UMB FINANCIAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

FOR THE THREE MONTHS ENDED MARCH 31, 2024 (UNAUDITED)

1. Financial Statement Presentation

The Consolidated Financial Statements include the accounts of UMB Financial Corporation and its subsidiaries (collectively, the Company) after the elimination of all intercompany transactions. In the opinion of management of the Company, all adjustments relating to items that are of a normal recurring nature and necessary for a fair presentation of the financial position and results of operations have been made. The results of operations and cash flows for the interim periods presented may not be indicative of the results of the full year ending December 31, 2024. The financial statements should be read in conjunction with “Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations” within this Quarterly Report on Form 10-Q (the Form 10-Q) and in conjunction with the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the Securities and Exchange Commission (SEC) on February 22, 2024 (the Form 10-K).

The Company is a financial holding company, which offers a wide range of banking and other financial services to its customers through its branches and offices. The Company’s national bank, UMB Bank, National Association (the Bank), has its principal office in Missouri and also has branches in Arizona, Colorado, Illinois, Kansas, Nebraska, Oklahoma, and Texas. The Company also has offices in Pennsylvania, South Dakota, Indiana, Utah, Minnesota, California, Wisconsin, Iowa, Delaware, and New York.

2. Summary of Significant Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. These estimates and assumptions also impact reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A summary of the significant accounting policies to assist the reader in understanding the financial presentation is provided in the Notes to Consolidated Financial Statements in the Form 10-K.

Cash and cash equivalents

Cash and cash equivalents include Cash and due from banks and amounts due from the Federal Reserve Bank (FRB). Cash on hand, cash items in the process of collection, and amounts due from correspondent banks are included in Cash and due from banks. Amounts due from the FRB are interest-bearing for all periods presented and are included in the Interest-bearing due from banks line on the Company’s Consolidated Balance Sheets.

This table provides a summary of cash and cash equivalents as presented on the Consolidated Statements of Cash Flows as of March 31, 2024 and March 31, 2023 (in thousands):

	March 31,
	2024		2023
Due from the FRB	$	6,586,145	$	3,051,056
Cash and due from banks		356,963		472,248
Cash and cash equivalents at end of period	$	6,943,108	$	3,523,304

Also included in the Interest-bearing due from banks, but not considered cash and cash equivalents, are interest-bearing accounts held at other financial institutions, which totaled $87.0 million and $70.1 million at March 31, 2024 and March 31, 2023, respectively.

9

Per Share Data

Basic net income per share is computed based on the weighted average number of shares of common stock outstanding during each period. Diluted quarter-to-date net income per share includes the dilutive effect of 257,348 and 311,546 shares issuable upon the exercise of stock options and nonvested restricted stock units granted by the Company that were outstanding at March 31, 2024 and 2023, respectively.

Certain options and restricted stock units issued under employee benefit plans were excluded from the computation of diluted earnings per share because they were anti-dilutive. For the three months ended March 31, 2024, there were no outstanding stock options and restricted stock units excluded from the computation of diluted income per share. For the three months ended March 31, 2023, there were 166,578 outstanding stock options or restricted stock units excluded from the computation of diluted income per share because their inclusion would have been anti-dilutive.

Derivatives

The Company records all derivatives on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Currently, ten of the Company’s derivatives are designated in qualifying hedging relationships. The remainder of the Company’s derivatives are not designated in qualifying hedging relationships, as the derivatives are not used to manage risks within the Company’s assets or liabilities. All changes in fair value of the Company’s non-designated derivatives and fair value hedges are recognized directly in earnings. Changes in fair value of the Company’s cash flow hedges are recognized in accumulated other comprehensive income (AOCI) and are reclassified to earnings when the hedged transaction affects earnings.

3. New Accounting Pronouncements

Troubled Debt Restructurings In March 2022, the FASB issued Accounting Standards Update (ASU) No. 2022-02, “Financial Instruments – Credit Losses: Troubled Debt Restructurings and Vintage Disclosures.” The ASU eliminated the accounting guidance for troubled debt restructurings (TDR) by creditors and enhances disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. The amendments also added requirements to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases, disclosed by credit-quality indicator and class of financing receivable. The amendments in this update were adopted prospectively on January 1, 2023. The adoption of the amendments had no impact on the Consolidated Financial Statements aside from additional and revised financial statement disclosures. See Note 3, "Loans and Allowance for Credit Losses" for related disclosures.

Equity-Method Investments In March 2023, the FASB issued ASU No. 2023-02, "Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method." The ASU allows 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. Previously, this method was only available for qualifying tax equity investments in low-income housing tax credit structures. The Company adopted the amended guidance on January 1, 2024, upon which the Company elected to continue the use of the practical expedient under ASC 323-740-35-4 to account for low-income housing tax credit and historic tax credit investments. Under the practical expedient, the cost of a tax equity investment is amortized in proportion to income tax credits only and is recorded on a net basis within income tax expense. The adoption of this amendment did not have any impact on the Consolidated Financial Statements aside from annual disclosures which will be included in the Company's Annual Report on Form 10-K.

Income Taxes In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update require additional disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this update are effective for fiscal years

10

beginning after December 15, 2024. Early adoption is permitted. The adoption of this accounting pronouncement will have no impact on the Consolidated Financial Statements aside from additional disclosures.

4. Loans and Allowance for Credit Losses

Loan Origination/Risk Management

The Company has certain lending policies and procedures in place that are designed to minimize the level of risk within the loan portfolio. Diversification of the loan portfolio manages the risk associated with fluctuations in economic conditions. Authority levels are established for the extension of credit to ensure consistency throughout the Company. It is necessary that policies, processes, and practices implemented to control the risks of individual credit transactions and portfolio segments are sound and adhered to. The Company maintains an independent loan review department that reviews and validates the risk assessment on a continual basis. Management regularly evaluates the results of the loan reviews. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Company’s policies and procedures.

Commercial and industrial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. Commercial loans are made based on the identified cash flows of the borrower and on the underlying collateral provided by the borrower. The cash flows of the borrower, 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. 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 from its customers.

Specialty lending loans include Asset-based loans, which are offered primarily in the form of revolving lines of credit to commercial borrowers that do not generally qualify for traditional bank financing. Asset-based loans are underwritten based primarily upon the value of the collateral pledged to secure the loan, rather than on the borrower’s general financial condition. The Company utilizes pre-loan due diligence techniques, monitoring disciplines, and loan management practices common within the asset-based lending industry to underwrite loans to these borrowers.

Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans, in addition to those of real estate loans. These 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 largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. The Company requires that an appraisal of the collateral be made at origination and on an as-needed basis, in conformity with current market conditions and regulatory requirements. The underwriting standards address both owner and non-owner-occupied real estate. Also included in Commercial real estate are Construction loans that are underwritten using feasibility studies, independent appraisal reviews, sensitivity analysis or absorption and lease rates, and financial analysis of the developers and property owners. Construction loans are based upon estimates of costs and value associated with the complete project. 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, sales of developed property or an interim loan commitment from the Company 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 repayment being sensitive to interest rate changes, governmental regulation of real property, economic conditions, completion of the construction project, and the availability of long-term financing.

Consumer real estate loans, including residential real estate and home equity loans, are underwritten based on the borrower’s loan-to-value percentage, collection remedies, and overall credit history.

Consumer loans are underwritten based on the borrower’s repayment ability. The Company monitors delinquencies on all of its consumer loans and leases. The underwriting and review practices combined with the

11

relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Consumer loans and leases that are 90 days past due or more are considered non-performing.

Credit cards include both commercial and consumer credit cards. Commercial credit cards are generally unsecured and are underwritten with criteria similar to commercial loans, including an analysis of the borrower’s cash flow, available business capital, and overall creditworthiness of the borrower. Consumer credit cards are underwritten based on the borrower’s repayment ability. The Company monitors delinquencies on all of its consumer credit cards and periodically reviews the distribution of credit scores relative to historical periods to monitor credit risk on its consumer credit card loans. During the first quarter of 2024, the Company purchased a co-branded credit card portfolio. The purchase included $109.4 million in credit card receivables.

Credit risk is a potential loss resulting from nonpayment of either the primary or secondary exposure. Credit risk is mitigated with formal risk management practices and a thorough initial credit-granting process including consistent underwriting standards and approval process. Control factors or techniques to minimize credit risk include knowing the client, understanding total exposure, analyzing the client and debtor’s financial capacity, and monitoring the client’s activities. Credit risk and portions of the portfolio risk are managed through concentration considerations, average risk ratings, and other aggregate characteristics.

Credit Quality Indicators

As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to the risk grading of specified classes of loans, net charge-offs, non-performing loans, and general economic conditions.

16

The Company utilizes a risk grading matrix to assign a rating to each of its commercial, commercial real estate, and construction real estate loans. Changes in credit risk are monitored on a continuous basis and changes in risk ratings are made when identified. The loan ratings are summarized into the following categories: Non-watch list, Watch, Special Mention, Substandard, and Doubtful. Any loan not classified in one of the categories described below is considered to be a Non-watch list loan. A description of the general characteristics of the loan rating categories is as follows:

•Watch – This rating represents credit exposure that presents higher than average risk and warrants greater than routine attention by Company personnel due to conditions affecting the borrower, the borrower’s industry, or the economic environment. These conditions have resulted in some degree of uncertainty that results in higher-than-average credit risk. These loans are considered pass-rated credits.

•Special Mention – This rating reflects 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 asset or the borrower’s credit position at some future date. The rating is not adversely classified and does not expose an institution to sufficient risk to warrant adverse classification.

•Substandard – This rating represents an asset inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans in this category are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified as substandard.

•Doubtful – This rating represents an asset that has all the weaknesses inherent in an asset classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work to the advantage of strengthening the asset, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, liquidation procedures, capital injection, or perfecting liens.

Commercial and industrial

A discussion of the credit quality indicators that impact each type of collateral securing Commercial and industrial loans is included below:

Equipment, accounts receivable, and inventory General commercial and industrial loans are secured by working capital assets and non-real estate assets. The general purpose of these loans is for financing capital expenditures and current operations for commercial and industrial entities. These assets are short-term in nature. In the case of accounts receivable and inventories, the repayment of debt is reliant upon converting assets into cash or through goods and services being sold and collected. Collateral-based risk is due to aged short-term assets, which can be indicative of underlying issues with the borrower and lead to the value of the collateral being overstated.

Agriculture Agricultural loans are secured by non-real estate agricultural assets. These include shorter-term assets such as equipment, crops, and livestock. The risks associated with loans to finance crops or livestock include the borrower’s ability to successfully raise and market the commodity. Adverse weather conditions and other natural perils can dramatically affect farmers’ or ranchers’ production and ability to service debt. Volatile commodity prices present another significant risk for agriculture borrowers. Market price volatility and production cost volatility can affect both revenues and expenses.

Overdrafts Commercial overdrafts are typically short-term and unsecured. Some commercial borrowers tie their overdraft obligation to their line of credit, so any draw on the line of credit will satisfy the overdraft.

Based on the factors noted above for each type of collateral, the Company assigns risk ratings to borrowers based on their most recently assessed financial position.

Specialty lending

A discussion of the credit quality indicators that impact each type of collateral securing Specialty loans is included below:

Asset-based lending General asset-based loans are secured by accounts receivable, inventory, equipment, and real estate. The purpose of these loans is for financing current operations for commercial customers. The repayment of debt is reliant upon collection of the accounts receivable within 30 to 90 days or converting assets into cash or through goods and services being sold and collected. The Company tracks each individual borrower credit risk based on their loan to collateral position. Any borrower position where the underlying value of collateral is below the fair value of the loan is considered out-of-margin and inherently higher risk.

The following table provides a summary of the amortized cost balance by risk rating for asset-based loans as of March 31, 2024 and December 31, 2023 (in thousands):

	Asset-based lending
Risk	March 31, 2024		December 31, 2023
In-margin	$	508,162	$	498,786
Out-of-margin		—		—
Total	$	508,162	$	498,786

Commercial real estate

A discussion of the credit quality indicators that impact each type of collateral securing Commercial real estate loans is included below:

Owner-occupied Owner-occupied loans are secured by commercial real estate. These loans are often longer tenured and susceptible to multiple economic cycles. The loans rely on the owner-occupied operations to service debt which cover a broad spectrum of industries. Real estate debt can carry a significant amount of leverage for a borrower to maintain.

Non-owner-occupied Non-owner-occupied loans are secured by commercial real estate. These loans are often longer tenured and susceptible to multiple economic cycles. The key element of risk in this type of lending is the cyclical nature of real estate markets. Although national conditions affect the overall real estate industry, the effect of national conditions on local markets is equally important. Factors such as unemployment rates, consumer demand, household formation, and the level of economic activity can vary widely from state to state and among metropolitan areas. In addition to geographic considerations, markets can be defined by property type. While all sectors are influenced by economic conditions, some sectors are more sensitive to certain economic factors than others.

Farmland Farmland loans are secured by real estate used for agricultural purposes such as crop and livestock production. Assets used as collateral are long-term assets that carry the ability to have longer amortizations and maturities. Longer terms carry the risk of added susceptibility to market conditions. The limited purpose of some Agriculture-related collateral affects credit risk because such collateral may have limited or no other uses to support values when loan repayment problems emerge.

5+ Multi-family 5+ multi-family loans are secured by a multi-family residential property. The primary risks associated with this type of collateral are largely driven by economic conditions. The national and local market conditions can change with unemployment rates or competing supply of multi-family housing. Tenants may not be able to afford their housing or have better options and this can result in increased vacancy. Rents may need to be lowered to fill apartment units. Increased vacancy and lower rental rates not only drive the borrower’s ability to repay debt but also contribute to how the collateral is valued.

1-4 Family construction 1-4 family construction loans are secured by 1-4 family residential real estate and are in the process of construction or improvements being made. The predominant risk inherent to this portfolio is the risk associated with a borrower’s ability to successfully complete a project on time and within budget. Market conditions also play an important role in understanding the risk profile. Risk from adverse changes in market conditions from the start of development to completion can result in deflated collateral values.

19

General construction General construction loans are secured by commercial real estate in process of construction or improvements being made and their repayment is dependent on the collateral’s completion. Construction lending presents unique risks not encountered in term financing of existing real estate. The predominant risk inherent to this portfolio is the risk associated with a borrower’s ability to successfully complete a project on time and within budget. Commercial properties under construction are susceptible to market and economic conditions. Demand from prospective customers may erode after construction begins because of a general economic slowdown or an increase in the supply of competing properties.

Based on the factors noted above for each type of collateral, the Company assigns risk ratings to borrowers based on their most recently assessed financial position.

The following tables provide a summary of the amortized cost balance by collateral type and risk rating as of March 31, 2024 and December 31, 2023 (in thousands):

Consumer real estate

A discussion of the credit quality indicators that impact each type of collateral securing Consumer real estate loans is included below:

22

HELOC HELOC loans are revolving lines of credit secured by 1-4 family residential property. The primary risk is the borrower’s inability to repay debt. Revolving notes are often associated with HELOCs that can be secured by real estate without a 1st lien priority. Collateral is susceptible to market volatility impacting home values or economic downturns.

First lien: 1-4 family First lien 1-4 family loans are secured by a first lien on 1-4 family residential property. These term loans carry longer maturities and amortizations. The longer tenure exposes the borrower to multiple economic cycles, coupled with longer amortizations that result in smaller principal reduction early in the life of the loan. Collateral is susceptible to market volatility impacting home values.

Junior lien: 1-4 family Junior lien 1-4 family loans are secured by a junior lien on 1-4 family residential property. The Company’s primary risk is the borrower’s inability to repay debt and not being in a first lien position. Collateral is susceptible to market volatility impacting home values or economic downturns.

A borrower is considered non-performing if the Company has ceased the recognition of interest and the loan is placed on non-accrual. Charge-offs and borrower performance are tracked on a loan origination vintage basis. Certain vintages, based on their maturation cycle, could be at higher risk due to collateral-based risk factors.

Consumer

A discussion of the credit quality indicators that impact each type of collateral securing Consumer loans is included below:

Revolving line Consumer Revolving lines of credit are secured by consumer assets other than real estate. The primary risk associated with this collateral is related to market volatility and the value of the underlying financial assets.

Auto Direct consumer auto loans are secured by new and used consumer vehicles. The primary risk with this collateral class is the rate at which the collateral depreciates.

Other This category includes Other consumer loans made to an individual. The primary risk for this category is for those loans where the loan is unsecured. This collateral type also includes other unsecured lending such as consumer overdrafts.

24

A borrower is considered non-performing if the Company has ceased the recognition of interest and the loan is placed on non-accrual. Charge-offs and borrower performance are tracked on a loan origination vintage basis. Certain vintages, based on their maturation cycle, could be at higher risk due to collateral-based risk factors.

Credit cards

A discussion of the credit quality indicators that impact Credit card loans is included below:

Consumer Consumer credit card loans are revolving loans made to individuals. The primary risk associated with this collateral class is credit card debt which is generally unsecured; therefore, repayment depends primarily on a borrower’s willingness and capacity to repay. The highly competitive environment for credit card lending provides consumers with ample opportunity to hold several credit cards from different issuers and to pay only minimum monthly payments on outstanding balances. In such an environment, borrowers may become over-extended and unable to repay, particularly in times of an economic downturn or a personal catastrophic event.

The consumer credit card portfolio is segmented by borrower payment activity. Transactors are defined as accounts that pay off their balance by the end of each statement cycle. Revolvers are defined as an account that carries a balance from one statement cycle to the next. These accounts incur monthly finance charges, and, sometimes, late fees. Revolvers are inherently higher risk and are tracked by credit score.

Commercial Commercial credit card loans are revolving loans made to small and commercial businesses. The primary risk associated with this collateral class is credit card debt which is generally unsecured; therefore, repayment depends primarily on a borrower’s willingness and capacity to repay. Borrowers may become over-extended and unable to repay, particularly in times of an economic downturn or a catastrophic event.

The commercial credit card portfolio is segmented by current and past due payment status. A borrower is past due after 30 days. In general, commercial credit card customers do not have incentive to hold a balance resulting in paying interest on credit card debt as commercial customers will typically have other debt obligations with lower interest rates in which they can utilize for capital.

The following table provides a summary of the amortized cost balance of consumer credit cards by risk rating as of March 31, 2024 and December 31, 2023 (in thousands):

Leases and other

A discussion of the credit quality indicators that impact each type of collateral securing Leases and other loans is included below:

Leases Leases are either loans to individuals for household, family and other personal expenditures or are loans related to all other direct financing and leveraged leases on property for leasing to lessees other than for household, family and other personal expenditure purposes. All leases are secured by the lease between the lessor and the lessee. These assignments grant the creditor a security interest in the rent stream from any lease, an important source of cash to pay the note in case of the borrower’s default.

Other Other loans are loans that are obligations of states and political subdivisions in the U.S., loans to non-depository financial institutions, loans for purchasing or carrying securities, or all other non-consumer loans. Risk associated with other loans is tied to the underlying collateral by each type of loan. Collateral is generally equipment, accounts receivable, inventory, 1-4 family residential construction and susceptible to the same risks mentioned with those collateral types previously. Other risks consist of collateral that is secured by the stock of a non-depository financial institution, which can be unlisted stock with a limited market for the stock, or volatility of asset values driven by market performance.

Based on the factors noted above for each type of collateral, the Company assigns risk ratings to borrowers based on their most recently assessed financial position.

The following table provides a summary of the amortized cost balance by collateral type and risk rating as of March 31, 2024 and December 31, 2023 (in thousands):

Allowance for Credit Losses

The allowance for credit losses (ACL) is a valuation account that is deducted from loans’ and held-to-maturity (HTM) securities’ amortized cost bases to present the net amount expected to be collected on the instrument. Loans and HTM securities are charged off against the ACL when management believes the balance has become uncollectible. Expected recoveries are included in the allowance and do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.

Management estimates the allowance balance using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and supportable economic forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses and is tracked over an economic cycle to capture a ‘through the cycle’ loss history. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in portfolio industry-based segmentation, risk rating and credit score changes, average prepayment rates, changes in environmental conditions, or other relevant factors. For economic forecasts, the Company uses the Moody’s baseline scenario. The Company has developed a dynamic reasonable and supportable forecast period that ranges from one to three years and changes based on economic conditions. Due to current economic conditions, the Company’s reasonable and supportable forecast period is one year. After the reasonable and supportable forecast period, the Company reverts to historical losses. The reversion method applied to each portfolio can either be cliff or straight-line over four quarters.

The ACL is measured on a collective (pool) basis when similar risk characteristics exists. The ACL also incorporates qualitative factors which represent adjustments to historical credit loss experience for items such as concentrations of credit and results of internal loan review. The Company has identified the following portfolio

27

segments and measures the allowance for credit losses using the following methods. The Company’s portfolio segmentation consists of Commercial and industrial, Specialty lending, Commercial real estate, Consumer real estate, Consumer, Credit cards, Leases and other, and Held-to-maturity securities. Multiple modeling techniques are used to measure credit losses based on the portfolio.

The ACL for Commercial and industrial and Leases and other segments are measured using a probability of default and loss given default method. Primary risk drivers within the segment are risk ratings of the individual loans along with changes of macro-economic variables. The economic variables utilized are typically comprised of leading and lagging indicators. The ACL for Commercial and industrial loans is calculated by modeling probability of default (PD) over future periods multiplied by historical loss given default rates (LGD) multiplied by contractual exposure at default minus any estimated prepayments and charge offs.

Collateral positions for Specialty lending loans are continuously monitored by the Company and the borrower is required to continually adjust the amount of collateral securing the loan. Credit losses are measured for any position where the amortized cost basis is greater than the fair value of the collateral. The ACL for specialty lending loans is calculated by using a bottom-up approach comparing collateral values to outstanding balances.

The ACL for the Commercial real estate segment is measured using a PD and LGD method. Primary risk characteristics within the segment are risk ratings of the individual loans, along with changes of macro-economic variables, such as interest rates, CRE price index, median household income, construction activity, farm income, and vacancy rates. The ACL for Commercial real estate loans is calculated by modeling PD over future periods based on peer bank data. The PD loss rate is then multiplied by historical LGD multiplied by contractual exposure at default minus any estimated prepayments and charge offs.

The ACL for the Consumer real estate and Consumer segments are measured using an origination vintage loss rate method applied to the loans’ amortized cost balance. The primary risk driver within the segments is year of origination along with changes of macro-economic variables such as unemployment and the home price index.

The Credit card segment contains both consumer and commercial credit cards. The ACL for Consumer credit cards is measured using a PD and LGD method for Revolvers and average historical loss rates across a defined lookback period for Transactors. The PD and LGD method used for Revolvers is similar in nature to the method used in the Commercial and industrial and Commercial real estate segments. Primary risk drivers within the segment are credit ratings of the individual card holders along with changes of macro-economic variables such as unemployment and retail sales. The ACL for Commercial credit cards is measured using roll-rate loss rate method based on days past due.

The ACL for the State and political HTM securities segment is measured using a loss rate method based on historical bond rating transitions. Primary risk drivers within the segment are bond ratings in the portfolio along with changes of macro-economic conditions. There is no ACL for the U.S. Agency and GSE mortgage-backed HTM securities portfolios as they are considered to be agency-backed securities with no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. For further discussion on these securities, including the aging and amortized cost balance of HTM securities, see Note 5, “Securities.”

See the credit quality indicators presented previously for a summary of current risk in the Company’s portfolio. Changes in economic forecasts will affect all portfolio segments, updated financial records from borrowers will affect portfolio segments by risk rating, updated credit scores will affect consumer credit cards, payment performance will affect consumer and commercial credit card portfolio segments, and updated bond credit ratings will affect held-to-maturity securities. The Company actively monitors all credit quality indicators for risk changes that will influence the current estimate.

Expected credit losses are estimated over the contractual term of the loans, adjusted for prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a concessionary loan term has been granted to a borrower experiencing financial difficulty or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by the Company.

28

Credit card receivables do not have stated maturities. In determining the estimated life of a credit card receivable, management first estimates the future cash flows expected to be received and then applies those expected future cash flows to the credit card balance. Expected credit losses for credit cards are determined by estimating the amount and timing of principal payments expected to be received as payment for the balance outstanding as of the reporting period until the expected payments have been fully allocated. The ACL is recorded for the excess of the balance outstanding as of the reporting period over the expected principal payments.

Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually include loans on nonaccrual, loans that include modifications deemed concessionary made to borrowers experiencing financial difficulty, or any loans specifically identified, and are excluded from the collective evaluation. When it is determined that payment of interest or recovery of all principal is questionable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for undiscounted selling costs as appropriate. All loans are classified as collateral dependent if placed on non-accrual or include modifications made to borrowers experiencing financial difficulty.

Modifications made to Borrowers Experiencing Financial Difficulty

In the normal course of business, the Company may execute loan modifications with borrowers. These modifications are analyzed to determine whether the modification is considered concessionary, long term and made to a borrower experiencing financial difficulty. The Company’s modifications generally include interest rate adjustments, principal reductions, and amortization and maturity date extensions. These modifications allow the borrower short-term cash relief to allow them to improve their financial condition. If a loan modification is determined to be made to a borrower experiencing financial difficulty, the loan is considered collateral dependent and evaluated as part of the ACL as described above in the Allowance for Credit Losses section of this note.

For the three months ended March 31, 2024 and March 31, 2023, the Company did not modify any loans made to borrowers experiencing financial difficulty.

31

The Company had no commitments to lend to borrowers experiencing financial difficulty for which the Company has modified an existing loan as of March 31, 2024 and 2023. The Company monitors loan payments on an on-going basis to determine if a loan is considered to have a payment default. Determination of payment default involves analyzing the economic conditions that exist for each customer and their ability to generate positive cash flows during the loan term. For the three-month period ended March 31, 2024 and March 31, 2023, the Company had no loan modifications made to borrowers experiencing financial difficulty for which there was a payment default within the 12 months following the modification date.

The unrealized losses in the Company’s investments were caused by changes in interest rates, and not from a decline in credit of the underlying issuers. The U.S. Treasury, U.S. Agency, and GSE mortgage-backed securities are all considered to be agency-backed securities with no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. The changes in fair value in the agency-backed portfolios are solely driven by change in interest rates caused by changing economic conditions. The Company has no knowledge of any underlying credit issues and the cash flows underlying the debt securities have not changed and are not expected to be impacted by changes in interest rates.

33

For the State and political subdivision portfolio, the majority of the Company’s holdings are in general obligation bonds, which have a very low historical default rate due to issuers generally having unlimited taxing authority to service the debt. For the State and political, Corporates, and Collateralized loan obligations portfolios, the Company has a robust process for monitoring credit risk, including both pre-purchase and ongoing post-purchase credit reviews and analysis. The Company monitors credit ratings of all bond issuers in these segments and reviews available financial data, including market and sector trends.

During the three months ended March 31, 2023, the Company recorded a $4.8 million impairment on one Corporate available-for-sale security.

As of March 31, 2024 and December 31, 2023, there was no ACL related to the Company’s available-for-sale securities as the decline in fair value did not result from credit issues.

During the year ended December 31, 2022, securities with an amortized cost of $4.1 billion and a fair value of $3.8 billion were transferred from the available-for-sale classification to the held-to-maturity classification as the Company has the positive intent and ability to hold these securities to maturity. The transfers of securities were made at fair value at the time of transfer. The unrealized holding gain or loss at the time of transfer is retained in AOCI and will be amortized over the remaining life of the securities, offsetting the related amortization of discount or premium on the transferred securities. No gains or losses were recognized at the time of the transfers. The amortized cost balance of securities held to maturity in the tables above includes a net unamortized unrealized loss of $198.4 million at March 31, 2024.

Accrued interest on securities held to maturity totaled $24.0 million and $27.2 million as March 31, 2024 and December 31, 2023, respectively, and is included in the Accrued income line on the Company’s Consolidated Balance Sheets. The total amount of accrued interest is excluded from the amortized cost of held-to-maturity securities presented above. Further, the Company has elected not to measure an ACL for accrued interest receivable.

The unrealized losses in the Company’s held-to-maturity portfolio were caused by changes in the interest rate environment. The U.S. Agency and GSE mortgage-backed securities are considered to be agency-backed securities with no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. Therefore, the Company’s expected lifetime loss for these portfolios is zero and there is no ACL recorded for these portfolios. The Company has no knowledge of any underlying credit issues and the cash flows underlying the debt securities have not changed and are not expected to be impacted by changes in interest rates.

For the State and political subdivision portfolio, the Company’s holdings are in general obligation bonds as well as private placement bonds, which have very low historical default rates due to issuers generally having unlimited taxing authority to service the debt. The Company has a robust process for monitoring credit risk, including both pre-purchase and ongoing post-purchase credit reviews and analysis. The Company monitors credit ratings of all bond issuers in these segments and reviews available financial data, including market and sector trends. The underlying bonds are evaluated for credit losses in conjunction with management’s estimate of the ACL based on credit rating.

The Company’s remaining borrowing capacity with the BTFP was $30.0 million and its remaining borrowing capacity at the Federal Reserve Discount Window was $11.0 billion as of March 31, 2024.

The Company has a revolving line of credit with Wells Fargo Bank, N.A. which allows the Company to borrow up to $30.0 million for general working capital purposes. The interest rate applied to borrowed balances will be at the Company’s option either 1.40% above Term SOFR or 1.75% below the prime rate on the date of an advance. The Company pays a 0.4% unused commitment fee for unused portions of the line of credit. The Company currently has no outstanding balance on this line of credit.

The Company utilizes repurchase agreements to facilitate the needs of customers and to facilitate secured short-term funding needs. Repurchase agreements are stated at the amount of cash received in connection with the transaction. The Company monitors collateral levels on a continuous basis and may be required to provide additional collateral based on the fair value of the underlying securities. Securities pledged as collateral under repurchase agreements are maintained with the Company’s safekeeping agents.

9. Revenue Recognition

The following is a description of the principal activities from which the Company generates revenue that are within the scope of ASC 606, Revenue from Contracts with Customers:

Trust and securities processing – Trust and securities processing income consists of fees earned on personal and corporate trust accounts, custody of securities services, trust investments and wealth management services, and mutual fund and alternative asset servicing. The performance obligations related to this revenue include items such as performing full bond trustee service administration, investment advisory services, custody and record-keeping services, and fund administrative and accounting services. These fees are part of long-term contractual agreements and the performance obligations are satisfied upon completion of service and fees are generally a fixed flat monthly rate or based on a percentage of the account’s market value per the contract with the customer. These fees are primarily recorded within the Company’s Institutional and Personal Banking segments.

Trading and investment banking – Trading and investment banking income consists of income earned related to the Company’s trading securities portfolio, including futures hedging, dividends, bond underwriting, and other securities incomes. The vast majority of this revenue is recognized in accordance with ASC 320, Debt and Equity Securities, and is out of the scope of ASC 606. A portion of trading and investment banking represents fees earned for management fees, commissions, and underwriting of corporate bond issuances. The performance obligations related to these fees include reviewing the credit worthiness of the customer, ensuring appropriate regulatory approval and participating in due diligence. The fees are fixed per the bond prospectus and the performance obligations are satisfied upon registration approval of the bonds by the applicable regulatory agencies. Revenue is recognized at the point in time upon completion of service and when approval is granted by the regulators.

41

Service charges on deposits – Service charges on deposit accounts represent monthly analysis fees recognized for the services related to customer deposit accounts, including account maintenance and depository transactions processing fees. Commercial Banking and Institutional Banking depository accounts charge fees in accordance with the customer’s pricing schedule while Personal Banking account holders are generally charged a flat service fee per month. Deposit service charges for the healthcare accounts included in the Institutional Banking segment are priced according to either standard pricing schedules with individual account holders or according to service agreements between the Company and employer groups or third-party administrators. The Company satisfies the performance obligation related to providing depository accounts monthly as transactions are processed and deposit service charge revenue is recorded monthly. These fees are recognized within all Business Segments.

Insurance fees and commissions – Insurance fees and commissions includes all insurance-related fees earned, including commissions for individual life, variable life, group life, health, group health, fixed annuity, and variable annuity insurance contracts. The performance obligations related to these revenues primarily represent the placement of insurance policies with the insurance company partners. The fees are based on the contracts with insurance company partners and the performance obligations are satisfied when the terms of the policy have been agreed to and the insurance policy becomes effective.

Brokerage fees – Brokerage fees represent income earned related to providing brokerage transaction services, including commissions on equity and commodity trades, and fees for investment management, advisory and administration. The performance obligations related to transaction services are executing the specified trade and are priced according to the customer’s fee schedule. Such income is recognized at a point in time as the trade occurs and the performance obligation is fulfilled. The performance obligations related to investment management, advisory and administration include allocating customer assets across a wide range of mutual funds and other investments, on-going account monitoring and re-balancing of the portfolio. These performance obligations are satisfied over time and the related revenue is calculated monthly based on the assets under management of each customer. All material performance obligations are satisfied as of the end of each accounting period.

Bankcard fees – Bankcard fees primarily represent income earned from interchange revenue from MasterCard and Visa for the Company’s processing of debit, credit, HSA, and flexible spending account transactions. Additionally, the Company earns income and incentives related to various referrals of customers to card programs. The performance obligation for interchange revenue is the processing of each transaction through the Company’s access to the banking system. This performance obligation is completed for each individual transaction and income is recognized per transaction in accordance with interchange rates established by MasterCard and Visa. The performance obligations for various referral and incentive programs include either referring customers to certain card products or issuing exclusively branded cards for certain customer segments. The pricing of these incentive and referral programs are in accordance with the agreement with the individual card partner. These performance obligations are completed as the referrals are made or over a period of time when the Company is exclusively issuing branded cards. For the three months ended March 31, 2024 and March 31, 2023, the Company had $7.9 million and $10.0 million of expense, respectively, recorded within the Bankcard fees line on the Company’s Consolidated Statements of Income related to rebates and rewards programs that are outside of the scope of ASC 606. All material performance obligations are satisfied as of the end of each accounting period.

Investment securities gains (losses), net – In the regular course of business, the Company recognizes gains and losses on the sale of available-for-sale securities. Additionally, the Company recognizes gains and losses on equity securities with readily determinable fair values and equity securities without readily determinable fair values. These gains and losses are recognized in accordance with ASC 320, Debit and Equity Securities, and are outside of the scope of ASC 606.

Other income – The Company recognizes other miscellaneous income through a variety of other revenue streams, the most material of which include letter of credit fees, certain loan origination fees, gains on the sale of assets, derivative income, and bank-owned and company-owned life insurance income. These revenue streams are outside of the scope of ASC 606 and are recognized in accordance with the applicable U.S. GAAP. The remainder of Other income is primarily earned through transactions with personal banking customers, including wire transfer service charges, stop payment charges, and fees for items like money orders and cashier’s checks. The performance obligations of these types of fees are satisfied as transactions are completed and revenue is recognized upon transaction execution according to established fee schedules with the customers.

42

The Company had no material contract assets, contract liabilities, or remaining performance obligations as of March 31, 2024. Total receivables from revenue recognized under the scope of ASC 606 were $89.7 million and $86.6 million as of March 31, 2024 and December 31, 2023, respectively. These receivables are included as part of the Other assets line on the Company’s Consolidated Balance Sheets.

The following tables depict the disaggregation of revenue according to revenue stream and Business Segment for the three months ended March 31, 2024 and March 31, 2023. As stated in Note 8, “Business Segment Reporting,” for comparability purposes, amounts in all periods are based on methodologies in effect at March 31, 2024 and previously reported results have been reclassified in this Form 10-Q to conform to the Company’s current organizational structure.

10. Commitments, Contingencies and Guarantees

In the normal course of business, the Company is a party to financial instruments with off-balance-sheet risk in order to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, commercial letters of credit, standby letters of credit, and futures contracts. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheets. The contractual or notional amount of those instruments reflects the extent of involvement the Company has in particular classes of financial instruments. Many

43

of the commitments expire without being drawn upon; therefore, the total amount of these commitments does not necessarily represent the future cash requirements of the Company.

The Company’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instruments for commitments to extend credit, commercial letters of credit, and standby letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.

The following table summarizes the Company’s off-balance sheet financial instruments as described above (in thousands):

	Contractual or Notional Amount
	March 31,		December 31,
	2024		2023
Commitments to extend credit for loans (excluding credit card loans)	$	12,687,851	$	12,831,831
Commitments to extend credit under credit card loans		5,298,162		4,286,604
Commercial letters of credit		885		1,224
Standby letters of credit		431,331		407,574
Forward contracts		40,215		26,471
Spot foreign exchange contracts		74,984		4,830
Commitments to extend credit for securities purchased under agreements to resell		300,000		—

Allowance for Credit Losses on Off-Balance Sheet Credit Exposure

The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancelable by the Company. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The estimate is based on expected utilization rates by portfolio segment. Utilization rates are influenced by historical trends and current conditions. The expected utilization rates are applied to the total commitment to determine the expected amount to be funded. The allowance for off-balance sheet credit exposure is calculated by applying portfolio segment expected credit loss rates to the expected amount to be funded.

The following categories of off-balance sheet credit exposures have been identified:

Revolving Lines of Credit: includes commercial, construction, agricultural, personal, and home-equity. Risks inherent to revolving lines of credit often are related to the susceptibility of an individual or business experiencing unpredictable cash flow or financial troubles, thus leading to payment default. During these financial troubles, the borrower could have less than desirable assets collateralizing the revolving line of credit. The financial strain the borrower is experiencing could lead to drawing against the line without the ability to pay the line down.

Non-Revolving Lines of Credit: includes commercial and personal. Lines that do not carry a revolving feature are generally associated with a specific expenditure or project, such as to purchase equipment or the construction of real estate. The predominate risk associated with non-revolving lines is the diversion of funds for other expenditures. If the funds get diverted, the contributory value to collateral suffers.

Letters of Credit: includes standby letters of credit. Generally, a standby letter of credit is established to provide assurance to the beneficiary that the applicant will perform certain obligations arising out of a separate transaction between the beneficiary and the applicant. These obligations might be the performance of a service or delivery of a product. If the obligations are not met, it gives the beneficiary the right to draw on the letter of credit.

The ACL for off-balance sheet credit exposures was $5.1 million as of both March 31, 2024 and December 31, 2023, and was recorded in the Accrued expenses and taxes line of the Company’s Consolidated Balance Sheets. There was no provision for off-balance sheet credit exposures recorded for the three months ended

44

March 31, 2024 or March 31, 2023. Provision for off-balance sheet credit exposures is recorded in the Provision for credit losses line of the Company’s Consolidated Statements of Income.

11. Derivatives and Hedging Activities

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s loans and borrowings. The Company also has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk of the Company’s assets or liabilities. The Company has entered into an offsetting position for each of these derivative instruments with a matching instrument from another financial institution in order to minimize its net risk exposure resulting from such transactions.

Fair Values of Derivative Instruments on the Consolidated Balance Sheets

The table below presents the fair value of the Company’s derivative financial instruments as of March 31, 2024 and December 31, 2023. The Company’s derivative assets and derivative liabilities are located within Other assets and Other liabilities, respectively, on the Company’s Consolidated Balance Sheets.

Derivative fair values are determined using valuation techniques including discounted cash flow analysis on the expected cash flows from each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

This table provides a summary of the fair value of the Company’s derivative assets and liabilities as of March 31, 2024 and December 31, 2023 (in thousands):

	Derivative Assets				Derivative Liabilities
	March 31,		December 31,		March 31,		December 31,
Fair Value	2024		2023		2024		2023
Interest Rate Products:
Derivatives not designated as hedging instruments	$	113,585	$	99,574	$	119,491	$	105,016
Derivatives designated as hedging instruments		107,328		61,922		38		67
Total	$	220,913	$	161,496	$	119,529	$	105,083

45

Fair Value Hedges of Interest Rate Risk

The Company is exposed to changes in the fair value of certain of its fixed-rate assets and liabilities due to changes in interest rates. Interest rate swaps designated as fair value hedges involve making fixed rate payments to a counterparty in exchange for the Company receiving variable rate payments over the life of the agreements without the exchange of the underlying notional amount. As of both March 31, 2024 and December 31, 2023, the Company did not have any interest rate swaps that were designated as fair value hedges of interest rate risk.

During 2022 and 2023, the Company terminated 10 fair value hedges of interest rate risk associated with the Company's municipal bond securities. For the three months ended March 31, 2024 and 2023 the Company reclassified $2.6 million and $1.1 million, respectively, from AOCI to Interest income in connection with these terminated hedges. The unrealized gain on the terminated fair value hedges remaining in AOCI was $53.0 million net of tax, and $55.0 million net of tax, as of March 31, 2024 and December 31, 2023, respectively. The hedging adjustments will be amortized through the contractual maturity date of each respective hedged item.

For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in Interest income in the Consolidated Statements of Income.

Cash Flow Hedges of Interest Rate Risk

The Company’s objective in using interest rate derivatives is to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps, floors, and floor spreads as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. As of March 31, 2024 and December 31, 2023, the Company had two interest rate swaps that were designated as cash flow hedges of interest rate risk associated with the Company’s variable-rate subordinated debentures issued by Marquette Capital Trusts III and IV. These swaps had an aggregate notional amount of $51.5 million at both March 31, 2024 and December 31, 2023.

Interest rate floors designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates fall below the strike rate on the contract in exchange for an upfront premium. Interest rate floor spreads designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates fall below the purchased floor rate on the contract in exchange for an upfront premium, and involve payment of variable-rate amounts to the counterparty if interest rates fall below the sold floor rate on the contract. As of March 31, 2024, the Company had eight interest rate floors and floor spreads with an aggregate notional amount of $2.0 billion that were designated as cash flow hedges of interest rate risk. As of December 31, 2023, the Company had three interest rate floors and floor spreads with an aggregate notional amount of $1.0 billion that were designated as cash flow hedges of interest rate risk.

In 2020, the Company terminated an interest rate floor designated as a cash flow hedge. The gross unrealized gain on the terminated interest rate floor remaining in AOCI was $1.2 million net of tax, and $2.0 million net of tax, as of March 31, 2024 and December 31, 2023, respectively. The unrealized gain will be reclassified into Interest income as the underlying forecasted transactions impact earnings through the original maturity of the hedged forecasted transactions.

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and is subsequently reclassified into interest expense and interest income in the period during which the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to interest rate swap derivatives will be reclassified to Interest expense as interest payments are received or paid on the Company’s hedged items. Amounts reported in AOCI related to interest rate floor and floor spread derivatives will be reclassified to Interest income as interest payments are received or paid on the Company’s hedged items. The Company expects to reclassify $1.2 million from AOCI as a reduction to Interest expense and $1.9 million from AOCI as a reduction to Interest income during the next 12 months. As of March 31, 2024, the Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a maximum period of 12.5 years.

46

Non-designated Hedges

The remainder of the Company’s derivatives are not designated in qualifying hedging relationships. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously offset by interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The changes in the fair value of both the customer swaps and the offsetting swaps are recognized in Other noninterest expense in the Consolidated Statements of Income. As of March 31, 2024, the Company had 268 interest rate swaps with an aggregate notional amount of $4.7 billion related to this program. As of December 31, 2023, the Company had 258 interest rate swaps with an aggregate notional amount of $4.3 billion.

Credit-risk-related Contingent Features

The Company has agreements with certain of its derivative counterparties that contain a provision that if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations.

The Company has minimum collateral posting thresholds with certain of its derivative counterparties. At March 31, 2024, the Company had not posted any collateral as there were no derivatives in a net liability position. If the Company had breached any of these provisions at March 31, 2024, it could have been required to settle its obligations under the agreements at the termination value.

12. Fair Value Measurements

The following table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2024, and December 31, 2023, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value.

Fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets and liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the fair value is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Valuation methods for instruments measured at fair value on a recurring basis

The following methods and assumptions were used to estimate the fair value of each class of financial instruments measured on a recurring basis:

Trading Securities Fair values for trading securities (including financial futures), are based on quoted market prices where available. If quoted market prices are not available, fair values are based on quoted market prices for similar securities.

Securities Available for Sale Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Prices are provided by third-party pricing services and are based on observable market inputs. On an annual basis, the Company compares a sample of these prices to other independent sources for the same securities. Additionally, throughout the year, if securities are sold, comparisons are made between the pricing services prices and the market prices at which the securities were sold. Variances are analyzed, and, if appropriate, additional research is conducted with the third-party pricing services. Based on this research, the pricing services may affirm or revise their quoted price. No significant adjustments have been made to the prices provided by the pricing services. The pricing services also provide documentation on an ongoing basis that includes reference data, inputs and methodology by asset class, which is reviewed to ensure that security placement within the fair value hierarchy is appropriate.

Equity securities with readily determinable fair values Fair values are based on quoted market prices.

Company-owned Life Insurance Fair value is equal to the cash surrender value of the life insurance policies.

50

Bank-owned Life Insurance Fair value is equal to the cash surrender value of the life insurance policies.

Derivatives Fair values are determined using valuation techniques including discounted cash flow analysis on the expected cash flows from each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Securities sold not yet purchased Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Prices are provided by third-party pricing services and are based on observable market inputs.

Valuation methods for instruments measured at fair value on a non-recurring basis

The following methods and assumptions were used to estimate the fair value of each class of financial instruments measured on a non-recurring basis:

Collateral Dependent Assets Collateral dependent assets are assets evaluated as part of the ACL on an individual basis. Those assets for which there is an associated allowance are considered financial assets measured at fair value on a non-recurring basis. Adjustments are recorded on certain assets to reflect write-downs that are based on the external appraised value of the underlying collateral. The external appraisals are generally based on recent sales of comparable properties which are then adjusted for the unique characteristics of the property being valued. In the case of non-real estate collateral, reliance is placed on a variety of sources, including external estimates of value and judgments based on the experience and expertise of internal specialists within the Company’s property management group and the Company’s credit department. The valuation of collateral dependent assets and impaired

51

loans are reviewed on a quarterly basis. Because many of these inputs are not observable, the measurements are classified as Level 3.

Other real estate owned Other real estate owned consists of loan collateral which has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate and other non-real estate property, including auto, recreational and marine vehicles. Other real estate owned is recorded as held for sale initially at the fair value of the collateral less estimated selling costs. The initial valuation of the foreclosed property is obtained through an appraisal process similar to the process described in the collateral dependent/impaired loans paragraph above. Subsequent to foreclosure, valuations are reviewed quarterly and updated periodically, and the assets may be marked down further, reflecting a new cost basis. Fair value measurements may be based upon appraisals, third-party price opinions, or internally developed pricing methods and those measurements are classified as Level 3.

Fair value disclosures require disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis.

The estimated fair value of the Company’s financial instruments at March 31, 2024 and December 31, 2023 are as follows (in thousands):

Cash and short-term investments The carrying amounts of cash and due from banks, federal funds sold and resell agreements are reasonable estimates of their fair values.

Securities held to maturity For U.S. Agency and mortgage-backed securities, as well as general obligation bonds in the State and political subdivision portfolio, fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Prices are provided by third-party pricing services and are based on observable market inputs. On an annual basis, the Company compares a sample of these prices to other independent sources for the same securities. Variances are analyzed, and, if appropriate, additional research is conducted with the third-party pricing services. Based on this research, the pricing services may affirm or revise their quoted price. No significant adjustments have been made to the prices provided by the pricing services. The pricing services also provide documentation on an ongoing basis that includes reference data, inputs and methodology by asset class, which is reviewed to ensure that security placement within the fair value hierarchy is appropriate. For private placement bonds in the State and political subdivision portfolio, fair values are estimated by discounting the future cash flows using current market rates.

Other securities Amount consists of FRB and FHLB stock held by the Company, equity securities with readily determinable fair values, and equity securities without readily determinable fair values, including equity-method investments and other miscellaneous investments. The carrying amount of the FRB and FHLB stock equals its fair value because the shares can only be redeemed by the FRB and FHLB at their carrying amount. Equity securities with readily determinable fair values are measured at fair value using quoted market prices. Equity securities without readily determinable fair values are carried at cost, which approximates fair value.

Loans Fair values are estimated for portfolios with similar financial characteristics. Loans are segregated by type, such as commercial, real estate, consumer, and credit card. Each loan category is further segmented into fixed and variable interest rate categories. The fair value of loans is estimated by discounting the future cash flows. The

53

discount rates used are estimated using comparable market rates for similar types of instruments adjusted to be commensurate with the credit risk, overhead costs, and optionality of such instruments.

Demand and savings deposits The fair value of demand deposits and savings accounts was the amount payable on demand at period-end.

Time deposits The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using the rates that are currently offered for deposits of similar remaining maturities.

Other borrowings The carrying amounts of federal funds purchased, repurchase agreements and other short-term debt are reasonable estimates of their fair value because of the short-term nature of their maturities. Federal funds purchased are classified as Level 1 based on availability of quoted market prices and repurchase agreements and other short-term debt are classified as Level 2.

Long-term debt Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate fair value of existing debt.

Other off-balance sheet instruments The fair value of loan commitments and letters of credit are determined based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the present creditworthiness of the counterparties. Neither the fees earned during the year on these instruments nor their fair value at period-end are significant to the Company’s consolidated financial position.

13. Subsequent Event

On April 29, 2024, the Company announced that it had entered into a definitive merger agreement with Heartland Financial USA, Inc. (HTLF), headquartered in Denver, CO, under which the Company will acquire HTLF in an all-stock transaction with a total market value of approximately $2.0 billion. Under the terms of the merger agreement, HTLF stockholders will receive a fixed exchange ratio of 0.55 shares of the Company’s common stock for each share of HTLF common stock.

The merger has been approved by the board of directors of each company and will close subject to the satisfaction of customary closing conditions, including the receipt of regulatory approval and approval by the shareholders of the Company and HTLF.

In a press release dated April 29, 2024, HTLF preliminarily reported total assets of approximately $19.1 billion, including loans of $11.6 billion, and deposits of $15.3 billion.

On April 29, 2024, the Company also announced that in connection with the execution of the merger agreement, it entered into a forward sale agreement with BofA Securities, Inc. or its affiliate to issue 2,800,000 shares of its common stock for approximate proceeds of $201.6 million. The underwriters were granted an option to purchase up to an additional 420,000 shares of the Company's common stock exercisable within 30 days of April 28, 2024. The underwriters exercised this option in full on April 30, 2024, upon which the Company entered into an additional forward sale agreement relating to the 420,000 shares of the Company's common stock. The forward purchase agreement is classified as an equity instrument under ASC 815-40, Contracts in Entity’s Own Equity.

Overview

The rapid rise in interest rates during 2022 and 2023, the resulting industry-wide reduction in the fair value of securities portfolios, and the bank runs that led to the failures of some financial institutions in March of 2023, among other events, have resulted in significant volatility in the U.S. banking sector and heightened focus on liquidity, uninsured deposits, deposit composition, unrecognized investment losses, and capital.

During November 2023, the Federal Deposit Insurance Corporation (the FDIC) approved a final rule to implement a special assessment to recover the losses to the Deposit Insurance Fund (the DIF) associated with protecting uninsured depositors following the closures of certain financial institutions in March of 2023. The assessment base for the special assessment is equal to an insured depository institution’s uninsured deposits as of December 31, 2022, adjusted to exclude the first $5 billion, and will be collected at an annual rate of 13.4 basis points for eight quarterly assessment periods. The Company’s portion of this special assessment was $52.8 million and was recognized in noninterest expense during the fourth quarter of 2023. During February 2024, the FDIC increased the estimated loss attributable to the 2023 bank failures by 25%, which in turn increased the special assessment the FDIC will charge to insured depository institutions. The Company recorded $13.0 million of expense related to the updated special assessment in the first quarter of 2024 and its impacts are discussed below.

The Company focuses on the following four core financial objectives. Management believes these objectives will guide its efforts to achieve its vision, to deliver the Unparalleled Customer Experience, all while seeking to improve net income and strengthen the balance sheet while undertaking prudent risk management.

The first financial objective is to continuously improve operating efficiencies. The Company has focused on identifying efficiencies that simplify our organizational and reporting structures, streamline back-office functions, and take advantage of synergies and newer technologies among various platforms and distribution networks. The Company has identified and expects to continue identifying ongoing efficiencies through the normal course of business that, when combined with increased revenue, will contribute to improved operating leverage. During the first quarter of 2024, total revenue increased $26.8 million, or 7.2%, as compared to the first quarter of 2023, while noninterest expense increased $17.8 million, or 7.5%, for the same period. As part of the initiative to improve operating efficiencies, the Company continues to invest in technological advances that it believes will help management drive operating leverage in the future through improved data analysis and automation. The Company also continues to evaluate core systems and will invest in enhancements that it believes will yield operating efficiencies.

The second financial objective is to increase net interest income through profitable loan and deposit growth and the optimization of the balance sheet. During the first quarter of 2024, the Company had a decrease in net interest income of $2.3 million, or 0.9%, from the same period in 2023. The change in net interest income was driven by higher interest expense due to an unfavorable mix shift in the composition of liabilities, partially offset by increased loan growth. These changes are driven by the higher interest rate environment compared to the first quarter of 2023. The increase in interest income was driven by a $2.1 billion, or 9.8%, increase in average loans and a $1.8 billion, or 115.4%, increase in average interest-bearing due from banks, coupled with the impact of higher short-term and long-term interest rates. The funding for these assets was driven primarily by a 20.3% increase in average interest-bearing liabilities, including an increase in average borrowed funds of $983.1 million compared to the same period in 2023. Net interest margin, on a tax-equivalent basis, decreased 28 basis points compared to the same period in 2023, primarily due to increased cost and mix of interest-bearing liabilities, partially offset by increased loan volumes, repricing of earning assets, and the benefit of interest free funds. Net interest spread contracted by 43 basis points during the same period. The Company expects to see continued volatility in the economic markets resulting from governmental responses to inflation and recessionary signs in the economy. These changing conditions could have impacts on the balance sheet and income statement of the Company for the remainder of the year.

The third financial objective is to grow the Company’s revenue from noninterest sources. The Company seeks to grow noninterest revenues throughout all economic and interest rate cycles, while positioning itself to benefit in periods of economic growth. Noninterest income increased $29.0 million, or 22.3%, to $159.2 million for the three months ended March 31, 2024, compared to the same period in 2023. This change is primarily due to increases in investment securities gains, trust and securities processing income, other income and bankcard income.

57

See greater detail below under Noninterest Income. The Company continues to emphasize its asset management, brokerage, bankcard services, healthcare services, and treasury management businesses. For the three-month period ended March 31, 2024, noninterest income represented 39.9% of total revenues, compared to 35.0% for the same period in 2023. The recent economic changes have impacted fee income, especially those with assets tied to market values and interest rates.

The fourth financial objective is effective capital management. The Company places a significant emphasis on maintaining a strong capital position, which management believes promotes investor confidence, provides access to funding sources under favorable terms, and enhances the Company’s ability to capitalize on business growth and acquisition opportunities. The Company continues to maximize shareholder value through a mix of reinvesting in organic growth, evaluating acquisition opportunities that complement the Company’s strategies, increasing dividends over time, and appropriately utilizing a share repurchase program. At March 31, 2024, the Company had $3.2 billion in total shareholders’ equity. This is an increase of $338.2 million, or 12.0%, compared to total shareholders’ equity at March 31, 2023. At March 31, 2024, the Company had a total risk-based capital ratio of 13.03%. The Company did not repurchase shares of common stock during the first quarter of 2024, except for shares acquired pursuant to the Company's share-based incentive programs.

Earnings Summary

The following is a summary regarding the Company’s earnings for the first quarter of 2024. The changes identified in the summary are explained in greater detail below. The Company recorded net income of $110.3 million for the three-month period ended March 31, 2024, compared to net income of $92.4 million for the same period a year earlier. Basic earnings per share for the first quarter of 2024 was $2.27 per share ($2.25 per share fully-diluted) compared to basic earnings per share of $1.91 per share ($1.90 per share fully-diluted) for the first quarter of 2023. Return on average assets and return on average common shareholders’ equity for the three-month period ended March 31, 2024 were 1.06% and 14.11%, respectively, compared to 0.97% and 13.76%, respectively, for the three-month period ended March 31, 2023.

Net interest income for the three-month period ended March 31, 2024 decreased $2.3 million, or 0.9%, compared to the same period in 2023. For the three-month period ended March 31, 2024, average earning assets increased $3.4 billion, or 9.4%, compared to the same period in 2023. Net interest margin, on a tax-equivalent basis, decreased to 2.48% for the three-month period ended March 31, 2024, compared to 2.76% for the same period in 2023.

The provision for credit losses decreased by $13.3 million for the three-month period ended March 31, 2024, as compared to the same period in 2023. Provision expense for both periods is primarily impacted by macro-economic data and portfolio credit metrics. The Company’s nonperforming loans increased $2.3 million to $17.8 million at March 31, 2024, compared to March 31, 2023. The ACL on loans as a percentage of total loans decreased to 0.96% as of March 31, 2024, compared to 0.97% at March 31, 2023. For a description of the Company’s methodology for computing the ACL, please see the summary discussion in the “Provision and Allowance for Credit Losses” section included below.

Noninterest income increased by $29.0 million, or 22.3%, for the three-month period ended March 31, 2024, compared to the same period in 2023. These changes are discussed in greater detail below under Noninterest Income.

Noninterest expense increased by $17.8 million, or 7.5%, for the three-month period ended March 31, 2024, compared to the same period in 2023. These changes are discussed in greater detail below under Noninterest Expense.

Net Interest Income

Net interest income is a significant source of the Company’s earnings and represents the amount by which interest income on earning assets exceeds the interest expense paid on liabilities. The volume of interest-earning assets and the related funding sources, the overall mix of these assets and liabilities, and the rates paid on each affect

58

net interest income. Net interest income for the three-month period ended March 31, 2024 decreased $2.3 million, or 0.9%, compared to the same period in 2023.

Table 1 shows the impact of earning asset rate changes compared to changes in the cost of interest-bearing liabilities. As illustrated in this table, net interest spread for the three months ended March 31, 2024 decreased 43 basis points as compared to the same period in 2023. Net interest margin for the three months ended March 31, 2024 decreased 28 basis points compared to the same period in 2023. The changes are primarily due to increased cost and mix of interest-bearing liabilities, partially offset by increased loan volumes and repricing of earning assets. The impact of the increased cost and mix of interest-bearing liabilities had a significant impact in the first quarter of 2024. The cost of interest-bearing liabilities increased 112 basis points from the first quarter of 2023 while the yield on earning assets increased 69 basis points compared to the same period. Earning asset balance increases have been primarily driven by higher average loan and interest-bearing due from bank balances. These variances have led to a decrease in the Company’s net interest income during 2024, as compared to results for the same period in 2023. The Company expects to see continued volatility in the economic markets and governmental responses to changes in the economy. These changing conditions could have impacts on the balance sheet and income statement of the Company the remainder of the year. For the impact of the contribution from free funds, see the Analysis of Net Interest Margin within Table 2 below. Table 2 also illustrates how the changes in volume and interest rates have resulted in an increase in net interest income.

Table 2 presents the dollar amount of change in net interest income and margin due to volume and rate. Table 2 also reflects the effect that interest-free funds have on net interest margin. The average balance of interest-free funds (total earning assets less interest-bearing liabilities) decreased $1.3 billion for the three-month period ended March 31, 2024, compared to the same period in 2023. The benefit from interest-free funds increased 15 basis points in the three-month period ended March 31, 2024 compared to the same period in 2023.

Provision and Allowance for Credit Losses

The ACL represents management’s judgment of the total expected losses included in the Company’s loan portfolio as of the balance sheet date. The Company’s process for recording the ACL is based on the evaluation of the Company’s lifetime historical loss experience, management’s understanding of the credit quality inherent in the loan portfolio, and the impact of the current economic environment, coupled with reasonable and supportable economic forecasts.

A mathematical calculation of an estimate is made to assist in determining the adequacy and reasonableness of management’s recorded ACL. To develop the estimate, the Company follows the guidelines in ASC 326, Financial Instruments – Credit Losses. The estimate reserves for assets held at amortized cost and any related credit deterioration in the Company’s available-for-sale debt security portfolio. Assets held at amortized cost include the Company’s loan book and held-to-maturity security portfolio.

The process involves the consideration of quantitative and qualitative factors relevant to the specific segmentation of loans. These factors have been established over decades of financial institution experience and

61

include economic observation and loan loss characteristics. This process is designed to produce a lifetime estimate of the losses, at a reporting date, that includes evaluation of historical loss experience, current economic conditions, reasonable and supportable forecasts, and the qualitative framework outlined by the Office of the Comptroller of the Currency in the published 2020 Interagency Policy Statement. This process allows management to take a holistic view of the recorded ACL reserve and ensure that all significant and pertinent information is considered.

The Company considers a variety of factors to ensure the safety and soundness of its estimate including a strong internal control framework, extensive methodology documentation, credit underwriting standards which encompass the Company’s desired risk profile, model validation, and ratio analysis. If the Company’s total ACL estimate, as determined in accordance with the approved ACL methodology, is either outside a reasonable range based on review of economic indicators or by comparison of historical ratio analysis, the ACL estimate is an outlier and management will investigate the underlying reason(s). Based on that investigation, issues or factors that previously had not been considered may be identified in the estimation process, which may warrant adjustments to estimated credit losses.

The ending result of this process is a recorded consolidated ACL that represents management’s best estimate of the total expected losses included in the loan portfolio, held-to-maturity securities, and credit deterioration in available-for-sale securities.

Based on the factors above, management of the Company recorded $10.0 million as provision for credit losses for the three-month period ended March 31, 2024, compared to $23.3 million for the same period in 2023. This change is the result of applying the methodology for computing the allowance for credit losses, coupled with the impacts of the current and forecasted economic environment. As illustrated in Table 3 below, the ACL on loans decreased to 0.96% of total loans as of March 31, 2024, compared to 0.97% of total loans as of March 31, 2023.

Table 3 presents a summary of the Company’s ACL for the three-month periods ended March 31, 2024 and 2023, and for the year ended December 31, 2023. Net charge-offs were $3.0 million for the three-month period ended March 31, 2024, compared to $4.6 million for the same period in 2023. See “Credit Risk Management” under “Item 3. Quantitative and Qualitative Disclosures About Market Risk” in this report for information relating to nonaccrual loans, past due loans, restructured loans and other credit risk matters.

Noninterest Income

A key objective of the Company is the growth of noninterest income to provide a diverse source of revenue not directly tied to interest rates. Fee-based services are typically non-credit related and are not generally affected by fluctuations in interest rates.

The Company offers multiple fee-based products and services, which management believes will more closely align with customer demands. The Company is currently emphasizing fee-based products and services including trust and securities processing, bankcard, securities trading and brokerage, and cash and treasury management. Management believes that it can offer these products and services both efficiently and profitably, as most have common platforms and support structures.

Total noninterest income	$	159,244	$	130,200		$	29,044			22.3	%

Noninterest income increased by $29.0 million, or 22.3%, during the three-month period ended March 31, 2024, compared to the same period in 2023. Table 4 above summarizes the components of noninterest income and the respective year-over-year comparison for each category.

Trust and securities processing income consists of fees earned on personal and corporate trust accounts, custody of securities services, trust investments and wealth management services, mutual fund assets, and alternative asset servicing. The increase in these fees for the three-month period ended March 31, 2024, compared to the same period in 2023, was primarily due to an increase in fund services revenue, trust services income, and corporate trust revenue. For the three-month period ended March 31, 2024, fund services revenue increased $5.0 million, or 14.5%, trust services income increased $1.1 million, or 8.3%, and corporate trust revenue increased $1.0 million, or 6.8%, in each case compared to the same period in 2023. The recent volatile markets have impacted the income in this category. Since trust and securities processing fees are primarily asset-based, which are highly correlated to the change in market value of the assets, the related income for the remainder of the year will be affected by changes in the securities markets. Management continues to emphasize sales of services to both new and existing clients as well as increasing and improving the distribution channels.

Bankcard fees for the three-month period ended March 31, 2024 increased $3.8 million, or 20.9%, compared to the same period in 2023. This increase was driven by higher interchange income, coupled with lower rebate and reward costs.

Investment securities gains, net for the three-month period ended March 31, 2024 increased by $14.7 million, or 276.0%, compared to the same period in 2023. This increase was driven by a $10.7 million gain on disposition of one of the Company's securities without readily determinable fair value, coupled with the $4.8 million impairment of an available-for-sale subordinated debt security during the first quarter of 2023. The income in this category is highly correlated to the change in market value of the assets, and the related income for the remainder of the year will be affected by changes in the securities markets. The Company’s investment portfolio is continually evaluated for opportunities to improve its performance and risk profile relative to market conditions and the Company’s interest rate expectations. This can result in differences from quarter to quarter in the amount of realized gains or losses on this portfolio.

Other noninterest income for the three-month period ended March 31, 2024 increased $4.2 million, or 28.7%, compared to the same period in 2023, driven by a $4.0 million legal settlement and a $1.8 million gain on sale of land, both recorded in the first quarter of 2024. These increases were partially offset by a decrease of $2.4 million in derivative income.

Noninterest expense increased by $17.8 million, or 7.5%, for the three-month period ended March 31, 2024, compared to the same period in 2023. Table 5 above summarizes the components of noninterest expense and the respective year-over-year comparison for each category.

Processing fees increased $4.7 million, or 20.2%, for the three-month period ended March 31, 2024, compared to the same period in 2023, primarily due to increased software subscription cost.

Bankcard expense increased $3.4 million, or 48.1%, for the three-month period ended March 31, 2024, compared to the same period in 2023, primarily due to higher administrative expenses and fraud losses.

Regulatory fees increased $13.8 million, or 249.4%, for the three-month period ended March 31, 2024, compared to the same period in 2023, primarily due to the $13.0 million FDIC special assessment recorded in the first quarter of 2024 as discussed above.

Income Tax Expense

The Company’s effective tax rate was 17.6% for the three months ended March 31, 2024, compared to 17.2% for the same period in 2023.

Strategic Lines of Business

The Company has strategically aligned its operations into the following three reportable Business Segments: Commercial Banking, Institutional Banking, and Personal Banking.

For the three-month period ended March 31, 2024, Commercial Banking net income increased $25.8 million to $83.1 million, as compared to the same period in 2023. Net interest income increased $6.2 million, or 4.1%, for the three-month period ended March 31, 2024, compared to the same period in 2023, primarily driven by strong loan growth, earning asset mix changes and the increase in short-term interest rates. Provision for credit losses decreased $13.5 million for the period, driven by portfolio metric changes and changes in macro-economic metrics in 2024 as compared to 2023, partially offset by loan growth. Noninterest income increased $20.1 million, or 87.6%, compared to the same period in 2023, primarily due to an increase of $10.7 million in investment securities gains, an increase of $4.7 million in miscellaneous income driven by a legal settlement in the first quarter of 2024, an increase of $2.4 million in bankcard fees, and an increase of $1.8 million in service charges on deposit accounts. Noninterest expense increased $8.4 million, or 10.0%, to $92.4 million for the three-month period ended March 31, 2024, compared to the same period in 2023. This increase was driven by a $7.4 million increase in regulatory fees driven by the FDIC special assessment in the first quarter of 2024, and an increase of $1.5 million in salaries and employee benefits expense.

For the three-month period ended March 31, 2024, Institutional Banking net income decreased $7.3 million, or 17.6%, compared to the same period last year. Net interest income decreased $5.2 million, or 9.5%, compared to the same period last year, due to higher deposit interest expense driven by the increase in short-term interest rates. Noninterest income increased $8.5 million, or 10.1%, primarily due to increases of $6.1 million in trust and securities processing income driven by higher fund services and corporate trust revenue, and $1.8 million in bankcard fees primarily driven by higher interchange income. Noninterest expense increased $11.0 million, or 12.3%, primarily driven by increases of $6.2 million in regulatory fees driven by the FDIC special assessment in the first quarter of 2024, $2.7 million in salaries and employee benefits expense, $1.7 million in processing fees, $1.6 million in bankcard expense, and $1.0 million in equipment expense. These increases were partially offset by a decrease of $1.3 million in technology, service, and overhead expenses.

Net interest income decreased $3.3 million, or 9.2%, compared to the same period last year due to higher deposit interest expense driven by the increase in short-term interest rates. Provision for credit losses decreased $0.1 million for the period driven by portfolio metric changes and changes in macro-economic metrics in 2024 as compared to 2023, partially offset by loan growth. Noninterest income increased $0.5 million, or 2.2%, for the same period driven by an increase of $1.1 million in trust and securities processing income, an increase of $1.0 million in miscellaneous other income primarily due to the gain on sale of land during the first quarter of 2024, partially offset by a decrease of $1.3 million in investment securities gains. Noninterest expense decreased $1.7 million, or 2.6%, primarily due to a decrease of $2.0 million in technology, service, and overhead expenses, and a decrease of $1.6 million in operational losses, partially offset by increases of $1.1 million in bankcard expense and $0.5 million in marketing and business development expense.

Loans represent the Company’s largest source of interest income. In addition to growing the commercial loan portfolio, management believes its middle market commercial business and its consumer business, including home

67

equity and credit card loan products, are the market niches that represent its best opportunity to cross-sell fee-related services and generate additional noninterest income for the Company.

Actual loan balances totaled $23.6 billion as of March 31, 2024, and increased $465.2 million, or 2.0%, compared to December 31, 2023, and increased $1.8 billion, or 8.4%, compared to March 31, 2023. Compared to December 31, 2023, commercial real estate loans increased $391.2 million, or 4.4%, and credit card loans increased $114.5 million, or 27.0%. Compared to March 31, 2023, commercial real estate loans increased $1.2 billion, or 15.4%, commercial and industrial loans increased $362.7 million, or 3.8%, consumer real estate loans increased $203.8 million, or 7.4%, and credit card loans increased $92.1 million, or 20.6%. The increase in credit card loans in both periods is related to the purchase of $109.4 million in co-branded credit card receivables during the first quarter of 2024. See further information in Note 4, “Loans and Allowance for Credit Losses” in the Notes to Consolidated Financial Statements.

As of March 31, 2024 and December 31, 2023, commercial real estate loans comprised approximately 39.3% and 38.4%, respectively, of the Company's loan portfolio. Commercial real estate loans generally involve a greater degree of credit risk than consumer real estate loans because they typically have larger balances and are more affected by adverse conditions in the economy. Because payments on loans secured by commercial real estate often depend upon the successful operation and management of the properties and the businesses which operate from within them, repayment of such loans may be affected by factors outside the borrower’s control, such as adverse conditions in the real estate market or the economy or changes in government regulations. In recent years, commercial real estate markets have been particularly impacted by the economic disruption resulting from the COVID-19 pandemic. The COVID-19 pandemic has also been a catalyst for the evolution of various remote work options, which could impact the long-term performance of some types of office properties within our commercial real estate portfolio. Due to these risks, the Company is actively monitoring its exposure to commercial real estate.

Generally, these loans are made for investment and real estate development or working capital and business expansion purposes and are primarily secured by real estate with a maximum loan-to-value of 80%. Most of these properties are non-owner occupied and have guarantees as additional security. The Company's investment CRE portfolio (which includes non-owner occupied and construction loans) totaled 27.8% and 26.5% of total Company loans as of March 31, 2024 and December 31, 2023, respectively. The average investment CRE loan was approximately $6.3 million and $5.8 million, as of March 31, 2024 and December 31, 2023, respectively, and 90% are recourse loans as of the end of each period. These loans have an average loan-to-value of 57% as of both March 31, 2024 and December 31, 2023.

The properties securing the commercial real estate portfolio are diverse in terms of type and geographic location. This diversity helps reduce exposure to adverse economic events that affect any single market or industry. Notwithstanding, commercial real estate loans, in general, may be more adversely impacted by conditions in the real estate market or the economy.

The following table presents the Company's investment CRE (which includes non-owner occupied and construction loans) by industry. The table separately discloses the top five industries as a percentage of the Company's loan portfolio as of either period presented, while the remainder are included in "Other."

The shift to work-from-home and hybrid work environments has caused a decreased utilization of, and demand for, office space. The Company is actively monitoring its exposure to office space in its non-owner occupied commercial real estate portfolio. The average loan size in the Company's office portfolio was approximately $9.0 million and $9.2 million, as of March 31, 2024 and December 31, 2023, respectively. The average loan-to-value of the office portfolio was 64% as of both March 31, 2024 and December 31, 2023, and 84% are recourse loans as of the end of both periods. Further, only 24% and 30% of the Company's office portfolio as of March 31, 2024 and December 31, 2023, respectively, is in central business districts, which have been more heavily impacted by the shift to remote work. The remainder of the Company's office portfolio is in suburban or medical properties.

Investment Securities

The Company’s investment portfolio contains trading, AFS, and HTM securities, as well as FRB stock, FHLB stock, and other miscellaneous investments. Investment securities totaled $12.7 billion as of March 31, 2024, and

69

$13.3 billion as of December 31, 2023, and comprised 29.4% and 31.9% of the Company’s earning assets, respectively, as of those dates.

The Company’s AFS securities portfolio comprised 51.6% of the Company’s investment securities portfolio at March 31, 2024 and 53.3% at December 31, 2023. The Company’s AFS securities portfolio provides liquidity as a result of the composition and average life of the underlying securities. This liquidity can be used to fund loan growth or to offset the outflow of traditional funding sources. The average life of the AFS securities portfolio was 57.8 months at March 31, 2024, compared to 52.6 months at December 31, 2023, and 59.8 months at March 31, 2023. In addition to providing a potential source of liquidity, the AFS securities portfolio can be used as a tool to manage interest rate sensitivity. The Company’s goal in the management of its AFS securities portfolio is to maximize return within the Company’s parameters of liquidity goals, interest rate risk, and credit risk.

Management expects collateral pledging requirements for public funds, loan demand, and deposit funding to be the primary factors impacting changes in the level of AFS securities. There were $9.4 billion and $10.1 billion of securities pledged to secure U.S. Government deposits, other public deposits, certain trust deposits, derivative transactions, and repurchase agreements at March 31, 2024 and December 31, 2023, respectively.

The Company’s HTM securities portfolio consists of U.S. agency-backed securities, mortgage-backed securities, general obligation bonds, and private placement bonds. The HTM portfolio, net of the ACL, totaled $5.6 billion at March 31, 2024 and $5.7 billion as of December 31, 2023. The average life of the HTM portfolio was 9.0 years at March 31, 2024, compared to 8.4 years at December 31, 2023, and 9.1 years at March 31, 2023.

The securities portfolio generates the Company’s second largest component of interest income. The securities portfolio achieved an average yield on a tax-equivalent basis of 2.88% for the three-month period ended March 31, 2024, compared to 2.61% for the same period in 2023.

At March 31, 2024, the unrealized pre-tax net loss on the AFS securities portfolio was $665.9 million, or 9.2% of the $7.2 billion amortized cost value, an increase of $41.7 million as compared to December 31, 2023. At March 31, 2024, the unrealized pre-tax net loss on the securities designated as HTM was $601.3 million, or 10.7% of amortized cost value, compared to $508.5 million at December 31, 2023. During 2022, the Company transferred securities with an amortized cost balance of $4.1 billion and a fair value of $3.8 billion from the AFS category to the HTM category. The transfer of securities was made at fair value at the time of transfer. The remaining balance of unrealized pre-tax losses related to transferred securities was $198.4 million as of March 31, 2024, and $207.2 million as of December 31, 2023, and was included in the amortized cost balance of HTM securities. See further information in Note 5, “Securities” in the Notes to Consolidated Financial Statements.

Deposits and Borrowed Funds

Deposits increased $1.1 billion, or 3.1%, from December 31, 2023 to March 31, 2024 and increased $5.0 billion, or 15.6%, from March 31, 2023 to March 31, 2024. Total noninterest-bearing deposits increased $1.1 billion and total interest-bearing deposits increased $323 thousand from December 31, 2023 to March 31, 2024. Total noninterest-bearing deposits increased $762.3 million, and interest-bearing deposits increased $4.2 billion from March 31, 2023 to March 31, 2024. Deposits can fluctuate at quarter-end due to the operational nature of our commercial and institutional clients and typical seasonal declines in public funds deposits, particularly in the first quarter. The shift from noninterest-bearing to interest-bearing is related to the recent increases in short-term and long-term interest rates. Noninterest-bearing deposits were 35.9%, 33.9%, and 39.1% of total deposits at March 31, 2024, December 31, 2023, and March 31, 2023, respectively.

Deposits represent the Company’s primary funding source for its asset base. In addition to the core deposits garnered by the Company’s retail branch structure, the Company continues to focus on its cash management services, as well as its trust and mutual fund servicing businesses, in order to attract and retain additional deposits. Management believes a strong core deposit composition is one of the Company’s key strengths given its competitive product mix.

As of March 31, 2024, there were an estimated $25.3 billion of uninsured deposits, an increase of $868.5 million as compared to December 31, 2023, and an increase of $4.0 billion as compared to March 31, 2023. Estimated uninsured deposits comprised approximately 68.4%, 68.2%, and 66.6% of total deposits as of March 31, 2024, December 31, 2023, and March 31, 2023, respectively. A portion of these uninsured deposits represent

70

affiliate deposits and collateralized deposits. Affiliate deposits represent deposit accounts owned by the wholly owned subsidiaries of UMB Financial Corporation that are on deposit at UMB Bank, n.a. Collateralized deposits are public fund deposits or corporate trust deposits that are collateralized by high quality securities within the investment portfolio. Excluding affiliate deposits of $2.0 billion and collateralized deposits of $5.4 billion, the adjusted estimated uninsured deposits were $17.9 billion as of March 31, 2024. The adjusted ratio of estimated uninsured deposits, excluding affiliate and collateralized deposits, as a percentage of total deposits was approximately 48.6% as of March 31, 2024. The adjusted ratio of estimated uninsured deposits, excluding affiliate and collateralized deposits, as a percentage of total deposits was approximately 45.3% as of December 31, 2023, and 43.1% as of March 31, 2023.

The Company participates in the IntraFi Cash Service program, which allows its customers to place deposits into the program to receive reciprocal FDIC insurance coverage. The Company had $1.2 billion, $1.2 billion, and $811.2 million of deposits in the program as of March 31, 2024, December 31, 2023, and March 31, 2023, respectively.

Long-term debt totaled $383.7 million at March 31, 2024, compared to $383.2 million as of December 31, 2023, and $381.8 million as of March 31, 2023. In September 2022, the Company issued $110.0 million in aggregate subordinated notes due in September 2032. The Company received $107.9 million, after deducting underwriting discounts and commissions and offering expenses, and used the proceeds from the offering for general corporate purposes, including, among other uses, contributing Tier 1 capital into the Bank. The subordinated notes were issued with a fixed-to-fixed rate of 6.25% and an effective rate of 6.64%, due to issuance costs, with an interest rate reset date of September 2027.

In September 2020, the Company issued $200.0 million in aggregate subordinated notes due in September 2030. The Company received $197.7 million, after deducting underwriting discounts and commissions and offering expenses, and used the proceeds from the offering for general corporate purposes, including, among other uses, contributing Tier 1 capital into the Bank. The subordinated notes were issued with a fixed-to-fixed rate of 3.70% and an effective rate of 3.93%, due to issuance costs, with an interest rate reset date of September 2025.

The remainder of the Company’s long-term debt was assumed from the acquisition of Marquette and consists of debt obligations payable to four unconsolidated trusts (Marquette Capital Trust I, Marquette Capital Trust II, Marquette Capital Trust III, and Marquette Capital Trust IV) that previously issued trust preferred securities. These long-term debt obligations have an aggregate contractual balance of $103.1 million. Interest rates on trust preferred securities are tied to the three-month term SOFR rate with spreads ranging from 133 basis points to 160 basis points and reset quarterly. The trust preferred securities have maturity dates ranging from January 2036 to September 2036.

The Company has a revolving line of credit with Wells Fargo Bank, N.A. which allows the Company to borrow up to $30.0 million for general working capital purposes. The interest rate applied to borrowed balances will be at the Company’s option either 1.40% above Term SOFR or 1.75% below the prime rate on the date of an advance. The Company pays a 0.4% unused commitment fee for unused portions of the revolving line of credit. As of March 31, 2024, the Company had no advances outstanding on this revolving line of credit.

Short-term debt totaled $1.8 billion as March 31, 2024 and consists of a $1.0 billion short-term borrowing with the FHLB of Des Moines and an $800.0 million borrowing with the BTFP. The FHLB borrowing has an interest rate of 5.04% and is due in the second quarter of 2024. The BTFP borrowing has a rate of 4.76% and is due in the first quarter of 2025. The level of borrowings could be impacted by earning asset mix changes in the Company’s balance sheet from the impacts of recent industry volatility. See further information in Note 7, “Borrowed Funds” in the Notes to Consolidated Financial Statements.

Federal funds purchased and securities sold under agreements to repurchase totaled $2.2 billion as of March 31, 2024, $2.1 billion as of December 31, 2023, and $2.2 billion at March 31, 2023. Repurchase agreements are transactions involving the exchange of investment funds by the customer for securities by the Company under an agreement to repurchase the same or similar issues at an agreed-upon price and date. The level of borrowings could be impacted by earning asset mix changes in the Company’s balance sheet from the impacts of recent industry volatility.

Capital and Liquidity

The Company places a significant emphasis on the maintenance of a strong capital position, which promotes investor confidence, provides access to funding sources under favorable terms, and enhances the Company’s ability to capitalize on business growth and acquisition opportunities. Higher levels of liquidity, however, bear corresponding costs, measured in terms of lower yields on short-term, more liquid earning assets and higher expenses for extended liability maturities. The Company manages capital for each subsidiary based upon the subsidiary’s respective risks and growth opportunities as well as regulatory requirements.

Total shareholders’ equity was $3.2 billion at March 31, 2024, a $52.4 million increase compared to December 31, 2023, and a $338.2 million increase compared to March 31, 2023. Total accumulated other comprehensive loss was $594.5 million at March 31, 2024. This is a decline of $37.6 million as compared to December 31, 2023, and an improvement of $32.2 million as compared to March 31, 2023.

The Company’s Board of Directors authorized, at its April 30, 2024 and April 26, 2022 meetings, the repurchase of up to one million shares and two million shares, respectively, of the Company’s common stock during the twelve months following each meeting (each a Repurchase Authorization). On July 25, 2023, the Company's Board of Directors approved the repurchase of up to one million shares of the Company's common stock, which terminated on April 30, 2024. During the three-month periods ended March 31, 2024 and 2023, the Company did not repurchase shares of common stock pursuant to any of its announced Repurchase Authorizations, but did acquire shares pursuant to the Company's share-based incentive programs.

At the Company’s quarterly board meeting, the Board of Directors declared a $0.39 per share quarterly cash dividend payable on July 1, 2024, to shareholders of record at the close of business on June 10, 2024.

Through the Company’s relationship with the FHLB of Des Moines, the Company owns $55.2 million of FHLB stock and has access to additional liquidity and funding sources through FHLB advances. The Company’s borrowing capacity is dependent upon the amount of collateral the Company places at the FHLB. The Company had a $1.0 billion short-term advance outstanding at FHLB of Des Moines as of March 31, 2024. Additionally, in the first quarter of 2024, the FHLB of Des Moines issued a letter of credit for $150.0 million on behalf of the Company to secure deposits. This letter of credit will expire in July 2024. The Company’s remaining borrowing capacity with the FHLB was $952.7 million as of March 31, 2024.

The Company had an $800.0 million short-term borrowing outstanding with the Federal Reserve Bank's BTFP as of March 31, 2024. As of March 31, 2024, the Company’s remaining borrowing capacity with the BTFP was $30.0 million and its remaining borrowing capacity at the Federal Reserve Discount Window was $11.0 billion.

In addition to borrowing capacity with the FHLB and at the Federal Reserve Discount Window as described above, the Company had additional liquidity of $9.5 billion available via cash, unpledged bond collateral, the federal funds market, and the IntraFi Cash Service program as of March 31, 2024.

Risk-based capital guidelines established by regulatory agencies set minimum capital standards based on the level of risk associated with a financial institution’s assets. The Company has implemented the Basel III regulatory capital rules adopted by the FRB. Basel III capital rules include a minimum ratio of common equity tier 1 capital to risk-weighted assets of 4.5% and a minimum tier 1 risk-based capital ratio of 6%. A financial institution’s total capital is also required to equal at least 8% of risk-weighted assets.

The risk-based capital guidelines indicate the specific risk weightings by type of asset. Certain off-balance sheet items (such as standby letters of credit and binding loan commitments) are multiplied by credit conversion factors to translate them into balance sheet equivalents before assigning them specific risk weightings. The Company is also required to maintain a leverage ratio equal to or greater than 4%. The leverage ratio is calculated as the ratio of tier 1 core capital to total average assets, less goodwill and intangibles.

U.S. banking agencies in December 2018 approved a final rule to address the impact of CECL on regulatory capital by allowing banking organizations the option to phase in the day-one impact of CECL until the first quarter of 2023. In March 2020, the U.S. banking agencies issued an interim final rule that provides banking organizations

72

with an alternative 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. The Company elected this alternative option instead of the one described in the December 2018 rule.

The Company's capital position as of March 31, 2024 is summarized in the table below and exceeded regulatory requirements.

Off-balance Sheet Arrangements

The Company’s main off-balance sheet arrangements are loan commitments, commercial and standby letters of credit, futures contracts and forward exchange contracts, which have maturity dates rather than payment due dates. See Note 10, “Commitments, Contingencies and Guarantees” in the Notes to Consolidated Financial Statements for detailed information on these arrangements. The level of the outstanding commitments could be impacted by volatility in the economic markets and governmental responses to inflation, geopolitical tensions, and supply chain constraints. These changing conditions could have impacts on the consolidated balance sheets of the Company for the remainder of the year.

Critical Accounting Policies and Estimates

The preparation of these Consolidated Financial Statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates and judgments, including those related to customers and suppliers, allowance for credit losses, bad debts, investments, financing operations, long-lived assets, taxes, other contingencies, and litigation. Management bases its estimates and judgments on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which have formed the basis for making such judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Under different assumptions or conditions, actual results may differ from the recorded estimates.

73

A summary of critical accounting policies is listed in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of the Form 10-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Risk Management

Market risk is a broad term for the risk of economic loss due to adverse changes in the fair value of a financial instrument. These changes may be the result of various factors, including interest rates, foreign exchange prices, commodity prices, or equity prices. Financial instruments that are subject to market risk can be classified either as held for trading or held for purposes other than trading.

The Company is subject to market risk primarily through the effect of changes in interest rates of its assets held for purposes other than trading. The following discussion of interest rate risk, however, combines instruments held for trading and instruments held for purposes other than trading because the instruments held for trading represent such a small portion of the Company’s portfolio that the interest rate risk associated with them is immaterial.

Interest Rate Risk

In the banking industry, a major risk exposure is changing interest rates. To minimize the effect of interest rate changes to net interest income and exposure levels to economic losses, the Company manages its exposure to changes in interest rates through asset and liability management within guidelines established by its Asset Liability Committee (ALCO) and approved by the Board. The ALCO is responsible for approving and ensuring compliance with asset/liability management policies, including interest rate exposure. The Company’s primary method for measuring and analyzing consolidated interest rate risk is the Net Interest Income Simulation Analysis. The Company also uses a Net Portfolio Value model to measure market value risk under various rate change scenarios and a gap analysis to measure maturity and repricing relationships between interest-earning assets and interest-bearing liabilities at specific points in time. On a limited basis, the Company uses hedges such as swaps, rate floors, floor spreads, and futures contracts to manage interest rate risk on certain loans, trading securities, and trust preferred securities. See further information in Note 11 “Derivatives and Hedging Activities” in the Notes to the Consolidated Financial Statements.

Overall, the Company manages interest rate risk by positioning the balance sheet to maximize net interest income while maintaining an acceptable level of interest rate and credit risk, remaining mindful of the relationship among profitability, liquidity, interest rate risk, and credit risk.

Net Interest Income Modeling

The Company’s primary interest rate risk tool, the Net Interest Income Simulation Analysis, measures interest rate risk and the effect of interest rate changes on net interest income and net interest margin. This analysis incorporates all of the Company’s assets and liabilities together with assumptions that reflect the current interest rate environment. Through these simulations, management estimates the impact on net interest income of a 200-basis-point upward or a 300-basis-point downward gradual change (e.g. ramp) and immediate change (e.g. shock) of market interest rates over a two year period. In ramp scenarios, rates change gradually for a one-year period and remain constant in year two. In shock scenarios, rates change immediately and the change is sustained for the remainder of the two-year scenario horizon. Assumptions are made to project rates for new loans and deposits based on historical analysis, management outlook and repricing strategies. Asset prepayments and other market risks are developed from industry estimates of prepayment speeds and other market changes. The results of these simulations can be significantly influenced by assumptions utilized and management evaluates the sensitivity of the simulation results on a regular basis.

Table 14 shows the net interest income increase or decrease over the next two years as of March 31, 2024 and 2023 based on hypothetical changes in interest rates and a constant sized balance sheet with runoff being replaced.

The Company is positioned relatively neutral to changes in interest rates in the next year. Net interest income is predicted to decrease in all upward rate ramp scenarios and increase in all upward rate shock scenarios. In down rate scenarios, net interest income is predicted to increase in rate ramp scenarios and decrease in rate shock scenarios. In year two, net interest income is predicted to rise in all increasing rate scenarios and decrease in falling rate scenarios. The Company’s ability to price deposits consistent with its historical approach is a key assumption in these scenarios.

Trading Account

The Company carries securities in a trading account that is maintained according to Board-approved policy and procedures. The policy limits the amount and type of securities that can be carried in the trading account, requires compliance with any limits under applicable law and regulations, and mandates the use of a value-at-risk methodology to manage price volatility risks within financial parameters. The risk associated with the carrying of trading securities is offset by utilizing financial instruments including exchange-traded financial futures as well as short sales of U.S. Treasury and Corporate securities. The trading securities and related hedging instruments are marked-to-market daily. The trading account had a balance of $40.2 million as of March 31, 2024, $18.1 million as of December 31, 2023, and $19.8 million as of March 31, 2023. Securities sold not yet purchased (i.e., short positions) totaled $11.7 million at March 31, 2024, $8.0 million as of December 31, 2023, and $1.8 million at March 31, 2023 and are classified within the Other liabilities line of the Company’s Consolidated Balance Sheets.

75

The Company is subject to market risk primarily through the effect of changes in interest rates of its assets held for purposes other than trading. The discussion in Table 14 above of interest rate risk, however, combines instruments held for trading and instruments held for purposes other than trading, because the instruments held for trading represent such a small portion of the Company’s portfolio that the interest rate risk associated with them is immaterial.

Other Market Risk

The Company has minimal foreign currency risk as a result of foreign exchange contracts. See Note 10 “Commitments, Contingencies and Guarantees” in the notes to the Consolidated Financial Statements.

Credit Risk Management

Credit risk represents the risk that a customer or counterparty may not perform in accordance with contractual terms. The Company utilizes a centralized credit administration function, which provides information on the Bank’s risk levels, delinquencies, an internal ranking system and overall credit exposure. Loan requests are centrally reviewed to ensure the consistent application of the loan policy and standards. In addition, the Company has an internal loan review staff that operates independently of the Bank. This review team performs periodic examinations of the Bank’s loans for credit quality, documentation and loan administration. The respective regulatory authorities governing the Bank also review loan portfolios.

A primary indicator of credit quality and risk management is the level of nonperforming loans. Nonperforming loans include both nonaccrual loans and restructured loans on nonaccrual. The Company’s nonperforming loans increased $2.3 million to $17.8 million at March 31, 2024, compared to March 31, 2023, and increased $4.5 million, compared to December 31, 2023.

The Company had $2.5 million and $1.7 million of other real estate owned as of March 31, 2024 and December 31, 2023, respectively. Loans past due more than 90 days and still accruing interest totaled $3.1 million as of March 31, 2024, compared to $1.7 million at March 31, 2023 and $3.1 million as of December 31, 2023.

A loan is generally placed on nonaccrual status when payments are past due 90 days or more and/or when management has considerable doubt about the borrower’s ability to repay on the terms originally contracted. The accrual of interest is discontinued and recorded thereafter only when received in cash.

Certain loans are restructured to provide a reduction or deferral of interest or principal due to deterioration in the financial condition of the respective borrowers. The Company had $517 thousand of restructured loans at March 31, 2024, $6.0 million at March 31, 2023, and $548 thousand at December 31, 2023.

Liquidity Risk

Liquidity represents the Company’s ability to meet financial commitments through the maturity and sale of existing assets or availability of additional funds. The Company believes that the most important factor in the preservation of liquidity is maintaining public confidence that facilitates the retention and growth of a large, stable supply of core deposits and wholesale funds. Ultimately, the Company believes public confidence is generated through profitable operations, sound credit quality and a strong capital position. The primary source of liquidity for the Company is regularly scheduled payments on and maturity of assets, which include $6.5 billion of high-quality securities available for sale as of March 31, 2024. The liquidity of the Company and the Bank is also enhanced by its activity in the federal funds market and by its core deposits. Additionally, management believes it can raise debt or equity capital in the future, should the need arise.

Another factor affecting liquidity is the amount of deposits and customer repurchase agreements that have pledging requirements. All customer repurchase agreements require collateral in the form of a security. The U.S. Government, other public entities, and certain trust depositors require the Company to pledge securities if their deposit balances are greater than the FDIC-insured deposit limitations. These pledging requirements affect liquidity risk in that the related security cannot otherwise be disposed of due to the pledging restriction. There were $9.4 billion and $10.1 billion of securities pledged to secure U.S. Government deposits, other public deposits, certain trust deposits, derivative transactions, and repurchase agreements at March 31, 2024 and December 31, 2023, respectively.

The Company also has other commercial commitments that may impact liquidity. These commitments include unused commitments to extend credit, standby letters of credit and financial guarantees, and commercial letters of credit. The total amount of these commercial commitments at March 31, 2024 was $18.4 billion. Since many of these commitments expire without being drawn upon, the total amount of these commercial commitments does not necessarily represent the future cash requirements of the Company.

77

The Company’s cash requirements consist primarily of dividends to shareholders, debt service, operating expenses, and treasury stock purchases. Management fees and dividends received from bank and non-bank subsidiaries traditionally have been sufficient to satisfy these requirements and are expected to be sufficient in the future. The Bank is subject to various rules regarding payment of dividends to the Company. For the most part, the Bank can pay dividends at least equal to its current year’s earnings without seeking prior regulatory approval. The Company also uses cash to inject capital into its bank and non-bank subsidiaries to maintain adequate capital as well as fund strategic initiatives.

In September 2022, the Company issued $110.0 million in aggregate subordinated notes due in September 2032. The Company received $107.9 million, after deducting underwriting discounts and commissions and offering expenses, and used the proceeds from the offering for general corporate purposes, including, among other uses, contributing Tier 1 capital into the Bank. The subordinated notes were issued with a fixed-to-fixed rate of 6.25% and an effective rate of 6.64%, due to issuance costs, with an interest rate reset date of September 2027.

In September 2020, the Company issued $200.0 million in aggregate subordinated notes due in September 2030. The Company received $197.7 million, after deducting underwriting discounts and commissions and offering expenses, and used the proceeds from the offering for general corporate purposes, including, among other uses, contributing Tier 1 capital into the Bank. The subordinated notes were issued with a fixed-to-fixed rate of 3.70% and an effective rate of 3.93%, due to issuance costs, with an interest rate reset date of September 2025.

To enhance general working capital needs, the Company has a revolving line of credit with Wells Fargo Bank, N.A., which allows the Company to borrow up to $30.0 million for general working capital purposes. The interest rate applied to borrowed balances will be at the Company’s option, either 1.40% above SOFR or 1.75% below the prime rate on the date of an advance. The Company pays a 0.4% unused commitment fee for unused portions of the line of credit. The Company had no advances outstanding as of March 31, 2024.

The Company is a member bank of the FHLB. The Company owns $55.2 million of FHLB stock and has access to additional liquidity and funding sources through FHLB advances. The Company’s borrowing capacity is dependent upon the amount of collateral the Company places at the FHLB. The Company had a $1.0 billion short-term advance outstanding at FHLB of Des Moines as of March 31, 2024. Additionally, in the first quarter of 2024, the FHLB of Des Moines issued a letter of credit for $150.0 million on behalf of the Company to secure deposits. This letter of credit will expire in July 2024. The Company’s remaining borrowing capacity with the FHLB was $952.7 million as of March 31, 2024.

The Company had an $800.0 million short-term borrowing outstanding with the Federal Reserve Bank's BTFP as of March 31, 2024 at an interest rate of 4.76%. As of March 31, 2024, the Company’s remaining borrowing capacity with the BTFP was $30.0 million and its remaining borrowing capacity at the Federal Reserve Discount Window was $11.0 billion.

In addition to borrowing capacity with the FHLB and at the Federal Reserve Discount Window as described above, the Company had additional liquidity of $9.5 billion available via cash, unpledged bond collateral, the federal funds market, and the IntraFi Cash Service program as of March 31, 2024.

Operational Risk

Operational risk generally refers to the risk of loss resulting from the Company’s operations, including those operations performed for the Company by third parties. This would include but is not limited to the risk of fraud by employees or persons outside the Company, the execution of unauthorized transactions by employees or others, errors relating to transaction processing, breaches of the internal control system and compliance requirements, and unplanned interruptions in service. This risk of loss also includes the potential legal or regulatory actions that could arise as a result of an operational deficiency, or as a result of noncompliance with applicable regulatory standards. The Company must comply with a number of legal and regulatory requirements.

The Company operates in many markets and relies on the ability of its employees and systems to properly process a high number of transactions. In the event of a breakdown in internal control systems, improper operation

78

of systems or improper employee actions, the Company could suffer financial loss, face regulatory action and suffer damage to its reputation. In order to address this risk, management maintains a system of internal controls with the objective of providing proper transaction authorization and execution, safeguarding of assets from misuse or theft, and ensuring the reliability of financial and other data.

The Company maintains systems of internal controls that provide management with timely and accurate information about the Company’s operations. These systems have been designed to manage operational risk at appropriate levels given the Company’s financial strength, the environment in which it operates, and considering factors such as competition and regulation. The Company has also established procedures that are designed to ensure that policies relating to conduct, ethics, and business practices are followed on a uniform basis. In certain cases, the Company has experienced losses from operational risk. Such losses have included the effects of operational errors that the Company has discovered and included as expense in the statement of income. While there can be no assurance that the Company will not suffer such losses in the future, management continually monitors and works to improve its internal controls, systems, and corporate-wide processes and procedures.

ITEM 4. CONTROLS AND PROCEDURES

The Sarbanes-Oxley Act of 2002, as amended, requires the Chief Executive Officer and the Chief Financial Officer to make certain certifications under this Form 10-Q with respect to the Company’s disclosure controls and procedures and internal control over financial reporting. The Company has a Code of Ethics that expresses the values that drive employee behavior and maintains the Company’s commitment to the highest standards of ethics.

Disclosure Controls and Procedures

The Company’s management, with the participation of the Company's Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the Company's “disclosure controls and procedures” (as such term is defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended (the Exchange Act)) as of the end of the period covered by this Form 10-Q. Based on such evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Form 10-Q, the Company’s disclosure controls and procedures were effective for ensuring that the Company’s SEC filings are recorded, processed, summarized, and reported within the time period required and that information required to be disclosed by the Company is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures.

Internal Control Over Financial Reporting

There has been no change in the Company’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the three-month period ended March 31, 2024 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

79

PART II – OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the normal course of business, the Company and its subsidiaries are named defendants in various legal proceedings. In the opinion of management, after consultation with legal counsel, none of these lawsuits are expected to have a materially adverse effect on the financial position, results of operations, or cash flows of the Company.

ITEM 1A. RISK FACTORS

On April 29, 2024, the Company announced that it had entered into a definitive merger agreement with HTLF under which the Company will acquire HTLF in an all-stock transaction (the Merger). The following represents a material change in the Company's risk factors from those disclosed in Part I, Item 1A of the Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

The dilution caused by the issuance of shares of our common stock in connection with the Merger may adversely affect the market price of our common stock.

The dilution caused by the issuance of the new shares of our common stock to HTLF stockholders in connection with the payment of the Merger Consideration may result in fluctuations in the market price of our common stock, including a stock price decrease.

We may not be able to successfully integrate HTLF or to realize the anticipated benefits of the acquisition.

Upon consummation of the transactions contemplated by the merger agreement, we will begin the process of integrating HTLF. A successful integration of its business with ours will depend substantially on our ability to consolidate operations, corporate cultures, systems and procedures and to eliminate redundancies and costs. We may not be able to combine our business with the business of HTLF without encountering difficulties that could adversely affect the ability to maintain relationships with existing clients, customers, depositors and employees, such as:

•the loss of key employees;

•the disruption of operations and business;

•inability to maintain and increase competitive presence;

•loan and deposit attrition, customer loss and revenue loss;

•possible inconsistencies in standards, control procedures and policies;

•additional costs or unexpected problems with operations, personnel, technology and credit;

•inconsistencies in standards, controls, procedures and policies; and/or

•problems with the assimilation of new operations, systems, sites or personnel, which could divert resources from regular banking operations.

Any disruption to the businesses could cause customers to remove their accounts and move their business to a competing financial institution. Integration efforts between the two companies may also divert management attention and resources. Additionally, general market and economic conditions or governmental actions affecting the financial industry generally may inhibit our successful integration of HTLF.

Further, we expect to enter into the merger agreement to acquire HTLF with the expectation that the acquisition will result in various benefits including, among other things, benefits relating to enhanced revenues, a strengthened market position for the combined company, cross selling opportunities, technological efficiencies, cost savings and operating efficiencies. Achieving the anticipated benefits of the transactions contemplated by the merger agreement is subject to a number of uncertainties, including whether we integrate HTLF in an efficient, effective and timely manner, and general competitive factors in the marketplace. Failure to achieve these anticipated benefits on

80

the anticipated timeframe, or at all, could result in a reduction in the price of our common stock as well as in increased costs, decreases in the amount of expected revenues and diversion of management’s time and energy and could materially and adversely affect our business, financial condition and operating results. Additionally, upon consummation of the transactions contemplated by the merger agreement, we will make fair value estimates of certain assets and liabilities in recording the acquisition. Actual values of these assets and liabilities could differ from our estimates, which could result in our not achieving the anticipated benefits of the acquisition. Finally, any cost savings that are realized may be offset by losses in revenues or other charges to earnings.

We and HTLF have, and the combined company following the Merger will, incur significant transaction and Merger-related costs in connection with the transactions contemplated by the merger agreement.

We and HTLF have incurred and expect to incur significant non-recurring costs associated with combining the operations of HTLF with our operations. These costs include legal, financial advisory, accounting, consulting and other advisory fees, severance/employment-related costs, public company filing fees and other regulatory fees, printing costs and other related costs. We have begun collecting information in order to formulate detailed integration plans to deliver anticipated cost savings. Additional unanticipated costs may be incurred in the integration of our business with the business of HTLF, and there are many factors beyond our or HTLF’s control that could affect the total amount or timing of integration costs. Although we expect that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, may offset incremental transaction and Merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

Whether or not the Merger is consummated, we, HTLF and the combined company will incur substantial expenses in pursuing the Merger and may adversely impact our and the combined company’s earnings. Completion of the transactions contemplated by the merger agreement will be conditioned upon customary closing conditions, including the receipt of required governmental authorizations, consents, orders and approvals, including approval by certain federal banking regulators. We and HTLF intend to pursue all required approvals in accordance with the merger agreement. However, there can be no assurance that such approvals will be obtained without additional cost, on the anticipated timeframe, or at all.

Regulatory approvals for the Merger may not be received, may take longer than expected or may impose conditions that are not currently anticipated or that could have an adverse effect on the combined company following the Merger.

Before the proposed Merger and the Bank Merger, may be completed, various approvals, consents and non-objections must be obtained from regulatory authorities. In determining whether to grant these approvals, regulatory authorities consider a variety of factors, including the regulatory standing of each party. These approvals could be delayed or not obtained at all, including due to any or all of the following: an adverse development in any party’s regulatory standing or any other factors considered by regulators in granting such approvals, governmental, political or community group inquiries, investigations or opposition; changes in legislation or the political environment, including as a result of changes of the U.S. executive administration, or Congressional leadership and regulatory agency leadership.

Even if the approvals are granted, they may impose terms and conditions, limitations, obligations or costs, or place restrictions on the conduct of the combined company’s business or require changes to the terms of the transactions contemplated by the merger agreement. There can be no assurance that regulators will not impose any such conditions, limitations, obligations or restrictions or that such conditions, limitations, obligations or restrictions will not have the effect of delaying the completion of any of the transactions contemplated by the merger agreement, imposing additional material costs on or materially limiting the revenues of the combined company following the Merger or will otherwise reduce the anticipated benefits of the Merger. In addition, there can be no assurance that any such conditions, limitations, obligations or restrictions will not result in the delay or abandonment of the Merger. Additionally, the completion of the Merger is conditioned on the absence of certain orders, injunctions or decrees by any governmental entity of competent jurisdiction that would prohibit or make illegal the completion of the transactions contemplated by the merger agreement.

81

Despite the parties’ expected commitment to use their reasonable best efforts to respond to any request for information and resolve any objection that may be asserted by any governmental entity with respect to the merger agreement, neither party is required under the terms of the merger agreement to take any action, commit to take any action, or agree to any condition or restriction in connection with obtaining these approvals, that would reasonably be expected to have a material adverse effect on the combined company and its subsidiaries, taken as a whole, after giving effect to the proposed Merger (measured on a scale relative to HTLF and its subsidiaries, taken as a whole).

The merger agreement may be terminated in accordance with its terms and the Merger may not be completed. Such failure to complete the transactions contemplated by the merger agreement could cause our results to be adversely affected, our stock price to decline or have a material and adverse effect on our stock price and results of operations.

If the transactions contemplated by the merger agreement, including the Merger, are not completed for any reason, including as a result of our shareholders failing to approve the issuance of the shares of our common stock constituting the Merger Consideration (the “Share Issuance”) or the amendment to our restated articles of incorporation to increase of the number of authorized shares of our common stock (the “Articles Amendment”) or HTLF stockholders failing to approve the merger agreement, there may be various adverse consequences and we and/or HTLF may experience negative reactions from the financial markets and from our respective customers and employees. Moreover, our stock price may decline because costs related to such transactions, such as legal, accounting and financial advisory fees, must be paid even if such transactions, including the Merger, are not completed. Moreover, we may be required to pay a termination fee of $70 million to HTLF upon a termination of the merger agreement in certain circumstances. In addition, if the transactions contemplated by the merger agreement are not completed, whether because of our failure to receive required regulatory approvals in a timely fashion or because one of the parties has breached its obligations in a way that permits HTLF to terminate the merger agreement, or for any other reason, our stock price may decline to the extent that the current market price reflects a market assumption that the Merger will be completed.

The market price for our common stock following the closing of the transactions contemplated by the merger agreement may be affected by factors different from those that historically have affected or currently affect our common stock and HTLF common stock.

Subject to the terms and conditions of the merger agreement, upon completion of the Merger, holders of shares of HTLF common stock will receive shares of our common stock as Merger Consideration. The combined company’s business and financial position will differ from the business and financial position of the Company and HTLF before the completion of the Merger and, accordingly, the results of operations of the combined company will be affected by some factors that are different from those currently affecting our results of operations and those currently affecting the results of operations of HTLF. Accordingly, the market price and performance of our common stock is likely to be different from the performance of our common stock in the absence of the Merger. In addition, general fluctuations in stock markets could have a material adverse effect on the market for, or liquidity of, our common stock, regardless of our actual operating performance.

Upon completion of the transactions contemplated by the merger agreement, we will be subject to the risks related to HTLF’s business, including its commercial real estate loans.

Upon completion of the transactions contemplated by the merger agreement, we will be subject to risks related to HTLF’s business and take on its loans, investments and other obligations. This will increase our credit risk and, if such obligations are not repaid or losses are incurred on such obligations, there could be material and adverse effects on our business. Additionally, where our businesses overlap, any risks we face may be increased due to the transactions contemplated by the merger agreement. For example, HTLF’s loan portfolio has a large concentration of commercial real estate loans, which we will add to our existing portfolio. This may exacerbate the risks we already undertake with our own portfolio comprised meaningfully of commercial real estate loans, as described in our 2023 10-K under “Item 1A. Risk Factors—A meaningful part of the Company’s loan portfolio is secured by real estate and, as a result, could be negatively impacted by deteriorating or volatile real estate markets, the economic environment or associated environmental liabilities,” and may result in new ones.

For example, HTLF’s loan portfolio has a large concentration of commercial real estate loans, which involve additional risks because the value of real estate can fluctuate significantly in a short period of time as a result of

82

market conditions in any of the geographic bank markets in which such real estate is located, as well as because funds are advanced based on estimates of costs and the estimated value of the completed project and therefore have a greater risk of default in a weaker economy. Construction projects require prudent underwriting including determination of a borrower’s ability to complete the project, while staying within budget and on time in accordance with construction plans. Economic events, supply chain issues, labor market disruptions, and other factors outside the control of HTLF and our control, or that of the borrowers, could negatively impact the future cash flow and market values of affected properties.

As a result of the transactions contemplated by the merger agreement and our acquisition of HTLF, we will record goodwill in connection with such acquisition, and if it becomes impaired, our earnings could be significantly impacted.

Under current accounting methods, goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis and more frequently if an event occurs or circumstances change that reduce the fair value of a reporting unit below its carrying amount. In connection with our acquisition of HTLF, we will record goodwill in the fair value amount of such acquisition. Although we do not anticipate impairment charges, if we conclude that some portion of such goodwill is impaired, a non-cash charge for the amount of such impairment would be recorded against earnings.

Additionally, HTLF records a significant amount of goodwill. At December 31, 2023, HTLF had goodwill of $576.0 million, representing approximately 30% of its stockholders’ equity. Upon the Merger, we will take on HTLF’s goodwill, and if all or some portion of that $576.0 million is impaired following the acquisition, we would be required to take a non-cash charge for such amount against our earnings. A goodwill impairment charge could be caused by a decline in our stock price or the occurrence of a triggering event that compounds negative financial results. Further, because a large portion of HTLF’s portfolio is secured by commercial real estate loans, if such portfolio were to be seen as less valuable in a deteriorating real estate market, we may be required to record an impairment on our HTLF acquisition. Therefore, following the transactions contemplated by the merger agreement, including the Merger, and our recording of goodwill in connection therewith, if such goodwill becomes impaired, our earnings could be significantly and adversely affected.

The future results of the combined company following the Merger may suffer if the combined company does not effectively manage its expanded operations.

Following the Merger, the size of the business of the combined company will increase significantly beyond the current size of either our or HTLF’s business. The combined company’s future success will depend, in part, upon its ability to manage this expanded business, which may pose challenges for management, including challenges related to the management and monitoring of new operations and associated increased costs and complexity. The combined company may also face increased scrutiny from governmental authorities as a result of the significant increase in the size of its business.

In addition, HTLF’s bank subsidiary (“HTLF Bank”) is a Colorado state-chartered non-member bank subject to primary federal bank regulatory oversight by the Federal Deposit Insurance Corporation, while UMB Bank is, and the bank subsidiary of the combined company upon completion of the Bank Merger will be, a national bank subject to oversight by the Office of the Comptroller of the Currency (the “OCC”). The laws, regulations and regulatory guidance applicable to HTLF Bank and the bank subsidiary of the combined company will therefore differ in ways that may affect the operations of the combined company. Additionally, the internal policies of UMB Bank and HTLF Bank with regards to their investment portfolios may differ on factors such as hold limits per bond issuer, life of the bond, or credit risk appetite. As a result, there are assets on the balance sheet of HTLF Bank that the bank subsidiary of the combined company is not expected to hold, whether based on differences in regulatory oversight or internal policies, and we may dispose of such assets contemporaneous or subsequent to the closing of the Merger. The disposition of certain assets in a high-interest rate environment, such as we have in the past experienced, are currently experiencing and may experience again in the future, could result in a sale of assets at a market price that is different than the estimated book value of such assets and impact regulatory capital ratios at the time of the closing of the Merger. Further, we may replace such disposed assets with lower-yielding investments, any of which could impact our future earnings and return on equity.

83

There can be no assurances that the combined company will be successful or that it will realize the expected operating efficiencies, cost savings or other benefits currently anticipated from the Merger.

We and HTLF will be subject to business uncertainties and contractual restrictions while the Merger is pending.

Uncertainty about the effect of the Merger on employees and customers may have an adverse effect on us and HTLF. These uncertainties may impair our and HTLF’s ability to attract, retain and motivate key personnel until the Merger is completed, and could cause customers and others that deal with us or HTLF to seek to change existing business relationships with us or HTLF. In addition, subject to certain exceptions, we and HTLF expect to agree to operate our respective businesses in the ordinary course consistent with past practice in all material respects prior to closing, and we and HTLF expect to agree not to take certain actions, which could cause us or HTLF to be unable to pursue other beneficial opportunities that may arise prior to the completion of the Merger.

Litigation related to the Merger could prevent or delay completion of the Merger or otherwise negatively affect the business and operations of us and HTLF.

We and HTLF may incur costs in connection with the defense or settlement of any shareholder or stockholder lawsuits filed in connection with the Merger. Such litigation could have an adverse effect on our and HTLF’s financial condition and results of operations and could prevent or delay the completion of the Merger.

The Merger will not be completed unless important conditions are satisfied or waived, including approval of the merger agreement by HTLF stockholders and approval of the Share Issuance and the Articles Amendment by our shareholders.

Specified conditions set forth in the merger agreement must be satisfied or waived to complete the Merger. If the conditions are not satisfied or, subject to applicable law, waived, the Merger will not occur or will be delayed and each of HTLF and us may lose some or all of the intended benefits of the Merger.

These purchases do not count against the maximum value of shares remaining available for purchase under Repurchase Authorizations.

(2) Includes shares acquired under the Board of Directors approved Repurchase Authorization(s).

On July 25, 2023, the Company announced a plan to repurchase up to one million shares of common stock, which terminated on April 30, 2024. On April 30, 2024, the Company announced a plan to repurchase up to one

million shares of common stock, which will terminate on April 29, 2025. The Company has not made any repurchases other than through the Repurchase Authorizations, but did acquire shares pursuant to the Company's share-based incentive programs. The Company is not currently engaging in repurchases. In the future, it may determine to resume repurchases. All share purchases pursuant to the Repurchase Authorizations are intended to be within the scope of Rule 10b-18 promulgated under the Exchange Act. Rule 10b-18 provides a safe harbor for purchases in a given day if the Company satisfies the manner, timing and volume conditions of the rule when purchasing its own shares of common stock.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. These estimates and assumptions also impact reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A summary of the significant accounting policies to assist the reader in understanding the financial presentation is provided in the Notes to Consolidated Financial Statements in the Form 10-K.

Cash and cash equivalents

Cash and cash equivalents include Cash and due from banks and amounts due from the Federal Reserve Bank (FRB). Cash on hand, cash items in the process of collection, and amounts due from correspondent banks are included in Cash and due from banks. Amounts due from the FRB are interest-bearing for all periods presented and are included in the Interest-bearing due from banks line on the Company’s Consolidated Balance Sheets.

This table provides a summary of cash and cash equivalents as presented on the Consolidated Statements of Cash Flows as of March 31, 2024 and March 31, 2023 (in thousands):

	March 31,
	2024		2023
Due from the FRB	$	6,586,145	$	3,051,056
Cash and due from banks		356,963		472,248
Cash and cash equivalents at end of period	$	6,943,108	$	3,523,304

Also included in the Interest-bearing due from banks, but not considered cash and cash equivalents, are interest-bearing accounts held at other financial institutions, which totaled $87.0 million and $70.1 million at March 31, 2024 and March 31, 2023, respectively.

Per Share Data

Basic net income per share is computed based on the weighted average number of shares of common stock outstanding during each period. Diluted quarter-to-date net income per share includes the dilutive effect of 257,348 and 311,546 shares issuable upon the exercise of stock options and nonvested restricted stock units granted by the Company that were outstanding at March 31, 2024 and 2023, respectively.

Certain options and restricted stock units issued under employee benefit plans were excluded from the computation of diluted earnings per share because they were anti-dilutive. For the three months ended March 31, 2024, there were no outstanding stock options and restricted stock units excluded from the computation of diluted income per share. For the three months ended March 31, 2023, there were 166,578 outstanding stock options or restricted stock units excluded from the computation of diluted income per share because their inclusion would have been anti-dilutive.

Derivatives

The Company records all derivatives on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Currently, ten of the Company’s derivatives are designated in qualifying hedging relationships. The remainder of the Company’s derivatives are not designated in qualifying hedging relationships, as the derivatives are not used to manage risks within the Company’s assets or liabilities. All changes in fair value of the Company’s non-designated derivatives and fair value hedges are recognized directly in earnings. Changes in fair value of the Company’s cash flow hedges are recognized in accumulated other comprehensive income (AOCI) and are reclassified to earnings when the hedged transaction affects earnings.

Accounting Changes And Error Corrections [Abstract]

New Accounting Pronouncements

3. New Accounting Pronouncements

Troubled Debt Restructurings In March 2022, the FASB issued Accounting Standards Update (ASU) No. 2022-02, “Financial Instruments – Credit Losses: Troubled Debt Restructurings and Vintage Disclosures.” The ASU eliminated the accounting guidance for troubled debt restructurings (TDR) by creditors and enhances disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. The amendments also added requirements to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases, disclosed by credit-quality indicator and class of financing receivable. The amendments in this update were adopted prospectively on January 1, 2023. The adoption of the amendments had no impact on the Consolidated Financial Statements aside from additional and revised financial statement disclosures. See Note 3, "Loans and Allowance for Credit Losses" for related disclosures.

Equity-Method Investments In March 2023, the FASB issued ASU No. 2023-02, "Investments-Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method." The ASU allows 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. Previously, this method was only available for qualifying tax equity investments in low-income housing tax credit structures. The Company adopted the amended guidance on January 1, 2024, upon which the Company elected to continue the use of the practical expedient under ASC 323-740-35-4 to account for low-income housing tax credit and historic tax credit investments. Under the practical expedient, the cost of a tax equity investment is amortized in proportion to income tax credits only and is recorded on a net basis within income tax expense. The adoption of this amendment did not have any impact on the Consolidated Financial Statements aside from annual disclosures which will be included in the Company's Annual Report on Form 10-K.

Income Taxes In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The ASU is intended to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this update require additional disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this update are effective for fiscal years

beginning after December 15, 2024. Early adoption is permitted. The adoption of this accounting pronouncement will have no impact on the Consolidated Financial Statements aside from additional disclosures.

Loans and Allowance for Credit Losses

4. Loans and Allowance for Credit Losses

Loan Origination/Risk Management

The Company has certain lending policies and procedures in place that are designed to minimize the level of risk within the loan portfolio. Diversification of the loan portfolio manages the risk associated with fluctuations in economic conditions. Authority levels are established for the extension of credit to ensure consistency throughout the Company. It is necessary that policies, processes, and practices implemented to control the risks of individual credit transactions and portfolio segments are sound and adhered to. The Company maintains an independent loan review department that reviews and validates the risk assessment on a continual basis. Management regularly evaluates the results of the loan reviews. The loan review process complements and reinforces the risk identification and assessment decisions made by lenders and credit personnel, as well as the Company’s policies and procedures.

Commercial and industrial loans are underwritten after evaluating and understanding the borrower’s ability to operate profitably and prudently expand its business. Commercial loans are made based on the identified cash flows of the borrower and on the underlying collateral provided by the borrower. The cash flows of the borrower, 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. 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 from its customers.

Specialty lending loans include Asset-based loans, which are offered primarily in the form of revolving lines of credit to commercial borrowers that do not generally qualify for traditional bank financing. Asset-based loans are underwritten based primarily upon the value of the collateral pledged to secure the loan, rather than on the borrower’s general financial condition. The Company utilizes pre-loan due diligence techniques, monitoring disciplines, and loan management practices common within the asset-based lending industry to underwrite loans to these borrowers.

Commercial real estate loans are subject to underwriting standards and processes similar to commercial loans, in addition to those of real estate loans. These 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 largely dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. The Company requires that an appraisal of the collateral be made at origination and on an as-needed basis, in conformity with current market conditions and regulatory requirements. The underwriting standards address both owner and non-owner-occupied real estate. Also included in Commercial real estate are Construction loans that are underwritten using feasibility studies, independent appraisal reviews, sensitivity analysis or absorption and lease rates, and financial analysis of the developers and property owners. Construction loans are based upon estimates of costs and value associated with the complete project. 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, sales of developed property or an interim loan commitment from the Company 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 repayment being sensitive to interest rate changes, governmental regulation of real property, economic conditions, completion of the construction project, and the availability of long-term financing.

Consumer real estate loans, including residential real estate and home equity loans, are underwritten based on the borrower’s loan-to-value percentage, collection remedies, and overall credit history.

Consumer loans are underwritten based on the borrower’s repayment ability. The Company monitors delinquencies on all of its consumer loans and leases. The underwriting and review practices combined with the

relatively small loan amounts that are spread across many individual borrowers, minimizes risk. Consumer loans and leases that are 90 days past due or more are considered non-performing.

Credit cards include both commercial and consumer credit cards. Commercial credit cards are generally unsecured and are underwritten with criteria similar to commercial loans, including an analysis of the borrower’s cash flow, available business capital, and overall creditworthiness of the borrower. Consumer credit cards are underwritten based on the borrower’s repayment ability. The Company monitors delinquencies on all of its consumer credit cards and periodically reviews the distribution of credit scores relative to historical periods to monitor credit risk on its consumer credit card loans. During the first quarter of 2024, the Company purchased a co-branded credit card portfolio. The purchase included $109.4 million in credit card receivables.

Credit risk is a potential loss resulting from nonpayment of either the primary or secondary exposure. Credit risk is mitigated with formal risk management practices and a thorough initial credit-granting process including consistent underwriting standards and approval process. Control factors or techniques to minimize credit risk include knowing the client, understanding total exposure, analyzing the client and debtor’s financial capacity, and monitoring the client’s activities. Credit risk and portions of the portfolio risk are managed through concentration considerations, average risk ratings, and other aggregate characteristics.

Credit Quality Indicators

As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to the risk grading of specified classes of loans, net charge-offs, non-performing loans, and general economic conditions.

The Company utilizes a risk grading matrix to assign a rating to each of its commercial, commercial real estate, and construction real estate loans. Changes in credit risk are monitored on a continuous basis and changes in risk ratings are made when identified. The loan ratings are summarized into the following categories: Non-watch list, Watch, Special Mention, Substandard, and Doubtful. Any loan not classified in one of the categories described below is considered to be a Non-watch list loan. A description of the general characteristics of the loan rating categories is as follows:

•Watch – This rating represents credit exposure that presents higher than average risk and warrants greater than routine attention by Company personnel due to conditions affecting the borrower, the borrower’s industry, or the economic environment. These conditions have resulted in some degree of uncertainty that results in higher-than-average credit risk. These loans are considered pass-rated credits.

•Special Mention – This rating reflects 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 asset or the borrower’s credit position at some future date. The rating is not adversely classified and does not expose an institution to sufficient risk to warrant adverse classification.

•Substandard – This rating represents an asset inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. Loans in this category are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified as substandard.

•Doubtful – This rating represents an asset that has all the weaknesses inherent in an asset classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing facts, conditions and values, highly questionable and improbable. The possibility of loss is extremely high, but because of certain important and reasonably specific pending factors, which may work to the advantage of strengthening the asset, its classification as an estimated loss is deferred until its more exact status may be determined. Pending factors include proposed merger, acquisition, liquidation procedures, capital injection, or perfecting liens.

Commercial and industrial

A discussion of the credit quality indicators that impact each type of collateral securing Commercial and industrial loans is included below:

Equipment, accounts receivable, and inventory General commercial and industrial loans are secured by working capital assets and non-real estate assets. The general purpose of these loans is for financing capital expenditures and current operations for commercial and industrial entities. These assets are short-term in nature. In the case of accounts receivable and inventories, the repayment of debt is reliant upon converting assets into cash or through goods and services being sold and collected. Collateral-based risk is due to aged short-term assets, which can be indicative of underlying issues with the borrower and lead to the value of the collateral being overstated.

Agriculture Agricultural loans are secured by non-real estate agricultural assets. These include shorter-term assets such as equipment, crops, and livestock. The risks associated with loans to finance crops or livestock include the borrower’s ability to successfully raise and market the commodity. Adverse weather conditions and other natural perils can dramatically affect farmers’ or ranchers’ production and ability to service debt. Volatile commodity prices present another significant risk for agriculture borrowers. Market price volatility and production cost volatility can affect both revenues and expenses.

Overdrafts Commercial overdrafts are typically short-term and unsecured. Some commercial borrowers tie their overdraft obligation to their line of credit, so any draw on the line of credit will satisfy the overdraft.

Based on the factors noted above for each type of collateral, the Company assigns risk ratings to borrowers based on their most recently assessed financial position.

Specialty lending

A discussion of the credit quality indicators that impact each type of collateral securing Specialty loans is included below:

Asset-based lending General asset-based loans are secured by accounts receivable, inventory, equipment, and real estate. The purpose of these loans is for financing current operations for commercial customers. The repayment of debt is reliant upon collection of the accounts receivable within 30 to 90 days or converting assets into cash or through goods and services being sold and collected. The Company tracks each individual borrower credit risk based on their loan to collateral position. Any borrower position where the underlying value of collateral is below the fair value of the loan is considered out-of-margin and inherently higher risk.

The following table provides a summary of the amortized cost balance by risk rating for asset-based loans as of March 31, 2024 and December 31, 2023 (in thousands):

	Asset-based lending
Risk	March 31, 2024		December 31, 2023
In-margin	$	508,162	$	498,786
Out-of-margin		—		—
Total	$	508,162	$	498,786

Commercial real estate

A discussion of the credit quality indicators that impact each type of collateral securing Commercial real estate loans is included below:

Owner-occupied Owner-occupied loans are secured by commercial real estate. These loans are often longer tenured and susceptible to multiple economic cycles. The loans rely on the owner-occupied operations to service debt which cover a broad spectrum of industries. Real estate debt can carry a significant amount of leverage for a borrower to maintain.

Non-owner-occupied Non-owner-occupied loans are secured by commercial real estate. These loans are often longer tenured and susceptible to multiple economic cycles. The key element of risk in this type of lending is the cyclical nature of real estate markets. Although national conditions affect the overall real estate industry, the effect of national conditions on local markets is equally important. Factors such as unemployment rates, consumer demand, household formation, and the level of economic activity can vary widely from state to state and among metropolitan areas. In addition to geographic considerations, markets can be defined by property type. While all sectors are influenced by economic conditions, some sectors are more sensitive to certain economic factors than others.

Farmland Farmland loans are secured by real estate used for agricultural purposes such as crop and livestock production. Assets used as collateral are long-term assets that carry the ability to have longer amortizations and maturities. Longer terms carry the risk of added susceptibility to market conditions. The limited purpose of some Agriculture-related collateral affects credit risk because such collateral may have limited or no other uses to support values when loan repayment problems emerge.

5+ Multi-family 5+ multi-family loans are secured by a multi-family residential property. The primary risks associated with this type of collateral are largely driven by economic conditions. The national and local market conditions can change with unemployment rates or competing supply of multi-family housing. Tenants may not be able to afford their housing or have better options and this can result in increased vacancy. Rents may need to be lowered to fill apartment units. Increased vacancy and lower rental rates not only drive the borrower’s ability to repay debt but also contribute to how the collateral is valued.

1-4 Family construction 1-4 family construction loans are secured by 1-4 family residential real estate and are in the process of construction or improvements being made. The predominant risk inherent to this portfolio is the risk associated with a borrower’s ability to successfully complete a project on time and within budget. Market conditions also play an important role in understanding the risk profile. Risk from adverse changes in market conditions from the start of development to completion can result in deflated collateral values.

General construction General construction loans are secured by commercial real estate in process of construction or improvements being made and their repayment is dependent on the collateral’s completion. Construction lending presents unique risks not encountered in term financing of existing real estate. The predominant risk inherent to this portfolio is the risk associated with a borrower’s ability to successfully complete a project on time and within budget. Commercial properties under construction are susceptible to market and economic conditions. Demand from prospective customers may erode after construction begins because of a general economic slowdown or an increase in the supply of competing properties.

Based on the factors noted above for each type of collateral, the Company assigns risk ratings to borrowers based on their most recently assessed financial position.

Consumer real estate

A discussion of the credit quality indicators that impact each type of collateral securing Consumer real estate loans is included below:

HELOC HELOC loans are revolving lines of credit secured by 1-4 family residential property. The primary risk is the borrower’s inability to repay debt. Revolving notes are often associated with HELOCs that can be secured by real estate without a 1st lien priority. Collateral is susceptible to market volatility impacting home values or economic downturns.

First lien: 1-4 family First lien 1-4 family loans are secured by a first lien on 1-4 family residential property. These term loans carry longer maturities and amortizations. The longer tenure exposes the borrower to multiple economic cycles, coupled with longer amortizations that result in smaller principal reduction early in the life of the loan. Collateral is susceptible to market volatility impacting home values.

Junior lien: 1-4 family Junior lien 1-4 family loans are secured by a junior lien on 1-4 family residential property. The Company’s primary risk is the borrower’s inability to repay debt and not being in a first lien position. Collateral is susceptible to market volatility impacting home values or economic downturns.

A borrower is considered non-performing if the Company has ceased the recognition of interest and the loan is placed on non-accrual. Charge-offs and borrower performance are tracked on a loan origination vintage basis. Certain vintages, based on their maturation cycle, could be at higher risk due to collateral-based risk factors.

Consumer

A discussion of the credit quality indicators that impact each type of collateral securing Consumer loans is included below:

Revolving line Consumer Revolving lines of credit are secured by consumer assets other than real estate. The primary risk associated with this collateral is related to market volatility and the value of the underlying financial assets.

Auto Direct consumer auto loans are secured by new and used consumer vehicles. The primary risk with this collateral class is the rate at which the collateral depreciates.

Other This category includes Other consumer loans made to an individual. The primary risk for this category is for those loans where the loan is unsecured. This collateral type also includes other unsecured lending such as consumer overdrafts.

A borrower is considered non-performing if the Company has ceased the recognition of interest and the loan is placed on non-accrual. Charge-offs and borrower performance are tracked on a loan origination vintage basis. Certain vintages, based on their maturation cycle, could be at higher risk due to collateral-based risk factors.

Credit cards

A discussion of the credit quality indicators that impact Credit card loans is included below:

Consumer Consumer credit card loans are revolving loans made to individuals. The primary risk associated with this collateral class is credit card debt which is generally unsecured; therefore, repayment depends primarily on a borrower’s willingness and capacity to repay. The highly competitive environment for credit card lending provides consumers with ample opportunity to hold several credit cards from different issuers and to pay only minimum monthly payments on outstanding balances. In such an environment, borrowers may become over-extended and unable to repay, particularly in times of an economic downturn or a personal catastrophic event.

The consumer credit card portfolio is segmented by borrower payment activity. Transactors are defined as accounts that pay off their balance by the end of each statement cycle. Revolvers are defined as an account that carries a balance from one statement cycle to the next. These accounts incur monthly finance charges, and, sometimes, late fees. Revolvers are inherently higher risk and are tracked by credit score.

Commercial Commercial credit card loans are revolving loans made to small and commercial businesses. The primary risk associated with this collateral class is credit card debt which is generally unsecured; therefore, repayment depends primarily on a borrower’s willingness and capacity to repay. Borrowers may become over-extended and unable to repay, particularly in times of an economic downturn or a catastrophic event.

The commercial credit card portfolio is segmented by current and past due payment status. A borrower is past due after 30 days. In general, commercial credit card customers do not have incentive to hold a balance resulting in paying interest on credit card debt as commercial customers will typically have other debt obligations with lower interest rates in which they can utilize for capital.

Leases and other

A discussion of the credit quality indicators that impact each type of collateral securing Leases and other loans is included below:

Leases Leases are either loans to individuals for household, family and other personal expenditures or are loans related to all other direct financing and leveraged leases on property for leasing to lessees other than for household, family and other personal expenditure purposes. All leases are secured by the lease between the lessor and the lessee. These assignments grant the creditor a security interest in the rent stream from any lease, an important source of cash to pay the note in case of the borrower’s default.

Other Other loans are loans that are obligations of states and political subdivisions in the U.S., loans to non-depository financial institutions, loans for purchasing or carrying securities, or all other non-consumer loans. Risk associated with other loans is tied to the underlying collateral by each type of loan. Collateral is generally equipment, accounts receivable, inventory, 1-4 family residential construction and susceptible to the same risks mentioned with those collateral types previously. Other risks consist of collateral that is secured by the stock of a non-depository financial institution, which can be unlisted stock with a limited market for the stock, or volatility of asset values driven by market performance.

Based on the factors noted above for each type of collateral, the Company assigns risk ratings to borrowers based on their most recently assessed financial position.

The following table provides a summary of the amortized cost balance by collateral type and risk rating as of March 31, 2024 and December 31, 2023 (in thousands):

Allowance for Credit Losses

The allowance for credit losses (ACL) is a valuation account that is deducted from loans’ and held-to-maturity (HTM) securities’ amortized cost bases to present the net amount expected to be collected on the instrument. Loans and HTM securities are charged off against the ACL when management believes the balance has become uncollectible. Expected recoveries are included in the allowance and do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.

Management estimates the allowance balance using relevant available information, from internal and external sources, related to past events, current conditions, and reasonable and supportable economic forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses and is tracked over an economic cycle to capture a ‘through the cycle’ loss history. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in portfolio industry-based segmentation, risk rating and credit score changes, average prepayment rates, changes in environmental conditions, or other relevant factors. For economic forecasts, the Company uses the Moody’s baseline scenario. The Company has developed a dynamic reasonable and supportable forecast period that ranges from one to three years and changes based on economic conditions. Due to current economic conditions, the Company’s reasonable and supportable forecast period is one year. After the reasonable and supportable forecast period, the Company reverts to historical losses. The reversion method applied to each portfolio can either be cliff or straight-line over four quarters.

The ACL is measured on a collective (pool) basis when similar risk characteristics exists. The ACL also incorporates qualitative factors which represent adjustments to historical credit loss experience for items such as concentrations of credit and results of internal loan review. The Company has identified the following portfolio

segments and measures the allowance for credit losses using the following methods. The Company’s portfolio segmentation consists of Commercial and industrial, Specialty lending, Commercial real estate, Consumer real estate, Consumer, Credit cards, Leases and other, and Held-to-maturity securities. Multiple modeling techniques are used to measure credit losses based on the portfolio.

The ACL for Commercial and industrial and Leases and other segments are measured using a probability of default and loss given default method. Primary risk drivers within the segment are risk ratings of the individual loans along with changes of macro-economic variables. The economic variables utilized are typically comprised of leading and lagging indicators. The ACL for Commercial and industrial loans is calculated by modeling probability of default (PD) over future periods multiplied by historical loss given default rates (LGD) multiplied by contractual exposure at default minus any estimated prepayments and charge offs.

Collateral positions for Specialty lending loans are continuously monitored by the Company and the borrower is required to continually adjust the amount of collateral securing the loan. Credit losses are measured for any position where the amortized cost basis is greater than the fair value of the collateral. The ACL for specialty lending loans is calculated by using a bottom-up approach comparing collateral values to outstanding balances.

The ACL for the Commercial real estate segment is measured using a PD and LGD method. Primary risk characteristics within the segment are risk ratings of the individual loans, along with changes of macro-economic variables, such as interest rates, CRE price index, median household income, construction activity, farm income, and vacancy rates. The ACL for Commercial real estate loans is calculated by modeling PD over future periods based on peer bank data. The PD loss rate is then multiplied by historical LGD multiplied by contractual exposure at default minus any estimated prepayments and charge offs.

The ACL for the Consumer real estate and Consumer segments are measured using an origination vintage loss rate method applied to the loans’ amortized cost balance. The primary risk driver within the segments is year of origination along with changes of macro-economic variables such as unemployment and the home price index.

The Credit card segment contains both consumer and commercial credit cards. The ACL for Consumer credit cards is measured using a PD and LGD method for Revolvers and average historical loss rates across a defined lookback period for Transactors. The PD and LGD method used for Revolvers is similar in nature to the method used in the Commercial and industrial and Commercial real estate segments. Primary risk drivers within the segment are credit ratings of the individual card holders along with changes of macro-economic variables such as unemployment and retail sales. The ACL for Commercial credit cards is measured using roll-rate loss rate method based on days past due.

The ACL for the State and political HTM securities segment is measured using a loss rate method based on historical bond rating transitions. Primary risk drivers within the segment are bond ratings in the portfolio along with changes of macro-economic conditions. There is no ACL for the U.S. Agency and GSE mortgage-backed HTM securities portfolios as they are considered to be agency-backed securities with no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. For further discussion on these securities, including the aging and amortized cost balance of HTM securities, see Note 5, “Securities.”

See the credit quality indicators presented previously for a summary of current risk in the Company’s portfolio. Changes in economic forecasts will affect all portfolio segments, updated financial records from borrowers will affect portfolio segments by risk rating, updated credit scores will affect consumer credit cards, payment performance will affect consumer and commercial credit card portfolio segments, and updated bond credit ratings will affect held-to-maturity securities. The Company actively monitors all credit quality indicators for risk changes that will influence the current estimate.

Expected credit losses are estimated over the contractual term of the loans, adjusted for prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a concessionary loan term has been granted to a borrower experiencing financial difficulty or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancelable by the Company.

Credit card receivables do not have stated maturities. In determining the estimated life of a credit card receivable, management first estimates the future cash flows expected to be received and then applies those expected future cash flows to the credit card balance. Expected credit losses for credit cards are determined by estimating the amount and timing of principal payments expected to be received as payment for the balance outstanding as of the reporting period until the expected payments have been fully allocated. The ACL is recorded for the excess of the balance outstanding as of the reporting period over the expected principal payments.

Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually include loans on nonaccrual, loans that include modifications deemed concessionary made to borrowers experiencing financial difficulty, or any loans specifically identified, and are excluded from the collective evaluation. When it is determined that payment of interest or recovery of all principal is questionable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for undiscounted selling costs as appropriate. All loans are classified as collateral dependent if placed on non-accrual or include modifications made to borrowers experiencing financial difficulty.

Modifications made to Borrowers Experiencing Financial Difficulty

In the normal course of business, the Company may execute loan modifications with borrowers. These modifications are analyzed to determine whether the modification is considered concessionary, long term and made to a borrower experiencing financial difficulty. The Company’s modifications generally include interest rate adjustments, principal reductions, and amortization and maturity date extensions. These modifications allow the borrower short-term cash relief to allow them to improve their financial condition. If a loan modification is determined to be made to a borrower experiencing financial difficulty, the loan is considered collateral dependent and evaluated as part of the ACL as described above in the Allowance for Credit Losses section of this note.

For the three months ended March 31, 2024 and March 31, 2023, the Company did not modify any loans made to borrowers experiencing financial difficulty.

The Company had no commitments to lend to borrowers experiencing financial difficulty for which the Company has modified an existing loan as of March 31, 2024 and 2023. The Company monitors loan payments on an on-going basis to determine if a loan is considered to have a payment default. Determination of payment default involves analyzing the economic conditions that exist for each customer and their ability to generate positive cash flows during the loan term. For the three-month period ended March 31, 2024 and March 31, 2023, the Company had no loan modifications made to borrowers experiencing financial difficulty for which there was a payment default within the 12 months following the modification date.

Securities may be disposed of before contractual maturities due to sales by the Company or because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

For the three months ended March 31, 2024, there were $19.2 million in proceeds from the sales of securities available for sale. For the three months ended March 31, 2023 there were $68 thousand in proceeds from the sales of

securities available for sale. Securities transactions resulted in gross realized gains of $139 thousand and no gross realized losses for the three months ended March 31, 2024. There were $2 thousand in gross realized losses and no gross realized gains for the three months ended March 31, 2023.

There were $9.4 billion and $10.1 billion of securities pledged to secure U.S. Government deposits, other public deposits, certain trust deposits, derivative transactions, and repurchase agreements at March 31, 2024 and December 31, 2023, respectively.

Accrued interest on securities available for sale totaled $30.3 million and $31.6 million as of March 31, 2024 and December 31, 2023, respectively, and is included in the Accrued income line on the Company’s Consolidated Balance Sheets. The total amount of accrued interest is excluded from the amortized cost of available-for-sale securities presented above. Further, the Company has elected not to measure an ACL for accrued interest receivable.

The following table shows the Company’s available-for-sale investments’ gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at March 31, 2024 and December 31, 2023 (in thousands):

The unrealized losses in the Company’s investments were caused by changes in interest rates, and not from a decline in credit of the underlying issuers. The U.S. Treasury, U.S. Agency, and GSE mortgage-backed securities are all considered to be agency-backed securities with no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. The changes in fair value in the agency-backed portfolios are solely driven by change in interest rates caused by changing economic conditions. The Company has no knowledge of any underlying credit issues and the cash flows underlying the debt securities have not changed and are not expected to be impacted by changes in interest rates.

For the State and political subdivision portfolio, the majority of the Company’s holdings are in general obligation bonds, which have a very low historical default rate due to issuers generally having unlimited taxing authority to service the debt. For the State and political, Corporates, and Collateralized loan obligations portfolios, the Company has a robust process for monitoring credit risk, including both pre-purchase and ongoing post-purchase credit reviews and analysis. The Company monitors credit ratings of all bond issuers in these segments and reviews available financial data, including market and sector trends.

During the three months ended March 31, 2023, the Company recorded a $4.8 million impairment on one Corporate available-for-sale security.

As of March 31, 2024 and December 31, 2023, there was no ACL related to the Company’s available-for-sale securities as the decline in fair value did not result from credit issues.

Total securities held to maturity	$	5,626,437	$	5,025,138

Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

There were no sales of securities held to maturity during the three months ended March 31, 2024 or 2023.

During the year ended December 31, 2022, securities with an amortized cost of $4.1 billion and a fair value of $3.8 billion were transferred from the available-for-sale classification to the held-to-maturity classification as the Company has the positive intent and ability to hold these securities to maturity. The transfers of securities were made at fair value at the time of transfer. The unrealized holding gain or loss at the time of transfer is retained in AOCI and will be amortized over the remaining life of the securities, offsetting the related amortization of discount or premium on the transferred securities. No gains or losses were recognized at the time of the transfers. The amortized cost balance of securities held to maturity in the tables above includes a net unamortized unrealized loss of $198.4 million at March 31, 2024.

Accrued interest on securities held to maturity totaled $24.0 million and $27.2 million as March 31, 2024 and December 31, 2023, respectively, and is included in the Accrued income line on the Company’s Consolidated Balance Sheets. The total amount of accrued interest is excluded from the amortized cost of held-to-maturity securities presented above.

The unrealized losses in the Company’s held-to-maturity portfolio were caused by changes in the interest rate environment. The U.S. Agency and GSE mortgage-backed securities are considered to be agency-backed securities with no risk of loss as they are either explicitly or implicitly guaranteed by the U.S. government. Therefore, the Company’s expected lifetime loss for these portfolios is zero and there is no ACL recorded for these portfolios. The Company has no knowledge of any underlying credit issues and the cash flows underlying the debt securities have not changed and are not expected to be impacted by changes in interest rates.

For the State and political subdivision portfolio, the Company’s holdings are in general obligation bonds as well as private placement bonds, which have very low historical default rates due to issuers generally having unlimited taxing authority to service the debt. The Company has a robust process for monitoring credit risk, including both pre-purchase and ongoing post-purchase credit reviews and analysis. The Company monitors credit ratings of all bond issuers in these segments and reviews available financial data, including market and sector trends. The underlying bonds are evaluated for credit losses in conjunction with management’s estimate of the ACL based on credit rating.

Trust and securities processing – Trust and securities processing income consists of fees earned on personal and corporate trust accounts, custody of securities services, trust investments and wealth management services, and mutual fund and alternative asset servicing. The performance obligations related to this revenue include items such as performing full bond trustee service administration, investment advisory services, custody and record-keeping services, and fund administrative and accounting services. These fees are part of long-term contractual agreements and the performance obligations are satisfied upon completion of service and fees are generally a fixed flat monthly rate or based on a percentage of the account’s market value per the contract with the customer. These fees are primarily recorded within the Company’s Institutional and Personal Banking segments.

Trading and investment banking – Trading and investment banking income consists of income earned related to the Company’s trading securities portfolio, including futures hedging, dividends, bond underwriting, and other securities incomes. The vast majority of this revenue is recognized in accordance with ASC 320, Debt and Equity Securities, and is out of the scope of ASC 606. A portion of trading and investment banking represents fees earned for management fees, commissions, and underwriting of corporate bond issuances. The performance obligations related to these fees include reviewing the credit worthiness of the customer, ensuring appropriate regulatory approval and participating in due diligence. The fees are fixed per the bond prospectus and the performance obligations are satisfied upon registration approval of the bonds by the applicable regulatory agencies. Revenue is recognized at the point in time upon completion of service and when approval is granted by the regulators.

Service charges on deposits – Service charges on deposit accounts represent monthly analysis fees recognized for the services related to customer deposit accounts, including account maintenance and depository transactions processing fees. Commercial Banking and Institutional Banking depository accounts charge fees in accordance with the customer’s pricing schedule while Personal Banking account holders are generally charged a flat service fee per month. Deposit service charges for the healthcare accounts included in the Institutional Banking segment are priced according to either standard pricing schedules with individual account holders or according to service agreements between the Company and employer groups or third-party administrators. The Company satisfies the performance obligation related to providing depository accounts monthly as transactions are processed and deposit service charge revenue is recorded monthly. These fees are recognized within all Business Segments.

Insurance fees and commissions – Insurance fees and commissions includes all insurance-related fees earned, including commissions for individual life, variable life, group life, health, group health, fixed annuity, and variable annuity insurance contracts. The performance obligations related to these revenues primarily represent the placement of insurance policies with the insurance company partners.

Brokerage fees – Brokerage fees represent income earned related to providing brokerage transaction services, including commissions on equity and commodity trades, and fees for investment management, advisory and administration. The performance obligations related to transaction services are executing the specified trade and are priced according to the customer’s fee schedule. Such income is recognized at a point in time as the trade occurs and the performance obligation is fulfilled. The performance obligations related to investment management, advisory and administration include allocating customer assets across a wide range of mutual funds and other investments, on-going account monitoring and re-balancing of the portfolio. These performance obligations are satisfied over time and the related revenue is calculated monthly based on the assets under management of each customer. All material performance obligations are satisfied as of the end of each accounting period.

Bankcard fees – Bankcard fees primarily represent income earned from interchange revenue from MasterCard and Visa for the Company’s processing of debit, credit, HSA, and flexible spending account transactions. Additionally, the Company earns income and incentives related to various referrals of customers to card programs. The performance obligation for interchange revenue is the processing of each transaction through the Company’s access to the banking system. This performance obligation is completed for each individual transaction and income is recognized per transaction in accordance with interchange rates established by MasterCard and Visa. The performance obligations for various referral and incentive programs include either referring customers to certain card products or issuing exclusively branded cards for certain customer segments. The pricing of these incentive and referral programs are in accordance with the agreement with the individual card partner. These performance obligations are completed as the referrals are made or over a period of time when the Company is exclusively issuing branded cards. For the three months ended March 31, 2024 and March 31, 2023, the Company had $7.9 million and $10.0 million of expense, respectively, recorded within the Bankcard fees line on the Company’s Consolidated Statements of Income related to rebates and rewards programs that are outside of the scope of ASC 606.

These revenue streams are outside of the scope of ASC 606 and are recognized in accordance with the applicable U.S. GAAP. The remainder of Other income is primarily earned through transactions with personal banking customers, including wire transfer service charges, stop payment charges, and fees for items like money orders and cashier’s checks. The performance obligations of these types of fees are satisfied as transactions are completed and revenue is recognized upon transaction execution according to established fee schedules with the customers.

The Company had no material contract assets, contract liabilities, or remaining performance obligations as of March 31, 2024. Total receivables from revenue recognized under the scope of ASC 606 were $89.7 million and $86.6 million as of March 31, 2024 and December 31, 2023, respectively. These receivables are included as part of the Other assets line on the Company’s Consolidated Balance Sheets.

The following tables depict the disaggregation of revenue according to revenue stream and Business Segment for the three months ended March 31, 2024 and March 31, 2023. As stated in Note 8, “Business Segment Reporting,” for comparability purposes, amounts in all periods are based on methodologies in effect at March 31, 2024 and previously reported results have been reclassified in this Form 10-Q to conform to the Company’s current organizational structure.

Commitments, Contingencies and Guarantees

10. Commitments, Contingencies and Guarantees

In the normal course of business, the Company is a party to financial instruments with off-balance-sheet risk in order to meet the financing needs of its customers and to reduce its own exposure to fluctuations in interest rates. These financial instruments include commitments to extend credit, commercial letters of credit, standby letters of credit, and futures contracts. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Balance Sheets. The contractual or notional amount of those instruments reflects the extent of involvement the Company has in particular classes of financial instruments. Many

of the commitments expire without being drawn upon; therefore, the total amount of these commitments does not necessarily represent the future cash requirements of the Company.

The Company’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instruments for commitments to extend credit, commercial letters of credit, and standby letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.

The following table summarizes the Company’s off-balance sheet financial instruments as described above (in thousands):

	Contractual or Notional Amount
	March 31,		December 31,
	2024		2023
Commitments to extend credit for loans (excluding credit card loans)	$	12,687,851	$	12,831,831

Allowance for Credit Losses on Off-Balance Sheet Credit Exposure

The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancelable by the Company. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The estimate is based on expected utilization rates by portfolio segment. Utilization rates are influenced by historical trends and current conditions. The expected utilization rates are applied to the total commitment to determine the expected amount to be funded. The allowance for off-balance sheet credit exposure is calculated by applying portfolio segment expected credit loss rates to the expected amount to be funded.

The following categories of off-balance sheet credit exposures have been identified:

Revolving Lines of Credit: includes commercial, construction, agricultural, personal, and home-equity. Risks inherent to revolving lines of credit often are related to the susceptibility of an individual or business experiencing unpredictable cash flow or financial troubles, thus leading to payment default. During these financial troubles, the borrower could have less than desirable assets collateralizing the revolving line of credit. The financial strain the borrower is experiencing could lead to drawing against the line without the ability to pay the line down.

Non-Revolving Lines of Credit: includes commercial and personal. Lines that do not carry a revolving feature are generally associated with a specific expenditure or project, such as to purchase equipment or the construction of real estate. The predominate risk associated with non-revolving lines is the diversion of funds for other expenditures. If the funds get diverted, the contributory value to collateral suffers.

Letters of Credit: includes standby letters of credit. Generally, a standby letter of credit is established to provide assurance to the beneficiary that the applicant will perform certain obligations arising out of a separate transaction between the beneficiary and the applicant. These obligations might be the performance of a service or delivery of a product. If the obligations are not met, it gives the beneficiary the right to draw on the letter of credit.

The ACL for off-balance sheet credit exposures was $5.1 million as of both March 31, 2024 and December 31, 2023, and was recorded in the Accrued expenses and taxes line of the Company’s Consolidated Balance Sheets. There was no provision for off-balance sheet credit exposures recorded for the three months ended

March 31, 2024 or March 31, 2023.

Derivatives and Hedging Activities

11. Derivatives and Hedging Activities

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s loans and borrowings. The Company also has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk of the Company’s assets or liabilities. The Company has entered into an offsetting position for each of these derivative instruments with a matching instrument from another financial institution in order to minimize its net risk exposure resulting from such transactions.

Fair Values of Derivative Instruments on the Consolidated Balance Sheets

The table below presents the fair value of the Company’s derivative financial instruments as of March 31, 2024 and December 31, 2023. The Company’s derivative assets and derivative liabilities are located within Other assets and Other liabilities, respectively, on the Company’s Consolidated Balance Sheets.

Derivative fair values are determined using valuation techniques including discounted cash flow analysis on the expected cash flows from each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

This table provides a summary of the fair value of the Company’s derivative assets and liabilities as of March 31, 2024 and December 31, 2023 (in thousands):

	Derivative Assets				Derivative Liabilities
	March 31,		December 31,		March 31,		December 31,
Fair Value	2024		2023		2024		2023
Interest Rate Products:
Derivatives not designated as hedging instruments	$	113,585	$	99,574	$	119,491	$	105,016
Derivatives designated as hedging instruments		107,328		61,922		38		67
Total	$	220,913	$	161,496	$	119,529	$	105,083

Fair Value Hedges of Interest Rate Risk

The Company is exposed to changes in the fair value of certain of its fixed-rate assets and liabilities due to changes in interest rates. Interest rate swaps designated as fair value hedges involve making fixed rate payments to a counterparty in exchange for the Company receiving variable rate payments over the life of the agreements without the exchange of the underlying notional amount. As of both March 31, 2024 and December 31, 2023, the Company did not have any interest rate swaps that were designated as fair value hedges of interest rate risk.

During 2022 and 2023, the Company terminated 10 fair value hedges of interest rate risk associated with the Company's municipal bond securities. For the three months ended March 31, 2024 and 2023 the Company reclassified $2.6 million and $1.1 million, respectively, from AOCI to Interest income in connection with these terminated hedges. The unrealized gain on the terminated fair value hedges remaining in AOCI was $53.0 million net of tax, and $55.0 million net of tax, as of March 31, 2024 and December 31, 2023, respectively. The hedging adjustments will be amortized through the contractual maturity date of each respective hedged item.

For derivatives designated and that qualify as fair value hedges, the gain or loss on the derivative as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in Interest income in the Consolidated Statements of Income.

Cash Flow Hedges of Interest Rate Risk

The Company’s objective in using interest rate derivatives is to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps, floors, and floor spreads as part of its interest rate risk management strategy. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. As of March 31, 2024 and December 31, 2023, the Company had two interest rate swaps that were designated as cash flow hedges of interest rate risk associated with the Company’s variable-rate subordinated debentures issued by Marquette Capital Trusts III and IV. These swaps had an aggregate notional amount of $51.5 million at both March 31, 2024 and December 31, 2023.

Interest rate floors designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates fall below the strike rate on the contract in exchange for an upfront premium. Interest rate floor spreads designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty if interest rates fall below the purchased floor rate on the contract in exchange for an upfront premium, and involve payment of variable-rate amounts to the counterparty if interest rates fall below the sold floor rate on the contract. As of March 31, 2024, the Company had eight interest rate floors and floor spreads with an aggregate notional amount of $2.0 billion that were designated as cash flow hedges of interest rate risk. As of December 31, 2023, the Company had three interest rate floors and floor spreads with an aggregate notional amount of $1.0 billion that were designated as cash flow hedges of interest rate risk.

In 2020, the Company terminated an interest rate floor designated as a cash flow hedge. The gross unrealized gain on the terminated interest rate floor remaining in AOCI was $1.2 million net of tax, and $2.0 million net of tax, as of March 31, 2024 and December 31, 2023, respectively. The unrealized gain will be reclassified into Interest income as the underlying forecasted transactions impact earnings through the original maturity of the hedged forecasted transactions.

For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and is subsequently reclassified into interest expense and interest income in the period during which the hedged forecasted transaction affects earnings. Amounts reported in AOCI related to interest rate swap derivatives will be reclassified to Interest expense as interest payments are received or paid on the Company’s hedged items. Amounts reported in AOCI related to interest rate floor and floor spread derivatives will be reclassified to Interest income as interest payments are received or paid on the Company’s hedged items. The Company expects to reclassify $1.2 million from AOCI as a reduction to Interest expense and $1.9 million from AOCI as a reduction to Interest income during the next 12 months. As of March 31, 2024, the Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a maximum period of 12.5 years.

Non-designated Hedges

The remainder of the Company’s derivatives are not designated in qualifying hedging relationships. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously offset by interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The changes in the fair value of both the customer swaps and the offsetting swaps are recognized in Other noninterest expense in the Consolidated Statements of Income. As of March 31, 2024, the Company had 268 interest rate swaps with an aggregate notional amount of $4.7 billion related to this program. As of December 31, 2023, the Company had 258 interest rate swaps with an aggregate notional amount of $4.3 billion.

Credit-risk-related Contingent Features

The Company has agreements with certain of its derivative counterparties that contain a provision that if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations.

The Company has minimum collateral posting thresholds with certain of its derivative counterparties. At March 31, 2024, the Company had not posted any collateral as there were no derivatives in a net liability position. If the Company had breached any of these provisions at March 31, 2024, it could have been required to settle its obligations under the agreements at the termination value.

Fair Value Measurements

12. Fair Value Measurements

The following table presents information about the Company’s assets and liabilities measured at fair value on a recurring basis as of March 31, 2024, and December 31, 2023, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value.

Fair values determined by Level 1 inputs utilize quoted prices in active markets for identical assets and liabilities that the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the hierarchy. In such cases, the fair value is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

Valuation methods for instruments measured at fair value on a recurring basis

The following methods and assumptions were used to estimate the fair value of each class of financial instruments measured on a recurring basis:

Trading Securities Fair values for trading securities (including financial futures), are based on quoted market prices where available. If quoted market prices are not available, fair values are based on quoted market prices for similar securities.

Securities Available for Sale Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Prices are provided by third-party pricing services and are based on observable market inputs. On an annual basis, the Company compares a sample of these prices to other independent sources for the same securities. Additionally, throughout the year, if securities are sold, comparisons are made between the pricing services prices and the market prices at which the securities were sold. Variances are analyzed, and, if appropriate, additional research is conducted with the third-party pricing services. Based on this research, the pricing services may affirm or revise their quoted price. No significant adjustments have been made to the prices provided by the pricing services. The pricing services also provide documentation on an ongoing basis that includes reference data, inputs and methodology by asset class, which is reviewed to ensure that security placement within the fair value hierarchy is appropriate.

Equity securities with readily determinable fair values Fair values are based on quoted market prices.

Company-owned Life Insurance Fair value is equal to the cash surrender value of the life insurance policies.

Bank-owned Life Insurance Fair value is equal to the cash surrender value of the life insurance policies.

Derivatives Fair values are determined using valuation techniques including discounted cash flow analysis on the expected cash flows from each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees.

Securities sold not yet purchased Fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Prices are provided by third-party pricing services and are based on observable market inputs.

Valuation methods for instruments measured at fair value on a non-recurring basis

The following methods and assumptions were used to estimate the fair value of each class of financial instruments measured on a non-recurring basis:

Collateral Dependent Assets Collateral dependent assets are assets evaluated as part of the ACL on an individual basis. Those assets for which there is an associated allowance are considered financial assets measured at fair value on a non-recurring basis. Adjustments are recorded on certain assets to reflect write-downs that are based on the external appraised value of the underlying collateral. The external appraisals are generally based on recent sales of comparable properties which are then adjusted for the unique characteristics of the property being valued. In the case of non-real estate collateral, reliance is placed on a variety of sources, including external estimates of value and judgments based on the experience and expertise of internal specialists within the Company’s property management group and the Company’s credit department. The valuation of collateral dependent assets and impaired

loans are reviewed on a quarterly basis. Because many of these inputs are not observable, the measurements are classified as Level 3.

Other real estate owned Other real estate owned consists of loan collateral which has been repossessed through foreclosure. This collateral is comprised of commercial and residential real estate and other non-real estate property, including auto, recreational and marine vehicles. Other real estate owned is recorded as held for sale initially at the fair value of the collateral less estimated selling costs. The initial valuation of the foreclosed property is obtained through an appraisal process similar to the process described in the collateral dependent/impaired loans paragraph above. Subsequent to foreclosure, valuations are reviewed quarterly and updated periodically, and the assets may be marked down further, reflecting a new cost basis. Fair value measurements may be based upon appraisals, third-party price opinions, or internally developed pricing methods and those measurements are classified as Level 3.

Fair value disclosures require disclosure of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or non-recurring basis.

The estimated fair value of the Company’s financial instruments at March 31, 2024 and December 31, 2023 are as follows (in thousands):

Cash and short-term investments The carrying amounts of cash and due from banks, federal funds sold and resell agreements are reasonable estimates of their fair values.

Securities held to maturity For U.S. Agency and mortgage-backed securities, as well as general obligation bonds in the State and political subdivision portfolio, fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Prices are provided by third-party pricing services and are based on observable market inputs. On an annual basis, the Company compares a sample of these prices to other independent sources for the same securities. Variances are analyzed, and, if appropriate, additional research is conducted with the third-party pricing services. Based on this research, the pricing services may affirm or revise their quoted price. No significant adjustments have been made to the prices provided by the pricing services. The pricing services also provide documentation on an ongoing basis that includes reference data, inputs and methodology by asset class, which is reviewed to ensure that security placement within the fair value hierarchy is appropriate. For private placement bonds in the State and political subdivision portfolio, fair values are estimated by discounting the future cash flows using current market rates.

Other securities Amount consists of FRB and FHLB stock held by the Company, equity securities with readily determinable fair values, and equity securities without readily determinable fair values, including equity-method investments and other miscellaneous investments. The carrying amount of the FRB and FHLB stock equals its fair value because the shares can only be redeemed by the FRB and FHLB at their carrying amount. Equity securities with readily determinable fair values are measured at fair value using quoted market prices. Equity securities without readily determinable fair values are carried at cost, which approximates fair value.

Loans Fair values are estimated for portfolios with similar financial characteristics. Loans are segregated by type, such as commercial, real estate, consumer, and credit card. Each loan category is further segmented into fixed and variable interest rate categories. The fair value of loans is estimated by discounting the future cash flows. The

discount rates used are estimated using comparable market rates for similar types of instruments adjusted to be commensurate with the credit risk, overhead costs, and optionality of such instruments.

Demand and savings deposits The fair value of demand deposits and savings accounts was the amount payable on demand at period-end.

Time deposits The fair value of fixed-maturity certificates of deposit is estimated by discounting the future cash flows using the rates that are currently offered for deposits of similar remaining maturities.

Other borrowings The carrying amounts of federal funds purchased, repurchase agreements and other short-term debt are reasonable estimates of their fair value because of the short-term nature of their maturities. Federal funds purchased are classified as Level 1 based on availability of quoted market prices and repurchase agreements and other short-term debt are classified as Level 2.

Long-term debt Rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate fair value of existing debt.

Other off-balance sheet instruments The fair value of loan commitments and letters of credit are determined based on the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and the present creditworthiness of the counterparties. Neither the fees earned during the year on these instruments nor their fair value at period-end are significant to the Company’s consolidated financial position.

Summary of Significant Accounting Policies (Policies)

3 Months Ended

Mar. 31, 2024

Accounting Policies [Abstract]

Nature Of Operations

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (U.S. GAAP) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. These estimates and assumptions also impact reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. A summary of the significant accounting policies to assist the reader in understanding the financial presentation is provided in the Notes to Consolidated Financial Statements in the Form 10-K.

Cash and cash equivalents

Cash and cash equivalents

Cash and cash equivalents include Cash and due from banks and amounts due from the Federal Reserve Bank (FRB). Cash on hand, cash items in the process of collection, and amounts due from correspondent banks are included in Cash and due from banks. Amounts due from the FRB are interest-bearing for all periods presented and are included in the Interest-bearing due from banks line on the Company’s Consolidated Balance Sheets.

This table provides a summary of cash and cash equivalents as presented on the Consolidated Statements of Cash Flows as of March 31, 2024 and March 31, 2023 (in thousands):

	March 31,
	2024		2023
Due from the FRB	$	6,586,145	$	3,051,056
Cash and due from banks		356,963		472,248
Cash and cash equivalents at end of period	$	6,943,108	$	3,523,304

Also included in the Interest-bearing due from banks, but not considered cash and cash equivalents, are interest-bearing accounts held at other financial institutions, which totaled $87.0 million and $70.1 million at March 31, 2024 and March 31, 2023, respectively.

Per Share Data

Per Share Data

Basic net income per share is computed based on the weighted average number of shares of common stock outstanding during each period. Diluted quarter-to-date net income per share includes the dilutive effect of 257,348 and 311,546 shares issuable upon the exercise of stock options and nonvested restricted stock units granted by the Company that were outstanding at March 31, 2024 and 2023, respectively.

Certain options and restricted stock units issued under employee benefit plans were excluded from the computation of diluted earnings per share because they were anti-dilutive. For the three months ended March 31, 2024, there were no outstanding stock options and restricted stock units excluded from the computation of diluted income per share. For the three months ended March 31, 2023, there were 166,578 outstanding stock options or restricted stock units excluded from the computation of diluted income per share because their inclusion would have been anti-dilutive.

Derivatives

Derivatives

The Company records all derivatives on the Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Currently, ten of the Company’s derivatives are designated in qualifying hedging relationships. The remainder of the Company’s derivatives are not designated in qualifying hedging relationships, as the derivatives are not used to manage risks within the Company’s assets or liabilities. All changes in fair value of the Company’s non-designated derivatives and fair value hedges are recognized directly in earnings. Changes in fair value of the Company’s cash flow hedges are recognized in accumulated other comprehensive income (AOCI) and are reclassified to earnings when the hedged transaction affects earnings.
