NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

June 30, 2024 (Unaudited)

1. Principles of Consolidation and Presentation

The accompanying consolidated financial statements include the accounts of Commerce Bancshares, Inc. and all majority-owned subsidiaries (the Company). Most of the Company's operations are conducted by its subsidiary bank, Commerce Bank (the Bank). The consolidated financial statements in this report have not been audited by an independent registered public accounting firm, but in the opinion of management, all adjustments necessary to present fairly the financial position and the results of operations for the interim periods have been made. All such adjustments are of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated. Certain reclassifications were made to 2023 data to conform to current year presentation. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and revenues and expenses for the periods. Actual results could differ significantly from those estimates. Management has evaluated subsequent events for potential recognition or disclosure. The results of operations for the six month period ended June 30, 2024 are not necessarily indicative of results to be attained for the full year or any other interim period.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company's most recent Annual Report on Form 10-K, containing the latest audited consolidated financial statements and notes thereto.

2. Loans and Allowance for Credit Losses

Allowance for credit losses

The allowance for credit losses is measured using an average historical loss model which incorporates relevant information about past events (including historical credit loss experience on loans with similar risk characteristics), current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the loans. The allowance for credit losses is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics including borrower type, collateral type and expected credit loss patterns. Loans that do not share similar risk characteristics, primarily large loans on non-accrual status, are evaluated on an individual basis.

For loans evaluated for credit losses on a collective basis, average historical loss rates are calculated for each pool using the Company’s historical net charge-offs (combined charge-offs and recoveries by observable historical reporting period) and outstanding loan balances during a lookback period. Lookback periods can be different based on the individual pool and represent management’s credit expectations for the pool of loans over the remaining contractual life. In certain loan pools, if the Company’s own historical loss rate is not reflective of the loss expectations, the historical loss rate is augmented by industry and peer data. The calculated average net charge-off rate is then adjusted for current conditions and reasonable and supportable forecasts. These adjustments increase or decrease the average historical loss rate to reflect expectations of future losses given a single path economic forecast of key macroeconomic variables including GDP, disposable income, various interest rates, unemployment rate, consumer price index (CPI) inflation rate, housing price index (HPI), commercial real estate price index (CREPI) and market volatility. The adjustments are based on results from various regression models projecting the impact of the macroeconomic variables to loss rates. The forecast is used for a reasonable and supportable period before reverting back to historical averages using a straight-line method. The forecast-adjusted loss rate is applied to the amortized cost of loans over the remaining contractual lives, adjusted for expected prepayments. The contractual term excludes expected extensions (except for contractual extensions at the option of the customer), renewals and modifications. Credit cards and certain similar consumer lines of credit do not have stated maturities and therefore, for these loan classes, remaining contractual lives are determined by estimating future cash flows expected to be received from customers until payments have been fully allocated to outstanding balances. Additionally, the allowance for credit losses considers other qualitative factors not included in historical loss rates or macroeconomic forecast such as changes in portfolio composition, underwriting practices, or significant unique events or conditions.

10

Key assumptions in the Company’s allowance for credit loss model include the economic forecast, the reasonable and supportable period, forecasted macro-economic variables, prepayment assumptions and qualitative factors applied for portfolio composition changes, underwriting practices, or significant unique events or conditions. The assumptions utilized in estimating the Company’s allowance for credit losses at June 30, 2024 and March 31, 2024 are discussed below.

Key Assumption	June 30, 2024	March 31, 2024
Overall economic forecast	•Economic growth expected to slightly cool with no significant rise in layoffs or unemployment rate •Inflation expected to moderate •Expectations the Federal Reserve will start cutting rates in September 2024	•Economic strength is visible in the strong labor market •Fiscal policy is forecasted to be a modest drag on GDP •There are expectations that the Federal Reserve will start cutting rates in 2nd quarter 2024
Reasonable and supportable period and related reversion period	•Reasonable and supportable period of one year •Reversion to historical average loss rates within two quarters using a straight-line method	•Reasonable and supportable period of one year •Reversion to historical average loss rates within two quarters using a straight-line method
Forecasted macro-economic variables	•Unemployment rate ranges from 4.0% to 4.2% during the reasonable and supportable forecast period •Real GDP growth ranges from 1.7% to 2.2% •BBB corporate yield from 5.0% to 5.4% •Housing Price Index from 321.2 to 327.1	•Unemployment rate ranges from 3.9% to 4.1% during the reasonable and supportable forecast period •Real GDP growth ranges from 1.5% to 3.0% •BBB corporate yield from 4.7% to 5.1% •Housing Price Index from 312.1 to 316.6
Prepayment assumptions	Commercial loans •Pools ranging from 0% to 5% Personal banking loans •Ranging from 7.7% to 22.7% for most loan pools •Consumer credit cards 66.6%	Commercial loans •Pools ranging from 0% to 5% Personal banking loans •Ranging from 6.2% to 21.6% for most loan pools •Consumer credit cards 66.6%
Qualitative factors	Added qualitative factors related to: •Changes in the composition of the loan portfolios •Certain industries experiencing stress or emerging concerns within the portfolio •Certain portfolios sensitive to unusually high rate of inflation and supply chain issues •Loans downgraded to special mention, substandard, or non-accrual status •Certain portfolios where the model assumptions do not capture all identified loss risk	Added qualitative factors related to: •Changes in the composition of the loan portfolios •Certain stressed industries within the portfolio •Certain portfolios sensitive to unusually high rate of inflation and supply chain issues •Loans downgraded to special mention, substandard, or non-accrual status •Certain portfolios where the model assumptions do not capture all identified loss risk

The liability for unfunded lending commitments utilizes the same model as the allowance for credit losses on loans, however, the liability for unfunded lending commitments incorporates an assumption for the portion of unfunded commitments that are expected to be funded.

Sensitivity in the Allowance for Credit Loss model

The allowance for credit losses is an estimate that requires significant judgment including projections of the macro-economic environment. The forecasted macro-economic environment continuously changes which can cause fluctuations in the estimate of expected credit losses.

The current forecast projects continued low unemployment. It is expected that the Federal Reserve will start cutting rates in September of 2024 and fiscal policy will be maintained.

Updated information on inflation and labor market trends could impact the Federal Reserve's decision on the timing and degree of rate reductions. The market's response to these events along with other economic, political, and social developments regionally, nationally, and even globally could significantly modify economic projections used in the estimation of the allowance for credit losses. The upcoming presidential election could result in policy changes that might also impact the estimation of the allowance for credit losses.

11

Potential changes in any one economic variable may or may not affect the overall allowance because a variety of economic variables and inputs are considered in estimating the allowance, and changes in those variables and inputs may not occur at the same rate, may not be consistent across product types, and may have offsetting impacts to other changing variables and inputs.

A summary of the activity in the allowance for credit losses on loans and the liability for unfunded lending commitments for the three and six months ended June 30, 2024 and 2023, respectively, follows:

Credit quality indicators

The following table provides information about the credit quality of the Commercial loan portfolio. The Company utilizes an internal risk rating system comprised of a series of grades to categorize loans according to perceived risk associated with the expectation of debt repayment based on borrower specific information including, but not limited to, current financial information, historical payment experience, industry information, collateral levels and collateral types. The “pass” category consists of a range of loan grades that reflect increasing, though still acceptable, risk. A loan is assigned the risk rating at origination and then monitored throughout the contractual term for possible risk rating changes. Movement of risk through the various grade levels in the “pass” category is monitored for early identification of credit deterioration. The “special mention” rating is applied to loans where the borrower exhibits negative financial trends due to borrower specific or systemic conditions that, if left uncorrected, threaten its capacity to meet its debt obligations. The borrower is believed to have sufficient financial flexibility to react to and resolve its negative financial situation. It is a transitional grade that is closely monitored for improvement or deterioration. The “substandard” rating is applied to loans where the borrower exhibits well-defined weaknesses that jeopardize its continued performance and are of a severity that the distinct possibility of default exists. Loans are placed on “non-accrual” when management does not expect to collect payments consistent with acceptable and agreed upon terms of repayment.

All loans are analyzed for risk rating updates annually. For larger loans, rating assessments may be more frequent if relevant information is obtained earlier through debt covenant monitoring or overall relationship management. Smaller loans are monitored as identified by the loan officer based on the risk profile of the individual borrower or if the loan becomes past

due related to credit issues. Loans rated Special Mention, Substandard or Non-accrual are subject to quarterly review and monitoring processes. In addition to the regular monitoring performed by the lending personnel and credit committees, loans are subject to review by a credit review department which verifies the appropriateness of the risk ratings for the loans chosen as part of its risk-based review plan.

The risk category of loans in the Commercial portfolio as of June 30, 2024 and December 31, 2023 are as follows:

Collateral-dependent loans

The Company's collateral-dependent loans are comprised of large loans on non-accrual status. The Company requires that collateral-dependent loans are either over-collateralized or carry collateral equal to the amortized cost of the loan. The following table presents the amortized cost basis of collateral-dependent loans as of June 30, 2024 and December 31, 2023.

Other Personal Banking loan information

As noted above, the credit quality of Personal Banking loans is monitored primarily on the basis of aging/delinquency, and this information is provided in the table in the above section on "Credit quality indicators." In addition, FICO scores are obtained and updated on a quarterly basis for most of the loans in the Personal Banking portfolio. This is a published credit score designed to measure the risk of default by taking into account various factors from a borrower's financial history and is considered supplementary information utilized by the Company, as management does not consider this information in evaluating the allowance for credit losses on loans. The Bank normally obtains a FICO score at the loan's origination and renewal dates, and updates are obtained on a quarterly basis. Excluded from the table below are certain personal real estate loans for which FICO scores are not obtained because the loans generally pertain to commercial customer activities and are often underwritten with other collateral considerations. These loans totaled $170.1 million at June 30, 2024 and $168.9 million at December 31, 2023. The table also excludes consumer loans related to the Company's patient healthcare loan program, which totaled $220.5 million at June 30, 2024 and $211.3 million at December 31, 2023. As the healthcare loans are guaranteed by the hospital, customer FICO scores are not obtained for these loans. The personal real estate loans and consumer loans excluded below totaled less than 7% of the Personal Banking portfolio. For the remainder of loans in the Personal Banking portfolio, the table below shows the percentage of balances outstanding at June 30, 2024 and December 31, 2023 by FICO score.

Modifications for borrowers experiencing financial difficulty

When borrowers are experiencing financial difficulty, the Company may agree to modify the contractual terms of a loan to a borrower in order to assist the borrower in repaying principal and interest owed to the Company.

The Company's modifications of loans to borrowers experiencing financial difficulty are generally in the form of term extensions, repayment plans, payment deferrals, forbearance agreements, interest rate reductions, forgiveness of interest and/or fees, or any combination thereof. Commercial loans modified to borrowers experiencing financial difficulty are primarily loans that are substandard or non-accrual, where the maturity date was extended. Modifications on personal real estate loans are primarily those placed on forbearance plans, repayment plans, or deferral plans where monthly payments are suspended for a period of time or past due amounts are paid off over a certain period of time in the future or set up as a balloon payment at maturity. Modifications to certain credit card and other small consumer loans are often modified under debt counseling programs that can reduce the contractual rate or, in certain instances, forgive certain fees and interest charges. Other consumer loans modified to borrowers experiencing financial difficulty consist of various other workout arrangements with consumer customers.

The estimate of lifetime expected losses utilized in the allowance for credit losses model is developed using average historical experience on loans with similar risk characteristics, which includes losses from modifications of loans to borrowers experiencing financial difficulty. As a result, a change to the allowance for credit losses is generally not recorded upon

20

modification. For modifications to loans made to borrowers experiencing financial difficulty that are placed on non-accrual status, the Company determines the allowance for credit losses on an individual evaluation, using the same process that it utilizes for other loans on non-accrual status. Modifications made to commercial loans which are not on non-accrual status for borrowers experiencing financial difficulty are collectively evaluated based on internal risk rating, loan type, delinquency, historical experience, and current economic factors. Modifications made to borrowers experiencing financial difficulty for personal banking loans which are not on non-accrual status are collectively evaluated based on loan type, delinquency, historical experience, and current economic factors.

If a loan to a borrower experiencing financial difficulty is modified and subsequently deemed uncollectible, the allowance for credit losses continues to be based on individual evaluation, if that loan is already on non-accrual status. For those loans, the allowance for credit losses is estimated using discounted expected cash flows or the fair value of collateral. If an accruing loan made to a borrower experiencing financial difficulty is modified and subsequently deemed uncollectible, the loan's risk rating is downgraded to non-accrual status and the loan's related allowance for credit losses is determined based on individual evaluation, or if necessary, the loan is charged off and collection efforts begin.

The following tables summarize the financial impact of loan modifications and payment deferrals during the three and six months ended June 30, 2024 and June 30, 2023.

The Company had commitments of $7.0 million and $28.4 million at June 30, 2024 and December 31, 2023, respectively, to lend additional funds to borrowers experiencing financial difficulty and for whom the Company has modified the terms of loans in the form of an interest rate reduction; an other-than-insignificant payment delay; forgiveness of principal, interest, or fees; or a term extension during the current reporting period.

The following tables provide the amortized cost basis at June 30, 2024 of loans to borrowers experiencing financial difficulty that had a payment default during the three and six months ended June 30, 2024 and were modified within the 12 months preceding the payment default, as well as the amortized cost basis at June 30, 2023 of loans to borrowers experiencing financial difficulty that had a payment default during the three and six months ended June 30, 2023 and had been modified on or after January 1, 2023 (the date we adopted ASU 2022-02). For purposes of this disclosure, the Company considers "default" to mean 90 days or more past due as to interest or principal.

Loans held for sale

The Company designates certain long-term fixed rate personal real estate loans as held for sale, and the Company has elected the fair value option for these loans. The election of the fair value option aligns the accounting for these loans with the related economic hedges discussed in Note 11. The loans are primarily sold to Federal Home Loan Mortgage Corporation (FHLMC) and Federal National Mortgage Association (FNMA). At June 30, 2024, the fair value of these loans was $2.2 million, and the unpaid principal balance was $2.2 million.

The Company also designates certain student loan originations as held for sale. The borrowers are credit-worthy students who are attending colleges and universities. The loans are intended to be sold in the secondary market, and the Company maintains contracts with Sallie Mae to sell the loans within 210 days after the last disbursement to the student. These loans are carried at lower of cost or fair value, which at June 30, 2024 totaled $448 thousand.

At June 30, 2024, none of the loans held for sale were on non-accrual status or 90 days past due and still accruing interest.

Foreclosed real estate/repossessed assets

The Company’s holdings of foreclosed real estate totaled $143 thousand and $270 thousand at June 30, 2024 and December 31, 2023, respectively, and included in those amounts were $143 thousand and $270 thousand at June 30, 2024 and December 31, 2023, respectively, of foreclosed residential real estate properties held as a result of obtaining physical possession. Personal property acquired in repossession, generally autos, totaled $2.2 million and $1.8 million at June 30, 2024 and December 31, 2023. Upon acquisition, these assets are recorded at fair value less estimated selling costs at the date of foreclosure, establishing a new cost basis. They are subsequently carried at the lower of this cost basis or fair value less estimated selling costs.

3. Investment Securities

Investment securities consisted of the following at June 30, 2024 and December 31, 2023.

(1)Accrued interest receivable totaled $26.4 million and $28.9 million at June 30, 2024 and December 31, 2023, respectively, and was included within other assets on the consolidated balance sheets.

Most of the Company’s investment securities are classified as available for sale debt securities, and this portfolio is discussed in more detail below. The Company’s equity securities are also discussed below. Other investment securities include Federal Reserve Bank (FRB) stock, Federal Home Loan Bank (FHLB) stock, and investments in portfolio concerns held by the Company’s private equity subsidiary. FRB stock and FHLB stock are held for debt and regulatory purposes. Investment in FRB stock is based on the capital structure of the investing bank, and investment in FHLB stock is tied to the asset size of the borrowing bank and the level of borrowings from the FHLB. These holdings are carried at cost. The Company’s private equity investments are carried at estimated fair value.

Equity Securities

The Company’s equity securities portfolio includes common and preferred stock with readily determinable fair values as well as equity securities with no readily determinable fair value. The Company has elected to measure equity securities with no readily determinable fair value at cost minus impairment, if any, plus or minus changes resulting from observable price changes for the identical or similar investment of the same issuer. At March 31, 2024, this portfolio included the Company’s 823,447 shares of Visa Inc. (“Visa”) Class B-1 common stock (formerly Class B common stock), which were held by Commerce Bancshares, Inc. The Company’s Visa Class B-1 shares had a carrying value of zero at March 31, 2024, as there had not been observable price changes in orderly transactions for identical or similar investments of the same issuer.

24

On April 8, 2024, Visa announced the commencement of a public offering to permit the exchange of its Class B-1 common stock for a combination of shares of its Class B-2 common stock and its Class C common stock (“Exchange Offer”). The Company tendered all of its Visa Class B-1 shares pursuant to the Exchange Offer. On May 3, 2024, the Exchange Offer closed, and in exchange for its 823,447 shares of Visa Class B-1 common stock, the Company received 411,723 shares of Visa Class B-2 common stock (which will be convertible under certain circumstances, as further described below, into Visa’s publicly traded Class A common stock at an initial rate of 1.5875 shares of Class A common for each share of Class B-2 common stock, subject to adjustment) and 163,404 shares of Visa Class C common stock which will automatically convert into four shares of Visa's Class A common stock (subject to future adjustments for any stock splits, recapitalizations or similar transactions) upon any transfer to a person other than a Visa member or an affiliate of a Visa member.

As a condition of participating in the exchange, the Company entered into a Makewhole Agreement with Visa that provides for cash payments to Visa to the extent (if any) that future adjustments to the conversion ratio for the Visa Class B-2 common stock to Class A common stock cause such ratio to fall below zero. Changes to the conversion ratio occur when Visa deposits funds to a litigation escrow established by Visa to pay settlements for certain covered litigation that pre-dated Visa’s initial public offering, for which Visa has been effectively indemnified by Visa USA members through reductions to the conversion ratio for its Class B-1 common stock. The purpose of the Makewhole Agreement is to preserve the economic benefit of these adjustments to the Class B-1 conversion ratio for the benefit of Visa’s Class A and Class C common stockholders following the exchange. As further described in Visa’s related Issuer Tender Offer Statement on Schedule TO and Prospectus, each dated April 8, 2024, publicly filed with the U. S. Securities and Exchange Commission, both the Makewhole Agreement and the related escrow fund and transfer restrictions on Visa’s Class B-1 common stock and the new Class B-2 common stock will terminate whenever the covered litigation is ultimately resolved, at which future date outstanding shares of Visa Class B-2 common stock will be convertible into shares of its Class A common stock at the then-applicable conversion ratio.

As a result of the exchange, the Company elected the measurement alternative approach for its Visa Class C common stock and marked the stock to fair value, recording a gain based on the conversion privilege of the Visa Class C common stock and the closing price of Visa Class A common stock. During the second quarter of 2024, the Company sold 436 thousand shares of Visa Class A common stock at an average price of $274.91, resulting in proceeds of $119.8 million. The Company’s remaining 54 thousand Visa Class C shares had a fair value of $57.2 million at June 30, 2024, and are subject to limited transfer restrictions that end on August 1, 2024. These shares are expected to continue to be marked to fair value on a recurring basis using the Visa Class A shares as evidence of orderly transactions between market participants for similar securities issued by Visa. The Company’s Visa Class B-2 common stock will continue to be carried at cost of $0 as the Company elected the measurement alternative approach for these shares as well, and there are not observable price changes in orderly transactions for identical or similar investments of the same issuer for the Visa Class B-2 shares held by the Company.

Available for sale debt securities portfolio

The majority of the Company’s investment portfolio is comprised of available for sale debt securities, which are carried at fair value with changes in fair value reported in accumulated other comprehensive income (AOCI). A summary of the available for sale debt securities by maturity groupings as of June 30, 2024 is shown below. The investment portfolio includes agency mortgage-backed securities, which are guaranteed by agencies such as FHLMC, FNMA, and Government National Mortgage Association (GNMA), in addition to non-agency mortgage-backed securities, which have no guarantee but are collateralized by commercial and residential mortgages. Also included are certain other asset-backed securities, which are primarily collateralized by credit cards, automobiles, student loans, and commercial loans. These securities differ from traditional debt securities primarily in that they may have uncertain maturity dates and are priced based on estimated prepayment rates on the underlying collateral.

Total available for sale debt securities	$	9,608,044	$	8,534,271

Investments in U.S. government and federal agency obligations include U.S. Treasury inflation-protected securities, which totaled $399.7 million, at fair value, at June 30, 2024. Interest earned on these securities increases with inflation and decreases with deflation, as measured by the non-seasonally adjusted Consumer Price Index (CPI-U). At maturity, the principal paid is the greater of an inflation-adjusted principal or the original principal.

Allowance for credit losses on available for sale debt securities

Securities for which fair value is less than amortized cost are reviewed for impairment. Special emphasis is placed on securities whose credit rating has fallen below Baa3 (Moody's) or BBB- (Standard & Poor's), whose fair values have fallen more than 20% below purchase price, or those which have been identified based on management’s judgment. These securities are placed on a watch list and cash flow analyses are prepared on an individual security basis. Certain securities are analyzed using a projected cash flow model, discounted to present value, and compared to the current amortized cost bases of the securities. The model uses input factors such as cash flow projections, contractual payments required, expected delinquency rates, credit support from other tranches, prepayment speeds, collateral loss severity rates (including loan to values), and various other information related to the underlying collateral. Securities not analyzed using the cash flow model are analyzed by reviewing credit ratings, credit support agreements, and industry knowledge to project future cash flows and any possible credit impairment.

26

At June 30, 2024, the fair value of securities on this watch list was $1.8 billion compared to $1.2 billion at December 31, 2023. Almost all of the securities included on the Company's watch list in the current quarter were experiencing unrealized loss positions due to the significant increase in interest rates and were analyzed outside of the cash flow model. At June 30, 2024, the securities on the Company's watch list that were not deemed to be solely related to increasing interest rates were securities backed by government-guaranteed student loans and are expected to perform as contractually required. As of June 30, 2024, the Company did not identify any securities for which a credit loss exists, and for the six months ended June 30, 2024 and 2023, the Company did not recognize a credit loss expense on any available for sale debt securities.

The table below summarizes debt securities available for sale in an unrealized loss position, aggregated by length of loss period, for which an allowance for credit losses has not been recorded at June 30, 2024 and December 31, 2023. Unrealized losses on these available for sale securities have not been recognized into income because after review, the securities were deemed not to be impaired. The unrealized losses on these securities are primarily attributable to changes in interest rates and current market conditions. At June 30, 2024, the Company does not intend to sell the securities, nor is it anticipated that it would be required to sell any of these securities at a loss.

The entire available for sale debt portfolio included $8.0 billion of securities that were in a loss position at June 30, 2024, compared to $9.6 billion at December 31, 2023.  The total amount of unrealized loss on these securities was $1.1 billion at June 30, 2024, a decrease of $144.4 million compared to the unrealized loss at December 31, 2023.  Securities with significant unrealized losses are discussed in the "Allowance for credit losses on available for sale debt securities" section above.

Net gains on investment securities for the six months ended June 30, 2024 were mainly comprised of net gains of $178.3 million on equity investments and net gains in fair value of $12.8 million recorded on private equity investments. These gains were largely offset by net losses of $187.5 million on sales of available for sale securities.

Subsequent to the successful close of the Exchange Offer in early May 2024, the Company approved and executed a plan to reposition a portion of its available for sale debt securities portfolio through the sale of securities with an amortized cost of $1.2 billion. The securities that the Company sold had a yield of approximately 2.1%, which resulted in a loss of $179.1 million, and the Company reinvested $928.8 million of the proceeds into U.S. Treasury securities yielding approximately 4.6%.

Pledged securities

At June 30, 2024, securities totaling $6.5 billion in fair value were pledged to secure public fund deposits, securities sold under agreements to repurchase, trust funds, and borrowings at the FRB and FHLB, compared to $7.5 billion at December 31, 2023. Except for obligations of various government-sponsored enterprises such as FNMA, FHLB and FHLMC, no investment in a single issuer exceeded 10% of stockholders’ equity.

5. Guarantees

The Company, as a provider of financial services, routinely issues financial guarantees in the form of financial and performance standby letters of credit. Standby letters of credit are contingent commitments issued by the Company generally to guarantee the payment or performance obligation of a customer to a third party. While these represent a potential outlay by the Company, a significant amount of the commitments may expire without being drawn upon. The Company has recourse against the customer for any amount it is required to pay to a third party under a standby letter of credit. The letters of credit are subject to the same credit policies, underwriting standards and approval process as loans made by the Company. Most of the standby letters of credit are secured, and in the event of nonperformance by customers, the Company has rights to the underlying collateral, which could include commercial real estate, physical plant and property, inventory, receivables, cash and marketable securities.

Upon issuance of standby letters of credit, the Company recognizes a liability for the fair value of the obligation undertaken, which is estimated to be equivalent to the amount of fees received from the customer over the life of the agreement. At June 30, 2024, that net liability was $3.6 million, which will be accreted into income over the remaining life of the respective commitments. The contractual amount of these letters of credit, which represents the maximum potential future payments guaranteed by the Company, was $633.6 million at June 30, 2024.

The Company periodically enters into credit risk participation agreements (RPAs) as a guarantor to other financial institutions, in order to mitigate those institutions’ credit risk associated with interest rate swaps with third parties. The RPA stipulates that, in the event of default by the third party on the interest rate swap, the Company will reimburse a portion of the loss borne by the financial institution. These interest rate swaps are normally collateralized (generally with real property, inventories and equipment) by the third party, which limits the credit risk associated with the Company’s RPAs. The third parties usually have other borrowing relationships with the Company. The Company monitors overall borrower collateral and at June 30, 2024, believes sufficient collateral is available to cover potential swap losses. The RPAs are carried at fair value throughout their term with all changes in fair value, including those due to a change in the third party’s creditworthiness, recorded in current earnings. The terms of the RPAs, which correspond to the terms of the underlying swaps, range from 2 years to 15 years. At June 30, 2024, the fair value of the Company's guarantee liabilities for RPAs was $83 thousand, and the notional amount of the underlying swaps was $455.7 million. The maximum potential future payment guaranteed by the Company cannot be readily estimated but is dependent upon the fair value of the interest rate swaps at the time of default.

6. Leases

The Company has net investments in direct financing and sales-type leases to commercial, industrial, and tax-exempt entities. These leases are included within business loans on the Company's consolidated balance sheets. The Company primarily leases various types of equipment, trucks and trailers, and office furniture and fixtures. Lease agreements may include options for the lessee to renew or purchase the leased equipment at the end of the lease term. The Company has elected to adopt the lease component expedient in which the lease and nonlease components are combined into the total lease receivable. The Company also leases office space to third parties, and these leases are classified as operating leases. The leases may include options to renew or expand the leased space, and currently the leases have remaining terms of 1 month to 14 years.

The following table provides the components of lease income.

8. Common Stock *

Presented below is a summary of the components used to calculate basic and diluted income per share. The Company applies the two-class method of computing income per share, as nonvested share-based awards that pay nonforfeitable common stock dividends are considered securities which participate in undistributed earnings with common stock. The two-class method requires the calculation of separate income per share amounts for the nonvested share-based awards and for common stock. Income per share attributable to common stock is shown in the table below. Nonvested share-based awards are further discussed in Note 13.

Unexercised stock appreciation rights of 411 thousand and 450 thousand for the three month periods ended June 30, 2024 and 2023, respectively, and 382 thousand and 277 thousand for the six month periods ended June 30, 2024 and 2023, respectively, were excluded from the computation of diluted income per common share because their inclusion would have been anti-dilutive.

In the Annual Meeting of the Shareholders, held on April 19, 2023, a proposal to increase the shares of the Company's common stock authorized for issuance under its articles of incorporation was approved. This approval increased the authorized shares from 140,000,000 to 190,000,000.

* All prior year share and per share amounts in this note have been restated for the 5% common stock dividend distributed in December 2023.

10. Segments

The Company segregates financial information for use in assessing its performance and allocating resources among three operating segments: Consumer, Commercial and Wealth. The Consumer segment consists of various consumer loan and deposit products offered through its retail branch network of approximately 140 locations.  This segment also includes indirect and other consumer loan financing businesses, along with debit and credit card loan and fee businesses.  The Commercial segment provides corporate lending (including the Small Business Banking product line within the branch network), leasing, and international services, along with business and governmental deposit products and commercial cash management services.  This segment also includes both merchant and commercial bank card products as well as the Commercial Tradable Products division, which sells fixed income securities, underwrites municipal bonds, and provides securities safekeeping and accounting services to its business and correspondent bank customers.  The Wealth segment provides traditional trust and estate planning, advisory and discretionary investment management, and brokerage services.  This segment also provides various loan and deposit related services to its private banking customers.

34

The following table presents selected financial information by segment and reconciliations of combined segment totals to consolidated totals. There were no material intersegment revenues between the three segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. If appropriate, these changes are reflected in prior year information presented below. Net interest income allocated among the segments prior to 2024 has been restated to reflect a funds transfer pricing methodology change implemented on January 1, 2024 for all deposit types, except certificates of deposit. The new methodology moves from a rolling pool to a profitability range methodology. The new methodology more accurately reflects the profitability of affected deposits relative to current rates and removes most interest rate risk from business segments.

The information presented above was derived from the internal profitability reporting system used by management to monitor and manage the financial performance of the Company. This information is based on internal management accounting procedures and methods, which have been developed to reflect the underlying economics of the businesses. The methodologies are applied in connection with funds transfer pricing and assignment of overhead costs among segments. Funds transfer pricing was used in the determination of net interest income by assigning a standard cost (credit) for funds used (provided by) assets and liabilities based on their maturity, prepayment and/or repricing characteristics.

The segment activity, as shown above, includes both direct and allocated items. Amounts in the “Other/Elimination” column include activity not related to the segments, such as that relating to administrative functions, the investment securities portfolio, and the effect of certain expense allocations to the segments. The provision for credit losses in this category contains the difference between net loan charge-offs assigned directly to the segments and the recorded provision for credit loss expense. Included in this category’s net interest income are earnings of the investment portfolio, which are not allocated to a segment. Additionally, in 2023, interest expense on the Company's brokered certificates of deposit was included in this column, as the Company's brokered certificates of deposit were not allocated to a segment. There were no brokered certificates of deposit in 2024.

35

The performance measurement of the operating segments is based on the management structure of the Company and is not necessarily comparable with similar information for any other financial institution. The information is also not necessarily indicative of the segments' financial condition and results of operations if they were independent entities.

11. Derivative Instruments

The notional amounts of the Company’s derivative instruments are shown in the table below. These contractual amounts, along with other terms of the derivative, are used to determine amounts to be exchanged between counterparties and are not a measure of loss exposure. The Company's derivatives are accounted for as freestanding derivatives, and with the exception of the interest rate floors, changes in their fair value are recorded in current earnings.

(In thousands)	June 30, 2024		December 31, 2023
Interest rate swaps	$	2,300,300	$	2,166,393
Interest rate floors	2,000,000		2,000,000
Interest rate caps	267,447		336,682
Credit risk participation agreements	676,506		653,887
Foreign exchange contracts	33,042		30,401
Mortgage loan commitments	7,252		3,004
Mortgage loan forward sale contracts	717		1,349
Forward TBA contracts	7,500		3,000
Total notional amount	$	5,292,764	$	5,194,716

The largest group of notional amounts relate to interest rate swap contracts sold to commercial customers who wish to modify their interest rate sensitivity. The customers are engaged in a variety of businesses, including real estate, manufacturing, retail product distribution, education, and retirement communities. These interest rate swap contracts with customers are offset by matching interest rate swap contracts purchased by the Company from other financial institutions (dealers). Contracts with dealers that require central clearing are novated to a clearing agency who becomes the Company's counterparty. Because of the matching terms of the offsetting contracts, in addition to collateral provisions which mitigate the impact of non-performance risk, changes in fair value subsequent to initial recognition have a minimal effect on earnings.

Many of the Company’s interest rate swap contracts with large financial institutions contain contingent features relating to debt ratings or capitalization levels. Under these provisions, if the Company’s debt rating falls below investment grade or if the Company ceases to be “well-capitalized” under risk-based capital guidelines, certain counterparties can require immediate and ongoing collateralization on interest rate swaps in net liability positions or instant settlement of the contracts. The Company maintains debt ratings and capital well above these minimum requirements.

As of June 30, 2024, the Company held four interest rate floors indexed to 1-month SOFR to hedge the risk of declining interest rates on certain floating rate commercial loans. The floors have a combined notional value of $2.0 billion and are forward-starting. Each of the four interest rate floors has a six-year term and a notional amount of $500.0 million. In the event that the index rate falls below zero, the maximum rate that the Company can earn on the notional amount of each floor is limited to the strike rate. Information about the floors is provided in the table below.

Strike Rate		Effective Date	Maturity Date
3.50	%	July 1, 2024	July 1, 2030
3.25	%	November 1, 2024	November 1, 2030
3.00	%	March 1, 2025	March 1, 2031
2.75	%	July 1, 2025	July 1, 2031

The premium paid for the floors totaled $90.2 million. The maximum length of time over which the Company is hedging its exposure to lower rates is approximately 7 years. These interest rate floors qualified and were designated as cash flow hedges and were assessed for effectiveness using regression analysis. The change in the fair value of these interest rate floors is recorded in AOCI, net of the amortization of the premiums paid, which are recorded against interest and fees on loans in the consolidated statements of income. As of June 30, 2024, net deferred losses on the interest rate floors totaled $25.8 million (pre-tax) and were recorded in AOCI in the consolidated balance sheet. As of June 30, 2024, it is expected that $10.7 million

36

(pre-tax) interest rate floor premium amortization will be reclassified from AOCI into earnings over the next 12 months for the outstanding interest rate floors.

During the year ended December 31, 2020, the Company monetized three interest rate floors that were previously classified as cash flow hedges with a combined notional balance of $1.5 billion and an asset fair value of $163.2 million. As of June 30, 2024, the total realized gains on the monetized cash flow hedges remaining in AOCI was $40.1 million (pre-tax), which will be reclassified into interest income over the next 2.5 years. The estimated amount of net gains related to the cash flow hedges remaining in AOCI at June 30, 2024 that is expected to be reclassified into income within the next 12 months is $21.2 million.

The Company also contracts with other financial institutions, as a guarantor or beneficiary, to share credit risk associated with certain interest rate swaps through risk participation agreements. The Company’s risks and responsibilities as guarantor are further discussed in Note 5 on Guarantees. In addition, the Company enters into foreign exchange contracts, which are mainly comprised of contracts with customers to purchase or deliver specific foreign currencies at specific future dates.

Under its program to sell residential mortgage loans in the secondary market, the Company designates certain newly-originated residential mortgage loans as held for sale. Derivative instruments arising from this activity include mortgage loan commitments and forward loan sale contracts. Changes in the fair values of the loan commitments and funded loans prior to sale that are due to changes in interest rates are economically hedged with forward contracts to sell residential mortgage-backed securities in the to-be-announced (TBA) market. These forward TBA contracts are also considered to be derivatives and are settled in cash at the security settlement date.

The fair values of the Company's derivative instruments, whose notional amounts are listed above, are shown in the table below. Information about the valuation methods used to determine fair value is provided in Note 15 on Fair Value Measurements.

The Company's policy is to present its derivative assets and derivative liabilities on a gross basis on its consolidated balance sheets, and these are reported in other assets and other liabilities. In prior years, certain collateral posted to and from the Company's clearing counterparty has been applied to the fair values of the cleared swap. There was no reduction to positive or negative fair values of cleared swaps at June 30, 2024 and December 31, 2023.

The Company made an election to exclude the initial premiums paid on the interest rate floors from the hedge effectiveness measurement. Those initial premiums are amortized over the periods between the premium payment month and the contract maturity month. The pre-tax effects of the gains and losses (both the included and excluded amounts for hedge effectiveness assessment) recognized in the other comprehensive income from the cash flow hedging instruments and the amounts reclassified from accumulated other comprehensive income into income (both included and excluded amounts for hedge effectiveness measurement) are shown in the table below.

The following table shows the extent to which assets and liabilities relating to derivative instruments have been offset in the consolidated balance sheets. It also provides information about these instruments which are subject to an enforceable master netting arrangement, irrespective of whether they are offset, and the extent to which the instruments could potentially be offset. Also shown is collateral received or pledged in the form of other financial instruments, which is generally cash or marketable securities. The collateral amounts in this table are limited to the outstanding balances of the related asset or liability (after netting is applied); thus, amounts of excess collateral are not shown. Most of the derivatives in the following table were transacted under master netting arrangements that contain a conditional right of offset, such as close-out netting, upon default.

38

While the Company is party to master netting arrangements with most of its swap derivative counterparties, the Company does not offset derivative assets and liabilities under these agreements on its consolidated balance sheets. Collateral exchanged between the Company and dealer bank counterparties is generally subject to thresholds and transfer minimums, and usually consists of marketable securities. By contract, these may be sold or re-pledged by the secured party until recalled at a subsequent valuation date by the pledging party. For those swap transactions requiring central clearing, the Company posts cash or securities to its clearing agent. Collateral positions are valued daily, and adjustments to amounts received and pledged by the Company are made as appropriate to maintain proper collateralization for these transactions. Swap derivative transactions with customers are generally secured by rights to non-financial collateral, such as real and personal property, which is not shown in the table below.

12. Resale and Repurchase Agreements

The Company regularly enters into resale and repurchase agreement transactions with other financial institutions and with its own customers. Resale and repurchase agreements are agreements to purchase/sell securities subject to an obligation to resell/repurchase the same or similar securities. They are accounted for as secured lending and collateralized borrowing (e.g. financing transactions), not as true sales and purchases of the underlying collateral securities. Some of the resale and repurchase agreements were transacted under master netting arrangements that contain a conditional right of offset, such as close-out netting, upon default. The security collateral accepted or pledged in resale and repurchase agreements with other financial institutions may be sold or re-pledged by the secured party, but is usually delivered to and held by third party trustees. The Company generally retains custody of securities pledged for repurchase agreements with its customers.

39

The following table shows the extent to which resale agreement assets and repurchase agreement liabilities with the same counterparty have been offset on the consolidated balance sheets, in addition to the extent to which they could potentially be offset. Also shown is collateral received or pledged, which consists of marketable securities. The collateral amounts in the table are limited to the outstanding balances of the related asset or liability (after offsetting is applied); thus amounts of excess collateral are not shown.

13. Stock-Based Compensation

The Company issues stock-based compensation in the form of nonvested restricted stock and stock appreciation rights (SARs). Historically, most of the awards have been issued during the first quarter of each year. The stock-based compensation expense charged against income was $4.2 million and $3.9 million in the three months ended June 30, 2024 and 2023 respectively, and $8.5 million and $8.3 million in the six months ended June 30, 2024 and 2023, respectively.

Nonvested stock awards granted generally vest in 4 to 7 years and contain restrictions as to transferability, sale, pledging, or assigning, among others, prior to the end of the vesting period. Dividend and voting rights are conferred upon grant. A summary of the status of the Company’s nonvested share awards as of June 30, 2024, and changes during the six month period then ended, is presented below.

	Shares	Weighted Average Grant Date Fair Value
Nonvested at January 1, 2024	1,166,335	$58.48
Granted	322,088	52.03
Vested	(250,127)	52.21
Forfeited	(27,582)	59.87
Nonvested at June 30, 2024	1,210,714	$58.03

SARs are granted with exercise prices equal to the market price of the Company’s stock at the date of grant. SARs vest ratably over 4 years of continuous service and have contractual terms of 10 years. All SARs must be settled in stock under provisions of the plan. In determining compensation cost, the Black-Scholes option-pricing model is used to estimate the fair value of SARs on date of grant. The current year per share average fair value and the model assumptions are shown in the table below.

Weighted per share average fair value at grant date	$14.88
Assumptions:
Dividend yield	2.1	%
Volatility	29.3	%
Risk-free interest rate	4.2	%

14. Revenue from Contracts with Customers

Revenue from contracts with customers, Accounting Standard Codification 606 ("ASC 606"), requires revenue recognition for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For the six months ended June 30, 2024, approximately 63% of the Company’s total revenue was comprised of net interest income, which is not within the scope of this guidance. Of the remaining revenue, those items that were subject to this guidance mainly included fees for bank card, trust, deposit account services and consumer brokerage services.

The following table disaggregates revenue from contracts with customers by major product line.

	Three Months Ended June 30				Six Months Ended June 30
(In thousands)	2024		2023		2024		2023
Trust fees	$	52,291	$	47,265	$	103,396	$	92,593
Bank card transaction fees	47,477		49,725		94,407		96,379
Deposit account charges and other fees	25,325		22,633		49,476		44,385
Consumer brokerage services	4,478		4,677		8,886		9,762
Other non-interest income	12,325		9,486		22,841		17,825
Total non-interest income from contracts with customers	141,896		133,786		279,006		260,944
Other non-interest income (1)	10,348		13,819		22,086		24,273
Total non-interest income	$	152,244	$	147,605	$	301,092	$	285,217

(1) This revenue is not within the scope of ASC 606, and includes fees relating to bond trading activities, loan fees and sales, derivative instruments, standby letters of credit and various other transactions.

For bank card transaction fees, nearly all of debit and credit card fees are earned in the Consumer segment, while corporate card and merchant fees are earned in the Commercial segment. The Consumer and Commercial segments contributed approximately 31% and 69%, respectively, of the Company's deposit account charge revenue. All trust fees and nearly all consumer brokerage services income were earned in the Wealth segment.    

The following table presents the opening and closing receivable balances for the six month periods ended June 30, 2024 and 2023 for the Company’s significant revenue from contracts with customers.

(In thousands)	June 30, 2024		December 31, 2023		June 30, 2023		December 31, 2022
Bank card transaction fees	$	15,824	$	18,069	$	16,321	$	17,254
Trust fees	2,174		1,764		1,984		2,038
Deposit account charges and other fees	7,366		6,588		6,488		6,631
Consumer brokerage services	—		8		637		949

For these revenue categories, none of the transaction price has been allocated to performance obligations that are unsatisfied as of the end of a reporting period.

15. Fair Value Measurements

The Company uses fair value measurements to record fair value adjustments to certain financial and nonfinancial assets and liabilities and to determine fair value disclosures. Various financial instruments such as available for sale debt securities, equity securities, trading debt securities, certain investments relating to private equity activities, and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets and liabilities on a nonrecurring basis, such as mortgage servicing rights and certain other investment securities. These nonrecurring fair value adjustments typically involve lower of cost or fair value accounting or write-downs of individual assets.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value. For accounting disclosure purposes, a three-level valuation hierarchy of fair value measurements has been established. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

•Level 1 – inputs to the valuation methodology are quoted prices for identical assets or liabilities in active markets.

•Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and inputs that are observable for the assets or liabilities, either directly or indirectly (such as interest rates, yield curves, and prepayment speeds).

•Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value. These may be internally developed, using the Company’s best information and assumptions that a market participant would consider.

The valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis are described in the Fair Value Measurements note in the Company's 2023 Annual Report on Form 10-K. There have been no significant changes in these methodologies since then.

16. Fair Value of Financial Instruments

The carrying amounts and estimated fair values of financial instruments held by the Company are set forth below. Fair value estimates are made at a specific point in time based on relevant market information. They do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for many of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, risk characteristics and economic conditions.

Item 2.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes and with the statistical information and financial data appearing in this report as well as the Company's 2023 Annual Report on Form 10-K. Results of operations for the three and six months ended June 30, 2024 are not necessarily indicative of results to be attained for any other period.

Forward-Looking Information

This report may contain "forward-looking statements" that are subject to risks and uncertainties and include information about possible or assumed future results of operations. Many possible events or factors could affect the future financial results and performance of the Company. This could cause results or performance to differ materially from those expressed in the forward-looking statements. Words such as "expects", "anticipates", "believes", "estimates", variations of such words and other similar expressions are intended to identify such forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in, or implied by, such forward-looking statements. Readers should not rely solely on the forward-looking statements and should consider all uncertainties and risks discussed throughout this report. Forward-looking statements speak only as of the date they are made. The Company does not undertake to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made or to reflect the occurrence of unanticipated events. Such possible events or factors include: changes in economic conditions in the Company's market area, changes in policies by regulatory agencies, governmental legislation and regulation, fluctuations in interest rates, changes in liquidity requirements, demand for loans in the Company's market area, changes in accounting and tax principles, estimates made on income taxes, competition with other entities that offer financial services, cybersecurity threats, and such other factors as discussed in Part I Item 1A - "Risk Factors" and Part II Item 7 - "Management's Discussion and Analysis of Financial Condition and Results of Operations" in the Company's 2023 Annual Report on Form 10-K. During the quarter ended June 30, 2024, there were no material changes to the Risk Factors disclosed in the Company's 2023 Annual Report on Form 10-K.

Critical Accounting Estimates and Related Policies

The Company has identified certain policies as being critical because they require management to make particularly difficult, subjective and/or complex judgments about matters that are inherently uncertain and because of the likelihood that materially different amounts would be reported under different conditions or using different assumptions. These estimates and related policies are the Company's allowance for credit losses and fair value measurement policies. A discussion of these estimates and related policies can be found in the sections captioned "Critical Accounting Policies" and "Allowance for Credit Losses on Loans and Liability for Unfunded Lending Commitments" in Management's Discussion and Analysis of Financial Condition and Results of Operations included in the Company's 2023 Annual Report on Form 10-K. There have been no changes in the Company's application of critical accounting policies since December 31, 2023.

(2) Revenue includes net interest income and non-interest income.

(3) The efficiency ratio is calculated as non-interest expense (excluding intangibles amortization) as a percent of revenue.

(4) The tangible common equity to tangible assets ratio is a measurement which management believes is a useful indicator of capital adequacy and utilization.

It provides a meaningful basis for period to period and company to company comparisons, and also assists regulators, investors and analysts in analyzing the financial position of the Company. Tangible common equity and tangible assets are non-GAAP measures and should not be viewed as substitutes for, or superior to, data prepared in accordance with GAAP.

For the quarter ended June 30, 2024, net income attributable to Commerce Bancshares, Inc. (net income) amounted to $139.6 million, an increase of $11.8 million, or 9.2%, compared to the second quarter of the previous year. For the current quarter, the annualized return on average assets was 1.86%, the annualized return on average equity was 18.52%, and the efficiency ratio was 55.95%. Diluted earnings per common share was $1.07 per share in the current quarter, an increase of 10.3% compared to $.97 per share in the second quarter of 2023, and increased 24.4% compared to $.86 per share in the previous quarter.

Compared to the second quarter of last year, net interest income increased $12.7 million, or 5.1%, mainly due to an increase in interest income on loans of $26.1 million and a $21.7 million decrease in interest expense on borrowings. This increase was partly offset by an increase of $29.7 million in interest expense on deposits. The provision for credit losses decreased $1.0 million, or 15.5%, compared to the same quarter in the prior year. Non-interest income increased $4.6 million, or 3.1%, compared to the second quarter of 2023, mainly due to an increase in trust fees, capital market fees, and deposit account fees, partly offset by lower letter of credit fees. Net gains on investment securities totaled $3.2 million in the current quarter compared to net gains of $3.4 million in the same quarter of last year. Securities gains in the current quarter primarily resulted from net gains of $178.2 million on equity investments and net gains in fair value of $5.7 million recorded on private equity investments. These gains were largely offset by net losses of $179.1 million on sales of available for sale debt securities. Non-interest expense increased $4.6 million, or 2.0%, over the second quarter of 2023, mainly due to increases in salaries expense and data processing and software expense, partly offset by lower deposit insurance expense and lower marketing expense.

Net income for the first six months of 2024 was $252.2 million, an increase of $5.0 million, or 2.0%, from the same period last year. Diluted earnings per common share was $1.93, an increase of 2.7% compared to $1.88 per share in the same period last year. For the first six months of 2024, the annualized return on average assets was 1.67%, the annualized return on average equity was 16.98%, and the efficiency ratio was 58.75%. Net interest income increased $10.1 million, or 2.0%, over the same period last year. This growth was largely due to an increase of $67.0 million in interest income on loans, an increase of $16.5 million in interest earned on deposits with banks, and a $24.8 million decrease in interest expense on borrowings, largely offset by a $85.3 million increase in interest expense on deposits. The provision for credit losses was $10.3 million for the first six months of 2024, compared to a provision of $17.9 million in the same period last year. Non-interest income increased $15.9 million, or 5.6%, from the first six months of last year mainly due to higher trust and deposit account fees. Non-interest expense increased $26.2 million, or 5.8%, over the first six months of last year mainly due to increases in salaries and data processing and software expense and higher litigation settlement expense.

Net interest income in the second quarter of 2024 was $262.2 million, an increase of $12.7 million over the second quarter of 2023. On a fully taxable-equivalent (FTE) basis, net interest income totaled $264.6 million in the second quarter of 2024, up $12.8 million over the same period last year and up $13.3 million over the previous quarter. The increase in net interest income

53

compared to the second quarter of 2023 was mainly due to higher interest income earned on loans (FTE) of $26.5 million and lower interest expense on borrowings of $21.7 million, partly offset by higher deposit interest expense of $29.7 million. The increase in total interest earned on loans (FTE) was the result of higher loan yields on all loan products, especially commercial loans, many of which have variable rates, coupled with higher average balances. Interest expense on borrowings decreased mainly due to lower average balances, while the increase in deposit interest expense was due to higher average rates paid. The Company's net yield on earning assets (FTE) was 3.55% in the current quarter compared to 3.12% in the second quarter of 2023.

Total interest income (FTE) increased $20.8 million over the second quarter of 2023. Interest income on loans (FTE) was $269.2 million during the second quarter of 2024, an increase of $26.5 million, or 10.9%, over the same quarter last year. The increase in interest income over the same quarter of last year was primarily due to an increase of 46 basis points in the average rate earned and growth of $505.4 million, or 3.0%, in average loan balances. Most of the increase in interest income occurred in the business, business real estate and consumer loan categories. The largest increase to interest income occurred in business loan interest, which grew $10.7 million due to a 53 basis point increase in the average rate earned, coupled with growth in average balances of $223.0 million, or 3.9%. Business real estate loan interest income increased $4.5 million due to an increase of 30 basis points in the average rate earned and higher average balances of $125.2 million, or 3.5%. Consumer loan interest income grew $5.2 million due to a 93 basis point increase in the average rate earned. In addition, construction and land loan interest income increased $1.9 million due to an increase of 44 basis points in the average rate earned and higher average loan balances of $21.3 million, or 1.5%. Personal real estate loan interest income grew $3.5 million due to a 36 basis point increase in the average rate earned and growth of $84.0 million, or 2.8%, in average loan balances.

Interest income on investment securities (FTE) was $71.4 million during the second quarter of 2024, which was a decrease of $3.2 million from the same quarter last year. The decrease in interest income occurred mainly in interest earned on mortgage-backed securities and asset-backed securities. Interest income earned on mortgage-backed securities declined $4.1 million due to a $762.6 million, or 12.1%, decrease in average balances. In addition, the Company recorded a $740 thousand adjustment to premium amortization at June 30, 2024, which increased income and reflected slower forward prepayment speed estimates on mortgage-backed securities. The adjustment this quarter was lower than the $1.7 million in the same quarter last year. Interest income earned on asset-backed securities declined $3.6 million due to lower average balances of $1.0 billion, or 36.9%, partly offset by a 42 basis point increase in the average rate earned. Interest income earned on state and municipal obligations declined $2.5 million due to a $462.6 million, or 30.2%, decrease in average balances. These decreases to interest income were partly offset by growth in interest income on U.S. government and federal agency obligations of $6.2 million, driven by a 162 basis point increase in the average rate earned and higher average balances of $166.3 million. Interest income related to the Company's U.S. Treasury inflation-protected securities, which is tied to the non-seasonally adjusted Consumer Price Index (CPI-U), increased $1.2 million over the same quarter last year. Additionally, the average rate earned on investment securities during the three months ended June 30, 2024 increased 38 basis points over the same period in the prior year. The average balance of the total investment portfolio (excluding unrealized fair value adjustments on available for sale debt securities) was $10.4 billion in the second quarter of 2024, compared to $12.6 billion in the second quarter of 2023.

Interest income on securities purchased under agreements to resell decreased $1.7 million from the same quarter last year, due to a decline of $521.4 million in the average balance, partly offset by an increase of 122 basis points in the average rate earned. Interest income on balances at the Federal Reserve decreased $624 thousand due to a decrease of $184.4 million in the average balance invested, partly offset by an increase of 34 basis points in the average rate earned.

The average fully taxable-equivalent yield on total interest earning assets was 4.98% in the second quarter of 2024, up from 4.34% in the second quarter of 2023.

Total interest expense increased $8.0 million compared to the second quarter of 2023 due to an increase of $29.7 million in interest expense on interest bearing deposits, partly offset by a $21.7 million decrease in interest expense on borrowings. The increase in deposit interest expense resulted mainly from an increase of $26.8 million in interest expense on interest checking and money market deposit accounts due to an 80 basis point increase in the average rate paid and an increase of $243.7 million in average balances. In addition, interest expense on certificates of deposit increased $2.9 million mainly due to an increase of 55 basis points in the average rate paid. The overall rate paid on total deposits increased 70 basis points over the same quarter last year. Interest expense on other borrowings decreased $21.1 million due to a decrease of $1.6 billion in average Federal Home Loan Bank (FHLB) borrowings. In addition, interest expense on federal funds purchased decreased $2.8 million mainly due to a $242.1 million decrease in the average balance, while interest expense on customer repurchase agreements increased $2.3 million mainly due to a 35 basis point increase in the average rate paid. The overall average rate incurred on all interest bearing liabilities was 2.21% and 1.87% in the second quarters of 2024 and 2023, respectively.

Net interest income (FTE) for the first six months of 2024 was $515.9 million compared to $505.2 million for the same period in 2023. For the first six months of 2024, the net interest margin was 3.44% compared to 3.18% for the same period in 2023.

Total interest income (FTE) for the first six months of 2024 increased $70.4 million over the same period last year mainly due to higher interest income on loans (FTE) and balances at the Federal Reserve, partly offset by lower interest income on investment securities (FTE). Loan interest income (FTE) increased $67.7 million, or 14.5%, due to a 59 basis point increase in the average rate earned and a $590.1 million, or 3.6%, increase in average loan balances. Most of the increase occurred in the business, business real estate and consumer loan categories, but interest income in all loan categories increased due to higher average rates earned and average loan balances. Interest income on investment securities (FTE) decreased $9.0 million due to a $2.3 billion decrease in average balances, partly offset by a 32 basis point increase in the average rate earned. Interest earned on asset-backed and mortgage-backed securities decreased $7.2 million and $4.9 million, respectively, due to lower average balances, partly offset by increases in the average rate earned. Interest earned on state and municipal obligations decreased $6.0 million due to declines in both the average balance and the average rate earned. These decreases in interest income on investment securities were partly offset by an increase in interest earned on U.S. government and federal agency obligations of $5.5 million, mainly due to an increase in the average rate earned. Interest income on securities purchased under agreements to resell decreased $4.0 million due to lower average balances, partly offset by higher average rates earned. Interest income on balances at the Federal Reserve increased $16.5 million due to higher average balances and average rates earned.

Total interest expense for the first six months of 2024 increased $59.7 million compared to the same period last year. Interest expense on deposits increased $85.3 million, due to a 97 basis point increase in the average rate paid and a $493.6 million increase in average balances. Interest expense on borrowings decreased $25.6 million, mainly due lower FHLB borrowings of $1.1 billion. In addition, interest expense on federal funds purchased declined mainly due to lower average balances, while interest expense on customer repurchase agreements increased due to higher average rates and average balances. The overall cost of total interest bearing liabilities increased to 2.21% compared to 1.55% in the same period last year.

For the second quarter of 2024, total non-interest income amounted to $152.2 million compared to $147.6 million in the same quarter last year, which was an increase of $4.6 million, or 3.1%. The increase was mainly due to higher trust fees, deposit account fees and capital market fees, partly offset by lower net bank card fees and letter of credit fees. Trust fees increased $5.0 million, or 10.6%, mainly due to growth of $4.8 million in private client trust fees. Bank card transaction fees for the current quarter declined $2.2 million, or 4.5%, from the same period last year, mainly due to lower net corporate card fees, partly offset by growth in net merchant fees. The decline in net corporate card fees of $3.0 million was mainly due to lower interchange fees and higher rewards expense. Net merchant fees increased $506 thousand mainly due to higher interchange fees, partly offset by higher network expense. Compared to the second quarter of last year, deposit account fees increased $2.7 million, or 11.9%, mainly due to higher corporate cash management fees of $2.4 million. Consumer brokerage fees declined $199 thousand, while capital market fees increased $1.8 million, or 61.6%, mainly due to higher underwriting fees. Other non-interest income decreased $3.1 million, or 17.8%, mainly due to decreases of $2.3 million in letter of credit fees and $919 thousand in swap fees.

Non-interest income for the first six months of 2024 was $301.1 million compared to $285.2 million in the first six months of 2023, which was an increase of $15.9 million, or 5.6%. The increase was mainly due to higher trust fees, deposit account fees and capital market fees, partly offset by lower net bank card fees. Trust fees increased $10.8 million, or 11.7%, mainly due to higher private client and institutional trust fees. Bank card transaction fees for the current year declined $2.0 million, or 2.0%, from the same period last year, mainly due to a decrease of $2.9 million in net corporate card fees, partly offset by an increase in net merchant fees of $402 thousand. Deposit account fees increased $5.1 million, or 11.5%, mainly due to higher corporate cash management fees and overdraft and return item fees. Capital market fees increased $2.3 million, or 37.2%, mainly due to higher underwriting fees, while loan fees and sales increased $1.2 million mainly due to higher loan commitment fees and mortgage banking revenue. Other non-interest income decreased $764 thousand, or 2.5%, mainly due to decreases of $2.2 million in letter of credit fees and $1.4 million in swap fees. These decreases were partly offset by higher tax credit sales income of $1.9 million and cash sweep commissions of $1.3 million.

Net gains on investment securities, which were recognized in earnings during the three months ended June 30, 2024 and 2023, are shown in the table above. Net securities gains of $3.2 million were reported in the second quarter of 2024, compared to net gains of $3.4 million in the same period last year. The net gains in the second quarter of 2024 were mainly comprised of net gains of $178.2 million on equity investments and net gains in fair value of $5.7 million recorded on private equity investments. These gains were largely offset by net losses of $179.1 million on sales of available for sale debt securities. The net gains on investment securities for the same quarter last year were primarily comprised of $9.1 million of net gains in fair value on the Company’s private equity investments, partially offset by losses of $5.4 million on the sale of available for sale securities.

Net gains on investment securities of $3.0 million were recognized in earnings for the six months ended June 30, 2024, compared to net gains of $3.1 million for the same period in 2023. Net gains in the first half of 2024 were mainly comprised of net gains of $178.3 million on equity investments and net gains in fair value of $12.8 million recorded on private equity investments, largely offset by net losses of $187.5 million on sales of available for sale securities. Net gains in the first half of 2023 were mainly comprised of net gains in fair value of $11.3 million on private equity investments, due to fair value adjustments, partially offset by losses of $8.4 million on sales of available for sale debt securities. The portion of private equity activity attributable to minority interests is reported as non-controlling interest in the consolidated statements of income and resulted in expense of $1.8 million during the first six months of 2024 and expense of $2.5 million during the first six months of 2023.

The Company's significant gains in equity securities for the three and six months ended June 30, 2024 primarily relate to gains recorded on its shares of Visa, as described in Note 3, Investment Securities. Likewise, the $179.1 million losses realized on the Company's available for sale debt securities portfolio relate to the successful execution of its planned available for sale debt security portfolio repositioning, in which the Company sold bonds with an amortized cost of $1.2 billion and subsequently reinvested the proceeds into higher yielding available for sale debt securities. Additional information about the Company's available for sale debt portfolio repositioning transactions is discussed in Note 3, Investment Securities.

Non-interest expense for the second quarter of 2024 amounted to $232.2 million, an increase of $4.6 million, or 2.0%, compared to expense of $227.6 million in the second quarter of last year. The increase in expense over the same period last year was mainly due to higher salaries expense, data processing and software expense and other non-interest expense, partly offset by lower marketing and deposit insurance expense. Salaries and employees benefits expense increased $3.7 million, or 2.5%, mainly due to higher full-time salaries expense of $3.8 million and other salaries expense of $1.0 million, partly offset by lower healthcare expense of $1.5 million.

Data processing and software expense increased $2.8 million, or 9.8%, mainly due to increased costs for service providers. Occupancy expense decreased $451 thousand, or 3.5%, while marketing expense declined $1.0 million, or 15.9%. Deposit insurance expense decreased $1.8 million partly due to a $1.2 million accrual adjustment in the current quarter to the special assessment by the FDIC to replenish the Deposit Insurance Fund. Other non-interest expense increased $1.2 million, or 5.7%, mainly due to a $5.0 million donation to a related charitable foundation, partly offset by deconversion expense of $2.1 million recorded in the same period last year.

Non-interest expense amounted to $477.9 million for the first six months of 2024, an increase of $26.2 million, or 5.8%, over the first six months of 2023. Salaries and benefits expense increased $11.1 million, or 3.8%, mainly due to higher full-time salaries expense, other salaries expense and payroll taxes, partly offset by a decrease in healthcare expense. Data processing and software expense increased $5.8 million, or 10.2%, due to increased costs for service providers and higher bank card processing fees. Occupancy expense increased $364 thousand, or 1.4%, while equipment expense increased $387 thousand, or 4.0%, due to higher depreciation and service contract expense. Marketing expense decreased $2.4 million, or 20.7%, while deposit insurance increased $1.5 million, or 17.5%, due to accrual adjustments in 2024 to the special assessment by the FDIC. Other non-interest expense increased $9.3 million, or 23.3%, mainly due to litigation settlement expense of $10.0 million, net of insurance, and the charitable donation of $5.0 million, partly offset by deconversion expense of $2.1 million recorded in 2023.

To determine the amount of the allowance for credit losses on loans and the liability for unfunded lending commitments, the Company has an established process which assesses the risks and losses expected in its portfolios. This process provides an allowance based on estimates of allowances for pools of loans and unfunded lending commitments, as well as a second, smaller component based on certain individually evaluated loans and unfunded lending commitments. The Company's policies and processes for determining the allowance for credit losses on loans and the liability for unfunded lending commitments are discussed in Note 1 to the consolidated financial statements and in the "Allowance for Credit Losses" discussion within Critical Accounting Estimates and Related Policies in Item 7 of the 2023 Annual Report on Form 10-K.

Net loan charge-offs in the second quarter of 2024 amounted to $9.8 million, compared to $8.9 million in the prior quarter and $6.5 million in the second quarter of last year. Compared to the same period last year, total net loan charge-offs in the second quarter of 2024 increased $3.3 million and increased $880 thousand from the previous quarter. The increase over the prior year was mainly driven by increases in net charge-offs on consumer credit card, consumer and business loans of $2.1 million, $531 thousand, and $457 thousand, respectively. The increase from the previous quarter was driven by the increase in net charge-offs on consumer credit card and business loans.

For the three months ended June 30, 2024, annualized net charge-offs on average consumer credit card loans were 4.91%, compared to 4.60% in the previous quarter and 3.38% in the same period last year. Consumer loan annualized net charge-offs in the current quarter amounted to .34%, compared to .38% in the prior quarter and .24% in the same period last year. In the second quarter of 2024, total annualized net loan charge-offs were .23%, compared to .21% in the previous quarter and .16% in the same period last year.

For the three months ended June 30, 2024, the provision for credit losses on loans was $7.8 million which was a $2.0 million increase over the $5.9 million provision recorded in the same period last year and a $902 thousand increase over the $6.9 million provision recorded at March 31, 2024. The increase in the provision for credit losses on loans during the second quarter of 2024 over the same period last year was due to higher net loan charge-offs during the second quarter of 2024, partly offset by a larger reduction in the allowance for credit losses on loans in the current quarter compared to the same period last year.

For the six months ended June 30, 2024, net loan charge-offs amounted to $18.6 million, which was a $5.4 million increase over the first six months of 2023. The increase in net charge-offs on loans during the first six months of 2024 was primarily driven by an increase in net charge-offs on consumer credit card and consumer loans. For the six months ended June 30, 2024, annualized net loan charge-offs on consumer credit card and consumer loans were 4.75% and .36%, respectively, compared to 3.27% and .25%, respectively, for the same period last year. The annualized net charge-offs on loans for the six months ended June 30, 2024 and 2023, respectively, were .22% and .16%.

For the six months ended June 30, 2024, the provision for credit losses on loans was $14.8 million, which was a $7.0 million decrease from the $21.8 million provision recorded in the same period last year. Changes in the provision are driven by changes in the estimate for the allowance for credit losses on loans. The decrease in the provision for credit losses on loans in the first half of 2024 compared to the same period last year was primarily due to a reduction of the allowance for credit losses on loans during 2024, caused in part by an improving economic forecast in 2024, whereas the allowance for credit losses on

60

loans in the first half of 2023 was increasing due to a weakening economic forecast which included a mild recession. The decrease in the provision for credit losses on loans during the first half of 2024 compared to the same period in the prior year was partly offset by higher net charge-offs recorded in the six months ended June 30, 2024 compared to the first half of 2023.

For the six months ended June 30, 2024, the allowance for credit losses on loans decreased by $3.8 million, compared to the allowance for credit losses on loans at December 31, 2023. During the six months ended June 30, 2024, the allowance for credit losses on commercial loans decreased by $984 thousand, while the allowance for credit losses related to personal banking loans, including consumer credit card loans, decreased $2.9 million. The decrease in the allowance for credit losses on loans during the first half of 2024 was primarily the result of a slightly more optimistic economic forecast at June 30, 2024, coupled with a faster prepayment speed assumption in the personal real estate portfolio compared to the assumptions used at December 31, 2023. The allowance for credit losses on loans was $158.6 million at June 30, 2024 and was .92%, .94% and .94% of total loans at June 30, 2024, December 31, 2023 and June 30, 2023, respectively.

In the current quarter, the provision for credit losses on unfunded lending commitments was a benefit of $2.4 million, compared to a provision of $607 thousand for the three months ended June 30, 2023. For the six months ended June 30, 2024, the provision for credit losses on unfunded commitments was a benefit of $4.5 million compared to a benefit of $3.9 million in the first six months of 2023. At June 30, 2024, the liability for unfunded lending commitments was $20.7 million, compared to $25.2 million at December 31, 2023 and $29.2 million at June 30, 2023. The liability decreased primarily due to decreases in unfunded lending commitment balances, coupled with improvement in loss rate assumptions for the Company's construction loans. The Company's unfunded lending commitments primarily relate to construction loans, and the Company's estimate for credit losses in its unfunded lending commitments utilizes the same model and forecast as its estimate for credit losses on loans. See Note 2 for further discussion of the model inputs utilized in the Company's estimate of credit losses.

The Company considers the allowance for credit losses on loans and the liability for unfunded commitments adequate to cover losses expected in the loan portfolio, including unfunded commitments, at June 30, 2024.

The allowance for credit losses on loans and the liability for unfunded lending commitments are estimates that require significant judgment including projections of the macro-economic environment. The Company utilizes a third-party macro-economic forecast that continuously changes due to economic conditions and events. These changes in the forecast cause fluctuations in the allowance for credit losses on loans and the liability for unfunded lending commitments. The Company uses judgment to assess the macro-economic forecast and internal loss data in estimating the allowance for credit losses on loans and the liability for unfunded lending commitments. These estimates are subject to periodic refinement based on changes in the underlying external and internal data.

Risk Elements of Loan Portfolio

The following table presents non-performing assets and loans which are past due 90 days and still accruing interest. Non-performing assets include non-accruing loans and foreclosed real estate. Loans are placed on non-accrual status when management does not expect to collect payments consistent with acceptable and agreed upon terms of repayment. Loans that are 90 days past due as to principal and/or interest payments are generally placed on non-accrual, unless they are both well-secured and in the process of collection, or they are personal banking loans that are exempt under regulatory rules from being classified as non-accrual.

(Dollars in thousands)	June 30, 2024			December 31, 2023
Non-accrual loans	$	19,303		$	7,312
Foreclosed real estate	143			270

Non-performing assets as a percentage of total assets	.06		%	.02		%
Total loans past due 90 days and still accruing interest	$	18,566		$	21,864

Non-accrual loans totaled $19.3 million at June 30, 2024, an increase of $12.0 million from the balance at December 31, 2023. The increase occurred mainly in business real estate non-accrual loans, which increased $15.0 million. The increase was partly offset by a $3.1 million decrease in business non-accrual loans. At June 30, 2024, non-accrual loans were comprised of business real estate (78.0%), revolving home equity (10.2%), personal real estate (9.2%), and business (2.6%) loans. Foreclosed real estate totaled $143 thousand at June 30, 2024, a decrease of $127 thousand compared to December 31, 2023. Total loans past due 90 days or more and still accruing interest were $18.6 million as of June 30, 2024, a decrease of $3.3 million from

61

December 31, 2023. Balances by class for non-accrual loans and loans past due 90 days and still accruing interest are shown in the "Delinquent and non-accrual loans" section in Note 2 to the consolidated financial statements.

In addition to the non-performing and past due loans mentioned above, the Company also has identified loans for which management has concerns about the ability of the borrowers to meet existing repayment terms. They are classified as substandard under the Company's internal rating system. The loans are generally secured by either real estate or other borrower assets, reducing the potential for loss should they become non-performing. Although these loans are generally identified as potential problem loans, they may never become non-performing. Such loans totaled $242.2 million at June 30, 2024 compared with $216.4 million at December 31, 2023, resulting in an increase of $25.8 million, or 11.9%.

When borrowers are experiencing financial difficulty, the Company may agree to modify the contractual terms of a loan to a borrower in order to assist the borrower in repaying principal and interest owed to the Company. At June 30, 2024, the Company held $84.7 million of loans that had been modified during the six months ended June 30, 2024. These loans are further discussed in the "Modifications for borrowers experiencing financial difficulty" section in Note 2 to the consolidated financial statements.

Loans with Special Risk Characteristics

Management relies primarily on an internal risk rating system, in addition to delinquency status, to assess risk in the loan portfolio, and these statistics are presented in Note 2 to the consolidated financial statements. However, certain types of loans are considered at high risk of loss due to their terms, location, or special conditions. Additional information about the major types of loans in these categories and their risk features are provided below. Information based on loan-to-value (LTV) ratios was generally calculated with valuations at loan origination date. The Company normally obtains an updated appraisal or valuation at the time a loan is renewed or modified, or if the loan becomes significantly delinquent or is in the process of being foreclosed upon.

Real Estate – Construction and Land Loans

The Company's portfolio of construction and land loans, as shown in the table below, amounted to 8.1% of total loans outstanding at June 30, 2024. The largest component of construction and land loans was commercial construction, which decreased $65.2 million during the six months ended June 30, 2024. At June 30, 2024, multi-family residential construction loans totaled approximately $469.2 million, or 40.5%, of the commercial construction loan portfolio, compared to $414.6 million, or 33.9%, at December 31, 2023.

Real Estate – Business Loans

Total business real estate loans were $3.6 billion at June 30, 2024 and comprised 20.8% of the Company's total loan portfolio. These loans include properties such as manufacturing and warehouse buildings, small office and medical buildings, churches, hotels and motels, shopping centers, and other commercial properties. At June 30, 2024, 33.1% of business real estate loans were for owner-occupied real estate properties, which have historically resulted in lower net charge-off rates than non-owner-occupied commercial real estate loans.

Revolving Home Equity Loans

The Company had $331.4 million in revolving home equity loans at June 30, 2024 that were collateralized by residential real estate. Most of these loans (92.1%) are written with terms requiring interest-only monthly payments. These loans are offered in three main product lines: LTV up to 80%, 80% to 90%, and 90% to 100%. As of June 30, 2024, the outstanding

63

principal of loans with an original LTV higher than 80% was $29.9 million, or 9.0% of the portfolio, compared to $32.3 million as of December 31, 2023. Total revolving home equity loan balances over 30 days past due were $4.9 million at June 30, 2024 and $4.4 million at December 31, 2023, and the outstanding balance of revolving home equity loans on non-accrual status was $2.0 million at both June 30, 2024 and December 31, 2023. The weighted average FICO score for the total portfolio balance at June 30, 2024 is 785. At maturity, the accounts are re-underwritten, and if they qualify under the Company's credit, collateral and capacity policies, the borrower is given the option to renew the line of credit or convert the outstanding balance to an amortizing loan.  If criteria are not met, amortization is required, or the borrower may pay off the loan. During the remainder of 2024 through 2026, approximately 16% of the Company's current outstanding balances are expected to mature. Of these balances, approximately 84% have a FICO score of 700 or higher. The Company does not expect a significant increase in losses as these loans mature, due to their high FICO scores, low LTVs, and low historical loss levels.

Consumer Loans

Within the consumer loan portfolio are several direct and indirect product lines, which include loans for the purchase of automobiles, motorcycles, marine and RVs. Auto loans comprised 38.6% of the consumer loan portfolio at June 30, 2024, and outstanding balances for auto loans were $827.6 million and $820.3 million at June 30, 2024 and December 31, 2023, respectively. The balances over 30 days past due amounted to $9.9 million at June 30, 2024 and $9.5 million at December 31, 2023, respectively, and comprised 1.2% of the outstanding balances of these loans at both June 30, 2024 and December 31, 2023. For the six months ended June 30, 2024, $196.4 million of new auto loans were originated, compared to $210.1 million during the first six months of 2023.  At June 30, 2024, the automobile loan portfolio had a weighted average FICO score of 757, and net charge-offs on auto loans were .4% of average auto loans.

The Company's consumer loan portfolio also includes fixed rate home equity loans, typically for home repair or remodeling, and these loans comprised 10.7% of the consumer loan portfolio at June 30, 2024. Losses on these loans have historically been low, and the Company saw net recoveries of $62 thousand for the first six months of 2024. Private banking loans comprised 34.2% of the consumer loan portfolio at June 30, 2024. The Company's private banking loans are generally well-collateralized, and at June 30, 2024 were secured primarily by assets held by the Company's trust department. The remaining portion of the Company's consumer loan portfolio is comprised of health services financing, motorcycles, marine and RV loans. Net charge-offs on private banking, health services financing, motorcycle and marine and RV loans totaled $2.1 million in the first six months of 2024 and were .4% of the average balances of these loans at June 30, 2024.

Consumer Credit Card Loans

The Company offers low promotional rates on selected consumer credit card products. Out of a portfolio at June 30, 2024 of $566.9 million in consumer credit card loans outstanding, approximately $112.3 million, or 19.8%, carried a low promotional rate. Within the next six months, $50.0 million of these loans are scheduled to convert to the ongoing higher contractual rate. To mitigate some of the risk involved with this credit card product, the Company performs credit checks and detailed analysis of the customer borrowing profile before approving the loan application. Management believes that the risks in the consumer loan portfolio are reasonable and the anticipated loss ratios are within acceptable parameters.

Oil and Gas Energy Lending

The Company's energy lending portfolio is comprised of lending to the petroleum and natural gas sectors and totaled $268.8 million, or 1.6% of total loans at June 30, 2024, a decrease of $3.2 million from December 31, 2023, as shown in the table below.

(In thousands)	June 30, 2024		December 31, 2023		Unfunded commitments at June 30, 2024

Shared National Credits

The Company participates in credits of large, publicly traded companies which are defined by regulation as shared national credits, or SNCs. Regulations define SNCs as loans exceeding $100 million that are shared by three or more financial institutions. The Company typically participates in these loans when business operations are maintained in the local

64

communities or regional markets and opportunities to provide other banking services are present. The balance of SNC loans totaled $1.6 billion and $1.5 billion at June 30, 2024 and December 31, 2023, respectively. Additional unfunded commitments at June 30, 2024 totaled $2.4 billion.

Income Taxes

Income tax expense was $38.6 million in the second quarter of 2024, compared to $31.7 million in the first quarter of 2024 and $36.0 million in the second quarter of 2023. The Company's effective tax rate, including the effect of non-controlling interest, was 21.7% in the second quarter of 2024, compared to 21.9% in the first quarter of 2024 and 22.0% in the second quarter of 2023.

Financial Condition

Balance Sheet

Total assets of the Company were $30.6 billion at June 30, 2024 and $31.7 billion at December 31, 2023. Earning assets (excluding the allowance for credit losses on loans and fair value adjustments on debt securities) amounted to $29.8 billion at June 30, 2024 and $31.1 billion at December 31, 2023, and consisted of 58% in loans and 33% in investment securities at June 30, 2024.

At June 30, 2024, total loans decreased $42.4 million or .25%, compared to balances at December 31, 2023. The decrease was mainly due to declines in business real estate, construction and consumer credit card loans of $146.8 million, $50.2 million, and $23.0 million, respectively. These decreases were partly offset by an increase of $71.7 million in business loans, mainly due to growth in commercial and industrial lending and tax-free loan balances. In addition, personal real estate loans increased $29.1 million, while consumer loans, which includes automobile, marine and RV, fixed rate home equity and other consumer loans, increased $67.9 million, mainly due to growth in other consumer loans.

Total available for sale debt securities, excluding fair value adjustments, decreased $1.3 billion at June 30, 2024 compared to December 31, 2023. Purchases of available for sale debt securities during this period totaled $1.1 billion, offset by available for sale debt security sales, maturities and pay downs of $2.4 billion. The decline in available for sale debit securities was mainly the result of lower balances of mortgage-backed securities, asset-backed securities and state and municipal obligations, which decreased $812.5 million, $554.0 million, and $476.7 million, respectively, at June 30, 2024 compared to December 31, 2023. These decreases were partly offset by an increase of $820.0 million in balances of U.S. government and federal agency obligations. At June 30, 2024, the duration of the available for sale investment portfolio was 4.0 years, and maturities and pay downs of approximately $1.6 billion are expected to occur during the next 12 months. The Company does not have any investment securities classified as held-to-maturity.

Total deposits at June 30, 2024 amounted to $24.3 billion, a decrease of $1.1 billion compared to December 31, 2023. The decline in deposits largely resulted from a decrease in demand deposits, mainly in business demand deposits (decrease of $660.2 million). Additionally, certificate of deposit balances decreased $456.9 million and interest checking balances decreased $150.3 million from balances at December 31, 2023. The Company’s borrowings totaled $2.6 billion at June 30, 2024, a decrease of $354.8 million from balances at December 31, 2023, mainly due to a decline in FHLB advances, which were repaid in 2023.

Interest earning balances at the Federal Reserve Bank, which have overnight maturities and are used for general liquidity purposes, totaled $2.2 billion at June 30, 2024 and decreased $24.0 million from December 31, 2023 balances. At June 30, 2024, the Company did not have a balance of federal funds sold, which are funds lent to the Company's correspondent bank customers with overnight maturities. The fair value of the available for sale debt portfolio was $8.5 billion at June 30, 2024 and included an unrealized net loss of $1.1 billion. The total net unrealized loss included net losses of $926.9 million on mortgage-backed and asset-backed securities and $93.9 million on state and municipal obligations.

Resale agreements, maturing through 2029, totaled $475.0 million at June 30, 2024. Under these agreements, the Company lends funds to upstream financial institutions and holds marketable securities, safe-kept by a third-party custodian, as collateral. This collateral totaled $490.3 million in fair value at June 30, 2024. $125.0 million of the Company's resale agreements will mature in the next 12 months.

The Company's available for sale debt securities portfolio has a diverse mix of high quality and liquid investment securities with a duration of 4.0 years at June 30, 2024. Approximately $1.6 billion of the Company's available for sale debt portfolio is expected to mature or pay down during the next 12 months, and these funds offer substantial resources to meet either new loan demand or offset potential reductions in the Company's deposit funding base. The Company pledges portions of its investment securities portfolio to secure public fund deposits, securities sold under agreements to repurchase, trust funds, letters of credit issued by the FHLB, and borrowing capacity at the FHLB and the Federal Reserve Bank.

The average loans to deposits ratio is a measure of a bank's liquidity, and the Company’s average loans to deposits ratio was 70.3% for the six months ended June 30, 2024. Core customer deposits, defined as non-interest bearing, interest checking, savings, and money market deposit accounts totaled $21.9 billion and represented 90.0% of the Company's total deposits at June 30, 2024. These core deposits are normally less volatile, as they are often with customer relationships tied to other products offered by the Company, promoting long lasting relationships and stable funding sources. Core deposits decreased $627.7 million at June 30, 2024 compared to December 31, 2023, primarily due to decreases in commercial, wealth, and consumer segment deposits of $371.1 million, $225.5 million, and $70.9 million, respectively. While the Company considers core consumer and wealth management deposits less volatile, corporate deposits could decline if interest rates increase significantly, encouraging corporate customers to increase investing activities, or if the economy deteriorates and companies experience lower cash inflows, reducing deposit balances. If these corporate deposits decline, the Company's funding needs may be met by liquidity supplied by investment security maturities and pay downs expected to total $1.6 billion over the next year, as noted above. In addition, as shown in the table of collateral available for future advances below, the Company has borrowing capacity of $6.3 billion through advances from the FHLB and the Federal Reserve.

Certificates of deposit of $100,000 or greater totaled $1.4 billion at June 30, 2024. These deposits are normally considered more volatile and higher costing, and comprised 5.8% of total deposits at June 30, 2024.

Amid the banking sector's period of uncertainty during the second quarter of 2023, the Company issued several tranches of short-term brokered certificates of deposit totaling $1.2 billion, which all matured by December 31, 2023. While it is not clear how many brokered certificates of deposit the market would allow the Company to issue, the Company believes brokered certificates of deposits may be an additional, reliable source of liquidity during periods of stress in the banking industry.

Other important components of liquidity are the level of borrowings from third party sources and the availability of future credit. During 2024, the Company's outside borrowings have mainly been comprised of federal funds purchased and repurchase agreements, as follows:

(In thousands)	June 30, 2024		June 30, 2023		December 31, 2023
Borrowings:
Federal funds purchased	$	254,720	$	511,400	$	261,305

Other debt	3,984		5,613		1,404
Total	$	2,555,383	$	3,883,634	$	2,910,219

Federal funds purchased, which totaled $254.7 million at June 30, 2024, are unsecured overnight borrowings obtained mainly from upstream correspondent banks with which the Company maintains approved lines of credit. At June 30, 2024, the Company had approved lines of credit totaling $3.5 billion. Since these borrowings are unsecured and limited by market trading activity, their availability may be less certain than collateralized sources of borrowings. Retail repurchase agreements are offered to customers wishing to earn interest in highly liquid balances and are used by the Company as a funding source considered to be stable, but short-term in nature. Repurchase agreements are collateralized by securities in the Company's investment portfolio. Total repurchase agreements at June 30, 2024 were comprised of non-insured customer funds totaling $2.3 billion, and securities pledged as collateral for these retail agreements totaled $2.3 billion at June 30, 2024. The Company also borrows on a secured basis through advances from the FHLB. The advances are generally short-term, fixed interest rate borrowings. There were no advances outstanding from the FHLB at June 30, 2024.

The Company pledges certain assets, including loans and investment securities, to both the Federal Reserve Bank (FRB) and the FHLB as security to establish lines of credit and borrow from these entities. Based on the amount and type of collateral pledged, the FHLB establishes a collateral value from which the Company may draw advances against the collateral. Additionally, this collateral is used to enable the FHLB to issue letters of credit in favor of public fund depositors of the Company. The FRB also establishes a collateral value of assets pledged and permits borrowings from the discount window. The following table reflects the collateral value of assets pledged, borrowings, and letters of credit outstanding, in addition to the estimated future funding capacity available to the Company at June 30, 2024.

The Company receives outside ratings from both Standard & Poor’s and Moody’s on both the consolidated company and its subsidiary bank, Commerce Bank. These ratings are as follows:

	Standard & Poor’s	Moody’s
Commerce Bancshares, Inc.
Issuer rating	A-
Rating outlook	Stable
Commerce Bank
Issuer rating	A	A3
Baseline credit assessment		a2
Short-term rating	A-1	P-1
Rating outlook	Stable	Stable

The Company considers these ratings to be indications of a sound capital base and strong liquidity and believes that these ratings would help ensure the ready marketability of its commercial paper, should the need arise. No commercial paper has been outstanding during the past ten years. The Company has no subordinated or hybrid debt instruments which would affect future borrowing capacity. Because of its lack of significant long-term debt, the Company believes that through its Commercial Tradable Products division or in other public debt markets, it could generate additional liquidity from sources such as jumbo certificates of deposit, privately placed corporate notes or other forms of debt.

The cash flows from the operating, investing and financing activities of the Company resulted in a net decrease in cash, cash equivalents and restricted cash of $142.5 million during the first six months of 2024, as reported in the consolidated statements of cash flows in this report. Operating activities, consisting mainly of net income adjusted for certain non-cash items, provided cash flow of $282.8 million and have historically been a stable source of funds. Investing activities, which occur mainly in the loan and investment securities portfolios, provided cash of $1.2 billion. Activity in the investment securities portfolio provided cash of $1.2 billion from sales, maturities, and pay downs (net of purchases). This increase in investing cash flows was further supported by shrinking in the loan portfolio, which provided cash of $23.7 million. These increases were partly offset by purchases of securities under agreements to resell (net of repayments), which used cash of $25.0 million. Investing activities are somewhat unique to financial institutions in that, while large sums of cash flow are normally used to fund growth in investment securities, loans, or other bank assets, they are normally dependent on the financing activities described below. Financing activities used cash of $1.6 billion, largely resulting from net decreases in deposits of $1.1 billion and a net decrease of $357.4 million in federal funds purchased and securities sold under agreements to repurchase during the first six months of 2024. Additionally, purchases of treasury stock and cash dividends used cash of $79.9 million and $70.1 million, respectively.

Capital Management

The Company met all capital adequacy requirements and had regulatory capital ratios in excess of the levels established for well-capitalized institutions at June 30, 2024 and December 31, 2023, as shown in the following table.

(Dollars in thousands)	June 30, 2024			December 31, 2023			Minimum Capital Requirement		Capital Conservation Buffer		Minimum Ratios Requirement including Capital Conservation Buffer		Minimum Ratios for Well-Capitalized Banks *

The Company is subject to a 2.5% capital conservation buffer, which is an amount above the minimum ratios under capital adequacy guidelines, and is intended to absorb losses during periods of economic stress. Failure to maintain the buffer will result in constraints on dividends, share repurchases, and executive compensation.

In the first quarter of 2020, the interim final rule of the Federal Reserve Bank and other U.S. banking agencies became effective, providing banks that adopted CECL (ASU 2016-13) during the 2020 calendar year the option to delay recognizing the estimated impact on regulatory capital until after a two year deferral period, followed by a three year transition period. In connection with the adoption of CECL on January 1, 2020, the Company elected to utilize this option. As a result, the two year deferral period for the Company extended through December 31, 2021. Beginning on January 1, 2022, the Company was required to phase in 25% of the previously deferred estimated capital impact of CECL, with an additional 25% to be phased in at the beginning of each subsequent year until fully phased in by the first quarter of 2025.

The Company maintains a treasury stock buyback program under authorizations by its Board of Directors (the Board) and periodically purchases stock in the open market. In April 2024, the Board approved the purchase of additional shares, bringing the total shares authorized for purchase to 5,000,000 at April 17, 2024. During the six months ended June 30, 2024, the Company purchased 1,491,902 shares at an average price of $53.55 in open market purchases and through stock-based compensation transactions. At June 30, 2024, 4,315,095 shares remained available for purchase under the current Board authorization.

The Company's common stock dividend policy reflects its earnings outlook, desired payout ratios, the need to maintain adequate capital levels and alternative investment options. The Company paid a $.270 per share cash dividend on its common stock in the second quarter of 2024, which was a 5.1% increase compared to its 2023 quarterly dividend.

Material Cash Requirements, Commitments, Off-Balance Sheet Arrangements and Contingencies

The Company's material cash requirements include commitments for contractual obligations (both short-term and long-term), commitments to extend credit, and off-balance sheet arrangements. The Company's material cash requirements for the next 12 months are primarily to fund loan growth. Additionally, the Company will utilize cash to fund deposit maturities and withdrawals that may occur in the next 12 months. Other contractual obligations, purchase commitments, lease obligations, and unfunded commitments may require cash payments by the Company within the next 12 months, and these are further discussed in the Company's 2023 Annual Report on Form 10-K. Further discussion of the Company's longer-term material cash obligations and sources for fulfilling those obligations is below.

In the normal course of business, various commitments and contingent liabilities arise that are not required to be recorded on the balance sheet. The most significant of these are loan commitments, which at June 30, 2024 totaled $14.9 billion (including $5.7 billion in unused, approved credit card lines). In addition, the Company enters into standby and commercial letters of credit. The contractual amount of standby and commercial letters of credit totaled $619.0 million and $4.9 million, respectively, at June 30, 2024. As many commitments expire unused or only partially used, these totals do not necessarily reflect future cash requirements. The allowance for these commitments is recorded in the Company’s liability for unfunded lending commitments within other liabilities on its consolidated balance sheets. At June 30, 2024, the liability for unfunded lending commitments totaled $20.7 million. See further discussion of the liability for unfunded lending commitments in Note 2 to the consolidated financial statements.

The Company regularly purchases various state tax credits arising from third party property redevelopment. These credits are either resold to third parties at a profit or retained for use by the Company. During the first six months of 2024, purchases and sales of tax credits amounted to $53.7 million and $68.0 million, respectively. Fees from sales of tax credits were $2.9 million for the six months ended June 30, 2024, compared to $1.0 million in the same period last year. At June 30, 2024, the Company expected to fund outstanding purchase commitments of $111.0 million during the remainder of 2024 and had purchase commitments of $484.5 million that it expects to fund from 2025 through 2030.

The Company continued to maintain a strong liquidity position throughout the first six months of 2024. Through the various sources of liquidity described above, the Company maintains a liquidity position that it believes will adequately satisfy its financial obligations.

Consumer

For the six months ended June 30, 2024, income before income taxes for the Consumer segment decreased $37.8 million, or 23.3%, compared to the first six months of 2023. The decrease in income before income taxes was mainly due to a decline in net interest income of $31.3 million, or 11.0%, and increases in non-interest expense of $1.8 million, or 1.1%, and the provision for credit losses of $5.2 million. Net interest income declined mainly due to a $48.1 million increase in deposit interest expense. This decrease was partly offset by higher loan interest income of $13.6 million and a $4.0 million increase in net allocated funding credits assigned to the Consumer segment's loan and deposit portfolios. Non-interest income increased $501 thousand, or 1.0%, mainly due to higher net bank card fees (mainly credit and debit card fees) and deposit account fees. Non-interest expense increased over the same period in the previous year mainly due to higher allocated costs for information technology and retail support, partly offset by lower marketing expense. The increase in the provision for credit losses over the first six months of 2023 was mainly due to higher consumer credit card loan net charge-offs.

Commercial

For the six months ended June 30, 2024, income before income taxes for the Commercial segment decreased $15.2 million, or 7.8%, compared to the same period in the previous year. This decrease was mainly due to lower net interest income and non-interest expense, partly offset by higher non-interest income. Net interest income decreased $13.3 million, or 5.0%, mainly due to lower net allocated funding credits of $28.2 million, coupled with higher interest expense on deposits and customer repurchase agreements of $28.6 million and $6.4 million, respectively, partly offset by higher loan interest income of $50.8 million. Non-interest income increased $5.9 million, or 4.8%, over the previous year mainly due to growth in deposit account fees (mainly corporate cash management fees), tax credit sales fees, capital market fees and loan commitment fees. These increases were partly offset by decreases in net bank card fees (mainly corporate card fees), letter of credit fees and swap fees. Non-interest expense increased $7.5 million, or 3.9%, mainly due to higher salaries and benefits expense and allocated service and support costs for software, electronic banking and management expense. These increases were partly offset by lower allocated commercial sales and payment support costs. The provision for credit losses increased $283 thousand over the same period last year, mainly due to higher commercial credit card and commercial loan net charge-offs.

70

Wealth

Wealth segment pre-tax profitability for the six months ended June 30, 2024 increased $4.2 million, or 5.2%, over the same period in the previous year. Net interest income decreased $8.0 million, or 15.0%, mainly due to a $15.3 million increase in deposit interest expense. This decrease was partly offset by a $1.6 million increase in net allocated funding credits and a $5.7 million increase in loan interest income. Non-interest income increased $10.5 million, or 9.8%, over the prior year largely due to higher private client and institutional trust fees and cash sweep commissions, partly offset by lower brokerage fees. Non-interest expense decreased $1.7 million, or 2.1%, mainly due to deconversion expense recorded in the prior year and lower professional fees, partly offset by higher salaries and benefits expense. The provision for credit losses decreased $17 thousand from the same period last year due to lower overdraft loan net charge-offs.

The Other/Elimination category in the preceding table includes the activity of various support and overhead operating units of the Company, in addition to the investment securities portfolio and other items not allocated to the segments. In accordance with the Company’s transfer pricing procedures, the difference between the total provision for credit losses and total net charge-offs/recoveries is not allocated to a business segment and is included in this category. The pre-tax profitability in this category was $56.1 million higher than in the same period last year. Unallocated securities gains were $3.0 million in the first six months of 2024 compared to gains of $3.1 million in 2023. Also, the unallocated provision for credit losses decreased $13.1 million, primarily driven by decreases in the provision for credit losses on loans and the liability for unfunded lending commitments, which are both not allocated to the segments for management reporting purposes. Net charge-offs are allocated to the segments when incurred for management reporting purposes. The provision for credit losses on loans in the first six months of 2024 was $14.8 million, or $3.8 million lower than net charge-offs, due to a decrease in the allowance for credit losses on loans. In the comparable period last year, the provision for credit losses on loans was $21.8 million, or $8.5 million higher than net charge-offs, due to an increase in the allowance for credit losses on loans. For the six months ended June 30, 2024, the Company's provision on unfunded lending commitments was a benefit of $4.5 million. Additionally, net interest income increased $62.7 million. This increase to pre-tax profitability was partly offset by lower non-interest income of $1.0 million and higher non-interest expense of $18.5 million.

71

Regulatory Changes

Deposit Insurance

On November 16, 2023, Federal Deposit Insurance Corporation (“FDIC”) issued a final rule to impose a special assessment to recover losses to the FDIC’s Deposit Insurance Fund following the failure of two financial institutions. The rule applies to all insured depository institutions and stated that the special assessment would be collected at an annual rate of approximately 13.4 basis points for an anticipated total of eight quarterly assessment periods. Because the estimated loss pursuant to the systemic risk determination will be periodically adjusted, the FDIC could:

•Cease collection early, if it has collected enough to recover actual or estimated losses;

•Extend the special assessment collection period one or more quarters beyond the initial eight-quarter collection period, if actual or estimated losses exceed the amounts collected; and

•Impose a final shortfall special assessment on a one-time basis after the receiverships for certain failed banks terminate, if actual losses exceed the amounts collected.

During the first quarter of 2024, the FDIC increased its estimate of losses to the Deposit Insurance Fund and in turn increased its estimated special assessment, announcing that the special assessment would come in the form of a June 2024 invoice based on its March 31, 2024 estimate loss in the Deposit Insurance Fund. The Company paid $2.0 million towards the special assessment in June 2024 and has an accrual of $16.8 million at June 30, 2024 for FDIC special assessment liabilities.

SEC Climate Disclosure Rule

On March 6, 2024, the Securities and Exchange Commission adopted rules to enhance and standardize climate-related disclosures by public companies and in public offerings. This climate-related disclosure rule will have significant disclosure impact to the public companies affected, including the Company. Among many other items, this rule requires companies to disclose:

•Climate-related risks that have had or are reasonably likely to have a material impact on the registrant’s business strategy, results of operations, or financial condition;

•The actual and potential material impacts of any identified climate-related risks on the registrant’s strategy, business model, and outlook;

•If, as part of its strategy, a registrant has undertaken activities to mitigate or adapt to a material climate-related risk, a quantitative and qualitative description of material expenditures incurred and material impacts on financial estimates and assumptions that directly result from such mitigation or adaptation activities;

•Specified disclosures regarding a registrant’s activities, if any, to mitigate or adapt to a material climate-related risk including the use, if any, of transition plans, scenario analysis, or internal carbon prices;

•Scope 1 and Scope 2 greenhouse gas (GHG) emissions, when material; and

•Capitalized costs, expenditures, charges, and losses incurred as a result of severe weather events or other natural conditions.

However, in April 2024, the SEC issued an order to stay the rules pending judicial review, due to legal challenges to this mandate. The SEC has not issued an update since April 2024.

Impact of Recently Issued Accounting Standards

Disclosure Improvements The FASB issued ASU 2023-06, "Disclosure Improvements: Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative," in October 2023. The amendments in this Update modify the disclosure or presentation requirements of a variety of topics in the Codification. Certain of the amendments represent clarifications to or technical corrections of the current requirements. The effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The adoption is not expected to have a significant effect on the Company's consolidated financial statements.

Segment Reporting The FASB issued ASU 2023-07, "Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures", in November 2023. The amendments require disclosure of significant segment expenses and other segment items on an annual and interim basis. Public entities are required to disclose significant expense categories and amounts for each reportable segment, as well as the amount and a description of the composition of other segment items. Significant expense categories are derived from expenses that are regularly provided to an entity’s chief operating decision-maker (“CODM”), and included in a segment’s reported measures of profit or loss. Public entities are also required to disclose the title and position of the CODM and explain how the CODM uses the reported measures of profit or loss in assessing segment performance and deciding how to allocate resources. This Update requires interim disclosures of certain segment-related disclosures that previously were only required annually. This Update requires annual disclosures for fiscal years beginning January 1, 2024 and interim disclosures for fiscal years beginning January 1, 2025. Early adoption is permitted. The Company is required to apply the amendments in this Update retrospectively to all prior periods presented in the financial statements. Other than the inclusion of additional disclosures, the adoption of this ASU is not expected to have a significant effect on the Company's consolidated financial statements.

Income Taxes The FASB issued ASU 2023-09, "Income Taxes (Topic 740) - Improvements to Income Tax Disclosures", in December 2023. The amendments in this Update require additional disclosures regarding the rate reconciliation and income taxes paid. This Update also removed certain existing disclosure requirements. This Update is effective for annual periods beginning January 1, 2025. Early adoption is permitted. The amendments in this Update should be applied on a prospective basis, though retrospective application is permitted. Other than the inclusion of additional disclosures, the adoption is not expected to have a significant effect on the Company's consolidated financial statements.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest rate risk management focuses on maintaining consistent growth in net interest income within Board-approved policy limits. The Company primarily uses earnings simulation models to analyze net interest income sensitivity to movement in interest rates. The Company performs monthly simulations that model interest rate movements and risk in accordance with changes to its balance sheet composition. For further discussion of the Company’s market risk, see the Interest Rate Sensitivity section of Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the Company’s 2023 Annual Report on Form 10-K.

The table below shows the effects of gradual shifts in interest rates over a twelve month period on the Company’s net interest income versus the Company's net interest income in a flat rate scenario.  The simulation presents three rising rate scenarios and three falling rate scenarios, and in these scenarios, rates are assumed to change evenly over 12 months, while the balance sheet remains flat.

The Company utilizes this simulation both for monitoring interest rate risk and for liquidity planning purposes.  While the future effects of rising and falling rates on deposit balances cannot be known, the Company maintains a practice of running multiple rate scenarios, when relevant, to better understand interest rate risk and its effect on the Company’s performance. 

	June 30, 2024				March 31, 2024
(Dollars in millions)	$ Change in Net Interest Income		% Change in Net Interest Income		$ Change in Net Interest Income		% Change in Net Interest Income
300 basis points rising	$	(7.2)	(.67)	%	$	(13.9)	(1.37)	%
200 basis points rising	(9.0)		(.84)		(13.6)		(1.35)
100 basis points rising	(5.1)		(.47)		(7.4)		(.73)
100 basis points falling	$	(9.3)	(.86)	%	$	(5.8)	(.57)	%
200 basis points falling	(26.1)		(2.44)		(20.3)		(2.01)
300 basis points falling	(44.6)		(4.16)		(37.9)		(3.73)

Under the simulation, in the three rising rate scenarios, interest rate risk is improved compared to the scenarios in the previous quarter and in the three falling rate scenarios, interest rate risk is more negative when compared to the scenarios in the previous quarter. This change was primarily due to higher interest earning cash balances at the Federal Reserve coupled with the completion of the planned repositioning of a portion of the investment securities portfolio.

The comparison above provides insight into potential effects of changes in rates on net interest income.  The Company believes that its approach to interest rate risk has appropriately considered its susceptibility to both rising and falling rates and has adopted strategies which minimize the impact of interest rate risk.

Item 4. CONTROLS AND PROCEDURES

An evaluation was performed under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) as of June 30, 2024. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective. There were no changes in the Company's internal control over financial reporting that occurred during the last fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

Principles Of Consolidation And Presentation

Principles of Consolidation and Presentation

The accompanying consolidated financial statements include the accounts of Commerce Bancshares, Inc. and all majority-owned subsidiaries (the Company). Most of the Company's operations are conducted by its subsidiary bank, Commerce Bank (the Bank). The consolidated financial statements in this report have not been audited by an independent registered public accounting firm, but in the opinion of management, all adjustments necessary to present fairly the financial position and the results of operations for the interim periods have been made. All such adjustments are of a normal recurring nature. All significant intercompany accounts and transactions have been eliminated. Certain reclassifications were made to 2023 data to conform to current year presentation. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheets and revenues and expenses for the periods. Actual results could differ significantly from those estimates. Management has evaluated subsequent events for potential recognition or disclosure. The results of operations for the six month period ended June 30, 2024 are not necessarily indicative of results to be attained for the full year or any other interim period.

The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and with the instructions to Form 10-Q adopted by the Securities and Exchange Commission. Accordingly, the financial statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the Company's most recent Annual Report on Form 10-K, containing the latest audited consolidated financial statements and notes thereto.

Accrued interest receivable totaled $71.9 million at both June 30, 2024 and December 31, 2023, and was included within other assets on the consolidated balance sheets. For the three months ended June 30, 2024, the Company wrote-off accrued interest by reversing interest income of $341 thousand and $1.6 million in the Commercial and Personal Banking portfolios, respectively. Similarly, for the six months ended June 30, 2024, the Company wrote off accrued interest of $435 thousand and $3.1 million in the Commercial and Personal Banking portfolios, respectively. For the three months ended June 30, 2023, the Company reversed interest income of $43 thousand and $1.1 million in the Commercial and Personal Banking portfolios, respectively, and in the six months ended June 30, 2023, reversed $77 thousand and $2.2 million in the Commercial and Personal Banking portfolios, respectively.

At June 30, 2024, loans of $3.6 billion were pledged at the Federal Home Loan Bank as collateral for borrowings and letters of credit obtained to secure public deposits. Additional loans of $2.9 billion were pledged at the Federal Reserve Bank as collateral for discount window borrowings.

Allowance for credit losses

The allowance for credit losses is measured using an average historical loss model which incorporates relevant information about past events (including historical credit loss experience on loans with similar risk characteristics), current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the loans. The allowance for credit losses is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics including borrower type, collateral type and expected credit loss patterns. Loans that do not share similar risk characteristics, primarily large loans on non-accrual status, are evaluated on an individual basis.

For loans evaluated for credit losses on a collective basis, average historical loss rates are calculated for each pool using the Company’s historical net charge-offs (combined charge-offs and recoveries by observable historical reporting period) and outstanding loan balances during a lookback period. Lookback periods can be different based on the individual pool and represent management’s credit expectations for the pool of loans over the remaining contractual life. In certain loan pools, if the Company’s own historical loss rate is not reflective of the loss expectations, the historical loss rate is augmented by industry and peer data. The calculated average net charge-off rate is then adjusted for current conditions and reasonable and supportable forecasts. These adjustments increase or decrease the average historical loss rate to reflect expectations of future losses given a single path economic forecast of key macroeconomic variables including GDP, disposable income, various interest rates, unemployment rate, consumer price index (CPI) inflation rate, housing price index (HPI), commercial real estate price index (CREPI) and market volatility. The adjustments are based on results from various regression models projecting the impact of the macroeconomic variables to loss rates. The forecast is used for a reasonable and supportable period before reverting back to historical averages using a straight-line method. The forecast-adjusted loss rate is applied to the amortized cost of loans over the remaining contractual lives, adjusted for expected prepayments. The contractual term excludes expected extensions (except for contractual extensions at the option of the customer), renewals and modifications. Credit cards and certain similar consumer lines of credit do not have stated maturities and therefore, for these loan classes, remaining contractual lives are determined by estimating future cash flows expected to be received from customers until payments have been fully allocated to outstanding balances. Additionally, the allowance for credit losses considers other qualitative factors not included in historical loss rates or macroeconomic forecast such as changes in portfolio composition, underwriting practices, or significant unique events or conditions.

Key assumptions in the Company’s allowance for credit loss model include the economic forecast, the reasonable and supportable period, forecasted macro-economic variables, prepayment assumptions and qualitative factors applied for portfolio composition changes, underwriting practices, or significant unique events or conditions. The assumptions utilized in estimating the Company’s allowance for credit losses at June 30, 2024 and March 31, 2024 are discussed below.

The liability for unfunded lending commitments utilizes the same model as the allowance for credit losses on loans, however, the liability for unfunded lending commitments incorporates an assumption for the portion of unfunded commitments that are expected to be funded.

Sensitivity in the Allowance for Credit Loss model

The allowance for credit losses is an estimate that requires significant judgment including projections of the macro-economic environment. The forecasted macro-economic environment continuously changes which can cause fluctuations in the estimate of expected credit losses.

The current forecast projects continued low unemployment. It is expected that the Federal Reserve will start cutting rates in September of 2024 and fiscal policy will be maintained.

Updated information on inflation and labor market trends could impact the Federal Reserve's decision on the timing and degree of rate reductions. The market's response to these events along with other economic, political, and social developments regionally, nationally, and even globally could significantly modify economic projections used in the estimation of the allowance for credit losses. The upcoming presidential election could result in policy changes that might also impact the estimation of the allowance for credit losses.

Potential changes in any one economic variable may or may not affect the overall allowance because a variety of economic variables and inputs are considered in estimating the allowance, and changes in those variables and inputs may not occur at the same rate, may not be consistent across product types, and may have offsetting impacts to other changing variables and inputs.

A summary of the activity in the allowance for credit losses on loans and the liability for unfunded lending commitments for the three and six months ended June 30, 2024 and 2023, respectively, follows:

Credit quality indicators

The following table provides information about the credit quality of the Commercial loan portfolio. The Company utilizes an internal risk rating system comprised of a series of grades to categorize loans according to perceived risk associated with the expectation of debt repayment based on borrower specific information including, but not limited to, current financial information, historical payment experience, industry information, collateral levels and collateral types. The “pass” category consists of a range of loan grades that reflect increasing, though still acceptable, risk. A loan is assigned the risk rating at origination and then monitored throughout the contractual term for possible risk rating changes. Movement of risk through the various grade levels in the “pass” category is monitored for early identification of credit deterioration. The “special mention” rating is applied to loans where the borrower exhibits negative financial trends due to borrower specific or systemic conditions that, if left uncorrected, threaten its capacity to meet its debt obligations. The borrower is believed to have sufficient financial flexibility to react to and resolve its negative financial situation. It is a transitional grade that is closely monitored for improvement or deterioration. The “substandard” rating is applied to loans where the borrower exhibits well-defined weaknesses that jeopardize its continued performance and are of a severity that the distinct possibility of default exists. Loans are placed on “non-accrual” when management does not expect to collect payments consistent with acceptable and agreed upon terms of repayment.

All loans are analyzed for risk rating updates annually. For larger loans, rating assessments may be more frequent if relevant information is obtained earlier through debt covenant monitoring or overall relationship management. Smaller loans are monitored as identified by the loan officer based on the risk profile of the individual borrower or if the loan becomes past

due related to credit issues. Loans rated Special Mention, Substandard or Non-accrual are subject to quarterly review and monitoring processes. In addition to the regular monitoring performed by the lending personnel and credit committees, loans are subject to review by a credit review department which verifies the appropriateness of the risk ratings for the loans chosen as part of its risk-based review plan.

The risk category of loans in the Commercial portfolio as of June 30, 2024 and December 31, 2023 are as follows:

Collateral-dependent loans

The Company's collateral-dependent loans are comprised of large loans on non-accrual status. The Company requires that collateral-dependent loans are either over-collateralized or carry collateral equal to the amortized cost of the loan. The following table presents the amortized cost basis of collateral-dependent loans as of June 30, 2024 and December 31, 2023.

Other Personal Banking loan information

As noted above, the credit quality of Personal Banking loans is monitored primarily on the basis of aging/delinquency, and this information is provided in the table in the above section on "Credit quality indicators." In addition, FICO scores are obtained and updated on a quarterly basis for most of the loans in the Personal Banking portfolio. This is a published credit score designed to measure the risk of default by taking into account various factors from a borrower's financial history and is considered supplementary information utilized by the Company, as management does not consider this information in evaluating the allowance for credit losses on loans. The Bank normally obtains a FICO score at the loan's origination and renewal dates, and updates are obtained on a quarterly basis. Excluded from the table below are certain personal real estate loans for which FICO scores are not obtained because the loans generally pertain to commercial customer activities and are often underwritten with other collateral considerations. These loans totaled $170.1 million at June 30, 2024 and $168.9 million at December 31, 2023. The table also excludes consumer loans related to the Company's patient healthcare loan program, which totaled $220.5 million at June 30, 2024 and $211.3 million at December 31, 2023. As the healthcare loans are guaranteed by the hospital, customer FICO scores are not obtained for these loans. The personal real estate loans and consumer loans excluded below totaled less than 7% of the Personal Banking portfolio. For the remainder of loans in the Personal Banking portfolio, the table below shows the percentage of balances outstanding at June 30, 2024 and December 31, 2023 by FICO score.

Modifications for borrowers experiencing financial difficulty

When borrowers are experiencing financial difficulty, the Company may agree to modify the contractual terms of a loan to a borrower in order to assist the borrower in repaying principal and interest owed to the Company.

The Company's modifications of loans to borrowers experiencing financial difficulty are generally in the form of term extensions, repayment plans, payment deferrals, forbearance agreements, interest rate reductions, forgiveness of interest and/or fees, or any combination thereof. Commercial loans modified to borrowers experiencing financial difficulty are primarily loans that are substandard or non-accrual, where the maturity date was extended. Modifications on personal real estate loans are primarily those placed on forbearance plans, repayment plans, or deferral plans where monthly payments are suspended for a period of time or past due amounts are paid off over a certain period of time in the future or set up as a balloon payment at maturity. Modifications to certain credit card and other small consumer loans are often modified under debt counseling programs that can reduce the contractual rate or, in certain instances, forgive certain fees and interest charges. Other consumer loans modified to borrowers experiencing financial difficulty consist of various other workout arrangements with consumer customers.

The following tables present the amortized cost at June 30, 2024 of loans that were modified during the three and six months ended June 30, 2024 and the amortized cost of at June 30, 2023 of loans that were modified during the three and six months ended June 30, 2023.

The estimate of lifetime expected losses utilized in the allowance for credit losses model is developed using average historical experience on loans with similar risk characteristics, which includes losses from modifications of loans to borrowers experiencing financial difficulty. As a result, a change to the allowance for credit losses is generally not recorded upon

modification. For modifications to loans made to borrowers experiencing financial difficulty that are placed on non-accrual status, the Company determines the allowance for credit losses on an individual evaluation, using the same process that it utilizes for other loans on non-accrual status. Modifications made to commercial loans which are not on non-accrual status for borrowers experiencing financial difficulty are collectively evaluated based on internal risk rating, loan type, delinquency, historical experience, and current economic factors. Modifications made to borrowers experiencing financial difficulty for personal banking loans which are not on non-accrual status are collectively evaluated based on loan type, delinquency, historical experience, and current economic factors.

If a loan to a borrower experiencing financial difficulty is modified and subsequently deemed uncollectible, the allowance for credit losses continues to be based on individual evaluation, if that loan is already on non-accrual status. For those loans, the allowance for credit losses is estimated using discounted expected cash flows or the fair value of collateral. If an accruing loan made to a borrower experiencing financial difficulty is modified and subsequently deemed uncollectible, the loan's risk rating is downgraded to non-accrual status and the loan's related allowance for credit losses is determined based on individual evaluation, or if necessary, the loan is charged off and collection efforts begin.

The following tables summarize the financial impact of loan modifications and payment deferrals during the three and six months ended June 30, 2024 and June 30, 2023.

The Company had commitments of $7.0 million and $28.4 million at June 30, 2024 and December 31, 2023, respectively, to lend additional funds to borrowers experiencing financial difficulty and for whom the Company has modified the terms of loans in the form of an interest rate reduction; an other-than-insignificant payment delay; forgiveness of principal, interest, or fees; or a term extension during the current reporting period.

The following tables provide the amortized cost basis at June 30, 2024 of loans to borrowers experiencing financial difficulty that had a payment default during the three and six months ended June 30, 2024 and were modified within the 12 months preceding the payment default, as well as the amortized cost basis at June 30, 2023 of loans to borrowers experiencing financial difficulty that had a payment default during the three and six months ended June 30, 2023 and had been modified on or after January 1, 2023 (the date we adopted ASU 2022-02). For purposes of this disclosure, the Company considers "default" to mean 90 days or more past due as to interest or principal.

Loans held for sale

The Company designates certain long-term fixed rate personal real estate loans as held for sale, and the Company has elected the fair value option for these loans. The election of the fair value option aligns the accounting for these loans with the related economic hedges discussed in Note 11. The loans are primarily sold to Federal Home Loan Mortgage Corporation (FHLMC) and Federal National Mortgage Association (FNMA). At June 30, 2024, the fair value of these loans was $2.2 million, and the unpaid principal balance was $2.2 million.

The Company also designates certain student loan originations as held for sale. The borrowers are credit-worthy students who are attending colleges and universities. The loans are intended to be sold in the secondary market, and the Company maintains contracts with Sallie Mae to sell the loans within 210 days after the last disbursement to the student. These loans are carried at lower of cost or fair value, which at June 30, 2024 totaled $448 thousand.

At June 30, 2024, none of the loans held for sale were on non-accrual status or 90 days past due and still accruing interest.

Foreclosed real estate/repossessed assets

The Company’s holdings of foreclosed real estate totaled $143 thousand and $270 thousand at June 30, 2024 and December 31, 2023, respectively, and included in those amounts were $143 thousand and $270 thousand at June 30, 2024 and December 31, 2023, respectively, of foreclosed residential real estate properties held as a result of obtaining physical possession. Personal property acquired in repossession, generally autos, totaled $2.2 million and $1.8 million at June 30, 2024 and December 31, 2023. Upon acquisition, these assets are recorded at fair value less estimated selling costs at the date of foreclosure, establishing a new cost basis. They are subsequently carried at the lower of this cost basis or fair value less estimated selling costs.

The Company’s equity securities are also discussed below. Other investment securities include Federal Reserve Bank (FRB) stock, Federal Home Loan Bank (FHLB) stock, and investments in portfolio concerns held by the Company’s private equity subsidiary. FRB stock and FHLB stock are held for debt and regulatory purposes. Investment in FRB stock is based on the capital structure of the investing bank, and investment in FHLB stock is tied to the asset size of the borrowing bank and the level of borrowings from the FHLB. These holdings are carried at cost. The Company’s private equity investments are carried at estimated fair value.

Equity Securities

The Company’s equity securities portfolio includes common and preferred stock with readily determinable fair values as well as equity securities with no readily determinable fair value. The Company has elected to measure equity securities with no readily determinable fair value at cost minus impairment, if any, plus or minus changes resulting from observable price changes for the identical or similar investment of the same issuer. At March 31, 2024, this portfolio included the Company’s 823,447 shares of Visa Inc. (“Visa”) Class B-1 common stock (formerly Class B common stock), which were held by Commerce Bancshares, Inc. The Company’s Visa Class B-1 shares had a carrying value of zero at March 31, 2024, as there had not been observable price changes in orderly transactions for identical or similar investments of the same issuer.

On April 8, 2024, Visa announced the commencement of a public offering to permit the exchange of its Class B-1 common stock for a combination of shares of its Class B-2 common stock and its Class C common stock (“Exchange Offer”). The Company tendered all of its Visa Class B-1 shares pursuant to the Exchange Offer. On May 3, 2024, the Exchange Offer closed, and in exchange for its 823,447 shares of Visa Class B-1 common stock, the Company received 411,723 shares of Visa Class B-2 common stock (which will be convertible under certain circumstances, as further described below, into Visa’s publicly traded Class A common stock at an initial rate of 1.5875 shares of Class A common for each share of Class B-2 common stock, subject to adjustment) and 163,404 shares of Visa Class C common stock which will automatically convert into four shares of Visa's Class A common stock (subject to future adjustments for any stock splits, recapitalizations or similar transactions) upon any transfer to a person other than a Visa member or an affiliate of a Visa member.

As a condition of participating in the exchange, the Company entered into a Makewhole Agreement with Visa that provides for cash payments to Visa to the extent (if any) that future adjustments to the conversion ratio for the Visa Class B-2 common stock to Class A common stock cause such ratio to fall below zero. Changes to the conversion ratio occur when Visa deposits funds to a litigation escrow established by Visa to pay settlements for certain covered litigation that pre-dated Visa’s initial public offering, for which Visa has been effectively indemnified by Visa USA members through reductions to the conversion ratio for its Class B-1 common stock. The purpose of the Makewhole Agreement is to preserve the economic benefit of these adjustments to the Class B-1 conversion ratio for the benefit of Visa’s Class A and Class C common stockholders following the exchange. As further described in Visa’s related Issuer Tender Offer Statement on Schedule TO and Prospectus, each dated April 8, 2024, publicly filed with the U. S. Securities and Exchange Commission, both the Makewhole Agreement and the related escrow fund and transfer restrictions on Visa’s Class B-1 common stock and the new Class B-2 common stock will terminate whenever the covered litigation is ultimately resolved, at which future date outstanding shares of Visa Class B-2 common stock will be convertible into shares of its Class A common stock at the then-applicable conversion ratio.

As a result of the exchange, the Company elected the measurement alternative approach for its Visa Class C common stock and marked the stock to fair value, recording a gain based on the conversion privilege of the Visa Class C common stock and the closing price of Visa Class A common stock. During the second quarter of 2024, the Company sold 436 thousand shares of Visa Class A common stock at an average price of $274.91, resulting in proceeds of $119.8 million. The Company’s remaining 54 thousand Visa Class C shares had a fair value of $57.2 million at June 30, 2024, and are subject to limited transfer restrictions that end on August 1, 2024. These shares are expected to continue to be marked to fair value on a recurring basis using the Visa Class A shares as evidence of orderly transactions between market participants for similar securities issued by Visa. The Company’s Visa Class B-2 common stock will continue to be carried at cost of $0 as the Company elected the measurement alternative approach for these shares as well, and there are not observable price changes in orderly transactions for identical or similar investments of the same issuer for the Visa Class B-2 shares held by the Company.

Available for sale debt securities portfolio

The majority of the Company’s investment portfolio is comprised of available for sale debt securities, which are carried at fair value with changes in fair value reported in accumulated other comprehensive income (AOCI). A summary of the available for sale debt securities by maturity groupings as of June 30, 2024 is shown below. The investment portfolio includes agency mortgage-backed securities, which are guaranteed by agencies such as FHLMC, FNMA, and Government National Mortgage Association (GNMA), in addition to non-agency mortgage-backed securities, which have no guarantee but are collateralized by commercial and residential mortgages. Also included are certain other asset-backed securities, which are primarily collateralized by credit cards, automobiles, student loans, and commercial loans. These securities differ from traditional debt securities primarily in that they may have uncertain maturity dates and are priced based on estimated prepayment rates on the underlying collateral.

Total available for sale debt securities	$	9,608,044	$	8,534,271

Investments in U.S. government and federal agency obligations include U.S. Treasury inflation-protected securities, which totaled $399.7 million, at fair value, at June 30, 2024. Interest earned on these securities increases with inflation and decreases with deflation, as measured by the non-seasonally adjusted Consumer Price Index (CPI-U). At maturity, the principal paid is the greater of an inflation-adjusted principal or the original principal.

Allowance for credit losses on available for sale debt securities

Securities for which fair value is less than amortized cost are reviewed for impairment. Special emphasis is placed on securities whose credit rating has fallen below Baa3 (Moody's) or BBB- (Standard & Poor's), whose fair values have fallen more than 20% below purchase price, or those which have been identified based on management’s judgment. These securities are placed on a watch list and cash flow analyses are prepared on an individual security basis. Certain securities are analyzed using a projected cash flow model, discounted to present value, and compared to the current amortized cost bases of the securities. The model uses input factors such as cash flow projections, contractual payments required, expected delinquency rates, credit support from other tranches, prepayment speeds, collateral loss severity rates (including loan to values), and various other information related to the underlying collateral. Securities not analyzed using the cash flow model are analyzed by reviewing credit ratings, credit support agreements, and industry knowledge to project future cash flows and any possible credit impairment.

At June 30, 2024, the fair value of securities on this watch list was $1.8 billion compared to $1.2 billion at December 31, 2023. Almost all of the securities included on the Company's watch list in the current quarter were experiencing unrealized loss positions due to the significant increase in interest rates and were analyzed outside of the cash flow model. At June 30, 2024, the securities on the Company's watch list that were not deemed to be solely related to increasing interest rates were securities backed by government-guaranteed student loans and are expected to perform as contractually required. As of June 30, 2024, the Company did not identify any securities for which a credit loss exists, and for the six months ended June 30, 2024 and 2023, the Company did not recognize a credit loss expense on any available for sale debt securities.

The table below summarizes debt securities available for sale in an unrealized loss position, aggregated by length of loss period, for which an allowance for credit losses has not been recorded at June 30, 2024 and December 31, 2023. Unrealized losses on these available for sale securities have not been recognized into income because after review, the securities were deemed not to be impaired. The unrealized losses on these securities are primarily attributable to changes in interest rates and current market conditions. At June 30, 2024, the Company does not intend to sell the securities, nor is it anticipated that it would be required to sell any of these securities at a loss.

The entire available for sale debt portfolio included $8.0 billion of securities that were in a loss position at June 30, 2024, compared to $9.6 billion at December 31, 2023.  The total amount of unrealized loss on these securities was $1.1 billion at June 30, 2024, a decrease of $144.4 million compared to the unrealized loss at December 31, 2023.  Securities with significant unrealized losses are discussed in the "Allowance for credit losses on available for sale debt securities" section above.

For debt securities classified as available for sale, the following table shows the amortized cost, fair value, and allowance for credit losses of securities available for sale at June 30, 2024 and December 31, 2023, and the corresponding amounts of gross unrealized gains and losses (pre-tax) in AOCI, by security type.

Net gains on investment securities for the six months ended June 30, 2024 were mainly comprised of net gains of $178.3 million on equity investments and net gains in fair value of $12.8 million recorded on private equity investments. These gains were largely offset by net losses of $187.5 million on sales of available for sale securities.

Subsequent to the successful close of the Exchange Offer in early May 2024, the Company approved and executed a plan to reposition a portion of its available for sale debt securities portfolio through the sale of securities with an amortized cost of $1.2 billion. The securities that the Company sold had a yield of approximately 2.1%, which resulted in a loss of $179.1 million, and the Company reinvested $928.8 million of the proceeds into U.S. Treasury securities yielding approximately 4.6%.

Pledged securities

At June 30, 2024, securities totaling $6.5 billion in fair value were pledged to secure public fund deposits, securities sold under agreements to repurchase, trust funds, and borrowings at the FRB and FHLB, compared to $7.5 billion at December 31, 2023. Except for obligations of various government-sponsored enterprises such as FNMA, FHLB and FHLMC, no investment in a single issuer exceeded 10% of stockholders’ equity.

Guarantees [Abstract]

Guarantees

Guarantees

The Company, as a provider of financial services, routinely issues financial guarantees in the form of financial and performance standby letters of credit. Standby letters of credit are contingent commitments issued by the Company generally to guarantee the payment or performance obligation of a customer to a third party. While these represent a potential outlay by the Company, a significant amount of the commitments may expire without being drawn upon. The Company has recourse against the customer for any amount it is required to pay to a third party under a standby letter of credit. The letters of credit are subject to the same credit policies, underwriting standards and approval process as loans made by the Company. Most of the standby letters of credit are secured, and in the event of nonperformance by customers, the Company has rights to the underlying collateral, which could include commercial real estate, physical plant and property, inventory, receivables, cash and marketable securities.

Upon issuance of standby letters of credit, the Company recognizes a liability for the fair value of the obligation undertaken, which is estimated to be equivalent to the amount of fees received from the customer over the life of the agreement. At June 30, 2024, that net liability was $3.6 million, which will be accreted into income over the remaining life of the respective commitments. The contractual amount of these letters of credit, which represents the maximum potential future payments guaranteed by the Company, was $633.6 million at June 30, 2024.

The Company periodically enters into credit risk participation agreements (RPAs) as a guarantor to other financial institutions, in order to mitigate those institutions’ credit risk associated with interest rate swaps with third parties. The RPA stipulates that, in the event of default by the third party on the interest rate swap, the Company will reimburse a portion of the loss borne by the financial institution. These interest rate swaps are normally collateralized (generally with real property, inventories and equipment) by the third party, which limits the credit risk associated with the Company’s RPAs. The third parties usually have other borrowing relationships with the Company. The Company monitors overall borrower collateral and at June 30, 2024, believes sufficient collateral is available to cover potential swap losses. The RPAs are carried at fair value throughout their term with all changes in fair value, including those due to a change in the third party’s creditworthiness, recorded in current earnings. The terms of the RPAs, which correspond to the terms of the underlying swaps, range from 2 years to 15 years. At June 30, 2024, the fair value of the Company's guarantee liabilities for RPAs was $83 thousand, and the notional amount of the underlying swaps was $455.7 million. The maximum potential future payment guaranteed by the Company cannot be readily estimated but is dependent upon the fair value of the interest rate swaps at the time of default.

Leases

The Company has net investments in direct financing and sales-type leases to commercial, industrial, and tax-exempt entities. These leases are included within business loans on the Company's consolidated balance sheets. The Company primarily leases various types of equipment, trucks and trailers, and office furniture and fixtures. Lease agreements may include options for the lessee to renew or purchase the leased equipment at the end of the lease term. The Company has elected to adopt the lease component expedient in which the lease and nonlease components are combined into the total lease receivable. The Company also leases office space to third parties, and these leases are classified as operating leases. The leases may include options to renew or expand the leased space, and currently the leases have remaining terms of 1 month to 14 years.

The following table provides the components of lease income.

Common Stock

Common Stock *

Presented below is a summary of the components used to calculate basic and diluted income per share. The Company applies the two-class method of computing income per share, as nonvested share-based awards that pay nonforfeitable common stock dividends are considered securities which participate in undistributed earnings with common stock. The two-class method requires the calculation of separate income per share amounts for the nonvested share-based awards and for common stock. Income per share attributable to common stock is shown in the table below. Nonvested share-based awards are further discussed in Note 13.

Segment Reporting [Abstract]

Segments

Segments

The Company segregates financial information for use in assessing its performance and allocating resources among three operating segments: Consumer, Commercial and Wealth. The Consumer segment consists of various consumer loan and deposit products offered through its retail branch network of approximately 140 locations.  This segment also includes indirect and other consumer loan financing businesses, along with debit and credit card loan and fee businesses.  The Commercial segment provides corporate lending (including the Small Business Banking product line within the branch network), leasing, and international services, along with business and governmental deposit products and commercial cash management services.  This segment also includes both merchant and commercial bank card products as well as the Commercial Tradable Products division, which sells fixed income securities, underwrites municipal bonds, and provides securities safekeeping and accounting services to its business and correspondent bank customers.  The Wealth segment provides traditional trust and estate planning, advisory and discretionary investment management, and brokerage services.  This segment also provides various loan and deposit related services to its private banking customers.

The following table presents selected financial information by segment and reconciliations of combined segment totals to consolidated totals. There were no material intersegment revenues between the three segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. If appropriate, these changes are reflected in prior year information presented below. Net interest income allocated among the segments prior to 2024 has been restated to reflect a funds transfer pricing methodology change implemented on January 1, 2024 for all deposit types, except certificates of deposit. The new methodology moves from a rolling pool to a profitability range methodology. The new methodology more accurately reflects the profitability of affected deposits relative to current rates and removes most interest rate risk from business segments.

The information presented above was derived from the internal profitability reporting system used by management to monitor and manage the financial performance of the Company. This information is based on internal management accounting procedures and methods, which have been developed to reflect the underlying economics of the businesses. The methodologies are applied in connection with funds transfer pricing and assignment of overhead costs among segments. Funds transfer pricing was used in the determination of net interest income by assigning a standard cost (credit) for funds used (provided by) assets and liabilities based on their maturity, prepayment and/or repricing characteristics.

The segment activity, as shown above, includes both direct and allocated items. Amounts in the “Other/Elimination” column include activity not related to the segments, such as that relating to administrative functions, the investment securities portfolio, and the effect of certain expense allocations to the segments. The provision for credit losses in this category contains the difference between net loan charge-offs assigned directly to the segments and the recorded provision for credit loss expense. Included in this category’s net interest income are earnings of the investment portfolio, which are not allocated to a segment. Additionally, in 2023, interest expense on the Company's brokered certificates of deposit was included in this column, as the Company's brokered certificates of deposit were not allocated to a segment. There were no brokered certificates of deposit in 2024.

The performance measurement of the operating segments is based on the management structure of the Company and is not necessarily comparable with similar information for any other financial institution. The information is also not necessarily indicative of the segments' financial condition and results of operations if they were independent entities.

Derivative Instrument Detail [Abstract]

Derivative Instruments

Derivative Instruments

The notional amounts of the Company’s derivative instruments are shown in the table below. These contractual amounts, along with other terms of the derivative, are used to determine amounts to be exchanged between counterparties and are not a measure of loss exposure. The Company's derivatives are accounted for as freestanding derivatives, and with the exception of the interest rate floors, changes in their fair value are recorded in current earnings.

(In thousands)	June 30, 2024		December 31, 2023
Interest rate swaps	$	2,300,300	$	2,166,393
Interest rate floors	2,000,000		2,000,000
Interest rate caps	267,447		336,682
Credit risk participation agreements	676,506		653,887
Foreign exchange contracts	33,042		30,401
Mortgage loan commitments	7,252		3,004
Mortgage loan forward sale contracts	717		1,349
Forward TBA contracts	7,500		3,000
Total notional amount	$	5,292,764	$	5,194,716

The largest group of notional amounts relate to interest rate swap contracts sold to commercial customers who wish to modify their interest rate sensitivity. The customers are engaged in a variety of businesses, including real estate, manufacturing, retail product distribution, education, and retirement communities. These interest rate swap contracts with customers are offset by matching interest rate swap contracts purchased by the Company from other financial institutions (dealers). Contracts with dealers that require central clearing are novated to a clearing agency who becomes the Company's counterparty. Because of the matching terms of the offsetting contracts, in addition to collateral provisions which mitigate the impact of non-performance risk, changes in fair value subsequent to initial recognition have a minimal effect on earnings.

Many of the Company’s interest rate swap contracts with large financial institutions contain contingent features relating to debt ratings or capitalization levels. Under these provisions, if the Company’s debt rating falls below investment grade or if the Company ceases to be “well-capitalized” under risk-based capital guidelines, certain counterparties can require immediate and ongoing collateralization on interest rate swaps in net liability positions or instant settlement of the contracts. The Company maintains debt ratings and capital well above these minimum requirements.

As of June 30, 2024, the Company held four interest rate floors indexed to 1-month SOFR to hedge the risk of declining interest rates on certain floating rate commercial loans. The floors have a combined notional value of $2.0 billion and are forward-starting. Each of the four interest rate floors has a six-year term and a notional amount of $500.0 million. In the event that the index rate falls below zero, the maximum rate that the Company can earn on the notional amount of each floor is limited to the strike rate. Information about the floors is provided in the table below.

Strike Rate		Effective Date	Maturity Date
3.50	%	July 1, 2024	July 1, 2030
3.25	%	November 1, 2024	November 1, 2030
3.00	%	March 1, 2025	March 1, 2031
2.75	%	July 1, 2025	July 1, 2031

The premium paid for the floors totaled $90.2 million. The maximum length of time over which the Company is hedging its exposure to lower rates is approximately 7 years. These interest rate floors qualified and were designated as cash flow hedges and were assessed for effectiveness using regression analysis. The change in the fair value of these interest rate floors is recorded in AOCI, net of the amortization of the premiums paid, which are recorded against interest and fees on loans in the consolidated statements of income. As of June 30, 2024, net deferred losses on the interest rate floors totaled $25.8 million (pre-tax) and were recorded in AOCI in the consolidated balance sheet. As of June 30, 2024, it is expected that $10.7 million

(pre-tax) interest rate floor premium amortization will be reclassified from AOCI into earnings over the next 12 months for the outstanding interest rate floors.

During the year ended December 31, 2020, the Company monetized three interest rate floors that were previously classified as cash flow hedges with a combined notional balance of $1.5 billion and an asset fair value of $163.2 million. As of June 30, 2024, the total realized gains on the monetized cash flow hedges remaining in AOCI was $40.1 million (pre-tax), which will be reclassified into interest income over the next 2.5 years. The estimated amount of net gains related to the cash flow hedges remaining in AOCI at June 30, 2024 that is expected to be reclassified into income within the next 12 months is $21.2 million.

The Company also contracts with other financial institutions, as a guarantor or beneficiary, to share credit risk associated with certain interest rate swaps through risk participation agreements. The Company’s risks and responsibilities as guarantor are further discussed in Note 5 on Guarantees. In addition, the Company enters into foreign exchange contracts, which are mainly comprised of contracts with customers to purchase or deliver specific foreign currencies at specific future dates.

Under its program to sell residential mortgage loans in the secondary market, the Company designates certain newly-originated residential mortgage loans as held for sale. Derivative instruments arising from this activity include mortgage loan commitments and forward loan sale contracts. Changes in the fair values of the loan commitments and funded loans prior to sale that are due to changes in interest rates are economically hedged with forward contracts to sell residential mortgage-backed securities in the to-be-announced (TBA) market. These forward TBA contracts are also considered to be derivatives and are settled in cash at the security settlement date.

The fair values of the Company's derivative instruments, whose notional amounts are listed above, are shown in the table below. Information about the valuation methods used to determine fair value is provided in Note 15 on Fair Value Measurements.

The Company's policy is to present its derivative assets and derivative liabilities on a gross basis on its consolidated balance sheets, and these are reported in other assets and other liabilities. In prior years, certain collateral posted to and from the Company's clearing counterparty has been applied to the fair values of the cleared swap. There was no reduction to positive or negative fair values of cleared swaps at June 30, 2024 and December 31, 2023.

The Company made an election to exclude the initial premiums paid on the interest rate floors from the hedge effectiveness measurement. Those initial premiums are amortized over the periods between the premium payment month and the contract maturity month. The pre-tax effects of the gains and losses (both the included and excluded amounts for hedge effectiveness assessment) recognized in the other comprehensive income from the cash flow hedging instruments and the amounts reclassified from accumulated other comprehensive income into income (both included and excluded amounts for hedge effectiveness measurement) are shown in the table below.

The following table shows the extent to which assets and liabilities relating to derivative instruments have been offset in the consolidated balance sheets. It also provides information about these instruments which are subject to an enforceable master netting arrangement, irrespective of whether they are offset, and the extent to which the instruments could potentially be offset. Also shown is collateral received or pledged in the form of other financial instruments, which is generally cash or marketable securities. The collateral amounts in this table are limited to the outstanding balances of the related asset or liability (after netting is applied); thus, amounts of excess collateral are not shown. Most of the derivatives in the following table were transacted under master netting arrangements that contain a conditional right of offset, such as close-out netting, upon default.

While the Company is party to master netting arrangements with most of its swap derivative counterparties, the Company does not offset derivative assets and liabilities under these agreements on its consolidated balance sheets. Collateral exchanged between the Company and dealer bank counterparties is generally subject to thresholds and transfer minimums, and usually consists of marketable securities. By contract, these may be sold or re-pledged by the secured party until recalled at a subsequent valuation date by the pledging party. For those swap transactions requiring central clearing, the Company posts cash or securities to its clearing agent. Collateral positions are valued daily, and adjustments to amounts received and pledged by the Company are made as appropriate to maintain proper collateralization for these transactions. Swap derivative transactions with customers are generally secured by rights to non-financial collateral, such as real and personal property, which is not shown in the table below.

The Company regularly enters into resale and repurchase agreement transactions with other financial institutions and with its own customers. Resale and repurchase agreements are agreements to purchase/sell securities subject to an obligation to resell/repurchase the same or similar securities. They are accounted for as secured lending and collateralized borrowing (e.g. financing transactions), not as true sales and purchases of the underlying collateral securities. Some of the resale and repurchase agreements were transacted under master netting arrangements that contain a conditional right of offset, such as close-out netting, upon default. The security collateral accepted or pledged in resale and repurchase agreements with other financial institutions may be sold or re-pledged by the secured party, but is usually delivered to and held by third party trustees. The Company generally retains custody of securities pledged for repurchase agreements with its customers.

The following table shows the extent to which resale agreement assets and repurchase agreement liabilities with the same counterparty have been offset on the consolidated balance sheets, in addition to the extent to which they could potentially be offset. Also shown is collateral received or pledged, which consists of marketable securities. The collateral amounts in the table are limited to the outstanding balances of the related asset or liability (after offsetting is applied); thus amounts of excess collateral are not shown.

Share-Based Payment Arrangement, Noncash Expense [Abstract]

Stock-Based Compensation

Stock-Based Compensation

The Company issues stock-based compensation in the form of nonvested restricted stock and stock appreciation rights (SARs). Historically, most of the awards have been issued during the first quarter of each year. The stock-based compensation expense charged against income was $4.2 million and $3.9 million in the three months ended June 30, 2024 and 2023 respectively, and $8.5 million and $8.3 million in the six months ended June 30, 2024 and 2023, respectively.

Nonvested stock awards granted generally vest in 4 to 7 years and contain restrictions as to transferability, sale, pledging, or assigning, among others, prior to the end of the vesting period. Dividend and voting rights are conferred upon grant. A summary of the status of the Company’s nonvested share awards as of June 30, 2024, and changes during the six month period then ended, is presented below.

	Shares	Weighted Average Grant Date Fair Value
Nonvested at January 1, 2024	1,166,335	$58.48
Granted	322,088	52.03
Vested	(250,127)	52.21
Forfeited	(27,582)	59.87
Nonvested at June 30, 2024	1,210,714	$58.03

SARs are granted with exercise prices equal to the market price of the Company’s stock at the date of grant. SARs vest ratably over 4 years of continuous service and have contractual terms of 10 years. All SARs must be settled in stock under provisions of the plan. In determining compensation cost, the Black-Scholes option-pricing model is used to estimate the fair value of SARs on date of grant. The current year per share average fair value and the model assumptions are shown in the table below.

Weighted per share average fair value at grant date	$14.88
Assumptions:
Dividend yield	2.1	%
Volatility	29.3	%

Revenue from Contracts with Customers

Revenue from contracts with customers, Accounting Standard Codification 606 ("ASC 606"), requires revenue recognition for the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. For the six months ended June 30, 2024, approximately 63% of the Company’s total revenue was comprised of net interest income, which is not within the scope of this guidance. Of the remaining revenue, those items that were subject to this guidance mainly included fees for bank card, trust, deposit account services and consumer brokerage services.

The following table disaggregates revenue from contracts with customers by major product line.

	Three Months Ended June 30				Six Months Ended June 30
(In thousands)	2024		2023		2024		2023
Trust fees	$	52,291	$	47,265	$	103,396	$	92,593

Total non-interest income	$	152,244	$	147,605	$	301,092	$	285,217

(1) This revenue is not within the scope of ASC 606, and includes fees relating to bond trading activities, loan fees and sales, derivative instruments, standby letters of credit and various other transactions.

For bank card transaction fees, nearly all of debit and credit card fees are earned in the Consumer segment, while corporate card and merchant fees are earned in the Commercial segment. The Consumer and Commercial segments contributed approximately 31% and 69%, respectively, of the Company's deposit account charge revenue. All trust fees and nearly all consumer brokerage services income were earned in the Wealth segment.    

The following table presents the opening and closing receivable balances for the six month periods ended June 30, 2024 and 2023 for the Company’s significant revenue from contracts with customers.

(In thousands)	June 30, 2024		December 31, 2023		June 30, 2023		December 31, 2022
Bank card transaction fees	$	15,824	$	18,069	$	16,321	$	17,254

Fair Value Measurements [Abstract]

Fair Value Measurements

Fair Value Measurements

The Company uses fair value measurements to record fair value adjustments to certain financial and nonfinancial assets and liabilities and to determine fair value disclosures. Various financial instruments such as available for sale debt securities, equity securities, trading debt securities, certain investments relating to private equity activities, and derivatives are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other assets and liabilities on a nonrecurring basis, such as mortgage servicing rights and certain other investment securities. These nonrecurring fair value adjustments typically involve lower of cost or fair value accounting or write-downs of individual assets.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Depending on the nature of the asset or liability, the Company uses various valuation techniques and assumptions when estimating fair value. For accounting disclosure purposes, a three-level valuation hierarchy of fair value measurements has been established. The valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability as of the measurement date. The three levels are defined as follows:

•Level 1 – inputs to the valuation methodology are quoted prices for identical assets or liabilities in active markets.

•Level 2 – inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, and inputs that are observable for the assets or liabilities, either directly or indirectly (such as interest rates, yield curves, and prepayment speeds).

•Level 3 – inputs to the valuation methodology are unobservable and significant to the fair value. These may be internally developed, using the Company’s best information and assumptions that a market participant would consider.

The valuation methodologies for assets and liabilities measured at fair value on a recurring and non-recurring basis are described in the Fair Value Measurements note in the Company's 2023 Annual Report on Form 10-K. There have been no significant changes in these methodologies since then.

Instruments Measured at Fair Value on a Recurring Basis

The table below presents the June 30, 2024 and December 31, 2023 carrying values of assets and liabilities measured at fair value on a recurring basis. There were no transfers among levels during the first six months of 2024 or the year ended December 31, 2023.

Fair Value Of Financial Instruments [Abstract]

Fair Value Of Financial Instruments

Fair Value of Financial Instruments

The carrying amounts and estimated fair values of financial instruments held by the Company are set forth below. Fair value estimates are made at a specific point in time based on relevant market information. They do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular financial instrument. Because no market exists for many of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, risk characteristics and economic conditions. These estimates are subjective, involve uncertainties, and cannot be determined with precision. Changes in assumptions could significantly affect the estimates.

The estimated fair values of the Company’s financial instruments and the classification of their fair value measurement within the valuation hierarchy are as follows at June 30, 2024 and December 31, 2023:

Summary Of Available For Sale Investment Securities By Maturity Groupings

A summary of the available for sale debt securities by maturity groupings as of June 30, 2024 is shown below. The investment portfolio includes agency mortgage-backed securities, which are guaranteed by agencies such as FHLMC, FNMA, and Government National Mortgage Association (GNMA), in addition to non-agency mortgage-backed securities, which have no guarantee but are collateralized by commercial and residential mortgages. Also included are certain other asset-backed securities, which are primarily collateralized by credit cards, automobiles, student loans, and commercial loans. These securities differ from traditional debt securities primarily in that they may have uncertain maturity dates and are priced based on estimated prepayment rates on the underlying collateral.

The table below summarizes debt securities available for sale in an unrealized loss position, aggregated by length of loss period, for which an allowance for credit losses has not been recorded at June 30, 2024 and December 31, 2023. Unrealized losses on these available for sale securities have not been recognized into income because after review, the securities were deemed not to be impaired.

Summary Of Components Used To Calculate Basic And Diluted Income Per Share

Presented below is a summary of the components used to calculate basic and diluted income per share. The Company applies the two-class method of computing income per share, as nonvested share-based awards that pay nonforfeitable common stock dividends are considered securities which participate in undistributed earnings with common stock. The two-class method requires the calculation of separate income per share amounts for the nonvested share-based awards and for common stock. Income per share attributable to common stock is shown in the table below. Nonvested share-based awards are further discussed in Note 13.

Segment Reporting [Abstract]

Schedule Of Financial Information By Segment

The following table presents selected financial information by segment and reconciliations of combined segment totals to consolidated totals. There were no material intersegment revenues between the three segments. Management periodically makes changes to methods of assigning costs and income to its business segments to better reflect operating results. If appropriate, these changes are reflected in prior year information presented below. Net interest income allocated among the segments prior to 2024 has been restated to reflect a funds transfer pricing methodology change implemented on January 1, 2024 for all deposit types, except certificates of deposit. The new methodology moves from a rolling pool to a profitability range methodology. The new methodology more accurately reflects the profitability of affected deposits relative to current rates and removes most interest rate risk from business segments.

Schedule of Derivative Instruments, Effect on Other Comprehensive Income (Loss)

The Company made an election to exclude the initial premiums paid on the interest rate floors from the hedge effectiveness measurement. Those initial premiums are amortized over the periods between the premium payment month and the contract maturity month. The pre-tax effects of the gains and losses (both the included and excluded amounts for hedge effectiveness assessment) recognized in the other comprehensive income from the cash flow hedging instruments and the amounts reclassified from accumulated other comprehensive income into income (both included and excluded amounts for hedge effectiveness measurement) are shown in the table below.
