OLD NATIONAL BANCORP

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

NOTE 1 – BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Old National Bancorp and its wholly-owned subsidiaries (hereinafter collectively referred to as “Old National”) and have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. Such principles require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosures of contingent assets and liabilities at the date of the financial statements and amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, the consolidated financial statements contain all the normal and recurring adjustments necessary for a fair statement of the financial position of Old National as of June 30, 2024 and December 31, 2023, and the results of its operations for the three and six months ended June 30, 2024 and 2023. Interim results do not necessarily represent annual results. Certain information and disclosures normally included in notes to consolidated annual financial statements prepared in accordance with GAAP have been condensed or omitted in this Quarterly Report on Form 10-Q pursuant to SEC rules and regulations. These financial statements should be read in conjunction with Old National’s Annual Report on Form 10-K for the year ended December 31, 2023.

All intercompany transactions and balances have been eliminated. Certain prior year amounts have been reclassified to conform to the current presentation. Such reclassifications had no effect on prior period net income or shareholders’ equity and were insignificant amounts.

NOTE 2 – RECENT ACCOUNTING PRONOUNCEMENTS

Accounting Guidance Adopted in 2024

FASB ASC 820 – In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, to 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. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The adoption of this guidance on January 1, 2024 did not have a material impact on the consolidated financial statements.

FASB ASC 323 – In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, which allows 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 ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this guidance on a modified retrospective basis on January 1, 2024 did not have a material impact on the consolidated financial statements.

FASB ASC 848 – In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from LIBOR or other interbank offered rate on financial reporting. The guidance is applicable only to contracts or hedge accounting relationships that reference LIBOR or another reference rate expected to be discontinued.

In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which defers the sunset date of relief provisions within Topic 848 from December 31, 2022 to December 31, 2024. The objective of the guidance in Topic 848 is to provide relief during the transition period.

The amendments in this ASU are effective March 12, 2020 through December 31, 2024. As of June 30, 2024, substantially all of the Company’s LIBOR exposure was addressed and remaining LIBOR-based contracts are expected to transition to alternate reference rates at their next index reset dates. Old National believes the adoption of this guidance on activities subsequent to June 30, 2024 will not have a material impact on the consolidated financial statements.

10

Accounting Guidance Pending Adoption 

FASB ASC 280 – In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments are intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. A public entity should apply the amendments retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. This 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. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

FASB ASC 740 – In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. Among other things, these amendments require that public business entities on an annual basis disclose additional information in specified categories with respect to the reconciliation of the effective tax rate to the statutory rate for federal, state, and foreign income taxes. It also requires greater detail about individual reconciling items in the rate reconciliation to the extent the impact of those items exceeds a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (loss) by the applicable statutory income tax rate). In addition, the ASU requires information pertaining to taxes paid (net of refunds received) to be disaggregated for federal, state, and foreign taxes and further disaggregated for specific jurisdictions to the extent the related amounts are equal to or greater than 5 percent of total income taxes paid (net of refunds received). The amendments in this ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

NOTE 3 – ACQUISITION AND DIVESTITURE ACTIVITY

Acquisition

CapStar Financial Holdings, Inc.

On April 1, 2024, Old National completed its acquisition of CapStar Financial Holdings, Inc. (“CapStar”) and its wholly-owned subsidiary, CapStar Bank, in an all-stock transaction. This partnership strengthens Old National’s Nashville, Tennessee presence and adds several new high-growth markets. Pursuant to the terms of the merger agreement, each outstanding share of CapStar common stock was converted into the right to receive 1.155 shares of Old National common stock plus cash in lieu of fractional shares. All system conversions related to the transaction were completed in early July of 2024.

11

The assets acquired and liabilities assumed, both intangible and tangible, were recorded at their estimated fair values as of the merger date and have been accounted for under the acquisition method of accounting. The following table presents the preliminary valuation of the assets acquired and liabilities assumed and the fair value of consideration as of the merger date:

Goodwill related to this merger will not be deductible for tax purposes.

Other intangible assets acquired included core deposit intangibles. The estimated fair value of the core deposit intangible was $46.1 million and is being amortized over an estimated useful life of 10 years.

The fair value of PCD assets was $613.5 million on the date of merger. The gross contractual amounts receivable relating to the PCD assets was $679.3 million. Old National estimates, on the date of the merger, that $23.9 million of the contractual cash flows specific to the PCD assets will not be collected.

Transaction costs primarily associated with the CapStar merger have been expensed for the three and six months ended June 30, 2024 totaling $19.4 million and $22.3 million, respectively, and additional transaction and integration costs will be expensed in future periods as incurred.

NOTE 4 – NET INCOME PER COMMON SHARE

Basic and diluted net income per common share are calculated using the two-class method. Net income applicable to common shares is divided by the weighted-average number of common shares outstanding during the period. Adjustments to the weighted-average number of common shares outstanding are made only when such adjustments will dilute net income per common share. Net income applicable to common shares is then divided by the weighted-average number of common shares and common share equivalents during the period.

The following table presents the calculation of basic and diluted net income per common share:

	Three Months Ended June 30,				Six Months Ended June 30,
(dollars and shares in thousands, except per share data)	2024		2023		2024		2023

The unrecognized losses on held-to-maturity investment securities presented in the table above do not include unrecognized losses on securities that were transferred from available-for-sale to held-to-maturity totaling $118.9 million at June 30, 2024 and $127.6 million at December 31, 2023. These unrecognized losses are included as a separate component of shareholders’ equity and are being amortized over the remaining term of the securities.

No allowance for credit losses on available-for-sale debt securities was needed at June 30, 2024 or December 31, 2023.

An allowance on held-to-maturity debt securities is maintained for certain municipal bonds to account for expected lifetime credit losses. Substantially all of the U.S. government-sponsored entities and agencies and agency mortgage-backed securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses. Therefore, for those securities, we do not record expected credit losses. The allowance for credit losses on held-to-maturity debt securities was $0.2 million at June 30, 2024 and December 31, 2023. Accrued interest receivable on the securities portfolio is excluded from the estimate of credit losses and totaled $53.0 million at June 30, 2024 and $50.3 million at December 31, 2023.

At June 30, 2024, Old National’s securities portfolio consisted of 3,039 securities, 2,792 of which were in an unrealized loss position. The unrealized losses attributable to our U.S. Treasury, U.S. government-sponsored entities and agencies, agency mortgage-backed securities, states and political subdivisions, and other securities are the result of fluctuations in interest rates and market movements. Old National’s pooled trust preferred securities are evaluated using collateral-specific assumptions to estimate the expected future interest and principal cash flows. At June 30, 2024, we had no intent to sell any securities that were in an unrealized loss position nor is it expected that we would be required to sell the securities prior to their anticipated recovery.

Old National’s pooled trust preferred securities have experienced credit defaults. However, we believe that the value of the instruments lies in the full and timely interest payments that will be received through maturity, the steady amortization that will be experienced until maturity, and the full return of principal by the final maturity of the collateralized debt obligations. Old National did not recognize any losses on these securities for the six months ended June 30, 2024 or 2023.

Equity Securities

Equity securities consist of mutual funds for Community Reinvestment Act qualified investments and diversified investment securities held in a grantor trust for participants in the Company’s nonqualified deferred compensation plan. Old National’s equity securities with readily determinable fair values totaled $85.5 million at June 30, 2024 and $80.4 million at December 31, 2023. There were losses on equity securities of $0.4 million during the three months ended June 30, 2024 and $0.1 million during the six months ended June 30, 2024, compared to gains of $0.1

16

million during the three months ended June 30, 2023 and losses of $0.7 million during the six months ended June 30, 2023.

Alternative Investments

Old National has alternative investments without readily determinable fair values that are included in other assets totaling $514.8 million at June 30, 2024, consisting of $274.9 million of illiquid investments in partnerships, limited liability companies, and other ownership interests that support affordable housing and $239.9 million of economic development and community revitalization initiatives in low-to-moderate income neighborhoods. These alternative investments totaled $449.3 million at December 31, 2023. There have been no impairments or adjustments on equity securities without readily determinable fair values, except for amortization of tax credit investments in the six months ended June 30, 2024 and 2023. See Note 9 to the consolidated financial statements for detail regarding these investments.

NOTE 6 – LOANS AND ALLOWANCE FOR CREDIT LOSSES

Loans

Old National’s loans consist primarily of loans made to consumers and commercial clients in many diverse industries, including real estate rental and leasing, manufacturing, healthcare, wholesale trade, construction, and agriculture, among others. Most of Old National’s lending activity occurs within our principal geographic markets in the Midwest and Southeast regions of the United States. Old National manages concentrations of credit exposure by industry, product, geography, client relationship, and loan size.

Old National has loan participations, which qualify as participating interests, with other financial institutions. At June 30, 2024, these loans totaled $3.5 billion, of which $1.6 billion had been sold to other financial institutions and $1.9 billion was retained by Old National. The loan participations convey proportionate ownership rights with equal priority to each participating interest holder; involve no recourse (other than ordinary representations and warranties) to, or subordination by, any participating interest holder; all cash flows are divided among the participating interest holders in proportion to each holder’s share of ownership; and no holder has the right to pledge the entire financial asset unless all participating interest holders agree.

17

The loan categories used to monitor and analyze interest income and yields are different than the portfolio segments used to determine the allowance for credit losses on loans. The allowance for credit losses was calculated by pooling loans of similar credit risk characteristics and credit monitoring procedures. The four loan portfolios used to monitor and analyze interest income and yields – commercial, commercial real estate, residential real estate, and consumer – are reclassified into seven segments of loans – commercial, commercial real estate, BBCC, residential real estate, indirect, direct, and home equity for purposes of determining the allowance for credit losses on loans. The commercial and commercial real estate loan categories shown on the balance sheet include the same pool of loans as the commercial, commercial real estate, and BBCC portfolio segments. The consumer loan category shown on the balance sheet is comprised of the same loans in the indirect, direct, and home equity portfolio segments. The portfolio segment reclassifications follow:

(2)    Includes unearned income of $199.7 million at June 30, 2024 and $93.7 million at December 31, 2023.

The risk characteristics of each loan portfolio segment are as follows:

Commercial

Commercial loans are classified primarily on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its clients.

Commercial Real Estate

Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted

18

on the property securing the loan. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. The properties securing Old National’s commercial real estate portfolio are diverse in terms of type and geographic location. Management monitors and evaluates commercial real estate loans based on collateral, geography, and risk grade criteria. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner-occupied loans.

Included with commercial real estate are construction loans, which are underwritten utilizing independent appraisal reviews, sensitivity analysis of absorption and lease rates, financial analysis of the developers and property owners, and feasibility studies, if available. Construction loans are generally based on estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders (including Old National), sales of developed property, or an interim loan commitment from Old National until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions, and the availability of long-term financing.

At 256%, Old National Bank’s applicable investor commercial real estate loans as a percentage of its Tier 1 capital plus the allowance for credit losses attributable to loans and leases remained below the regulatory guideline limit of 300% at June 30, 2024.

BBCC

BBCC loans are typically granted to small businesses with gross revenues of less than $5 million and aggregate debt of less than $1 million. Old National has established minimum debt service coverage ratios, minimum FICO scores for owners and guarantors, and the ability to show relatively stable earnings as criteria to help mitigate risk. Repayment of these loans depends on the personal income of the borrowers and the cash flows of the business. These factors can be affected by such changes as economic conditions and unemployment levels.

Residential

With respect to residential loans that are secured by 1 - 4 family residences and are generally owner occupied, Old National typically establishes a maximum loan-to-value ratio and generally requires private mortgage insurance if that ratio is exceeded. Repayment of these loans is primarily dependent on the personal income 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. Portfolio risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers.

Indirect

Indirect loans are secured by automobile collateral, generally new and used cars and trucks from auto dealers that operate within our footprint. Old National typically mitigates the risk of indirect loans by establishing minimum FICO scores, maximum loan-to-value ratios, and maximum debt-to-income ratios. Repayment of these loans depends largely on the personal income of the borrowers, which can be affected by changes in economic conditions such as unemployment levels. Portfolio risk is mitigated by the fact that the loans are of smaller amounts spread over many borrowers and ongoing reviews of dealer relationships.

Direct

Direct loans are typically secured by collateral such as auto or real estate or are unsecured. Old National has established underwriting standards such as minimum FICO scores, maximum loan-to-value ratios, and maximum debt-to-income ratios. Repayment of these loans depends largely on the personal income of the borrowers, which can be affected by changes in economic conditions such as unemployment levels. Portfolio risk is mitigated by the fact that the loans are of smaller amounts spread over many borrowers.

Home Equity

Home equity loans are generally secured by 1-4 family residences that are owner-occupied. Old National has established underwriting standards such as minimum FICO scores, maximum loan-to-value ratios, and maximum debt-to-income ratios. Repayment of these loans depends largely on the personal income of the borrowers, which can be affected by changes in economic conditions such as unemployment levels. Portfolio risk is mitigated by the

19

fact that the loans are of smaller amounts spread over many borrowers, along with monitoring of updated borrower credit scores.

Allowance for Credit Losses

Loans

Credit loss assumptions used when computing the level of expected credit losses are estimated using a model that categorizes loan pools based on loss history, delinquency status, and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. The base forecast scenario considers unemployment, gross domestic product, and the BBB ratio (BBB spread to the 10-year U.S. Treasury rate). In addition to the quantitative inputs, several qualitative factors are considered. These factors include the risk that unemployment, gross domestic product, housing product index, and the BBB ratio prove to be more severe and/or prolonged than our baseline forecast due to a variety of factors including monetary actions to control inflation, recent instability in the banking sector, global military conflicts, and global supply chain issues. Old National’s activity in the allowance for credit losses on loans by portfolio segment was as follows:

The allowance for credit losses on loans at June 30, 2024 included $23.9 million of allowance for credit losses on acquired PCD loans established through acquisition accounting adjustments on or after the CapStar acquisition date.

20

In addition, the provision for credit losses on loans in the three and six months ended June 30, 2024 included $15.3 million to establish an allowance for credit losses on non-PCD loans acquired in the CapStar transaction. Accrued interest receivable on loans is excluded from the estimate of credit losses and totaled $181.9 million at June 30, 2024, compared to $169.8 million at December 31, 2023.

Unfunded Loan Commitments

Old National maintains an allowance for credit losses on unfunded loan commitments to provide for the risk of loss inherent in these arrangements. The allowance is computed using a methodology similar to that used to determine the allowance for credit losses on loans, modified to take into account the probability of a drawdown on the commitment. The allowance for credit losses on unfunded loan commitments is classified as a liability account on the balance sheet within accrued expenses and other liabilities, while the corresponding provision for unfunded loan commitments is included in the provision for credit losses. Old National’s activity in the allowance for credit losses on unfunded loan commitments was as follows:

	Three Months Ended June 30,				Six Months Ended June 30,
(dollars in thousands)	2024		2023		2024		2023
Allowance for credit losses on unfunded loan commitments:

Balance at end of period	$	25,733	$	37,007	$	25,733	$	37,007

Credit Quality

Old National’s management monitors the credit quality of its loans on an ongoing basis with the AQR for commercial loans reviewed annually or at renewal and the performance of its residential and consumer loans based upon the accrual status refreshed at least quarterly. Internally, management assigns an AQR to each non-homogeneous commercial, commercial real estate, and BBCC loan in the portfolio. The primary determinants of the AQR are the reliability of the primary source of repayment and the past, present, and projected financial condition of the borrower. The AQR will also consider current industry conditions. Major factors used in determining the AQR can vary based on the nature of the loan, but commonly include factors such as debt service coverage, internal cash flow, liquidity, leverage, operating performance, debt burden, FICO scores, occupancy, interest rate sensitivity, and expense burden. Old National uses the following definitions for risk ratings:

Special Mention. Loans categorized as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

Classified – Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Classified – Nonaccrual. Loans classified as nonaccrual have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection in full, on the basis of currently existing facts, conditions, and values, in doubt.

Classified – Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as nonaccrual, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Pass rated loans are those loans that are other than special mention, classified – substandard, classified – nonaccrual, or classified – doubtful.

Nonaccrual and Past Due Loans

Old National does not record interest on nonaccrual loans until principal is recovered. For all loan classes, a loan is generally placed on nonaccrual status when principal or interest becomes 90 days past due unless it is well secured and in the process of collection, or earlier when concern exists as to the ultimate collectability of principal or interest. Interest accrued but not received is reversed against earnings. Cash interest received on these loans is applied to the principal balance until the principal is recovered or until the loan returns to accrual status. Loans may

24

be returned to accrual status when all the principal and interest amounts contractually due are brought current, remain current for a prescribed period, and future payments are reasonably assured.

The following table presents the aging of the amortized cost basis in past due loans by class of loans:

When management determines that foreclosure is probable, expected credit losses for collateral dependent loans are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. A loan is considered collateral dependent when the borrower is experiencing financial difficulty, and the loan is expected to be repaid substantially through the operation or sale of the collateral. The class of loan represents the primary collateral type associated with the loan. Significant quarter-over-quarter changes are reflective of changes in nonaccrual status and not necessarily associated with credit quality indicators like appraisal value. The following table presents the amortized cost basis of collateral dependent loans by class of loan:

Financial Difficulty Modifications

Occasionally, Old National modifies loans to borrowers experiencing financial difficulty in the form of principal forgiveness, term extension, an other-than-insignificant payment delay, or interest rate reduction (or a combination thereof). When principal forgiveness is provided, the amount of forgiveness is charged-off against the allowance for credit losses on loans.

During the three and six months ended June 30, 2024, there were payment defaults on $27.0 million of loans to borrowers whose loans were modified due to financial difficulties within the previous twelve months. The payment defaults did not materially impact the allowance for credit losses on loans. There were no payment defaults during the three and six months ended June 30, 2023 on loans that had been modified within the previous twelve months.

Old National had not committed to lend any material additional funds to the borrowers whose loans were modified due to financial difficulties at June 30, 2024 or December 31, 2023.

Purchased Credit Deteriorated Loans

Old National has purchased loans, for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination. The carrying amount of those loans is as follows:

(dollars in thousands)	CapStar (1)
Purchase price of loans at acquisition	$	613,494
Allowance for credit losses at acquisition	23,922
Non-credit discount/(premium) at acquisition	41,886
Par value of acquired loans at acquisition	$	679,302

(1)Old National acquired CapStar effective April 1, 2024.

NOTE 7 – LEASES

Old National has operating and finance leases for land, office space, banking centers, and equipment. These leases are generally for periods of 5 to 20 years with various renewal options. We include certain renewal options in the measurement of our right-of-use assets and lease liabilities if they are reasonably certain to be exercised. Variable lease payments that are dependent on an index or a rate are initially measured using the index or rate at the commencement date and are included in the measurement of the lease liability. Variable lease payments that are not dependent on an index or a rate are excluded from the measurement of the lease liability and are recognized in profit and loss when incurred. Variable lease payments are defined as payments made for the right to use an asset that vary because of changes in facts or circumstances occurring after the commencement date, other than the passage of time.

28

Old National has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases, non-lease components and other non-components, such as common area maintenance charges, real estate taxes, and insurance are not included in the measurement of the lease liability since they are generally able to be segregated. For certain equipment leases, Old National accounts for the lease and non-lease components as a single lease component using the practical expedient available for that class of assets. Old National does not have any material sub-lease agreements.

The components of lease expense were as follows:

Junior Subordinated Debentures

Junior subordinated debentures related to trust preferred securities are classified in “other borrowings.” Junior subordinated debentures qualify as Tier 2 capital for regulatory purposes, subject to certain limitations.

Through various mergers and acquisitions, Old National assumed junior subordinated debenture obligations related to various trusts that issued trust preferred securities. Old National guarantees the payment of distributions on the trust preferred securities issued by the trusts. Proceeds from the issuance of each of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by the trusts.

34

Old National, at any time, may redeem the junior subordinated debentures at par and, thereby cause a redemption of the trust preferred securities in whole or in part.

Net Deferred Tax Assets

Net deferred tax assets are included in other assets on the balance sheet. At June 30, 2024, net deferred tax assets totaled $456.4 million, compared to $423.3 million at December 31, 2023. No valuation allowance was required on the Company’s deferred tax assets at June 30, 2024 or December 31, 2023.

The Company’s retained earnings at June 30, 2024 included an appropriation for acquired thrifts’ tax bad debt allowances totaling $58.6 million for which no provision for federal or state income taxes has been made. If in the future, this portion of retained earnings were distributed as a result of the liquidation of the Company or its subsidiaries, federal and state income taxes would be imposed at the then applicable rates.

Old National has federal net operating loss carryforwards totaling $75.3 million at June 30, 2024 and $63.6 million at December 31, 2023. This federal net operating loss was acquired from the acquisition of Anchor BanCorp Wisconsin Inc. in 2016, First Midwest Bancorp, Inc. in 2022, and CapStar Financial Holdings, Inc. in 2024. If not used, the federal net operating loss carryforwards will begin expiring in 2032 and later. Old National has recorded state net operating loss carryforwards totaling $111.2 million at June 30, 2024 and $116.9 million at December 31, 2023. If not used, the state net operating loss carryforwards will expire from 2027 to 2036.

The federal and recorded state net operating loss carryforwards are subject to an annual limitation under Internal Revenue Code section 382. Old National believes that all of the federal and recorded state net operating loss carryforwards will be used prior to expiration.

As part of our overall interest rate risk management, Old National uses derivative instruments, including interest rate swaps, collars, caps, and floors. The notional amount does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual agreements. Derivative instruments are recognized on the balance sheet at their fair value and are not reported on a net basis.

Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. Old National’s exposure is limited to the termination value of the contracts rather than the notional, principal, or contract amounts. There are provisions in our agreements with the counterparties that allow for certain unsecured credit exposure up to an agreed threshold. Exposures in excess of the agreed thresholds are collateralized. In addition, we minimize credit risk through credit approvals, limits, and monitoring procedures.

Derivatives Designated as Hedges

Subsequent changes in fair value for a hedging instrument that has been designated and qualifies as part of a hedging relationship are accounted for in the following manner:

Cash flow hedges: changes in fair value are recognized as a component in other comprehensive income (loss).

Fair value hedges: changes in fair value are recognized concurrently in earnings.

As long as a hedging instrument is designated and the results of the effectiveness testing support that the instrument qualifies for hedge accounting treatment, 100% of the periodic changes in fair value of the hedging instrument are accounted for as outlined above. This is the case whether or not economic mismatches exist in the hedging relationship. As a result, there is no periodic measurement or recognition of ineffectiveness. Rather, the full impact of hedge gains and losses is recognized in the period in which the hedged transactions impact earnings.

The change in fair value of the hedging instrument that is included in the assessment of hedge effectiveness is presented in the same income statement line item that is used to present the earnings effect of the hedged item.

Cash Flow Hedges

Interest rate swaps of certain borrowings were designated as cash flow hedges totaling $150.0 million notional amount at both June 30, 2024 and December 31, 2023. Interest rate swaps, collars, and floors related to variable-rate commercial loan pools were designated as cash flow hedges totaling $1.8 billion notional amount at June 30, 2024 and $1.6 billion notional amount at December 31, 2023. The hedges were determined to be effective during all periods presented and we expect them to remain effective during the remaining terms.

39

Old National has designated its interest rate collars as cash flow hedges. The structure of these instruments is such that Old National pays the counterparty an incremental amount if the collar index exceeds the cap rate. Conversely, Old National receives an incremental amount if the index falls below the floor rate. No payments are required if the collar index falls between the cap and floor rates. 

Old National has designated its interest rate floor transactions as cash flow hedges. The structure of these instruments is such that Old National receives an incremental amount if the index falls below the floor strike rate. No payments are required if the index remains above the floor strike rate.

Fair Value Hedges

Interest rate swaps of certain borrowings were designated as fair value hedges totaling $1.1 billion notional amount at June 30, 2024 and $900.0 million notional amount at December 31, 2023. Interest rate swaps of certain available-for-sale investment securities were designated as fair value hedges totaling $998.1 million notional amount at both June 30, 2024 and December 31, 2023. The hedges were determined to be effective during all periods presented and we expect them to remain effective during the remaining terms.

The following table summarizes Old National’s derivatives designated as hedges:

Amounts reported in AOCI related to cash flow hedges will be reclassified to interest income or interest expense as interest payments are received or paid on Old National’s derivative instruments. During the next 12 months, we

41

estimate that $6.6 million will be reclassified to interest income and $26.5 million will be reclassified to interest expense.

Derivatives Not Designated as Hedges

Commitments to fund certain mortgage loans (interest rate lock commitments) and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. These derivative contracts do not qualify for hedge accounting. At June 30, 2024, the notional amounts of the interest rate lock commitments were $99.1 million and forward commitments were $125.4 million. At December 31, 2023, the notional amounts of the interest rate lock commitments were $25.2 million and forward commitments were $39.5 million. It is our practice to enter into forward commitments for the future delivery of residential mortgage loans to third party investors when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from our commitment to fund the loans.

Old National also enters into derivative instruments for the benefit of its clients. The notional amounts of these customer derivative instruments and the offsetting counterparty derivative instruments were $6.0 billion at both June 30, 2024 and December 31, 2023. These derivative contracts do not qualify for hedge accounting. These instruments include interest rate swaps, caps, and collars. Commonly, Old National will economically hedge significant exposures related to these derivative contracts entered into for the benefit of clients by entering into offsetting contracts with approved, reputable, independent counterparties with substantially matching terms.

Old National enters into derivative financial instruments as part of its foreign currency risk management strategies. These derivative instruments consist of foreign currency forward contracts to accommodate the business needs of its clients. Old National does not designate these foreign currency forward contracts for hedge accounting treatment.

The following table summarizes Old National’s derivatives not designated as hedges:

Fair Value of Offsetting Derivatives

Certain derivative instruments are subject to master netting agreements with counterparties that provide rights of setoff. The Company records these transactions at their gross fair values and does not offset derivative assets and liabilities in the Consolidated Balance Sheet.

NOTE 16 – COMMITMENTS, CONTINGENCIES, AND FINANCIAL GUARANTEES

Litigation

At June 30, 2024, there were certain legal proceedings pending against the Company and its subsidiaries in the ordinary course of business. While the outcome of any legal proceeding is inherently uncertain, based on information currently available, the Company’s management does not expect that any potential liabilities arising from pending litigation will have a material adverse effect on the Company’s business, financial position, or results of operations.

Credit-Related Financial Instruments

Old National holds instruments, in the normal course of business with clients, that are considered financial guarantees and are recorded at fair value. Standby letters of credit guarantees are issued in connection with agreements made by clients to counterparties. Standby letters of credit are contingent upon failure of the client to

43

perform the terms of the underlying contract. Credit risk associated with standby letters of credit is essentially the same as that associated with extending loans to clients and is subject to normal credit policies. The term of these standby letters of credit is typically one year or less. These commitments are not recorded in the consolidated financial statements.

The following table summarizes Old National Bank’s unfunded loan commitments and standby letters of credit:

(dollars in thousands)	June 30, 2024		December 31, 2023
Unfunded loan commitments	$	8,789,910	$	8,912,587
Standby letters of credit (1)	184,482		192,237

(1)Notional amount, which represents the maximum amount of future funding requirements. The carrying value was $1.5 million at June 30, 2024 and $1.3 million at December 31, 2023.

At June 30, 2024, approximately 3% of the unfunded loan commitments had fixed rates, with the remainder having floating rates ranging from 0.00% to 22.49%. The allowance for unfunded loan commitments totaled $25.7 million at June 30, 2024 and $31.2 million at December 31, 2023.

Old National is a party in risk participation transactions of interest rate swaps, which had total notional amounts of $634.9 million at June 30, 2024 and $557.8 million at December 31, 2023.

NOTE 17 – FAIR VALUE

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

•Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

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

•Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

Old National used the following methods and significant assumptions to estimate the fair value of each type of financial instrument:

Investment securities and equity securities: The fair values for investment securities and equity securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). Discounted cash flows are calculated using swap and SOFR curves plus spreads that adjust for loss severities, volatility, credit risk, and optionality. During times when trading is more liquid, broker quotes are used (if available) to validate the model. Rating agency and industry research reports as well as defaults and deferrals on individual securities are reviewed and incorporated into the calculations.

Loans held-for-sale: The fair value of loans held-for-sale is determined using quoted prices for a similar asset, adjusted for specific attributes of that loan (Level 2).

Derivative financial instruments: The fair values of derivative financial instruments are based on market quotes developed using observable inputs as of the valuation date (Level 2).

Commercial and commercial real estate loans that are deemed collateral dependent are valued using the discounted cash flows. The liquidation amounts are based on the fair value of the underlying collateral using the most recently available appraisals with certain adjustments made based on the type of property, age of appraisal, current status of the property, and other related factors to estimate the current value of the collateral. These commercial and commercial real estate loans had a principal amount of $163.2 million, with a valuation allowance of $31.4 million at June 30, 2024. Old National recorded provision expense associated with these loans totaling $7.4 million and $17.0 million for the three and six months ended June 30, 2024, respectively, compared to $7.9 million and $19.8 million for the three and six months ended June 30, 2023, respectively.

Other real estate owned and other repossessed property is measured at fair value less costs to sell on a non-recurring basis. Old National did not have any other real estate owned or other repossessed property measured at fair value on a non-recurring basis at June 30, 2024. There were $0.4 million write-downs on other real estate owned for the three and six months ended June 30, 2024, compared to $0.1 million of write-downs for the three and six months ended June 30, 2023.

Assets measured at fair value at December 31, 2023 on a non-recurring basis are summarized below:

Fair Value Option

Old National may elect to report most financial instruments and certain other items at fair value on an instrument-by-instrument basis with changes in fair value reported in net income. After the initial adoption, the election is made at the acquisition of an eligible financial asset, financial liability, or firm commitment or when certain specified reconsideration events occur. The fair value election may not be revoked once an election is made.

Loans Held-For-Sale

Old National has elected the fair value option for loans held-for-sale. For these loans, interest income is recorded in the consolidated statements of income based on the contractual amount of interest income earned on the financial assets (except any that are on nonaccrual status). None of these loans are 90 days or more past due, nor are any on nonaccrual status. Interest income for loans held-for-sale is included in the income statement totaling $0.5 million for three months ended June 30, 2024 and $0.8 million for the six months ended June 30, 2024, compared to $0.3 million and $0.5 million for the three and six months ended June 30, 2023, respectively.

Newly originated conforming fixed-rate and adjustable-rate first mortgage loans are intended for sale and are hedged with derivative instruments. Old National has elected the fair value option to mitigate accounting mismatches in cases where hedge accounting is complex and to achieve operational simplification. The fair value option was not elected for loans held for investment.

The difference between the aggregate fair value and the aggregate remaining principal balance for loans for which the fair value option has been elected was as follows: 

(dollars in thousands)	Aggregate Fair Value		Difference		Contractual Principal
June 30, 2024
Loans held-for-sale	$	66,126	$	525	$	65,601
December 31, 2023
Loans held-for-sale	$	32,006	$	621	$	31,385

Accrued interest at period end is included in the fair value of the instruments.

NON-GAAP FINANCIAL MEASURES

The Company’s accounting and reporting policies conform to GAAP and general practices within the banking industry. As a supplement to GAAP, the Company provides non-GAAP performance results, which the Company believes are useful because they assist users of the financial information in assessing the Company’s operating performance. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in the following table.

The Company presents net income per common share and net income applicable to common shares, adjusted for certain notable items. These items include merger-related charges associated with completed and pending acquisitions, CECL Day 1 non-PCD provision expense, debt securities gains/losses, the expense associated with the distribution of excess pension assets, FDIC special assessment expense, gain on sale of Visa Class B restricted shares, contract termination charges, expenses related to the tragic April 10, 2023 event at our downtown Louisville location (“Louisville expenses”), and property optimization charges. Management believes excluding these items from net income per common share and net income applicable to common shares may be useful in assessing the Company's underlying operational performance since these items do not pertain to its core business operations and their exclusion may facilitate better comparability between periods. Management believes that excluding merger-related charges from these metrics may be useful to the Company, as well as analysts and investors, since these expenses can vary significantly based on the size, type, and structure of each acquisition. Additionally, management believes excluding these items from these metrics may enhance comparability for peer comparison purposes.

The taxable equivalent adjustment to net interest income and net interest margin recognizes the income tax savings when comparing taxable and tax-exempt assets. Interest income and yields on tax-exempt securities and loans are presented using the current federal income tax rate of 21%. Management believes that it is standard practice in the banking industry to present net interest income and net interest margin on a fully tax-equivalent basis and that it may enhance comparability for peer comparison purposes.

In management’s view, tangible common equity measures are capital adequacy metrics that may be meaningful to the Company, as well as users of the financial information, in assessing the Company’s use of equity and in facilitating comparisons with peers. These non-GAAP measures are valuable indicators of a financial institution’s capital strength since they eliminate intangible assets from shareholders’ equity and retain the effect of AOCI in shareholders’ equity.

Although intended to enhance understanding of the Company’s business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP. In addition, these non-GAAP financial measures may differ from those used by other financial institutions to assess their business and performance. See the previously provided tables and the following reconciliations in the “Non-GAAP Reconciliations” section for details on the calculation of these measures to the extent presented herein.

EXECUTIVE SUMMARY

Old National is the sixth largest commercial bank headquartered in the Midwest by asset size and ranks among the top 30 banking companies headquartered in the United States with consolidated assets of approximately $53 billion at June 30, 2024. The Company’s corporate headquarters and principal executive office is located in Evansville, Indiana with commercial and consumer banking operations headquartered in Chicago, Illinois. Through our wholly-owned banking subsidiary and non-bank affiliates, we provide a wide range of services primarily throughout the Midwest and Southeast regions of the United States. In addition to providing extensive services in consumer and commercial banking, Old National offers comprehensive wealth management and capital markets services.

Net income applicable to common shares for the second quarter of 2024 was $117.2 million, or $0.37 per diluted common share, compared to $116.3 million, or $0.40 per diluted common share, for the first quarter of 2024.

Results for the second quarter of 2024 were impacted by $19.4 million in pre-tax merger-related expenses primarily related to the April 1, 2024 acquisition of CapStar and $15.3 million of CECL Day 1 non-PCD provision expense related to the allowance for credit losses established on acquired non-PCD loans. Results for the first quarter of 2024 were impacted by a $13.3 million non-cash, pre-tax expense associated with the distribution of excess pension plan assets with the resolution of the legacy First Midwest defined benefit pension plan, $3.0 million for an FDIC special assessment, and $2.9 million of merger-related expenses. Excluding these items, net income applicable to common shares for the second quarter of 2024 was $144.1 million, or $0.46 per diluted common share on an adjusted basis1, compared to $130.8 million, or $0.45 per diluted common share on an adjusted basis1, for the first quarter of 2024.

Our results for the second quarter of 2024 reflected growth in total loans and deposits, increased net interest income, strong credit quality, and disciplined expense management.

Deposits:  Period-end total deposits increased $2.3 billion to $40.0 billion at June 30, 2024 compared to March 31, 2024, including $2.1 billion of end of period deposits assumed in the CapStar transaction. Excluding deposits assumed in the CapStar transaction, period-end total deposits were up 2.4% annualized.

Loans:  Our loan balances, excluding loans held-for-sale, increased $2.5 billion to $36.2 billion at June 30, 2024 compared to March 31, 2024, including $2.1 billion of period end loans acquired in the CapStar transaction. Excluding loans acquired in the CapStar transaction, period-end total loans were up 5.9% annualized.

Net Interest Income: Net interest income increased $32.0 million to $388.4 million compared to the first quarter of 2024 driven by CapStar, loan growth, and higher asset yields, partly offset by higher funding costs.

Provision for Credit Losses:  Provision for credit losses was $36.2 million; $20.9 million excluding $15.3 million of CECL Day 1 non-PCD provision expense related to the allowance for credit losses established on acquired non-PCD loans in the CapStar transaction, compared to $18.9 million for the first quarter of 2024, reflecting net charge-offs and loan growth, as well as economic factors.

Noninterest Income:  Noninterest income increased $9.7 million to $87.3 million compared to the first quarter of 2024 reflecting $6.5 million of CapStar revenue as well as higher wealth fees, mortgage fees, and capital markets income.

Noninterest Expense:  Noninterest expense increased $20.7 million compared to the first quarter of 2024.  For the second quarter of 2024, noninterest expense included $19.4 million of pre-tax merger-related expenses compared to a $13.3 million non-cash, pre-tax expense associated with the distribution of excess pension assets with the resolution of the legacy First Midwest plan, as well as pre-tax charges of $3.0 million for the FDIC special assessment and $2.9 million of merger-related and other expenses in the first quarter of 2024. Excluding these expenses, noninterest expense was $263.6 million for the second quarter of 2024, compared to $243.1 million for the first quarter of 2024, due primarily to operating costs associated with CapStar.

CAPSTAR TRANSACTION

On April 1, 2024, Old National completed its acquisition of CapStar, and its wholly-owned subsidiary, CapStar Bank. This partnership strengthens Old National’s Nashville, Tennessee presence and adds several new high-growth markets. At closing, CapStar had approximately $3.1 billion of total assets, $2.1 billion of total loans, and $2.6 billion of deposits. The consideration paid totaled $417.6 million and consisted of 24.0 million shares of Old National common stock. All system conversions related to the transaction were completed in early July of 2024.

Net Interest Income

Net interest income is the most significant component of our earnings, comprising 82% of revenues for the six months ended June 30, 2024. Net interest income and net interest margin are influenced by many factors, primarily the volume and mix of earning assets, funding sources, and interest rate fluctuations. Other factors include the level of accretion income on purchased loans, prepayment risk on mortgage and investment-related assets, and the composition and maturity of interest-earning assets and interest-bearing liabilities.

The Federal Reserve held its interest rates steady during the second quarter of 2024 and increased interest rates compared to June 30, 2023. The Federal Reserve’s Federal Funds Rate is currently in a target range of 5.25% to 5.50%, with the Effective Federal Funds Rate of 5.33% at June 30, 2024 compared to 5.08% at June 30, 2023. Management actively takes balance sheet restructuring, derivative, and deposit pricing actions to help mitigate interest rate risk. See the section of this Item 7 titled “Market Risk” for additional information regarding this risk.

Loans typically generate more interest income than investment securities with similar maturities. Funding from client deposits generally costs less than wholesale funding sources. Factors such as general economic activity, Federal Reserve monetary policy, and price volatility of competing alternative investments can also exert significant influence on our ability to optimize our mix of assets and funding, net interest income, and net interest margin.

Net interest income is the excess of interest received from interest-earning assets over interest paid on interest-bearing liabilities. For analytical purposes, net interest income is presented in the table that follows, adjusted to a taxable equivalent basis to reflect what our tax-exempt assets would need to yield in order to achieve the same after-tax yield as a taxable asset. We used the current federal statutory tax rate in effect of 21% for all periods. This

analysis portrays the income tax benefits related to tax-exempt assets and helps to facilitate a comparison between taxable and tax-exempt assets. Management believes that it is a standard practice in the banking industry to present net interest margin and net interest income on a fully taxable equivalent basis and that it may enhance comparability for peer comparison purposes for both management and investors.

The following tables presents the average balance sheet for each major asset and liability category, its related interest income and yield, or its expense and rate.

(1)The variance not solely due to rate or volume is allocated equally between the rate and volume variances.

(2)Interest income on investment securities includes taxable equivalent adjustments of $2.8 million and $5.6 million during the three and six months ended June 30, 2024, respectively, using the federal statutory rate in effect of 21%.

(3)Interest income on loans includes taxable equivalent adjustments of $3.5 million and $7.0 million during the three and six months ended June 30, 2024, respectively, using the federal statutory rate in effect of 21%.

The increase in net interest income for the three months ended June 30, 2024 when compared to the same period in 2023 was driven by the acquisition of CapStar and loan growth as well as higher rates on loans, partially offset by higher costs and balances of average interest-bearing liabilities. The decrease in net interest income for the six months ended June 30, 2024 when compared to the same period in 2023 was primarily due to higher costs and balances of average interest-bearing liabilities, partially offset by higher rates on loans as well as loan growth. Accretion income associated with acquired loans and borrowings totaled $11.6 million and $16.7 million for the three and six months ended June 30, 2024, respectively, compared to $6.6 million and $14.5 million for the same periods in 2023.

The decrease in the net interest margin on a fully taxable equivalent basis for the three and six months ended June 30, 2024 compared to the same periods in 2023 was primarily due to higher costs of interest-bearing liabilities, partially offset by higher yields on interest earning assets. The yield on interest earning assets increased 55 basis points and the cost of interest-bearing liabilities increased 96 basis points in the three months ended June 30, 2024 compared to the same quarter a year ago. The yield on interest earning assets increased 61 basis points and the cost of interest-bearing liabilities increased 112 basis points in the six months ended June 30, 2024 compared to the six months ended June 30, 2023. Accretion income represented 10 basis points and 7 basis points of the net interest margin in the three and six months ended June 30, 2024, respectively, compared to 6 basis points and 7 basis points in the three and six months ended June 30, 2023, respectively.

Average earning assets were $47.4 billion and $43.1 billion for the three months ended June 30, 2024 and 2023, respectively, an increase of $4.3 billion, or 10%, primarily due to loans and securities acquired in the CapStar transaction as well as strong loan growth. Average earning assets were $45.8 billion and $42.5 billion for the six months ended June 30, 2024 and 2023, respectively, an increase of $3.3 billion, or 8%, primarily due to loans and securities acquired in the CapStar transaction as well as strong loan growth.

60

Average loans, including loans held-for-sale, increased $3.8 billion and $2.9 billion for the three and six months ended June 30, 2024, respectively, when compared to the same periods in 2023 primarily due to loans acquired in the CapStar transaction as well as strong commercial real estate loan growth. Loans acquired in the CapStar transaction totaled $2.1 billion.

Average noninterest-bearing deposits decreased $1.2 billion while average interest-bearing deposits increased $6.2 billion for the three months ended June 30, 2024 when compared to the same period in 2023 reflecting a mix shift as a result of the current rate environment, deposits assumed in the CapStar transaction, and organic growth. Average noninterest-bearing deposits decreased $1.7 billion while average interest-bearing deposits increased $5.3 billion for the six months ended June 30, 2024 when compared to the same period in 2023 reflecting a mix shift as a result of the current rate environment, deposits assumed in the CapStar transaction, and organic growth. Deposits assumed in the CapStar transaction totaled $2.6 billion.

Provision for Credit Losses

The following table details the components of the provision for credit losses:

	Three Months Ended June 30,						%		Six Months Ended June 30,						%
(dollars in thousands)	2024			2023			Change		2024			2023			Change
Provision for credit losses on loans	$	36,745		$	11,936		207.9	%	$	60,598		$	23,405		158.9	%

Net charge-offs (recoveries) to average    loans	0.16		%	0.13		%	24.5	%	0.15		%	0.17		%	(10.8)

Total provision for credit losses on loans increased in the three and six months ended June 30, 2024 compared to the same periods in 2023 reflecting loan growth and macroeconomic factors. In addition, the provision for credit losses on loans in the three and six months ended June 30, 2024 included $15.3 million to establish an allowance for credit losses on non-PCD loans acquired in the CapStar transaction. Continued loan growth in future periods, a decline in our current level of recoveries, or an increase in charge-offs could result in an increase in provision expense. Additionally, provision expense may be volatile due to changes in CECL model assumptions of credit quality, macroeconomic factors and conditions, and loan composition, which drive the allowance for credit losses balance.

Noninterest Income

We generate revenues in the form of noninterest income through client fees, sales commissions, and gains and losses from our core banking franchise and other related businesses, such as wealth management, investment consulting, and investment products. The following table details the components in noninterest income:

	Three Months Ended June 30,				%		Six Months Ended June 30,				%

Total noninterest income	$	87,271	$	81,629	6.9	%	$	164,793	$	152,310	8.2	%

Noninterest income increased $5.6 million and $12.5 million for the three and six months ended June 30, 2024, respectively, compared to the same periods in 2023 primarily due to the acquisition of CapStar on April 1, 2024. In addition, noninterest income for the six months ended June 30, 2023 was impacted by $5.2 million of net losses on sales of debt securities.

Mortgage banking revenue increased $2.9 million and $4.0 million for the three and six months ended June 30, 2024, respectively, compared to the same periods in 2023 primarily due to higher mortgage originations and increased loan sales.

Capital markets income decreased $1.4 million and $5.5 million for the three and six months ended June 30, 2024, respectively, compared to the same periods in 2023 primarily due to lower levels of commercial real estate client interest rate swap fees.

Other income decreased $1.6 million for the three months ended June 30, 2024 compared to the same period in 2023 primarily due to lower gains on sales of other assets, partially offset by additional other income associated with the acquisition of CapStar.

Noninterest expense included $19.4 million and $2.4 million of merger-related expenses for the three months ended June 30, 2024 and 2023, respectively. In addition the three months ended June 30, 2023 included $3.4 million of expenses related to the Louisville tragedy and $0.2 million for property optimization charges. Excluding these

62

expenses, noninterest expense increased to $263.6 million for the three months ended June 30, 2024, compared to $240.6 million for the three months ended June 30, 2023. This increase was driven by the additional operating costs associated with the acquisition of CapStar, as well as higher salary and employee benefits reflective of merit increases.

Noninterest expense for the six months ended June 30, 2024 included $22.3 million of merger-related expenses, a $13.3 million non-cash, pre-tax expense associated with the distribution of excess pension assets with the resolution of the legacy First Midwest plan, and $3.0 million for the FDIC special assessment. Noninterest expense for the six months ended June 30, 2023 included $16.9 million of merger-related expenses, $3.4 million of expenses related to the Louisville tragedy, and $1.6 million for property optimization charges. Excluding these expenses, noninterest expense increased to $506.7 million for the six months ended June 30, 2024, compared to $475.4 million for the six months ended June 30, 2023. This increase was driven by the additional operating costs associated with the acquisition of CapStar, as well as higher salary and employee benefits reflective of merit increases.

Provision for Income Taxes

We record a provision for income taxes currently payable and for income taxes payable or benefits to be received in the future, which arise due to timing differences in the recognition of certain items for financial statement and income tax purposes. The major difference between the effective tax rate applied to our financial statement income and the federal statutory tax rate is caused by a tax benefit from our tax credit investments and interest on tax-exempt securities and loans. The effective tax rate was 22.5% and 21.9% for the three and six months ended June 30, 2024, respectively, compared to 23.4% and 22.8% for the three and six months ended June 30, 2023, respectively. The decreases in the effective tax rates for the three and six months ended June 30, 2024 when compared to the three and six months ended June 30, 2023 reflected decreases in pre-tax book income and state income taxes combined with an increase in tax credits. See Note 14 to the consolidated financial statements for additional information.. In accordance with ASC 740-270, Accounting for Interim Reporting, the provision for income taxes was recorded at June 30, 2024 based on the current estimate of the effective annual rate.

FINANCIAL CONDITION

Overview

At June 30, 2024, our assets were $53.1 billion, a $4.0 billion increase compared to assets of $49.1 billion at December 31, 2023. The increase was driven primarily by the acquisition of CapStar, as well as disciplined loan growth.

Earning Assets

Our earning assets are comprised of investment securities, portfolio loans, loans held-for-sale, money market investments, interest-earning accounts with the Federal Reserve, and equity securities. Earning assets were $47.6 billion at June 30, 2024, a $3.6 billion increase compared to earning assets of $43.9 billion at December 31, 2023.

Investment Securities

We classify the majority of our investment securities as available-for-sale to give management the flexibility to sell the securities prior to maturity based on fluctuating interest rates or changes in our funding requirements.

The investment securities portfolio, including equity securities, was $10.6 billion at June 30, 2024, compared to $10.2 billion at December 31, 2023. The increase was driven primarily by the acquisition of CapStar. Investment securities represented 22% of earning assets at June 30, 2024, compared to 23% at December 31, 2023. At June 30, 2024, we had no intent to sell any securities that were in an unrealized loss position nor is it expected that we would be required to sell the securities prior to their anticipated recovery.

The investment securities available-for-sale portfolio had net unrealized losses of $932.0 million and $869.5 million at June 30, 2024 and December 31, 2023, respectively. The investment securities held-to-maturity portfolio had net unrealized losses of $473.9 million and $412.3 million at June 30, 2024 and December 31, 2023, respectively.

The investment securities available-for-sale portfolio including securities hedges had an effective duration of 4.18 at June 30, 2024, compared to 4.24 at December 31, 2023. The total investment securities portfolio had an effective duration of 5.23 at June 30, 2024, compared to 5.35 at December 31, 2023. Effective duration represents the

63

percentage change in the fair value of the portfolio in response to a change in interest rates and is used to evaluate the portfolio’s price volatility at a single point in time. Generally, there is more uncertainty in interest rates over a longer average maturity, resulting in a higher duration percentage. The annualized average yields on investment securities, on a taxable equivalent basis, were 3.66% and 3.57% for the three and six months ended June 30, 2024, respectively, compared to 3.09% and 3.02% for the three and six months ended June 30, 2023, respectively.

Loan Portfolio

We lend to commercial and commercial real estate clients in many diverse industries including real estate rental and leasing, manufacturing, healthcare, wholesale trade, construction, and agriculture, among others. Old National manages concentrations of credit exposure by industry, product, geography, client relationship, and loan size. The following table presents the composition of the loan portfolio:

(dollars in thousands)	June 30, 2024		December 31, 2023		$ Change		% Change

Total loans	$	36,150,513	$	32,991,927	$	3,158,586	9.6	%

Commercial and Commercial Real Estate Loans

Commercial and commercial real estate loans are the largest classifications within earning assets, representing 55% of earning assets at both June 30, 2024, compared to 54% at December 31, 2023. The increase in commercial and commercial real estate loans at June 30, 2024 from December 31, 2023 was driven primarily by the acquisition of CapStar, as well as disciplined loan production that was well balanced across our market footprint and product lines.

The mix of properties securing the loans in our commercial real estate portfolio is balanced between owner-occupied and non-owner-occupied categories and is diverse in terms of type and geographic location, generally within the

65

Company’s primary market area. Approximately 27% of the commercial real estate portfolio is owner-occupied as of June 30, 2024, compared to 25% at December 31, 2023.

The Company actively reviews its broader loan portfolio in the normal course of business and has performed a targeted review of contractual maturities in its non-owner-occupied commercial real estate portfolio as part of its response to current market conditions to identify exposure to credit risk associated with renewals. At June 30, 2024, the Company held $372.3 million of non-owner-occupied commercial real estate loans, or 1% of total loans, that mature within 18 months with an interest rate below 4%.

Residential Real Estate Loans

At June 30, 2024, residential real estate loans held in our loan portfolio were $6.9 billion, an increase of $195.5 million compared to December 31, 2023 driven primarily by the acquisition of CapStar. Changes in interest rates may impact the number of refinancings and new originations of residential real estate loans. If interest rates decrease in the future, there may be an increase in refinancings and new originations of residential real estate loans. Conversely, future increases in interest rates may result in a decline in the level of refinancings and new originations of residential real estate loans.

Consumer Loans

Consumer loans, including automobile loans, personal, and home equity loans and lines of credit, increased $266.3 million to $2.9 billion at June 30, 2024 compared to December 31, 2023 driven primarily by the acquisition of CapStar.

Goodwill and Other Intangible Assets

Goodwill and other intangible assets at June 30, 2024 totaled $2.3 billion, an increase of $205.2 million compared to December 31, 2023 as a result of goodwill and other intangible assets recorded with the acquisition of CapStar.

The increase in total deposits was primarily due to deposits assumed in the CapStar transaction. We use wholesale funding to augment deposit funding and to help maintain our desired interest rate risk position. Wholesale funding as a percentage of total funding was 13% at both June 30, 2024 and December 31, 2023.

Capital 

Shareholders’ equity totaled $6.1 billion at June 30, 2024 and $5.6 billion at December 31, 2023. Old National issued 24.0 million shares of Common Stock in conjunction with the acquisition of CapStar on April 1, 2024 totaling $417.6 million in shareholders’ equity. Retained earnings were partially offset by dividends and changes in unrealized gains (losses) on available-for-sale investment securities during the six months ended June 30, 2024.

Capital Adequacy

Old National and the banking industry are subject to various regulatory capital requirements administered by the federal banking agencies. At June 30, 2024, Old National and its bank subsidiary exceeded the regulatory minimums and Old National Bank met the regulatory definition of “well-capitalized” based on the most recent regulatory definition.

Old National’s consolidated capital position remains strong as evidenced by the following key industry ratios. 

	Regulatory Guidelines Minimum		Prompt Corrective Action "Well Capitalized" Guidelines		June 30, 2024		December 31, 2023
Tier 1 capital to total average assets (leverage    ratio)	4.00	%	N/A	%	8.90	%	8.83	%
Common equity Tier 1 capital to risk-weighted    total assets	7.00		N/A		10.73		10.70

During 2020, the OCC, the Board of Governors of the Federal Reserve System, and the FDIC issued final rules to delay the estimated impact on regulatory capital stemming from the implementation of CECL. The final rules provide banking organizations the option to delay for two years an estimate of CECL’s effect on regulatory capital, relative to the incurred loss methodology’s effect on regulatory capital, followed by a three-year transition period (five-year transition option). Old National adopted the capital transition relief over the permissible five-year period.

Management views stress testing as an integral part of the Company’s risk management and strategic planning activities. Old National performs stress testing periodically throughout the year. The primary objective of the stress test is to ensure that Old National has a robust, forward-looking stress testing process and maintains sufficient capital to continue operations throughout times of economic and financial stress. Management also uses the stress testing framework to evaluate decisions relating to pricing, loan concentrations, capital deployment, and mergers and acquisitions to ensure that strategic decisions align with Old National’s risk appetite statement. Old National’s stress testing process incorporates key risks that include strategic, market, liquidity, credit, operational, regulatory, compliance, legal, and reputational risks. Old National’s stress testing policy outlines steps that will be taken if stress test results do not meet internal thresholds under severely adverse economic scenarios.

RISK MANAGEMENT

Overview

Old National has adopted a Risk Appetite Statement to enable our Board of Directors, Enterprise Risk Committee of our Board, Executive Leadership Team, and Senior Management to better assess, understand, monitor, and mitigate Old National’s risks. The Risk Appetite Statement addresses the following major risks: strategic, market, liquidity, credit, operational, talent management, compliance and regulatory, legal, and reputational. Our Chief Risk Officer

67

provides quarterly reports to the Board’s Enterprise Risk Committee on various risk topics. The following discussion addresses certain of these major risks including credit, market, and liquidity. Discussion of operational, compliance and regulatory, legal, strategic, talent management, and reputational risks is provided in the section entitled “Risk Factors” in the Company’s 2023 Annual Report on Form 10-K.

Credit Risk

Credit risk represents the risk of loss arising from an obligor’s inability or failure to meet contractual payment or performance terms. Our primary credit risks result from our investment and lending activities.

Asset Quality

We lend to commercial and commercial real estate clients in many diverse industries including, among others, real estate rental and leasing, manufacturing, healthcare, wholesale trade, construction, and agriculture. Old National manages concentrations of credit exposure by industry, product, geography, client relationship, and loan size. At June 30, 2024, our average commercial loan size was approximately $610,000 and our average commercial real estate loan size was approximately $1,330,000. In addition, while loans to lessors of residential and non-residential real estate exceed 10% of total loans, no individual sub-segment category within those broader categories reaches the 10% threshold. At June 30, 2024, we had minimal exposure to foreign borrowers and no sovereign debt. Our policy is to concentrate our lending activity in the geographic market areas we serve, primarily in the Midwest and Southeast regions of the United States.

Under-performing assets increased to $353.7 million at June 30, 2024, compared to $285.2 million at December 31, 2023. Under-performing assets as a percentage of total loans at June 30, 2024 were 0.98%, a 12 basis point increase from 0.86% at December 31, 2023.

Nonaccrual loans increased $65.4 million from December 31, 2023 to June 30, 2024 reflecting the migration of certain non-owner-occupied commercial real estate loans as they progress to resolution as well as $17.2 million of nonaccrual loans acquired in the CapStar acquisition. As a percentage of nonaccrual loans, the allowance for credit losses on loans was 107.69% at June 30, 2024, compared to 111.93% at December 31, 2023.

Total criticized and classified assets were $2.2 billion at June 30, 2024, an increase of $447.0 million from December 31, 2023 primarily due to higher criticized and classified commercial real estate loans as well as $73.1 million of criticized and classified loans related to the CapStar acquisition. Other classified assets include investment securities that fell below investment grade rating totaling $60.8 million at June 30, 2024, compared to $48.9 million at December 31, 2023.

Allowance for Credit Losses on Loans and Unfunded Commitments

Net charge-offs on loans totaled $14.0 million during the three months ended June 30, 2024, compared to $10.1 million for the same period in 2023. Annualized, net charge-offs to average loans were 0.16% for the three months ended June 30, 2024, compared to 0.13% for the same period in 2023. The three months ended June 30, 2024 included net charge-offs on PCD loans totaling $4.2 million, or 0.05% on an annualized basis of average loans, compared to net charge-offs on PCD loans totaling $5.4 million, or 0.07% on an annualized basis of average loans for the three months ended June 30, 2023. Net charge-offs on loans totaled $25.8 million during the six months ended June 30, 2024, compared to $26.5 million for the same period in 2023. Annualized, net charge-offs to average loans were 0.15% for the six months ended June 30, 2024, compared to 0.17% for the same period in 2023. The six months ended June 30, 2024 included net charge-offs on PCD loans totaling $9.9 million, or 0.06% on an annualized basis of average loans, compared to net charge-offs on PCD loans totaling $17.8 million, or 0.11% on an annualized basis of average loans for the six months ended June 30, 2023.

Credit quality within the loans held for investment portfolio is continuously monitored by management and is reflected within the allowance for credit losses on loans. The allowance for credit losses is an estimate of expected losses inherent within the Company’s loans held for investment portfolio. Credit quality is assessed and monitored by evaluating various attributes and the results of those evaluations are utilized in underwriting new loans and in our process for estimating expected credit losses. Expected credit loss inherent in non-cancelable off-balance-sheet credit exposures is accounted for as a separate liability included in other liabilities on the balance sheet. The allowance for credit losses on loans held for investment and unfunded loan commitments is adjusted by a credit loss expense, which is reported in earnings, and reduced by the charge-off of loan amounts, net of recoveries. Accrued interest receivable is excluded from the estimate of credit losses.

The allowance for credit loss estimation process involves procedures to consider the unique characteristics of our loan portfolio segments. These segments are further disaggregated into loan classes based on the level at which credit risk of the loan is monitored. When computing the level of expected credit losses, credit loss assumptions are estimated using a model that categorizes loan pools based on loss history, delinquency status, and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods, evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense in those future periods.

The allowance level is influenced by loan volumes, loan AQR migration or delinquency status, changes in historical loss experience, and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The methodology for estimating the amount of expected credit losses reported in the allowance for credit losses on loans has two basic components: first, an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans; and second, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics.

The allowance for credit losses on loans was $366.3 million at June 30, 2024, compared to $307.6 million at December 31, 2023. The increase reflects $23.9 million of allowance for credit losses on acquired PCD loans established through acquisition accounting adjustments on or after the CapStar acquisition date. In addition, the provision for credit losses on loans in the three and six months ended June 30, 2024 included $15.3 million to establish an allowance for credit losses on non-PCD loans acquired in the CapStar transaction. Continued loan growth in future periods, a decline in our current level of recoveries, or an increase in charge-offs could result in an increase in provision expense. Additionally, provision expense may be volatile due to changes in CECL model assumptions of credit quality, macroeconomic factors and conditions, and loan composition, which drive the allowance for credit losses balance.

We maintain an allowance for credit losses on unfunded loan commitments to provide for the risk of loss inherent in these arrangements. The allowance is computed using a methodology similar to that used to determine the allowance for credit losses on loans, modified to take into account the probability of a drawdown on the commitment. The allowance for credit losses on unfunded loan commitments is classified as a liability account on the balance sheet within accrued expenses and other liabilities, while the corresponding provision for unfunded loan commitments is included in the provision for credit losses. The allowance for credit losses on unfunded loan commitments totaled $25.7 million at June 30, 2024, compared to $31.2 million at December 31, 2023. We increased the allowance for

69

credit losses on unfunded loans commitments by $1.8 million in the three and six months ended June 30, 2024 as a result of the CapStar transaction.

See the section entitled “Risk Factors” in the Company’s 2023 Annual Report on Form 10-K for further discussion of our credit risk.

Market Risk

Market risk is the risk that the estimated fair value of our assets, liabilities, and derivative financial instruments will decline as a result of changes in interest rates or financial market volatility, or that our net income will be significantly reduced by interest rate changes.

The objective of our interest rate management process is to maximize net interest income while operating within acceptable limits established for interest rate risk and maintaining adequate levels of funding and liquidity.

Potential cash flows, sales, or replacement value of many of our assets and liabilities, especially those that earn or pay interest, are sensitive to changes in the general level of interest rates. This interest rate risk arises primarily from our normal business activities of gathering deposits and extending loans. Many factors affect our exposure to changes in interest rates, such as general economic and financial conditions, client preferences, historical pricing relationships, and re-pricing characteristics of financial instruments. Our earnings can also be affected by the monetary and fiscal policies of the U.S. Government and its agencies, particularly the Federal Reserve.

In managing interest rate risk, we establish guidelines for asset and liability management, including measurement of short and long-term sensitivities to changes in interest rates, which are reviewed with the Enterprise Risk Committee of our Board of Directors. Based on the results of our analysis, we may use different techniques to manage changing trends in interest rates including:

•adjusting balance sheet mix or altering interest rate characteristics of assets and liabilities;

•changing product pricing strategies;

•modifying characteristics of the investment securities portfolio; or

•using derivative financial instruments, to a limited degree.

A key element in our ongoing process is to measure and monitor interest rate risk using a model to quantify the likely impact of changing interest rates on Old National’s results of operations. The model quantifies the effects of various possible interest rate scenarios on projected net interest income. The model measures the impact on net interest income relative to a base case scenario over a two-year cumulative horizon resulting from an immediate change in interest rates using multiple rate scenarios. The base case scenario assumes that the balance sheet and interest rates are held at current levels. The model shows our projected net interest income sensitivity based on interest rate changes only and does not consider other forecast assumptions. Due to the dynamics of future interest rate expectations, we also measure and monitor interest rate risk using the forward curve, which may be a more probable scenario of our interest rate exposure. The forward curve represents the relationship between the price of forward contracts and the time to maturity of the forward contracts at a point in time. Presentation of the forward curve model is included in the following table as of June 30, 2024.

Our projected net interest income increased year over year due to loan growth and rising interest rates.

A key element in the measurement and modeling of interest rate risk is the re-pricing assumptions of our transaction deposit accounts, which have no contractual maturity dates. Because the models are driven by expected behavior in various interest rate scenarios and many factors besides market interest rates affect our net interest income, we recognize that model outputs are not guarantees of actual results. For this reason, we model many different combinations of interest rates and balance sheet assumptions to understand our overall sensitivity to market interest rate changes, including shocks, ramps, yield curve flattening, yield curve steepening, as well as forecasts of likely interest rate scenarios tested.

We use cash flow and fair value hedges, primarily interest rate swaps, collars, and floors, to mitigate interest rate risk. Derivatives designated as hedging instruments were in a net liability position with a fair value loss of $13.6 million at June 30, 2024, compared to a net asset position with a fair value gain of $4.5 million at

71

December 31, 2023. See Note 15 to the consolidated financial statements for further discussion of derivative financial instruments.

Liquidity Risk

Liquidity risk arises from the possibility that we may not be able to satisfy current or future financial commitments or may become unduly reliant on alternative funding sources. We establish liquidity risk guidelines that we review with the Enterprise Risk Committee of our Board of Directors and monitor through our Asset/Liability Executive Management Committee. The objective of liquidity management is to ensure we have the ability to fund balance sheet growth and meet deposit and debt obligations in a timely and cost-effective manner. Management monitors liquidity through a regular review of asset and liability maturities, funding sources, and loan and deposit forecasts. We maintain strategic and contingency liquidity plans to ensure sufficient available funding to satisfy requirements for balance sheet growth, to properly manage capital markets’ funding sources, and to address unexpected liquidity requirements. On May 31, 2023, we filed an automatic shelf registration statement with the SEC that permits us to issue an unspecified amount of debt or equity securities.

Loan repayments and maturing investment securities are a relatively predictable source of funds. However, deposit flows, calls of investment securities, and prepayments of loans and mortgage-related securities are not as predictable as they are strongly influenced by interest rates, events at other banking organizations, the housing market, general and local economic conditions, and competition in the marketplace. We continually monitor marketplace trends to identify patterns that might improve the predictability of the timing of deposit flows or asset prepayments.

A maturity schedule for Old National Bank’s time deposits is shown in the following table at June 30, 2024.

Total available funds	$	436,277	$	13,251,213

* Based on collateral pledged

Old National Bancorp has routine funding requirements consisting primarily of operating expenses, dividends to shareholders, debt service, net derivative cash flows, and funds used for acquisitions. Old National Bancorp can obtain funding to meet its obligations from dividends and management fees collected from its subsidiaries, operating line of credit, and through the issuance of debt securities. Additionally, Old National Bancorp has a shelf registration in place with the SEC permitting ready access to the public debt and equity markets. At June 30, 2024, Old National Bancorp’s other borrowings outstanding were $507.3 million. Management believes the Company has the ability to generate and obtain adequate amounts of liquidity to meet its requirements in the short-term and the long-term.

Federal banking laws regulate the amount of dividends that may be paid by Old National Bank to Old National Bancorp on an unconsolidated basis without obtaining prior regulatory approval. Prior regulatory approval is required if dividends to be declared in any year would exceed net earnings of the current year plus retained net profits for the preceding two years. Prior regulatory approval to pay dividends was not required in 2023 and is not currently required.

CRITICAL ACCOUNTING ESTIMATES

Our most significant accounting policies are described in Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2023. Certain of these accounting policies require management to use significant judgment and estimates, which can have a material impact on the carrying value of certain assets and liabilities. We consider these policies to be our critical accounting estimates. The judgment and assumptions made are based upon historical experience, future forecasts, or other factors that management believes to be reasonable under the circumstances. Because of the nature of the judgment and assumptions, actual results could differ from estimates, which could have a material effect on our financial condition and results of operations.

For additional information regarding critical accounting estimates, see the section titled “Critical Accounting Estimates” included in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2023. There have been no material changes in the Company’s application of critical accounting estimates since December 31, 2023.

ITEM 4.  CONTROLS AND PROCEDURES

Conclusion Regarding the Effectiveness of Disclosure Controls and Procedures

Evaluation of Disclosure Controls and Procedures. Old National’s principal executive officer and principal financial officer have concluded that Old National’s disclosure controls and procedures (as defined in Exchange Act Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended), based on their evaluation of these controls and procedures as of the end of the period covered by this quarterly report on Form 10-Q, are effective at the reasonable assurance level as discussed below to ensure that information required to be disclosed by Old National in the reports it files under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and that such information is accumulated and communicated to Old National’s management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Limitations on the Effectiveness of Controls. Management, including the principal executive officer and principal financial officer, does not expect that Old National’s disclosure controls and internal controls will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls.

The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be only reasonable assurance that any design will succeed in achieving its stated goals under all potential future conditions. Over time, the system of controls may become inadequate because of changes in conditions or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Changes in Internal Control over Financial Reporting. There were no changes in Old National’s internal control over financial reporting that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, Old National’s internal control over financial reporting.

Basis of Presentation

BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Old National Bancorp and its wholly-owned subsidiaries (hereinafter collectively referred to as “Old National”) and have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. Such principles require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosures of contingent assets and liabilities at the date of the financial statements and amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, the consolidated financial statements contain all the normal and recurring adjustments necessary for a fair statement of the financial position of Old National as of June 30, 2024 and December 31, 2023, and the results of its operations for the three and six months ended June 30, 2024 and 2023. Interim results do not necessarily represent annual results. Certain information and disclosures normally included in notes to consolidated annual financial statements prepared in accordance with GAAP have been condensed or omitted in this Quarterly Report on Form 10-Q pursuant to SEC rules and regulations. These financial statements should be read in conjunction with Old National’s Annual Report on Form 10-K for the year ended December 31, 2023.

All intercompany transactions and balances have been eliminated. Certain prior year amounts have been reclassified to conform to the current presentation. Such reclassifications had no effect on prior period net income or shareholders’ equity and were insignificant amounts.

Accounting Changes and Error Corrections [Abstract]

Recent Accounting Pronouncements

RECENT ACCOUNTING PRONOUNCEMENTS

Accounting Guidance Adopted in 2024

FASB ASC 820 – In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, to 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. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The adoption of this guidance on January 1, 2024 did not have a material impact on the consolidated financial statements.

FASB ASC 323 – In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, which allows 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 ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this guidance on a modified retrospective basis on January 1, 2024 did not have a material impact on the consolidated financial statements.

FASB ASC 848 – In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from LIBOR or other interbank offered rate on financial reporting. The guidance is applicable only to contracts or hedge accounting relationships that reference LIBOR or another reference rate expected to be discontinued.

In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which defers the sunset date of relief provisions within Topic 848 from December 31, 2022 to December 31, 2024. The objective of the guidance in Topic 848 is to provide relief during the transition period.

The amendments in this ASU are effective March 12, 2020 through December 31, 2024. As of June 30, 2024, substantially all of the Company’s LIBOR exposure was addressed and remaining LIBOR-based contracts are expected to transition to alternate reference rates at their next index reset dates. Old National believes the adoption of this guidance on activities subsequent to June 30, 2024 will not have a material impact on the consolidated financial statements.

Accounting Guidance Pending Adoption 

FASB ASC 280 – In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments are intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. A public entity should apply the amendments retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. This 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. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

FASB ASC 740 – In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. Among other things, these amendments require that public business entities on an annual basis disclose additional information in specified categories with respect to the reconciliation of the effective tax rate to the statutory rate for federal, state, and foreign income taxes. It also requires greater detail about individual reconciling items in the rate reconciliation to the extent the impact of those items exceeds a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (loss) by the applicable statutory income tax rate). In addition, the ASU requires information pertaining to taxes paid (net of refunds received) to be disaggregated for federal, state, and foreign taxes and further disaggregated for specific jurisdictions to the extent the related amounts are equal to or greater than 5 percent of total income taxes paid (net of refunds received). The amendments in this ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

CapStar Financial Holdings, Inc.

On April 1, 2024, Old National completed its acquisition of CapStar Financial Holdings, Inc. (“CapStar”) and its wholly-owned subsidiary, CapStar Bank, in an all-stock transaction. This partnership strengthens Old National’s Nashville, Tennessee presence and adds several new high-growth markets. Pursuant to the terms of the merger agreement, each outstanding share of CapStar common stock was converted into the right to receive 1.155 shares of Old National common stock plus cash in lieu of fractional shares. All system conversions related to the transaction were completed in early July of 2024.

The assets acquired and liabilities assumed, both intangible and tangible, were recorded at their estimated fair values as of the merger date and have been accounted for under the acquisition method of accounting. The following table presents the preliminary valuation of the assets acquired and liabilities assumed and the fair value of consideration as of the merger date:

Other intangible assets acquired included core deposit intangibles. The estimated fair value of the core deposit intangible was $46.1 million and is being amortized over an estimated useful life of 10 years.

The fair value of PCD assets was $613.5 million on the date of merger. The gross contractual amounts receivable relating to the PCD assets was $679.3 million. Old National estimates, on the date of the merger, that $23.9 million of the contractual cash flows specific to the PCD assets will not be collected.

Transaction costs primarily associated with the CapStar merger have been expensed for the three and six months ended June 30, 2024 totaling $19.4 million and $22.3 million, respectively, and additional transaction and integration costs will be expensed in future periods as incurred.

Earnings Per Share [Abstract]

Net Income Per Common Share

NET INCOME PER COMMON SHARE

Basic and diluted net income per common share are calculated using the two-class method. Net income applicable to common shares is divided by the weighted-average number of common shares outstanding during the period. Adjustments to the weighted-average number of common shares outstanding are made only when such adjustments will dilute net income per common share. Net income applicable to common shares is then divided by the weighted-average number of common shares and common share equivalents during the period.

The following table presents the calculation of basic and diluted net income per common share:

The unrecognized losses on held-to-maturity investment securities presented in the table above do not include unrecognized losses on securities that were transferred from available-for-sale to held-to-maturity totaling $118.9 million at June 30, 2024 and $127.6 million at December 31, 2023. These unrecognized losses are included as a separate component of shareholders’ equity and are being amortized over the remaining term of the securities.

No allowance for credit losses on available-for-sale debt securities was needed at June 30, 2024 or December 31, 2023.

An allowance on held-to-maturity debt securities is maintained for certain municipal bonds to account for expected lifetime credit losses. Substantially all of the U.S. government-sponsored entities and agencies and agency mortgage-backed securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major credit rating agencies, and have a long history of no credit losses. Therefore, for those securities, we do not record expected credit losses. The allowance for credit losses on held-to-maturity debt securities was $0.2 million at June 30, 2024 and December 31, 2023. Accrued interest receivable on the securities portfolio is excluded from the estimate of credit losses and totaled $53.0 million at June 30, 2024 and $50.3 million at December 31, 2023.

At June 30, 2024, Old National’s securities portfolio consisted of 3,039 securities, 2,792 of which were in an unrealized loss position. The unrealized losses attributable to our U.S. Treasury, U.S. government-sponsored entities and agencies, agency mortgage-backed securities, states and political subdivisions, and other securities are the result of fluctuations in interest rates and market movements. Old National’s pooled trust preferred securities are evaluated using collateral-specific assumptions to estimate the expected future interest and principal cash flows. At June 30, 2024, we had no intent to sell any securities that were in an unrealized loss position nor is it expected that we would be required to sell the securities prior to their anticipated recovery.

Old National’s pooled trust preferred securities have experienced credit defaults. However, we believe that the value of the instruments lies in the full and timely interest payments that will be received through maturity, the steady amortization that will be experienced until maturity, and the full return of principal by the final maturity of the collateralized debt obligations. Old National did not recognize any losses on these securities for the six months ended June 30, 2024 or 2023.

Equity Securities

Equity securities consist of mutual funds for Community Reinvestment Act qualified investments and diversified investment securities held in a grantor trust for participants in the Company’s nonqualified deferred compensation plan. Old National’s equity securities with readily determinable fair values totaled $85.5 million at June 30, 2024 and $80.4 million at December 31, 2023. There were losses on equity securities of $0.4 million during the three months ended June 30, 2024 and $0.1 million during the six months ended June 30, 2024, compared to gains of $0.1

million during the three months ended June 30, 2023 and losses of $0.7 million during the six months ended June 30, 2023.

Alternative Investments

Old National has alternative investments without readily determinable fair values that are included in other assets totaling $514.8 million at June 30, 2024, consisting of $274.9 million of illiquid investments in partnerships, limited liability companies, and other ownership interests that support affordable housing and $239.9 million of economic development and community revitalization initiatives in low-to-moderate income neighborhoods. These alternative investments totaled $449.3 million at December 31, 2023. There have been no impairments or adjustments on equity securities without readily determinable fair values, except for amortization of tax credit investments in the six months ended June 30, 2024 and 2023. See Note 9 to the consolidated financial statements for detail regarding these investments.

Loans and Allowance for Credit Losses

Loans and Allowance for Credit Losses

LOANS AND ALLOWANCE FOR CREDIT LOSSES

Loans

Old National’s loans consist primarily of loans made to consumers and commercial clients in many diverse industries, including real estate rental and leasing, manufacturing, healthcare, wholesale trade, construction, and agriculture, among others. Most of Old National’s lending activity occurs within our principal geographic markets in the Midwest and Southeast regions of the United States. Old National manages concentrations of credit exposure by industry, product, geography, client relationship, and loan size.

Old National has loan participations, which qualify as participating interests, with other financial institutions. At June 30, 2024, these loans totaled $3.5 billion, of which $1.6 billion had been sold to other financial institutions and $1.9 billion was retained by Old National. The loan participations convey proportionate ownership rights with equal priority to each participating interest holder; involve no recourse (other than ordinary representations and warranties) to, or subordination by, any participating interest holder; all cash flows are divided among the participating interest holders in proportion to each holder’s share of ownership; and no holder has the right to pledge the entire financial asset unless all participating interest holders agree.

The loan categories used to monitor and analyze interest income and yields are different than the portfolio segments used to determine the allowance for credit losses on loans. The allowance for credit losses was calculated by pooling loans of similar credit risk characteristics and credit monitoring procedures. The four loan portfolios used to monitor and analyze interest income and yields – commercial, commercial real estate, residential real estate, and consumer – are reclassified into seven segments of loans – commercial, commercial real estate, BBCC, residential real estate, indirect, direct, and home equity for purposes of determining the allowance for credit losses on loans. The commercial and commercial real estate loan categories shown on the balance sheet include the same pool of loans as the commercial, commercial real estate, and BBCC portfolio segments. The consumer loan category shown on the balance sheet is comprised of the same loans in the indirect, direct, and home equity portfolio segments. The portfolio segment reclassifications follow:

(1)Includes direct finance leases of $157.2 million at June 30, 2024 and $169.7 million at December 31, 2023.

(2)    Includes unearned income of $199.7 million at June 30, 2024 and $93.7 million at December 31, 2023.

The risk characteristics of each loan portfolio segment are as follows:

Commercial

Commercial loans are classified primarily on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets such as accounts receivable or inventory and may incorporate a personal guarantee; however, some loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its clients.

Commercial Real Estate

Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts, and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted

on the property securing the loan. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. The properties securing Old National’s commercial real estate portfolio are diverse in terms of type and geographic location. Management monitors and evaluates commercial real estate loans based on collateral, geography, and risk grade criteria. In addition, management tracks the level of owner-occupied commercial real estate loans versus non-owner-occupied loans.

Included with commercial real estate are construction loans, which are underwritten utilizing independent appraisal reviews, sensitivity analysis of absorption and lease rates, financial analysis of the developers and property owners, and feasibility studies, if available. Construction loans are generally based on estimates of costs and value associated with the complete project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders (including Old National), sales of developed property, or an interim loan commitment from Old National until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions, and the availability of long-term financing.

At 256%, Old National Bank’s applicable investor commercial real estate loans as a percentage of its Tier 1 capital plus the allowance for credit losses attributable to loans and leases remained below the regulatory guideline limit of 300% at June 30, 2024.

BBCC

BBCC loans are typically granted to small businesses with gross revenues of less than $5 million and aggregate debt of less than $1 million. Old National has established minimum debt service coverage ratios, minimum FICO scores for owners and guarantors, and the ability to show relatively stable earnings as criteria to help mitigate risk. Repayment of these loans depends on the personal income of the borrowers and the cash flows of the business. These factors can be affected by such changes as economic conditions and unemployment levels.

Residential

With respect to residential loans that are secured by 1 - 4 family residences and are generally owner occupied, Old National typically establishes a maximum loan-to-value ratio and generally requires private mortgage insurance if that ratio is exceeded. Repayment of these loans is primarily dependent on the personal income 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. Portfolio risk is mitigated by the fact that the loans are of smaller individual amounts and spread over a large number of borrowers.

Indirect

Indirect loans are secured by automobile collateral, generally new and used cars and trucks from auto dealers that operate within our footprint. Old National typically mitigates the risk of indirect loans by establishing minimum FICO scores, maximum loan-to-value ratios, and maximum debt-to-income ratios. Repayment of these loans depends largely on the personal income of the borrowers, which can be affected by changes in economic conditions such as unemployment levels. Portfolio risk is mitigated by the fact that the loans are of smaller amounts spread over many borrowers and ongoing reviews of dealer relationships.

Direct

Direct loans are typically secured by collateral such as auto or real estate or are unsecured. Old National has established underwriting standards such as minimum FICO scores, maximum loan-to-value ratios, and maximum debt-to-income ratios. Repayment of these loans depends largely on the personal income of the borrowers, which can be affected by changes in economic conditions such as unemployment levels. Portfolio risk is mitigated by the fact that the loans are of smaller amounts spread over many borrowers.

Home Equity

Home equity loans are generally secured by 1-4 family residences that are owner-occupied. Old National has established underwriting standards such as minimum FICO scores, maximum loan-to-value ratios, and maximum debt-to-income ratios. Repayment of these loans depends largely on the personal income of the borrowers, which can be affected by changes in economic conditions such as unemployment levels. Portfolio risk is mitigated by the

fact that the loans are of smaller amounts spread over many borrowers, along with monitoring of updated borrower credit scores.

Allowance for Credit Losses

Loans

Credit loss assumptions used when computing the level of expected credit losses are estimated using a model that categorizes loan pools based on loss history, delinquency status, and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. The base forecast scenario considers unemployment, gross domestic product, and the BBB ratio (BBB spread to the 10-year U.S. Treasury rate). In addition to the quantitative inputs, several qualitative factors are considered. These factors include the risk that unemployment, gross domestic product, housing product index, and the BBB ratio prove to be more severe and/or prolonged than our baseline forecast due to a variety of factors including monetary actions to control inflation, recent instability in the banking sector, global military conflicts, and global supply chain issues. Old National’s activity in the allowance for credit losses on loans by portfolio segment was as follows:

In addition, the provision for credit losses on loans in the three and six months ended June 30, 2024 included $15.3 million to establish an allowance for credit losses on non-PCD loans acquired in the CapStar transaction. Accrued interest receivable on loans is excluded from the estimate of credit losses and totaled $181.9 million at June 30, 2024, compared to $169.8 million at December 31, 2023.

Unfunded Loan Commitments

Old National maintains an allowance for credit losses on unfunded loan commitments to provide for the risk of loss inherent in these arrangements. The allowance is computed using a methodology similar to that used to determine the allowance for credit losses on loans, modified to take into account the probability of a drawdown on the commitment. The allowance for credit losses on unfunded loan commitments is classified as a liability account on the balance sheet within accrued expenses and other liabilities, while the corresponding provision for unfunded loan commitments is included in the provision for credit losses. Old National’s activity in the allowance for credit losses on unfunded loan commitments was as follows:

	Three Months Ended June 30,				Six Months Ended June 30,

Credit Quality

Old National’s management monitors the credit quality of its loans on an ongoing basis with the AQR for commercial loans reviewed annually or at renewal and the performance of its residential and consumer loans based upon the accrual status refreshed at least quarterly. Internally, management assigns an AQR to each non-homogeneous commercial, commercial real estate, and BBCC loan in the portfolio. The primary determinants of the AQR are the reliability of the primary source of repayment and the past, present, and projected financial condition of the borrower. The AQR will also consider current industry conditions. Major factors used in determining the AQR can vary based on the nature of the loan, but commonly include factors such as debt service coverage, internal cash flow, liquidity, leverage, operating performance, debt burden, FICO scores, occupancy, interest rate sensitivity, and expense burden. Old National uses the following definitions for risk ratings:

Special Mention. Loans categorized as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date.

Classified – Substandard. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected.

Classified – Nonaccrual. Loans classified as nonaccrual have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection in full, on the basis of currently existing facts, conditions, and values, in doubt.

Classified – Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as nonaccrual, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Pass rated loans are those loans that are other than special mention, classified – substandard, classified – nonaccrual, or classified – doubtful.

Nonaccrual and Past Due Loans

Old National does not record interest on nonaccrual loans until principal is recovered. For all loan classes, a loan is generally placed on nonaccrual status when principal or interest becomes 90 days past due unless it is well secured and in the process of collection, or earlier when concern exists as to the ultimate collectability of principal or interest. Interest accrued but not received is reversed against earnings. Cash interest received on these loans is applied to the principal balance until the principal is recovered or until the loan returns to accrual status. Loans may

be returned to accrual status when all the principal and interest amounts contractually due are brought current, remain current for a prescribed period, and future payments are reasonably assured.

The following table presents the aging of the amortized cost basis in past due loans by class of loans:

Interest income recognized on nonaccrual loans was insignificant during the three and six months ended June 30, 2024 and 2023.

When management determines that foreclosure is probable, expected credit losses for collateral dependent loans are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. A loan is considered collateral dependent when the borrower is experiencing financial difficulty, and the loan is expected to be repaid substantially through the operation or sale of the collateral. The class of loan represents the primary collateral type associated with the loan. Significant quarter-over-quarter changes are reflective of changes in nonaccrual status and not necessarily associated with credit quality indicators like appraisal value. The following table presents the amortized cost basis of collateral dependent loans by class of loan:

Financial Difficulty Modifications

Occasionally, Old National modifies loans to borrowers experiencing financial difficulty in the form of principal forgiveness, term extension, an other-than-insignificant payment delay, or interest rate reduction (or a combination thereof). When principal forgiveness is provided, the amount of forgiveness is charged-off against the allowance for credit losses on loans.

The following table presents the amortized cost basis of financial difficulty modifications that were modified for borrowers experiencing financial difficulty, by class of loans and type of modification:

(dollars in thousands)	Term Extension		Total Class of Loans

During the three and six months ended June 30, 2024, there were payment defaults on $27.0 million of loans to borrowers whose loans were modified due to financial difficulties within the previous twelve months. The payment defaults did not materially impact the allowance for credit losses on loans. There were no payment defaults during the three and six months ended June 30, 2023 on loans that had been modified within the previous twelve months.

Old National had not committed to lend any material additional funds to the borrowers whose loans were modified due to financial difficulties at June 30, 2024 or December 31, 2023.

LEASES

Old National has operating and finance leases for land, office space, banking centers, and equipment. These leases are generally for periods of 5 to 20 years with various renewal options. We include certain renewal options in the measurement of our right-of-use assets and lease liabilities if they are reasonably certain to be exercised. Variable lease payments that are dependent on an index or a rate are initially measured using the index or rate at the commencement date and are included in the measurement of the lease liability. Variable lease payments that are not dependent on an index or a rate are excluded from the measurement of the lease liability and are recognized in profit and loss when incurred. Variable lease payments are defined as payments made for the right to use an asset that vary because of changes in facts or circumstances occurring after the commencement date, other than the passage of time.

Old National has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases, non-lease components and other non-components, such as common area maintenance charges, real estate taxes, and insurance are not included in the measurement of the lease liability since they are generally able to be segregated. For certain equipment leases, Old National accounts for the lease and non-lease components as a single lease component using the practical expedient available for that class of assets. Old National does not have any material sub-lease agreements.

The components of lease expense were as follows:

Qualified Affordable Housing Projects and Other Tax Credit Investments

QUALIFIED AFFORDABLE HOUSING PROJECTS AND OTHER TAX CREDIT INVESTMENTS

Old National is a limited partner in several tax-advantaged limited partnerships whose purpose is to invest in approved qualified affordable housing, renewable energy, or other renovation or community revitalization projects. These investments are included in other assets on the balance sheet, with any unfunded commitments included with other liabilities. As of June 30, 2024, Old National expects to recover its remaining investments through the use of the tax credits that are generated by the investments.

The following table summarizes Old National’s investments in qualified affordable housing projects and other tax credit investments:

(1)The amortization expense for the LIHTC and FHTC investments is included in our income tax expense. Prior to the adoption of ASU 2023-02 on January 1, 2024, FHTC amortization expense was included in noninterest expense. NMTC amortization is recognized in noninterest expense in correlation to the recognition of tax credits on our tax return. Amortization expense for the Renewable Energy tax credits is included in noninterest expense.

(2)All of the tax benefits recognized are included in our income tax expense. The tax benefit recognized for the NMTC and Renewable Energy investments primarily reflects the tax credits generated from the investments and excludes the net tax expense (benefit) and deferred tax liability of the investments’ income (loss).

Junior Subordinated Debentures

Junior subordinated debentures related to trust preferred securities are classified in “other borrowings.” Junior subordinated debentures qualify as Tier 2 capital for regulatory purposes, subject to certain limitations.

Through various mergers and acquisitions, Old National assumed junior subordinated debenture obligations related to various trusts that issued trust preferred securities. Old National guarantees the payment of distributions on the trust preferred securities issued by the trusts. Proceeds from the issuance of each of these securities were used to purchase junior subordinated debentures with the same financial terms as the securities issued by the trusts.

Old National, at any time, may redeem the junior subordinated debentures at par and, thereby cause a redemption of the trust preferred securities in whole or in part.

The following table summarizes the terms of our outstanding junior subordinated debentures at June 30, 2024:

Net Deferred Tax Assets

Net deferred tax assets are included in other assets on the balance sheet. At June 30, 2024, net deferred tax assets totaled $456.4 million, compared to $423.3 million at December 31, 2023. No valuation allowance was required on the Company’s deferred tax assets at June 30, 2024 or December 31, 2023.

The Company’s retained earnings at June 30, 2024 included an appropriation for acquired thrifts’ tax bad debt allowances totaling $58.6 million for which no provision for federal or state income taxes has been made. If in the future, this portion of retained earnings were distributed as a result of the liquidation of the Company or its subsidiaries, federal and state income taxes would be imposed at the then applicable rates.

Old National has federal net operating loss carryforwards totaling $75.3 million at June 30, 2024 and $63.6 million at December 31, 2023. This federal net operating loss was acquired from the acquisition of Anchor BanCorp Wisconsin Inc. in 2016, First Midwest Bancorp, Inc. in 2022, and CapStar Financial Holdings, Inc. in 2024. If not used, the federal net operating loss carryforwards will begin expiring in 2032 and later. Old National has recorded state net operating loss carryforwards totaling $111.2 million at June 30, 2024 and $116.9 million at December 31, 2023. If not used, the state net operating loss carryforwards will expire from 2027 to 2036.

The federal and recorded state net operating loss carryforwards are subject to an annual limitation under Internal Revenue Code section 382. Old National believes that all of the federal and recorded state net operating loss carryforwards will be used prior to expiration.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Financial Instruments

DERIVATIVE FINANCIAL INSTRUMENTS

As part of our overall interest rate risk management, Old National uses derivative instruments, including interest rate swaps, collars, caps, and floors. The notional amount does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual agreements. Derivative instruments are recognized on the balance sheet at their fair value and are not reported on a net basis.

Credit risk arises from the possible inability of counterparties to meet the terms of their contracts. Old National’s exposure is limited to the termination value of the contracts rather than the notional, principal, or contract amounts. There are provisions in our agreements with the counterparties that allow for certain unsecured credit exposure up to an agreed threshold. Exposures in excess of the agreed thresholds are collateralized. In addition, we minimize credit risk through credit approvals, limits, and monitoring procedures.

Derivatives Designated as Hedges

Subsequent changes in fair value for a hedging instrument that has been designated and qualifies as part of a hedging relationship are accounted for in the following manner:

Cash flow hedges: changes in fair value are recognized as a component in other comprehensive income (loss).

Fair value hedges: changes in fair value are recognized concurrently in earnings.

As long as a hedging instrument is designated and the results of the effectiveness testing support that the instrument qualifies for hedge accounting treatment, 100% of the periodic changes in fair value of the hedging instrument are accounted for as outlined above. This is the case whether or not economic mismatches exist in the hedging relationship. As a result, there is no periodic measurement or recognition of ineffectiveness. Rather, the full impact of hedge gains and losses is recognized in the period in which the hedged transactions impact earnings.

The change in fair value of the hedging instrument that is included in the assessment of hedge effectiveness is presented in the same income statement line item that is used to present the earnings effect of the hedged item.

Cash Flow Hedges

Interest rate swaps of certain borrowings were designated as cash flow hedges totaling $150.0 million notional amount at both June 30, 2024 and December 31, 2023. Interest rate swaps, collars, and floors related to variable-rate commercial loan pools were designated as cash flow hedges totaling $1.8 billion notional amount at June 30, 2024 and $1.6 billion notional amount at December 31, 2023. The hedges were determined to be effective during all periods presented and we expect them to remain effective during the remaining terms.

Old National has designated its interest rate collars as cash flow hedges. The structure of these instruments is such that Old National pays the counterparty an incremental amount if the collar index exceeds the cap rate. Conversely, Old National receives an incremental amount if the index falls below the floor rate. No payments are required if the collar index falls between the cap and floor rates. 

Old National has designated its interest rate floor transactions as cash flow hedges. The structure of these instruments is such that Old National receives an incremental amount if the index falls below the floor strike rate. No payments are required if the index remains above the floor strike rate.

Fair Value Hedges

Interest rate swaps of certain borrowings were designated as fair value hedges totaling $1.1 billion notional amount at June 30, 2024 and $900.0 million notional amount at December 31, 2023. Interest rate swaps of certain available-for-sale investment securities were designated as fair value hedges totaling $998.1 million notional amount at both June 30, 2024 and December 31, 2023. The hedges were determined to be effective during all periods presented and we expect them to remain effective during the remaining terms.

The following table summarizes Old National’s derivatives designated as hedges:

Amounts reported in AOCI related to cash flow hedges will be reclassified to interest income or interest expense as interest payments are received or paid on Old National’s derivative instruments. During the next 12 months, we

estimate that $6.6 million will be reclassified to interest income and $26.5 million will be reclassified to interest expense.

Derivatives Not Designated as Hedges

Commitments to fund certain mortgage loans (interest rate lock commitments) and forward commitments for the future delivery of mortgage loans to third party investors are considered derivatives. These derivative contracts do not qualify for hedge accounting. At June 30, 2024, the notional amounts of the interest rate lock commitments were $99.1 million and forward commitments were $125.4 million. At December 31, 2023, the notional amounts of the interest rate lock commitments were $25.2 million and forward commitments were $39.5 million. It is our practice to enter into forward commitments for the future delivery of residential mortgage loans to third party investors when interest rate lock commitments are entered into in order to economically hedge the effect of changes in interest rates resulting from our commitment to fund the loans.

Old National also enters into derivative instruments for the benefit of its clients. The notional amounts of these customer derivative instruments and the offsetting counterparty derivative instruments were $6.0 billion at both June 30, 2024 and December 31, 2023. These derivative contracts do not qualify for hedge accounting. These instruments include interest rate swaps, caps, and collars. Commonly, Old National will economically hedge significant exposures related to these derivative contracts entered into for the benefit of clients by entering into offsetting contracts with approved, reputable, independent counterparties with substantially matching terms.

Old National enters into derivative financial instruments as part of its foreign currency risk management strategies. These derivative instruments consist of foreign currency forward contracts to accommodate the business needs of its clients. Old National does not designate these foreign currency forward contracts for hedge accounting treatment.

The following table summarizes Old National’s derivatives not designated as hedges:

Fair Value of Offsetting Derivatives

Certain derivative instruments are subject to master netting agreements with counterparties that provide rights of setoff. The Company records these transactions at their gross fair values and does not offset derivative assets and liabilities in the Consolidated Balance Sheet.

COMMITMENTS, CONTINGENCIES, AND FINANCIAL GUARANTEES

Litigation

At June 30, 2024, there were certain legal proceedings pending against the Company and its subsidiaries in the ordinary course of business. While the outcome of any legal proceeding is inherently uncertain, based on information currently available, the Company’s management does not expect that any potential liabilities arising from pending litigation will have a material adverse effect on the Company’s business, financial position, or results of operations.

Credit-Related Financial Instruments

Old National holds instruments, in the normal course of business with clients, that are considered financial guarantees and are recorded at fair value. Standby letters of credit guarantees are issued in connection with agreements made by clients to counterparties. Standby letters of credit are contingent upon failure of the client to

perform the terms of the underlying contract. Credit risk associated with standby letters of credit is essentially the same as that associated with extending loans to clients and is subject to normal credit policies. The term of these standby letters of credit is typically one year or less. These commitments are not recorded in the consolidated financial statements.

The following table summarizes Old National Bank’s unfunded loan commitments and standby letters of credit:

(dollars in thousands)	June 30, 2024		December 31, 2023
Unfunded loan commitments	$	8,789,910	$	8,912,587
Standby letters of credit (1)	184,482		192,237

(1)Notional amount, which represents the maximum amount of future funding requirements. The carrying value was $1.5 million at June 30, 2024 and $1.3 million at December 31, 2023.

At June 30, 2024, approximately 3% of the unfunded loan commitments had fixed rates, with the remainder having floating rates ranging from 0.00% to 22.49%. The allowance for unfunded loan commitments totaled $25.7 million at June 30, 2024 and $31.2 million at December 31, 2023.

Old National is a party in risk participation transactions of interest rate swaps, which had total notional amounts of $634.9 million at June 30, 2024 and $557.8 million at December 31, 2023.

Fair Value Disclosures [Abstract]

Fair Value

FAIR VALUE

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

•Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

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

•Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

Old National used the following methods and significant assumptions to estimate the fair value of each type of financial instrument:

Investment securities and equity securities: The fair values for investment securities and equity securities are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). Discounted cash flows are calculated using swap and SOFR curves plus spreads that adjust for loss severities, volatility, credit risk, and optionality. During times when trading is more liquid, broker quotes are used (if available) to validate the model. Rating agency and industry research reports as well as defaults and deferrals on individual securities are reviewed and incorporated into the calculations.

Loans held-for-sale: The fair value of loans held-for-sale is determined using quoted prices for a similar asset, adjusted for specific attributes of that loan (Level 2).

Derivative financial instruments: The fair values of derivative financial instruments are based on market quotes developed using observable inputs as of the valuation date (Level 2).

Foreclosed Assets:
Commercial	975		—		—		975
Residential	65		—		—		65

Commercial and commercial real estate loans that are deemed collateral dependent are valued using the discounted cash flows. The liquidation amounts are based on the fair value of the underlying collateral using the most recently available appraisals with certain adjustments made based on the type of property, age of appraisal, current status of the property, and other related factors to estimate the current value of the collateral. These commercial and commercial real estate loans had a principal amount of $163.2 million, with a valuation allowance of $31.4 million at June 30, 2024. Old National recorded provision expense associated with these loans totaling $7.4 million and $17.0 million for the three and six months ended June 30, 2024, respectively, compared to $7.9 million and $19.8 million for the three and six months ended June 30, 2023, respectively.

Other real estate owned and other repossessed property is measured at fair value less costs to sell on a non-recurring basis. Old National did not have any other real estate owned or other repossessed property measured at fair value on a non-recurring basis at June 30, 2024. There were $0.4 million write-downs on other real estate owned for the three and six months ended June 30, 2024, compared to $0.1 million of write-downs for the three and six months ended June 30, 2023.

Assets measured at fair value at December 31, 2023 on a non-recurring basis are summarized below:

(1)Unobservable inputs were weighted by the relative fair value of the instruments.

(2)There was only one foreclosed commercial real estate property and one foreclosed residential real estate property at June 30, 2024 with write-downs during the six months ended June 30, 2024, so no range or weighted average is reported.

Fair Value Option

Old National may elect to report most financial instruments and certain other items at fair value on an instrument-by-instrument basis with changes in fair value reported in net income. After the initial adoption, the election is made at the acquisition of an eligible financial asset, financial liability, or firm commitment or when certain specified reconsideration events occur. The fair value election may not be revoked once an election is made.

Loans Held-For-Sale

Old National has elected the fair value option for loans held-for-sale. For these loans, interest income is recorded in the consolidated statements of income based on the contractual amount of interest income earned on the financial assets (except any that are on nonaccrual status). None of these loans are 90 days or more past due, nor are any on nonaccrual status. Interest income for loans held-for-sale is included in the income statement totaling $0.5 million for three months ended June 30, 2024 and $0.8 million for the six months ended June 30, 2024, compared to $0.3 million and $0.5 million for the three and six months ended June 30, 2023, respectively.

Newly originated conforming fixed-rate and adjustable-rate first mortgage loans are intended for sale and are hedged with derivative instruments. Old National has elected the fair value option to mitigate accounting mismatches in cases where hedge accounting is complex and to achieve operational simplification. The fair value option was not elected for loans held for investment.

The difference between the aggregate fair value and the aggregate remaining principal balance for loans for which the fair value option has been elected was as follows: 

(dollars in thousands)	Aggregate Fair Value		Difference		Contractual Principal
June 30, 2024
Loans held-for-sale	$	66,126	$	525	$	65,601
December 31, 2023
Loans held-for-sale	$	32,006	$	621	$	31,385

Accrued interest at period end is included in the fair value of the instruments.

Accounting Policies [Abstract]

Basis of Presentation

BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements include the accounts of Old National Bancorp and its wholly-owned subsidiaries (hereinafter collectively referred to as “Old National”) and have been prepared in conformity with accounting principles generally accepted in the United States of America and prevailing practices within the banking industry. Such principles require management to make estimates and assumptions that affect the reported amounts of assets, liabilities, and the disclosures of contingent assets and liabilities at the date of the financial statements and amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, the consolidated financial statements contain all the normal and recurring adjustments necessary for a fair statement of the financial position of Old National as of June 30, 2024 and December 31, 2023, and the results of its operations for the three and six months ended June 30, 2024 and 2023. Interim results do not necessarily represent annual results. Certain information and disclosures normally included in notes to consolidated annual financial statements prepared in accordance with GAAP have been condensed or omitted in this Quarterly Report on Form 10-Q pursuant to SEC rules and regulations. These financial statements should be read in conjunction with Old National’s Annual Report on Form 10-K for the year ended December 31, 2023.

All intercompany transactions and balances have been eliminated. Certain prior year amounts have been reclassified to conform to the current presentation. Such reclassifications had no effect on prior period net income or shareholders’ equity and were insignificant amounts.

Recent Accounting Pronouncements

RECENT ACCOUNTING PRONOUNCEMENTS

Accounting Guidance Adopted in 2024

FASB ASC 820 – In June 2022, the FASB issued ASU 2022-03, Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions, to 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. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. The adoption of this guidance on January 1, 2024 did not have a material impact on the consolidated financial statements.

FASB ASC 323 – In March 2023, the FASB issued ASU 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method, which allows 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 ASU is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. The adoption of this guidance on a modified retrospective basis on January 1, 2024 did not have a material impact on the consolidated financial statements.

FASB ASC 848 – In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides temporary, optional guidance to ease the potential burden in accounting for, or recognizing the effects of, the transition away from LIBOR or other interbank offered rate on financial reporting. The guidance is applicable only to contracts or hedge accounting relationships that reference LIBOR or another reference rate expected to be discontinued.

In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which defers the sunset date of relief provisions within Topic 848 from December 31, 2022 to December 31, 2024. The objective of the guidance in Topic 848 is to provide relief during the transition period.

The amendments in this ASU are effective March 12, 2020 through December 31, 2024. As of June 30, 2024, substantially all of the Company’s LIBOR exposure was addressed and remaining LIBOR-based contracts are expected to transition to alternate reference rates at their next index reset dates. Old National believes the adoption of this guidance on activities subsequent to June 30, 2024 will not have a material impact on the consolidated financial statements.

Accounting Guidance Pending Adoption 

FASB ASC 280 – In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments are intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. In addition, the amendments enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment, and contain other disclosure requirements. The purpose of the amendments is to enable investors to better understand an entity’s overall performance and assess potential future cash flows. A public entity should apply the amendments retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. This 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. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

FASB ASC 740 – In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. Among other things, these amendments require that public business entities on an annual basis disclose additional information in specified categories with respect to the reconciliation of the effective tax rate to the statutory rate for federal, state, and foreign income taxes. It also requires greater detail about individual reconciling items in the rate reconciliation to the extent the impact of those items exceeds a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income (loss) by the applicable statutory income tax rate). In addition, the ASU requires information pertaining to taxes paid (net of refunds received) to be disaggregated for federal, state, and foreign taxes and further disaggregated for specific jurisdictions to the extent the related amounts are equal to or greater than 5 percent of total income taxes paid (net of refunds received). The amendments in this ASU are effective for annual periods beginning after December 15, 2024. Early adoption is permitted. Old National is currently evaluating the impact of adopting the new guidance on the consolidated financial statements.
