The following table provides details on the contractual maturity ranges and interest sensitivity of our loan classes at December 31, 2024.

Table 24: Selected Loan Maturities and Interest Sensitivity

Our determination of the ACL is based on historical loss and performance experience, current economic conditions, the reasonable and

supportable forecasts of future economic conditions and other relevant factors, including current borrower and/or transaction characteristics and assessments of the remaining estimated contractual term as of the balance sheet date. We maintain the ACL at an appropriate level for expected losses on our existing investment securities, loans, equipment finance leases, other financial assets and unfunded lending related commitments.

Expected losses are estimated primarily using a combination of (i) the expected losses over a reasonable and supportable forecast period, (ii) a period of reversion to long run average expected losses, where applicable and (iii) long run average expected losses for the remaining estimated contractual term.

We use forward-looking information in estimating expected credit losses for our reasonable and supportable forecast period. For this purpose, we have established a framework which includes a three-year forecast period and the use of four economic scenarios and associated probability weights, which in combination create a forecast of expected economic outcomes. Forward-looking information, such as forecasted relevant macroeconomic variables, is incorporated into the expected credit loss estimates using quantitative macroeconomic models, as well as through analysis from PNC’s economists and management’s judgment.

The reversion period is used to bridge our three-year reasonable and supportable forecast period and the long-run average expected credit losses. We consider a number of factors in determining the duration of the reversion period, such as contractual maturity of the asset, observed historical patterns and the estimated credit loss rates at the end of the forecast period relative to the beginning of the long run average period. The reversion period is typically 1-3 years, if not immediate.

The long-run average expected credit losses are derived from available historical credit information. We use long-run average expected losses for the portfolio over the estimated remaining contractual term beyond our reasonable and supportable forecast period and the reversion period.

The following discussion provides additional information on our reserves for loans and leases as well as unfunded lending related commitments. See Note 1 Accounting Policies for further discussion on our ACL, including details of our methodologies and discussion of the allowances for investment securities and other financial assets. See also the Critical Accounting Estimates and Judgments section of this Report for further discussion of the assumptions used in the determination of the ACL as of December 31, 2024.

Allowance for Loan and Lease Losses

Our pooled expected credit loss methodology is based upon the quantification of PD, LGD, EAD and the remaining estimated contractual term for a loan, loan segment or lease. We also consider the impact of prepayments and amortization on the estimated contractual term in our expected loss estimates. We use historical data, current borrower characteristics and forecasted economic

66 The PNC Financial Services Group, Inc. –2024 Form 10-K variables in quantitative methods to estimate these risk parameters by loan, loan segment or lease. PD represents a quantification of risk of the likelihood that a borrower may not be able to pay their contractual obligation over a defined period of time. LGD describes the estimated magnitude of potential loss if a borrower were to default, and EAD (or utilization rates for certain revolving loans) is the estimated balance outstanding at the expected time of default. These parameters are calculated for each forecasted scenario and the long-run average period, and are combined to generate expected loss estimates by scenario in proportion to the scenario weights.

For loans and leases that do not share similar risk characteristics with a pool of loans, we establish individually assessed reserves using methods prescribed by GAAP. Reserves for individual commercial nonperforming loans exceeding a defined dollar threshold are based on an analysis of the present value of the loan’s expected future cash flows or the fair value of the collateral, if appropriate under our policy for collateral dependent loans. Commercial nonperforming loans that are below the defined threshold are collectively reserved for, as we believe these loans continue to share similar risk characteristics. For consumer nonperforming loans classified as collateral dependent, charge-off and ALLL related to recovery of amounts previously charged-off are evaluated through an analysis of the fair value of the collateral less costs to sell.

While our reserve models and methodologies strive to reflect all relevant expected credit risk factors, there continues to be uncertainty associated with, but not limited to, potential imprecision in the estimation process due to the inherent time lag of obtaining information and normal variations between expected and actual outcomes. We may hold additional reserves that are designed to provide coverage for losses attributable to such risks. A portion of the allowance is related to qualitative measurement factors. These factors may include, but are not limited to:

•Industry concentrations and conditions,

•Changes in market conditions, including regulatory and legal requirements,

•Changes in the nature and volume of our portfolio,

•Recent credit quality trends,

•Recent loss experience in particular portfolios, including specific and unique events,

•Recent macroeconomic factors that may not be reflected in the forecast information,

•Limitations of available input data, including historical loss information and recent data such as collateral values,

•Model imprecision and limitations,

•Changes in lending policies and procedures, including changes in loss recognition and mitigation policies and procedures, and

•Timing of available information.

Allowance for Unfunded Lending Related Commitments

We maintain the allowance for unfunded lending related commitments on off-balance sheet credit exposures that are not unconditionally cancelable, (e.g., unfunded loan commitments, letters of credit and certain financial guarantees) at a level we believe is appropriate as of the balance sheet date to absorb expected credit losses on these exposures. Other than the estimation of the probability of funding, this reserve is estimated in a manner similar to the methodology used for determining reserves for pooled loans and leases. The allowance for unfunded lending related commitments is recorded as a liability on the Consolidated Balance Sheet. Net adjustments to this reserve are included in the provision for credit losses on the Consolidated Income Statement.
