Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of American Express Company and its subsidiaries (the “Company”) as of December 31, 2024 and 2023, and the related consolidated statements of income, of comprehensive income, of shareholders’ equity and of cash flows for each of the three years in the period ended December 31, 2024, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Reserves for Credit Losses on Card Member Loans

As described in Note 3 to the consolidated financial statements, reserves for credit losses on Card Member loans represent management’s estimate of the expected credit losses in the Company’s outstanding portfolio of Card Member loans as of the balance sheet date. The reserves for credit losses on Card Member loans was $5.7 billion as of December 31, 2024. Management estimates lifetime expected credit losses by incorporating historical loss experience, as well as current and future economic conditions over a reasonable and supportable period (R&S Period) beyond the balance sheet date. As disclosed by management, in estimating expected credit losses, management uses a combination of statistically-based models that entail a significant amount of judgment. The primary areas of judgment used in measuring the quantitative components of the Company’s reserves relate to the determination of the appropriate R&S Period, the modeling of the probability of and exposure at default, and the methodology to incorporate current and future economic conditions. Management uses these models and assumptions, combined with historical loss experience, to determine the reserve rates that are applied to the outstanding loan balances to produce its reserves for expected credit losses. Within the R&S Period, the Company’s models use past loss experience and current and future economic conditions to estimate the probability of default, exposure at default and expected recoveries to estimate net losses at default. Beyond the R&S Period, expected credit losses are estimated by immediately reverting to long-term average loss rates. Management also estimates the likelihood and magnitude of recovery of previously written off loans considering how long ago the loan was written off and future economic conditions. Additionally, management evaluates whether to include qualitative reserves to cover losses that are expected but may not be adequately represented in the quantitative methods or the economic assumptions. The qualitative reserves address possible limitations within the models or factors not included within the models, such as external conditions, emerging portfolio trends, the nature and size of the portfolio, portfolio concentrations, the volume and severity of past due accounts, or management risk actions.

The principal considerations for our determination that performing procedures relating to the reserves for credit losses on Card Member loans is a critical audit matter are (i) the estimate of the reserves for credit losses on Card Member loans involved significant judgment by management, which in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence relating to the models, significant inputs, qualitative reserves, and significant assumptions, including the R&S Period and the loss rates used to estimate expected credit losses beyond the R&S Period and (ii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the reserves for credit losses on Card Member loans. These procedures also included, among others, testing management’s process for estimating the reserves for credit losses on Card Member loans through (i) evaluating the appropriateness of management’s methodology, (ii) testing the completeness and accuracy of significant inputs and (iii) evaluating the reasonableness of certain qualitative reserves and significant assumptions used to estimate the reserves. Professionals with specialized skill and knowledge were used to assist in evaluating the appropriateness of management’s methodology and the reasonableness of certain qualitative reserves and certain significant assumptions, including the R&S Period and the loss rates used to estimate expected credit losses beyond the R&S Period.

Membership Rewards Liability

As described in Note 9 to the consolidated financial statements, the Membership Rewards liability represents management’s estimate of the cost of Membership Rewards points earned that are expected to be redeemed in the future. The Membership Rewards liability was $14.8 billion as of December 31, 2024. The weighted average cost (WAC) per point and the Ultimate Redemption Rate (URR) are key assumptions used to estimate the liability. As disclosed by management, the URR assumption is used by management to estimate the number of points earned that will ultimately be redeemed in future periods. Management uses statistical and actuarial models to estimate the URR based on redemption trends, card product type, enrollment tenure, card spend levels and credit attributes. The WAC per point assumption is derived from 12 months of redemptions and is adjusted as appropriate for certain changes in redemption costs that are not representative of future cost expectations and expected developments in redemption patterns.

The principal considerations for our determination that performing procedures relating to the Membership Rewards liability is a critical audit matter are (i) the estimate of the URR involved significant judgment by management, which in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating the audit evidence relating to the models, significant inputs and assumptions used by management and (ii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the estimate of the Membership Rewards liability, including the URR and WAC assumptions. These procedures also included, among others, (i) testing the completeness and accuracy of significant inputs to the statistical and actuarial models used to estimate the URR assumption, including redemption trends, card product type, enrollment tenure, and card spend levels, (ii) the involvement of professionals with specialized skill and knowledge to assist in developing an independent estimate of the URR assumption and comparing the independent estimate to management’s assumption to evaluate its reasonableness and (iii) comparing our independently calculated Membership Rewards liability to management’s estimate.
