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 our statements about targets and expectations for various financial and operating metrics. 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, 2016, 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 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.

Our use of the term “loans” describes all of the products associated with our direct and indirect lending activities. The specific products include loans, retail installment sales contracts, lines of credit, leases, and other financing products. The term “lend” or “originate” refers to our direct origination of loans or our purchase or acquisition of loans.

Note: Numbers may not foot due to rounding

(1) Basel III rules became effective on January 1, 2015, subject to transition provisions primarily related to deductions and adjustments impacting CET1 capital and Tier 1 capital

(2) 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.

(3) Represents a non-GAAP financial measure. 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 unamortized Core OID and net deferred tax asset.

(4) Represents a non-GAAP financial measure. Ally defines tangible assets as total assets less goodwill and intangible assets, net of deferred tax liabilities.

(1) Includes shares related to share-based compensation that vested but were not yet issued

(2) Core net income attributable to common shareholders is a non-GAAP financial measure that serves as the numerator in the calculations of Adjusted EPS and Core ROTCE and that, like those measures, is believed by management to help the reader better understand the operating performance of the core businesses and their ability to generate earnings. Core net income attributable to common shareholders adjusts GAAP net income attributable to common shareholders for discontinued operations net of tax, tax-effected Core OID, 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.

(3) Adjusted earnings per share (Adjusted EPS) is a non-GAAP financial measure that adjusts GAAP EPS for revenue and expense items that are typically strategic in nature or that management otherwise does not view as reflecting the operating performance of the company. Management believes Adjusted EPS can help the reader better understand the operating performance of the core businesses and their ability to generate earnings. 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 certain discrete tax items that do not relate to the operating performance of the core businesses, and (5) 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.

(4) 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.

(5) 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.

(6) Accelerated issuance expense (Accelerated OID) is the recognition of issuance expenses related to calls of redeemable debt.

(7) Repositioning items are primarily related to the extinguishment of high-cost legacy debt and strategy activities.

(1) 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.

(1) 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.

(2) Normalized common equity is a non - GAAP measure calculated using 2 period average

(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 utilized a static 34% tax rate for purposes of calculating Core ROTCE through 4Q 2015. As of 1Q 2016, 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.

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 items primarily related to the extinguishment of high-cost legacy debt and strategic activities, certain discrete tax items and preferred stock capital actions.

2. 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.

(1) 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, repositioning items primarily related to strategic activities and rep and warrant expense. In the denominator, total net revenue is adjusted for Insurance segment revenue, repositioning items primarily related to the extinguishment of high-cost legacy debt and Core OID. See page 11 for the combined ratio for the Insurance segment which management uses as a primary measure of underwriting profitability for the Insurance business.
