Nothing in this form shall be construed to imply that the Commission has verified any information contained herein.

If the notification relates to a portion of the filing checked above, identify the Item(s) to which the notification relates:

PART I — REGISTRANT INFORMATION

Mid Penn Bancorp, Inc.

(Full Name of Registrant)

(Former Name if Applicable)

2407 Park Drive

(Address of Principal Executive Office (Street and Number))

Harrisburg, PA 17110

(City, State and Zip Code)

PART II — RULES 12b-25(b) AND (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

☒	(a)	The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense;
	(b)	The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-CEN or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and
	(c)	The accountant’s statement or other exhibit required by Rule 12b-25(c) has been attached if applicable.

PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period. (Attach Extra Sheets if Needed)

Mid Penn Bancorp, Inc. (the “Registrant”) is not able to file its annual report on Form 10-K (the “Form 10-K”) within the prescribed time period as the Registrant is still providing information and documentation to its auditors, RSM US, LLP (“RSM”) in connection with its audit procedures relating to the Registrant’s acquisition of Brunswick Bancorp during the year ended December 31, 2023. The Registrant does not believe these matters could have been completed by the prescribed filing date without unreasonable effort or expense. The Registrant is evaluating if a material weakness in the effectiveness of the Registrant’s internal controls over financial reporting related to its purchase accounting of the Brunswick Bancorp acquisition exists. This delay is not the result of any disagreements with RSM on any accounting matters, financial statement disclosures or auditing procedure.

Although the Form 10-K is not complete, the Registrant expects that the financial statements in the Form 10-K will be materially consistent with the financial information furnished in the earnings release attached as Exhibit 99.1 to the Registrant’s Current Report on Form 8-K dated January 24, 2024 (the “Earnings Release”). The Registrant further expects that the results of its evaluation, which is still ongoing, will not have a material impact on the financial statements contained in its Quarterly Reports on Form 10-Q for the quarters ended March, 31, 2023, June 30, 2023 or September 30, 2023.

The Registrant expects to file its Form 10-K no later than fifteen calendar days following the due date of the Form 10-K.

If answer is no, identify report(s). ☒ Yes ☐ No
(3)		Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? ☐ Yes ☒ No*
		If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.
		*   The Registrant does not expect any changes to the financial results it previously furnished in the Earnings Release.
