NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accompanying condensed consolidated financial statements include the accounts of CSB Bancorp, Inc. and its wholly-owned subsidiaries, The Commercial and Savings Bank (the “Bank”) and CSB Investment Services, LLC (together referred to as the “Company” or “CSB”). All significant intercompany transactions and balances have been eliminated in consolidation.

The condensed consolidated financial statements have been prepared without audit. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present fairly the Company’s financial position at September 30, 2025, and the results of operations and changes in cash flows for the periods presented have been made.

Certain information and footnote disclosures typically included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been omitted. The Annual Report for CSB for the year ended December 31, 2024, contains Consolidated Financial Statements and related footnote disclosures, which should be read in conjunction with the accompanying condensed Consolidated Financial Statements. The results of operations for the period ended September 30, 2025 are not necessarily indicative of the operating results for the full year or any future interim period.

Certain items in the prior-year financial statements were reclassified to conform to the current-year presentation. Such reclassifications had no effect on net income or shareholders’ equity.

USE OF ESTIMATES IN PREPARING FINANCIAL STATEMENTS

In preparing the Consolidated Financial Statements, in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the Consolidated Balance Sheets and reported amounts of revenues and expenses during each reporting period. Actual results could differ from those estimates. The most significant estimates susceptible to change in the near term relate to management’s determination of the allowance for credit losses and the fair value of financial instruments.

RECENTLY ISSUED ACCOUNTING PRONOUNCMENTS

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which provides for improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. This guidance is effective for public business entities for annual periods beginning after December 15, 2024, and for annual periods beginning after December 15, 2025, for all other entities. The Company adopted the new disclosures for the annual periods beginning on January 1, 2025. The Company will include the applicable and relevant required disclosures in the Income Taxes footnote in the Form 10-K for the year ending December 31, 2025.

In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures. This ASU requires disclosure in the notes to financial statements of specified information about certain costs and expenses. Specific disclosures are required for (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil and gas producing activities. The amendments in this Update do not change or remove current expense disclosure requirements. However, the amendments affect where this information appears in the notes to financial statements because entities are required to include certain current disclosures in the same tabular format disclosure as the other disaggregation requirements in the amendments. The amendments in ASU 2024-03 apply only to public business entities and are effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact of this new guidance on its financial statements.

There were 98 securities in an unrealized loss position on September 30, 2025, 94 of which were in a continuous loss position for twelve (12) months or more. Each quarter the Company conducts a comprehensive security-level impairment assessment on the securities portfolio. Management believes the Company will fully recover the cost of these securities. Unrealized losses on the Company’s fixed-rate debt securities are a result of interest rate increases. U.S. Treasury securities and investments in securities of U.S. government sponsored agency bonds comprise $73 million of total AFS securities. The remaining $37 million of non-agency debt securities is made up of Corporate Bonds and debt securities to State and Political Subdivisions. For non-agency debt securities, the Company verified the current credit ratings remain above investment grade. Non-rated debt securities total $10 million. Annually, management reviews the credit profile of each non-rated issue and assesses whether any impairment to the contractually obligated cash flow is likely to occur. Based on these reviews, management has concluded the underlying creditworthiness for each security remains sufficient to maintain required payment obligations and, therefore, no allowance for credit losses has been recorded. Management believes the value will recover as the securities approach maturity or market interest rates change.

The Bank monitors the credit quality of held-to-maturity debt securities primarily through utilizing their credit rating. The Bank monitors the credit rating on a quarterly basis. There are no nonperforming held-to-maturity securities. As of September 30, 2025, no ACL was required for any held-to-maturity security. The majority of the securities are explicitly or implicitly guaranteed by the United States government, and any estimate of expected credit losses would be insignificant to the Bank. The following table summarizes the amortized cost of held-to maturity debt securities at September 30, 2025 and December 31, 2024, aggregated by credit quality indicator:

Loan Origination/Risk Management

The Company has certain lending policies and procedures in place that are designed to maximize loan income within an acceptable level of risk. Management reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management with frequent reports related to loan production, loan quality, concentrations of credit, loan delinquencies and non-performing and potential problem loans. Diversification in the loan portfolio is a means of managing risk associated with fluctuations in economic conditions.

Commercial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. Underwriting standards are designed to promote relationship banking rather than transactional banking. The Company’s management examines current and occasionally projected cash flows to determine the ability of the borrower to repay their obligations as agreed. Commercial loans are primarily made based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers; however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable, inventory, and equipment, and may incorporate a personal guarantee; however, some short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers.

Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans, in addition to those of real estate loans. These loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. The properties securing the Company’s commercial real estate portfolio are diverse in terms of type. This diversity helps reduce the Company’s exposure to adverse economic events that affect any single industry. Management monitors and evaluates commercial real estate loans based on collateral, geography, and risk grade criteria. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner occupied.

The top ten collateral exposures in commercial real estate and commercial lessors of buildings at September 30, 2025 are as follows: Industrial, manufacturing and production $73 million; warehouse $41 million: healthcare facilities $39 million; residential investment property $31 million; animal feed production $20 million; auto repair $19 million; hotels $19 million; retail strip center $19 million; retail stores $17 million; senior housing $12 million.

NOTE 3 – LOANS (CONTINUED)

With respect to loans to developers and builders that are secured by non-owner-occupied properties, the Company generally requires the borrower to have had an existing relationship with the Company and have a proven record of success. Construction and land development loans are underwritten utilizing independent appraisal reviews, sensitivity analysis of absorption and lease rates, and financial analysis of the developers and property owners. These loans are generally based upon estimates of costs and values associated with the completed project. These estimates may be inaccurate.

Construction and land development loans often involve the disbursement of substantial funds with repayment dependent on the success of the project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of the developed property, or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risk than other real estate loans due to their repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions, and the availability of long-term financing.

The Company originates consumer loans utilizing a judgmental underwriting process. To monitor and manage consumer loan risk, policies and procedures are developed and modified, as needed. This activity, coupled with relatively small loan amounts that are spread across many individual borrowers, mitigates risk.

The Company maintains an independent credit department that reviews and validates the credit risk program on a periodic basis. Results of these reviews are presented to management. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Company’s policies and procedures.

Loans serviced for others approximated $133 million and $136 million on September 30, 2025 and December 31, 2024, respectively.

Concentrations of Credit

Nearly all the Company’s lending activity occurs within the state of Ohio, including the five counties of Holmes, Medina, Stark, Tuscarawas, and Wayne, as well as other markets. The majority of the Company’s loan portfolio consists of commercial and commercial real estate loans. Credit concentrations, including commitments, as determined using North American Industry Classification Codes (NAICS), to the three largest industries compared to total loans on September 30, 2025, included $85 million, or 10%, of total loans to lessors of non-residential buildings, $37 million, or 5%, of total loans to manufacturers of animal food, and $31 million, or 4%, of total loans to lessors of residential buildings. These loans are generally secured by real property and equipment, with repayment expected from operational cash flow. Credit evaluation is based on a review of cash flow coverage of principal, interest payments, and the adequacy of the collateral received.

Allowance for Credit Losses

The following table details activity in the allowance for credit losses ("ACL") by portfolio segment for the three and nine months ended September 30, 2025 and 2024. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

For the three months ended September 30, 2025, the increase in the provision for credit losses across all loan types was primarily related to the increase in loan volume as well as the average life extension of loans held in the portfolio. For the nine months ended September 30, 2025, the increase in provision for commercial real estate was also affected by charge-offs of $303 thousand during the period. The increase in provision amounts for the remaining loan categories primarily relates to changes in loan volume and average life extension.

NOTE 3 – LOANS (CONTINUED)

For the three and nine months ended September 30, 2024, the increase in the provision for commercial and industrial loans primarily relates to one individually evaluated commercial loan relationship which has been charged-down to the fair value of the collateral. The commercial and industrial charge-off amount related to this loan relationship was $3.9 million and the commercial real estate charge-off for this same relationship was $420 thousand. The charge-offs also increased the historical loss rates which are applied to the active balances multiplied by the weighted average life of the loan pools. The remaining provision amounts for the quarter are primarily a result of changes in loan volume and weighted average remaining maturities of the loans in each category.

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes commercial loans individually by classifying the loans as to credit risk. This analysis includes all commercial loans before origination and an annual review of those with an outstanding commitment greater than $500 thousand. The Company uses the following definitions for risk ratings:

Pass. Loans classified as pass (Cash Secured, Exceptional, Acceptable, Monitor, or Pass Watch) may exhibit a wide array of characteristics but at a minimum represent an acceptable risk to the Bank. Borrowers in this rating may have leveraged but acceptable balance sheet positions, satisfactory asset quality, stable to favorable sales and earnings trends, acceptable liquidity and adequate cash flow. Loans are considered fully collectible and require an average amount of administration. While generally adhering to credit policy, these loans may exhibit occasional exceptions that do not result in undue risk to the Bank. Borrowers are generally capable of absorbing setbacks, financial and otherwise, without the threat of failure.

Special Mention. Assets assigned a Special Mention grade are not considered classified assets but are considered criticized. These assets exhibit potential weaknesses that, deserve management’s close attention. If left uncorrected, those potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Bank’s credit position at some future date. Loans in this rating warrant special attention but have not yet reached the point of concern for loss. These assets have deteriorated sufficiently to the point they would have difficulty refinancing elsewhere. Similarly, purchasers of the business would not be eligible for bank financing unless they represent a significantly stronger credit risk.

Substandard. Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions, and values, highly questionable and improbable.

Consumer mortgages are substantially secured by one to four family owner occupied properties and consumer indirect loans are substantially secured by recreational vehicles. All nonperforming consumer loans are evaluated when placed on nonaccrual status and may be charged down based on the collateral fair value less cost to sell if that value is lower than the outstanding balance. As of September 30, 2025 there were no loans secured by consumer real estate in process of foreclosure.

Modifications to Borrowers Experiencing Financial Difficulty

Occasionally, the Bank modifies loans to borrowers in financial distress by providing – principal forgiveness, term extension, an other-than-insignificant payment delay or interest rate reduction. When principal forgiveness is provided, the amount of forgiveness is charged-off against the allowance for credit losses. In some cases, the Bank may provide multiple types of concessions on one loan. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted.

There were no modifications of loans to borrowers in financial distress completed during the three and nine months ended September 30, 2025 and 2024.

NOTE 5 – FAIR VALUE MEASUREMENTS

The Company provides disclosures about assets and liabilities carried at fair value. The framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and lowest priority to unobservable inputs. The three broad levels of the fair value hierarchy are described below:

Level I:	Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access.
Level II:	Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in inactive markets; inputs other than quoted prices that are observable for the asset or liability; and inputs that are derived principally from or corroborated by observable market data by corroborated or other means. If the asset or liability has a specified (contractual) term, the Level II input must be observable for substantially the full term of the asset or liability.
Level III:	Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

NOTE 5 – FAIR VALUE MEASUREMENTS (CONTINUED)

The following table presents the assets reported on the Consolidated Balance Sheets at their fair value on a recurring basis as of September 30, 2025 and December 31, 2024 by level within the fair value hierarchy. No liabilities are carried at fair value. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Equity securities with readily determinable values and U.S. Treasury Notes are valued at the closing price reported on the active market on which the individual securities or identical securities are traded. Obligations of U.S. government agencies, mortgage-backed securities, asset-backed securities, obligations of states and political subdivisions and corporate bonds are valued at observable market data for similar assets. Equity securities without readily determinable values are carried at amortized cost adjusted for impairment and observable price changes and are not included in the table below.

The following methods and assumptions were used by the Company in determining the fair value of assets measured at fair value on a nonrecurring basis as described below:

Individually evaluated collateral dependent loans: Loans that are collateral dependent are written down to fair value through the establishment of specific reserves. Techniques used to value the collateral securing these loans include: quoted market prices for identical assets classified as Level I inputs; observable inputs, employed by certified appraisers, for similar assets classified as Level II inputs. In cases where valuation techniques included unobservable inputs and are based on estimates and assumptions developed by management based on the best information available under each circumstance, the asset valuation is classified as Level III inputs.

NOTE 6 – FAIR VALUES OF FINANCIAL INSTRUMENTS (CONTINUED)

Other financial instruments carried at amortized cost include cash and cash equivalents, restricted stock, bank-owned life insurance, accrued interest receivable, short-term borrowings, and accrued interest payable, all of which have a Level I fair value that approximates their carrying value. The Company also has unrecognized financial instruments on September 30, 2025 and December 31, 2024, related to commitments to extend credit and letters of credit. The aggregate contract amount of such financial instruments was approximately $290 million on September 30, 2025 and $289 million on December 31, 2024.

The fair value estimates of financial instruments are made at a specific point in time based on relevant market information. Since no ready market exists for a significant portion of the financial instruments, fair value estimates are largely based on judgments after considering such factors as future expected credit losses, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore, cannot be determined with precision. Changes in assumptions could significantly affect these estimates.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

ITEM 2 - MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following management’s discussion and analysis focuses on the consolidated financial condition of the Company on September 30, 2025 as compared to December 31, 2024, and the consolidated results of operations for the three and nine months ended September 30, 2025 compared to the same periods in 2024. The purpose of this discussion is to provide the reader with a more thorough understanding of the Consolidated Financial Statements. This discussion should be read in conjunction with the interim condensed Consolidated Financial Statements and related footnotes contained in Part I, Item 1 of this Quarterly Report.

FINANCIAL CONDITION

Total assets increased $57 million to $1.25 billion at September 30, 2025 compared to $1.19 billion at December 31, 2024. During the nine months ended September 30, 2025, securities decreased $24 million, net loans increased $71 million, and cash and cash equivalents increased $7 million. Deposits and short-term borrowings increased $46 million.

Net loans increased $71 million, or 10%, as commercial and commercial real estate loans increased $71 million, or 16%, compared to December 31, 2024 and residential real estate loans increased $19 million, or 9%, from December 31, 2024. Construction loans decreased $16 million, or 26%, from December 31, 2024. Consumer refinance activity remains slow on mortgage loans, while home construction activity rose as well as home equity line origination increases of $5 million. Residential mortgage loan originations, including home equity lines, for the nine months ended September 30, 2025 totaled $56 million, an increase from $46 million in mortgage originations during the nine months ended September 30, 2024. Mortgage loan originations sold into the secondary market decreased slightly to $6 million from $7 million, respectively during the nine months ended September 30, 2025 and September 30, 2024. The Bank originates and sells primarily fixed rate thirty-year mortgages into the secondary market.

The allowance for credit losses for loans increased $1.1 million from December 31, 2024 to $8.7 million. The increase in the allowance was primarily due to the volume increase in loans originated. Net charge-offs were $402 thousand, or an annualized 0.07% of average loans, in the current nine-month period compared to net charge-offs of $4.3 million, or 0.81% of average loans in the year-ago nine-month period. At September 30, 2025, the allowance for credit losses to total loans was 1.08%. We believe the allowance level is appropriate given the level of problem loans and composition of the overall loan portfolio in the current economic environment.

CSB BANCORP, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Nonperforming loans decreased $959 thousand to $746 thousand, or 0.09%, of total loans from $1.7 million, or 0.23% of total loans, on December 31, 2024. For the nine months ended September 30, 2025, $451 thousand in loans were placed on nonaccrual status, $529 thousand in paydowns were received, and $394 thousand in loans were charged-off due to non-payment.

Non-performing loans	$	746		$	1,705		$	3,372

Allowance for credit losses as a percentage of total loans		1.08	%		1.03	%		1.00	%
Allowance for credit losses to total nonperforming loans		1,169	%		445	%		214	%

The ratio of gross loans to deposits was 74% and 71% at September 30, 2025 and December 31, 2024.

The Company has no exposure to government-sponsored enterprise preferred stocks, collateralized debt obligations, or trust preferred securities. Management has considered industry analyst reports, sector credit reports, and the volatility within the bond market in concluding that the gross unrealized losses of $30 million within the available-for-sale and held-to-maturity portfolios as of September 30, 2025, was primarily the result of current market yields compared to the yields at the time the investments were purchased by the Company and not due to credit quality. As a result, all embedded security losses on September 30, 2025, are considered temporary and no allowance for credit loss is necessary.

The weighted average life of total debt securities was 5.30 years at September 30, 2025 as compared to 5.14 years at December 31, 2024. If interest rates declined 100 basis points, the weighted average life was estimated to fall to 4.91 years at September 30, 2025. If interest rates rose 100 basis points the weighted average life would be expected to increase to 5.64 years at September 30, 2025.

Deposits increased $52 million, or 5%, from December 31, 2024 with noninterest-bearing deposits decreasing approximately $3 million, or 1%, and interest-bearing deposit accounts increasing approximately $55 million, or 7%. Total deposits as of September 30, 2025 are $1.1 billion, or 2%, above September 30, 2024 deposit balances. On a year over year comparison, increases were recognized in money market accounts of $7 million, savings accounts of $3 million, interest bearing demand accounts of $3 million, and time deposits of $22 million. Decreases were recognized in noninterest-bearing demand deposits of $7 million. Deposits have increased as customers move funds into interest bearing demand accounts and time certificates of deposit to take advantage of higher interest rates in those products. The estimated amount of uninsured deposits was $272 million, $244 million, and $275 million as of September 30, 2025, December 31, 2024, and September 30, 2024, respectively.

Short-term borrowings consisting of overnight repurchase agreements with retail customers decreased $5 million, or 21%, to $20 million at September 30, 2025 as compared to December 31, 2024 as customers moved money into higher interest rate money market and time deposit accounts. Other borrowings decreased $325 thousand as the Company repaid FHLB advances.

Total shareholders’ equity amounted to $125 million, or 10%, of total assets at September 30, 2025, an increase of $10.4 million, or 9%, from $115 million at December 31, 2024. The increase in shareholders’ equity during the nine months ended September 30, 2025 was due to net income of $11.5 million, other comprehensive income of $2.8 million, less cash dividends of $3.2 million, and treasury stock repurchases of $726 thousand. Total accumulated other comprehensive loss ("AOCL") decreased during the nine months ended September 30, 2025 due to decreases in interest rates and improvements in pricing in government agency and corporate bonds as AFS securities are marked to fair value. This remaining unrealized loss in securities is temporary and is adjusted monthly for additional interest rate fluctuations, principal paydowns, calls, and maturities. The Company and the Bank met all regulatory capital requirements at September 30, 2025 as shown in the Capital Resources section of this report.

RESULTS OF OPERATIONS

Three months ended September 30, 2025 and 2024

For the quarters ended September 30, 2025 and 2024, the Company recorded net income of $4.2 million and $3.1 million and $1.57 and $1.18 per share, respectively. The $1 million increase in net income for the period was primarily the result of an increase of $1.7 million in net interest income, a reduced provision for credit losses and off-balance sheet commitments of $501 thousand compared to the provision for credit losses in the prior year period of $700 thousand. Additionally, a $57 thousand increase in noninterest income was offset by a $711 thousand increase in noninterest expenses. The federal income tax provision increased $263 thousand. Pre-provision net revenue ("PPNR"), (a non-GAAP measure), totaled $5.7 million for the quarter ended September 30, 2025, an increase of $1.1 million, or 23%, from the prior year's third quarter.

Return on average assets and return on average equity were 1.31% and 13.19%, respectively, for the three-month period of 2025, compared to 1.05% and 11.14%, respectively for the same quarter in 2024.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Interest income for the quarter ended September 30, 2025, was $14.7 million representing a $1.5 million, or 12% increase, compared to the same period in 2024. This increase was primarily due to higher average balances of loans and interest-earning deposits in other banks. These increases were partially offset by the volume decreases in taxable securities over the comparable period. Rates on average interest-earning deposits in other banks decreased 98 basis points, while loan rates rose 19 basis points, and taxable securities' interest rates increased 15 basis points for the quarter ended September 30, 2025 as compared to the same period in 2024. Interest expense for the quarter ended September 30, 2025 was $3.8 million, a decrease of $200 thousand, or 5%, from the same quarter in 2024. The decrease in interest expense occurred primarily due to rate decreases in time deposit accounts during the quarter ended September 30, 2025.

For the quarter ended September 30, 2025, the bank recognized net charge-offs of $11 thousand, compared to $4 million net charge-offs for the same quarter in 2024. The provision for credit losses on loans in the current quarter of $480 thousand, compared to a provision of $645 thousand in the same quarter ended 2024. The company recorded a $21 thousand provision for credit loss expense on off-balance commitments in the third quarter 2025 compared to a $55 thousand provision in the same quarter of 2024. The quarter decrease results primarily from a decrease in construction loan commitments during third quarter 2025.

Economic indicators reflect somewhat flat business activity with uncertainty related to trade policies and rising Ohio unemployment rates. The provision for credit losses is determined based on management’s calculation of the adequacy of the allowance for credit losses, which includes provisions for classified loans as well as for the remainder of the portfolio based on historical data, including past charge-offs and current economic trends.

Noninterest income increased $57 thousand, or 3%, compared to the third quarter of 2024. The increase was primarily the result of a $28 thousand increase in debit card interchange fees, $26 thousand increase in earnings on bank owned life insurance, $20 thousand increase in credit card fees, and a $20 thousand increase in trust services. These increases were partially offset by a decrease of $41 thousand in gain on sale of loans and a $21 thousand increase in unrealized losses on equity securities.

Noninterest expense increased $711 thousand, or 11%, from the third quarter 2024. Salary and employee benefit costs increased $453 thousand, or 12%, compared to the prior year quarter with increases in base salary, retirement, and incentive compensation. Professional and director fees increased $111 thousand, or 28%, software expense increased $77 thousand, or 18%, state financial institutions tax increased $10 thousand, or 5%, due to the increase in capital. Equipment expense decreased $24 thousand, or 11%. The Company’s third quarter efficiency ratio decreased to 55.6% compared to 58.2% in the prior year.

Federal income tax expense increased $263 thousand, or 32%, for the quarter ended September 30, 2025 as compared to the third quarter 2024. The provision for income taxes was $1 million (effective rate of 19.7%) for the quarter ended September 30, 2025, compared to $756 thousand (effective rate of 19.4%) for the same quarter ended 2024.

RESULTS OF OPERATIONS

Nine months ended September 30, 2025, and 2024

For the nine months ended September 30, 2025, and 2024, the Company recorded net income of $11.5 million and $7.7 million and $4.35 and $2.89 per share, respectively. The $4 million increase in net income for the nine-month period was primarily the result of a $3.7 million increase to net interest income and the provision for credit losses and off-balance sheet commitments decreasing to $1.5 million compared to the provision for credit losses in the prior year period of $4.7 million. The increase to net income was partially offset by an increase in noninterest expense of $2 million.

The federal income tax provision was $1 million higher during the nine-month period in 2025 than in 2024 due to increased taxable income. Return on average assets and return on average equity were 1.26% and 12.76%, respectively, for the nine months ended September 30, 2025, compared to 0.88% and 9.30%, respectively for the same period in 2024.

CAPITAL RESOURCES

The Company maintained a strong capital position with tangible common equity to tangible assets of 9.7% at September 30, 2025 compared with 9.3% at December 31, 2024.

Consistent with the Board of Director’s commitment to public confidence and safe and sound banking operations, capital targets and minimum risk-based capital ratios for CSB were established to maintain excess capital to well-capitalized standards. To be considered well-capitalized, an institution must have a total risk-based capital ratio of at least 10%, a tier 1 capital ratio of at least 8%, a leverage capital ratio of at least 5%, a common equity tier 1 (“CET1”) ratio of at least 6.5% and must not be subject to any order or directive requiring the institution to improve its capital level. An adequately capitalized institution has a total risk-based capital ratio of at least 8%, a tier 1 capital ratio of at least 6%, a CET1 ratio of at least 4.5%, and a leverage ratio of at least 4%.

CSB BANCORP, INC.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Failure to meet specified minimum capital requirements could result in regulatory actions by the Federal Reserve or Ohio Division of Financial Institutions that could have a material effect on the Company’s financial condition or results of operations. Management believes there were no material changes to capital resources as presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. As of September 30, 2025, the Company and the Bank met all capital adequacy requirements to which they were subject.

Liquidity refers to the Company’s ability to generate sufficient cash to fund current loan demand, meet deposit withdrawals, pay operating expenses, and meet other obligations. Liquidity is monitored by the Company’s Asset Liability Committee. Other sources of liquidity include, but are not limited to, purchases of federal funds, advances from the FHLB, adjustments of interest rates to attract deposits, brokered deposits, and borrowing at the Federal Reserve discount window. Additionally, the Company could sell all of its AFS securities and the loss would not cause a change in the capital adequacy classification. Management believes its sources of liquidity are adequate to meet cash flow obligations for the foreseeable future.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Off-Balance Sheet Arrangements

The Company does not have any off-balance sheet arrangements (as such term is defined in applicable Securities and Exchange Commission (the “Commission”) rules) that are reasonably likely to have a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures, or capital resources.

PER SHARE DATA

Earnings per share is computed based on the weighted average number of shares of common stock outstanding during each year. The company currently maintains a simple capital structure, thus, there are no dilutive effects on earnings per share.

The weighted average number of common shares outstanding for earnings per share computations was as follows:

	Three Months Ended				Nine Months Ended
	September 30,				September 30,

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Ohio's unemployment rate continues to rise slightly to 5.0% in August 2025 which was up from 4.4% in December 2024. Holmes County, where the bank is headquartered, is reporting an unemployment rate of 3.5% in August 2025. Of the counties within the bank's footprint, Stark County reported the highest unemployment rate at 5.1%, while Tuscarawas, Wayne, and Medina Counties posted unemployment rates of 4.6%, 4.4% and 3.2% respectively in August 2025. The rate of inflation, as measured by the Consumer Price Index was 2.9% on a year over year basis in August 2025, following average inflation rates of 2.9% in 2024, 4.1% in 2023 and 8.0% in 2022. The rate continues to be above the Federal Reserve target rate of 2%. The Federal Reserve reduced the federal funds target rate in 2024 by 1.00% and through October 2025 there have been two rate reductions totaling 0.50%, bringing the federal funds target rate to a range of 3.75% to 4.00%.

Management performs a quarterly analysis of the Company’s interest rate risk over a twenty-four-month horizon. The analysis includes two balance sheet models, one based on a static balance sheet and one on a dynamic balance sheet with projected growth in assets and liabilities. All balance sheet positions, and interest rate projections are currently within the Company’s board-approved policy for both the twelve- month and twenty-four-month periods.

The following table presents an analysis of the estimated sensitivity of the Company’s annual net interest income to sudden and sustained -400 through +400 basis point changes, in 100 basis point increments, in market interest rates at September 30, 2025 and December 31, 2024. The net interest income reflected is for the first twelve-month period of the modeled twenty-four-month horizon. The underlying balance sheet for illustrative purposes is dynamic with projected growth in assets and liabilities.
