1Q 2021 Preliminary Results 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-partydata available atthe 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, 2020, 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 consultfurther disclosures (including disclosures ofa forward-lookingnature) thatwe maymake 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 definedbylaw. 2

1Q 2021 Preliminary Results Supplemental Notes on Non-GAAP Financial Measures The following are non-GAAP financial measures which Ally believes are important to the reader of the Consolidated Financial Stat ements, 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 orig inal 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. For calculation methodology, refer to the 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 peri od 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 (change in fair value of equity securities impacts the Insurance and Corporate Finance segments), 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 or businesses. 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 page 33 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 29 calculation methodology and details. 3) 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 30 for more details. 4) 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. Core OID for all periods shown is applied to the pre-tax income of the Corporate and Other segment. See page 34 calculation methodology and details. 5) 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 34 for calculation methodology and details 6) Accelerated issuance expense (Accelerated OID) is the recognition of issuance expenses related to calls of redeemable debt. 7) 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 informati on. 28

Management believes Adjusted EPS can help the reader better understand the operating performance of the core businesses and their ability to generate earnings. In the numerator of Adjusted EPS, GAAP net income attributable to common shareholders is adjusted for the following items: (1) excludes discontinued operations, net of tax, as Ally is primarily a domestic company and sales of international businesses and other discontinued operations in the past have significantly impacted GAAP EPS, (2) adds back the tax-effected non-cash Core OID, (3) adjusts for tax-effected repositioning and other which are primarily related to the extinguishment of high cost legacy debt, strategic activities and significant other one-time items, (4) excludes equity fair value adjustments (net of tax) 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, (5) excludes significant di screte tax items that do not relate to the operating performance of the core businesses, and adjusts for preferred stock capital actions (e.g., Series A and Series G) that have been taken by the company to normalize its capital structure, as applicable for respective periods. 29

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. Adjusted TBVPS generally adjusts common equity for: (1) goodwill and identifiable intangibles, net of DTLs, (2) tax-effected Core OID balance to reduce tangible common equity in the event the corresponding discounted bonds are redeemed/tendered, and (3) Series G discount which reduces tangible common equity as the company has normalized its capital structure, as applicable for respective periods. Note: In December 2017, tax-effected Core OID balance was adjusted from a statutory U.S. Federal tax rate of 35% to 21% (“rate”) as a result of changes to U.S. tax law. The adjustment conservatively increased the tax-effected Core OID balance and consequently reduced Adjusted TBVPS as any acceleration of the non-cash charge in future periods would flow through the financial statements at a 21% rate versus a previously modeled 35% rate.

Upon implementation of CECL Ally recognized a reduction to our opening retained earnings balance of approximately $1.0 billion, net of income tax, which reflects a pre-tax increase to the allowance for loan losses of approximately $1.3 billion. This increase is almost exclusively driven by our consumer automotive loan portfolio. 30

For purposes of this calculation, tangible common equity is adjusted for Core OID balance and net DTA. Ally’s Core net income attributable to common shareholders for purposes of calculating Core ROTCE is bas ed on the actual effective tax rate for the period adjusted for significant discrete tax items including tax reserve releases, which aligns with the methodology used in calculating adjusted earnings per share. (1) In the numerator of Core ROTCE, GAAP net income attributable to common shareholders is adjusted for discontinued operations n et of tax, tax-effected Core OID, tax- effected repositioning and other which are primarily related to the extinguishment of high cost legacy debt, strategic activities and significant other one-time items, fair value adjustments (net of tax) 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 componentof equity, significant discrete tax items, and preferred stock capital actions, as applicable for respective periods. (2) In the denominator, GAAP shareholder’s equity is adjusted for goodwill and identifiable intangibles net of DTL, Core OID balance, and net DTA. 31

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 is sued 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 fi ve-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. 6) Change in fair value of equity securities impacts the Insurance and Corporate Finance segments.
