor of compliance. The impact of the final rule, and the subsequent amendments thereto, on the Corporation’s lending activities and the Corporation’s statements of income or condition has had little or no impact; however, management will continue to monitor the implementation of the rule for any potential effects on the Corporation’s business.
DEPARTMENT OF DEFENSE MILITARY LENDING RULE — In 2015, the U.S. Department of Defense issued a final rule which restricts pricing and terms of certain credit extended to active-duty military personnel and their families. This rule, which was implemented effective October 3, 2016, caps the interest rate on certain credit extensions to an annual percentage rate of 36% and restricts other fees. The rule requires financial institutions to verify whether customers are military personnel subject to the rule. The impact of this final rule, and any subsequent amendments thereto, on the Corporation’s lending activities and the Corporation’s statements of income or condition has had little or no impact; however, management will continue to monitor the implementation of the rule for any potential effects on the Corporation’s business.
FEDERAL DEPOSIT INSURANCE CORPORATION ACT OF 1991 — Under the Federal Deposit Insurance Corporation Act of 1991, any depository institution, including the subsidiary bank, is prohibited from paying any dividends, making other distributions or paying any management fees if, after such payment, it would fail to satisfy the minimum capital requirement.
FEDERAL RESERVE ACT — A subsidiary bank of a bank holding company is subject to certain restrictions and reporting requirements imposed by the Federal Reserve Act, including:
•Extensions of credit to the bank holding company, its subsidiaries, or principal stockholders;
•Investments in the stock or other securities of the bank holding company or its subsidiaries; and,
•Taking such stock or securities as collateral for loans.
COMMUNITY REINVESTMENT ACT OF 1977 — Under the CRA, the FDIC is required to assess the record of all financial institutions regulated by it to determine if these institutions are meeting the credit needs of the community, including low- and moderate-income neighborhoods, which they serve and to take this record into account in its evaluation of any application made by any of such institutions for, among other things, approval of a branch or other deposit facility, office relocation, merger, or acquisition of bank shares. The Financial Institutions Reform, Recovery and Enforcement Act of 1989 amended the CRA to require, among other things, that the FDIC make publicly available the evaluation of a bank’s record of meeting the credit needs of its entire community, including low- and moderate-income neighborhoods. This evaluation includes a descriptive rating like “outstanding”, “satisfactory”, “needs to improve” or “substantial noncompliance” and a statement describing the basis for the rating. These ratings are publicly disclosed.
12
FEDERAL DEPOSIT INSURANCE CORPORATION IMPROVEMENT ACT OF 1991 — The FDICIA requires that institutions be classified, based on their risk-based capital ratios, into one of five defined categories as follows and as illustrated below: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, or critically undercapitalized.
Total
 Risk-Based
Ratio		Tier 1
Risk-Based
Ratio		Tier 1
Leverage
Ratio		Under a
Capital
Order or
Directive
Capital Category    
Well capitalized≥10.0 %≥8.0 %≥5.0 % NO
Adequately capitalized≥8.0 %≥6.0 %≥4.0 % 
Undercapitalized<8.0 %<6.0 %≥4.0 % 
Significantly undercapitalized<6.0 %<4.0 %<3.0 %  
Critically undercapitalized  <2.0 %  
In the event an institution’s capital deteriorates to the undercapitalized category or below, FDICIA prescribes an increasing amount of regulatory intervention, including the institution of a capital restoration plan and a guarantee of the plan by a parent institution and the placement of a hold on increases in assets, number of branches, or lines of business. If capital reaches the significantly or critically undercapitalized levels, further material restrictions can be imposed, including restrictions on interest payable on accounts, dismissal of management, and, in critically undercapitalized situations, appointment of a receiver. For well capitalized institutions, FDICIA provides authority for regulatory intervention when the institution is deemed to be engaging in unsafe or unsound practices or receives a less than satisfactory examination report rating for asset quality, management, earnings or liquidity. All but well capitalized institutions are prohibited from accepting brokered deposits without prior regulatory approval. Under FDICIA, financial institutions are subject to increased regulatory scrutiny and must comply with certain operational, managerial and compensation standards established by Federal Reserve Board regulations.
In July 2013, the federal banking agencies issued final rules to implement the Basel III regulatory capital reforms and changes required by the Dodd-Frank. The phase-in period for community banking organizations began January 1, 2015, while larger institutions (generally those with assets of $50 billion or more) began compliance on January 1, 2014. The final rules call for the following capital requirements which remain in effect:
•A minimum ratio of common equity Tier 1 capital to total risk-weighted assets of 4.5%
•A minimum ratio of Tier 1 capital to risk-weighted assets of 6.0%
•A minimum ratio of total capital ratio of total capital to total risk-weighted assets of 8.0%
•A minimum leverage ratio of Tier 1 capital to average total consolidated assets of 4.0%
A discussion of how these capital rules affect ACNB Corporation appears under Item 7 — “Management’s Discussion and Analysis of Financial Condition and Results of Operations”.
Dividends
ACNB is a legal entity separate and distinct from its subsidiary bank and insurance agency subsidiary. ACNB’s revenues, on a parent company only basis, result primarily from dividends paid to the Corporation by its subsidiaries. Federal and state laws regulate the payment of dividends by ACNB’s subsidiary bank and state laws effect dividends paid by ACNB’s insurance subsidiary. ACNB’s dividends to stockholders is governed by the Pennsylvania Business Corporation Law. For further information, please refer to Regulation of Bank below and Note 16 — “Regulatory Matters”, to the Consolidated Financial Statements under Part II, Item 8 — “Financial Statements and Supplementary Data”.
Regulation of Bank
The operations of the subsidiary bank are subject to statutes applicable to banks and trust companies chartered under the banking laws of Pennsylvania, to state nonmember banks of the Federal Reserve, and to banks whose deposits are insured by the FDIC. The subsidiary bank’s operations are also subject to regulations of the Pennsylvania Department of Banking and Securities, Federal Reserve, and FDIC.
The Pennsylvania Department of Banking and Securities, which has primary supervisory authority over banks chartered in Pennsylvania, regularly examines banks in such areas as reserves, loans, investments, management practices, and other aspects of operations. The subsidiary bank is also subject to examination and supervision by the FDIC for safety and soundness, as well
13
as consumer compliance. These examinations and supervision are designed for the protection of the subsidiary bank’s depositors rather than ACNB’s stockholders. The subsidiary bank must file quarterly and annual reports to the Federal Financial Institutions Examination Council, or FFIEC.
Monetary and Fiscal Policy
ACNB and its subsidiary bank are affected by the monetary and fiscal policies of government agencies, including the Federal Reserve and FDIC. Through open market securities transactions and changes in its discount rate and reserve requirements, the Board of Governors of the Federal Reserve exerts considerable influence over the cost and availability of funds for lending and investment. The nature and impact of monetary and fiscal policies on future business and earnings of ACNB cannot be predicted at this time. From time to time, various federal and state legislation is proposed that could result in additional regulation of, and restrictions on, the business of ACNB and the subsidiary bank, or otherwise change the business environment. Management cannot predict whether any of this legislation will have a material effect on the business of ACNB.

ACQUISITIONS
ACNB Corporation and its subsidiaries pursue organic and inorganic growth strategies. In furtherance of the inorganic growth strategy, on July 1, 2017, ACNB acquired New Windsor Bancorp, Inc. and its wholly-owned subsidiary, New Windsor State Bank, headquartered in Taneytown, Maryland. Additionally, on January 11, 2020, ACNB acquired Frederick County Bancorp, Inc. and its wholly-owned subsidiary, Frederick County Bank, headquartered in Frederick, Maryland. Effective February 1, 2025, ACNB acquired Traditions Bancorp, Inc., 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. ACNB Bank is operating the former Traditions Bank offices as “Traditions Bank, A Division of ACNB Bank”.
On February 28, 2022, ACNB Insurance Services, the wholly-owned insurance subsidiary of ACNB Corporation, acquired the business and assets of Hockley & O’Donnell, located in Gettysburg, Pennsylvania.
ITEM 1A — RISK FACTORS
CREDIT RISKS
ACNB IS SUBJECT TO INTEREST RATE RISK.
ACNB’s earnings and cash flows are largely dependent upon its net interest income. Net interest income is the difference between interest income earned on interest-earning assets, such as loans and securities, and interest expense paid on interest-bearing liabilities, such as deposits and borrowed funds. Interest rates are highly sensitive to many factors that are beyond ACNB’s control, including general economic conditions and policies of various governmental and regulatory agencies and, in particular, the Board of Governors of the Federal Reserve System. Changes in monetary policy, including changes in interest rates, could influence not only the amount of interest ACNB receives on loans and securities and the amount of interest it pays on deposits and borrowings, but such changes could also affect (i) ACNB’s ability to originate loans and obtain deposits, (ii) the fair value of ACNB’s financial assets and liabilities, and (iii) the average duration of ACNB’s mortgage-backed securities portfolio. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and other investments, ACNB’s net interest income, and therefore earnings, could be adversely affected. Earnings could also be adversely affected if the interest rates received on loans and other investments fall more quickly than the interest rates paid on deposits and other borrowings.
Although management believes it has implemented effective asset and liability management strategies to reduce the potential effects of changes and volatility in interest rates on ACNB’s results of operations, any substantial, unexpected or prolonged change in market interest rates could have a material adverse effect on ACNB’s financial condition and results of operations.
14
ACNB IS SUBJECT TO CREDIT RISK.
As of December 31, 2025, approximately 68% of ACNB’s loan portfolio consisted of commercial real estate loans, commercial and industrial and construction. These types of loans are generally viewed as having more risk of default than residential real estate loans or consumer loans. These types of loans are also typically larger than residential real estate loans and consumer loans. Because ACNB’s loan portfolio contains a significant number of commercial real estate, commercial and industrial and construction loans with relatively large balances, the deterioration of one or a few of these loans could cause a significant increase in non-performing loans. An increase in non-performing loans could result in a net loss of earnings from these loans, an increase in the provision for credit losses, and an increase in loan charge-offs, all of which could have a material adverse effect on ACNB’s financial condition and results of operations.
ACNB IS ALSO SUBJECT TO COMMERCIAL REAL ESTATE VOLATILITY.
The commercial real estate market nationally, regionally, and locally has recently been subject to increased levels of volatility. Many believe that commercial real estate in the commercial office sector is undergoing a fundamental transformation and change that started during the recent pandemic but also continues due to evolving workplace environments. These changes in the marketplace affect the demand for commercial office space which in turn may affect the credit status, profitability, and collectability, of existing and future commercial real estate office sector loans. As explained above in greater detail in the risk factor for Credit Risk, volatility and increases in non-performing loans could have an adverse impact on ACNB’s financial condition and results of operations.
ACNB’S ALLOWANCE FOR CREDIT LOSSES MAY BE INSUFFICIENT.
ACNB maintains an ACL, which is a reserve established through a provision for credit losses charged to expense, that represents management’s best estimate of expected credit losses associated with the Corporation’s financial instruments over the life of those instruments as of the balance sheet date. Management utilizes a variety of inputs in the calculation of its estimate, based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. Management’s use of a third-party service provider which provided historical loss data in the calculation of its CECL provision may not approximate its own historical loss data. Management’s ability to accurately forecast future losses under this methodology may be impaired by significant uncertainties such as:
•Surrounding rapid increases in inflation and interest rates, which have disrupted financial markets and adversely affected commercial real estate and other sectors in the economy.
•Related to the identification of the appropriate economic indicators.
•Related to the data utilized to build models and draw assumptions.
•Limitations related to the different sources of data: internal data, peer data, market data, macroeconomic data, geopolitical data, etc.
•Related to the need to make difficult and complex judgments that are often interrelated.
The allowance, in the judgment of management, is necessary to reserve for expected credit losses and risks inherent in the loan portfolio. The determination of the appropriate level of the ACL inherently involves a high degree of subjectivity and requires ACNB to make significant estimates of current credit risks and future trends, all of which may undergo material changes. Changes in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans, and other factors, both within and outside of ACNB’s control, may require an increase in the ACL. In addition, bank regulatory agencies periodically review ACNB’s ACL and may require an increase in the provision for credit losses or the recognition of further loan charge-offs, based on judgments different than those of management. Further, if charge-offs in future periods exceed the ACL, ACNB will need additional provisions to increase the ACL. Any increases in the ACL will result in a decrease in net income, and possibly capital, and may have a material adverse effect on ACNB’s financial condition and results of operations.
BUSINESS RISKS
COMPETITION FROM OTHER FINANCIAL INSTITUTIONS MAY ADVERSELY AFFECT ACNB’S PROFITABILITY.
ACNB’s banking subsidiary faces substantial competition in originating both commercial and consumer loans. This competition comes principally from other banks, credit unions, mortgage banking companies, and other lenders. Many of its competitors enjoy advantages, including greater financial resources with higher lending limits, wider geographic presence, more
15
aggressive marketing campaign, better brand recognition, more branch office locations, the ability to offer a wider array of services or more favorable pricing alternatives, and lower origination and operating costs. This competition could reduce the Corporation’s net income by decreasing the number and size of loans that its banking subsidiary originates and the interest rates it may charge on these loans.
In attracting business and consumer deposits, its banking subsidiary faces substantial competition from other insured depository institutions such as banks, savings institutions, and credit unions, as well as institutions offering uninsured investment alternatives, including money market funds. These competitors may offer higher interest rates than ACNB, which could decrease the deposits that it attracts or require it to increase its rates to retain existing deposits or attract new deposits. Increased deposit competition could adversely affect the subsidiary’s ability to generate the funds necessary for lending operations. As a result, it may need to seek other sources of funds that may be more expensive to obtain and could increase its cost of funds.
ACNB’s banking subsidiary also competes with nonbank providers of financial services, such as brokerage firms, consumer finance companies, credit unions, insurance companies and agencies, and governmental organizations which may offer more favorable terms. Some of its nonbank competitors are not subject to the same extensive regulations that govern ACNB’s banking operations. As a result, such nonbank competitors may have advantages over ACNB’s banking subsidiary in providing certain products and services. This competition may reduce or limit ACNB’s margins on banking services, reduce its market share, and adversely affect its earnings and financial condition.
THE BASEL III CAPITAL REQUIREMENTS OR OTHER REGULATORY CAPITAL STANDARDS OR CHANGES MAY REQUIRE ACNB TO MAINTAIN HIGHER LEVELS OF CAPITAL, WHICH COULD REDUCE ACNB’S PROFITABILITY.
Basel III targets higher levels of base capital, certain capital buffers, and a migration toward common equity as the key source of regulatory capital. Although the new capital requirements are phased in over future years and may change substantially before final implementation, Basel III signals a growing effort by domestic and international bank regulatory agencies to require financial institutions, including depository institutions, to maintain higher levels of capital. The direction of the Basel III implementation activities or other regulatory standards or changes could require additional capital to support the Corporation’s business risk profile prior to final implementation of the Basel III standards. If ACNB and the subsidiary bank are required to maintain higher levels of capital, ACNB and the subsidiary bank may have fewer opportunities to invest capital into interest-earning assets, which could limit the profitable business operations available to ACNB and the subsidiary bank and adversely impact ACNB’s financial condition and results of operations.
ACNB’S OPERATIONS OF ITS BUSINESS, INCLUDING ITS TRANSACTIONS WITH CUSTOMERS, ARE INCREASINGLY DONE ELECTRONICALLY, AND THIS HAS INCREASED ITS RISKS RELATED TO CYBERSECURITY.
Increasingly, financial transactions are processed electronically, both by ACNB and its customers, via online, mobile, and cloud technologies. Operational systems are progressively becoming cloud-based. Conducting business in this environment depends on secure transmission and storage of data in digital form as well as procedures and systems to prevent or ensure the resiliency against system failures, interruptions or breaches in security. As a result, ACNB is exposed to the risk of cyber-attacks in the normal course of business, which may be perpetrated against ACNB, or its third-party service providers and its customers. Further, ACNB may face unknown or contingent liabilities arising from cybersecurity incidents or data breaches that previously occurred at companies it acquires. Such incidents may not have been discovered, disclosed, or if previously discovered fully remediated before closing, and the acquired company’s representations, warranties, and indemnities may be limited in scope, duration, or recoverability. As a result, ACNB could incur costs or liabilities after an acquisition relating to regulatory investigations, litigation, remediation efforts, reputational harm, or customer and partner claims, which could adversely affect its business, financial condition, and results of operations.
In general, cyber incidents can result from deliberate attacks or unintentional events. ACNB has observed an increased level of attention in the industry focused on cyber-attacks that include, but are not limited to, gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. While ACNB maintains insurance coverage that may, subject to policy terms and conditions including significant self-insured deductibles, cover or ameliorate certain financial aspects of cyber risks, such insurance coverage may be insufficient to cover all losses.
ACNB maintains policies and procedures designed to prevent or limit the effects of possible security breaches of its information systems. However, the techniques used for cyber-attacks are becoming increasingly sophisticated, including the use of AI, and there can be no assurance that preventive and detective measures are fail-safe.
While ACNB has not incurred any material losses related to cyber-attacks, nor is it aware of any specific or threatened material cyber incidents as of the date of this report, it may incur substantial costs and suffer other negative consequences if it falls
16
victim to successful cyber-attacks. Such negative consequences could include remediation costs that may include liability for stolen assets or information and repairing system damage that may have been caused; deploying additional personnel and protection technologies, training employees, and engaging third-party experts and consultants; lost revenues resulting from unauthorized use of proprietary information or the failure to retain or attract customers following an attack; disruption or failures of physical infrastructure, operating systems or networks that support ACNB’s business and customers resulting in the loss of customers and business opportunities; additional regulatory scrutiny and possible regulatory penalties; litigation; and, reputational damage adversely affecting customer or investor confidence.
ACNB’S CONTROLS AND PROCEDURES MAY FAIL OR BE CIRCUMVENTED.
Management regularly reviews and updates ACNB’s internal controls, disclosure controls, and procedures, as well as corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of ACNB’s controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on ACNB’s business, financial condition, and results of operations.
ACNB’S ABILITY TO PAY DIVIDENDS DEPENDS PRIMARILY ON DIVIDENDS FROM ITS BANKING SUBSIDIARY, WHICH ARE SUBJECT TO REGULATORY LIMITS AND THE BANKING SUBSIDIARY PERFORMANCE.
ACNB is a financial holding company and its operations are conducted by its subsidiaries. Its ability to pay dividends depends on its receipt of dividends from its subsidiaries. Dividend payments from its banking subsidiary are subject to legal and regulatory limitations, generally based on net profits and retained earnings, imposed by the various banking regulatory agencies. The ability of its subsidiaries to pay dividends is also subject to their profitability, financial condition, capital expenditures, and other cash flow requirements. There is no assurance that its subsidiaries will be able to pay dividends in the future or that ACNB will generate adequate cash flow to pay dividends in the future. ACNB’s failure to pay dividends on its common stock could have a material adverse effect on the market price of its common stock.
NEW LINES OF BUSINESS OR NEW PRODUCTS AND SERVICES MAY SUBJECT ACNB TO ADDITIONAL RISKS.
From time to time, ACNB may implement new lines of business or offer new products and services within existing lines of business. There are substantial risks and uncertainties associated with these efforts, particularly in instances where the markets are not fully developed. In developing and marketing new lines of business and/or new products and services, ACNB may invest significant time and resources. Initial timetables for the introduction and development of new lines of business and/or new products or services may not be achieved and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives, and shifting market preferences, may also impact the successful implementation of a new line of business and/or a new product or service. Furthermore, any new line of business and/or new product or service could have a significant impact on the effectiveness of ACNB’s system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business and new products or services could have a material adverse effect on ACNB’s business, financial condition, and results of operations.
ACNB MAY NOT BE ABLE TO ATTRACT AND RETAIN SKILLED PEOPLE.
ACNB’s success depends, in large part, on its ability to attract and retain key people. Competition for the best people in most activities engaged in by ACNB can be intense, and ACNB may not be able to hire people or to retain them. The unexpected loss of services of one or more of ACNB’s key personnel could have a material adverse impact on ACNB’s business because the Corporation would no longer have the benefit of their skills, knowledge of ACNB’s market, as well as years of industry experience, and it would be difficult to promptly find qualified replacement personnel.
ACNB IS SUBJECT TO CLAIMS AND LITIGATION PERTAINING TO FIDUCIARY RESPONSIBILITY.
From time to time, customers make claims and take legal action pertaining to ACNB’s performance of its fiduciary responsibilities. Whether customer claims and legal action related to ACNB’s performance of its fiduciary responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to ACNB, they may result in significant financial liability and/or adversely affect the market perception of ACNB and its products and services, as well as impact customer demand for those products and services. Any financial liability or reputation damage could have a material adverse effect on ACNB’s business, which, in turn, could have a material adverse effect on ACNB’s financial condition and results of operations.
17
IF ACNB CONCLUDES THAT THE DECLINE IN VALUE OF ANY OF ITS AFS OR HTM INVESTMENT SECURITIES HAVE CREDIT QUALITY ISSUES, ACNB IS REQUIRED TO WRITE DOWN THE VALUE OF AFS SECURITIES THROUGH A CHARGE TO EARNINGS AND BOOK A RESERVE TO THE ACL FOR HTM SECURITIES.
ACNB reviews its investment securities portfolio at each quarter-end to determine whether the fair value is below the current carrying value. When the fair value of any of its investment securities has declined below its carrying value, ACNB is required to assess whether the decline is an impairment due to credit deterioration. If ACNB determines that the decline in value is impaired due to credit deterioration, it is required to write down the value of AFS securities through a charge to earnings and book a reserve for any HTM securities to the allowance for credit losses. Non-credit related reductions in the value of a security do not require a write down of the value through earnings unless ACNB intends to, or is required to, sell the security. Changes in the expected cash flows related to the credit related piece of the investment of a security in ACNB’s investment portfolio or a prolonged price decline may result in ACNB’s conclusion in future periods that a security is to be deemed impaired, which would require a charge to earnings to write down the security to fair value for AFS securities or book a reserve to the allowance for credit losses for HTM securities. Due to the complexity of the calculations and assumptions used in determining whether an asset is impaired, the impairment disclosed may not accurately reflect the actual impairment in the future.
ACNB IS SUBJECT TO POTENTIAL IMPAIRMENT OF GOODWILL AND INTANGIBLES.
ACNB has certain long-lived assets including purchased intangible assets subject to amortization and associated goodwill assets which are reviewed for impairment annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated undiscounted cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the statement of condition and reported at the lower of the carrying amount or fair value less costs to sell, and are no longer depreciated.
Accounting rules permit an entity to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The goodwill impairment analysis involves comparing the reporting unit’s estimated fair value to its carrying value, including goodwill. If the estimated fair value of the reporting unit exceeds its carrying value, goodwill is considered not to be impaired. If the carrying value of goodwill assigned to the reporting unit exceeds the implied fair value of the goodwill, an impairment charge is recorded for the excess. Subsequent reversal of goodwill impairment losses is not permitted.
Goodwill, which has an indefinite useful life, is evaluated pursuant to ASC Topic 350, Intangibles — Goodwill and Other, for impairment annually and is evaluated for impairment more frequently if events and circumstances indicate that the asset might be impaired. An impairment loss is recognized to the extent that the carrying amount exceeds the asset’s fair value. The goodwill impairment analysis involves comparing the reporting unit’s estimated fair value to its carrying value, including goodwill. If the estimated fair value of the reporting unit exceeds its carrying value, goodwill is considered not to be impaired. If the carrying value of goodwill assigned to the reporting unit exceeds the implied fair value of the goodwill, an impairment charge is recorded for the excess. Subsequent reversal of goodwill impairment losses is not permitted. ACNB performs an annual evaluation to determine if there is goodwill impairment.
ACNB IS SUBJECT TO ENVIRONMENTAL LIABILITY RISK ASSOCIATED WITH LENDING ACTIVITIES.
A significant portion of ACNB’s banking subsidiary loan portfolio is secured by real property. During the ordinary course of business, ACNB may foreclose on and take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If hazardous or toxic substances are found, ACNB may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require ACNB to incur substantial expense and may materially reduce the affected property’s value or limit ACNB’s ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement policies with respect to existing laws may increase ACNB’s exposure to environmental liability. Although ACNB has policies and procedures to perform an environmental review before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on ACNB’s financial condition and results of operations.
ACNB’S COMMUNICATIONS, INFORMATION, AND TECHNOLOGY SYSTEMS MAY EXPERIENCE A FAILURE, INTERRUPTION OR BREACH IN SECURITY.
ACNB relies heavily on communications, information, and technology systems to conduct its business. Any failure, interruption or breach in security of these systems at ACNB, or at its third-party service provider of these systems, could result in the reduced ability to operate effectively; disruption in service to its customers; or corruption, loss or compromise of
18
confidential corporate or customer data. The risks are greater if the issue is extensive, long-lasting, or results in financial losses to its customers. Such failures, interruptions or breaches in security may arise from events such as severe weather, acts of vandalism, telecommunications outages, human error, or cyber-attacks.
These risks also arise to the extent ACNB’s third-party service providers experience failures, interruptions and breaches in security. ACNB is also exposed to the risk of a disruption at a common service provider used by ACNB’s third-party service providers. Even with attempts to diversify the reliance upon any one third-party, ACNB may not be able to mitigate the risk of its vendors’ use of common service providers.
While ACNB has policies and procedures designed to prevent or limit the effect of the failure, interruption or security breach of its communication, information, and technology systems, there can be no assurance that any such failures, interruptions or security breaches will not occur or, if they do occur, that they will be adequately addressed. Although ACNB maintains insurance coverage that may, subject to policy terms and conditions including significant self-insured deductibles, cover or ameliorate certain financial aspects of these risks, such insurance coverage may be insufficient to cover all losses. The occurrence of any failures, interruptions or security breaches of ACNB’s communications, information, and technology systems could damage ACNB’s reputation adversely affecting customer or investor confidence, result in a loss of customer business, subject ACNB to additional regulatory scrutiny and possible regulatory penalties, or expose ACNB to civil litigation and possible financial liability, any of which could have a material adverse effect on ACNB’s financial condition and results of operations.
ACNB MAY USE AI IN ITS BUSINESS, AND CHALLENGES WITH PROPERLY MANAGING ITS USE COULD RESULT IN DISRUPTION OF ITS INTERNAL OPERATIONS, REPUTATIONAL HARM, COMPETITIVE HARM, LEGAL LIABILITY AND ADVERSELY AFFECT ACNB’S RESULTS OF OPERATIONS AND STOCK PRICE.
ACNB may incorporate AI solutions into platforms that deliver products and services to its customers, including solutions developed by third parties whose AI is integrated into its products and services. ACNB’s business could be harmed and it may be exposed to legal liability and reputational risk if the AI it uses is or is alleged to be deficient, inaccurate, or biased because the AI algorithms are flawed, insufficient, of poor quality, or reflect unwanted forms of bias, particularly if third party AI integrated with its platforms produces false or “hallucinatory” inferences.
Data practices by ACNB or others that result in controversy could impair the acceptance of AI, which could undermine the decisions, predictions, or analysis that AI applications produce. ACNB’s customers and potential customers may express adverse opinions concerning its use of AI and machine learning that could result in brand or reputational harm, competitive harm, or legal liability. If ACNB develops Generative AI, its content creation may require additional investment as testing for bias, accuracy and unintended, harmful impact is often complex and may be costly. As a result, ACNB may need to increase the cost of its products and services which may make it less competitive, particularly if its competitors incorporate AI more quickly or successfully.
Governmental bodies have implemented laws and are considering further regulation of AI (including machine learning), which could negatively impact ACNB’s ability to use and develop AI. ACNB is unable to predict how application of existing laws, including federal and state privacy and data protection laws, and adoption of new laws and regulations applicable to AI will affect it but it is likely that compliance with such laws and regulations will increase its compliance costs and such increase may be substantial and adversely affect its results of operations. Furthermore, its use of Generative AI and other forms of AI may expose us to risks relating to intellectual property ownership and licensing rights, including copyright of Generative AI and other AI output as these issues have not been fully interpreted by federal courts or been fully addressed by federal or state legislation or regulations.
STRATEGIC AND EXTERNAL RISKS
ACNB’S PROFITABILITY DEPENDS SIGNIFICANTLY ON ECONOMIC CONDITIONS IN ITS MARKET AREA AND IN THE COMMONWEALTH OF PENNSYLVANIA AND THE STATE OF MARYLAND.
ACNB’s success depends primarily on the general economic conditions of the Commonwealth of Pennsylvania, the State of Maryland, and the specific local markets in which ACNB operates. Unlike larger national or other regional banks that are more geographically diversified, ACNB provides banking and financial services to customers primarily in the South-central Pennsylvania and Northern Maryland region of the country. The local economic conditions in these areas have a significant impact on the demand for ACNB’s products and services, as well as the ability of ACNB’s customers to repay loans, the value of the collateral securing the loans, and the stability of ACNB’s deposit funding sources. A significant decline in general economic conditions caused by inflation, recession, acts of terrorism, outbreak of hostilities or other international or domestic occurrences and instability, unemployment, changes in securities markets, epidemics and pandemics (such as COVID-19) and governmental responses thereto, or other factors could impact these local economic conditions and, in turn, have a material adverse effect on ACNB’s financial condition and results of operations.
19
THE EARNINGS OF FINANCIAL SERVICES COMPANIES ARE SIGNIFICANTLY AFFECTED BY GENERAL BUSINESS AND ECONOMIC CONDITIONS.
ACNB’s operations and profitability are impacted by general business and economic conditions in the United States and abroad. These conditions include short-term and long-term interest rates, inflation, money supply, political issues, legislative and regulatory changes, fluctuations in both debt and equity capital markets, broad trends in industry and finance, and the strength of the U.S. economy and the local economies in which ACNB operates, all of which are beyond ACNB’s control. Deterioration in economic conditions could result in an increase in loan delinquencies and non-performing assets, decreases in loan collateral values, and a decrease in demand for ACNB’s products and services, among other things, any of which could have a material adverse impact on ACNB’s financial condition and results of operations.
The regulatory environment for the financial services industry is being significantly impacted by financial regulatory reform initiatives in the United States and elsewhere, and regulations promulgated to implement them, including Dodd-Frank.
THE TRADING VOLUME IN ACNB’S COMMON STOCK IS LESS THAN THAT OF OTHER LARGER FINANCIAL SERVICES COMPANIES.
ACNB’s common stock trades on NASDAQ, and the trading volume in its common stock is less than that of other larger financial services companies. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the marketplace of willing buyers and sellers of ACNB’s common stock at any given time. This presence depends on the individual decisions of investors and general economic and market conditions over which ACNB has no control. Given the lower trading volume of ACNB’s common stock, significant sales of ACNB’s common stock, and the expectation of these sales, could cause ACNB’s stock price to fall.
ACNB OPERATES IN A HIGHLY REGULATED ENVIRONMENT AND MAY BE ADVERSELY AFFECTED BY CHANGES IN FEDERAL, STATE AND LOCAL LAWS AND REGULATIONS.
ACNB, primarily through its banking subsidiary, is subject to extensive regulation, supervision and/or examination by federal and state banking authorities. Any change in applicable regulations or federal, state or local legislation could have a substantial impact on ACNB and its operations. Additional legislation and regulations that could significantly affect ACNB’s powers, authority and operations may be enacted or adopted in the future, which could have a material adverse effect on its financial condition and results of operations. Further, regulators have significant discretion and authority to prevent or remedy unsafe or unsound practices or violations of laws by banks and bank and financial holding companies in the performance of their supervisory and enforcement duties. The exercise of regulatory authority may have a negative impact on ACNB’s financial condition and results of operations.
Like other financial holding companies and financial institutions, ACNB must comply with significant anti-money laundering and anti-terrorism laws. Under these laws, ACNB is required, among other things, to enforce a customer identification program and file currency transaction and suspicious activity reports with the federal government. Government agencies have substantial discretion to impose significant monetary penalties on institutions which fail to comply with these laws or make required reports. While ACNB has policies and procedures designed to prevent any such violations, there can be no assurance that such violations will not occur.
THE SOUNDNESS OF OTHER FINANCIAL INSTITUTIONS MAY ADVERSELY AFFECT ACNB.
Financial services institutions are interrelated as a result of trading, clearing, counterparty, or other relationships. ACNB has exposure to many different industries and counterparties, and routinely executes transactions with counterparties in the financial services industry, including commercial banks, brokers and dealers, investment banks, and institutional clients. Many of these transactions expose ACNB to credit risk in the event of a default by a counterparty or customer. In addition, ACNB’s credit risk may be exacerbated when the collateral held by ACNB cannot be realized upon or is liquidated at prices not sufficient to recover the full amount of the credit exposure due to ACNB. Any such losses could have a material adverse effect on ACNB’s financial condition and results of operations.
MARKET VOLATILITY AND OTHER CONDITIONS AND FACTORS MAY HAVE MATERIALLY ADVERSE EFFECTS ON ACNB’S LIQUIDITY AND FINANCIAL CONDITION.
The capital and credit markets may experience extreme volatility and disruption. In the past, in some cases, the markets have exerted downward pressure on stock prices, security prices, and credit capacity for certain issuers without regard to those issuers’ underlying financial strength. In addition, other conditions and factors that could materially adversely affect ACNB’s liquidity and funding including a lack of market or customer confidence in, or negative news about, ACNB or the financial services industry generally which also may result in a loss of deposits and/or negatively affect ACNB’s ability to access the capital markets; the loss of customer deposits to alternative investments; counterparty availability; interest rate fluctuations;
20
general economic conditions; and the legal, regulatory, accounting and tax environments governing ACNB’s funding transactions. Many of the above conditions and factors may be caused by events over which ACNB has little or no control. There can be no assurance that significant disruption and volatility in the financial markets will not occur in the future. Further, ACNB’s customers may be adversely impacted by such conditions, which could have a negative impact on ACNB’s business, financial condition and results of operations.
ACNB MAY NEED OR BE COMPELLED TO RAISE ADDITIONAL CAPITAL IN THE FUTURE WHICH COULD DILUTE STOCKHOLDERS OR BE UNAVAILABLE WHEN NEEDED OR AT UNFAVORABLE TERMS.
ACNB’s regulators or market conditions may require it to increase its capital levels. If ACNB raises capital through the issuance of additional shares of its common stock or other securities, it would likely dilute the ownership interests of current investors and would likely dilute the per share book value and earnings per share of its common stock. Furthermore, it may have an adverse impact on ACNB’s stock price. New investors may also have rights, preferences and privileges senior to ACNB’s current stockholders, which may adversely impact its current stockholders. ACNB’s ability to raise additional capital will depend on conditions in the capital markets at that time, which are outside its control, and on its financial performance. Accordingly, ACNB cannot be assured of its ability to raise additional capital on terms and/or in time frames acceptable to it, or to raise additional capital at all. If ACNB cannot raise additional capital in sufficient amounts when needed, its ability to comply with regulatory capital requirements could be materially impaired. Additionally, the inability to raise capital in sufficient amounts may adversely affect ACNB’s operations, financial condition, and results of operations.
PENNSYLVANIA BUSINESS CORPORATION LAW AND VARIOUS ANTI-TAKEOVER PROVISIONS UNDER ACNB’S ARTICLES AND BYLAWS COULD IMPEDE THE TAKEOVER OF ACNB.
Various Pennsylvania laws affecting business corporations may have the effect of discouraging offers to acquire ACNB, even if the acquisition would be advantageous to stockholders. In addition, ACNB has various anti-takeover measures in place under its articles of incorporation and bylaws, including a supermajority vote requirement for mergers, a staggered Board of Directors, and the absence of cumulative voting. Any one or more of these measures may impede the takeover of ACNB without the approval of the Board of Directors and may prevent stockholders from taking part in a transaction in which they could realize a premium over the current market price of ACNB common stock.
THE SEVERITY AND DURATION OF A FUTURE ECONOMIC DOWNTURN AND THE COMPOSITION OF THE BANKING SUBSIDIARY’S LOAN PORTFOLIO COULD IMPACT THE LEVEL OF LOAN CHARGE-OFFS AND THE PROVISION FOR CREDIT LOSSES AND MAY AFFECT ACNB’S NET INCOME OR LOSS.
Lending money is a substantial part of ACNB’s business through its banking subsidiary. However, every loan that ACNB makes carries a certain risk of non-payment. ACNB cannot assure that its allowance for credit losses will be sufficient to absorb actual loan losses. ACNB also cannot assure that it will not experience significant losses in its loan portfolio that may require significant increases to the allowance for credit losses in the future.
Although ACNB evaluates every loan that it makes against its underwriting criteria, ACNB may experience losses by reasons of factors beyond its control. Some of these factors include changes in market conditions affecting the value of real estate and unexpected problems affecting the creditworthiness of ACNB’s borrowers.
ACNB determines the adequacy of its ACL by considering various factors, including:
•An analysis of the risk characteristics of various classifications of loans;
•Previous loan loss experience;
•Specific loans that would have loan loss potential;
•Delinquency trends;
•Estimated fair value of the underlying collateral;
•Current economic conditions;
•The views of ACNB’s regulators;
•Reports of internal auditors;
•Reports of external auditors;
•Reports of loan reviews conducted by independent organizations; and,
21
•Geographic and industry loan concentrations
Local economic conditions could impact the loan portfolio of ACNB. For example, an increase in unemployment, a decrease in real estate values, or increases in interest rates, as well as other factors, could weaken the economies of the communities ACNB serves. Weakness in the Market Areas served by ACNB could depress the Corporation’s earnings and, consequently, its financial condition because:
•Borrowers may not be able to repay their loans;
•The value of the collateral securing ACNB’s loans to borrowers may decline; and/or,
•The quality of ACNB’s loan portfolio may decline
Although, based on the aforementioned procedures implemented by ACNB, management believes the current ACL is adequate, ACNB may have to increase its provision for credit losses should local economic conditions deteriorate which could negatively impact its financial condition and results of operations.
CHANGES IN REAL ESTATE VALUES MAY ADVERSELY IMPACT ACNB’S BANKING SUBSIDIARY LOANS THAT ARE SECURED BY REAL ESTATE.
A significant portion of ACNB’s banking subsidiary loan portfolio consists of residential and commercial mortgages, as well as consumer loans, secured by real estate. These properties are concentrated in ACNB’s Market Area. Real estate values and real estate markets generally are affected by, among other things, changes in national, regional or local economic conditions, fluctuations in interest rates, the availability of loans to potential purchasers, changes in the tax laws and other government statutes, regulations and policies, and acts of nature. If real estate prices decline, particularly in ACNB’s Market Area, the value of the real estate collateral securing ACNB’s loans could be reduced. This reduction in the value of the collateral could increase the number of non-performing loans and could have a material adverse impact on ACNB’s financial condition and results of operations.
ACNB CONTINUALLY ENCOUNTERS TECHNOLOGICAL CHANGE.
The financial services industry is continually undergoing rapid technological change with frequent introductions of new technology-driven products and services. The effective use of technology increases efficiency and enables financial institutions to better serve customers and to reduce costs. ACNB’s future success depends, in part, upon its ability to address the needs of its customers by using technology to provide products and services that will satisfy customer demands, as well as to create additional efficiencies in ACNB’s operations. Many of ACNB’s competitors have substantially greater resources to invest in technological improvements. ACNB may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to its customers. Failure to successfully keep pace with technological change affecting the financial services industry could have a material adverse impact on ACNB’s business and, in turn, ACNB’s financial condition and results of operations.
FINANCIAL SERVICES COMPANIES DEPEND ON THE ACCURACY AND COMPLETENESS OF INFORMATION ABOUT CUSTOMERS AND COUNTERPARTIES.
In deciding whether to extend credit or enter into other transactions, ACNB may rely on information furnished by or on behalf of customers and counterparties, including financial statements, credit reports, and other financial information. ACNB may also rely on representations of those customers, counterparties or other third parties, such as independent auditors, as to the accuracy and completeness of that information. Reliance on inaccurate or misleading financial statements, credit reports, or other financial information could have a material adverse impact on ACNB’s business and, in turn, ACNB’s financial condition and results of operations.
CONSUMERS MAY DECIDE NOT TO USE BANKS TO COMPLETE THEIR FINANCIAL TRANSACTIONS.
Technology and other changes are allowing parties to complete financial transactions that historically have involved banks through alternative methods. For example, consumers can now maintain funds in brokerage accounts or mutual funds that would have historically been held as bank deposits. Consumers can also complete transactions such as paying bills and/or transferring funds directly without the assistance of banks. The process of eliminating banks as intermediaries, known as “disintermediation”, could result in the loss of fee income, as well as the loss of customer deposits and the related income generated from those deposits. The loss of these revenue streams and the lower cost deposits as a source of funds could have a material adverse effect on ACNB’s financial condition and results of operations.
FUTURE ECONOMIC CONDITIONS MAY ADVERSELY AFFECT SECONDARY SOURCES OF LIQUIDITY.
In addition to primary sources of liquidity in the form of deposits and principal and interest payments on outstanding loans and
22
investments, ACNB maintains secondary sources that provide it with additional liquidity. These secondary sources include secured and unsecured borrowings from sources such as the Federal Reserve Bank, Federal Home Loan Bank of Pittsburgh, and third-party commercial banks. However, market liquidity conditions have been negatively impacted by past disruptions in the capital markets and could, in the future, have a negative impact on ACNB’s secondary sources of liquidity.
SEVERE WEATHER, NATURAL DISASTERS, ACTS OF WAR OR TERRORISM, GEOPOLITICAL RISKS/EVENTS, AND OTHER EXTERNAL EVENTS COULD SIGNIFICANTLY IMPACT ACNB’S BUSINESS.
The unpredictable nature of events such as severe weather, natural disasters, acts of war or terrorism (international or domestic), geopolitical risks/events, and other adverse external events could have a significant impact on ACNB’s ability to conduct business. If any of its financial, accounting, network or other information processing systems fail or have other significant shortcomings due to external events, ACNB could be materially adversely affected. Third parties with which ACNB does business could also be sources of operational risk to ACNB, including the risk that the third parties’ own network and information processing systems could fail. Any of these occurrences could materially diminish ACNB’s ability to operate one or more of the Corporation’s businesses, or result in potential liability to customers, reputational damage, and regulatory intervention, any of which could materially adversely affect ACNB. Such events could affect the stability of ACNB’s deposit base, impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans, impair ACNB’s liquidity, cause significant property damage, result in loss of revenue, and/or cause ACNB to incur additional expenses.
ACNB may be subject to disruptions or failures of the financial, accounting, network and/or other information processing systems arising from events that are wholly or partially beyond ACNB’s control, which may include, for example, computer viruses, electrical or telecommunications outages, natural disasters, disease pandemics, damage to property or physical assets, or terrorist acts. ACNB has developed a comprehensive business continuity plan which includes plans to maintain or resume operations in the event of an emergency, such as a power outage or disease pandemic, and contingency plans in the event that operations or systems cannot be resumed or restored. The business continuity plan is updated as needed, periodically reviewed, and components are regularly tested. ACNB also reviews and evaluates the business continuity plans of critical third-party service providers. While ACNB believes its business continuity plan and efforts to evaluate the business continuity plans of critical third-party service providers help mitigate risks, disruptions or failures affecting any of these systems may cause interruptions in service to customers, damage to ACNB’s reputation, and loss or liability to the Corporation.
CHANGES IN CONTROL OF THE UNITED STATES GOVERNMENT AND ISSUES RELATING TO DEBT AND THE DEFICIT MAY ADVERSELY AFFECT THE CORPORATION.
Changes in elected officials in the federal government could result in significant changes or uncertainty in governmental policies, regulatory environments, spending sentiment, and many other factors and conditions, some of which could adversely impact the Corporation’s business, financial condition, and results of operations. In addition, should the federal government encounter difficulties in reaching agreement over federal debt and issues connected with the debt ceiling, certain rating agencies may place the United States government’s long-term sovereign debt rating on their equivalent of negative watch and possibly assign a rating downgrade. As a result, the rating agencies, due to constraints related to the rating of the United States, may also place government-sponsored enterprises in which the Corporation invests and receives lines of credit on negative watch, and a downgrade of the Unites States government’s credit rating would trigger a similar downgrade in the credit rating of these government-sponsored enterprises. Furthermore, the credit rating of other entities, such as state and local governments, may also be downgraded should the United States government’s credit rating be downgraded. The impact that a credit rating downgrade may have on the national and local economy could have an adverse effect on ACNB’s financial condition and results of operations.
NEGATIVE DEVELOPMENTS AFFECTING THE BANKING INDUSTRY, INCLUDING BANK FAILURES OR CONCERNS REGARDING LIQUIDITY, MAY ERODE CUSTOMER CONFIDENCE IN THE BANKING SYSTEM AND MAY HAVE A MATERIAL ADVERSE EFFECT ON ACNB.
In the past, events impacting the banking industry, including the high-profile failures or instability of certain banking institutions, resulted in general uncertainty and eroded confidence in the safety, soundness, and financial strength of the financial services sector. In particular, the bank failures highlighted the potential serious impact of a financial institution unable to meet withdrawal requests by depositors. This resulted in a growing concern about liquidity in the banking industry, access to and volatile capital markets and reduced stock valuations for certain financial institutions. Similar future events, including additional bank failures or bank instability, could directly or indirectly adversely impact ACNB’s own liquidity, access to capital markets, stock price, financial condition and results of operations. Further, such events may also result in: greater regulatory scrutiny and enforcement; additional and more stringent laws and regulations for the financial services industry; increased FDIC deposit insurance premiums or special FDIC assessments; and higher capital ratio requirements, which as a result could have a material negative impact and adverse effect on ACNB’s business, financial condition and results of operations.
23
ACNB’S BANKING SUBSIDIARY MAY BE REQUIRED TO PAY HIGHER FDIC INSURANCE PREMIUMS OR SPECIAL ASSESSMENTS WHICH MAY ADVERSELY AFFECT ITS EARNINGS.
In the past, poor economic conditions and the resulting bank failures have increased and, in the future, may increase the costs of the FDIC and adversely impacted its Deposit Insurance Fund. Any additional bank failures may prompt the FDIC to increase its premiums or to issue special assessments. ACNB is generally unable to control the amount of premiums or special assessments that its banking subsidiary is required to pay for FDIC insurance. Any future changes in the calculation or assessment of FDIC insurance premiums may have a material adverse effect on ACNB’s financial condition and results of operations.
THE INCREASING USE OF SOCIAL MEDIA PLATFORMS PRESENTS RISKS AND CHALLENGES AND THE INABILITY OR FAILURE TO RECOGNIZE, RESPOND TO, AND EFFECTIVELY MANAGE THE ACCELERATED IMPACT OF SOCIAL MEDIA COULD MATERIALLY ADVERSELY IMPACT ACNB’S BUSINESS.
The use of social media platforms, including weblogs (blogs), social media websites, and other forms of internet-based communications allows individuals access to a broad audience of consumers and other interested persons. Social media practices in the banking industry are continually evolving, which creates uncertainty and risk of noncompliance with regulations applicable to ACNB’s business. Consumers value readily-available information concerning businesses and their goods and services, and often act on such information without further investigation and without regard to its accuracy. Many social media platforms immediately publish the content their subscribers and participants post, often without filters or checks on accuracy of the content posted. Information posted on such platforms at any time may be adverse to ACNB’s interests and/or may be inaccurate. The dissemination of information online could harm ACNB’s business, prospects, financial condition, and results of operations, regardless of the information’s accuracy. The harm may be immediate without affording ACNB an opportunity for redress or correction.
Other risks associated with the use of social media include improper disclosure of proprietary information, negative comments about ACNB’s business, exposure of personally identifiable information, fraud, out-of-date information, and improper use by employees and customers. The inappropriate use of social media by ACNB’s employees or customers could result in negative consequences such as remediation costs including training for employees, additional regulatory scrutiny, and possible regulatory penalties, litigation, or negative publicity that could damage ACNB’s reputation adversely affecting customer or investor confidence.
LITIGATION AND REGULATORY ACTIONS, INCLUDING POSSIBLE ENFORCEMENT ACTIONS, COULD SUBJECT ACNB AND ITS SUBSIDIARIES TO SIGNIFICANT FINES, PENALTIES, JUDGMENTS, OR OTHER REQUIREMENTS RESULTING IN INCREASED EXPENSES OR RESTRICTIONS ON BUSINESS ACTIVITIES.
In the normal course of business, from time to time, ACNB or its subsidiaries may be named as a defendant in various legal actions, arising in connection with their current and/or prior business activities. Legal actions could include claims for substantial compensatory or punitive damages or claims for indeterminate amounts of damages. Further, ACNB or its subsidiary bank may in the future be subject to consent orders or other formal or informal enforcement agreements with their regulators. They may also, from time to time, be the subject of subpoenas, requests for information, reviews, investigations and proceedings (both formal and informal) by governmental agencies regarding current and/or prior business activities. Any such legal or regulatory actions may subject ACNB or its subsidiaries to substantial compensatory or punitive damages, significant fines, penalties, obligations to change business practices, or other requirements resulting in increased expenses, diminished income, and damage to their reputation. Involvement in any such matters, whether tangential or otherwise, and even if the matters are ultimately determined in their favor, could also cause significant harm to their reputation and divert management attention from the operation of their business. Further, any settlement, consent order, other enforcement agreement or adverse judgment in connection with any formal or informal proceeding or investigation by governmental agencies may result in litigation, investigations or proceedings as other litigants and governmental agencies begin independent reviews of the same activities. As a result, the outcome of legal and regulatory actions could have a material adverse effect on ACNB’s business, financial condition, and results of operations.
CHANGES TO TRADE POLICIES AND TARIFFS CAN HAVE AN ADVERSE IMPACT ON OUR BUSINESS AND OUR CUSTOMERS.
Changes in trade policies, including the imposition of tariffs or the escalation of a trade war, could negatively impact the economic conditions in the markets we serve. Our customers-particularly local businesses engaged in agriculture, manufacturing, and retail-may face higher costs for imported goods and materials, reduced export demand, and supply chain disruptions due to increased tariffs. These challenges could lead to lower revenues, reduced profitability, and potential layoffs, all of which may impair our customers’ ability to meet their financial obligations. Furthermore, prolonged trade tensions and economic uncertainty could lead to market volatility, declining asset values, and weakened consumer confidence. If our
24
customers experience financial stress, we could see an increase in loan delinquencies and credit losses, negatively affecting our asset quality and overall financial performance. Additionally, any decline in local economic activity could reduce loan demand, deposit growth, and fee income, which are critical to our long-term success. While we actively monitor economic and policy developments, we cannot predict the outcome of trade negotiations or the full impact of tariffs and trade restrictions on our business, customers, and the broader economy. Any adverse effects from tariffs or a trade war could materially and negatively impact our financial condition, results of operations, and future growth prospects.
THE STOCK MARKET CAN BE VOLATILE, AND FLUCTUATIONS IN ACNB’S OPERATING RESULTS AND OTHER FACTORS COULD CAUSE ACNB’S STOCK PRICE TO DECLINE.
The stock market has experienced, and may continue to experience, fluctuations that significantly impact the market prices of securities issued by many companies and financial institutions specifically. Market fluctuations could adversely affect ACNB’s stock price. These fluctuations have often been unrelated or disproportionate to the operating performance of particular companies. These broad market fluctuations, as well as general economic, systemic, political and market conditions, such as recessions, loss of investor confidence, interest rate changes, government shutdowns, trade wars, pandemics or epidemics, or international currency fluctuations, may negatively affect the market price of ACNB’s common stock. Moreover, ACNB’s operating results may fluctuate and vary from period to period due to the risk factors set forth herein. As a result, period-to-period comparisons should not be relied upon as an indication of future performance. ACNB’s stock price could fluctuate significantly in response to ACNB’s quarterly or annual results, annual projections and the impact of these risk factors on ACNB’s operating results or financial position.
Although ACNB’s common stock is quoted on the Nasdaq Capital Market, the volume of trades on any given day has been limited historically, as a result of which stockholders might not have been able to sell or purchase ACNB’s common stock at the volume, price, or time desired. From time to time, ACNB’s common stock may be included in certain and various stock market indices. Inclusion in these indices may positively impact the price, trading volume, and liquidity of ACNB’s common stock, in part, because index funds or other institutional investors often purchase securities that are in these indices. Conversely, if ACNB’s market capitalization falls below the minimum necessary to be included in any of the indices at any annual reconstitution date, the opposite could occur. Further, ACNB’s inclusion in indices may be weighted based on the size of ACNB’s market capitalization, so even if ACNB’s market capitalization remains above the amount required to be included on these indices, if ACNB’s market capitalization is below the amount it was on the most recent reconstitution date, ACNB’s common stock could be weighted at a lower level. If ACNB’s common stock is weighted at a lower level, holders attempting to track the composition of these indices will be required to sell ACNB’s common stock to match the reweighting of the indices.
WEALTH MANAGEMENT AND INSURANCE INDUSTRY RISKS
REVENUES AND PROFITABILITY FROM ACNB’S WEALTH MANAGEMENT BUSINESS MAY BE ADVERSELY AFFECTED BY ANY REDUCTION IN ASSETS UNDER MANAGEMENT AND SUPERVISION AS A RESULT OF EITHER A DECLINE IN MARKET VALUE OF SUCH ASSETS OR NET OUTFLOWS, WHICH COULD REDUCE TRUST, INVESTMENT ADVISORY AND BROKERAGE, AND OTHER SERVICING FEES EARNED.
The wealth management business derives the majority of its revenue from noninterest income which consists of trust, investment advisory and brokerage, and other servicing fees. Substantial revenues are generated from investment management contracts with clients. Under these contracts, the investment advisory fees paid to us are typically based on the market value of assets under management. Assets under management and supervision may decline for various reasons including declines in the market value of the assets in the funds and accounts managed or supervised, which could be caused by price declines in the securities markets generally or by price declines in specific market segments. Assets under management may also decrease due to redemptions and other withdrawals by clients or termination of contracts. This could be in response to adverse market conditions or in pursuit of other investment opportunities. Any reduction in assets under management and supervision may adversely impact ACNB’s profitability.
THE WEALTH MANAGEMENT INDUSTRY IS SUBJECT TO EXTENSIVE REGULATION, SUPERVISION AND EXAMINATION BY REGULATORS, AND ANY ENFORCEMENT ACTION OR ADVERSE CHANGES IN THE LAWS OR REGULATIONS GOVERNING ACNB’S WEALTH MANAGEMENT BUSINESS COULD DECREASE ACNB’S REVENUES AND PROFITABILITY.
The wealth management business is subject to regulation by a number of regulatory agencies that are charged with safeguarding the integrity of the securities and other financial markets and with protecting the interests of customers participating in those markets. In the event of noncompliance with an applicable regulation, governmental regulators, including the SEC and FINRA, may institute administrative or judicial proceedings that may result in censure, fines, civil penalties, issuance of cease-and-desist orders, deregistration or suspension of the noncompliant broker-dealer or investment advisor, or other adverse
25
consequences. The imposition of any such penalties or orders could have a material adverse effect on the wealth management segment’s operating results and financial condition. ACNB may also be adversely affected as a result of new or revised legislation or regulations. Regulatory changes have imposed and may continue to impose additional costs, which may adversely impact ACNB’s profitability.
REVENUES AND PROFITABILITY FROM ACNB’S INSURANCE BUSINESS MAY BE ADVERSELY AFFECTED BY MARKET CONDITIONS AND COMPETITION, WHICH COULD REDUCE INSURANCE COMMISSIONS AND FEES EARNED.
The revenues of ACNB’s fee-based insurance business are derived primarily from commissions from the sale of insurance policies, which commissions are generally calculated as a percentage of the policy premium. These insurance policy commissions can fluctuate as insurance carriers from time to time increase or decrease the premiums on the insurance products sold. Due to the cyclical nature of the insurance market and the impact of other market and macroeconomic conditions on insurance premiums, commission levels may vary. The reduction of these commission rates, along with general volatility and/or declines in premiums, may adversely impact ACNB’s profitability. The fee-based insurance business is extremely competitive. ACNB competes in the fee-based insurance business with regional and national companies many of which have greater resources than ACNB. This competition may adversely impact ACNB’s fee-based insurance business.
ITEM 1B — UNRESOLVED STAFF COMMENTS
None.
ITEM 1C — CYBERSECURITY
ACNB recognizes the critical importance of identifying, assessing and managing material risks from cybersecurity threats and is committed to implementing and maintaining a comprehensive information security program to manage such risks and safeguard its systems and data. Governance of cybersecurity risk is based on the Corporation’s Information Security Program and related policies and procedures, which are designed in conformance with industry standards and compliance with Section 39 of the Federal Deposit Insurance act and sections 501 and 505(b) of GLBA, and to protect the confidentiality, integrity and availability of its information assets. The Corporation’s Board of Directors is responsible for overseeing the development, implementation and maintenance of the Corporation’s overall information security standards. The Audit Committee of the Board of Directors has enterprise risk management oversight responsibilities, which includes information security. Information Security-related functions are performed by both ACNB Bank Risk Management and Technology Services personnel. The Information Security Committee is an ACNB Bank management committee which is responsible for providing oversight and direction for information security matters and standards and meets regularly throughout the year with minutes of their meetings provided to the Corporation’s Board of Directors. ACNB Bank’s Information Security Officer is responsible for managing and monitoring the Information Security Program, and is a part of the Risk Management department, which ultimately reports to the Chief Risk Officer. Additionally, the Information Security Program is supported by ACNB Bank’s Technology Services Department which is led by the Technology Services Manager who reports to the Chief Strategy Officer.
The Information Security Program includes Information Security strategy, an incident response plan for incident management; access rights management; threat and vulnerability management; security training; risk and maturity assessments; security systems controls and standards; data use, reproduction, storage and destruction standards, intrusion prevention management, patch management, physical and environmental protections, encryption standards, malicious code prevention, intelligence sharing, and Information Security Monitoring, including architecture considerations, activity monitoring and condition monitoring. On an annual basis, Information Security-related risk assessments and a maturity analysis are performed and reported to the Board of Directors or the Board Audit Committee. Risks from cybersecurity threats associated with use of third-party service providers are addressed as part of the vendor management program, in initial and ongoing assessment of service providers. Information Security training is conducted for both employees and the Board of Directors annually. Training includes sharing educational communications to increase employee awareness of cybersecurity risks and conducting incident response plan exercises at least annually.
ACNB engages independent third-party assessors and auditors in connection with its information security program, including to conduct external and internal penetration testing and internal vulnerability scanning, independent audits and risk assessments. Technology Services personnel perform internal security practices, including regular internal vulnerability scanning using commercial software tools and follow-up with corrective measures as required, monitoring for unauthorized access attempts, uses dynamically updated Endpoint Detection and Response for anti-malware, and deploying dynamically updated firewalls to protect against unknown actors. Platforms are in place with the ability to automate containment without the risk of employee response delays and a third-party provider performs additional external vulnerability scanning, network threat detection and automated containment, risk analysis and continuous monitoring. Information Security performs monthly phishing exercises with the reporting of results to the Information Security Committee, the Senior Management Committee and an annual
26
summary of results to the Audit Committee. ACNB Bank also utilizes third-party service providers in the ordinary course of business. As part of ACNB Bank’s management program, initial and ongoing information security due diligence is reviewed and assessed on ACNB Bank’s service providers as appropriate, based on level of access to, storage of and processing of corporate and customer confidential information.

EXECUTIVE OVERVIEW
ACNB Corporation is the financial holding company for the wholly-owned subsidiaries of ACNB Bank and ACNB Insurance Services. ACNB Bank provides a full range of retail and commercial financial services in Pennsylvania and Maryland primarily through its network of 33 community banking offices. ACNB Insurance Services offers a broad range of property, casualty, health, life and disability insurance serving personal and commercial clients through office locations in Westminster, Maryland, and Gettysburg, Pennsylvania and is licensed to do business in 46 states.
The primary source of the Corporation’s revenues is net interest income derived from interest earned on loans and investments, less deposit and borrowing funding costs. Revenues are influenced by general economic factors, including market interest rates, the economies of the markets served, stock market conditions, as well as competitive forces within the markets. The Corporation also generates revenue through commissions and fees earned on various services and financial products offered to its customers and through gains on sales of assets, such as loans, investments and properties. The Corporation incurs expenses to generate the revenue through provision for credit losses, noninterest expense and income taxes. The Corporation’s overall strategy is to increase loan growth in its local markets, while maintaining a reasonable funding base by offering competitive deposit products and services.
ACNB reported earnings of $37.1 million in 2025 impacted by three discrete items: $8.3 million merger-related expenses, net of tax impact, a provision for credit losses on non-PCD loans of $4.2 million, net of tax impact, both incurred as a result of the Acquisition, and a $2.8 million loss on sales of investment securities, net of tax impact, incurred as a result of the repositioning of the investment securities portfolio.
Traditions Acquisition
ACNB closed the Acquisition of Traditions effective February 1, 2025. 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. See Note 2 — “Business Combination” in the Notes to Consolidated Financial Statements under Part II, Item 8 — “Financial Statements and Supplementary Data,” for more information.
Investment Securities Portfolio Repositioning
ACNB completed a repositioning of the investment securities portfolio by selling $74.6 million in book value of available for sale investment securities for an after-tax loss of $2.8 million as announced on Form 8-K on December 5, 2025. For additional information see “Investment Securities” in the Financial Condition section of this Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Summary Financial Results for the year ended December 31, 2025
•Net Interest Income — Net interest income was $123.1 million in 2025 compared to $83.6 million for the same period of 2024, an increase of $39.5 million. The increase in net interest income and growth in average loans and deposits was driven primarily by the Acquisition.
◦Net Interest Margin — The Corporation’s FTE net interest margin increased to 4.23% in 2025 compared to 3.79% for the same period of 2024, an increase of 44 bps. The accretion impact of acquisition accounting adjustments on loans and deposits from the Acquisition was $7.7 million for the year ended December 31, 2025.

•Asset Quality — The ACL was $23.7 million at December 31, 2025 compared to $17.3 million at December 31, 2024. The increase was driven primarily by an initial ACL of $5.5 million for non-PCD loans and $1.5 million for accruing PCD loans at the Acquisition date.
◦The provision for credit losses was $5.3 million and the provision for unfunded commitments was a reversal of $532 thousand for the year ended December 31, 2025 compared to the reversal of $2.4 million provision for credit losses and the reversal of $326 thousand for unfunded commitments for the same period of 2024.

◦Non-performing loans were $10.7 million, or 0.46% of total loans at December 31, 2025 compared to $6.8 million, or 0.40% of total loans for the same period of 2024. The increase was driven primarily by the Acquisition and, to a lesser extent, three unrelated relationships in the commercial real estate and residential mortgage portfolios.

A more thorough discussion of the Corporation’s results of operations and financial condition is included in the following pages.
CRITICAL ACCOUNTING ESTIMATES
The accounting policies that the Corporation’s management deems to be most important to the presentation of its financial condition and results of operations, because they require management’s most difficult, subjective or complex judgment, often result in the need to make estimates about the effect of such matters which are inherently uncertain. The following accounting policies are deemed to be critical by management:
Allowance for Credit Losses — The ACL represents an amount which, in management’s judgment, is adequate to absorb expected credit losses on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The ACL is measured and recorded upon the initial recognition of a financial asset. The ACL is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provision for (reversal of) credit losses, which is recorded as a current period operating expense.
Determination of an appropriate ACL is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness of the ACL is reviewed quarterly by management.
Management believes it uses relevant information available to make determinations about the ACL and that it has established the existing allowance in accordance with GAAP. However, the determination of the ACL requires significant judgment, and estimates of expected credit losses in the loan portfolio can vary from the amounts actually observed. While management uses available information to recognize expected credit losses, future additions to the ACL may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes in the interest rate environment which may directly impact prepayment and curtailment rate assumption, and changes in the financial condition of borrowers. As of December 31, 2025, the Company believes that its ACL was adequate.
Business Combinations — The Company is required to record the assets acquired, including identified intangible assets such as core deposit intangibles, and the liabilities assumed at their respective fair values in an acquisition. The difference between consideration paid and the net fair value of assets acquired is recorded as goodwill. Management uses significant estimates and assumptions to determine the fair value of such items in accordance with ASC 820, including projected cash flows, repayment rates, default rates and losses assuming default, discount rates, and realizable collateral values. The ACL for PCD loans is recognized as a component of acquisition accounting. The ACL for non-PCD assets is recognized as provision for credit losses in the same reporting period as the acquisition. Fair value adjustments are amortized or accreted into the income statement over the estimated life of the acquired assets or assumed liabilities. The purchase date valuations and any subsequent adjustments determine the amount of goodwill recognized in connection with the acquisition. The use of different assumptions could produce significantly different valuation results, which could have material positive or negative effects on our results of operations.
The determination of fair values in accordance with ASC 820 is based on valuations using management’s assumptions of future growth rates, future attrition, discount rates, multiples of earnings or other relevant factors. In addition, we engaged third party specialists to assist in the development of fair values. Preliminary estimates of fair values may be adjusted for a period of time subsequent to the acquisition date if new information is obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. Adjustments recorded during this period are recognized in the current reporting period. Management uses various valuation methodologies to estimate the fair value of these assets and liabilities, and often involves a significant degree of judgment, particularly when liquid markets do not exist for the particular item being valued. Examples of such items include loans, deposits, identifiable intangible assets, and certain other assets and liabilities.

Changes in these factors, as well as downturns in economic or business conditions, could have a significant adverse impact on the carrying value of assets, including goodwill and liabilities, which could result in impairment losses affecting our financial statements. As of December 31, 2025, the Company believes that the fair value of the assets acquired, liabilities assumed, consideration paid, and any non-controlling interests of the acquired business at fair value at the acquisition date was appropriately determined in accordance with GAAP.

RESULTS OF OPERATIONS
Net income for the year ended December 31, 2025 was $37.1 million, an increase of $5.2 million, or 16.3%, compared to net income of $31.8 million for the same period of 2024. Diluted earnings per share were $3.60 and $3.73 for the years ended December 31, 2025 and 2024, respectively.
33
Net Interest Income
The primary source of ACNB’s traditional banking revenue is net interest income, which represents the difference between interest income on earning assets and interest expense on liabilities used to fund those assets. Earning assets include loans, securities, and interest-bearing deposits with banks. Interest-bearing liabilities include deposits and borrowings. Net interest income is affected by changes in interest rates, volume of interest-bearing assets and liabilities, and the composition of those assets and liabilities. The Corporation manages the risk associated with changes in interest rates through the techniques described within Item 7a — “Quantitative and Qualitative Disclosures About Market Risk”.

FTE total interest income increased $55.8 million during 2025 compared to the same period of 2024. ACNB experienced a $38.6 million increase in interest income attributable to growth of average interest earning assets and a $17.1 million increase in the yield on interest earning assets. The average yield on interest-earning assets was 5.61% for 2025, an increase of 75 bps from the same period of 2024. FTE interest income on loans increased $52.0 million compared to the same period of 2024 due to growth in average loans and an increase in the yield on loans. Average loans increased $635.8 million while the yield increased 73 bps.
Total interest expense increased $16.3 million during 2025 compared to the same period of 2024. The increase was primarily due to a $542.1 million increase in average interest-bearing deposits and higher rates on interest-bearing deposits. The average rate paid on interest-bearing deposits was 1.41%, an increase of 58 bps during 2025. The largest increases in rates were in money markets and time deposits which increased 88 and 66 bps, respectively.

Provision for Credit Losses and Unfunded Commitments
For the year ended December 31, 2025, the provision for credit losses was $5.3 million and the provision for unfunded commitments was a reversal of $532 thousand, compared to reversals of the provisions for credit losses and unfunded commitments of $2.4 million and $326 thousand, respectively, for the same period of 2024. In 2025, 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. The reversal of the provision for unfunded commitments was impacted by the incorporation of post-COVID data which resulted in lower loss rates utilized within the Bank’s ACL model. During 2024, the Corporation revised estimates driven by a realignment of the peer group used for the CECL allowance process, an update to loss driver factors from third-party data, and an update to the application of prepayment and curtailment rate studies since implementation of CECL on January 1, 2023. These estimates, which were based on more current information available as of June 30, 2024, drove input assumptions which are used in the determination of the Corporation’s allowance for credit losses and the reserve for unfunded commitments. These updated estimates were the primary drivers for the reversal of the provision for credit losses and unfunded commitments in 2024.
The determination of the provisions was a result of the analysis of the adequacy of the allowances for credit losses and unfunded commitments calculations. Each quarter, the Corporation assesses risks and reserves required compared with the balances in the allowance for credit losses and unfunded commitments. Nonaccrual loans increased $2.0 million during 2025 driven primarily by the Acquisition and, to a lesser extent, by three unrelated lending relationships in the commercial real estate and residential mortgage portfolios. For additional discussion of the provision and the associated loans, please refer to the Asset Quality section of this Management’s Discussion and Analysis.

As announced on Form 8-K on December 5, 2025, ACNB completed a repositioning of the investment securities portfolio by selling $74.6 million in book value of AFS investment securities, consisting of lower-yielding agency debt securities, for a pre-tax loss of $3.6 million. Total noninterest income, excluding net (losses) gains on sales or calls of investment securities, totaled $32.1 million in 2025 compared to $24.7 million in the same period of 2024, a $7.5 million increase. The majority of increases were driven primarily by the Acquisition and changes to customer products. The more significant fluctuations in noninterest income that were not a direct result of the Acquisition are explained below:
•Earnings on investment in bank-owned life insurance increased driven primarily by the Acquisition and the purchase of new policies.
•Gain on life insurance proceeds were the result of a death benefit received on a life insurance policy.

Noninterest expenses increased $29.8 million in 2025 compared to the same period of 2024, driven primarily by the Acquisition. The more significant fluctuations in noninterest expenses that were not a direct result of the Acquisition are explained below:
•Salaries and employee benefits, the largest component of noninterest expenses, increased driven primarily by an increased number of employees attributable to the Acquisition, merit increases and higher mortgage commissions.
•Equipment increased $2.2 million driven primarily by the Acquisition and the implementation of additional products into our core processing system.
•Other increased $3.9 million driven primarily by the Acquisition, higher internet banking services and contributions.
•Merger-related, which include legal, external audit, loan review and advisory fees, occurred due to the Acquisition.
Income Taxes
The Corporation recognized income taxes of $9.4 million during 2025 compared to $8.6 million during 2024. The provision for income taxes reflects an ETR of 20.2% for 2025 and 21.2% for 2024. The variances from the federal statutory rate of 21% are generally due to tax-free income, which includes, but not limited to, interest income on tax-free loans and investment securities and income from bank-owned life insurance policies, federal income tax credits, the impact of non-tax deductible expenses such as certain merger-related costs and state taxes. Note 15 — “Income Taxes”, to the Consolidated Financial Statements under Part II, Item 8 — “Financial Statements and Supplementary Data,” includes a reconciliation of the federal statutory tax rate to the Corporation’s ETR, which measures income tax expense as a percentage of pretax income.
FINANCIAL CONDITION
Total assets were $3.23 billion at December 31, 2025 compared to $2.39 billion at December 31, 2024. The Acquisition contributed $877.7 million to total assets.
Investment Securities
ACNB uses investment securities to manage interest rate risk, provide collateral for certain funding products, provide liquidity and generate interest and dividend income. These securities provide the appropriate characteristics with respect to credit quality, yield and maturity relative to the management of the overall Consolidated Statement of Condition.
In December of 2025, ACNB completed a repositioning of the investment securities portfolio by selling $74.6 million in book value of AFS investment securities, consisting of lower-yielding agency investment securities, for an after-tax loss of $2.8 million. The investment securities sold had an average book yield of approximately 1.13% with a weighted-average remaining life of approximately 2.0 years. Net proceeds of $71.1 million from the sale were used to purchase higher-yielding investment securities that were all classified as AFS. The investment securities purchased consisted of $25.3 million of agency multi-family investment securities, $22.9 million agency collateralized mortgage obligation securities and $22.9 million agency mortgage-backed securities. The repositioning is estimated to improve interest income on the investment securities portfolio by
38
approximately $2.6 million over the next 12 months. ACNB expects to recover the $2.8 million after-tax loss on the sale of investment securities in approximately 1.4 years.

At December 31, 2025, the investment securities balance included a net unrealized loss on AFS investment securities of $19.5 million, net of taxes, at an amortized cost of $491.1 million compared to a net unrealized loss of $38.2 million, net of taxes, at an amortized cost of $441.6 million at December 31, 2024. The changes in fair value are deemed to be related solely to changes in market interest rates and not related to credit deterioration.
At December 31, 2025, the securities balance included HTM investment securities with an amortized cost of $63.3 million and a fair value of $57.5 million as compared to an amortized cost of $64.6 million and a fair value of $56.9 million at December 31, 2024. The Corporation's ACL on its HTM investment securities was de minimis.
The Corporation does not own investments consisting of pools of Alt-A or subprime mortgages, private label mortgage-backed securities, or trust preferred investments.

The following table discloses investment securities at the scheduled maturity date and weighted average yield at amortized cost at December 31, 2025. Mortgage-backed securities are allocated based upon scheduled maturities. Expected maturities may differ from contractual maturities because debt issuers may have the right to call or prepay obligations without call or prepayment penalties. Therefore, the stated yield may not be recognized in future periods. Additionally, residential mortgage-backed securities, which are collateralized by residential mortgage loans, typically prepay at a rate faster than the stated maturity. See “Note 4 — Investment Securities” for additional details.

Total Loans, Net of Unearned Income$2,330,514 $1,682,910 $647,604 38.5 %
The increase in total loans, net of unearned income, was driven primarily by $648.5 million in loans purchased at the Acquisition date. Total acquisition accounting adjustments on loans were $18.2 million at December 31, 2025. The majority of the loan acquisition accounting adjustments are expected to accrete back through as income as loans pay off or mature. Growth in the portfolio was spread throughout ACNB’s geographic footprint and across various property types. The collateral for the loans is primarily spread across the Bank’s Market Area. Despite the intense competition in these areas, management continues to focus on asset quality and disciplined underwriting standards in the loan origination process. ACNB does not have a
40
significant concentration of credit risk with any single borrower, industry or geographic location. Most of the Corporation’s lending activities are with customers located within the Bank’s Market Area.
The commercial real estate portfolio grew $304.3 million in 2025. The collateral for these loans is primarily spread across Pennsylvania and Maryland, 65.8% and 32.1%, respectively, at December 31, 2025 compared to 56.0% and 42.1%, respectively, at December 31, 2024. Less than 3% of the portfolio is for real estate in Urban areas such as Baltimore, Maryland and Philadelphia, Pennsylvania. The largest sectors of the commercial real estate portfolio are retail and mixed-use commercial rental units, office complexes, apartment complexes and hotels, motels and bed and breakfast entities. Non-owner occupied commercial real estate represented 65.4% of the commercial real estate portfolio at December 31, 2025, compared to 62.3% at December 31, 2024. Non-owner occupied commercial real estate borrowers are geographically dispersed throughout ACNB’s Market Area and are leasing commercial properties to a varied group of tenants including medical offices, retail space, and other commercial purpose facilities. Because of the varied nature of the tenants in aggregate, management believes that these loans present an acceptable risk when compared to commercial loans in general.
The following chart details the percentage of the various segments included in the portfolio:
5385 5388
______________________________________________________________
1 Constitutes over 40 loan categories that do not fit into the categories presented above
The concentration of non-owner occupied commercial real estate, construction, and multi-family was 239.0% of total risk-based capital of the Bank as of December 31, 2025 compared to 207.0% of total risk-based capital of the Bank as of December 31, 2024. The increase was primarily a result of the Acquisition.
Residential real estate mortgages totaled $599.1 million, an increase of $197.1 million, or 49.0%, in 2025. Included in the residential real estate mortgages are $221.1 million of commercial loans primarily for investment properties and $61.3 million of consumer loans secured by residential real estate mortgages. Total residential real estate mortgages include $50.7 million in junior liens. Junior liens inherently have more credit risk by virtue of the fact that another financial institution may have a senior security position in the case of foreclosure liquidation of collateral to extinguish the debt.
Commercial and industrial loans totaled $205.5 million, an increase of $64.5 million, or 45.8% in 2025. This segment includes loans to school districts, municipalities (including townships) and essential purpose authorities. In many cases, these loans are obtained through a bid process that includes other local and regional banks and are especially subject to refinancing in certain rate environments.

The following table presents the maturity schedule of the loan portfolio, segmented based on the underlying collateral, at December 31, 2025. Loans with variable rates or floating interest rates include adjustable-rate instruments that may have a remaining period of fixed rate interest, and in some instances, multiple years of a fixed rate interest period.

Asset Quality
The ACNB loan portfolio is subject to varying degrees of credit risk. Credit risk is mitigated through prudent and disciplined underwriting standards, ongoing credit review, and monitoring and reporting asset quality measures. Additionally, loan portfolio diversification, limiting exposure to a single industry or borrower, and requiring collateral also reduces ACNB’s credit risk. ACNB’s commercial, consumer and residential mortgage loans are principally to borrowers in ACNB’s Market Area. As the majority of ACNB’s loans are located in this area, a substantial portion of the debtor’s ability to honor the obligation may be affected by the level of economic activity in the Market Area.
The accrual of interest on residential mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in the process of collection. Consumer loans (consisting of home equity lines of credit and consumer loan categories) are typically charged off no later than 120 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. ACNB occasionally returns nonaccrual loans to performing status when the borrower brings the loan current and performs in accordance with contractual terms for a reasonable period of time.
For loans to borrowers with commercial purposes, an internal risk rating process is used to monitor credit quality. For a complete description of the Corporation’s risk ratings, refer to the “Allowance for Credit Losses” section within Note 1 — “Summary of Significant Accounting Policies,” in the Notes to Consolidated Financial Statements in Item 8 — “Financial Statements and Supplementary Data”.

Foreclosed assets held for resale consist of the fair value of real estate acquired through foreclosure on real estate loan collateral or the acceptance of ownership of real estate in lieu of the foreclosure process. Fair values are based on appraisals that consider the sales prices of similar properties in the proximate vicinity less estimated selling costs. Foreclosed assets held for resale totaled $19 thousand, consisting of one property, at December 31, 2025 compared to two properties totaling $438 thousand at December 31, 2024.
Allowance for Credit Losses
In 2023, the Corporation adopted ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, universally referred to as CECL which replaced the prior incurred loss methodology. The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, including loans, HTM securities and purchased financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. It also applies to OBS credit exposures such as loan commitments, standby letters of credit, financial guarantees and other similar instruments.
ACNB maintains the ACL at a level believed to be adequate by management to absorb current expected losses in the loan portfolio, and it is funded through a provision for credit losses charged to earnings.

The increase in the ACL for the year ended December 31, 2025 compared to the prior year was driven primarily by the higher provision for credit losses during 2025 related to the Acquisition. Total internally risk rated loans were $1.80 billion as of December 31, 2025 with a related ACL of $19.0 million.

The Bank relies on deposits as a primary source of funds for lending activities. The Bank’s deposit pricing function employs a disciplined approach based upon liquidity needs and alternative funding rates, but also strives to price deposits to be competitive with relevant local competition, including local government investment trusts, credit unions and larger regional banks.
The increase in deposits from December 31, 2024 to December 31, 2025 was driven primarily by the Acquisition. ACNB acquired $741.5 million in deposits at the Acquisition date. Total demand and savings deposits increased $477.8 million and time deposits increased $179.9 million. Included in time deposits was $59.1 million in brokered time deposits issued by the Bank. Total deposits as of December 31, 2025 were comprised of approximately 61% consumer deposits and 39% commercial deposits, compared to approximately 63% consumer deposits and 37% commercial deposits as of December 31, 2024. The loan-to-deposit ratio was 95.12% at December 31, 2025 compared to 93.89% at December 31, 2024.
Included in total deposits at December 31, 2025 were municipal deposits totaling $119.3 million, or 4.9%, of total deposits compared to $111.0 million, or 6.2%, of total deposits at December 31, 2024. Uninsured and non-collateralized deposits to total Bank deposits was 17.7% compared to 16.3% at December 31, 2025 and 2024, respectively. As of December 31, 2025, cash on hand, the fair value of unencumbered investment securities and collateralized borrowing capacities at the FHLB and the Federal Reserve discount window at the Bank were 342.7% of uninsured and non-collateralized Bank deposits. At December 31, 2025 deposits from the 20 largest depositors, excluding internal accounts, of the Bank totaled $177.2 million, or 7.2%, of total Bank deposits compared to $143.4 million, or 7.9%, of total Bank deposits at December 31, 2024.

1Net of purchase accounting fair value mark.
Short-term borrowings are comprised primarily of securities sold under agreements to repurchase, short-term borrowings from the FHLB and federal funds purchased. Fluctuations in securities sold under agreements to repurchase balances are due to normal changes in the cash flow position of ACNB’s commercial and local government customer base. Agreements to
45
repurchase accounts are within the commercial and local government customer base and have attributes similar to core deposits. Investment securities are pledged in sufficient amounts to collateralize these agreements. Short-term FHLB borrowings are used for general balance sheet management.
Long-term borrowings consist of longer-term advances from the FHLB, trust preferred subordinated debt and subordinated debt. Further borrowings will be used when necessary for a variety of risk management and funding purposes. Please refer to the Liquidity discussion below for more information on the Corporation’s ability to borrow.
Capital
ACNB’s capital management strategies have been developed to provide an appropriate rate of return relative to management’s identification and management of risk, in the opinion of management, to stockholders, while maintaining levels above its internal minimums and “well capitalized” regulatory position in relationship to its risk exposure. Total stockholders’ equity was $420.0 million at December 31, 2025 compared to $303.3 million at December 31, 2024. Stockholders’ equity increased primarily due to the $83.6 million issuance of common stock to acquire Traditions, net income of $37.1 million and a $18.6 million change in unrealized gains in AFS investment securities partially offset by $14.4 million in cash dividends paid to ACNB Corporation stockholders and $11.2 million of common stock repurchases.

ACNB has a Dividend Reinvestment and Stock Purchase Plan that provides registered holders of ACNB common stock with a convenient way to purchase additional shares of common stock by permitting participants in the plan to automatically reinvest cash dividends on all or a portion of the shares owned and to make quarterly voluntary cash payments under the terms of the plan. Participation in the plan is voluntary, and there are eligibility requirements to participate in the plan. During the year ended December 31, 2025, 15,419 shares were issued under this plan. Proceeds from the plan are used for general corporate purposes.
On June 18, 2025, the Corporation announced that the Board of Directors approved a plan to repurchase, in open market transactions at prevailing market prices, up to 314,000 shares, or approximately 3%, of the outstanding shares of ACNB’s common stock. This common stock repurchase program replaced and superseded any and all earlier announced repurchase plans. There were 116,929 shares purchased under this plan during 2025.
On October 24, 2022, the Corporation announced that the Board of Directors approved on October 18, 2022 a new plan to repurchase, in open market and privately negotiated transactions, up to 255,575, or approximately 3%, of the outstanding shares of the Corporation’s common stock. There were 215,372 treasury shares purchased under this plan through June 30, 2025. The plan was replaced by the plan announced on June 18, 2025.
Regulatory Capital Requirements
The Corporation and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s Consolidated Financial Statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain OBS items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
Minimum regulatory capital requirements established by Basel III rules require the Corporation and the Bank to:
•Meet a minimum Tier 1 leverage capital ratio of 4.0% of average assets;
•Meet a minimum Common Equity Tier 1 capital ratio of 4.5% of risk-weighted assets;
•Meet a minimum Tier 1 capital ratio of 6.0% of risk-weighted assets;
•Meet a minimum Total capital ratio of 8.0% of risk-weighted assets;
•Maintain a “capital conservation buffer” of 2.5% above the minimum risk-based capital requirements, which must be maintained to avoid restrictions on capital distributions and certain discretionary bonus; and,
•Comply with the definition of capital to improve the ability of regulatory capital instruments to absorb losses.
46
ACNB considers the capital ratios of the banking subsidiary to be the relevant measurement of capital adequacy. The banking subsidiary’s capital ratios are as follows:
20252024To be Well
Capitalized under
Prompt Corrective
Action Regulations
Tier 1 leverage ratio (to average assets)10.92 %12.03 %5.00 %
Common Tier 1 capital (to risk-weighted assets)14.32 %16.03 %6.50 %
Tier 1 risk-based capital ratio (to risk-weighted assets)14.32 %16.03 %8.00 %
Total risk-based capital ratio (to risk-weighted assets)15.30 %17.02 %10.00 %
Quantitative measures established by regulation to ensure capital adequacy require ACNB to maintain minimum amounts and ratios of total and Tier 1 capital to average and risk adjusted assets. Management believes, as of December 31, 2025 and 2024, that ACNB’s banking subsidiary met all minimum capital adequacy requirements to which it is subject and is categorized as “well capitalized” for regulatory purposes. There are no subsequent conditions or events that management believes have changed the banking subsidiary’s category.
For further information on the actual and required capital amounts and ratios, please refer to Note 16 — “Regulatory Matters” in the Notes to Consolidated Financial Statements.
Liquidity
Effective liquidity management ensures the cash flow requirements of depositors and borrowers as well as the operating cash needs of ACNB are met. ACNB’s funds are available from a variety of sources, including assets that are readily convertible such as interest-bearing deposits with banks, maturities and repayments from the securities portfolio, scheduled repayments of loans receivable, the core deposit base, the ability to raise brokered deposits, and the ability to borrow from the FHLB, Federal Reserve Discount Window and unsecured Federal Funds line providers.
At December 31, 2025, ACNB’s banking subsidiary could borrow $1.29 billion from the FHLB of which $1.01 billion was available. At December 31, 2025, ACNB’s banking subsidiary could borrow $57.0 million from the Discount Window, of which the full amount was available. The underlying collateral at the Discount Window is made up of eligible loan collateral held in a joint-custody account under the Bank’s name.
ACNB’s banking subsidiary maintains several unsecured Fed Funds lines with correspondent banks. As of December 31, 2025, Fed Funds line capacity at the banking subsidiary was $192.0 million, of which the full amount was available. ACNB maintains a $5.0 million unsecured line of credit with a correspondent bank, all of which was available for borrowing at December 31, 2025. The Corporation also executed a guaranty for a note related to a $1.5 million commercial line of credit from a local bank, with customary terms and conditions for such a line, for ACNB Insurance Services, the borrower and wholly-owned subsidiary of ACNB Corporation. The commercial line of credit is for general working capital needs as they arise by ACNB Insurance Services.
Another source of liquidity is securities sold under repurchase agreements to customers of the Bank totaling $16.1 million and $15.8 million at December 31, 2025 and 2024, respectively. These agreements vary in balance according to the cash flow needs of customers and competing accounts at other financial organizations.
The liquidity of the parent company also represents an important aspect of liquidity management. The parent company’s cash outflows consist principally of dividends to stockholders, common stock repurchases and corporate expenses. The main source of funding for the parent company is the dividends it receives from its subsidiaries. Federal and state banking regulations place certain legal restrictions and other practicable safety and soundness restrictions on dividends paid to the parent company from the subsidiary bank. For a discussion of ACNB’s dividend restrictions, please refer to Item 1 — “Business” and Note 16 — “Regulatory Matters” in the Notes to Consolidated Financial Statements.
ACNB manages liquidity by monitoring projected cash inflows and outflows on a daily basis, and believes it has sufficient funding sources to maintain sufficient liquidity under varying degrees of business conditions for liquidity and capital resource requirements for all material short- and long-term cash requirements from known contractual and other obligations.
Off-Balance Sheet Arrangements
The Corporation is party to financial instruments with OBS risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and, to a lesser extent, standby letters of credit. At December 31, 2025 the Corporation had unfunded outstanding commitments to extend credit of $566.8 million and
47
outstanding standby letters of credit of $24.4 million. Because these commitments generally have fixed expiration dates and many will expire without being drawn upon, the total commitment level does not necessarily represent future cash requirements. Please refer to Note 17 — “Commitments and Contingencies” in the Notes to Consolidated Financial Statements for a discussion of the nature, business purpose, and importance of the Corporation’s OBS arrangements.
New Accounting Pronouncements
See Note 1 — “Summary of Significant Accounting Policies” in the Notes to Consolidated Financial Statements for a summary of these new accounting pronouncements not yet adopted.
ITEM 7A — QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS
The primary objective of ACNB’s ALCO with direct oversight from the Board is to maximize net interest income within established policy parameters. This objective is accomplished through the management of the statement of condition composition and duration, market risk exposures arising from changing economic conditions, and liquidity risk.
Market risk comprises exposure to interest rate risk, foreign currency exchange rate risk, commodity price risk, and other relevant market rate or price risks. Specific to the banking industry, one of the greatest risk exposures is to that of changing market interest rates. The primary objective of monitoring ACNB’s interest rate sensitivity risk is to provide management the flexibility necessary to manage the statement of condition to minimize adverse changes in net interest income as a result of changes in the direction and level of interest rates. FOMC monetary policy, economic uncertainty, and fiscal policy changes have been significant factors affecting the task of managing interest rate sensitivity positions in recent years.
ACNB’s ALCO is a management committee responsible for monitoring and managing interest rate risk within approved policy limits, utilizing earnings sensitivity simulation and economic value-at-risk models. These models are highly dependent on various assumptions, which change regularly as the statement of condition composition and market interest rates change. The key assumptions and strategies employed are analyzed, reviewed and documented at least annually by the ALCO as well as provided to the Board.
Interest Rate Risk
Interest rate risk is the exposure to fluctuations in the Bank’s future earnings (earnings at risk) and value (value at risk) resulting from changes in interest rates. This exposure results from differences between the amounts of interest-earning assets and interest-bearing liabilities that reprice within a specified time period as a result of scheduled maturities, scheduled and unscheduled repayments, the propensity of borrowers and depositors to react to changes in their economic interests, and contractual loan interest rate changes.
Management attempts to manage the level of repricing and maturity mismatch through its asset/liability management processes so that fluctuations in net interest income are maintained within policy limits across a range of market conditions while satisfying liquidity and capital requirements. Management recognizes that a certain amount of interest rate risk is inherent, appropriate, and necessary to ensure the Bank’s profitability. Thus, the goal of the Bank’s interest rate risk management is to minimize the fluctuations of net interest income across all interest rate scenarios.
Management endeavors to control the exposure to changes in interest rates by understanding, reviewing, and making decisions based on its risk position. The Bank primarily uses its securities portfolio, FHLB advances, derivatives and brokered deposits to manage its interest rate risk position. Additionally, pricing, promotion, and product development activities are directed in an effort to emphasize the loan and deposit repricing characteristics that best meet current interest rate risk objectives.
ACNB uses simulation analysis to assess earnings at risk and net present value analysis to assess value at risk. These methods allow management to regularly monitor both the direction and magnitude of its interest rate risk exposure. These analyses require numerous assumptions including, but are not limited to, changes in the statement of condition mix, prepayment rates on loans and securities, cash flows and repricing of all financial instruments, changes in volumes and pricing, future shapes of the yield curve, relationship of market interest rates to each other (basis risk), credit spread, and deposit sensitivity. Assumptions are based on management’s best estimates, but may not accurately reflect actual results under certain changes in interest rates due to the timing, magnitude, and frequency of rate changes and changes in market conditions and management strategies, among other factors. However, the analyses are useful in quantifying risk and providing a relative gauge of the Corporation’s interest rate risk position over time.
ACNB’s ALCO operates under management policies, approved by the Board, which define guidelines and limits on the level of risk. ALCO meets regularly and reviews its interest rate risk position and monitors various liquidity ratios to ensure a satisfactory liquidity position. By utilizing the analyses, management can determine changes that may need to be made to the asset and liability mixes to mitigate the change in net interest income under various interest rate scenarios. Management
48
continually evaluates the condition of the economy, the pattern of market interest rates, and other economic data to inform the committee. Regulatory authorities also monitor the Corporation’s interest rate risk position along with other liquidity ratios.
Net Interest Income Sensitivity
Simulation analysis evaluates the effect of upward and downward changes in market interest rates on future net interest income. The analysis involves changing the interest rates used in determining net interest income over the next twelve months. The resulting percentage change in net interest income in various rate scenarios is an indication of Corporation’s short-term interest rate risk. The analysis assumes recent pricing trends in new loan and deposit volumes will continue while balances remain constant. Additional assumptions are applied to modify pricing under the various rate scenarios.
The simulation analysis results are presented in the table below. At December 31, 2025, results in the falling or rising interest rate scenarios project a decrease in net interest income. The Bank is currently modestly asset-sensitive according to the model in a down rate environment as interest-earning assets are expected to reprice faster than interest-bearing liabilities.

Economic Value
Net present value analysis provides information on the risk inherent in the statement of condition that might not be considered in the simulation analysis due to the short time horizon used. The net present value of the statement of condition incorporates the discounted present value of expected asset cash flows minus the discounted present value of expected liability cash flows. The analysis involves changing the interest rates used in determining the expected cash flows and in discounting the cash flows. The resulting percentage change in net present value in various rate scenarios is an indication of the longer-term repricing risk and options embedded in the statement of condition.
The results at December 31, 2025 and 2024 are reflected in the following table. Funding cost and repricing speed will continue to be a factor in the results of the model. The behavior of the business and retail clients also varies across the rate scenarios, which is reflected in the results. To improve comparability across periods, the Bank strives to follow best practices related to the assumption setting and maintains the size and mix of the period end statement of condition; thus, the results do not reflect actions management may take through the normal course of business that would impact results.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated statements of condition of ACNB Corporation (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025, and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
51
assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing a separate opinion on the critical audit matters or on the accounts or disclosures to which they relate.

Allowance for Credit Losses on Loans

As described in Notes 1 and 5, the Company’s methodology for estimating the allowance for credit losses on loans includes quantitative and qualitative components of the calculation. The Company’s loan portfolio is segmented by loan types that behave similarly during economic cycles. The quantitative analysis includes using a discounted cash flow (DCF) model for determining the allowance for credit losses. Economic forecasts are used in the model to estimate the probability of default and loss given default through regression which are key inputs into the DCF model calculation. Quantitative model assumptions include, but are not limited to the discount rate, prepayment speeds, and curtailments. The quantitative model output is adjusted with qualitative adjustments. Management develops a qualitative framework that serves as the basis for determining the reasonableness of the model’s output and makes qualitative adjustments as necessary. The allowance methodology is inherently complex and requires the use of significant management judgment.

We determined that auditing the allowance for credit losses on loans was a critical audit matter because of the extent of auditor judgment applied and significant audit effort to evaluate the significant subjective and complex judgments made by management, including segmentation, the economic forecasts used to calculate the regressions within the DCF model, the quantitative model assumptions as mentioned above, and the qualitative adjustments made using the qualitative framework. In addition, we used individuals with specialized skill or knowledge to assist us in auditing the judgments made by management.

The primary procedures performed to address this critical audit matter included the following:

•Tested the operating effectiveness of the Company’s controls that addressed the following:
◦Management’s selection and application of the DCF model, including the evaluation of the reasonableness of the segmentation, the reasonable and supportable economic forecasts, the significant model assumptions, and the relevance and reliability of data used in the model, and the validation of the DCF model outputs.
◦Management’s review of the appropriateness of the qualitative framework, the reasonableness of significant assumptions applied, the relevance and reliability of data used in the qualitative adjustments, and the mathematical accuracy of the qualitative adjustments calculation.
•Evaluated the reasonableness of management’s judgments related to the selection of the segmentation, DCF model, the reasonable and supportable economic forecasts, the significant model assumptions, and the relevance and reliability of the data used in the DCF model.
•Tested the mathematical accuracy and application of the DCF model including engaging individuals with specialized skills in to validate the DCF model outputs.
•Evaluated the reasonableness of qualitative adjustments, including evaluating the appropriateness of the qualitative framework, the assumptions and judgments applied in the determination of the qualitative adjustments, the relevance and reliability of data used in the qualitative adjustments, and the mathematical accuracy of the qualitative adjustments calculation.

Business Combination – Fair Value of Acquired Loans

As described in Notes 1 and 2, during 2025, the Company completed the acquisition of Traditions Bancorp, Inc. for stock and cash consideration totaling approximately $83.8 million on February 1, 2025. Accounting for an
52
acquisition requires management to record the assets acquired and liabilities assumed at fair value as of the date of acquisition. The estimation of fair values related to acquired loans required management to make significant judgments and assumptions. The acquired loans were recorded at $648.5 million. The determination of fair values over acquired loans involves significant judgment by management regarding methods and assumptions, including discount rates, default rates, and repayment rates. For acquired loans at the merger date, management evaluated and classified loans based upon whether the loans had experienced a more-than-insignificant amount of credit deteriorating since origination. The factors considered in evaluating more-than-insignificant credit deterioration included, but not limited to, loans 30 days or more past due, loans with an internal risk grade below average or lower, or loans classified as non-accrual.

We identified auditing the fair value of acquired loans as a critical audit matter because it involved especially subjective auditor judgment and audit effort to evaluate the significant judgments made by management, including the need for professionals with specialized skill or knowledge.

The primary procedures performed to address this critical audit matter included the following:

•Tested the operating effectiveness of the Company’s controls that addressed the following:
◦Evaluation of the appropriateness of methods and assumptions applied in the estimate of fair value over the acquired loans.
◦Identification of acquired loans that had experienced more-than-insignificant amount of credit deterioration.
◦Evaluation of the relevance and reliability of external data used in the valuation of acquired loans.
◦Completeness and accuracy of loan data used in the valuation of acquired loans.
•Substantively test the estimate of the fair value of acquired loans, including developing independent expectations and applying those independently developed significant assumptions in the calculation with the assistance of professionals with specialized skill and knowledge.
•Evaluation of the relevance and reliability of external data used in the valuation of acquired loans.
•Evaluation of criteria used to identify the population of loans that had experienced a more-than-insignificant amount of credit deterioration since origination and completeness of population.
•Testing the completeness and accuracy of loan data used in the calculation.

ACNB CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Nature of Operations
ACNB Corporation, headquartered in Gettysburg, Pennsylvania, provides banking, wealth management, mortgage and insurance services to businesses and consumers through its wholly-owned subsidiaries, ACNB Bank and ACNB Insurance Services. The Bank engages in full-service commercial and consumer banking and wealth management services, including trust and retail brokerage, through its 33 community banking offices, including 24 community banking office locations in Adams, Cumberland, Franklin, Lancaster and York Counties, Pennsylvania, and nine community banking office locations in Carroll and Frederick Counties, Maryland. There are also loan production offices in West Lawn, Pennsylvania and Hunt Valley, Maryland.
ACNB Insurance Services is a full-service insurance agency based in Westminster, Maryland, with an additional location in Gettysburg, Pennsylvania. The agency offers a broad range of property, casualty, health, life and disability insurance to both individual and commercial clients.
Basis of Financial Statements
The Consolidated Financial Statements have been prepared in accordance with GAAP and include the accounts of the Corporation and its wholly-owned subsidiaries. All significant intercompany transactions have been eliminated.
Certain amounts in the prior years’ Consolidated Financial Statements and notes have been reclassified to conform to the current presentation. The Corporation evaluates subsequent events through the filing of this report with the SEC.
Recent Merger
Effective February 1, 2025, ACNB acquired Traditions Bancorp, Inc., 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. ACNB Bank is operating the former Traditions Bank offices as “Traditions Bank, A Division of ACNB Bank”. Traditions Bank operated eight community banking offices in South Central Pennsylvania which were included in the acquisition. In April 2025, ACNB consolidated two of the eight Traditions Bank offices into nearby ACNB Bank offices. In connection with the Acquisition, Traditions stockholders received 0.7300 shares of ACNB Corporation common stock for each share of Traditions common stock that they owned as of the effective date and time, with cash paid in lieu of fractional shares. ACNB issued 2,035,246 shares of its common stock, and cash in exchange for fractional shares based on $41.10 per whole share of ACNB common stock. The Acquisition was valued at $83.8 million. ACNB finalized the accounting for this transaction and completed the allocation of the purchase consideration to the assets acquired and liabilities assumed. As of December 31, 2024, Traditions had total assets of $870.1 million, total loans of $674.4 million and total deposits of $749.3 million. Common shares outstanding totaled 2,788,164 at December 31, 2024. See “Note 2 — Business Combination” for additional details.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses.
Cash and Cash Equivalents
Cash and cash equivalents include cash on hand, balances due from banks, and federal funds sold, all of which mature within 90 days and interest-bearing deposits with banks. Net cash flows are reported for customer loan and deposit transactions, interest-bearing deposits in other financial institutions, and federal funds purchased and repurchase agreements. Interest-bearing deposits at other financial institutions are carried at cost.
Investment Securities
On January 1, 2023 the Corporation adopted ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, universally referred to as CECL. ASU 2016-13 applies to all financial instruments carried at amortized cost, including HTM securities, and makes targeted improvements to the accounting for credit losses on AFS securities. In addition, Topic 326 amends the accounting for credit losses on certain other debt securities. The Corporation
60
Table of Contents
did not record any allowance for credit losses on its HTM debt securities and did not record any impairment on its AFS debt securities as a result of adopting Topic 326.
The Corporation continuously monitors any changes in economic conditions, credit downgrades, changes to explicit or implicit guarantees granted to certain debt issuers, and any other relevant information that would indicate potential credit deterioration on the Corporation’s investment securities. As of December 31, 2025, the ACL related to HTM debt securities was de minimis and there was no impairment recorded for AFS securities.
Equity securities with readily determinable fair values are recorded at fair value with changes in fair value recognized in net income. Debt securities that management has the positive intent and ability to hold to maturity are classified as “held to maturity” and recorded at amortized cost. Debt securities not classified as HTM or trading are classified as “available for sale” and recorded at fair value, with unrealized gains and losses excluded from earnings and reported, net of tax, in other comprehensive income.
Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. In relation to HTM securities, any declines in the fair value that are assumed to impair the credit quality of such debt instruments are evaluated and the estimated loss is incorporated into the Banks’ expected credit losses for any given period. In estimating impairment losses on debt securities, management considers (1) whether management intends to sell the security, or (2) if it is more likely than not that management will be required to sell the security before recovery, or (3) if management does not expect to recover the entire amortized cost basis. In assessing potential impairment for equity securities, consideration is given to management’s intention and ability to hold the securities until recovery of unrealized losses. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.
Transfers of debt securities from the AFS classification to the HTM classification are made at fair value at the date of transfer. The unrealized holding gain or loss at the date of transfer is recognized in other comprehensive income (loss) and in the carrying value of the HTM securities. Such amounts are amortized into income over the remaining expected life of the security.
Loans Held for Sale
The Corporation previously elected to measure loans originated and intended for sale in the secondary market at the lower of aggregate cost or fair value. Net unrealized losses were recognized through a valuation allowance by charges to income. During the first quarter of 2025, management made the decision to measure loans held for sale at fair value to more appropriately reflect the performance of its entire mortgage banking activities in its Consolidated Financial Statements. The impact of the change in accounting policy for prior periods presented was deemed to be immaterial. Derivative financial instruments related to mortgage banking activities are also recorded at fair value, as detailed under the header “Derivative Financial Instruments and Hedging Activities” below and in Note 12 — “Derivative Financial Instruments.” Changes in the fair value of loans held for sale and derivative financial instruments related to mortgage banking during the period are recorded as components of gain from mortgage loans held for sale on the Consolidated Statements of Income. Interest income earned on mortgage loans held for sale is classified within interest income on the Consolidated Statements of Income.
Mortgage loans held for sale are sold with the mortgage servicing rights released to another financial institution through a correspondent relationship. The correspondent financial institution absorbs all of the risk related to rate lock commitments. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold.
Loans
The Corporation grants commercial, residential, and consumer loans to customers. A substantial portion of the loan portfolio is represented by commercial real estate and residential mortgage loans throughout South-central Pennsylvania and Northern Maryland. The ability of the Corporation’s debtors to honor their contracts is dependent upon the real estate values and general economic conditions in this area.
Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield using the effective interest method.
The loans receivable portfolio is segmented into commercial, residential mortgage, home equity lines of credit, and consumer loans. Commercial loans consist of the following classes: commercial real estate, commercial and industrial and real estate construction.
The accrual of interest on commercial loans and residential mortgage is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Consumer loans, including home equity lines of credit, are
61
Table of Contents
typically charged off no later than 120 days past due. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. Facts and circumstances can arise that cause a loan to be placed on nonaccrual if payment capacity is insufficient.
All interest accrued, but not collected, for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method until qualifying for return to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Credit Losses
In 2023 the Corporation adopted ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, universally referred to as CECL which replaced the prior incurred loss methodology. The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, including loans, HTM securities and purchased financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. It also applies to OBS credit exposures such as loan commitments, standby letters of credit, financial guarantees and other similar instruments.
The Corporation maintains an ACL at a level determined to be adequate to absorb expected credit losses associated with the Corporation’s financial instruments over the life of those instruments as of the balance sheet date. The Corporation’s systematic ACL methodology is based on the following portfolio segments: Commercial Real Estate, Residential Mortgage, Commercial and Industrial, Home Equity Lines of Credit, Real Estate Construction and Consumer. The loan portfolio is segmented by loan types that have similar risk characteristics and types of collateral and that behave similarly during economic cycles. The calculation includes both a quantitative and qualitative component which incorporates the forecasting of certain economic variables. The Bank engages a third-party to assist with validation of the CECL model, including the data, assumptions, calculations and methodologies used. The Bank’s CECL Committee, which includes members from Credit Administration, Accounting/Finance, Risk Management and Internal Audit, has oversight by the Chief Executive Officer, Chief Financial Officer, and Chief Credit Officer.
The following is a discussion of the key risks by portfolio segment that management assesses in preparing the ACL.
Commercial Real Estate — The Corporation engages in commercial real estate lending in its Market Area and surrounding areas. The portfolio is secured primarily by commercial retail space, office buildings, and hotels. Generally, commercial real estate loans have terms that do not exceed 20 years, have loan-to-value ratios of up to 80% of the appraised value of the property, and are typically secured by personal guarantees of the borrowers.
In underwriting these loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history, and the reliability and predictability of the cash flow generated by the property securing the loan. Appraisals on properties securing commercial real estate loans originated by the Corporation are performed by independent appraisers.
Commercial real estate loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions and the complexities involved in valuing the underlying collateral.
Residential Mortgage — One-to-four family residential mortgage loan originations, including home equity closed-end loans, are generated by the Corporation’s marketing efforts, its present customers, walk-in customers, and referrals. These loans originate primarily within the Corporation’s Market Area or with customers primarily from the Market Area.
The Corporation offers fixed-rate and adjustable-rate mortgage loans with terms up to a maximum of 30 years for both permanent structures and those under construction. The Corporation’s one-to-four family residential mortgage originations are secured primarily by properties located in its primary Market Area and surrounding areas. The majority of the Corporation’s residential mortgage loans originate with a loan-to-value of 80% or less. Loans in excess of 80% are required to have private mortgage insurance.
In underwriting one-to-four family residential real estate loans, the Corporation evaluates both the borrower’s financial ability to repay the loan as agreed and the value of the property securing the loan. Properties securing real estate loans made by the Corporation are appraised by independent appraisers. The Corporation generally requires borrowers to obtain an attorney’s title opinion or title insurance, as well as fire and property insurance (including flood insurance, if necessary) in an amount not less than the amount of the loan. The Corporation has not engaged in subprime residential mortgage originations.
Residential mortgage loans are subject to risk due primarily to general economic conditions, as well as periods of weak housing markets.

Commercial and Industrial — The Corporation originates commercial and industrial loans primarily to businesses located in its Market Area and surrounding areas. These loans are used for various business purposes which include short-term loans and lines of credit to finance machinery and equipment purchases, inventory, and accounts receivable. Generally, the maximum term for loans extended on machinery and equipment is based on the projected useful life of such machinery and equipment. Most business lines of credit are written on demand and may be renewed annually.
Commercial and industrial loans are generally secured with short-term assets; however, in many cases, additional collateral such as real estate is provided as additional security for the loan. Loan-to-value maximum values have been established by the Corporation and are specific to the type of collateral. Collateral values are determined using invoices, inventory reports, accounts receivable aging reports, and collateral appraisals. Appraisals on properties securing commercial and industrial loans originated by the Corporation are performed by independent appraisers.
In underwriting commercial and industrial loans, an analysis is performed to evaluate the borrower’s capacity to repay the loan, the adequacy of the borrower’s capital and collateral, as well as the economic conditions affecting the borrower. Evaluation of the borrower’s past, present and future cash flows is also an important aspect of the Corporation’s analysis. Commercial loans generally are subject to risk due primarily to the effect of general economic conditions.
Home Equity Lines of Credit — The Corporation originates home equity lines of credit primarily within the Corporation’s Market Area or with customers primarily from the Market Area. Home equity lines of credit are generated by the Corporation’s marketing efforts, its present customers, walk-in customers, and referrals.
Home equity lines of credit are secured by the borrower’s primary residence with a maximum loan-to-value of 90% and a maximum term of 20 years. In underwriting home equity lines of credit, the Corporation evaluates both the value of the property securing the loan and the borrower’s financial ability to repay the loan as agreed. The ability to repay is determined by the borrower’s employment history, current financial condition, and credit background.
Home equity lines of credit generally are subject to risk due primarily to general economic conditions, as well as periods of weak housing markets. Junior liens inherently have more credit risk by virtue of the fact that another financial institution may have a higher security position in the case of foreclosure liquidation of collateral to extinguish the debt. Generally, foreclosure actions could become more prevalent if the real estate markets are weak and property values deteriorate.
Real Estate Construction — The Corporation engages in real estate construction lending in its Market Area and surrounding areas. The Corporation’s real estate construction lending consists of commercial and residential site development loans, as well as commercial building construction and residential housing construction loans. The Corporation’s real estate construction loans are generally secured with the subject property. Terms of construction loans depend on the specifics of the project, such as estimated absorption rates, estimated time to complete, etc.
In underwriting real estate construction loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history and the reliability and predictability of cash flows generated by the project using feasibility studies, market data, etc. Appraisals on properties securing real estate construction loans originated by the Corporation are performed by independent appraisers.
Real estate construction loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions and the uncertainties surrounding total construction costs.
Consumer — The Corporation offers a variety of secured and unsecured consumer loans, including those for vehicles and mobile homes and loans secured by savings deposits. These loans are originated primarily within the Corporation’s Market Area or with customers primarily from the Market Area.
Consumer loan terms vary according to the type and value of collateral and the creditworthiness of the borrower. In underwriting consumer loans, a thorough analysis of the borrower’s financial ability to repay the loan as agreed is performed. The ability to repay is determined by the borrower’s employment history, current financial condition and credit background.
Consumer loans may entail greater credit risk than residential mortgage loans or home equity lines of credit as they are unsecured or are secured by rapidly depreciable assets such as automobiles or recreational equipment. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans.
The adoption of Topic 326 resulted in a Day 1 adjustment of $3.3 million, including an increase to the ACL of $1.6 million and a $1.6 million reserve on unfunded loan commitments recorded in the liabilities section on the Consolidated Statements of

The ACL represents an amount which, in management’s judgment, is adequate to absorb expected losses on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The ACL is measured and recorded upon the initial recognition of a financial asset. The ACL is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provision for credit losses, which is recorded as a current period operating expense.
The Corporation’s methodology for estimating the ACL includes:
Segmentation — The Corporation’s loan portfolio is segmented by loan types that have similar risk characteristics, types of collateral, and behave similarly during economic cycles.
Specific Analysis — A specific reserve analysis is applied to certain individually evaluated loans. These loans are evaluated quarterly generally based on collateral value, observable market value or the present value of expected future cash flows. A specific reserve is established if the fair value is less than the loan balance. A charge-off is recognized when the loss is quantifiable.
Quantitative Analysis — The Corporation elected to use a DCF methodology and chose unemployment rate as the driving assumption in their economic forecasts. In regards to unemployment rates, the Corporation elected to forecast economic factors over the period of the next four quarters. The Corporation utilizes relevant third-party forecasts as a basis and support for its own forecast. These forecasts are assumed to revert to the long-term historical average and utilized in the model to estimate the PD and LGD through a straight-line regression. The Corporation elected a reversion period of four quarters. The Corporation deemed four quarters to be a reasonable time period to ensure it did not include irrelevant information, but also not too short to introduce unnecessary volatility. Model assumptions include, but are not limited to, the discount rate, prepayment speeds, funding rates, PD, LGD and curtailments. The product of the PD and the LGD is the estimated loss rate, which varies over time. The estimated loss rate is applied within the appropriate periods in the cash flow model to determine the net present value. Net present value is also impacted by assumptions related to the duration between default and recovery. The reserve is based on the difference between the summation of the principal balances taking amortized costs into consideration and the summation of the net present values.
64
Table of Contents
Qualitative Analysis — Based on management’s review and analysis of internal, external and model risks, management may adjust the model output. Management reviews the peaks and troughs of the model’s calibration, considering economic forecasts to develop guardrails that serve as the basis for determining the reasonableness of the model’s output and makes adjustments as necessary. This process challenges unexpected variability resulting from outputs beyond the model’s calibration that appear to be unreasonable. Additionally, management may adjust the economic forecast if it is incompatible with known market conditions based on management’s experience and perspective.
Credit Quality Indicators
The Corporation’s portfolio risk rating analysis estimates the capability of the borrower to repay the contractual obligations of the loan agreements as scheduled or at all. The Corporation’s internal credit risk rating system is based on debt service coverage, collateral values and other factors. Non-commercial-purpose loans are defaulted to a performing classification until a loan migrates to past due status or when collection of principal or interest is considered doubtful.
Pass — Loans in this category currently show no indication of deterioration or potential problems and their loans are considered fully collectible.
Special Mention — Considered “Other Assets Especially Mentioned” these loans are currently protected, but are potentially weak. Loans in this rating category constitute an undue and unwarranted credit risk, but not to the point of justifying a classification of substandard. The credit risk may be relatively minor, yet constitutes an unwarranted risk in light of the circumstances surrounding a specific loan.
Substandard — Loans in this category are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual loans classified as substandard.
Doubtful — Loans in this category have all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors which may work to strengthen the credit, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral, and refinancing plans.
Loss — Loans classified as a loss are considered uncollectible and are charged to the ACL
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass-rated loans.
In addition, federal and state regulatory agencies, as an integral part of their examination process, periodically review the Corporation’s ACL and may require the Corporation to recognize additions to the allowance based on their judgments about information available to them at the time of their examination, which may not be currently available to management. Based on management’s comprehensive analysis of the loan portfolio and economic conditions, management believes the current level of the ACL is adequate.
Concentration of Credit Risk
Most of the Corporation’s lending activities are with customers located within South-central Pennsylvania and Northern Maryland. The types of lending in which the Corporation engages are outlined above. The Corporation’s exposure to credit risk is significantly affected by changes in the economy in those areas. Although the Corporation maintains a diversified loan portfolio, a significant portion of its customers’ ability to honor their contracts is dependent upon economic sectors for commercial real estate, including mixed use properties, office complexes, hospitality, multi-family and residential complexes and agriculture. Management evaluates each clients’ creditworthiness on an individual basis.
The types of securities in which the Corporation invests are discussed in Note 4 — “Investment Securities”.
Collateral-Dependent Loans
A loan is considered to be collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. For all classes of loans deemed collateral-dependent, the Corporation elected the practical expedient to estimate expected credit losses based on the collateral’s fair value less cost to sell. In most cases, the Corporation records a partial charge-off to reduce the collateral-dependent loan’s carrying value to the
65
Table of Contents
fair value of the collateral less cost to sell. Substantially all of the collateral supporting collateral-dependent loans consists of various types of real estate, including residential properties, commercial properties, such as retail centers, office buildings, and lodging, agriculture land, and vacant land. Changes in the fair value of the collateral for individually evaluated loans are reported as provision for credit losses or a reversal of provision for credit losses in the period of change.
Acquired Loans
Under CECL acquired loans or pools of loans that have experienced more-than-insignificant credit deterioration are deemed to be PCD loans, and are grossed-up on day one by the initial credit estimate through the ACL as opposed to a reduction in the loan’s amortized cost. The credit mark on acquired loans deemed not to be PCD loans are reflected as a reduction in the loan’s amortized cost, with an ACL and corresponding provision for credit losses recorded in the first reporting period after acquisition through current period earnings, while the net loan mark will amortize through interest income over the life of such loans. At acquisition ACNB considers several factors as indicators that an acquired loan or pool of loans has experienced more-than-insignificant credit deterioration. These factors may include, but are not limited to, loans 30 days or more past due, loans with an internal risk grade of below average or lower, or loans classified as non-accrual. Upon the adoption of CECL acquired loans from prior acquisitions that met the guidelines under ASC 310-30 (formerly known as “purchased credit-impaired”) were reclassified as PCD loans. The accretable portion of the loan mark as of adoption date continues to accrete into interest income. However, the non-accretable portion of the loan mark was added to the ACL upon adoption, and any reversals of such mark will flow through the ACL in future periods.
Transfers of Financial Assets
Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Corporation, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Corporation does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets.
Premises and Equipment
Land is carried at cost. Buildings, furniture, fixtures, equipment and leasehold improvements are carried at cost, less accumulated depreciation. Depreciation is computed principally by the straight-line method over the assets’ estimated useful lives. Normally, a building’s useful life is 40 years, except for building remodels and additions, which are depreciated over fifteen years. Bank equipment, including furniture and fixtures, is normally depreciated over three - fifteen years depending upon the nature of the purchase. Maintenance and normal repairs are charged to expense when incurred while major additions and improvements are capitalized. Gains and losses on disposals are reflected in current operations. Amortization of leasehold improvements is computed by straight line over the shorter of the assets’ useful life or the related lease term.
Leases
All leases with an initial term greater than 12 months recognize: (1) a ROU asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term; and (2) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, each measured on a discounted basis.
As a lessee, the majority of the operating lease portfolio consists of real estate leases for the Bank’s community banking offices. The operating leases have remaining lease terms of less than one year to less than twelve years, some of which include options to renew at varying durations. See Note 8 — “Leases” for additional information.
Restricted Investment in Bank Stocks
Restricted investment in bank stocks, which represents required investments in the common stock of correspondent banks, was carried at cost as of December 31, 2025 and 2024, and consists of common stock in the Atlantic Community Bankers Bank and Federal Home Loan Bank.
Management believes no impairment charge was necessary related to the restricted investment in bank stocks during 2025, 2024 or 2023.
Bank-Owned Life Insurance
The Corporation’s banking subsidiary maintains nonqualified compensation plans for selected senior officers. To fund the benefits under these plans, the Bank is the owner of single premium life insurance policies on participants in the nonqualified retirement plans. Investment in bank-owned life insurance policies was used to finance the nonqualified compensation plans and provide tax-exempt income to the Corporation.
66
Table of Contents
ASC Topic 715, Compensation—Retirement Benefits, requires a liability to be recorded during the service period when a split-dollar life insurance agreement continues after participants’ employment or retirement. The required accrued liability is based on either the post-employment benefit cost for continuing life insurance or based on the future death benefit depending on the contractual terms of the underlying agreement. The Corporation’s liability is based on the post-employment benefit cost for continuing life insurance.
Investments in Low-Income Housing Partnerships
The Corporation’s investments in low-income housing partnerships are accounted for using the “equity method” prescribed by ASC Topic 323, Investments—Equity Method. In accordance with ASC Topic 740, Income Taxes, tax credits are recognized as they become available. Any residual loss is amortized as the tax credits are received.
Goodwill and Intangible Assets
The Corporation accounts for its acquisitions using the acquisition accounting method required by ASC Topic 805, Business Combinations. Acquisition accounting requires the total purchase price to be allocated to the estimated fair values of assets and liabilities acquired, including certain intangible assets that must be recognized. Generally, this results in a residual amount in excess of the net fair values, which is recorded as goodwill.
Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. ASC Topic 350, Intangibles—Goodwill and Other, requires that goodwill is not amortized to expense, but rather that it be assessed or tested for impairment at least annually. If certain events occur which might indicate goodwill has been impaired, the goodwill is tested for impairment when such events occur. Impairment write-downs are charged to results of operations in the period in which the impairment is determined. The Corporation did not identify any impairment on the Bank’s or ACNB Insurance Services’ outstanding goodwill from its most recent goodwill impairment analysis which was completed as of November 30, 2025 using the qualitative approach. If certain events occur which indicate goodwill might be impaired between annual assessments, the goodwill would be evaluated for impairment when such events occur.
Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights. These assets that have finite lives, such as core deposit intangibles, customer lists and non-compete covenants, are amortized over their estimated useful lives and subject to periodic impairment testing. Core deposit intangibles are primarily amortized over ten years using accelerated methods. Customer lists are amortized using the straight-line method over their estimated useful lives which range from eight to fifteen years. Non-compete covenants are amortized using the straight-line method over the term of the agreement.
The fair value of customer lists intangibles was based upon an income approach which included estimated financial projections developed by the Corporation and included other fair value assumptions for attrition, present value discount rates using market participant assumptions. The fair value of the non-compete covenants intangible was based upon an income approach which compared the present value impact of various non-compete scenarios and other fair value assumptions including present value discount rates using market participant assumptions. See Note 9 — “Goodwill and Other Intangibles” for additional details.
Foreclosed Assets
Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value, less costs to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are adjusted to the fair value, less costs to sell as necessary. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets.
Derivative Financial Instruments and Hedging Activities
The Corporation is exposed to certain risks arising from both its business operations and economic conditions. The Corporation manages market risk, including interest rate risk, primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Corporation enters into derivative financial instruments to manage interest rate risk that arise from business operations.
All derivatives are recognized as either assets or liabilities in the Consolidated Statements of Condition. Until a derivative is settled, favorable changes in fair values result in unrealized gains that are recognized as assets, while unfavorable changes result in unrealized losses that are recognized as liabilities.
Interest rate-lock commitments extended to borrowers relate to the origination of residential mortgage loans. To mitigate the interest rate risk inherent in these commitments, the Corporation enters into mandatory delivery and best efforts forward commitments to sell adjustable-rate and fixed-rate residential mortgage loans (servicing released). Forward commitments and interest rate-lock commitments on residential mortgage loans are considered derivatives. Hedge accounting has not been
67
Table of Contents
applied for these derivatives. Accordingly, changes in the fair value of forward and interest rate-lock commitments are recognized in current earnings.
The Corporation executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously offset with essentially matching interest rate swaps with the Corporation’s counterparties, such that the Corporation minimizes its net risk exposure resulting from such transactions. Hedge accounting has not been applied for these derivatives. Accordingly, changes in the fair value of all such interest rate swaps are recognized in current earnings.
The Corporation applies hedge accounting, when applicable, to its derivatives used for interest rate risk management purposes. Hedge accounting is permitted only if specific criteria are met, including a requirement that a highly effective relationship exist between the derivative instrument and the hedged item, both at inception of the hedge and on an ongoing basis. The hedge accounting method depends upon whether the derivative instrument is classified as a fair value hedge (i.e. hedging an exposure related to a recognized asset or liability, or a firm commitment) or a cash flow hedge (i.e. hedging an exposure related to the variability of future cash flows associated with a recognized asset or liability, or a forecasted transaction). Changes in the fair value of effective fair value hedges are recognized in current earnings (with the change in fair value of the hedged asset or liability also recorded in earnings). Changes in the fair value of effective cash flow hedges are recognized in other comprehensive income or loss until earnings are affected by the variability in cash flows of the designated hedged item. Ineffective portions of hedge results are recognized in current earnings. Changes in the fair value of derivatives for which hedge accounting is not applied are recognized in current earnings. See Note 12 — “Derivative Financial Instruments” for additional details.
Income Taxes
The Corporation accounts for income taxes in accordance with income tax accounting guidance ASC Topic 740, Income Taxes and adopted ASU 2023-09, “Income Taxes (Topic 740)” on a prospective basis effective January 1, 2025.
Current income tax accounting guidance results in two components of income tax expense, current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Corporation determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur.
Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of the evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. The need to establish valuation allowances for deferred tax assets is assessed quarterly. In assessing the requirement for, and amount of, a valuation allowance in accordance with the more likely than not standard for all periods, the Corporation considers all positive and negative evidence related to the realization of the deferred tax assets. This assessment considers, among other matters, the generation of future profitability, the reversal of deferred tax liabilities, and tax planning strategies.
The Corporation accounts for uncertain tax positions if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more-likely-than-not means a likelihood of more than 50%; the terms examined and upon examination also include resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management’s judgment.
The Corporation recognizes interest and penalties on income taxes, if any, as a component of income tax expense. See Note 15 — “Income Taxes” for additional details.
Defined Benefit Pension Plan
Net periodic pension costs are funded based on the requirements of federal laws and regulations. The determination of net periodic pension costs is based on assumptions about future events that will affect the amount and timing of required benefit payments under the plan. These assumptions include demographic assumptions such as retirement age and mortality, a discount rate used to determine the current benefit obligation, form of payment election and a long-term expected rate of return on plan assets. Net periodic pension expense includes interest cost, based on the assumed discount rate, an expected return on plan assets, amortization of prior service cost or credit and amortization of net actuarial gains or losses. Pension expense is the net of
68
Table of Contents
service and interest cost, return on plan assets and amortization of gains and losses not immediately recognized. For additional details, see Note 14 — “Retirement Plans”.
Stock-based Compensation
Stock-based compensation awards granted, comprised of time-based restricted stock awards, are valued at fair value on the date of grant and compensation expense is recognized on a straight-line basis over the requisite service period of each award. The Company recognizes forfeitures as they occur. See Note 20 — “Stock-based Compensation” for additional details.
Advertising Costs
Costs of advertising, which are included in other expenses, are expensed when incurred.
Off-Balance Sheet Credit-Related Financial Instruments
In the ordinary course of business, the Corporation has entered into commitments to extend credit, including commitments under commercial lines of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. See Note 17 — “Commitments and Contingencies” for additional details.
Loss Contingencies
Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are such matters that will have a material effect on the financial statements. See Note 17 — “Commitments and Contingencies” for additional details.
Dividend Restriction
Pursuant to the Pennsylvania Banking Code of 1965, as amended, and the regulations of the FDIC, the Bank is required to maintain certain capital levels and is restricted in the dividends that may be paid by the bank to the holding company. In addition, pursuant to the Pennsylvania Business Corporation Law, as amended, and the rules and regulations of the Board of Governors of the Federal Reserve System, the holding company is subject to restrictions on dividends that the holding company may pay to stockholders.
Fair Value of Financial Instruments
Fair values of financial instruments are estimated using relevant market information and other assumptions. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates. See Note 13 — “Fair Value Measurements” for additional information.
Revenue Recognition
ACNB generally fully satisfies its performance obligations on its contracts with customers as services are rendered and the transaction prices are typically fixed; charged either on a periodic basis or based on activity. Because performance obligations are satisfied as services are rendered and the transaction prices are fixed, there is little judgment involved that significantly affects the determination of the amount and timing of revenue from contracts with customers. The sources of revenue for ACNB are interest income from loans and investments and noninterest income. Noninterest income is earned from various banking and financial services that ACNB offers through its subsidiaries.
Insurance Commissions — Commission income is earned based on customers transactions. The commission income is recognized when the transaction is complete.
Wealth Management — The Bank provides wealth management services under the umbrella of ACNB Wealth Management which includes trust and investment services and wealth advisory services. The trust and investment group provides a wide range of financial services, including trust administration and estate settlement services, and investment management for individuals, businesses and non-profit entities. Other services include, but are not limited to, those related to testamentary trusts, life insurance trusts, charitable remainder trusts, guardianships, power of attorney, custodial accounts and investment management and advisory accounts. In addition, ACNB Wealth Management offers retail brokerage-services through a networking agreement with a third-party provider. ACNB Wealth Management clients are located primarily within the Corporation’s Market Area.
The majority of trust and investment services revenue is earned and collected monthly, with the amount determined based on the market value of assets in each account multiplied by a fee schedule for that account. Each account has one integrated set of
69
Table of Contents
performance obligations so no allocation is required. The performance obligation is met by performing the identified fiduciary service, investment management service, or custodial service. Successful performance is confirmed by ongoing internal and regulatory control, measurement is by valuing the account assets at month-end to which a fee schedule is applied. Trust and investment services fees are contractually agreed upon with each client in instances where the client has control over the assets, and fee levels vary based mainly on the size of assets under management. Fees for trust administration or estate settlement are assessed based on the permissions granted within each governing document and in accordance with state law; estate settlement fees are generally assessed at the conclusion of estate administration.
The wealth advisory services revenue is predominantly realized through commissions generated from client transactions. Commission income is recognized when the transaction is completed, and may be paid as a single upfront payment, or as recurring income in the form of trailing commissions. A small portion of the overall revenue is derived from fee-based advisory relationships; contractually agreed upon fees are assessed based on the market value of assets in the account. Net revenue based on the terms of the networking agreement are received on a monthly basis.
Service charges on deposit accounts — Deposits are included as liabilities in the Statement of Condition. Service charges on deposit accounts include: overdraft fees; ATM fees charged for withdrawals by deposit customers from other financial institutions’ ATMs; and a variety of other monthly or transactional fees for services provided to retail and business customers, mainly associated with checking accounts. All deposit liabilities are considered to have one-day terms and therefore related fees are recognized in income at the time when the services are provided to the customers.
ATM debit card charges — The Bank issues debit cards to consumer and business customers with checking, savings or money market deposit accounts. Debit card and ATM transactions are processed via electronic systems that involve several parties. The Corporation’s debit card and ATM transaction processing is executed via contractual arrangements with payment processing networks, a processor and a settlement bank. As described above, all deposit liabilities are considered to have one-day terms and therefore interchange revenue from customers’ use of their debit cards to initiate transactions are recognized in income at the time when the services are provided and related fees received in the Corporation’s deposit account with the settlement bank.
Other — Consists of safe deposit rental income, money order fees, check cashing and cashiers’ check fees, wire transfer fees, letter of credit fees, check order income, swap fee income, trading fee income and other miscellaneous fees. These fees are largely transaction-based; therefore, the Corporation’s performance obligation is satisfied and the resultant revenue is recognized at the point in time the service is rendered. Payments for transaction-based fees are generally received immediately or in the following month by a direct charge to a customer’s account.

The Corporation evaluates and monitors the revenue streams of its various products and services and manages operations and financial performance on a consolidated basis. The Bank offers banking and wealth management services, including trust and retail brokerage. ACNB Insurance Services offers a broad range of property and casualty, life and health insurance to both commercial and consumer clients. The Corporation’s reportable segments are determined by the ACNB Board of Directors. Segment determination considers organizational structure and is consistent with the presentation of financial information to the CODM to evaluate segment performance, develop strategy, and allocate resources. The ACNB Board of Directors has determined that the Corporation has two reporting segments, the Bank and ACNB Insurance Services and considers the President and CEO of ACNB Corporation to be the CODM of both reporting segments. Key measurements of performance in the banking segment are the net interest margin and the provision for credit losses, both which indicate the Bank’s ability to manage risk, and also the Bank’s ability to grow noninterest income and manage the largest noninterest expense, salaries and employee benefits. ACNB Insurance Services is a subsidiary of the Corporation and is governed by its own Board of Directors. Key measurements of performance are revenues from commissions on insurance policies and the significant expense associated with those revenues are salaries and employee benefits. These two factors are significant in assessing the performance of the agency. The CODM evaluates the financial performance of the various business components by evaluating revenue streams, significant expenses and budget to actual results in assessing the performance of the Corporation’s segments and in order to determine the allocation of resources. See Note 22 — “Segment and Related Information” for segment-specific information and reconciliation.
Acquisition Accounting
The Corporation accounts for its mergers and acquisitions using the acquisition method of accounting, in accordance with the provisions of ASC 805 — Business Combinations. Under ASC 805, assets acquired and liabilities assumed in a business combination are at acquisition date fair value and transaction costs and restructuring costs associated with the business combination are expensed as incurred. The determination of fair values involves significant judgment regarding methods and assumptions, including discount rates, future expected cash flows, market conditions and other future events. The excess of the

merger consideration over the fair value of assets acquired and liabilities assumed, if any, is allocated to goodwill. The results of operations of the acquired entity are included in the consolidated statements of operations from the Acquisition date.
Recently Adopted Accounting Standards
In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740)”. This ASU is intended to improve the disclosures for income taxes to address requests from investors, lenders, creditors and other allocators of capital that use the financial statements to make capital allocation decisions. The amendments in ASU 2023-09 require consistent categories and greater disaggregation of information in the rate reconciliation disclosure as well as disclosure of income taxes paid disaggregated by jurisdiction. The amendments of ASU 2023-09 were effective for annual periods beginning after December 15, 2024. The Corporation adopted the amendments of ASU 2023-09 effective January 1, 2025 on a prospective basis and its adoption did not have a material impact on the Corporation’s Consolidated Financial Statements.
Accounting Standards Pending Adoption
In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses (Subtopic 220-40)”. This ASU is intended to improve the decision usefulness of expense information on public business entities’ income statements through the disaggregation of relevant expense captions in the notes to the financial statements. The amendments of ASU 2024-03 are effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and early adoption is permitted. The Corporation is currently evaluating the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s Consolidated Financial Statements.
In November 2025, the FASB issued ASU 2025-08, “Financial Instruments–Credit Losses (Topic 326): Purchased Loans”. The amendments in this ASU expand the population of acquired financial assets subject to the gross-up approach in Topic 326. Financial assets acquired with a “more-than-insignificant” deterioration of credit quality since its origination (PCD assets) and non-PCD assets are accounted for using the “gross up approach” to both populations. The amendments in this ASU are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, and early adoption is permitted. The amendments in this ASU should be applied prospectively to loans that are acquired on or after the initial application date. The Corporation is currently evaluating the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s Consolidated Financial Statements.
In November 2025, the FASB issued ASU 2025-09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements”. This ASU was issued to clarify certain aspects of the guidance on hedge accounting and to address several incremental hedge accounting issues arising from the global reference rate reform initiative. The objective of this ASU is to more closely align hedge accounting with the economics of an entity’s risk management activities. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2026, and interim periods within those annual reporting periods, and early adoption is permitted. The Corporation is currently evaluating the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s Consolidated Financial Statements.
In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270): Narrow Scope Improvements”. This ASU was issued to improve the guidance in Topic 270 by improving the navigability of the required interim disclosures and clarifying when that guidance is applicable. The amendments also provide additional guidance on what disclosures should be provided in interim reporting periods. The amendments add to Topic 270 a principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The objective of this amendment is to provide clarity on the current interim reporting requirements. The amendments in this ASU are effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, and early adoption is permitted. The Corporation is currently evaluating the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s Consolidated Financial Statements.
NOTE 2 — BUSINESS COMBINATION
Effective February 1, 2025, ACNB Corporation acquired Traditions Bancorp, Inc., 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. ACNB Bank is operating the former Traditions Bank offices as “Traditions Bank, A Division of ACNB Bank”. In connection with the Acquisition, Traditions stockholders received 0.7300 shares of ACNB Corporation common stock for each share of Traditions common stock that they owned as of the effective date and time, with cash paid in lieu of fractional shares. ACNB issued 2,035,246 shares of its common stock, and cash in exchange for fractional shares based on $41.10 per whole share of ACNB common stock. The transaction is valued at $83.8 million.
Traditions’ results of operations were included in ACNB’s results of operations beginning on February 1, 2025. Net interest income and income before income taxes for Traditions were estimated to be $31.9 million and $13.2 million, respectively, since the date of acquisition through December 31, 2025 and was included in the Corporation’s Consolidated Statements of Income.
71
ACNB’s financial results for any periods ended prior to February 1, 2025 reflect ACNB on a standalone basis. As a result, ACNB’s financial results for the year ended December 31, 2025 may not be directly comparable to prior reported periods. Merger-related costs totaled $10.7 million for the year ended December 31, 2025.
The acquisition method of accounting, in accordance with the provisions of FASB ASC Topic 805, Business Combinations, 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. Under the acquisition method of accounting, the total merger consideration is allocated to the acquired tangible and intangible assets and assumed liabilities of Traditions based on their estimated fair value as of the acquisition date of the merger. The excess of the merger consideration over the fair value of assets acquired and liabilities assumed, if any, is allocated to goodwill. ACNB recorded goodwill of $20.3 million in connection with the Acquisition, which is not amortized for financial reporting purposes, but is subject to annual impairment testing.
The total merger consideration of $83.8 million is allocated to Traditions’ tangible and intangible assets and liabilities based on their fair values as follows:

ACNB used an independent valuation specialist to assist with the determination of fair values for certain acquired assets and assumed liabilities. As permitted under GAAP, the Corporation has up to twelve months following the date of the Acquisition to finalize the fair values of the acquired assets and assumed liabilities related to the Acquisition. ACNB has determined that there were no subsequent adjustments to goodwill and that it was final as of December 31, 2025.
72
ACNB completed, shortly following the Acquisition date, the sale of approximately $98.0 million of Traditions’ investment securities with a yield of 5.03%. With the proceeds from the sale, ACNB paid off $40.2 million of FHLB borrowings with a cost of 4.73% and invested the remainder of the proceeds into investment securities with a yield of 5.07%. The acquisition accounting adjustment on the AFS securities represents the difference between the fair value of the AFS securities as of January 31, 2025 and the final proceeds received as a result of the sales. For the fair value policy see Note 13 — “Fair Value Measurements” in the Notes to Consolidated Financial Statements under Part I, Item I.
ACNB evaluated and classified the acquired loans between non-PCD or PCD. ACNB’s senior credit management team reviewed Traditions’ loan portfolio on a loan-by-loan basis to determine which loans met the definition of an ASC 326-20 PCD loan. PCD loans include loans which experienced more-than-insignificant credit deterioration since origination. PCD loans included loans on nonaccrual status, loans risk-rated pass/watch or worse, COVID-19 loan deferrals, loans more than 90 days past due and still accruing, accruing loans but were more than 60 days past due in the past, accruing loans but were more than 30 days past due more than 3 times in the past and other loans evaluated. The acquisition accounting adjustments for non-PCD loans and PCD loans were $21.6 million and $4.4 million, respectively, on the Acquisition date. Included in the acquisition accounting adjustment for loans was $635 thousand of net deferred income that served to decrease the acquisition accounting adjustment of the loans acquired.
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. The following table presents details related to the fair value of acquired PCD loans at the Acquisition date:
(In thousands)Unpaid Principal BalanceTotal Premium/(Discount)Gross Up for PCD Allowance for Credit LossesFair Value of PCD Loans
PCD accruing$140,053 $(5,359)$1,464 $136,158 
PCD non-accruing2,962 (528)— 2,434 
Total PCD Loans$143,015 $(5,887)$1,464 $138,592 
The acquisition accounting adjustment for premises and equipment was $362 thousand at the Acquisition date as a result of updated independent market-based appraisals on real estate and the write-off of obsolete fixed assets.
Pursuant to customer-related intangible assets ASC 805-20-55-13(b), ACNB, with the assistance of an independent valuation specialist, completed a core deposit intangible asset valuation that resulted in a core deposit intangible asset of $18.9 million at the Acquisition date. To establish the core deposit intangible asset, ACNB used a present value analysis that calculated the expected after-tax cash flow benefits of each acquired core deposit type versus the cost of obtaining an alternative source of funding (brokered deposits) over the expected life of each acquired core deposit type, discounted at a long-term market oriented after-tax rate of return. The core deposit intangible asset is amortized based on the sum-of-the-years digits method over the expected life of 10 years.
The acquisition accounting adjustment for other assets was $1.4 million at the Acquisition date driven primarily by a net deferred tax position for each acquisition accounting adjustment. The acquisition accounting adjustment for deposits was $215 thousand at the Acquisition date as a result of acquisition accounting adjustments on certificates of deposits using a present value approach that represents the present value of the certificates’ expected contractual payments discounted by market rates for similar certificates of deposits. The acquisition accounting adjustment for the allowance for unfunded commitments was $852 thousand as a result of applying ACNB’s existing policies, procedures and methodologies in calculating the allowance for Traditions’ unfunded commitments. The acquisition accounting adjustment for other liabilities was $41 thousand at the Acquisition date as a result of the write-off of unearned letter of credit fees.
The following table presents supplemental pro forma information for the years ended December 31 as if the acquisition had occurred January 1, 2024. The unaudited pro forma information includes acquisition accounting adjustments for interest income on loans acquired, amortization of core deposit intangibles arising from the transaction, depreciation expense on property acquired, interest expense of deposits acquired, and the related income tax effects. The pro forma financial information is not necessarily indicative of the results of operations that would have occurred had the transactions been affected on the assumed dates. In addition, the unaudited proforma information excludes merger-related expenses and the provision for credit losses on non-PCD loans at the Acquisition date, and does not reflect management’s estimate of any revenue-enhancing opportunities or anticipated cost savings as a result of the integration:

The Company evaluates AFS debt securities for impairment in unrealized loss positions at each measurement date to determine whether the decline in the fair value below the amortized cost basis is due to credit-related factors or noncredit-related factors. In estimating credit events, management considers whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before anticipated recovery or if it does not expect to recover the entire amortized cost basis. There was no impairment on AFS debt securities as of December 31, 2025 and 2024. The Company evaluates HTM debt securities for expected credit losses at each measurement date to determine the ACL. The Corporation's ACL on its HTM investment securities was de minimis as of December 31, 2025 and 2024.

Loan Modifications
The Corporation evaluates all loan restructurings according to the accounting guidance for loan modifications to determine if the restructuring results in a new loan or a continuation of the existing loan. Loan modifications to borrowers experiencing financial difficulty that result in a direct change in the timing or amount of contractual cash flows include situations where there is principal forgiveness, interest rate reductions, other-than-insignificant payment delays, term extensions, and combinations of the above. Therefore, the disclosures related to loan restructurings are only for modifications that directly affect cash flows.

Allowance for Credit Losses
The Corporation maintains an ACL at a level determined to be adequate by management to absorb expected credit losses associated with the Corporation’s financial instruments over the life of those instruments as of the balance sheet date. The ACL consists of loans evaluated collectively and individually for expected credit losses. The Corporation considers the performance of the loan portfolio and its impact on the ACL and does not assign internal risk ratings to smaller balance, homogeneous loans such as certain residential mortgage, home equity lines of credit, construction loans to individuals secured by residential real estate and consumer loans. For these loans, the Corporation evaluates credit quality based on the aging status of the loan and designates as performing and nonperforming.

ACNB Corporation is a limited partner in two partnerships, whose purpose is to develop, manage and operate residential low-income properties. At December 31, 2025 and 2024, the carrying value of these investments was $751 thousand and $877 thousand, respectively.
NOTE 8 — LEASES
The Corporation enters into noncancellable lease arrangements primarily for some of its community banking offices. Certain lease arrangements contain clauses requiring increasing rental payments over the lease term, which are generally contractually stipulated. Many of these lease arrangements provide the Corporation with the option to renew the lease arrangement after the initial lease term. These options are included in determining the lease term used to establish the right-of-use assets and lease liabilities, when it is reasonably certain the Corporation will exercise its renewal option. As most of the Corporation’s leases do
84
not have a readily determinable implicit rate, the incremental borrowing rate is primarily used to determine the discount rate for purposes of measuring the right-of-use assets and lease liabilities. The Corporation’s lease arrangements do not contain any material residual value guarantees or material restrictive covenants. The increases in ROU assets and lease liabilities are due to assumed leases as a result of the Acquisition.
The following ROU assets and lease liabilities are reported within the Consolidated Statements of Condition as follows:

Borrowings with original maturities of one year or less are classified as short-term. Securities sold under repurchase agreements are comprised of customer repurchase agreements, which are sweep accounts with next-day maturities utilized by larger commercial customers to earn interest on their funds. Securities are pledged to these customers in an amount at least equal to the outstanding balance. Under an agreement with the FHLB, the Bank has short-term borrowing capacity included within its maximum borrowing capacity. All FHLB advances are collateralized by a security agreement covering qualifying loans, which consist of 1-4 family mortgage loans and other real estate secured loans. In addition, all FHLB advances are secured by the FHLB capital stock owned by the Bank having a par value of $13.9 million at December 31, 2025. The Bank also has unsecured lines of credit that total $192.0 million with correspondent banks for overnight federal funds borrowings. There were no advances on these lines at December 31, 2025 and 2024. The Corporation maintains a $5.0 million unsecured line of credit with a correspondent bank and the Corporation guarantees a note related to a $1.5 million commercial line of credit with a correspondent bank for ACNB Insurance Services. There were no advances on these lines at December 31, 2025 and 2024.

The long-term FHLB advances are collateralized by the assets defined in the security agreement, which included loans totaling $1.85 billion, and FHLB capital stock described previously. Based on this collateral and ACNB’s holding of FHLB stock, ACNB is eligible to borrow up to $1.29 billion, of which $1.01 billion was available at December 31, 2025.
The trust preferred subordinated debt is comprised of debt securities issued by FCBI in December 2006 and assumed by ACNB Corporation through the acquisition of FCBI. FCBI completed the private placement of an aggregate of $6.0 million of trust
87
preferred securities. The interest rate on the subordinated debentures is adjusted quarterly to 163 bps over three-month CME Term SOFR plus applicable tenor spread adjustment. On December 16, 2025 the most recent interest rate reset date, the interest rate was adjusted to 5.61% for the period ending March 15, 2026. The trust preferred securities mature on December 15, 2036, and may be redeemed at par, at the Corporation’s option, on any interest payment date. The trust preferred subordinated debt is considered Tier 1 capital for the consolidated capital ratios.
On March 30, 2021, ACNB entered into Subordinated Note Purchase Agreements with certain Purchasers pursuant to which the Corporation sold and issued $15.0 million in aggregate principal amount of its 4.00% fixed-to-floating rate Subordinated Notes due March 31, 2031. The Subordinated Notes bear interest at a fixed rate of 4.00% per year, from and including March 30, 2021 to, but excluding, March 31, 2026 or earlier redemption date. From and including March 31, 2026 to, but excluding the maturity date or earlier redemption date, the interest rate will reset quarterly at a variable rate equal to the then current 90-day average SOFR plus 329 bps. As provided in the Subordinated Notes, the interest rate on the Subordinated Notes during the applicable floating rate period may be determined based on a rate other than the 90-day average SOFR. The Subordinated Notes were issued by the Corporation to the Purchasers at a price equal to 100% of their face amount. The Subordinated Notes have a stated maturity of March 31, 2031, are redeemable by the Corporation at its option, in whole or in part, on or after March 30, 2026, and at any time upon the occurrences of certain events. The Subordinated Notes are considered Tier 2 capital for the consolidated capital ratios.
On February 27, 2026, ACNB notified holders that the Company will redeem on March 31, 2026 all of the Company’s outstanding 4.00% fixed-to-floating rate subordinated notes due March 31, 2031, having an aggregate principal amount of $15.0 million in accordance with the terms of the Subordinated Notes. The total redemption price will be 100% of the aggregate principal amount of the Subordinated Notes, plus interest accrued and unpaid to March 31, 2026.
On March 12, 2026, ACNB issued $15.0 million of 5.875% fixed-to-floating rate subordinated notes due March 15, 2036 at par. The notes are callable at par plus accrued interest on March 15, 2031, in accordance with the terms of the $15.0 million subordinated notes due March 31, 2036.

NOTE 13 — FAIR VALUE MEASUREMENTS
Fair value is the exchange price that would be received to sell the asset or transfer the liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions.
Fair value measurement establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2 — Quoted prices for similar assets or liabilities in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3 — Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).
An asset or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The valuation techniques used to measure fair value for the items in the preceding tables are as follows:
Equity securities — The fair value of equity securities with readily determinable fair values is recorded on the Consolidated Statements of Condition, with realized and unrealized gains and losses reported in noninterest income on the Consolidated Statements of Income. They are classified as Level 1 assets.
Available for sale investment securities — Included in this asset category are debt and pass through securities. Level 2 investment securities are valued by a third-party pricing service. The pricing service uses pricing models that vary based on asset class and incorporate available market information, including quoted prices of investment securities with similar characteristics. Because many fixed income securities do not trade on a daily basis, pricing models use available information, as applicable, through processes such as benchmark yield curves, benchmarking of like securities, sector groupings and matrix pricing. Standard market inputs include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data, including market research publications. For certain security types, additional inputs may be used, or some of the standard market inputs may not be applicable.
91
•     U.S. Government and agencies — Fair values are determined by a third-party pricing service, as detailed above. These debt securities are classified as Level 2.
•     Collateralized mortgage obligations, Mortgage-backed securities and State and Municipal Securities — Fair values are determined by a third-party pricing service, as detailed above. These debt securities are classified as Level 2.
•     Corporate bonds — This category consists of subordinated and senior debt issued by financial institutions and the fair values for these corporate debt securities are determined by a third-party pricing service, as detailed above. They are classified as Level 2 investments.
Loans held for sale — This category includes mortgage loans held for sale that are measured at fair value utilizing Level 2 measurements. Fair values are measured as the price that secondary market investors were offering for loans with similar characteristics.
Derivative financial instruments — Derivative financial instruments include interest rate lock commitments, forward commitments and interest rate derivatives. The fair value of interest rate lock commitments is derived from the value of the underlying loans, adjusted for changes in market interest rates relative to the committed rate. The fair value of forward commitments is based on quoted prices for mortgage-backed securities with similar characteristics. The fair value of interest rate derivatives are based upon broker quotes. The fair value of both the assets and the related liabilities are determined in the same manner and are all classified as Level 2 assets.
Individually evaluated loans — This category consists of loans that were individually evaluated for impairment and have a specific reserve. They are classified as Level 3 assets.
Foreclosed assets held for resale — This category consists of foreclosed assets that are held for resale and classified as Level 3 assets, for which the fair values were based on estimated selling prices less estimated selling costs for similar assets in active markets.

__________________________________________________
1 Fair value is generally determined through management’s estimate or independent third-party appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable.
2 Appraisals may be adjusted downward by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range of liquidation expenses and other appraisal adjustments are presented as a percentage of the appraisal. Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received, and/or age of the appraisal.
The following information should not be interpreted as an estimate of the fair value of the entire Corporation since a fair value calculation is only provided for a limited portion of the Corporation’s assets and liabilities. Management uses its best judgment in estimating the fair value of the Corporation’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Corporation could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective reporting dates and have not been reevaluated or updated for purposes of these Consolidated Financial Statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period end. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Corporation’s disclosures and those of other companies may not be meaningful.

NOTE 14 — RETIREMENT PLANS
Defined-Contribution 401(k) Retirement Plans
The Bank maintains a 401(k) retirement plan for the benefit of eligible employees. The plan allows employees to contribute up to 100% of their compensation subject to certain limits based on federal tax laws. The plan also provides for the Bank to match 100% of the employee’s contribution to the plan up to 3% of the employee’s compensation, plus 50% the employee’s contribution to the plan on the next 2% of the employee’s compensation. Matching contributions vest immediately to the employee. Bank contributions to the plan were $1.3 million, $1.1 million and $999 thousand for 2025, 2024 and 2023, respectively, and were included as a component of salaries and employee benefits expense.
ACNB Insurance Services has a similar but separate 401(k) plan with the match of 6% for non-highly compensated employees and 3% match for highly compensated employees. ACNB Insurance Services contributions to the plan for 2025, 2024 and 2023 were $211 thousand, $202 thousand and $183 thousand, respectively, and were included as a component of salaries and employee benefits expense.
Nonqualified Compensation Plans
The Bank maintains nonqualified compensation plans for selected senior officers. The estimated present value of future benefits is accrued over the period from the effective date of the agreements until the expected retirement dates of the individuals. The balance accrued for these plans included in other liabilities as of December 31, 2025 and 2024, totaled $6.5 million and $5.1 million, respectively. The annual expense included in salaries and employee benefits expense totaled $886 thousand, $946 thousand and $953 thousand during the years ended December 31, 2025, 2024 and 2023, respectively. To fund the benefits under these plans, the Bank is the owner of single premium life insurance policies on participants in the nonqualified retirement plans.
Defined Benefit Pension Plan
The Bank has a non-contributory, defined benefit pension plan. No employee hired after March 31, 2012 is eligible to participate in the plan. Retirement benefits are a function of both years of service and compensation. As of the last annual census, the Bank had a combined 324 active, vested terminated and retired persons in the plan. The funding policy is to contribute annually the amount that is sufficient to meet the minimum funding requirements set forth by ERISA. The Bank uses a measurement date of December 31 for this plan.

The Corporation’s overall investment strategy is to achieve a mix of investments to meet the long-term rate of return assumption and near-term pension obligations with a diversification of asset types, fund strategies and fund managers. The mix of investments is adjusted periodically by retaining an advisory firm to recommend appropriate allocations after reviewing the Corporation’s risk tolerance on contribution levels, funded status and plan expense, and any applicable regulatory requirements. The weighted-average assets’ allocation in the following table represents the Corporation’s conclusion on the appropriate mix of investments. The specific investment vehicles are institutional separate accounts from a variety of fund managers which are regularly reviewed by the Corporation for acceptable performance.

Based on the Corporation's history of prior earnings and its expectations of the future, it is anticipated that operating income and the reversal pattern of its temporary differences will, more likely than not, be sufficient to realize the benefits of these net deferred tax assets and has not recorded any valuation allowances on its deferred tax assets as of December 31, 2025 and 2024.
The Corporation and its subsidiaries are subject to U.S. federal income tax as well as income tax of the states for which income is derived. The Corporation is no longer subject to examination by taxing authorities for years before 2021.
The Corporation follows accounting guidance related to accounting for uncertainty in income taxes. Under the “more likely than not” threshold guidelines, the Corporation believes no significant uncertain tax positions exist, either individually or in the aggregate, that would give rise to the non-recognition of an existing tax benefit. The Corporation did not have any material uncertain tax positions at December 31, 2025 or 2024.
NOTE 16 — REGULATORY MATTERS
Regulatory Capital Requirements
The Corporation and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s Consolidated Financial Statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain OBS items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
Minimum regulatory capital requirements established by Basel III rules require the Corporation and the Bank to:
•Meet a minimum Tier 1 leverage capital ratio of 4.0% of average assets;
•Meet a minimum Common Equity Tier 1 capital ratio of 4.5% of risk-weighted assets;
98
•Meet a minimum Tier 1 capital ratio of 6.0% of risk-weighted assets;
•Meet a minimum Total capital ratio of 8.0% of risk-weighted assets;
•Maintain a “capital conservation buffer” of 2.5% above the minimum risk-based capital requirements, which must be maintained to avoid restrictions on capital distributions and certain discretionary bonus; and,
•Comply with the definition of capital to improve the ability of regulatory capital instruments to absorb losses.
Management believes, as of December 31, 2025, that the Corporation and the Bank meet all capital adequacy requirements to which they are subject. There are no subsequent conditions or events that management believes have changed the Bank’s category.

Dividend Restrictions
Dividend payments by the Bank to the Corporation are subject to certain legal and regulatory limitations. As of December 31, 2025 $55.5 million of undistributed earnings of the Bank, included in consolidated retained earnings, was available for distribution to the Corporation as dividends without prior regulatory approval. Additionally, dividends paid by the Bank to the Corporation would be prohibited if the effect thereof would cause the Bank’s capital to be reduced below applicable minimum capital requirements. The Corporation is subject to dividend restrictions as provided by Pennsylvania law.
NOTE 17 — COMMITMENTS AND CONTINGENCIES
Commitments
The Corporation is a party to financial instruments with OBS risk in the normal course of business to meet the financing needs of its customers. These financial instruments consist primarily of commitments to extend credit (typically mortgages and
99
commercial loans) and, to a lesser extent, standby letters of credit. To varying degrees, these instruments involve elements of credit and interest rate risk in excess of the amount recognized on the Consolidated Statements of Condition.
The Corporation’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on balance sheet instruments. The Corporation does not anticipate any material losses from these commitments.
Commitments to extend credit, including commitments to grant loans and unfunded commitments under lines of credit, are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Corporation evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation upon extensions of credit, is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable, inventory, property and equipment and income-producing commercial properties. On loans secured by real estate, the Corporation generally requires loan to value ratios of no greater than 80%.
Standby letters of credit are conditional commitments issued by the Corporation to guarantee the performance of a customer to a third-party. Those guarantees are primarily issued to support public and private borrowing arrangements and similar transactions. The terms of the letters of credit vary and may have renewal features. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. The Corporation generally holds collateral and/or personal guarantees supporting those commitments for which collateral is deemed necessary. Management believes that the proceeds obtained through a liquidation of such collateral and the enforcement of guarantees would be sufficient to cover the maximum potential amount of future payments required under the corresponding guarantees.
The Corporation maintains a $5.0 million unsecured line of credit with a correspondent bank. The Corporation guarantees a note related to a $1.5 million commercial line of credit with a correspondent bank, with normal terms and conditions for such a line, for ACNB Insurance Services, the borrower. The commercial line of credit is for general working capital needs as they arise by ACNB Insurance Services. The liability is recorded for the net drawn amount of this line, no further liability is recorded for the remaining line as to the guarantor’s obligation as the guarantor would have full recourse from all assets of its wholly-owned subsidiary. There were no advances on these lines at December 31, 2025 and 2024.
The Corporation has not been required to perform on any financial guarantees, and has not incurred any losses on its commitments, during the past three years.
A summary of the Corporation’s commitments at December 31 were as follows:

Commitments to extend credit$566,837 $372,839 
Standby letters of credit24,387 15,103 
Contingencies
The Corporation is subject to claims and lawsuits which arise primarily in the ordinary course of business. Based on information presently available and advice received from legal counsel representing the Corporation in connection with any such claims and lawsuits, it is the opinion of management that the disposition or ultimate determination of any such claims and lawsuits will not have a material adverse effect on the consolidated financial position, consolidated results of operations or liquidity of the Corporation.

Dividend Reinvestment and Stock Purchase Plan
In 2011, the Corporation offered stockholders the opportunity to participate in the ACNB Corporation Dividend Reinvestment and Stock Purchase Plan. The plan provides registered holders of ACNB Corporation common stock with a convenient way to purchase additional shares of common stock by permitting participants in the plan to automatically reinvest cash dividends on all or a portion of the shares owned and to make quarterly voluntary cash payments under the terms of the plan. Participation in the plan is voluntary, and there are eligibility requirements to participate in the plan. On August 8, 2025, ACNB replaced the 2011 ACNB Corporation Dividend Reinvestment and Stock Purchase Plan with the 2025 Dividend Reinvestment and Stock Purchase Plan, reserving 500,000 shares for issuance. During 2025, 2024 and 2023, 23,015, 21,750 and 20,361 shares, respectively, were issued under these plans with proceeds in the amount of $1.2 million, $832 thousand and $721 thousand, respectively.
Share Repurchase Plan
On June 18, 2025, the Corporation announced that the Board of Directors approved a plan to repurchase, in open market transactions at prevailing market prices, up to 314,000 shares, or approximately 3% of the outstanding shares of ACNB’s common stock. This common stock repurchase program replaced and superseded any and all earlier announced repurchase plans. There were 116,929 shares purchased under this plan during the year ended December 31, 2025.
101
On October 24, 2022, the Corporation announced that the Board of Directors approved on October 18, 2022, a plan to repurchase, in open market and privately negotiated transactions, up to 255,575, or approximately 3%, of the outstanding shares of the Corporation’s common stock. The plan was replaced by the plan announced on June 18, 2025. There were 215,372 treasury shares purchased under this plan through June 30, 2025.
Stock Incentive Plan
On May 1, 2018, stockholders approved and ratified the Omnibus Plan, effective as of March 20, 2018, in which awards shall not exceed, in the aggregate, 400,000 shares of common stock, plus any shares that are authorized, but not issued, under the Restricted Stock Plan. The Restricted Stock Plan expired by its own terms after 10 years on February 24, 2019, and no further shares may be issued under the plan. The remaining 174,055 shares under the Restricted Stock Plan were transferred to the Omnibus Plan. As of December 31, 2025, there were 185,413 shares issued under the Omnibus Plan and 388,642 shares reserved for future grants.
NOTE 20 — STOCK-BASED COMPENSATION
The Corporation grants equity awards to employees in the form of restricted stock awards under its ACNB Corporation 2018 Omnibus Stock Incentive Plan. The fair value of equity awards granted to employees is recognized as compensation expense over the vesting period of the stock issued.

EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES
The Corporation carried out an evaluation, under the supervision and with the participation of its management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Corporation’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Corporation (including its consolidated subsidiaries) required to be included in periodic SEC filings.
Based on the evaluation of the effectiveness of the design and operation of the disclosure controls and procedures, the Chief Executive Officer and Chief Financial Officer concluded that the Corporation’s disclosure controls and procedures were effective as of December 31, 2025. The Corporation believes that the accompanying Consolidated Financial Statements fairly present the financial condition and results of operations for the fiscal years presented in this report on Form 10-K.
CHANGES IN INTERNAL CONTROLS OVER FINANCIAL REPORTING
There were no changes made to the Corporation’s internal control over financial reporting during the most recent fiscal quarter that materially affected, or would be reasonably likely to materially affect, the Corporation’s internal control over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
ACNB is responsible for the preparation, integrity, and fair presentation of the Consolidated Financial Statements included in this annual report. The Consolidated Financial Statements and notes included in this annual report have been prepared in conformity with GAAP and, as such, include some amounts that are based on management’s best estimates and judgments.
ACNB’s management is responsible for establishing and maintaining effective internal control over financial reporting. The system of internal control over financial reporting, as it relates to the Consolidated Financial Statements, is evaluated for effectiveness by management and tested for reliability through a program of internal audits and management testing and review. Actions are taken to correct potential deficiencies as they are identified. Any system of internal control, no matter how well designed, has inherent limitations, including the possibility that a control can be circumvented or overridden and misstatements due to error or fraud may occur and not be detected. Also, because of changes in conditions, internal control effectiveness may vary over time. Accordingly, even an effective system of internal control will provide only reasonable assurance with respect to financial statement preparation.
The Board of Directors of ACNB, through its Audit Committee, meets regularly with management, internal auditors and the independent registered public accounting firm. The Audit Committee provides oversight to ACNB by reviewing audit plans and results, and evaluates management’s actions for internal control, accounting and financial reporting matters. The internal auditors and independent registered public accounting firm have direct and confidential access to the Audit Committee to discuss the results of their examinations.
Management assessed the effectiveness of ACNB’s internal control over financial reporting as of December 31, 2025. In making this assessment, it used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in its Internal Control—Integrated Framework (2013). Based on our assessment, management concluded that as of December 31, 2025, ACNB’s internal control over financial reporting is effective and meets the criteria of the Internal Control—Integrated Framework (2013).
ACNB’s independent registered public accounting firm, which audited the Consolidated Financial Statements included in this annual report, has issued an attestation report on ACNB’s internal control over financial reporting as of December 31, 2025 that appears in Item 8 of this Form 10-K and is incorporated into this item by reference.
