QUESTIONS AND ANSWERS ABOUT THE MERGER

The following are some questions that you may have about the merger (as defined below) and the 1st Colonial special meeting, and brief answers to those questions. We urge you to read carefully the remainder of this proxy statement/prospectus because the information in this section does not provide all of the information that might be important to you with respect to the merger or the 1st Colonial special meeting. Additional important information is also contained in the documents incorporated by reference into this proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page 96 .

What is the merger?

Mid Penn Bancorp, Inc. (“Mid Penn”) and 1st Colonial Bancorp, Inc. (“1st Colonial”) have entered into an Agreement and Plan of Merger, dated September 24, 2025 (the “merger agreement”). Under the merger agreement, 1st Colonial will merge with and into Mid Penn, with Mid Penn continuing as the surviving corporation (the “merger”). Promptly following the merger, 1st Colonial Community Bank, a New Jersey-chartered bank and wholly owned subsidiary of 1st Colonial (“1st Colonial Bank”), will merge with and into Mid Penn Bank, a Pennsylvania banking institution and wholly owned subsidiary of Mid Penn (“Mid Penn Bank”), with Mid Penn Bank continuing as the surviving bank (the “bank merger”). The boards of directors of each of Mid Penn and 1st Colonial have unanimously approved the merger agreement. A copy of the merger agreement is included in this proxy statement/prospectus as Annex A .

Subject to the terms and conditions of the merger agreement, at the effective time of the merger (the “effective time”), each share of common stock, par value $0.0 per share, of 1st Colonial (“1st Colonial common stock”) issued and outstanding immediately prior to the effective time (other than certain excluded shares as described in the merger agreement, including 1st Colonial common stock held by a holder who has properly exercised dissenters’ rights in respect of such shares) will be converted into the right to receive, at the election of the holder of such shares of 1st Colonial common stock and subject to adjustment and proration as described in the merger agreement, either (a) 0.6945 of a share of common stock, par value $1.00 per share, of Mid Penn (“Mid Penn common stock”) and cash in lieu of fractional shares (the “stock consideration”) or (b) $18.50 per share of 1st Colonial common stock (the “cash consideration” and together with the stock consideration, the “merger consideration”). Sixty percent (60%) of 1st Colonial common stock outstanding as of the effective time will be converted into the stock consideration and the remaining forty percent (40%) will be converted into the cash consideration.

Based on the stock consideration and cash consideration mix, and on the closing stock price of Mid Penn common stock of $30.31 as of September 23, 2025, the last full trading day prior to public announcement of the merger, the value of the per share merger consideration payable to holders of 1st Colonial common stock was approximately $20.03.

As a result of the foregoing, based on the number of shares of Mid Penn common stock and 1st Colonial common stock outstanding as of September 24, 2025, the date of the merger agreement, it is expected that Mid Penn shareholders will hold approximately ninety-two percent (92%), and 1st Colonial shareholders will hold approximately eight percent (8%), of the shares of the combined company outstanding immediately after the effective time.

The merger cannot be completed, unless, among other things, 1st Colonial shareholders approve and adopt the merger agreement (the “requisite 1st Colonial shareholder approval”).

Why am I receiving this proxy statement/prospectus?

We are delivering this document to you because it is a proxy statement being used by the board of directors of 1st Colonial (the “1st Colonial board of directors”) to solicit proxies of holders of 1st Colonial common stock (the “1st Colonial shareholders”) in connection with a proposal to adopt and approve the merger agreement (the “1st Colonial merger proposal”). In addition, 1st Colonial shareholders will also be asked to approve a proposal to adjourn the special meeting of 1st Colonial shareholders (the “1st Colonial special meeting”), if necessary or appropriate, to solicit additional

TABLE OF CONTENTS

proxies if there are insufficient votes at the time of the 1st Colonial special meeting to adopt and approve the 1st Colonial merger proposal or to ensure that any supplement or amendment to the accompanying proxy statement/prospectus is timely provided to 1st Colonial shareholders (the “1st Colonial adjournment proposal”).

The 1st Colonial merger proposal is being included as part of 1st Colonial’s special meeting. This document serves as the proxy statement for the 1st Colonial special meeting and describes the proposals to be presented at the 1st Colonial special meeting.

This document is also a prospectus that is being delivered to 1st Colonial shareholders because, in connection with the merger, Mid Penn will be issuing shares of Mid Penn common stock to 1st Colonial shareholders as part of the merger consideration.

This proxy statement/prospectus contains important information about the merger agreement, the merger and the other proposals being voted on at the 1st Colonial special meeting, and important information to consider in connection with an investment in Mid Penn common stock. You should read it carefully and in its entirety. The enclosed materials allow you to have your shares of 1st Colonial common stock voted by proxy without attending the 1st Colonial special meeting. Your vote is important and we encourage you to submit your proxy as soon as possible, whether or not you intend to attend the 1st Colonial special meeting.

What are 1st Colonial shareholders being asked to vote on at the 1st Colonial special meeting?

At the 1st Colonial special meeting, 1st Colonial shareholders will be asked to consider and vote on the following proposals:

•

Proposal 1: the 1st Colonial merger proposal; and

•

Proposal 2: the 1st Colonial adjournment proposal.

What will 1st Colonial shareholders receive in the merger, and how will this affect holders of Mid Penn common stock?

Pursuant to the terms and subject to the conditions set forth in the merger agreement, 1st Colonial shareholders will have the right, with respect to each of their shares of 1st Colonial common stock (other than certain excluded shares as described in the merger agreement, including 1st Colonial common stock held by a holder who has properly exercised dissenters’ rights in respect of such shares), to elect to receive, subject to certain proration, adjustment and other provisions as described in the merger agreement, either (A) 0.6945 of a share of Mid Penn common stock or (B) $18.50. Mid Penn will not issue any fractional shares of Mid Penn common stock in the merger. In lieu of the issuance of any such fractional share, Mid Penn will pay to each 1st Colonial shareholder who otherwise would be entitled to receive such fractional share an amount in cash rounded to the nearest cent without interest, equal to the product of the fractional share interest as such 1st Colonial shareholder would otherwise be entitled multiplied by $18.50. Sixty percent (60%) of 1st Colonial common stock outstanding as of the effective time will be converted into the stock consideration and the remaining forty percent (40%) will be converted into the cash consideration.

The trading price of Mid Penn common stock will continue to fluctuate until the date the merger is consummated. For further information, see the section entitled “ The Merger ― Terms of the Merger Agreement ” on page 28 .

Because of the number of shares of Mid Penn common stock being issued in the merger, the percentage ownership interest in Mid Penn represented by the existing shares of Mid Penn common stock will be diluted. Mid Penn shareholders will not receive any merger consideration and will continue to own their existing shares of Mid Penn common stock after the merger.

It is intended that the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), as described below. For further information, see “ Material United States Federal Income Tax Consequences of the Merger ” beginning on page 71 .

TABLE OF CONTENTS

Will the value of the merger consideration change between the date of this proxy statement/prospectus and the time the merger is completed?

Yes. With respect to the merger consideration, although the exchange ratio is fixed, the value of the merger consideration will fluctuate between the date of this proxy statement/prospectus and the completion of the merger based upon the market value of Mid Penn common stock. Any fluctuation in the market price of Mid Penn common stock after the date of this proxy statement/prospectus will change the value of the shares of Mid Penn common stock that Mid Penn shareholders will receive.

The common stock of Mid Penn trades on the Nasdaq Global Market under the symbol “MPB.” 1st Colonial common stock is quoted on the OTC Pink Limited Market under the symbol “FCOB.” On September 23, 2025, the last full trading day preceding the public announcement of the merger, the closing price of Mid Penn common stock was $30.31 per share and the closing price of 1st Colonial common stock was $17.32 per share. On [ ], 2025, the latest practicable trading day before the date of the accompanying proxy statement/prospectus, the closing price of Mid Penn common stock was [ ] per share and the closing price of 1st Colonial common stock was [ ] per share. The value of Mid Penn common stock at the completion of the merger could be greater than, less than or the same as the value of Mid Penn common stock on the date of this proxy statement/prospectus. We urge you to obtain current market quotations for Mid Penn.

How will the merger affect 1st Colonial equity awards?

1st Colonial equity awards will be affected as follows:

1st Colonial Options : At the effective time, each option granted by 1st Colonial to purchase shares of 1st Colonial common stock (“1st Colonial option”), whether vested or unvested, that is outstanding and unexercised immediately prior to the effective time will be cancelled and converted into the right to receive a single lump sum cash payment by Mid Penn, equal to the product of (i) the number of shares of 1st Colonial common stock subject to such 1st Colonial option immediately prior to the effective time, and (ii) the excess, if any, of (A) $18.50 over (B) the exercise price per share of such 1st Colonial option, less any applicable withholding taxes and less applicable payroll deductions; provided, however, that if the exercise price per share of any such 1st Colonial option is equal to or greater than $18.50, such 1st Colonial option will be cancelled at the effective time without any cash payment being made in respect thereof.

1st Colonial Restricted Stock Units : The merger agreement also provides that 1st Colonial will take all actions necessary, such that (i) within five (5) days prior to the closing of the merger (the “closing date”), (a) any vesting restrictions on each then outstanding restricted stock unit granted by 1st Colonial (“1st Colonial restricted stock unit”) granted under 1st Colonial’s equity compensation plans will automatically lapse, (b) each then outstanding 1st Colonial restricted stock unit will be cancelled at the time of acceleration and settled (with one share of 1st Colonial common stock being issued in settlement of each 1st Colonial restricted stock unit then being settled), provided, that the number of shares of 1st Colonial common stock issued in settlement of any 1st Colonial restricted stock unit will be net of any applicable tax withholding obligations in accordance with applicable law and (c) all accrued but unpaid dividend equivalents on the 1st Colonial restricted stock units settled pursuant to the preceding clause (b) have been paid to the holder of such 1st Colonial restricted stock unit (less all applicable withholding taxes and payroll deductions) and (ii) on the closing date, no 1st Colonial restricted stock units will be outstanding.

Does Mid Penn pay regular dividends on its shares of common stock?

Yes, Mid Penn pays quarterly cash dividends on shares of Mid Penn common stock. Mid Penn paid cash dividends on shares of Mid Penn common stock in 2024, 2023 and 2022 totaling $0.80 per share, respectively. However, declaration of future dividends is at the discretion of the board of directors of Mid Penn (the “Mid Penn board of directors”) and will depend, among other factors, on earnings, prospects, financial condition, regulatory capital levels, applicable covenants under any credit agreements and other contractual restrictions, Pennsylvania law, federal and Pennsylvania bank regulatory law. The Mid Penn board of directors makes the dividend determination quarterly.

TABLE OF CONTENTS

Who will be the directors and officers of Mid Penn and Mid Penn Bank following the merger?

At the effective time, Mid Penn will take all action necessary to appoint or elect Thomas Brugger, a current member of the 1st Colonial board of directors who was nominated by the 1st Colonial board of directors after consultation with Mid Penn, (the “1st Colonial nominee”) as a Class A director of Mid Penn and the directors of Mid Penn and Mid Penn Bank as of immediately prior to the effective time and the effective time of the bank merger (the “bank merger effective time”) will continue to serve on the Mid Penn board of directors and the board of directors of Mid Penn Bank (the “Mid Penn Bank board of directors”) following the merger and the bank merger. Mid Penn will offer all directors of 1st Colonial in office as of the effective time, other than the 1st Colonial nominee, a one-year paid advisory board position. For additional information, see the section entitled “ The Merger — Governance of Mid Penn and Mid Penn Bank Following the Merger ” beginning on page 49 .

What are the United States federal income tax consequences of the merger to 1st Colonial shareholders?

The merger has been structured to qualify as a reorganization within the meaning of Section 368(a) of the Code. It is a condition to complete the merger that each of Mid Penn and 1st Colonial receive a written opinion from their respective legal counsel to the effect that the merger will be treated as a reorganization within the meaning of Section 368(a) of the Code. Accordingly, 1st Colonial shareholders generally will only recognize gain (but not loss) in an amount not to exceed the cash (if any) received as part of the merger consideration but will recognize gain or loss (1) if such holder received the entirety of its consideration in cash or (2) with respect to any cash received in lieu of fractional shares of Mid Penn common stock. See the section entitled “ Material United States Federal Income Tax Consequences of the Merger ” beginning on page 71 .

This tax treatment may not apply to all 1st Colonial shareholders. Determining the actual tax consequences of the merger to 1st Colonial shareholders can be complicated. 1st Colonial shareholders should consult their own tax advisor for a full understanding of the merger’s tax consequences that are particular to each shareholder. For further discussion of the material United States federal income tax consequences of the merger, see the section entitled “ Material United States Federal Income Tax Consequences of the Merger ” beginning on page 71 .

Should I send in my stock certificates now?

No. Please do not send in your stock certificates with your proxy. After the merger is completed, an exchange agent selected by Mid Penn reasonably acceptable to 1st Colonial (the “exchange agent”) will send you instructions for exchanging 1st Colonial stock certificates. See the section entitled “ The Merger Agreement — Election Procedures; Exchange of Shares ” beginning on page 56 .

What should I do if I hold my shares of 1st Colonial common stock in book-entry form?

You are not required to take any additional actions if your shares of 1st Colonial common stock are held in book-entry form. You will receive separate instructions from the brokerage firm holding your shares on how to select the form of merger consideration you wish to receive (i.e., cash consideration, stock consideration, or a mix of both). Promptly following the completion of the merger, shares of 1st Colonial common stock held in book-entry form automatically will be exchanged for the merger consideration.

How does the 1st Colonial board of directors recommend that I vote at the 1st Colonial special meeting?

The 1st Colonial board of directors unanimously recommends that you vote “ FOR ” the 1st Colonial merger proposal and “ FOR ” the 1st Colonial adjournment proposal.

Who is entitled to vote at the 1st Colonial special meeting?

Effects of abstentions and broker non-votes : If you fail to vote, mark “ ABSTAIN ” on your proxy card, or fail to instruct your bank, broker or other nominee with respect to the 1st Colonial adjournment proposal, you will be deemed not to have cast a vote with respect to the 1st Colonial adjournment proposal. (assuming the presence of a quorum), however, in the absence of a quorum, abstentions will have the same effect as a vote “ AGAINST ” the adjournment proposal.

TABLE OF CONTENTS

Are there any 1st Colonial shareholders already committed to voting in favor of the 1st Colonial merger proposal?

Each of the directors and executive officers of 1st Colonial have entered into an affiliate letter with Mid Penn (the “affiliate letters”), pursuant to which each such shareholder has agreed, among other things, to vote his or her shares of 1st Colonial common stock in favor of the approval and adoption of the merger agreement, subject to the terms and conditions of the affiliate letters. As of the 1st Colonial record date, such directors and officers collectively and beneficially owned [ ]% of 1st Colonial common stock. For information regarding the affiliate letters and certain holders of shares of 1st Colonial common stock, see the section entitled “ The 1st Colonial Special Meeting — Shares Subject to 1st Colonial Affiliate Letter Agreements .”

Why is my vote important?

If you do not vote, it will be more difficult for 1st Colonial to obtain the necessary quorum to hold the 1st Colonial special meeting.

Approval of the 1st Colonial merger proposal requires the affirmative vote of at least a majority of the votes cast at the 1st Colonial special meeting. The 1st Colonial board of directors unanimously recommends that 1st Colonial shareholders vote “ FOR ” the 1st Colonial merger proposal and “ FOR ” the 1st Colonial adjournment proposal.

How can I vote my shares of 1st Colonial common stock?

1st Colonial shareholders of record may vote their 1st Colonial shares by mail, online, by phone, or in person as follows:

Voting by Mail. If you hold your shares in your name as a shareholder of record, you must complete, sign, date and mail your proxy card in the enclosed postage-paid return envelope as soon as possible. Your proxy will be voted in accordance with your instructions. If you do not specify a choice on one of the proposals described in this document, your proxy will be voted in favor of that proposal.

Voting Online. If you hold your shares in your name as a shareholder of record, you may submit your vote online by following the instructions provided on your proxy card as soon as possible.

Voting by Phone. Use any touch-tone telephone to transmit your voting instructions up until [ ] p.m. EDT the day before the cut-off date or meeting date. Have your proxy card and twelve-digit voting code in hand when you call [ ] and then follow the instructions.

At the 1st Colonial special meeting. You may virtually attend the 1st Colonial special meeting and vote. Information regarding how to virtually attend the 1st Colonial special meeting is included in the proxy card. If your shares are registered in the name of a broker or other nominee and you wish to vote at the 1st Colonial meeting, you will 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 1st Colonial special meeting.

If my shares of 1st Colonial common stock are held in “street name” by my bank or broker, will my bank or broker automatically vote my shares for me?

No. Your bank or broker cannot vote your shares without instructions from you. If your shares are held in “street name” through a bank, broker or other nominee, you must provide the record holder of your shares of 1st Colonial common stock with instructions on how to vote the shares. Please follow the voting instructions provided by the bank or broker. You may not vote shares held in street name by returning a proxy card directly to 1st Colonial, or by voting virtually at the 1st Colonial special meeting, unless you provide a “legal proxy,” which you must obtain from your broker, bank, or other nominee. Further, brokers, banks, or other nominees who hold shares of 1st Colonial common stock on behalf of their customers may not give a proxy to 1st Colonial to vote those shares with respect to any of the proposals without specific instructions from their customers, as brokers, banks, and other nominees do not have discretionary voting power on these matters.

TABLE OF CONTENTS

What is a broker “non-vote”?

Banks, brokers, trustees and other nominees who hold shares in street name for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, banks, brokers, trustees and other nominees are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine” without specific instructions from the beneficial owner.

A broker non-vote occurs when a bank, broker, trustee or other nominee is not permitted to vote on a “non-routine” matter without instructions from the beneficial owner of the shares and the beneficial owner fails to provide the bank, broker, trustee or other nominee with such instructions. Broker non-votes only count toward a quorum if at least one proposal is presented with respect to which the bank, broker, trustee or other nominee has discretionary authority. It is expected that all proposals to be voted on at the 1st Colonial special meeting will be “non-routine” matters, and, as such, broker non-votes, if any, will not be counted as present and entitled to vote for purposes of determining a quorum at the 1st Colonial special meeting. If your bank, broker, trustee or other nominee holds your shares of 1st Colonial common stock in “street name,” such entity will vote your shares of 1st Colonial common stock only if you provide instructions on how to vote by complying with the instructions provided to you by your bank, broker, trustee or other nominee with this proxy statement/prospectus.

How will proxies be solicited and who will bear the cost of soliciting votes for the 1st Colonial special meeting?

To assist in the solicitation of proxies, 1st Colonial has engaged [ ] as proxy solicitor for the 1st Colonial special meeting, for a fee of $[ ] plus reimbursement of certain costs and expenses incurred in the solicitation. The proxy for the 1st Colonial special meeting is being solicited on behalf of the 1st Colonial board of directors. 1st Colonial will bear the entire cost of soliciting proxies from you. Proxies will be solicited principally by mail, but may also be solicited by the directors, officers and other employees of 1st Colonial in person or by telephone, facsimile or other means of electronic communication. Directors, officers and employees will receive no compensation for these activities in addition to their regular compensation, but may be reimbursed for out-of-pocket expenses in connection with such solicitation.

What will happen if I return my proxy card without indicating how to vote?

If you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of 1st Colonial common stock represented by your proxy will be voted as recommended by the 1st Colonial board of directors with respect to such proposals.

Can I revoke my proxy or change my vote after I have delivered my proxy or voting instruction card?

If you directly hold shares of 1st Colonial common stock in your name as a record holder, you can change your vote at any time before your proxy is voted at your meeting. You can do this by:

•

submitting a written statement that you would like to revoke your proxy to the corporate secretary of 1st Colonial;

•

signing and returning a proxy card with a later date;

•

voting by internet as indicated on your proxy card; or

•

virtually attending the 1st Colonial special meeting and voting at the 1st Colonial special meeting.

If you are a beneficial owner and your shares are held by a bank, broker, trustee or other nominee, you may change your vote by:

•

contacting your bank, broker, trustee or other nominee; or

•

attending the 1st Colonial special meeting and voting your shares. Please contact your bank, broker, trustee or other nominee for further instructions.

TABLE OF CONTENTS

What should I do if I receive more than one set of voting materials?

1st Colonial shareholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold shares of 1st Colonial common stock in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold such shares. If you are a holder of record of 1st Colonial common stock and your shares are registered in more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive or otherwise follow the voting instructions set forth in this proxy statement/prospectus to ensure that you vote every share of 1st Colonial common stock that you own.

Are 1st Colonial shareholders entitled to appraisal rights?

Yes. 1st Colonial shareholders will be entitled to dissenters’ rights with respect to the merger, entitling them to request the “fair value” of their shares of 1st Colonial common stock. For more information, see the section entitled “ Appraisal Rights ” and Annex C attached to this proxy statement/prospectus.

Are there any risks that I should consider in deciding whether to vote for the adoption and approval of the 1st Colonial merger proposal or the other proposals to be considered at the 1st Colonial special meeting?

Yes. You should read and carefully consider the risk factors set forth in the section entitled “ Risk Factors ” beginning on page 21 . You also should read and carefully consider the risk factors of Mid Penn contained in the documents that are incorporated by reference into this proxy statement/prospectus.

When is the merger expected to be completed?

Neither Mid Penn nor 1st Colonial can predict the actual date on which the merger will be completed, or if the merger will be completed at all, because completion is subject to conditions and factors outside the control of both companies. Subject to the satisfaction or waiver of the closing conditions as contemplated by the merger agreement, including approval of the merger agreement by the 1st Colonial shareholders by the requisite 1st Colonial shareholder vote and the receipt of all requisite regulatory approvals, we currently expect to complete the merger late in the first quarter or early in the second quarter of 2026. It is possible, however, that the transaction may not be completed when expected or at all because required regulatory, shareholder or other approvals or conditions to closing are not received or satisfied on a timely basis.

What happens if the merger is not completed?

If the merger is not completed, 1st Colonial shareholders will not receive any consideration for their shares of 1st Colonial common stock in connection with the merger. Instead, 1st Colonial will remain an independent company and its common stock will continue to be quoted on the OTC Pink Limited Market. Under specified circumstances, 1st Colonial may be required to pay to Mid Penn a fee with respect to the termination of the merger agreement. For more information, please review the sections entitled “ The Merger Agreement — Termination of the Merger Agreement ” beginning on page 69 and “ The Merger Agreement — Termination Fee ” beginning on page 70 .

To make an election, a 1st Colonial shareholder holder must submit a properly completed election form and return it so that the form is actually received at or before the election deadline in accordance with the instructions on the election form.

Non-Electing 1st Colonial Shareholders (page 54 )

1st Colonial shareholders who make no election to receive the cash consideration or stock consideration in the merger or who do not make a valid election (the “non-election shares”) will be deemed to have elected either stock consideration or cash consideration depending on the proration adjustments required by the merger agreement (discussed below).

Proration (page 54 )

The total number of shares of 1st Colonial common stock (including shares of 1st Colonial common stock issued prior to the effective time for exercises of 1st Colonial options and vesting of 1st Colonial restricted stock units) entitled to receive the stock consideration will be equal to sixty percent (60%) of the number of shares of 1st Colonial common stock outstanding immediately prior to the effective time. Similarly, the total number of shares of 1st Colonial common stock (including restricted stock) to be entitled to receive the cash consideration will be equal to forty percent (40%) of the number of shares of 1st Colonial common stock outstanding immediately prior to the effective time.

To achieve this, if the aggregate number of shares of 1st Colonial common stock with respect to which an election to receive the cash consideration (the “cash election shares”) exceeds forty percent (40%) of all issued and outstanding shares of 1st Colonial immediately prior to the effective time, proration mechanisms will be applied to each 1st Colonial shareholder electing the form of merger consideration that is over-elected so that the cash election shares and the stock election shares equal sixty-forty (60 – 40). The non-election shares factor into the proration formula and will receive the form of merger consideration that is under-elected so that the cash election shares equal forty percent (40%) of the aggregate number of shares of 1st Colonial common stock immediately prior to the effective time and the stock election shares equal sixty percent (60%) of the aggregate number of shares of 1st Colonial common stock immediately prior to the effective time. The specifics of the proration adjustments are described herein at “ The Merger Agreement ― Consideration to Be Received in the Merger ― Proration ”.

TABLE OF CONTENTS

common stock subject to such 1st Colonial option immediately prior to the effective time, and (ii) the excess, if any, of (A) $18.50 over (B) the exercise price per share of such 1st Colonial option, less any applicable withholding taxes and less applicable payroll deductions; provided, however, that if the exercise price per share of any such 1st Colonial option is equal to or greater than $18.50, such 1st Colonial option will be cancelled at the effective time without any cash payment being made in respect thereof.

1st Colonial Restricted Stock Units

The merger agreement also provides that 1st Colonial will take all actions necessary, such that (i) within five (5) days prior to the closing date, (a) any vesting restrictions on each then outstanding 1st Colonial restricted stock units granted under 1st Colonial’s equity compensation plans will automatically lapse, (b) each then outstanding 1st Colonial restricted stock unit will be cancelled at the time of acceleration and settled (with one share of 1st Colonial common stock being issued in settlement of each 1st Colonial restricted stock unit then being settled), provided, that the number of shares of 1st Colonial common stock issued in settlement of any 1st Colonial restricted stock unit will be net of any applicable tax withholding obligations in accordance with applicable law and (c) all accrued but unpaid dividend equivalents on the 1st Colonial restricted stock units settled pursuant to the preceding clause (b) have been paid to the holder of such 1st Colonial restricted stock unit (less all applicable withholding taxes and payroll deductions) and (ii) on the closing date, no 1st Colonial restricted stock units will be outstanding.

Expected Material United States Federal Income Tax Treatment as a Result of the Merger (page 71 )

The merger is structured to be treated as a reorganization within the meaning of Section 368(a) of the Code. for United States federal income tax purposes. Each of Mid Penn and 1st Colonial has conditioned the consummation of the merger on its receipt of a legal opinion that this will be the case. As such, 1st Colonial shareholders generally will only recognize gain (but not loss) in an amount not to exceed the cash (if any) received as part of the merger consideration but will recognize gain or loss (A) if such holder received the entirety of its consideration in cash or (B) with respect to any cash received in lieu of fractional shares of Mid Penn common stock.

This tax treatment may not apply to all 1st Colonial shareholders. Determining the actual tax consequences of the merger to 1st Colonial shareholders can be complicated. 1st Colonial shareholders should consult their own tax advisor for a full understanding of the merger’s tax consequences that are particular to each shareholder. For further information, please refer to the section entitled “ Material United States Federal Income Tax Consequences of the Merger ” on page 71 .

Interests of Certain 1st Colonial Directors and Executive Officers in the Merger (page 49 )

The directors and executive officers of 1st Colonial have interests in the merger that differ from, or are in addition to, the interests of 1st Colonial shareholders. These interests include, among other things, the following:

Regulatory Approvals (page 50 )

Subject to the terms of the merger agreement, both Mid Penn and 1st Colonial have agreed to use their commercially reasonable efforts and cooperate to promptly prepare and file all necessary documentation to obtain as promptly as practicable all regulatory approvals necessary or advisable to complete the transactions contemplated by the merger agreement. These include approvals from, among others, the Federal Reserve Board, the FDIC, the PDB and the NJDB. The initial filing of these regulatory applications occurred on November 24, 2025. Additional notifications and/or applications requesting approval may be submitted to various other federal, state, and non-U.S. regulatory authorities and self-regulatory organizations.

TABLE OF CONTENTS

Although neither Mid Penn nor 1st Colonial knows of any reason why it cannot obtain these regulatory approvals in a timely manner, Mid Penn and 1st Colonial cannot be certain when or if they will be obtained, or that the granting of these regulatory approvals will not involve the imposition of conditions on the completion of the merger or the bank merger.

Expected Timing of the Merger

Neither Mid Penn nor 1st Colonial can predict the actual date on which the merger will be completed, or if the merger will be completed at all, because completion is subject to conditions and factors outside the control of both companies. 1st Colonial must first obtain the requisite 1st Colonial shareholder approval and Mid Penn and 1st Colonial must also obtain the requisite regulatory approvals and satisfy certain other closing conditions. Mid Penn and 1st Colonial expect the merger to be completed once 1st Colonial has obtained the requisite 1st Colonial shareholder approval, the requisite regulatory approvals have been obtained and other closing conditions are satisfied.

Record Date . The record date for the 1st Colonial special meeting is [ ], 2025. All 1st Colonial shareholders who held shares of 1st Colonial common stock at the close of business on the 1st Colonial record date are entitled to receive notice of, and to vote at, the 1st Colonial special meeting.

Required Vote.

1st Colonial Merger Proposal. Approval of the 1st Colonial merger proposal requires the affirmative vote of at least a majority of the votes cast at the 1st Colonial special meeting. Abstentions and broker “non-votes” will have no effect on the 1st Colonial merger proposal.

1st Colonial Adjournment Proposal. The 1st Colonial adjournment proposal requires the affirmative vote of at least a majority of the votes cast at the 1st Colonial special meeting; provided that, in the absence of a quorum, a majority of 1st Colonial shareholders present in person or by proxy and entitled to vote is required for the adjournment proposal. Abstentions and broker “non-votes” will have no effect with respect to the vote on the 1st Colonial adjournment proposal (assuming the presence of a quorum), however, in the absence of a quorum, abstentions will have the same effect as a vote “ AGAINST ” the adjournment proposal.

Each of the directors and executive officers of 1st Colonial entered into an affiliate letter with Mid Penn, pursuant to which each such shareholder has agreed, among other things, to vote his or her shares of 1st Colonial common stock in favor of the approval and adoption of the merger agreement, subject to the terms of the affiliate letter.

Appraisal Rights (page 91 and Annex C)

1st Colonial shareholders have the right under Pennsylvania law to dissent from the merger agreement and obtain the “fair value” of their shares in cash as determined by an appraisal process in accordance with the procedures under Subchapter D of Chapter 15 of the Pennsylvania Business Corporation Law of 1988, as amended (“PBCL”). The statutorily determined “fair value” could be more or less than the value of the merger consideration. If you intend to exercise dissenters’ rights, you should read the statute carefully and consult with your own legal counsel. Failure to strictly comply with the procedures set forth in the PBCL will result in the loss of dissenters’ rights. Also, if you exercise dissenters’ rights, you may have taxable income as a result, so you should consult with your own tax advisor if you intend to dissent. See the section entitled “ Appraisal Rights ” on page 91 and Annex C .

The information presented above solely illustrates the implied value of the merger consideration based on the share price of Mid Penn common stock on the dates set forth above.

The market prices of Mid Penn common stock and 1st Colonial common stock have fluctuated since the date of the announcement of the merger agreement, and will continue to fluctuate from the date of this proxy statement/prospectus to the date of the 1st Colonial special meeting and the date the merger is completed and thereafter.

The number of shares of Mid Penn common stock that 1st Colonial shareholders will receive as consideration per share of 1st Colonial common stock in the merger is fixed and will not change.

The value of the shares of Mid Penn common stock to be received in exchange for each share of 1st Colonial common stock, when received by 1st Colonial shareholders after the merger is completed, could be greater than, less than or the same as shown in the table above. Accordingly, 1st Colonial shareholders are advised to obtain current market quotations for Mid Penn common stock and 1st Colonial common stock in determining whether to vote in favor of the proposals at the 1st Colonial special meeting.

Dividend Information

Dividends from Mid Penn Bank are Mid Penn’s primary source of funds to pay dividends on its common stock. Any further dividends paid on Mid Penn’s common stock would be declared and paid at the discretion of its board of directors and would be dependent upon Mid Penn’s liquidity, financial condition, results of operations, capital requirements and such other factors as the Mid Penn board of directors may deem relevant.

1st Colonial has not paid a cash dividend since its inception in June 2000.

TABLE OF CONTENTS

RISK FACTORS

In addition to general investment risks and the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the section entitled “Cautionary Statement Regarding Forward-Looking Statements,” you should carefully consider the following risk factors in deciding how to vote for the proposals presented in this proxy statement/prospectus. You should also read and consider the risk factors relating to the business of Mid Penn and ownership of Mid Penn common stock described in Part I, Item 1A of Mid Penn’s Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 13, 2025 , as well as any subsequent documents filed by Mid Penn with the SEC, which are incorporated by reference into this proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page 96 .

Risks Relating to the Consummation of the Merger and Mid Penn Following the Merger

Because the market price of Mid Penn common stock may fluctuate prior to the effective time, including as a result of 1st Colonial’s financial performance prior to the effective time, shareholders cannot be certain of the market value of the merger consideration to be received by 1st Colonial shareholders.

At the effective time of the merger, each share of 1st Colonial common stock issued and outstanding at the effective time of the merger (other than certain excluded shares as described in the merger agreement, including 1st Colonial common stock held by a holder who has properly exercised dissenters’ rights in respect of such shares) will be converted into the right to elect to receive, subject to adjustment and proration, the cash consideration or the stock consideration. This exchange ratio is fixed and will not be adjusted for changes in the market price of either Mid Penn common stock or 1st Colonial common stock. Changes in the price of Mid Penn common stock between now and the effective time will affect the value that 1st Colonial shareholders will receive in the merger. Neither Mid Penn nor 1st Colonial is permitted to terminate the merger agreement as a result of any increase or decrease in the market price of Mid Penn common stock or 1st Colonial common stock.

Stock price changes may result from a variety of factors, including general market and economic conditions, changes in Mid Penn’s and 1st Colonial’s businesses, operations and prospects, the performance of peer companies and other financial companies, volatility in the prices of securities in global financial markets, including market prices of Mid Penn, 1st Colonial and other banking companies, the effects of proposed or imposed tariffs by the U.S. government and retaliatory tariffs proposed or imposed by U.S. trading partners and the risk of any recession or slowdown in economic growth, particularly in the states of New Jersey and Pennsylvania, and regulatory considerations and tax laws, many of which are beyond Mid Penn’s and 1st Colonial’s control. Therefore, at the time of the 1st Colonial special meeting, 1st Colonial shareholders will not know the market value of the merger consideration that 1st Colonial shareholders will receive at the effective time. You should obtain current market quotations for shares of Mid Penn common stock (Nasdaq trading symbol MPB).

1st Colonial shareholders may receive a form of consideration different from what they elect.

While each 1st Colonial shareholder may elect to receive the cash consideration, the stock consideration or a mix of both, sixty percent (60%) of the 1st Colonial stock outstanding at the completion of the merger will be converted into the stock consideration and forty percent (40%) will be converted into the cash consideration. Therefore, if 1st Colonial shareholders elect more cash or stock than is available under the merger agreement, their elections will be prorated so that sixty percent (60%) of the 1st Colonial common stock outstanding at the completion of the merger is converted into the stock consideration and the remaining forty percent (40%) is converted into the cash consideration. As a result, a 1st Colonial shareholder’s ability to receive cash or stock in accordance with their election may depend on the election of other 1st Colonial shareholders.

Because 1st Colonial common stock is traded infrequently and is listed on OTC Pink Limited Market, it is difficult to determine how the market value of 1st Colonial common stock compares with the merger consideration.

1st Colonial’s common stock is listed on OTC Pink Limited Market, a decentralized market where securities not listed on major exchanges are traded directly by a network of dealers. Instead of providing an

TABLE OF CONTENTS

order matchmaking service, these dealers carry inventories of securities in order to facilitate any buy and sell orders. Because OTC Pink Limited Market is a thinly traded market and lacks the liquidity of certain other public markets with which some investors may have more experience, investors may have difficulty determining how the market value of 1st Colonial compares with the merger consideration.

The market price of Mid Penn common stock after the merger may be affected by factors different from those currently affecting the independent businesses of Mid Penn and 1st Colonial.

As a result of the merger, 1st Colonial shareholders will become Mid Penn shareholders. Mid Penn’s business differs from that of 1st Colonial and certain adjustments may be made to Mid Penn’s business as a result of the merger. Accordingly, the results of operations of Mid Penn and the market price of Mid Penn common stock after the completion of the merger may be affected by factors different from those currently affecting the independent results of operations of each of Mid Penn and 1st Colonial. For a discussion of the businesses of Mid Penn and 1st Colonial and of certain factors to consider in connection with those businesses, see the documents incorporated by reference in this proxy statement/prospectus and referred to under the section entitled “ Where You Can Find More Information .”

The opinion delivered by Stephens to the 1st Colonial board of directors prior to the entry into the merger agreement will not reflect changes in circumstances that may have occurred since the date of such opinion.

The opinion of Stephens, 1st Colonial’s financial advisor, to the 1st Colonial board of directors, was delivered on and dated September 24, 2025. Changes in the operations and prospects of 1st Colonial, general market and economic conditions and other factors which may be beyond the control of 1st Colonial, including the ongoing effects of proposed or imposed tariffs by the U.S. government and retaliatory tariffs proposed or imposed by U.S. trading partners and the risk of any recession or slowdown in economic growth, particularly in New Jersey and Pennsylvania, on such market and economic conditions, and the market prices of 1st Colonial common stock, may have altered the value of 1st Colonial or the share price of 1st Colonial common stock as of the date of this proxy statement/prospectus, or may alter such values and prices by the effective time. The opinion does not speak as of the date of this proxy statement/prospectus or as of any other date subsequent to the date of such opinion.

Regulatory approvals may not be received, may take longer than expected, or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the merger.

Before the merger and the bank merger may be completed, various approvals, consents and non-objections must be obtained from the Federal Reserve Board, the FDIC, the PDB and the NJDB and other regulatory authorities in the United States. In determining whether to grant these approvals, such regulatory authorities consider a variety of factors, including the regulatory standing of each party. These approvals could be delayed or not obtained at all, including due to an adverse development in either party’s regulatory standing or in any other factors considered by regulators when granting such approvals; governmental, political, or community group inquiries, investigations, or opposition; or changes in legislation or the political environment generally.

The approvals that are granted may impose terms and conditions, limitations, obligations, or costs, or place restrictions on the conduct of the combined company’s business or require changes to the terms of the transactions contemplated by the merger agreement. There can be no assurance that regulators will not impose any such conditions, limitations, obligations, or restrictions and that such conditions, limitations, obligations, or restrictions will not have the effect of delaying the completion of any of the transactions contemplated by the merger agreement, imposing additional material costs on or materially limiting the revenues of the combined company following the merger or otherwise reducing the anticipated benefits of the merger if the merger was consummated successfully within the expected timeframe. In addition, there can be no assurance that any such conditions, terms, obligations, or restrictions will not result in the delay or abandonment of the merger. Additionally, the merger is conditioned on the absence of any order, injunction or decree that enjoins or prohibits consummation of the transactions contemplated by the merger agreement.

Mid Penn and 1st Colonial are expected to incur substantial costs related to the merger and integration, and these costs may be greater than anticipated due to unexpected events.

Mid Penn and 1st Colonial have incurred and expect to incur a number of significant non-recurring costs associated with the merger. These costs include legal, financial advisory, accounting, consulting and

TABLE OF CONTENTS

other advisory fees, severance/employee benefit-related costs, public company filing fees and other regulatory fees, financial printing and other printing costs and other related costs. Some of these costs are payable by either Mid Penn or 1st Colonial regardless of whether or not the merger is completed.

In addition, Mid Penn will incur integration costs following the completion of the merger as Mid Penn and 1st Colonial integrate their businesses, including facilities and systems consolidation costs and employment-related costs. Mid Penn and 1st Colonial may also incur additional costs to maintain employee morale and to retain key employees. There are a large number of processes, policies, procedures, operations, technologies and systems that may need to be integrated, including purchasing, accounting and finance, payroll, compliance, treasury management, branch operations, vendor management, risk management, lines of business, pricing and benefits. While Mid Penn and 1st Colonial have assumed that a certain level of costs will be incurred, there are many factors beyond their control that could affect the total amount or the timing of the integration costs. Moreover, many of the costs that will be incurred are, by their nature, difficult to estimate accurately. These integration costs may result in Mid Penn taking charges against earnings following the completion of the merger, and the amount and timing of such charges are uncertain at present. There can be no assurances that the expected benefits and efficiencies related to the integration of the businesses will be realized to offset these transaction and integration costs over time.

Combining Mid Penn and 1st Colonial may be more difficult, costly or time-consuming than expected, and Mid Penn and 1st Colonial may fail to realize the anticipated benefits and cost savings of the merger.

The success of the merger will depend, in part, on the ability to realize the anticipated cost savings from combining the businesses of Mid Penn and 1st Colonial. To realize the anticipated benefits and cost savings from the merger, Mid Penn and 1st Colonial must successfully integrate and combine their businesses in a manner that permits those cost savings to be realized without adversely affecting current revenues and future growth. If Mid Penn and 1st Colonial are not able to successfully achieve these objectives, the anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected. In addition, the actual cost savings of the merger could be less than anticipated, and integration may result in additional and unforeseen expenses.

An inability to realize the full extent of the anticipated benefits of the merger and the other transactions contemplated by the merger agreement, as well as any delays encountered in the integration process, could have an adverse effect upon the revenues, levels of expenses and operating results of Mid Penn following the completion of the merger, which may adversely affect the value of the common stock of Mid Penn following the completion of the merger.

Mid Penn and 1st Colonial have operated and, until the effective time, must continue to operate, independently. It is possible that the integration process could result in the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the companies’ ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits and cost savings of the merger. Integration efforts between the companies may also divert management attention and resources. These integration matters could have an adverse effect on each of Mid Penn and 1st Colonial during this transition period and for an undetermined period after completion of the merger on Mid Penn.

The future results of Mid Penn following the completion of the merger may suffer if Mid Penn does not effectively manage its expanded operations.

Following the merger, the size of the business of Mid Penn will increase beyond the current size of either Mid Penn’s or 1st Colonial’s business. Mid Penn’s future success will depend, in part, upon its ability to manage this expanded business, which may pose challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. Mid Penn may also face increased scrutiny from governmental entities as a result of the increased size of its business. There can be no assurances that Mid Penn will be successful or that it will realize the expected operating efficiencies, revenue enhancement or other benefits currently anticipated from the merger.

Mid Penn may be unable to retain legacy 1st Colonial personnel successfully after the completion of the merger.

The success of the merger will depend in part on Mid Penn’s ability to retain the talent and dedication of key employees currently employed by 1st Colonial. It is possible that these employees may decide not to

TABLE OF CONTENTS

remain with 1st Colonial while the merger is pending or after the completion of the merger. If Mid Penn and 1st Colonial are unable to retain key employees, including management, who are critical to the successful integration and future operations of Mid Penn following the merger, Mid Penn and 1st Colonial could face disruptions in their operations, loss of existing customers, loss of key information, expertise or know-how and unanticipated additional recruitment costs. In addition, following the completion of the merger, if key employees terminate their employment, Mid Penn’s business activities following the merger may be adversely affected, and management’s attention may be diverted from successfully hiring suitable replacements, all of which may cause Mid Penn’s business following the merger to suffer. Mid Penn and 1st Colonial also may not be able to locate or retain suitable replacements for key employees who leave either company.

The prospective financial information presented in this proxy statement/prospectus is based on various assumptions and may not be realized.

While presented with numeric specificity, there can be no assurance that the prospective financial information presented in this proxy statement/prospectus will be realized, and actual results may vary materially from those shown in the prospective financial information. In addition, since the prospective financial information covers multiple years, such information by its nature becomes subject to greater uncertainty with each successive year. The prospective financial information and the assumptions underlying the prospective financial information reflect numerous estimates and assumptions with respect to, among other things, economic, competitive, regulatory and financial market conditions and future business decisions that may not be realized and that are inherently subject to significant business, economic, competitive and regulatory uncertainties and contingencies, including, among other things, the inherent uncertainty of the business and economic conditions affecting the industry in which Mid Penn and 1st Colonial operate. For more information, see the section entitled “ The Merger — Certain Unaudited Prospective Financial Information ” beginning on page 44 .

Certain of 1st Colonial’s directors and executive officers may have interests in the merger that may differ from, or are in addition to, the interests of 1st Colonial shareholders.

1st Colonial shareholders should be aware that some of 1st Colonial’s directors and executive officers may have interests in the merger and have arrangements that are different from, or in addition to, those of 1st Colonial shareholders. These interests and arrangements may create potential conflicts of interest. The 1st Colonial board of directors was aware of these respective interests and arrangements and considered these interests and arrangements, among other matters, when making their decisions to adopt and approve the merger agreement, and in recommending that 1st Colonial shareholders vote to adopt and approve the 1st Colonial merger proposal and the 1st Colonial adjournment proposal. For more information, see the section entitled, “ Interests of Certain 1st Colonial Directors and Executive Officers in the Merger ” beginning on page 45 .

If the requisite 1st Colonial shareholder approval is not obtained, or other conditions to the closing of the merger are not met, the merger agreement may be terminated in accordance with its terms and the merger may not be completed.

The merger agreement is subject to a number of conditions which must be fulfilled in order to complete the merger. Those conditions include (i) the receipt of the 1st Colonial shareholder approval; (ii) the filing of a notification of listing of the shares of Mid Penn common stock to be issued in the merger with Nasdaq and non-objection by Nasdaq to such listing; (iii) the receipt of required regulatory approvals, including the approval of the Federal Reserve Board, the FDIC, the PDB and the NJDB; without the imposition of any condition or requirement, excluding standard conditions that are normally imposed by the regulatory authorities in bank merger transactions, that would, in the good faith reasonable judgment of the board of directors of either Mid Penn or 1st Colonial, materially and adversely affect the business, operations, financial condition, property or assets of the combined enterprise or materially impair the value of 1st Colonial to Mid Penn or the value of Mid Penn to 1st Colonial; (iv) the effectiveness of the registration statement on Form S-4 relating to the shares of Mid Penn common stock to be issued in the merger and no stop order, or related proceedings, suspending the effectiveness of the registration statement on Form S-4 will have been initiated or threatened; and (v) the absence of any order, injunction or decree prohibiting or making illegal the consummation of the merger. Each party’s obligation to complete the merger is also subject to certain additional customary conditions, including (1) subject to certain exceptions, the accuracy of the

TABLE OF CONTENTS

representations and warranties of the other party, (2) performance in all material respects by the other party of its obligations under the merger agreement, (3) receipt by such party of an opinion from its counsel to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code and (4) the absence of a material adverse effect with respect to the other party since the execution of the merger agreement. Mid Penn’s obligation to complete the merger is also subject to the condition that holders of not more than five percent (5%) of the outstanding shares of 1st Colonial common stock have properly exercised their dissenters’ rights under Pennsylvania law.

These conditions to the closing of the merger may not be fulfilled in a timely manner or at all, and, accordingly, the merger may not be completed. In addition, the parties can mutually decide to terminate the merger agreement at any time, before or after the requisite 1st Colonial shareholder approval, or Mid Penn or 1st Colonial may elect to terminate the merger agreement in certain other circumstances.

Each of the officers and directors of 1st Colonial have executed an affiliate letter that requires each such shareholder to vote in favor of the approval and adoption of the merger agreement.

Each of the officers and directors of 1st Colonial have entered into an affiliate letter with Mid Penn. Pursuant to the affiliate letters, each such shareholder has agreed, among other things, to vote his or her shares of 1st Colonial common stock in favor of the approval and adoption of the merger agreement, and against any action or agreement that would reasonably be expected to prevent, impede, or delay the consummation of the merger. As of the 1st Colonial record date, these shareholders collectively and beneficially owned approximately [ ]% of the outstanding shares of 1st Colonial common stock. See the section entitled “ The 1st Colonial Special Meeting — Shares Subject to 1st Colonial Affiliate Letters Agreements ” beginning on page 80 and “ Beneficial Ownership of 1st Colonial Common Stock by Management, Directors and Principal Shareholders of 1st Colonial. ”

Failure to complete the merger could negatively impact Mid Penn or 1st Colonial.

If the merger is not completed for any reason, including as a result of 1st Colonial shareholders’ failure to approve and adopt the 1st Colonial merger proposal, there may be various adverse consequences and Mid Penn and/or 1st Colonial may experience negative reactions from the financial markets and from their respective customers and employees. For example, Mid Penn’s or 1st Colonial’s respective businesses may be adversely impacted by the failure to pursue other beneficial opportunities due to the focus of management on the merger, without realizing any of the anticipated benefits of completing the merger. Additionally, if the merger agreement is terminated, the market price of Mid Penn common stock or 1st Colonial common stock could decline to the extent that current market prices reflect a market assumption that the merger will be beneficial and will be completed. If the merger agreement is terminated under certain circumstances, 1st Colonial may be required to pay a termination fee of $4,040,000 million to Mid Penn.

Additionally, each of Mid Penn and 1st Colonial has incurred and will incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the merger agreement, as well as the costs and expenses of preparing, filing, printing and mailing this proxy statement/ prospectus, and all filing and other fees paid in connection with the merger. If the merger is not completed, Mid Penn and 1st Colonial would have to pay some of these expenses without realizing the expected benefits of the merger.

Mid Penn and 1st Colonial will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Mid Penn and 1st Colonial. These uncertainties may impair Mid Penn’s or 1st Colonial’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with Mid Penn or 1st Colonial to seek to change existing business relationships with Mid Penn or 1st Colonial. In addition, subject to certain exceptions, Mid Penn and 1st Colonial have each agreed to operate its business only in the usual, regular and ordinary course in all material respects and to refrain from taking certain actions that may adversely affect or delay its ability to consummate the transactions contemplated by the merger agreement on a timely basis without the consent of the other party. These restrictions may prevent Mid Penn and/or 1st Colonial from pursuing attractive business opportunities that may arise prior to the completion of the merger.

TABLE OF CONTENTS

The announcement of the proposed merger could disrupt Mid Penn’s and 1st Colonial’s relationships with their employees, customers, suppliers, business partners and others, as well as their operating results and business generally.

Whether or not the merger is ultimately consummated, as a result of uncertainty related to the proposed transaction, risks relating to the impact of the announcement of the merger on Mid Penn’s and 1st Colonial’s business include the following:

•

their employees may experience uncertainty about their future roles, which might adversely affect Mid Penn’s and 1st Colonial’s ability to retain and hire key personnel and other employees;

•

customers, suppliers, business partners and other parties with which Mid Penn and 1st Colonial maintain business relationships may experience uncertainty about their future and seek alternative relationships with third parties, seek to alter their business relationships with Mid Penn and 1st Colonial or fail to extend existing relationships with Mid Penn and 1st Colonial; and

•

Mid Penn and 1st Colonial have each expended and will continue to expend significant costs, fees and expenses for professional services and transaction costs in connection with the proposed merger.

If any of the aforementioned risks were to materialize, they could lead to significant costs which may impact each party’s results of operations and financial condition.

The merger agreement limits 1st Colonial’s ability to pursue alternatives to the merger.

The merger agreement contains “no shop” covenants that, subject to specified exceptions, restrict 1st Colonial’s ability to, directly or indirectly, among other things, initiate, solicit, induce or encourage or take any action to facilitate the making of, any inquiry, offer or proposal which constitutes or could reasonably be expected to lead to an acquisition proposal. These provisions, which could result in a $4,040,000 termination fee payable under certain circumstances, may discourage a potential third-party acquirer that might have an interest in acquiring all or a significant part of 1st Colonial from considering or making that acquisition proposal, even if it were prepared to pay consideration with a higher per share value than that proposed in the merger, or might result in a potential competing acquiror proposing to pay a lower per share price to acquire 1st Colonial than it might otherwise have proposed to pay, if the merger with Mid Penn had not been announced.

The shares of Mid Penn common stock to be received by 1st Colonial shareholders as a result of the merger will have different rights from the shares of 1st Colonial common stock.

Upon completion of the merger, the rights of former 1st Colonial shareholders who receive shares of Mid Penn common stock in the merger and thereby become Mid Penn shareholders will be governed by the Mid Penn articles and the Mid Penn bylaws. The rights associated with 1st Colonial common stock are different from the rights associated with Mid Penn common stock. See the section entitled “ Comparison Shareholders Rights .”

Mid Penn has various provisions in the Mid Penn articles and Mid Penn bylaws that could impede a takeover of Mid Penn.

The Mid Penn articles and Mid Penn bylaws contain provisions providing for, among other things, a supermajority vote requirement for mergers, the staggered election of Mid Penn’s board of directors, and the absence of cumulative voting. Although these provisions were not adopted for the express purpose of preventing or impeding the takeover of Mid Penn, without the approval of the Mid Penn board of directors, such provisions may have that effect. Such provisions may prevent former 1st Colonial shareholders who receive shares of Mid Penn common stock in the merger from taking part in a future transaction in which such shareholders could realize a premium over the current market price of Mid Penn common stock.

1st Colonial shareholders will have a reduced ownership and voting interest in Mid Penn after the consummation of the merger and will exercise less influence over management.

1st Colonial shareholders currently have the right to vote in the election of the board of directors and on other matters affecting 1st Colonial. When the merger is completed, each 1st Colonial shareholder will become a Mid Penn shareholder, with a percentage ownership of the shares of common stock of Mid Penn that is smaller than the holder’s percentage ownership of 1st Colonial prior to the consummation of the

TABLE OF CONTENTS

merger. Based on the number of shares of Mid Penn common stock outstanding as of September 24, 2025, the date of the merger agreement, and based on the number of shares of Mid Penn common stock expected to be issued in the merger, we estimate that existing Mid Penn shareholders will own approximately ninety-two percent (92%) and former 1st Colonial shareholders will own approximately eight percent (8%) of the common stock of Mid Penn following the completion of the merger. Because of this, 1st Colonial shareholders may have less influence on the management and policies of Mid Penn than they now have on the management and policies of 1st Colonial.

1st Colonial shareholders have appraisal rights in the merger.

If the merger agreement is adopted and approved by 1st Colonial shareholders, 1st Colonial shareholders who do not vote in favor of the adoption and approval of the merger agreement have the right under Pennsylvania law to dissent from the merger agreement and obtain the “fair value” of their shares in cash as determined by an appraisal process in accordance with the procedures under Subchapter D of Chapter 15 of the PBCL. In addition, under the terms of the merger agreement, if more than five percent (5%) of the aggregate outstanding shares of 1st Colonial common stock have properly notified Mid Penn of their intent to exercise appraisal rights under applicable law, then Mid Penn will not be obligated to complete the merger. Neither 1st Colonial nor Mid Penn can predict the number of 1st Colonial shareholders who will seek payment of cash fair value of their shares. See the section entitled “ Appraisal Rights .”

Issuance of shares of Mid Penn common stock in connection with the merger may adversely affect the market price of Mid Penn common stock.

Pursuant to the merger agreement, 1st Colonial shareholders may elect to receive either the cash consideration or the stock consideration. The dilution that may be caused by the issuance of new shares of Mid Penn common stock to 1st Colonial shareholders in connection with the payment of the stock consideration may result in fluctuations in the market price of Mid Penn common stock, including a Mid Penn common stock price decrease. In addition, if former 1st Colonial shareholders sell substantial amounts of the combined company’s common stock in the public market following consummation of the merger, this could decrease the market price of the combined company’s common stock.

Mid Penn or 1st Colonial or both may be subject to claims and litigation pertaining to the merger that could prevent or delay the completion of the merger.

Any lawsuits filed in connection with the merger could prevent or delay completion of the merger and result in additional costs to Mid Penn and 1st Colonial, including any costs associated with indemnification. The defense or settlement of any lawsuit or claim that may be filed seeking remedies against 1st Colonial, the 1st Colonial board of directors or Mid Penn or the Mid Penn board of directors in connection with the merger that remains unresolved at the effective time of the merger may adversely affect Mid Penn’s business, financial condition, results of operations and cash flows. There has not been any litigation against Mid Penn, 1st Colonial or the directors or officers of either company, but such litigation could be instigated.

Risks Relating to Mid Penn’s Business

You should read and consider risk factors specific to Mid Penn’s business that will also affect Mid Penn after the merger. These risks are described in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of Mid Penn’s Annual Report on Form 10-K for the year ended December 31, 2024 and in any updates to those risk factors set forth in Mid Penn’s Quarterly Reports on Form 10-Q and in other documents incorporated by reference into this proxy statement/ prospectus.

Terms of the Merger

Each of the 1st Colonial board of directors and the Mid Penn board of directors has unanimously adopted the merger agreement. The merger agreement provides that, pursuant to the terms and subject to the conditions set forth in the merger agreement, 1st Colonial will merge with and into Mid Penn, with Mid Penn continuing as the surviving corporation, which is referred to as the merger. Promptly following the merger, 1st Colonial Bank, a wholly owned subsidiary of 1st Colonial, will be merged with and into Mid Penn Bank, a wholly owned subsidiary of Mid Penn, with Mid Penn Bank continuing as the surviving bank, which is referred to as the bank merger.

Subject to the terms and conditions of the merger agreement, at the effective time of the merger, each share of 1st Colonial common stock issued and outstanding at the effective time of the merger (other than certain excluded shares as described in the merger agreement, including 1st Colonial common stock held by a holder who has properly exercised dissenters’ rights in respect of such shares) will be converted into the right to elect to receive, subject to adjustment and proration, the cash consideration or the stock consideration. See the section entitled “The Merger Agreement — Consideration to Be Received in the Merger.”

1st Colonial shareholders are being asked to adopt and approve the merger agreement. See the section entitled “The Merger Agreement” for additional and more detailed information regarding the legal documents that govern the merger, including information about conditions to complete the merger and provisions for terminating or amending the merger agreement. Mid Penn shareholders are not entitled to voting rights in connection with the merger.

Background of the Merger

The 1st Colonial board of directors and management periodically evaluate the competitive environment, regulatory dynamics, and strategic alternatives in light of evolving market conditions and the company’s performance. In late February, Stephens introduced Robert B. White, the President and Chief Executive Officer of 1st Colonial, to the Chief Executive Officer of a certain financial institution (“Financial Institution A”) initiating discussions about a potential business combination. In late March, Stephens shared a preliminary merger analysis with both parties, held several one-on-one and joint meetings, and circulated the first model deck on March 20, 2025.

On March 26, 2025, Stephens presented “Strategic Optionality in a Shifting Environment” to the 1st Colonial board of directors, covering the overall market backdrop, 1st Colonial’s financial and operating performance during the most recent fiscal year, and strategic options including acquisitions, mergers, and an outright sale.

Following this presentation, the 1st Colonial board of directors authorized Mr. White and Stephens to engage with Financial Institution A, Mid Penn, and another financial institution (“Financial Institution B”) about potential business combinations. Financial Institution A’s discussions were already underway and authorized to continue; Stephens and Mr. White reached out to Mid Penn to gauge interest, and Mid Penn indicated an interest in engaging. Financial Institution B had a weaker stock currency at that time, so discussions with Financial Institution B were deferred until progress was made with the other two parties.

Throughout April and May 2025, 1st Colonial and Financial Institution A held multiple in-person and virtual meetings to evaluate a potential business combination, executed a non-disclosure agreement on April 28, 2025, and subsequently began exchanging non-public information. During April and into early May,

TABLE OF CONTENTS

at the request of Mid Penn and 1st Colonial, Stephens provided analysis of a potential Mid Penn-1st Colonial combination, including financial modeling and the sharing of non-public information.

By mid-May 2025, 1st Colonial received non-binding letters of intent from Financial Institution A and Mid Penn. Mid Penn’s proposal contemplated merger consideration of eighty percent (80%) stock and twenty percent (20%) cash with an indicative value of $17.50 to $18.50 per 1st Colonial share, based on an exchange ratio range of 0.4798x to 0.5072x and $3.50 to $3.70 in cash per share, using Mid Penn’s $29.18 per share five-day volume weighted average price (“VWAP”) as of May 9, 2025.

Financial Institution A’s proposal was all-stock consideration with an indicative value of $18.37 per share, with both Financial Institution A and Mid Penn valued at 1.1x tangible book value.

On May 15, 2025, the 1st Colonial board of directors convened a meeting to review the letters-of-intent authorized the soliciting of best-and-final bids from Financial Institution A and Mid Penn, and approved initiating contact with Financial Institution B.

On May 19, 2025, the non-disclosure agreement between 1st Colonial and Mid Penn was executed.

On May 30, 2025, a meeting with the 1st Colonial board of directors occurred.

With respect to Financial Institution A, the 1st Colonial board of directors expressed concerns about post-close execution risk related to Financial Institution A’s illiquid profile and the effective transition to a public company structure as part of the transaction. These concerns were communicated to Financial Institution A and its advisor, together with a request to add a cash component to the structure and to arrange for Financial Institution A to conduct a capital raise to fund that cash consideration component, with commitments obtained prior to any public merger announcement.

On June 10, 2025, the 1st Colonial board of directors met to review updated combination offers from Financial Institution A and Mid Penn, consider a Financial Institution B non-binding indication of interest, and hear a presentation and Q&A from Financial Institution A’s Chief Executive Officer.

At that meeting, the revised terms presented were as follows:

•

Financial Institution A at $18.37 per share with a 70/30 stock-and-cash mix;

•

Mid Penn at $18.50 per share with 60/40 stock-and-cash mix; and

•

Financial Institution B at $15.01 per share, all stock.

On June 11, 2025, 1st Colonial executed Financial Institution A’s term sheet with exclusivity, incorporating the following items requested by the 1st Colonial board of directors:

•

targeting a transaction announcement around July 21 or 22 of 2025, subject to satisfactory diligence;

•

determining the pro forma brand strategy before signing;

•

securing signed capital commitments before announcement; and

•

supporting a post-closing capital raise (a formal initial public offering) within roughly a year of closing, market permitting, with a contemplated $30 – $50 million primary raise to improve float, liquidity and shareholder composition.

In support of the proposed transaction with Financial Institution A, due diligence continued through June and July of 2025 concurrent with the drafting and negotiation of the merger agreement. In late June 2025, concerns emerged regarding reverse due diligence of Financial Institution A, particularly around credit quality and credit philosophy. In early to mid-July, the 1st Colonial board of directors determined not to proceed with the Financial Institution A opportunity after identifying significant credit risk factors that would substantially increase the execution risk associated with the business combination. Notice of this determination was provided to Financial Institution A on July 16, 2025. A revised offer was submitted by Financial Institution A on July 17, 2025, including a fifty percent (50%) increase in cash as part of the updated terms. Following review by the 1st Colonial board of directors and management, the revised offer of Financial Institution A was rejected by a 1st Colonial letter dated July 21, 2025. Following the expiration of

TABLE OF CONTENTS

exclusivity on July 25, 2025, Stephens contacted Mid Penn’s President and Chief Executive Officer, Rory G. Ritrievi, to gauge continued interest in pursuing a transaction with Mid Penn.

On July 31, 2025, an updated letter-of-intent was shared by Mid Penn reflecting a sixty percent (60%) stock forty percent (40%) cash consideration structure, an indicative value of $18.78 per share, an exchange ratio of 0.4167 and $7.40 in cash per share.

On August 22, 2025, representatives from 1st Colonial conducted on-site due diligence at Mid Penn headquarters, including interviews of management and representatives.

On August 26, 2025, Mid Penn’s legal counsel, Holland & Knight LLP (“Holland & Knight”), circulated an initial draft of the merger agreement to 1st Colonial and its counsel, Stradley Ronon Stevens & Young, LLP (“Stradley Ronon”). Between August 26, 2025, and September 24, 2025, representatives of 1st Colonial and Mid Penn, with the assistance of Holland & Knight and Keefe Bruyette & Woods, Inc. (“KBW”), on behalf of Mid Penn, and Stradley Ronon and Stephens, on behalf of 1st Colonial, negotiated the specific terms of the merger agreement. These negotiations included a mechanism, proposed by Stradley Ronon, allowing 1st Colonial shareholders to elect to receive either cash or stock as merger consideration, as well as the related ancillary documents and agreements, including disclosure schedules and the form of affiliate letter. In addition, between September 12, 2025 and September 24, 2025 1st Colonial and Mid Penn engaged in open dialogue and negotiations relating to the employment agreements to be entered into by Mid Penn Bank and Robert B. White.

Throughout the course of negotiations, legal counsel for both parties had several conversations with management of their respective clients regarding the developments and progress of the negotiations and received continued input from management regarding the issues emerging from such negotiations, including the terms most important to each respective management team.

On September 19, 2025, the 1st Colonial board of directors held a special meeting to review and consider the merger proposal as set forth in the definitive merger agreement and related documents negotiated by 1st Colonial and Mid Penn and their respective advisors. The 1st Colonial board of directors received a presentation regarding the results of due diligence conducted on Mid Penn from 1st Colonial’s management.

On September 24, 2025, after careful and deliberate consideration of the presentations as well as consideration of the best interests of 1st Colonial’s shareholders, customers, employees and communities served by 1st Colonial, the 1st Colonial board of directors unanimously (i) determined that the merger agreement and the transactions contemplated thereby were advisable and fair to and in the best interests of 1st Colonial, (ii) approved and adopted the merger agreement and approved the merger and the other transactions contemplated thereby and (iii) subject to the 1st Colonial board of director’s need to properly discharge its fiduciary duties, recommended the approval and adoption of the merger agreement and the transactions contemplated thereby by the 1st Colonial shareholders.

Also on September 24, 2025, the Mid Penn board of directors met in a special session to analyze and consider the merger agreement and the transactions and agreements contemplated thereby. Mid Penn’s legal counsel, Holland & Knight, reviewed the key financial and legal terms of the merger agreement. Representatives of KBW reviewed with the Mid Penn board of directors’ financial matters regarding the proposed merger transaction. After additional discussion and deliberation, the Mid Penn board of directors unanimously approved and adopted the merger agreement and the transactions and agreements contemplated thereby and determined that such transactions were in the best interests of Mid Penn and its shareholders. Following the respective meetings of the Mid Penn board of directors and the 1st Colonial board of directors, Mid Penn and 1st Colonial exchanged signature pages to the merger agreement and executed the merger agreement on September 24, 2025. Shortly thereafter 1st Colonial and Mid Penn issued a joint press release announcing the parties had entered into a definitive agreement for a proposed merger, providing for the material terms of the merger, including the consideration structure, and that subject to customary closing conditions, the closing is expected to occur in the first or second quarter of 2026.

1st Colonial’s Reasons for the Merger; Recommendation of the 1st Colonial Board of Directors

In reaching its conclusion to adopt and approve the merger, the merger agreement and the other transactions contemplated by the merger agreement and related transaction documents, and to recommend

TABLE OF CONTENTS

that the 1st Colonial shareholders vote “ FOR ” adoption and approval of the merger agreement, the 1st Colonial board of directors, at its meeting held on September 24, 2025, considered the merger and the merger agreement and determined it to be fair, advisable and in the best interests of 1st Colonial, its shareholders and its other constituencies. The 1st Colonial board of directors unanimously voted in favor of the merger and the merger agreement and the transactions contemplated thereby. In evaluating the merger, the 1st Colonial board of directors consulted with management, as well as 1st Colonial’s legal and financial advisors, and considered a number of factors, including:

•

a review of 1st Colonial’s current business, operations, earnings, financial condition and prospects and of Mid Penn’s current business, operations, earnings, financial condition and prospects, taking into account its familiarity with Mid Penn, its management and the results of 1st Colonial’s due diligence review of Mid Penn;

•

knowledge of the current environment in the financial services industry, including economic conditions, the continuing consolidation, increasing operating costs resulting from regulatory initiatives and compliance mandates, increasing competition from larger regional institutions, the growing private lending sector and current financial market conditions and the likely effects of these factors on 1st Colonial’s potential growth, productivity and strategic options;

•

the terms and conditions of the merger, including both the amount and nature of the consideration proposed to be paid in connection with the merger and assessment of the likelihood by the 1st Colonial board of directors that the merger would be completed in a timely manner;

•

the financial presentation of Stephens, including its opinion, dated September 24, 2025, as more fully described below under the section entitled “ Opinion of 1st Colonial’s Financial Advisor ;”

•

the review with 1st Colonial’s outside legal counsel of the material terms of the merger agreement, including the representations, warranties, covenants, deal protection and termination provisions;

•

the fact that the merger permits a portion of the consideration to be paid in cash;

•

the fact that 1st Colonial shareholders will receive a significant premium;

•

the fact that structure of the merger is intended to qualify as a tax-free reorganization which means the Mid Penn stock can be received tax-free while any cash received will be taxable

•

the strong capital base the resulting combined institution would have after the merger;

•

the expansion of the Mid Penn board of directors to include one member of the 1st Colonial board of directors;

•

the fact that 1st Colonial’s stock has limited liquidity and that Mid Penn’s stock trades on The Nasdaq Stock Market which provides greater liquidity;

•

the fact that the merger is not expected to result in significant employment loss for current 1st Colonial employees;

•

the fact that no 1st Colonial Bank branch closings are anticipated; and

•

the opportunity to offer 1st Colonial’s customers additional products and services through Mid Penn’s product and service offerings.

The 1st Colonial board of directors also considered a variety of risks and other potentially negative factors concerning the merger, including, without limitation, the following factors:

•

the risk that potential benefits of the merger, including possible synergies, might not be realized;

•

the possibility that the consummation of the merger may be delayed, or not occur;

•

the incurrence of substantial expenses related to the merger, including transaction expenses and integration costs;

•

the time commitment of and dedication of resources by management to effectuate the merger;

•

the risk of potential adverse effects on business and customer relationships as a result of the merger; and

TABLE OF CONTENTS

•

the other potential risks described under the section entitled “ Risk Factors ” in this proxy statement/ prospectus and the risks included in Mid Penn’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 incorporated by reference into this proxy statement/prospectus.

The foregoing discussion of the information and factors considered by the 1st Colonial board of directors is not exhaustive. In view of the wide variety of factors considered by the 1st Colonial board of directors in connection with its evaluation of the merger and the complexity of these matters, the 1st Colonial board of directors did not consider it practical to, and did not attempt to, quantify, rank or otherwise assign relative weights to the specific factors that it considered in reaching its decision. The 1st Colonial board of directors evaluated the factors described above.

In considering the factors described above, individual members of the 1st Colonial board of directors may have given different weights to different factors. It should also be noted that this explanation of the reasoning of the 1st Colonial board of directors and all other information presented in this section and many other statements throughout the proxy/prospectus are forward-looking in nature and, therefore, should be read in light of the factors discussed under the section entitled “ Cautionary Statement Regarding Forward-Looking Statements ” on page 19 .

Recommendation of the 1st Colonial Board of Directors

The 1st Colonial board of directors believes that the terms of the transaction are in the best interests of 1st Colonial and its shareholders and has unanimously approved the merger and the merger agreement. Accordingly, the 1st Colonial board of directors unanimously recommends that the 1st Colonial shareholders vote “FOR” the approval of the 1st Colonial merger.

Opinion of 1st Colonial’s Financial Advisor

On August 1, 2025, 1st Colonial engaged Stephens to act as financial adviser to 1st Colonial in connection with the proposed sale of 1st Colonial and/or its subsidiary bank, 1st Colonial Bank. In connection with its engagement, and following the negotiation of the proposed merger with Mid Penn, Stephens was requested to undertake a study of the fairness, from a financial point of view, of the proposed merger of 1st Colonial and its bank subsidiary with and into Mid Penn and its bank subsidiary. 1st Colonial engaged Stephens because, among other factors, Stephens is a nationally recognized investment banking firm with substantial experience in similar transactions. As part of its investment banking business, Stephens is continually engaged in the valuation of financial services businesses and their securities in connection with mergers and acquisitions.

As part of Stephens’ engagement, representatives of Stephens participated in a meeting of the 1st Colonial board of directors held on September 24, 2025, in which the 1st Colonial board of directors considered and approved the proposed merger. At this meeting, Stephens reviewed the financial aspects of the proposed merger and rendered its oral opinion, which was subsequently confirmed by delivery of a written opinion to the 1st Colonial board of directors dated as of September 24, 2025, that, as of such date, the consideration to be received by the common stockholders of 1st Colonial (solely in their capacity as such) in the proposed merger was fair to them from a financial point of view, based upon and subject to the qualifications, assumptions and other matters considered by Stephens in connection with the preparation of its opinion.

The full text of Stephens’ written opinion letter (the “Opinion Letter”) is attached as Annex B to this proxy statement/prospectus.

The summary of the opinion set forth in this document is qualified in its entirety by reference to the full text of such written Opinion Letter.

TABLE OF CONTENTS

addresses whether the consideration to be received by the common stockholders of 1st Colonial (solely in their capacity as such) in the proposed merger was fair to them from a financial point of view as of the date of the opinion. The opinion does not address the underlying business decision of 1st Colonial to engage in the proposed merger or any other term or aspect of the merger agreement or the transactions contemplated thereby. Stephens’ opinion does not constitute a recommendation to the 1st Colonial board of directors or any of the 1st Colonial shareholders as to how such person should vote or otherwise act with respect to the proposed merger or any other matter. 1st Colonial and Mid Penn determined the merger consideration through a negotiation process.

In connection with developing its opinion, Stephens:

(i)

reviewed certain publicly available financial statements and reports of Mid Penn;

(ii)

reviewed certain audited financial statements regarding 1st Colonial and Mid Penn;

(iii)

reviewed certain internal financial statements, management reports and other financial and operating data concerning 1st Colonial and Mid Penn prepared by management of 1st Colonial and management of Mid Penn, respectively;

(iv)

reviewed, on a pro forma basis, in reliance upon financial projections and other information and assumptions concerning 1st Colonial and Mid Penn provided by management of 1st Colonial and management of Mid Penn, as applicable, and upon consensus research estimates concerning Mid Penn, the effect of the proposed merger on the balance sheet, capitalization ratios, earnings and tangible book value both in the aggregate and, where applicable, on a per share basis of Mid Penn;

(v)

reviewed the reported prices and trading activity for the common stock of 1st Colonial and Mid Penn;

(vi)

compared the financial performance of 1st Colonial and Mid Penn with that of certain other publicly-traded companies and their securities that Stephens deemed relevant to Stephens’ analysis of the proposed merger;

(vii)

(viii)

reviewed the then most recent draft of the merger agreement and related documents provided to Stephens by 1st Colonial;

(ix)

discussed with management of 1st Colonial and management of Mid Penn the operations of and future business prospects for 1st Colonial and Mid Penn, respectively and the anticipated financial consequences of the proposed merger to 1st Colonial and Mid Penn, respectively;

(x)

assisted in 1st Colonial’s deliberations regarding the material terms of the proposed merger and 1st Colonial’s negotiations with Mid Penn; and

(xi)

performed such other analyses and provided such other services as Stephens deemed appropriate.

Stephens relied on the accuracy and completeness of the information, financial data and financial forecasts provided to Stephens by 1st Colonial and Mid Penn and of the other information reviewed by Stephens in connection with the preparation of Stephens’ opinion, and its opinion was based upon such information. Stephens did not independently verify or undertake any responsibility to independently verify the accuracy or completeness of any of such information, data or forecasts. Management of 1st Colonial assured Stephens that it was not aware of any relevant information that had been omitted or remained undisclosed to Stephens. Stephens did not assume any responsibility for making or undertaking an independent evaluation or appraisal of any of the assets or liabilities of 1st Colonial or of Mid Penn, and Stephens was not furnished with any such evaluations or appraisals; nor did Stephens evaluate the solvency or fair value of 1st Colonial or of Mid Penn under any laws relating to bankruptcy, insolvency or similar matters. Stephens did not assume any obligation to conduct any physical inspection of the properties, facilities, assets or liabilities (contingent or otherwise) of 1st Colonial or Mid Penn. Stephens did not receive or

TABLE OF CONTENTS

review any individual loan or credit files nor did Stephens make an independent evaluation of the adequacy of the allowance for credit losses of 1st Colonial or Mid Penn. Stephens did not make an independent analysis of the effects of potential future changes in the rate of inflation or of prevailing rates of interest or other market developments or disruptions, or of the effects of any global conflicts or hostilities or any other disaster or adversity, on the business or prospects of 1st Colonial or Mid Penn. With respect to the financial projections or forecasts prepared by management of 1st Colonial and management of Mid Penn, including the forecasts of potential cost savings and potential synergies, Stephens also assumed that such financial projections or forecasts had been reasonably prepared and reflected the best then currently available estimates and judgments of management of 1st Colonial and management of Mid Penn, respectively, as to the future financial performance of 1st Colonial and Mid Penn, respectively, and provided a reasonable basis for Stephens’ analysis. Stephens recognized that such financial projections or forecasts were based on numerous variables, assumptions and judgments that were inherently uncertain (including, without limitation, factors related to general economic and competitive conditions) and that actual results could vary significantly from such projections or forecasts, and Stephens expressed no opinion as to the reliability of such financial projections, forecasts or estimates or the assumptions upon which they were based.

Stephens does not provide legal, accounting, regulatory, or tax advice or expertise, and Stephens relied solely, and without independent verification, on the assessments of 1st Colonial and its other advisors with respect to such matters. Stephens assumed, with 1st Colonial’s consent, that the proposed merger will not result in any materially adverse legal, regulatory, accounting or tax consequences for 1st Colonial or its shareholders and that any reviews of legal, accounting, regulatory or tax issues conducted as a result of the proposed merger will be resolved favorably to 1st Colonial and its shareholders. Stephens did not express any opinion as to any tax or other consequences that might result from the proposed merger

Stephens’ opinion was necessarily based upon market, economic and other conditions as they existed and could be evaluated on the date of the opinion, and on the information made available to Stephens as of the date of the opinion. Market price data used by Stephens in connection with its opinion was based on reported market closing prices as of September 23, 2025. It should be understood that subsequent developments may affect the opinion and that Stephens did not undertake any obligation to update, revise or reaffirm the opinion or otherwise comment on events occurring after the date of the opinion. Stephens further noted that volatility or disruptions in the credit and financial markets relating to, among other things, potential future changes in the rate of inflation or prevailing rates of interest or other market developments or disruptions, or the effects of any global conflicts or hostilities or any other disaster or adversity, may or may not have an effect on 1st Colonial or Mid Penn, and Stephens did not express an opinion as to the effects of such volatility or disruptions on the proposed merger or any party to the proposed merger. Stephens further expressed no opinion as to the prices at which shares of 1st Colonial common stock or Mid Penn common stock may trade at any time subsequent to the announcement of the proposed merger.

In connection with developing its opinion, Stephens assumed that, in all respects material to its analyses:

(i)

the proposed merger and any related transactions will be consummated on the terms of the latest draft of the merger agreement provided to Stephens, without material waiver or modification;

(ii)

the representations and warranties of each party in the merger agreement and in all related documents and instruments referred to in the merger agreement are true and correct;

(iii)

each party to the merger agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents;

(iv)

all conditions to the completion of the proposed merger will be satisfied within the time frames contemplated by the merger agreement without any waivers;

(v)

that in the course of obtaining the necessary regulatory, lending or other consents or approvals (contractual or otherwise) for the proposed merger and any related transactions, no restrictions, including any divestiture requirements or amendments or modifications, will be imposed that would

TABLE OF CONTENTS

have a material adverse effect on the contemplated benefits of the proposed merger to the common stockholders of 1st Colonial;

(vi)

there has been no material change in the assets, liabilities, financial condition, results of operations, business or prospects of 1st Colonial or Mid Penn since the date of the most recent financial statements made available to Stephens, and that no legal, political, economic, regulatory or other development has occurred that will adversely impact 1st Colonial or Mid Penn; and

(vii)

the proposed merger will be consummated in a manner that complies with applicable law and regulations.

Stephens’ opinion was limited to whether the consideration to be received by the common stockholders of 1st Colonial (solely in their capacity as such) in the proposed merger was fair to them from a financial point of view as of the date of the opinion. Stephens was not asked to, and it did not, offer any opinion as to the terms of the merger agreement or the form of the proposed merger or any aspect of the proposed merger, other than the fairness, from a financial point of view, of the consideration to be received in the proposed merger by the common stockholders of 1st Colonial (solely in their capacity as such). The opinion did not address the merits of the underlying decision by 1st Colonial to engage in the proposed merger, the merits of the proposed merger as compared to other alternatives potentially available to 1st Colonial or the relative effects of any alternative transaction in which 1st Colonial might engage, nor is it intended to be a recommendation to any person or entity as to any specific action that should be taken in connection with the proposed merger, including with respect to how to vote or act with respect to the proposed merger. Moreover, Stephens did not express any opinion as to the fairness of the amount or nature of the compensation to any of 1st Colonial’s officers, directors or employees, or to any group of such officers, directors or employees, whether relative to the compensation to other shareholders of 1st Colonial or otherwise.

The following is a summary of the material financial analyses performed and material factors considered by Stephens in connection with developing its opinion. In performing the financial analyses described below, Stephens relied on the financial and operating data, projections and other financial information and assumptions concerning 1st Colonial and Mid Penn provided by management of 1st Colonial and management of Mid Penn, as applicable, and Stephens reviewed with 1st Colonial’s executive management certain assumptions concerning 1st Colonial and Mid Penn upon which the analyses were based, as well as other factors. Although this summary does not purport to describe all of the analyses performed or factors considered by Stephens, it does set forth those analyses considered by Stephens to be material in arriving at its opinion. The preparation of a fairness opinion is a complex analytic process involving various determinations as to the appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. The order of the summaries of analyses described does not represent the relative importance or weight given to those analyses by Stephens. It should be noted that in arriving at its opinion, Stephens did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, Stephens believes that its analysis must be considered as a whole and that considering any portion of such analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion. The financial analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the financial analyses summarized below. Accordingly, Stephens’ analyses and the summary of its analyses must be considered as a whole, and selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying Stephens’ analyses and opinion.

Summary of Proposed Merger:

Pursuant to the merger agreement, and subject to the terms, conditions and limitations set forth therein, and for purposes of its opinion, Stephens understood that, subject to potential adjustments as described in the merger agreement, the aggregate consideration expected to be received by the holders of the outstanding common stock, options and warrants of 1st Colonial is approximately $101.1 million, based

TABLE OF CONTENTS

on the closing price of Mid Penn’s common stock of $30.31 as of September 23, 2025. Such consideration, subject to potential adjustment, will consist of (i) the obligation to pay approximately $2.3 million in cash in respect of the cancellation of outstanding options on 1st Colonial common stock, and (ii) with respect to each outstanding share of 1st Colonial common stock (including restricted shares), the right to receive, at the election of the holder thereof, either $18.50 in cash or 0.6945 shares of Mid Penn common stock, with such elections subject to proration such that, in the aggregate, 40% of 1st Colonial’s common stock will be converted into cash consideration and 60% into stock consideration. Based upon the unaudited financial information of 1st Colonial as of and for the twelve months ended June 30, 2025, and market data as of September 23, 2025, Stephens calculated the following transaction multiples:

	Transaction Value / Reported Tangible Book Value (at June 30, 2025)					1.16 x
	Transaction Value / Most Recent Quarter Annualized (“MRQA”) Core Earnings (1)					15.5 x
	Transaction Value / Last-Twelve-Months (“LTM”) Core Earnings (1)					13.5 x
	Transaction Value / 2025 Estimated Earnings (2)					12.8 x
	Transaction Value / 2026 Estimated Earnings (2)					11.5 x
	Core Deposit Premium (3)					2.7 %

Stephens considered these selected transactions to be reasonably similar, but not identical or directly comparable, to the proposed merger. A complete analysis involves complex considerations and qualitative judgments concerning differences in the selected transactions and other factors that could affect the transaction values in those selected transactions as compared with the proposed merger. Mathematical analysis (such as determining the median) is not in itself a meaningful method of using selected transaction data. Stephens compared certain proposed transaction multiples of the proposed merger to the 25 th percentile, median, and 75 th percentile transaction multiples of the selected transactions:

Discounted Cash Flow Analysis — 1st Colonial:

Stephens performed a standalone discounted cash flow analysis of 1st Colonial to estimate a range of implied equity values for 1st Colonial based upon the discounted net present value of the projected after-tax

TABLE OF CONTENTS

free cash flows for 1st Colonial for the projected period. In this analysis, Stephens used (i) financial information and data provided by 1st Colonial and (ii) financial forecasts and projections provided by the executive management team of 1st Colonial. See the section entitled “ Certain Unaudited Prospective Financial Information ” for additional information regarding the unaudited prospective financial information provided to Stephens by 1st Colonial management and approved by 1st Colonial for Stephens’ use and reliance in performing its analysis. Stephens determined the projected amount of cash flow for 1st Colonial based on (i) annual dividend payments for earnings and excess capital (if any) above a tangible common equity to tangible asset ratio of 9.0% from 2025 to 2030, and (ii) a range of standalone terminal values derived by applying price to last-twelve-months earnings per share multiples ranging from 10.0x to 14.0x to 1st Colonial’s estimated end of period net income at December 31, 2030. To reconcile net income to future cash flow, Stephens applied adjustments for (a) a pre-tax opportunity cost of cash of 4.33% and (b) a marginal tax rate of 21%.

In selecting the terminal price to earnings per share multiples, Stephens considered the trading multiples of 1st Colonial and of the comparable publicly traded banks and thrifts discussed in the sections entitled “Relevant Regional Major Exchange-Traded Public Companies” and “Relevant Mid-Atlantic Over-the-Counter Public Companies Analysis”. Exercising its professional judgment, Stephens selected a range of 10.0x to 14.0x as the terminal price to earnings per share multiples. The following table summarizes the range of terminal values of 1st Colonial that Stephens calculated based upon 1st Colonial’s estimated end of period net income at December 31, 2030 and the range of terminal price to earnings per share multiples of 10.0x to 14.0x:

	2030 1st Colonial End of Period Net Income				$	11.8					$	11.8					$	11.8					$	11.8					$	11.8
	x Terminal Multiple					10.0 x						11.0 x						12.0 x						13.0 x						14.0 x
	Terminal Value				$	117.7					$	129.5					$	141.2					$	153.0					$	164.8

Stephens then discounted the projected future cash flows and terminal values to present value using discount rates ranging from 13.0% to 15.0%, which Stephens selected to reflect estimates of 1st Colonial’s cost of equity. Based on this analysis, Stephens derived a range for the implied equity value of 1st Colonial from $15.70 per share to $22.07 per share.

The discounted cash flow analysis is a widely used valuation methodology, but the results of this methodology are highly dependent on the assumptions that must be made, including asset and earnings growth rates, terminal values, capital levels, and discount rates. The analysis did not purport to be indicative of the actual values or expected values of 1st Colonial. The actual results may vary from the projected results, any of these assumptions might not be realized in future operations and the variations may be material.

Miscellaneous:

The preparation of a fairness opinion is a complex process and is not susceptible to a partial analysis or summary description. Stephens believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering the analyses taken as a whole, would create an incomplete view of the process underlying its opinion. In addition, Stephens considered the results of all such analyses and did not assign relative weights to any of the analyses, but rather made qualitative judgments as to significance and relevance of each analysis and factor, so the results from any particular analysis described above should not be taken to be the view of Stephens.

In performing its analyses, Stephens made numerous assumptions with respect to industry performance, general business, economic and regulatory conditions and other matters, many of which are beyond the control of 1st Colonial. The analyses performed by Stephens are not necessarily indicative of actual values, trading values or actual future results which might be achieved, all of which may be significantly more or less favorable than suggested by such analyses. The analyses do not purport to be appraisals or to reflect the prices at which companies may actually be sold, and such estimates are inherently subject to uncertainty.

Stephens is serving as financial adviser to 1st Colonial in connection with the proposed merger and is entitled to receive from 1st Colonial reimbursement of its expenses and a fee in the amount of 1.50% of the

TABLE OF CONTENTS

aggregate transaction consideration received by 1st Colonial or its common stockholders at the closing of the proposed merger for Stephens’ services as financial advisor to 1st Colonial, a significant portion of which is contingent upon the consummation of the proposed merger. Stephens also received a fee in the amount of $500,000 from 1st Colonial upon rendering its fairness opinion, which opinion fee will be credited in full against the fee which will become payable to Stephens upon the closing of the proposed merger. 1st Colonial has also agreed to indemnify Stephens against certain claims and liabilities that could arise out of Stephens’ engagement, including certain liabilities that could arise out of Stephens’ providing its fairness opinion.

Stephens issues periodic research reports regarding the business and prospects of Mid Penn, and Stephens makes a market in the stock of Mid Penn. Stephens has provided investment banking services to Mid Penn in recent years, including serving as financial advisor in connection with Mid Penn’s acquisitions of Brunswick Bancorp and William Penn Bancorporation, which closed on May 19, 2023 and April 30, 2025, respectively, and as an underwriter on a follow-on offering of Mid Penn’s common stock which priced on November 1, 2024. Stephens received the following fees for providing such investment banking services to Mid Penn: (i) $400,000 for Mid Penn’s acquisition of Brunswick Bancorp, (ii) $1,000,000 for Mid Penn’s acquisition of William Penn Bancorporation and (iii) $2,215,730 for Mid-Penn’s follow-on offering. Stephens has not received fees for providing investment banking services to 1st Colonial within the past two years. Stephens expects to pursue future investment banking services assignments with participants in the proposed merger.

In the ordinary course of its business, Stephens Inc. and its affiliates and employees at any time may hold long or short positions, and may trade or otherwise effect transactions as principal or for the accounts of customers, in debt, equity or derivative securities of participants in the proposed merger.

Interests of Certain 1st Colonial Directors and Executive Officers in the Merger

In addition to their interests as 1st Colonial shareholders, directors and executive officers of 1st Colonial may have interests in the merger that are different from or in addition to interests of other 1st Colonial shareholders. These interests include, among others, provisions in the merger agreement regarding officer titles, as well as change in control agreements, employment agreements, indemnification, insurance, and eligibility to participate in employee benefit plans.

For purposes of the 1st Colonial agreements and plans, the completion of the merger will constitute a change in control. These additional interests may create potential conflicts of interest and cause some of these persons to view the merger differently than a 1st Colonial shareholder may view it. The financial interests of 1st Colonial’s directors and executive officers in the merger include the following:

•

the retention of Mr. Robert White, the President and Chief Executive Officer of 1st Colonial, and payment of compensation to such executive officer, pursuant to an employment agreement and change in control severance agreement between Mid Penn and Mr. White that will become effective at the closing of the merger;

•

1st Colonial’s executive officers will be entitled to severance or change-in-control benefits upon the closing of the merger;

•

accelerated vesting of 1st Colonial restricted stock units and 1st Colonial options to executive officers and directors of 1st Colonial; and

•

the retention of one director of 1st Colonial to serve on the Mid Penn board of directors and to be compensated in accordance with Mid Penn policies.

The 1st Colonial board of directors was aware of these interests and considered them, among other matters, in evaluating and negotiating the merger agreement and the merger, in approving the merger agreement and the merger and in recommending to the 1st Colonial shareholders that they vote “ FOR” the 1st Colonial merger proposal and the 1st Colonial adjournment proposal. For more information, see the sections entitled “ The Merger — Background of the Merger ” beginning on page 28 and “ The Merger — 1st Colonial’s Reasons for the Merger; Recommendation of the 1st Colonial Board of Directors ” beginning on page 30 . Such interests are described in more detail below.

TABLE OF CONTENTS

For purposes of this disclosure, the only executive officers of 1st Colonial are Mr. White and Ms. Mary Kay Shea, Chief Financial Officer of 1st Colonial.

Treatment of 1st Colonial Equity Awards

The 1st Colonial executive officers and directors hold equity awards granted by 1st Colonial.

Under the terms of the merger agreement, at the effective time, each 1st Colonial option, whether vested or unvested, that is outstanding and unexercised immediately prior to the effective time will be cancelled and converted into the right to receive a single lump sum cash payment by Mid Penn, equal to the product of (i) the number of shares of 1st Colonial common stock subject to such 1st Colonial Option immediately prior to the effective time of the merger, and (ii) the excess, if any, of (A) $18.50 over (B) the exercise price per share of such 1st Colonial Option (the “option merger consideration”), less any applicable taxes required to be withheld with respect to such payment and less all applicable payroll deductions; provided, however, that if the exercise price per share of any such 1st Colonial option is equal to or greater than $18.50, such 1st Colonial option will be cancelled at the effective time without any cash payment being made in respect thereof. The option merger consideration (less all applicable payroll deductions and tax withholdings) will be paid on the first or second payroll date after the closing of the merger. Ten (10) days prior to the closing date, 1st Colonial will accelerate the vesting of all unvested 1st Colonial options that are then outstanding, and will provide the holders of all 1st Colonial options with notice of their right to exercise such 1st Colonial options at any time prior to the effective time and the consequences of not exercising their 1st Colonial options prior to the effective time.

In addition, under the terms of the merger agreement, 1st Colonial will take all actions necessary, such that (i) within (5) five days prior to the closing date, (a) any vesting restrictions on each then outstanding 1st Colonial restricted stock unit granted under a 1st Colonial’s equity compensation plans will automatically lapse, (b) each then outstanding 1st Colonial restricted stock unit will be cancelled at the time of such acceleration and settled (with one share of 1st Colonial common stock being issued in settlement of each 1st Colonial restricted stock unit then being settled), provided, that the number of shares of 1st Colonial common stock issued in settlement of any such 1st Colonial restricted stock unit be net of any applicable tax withholding obligations in accordance with appliable law and (c) all accrued but unpaid dividend equivalents on the 1st Colonial restricted stock units settled pursuant to the preceding clause (d) have been paid to the holder of such 1st Colonial restricted stock units less all applicable tax withholdings and payroll deductions) and (ii) on the closing date, no 1st Colonial restricted stock units will be outstanding.

The following table sets forth the aggregate number of unvested 1st Colonial options and 1st Colonial restricted stock units held by each of 1st Colonial executive officers and directors, plus an approximation of the value that each of them may become entitled to receive in connection with their outstanding unvested equity awards, assuming continued employment or service through the completion of the merger:

Includes 1,700 unvested 1st Colonial restricted stock units for each director that will vest in December 2025 in accordance with the time-based vesting schedule.

(3)

Does not include 1,250 1st Colonial restricted stock units that will be granted to each director in December 2025 (11,250 restricted stock units in the aggregate) in accordance with 1st Colonial’s annual restricted stock grant schedule, all of which will be subject to vesting acceleration as a result of the completion of the merger. The estimated value of such 1st Colonial restricted stock units to each director in connection with the completion of the merger is $23,125, calculated by multiplying 1,250 shares underlying each 1st Colonial restricted stock unit grant times $18.50 per share.

Existing Employment Agreements

Each of Mr. White and Ms. Shea are parties to an employment agreement with 1st Colonial Bank pursuant to which they are entitled to receive a payment upon the occurrence of a change in control of 1st Colonial, subject to their continued employment with 1st Colonial Bank through the closing of such change in control. Mr. White’s payment equals 2.99 times the sum of his base salary and target bonus for the year of the change in control, while Ms. Shea’s bonus equals 2.00 times the sum of her base salary and target bonus for the year of the change in control. Based on their respective base salaries and target bonus opportunities, Mr. White’s change in control bonus is expected to be approximately $1,883,700, and Ms. Shea’s change in control bonus is expected to be approximately $784,000. These bonuses are required to be paid promptly after the closing of the merger, but 1st Colonial has decided to pay at least $1,100,000 of Mr. White’s bonus in December 2025 subject to a requirement that he repay the after-tax portion of such amounts back to 1st Colonial if the merger does not occur. Mr. White and Ms. Shea must remain employed by 1st Colonial on the date of the change in control as a condition to receiving their change in control bonus.

Under the terms of Ms. Shea’s employment agreement with 1st Colonial, if her employment terminates for any reason on or after the occurrence of a change in control, then she is not entitled to receive any severance benefits other than if she is not offered continued employment following the change in control, in which case she is entitled to up to 18 months of the payment of her and her eligible dependents’ monthly medical, dental and vision insurance premiums pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”) (or a monthly cash payment equal to 1.7 times such amount). In addition, Ms. Shea is entitled to reimbursement of her legal fees in the event that she prevails in any claim under the agreement. Ms. Shea’s COBRA payments are expected to be approximately $93,416 based on Mid Penn Bank’s current COBRA rates and Ms. Shea’s existing healthcare elections, and are payable only if she timely executes and does not revoke a release of claims.

Mr. White’s employment agreement with 1st Colonial will terminate at the closing of the merger, at which time Mr. White’s employment agreement with Mid Penn Bank (as described below) will become effective, provided that Mr. White will remain eligible to receive his change in control bonus described above.

New Robert B. White Agreements

Robert B. White Employment Agreement

In connection with the execution of the merger agreement, Mid Penn Bank entered into an employment agreement with Robert B. White, to be effective as of the closing of the merger.

The employment agreement provides that Mr. White will be appointed by Mid Penn Bank as a Senior Executive Vice President of Mid Penn Bank, and will serve as Market President for the Greater Philadelphia Metro Area, and Senior Risk Advisor. The term of employment begins on the closing of the merger and

TABLE OF CONTENTS

lasts for two (2) years, with automatic two-year renewals on each anniversary of the effective date unless either party gives at least sixty (60) days’ written notice of non-renewal or the agreement is otherwise terminated. Both Mr. White and Mid Penn Bank may terminate Mr. White’s employment prior to the end of the term, as provided in the employment agreement.

Under the terms of the employment agreement, Mr. White’s annual base salary is initially set at $425,000.16, and he is eligible to participate in any short-term performance plan made available to executives of Mid Penn Bank. In addition, within thirty (30) days after the closing of the merger, Mr. White will receive a $10,000 sign-on bonus (subject to repayment if employment ends within ninety (90) days after the closing of the merger, other than due to a termination by Mid Penn Bank without cause). Mr. White also is eligible for at least twenty-six (26) days of paid time off per year, stock-based incentives, participation in employee benefit plans, use of a company automobile (with Mid Penn Bank covering maintenance, insurance, and fuel), and a paid country club membership (initiation fee and annual dues) if approved by Mid Penn Bank in its discretion.

In the event that Mr. White’s employment is terminated by Mid Penn Bank without cause or by Mr. White for good reason (as the terms “cause” and “good reason” are defined in Mr. White’s employment agreement with Mid Penn Bank), Mr. White is entitled to continued base salary for the greater of six (6) months and the remainder of the term of his employment agreement, and reimbursement for (or payment of a monthly cash amount equal to 1.7 times) his and his eligible dependents’ monthly medical, prescription drug, dental and vision premiums pursuant to COBRA for the duration of his severance period (but not in excess of eighteen (18) months). Payment of such severance benefits is subject to Mr. White’s execution and non-revocation of a release of claims, and compliance with his restrictive covenants. The estimated amount of this severance is $920,892 (with the COBRA portion being based on Mid Penn Bank’s current COBRA rates and Mr. White’s existing healthcare elections). In addition, in the case of a termination of Mr. White’s employment by Mid Penn Bank without cause, he has the option of buying his company car from Mid Penn Bank at its reported value, assuming the lease (if such car is leased and such assumption is permitted under the terms of the lease agreement) or returning such car to Mid Penn Bank with no further liability to Mr. White.

Mr. White is also entitled to certain rights to indemnification under his employment agreement relating to the business of Mid Penn Bank or Mid Penn.

Robert B. White Change in Control Severance Agreement

In connection with the execution of the merger agreement, Mid Penn Bank entered into a change in control severance agreement with Mr. White, to be effective as of the closing of the merger.

The term of the agreement will commence upon the closing of the merger and will continue for a period of three (3) years thereafter (with automatic one-year renewals on each anniversary of the effective date unless at least ninety (90) days prior to any renewal date, notice of non-renewal is provided). However, if a change in control (as defined in the agreement) occurs during the term of the agreement, then the agreement will continue in effect for a limited period of two (2) years after the date of such change in control, unless terminated sooner in accordance with the terms of the agreement.

Under the terms of the agreement, if Mr. White’s employment is terminated by Mid Penn Bank without cause or by Mr. White for good reason (as the terms “cause” and “good reason” are defined in the agreement), in either case, on or within two years after a change in control of Mid Penn, Mr. White is entitled to (x) a lump sum cash payment within 60 days after such termination of employment equal to 2.5 times his highest base salary during the 12 months prior to the change in control, (y) reimbursement for (or payment of a monthly cash amount equal to 1.7 times) his and his eligible dependents’ monthly medical, dental and vision premiums pursuant to COBRA for up to 18 months and (z) a payment equal to 1.7 times his and his eligible dependents’ monthly medical, dental and vision premiums pursuant to COBRA for up to twelve (12) months after the end of the eighteen (18) month period described in clause (y). Payment of such severance benefits is subject to Mr. White’s execution and non-revocation of a release of claims, and compliance with his restrictive covenants. The estimated amount of such severance is $1,180,653 (with the COBRA portion being based on Mid Penn Bank’s current COBRA rates and Mr. White’s existing healthcare elections).

TABLE OF CONTENTS

In addition, Mr. White is entitled to reimbursement of his legal fees in the event that he prevails in any claim under the agreement following a change in control.

Director Appointment and Compensatory Arrangements

Mid Penn has agreed in the merger agreement that, upon completion of the merger, Thomas Brugger, the 1st Colonial nominee, will be appointed to serve on the Mid Penn board of directors and will be compensated in accordance with the policies of Mid Penn, which are anticipated to be substantially similar to the current policies of Mid Penn as described in its definitive proxy statement filed with the SEC on March 28, 2025, under the heading “Compensation of the Board.”

Additionally, Mid Penn shall offer members of the 1 st Colonial board of directors (other than the 1st Colonial Nominee) a one-year paid advisory board position in accordance with Mid Penn compensation authorities and policies. Certain members of the 1st Colonial board of directors may accept the annual cash payment in lieu of service on the advisory board.

Director and Officer Indemnification and Insurance

The merger agreement provides that Mid Penn is required to indemnify, defend, and hold harmless all current and former officers, directors, and employees of the 1st Colonial and its subsidiaries against any losses, claims, damages, costs (including attorneys’ fees), liabilities, or settlements arising from their service prior to September 24, 2025.

Additionally, Mid Penn must maintain, or cause Mid Penn Bank to maintain, 1st Colonial’s current directors’ and officers’ liability insurance policies for six (6) years following the effective time, covering acts or omissions occurring at or prior to the effective time. Mid Penn may substitute equivalent coverage, but is not required to spend more than 200% of 1st Colonial’s current annual premium (the “maximum amount”) necessary to maintain or procure such directors’ and officers’ liability insurance coverage. If equivalent coverage cannot be obtained for a premium equal to the maximum amount, Mid Penn must secure the best available coverage for that amount. Alternatively, a six-year “tail” policy under the 1st Colonial’s existing directors’ and officers’ insurance policy may be purchased, with Mid Penn’s consent, provided it may be obtained for an amount that does not exceed the maximum amount.

For information on the indemnification and insurance being offered to the 1st Colonial directors and officers please see the section entitled “ The Merger Agreement — Director and Officer Indemnification and Insurance ” beginning on page 65 .

Accounting Treatment of the Merger

Mid Penn and 1st Colonial prepare their respective financial statements in accordance with GAAP. The merger will be accounted for as an acquisition of 1st Colonial by Mid Penn under the acquisition method of accounting, and Mid Penn will be treated as the acquirer for accounting purposes.

Governance of Mid Penn and Mid Penn Bank Following the Merger

The Mid Penn articles and the Mid Penn bylaws in effective immediately prior to the effective time will be the articles of incorporation and bylaws, respectively, of Mid Penn, as the surviving corporation, at the effective time, until thereafter amended as provided therein and in accordance with applicable law.

The Mid Penn Bank articles of incorporation and the Mid Penn Bank bylaws in effect immediately prior to the effective time of the bank merger will be the articles of incorporation and bylaws, respectively, of Mid Penn Bank, as the surviving bank, at the bank merger effective time, until thereafter amended as provided therein and in accordance with applicable law.

TABLE OF CONTENTS

merger. Mid Penn will offer all directors of 1st Colonial in office as of the effective time, other than the 1st Colonial nominee, a one-year paid advisory board position.

Robert B. White, the current President and Chief Executive Officer of 1st Colonial and 1st Colonial Bank, will be appointed as Senior Executive Vice President, Greater Philadelphia Metro Area Market President and Senior Risk Advisor of Mid Penn Bank at the bank merger effective time and each of the executive officers of Mid Penn and Mid Penn Bank as of immediately prior to the effective time and the bank merger effective time will continue to serve in the same positions of Mid Penn and Mid Penn Bank following the merger and the bank merger.

Public Trading Markets

Mid Penn common stock is listed for trading on Nasdaq under the symbol “MPB” and 1st Colonial common stock is quoted on the OTC Markets Group Pink Limited Market under the symbol “FCOB.” Following the merger, shares of Mid Penn common stock will continue to be traded on Nasdaq. In connection with the completion of the merger, 1st Colonial common stock currently listed on the OTC Markets Group Pink Limited Market will be delisted from the OTC Markets Group Pink Limited Market.

Under the merger agreement, Mid Penn will file a notification of listing of additional shares of Mid Penn common stock to be issued in the merger prior to the effective time and in accordance with Nasdaq’s rules, and Mid Penn will also take all other action required to effectuate the listing of such additional shares pursuant to such rules. The merger agreement provides that neither Mid Penn or 1st Colonial will be required to complete the merger if such notification is not filed or if further action is required to authorize such additional shares for listing.

Regulatory Approvals

To complete the merger and the bank merger, Mid Penn and 1st Colonial need to obtain approvals or consents from, or make filings with, a number of U.S. federal and state bank and other regulatory authorities. Subject to the terms of the merger agreement, Mid Penn and 1st Colonial have agreed to cooperate with each other and use their commercially reasonable efforts to promptly prepare and file all necessary documentation, to obtain as promptly as practicable all permits, consents, waivers approvals and authorizations of all third parties and governmental entities that are necessary or advisable to consummate the merger, the bank merger and the other transactions contemplated by the merger agreement, and to use their reasonable best efforts to address any conditions in any regulatory approval. The term “requisite regulatory approvals” means all regulatory consents, registrations, approvals (and the expiration or termination of all statutory waiting periods in respect thereof), permits and authorizations required to be obtained prior to and in order to effect the consummation of the merger and the bank merger from the Federal Reserve Board, the FDIC, the PDB and the NJDB and as otherwise set forth in the merger agreement that are necessary to consummate the transactions contemplated by the merger agreement, including the merger and the bank merger, or those the failure of which to be obtained would reasonably be expected to have a material adverse effect; and no such approval, authorization or consent will include any condition or requirement excluding standard conditions that are normally imposed by the regulatory authorities in bank merger transactions, that would, in the good faith reasonable judgment of the either the Mid Penn board of directors or the 1st Colonial board of directors, materially reduce the benefits of the merger to such a degree that either 1st Colonial or Mid Penn would not have entered into the merger agreement had such condition, restriction or requirement been known at the date of the merger agreement (a “materially burdensome regulatory condition”).

Under the terms of the merger agreement, Mid Penn and 1st Colonial and their subsidiaries will not voluntarily take any action, in connection with obtaining the foregoing permits, consents, approvals and authorizations of governmental entities or regulatory agencies that would, or would be reasonably likely to, materially adversely affect or delay that ability of the parties to obtain any such approvals or materially increase the period of time necessary to obtain such approvals, or materially adversely affect or delay its ability to perform its covenants and agreements under the merger agreement.

The approval of an application means only that the statutory and regulatory criteria for approval have been satisfied or waived. It does not mean that the approving authority has determined that the consideration

TABLE OF CONTENTS

to be received by 1st Colonial shareholders in the merger is fair. Regulatory approval does not constitute an endorsement or recommendation of the merger.

Mid Penn and 1st Colonial believe that the merger and the bank merger do not raise significant regulatory concerns and that they will be able to obtain all requisite regulatory approvals. However, there can be no assurance that all of the regulatory approvals described below will be obtained and, if obtained, there can be no assurances regarding the timing of the approvals, the companies’ ability to obtain the approvals on satisfactory terms or the absence of litigation challenging such approvals. In addition, there can be no assurance that such approvals will not impose conditions or requirements that, individually or in the aggregate, would or could reasonably be expected to have an adverse effect on the financial condition, results of operations, assets or business of Mid Penn following the completion of the merger. There can likewise be no assurances that United States federal or state regulatory authorities will not attempt to challenge the merger or, if such a challenge is made, what the result of such challenge will be.

Federal Reserve Board

The transactions contemplated by the merger agreement require approval of the Federal Reserve Board pursuant to Section 3 of the Bank Holding Company Act of 1956, as amended (the “BHC Act”), unless the Federal Reserve Board waives that requirement. Mid Penn submitted a waiver request to the Federal Reserve Board on or around November 24, 2025.

If the Federal Reserve Board does not grant Mid Penn’s waiver request, Mid Penn will seek prior approval of the merger pursuant to and in accordance with the requirements of Section 3 of the BHC Act. The Federal Reserve Board takes into consideration a number of factors when acting on applications under Section 3 of the BHC Act (12 U.S.C. § 1842(c)) and Section 225.13 of Regulation Y (12 C.F.R. § 225.13). These factors include the financial condition of the holding companies and banks involved and the future prospects of the combined organization (including consideration of the current and projected capital positions and the levels of indebtedness) and its managerial resources (including the competence, experience, and integrity of the officers, directors and principal shareholders, as well as their record of compliance with applicable laws and regulations). The Federal Reserve Board also considers the effectiveness of the applicant in combating money laundering, the convenience and needs of the communities to be served, as well as the extent to which the proposal would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. The Federal Reserve Board may not approve a proposal that would have significant adverse effects on competition or on the concentration of resources in any banking market.

In considering an application under Section 3 of the BHC Act, the Federal Reserve Board also reviews the records of performance of the relevant insured depository institutions under the Community Reinvestment Act of 1977 (the “CRA”), pursuant to which the Federal Reserve Board must also take into account the record of performance of each of Mid Penn and 1st Colonial in meeting the credit needs of the entire community, including low- and moderate-income neighborhoods, served by their depository institution subsidiaries. As part of the review process in merger transactions, the Federal Reserve Board frequently receives protests from community groups and others. In their most recent CRA performance evaluations, Mid Penn Bank received an overall “Satisfactory” rating and 1st Colonial Bank received an overall “Satisfactory” rating.

In addition, in connection with interstate merger and bank merger transactions, the Federal Reserve Board considers certain additional factors under the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994, as amended, including the capital position of the acquiring bank holding company, or bank, as the case may be, relevant state laws regarding the minimum age of the bank to be acquired, the concentration of deposits on a nationwide and statewide basis, and compliance with any applicable state community reinvestment and antitrust laws.

Federal Deposit Insurance Corporation

The bank merger is subject to the prior approval of the FDIC under Section 18(c) of the Federal Deposit Insurance Act (the “Bank Merger Act”). In evaluating an application filed under the Bank Merger Act, the FDIC generally considers: (1) the competitive impact of the transaction, (2) the financial and managerial resources of the depository institutions party to the bank merger and the future prospects of the

TABLE OF CONTENTS

resulting institution, (3) the depository institutions’ effectiveness in combating money-laundering activities, (4) the convenience and needs of the communities to be served, and (5) the extent to which the bank merger would result in greater or more concentrated risks to the stability of the United States banking or financial system. The FDIC also reviews the performance records of the relevant depository institutions under the CRA, including their CRA ratings.

The initial submission of the application under the Bank Merger Act to the FDIC occurred on or around November 24, 2025.

Pennsylvania Department of Banking and Securities and New Jersey Department of Banking and Insurance

The bank merger is subject to the approval by the Commissioner of the PDB pursuant to the Pennsylvania Banking Code of 1965 and the Commissioner of the NJDB pursuant to the New Jersey Banking Act of 1948, as amended. The PDB will review to determine whether the bank merger complies with Pennsylvania law and the NJDB will review to determine whether the bank merger complies with New Jersey law. The criteria considered by the PDB and the NJDB are similar to those considered by the FDIC.

The initial submissions to the PDB and NJDB occurred on or around November 24, 2025.

Public Notice and Comments

The BHC Act, the Bank Merger Act as well as Federal Reserve Board and FDIC regulations require published notice of, and the opportunity for public comment on, the applications to the Federal Reserve Board and the FDIC. The Federal Reserve Board and the FDIC take into account the views of third-party commenters, particularly on the subject of the merging parties’ CRA performance and record of service to their communities. These agencies are also authorized to hold one or more public hearings or meetings if these agencies determine that such hearings or meetings would be appropriate. The receipt of written comments or any public meeting or hearing could prolong the period during which the application is under review by these agencies.

Department of Justice Review and Waiting Periods

In addition to the Federal Reserve Board, the Antitrust Division of the Department of Justice (the “DOJ”) conducts a concurrent competitive review of the merger to analyze the competitive effects of the merger and determine whether the merger would result in a violation of the antitrust laws. Transactions approved under Section 3 of the BHC Act or the Bank Merger Act generally may not be completed until thirty (30) days after the approval of the applicable federal agency is received, during which time the DOJ may challenge the transaction on antitrust grounds. With the approval of the applicable federal agency and the concurrence of the DOJ, the waiting period may be reduced to no less than 15 days. The commencement of an antitrust action would stay the effectiveness of such an approval unless a court specifically ordered otherwise. In reviewing the merger, the DOJ could analyze the merger’s effect on competition differently than the Federal Reserve Board or the FDIC, and, thus, it is possible that the DOJ could reach a different conclusion than the Federal Reserve Board or the FDIC regarding the merger’s effect on competition. A determination by the DOJ not to object to the merger may not prevent the filing of antitrust actions by private persons or state attorneys general. There can be no assurance if and when DOJ clearance will be obtained, or as to the conditions or limitations that such DOJ approval may contain or impose.

Additional Regulatory Approvals and Notices

Additional notifications and/or applications requesting approval may be submitted to various other federal, state and non-U.S. regulatory authorities and self-regulatory organizations, including but not limited to notifications and/or applications to certain state financial services and banking regulators with respect to Mid Penn Bank maintaining the existing 1st Colonial Bank offices in those states.

TABLE OF CONTENTS

THE MERGER AGREEMENT

This section of the proxy statement/prospectus describes the material terms of the merger agreement. The description in this section and elsewhere in this proxy statement/prospectus is subject to, and qualified in its entirety by reference to, the merger agreement, which is attached to this proxy statement/prospectus as Annex A and is incorporated by reference into this proxy statement/prospectus. This summary does not purport to be complete and may not contain all the information about the merger agreement that is important to you. We urge you to read the full text of the merger agreement, as it is the legal document governing the merger.

Explanatory Note Regarding the Merger Agreement

The merger agreement and this summary of terms are included to provide you with information regarding the terms of the merger agreement. Factual disclosures about Mid Penn and 1st Colonial contained in this proxy statement/prospectus and/or in the public reports of Mid Penn filed with the SEC (as described in the section entitled “ Where You Can Find More Information ” beginning on page 96 ) may supplement, update or modify the factual disclosures about Mid Penn contained in the merger agreement. The merger agreement contains representations and warranties by Mid Penn, on the one hand, and representations and warranties by 1st Colonial, on the other hand, made solely for the benefit of the other. The representations, warranties and covenants made in the merger agreement by Mid Penn and 1st Colonial were qualified and subject to important limitations agreed to by Mid Penn and 1st Colonial in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of establishing circumstances in which a party to the merger agreement may have the right not to consummate the merger if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders and some were qualified by the matters contained in the confidential disclosure schedules that Mid Penn and 1st Colonial each delivered in connection with the merger agreement. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since the date of the merger agreement. Accordingly, the representations and warranties in the merger agreement should not be relied on by any persons as characterizations of the actual state of facts about Mid Penn and 1st Colonial at the time they were made or otherwise and should be read only in conjunction with the other information provided elsewhere in this proxy statement/prospectus.

Structure of the Merger

Each of the 1st Colonial board of directors and the Mid Penn board of directors has unanimously adopted the merger agreement. The merger agreement provides that, pursuant to the terms and subject to the conditions set forth in the merger agreement, 1st Colonial will merge with and into Mid Penn, with Mid Penn continuing as the surviving corporation in the merger. Promptly following the merger, 1st Colonial Bank, a wholly owned subsidiary of 1st Colonial, will be merged with and into Mid Penn Bank, a wholly owned subsidiary of Mid Penn, with Mid Penn Bank continuing as the surviving bank in the bank merger.

The merger agreement provides that Mid Penn, with the written consent of 1st Colonial, may change the method of effecting the merger if and to the extent it deems such change to be desirable, except that no such change will (i) alter the amount or kind of merger consideration provided for in the merger agreement, (ii) materially impede or delay the completion of the merger, (iii) result in any adverse federal or state income tax or other adverse tax consequences to 1st Colonial shareholders or (iv) require submission to or approval of 1st Colonial shareholders after the merger agreement has been approved by 1st Colonial shareholders.

Closing and Effective Time of the Merger

The merger will become effective as set forth in the statement of merger to be filed with the Department of State of the Commonwealth of Pennsylvania. It currently is anticipated that the effective time of the

TABLE OF CONTENTS

merger will occur in the first quarter or early in the second quarter of 2026, but we cannot guarantee when or if the merger will be completed.

Consideration to Be Received in the Merger

The merger agreement provides that 1st Colonial shareholders will have the right, with respect to each of their shares of 1st Colonial common stock, to elect to receive, subject to certain proration, adjustment and other provisions as described below, either (A) 0.6945 of a share of Mid Penn common stock or (B) $18.50. Sixty percent (60%) of 1st Colonial common stock outstanding as of the effective time will be converted into the stock consideration and the remaining forty percent (40%) will be converted into the cash consideration.

No guarantee can be made that you will receive the form of merger consideration that you elect. As a result of the proration provisions and other limitations described in this proxy statement/prospectus and in the merger agreement, you may receive Mid Penn common stock or cash in amounts that vary from the amounts you elect to receive. The proration of stock and cash to be issued in the merger is also subject to potential adjustment to ensure that the merger will qualify as a reorganization under the Code (i.e., to satisfy the continuity of interest test).

Non-Electing 1st Colonial Shareholders

1st Colonial shareholders who make no election for cash consideration or stock consideration in the merger or who do not make a valid election will be deemed to have elected either stock consideration or cash consideration depending on the proration adjustments required by the merger agreement (discussed below under the section entitled “ ― Proration ”).

Proration

The total number of shares of 1st Colonial common stock (including shares of 1st Colonial common stock issued prior to the effective time for exercises of 1st Colonial options and vesting of 1st Colonial restricted stock units) entitled to receive the stock consideration will be equal to sixty percent (60%) of the number of shares of 1st Colonial common stock outstanding immediately prior to the effective time. Similarly, the total number of shares of 1st Colonial common stock (including restricted stock) entitled to receive the cash consideration will be equal to forty percent (40%) of the number of shares of 1st Colonial common stock outstanding immediately prior to the effective time.

To achieve this, if the aggregate number of shares of 1st Colonial common stock with respect to which an election to receive the cash consideration (the “cash election shares”) exceeds forty percent (40%) of all issued and outstanding shares of 1st Colonial common stock immediately prior to the effective time, all shares of 1st Colonial common stock to which an election to receive the stock consideration (the “stock election shares”) applies and all non-election shares will be converted into the right to receive stock consideration and the cash election shares will be converted into the right to receive the cash consideration by multiplying such shares by a fraction, the numerator of which is forty percent (40%) of all issued and outstanding shares of 1st Colonial common stock and the denominator of which is the number of cash election shares, with the remaining cash election shares being converted into the right to receive stock consideration.

Conversely, if the number of cash election shares is less than forty percent (40%) of the all issued and outstanding shares of 1st Colonial common stock immediately prior to the effective time (this amount being referred to as the “shortfall number”), then all cash election shares will be converted into the right to receive the cash consideration and the non-election shares and the stock election shares will be treated in the following manner:

•

if the shortfall number is less than or equal to the number of non-election shares, then all stock election shares will be converted into the right to receive stock consideration and the non-election shares will be converted into the right to receive cash consideration by multiplying the number of non-election shares by a fraction, the numerator of which is the shortfall number and the denominator of which is the total number of non-election shares, with the remaining non-election shares being converted into the right to receive the stock consideration; or

•

if the shortfall number exceeds the number of non-election shares, all non-election shares will be converted into the right to receive the cash consideration and the stock election shares will be converted into the right to receive the cash consideration by multiplying the number of stock election shares by a fraction, the numerator of which is the amount by which the shortfall number exceeds the total number of non-election shares and the denominator of which is the total number of stock election shares, with the remaining stock election shares being converted into the right to receive the stock consideration.

Treatment of Fractional Shares

No fractional shares of Mid Penn common stock will be issued upon the surrender for exchange of certificates representing shares of 1st Colonial common stock or book-entry shares of 1st Colonial common stock, no dividend or distribution with respect to Mid Penn common stock will be payable on or with respect to any fractional share, and such fractional share interests will not entitle the owner thereof to vote or to any other rights of a shareholder of Mid Penn. In lieu of the issuance of any such fractional share, Mid Penn will pay to each 1st Colonial shareholder who otherwise would be entitled to receive such fractional share an amount in cash rounded to the nearest cent without interest, equal to the product of the fractional share interest as such 1st Colonial shareholder would otherwise be entitled multiplied by $18.50.

Treatment of 1st Colonial Equity Awards

1st Colonial Options

At the effective time, each 1st Colonial option, whether vested or unvested, that is outstanding and unexercised immediately prior to the effective time will be cancelled and converted into the right to receive a single lump sum cash payment by Mid Penn, equal to the product of (i) the number of shares of 1st Colonial common stock subject to such 1st Colonial option immediately prior to the effective time, and (ii) the excess, if any, of (A) $18.50 over (B) the exercise price per share of such 1st Colonial option, less any applicable withholding taxes and less applicable payroll deductions; provided, however, that if the exercise price per share of any such 1st Colonial option is equal to or greater than $18.50, such 1st Colonial option will be cancelled at the effective time without any cash payment being made in respect thereof.

Election Procedures; Exchange of Shares

Election Procedures

If you own 1st Colonial common stock, you will receive under separate cover an election form. The election form entitles the record holder of 1st Colonial common stock to specify (A) the number of shares of 1st Colonial common stock owned by such holder for which the holder elects to receive stock consideration and (B) the number of shares of 1st Colonial common stock owned by such holder for which the holder elects to receive cash consideration. If no election is made, then such holders will be deemed a non-electing shareholder and such non-election shares will be treated as set forth above.

To make an effective election, a 1st Colonial shareholder of record must submit a properly completed election form to Computershare, Inc., which will be acting as the exchange agent, on or before 5:00 p.m., Eastern Time, on the 25th day following the mailing date of the election form to 1st Colonial (the “election deadline”). Any 1st Colonial shareholder may, at any time prior to the election deadline, change or revoke his or her election by written notice received by the exchange agent prior to the election deadline accompanied by a properly completed and signed, revised election form. All elections will be revoked automatically if the merger agreement is terminated.

Elections may not be revoked or changed following the election deadline.

If a properly completed election form is not submitted or the election form is not revoked, prior to the election deadline, such shares of 1st Colonial common stock will be designated as non-election shares and treated as set forth above.

Exchange Procedures

Promptly after the effective time of but in no event later than five (5) business days thereafter, Mid Penn will cause the exchange agent to mail or deliver to each person who was, immediately prior to the effective time, a holder of record of 1st Colonial common stock, notice advising such holder of the effectiveness of the merger, including a form of letter of transmittal (in a form satisfactory to Mid Penn and 1st Colonial) containing instructions for use in effecting the surrender of certificates representing shares of 1st Colonial common stock in exchange for the merger consideration, as well as cash in lieu of fractional shares and any dividends or distributions to be paid as described in “― Dividends and Distributions ” below. Upon surrender to the exchange agent of a certificate or book-entry shares for cancellation, together with a duly executed and completed letter of transmittal, such 1st Colonial shareholder will be provided in exchange therefor, a Mid Penn stock certificate, or at the election of Mid Penn, a statement reflecting shares issued in book-entry form, representing the stock consideration to which such 1st Colonial shareholder is entitled to pursuant to the terms of the merger agreement, plus a check for the cash consideration (including cash in lieu of fractional shares and any dividends or other distributions to be paid as described in the section entitled “― Dividends and Distributions ” below).

Withholding

The exchange agent, Mid Penn, 1st Colonial and their respective affiliates will be entitled to deduct and withhold from the cash consideration, any cash in lieu of fractional shares of Mid Penn and any other

TABLE OF CONTENTS

amounts or property otherwise payable or distributable to any 1st Colonial shareholder pursuant to the merger agreement (including with respect to any 1st Colonial option or 1st Colonial restricted stock unit) such amounts as they are required to deduct and withhold under the Code or any provision of federal, state, local or non-U.S. tax law. To the extent that such amounts are withheld by the exchange agent, Mid Penn, 1st Colonial or their respective affiliates, as the case may be, such withheld amounts will be treated for all purposes of the merger agreement as having been paid to the holder in respect of whom such deduction and withholding was made by the exchange agent, Mid Penn, 1st Colonial or their respective affiliates, as the case may be.

Dividends and Distributions

No dividends or other distributions declared after the effective time with respect to Mid Penn common stock will be paid to the holder of any unsurrendered certificate representing shares of 1st Colonial common stock until the holder surrenders such certificate in accordance with the merger agreement. After the surrender of a certificate in accordance with the merger agreement, the record holder thereof will be entitled to receive, without any interest thereon, any such dividends or other distributions with a record date after the effective time, which theretofore had become payable with respect to shares of Mid Penn common stock.

Appraisal Rights

To the extent that 1st Colonial shareholders are entitled to appraisal rights under Subchapter D of Chapter 15 of the PBCL, dissenting shares will not be converted into the right to receive the merger consideration, but the holders of such dissenting shares will be entitled to receive such consideration as will be determined pursuant to Subchapter D of Chapter 15 of the PBCL (it being understood and acknowledged that at the effective time, such dissenting shares will no longer be outstanding, will automatically be cancelled and will cease to exist and such holder will cease to have any rights with respect thereto other than the right to receive the “fair value” of such dissenting shares as determined in accordance with Subchapter D of Chapter 15 of the PBCL). If any dissenting shareholder fails to perfect or effectively withdraws or loses his, her or its right to appraisal and payment under the PBCL (whether occurring before, at or after the effective time), such holder’s shares of 1st Colonial common stock will be deemed to have been converted as of the effective time into the right to receive the merger consideration, without any interest thereon, and such shares will not be deemed to be dissenting shares.

Under the terms of the merger agreement, if more than five percent (5%) of the aggregate outstanding shares of 1st Colonial common stock have properly notified Mid Penn of their intent to exercise appraisal rights under applicable law, then Mid Penn will not be obligated to complete the merger.

See the section entitled “ Appraisal Rights ” and Annex C to this proxy statement/prospectus.

Each of Mid Penn and 1st Colonial has agreed to additional covenants which include, among other things, commitments to provide certain financial and regulatory information upon request and maintain insurance in reasonable amounts.

Regulatory Matters

Employee Matters

Pursuant to the terms of the merger agreement, and subject to the requirements of the Code and ERISA and the terms of 1st Colonial’s employee benefit plans, Mid Penn may elect to continue to maintain separately, consolidate, merge, freeze or terminate 1st Colonial’s employee benefit plans.

coverage on the same basis it provides such coverage to Mid Penn employees. With respect to any continuing employee, Mid Penn will use commercially reasonable efforts to cause any coverage limitation under Mid Penn’s employee benefit plans due to any pre-existing conditions to be waived by the Mid Penn employee benefit plan to the degree that such condition was waived or satisfied under the corresponding 1st Colonial employee benefit plan. Solely with respect to the plan year that includes the closing date, Mid Penn will use commercially reasonable efforts to cause the applicable Mid Penn employee benefit plan that is a medical, prescription drug, dental or vision plan to recognize any expenses incurred by a continuing employee (or any dependent thereof) under the corresponding medical, prescription drug, dental or vision plan of 1st Colonial in the plan year that includes the closing date for purposes of determining any applicable deductible and annual out of pocket expense under such Mid Penn employee benefit plan.

In the event (i) Mid Penn terminates the employment (other than for circumstances reasonably constituting cause) of any continuing employee (other than continuing employees who are subject to employment, change of control or similar contracts), or (ii) such continuing employee is not offered or retained in substantially comparable employment, with respect to job description, responsibilities, work location (it being understood that any work location that is located within thirty-five (35) miles of the continuing employee’s work location as of the closing date will be deemed “substantially comparable” for purposes of the merger agreement) and pay, with Mid Penn or Mid Penn Bank, as applicable, then Mid Penn will pay severance benefits to such individuals as follows: (A) in the event employment is terminated on the closing date or within one (1) year after the closing date, two (2) weeks’ salary for each full year of continuous service with 1st Colonial, with a minimum severance benefit of four (4) weeks and a maximum severance benefit of twenty-six (26) weeks; or (B) in the event employment is terminated after the one (1) year anniversary of the closing date, in accordance with the then existing severance policy of Mid Penn or its successor; provided, however, that Mid Penn’s obligation to pay severance to any continuing employee pursuant to the foregoing will be expressly conditioned on the timely receipt by Mid Penn of a release in such form and substance as deemed acceptable by Mid Penn in its sole and absolute discretion. From and after the effective time, Mid Penn will permit all continuing employees whose employment is terminated without cause as of the effective time by Mid Penn, 1st Colonial or any of its subsidiaries to participate in Mid Penn’s outplacement services plan for employees of Mid Penn and its subsidiaries, which outplacement services will be provided for a period of not less than six (6) months following the termination of employment by an outplacement agency selected by Mid Penn.

Director and Officer Indemnification Insurance

Following the effective time, to the fullest extent permitted under Pennsylvania law and the 1st Colonial articles of incorporation and the 1st Colonial bylaws, Mid Penn will indemnify, defend and hold harmless, and subject to the indemnified party providing an undertaking to repay such advances if it is ultimately determined that such indemnified party is not entitled to indemnification, will advance expenses as incurred to (to the fullest extent as permitted by Pennsylvania law and under 1st Colonial’s articles of incorporation and 1st Colonial’s bylaws as in effect as of the date of the merger agreement) each current and former director, officer or employee of 1st Colonial or 1st Colonial Bank against all losses, claims, damages, liabilities, costs, expenses (including attorney’s fees), judgments or amounts paid in settlement in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, whether before or after the effective time, arising out of the fact that such person is or was a director, officer or employee of 1st Colonial or any of its subsidiaries and pertaining to matters existing or occurring at or prior to the effective time, including transactions contemplated by the merger agreement.

The merger agreement provides that Mid Penn will, or will cause Mid Penn Bank to, maintain in effect for a period of six (6) years following the effective time, 1st Colonial’s current directors’ and officers’ liability insurance policies, or policies of at least the same coverage and amount and containing terms and conditions that are not less advantageous than the current policy, with respect to acts or omissions occurring prior to the effective time of the merger. However, Mid Penn is not required to expend more than two hundred percent (200%) of the annual cost currently expended by 1st Colonial with respect to such insurance (the “maximum amount”), and if the amount of the annual premium necessary to maintain or procure such insurance coverage exceeds the maximum amount, Mid Penn will maintain the most advantageous policies of directors’ and officers’ insurance obtainable for a premium equal to the maximum amount. In lieu of the foregoing, Mid Penn or 1st Colonial, in consultation with, but only upon the consent of Mid Penn,

TABLE OF CONTENTS

may (and at the request of Mid Penn, 1st Colonial will use its reasonable best efforts to) obtain at or prior to the effective time a six (6) year “tail” policy under 1st Colonial’s existing directors’ and officers’ insurance policy provided equivalent coverage to that described in the preceding sentence and to the extent that the same may be obtained for an amount that does not exceed the maximum amount.

Agreement Not to Solicit Other Offers

Subject to specified exceptions summarized below, 1st Colonial has agreed that it will not, and will cause any of its subsidiaries and cause its and their respective officers, directors, employees, investment bankers, financial advisors, attorneys, accountants, consultants, affiliates and other agents not to, directly or indirectly, (i) initiate, solicit, induce or encourage, or take any action to facilitate the making of, any inquiry, offer or proposal that constitutes or could reasonably be expected to lead to an acquisition proposal; (ii) respond to any inquiry relating to an acquisition proposal or acquisition transaction (each as defined below); (iii) recommend or endorse an acquisition transaction; (iv) participate in any discussions or negotiations regarding any acquisition proposal or furnish, or otherwise afford access, to any person (other than Mid Penn) any confidential or nonpublic information or data with respect to 1st Colonial or any of its subsidiaries or otherwise relating to a 1st Colonial acquisition proposal; (v) release any person from, waive any provisions of, or fail to enforce any confidentiality agreement or standstill agreement to which 1st Colonial is a party; or (vi) enter into any agreement, agreement in principle or letter of intent with respect to any acquisition proposal or approve or resolve to approve any acquisition proposal or any agreement, agreement in principle or letter of intent relating to an acquisition proposal.

For purposes of the merger agreement:

•

an “acquisition proposal” means, with respect to 1st Colonial, any inquiry, offer or proposal (other than an inquiry, offer or proposal from Mid Penn), whether or not in writing, contemplating, relating to, or that could reasonably be expected to lead to, an acquisition transaction;

•

an “acquisition transaction” means (A) any transaction or series of transactions involving any merger, consolidation, recapitalization, share exchange, liquidation, dissolution or similar transaction involving 1st Colonial or any of its subsidiaries; (B) any transaction pursuant to which any third party or group acquires or would acquire (whether through sale, lease or other disposition), directly or indirectly, any assets of 1st Colonial or any of its subsidiaries representing, in the aggregate, twenty-five percent (25%) or more of the assets of 1st Colonial and each of its subsidiaries on a consolidated basis; (C) any issuance, sale or other disposition of (including by way of merger, consolidation, share exchange or any similar transaction) securities (or options, rights or warrants to purchase or securities convertible into, such securities) representing twenty-five percent (25%) or more of the votes attached to the outstanding securities of 1st Colonial or any of its subsidiaries; (D) any tender offer or exchange offer that, if consummated, would result in any third party or group beneficially owning twenty-five percent (25%) or more of any class of equity securities of 1st Colonial or any of its subsidiaries; or (E) any transaction which is similar in form, substance or purpose to any of the foregoing transactions, or any combination of the foregoing; and

•

a “superior proposal” means any bona fide written proposal (on its most recently amended or modified terms, if amended or modified) made by a third party to enter into an acquisition transaction on terms that the 1st Colonial board of directors determines in its good faith judgment, after consultation with and having considered the advice of its outside legal counsel and, with respect to financial matters, its financial advisor (i) would, if consummated, result in the acquisition of greater than fifty percent (50%), of the issued and outstanding shares of 1st Colonial common stock or all, or substantially all, of the assets of 1st Colonial and its subsidiaries on a consolidated basis; (ii) would result in a transaction that involves consideration to the holders of the shares of 1st Colonial common stock that is more favorable, from a financial point of view, than the consideration to be paid to 1st Colonial’s shareholders pursuant to the merger agreement taking into account all factors relating to such proposed transaction deemed relevant by 1st Colonial’s board of directors, including without limitation, the amount and form of consideration, the timing of payment, the risk of consummation of the transaction, the financing thereof and all other conditions thereto (including any adjustments to the terms and conditions of such transactions proposed by Mid Penn in response

TABLE OF CONTENTS

to such acquisition proposal); and (iii) is reasonably likely to be completed on the terms proposed, in each case taking into account all legal, financial, regulatory and other aspects of the proposal.

However, the 1st Colonial board of directors will be permitted to engage in discussions or negotiations with any person that makes an acquisition proposal, but only if, (i) 1st Colonial has received a bona fide unsolicited written acquisition proposal that did not result in a breach of the merger agreement; (ii) the 1st Colonial board of directors determines in good faith, after consultation with and having considered the advice of its outside legal counsel and its independent financial advisor, that such acquisition proposal constitutes or is reasonably likely to lead to a superior proposal (defined above); (iii) at least two (2) business days prior to furnishing any non-public information to, or entering into discussions with, such person, 1st Colonial gives Mid Penn written notice of the identity of such person and of 1st Colonial’s intention to furnish nonpublic information to, or enter into discussions with such person; and (iv) prior to furnishing or affording access to any confidential or nonpublic information or data with respect to 1st Colonial or any of its subsidiaries or otherwise relating to an acquisition proposal, 1st Colonial receives from such person a confidentiality agreement with terms no less favorable to Mid Penn than those contained in the existing confidentiality agreement between 1st Colonial and Mid Penn and provides a copy of the same to Mid Penn. 1st Colonial must also promptly provide to Mid Penn any nonpublic information regarding 1st Colonial or any of its subsidiaries provided to any other person that was not previously provided to Mid Penn no later than the date of provision of such information to such other person.

1st Colonial has also agreed to promptly (and in any event within two (2) calendar days) notify Mid Penn in writing of receipt of any acquisition proposal, any request for non-public information that could reasonably be expected to lead to an acquisition proposal, or any inquiry with respect to or that could reasonably be expected to lead to an acquisition proposal,

1st Colonial Shareholder Meeting; Adverse Recommendation Change

1st Colonial has agreed to call a meeting of its shareholders for the purpose of voting upon the approval of the merger agreement to be held as promptly as practicable after the effectiveness of the registration statement of which this proxy statement/prospectus is a part and have the 1st Colonial board of directors unanimously recommend approval of the merger agreement to 1st Colonial shareholders (the “1st Colonial board recommendation”).

Subject to the exception described below, neither the 1st Colonial board of directors nor any committee thereof will (i) withdraw, qualify or modify or propose to withdraw, qualify or modify, in a manner adverse to Mid Penn in connection with the transactions contemplated by the merger agreement (including the merger), the 1st Colonial board recommendation, or make any statement, filing or release in connection with the 1st Colonial special meeting or otherwise, inconsistent with the 1st Colonial board recommendation (it being understood that taking a neutral position or no position with respect to an acquisition proposal will be considered an adverse modification of the 1st Colonial board recommendation); (ii) approve or recommend, or publicly propose to approve or recommend, any 1st Colonial acquisition proposal (as defined in the section entitled “— Agreement Not to Solicit Other Offers ” above) or (iii) enter into (or cause 1st Colonial or any of its subsidiaries to enter into) any letter of intent, agreement in principle, acquisition agreement or other agreement (A) related to any acquisition transaction or (B) requiring 1st Colonial to abandon, terminate or fail to consummate the merger or any other transaction contemplated by the merger agreement (any of the foregoing, a “recommendation change”).

Prior to the 1st Colonial special meeting, the 1st Colonial board of directors may approve or recommend to the 1st Colonial shareholders a superior proposal or make a recommendation change if it has provided at least five (5) business days’ notice to Mid Penn that a bona fide unsolicited written acquisition proposal received constitutes a superior proposal but only if, (i) the 1st Colonial board of directors has reasonably determined in good faith, after consultation with and having considered the advice of outside counsel and, with respect to financial matters, its financial advisor, that the failure to take such actions would be inconsistent with its fiduciary duties to 1st Colonial’s shareholders under applicable law and (ii) at the end of such five (5) business day period, after taking into account any such adjusted, modified or amended terms as may have been committed to in writing by Mid Penn, the 1st Colonial board of directors has again in good faith determined that the bona fide unsolicited written acquisition proposal receive constitutes a superior proposal.

TABLE OF CONTENTS

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

The following discussion addresses the material United States federal income tax consequences of the merger to a 1st Colonial shareholder who holds shares of 1st Colonial common stock as a capital asset. This discussion is based upon the Code, Treasury regulations promulgated under the Code, judicial authorities, published positions of the Internal Revenue Service (the “IRS”) and other applicable authorities, all as in effect on the date of this discussion and all of which are subject to change (possibly with retroactive effect) and to differing interpretations. It is also based upon factual representations contained in certificates of officers of Mid Penn and 1st Colonial. Future legislative, judicial, or administrative changes or interpretations which may or may not be retroactive, or the failure of any such facts or representations to be true, accurate and complete, may affect the statements and conclusions described in this discussion.

This discussion is not intended to be a complete description of all of the United States federal income tax consequences of the merger. Further, this discussion does not address all aspects of United States federal income taxation that may be relevant to 1st Colonial shareholders in light of their particular circumstances and does not address aspects of United States federal income taxation that may be applicable to 1st Colonial shareholders subject to special treatment under the Code (including but not limited to banks, financial institutions, trusts, estates, persons who hold shares of 1st Colonial common stock in an individual retirement account (“IRA”), 401(k) plans or similar tax-favored accounts, tax-exempt organizations, insurance companies, real estate investment trusts, regulated investment companies, dealers or brokers in securities or foreign currencies, traders in securities that elect to use a mark-to-market method of accounting, persons holding 1st Colonial common stock through a pass-through entity, 1st Colonial shareholders who hold their shares of 1st Colonial common stock as part of a hedge, straddle, conversion transaction or constructive sale transaction, 1st Colonial shareholders who acquired their shares of 1st Colonial common stock pursuant to the exercise of employee stock options or otherwise as compensation, persons that hold options or warrants to acquire 1st Colonial common stock, persons whose functional currency for United States federal income tax purposes is not the United States dollar, persons who are United States expatriates and holders who are not “United States persons”, within the meaning of Section 7701(a)(30) of the Code). For purposes of this discussion, a beneficial owner of 1 st Colonial common stock that is considered a “United States person” within the meaning of section 7701(a)(30) of the Code is referred to as a “U.S. holder”. In addition, the discussion does not address any aspect of state, local or foreign taxation. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax aspects set forth below.

No ruling has been or will be requested from the IRS regarding the tax consequences of the merger. Moreover, the opinions described in this discussion are not binding on the IRS, and these opinions would not prevent the IRS from challenging the United States federal income tax treatment of the merger. Because of the complexities of the tax laws in general, and the complexities of the tax consequences associated with the receipt of cash in the merger in particular, holders of 1st Colonial common stock are encouraged to consult their tax advisors with respect to the particular United States federal, state, local and foreign tax consequences of the merger. This section is not intended to be tax advice to any shareholder.

Tax Opinions

The closing of the merger is conditioned, in part, upon the receipt by Mid Penn of the opinion of Holland & Knight, and the receipt by 1st Colonial of the opinion of Stradley Ronon, each dated as of the effective date of the merger, substantially to the effect that, on the basis of facts, representations and assumptions set forth or referred to in the opinion (including factual representations contained in certificates of officers of Mid Penn and 1st Colonial) which are consistent with the state of facts existing as of the effective date of the merger, the merger will be treated for United States federal income tax purposes as a reorganization within the meaning of Section 368(a) of the Code. The tax opinions to be delivered in connection with the merger represent each counsel’s best legal judgment; however, such opinions are not binding on the IRS or the courts, and neither Mid Penn nor 1st Colonial intends to request a ruling from the IRS with respect to the United States federal income tax consequences of the merger. Consequently, no assurance can be given that the IRS will not assert, or that a court would not sustain, a position contrary to any of those set forth below. In addition, if any of the facts, representations or assumptions upon which

TABLE OF CONTENTS

such opinions are based is inconsistent with the actual facts, the United States federal income tax consequences of the merger could be adversely affected.

Assuming that the merger will be treated as a reorganization within the meaning of Section 368(a) of the Code, the discussion below sets forth the opinions of Holland & Knight and Stradley Ronon, insofar as such discussion constitutes statements of United States federal income tax law or legal conclusions, as to the material United States federal income tax consequences of the merger to 1st Colonial shareholders:

•

a U.S. holder of 1st Colonial common stock receiving solely cash in exchange for such 1st Colonial common stock generally will recognize gain and loss in an amount equal to the difference between the amount of cash received and the U.S. holder’s aggregate tax basis in the shares of 1st Colonial common stock surrendered;

•

gain (but not loss) will be recognized by U.S. holders of 1st Colonial common stock who receive both shares of Mid Penn common stock and cash in exchange for shares of 1st Colonial common stock pursuant to the merger, in an amount equal to the lesser of (1) the amount by which the sum of the fair market value of the Mid Penn common stock and cash received by a U.S. holder of 1st Colonial common stock exceeds such U.S. holder’s basis in its 1st Colonial common stock and (2) the amount of cash received by such U.S. holder of 1st Colonial common stock (except with respect to U.S. holders who receive cash only or cash instead of a fractional share of Mid Penn common stock, which is discussed below under “ Receipt of Cash Consideration Only and Cash Received Instead of a Fractional Share of Mid Penn Common Stock ”);

•

the aggregate basis of the Mid Penn common stock received by a U.S. holder of 1st Colonial common stock in the merger (including the basis of fractional shares of Mid Penn common stock deemed received, prior to their deemed redemption as described below) will be the same as the aggregate basis of 1st Colonial common stock for which it is exchanged, decreased by the amount of cash (if any) received in the merger (other than cash received in lieu of fractional share interests in Mid Penn common stock), and increased by the amount of gain recognized on the exchange (other than gain recognized with respect to cash received in lieu of fractional share interests in Mid Penn common stock, as discussed below under “ Receipt of Cash Consideration Only and Cash Received Instead of a Fractional Share of Mid Penn Common Stock ”); and

•

the holding period of Mid Penn common stock received in exchange for shares of 1st Colonial common stock (including fractional shares of Mid Penn common stock deemed received and redeemed as described below) will include the holding period of 1st Colonial common stock for which it is exchanged.

If a U.S. holder of 1st Colonial common stock acquired different blocks of 1st Colonial common stock at different times or at different prices, any gain or loss will be determined separately with respect to each block of 1st Colonial common stock, and the cash and shares of Mid Penn common stock received will be allocated pro rata to each such block of stock. In computing the amount of gain realized, if any, a U.S. holder of 1st Colonial common stock may not offset a loss realized on one block of shares against the gain realized on another block of shares. U.S. holders should consult their tax advisors with regard to identifying the bases and holding periods of the particular shares of Mid Penn common stock received in the merger.

At the time that a U.S. holder makes a cash or stock election pursuant to the terms of the merger agreement, such U.S. holder will not know whether, and to what extent, the proration provisions of the merger agreement might alter the mix of consideration such U.S. holder will receive. As a result, the United States federal income tax consequences to such U.S. holder will not be ascertainable until such U.S. holder knows the precise amount of cash and/or Mid Penn common shares that such U.S. holder will receive in the merger.

Taxation of Capital Gain

Except as described under “ Additional Considerations — Recharacterization of Gain as a Dividend ” below, gain that U.S. holders of 1st Colonial common stock recognize in connection with the merger generally will constitute capital gain and will constitute long-term capital gain if such U.S. holders have held (or are treated as having held) their 1st Colonial common stock for more than one year as of the date of

TABLE OF CONTENTS

the merger. For U.S. holders of 1st Colonial common stock that are non-corporate holders, long-term capital gain is generally taxed at preferential rates. U.S. holders of 1st Colonial common stock are urged to consult with their own tax advisors about whether the United States federal income tax rate on long-term capital gain may be applicable to them.

Additional Considerations-Recharacterization of Gain as a Dividend

In limited circumstances, all or part of the gain that a particular U.S. holder of 1st Colonial common stock recognizes could be treated as dividend income rather than capital gain. Because the possibility of dividend treatment depends primarily upon the particular circumstances of a holder of 1st Colonial common stock, including the application of certain constructive ownership rules, U.S. holders of 1st Colonial common stock should consult their own tax advisor regarding the potential tax consequences of the merger to them.

Receipt of Cash Consideration Only and Cash Received Instead of a Fractional Share of Mid Penn Common Stock

A U.S. holder of 1st Colonial common stock who receives the entirety of its consideration in the form of cash will generally recognize gain or loss equal to the difference between the amount of cash received and its tax basis in its 1st Colonial common stock. In addition, a U.S. holder of 1st Colonial common stock who receives cash in lieu of a fractional share of Mid Penn common stock will be treated as having received the fractional share pursuant to the merger and then as having exchanged the fractional share for cash in a redemption by Mid Penn. As a result, such U.S. holder of 1st Colonial common stock will generally recognize gain or loss equal to the difference between the amount of cash received and its tax basis in its fractional share interest as set forth above. The gain or loss recognized by the U.S. holders described in this paragraph will generally be capital gain or loss, and will be long-term capital gain or loss if, as of the effective date of the merger, the U.S. holder’s holding period for the relevant shares is greater than one (1) year. The deductibility of capital losses is subject to limitations.

Information Reporting and Backup Withholding

Backup withholding will generally apply to merger consideration that includes cash if the exchanging 1st Colonial shareholder fails to properly certify that it is not subject to backup withholding, generally on IRS Form W-9. Certain holders, including, among others, United States corporations, are not subject to backup withholding, but they may still need to furnish an IRS Form W-9 or otherwise establish an exemption. Any amounts withheld from payments to a 1st Colonial shareholder under the backup withholding rules are not additional taxes and will be allowed as a refund or credit against the shareholder’s United States federal income tax liability, provided that the required information is timely furnished to the IRS.

A U.S. holder receiving shares of Mid Penn common stock as a result of the merger will be required to retain records pertaining to the merger. Each U.S. holder that is required to file a U.S. federal income tax return and is a “significant holder” will be required to file a statement with the holder’s U.S. federal income tax return setting forth the holder’s basis (determined immediately before the exchange) in the 1st Colonial common stock surrendered and the fair market value (determined immediately before the exchange) of the 1st Colonial common stock that is exchanged by such holder pursuant to the merger. A “significant holder” is a U.S. holder that receives shares of Mid Penn common stock in the merger and that, immediately before the merger, owned at least five percent (5%) of the outstanding stock of Mid Penn (by vote or value) or securities of Mid Penn with a tax basis of $1 million or more.

Tax matters are very complicated, and the tax consequences of the merger to each holder of 1st Colonial common stock will depend on the facts of that shareholder’s particular situation. The discussion set forth above does not address all United States federal income tax consequences that may be relevant to a particular holder of 1st Colonial common stock and may not be applicable to holders in special situations. Holders of 1st Colonial common stock are urged to consult their own tax advisors regarding the specific tax consequences of the merger, including those arising under the United States federal estate or gift tax rules, or under the laws of any state, local, foreign or other taxing jurisdiction. Further, such discussion does not address tax consequences that may arise with respect to Mid Penn by reason of any actions taken or events occurring subsequent to the merger.

TABLE OF CONTENTS

DESCRIPTION OF CAPITAL STOCK OF MID PENN

As a result of the merger, 1st Colonial shareholders who receive shares of Mid Penn common stock in the merger will become shareholders of Mid Penn. Your rights as a shareholder of Mid Penn will be governed by the PBCL, the Mid Penn articles, and the Mid Penn bylaws. The following briefly summarizes the material terms of Mid Penn’s capital stock, including the Mid Penn common stock to be issued in the merger. We urge you to read the applicable provisions of Pennsylvania law, the Mid Penn articles and the Mid Penn bylaws and federal law governing bank holding companies carefully and in their entirety.

General

As of the date of this proxy statement/prospectus, Mid Penn has 50,000,000 shares of authorized capital stock, consisting of 40,000,000 shares of common stock, $1.00 par value, and 10,000,000 shares of preferred stock, $1.00 par value. Within the limits of applicable law and the listing rules of Nasdaq, these shares are available to be issued, without prior shareholder approval. As of the date of this proxy statement/ prospectus, there were [ ] shares of Mid Penn common stock and no shares of Mid Penn preferred stock issued and outstanding and [ ] shares of Mid Penn common stock reserved for issuance under various stock-based equity plans and Mid Penn’s Employee Stock Purchase Plan and 401(k) Retirement Savings Plan. All outstanding shares of Mid Penn capital stock are fully paid and non-assessable.

Common Stock

Voting Rights. Each outstanding share of Mid Penn common stock entitles the holder to one vote on all matters submitted to a vote of Mid Penn shareholders, including the election of directors. Unless a larger vote is required by law, the Mid Penn articles or the Mid Penn bylaws, when a quorum is present at a meeting of shareholders, a majority of the votes properly cast upon any question other than the election of directors will decide the question. A plurality of the votes properly cast for the election of a person to serve as a director will elect such person.

TABLE OF CONTENTS

1ST COLONIAL PROPOSALS

PROPOSAL 1: 1ST COLONIAL MERGER PROPOSAL

At the 1st Colonial special meeting, 1st Colonial shareholders will be asked to approve and adopt the merger agreement. 1st Colonial shareholders should read this proxy statement/prospectus carefully and in its entirety, including the annexes and exhibits, for more detailed information concerning the merger agreement and the merger. A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A .

After careful consideration, the 1st Colonial board of directors has unanimously (i) adopted and approved the merger agreement and the transactions contemplated thereby, (ii) determined the merger agreement and the merger to be advisable and in the best interests of 1st Colonial and 1st Colonial shareholders and (iii) declared it advisable to enter into the merger agreement. See the section entitled “ The Merger — 1st Colonial’s Reasons for the Merger; Recommendation of the 1st Colonial Board of Directors ” included elsewhere in this proxy statement/prospectus for a more detailed discussion of the 1st Colonial board of directors’ recommendation.

The approval and adoption of the 1st Colonial merger proposal by 1st Colonial shareholders is a condition to completion of the merger.

The 1st Colonial board of directors unanimously recommends that 1st Colonial shareholders vote “FOR” the 1st Colonial merger proposal.

PROPOSAL 2: 1ST COLONIAL ADJOURNMENT PROPOSAL

The 1st Colonial special meeting may be adjourned to another time, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the 1st Colonial special meeting to adopt and approve the 1st Colonial merger proposal or to ensure that any supplement or amendment to this proxy statement/prospectus is timely provided to 1st Colonial shareholders.

If, at the 1st Colonial special meeting, the number of shares of 1st Colonial common stock present or represented and voting in favor of the 1st Colonial merger proposal is insufficient to adopt and approve the 1st Colonial merger proposal, 1st Colonial intends to move to adjourn the 1st Colonial special meeting in order to enable the 1st Colonial board of directors to solicit additional proxies for the adoption and approval of the 1st Colonial merger proposal. In that event, 1st Colonial will ask 1st Colonial shareholders to vote upon the 1st Colonial adjournment proposal, but not the 1st Colonial merger proposal.

In this proposal, 1st Colonial is asking 1st Colonial shareholders to authorize the holder of any proxy solicited by the 1st Colonial board of directors, on a discretionary basis, to vote in favor of adjourning the 1st Colonial special meeting to another time and place for the purpose of soliciting additional proxies, including the solicitation of proxies from 1st Colonial shareholders who have previously voted, if a quorum is not present, or if there are insufficient votes at the time of the 1st Colonial special meeting to adopt and approve the 1st Colonial merger proposal or if necessary or appropriate to ensure that any supplement or amendment to the accompanying proxy statement/prospectus is timely provided to holders of 1st Colonial common stock. Pursuant to the 1st Colonial bylaws, the 1st Colonial special meeting may be adjourned without further notice being given unless a new record date for such adjourned meeting is, or is required by law or the 1st Colonial bylaws to be fixed.

The approval of the 1st Colonial adjournment proposal by 1st Colonial shareholders is not a condition to completion of the merger.

The 1st Colonial board of directors unanimously recommends that 1st Colonial shareholders vote “FOR” the 1st Colonial adjournment proposal.

	DIRECTOR QUALIFICATIONS, ELIGIBILITY AND MANDATORY RETIREMENT
	Each 1st Colonial director must own common or preferred stock of the 1st Colonial with an aggregate par, fair market, or equity value of $1,000.

Mid Penn maintains a mandatory retirement policy. Upon reaching the age of seventy-two (72), a Mid Penn director will hold office until the following annual meeting of shareholders at which time such director will retire from the Mid Penn board of directors.

	ANTI-TAKEOVER PROVISIONS AND OTHER SHAREHOLDER PROTECTIONS
	Under the 1st Colonial articles, any merger, consolidation, liquidation, dissolution, or sale of all or substantially all of 1st Colonial’s assets must be approved by the affirmative vote of shareholders entitled to cast at least 80% of the votes which all shareholders are entitled to cast. If any class of shares is entitled to vote as a separate class, approval also requires the affirmative vote of shareholders entitled to cast at least a majority of the votes entitled to be cast by the outstanding shares of that class. If any of the foregoing transactions are approved in advance by sixty-six and two-thirds percent (66-2/3%) or more of the members of the 1st Colonial board of directors, at a meeting duly called and held then pursuant to Pennsylvania law, the transaction must be adopted by the affirmative vote of a majority of the votes cast at such meeting. The 1st Colonial articles include a requirement that a twenty-five (25%) beneficial owner make a follow-on offer to purchase all voting shares at the highest price paid in prior twelve (12) months or at fair market value; except when the acquisition of the twenty-five (25%) beneficial owner is approved in advance by eighty percent (80%) or more of the 1st Colonial board of directors.			Under the Mid Penn articles, any merger, consolidation, liquidation or dissolution of Mid Penn or any action that would result in the sale or other disposition of all or substantially all of the assets of Mid Penn must be approved by the affirmative vote of the holders of at least eighty percent (80%) of the outstanding shares of common stock, unless approved in advance by at least eighty percent (80%) of the board of directors, in which case such transaction requires shareholder approval to the extent required by the PBCL or the rules of any national securities exchange on which shares of Mid Penn common stock are traded. The board may, if it deems advisable, oppose a tender or other offer for Mid Penn’s securities, whether the offer is in cash or in the securities of a corporation or otherwise. When considering whether to oppose an offer, the board may, but is not legally obligated to, consider whether the offer price is acceptable based on the historical and present operating results or financial condition of the corporation; whether a more favorable price could be obtained for Mid Penn’s securities in the future; the social and economic effects of the offer or transaction on Mid Penn and any of its subsidiaries, employees, depositors, loan and other customers, creditors, shareholders and other elements of the communities in which Mid Penn and any of its subsidiaries operate or are located; the reputation and business practice of the offeror and its management and affiliates as they would affect the shareholders, employees, depositors and customers of the corporation and its subsidiaries and the future value of the corporation’s stock; the value of the securities (if any) which the offeror is offering in exchange for Mid Penn’s securities, based on the analysis of the worth of the corporation or other entity whose securities are being offered; the business and financial conditions and earnings prospects of the offeror, including, but not limited to, debt service and other existing or likely financial obligations of the offeror, and the possible effect of such

Employees and agents of 1st Colonial who are not directors or officers may be indemnified at 1st Colonial’s discretion. Directors are not personally liable for monetary damages to the extent the director did not breach duties and the breach does not constitute self-dealing, willful misconduct, recklessness, or breach of applicable law/regulations.			Under the Mid Penn bylaws, to the fullest extent authorized or permitted by applicable law, Mid Penn will indemnify any director, officer, employee, or agent of Mid Penn who was or is a party or is threatened to be made a party to any threatened, pending, or completed action, suit or proceeding, whether civil, criminal, administrative, or investigative, or is or was serving at the request of Mid Penn as a director, officer, employee, or agent of another corporation, partnership, joint venture, trust, or other enterprise, against expenses, amounts paid in settlement, judgments, and fines actually and reasonably incurred by those persons in connection with any action suit or proceeding. No indemnification will be made in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. The provision does not affect a director’s responsibility or liability under any criminal statute or liability for payment of taxes.
	AMENDMENTS TO THE ARTICLES OF INCORPORATION AND BYLAWS
	1st Colonial may amend, alter, change or repeal any provision contained in the 1st Colonial articles in the manner prescribed by statute and all rights conferred upon shareholders and directors are granted subject to this reservation; provided, however, that Articles Sixth through Fifteenth of the 1st Colonial articles may not be repealed, altered or amendment unless approved by either (1) the affirmative vote of shareholders of the 1st Colonial entitled to cast at least eighty percent (80%) of the votes which all shareholders of 1st Colonial are then entitled to cast or (2) the affirmative vote of eighty percent (80%) of the members of the 1st Colonial board of directors and the affirmative vote of shareholders of 1st Colonial entitled to cast at least a majority of the votes which all shareholders of 1st Colonial are then entitled to cast.

APPRAISAL RIGHTS

In the discussion of dissenters’ rights, the term “fair value” means the value of a share of 1st Colonial common stock immediately before the day of the effective date of the merger, taking into account all relevant factors, but excluding any appreciation or depreciation in anticipation of the merger. Before the effective date of the merger, 1st Colonial shareholders should send any written notice or demand required in order to exercise dissenters’ rights to 1st Colonial Bancorp, Inc., 1000 Atrium Way, Suite 200, Mount Laurel, New Jersey 08054 (Attn: Mary Kay Shea, Secretary of 1st Colonial Bancorp, Inc.).

After the effective date of the merger, all dissenters should send any correspondence to Mid Penn Bancorp, Inc., 2407 Park Drive, Harrisburg, Pennsylvania 17110 (Attn: Investor Relations).

Notice of Intention to Dissent

If you wish to dissent from the merger, you must do the following:

•

Prior to the vote on the merger agreement at the 1st Colonial special meeting, file with 1st Colonial a written notice of your intention to demand payment of the fair value of your shares of common stock if the merger is completed;

•

Make no change in your beneficial ownership of the common stock with respect to which you are dissenting from the date you give notice of your intention to demand fair value of your shares through the day of the merger; and

•

Not vote your shares of common stock with respect to which you are dissenting in favor of adoption of the merger agreement at the special meeting.

Simply voting against the proposed merger, whether in person or by proxy, will not constitute notice of your intention to dissent. Further, if you submit a proxy, but do not indicate how you wish to vote, your shares will be voted in favor of the adoption and approval of the merger, and your right to dissent will be lost.

Notice to Demand Payment

If the merger is adopted by the required vote of 1st Colonial shareholders, 1st Colonial will mail a notice to all those dissenting shareholders who gave due notice of their intention to demand payment of the fair value of their shares and who did not vote to adopt the merger agreement. The notice will state where and when dissenting shareholders must deliver a written demand for payment and where such dissenting shareholder must deposit certificates for the shares of common stock for which they dissented in order to obtain payment. The notice will include a form for demanding payment and a copy of the relevant provisions of Pennsylvania law. The time set for receipt of the demand for payment and deposit of stock certificates will be not less than thirty (30) days from the date of mailing of the notice.

Failure to Comply with Required Steps to Dissent

You must take each step in the indicated order and in strict compliance with Pennsylvania law in order to maintain your dissenters’ rights. If you fail to follow these steps, you will lose the right to dissent, and you will receive the same merger consideration as shareholders who do not dissent.

Payment of Fair Value of Shares

Promptly after the effective date of the merger, or upon timely receipt of demand for payment if the closing of the merger has already taken place, Mid Penn will send each dissenting shareholder who has

TABLE OF CONTENTS

deposited his, her or its stock certificates, the amount that Mid Penn estimates to be the fair value of the common stock held by such dissenting shareholder. The remittance or notice will be accompanied by:

•

a closing balance sheet and statement of income of 1st Colonial for the fiscal year ending not more than sixteen (16) months before the date of remittance or notice, together with the latest available interim financial statements;

•

a statement of Mid Penn’s estimate of the fair value of 1st Colonial’s common stock; and

•

a notice of the right of the dissenting shareholder to demand supplemental payment, accompanied by a copy of the relevant provisions of Pennsylvania law.

Estimate by Dissenting Shareholder of Fair Value of Shares

If a dissenting shareholder believes that the amount stated or remitted by Mid Penn is less than the fair value of their common stock, the dissenting shareholder must send its estimate of the fair value (deemed a demand for the deficiency) of such common stock to Mid Penn within thirty (30) days after Mid Penn mails its remittance. If the dissenting shareholder does not file its estimated fair value within thirty (30) days after the mailing by Mid Penn of its remittance, the dissenting shareholder will be entitled to no more than the amount remitted by Mid Penn.

Valuation Proceedings

If any demands for payment remain unsettled within sixty (60) days after the latest to occur of:

•

the effective date of the merger;

•

timely receipt by 1st Colonial of any demands for payment; or

•

timely receipt by Mid Penn of any estimates by dissenters of the fair value,

•

then Mid Penn may file an application in the Court of Common Pleas requesting that the court determine the fair value of the common stock. If this happens, all dissenting shareholders whose demands have not been settled, no matter where they reside, will become parties to the proceeding. In addition, a copy of the application will be delivered to each dissenting shareholder.

If Mid Penn were to fail to file the application, then any dissenting shareholder, on behalf of all dissenting shareholders who have made a demand and who have not settled their claim against Mid Penn, may file an application in the name of Mid Penn at any time within the thirty (30)-day period after the expiration of the sixty (60)-day period and request that the Court of Common Pleas determine the fair value of the shares. The fair value determined by the Court of Common Pleas may, but need not, equal the dissenting shareholders’ estimates of fair value. If no dissenter files an application, then each dissenting shareholder entitled to do so shall be paid no more than Mid Penn’s estimate of the fair value of their common stock and may bring an action to recover any amount not previously remitted, plus interest at a rate the Court of Common Pleas finds fair and equitable.

Mid Penn intends to negotiate in good faith with any dissenting shareholder. If, after negotiation, a claim cannot be settled, then Mid Penn will file an application requesting that the fair value of the 1st Colonial common stock, as the case may be, be determined by the Court of Common Pleas.

Cost and Expenses

The costs and expenses of any valuation proceedings performed by the Court of Common Pleas, including the reasonable compensation and expenses of any appraiser appointed by such court to recommend a decision on the issue of fair value, will be determined by such court and assessed against Mid Penn, except that any part of the costs and expenses may be apportioned and assessed by such court against any or all of the dissenting shareholders who are parties and whose action in demanding supplemental payment is dilatory, obdurate, arbitrary, vexatious or in bad faith, in the opinion of such court.

1st Colonial shareholders wishing to exercise their dissenters’ rights should consult their own counsel to ensure that they fully and properly comply with applicable requirements.

TABLE OF CONTENTS

FAILURE TO FOLLOW THE PROCEDURES SET FORTH IN SUBCHAPTER D OF CHAPTER 15 OF THE PBCL REGARDING DISSENTERS’ RIGHTS WILL CONSTITUTE A WAIVER OF THOSE RIGHTS. SHAREHOLDERS MAY WISH TO CONSULT INDEPENDENT COUNSEL BEFORE EXERCISING DISSENTERS’ RIGHTS.

Income Tax Consequences

The exercise of dissenters’ rights may result in taxable income to you. Neither Mid Penn nor 1st Colonial has obtained a tax opinion regarding the tax consequences of a shareholder exercising their dissenters’ rights. Accordingly, those who wish to exercise their dissenters’ rights should consult their own tax advisors regarding the tax consequences of such an election. See “ Material United States Federal Income Tax Consequences of the Merger ” on page 71 .

At the Effective Time, by virtue of the Merger and without any action on the part of Mid Penn, 1st Colonial or the holders of any of the shares of 1st Colonial Common Stock, the Merger shall be effected in accordance with the following terms:

(a) Each share of Mid Penn Common Stock that is issued and outstanding immediately prior to the Effective Time shall remain issued and outstanding following the Effective Time and shall be unchanged by the Merger.

(b) All shares of 1st Colonial Common Stock held in the treasury of 1st Colonial (“ Treasury Stock ”), and each share of 1st Colonial Common Stock owned by Mid Penn immediately prior to the Effective Time (if any) (other than shares held in a fiduciary capacity or in connection with debts previously contracted) (“ Mid Penn Owned Shares ”) shall, at the Effective Time, cease to exist, and the

A-11

TABLE OF CONTENTS

Certificates for such shares shall be cancelled as promptly as practicable thereafter, and no payment or distribution shall be made in consideration therefor.

(c) Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any Person, each share of 1st Colonial Common Stock (excluding Treasury Stock, Mid Penn Owned Shares and Dissenting Shares pursuant to Section 3.3 ) issued and outstanding immediately prior to the Effective Time shall be converted into the right to receive, without interest, at the election of the holder thereof and in accordance with the procedures set forth in Section 3.2 and subject to Section 3.4 and Section 3.1(f) and (h), the following:

(1) For each share of 1 st Colonial Common Stock with respect to which an election to receive cash has been effectively made and not revoked or lost, pursuant to Section 3.2 (a “ Cash Election ”), the right to receive in cash from Mid Penn, without interest, an amount equal to $18.50 (the “ Cash Consideration ”)(collectively, “ Cash Election Shares ”);

(2) for each share of 1 st Colonial Common Stock with respect to which an election to receive Mid Penn Common Stock has been effectively made and not revoked or lost, pursuant to Section 3.2 (a “ Stock Election ”), the right to receive from Mid Penn the number of shares of Mid Penn Common Stock equal to the Exchange Ratio (the “ Stock Consideration ”) (collectively, the “ Stock Election Shares ”); and

(3) for each share of 1 st Colonial Common Stock other than shares as to which a Cash Election or a Stock Election has been effectively made and not revoked or lost, pursuant to Section 3.2 (collectively, “ Non-Election Shares ”), the right to receive such Stock Consideration or Cash Consideration as determined in accordance with Section 3.4.

For purposes of this Agreement: (x) “ Exchange Ratio ” means 0.6945 of Mid Penn Common Stock; and (y) Cash Consideration and Stock Consideration are sometimes referred to herein collectively as the “ Merger Consideration .”

(d) After the Effective Time, shares of 1st Colonial Common Stock shall be no longer outstanding and shall automatically be cancelled and shall cease to exist, and shall represent thereafter by operation of this section only the right to receive the Merger Consideration as set forth in this Article III and, if applicable, any dividends or distributions with respect thereto or any dividends or distributions with a record date prior to the Effective Time that were declared or made by 1st Colonial on such shares of 1st Colonial Common Stock in accordance with this Agreement on or prior to the Effective Time.

(e) The number of shares of 1st Colonial Common Stock to be converted into the right to receive the Stock Consideration shall be equal to sixty percent (60%) of the number of shares of 1st Colonial Common Stock outstanding immediately prior to the Effective Time and the number of shares of 1st Colonial Common Stock to be converted into the right to receive the Cash Consideration shall be equal to forty percent (40%) of the number of shares of 1st Colonial Common Stock outstanding immediately prior to the Effective Time. In the event that the foregoing clauses of this Section 3.1 and the election procedures set forth in Section 3.2 result in less or more than such percentages, then pro rata adjustments will be made in accordance with the procedures set forth in Section 3.4 .

(f) Notwithstanding Section 3.1(e), if either of the tax opinions referred to in Section 9.1(e) cannot be rendered (as reasonably determined, in each case, by the counsel charged with giving such opinion) as a result of the Merger potentially failing to satisfy the “continuity of interest” requirements under applicable federal income tax principles relating to reorganizations under Section 368(a) of the Code, then Mid Penn shall reduce the Cash Consideration and increase the Stock Consideration to the minimum extent necessary to enable the relevant tax opinions to be rendered.

(g) Treatment of 1st Colonial Equity Awards.

(1) At the Effective Time, each option granted by 1st Colonial to purchase shares of 1st Colonial Common Stock (the “ 1st Colonial Option ”), whether vested or unvested, that is outstanding and unexercised immediately prior to the Effective Time shall be cancelled and converted into the right to receive a single lump sum cash payment by Mid Penn, equal to the

A-12

TABLE OF CONTENTS

product of (i) the number of shares of 1st Colonial Common Stock subject to such 1st Colonial Option immediately prior to the Effective Time, and (ii) the excess, if any, of (A) $18.50 over (B) the exercise price per share of such 1st Colonial Option (the “ Option Merger Consideration ”), less any applicable Taxes required to be withheld with respect to such payment in accordance with Section 3.2(e) and less all applicable payroll deductions. If the exercise price per share of any such 1st Colonial Option is equal to or greater than $18.50, such 1st Colonial Option shall be canceled at the Effective Time without any cash payment being made in respect thereof. The Option Merger Consideration (less all applicable payroll deductions and Tax withholdings) shall be paid on the first or second payroll date after the Closing Date. Ten (10) days prior to the Closing Date, 1st Colonial shall accelerate the vesting of all unvested 1st Colonial Options that are then outstanding, and shall provide the holders of all 1st Colonial Options with notice of their right to exercise such 1st Colonial Options at any time prior to the Effective Time and the consequences of not exercising their 1st Colonial Options prior to the Effective Time.

(2) 1st Colonial shall take all actions necessary, such that (i) within five days prior to the Closing Date, (a) any vesting restrictions on each then outstanding restricted stock unit granted by 1st Colonial (a “ 1st Colonial RSU ”) under a 1st Colonial Stock Plan shall automatically lapse, (b) each then outstanding 1st Colonial RSU shall be cancelled at the time of such acceleration and settled (with one share of 1st Colonial Common Stock being issued in settlement of each 1st Colonial RSU then being settled), provided, that the number of shares of 1st Colonial Common Stock issued in settlement of any such 1st Colonial RSU shall be net of any applicable Tax withholding obligations in accordance with appliable law and (c) all accrued but unpaid dividend equivalents on the 1st Colonial RSUs settled pursuant to the preceding clause (b) have been paid to the holder of such 1st Colonial RSU (less all applicable Tax withholdings and payroll deductions) and (ii) on the Closing Date, no 1st Colonial RSUs shall be outstanding.

(3) At or prior to the Effective Time, 1st Colonial, the 1st Colonial Board of Directors and/or its compensation committee, as applicable, shall adopt any resolutions, effective and contingent on the Closing, and take any actions that are necessary to (i) effectuate the provisions of this Section 3.1(g) , (ii) terminate the 1st Colonial Stock Plans effective as of the Effective Time and (iii) ensure that following the Effective Time, no Person by virtue of holding any 1st Colonial RSUs or any 1st Colonial Option, shall have any rights with respect thereto other than as specifically provided in this Section 3.1(g) .

(h) In the event Mid Penn changes the number of shares of Mid Penn Common Stock issued and outstanding between the date hereof and the Effective Time as a result of a stock split, stock dividend, extraordinary dividend, recapitalization, reclassification, split up, readjustment or similar capitalization change and the record date therefor shall be prior to the Effective Time, the Merger Consideration shall be proportionately adjusted to give 1st Colonial and the holders of 1st Colonial Common Stock the same economic effect as contemplated by this Agreement prior to such events. In addition, in the event Mid Penn enters into an agreement pursuant to which shares of Mid Penn Common Stock would be converted into shares or other securities or obligations of another corporation, proper provision shall be made in such agreement so that each holder of 1st Colonial Common Stock entitled to receive shares of Mid Penn Common Stock in the Merger shall be entitled to receive such number of shares or other securities or amount or obligations of such other corporation as such shareholder would be entitled to receive if the Effective Time had occurred immediately prior to the happening of such event.

(i) Notwithstanding anything to the contrary contained herein, no certificates or scrip representing fractional shares of Mid Penn Common Stock shall be issued upon the surrender for exchange of Certificates, no dividend or distribution with respect to Mid Penn Common Stock shall be payable on or with respect to any fractional share interest, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of Mid Penn. In lieu of the issuance of any such fractional share, Mid Penn shall pay to each former holder of 1st Colonial Common Stock who otherwise would be entitled to receive a fractional share of Mid Penn Common Stock, an amount in cash, rounded to the nearest cent and without interest, equal to the product of the fractional share interest to which such holder would otherwise be entitled by $18.50. For purposes of

A-13

TABLE OF CONTENTS

determining any fractional share interest, all shares of 1st Colonial Common Stock owned by a 1st Colonial shareholder shall be combined so as to calculate the maximum number of whole shares of Mid Penn Common Stock issuable to such 1st Colonial shareholder. The parties acknowledge that the payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares. This Section 3.1(g) shall apply mutatis mutandis to Section 3.1(e)(2) .

3.2. Procedures for Exchange of 1st Colonial Common Stock .

f. All Elections shall be revoked automatically if the Exchange Agent is notified in writing by Mid Penn or 1st Colonial that this Agreement has been terminated in accordance with Article X.

No dividends or other distributions declared after the Effective Time with respect to Mid Penn Common Stock shall be paid to the holder of any unsurrendered Certificate until the holder thereof shall surrender such Certificate in accordance with this Section 3.2 . After the surrender of a Certificate in accordance with this Section 3.2 , the record holder thereof shall be entitled to receive, without any interest thereon, any such dividends or other distributions with a record date after the Effective Time, which theretofore had become payable with respect to shares of Mid Penn Common Stock represented by such Certificate.

(c) Surrender by Persons Other than Record Holders . If the Person surrendering a Certificate and signing the accompanying Letter of Transmittal is not the record holder thereof, then it shall be a condition of the payment of the Merger Consideration that: (i) such Certificate is properly endorsed to such Person or is accompanied by appropriate stock powers, in either case signed exactly as the name of the record holder appears on such Certificate, and is otherwise in proper form for transfer, or is accompanied by appropriate evidence of the authority of the Person surrendering such Certificate and signing the Letter of Transmittal to do so on behalf of the record holder; and (ii) the Person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other taxes required by reason of the payment to a Person other than the registered holder of the Certificate surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such tax has been paid or is not payable.

To the extent that such amounts are so properly withheld, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the Person in respect of whom such deduction and withholding were made.

(f) Return of Exchange Fund . At any time following the twelve (12) month period after the Effective Time, Mid Penn shall be entitled to require the Exchange Agent to deliver to it any portions of the Exchange Fund that had been made available to the Exchange Agent and not disbursed to holders of Certificates (including, without limitation, all interest and other income received by the Exchange Agent in respect of all funds made available to it), and thereafter such holders shall be entitled to look to Mid Penn (subject to abandoned property, escheat and other similar laws) with respect to any Merger Consideration that may be payable upon due surrender of the Certificates held by them. Notwithstanding the foregoing, neither Mid Penn nor the Exchange Agent shall be liable to any holder of a Certificate for any Merger Consideration delivered in respect of such Certificate to a public official pursuant to applicable abandoned property, escheat or other similar law.

Each outstanding share of 1st Colonial Common Stock, the holder of which has perfected his, her or its right to dissent under Subchapter D of Chapter 15 of the PBCL and has not effectively withdrawn or lost such right as of the Effective Time (the “ Dissenting Shares ”), shall not be converted into or represent a right to receive the Merger Consideration hereunder, and the holder thereof shall be entitled only to such rights as are granted by Subchapter D of Chapter 15 of the PBCL. 1st Colonial shall give Mid Penn prompt notice upon receipt by 1st Colonial of any such demands for payment of the fair value of such shares of 1st Colonial Common Stock and of withdrawals of such notice and any other related communications (any shareholder duly making such demand being hereinafter called a “ Dissenting Shareholder ”), and Mid Penn shall have the right to participate in all discussions, negotiations and proceedings with respect to any such demands. 1st Colonial shall not, except with the prior written consent of Mid Penn, voluntarily make any payment with respect to, or settle or offer to settle, any such demand for payment, or waive any failure to timely deliver a written demand for appraisal or the taking of any other action by such Dissenting Shareholder as may be necessary to perfect appraisal rights under the PBCL. Any payments made in respect of Dissenting Shares shall be made by Mid Penn. If any Dissenting Shareholder withdraws or loses (through failure to perfect or otherwise) his, her, or it’s right to such payment at or before the Effective Time, such holder’s shares of 1st Colonial Common Stock shall no longer be “Dissenting Shares”, and shall be converted into a right to receive the Merger Consideration in accordance with the

applicable provisions of this Agreement. If such holder withdraws or loses (through failure to perfect or otherwise) his, her or it’s right to such payment after the Effective Time, each share of 1st Colonial Common Stock of such holder shall be entitled to receive the Merger Consideration.

3.4. Proration.

(a) Notwithstanding any other provision contained in this Agreement, the total number of shares of 1 st Colonial Common Stock to be entitled to receive the Cash Consideration pursuant to Section 3.1(c)(1) shall be equal to the product (rounded down to the nearest whole share) of (i) 0.40 and (ii) the total number of shares of 1 st Colonial Common Stock issued and outstanding immediately prior to the Effective Time (excluding the shares of 1 st Colonial Common Stock to be cancelled as provided in Section 3.1(b)) (the “ Cash Conversion Number ”). All other shares of 1 st Colonial Common Stock (excluding the shares of 1 st Colonial Common Stock to be cancelled as provided in Section 3.1(b)) shall be converted into the right to receive the Stock Consideration.

(b) Promptly (and in any event no later than five (5) business days) after the Effective Time, Mid Penn shall cause the Exchange Agent to effect the allocation among Holders (as defined below) of rights to receive the Cash Consideration and the Stock Consideration as follows:

(i) If the aggregate number of shares of 1 st Colonial Common Stock (including shares of 1st Colonial Common Stock issued prior to the Effective Time for 1st Colonial Option exercises and the vesting of 1st Colonial RSUs) with respect to which Cash Elections shall have been made (the “ Cash Election Number ”) exceeds the Cash Conversion Number, then all Stock Election Shares and all Non-Election Shares shall be converted into the right to receive the Stock Consideration, and Cash Election Shares of each Holder will be converted into the right to receive the Cash Consideration in respect of that number of Cash Election Shares equal to the product obtained by multiplying (A) the number of Cash Election Shares held by such Holder by (B) a fraction, the numerator of which is the Cash Conversion Number and the denominator of which is the Cash Election Number (with the Exchange Agent to determine whether fractions of Cash Election Shares shall be rounded up or down), with the remaining number of such Holder’s Cash Election Shares being converted into the right to receive the Stock Consideration; and

(ii) If the Cash Election Number is less than the Cash Conversion Number (the amount by which the Cash Conversion Number exceeds the Cash Election Number being referred to herein as the “ Shortfall Number ”), then all Cash Election Shares shall be converted into the right to receive the Cash Consideration and the Non-Election Shares and Stock Election Shares shall be treated in the following manner:

(A) If the Shortfall Number is less than or equal to the number of Non-Election Shares, then all Stock Election Shares shall be converted into the right to receive the Stock Consideration, and the Non-Election Shares of each holder thereof shall be converted into the right to receive the Cash Consideration in respect of that number of Non-Election Shares equal to the product obtained by multiplying (x) the number of Non-Election Shares held by such Holder by (y) a fraction, the numerator of which is the Shortfall Number and the denominator of which is the total number of Non-Election Shares (with the Exchange Agent to determine whether fractions of Non-Election Shares shall be rounded up or down), with the remaining number of such Holder’s Non-Election Shares being converted into the right to receive the Stock Consideration; or

(B) If the Shortfall Number exceeds the number of Non-Election Shares, then all Non-Election Shares shall be converted into the right to receive the Cash Consideration, and Stock Election Shares of each Holder thereof shall be converted into the right to receive the Cash Consideration in respect of that number of Stock Election Shares equal to the product obtained by multiplying (x) the number of Stock Election Shares held by such Holder by (y) a fraction, the numerator of which is the amount by which the Shortfall Number exceeds the total number of Non-Election Shares, and the denominator of which is the total number of Stock Election Shares (with the Exchange Agent to determine whether fractions of Stock Election Shares shall be rounded up or down), with the remaining number of such Holder’s Stock Election Shares being converted into the right to receive the Stock Consideration.

Mid Penn shall pay expenses in advance of the final disposition of any such action or proceeding to each Indemnified Party to the fullest extent as would have been permitted by 1st Colonial under the PBCL and under 1st Colonial’s articles of incorporation and bylaws, upon receipt of an undertaking to repay such advance payments if such Indemnified Party shall be adjudicated or determined to be not entitled to indemnification. Any Indemnified Party wishing to claim indemnification under this subsection upon learning of any Claim, shall notify Mid Penn (but the failure so to notify Mid Penn shall not relieve it from any liability that it may have under this subsection, except to the extent such failure materially prejudices Mid Penn) and shall deliver to Mid Penn the undertaking referred to in the previous sentence.

(c) Mid Penn shall maintain, or shall cause Mid Penn Bank to maintain, in effect for six (6) years following the Effective Time, the current directors’ and officers’ liability insurance policies covering the officers and directors of 1st Colonial (provided, that Mid Penn may substitute therefor policies of at least the same coverage containing terms and conditions which are not materially less favorable) with respect to matters occurring at or prior to the Effective Time (including the approval of this Agreement and the transactions contemplated hereby); provided, however, that in no event shall Mid Penn be required to expend pursuant to this subsection more than two hundred percent (200%) of the annual cost currently expended by 1st Colonial with respect to such insurance (the “ Maximum Amount ”); provided, further, that if the amount of the annual premium necessary to maintain or procure such insurance coverage exceeds the Maximum Amount, Mid Penn shall maintain the most advantageous policies of directors’ and officers’ insurance obtainable for a premium equal to the Maximum Amount. In lieu of the foregoing, Mid Penn or 1st Colonial, in consultation with, but only upon the consent of Mid Penn, may (and at the request of Mid Penn, 1st Colonial shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six (6)-year “tail” policy under 1st Colonial’s existing directors’ and officers’ insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent that the same may be obtained for an amount that does not exceed the Maximum Amount.

Board of Directors 1st Colonial Bancorp, Inc. 1000 Atrium Way, Suite 200 Mount Laurel, NJ, 08054

Dear Members of the Board:

We have acted as your financial advisor in connection with the proposed merger (the “Transaction”) of 1st Colonial Bancorp, Inc. (the “Company”) with and into Mid Penn Bancorp, Inc. (the “Buyer”). You have requested that we provide our opinion (the “Opinion”) as investment bankers as to whether the consideration to be received by the common stockholders of the Company (solely in their capacity as such, the “Shareholders”) in the Transaction is fair to them from a financial point of view.

Pursuant to the Agreement and Plan of Merger (the “Agreement”) to be entered into by and between the Company and the Buyer, and subject to the terms, conditions and limitations set forth therein, we understand that, subject to potential adjustments as described in the Agreement, the total consideration payable by the Buyer in the Transaction has an aggregate value of approximately $101.1 million. Such consideration, subject to potential adjustments, will consist of (i) the obligation to pay approximately $2.3 million in cash in respect of the cancellation of outstanding options on the Company’s common stock, and (ii) with respect to each outstanding share of the Company’s common stock (including restricted shares), the right to receive, at the election of the holder thereof, either $18.50 in cash or 0.6945 shares of the Buyer’s common stock, with such elections subject to proration such that, in the aggregate, 40% of the Company’s outstanding common shares will be converted into cash consideration and 60% into stock consideration. The terms and conditions of the Transaction are more fully set forth in the Agreement.

In connection with developing our Opinion we have:

(i)

reviewed certain publicly available financial statements and reports regarding the Company and the Buyer;

(ii)

reviewed certain audited financial statements regarding the Company and the Buyer;

(iii)

reviewed certain internal financial statements, management reports and other financial and operating data concerning the Company and the Buyer prepared by management of the Company and management of the Buyer, respectively;

(iv)

reviewed, on a pro forma basis, in reliance upon financial projections and other information and assumptions concerning the Company and the Buyer provided by management of the Company and management of the Buyer, as applicable, and upon consensus research estimates concerning the Buyer, the effect of the Transaction on the balance sheet, capitalization ratios, earnings and tangible book value both in the aggregate and, where applicable, on a per share basis of the Buyer;

(v)

reviewed the reported prices and trading activity for the common stock of the Company and the Buyer;

(vi)

compared the financial performance of the Company and the Buyer with that of certain other publicly-traded companies and their securities that we deemed relevant to our analysis of the Transaction;

B-1

TABLE OF CONTENTS

(vii)

reviewed the financial terms, to the extent publicly available, of certain merger or acquisition transactions that we deemed relevant to our analysis of the Transaction;

(viii)

reviewed the most recent draft of the Agreement and related documents provided to us by the Company;

(ix)

discussed with management of the Company and management of the Buyer the operations of and future business prospects for the Company and the Buyer, respectively and the anticipated financial consequences of the Transaction to the Company and the Buyer, respectively;

(x)

assisted in your deliberations regarding the material terms of the Transaction and your negotiations with the Buyer; and

(xi)

performed such other analyses and provided such other services as we have deemed appropriate.

We have relied on the accuracy and completeness of the information, financial data and financial forecasts provided to us by the Company and the Buyer and of the other information reviewed by us in connection with the preparation of our Opinion, and our Opinion is based upon such information. We have not independently verified or undertaken any responsibility to independently verify the accuracy or completeness of any of such information, data or forecasts. Management of the Company has assured us that it is not aware of any relevant information that has been omitted or remains undisclosed to us. We have not assumed any responsibility for making or undertaking an independent evaluation or appraisal of any of the assets or liabilities of the Company or of the Buyer, and we have not been furnished with any such evaluations or appraisals; nor have we evaluated the solvency or fair value of the Company or of the Buyer under any laws relating to bankruptcy, insolvency or similar matters. We have not assumed any obligation to conduct any physical inspection of the properties, facilities, assets or liabilities (contingent or otherwise) of the Company or the Buyer. We have not received or reviewed any individual loan or credit files nor have we made an independent evaluation of the adequacy of the allowance for credit losses of the Company or the Buyer. We have not made an independent analysis of the effects of potential future changes in the rate of inflation or of prevailing rates of interest or other market developments or disruptions, or of the effects of any global conflicts or hostilities or any other disaster or adversity, on the business or prospects of the Company or the Buyer. With respect to the financial projections or forecasts prepared by management of the Company and management of the Buyer, including the forecasts of potential cost savings and potential synergies, we have also assumed that such financial projections or forecasts have been reasonably prepared and reflect the best currently available estimates and judgments of management of the Company and management of the Buyer, respectively, as to the future financial performance of the Company and the Buyer, respectively, and provide a reasonable basis for our analysis. We recognize that such financial projections or forecasts are based on numerous variables, assumptions and judgments that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions) and that actual results could vary significantly from such projections or forecasts, and we express no opinion as to the reliability of such financial projections, forecasts or estimates or the assumptions upon which they are based.

As part of our investment banking business, we regularly issue fairness opinions and are continually engaged in the valuation of companies and their securities in connection with business reorganizations, private placements, negotiated underwritings, mergers and acquisitions and valuations for estate, corporate and other purposes. We are familiar with the Company and the Buyer. We issue periodic research reports regarding the business and prospects of the Buyer, and we make a market in the stock of the Buyer. We have provided investment banking services to the Buyer in recent years, including serving as financial advisor in connection with the Buyer’s acquisitions of Brunswick Bancorp and William Penn Bancorporation, which closed on May 19, 2023 and April 30, 2025, respectively, and as an underwriter on a follow-on offering of the Buyer’s common stock which priced on November 1, 2024. We are also serving as financial advisor to the Buyer in connection with another potential acquisition, and we expect to receive customary compensation for such services. We serve as financial adviser to the Company in connection with the Transaction, and we are entitled to receive from the Company reimbursement of our expenses and a fee for our services as financial adviser to the Company, a significant portion of which is contingent upon the consummation of the Transaction. We are also entitled to receive a fee from the Company for providing our

In the ordinary course of business, Stephens Inc. and its affiliates and employees at any time may hold long or short positions, and may trade or otherwise effect transactions as principal or for the accounts of customers, in debt, equity or derivative securities of any participants in the Transaction.

We are not legal, accounting, regulatory, or tax experts, and we have relied solely, and without independent verification, on the assessments of the Company and its other advisors with respect to such matters. We have assumed, with your consent, that the Transaction will not result in any materially adverse legal, regulatory, accounting or tax consequences for the Company or its shareholders and that any reviews of legal, accounting, regulatory or tax issues conducted as a result of the Transaction will be resolved favorably to the Company and its shareholders.

We further express no opinion as to the prices at which shares of the Buyer’s or Company’s common stock may trade at any time subsequent to the announcement of the Transaction.

(vi)

(vii)

the Transaction will be consummated in a manner that complies with applicable law and regulations.

This Opinion is directed to, and is for the use and benefit of, the Board of Directors of the Company (in its capacity as such) solely for purposes of assisting with its review and deliberations regarding the Transaction.

Very truly yours,

TABLE OF CONTENTS

(ii) Shares of any preferred or special class or series unless the articles, the plan or the terms of the transaction entitle all shareholders of the class or series to vote thereon and require for the adoption of the plan or the effectuation of the transaction the affirmative vote of a majority of the votes cast by all shareholders of the class or series.

“Corporation.” The issuer of the shares held or owned by the dissenter before the corporate action or the successor by merger, consolidation, division, conversion or otherwise of that issuer. A plan of division may designate which one or more of the resulting corporations is the successor corporation for the purposes

C-2

TABLE OF CONTENTS

of this subchapter. The designated successor corporation or corporations in a division shall have sole responsibility for payments to dissenters and other liabilities under this subchapter except as otherwise provided in the plan of division.

“Dissenter.” A shareholder who is entitled to and does assert dissenters rights under this subchapter and who has performed every act required up to the time involved for the assertion of those rights.

“Fair value.” The fair value of shares immediately before the effectuation of the corporate action to which the dissenter objects, taking into account all relevant factors, but excluding any appreciation or depreciation in anticipation of the corporate action.

“Interest.” Interest from the effective date of the corporate action until the date of payment at such rate as is fair and equitable under all the circumstances, taking into account all relevant factors, including the average rate currently paid by the corporation on its principal bank loans.

“Shareholder.” A shareholder as defined in section 1103 (relating to definitions) or an ultimate beneficial owner of shares, including, without limitation, a holder of depository receipts, where the beneficial interest owned includes an interest in the assets of the corporation upon dissolution.

§1573. Record and beneficial holders and owners

(a) Record holders of shares. — A record holder of shares of a business corporation may assert dissenters rights as to fewer than all of the shares registered in his name only if he dissents with respect to all the shares of the same class or series beneficially owned by any one person and discloses the name and address of the person or persons on whose behalf he dissents. In that event, his rights shall be determined as if the shares as to which he has dissented and his other shares were registered in the names of different shareholders.

(b) Beneficial owners of shares. — A beneficial owner of shares of a business corporation who is not the record holder may assert dissenters rights with respect to shares held on his behalf and shall be treated as a dissenting shareholder under the terms of this subchapter if he submits to the corporation not later than the time of the assertion of dissenters rights a written consent of the record holder. A beneficial owner may not dissent with respect to some but less than all shares of the same class or series owned by the owner, whether or not the shares so owned by him are registered in his name.

§1574. Notice of intention to dissent

If the proposed corporate action is submitted to a vote at a meeting of shareholders of a business corporation, any person who wishes to dissent and obtain payment of the fair value of his shares must file with the corporation, prior to the vote, a written notice of intention to demand that he be paid the fair value for his shares if the proposed action is effectuated, must effect no change in the beneficial ownership of his shares from the date of such filing continuously through the effective date of the proposed action and must refrain from voting his shares in approval of such action. A dissenter who fails in any respect shall not acquire any right to payment of the fair value of his shares under this subchapter. Neither a proxy nor a vote against the proposed corporate action shall constitute the written notice required by this section.

§1575. Notice to demand payment

(a) General rule. — If the proposed corporate action is approved by the required vote at a meeting of shareholders of a business corporation, the corporation shall deliver a further notice to all dissenters who gave due notice of intention to demand payment of the fair value of their shares and who refrained from voting in favor of the proposed action. If the proposed corporate action is approved by the shareholders by less than unanimous consent without a meeting or is taken without the need for approval by the shareholders, the corporation shall deliver to all shareholders who are entitled to dissent and demand payment of the fair value of their shares a notice of the adoption of the plan or other corporate action. In either case, the notice shall:

(1) State where and when a demand for payment must be sent and certificates for certificated shares must be deposited in order to obtain payment.

C-3

TABLE OF CONTENTS

(2) Inform holders of uncertificated shares to what extent transfer of shares will be restricted from the time that demand for payment is received.

(3) Supply a form for demanding payment that includes a request for certification of the date on which the shareholder, or the person on whose behalf the shareholder dissents, acquired beneficial ownership of the shares.

(4) Be accompanied by a copy of this subchapter.

(b) Time for receipt of demand for payment. — The time set for receipt of the demand and deposit of certificated shares shall be not less than 30 days from the delivery of the notice.

§1576. Failure to comply with notice to demand payment, etc.

(a) Effect of failure of shareholder to act. — A shareholder who fails to timely demand payment, or fails (in the case of certificated shares) to timely deposit certificates, as required by a notice pursuant to section 1575 (relating to notice to demand payment) shall not have any right under this subchapter to receive payment of the fair value of his shares.

(b) Restriction on uncertificated shares. — If the shares are not represented by certificates, the business corporation may restrict their transfer from the time of receipt of demand for payment until effectuation of the proposed corporate action or the release of restrictions under the terms of section 1577(a) (relating to failure to effectuate corporate action).

(c) Rights retained by shareholder. — The dissenter shall retain all other rights of a shareholder until those rights are modified by effectuation of the proposed corporate action.

§1577. Release of restrictions or payment for shares

(a) Failure to effectuate corporate action. — Within 60 days after the date set for demanding payment and depositing certificates, if the business corporation has not effectuated the proposed corporate action, it shall return any certificates that have been deposited and release uncertificated shares from any transfer restrictions imposed by reason of the demand for payment.

(b) Renewal of notice to demand payment. — When uncertificated shares have been released from transfer restrictions and deposited certificates have been returned, the corporation may at any later time send a new notice conforming to the requirements of section 1575 (relating to notice to demand payment), with like effect.

(c) Payment of fair value of shares. — Promptly after effectuation of the proposed corporate action, or upon timely receipt of demand for payment if the corporate action has already been effectuated, the corporation shall either remit to dissenters who have made demand and (if their shares are certificated) have deposited their certificates the amount that the corporation estimates to be the fair value of the shares, or give written notice that no remittance under this section will be made. The remittance or notice shall be accompanied by:

(1) The closing balance sheet and statement of income of the issuer of the shares held or owned by the dissenter for a fiscal year ending not more than 16 months before the date of remittance or notice together with the latest available interim financial statements.

(2) A statement of the corporation’s estimate of the fair value of the shares.

(3) A notice of the right of the dissenter to demand payment or supplemental payment, as the case may be, accompanied by a copy of this subchapter.

(d) Failure to make payment. — If the corporation does not remit the amount of its estimate of the fair value of the shares as provided by subsection (c), it shall return any certificates that have been deposited and release uncertificated shares from any transfer restrictions imposed by reason of the demand for payment. The corporation may make a notation on any such certificate or on the records of the corporation relating to any such uncertificated shares that such demand has been made. If shares with respect to which notation has been so made shall be transferred, each new certificate issued therefor or the records relating to

C-4

TABLE OF CONTENTS

any transferred uncertificated shares shall bear a similar notation, together with the name of the original dissenting holder or owner of such shares. A transferee of such shares shall not acquire by such transfer any rights in the corporation other than those that the original dissenter had after making demand for payment of their fair value.

§1578. Estimate by dissenter of fair value of shares

(a) General rule. — If the business corporation gives notice of its estimate of the fair value of the shares, without remitting such amount, or remits payment of its estimate of the fair value of a dissenter’s shares as permitted by section 1577(c) (relating to payment of fair value of shares) and the dissenter believes that the amount stated or remitted is less than the fair value of his shares, he may send to the corporation his own estimate of the fair value of the shares, which shall be deemed a demand for payment of the amount or the deficiency.

(b) Effect of failure to file estimate. — Where the dissenter does not file his own estimate under subsection (a) within 30 days after the mailing by the corporation of its remittance or notice, the dissenter shall be entitled to no more than the amount stated in the notice or remitted to him by the corporation.

§1579. Valuation proceedings generally

(a) General rule. — Within sixty (60) days after the latest of:

(1) effectuation of the proposed corporate action;

(2) timely receipt of any demands for payment under section 1575 (relating to notice to demand payment); or

(3) timely receipt of any estimates pursuant to section 1578 (relating to estimate by dissenter of fair value of shares);

if any demands for payment remain unsettled, the business corporation may file in court an application for relief requesting that the fair value of the shares be determined by the court.

(b) Mandatory joinder of dissenters. — All dissenters, wherever residing, whose demands have not been settled shall be made parties to the proceeding as in an action against their shares. A copy of the application shall be served on each such dissenter. If a dissenter is a nonresident, the copy may be served on him in the manner provided or prescribed by or pursuant to 42 C.S.A. Ch. 53 (relating to bases of jurisdiction and interstate and international procedure).

(c) Jurisdiction of the court. — The jurisdiction of the court shall be plenary and exclusive. The court may appoint an appraiser to receive evidence and recommend a decision on the issue of fair value. The appraiser shall have such power and authority as may be specified in the order of appointment or in any amendment thereof.

(d) Measure of recovery. — Each dissenter who is made a party shall be entitled to recover the amount by which the fair value of his shares is found to exceed the amount, if any, previously remitted, plus interest.

(e) Effect of corporation’s failure to file application. — If the corporation fails to file an application as provided in subsection (a), any dissenter who made a demand and who has not already settled his claim against the corporation may do so in the name of the corporation at any time within 30 days after the expiration of the sixty (60)-day period. If a dissenter does not file an application within the 30-day period, each dissenter entitled to file an application shall be paid the corporation’s estimate of the fair value of the shares and no more, and may bring an action to recover any amount not previously remitted.

§1580. Costs and expenses of valuation proceedings

(a) General rule. — The costs and expenses of any proceeding under section 1579 (relating to valuation proceedings generally), including the reasonable compensation and expenses of the appraiser appointed by the court, shall be determined by the court and assessed against the business corporation except that any part of the costs and expenses may be apportioned and assessed as the court deems appropriate

C-5

TABLE OF CONTENTS

against all or some of the dissenters who are parties 1578 (relating to estimate by dissenter of fair value of shares) the court finds to be dilatory, obdurate, arbitrary, vexatious or in bad faith.

(b) Assessment of counsel fees and expert fees where lack of good faith appears. — Fees and expenses of counsel and of experts for the respective parties may be assessed as the court deems appropriate against the corporation and in favor of any or all dissenters if the corporation failed to comply substantially with the requirements of this subchapter and may be assessed against either the corporation or a dissenter, in favor of any other party, if the court finds that the Party against whom the fees and expenses are assessed acted in bad faith or in a dilatory, obdurate, arbitrary or vexatious manner in respect to the rights provided by this subchapter.

(c) Award of fees for benefits to other dissenters. — If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated and should not be assessed against the corporation, it may award to those counsel reasonable fees to be paid out of the amounts awarded to the dissenters who were benefited.

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

Section 1741 of the Pennsylvania Business Corporation Law, or the PBCL, provides, in general, that a corporation will have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation), by reason of the fact that the person is or was a representative of the corporation, or is or was serving at the request of the corporation as a representative of another enterprise. Such indemnity may be against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with the action or proceeding, if the person acted in good faith and in a manner the person reasonably believed to be in, or not opposed to, the best interests of the corporation and if, with respect to any criminal proceeding, the person did not have reasonable cause to believe his conduct was unlawful.

Section 1742 of the PBCL provides, in general, that a corporation will have the power to indemnify any person who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a representative of the corporation or is or was serving at the request of the corporation as a representative of another entity. Such indemnity may be against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of the action if the person acted in good faith and in a manner the person reasonably believed to be in, or not opposed to, the best interests of the corporation, except no indemnification will be made in respect of any claim, issue, or matter as to which the person has been adjudged to be liable to the corporation unless and only to the extent that the court of common pleas of the judicial district embracing the county in which the registered office of the corporation is located or the court in which the action was brought determines upon application that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for the expenses that the court of common pleas or other court deems proper.

Under Section 1743 of the PBCL, the corporation is required to indemnify directors and officers against expenses they may incur in defending actions against them in such capacities if they are successful on the merits or otherwise in the defense of such actions. Under Section 1745 of the PBCL, a corporation may pay the expenses of a director or officer incurred in defending an action or proceeding in advance of the final disposition thereof upon receipt of an undertaking from such person to repay the amounts advanced if it is ultimately determined that such person is not entitled to indemnification from the corporation. Mid Penn’s bylaws provide indemnification of directors, officers and other agents of Mid Penn and advancement of expenses to the extent otherwise permitted by Sections 1741, 1742 and 1745 of the PBCL.

Mid Penn’s bylaws provide that the rights to indemnification and advancement of expenses in the bylaws are not exclusive, and may be in addition to, any rights granted to an indemnitee under an agreement, vote of shareholders or disinterested directors, or otherwise. As authorized by Section 1747 of the PBCL and Mid Penn’s bylaws, Mid Penn maintains, on behalf of its directors and officers, insurance protection against certain liabilities arising out of the discharge of their duties, as well as insurance covering Mid Penn for indemnification payments made to its directors and officers for certain liabilities. The premiums for such insurance are paid by Mid Penn.

The foregoing is only a general summary of certain aspects of Pennsylvania law and Mid Penn’s bylaws dealing with indemnification of directors and officers, and does not purport to be complete. The description of the bylaws is qualified in its entirety by reference to the detailed provisions of the bylaws of Mid Penn.

TABLE OF CONTENTS

the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Filing Fee Tables” or “Calculation of Registration Fee” table, as applicable, in the effective registration statement; and

(iii)

to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2)

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4)

That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: (i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; (ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(5)

That, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(6)

That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

(7)

That every prospectus (i) that is filed pursuant to paragraph (5) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

II-3

TABLE OF CONTENTS

(8)

To respond to requests for information that is incorporated by reference into this prospectus pursuant to Items 4, 10(b), 11, or 13 of this form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means; this includes information contained in documents filed subsequent to the effective date of this registration statement through the date of responding to the request.

(9)

To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.

(10)

Insofar as indemnification for liabilities under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable. In the event a claim of indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in a successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
