Ally believes the non-GAAP financial measures defined here are important to the reader of the Consolidated Financial Statements, but these are supplemental to and not a substitute for GAAP measures.

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) 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 1/1/2018 in which such adjustments were recognized through other comprehensive income, a component of equity, (4) adjusts for Repositioning and other which are primarily related to the extinguishment of high cost legacy debt, strategic activities and significant other one-time items and (5) excludes significant discrete tax items that do not relate to the operating performance of the core businesses.

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, rep and warrant expense and repositioning and other which are primarily related to the extinguishment of high cost legacy debt, strategic activities and significant other one-time items. In the denominator, total net revenue is adjusted for Insurance segment revenue and Core OID. See Reconciliation to GAAP on page 7 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 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 deferred tax liabilities (DTLs) and (2) tax-effected Core OID balance to reduce tangible common equity in the event the corresponding discounted bonds are redeemed/tendered. 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 the future periods would flow through the financial statements at a 21% rate versus a previously modeled 35% rate. See Reconciliation to GAAP on page 7 for calculation methodology and details.

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. 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, strategic activities and significant other one-time items, significant discrete tax items, and tax-effected changes in equity investments measured at fair value. See Reconciliation to GAAP on page 6 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 7 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 7 for calculation methodology and details.

Core Pre-tax Income / (Loss) is a non-GAAP financial measure that adjusts pre-tax income from continuing operations by excluding (1) Core OID, (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 1/1/2018 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. 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 the Pre-Tax Income / (Loss) by Segment Table on page 3 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 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 significant discrete tax items including tax reserve releases, which aligns with the methodology used in calculating adjusted earnings per share.

Corporate and Other primarily consists of activity related to centralized corporate treasury activities such as management of the cash and corporate investment securities and loan portfolios, short- and long-term debt, retail and brokered deposit liabilities, derivative instruments, the amortization of the discount associated with new debt issuances and bond exchanges, and the residual impacts of our corporate FTP and treasury ALM activities. Corporate and Other also includes certain equity investments, the management of our legacy mortgage portfolio, and reclassifications and eliminations between the reportable operating segments. Subsequent to June 1, 2016, the revenue and expense activity associated with Ally Invest was included within the Corporate and Other segment. Subsequent to October 1, 2019, the revenue and expense activity associated with Health Credit Services (rebranded Ally Lending) was included within the Corporate and Other segment.

Estimated impact of CECL on regulatory capital per interim 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 provides an alternative option for banks to temporarily delay the impacts of CECL, relative to the incurred loss methodology for estimating the allowance for credit losses, on regulatory capital. 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 interim 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.

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.

Net Financing Revenue (excluding OID) excludes Core OID.

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 6 for calculation methodology & details.

GAAP and Core Results: Quarterly 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). 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 (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 pages 28 and 30 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 30 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 32 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 31 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, Core OID, and repositioning and other. See page 33 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 35 for calculation methodology and details.

Supplemental

Results by Segment Core OID for all periods shown is applied to the pre-tax income of the Corporate and Other segment. Change in fair value of equity securities impacts the Insurance and Corporate Finance segments. Reflects 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. See pages 34 for details. Repositioning and other include a $50 million Goodwill impairment at Ally Invest in 2Q 20. Core pre-tax income is a non-GAAP financial measure that adjusts pre-tax income from continuing operations for Core OID, equity fair value adjustments related to ASU 2016-01, and, repositioning and other which are primarily related to the extinguishment of high cost legacy debt, strategic activities and significant other one-time items. 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 34 for calculation methodology and details. Supplemental Incl. $50M Ally Invest goodwill impairment

Interest Rate Sensitivity Supplemental Net financing revenue impacts reflect a rolling 12-month view. See page 28 for additional details. Gradual changes in interest rates are recognized over 12 months. The impact of the downward rate shocks is impacted by the current low interest rate environment, which limits absolute declines in rates.

GAAP does not prescribe a method for calculating individual elements of deferred taxes for interim periods; therefore, these balances are estimates. Primarily book / tax timing differences, including loan loss reserves impact of ~$0.3 billion related to CECL implementation. Deferred Tax Asset & Effective Tax Rate Supplemental Note: Significant discrete tax items do not relate to the operating performance of the core businesses. 2Q 20 effective tax rate was primarily impacted by a $50 million nondeductible Goodwill impairment. Excluding the nondeductible $50 million Goodwill impairment, the adjusted effective tax rate would be 24.6% 2Q 19 effective tax rate was impacted primarily due to a release of valuation allowance on foreign tax credit carryforwards during the second quarter of 2019. Ally’s effective tax rate was -18.2% for 2Q 19; excluding the discrete tax benefit of $201 million (0.50 EPS impact), the adjusted effective tax rate would be 22.5%, which represents a non-GAAP financial measure.

Notes on Non-GAAP and Other Financial Measures Supplemental 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. 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 34 for calculation methodology and details. 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. See page 30 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 35 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 35 for calculation methodology and details. Accelerated issuance expense (Accelerated OID) is the recognition of issuance expenses related to calls of redeemable debt. 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-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 31 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; excludes non-recurring escheatment. 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, 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.

Notes on Non-GAAP and Other Financial Measures Supplemental 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. Estimated impact of CECL on regulatory capital per interim 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 provides 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. 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 interim 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.

GAAP to Core Results: Adjusted EPS - Quarterly 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) adjusts for 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, and (5) excludes significant discrete tax items that do not relate to the operating performance of the core businesses.

GAAP to Core Results: Adjusted TBVPS - Quarterly 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, and (2) tax-effected Core OID balance to reduce tangible common equity in the event the corresponding discounted bonds are redeemed/tendered. 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. Ally adopted CECL on January 1, 2020. 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.

GAAP to Core Results: Core ROTCE - Quarterly 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 significant 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, 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 component of equity, and significant discrete tax items. In the denominator, GAAP shareholder’s equity is adjusted for goodwill and identifiable intangibles net of DTL, Core OID balance, and net DTA.

GAAP to Core Results: Adjusted Efficiency Ratio - Quarterly 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 Rep and warrant expense, Insurance segment expense, and repositioning and other which are primarily related to the extinguishment of high cost legacy debt, strategic activities and significant other one-time items. In the denominator, total net revenue is adjusted for Core OID and Insurance segment revenue. See page 18 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 Non-GAAP line items walk to Core pre-tax income, a non-GAAP financial measure that adjusts pre-tax income. See page 28 for definitions.

Notes on Non-GAAP and Other Financial Measures Supplemental Excludes accelerated OID. See page 28 for definitions. Note: 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. Repositioning and other which are primarily related to the extinguishment of high cost legacy debt, strategic activities and significant other one-time items. See page 28 for definitions.
