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, 2026, these loans totaled $3.7 billion, of which $1.8 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. Thefour 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, business banking credit center (“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 $58.8 million at June 30, 2026 and $75.1 million at December 31, 2025.

(2) Includes unamortized premiums and discounts, and unamortized deferred fees and costs of $455.6 million at June 30, 2026 and $540.1 million at December 31, 2025.

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 classified 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 254%, 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, 2026.

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 Fair Isaac Corporation (“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, home price index, 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 macroeconomic forecasts of unemployment, gross domestic product, home price index, and the BBB ratio may prove to be more severe and/or prolonged than our baseline forecast due to a variety of considerations. 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, 2026 and June 30, 2025 included the impact of acquisition accounting adjustments and provision related to the Bremer acquisition which was completed on May 1, 2025. In addition, the provision for credit losses on loans in the three and six months ended June 30, 2025 included $69.1 million to establish an allowance for credit losses on non-PCD Bremer loans acquired. Accrued interest receivable on loans is excluded from the estimate of credit losses and totaled $223.7 million at June 30, 2026, compared to $228.6 million at December 31, 2025.

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:

Credit Quality

Old National’s management monitors the credit quality of its loans on an ongoing basis with the asset quality rating (“AQR”) for commercial, commercial real estate, and BBCC 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 Old National’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 Old National 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.

For residential real estate and consumer loan classes, Old National evaluates credit quality based on the aging status of the loan and by payment activity. The performing or nonperforming status is updated on an on-going basis dependent upon improvement and deterioration in credit quality. The following table presents the amortized cost of term residential real estate and consumer loans based on payment activity and origination year:

The following table summarizes the gross charge-offs of loans by loan portfolio segment and origination year:

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:

The following table presents the amortized cost basis of loans on nonaccrual status and loans past due 90 days or more and still accruing by class of loan:

Interest income recognized on nonaccrual loans was insignificant during the three and six months ended June 30, 2026 and 2025.

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 period-over-period 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 forgiven 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 by class of loans and type of modification:

Old National monitors the performance of financial difficulty modifications to understand the effectiveness of its efforts. The following table presents the performance of financial difficulty modifications in the twelve months following modification:

The following table summarizes the nature of the financial difficulty modifications by class of loans:

There were payment defaults on $12.1 million and $18.5 million of loans during the three and six months ended June 30, 2026, respectively, to borrowers whose loans were modified due to financial difficulties within the previous twelve months. There were payment defaults on $4.6 million and $9.1 million of loans during the three and six months ended June 30, 2025, respectively, to borrowers whose loans had been modified within the previous twelve months. The payment defaults did not materially impact the allowance for credit losses on loans.

Old National hadnot committed to lend any material additional funds to the borrowers whose loans were modified due to financial difficulties at June 30, 2026 or December 31, 2025.

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 at acquisition was as follows:

(1)Old National acquired Bremer effective May 1, 2025.
