Appendix I

(1) Ratios as of June 30, 2025 are preliminary. Citigroup’s allocated average tangible common equity (TCE) and return on average tangible common equity (RoTCE) are non-GAAP financial measures. RoTCE represents annualized net income available to common shareholders as a percentage of average TCE. For the components of these calculations, see Appendix A. For a reconciliation of common equity to TCE, see Appendix F. For a reconciliation of the summation of the segments’ and components’ average allocated TCE to Citigroup’s total average stockholder’s equity, see Appendix H.

As used herein, 2026 RoTCE is a forward-looking non-GAAP financial measure. From time to time, management may discuss forward-looking non-GAAP financial measures, such as forward-looking estimates or targets for revenue, expenses and RoTCE. Citi is unable to provide a reconciliation of forward-looking non-GAAP financial measures to their most directly comparable GAAP financial measures because Citi is unable to provide, without unreasonable effort, a meaningful or accurate calculation or estimation of amounts that would be necessary for the reconciliation due to the complexity and inherent difficulty in forecasting and quantifying future amounts or when they may occur. Such unavailable information could be significant for future results.

(2)Ratios as of June 30, 2025 are preliminary. Commencing January 1, 2025, the capital effects resulting from adoption of the Current Expected Credit Losses (CECL) methodology have been fully reflected in Citi's regulatory capital. For additional information, see “Capital Resources—Regulatory Capital Treatment—Modified Transition of the Current Expected Credit Losses Methodology” in Citigroup’s 2024 Annual Report on Form 10-K. For the composition of Citigroup’s CET1 Capital and ratio, see Appendix D. For the composition of Citigroup’s SLR, see Appendix E.

(3)Citigroup’s payout ratio is the sum of common dividends and common share repurchases divided by net income available to common shareholders.

(4)Citigroup’s tangible book value per share is a non-GAAP financial measure. For a reconciliation of common equity to tangible common equity and resulting calculation of tangible book value per share, see Appendix F.

(5)Citigroup’s revenues excluding divestiture-related impacts are non-GAAP financial measures. For a reconciliation to reported results, see Appendices B and C. The reconciling items’ impact on revenue is reflected in non-interest revenue.

(6) Citigroup’s expenses excluding divestiture-related impacts are non-GAAP financial measures. For a reconciliation to reported results, see Appendices B and C. Included in Citi's reported expenses was an immaterial decrease in expenses of $(20) million in the second quarter 2025 related to a lower incremental FDIC special assessment, compared to $34 million in the second quarter 2024.

(7)Prime balances are defined as client’s billable balances where Citigroup provides cash or synthetic prime brokerage services.

(8)Credit derivatives are used to economically hedge a portion of the Corporate Lending portfolio that includes both accrual loans and loans at fair value. Gain/(loss) on loan hedges includes the mark-to-market on the credit derivatives and the mark-to-market on the loans in the portfolio that are at fair value. The fixed premium costs of these hedges are netted against the Corporate Lending revenues to reflect the cost of credit protection. Citigroup’s results of operations excluding the impact of gain / (loss) on loan hedges are non-GAAP financial measures. For a reconciliation to reported results, see Appendix G.

(9)Reflects the impact of the net deposit balance transfers from USPB to Citigold inWealth of approximately $17 billion over the last 5 quarters, including approximately $3 billion during the second quarter 2025. These amounts represent the balances at the time client relationships are transferred.

(10) All Other (managed basis) reflects results on a managed basis, which excludes divestiture-related impacts, for all periods, related to Citigroup’s divestitures of its Asia consumer banking businesses and the planned divestiture of Banamex within Legacy Franchises. Certain of the results of operations ofAll Other (managed basis) and Legacy Franchises (managed basis) that exclude divestiture-related impacts are non-GAAP financial measures. For additional information and a reconciliation of these results, see Appendix C.
