Notes to Interim Consolidated Financial Statements (Unaudited)

Form 10-Q

(Amounts in thousands, except share data)

(1) Cons olidated Financial Statements

Nature of Operations and Principles of Consolidation : Civista Bancshares, Inc. ("CBI") is an Ohio corporation and a registered financial holding company. The Consolidated Financial Statements include the accounts of CBI and its wholly-owned direct and indirect subsidiaries: Civista Bank ("Civista"), First Citizens Insurance Agency, Inc. ("FCIA"), Water Street Properties, Inc. ("WSP"), CIVB Risk Management, Inc. ("CRMI") and First Citizens Investments, Inc. ("FCI"). The above companies together are sometimes referred to as the "Company". Intercompany balances and transactions are eliminated in consolidation. Management considers the Company to operate primarily in one reportable segment, banking.

Civista provides financial services through its offices in the Ohio counties of Erie, Crawford, Champaign, Cuyahoga, Franklin, Logan, Summit, Huron, Ottawa, Madison, Montgomery, Henry, Wood, and Richland, in the Indiana counties of Dearborn and Ripley, and in the Kentucky county of Kenton. Its primary deposit products are checking, savings, and term certificate accounts, and its primary lending products are residential mortgage, commercial, and installment loans. Substantially all loans are secured by specific items of collateral including business assets, consumer assets and commercial and residential real estate. Commercial loans are expected to be repaid from cash flow from operations of businesses. There are no significant concentrations of loans to any one industry or customer. However, our customers’ ability to repay their loans is dependent on the real estate and general economic conditions in the area. Other financial instruments that potentially represent concentrations of credit risk include deposit accounts in other financial institutions.

Civista Leasing and Finance ("CLF"), formerly known as Vision Financial Group, Inc. ("VFG"), was acquired in the fourth quarter of 2022 as a wholly-owned subsidiary of Civista. As of August 31, 2023, VFG was merged into Civista and now operates as a full-service equipment leasing and financing division of Civista. The operations of CLF are headquartered in Pittsburgh, Pennsylvania.

FCIA is wholly-owned by CBI and was formed to allow CBI and its subsidiaries to participate in commission revenue generated through CBI's third-party insurance agreement. FCIA revenue was less than 1 % of total revenue for each of the quarters ended September 30, 2025 and 2024. WSP is wholly-owned by CBI and was formed to hold properties repossessed by CBI subsidiaries. WSP revenue was less than 1 % of total revenue for each of the quarters ended September 30, 2025 and 2024. CRMI is a captive insurance company that is wholly-owned by CBI and was formed in 2017 to provide property and casualty insurance coverage to CBI and its subsidiaries for which insurance may not be currently available or economically feasible in the insurance marketplace. CRMI revenue was less than 1 % of total revenue for each of the quarters ended September 30, 2025 and 2024. FCI is wholly-owned by Civista and holds and manages its securities portfolio. The operations of FCI are located in Wilmington, Delaware.

Agreement and Plan of Merger with The Farmers Savings Bank

On July 10, 2025, CBI and Civista entered into an Agreement and Plan of Merger (the “Merger Agreement”) with The Farmers Savings Bank, an Ohio-chartered bank headquartered in Spencer, Ohio (“Farmers”). Upon the terms and subject to the conditions of the Merger Agreement, at the effective time of the merger (the “Effective Time”), Farmers will merge with and into Civista, with Civista being the surviving bank in the merger (the “FSB Merger”). The acquisition of Farmers will add two branches in Medina and Lorain Counties in Northeast Ohio. As of September 30, 2025, Farmers reported total assets of $ 293 million, net loans of $ 106 million, and total deposits of $ 236 million.

Under the terms and subject to the conditions of the Merger Agreement, which has been unanimously approved by the Boards of Directors of both companies, CBI agreed to pay $ 34.925 million in cash and issue 1,434,491 common shares, in aggregate, for all of the outstanding Farmers shares, subject to potential adjustment based on Farmers’ equity prior to closing being $ 56.0 million. This implies an aggregate deal value of approximately $ 66.7 million based on the closing price of CBI’s common shares on October 24, 2025 of $ 22.18 .

Civista has received all required regulatory approvals for the FSB merger, which is expected to close in November 2025, pending approval by Farmer's shareholders and satisfaction of other customary closing conditions.

Offering of Common Shares

On July 10, 2025, CBI announced an underwritten public offering of up to a maximum of 3,788,238 of its common shares. CBI subsequently closed on the sale of 3,294,120 common shares on July 14, 2025, and the sale of an additional 494,118 common shares on July 16, 2025 pursuant to the underwriters’ exercise of their overallotment option, at the public offering price of $ 21.25 per share. The aggregate net proceeds from the Offering to CBI were approximately $ 75.7 million, after deducting $ 608 of direct expenses and the underwriting discount of $ 4.2 million. As of September 30, 2025, the net proceeds from the offering was used to pay-down short-term

(Amounts in thousands, except share data)

FHLB advances, but the long-term strategic plan is to use the net proceeds for general corporate purposes, which may include supporting organic growth opportunities and future strategic transactions.

The accompanying Unaudited Consolidated Financial Statements have been prepared by the Company without audit. In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the Company’s financial position as of September 30, 2025 and its results of operations and changes in cash flows for the periods ended September 30, 2025 and 2024 have been made. The results of operations for the three and nine months ended September 30, 2025 are not necessarily indicative of the operating results for the full year. Reference is made to the accounting policies of the Company described in the notes to the Audited Consolidated Financial Statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024 . The Company has consistently followed these policies in preparing this Quarterly Report on Form 10-Q, with the additions made to the accounting policy for derivatives to address derivatives designated as hedges, as described in Note 14.

(2) Significant Accounting Policies

Use of Estimates : To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. The allowance for credit losses, determination of goodwill impairment, and fair value measurements of financial instruments are considered material estimates that are particularly susceptible to significant change in the near term.

Revisions : The Company has voluntarily revised amounts reported in a previously issued financial statement to correct one immaterial error. Certain prior year amounts have been reclassified between non-interest income and non-interest expense for the first, second, and third quarters of 2024 to correct the presentation of certain intercompany amounts. The immaterial error was fully corrected as of the nine months ended September 30, 2025. These revisions had no impact to the Company's net income.

Recently Adopted and Newly Issued but Not Yet Effective Accounting Standards:

In November 2023, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this ASU apply to all public entities that are required to report segment information in accordance with FASB ASC Topic 280, Segment Reporting . The amendments in this ASU are intended to improve reportable segment disclosure requirements primarily through enhanced disclosures about significant segment expenses. The amendments require that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker ("CODM") and included within each reported measure of segment profit or loss. Public entities are required to disclose, on an annual and interim basis, an amount for other segment items by reportable segment and a description of its composition. In addition, public entities must provide all annual disclosures about a reportable segment’s profit or loss and assets currently required by FASB ASC Topic 280, Segment Reporting , in interim periods. The amendments clarify that if the CODM uses more than one measure of a segment’s profit or loss in assessing segment performance and deciding how to allocate resources, a public entity may report one or more of those additional measures of segment profit. However, at least one of the reported segment profit or loss measures (or the single reported measure, if only one is disclosed) should be the measure that is most consistent with the measurement principles used in measuring the corresponding amounts in the public entity’s consolidated financial statements. The amendments require that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Finally, the amendments require that a public entity that has a single reportable segment provide all the disclosures required by the amendments in the ASU and all existing segment disclosures in ASC Topic 280. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply the amendments retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The Company adopted ASU 2023-07 in 2024 with little impact as currently, the Company's financial service operations are considered by management to be aggregated in one reportable segment.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this ASU require that public business entities on an annual basis (a) disclose specific categories in the rate reconciliation and (b) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5% of the amount computed by multiplying pretax income or loss by the applicable statutory income tax rate). The amendments in this ASU also require that all entities disclose on an annual basis the amount of income taxes paid (net of refunds

received) disaggregated by federal (national), state, and foreign taxes, and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than 5% of total income taxes paid (net of refunds received). The amendments require that all entities disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. ASU 2023-09 is effective for public business entities for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments should be applied on a prospective basis. Retrospective application is permitted. The impact of ASU 2023-09 is not expected to be material to the Company's Consolidated Financial Statements.

In March 2024, the FASB issued ASU 2024-01, Compensation - Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards. The amendments clarify how an entity determines whether a profits interest or similar award is (i) within scope of Compensation - Stock Compensation (Topic 718) or (ii) not a share-based payment arrangement and therefore within the scope of other guidance. The amendments are effective for fiscal years beginning after December 15, 2024. The impact of ASU 2024-01 is not expected to be material to the Company's Consolidated Financial Statements.

In November 2024, the FASB issued ASU 2024-03: Income Statement-Reporting Comprehensive Income Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This ASU requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. This ASU does not change the expense captions an entity presents on the face its income statement. ASU 2024-03 can be applied prospectively, and it is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption and retrospective applications are permitted. The Company is currently evaluating the impact of ASU 2024-03 on its Consolidated Financial Statements.

In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810): Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity ("VIE"). The ASU revises the guidance in ASC 805 to clarify that, in determining the accounting acquirer in "a business combination that is effected primarily by exchanging equity interests in which a VIE is acquired," an entity would be required to consider the factors in ASC 805-10-55-12 through 55-15. Previously, the accounting acquirer in such transactions was always the primary beneficiary. The amendments in this ASU are effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal reporting periods. Early adoption is permitted as of the beginning of an interim or fiscal reporting period. The Company is currently evaluating the impact of ASU 2025-03, but it is not expected to have a material impact on its Consolidated Financial Statements.

At September 30, 2025, there were a tot al of 427 securities in t he portfolio with unrealized losses mainly due to higher current market rates when compared to the time of purchase. At December 31, 2024, the Company owned 508 securities that were in an unrealized loss position. The u nrealized losses on securities have not been recognized into income because the issuers’ securities are of high credit quality, management has the intent and ability to hold these securities for the foreseeable future, and the decline in fair value is largely due to currently higher market rates when compared to the time of purchase. The fair value is expected to recover as the securities approach their maturity date or reset date. The Company does not intend to sell until recovery and does not believe selling will be required before recovery.

Each quarter, we perform an analysis to determine if any of the unrealized losses on securities available-for-sale are comprised of credit losses as compared to unrealized losses due to market interest rate adjustments. Our assessment includes a review of the unrealized loss for each security issuance held; the financial condition and near-term prospects of the issuer, including external credit ratings and recent downgrades; and our ability and intent to hold the security for a period of time sufficient for a recovery in value. We also consider the extent to which the securities are issued by the federal government or its agencies, and any guarantee of issued amounts by those agencies. The portfolio continues to consist of a mix of fixed and floating-rate, high quality securities, largely rated AA (or better), displaying an overall effective duration of approximately 3.0 years. No credit losses were determined to be present as of September 30, 2025, as there was no credit quality deterioration noted. Therefore, no provision for credit losses on securities was recognized for the third quarter of 2025.

The following table presents the net gains and losses on equity investments recognized in earnings for the three and nine months ended September 30, 2025 and 2024, and the portion of unrealized gains and losses for the period that relates to equity investments held at September 30, 2025 and 2024:

Three Months Ended September 30, — 2025 2024 Nine Months Ended September 30, — 2025 2024
Net gains (losses) recognized on equity securities during the period $ 255 $ 223 $ 152 $ 156
Less: Net gains (losses) realized on the sale of equity securities during the period
Unrealized gains (losses) recognized on equity securities held at reporting date $ 255 $ 223 $ 152 $ 156

Equity securities consisting of investments in other financial institutions totaled $ 2.6 million as of September 30, 2025 and $ 2.4 million as of December 31, 2024.

Stock of the Federal Home Loan Bank of Chicago (“FHLBC”), the Federal Reserve Bank of Cleveland (“FRBC”), United Bankers' Bancorp, Farmer Mac and Norwalk Community Development Corp are included as Other securities on the Company's Consolidated Balance Sheets. FHLBC stock was recorded at $ 16.1 million at September 30, 2025 and $ 18.5 million at December 31, 2024. FRBC stock was recorded at $ 11.5 million at both September 30, 2025 and December 31, 2024. United Bankers' Bancorp stock was recorded at $ 225 at both September 30, 2025 and December 31, 2024. Farmer Mac stock was recorded at $ 42 at both September 30, 2025 and December 31, 2024. Norwalk Community Development Corp stock was recorded at $ 2 at both September 30, 2025 and December 31, 2024.

For the three and nine months ended September 30, 2025 , the Company provided $ 378 and $ 2,797 , respectively, to the allowance for credit losses, as compared to a provision of $ 1,346 and $ 5,188 , respectively, for the three and nine months ended September 30, 2024. The Company experienced an in crease in the allowance for credit losses year-to-date as required by our current expected credit loss ("CECL") model primarily due to loan growth. Lower provisions were primarily attributable to the slowdown in net loan growth as net loans grew $ 14.2 million for the nine months ended September 30, 2025, compared to $ 178.2 million for the same period in 2024, coupled with a decrease in specific reserves primarily related to one client that made a large paydown during the nine months ended September 30, 2025.

The Company’s internally assigned risk grades are as follows:

Pass – loans which are protected by the current net worth and paying capacity of the obligor or by the value of the underlying collateral.

Special Mention – loans where a potential weakness or risk exists, which could cause a more serious problem if not corrected.

Substandard – loans that have a well-defined weakness based on objective evidence and are characterized by the distinct possibility that Civista will sustain some loss if the deficiencies are not corrected.

Doubtful – loans classified as doubtful have all the weaknesses inherent in a substandard asset. In addition, these weaknesses make collection or liquidation in full highly questionable and improbable, based on existing circumstances.

Loss – loans classified as a loss are considered uncollectible, or of such value that continuance as an asset is not warranted.

Homogeneous loans, generally Residential Real Estate, Real Estate Construction, and Consumer and Other loans, are not risk-graded, except when collateral is used for a business purpose. These loans are monitored based on performance, with performing loans included as Pass and nonperforming loans included as Substandard.

Nonaccrual Loans: Loans are considered for nonaccrual status upon reaching 90 days delinquency, unless the loan is well secured and in the process of collection, although the Company may be receiving partial payments of interest and partial repayments of principal on such loans. When a loan is placed on nonaccrual status, previously accrued but unpaid interest is deducted from interest income. Payments received on nonaccrual loans are applied to the unpaid principal balance. A loan may be returned to accruing status only if one of two conditions are met: (1) the loan is well-secured and none of the principal and interest has been past due for a minimum of 90 days or (2) the principal and interest payments are reasonably assured and a sustained period of performance has occurred, generally six months.

Modifications to Borrowers Experiencing Financial Difficulty: The re was one loan modified to a borrower experiencing financial difficulty during the three months ended September 30, 2025 and two loans modified to a borrower experiencing financial difficulty during the nine months ended September 30, 2025. There were no loans modified during the three and nine months ended September 30, 2024. The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each loan upon loan origination or acquisition. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of loans to borrowers experiencing financial difficulty. The Company uses probability of default/loss given default, discounted cash flows or remaining life method to determine the allowance for credit losses. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification.

The following table shows the amortized cost basis at the end of the reporting period of the loans modified to borrowers experiencing financial difficulty, disaggregated by loan category and type of modification granted during the nine months ended September 30, 2025. The percentage of the amortized cost basis of loans that were modified to borrowers experiencing financial difficulty as compared to the amortized cost basis of each class of loan category is also presented below:

Upon the Company's determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount. The Company closely monitors the performance of the loans that were modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. There were no modification loans that had a payment default during the three and nine months ended September 30, 2025 and September 30, 2024, and were modified during the twelve months prior to that default to borrowers experiencing financial difficulty.

The following table presents the payment status of the loans that were modified to borrowers experiencing financial difficulties in the last twelve months ended September 30, 2025.

Individually Evaluated Loans: Larger ( greater than $350 ) Commercial & Agricultural and Commercial Real Estate loan relationships, as well as Residential Real Estate and Consumer loans and Lease Financing Receivables that are part of a larger relationship are individually evaluated on a quarterly basis, when they do not share similar risk characteristics with the collectively evaluated pools. These loans are analyzed to determine if it is probable that all amounts will not be collected according to the contractual terms of the loan agreement. If management determines that the value of the loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance estimate

or a charge-off to the allowance. The Company’s policy for recognizing interest income on individually evaluated loans does not differ from its overall policy for interest recognition.

Collateral-dependent loans consist primarily of Residential Real Estate, Commercial Real Estate and Commercial & Agricultural loans. Individually evaluated loans are collateral-dependent when foreclosure is probable or when the repayment of the loan is expected to be provided substantially through the operation or sale of the underlying collateral. When a loan is deemed collateral-dependent, the level of credit loss is measured by the difference between amortized cost of the loan and the fair value of collateral adjusted for estimated cost to sell. In the case of Commercial & Agricultural loans secured by equipment, the fair value of the collateral is estimated by third-party valuation experts. Loan balances are charged down to the underlying collateral value when they are deemed uncollectible. Note that the Company did not elect to use the collateral maintenance agreement practical expedient available under CECL.

Foreclosed Assets Held For Sale

Foreclosed assets acquired in settlement of loans are carried at fair value less estimated costs to sell and are included in Other assets on the Consolidated Balance Sheets. As of September 30, 2025 and December 31, 2024, the Company had initiated formal foreclosure procedures on $ 1,263 a nd $ 669 , respectively, of Residential Real Estate loans.

Allowance for Credit Losses on Off-Balance-Sheet Credit Exposures

The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk from a contractual obligation to extend credit, such as a loan commitment, credit line, letter of credit, or overdraft protection. The allowance for credit losses on off-balance-sheet credit exposures is adjusted as a provision for credit loss expense recognized within provision for credit losses on the Consolidated Statements of Operations. The estimated credit loss includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The estimate of expected credit loss is based on the historical loss rate for the loan class in which the loan commitments would be classified as if funded.

The following table lists the allowance for credit losses on off-balance sheet credit exposures as of the three and nine months ended September 30, 2025 and September 30, 2024:

(9) Earnings per Common Share

The Company has granted restricted stock awards with non-forfeitable rights (with respect to dividends), which are considered participating securities. Accordingly, earnings per common share are computed using the two-class method as required by ASC 260-10-45. Basic earnings per common share are computed as net income available to common shareholders divided by the weighted average number of common shares outstanding during the period, which excludes the participating securities. Diluted earnings per common share include the dilutive effect, if any, of additional potential common shares issuable under the Company’s equity incentive plan, computed using the treasury stock method. The Company had no dilutive securities for the three and nine months ended September 30, 2025 and September 30, 2024.

(10) Commitments, Contingencies and Off-Balance Sheet Risk

Some financial instruments, such as loan commitments, credit lines, letters of credit and overdraft protection, are issued to meet customers’ financing needs. These are agreements to provide credit or to support the credit of others, as long as the conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off-balance-sheet risk of credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of commitment. The contractual amounts of financial instruments with off-balance-sheet risk were as follows at September 30, 2025 and December 31, 2024:

Contract Amount — September 30, 2025 December 31, 2024
Fixed Rate Variable Rate Fixed Rate Variable Rate
Commitment to extend credit:
Lines of credit and construction loans $ 27,355 $ 665,675 $ 31,940 $ 657,401
Overdraft protection 10 45,138 10 55,085
Letters of credit 16 107 782 244
Total $ 27,381 $ 710,920 $ 32,732 $ 712,730

Commitments to make loans are generally made for a period of one year or less. Fixed rate loan commitments included in the table above had interest rates ranging from 3.10 % to 8.0 % at September 30, 2025 and from 3.1 % to 8.9 % at December 31, 2024 . Maturities extend up to 30 years.

Civista is required to maintain certain reserve balances on hand in accordance with the Federal Reserve Board requirements. No reserve balance was maintained, or required to be maintained, in accordance with such requirements at September 30, 2025 and December 31, 2024 .

(11) Pension Information

The Company sponsors a pension plan which is a noncontributory defined benefit retirement plan. Annual payments, subject to the maximum amount deductible for federal income tax purposes, are made to a pension trust fund. In 2006, the Company amended the pension plan to provide that no employee could be added as a participant to the pension plan after December 31, 2006. In 2014, the Company amended the pension plan again to provide that no additional benefits would accrue beyond April 30, 2014.

Net periodic pension cost was as follows:

Three Months Ended Nine Months Ended
September 30, September 30,
2025 2024 2025 2024
Service cost $ — $ — $ — $ —
Interest cost 96 95 288 286

The Company does no t expect to make any contribution to its pension plan in 2025 . The Company made no contribution to its pension plan in 2024 .

(12) Equity Incentive Plan

At the Company’s 2014 annual meeting, the shareholders adopted the Company’s 2014 Incentive Plan (“2014 Incentive Plan”). The 2014 Incentive Plan authorized the Company to grant options, stock awards, stock units and other awards for up to 375,000 common shares of the Company. The 2014 Incentive Plan expired in accordance with its terms on April 16, 2024 , and no further awards may be granted under the 2014 Incentive Plan after April 16, 2024. On February 20, 2024, the Company's Board of Directors adopted the Civista Bancshares, Inc. 2024 Incentive Plan (the "2024 Incentive Plan"), which was subsequently approved by the shareholders of the Company

Form 10-Q

(Amounts in thousands, except share data)

at the Annual Meeting of Shareholders held on April 16, 2024. The 2024 Incentive Plan authorizes the Company to grant options, stock awards, stock units and other awards for up to 450,000 common shares of the Company. There were 392,550 shares available for grants under the 2024 Incentive Plan at September 30, 2025.

No options were granted under the 2014 Incentive Plan or the 2024 Incentive Plan during the three and nine months ended September 30, 2025 and September 30, 2024.

In each of the past several years, the Board of Directors has awarded restricted common shares to senior officers of the Company. The restricted shares vest ratably over a three-year or five-year period following the grant date. The product of the number of restricted shares granted and the grant date market price of the Company’s common shares determines the fair value of restricted shares awarded under the Company’s incentive plans. Management recognizes compensation expense for the fair value of restricted shares on a straight-line basis over the requisite service period for the entire award.

The Company classifies share-based compensation for employees with “Compensation expense” in the Consolidated Statements of Operations.

The following is a summary of the Company’s outstanding restricted common shares and changes therein for the three and nine months ended September 30, 2025:

September 30, 2025 September 30, 2025
Number of Restricted Shares Weighted Average Grant Date Fair Value Number of Restricted Shares Weighted Average Grant Date Fair Value

The Company recorded $ 755 and $ 735 of share-based compensation expense during the nine months ended September 30, 2025 and 2024, respectively. At September 30, 2025 , the total compensation cost related to unvested awards not yet recognized was $ 1,275 , which was expected to be recognized over the weighted average remaining life of the grants of 2.52 years.

(13) Fair Value Measurement

The Company uses a fair value hierarchy to measure fair value. This hierarchy describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices for identical assets in active markets that are identifiable on the measurement date; Level 2:

Page 29

Civista Bancshares, Inc.

Notes to Interim Consolidated Financial Statements (Unaudited)

Form 10-Q

(Amounts in thousands, except share data)

Significant other observable inputs, such as quoted prices for similar assets, quoted prices in markets that are not active and other inputs that are observable or can be corroborated by observable market data; and Level 3: Significant unobservable inputs that reflect the Company’s own view about the assumptions that market participants would use in pricing an asset.

Debt securities: The fair values of securities available-for-sale are determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs).

Equity securities: The Company’s equity securities are not actively traded in an open market. The fair value of these equity securities available-for-sale not actively traded in an open market is determined by using market data inputs for similar securities that are observable (Level 2 inputs).

Real estate held for sale: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are then reviewed monthly for valuation changes and are accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which may utilize a single valuation approach or a combination of approaches including cost, comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and typically result in a Level 2 classification of the inputs for determining fair value.

Appraisals for both individually analyzed collateral-dependent loans and other real estate owned ("OREO") are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Company’s asset quality or collections department reviews the assumptions and approaches utilized in the appraisal. Appraisal values are discounted from 0 % to 30 % to account for other factors that may impact the value of collateral. In determining the value of individually analyzed collateral dependent loans and OREO, significant unobservable inputs may be used, which include but are not limited to physical condition of comparable properties sold, net operating income generated by the property and investor rates of return.

Swap assets/liabilities: The fair values of interest rate swap positions, both assets and liabilities, are based on valuation pricing models using an income approach reflecting readily observable market parameters such as interest rate yield curves (Level 2).

Collateral Dependent Loans: The Company generally measures the fair value of collateral dependent loans based on the fair value of the loan’s collateral. Fair value is generally determined based upon independent third-party appraisals of the properties. In some cases, management may adjust the appraised value due to the age of the appraisal, changes in market conditions, or observable deterioration of the property since the appraisal was completed. Additionally, management makes estimates about expected costs to sell the property which are also included in the net realizable value. If the fair value of the collateral dependent loan is less than the carrying amount of the loan, a specific reserve for the loan is made in the allowance for credit losses or a charge-off is taken to reduce the loan to the fair value of the collateral (less estimated selling costs) and the loan is included in the table below as a Level 3 measurement.

Fair Value of Financial Instruments

Much of the information used to arrive at “fair value” is highly subjective and judgmental in nature and therefore the results may not be precise. Subjective factors include, among other things, estimated cash flows, risk characteristics and interest rates, all of which are subject to change. With the exception of investment securities, the Company’s financial instruments are not readily marketable and market prices do not exist. Since negotiated prices for the instruments, which are not readily marketable, depend greatly on the motivation of the buyer and seller, the amounts that will actually be realized or paid per settlement or maturity of these instruments could be significantly different.

The carrying amounts of cash and cash equivalents and accrued interest receivable, as a result of their short-term nature, are considered to be equal to fair value and are classified as Level 1.

The carrying amounts of investments in time deposits and loans held for sale are classified as Level 2.

The carrying amount of other securities, which consist of FHLB and other bank stock, approximates fair value as the stock is nonmarketable and has restrictions placed on its transferability.

The Company uses an exit price income approach to determine the fair value of the loan portfolio. The model utilizes a discounted cash flow approach to estimate the fair value of the loans using assumptions for the coupon rates, remaining maturities, prepayment speeds, projected default probabilities, losses given defaults, and estimates of prevailing discount rates. The discounted cash flow approach models the credit losses directly in the projected cash flows. The model applies various assumptions regarding credit, interest, and prepayment risks for the loans based on loan types, payment types and fixed or variable classifications. For all periods presented, the estimated fair value of individually analyzed loans is based on the fair value of the collateral, less estimated cost to sell, or the present value of the loan’s expected future cash flows (discounted at the loan’s effective interest rate). All individually analyzed loans are classified as Level 3 within the valuation hierarchy.

The fair values of noninterest-bearing deposits are considered equal to the amount payable on demand at the reporting date (i.e., carrying value) and are classified as Level 1. The fair value of savings, NOW and certain money market accounts are equal to their carrying amounts and are a Level 1 classification. Fair values of fixed rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 3 classification.

The fair values of subordinated debentures are estimated using a discounted cash flow calculation that applies interest rates currently being offered on subordinated debentures to the schedule of maturities on the subordinated debt tranches resulting in a Level 3 classification.

(14) Derivatives

Risk Management Objective Using Derivatives

The Company is exposed to certain risk arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments.

Interest Rate Swaps Designated as Cash Flow Hedge

The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses interest rate swaps as part of its interest rate risk management strategy. In September 2025, the Company entered into a derivative instrument designated as a cash flow hedge. For a derivative instrument that is designated as a cash flow hedge, the aggregate fair value of the swaps is recorded in swap assets or swap liabilities with changes in fair value recorded in other comprehensive income (loss), net of tax. The amount included in other comprehensive income would be reclassified to current earnings should all or a portion of the hedge no longer be considered effective. For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into earnings in the same period or periods during which the hedged transaction affects earnings.

An interest rate swap with a notional amount totaling $ 100.0 million as of September 30, 2025 was designated as a cash flow hedge to hedge the risk of variability in cash flows (future interest payments) attributable to changes in the contractually specified benchmark interest rate on the Company's short-term fixed rate FHLB advances . The gross aggregate fair value of the swap was $ 52 and is recorded in swap assets in the Consolidated Balance Sheets at September 30, 2025, with changes recorded in other comprehensive income (loss). Amounts reported in accumulated other comprehensive income related to this derivative will be reclassified to interest expense as interest payments are paid on the Company's short-term fixed rate FHLB advances. The hedge was executed to pay fixed and receive variable rate cash flows. The hedge was determined to be effective during the period and the Company expects the hedge to remain effective during the remaining term of the swap. A summary of the interest rate swap designated as a cash flow hedge is presented below (dollars in thousands):

September 30, 2025
Notational amount Cash Flow Hedge $ 100,000
Weighted average fixed pay rates 4.22 %
Weighted average variable SOFR receive rates 4.13 %
Weighted average remaining maturity (in years) 1.5
Fair Value $ 52

Non-designated Hedges

Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. To accommodate customer need and to support the Company’s asset/liability positioning, on occasion the Company enters into interest rate swaps with a customer and a bank counterparty. The interest rate swaps are free-standing derivatives and are recorded at fair value. The Company enters into a floating rate loan and a fixed rate swap with our customer. Simultaneously, the Company enters into an offsetting fixed rate swap with a bank counterparty. In connection with each swap transaction, the Company agrees to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on the same notional amount at a fixed interest rate. At the same time, the Company agrees to pay a bank counterparty the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. These transactions allow the Company’s customer to effectively convert variable rate loans to fixed rate loans. Since the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts offset each other and do not significantly impact the Company’s results of operations. These derivatives are not designated as hedging instruments and changes in fair value are recognized directly in earnings.

The Company presents non-designated derivative positions gross on the balance sheet for customers and net for financial institution counterparty positions subject to master netting arrangements. The fair value on the asset side was reduced by the margin call adjustment per the Company's netting arrangement in the amounts of $ 2,590 and $ 6,330 as of September 30, 2025 and December 31, 2024, respectively.

(Amounts in thousands, except share data)

investments in affordable housing tax credits of $ 416 and $ 461 , respectively.

During the three and nine months ended September 30, 2025 and 2024 , the Company did no t incur any impairment losses related to its investments in qualified affordable housing projects.

(16) Revenue Recognition

The Company accounts for revenues from contracts with customers under ASC 606, Revenue from Contracts with Customers . Revenue associated with financial instruments, including revenue from loans and securities, are outside the scope of ASC 606 and accounted for under other existing GAAP. In addition, certain noninterest income streams such as fees associated with mortgage servicing rights, financial guarantees, derivatives, and certain credit card fees are also not in scope of the guidance. Noninterest revenue streams in-scope of ASC 606 are discussed below.

Service Charges

Service charges consist of account analysis fees (i.e., net fees earned on analyzed business and public checking accounts), monthly service fees, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts.

ATM/Interchange Fees

ATM and Interchange Fees are primarily comprised of debit and credit card income, ATM fees and other service charges. Debit and credit card income is primarily comprised of interchange fees earned whenever the Company’s debit and credit cards are processed through card payment networks such as Mastercard. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a Company ATM. The Company’s performance obligation for ATM and Interchange Fees are largely satisfied, and related revenue recognized, when the services are rendered or upon completion. Payment is typically received immediately or in the following month.

Wealth Management Fees

Wealth management fees are primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received in the following month through a direct charge to customers’ accounts. The Company does not earn performance-based incentives.

Other

Other noninterest income consists of other recurring revenue streams such as check order fees, wire transfer fees, safety deposit box rental fees, item processing fees and other miscellaneous revenue streams. Check order income mainly represents fees charged to customers for checks. Wire transfer fees represent revenue from processing wire transfers. Safe deposit box rental fees are charged to the customer on an annual basis and recognized upon receipt of payment. The Company determined that since rentals and renewals occur fairly consistently over time, revenue is recognized on a basis consistent with the duration of the performance obligation. Item processing fee income represents fees charged to other financial institutions for processing their transactions. Payment is typically received in the following month.

(17) Leases

We have operating leases for several branch locations and office space. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. We also lease certain office equipment under operating leases. Many of our leases include both lease (e.g., minimum rent payments) and non-lease (e.g., common-area or other maintenance costs) components. The Company accounts for each component separately based on the standalone price of each component. In addition, we have several operating leases with lease terms of less than one year and therefore, we have elected the practical expedient to exclude these short-term leases from our right-of-use ("ROU") assets and lease liabilities.

Most leases include one or more options to renew. The exercise of lease renewal options is typically at our sole discretion. The majority of renewals to extend the lease terms are included in our ROU assets and lease liabilities as they are reasonably certain of exercise.

As most of our leases do not provide an implicit rate, we use the fully collateralized FHLB borrowing rate, commensurate with the lease terms based on the information available at the lease commencement date in determining the present value of the lease payments.

The balance sheet information related to our operating leases were as follows as of September 30, 2025 and December 31, 2024:

Classification on the Consolidated Balance Sheet September 30, 2025 December 31, 2024
Assets:
Operating lease Other assets $ 2,562 $ 1,063
Liabilities:
Operating lease Accrued expenses and other liabilities $ 2,562 $ 1,063

The cost components of our operating leases were as follows for the three and nine months ended September 30, 2025 and September 30, 2024:

The weighted average remaining lease terms and discount rates for all of our operating leases were as follows as of September 30, 2025:

Weighted-average remaining lease term-operating leases (years) 3.40
Weighted-average discount rate-operating leases 3.88 %

The Company is the lessor of equipment under operating leases to a wide variety of customers, from commercial and industrial to government and healthcare. The operating lease assets are presented on the balance sheet as premises and equipment. Total cost, net of accumulated depreciation, of leased assets was $ 14,917 and $ 19,136 as of September 30, 2025 and December 31, 2024 , respectively. The Company records lease revenue over the term of the lease and retains ownership of the related assets which are depreciated over the estimated useful life, normally two to six years .

The Company also leases equipment to customers under direct financing leases. At the inception of each lease, the lease receivables, together with the present value of the estimated unguaranteed residual values, are presented on the balance sheet as Loans. The excess of the lease receivables and residual values over the cost of the equipment is recorded as unearned lease income and will be recognized over the lease term, normally two to six years as well.

(18) Segment Reporting

The Company conducts its operations through one single business segment, which is determined by the Chief Financial Officer , who is the designated chief operating decision maker ("CODM").

This decision is based upon information provided about the Company's products and services offered. The segment is also distinguished by the level of information provided to the CODM, who uses such information to review performance of various components of the business, which are then aggregated if operating performance, products/services, and customers are similar. The CODM evaluates revenue streams, significant expenses, and budget to actual results in assessing the Company's segment and in the determination of allocating resources. The CODM uses revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets. The CODM uses consolidated net income to benchmark the Company against its competitors. The benchmarking analysis coupled with monitoring of budget to actual results are used in assessment performance and in establishing compensation. Loans and investments provide the majority of revenues in the banking operation. Interest expense, provision for credit losses, and compensation expense provide the significant expenses in the banking operation.

The Company's segment assets represent its total assets as presented in the Consolidated Balance Sheets.

All of the Company's earnings relate to its operations within the United States.

Agreement and Plan of Merger with The Farmers Savings Bank

On July 10, 2025, CBI and Civista entered into an Agreement and Plan of Merger (the “Merger Agreement”) with The Farmers Savings Bank, an Ohio-chartered bank headquartered in Spencer, Ohio (“Farmers”). Upon the terms and subject to the conditions of the Merger Agreement, at the effective time of the merger (the “Effective Time”), Farmers will merge with and into Civista, with Civista being the surviving bank in the merger (the “FSB Merger”). The acquisition of Farmers will add two branches in Medina and Lorain Counties in Northeast Ohio. As of September 30, 2025, Farmers reported total assets of $293 million, net loans of $106 million, and total deposits of $236 million.

Under the terms and subject to the conditions of the Merger Agreement, which has been unanimously approved by the Boards of Directors of both companies, CBI agreed to pay $34.925 million in cash and issue 1,434,491 common shares, in aggregate, for all of the outstanding Farmers shares, subject to potential adjustment based on Farmers’ equity prior to closing being $56.0 million. This implies an aggregate deal value of approximately $66.7 million based on the closing price of CBI’s common shares on October 24, 2025 of $22.18.

Civista has received all required regulatory approvals for the FSB merger, which is expected to close in November 2025, pending approval by Farmer's shareholders and satisfaction of other customary closing conditions.

Offering of Common Shares

On July 10, 2025, CBI announced an underwritten public offering of up to a maximum of 3,788,238 of its common shares. CBI subsequently closed on the sale of 3,294,120 common shares on July 14, 2025, and the sale of an additional 494,118 common shares on July 16, 2025 pursuant to the underwriters’ exercise of their overallotment option, at the public offering price of $21.25 per share. The aggregate net proceeds from the Offering to CBI were approximately $75.7 million, after deducting $608 of direct expenses and the underwriting discount of $4.2 million. As of September 30, 2025, the net proceeds from the offering was used to pay-down short-term FHLB advances, but the long-term strategic plan is to use the net proceeds for general corporate purposes, which may include supporting organic growth opportunities and future strategic transactions.

Financial Condition

Total assets of the Company at September 30, 2025 were $4,113,334 compared to $4,098,469 at December 31, 2024, an increase of $14,865, or 0.4%. The increase in total assets was mainly due to increases in net loans of $14,179, loans held for sale of $7,347, and securities available-for-sale of $6,549. These increases were partially offset by decreases in premises and equipment of $6,256, other securities of $2,451, deferred taxes of $2,178, and swap assets of $1,624. Total liabilities at September 30, 2025 were $3,614,306 compared to $3,709,967 at December 31, 2024, a decrease of $95,661, or 2.6%. The decrease in total liabilities was primarily attributable to a decrease in short-term FHLB advances of $107,000, partially offset by an increase in total deposits of $18,593.

Loans outstanding as of September 30, 2025 and December 31, 2024 were as follows:

Commercial & Agriculture September 30, 2025 — $ 302,407 $ 328,488 $ (26,081 ) -7.9 %
Commercial Real Estate—Owner Occupied 384,176 374,367 9,809 2.6 %
Commercial Real Estate—Non-Owner Occupied 1,216,031 1,225,991 (9,960 ) -0.8 %
Residential Real Estate 842,362 763,869 78,493 10.3 %
Real Estate Construction 278,163 305,992 (27,829 ) -9.1 %
Farm Real Estate 23,713 23,035 678 2.9 %
Lease Financing Receivables 38,960 46,900 (7,940 ) -16.9 %
Consumer and Other 10,182 12,588 (2,406 ) -19.1 %
Total loans 3,095,994 3,081,230 14,764 0.5 %
Allowance for credit losses (40,254 ) (39,669 ) (585 ) 1.5 %
Net loans $ 3,055,740 $ 3,041,561 $ 14,179 0.5 %

Loans held for sale increased $7,347 since December 31, 2024. The increase was due to increases in both the number of loans and average loan balances held for sale. At September 30, 2025, 25 loans totaling $8,012 were held for sale as compared to 6 loans totaling $665 at December 31, 2024.

Net loans have increased $14,179, or 0.5%, since December 31, 2024. The increase at September 30, 2025 was mainly attributed to increases in one category, Residential Real Estate, partially offset by decreases in Real Estate Construction and Commercial & Agriculture. At September 30, 2025, the loan to deposit ratio was 95.8% compared to 95.9% at December 31, 2024.

During the first nine months of 2025, provisions made to the allowances for credit losses and off-balance sheet credit exposures totaled $2,792, compared to provisions of $4,668 during the same period in 2024. The decrease in the provision for the first nine months of 2025 was primarily the result of a decrease in specific reserves related to one large credit that made a significant paydown during the nine months ended September 30, 2025, in addition to lower net loan growth compared to 2024 and an improvement in delinquencies. CRE non-owner occupied 60 to 89 days past due category decreased from $8,000 to $654 during the nine months ended September 30, 2025. Commercial & Agriculture loan delinquencies decreased during the first nine months of 2025, primarily in the 30-59 days past due category, which decreased from $825 at December 31, 2024 to $112 at September 30, 2025. Residential Real Estate loans past due decreased from $9,411 at December 31, 2024 to $3,929 at September 30, 2025, mainly due to a decrease in delinquencies in 1-4 family first lien loans.

Reserves on the Lease Financing Receivables portfolio decreased at September 30, 2025, primarily related to lower balance growth in 2025 as the leasing division transitioned and focused on converting to a new core operating system. Total delinquencies on Lease Financing Receivables decreased from December 31, 2024 to September 30, 2025. Lease Financing Receivables 30-59 days past due and 60-89 days past due combined decreased from $926 to $327, and the balance of 90 days or greater past due also decreased from $909 to $449. Nonaccrual Lease Financing Receivables decreased from $1,238 at December 31, 2024 to $807 at September 30, 2025.

Net charge-offs for the first nine months ended September 30, 2025 totaled $2,212, compared to net charge-offs of $1,080 for the same period of 2024. For the first nine months ended September 30, 2025, the Company charged off a total of 45 loans and leases, consisting of 16 Commercial & Agriculture loans totaling $684, ten Lease Financing Receivables totaling $546, two Commercial Real Estate – Non-Owner Occupied loans totaling $1,350, 12 Consumer and Other loans totaling $20 and five Residential Real Estate totaling $130. The Commercial Real Estate - Non-Owner Occupied charge-offs of $1,350 are related to two loans that were previously identified and actively monitored by management, classified as nonaccrual and individually evaluated as of both December 31, 2024 and September 30, 2025. In addition, during the nine months ended September 30, 2025, the Company had recoveries on previously charged-off Commercial & Agriculture loans of $375, Commercial Real Estate – Non-Owner Occupied loans of $3, Residential Real Estate loans of $76, Leasing Financing Receivables of $43 and Consumer and Other loans of $21. For each loan category, as well as in total, the percentage of net charge-offs to loans was less than one percent. Each of these factors was considered by management as part of the examination of both the level and mix of the allowance by credit type as well as the overall level of the allowance.

Management specifically evaluates loans that do not share common risk characteristics for estimates of loss. To evaluate the adequacy of the allowance for credit losses to cover probable losses in the loan portfolio, management considers specific reserve allocations for identified portfolio loans, reserves for delinquencies and historical reserve allocations. Loss migration rates are calculated over a three-year period for all portfolio segments. Management also considers certain economic factors for trends that management uses to account for the qualitative and environmental changes in risk, which affects the level of the reserve.

Larger (greater than $350) Commercial & Agricultural and Commercial Real Estate loan relationships, as well as Residential Real Estate and Consumer loans and Lease Financing Receivables that are part of a larger relationship are individually evaluated on a quarterly basis, when they do not share similar risk characteristics with the collectively evaluated pools. These loans are analyzed to determine if it is probable that all amounts will not be collected according to the contractual terms of the loan agreement. If management determines that the value of the loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance estimate or a charge-off to the allowance. The Company’s policy for recognizing interest income on individually evaluated loans does not differ from its overall policy for interest recognition. Loans held for sale are excluded from consideration as individually evaluated. Loans are generally moved to nonaccrual status when 90 days or more past due. Loans, or portions thereof, are charged-off when deemed uncollectible. The allowance for credit losses as a percent of total loans was 1.30% at September 30, 2025 and 1.29% at December 31, 2024.

The available-for-sale securities portfolio increased by $6,549, from $648,067 at December 31, 2024 to $654,616 at September 30, 2025. Management continually evaluates our securities portfolio in response to established asset/liability management objectives, changing market conditions that could affect profitability, and the level of interest rate risk to which the Company is exposed. These evaluations may cause the Company to change the level of funds it deploys into investment securities and change the composition of its investment securities portfolio. As of September 30, 2025, the Company was in compliance with all pledging requirements.

Premises and equipment, net, decreased $6,256 from December 31, 2024 to September 30, 2025. The decrease was mainly the result of depreciation expenses of $5,201 coupled with maturing operating leases, partially offset by purchases. The decrease in depreciation was mainly attributable to leasing operations as operating leases matured. Since mid-2024, new lease originations have primarily consisted of finance leases which are recorded in Loans on the Consolidated Balance Sheets.

Swap assets decreased $1,624 from December 31, 2024 to September 30, 2025. The decrease was primarily the result of a decline in market value.

Total deposits as of September 30, 2025 and December 31, 2024 were as follows:

The Company had approximately $512,458 and $431,713 of uninsured deposits as of September 30, 2025 and December 31, 2024, respectively. Uninsured deposit amounts are estimated based on the portions of customer account balances that exceed the FDIC insurance limit of $250.

Total deposits at September 30, 2025 increased $18,593 from December 31, 2024. Noninterest-bearing deposits, brokered deposits, and interest-bearing demand deposits decreased $43,160, $69,098, and $3,963, respectively, from December 31, 2024, while time deposits and savings and money markets increased $131,803 and $3,011, respectively, from December 31, 2024. The decrease in noninterest-bearing deposits was primarily due to a $46,104 decrease in noninterest-bearing business accounts, partially offset by an increase of $5,883 in noninterest-bearing public funds accounts. The decrease in interest-bearing demand deposits was primarily due to a decrease of $16,586 in Jumbo NOW and interest-bearing checking accounts, mostly offset by an increase in interest-bearing public funds accounts of $14,067. The $131,803 increase in time deposits was due to increases of $94,622 in jumbo time deposits and a $43,113 increase in retail time deposits, which were slightly offset by a decrease of $6,779 in reciprocal time deposits. The $3,011 increase in savings and money market accounts was primarily due to a $51,994 increase in business money market accounts, mostly offset by decreases of $36,493 in ICS demand and money market, $724 in retail money market savings, $7,110 in retail statement savings, and $3,958 in business savings accounts. The year-to-date average balance of total deposits increased $190,335, compared to the average balance for the same period in 2024, mainly due to increases of $162,887 in the average balance of demand and savings deposits and $67,482 in time deposits, partially offset by a $40,034 decrease in the average balance of noninterest-bearing deposits.

Short-term FHLB advances decreased $107,000 from December 31, 2024 to September 30, 2025, primarily as a result of the cash received from the capital raise that was completed in the third quarter of 2025.

Swap liabilities decreased $5,416 from December 31, 2024 to September 30, 2025. The decrease was the result of a decrease in fair value of swap liabilities.

Shareholders’ equity at September 30, 2025 was $499,028, or 12.1% of total assets, compared to $388,502, or 9.5% of total assets, at December 31, 2024. The increase was a result of net income of $33,943 coupled with $75,666 resulting from the capital raise completed in the third quarter of 2025, partially offset by dividends paid on common shares of $8,553.

Total outstanding common shares at September 30, 2025 were 19,312,726, which increased from 15,487,667 common shares outstanding at December 31, 2024. Common shares outstanding increased due to the issuance of 3,788,238 shares in the capital raise and the grant of 49,857 restricted common shares to certain officers under the Company’s 2024 Incentive Plan, partially offset by 8,716 common shares surrendered by officers to the Company to pay taxes upon vesting of restricted shares and 4,320 forfeited shares.

Results of Operations

Net interest income for the three months ended September 30, 2025 was $34,545, an increase of $5,312 from $29,233 for the same period of 2024. This increase was a result of an increase of $2,499 in total interest and dividend income, coupled with a $2,813 decrease in total interest expense. Total interest-earning assets averaged $3,829,484 during the three months ended September 30, 2025, an increase of $123,618 from $3,705,866 for the same period of 2024. The Company’s total average interest-bearing liabilities increased from $2,898,978 during the three months ended September 30, 2024 to $2,957,458 during the three months ended September 30, 2025. The Company’s fully tax equivalent net interest margin for the three months ended September 30, 2025 and 2024 was 3.58% and 3.16%, respectively.

Total interest and dividend income was $55,240 for the three months ended September 30, 2025, an increase of $2,499 from $52,741 for the same period of 2024. The increase in interest and dividend income is attributable to a $1,820 increase in interest and fees on loans and a $664 increase in interest income on taxable securities. The $1,820 increase in interest and fees on loans is attributable to an increase in the average balance of loans. The average balance of loans increased by $96,149, or 3.2%, to $3,128,033 for the three months ended September 30, 2025, as compared to $3,031,884 for the same period of 2024.

Interest on taxable securities increased $664 to $3,922 for the three months ended September 30, 2025, compared to $3,258 for the same period of 2024. The average balance of taxable securities increased $38,632 to $402,216 for the three months ended September 30, 2025, as compared to $363,584 for the same period of 2024. The yield on taxable securities increased 33 basis points to 3.57% for the three months ended September 30, 2025, compared to 3.24% for the same period of 2024, resulting from the purchase of similar securities to replace matured securities with the new securities having higher rates than when the matured securities were originally purchased. Interest on tax-exempt securities decreased $45 to $2,324 for the three months ended September 30, 2025, compared to $2,369 for the same period of 2024. The average balance of tax-exempt securities decreased $16,532 to $274,722 for the three months ended September 30, 2025, as compared to $291,254 for the same period of 2024. The yield on tax-exempt securities increased 1 basis point to 3.84% for the three months ended September 30, 2025, compared to 3.83% for the same period of 2024.

Total interest expense decreased $2,813, or 12.0%, to $20,695 for the three months ended September 30, 2025, compared to $23,508 for the same period of 2024. For the three months ended September 30, 2025, the average balance of interest-bearing liabilities increased $58,480 to $2,957,458, as compared to $2,898,978 for the same period of 2024. Interest incurred on deposits decreased by $579 to $16,347 for the three months ended September 30, 2025, compared to $16,926 for the same period of 2024. The average balance of interest-bearing deposits increased by $168,934 to $2,574,153 for the three months ended September 30, 2025, as compared to the same period in 2024, slightly offset by a decrease in the rate paid on time deposits from 5.37% in 2024 to 4.01% in 2025. The decrease in rates on time deposits was primarily related to paying lower rates on retail and brokered CDs due to the lower rate environment in the third quarter of 2025 compared to the same period of 2024. Interest expense incurred on short-term FHLB advances decreased mainly due to the cash received from the capital raise which subsequently paid down short-term FHLB advances in the third quarter of 2025 and a decrease in rate paid because of the yield curve shifting downwards in 2025 compared to the same period of 2024.

The following table presents the condensed average balance sheets for the three months ended September 30, 2025 and 2024. The daily average loan amounts outstanding are net of unearned income and include loans held for sale and nonaccrual loans. The average balance of securities is computed using the carrying value of securities. Rates are annualized and taxable equivalent yields are computed using

to the same period of 2024, mainly due to leasing originations being strategically curtailed in 2025 resulting from the CLF core system conversion. The core system conversion was completed late in the second quarter of 2025.

Noninterest expense for the three month periods ended September 30, 2025 and 2024 was as follows:

Three Months Ended September 30, — 2025 2024 $ Change % Change

Other 3,604 $ 3,323 281 8.5 %
Total noninterest expense $ 28,327 $ 28,395 $ (68 ) -0.2 %

Total noninterest expense for the three months ended September 30, 2025 was $28,327, a decrease of $68, or 0.2%, from $28,395 reported for the same period of 2024. The decrease in total noninterest expense was primarily due to decreases in compensation and marketing expenses, mostly offset by increases in software maintenance and other expenses. The decrease in compensation expense was primarily due to an increase in the deferral of salaries and wages related to the loan originations in the third quarter of 2025. The decrease in marketing expense was mainly due to lower marketing and promotional expenses related to advertising and product marketing. The increase in software maintenance expenses was primarily a function of the renewal of current contracts at higher levels as we continue to enhance our systems and products to meet customer demand as well as create efficiencies for our employees. The increase in other expenses are mainly related to the non-recurring acquisition-related expense for the FSB Merger.

Income tax expense for the three months ended September 30, 2025 totaled $2,891, up $1,340 compared to the same period of 2024. The effective tax rates for the three month periods ended September 30, 2025 and 2024 were 18.5% and 15.6%, respectively. The increase in the effective tax rate for the three month period ended September 30, 2025, was primarily due to an increase in the forecasted pre-tax income outpacing the permanent differences for 2025, thus, creating more taxable income at the statutory tax rate of 21% and increasing the Company's effective tax rate. The difference between the statutory federal income tax rate and the Company’s effective tax rate is the permanent tax differences, primarily consisting of tax-exempt interest income from municipal investments and loans, low-income housing tax credits, tax-deductible captive insurance premiums and bank owned life insurance income.

The change in interest expense can be attributed to a decrease in rate, mostly offset by an increase in the average balance of interest-bearing liabilities. For the nine months ended September 30, 2025, the average balance of interest-bearing liabilities increased $196,480 to $3,007,668, compared to $2,811,188 for the nine months ended September 30, 2024.

Total noninterest income for the nine months ended September 30, 2025 was $24,082, a decrease of $4,651, or 16.2%, from $28,733 for the same period of 2024. Lease revenue and residual income decreased $3,274 for the nine months ended September 30, 2025, compared to the same period of 2024, mainly due to curtailing lease originations in 2025 while CLF implemented a new core operating system coupled with stronger lease originations in 2024, and a one-time non-recurring adjustment decreasing leasing revenue by $1,044 associated with CLF's core system conversion. Other income decreased $1,276 for the nine months ended September 30, 2025, compared to the same period of 2024, mostly related to lower fee revenue from CLF.

Other 9,435 9,521 (86 ) -0.9 %
Total noninterest expense $ 82,935 $ 84,225 $ (1,290 ) -1.5 %

Total noninterest expense for the nine months ended September 30, 2025 was $82,935, a decrease of $1,290, or 1.5%, from $84,225 reported for the same period of 2024. The decrease in total noninterest expense was primarily due to decreases in compensation expense and equipment expense, somewhat offset by increases in professional services. The decrease in compensation expense was primarily due to an increase in the deferral of salaries and wages related to loan originations in the first nine months of 2025 coupled with a decrease in the average number of full-time equivalent employees to 523 at September 30, 2025, compared to 531 for the same period of 2024, resulting in lower compensation and benefits costs. The decrease in equipment expense was primarily due to the $1,616 decrease in expenses related to operating lease contracts, which was partially offset by $737 in depreciation expense recorded to write down the net book value of certain assets identified as no longer in use. The increase in professional fees was attributable to utilizing consultants to assist in the transitioning of the new core operating system at CLF.

Income tax expense for the nine months ended September 30, 2025 totaled $6,544, up $3,138 compared to the same period of 2024. The effective tax rates for the nine months ended September 30, 2025 and 2024 were 16.2% and 13.5%, respectively. The increase in the effective tax rate for the nine month period ended September 30, 2025, was primarily due to an increase in the forecasted pre-tax income outpacing the permanent differences for 2025, thus, creating more taxable income at the statutory tax rate of 21% and increasing the Company's effective tax rate. The difference between the statutory federal income tax rate and the Company’s effective tax rate is the permanent tax differences, primarily consisting of tax-exempt interest income from municipal investments and loans, low-income housing tax credits, tax-deductible captive insurance premiums and bank owned life insurance income.

Capital Resources

Shareholders’ equity totaled $499,028 at September 30, 2025, compared to $388,502 at December 31, 2024. Shareholders’ equity increased during the first nine months of 2025 as a result of net income of $33,943 coupled with $75,666 resulting from the capital raise completed in the third quarter of 2025, partially offset by dividends on common shares of $8,553.

Liquidity

The Company maintains a conservative liquidity position. All securities, with the exception of equity securities, are classified as available-for-sale. Securities, with maturities of one year or less, totaled $29,753, or 4.55% of the total securities portfolio, at September 30, 2025. The available-for-sale securities portfolio helps to provide the Company with the ability to meet its funding needs. The Condensed Consolidated Statements of Cash Flows (Unaudited) contained in the Consolidated Financial Statements detail the Company’s cash flows from operating activities resulting from net earnings.

As reported in the Condensed Consolidated Statements of Cash Flows (Unaudited), our cash flows are classified for financial reporting purposes as operating, investing or financing cash flows. Net cash provided by operating activities was $33,661 and $25,850 for the nine months ended September 30, 2025 and 2024, respectively. The primary additions to cash from operating activities are from proceeds from the sale of loans. The primary use of cash from operating activities is from loans originated for sale. Net cash used for investing activities was $10,457 and $187,303 for the nine months ended September 30, 2025 and 2024, respectively, principally reflecting our loan and investment security activities. Cash (used)/provided by financing activities was ($23,593) and $175,709 for the nine months ended September 30, 2025 and 2024, respectively. The primary changes in financing activities is the decrease in short-term FHLB advances and the payment of common dividends, mostly offset by cash provided by proceeds from the capital raise as well as an increase in deposits.

Future loan demand of Civista may be funded by increases in deposit accounts, proceeds from payments on existing loans, the maturity of securities, and the sale of securities classified as available-for-sale. Additional sources of funds may also come from borrowing in the Federal Funds market and/or borrowing from the FHLB. Through its correspondent banks, Civista maintains federal funds borrowing lines totaling $50,000. As of September 30, 2025, Civista had total credit availability with the FHLB of $966,116 with standby letters of credit totaling $115,000 and a remaining borrowing capacity of approximately $618,147. In addition, CBI maintains a credit line with a third party lender totaling $10,000. No borrowings were outstanding by CBI under this credit line as of September 30, 2025.

Quantitative and Qualitative Disclosures About Market Risk

ITEM 3. Quantitative and Qualitat ive Disclosures About Market Risk

The Company’s primary market risk exposure is interest-rate risk and, to a lesser extent, liquidity risk. All of the Company’s transactions are denominated in U.S. dollars with no specific foreign exchange exposure.

Interest-rate risk is the exposure of a banking organization’s financial condition to adverse movements in interest rates. Accepting this risk can be an important source of profitability and shareholder value. However, excessive levels of interest-rate risk can pose a significant threat to the Company’s earnings and capital base. Accordingly, effective risk management that maintains interest-rate risk at prudent levels is essential to the Company’s safety and soundness.

Evaluating a financial institution’s exposure to changes in interest rates includes assessing both the adequacy of the management process used to control interest-rate risk and the organization’s quantitative level of exposure. When assessing the interest-rate risk management process, the Company seeks to ensure that appropriate policies, procedures, management information systems and internal controls are in place to maintain interest-rate risk at prudent levels with consistency and continuity. Evaluating the quantitative level of interest rate risk exposure requires the Company to assess the existing and potential future effects of changes in interest rates on its consolidated financial condition, including capital adequacy, earnings, liquidity and, where appropriate, asset quality.

The Federal Reserve Board, together with the Office of the Comptroller of the Currency and the Federal Deposit Insurance Corporation, issue policy statements and guidance on sound practices for managing interest-rate risk, which form the basis for ongoing evaluation of the adequacy of interest-rate risk management at supervised institutions. The guidance also outlines fundamental elements of sound management and discusses the importance of these elements in the context of managing interest-rate risk. The guidance emphasizes the need for active board of director and senior management oversight and a comprehensive risk-management process that effectively identifies, measures, and controls interest-rate risk.

Financial institutions derive their income primarily from the excess of interest collected over interest paid. The rates of interest an institution earns on its assets and owes on its liabilities generally are established contractually for a period of time. Since market interest rates change over time, an institution is exposed to lower profit margins (or losses) if it cannot adapt to interest-rate changes. For example, assume that an institution’s assets carry intermediate- or long-term fixed rates and that those assets were funded with short-term liabilities. If market interest rates rise by the time the short-term liabilities must be refinanced, the increase in the institution’s interest expense on its liabilities may not be sufficiently offset if assets continue to earn at the long-term fixed rates. Accordingly, an institution’s profits could decrease on existing assets because the institution will have either lower net interest income or, possibly, net interest expense. Similar risks exist when assets are subject to contractual interest-rate ceilings, or rate sensitive assets are funded by longer-term, fixed-rate liabilities in a decreasing-rate environment.

Several techniques may be used by an institution to minimize interest-rate risk. One approach used by the Company is to periodically analyze its assets and liabilities and make future financing and investment decisions based on payment streams, interest rates, contractual maturities, and estimated sensitivity to actual or potential changes in market interest rates. Such activities fall under the broad definition of asset/liability management. The Company’s primary asset/liability management technique is the measurement of the Company’s asset/liability gap, that is, the difference between the cash flow amounts of interest sensitive assets and liabilities that will be refinanced (or repriced) during a given period. For example, if the asset amount to be repriced exceeds the corresponding liability amount for a certain day, month, year, or longer period, the institution is in an asset sensitive gap position. In this situation, net interest income would increase if market interest rates rose or decrease if market interest rates fell. If, alternatively, more liabilities than assets will reprice, the institution is in a liability sensitive position. Accordingly, net interest income would decline when rates rose and increase when rates fell. Also, these examples assume that interest rate changes for assets and liabilities are of the same magnitude, whereas actual interest rate changes generally differ in magnitude for assets and liabilities.

Several ways an institution can manage interest-rate risk include selling existing assets or repaying certain liabilities; matching repricing periods for new assets and liabilities, for example, by shortening terms of new loans or securities; and hedging existing assets, liabilities, or anticipated transactions. An institution might also invest in more complex financial instruments intended to hedge or otherwise change interest-rate risk. Interest rate swaps, futures contracts, options on futures, and other such derivative financial instruments often are used for this purpose. Because these instruments are sensitive to interest rate changes, they require management expertise to be effective. Financial institutions are also subject to prepayment risk in falling rate environments. For example, mortgage loans and other financial assets may be prepaid by a debtor so that the debtor may refinance its obligations at new, lower rates. Prepayments of assets carrying higher rates reduce the Company’s interest income and overall asset yields. A large portion of an institution’s liabilities may be short-term or due on demand, while most of its assets may be invested in long-term loans or securities. Accordingly, the Company seeks to have in place, sources of cash to meet short-term demands. These funds can be obtained by increasing deposits, borrowing, or selling assets. FHLB advances and wholesale borrowings may also be used as important sources of liquidity for the Company.

The following table provides information about the Company’s financial instruments that were sensitive to changes in interest rates as of December 31, 2024 and September 30, 2025, based on certain prepayment and account decay assumptions that management believes are reasonable. The table shows the changes in the Company’s net portfolio value (in amount and percent) that would result from hypothetical interest rate increases of up to 400 basis points from 100 basis points and interest rate decreases of 100 basis points and up to 400 basis points at September 30, 2025 and December 31, 2024.

-400bp 803,744 83,664 11.6 % 593,087 (10,140 ) (1.7 %)

The change in net portfolio value from December 31, 2024 to September 30, 2025, can be attributed to a couple of factors. The volume of assets and funding sources has changed, but the asset mix remains centered on loan and deposits. The volume of loans and deposits has increased, while the volume of short-term FHLB advances has decreased. The volume shifts from the end of the year contributed to an increase in the base net portfolio value. Additionally, the Company completed its underwritten public offering of common shares in the third quarter of 2025 resulting in aggregate net proceeds of approximately $75.7 million. Beyond the change in the base level of net portfolio value, projected movements in rates, up or down, would also lead to changes in market values. The change in the rates up scenarios for the 100, 200, 300 and 400 basis point movements would lead to a slightly larger increase in the market value of liabilities than assets. Accordingly, the Company sees an increase in the net portfolio value. The change in the rates down scenarios for the 100 and 200 basis point movements would lead to a larger decrease in the market value of liabilities than in assets, leading to a decrease in the net portfolio value with the exception of the down 300 and 400 basis point which has a higher market value of assets then liabilities.
