Although the following list is not comprehensive, important factors that may cause material differences include: The quality and composition of our loan and securities portfolios and the quality and composition of our deposits; Changes in general industry, political and economic conditions, including elevated inflation, economic slowdown or recession, or other economic challenges; changes in interest and reference rates, which could adversely affect our revenue and expenses, the value of assets and liabilities, and the availability and cost of capital and liquidity; deterioration in economic conditions that may result in increased loan and leases losses; The effects of newly enacted and proposed regulations affecting us and the banking industry, as well as changes and uncertainties in applicable laws, and fiscal, monetary, regulatory, trade, and tax policies, and actions taken by governments, agencies, central banks, and similar organizations, including those that result in decreases in revenue; increases in bank fees, insurance assessments and capital standards; and other regulatory requirements; Competitive pressures and other factors that may affect aspects of our business, such as pricing and demand for our products and services, and our ability to recruit and retain talent; The impact of technological advancements, digital commerce, artificial intelligence, and other innovations affecting the banking industry; Our ability to complete projects and initiatives and execute on our strategic plans, manage our risks, control compensation and other expenses, and achieve our business objectives; Our ability to develop and maintain technology, information security systems and controls designed to guard against fraud, cybersecurity, and privacy risks; Our ability to provide adequate oversight of our suppliers or prevent inadequate performance by third parties upon whom we rely for the delivery of various products and services; Natural disasters, pandemics, catastrophic events and other emergencies and incidents and their impact on our and our customers’ operations and business and communities, including the increasing difficulty in, and the expense of, obtaining property, auto, business, and other insurance products; Governmental and social responses to environmental, social, and governance issues, including those with respect to climate change; Securities and capital markets behavior, including volatility and changes in market liquidity and our ability to raise capital; The possibility that our recorded goodwill could become impaired, which may have an adverse impact on our earnings and shareholders’ equity; The impact of bank closures or adverse developments at other banks on general investor sentiment regarding the stability and liquidity of banks; Adverse news and other expressions of negative public opinion whether directed at us, other banks, the banking industry, or otherwise that may adversely affect our reputation and that of the banking industry generally; Protracted congressional negotiations and political stalemates regarding government funding and other issues, including those that increase the possibility of government shutdowns, downgrades in United States (“U.S.”) credit ratings, or other economic disruptions; and The effects of wars and geopolitical conflicts, such as the ongoing war between Russia and Ukraine, the war in the Middle East, and other local, national, or international disasters, crises, or conflicts that may occur in the future. Factors that could cause our actual results, performance or achievements, industry trends, and results or regulatory outcomes to differ materially from those expressed or implied in the forward-looking statements are discussed in our 2023 Form 10-K and subsequent filings with the Securities and Exchange Commission (SEC) and are available on our website (www.zionsbancorporation.com) and from the SEC (www.sec.gov). We caution against the undue reliance on forward-looking statements, which reflect our views only as of the date they are made. Except to the extent required by law, we specifically disclaim any obligation to update any factors or to publicly announce the revisions to any forward-looking statements to reflect future events or developments. Use of Non-GAAP Financial Measures: This document contains several references to non-GAAP measures, including but not limited to, pre-provision net revenue and the “efficiency ratio,” which are common industry terms used by investors and financial services analysts. Certain of these non-GAAP measures are key inputs into Zions’ management compensation and are used in Zions’ strategic goals that have been and may continue to be articulated to investors. Therefore, the use of such non-GAAP measures are believed by management to be of substantial interest to the consumers of these financial disclosures and are used prominently throughout the disclosures. A reconciliation of the difference between such measures and GAAP financials is provided within the document, and users of this document are encouraged to carefully review this reconciliation.

SECURITIES & MONEY MARKET INVESTMENTS 13 The bank has strong on-balance sheet liquidity The investment portfolio is designed to be a storehouse of balance sheet liquidity • Principal and prepayment-related cash flows from securities were $840 million for the quarter • The composition of the investment portfolio allows for deep on- balance sheet liquidity through the repo market • Approximately 90% of securities are U.S. Government and U.S. Government Agency/GSE securities The investment portfolio is also used to balance interest rate risk • The estimated deposit duration at June 30, 2024 is assumed to be longer than the loan duration (including swaps); the investment portfolio brings balance to this mismatch • The estimated price sensitivity of the securities portfolio (including the impact of fair value hedges) is flat from prior year quarter at 3.7 percent Total Securities Portfolio and Money Market Investments (period-end balances) $21.6 $20.7 $20.7 $20.2 $19.6 $2.3 $3.1 $2.4 $2.6 $3.2 2Q23 3Q23 4Q23 1Q24 2Q24 Total Securities Money Market Investments 30% 30% 29% 28% 28% Percent of earning assets ($ billions)

NET INTEREST INCOME – OUTLOOK & RATE SENSITIVITY 14 Net interest income is expected to increase as asset repricing outpaces changes in funding costs Interest Rate Impacts on Net Interest Income1 (1) Assumes no change in the size or composition of the earning assets excluding derivative hedge activity but does assume a change in composition of deposits (a lesser proportion of noninterest- bearing relative to total deposits). (2) This analysis suggests latent interest rate sensitivity of 8.3%, which reflects future changes in net interest income (“NII”) based upon past rate movements that have yet to be fully realized in revenue, and emergent interest rate sensitivity reduces by 2.0% reflecting changes to NII based upon future rate movements implied by the forward rate curve at 6/30/2024. Net Interest Income Sensitivity 4.6% 6.3% 7.7% (100 bps) Implied +100 bps 2Q25 vs 2Q24 Reflects continued asset repricing, assumes total deposit cost increase of approximately 20 basis points by 2Q25 (assumes $3.5 billion of noninterest-bearing demand deposit migration to higher-cost products); 44% through- the-cycle total beta Latent2 Emergent2 Implied The estimated incremental impact of future rate changes from market implied rates is negative 200 basis points This assumes a Fed Funds Target of 4.50% at 2Q25 8.3% (2.0%) 6.3% Net interest income is expected to be slightly to moderately increasing in 2Q25 relative to 2Q24 -100 and +100 parallel interest rate shocks suggest moderate rate sensitivity between +4.6% and +7.7%
