FIFTH THIRD BANCORP

The Bancorp’s Consolidated Financial Statements are prepared in accordance with U.S. GAAP. Certain accounting policies require management to exercise judgment in determining methodologies, economic assumptions and estimates that may materially affect the Bancorp’s financial position, results of operations and cash flows. The Bancorp’s critical accounting policies include the accounting for the ALLL, reserve for unfunded commitments, valuation of servicing rights, fair value measurements, goodwill and legal contingencies.

As further discussed in Note 1 of the Notes to Consolidated Financial Statements, on January 1, 2023, the Bancorp adopted ASU 2022-02 (“Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures”). In conjunction with the adoption of this amended guidance, the Bancorp has revised its Critical Accounting Policies for the ALLL as described below. The accounting policy for the ALLL for periods prior to January 1, 2023 is provided in the Critical Accounting Policies Applicable Prior to January 1, 2023 section below. There have been no other material changes to the valuation techniques or models described below during the year ended December 31, 2023.

ALLL

The Bancorp disaggregates its portfolio loans and leases into portfolio segments for purposes of determining the ALLL. The Bancorp’s portfolio segments include commercial, residential mortgage and consumer. The Bancorp further disaggregates its portfolio segments into classes for purposes of monitoring and assessing credit quality based on certain risk characteristics. For an analysis of the Bancorp’s ALLL by portfolio segment and credit quality information by class, refer to Note 6 of the Notes to Consolidated Financial Statements.

The Bancorp maintains the ALLL to absorb the amount of credit losses that are expected to be incurred over the remaining contractual terms of the related loans and leases. Contractual terms are adjusted for expected prepayments but are not extended for expected extensions, renewals or modifications except in circumstances where extension or renewal options are embedded in the original contract and not unconditionally cancellable by the Bancorp. Accrued interest receivable on loans is presented in the Consolidated Financial Statements as a component of other assets. When accrued interest is deemed to be uncollectible (typically when a loan is placed on nonaccrual status), interest income is reversed. The Bancorp follows established policies for placing loans on nonaccrual status, so uncollectible accrued interest receivable is reversed in a timely manner. As a result, the Bancorp has elected not to measure a reserve for accrued interest receivable as part of its ALLL. However, the Bancorp does record a reserve for the portion of accrued interest receivable that it expects to be uncollectible. For additional information on the Bancorp’s accounting policies related to nonaccrual loans and leases, refer to Note 1 of the Notes to Consolidated Financial Statements.

Credit losses are charged and recoveries are credited to the ALLL. The ALLL is maintained at a level the Bancorp considers to be adequate and is based on ongoing quarterly assessments and evaluations of the collectability of loans and leases, including historical credit loss experience, current and forecasted market and economic conditions and consideration of various qualitative factors that, in management’s judgment, deserve consideration in estimating expected credit losses. Provisions for credit losses are recorded for the amounts necessary to adjust the ALLL to the Bancorp’s current estimate of expected credit losses on portfolio loans and leases. The Bancorp’s strategy for credit risk management includes a combination of conservative exposure limits significantly below legal lending limits and conservative underwriting, documentation and collections standards. The strategy also emphasizes diversification on a geographic, industry and customer level, regular credit examinations and quarterly management reviews of large credit exposures and loans experiencing deterioration of credit quality. Refer to the Credit Risk Management subsection of the Risk Management section of MD&A for additional information.

The Bancorp’s methodology for determining the ALLL requires significant management judgment and includes an estimate of expected credit losses on a collective basis for groups of loans and leases with similar risk characteristics and specific allowances for loans and leases which are individually evaluated.

Larger commercial loans and leases included within aggregate borrower relationship balances exceeding $1 million on nonaccrual status are individually evaluated for an ALLL. The Bancorp considers the current value of collateral, credit quality of any guarantees, the guarantor’s liquidity and willingness to cooperate, the loan or lease structure (including modifications, if any) and other factors when determining the amount of the ALLL. Other factors may include the borrower’s susceptibility to risks presented by the forecasted macroeconomic environment, the industry and geographic region of the borrower, size and financial condition of the borrower, cash flow and leverage of the borrower and the Bancorp’s evaluation of the borrower’s management. Significant management judgment is required when evaluating which of these factors are most relevant in individual circumstances, and when estimating the amount of expected credit losses based on those factors. When loans and leases are individually evaluated, allowances are determined based on management’s estimate of the borrower’s ability to repay the loan or lease given the availability of collateral and other sources of cash flow, as well as an evaluation of legal options available to the Bancorp. Allowances for individually evaluated loans and leases that are collateral-dependent are measured based on the fair value of the underlying collateral, less expected costs to sell where applicable. Allowances for individually evaluated loans and leases that are not collateral-dependent are typically measured based on the present value of expected cash flows of the loan or lease, discounted at its

56 Fifth Third Bancorp effective interest rate. Specific allowances on individually evaluated commercial loans and leases are reviewed quarterly and adjusted as necessary based on changing borrower and/or collateral conditions and actual collection and charge-off experience.

The Bancorp considers loans to be collateral-dependent when it becomes probable that repayment of the loan will be provided through the sale or operation of the collateral instead of from payments made by the borrower. The expected credit losses for these loans are typically estimated based on the fair value of the underlying collateral, less expected costs to sell where applicable. Specific allowances on individually evaluated consumer and residential mortgage loans are reviewed quarterly and adjusted as necessary based on changing borrower and/or collateral conditions and actual collection and charge-off experience.

Expected credit losses are estimated on a collective basis for loans and leases that are not individually evaluated. For collectively evaluated loans and leases, the Bancorp uses models to forecast expected credit losses based on the probability of a loan or lease defaulting, the expected balance at the estimated date of default and the expected loss percentage given a default. The estimate of the expected balance at the time of default considers prepayments and, for loans with available credit, expected utilization rates. The Bancorp’s expected credit loss models were developed based on historical credit loss experience and observations of migration patterns for various credit risk characteristics (such as internal credit risk ratings, external credit ratings or scores, delinquency status, loan-to-value trends, etc.) over time, with those observations evaluated in the context of concurrent macroeconomic conditions. The Bancorp developed its models from historical observations capturing a full economic cycle when possible.

The Bancorp’s expected credit loss models consider historical credit loss experience, current market and economic conditions, and forecasted changes in market and economic conditions if such forecasts are considered reasonable and supportable. Generally, the Bancorp considers its forecasts to be reasonable and supportable for a period of up to three years from the estimation date. For periods beyond the reasonable and supportable forecast period, expected credit losses are estimated by reverting to historical loss information without adjustment for changes in economic conditions. This reversion is phased in over a two-year period. The Bancorp evaluates the length of its reasonable and supportable forecast period, its reversion period and reversion methodology at least annually, or more often if warranted by economic conditions or other circumstances.

The Bancorp also considers qualitative factors in determining the ALLL. These considerations inherently require significant management judgment to determine the appropriate factors to be considered and the extent of their impact on the ALLL estimate. Qualitative factors are used to capture characteristics in the portfolio that impact expected credit losses but that are not fully captured within the Bancorp’s expected credit loss models. These include adjustments for changes in policies or procedures in underwriting, monitoring or collections, lending and risk management personnel and results of internal audit and quality control reviews. These may also include adjustments, when deemed necessary, for specific idiosyncratic risks such as geopolitical events, natural disasters and their effects on regional borrowers and changes in product structures. Qualitative factors may also be used to address the impacts of unforeseen events on key inputs and assumptions within the Bancorp’s expected credit loss models, such as the reasonable and supportable forecast period, changes to historical loss information or changes to the reversion period or methodology. When evaluating the adequacy of allowances, consideration is also given to regional geographic concentrations and the closely associated effect that changing economic conditions may have on the Bancorp’s customers.

Overall, the collective evaluation process requires significant management judgment when determining the estimation methodology and inputs into the models, as well as in evaluating the reasonableness of the modeled results and the appropriateness of qualitative adjustments. The Bancorp’s forecasts of market and economic conditions and the internal risk ratings assigned to loans and leases in the commercial portfolio segment are examples of inputs to the expected credit loss models that require significant management judgment. These inputs have the potential to drive significant variability in the resulting ALLL.

Refer to the Allowance for Credit Losses subsection of the Risk Management section of MD&A for a discussion on the Bancorp’s ALLL sensitivity analysis.

Reserve for Unfunded Commitments

The reserve for unfunded commitments is maintained at a level believed by management to be sufficient to absorb estimated expected credit losses related to unfunded credit facilities and is included in other liabilities in the Consolidated Balance Sheets. The determination of the adequacy of the reserve is based upon expected credit losses over the remaining contractual life of the commitments, taking into consideration the current funded balance and estimated exposure over the reasonable and supportable forecast period. This process takes into consideration the same risk elements that are analyzed in the determination of the adequacy of the Bancorp’s ALLL, as previously discussed. Net adjustments to the reserve for unfunded commitments are included in the provision for credit losses in the Consolidated Statements of Income.

Valuation of Servicing Rights

When the Bancorp sells loans through either securitizations or individual loan sales in accordance with its investment policies, it often obtains servicing rights. The Bancorp may also purchase servicing rights. The Bancorp has elected to measure all existing classes of its residential mortgage servicing rights at fair value at each reporting date with changes in the fair value of servicing rights reported in earnings in the period in which the changes occur. Servicing rights are valued using internal OAS models. Significant management judgment is necessary to identify key economic assumptions used in estimating the fair value of the servicing rights including the prepayment speeds of the underlying

57 Fifth Third Bancorp loans, the weighted-average life, the OAS and the weighted-average coupon rate, as applicable. The primary risk of material changes to the value of the servicing rights resides in the potential volatility in the economic assumptions used, particularly the prepayment speeds. In order to assist in the assessment of the fair value of servicing rights, the Bancorp obtains external valuations of the servicing rights portfolio from third parties and participates in peer surveys that provide additional confirmation of the reasonableness of the key assumptions utilized in the internal OAS model. For additional information on servicing rights, refer to Note 13 of the Notes to Consolidated Financial Statements.

Fair Value Measurements

The Bancorp measures certain financial assets and liabilities at fair value in accordance with U.S. GAAP, which defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Bancorp employs various valuation approaches to measure fair value including the market, income and cost approaches. The market approach uses prices or relevant information generated by market transactions involving identical or comparable assets or liabilities. The income approach involves discounting future amounts to a single present amount and is based on current market expectations about those future amounts. The cost approach is based on the amount that currently would be required to replace the service capacity of the asset.

U.S. GAAP establishes a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the instrument’s fair value measurement. For additional information on the fair value hierarchy and fair value measurements, refer to Note 1 of the Notes to Consolidated Financial Statements.

The Bancorp’s fair value measurements involve various valuation techniques and models, which involve inputs that are observable, when available. Valuation techniques and parameters used for measuring assets and liabilities are reviewed and validated by the Bancorp on a quarterly basis. Additionally, the Bancorp monitors the fair values of significant assets and liabilities using a variety of methods including the evaluation of pricing runs and exception reports based on certain analytical criteria, comparison to previous trades and overall review and assessments for reasonableness. The level of management judgment necessary to determine fair value varies based upon the methods used in the determination of fair value. Financial instruments that are measured at fair value using quoted prices in active markets (Level 1) require minimal judgment. The valuation of financial instruments when quoted market prices are not available (Levels 2 and 3) may require significant management judgment to assess whether quoted prices for similar instruments exist, the impact of changing market conditions including reducing liquidity in the capital markets and the use of estimates surrounding significant unobservable inputs. Table 5 provides a summary of the fair value of financial instruments carried at fair value on a recurring basis and the amounts of financial instruments valued using Level 3 inputs.

Refer to Note 28 of the Notes to Consolidated Financial Statements for further information on fair value measurements including a description of the valuation methodologies used for significant financial instruments.

Goodwill

Business combinations entered into by the Bancorp typically include the recognition of goodwill. U.S. GAAP requires goodwill to be tested for impairment at the reporting unit level on an annual basis, which the Bancorp performs as of September 30 each year, and more frequently if events or circumstances indicate that there may be impairment.

Impairment exists when a reporting unit’s carrying amount of goodwill exceeds its implied fair value. In testing goodwill for impairment, U.S. GAAP permits the Bancorp to first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. In this qualitative assessment, the Bancorp evaluates events and circumstances which may include, but are not limited to, the general economic environment, banking industry and market conditions, the overall financial performance of the Bancorp, the performance of the Bancorp’s common stock, the key financial performance metrics of the Bancorp’s reporting units and events affecting the reporting units to determine if it is not more likely than not that the fair value of a reporting unit is less than its carrying amount. If the quantitative impairment test is required or the decision to bypass the qualitative assessment is elected, the Bancorp performs the goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the carrying amount of the reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. A recognized impairment loss cannot be reversed in future periods even if the fair value of the reporting unit subsequently recovers.

58 Fifth Third Bancorp

The fair value of a reporting unit is the price that would be received to sell the unit as a whole in an orderly transaction between market participants at the measurement date. As none of the Bancorp’s reporting units are publicly traded, individual reporting unit fair value determinations cannot be directly correlated to the Bancorp’s stock price. The determination of the fair value of a reporting unit is a subjective process that involves the use of estimates and judgments, particularly related to cash flows, the appropriate discount rates and an applicable control premium. The determination of the fair value of the Bancorp’s reporting units includes both an income-based approach and a market-based approach. The income-based approach utilizes the reporting unit’s forecasted cash flows (including a terminal value approach to estimate cash flows beyond the final year of the forecast) and the reporting unit’s estimated cost of equity as the discount rate. Significant management judgment is necessary in the preparation of each reporting unit’s forecasted cash flows surrounding expectations for earnings projections, growth and credit loss expectations and actual results may differ from forecasted results. Additionally, the Bancorp determines its market capitalization based on the average of the closing price of the Bancorp’s stock during the month including the measurement date, incorporating an additional control premium, and compares this market-based fair value measurement to the aggregate fair value of the Bancorp’s reporting units in order to corroborate the results of the income approach. Refer to Note 10 of the Notes to Consolidated Financial Statements for further information regarding the Bancorp’s goodwill.

Legal Contingencies

The Bancorp and its subsidiaries are parties to numerous claims and lawsuits as well as threatened or potential actions or claims concerning matters arising from the conduct of its business activities. The outcome of claims or litigation and the timing of ultimate resolution are inherently difficult to predict and significant judgment may be required in the determination of both the probability of loss and whether the amount of the loss is reasonably estimable. The Bancorp’s estimates are subjective and are based on the status of legal and regulatory proceedings, the merit of the Bancorp’s defenses and consultation with internal and external legal counsel. An accrual for a potential litigation loss is established when information related to the loss contingency indicates both that a loss is probable and that the amount of loss can be reasonably estimated. Refer to Note 19 of the Notes to Consolidated Financial Statements for further information regarding the Bancorp’s legal proceedings.

Critical Accounting Policies Applicable Prior to January 1, 2023

The following paragraphs describe the portions of the Bancorp’s critical accounting policies that were applicable prior to January 1, 2023 but were updated in conjunction with the adoption of ASU 2022-02 on January 1, 2023. The following paragraphs do not include the portions of the respective policies that were not affected by the adoption of this new accounting standard. Refer to Note 1 of the Notes to Consolidated Financial Statements for additional information.

ALLL

The Bancorp maintains the ALLL to absorb the amount of credit losses that are expected to be incurred over the remaining contractual terms of the related loans and leases. Contractual terms are adjusted for expected prepayments but are not extended for expected extensions, renewals or modifications except in circumstances where the Bancorp reasonably expects to execute a TDR with the borrower or where certain extension or renewal options are embedded in the original contract and not unconditionally cancellable by the Bancorp. Accrued interest receivable on loans is presented in the Consolidated Financial Statements as a component of other assets. When accrued interest is deemed to be uncollectible (typically when a loan is placed on nonaccrual status), interest income is reversed. The Bancorp follows established policies for placing loans on nonaccrual status, so uncollectible accrued interest receivable is reversed in a timely manner. As a result, the Bancorp has elected not to measure a reserve for accrued interest receivable as part of its ALLL. However, the Bancorp does record a reserve for the portion of accrued interest receivable that it expects to be uncollectible.

Larger commercial loans and leases included within aggregate borrower relationship balances exceeding $1 million that exhibit probable or observed credit weaknesses, as well as loans that have been modified in a TDR, are individually evaluated for an ALLL. The Bancorp considers the current value of collateral, credit quality of any guarantees, the guarantor’s liquidity and willingness to cooperate, the loan or lease structure and other factors when determining the amount of the ALLL. Other factors may include the borrower’s susceptibility to risks presented by the forecasted macroeconomic environment, the industry and geographic region of the borrower, size and financial condition of the borrower, cash flow and leverage of the borrower and the Bancorp’s evaluation of the borrower’s management. Significant management judgment is required when evaluating which of these factors are most relevant in individual circumstances, and when estimating the amount of expected credit losses based on those factors. When loans and leases are individually evaluated, allowances are determined based on management’s estimate of the borrower’s ability to repay the loan or lease given the availability of collateral and other sources of cash flow, as well as an evaluation of legal options available to the Bancorp. Allowances for individually evaluated loans and leases that are collateral-dependent are measured based on the fair value of the underlying collateral, less expected costs to sell where applicable. Individually evaluated loans and leases that are not collateral-dependent are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate. The Bancorp evaluates the collectability of both principal and interest when assessing the need for a loss accrual. Specific allowances on individually evaluated commercial loans and leases, including TDRs, are reviewed quarterly and adjusted as necessary based on changing borrower and/or collateral conditions and actual collection and charge-off experience.

Consumer and residential mortgage loans that have been modified in a TDR are individually evaluated for an ALLL. Allowances for individually evaluated loans that are collateral-dependent are typically measured based on the fair value of the underlying collateral, less expected costs to sell where applicable. Individually evaluated loans that are not collateral-dependent are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate and a modeled expected credit loss amount. The Bancorp

59 Fifth Third Bancorp evaluates the collectability of both principal and interest when assessing the need for a loss accrual. Specific allowances on individually evaluated consumer and residential mortgage loans are reviewed quarterly and adjusted as necessary based on changing borrower and/or collateral conditions and actual collection and charge-off experience.

Expected credit losses are estimated on a collective basis for loans and leases that are not individually evaluated. These include commercial loans and leases that do not meet the criteria for individual evaluation as well as homogeneous loans in the residential mortgage and consumer portfolio segments. For collectively evaluated loans and leases, the Bancorp uses models to forecast expected credit losses based on the probability of a loan or lease defaulting, the expected balance at the estimated date of default and the expected loss percentage given a default. The estimate of the expected balance at the time of default considers prepayments and, for loans with available credit, expected utilization rates. The Bancorp’s expected credit loss models were developed based on historical credit loss experience and observations of migration patterns for various credit risk characteristics (such as internal credit risk grades, external credit ratings or scores, delinquency status, loan-to-value trends, etc.) over time, with those observations evaluated in the context of concurrent macroeconomic conditions. The Bancorp developed its models from historical observations capturing a full economic cycle when possible.

Overall, the collective evaluation process requires significant management judgment when determining the estimation methodology and inputs into the models, as well as in evaluating the reasonableness of the modeled results and the appropriateness of qualitative adjustments. The Bancorp’s forecasts of market and economic conditions and the internal risk grades assigned to loans and leases in the commercial portfolio segment are examples of inputs to the expected credit loss models that require significant management judgment. These inputs have the potential to drive significant variability in the resulting ALLL.
