1. BASIS OF PRESENTATION

The accompanying unaudited consolidated financial statements of Zions Bancorporation, National Association and its majority-owned subsidiaries (collectively “Zions Bancorporation, N.A.,” “the Bank,” “we,” “our,” “us”) 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 adjustments (consisting of normal recurring accruals) 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 (“ASC”).

The results of operations for the three months ended March 31, 2024 and 2023 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 financial statements and accompanying Notes. Actual results could differ from those estimates. For further information, refer to the consolidated financial statements and accompanying footnotes included in our 2023 Form 10-K.

We evaluated events that occurred between March 31, 2024 and the date the accompanying financial statements were issued, and determined that there were no material events that would require adjustments to our consolidated financial statements or significant disclosure in the accompanying Notes.

Zions Bancorporation, N.A. is a commercial 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 bank divisions, which we refer to as “affiliates,” or “affiliate banks,” each with its own local branding and management team. These include 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 name The Commerce Bank of Oregon in Oregon.

2. RECENT ACCOUNTING PRONOUNCEMENTS

3. FAIR VALUE

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an 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 and the fair value hierarchy, see Note 3 of our 2023 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”) relate to the portion of our Small Business Investment Company (“SBIC”) investments that are publicly traded.

1 The Level 1 PEIs relate to the portion of our SBIC investments that are publicly traded.

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 2023 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, including impaired loans that have been measured based on 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 include changes in value resulting from observable price changes for equity investments without readily determinable fair values, write-downs of individual assets, or the application of lower of cost or fair value accounting. At March 31, 2024, we had $2 million of collateral-dependent loans classified in Level 2, and we recognized less than $1 million of losses from fair value changes related to these loans. For additional information regarding assets and liabilities measured at fair value on a nonrecurring basis, see Note 3 of our 2023 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 does not include 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 within the scope of this disclosure, and the methods and significant assumptions used to estimate their fair value, see Note 3 of our 2023 Form 10-K.

4. OFFSETTING ASSETS AND LIABILITIES

The following schedules present gross and net information for selected financial instruments on the balance sheet:

Security repurchase and reverse repurchase agreements are offset, when applicable, on the balance sheet according to master netting agreements. Security repurchase agreements are included in “Federal funds and other short-term borrowings” on the consolidated balance sheet. Derivative instruments may be offset under their master netting agreements; however, for accounting purposes, we present these items on a gross basis on our balance sheet. See Note 7 for further information regarding derivative instruments.

5. INVESTMENTS

Investment Securities

Investment securities are classified as held-to-maturity (“HTM”), available-for-sale (“AFS”), or trading. HTM securities, which management has the intent and ability to hold until maturity, are carried at amortized cost. The amortized cost amounts represent the original cost of the investments, adjusted for related amortization or accretion of any purchase premiums or discounts, and for any impairment losses, including credit-related impairment. AFS securities are carried at fair value, and changes in fair value (unrealized gains and losses) are reported as net increases or decreases to accumulated other comprehensive income (“AOCI”), net of related taxes. Trading securities are carried at fair value with gains and losses recognized in current period earnings.

The carrying values of our securities do not include accrued interest receivables of$58 million and $65 million at March 31, 2024 and December 31, 2023, respectively. These receivables are included in “Other assets” on the consolidated balance sheet.

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, and 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 AOCI will offset the effect of the amortization of the premium or discount in interest income that is created by the transfer. The discount associated with securities previously transferred from AFS to HTM was $2.0 billion ($1.5 billion after tax) at March 31, 2024.

See Notes 3 and 5 of our 2023 Form 10-K for more information regarding our process to estimate the fair value and accounting for our investment securities, respectively. The following schedule presents the amortized cost and estimated fair values of our HTM and AFS securities:

1 Gross unrealized gains for the respective AFS security categories were individually less than $1 million.

Maturities

The following schedule presents the amortized cost and weighted average yields of debt securities by contractual maturity of principal payments at March 31, 2024. This schedule does not reflect the duration of the portfolio, which would incorporate amortization, expected prepayments, interest rate resets, and fair value hedges; the effects of which result in measured durations shorter than contractual maturities.

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

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

At March 31, 2024 and December 31, 2023, approximately 2,940 and 2,998 AFS investment securities were in an unrealized loss position, respectively.

Impairment

On a quarterly basis, we review our investment securities portfolio for the presence of impairment on an individual security basis. For additional information on our policy and impairment evaluation process for investment securities, see Note 5 of our 2023 Form 10-K.

AFS Impairment

We did not recognize any impairment on our AFS investment securities portfolio during the first three months of 2024. Unrealized losses primarily relate to higher interest rates subsequent to the purchase of securities and are not attributable to credit; as such, absent any future sales, we would expect to receive the full principal value at maturity. At March 31, 2024, we had not initiated any sales of AFS securities, nor did we have an intent to sell any identified securities with unrealized losses. We do not believe it is more likely than not that we would be required to sell such securities before recovery of their amortized cost basis.

HTM Impairment

For HTM securities, the allowance for credit losses (“ACL”) is assessed consistent with the approach described in Note 6 for loans and leases measured at amortized cost. At March 31, 2024, the ACL on HTM securities wasless than $1 million, all HTM securities were risk-graded as“Pass” in terms of credit quality, and none were considered past due.

Securities Gains and Losses Recognized in Income

The following schedule presents securities gains and losses recognized in income:

1 Net gains (losses) were recognized in “Securities gains (losses), net” on the consolidated statement of income.

The following schedule presents interest income by security type:

6. LOANS, LEASES, AND ALLOWANCE FOR CREDIT LOSSES

Loans, Leases, and Loans Held for Sale

Loans and leases are summarized as follows according to major portfolio segment and specific loan class:

Loans and leases are measured and presented at their amortized cost basis, which includes net unamortized purchase premiums, discounts, and deferred loan fees and costs totaling $32 million and $37 million at March 31, 2024 and December 31, 2023, respectively. Amortized cost basis does not include accrued interest receivables of $300 million and $299 million at March 31, 2024 and December 31, 2023, respectively. These receivables are presented in the consolidated balance sheet within the “Other assets” line item.

Municipal loans generally include loans to state and local governments (“municipalities”) with the debt service being repaid from general funds or pledged revenues of the municipal entity, or to private commercial entities or 501(c)(3) not-for-profit entities utilizing a pass-through municipal entity to achieve favorable tax treatment.

Land acquisition and development loans included in the construction and land development loan portfolio were $237 million at March 31, 2024 and $219 million at December 31, 2023.

Loans with a carrying value of $38.7 billion at March 31, 2024 and $36.3 billion at December 31, 2023 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.

At the time of origination, we determine the classification of loans as either held for investment or held for sale. Loans held for sale are measured at fair value or the lower of cost or fair value and primarily consist of (1) commercial real estate (“CRE”) loans that are sold into securitization entities, and (2) conforming residential mortgages that are 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 the sold loans in the form of servicing rights or guarantees. The principal balance of sold loans for which we retain servicing was $0.5 billion and $0.4 billion at March 31, 2024 and December 31, 2023, respectively. Income from sold loans, excluding servicing, was $1 million for the three months ended March 31, 2024, and $5 million for the three months ended March 31, 2023. Other income from loans sold includes fair value adjustments on loans that are included in “Capital markets fees” on the consolidated statement of income.

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 2023 Form 10-K.

The ACL for AFS and HTM debt securities is estimated separately from loans. For HTM securities, the ACL is estimated consistent with the approach for loans measured at amortized cost. See Note 5 of our 2023 Form 10-K for further discussion of our methodology used to estimate the ACL on AFS and HTM debt securities.

Changes in the ACL are summarized as follows:

Nonaccrual Loans

Loans are generally placed on nonaccrual status when payment in full of principal and interest is not expected, or the loan is 90 days or more past due as to principal or interest, unless the loan is both well-secured and in the process of collection. Factors we consider in determining whether a loan is placed on nonaccrual include delinquency status, collateral value, borrower or guarantor financial statement information, bankruptcy status, and other information which would indicate that the full and timely collection of interest and principal is uncertain.

A nonaccrual loan may be returned to accrual status when (1) all delinquent interest and principal become current in accordance with the terms of the loan agreement, (2) the loan, if secured, is well-secured, (3) the borrower has paid according to the contractual terms for a minimum of six months, and (4) an analysis of the borrower indicates a reasonable assurance of the borrower's ability and willingness to maintain payments.

The amortized cost basis of nonaccrual loans is summarized as follows:

For accruing loans, interest is accrued and interest payments are recognized into interest income according to the contractual loan agreement. For nonaccruing loans, the accrual of interest is discontinued, any uncollected or accrued interest is reversed from interest income in a timely manner (generally within one month), and any payments received on these loans are not recognized into interest income, but are applied as a reduction to the principal outstanding. When the collectability of the amortized cost basis for a nonaccrual loan is no longer in doubt, then interest payments may be recognized in interest income on a cash basis. For the three months ended March 31, 2024 and 2023, there wasno interest income recognized on a cash basis during the period the loans were on nonaccrual.

The amount of accrued interest receivables reversed from interest income during the periods presented is summarized by loan portfolio segment as follows:

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 are consistent with published definitions of regulatory risk classifications.

•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 deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in 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 of the collateral pledged, if any. Assets so classified 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 balance of loans classified as Doubtful was $5 million at March 31, 2024, compared with zero at December 31, 2023.

For consumer loans and for CRE loans with commitments greater than $1 million, we generally assign internal risk grades similar to those described previously based on automated rules that depend on refreshed credit scores, payment performance, and other risk indicators. These 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. The schedule also summarizes the current period gross charge-offs by year of origination.

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 according to their modified terms. The amortized cost of modified loans that had a payment default during the three months ended March 31, 2024 and 2023, which were still in default at period end, and were within 12 months or less of being modified was approximately $18 million, primarily commercial real estate loans, and less than $1 million, respectively.

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 $3 million and $8 million at March 31, 2024 and March 31, 2023, 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.

Loan modifications to borrowers experiencing financial difficulty during the three months ended March 31, 2024 and 2023 did not result in principal forgiveness for any class of loan for each respective period.

The following schedule presents the aging of loans to borrowers experiencing financial difficulty that were modified on or after April 1, 2023 through March 31, 2024, 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 January 1, 2023, the date we adopted ASU 2022-02, through March 31, 2023, 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 less than $1 million at March 31, 2024, compared with zero at December 31, 2023. The amortized cost basis of consumer mortgage loans collateralized by residential real estate property that were in the process of foreclosure was $11 million for both periods.

7. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Objectives and Accounting

Our primary objective for using derivatives is to manage interest rate risk. We use derivatives to stabilize forecasted interest income from variable-rate assets and to modify the coupon or the duration of fixed-rate financial assets or liabilities. We also assist clients with their risk management needs through the use of derivatives. Cash receipts and payments from derivatives designated in qualifying hedging relationships are classified in the same category as the cash flows from the items being hedged in the statement of cash flows, and cash flows from undesignated derivatives are classified as operating activities. For a more detailed discussion of the use of and accounting policies regarding derivative instruments, see Note 7 of our 2023 Form 10-K.

Fair Value Hedges of Liabilities – During the second quarter of 2023, we terminated our remaining receive-fixed interest rate swap with a notional amount of $500 million that had been designated in a qualifying fair value hedge relationship of fixed-rate debt. The receive-fixed interest rate swap effectively converted the interest on our fixed-rate debt to floating until it was terminated. Prior to termination, changes in the fair value of derivatives designated as fair value hedges of debt were offset by changes in the fair value of the hedged debt instruments as shown in the schedules on the following pages. The unamortized hedge basis adjustments resulting from the terminated hedging relationship will be amortized over the remaining life of the fixed-rate debt.

Fair Value Hedges of Assets– Fair value hedges of fixed-rate assets effectively convert the fixed interest income to a floating rate on the hedged portion of the assets. Changes in fair value of derivatives designated as fair value hedges of fixed-rate financial assets were largely offset by changes in the value of the hedged assets, as shown in the schedules on the following pages. At March 31, 2024, we had pay-fixed, receive-floating interest rate swaps with an aggregate notional amount of $3.6 billion designated as fair value hedges of fixed-rate AFS securities. We had an additional $1.0 billion of aggregate notional designated as hedges of fixed-rate commercial loans.

Cash Flow Hedges – Cash flow hedges of variable-rate assets and liabilities effectively convert the variable interest receipts and payments to fixed. At March 31, 2024, we had receive-fixed interest rate swaps with an aggregate notional amount of $850 million designated as cash flow hedges of pools of floating-rate commercial loans. Additionally, at March 31, 2024, we had one pay-fixed interest rate swap with a notional amount of $500 million designated as a cash flow hedge of the variability in the interest payments on certain FHLB advances. Changes in the fair value of qualifying cash flow hedges during the quarter were recorded in AOCI as shown in the schedule below. The amounts deferred in AOCI are reclassified into earnings in the periods in which the hedged interest receipts or payments occur (i.e., when the hedged forecasted transactions affect earnings). At March 31, 2024, there was $173 million of losses deferred in AOCI related to terminated cash flow hedges that are expected to be fully amortized by October 2027.

Collateral and Credit Risk

Exposure to credit risk arises from the possibility of nonperformance by counterparties. No significant losses on derivative instruments have occurred as a result of counterparty nonperformance. For more information on how we incorporate counterparty credit risk in derivative valuations, see Note 3 of our 2023 Form 10-K. For additional discussion of collateral and the associated credit risk related to our derivative contracts, see Note 7 of our 2023 Form 10-K.

Our derivative contracts require us to pledge collateral for derivatives that are in a net liability position at a given balance sheet date. Certain of these derivative contracts contain credit risk-related contingent features that include the requirement to maintain a minimum debt credit rating. We may be required to pledge additional collateral if a credit risk-related feature were triggered, such as a downgrade of our credit rating. In past situations, counterparties have not generally demanded that additional collateral be pledged when provided for by the contractual terms. At March 31, 2024, the fair value of our derivative liabilities was $388 million, for which we were required to pledge cash collateral of less than $1 million in the normal course of business. If our credit rating were downgraded one notch by either Standard & Poor’s (“S&P”) or Moody’s at March 31, 2024, there would likely beno additional collateral required to be pledged.

Derivative Amounts

The following schedule presents information regarding notional amounts and recorded gross fair values at March 31, 2024 and December 31, 2023, and the related gain (loss) of derivative instruments:

1 Customer interest rate derivatives include both customer-facing derivatives as well as offsetting derivatives facing other dealer banks. The fair value of these derivatives include a net credit valuation adjustment of $9 million, reducing the fair value of the liability at both March 31, 2024, and December 31, 2023.

The amount of derivative gains (losses) from cash flow and fair value hedges that were deferred in other comprehensive income (“OCI”) or recognized in earnings for the three and three months ended March 31, 2024 and 2023 is presented in the schedules below.

1 For the 12 months following March 31, 2024, we estimate that $102 million of losses will be reclassified from AOCI into interest income, compared with an estimate of $156 million of losses at March 31, 2023.

2 At March 31, 2024, the total cumulative unamortized basis adjustment for terminated fair value hedges of debt was $45 million. We didnot have any cumulative unamortized basis adjustment for terminated fair value hedges of debt at March 31, 2023. We had $3 million and $10 million of cumulative unamortized basis adjustments from terminated fair value hedges of assets at March 31, 2024 and 2023, respectively. Interest on fair value hedges presented above include the amortization of the remaining unamortized basis adjustments.

The amount of gains (losses) recognized from derivatives not designated as accounting hedges is summarized as follows:

The following schedule presents derivatives used in fair value hedge accounting relationships, as well as pre-tax gains/(losses) recorded on such derivatives and the related hedged items for the periods presented:

1 Consists of hedges of benchmark interest rate risk of fixed-rate long-term debt, fixed-rate AFS securities, and fixed-rate commercial loans. Gains and losses were recorded in net interest expense or income 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 provides information regarding basis adjustments for hedged items:

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 These amounts include the amortized cost basis of defined portfolios of AFS securities and commercial loans used to designate hedging relationships in which the hedged item is the stated amount of assets in the defined portfolio anticipated to be outstanding for the designated hedged period. At March 31, 2024, the amortized cost basis of the defined portfolios used in these hedging relationships was $11.0 billion; the cumulative basis adjustment associated with these hedging relationships was $50.5 million; and the notional amounts of the designated hedging instruments were $3.5 billion.

8. LEASES

We have operating and finance leases for branches, corporate offices, and data centers. At March 31, 2024, we had 408 branches, of which 278 are owned and 130 are leased. We lease our headquarters in Salt Lake City, Utah. The remaining maturities of our lease commitments range from the year 2024 to 2062, and some lease arrangements include options to extend or terminate the leases.

All leases with lease terms greater than twelve months are reported as a lease liability with a corresponding right-of-use (“ROU”) asset. We present ROU assets for operating leases and finance leases on the consolidated balance sheet in “Other assets,” and “Premises, equipment and software, net,” respectively. The corresponding liabilities for those leases are presented in “Other liabilities,” and “Long-term debt.” For more information about our lease policies, see Note 8 of our 2023 Form 10-K.

The following schedule presents ROU assets and lease liabilities with 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 Contractual maturities for the nine months remaining in 2024.

We enter into certain lease agreements where we are the lessor of real estate. Real estate leases are made from bank-owned and subleased property to generate cash flow from the property, including from leasing vacant suites in which we occupy portions of the building. Operating lease income was $3 million for both the first quarter of 2024 and 2023.

We originated equipment leases, considered to be sales-type leases or direct financing leases, totaling $388 million and $383 million at March 31, 2024 and December 31, 2023, respectively. We recorded income of $4 million on these leases for both the first quarter of 2024 and 2023.

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 basis adjustments for interest rate swaps designated as fair value hedges.

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

LONG-TERM DEBT

1 The change in the subordinated notes balance is primarily due to a fair value hedge accounting adjustment. 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 March 31, 2024, there were 147.7 million shares of$0.001 par value common stock outstanding. Common stock and additional paid-in capital decreased $26 million, or 2%, to $1.7 billion at March 31, 2024, from December 31, 2023, primarily due to common stock repurchases. During the first quarter of 2024, we repurchased 0.9 million common shares outstanding for $35 million at an average price of $39.32 per share.

The AOCI balance was a loss of $2.6 billion at March 31, 2024, and primarily reflects the decline in the fair value of fixed-rate investment securities as a result of higher interest rates, and includes $2.0 billion ($1.5 billion after tax) of unrealized losses on the 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

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

1 Net of participations.

2 Represents agreements with Farmer Mac to purchase securities backed by certain agricultural mortgage loans.

For more information about these commitments and guarantees including their terms and collateral requirements, see Note 16 of our 2023 Form 10-K.

Legal Matters

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

At March 31, 2024, we were subject to the following material litigation:

•Two civil cases, Lifescan Inc. and Johnson & Johnson Health Care Services v. Jeffrey 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. The cases are in the late stages of discovery. No trial has been set.

•Sipple v. Zions Bancorporation, N.A., brought against us in the District Court of Clark County, Nevada in February 2021 with respect to foreign transaction fees. This case is in the discovery phase and trial has been scheduled for October 2024. The parties are currently engaged in settlement discussions.

At least quarterly, we review outstanding and new legal matters, utilizing then-available information. In accordance with applicable accounting guidance, if we determine that a loss from a matter is probable and the amount of the loss can be reasonably estimated, we establish an accrual for the loss. In the absence of such a determination, no accrual is made. Once established, accruals are adjusted to reflect developments relating to the matters.

In our review, we also assess whether we can determine the range of reasonably possible losses for significant matters in which we are unable to determine that the likelihood of a loss is remote. Because of the difficulty of predicting the outcome of legal matters, discussed subsequently, we are able to meaningfully estimate such a range only for a limited number of matters. Based on information available at March 31, 2024, we estimated that the aggregate range of reasonably possible losses for those matters to be from zero to approximately $10 million in excess of amounts accrued. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from this estimate. Those matters for which a meaningful estimate is not possible are not included within this estimated range and, therefore, this estimated range does not represent our maximum loss exposure.

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

Any estimate or determination relating to the future resolution of litigation, arbitration, governmental or self-regulatory examinations, investigations or actions 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 well articulated, reviewed, analyzed, and vetted through discovery, preparation for trial or hearings, substantive and productive mediation or settlement discussions, or other actions. It is also particularly true with respect to class action and similar claims involving multiple defendants, matters with complex procedural requirements or substantive issues or novel legal theories, and examinations, investigations and other actions conducted or brought by governmental and self-regulatory agencies, in which the normal adjudicative process is not applicable. Accordingly, we usually are 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. Accordingly, our judgments and estimates relating to claims will change from time to time in light of developments and actual outcomes will differ from our estimates. These differences may be material.

11. REVENUE RECOGNITION

We derive our revenue primarily from interest income on loans and securities. Only noninterest income is considered to be revenue from contracts with customers in scope of ASC 606. For more information about our revenue recognition from contracts, see Note 17 of our 2023 Form 10-K.

Disaggregation of Revenue

The following schedule presents net revenue by operating business segment for the three months ended March 31, 2024 and 2023:

Revenue from contracts with customers did not generate significant contract assets and liabilities. Contract receivables are included in “Other assets” on the consolidated balance sheet. Payment terms vary by services offered, and the timing between completion of performance obligations and payment is generally not significant.

12. INCOME TAXES

The effective income tax rate was 24.6% for the first quarter of 2024, compared with 27.7% for the first quarter of 2023. The higher effective tax rate in the first quarter of 2023 was the result of a change in a discrete item that affected the reserve for uncertain tax positions. The tax rates during both periods were reduced by nontaxable municipal interest income and nontaxable income from certain bank-owned life insurance (“BOLI”), and were increased by the nondeductibility of Federal Deposit Insurance Corporation (“FDIC”) premiums, certain executive compensation plans, and other fringe benefits. The FDIC insurance premiums are nondeductible, whereas the FDIC special assessments are tax deductible.

At both March 31, 2024 and December 31, 2023, we had a net deferred tax asset (“DTA”) totaling $1.0 billion. The net DTA or DTL is included in either “Other assets” or “Other liabilities,” respectively, on the consolidated balance sheet.

We evaluate DTAs on a regular basis to determine whether a valuation allowance is required. In conducting this evaluation, we consider all available evidence, both positive and negative, based on the more-likely-than-not criteria that such assets will be realized. This evaluation includes, but is not limited to, the following:

•Future reversals of existing deferred tax liabilities (“DTLs”) — These DTLs have a reversal pattern generally consistent with DTAs and are used to realize the DTAs.

•Tax planning strategies — We have considered prudent and feasible tax planning strategies that we would implement to preserve the value of the DTAs, if necessary.

•Future projected taxable income — We expect future taxable income will offset the reversal of remaining net DTAs.

Based on this evaluation, we concluded that a valuation allowance was not required at both March 31, 2024 and December 31, 2023.

13. NET EARNINGS PER COMMON SHARE

Basic and diluted net earnings per common share based on the weighted average outstanding shares are summarized as follows:

The following schedule presents the weighted average stock awards that were anti-dilutive and not included in the calculation of diluted earnings per share:

14. OPERATING SEGMENT INFORMATION

We manage our operations with a primary focus on geographic area. We conduct our operations primarily through seven separately managed affiliate banks, each with its own local branding and management team, including 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 business segments. Performance assessment and resource allocation are based upon this geographic structure. Our affiliate banks are supported by an enterprise operating segment (referred to as the “Other” segment) that 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.

We allocate the cost of centrally provided services to the business segments based upon estimated or actual usage of those services. We also allocate capital based on the risk-weighted assets held at each business segment. We use an internal funds transfer pricing (“FTP”) allocation process to report results of operations for business segments. This process is subject to change and refinement over time. Total average loans and deposits presented for the business segments include insignificant intercompany amounts between business segments and may also include deposits with the “Other” segment.

At March 31, 2024, Zions Bank operated 95 branches in Utah,25 branches in Idaho, andone branch in Wyoming. CB&T operated 75 branches in California. Amegy operated 75 branches in Texas. NBAZ operated 56 branches in

Arizona. NSB operated 43 branches in Nevada. Vectra operated 34 branches in Colorado andone branch in New Mexico. TCBW operatedtwo branches in Washington andone branch in Oregon.

Transactions between business segments are primarily conducted at fair value, resulting in profits that are eliminated for reporting consolidated results of operations. The following schedule presents average loans, average deposits, and income before income taxes because we use these metrics when evaluating performance and making decisions pertaining to the business segments. The condensed statement of income identifies the components of income and expense which affect the operating amounts presented in the “Other” segment.

The following schedule presents selected operating segment information for the three months ended March 31, 2024 and 2023:
