ACNB CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Note 1 - Basis of Presentation and Nature of Operations
ACNB Corporation (the Corporation or ACNB), headquartered in Gettysburg, Pennsylvania, provides banking, insurance, and financial services to businesses and consumers through its wholly-owned subsidiaries, ACNB Bank (Bank) and ACNB Insurance Services, Inc. The Bank engages in full-service commercial and consumer banking and wealth management services, including trust and retail brokerage, through its 26 community banking offices, including 17 community banking office locations in Adams, Cumberland, Franklin and York Counties, Pennsylvania, and 9 community banking office locations in Carroll and Frederick Counties, Maryland. There are also loan production offices situated in Lancaster and York, Pennsylvania, and Hunt Valley, Maryland.
ACNB Insurance Services, Inc. is a full-service insurance agency based in Westminster, Maryland, with additional locations in Jarrettsville, Maryland, and Gettysburg, Pennsylvania. The agency offers a broad range of property, casualty, health, life and disability insurance to both individual and commercial clients.
The Corporation’s primary sources of revenue are interest income on loans and investment securities and fee income on its products and services. Expenses consist of interest expense on deposits and borrowed funds, provisions for credit losses, and other operating expenses.
The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (US GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly ACNB Corporation’s statement of condition, statement of income, comprehensive (loss) income, changes in stockholders’ equity, and cash flows. All such adjustments are of a normal recurring nature.
The accounting policies followed by the Corporation are set forth in Note A to the Corporation’s consolidated financial statements in the 2022 ACNB Corporation Annual Report on Form 10-K, filed with the SEC on March 3, 2023. It is suggested that the consolidated financial statements contained herein be read in conjunction with the consolidated financial statements and notes included in the Corporation’s Annual Report on Form 10-K. The results of operations for the three and nine month periods ended September 30, 2023, are not necessarily indicative of the results to be expected for the full year.
Certain reclassifications have been made to the prior period financial statements to conform to the current period presentation. Reclassifications had no material effect on prior year net income or stockholders’ equity.
The Corporation 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 the consolidated financial statements. The evaluation was conducted through the date these consolidated financial statements were issued.
Recently Adopted Accounting Standards
In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”, universally referred to as Current Expected Credit Loss (CECL). The amendments in this ASU, among other things, require the measurement of all expected credit losses for financial assets, including but not limited to loans, held to maturity securities and purchased financial assets, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied previously are still permitted, although the inputs to those techniques changed to reflect the full amount of expected credit losses. In addition, Topic 326 amends the accounting for credit losses on certain other debt securities. The Corporation did not record any allowance for credit losses on its debt securities as a result of adopting Topic 326. For smaller reporting companies, such as the Corporation, this standard (Topic 326) was effective as of January 1, 2023.
The Bank’s CECL Committee, which includes members from Credit Administration, Accounting/Finance, Risk Management and Internal Audit, has oversight by the Chief Executive Officer, Chief Financial Officer, and Chief Credit Officer. The Bank engaged a third-party to assist in developing the CECL model and to assist with evaluation of data and methodologies related to this standard.
7

As part of its process of adopting CECL, management implemented a third party software solution and determined appropriate loan segments, methodologies, model assumptions and qualitative components. The Bank’s CECL model includes portfolio loan segmentation based upon similar risk characteristics and both a quantitative and qualitative component of the calculation which incorporates a forecasting component of certain economic variables. The Bank’s implementation plan also includes the assessment and documentation of appropriate processes, policies and internal controls. Management had a third party independent consultant review and validate the CECL model.
The ultimate impact of adopting Topic 326, and at each subsequent reporting period, is highly dependent on credit quality, macroeconomic forecasts and conditions, composition of the loans and securities portfolio, along with other management judgments. The Corporation adopted Topic 326 using the modified retrospective method. Results for reporting periods beginning after January 1, 2023 are presented under Topic 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP.
In connection with the adoption of Topic 326, the Corporation made changes to the loan portfolio segments to align with the methodology applied in determining the allowance under CECL. Refer to Note 8 — “Loans and Allowance for Credit Losses” in the Notes to Consolidated Financial Statements for further discussion of these portfolio segments.
The adoption of Topic 326 resulted in a Day 1 adjustment of $3.3 million, including an increase to the allowance for credit losses (ACL) of $1.6 million and a $1.6 million reserve on unfunded loan commitments recorded in the liabilities section on the Consolidated Statements of Condition on January 1, 2023. As of January 1, 2023, the Corporation recorded a cumulative effect adjustment of $2.4 million to decrease retained earnings related to the adoption of Topic 326. Upon CECL adoption the Corporation elected to implement the regulatory agencies’ capital transition relief over the permissible three-year period. The following table illustrates the impact of Topic 326:

|  | January 1, 2023

The ACL represents an amount which, in management’s judgment, is adequate to absorb expected losses on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The ACL is measured and recorded upon the initial recognition of a financial asset. The ACL is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provision for credit losses, which is recorded as a current period operating expense.
Determination of an appropriate ACL is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness of the ACL is reviewed quarterly by management.
8

Management believes it uses relevant information available to make determinations about the ACL and that it has established the existing allowance in accordance with GAAP. However, the determination of the ACL requires significant judgment, and estimates of expected losses in the loan portfolio can vary significantly from the amounts actually observed. While management uses available information to recognize expected losses, future additions to the ACL may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes to the interest rate environment which may directly impact prepayment and curtailment rate assumptions, and changes in the financial condition of borrowers.
The adoption of CECL accounting did not result in a significant change to any other credit risk management and monitoring processes, including identification of past due or delinquent borrowers, nonaccrual practices or charge-off policy.
The Corporation’s methodology for estimating the ACL includes:
Segmentation. The Corporation’s loan portfolio is segmented by loan types that have similar risk characteristics and behave similarly during economic cycles.
Specific Analysis. A specific reserve analysis is applied to certain individually evaluated loans. These loans are evaluated quarterly generally based on collateral value, observable market value or the present value of expected future cash flows. A specific reserve is established if the fair value is less than the loan balance. A charge-off is recognized when the loss is quantifiable. Individually evaluated loans not specifically analyzed reside in the Quantitative Analysis.
Quantitative Analysis. The Corporation elected to use Discounted Cash Flow (DCF) and chose unemployment rate as the driving factor of their economic forecasts. In regards to unemployment rates, the Corporation elected to forecast economic factors over the period of the next four quarters. The Corporation chose not to extend beyond four quarters given the inherent risks associated with forecasting. The Corporation utilizes relevant third party forecasts as a basis and support for its own forecast. These forecasts are assumed to revert to the long-term average and utilized in the model to estimate the probability of default and loss given default through regression. The Corporation elected a reversion period of four quarters. The Corporation deemed four quarters to be a reasonable time period to ensure it did not include irrelevant information, but also not too short to introduce unnecessary volatility. Model assumptions include, but are not limited to the discount rate, prepayment speeds, funding rates, and curtailments. The product of the probability of default and the loss given default is the estimated loss rate, which varies over time. The estimated loss rate is applied within the appropriate periods in the cash flow model to determine the net present value. Net present value is also impacted by assumptions related to the duration between default and recovery. The reserve is based on the difference between the summation of the principal balances taking amortized costs into consideration and the summation of the net present values.
Qualitative Analysis. Based on management’s review and analysis of internal, external and model risks, management may adjust the model output. Management reviews the peaks and troughs of the model’s calibration, taking into account economic forecasts to develop guardrails that serve as the basis for determining the reasonableness of the model’s output and makes adjustments as necessary. This process challenges unexpected variability resulting from outputs beyond the model’s calibration that appear to be unreasonable. Additionally, management may adjust the economic forecast if it is incompatible with known market conditions based on management’s experience and perspective. The current expected losses of $1.6 million were recorded due to the adoption of CECL, which now incorporates the concept of lifetime losses.
Included in the allowance for unfunded commitments in the first quarter of 2023, was $1.6 million recorded upon Day 1 CECL adoption. Between the Day 1 CECL model and the model ended September 30, 2023, an additional $226,000 of provision was recognized, which resulted in a total allowance for unfunded commitments of $2.0 million at September 30, 2023.
In March 2022, the FASB issued ASU 2022-02, “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures.” ASU 2022-02 made certain targeted amendments specific to troubled debt restructurings (TDRs) by creditors and vintage disclosure related to gross write-offs. Upon adoption, the Corporation is required to apply the loan and refinancing and restructuring guidance to determine whether a modification results in a new loan or a continuation of an existing loan, rather than applying the recognition and measurement guidance for TDRs. The ASU also requires companies to disclose current-period gross write-offs by year of origination for financing receivables and net investment in leases within scope of Subtopic 326-20. ASU 2022-02 is effective March 31, 2023, for entities that have adopted ASU 2016-13, otherwise effective date is the same as ASU 2016-13. The Corporation adopted ASU 2016-13 on January 1, 2023 and simultaneously implemented ASU 2022-02.

Accounting Standards Pending Adoption
In December 2022, the FASB issued ASU 2022-06, “Deferral of the Sunset Date of Reference Rate Reform (Topic 848)”. This ASU extends the sunset date of ASC Topic 848 (Reference Rate Reform) to December 31, 2024, in response to the United Kingdom’s Financial Conduct Authority (FCA) extension of the intended cessation date of LIBOR in the United States. The Corporation evaluated the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s consolidated financial condition or results of operations.
Note 2 - Earnings Per Share and Restricted Stock
The Corporation has a simple capital structure. Basic earnings per share of common stock is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding less unvested restricted stock at the end of the period. Diluted earnings per share is calculated as net income available to common shareholders divided by the weighted average number of shares outstanding.

|  | Three Months Ended September 30, |  | Nine Months Ended September 30,
| 2023 |  | 2022 |  | 2023 |  | 2022
Weighted average shares outstanding (basic) |  | 8,517,917 |  |  | 8,587,826 |  |  | 8,518,006 |  |  | 8,658,972 |

Diluted |  | 1.06 |  |  | 1.20 |  |  | 3.23 |  |  | 2.95 |

Stock Incentive Plan
On May 1, 2018, shareholders approved and ratified the ACNB Corporation 2018 Omnibus Stock Incentive Plan, effective as of March 20, 2018, in which awards shall not exceed, in the aggregate, 400,000 shares of common stock, plus any shares that were authorized, but not issued, under the ACNB Corporation 2009 Restricted Stock Plan. The ACNB Corporation 2009 Restricted Stock Plan expired by its own terms after 10 years on February 24, 2019. No further shares may be issued under this plan. The remaining 174,055 shares were transferred to the ACNB Corporation 2018 Omnibus Stock Incentive Plan.
As of September 30, 2023, 100,746 shares were issued under this plan, of which 33,100 were unvested. Plan expense is recognized over the vesting period of the stock issued and resulted in $265 thousand and $116 thousand of compensation expense during the three months ended September 30, 2023 and 2022, respectively, and $1.0 million and $474 thousand of compensation expenses during the nine months ended September 30, 2023 and 2022, respectively.
Note 3 - Retirement Benefits
The components of net periodic benefit income related to the non-contributory, defined benefit pension plan were as follows:

|  | Three Months Ended September 30, |  | Nine Months Ended September 30,
In thousands |  | 2023 |  | 2022 |  | 2023 |  | 2022
Service cost |  | $ | 124 |  |  | $ | 194 |  |  | $ | 372 |  |  | $ | 582 |
Interest cost |  | 373 |  |  | 263 |  |  | 1,119 |  |  | 789 |
Expected return on plan assets |  | (663) |  |  | (784) |  |  | (1,989) |  |  | (2,352) |
Amortization of net loss |  | 98 |  |  | 102 |  |  | 294 |  |  | 305 |
Net Periodic Benefit Income |  | $ | (68) |  |  | $ | (225) |  |  | $ | (204) |  |  | $ | (676) |

The Corporation has determined that it will not be contributing to the defined benefit plan in 2023 based on current levels and expected returns on plan assets. Effective April 1, 2012, no inactive or former participant in the plan is eligible to again participate in the plan, and no employee hired after March 31, 2012, is eligible to participate in the plan.

Note 4 - Guarantees
The Corporation does not issue any guarantees that would require liability recognition or disclosure, other than its standby letters of credit. Standby letters of credit are written conditional commitments issued by the Corporation to guarantee the performance of a customer to a third party. Generally, all letters of credit, when issued, have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as those that are involved in extending loan facilities to customers. The Corporation generally holds collateral and/or personal guarantees supporting these commitments. The Corporation had $22.8 million in standby letters of credit as of September 30, 2023. Management believes that the proceeds obtained through a liquidation of collateral and the enforcement of guarantees would be sufficient to cover the potential amount of future payments required under the corresponding guarantees.
Note 5 - Accumulated Other Comprehensive Loss
The components of accumulated other comprehensive loss, net of taxes, are as follows:

In thousands |  | Unrealized Losses on Securities |  | Pension Liability |  | Accumulated Other Comprehensive Loss

Note 6 - Segment Reporting
The Corporation has two reporting segments, the Bank and ACNB Insurance Services, Inc. ACNB Insurance Services, Inc., is managed separately from the banking segment, which includes the Bank and related financial services that the Corporation offers through its banking subsidiary. ACNB Insurance Services, Inc., offers a broad range of property and casualty, life, and health insurance to both commercial and individual clients.

The Corporation adopted ASU 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” on January 1, 2023 and did not record an allowance for credit losses on its investment securities during the quarter ended September 30, 2023. The Corporation regularly reviews debt securities for expected credit loss using both qualitative and quantitative criteria, as necessary, based on the composition of the portfolio at period end. Management buys and sells securities from its available for sale portfolio due to general balance sheet and interest rate risk management.
Amortized cost and fair value at September 30, 2023, by contractual maturity, where applicable, are shown below. Expected maturities will differ from contractual maturities because issuers may have the right to call or prepay with or without penalties. Securities not due at a single maturity date are shown separately.

Consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process at September 30, 2023 and December 31, 2022, totaled $777 thousand and $1.1 million, respectively.
No additional funds are committed to be advanced in connection with individually evaluated loans.
Loan Modifications
On January 1, 2023, the Corporation adopted the accounting guidance in ASU 2022-02, which eliminates the recognition and measurement of troubled debt restructurings (TDRs). Due to the removal of the TDR designation, the Corporation evaluates all loan restructurings according to the accounting guidance for loan modifications to determine if the restructuring results in a new loan or a continuation of the existing loan. Loan modifications to borrowers experiencing financial difficulty that result in a direct change in the timing or amount of contractual cash flows include situations where there is principal forgiveness, interest rate reductions, other-than-insignificant payment delays, term extensions, and combinations of the above. Therefore, the disclosures related to loan restructurings are only for modifications that directly affect cash flows.
As of September 30, 2023, the Corporation had no modified loans or any commitments to lend any additional funds on modified loans. As of September 30, 2023, the Corporation had no loans that defaulted during the period and had been modified preceding the payment default when the borrower was experiencing financial difficulty at the time of modification. For purposes of this disclosure, a default occurs when, within 12 months of the original modification, either a full or partial charge-off occurs or the loan becomes 90 days or more past due.
Allowance for Credit Losses
The Corporation maintains an allowance for credit losses (ACL) at a level determined to be adequate to absorb expected credit losses associated with the Corporation’s financial instruments over the life of those instruments as of the balance sheet date. The Corporation develops and documents a systematic ACL methodology based on the following portfolio segments: 1) Commercial and Industrial, 2) Commercial Real Estate, 3) Commercial Real Estate Construction, 4) Residential Mortgage, and 5) Home Equity Lines of Credit. The Corporation’s loan portfolio is segmented by loan types that have similar risk characteristics and behave similarly during economic cycles. The segmentation in the CECL model is different from the segmentation in the incurred loss model, however there was minimal impact on the presentation of the financial statement disclosures. The following is a discussion of the key risks by portfolio segment that management assesses in preparing the ACL.
Commercial and Industrial Lending — The Corporation originates commercial and industrial loans primarily to businesses located in its primary market area and surrounding areas. These loans are used for various business purposes which include short-term loans and lines of credit to finance machinery and equipment purchases, inventory, and accounts receivable. Generally, the maximum term for loans extended on machinery and equipment is based on the projected useful life of such machinery and equipment. Most business lines of credit are written on demand and may be renewed annually.
Commercial and industrial loans are generally secured with short-term assets; however, in many cases, additional collateral such as real estate is provided as additional security for the loan. Loan-to-value maximum values have been established by the Corporation and are specific to the type of collateral. Collateral values may be determined using invoices, inventory reports, accounts receivable aging reports, collateral appraisals, etc.
In underwriting commercial and industrial loans, an analysis is performed to evaluate the borrower’s character and capacity to repay the loan, the adequacy of the borrower’s capital and collateral, as well as the conditions affecting the borrower. Evaluation of the borrower’s past, present and future cash flows is also an important aspect of the Corporation’s
16

analysis. Commercial loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions.
Commercial Real Estate Lending — The Corporation engages in commercial real estate lending in its primary market area and surrounding areas. The Corporation’s commercial loan portfolio is secured primarily by commercial retail space, office buildings, and hotels. Generally, commercial real estate loans have terms that do not exceed 20 years, have loan-to-value ratios of up to 80% of the appraised value of the property, and are typically secured by personal guarantees of the borrowers.
In underwriting these loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history, and the reliability and predictability of the cash flow generated by the property securing the loan. Appraisals on properties securing commercial real estate loans originated by the Corporation are performed by independent appraisers. Commercial real estate loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions and the complexities involved in valuing the underlying collateral.
Commercial Real Estate Construction Lending — The Corporation engages in commercial real estate construction lending in its primary market area and surrounding areas. The Corporation’s commercial real estate construction lending consists of commercial and residential site development loans, as well as commercial building construction and residential housing construction loans.
The Corporation’s commercial real estate construction loans are generally secured with the subject property. Terms of construction loans depend on the specifics of the project, such as estimated absorption rates, estimated time to complete, etc.
In underwriting commercial real estate construction loans, the Corporation performs a thorough analysis of the financial condition of the borrower, the borrower’s credit history, and the reliability and predictability of the cash flow generated by the project using feasibility studies, market data, etc. Appraisals on properties securing commercial real estate construction loans originated by the Corporation are performed by independent appraisers. Commercial real estate construction loans generally present a higher level of risk than other types of loans due primarily to the effect of general economic conditions and the uncertainties surrounding total construction costs.
Residential Mortgage Lending — One-to-four family residential mortgage loan originations, including home equity closed-end loans, are generated by the Corporation’s marketing efforts, its present customers, walk-in customers, and referrals. These loans originate primarily within the Corporation’s market area or with customers primarily from the market area.
The Corporation offers fixed-rate and adjustable-rate mortgage loans with terms up to a maximum of 30 years for both permanent structures and those under construction. The Corporation’s one-to-four family residential mortgage originations are secured primarily by properties located in its primary market area and surrounding areas. The majority of the Corporation’s residential mortgage loans originate with a loan-to-value of 80% or less. Loans in excess of 80% are required to have private mortgage insurance.
In underwriting one-to-four family residential real estate loans, the Corporation evaluates both the borrower’s financial ability to repay the loan as agreed and the value of the property securing the loan. Properties securing real estate loans made by the Corporation are appraised by independent appraisers. The Corporation generally requires borrowers to obtain an attorney’s title opinion or title insurance, as well as fire and property insurance (including flood insurance, if necessary) in an amount not less than the amount of the loan. The Corporation has not engaged in subprime residential mortgage originations. Residential mortgage loans are subject to risk due primarily to general economic conditions, as well as periods of weak housing markets.
Home Equity Lines of Credit Lending — The Corporation originates home equity lines of credit primarily within the Corporation’s market area or with customers primarily from the market area. Home equity lines of credit are generated by the Corporation’s marketing efforts, its present customers, walk-in customers, and referrals.
Home equity lines of credit are secured by the borrower’s primary residence with a maximum loan-to-value of 90% and a maximum term of 20 years. In underwriting home equity lines of credit, the Corporation evaluates both the value of the property securing the loan and the borrower’s financial ability to repay the loan as agreed. The ability to repay is determined by the borrower’s employment history, current financial condition, and credit background.
Home equity lines of credit generally present a moderate level of risk due primarily to general economic conditions, as well as periods of weak housing markets. Junior liens inherently have more credit risk by virtue of the fact that another financial institution may have a higher security position in the case of foreclosure liquidation of collateral to extinguish the debt. Generally, foreclosure actions could become more prevalent if the real estate markets are weak and property values deteriorate.
17

Consumer Lending — The Corporation offers a variety of secured and unsecured consumer loans, including those for vehicles and mobile homes and loans secured by savings deposits. These loans originate primarily within the Corporation’s market area or with customers primarily from the market area.
Consumer loan terms vary according to the type and value of collateral and the creditworthiness of the borrower. In underwriting consumer loans, a thorough analysis of the borrower’s financial ability to repay the loan as agreed is performed. The ability to repay is determined by the borrower’s employment history, current financial condition, and credit background.
Consumer loans may entail greater credit risk than residential mortgage loans or home equity lines of credit, particularly in the case of consumer loans which are unsecured or are secured by rapidly depreciable assets such as automobiles or recreational equipment. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance as a result of the greater likelihood of damage, loss or depreciation. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. Furthermore, the application of various federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans.
Credit Quality Indicators
The Corporation’s portfolio grading analysis estimates the capability of the borrower to repay the contractual obligations of the loan agreements as scheduled or at all. The Corporation’s internal credit risk grading system is based on debt service coverage, collateral values and other subjective factors. Non-commercial-purpose loans are defaulted to a pass grade until a loan migrates to past due status.
Special Mention – Considered “Other Assets Especially Mentioned”, these loans are currently protected, but are potentially weak. Loans in this rating category constitute an undue and unwarranted credit risk, but not to the point of justifying a classification of substandard. The credit risk may be relatively minor, yet constitutes an unwarranted risk in light of the circumstances surrounding a specific loan.
Substandard – Loans in this category are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual loans classified as substandard.
Doubtful – Loans in this category have all the weaknesses inherent in one classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonable specific pending factors which may work to strengthen the credit, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, or liquidation procedures, capital injection, perfecting liens on additional collateral, and refinancing plans.
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass-related loans.

All loans on nonaccrual status are individually evaluated in the specific analysis for the allowance for credit loss. An accruing TDR was included in the table above as of December 31, 2022. That loan was moved to performing status due to its loan repayment history upon the adoption of Topic 326.
During the three and nine months ended September 30, 2023, no material amount of interest income was recognized on individually evaluated loans subsequent to their classification as individually evaluated loans.
The following table presents the amortized cost basis of individually evaluated loans as of September 30, 2023. Changes in the fair value of the collateral for individually evaluated loans are reported as provision for credit losses or a reversal of provision for credit losses in the period of change.

Note 9 - Fair Value Measurements
Management uses its best judgment in estimating the fair value of the Corporation’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Corporation could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective reporting dates and have not been reevaluated or updated for purposes of these consolidated financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period end.
Fair value measurement and disclosure guidance defines fair value as the price that would be received to sell the asset or transfer the liability in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions.
Fair value measurement and disclosure guidance provides a list of factors that a reporting entity should evaluate to determine whether there has been a significant decrease in the volume and level of activity for the asset or liability in relation to normal market activity for the asset or liability. When the reporting entity concludes there has been a significant decrease in the volume and level of activity for the asset or liability, further analysis of the information from that market is needed and significant adjustments to the related prices may be necessary to estimate fair value in accordance with fair value measurement and disclosure guidance.
This guidance further clarifies that when there has been a significant decrease in the volume and level of activity for the asset or liability, some transactions may not be orderly. In those situations, the entity must evaluate the weight of the evidence to determine whether the transaction is orderly. The guidance provides a list of circumstances that may indicate that a transaction is not orderly. A transaction price that is not associated with an orderly transaction is given little, if any, weight when estimating fair value.
Fair value measurement and disclosure guidance establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
Level 2: 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: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).
An asset or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
For assets measured at fair value, the fair value measurements by level within the fair value hierarchy, and the basis of measurement used at September 30, 2023, and December 31, 2022, are as follows:

The following table presents additional quantitative information about assets measured at fair value on a nonrecurring basis for which the Corporation has utilized Level 3 inputs to determine fair value:

Individually evaluated loans |  | $ | 3,773 |  |  | Appraisal of collateral | (a) | Appraisal adjustments | (b) |  | (10) – (50)% |  | (48)%

(a) Fair value is generally determined through management’s estimate or independent third-party appraisals of the underlying collateral, which generally includes various Level 3 inputs which are not observable.
(b) Appraisals may be adjusted downward by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range of liquidation expenses and other appraisal adjustments are presented as a percentage of the appraisal. Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received, and/or age of the appraisal.
The following information should not be interpreted as an estimate of the fair value of the entire Corporation since a fair value calculation is only provided for a limited portion of the Corporation’s assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Corporation’s disclosures and those of other companies may not be meaningful.

Securities sold under repurchase agreements |  | $ | 33,106 |  |  | $ | 41,954 |
|  | $ | 33,106 |  |  | $ | 41,954 |

Borrowings with original maturities of one year or less are classified as short-term. Securities sold under repurchase agreements are comprised of customer repurchase agreements, which are sweep accounts with next-day maturities utilized by larger commercial customers to earn interest on their funds. Securities are pledged to these customers in an amount at least equal to the outstanding balance.
The Corporation had long-term debt outstanding as follows:

In thousands |  | September 30, 2023 |  | December 31, 2022
FHLB advances |  | $ | 100,000 |  |  | $ | — |
Trust preferred subordinated debt |  | 5,282 |  |  | 6,000 |
Subordinated debt |  | 15,000 |  |  | 15,000 |
|  | $ | 120,282 |  |  | $ | 21,000 |

The long-term FHLB advances mature between 2026 and 2028 and have a weighted average rate of 4.63%, with a prepayment penalty. The advances are collateralized by the assets defined in the security agreement and FHLB capital stock. Based on this collateral and ACNB’s holding of FHLB stock, ACNB is eligible to borrow up to $845.5 million, of which $745.2 million was available at September 30, 2023.
The trust preferred subordinated debt is comprised of debt securities issued by Frederick County Bancorp, Inc. (FCBI) in December 2006 and assumed by ACNB Corporation through the acquisition. FCBI completed the private placement of an aggregate of $6.0 million of trust preferred securities. The interest rate on the subordinated debentures is adjusted quarterly to
27

163 basis points over the three-month Chicago Mercantile Exchange (CME) Term Secured Overnight Financing Rate (SOFR) plus applicable tenor spread adjustment. The debenture has a provision for when LIBOR is no longer available. On September 15, 2023, the most recent interest rate reset date, the interest rate was adjusted to 7.30% for the period ending December 14, 2023. The trust preferred securities mature on December 15, 2036, and may be redeemed at par, at the Corporation’s option, on any interest payment date.
On March 30, 2021, ACNB Corporation (the Company) entered into Subordinated Note Purchase Agreements (Purchase Agreements) with certain institutional accredited investors and qualified institutional buyers (the Purchasers) pursuant to which the Company sold and issued $15.0 million in aggregate principal amount of its 4.00% fixed-to-floating rate subordinated notes due March 31, 2031 (the Notes). The Notes will bear interest at a fixed rate of 4.00% per year, from and including March 30, 2021 to, but excluding, March 31, 2026 or earlier redemption date. From and including March 31, 2026 to, but excluding the maturity date or earlier redemption date, the interest rate will reset quarterly at a variable rate equal to the then current 90-day average SOFR plus 329 basis points. As provided in the Notes, the interest rate on the Notes during the applicable floating rate period may be determined based on a rate other than the 90-day average SOFR. The Notes were issued by the Company to the Purchasers at a price equal to 100% of their face amount. The Notes have a stated maturity of March 31, 2031, are redeemable by the Company at its option, in whole or in part, on or after March 30, 2026, and at any time upon the occurrences of certain events.

CRITICAL ACCOUNTING ESTIMATES
The accounting estimates that the Corporation’s management deems to be most important to the portrayal of its financial condition and results of operations, and that require management’s most difficult, subjective or complex judgment, often result in the need to make estimates about the effect of such matters which are inherently uncertain. The following accounting estimates are deemed to be critical by management:
The allowance for credit losses (ACL) represents an amount which, in management’s judgment, is adequate to absorb expected credit losses on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The ACL is measured and recorded upon the initial recognition of a financial asset. The ACL is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provision for credit losses, which is recorded as a current period operating expense.
Determination of an appropriate ACL is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness of the ACL is reviewed quarterly by management.
Management believes it uses relevant information available to make determinations about the ACL and that it has established the existing allowance in accordance with GAAP. However, the determination of the ACL requires significant judgment, and estimates of expected credit losses in the loan portfolio can vary from the amounts actually observed. While management uses available information to recognize expected credit losses, future additions to the ACL may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes in the interest rate environment which may directly impact prepayment and curtailment rate assumption, and changes in the financial condition of borrowers.
RESULTS OF OPERATIONS
Quarter ended September 30, 2023, compared to Quarter ended September 30, 2022
Executive Summary
Net income for the three months ended September 30, 2023 was $9.0 million compared to net income of $10.3 million for the comparable quarter of the prior year, a decrease of $1.3 million or 12.4%. Basic and diluted earnings per share for the three months ended September 30, 2023 and 2022 were $1.06 and $1.20, respectively, an 11.7% decrease. The decrease in net income for the third quarter of 2023 was driven primarily by a decrease in net interest income and higher noninterest expenses, partially offset by an increase in noninterest income.
Net Interest Income
Net interest income totaled $21.7 million for the three months ended September 30, 2023 compared to $22.5 million for the comparable quarter of the prior year, a decrease of $775 thousand, or 3.4%. The decrease in net interest income was driven primarily by a decrease in earning assets, an increase in the cost of funds, and a decrease in purchase accounting accretion. Paycheck Protection Program (PPP) fees and purchase accounting accretion totaled $208 thousand for the three months ended September 30, 2023 compared to $853 thousand for the three months ended September 30, 2022. There were no PPP fees for the three months ended September 30, 2023 compared to $24 thousand for the comparable quarter of last year. The fully taxable equivalent (FTE) net interest margin for the three months ended September 30, 2023 was 4.01%, a 41 basis points increase from 3.60% for the comparable quarter of last year.
Average earning assets declined year-over-year driven primarily by a decrease in cash balances and investments, partially offset by loan growth. Interest income increased by $852 thousand for the three months ended September 30, 2023 compared to the three months ended September 30, 2022 driven primarily by higher interest rates and a shift to higher-yielding assets. The average yield on earnings assets was 4.46% for the three months ended September 30, 2023, an increase of 72 basis points from the comparable quarter of the prior year. Interest expense increased by $1.6 million for the three months ended September 30, 2023 compared to the three months ended September 30, 2022 driven primarily by an increase in cost and amount of short-term and long-term borrowings to fund loan growth and deposit outflows. The average rate paid on interest bearing deposits was 0.26% for the three months ended September 30, 2023, an increase of 12 basis points from the comparable quarter of the prior year. The average rate paid on total borrowings was 3.83% for the three months ended September 30, 2023, an increase of 218 basis points from the comparable quarter last year.

Provision for Credit Losses and Unfunded Commitments
Based on the forward-looking metrics utilized within the CECL model, combined with the current market environment applied to the Bank’s loan portfolio, the provision for credit losses for the three months ended September 30, 2023 was $250 thousand, and the provision for unfunded commitments was a reversal of $171 thousand compared to no provision for the comparable quarter of the prior year. The determination of the provisions was a result of the analysis of the adequacy of the allowances for credit losses and unfunded commitments calculations. Each quarter, the Corporation assesses risks and reserves required compared with the balances in the allowance for credit losses and unfunded commitments.
Other Income
Total other income was $6.3 million for the three months ended September 30, 2023, an increase of $448 thousand, or 7.7%, from the comparable quarter of the prior year. The higher income was driven primarily by an increase of $200 thousand in commissions from insurance sales due to organic growth. In addition, income from fiduciary, investment management and brokerage activities increased $130 thousand, or 15.8%, driven primarily by strong market returns, an increase in estate settlement income and new business generation. Earnings on investment in bank-owned life insurance increased by $111 thousand due to additional purchases of insurance with a cash surrender value of $12.2 million during the second half of 2022. The net loss on equity securities for the three months ended September 30, 2023, improved to a $27 thousand net loss as compared to an $88 thousand net loss during the comparable quarter of the prior year. Other income in the three months ended September 30, 2023, increased $48 thousand, or 13.3%, to $410 thousand primarily driven by increases in third-party fee income and increases in letter of credit income.
Other Expenses
Other expenses for the quarter ended September 30, 2023 were $16.3 million an increase of $1.0 million, or 6.6%, from the comparable quarter of the prior year. Salaries and employee benefits increased by $749 thousand, or 8.0%, from the comparable quarter of the prior year, primarily driven by a general increase in base wages and commissions and an increase to accrued incentive compensation. Other operating increased $193 thousand, or 12.8%, driven primarily by an increase of $111 thousand in holding company related costs and $97 thousand in director-related fees partially offset by various miscellaneous expenses. Marketing and corporate relations expenses were $159 thousand for the third quarter of 2023 compared to $57 thousand for the comparable quarter of last year. The increase was driven by $73 thousand in expenses related to the rebranding of ACNB Bank’s Maryland banking divisions. FDIC and regulatory increased $125 thousand during the quarter ended September 30, 2023 compared to the same quarter of the prior year due to the timing of expense recognition.
Provision for Income Taxes
The Corporation recognized income taxes of $2.6 million during the third quarter of 2023 compared to $2.7 million income, during the comparable quarter in 2022. The provision for income taxes for the third quarter of 2023 reflects an effective combined Federal and state tax rate (ETR) of 22.2% compared to an ETR of 20.9% for the comparable period of 2022. Any variances from the federal statutory rate of 21% are generally due to tax-free income, which includes interest income on tax-free loans and investment securities and income from life insurance policies, federal income tax credits, and the impact of non-tax deductible expense. Low-income housing tax credits were $3 thousand and $70 thousand for the three months ended September 30, 2023 and 2022, respectively.
Nine Months ended September 30, 2023, compared to Nine Months ended September 30, 2022
Executive Summary
Net income for the nine months ended September 30, 2023, was $27.6 million compared to $25.6 million for the comparable period in 2022, an increase of $2.0 million, or 8.0%. Basic and diluted earnings per share for the nine month period in 2023 was $3.24 and $3.23, respectively, and $2.95 for both basic and diluted earnings per share for the comparable period of last year. The higher net income for the nine months ended September 30, 2023 was driven primarily by increases in net interest income and other income partially offset by an increase in total other expenses.
Net Interest Income
Net interest income totaled $66.8 million for the nine months ended September 30, 2023 compared to $59.4 million for the comparable period of last year, an increase of $7.5 million, or 12.5%. The increase in net interest income was primarily a result
31

of growth in higher-yielding interest earning assets coupled with higher interest rates. The FTE net interest margin for the first nine months of 2023 was 4.11%, a 96 basis points increase from 3.15% for the comparable period of last year. Year-to-date, PPP fees and purchase accounting accretion totaled $832 thousand compared to $2.8 million for the comparable period of the prior year. PPP fees were $8 thousand for the nine months ended September 30, 2023 compared to $1.3 million for the comparable period of the prior year.
Average earning assets declined year-over-year driven primarily by cash balances decreasing attributed to anticipated deposit outflows as market rates increased in 2022 and 2023. Given ACNB’s funding level, Management continued to restrain deposit rates despite an increase in market interest rates and an increase in rates by competitors. As a result, average deposits declined year-over-year as customers continued to seek higher yielding alternative deposit and investment products. However, interest income increased by $9.2 million for the nine months ended September 30, 2023 compared to the comparable period of last year driven by higher interest rates and a shift into higher yielding assets. The average yield on earnings assets increased to 4.39% for the nine months ended September 30, 2023 compared to 3.29% for the comparable period of the prior year, an increase of 110 basis points. Interest expense increased by $1.8 million for the nine months ended September 30, 2023 compared to the comparable period of the prior year driven by an increase in short-term and long-term borrowings. The average rate paid on interest-bearing deposits was 0.17% for the nine months ended September 30, 2023, an increase of 2 basis points as compared to 0.15% for the comparable period of last year. The average rate paid on total borrowings was 3.33% for the nine months ended September 30, 2023, an increase of 161 basis points from the comparable period last year.
Provision for Credit Losses and Unfunded Commitments
Based on the forward-looking metrics utilized within the CECL model, combined with the current market environment applied to the Bank’s loan portfolio, the provision for credit losses for the first nine months of 2023 was $74 thousand, and the provision for unfunded commitments was $226 thousand compared to no provision for the comparable period of the prior year. The determination of the provisions was a result of the analysis of the adequacy of the allowances for credit losses and unfunded commitments calculations. Each quarter, the Corporation assesses risks and reserves required compared with the balances in the allowance for credit losses and unfunded commitments.
Other Income
Total other income was $17.5 million for the nine months ended September 30, 2023, an increase of $1.1 million, or 6.7%, from the first nine months of 2022. At the Corporation’s wholly-owned insurance subsidiary, ACNB Insurance Services, Inc., commissions from insurance sales increased $934 thousand, or 14.5%, to $7.4 million during the period primarily due to the acquisition of the business and assets of the Hockley & O’Donnell Agency in the first quarter of 2022 and higher contingent income. Earnings on bank-owned life insurance increased by $347 thousand, or 33.0%, driven primarily by additional purchases of insurance with a cash surrender value of $12.2 million during the second half of 2022. Income from fiduciary, investment management and brokerage activities totaled $2.8 million for the nine months ended September 30, 2023, as compared to $2.4 million for the first nine months of 2022, a $323 thousand, or 13.2%, increase driven primarily by strong market returns and new business generation. A $22 thousand net loss on equity securities was recognized during the first nine months of 2023 compared to a $345 thousand net loss during the first nine months of 2022. A net loss of $739 thousand was recognized on the sales of securities during the first nine months of 2023, compared to no securities sold during the first nine months of 2022. Income from mortgage loans held for sale decreased by $437 thousand, or 93.4%, due to less mortgage activity as a result of an increase in the current rate environment and the strategic decision to retain more mortgage production.
Other Expenses
Other expenses for the nine months ended September 30, 2023 were $48.9 million an increase of $5.3 million, or 12.1%, from the first nine months of 2022. The increase was driven primarily by increases in salaries and employee benefits, other operating, professional services, marketing and corporate relations and equipment expenses. Salaries and employee benefits increased $4.1 million, or 15.8%, when comparing the first nine months of 2023 to the comparable period of the prior year. The increase in salaries and employee benefits expense was driven primarily by a $750 thousand partial reversal of incentive compensation in the first quarter of 2022, higher incentive compensation accrual for 2023 of $277 thousand, a reversal of $484 thousand of net deferred loan expense in the first quarter of 2022 as well as an increase in stock-based compensation expense of $539 thousand, an increase in pension expense of $470 thousand, an increase in the Bank’s salary continuation plan expense of $317 thousand and a general increase in base wages due to merit increases and the acquisition of Hockley & O’Donnell Agency in the first quarter of 2022. Other operating increased $679 thousand, or 15.3%, driven primarily by a loss of $142 thousand as a result of writing off an investment in a title agency, a $131 thousand of increased loan-related and general purpose insurance costs, an increase in costs for the Bank’s internet banking activity costs of $109 thousand, an increase of $118 thousand in director-related fees, and a mark-to-market loss of $66 thousand related to an SBIC fund. Professional services expense totaled $1.6
32

million during the first nine months of 2023 compared to $1.3 million for the comparable period of the prior year, an increase of $272 thousand or 20.5%. The increase in professional expenses was a result of additional expenses related to the transition of the Corporation’s independent audit firm, higher expenses for third-party consulting services for various projects within the organization, higher expenses for employee recruiting and increased legal fees. Marketing and corporate relations expenses were $472 thousand for the first nine months of 2023 compared to $227 thousand for the comparable period of last year. The increase was driven by $248 thousand expenses related to the rebranding of ACNB Bank’s Maryland banking divisions. Equipment expense increased by $218 thousand, or 4.8%, driven primarily by increases in third-party vendor software costs related to the Bank’s new loan origination system that was implemented in late 2022. FDIC and regulatory costs increased $134 thousand, or 16.8%, due to the timing of expense recognition.
Provision for Income Taxes
The Corporation recognized income taxes of $7.5 million, during the first nine months of 2023, compared to $6.6 million during the comparable period of 2022. The provision for income taxes for the first nine months of 2023 reflects an effective combined ETR of 21.4% compared to an ETR of 20.5% for the comparable period of 2022. Any variances from the federal statutory rate of 21% in the respective periods are generally due to tax-free income, which includes interest income on tax-free loans and investment securities and income from life insurance policies, federal income tax credits, and the impact of non-tax deductible expense. Low-income housing tax credits were $11 thousand and $211 thousand for the nine months ended September 30, 2023 and 2022, respectively.
FINANCIAL CONDITION
Assets totaled $2.4 billion at September 30, 2023 compared to $2.5 billion at December 31, 2022. The decrease from December 31, 2022 was driven primarily by a reduction in cash and cash equivalents to fund loan growth and deposit outflows driven by customers continuing to seek higher yielding alternative deposit and investment products as market interest rates rose during 2022 and 2023 and a reduction in available for sale securities due to general balance sheet and interest rate risk management. Total loans outstanding were $1.6 billion at September 30, 2023 compared to $1.5 billion at December 31, 2022. Loans increased by $77.4 million, or 5.0%, from December 31, 2022 to September 30, 2023, primarily from strong organic loan growth in 2023. Total securities were $501.1 million at September 30, 2023 compared to $620.3 million at December 31, 2022, a decrease of 19.2%. Total deposits were $2.0 billion at September 30, 2023. Deposits decreased by $247.6 million, or 11.3%, since December 31, 2022. Total borrowings were $153.4 million at September 30, 2023. Total borrowings increased by $90.4 million or 143.7%, since December 31, 2022 to fund deposit outflows and loan growth.
Investment Securities
ACNB uses investment securities to generate interest and dividend income, manage interest rate risk, provide collateral for certain funding products, and provide liquidity. The investment portfolio is comprised of U.S. Government and agency, mortgage-backed, state and municipal, and corporate securities. These securities provide the appropriate characteristics with respect to credit quality, yield and maturity relative to the management of the overall balance sheet.
At September 30, 2023, the securities balance included a net unrealized loss on available for sale securities of $59.7 million, net of taxes, on amortized cost of $510.8 million versus a net unrealized loss of $52.7 million, net of taxes, on amortized cost of $617.6 million at December 31, 2022. The change in fair value of available for sale securities was a result of an increase in market interest rates in 2022 and 2023. The changes in value are deemed to be related solely to changes in market interest rates as the credit quality of the portfolio remained strong.
At September 30, 2023, the securities balance included held to maturity securities with an amortized cost of $64.6 million and a fair value of $53.8 million as compared to an amortized cost of $65.0 million and a fair value of $58.1 million at December 31, 2022. These balances include unamortized, unrealized losses of $3.0 million and $3.9 million as of each respective period end which resulted from the transfer of approximately $39.7 million securities from available for sale to held to maturity during the second quarter of 2022.
The Corporation does not own investments consisting of pools of Alt-A or subprime mortgages, private label mortgage-backed securities, or trust preferred investments.
The fair values of securities available for sale (carried at fair value) are determined by obtaining quoted market prices on nationally recognized securities exchanges (Level 1) or by 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 security but
33

rather by relying on the security’s relationship to other benchmark quoted prices. The Corporation uses independent service providers to provide matrix pricing. Please refer to Note 7 — “Securities” in the Notes to Consolidated Financial Statements for more information on the security portfolio and Note 9 — “Fair Value Measurements” in the Notes to Consolidated Financial Statements for more information about fair value.
Loans
Loans outstanding increased by $77.4 million, or 5.0%, from December 31, 2022 to September 30, 2023. The increase in loans is largely attributable to growth in the commercial lending portfolio. Total commercial loans increased $51.9 million, or 4.8%, as compared to December 31, 2022. Commercial loans are spread among diverse categories that include municipal governments/school districts, commercial real estate, commercial real estate construction, and commercial and industrial. Residential real estate mortgage lending increased by $22.2 million, or 6.1%, as compared to December 31, 2022.
Most of the Corporation’s lending activities are with customers located within the Bank’s market area of southcentral Pennsylvania and northern Maryland. Non-owner occupied commercial real estate represented 60.4% of the commercial real estate portfolio. These borrowers are geographically dispersed throughout ACNB’s marketplace and are leasing commercial properties to a varied group of tenants including medical offices, retail space, and other commercial purpose facilities. Because of the varied nature of the tenants, in aggregate, management believes that these loans present an acceptable risk when compared to commercial loans in general. ACNB does not originate or hold Alt-A or subprime mortgages in its loan portfolio. For more information please see Note 8 — “Loans and Allowance for Credit Losses” in the Notes to Consolidated Financial Statements.
Allowance for Credit Losses and Asset Quality
The allowance for credit losses at September 30, 2023, was $19.3 million, or 1.19% of total loans as compared to $17.9 million, or 1.16% of loans, at December 31, 2022. As of January 1, 2023, upon adoption of ASU 2016-13, the allowance for credit losses was $19.5 million, or 1.27% of total loans. The increase from year-end was primarily driven by the adoption of CECL as shown in the table below. For more information please see Note 8 — “Loans and Allowance for Credit Losses” in the Notes to Consolidated Financial Statements.
Changes in the allowance for credit losses were as follows:

All nonaccrual loans are to borrowers located within the market area served by the Corporation in southcentral Pennsylvania and northern Maryland. All nonaccrual individually evaluated loans were originated by ACNB’s banking subsidiary.
Premises and Equipment
On January 12, 2022, ACNB Bank announced plans to build a full-service community banking office to serve the Upper Adams area of Adams County, PA. The Upper Adams Office opened in October 2022 and, as a result, three community banking offices were consolidated into the new community banking office. Two of the former community banking offices were subsequently transferred to Assets Held for Sale at fair market value. Also, as part of the Bank’s branch optimization program, in the third quarter of 2022, the Bank announced the planned closure of three additional community banking offices effective December 2022. As a result, two of the former community banking offices were transferred to Assets Held for Sale at fair market value. During the nine months ended September 30, 2023, the Bank sold four community banking offices for a net gain on sale of $337 thousand which was recorded as a gain on assets held for sale.
Foreclosed Assets Held for Resale
The carrying value of real estate acquired through foreclosure was $467 thousand which was comprised of one property at September 30, 2023. This same property was recorded in foreclosed assets held for resale as of December 31, 2022. All acquired properties are actively marketed.
Deposits
ACNB relies on deposits as a primary source of funds for lending activities with total deposits of $2.0 billion as of September 30, 2023. Deposits decreased by $247.6 million, or 11.3%, from December 31, 2022, to September 30, 2023. The decrease in deposits were in both non-interest bearing and interest bearing deposits, as a result of customers seeking higher yielding alternative investment or deposit products as market interest rates rose during 2022 and 2023 and management’s continued strategy of discipline deposit rate structure. Historically, deposits vary between quarters mostly reflecting different levels held by local companies, government units and school districts during different times of the year. Despite the decline in deposits in 2023, the loan-to-deposit ratio was 82.81% at September 30, 2023.
ACNB’s deposit pricing function employs a disciplined pricing approach based upon liquidity needs and alternative funding rates, but also strives to price deposits to be competitive with relevant local competition, including local government investment trusts, credit unions and larger regional banks. Given the Corporation’s funding level, the Corporation continued to restrain deposit rates despite an increase in market interest rates and increases in rates by competitors. Interest bearing deposit costs for
35

the third quarter of 2023 were 0.26% compared to 0.14% for the third quarter of 2022. The ratio of uninsured and non-collateralized deposits to total deposits was approximately 17.4% at September 30, 2023.
Borrowings
Short-term borrowings are comprised primarily of securities sold under agreements to repurchase and short-term borrowings from the FHLB. As of September 30, 2023, short-term Bank borrowings were $33.1 million, as compared to $42.0 million at December 31, 2022. Securities sold under repurchase agreements are within the commercial and local government customer base and have attributes similar to core deposits. Investment securities are pledged in sufficient amounts to collateralize these agreements. Compared to year-end 2022, securities sold under repurchase agreements balances decreased by $8.8 million, or 21.1%, due to changes in the cash flow position of ACNB’s commercial and local government customer base and competition from non-bank sources. There were no short-term FHLB borrowings at September 30, 2023 and December 31, 2022. Short-term FHLB borrowings are used to even out Bank funding from seasonal and daily fluctuations in the deposit base.
Long-term borrowings consist of longer-term advances from the FHLB, trust preferred subordinated debt and subordinated debt. Long-term borrowings totaled $120.3 million at September 30, 2023, versus $21.0 million at December 31, 2022. During 2023, the bank borrowed $100.0 million from the FHLB at a weighted average fixed rate of 4.63% for a weighted average term of 3.88 years to fund deposit outflows and loan growth. Further borrowings will be used when necessary for a variety of risk management and funding purposes. Please refer to the Liquidity discussion below for more information on the Corporation’s ability to borrow.
Capital
ACNB’s capital management strategies have been developed to provide an appropriate rate of return, in the opinion of management, to shareholders, while maintaining its “well-capitalized” regulatory position in relationship to its risk exposure. Please refer to the Risk-Based Capital section below for more information on the Corporation’s capital ratio.
The primary source of additional capital to ACNB is earnings retention, which represents net income less dividends declared. During the first nine months of 2023, ACNB earned $27.6 million and paid dividends of $7.2 million for a dividend payout ratio of 25.94%. Comparatively, during the first nine months of 2022, ACNB earned $25.6 million and paid dividends of $6.7 million for a dividend payout ratio of 26.35%.
On October 24, 2022, the Corporation announced that the Board of Directors approved on October 18, 2022, a new plan to repurchase, in open market and privately negotiated transactions, up to 255,575, or approximately 3%, of the outstanding shares of the Corporation’s common stock. This new common stock repurchase program replaces and supersedes any and all earlier announced repurchase plans. As of September 30, 2023, 47,228 shares of common stock have been repurchased under this new plan.
ACNB Corporation has a Dividend Reinvestment and Stock Purchase Plan that provides registered holders of ACNB Corporation common stock with a convenient way to purchase additional shares of common stock by permitting participants in the plan to automatically reinvest cash dividends on all or a portion of the shares owned and to make quarterly voluntary cash payments under the terms of the plan. Participation in the plan is voluntary, and there are eligibility requirements to participate in the plan. During the nine months ended September 30, 2023, 16,580 shares were issued under this plan with proceeds in the amount of $543 thousand and during the nine months September 30, 2022, 16,226 shares were issued under this plan with proceeds in the amount of $535 thousand.
On March 30, 2021, the Corporation issued $15.0 million of subordinated debt in order to pay off existing higher rate debt, to potentially repurchase ACNB common stock and to use for inorganic growth opportunities. Otherwise, the $15.0 million of subordinated debt qualifies as Tier 2 capital at the Holding Company level, but can be transferred to the Bank where it qualifies as Tier 1 Capital. The debt has a 4.00% fixed-to-floating rate and a stated maturity of March 31, 2031. The debt is redeemable by the Corporation at its option, in whole or in part, on or after March 30, 2026, and at any time upon occurrences of certain unlikely events such as receivership, insolvency, or liquidation of ACNB or ACNB Bank.
The Corporation has trust preferred subordinated debt that was assumed by ACNB Corporation through the acquisition of Frederick County Bancorp, Inc. (FCBI). FCBI completed the private placement of an aggregate of $6.0 million of trust preferred securities. The interest rate on the trust preferred subordinated debt is adjusted quarterly to 163 basis points over the three-month Chicago Mercantile Exchange (CME) Term Secured Overnight Financing Rate (SOFR) plus applicable tenor spread adjustment. On September 15, 2023 the most recent interest rate reset date, the interest rate was adjusted to 7.30% for the period ending December 14, 2023. The trust preferred securities mature on December 15, 2036, and may be redeemed at
36

par, at the Corporation’s option, on any interest payment date. The trust preferred subordinated debt qualifies as Tier 1 capital.
ACNB is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on ACNB. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, ACNB must meet specific capital guidelines that involve quantitative measures of its assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and reclassifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Management believes, as of September 30, 2023, and December 31, 2022, that ACNB’s banking subsidiary met all minimum capital adequacy requirements to which it is subject and is categorized as “well capitalized” for regulatory purposes. There are no subsequent conditions or events that management believes have changed the banking subsidiary’s category.
Regulatory Capital
In July 2013, the federal banking agencies issued final rules to implement the Basel III regulatory capital reforms and changes required by the Dodd-Frank Act. The phase-in period for community banking organizations began January 1, 2015, while larger institutions (generally those with assets of $250 billion or more) began compliance effective January 1, 2014. The final rules call for the following capital requirements:
•a minimum ratio of common Tier 1 capital to risk-weighted assets of 4.50%;
•a minimum ratio of Tier 1 capital to risk-weighted assets of 6.00%;
•a minimum ratio of total capital to risk-weighted assets of 8.00%; and,
•a minimum leverage ratio of 4.00%.
In addition, the final rules established a common equity Tier 1 capital conservation buffer of 2.50% of risk-weighted assets applicable to all banking organizations.
Risk-Based Capital
In December 2018, the FDIC approved a final rule to address changes to credit loss accounting under GAAP, including banking organizations’ implementation of CECL. The final rule provides banking organizations the option to phase in over a three-year period the day-one adverse effects on regulatory capital that may result from the adoption of the new accounting standard. The Corporation adopted CECL effective January 1, 2023 and elected to implement the capital transition relief over the permissible three-year period.
In 2019, the federal banking agencies issued a final rule to provide an optional simplified measure of capital adequacy for qualifying community banking organizations, including the community bank leverage ratio (CBLR) framework. Generally, under the CBLR framework, qualifying community banking organizations with total assets of less than $10.0 billion, and limited amounts of off-balance sheet exposures and trading assets and liabilities, may elect whether to be subject to the CBLR framework if they have a CBLR of greater than 9.00% (subsequently reduced to 8.00% as a COVID-19 relief measure). Qualifying community banking organizations that elect to be subject to the CBLR framework and continue to meet all requirements under the framework would not be subject to risk-based or other leverage capital requirements and, in the case of an insured depository institution, would be considered to have met the well capitalized ratio requirements for purposes of the FDIC’s Prompt Corrective Action framework. The CBLR framework was available for banks to use in their March 31, 2020 Call Report. The Corporation has performed changes to capital adequacy and reporting requirements within the quarterly Call Report, and it opted out of the CBLR framework.

Liquidity
Effective liquidity management ensures the cash flow requirements of depositors and borrowers as well as the operating cash needs of ACNB are met. ACNB’s funds are available from a variety of sources, including assets that are readily convertible such as interest bearing deposits wit h banks, maturities and repayments from the securities portfolio, scheduled repayments of loans receivable, the core deposit bas e, the ability to raise brokered deposits, and the ability to borrow from, including but not limited to, the FHLB, Federal Reserve Discount Window and other contingent sources.
ACNB manages liquidity by monitoring projected cash inflows and outflows on a daily basis, and believes it has sufficient funding sources to maintain sufficient liquidity under varying degrees of business conditions for liquidity and capital resource requirements for all material short- and long-term cash requirements from known contractual and other obligations.
At September 30, 2023, ACNB’s banking subsidiary could borrow approximately $845.5 million from the FHLB, of which $745.2 million was available. At September 30, 2023, ACNB’s banking subsidiary could borrow approximately $3.6 million from the Discount Window, of which the full amount was available. The underlying collateral at the Discount Window is made up of investment securities held in a joint-custody account under the Bank’s name.
1 Ratios do not include capital conservation buffer.
38

A new Federal Reserve lending facility, named the Bank Term Funding Program, was enacted in March 2023 that provides banks the ability to borrow on the par value of certain investment securities used to collateralize the account. As of September 30, 2023, ACNB’s banking subsidiary could borrow approximately $169.0 million from the Bank Term Funding Program, of which the full amount was available.
ACNB’s banking subsidiary maintains several unsecured Fed Funds lines with correspondent banks. As of September 30, 2023, Fed Funds line capacity at the banking subsidiary was $132.0 million, of which the full amount was available. In 2018, ACNB Corporation executed a guaranty for a note related to a $1.5 million commercial line of credit from a local bank, with normal terms and conditions for such a line, for ACNB Insurance Services, Inc., the borrower and a wholly-owned subsidiary of ACNB Corporation. The commercial line of credit is for general working capital needs as they arise and did not have any outstanding balance as of September 30, 2023. ACNB Corporation maintains a $5.0 million unsecured line of credit with a correspondent bank. The line of credit remains at full capacity as of September 30, 2023.
Another source of liquidity is securities sold under repurchase agreements to customers of ACNB’s banking subsidiary totaling approximately $33.1 million and $42.0 million at September 30, 2023, and December 31, 2022, respectively. These agreements vary in balance according to the cash flow needs of customers and competing accounts at other financial organizations.
The liquidity of the parent company also represents an important aspect of liquidity management. The parent company’s cash outflows consist principally of dividends to shareholders and corporate expenses. The main source of funding for the parent company is the dividends it receives from its subsidiaries. Federal and state banking regulations place certain legal restrictions and other practicable safety and soundness restrictions on dividends paid to the parent company from the subsidiary bank.
Off-Balance Sheet Arrangements
The Corporation is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and, to a lesser extent, standby letters of credit. At September 30, 2023, the Corporation had unfunded outstanding commitments to extend credit of $423.4 million and outstanding standby letters of credit of $22.8 million. Because these commitments generally have fixed expiration dates and many will expire without being drawn upon, the total commitment level does not necessarily represent future cash requirements.
Market Risks
During March and April 2023 three significant bank failures occurred (Silicon Valley Bank, Signature Bank and First Republic Bank). This was and continues to be accompanied by financial instability at certain additional banks. These bank failures and bank instabilities have created and may continue to create market and other risks, for all financial institutions and banks, including ACNB. These risks include, but are not limited to:
•market risk and loss of confidence in the financial services sector, and/or specific banks;
•deterioration of securities and loan portfolios;
•deposit volatility and/or reductions with higher volumes and occurring over shorter periods of time;
•increased liquidity demand and utilization of sources of liquidity; and,
•interest rate volatility and abrupt, sudden and greater than usual rate changes.
These factors individually, or in any combination, could materially and adversely affect:
•financial condition;
•operations and results thereof; and,
•stock price.
In addition, the previously mentioned bank failures and instabilities may result in an increase of FDIC deposit insurance premiums and/or result in special FDIC deposit insurance assessments, which may adversely affect the Corporation’s financial
39

condition, operations, results thereof or stock price.
The Corporation cannot predict the impact, timing or duration of such events.
Financial institutions can be exposed to several market risks that may impact the value or future earnings capacity of the organization. These risks involve interest rate risk, foreign currency exchange risk, commodity price risk, and equity market price risk. ACNB’s primary market risk is interest rate risk. Interest rate risk is inherent because, as a financial institution, ACNB derives a significant amount of its operating revenue from “purchasing” funds (customer deposits and wholesale borrowings) at various terms and rates. These funds are then invested into earning assets (primarily loans and investments) at various terms and rates.
RECENT LEGAL AND REGULATORY DEVELOPMENTS
Management has reviewed the recent development sections that were previously disclosed in the Annual Report on Form 10-K for the fiscal period ended December 31, 2022. There are no material changes in the recent legal and regulatory development section as previously disclosed in the recent developments section on the Form 10-K.
SUPERVISION AND REGULATION
Dividends
ACNB is a legal entity separate and distinct from its subsidiary bank. ACNB’s revenues, on a parent company only basis, result primarily from dividends paid to the Corporation by its subsidiaries. Federal and state laws regulate the payment of dividends by ACNB’s subsidiary bank and state laws effect dividends by ACNB’s insurance subsidiary. For further information, please refer to Regulation of Bank below.
Regulation of Bank
The operations of the subsidiary bank are subject to statutes applicable to banks chartered under the banking laws of Pennsylvania, to state nonmember banks of the Federal Reserve, and to banks whose deposits are insured by the FDIC. The subsidiary bank’s operations are also subject to regulations of the Pennsylvania Department of Banking and Securities, Federal Reserve, and FDIC.
The Pennsylvania Department of Banking and Securities, which has primary supervisory authority over banks chartered in Pennsylvania, regularly examines banks in such areas as reserves, loans, investments, management practices, and other aspects of operations. The subsidiary bank is also subject to examination by the FDIC for safety and soundness, as well as consumer compliance. These examinations are designed for the protection of the subsidiary bank’s depositors rather than ACNB’s shareholders. The subsidiary bank must file quarterly and annual reports to the Federal Financial Institutions Examination Council, or FFIEC.
Monetary and Fiscal Policy
ACNB and its subsidiary bank are affected by the monetary and fiscal policies of government agencies, including the Federal Reserve and FDIC. Through open market securities transactions and changes in its discount rate and reserve requirements, the Board of Governors of the Federal Reserve exerts considerable influence over the cost and availability of funds for lending and investment. The nature and impact of monetary and fiscal policies on future business and earnings of ACNB cannot be predicted at this time. From time to time, various federal and state legislation is proposed that could result in additional regulation of, and restrictions on, the business of ACNB and the subsidiary bank, or otherwise change the business environment. Management cannot predict whether any of this legislation will have a material effect on the business of ACNB.
ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Management monitors and evaluates changes in market conditions on a regular basis. Based upon the most recent review, management has determined that there have been no material changes in market risks since year-end 2022. For further discussion of year-end information, please refer to the Annual Report on Form 10-K for the fiscal year ended December 31, 2022.

ITEM 4 – CONTROLS AND PROCEDURES
EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES
As of the end of the period covered by this report, the Corporation carried out an evaluation, under the supervision and with the participation of its management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of its disclosure controls and procedures pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Corporation’s disclosure controls and procedures are effective in timely alerting them to material information relating to the Corporation (including its consolidated subsidiaries) required to be included in periodic SEC filings.
Disclosure controls and procedures are Corporation controls and other procedures that are designed to ensure that information required to be disclosed by the Corporation in the reports that it files or submits under the Securities Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
There were no changes in the Corporation’s internal control over financial reporting during the quarter ended September 30, 2023, that have materially affected, or are reasonably likely to materially affect, the internal control over financial reporting.

PART II – OTHER INFORMATION
ACNB CORPORATION
ITEM 1 – LEGAL PROCEEDINGS
As of September 30, 2023, there were no material pending legal proceedings, other than ordinary routine litigation incidental to the business, to which ACNB or its subsidiaries are a party or by which any of their assets are the subject, which could have a material adverse effect on ACNB or its subsidiaries or their results of operations. In addition, no material proceedings are pending or are known to be threatened or contemplated against the Corporation or its subsidiaries by governmental authorities.
ITEM 1A – RISK FACTORS
Management has reviewed the risk factors that were previously disclosed in the Annual Report on Form 10-K for the fiscal year ended December 31, 2022. There are no material changes in risk factors as previously disclosed in the Form 10-K except as described below.
CALENDAR YEAR 2023 NEGATIVE DEVELOPMENTS AFFECTING THE BANKING INDUSTRY, INCLUDING BANK FAILURES OR CONCERNS REGARDING LIQUIDITY, HAVE ERODED CUSTOMER CONFIDENCE IN THE BANKING SYSTEM AND MAY HAVE A MATERIAL ADVERSE EFFECT ON THE CORPORATION.
During 2023 events impacting the banking industry, including the high-profile failures or instability of certain banking institutions, have resulted in general uncertainty and eroded confidence in the safety, soundness, and financial strength of the financial services sector. In particular, the bank failures highlighted the potential serious impact of a financial institution unable to meet withdrawal requests by depositors. This has resulted in a growing concern about liquidity in the banking industry, access to and volatile capital markets and reduced stock valuations for certain financial institutions. Similar future events, including additional bank failures or bank instability, could directly or indirectly adversely impact the Corporation’s own liquidity, access to capital markets, stock price, financial condition and results of operations. Further, these recent events may also result in: greater regulatory scrutiny and enforcement; additional and more stringent laws and regulations for the financial services industry; increased FDIC deposit insurance premiums or special FDIC assessments; and higher capital ratio requirements, which as a result could have a material negative impact and adverse effect on the Corporation’s business, financial condition and results of operations.
ITEM 2 – UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
On May 5, 2009, shareholders approved and adopted the amendment to the Articles of Incorporation of ACNB Corporation to authorize up to 20,000,000 shares of preferred stock, par value $2.50 per share. As of September 30, 2023, there were no issued or outstanding shares of preferred stock.
On May 1, 2018, shareholders approved and ratified the ACNB Corporation 2018 Omnibus Stock Incentive Plan, effective as of March 20, 2018, in which awards shall not exceed, in the aggregate, 400,000 shares of common stock, plus any shares that were authorized, but not issued, under the ACNB Corporation 2009 Restricted Stock Plan. The ACNB Corporation 2009 Restricted Stock Plan expired by its own terms after 10 years on February 24, 2019. No further shares may be issued under this plan and the remaining 174,055 shares were transferred to the ACNB Corporation 2018 Omnibus Stock Incentive Plan. As of September 30, 2023, there were 100,746 shares issued under this plan. The maximum number of shares that may yet be granted under this plan is 473,309. The Corporation’s Registration Statement under the Securities Act of 1933 on Form S-8 for the ACNB Corporation 2018 Omnibus Stock Incentive Plan was filed with the Securities and Exchange Commission on March 8, 2019. In addition, on March 8, 2019, the Corporation filed Post-Effective Amendment No. 1 to the Registration Statement on Form S-8 for the ACNB Corporation 2009 Restricted Stock Plan to add the ACNB Corporation 2018 Omnibus Stock Incentive Plan to the registration statement.
On October 24, 2022, the Corporation announced that the Board of Directors approved on October 18, 2022, a new plan to repurchase, in open market and privately negotiated transactions, up to 255,575, or approximately 3%, of the outstanding shares of the Corporation’s common stock. This new common stock repurchase program replaces and supersedes any and all earlier announced repurchase plans. During the quarter ended September 30, 2023, 46,378 shares of common stock had been repurchased under this new plan.
