NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 - Summary of Significant Accounting Policies

Basis of Presentation

For all periods presented, the accompanying consolidated financial statements include the accounts of Mid Penn Bancorp, Inc., its wholly-owned subsidiary, Mid Penn Bank, and four nonbank subsidiaries, MPB Financial Services, LLC, which includes MPB Wealth Management, LLC and MPB Risk Services, LLC, and MPB Launchpad Fund I, LLC. As of September 30, 2023, the accounts and activities of these nonbank subsidiaries were not material to warrant separate disclosure or segment reporting. As a result, Mid Penn has only one reportable segment for financial reporting purposes. All material intercompany accounts and transactions have been eliminated in consolidation.

Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC. Mid Penn believes the information presented is not misleading, and the disclosures are adequate. For comparative purposes, the September 30, 2022 and December 31, 2022 balances have been reclassified, when necessary, to conform to the 2023 presentation. Such reclassifications had no impact on net income or total shareholders’ equity. In the opinion of management, all adjustments necessary for fair presentation of the periods presented have been reflected in the accompanying consolidated financial statements. All such adjustments are of a normal, recurring nature. These unaudited interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the 2022 Annual Report.

Mid Penn has evaluated events and transactions occurring subsequent to the balance sheet date of September 30, 2023, for items that should potentially be recognized or disclosed in these consolidated financial statements. The evaluation was conducted through the issuance date of these consolidated financial statements.

CECL Adoption and Updated Significant Accounting Policy

On January 1, 2023, the Corporation adopted ASU 2016-13, Financial Instruments - Credit Losses (ASC Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss methodology, and is referred to as CECL. The measurement of expected credit losses under CECL is applicable to financial assets measured at amortized cost, including loans and HTM debt securities. It also applies to OBS credit exposures (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in leases recognized by a lessor in accordance with ASC Topic 842.

The Corporation adopted CECL using the modified retrospective method for all financial assets measured at amortized cost, net of investments in leases and OBS credit exposures. Results for reporting periods beginning after January 1, 2023 are presented under CECL, while prior period results are reported in accordance with the previously applicable incurred loss methodology. The Corporation recorded an overall increase of $15.0 million to the ACL on January 1, 2023 as a result of the adoption of CECL. Retained earnings decreased $11.5 million and deferred tax assets increased by $3.1 million. Included in the $15.0 million increase to the ACL was $3.1 million for certain OBS credit exposures that were previously recognized in other liabilities before the adoption of CECL.

On January 1, 2023, the Corporation adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, which eliminates the accounting guidance for troubled debt restructurings in Accounting Standards Codification ("ASC") Subtopic 310-40, Receivables - Troubled Debt Restructurings by Creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, ASU 2022-02 requires entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of ASC Subtopic 326-20, Financial Instruments - Credit Losses - Measured at Amortized Cost. See "Note 4 - Loans and Allowance for Credit Losses - Loans" for the new financial statement disclosures applicable under this update.

The updates to the significant accounting policies related to CECL are further discussed in "Note 3 - Investment Securities", "Note 4 - Loans and Allowance for Credit Losses - Loans" and "Note 8 - Commitments and Contingencies".

All other significant accounting policies used in preparation of the Consolidated Financial Statements are disclosed in the 2022 Annual Report. Those significant accounting policies are unchanged at September 30, 2023.

Accounting Standards Pending Adoption

ASU No. 2023-02: The FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.

The amendments in this update permit reporting entities to elect to account for their tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain conditions are met. A reporting entity may make an accounting policy election to apply the proportional amortization method on a tax-credit-program-by-tax-credit-program basis rather than electing to apply the proportional amortization method at the reporting entity level or to individual investments. The amendments in this update also remove certain guidance for Qualified Affordable Housing Project investments and require the application of the delayed equity contribution guidance to all tax equity investments. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and must be applied on either a modified retrospective or a retrospective basis. Early adoption is permitted in any interim period, however if adopted in an interim period the entity shall adopt the amendments in this update as of the beginning of the fiscal year that includes the interim period. The Corporation does not expect the adoption of ASU No. 2023-02 to have a material impact on its consolidated financial statements.

ASU 2023-06: The FASB issued ASU 2023-06, Disclosure Improvements - Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative.

ASU 2023-06 amends the ASC to incorporate certain disclosure requirements from SEC Release No. 33-10532 - Disclosure Update and Simplification that was issued in 2018. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. ASU 2023-06 is not expected to have a significant impact on our financial statements.

Note 2 - Business Combination

Brunswick Acquisition

On May 19, 2023, Mid Penn completed its acquisition of Brunswick through the merger of Brunswick with and into Mid Penn with Mid Penn being the surviving corporation. In connection with this acquisition, Brunswick Bank, a wholly-owned subsidiary of Brunswick, merged with and into Mid Penn Bank, a wholly-owned subsidiary of Mid Penn.

This transaction included the acquisition of 5 branches and extended Mid Penn’s footprint into Middlesex and Monmouth counties in central New Jersey. Mid Penn issued 849,510 shares of its common stock as well as a net cash payment to Brunswick shareholders of $27.6 million, for total consideration of $45.7 million for all outstanding stock and the cancellation of stock options of Brunswick.

Mid Penn has recognized total goodwill of $15.5 million, which is calculated as the excess of both the consideration exchanged and liabilities assumed compared to the fair market value of identifiable assets acquired. The fair value of the consideration exchanged related to Mid Penn’s common stock was calculated based upon the closing market price of Mid Penn’s common stock as of May 19, 2023. None of the goodwill recognized is expected to be deductible for income tax purposes.

Mid Penn incurred expenses related to the Brunswick Acquisition of $352 thousand for the three months ended September 30, 2023 and $8.5 million for the nine months ended September 30, 2023, which are included in noninterest expense in the Consolidated Statements of Income.

Purchased loans and leases that reflect a more-than-insignificant deterioration of credit from origination are considered PCD. Mid Penn considers various factors in connection with the identification of more-than-insignificant deterioration in credit, including but not limited to nonperforming status, delinquency, risk ratings, FICO scores and other qualitative factors that indicate deterioration in credit quality since origination. For PCD loans and leases, the initial estimate of expected credit losses is recognized in the ACL on the date of acquisition using the same methodology as other loans and leases held-for-investment. As part of the Brunswick Acquisition, Mid Penn acquired PCD loans and leases of $18.7 million. Mid Penn established an ACL at acquisition of $355 thousand with a corresponding gross-up to the amortized cost of the PCD loans and leases. The non-credit discount on the PCD loans and leases was $2.1 million and the

Day 1 fair value was $16.6 million. The initial provision expense for non-PCD loans associated with the Brunswick Acquisition was $2.0 million.

Estimated fair values of the assets acquired and liabilities assumed in the Brunswick Acquisition as of the closing date are as follows:

(In thousands)
Assets acquired:
Cash and cash equivalents			$	21,029
Federal funds sold			7,604
Investment securities			1,825
Loans			324,471
Goodwill			15,521
Core deposit intangible			999
Premises and equipment			5,315
Cash surrender value of life insurance			3,361
Deferred income taxes			6,792
Accrued interest receivable			1,171
Other assets			3,860
Total assets acquired			391,948
Liabilities assumed:
Deposits:
Noninterest-bearing demand			62,123
Interest-bearing demand			11,767
Money Market			47,362
Savings			14,203
Time			147,164
Long-term debt			60,137
Accrued interest payable			1,911
Other liabilities			1,621
Total liabilities assumed			346,288
Consideration paid			$	45,660
Cash paid			$	27,565
Fair value of common stock issued			18,095

Management has completed its evaluation of fair values of all assets and liabilities shown in the table above and all amounts are considered final. Measurement period adjustments for the three months ending September 30, 2023 were $349 thousand related to securities paydowns received after the acquisition date that relate to the period before the acquisition date, as well as a $6.4 million reclass between noninterest-bearing demand and interest-bearings demand deposits.

Note 3 - Investment Securities

FASB ASU 2016-13, "Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments," was adopted by Mid Penn on January 1, 2023. ASU 2016-13 introduces the CECL methodology for estimating allowances for credit losses. ASU 2016-13 applies to all financial instruments carried at amortized cost, including HTM securities, and makes targeted improvements to the accounting for credit losses on AFS securities.

In order to comply with ASC 326, Mid Penn conducted a review of its investment portfolio and determined that for certain classes of securities it would be appropriate to assume the expected credit loss to be zero. This zero-credit loss assumption applies to debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. The reasons behind the adoption of the zero-credit loss assumption are as follows:

•High credit rating

•Long history with no credit losses

•Guaranteed by a sovereign entity

•Widely recognized as "risk-free rate"

•Can print its own currency

•Currency is routinely held by central banks, used in international commerce, and commonly viewed as reserve currency

•Currently under the U.S. Government conservatorship or receivership

Mid Penn will continuously monitor any changes in economic conditions, credit downgrades, changes to explicit or implicit guarantees granted to certain debt issuers, and any other relevant information that would indicate potential credit deterioration and prompt Mid Penn to reconsider its zero-credit loss assumption.

At the date of adoption, Mid Penn’s estimated allowance for credit losses on AFS and HTM securities under ASU 2016-13 was deemed immaterial due to the composition of these portfolios. Both portfolios consist primarily of U.S. government agency guaranteed mortgage-backed securities for which the risk of loss is minimal. Therefore, Mid Penn did not recognize a cumulative effect adjustment through retained earnings related to the AFS and HTM securities.

AFS Securities

ASU 2016-13 makes targeted improvements to the accounting for credit losses on AFS securities. The concept of other-than-temporarily impaired has been replaced with the allowance for credit losses. Unlike HTM securities, AFS securities are evaluated on an individual level and pooling of securities is not allowed.

Quarterly, Mid Penn evaluates if any security has a fair value less than its amortized cost. Once these securities are identified, in order to determine whether a decline in fair value resulted from a credit loss or other factors, Mid Penn performs further analysis as outlined below:

•Review the extent to which the fair value is less than the amortized cost and observe the security’s lowest credit rating as reported by third-party credit ratings companies.

•The securities that violate the credit loss triggers above would be subjected to additional analysis that may include, but is not limited to: changes in market interest rates, changes in securities credit ratings, security type, service

area economic factors, financial performance of the issuer/or obligor of the underlying issue and third-party guarantee.

•If Mid Penn determines that a credit loss exists, the credit portion of the allowance will be measured using a DCF analysis using the effective interest rate as of the security’s purchase date. The amount of credit loss Mid Penn records will be limited to the amount by which the amortized cost exceeds the fair value.

The DCF analysis utilizes contractual maturities, as well as third-party credit ratings and cumulative default rates published annually by a reputable third-party.

At September 30, 2023, the results of the analysis did not identify any securities that violate the credit loss triggers; therefore, no DCF analysis was performed and no credit loss was recognized on any of the securities available for sale.

Accrued interest receivable is excluded from the estimate of credit losses for AFS securities. At September 30, 2023, accrued interest receivable totaled $1.0 million for AFS securities and was reported in accrued interest receivable on the accompanying Consolidated Balance Sheet.

HTM Securities

ASU 2016-13 requires institutions to measure expected credit losses on financial assets carried at amortized cost on a collective or pool basis when similar risks exist. Mid Penn uses several levels of segmentation in order to measure expected credit losses:

•The portfolio is segmented into agency and non-agency securities.

•The non-agency securities are separated into state and political subdivision obligations and corporate debt securities.

Each individual segment is categorized by third-party credit ratings.

As discussed above, Mid Penn has determined that for certain classes of securities it would be appropriate to assume the expected credit loss to be zero, which include debt issuances of the U.S. Treasury and agencies and instrumentalities of the United States government. This assumption will be reviewed and attested to quarterly.

At September 30, 2023, Mid Penn’s HTM securities totaled $401.6 million. After applying appropriate probability of default and loss given default assumptions, the total amount of current expected credit losses was deemed immaterial. Therefore, no reserve was recorded at September 30, 2023.

Accrued interest receivable is excluded from the estimate of credit losses for HTM securities. At September 30, 2023, accrued interest receivable totaled $2.4 million for HTM securities and was reported in accrued interest receivable on the accompanying Consolidated Balance Sheet.

At September 30, 2023, Mid Penn had no HTM securities that were past due 30 days or more as to principal or interest payments. Mid Penn had no HTM securities classified as nonaccrual at September 30, 2023.

Note 4 - Loans and Allowance for Credit Losses - Loans

Mid Penn adopted the amendments of FASB ASU 2016-13, on January 1, 2023. The amendments of ASU 2016-13 created FASB ASC Topic 326, "Financial Instruments – Credit Losses," which, among other things, replace much of the guidance and disclosures previously provided in FASB ASC Topic 310, "Receivables." The guidance in FASB ASC Topic 326 replaces the incurred loss methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to determine credit losses. In accordance with FASB ASC Subtopic 326-20, "Financial Instruments – Credit Losses – Measured at Amortized Cost," Mid Penn has developed an ACL methodology effective January 1, 2023, which replaces its previous allowance for loan losses methodology. See the section captioned "Allowance for Credit Losses, effective January 1, 2023" within this note for additional information regarding Mid Penn’s ACL. Mid Penn adopted FASB ASC Topic 326 using the modified retrospective approach prescribed by the amendments of ASU 2016-13; therefore, prior period balances are presented under legacy GAAP and may not be comparable to current period presentation.

Loans, net of unearned income, are summarized as follows by portfolio segment:

(In thousands)			September 30, 2023						December 31, 2022
Commercial real estate (1)			$	2,288,396					$	2,052,934
Commercial and industrial			648,439						596,042
Construction			462,215						441,246
Residential mortgage (1)			743,533						416,221
Consumer			3,074						7,676
Total loans			$	4,145,657					$	3,514,119

(1) In accordance with the guidance in FASB ASC Topic 326, Mid Penn redefined its loan portfolio segments and related loan classes based on the level at which risk is monitored within the ACL methodology. As such, $181.9 million of loans were reclassified from Commercial real estate to Residential mortgage upon adoption of CECL on January 1, 2023. Prior periods were not reclassified.

Total loans are stated at the amount of unpaid principal, adjusted for net deferred fees and costs. Net deferred loan fees of $3.9 million reduced the carrying value of loans as of September 30, 2023 and December 31, 2022, respectively.

Accrued interest receivable is not included in the amortized cost basis of Mid Penn's loans. At September 30, 2023, accrued interest receivable for loans totaled $20.4 million with no related ACL and was reported in other assets on the accompanying Consolidated Balance Sheet.

Credit Quality Indicators

Mid Penn categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. On a minimum of a quarterly basis, Mid Penn analyzes loans individually to classify the loans as to their credit risk. The following table presents risk ratings by loan portfolio segment and origination year, which is the year of origination or renewal.

Mid Penn had no loans classified as "doubtful" as of September 30, 2023 and December 31, 2022.

Collateral-Dependent Loans

A financial asset is considered to be collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. For all classes of financial assets deemed collateral-dependent, Mid Penn elected the practical expedient to estimate expected credit losses based on the collateral’s fair value less cost to sell. In most cases, Mid Penn records a partial charge-off to reduce the loan’s carrying value to the collateral’s fair value less cost to sell. Substantially all of the collateral supporting collateral-dependent financial assets consists of various types of real estate, including residential properties; commercial properties such as retail centers, office buildings, and lodging; agriculture land; and vacant land.

Allowance for Credit Losses, effective January 1, 2023

Mid Penn’s ACL - loans methodology is based upon guidance within FASB ASC Subtopic 326-20, as well as regulatory guidance from the FDIC, its primary federal regulator. The ACL - loans is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Credit quality within the loan portfolio is continuously monitored by management and is reflected within the ACL - loans. The ACL - loans is an estimate of expected losses inherent within Mid Penn’s existing loan portfolio. The ACL - loans is adjusted through the PCL and reduced by the charge off of loan amounts, net of recoveries.

The loan loss estimation process involves procedures to appropriately consider the unique characteristics of Mid Penn’s loan portfolio segments. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the allowance is complex and requires judgement by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the ACL and credit loss expense.

Mid Penn estimates the ACL using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Mid Penn uses a third-party software application to calculate the quantitative portion of the ACL using a methodology and assumptions specific to each loan pool. The qualitative portion of the allowance is based on general economic conditions and other internal and external factors affecting Mid Penn as a whole, as well as specific loans. Factors considered include the following: lending process, concentrations of credit, and credit quality. The quantitative and qualitative portions of the allowance are added together to determine the total ACL, which reflects management’s expectations of future conditions based on reasonable and supportable forecasts.

The methodology for estimating the amount of expected credit losses reported in the ACL has two basic components: a collective, or pooled, component for estimated expected credit losses for pools of loans that share similar risk characteristics, and an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. In estimating the ACL for the collective component, loans are segregated into loan pools based on loan purpose codes and similar risk characteristics.

The commercial real estate and residential mortgage loan portfolio segments include loans for both commercial and residential properties that are secured by real estate. The underwriting process for these loans includes analysis of the financial position and strength of both the borrower and, if applicable, guarantor, experience with similar projects in the past, market demand and prospects for successful completion of the proposed project within the established budget and schedule, values of underlying collateral, availability of permanent financing, maximum loan-to-value ratios, minimum equity requirements, acceptable amortization periods and minimum debt service coverage requirements, based on property type. The borrower’s financial strength and capacity to repay their obligations remain the primary focus of underwriting. Financial strength is evaluated based upon analytical tools that consider historical and projected cash flows and performance, in addition to analysis of the proposed project for income-producing properties. Additional support offered by guarantors is also considered when applicable. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity and availability of long-term financing.

The commercial and industrial loan portfolio segment includes commercial loans made to many types of businesses for various purposes, such as short-term working capital loans that are usually secured by accounts receivable and inventory, equipment and fixed asset purchases that are secured by those assets, and term financing for those within Mid Penn’s

geographic markets. Mid Penn’s credit underwriting process for commercial and industrial loans includes analysis of historical and projected cash flows and performance, evaluation of financial strength of both borrowers and guarantors as reflected in current and detailed financial information, and evaluation of underlying collateral to support the credit.

The consumer loan portfolio segment is comprised of loans which are underwritten after evaluating a borrower’s capacity, credit and collateral. Several factors are considered when assessing a borrower’s capacity, including the borrower’s employment, income, current debt, assets and level of equity in the property. Credit is assessed using a credit report that provides credit scores and the borrower’s current and past information about their credit history. Loan-to-value and debt-to-income ratios, loan amount and lien position are also considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends, such as conditions that negatively affect housing prices and demand and levels of unemployment.

Mid Penn utilizes a DCF method to estimate the quantitative portion of the allowance for credit losses for loan pools. The DCF is based off of historical losses, including peer data, which is correlated to national unemployment and GDP.

The PD and LGD measures are used in conjunction with prepayment data as inputs into the DCF model to calculate the cash flows at the individual loan level. Contractual cash flows based on loan terms are adjusted for PD, LGD and prepayments to derive loss cash flows. These loss cash flows are discounted by the loan’s coupon rate to arrive at the discounted cash flow based quantitative loss. The prepayment studies are updated quarterly by a third-party for each applicable pool.

Mid Penn determined that reasonable and supportable forecasts could be made for a twelve-month period for all of its loan pools. To the extent the lives of the loans in the LHFI portfolio extend beyond this forecast period, Mid Penn uses a reversion period of four quarters and reverts to the historical mean on a straight-line basis over the remaining life of the loans.

Qualitative factors used in the ACL methodology include the following:

•Lending process

•Concentrations of credit

The ACL for individual loans, such as non-accrual and PCD, that do not share risk characteristics with other loans is measured as the difference between the discounted value of expected future cash flows, based on the effective interest rate at origination, and the amortized cost basis of the loan, or the net realizable value. The ACL is the difference between the loan’s net realizable value and its amortized cost basis (net of previous charge-offs and deferred loan fees and costs), except for collateral-dependent loans. A loan is collateral dependent when the borrower is experiencing financial difficulty and repayment of the loan is expected to be provided substantially through the sale of the collateral. The expected credit loss for collateral-dependent loans is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, adjusted for the estimated cost to sell. Fair value estimates for collateral-dependent loans are derived from appraised values based on the current market value or the "as is" value of the collateral, normally from recently received and reviewed appraisals. Current appraisals are ordered on a regular basis based on the inspection date or more often if market conditions necessitate. Appraisals are obtained from state-certified appraisers and are based on certain assumptions, which may include construction or development status and the highest and best use of the property. These appraisals are reviewed by Mid Penn’s Appraisal Review Department to ensure they are acceptable, and values are adjusted down for costs associated with asset disposal. If the calculated expected credit loss is determined to be permanent or not recoverable, the amount of the expected credit loss is charged off.

Mid Penn may also purchase loans or acquire loans through a business combination. At the purchase or acquisition date, loans are evaluated to determine whether there has been more than insignificant credit deterioration since origination. Loans that have experienced more than insignificant credit deterioration since origination are referred to as PCD loans. In its evaluation of whether a loan has experienced more than insignificant deterioration in credit quality since origination, Mid Penn takes into consideration loan grades, past due and nonaccrual status. Mid Penn may also consider external credit rating agency ratings for borrowers and for non-commercial loans, FICO score or band, probability of default levels, and number of times past due. At the purchase or acquisition date, the amortized cost basis of PCD loans is equal to the purchase price and an initial estimate of credit losses. The initial recognition of expected credit losses on PCD loans has no impact on net income. When the initial measurement of expected credit losses on PCD loans is calculated on a pooled loan basis, the expected credit losses are allocated to each loan within the pool. Any difference between the initial amortized cost basis and the unpaid principal balance of the loan represents a noncredit discount or premium, which is accreted (or amortized) into interest income over the life of the loan. Subsequent changes to the ACL on PCD loans are recorded through the PCL. For purchased loans that are not deemed to have experienced more than insignificant credit deterioration

since origination and are therefore not deemed PCD, any discounts or premiums included in the purchase price are accreted (or amortized) over the contractual life of the individual loan.

Loans are charged off against the ACL, with any subsequent recoveries credited back to the ACL account. Expected recoveries may not exceed the aggregate of amounts previously charged off and expected to be charged off.

Modifications to Borrowers Experiencing Financial Difficulty

From time to time, we may modify certain loans to borrowers who are experiencing financial difficulty. In some cases, these modifications may result in new loans. Loan modifications to borrowers experiencing financial difficulty may be in the form of principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, or a term extension, or a combination thereof, among other things.

There were no new modifications for the quarter ending September 30, 2023. Information related to loans modified (by type of modification), whereby the borrower was experiencing financial difficulty at the time of modification, is set forth in the following table:

(In thousands)			Interest Only						Term Extension						Combination: Interest Only and Term Extension						Total						% of Total Class of Financing Receivable
Nine months ended September 30, 2023
Commercial real estate			$	51					$	—					$	180					$	231					0.01		%
Commercial and industrial			—						150						—						150						0.02
Total			$	51					$	150					$	180					$	381					0.01		%

The financial effects of the interest-only loan modifications reduced the monthly payment amounts for the borrower and the term extensions in the table above added a weighted-average of 2.0 years to the life of the loans, which also reduced the monthly payment amounts for the borrowers.

Note 5 - Derivative Financial Instruments

Mid Penn manages its exposure to certain interest rate risks through the use of derivatives; however, none are entered into for speculative purposes. During the first nine months of 2023, Mid Penn entered into outstanding derivative contracts designated as hedges. As of December 31, 2022, Mid Penn did not designate any derivative financial instruments as formal hedging relationships. Mid Penn’s free-standing derivative financial instruments are required to be carried at their fair value on the Consolidated Balance Sheets.

Mortgage Banking Derivative Financial Instruments

In connection with its mortgage banking activities, Mid Penn enters into commitments to originate certain fixed-rate residential mortgage loans for customers, also referred to as interest rate locks. In addition, Mid Penn enters into forward commitments for the future sales or purchases of mortgage-backed securities to or from third-party counterparties to hedge the effect of changes in interest rates on the values of both the interest rate locks and mortgage loans held for sale. Forward sales commitments may also be in the form of commitments to sell individual mortgage loans at a fixed price at a future date. The amount necessary to settle each interest rate lock is based on the price that secondary market investors would pay for loans with similar characteristics, including interest rate and term, as of the date fair value is measured.

For the three months ended September 30, 2023 and 2022, Mid Penn recorded net gains from mortgage banking hedging activity of $67 thousand and $217 thousand, respectively. For the nine months ended September 30, 2023 and 2022, Mid Penn recorded net gains from mortgage banking hedging activity of $215 thousand and $1.3 million, respectively.

Loan-level Interest Rate Swaps

Mid Penn enters into loan-level interest rate swaps with certain qualifying, creditworthy commercial loan customers to meet their interest rate risk management needs. Mid Penn simultaneously enters into parallel interest rate swaps with dealer counterparties, with identical notional amounts and terms. The net result of the offsetting customer and dealer counterparty swap agreements is that the customer pays a fixed rate of interest and Mid Penn receives a floating rate. Mid Penn’s loan-level interest rate swaps are considered derivatives, but are not accounted for using hedge accounting.

Cash Flow Hedges of Interest Rate Risk

Mid Penn’s objectives in using interest rate derivatives are to reduce volatility in net interest income and to manage its exposure to interest rate movements. To accomplish this objective, Mid Penn primarily uses interest rate swaps as part of its interest rate risk management strategy. During the first nine months of 2023, Mid Penn entered into interest rate swaps designated as cash flow hedges to hedge the cash flows associated with existing brokered CDs.

There were no cash flow hedges at December 31, 2022.

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the unrealized gain or loss on the derivative is recorded in AOCI and subsequently reclassified into interest income in the same period during which the hedged transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest income as interest payments are made on Mid Penn’s variable-rate liabilities. During the next twelve months, Mid Penn estimates that an additional $2.9 million will be reclassified as a decrease to interest expense.

Note 7 - Fair Value Measurement

The Corporation uses estimates of fair value in applying various accounting standards for its consolidated financial statements on either a recurring or non-recurring basis. Fair value is defined as the price to sell an asset or transfer a liability in an orderly transaction between willing and able market participants. Mid Penn groups its assets and liabilities measured at fair value in three hierarchy levels, based on the observability and transparency of the inputs. The fair value hierarchy is as follows:

Level 1 - Inputs that represent quoted prices for identical instruments in active markets.

Level 2 - Inputs that represent quoted prices in markets that are not active, or inputs that are observable either directly or indirectly, for substantially the full term of the asset or liability.

Level 3 - Inputs that are largely unobservable, as little or no market data exists for the instrument being valued.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below.

There were no transfers of assets between fair value Level 1 and Level 2 during the three and nine months ended September 30, 2023 or the year ended December 31, 2022.

The following tables illustrate the assets measured at fair value on a recurring basis and reported on the Consolidated Balance Sheets.

Table of Contents

MID PENN BANCORP, INC.

The valuation methodologies and assumptions used to estimate the fair value for the items in the preceding tables are as follows:

Available for sale investment securities - The fair value of equity and debt securities classified as available for sale is determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1), or matrix pricing (Level 2), which is a mathematical technique used widely in the industry to value debt securities without relying exclusively on quoted market prices for the specific securities, but rather, relying on the securities’ relationship to other benchmark quoted prices.

Equity securities - The fair value of equity securities with readily determinable fair values is recorded on the Consolidated Balance Sheet, with realized and unrealized gains and losses reported in other expense on the Consolidated Statements of Income.

Loans held for sale - This category includes mortgage loans held for sale that are measured at fair value. Fair values as of September 30, 2023 were measured as the price that secondary market investors were offering for loans with similar characteristics.

Derivative assets - Interest rate swaps are measured by alternative pricing sources with reasonable levels of price transparency in markets that are not active. Based on the complex nature of interest rate swap agreements, the markets these instruments trade in are not as efficient and are less liquid than that of the more mature Level 1 markets. These markets do, however, have comparable, observable inputs in which an alternative pricing source values these assets in order to arrive at a fair market value. These characteristics classify interest rate swap agreements as Level 2.

Mortgage banking derivatives represent the fair value of mortgage banking derivatives in the form of interest rate locks and forward commitments with secondary market investors and the fair value of interest rate swaps. The fair values of Mid Penn’s interest rate locks, forward commitments and interest rate swaps represent the amounts that would be required to settle the derivative financial instruments at the balance sheet date. These characteristics classify interest rate swap agreements as Level 2. See "Note 5 - Derivative Financial Instruments," for additional information.

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. The following table illustrates Level 3 financial instruments measured at fair value on a nonrecurring basis:

(In thousands)						September 30, 2023						December 31, 2022
Individually evaluated loans, net of ACL						$	12,371					$	4,022
Foreclosed assets held for sale						905						43

Net loans - This category consists of loans that were individually evaluated for credit losses, net of the related ACL, and have been classified as Level 3 assets. In 2022, the amount shown is the balance of individually evaluated loans reporting a specific allocation or that have been partially charged-off. All of these loans are considered collateral-dependent; therefore, all of Mid Penn’s impaired loans, whether reporting a specific allowance allocation or not, are considered collateral- dependent. Mid Penn utilized Level 3 inputs such as independent appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable. Appraisals may be adjusted downward by management for qualitative factors such as economic conditions and estimated liquidation expenses.

Foreclosed assets held for sale - Values are based on appraisals that consider the sales prices of property in the proximate vicinity.

(1)Long-term debt excludes finance lease obligations.

The Bank’s outstanding and unfunded credit commitments and financial standby letters of credit were deemed to have no significant fair value as of September 30, 2023 and December 31, 2022.

Note 8 - Commitments and Contingencies

Guarantees and commitments to extend credit

Mid Penn is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. The commitments include various guarantees and commitments to extend credit. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Mid Penn evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary upon extension of credit, is based on management’s credit evaluation of the customer. Standby letters of credit and financial guarantees written are conditional commitments to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Mid Penn had $63.8 million and $57.2 million of standby letters of credit outstanding as of September 30, 2023 and December 31, 2022, respectively. Mid Penn does not anticipate any losses because of these transactions. The amount of the liability as of September 30, 2023 and December 31, 2022 for payment under standby letters of credit issued was not considered material.

Mid Penn adopted FASB ASC Topic 326, effective January 1, 2023, which requires Mid Penn to estimate expected credit losses for OBS credit exposures which are not unconditionally cancellable. Mid Penn maintains a separate ACL on OBS credit exposures, including unfunded loan commitments and letters of credit, which is included in other liabilities on the accompanying Consolidated Balance Sheets.

The ACL - OBS is adjusted as a provision for OBS commitments in noninterest expense. The estimate includes consideration of the likelihood that funding will occur, an estimate of exposure at default that is derived from utilization rate assumptions using a non-modeled approach, and PD and LGD estimates that are derived from the same models and approaches for Mid Penn's other loan portfolio segments described in "Note 4 - Loans and Allowance for Credit Losses - Loans" above, as these unfunded commitments share similar risk characteristics with these loan portfolio segments.

The ACL - OBS at September 30, 2023 was $4.5 million compared to $85 thousand at December 31, 2022. On January 1, 2023 in conjunction with adopting ASC 326, Mid Penn recorded an additional $3.1 million of provision for OBS which was included in the adoption cumulative effect adjustment. Provision expense for OBS for the three months ended September 30, 2023 was $661 thousand. Provision expense for OBS for the nine months ended September 30, 2023 was $1.3 million.

Low-income housing project commitments

Mid Penn Bank has a limited partnership interest in a low-income housing project to construct 39 apartments and common amenities in Cumberland County, Pennsylvania. All of the units are expected to qualify for Federal LIHTC as provided for in Section 42 of the Internal Revenue Code of 1986, as amended. Mid Penn’s limited partner capital contribution commitment is expected to be $10.8 million, which will be paid in installments over the course of construction of the low-income housing facilities. The investment in the limited partnership will be reported in other assets on the balance sheet and amortized over a ten-year period. The project has been conditionally awarded $1.2 million in annual LIHTCs by the Pennsylvania Housing Finance Agency, with a total anticipated LIHTC amount of $12.0 million to be received by Mid Penn over the ten-year amortization period. Mid Penn’s commitment to purchase the limited partnership interest is conditional upon (i) the review and approval of all closing documents, (ii) an opinion letter for tax counsel to the Partnership that the project qualifies for the LIHTCs, and (iii) review and approval by Mid Penn of other documents it may deem necessary.

Mid Penn assumed a commitment, as a result of the Riverview Acquisition, to purchase a limited partnership interest in a low-income housing project to preserve and rehabilitate three buildings consisting of 17 apartments and two commercial shops in Schuylkill County, Pennsylvania. All the units are expected to qualify for LIHTCs. Mid Penn’s limited partner capital contribution commitment is expected to be $4.4 million, which will be paid in installments over the course of construction of the low-income housing facilities. The investment in the limited partnership will be reported in other assets on the balance sheet and amortized over a ten-year period. Additionally, the agreement commits Mid Penn to a construction

loan in the maximum principal amount of $3.5 million, which will bear interest at 5.5% annum with a term of twenty-four months. The project has been conditionally awarded $484 thousand in annual LIHTCs by the Pennsylvania Housing Finance Agency, with a total anticipated LIHTC amount of $4.8 million to be received by Mid Penn over the ten-year amortization period. Mid Penn’s commitment to purchase the limited partnership interest is conditional upon (i) the review and approval of all closing documents, (ii) an opinion letter for tax counsel to the Partnership that the project qualifies for the LIHTCs, and (iii) review and approval by Mid Penn of other documents it may deem necessary.

Litigation

Mid Penn is subject to lawsuits and claims arising out of its normal conduct of business. In the opinion of management, after consultation with legal counsel, the ultimate disposition of these matters is not expected to have a material adverse effect on the consolidated financial condition of Mid Penn.

Note 9 - Debt

Short-term FHLB and Correspondent Bank Borrowings

Total short-term borrowings were $139.0 million and $102.6 million as of September 30, 2023 and December 31, 2022, respectively. Short-term borrowings generally consist of federal funds purchased and advances from the FHLB with an original maturity of less than a year. Federal funds purchased from correspondent banks mature in one business day and reprice daily based on the Federal Funds rate. Advances from the FHLB are collateralized by the Bank’s investment in the common stock of the FHLB and by a blanket lien on selected loan receivables comprised principally of real estate secured loans within the Bank’s portfolio totaling $1.7 billion at September 30, 2023. The Bank had a short-term borrowing capacity from the FHLB as of September 30, 2023 up to the Bank’s unused borrowing capacity of $1.3 billion (equal to $1.7 billion of maximum borrowing capacity, less the aggregate amount of FHLB letter of credits securing public funds deposits, and other FHLB advances and obligations outstanding) upon satisfaction of any stock purchase requirements of the FHLB.

The Bank also has unused overnight lines of credit with other correspondent banks amounting to $35.0 million at September 30, 2023. No draws were made on these lines as of September 30, 2023 and December 31, 2022.

As a member of the FHLB, the Bank can access a number of credit products which are utilized to provide liquidity. The FHLB fixed rate instruments obtained by the Bank are secured under the terms of a blanket collateral agreement with the FHLB consisting of FHLB stock and qualifying Bank loan receivables, principally real estate secured loans. The Bank also obtains letters of credit from the FHLB to secure certain public fund deposits of municipality and school district customers who agree to use of the FHLB letters of credit as a legally allowable alternative to investment pledging. These FHLB letter of credit commitments totaled $226.0 million and $189.0 million as of September 30, 2023 and December 31, 2022, respectively.

Note 11 - Common Stock and Earnings Per Share

Treasury Stock Repurchase Program

Mid Penn adopted a treasury stock repurchase program ("Program") initially effective March 19, 2020, and renewed through May 11, 2024 by Mid Penn’s Board of Directors on May 11, 2023. The Program authorizes the repurchase of up to $15.0 million of Mid Penn’s outstanding common stock. Under the Program, Mid Penn conducts repurchases of its common stock through open market transactions (which may be by means of a trading plan adopted under SEC Rule 10b5-1) or in privately negotiated transactions. Repurchases under the Program are made at the discretion of management and are subject to market conditions and other factors. There is no guarantee as to the exact number of shares that Mid Penn may repurchase. The Program is able to be modified, suspended or terminated at any time, at Mid Penn’s discretion, based upon a number of factors, including liquidity, market conditions, the availability of alternative investment opportunities and other factors Mid Penn deems appropriate. The Program does not obligate Mid Penn to repurchase any shares.

During the three months ended September 30, 2023, Mid Penn did not repurchase any shares of common stock. As of September 30, 2023, Mid Penn had repurchased 412,722 shares of common stock at an average price of $22.92 per share under the Program. The Program had $5.5 million remaining available for repurchase as of September 30, 2023.

Dividend Reinvestment Plan

Under Mid Penn’s amended and restated DRIP, 300,000 shares of Mid Penn’s authorized but unissued common stock are reserved for issuance. The DRIP also allows for voluntary cash payments, within specified limits, to be used for the purchase of additional shares.

Equity Incentive Plans

On May 9, 2023, shareholders approved the 2023 Stock Incentive Plan, which authorizes Mid Penn to grant incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock, deferred stock units and performance shares. The 2023 Plan was established for employees and directors of Mid Penn and the Bank, selected by the Compensation Committee of the Board of Directors, to incentivize the further success of the Company, and replaces the 2014 Restricted Stock Plan. The aggregate number of shares of common stock of the Company available for issuance under the Plan is 350,000 shares.

As of September 30, 2023, a total of 217,514 restricted shares were granted under the 2014 Plan, of which 88,519 shares were unvested. The 2014 Plan shares granted and vested resulted in $324 thousand and $237 thousand in share-based compensation expense for the three months ended September 30, 2023 and 2022, respectively. For the nine months ended September 30, 2023 and 2022, the 2014 Plan shares granted and vested resulted in share-based compensation expense of $825 thousand and $694 thousand, respectively.

Share-based compensation expense relating to restricted stock is calculated using grant date fair value and is recognized on a straight-line basis over the vesting periods of the awards. Restricted shares granted to employees vest in equal amounts on the anniversary of the grant date over the vesting period and the expense is a component of salaries and benefits expense on the Consolidated Statement of Income. The employee grant vesting period is determined by the terms of each respective grant, with vesting periods generally between one and four years. Restricted shares granted to directors have a twelve-month vesting period, and the expense is a component of directors’ fees and benefits within the other expense line item on the Consolidated Statement of Income.

Overview

Mid Penn is a financial holding company, which generates the majority of its revenues through net interest income, or the difference between interest earned on loans and investments and interest paid on deposits and borrowings. Growth in net interest income is dependent upon balance sheet growth and maintaining or increasing the net interest margin, which is FTE net interest income as a percentage of average interest-earning assets. Mid Penn also generates revenue through fees earned on the various services and products offered to its customers and through gains on sales of assets, such as loans, investments and properties. Offsetting these revenue sources are provisions for credit losses - loans, non-interest expenses and income taxes.

The following table presents a summary of Mid Penn's earnings and selected performance ratios:

Summary of Financial Results

•Net Income Per Share - Mid Penn’s net income available to common shareholders ("earnings") for the three months ended September 30, 2023 was $9.2 million, or $0.56 per both common share basic and diluted, compared to earnings of $15.5 million, or $0.97 per both common share basic and diluted for the three months ended September 30, 2022. Mid Penn’s earnings for the nine months ended September 30, 2023 was $25.3 million, or $1.56 per both common share basic and diluted, compared to earnings of $39.1 million, or $2.45 per both common share basic and diluted for the nine months ended September 30, 2022. The results for the nine months ended September 30, 2023 were impacted by expenses related to the Brunswick Acquisition and lower mortgage banking revenue.

◦Net Interest Margin - For the third quarter of 2023, Mid Penn’s net interest margin was 3.16% versus 3.90% for the same period of 2022. For the nine months ended September 30, 2023, net interest margin was 3.33% versus 3.50% for the same period of 2022. The FOMC has increased rates six times during the 12 months since September 30, 2022. The yield on interest-earning assets for the third quarter of 2023 increased 107 basis points from the same period of 2022. The rate on interest-bearing liabilities increased 231 basis points from the same period of 2022. For the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022, the yield on interest-earning assets and rate on interest-bearing liabilities increased 135 basis points and 196 basis points, respectively.

◦Loan Growth - Total loans, net of unearned income, as of September 30, 2023 were $4.1 billion compared to $3.5 billion as of December 31, 2022, an increase of $631.5 million, or 18.0%. As mentioned above, $324.5 million, or 51.4%, of that growth was a result of the Brunswick Acquisition. The mix of commercial real estate and construction portfolios in relation to the total portfolio declined 3.0% and 1.5%, respectively from December 31, 2022 to September 30, 2023 while the proportion of the residential mortgage portfolio grew 6.0% over the same period. Non-owner occupied office commercial real estate exposure represents less than 8% of total loan balances and is primarily limited to suburban offices.

◦Deposit Growth - Total deposits increased $603.3 million, or 16.0%, from $3.8 billion at December 31, 2022, to $4.4 billion at September 30, 2023. The Brunswick Acquisition contributed $282.6 million of additional deposits on the acquisition date. Noninterest bearing deposits increased 1.4% to $804.8 million at September 30, 2023 from $793.9 million at December 31, 2022 and represent 18.4% of total deposits at September 30, 2023. At September 30, 2023, deposits that are uninsured and not collateralized totaled $1.2 billion or 27.0% of total deposits compared to $890.9 or 20.8% at June 30, 2023.

•Asset Quality - Mid Penn adopted CECL on January 1, 2023. Its ACL at September 30, 2023 was $34.0 million, or 0.82% of total loans, as compared to $19.0 million, or 0.54% of total loans at December 31, 2022.

◦Net Charge-offs/Recoveries - Mid Penn had net charge-offs of $11 thousand and net recoveries of $54 thousand for the three months ended September 30, 2023 and 2022, respectively. For the nine months ended September 30, 2023, net charge-offs were $294 thousand compared to net recoveries of $108 thousand for the same period of 2022.

◦Non-performing assets - Total non-performing assets were $14.4 million at September 30, 2023, an increase compared to non-performing assets of $8.6 million at December 31, 2022. The increase was partially a result of $3.9 million of non-accrual loans acquired from Brunswick.

◦Provision for credit losses - loans - The PCL - loans was $1.4 million for the three months ended September 30, 2023 compared to $1.6 million for the same period of 2022. For the nine months ended September 30, 2023 and 2022, the PCL - loans was $3.1 million and $3.8 million, respectively.

•Noninterest Income - Noninterest income totaled $5.3 million for the three months ended September 30, 2023 and $6.0 million for the three months ended September 30, 2022. For the nine months ended September 30, 2023, noninterest income totaled $14.9 million, compared to $16.9 million for the nine months ended September 30, 2022. The decrease was primarily attributable to lower mortgage banking and hedging activity.

•Noninterest Expense - Noninterest expense totaled $29.9 million for the third quarter of 2023, an increase of $5.2 million, or 20.9%, compared to noninterest expense of $24.7 million for the same period of 2022. Noninterest expense totaled $91.5 million for the nine months ended September 30, 2023, an increase of $17.1 million, or 23.0%, compared to noninterest expense of $74.4 million for the same period of 2022.

•Liquidity - Current liquidity, including borrowing capacity, enhanced to nearly $1.31 billion or 110.5% of uninsured and uncollateralized deposits, or approximately 29.8% of total deposits.

Critical Accounting Estimates

The 2022 Annual Report includes a summary of critical accounting estimates that Mid Penn considers to be most important to the presentation of its financial condition and results of operations, because they require management’s most difficult judgments as a result of the need to make estimates about the effects of matters that are inherently uncertain.

The following discussion is regarding the critical accounting estimates related to the application of CECL and business combinations.

Allowance for Credit Losses

In accordance with CECL, the ACL, which includes both the ACL - loans and the ACL for OBS credit exposures, is calculated with the objective of maintaining a reserve for current expected credit losses over the remaining expected life of the portfolio. Management's determination of the appropriateness of the reserve is based on continuously monitoring and evaluating the loan portfolio, lending-related commitments, current as well as forecasted economic factors, and other relevant factors. The ACL - loans is an estimate of expected losses inherent within Mid Penn's existing loan portfolio.

The loan loss estimation process involves procedures to appropriately consider the unique characteristics of Mid Penn’s loan portfolio segments. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the allowance is complex and requires judgement by Management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the ACL and credit loss expense.

Mid Penn estimates the ACL using relevant available information, from internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Mid Penn uses a third-party software application to calculate the quantitative portion of the ACL using a methodology and assumptions specific to each loan pool. The qualitative portion of the allowance is based on general economic conditions and other internal and external factors affecting Mid Penn as a whole as well as specific loans. Factors considered include the following: lending process, concentrations of credit, and credit quality. The quantitative and qualitative portions of the allowance are added together to determine the total ACL, which reflects Management’s expectations of future conditions based on reasonable and supportable forecasts. As such, the calculation of ACL is inherently subjective and requires management to exercise significant judgment. The CECL estimate is highly sensitive to the economic forecasts used to develop the estimate.

While management uses the best information known to it in order to make ACL valuations, adjustments to the ACL may be necessary based on changes in economic and other conditions, changes in the composition of the loan portfolio, or changes in accounting guidance. In times of economic slowdown, either local, regional or national, the risk inherent in the loan portfolio could increase resulting in the need for additional provisions to the ACL in future periods. An increase could also be necessitated by an increase in the size of the loan portfolio or in any of its components even though the credit quality of the overall portfolio may be improving.

For further discussion of the methodology used in the determination of the ACL, refer to "Note 1, Summary of Significant Accounting Policies", "Note 3 - Investment Securities", "Note 4 - Loans and Allowance for Credit Losses - Loans" and "Note 8 - Commitments and Contingencies" to the Consolidated Financial Statements. To the extent actual outcomes differ from management estimates, additional PCL may be required that would adversely impact earnings in future periods.

Business Combinations

Assets acquired and liabilities assumed in business combinations are measured at fair value as of the acquisition date. In many cases, determining the fair value of the assets acquired and liabilities assumed requires Mid Penn to estimate the timing and amount of cash flows expected to result from these assets and liabilities and to discount these cash flows at appropriate rates of interest, which require the utilization of significant estimates and judgment in accounting for the acquisition.

Net Interest Income

Net interest income, Mid Penn’s primary source of revenue, is the amount by which interest income on loans and investments exceeds interest incurred on deposits and borrowings. The amount of net interest income is affected by changes in interest rates and changes in the volume and mix of interest-sensitive assets and liabilities. Net interest income is also shown on a taxable-equivalent basis in total. Income from tax-exempt assets, primarily loans to or securities issued by state and local governments, is adjusted by an amount equivalent to the federal income taxes which would have been paid if the income received on these assets was taxable at the statutory rate of 21% for the periods presented.

Net interest income was $37.5 million for the three months ended September 30, 2023, a decrease of $2.1 million, or 5.4%, compared to the three months ended September 30, 2022. Mid Penn’s net interest margin for the three months ended September 30, 2023 was 3.16% compared to 3.90% for the three months ended September 30, 2022. The decrease to net interest margin was primarily a result of an increase in funding costs and growth in average interest-bearing liabilities, partially offset by higher yields on interest-earning assets and growth in average interest-earning assets. As previously noted, the FOMC has increased rates six times during the 12 months since September 30, 2022. The growth in both average interest-earning assets and average interest-bearing liabilities was largely the result of the Brunswick Acquisition. Both interest-earning assets and interest-bearing liabilities associated with the Brunswick Acquisition had substantially similar yields to the corresponding Mid Penn portfolios.

The higher yields and the growth in interest-earning assets contributed $11.4 million and $9.0 million, respectively, to the increase in interest income. The yield on interest-earning assets increased 107 bps to 5.35%, for the third quarter of 2023 compared to 4.28% for the third quarter of 2022. Average interest-earning assets increased $699.6 million, or 17.5%, during the third quarter of 2023 compared to the same period of 2022.

Average investment securities decreased $7.4 million and the yield on those investment securities increased 26 bps during the third quarter of 2023 compared to the third quarter of 2022, reducing interest income due to volume by $46 thousand

offset by increased rates contributing $513 thousand to interest income. Average loans increased $815.9 million, and the yield on those loans increased 102 bps contributing $9.7 million and $10.6 million, respectively, to the increase in interest income.

Interest expense increased $22.3 million during the third quarter of 2023 compared to the third quarter of 2022. The rate of interest-bearing liabilities increased from 0.48% for the third quarter of 2022 to 2.79% for the third quarter of 2023. The increase in the rate was primarily a result of a shift in the mix of deposits from demand, money market and savings to higher yielding time deposits. Mid Penn continued to offer higher rates to both retain and attract deposits. In addition, average short-term borrowings of $64.3 million were used to help fund loan growth, contributing $1.6 million to interest expense during the third quarter of 2023.

Net interest income was $110.0 million for the nine months ended September 30, 2023, an increase of $717 thousand, or 0.7%, compared to the same period of September 30, 2022. Mid Penn’s net interest margin for the nine months ended September 30, 2023 was 3.33% compared to 3.50% for the same period of September 30, 2022. The decrease to net interest margin was primarily a result of growth in average interest-earning assets and higher yields on interest-earning assets, more than offset by higher funding costs and growth in average interest-bearing liabilities. The growth in both average interest-earning assets and average interest-bearing liabilities was impacted by the Brunswick Acquisition during the second quarter of 2023. As mentioned above, both interest-earning assets and interest-bearing liabilities associated with the Brunswick Acquisition had substantially similar yields to the corresponding Mid Penn portfolios.

The higher yields and the growth in interest-earning assets contributed $31.3 million and $20.1 million, respectively, to the increase in interest income. The yield on interest-earning assets increased 135 bps to 5.16%, for the nine months ended September 30, 2023 compared to 3.81% for the same period of 2022. Average interest-earning assets increased $239.4 million, or 5.74%, during the nine months ended September 30, 2023 compared to the same period of 2022.

Interest expense increased $50.6 million during the first nine months of 2023 compared to the same period of 2022. The rate of interest-bearing liabilities increased from 0.41% for the first nine months of 2022 to 2.37% for the first nine months of 2023. The increase in the rate was primarily a result of a shift in the mix of deposits from demand, money market and savings to higher yielding time deposits. The rate on average interest-bearing deposits increased 190 bps contributing $44.0 million to the increase in interest expense during the nine months ended September 30, 2023 compared to the same period in 2022. In addition, average short-term borrowings of $93.2 million were used to help fund loan growth, contributing $4.6 million to interest expense during the nine months ended September 30, 2023 compared to the same period in 2022.

Provision for Credit Losses - Loans

On January 1, 2023, Mid Penn adopted ASU 2016-13, Financial Instruments - Credit Losses (ASC Topic 326): Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss methodology, and is referred to as CECL. The PCL was $1.4 million for the three months ended September 30, 2023 compared to $1.6 million for the three months ended September 30, 2022. The PCL was $3.1 million for the nine months ended September 30, 2023 compared to $3.8 million for the nine months ended September 30, 2022. The PCL for the nine months ended September 30, 2023 includes an initial provision for credit losses on non-PCD loans acquired in the Brunswick Acquisition of $2.0 million. The provision for both periods ended September 30, 2022 reflect the application of the incurred loss method for estimating credit losses.

Noninterest Income

Noninterest income for the three months ended September 30, 2023 was $5.3 million and $6.0 million for the three months ended September 30, 2022. The following table and explanations that follow provide additional analysis of noninterest income.

Noninterest income and variance analysis:

			Three Months Ended September 30,
(Dollars in Thousands)			2023						2022						$ Variance						% Variance

Earnings from cash surrender value of life insurance			278						250						28						11.2
Other			1,743						1,518						225						14.8
Total			$	5,346					$	5,963					$	(617)					(10.3		%)

Fiduciary and wealth management income declined $433 thousand or 25% during the third quarter of 2023. The decline was due to the timing of trust related activities which are often unpredictable.

Mortgage banking and mortgage hedging income declined significantly for the three months ending September 30, 2023 compared to the three months ending September 30, 2022 due to mortgage volumes. As mortgage rates have risen, demand for mortgages have slowed significantly. As such, it is more difficult to properly hedge lower volumes within the mortgage pipeline.

Other noninterest income increased $225 thousand to $1.7 million from $1.5 million for the three months ended September 30, 2023 compared to the three months ended September 30, 2022. The increase was primarily due to growth within insurance offerings as a result of an acquisition which occurred at the end of 2022.

Salaries and employee benefits were $15.3 million for the three months ended September 30, 2023, an increase of $1.7 million, or 12.3% versus the same period in 2022, with the increase attributable to the addition of staff from the Brunswick Acquisition and severance costs.

Software licensing and utilization costs and equipment expenses increased as a result of the Brunswick Acquisition.

FDIC assessment increased $1.4 million for the third quarter of 2023 compared to the third quarter of 2022 as a result of a lower capital ratios following the Brunswick acquisition leading to a higher assessment rate.

The decrease in the provision was the result of lower net income before taxes in both periods of 2023 compared to the same periods of 2022. The provision for income taxes for the three and nine months ended September 30, 2023 reflects a combined Federal and State effective tax rate of 19.8% and 16.5%, respectively, compared to 19.0% for both periods in 2022. The decrease in the effective tax rates in 2023 compared to 2022 was a result of recalculating Mid Penn's deferred tax assets as a result of now doing business in New Jersey due to the Brunswick Acquisition and receiving a benefit in state tax expense. Generally, Mid Penn’s effective tax rate is below the federal statutory rate due to earnings on tax-exempt loans, investments, and earnings from the cash surrender value of life insurance, as well as the impact of federal income tax credits, including those awarded from Mid Penn’s low-income housing investments. The realization of Mid Penn’s deferred tax assets is dependent on future earnings. Mid Penn currently anticipates that future earnings will be adequate to fully realize the currently recorded deferred tax assets.

Credit Quality, Credit Risk, and Allowance for Credit Losses

Mid Penn adopted FASB ASC Topic 326, in accordance with the amendments of FASB ASU 2016-13, effective January 1, 2023. The guidance in FASB ASC 326 replaces Mid Penn’s previous incurred loss methodology with a methodology that reflects the current expected credit losses and requires consideration of a broader range of reasonable and supportable information to determine credit losses. Mid Penn’s ACL methodology for loans is based upon guidance within FASB ASC Subtopic 326-20, "Financial Instruments – Credit Losses – Measured at Amortized Cost," as well as regulatory guidance from the FDIC, the Bank's primary federal regulator. The ACL is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. Credit quality within the loan portfolio is continuously monitored by management and is reflected within the ACL for loans. The ACL is an estimate of expected losses inherent within Mid Penn’s existing loan portfolio. The ACL is adjusted through the provision for credit losses and reduced by the charge off of loan amounts, net of recoveries.

The loan loss estimation process involves procedures to appropriately consider the unique characteristics of Mid Penn’s loan portfolio segments. When computing allowance levels, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Evaluations of the portfolio and individual credits are inherently subjective, as they require estimates, assumptions and judgments as to the facts and circumstances of particular situations. Determining the appropriateness of the allowance is complex and requires judgement by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense.

For a complete description of Mid Penn’s ACL methodology and the quantitative and qualitative factors included in the calculation, please see "Note 4 – Loans and Allowance for Credit Losses – Loans" included in Part I. Item 1. – Financial Statements of this report.

Upon the adoption of FASB ASC Topic 326 on January 1, 2023, Mid Penn recorded an overall increase of $15.0 million to the ACL on January 1, 2023 as a result of the adoption of CECL. Retained earnings decreased $11.5 million and deferred tax assets increased by $3.1 million. Included in the $15.0 million increase to the ACL was $3.1 million for certain OBS credit exposures that were previously recognized in other liabilities before the adoption of CECL. The ACL and the related PCL for the nine months ended September 30, 2022 reflect Mid Penn’s application of the incurred loss method for estimating credit losses.

Changes in the ACL are summarized as follows:

			Three Months Ended September 30,												Nine Months Ended September 30,
(Dollars in thousands)			2023						2022						2023						2022
Balance, beginning of period			$	32,588					$	16,876					$	18,957					$	14,597

Ratio of ACL - loans to net loans at end of period			0.82		%				0.56		%				0.82		%				0.56		%

(1) Includes a $2.0 million initial provision for credit losses on non-PCD loans acquired in the Brunswick Acquisition.

The ratio of allowance for credit losses to total loans was 0.82% at September 30, 2023 compared to 0.56% at September 30, 2022. The allowance at September 30, 2022 reflects Mid Penn’s application of the incurred loss method for estimating credit losses.

Total nonperforming assets were $14.4 million at September 30, 2023, an increase compared to nonperforming assets of $8.6 million at December 31, 2022. The increase since December 31, 2022 was primarily the result of the addition of $3.9 million of non-accrual loans from the Brunswick Acquisition. In addition, one relationship moved to non-accrual during the first quarter of 2023 and is collateralized in excess of the outstanding loan balances based on a current appraisal of the collateral.

Goodwill

Mid Penn evaluates goodwill annually for impairment unless events occur which indicate that impairment is possible, a triggering event. In response to bank failures during the late first and early second quarters of 2023, Management performed a Step 1 Goodwill analysis as of May 31, 2023, given that the decline in the price of Mid Penn's stock below its book value following these events was deemed a triggering event. At September 30, 2023, Mid Penn had goodwill of $130.0 million and Mid Penn's stock continues to trade below book value. Management has not noted any factors either internally or externally which would indicate that a triggering event has occurred during the third quarter of 2023 warranting an additional impairment test. Factors considered include actual earnings in relation to forecasted earnings, liquidity levels, changes in deposit balances, and credit quality, among others. Management will continue to monitor internal metrics and macroeconomic trends to determine if there is likelihood of Goodwill impairment. Additionally, our annual impairment test will be conducted as of October 31, 2023.

Deposits, Borrowings and Subordinated Debt

Total deposits increased $603.3 million, or 16.0%, from $3.8 billion on December 31, 2022, to $4.4 billion at September 30, 2023. The Brunswick Acquisition contributed $282.6 million to the deposit growth. The remaining growth was primarily due to an increase of $553.2 million, or 84.0%, in time deposits as the result of rate increases, partially offset by decreases in interest-bearing transaction accounts.

Total short-term borrowings increased $36.4 million, or 35.4%, from December 31, 2022 in order to fund loan growth. Total long-term borrowings were $59.0 million at September 30, 2023, an increase of $54.6 million from December 31, 2022, of which $30.0 million was a result of the Brunswick Acquisition and $25.0 million was an additional borrowing entered into by Mid Penn. In April of 2023, Mid Penn redeemed its $10.0 million subordinated debt issued in December of 2017. See "Note 10 - Subordinated Debt and Trust Preferred Securities" included in Part I. Item 1. – Financial Statements of this report.

Liquidity

Mid Penn’s objective is to maintain adequate liquidity to meet funding needs at a reasonable cost and to provide contingency plans to meet unanticipated funding needs or a loss of funding sources, while minimizing interest rate risk. Adequate liquidity provides resources for credit needs of borrowers, for depositor withdrawals, and for funding corporate operations. Sources of liquidity are as follows:

•a growing core deposit base;

•proceeds from the sale or maturity of investment securities;

•payments received on loans and mortgage-backed securities;

•overnight correspondent bank borrowings on various credit lines; and

•borrowing capacity available from the FHLB and the Federal Reserve Discount Window available to Mid Penn.

Mid Penn believes its core deposits are generally stable even in periods of changing interest rates. Liquidity is measured and monitored daily, allowing management to better understand and react to balance sheet trends. These measurements indicate that liquidity generally remains stable and exceeds our minimum defined levels of adequacy. Other than the trends of continued competitive pressures and volatile interest rates, and the uncertain impact of the current inflationary environment, there are no known demands, commitments, events, or uncertainties that will result in, or that are reasonably likely to result in, liquidity increasing or decreasing in any material way.

On at least a quarterly basis, a comprehensive liquidity analysis is reviewed by the Asset Liability Committee and Board of Directors. The analysis provides a summary of the current liquidity measurements, projections, and future liquidity positions given various levels of liquidity stress. Management also maintains a detailed Contingency Funding Plan designed to respond to overall stress in the financial condition of the banking industry or a prospective liquidity problem specific to Mid Penn.

The Consolidated Statements of Cash Flows provide additional information. Mid Penn’s operating activities during the nine months ended September 30, 2023 provided $36.4 million of cash, mainly due to net income. Cash used in investing activities during the nine months ended September 30, 2023 was $306.5 million, mainly the result of the net increase in loans. Cash provided by financing activities during the nine months ended September 30, 2023 totaled $327.4 million, primarily the result of an increase in net deposits. The net cash received from the Brunswick Acquisition totaled $1.1 million.

Regulatory Capital

Mid Penn and the Bank are subject to regulatory capital requirements administered by banking regulators. Failure to meet minimum capital requirements can trigger certain mandatory, and possibly additional discretionary, actions by the regulators that if, undertaken, could have a direct material effect on Mid Penn's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities, and certain off-balance sheet items as calculated under regulatory account practices. The Bank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Minimum regulatory capital requirements established by Basel III rules require Mid Penn and the Bank to:

•Meet a minimum Common Equity Tier I capital ratio of 4.5% of risk-weighted assets;

•Meet a minimum Tier I capital ratio of 6.0% of risk-weighted assets;

•Meet a minimum Total capital ratio of 8.0% of risk-weighted assets;

•Meet a minimum Tier I leverage capital ratio of 4.0% of average assets;

•Maintain a "capital conservation buffer" of 2.5% above the minimum risk-based capital requirements, which must be maintained to avoid restrictions on capital distributions and certain discretionary bonuses; and

•Comply with the definition of capital to improve the ability of regulatory capital instruments to absorb losses.

The Basel III Rules use a standardized approach for risk weightings that expands the risk-weighting for assets and off-balance sheet exposures from the previous 0%, 20%, 50% and 100% categories to a much larger and more risk-sensitive

55

MID PENN BANCORP, INC.

number of categories, depending on the nature of the assets and off-balance sheet exposures and resulting in higher risk weightings for a variety of asset categories.

Banks are evaluated for capital adequacy by regulatory supervisory agencies based on the ratio of capital to risk-weighted assets and total assets. The minimum capital to risk-weighted assets requirements, including the capital conservation buffers, which became effective for Mid Penn and the Bank on January 1, 2016, are illustrated below. At September 30, 2023, regulatory capital ratios for both Mid Penn and the Bank met the definition of a "well-capitalized" institution under the regulatory framework for prompt corrective action, and exceeded the minimum capital requirements under Basel III.

Mid Penn maintained the following regulatory capital ratios in comparison to regulatory requirements:

						September 30, 2023						December 31, 2022						Regulatory Minimum for Capital Adequacy						Fully Phased-In, with Capital Conversation Buffers
Tier I Leverage Capital (to Average Assets)						8.37		%				9.57		%				4.00		%				4.00		%
Common Equity Tier I (to Risk-Weighted Assets)						9.74						11.18						7.00						7.00
Tier I Risk-Based Capital (to Risk-Weighted Assets)						9.74						11.18						8.50						8.50
Total Risk-Based Capital (to Risk-Weighted Assets)						11.70						13.19						10.50						10.50

As of September 30, 2023 and December 31, 2022, Mid Penn and the Bank met all capital adequacy requirements and the Bank was considered "well-capitalized". However, future changes in regulations could increase capital requirements and may have an adverse effect on capital resources.

Shareholders' Equity

Shareholders' equity, or capital, is evaluated in relation to total assets and the risk associated with those assets, and the desire to collectively maintain and enhance shareholders’ value, and satisfactorily address regulatory capital requirements. Accordingly, capital management has been, and will continue to be, of paramount importance to Mid Penn.

Shareholders’ equity increased by $16.6 million, or 3.2%, from $512.1 million as of December 31, 2022 to $528.7 million as of September 30, 2023, primarily due to the $18.1 million in common stock issued to Brunswick shareholders, earnings of $25.3 million, partially offset by the $11.5 million reduction to retained earnings as a result of the adoption of CECL on January 1, 2023, stock repurchases of $4.6 million and dividends declared of $9.7 million.

ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As a financial institution, Mid Penn’s primary source of market risk is interest rate risk. Interest rate risk is the exposure to fluctuations in Mid Penn’s future earnings, earnings at risk, resulting from changes in interest rates. This exposure or sensitivity is a function of the repricing characteristics of Mid Penn's portfolio of assets and liabilities. Each asset and liability reprices either at maturity or during the life of the instrument. Interest rate sensitivity is measured as the difference between the volume of assets and liabilities that are subject to repricing in a future period of time.

The principal purpose of asset-liability management is to maximize current and future net interest income within acceptable levels of interest rate risk while satisfying liquidity and capital requirements. Net interest income is increased by increasing the net interest margin and by volume growth. Thus, the goal of interest rate risk management is to maintain a balance between risk and reward such that net interest income is maximized while risk is maintained at an acceptable level.

Mid Penn utilizes an asset-liability management model to measure the impact of interest rate movements on its interest rate sensitivity position. Mid Penn’s management also reviews the traditional maturity gap analysis regularly. Mid Penn does not always attempt to achieve an exact match between interest sensitive assets and liabilities because it believes that an actively managed amount of interest rate risk is inherent and appropriate in the management of Mid Penn’s profitability.

Modeling techniques and simulation analysis involve assumptions and estimates that inherently cannot be measured with complete precision. Key assumptions in the analyses include maturity and repricing characteristics of assets and liabilities, prepayments on amortizing assets, non-maturing deposit sensitivity, and loan and deposit pricing. These assumptions are inherently uncertain due to the timing, magnitude and frequency of rate changes and changes in market conditions and management strategies, among other factors. However, the analyses are useful in quantifying risk and provide a relative gauge of Mid Penn’s interest rate risk position over time.

Management reviews interest rate risk on a quarterly basis. This analysis includes earnings scenarios whereby interest rates are increased or decreased by 100, 200, 300 and 400 bps. These scenarios, detailed in the table below, indicate that Mid Penn would experience enhanced net interest income over a one-year time frame due to upward interest rate changes and due to a reduction in interest rates to 200 bps. A reduction in rates greater than 200 bps would result in a decline in net interest income over a one-year time frame; however, actual results could vary significantly from the calculations prepared by management. At September 30, 2023, all interest rate risk levels according to the model were within the tolerance limits of the Board-approved policy.

Change in Basis Points						% Change in Net Interest Income						Policy Risk Limit
400						2.10%						≥ -25%
300						1.70%						≥ -20%
200						1.10%						≥ -15%
100						0.60%						≥ -10%
(100)						-0.20%						≥ -10%
(200)						-0.70%						≥ -15%
(300)						(1.90)%						≥ -20%
(400)						(5.10)%						≥ -25%

ITEM 4 – CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Mid Penn maintains controls and procedures designed to ensure that information required to be disclosed in the reports that Mid Penn files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized, and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Based upon their evaluation of those controls and procedures as of September 30, 2023, Mid Penn’s management, with the participation of the Principal Executive Officer and Principal Financial Officer, concluded that the disclosure controls and procedures were effective as of such date.

(1)None.

(2)None.

Mid Penn adopted a treasury stock repurchase program ("Program") initially effective March 19, 2020, and renewed through May 11, 2024 by Mid Penn’s Board of Directors on May 11, 2023. The Program authorizes the repurchase of up to $15.0 million of Mid Penn’s outstanding common stock. Under the Program, Mid Penn conducts repurchases of its common stock through open market transactions (which may be by means of a trading plan adopted under SEC Rule 10b5-1) or in privately negotiated transactions. Repurchases under the Program are made at the discretion of management and are subject to market conditions and other factors. There is no guarantee as to the exact number of shares that Mid Penn may repurchase. The Program is able to be modified, suspended or terminated at any time, at Mid Penn’s discretion, based upon a number of factors, including liquidity, market conditions, the availability of alternative investment opportunities and other factors Mid Penn deems appropriate. The Program does not obligate Mid Penn to repurchase any shares. During the three months ended September 30, 2023, Mid Penn did not repurchase any shares of common stock.
