Description of ACNB Corporation

ACNB Corporation was formed in 1982 and became the holding company for the banking subsidiary in 1983. ACNB Corporation’s wholly-owned banking subsidiary is ACNB Bank, a Pennsylvania state-chartered bank and trust company, formerly Adams County National Bank.

We have not authorized anyone to provide you with information about the Corporation; therefore, you should rely only on the information contained in this document or on documents to which we refer you. Although we believe we have provided you with all the information helpful to you in your decision to vote, events may occur at ACNB Corporation subsequent to printing this proxy statement that might affect your decision or the value of your stock.

VOTING PROCEDURES

Solicitation and Voting of Proxies

The Board of Directors solicits this proxy for use at the Corporation’s 2025 Annual Meeting of Shareholders. The Corporation’s directors and officers and ACNB Bank employees may solicit proxies in person or by telephone, facsimile, email or other similar electronic means without additional compensation. The Corporation will pay the cost of preparing, assembling, printing, mailing and soliciting proxies and any additional material that the Corporation sends to its shareholders. The Corporation will make arrangements with brokerage firms and other custodians, nominees and fiduciaries to forward proxy solicitation materials to the beneficial owners of stock held by these entities, as well as will reimburse these third parties for their reasonable forwarding expenses. This proxy statement and the related proxy card are being distributed on or about March 31, 2025.

Shareholders of record at the close of business on March 13, 2025 (the annual meeting record date), are entitled to vote at the meeting. The Corporation’s records show that, as of the annual meeting record date, 10,542,731 shares of the Corporation’s common stock, par value $2.50 per share, were outstanding. On

TABLE OF CONTENTS

all matters to come before the annual meeting, shareholders may cast one (1) vote for each share held. Cumulative voting rights do not exist with respect to the election of directors.

You may vote your shares by completing and returning a written proxy card or voting by internet or telephone. You may also vote in person at the meeting. Submitting your voting instructions by returning a proxy card, internet or telephone will not affect your right to attend the meeting and vote, if you later decide to attend in person.

If your shares are registered directly in your name with ACNB Corporation’s transfer agent, Continental Stock Transfer & Trust Company, you are considered, with respect to those shares, the shareholder of record, and these proxy materials are being sent directly to you by the Corporation. As the shareholder of record, you have the right to grant your voting proxy directly to the proxyholders or to vote at the meeting. The Corporation has provided a proxy card, as well as instructions to vote by internet or telephone, for your use.

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in street name, and these proxy materials are being forwarded to you by your broker or nominee which is considered, with respect to those shares, the shareholder of record. As the beneficial owner, you have the right to direct your broker or nominee how to vote and you are also invited to attend the meeting with proper identification as to your beneficial ownership. However, because you are not the shareholder of record, you may not vote your street name shares at the meeting, unless you obtain a proxy executed in your favor from the holder of record. Your broker or nominee has enclosed a voting instruction card for you to use in directing the broker or nominee how to vote your shares.

By properly completing a proxy, you appoint Kimberly S. Chaney and Scott L. Kelley as proxyholders to vote your shares, as indicated on the proxy card. Any signed proxy card or vote by internet or telephone not specifying to the contrary will be voted FOR:

Electing four (4) Class 1 Directors to serve for terms of three (3) years and until their successors are elected and qualified;

Approving the non-binding vote on executive compensation; and,

Ratifying the selection of Crowe LLP as ACNB Corporation’s independent registered public accounting firm.

You may revoke your written proxy by delivering written notice of revocation to the Secretary of the Corporation, by executing a later dated proxy and giving written notice of the revocation, or by voting again by internet or telephone, at any time before the proxy is voted at the meeting. Proxyholders will vote shares represented by proxies on the accompanying proxy card, if properly signed and returned, or by internet or telephone in accordance with instructions from shareholders.

Although the Board of Directors knows of no other business to be presented, in the event that any other matters are properly brought before the meeting, any proxy given pursuant to this solicitation will be voted in accordance with the recommendations of the Board of Directors.

Quorum and Vote Required for Approval

As of the close of business on March 13, 2025, the Corporation had 10,542,731 shares of common stock, par value $2.50 per share, outstanding.

Under Pennsylvania law and ACNB Corporation’s Bylaws, the presence of a quorum is required for each matter to be acted upon at the meeting. A majority of the outstanding shares of common stock, represented in person or by proxy, constitutes a quorum. Votes withheld and abstentions are counted in determining the presence of a quorum for a particular matter. Broker non-votes are not considered present and voting on a particular matter as to which the broker withheld authority and, therefore, not counted as a vote cast on that matter. Each share is entitled to one (1) vote on all matters submitted to a vote of the shareholders. All matters to be voted upon by the shareholders require the affirmative vote of a majority of shares voted, in person or by proxy, at the annual meeting, except in cases where the vote of a greater number of shares is required by law or under ACNB Corporation’s Articles of Incorporation or Bylaws. In

TABLE OF CONTENTS

the case of the election of directors, the candidates receiving the highest number of votes are elected. Shareholders are not entitled to cumulate votes for the election of directors.

If a quorum is present, approving the non-binding proposal on executive compensation and ratifying the independent registered public accounting firm for the year ending December 31, 2025 requires the affirmative “FOR” vote of a majority of all votes cast, in person or by proxy. Abstentions and broker non-votes are not deemed to constitute “votes cast” and, therefore, do not count either for or against the proposals.

If a quorum is present, the shareholders will elect the nominees for director receiving the highest number of “FOR” votes cast by those shareholders entitled to vote for the election of directors. The proxyholders will not cast votes for or against any director nominees when the broker withheld authority.

GOVERNANCE OF THE CORPORATION

Our Board of Directors believes that the purpose of corporate governance is to ensure that we maximize shareholder value in a manner consistent with legal requirements and the highest standards of integrity. The Board has adopted and adheres to corporate governance practices which the Board and executive management believe promote this purpose, are sound, and represent best practices. We continually review these governance practices, Pennsylvania law (the state in which we are incorporated), rules and listing standards of The Nasdaq Stock Market, Securities and Exchange Commission (SEC) regulations, as well as best practices suggested by recognized governance authorities. Currently, our Board of Directors has fourteen (14) members. Under the SEC and Nasdaq standards for independence, except for Messrs. Draganosky and Seibel, all non-employee directors and nominees meet the standards for independence. This constitutes more than a majority of our Board of Directors. Mr. Draganosky is not independent because he has entered into and received certain compensation and benefits from the Corporation related to a separation and non-competition agreement. Mr. Seibel is not independent because he is the brother of Douglas A. Seibel, Executive Vice President/Chief Lending & Revenue Officer of ACNB Bank. Only independent directors serve on our Audit Committee, Compensation Committee, and Nominating Committee.

Leadership Structure

The Corporation chooses to separate the roles of Chairman and President & Chief Executive Officer. The President & Chief Executive Officer is responsible for implementing the strategic direction of the Corporation, as determined by the Board of Directors, and for the day-to-day leadership and performance of the Corporation. The Chairman oversees the agenda for and presides over Board of Director meetings, as well as provides leadership to the Board and facilitates communication between the Board of Directors and executive management. The Corporation’s Chairman of the Board is considered independent under the SEC and Nasdaq standards for independence.

Risk Oversight

The Board of Directors has a role in overseeing the Corporation’s risks as a whole and at the committee level. The Audit Committee is primarily responsible for overseeing the risks the Corporation faces on behalf of the Board of Directors. In doing so, the Audit Committee works closely with the Corporation’s Chairman of the Board, President & Chief Executive Officer, and ACNB Bank’s Chief Risk Officer, as well as with other members of management with respect to matters relating to risk management. The Audit Committee receives reports on risk management and the processes in place to monitor and control such exposures. The Audit Committee may also receive updates, from time to time, between meetings from management relating to risk oversight matters. The Audit Committee provides updates on its risk management activities to the full Board of Directors via the committee’s meeting minutes. Further, members of management may make presentations on risk management to the full Board of Directors or another committee of the Board of Directors.

In addition to the Audit Committee, other committees of the Board of Directors consider the risks within their areas of responsibility. For example, the Compensation Committee considers the risks that may be implicated by the Corporation’s compensation practices. Also, the Executive Committee assesses the risks associated with the Corporation’s executive management succession plan. It is the role of the full Board of Directors, however, to consider the risks associated with the Corporation’s strategic plan and its implementation.

TABLE OF CONTENTS

Director Independence

In determining each director’s and nominee’s independence, the Board of Directors considered loan transactions between ACNB Bank and the individuals, their family members, and businesses with which they are associated. The table below includes a description of other categories or types of transactions, relationships or arrangements considered by the Board (in addition to those listed above and those transactions set forth under “Transactions with Directors and Executive Officers” below) in reaching its determination that the directors are independent.

Name	Independent	Other Transactions/ Relationships/Arrangements

Scott L. Kelley	Yes	None
James J. Lott	Yes	None
Donna M. Newell	Yes	None

Shareholder Communications

The Board of Directors has formal shareholder communications processes for the submission of shareholder proposals and nomination of directors, as described below. In addition, shareholders may contact any member of the Board personally, by telephone or by written correspondence including email. Written communications received by the Corporation from shareholders are shared with the full Board as deemed appropriate.

TABLE OF CONTENTS

Submission of Shareholder Proposals and Other Nominations

In order for a shareholder proposal (other than director nominations) to be considered for inclusion in ACNB Corporation’s proxy statement for next year’s annual meeting, the written proposal must be received by the Corporation no later than December 1, 2025. Proposals may be sent to the Secretary of ACNB Corporation, at 16 Lincoln Square, P.O. Box 3129, Gettysburg, Pennsylvania 17325.

All proposals must comply with SEC regulations regarding the inclusion of shareholder proposals in company-sponsored proxy materials. If a shareholder proposal is submitted to the Corporation after December 1, 2025, it is considered untimely; and, although the proposal may be considered at the annual meeting, the Corporation is not obligated to include it in the 2026 proxy statement.

In addition to satisfying the foregoing requirements under ACNB Corporation’s Bylaws, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the Corporation’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934, as amended, no later than March 7, 2026. However, if the date of the 2026 Annual Meeting is changed by more than thirty (30) calendar days from the anniversary date of the 2025 Annual Meeting, then notice must be provided by the later of sixty (60) calendar days prior to the date of the 2026 Annual Meeting or the tenth (10th) calendar day following the day on which public announcement of the date of the 2026 Annual Meeting is first made.

Employee Code of Ethics

Since May 1994, ACNB Bank, formerly Adams County National Bank, has had a Conflict of Interest/Code of Ethics. In 2003, as required by law and regulation, the Corporation’s Board of Directors adopted a Code of Ethics which is applicable to our directors, officers and employees, and which has been amended as necessary from time to time.

The Code of Ethics encourages individuals to report any conduct that they believe in good faith to be an actual or apparent violation of the Code of Ethics to ACNB Corporation’s Chief Governance Officer. The Code of Ethics is available under the Governance Documents section of the ACNB Corporation Investor Relations website at investor.acnb.com.

Anti-Hedging/Pledging Policy

Pursuant to the Corporation’s policy, directors and executive officers are prohibited from entering into hedging transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity securities. Further, directors and executive officers are prohibited from holding our equity securities in a margin account or pledging our equity securities as collateral for a loan.

Insider Trading Policies and Procedures

The Corporation maintains an Insider Trading Policy Statement that governs the purchase, sale, and/or other dispositions of its securities by directors, officers and employees. The Corporation believes that the Insider Trading Policy Statement is reasonably designed to promote compliance with insider trading laws, rules and regulations, and Nasdaq listing standards. The Insider Trading Policy Statement is available under the Governance Documents section of the ACNB Corporation Investor Relations website at investor.acnb.com.

ELECTION OF DIRECTORS

Nomination of Directors

The Corporation has a standing Nominating Committee with a charter. Recommendations to the Board of Directors as to the nominees for election as directors at the Annual Meeting of Shareholders are provided by the Nominating Committee. The Nominating Committee will consider shareholder-recommended nominees for director, and shareholders who desire to propose an individual for consideration by the Board of Directors as a nominee for director should submit a recommendation in writing to the Secretary of the Corporation in compliance with the requirements of Article II, Sections 202, 203 and 207(b), of the Corporation’s Bylaws. Any shareholder who intends to nominate a candidate for election to the Board of

TABLE OF CONTENTS

Directors must notify the Secretary of the Corporation in writing not less than fourteen (14) days prior to the date of any shareholder meeting called for the election of directors.

Qualification and Nomination of Directors

The Corporation’s Articles of Incorporation authorize the number of directors to be not less than five (5) and not more than twenty-five (25). Further, the Corporation’s Articles of Incorporation and Bylaws provide for three (3) classes of directors with staggered terms of office of three (3) years that expire at successive annual meetings. Pursuant to Article II, Section 207(b), of the Corporation’s Bylaws, no director or nominee shall stand for election, if as of the date of election, he or she shall have attained the age of seventy-two (72) years old. Currently, the number of directors is set at fourteen (14): Class 1 consists of four (4) directors, Class 2 consists of four (4) directors, and Class 3 consists of six (6) directors.

The Nominating Committee believes that a director nominee must have the following attributes/qualifications before being recommended as a nominee: stock ownership in the Corporation, the willingness to commit time, a commitment to independence, a commitment to the Corporation’s community, financial competence, a good reputation, integrity, good communication skills, and the willingness and ability to speak up for the interests of the Corporation. A director nominee shall also have expertise that strengthens the Board of Directors. When evaluating potential director nominees, the Nominating Committee considers the skills and expertise of the current Board members and seeks director nominees with knowledge, skills and abilities that enhance and complement — rather than duplicate — the experiences and skills already represented on the Board of Directors. Further, the Nominating Committee ensures director nominees complement the Corporation’s strategic vision and direction, a fundamental priority for the Board of Directors. The Nominating Committee follows the same process for evaluating shareholder-recommended nominees for director.

The Nominating Committee does not have a formal policy with respect to diversity; however, the Board and the Nominating Committee believe that it is essential that members of the Board of Directors represent diverse viewpoints and experience. In considering candidates for the Board, the Nominating Committee considers the entirety of each candidate’s credentials in the context of these standards.

Director Nominees

The Board of Directors nominated incumbent directors Alexandra C. Chiaruttini, Eugene J. Draganosky, Todd L. Herring, and James J. Lott to serve as Class 1 Directors until the expiration of the term of the class or until their earlier death, resignation or removal from office.

The proxyholders intend to vote all proxies for the election of each of the nominees named below, unless you indicate that your vote should be withheld from any or all of them.

The Board of Directors proposes the following nominees for election as Class 1 Directors at the annual meeting:

Class 1 Director Nominees

Alexandra C. Chiaruttini
Eugene J. Draganosky
Todd L. Herring
James J. Lott

The Board of Directors recommends that shareholders vote FOR the proposal to elect the nominees listed above.

Director Deferred Fee Plan

In January 2001, ACNB Bank established a director deferred fee plan. Directors Chaney, Elsner, Herring, Kelley, Lott, Newell, and Stock participated in 2024. Directors may defer up to 100% of the director’s income. Benefits are payable upon termination of service, change of control, and by specific participant election in accordance with IRS Code Section 409A. The deferred fees earn interest, and the interest and plan expenses are funded by bank-owned life insurance (BOLI).

Variable Compensation Plan

Effective January 1, 2018, the ACNB Bank Variable Compensation Plan was amended to allow directors to participate under the same terms as employees in order to better align the interests of the directors with the shareholders and to place similar restrictions, as placed upon employees who are granted

TABLE OF CONTENTS

restricted stock, on grants of shares from the 2018 Omnibus Stock Incentive Plan, any successor plan, or any similar plan under which equity awards may be granted and directors are eligible to participate. During 2024, no Variable Compensation Plan awards were granted to non-employee directors.

Director Supplemental Life Insurance Plan

ACNB Bank has a director supplemental life insurance plan. All non-employee directors are eligible for the life insurance benefit, subject to underwriting criteria and purchase of bank owned life insurance (BOLI) by the Bank. The plan currently insures nine (9) directors. The director life insurance benefit of $250,000 per participating director shall be provided unless the director separates from service prior to reaching the retirement age without at least nine (9) years of service, in which case the benefit is $100,000. This life insurance benefit is funded through a single premium BOLI program because BOLI is a more cost-efficient way of providing the benefits. The amount of death benefits is the amount set forth in the individual’s policy endorsement. The eligible participating directors are not required to pay any premiums on the life insurance policy, but have the imputed value of the insurance coverage included in their taxable incomes.

Long-Term Care Insurance

ACNB Bank offers long-term care insurance to directors, and eligibility is subject to medical underwriting acceptance. The plan currently insures eight (8) directors. The eligible participating directors are not required to pay any premiums. The long-term care insurance provides a monthly maximum base benefit of $4,000 for long-term care needs.

TABLE OF CONTENTS

February 1, 2025. The Corporation believes that this acquisition will provide increased scale and an expanded product set to deliver to customers, which should drive long-term growth and profitability in future years, and therefore enhance long-term shareholder value. While the 2024 financial results were comparable to 2023, it should also be noted that the Corporation incurred approximately $2.0 million in merger-related expenses in 2024 as a result of this strategic acquisition. The Corporation believes it is appropriate to consider these expenses incurred in furtherance of the execution of the Corporation’s strategic plan in conjunction with the 2024 financial results.

In addition, the Corporation’s compensation philosophy aims to sustain and enhance long-term investor value, enforce internal controls deemed appropriate by our auditors and regulators, and execute the strategic plans as prioritized by the Board of Directors.

The Compensation Committee and the Board of Directors of the Corporation seek to establish fair compensation policies in order to attract, motivate, reward and retain competent executives whose efforts will enhance the Corporation’s profitability and growth without exposing the Corporation to undue risk. The Compensation Committee treats compensation as an evolving process depending on the strategic objectives of the Corporation, as determined by the Board of Directors at that time.

The Role of the Named Executive Officers in Setting Compensation

The Named Executive Officers do not participate in the determination process of their respective annual base salaries and are not present when their respective compensation is discussed by the Compensation Committee or discussed and approved by the Board of Directors.

Mr. Helt, as President & Chief Executive Officer of the Corporation and ACNB Bank, provides insight to the Compensation Committee on the performance and compensation of ACNB Bank’s executive officers including the other Named Executive Officers. He also assists in establishing performance goals and objectives for these executive officers.

The Compensation Process for the Named Executive Officers

	President & Chief Executive Officer of the Corporation and ACNB Bank			• Discusses the Named Executive Officers’ performance with the Compensation Committee and provides insight on merit compensation.
				• Is not present when his performance and compensation are discussed.
	Compensation Committee			• Reviews the performance of the President & Chief Executive Officer of the Corporation and the Bank in his absence.
				• Reports on the performance of the Named Executive Officers and recommends the compensation levels to the Board of Directors.
	Board of Directors			• Without any Named Executive Officers participating or present, discusses the compensation levels of the Named Executive Officers and determines the levels of compensation.
				• Uses its business judgment and the Compensation Committee’s recommendation in determining compensation.

The Role of a Consultant in Setting Compensation

The Compensation Committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, legal counsel, or other adviser. The Compensation Committee is directly responsible for retaining, determining the independence, determining if a conflict of interest exists, compensating, and overseeing the work of its advisers.

The Compensation Committee engaged the services of Blanchard Consulting Group for projects related to the review of both director and executive compensation, including the Corporation’s incentive plans, the results of which were implemented in 2022. The Compensation Committee engaged Blanchard Consulting Group for services relating to executive and director compensation in 2024; In addition, ACNB Bank management consulted Blanchard Consulting Group on an as needed basis in 2024 with respect to general employee compensation matters. The Compensation Committee also reviewed and considered educational materials from various webinars and conferences, as well as other resources, as further explained in Benchmarking below.

Benchmarking

For 2024, the Compensation Committee reviewed the information provided by Blanchard Consulting Group which included benchmarking data gathered from external salary surveys and was focused on an agreed upon peer group. In 2024, the Compensation Committee reviewed additional external salary survey data and information it received from various webinars, conferences and publications. This information provides general compensation trends and is not used to specifically benchmark any specific element of executive compensation to any specific financial institution or group of financial institutions, but is only used as an educational source as to the current trends in compensation.

Base Salary

Base salaries for our NEOs are recommended annually by the Compensation Committee for approval by the Board and are designed to compensate each executive for the experience, education, responsibilities and other qualifications of the executive that are essential to the specific role the executive serves within the organization. Base salaries are set at levels competitive within the industry and the local market area in order to attract and retain executive officers who possess the knowledge, skills and abilities necessary to successfully execute their duties and responsibilities. The base salaries for each of our NEO’s for the two most recent fiscal years and the year-over-year change are set forth in the table below.

Executive	2023 Base Salary			2024 Base Salary			Year-over- year change (%)
James P. Helt		$	546,000		$	572,645		4.9
Jason H. Weber		$	327,600		$	341,400		4.2
Brett D. Fulk		$	315,000		$	321,300		2.0
Laurie L. Laub		$	312,000		$	325,100		4.2
Douglas A. Seibel		$	298,700		$	310,650		4.0

In determining 2024 base salaries for all NEOs, the Compensation Committee considered the Corporation’s earnings performance in 2023 on measures such as net income and return on average equity (“ROAE”), as well as the labor market and inflationary wage pressures the Bank was experiencing at that time. The Committee also considered factors specific to each NEO, such as individual and departmental performance, compensation history, competitive market positioning and other relevant factors.

Variable Compensation Plan — Overview

The Compensation Committee that short term cash and long term equity incentive bonus awards are an appropriate mechanism to attract, motivate, and aid in the retention of executives, link the long-term compensatory interests of NEOs to the interests of shareholders, and incentivize the achievement of the Corporation’s strategic goals. To provide such incentive bonus awards, effective January 1, 2014, and subsequently amended effective January 1, 2018, January 1, 2021, and March 1, 2022, the Compensation Committee established the ACNB Bank Variable Compensation Plan (the “Plan”), which provides guidelines for awarding cash and/or equity incentive bonuses. Under the Plan, the Compensation Committee may make a recommendation to the Board of Directors to award stock under the ACNB Corporation 2018 Omnibus Stock Incentive Plan, any successor plan, or any similar plan under which equity awards may be granted, if it chooses to make equity awards. The Board of Directors also reserves the right to amend, suspend or terminate the Plan at any time. The guidelines contained in the Plan include general restrictions such as:

•

the award formulas are to be constructed to align the interests of the participant with those of the shareholders;

•

the participant must have an overall rating of “Meets Expectations” on his or her most recent individual performance appraisal, as applicable;

•

no incentive bonuses may be awarded if the Bank’s CAMELS rating assigned by its regulators falls below a certain rating;

•

no incentive bonuses will be awarded if the Board of Directors determines that the dividend payable to the shareholders is not reasonable or competitive; and,

TABLE OF CONTENTS

•

all bonuses are subject to a clawback provision, as well as the Corporation’s Excess Incentive Compensation Recovery Policy Statement.

The Plan is prospective in design with the utilization of a defined payout formula that is based upon the achievement of predefined ACNB Bank and ACNB Corporation financial performance metrics, departmental or individual goals, as well as corporate or strategic goals, as determined by the Board of Directors and/or Compensation Committee, with recommendations by the Bank’s President/CEO and Human Resources Manager. The participants are eligible to receive both variable cash awards and variable equity awards in the form of ACNB Corporation restricted stock. Payouts under the Plan are based on a percentage of the annualized base salary of the participant in the calendar Plan year upon which the award is based. The Plan and each performance period operate on a calendar year basis of January 1 to December 31 for the Plan Year. Thus, variable compensation awards paid in 2024 under the Plan were based on 2023 performance. Upon completion of each fiscal year, the Compensation Committee determines each NEO’s cash and equity incentive awards relative to corporate performance against the pre-established metrics and targets.

2023 Variable Compensation Plan Parameters

The minimum requirements for any participant to receive an award under the Plan in 2024 for the Plan year ending December 31, 2023 were that: (1) the Bank maintains a non-performing assets level below 1.5%; (2) ACNB Corporation achieves a minimum level of annual net income of $22.3 million; and (3) the individual Plan participant achieves a “satisfactory” performance evaluation score. These parameters are considered triggers to activate the 2023 plan for participants, subject to the Board of Directors and/or Compensation Committee’s authority to determine if an extraordinary occurrence has taken place, such that performance goals or minimum requirements should be adjusted.

Beyond such minimum performance triggers to activate the Plan, the Compensation Committee and Board of Directors set threshold, target, and maximum performance levels for ACNB Bank and ACNB Corporation financial performance metrics and strategic goals. In the case of financial metrics, the threshold, target, and maximum levels are determined based on a percentage of the annual ACNB Corporation budget that is approved by the Board of Directors. The variable cash and variable equity award payouts under the Plan are calculated using a ratable approach, in which award payouts are calculated as a proportion of threshold, target and maximum award opportunity levels based upon goal weightings. Performance between threshold and target or between target and maximum would result in interpolated payouts on a straight-line basis. If performance is below threshold for a given performance goal, no incentive would be paid for that goal. Performance above maximum for a given goal would result in payout at maximum for that goal.

The following factors were established as the target levels for the ACNB Bank and ACNB Corporation financial performance metrics and strategic goals for 2023:

The Strategic Initiatives final rating is set on a rating scale of 0-3, with 3 being the maximum rating, by the Board of Directors on recommendation by the Compensation Committee, in its discretion but based on management’s achievement of the initiatives and goals outlined in the Strategic Plan approved by the Board of Directors.

One-Time Adjustments

Under the terms of the Plan, the Compensation Committee has the authority to adjust financial performance metrics used to determine Plan awards for one-time positive or negative events outside of the Corporation’s normal operations which have a material effect on the Corporation’s results. Potential adjustments include but are not limited to tax-related matters, merger-related costs, gains or losses arising from security sales, changes in regulation, and other significant events.

The Corporation’s GAAP net income and ROAE for the year ended December 31, 2023 were $31.68 million and 12.23%, respectively. These results were negatively affected by an after-tax securities loss of $3,479,192, incurred as a result of the Corporation’s intentional decision to direct management to participate in a securities restructuring of the Corporation’s investment portfolio in December 2023, as disclosed in a Form 8-K filed with the SEC on December 15, 2023. Because the Compensation Committee expects that the securities repositioning and higher yielding assets purchased with the proceeds of the lower yielding sold assets will result in long-term profitability in for the Corporation and therefore enhance long-term shareholder value, the Compensation Committee determined that it was appropriate to exclude this loss from the 2023 performance results, and to apply the Corporation’s adjusted performance results to its performance metrics when determining awards under the Plan. It is the Compensation Committee’s intention to also exclude the estimated income from the securities repositioning from calendar year 2024 results under the Plan. Excluding the impact of the $3,479,192 in after tax expense, Net Income and ROAE were $35.16 million and 13.57%, respectively, for the year ended December 31, 2023. These adjusted figures are sometimes referred to in this proxy statement as Adjusted Net Income and Adjusted ROAE, respectively.

2024 Cash Awards paid under the Plan for 2023 Performance

With respect to the variable cash awards payable to the Named Executive Officers in 2024 for 2023 performance, Mr. Helt’s maximum variable cash award was sixty-five (65%) of his 2023 salary, and the maximum variable cash award for all other NEOs was forty-five (45%) of his or her 2023 salary. For Mr. Helt, the factors and corresponding weight in determining the amount of the cash award were: Net Income, 63%; Loan Growth, 27%; and Individual/Departmental Goal, 10%. For all other NEOs, the factors and corresponding weight in determining the amount of the cash award were: Adjusted Net Income, 52.5%; Loan Growth, 22.5%; and Individual/Departmental Goals, 25%.

TABLE OF CONTENTS

2024 Equity Awards paid under the Plan for 2023 Performance

With respect to the variable equity awards payable to the Named Executive Officers in 2024 for 2023 performance, in the form of a restricted stock equity award under the ACNB Corporation 2018 Omnibus Stock Incentive Plan, Mr. Helt’s maximum variable equity award was sixty-five (65%) of his 2023 salary, and Mr. Seibel and Ms. Laub’s maximum variable equity award was forty-five (45%) of his or her 2023 salary. For all NEOs, the factors and corresponding weight in determining the amount of the equity award were: Adjusted ROAE, 50%; and Execution on Strategic Initiatives, 50%.

The restricted shares awarded to the Named Executive Officers vest in one-third (1∕3) tranches, with the first third vesting immediately upon award in 2024, the next third vesting on January 1, 2025, and the last third vesting on January 1, 2026. The dollar value of the equity award is converted to shares of common stock based on the same price for reinvestment of shares in connection with the Corporation’s Dividend Reinvestment Plan for the first quarter of 2024. The Compensation Committee intends to consider restricted stock through the ACNB Corporation 2018 Omnibus Stock Incentive Plan or another successor plan in the future in conjunction with the ACNB Bank Variable Compensation Plan with the intended purpose to encourage stability and longevity in executive management.

Employment Agreements

We provide NEOs with employment agreements including change in control provisions as a market expectation in talent management and to encourage executives to focus on generating shareholder value during any potential change in control. For further explanation regarding the details of the employment agreements that apply to NEOs, see the Employment Agreements heading in the Executive Compensation section.

Deferred Compensation Plans

The Corporation offers deferred compensation plans for the purpose of attracting and retaining qualified executives and to provide NEOs an economic incentive for long-term service to the Corporation. These include unfunded non-qualified deferred compensation plans characterized as either supplemental executive retirement plans (SERPs) or salary continuation agreements. For further explanation regarding these agreements, see the Supplemental Executive Retirement Plans and Deferred Compensation Agreement headings in the Executive Compensation section.

Other Benefits

The Corporation provides certain other benefits to some or all of the NEOs that are appropriately limited in scope and value and are either offered to the Corporation’s employee base at large or commonly expected to be provided to senior executives. This would include benefits like health, dental, vision and other insurance benefits, 401(k) and pension plan benefits , group life insurance and disability plans, supplemental life and long term care plans, vehicle stipends or memberships, and other similar benefits. For more information regarding these benefits, see the Supplemental Life Insurance Plan, Group Term Life Insurance Plan, Long-Term Care Insurance, 401(k) Plan, and Defined Benefit Plan sections of the Executive Compensation section.

Policies and Practices Related to the Timing of Option Awards

While the Corporation does not have a formal written policy in place with regard to the timing of awards of options in relation to the disclosure of material nonpublic information, the Compensation Committee does not seek to time equity grants to take advantage of information, either positive or negative, about the Corporation that has not been publicly disclosed. It has been the Corporation’s recent practice to grant most of its equity awards in the form of restricted stock.

Say on Pay and Shareholder Engagement

The Corporation is required to provide a non-binding shareholder advisory vote on the compensation of the NEOs. The Corporation conducts this advisory vote on an annual basis. At the 2024 annual meeting

TABLE OF CONTENTS

of shareholders, the holders of 4,061,573 shares of Common Stock, or 89.15% of the 4,555,882 shares voting on the proposal, voted to approve the non-binding, advisory proposal on the compensation of the Corporation’s executive officers.

The Compensation Committee believes the results of this vote demonstrate significant support for the Corporation’s executive compensation policies and practices among shareholders. Though the Say-on-Pay vote is nonbinding, the Board of Directors and the Compensation Committee seriously consider the opinions of, and feedback from, our shareholders when making compensation decisions. The Compensation Committee expects to continue to adhere to the compensation policies, principles and programs described herein in future years, and will continue to consider these non-binding advisory results on our compensation programs, among other factors.

Mitigation in Plan Design Risk

The Compensation Committee considers, in establishing and reviewing the executive compensation program and in determining annual performance goals, whether the program encourages any unnecessary or excessive risk taking and concludes:

•

the Corporation’s executive compensation plans do not encourage executives to take unnecessary and excessive risks that could threaten the value of the Corporation;

•

The executive compensation plans are structured so that their potential for generating unacceptable risk that could materially affect the value of the Corporation is limited; and

•

The compensation plans are not structured to create substantial opportunities to benefit due to material manipulation of financial results.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the “Compensation Discussion and Analysis” section of this document for the year ended December 31, 2024 with the Corporation’s management.

Based on the Committee’s review and discussions noted above, the Compensation Committee recommended to the Board that the Corporation’s Compensation Discussion and Analysis be included in this Proxy Statement and incorporated by reference in the Corporation’s Annual Report of Form 10-K for the fiscal year ended December 31, 2024.

Employment Agreements

The Corporation and/or ACNB Bank has entered into employment agreements with each of the Named Executive Officers. Under the employment agreements, the Named Executive Officers are eligible for bonuses, paid time off, participation in employee benefit plans, and reimbursement of business expenses. The initial terms of each employment agreement is three (3) years which automatically extend for an additional one (1) year period on each annual anniversary date of the employment agreement, unless notice is given one hundred eighty (180) days prior to the anniversary date, so that on each anniversary date, if notice had not been previously given, the term shall continue for three (3) years.

Each employment agreement automatically terminates if the executive is terminated for “Cause”, as defined in each employment agreement, or if the executive voluntarily terminates employment and all rights under the employment agreement will terminate except for the arbitration clause.

Each employment agreement automatically terminates if the executive terminates their employment for “Good Reason”, as defined in each employment agreement. Under the employment agreements for Messrs. Helt and Seibel and Ms. Laub, if the employment agreement is terminated for “Good Reason”, then the executive would receive 2.99 times the executive’s agreed compensation and benefits for two (2) years. Under the employment agreement for Mr. Weber, if the employment agreement is terminated for “Good Reason”, then the executive would receive 2.0 times the executive’s agreed compensation and benefits for two (2) years. Under the employment agreement for Mr. Fulk, if the employment agreement is terminated for “Good Reason”, then the executive would receive his remaining base salary not to exceed 2.99 times or be less than least 2.0 times the executive’s agreed compensation and benefits for two (2) years.

TABLE OF CONTENTS

Each employment agreement automatically terminates upon the executive’s disability, as defined in each employment agreement, and the executive will receive employee benefits and 75% of their compensation until (a) they return to work, (b) reach age sixty-five (65), (c) die, or (d) the employment period under the agreement ends.

If the executive’s employment is terminated either involuntarily or voluntary, under certain circumstances as set forth in each employment agreement, following a “Change in Control”, as defined in each employment agreement, each executive is entitled to a lump sum payment and continued benefits for two (2) years. Under the employment agreements for Messrs. Helt and Seibel and Ms. Laub, each executive would receive 2.99 times the executive’s agreed compensation. Under the employment agreement for Mr. Weber, he would receive 2.0 times his agreed compensation. Under the employment agreement for Mr. Fulk, he would receive his remaining base salary not to exceed 2.99 times or be less than least 2.0 times the executive’s agreed compensation and benefits for two (2) years. Messrs. Helt, Weber and Seibel and Ms. Laub would receive limited grossed-up payments, if necessary.

Each employment agreement contains restrictive covenants precluding the executives from engaging in competitive activities in a certain area and provisions preventing the Executives from disclosing proprietary information about the Corporation and ACNB Bank.

Equity Compensation

In 2018, the Corporation’s shareholders approved the ACNB Corporation 2018 Omnibus Stock Incentive Plan, which allows the Corporation to grant up to 400,000 restricted shares of ACNB Corporation common stock under the plan. Awards that may be granted under the 2018 Omnibus Stock Incentive Plan include stock options (including qualified stock options and non-qualified stock options), stock appreciation rights (“SARs”), stock awards, restricted stock, stock units and restricted stock units (“RSUs”), performance awards, and director compensation. All awards and the terms and conditions of such awards will be set forth in a written agreement.

On March 15, 2024, based on the results of the Variable Compensation Plan described in the Compensation Discussion and Analysis—2024 Equity Award for 2023 performance, the Corporation granted a total of 22,721.655328 restricted shares to the Named Executive Officers employed by ACNB Bank.

Supplemental Life Insurance Plans

In January 2001, ACNB Bank implemented a supplemental life insurance plan for certain officers, including certain of the Named Executive Officers, of the Bank to provide death benefits for each officer’s designated beneficiaries, which was amended and restated in December 2014 and amended on November 2023 (“2014 Life Insurance Plan”). Beneficiaries designated by an officer are entitled to a split-dollar share of the death proceeds from the life insurance policies on each officer equal to the lesser of two (2) times the officer’s base annual salary or the maximum dollar amount of the participant’s interest in the policy based upon the vesting schedule attached to his or her split-dollar policy endorsement. The plan is unsecured and unfunded, and there are no plan assets. The Bank has purchased single premium bank-owned life insurance (BOLI) policies on the lives of the officers and intends to use income from the BOLI policies to offset the plan benefit expenses. The NEOs with benefits under the 2014 Life Insurance Plan are Mr. Helt, Ms. Laub, and Mr. Seibel.

Effective November 1, 2023, the Bank implemented the 2023 Executive Supplemental Life Insurance Plan (“2023 Life Insurance Plan”). The 2023 Life Insurance Plan is generally comparable to the 2014 Life Insurance Plan, with split-dollar share of the death proceeds from the life insurance policies on each officer equal to the lesser of two (2) times the officer’s base annual salary or the maximum dollar amount of the participant’s interest in the policy based upon the vesting schedule attached to his or her split-dollar policy endorsement; however, subject to acceleration of vesting due to certain events, benefits under the 2023 Life Insurance Plan vest over a period of five (5) years. The NEO with benefits under the 2023 Life Insurance Plan is Mr. Weber.

Group Term Life Insurance Plan

ACNB Bank maintains a group term life insurance plan. All full-time Bank employees are eligible to participate in the plan. For 2024, the insurance benefit for employees was calculated as two (2) times base salary, with a maximum of $250,000.

Long-Term Care Insurance

ACNB Bank provides long-term care insurance to certain officers including the Named Executive Officers. The insurance provides a monthly benefit for long-term care needs.

TABLE OF CONTENTS

401(k) Plan

ACNB Bank maintains a defined contribution profit-sharing 401(k) plan. ACNB Bank is the plan sponsor and plan administrator. The plan is subject to certain laws and regulations under the Internal Revenue Code, and participants are entitled to certain rights and protection under the Employee Retirement Income Security Act of 1974.

An employee is eligible to participate in the plan after working for six (6) months and attaining the age of twenty (20) years and six (6) months. An eligible employee is automatically enrolled in the 401(k) plan, and the Bank will automatically withhold 6% of the employee’s wages unless otherwise directed. ACNB Bank matches a percentage of the employee’s contribution. In 2024, ACNB Bank’s contribution equaled 100% of the employee’s contribution up to 3% of earned compensation plus 50% of the next 2% of earned compensation. ACNB Bank adopted a “safe harbor” provision for its 401(k) plan, which vests eligible contributions immediately upon entering the plan for both employer and employee contributions.

Defined Benefit Plan

Employees of ACNB Bank hired on or before March 31, 2012, are covered under the Bank’s Group Pension Plan for Employees provided that they meet the eligibility criteria of the plan. The plan is a defined benefit pension plan under the Employee Retirement Income Security Act of 1974. The plan was restated November 1, 1998, effective January 1, 1999, and subsequently amended effective November 1, 2000, January 1, 2010, and April 1, 2012. ACNB Bank is the plan sponsor and plan administrator.

Amounts are set aside each year to fund the plan on the basis of actuarial calculations. The amount of contribution to a defined benefit pension plan on behalf of a specific employee cannot be separately or individually calculated. ACNB Bank made no contributions to the plan in 2024, as the plan is considered to be well funded.

Each employee of ACNB Bank hired on or before March 31, 2012, who attained the age of twenty (20) years and six (6) months and who completed one (1) year of service, in which one thousand (1,000) hours were worked, was eligible to participate in the plan on the following anniversary of the plan. The plan generally provides for a prospective benefit at the age of sixty-five (65) years for the employee’s remaining lifetime with payments certain for five (5) years. Effective January 1, 2010, the formula for determining a participant’s benefit is the participant’s earned benefit as of December 31, 2009, plus 0.75% of the participant’s average monthly pay multiplied by the participant’s benefit service earned on and after January 1, 2010, but not more than twenty-five (25) years. If an employee has completed thirty (30) or more years of vested service, he or she is eligible to retire at age sixty-two (62) with no reduction applied to his or her benefit.

Messrs. Weber and Fulk were hired after March 31, 2012, and therefore, they are not eligible to participate in the Group Pension Plan.

Supplemental Executive Retirement Plan

ACNB Bank entered into retirement income agreements with the Named Executive Officers to provide supplemental retirement income benefits to these officers upon the later of reaching their normal retirement date or separation of service. Under the agreement for Messrs. Helt, Weber and Fulk and Ms. Laub,

TABLE OF CONTENTS

benefits are payable in equal monthly installments for the greater of one hundred-eighty (180) months or the executive’s life. Benefits are also payable upon death. Benefit amounts will be determined by the individual’s number of years of service. Benefits accrue annually, but may be reduced if termination of service occurs before the normal retirement date except after a change in control. In exchange for providing benefits under the agreements, the executives are bound by respective noncompetition arrangements. No benefits are payable under the agreements if the executive directly or indirectly engages in a business or activity that may be deemed competitive with ACNB Bank or the Corporation within fifty (50) miles of ACNB Bank’s principal office. If the termination occurs before the executive’s respective retirement date, this restriction applies for five (5) years after the date of the executive’s separation of service; however, the restriction will not extend longer than three (3) years after the executive begins to receive benefits under the respective agreement. If the separation occurs after the executive’s retirement date, then the restriction shall be in place for three (3) years. The restriction does not apply after a change in control. Under the terms of Mr. Seibel’s agreements, the Bank shall credit $100,000 per calendar year to executive’s account as long as executive is employed by the Bank at the time such amount is credited. In the event Mr. Seibel’s employment is terminated for cause no benefits of any kind will be due or payable under the terms of his agreements and all rights shall be forfeited. In the event Mr. Seibel separates from service, including death but excluding for cause, he (or his beneficiary) shall be paid his vested account balance in monthly installments for thirty-six (36) months. In the event of a change in control, Mr. Seibel will be paid his vested account balance in a lump sum. ACNB Bank purchased bank-owned life insurance policies on each officer to fund the retirement income agreements.

Deferred Compensation Agreement

ACNB Bank entered into a deferred compensation agreement with Brett D. Fulk. The purpose of the deferred compensation agreement is to provide Mr. Fulk with retirement benefits and tax-planning opportunities. All NEOs were offered the opportunity to participate in this deferred compensation arrangement, with Mr. Fulk the only NEO electing to enter into the deferred compensation agreement.

Under the deferred compensation agreement, Mr. Fulk may annually elect to defer the payment of a portion of his base salary and/or bonus by filing a deferral election form with the plan administrator, setting forth the amount of the deferral and its duration. Benefits under the deferred compensation agreement will be paid to Mr. Fulk upon termination of employment after “normal retirement age,” upon “early termination,” or upon a “disability” (as each terms are defined in the agreement) prior to normal retirement age. Benefits will be distributed in 180 monthly installments if termination of employment occurs after normal retirement age or 120 monthly installments upon the occurrence of an early termination or disability, with the payment commencing in the month following the payment event. In the event a “change in control” (as defined in the agreement) followed within twenty-four (24) months by a termination of employment prior to the executive’s normal retirement age, the executive’s deferral account will be paid in a lump sum within thirty (30) days following the date of termination of employment. In addition to any deferrals, ACNB Bank may contribute to Mr. Fulk’s deferral account. During 2024, ACNB Bank did not contribute to Mr. Fulk’s deferral account. Mr. Fulk’s deferral account will be credited with interest at a rate equal to the crediting rate (as defined in the agreement).

CEO Pay Ratio

As required by applicable SEC rules, we are providing the following information:

We completed the following steps to identify the median employee and to determine the annual total compensation of our median employee and CEO:

TABLE OF CONTENTS

We identified our employee population as of December 31, 2024, including all full-time, part-time, temporary, and seasonal employees employed on that date. This date was selected because it aligned with our calendar year- end and allowed us to identify employees in a reasonably efficient manner.

To find the median employee (other than our CEO), we used medicare wages from our payroll records as reported to the Internal Revenue Service on Form W-2 for 2024. In making this determination, we annualized compensation for employees who were employed on December 31, 2024 but did not work for us the entire year. No full-time equivalent adjustments were made for part-time employees.

We identified our median employee using this compensation measure and methodology, which was consistently applied to all our employees included in the calculation.

After identifying the median employee, we added together all of the elements of such employee’s compensation for 2024 in accordance with SEC requirements, resulting in annual total compensation of $61,268.

As reported in the Total column of our 2024 Summary Compensation Table, the annual total compensation for 2024 of James P. Helt, our President and CEO, was $1,615,962.

Based on this information, the ratio for 2024 of the annual total compensation of our Chairman, President & Chief Executive Officer to the annual total compensation of our median employee is 26.38 to 1.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

As discussed above, the Named Executive Officers, have entered into certain agreements with the Corporation and/or ACNB Bank, which govern any payments upon termination or change in control. The agreements are described under the caption “Executive Compensation—Employment Agreements, Supplemental Life Insurance, Employment, Change in Control, and Supplemental Executive Retirement Plan Agreements” included in the Compensation Discussion and Analysis. Upon any termination of employment, the respective Named Executive Officer will be entitled to receive normal retirement benefits equal to an amount determined by an actuarial formula as described in the defined benefit plan. We calculated the potential post-employment payments due to each of the Named Executive Officers assuming each executive terminated employment or a change in control occurred on December 31, 2024. Actual amounts payable can only be determined at the time of such executive’s termination.

Column (h). Reflects “Net Income” reported in the Corporation’s Consolidated Statements of Income for each year.

Column (i). The Corporation has identified Return on Average Equity as the company-selected measure for the pay versus performance disclosure, as it represents the most important financial performance measure used to link compensation actually paid to the PEO and the Other NEOs in 2024 to the Corporation’s performance. This performance measure may not have been the most important financial performance measure for prior years, and we may determine a different financial performance measure to be the most important financial performance measure in future years.

These measures listed are not ranked. As discussed in the Compensation Discussion and Analysis, the Compensation Committee does consider the occurrence of unusual, extraordinary, or strategic events in determining Compensation Actually Paid, and therefore these measures may be adjusted for these purposes.

Transactions with Directors and Executive Officers

Some of ACNB Corporation’s directors, executive officers, and their immediate family members and the companies with which they are associated were customers of and had banking transactions with ACNB Corporation’s subsidiary bank during 2024. All loans and loan commitments made to them and to their companies were made in the ordinary course of ACNB Bank business, on substantially the same terms, including interest rates, collateral and repayment terms, as those prevailing at the time for comparable transactions with other customers of the Bank, and did not involve more than a normal risk of collectability or present other unfavorable features. ACNB Corporation’s subsidiary bank anticipates that similar transactions will be entered into in the future.

The Corporation does not regularly engage in business transactions with directors and executive officers outside of its business of banking. Generally, any other significant transactions with directors or executive officers are reviewed and approved by the Board of Directors on a case-by-case basis as the need arises. ACNB Bank’s Expenditure and Procurement Policy requires prior approval by the Board of Directors of all non-banking and lending related party transactions over $50,000. All related party transactions of which the Corporation becomes aware, outside of those banking and lending transactions made in the ordinary course of business, are reported to the Audit Committee on a quarterly basis regardless of dollar amount.

In connection with the acquisition of Traditions Bancorp, Inc., effective February 1, 2025, the Corporation and ACNB Bank entered into a Separation and Non-competition Agreement with Mr. Draganosky relating to the termination of his employment as Chief Executive Officer of Traditions Bancorp, Inc. and Traditions Bank and his related employment agreement with Traditions Bancorp, Inc. and Traditions Bank. Under the terms of the agreement, Mr. Draganosky received a lump sum separation payment of $1,373,500 and maintenance of at least $800,000 in split dollar bank owned life insurance for at least 3 years following the effective date. In exchange, Mr. Draganosky agreed such payment satisfies all obligations under his employment agreement and that he will be subject to certain non-competition and non-solicitation restrictions for a period of 18 months as delineated in the agreement.

In connection with the acquisition of Traditions Bancorp, Inc. on February 1, 2025, an employment agreement by and between ACNB Bank and Christopher Helt went effective for Mr. Helt to serve as Senior Vice President/Regional Commercial Lending Manager for the York Region of ACNB Bank. Christopher Helt is the brother of CEO James P. Helt. Christopher Helt has served in a variety of commercial lending and business services leadership roles for Traditions Bank, the banking subsidiary of Traditions Bancorp, Inc., since 2007, and was most recently a Senior Commercial Relationship Manager for Traditions Bank prior to the acquisition. The term of the employment agreement is three years and six months. Mr. Helt will receive an annual base salary of $180,000, subject to customary withholdings and taxes, which may be increased from time to time. In addition, as consideration for executing the employment agreement, which contains certain restrictive covenants, Mr. Helt received a sign on bonus of $25,000 on February 1, 2025, and he will receive additional bonuses of $25,000 payable on February 1, 2026, and February 1, 2027. Further, Mr. Helt is entitled to be considered for bonuses each year, as determined in the Bank’s sole discretion, paid time off, participation in employee benefit plans, and reimbursement of reasonable out-of-pocket business expenses. The Bank intends for any bonuses awarded to be based on its Regional Commercial Lending Manager incentive program which is applied equally to similarly situated employees of ACNB Bank. If his employment is terminated under certain circumstances as set forth in the employment agreement, Mr. Helt is entitled to a payment of 1.0 times his compensation and continued benefits for twelve months. Both during and upon termination of the employment agreement, Mr. Helt is subject to certain customary confidentiality, non-solicitation, and non-competition provisions and restrictions.

AUDIT COMMITTEE REPORT

The Audit Committee of the Board of Directors is comprised of directors who meet SEC and Nasdaq standards for independence. The Audit Committee operates under a written charter adopted by the Board of Directors in April 2000, which has been subsequently revised and is incorporated by reference from the Governance Documents section of the ACNB Corporation Investor Relations website at investor.acnb.com.

TABLE OF CONTENTS

The Audit Committee met with management periodically during the year to consider the adequacy of ACNB Corporation’s internal controls and the objectivity of its financial reporting. The Audit Committee discussed these matters with ACNB Corporation’s independent registered public accounting firm and with appropriate ACNB Corporation financial personnel and internal auditors. The Audit Committee also discussed with ACNB Corporation’s management and independent registered public accounting firm the process used for certifications by ACNB Corporation’s Chief Executive Officer and Chief Financial Officer, which are required for certain of ACNB Corporation’s filings with the SEC.

The Audit Committee also met privately at its regular meetings with both the independent registered public accounting firm and the internal auditors, each of whom has unrestricted access to the Audit Committee.

The Audit Committee selected Crowe LLP as the independent registered public accounting firm for ACNB Corporation after reviewing the firm’s performance and independence from management.

Management has primary responsibility for ACNB Corporation’s financial statements and the overall reporting process, including ACNB Corporation’s system of internal controls.

The independent registered public accounting firm audited the annual financial statements prepared by management, expressed an opinion as to whether those financial statements fairly present the financial position, results of operations, and cash flows of ACNB Corporation in conformity with generally accepted accounting principles, and discussed with the Audit Committee any issues the firm believes should be raised with the Audit Committee.

The Audit Committee reviewed with management and Crowe LLP, ACNB Corporation’s independent registered public accounting firm, ACNB Corporation’s audited financial statements, as well as reviewed those financial statements and reports prior to issuance. Management has represented, and Crowe LLP has confirmed, to the Audit Committee that the financial statements were prepared in accordance with generally accepted accounting principles.

The Audit Committee received from and discussed with Crowe LLP the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s Communications with Audit Committees and discussed with Crowe LLP its independence. These items relate to that firm’s independence from ACNB Corporation. The Audit Committee also discussed with Crowe LLP matters required to be discussed by applicable requirements of the Public Company Accounting Oversight Board and the SEC. The Audit Committee implemented a procedure to monitor auditor independence, reviewed audit and non-audit services performed by Crowe LLP, and discussed with the firm its independence.

The Audit Committee reviewed the audited financial statements and, based upon the review and discussions above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2024, which is then filed with the SEC.

At present, ACNB Corporation has two individuals designated as “audit committee financial expert”. The Board of Directors has determined that Kimberly S. Chaney and Daniel W. Potts are qualified to serve as ACNB Corporation’s audit committee financial experts and are independent as defined under applicable SEC and Nasdaq rules.

Audit-Related Fees include fees billed for professional services in connection with review of registration statements on Form S-3 and Form S-4 and consulting services.

These services may include audit services, audit-related services, tax services, and other services. Preapproval will generally be provided for up to one (1) year, and any preapproval is detailed as to the particular service or category of services and is subject to a specific budget. In addition, the Audit Committee may also preapprove particular services on a case-by-case basis. None of the services related to any Audit-Related Fees, Tax Fees or All Other Fees described above were approved by the Audit Committee pursuant to the preapproval waiver provisions set forth in the applicable SEC rules. In addition, the Audit Committee annually considers and recommends to the Board of Directors the selection of the Corporation’s independent registered public accounting firm as independent auditors.

DELINQUENT SECTION 16(a) REPORTS

Section 16(a) of the Securities Exchange Act of 1934 requires ACNB Corporation’s directors, executive officers, and shareholders who beneficially own more than 10% of ACNB Corporation’s outstanding equity stock to file initial reports of beneficial ownership and reports of changes in beneficial ownership of common stock and other equity securities of ACNB Corporation with the SEC. Based on a review of copies of the reports filed, and on the statements of the reporting persons, we believe that all Section 16(a) filing requirements were complied with in a timely manner during 2024.

PROPOSALS

Cumulative voting rights do not exist with respect to the election of directors. The four (4) nominees for Class 1 Directors receiving the highest number of “FOR” votes cast, in person or by proxy, by those shareholders entitled to vote will be elected directors of the Corporation.

For the election of directors in Proposal 1, you may vote “FOR” all of the nominees, or your vote may be “WITHHELD” with respect to one (1) or more of the nominees. For the other proposals, you may vote “FOR”, “AGAINST” or “ABSTAIN”. If you “ABSTAIN”, it has the same effect as a vote “AGAINST”. If you sign your proxy card or broker voting instruction card, or vote via internet or telephone, with no further instructions, your shares will be voted in accordance with the recommendations of the Board (“FOR” all of the Board’s nominees, in favor of the non-binding shareholder vote on executive compensation, and “FOR” all other proposals described in this proxy statement).

TO ELECT FOUR (4) CLASS 1 DIRECTORS TO SERVE FOR TERMS OF THREE (3) YEARS AND UNTIL THEIR SUCCESSORS ARE ELECTED AND QUALIFIED.

Nominees for Class 1 Directors are:

Alexandra C. Chiaruttini
Eugene J. Draganosky
Todd L. Herring
James J. Lott

The Board of Directors recommends a vote FOR the election of these nominees.

TO CONDUCT A NON-BINDING VOTE ON EXECUTIVE COMPENSATION.

In accordance with the requirements of Section 14A of the Securities Exchange Act of 1934, as amended (which was added by the Dodd-Frank Wall Street Reform and Consumer Protection Act) and the related rules of the SEC, we are including in these proxy materials a separate resolution subject to shareholder vote to approve, in a non-binding vote, the compensation of our Named Executive Officers.

The shareholders approved a resolution at the Corporation’s 2023 Annual Meeting of Shareholders to conduct an annual advisory vote on the Corporation’s executive compensation for the Named Executive Officers.

As described in detail in this proxy statement, our executive compensation programs are designed to attract, motivate, reward and retain our Named Executive Officers, who are critical to our success. We are asking our shareholders to indicate their support for our Named Executive Officer compensation as described in this proxy statement. This proposal, commonly known as a “Say on Pay” proposal, gives our shareholders the opportunity to express their views on our Named Executive Officer compensation. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our Named Executive Officers and the philosophy, policies and practices described in this proxy statement. Accordingly, we ask our shareholders to vote “FOR” the following resolution at the Annual Meeting of Shareholders:

RESOLVED, that the Corporation’s shareholders approve, on a non-binding basis, the compensation paid to the Named Executive Officers, as disclosed in the Corporation’s Proxy Statement for the 2025 Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the SEC, the compensation tables, the narrative discussion, and the other related tables and disclosure.

The Say on Pay vote is advisory, and therefore not binding on the Corporation, the Compensation Committee, or the Board of Directors. Our Board of Directors and our Compensation Committee value the opinions of our shareholders and, to the extent there is any significant vote against the Named Executive Officer compensation as disclosed in this proxy statement, we will consider our shareholders’ concerns and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

The Board of Directors recommends a vote FOR this proposal.

The Board of Directors has approved the selection of Crowe LLP as the independent registered public accounting firm for the examination of its financial statements for the fiscal year ending December 31, 2025.
