GM Reports First Quarter 2010 Results

GM achieves net income of $0.9 billion and EPS of $1.66

DETROIT, Mich. – General Motors Company today announced its first quarter 2010 results, marked by revenue of $31.5 billion and operating income of $1.2 billion. Net income attributable to common stockholders was $0.9 billion, resulting in earnings per share on a diluted basis of $1.66.

GM’s first quarter adjusted earnings before interest and tax (EBIT) was $1.7 billion, after adjusting for the favorable impact of the sale of the Saab brand.

GM North America had EBIT in the first quarter 2010 of $1.2 billion, up from a loss of $3.4 billion in the fourth quarter 2009. GM Europe had a loss before interest and taxes of $0.5 billion; an improvement of $0.3 billion from the fourth quarter. GM International Operations posted EBIT of $1.2 billion, up $0.5 billion from the fourth quarter.

Cash flow from operating activities was $1.7 billion and after adjusting for capital expenditures of $0.7 billion, free cash flow was $1.0 billion. GM ended the first quarter with $35.7 billion in cash and marketable securities, including funds in escrow.

“We’re pleased with our first quarter performance, in particular achieving profitability,” said Chris Liddell, vice chairman and chief financial officer. “In North America we are adding production to keep up with strong demand for new products in our four brands. We’re also steadily growing in emerging markets, keeping our costs under control, generating positive cash flow and maintaining a strong balance sheet. These are all important steps as we lay the foundation for a successful GM.”

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 planning significant investment in new technology; our ability to realize successful vehicle applications of new technology; and our ability to comply with the continuing requirements related to U.S. and other government support.

GM’s most recent annual report on Form 10-K and quarterly report 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 (loss) before interest and taxes (EBIT), adjusted EBIT and 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, adjusted EBIT and 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, benchmark performance among geographic regions and assess whether GM’s plan to return to profitability is on target. 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 the 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 (loss) or Net income (loss) attributable to common stockholders. Due to these limitations, these non-GAAP financial measures are used as a supplement to U.S. GAAP measures.
