Information Relevant to this Presentation Cautionary Note on Forward-Looking Statements: This presentation and related comments by management may include “forward- looking statements” within the meaning of the U.S. federal securities laws. Forward-looking statements are any statements other than statements of historical fact. Forward-looking statements represent our current judgement about possible future events and are often identified by words such as “aim”, “anticipate,” “appears,” “approximately,” “believe,” “continue,” “could,” “designed,” “effect,” “estimate,” “evaluate,” “expect,” “forecast,” “goal,” “initiative,” “intend,” “may,” “objective,” “outlook,” “plan,” “potential,” “priorities,” “project,” “pursue,” “seek,” “should,” “target,” “when,” “will,” “would,” or the negative of any of those words or similar expressions. In making these statements we rely upon assumptions and analysis based on our experience and perception of historical trends, current conditions and expected future developments, as well as other factors we consider appropriate under the circumstances. We believe these judgements are reasonable, but these statements are not guarantees of any future events or financial results, and our actual results may differ materially due to a variety of important factors, many of which are described in our most recent Annual Report on Form 10-K and our other filings with the Securities and Exchange Commission. We caution readers not to place undue reliance on forward-looking statements. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update publicly or otherwise revise any forward-looking statements, whether as a result of new information, future events or other factors that affect the subject of these statements, except where we are expressly required to do so by law. Non-GAAP Financial Measures: See our most recent Annual Report on Form 10-K and our other filings with the Securities and Exchange Commission for a description of EBIT-adjusted, a non-GAAP measure used in this presentation, along with a description of various uses for such measure. Our calculation of EBIT-adjusted is set forth on the Appendix of this presentation and may not be comparable to similarly titled measures of other companies due to potential differences between companies in the method of calculation. As a result, the use of this non-GAAP measure has limitations and should not be considered superior to, in isolation from, or as a substitute for, related U.S. GAAP measures. When we present our total company EBIT-adjusted, GMF is presented on EBT- adjusted basis. Additional Information: In this presentation and related comments by management, references to “record” or “best” performance (or similar statements) refer to General Motors Company as established in 2009 on a continuing operations basis. 21
