The following table includes NII sensitivity results as of September 30, 2026 and 2025:

Table 31: Net Interest Income Sensitivity Analysis

(a)The effect on NII in the first year from a 100 basis point increase is approximately one third of the disclosed result for the 200 basis point scenario. The impact of a 100 basis point decrease is approximately neutral.

When forecasting NII, we make certain key assumptions that can materially impact the resulting sensitivities, including the following:

Future Balance Sheet Composition: Our balance sheet composition is dynamic and based on our forecasted expectations. The projected balance sheet composition by the end of year one is generally consistent with the spot composition at September 30, 2026.

Balance Sheet Forecast: Our balance sheet forecast is based on various assumptions that include key interest rate risk aspects such as loan and deposit growth, as well as mix, and is consistent with our guidance.

Deposit Betas: Deposit pricing changes are primarily driven by changes in the Federal Funds rate. We define the deposit beta as the change in deposit rate paid on total interest-bearing deposits since August 2026 divided by the change in the upper level of the average stated Federal Funds rate range since August 2026, the end of the prior rate cycle. For interest rate risk modeling, PNC uses dynamic beta models to adjust assumed repricing sensitivity depending on market rate levels as well as other factors. The dynamic beta assumptions reflect historical experience as well as future expectations, and are periodically updated to reflect the current view of future expectations. Actual deposit rates paid may differ from modeled projections due to variables such as competition for deposits and customer behavior.

Asset Prepayments: PNC includes prepayment assumptions for both loan and investment portfolios. Mortgage and home equity portfolios utilize an industry standard model to drive estimated prepayments that increase in lower rate environments. Commercial and other consumer loan portfolios assume static constant prepayment rates that are consistent across rate scenarios, as those portfolios historically do not exhibit significantly different prepayment behaviors based upon the level of market rates.

Impact of Derivatives: As part of our risk management strategy, PNC uses interest rate derivatives, some of which are forward starting, to hedge floating rate commercial loans. PNC had $82.6 billion in active and forward starting receive fix / pay float swaps used to hedge floating rate commercial loans as of September 30, 2026, with a weighted average duration of 2.3 years and an average fixed rate of 3.92%. Additionally, PNC utilizes receive fix / pay float swaps to hedge fixed rate debt, as well as pay fix / receive float swaps to hedge the investment securities portfolio. See Note 13 Financial Derivatives for additional information on how we use derivatives to hedge these financial instruments.
