On July 1, 2025, Old Second Bancorp, Inc. ("Old Second") filed a Current Report on Form 8-K (the "Initial Filing") to report that Old Second had completed its acquisition of Bancorp Financial, Inc. ("Bancorp Financial"), pursuant to the Agreement and Plan of Merger, dated as of February 24, 2025 (the "Merger Agreement") by and between Old Second and Bancorp Financial. Pursuant to the terms of the Merger Agreement, effective July 1, 2025, Bancorp Financial merged with and into Old Second (the "Merger"), with Old Second continuing as the surviving corporation in the Merger.

**Notes to Consolidated Financial Statements (Unaudited)**

#### Note 1. Summary of Significant Accounting Policies
**Principles of consolidation and nature of business:** The consolidated financial statements of Bancorp Financial, Inc. (the Company) include the accounts of the Company and its subsidiary. The Company is a bank holding company whose principal activity is the ownership and management of its wholly-owned subsidiary, Evergreen Bank Group (the Bank), formerly known as Evergreen Private Bank and Evergreen Community Bank. The Bank has a subsidiary, EB Group, LLC, that has been established to hold other real estate owned. All significant intercompany accounts and transactions have been eliminated in consolidation.

**Nature of operations:** The Bank generates residential, commercial and consumer loans. A substantial portion of the loan portfolio is represented by a nationwide powersport portfolio originated through a network of powersport dealers. The Bank receives deposits from customers located primarily in the Chicago Metropolitan area in addition to online savings deposits nationwide and utilizing the brokered deposit market. The Bank operates under an Illinois state bank charter and is subject to regulation by the Illinois Department of Financial and Professional Regulation and the Federal Deposit Insurance Corporation (FDIC).

**Basis of financial statement presentation and accounting estimates:** The unaudited consolidated financial statements include the accounts of Bancorp Financial, Inc. and the Bank. Significant intercompany accounts and transactions have been eliminated.

The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America (GAAP). In preparing the accompanying consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenue and expenses for the reporting period. The significant estimate that is particularly susceptible to change in a short period of time relates to the determination of the allowance for credit losses. Actual results could differ from this estimate.

In the opinion of management, the consolidated financial statements contain all the normal and recurring adjustments necessary for a fair statement of the financial position of the Company as of June 30, 2025 and December 31, 2024, and the results of its operations for the six months ended June 30, 2025 and 2024. Interim results do not necessarily represent annual results. Certain information and disclosures normally included in notes to consolidated annual financial statements prepared in accordance with U.S. GAAP have been condensed or omitted in these interim consolidated financial statements. These financial statements should be read in conjunction with Company's Audited Financial Statements for the year ended December 31, 2024.

**Presentation of cash flows:** For purposes of the consolidated statements of cash flows, cash and cash equivalents include cash and balances due from banks, interest-bearing deposits in other banks and federal funds sold. Cash flows from FHLB stock, loans and deposits are reported net.

**Securities available for sale:** Securities classified as available for sale are those securities that the Company intends to hold for an indefinite period of time, but not necessarily to maturity. Decisions to sell a security classified as available for sale would be based on various factors, including significant movements in interest rates, changes in the maturity mix of the Company's assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Securities available for sale are reported at fair value with unrealized gains or losses reported as accumulated other comprehensive income, net of the related deferred tax effect.

Purchase discounts are recognized in interest income using the interest method over the terms of the securities. Purchase premiums are recognized in interest income using the interest method over the earlier of the terms of the securities or the call date when applicable. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

**Notes to Consolidated Financial Statements (Unaudited)**

Debt securities available for sale are not within the scope of the current expected credit losses methodology, however, the accounting for credit losses on these securities is affected by ASC Subtopic 326-30 "Financial Instruments-Credit Losses-Available-for-Sale Debt Securities." A debt security available for sale is impaired if the fair value of the security declines below its amortized cost basis. To determine the appropriate accounting, the Company must first determine if it intends to sell the security or if it is more likely than not that it will be required to sell the security before the fair value increases to at least the amortized cost basis. If either of those selling events is expected, the Company will write down the amortized cost basis of the security to its fair value. This is achieved by writing off any previously recorded allowance, if applicable, and recognizing any incremental impairment through earnings. If the Company neither intends to sell the security, nor believes it more likely than not that it will be required to sell the security, before the fair value recovers to the amortized cost basis, the Company must determine whether any of the decline in fair value has resulted from a credit loss, or if it is entirely the result of noncredit factors.

The Company considers the following factors in assessing whether the decline is due to a credit loss:

● Extent to which the fair value is less than the amortized cost basis

● Adverse conditions specifically related to the security, an industry, or geographic area (for example, changes in the financial condition of the issuer of the security, or in the case of an asset backed debt security, in the financial condition of the underlying loan obligors)

● Payment structure of the debt security and the likelihood of the issuer being able to make payments that increase in the future

● Failure of the issuer of the security to make scheduled interest or principal payments

● Any changes to the rating of the security by a rating agency

Impairment related to a credit loss must be measured using the discounted cash flow method. Credit loss recognition is limited to the fair value of the security. Impairment is recognized by establishing an allowance for credit losses (ACL) through provision for credit losses. Impairment related to noncredit factors is recognized in other comprehensive income (OCI), net of applicable taxes. The Company did not recognize any impairment for the six month periods ended June 30, 2025 or 2024.

**Federal Home Loan Bank stock:** The Company, as a member of the Federal Home Loan Bank of Chicago (FHLB), is required to maintain an investment in capital stock of the FHLB. The stock does not have a readily determinable fair value as ownership is restricted and it lacks a ready market. As a result, this stock is carried at cost and evaluated periodically for impairment.

**Loans:** Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for credit losses, and net deferred origination fees. Interest income is accrued on the unpaid principal balance. Net deferred origination fees are recognized as an adjustment of the related loan yield using the interest method.

The Company's loan portfolio is segmented as follows:

● Commercial and industrial

● Commercial real estate

● Construction and development

● Residential real estate

● Home equity loans and lines of credit

● Powersport

● Installment and other

Generally, loans are considered past due when contractual payments are delinquent for 30 days or greater.

[**Table of Contents**](#TOC)

**Bancorp Financial, Inc. and Subsidiary**

**Notes to Consolidated Financial Statements (Unaudited)**

**Note 1. Summary of Significant Accounting Policies (continued)**

The accrual of interest on all loans, except for powersport loans and certain installment loans, is discontinued at the time the loan is 90 days past due (unless the credit is well-secured and in process of collection); or if any of the following conditions exist:

● It becomes evident that the borrower will not make payments, or will not or cannot meet the terms for renewal of a matured loan;

● When full repayment of principal and interest is not expected;

● When the loan is graded "substandard", is more than 30 days delinquent and the future accrual of interest is not protected by sound collateral values;

● When the loan is graded "doubtful";

● When the borrower files bankruptcy and an approved plan of reorganization or liquidation is not anticipated in the near future; or

● When foreclosure action is initiated.

All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current, the loan is well secured and in the process of collection and future principal and interest payments are not in doubt.

Powersport loans and certain installment loans are not put on nonaccrual status. These loans are charged-off at the earlier of the time management determines a loss or when the loan becomes 120 days delinquent. Powersport and certain installment loans where the borrower has filed a chapter 13 bankruptcy may remain as an active loan until it becomes past due over 180 days.

**Allowance for credit losses:** The ACL is established based upon the Company's current estimate of expected lifetime credit losses on loans measured at amortized cost. The ACL on loans is increased by charges to provision for credit losses and reduced by charge-offs, net of recoveries. Management evaluates the appropriateness of the ACL on the loans quarterly. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change from period to period. The ACL represents the Company's estimated risk of loss within the loan portfolio as of the reporting date. To appropriately measure expected credit losses, management disaggregates the loan portfolio into pools of similar risk characteristics or segments. These segments are established based on a variety of factors including, but not limited to, underwriting standards, collateral, and associated risks of certain portfolios. These risk categories and the relevant risk characteristics are as follows:

<u>Commercial and industrial</u> – Commercial and industrial loans are loans for commercial, corporate and business purposes, including issuing letters of credit. The Company's commercial business loan portfolio is comprised of loans for a variety of purposes and generally is secured by equipment, machinery and other business assets. Commercial business loans generally have terms of five years or less and interest rates that float in accordance with a designated published index. Substantially all of such loans are secured and backed by the personal guarantees of the owners of the business or the SBA.

<u>Commercial real estate</u> – Commercial real estate loans are primarily secured by apartment buildings, office and industrial buildings, warehouses, and various special purpose properties. Although terms vary, commercial real estate loans generally have amortizations of 20 to 25 years, as well as balloon payments of two to five years, and terms which provide that the interest rates thereon may be adjusted based on a designated index.

**Bancorp Financial, Inc. and Subsidiary**

**Notes to Consolidated Financial Statements (Unaudited)**

**Note 1. Summary of Significant Accounting Policies (continued)**

<u>Construction and development</u> – Construction and development loans are primarily secured by land or building construction in process. Although terms vary, construction and development loans generally are interest only, as well as balloon payments of one to three years, and terms which provide that the interest rates thereon may be adjusted at the Company's discretion, based on a designated index. Upon completion of the project, the loan may be converted to a commercial real estate loan by the Company or another lender.

<u>Residential real estate</u> – Residential real estate loans are generally smaller in size and are secured by nonfarm property containing one to four family dwelling units which include individual condominium dwelling units secured by an interest in the individual housing unit.

<u>Home equity loans and lines of credit</u> – Home equity loans and lines of credit are secured by residential real estate with a term normally ten years or less. Due to higher risk involved, home equity loans and lines of credit generally have higher interest rates than residential real estate mortgages.

<u>Powersport</u> – Powersport loans are originated through a network of dealers throughout the United States. These loans are primarily secured by motorcycles and off-road vehicles and generally have higher interest rates than mortgage loans. The risk involved in powersport loans is the type and nature of the collateral and, in certain cases, the absence of collateral.

<u>Installment and other</u> – Installment and other loans include both secured and unsecured loans that have been made for a variety of consumer purposes. Secured loans includes consumer loans purchased, solar loans purchased, collector car loans, manufactured housing loans and loans against marketable securities. The risk involved in installment and other loans is the type and nature of the collateral and, in certain cases, the absence of collateral.

***Determining the Allowance for Credit Losses:*** The ACL is measured based upon management's loan portfolio segmentation. The Company utilizes modeling methodologies that include quantitative analysis to estimate lifetime credit loss rates on each segment, based on origination year utilizing historical charge off percentages. The net-charge off percentage is applied to the outstanding balances to use in the calculation of the ACL for each loan segment.

Credit quality indicators, specifically the Company's internal risk rating systems, reflect how the Company monitors credit losses and represent factors used by the Company when measuring the allowance for credit losses. Historical credit loss history is adjusted to incorporate reasonable and supportable third party economic forecasts on a qualitative basis. Reasonable and supportable forecasts consider the macroeconomic factors that are most relevant to evaluating and predicting expected credit losses in the Company's financial assets.

Qualitative factors assessed by management include the following:

● Economic factors;

● Changes in lending policies and procedures, including changes in underwriting standards and collections, charge-offs, and recovery practices;

● Changes in the experience, depth, and ability of lending management;

● Changes in the nature and volume of the portfolio and terms of loans;

● Changes in the quality of the organization's loan review system;

● Changes in the value of underlying collateral for collateral dependent loans;

● Changes in the volume and severity of past due loans and other similar conditions;

● The effect of other external factors (i.e. competition, legal and regulatory requirements) on the level of estimated credit losses; and

● The existence and effect of any concentrations of credit and changes in the levels of such concentrations.

**Note 1. Summary of Significant Accounting Policies (continued)**

Individually evaluated loans are based on Criticized Asset Reports prepared for all watch list commercial loans, watch list Home Equity loans greater than $100,000, loans on non-accrual status, and loans delinquent 90 days or greater. No powersport loans are individually evaluated for impairment. These Criticized Asset Reports evaluate the collateral held and document if any specific reserve needs to be made for each individual loan.

The Company categorizes commercial and industrial, commercial real estate, construction and development, and consumer watch list loans into the following risk categories based on relevant information about the ability of borrowers to service their debt:

<u>Pass</u> – A Pass asset is well protected by the current worth and paying capacity of the obligor (or guarantors, if any) or by the fair value, less cost to acquire and sell, of any underlying collateral in a timely manner. Pass assets also include certain assets considered watch, which are still protected by the worth and paying capacity of the borrower but deserve closer attention and a higher level of credit monitoring.

<u>Special Mention</u> – A Special Mention asset has potential weaknesses that deserve management's close attention. The asset may also be subject to a weak or speculative market or to economic conditions, which may, in the future, adversely affect the obligor. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company's credit position at some future date. Special Mention assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

<u>Substandard – Accrual</u> – A Substandard - Accrual asset is an asset with a well-defined weakness that jeopardizes repayment, in whole or in part, of the debt. Payments are either delinquent, but are being made, or the obligation is both well secured and in the process of collection. These assets are characterized by the distinct possibility that the Company will sustain some loss of principal and/or interest if the deficiencies are not corrected. It is not necessary for a loan to have an identifiable loss potential in order to receive this rating.

<u>Substandard – Non-Accrual</u> – A Substandard – Non-Accrual asset is an asset with a well-defined weakness that jeopardizes repayment, in whole or in part, of the debt. These credits are inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged. One or more payments are 90 days past due, and the obligation is not well secured. These assets are characterized by the distinct possibility that the Company will sustain some loss of principal and/or interest if the deficiencies are not corrected. It is not necessary for a loan to have an identifiable loss potential in order to receive this rating.

<u>Doubtful</u> – An asset that has all the weaknesses inherent in the Substandard classification, 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. The possibility of loss is extremely likely, but the magnitude is not identified at this point due to pending factors.

<u>Loss</u> – An asset, or portion thereof, classified as Loss is considered uncollectible and of such little value that its continuance on the Company's books as an asset is not warranted. This classification does not necessarily mean that an asset has no recovery or salvage value; but rather, there is much doubt about whether, how much, or when the recovery would occur. As such, it is not practical or desirable to defer the write-off.

Powersport loans are assessed for credit quality based upon the FICO score of the borrowers at origination in addition to the contractual aging status of the loan and payment activity. Such assessment is completed at the end of each reporting period.

**Note 1. Summary of Significant Accounting Policies (continued)**

On an annual basis, an independent loan review is completed on a sample of commercial and industrial, commercial real estate and construction and development loans. The reviews are completed in enough detail to, at a minimum, validate the risk rating. Additionally, the reviews determine whether any documentation exceptions exist, appropriate written analysis is included in the loan file, and whether credit policies have been properly adhered to.

Annually, an independent review is also conducted for a sample of residential real estate, home equity loans and lines of credit, powersport, and installment and other loans in order to assess underwriting quality and adherence to policy.

**Unfunded commitment reserve:** The unfunded commitment reserve represents the expected credit losses on off-balance sheet commitments such as unfunded commitments to extend credit and standby letters of credit. However, a liability is not recognized for commitments that are unconditionally cancellable by the Company. The unfunded commitment reserve is recognized as a liability and included in other liabilities on the consolidated balance sheets, with adjustments to the unfunded commitment reserve recognized as a provision for credit loss expense in the consolidated statements of income. The unfunded commitment reserve is determined by estimating expected future fundings, under each segment, and applying the expected loss rates. Expected future fundings are based on historical averages of the likelihood of draws on outstanding commitments. The unfunded commitment reserve was $7,000 at both June 30, 2025 and December 31, 2024.

**Repossessed assets:** Repossessed assets include assets that have been recorded in satisfaction of debt and are initially recorded at fair value less estimated costs to sell, establishing a new cost basis. Subsequently, valuations are periodically performed by management and the assets are carried at lower of carrying amount or fair value less cost to sell. Unrealized losses and operating results from foreclosed and repossessed assets are shown in noninterest expenses on the consolidated statements of income.

**Premises and equipment:** Premises and equipment are stated at cost less accumulated depreciation. Depreciation is calculated using the straight-line method for buildings, furniture and equipment based on estimated useful lives of the assets. Leasehold improvements are depreciated over the term of the lease, including renewal options.

**Leases:** Right-of-use assets and lease liability amounts are determined based on the present value of remaining minimum lease payments, discounted using the Company's incremental borrowing rate for the remaining life of the lease as of the date of adoption or at lease inception.

**Bank owned life insurance:** Bank owned life insurance is recorded at its cash surrender value, which is the estimated realizable value. The change in net asset value along with death benefit income, if any, is shown on the consolidated statements of income as income from bank owned life insurance.

**Transfers of financial assets:** Transfers of financial assets are accounted for as sales only when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

**Note 1. Summary of Significant Accounting Policies (continued)**

**Revenue recognition:** The Company completed its overall assessment of revenue streams and related contracts included in the guidance, including customer service fees, net gain or loss on sale of repossessed assets, and other non-interest related fees.

● *Customer service fees –* Revenue from service charges on deposit accounts is earned through deposit-related services; overdraft, non-sufficient funds, account analysis and other deposit- related fees. Revenue is recognized for these services either over time, corresponding with deposit accounts' monthly cycles, or at a point in time for transaction related services and fees.

● *Net gain or loss on sale of repossessed assets –* Gain or loss from the sale of repossessed assets is recorded when control of the property transfers to the buyer at the time of the auction or sale. The Company does not finance the sale of repossessed powersport assets.

● *Other –* Revenue from these transaction-based fees are recognized at the point in time the transaction is executed.

**Income taxes:** Deferred taxes are provided using the liability method. Deferred tax assets are recognized for deductible temporary differences and operating loss and tax credit carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amounts of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Deferred tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment. The Company shows net deferred taxes in the accompanying consolidated balance sheets.

The Company recognizes tax liabilities when the Company believes that certain positions may not be fully sustained upon review by tax authorities. Benefits from tax positions are measured at the largest amount of benefit that is greater than 50% likely of being realized upon settlement. To the extent that the final outcome of a tax matter is different than the amount recorded, such difference impacts income tax expense in the period such determination is made. The Company did not have any material uncertain tax positions as of June 30, 2025 or December 31, 2024.

The Company would recognize interest and penalties on income taxes as a component of income tax expense.

The Company is generally no longer subject to U.S. federal or state and local income tax examinations by tax authorities for years before 2021.

**Stock-based compensation:** The Company estimates the fair value of stock-based awards on the date of grant. The value of the portion of the award that is ultimately expected to vest is recognized as expense in the Company's consolidated statements of income over the requisite service periods. Compensation expense for stock-based awards is recognized using straight-line vesting for restricted shares.

Because stock-based compensation expense is based on awards that are ultimately expected to vest, stock-based compensation expense may be reduced to account for estimated forfeitures. The Company estimates forfeitures at the time of grant and revises them, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

**Note 1. Summary of Significant Accounting Policies (continued)**

**Comprehensive income:** Comprehensive income consists of net income and other comprehensive income (loss). Certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, net of deferred taxes, are reported as a separate component of the stockholders' equity section of the consolidated balance sheets and are components of comprehensive income.

**Reclassifications:** Certain amounts in the 2024 consolidated financial statements have been reclassified to conform to the 2025 presentation with no effect on net income or stockholders' equity.

**Subsequent events:** On July 1, 2025, Old Second Bancorp, Inc. ("***Old Second***") completed its previously announced merger (the "***Merger***") with Bancorp Financial, Inc. ("***Bancorp Financial***"), pursuant to the Agreement and Plan of Merger dated as of February 24, 2025 (the "***Merger Agreement***"). At the effective time of the Merger (the "***Effective Time***"), Bancorp Financial merged with and into Old Second, with Old Second surviving the Merger. Immediately following the Merger, Evergreen Bank Group, an Illinois-chartered banking corporation and wholly-owned subsidiary of Bancorp Financial, merged with and into Old Second National Bank ("***OSNB***"), a national banking association and wholly- owned subsidiary of Old Second, with the OSNB continuing as the surviving bank.

Pursuant to the terms of the Merger Agreement, at the Effective Time, each Bancorp Financial stockholder became entitled to receive, for each share of Bancorp Financial common stock held, 2.5814 shares of Old Second common stock and $15.93 in cash, without interest, with cash paid in lieu of any fractional shares. Each outstanding share of Old Second's common stock remained outstanding and was unaffected by the Merger.

On June 30, 2025 and immediately prior to closing the acquisition, the vesting of 324,916 restricted stock units was accelerated as a result of the acquisition triggering the change in control agreements for certain individuals and resulted in $4,562,081 of compensation and related taxes expense. The accelerated vesting was approved by the board of directors and legal counsel due to the acquisition being substantially completed at the time.

At June 30, 2025, there were a total of 133 securities in an unrealized loss position with a total of 10.3% depreciation. At December 31, 2024, there were a total of 136 securities in an unrealized loss position with a total of 10.8% depreciation.

Unrealized losses were related to changes in market interest rates and market conditions that do not represent credit-related impairments. The Company does not intend to sell securities that are in an unrealized loss position, and it is more likely than not that the Company will recover the amortized cost prior to being required to sell the debt securities. Full collection of the amounts due according to the contractual terms of the debt securities is expected; therefore, no ACL was recorded in relation to debt securities, and the impairment related to noncredit factors is recognized in OCI, net of applicable taxes.

The amortized cost and fair value of debt securities as of June 30, 2025, by contractual maturity are shown below. Expected maturities of residential mortgage-backed securities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Therefore, these securities are not included in the maturity categories in the following maturity summary.

Estimated interest income that would have been recognized if loans on nonaccrual status had been current in accordance with their original terms for the six months ended June 30, 2025 and 2024 was $79,374 and $141,422, respectively.

Management's evaluation as to the ultimate collectability of nonaccrual loans includes estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. These estimates are affected by changing economic conditions and the economic prospects of borrowers. Collateral dependent loans are loans in which repayment is expected to be provided solely by the underlying collateral and there are no other available and reliable sources of repayment. Loans are written down to the lower of cost or fair value of underlying collateral, less estimated costs to sell. The following tables present collateral dependent loans as of June 30, 2025 and December 31, 2024:

For commercial loans, the Company's credit quality indicator is internally assigned risk ratings. Each commercial loan is assigned a risk rating upon origination. Consumer loans, excluding powersport loans, are assigned a risk rating once a loan is added to the watch list. The risk rating is reviewed on a periodic basis depending on the specific circumstances of the loan.

The following tables present the risk categories of loans evaluated by segment of loans based on the most recent analysis performed and the contractual aging as of June 30, 2025 and December 31, 2024:

#### Note 6. Commitments, Contingencies and Credit Risk
**Financial instruments with off-balance-sheet risk:** The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments are limited to commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets.

The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. A summary of the Company's commitments is as follows:

---

| | | |
|:---|:---|:---|
|  | **June 30,**<br>**2025** | **December 31,**<br>**2024** |
| Commitments to extend credit | $157504637 | $149233572 |
| Letters of credit | 148125 | 479170 |
|  | $157652762 | $149712742 |

---

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer's creditworthiness and determines the amount of collateral required based on management's credit evaluation of the counterparty.

Letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements and, generally, have terms of one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company holds collateral, which may include accounts receivable, inventory, property and equipment, income producing properties, supporting those commitments if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount shown in the summary above. If the commitment is funded, the Company would be entitled to seek recovery from the customer. At June 30, 2025 and December 31, 2024, no amounts have been recorded as liabilities for the Company's potential obligations under these guarantees.

Collateral held for both commitments to extend credit and letters of credit varies but may include securities, accounts receivable, inventories, property and equipment, and income-producing commercial properties.

**Contingencies:** Due to the nature of its business activities, the Company is subject to pending and threatened legal action which arises in the normal course of business. In the opinion of management, after considering the advice of its legal counsel, there is no pending or threatened legal action of any material consequence at June 30, 2025 and December 31, 2024.

**Concentrations of credit risk:** In addition to financial instruments with off-balance-sheet risk, the Company, to a certain extent, may be exposed to varying risks associated with concentrations of credit. Concentrations of credit risk generally exists if a number of counterparties are engaged in similar activities and have similar economic characteristics that would cause their ability to meet contractual obligations to be similarly affected by economic or other conditions.

**Note 6. Commitments, Contingencies and Credit Risk (continued)**

The nature of the Company's business requires that it maintain amounts due from banks and federal funds sold which, at times, may exceed federally insured limits. Management monitors these correspondent relationships and the Company has not experienced any losses in such accounts.

#### Note 7. Dividend Restrictions and Regulatory Capital Requirements
Bank regulations place restrictions upon the amount of dividends that can be paid to the Company by its subsidiary bank. The availability of dividends may be further limited because of the need to maintain capital ratios satisfactory to applicable regulatory agencies.

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by regulators that, if undertaken, could have a direct material effect on the financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices.

The capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the following tables) of total, Tier 1 and Common Equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier 1 capital to average assets. Management believes the Bank meets all capital adequacy requirements to which it is subject as of June 30, 2025.

As of June 30, 2025, the most recent notification from the Federal Deposit Insurance Corporation categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based, Tier 1 Common Equity, and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank's categories.

#### Note 8. Fair Value Measurements
The Company applies the accounting standard, *Fair Value Measurements and Disclosures* (the Standard), for assets and liabilities measured and reported at fair value. The Standard defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The Standard requires the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach in the determination of fair value. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable, meaning those that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources, or unobservable, meaning those that reflect the reporting entity's own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, the Standard establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs.

The fair value hierarchy is as follows:

<u>Level 1</u>: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

<u>Level 2</u>: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

<u>Level 3</u>: Significant unobservable inputs that reflect a reporting entity's own assumptions about the assumptions that market participants would use in pricing an asset or liability.

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

---

**Securities available for sale:** When available, quoted market prices are used to determine the fair value of investment securities and such items are classified within Level 1 of the fair value hierarchy. For other securities, the Company determines fair value based on various sources and may apply matrix pricing with observable prices for similar bonds where a price for the identical bond is not observable. Securities measured at fair value by such methods are classified as Level 2. During the six months ended June 30, 2025 and year ended December 31, 2024, there were no transfers between levels.

**Loans individually evaluated for credit loss:** The Company does not record loans at fair value on a recurring basis. However, periodically, a loan is evaluated individually and is reported at the lower of cost or fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the collateral value is not sufficient, a specific reserve is recorded. Collateral values are estimated using a combination of observable inputs, including recent appraisals, and unobservable inputs based on customized discounting criteria. Due to the significance of unobservable inputs, fair values of individually evaluated collateral dependent loans have been classified as Level 3.

**Repossessed assets:** Repossessed assets are carried at the estimated fair value of the asset, less disposal costs. The fair value of the asset is determined based upon appraisals. As with individually evaluated loans, if significant adjustments are made to the appraised value, based upon unobservable inputs, the resulting fair value measurement is categorized as a Level 3 measurement.

**UNAUDITED PRO FORMA<br>CONDENSED COMBINED CONSOLIDATED FINANCIAL INFORMATION**

The following tables show the condensed combined financial information for each of Old Second Bancorp, Inc. ("Old Second") and Bancorp Financial, Inc. ("Bancorp Financial"), as well as unaudited pro forma condensed combined financial information for Old Second and Bancorp Financial reflecting the merger as of and for the six months ended June 30, 2025, and pro forma adjustments described in the accompanying notes.

Except as otherwise noted in the footnotes to the tables, (a) the financial information included under the "Historical OSBC" column is derived from and should be read in conjunction with Old Second's historical unaudited interim condensed financial statements and accompanying notes included in Old Second's Quarterly Report on Form 10-Q for the period ended June 30, 2025, and (b) the financial information under the "Historical Bancorp Fin" column is derived from and should be read in conjunction with Bancorp Financial's historical unaudited condensed financial statements and accompanying notes for the period ended June 30, 2025, which are filed as Exhibit 99.2 to Old Second's Amendment to the Current Report on Form 8-K filed on September 17, 2025.

The unaudited pro forma condensed combined financial information has been prepared to give effect to the following:

● The acquisition of Bancorp Financial by Old Second under the provision of Financial Accounting Standard Board (FASB) Accounting Standards Codification, ASC 805, "Business Combinations" where the sale of assets and liability of Bancorp Financial will be recorded by Old Second at their respective fair values as of the date the merger is completed ;

● The distribution of shares of Old Second common stock to Bancorp Financial shareholders in exchange for shares of Bancorp Financial common stock (based on a 2.5814 exchange ratio) and $15.93 in cash per share, without interest;

● Certain reclassifications to conform the historical Bancorp Financial financial information presentation to Old Second; and

● Transaction costs in connection with the merger.

The accompanying unaudited pro forma condensed combined balance sheet as of June 30, 2025 combines the historical consolidated balance sheets of Old Second and Bancorp Financial, presenting the merger as if it had been consummated on June 30, 2025. The unaudited pro forma condensed combined income statements for the six months ended June 30, 2025, combine the historical consolidated income statements of Old Second and Bancorp Financial, presenting the merger as if it had been consummated on January 1, 2025. You should read the accompanying Notes to the Unaudited Pro Forma Condensed Combined Balance Sheet and Income Statements.

The unaudited pro forma combined condensed consolidated financial information is presented for illustrative purposes only, and does not necessarily indicate the financial results of the combined company had Old Second and Bancorp Financial actually been combined as of the dates indicated and at the beginning of the periods presented, nor does it necessarily indicate the results of operations in future periods of the future financial position of the combined entities, which could differ materially from those shown in this information. The unaudited pro forma condensed combined financial information does not reflect the benefits of expected synergies, anticipated cost savings, or other factors that may result as a consequence of the merger. The unaudited pro forma condensed combined financial information also does not consider any potential effect of changes in market conditions or interest rates on revenues or the impact of changes in Old Second's stock price. As explained in more detail in the accompanying notes, the preliminary allocation of the pro forma purchase price reflected in the pro forma condensed combined financial information is subject to adjustment and may vary significantly from the actual purchase price allocation that will be recorded upon completion of the merger, as final valuations are known. The preliminary pro forma adjustments have been presented solely for the purpose of providing the unaudited pro forma condensed combined financial information.

As of the date of this pro forma financial information, Old Second has not yet finalized the valuation analysis and calculations at the level of detail required to obtain the necessary estimates of the fair market values of the Bancorp Financial assets to be acquired or liabilities to be assumed, other than a preliminary estimate for intangible assets and certain financial assets and liabilities. Therefore, certain Bancorp Financial assets and liabilities are presented at their respective carrying amounts and should be considered preliminary values. A final determination of the fair values of Bancorp Financial's assets and liabilities will be obtained based on the final valuation of Bancorp Financial's actual asset and liabilities as of the closing date. Actual adjustments may differ from the amounts reflected in the unaudited pro forma condensed combined financial information, and the differences may be material. Any changes in the fair values of the net assets or total purchase consideration as compared with the information shown in the unaudited pro forma condensed combined financial information may change the amount of the total purchase consideration allocated to goodwill, deferred taxes and other assets and liabilities and may impact the combined company's statement of income.

**NOTES TO THE UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION**

**Note 1: Basis of Presentation**

The pro forma condensed combined financial information and explanatory notes have been prepared to illustrate the effects of the merger under the acquisition method of accounting with Old Second as the acquirer. The pro forma condensed combined financial information is presented for illustrative purposes only and does not necessarily indicate the financial condition or results of the combined companies had the companies actually been combined at the beginning of the periods presented, nor does it necessarily indicate the results of operations in future periods or the future financial position of the combined company. Under the acquisition method of accounting, the assets and liabilities of Bancorp Financial, as of the effective date of the merger, will be recorded by Old Second at their respective fair values and the excess of the merger consideration over the fair value of Bancorp Financial's net assets will be allocated to goodwill.

The merger provides that Bancorp Financial shareholders will receive (a) $15.93 cash consideration for each share of Bancorp Financial common stock they hold immediately prior to the merger, and (b) 2.5814 shares of Old Second common stock for each share of Bancorp Financial common stock they hold immediately prior to the merger. The implied value of the merger consideration to Bancorp Financial shareholders is $45.79 per share, or a total of $140.5 million, based on the closing stock price of Old Second common stock of $17.74 per share as of June 30, 2025, which is the price effective at the time of the merger.

The pro forma allocation of the purchase price presented in the pro forma condensed combined financial information is subject to adjustment and may vary from the actual purchase price allocation that will be recorded at the time the merger valuations are finalized. Adjustments may include, but are not limited to, changes in (a) total merger related expenses and implementation costs, which may vary from currently estimated amounts included herein; and (b) the underlying values of assets and liabilities if market and credit conditions differ from current assumptions.

**Note 2: Preliminary Purchase Price**

The pro forma adjustments include the estimated purchase accounting entries to record the merger transaction. The excess of the purchase price over the fair value of net assets acquired, net of deferred taxes, is allocated to goodwill. Estimated fair value adjustments included in the pro forma condensed combined financial statement are based upon available information and certain assumptions considered reasonable, and may be revised as additional information becomes available.

The following table summarizes the determination of the purchase price consideration from the June 30, 2025, baseline price, and its impact on the preliminary goodwill estimate.

**Note 3: Pro Forma Adjustments to Unaudited Condensed Combined Financial Information**

The following pro forma adjustments have been reflected in the unaudited pro forma condensed combined financial information. All adjustments are based on preliminary assumptions and valuations, which are subject to change.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) Adjustments to cash to reflect the estimated cash components of the merger consideration of $48.9 million, based on 3,068,566 shares of Bancorp Financial common stock outstanding as of June 30, 2025, and an adjustment of $8.0 million to payoff Bancorp Financial debt. Purchase accounting adjustments to cash include a $6.0 million reduction due to after tax acquisition costs. Cash inflows are also impacted by the net proceeds on the sale of Bancorp Financial's available for sale securities of $117.6 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) Adjustment to Bancorp Financial specific to the sale of $117.6 million of available for sale securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) Adjustment to Bancorp Financial loans reflects estimated fair value adjustments, which include the adjustment for the credit component of the loan portfolio, the purchased credit deteriorated ("PCD") loan CECL gross up, adjustments related to current interest rates and liquidity, and adjustments attributable to the reversal of the prior unearned loan fees and costs recorded by Bancorp Financial.
