All references to net earnings and net income are intended to have the same meaning. All comparisons are for the third quarter of 2023 compared to the third quarter of 2022, unless otherwise noted. This presentation contains certain forward-looking statements as defined in Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, which are subject to the "safe harbor" created by those sections. Forward-looking statements may be identified by words such as "expects," "intends," "anticipates," "plans," "believes," "seeks," "targets," "outlook," "estimates," "will," "should," "may" or words of similar meaning, but these words are not the exclusive means of identifying forward-looking statements. Forward- looking statements are based on management's current expectations and assumptions, and are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. As a result, actual results could differ materially from those indicated in these forward-looking statements. Factors that could cause actual results to differ materially include global political, economic, business, competitive, market, regulatory and other factors and risks, such as: the impact of macroeconomic conditions and whether industry trends we have identified develop as anticipated, including the future impacts of the novel coronavirus disease (“COVID-19”) outbreak and measures taken in response thereto for which future developments are highly uncertain and difficult to predict; retaining existing partners and attracting new partners, concentration of our revenue in a small number of partners, and promotion and support of our products by our partners; cyber-attacks or other security breaches; disruptions in the operations of our and our outsourced partners' computer systems and data centers; the financial performance of our partners; the sufficiency of our allowance for credit losses and the accuracy of the assumptions or estimates used in preparing our financial statements, including those related to the CECL accounting guidance; higher borrowing costs and adverse financial market conditions impacting our funding and liquidity, and any reduction in our credit ratings; our ability to grow our deposits in the future; damage to our reputation; our ability to securitize our loan receivables, occurrence of an early amortization of our securitization facilities, loss of the right to service or sub-service our securitized loan receivables, and lower payment rates on our securitized loan receivables; changes in market interest rates and the impact of any margin compression; effectiveness of our risk management processes and procedures, reliance on models which may be inaccurate or misinterpreted, our ability to manage our credit risk; our ability to offset increases in our costs in retailer share arrangements; competition in the consumer finance industry; our concentration in the U.S. consumer credit market; our ability to successfully develop and commercialize new or enhanced products and services; our ability to realize the value of acquisitions and strategic investments; reductions in interchange fees; fraudulent activity; failure of third-parties to provide various services that are important to our operations; international risks and compliance and regulatory risks and costs associated with international operations; alleged infringement of intellectual property rights of others and our ability to protect our intellectual property; litigation and regulatory actions; our ability to attract, retain and motivate key officers and employees; tax legislation initiatives or challenges to our tax positions and/or interpretations, and state sales tax rules and regulations; regulation, supervision, examination and enforcement of our business by governmental authorities, the impact of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) and other legislative and regulatory developments and the impact of the Consumer Financial Protection Bureau’s (the “CFPB”) regulation of our business; impact of capital adequacy rules and liquidity requirements; restrictions that limit our ability to pay dividends and repurchase our common stock, and restrictions that limit the Bank’s ability to pay dividends to us; regulations relating to privacy, information security and data protection; use of third-party vendors and ongoing third-party business relationships; and failure to comply with anti-money laundering and anti-terrorism financing laws. For the reasons described above, we caution you against relying on any forward-looking statements, which should also be read in conjunction with the other cautionary statements that are included elsewhere in this presentation and in our public filings, including under the heading “Risk Factors Relating to Our Business” and “Risk Factors Relating to Regulation” in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2022, as filed on February 9, 2023. You should not consider any list of such factors to be an exhaustive statement of all the risks, uncertainties, or potentially inaccurate assumptions that could cause our current expectations or beliefs to change. Further, any forward-looking statement speaks only as of the date on which it is made, and we undertake no obligation to update or revise any forward-looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events, except as otherwise may be required by law.

11 2023 Outlook Key Driver Original Current Trends / Update Loan receivables growth 8 – 10% ~11% • 3Q driven by payment rate moderation and purchase volume growth • Expect purchase volume growth rate to slow and payment rate moderation to continue, but remain above pre-pandemic levels through year-end Net interest margin 15.00 – 15.25% ~15.15% • 3Q NIM influenced by: – Higher interest and fees on loans growth, driven by higher average receivables growth and payment rate moderation – Better than expected deposit betas • Expect 4Q NIM to be driven by potential variables: – Higher average liquidity to pre-fund seasonal growth – Higher deposit betas driven by competition and benchmark rate increases – Interest and fees on loans growth, partly offset by rising reversals Net charge-offs 4.75 – 5.00% ~4.85% • Credit performance remains in line with expectations – Delinquencies expected to follow seasonal trends moving forward – NCO dollars to continue rising through year; NCO rate not expected to reach pre-pandemic levels on an annual basis until 2024 RSA / Average loan receivables 4.00 – 4.25% ~3.95% • Improvement in RSA driven by continued credit normalization, lower net interest margin, and the mix of loan receivables growth, partially offset by higher purchase volume Operating expenses ~$1,125MM per qtr ~$1,150MM per qtr • Expense increase driven by growth, technology investments and operational losses • Managing expenses to deliver positive operating leverage (expense growth lower than NII growth) for the full year (comments and trends in comparison to 2022, except where noted) Full Year 2023

Accounts represent average active accounts in millions, which are credit card or installment loan accounts on which there has been a purchase, payment or outstanding balance in the current month. Purchase volume $ in billions and Interest and fees on loans $ in millions. Net Interest Income: a. Payment rate is calculated as customer payments divided by beginning of period loan receivables. b. Historical payment rate excludes portfolios sold in 2019 and 2022. Asset Quality: a. Allowance for credit losses reflects the adoption of ASU 2022-22, “Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures” on January 1, 2023, which included a $294 million reduction to the allowance for credit losses upon adoption. Other Expense a. Other expense divided by sum of Net interest income plus Other income less Retailer share arrangements (RSA). Funding, Capital and Liquidity a. Does not include unencumbered assets in the Bank that could be pledged. b. Capital ratios reflect the phase-in of an estimate of CECL’s effect on regulatory capital over a three-year transitional period beginning in the first quarter of 2022 through 2024. CET1, Tier 1, and Total Capital Ratio are presented on a Transition basis and capital ratios for 2023 and 2022 reflect 50% and 25%, respectively, of the phase-in of CECL effects.
