ZIONS BANCORPORATION, NATIONAL ASSOCIATION /UT/

September 30, 2025

1. BASIS OF PRESENTATION

Zions Bancorporation, National Association (“Zions Bancorporation, N.A.,” “the Bank,” “we,” “our,” “us”) is a bank headquartered in Salt Lake City, Utah. We provide a wide range of banking products and related services in 11 Western and Southwestern states through seven separately managed affiliates: Zions Bank in Utah, Idaho, and Wyoming; California Bank & Trust (“CB&T”); Amegy Bank (“Amegy”) in Texas; National Bank of Arizona (“NBAZ”); Nevada State Bank (“NSB”); Vectra Bank Colorado (“Vectra”) in Colorado and New Mexico; and The Commerce Bank of Washington (“TCBW”), which operates under that name in Washington and under The Commerce Bank of Oregon in Oregon.

The consolidated financial statements include our accounts and those of our majority-owned, consolidated subsidiaries. This also includes our wholly-owned subsidiaries, such as ZMFU II, Inc., which is utilized for our municipal lending business, and Zions Direct, Inc., a registered broker-dealer under the Exchange Act, among other subsidiaries.

Investments in which we have the ability to exercise significant influence over the operating and financial policies of the investee are accounted for using the equity method. All intercompany accounts and transactions have been eliminated in consolidation. Assets held in an agency or fiduciary capacity are excluded from the consolidated financial statements.

The accompanying unaudited consolidated financial statements of Zions Bancorporation, N.A., and its majority-owned subsidiaries have been prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all normal and recurring adjustments considered necessary for a fair presentation have been included. References to GAAP, including standards promulgated by the Financial Accounting Standards Board (“FASB”), are made according to sections of the Accounting Standards Codification.

The results of operations for the three and nine months ended September 30, 2025 and 2024 are not necessarily indicative of the results that may be expected in future periods. In preparing the consolidated financial statements, we are required to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying Notes. Actual results could differ from those estimates. For further information, refer to the consolidated financial statements and accompanying Notes included in our 2024 Form 10-K.

We evaluated events that occurred between September 30, 2025 and the date the consolidated financial statements were issued, and determined that there were no material events requiring adjustments to our consolidated financial statements or significant disclosure in the accompanying Notes.

2. RECENT ACCOUNTING PRONOUNCEMENTS

3. FAIR VALUE

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. For more information about our valuation methodologies for assets and liabilities measured at fair value, as well as the fair value hierarchy, see Note 3 of our 2024 Form 10-K.

Fair Value Hierarchy

The following schedule presents assets and liabilities measured at fair value on a recurring basis:

1 The Level 1 private equity investments (“PEIs”) generally relate to the portion of our Small Business Investment Company (“SBIC”) investments and other similar investments that are publicly traded.

Fair Value Option for Certain Loans Held for Sale

We have elected to apply the fair value option to certain commercial real estate (“CRE”) loans designated for sale to third-party conduits for securitization and hedged with derivative instruments. This election reduces accounting volatility that would otherwise arise from the mismatch between measuring loans held for sale at the lower of cost or fair value and derivatives at fair value, without requiring the application of hedge accounting. These loans are included in “Loans held for sale” on the consolidated balance sheet. Associated fair value gains and losses are included in “Capital markets fees and income” on the consolidated statement of income, while accrued interest is included in “Interest and fees on loans.”

At September 30, 2025 and December 31, 2024, we had $126 million and $25 million, respectively, of loans measured at fair value, with corresponding unpaid principal balance of $124 million and $26 million. During the first nine months of 2025 and 2024, we recognized approximately $6 million and $10 million, respectively, in net gains from loan sales and valuation adjustments related to loans measured at fair value and the associated derivatives.

Level 3 Valuations

Our Level 3 financial instruments include PEIs and agriculture loan servicing. For additional information regarding our Level 3 financial instruments, including the methods and significant assumptions used to estimate their fair value, see Note 3 of our 2024 Form 10-K.

Roll-forward of Level 3 Fair Value Measurements

The following schedule presents a roll-forward of assets and liabilities that are measured at fair value on a recurring basis using Level 3 inputs:

The roll-forward of Level 3 instruments includes the following realized gains and losses recognized in “Securities gains (losses), net” on the consolidated statement of income for the periods presented:

Nonrecurring Fair Value Measurements

Certain assets and liabilities may be measured at fair value on a nonrecurring basis. These include impaired loans measured at the fair value of the underlying collateral, other real estate owned (“OREO”), and equity investments without readily determinable fair values. Nonrecurring fair value adjustments generally arise from observable price changes for such equity investments, write-downs of individual assets, or the application of lower of cost or fair value accounting. At September 30, 2025, we had $22 million in collateral-dependent loans measured at fair value. During the third quarter of 2025, we recognized $6 million in losses related to fair value changes for these loans.

For additional information on assets and liabilities measured at fair value on a nonrecurring basis, see Note 3 of our 2024 Form 10-K.

Fair Value of Certain Financial Instruments

The following schedule presents the carrying values and estimated fair values of certain financial instruments:

The preceding schedule excludes certain financial instruments that are recorded at fair value on a recurring basis, as well as certain financial assets and liabilities for which the carrying value approximates fair value. For additional information regarding the financial instruments included within the scope of this disclosure, along with the valuation methodologies and significant assumptions used in estimating their fair values, see Note 3 of our 2024 Form 10-K.

4. OFFSETTING ASSETS AND LIABILITIES

The following schedule presents gross and net information for selected financial instruments on the balance sheet:

Security repurchase and reverse repurchase agreements are offset on the consolidated balance sheet according to master netting agreements, when applicable. Security repurchase agreements are included in “Federal funds and other short-term borrowings” on the consolidated balance sheet. Derivative instruments may also be offset under their master netting agreements; however, for accounting purposes, they are presented on a gross basis on the consolidated balance sheet. For more information regarding derivative instruments, see Note 7.

5. INVESTMENT SECURITIES

Investment Securities

We classify our investment securities as either available-for-sale (“AFS”) or held-to-maturity (“HTM”). AFS securities, which primarily consist of debt securities used to manage liquidity and interest rate risk and to generate interest income, are measured at fair value. Unrealized gains and losses from AFS securities, net of applicable taxes, are recorded in other comprehensive income. HTM securities are those that management has both the intent and ability to hold until maturity and are carried at amortized cost. This amount reflects the original investment cost, adjusted for the amortization or accretion of any purchase premiums or discounts, as well as any impairment losses, including credit-related impairment. Gains or losses on the sale of investment securities are recognized in noninterest income using the specific identification method.

The carrying values of our investment securities exclude accrued interest receivables of$57 million and $60 million at September 30, 2025 and December 31, 2024, respectively. These receivables are included in “Other assets” on the consolidated balance sheet.

Investment securities with a carrying value of $17.4 billion and $17.9 billion were pledged as collateral for potential borrowings at September 30, 2025 and December 31, 2024, respectively.

When a security is transferred from AFS to HTM, the difference between its amortized cost basis and fair value at the date of transfer is amortized as a yield adjustment through interest income. The fair value at the date of transfer results in either a premium or discount to the amortized cost basis of the HTM securities. The amortization of unrealized gains or losses reported in accumulated other comprehensive income (“AOCI”) will offset the effect of the amortization of the premium or discount in interest income created by the transfer. The discount associated with securities previously transferred from AFS to HTM was $1.7 billion ($1.2 billion after tax) at September 30, 2025, compared with $1.8 billion ($1.4 billion after tax) at December 31, 2024.

For additional information regarding our fair value estimation process and the accounting treatment of our investment securities, see Notes 3 and 5, respectively, of our 2024 Form 10-K.

The following schedule presents the amortized cost and estimated fair values of our AFS and HTM securities:

1 Gross unrealized gains for the respective AFS security categories without values were individually less than $1 million.

The following schedule presents gross unrealized losses for AFS securities and the estimated fair value, categorized by the length of time the securities have been in an unrealized loss position:

At September 30, 2025 and December 31, 2024, the number of AFS investment securities in an unrealized loss position was 2,135 and 2,534, respectively.

There wereno gross realized gains or losses from sales of AFS investment securities for the three and nine months ended September 30, 2025 and 2024.

The following schedule presents interest income categorized by investment security type:

Maturities

The following schedule presents the amortized cost and weighted average yields of debt securities, categorized by the remaining contractual maturity of principal payments at September 30, 2025. The schedule does not reflect the impact of interest rate resets or fair value hedges. Additionally, the remaining contractual principal maturities presented do not represent the portfolio's duration, as they do not incorporate expected prepayments or amortization, which generally result in measured durations that are shorter than contractual maturities.

1 The yields on tax-exempt securities are calculated on a tax-equivalent basis.

Impairment

On a quarterly basis, we review our investment securities portfolio to assess potential impairment on an individual security level. For additional information regarding our impairment assessment methodology and related accounting policies applicable to investment securities, see Note 5 of our 2024 Form 10-K.

AFS Impairment

No impairment losses were recognized on our AFS investment securities portfolio during the first nine months of either 2025 or 2024. The unrealized losses primarily reflect the impact of higher interest rates following the purchase of the securities and are not attributable to credit-related factors. Accordingly, absent any future sales, we expect to recover the full principal value of these securities upon maturity. At September 30, 2025, we did not intend to sell any securities in an unrealized loss position, nor do we believe it is more likely than not that we would be required to sell such securities prior to recovering their amortized cost basis.

HTM Impairment

For HTM securities, the allowance for credit losses (“ACL”) is evaluated using the same methodology applied to loans and leases measured at amortized cost, as described in Note 6. At September 30, 2025, the ACL for HTM securities wasless than $1 million. All HTM securities were assigned a credit quality rating of“Pass,” with none classified as past due.

6. LOANS, LEASES, AND ALLOWANCE FOR CREDIT LOSSES

Loans, Leases, and Loans Held for Sale

The following schedule presents our loan and lease portfolio according to major portfolio segment and specific class:

Loans and leases classified as held for investment are measured and presented at their amortized cost basis, which includes net unamortized purchase premiums, discounts, and deferred loan fees and costs totaling $56 million and $43 million at September 30, 2025 and December 31, 2024, respectively. The amortized cost basis of the loans does not include accrued interest receivables of $278 million and $281 million at September 30, 2025 and December 31, 2024, respectively. These receivables are included in “Other assets” on the consolidated balance sheet.

Municipal loans typically consist of obligations that are repaid from, or secured by, the general funds or pledged revenues of municipalities, as well as by real estate or equipment. This portfolio also includes loans extended to private commercial and 501(c)(3) not-for-profit organizations that utilize a pass-through municipal structure to benefit from favorable tax treatment.

Land acquisition and development loans included in the construction and land development loan portfolio were $234 million at September 30, 2025 and $260 million at December 31, 2024.

Loans with a carrying value of $42.6 billion at September 30, 2025 and $40.4 billion at December 31, 2024 have been pledged at the Federal Reserve (“FRB”) and the Federal Home Loan Bank (“FHLB”) of Des Moines as collateral for current and potential borrowings.

Loans held for sale are measured individually at fair value or the lower of cost or fair value and primarily consist of CRE loans sold into securitization entities, and conforming residential mortgages generally sold to U.S. government agencies. The following schedule presents loans added to, or sold from, the held for sale category during the periods presented:

Occasionally, we have continuing involvement in sold loans through retained servicing rights or guarantees. At September 30, 2025 and December 31, 2024, the principal balance of sold loans for which we retained servicing rights was approximately $702 million and $615 million, respectively. Income generated from sold loans, excluding servicing, totaled $4 million and $9 million for the three and nine months ended September 30, 2025, respectively, and $2 million and $5 million for the corresponding periods in 2024.

Allowance for Credit Losses

The allowance for credit losses (“ACL”), which consists of the allowance for loan and lease losses (“ALLL”) and the reserve for unfunded lending commitments (“RULC”), represents our estimate of current expected credit losses related to the loan and lease portfolio and unfunded lending commitments as of the balance sheet date. For additional information regarding our policies and methodologies used to estimate the ACL, see Note 6 of our 2024 Form 10-K.

The ACL on AFS and HTM debt securities is estimated independently from the ACL on loans. For HTM securities, the ACL is evaluated using the same methodology applied to loans and leases measured at amortized cost. For more information regarding our methodology used to estimate the ACL on AFS and HTM debt securities, see Note 5 of our 2024 Form 10-K.

Changes in the ACL are summarized as follows:

Nonaccrual Loans

Loans are generally placed on nonaccrual status when the full collection of principal and interest is not expected, or when the loan is 90 days or more past due with respect to principal or interest, unless it is both well-secured and in the process of collection. We consider several factors when placing a loan on nonaccrual status, including delinquency status, collateral valuation, borrower or guarantor financial condition, bankruptcy status, and other indicators that suggest uncertainty regarding the full and timely recovery of principal and interest.

A nonaccrual loan may be returned to accrual status when the following conditions are met: (1) all delinquent principal and interest have been brought current in accordance with the loan agreement; (2) the loan, if secured, is well secured; (3) the borrower has made timely payments under the contractual terms for a minimum of six months; and (4) a credit analysis indicates reasonable assurance of the borrower's ability and willingness to continue making payments.

The following schedule presents the amortized cost basis of loans on nonaccrual:

For accruing loans, interest is accrued, and interest payments are recognized as interest income in accordance with the contractual terms of the loan agreement. For nonaccruing loans, the accrual of interest is discontinued, and any previously accrued but uncollected interest is promptly reversed from interest income, generally within one month. Payments received on nonaccrual loans are not recognized as interest income, but are applied to reduce the outstanding principal balance. However, when the collectability of the amortized cost basis of a nonaccrual loan is no longer in doubt, interest payments may be recognized as interest income on a cash basis. For the three and nine months ended September 30, 2025 and 2024, no interest income was recognized on a cash basis for nonaccrual loans.

The following schedule presents the amount of accrued interest receivables reversed from interest income, categorized by loan portfolio segment during the periods presented:

Past Due Loans

Closed-end loans with payments scheduled monthly are reported as past due when the borrower is in arrears for two or more monthly payments. Similarly, open-end credits, such as bankcard and other revolving credit plans, are reported as past due when the minimum payment has not been made for two or more billing cycles. Other multi-payment obligations (i.e., quarterly, semi-annual, etc.), single payment, and demand notes, are reported as past due when either principal or interest is due and unpaid for a period of 30 days or more.

Past due loans (accruing and nonaccruing) are summarized as follows:

1 Represents nonaccrual loans that are not past due more than 30 days; however, full payment of principal and interest is not expected.

Credit Quality Indicators

In addition to the nonaccrual and past due criteria, we also analyze loans using loan risk-grading systems, which vary based on the size and type of credit risk exposure. The internal risk grades assigned to loans follow our definition of Pass, Special Mention, Substandard, and Doubtful, which align with published regulatory risk classifications.

Definitions of Pass, Special Mention, Substandard, and Doubtful are summarized as follows:

•Pass — A Pass asset is higher-quality and does not fit any of the other categories described below. The likelihood of loss is considered low.

•Special Mention — A Special Mention asset has potential weaknesses that warrant management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or our credit position at some future date.

•Substandard — A Substandard asset is inadequately protected by the current sound worth and paying capacity of the obligor or the collateral pledged, if any. Assets classified as Substandard have well-defined weaknesses and are characterized by the distinct possibility that we may sustain some loss if deficiencies are not corrected.

•Doubtful — A Doubtful asset has all the weaknesses inherent in a Substandard asset, with the added characteristics that the weaknesses make collection or liquidation in full highly questionable and improbable.

The amount of loans classified as Doubtful totaled $10 million at September 30, 2025, compared with $14 million at December 31, 2024, and are included in the nonaccrual balances in the schedule below.

For commercial and CRE loans with commitments greater than $1 million, we assign one of multiple grades within the Pass classification or one of the previously described risk classifications. We assess our internal risk grades quarterly, or as soon as we identify information that affects the credit risk of the loan.

For consumer loans and for commercial and CRE loans with commitments of $1 million or less, we generally assign internal risk grades similar to those previously described based on automated rules that consider refreshed credit scores, payment performance, and other risk indicators. These loans are generally assigned either a Pass, Special Mention, or Substandard grade, and are reviewed as we identify information that might warrant a grade change.

The following schedule presents the amortized cost basis of loans and leases categorized by year of origination and by credit quality classification as monitored by management. Loans that have been modified resulting in substantially different terms than the original loan are included in the period in which the modification occurred.

The following schedules present gross charge-offs by year of loan origination for the periods presented.

Loan Modifications

Loans may be modified in the normal course of business for competitive reasons or to strengthen our collateral position. Loan modifications may also occur when the borrower experiences financial difficulty and needs temporary or permanent relief from the original contractual terms of the loan. For loans that have been modified with a borrower experiencing financial difficulty, we use the same credit loss estimation methods that we use for the rest of the loan portfolio. These methods incorporate the post-modification loan terms, as well as defaults and charge-offs associated with historical modified loans. All nonaccruing loans more than $1 million are evaluated individually, regardless of modification.

We consider many factors in determining whether to agree to a loan modification and we seek a solution that will both minimize potential loss to us and attempt to help the borrower. We evaluate borrowers’ current and forecasted future cash flows, their ability and willingness to make current contractual or proposed modified payments, the value of the underlying collateral (if applicable), the possibility of obtaining additional security or guarantees, and the potential costs related to a repossession or foreclosure and the subsequent sale of the collateral.

A modified loan on nonaccrual will generally remain on nonaccrual until the borrower has proven the ability to perform under the modified structure for a minimum of six months, and there is evidence that such payments can and are likely to continue as agreed. Performance prior to the modification, or significant events that coincide with the modification, are included in assessing whether the borrower can meet the new terms and may result in the loan being returned to accrual at the time of modification or after a shorter performance period. If the borrower’s ability to meet the revised payment schedule is uncertain, the loan remains on nonaccrual.

On an ongoing basis, we monitor the performance of all modified loans in accordance with their modified terms. For the three and nine months ended September 30, 2025, the amortized cost of modified loans that experienced a payment default within 12 months of modification and remained in default at period end was approximately $2 million and $4 million, respectively. For the three and nine months ended September 30, 2024, the corresponding amounts were $5 million for both periods.

The amortized cost of loans to borrowers experiencing financial difficulty that were modified during the period, by loan class and modification type, is summarized in the following schedule:

1 Includes modifications that resulted from a combination of interest rate reduction, maturity or term extension, principal forgiveness, and payment deferral modifications.

2 Unfunded lending commitments related to loans modified to borrowers experiencing financial difficulty totaled$29 million and $8 million at September 30, 2025 and September 30, 2024, respectively.

3 Amounts less than 0.05% are rounded to zero.

The financial impact of loan modifications to borrowers experiencing financial difficulty is summarized in the following schedules:

1 Primarily relates to a small number of loans within each consumer loan class.

For the three and nine months ended September 30, 2025, loan modifications granted to borrowers experiencing financial difficulty resulted in approximately $2 million in principal forgiveness across the total loan portfolio, compared with less than $1 million during the corresponding periods in 2024.

The following schedule presents the aging of loans to borrowers experiencing financial difficulty that were modified on or after October 1, 2024 through September 30, 2025, presented by portfolio segment and loan class:

The following schedule presents the aging of loans to borrowers experiencing financial difficulty that were modified on or after October 1, 2023 through September 30, 2024, presented by portfolio segment and loan class:

Collateral-Dependent Loans

When a loan is individually evaluated for expected credit losses, we estimate a specific reserve for the loan based on (1) the projected present value of the loan’s future cash flows discounted at the loan’s effective interest rate, (2) the observable market price of the loan, or (3) the fair value of the loan’s underlying collateral.

Select information on loans for which the borrower is experiencing financial difficulties and repayment is expected to be provided substantially through the operation or sale of the underlying collateral, including the type of collateral and the extent to which the collateral secures the loans, is summarized as follows:

1 The fair value is based on the most recent appraisal or other collateral evaluation.

Foreclosed Residential Real Estate

The balance of foreclosed residential real estate property was $1 million at September 30, 2025, compared with less than $1 million at December 31, 2024. The amortized cost basis of consumer mortgage loans collateralized by residential real estate property that were in the process of foreclosure was $21 million and $14 million for the same periods, respectively.

7. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Objectives and Accounting

Our primary objective in utilizing derivative instruments is to manage interest rate risk. Derivatives serve as a strategic tool to mitigate volatility in interest income, interest expense, earnings, and capital by adjusting our sensitivity to various market risks. Specifically, we employ derivatives to stabilize forecasted interest income from variable-rate assets and to modify the coupon or duration of fixed-rate financial assets or liabilities when appropriate. Additionally, we offer derivative solutions to assist customers in managing their own risk exposures.

We designate certain derivatives under U.S. GAAP as hedging instruments for specific risks and are subject to documentation and effectiveness testing requirements. However, not all derivatives used in our risk management activities qualify for hedge accounting. Those not designated as accounting hedges are primarily utilized to economically manage exposure to certain market risks, including interest rate and foreign exchange movements. These instruments are not used for speculative purposes and either do not require hedge accounting to reflect their economic impact appropriately in our financial statements or do not meet the criteria for hedge accounting. For more information about our use of and accounting policies for derivative instruments, see Note 7 of our 2024 Form 10-K.

Collateral and Credit Risk

Credit risk associated with derivatives arises from the potential for counterparty nonperformance. To date, we have not experienced significant losses due to counterparty default. For more information on how counterparty credit risk is incorporated into derivative valuations, see Note 3 of our 2024 Form 10-K. For additional discussion on collateral and related credit risk for derivative contracts, see Note 7 of our 2024 Form 10-K.

Certain derivative contracts may require us to pledge collateral for derivatives in a net liability position at a given balance sheet date. These contracts include credit risk-related contingent features, such as maintaining a minimum debt credit rating. If such a feature is triggered, e.g., a downgrade of our credit rating, we may be required to pledge additional collateral. Historically, counterparties have not always exercised their contractual right to demand additional collateral.

At September 30, 2025, the fair value of our derivative liabilities was $257 million. To satisfy variation margin requirements, we pledged $24 million in cash collateral in the ordinary course of business. Additionally, we pledged $200 million in U.S. Treasuries to meet initial margin requirements with certain dealer counterparties and central clearing houses. A one-notch downgrade in our credit rating by either Standard & Poor’s (“S&P”) or Moody’s at September 30, 2025 would likely not result in a requirement to pledge additional collateral. Centrally cleared derivatives do not contain credit risk-related features that would require additional collateral in the event of a credit rating downgrade.

We assess counterparty credit risk through the calculation of a credit valuation adjustment (“CVA”), which reflects the value of nonperformance risk for both our counterparties and the Bank. The fair value of derivatives includes a net CVA, which reduced the fair value of derivative assets by $3 million at September 30, 2025, and reduced the fair value of derivative liabilities by $9 million at December 31, 2024. The net CVA is included in “Capital markets fees and income” on the consolidated statement of income.

Derivative Amounts

The following schedule presents derivative notional amounts and recorded gross fair values at September 30, 2025 and December 31, 2024:

1 Includes forward-starting swaps that are not yet effective.

2 We provide certain borrowers with access to over-the-counter derivatives. To manage the associated exposures, we typically enter into offsetting derivative transactions with dealers or central clearing houses, which include terms that closely mirror those of the original borrower transactions. Notional amounts for derivatives that are not designated as accounting hedges include both customer-facing derivatives and offsetting dealer-facing derivatives.

3 Includes both spot and forward FX trades.

The following schedules present the gains and losses from derivative instruments designated as cash flow and fair value hedges, either deferred in AOCI or recognized in earnings for the three and nine months ended September 30, 2025 and 2024:

1 For the 12-month period following September 30, 2025, we estimate that approximately $37 million in net losses from both active and terminated cash flow hedges will be reclassified from AOCI into interest income. At September 30, 2025, approximately $48 million in losses related to terminated cash flow hedges remained deferred in AOCI. These deferred losses are expected to be fully reclassified into earnings by October 2027.

2 At September 30, 2025 and 2024, we recorded cumulative unamortized basis adjustments from terminated fair value hedges of debt totaling $34 million and $41 million, respectively. Additionally, we maintained $3 million in cumulative unamortized basis adjustments from terminated fair value hedges of assets at both reporting dates. The interest amounts associated with fair value hedges, as presented above, include the amortization of these remaining unamortized basis adjustments.

The following schedule presents the amount of gains (losses) recognized from derivatives not designated as

accounting hedges:

The following schedule presents derivatives used in fair value hedge accounting relationships, including the pre-tax gains and losses recognized on both the derivatives and the corresponding hedged items for the periods presented:

1 Includes hedges of benchmark interest rate risk for fixed-rate long-term debt, AFS securities, and commercial loans. Gains and losses were recorded in interest income or expense, consistent with the hedged items.

2 The income/expense for derivatives does not reflect interest income/expense from periodic accruals and payments to be consistent with the presentation of the gains (losses) on the hedged items.

The following schedule presents information regarding basis adjustments for hedged items in fair value hedging relationships:

1 Carrying amounts exclude (1) issuance and purchase discounts or premiums, (2) unamortized issuance and acquisition costs, and (3) amounts related to terminated fair value hedges.

2 At September 30, 2025, the amortized cost basis of assets designated using the portfolio layer method was $9.5 billion; the cumulative basis adjustment associated with these hedging relationships was $35 million; and the notional amounts of the designated accounting hedges were $5.6 billion.

8. LEASES

We have operating and finance leases for branches, data centers, and corporate offices, including our headquarters in Salt Lake City, Utah. At September 30, 2025, we had 408 branches, with 278 owned and 130 leased. The remaining maturities of our lease commitments range from the year 2025 to 2062, with some lease arrangements including options to extend or terminate the leases.

Leases with terms longer than twelve months are reported as a lease liability with a corresponding right-of-use (“ROU”) asset. ROU assets for operating leases and finance leases are included in “Other assets” and “Premises, equipment and software, net” on the consolidated balance sheet, respectively. The corresponding liabilities for those leases are included in “Other liabilities” and “Long-term debt,” respectively. For more information about our lease policies, see Note 8 of our 2024 Form 10-K.

The following schedule presents ROU assets and lease liabilities with the associated weighted average remaining life and discount rate:

The following schedule presents additional information related to lease expense:

1 Other expenses primarily include property taxes and building and property maintenance.

The following schedule presents the total contractual undiscounted lease payments for operating lease liabilities by expected due date for each of the next five years:

1 Represents contractual maturities remaining in 2025.

We enter into certain lease agreements as the lessor of real estate, including bank-owned and subleased properties, to generate cash flow. This activity includes leasing vacant suites within buildings that we partially occupy. Operating lease income totaled$4 million and$3 million for the third quarter of 2025 and 2024, respectively, and $11 million and $10 million for the first nine months of 2025 and 2024, respectively.

At September 30, 2025 and December 31, 2024, we originated equipment leases classified as sales-type or direct-financing leases totaling $349 million and $377 million, respectively. Income from these leases was$5 million for both the third quarters of 2025 and 2024, and $14 million for both the first nine months of 2025 and 2024.

9. LONG-TERM DEBT AND SHAREHOLDERS’ EQUITY

Long-Term Debt

The long-term debt carrying values presented on the consolidated balance sheet represent the par value of the debt, adjusted for any unamortized premium or discount, unamortized debt issuance costs, and fair value hedge basis adjustments. During the third quarter of 2025, we issued $500 million in 4.70% Fixed-to-Floating Senior Notes with a maturity date of August 18, 2028.

The following schedule presents the components of our long-term debt:

LONG-TERM DEBT

1 The change in the subordinated note balance is primarily due to fair value hedge basis adjustments. See also Note 7.

Shareholders' Equity

Our common stock is traded on the National Association of Securities Dealers Automated Quotations (“NASDAQ”) Global Select Market. At September 30, 2025, there were 147.6 million shares of$0.001 par value common stock outstanding. Common stock and additional paid-in capital was$1.7 billion at both September 30, 2025 and December 31, 2024.

At September 30, 2025, the AOCI balance reflected a net loss of$2.1 billion, primarily attributable to a decline in the fair value of fixed-rate AFS securities as a result of changes in interest rates. This amount includes $1.7 billion ($1.2 billion after tax) of unrealized losses associated with securities previously transferred from AFS to HTM. The following schedule presents the changes in AOCI by major component:

10. COMMITMENTS, GUARANTEES, AND CONTINGENT LIABILITIES

Commitments and Guarantees

We utilize various financial instruments, including loan commitments, commercial letters of credit, and standby letters of credit, to support our customers’ financing needs. These instruments expose us to varying degrees of credit, liquidity, and interest rate risk that are not fully reflected on the consolidated balance sheet. The associated credit risk is evaluated and recorded as a reserve for unfunded lending commitments, which is presented separately on the consolidated balance sheet.

The following schedule presents the contractual amounts related to off-balance sheet financial instruments used to support our customers’ financing needs:

1 Net of participations.

For more information about these commitments and guarantees including their terms and collateral requirements, see Note 16 of our 2024 Form 10-K.

Legal Matters

We are involved in various legal proceedings or governmental inquiries, which may include litigation in court, arbitral proceedings, investigations, examinations, and other actions initiated or considered by governmental and self-regulatory agencies. Litigation may pertain to lending, deposit and other customer relationships, supplier and contractual issues, employee matters, intellectual property matters, personal injuries and torts, regulatory and legal compliance, and other matters. While most matters involve individual claims, we are also subject to putative class action claims and similar broader claims. Proceedings, investigations, examinations, and other actions initiated or considered by governmental and self-regulatory agencies may relate to our banking, investment advisory, trust, securities, and other products and services; and our customers’ involvement in money laundering, fraud, securities violations and other illicit activities or our policies and practices concerning such customer activities. Additionally, these actions may pertain to our compliance with the broad range of banking, securities and other applicable laws and regulations. At any given time, we may be responding to subpoenas, requests for documents, data, and testimony relating to these matters and engaging in discussions to resolve them.

At September 30, 2025, we were subject to the following material litigation:

•Two civil cases, Lifescan, Inc. and Johnson & Johnson Health Care Services v. Jeffrey C. Smith, et. al., brought against us in the United States District Court for the District of New Jersey in December 2017, and Roche Diagnostics and Roche Diabetes Care Inc. v. Jeffrey C. Smith, et. al., brought against us in the United States District Court for the District of New Jersey in March 2019. In these cases, certain manufacturers and distributors of medical products seek to hold us liable for allegedly fraudulent practices of a borrower of the Bank who filed for bankruptcy protection in 2017. Discovery is substantially complete for most parties. However, final rulings on certain dispositive motions remain outstanding, and other dispositive motions have yet to be filed or ruled upon. A court-ordered mediation is expected to occur in late 2025. Both cases have been set for trial in April 2027.

•Cayon and Reesor v. Zions Bancorporation, N.A. is an arbitration matter pending before Judicial Arbitration and Mediation Services. The claimants have asserted claims for unpaid overtime, meal and rest break violations, and failure to reimburse work-related expenses. They have also initiated a related action under the California Private Attorneys General Act (“PAGA”). The parties have reached a preliminary agreement to resolve the individual and collective claims raised in the arbitration and the related PAGA action. The settlement remains subject to final documentation and court approval.

Based on our current knowledge, we believe that our estimated liability for litigation and other legal actions and claims, as reflected in our accruals and determined in accordance with applicable accounting guidance, is adequate. We also believe that any liabilities in excess of the amounts currently accrued, if any, arising from litigation and other legal actions and claims for which an estimate is possible, will not have a material impact on our financial condition, results of operations, or cash flows. However, given the significant uncertainties involved in these matters, and the potentially large or indeterminate damages sought in some cases, an adverse outcome in one or more of these matters could materially affect our financial condition, results of operations, or cash flows for any given reporting period.

Any estimate or determination regarding the future resolution of litigation, arbitration, governmental or self-regulatory examinations, investigations or similar matters is inherently uncertain and involves significant judgment. This is particularly true in the early stages of a legal matter, when legal issues and facts have not been fully articulated, reviewed, analyzed, and vetted through discovery, trial or hearing preparation, substantive and productive mediation or settlement discussions, or other actions. It is also especially true for class actions and similar claims involving multiple defendants, matters with complex procedural requirements or substantive issues, novel legal theories, and examinations, investigations, and other actions conducted or brought by governmental and self-regulatory agencies, where the normal adjudicative process is not applicable. As a result, we are often unable to determine whether a favorable or unfavorable outcome is remote, reasonably likely, or probable, or to estimate the amount or range of a probable or reasonably likely loss, until relatively late in the course of a legal matter, sometimes not until a number of years have elapsed. Consequently, our judgments and estimates relating to claims will change over time in light of developments, and actual outcomes will differ from our estimates. These differences may be material.

11. REVENUE FROM CONTRACTS WITH CUSTOMERS

Noninterest income and revenue from contracts with customers are recognized when control of the promised goods or services is transferred to customers, in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. We recognize noninterest income from certain contracts with customers upon satisfaction of the related contractual performance obligations. For more information regarding revenue from contracts with customers, see Note 17 of our 2024 Form 10-K.

Disaggregation of Revenue

The following schedule presents revenue from contracts with customers and provides a reconciliation to total noninterest income by operating business segment for the three months ended September 30, 2025 and 2024. Customer-related noninterest income from other sources represents revenue earned from customers that is not within the scope of the applicable accounting guidance for revenue from contracts with customers.

1 Card fees exclude costs associated with reward programs that are netted against interchange fees, as these costs fall outside the scope of the applicable accounting guidance for revenue from contracts with customers.

2 Capital markets fees and income excludes revenue related to real estate capital markets, swaps, loan syndications, foreign exchange activities, and the net CVA, as these items are not within the scope of the applicable accounting guidance for revenue from contracts with customers.

The following schedule presents revenue from contracts with customers and provides a reconciliation to total noninterest income by operating business segment for the nine months ended September 30, 2025 and 2024. Customer-related noninterest income from other sources represents revenue from customers that falls outside the scope of the applicable accounting guidance for revenue from contracts with customers.

1 Card fees exclude costs associated with reward programs that are netted against interchange fees, as these costs are not within the scope of applicable accounting guidance for revenue from contracts with customers.

2 Capital markets fees and income excludes revenue related to real estate capital markets, swaps, loan syndications, foreign exchange activities, and the net CVA, as these items are not within the scope of the applicable accounting guidance for revenue from contracts with customers.

Revenue from contracts with customers did not result in the recognition of significant contract assets and liabilities. Contract receivables are included in “Other assets” on the consolidated balance sheet. Payment terms vary by the nature of the services provided; however, the time between the satisfaction of performance obligations and receipt of payment is generally not significant.

12. INCOME TAXES

The effective income tax rate was 22.1% for the third quarter of 2025, compared with 22.7% for the third quarter of 2024. For the nine months ended September 30, the effective tax rates were 23.9% in 2025 and 23.5% in 2024. The tax rates during these periods were increased by the nondeductibility of certain Federal Deposit Insurance Corporation (“FDIC”) premiums, specific executive compensation, and other fringe benefits. While the FDIC insurance premiums are not deductible for tax purposes, FDIC special assessments are tax deductible. Conversely, the tax rates were reduced by nontaxable municipal interest income and nontaxable income from certain bank-owned life insurance policies.

The tax rates for the nine months ended September 30, 2025 were further impacted by the enactment of new state tax legislation across multiple jurisdictions during the first and second quarters of 2025. These legislative changes required a revaluation of our net deferred tax asset (“DTA”), which primarily arises from unrealized losses in AOCI on certain securities.

At September 30, 2025 and December 31, 2024, our net DTA totaled $756 million and $904 million, respectively. The net DTA or deferred tax liability (“DTL”) is included in either “Other assets” or “Other liabilities,” respectively, on the consolidated balance sheet.

We regularly evaluate DTAs to determine whether a valuation allowance is required, applying a “more-likely-than-not” threshold for realization. Based on this evaluation, management concluded that no valuation allowance was required at both September 30, 2025 and December 31, 2024.

13. NET EARNINGS PER COMMON SHARE

14. OPERATING SEGMENT INFORMATION

We manage our operations with a focus on geographic area, primarily in the states of Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Texas, Utah, Washington, and Wyoming. We conduct our operations primarily through seven separately managed affiliate banks, each with its own local branding and management team: Zions Bank, California Bank & Trust, Amegy Bank, National Bank of Arizona, Nevada State Bank, Vectra Bank Colorado, and The Commerce Bank of Washington. These affiliate banks comprise our primary operating segments. We emphasize local authority, responsibility, pricing, and customization of certain products to maximize customer satisfaction, strengthen community relations, and improve profitability and shareholder returns.

At September 30, 2025, Zions Bank operated 93 branches in Utah,25 branches in Idaho, andone branch in Wyoming. CB&T operated 77 branches in California, including thefour FirstBank Coachella Valley, California branches we acquired in late March 2025. Amegy operated 76 branches in Texas. NBAZ operated 56 branches in Arizona. NSB operated 43 branches in Nevada. Vectra operated 33 branches in Colorado andone branch in New Mexico. TCBW operatedtwo branches in Washington andone branch in Oregon. During the first nine months of 2025, all of the Bank's assets and revenues were located in or derived from operations within the United States.

We focus on serving customers in the communities where we operate. Each of our operating segments offers a wide range of banking products and related services, delivered digitally or through other channels. These include primarily commercial and small business banking, capital markets and investment banking, commercial real estate lending, retail banking, and wealth management.

Our affiliate banks are supported by an enterprise operating segment, referred to as the “Other” segment, which provides governance and risk management, allocates capital, establishes strategic objectives, and includes centralized technology, back-office functions, and certain lines of business not operated through our affiliate banks. The costs of centrally provided services are allocated to the operating segments based on estimated or actual usage of those services. Capital is allocated according to the risk-weighted assets held by each segment. We use an internal funds transfer pricing (“FTP”) allocation process to report the results of operations for each segment. This process is subject to ongoing changes and refinements. The total average loans and deposits for the operating segments include minor intercompany amounts and may also include deposits with the “Other” segment. Transactions between segments are primarily conducted at fair value, with profits eliminated for consolidated reporting purposes.

We evaluate performance and allocate resources primarily based on income or loss from operations before income taxes. The accounting policies of the operating segments align with those in the Notes to Consolidated Financial Statements.

The chief operating decision maker (“CODM”) is our Chairman and Chief Executive Officer. The CODM regularly receives certain segment information, including net interest income, noninterest income, significant noninterest expenses, and income or loss from operations before income taxes. This information is used to evaluate performance and allocate resources for each segment.

The following schedule presents selected operating segment information that is regularly provided to the CODM to evaluate performance and allocate resources for the three months ended September 30, 2025 and 2024:

1 Interest income is shown net of interest expense consistent with the information regularly provided to the CODM and used to evaluate segment performance.

2 Includes expenses such as professional and legal services, marketing and business development, deposit insurance and regulatory expense, credit-related expense, other real estate expense, and other noninterest expense.

The following schedule presents selected operating segment information that is regularly provided to the CODM to evaluate performance and allocate resources for the nine months ended September 30, 2025 and 2024:
