Qualifications and Nomination of Directors

The Corporation's Bylaws authorize the number of directors to be not less than five (5) nor more than twenty-five (25). The Bylaws also provide for three classes of directors with staggered three-year terms of office. Terms of the members of each Class expire at successive annual meetings. Currently, Class A consists of five directors; Class B consists of three directors; and Class C consists of six directors.

The Board nominated the five persons named below to serve as directors until the 2029 Annual Meeting of Shareholders and until their successors are duly elected and qualified or until their earlier death, resignation, retirement or removal from office. The Board Chair individually met with and interviewed each of the candidates for re-nomination toassess if the candidate desired to serve an additional term and to determine the best manner in which each director could serve most effectively in the next three years. The nominees are presently members of the Board and have consented to serve another term as a director if re-elected. Ifthe nominees should be unavailable to serve for any reason, a majority of the Board then in office may select someone to fill the vacancy until the expiration of the term of the Class of directors to which he or she is appointed.

The proxy holders intend to vote proxies for the election of each of the five nominees named below, unless you indicate that your vote should be withheld from any or all of them. Brokers holding shares beneficially owned by their clients do not have the ability to cast votes with respect to the election of directors unless they have received instructions from the beneficial owner of the shares. It is therefore important that you provide instructions to your broker if your shares are held by a broker so that your vote with respect to directors is counted.

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

Thomas R. Brugger

Brian A. Hudson, Sr.

Albert J. Evans

John E. Noone

Joel L. Frank

The Board unanimously recommends a vote FOR the election of each of the nominees listed above as Class A Directors of Mid Penn Bancorp, Inc.

Compensation of the Board

The Corporation periodically obtains or conducts a survey of director fees, committee fees and other director compensation of banks that are similar in asset size and in similar markets to the Corporation and the Bank. The Compensation Committee reviews these surveys and recommends to the full Board any changes to the compensation of Board members for the upcoming year. The Board has final approval of the compensation of its directors. Directors, with the exception of the Lead Independent Director, received an annual Board fee of $65,000 for the year 2025. Mr. Noone received $97,500 for serving as Lead Independent Director and Committee Chair. Committee Chairs received an additional $7,500 in annual compensation. Committee Vice Chairs received an additional $2,500 in annual compensation. Board members who served for a partial year as Committee Vice Chair were paid for the time they served in those positions. Mr. Ritrievi and Mr. Stephon do not receive a fee for serving on the Board.

On April 1, 2025, each non-employee Directorwho was serving on the Board at that time was awarded a restricted stock grant of $50,025, equating to 1,945 shares of the Corporation's common stock, with a fair market value of $25.72 per share, as part of his or her compensation. These common stock awards were granted with a one-year vestingrestriction.

The Corporation and Bank maintain a deferred fee plan for directors, which enables a director to annually elect to defer payment of his or her fees until he or she terminates service on the Board. For 2025, the maximum amount each director could defer was 100% of his or her annual director's fee. Participating directors may elect to receive either a lump sum or equal monthly installments in an amount equal to his or her deferral account (plus interest) upon retirement, early termination, disability, change in control or a hardship. If a director dies before distribution of his or her deferral account commences, the director's designated beneficiary is entitled to receive the amounts in his or her deferral account or the projected account balance at the time the Corporation adopted the deferred fee plan (limited by the amount of net coverage purchased by the Bank), whichever is greater. For 2025, current members of the Corporation's Board participated in this plan as follows: Mr. Kiefer deferred $66,250; Mr. Mowery deferred $66,250; and Mr. Noone deferred $58,500.

As detailed in the "Director Compensation Table," in 2025, the non-employee membersof the Corporation's Board were paid $1,466,525, in the aggregate, for their service as directors, which includes the value of restricted stock awards.

GOVERNANCE OF THE CORPORATION

Overview

The Board believes that the purpose of corporate governance is to ensure that the Corporation employs a system of operating practices and procedures designed to maximize shareholder value in a manner consistent with legal and regulatory requirements and the highest standards of integrity. The Board has adopted and adheres to corporate governance practices which the Board believes promote these objectives, are sound and represent best practices. These governance practices, Pennsylvania law (the state of incorporation), the rules and listing standards of The Nasdaq Stock Market LLC ("Nasdaq") and the Securities and Exchange Commission (the "SEC") regulations, as well as best practices suggested by recognized governance authorities, are continually reviewed for consistency and applicability.

As a result of this review process, in 2023 the Board recommended, and the Corporation's shareholders approved, an amendment to the Corporation's articles of incorporation to eliminate the supermajority shareholder vote requirement in transactions that receive the support of at least eighty percent (80%) of the members of the Board. Going forward, transactions that receive the overwhelming support of the Board will require only such vote of the shareholders, if any, as required by the Pennsylvania Business Corporation Law or Nasdaq rules. In those limited instances in which a vote is required, a majority of votes cast at the meeting will be sufficient to approve the transaction.

With respect to the composition of its Board, the Corporation seeks director candidates who uphold the highest standards of professionalism, are committed to the Corporation's values and are strong independent stewards of the long-term interests of shareholders, employees, customers and the communities in which we work. The Board, through the Nominating and Corporate Governance Committee, considers Board composition on an ongoing basis, with a focus on recruiting directors who exhibit the qualities required to effectively oversee the Corporation, including its present and future strategies. The Board primarily seeks directors with experience in fields relevant to the Corporation's businesses and operations and who are willing to effectively challenge and provide independent oversight of management. The Board seeks candidates who collectively reflect a meaningful level of diversity in four specific areas: expertise and experience; tenure and age; gender, race, ethnicity; and geography.

All of our directors must be qualified in terms of education, professional experience and applicable skills or core competencies. Each director must exhibit integrity, self-assurance, sound judgment, financial literacy, a history of achievement, a collaborative approach to decision making, inquisitiveness, enthusiasm and, of extreme importance, an independent mindset.

The Board believes that it is important that a director's and shareholders' interests are financially aligned. In order to promote such alignment of interests, the Corporation adopted a policy in 2023 that directors seeking re-electionare required to beneficially own, as of the month-endprior to the date of nomination, such number of shares of common stock having an aggregate value of not less than that identified in the table below. The minimum value shall be determined by multiplying the number of shares owned times the greater of the tangible book value per share and stock price. The number of shares, stock price, and tangible book value shall be determined as of the month-endprior to the date of nomination.

The Board also believes that director refreshment is an important component of good corporate governance and seeks to ensure periodic refreshment through a combination of a mandatory retirement age and term limits. By

GOVERNANCE OF THE CORPORATION

limiting the age and tenure of directors, the Board ensures that the Corporation will benefit from a balanced mix of long-term institutional knowledge, fresh ideas, and independence from management, while promoting director engagement and mitigating against complacency. To that end, the Corporation's Bylaws require a director to retire at age 72 and, with certain limited exceptions for directors in office as of January 1, 2020, limits director tenure to a maximum of 15 years, in the aggregate. For more information regarding the director retirement and tenure policy, please refer to the Nominating and Corporate Governance Committee Policy and Charter available on the Corporation's website.

Director Independence

The Corporation's current Board is comprised of fourteen individuals. The Board has determined that all of the Corporation's non-executive Boardmembers are independent under Nasdaq's corporate governance listing standards, resulting in 86% of the Board being deemed independent of management. In accordance with Nasdaq listing standards, only independent directors serve on the Audit, Compensation, and Nominating and Corporate Governance Committees.

To be considered independent, a director must have no disqualifying relationships as defined by the Nasdaq listing rules, and the Board must have affirmatively determined that the director has no other relationship with the Corporation, either directly or indirectly, that would interfere with his or her exercise of independent judgment in carrying out the responsibilities of a director.

In determining the directors' independence, the Board considered both loan and non-loan transactionsbetween the Bank and the directors, their family members and businesses with whom they are associated, as well as any contributions made to nonprofit organizations with whom they are associated.

Applying the foregoing, the Board has determined that all of the directors are independent, with the exception of Rory G. Ritrievi, who serves as Chair, President, and Chief Executive Officer of the Corporation, and Kenneth J. Stephon, who serves as Chief Corporate Development Officer of the Corporation.

For more information regarding types of transactions, relationships or arrangements considered by the Board in reaching its determination that the directors are independent, please refer to "Related Person Transactions."

Board Leadership Structure

The Board is led by a Chair selected by the Board. Prior to 2021, the Nominating and Corporate Governance Committee Policy and Charter (the "N&CGC Policy") required that the role of Chair be filled by a non-executive director.Following a review of the practices of similarly situated, exchange-listed bank holding companies, the Board determined it to be advisable to update the N&CGC Policy to grant the Board the discretion to combine or separate the positions of Chair and Chief Executive Officer depending on the needs and circumstances of the Corporation as they exist from time to time.

Rory G. Ritrievi, President and Chief Executive Officer, currently serves as Board Chair. The Board believes that Mr. Ritrievi's leadership role in developing the strategic vision of the Corporation, extensive knowledge of all aspects of the Corporation's business, risks, shareholder base, employees and customers, and his intimate involvement in the Corporation's day-to-day activitiesuniquely qualify him to serve as Board Chair during this important stage of the Corporation's development, while the presence of an overwhelming majority of independent directors on the Board, coupled with a strong Lead Independent Director in Mr. Noone, enables the Board to continue to effectively provide guidance to, and oversight and accountability of, management.

The N&CGC Policy empowers the Chair to call meetings of the Board, preside over meetings of the Board and shareholders, and oversee the information provided to the Board in advance of meetings.

12

Table of Contents

GOVERNANCE OF THE CORPORATION

In the event that the Chair is an executive of the Corporation or otherwise not independent under Nasdaq listing rules, the N&CGC Policy requires that the Board elect a Lead Independent Director, who shall be independent as determined in accordance with Nasdaq listing rules and shall:

preside over meetings in the absence of the Chair;

preside over meetings of the independent directors and facilitate communications between the independent directors and the Chair;

have the authority to call meetings or executive sessions of the independent directors;

serve as the liaison between the independent directors and the Chair;

be available for consultation and direct communication with major shareholders, as appropriate;

provide input to the Chair regarding agenda items and information requested by directors; and

discharge such other responsibilities as the Board may assign from time to time.

John E. Noone currently serves as Lead Independent Director. Our independent directors meet in executive session at least once annually. An independent director meeting was held in October 2025.

Risk Oversight by Board

The Board is responsible for defining the strategic vision of the Corporation, establishing acceptable risk tolerances within which management is required to operate in order to attain identified strategic objectives, and overseeing and holding management accountable for execution of the overall strategic plan, all with a view toward maximizing shareholder value. Much of this oversight function is administered through the use of committees, which are focused on particular aspects of the Corporation and Bank's operations and functions, and the risk inherent in those operations and functions. The Board seeks to constitute its committees with Board members who possess certain expertise or skill sets complementary to that committee's oversight function. For example, the Audit Committee, which is charged with overseeing the financial risk associated with the Corporation's operations, is comprised of three Board members who qualify as a "financial expert" under the Sarbanes-Oxley Act.

In addition to the general oversight of Corporation business and operations, and recognizing the unique risks that cyber threats pose to today's financial institutions, the Board also reviews a comprehensive quarterly Enterprise Risk Management Report, prepared by the Bank's Chief Risk Officer, which includes metrics and trends on major risk areas, including cybersecurity, asset quality, interest rate risk, operations, capital adequacy, liquidity, and regulatory compliance. Additionally, the Risk Committee provides further support to the Board in its role of overseeing cybersecurity risks affecting the Corporation by focusing particularly on new and emerging threats and the Corporation's defenses and responses to those threats.

The Board also recognizes the unique risks that may be posed by virtue of an organization's compensation practices. In establishing the compensation of the Corporation's executive officers, specifically, and overseeing the compensation programs of all employees, generally, the Compensation Committee is required to consider the risks associated with the Corporation's compensation practices, to ensure that such practices do not encourage the taking of unnecessary risks.
Further, in addition to receiving regular reports from Board committees, the Board Chair and the Corporation's officers keep the full Board informed of the Corporation's business through regular meetings and by providing regular reports and other materials to Board members. For more information about the Board's committees, see "Committees and Meetings of the Corporation's Board" below.

The function of each of the Corporation's committees is described below.

Nominating and Corporate Governance Committee

Among other responsibilities, this committee identifies, evaluates and recommends to the Board candidates for election or appointment as directors; monitors and makes recommendations to the Board on matters of policies and practices relating to corporate governance; and makes recommendations to the Board with respect to amendments to the Corporation's organizational documents. All members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined by Nasdaq listing standards). Joel L. Frank serves as Chair and Bruce A. Kiefer serves as Vice Chair of this committee.

The Nominating and Corporate Governance Committee has a charter which is available under Governance Documents in the Corporate Information section under the Investors link on the Corporation's website at www.midpennbank.com.

When developing a list of potential nominees, the Nominating and Corporate Governance Committee may take into consideration names provided by shareholders, directors or executive management. Shareholders may submit a recommendation to the Nominating and Corporate Governance Committee, addressed to the Nominating and Corporate Governance Committee at the corporate address. Information is gathered concerning the potential Board member's location of business and residence, shares owned, and profession or business. Information about the individual's core competencies and personal characteristics, including integrity, expertise and enthusiasm, is also gathered to determine if the candidate meets the criteria listed in the N&CGC Policy. The Nominating and Corporate Governance Committee screens this information to narrow its search of final candidates to be interviewed. Upon completion of the interviews, the Committee makes a final recommendation to the full Board. All potential candidates are screened by the same process regardless of whether they are recommended by a director, a member of executive management, or a shareholder.

The Nominating and Corporate Governance Committee recognizes the importance of having diverse perspectives on the Board and endeavors to achieve, over time, a balanced level of diversity in the Board's overall composition. With this goal in mind, the Board has made progress over the last six years with the additions of Ms. Brumbaugh in 2019 and Mr. Hudson and Ms. Gathagan in 2021. The following matrix illustrates the core competencies determined by the Board to be exhibited by each director and nominee, as well as certain other qualifications and personal characteristics.

The transaction is to be reviewed and approved by the appropriate senior officer before being submitted to the Board for approval. Related person transactions for ongoing or continuing services can be reviewed and pre-approved withinreasonable parameters established by the Board on an as-needed basis.If the terms, pricing or conditions change so as to go outside the specified parameters cited in the request, the transactions are required to be resubmitted for review and approval.

From time to time, the Bank has engaged in and intends to continue to engage in banking and financial transactions in the ordinary course of business with the Corporation's and the Bank's officers and directors and their immediate families and companies in which they had an ownership interest of 10% or more, in each case on comparable terms as those prevailing from time to time for other customers and vendors. Loans from the Bank to such persons are made in the ordinary course of business, on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable loans with persons not related to the Bank, and do not involve more than the normal risk of collectability or present other unfavorable features. The Corporation does not extend loans to related persons.

The Bank is party to a lease agreement with an entity that is an affiliate of Mr. Noone, Lead Independent Director of the Corporation's Board, in connection with a retail branch property located in Mechanicsburg, Pennsylvania, which has a remaining initial term of 9 years. Following our 2015 acquisition of Phoenix Bancorp, Inc., the Bank assumed a lease agreement with the same entity in connection with a retail branch property located in Frackville, Pennsylvania, which has a remaining initial term of 11 years. The aggregate lease payments to such entity, of which Mr. Noone is a 98% limited partner, totaled approximately $176,500 during 2025. In determining director independence, the Board considered these lease arrangements and concluded they do not impact the independence of Mr. Noone.

Todd Ritrievi, brother of Chair, President and Chief Executive Officer Rory G. Ritrievi, has been employed by the Bank since 2022. He currently serves as Vice President, Senior Enterprise Business Analyst. In such role, Mr. Ritrievi earned compensation in excess of $120,000 in 2025, and received retirement, health and wellness benefits, all on comparable terms as those provided for other employees of the Bank. Pursuant to the Related Person Transactions Policy, our Audit Committee reviewed and approved the details of Mr. Ritrievi's employment.

Neither the Corporation nor the Bank has entered into any other material transactions, proposed or consummated, with any other director or executive officer of the Corporation or the Bank, or any associate of the foregoing persons.

PROPOSAL NO. 2: NON-BINDINGADVISORY VOTE ON EXECUTIVE COMPENSATION

In accordance with the requirements of Section 14A of the Securities Exchange Act of 1934 and the related rules of the SEC, we are holding an advisory vote on the compensation of our named executive officers. At our 2025 annual meeting, over 95% of the votes cast by our shareholders approved the compensation paid to our 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 shareholders of Mid Penn Bancorp, Inc. hereby approve the compensation of the Corporation's named executive officers, as described in the Compensation Discussion and Analysis and accompanying tabular and narrative disclosure contained in the Corporation's proxy statement for the 2026 Annual Meeting of Shareholders."

Because your vote is advisory, it will not be binding upon the Board. However, the Compensation Committee will take into consideration the outcome of the vote when considering future executive compensation arrangements.

The Board unanimously recommends a vote FOR this proposal.

Compensation Program Authority and Objectives

The Board has delegated the task of administering Mid Penn's compensation program to the Compensation Committee. The Committee's primary responsibility is to assure that the compensation structure and components for executive officers of the Corporation and its subsidiaries are designed to (i) align with the interests of our shareholders and the strategic goals of the Corporation and its subsidiaries, (ii) attract and retain highly-qualified executives who are motivated to achieve high levels of performance, both short-term and long-term, (iii) be competitive with compensation programs of peer institutions, (iv) not encourage undue risk-taking which would negatively affect the safety and soundness of the Corporation and its subsidiaries, and (v) comply with the requirements of the appropriate regulatory bodies.

In making its compensation decisions for 2025, the Compensation Committee desired to recognize the efforts of the members of the executive management team who guided the Corporation in achieving each of the foregoing milestones.

Table of Contents

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis describes the key elements of our compensation program for our named executive officers. For the year 2025, our named executive officers are:

Name

Position

Rory G. Ritrievi

Board Chair, President, Chief Executive Officer and Director of the Corporation and Bank

Justin T. Webb

Senior Executive Vice President, Chief Financial Officer of the Corporation and Bank

Scott W. Micklewright

President of Commercial and Consumer Banking and Senior Executive Vice President, Chief Revenue Officer of the Bank

Heather R. Hall

Senior Executive Vice President, Market President and Chief Lending Officer of the Bank

Joan E. Dickinson

Senior Executive Vice President, Chief Retail Officer of the Bank

Compensation Program Design Overview

The main elements of compensation for 2025 for the named executive officers were base salary, short-term incentives, restricted stock awards, and the vesting of cash retention bonuses implemented in 2022 and 2024. Such elements are consistent with the Corporation's compensation objectives to align with the long-term growth and sustained earnings objectives of shareholders, and our ability to attract, retain, and motivate highly-qualified executives.

Management's Input Involving the Compensation Program

The Compensation Committee considers the views and recommendations of the Chief Executive Officer in making compensation decisions affecting executive officers who report to him. The Chief Executive Officer's role in recommending compensation levels and compensation program elements is to develop and recommend appropriate performance measures and targets for each individual, to report on the respective individual's performance, to provide data and background material to enable the Compensation Committee to assess the labor market and to make specific recommendations on each named executive officer's respective salary. The Chief Executive Officer does not recommend his own salary and is not present during the Compensation Committee's or the Board's discussions or decisions regarding his or his team's specific compensation.

Supplementary to executive compensation peer data provided by the Corporation's independent compensation consultant, members of the Corporation's Finance and Human Resources management team periodically provide the Chief Executive Officer and the Compensation Committee with updated peer analyses, which compile compensation program data disclosed by other peer banks in their respective SEC filings, in order for the Compensation Committee to assess the competitive market for executive compensation, and the consistency of the Corporation's elements and amount and trend of executive compensation with those of similarly-profiled peer banks.

COMPENSATION DISCUSSION AND ANALYSIS

Compensation Consultant's Role in Determining Compensation

In 2025, the Compensation Committee utilized the services of Meridian Compensation Partners, an independent consulting firm that specializes in executive and board compensation. In connection with the 2025 engagement, Meridian provided relevant peer data analysis (utilizing 2024 proxy information, the most recent compensation data publicly available) and advice for consideration by the Committee in evaluating compensation of the named executive officers. The Board's objective is to compensate our executive officers at or around the 50th percentile of peers. The following peer group comprised of commercial banks with total assets ranging between $2.5 billion and $11.7 billion was used in Meridian's analysis:

First Commonwealth Financial Corporation

Peapack-Gladstone Financial Corporation

ConnectOne Bancorp, Inc. Peoples Financial Corporation
S&T Bancorp, Inc. First Bank
Flushing Financial Corporation Citizens Financial Group
Tompkins Financial Corporation LINKBANCORP, Inc.
Univest Financial Corporation CNB Financial Corporation

Results of Shareholder "Say-on-Pay" Vote in Determining Compensation

Each year, the Corporation asks its shareholders to cast a non-binding advisoryvote on the compensation of our named executive officers, known as a "say-on-pay" vote.At the 2025 Annual Meeting, the Corporation's shareholders approved the compensation of our named executive officers by an overwhelming majority of more than 95% of votes cast. The Compensation Committee considers the shareholders' voted level of approval of our executive compensation practices relative to both the current year, and say-on-pay votingtrends over several years, as a key input when considering whether to significantly change the Corporation's compensation policies and practices. The strong past-shareholder support of our compensation philosophy, combined with the strong retention of the executive management team, has led the Compensation Committee to conclude that a material change to such philosophy is not currently necessary, although the Committee continues to seek the advice of an independent compensation consultant, as well as data from management, to ensure that the Corporation's pay practices are consistent with current market conditions and best practices.

CEO Pay Ratio Disclosure

In 2015, the SEC adopted a rule requiring certain public companies to disclose the ratio of the total compensation of the CEO to the median compensation of its other employees.

For the Corporation, the median employee was determined using a census of all full-time and part-time employees as of November 30, 2025, which totaled 743 personnel excluding the CEO. The annual total compensation for all employees on this census was calculated using the same pay elements shown for the CEO in the "Summary Compensation Table - 2025". The primary elements of this 2025 total compensation calculation included base salary/wages, bonuses and incentive compensation, employer matching contributions to the Corporation's 401(k) plan, restricted stock awards, auto allowances, employer-paid life insurance premiums and nonqualified deferred compensation. For full-time employees who were hired during 2025, the base salary/wages element was annualized to determine the respective individual's total compensation.

28

Table of Contents

COMPENSATION DISCUSSION AND ANALYSIS

As disclosed in the "Summary Compensation Table - 2025," the total compensation of the CEO for 2025 was $2,209,726. The 2025 total compensation of the median employee was $64,093. The resulting ratio of the CEO's total compensation to that of the median employee is 34 to 1.

Components of Compensation

Base Salary

Base salary levels are set to attract and retain executives who can further the Corporation's and Bank's strategic objectives and who are motivated to achieve high levels of performance, both short-term and long-term. Base salary is the most significant component of the named executive officers' compensation, and the Compensation Committee reviews it every year to determine whether the salary for each respective named executive officer is at an appropriate level when considering the relevant inputs. As mentioned above, the Chief Executive Officer reviews each named executive officer's performance, other than his own, in making salary recommendations to the Compensation Committee. The Chief Executive Officer and the Compensation Committee consider each named executive officer's general management performance; policy, procedure, and regulatory compliance; public relations; strategic objectives management; length of service with the Corporation and Bank; and the named executive officer's position and areas of responsibility in making its determination of the appropriate level of base salary. The Compensation Committee reviews the Chief Executive Officer's performance in making a salary recommendation to the Board.

Executive Annual Incentive Plan; Short-Term Incentives and Bonuses

On January 22, 2025, the Board approved the Mid Penn Bancorp, Inc. Executive Annual Incentive Plan, effective for the 2025 fiscal year (the "AIP"). The AIP is intended to optimize the profitability and growth of the Corporation through incentives consistent with the Corporation's goals in order to link and align the personal financial interests of the participants with the overall financial performance of the Corporation, and to provide flexibility to the Corporation in its ability to motivate, attract and retain the services of individuals who make contributions to the Corporation's overall success. Each of the Corporation's named executive officers is eligible to participate in the AIP.

The AIP authorizes the payment of annual cash and equity bonus awards, designated as a percentage of base salary, subject to performance objectives that must be satisfied during each plan year (which is the calendar year) for the participant to earn an annual bonus award. The base salary used in incentive calculations is the named executive officer's annualized salary rate as of the last day of the relevant fiscal year. Payment of the annual bonus award is also contingent on the Corporation's and/or the named executive officer's overall performance level being satisfactory, as determined in the sole discretion of the Compensation Committee.

The Compensation Committee structured payouts under the AIP in 2025 to be based on measurable performance against specific financial targets that the Compensation Committee believes to be key drivers of shareholder value. The financial performance metrics account for 60% (subject to upward adjustment upon achievement of maximum financial performance) of the 2025 AIP annual bonus award available to named executive officers. The remaining 40% of the named executive officer's potential annual bonus award as a percentage of their base salary may be awarded at the discretion of the Compensation Committee. The discretionary portion of the award gives the Compensation Committee the flexibility to reward strong individual performance of the named executive officers in their roles and recognize the Corporation's strategic goals achieved during the fiscal year.

Award determinations are made by the Compensation Committee as soon as practicable following the end of the plan year and paid to each named executive officer no later than March 15th.

Of which 60% is comprised of the performance-based component, with the remaining 40% payable at the discretion of the Compensation Committee.

The specific performance objectives are determined annually by the Compensation Committee and communicated to the named executive officer, but generally may include objective targets on financial performance and profitability growth, such as net income, efficiency ratio and tangible book value growth, and subjective performance objectives, such as particular qualitative factors for the named executive officer based on his or her duties to the Corporation. Each performance objective may be weighted based on priority as a contribution to the total performance bonus award payable to the named executive officer. For 2025, the Compensation Committee selected the following: (1) Earnings Per Share; (2) Operating Efficiency Ratio; and (3) Tangible Book Value growth. Operating Efficiency Ratio is calculated as total noninterest expense, less merger and acquisition expenses, amortization of intangibles, foreclosed asset expenses and other non-operatingexpenses, divided by the sum of non-interestincome and net interest income, adjusted to include the tax equivalent income on tax exempt income from investments and loans. These financial metrics were selected because the Compensation Committee considers them the most significant indicators of financial performance and drivers of shareholder value.

If the target performance levels are attained, the incentive bonus awards would be initially earned at target levels. If performance is below the threshold for a given performance goal, no incentive bonus would be paid for that goal. Performance above maximum for a given goal would result in payout at maximum for that goal.

The target performance levels and actual performance for 2025 with respect to the performance objectives were as follows:

In determining financial performance for 2025, the Compensation Committee determined to exclude merger-related expenses and the dilutive effective to tangible book value generated by the acquisition of William Penn Bancorporation and the issuance of the Corporation's common stock to former William Penn shareholders to avoid negatively impacting AIP participants for the achievement of the Corporation's strategic objectives, as well as other non-recurringincome and expenses consistent with the disclosures contained in the Corporation's quarterly earnings releases.

COMPENSATION DISCUSSION AND ANALYSIS

For 2025, the Corporation performed at the "maximum" level (as adjusted) for both the Earnings Per Share and Tangible Book Value Growth categories, and at the "target" level for Operating Efficiency Ratio.

For 2025, the Compensation Committee paid each named executive officer the full discretionary portion of the cash bonus and equity bonus award. The Compensation Committee came to this decision following its review of relevant peer company and market data, discussions with the Corporation's compensation consultant, and the achievement of the maximum financial performance metrics under the AIP for 2025.

Annual Cash Incentive Awards

Each named executive officer's cash incentive bonus award is targeted at a specified percentage of base salary, as described above and determined by adjusting the target cash bonus award by the level of achievement of the 2025 AIP financial metrics. For the year ended December 31, 2025, Adjusted Earnings Per Share (non-GAAP)was $3.03, compared to $2.70 at target, Operating Efficiency Ratio was 59.15%, compared to 62.85% at target, and Adjusted Tangible Book Value growth was 9.17%, compared to 7.80% at target. The Compensation Committee believes that cash awards under the AIP rewards the named executive officer's achievement in the short-term of individual and corporate goals that align with our strategic plan and contributes to the Corporation's overall success.

The following table summarizes the cash-incentive bonus award opportunity available, and actual payments made, to named executive officers for 2025 performance.

Annual Equity Incentive Compensation Awards

Each named executive officer's equity incentive bonus award is targeted at a specified percentage of base salary, as described above and determined by adjusting the target equity cash bonus award by the level of achievement of the 2025 AIP financial metrics. For the year ended December 31, 2025, Adjusted Earnings Per Share (non-GAAP)was $3.03, compared to $2.70 at target, Operating Efficiency Ratio was 59.15%, compared to 62.85% at target, and Tangible Book Value growth was 9.17%, compared to 7.80% at target.

Equity bonus awards are paid in the form of restricted stock, subject to a three-year vesting period, and issued under the Corporation's 2023 Stock Incentive Plan. The Compensation Committee believes that equity awards under the AIP effectively align the interests of the named executive officers with those of our shareholders by providing individuals who have responsibility for management and growth of the Corporation with an opportunity to increase their ownership of the Corporation's common stock, to have a meaningful interest in the future of the Corporation and sustained shareholder value creation, and discourages excessive risk taking.

All awards issued under the executive annual incentive plan are subject to the Corporation's Clawback Policy.

2024 Informal Compensation Plan

In 2024 the Corporation maintained an informal executive compensation plan pursuant to which our named executive officers were eligible to receive short-term cash and equity incentives for the achievement of corporate and individual performance goals. In order to receive a payment under the plan in 2024, the named executive officer had to be employed prior to September 30, 2023, and on the date of payout, and both the corporate and individual performance goals, which include actions that can only be taken by the named executive officer for the respective performance period, must be achieved. The short-term incentives for performance in 2024 and for the first quarter of 2025 paid to named executive officers were awarded in the first quarter of 2025. A key input considered by the Compensation Committee in determining whether to recommend an award and the amounts thereof were the actual earnings performance of the Corporation for the full year of 2024 and the first quarter of 2025 compared to the Board-approved targeted net income available to common shareholders for the respective periods as well as other non-financialtargets. The Board's targeted net income for the first quarter of 2025 was $9,974,000 while actual net income for that period was $13,742,000. The Compensation Committee believed that the Board-approved earnings targets were aggressive and difficult to achieve, particularly in the difficult operating environment. As a result of this performance relative to the Board-approved targets, and considering each named executive officer's respective performance goals and achievements, the Compensation Committee awarded cash bonus compensation to Mr. Ritrievi, Mr. Webb, Mr. Micklewright, Ms. Hall, and Ms. Dickinson in the amount of $400,000, $170,000, $155,000, $110,000 and $100,000, respectively.

Equity Incentive Plans

The Corporation has continued to make restricted common stock awards to named executive officers, other members of management, and directors, consistent with past practice. Restricted stock is common stock granted to an employee or director that does not vest until specific conditions are met. Typical conditions for employees receiving restricted stock grants include performance goals for the individual or the Corporation, and for the vesting thereof, the individual being required to remain employed with the Corporation or Bank for a specific number of years. Once the conditions are met, then the common stock vests and the employee obtains the shares without restrictions. The Board believes that restricted stock awards can serve as an important element in attracting and retaining employees and directors whom the Board expects to contribute to the Corporation's growth and success both in the near-term, and over the longer-term vesting period and beyond, to realize benefits in the growth on the value of the Corporation's stock in alignment with shareholder interests. By compensating employees and directors with shares of Corporation common stock, the employees and directors have additional incentive to ensure that the

32

Table of Contents

COMPENSATION DISCUSSION AND ANALYSIS

Corporation is successful. Based on the recommendations of the Compensation Committee, the Board determines to whom specifically it grants restricted stock, as well as the timing, vesting schedule, and number of shares subject to the award. Historically, awards have been made under the Mid Penn Bancorp, Inc. 2014 Restricted Stock Plan, which expired by its terms in 2024.

At the 2023 Annual Meeting, the Corporation's shareholders approved a new, omnibus Stock Incentive Plan. This new plan replaces the 2014 Restricted Stock Plan and provides the Corporation additional flexibility in designing its equity compensation programs by authorizing the issuance of stock options, restricted stock, stock appreciation rights, deferred stock units, and performance shares. The number of shares of common stock which may be issued under the Stock Incentive Plan may not exceed 350,000 shares. The Compensation Committee may suspend, terminate or amend the Stock Incentive Plan at any time; provided, that no amendment may be made without shareholder approval if such approval is required by law, agreement or the rules of any exchange upon which the Corporation's shares of common stock are listed. In addition, no such amendment, suspension or termination may impair the rights of participants with respect to their outstanding awards without their consent.

All awards issued under the Stock Incentive Plan are subject to the Corporation's Clawback Policy.

Retention Incentives

In 2022, a three-year retention bonus was awarded to Mr. Ritrievi. In 2024, Messrs Webb and Micklewright and Mss. Hall and Dickinson were awarded two-yearretention bonuses and a three-year retention bonus was awarded to Mr. Ritrievi. While advanced in full on the grant date, these bonuses were structured such that they vest over a two-year orthree-year period (one-half or one-thirdon each anniversary of the grant date), subject to the executive's continued employment. In the event that the executive's employment is terminated for cause or the executive resigns prior to the final anniversary of the grant date, the executive is required to repay any unvested portion plus interest on the unvested portion. Amounts that vested in 2025 are reflected in the Summary Compensation Table below.

Benefit Plans Available for All Employees

Certain benefit plans, including group insurance plans as described below, are not tied to Bank or individual performance. The cost of providing such plans to all eligible employees, including named executive officers, is viewed as a cost of doing business and not taken into account when determining specific compensation of the named executive officers.

Group Insurance Plans

The named executive officers participate in group insurance benefit plans that are generally available to all employees. These plans include group life insurance, group disability, health insurance and dental and vision benefits. Such plans are standard in the industry and in the geographic area for all industries, as well as necessary to compete for talented employees at all levels of the Bank. Under the group life insurance plan, Mr. Ritrievi was unable to get the same percentage of coverage as other employees due to the maximum benefit provided for in the plan. In order to afford Mr. Ritrievi the same long-term disability coverage as other employees, an individual policy was purchased with the premium (and Mr. Ritrievi's associated income tax liability) reimbursed by the Bank. Additionally, Mr. Ritrievi and the named executive officers are also provided a supplemental long-term disability plan to cover the same percentage of coverage as other employees due to the maximum benefit provided for the long-term disability plan.

Retirement Plan

In an effort to encourage its employees, including the named executive officers, to save for retirement, the Bank has established a tax-qualified 401(k) retirementplan for employees. The Bank believes that it is important to assist employees in saving for retirement and believes that by providing a mechanism to save for retirement, and through Bank matching of certain employee contributions, the Bank is providing the named executive officers with a reasonable and industry-expected incentive to continue in the employ of the Bank.

COMPENSATION DISCUSSION AND ANALYSIS

Employee Stock Purchase Plan

At the 2023 Annual Meeting, shareholders approved a new, tax-qualifiedemployee stock purchase plan. The new, tax-qualifiedplan replaced the plan that had been in place since January 1, 2011. The new employee stock purchase plan provides eligible employees of the Corporation or the Bank, including the named executive officers, with an opportunity to purchase shares of common stock of the Corporation at a discounted price through payroll deductions. The Plan provides participants with a convenient method to acquire an interest in the common stock of the Corporation and realize the benefits of their efforts toward the long-term performance and success of the Corporation in alignment with our shareholders' interests.

Company Vehicle

Each of the named executive officers is provided a company vehicle. Provision of a company vehicle is standard in the financial services industry as executive officers frequently meet clients and business associates at locations offsite of the Corporation's offices. Each executive's personal use of the company vehicle is tracked and calculated for inclusion in their taxable and total compensation.

Accounting and Tax Treatments

The Compensation Committee, in consultation with Finance management, considers the accounting and tax consequences of the compensation program and its elements, both for the Corporation and the individual, prior to making any changes to the compensation structure. Section 162(m) of the Internal Revenue Code limits the deduction of compensation paid to the named executive officers if certain thresholds are exceeded. As a result of the Company's performance-based incentive payouts, time-based equity vesting, and retention awards granted in prior years, the total compensation for certain executives will exceed the $1 million deductibility threshold for the current fiscal year. Consequently, the Company will be unable to deduct a portion of this compensation for federal income tax purposes. While the Compensation Committee considers the deductibility of compensation under Section 162(m) when making pay decisions, it believes that maintaining a competitive and performance-driven executive compensation program is in the best interests of shareholders. Therefore, the Committee may approve compensation that is not fully deductible when it determines such arrangements further the Company's strategic objectives.

Material Differences in Named Executive Officers' Compensation

The differential between salary levels for each of the named executives is primarily driven by their respective positions, with consideration also given to the experience and time in their respective positions.

Employment, Change in Control, and Supplemental Executive Retirement Plan Agreements

Employment Agreements

Each named executive officer is party to an employment agreement with the Corporation and the Bank, which, unless earlier terminated, automatically renews on each September 6 for a total of the next three years for Messrs. Ritrievi, Webb and Micklewright, and two years for Mss. Hall and Dickinson. The employment agreements provide that Messrs. Ritrievi, Webb, Micklewright, and Mss. Hall and Dickinson will receive an initial annual base salary of $625,000, $350,000, $350,000, $325,000 and $295,000, respectively, which may be increased from time to time. In addition to base salary, the employment agreements provide for, among other things, participation in bonus programs and other benefit plans and arrangements applicable to executive officers of the Bank.

In the event of the executive's involuntary termination of employment without "cause" or in the event of a voluntary termination for "good reason" (each as defined in the employment agreement), the executive would become entitled to continue to receive the executive's base salary in effect on the date of termination for a period equal to the greater of the remaining employment term or six months and participate in the Bank's life, disability, medical/health insurance and other benefits substantially similar to those which the executive was receiving during the year prior to

34

Table of Contents

COMPENSATION DISCUSSION AND ANALYSIS

the date of termination for the same period described above immediately following the date of termination, or a cash payment equal to the estimated after-taxcost to obtain such benefits, or substantially similar benefits.

The employment agreement and the executive's employment may be terminated for "cause" (as defined in the employment agreement) by written notice from the Corporation or the Bank. If the employment agreement is terminated for cause, the executive's rights under the employment agreement terminate as of the effective date of termination. The employment agreement also terminates without further payments to the executive as of the termination date in the event of the executive's voluntary termination of employment (other than for good reason) or death. In the case of the executive's "disability" (as defined in the employment agreement), the executive will become eligible for employer-provided short-term and/or long-term disability benefits, or worker's compensation benefits, in which case the Bank's obligation to pay the executive their annual base salary shall be reduced by such benefits. Under certain other types of disabilities set forth in the employment agreement, the employment agreement will terminate six months following a determination related to such disability by the Corporation's board of directors.

In the event that the executive is involuntarily terminated for cause or voluntarily terminates employment without good reason, the executive will be subject to a twelve-month non-solicitationcovenant (applicable to both customers and employees). In the event that the executive is involuntarily terminated without cause or voluntarily terminates employment for good reason, the executive will be subject to a twelve-month non-solicitationcovenant with respect to employees and a six-month non-solicitationcovenant with respect to customers.

The employment agreement with each executive provides that, in the event that the payments to be received by the executive, when taken together with payments and benefits payable to or on behalf of the executive under any other plans, contracts or arrangements, would constitute an excess parachute payment under Internal Revenue Code Section 280G, the executive may elect to reduce the payment actually received in order to reduce or eliminate the impact of the excise tax under Section 4999 of the Code. The executive is not entitled to a "gross-up"payment to reduce the effect of the tax under Section 4999 of the Code.

Mr. Ritrievi's employment agreement further provides that he shall serve on the Bank's board of directors and shall be re-nominatedfor election to the Corporation's board of directors, with the Corporation's board of directors recommending such election to its shareholders, for any annual meeting of shareholders at which the class of directors in which Mr. Ritrievi is serving will be elected. Mr. Ritrievi's service as director of the Corporation, the Bank and any affiliate or subsidiary shall immediately terminate upon the termination of his employment for any reason.

Change in Control Agreements

The Corporation has entered into change in control severance agreements with each of its named executive officers. Each agreement has a "double-trigger" payment feature requiring both a change in control of the Corporation and the involuntary termination of the executive's employment without cause or voluntary termination of employment by the executive for "good reason" in order for the benefit to be payable.

More specifically, in the event an executive's employment is terminated on or within twelve months after a "change in control" during the term of the agreement either by the Corporation, other than for death or disability or for a reason other than "cause" (as defined in the agreement), or by the executive after the occurrence of certain specified events constituting "good reason" (described below), the Corporation will pay the executive a lump-sum cashpayment. That payment is equal to 2.99 times the executive's highest annual base salary in effect during the twelve months preceding the executive's termination of employment with respect to Mr. Ritrievi, 2.75 times with respect to Messrs. Webb and Micklewright, and 2.50 times with respect to Mss. Hall and Dickinson. In addition, the executive and the executive's beneficiaries will remain eligible to participate, on the same terms and conditions as apply from time to time to the Corporation's executive management team, medical, vision and dental programs for 33 months for Messrs. Webb and Micklewright, 30 months for Mss. Hall and Dickinson, and three years for Mr. Ritrievi, or a cash payment equal to the estimated after-tax costto obtain such benefits, or substantially similar benefits, within thirty days following the executive's termination. In the event that the executive is involuntarily terminated for cause or voluntarily terminates employment during the term of the agreement, the executive will be

2026 PROXY STATEMENT

Table of Contents

COMPENSATION DISCUSSION AND ANALYSIS

subject to a twelve-month non-solicitation covenant(applicable to both customers and employees). In the event that the executive is involuntarily terminated without cause or voluntarily terminates employment for good reason, the executive will be subject to a twelve-month non-solicitationcovenant with respect to employees and a six-month non-solicitationcovenant with respect to customers.

The specified events of "good reason" permitting an executive to terminate employment following a change in control and receive payments or benefits under the agreement include: (i) a material diminution in executive's authority, title, duties or responsibilities following a change in control from the authority, title, duties or responsibilities existing as of a change in control; (ii) requirement that the executive perform a substantial portion of his or her duties at a location more than 50 miles from executive's principal executive office on the date of the agreement; or (iii) a material decrease in executive's base salary and other compensation and benefits existing as of a change in control.

If, within ninety days after a termination of an executive's employment that entitles such executive to payments under the agreement, the Corporation's Board becomes aware of facts that, if known during the executive's employment, it reasonably believes would have justified termination of such executive's employment for cause (as defined in the agreement), the Corporation may refrain from paying any unpaid amounts due under the agreement or require the executive to promptly, but in no event less than ninety days after notice to such executive of such determination by the Corporation's Board, repay any amounts previously paid or the value of any benefits previously received under the agreement.

The agreement with each executive provides that, in the event that the payments to be received by the executive, when taken together with payments and benefits payable to or on behalf of the executive under any other plans, contracts or arrangements, would constitute an excess parachute payment under Internal Revenue Code Section 280G, the executive may elect to reduce the payment actually received in order to reduce or eliminate the impact of the excise tax under Section 4999 of the Code. The executive is not entitled to a gross up payment to reduce the effect of the tax under Section 4999 of the Code.

Each agreement is for a term of three years and renews for an additional year on each anniversary of the respective named executive officer's signing, absent notice of non-renewal fromeither party.

Supplemental Executive Retirement Plan Agreements

The Bank is a party to supplemental executive retirement plan agreements ("SERPs") with each of its named executive officers. Each SERP provides for the monthly payment of a fixed cash benefit over a period of fifteen (15) years, commencing on the first day of the month following the executive's separation from service: (i) occurring on or after reaching normal retirement age (age 70); (ii) due to disability; (iii) due to death; or (iv) within two (2) years following a change in control of the Bank. The terms of the SERPs are identical for each executive, except for the amount of the annual benefit and the timing of vesting of the benefit, which is as follows: Mr. Ritrievi-$190,000 (approximately 85% vested with the remainder to vest ratably over the next year); Messrs. Micklewright and Webb-$125,000 and increased by a factor of 2.0% each year beginning on January 1, 2027 (approximately 80% vested with the remainder to vest over the next year); Ms. Hall-$125,000 (approximately 66% currently vested with the remainder to vest ratably over the next two years); and Ms. Dickinson-$125,000 (approximately 66% currently vested with the remainder to vest ratably over the next two years). In 2025, Mr. Ritrievi was granted an additional SERP (the "2025 SERP") which provides for the monthly payment of a fixed cash benefit over a period of fifteen (15) years, commencing on the first day of the month following the later of Mr. Ritrievi's separation from service or upon attaining normal retirement age (age 73): (i) upon termination of employment on or after attaining normal retirement age; (ii) upon early termination by the Bank or Mr. Ritrievi other than for cause; or (iii) upon termination of employment within two (2) years following a change in control of the Bank. Alternatively, the monthly payment of a fixed cash benefit over a period of fifteen years will commence upon Mr. Ritrievi's earlier disability or death. The annual benefit is $404,480 and increased by a factor of 2.0% beginning in the year Mr. Ritrievi attains normal retirement age (age 73) (approximately 15% vested with the remainder to vest ratably over the next ten (10) years). The normal retirement benefit becomes fully vested upon a termination following a change in control or Mr. Ritrievi's disability. In the event of Mr. Ritrievi's termination of employment other than for cause or by Mr. Ritrievi for good reason, vesting is accelerated by three years. The Board of Directors of the Bank reserves the right to increase the amount of the benefit from time to time, in its discretion.

Table of Contents

COMPENSATION DISCUSSION AND ANALYSIS

In the event that any payment owing under the SERP and the 2025 SERP would constitute an excess parachute payment under Section 280G of the Internal Revenue Code, each SERP and the 2025 SERP provides the executive with the same election right as that described under the heading "Change in Control Agreements" above. The executive is not entitled to a gross up payment to reduce the effect of the tax under Section 4999 of the Code.

The SERP and the 2025 SERP also contains non-competition and non-solicitation covenants.A violation of such covenants, except in limited circumstances, would result in the forfeiture of any unpaid benefits to the executive.

Split Dollar Agreement

The Corporation has purchased bank owned life insurance on the life of Mr. Ritrievi and has entered into a split dollar life insurance agreement that provides to Mr. Ritrievi's designated beneficiary a share in death proceeds payable under one or more life insurance policies owned by the Bank in the event of Mr. Ritrievi's death while he is still employed by the Bank. The amount payable to Mr. Ritrievi's beneficiaries is the lesser of: (i) the 2025 SERP differential, which is equal to the amount listed on Schedule A of the split dollar agreement opposite the year in which Mr. Ritrievi died, minus the vested death benefit payable under the 2025 SERP; and (ii) the net death proceeds, which is defined as the total death proceeds minus the greater of the cash surrender value of the policies and the aggregate premiums paid by the Bank, plus the vested 2025 SERP death benefit. The split dollar agreement will terminate upon Mr. Ritrievi's separation from service.

Risk Analysis of Compensation Practices and Policies

The Compensation Committee reviewed the compensation policies and practices for all employees and determined that they do not create risks that are reasonably likely to have a material adverse effect on the Corporation or Bank.

Compensation Committee Report

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis with management, and, based on the review and discussions, the Compensation Committee recommended to the Board that the Compensation Discussion and Analysis be included in the Corporation's proxy statement.

Compensation Committee Interlocks and Insider Participation

The Corporation has no Compensation Committee interlocks. Messrs. DeSoto, Evans, Frank, and Noone and Mss. Brumbaugh and Gathagan constitute all of the directors who served on the Compensation Committee at any time during 2025. Each of them is an independent outside director. None of them is a current or former officer or employee of the Corporation. During 2025, the Bank engaged in customary banking transactions and had outstanding loans to certain of its directors, executive officers, members of the immediate families of certain directors and executive officers and their associates. These loans were made in the ordinary course of business and were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with persons not related to the lender. In the opinion of management, these loans do not involve more than normal risk of collectability or present other unfavorable features. Non-banking relationships that members of the Compensation Committee have had or maintain with the Corporation or Bank are described under the heading, "Related Person Transactions." Rory G. Ritrievi, Chair, President, and Chief Executive Officer of the Corporation, attended Compensation Committee meetings only when and to the extent requested by the Committee. Mr. Ritrievi did not participate in determining his own compensation.

EXECUTIVE COMPENSATION

The following discussion provides details of the various components of executive compensation.

Summary Compensation Table

The following table summarizes the total compensation awarded or earned for services in all capacities to the Corporation or the Bank for the years ended December 31, 2025, December 31, 2024, and December 31, 2023, for the named executive officers.

The presentation includes, for 2025, both a cash bonus paid to executives in early 2025 based upon fiscal year 2024 results, reflected in the "Bonus" column, and a cash bonus paid to executives in early 2026, based upon fiscal year 2025 results, reflected in the "Non-Equity Incentive Plan Compensation" column. The reason for this is that the 2024 bonus was completely discretionary whereas the 2025 bonus was awarded pursuant to the formal AIP Plan that became effective January 1, 2025. Accordingly, the aggregate amount of cash bonus paid reflects compensation for two fiscal years, not one.

This amount includes the vested portion of a three-year retention bonus awarded to Mr. Ritrievi in 2022. In 2024 Messrs. Webb and Micklewright and Mss. Hall and Dickinson were awarded two-year retention bonuses and a three-year retention bonus was awarded to Mr. Ritrievi described under "Retention Bonuses." Mss. Hall and Dickinson were not named executive officers for the fiscal years 2023 and 2024. Accordingly, compensation for those years is not included. This amount also includes cash incentive payments paid to each NEO pursuant to the informal executive compensation plan for the Company's performance in the 2024 fiscal year and first quarter of 2025, paid to each NEO in the first quarter of 2025, described under "Executive Annual Incentive Plan; Short-Term Incentives and Bonuses, 2024 Informal Compensation Plan."

We calculated these amounts using the provisions of ASC Topic 718. Amounts represent the full grant date fair value of the restricted stock awards granted June 1, 2021, April 1, 2022, April 3, 2023, and April 1, 2024. Depending upon the terms of each respective grant, some percentage of the shares of restricted stock granted vests on each anniversary of the date of grant (each, a "vesting tranche"), but only if such named executive officer remains continuously employed through the applicable anniversary date. The vesting periods range from one year to four years. We include the assumptions used in the calculation of these amounts in the footnotes to our audited financial statements included in our respective Annual Report on Form 10-Kfor the fiscal years ended December 31, 2022, 2023, and 2024.

Retirement Plans

The Corporation does not maintain a defined benefit pension plan for its employees. In connection with his service on the Board, however, Mr. Ritrievi was a participant in the Director Retirement Plan, which plan was terminated and paid out in 2024.

The Bank maintains the Mid Penn Bank Retirement Plan (hereafter, the "Retirement Plan"), which is a defined contribution plan and covers all eligible Bank employees, including the named executive officers. The Retirement Plan also has a 401(k) provision for all eligible Bank employees. Eligible employees are entitled to receive a share of the Bank's discretionary profit-sharing contribution to the Retirement Plan for a year if they are Bank employees on December 31 of that year. For 2025, the Board approved a 401(k) safe harbor matching contribution rate of 100% on the first 4% of the employee deferral contributions plus 50% on the next 1% of the employee deferral contributions, up to a maximum Bank contribution of 4.50%. The Board may adjust its matching rate on an annual basis at its discretion.

The Board makes discretionary contributions to the Retirement Plan based on the recommendation of the Compensation Committee. The Corporation did not make a discretionary profit-sharing contribution for 2025. Distribution under the Retirement Plan can be made to participating employees upon retirement, either normal or early retirement as defined in the Retirement Plan's provisions, at death or disability of the participating employee or upon severing employment if either partially or fully vested. The Retirement Plan's discretionary contributions and non-safe harborcontributions are subject to vesting at the rate of 20% per year after the first two years of service with 100% vesting after six full years of service. The 401(k) safe harbor matching contributions are 100% vested when made. Participants are always 100% vested in their own 401(k) contributions. As of December 31, 2025, each of the named executive officers, was 100% vested in their discretionary accounts.

On April 1, 2025, the Corporation awarded restricted stock to Messrs. Ritrievi, Webb, Micklewright, and Mss. Hall and Dickinson under the Restricted Stock Plan, which is described above under the caption "Restricted Stock Plan." Each named executive officer's shares vest 25% on each anniversary of the date of grant (each, a "vesting tranche"), but only if the named executive officer remains continuously employed through the applicable anniversary date. In general, a participant in the Restricted Stock Plan will forfeit shares then unvested upon his or her termination of employment for any reason. Upon a participant's death, the participant will vest in any unvested shares that would have vested in that calendar year.

During fiscal year 2025, the Corporation did not grant stock option awards to our named executive officers. Additionally, the Corporation does not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation for equity awards.

PROPOSAL NO. 3: RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS THE CORPORATION'S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2026

  Table of Contents

AUDIT COMMITTEE REPORT 44
CHANGE IN INDEPENDENT REGISTERED ACCOUNTING FIRM 46

The Audit Committee of the Board has appointed Deloitte & Touche LLP as its independent registered public accounting firm for the year ending December 31, 2026. Services provided to the Corporation and the Bank by RSM US LLP in 2025 and 2024 are described under the "Audit Committee Report," below.

The Corporation is asking its shareholders to ratify the selection of Deloitte & Touche LLP as its independent registered public accounting firm. Although this ratification is not required by the Corporation's Bylaws or otherwise, the Board is submitting the selection to its shareholders for ratification as a matter of good corporate practice.

The Board unanimously recommends that shareholders vote FOR ratification of the appointment of Deloitte & Touche LLP as the Corporation's independent registered public accounting firm for 2026.

No determination has been made as to what action the Audit Committee would take if shareholders do not ratify the appointment. In the event that shareholders do not ratify the appointment of Deloitte & Touche LLP, the Audit Committee would take a number of factors into account in determining its course of action, including its evaluation of the services provided by Deloitte & Touche LLP and the remaining term of the Corporation's engagement of Deloitte & Touche LLP. Even if the selection is ratified, the Audit Committee in its discretion may select a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of the Corporation.

Representatives of Deloitte & Touche LLP are expected to be present at the annual meeting. They will have the opportunity to make a statement if they desire to do so, and are expected to be available to respond to appropriate shareholder questions. We do not expect that representatives of RSM US LLP will attend the annual meeting.

AUDIT COMMITTEE REPORT

The Board adopted a written charter for the Audit Committee. The Audit Committee Charter is available under Governance Documents in the Corporate Information section under the Investors link on the Corporation's website at www.midpennbank.com. As required by the charter, the Audit Committee, in fulfilling its oversight responsibilities regarding the audit process:

reviewed and discussed the fiscal year 2025 audited financial statements, and the management report on internal controls over financial reporting, with both management and the independent registered public accounting firm, RSM US LLP;

discussed with the independent registered public accounting firm, the matters required to be discussed by PCAOB Audit Standard 1301 (Communications with Audit Committees) as issued by the Public Company Accounting Oversight Board; and

reviewed the written disclosures and the letter from the independent registered public accounting firm required by the Public Company Accounting Oversight Board Independence Rules and discussed with the independent auditors any relationships that may impact their objectivity and independence.

Based upon the review and discussions referred to above, the Audit Committee recommended to the Board that the audited consolidated financial statements for the year ended December 31, 2025, be included in the Corporation's annual report and filed with the SEC.

All audit and permissible non-auditservices provided by RSM US LLP were pre-approvedby the Audit Committee. Under the charter, a de minimis exception is provided whereby pre-approval maybe waived for non-audit servicesthat meet all of the following requirements:

the aggregate amount of all such services is not more than five percent of the total amount of fees paid to the independent auditor during the year in which the services are provided;

ADDITIONAL INFORMATION
DELINQUENT SECTION 16(a) REPORTS
The officers and directors of the Corporation and beneficial owners of greater than 10% of the common stock are required to file reports on Forms 3, 4 and 5 with the SEC disclosing beneficial ownership and changes in beneficial ownership of Corporation common stock. SEC rules require disclosure in the Corporation's Proxy Statement of the failure of an officer, director or 10% beneficial owner of the common stock to file a Form 3, 4, or 5 on a timely basis. Based on the Corporation's review of ownership reports, no officer or director failed to file ownership reports on a timely basis for the year ended December 31, 2025, except that Director Albert J. Evans made one late filing on May 19, 2025 for a purchase that occurred on May 13, 2025. The Corporation has determined that this late filing was due to an administrative oversight.
PAY VERSUS PERFORMANCE
In accordance with the SEC's new disclosure requirements regarding pay versus performance ("PVP"), the following information is being provided to illustrate the relationship between compensation actually paid ("CAP") to an executive (as defined by the SEC), and certain financial performance measures of the Corporation.
The Compensation Committee makes its compensation decisions independent of the SEC's PVP disclosure requirements. For further information on how the Corporation aligns executive compensation with the Corporation's financial performance, see "Compensation Discussion & Analysis" on page 26 above.
Pay Versus Performance Table
The following table sets forth information concerning the compensation of our principal executive officer ("PEO") and other named executive officers ("NEOs") for each of the fiscal years ended December 31, 2025, 2024, 2023, 2022, and 2021 and our financial performance for each such fiscal year, as computed in accordance with SEC rules, followed by a table reconciling the compensation disclosed in the Summary Compensation Table ("SCT"), and the compensation required to be disclosed as CAP:

The peer group used in 2025 are the peers identified by our compensation consultants, Meridian Compensation Partners, disclosed in the section titled "Compensation Consultant's Role in Determining Compensation." The peer group used for 2025 included the addition of ten banks and the removal of nine banks. The changes to the peer group were primarily driven by changes in peer bank asset size, with banks added or removed to create a peer group more similar in asset size to the Corporation. Peer Group Total Shareholder Return for 2024, 2023, 2022, and 2021 for the former peer group, Newcleus Compensation Partners, was $111.87, $101.78, $97.00, $140.17, and $74.23, respectively.

Tabular List of Performance Measures
The following table presents an unranked list of financial performance measures the Compensation Committee considers to be most important in determining the compensation of the Corporation's named executive officers. As described in greater detail in the section titled "Compensation Discussion & Analysis" beginning on page 26 above, the Corporation's objective in designing its compensation program is to align executive compensation with the Corporation's long-term growth and sustained earnings objectives of the Corporation's shareholders, while attracting, retaining and motivating highly-qualified executives, and balancing both the risks and rewards of the program. Because the Corporation's compensation program generally seeks to incentivize long-term performance, the Compensation Committee does not specifically seek to align the Corporation's performance measures with Compensation Actually Paid (as defined by SEC rules) for a particular year.

FREQUENTLY ASKED QUESTIONS REGARDING THE ANNUAL MEETING

Q: Why am I receiving these materials? A: The Board of Directors of the Corporation is soliciting proxies for use at the Mid Penn Bancorp, Inc. 2026 Annual Meeting of Shareholders, which will be held in a virtual meeting format conducted exclusively by webcast on Tuesday, May 12, 2026, at 10 a.m. EDT.
Q: Why are you holding a virtual meeting instead of a physical meeting? A: The virtual meeting format allows us to leverage technology to facilitate shareholder access to the annual meeting by enabling attendance and participation from any location. Your attendance at the annual meeting via the webcast affords you the same rights and opportunities as you would have at an in-person meeting.
Q: What am I being asked to vote on? A:

At the annual meeting, shareholders of record as of March 13, 2026 (the record date) will be asked to:

(i)  elect five (5) directors to Class A for three (3) year terms expiring in 2029;

(ii)   approve a non-binding, advisoryvote regarding the compensation paid to our named executive officers as disclosed in this proxy statement; and

(iii)  ratify the selection of Deloitte & Touche LLP as the Corporation's independent registered public accounting firm for the year ending December 31, 2026.

The Board of Directors is not aware of any other matters to be presented for action at the meeting. If any other matter requiring a vote of the shareholders would be properly presented at the annual meeting, the proxies will vote according to the directions of the Board of Directors.

Q: How does the Board of Directors recommend I vote my shares? A: The Board recommends that shareholders vote FOR each of the aforementioned proposals. As of March 13, 2026, directors and executive officers of the Corporation and their affiliates had the right to vote 1,829,875 shares of Corporation common stock, or 7.2% of the outstanding Corporation common stock entitled to vote at the annual meeting.
Q: What do I need to do now? A: After carefully reading and considering the information contained in this proxy statement, please submit your proxy as soon as possible so that your shares will be represented at the annual meeting. Please follow the instructions set forth on the Notice or on the voting instruction form provided by the record holder if your shares are held in the name of your broker or other nominee.
Q: Who is entitled to vote at the annual meeting? A: Shareholders of record, sometimes referred to as a "registered shareholder," as of the close of business on March 13, 2026, which is referred to as the "record date," are entitled to notice of, and to vote at, the annual meeting.

FREQUENTLY ASKED QUESTIONS REGARDING THE ANNUAL MEETING

Q: How many votes do I have? A: Each outstanding share of common stock is entitled to one vote. Cumulative voting rights do not exist with respect to the election of directors.
Q: How do I vote my shares? A:

Shareholders of record may vote their shares by completing and returning a physical proxy card, by Internet, by telephone or by voting virtually at the annual meeting.

Voting by Mail. Shareholders of record may vote their shares by completing and returning a physical proxy card. Your proxy will be voted in accordance with your instructions. If you submit a properly executed and dated proxy, but do not specify a choice on one of the proposals described in this proxy statement, your proxy will be voted in favor of that proposal.

Voting by Internet. If you are a registered shareholder, you may vote electronically through the Internet by following the instructions included on your Notice. If your shares are registered in the name of a broker or other nominee, you may be able to vote via the Internet. If so, the voting form your nominee sends you will provide Internet instructions.

Voting by Phone. If you are a registered shareholder, you may vote by phone by calling (866) 883-0222.Remember to have your Notice or proxy card in hand when you call, and then follow the instructions.

Voting Virtually at the Annual Meeting. Shareholders of record may vote at the virtual meeting if they register at www.proxydocs.com/MPB by 12 p.m. EDT on May 11, 2026, attend the virtual meeting on May 12, 2026, at 10 a.m. EDT, and then click on the "Vote" link. Information regarding how to virtually attend the annual meeting is included below, on the Notice, and on the proxy card. If your shares are registered in the name of a broker or other nominee and you wish to vote at the meeting, you may need to obtain a legal proxy from your bank or brokerage firm. Please consult the voting form sent to you by your bank or broker to determine how to obtain a legal proxy in order to vote at the annual meeting.

Q: If my shares are held in street name by a broker, will my broker automatically vote my shares? A: If your shares are held in an account at a bank, brokerage firm, broker-dealer or other similar organization, then you are a beneficial owner of shares held in street name. In that case, you will have received proxy materials from the organization holding your account and, as a beneficial owner, you have the right to instruct your broker, bank, trustee, or nominee how to vote the shares held in your account. If no voting instructions are given, your broker or nominee has discretionary authority to vote your shares on your behalf on routine matters. A "broker non-vote" resultson a matter when your broker or nominee returns a proxy, but does not vote on a particular proposal because it does not have discretionary authority to vote on that proposal and has not received voting instructions from you. We believe that your broker or nominee only has discretionary voting power with respect to the proposal regarding the ratification of the selection of the independent registered public accounting firm. If you wish to attend and vote virtually at the annual meeting, please visit www.proxydocs.com/MPB, and follow the instructions. You may be instructed to obtain a legal proxy from your bank, broker-dealer, or other similar organization and to submit a copy in advance of the meeting. Further instructions will be provided to you via email as part of the attendance process. It is important that you instruct your broker how to vote your shares.

FREQUENTLY ASKED QUESTIONS REGARDING THE ANNUAL MEETING

Q: What constitutes a quorum for the annual meeting? A: As of the record date, 25,339,110 shares of Corporation common stock were outstanding, each of which will be entitled to one vote at the meeting. Under Mid Penn's Bylaws, the presence, in person or by proxy, of shareholders entitled to cast at least a majority of the votes that all shareholders are entitled to cast constitutes a quorum for the transaction of business at the annual meeting. If you vote by proxy, your shares will be included for determining the presence of a quorum. Abstentions are also included for determining the presence of a quorum. If you fail to submit a proxy prior to the annual meeting or to vote at the meeting, your shares will not be counted towards a quorum.
Q: Assuming the presence of a quorum, what is the vote required to approve the matters to be considered at the annual meeting? A:

The five candidates for director receiving the highest number of votes cast by shareholders, even if less than a majority, will be elected. Consequently, any shares not voted (whether by abstention, broker non-vote orotherwise) will not be included in determining which nominees received the highest number of votes. A properly executed proxy that withholds authority with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, although it will be counted for purposes of determining whether there is a quorum.

Approval of each of the other proposals will require the affirmative vote of the holders of at least a majority of the votes cast at the annual meeting. Under Pennsylvania law, abstentions are not considered "votes cast" and, accordingly, will have no effect on such other proposals.

Q: How can I attend the annual meeting? A:

The annual meeting will be a completely virtual meeting of shareholders, which will be conducted exclusively by webcast. You are entitled to participate in the annual meeting only if you were a shareholder as of the close of business on March 13, 2026, the record date. No physical meeting will be held.

In order to attend the annual meeting, you must register at www.proxydocs.com/MPBby 12 p.m. EDT on May 11, 2026. As part of the attendance process, you will be asked to provide the control number located on your proxy card or Notice. Upon completion of your registration, you will receive further instructions via email that will provide you access to the annual meeting.

The online meeting will begin promptly at 10 a.m., EDT. We encourage you to access the meeting prior to the start time leaving ample time for the check in. Please follow the registration instructions as outlined in this proxy statement.

Q: How do I register to attend the annual meeting virtually on the Internet? A:

FREQUENTLY ASKED QUESTIONS REGARDING THE ANNUAL MEETING

Q: Can I change my vote? A:

Yes. You may revoke any proxy at any time before it is voted by (1) signing and returning a proxy card with a later date (if you submitted your proxy by Internet or by telephone, you can vote again by Internet or telephone), (2) delivering a written revocation letter to the Corporate Secretary, or (3) virtually attending the annual meeting, notifying the Corporate Secretary and voting at the annual meeting. Mid Penn's Corporate Secretary's mailing address is Mid Penn Bancorp, Inc., 2407 Park Drive, Harrisburg, Pennsylvania 17110, Attention: Corporate Secretary.

Any shareholder entitled to vote virtually at the annual meeting may vote regardless of whether a proxy has been previously given, and such vote will revoke any previous proxy, but the mere virtual presence (without notifying Mid Penn's Corporate Secretary) of a shareholder at the annual meeting will not constitute revocation of a previously given proxy. A shareholder may change his or her vote up and until the time that votes are counted but not thereafter.

Q: How will proxies be solicited and who will bear the cost of soliciting votes for the annual meeting? A: The Corporation's directors, officers and Bank employees may solicit proxies in person or by telephone, facsimile, email or other similar 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 shares held by these entities. The Corporation will, upon request, reimburse these third parties for their reasonable expenses in forwarding solicitation material to the beneficial owners of shares.
Q: What if I receive more than one set of proxy materials? A: Your shares are probably registered differently or are in more than one account. Vote all proxies you receive to ensure that all your shares are voted. If you have all of your accounts registered in the same name and address, you should only receive one set of proxy materials in future years. If you are receiving multiple sets of proxy materials and wish to receive only one, please notify your broker if your shares are held in a brokerage account or our transfer agent, Computershare at (800) 368-5948, ifyou directly hold registered shares.
Q: How may I submit a question for the annual meeting? A: In order for management to thoroughly answer any questions that you may have about the Corporation or our annual meeting materials, including financial statements, we ask that you submit your questions prior to the Annual Meeting of Shareholders. You may submit questions either by mail or telephone by contacting Elizabeth O. Martin, Corporate Secretary, Mid Penn Bancorp, Inc., 2407 Park Drive, Harrisburg, Pennsylvania 17110, (866) 642-7736. Questionsreceived in advance of the meeting will be compiled by the Corporate Secretary and relayed promptly to management and the Board. Management and the Board will endeavor to address all relevant questions submitted at the meeting.
Q: When are nominations and proposals due from shareholders for the 2027 Annual Meeting? A: In order to be considered timely, you must submit your shareholder proposal or director nomination in writing by November 27, 2026, to Elizabeth O. Martin, Corporate Secretary, Mid Penn Bancorp, Inc., 2407 Park Drive, Harrisburg, Pennsylvania 17110.
