GM Reports Net Income of $1.7 Billion

Net income of $1.03 per share; EBIT-adjusted of $2.2 billion

DETROIT – General Motors Co. (NYSE: GM) today announced third quarter net income attributable to common stockholders of $1.7 billion, or $1.03 per fully-diluted share. In the third quarter of 2010, GM’s net income attributable to common stockholders was $2.0 billion, or $1.20 per fully-diluted share.

Net revenue increased $2.6 billion to $36.7 billion, compared with the third quarter of 2010. Earnings before interest and tax (EBIT) adjusted was $2.2 billion, compared with $2.3 billion in the third quarter of 2010. There were no special items in either period.

“GM delivered a solid quarter thanks to our leadership positions in North America and China, where we have grown both sales and market share this year. But solid isn’t good enough, even in a tough global economy,” said Dan Akerson, chairman and CEO. “Our overall results underscore the work we have to do to leverage our scale and further improve our margins everywhere we do business.”

GM Results Overview (in billions except for per share amounts)

For the quarter, automotive cash flow from operating activities was $1.8 billion and automotive free cash flow was $0.3 billion.

GM ended the quarter with very strong total automotive liquidity of $38.8 billion. Automotive cash and marketable securities, including Canadian Health Care Trust restricted cash, was $33.0 billion compared with $33.8 billion at the end of the second quarter of 2011.

Based on current industry outlook, the company expects EBIT-adjusted results in the fourth quarter of 2011 will be similar to the fourth quarter of 2010 as a result of seasonal trends in North America and weakness in Europe. GM also expects to record a special item in the fourth quarter to recognize a $800 million non-cash settlement gain related to a Canadian Health Care Trust settlement.

Calendar-year EBIT-adjusted for 2011 is expected to show solid improvement over 2010, as previously indicated. However, the company does not expect to achieve its target to break even on an EBIT-adjusted basis before restructuring charges in Europe, due to deteriorating economic conditions.

“GM continues to execute the plan we outlined for investors in 2010,” said Dan Ammann, senior vice president and CFO. “That includes investing in our products, further strengthening our balance sheet, generating cash and profits each quarter, and maintaining our low break-even level. The next level of performance will come as we systematically eliminate complexity and cost throughout the organization.”

General Motors Co. (NYSE:GM, TSX: GMM) and its partners produce vehicles in 30 countries, and the company has leadership positions in the world’s largest and fastest-growing automotive markets. GM’s brands include Chevrolet and Cadillac, as well as Baojun, Buick, GMC, Holden, Isuzu, Daewoo, Jiefang, Opel, Vauxhall and Wuling.

Forward-Looking Statements

In this press release and in related comments by our management, our use of the words “expect,” “anticipate,” “possible,” “potential,” “target,” “believe,” “commit,” “intend,” “continue,” “may,” “would,” “could,” “should,” “project,” “projected,” “positioned” or similar expressions is intended to identify forward-looking statements that represent our current judgment about possible future events. We believe these judgments are reasonable, but these statements are not guarantees of any events or financial results, and our actual results may differ materially due to a variety of important factors. Among other items, such factors might include: our ability to realize production efficiencies and to achieve reductions in costs as a result of our restructuring initiatives and labor modifications; our ability to maintain quality control over our vehicles and avoid material vehicle recalls; our ability to maintain adequate liquidity and financing sources and an appropriate level of debt, including as required to fund our planned significant investment in new technology; the ability of our suppliers to timely deliver parts, components and systems; our ability to realize successful vehicle applications of new technology; and our ability to continue to attract new customers, particularly for our new products. GM’s most recent annual report on Form 10-K and quarterly reports on Form 10-Q provides information about these and other factors, which we may revise or supplement in future reports to the SEC.

Supplemental Material

(Unaudited)

The accompanying tables and charts for securities analysts include earnings before interest and taxes (EBIT), EBIT adjusted and Automotive free cash flow which are not prepared in accordance with Accounting Principles Generally Accepted in the United States of America (U.S. GAAP) and have not been audited or reviewed by GM’s independent auditors. EBIT, EBIT adjusted and Automotive free cash flow are considered non-GAAP financial measures.

Management believes these non-GAAP financial measures provide meaningful supplemental information regarding GM’s operating results because they exclude amounts that management does not consider part of operating results when assessing and measuring the operational and financial performance of the organization. Management believes these measures allow it to readily view operating trends, perform analytical comparisons and benchmark performance among geographic regions. Accordingly, GM believes these non-GAAP financial measures are useful in allowing for greater transparency of GM’s core operations and they are therefore used by management in its financial and operational decision-making.

While management believes that these non-GAAP financial measures provide useful information, they are not operating measures under U.S. GAAP and there are limitations associated with their use. GM’s calculation of these non-GAAP financial measures may not be completely comparable to similarly titled measures of other companies due to potential differences between companies in their method of calculation. As a result, the use of these non-GAAP financial measures has limitations and should not be considered in isolation from, or as a substitute for, other measures such as Net income or Net income attributable to common stockholders. Due to these limitations, these non-GAAP financial measures are used as a supplement to U.S. GAAP measures.
