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.

13 Impact of Noninterest-bearing (NIB) Demand Deposits The increased value of noninterest-bearing deposits has exceeded the decline in volume Average Noninterest-bearing Demand Impact of NIB on NIM 1 Noninterest-bearing demand deposits have declined as interest rates have risen, though the value of these deposits has increased overall  The value of noninterest-bearing funds presented in this chart reflects the impact these funds have on net interest margin  Noninterest-bearing deposits have declined $14 billion or 35% from a peak of $41 billion in 2Q22  In 4Q23, noninterest-bearing funds added 114 basis points to the net interest margin, compared to 7 bp in 2Q22 and 48 basis points in 4Q22 ($ billions) $40.9 $41.1 $39.6 $38.0 $34.4 $29.8 $27.9 $26.9 0.06% 0.07% 0.21% 0.48% 0.83% 1.06% 1.13% 1.14% $0.0 $10.0 $20.0 $30.0 $40.0 $50.0 1Q22 2Q22 3Q22 4Q22 1Q23 2Q23 3Q23 4Q23 (1) The impact of noninterest-bearing sources of funds on the net interest margin is calculated as the difference between interest earning assets and interest-bearing liabilities divided by earnings assets multiplied by rate paid on interest-bearing liabilities.

Net Interest Income – Outlook & Rate Sensitivity 16 Active balance sheet management has stabilized net interest income in 2023 and has positioned us for future growth (1) Assumes no change in the size or composition of the earning assets excluding derivative hedge activity, while it assumes a change in composition of deposits (a lesser proportion of noninterest-bearing relative to total deposits) (2) This analysis suggest latent interest rate sensitivity of +1.2%, 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 of +1.2% which reflects changes to NII based upon future rate movements implied by the forward rate curve at 12/31/2023. 1.0% 2.4% 3.9% -100 Implied +100 bps 4Q23 vs. 4Q24 Net Interest Income Sensitivity Sensitivity of net interest income to interest rates has evolved over the past year  The composition of funding, including deposits, has transitioned toward higher beta products (more rate sensitivity)  Changing balance sheet rate sensitivity has been actively managed through interest rate swaps and funding strategies The rapidly changing interest rate environment requires a more dynamic view of interest rate sensitivity  The chart shows expected net interest income change, relative to 4Q23, for the yield curve implied forward path in rates at the end of 2023 (Fed Funds Target ends 2024 at 3.75%) 1  Holding other things constant, net interest income would increase 2.4%2  +100 and -100 parallel interest rate shocks to this forward rate path illustrate moderate rate sensitivity Net interest income in 4Q24 is expected to be stable to slightly increasing when compared to 4Q23 The balance sheet is positioned for net interest income growth, particularly if short-term rates fall faster than long-term rates

Interest Rate Sensitivity – Net Interest Income Sensitivity Analysis 29 Standard parallel rate shocks suggest asset sensitivity, however, the rate path implied by the forward curve reveals liability sensitivity if short-term rates fall faster than long-term rates (1) 12-month forward simulated impact of an instantaneous and parallel change in interest rates and assumes no change in the size or composition of the earning assets excluding derivative hedge activity, while it assumes a change in composition of deposits (a lesser proportion of noninterest-bearing relative to total deposits). (2) Latent interest rate sensitivity refers to future changes in Net Interest Income (“NII”) based upon past rate movements that have yet to be fully realized in revenue; Emergent interest rate sensitivity refers to changes to NII based upon future rate movements implied by the forward rate curve at 12/31/2023. Based on the yield curve implied forward path in rates at the end of 2023 (Fed Funds Target ends 2024 at 3.75%), net interest income would increase 2.4% in 4Q24 vs. 4Q23: Latent(2) sensitivity: NII estimated to decrease by approximately 1.2% in 4Q24 This reflects a total deposit cost increase of approximately 70 basis points by 3Q24 which is consistent with a 50% through-the-cycle beta Emergent (2) sensitivity: NII estimated to increase by approximately 1.2%, in addition to Latent, in 4Q24 This estimate does not include any changes to the size or composition of earning assets; it reflects existing swap maturities and forward-starting swaps • Asset duration is being managed to reflect emerging liability duration.
