Note 1: Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information or footnotes necessary for a complete presentation of financial condition, results of operations, changes in shareholders’ equity, or cash flows in accordance with GAAP. In our opinion, all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation have been included. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results expected for the year ending December 31, 2026 or any other period. The March 31, 2026 condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in the First Internet Bancorp Annual Report on Form 10-K for the year ended December 31, 2025.

The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments, or assumptions that could have a material effect on the carrying value of certain assets and liabilities. These estimates, judgments, and assumptions affect the amounts reported in the condensed consolidated financial statements and the disclosures provided. The Company utilizes processes that involve the use of significant estimates and the judgment of management in determining the amount of the Company’s allowance for credit losses (“ACL”) and changes in any of these could have a significant impact on the condensed consolidated financial statements.

The condensed consolidated financial statements include the accounts of First Internet Bancorp (the “Company”), its wholly owned subsidiary, First Internet Bank of Indiana (the “Bank”), and the Bank’sthree wholly owned subsidiaries, First Internet Public Finance Corp., JKH Realty Services, LLC and SPF15, Inc. All significant intercompany accounts and transactions have been eliminated in consolidation.

The Company is subject to claims and lawsuits that arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material adverse effect on the consolidated financial position, results of operations, and cash flows of the Company.

Note 2: Earnings Per Share

Earnings per share of common stock are based on the weighted-average number of basic shares and dilutive shares outstanding during the period.

The following is a reconciliation of the weighted-average common shares for the basic and diluted earnings per share computations for the three months ended March 31, 2026 and 2025.

1 Potential dilutive common shares are excluded from the computation of diluted EPS in the periods where the effect would be antidilutive. There were 11,186 and 3,916 weighted-average antidilutive shares excluded from the computation of diluted EPS for the three months ended March 31, 2026 and 2025, respectively.

Note 3: Securities

The following tables summarize securities available-for-sale (“AFS”) and securities held-to-maturity (“HTM”) as of March 31, 2026 and December 31, 2025.

1 Includes $0.2 million of additional premium related to terminated interest rate swaps associated with agency mortgage-backed securities - residential as of March 31, 2026.

1 Includes $0.2 million of additional premium related to terminated interest rate swaps associated with agency mortgage-backed securities - residential as of December 31, 2025.

Accrued interest receivable on AFS and HTM securities at March 31, 2026 was $2.9 million and $1.0 million, respectively, compared to $3.0 million and $1.1 million, respectively, at December 31, 2025, and is included in accrued interest receivable on the condensed consolidated balance sheet. The Company elected to exclude all accrued interest receivable from securities when estimating credit losses.

At March 31, 2026 and December 31, 2025, approximately 86% and 84%, respectively, of mortgage-backed securities (including both AFS and HTM) held by the Company are issued by U.S. government-sponsored entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government and have a long history of no credit losses; therefore, the Company did not record an ACL on these securities.

Additionally, the Company evaluated credit impairment for individual AFS securities that are in an unrealized loss position and determined that the unrealized losses are unrelated to credit quality and are primarily attributable to changes in interest rates and volatility in the financial markets. As the Company does not intend to sell the AFS securities that are in an unrealized loss position, and it is unlikely that it will be required to sell these securities before recovery of their amortized cost basis, the Company did not record an ACL on these securities.

The Company also evaluated its HTM securities that are in an unrealized loss position and considered issuer bond ratings, historical loss rates for bond ratings and economic forecasts. The ACL on HTM securities was $0.1 million at both March 31, 2026 and December 31, 2025.

The carrying value of securities at March 31, 2026 is shown below by their contractual maturity date. Actual maturities will differ because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

No AFS securities were sold during the three months ended March 31, 2026 and March 31, 2025. As such, the Company did not realize any gains or losses related to the sale of AFS securities during either time period.

Certain investments in debt securities are reported in the condensed consolidated financial statements at an amount less than their historical cost. The total fair value of these investments at March 31, 2026 and December 31, 2025 was $633.1 million and $611.2 million, which was approximately 60% and 59%, respectively, of the Company’s AFS and HTM securities portfolios. As of March 31, 2026, the Company’s security portfolio consisted of 623 positions, of which 412 were in an unrealized loss position. As of December 31, 2025, the Company’s security portfolio consisted of 618 positions, of which 395 were in an unrealized loss position. The unrealized losses are related to the categories noted below.

U. S. Government-Sponsored Agencies, Municipal Securities and Corporate Securities

The unrealized losses on the Company’s investments in securities issued by U.S. Government-sponsored agencies, municipal organizations and corporate entities were caused primarily by interest rate changes. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. The Company does not intend to sell the investments, and it is not more likely than not that the Company will be required to sell the investments, before recovery of their amortized cost basis, which may be upon maturity.

Agency Mortgage-Backed, Private Label Mortgage-Backed Securities and Asset-Backed Securities

The unrealized losses on the Company’s investments in agency mortgage-backed, private label mortgage-backed securities and asset-backed securities were caused primarily by interest rate changes. The Company expects to recover the amortized cost basis over the terms of the securities. The Company does not intend to sell the investments, and it is not more likely than not that the Company will be required to sell the investments, before recovery of their amortized cost basis, which may be upon maturity.

The following tables show the securities portfolio’s gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at March 31, 2026 and December 31, 2025.

The following tables summarize ratings for the Company’s HTM portfolio as of March 31, 2026 and December 31, 2025.

1 This security previously had a BBB rating, but the issuer was acquired during the first quarter 2026. The acquiring company did not have any outstanding subordinated debt issuances prior to the acquisition and, therefore, did not have a rating at the time of acquisition.

Equity Investments

Equity investments, largely comprised of non-marketable equity investments, are generally accounted for under equity security accounting and are included within accrued income and other assets on the consolidated balance sheet. The Company’s non-marketable equity investments consist of limited partner interests in venture capital and Small Business Investment Company (“SBIC”) funds. After the initial commitment and over the course of the investment period, the Company will make capital contributions and receive a proportional share of profit and return of capital distributions as a result of fund performance until the funds wind down. While the partnership agreements allow the Company to remove the general partner, this right is not considered to be substantive as the general partner can only be removed for cause. All of these investments are generally non-redeemable and distributions are generally expected to be received through the liquidation of the underlying investments throughout the life of the investment fund. Investments may only be sold or transferred subject to the notice and approval provisions of the underlying investment agreements.

The following tables provide additional information related to equity investments accounted for under equity security accounting.

The carrying amount of each equity investment with a readily determinable fair value or net asset value at March 31, 2026 and December 31, 2025 is reflected in the following table:

The carrying amount of the Company’s investments in non-marketable equity securities with no readily determinable fair value and amounts recognized in earnings on a cumulative basis at March 31, 2026 and December 31, 2025 is reflected in the following table:

1 Excludes $14.3 million and $14.6 million in unfunded commitments as of March 31, 2026 and December 31, 2025, respectively.

Variable Interest Entities

The above investments meet the criteria of a VIE. However, the Company is not the primary beneficiary of the entities as it does not have the power to direct the activities that most significantly impact the economic performance of the entities. The Company’s maximum exposure to loss from unconsolidated VIEs includes the value of the investment recorded on the Company’s consolidated balance sheets and unfunded commitment. The Company believes the potential for loss from these investments is remote, the maximum exposure for the affordable housing investment was determined by assuming a scenario where related tax credits were recaptured.

The following table provides a summary of VIEs that the Company has not consolidated as March 31, 2026 and December 31, 2025:

(1) Maximum exposure to loss includes $13.4 million of current investments and $6.0 million in unfunded commitments.

(2) Maximum exposure to loss includes $2.9 million of current investments.

(3) Maximum exposure to loss includes $7.3 million of current investments and $5.7 million in unfunded commitments.

(4) Maximum exposure to loss includes $7.4 million of current investments, $2.6 million in unfunded commitments and a scenario in which related tax credits of $2.5 million are recaptured, totaling $12.5 million.

(5) Maximum exposure to loss includes $10.0 million of current investments.

(6) Maximum exposure to loss includes $13.7 million of current investments and $6.0 million in unfunded commitments.

(7) Maximum exposure to loss includes $2.9 million of current investments.

(8) Maximum exposure to loss includes $7.3 million of current investments and $5.7 million in unfunded commitments.

(9) Maximum exposure to loss includes $7.6 million of current investments, $2.6 million in unfunded commitments and a scenario in which related tax credits of $2.5 million are recaptured, totaling $12.5 million.

(10) Maximum exposure to loss includes $10.0 million of current investments.

Note 4: Loans

Loan balances as of March 31, 2026 and December 31, 2025 are summarized in the table below. Categories of loans include:

1 Balances include $59.5 million and $52.2 million that are guaranteed by the U.S. government as of March 31, 2026 and December 31, 2025, respectively.

2 Includes carrying value adjustment of $18.1 million and $19.1 million related to terminated interest rate swaps associated with public finance loans as of March 31, 2026 and December 31, 2025, respectively.

The general risk characteristics specific to each loan portfolio segment are as follows:

Commercial and Industrial: Commercial and industrial loans’ sources of repayment are primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected, and the collateral securing these loans may fluctuate in value. Loans are made for working capital, equipment purchases, or other purposes. Most commercial and industrial loans are secured by the assets being financed and may incorporate a personal guarantee. This portfolio segment is generally concentrated in the Midwest and Southwest regions of the United States.

Owner-Occupied Commercial Real Estate: The primary source of repayment is the cash flow from the ongoing operations and activities conducted by the borrower, or an affiliate of the borrower, who owns the property. This portfolio segment is generally concentrated in the Midwest and Southwest regions of the United States and its loans are often secured by manufacturing and service facilities.

Investor Commercial Real Estate: These loans are made on a nationwide basis and are underwritten primarily based on the cash flow expected to be generated from the property and are secondarily supported by the value of the real estate. These loans typically incorporate a personal guarantee from the primary sponsor or sponsors. This portfolio segment generally involves larger loan amounts with repayment primarily dependent on the successful leasing and operation of the property securing the loan or the business conducted on the property securing the loan. Investor commercial real estate loans may be more adversely affected by changing economic conditions in the real estate markets, industry dynamics or the overall health of the local economy where the property is located. The properties securing the Company’s investor commercial real estate portfolio tend to be diverse in terms of property type. Management monitors and evaluates commercial real estate loans based on property financial performance, collateral value, guarantor strength, economic and industry conditions together with other risk grade criteria. As a general rule, the Company avoids financing special use projects unless other underwriting factors are present to mitigate these additional risks.

Construction: Construction loans are made on a nationwide basis and are secured by land and related improvements and are made to assist in the construction of new structures, which may include commercial (retail, industrial, office, and multi-family) properties, land development for residential properties or single family residential properties offered for sale by the builder. These loans generally finance a variety of project costs, including land, site preparation, architectural services, construction, closing and soft costs and interim financing needs. The cash flows of builders, while initially predictable, may fluctuate with market conditions, and the value of the collateral securing these loans may be subject to fluctuations based on general economic changes.

Single Tenant Lease Financing: These loans are made on a nationwide basis to owners of real estate subject to long-term lease arrangements with single tenant operators. The real estate is typically operated by regionally, nationally or globally branded businesses. The loans are underwritten based on the financial strength of the borrower, characteristics of the real estate, cash flows generated from the lease arrangements and the financial strength of the tenant. Similar to the other loan portfolio segments, management monitors and evaluates these loans based on borrower and tenant financial performance, collateral value, industry trends and other risk grade criteria.

Public Finance: These loans are made on a nationwide basis to governmental and not-for-profit entities to provide both tax-exempt and taxable loans for a variety of purposes including: short-term cash-flow needs; debt refinancing; economic development; quality of life projects; infrastructure improvements; renewable energy projects; and equipment financing. The primary sources of repayment for public finance loans include pledged revenue sources including but not limited to: general obligations; property taxes; income taxes; tax increment revenue; utility revenue; gaming revenues; sales tax; and pledged general revenue. Certain loans may also include an additional collateral pledge of mortgaged property or a security interest in financed equipment.

Healthcare Finance: These loans are made on a nationwide basis to healthcare providers, primarily dentists, for practice acquisition financing or refinancing that occasionally includes owner-occupied commercial real estate and equipment purchases. The sources of repayment are primarily based on the identified cash flows from operations of the borrower and related entities and secondarily on the underlying collateral provided by the borrower.

Small Business Lending: These loans are made on a nationwide basis to small businesses and generally carry a partial guaranty from the U.S. Small Business Administration (“SBA”) under its 7(a) loan program. We generally sell the government guaranteed portion of SBA loans into the secondary market while retaining the non-guaranteed portion of the loan and the servicing rights. Loans in the small business lending portfolio have sources of repayment that are primarily based on the identified cash flows of the borrower and secondarily on any underlying collateral provided by the borrower. Loans may, but do not always, have a collateral shortfall. For SBA loans where the guaranteed portion is retained, the SBA guaranty provides a tertiary source of repayment to the Bank in the event of borrower default. Cash flows of borrowers, however, may not be as expected and collateral securing these loans may fluctuate in value. Loans are made for a broad array of purposes including, but not limited to, providing operating cash flow, funding ownership changes, and facilitating equipment and commercial real estate purchases.

Franchise Finance: These loans are made on a nationwide basis with financing options for new franchise units, recapitalization, expansion, equipment and working capital. The sources of repayment are either based on identified cash flows from existing operations of the borrower or pro forma cash flow for new franchise locations.

Residential Mortgage: With respect to residential loans that are secured by 1-to-4 family residences and are generally owner occupied, the Company typically establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Repayment of these loans is primarily dependent on the financial circumstances of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Repayment can also be impacted by changes in residential property values. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers in geographically diverse locations throughout the country.

Home Equity: Home equity loans and lines of credit are typically secured by a subordinate interest in 1-to-4 family residences. Repayment of these loans and lines of credit is primarily dependent on the financial circumstances of the borrowers and may be impacted by changes in unemployment levels and property values on residential properties, among other economic conditions in the market. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers in geographically diverse locations throughout the country.

Other Consumer: These loans primarily consist of consumer loans and credit cards. Consumer loans may be secured by consumer assets such as horse trailers or recreational vehicles. Some consumer loans are unsecured, such as small installment loans, home improvement loans and certain lines of credit. Repayment of consumer loans is primarily dependent upon the personal income of the borrowers, which can be impacted by economic conditions in their market areas such as unemployment levels. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers in geographically diverse locations throughout the country.

ACL Methodology

The ACL for loans represents management's estimate of all expected credit losses over the expected life of the Company’s existing loan portfolio. Management estimates the ACL balance using relevant available information about the collectability of cash flows, from internal and external sources, including historical information relating to past events, current conditions, and reasonable and supportable forecasts of future economic conditions. When the Company is unable to forecast future economic events, management may revert to historical information.

The Company's methodologies incorporate a one-year reasonable and supportable forecast period with a one-year straight line reversion to the long-term historical average for most segments.

The ACL methodology may also consider other adjustments to address changes in conditions, trends, and circumstances such as local industry changes that could have a significant impact on the risk profile of the loan portfolio and provide for adjustments that may not be reflected and/or captured in the historical loss data. These factors include: lending policies, imprecision in forecasting future economic conditions, loan profile, lending staff, problem loan trends, loan review, collateral, credit concentration, or other internal and external factors. The Company includes these as qualitative adjustments to the ACL which include, but are not limited to:

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

•Changes in international, national, regional and local economic conditions

•Changes in the nature and volume of the portfolio and terms of loans

•Changes in the experience, depth and ability of lending management

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

•Changes in the quality of the Company’s loan review system

•Changes in the value of underlying collateral for collateral dependent loans

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

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

The ACL is measured on a collective or pool basis when similar risk characteristics exist. The Company segments its portfolio generally by Federal Financial Institutions Examination Council ("FFIEC") Call Report codes that align with its lines of business. Additional sub-segmentation has not been utilized to identify groups of loans with unique risk characteristics relative to the rest of the portfolio.

Loans that do not share similar risk characteristics are evaluated on an individual basis. These evaluations are typically performed on loans with a deteriorated internal risk rating. The ACL is determined based on several methods, including estimating the fair value of the underlying collateral or the present value of expected cash flows.

Modified Loans to Borrowers Experiencing Financial Difficulty

The Company may make modifications to certain loans in order to alleviate temporary difficulties in the borrower’s financial condition and/or constraints on the borrower’s ability to repay the loan, and to minimize potential losses to the Company. Modifications may include changes in the amortization terms of the loan, other-than-insignificant payment delays, reductions in interest rates, acceptance of interest only payments, and/or reductions to the outstanding loan balance. Such loans may be placed on nonaccrual status when there is doubt concerning the full repayment of principal and interest or the loan has been delinquent for a period of 90 days or more. These loans may be returned to accrual status when all contractual amounts past due have been brought current, and the borrower’s performance under the modified terms of the loan agreement and the ultimate collectability of all contractual amounts due under the modified terms is no longer in doubt. The Company typically measures the ACL on modified loans to borrowers experiencing financial difficulty on an individual basis when the loans are deemed to no longer share risk characteristics that are similar with other loans in the portfolio. The calculation of the ACL for these loans is based on a discounted cash flow approach for both those measured collectively and individually, unless the loan is deemed collateral dependent, which requires measurement of the ACL based on the estimated expected fair value of the underlying collateral, less costs to sell. GAAP requires the Company to make certain disclosures related to these loans, including certain types of modifications, as well as how such loans have performed since their modifications.

Provision for Credit Losses

A provision for estimated losses on loans is charged to income based upon management’s evaluation of the potential losses. Such an evaluation, which includes a review of all loans for which full repayment may not be reasonably assured, considers, among other matters, the estimated net realizable value of the underlying collateral, as applicable, economic conditions, loan loss experience, and other factors that are particularly susceptible to changes that could result in a material adjustment in the near term. While management attempts to use the best information available in making its evaluations, future ACL adjustments may be necessary if conditions change substantially from the assumptions used in making the evaluations.

Policy for Charging Off Loans

The Company’s policy is to charge off a loan at any point in time when it no longer can be considered a bankable asset, meaning collectible within the parameters of policy. Commercial loans are generally charged off when management determines they are uncollectible. Consumer loans are generally charged off when they reach a specified level of delinquency, unless they are well secured and in the process of collection.

The following tables present changes in the balance of the ACL during the three months ended March 31, 2026 and 2025.

Accrued interest receivable on loans totaled $23.1 million at both March 31, 2026 and December 31, 2025 and is excluded from the estimate of credit losses. The Company made the accounting policy election to not measure an ACL for accrued interest receivable. Accrued interest deemed uncollectible will be written off through interest income.

In addition to the ACL, the Company maintains a reserve for off-balance sheet commitments, classified in other liabilities. This reserve is at a level management believes to be sufficient to absorb losses arising from unfunded loan commitments. The adequacy of the reserve for unfunded commitments is determined quarterly based on methodology similar to the methodology for determining the ACL. The following tables detail activity in the (benefit) provision for credit losses on off-balance sheet commitments for the three months ended March 31, 2026 and 2025.

The Company utilizes a risk grading matrix to assign a risk grade to each of its commercial loans, which are evaluated annually. A description of the general characteristics of the risk grades is as follows:

•“Pass” - Higher quality loans that do not fit any of the other categories described below.

•“Special Mention” - Loans that possess some potential credit deficiency or weakness, which deserve close attention.

•“Substandard” - Loans that possess a defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Loans that are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any.

•“Doubtful” - Such loans have been placed on nonaccrual status and may be heavily dependent upon collateral possessing a value that is difficult to determine or based upon some near-term event that lacks clear certainty. These loans have all of the weaknesses of those classified as Substandard; however, based on existing conditions, these weaknesses make full collection of the principal balance highly improbable.

The Company does not risk grade its consumer loans. It classifies them as either performing or nonperforming. Below is a description of those classifications:

•“Performing” - Loans that are accruing and full collection of principal and interest is expected.

•“Nonperforming” - Loans that are 90 days delinquent or for which the full collection of principal and interest may be in doubt.

The following tables present the credit risk profile of the Company’s commercial and consumer loan portfolios by loan class and by year of origination for the years indicated based on rating category and payment activity as of March 31, 2026 and December 31, 2025.

The following tables present the Company’s loan portfolio delinquency, including nonperforming loans, as of March 31, 2026 and December 31, 2025.

Loans are reclassified to a non-accruing status when, in management’s judgment, the collateral value and financial condition of the borrower do not justify accruing interest. At the time the accrual is discontinued, all unpaid accrued interest is reversed against earnings. Interest income accrued in prior years, if any, is charged to the allowance for credit losses. Payments subsequently received on nonaccrual loans are applied to principal. A loan is returned to accrual status when principal and interest are no longer past due and collectability is probable, typically after a minimum of nine consecutive months of performance.

The following table summarizes the Company’s nonaccrual loans and loans past due 90 days or more and still accruing by loan class for the periods indicated:

1 Balance includes $15.5 million and $13.6 million at March 31, 2026 and December 31, 2025, respectively, of loans guaranteed by the U.S. government.

Interest income recognized on nonaccrual loans was $0.1 million for both the three months ended March 31, 2026 and 2025.

Determining fair value for collateral dependent loans requires obtaining a current independent appraisal of the collateral and applying a discount factor, which includes selling costs if applicable, to the value. The fair value of real estate is generally based on appraisals by qualified licensed appraisers. The appraisers typically determine the value of the real estate by utilizing an income or market valuation approach. If an appraisal is not available, the fair value may be determined by using a cash flow analysis. Fair value on other collateral such as business assets is typically ascertained by assessing, either singularly or some combination of, asset appraisals, accounts receivable aging reports, inventory listings and/or customer financial statements.

The following tables present the amortized cost basis of collateral dependent loans, which are individually evaluated to determine expected credit losses as of March 31, 2026 and December 31, 2025.

1 Balance includes $8.3 million of loans guaranteed by the U.S. government.

1 Balance includes $8.5 million of loans guaranteed by the U.S. government.

Loan Modifications to Borrowers Experiencing Financial Difficulty

The Company may agree to modify the contractual terms of a loan to a borrower experiencing financial difficulty as a part of ongoing loss mitigation strategies. These modifications may include interest rate reductions, principal or interest forgiveness, other-than-insignificant payment delays, term extensions and other actions intended to minimize loss and to avoid foreclosure or repossession of collateral.

The Company hadone loan modification made to borrowers experiencing financial difficulty during the three months ended March 31, 2026. The Company hadtwo loan modifications made to borrowers experiencing financial difficulty during the three months ended March 31, 2025.

The following tables present loans that were both experiencing financial difficulty and modified during the three months ended March 31, 2026 and 2025.

The Company closely monitors the performance of loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following table presents the performance of loans that were modified within the twelve months ended March 31, 2026.

There were no loans that were modified within the twelve months ended March 31, 2026 that subsequently defaulted during the period presented.

Other Real Estate Owned

The Company had $1.9 million in other real estate owned (“OREO”) as of March 31, 2026, which consisted oftwo small business lending properties. The Company had $2.6 million in OREO as of December 31, 2025, which consisted ofthree small business lending properties. There were eight loans totaling $1.9 million andeight loans totaling $2.5 million, in the process of foreclosure at March 31, 2026 and December 31, 2025, respectively.

Note 5: Premises and Equipment

The following table summarizes premises and equipment at March 31, 2026 and December 31, 2025.

Note 6: Goodwill

As of March 31, 2026 and December 31, 2025, the carrying amount of goodwill was $4.7 million. There have been no changes in the carrying amount of goodwill for the three months ended March 31, 2026 or March 31, 2025. Goodwill is assessed for impairment annually as of August 31, or more frequently if events occur or circumstances change that indicate an impairment may exist. When assessing goodwill for impairment, first, a qualitative assessment can be made to determine whether it is more likely than not that the estimated fair value of a reporting unit is less than its estimated carrying value. If the results of the qualitative assessment are not conclusive, a quantitative goodwill test is performed. Alternatively, a quantitative goodwill test can be performed without performing a qualitative assessment.

Goodwill was assessed for impairment using a quantitative test performed as of August 31, 2025. The estimated fair value of the reporting unit exceeded the net carrying value, and thereforeno goodwill impairment existed as of that date. However, there is a risk for impairment in the event of declines in general economic, market or business conditions and the resultant effect on forecasted growth rates, or any significant unfavorable change in the Company’s forecasted operations resulting from elevated levels of net charge-offs in the franchise finance and small business lending portfolios. If current and long-term projections decrease materially, the Company may be required to recognize impairment charges, which could be material to the results of operations.

Note 7: Servicing Asset

Activity for the servicing asset and the related changes in fair value for the three months ended March 31, 2026 and 2025 are shown in the table below.

Loans serviced for others are not included in the condensed consolidated balance sheets. The unpaid principal balances of these loans serviced for others as of March 31, 2026 and December 31, 2025 are shown in the table below.

Loan servicing revenue totaled $2.9 million and $2.0 million for the three months ended March 31, 2026 and March 31, 2025, respectively. Loan servicing asset revaluation, which represents the change in fair value of the servicing asset, resulted in a $1.1 million and $1.2 million downward valuation for the three months ended March 31, 2026 and March 31, 2025, respectively.

The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Though fluctuations in prepayment speeds and changes in secondary market premiums generally have the most substantial impact on the fair value of servicing rights, other influencing factors include changing economic conditions, changes to the discount rate assumption and the weighted average life of the servicing portfolio. Measurement of fair value is limited to the conditions existing and the assumptions used as of a particular point in time; however, those assumptions may change over time. Refer to Note 11 - Fair Value of Financial Instruments for further details.

Note 8: Subordinated Debt

In June 2019, the Company issued $37.0 million aggregate principal amount of 6.0% Fixed-to-Floating Rate Subordinated Notes due 2029 (the “2029 Notes”) in a public offering. The 2029 Notes bear interest at a floating rate equal to three-month Term SOFR plus 4.376%. All interest on the 2029 Notes is payable quarterly. The 2029 Notes are scheduled to mature on June 30, 2029. The 2029 Notes are unsecured subordinated obligations of the Company and may be repaid at any time, without penalty. The 2029 Notes are intended to qualify as Tier 2 capital under regulatory guidelines.

In October 2020, the Company entered into a term loan in the principal amount of $10.0 million, evidenced by a term note due 2030 (the “2030 Note”). The 2030 Note initially accrued interest at a fixed rate of 6.0% per year to, but excluding, November 1, 2025 and thereafter at a floating rate equal to three-month Term SOFR plus 5.795%. The 2030 Note is an unsecured subordinated obligation of the Company and may be repaid, without penalty, on any interest payment date on or after November 1, 2025. The 2030 Note is intended to qualify as Tier 2 capital under regulatory guidelines. The Company used the net proceeds from the issuance of the 2030 Note to redeem a subordinated term note that had been entered into in October 2015.

In August 2021, the Company issued $60.0 million aggregate principal amount of 3.75% Fixed-to-Floating Rate Subordinated Notes due 2031 (the “2031 Notes”) in a private placement. The 2031 Notes initially bear a fixed interest rate of 3.75% per year to, but excluding, September 1, 2026, and thereafter at a floating rate equal to the then-current benchmark rate (initially three-month Term SOFR) plus 3.11%. The 2031 Notes are scheduled to mature on September 1, 2031. The 2031 Notes are unsecured subordinated obligations of the Company and may be repaid, without penalty, on any interest payment date on or after September 1, 2026. The 2031 Notes are intended to qualify as Tier 2 capital under regulatory guidelines. The Company used a portion of the net proceeds from the issuance of the 2031 Notes to redeem subordinated notes issued by the Company in 2016. Pursuant to the terms of a Registration Rights Agreement between the Company and the initial purchasers of the 2031 Notes, the Company offered to exchange the 2031 Notes for subordinated notes that are registered under the Securities Act of 1933, as amended, and have substantially the same terms as the 2031 Notes. On December 30, 2021, we completed an exchange of $59.3 million principal amount of the unregistered 2031 Notes for registered 2031 Notes in satisfaction of our obligations under the registration rights agreement. Holders of $0.7 million of unregistered 2031 Notes did not participate in the exchange.

The following table presents the principal balance and unamortized discount and debt issuance costs for the 2029 Notes, the 2030 Note, and the 2031 Notes as of March 31, 2026 and December 31, 2025.

Note 10: Commitments and Credit Risk

In the normal course of business, the Company makes various commitments to extend credit which are not reflected in the accompanying condensed consolidated financial statements. At March 31, 2026 and December 31, 2025, the Company had outstanding loan commitments totaling approximately $610.6 million and $617.6 million, respectively.

Note 11: Fair Value of Financial Instruments

ASC Topic 820, Fair Value Measurement, defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC Topic 820 also specifies a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

Level 1 Quoted prices in active markets for identical assets or liabilities

Level 2 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 for substantially the full term of the assets or liabilities

Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities

Following is a description of the valuation methodologies and inputs used for assets measured at fair value on a recurring basis and recognized in the accompanying condensed consolidated balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy.

Available-for-Sale Securities

Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. The Company did not own any securities classified within Level 1 of the hierarchy as of March 31, 2026 and December 31, 2025.

Level 2 securities include U.S. Government-sponsored agencies, municipal securities, mortgage and asset-backed securities and corporate securities. Matrix pricing is a mathematical technique widely used in the banking industry to value investment securities.

In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Fair values are calculated using discounted cash flows. Discounted cash flows are calculated based off of the anticipated future cash flows updated to incorporate loss severities. Rating agency and industry research reports as well as default and deferral activity are reviewed and incorporated into the calculation. The Company did not own any securities classified within Level 3 of the hierarchy as of March 31, 2026 or December 31, 2025.

Servicing Asset

Fair value is based on a loan-by-loan basis taking into consideration the origination to maturity dates of the loans, the current age of the loans and the remaining term to maturity. The valuation methodology utilized for the servicing asset begins with generating estimated future cash flows for each servicing asset based on their unique characteristics and market-based assumptions for prepayment speeds and costs to service. The present value of the future cash flows is then calculated utilizing market-based discount rate assumptions (Level 3).

Interest Rate Swap Agreements Back-to-Back

The Company offers interest rate swaps to certain loan customers to allow them to hedge the risk of rising interest rates on their variable rate loans. The Company originates a variable rate loan and enters into a variable-to-fixed interest rate contract with the customer. The Company also enters into an offsetting interest rate swap with a correspondent bank. These back-to-back swap agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a discounted cash flow approach. The fair value assets and liabilities of centrally clear interest rate swaps are net of variation margin settled-to-market (Level 2).

The following tables present the fair value measurements of assets and liabilities recognized in the accompanying condensed consolidated balance sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2026 and December 31, 2025.

The following tables reconcile the beginning and ending balances of recurring fair value measurements recognized in the accompanying condensed consolidated balance sheets using significant unobservable (Level 3) inputs for the three months ended March 31, 2026 and 2025.

The following describes the valuation methodologies and inputs used for assets measured at fair value on a nonrecurring basis, as well as the general classification of such assets pursuant to the valuation hierarchy.

Individually Analyzed Collateral Dependent Loans

Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. The amount of impairment may be determined based on the fair value of the underlying collateral, less costs to sell, the estimated present value of future cash flows, or the loan’s observable market price.

If the individually evaluated loan is identified as collateral dependent, the fair value of the underlying collateral, less costs to sell, is used to measure impairment. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. If the individually evaluated loan is not collateral dependent, the Company utilizes a discounted cash flow analysis to measure impairment.

Individually evaluated loans with a specific valuation allowance based on the value of the underlying collateral or a discounted cash flow analysis are classified as Level 3 assets.

The following table presents the fair value measurements of assets and liabilities recognized in the accompanying condensed consolidated balance sheets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurement falls at March 31, 2026 and December 31, 2025.

Significant Unobservable (Level 3) Inputs

The following tables present quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements.

The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying condensed consolidated balance sheets at amounts other than fair value.

Cash and Cash Equivalents

For these instruments, the carrying amount is a reasonable estimate of fair value.

Securities Held-to-Maturity

Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows.

Level 2 securities include agency mortgage-backed securities - residential, municipal securities and corporate securities. Matrix pricing is a mathematical technique widely used in the banking industry to value investment securities.

In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Fair values are calculated using discounted cash flows. Discounted cash flows are calculated based off of the anticipated future cash flows updated to incorporate loss severities. Rating agency and industry research reports as well as default and deferral activity are reviewed and incorporated into the calculation. The Company did not own any securities classified within Level 3 of the hierarchy as of March 31, 2026 or December 31, 2025.

Loans Held-for-Sale

For loans that are sold in an active secondary market, the fair value of these loans is estimated based on secondary market price indications for loans with similar interest rate and maturity characteristics. The fair value of other loans held-for-sale approximates carrying value.

Net Loans

The fair value of loans is estimated on an exit price basis incorporating discounts for credit, liquidity and marketability factors.

Accrued Interest Receivable

The fair value of these financial instruments approximates carrying value.

Federal Home Loan Bank of Indianapolis Stock

The fair value of this financial instrument approximates carrying value.

Deposits

The fair value of noninterest-bearing and interest-bearing demand deposits, savings and money market accounts approximates carrying value. The fair value of fixed maturity certificates of deposit and brokered deposits are estimated using rates currently offered for deposits of similar remaining maturities.

Advances from Federal Home Loan Bank

The fair value of fixed rate advances is estimated using rates currently available for advances with similar remaining maturities. The carrying value of variable rate advances approximates fair value.

Subordinated Debt

The fair value of the Company’s publicly traded subordinated debt is obtained from quoted market prices. The fair value of the Company’s remaining subordinated debt is estimated using discounted cash flow analysis, based on current borrowing rates for similar types of debt instruments.

Accrued Interest Payable

The fair value of these financial instruments approximates carrying value.

Commitments

The fair value of commitments to extend credit are based on fees currently charged to enter into similar agreements with similar maturities and interest rates. The Company determined that the fair value of commitments was zero based on the contractual value of outstanding commitments at each of March 31, 2026 and December 31, 2025.

The following tables present the carrying value and estimated fair value of all financial assets and liabilities that are not measured at fair value on a recurring basis at March 31, 2026 and December 31, 2025.

Note 12: Derivative Financial Instruments

The Company uses derivative financial instruments from time to time to help manage exposure to interest rate risk and the effects that changes in interest rates may have on net income and the fair value of assets and liabilities. The Company enters into interest rate swap agreements as part of its asset/liability management strategy to help manage its interest rate risk position.

The Company entered into offsetting interest rate swaps with a correspondent bank. These back-to-back swap agreements are intended to offset each other and allow the Company to originate a variable rate loan, while providing a contract for fixed interest payments for the customer. The net cash flow for the Company is equal to the interest income received from a variable rate loan originated with the customer. The fair value of these derivatives is based on a discounted cash flow approach. The fair value assets and liabilities of centrally cleared interest rate swaps are net of variation margin settled-to-market.

In March 2021, the Company terminated the last layer of interest rate swaps associated with available-for-sale agency mortgage-backed securities - residential, which resulted in swap termination payments to counterparties totaling $1.9 million. The corresponding fair value hedging adjustment was allocated pro-rata to the underlying hedged securities and is being amortized over the remaining lives of the designated securities. The Company had amortization expense totaling less than $0.1 million for both the three months ended March 31, 2026 and 2025, which was recognized as a reduction to interest income on securities.

In June 2020, the Company terminated all fair value hedging relationships associated with loans, which resulted in swap termination payments to counterparties totaling $46.1 million. The corresponding loan fair value hedging adjustment as of the date of termination is being amortized over the remaining lives of the designated loans, which have a weighted average term to maturity of 8.6 years as of March 31, 2026. The Company had amortization expense totaling $1.0 million and $0.9 million for the three months ended March 31, 2026, and 2025, respectively, related to these previously terminated fair value hedges which was recognized as a reduction to interest income on loans.

The following table presents the notional amount and fair value of interest rate swaps utilized by the Company at March 31, 2026 and December 31, 2025.

The fair value of interest rate swaps was estimated using a discounted cash flow method that incorporates current market interest rates as of the balance sheet date.

Back-to-back swaps consist oftwo interest-rate swaps (a customer swap and an offsetting counterparty swap). As a result of this offsetting relationship, no net gains or losses are recognized in income. The Company received no cash collateral from counterparties as security for their obligations related to these swap transactions at both March 31, 2026 and December 31, 2025. The Company pledged cash collateral of $0.3 million to counterparties as security for its obligations related to these agreements at both March 31, 2026 and December 31, 2025.

Note 13: Accumulated Other Comprehensive Loss

The components of accumulated other comprehensive loss, included in stockholders' equity, for the three months ended March 31, 2026 and 2025, respectively, are presented in the table below.

Note 14: Segment Information

The Company operates as a single reportable segment, managing the business and assessing financial performance on a consolidated basis. While there are several lines of business within the operating segment, they are closely interrelated and cannot operate independently. Accordingly, the Chief Operating Decision Maker (“CODM”) evaluates operations and financial performance on a Company-wide basis and all of the Company’s operations are aggregated intoone reportable operating segment.

The CODM regularly receives and reviews the Company’s net income on a consolidated basis and uses key metrics to evaluate the overall performance of the Company and make decisions regarding the allocation of resources. Additionally, the CODM reviews budget-to-actual variances to analyze these profit measures as a single operating segment.

The function of the CODM is performed by the Finance Committee. This Committee consists of the highest level of management that is responsible for the Company’s overall resource allocation and performance. The Finance Committee includes the Chairman and Chief Executive Officer, President and Chief Operating Officer and Executive Vice President and Chief Financial Officer.
