Mid Penn Bancorp (MPB) plans merger with 1st Colonial and bank subsidiary

Rhea-AI Filing Summary

Mid Penn Bancorp, Inc. announced that it has entered into an Agreement and Plan of Merger with 1st Colonial Bancorp, Inc.. Under this agreement, 1st Colonial will merge with and into Mid Penn, with Mid Penn as the surviving company. Shortly after that step, 1st Colonial Community Bank, a New Jersey-chartered bank and subsidiary of 1st Colonial, will merge into Mid Penn Bank, which will remain the surviving bank.

Mid Penn issued a press release and an investor presentation describing the transaction, which are included as exhibits. To complete the combination, Mid Penn plans to file a Form S-4 to register Mid Penn common stock to be issued in the deal, including a proxy statement/prospectus for 1st Colonial shareholders, who will be asked to approve the transaction. The filing emphasizes that closing remains subject to regulatory, shareholder and other approvals and highlights typical integration, regulatory, economic and industry risks through extensive forward-looking statements language.

Insights

Bank M&A and capital markets analyst

Mid Penn outlines a stock-for-stock bank merger with 1st Colonial, pending approvals and integration execution.

The disclosure centers on Mid Penn Bancorp agreeing to merge with 1st Colonial Bancorp, followed by a combination of their bank subsidiaries into Mid Penn Bank. Structurally, this is a classic bank holding company merger with a downstream bank merger, using Mid Penn common stock as consideration, as indicated by the planned Form S-4 registration and proxy statement/prospectus for 1st Colonial shareholders.

The transaction still depends on regulatory and shareholder approvals, as well as successful operational integration once completed. The extensive forward-looking statements section details risks such as potential delays, failure to realize revenue or expense synergies, integration challenges, reputational effects, and broader banking-sector pressures including interest-rate changes, deposit dynamics and credit quality. Without disclosed deal value, pricing or synergy targets in this excerpt, the financial impact cannot be assessed here, but the combination would meaningfully change Mid Penn’s franchise footprint and risk profile once closed.

This communication may contain forward-looking statements, including, but not limited to, certain plans, expectations, goals, projections, and statements about the benefits of the proposed business combination transaction between Mid Penn and 1st Colonial (the “Transaction”), the plans, objectives, expectations and intentions of Mid Penn and 1st Colonial, the expected timing of completion of the Transaction, and other statements that are not historical facts. All statements other than statements of historical fact, including statements about beliefs and expectations, are forward-looking statements. Forward-looking statements may be identified by words such as “may,” “will,” “should,” “could,” “would,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target” and similar expressions. Forward-looking statements, by their nature, are subject to risks and uncertainties. There are many factors that could cause actual results to differ materially from expected results described in the forward-looking statements. The forward-looking statements are intended to be subject to the safe harbor provided by Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995.

Factors relating to the Transaction that could cause or contribute to actual results differing materially from those contained or implied in forward-looking statements or historical performance include, in addition to those factors identified elsewhere in this communication the occurrence of any event, change or other circumstances that could give rise to the right of Mid Penn or 1st Colonial to terminate the definitive merger agreement governing the terms and

conditions of the Transaction; the outcome of any legal proceedings that may be instituted against Mid Penn or 1st Colonial; the possibility that revenue or expense synergies or the other expected benefits of the Transaction may not fully materialize or may take longer to realize than expected, or may be more costly to achieve than anticipated, including as a result of the impact of, or problems arising from, the integration of the two companies, the strength of the economy and competitive factors in the areas where Mid Penn and 1st Colonial do business, or other unexpected factors or events; the possibility that the Transaction may not be completed when expected or at all because required regulatory, shareholder or other approvals or other conditions to closing are not received or satisfied on a timely basis or at all (and the risk that such approvals may result in the imposition of conditions that could adversely affect Mid Penn or 1st Colonial or the expected benefits of the Transaction); the risk that Mid Penn is unable to successfully and promptly implement its integration strategies; reputational risks and potential adverse reactions from or changes to the relationships with the companies’ customers, employees or other business partners, including resulting from the announcement or the completion of the Transaction; the dilution caused by Mid Penn’s issuance of common stock in connection with the Transaction; diversion of management’s attention and time from ongoing business operations and other opportunities on matters relating to the Transaction; and other factors that may affect the future results of Mid Penn and 1st Colonial, including continued pressures and uncertainties within the banking industry and Mid Penn’s and 1st Colonial’s markets, including changes in interest rates and deposit amounts and composition, adverse developments in the level and direction of loan delinquencies, charge-offs, and estimates of the adequacy of the allowance for loan losses, increased competitive pressures, asset and credit quality deterioration, the impact of proposed or imposed tariffs by the U.S. government or retaliatory tariffs proposed or imposed by U.S. trading partners that could have an adverse impact on customers or any recession or slowdown in economic growth particularly in the markets in which Mid Penn or 1st Colonial operate, and legislative, regulatory, and fiscal policy changes and related compliance costs.

These factors are not necessarily all of the factors that could cause Mid Penn’s or 1st Colonial’s actual results, performance, or achievements to differ materially from those expressed in or implied by any of the forward-looking statements. Other unknown or unpredictable factors also could harm Mid Penn’s or 1st Colonial’s results.

Further information regarding Mid Penn and factors that could affect the forward-looking statements contained herein can be found in Mid Penn’s Annual Report on Form 10-K for the year ended December 31, 2024, which is accessible on the Securities and Exchange Commission’s (the “SEC”) website at www.sec.gov and under the Investors link on Mid Penn’s website at www.midpennbank.com, and in other documents Mid Penn files with the SEC.

Forward-looking statements speak only as of the date they are made and Mid Penn and 1st Colonial do not undertake or assume any obligation to update publicly any of these statements to reflect actual results, new information or future events, changes in assumptions, or changes in other factors affecting forward-looking statements, except to the extent required by applicable law. If Mid Penn or 1st Colonial update one or more forward-looking statements, no inference should be drawn that Mid Penn or 1st Colonial will make additional updates with respect to those or other forward-looking statements.
