NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

March 31, 2026 (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). Effective January 1, 2026, the consolidated financial statements also include the accounts of FineMark Holdings, Inc. ("FineMark"), which was acquired by the Company as described in Note 2 "Acquisition" below, and is consolidated from the date of acquisition. 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 2025 data to conform to current year presentation, and certain balances related to the FineMark Holdings, Inc. acquisition were reclassified to conform to the Company's financial statement 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 three month period ended March 31, 2026 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.

The Company adopted ASU 2025-08 "Financial Instruments - Credit Losses (Topic 326): Purchased Loans" on January 1, 2026. This new guidance makes significant changes to the accounting for certain acquired seasoned loans subject to the current expected credit loss model (CECL). Under the ASU, the initial allowance for credit losses recorded upon the acquisition of loans in scope is recognized as an adjustment to the amortized cost basis of the loan - similar to the model for purchased credit deteriorated assets. For these loans, the "day-one" credit loss estimate does not impact earnings immediately but is instead amortized over time as an adjustment to interest income. Subsequent changes in the allowance for credit losses are reported in earnings within provision for credit losses.

The following significant accounting policies have been updated or added since the Company's 2025 Annual Report on Form 10-K to reflect the adoption of ASU 2025-08.

Acquired loans - Purchased Credit Deteriorated

Loans acquired in a business combination are recognized on the acquisition date at their estimated fair value based on expected future cash flows discounted at a market-based rate of interest and inclusive of adjustments for credit risk, interest rate risk, liquidity, and other factors. Acquired loans that have experienced more-than-insignificant deterioration in credit quality since origination are classified as purchased credit deteriorated ("PCD") loans. An allowance for credit losses is established for the initial estimate of expected credit losses on PCD loans as of the acquisition date and recorded through a gross-up adjustment to the loan’s amortized cost basis.

Acquired loans - Purchased Seasoned Loans

Non-PCD loans acquired in a business combination are deemed purchased seasoned loans with an allowance for credit losses established for the initial estimate of expected credit losses as of the acquisition date and recorded through a gross-up adjustment to the loans’ amortized cost basis. See Note 2 “Acquisition” for additional information on loans acquired in a business combination.

2. Acquisition

On January 1, 2026, the Company completed its previously announced acquisition of FineMark Holdings, Inc., a bank holding company headquartered in Fort Myers, Florida, pursuant to the Agreement and Plan of Merger dated June 16, 2025. Immediately after the Merger, FineMark's wholly-owned subsidiary, FineMark National Bank & Trust, merged into the Bank, with the Bank continuing as the surviving bank.

Total purchase consideration for the acquisition was $519.9 million, consisting of 9.9 million shares of the Company's common stock (valued at the acquisition-date fair value of $52.34 per share), plus cash in lieu of fractional shares. Prior to the acquisition date, the Company held a non-controlling equity interest in FineMark, and in accordance with ASC 805, this previously held interest was remeasured to its acquisition-date fair value of $4.6 million. The total acquisition-date fair value of the business combination was $524.5 million, comprised of the $519.9 million of consideration transferred and the $4.6 million fair value of the Company's previously held equity interest.

Under the terms of the merger agreement, each outstanding FineMark common stock share was converted into .7245 shares of the Company's common stock, and each outstanding share of FineMark's preferred stock was converted into 36.3636 shares of FineMark common stock, prior to conversion into .7245 shares of the Company's common stock.

The acquisition of FineMark was accounted for as a business combination using the purchase method of accounting in accordance with FASB ASC Topic 805, Business Combinations, which requires assets acquired and liabilities assumed to be recognized at fair value as of the acquisition date. The valuation of assets acquired and liabilities assumed has not yet been finalized. The determination of fair value requires management to make estimates related to discount rates, expected future cash flows, market conditions and other future events that are highly subjective in nature and subject to change. Any necessary adjustments from preliminary estimates must be finalized within one year from the closing date of the acquisition. Measurement period adjustments will be recorded in the period in which they are determined, as if they had been completed at the acquisition date. Valuations subject to refinement include, but are not limited to, loans, certain deposits, the core deposit, customer relationship, trade name intangible assets, and certain other assets.

The following table provides the preliminary allocation of the purchase consideration to the assets acquired and liabilities assumed from FineMark as of January 1, 2026:

Other liabilities	25,298
Total liabilities assumed	$	3,549,295

Preliminary fair value of net assets acquired	$	417,221
Preliminary goodwill	107,266

In connection with the acquisition, the Company recorded preliminary goodwill of $107.3 million, none of which is expected to be deductible for tax purposes. The preliminary goodwill is attributable to expected synergies and other factors to arise from the transaction. Information regarding the allocation of goodwill to the Company’s reportable segments as a result of the acquisition, as well as the carrying amounts and amortization of core deposit and other intangible assets, are provided in Note 5 "Goodwill and Other Intangible Assets" in the Notes to Consolidated Financial Statements.

Loans

Fair values for loans were based on a discounted cash flow methodology that considered factors including the type of loan and related collateral, classification status, fixed or variable interest rate and prepayment rate, term, amortization status and current discount rates. Loans were grouped together according to similar characteristics when applying various valuation techniques. The discount rates used for loans were based on current market rates for new originations of comparable loans include adjustments for liquidity. The discount rate does not include a factor for credit losses as that has been included as a reduction to the estimated cash flows. Purchased loans that reflect a more-than-insignificant deterioration of credit from origination are considered purchased credit deteriorated ("PCD"). For PCD loans, the initial estimate of expected credit losses is recognized in the allowance for credit losses on loans on the date of acquisition using the same methodology as other loans held-for-investment. The Company adopted ASU 2025-08 "Financial Instruments - Credit Losses (Topic 326): Purchased Loans" as of January 1, 2026. Accordingly, the initial estimate of expected credit losses recognized in the allowance for credit losses on loans included both PCD and non-PCD loans ("purchased seasoned loans").

The following table includes the fair value and unpaid principal balance of the acquired loans as of January 1, 2026:


(In thousands)	Unpaid principal balance		Premium / (discount)		Loans		Allowance for credit losses		Net loans
Purchased seasoned loans	$	2,351,772	$	(76,873)	$	2,274,899	$	(19,870)	$	2,255,029
PCD loans	368,533		(12,738)		355,795		(2,958)		352,837

Table of Contents

Investment securities

The investment securities acquired by the Company were classified by the Company as trading securities and were valued utilizing the actual sale prices for those securities, as all were sold promptly after the completion of the acquisition.

Interest earning deposits with banks and Cash and due from banks

The carrying amount of these assets was a reasonable estimate of fair value based on the short-term nature of these assets.

Core deposit intangible asset

Core deposit intangibles represent the value of relationships with deposit clients and the cost savings derived from available core deposits relative to an alternative funding source. The fair value of the core deposit intangible was estimated using a net cost savings method, a variation of the income approach. This approach considers expected client attrition rates, average life and balance inflation, alternative cost of funds, the interest cost and net maintenance cost associated with the client deposit base, and a discount rate used to discount the future economic benefits of the core deposit intangible asset to present value The core deposit intangible asset is being amortized using an accelerated methodology over 12 years based upon the period over which the estimated economic benefits are estimated to be received.

Customer relationship intangible asset

The fair value of the customer relationship intangible asset was determined using an income-based valuation approach, specifically the multi-period excess earnings method. The valuation reflects the present value of expected future cash flows derived from the acquired customer base, after considering expected customer attrition rates, projected earnings, contributory asset charges, and a discount rate reflecting market participant assumptions. The customer relationship intangible asset is being amortized using an accelerated methodology over 12 years based upon the period over which the estimated economic benefits are estimated to be received.

Deposits

The fair value for demand and savings deposits is the amount payable on demand at the acquisition date. The fair value for time deposits was valued using a discounted cash flow calculation that applied interest rates currently being offered to the contractual interest rates on such time deposits.

Other borrowings

The Company assumed FHLB debt of $351.5 million in its acquisition of FineMark and repaid that debt in January 2026. The fair value of FHLB debt assumed was valued using the actual payoff value as provided by the FHLB on January 1, 2026.

The results of FineMark are included in the results of the Company subsequent to the January 1, 2026. Transaction costs incurred after the acquisition date totaled $14.0 million, primarily in salaries and employee benefits and professional and other services in the Consolidated Statements of Income. Additional transaction and integration costs will be expensed in future periods as incurred.

The following table presents pro forma combined information as if FineMark had been acquired on January 1, 2025. These results combine the historical results of FineMark into the Company’s consolidated statement of income, and while adjustments were made for the estimated impact of certain fair value adjustments and other acquisition-related activity, the results do not necessarily reflect the results of operations that would have occurred had the acquisition taken place on January 1, 2025. Furthermore, cost savings and other business synergies related to the acquisition are not reflected in the pro forma combined amounts.


		Pro Forma Combined Results
	For the Three Months Ended
(In thousands)		March 31, 2026		March 31, 2025
Total revenue *		$	468,428	$	455,698
Net Income		150,695		135,690

*Total revenue is comprised of net interest income and non-interest income.

The Company's results for the three months ended March 31, 2026 include the operating results of the acquired assets and assumed liabilities of FineMark subsequent to the acquisition on January 1, 2026. Due to the streamlining and integration of the operating activities into those of the Company post-acquisition, historical reporting for the former FineMark operations is impracticable, and thus disclosures of the revenue from the assets acquired and income before taxes are impracticable for the period subsequent to the acquisition.

3. Loans and Allowance for Credit Losses

Major classifications within the Company’s held for investment loan portfolio at March 31, 2026 and December 31, 2025 are as follows:

Accrued interest receivable totaled $78.9 million and $74.4 million at March 31, 2026 and December 31, 2025, respectively, and was included within other assets on the consolidated balance sheets. For the three months ended March 31, 2026, the Company wrote-off accrued interest by reversing interest income of $39 thousand and $1.6 million in the Commercial and Personal Banking portfolios, respectively. For the three months ended March 31, 2025, the Company reversed $112 thousand and $1.7 million in the Commercial and Personal Banking portfolios, respectively.

At March 31, 2026, loans of $3.7 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 $2.7 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 March 31, 2026 and December 31, 2025 are discussed below.


Key Assumption	March 31, 2026	December 31, 2025

Overall economic forecast	•Economy expected to slow but continue to expand •Slightly increased unemployment due to reduced hiring •Inflation remains elevated •Assumes conflict in the Middle East will deescalate in the near term	•Increased GDP due to expected increases in consumer spending •Stable unemployment •Higher rates and volatility are expected to continue

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 •Loans downgraded to special mention, substandard, or non-accrual status •Auto, other vehicle and other consumer portfolios loss expectation adjustment •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 industries experiencing stress or emerging concerns within the portfolio •Loans downgraded to special mention, substandard, or non-accrual status •Auto, other vehicle and other consumer portfolios loss expectation adjustment •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 includes projections on inflation, labor market trends, Federal Reserve monetary policy, business growth, and consumer spending. 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 forecast assumes the conflict in the Middle East will de-escalate within the upcoming months and inflation trends are due to related higher energy prices. Uncertainty around increased unemployment and other negative economic trends is heightened.

Table of Contents

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 months ended March 31, 2026 and 2025, 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 March 31, 2026 and December 31, 2025 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 March 31, 2026 and December 31, 2025.

Modifications for borrowers experiencing financial difficulty

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 March 31, 2026 of loans that were modified during the three months ended March 31, 2026 and the amortized cost at March 31, 2025 of loans that were modified during the three months ended March 31, 2025.

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 months ended March 31, 2026 and March 31, 2025.

The Company had commitments of $13.3 million and $11.4 million at March 31, 2026 and December 31, 2025, 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 March 31, 2026 of loans to borrowers experiencing financial difficulty that had a payment default during the three months ended March 31, 2026 and were modified within the 12 months preceding the payment default, as well as the amortized cost basis at March 31, 2025 of loans to borrowers experiencing financial difficulty that had a payment default during the three months ended March 31, 2025 and had been modified within the 12 months preceding the payment default. 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 12. The loans are primarily sold to Federal Home Loan Mortgage Corporation (FHLMC) and Federal National Mortgage Association (FNMA). At March 31, 2026, the fair value of these loans was $1.7 million, and the unpaid principal balance was $1.6 million.

At March 31, 2026, 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 $678 thousand and $1.2 million at March 31, 2026 and December 31, 2025, respectively, and included in those amounts were $678 thousand and $1.0 million at March 31, 2026 and December 31, 2025, respectively, of foreclosed residential real estate properties held as a result of obtaining physical possession. Personal property acquired in repossession, generally autos, totaled $2.8 million and $2.3 million at March 31, 2026 and December 31, 2025. 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.

(1)Accrued interest receivable totaled $36.4 million and $42.0 million at March 31, 2026 and December 31, 2025, 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 liquidity management 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 mutual funds and common 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, 2026, this portfolio included the Company’s 411,723 shares of Visa Inc. (“Visa”) Class B-2 common stock, which are held by Commerce Bancshares, Inc. and were acquired by participating in a public exchange offer by Visa in 2024 (2024 Exchange Offer). At March 31, 2026, the Company’s Visa Class B-2 shares are carried at cost, which is $0, as the Company elected the measurement alternative approach for these shares and there have not been 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.

As a condition of participating in the 2024 Exchange Offer, the Company entered into a Makewhole Agreement (2024 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 had been effectively indemnified by Visa USA members through reductions to the conversion ratio for its Class B-1 common stock. The purpose of the 2024 Makewhole Agreement was 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.

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 March 31, 2026 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.

Investments in U.S. government and federal agency obligations include U.S. Treasury inflation-protected securities, which totaled $380.7 million, at fair value, at March 31, 2026. 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 March 31, 2026, the fair value of securities on this watch list was $970.5 million compared to $896.7 million at December 31, 2025. Almost all of the securities included on the Company's watch list in the current quarter were experiencing unrealized loss positions due to the increase in interest rates since their purchase and were analyzed outside of the cash flow model. At March 31, 2026, 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 March 31, 2026, the Company did not identify any securities for which a credit loss exists, and for the three

months ended March 31, 2026 and 2025, 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 March 31, 2026 and December 31, 2025. 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 March 31, 2026, 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.

6. 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 March 31, 2026, that net liability was $4.4 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 $682.6 million at March 31, 2026.

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 March 31, 2026, 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 1 to 11 years. At March 31, 2026, the fair value of the Company's guarantee liabilities for RPAs was $58 thousand, and the notional amount of the underlying swaps was $271.2 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.

7. 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 3 months to 13 years.

The following table provides the components of lease income.


	For the Three Months Ended March 31
(in thousands)		2026		2025
Direct financing and sales-type leases		$	10,130	$	9,843

9. 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 restricted stock 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 restricted stock 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 14.

Weighted average diluted common shares outstanding		145,857		139,725
Diluted income per common share		$	.96	$	.93

Unexercised stock appreciation rights of 439 thousand and 167 thousand for the three month periods ended March 31, 2026 and 2025, respectively, were excluded from the computation of diluted income per common share because their inclusion would have been anti-dilutive. Nonvested time-vested restricted stock units of 42 thousand for the three month period ended March 31, 2026 were excluded from the computation of diluted income per common share because their inclusion would have been anti-dilutive.

* All prior year share and per share amounts in this note have been restated for the 5% common stock dividend distributed in December 2025.

11. Segments

The Company segregates financial information for use in assessing its performance and allocating resources among three operating segments: Retail Banking, Commercial and Wealth. The Retail Banking segment consists of various consumer loan and deposit products offered through its retail branch network of approximately 150 locations. This segment also includes residential mortgage, 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 Company’s chief executive officer is its chief operating decision maker ("CODM"). The CODM is the primary individual in control of resource allocation, and the allocation determinations are made in consultation with the Company’s executive management committee, of which the CODM is a member. The Company’s CODM primarily utilizes net income before taxes to evaluate each segment’s performance and allocate resources (including employees, financial, or capital resources), primarily through the Company’s annual budgeting process and periodic segment performance reviews. To manage operations and make decisions regarding resource allocations, the CODM is regularly provided and reviews total non-interest expense at a consolidated level and total non-interest expense for each segment.

Table of Contents

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.

Non-interest expense for the Retail Banking, Commercial, and Wealth segments above is primarily comprised of salaries, incentives, benefits, and allocated overhead costs for service and support. Non-interest expense for the segments also includes expense for data processing and software, occupancy, and professional and other services.

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.

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.

12. 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 not accounted for as accounting hedges except for the interest rate floors and one interest rate swap, as discussed below.

Interest rate swap contracts are 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.

At March 31, 2026, the Company had one interest rate swap with a notional amount of $100.0 million, which is designated as a fair value hedge of certain variable rate loans. This swap was acquired during the Company's acquisition of FineMark. Gains and losses on the derivative instrument, as well as the offsetting loss or gain on the hedged loans attributable to the hedged risk, are recognized in current earnings. These gains and losses are reported in interest and fees on loans in the accompanying consolidated statements of income. The table below shows gains and losses related to fair value hedges.

As of March 31, 2026, the Company held five 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 $2.5 billion. Each of the five 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

The premium paid for the floors totaled $102.2 million, including $11.9 million during the quarter ended March 31, 2026. At March 31, 2026, the maximum length of time over which the Company is hedging its exposure to lower rates is

approximately 6.5 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 March 31, 2026, net deferred losses on the interest rate floors totaled $24.9 million (pre-tax) and were recorded in AOCI in the consolidated balance sheet. As of March 31, 2026, it is expected that $14.0 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 March 31, 2026, the total realized gains on the monetized cash flow hedges remaining in AOCI was $5.6 million (pre-tax), which will be reclassified into interest income over the next 9 months. The estimated amount of net gains related to the cash flow hedges remaining in AOCI at March 31, 2026 that is expected to be reclassified into income within the next 12 months is $5.6 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 6 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 16 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 March 31, 2026 and December 31, 2025.

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.

13. 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.

Table of Contents

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.

14. Stock-Based Compensation

In accordance with the requirements of ASC 718-10-30-3 and 35-2, the Company measures the cost of stock-based compensation based on the grant-date fair value of the award, recognizing the cost over the requisite service period, which is generally the vesting period.

Beginning February 2026, the Company issued stock-based compensation in the form of time-vested restricted stock units (RSUs) and performance-vested restricted stock units (PSUs). The fair value of a PSU is estimated using a Monte Carlo simulation analysis while the fair value of a RSU is the common stock (CBSH) market price. Compensation expense for PSUs is recognized over the requisite service period based on the probable outcome of the performance conditions. RSUs and PSUs accrue forfeitable dividend equivalents which are paid in cash upon vesting. Dividend equivalents are included in compensation expense over the requisite service period. Prior to February 1, 2026, the Company issued stock-based compensation in the form of nonvested restricted stock awards and stock appreciation rights (SARs). The fair value of stock appreciation rights is estimated using the Black-Scholes option-pricing model while the fair value of a nonvested restricted stock award is the common stock (CBSH) market price. The expense recognized for stock-based compensation is included in salaries and employee benefits expense in the accompanying consolidated statements of income. The Company recognizes forfeitures as a reduction to expense only when they have occurred.

Historically, most of the awards have been issued during the first quarter of each year. Total stock-based compensation expense charged against income was $6.2 million and $4.4 million in the three months ended March 31, 2026 and 2025, respectively.

Restricted Stock Awards

Nonvested restricted 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 March 31, 2026, and changes during the three month period then ended, is presented below.


	Shares	Weighted Average Grant Date Fair Value
Nonvested at January 1, 2026	1,305,978	$55.11
Granted	206,153	53.81
Vested	(218,418)	57.12
Forfeited	(9,476)	53.44

Nonvested at March 31, 2026	1,284,237	$54.57

Time-Vested Restricted Stock Units and Performance-Vested Restricted Stock Units

RSUs generally vest after 3 to 4 years of continued service. PSUs are granted to key executives and vest at the end of a 3-year performance period. The number of shares ultimately earned is determined based on relative performance compared to peers over the performance period of the following equally weighted measures: Adjusted Return on Average Equity and Diluted EPS Growth. The earned PSU shares are further adjusted by a market condition modifier based on the Company's Total Shareholder Return relative to peers measured 3 years from the date of grant. RSUs and PSUs earn forfeitable cash dividend equivalents, which are paid in cash at the end of the vesting period, but do not carry voting rights.

The fair value of RSUs are based on the closing common stock (CBSH) market price on the date of grant. To measure the probability distribution of performance of the market condition, the fair value of PSUs are estimated based on a Monte Carlo simulation analysis. The Company engages a third-party valuation expert to perform the Monte Carlo simulation, and the assumptions used are shown in the table below.

Stock Appreciation Rights

Stock appreciation rights (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.

A summary of SAR activity during the first three months of 2026 is presented below.

15. 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 three months ended March 31, 2026, 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 March 31
(In thousands)		2026		2025
Trust fees		$	71,049	$	56,592
Bank card transaction fees		45,585		45,593

Other non-interest income (1)		11,453		10,966
Total non-interest income		$	175,851	$	158,949

(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 debit and credit card fees were earned in the Retail Banking segment, while corporate card and merchant fees were earned in the Commercial segment. The Retail Banking and Commercial segments contributed approximately 28% and 72%, 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 three month periods ended March 31, 2026 and 2025 for the Company’s significant revenue from contracts with customers.


(In thousands)	March 31, 2026		December 31, 2025		March 31, 2025		December 31, 2024
Bank card transaction fees	$	14,331	$	16,878	$	14,538	$	17,754

Deposit account charges and other fees	7,667		8,414		7,549		7,897

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.

16. 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 2025 Annual Report on Form 10-K. There have been no significant changes in these methodologies since then.

17. 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 March 31, 2026 and December 31, 2025:

18. Legal and Regulatory Proceedings

The Company has various legal proceedings pending at March 31, 2026, arising in the normal course of business. While some matters pending against the Company specify damages claimed by plaintiffs, others do not seek a specified amount of damages or are at early stages of the legal process. The Company records a loss accrual for all legal and regulatory matters for which it deems a loss is probable and can be reasonably estimated. Some matters, which are in the early stages, have not yet progressed to the point where a loss amount can be determined to be probable and estimable.

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 2025 Annual Report on Form 10-K. Results of operations for the three months ended March 31, 2026 are not necessarily indicative of results to be attained for any other period.

Acquisition

On January 1, 2026, the Company completed its previously announced acquisition of FineMark Holdings, Inc. ("FineMark"), a bank holding company headquartered in Fort Myers, Florida, pursuant to the Agreement and Plan of Merger dated June 16, 2025. Immediately after the merger, FineMark's wholly-owned subsidiary, FineMark National Bank & Trust, merged into the Bank, with the Bank continuing as the surviving bank. The acquisition added total assets of approximately $3.9 billion, including loans of $2.7 billion, total deposits of $3.1 billion, and assets under administration of $8.7 billion, as well as 13 banking offices in Florida, Arizona and South Carolina.

Visa Class B-2 common shares exchange offer

On April 13, 2026, Visa, Inc. (“Visa”) announced the commencement of a public offering to exchange Class B-2 common stock for a combination of shares of Class B-3 common stock and Class C common stock (“2026 Exchange Offer”). The Company tendered all of its Visa Class B-2 shares and is awaiting notification of acceptance of that tender and the closing of the 2026 Exchange Offer. If the Company’s tendered shares are accepted and the exchange occurs in the second quarter of 2026, the Company expects to record a significant gain during the second quarter of 2026 based on the conversion privilege of the Class C common stock and the closing price of Visa Class A common stock. A full description of the terms of the 2026 Exchange Offer is set forth in Visa’s related Issuer Tender Offer Statement on Schedule TO and Prospectus, each dated April 6, 2026, publicly filed with the U. S. Securities and Exchange Commission.

As described in Note 4 "Investment Securities," the Company previously entered into a Makewhole Agreement with Visa related to its participation in the 2024 Exchange Offer. In order to continue preserving the economic benefit of those same adjustments for Visa's Class A and Class C common stockholders in relation to the Class B-2 and Class B-3 conversion ratios following the 2026 Exchange Offer, and as a condition of participating in the 2026 Exchange Offer, the Company entered into a Makewhole Agreement (2026 Makewhole Agreement) with Visa that provides for similar cash payments to Visa under the same circumstances as described above for the 2024 Makewhole Agreement. As further described in Visa’s related Issuer Tender Offer Statement on Schedule TO and Prospectus, each dated April 13, 2026, publicly filed with the U. S. Securities and Exchange Commission, both the 2026 Makewhole Agreement and the related escrow fund and transfer restrictions on Visa’s Class B-2 common stock and the new Class B-3 common stock will terminate whenever the covered litigation is ultimately resolved, at which future date outstanding shares of Visa Class B-3 common stock will be convertible into shares of its Class A common stock at the then-applicable conversion ratio. The 2026 Makewhole Agreement also includes limited transfer restrictions, such that the Company may only transfer up to one-third of the shares of Visa Class C common stock received in the exchange within the first 45 days following the 2026 Exchange Offer acceptance date, and may only transfer up to two-thirds of the Class C common stock received within the first 90 days following the 2026 Exchange Offer acceptance date.

Additionally, if the Company’s tendered shares are accepted and the exchange occurs in the second quarter of 2026, the Company may consider a plan to reposition a portion of its available for sale debt securities portfolio through the sale of securities, which may result in a significant loss during the second quarter of 2026. The timing and amount of the loss ultimately realized on the available for sale debt securities and the reinvestment assumptions may depend on many considerations, including market conditions, the amount of the gain recognized on the conversion privilege of the Visa shares, and other factors.

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

Table of Contents

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 principle;, estimates made on income taxes; competition with other entities that offer financial services; cybersecurity threats; risks related to the merger with FineMark including, among others, (i) the Company's ability to promptly and effectively integrate the merger, (ii) diversion of management’s attention from ongoing business operations and opportunities, (iii) cost savings and any revenue synergies from the merger may not be fully realized or may take longer than anticipated to be realized, (iv) deposits attrition, customer or employee loss and/or revenue loss as a result of the merger, and (v) expenses related to the merger being greater than expected; 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 2025 Annual Report on Form 10-K and Part II, Item 1A. - "Risk Factors" in this report.

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 2025 Annual Report on Form 10-K. There have been no changes in the Company's application of critical accounting policies since December 31, 2025.

(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.

(net income) amounted to $141.6 million, an increase of $10.0 million, or 7.6%, compared to the first quarter of the previous year. For the current quarter, the annualized return on average assets was 1.62%, the annualized return on average equity was 13.22%, and the efficiency ratio was 60.00%.

Compared to the first quarter of last year, net interest income increased $30.7 million, or 11.4%, mainly due to increases in interest income on loans and securities purchased under agreements to resell (“resale agreements”) of $34.2 million and $1.0 million, respectively, partly offset by a decrease in interest income on investment securities of $4.2 million. Interest expense on deposits increased $4.1 million, while interest expense on borrowings decreased $2.7 million. The provision for credit losses decreased $3.5 million compared to the same quarter in the prior year. Non-interest income increased $16.9 million, or 10.6%, compared to the first quarter of 2025, mainly due to increases in trust fees, deposit account fees and brokerage fees of $14.5 million, $2.0 million and $659 thousand, respectively. Net gains on investment securities totaled $11.6 million in the current quarter compared to net losses of $7.6 million in the same quarter of last year. Securities gains in the current quarter primarily resulted from net gains in fair value of $10.9 million recorded on private equity investments. Non-interest expense increased $52.8 million, or 22.1%, over the first quarter of 2025, mainly due to higher salaries and benefits expense of $27.7 million, primarily a result of onboarding FineMark team members and acquisition-related compensation payments. Professional and other services expense increased $8.8 million, which included $4.7 million in acquisition-related legal and professional services expense. Other non-interest expense increased $6.4 million, primarily due an increase of $5.4 million in intangible amortization expense related to the FineMark acquisition. Data processing expense expense increased $5.1 million compared to the same quarter of last year.

Net interest income in the first quarter of 2026 was $299.8 million, an increase of $30.7 million over the first quarter of 2025. On a fully taxable-equivalent (FTE) basis, net interest income totaled $302.2 million in the first quarter of 2026, up $30.8 million over the same period last year and up $16.4 million over the previous quarter. The increase in net interest income

Table of Contents

compared to the first quarter of 2025 was mainly due to an increase in average loan balances in connection with the acquisition of FineMark on January 1, 2026. Accretion income on FineMark's loans resulting from purchase accounting adjustments totaled $6.9 million. Interest income earned on loans (FTE) increased over the same period in the prior year mainly due to higher average loan balances, partly offset by lower average rates earned. The decrease in total interest earned on investment securities (FTE) was mainly the result of lower average rates earned on U.S. government and federal agency obligations and lower average balances of asset-backed and mortgage-backed securities. The increase in deposit interest expense was mainly due to higher average balances, partly offset by lower average rates paid. Interest expense on securities sold under agreements to repurchase decreased mainly due to lower average rates paid. The Company's net yield on earning assets (FTE) was 3.59% in the current quarter compared to 3.56% in the first quarter of 2025.

Total interest income (FTE) increased $32.2 million over the first quarter of 2025. Interest income on loans (FTE) was $290.3 million during the first quarter of 2026, an increase of $34.3 million, or 13.4%, over the same quarter last year. The increase in loan interest income over the same quarter of last year was primarily due to growth of $3.1 billion, or 18.0%, in average loan balances and higher average rates earned on personal real estate loans. Most of the increase in interest income was due to the acquisition of FineMark, which added $2.7 billion in loan balances. The largest increase to interest income occurred in personal real estate loan interest, which grew $20.4 million due to a $1.4 billion, or 45.0%, increase in average balances coupled with a 54 basis point increase in the average rate earned. Revolving home equity loan interest income increased $4.6 million mainly due to a $252.4 million, or 70.4%, increase in average balances. Business real estate loan interest income increased $4.2 million due to higher average balances of $377.8 million, or 10.3%, partly offset by a decrease of 13 basis points in the average rate earned. The $3.6 million increase in consumer loan interest income was due to a $339.2 million, or 16.3%, increase in average balances, partly offset by a decline of 32 basis points in the average rate earned. Business loan interest income grew $2.6 million due to higher average balances of $580.9 million, or 9.5%, partly offset by a 34 basis point decrease in the average rate earned. Interest income on construction and land loans increased $402 thousand mainly due to growth in average balances of $177.0 million, or 12.5%, partly offset by a 71 basis point decrease in the average rate earned. These increases in interest income were slightly offset by a decrease in consumer credit card loan interest income of $1.3 million mainly due to an 85 basis point decrease in the average rate earned.

Interest income on investment securities (FTE) was $72.8 million during the first quarter of 2026, which was a decrease of $4.3 million from the same quarter last year. The largest decreases in interest income occurred in interest earned on asset-backed and mortgage-backed securities, which declined $2.9 million and $2.6 million, respectively. Interest income earned on asset-backed securities declined due to a $454.5 million decrease in average balances, partly offset by a 34 basis point increase in the average rate earned. A decrease of $577.0 million, or 12.1%, in average balances led to the decline in interest income on mortgage-backed securities. In addition, the Company recorded a $940 thousand adjustment to premium amortization at March 31, 2026, which increased interest income and reflected slower forward prepayment speed estimates on mortgage-backed securities. This increase was higher than the $539 thousand adjustment increasing income in the same quarter last year. These decreases to interest income were partly offset by growth of $2.3 million in interest income on U.S. government and federal agency obligations, driven by higher average balances of $603.9 million, or 23.3%, partly offset by a decline of 49 basis points in the average rate earned. 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), decreased $3.1 million from the same quarter last year. The average balance of the total investment portfolio (excluding unrealized fair value adjustments on available for sale debt securities) was $9.9 billion in the first quarter of 2026 and $10.5 billion in the first quarter of 2025.

Interest income on securities purchased under agreements to resell increased $1.0 million over the same quarter last year, due to an increase of 22 basis points in the average rate earned and growth of $61.1 million in the average balance. Interest income on deposits at the Federal Reserve increased $1.1 million due to an increase of $608.8 million in the average balance, partly offset by a decline of 76 basis points in the average rate earned.

The average fully taxable-equivalent yield on total interest earning assets was 4.74% in the first quarter of 2026, down from 4.81% in the first quarter of 2025.

Total interest expense increased $1.4 million compared to the first quarter of 2025 due an increase of $4.1 million in interest expense on interest bearing deposits, partly offset by a decrease of $2.7 million in interest expense on borrowings. The increase in deposit interest expense was primarily due to the acquisition of FineMark, which added $2.7 billion in interest bearing deposit balances. Compared to the same quarter last year, interest expense on interest checking and money market deposit balances increased $6.1 million due to growth of $2.1 billion, or 15.2%, in average balances, partly offset by a four basis point decline in the average rate paid. Interest expense on certificate of deposit accounts decreased $2.1 million due to a 56 basis point decline in average rates paid, partly offset by an increase of $144.8 million, or 6.1%, in average balances. The overall rate paid on total deposits decreased 11 basis points from the same quarter last year. Interest expense on customer repurchase agreements decreased $3.4 million due to a 47 basis point decline in the average rate paid and a decrease of $48.7 million, or

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 2025 Annual Report on Form 10-K.

Net loan charge-offs in the first quarter of 2026 amounted to $15.0 million, compared to $9.9 million in the prior quarter and $10.8 million in the first quarter of last year. Compared to the same period last year, net loan charge-offs in the first quarter of 2026 increased $4.2 million, and increased $5.1 million from the previous quarter. The increase from the prior year was mainly driven by an increase of $5.0 million in business real estate loan net charge-offs, offset by a decrease of $1.1 million in consumer loan net charge-offs. The increase in net loan charge-offs for the three months ended March 31, 2026 from the previous quarter was driven by increases of $5.4 million and $651 thousand in net charge-offs on business real estate and consumer credit card loans, respectively, partially offset by a decrease of $730 thousand in net charge-offs on consumer loans.

Table of Contents

For the three months ended March 31, 2026, annualized net charge-offs on average consumer credit card loans were 5.21%, compared to 4.55% in the previous quarter and 5.04% in the same period last year. Consumer loan annualized net charge-offs in the current quarter amounted to .30%, compared to .45% in the prior quarter and .56% in the same period last year. In the first quarter of 2026, total annualized net loan charge-offs were .30%, compared to .22% in the previous quarter and .25% in the same period last year.

For the three months ended March 31, 2026, the provision for credit losses on loans was $11.3 million, which was a decrease of $2.4 million from the provision recorded in the prior quarter. Compared to the same period in the prior year, the provision for credit losses on loans for the three months ended March 31, 2026 decreased $3.8 million. Changes in the provision are driven by changes in the estimate for the allowance for credit losses on loans.

At March 31, 2026, the allowance for credit losses increased $19.1 million compared to the allowance for credit losses on loans at December 31, 2025. The most significant driver of the increase in the allowance for credit losses is due to an increase in loan balances as a result of the acquisition of FineMark, as the initial allowance for FineMark loans acquired was $22.8 million. The allowance for credit losses on loans increased $8.4 million in the commercial portfolio, and the allowance for credit losses on the Company's personal banking portfolio increased $10.8 million. The allowance as a percentage of outstanding loans decreased compared to the prior quarter due to the change in mix of loans, as the acquired loan portfolio included more personal real estate loans which carry a lower allowance for credit losses than other classes. The forecast utilized to estimate the allowance for credit losses on loans at March 31, 2026 assumes a slow but continued economic expansion, and changes in the forecast utilized to estimate the allowance at March 31, 2026 did not significantly change the allowance estimate during the quarter. The allowance for credit losses on loans was $198.6 million at March 31, 2026 and was .97%, 1.01% and .96% of total loans at March 31, 2026, December 31, 2025 and March 31, 2025, respectively.

In the current quarter, the provision for credit losses on unfunded lending commitments was a benefit of $323 thousand, compared to a benefit of $608 thousand for the three months ended March 31, 2025. At March 31, 2026, the liability for unfunded lending commitments was $17.7 million, compared to $17.7 million at December 31, 2025 and $18.3 million at March 31, 2025. At March 31, 2026, the liability for unfunded lending commitments remained largely unchanged from December 31, 2025, because the initial liability recorded related to the FineMark acquisition of $362 thousand was largely offset by a decrease in the provision for the liability for unfunded lending commitments. 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 3 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 March 31, 2026.

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 the 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.

Non-accrual loans totaled $10.9 million at March 31, 2026, a decrease of $4.8 million from the balance at December 31, 2025. The decrease occurred mainly in business real estate non-accrual loans, which decreased $5.4 million. At March 31, 2026, non-accrual loans were comprised of business real estate (85.8%), personal real estate (12.1%), business (1.8%), and revolving home equity (0.3%) loans. Foreclosed real estate totaled $678 thousand at March 31, 2026, a decrease of $540 thousand compared to December 31, 2025. Total loans past due 90 days or more and still accruing interest totaled $22.8 million as of March 31, 2026, a decrease of $1.8 million from December 31, 2025. 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 3 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 $296.2 million at March 31, 2026 compared to $264.9 million at December 31, 2025, resulting in an increase of $31.3 million, or 11.8%.

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 March 31, 2026, the Company held $66.9 million of loans that had been modified during the three months ended March 31, 2026. These loans are further discussed in the "Modifications for borrowers experiencing financial difficulty" section in Note 3 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 3 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.

Revolving Home Equity Loans

The Company had $619.2 million in revolving home equity loans at March 31, 2026 that were collateralized by residential real estate. Most of these loans (94.9%) 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 March 31, 2026, the outstanding principal of loans with an original LTV higher than 80% was $78.6 million, or 12.6% of the portfolio, compared to $27.7 million as of December 31, 2025. Total revolving home equity loan balances over 30 days past due were $4.8 million at March 31, 2026 and $1.9 million at December 31, 2025, and the outstanding balance for revolving home equity loans on non-accrual status was $34 thousand at March 31, 2026 compared to no balance at December 31, 2025. The weighted average FICO score for the total portfolio balance at March 31, 2026 is 776. 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 2026 through 2029, approximately 20.5% of the Company's current outstanding balances are expected to mature. Of these balances, approximately 83.2% 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

The consumer loans category is mostly comprised of private banking loans and automobile loans. Private banking loans comprised of 48.2% of the consumer loan portfolio at March 31, 2026. The Company's private banking loans are mostly executive lines of credit, which are secured primarily by assets held by the Company's trust department, and insurance premium finance loans, which are primarily secured by life insurance policies. Automobile loans, which include direct and indirect product lines, comprised 30.5% of the consumer loan portfolio at March 31, 2026, and outstanding balances for auto loans were $754.3 million and $773.6 million at March 31, 2026 and December 31, 2025, respectively. The balances over 30 days past due amounted to $8.4 million at March 31, 2026 and $11.0 million at December 31, 2025, respectively, and comprised 1.1% of the outstanding balances of these loans at March 31, 2026 and 1.4% at December 31, 2025. For the three months ended March 31, 2026, $88.2 million of new auto loans were originated, compared to $98.0 million during the first three months of 2025. At

The Company's consumer loan portfolio also includes fixed rate home equity loans, typically for home repair or remodeling, and these loans comprised 8.5% of the consumer loan portfolio at March 31, 2026. Losses on these loans have historically been low, and the Company saw net recoveries of $591 thousand for the first three months of 2026. The remaining portion of the Company's consumer loan portfolio is comprised of healthcare financing, boat, RV, motorcycle, other equipment, and unsecured consumer loans. Net charge-offs on consumer loans, other than automobile and fixed rate home equity loans, totaled $755 thousand in the first three months of 2026 and were .2% of the average balances of these loans at March 31, 2026.

Consumer Credit Card Loans

The Company offers low promotional rates on selected consumer credit card products. Out of a portfolio at March 31, 2026 of $557.7 million in consumer credit card loans outstanding, approximately $120.5 million, or 21.6%, carried a low promotional rate. Within the next six months, $54.5 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.

Financial Condition

Balance Sheet

Total assets of the Company were $35.7 billion at March 31, 2026 and $32.9 billion at December 31, 2025. Earning assets (excluding the allowance for credit losses on loans and fair value adjustments on available for sale debt securities) amounted to $34.3 billion at March 31, 2026 and $31.4 billion at December 31, 2025, and consisted of 60% in loans and 28% in investment securities at March 31, 2026.

During the first quarter of 2026, average loans totaled $20.3 billion, an increase of $2.7 billion over the prior quarter, and an increase of $3.1 billion over the same quarter last year. The increase in average balances over both periods was primarily due to the acquisition of FineMark, which added $2.7 billion in loan balances. Compared to the previous quarter, average balances of personal real estate, business, business real estate, revolving home equity and consumer loans grew $1.4 billion, $369.3 million, $315.0 million, $238.9 million and $221.0 million, respectively. During the current quarter, the Company sold certain fixed rate personal real estate loans totaling $26.2 million, compared to $27.0 million in the prior quarter.

Total average available for sale debt securities decreased $269.0 million from the previous quarter to $8.9 billion, at fair value. The decrease in available for sale debt securities was mainly the result of lower average balances of mortgage-backed and asset-backed securities. During the first quarter of 2026, the unrealized loss on available for sale debt securities increased $40.7 million to $687.5 million, at period end. Also, during the first quarter of 2026, maturities and pay downs of available for sale debt securities were $410.7 million. At March 31, 2026, the duration of the available for sale investment portfolio was 4.2 years, and maturities and pay downs of approximately $1.2 billion are expected to occur during the next 12 months.

Average interest earning deposits with banks increased $210.4 million over average balances in the previous quarter, and the average balance within other assets increased $374.4 million mainly due to increases in goodwill, intangible assets, and premises and equipment related to the Company’s acquisition of FineMark.

Total average deposits increased $2.1 billion over the previous quarter. The increase in average balances was primarily due to the FineMark acquisition, which added $2.7 billion in interest bearing and $425 million in non-interest bearing deposit balances. Shortly after the acquisition, the Company moved $1.0 billion of FineMark’s high-cost, money market deposit balances off-balance sheet. Compared to the prior quarter, average interest checking and money market deposits and demand deposits increased $1.7 billion and $282.1 million, respectively. Additionally, average balances of certificates of deposit of $100,000 and over increased $76.0 million compared to the prior quarter, mainly due to deposit balances acquired from FineMark. Compared to the previous quarter, total average wealth and retail banking deposits grew $2.3 billion and $251.0 million, respectively, while commercial deposits declined $408.3 million. The average loans to deposits ratio was 73.4% in the current quarter and 69.0% in the prior quarter. The Company’s average borrowings, which included average customer repurchase agreements of $2.7 billion, increased $345.7 million to $2.9 billion in the first quarter of 2026.

The average loans to deposits ratio is a measure of a bank's liquidity, and the Company’s average loans to deposits ratio was 73.4% for the three months ended March 31, 2026. Core customer deposits, defined as non-interest bearing, interest checking, savings, and money market deposit accounts totaled $25.9 billion and represented 91.4% of the Company's total deposits at March 31, 2026. 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 increased $2.7 billion at March 31, 2026 compared to December 31, 2025, primarily due to an increase in wealth deposits from the acquisition of FineMark Holdings, Inc. While the Company considers core retail banking and wealth 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 $1.2 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 $6.9 billion through advances from the FHLB and the Federal Reserve.

Certificates of deposit of $100,000 or greater totaled $1.4 billion at March 31, 2026. These deposits are normally considered more volatile and higher costing, and comprised 5.0% of total deposits at March 31, 2026.

The Company may occasionally issue short-term brokered certificates of deposit to test the reliability of this potential funding source. 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 2026, the Company's outside borrowings have mainly been comprised of federal funds purchased and repurchase agreements, as follows:

Borrowings:
Federal funds purchased	$	129,730	$	132,370	$	128,625

Other debt	8,045		17,743		12,798
Total	$	2,584,768	$	2,417,779	$	3,002,439

Federal funds purchased, which totaled $129.7 million at March 31, 2026, are unsecured overnight borrowings obtained mainly from upstream correspondent banks with which the Company maintains approved lines of credit. At March 31, 2026, the Company had approved lines of credit totaling $4.4 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 March 31, 2026 were comprised of non-insured customer funds totaling $2.4 billion, and securities pledged as collateral for these retail agreements totaled $2.5 billion at March 31, 2026. 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 March 31, 2026.

The Company pledges certain assets, including loans and investment securities, to both the 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 March 31, 2026.

The Company receives outside ratings from both Standard & Poor’s and Moody’s on 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

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 increase in cash, cash equivalents and restricted cash of $295.6 million during the first three months of 2026, 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 $684.8 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 $859.2 million. This growth is primarily due to the cash assumed in the acquisition of FineMark Holdings, Inc., and sales, maturities, and pay downs (net of purchases) of investment securities, which provided cash of $428.9 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 $1.2 billion, largely resulting from repayments of FHLB borrowings (assumed in the FineMark acquisition), which used cash of $600.0 million, federal funds purchased and securities sold under agreements to repurchase, which used cash of $475.9 million, and a decrease of $287.7 million in deposits during the first three months of 2026. Cash dividend payments (including distributions to non-controlling interest) and purchases of treasury stock used cash of $41.9 million and $84.3 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 March 31, 2026 and December 31, 2025, as shown in the following table.


(Dollars in thousands)	March 31, 2026			December 31, 2025			Minimum Capital Requirement		Capital Conservation Buffer		Minimum Ratios Requirement including Capital Conservation Buffer		Minimum Ratios for Well-Capitalized Banks *

*Under Prompt Corrective Action requirements

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.

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. During the three months ended March 31, 2026, the Company purchased 1,624,840 shares at an average price of $51.56 in open market purchases and stock-based compensation transactions. At March 31, 2026, 1,634,000 shares remained available for purchase under the Board authorization in place at that date. On April 24, 2026, the share repurchase authorization was increased to 7,500,000 shares.

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 $.275 per share cash dividend on its common stock in the first quarter of 2026, which was a 5.0% increase compared to its 2025 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

Table of Contents

in the Company's 2025 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 March 31, 2026 totaled $16.9 billion (including $6.2 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 $668.8 million and $1.8 million, respectively, at March 31, 2026. 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 March 31, 2026, the liability for unfunded lending commitments totaled $17.7 million. See further discussion of the liability for unfunded lending commitments in Note 3 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 three months of 2026, purchases and sales of tax credits amounted to $14.0 million and $45.2 million, respectively. Fees from sales of tax credits were $1.5 million for the three months ended March 31, 2026, compared to $1.9 million in the same period last year. At March 31, 2026, the Company expected to fund outstanding purchase commitments of $142.9 million during the remainder of 2026 and had purchase commitments of $471.6 million that it expects to fund from 2027 through 2030.

The Company continued to maintain a strong liquidity position throughout the first three months of 2026. Through the various sources of liquidity described above, the Company maintains a liquidity position that it believes will adequately satisfy its financial obligations.

Retail Banking

For the three months ended March 31, 2026, income before income taxes for the Retail Banking segment decreased $5.7 million, or 10.4%, compared to the first three months of 2025. The decrease in income before income taxes was due to an increase in non-interest expense of $4.9 million, or 5.9%, and a decline in net interest income of $2.7 million, or 2.1%. These decreases to income were partly offset by a decline in the provision for credit losses of $979 thousand, or 9.6%, and an increase in non-interest income of $833 thousand, or 3.6%. Non-interest expense increased over the same period in the previous year mainly due to higher data processing and software costs and allocated support costs (mainly online banking, ATM and other non-branch support costs). Net interest income declined due to lower loan interest income of $2.0 million and lower net

Table of Contents

allocated funding credits assigned to the Retail Banking segment's loan and deposit portfolios of $1.0 million. The increase in non-interest income was mainly due to growth in deposit account fees (mainly overdraft and return items fees) and mortgage banking revenue. The decrease in the provision for credit losses from the first three months of 2025 was mainly due to lower auto loan net charge-offs.

Commercial

For the three months ended March 31, 2026, income before income taxes for the Commercial segment decreased $15.1 million, or 15.2%, compared to the same period in the previous year. This decrease was mainly due to higher non-interest expense, an increase in the provision for credit losses, and lower non-interest income, slightly offset by higher net interest income. Non-interest expense increased $8.9 million, or 8.5%, mainly due to higher legal fees, salaries and benefits expense and allocated service and support costs for commercial sales, credit administration and bank operations. The provision for credit losses increased $5.2 million, mainly due to a business real estate loan charge-off on a single senior living loan in the current year. Non-interest income decreased $1.4 million, or 2.0%, mainly due to a decrease in gains on the sales of assets, partly offset by higher deposit account fees (mainly corporate cash management fees). Net interest income increased $335 thousand, or .3%, mainly due to lower interest expense on deposits and customer repurchase agreements of $4.5 million and $3.9 million, respectively. These increases to income were largely offset by lower loan interest income of $6.7 million and lower allocated funding credits of $1.3 million.

Wealth

Wealth segment pre-tax profitability for the three months ended March 31, 2026 increased $18.2 million, or 40.5%, over the same period in the previous year. The increase was mainly due to the FineMark acquisition. Net interest income increased $24.0 million, or 108.1%, mainly due to a $38.3 million increase in loan interest income. This increase was partly offset by a $9.3 million increase in deposit interest expense and a $4.5 million decrease in net allocated funding credits. Non-interest income increased $16.2 million, or 25.3%, over the prior year largely due to higher private client and institutional trust fees. Non-interest expense increased $21.9 million, or 53.2%, mainly due to higher salaries and benefits, data processing and software, and occupancy expense. The provision for credit losses decreased $2 thousand from the same period last year.

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 $20.2 million higher than in the same period last year. Unallocated securities gains were $11.6 million in the first three months of 2026 compared to losses of $7.6 million in 2025. Also, the unallocated provision for credit losses decreased $7.7 million, primarily driven by a decrease in the provision for credit losses on loans, partly offset by an increase in 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 three months of 2026 was $11.3 million, or $3.7 million lower than net charge-offs. In the comparable period last year, the provision for credit losses on loans was $15.1 million, or $4.3 million higher than net charge-offs, due to an increase in the allowance for credit losses on loans. The allowance for credit losses on loans increased in the current year as a result of the FineMark initial allowance at acquisition of $22.8 million. For the three months ended March 31, 2026, the Company's provision on unfunded lending commitments was a benefit of $323 thousand. Additionally, net interest income and non-interest income increased $9.1 million and $1.3 million, respectively, but were offset by an increase in non-interest expense of $17.1 million.

Impact of Recently Issued Accounting Standards

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. The Company adopted this Update for the year ended December 31, 2025, and applied the new disclosures on a retrospective basis.

Purchased Loans The FASB issued ASU 2025-08 "Financial Instruments - Credit Losses (Topic 326): Purchased Loans" in November 2025. This new guidance makes significant changes to the accounting for certain acquired seasoned loans subject to the current expected credit loss model (CECL). Under the ASU, the initial allowance for credit losses recorded upon the acquisition of loans in scope is recognized as an adjustment to the amortized cost basis of the loan - similar to the model for purchased credit deteriorated assets. For these loans, the "day-one" credit loss estimate does not impact earnings immediately but is instead amortized over time as an adjustment to interest income. Subsequent changes in the allowance for credit losses are reported in earnings within credit loss expense. The ASU is effective for fiscal periods beginning after December 15, 2026 and interim periods within. Early adoption is permitted and amendments are to be applied prospectively. The Company adopted this Update on January 1, 2026.

Income Statement Reporting The FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" in November 2024. The amendments in this Update require new disclosures providing further detail of a company's income statement expense items. This Update is effective for annual periods beginning January 1, 2027, and interim periods beginning January 1, 2028. Early adoption is permitted. The amendments in this Update should be applied on a prospective basis. Other than the inclusion of additional disclosures, the adoption is not expected to have a significant effect on the Company's consolidated financial statements.

Internal-Use Software Development Costs The FASB issued ASU 2025-06, "Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvement to the Accounting for Internal-Use Software" in September 2025. The amendments in this Update are intended to modernize the accounting for internal-use software by eliminating references to software development project stages, making the guidance neutral to various development methodologies, including those currently in use and those that may be developed in the future. This Update is effective for annual and interim periods beginning after December 15, 2027. Early adoption is permitted as of the beginning of an annual reporting period. The amendments may be applied on a prospective, modified retrospective or full retrospective basis. The adoption is not expected to have a significant effect on the Company's consolidated financial statements.

Derivatives and Hedging The FASB issued ASU 2025-09 "Derivatives and Hedging (Topic 815): Hedge Accounting Improvements" in December 2025. The amendments in this Update make targeted improvements to hedge account intended to better align financial reporting with an entity's risk-management activities. At a high level, the Update provides for a broader application of grouping forecasted transactions in cash flow hedges by replacing 'same risk exposure' requirements with a more flexible 'similar risk exposure' standard, which may apply to the Company's current cash flow hedges. This Update is effective for annual and interim periods beginning after December 15, 2026. Early adoption is permitted in an interim or annual reporting period. The amendments should be applied on a prospective basis for all hedging relationships, and the Company may elect to adopt the amendments for existing hedging relationships as of the adoption, without dedesignating the hedges. The Company is currently evaluating the provisions of this Update.

Interim Reporting The FASB issued ASU 2025-11 "Interim Reporting (Topic 270): Narrow-Scope Improvements" in December 2025. The amendments in this Update are intended to clarify interim disclosure requirements and the applicability of Topic 270. The ASU is effective for interim periods within annual periods beginning after December 15, 2027. Early adoption is permitted and amendments may be applied prospectively or retrospectively to prior periods presented. The Company does not anticipate a significant impact 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 2025 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.


	March 31, 2026				December 31, 2025
(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	$	46.5	3.80	%		$	53.3	4.80	%
200 basis points rising	32.2		2.63			41.0		3.69
100 basis points rising	17.4		1.42			27.0		2.43
100 basis points falling	$	(20.1)	(1.64)	%		$	(23.6)	(2.13)	%
200 basis points falling	(30.0)		(2.45)			(39.4)		(3.54)
300 basis points falling	(38.6)		(3.16)			(53.7)		(4.84)

Under the simulation, in the three rising rate scenarios and three falling rate scenarios, interest rate risk is less asset sensitive when compared to the scenarios in the previous quarter. This change was primarily due to fluctuations in average interest earning cash balances at the Federal Reserve and an increase in rate sensitive deposits resulting from the FineMark acquisition, partly offset by an increase in loans acquired from FineMark.

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 March 31, 2026. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company's disclosure controls and procedures were effective.

As a result of its acquisition of FineMark, the Company has begun to integrate certain business processes and systems of FineMark. Accordingly, certain changes have been made and will continue to be made to our internal control over financial reporting until such time as this integration is complete. As permitted by guidance issued by the Office of the Chief Accountant of the SEC, companies may exclude controls of an acquired business from their assessment of internal control over financial reporting for a period not to extend more than one year beyond the date of the acquisition. Management’s assessment of the effectiveness of the Company’s internal control over financial reporting as of March 31, 2026 did not include the internal controls of FineMark, which the Company acquired on January 1, 2026. As of January 1, 2026, FineMark's assets represented approximately 12% of the Company's consolidated assets. There have been no other changes in the Company’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the three-month period ended March 31, 2026 that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.
