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 the outlook for various financial and operating metrics and statements about 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, 2018, 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.

GAAP and Core Results 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, fully phased-in Common Equity Tier 1 (CET1) capital, 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). 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. 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. See pages 23 and 24 for calculation methodology and details. 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 24 for calculation methodology and details. 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 26 for calculation methodology and details. 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 25 for calculation methodology and details. 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 and Core OID. See page 27 for calculation methodology and details. 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 30 for calculation methodology and details.

Notes on Non-GAAP and Other Financial Measures Supplemental Accelerated issuance expense (Accelerated OID) is the recognition of issuance expenses related to calls of redeemable debt. 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 items primarily related to the extinguishment of high-cost legacy debt and strategic activities, certain discrete tax items and preferred stock capital actions and tax-effected changes in equity investments measured at fair value. See page 24 for calculation methodology and details. Core original issue discount (Core OID) amortization expense is a non-GAAP financial measure for OID, primarily related to bond exchange OID which excludes international operations and future issuances. See page 30 for calculation methodology and details. Core outstanding original issue discount balance (Core OID balance) is a non-GAAP financial measure for outstanding OID, primarily related to bond exchange OID which excludes international operations and future issuances. See page 30 for calculation methodology and details. 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) repositioning items primarily related to the extinguishment of high-cost legacy debt and strategic activities and (3) 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. 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 29 for calculation methodology and details. 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. Based on current market conditions, actual beta on our total retail deposits portfolio has been approximately 44% since the third quarter of 2015. We continually monitor industry and competitive repricing activity along with other market factors when contemplating deposit pricing actions. Please see the 10-Q for more details. 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. 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 25 for more details. 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 Customer retention rate is the annualized 3-month rolling average of 1 minus the monthly attrition rate. Growth channel for Insurance includes all non-GM volume. 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, fully phased-in Common Equity Tier 1 (CET1) capital, Adjusted Total Net Revenue, Adjusted Other Revenue, 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.

GAAP to Core Results – Adjusted Earnings per Share Supplemental 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. 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) adds back tax-effected repositioning items primarily related to the extinguishment of high-cost legacy debt and strategic activities, (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 certain discrete tax items that do not relate to the operating performance of the core businesses, and (6) 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.

GAAP to Core Results – Adjusted TBVPS Supplemental 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 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. 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. 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.

GAAP to Core Results – Core ROTCE Supplemental 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 net DTA. Ally’s Core net income attributable to common shareholders for purposes of calculating Core ROTCE is based on the actual effective tax rate for the period adjusted for any discrete tax items including tax reserve releases, which aligns with the methodology used in calculating adjusted earnings per share. In the numerator of Core ROTCE, GAAP net income attributable to common shareholders is adjusted for discontinued operations net of tax, tax-effected Core OID, 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, certain discrete tax items and preferred stock capital actions. In the denominator, GAAP shareholder’s equity is adjusted for preferred equity and goodwill and identifiable intangibles net of DTL, Core OID balance, and net DTA.

GAAP to Core Results – Adjusted Efficiency Ratio Supplemental 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. In the numerator of Adjusted efficiency ratio, total noninterest expense is adjusted for Insurance segment expense and Rep and warrant expense. In the denominator, total net revenue is adjusted for Insurance segment revenue and Core OID. See page 13 for the combined ratio for the Insurance segment which management uses as a primary measure of underwriting profitability for the Insurance segment.

Notes on Non-GAAP and Other Financial Measures Supplemental Common Equity Tier 1 (“CET1”) capital fully phased-in: Under the Basel III regulatory framework as adopted in the United States, banking organizations like the company are required to comply with a minimum ratio of common equity tier 1 capital to risk-weighted assets (CET1 Capital Ratio). Common equity tier 1 capital generally consists of common stock (plus any related surplus and net of any treasury stock), retained earnings, accumulated other comprehensive income, and minority interests in the common equity of consolidated subsidiaries, subject to specified conditions and adjustments. The obligation to comply with the minimum CET1 Capital Ratio is subject to ongoing transition periods and other provisions under Basel III. Management believes that both the transitional CET1 Capital Ratio and the fully phased-in CET1 Capital Ratio are helpful to readers in evaluating the company’s capital utilization and adequacy in absolute terms and relative to its peers. The fully phased-in CET1 Capital Ratio is a non-GAAP financial measure that is reconciled to the transitional CET1 Capital Ratio above.

Notes on Non-GAAP and Other Financial Measures Supplemental Non-GAAP line items walk to Core pre-tax income, a non-GAAP financial measure that adjusts pre-tax income. See page 23 for definitions.

Notes on Non-GAAP and Other Financial Measures Supplemental Excludes accelerated OID. See page 23 for definitions. Note: Accelerated OID and repositioning items primarily related to the extinguishment of high-cost legacy debt and strategic activities. Equity fair value adjustments related to ASU 2016-01 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 23 for definitions.
