Forward-Looking Statements and Additional Information This presentation and related communications should be read in conjunction with the financial statements, notes, and other information contained in our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K. This information is preliminary and based on company and third-party data available at the time of the presentation or related communication. This presentation and related communications contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements can be identified by the fact that they do not relate strictly to historical or current facts—such as statements about future effects of COVID-19 and our ability to navigate them, the outlook for financial and operating metrics and performance, and future capital allocation and actions. Forward-looking statements often use words such as “believe,” “expect,” “anticipate,” “intend,” “pursue,” “seek,” “continue,” “estimate,” “project,” “outlook,” “forecast,” “potential,” “target,” “objective,” “trend,” “plan,” “goal,” “initiative,” “priorities,” or other words of comparable meaning or future-tense or conditional verbs such as “may,” “will,” “should,” “would,” or “could.” Forward-looking statements convey our expectations, intentions, or forecasts about future events, circumstances, or results. All forward-looking statements, by their nature, are subject to assumptions, risks, and uncertainties, which may change over time and many of which are beyond our control. You should not rely on any forward-looking statement as a prediction or guarantee about the future. Actual future objectives, strategies, plans, prospects, performance, conditions, or results may differ materially from those set forth in any forward-looking statement. Some of the factors that may cause actual results or other future events or circumstances to differ from those in forward-looking statements are described in our Annual Report on Form 10-K for the year ended December 31, 2019, our subsequent Quarterly Reports on Form 10-Q or Current Reports on Form 8-K, or other applicable documents that are filed or furnished with the U.S. Securities and Exchange Commission (collectively, our “SEC filings”). Any forward-looking statement made by us or on our behalf speaks only as of the date that it was made. We do not undertake to update any forward-looking statement to reflect the impact of events, circumstances, or results that arise after the date that the statement was made, except as required by applicable securities laws. You, however, should consult further disclosures (including disclosures of a forward-looking nature) that we may make in any subsequent SEC filings. This presentation and related communications contain specifically identified non-GAAP financial measures, which supplement the results that are reported according to U.S. generally accepted accounting principles (“GAAP”). These non-GAAP financial measures may be useful to investors but should not be viewed in isolation from, or as a substitute for, GAAP results. Differences between non- GAAP financial measures and comparable GAAP financial measures are reconciled in the presentation. Unless the context otherwise requires, the following definitions apply. The term “loans” means the following consumer and commercial products associated with our direct and indirect financing activities: loans, retail installment sales contracts, lines of credit, and other financing products excluding operating leases. The term “operating leases” means consumer- and commercial- vehicle lease agreements where Ally is the lessor and the lessee is generally not obligated to acquire ownership of the vehicle at lease-end or compensate Ally for the vehicle’s residual value. The terms “lend,” “finance,” and “originate” mean our direct extension or origination of loans, our purchase or acquisition of loans, or our purchase of operating leases, as applicable. The term “consumer” means all consumer products associated with our loan and operating-lease activities and all commercial retail installment sales contracts. The term “commercial” means all commercial products associated with our loan activities, other than commercial retail installment sales contracts. The term “partnerships” means business arrangements rather than partnerships as defined by law. 4Q 2020 Preliminary Results 2Forward-Looking Statements and Additional Information This presentation and related communications should be read in conjunction with the financial statements, notes, and other information contained in our Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K.

These measures are used by management and we believe are useful to investors in assessing thecompany’s operating performance and capital. Refer to the Definitions of Non-GAAP Financial Measures and Other Key Terms, and Reconciliation to GAAP later in this document. (2) Core net income (loss) attributable to common shareholders is a non-GAAP financial measure that serves as the numerator in the calculations of Adjusted EPS and Core ROTCE and that, like those measures, is believed by management to help the reader better understand the operating performance of the core businesses and their ability to generate earnings. See page 30 and 32 for calculation methodology and details. (3) Adjusted earnings per share (Adjusted EPS) is a non-GAAP financial measure that adjusts GAAP EPS for revenue and expense items that are typically strategic in nature or that management otherwise does not view as reflecting the operating performance of the company. Management believes Adjusted EPS can help the reader better understand the operating performance of the core businesses and their ability to generate earnings. See page 32 for calculation methodology and details. (4) Core return on tangible common equity (Core ROTCE) is a non-GAAP financial measure that management believes is helpful for readers to better understand the ongoing ability of the company to generate returns on its equity base that supports core operations. For purposes of this calculation, tangible common equity is adjusted for Core OID balance and the net deferred tax asset. See page 36 for calculation methodology and details. (5) Adjusted tangible book value per share (Adjusted TBVPS) is a non-GAAP financial measure that reflects the book value of equity attributable to shareholders even if tax-effected Core OID balance were accelerated immediately through the financial statements. As a result, management believes Adjusted TBVPS provides the reader with an assessment of value that is more conservative than GAAP common shareholder’s equity per share. See page 34 for calculation methodology and details. (6) Adjusted efficiency ratio is a non-GAAP financial measure that management believes is helpful to readers in comparing the efficiency of its core banking and lending businesses with those of its peers. Adjusted efficiency ratio generally adjusts for Insurance segment revenue and expense, rep and warrant expense, Core OID, and repositioning and other. See page 38 for calculation methodology and details. (7) Adjusted total net revenue is a non-GAAP financial measure that adjusts GAAP total net revenue for Core OID and for change in the fair value of equity securities due to the implementation of ASU 2016-01 which requires change in the fair value of equity securities to be recognized in current period net income as compared to periods prior to 1/1/18 in which such adjustments were recognized through other comprehensive income, a component of equity. See page 40 for calculation methodology and details. 4Q 2020 Preliminary Results 3GAAP and Core Results: Annual ($ millions except per share data) 2020 2019 2018 2017 2016 2015 2014 GAAP net income (loss) attributable to common shareholders ( NIAC ) $ 1,085 $ 1,715 $ 1,263 $ 929 $ 1,037 $ (1,282) $ 882 (1)(2) Core net income attributable to common shareholders $ 1,141 $ 1,472 $ 1,427 $ 1,091 $ 1,043 $ 967 $ 812 GAAP earnings per common share ( EPS ) (diluted, NIAC) $ 2.88 $ 4.34 $ 2.95 $ 2.04 $ 2.15 $ (2.66) $ 1.83 (1)(3) Adjusted EPS $ 3.03 $ 3.72 $ 3.34 $ 2.39 $ 2.16 $ 2.00 $ 1.68 Return (net income) on GAAP shareholder's equity 7.7% 12.4% 9.4% 6.9% 8.0% 8.9% 7.8% (1)(4) Core ROTCE 9.1% 12.0% 12.3% 9.8% 10.0% 9.4% 7.9% GAAP common shareholder's equity per share $ 39.2 $ 38.5 $ 32.8 $ 30.9 $ 28.5 $ 26.4 $ 29.5 (1)(5) Adjusted tangible book value per share $ 36.1 $ 35.1 $ 29.9 $ 28.1 $ 26.2 $ 24.6 $ 22.7 Efficiency Ratio 57.3% 53.6% 56.2% 53.9% 54.1% 56.8% 63.4% (1)(6) Adjusted Efficiency Ratio 50.3% 47.4% 47.6% 45.8% 45.4% 45.3% 50.8% GAAP total net revenue $ 6,686 $ 6,394 $ 5,804 $ 5,765 $ 5,437 $ 4,861 $ 4,651 (1)(7) Adjusted total net revenue $ 6,692 $ 6,334 $ 6,011 $ 5,836 $ 5,498 $ 5,262 $ 4,985 Effective Tax Rate 23.2% 12.5% 22.1% 38.6% 29.7% 35.6% 25.7% (1) The following are non-GAAP financial measures which Ally believes are important to the reader of the Consolidated Financial Statements, but which are supplemental to and not a substitute for GAAP measures: Adjusted earnings per share (Adjusted EPS), Core pre-tax income (loss), Core net income (loss) attributable to common shareholders, Core return on tangible common equity (Core ROTCE), Adjusted efficiency ratio, Adjusted total net revenue, Net financing revenue (excluding Core OID), Adjusted other revenue, Core original issue discount (Core OID) amortization expense, Core outstanding original issue discount balance (Core OID balance), and Adjusted tangible book value per share (Adjusted TBVPS).

Supplemental Notes on Non-GAAP and Other Financial Measures The following are non-GAAP financial measures which Ally believes are important to the reader of the Consolidated Financial Statements, but which are supplemental to, and not a substitute for, GAAP measures: Adjusted Earnings per Share (Adjusted EPS), Core pre-tax income, Core net income attributable to common shareholders, Core return on tangible common equity (Core ROTCE), Adjusted efficiency ratio, Adjusted total net revenue, Adjusted other revenue, Adjusted noninterest expense, Core original issue discount (Core OID) amortization expense and Core outstanding original issue discount balance (Core OID balance), Net financing revenue (excluding Core OID), and Adjusted tangible book value per share (Adjusted TBVPS). These measures are used by management and we believe are useful to investors in assessing the company’s operating performance and capital. Refer to the Definitions of Non-GAAP Financial Measures and Other Key Terms, and Reconciliation to GAAP later in this document. 1) Core pre-tax income is a non-GAAP financial measure that adjusts pre-tax income from continuing operations by excluding (1) Core OID, and (2) equity fair value adjustments related to ASU 2016-01 which requires change in the fair value of equity securities to be recognized in current period net income as compared to periods prior to 1/1/18 in which such adjustments were recognized through other comprehensive income, a component of equity, and (3) Repositioning and other which are primarily related to the extinguishment of high cost legacy debt, strategic activities and significant other one-time items, as applicable for respective periods. Management believes core pre-tax income can help the reader better understand the operating performance of the core businesses and their ability to generate earnings. See pages 40-42 for calculation methodology and details. 2) Core net income attributable to common shareholders is a non-GAAP financial measure that serves as the numerator in the calculations of Adjusted EPS and Core ROTCE and that, like those measures, is believed by management to help the reader better understand the operating performance of the core businesses and their ability to generate earnings. Core net income attributable to common shareholders adjusts GAAP net income attributable to common shareholders for discontinued operations net of tax, tax-effected Core OID expense, tax-effected repositioning and other primarily related to the extinguishment of high-cost legacy debt and strategic activities and significant other, preferred stock capital actions, significant discrete tax items and tax-effected changes in equity investments measured at fair value, as applicable for respective periods. See page 32 and 33 for calculation methodology and details. 3) Core original issue discount (Core OID) amortization expense is a non-GAAP financial measure for OID and is believed by management to help the reader better understand the activity removed from: Core pre-tax income (loss), Core net income (loss) attributable to common shareholders, Adjusted EPS, Core ROTCE, Adjusted efficiency ratio, Adjusted total net revenue, and Net financing revenue (excluding Core OID). Core OID is primarily related to bond exchange OID which excludes international operations and future issuances. See page 43 and 44 for calculation methodology and details. 4) Core outstanding original issue discount balance (Core OID balance) is a non-GAAP financial measure for outstanding OID and is believed by management to help the reader better understand the balance removed from Core ROTCE and Adjusted TBVPS. Core OID balance is primarily related to bond exchange OID which excludes international operations and future issuances. See page 43 for calculation methodology and details 5) Accelerated issuance expense (Accelerated OID) is the recognition of issuance expenses related to calls of redeemable debt. 6) Interest rate risk modeling – We prepare our forward-looking baseline forecasts of net financing revenue taking into consideration anticipated future business growth, asset/liability positioning, and interest rates based on the implied forward curve. The analysis is highly dependent upon a variety of assumptions including the repricing characteristics of retail deposits with both contractual and non-contractual maturities. We continually monitor industry and competitive repricing activity along with other market factors when contemplating deposit pricing actions. Please see the 10-K for more details. 7) Net charge-off ratios are calculated as annualized net charge-offs divided by average outstanding finance receivables and loans excluding loans measured at fair value and loans held-for-sale. 8) Tangible Common Equity is a non-GAAP financial measure that is defined as common stockholders’ equity less goodwill and identifiable intangible assets, net of deferred tax liabilities. Ally considers various measures when evaluating capital adequacy, including tangible common equity. Ally believes that tangible common equity is important because we believe readers may assess our capital adequacy using this measure. Additionally, presentation of this measure allows readers to compare certain aspects of our capital adequacy on the same basis to other companies in the industry. For purposes of calculating Core return on tangible common equity (Core ROTCE), tangible common equity is further adjusted for Core OID balance and net deferred tax asset. See page 33 and 34 for more details. 9) U.S. consumer auto originations ▪ New Retail – standard and subvented rate new vehicle loans ▪ Lease – new vehicle lease originations ▪ Used – used vehicle loans ▪ Growth – total originations from non-GM/Chrysler dealers and direct-to-consumer loans ▪ Nonprime – originations with a FICO® score of less than 620 10) Customer retention rate is the annualized 3-month rolling average of 1 minus the monthly attrition rate; excludes escheatment. 4Q 2020 Preliminary Results 30Supplemental Notes on Non-GAAP and Other Financial Measures The following are non-GAAP financial measures which Ally believes are important to the reader of the Consolidated Financial Statements, but which are supplemental to, and not a substitute for, GAAP measures: Adjusted Earnings per Share (Adjusted EPS), Core pre-tax income, Core net income attributable to common shareholders, Core return on tangible common equity (Core ROTCE), Adjusted efficiency ratio, Adjusted total net revenue, Adjusted other revenue, Adjusted noninterest expense, Core original issue discount (Core OID) amortization expense and Core outstanding original issue discount balance (Core OID balance), Net financing revenue (excluding Core OID), and Adjusted tangible book value per share (Adjusted TBVPS).

Supplemental Notes on Non-GAAP and Other Financial Measures 11) Estimated Retail Auto Originated Yield is a forward-looking non-GAAP financial measure determined by calculating the estimated average annualized yield for loans originated during the period. At this time there currently is no comparable GAAP financial measure for Estimated Retail Auto Originated Yield and therefore this forecasted estimate of yield at the time of origination cannot be quantitatively reconciled to comparable GAAP information. 12) Estimated impact of CECL on regulatory capital per final rule issued by U.S. banking agencies - In December 2018, the FRB and other U.S. banking agencies approved a final rule to address the impact of CECL on regulatory capital by allowing BHCs and banks, including Ally, the option to phase in the day-one impact of CECL over a three-year period. In March 2020, the FRB and other U.S. banking agencies issued an interim final rule that became effective on March 31, 2020 and provided an alternative option for banks to temporarily delay the impacts of CECL, relative to the incurred loss methodology for estimating the allowance for loan losses, on regulatory capital. A final rule that was largely unchanged from the March 2020 interim final rule was issued by the FRB and other U.S. banking agencies in August 2020, and became effective in September 2020. For regulatory capital purposes, these rules permitted us to delay recognizing the estimated impact of CECL on regulatory capital until after a two-year deferral period, which for us extends through December 31, 2021. Beginning on January 1, 2022, we will be required to phase in 25% of the previously deferred estimated capital impact of CECL, with an additional 25% to be phased in at the beginning of each subsequent year until fully phased in by the first quarter of 2025. Under these rules, firms that adopt CECL and elect the five-year transition will calculate the estimated impact of CECL on regulatory capital as the day-one impact of adoption plus 25% of the subsequent change in allowance during the two-year deferral period, which according to the final rule approximates the impact of CECL relative to an incurred loss model. We adopted this transition option during the first quarter of 2020, and plan to phase in the regulatory capital impacts of CECL based on this five-year transition period. 4Q 2020 Preliminary Results 31Supplemental Notes on Non-GAAP and Other Financial Measures 11) Estimated Retail Auto Originated Yield is a forward-looking non-GAAP financial measure determined by calculating the estimated average annualized yield for loans originated during the period. At this time there currently is no comparable GAAP financial measure for Estimated Retail Auto Originated Yield and therefore this forecasted estimate of yield at the time of origination cannot be quantitatively reconciled to comparable GAAP information. 12) Estimated impact of CECL on regulatory capital per final rule issued by U.S. banking agencies - In December 2018, the FRB and other U.S. banking agencies approved a final rule to address the impact of CECL on regulatory capital by allowing BHCs and banks, including Ally, the option to phase in the day-one impact of CECL over a three-year period. In March 2020, the FRB and other U.S. banking agencies issued an interim final rule that became effective on March 31, 2020 and provided an alternative option for banks to temporarily delay the impacts of CECL, relative to the incurred loss methodology for estimating the allowance for loan losses, on regulatory capital. A final rule that was largely unchanged from the March 2020 interim final rule was issued by the FRB and other U.S. banking agencies in August 2020, and became effective in September 2020. For regulatory capital purposes, these rules permitted us to delay recognizing the estimated impact of CECL on regulatory capital until after a two-year deferral period, which for us extends through December 31, 2021. Beginning on January 1, 2022, we will be required to phase in 25% of the previously deferred estimated capital impact of CECL, with an additional 25% to be phased in at the beginning of each subsequent year until fully phased in by the first quarter of 2025. Under these rules, firms that adopt CECL and elect the five-year transition will calculate the estimated impact of CECL on regulatory capital as the day-one impact of adoption plus 25% of the subsequent change in allowance during the two-year deferral period, which according to the final rule approximates the impact of CECL relative to an incurred loss model. We adopted this transition option during the first quarter of 2020, and plan to phase in the regulatory capital impacts of CECL based on this five-year transition period. 4Q 2020 Preliminary Results 31
