1ST SOURCE CORPORATION

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 — Accounting Policies

1st Source Corporation is a bank holding company headquartered in South Bend, Indiana that provides, through its subsidiaries (collectively referred to as “1st Source” or “the Company”), a broad array of financial products and services.

Basis of Presentation – The accompanying unaudited consolidated financial statements reflect all adjustments (all of which are normal and recurring in nature) which are, in the opinion of management, necessary for a fair presentation of the consolidated financial position, the results of operations, changes in comprehensive income (loss), changes in shareholders’ equity, and cash flows for the periods presented. These unaudited consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission (SEC) and, therefore, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP) have been omitted.

The Notes to the Consolidated Financial Statements appearing in 1st Source Corporation’s Annual Report on Form 10-K ~~(2022~~(2023 Annual Report), which include descriptions of significant accounting policies, should be read in conjunction with these interim financial statements. The Consolidated Statement of Financial Condition at December 31, ~~2022~~2023 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by GAAP for complete financial statements. Certain amounts in the prior period consolidated financial statements have been reclassified to conform to the current period presentation.

Use of Estimates in the Preparation of Financial Statements – Financial statements prepared in accordance with GAAP require the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expense during the reporting period. Actual results could differ from those estimates.

Loans and Leases – Loans are stated at the principal amount outstanding, net of unamortized deferred loan origination fees and costs and net of unearned income. Interest income is accrued as earned based on unpaid principal balances. Origination fees and direct loan and lease origination costs are deferred, and the net amount amortized to interest income over the estimated life of the related loan or lease. Loan commitment fees are deferred and amortized into other income over the commitment period.

Direct financing leases are carried at the aggregate of lease payments plus estimated residual value of the leased property, net of unamortized deferred lease origination fees and costs and unearned income. Only those costs incurred as a direct result of closing a lease transaction are capitalized and all other initial direct costs are expensed immediately. Interest income on direct financing leases is recognized over the term of the lease to achieve a constant periodic rate of return on the outstanding investment.

Accrued interest is included in Accrued Income and Other Assets on the Consolidated Statements of Financial Condition and is excluded from the calculation of the allowance for credit losses. The accrual of interest on loans and leases is discontinued when a loan or lease becomes contractually delinquent for 90 days, or when an individual analysis of a borrower’s credit worthiness indicates a credit should be placed on nonperforming status, except for residential mortgage loans and consumer loans that are well secured and in the process of collection. Residential mortgage loans are placed on nonaccrual at the time the loan is placed in foreclosure. When interest accruals are discontinued, interest credited to income in the current year is reversed and interest accrued in the prior year is charged to the allowance for loan and lease losses. However, in some cases, the Company may elect to continue the accrual of interest when the net realizable value of collateral is sufficient to cover the principal and accrued interest. When a loan or lease is classified as nonaccrual and the future collectability of the recorded loan or lease balance is doubtful, collections on interest and principal are applied as a reduction to principal outstanding. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured, which is typically evidenced by a sustained repayment performance of at least six months.

Occasionally, the Company modifies loans and leases to borrowers in financial distress (typically denoted by internal credit quality graded “substandard” or worse) by providing term extensions, other-than-insignificant payment delays, or interest rate reductions. In some cases, a combination of modifications are made to the same loan or lease. These modifications typically result from the Company’s loss mitigation activities. If the Company determines that the value of the modified loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance for loan and lease losses estimate or a charge-off to the allowance for loan and lease losses.

Note 2 — Recent Accounting Pronouncements

Investments-Equity Method and Joint Ventures: In March 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards (ASU) No. 2023-02 “Investments Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method.” These amendments allow reporting entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. This guidance is effective for public business entities for fiscal years including interim periods within those fiscal years, beginning after December 15, 2023. Early adoption is permitted in any interim period. The Company ~~is assessing~~adopted ASU 2023-02 on January 1, 2024, and ~~its~~it had no impact on its accounting and disclosures.

Fair Value Measurements: In June 2022, the FASB issued ASU No. 2022-03 “Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions.” These amendments clarify that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. This guidance is effective for public business entities for fiscal years, including interim periods within those fiscal years, beginning after December 15, 2023. ~~Early adoption is permitted.~~ The Company ~~has assessed~~adopted ASU 2022-03 on January 1, 2024, and ~~does not expect~~ it ~~to have a material~~had no impact on its accounting and disclosures.

~~Reference Rate Reform:~~Income Taxes: In ~~March 2020,~~December 2023, the FASB issued ASU No. ~~2020-04~~ ~~“Reference Rate Reform~~2023-09 “Income Taxes (Topic ~~848)~~740): ~~Facilitation~~Improvements to Income Tax Disclosures.” Among other things, these amendments require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than five percent of the ~~Effects of Reference Rate Reform on Financial Reporting.”~~ These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. In January 2021, the FASB issued ASU 2021-01 which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affectedamount computed by multiplying pretax income (loss) by the ~~discounting transition. In~~applicable statutory income tax rate.) The amendments also require that all entities disclose on an annual basis the following information about income taxes paid: (1) the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and (2) the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received.) This guidance is effective for public business entities for annual periods beginning after December ~~of 2022, the FASB~~15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued ~~ASU No. 2022-06 which extended the period of time preparers can utilize the reference rate reform relief guidance in Topic 848.~~or made available for issuance. The ~~guidance ensures the relief in Topic 848 covers the period of time during which~~amendments should be applied on a ~~significant number of modifications may take place and the ASU defers the sunset date of Topic 848 from December 31, 2022 to December 31, 2024.~~prospective basis although retrospective application is permitted. The Company ~~implemented~~is continuing to assess ASU 2023-09 and its ~~transition plan away from LIBOR as of June 30, 2023. The adoption of these ASUs did not have a material~~ impact on its accounting and disclosures.

Segment Reporting: In November 2023, the FASB issued ASU 2023-07 “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” These amendments require, among other things, that a public entity that has a single reportable segment provide all the disclosures required by the amendments in this ASU and all existing segment disclosures in Topic 208. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply the amendments retrospectively to all periods presented in the financial statements. The Company is continuing to assess ASU 2023-07 and its impact on its accounting and disclosures.

The Company does not consider available-for-sale securities with unrealized losses at ~~September 30, 2023~~March 31, 2024 to be experiencing credit losses and recognized no resulting allowance for credit losses. The Company does not intend to sell these investments and it is more likely than not that the Company will not be required to sell these investments before recovery of the amortized cost basis, which may be the maturity dates of the securities. The unrealized losses occurred as a result of changes in interest rates, market spreads and market conditions subsequent to purchase.

Note 4 — Loan and Lease Financings

The Company evaluates loans and leases for credit quality at least annually but more frequently if certain circumstances occur (such as material new information which becomes available and indicates a potential change in credit risk). The Company uses two methods to assess credit risk: loan or lease credit quality grades and credit risk classifications. The purpose of the loan or lease credit quality grade is to document the degree of risk associated with individual credits as well as inform management of the degree of risk in the portfolio taken as a whole. Credit risk classifications are used to categorize loans by degree of risk and to designate individual or committee approval authorities for higher risk credits at the time of origination. Credit risk classifications include categories for: Acceptable, Marginal, Special Attention, Special Risk, Restricted by Policy, Regulated and Prohibited by Law.

Table of Contents

All loans and leases, except residential real estate ~~and~~loans‚ home equity loans, and consumer loans, are assigned credit quality grades on a scale from 1 to 12, with grade 1 representing superior credit quality. The criteria used to assign grades to extensions of credit that exhibit potential problems or well-defined weaknesses are primarily based upon the degree of risk and the likelihood of orderly repayment, and their effect on the Company’s safety and soundness. Loans or leases graded 7 or weaker are considered “special attention” credits and, as such, relationships in excess of $250,000 are reviewed quarterly as part of management’s evaluation of the appropriateness of the allowance for loan and lease losses. Grade 7 credits are defined as “watch” and contain greater than average credit risk and are monitored to limit the exposure to increased risk; grade 8 credits are “special mention” and, following regulatory guidelines, are defined as having potential weaknesses that deserve management’s close attention. Credits that exhibit well-defined weaknesses and a distinct possibility of loss are considered “classified” and are graded 9 through 12 corresponding to the regulatory definitions of “substandard” (grades 9 and 10) and the more severe “doubtful” (grade 11) and “loss” (grade 12). For residential real estate and home equity and consumer loans, credit quality is based on the aging status of the loan and by payment activity. Nonperforming loans are those loans which are on nonaccrual status or are 90 days or more past due.

Below is a summary of the Company’s loan and lease portfolio segments and a discussion of the risk characteristics relevant to each portfolio segment.

Commercial and agricultural – loans are to entities within the Company’s local market communities. Loans are for business or agri-business purposes and include working capital lines of credit secured by accounts receivable and inventory that are generally renewable annually and term loans secured by equipment with amortizations based on the expected life of the underlying collateral, generally three to seven years. These loans are typically further supported by personal guarantees. Commercial exposure is to a wide range of industries and services. Risks in this sector are also varied and are most impacted by general economic conditions. Risk mitigants include appropriate underwriting and monitoring and, when appropriate, government guarantees, including SBA and FSA.

~~Solar~~Renewable energy – loans are for the purpose of financing solar related projects and may include construction draw notes, operating loans, letters of credit and may entail a tax equity structure. Collateral in a multi-state area includes tangible assets of the borrower, assignment of intangible assets including power purchase agreements, and pledges of permits and licenses. Financing is provided to qualified borrowers throughout the continental United States with an emphasis on the region east of the Rocky Mountains.

Auto and light truck – loans are secured by vehicles and borrowers are nationwide. The portfolio predominantly consists of loans to borrowers in the auto rental and commercial auto leasing industries. Borrowers in the auto rental segment are primarily independent auto rental entities with on-airport and off-airport locations, and some insurance replacement business. Loan amortizations are relatively short, generally eighteen months, but up to four years. Auto leasing customers lease to businesses and the Company takes assignment of the lease stream and places its lien on the vehicles. Terms are generally longer than the auto rental sector, three to seven years and match the underlying leases. Risks in both these segments include economic risks and collateral risks, principally used vehicle values.

Medium and heavy duty truck – loans and full-service truck leases are secured by heavy-duty trucks, commonly Class 8 trucks, and are generally personally guaranteed. In addition to economic risks, collateral risk is significant. Financing is generally at full cost, plus additional expenditures to get the vehicle operational, such as taxes, insurance and fees. It takes three to four years of debt amortization to reach an equity position in the collateral.

Aircraft – loans are to domestic and foreign borrowers with the domestic segment further divided into two pools: 1) personal and business use, and 2) dealers and operators. The Company’s focus for the foreign sector is Latin America, principally Mexico and Brazil. Loans are primarily secured by new and used business jets and helicopters, with appropriate advances, amortizations of ten to fifteen years, and are generally guaranteed by individuals. The most significant risk in the Aircraft portfolio is collateral risk - volatility in underlying values and maintenance concerns. The portfolio is subject to national and global economic risks.

Construction equipment – loans are to borrowers throughout the country secured by specific equipment. The borrowers include highway and road builders, asphalt producers and pavers, suppliers of aggregate products, site developers, frac sand operations, general construction equipment dealers and operators, and crane rental entities. Generally, loans include personal guarantees. The construction equipment industry is heavily dependent on both the U.S. and global economy. Market growth is reliant on investments from public and private sectors into urbanization and infrastructure projects.

Commercial real estate – loans are generally to entities within the local market communities served by the Company with advances generally within regulatory guidelines. Historically, the Company’s exposure to commercial real estate has been primarily to the less risky owner-occupied segment. The non-owner-occupied segment accounts for less than half of the commercial real estate portfolio and includes hotels, apartment complexes and warehousing facilities. There is limited exposure to construction loans. Many commercial real estate loans carry personal guarantees. Additional risks in the commercial real estate portfolio stem from geographical concentration in northern Indiana and southwest Michigan and general economic conditions.

Table of Contents

Residential real estate and home equity – loans predominantly include one-to-four family mortgages to borrowers in the Company’s local market communities and are appropriately underwritten and secured by residential real estate.

Consumer – loans are to individuals in the Company’s local markets and auto loans are generally secured by personal vehicles and appropriately underwritten.

Upon the Company’s determination that a modified loan or lease has subsequently been deemed uncollectible, the loan or lease is written off. Therefore, the amortized cost of the loan is reduced by the uncollectible amount and the allowance for loan and lease losses is adjusted by the same amount.

~~Troubled Debt Restructuring (TDR) Disclosures Prior to the Adoption of ASU 2022-02~~

There were no loan and lease modifications classified as a TDR during the three and nine months ended September 30, 2022. The classification between nonperforming and performing is determined at the time of modification. Modification programs focus on extending maturity dates or modifying payment patterns with most TDRs experiencing a combination of concessions. Modifications do not result in the contractual forgiveness of principal or interest. There were no modifications during the three and nine months ended September 30, 2022 that resulted in an interest rate below market rate.

Table of Contents

There were no TDR which had a payment default within the twelve months following modification during the three months ended September 30, 2022 and one TDR which had a payment default within the twelve months following modification during the nine months ended September 30, 2022. Default occurs when a loan or lease is 90 days or more past due under the modified terms or transferred to nonaccrual.

Note 5 — Allowance for Credit Losses

Allowance for Loan and Lease Losses

The allowance for credit losses is established for current expected credit losses on the Company’s loan and lease portfolios utilizing guidance in Accounting Standards Codification (ASC) Topic 326. The determination of the allowance requires significant judgment to estimate credit losses measured on a collective pool basis when similar risk characteristics exist, and for loans evaluated individually. In determining the allowance, the Company estimates expected future losses for the loan’s entire contractual term adjusted for expected payments when appropriate. The allowance estimate considers relevant available information, from internal and external sources relating to the historical loss experience, current conditions, and reasonable and supportable forecasts for the Company’s outstanding loan and lease balances. The allowance is an estimation that reflects management’s evaluation of expected losses related to the Company’s financial assets measured at amortized cost. To ensure ~~that~~ the allowance is maintained at an adequate level, a detailed analysis is performed on a quarterly basis and an appropriate provision is made to adjust the allowance.

The Company categorizes its loan portfolios into nine segments based on similar risk characteristics. Loans within each segment are collectively evaluated using either: 1) a cohort cumulative loss rate methodology (“cohort”) or, 2) the probability of default (“PD”)/loss given default (“LGD”) methodology (PD/LGD).

The following table shows the changes in the allowance for loan and lease losses, segregated by portfolio segment, for the three months ended ~~September 30, 2023~~March 31, 2024 and ~~2022.~~2023.

Economic Outlook

As of ~~September 30, 2023,~~March 31, 2024, the most significant economic factors impacting the Company’s loan portfolios are a ~~sluggish~~fragile domestic growth outlook, ~~exacerbated~~impacted by ~~persistent~~elevated inflation, ~~higher~~and high interest rates, ~~and global~~along with ongoing foreign conflicts and ~~resultant~~ elevated geopolitical uncertainty. Questions surrounding the timing and velocity of future interest rate cuts persist. The Company remains concerned about the impact of tighter credit conditions on the economy and the effect that may have on future economic growth. Consumer stressors are building, and the Company remains concerned about small businesses and their ability to control expenses and compete for labor while absorbing the impact of higher interest rates and higher cost of capital. Tightened lending conditions and the current high-rate environment are impacting commercial real estate activity. The forecast considers global and domestic economic impacts from these factors as well as other key economic factors such as change in gross domestic product and unemployment which may impact the Company’s clients. The Company’s assumption ~~was~~is that economic growth will ~~slow~~be below trend during the forecast period ~~and~~with inflation ~~will remain above~~slowly moving back towards the 2% Federal Reserve target rate resulting in an adverse impact on the loan and lease portfolio over the next two years.

As a result of geopolitical risks and economic uncertainty, the Company’s future loss estimates may vary considerably from the ~~September 30, 2023~~March 31, 2024 assumptions.

Note 7 — Mortgage Servicing Rights

The Company recognizes the rights to service residential mortgage loans for others as separate assets, whether the servicing rights are acquired through a separate purchase or through the sale of originated loans with servicing rights retained. The Company allocates a portion of the total proceeds of a mortgage loan to servicing rights based on the relative fair value. The unpaid principal balance of residential mortgage loans serviced for third parties was ~~$815.27~~$795.99 million and ~~$848.96~~$806.05 million at ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022,~~2023, respectively.

Mortgage servicing rights (MSRs) are evaluated for impairment at each reporting date. For purposes of impairment measurement, MSRs are stratified based on the predominant risk characteristics of the underlying servicing, principally by loan type. If temporary impairment exists within a tranche, a valuation allowance is established through a charge to income equal to the amount by which the carrying value exceeds the fair value. If it is later determined all or a portion of the temporary impairment no longer exists for a particular tranche, the valuation allowance is reduced through a recovery of income.

The following table shows changes in the carrying value of MSRs and the associated valuation allowance.

This difference represents increases in the fair value of certain MSRs that could not be recorded above cost basis.

Mortgage loan contractual servicing fees, including late fees and ancillary income, were ~~$0.63~~$0.61 million and ~~$0.69~~$0.66 million for the three months ended ~~September 30,~~March 31, 2024 and 2023, ~~and 2022, respectively.

Mortgage loan contractual servicing fees are included in Mortgage Banking on the Consolidated Statements of Income.

Note 8 — Commitments and Financial Instruments with Off-Balance-Sheet Risk

Financial Instruments with Off-Balance-Sheet Risk — 1st Source and its subsidiaries are parties to financial instruments with off-balance-sheet risk in the normal course of business. These off-balance-sheet financial instruments include commitments to originate and sell loans and standby letters of credit. The instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition.

The following table shows financial instruments whose contract amounts represent credit risk.


(Dollars in thousands)	(Dollars in thousands)	September 30, 2023		December 31, 2022		(Dollars in thousands)	March 31, 2024	December 31, 2023

Commercial and similar letters of credit	Commercial and similar letters of credit	$	2,724	$	2,368

The exposure to credit loss in the event of nonperformance by the other party to the financial instruments for loan commitments and standby letters of credit is represented by the dollar amount of those instruments. The Company uses the same credit policies and collateral requirements in making commitments and conditional obligations as it does for on-balance-sheet instruments.

2019

Table of Contents

The Company grants mortgage loan commitments to borrowers, subject to normal loan underwriting standards. The interest rate risk associated with these loan commitments is managed by entering into contracts for future deliveries of loans. Loan 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.

Standby letters of credit are conditional commitments that guarantee the performance of a client to a third party. The credit risk involved in and collateral obtained when issuing standby letters of credit is essentially the same as that involved in extending loan commitments to clients. Standby letters of credit generally have terms ranging from two months to one year.

Commercial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party. Commercial letters of credit generally have terms ranging from two months to six months.

Note 9 — Derivative Financial Instruments

Commitments to originate residential mortgage loans held for sale and forward commitments to sell residential mortgage loans are considered derivative instruments. See Note 8 for further information.

The Company has certain interest rate derivative positions that are not designated as hedging instruments. Derivative assets and liabilities are recorded at fair value on the Consolidated Statements of Financial Condition and do not take into account the effects of master netting agreements. Master netting agreements allow the Company to settle all derivative contracts held with a single counterparty on a net basis, and to offset net derivative positions with related collateral, where applicable. These derivative positions relate to transactions in which the Company enters into an interest rate swap with a client while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each transaction, the Company agrees to pay interest to the client on a notional amount at a variable interest rate and receive interest from the client on the same notional amount at a fixed interest rate. At the same time, the Company agrees to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows the client to effectively convert a variable rate loan to a fixed rate. Because the terms of the swaps with the customers and the other financial institutions offset each other, with the only difference being counterparty credit risk, changes in the fair value of the underlying derivative contracts are not materially different and do not significantly impact the Company’s results of operations.

The following table shows the amounts of non-hedging derivative financial instruments.

Note 10 — Variable Interest Entities

A variable interest entity (VIE) is a partnership, limited liability company, trust or other legal entity that meets any one of the following criteria:

•The entity does not have sufficient equity to conduct its activities without additional subordinated financial support from another party.

•The entity’s investors lack the power to direct the activities that most significantly affect the entity’s economic performance.

•The entity’s at-risk holders do not have the obligation to absorb the losses or the right to receive residual returns.

2221

Table of Contents

•The voting rights of some investors are not proportional to their economic interests in the entity, and substantially all of the entity’s activities involve, or are conducted on behalf of, investors with disproportionately few voting rights.

The Company is involved in various entities that are considered to be VIEs. The Company’s investments in VIEs are primarily related to investments promoting affordable housing, community development and renewable energy sources. Some of these tax-advantaged investments support the Company’s regulatory compliance with the Community Reinvestment Act. The Company’s investments in these entities generate a return primarily through the realization of federal and state income tax credits and other tax benefits, such as tax deductions from operating losses of the investments, over specified time periods. ~~Tax~~These tax credits ~~from affordable housing investments and community development investments~~ are recognized as a reduction of tax ~~expense. Investments in renewable energy sources qualify~~expense or, for investments qualifying as investment tax credits, ~~which are recognized~~ as a reduction to the related investment asset. The Company recognized federal and state income tax credits related to its affordable housing and community development tax-advantaged investments in tax expense of ~~$0.66~~$0.80 million and ~~$0.52~~$0.66 million for the three months ended ~~September 30,~~March 31, 2024 and 2023, ~~and 2022, respectively, and $1.99 million and $1.55 million for the nine months ended September 30, 2023 and 2022,~~ respectively. The Company also recognized ~~$0.57~~$5.07 million and ~~$0.00~~$17.49 million of investment tax credits for the three months ended ~~September 30,~~March 31, 2024 and 2023, ~~and 2022, respectively, and $25.02 million and $9.48 million for the nine months ended September 30, 2023 and 2022,~~ respectively.

The Company is not required to consolidate VIEs in which it has concluded it does not have a controlling financial interest, and thus is not the primary beneficiary. In such cases, the Company does not have both the power to direct the entities’ most significant activities and the obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIEs. As a limited partner in these operating partnerships, the Company is allocated credits and deductions associated with the underlying properties. The Company has determined that it is not the primary beneficiary of these investments because the general partners have the power to direct activities that most significantly influence the economic performance of their respective partnerships.

The Company’s investments in these unconsolidated VIEs are carried in Other Assets on the Consolidated Statements of Financial Condition. The Company’s unfunded capital and other commitments related to these unconsolidated VIEs are generally carried in Other Liabilities on the Consolidated Statements of Financial Condition. The Company’s maximum exposure to loss from these unconsolidated VIEs includes the investment recorded on the ~~Company’s~~ Consolidated Statements of Financial Condition, net of unfunded capital commitments, and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. While the Company believes potential losses from these investments are remote, the maximum exposure was determined by assuming a scenario where the community-based business projects, housing projects, and renewable energy projects completely fail and do not meet certain taxing authority compliance requirements, resulting in recapture of the related tax credits.

The following table provides a summary of investments in affordable housing, community development, and renewable energy VIEs that the Company has not consolidated.

The assets of the consolidated VIEs are reported in Other Assets, the liabilities are reported in Other Liabilities, and the non-controlling interest is reported in Equity on the Consolidated Statements of Financial Condition. The assets of a particular VIE are the primary source of funds to settle its obligations. The creditors of the VIE do not have recourse to the general credit of the Company. The Company’s exposure to the consolidated VIE is generally limited to the carrying value of its variable interest plus any related tax credits previously recognized.

~~Table of Contents~~

Additionally, the Company sponsors one trust, 1st Source Master Trust (Capital Trust), of which 100% of the common equity is owned by the Company. The Capital Trust was formed in 2007 for the purpose of issuing corporation-obligated mandatorily redeemable capital securities (the capital securities) to third-party investors and investing the proceeds from the sale of the capital securities solely in junior subordinated debenture securities of the Company (the subordinated notes). The subordinated notes held by the Capital Trust are the sole assets of the Capital Trust. The Capital Trust qualifies as a variable interest entity for which the Company is not the primary beneficiary and is therefore reported in the financial statements as an unconsolidated subsidiary. The junior subordinated debentures are reflected as subordinated notes on the Consolidated Statements of Financial Condition with the corresponding interest distributions reflected as Interest Expense on the Consolidated Statements of Income. The common shares issued by the Capital Trust are included in Other Assets on the Consolidated Statements of Financial Condition.

Table of Contents

Distributions on the capital securities issued by the Capital Trust are payable quarterly at a rate per annum equal to the interest rate being earned by the Capital Trust on the subordinated notes held by the Capital Trust. The capital securities are subject to mandatory redemption, in whole or in part, upon repayment of the subordinated notes. The Company has entered into agreements which, taken collectively, fully and unconditionally guarantee the capital securities subject to the terms of each of the guarantees. The capital securities held by the Capital Trust qualify as Tier 1 capital under Federal Reserve Board guidelines.

Note 11 — Earnings Per Share

Earnings per common share is computed using the two-class method. Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the applicable period, excluding outstanding participating securities. Participating securities include non-vested restricted stock awards. Non-vested restricted stock awards are considered participating securities to the extent the holders of these securities receive non-forfeitable dividends at the same rate as holders of common stock. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation using the treasury stock method.

Stock options, where the exercise price was greater than the average market price of the common shares, were excluded from the computation of diluted earnings per common share because the result would have been antidilutive. There were no stock options outstanding as of ~~September 30, 2023~~March 31, 2024 and ~~2022.~~2023. The following table presents a reconciliation of the number of shares used in the calculation of basic and diluted earnings per common share.

Note 12 — Stock Based Compensation

As of ~~September 30, 2023,~~March 31, 2024, the Company had four active stock-based employee compensation plans, which are more fully described in Note 16 of the Consolidated Financial Statements in 1st Source’s Annual Report on Form 10-K for the year ended December 31, ~~2022.~~2023. These plans include three executive stock award plans, the Executive Incentive Plan (EIP), the Restricted Stock Award Plan (RSAP), the Strategic Deployment Incentive Plan (SDP); and the Employee Stock Purchase Plan (ESPP). The 2011 Stock Option Plan was approved by the shareholders on April 21, 2011 but the Company had not made any grants through ~~September 30, 2023.~~March 31, 2024.

Table of Contents

Stock-based compensation expense for all stock-based compensation awards granted is based on the grant-date fair value. For all awards except stock option awards, the grant date fair value is either the fair market value per share or book value per share (corresponding to the type of stock awarded) as of the grant date. For stock option awards, the grant date fair value is estimated using the Black-Scholes option pricing model. For all awards, the Company recognizes these compensation costs on a straight-line basis over the requisite service period of the award, for which the Company uses the related vesting term.

Total fair value of options vested and expensed was zero for the ~~nine~~three months ended ~~September 30, 2023~~March 31, 2024 and ~~2022.~~2023. As of ~~September 30,~~March 31, 2024 and 2023 ~~and 2022~~ there were no outstanding stock options. There were no stock options exercised during the ~~nine~~three months ended ~~September 30, 2023~~March 31, 2024 and ~~2022.~~2023. All shares issued in connection with stock option exercises are issued from available treasury stock.

As of ~~September 30, 2023,~~March 31, 2024, there was ~~$11.02~~$13.66 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements. That cost is expected to be recognized over a weighted-average period of ~~3.45~~3.61 years.

The total amount of unrecognized tax benefits that would affect the effective tax rate if recognized was zero at ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022.~~2023. Interest and penalties are recognized through the income tax provision. For the three ~~and nine~~ months ended ~~September 30,~~March 31, 2024 and 2023, ~~and 2022,~~ the Company recognized no interest or penalties. There were no accrued interest and penalties at ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022.~~2023.

Tax years that remain open and subject to audit include the federal ~~2019-2022~~2020-2023 years and the Indiana ~~2019-2022~~2020-2023 years. The Company does not anticipate a significant change in the amount of uncertain tax positions within the next 12 months.

Note 15 — Fair Value Measurements

The Company records certain assets and liabilities at fair value. 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 at the measurement date. Fair value measurements are also utilized to determine the initial value of certain assets and liabilities, to perform impairment assessments, and for disclosure purposes. The Company uses quoted market prices and observable inputs to the maximum extent possible when measuring fair value. In the absence of quoted market prices, various valuation techniques are utilized to measure fair value. When possible, observable market data for identical or similar financial instruments is used in the valuation. When market data is not available, fair value is determined using valuation models that incorporate management’s estimates of the assumptions a market participant would use in pricing the asset or liability.

Fair value measurements are classified within one of three levels based on the observability of the inputs used to determine fair value, as follows:

•Level 1 — The valuation is based on quoted prices in active markets for identical instruments.

~~Table of Contents~~

•Level 2 — The valuation is based on observable inputs such as quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market.

•Level 3 — The valuation is based on unobservable inputs that are supported by minimal or no market activity and that are significant to the fair value of the instrument. Level 3 valuations are typically performed using pricing models, discounted cash flow methodologies, or similar techniques that incorporate management’s own estimates of assumptions that market participants would use in pricing the instrument, or valuations that require significant management judgment or estimation.

Table of Contents

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

The Company elected fair value accounting for mortgages held for sale and for its best-efforts forward sales commitments. The Company economically hedges its mortgages held for sale at the time the interest rate locks are issued to the customers. The Company believes the election for mortgages held for sale will reduce certain timing differences and better match changes in the value of these assets with changes in the value of derivatives or best-best efforts forward sales commitments. At ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022,~~2023, all mortgages held for sale were carried at fair value.

The following table shows the differences between the fair value carrying amount of mortgages held for sale measured at fair value and the aggregate unpaid principal amount the Company is contractually entitled to receive at maturity.

Financial Instruments on Recurring Basis:

The following is a description of the valuation methodologies used for financial instruments measured at fair value on a recurring basis:

Investment securities available-for-sale are valued primarily by a third-party pricing agent. Prices supplied by the independent pricing agent, as well as their pricing methodologies and assumptions, are reviewed by the Company for reasonableness and to ensure such prices are aligned with market levels. In general, the Company’s investment securities do not possess a complex structure that could introduce greater valuation risk. The portfolio mainly consists of traditional investments including U.S. Treasury and Federal agencies securities, Federal agency mortgage pass-through securities, and general obligation and revenue municipal bonds. Pricing for such instruments is fairly generic and is easily obtained. On a quarterly basis, prices supplied by the pricing agent are validated by comparison to prices obtained from other third-party sources for a material portion of the portfolio.

The valuation policy and procedures for Level 3 fair value measurements of available-for-sale debt securities are decided through collaboration between management of the Corporate Accounting and Funds Management departments. The changes in fair value measurement for Level 3 securities are analyzed on a periodic basis under a collaborative framework with the aforementioned departments. The methodology and variables used for input are derived from the combination of observable and unobservable inputs. The unobservable inputs are determined through internal assumptions that may vary from period to period due to external factors, such as market movement and credit rating adjustments.

Both the market and income valuation approaches are implemented using the following types of inputs:

•U.S. treasuries are priced using the market approach and utilizing live data feeds from active market exchanges for identical securities.

~~Table of Contents~~

•Government-sponsored agency debt securities and corporate bonds are primarily priced using available market information through processes such as benchmark curves, market valuations of like securities, sector groupings and matrix pricing.

•Other government-sponsored agency securities, mortgage-backed securities and some of the actively traded REMICs and CMOs, are primarily priced using available market information including benchmark yields, prepayment speeds, spreads and volatility of similar securities.

Table of Contents

•State and political subdivisions are largely grouped by characteristics, i.e., geographical data and source of revenue in trade dissemination systems. Since some securities are not traded daily and due to other grouping limitations, active market quotes are often obtained using benchmarking for like securities. Local direct placement municipal securities, with very little market activity, are priced using an appropriate market yield curve, which includes a credit spread assumption.

Mortgages held for sale and the related loan commitments and forward contracts (hedges) are valued by a third-party pricing agent. Prices supplied by the independent pricing agent, as well as their pricing methodologies, are reviewed by the Company for reasonableness and to ensure such prices are aligned with market values. On a quarterly basis, prices supplied by the pricing agent are validated by comparison to the prices obtained from other third-party sources.

Interest rate swap positions, both assets and liabilities, are valued by a third-party pricing agent using an income approach and utilizing models that use as their basis readily observable market parameters. This valuation process considers various factors including interest rate yield curves, time value and volatility factors. Validation of third-party agent valuations is accomplished by comparing those values to the Company’s swap counterparty valuations. Management believes an adjustment is required to “mid-market” valuations for derivatives tied to its performing loan portfolio to recognize the imprecision and related exposure inherent in the process of estimating expected credit losses as well as velocity of deterioration evident with systemic risks embedded in these portfolios. Any change in the mid-market derivative valuation adjustment will be recognized immediately through the Consolidated Statements of Income.

Financial Instruments on Non-recurring Basis:

The Company may be required, from time to time, to measure certain other financial assets at fair value on a non-recurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower of cost or market accounting or impairment charges of individual assets.

2927

Table of Contents

The Credit Policy Committee (CPC), a management committee, is responsible for overseeing the valuation processes and procedures for Level 3 measurements of impaired loans, other real estate and repossessions. The CPC reviews these assets on a quarterly basis to determine the accuracy of the observable inputs, generally third-party appraisals, auction values, values derived from trade publications and data submitted by the borrower, and the appropriateness of the unobservable inputs, generally discounts due to current market conditions and collection issues. The CPC establishes discounts based on asset type and valuation source; deviations from the standard are documented. The discounts are reviewed periodically, annually at a minimum, to determine they remain appropriate. Consideration is given to current trends in market values for the asset categories and gains and losses on sales of similar assets. The Loan and Funds Management Committee of the Board of Directors is responsible for overseeing the CPC.

Discounts vary depending on the nature of the assets and the source of value. Aircraft are generally valued using quarterly trade publications adjusted for engine time, condition, maintenance programs, discounted by 10%. Likewise, autos are valued using current auction values, discounted by 10%; medium and heavy duty trucks are valued using trade publications and auction values, discounted by 15%. Construction equipment is generally valued using trade publications and auction values, discounted by 20%. Real estate is valued based on appraisals or evaluations, discounted by 20% with higher discounts for property in poor condition or property with characteristics which may make it more difficult to market. Commercial loans subject to borrowing base certificates are generally discounted by 20% for receivables and 40% - 75% for inventory with higher discounts when monthly borrowing base certificates are not required or received.

Collateral-dependent impaired loans and related write-downs are based on the fair value of the underlying collateral if repayment is expected solely from the collateral. Collateral values are reviewed quarterly and estimated using customized discounting criteria, appraisals and dealer and trade magazine quotes which are used in a market valuation approach. In accordance with fair value measurements, only impaired loans for which an allowance for loan loss has been established based on the fair value of collateral require classification in the fair value hierarchy. As a result, only a portion of the Company’s impaired loans are classified in the fair value hierarchy.

The Company has established MSRs valuation policies and procedures based on industry standards and to ensure valuation methodologies are consistent and verifiable. MSRs and related adjustments to fair value result from application of lower of cost or fair value accounting. For purposes of impairment, MSRs are stratified based on the predominant risk characteristics of the underlying servicing, principally by loan type. The fair value of each tranche of the servicing portfolio is estimated by calculating the present value of estimated future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, servicing costs, and other economic factors. Prepayment rates and discount rates are derived through a third-party pricing agent. Changes in the most significant inputs, including prepayment rates and discount rates, are compared to the changes in the fair value measurements and appropriate resolution is made. A fair value analysis is also obtained from an independent third-party agent and compared to the internal valuation for reasonableness. MSRs do not trade in an active, open market with readily observable prices and though sales of MSRs do occur, precise terms and conditions typically are not readily available, and the characteristics of the Company’s servicing portfolio may differ from those of any servicing portfolios that do trade.

Other real estate is based on the fair value of the underlying collateral less expected selling costs. Collateral values are estimated primarily using appraisals and reflect a market value approach. Fair values are reviewed quarterly, and new appraisals are obtained annually. Repossessions are similarly valued.

For assets measured at fair value on a nonrecurring basis, the following represents impairment charges (recoveries) recognized on these assets during the quarter ended ~~September 30, 2023:~~March 31, 2024: collateral-dependent impaired loans - ~~$2.25~~$6.96 million; mortgage servicing rights - $0.00 million; repossessions - $0.00 million; and other real estate - $0.00 million.

These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. These estimates are subjective in nature and require considerable judgment to interpret market data. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange, nor are they intended to represent the fair value of the Company as a whole. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. The fair value estimates presented herein are based on pertinent information available to management as of the respective balance sheet date. Although the Company is not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following management’s discussion and analysis is presented to provide information concerning 1st Source Corporation and its subsidiaries’ (collectively referred to as “the Company”, “we”, and “our”) financial condition as of ~~September 30, 2023,~~March 31, 2024, as compared to December 31, ~~2022,~~2023, and the results of operations for the three ~~and nine~~ months ended ~~September 30, 2023~~March 31, 2024 and ~~2022.~~2023. This discussion and analysis should be read in conjunction with our consolidated financial statements and the financial and statistical data appearing elsewhere in this report and our ~~2022~~2023 Annual Report.

Except for historical information contained herein, the matters discussed in this document express “forward-looking statements.” Generally, the words “believe,” “contemplate,” “seek,” “plan,” “possible,” “assume,” “hope,” “expect,” “intend,” “targeted,” “continue,” “remain,” “estimate,” “anticipate,” “project,” “will,” “should,” “indicate,” “would,” “may” and other similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. Those statements, including statements, projections, estimates or assumptions concerning future events or performance, and other statements that are other than statements of historical fact, are subject to material risks and uncertainties. We caution readers not to place undue reliance on any forward-looking statements, which speak only as of the date made. We may make other written or oral forward-looking statements from time to time. Readers are advised that various important factors could cause our actual results or circumstances for future periods to differ materially from those anticipated or projected in such forward-looking statements. Such factors include, but are not limited to, changes in law, regulations or GAAP; our competitive position within the markets we serve; increasing consolidation within the banking industry; unforeseen changes in interest rates; unforeseen changes in loan prepayment assumptions; unforeseen downturns in or major events affecting the local, regional or national economies or the industries in which we have credit concentrations; potential impacts of the COVID-19 pandemic; and other matters discussed in our filings with the SEC, including our Annual Report on Form 10-K for ~~2022,~~2023, which filings are available from the SEC. We undertake no obligation to publicly update or revise any forward-looking statements.

FINANCIAL CONDITION

Our total assets at ~~September 30, 2023~~March 31, 2024 were ~~$8.53~~$8.67 billion, ~~an increase~~a decrease of ~~$185.64~~$60.12 million or ~~2.23%~~0.69% from December 31, ~~2022.~~2023. Total investment securities available-for-sale were ~~$1.61~~$1.58 billion, a decrease of ~~$169.89~~$39.36 million or ~~9.57%~~2.43% from December 31, ~~2022.~~2023. The largest contributor to the decrease in investment securities available-for-sale was ~~securities sales and maturities~~expected redemptions which were used to ~~support liquidity and~~ fund loan ~~growth.~~growth and pay down borrowings. Federal funds sold and interest bearing deposits with other banks were ~~$35.41~~$39.38 million, a decrease of ~~$2.69~~$12.81 million or ~~7.06%~~24.55% from December 31, ~~2022.~~2023. The decrease in federal funds sold and interest bearing deposits with other banks was due to lower interest bearing deposits at other banks which were used to purchase securities, fund loan ~~growth.~~growth, and pay down borrowings.

Total loans and leases were ~~$6.35~~$6.56 billion, an increase of ~~$342.49~~$44.27 million or ~~5.70%~~0.68% from December 31, ~~2022.~~2023. The largest contributors to the increase in loans and leases was growth in the ~~construction equipment~~auto and light truck, aircraft and renewable energy portfolios, offset by a decrease in the commercial ~~real estate portfolios.~~and agricultural loan portfolio. Our foreign loan and lease balances, all denominated in U.S. dollars were $~~309.17~~291.10 million and $~~297.46~~302.41 million as of ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022,~~2023, respectively. Foreign loans and leases are in aircraft financing. Loan and lease balances to borrowers in Brazil and Mexico were $~~121.99~~118.53 million and $~~156.46~~142.10 million as of ~~September 30, 2023,~~March 31, 2024, respectively, compared to ~~$129.98~~$119.38 million and ~~$136.68~~$147.61 million as of December 31, ~~2022,~~2023, respectively. As of ~~September 30, 2023~~March 31, 2024 and December 31, ~~2022~~2023 there was not a significant concentration in any other country.

Equipment owned under operating leases was ~~$24.10~~$16.69 million, a decrease of ~~$7.60~~$3.68 million, or ~~23.99%~~18.04% compared to December 31, ~~2022.~~2023. The largest contributor to the decrease in equipment owned under operating leases was reduced leasing volume primarily due to a change in customer preferences and continued competitive pricing pressure for new business.

Total deposits were ~~$6.97~~$7.06 billion, an increase of ~~$39.23~~$16.73 million or ~~0.57%~~0.24% from the end of ~~2022.~~2023. The largest contributors to the increase in total deposits was a rise in ~~public fund deposits,~~ time deposits and ~~brokered~~savings deposits offset by a decrease in ~~noninterest-bearing~~non-maturity deposits. Rate competition for deposits persisted during the ~~third~~first quarter across our footprint from various sources, including traditional bank and credit union competitors, money market funds, bond markets, and other non-bank alternatives.

Short-term borrowings were ~~$272.09~~$249.58 million, ~~an increase~~a decrease of ~~$56.56~~$62.78 million or ~~26.24%~~20.10% from December 31, ~~2022~~2023 due primarily to ~~an increase in~~pay downs of short-term FHLB borrowings offset by ~~a decrease~~an increase in ~~repurchase agreements.~~ federal funds purchased. Long-term debt and mandatorily redeemable securities were ~~$46.53~~$39.41 million, ~~and relatively flat~~a decrease of $8.51 million from December 31, ~~2022.~~ 2023 due primarily to pay downs of long-term FHLB borrowings. Accrued expenses and other liabilities were ~~$197.18~~$183.23 million, ~~an increase~~a decrease of ~~$30.64~~$18.85 million or ~~18.40%~~9.33% from December 31, ~~2022~~2023, mainly due to annual incentive-related payments to employees and decreased unfunded partnership commitments offset by increased accrued interest ~~payable, a rise in unfunded partnership commitments,~~payables and ~~a higher liability for credit losses on unfunded loan commitments.~~accrued salaries and wages.

LIQUIDITY AND INTEREST RATE SENSITIVITY

Effective liquidity management ensures that the cash flow requirements of depositors and borrowers, as well as our operating cash needs are met. Funds are available from a number of sources, including the securities portfolio, the core deposit base, access to the national brokered certificates of deposit market, national listing service certificates of deposit, Federal Home Loan Bank (FHLB) borrowings, Federal Reserve Bank (FRB) borrowings, and the capability to package loans for sale.

We maintain prudent strategies to support a strong liquidity position. The following table represents our sources of liquidity as of ~~September 30, 2023.~~March 31, 2024.

Under Indiana law governing the collateralization of public fund deposits, the Indiana Board of Depositories determines which financial institutions are required to pledge collateral based on the strength of their financial ratings. We have been informed that no collateral is required for our public fund deposits. However, the Board of Depositories could alter this requirement in the future and adversely impact our liquidity. Our potential liquidity exposure if we must pledge collateral is approximately ~~$1.18~~$1.14 billion.

~~Nine Months Ended September 30, 2023 compared to the Nine Months Ended September 30, 2022~~

The taxable-equivalent net interest income for the nine months ended September 30, 2023 was $207.89 million, an increase of 8.04% over the same period in 2022. The net interest margin on a fully taxable-equivalent basis was 3.51% for the nine months ended September 30, 2023, compared to 3.37% for the same period in 2022.

During the nine month period ended September 30, 2023, average earning assets increased $272.30 million, up 3.56% over the comparable period in 2022. Average interest-bearing liabilities increased $496.54 million or 9.98%. The yield on average earning assets increased 149 basis points to 5.11% from 3.62% primarily due to higher rates on loans and leases, tax exempt investment securities and other investments, which include federal funds sold, time deposits with other banks, Federal Reserve Bank excess balances, Federal Reserve Bank and Federal Home Loan Bank (FHLB) stock and commercial paper. Total cost of average interest-bearing liabilities increased 193 basis points to 2.32% from 0.39% as a result of repricing of interest-bearing deposits and higher interest expense on other short-term borrowings which is predominately short-term FHLB borrowings and mandatorily redeemable securities. The result to the net interest margin, or the ratio of net interest income to average earning assets, was a net 14 basis point improvement.

The largest contributor to the improved yield on average earning assets for the nine months ended September 30, 2023, compared to the nine months ended September 30, 2022, was an increase in yields on net loans and leases of 159 basis points primarily due to market conditions as a result of Federal Reserve interest rate increases. Average loans and leases increased $667.45 million, up 12.19%. Average mortgages held for sale decreased $3.48 million or 58.29%. Average investment securities decreased $~~158.63~~ million or 8.52% which represents both the sale and maturity of securities used to support liquidity and fund loan growth. Average other investments, primarily held at the Federal Reserve Bank, decreased $233.05 million or 76.95% largely to fund loan growth.

Average interest-bearing deposits increased $485.10 million or 10.41% for the first nine months of 2023 over the same period in 2022 primarily due to the increased public fund deposits, time deposits and brokered deposit balances. The effective rate paid on average interest-bearing deposits increased 184 basis points to 2.20% from 0.36% mainly from rate competition in the market. Average noninterest-bearing deposits declined $260.91 million or 12.81% for the first nine months of 2023 over the same period in 2022 primarily due to persistent rate competition for deposits and greater utilization of excess funds by our business customers.

Average short-term borrowings increased $22.86 million or 11.49% for the first nine months of 2023 compared to the same period in 2022. Interest paid on short-term borrowings increased 282 basis points due to higher borrowing rates. Interest paid on subordinated notes increased 120 basis points due to a variable rate on one tranche. Average long-term debt and mandatorily redeemable securities balances decreased $11.42 million or 19.83%. Interest paid on long-term debt and mandatorily redeemable securities increased 863 basis points due to higher imputed interest on mandatorily redeemable securities from an increase in book value per share during 2023. Mandatorily redeemable shares are issued under the terms of one of our executive incentive compensation plans and are settled based on book value per share with changes from the previous reporting date recorded as interest expense.

Reconciliation of Non-GAAP Financial Measures

The accounting and reporting policies of 1st Source conform to generally accepted accounting principles (“GAAP”) in the United States and prevailing practices in the banking industry. However, certain non-GAAP performance measures are used by management to evaluate and measure the Company’s performance. These include taxable-equivalent net interest income (including its individual components) and net interest margin (including its individual components). Management believes that these measures provide users of the Company’s financial information a more meaningful view of the performance of the interest-earning assets and interest-bearing liabilities.

Management reviews yields on certain asset categories and the net interest margin of the Company and its banking subsidiaries on a fully taxable-equivalent (“FTE”) basis. In this non-GAAP presentation, net interest income is adjusted to reflect tax-exempt interest income on an equivalent before-tax basis. This measure ensures comparability of net interest income arising from both taxable and tax-exempt sources.

PROVISION AND ALLOWANCE FOR CREDIT LOSSES

The provision for credit losses for the three ~~and nine~~ months ended ~~September 30, 2023~~March 31, 2024, was ~~$0.86 million and $3.96~~$6.60 million compared to ~~$3.17 million and $7.90~~$3.05 million during the three ~~and nine~~ months ended ~~September 30, 2022.~~March 31, 2023. Net charge-offs of ~~$0.33~~$6.12 million or ~~0.02%~~0.38% of average loans and leases were recorded for the ~~third~~first quarter ~~2023,~~2024, compared to net ~~charge-offs~~recoveries of ~~$0.30~~$0.19 million or ~~0.02%~~0.01% of average loans and leases for the same quarter a year ago. Year-to-date net recoveries of $0.85 million or 0.02% of average loans and leases have been recorded in 2023, compared to net recoveries of $0.34 million or 0.01% of average loans and leases through September 30, 2022. Net ~~recoveries in 2023~~charge-offs recognized during the quarter were principally concentrated in the ~~auto~~commercial and ~~light truck, and aircraft portfolios.~~agricultural portfolio.

The increase of the provision for credit losses for the three months ended ~~September 30, 2023~~March 31, 2024, was ~~principally~~ driven by ~~overall~~modest loan growth during the quarter, ~~offset by a modest decline in~~higher loss rates ~~due to ongoing recoveries~~ in ~~multiple portfolios,~~our commercial and ~~a decrease~~agricultural portfolio, and overall higher special attention outstandings, most notably in ~~loan balances in a higher risk segment of~~ the auto and light truck portfolio. Risks include a ~~sluggish~~fragile domestic GDP outlook, ~~tightening~~tightened credit conditions, ~~persistent~~elevated inflation, ~~higher~~high interest rates, and geopolitical uncertainty. We remain concerned about the potential risks in our small business portfolio, as liquidity provided by government programs afforded to our lending clients ~~dissipates~~dissipates.

The possibility for economic disruption remains a concern, as geopolitical events and ~~persistently high~~elevated inflation along with ~~weak~~below-trend growth prospects raise the potential for adverse impacts in the domestic and global economies. ~~Increasing~~Higher interest rates could impact valuations of assets which collateralize our loans, and the persistently inverted yield curve may lead to tighter credit market conditions. The ~~generally weak~~ growth outlook in the U.S. and abroad ~~along with the potential for prolonged trade~~is susceptible to disruption caused by global conflicts ~~increase overall uncertainty.~~and an environment of heightened instability.

WeWe review political and economic data for these countries on a regular basis to assess the impact the environment may have on our customers. Historically, we have experienced volatile and unanticipated losses in both the foreign and domestic segments of our aircraft portfolios. Losses have been primarily attributable to unexpected declines in the value of specific aircraft collateral at a time when the borrower is experiencing financial difficulties. We review and assess aircraft values on an ongoing basis and use a tiered approach to establish advance rates and amortization schedules to limit collateral exposure.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There have been no material changes in market risks faced by 1st Source since December 31, ~~2022.~~2023. For information regarding our market risk, refer to 1st Source’s Annual Report on Form 10-K for the year ended December 31, ~~2022.~~2023.

ITEM 4.

CONTROLS AND PROCEDURES

As of the end of the period covered by this report an evaluation was carried out, under the supervision and with the participation of our management, including the Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934) pursuant to Exchange Act Rule 13a-14. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, at ~~September 30, 2023,~~March 31, 2024, our disclosure controls and procedures were effective in ensuring that information required to be disclosed by 1st Source in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and are designed to ensure that information required to be disclosed in those reports is accumulated and communicated to management as appropriate to allow timely decisions regarding required disclosure.

In addition, there were no changes in our internal control over financial reporting (as defined in Exchange Act Rule 13a-15(f)) during the ~~third~~first fiscal quarter of ~~2023~~2024 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings.

1st Source and its subsidiaries are involved in various legal proceedings that are inherent risks of, or incidental to, the conduct of our businesses. Management does not expect the outcome of any such proceedings will have a material adverse effect on our consolidated financial position or results of operations.

ITEM 1A. Risk Factors.

The Company is attentive to various risks and continuously evaluates the potential impact of such risks. Except as set forth below, where already disclosed risk factors have been updated for the current period, thereThere have been no material ~~updates or~~ changes in risks faced by 1st Source since December 31, ~~2022.~~2023. For information regarding our risk factors, refer to 1st Source’s Annual Report on Form 10-K for the year ended December 31, ~~2022.~~2023.

~~We could experience an unexpected inability to obtain needed liquiditywhich could adversely affect our business, profitability, and viability as a going concern~~— Liquidity measures the ability to meet current and future cash flow needs as they become due. The liquidity of a financial institution reflects its ability to meet loan requests, to accommodate possible outflows in deposits, and to take advantage of interest rate market opportunities and is essential to a financial institution’s business. The ability of a financial institution to meet its current financial obligations is a function of its balance sheet structure, its ability to liquidate assets, and its access to alternative sources of funds. The bank failures in 2023 exemplify the potential serious results of the unexpected inability of insured depository institutions to obtain needed liquidity to satisfy deposit withdrawal requests, including how quickly such requests can accelerate once uninsured depositors lose confidence in an institutions ability to satisfy its obligations to depositors. We seek to ensure our funding needs are met by maintaining a level of liquidity through asset and liability management. If we become unable to obtain funds when needed, it could have a material adverse effect on our business, financial condition, and results of operations. Additionally, under Indiana law governing the collateralization of public fund deposits, the Indiana Board for Depositories determines which financial institutions are required to pledge collateral based on the strength of their financial ratings. We have been informed that no collateral is required for our public fund deposits. However, the Board of Depositories could alter this requirement in the future, which could adversely affect our liquidity depending on the amount of collateral we may be required to pledge.

~~Technology security breaches~~ — Information security risks have increased due to the sophistication and activities of organized crime, hackers, terrorists and other external parties and the use of online, telephone, and mobile banking channels by clients. Any compromise of our security could impair our reputation and deter our clients from using our banking services. Information security breaches can also disrupt the operation of information systems on which we depend, adversely affecting our business operations. Such events can result in costly remediation measures and litigation or governmental investigation and responding to security breaches can place unanticipated demands on the time and attention of management. We rely on security systems to provide the protection and authentication necessary to secure transmission of data against damage by theft, fire, power loss, telecommunications failure or similar catastrophic event, as well as from security breaches, ransomware, denial of service attacks, viruses, worms, and other disruptive problems caused by hackers. Computer break-ins, phishing and other disruptions of customer or vendor systems could also jeopardize the security of information stored in and transmitted through our computer systems and network infrastructure. We maintain a cyber insurance policy that is designed to cover a majority of loss resulting from cyber security breaches, but there is no assurance such coverage or other protective measures we employ will be adequate to address all potential material adverse impacts.

We also confront the risk of being compromised by emails sent by perpetrators posing as company executives or vendors in order to dupe company personnel into sending large sums of money to accounts controlled by the perpetrators. We require all our employees to complete annual information security awareness training to increase their awareness of these risks and to engage them in our mitigation efforts. If these precautions are not sufficient to protect our systems from data breaches or compromises, our reputation and business could be adversely affected.

We depend on the services of a variety of third-party vendors to meet data processing and communication needs and we have contracted with third parties to run their proprietary software on our behalf. While we perform reviews of security controls instituted by the vendor in accordance with industry standards and institute our own internal security controls, we rely on continued maintenance of the controls by the outside party to safeguard our customer data.

Additionally, we issue debit cards which are susceptible to compromise at the point of sale via the physical terminal through which transactions are processed and by other means of hacking. The security and integrity of these transactions are dependent upon the retailers’ vigilance and willingness to invest in technology and upgrades. Issuing debit cards to our clients exposes us to potential losses which, in the event of a data breach at one or more major retailers may adversely affect our business, financial condition, and results of operations.
