1Q 2023 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-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 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, 2022, 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. 2

1Q 2023 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 Statements, but which are supplemental to and not a substitute for GAAP measures: Accelerated issuance expense (Accelerated OID), Adjusted earnings per share (Adjusted EPS), Adjusted efficiency ratio, Adjusted noninterest expense, Adjusted other revenue, Adjusted tangible book value per share (Adjusted TBVPS), Adjusted total net revenue, Core net income attributable to common shareholders, Core original issue discount (Core OID) amortization expense, Core outstanding original issue discount balance (Core OID balance), Core pre-provision net revenue (Core PPNR), Core pre-tax income, Core return on tangible common equity (Core ROTCE), Investment income and other (adjusted), Net financing revenue (excluding Core OID), Net interest margin (excluding Core OID), Pre-provision net revenue (PPNR), and Tangible Common Equity. 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) Accelerated issuance expense (Accelerated OID) is the recognition of issuance expenses related to calls of redeemable debt. 2) 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 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) change in fair value of equity securities, (5) excludes significant discrete tax items that do not relate to the operating performance of the core businesses, and adjusts for preferred stock capital actions that have been taken by the company to normalize its capital structure, as applicable for respective periods. See page 42 for calculation methodology and details. 3) 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. See page 45 for calculation details. (1) 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, as applicable for respective periods. (2) In the denominator, total net revenue is adjusted for Core OID and Insurance segment revenue. See page 25 for the combined ratio for the Insurance segment which management uses as a primary measure of underwriting profitability for the Insurance segment. 4) Adjusted noninterest expense is a non-GAAP financial measure that adjusts GAAP noninterest expense for repositioning items. Management believes adjusted noninterest expense is a helpful financial metric because it enables the reader better understand the business' expenses excluding nonrecurring items. See page 47 for calculation methodology and details. 5) Adjusted other revenue is a non-GAAP financial measure that adjusts GAAP other revenue for OID expenses, repositioning, and change in fair value of equity securities. Management believes adjusted other revenue is a helpful financial metric because it enables the reader to better understand the business' ability to generate other revenue. See page 47 for calculation methodology and details. 36

1Q 2023 Preliminary Results Supplemental Notes on Non-GAAP Financial Measures 6) 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, 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. See pages 43 for calculation methodology and details. 7) Adjusted total net revenue is a non-GAAP financial measure that management believes is helpful for readers to understand the ongoing ability of the company to generate revenue. For purposes of this calculation, GAAP net financing revenue is adjusted by excluding Core OID to calculate net financing revenue ex. core OID. GAAP other revenue is adjusted for OID expenses, repositioning, and change in fair value of equity securities to calculate adjusted other revenue. Adjusted total net revenue is calculated by adding net financing revenue ex. core OID to adjusted other revenue. See page 47 for calculation methodology and details. 8) 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 pages 42 and 44 for calculation methodology and details. 9) 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 47 for calculation methodology and details. 10) 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 47 for calculation methodology and details. 11) Core pre-provision net revenue (Core PPNR) is a non-GAAP financial measure calculated by adding GAAP net financing revenue and GAAP other revenue and subtracting GAAP noninterest expense then adding Core OID and repositioning expenses, excluding provision for credit losses. Management believes that Core PPNR is a helpful financial metric because it enables the reader to assess the core business' ability to generate earnings to cover credit losses. See page 47 for calculation methodology and details. 12) 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) change in fair value of equity securities (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 46 for calculation methodology and details. 37

1Q 2023 Preliminary Results Supplemental Notes on Non-GAAP Financial Measures 13) 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. See page 44 for calculation details. (1) 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, change in fair value of equity securities, 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. 14) Investment income and other (adjusted) is a non-GAAP financial measure that adjusts GAAP investment income and other for repositioning, and the change in fair value of equity securities. Management believes investment income and other (adjusted) is a helpful financial metric because it enables the reader to better understand the business' ability to generate investment income. 15) Net financing revenue excluding core OID is calculated using a non-GAAP measure that adjusts net financing revenue by excluding Core OID. The Core OID balance is primarily related to bond exchange OID which excludes international operations and future issuances. Management believes net financing revenue ex. Core OID is a helpful financial metric because it enables the reader to better understand the business' ability to generate revenue. See page 47 for calculation methodology and details. 16) Net interest margin excluding core OID is calculated using a non-GAAP measure that adjusts net interest margin by excluding Core OID. The Core OID balance is primarily related to bond exchange OID which excludes international operations and future issuances. Management believes net interest margin ex. Core OID is a helpful financial metric because it enables the reader to better understand the business' profitability and margins. See page 11 for calculation methodology and details. 17) Pre-provision net revenue (PPNR) is a non-GAAP financial measure calculated by adding GAAP net financing revenue and GAAP other revenue then subtracting GAAP noninterest expense, excluding provision for credit losses. Management believes that PPNR is a helpful financial metric because it enables the reader to assess the business’ ability to generate earnings to cover credit losses and as it is utilized by Federal Reserve's approach to modeling within the Supervisory Stress Test Framework that generally follows U.S. generally accepted accounting principles (GAAP) and includes a calculation of PPNR as a component of projected pre-tax net income. See page 47 for calculation methodology and details. 18) 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 44 for calculation methodology and details. 38

1Q 2023 Preliminary Results Supplemental Notes on Other Financial Measures 1) Change in fair value of equity securities impacts the Insurance, Corporate Finance and Corporate and Other segments. The change reflects fair value adjustments to equity securities that are reported at fair value. Management believes the change in fair value of equity securities should be removed from select financial measures because it enables the reader to better understand the business’ ongoing ability to generate revenue and income. 2) Customer retention rate is the annualized 3-month rolling average of 1 minus the monthly attrition rate; excludes escheatment. 3) 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 extended through December 31, 2021. Beginning on January 1, 2022, we are 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 beginning January 1, 2022 are phasing in the regulatory capital impacts of CECL based on this five-year transition period. 4) Estimated retail auto originated yield is a 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. 5) 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 our SEC filings for more details. 6) 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. 7) Repositioning is primarily related to the extinguishment of high-cost legacy debt, strategic activities, and significant other one-time items. 8) 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/Stellantis dealers and direct-to-consumer loans. Note: Stellantis N.V. (“Stellantis”) announced January 17, 2021, following completion of the merger of Peugeot S.A. (“Groupe PSA”) and Fiat Chrysler Automobiles N.V. (“FCA”) on January 16, 2021, the combined company was renamed Stellantis; Nonprime – originations with a FICO® score of less than 620 39

Exhibit 99.3 FIRST QUARTER 2023 FINANCIAL SUPPLEMENT

ALLY FINANCIAL INC. FORWARD-LOOKING STATEMENTS AND ADDITIONAL INFORMATION This document 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 document 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 financial and operating metrics, 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, 2022, 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 document 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. 1Q 2023 Preliminary Results2

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) change in fair value of equity securities, (5) excludes significant discrete tax items that do not relate to the operating performance of the core businesses, and adjusts for preferred stock capital actions that have been taken by the company to normalize its capital structure, as applicable for respective periods.

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 and (3) Series G discount which reduces tangible common equity as the company has normalized its capital structure, as applicable for respective periods. 1Q 2023 Preliminary Results22

(3) 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. (1) 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, change in fair value of equity securities, significant discrete tax items, and preferred stock capital actions, as applicable for respective periods.

ALLY FINANCIAL INC. 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: Accelerated issuance expense (Accelerated OID), Adjusted earnings per share (Adjusted EPS), Adjusted efficiency ratio, Adjusted noninterest expense, Adjusted other revenue, Adjusted tangible book value per share (Adjusted TBVPS), Adjusted total net revenue, Core net income attributable to common shareholders, Core original issue discount (Core OID) amortization expense, Core outstanding original issue discount balance (Core OID balance), Core pre-provision net revenue (Core PPNR), Core pre-tax income, Core return on tangible common equity (Core ROTCE), Investment income and other (adjusted), Net financing revenue (excluding Core OID), Net interest margin (excluding Core OID), Pre-provision net revenue (PPNR), and Tangible Common Equity. These measures are used by management and we believe are useful to investors in assessing the company’s operating performance and capital. 1) Accelerated issuance expense (Accelerated OID) is the recognition of issuance expenses related to calls of redeemable debt. 2) 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 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) change in fair value of equity securities, (5) excludes significant discrete tax items that do not relate to the operating performance of the core businesses, and adjusts for preferred stock capital actions that have been taken by the company to normalize its capital structure, as applicable for respective periods. 3) 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. (1) 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, as applicable for respective periods. (2) In the denominator, total net revenue is adjusted for Core OID and Insurance segment revenue. 4) Adjusted noninterest expense is a non-GAAP financial measure that adjusts GAAP noninterest expense for repositioning items. Management believes adjusted noninterest expense is a helpful financial metric because it enables the reader better understand the business' expenses excluding nonrecurring items. 5) Adjusted other revenue is a non-GAAP financial measure that adjusts GAAP other revenue for OID expenses, repositioning, and change in fair value of equity securities. Management believes adjusted other revenue is a helpful financial metric because it enables the reader to better understand the business' ability to generate other revenue. 6) 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, 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. 7) Adjusted total net revenue is a non-GAAP financial measure that management believes is helpful for readers to understand the ongoing ability of the company to generate revenue. For purposes of this calculation, GAAP net financing revenue is adjusted by excluding Core OID to calculate net financing revenue ex. core OID. GAAP other revenue is adjusted for OID expenses, repositioning, and change in fair value of equity securities to calculate adjusted other revenue. Adjusted total net revenue is calculated by adding net financing revenue ex. core OID to adjusted other revenue. 8) Change in fair value of equity securities impacts the Insurance, Corporate Finance and Corporate and Other segments. The change reflects fair value adjustments to equity securities that are reported at fair value. Management believes the change in fair value of equity securities should be removed from select financial measures because it enables the reader to better understand the business’ ongoing ability to generate revenue and income. 9) 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. 1Q 2023 Preliminary Results25

ALLY FINANCIAL INC. 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: Accelerated issuance expense (Accelerated OID), Adjusted earnings per share (Adjusted EPS), Adjusted efficiency ratio, Adjusted noninterest expense, Adjusted other revenue, Adjusted tangible book value per share (Adjusted TBVPS), Adjusted total net revenue, Core net income attributable to common shareholders, Core original issue discount (Core OID) amortization expense, Core outstanding original issue discount balance (Core OID balance), Core pre-provision net revenue (Core PPNR), Core pre-tax income, Core return on tangible common equity (Core ROTCE), Investment income and other (adjusted), Net financing revenue (excluding Core OID), Net interest margin (excluding Core OID), Pre-provision net revenue (PPNR), and Tangible Common Equity. These measures are used by management and we believe are useful to investors in assessing the company’s operating performance and capital. 10) 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. 11) 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. 12) Core pre-provision net revenue (Core PPNR) is a non-GAAP financial measure calculated by adding GAAP net financing revenue and GAAP other revenue and subtracting GAAP noninterest expense then adding Core OID and repositioning expenses, excluding provision for credit losses. Management believes that Core PPNR is a helpful financial metric because it enables the reader to assess the core business' ability to generate earnings to cover credit losses. 13) 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) change in fair value of equity securities (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. 14) 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. (1) 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, change in fair value of equity securities, 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. 15) 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 extended through December 31, 2021. Beginning on January 1, 2022, we are 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 beginning January 1, 2022, are phasing in the regulatory capital impacts of CECL based on this five-year transition period. 16) Investment income and other (adjusted) is a non-GAAP financial measure that adjusts GAAP investment income and other for repositioning, and the change in fair value of equity securities. Management believes investment income and other (adjusted) is a helpful financial metric because it enables the reader to better understand the business' ability to generate investment income. 17) Net financing revenue excluding core OID is calculated using a non-GAAP measure that adjusts net financing revenue by excluding Core OID. The Core OID balance is primarily related to bond exchange OID which excludes international operations and future issuances. Management believes net financing revenue ex. Core OID is a helpful financial metric because it enables the reader to better understand the business' ability to generate revenue. 18) Net interest margin excluding core OID is calculated using a non-GAAP measure that adjusts net interest margin by excluding Core OID. The Core OID balance is primarily related to bond exchange OID which excludes international operations and future issuances. Management believes net interest margin ex. Core OID is a helpful financial metric because it enables the reader to better understand the business' profitability and margins. 1Q 2023 Preliminary Results26

ALLY FINANCIAL INC. 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: Accelerated issuance expense (Accelerated OID), Adjusted earnings per share (Adjusted EPS), Adjusted efficiency ratio, Adjusted noninterest expense, Adjusted other revenue, Adjusted tangible book value per share (Adjusted TBVPS), Adjusted total net revenue, Core net income attributable to common shareholders, Core original issue discount (Core OID) amortization expense, Core outstanding original issue discount balance (Core OID balance), Core pre-provision net revenue (Core PPNR), Core pre-tax income, Core return on tangible common equity (Core ROTCE), Investment income and other (adjusted), Net financing revenue (excluding Core OID), Net interest margin (excluding Core OID), Pre-provision net revenue (PPNR), and Tangible Common Equity. These measures are used by management and we believe are useful to investors in assessing the company’s operating performance and capital. 19) Pre-provision net revenue (PPNR) is a non-GAAP financial measure calculated by adding GAAP net financing revenue and GAAP other revenue then subtracting GAAP noninterest expense, excluding provision for credit losses. Management believes that PPNR is a helpful financial metric because it enables the reader to assess the business’ ability to generate earnings to cover credit losses and as it is utilized by Federal Reserve's approach to modeling within the Supervisory Stress Test Framework that generally follows U.S. generally accepted accounting principles (GAAP) and includes a calculation of PPNR as a component of projected pre-tax net income. 20) Repositioning is primarily related to the extinguishment of high-cost legacy debt, strategic activities and other one-time items. 21) 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. 1Q 2023 Preliminary Results27
