NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) N OTE 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 June 30, 2026, 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, 2025, 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 June 30, 2026 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 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. In November 2025, the FASB issued ASU 2025-08, Financial Instruments – Credit Losses (Topic 326) , which amends the guidance in Topic 326 to expand the population of acquired financial assets subject to the gross-up approach to include loans (excluding credit cards) that are acquired without credit deterioration and deemed “seasoned.” All non-purchased credit deteriorated loans (excluding credit cards) that are acquired in a business combination are deemed seasoned. Other non-purchased credit deteriorated loans (excluding credit cards) are considered to be seasoned if they were purchased at least 90 days after origination and the acquirer was not involved in the origination of the loans. ASU 2025-08 should be applied prospectively and is effective for annual reporting periods beginning after December 15, 2026, including interim reporting periods within those annual reporting periods. Early adoption is permitted. This Update is not expected to have an impact on the Company’s financial statements. 8 CSB BANCORP, INC.

Restricted stock primarily consists of investments in Federal Home Loan Bank of Cincinnati (FHLB) and Federal Reserve Bank stock. The Bank’s investment in FHLB stock amounted to approximately $ 1.1 million on June 30, 2026 and December 31, 2025 . Federal Reserve Bank stock was $ 471 thousand on June 30, 2026 and December 31, 2025. There were no proceeds from sales of securities for the six-month periods ended June 30, 2026 and 2025. All gains and losses recognized on equity securities during the six-month periods were unrealized. 10 CSB BANCORP, INC.

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 $ 96 million of total AFS securities. The remaining $ 25 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 $ 7 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. 11 CSB BANCORP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Note 2 – SECURITIES (continued) 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 June 30, 2026 , 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.

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. 13 CSB BANCORP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 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 $ 131 million and $ 132 million on June 30, 2026 and December 31, 2025, 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 surrounding counties. The majority of the Company’s loan portfolio consists of commercial and commercial real estate loans. Credit evaluation is based on a review of cash flow coverage of principal, interest payments, and the adequacy of the collateral received. The top five collateral exposures in commercial real estate and commercial lessors of buildings at June 30, 2026 are as follows: Industrial, manufacturing and production $ 82 million; healthcare facilities $ 47 million; warehouses $ 38 million; residential investment property $ 36 million; and animal feed production $ 25 million. Allowance for Credit Losses The following table details activity in the allowance for credit losses ("ACL") by portfolio segment for the three and six months ended June 30, 2026 and 2025 . 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 and six months ended June 30, 2026, the increase in the ACL relates to one individually evaluated loan relationship reported in prior periods that is collateral dependent through its continued operation, corresponding increases in loan volume, and additional provision for credit losses for home equity lines of credit due to forecasted economic conditions affecting the consumer. For the three and six months ended June 30, 2025, the increase in the provision for credit losses on commercial real estate loans primarily relates to the increase in loan volume, as well as a charge-off of $ 301 thousand recognized during the second quarter. The increase in provision for commercial and industrial loans for the six month period primarily relates to loan growth and an increase in nonperforming commercial credit cards during the first quarter of 2025, which has improved in the second quarter and contributed to the second quarter provision decrease in this category. The increase in provision amounts for the remaining loan categories primarily relates to changes in loan volume. 14 CSB BANCORP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 3 – LOANS (CONTINUED) 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. 18 CSB BANCORP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 3 – LOANS (CONTINUED) Loans not meeting the criteria above that are analyzed individually as part of the above-described process are considered to be pass rated loans.

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 June 30, 2026 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 experiencing financial difficulty 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. 22 CSB BANCORP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 3 – LOANS (CONTINUED) There was one modification of a loan to a borrower experiencing financial difficulty completed during the six month period ended June 30, 2026 and no modifications of loans to borrowers experiencing financial difficulty during the six month period June 30, 2025.

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. 24 CSB BANCORP, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 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 June 30, 2026 and December 31, 2025 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.

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. 25 CSB BANCORP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 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 June 30, 2026 and December 31, 2025 , related to commitments to extend credit and letters of credit. The aggregate contract amount of such financial instruments was approximately $ 288 million on June 30, 2026 and $ 294 million on December 31, 2025. 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. 27 CSB BANCORP, INC.

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 June 30, 2026 as compared to December 31, 2025, and the consolidated results of operations for the three and six months ended June 30, 2026 compared to the same periods in 2025. 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. FORWARD-LOOKING STATEMENTS Certain statements contained in this Quarterly Report are not historical facts but rather are forward-looking statements that are subject to certain risks and uncertainties. When used herein, the terms “anticipates”, “plans”, “expects”, “believes”, and similar expressions as they relate to the Company or its management are intended to identify forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

FINANCIAL CONDITION Total assets remain steady at $1.29 billion at June 30, 2026 and December 31, 2025. During the six months ended June 30, 2026, securities decreased $20 million, net loans increased $39 million, and cash and cash equivalents decreased $18 million. Deposits and short-term borrowings decreased $4 million. Net loans increased $39 million, or 5%, as commercial and commercial real estate loans increased $21 million, or 4%, compared to December 31, 2025 and residential real estate loans increased $5 million, or 2%, from December 31, 2025. Construction loans increased $8 million, or 17%, from December 31, 2025. Consumer refinance activity remains slow on mortgage loans, while home construction activity rose as well as home equity line origination increases of $21 million. Residential mortgage loan originations, including home equity lines, for the six months ended June 30, 2026 totaled $40 million, an increase from $32 million in mortgage originations during the six months ended June 30, 2025. Mortgage loan originations sold into the secondary market remained stable at $4 million, during the six months ended June 30, 2026 and June 30, 2025 respectively. The Bank originates and sells primarily fixed rate thirty-year mortgages into the secondary market. The allowance for credit losses for loans increased $1 million from December 31, 2025 to $13.5 million. The increase in the allowance was due to one individually evaluated loan relationship, an increase in loan volume, and an increase in risk forecast within the home equity line portfolio. Net charge-offs were $35 thousand, or an annualized 0.01% of average loans, in the current six-month period compared to net charge-offs of $391 thousand, or 0.10% of average loans in the year-ago six-month period. At June 30, 2026, the allowance for credit losses to total loans was 1.56%. 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. 29 CSB BANCORP, INC. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Nonperforming loans increased $6.6 million to $7.3 million, or 0.84%, of total loans from $652 thousand, or 0.08% of total loans, on December 31, 2025. For the six months ended June 30, 2026, $6.7 million in loans were placed on nonaccrual status, $93 thousand in paydowns were received, and no nonperforming loans were charged-off due to non-payment. June 30, December 31, June 30, (Dollars in thousands) 2026 2025 2025 Non-performing loans $ 7,287 $ 652 $ 1,357 Allowance for credit losses 13,528 12,470 8,251 Total loans 869,348 829,778 788,070 Allowance for credit losses as a percentage of total loans 1.56 % 1.50 % 1.05 % Allowance for credit losses to total nonperforming loans 1.9 X 19.1 X 6.1 X The ratio of gross loans to deposits was 77% and 74% at June 30, 2026 and December 31, 2025. 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 $29 million within the available-for-sale and held-to-maturity portfolios as of June 30, 2026, 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 June 30, 2026, are considered temporary and no allowance for credit loss is necessary. The weighted average life of total debt securities was 5.10 years at June 30, 2026 as compared to 5.12 years at December 31, 2025. If interest rates declined 100 basis points, the weighted average life was estimated to fall to 4.57 years at June 30, 2026. If interest rates rose 100 basis points the weighted average life would be expected to increase to 5.57 years at June 30, 2026. Deposits increased $5 million, or 0.5%, from December 31, 2025 with noninterest-bearing deposits decreasing approximately $1.8 million, or 0.6%, and interest-bearing deposit accounts increasing approximately $7 million, or 0.9%. Total deposits as of June 30, 2026 are $1.1 billion, or 4%, above June 30, 2025 deposit balances. On a year over year comparison, increases were recognized in interest bearing demand accounts of $11 million, time deposits of $27 million noninterest-bearing demand deposits of $4 million, and savings accounts of $3 million. Decreases were recognized in money market accounts of $378 thousand. 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, $281 million, and $266 million as of June 30, 2026, December 31, 2025, and June 30, 2025, respectively. Short-term borrowings consisting of overnight repurchase agreements with retail customers decreased $10 million, or 30%, to $22 million at June 30, 2026 as compared to December 31, 2025. These balances have returned to a more typical amount and are even with June 30, 2025. Other borrowings decreased $223 thousand as the Company repaid FHLB advances. Total shareholders’ equity amounted to $133 million, or 10%, of total assets at June 30, 2026, an increase of $6.3 million, or 5%, from $126 million at December 31, 2025. The increase in shareholders’ equity during the six months ended June 30, 2026 was due to net income of $9.2 million, net of other comprehensive loss of $570 thousand and cash dividends of $2.3 million. Total accumulated other comprehensive loss ("AOCL") increased during the six months ended June 30, 2026 due to higher U.S. Treasury rates and decreased prices 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 June 30, 2026 as shown in the Capital Resources section of this report. RESULTS OF OPERATIONS Three months ended June 30, 2026 and 2025 For the quarters ended June 30, 2026 and 2025, the Company recorded net income of $4.7 million and $3.7 million and $1.80 and $1.41 per share, respectively. The $1 million increase in net income for the period 30 CSB BANCORP, INC. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS was primarily the result of an increase of $1.5 million in net interest income, a $175 thousand increase in non interest income, and a decrease in the provision for credit losses and off-balance sheet commitments of $29 thousand. The noninterest expense increase of $465 thousand partially offset the revenue increases. The federal income tax provision increased $262 thousand.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Interest income for the quarter ended June 30, 2026, was $15 million representing a $1.5 million, or 11% increase, compared to the same period in 2025. This increase was primarily due to the higher average balances of loans of $83 million. These increases were partially offset by volume decreases in securities and interest-earning deposits in other banks of $18 million over the comparable period. Rates on average interest-earning deposits in other banks decreased 76 basis points, while loan rates increased 13 basis points, and securities' interest rates increased 32 basis points for the quarter ended June 30, 2026 as compared to the same period in 2025. Interest expense for the quarter ended June 30, 2026 was $3.5 million, a decrease of $35 thousand, or 1%, from the same quarter in 2025. The decrease in interest expense occurred primarily due to rate decreases in time deposit accounts during the quarter ended June 30, 2026. For the quarter ended June 30, 2026, the bank recognized net charge-offs of $28 thousand, compared to $362 thousand net charge-offs for the same quarter in 2025. The provision for credit losses on loans in the current quarter of $609 thousand, compared to a provision of $639 thousand in the same quarter ended 2025. The Company recorded a $24 thousand recovery for credit loss expense on off-balance commitments in the second quarter 2026 compared to a $25 thousand recovery in the same quarter of 2025. 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 $175 thousand, or 10%, compared to the second quarter of 2025. The increase was primarily the result of a $49 thousand increase in debit card interchange fees, a $42 thousand increase in credit card fees, $37 thousand increase in earnings on bank owned life insurance, $28 thousand increase in service charges on deposits. Noninterest expense increased $465 thousand, or 7%, from the second quarter 2025. Salary and employee benefit costs increased $328 thousand, or 8%, compared to the prior year quarter with an increase in the number of full time equivalent employees from 175 in 2025 to 185 in 2026 as vacant positions were filled. Software expense increased $83 thousand, or 19%, debit card expense increased $23 thousand or 12%. Occupancy expense decreased $16 thousand, or 5%. The Company’s second quarter efficiency ratio decreased to 53.1% compared to 56.6% in the prior year. Federal income tax expense increased $262 thousand, or 29%, for the quarter ended June 30, 2026 as compared to the second quarter 2025. The provision for income taxes was $1.2 million (effective rate of 19.8%) for the quarter ended June 30, 2026, compared to $903 thousand (effective rate of 19.5%) for the same quarter ended 2025. RESULTS OF OPERATIONS Six months ended June 30, 2026, and 2025 For the six months ended June 30, 2026, and 2025, the Company recorded net income of $9.2 million and $7.3 million and $3.49 and $2.78 per share, respectively. The $2 million increase in net income for the six-month period was primarily the result of $3 million increase to net interest income. The increase to net income was partially offset by an increase in noninterest expense of $1 million. The federal income tax provision was $477 thousand higher during the six-month period in 2026 than in 2025. Return on average assets and return on average equity were 1.45% and 14.26%, respectively, for the six months ended June 30, 2026, compared to 1.22% and 12.53%, respectively for the same period in 2025. 32 CSB BANCORP, INC.

Interest income for the six months ended June 30, 2026, was $30 million representing a $3 million increase, or 12%, compared to the same period in 2025. This increase was primarily due to volume and yield increases on loans for the period ended June 30, 2026, as compared to the same period in 2025. Interest expense for the six months ended June 30, 2026, was $7 million, a decrease of $130 thousand, or 2%, from the same period in 2025. For the six months ended June 30, 2026, the provision for credit losses and off-balance sheet commitments was $1 million stable with 2025. For more discussion see Results of Operations, three months. 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 for the six months ended June 30, 2026, was $3.8 million, an increase of $351 thousand, or 10%, compared to the same period in 2025. Credit card fees increased $83 thousand, debit card interchange fee increased $77 thousand, and earnings on bank owned life insurance policies increased $76 thousand for the period. Trust services increased $61 thousand or 11%. 33 CSB BANCORP, INC. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Noninterest expenses for the six months ended June 30, 2026, increased $1.3 million, or 10%, compared to the same period in 2025. Salaries and employee benefits increased $864 thousand, or 11%, a result of increases in base salaries and benefits, partially due to increased headcount as the company was able to reduce vacancies and add several new positions supporting growth . Software expense increased $201 thousand, or 24%, primarily due to new loan production software. The provision for income taxes was $2.3 million (effective rate of 19.7%) for the six months ended June 30, 2026, compared to $1.8 million (effective rate of 19.5%) for the same period ended 2025. CAPITAL RESOURCES The Company maintained a strong capital position with tangible common equity to tangible assets (a non-GAAP measure) of 9.9% at June 30, 2026 compared with 9.4% at December 31, 2025. 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%. 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, 2025. As of June 30, 2026, the Company and the Bank met all capital adequacy requirements to which they were subject.

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. 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 Six Months Ended June 30, June 30, (Dollars in thousands, except per share data) 2026 2025 2026 2025 Net income $ 4,735 $ 3,727 $ 9,179 $ 7,343 Weighted average common shares outstanding 2,627,015 2,639,244 2,627,015 2,641,879 Earnings per share, basic and diluted $ 1.80 $ 1.41 $ 3.49 $ 2.78 35 CSB BANCORP, INC. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK ITEM 3 - QUANTITATIVE AND QUALITAT IVE DISCLOSURES ABOUT MARKET RISK The most significant market risk the Company is exposed to is interest rate risk. The business of the Company and the composition of its balance sheet consist of investments in interest-earning assets (primarily loans and securities), which are funded by interest-bearing liabilities (deposits and borrowings). These financial instruments have varying levels of sensitivity to changes in the market rates of interest, resulting in market risk. None of the Company’s financial instruments are held for trading purposes. The Board of Directors establishes policies and operating limits with respect to interest rate risk. The Company manages interest rate risk regularly through its Asset Liability Committee. The Committee meets periodically to review various asset and liability management information including, but not limited to, the Company’s liquidity position, projected sources and uses of funds, interest rate risk position, and economic conditions. Interest rate risk is monitored primarily through the use of an earnings simulation model. The model is highly dependent on various assumptions, which change regularly as the balance sheet and market interest rates change. The earnings simulation model projects change in net interest income resulting from the effect of changes in interest rates. The analysis is performed quarterly over a twenty-four-month horizon. The analysis includes two (2) balance sheet models, one based on a static balance sheet and one on a dynamic balance sheet with projected growth in assets and liabilities. This analysis is performed by estimating the expected cash flows of the Company’s financial instruments using interest rates in effect at June 30, 2026 and December 31, 2025. Interest rate risk policy limits are tested by measuring the anticipated change in net interest income over a two-year period. The tests assume quarterly ramped increases and decreases in market interest rates over twenty-four month horizons, as compared to a stable rate environment or base model. The following table reflects the change to net interest income using a dynamic balance sheet for the first twelve-month periods of the twenty-four month horizon.
