DuPont Reports Second Quarter Earnings Per Share of $1.04;
Reaffirms Full Year Outlook

Highlights

• Second quarter 2007 earnings per share were $1.04, compared with $1.04 in the second quarter of 2006.

• Earnings per share grew 3 percent to $1.04 from $1.01, excluding a $0.03 per share significant item in the prior-year quarter.

• Sales grew 6 percent to $7.9 billion, reflecting 1 percent volume growth, 2 percent higher local selling prices and a 3 percent currency benefit.

• Sales growth in all regions outside the United States more than offset lower U.S. volumes resulting from continuing weakness in housing and automotive markets.

• The benefit of higher local selling prices was offset by a rise in energy and ingredient costs.

• Fixed costs as a percentage of sales decreased 120 basis points from the prior-year quarter.

• DuPont reaffirmed its full year 2007 earnings outlook of about $3.15 per share excluding significant items.

          “We are seeing the benefit of our global presence — capitalizing on strong routes to market in developing countries and building on our market-leading positions for businesses that serve multiple industries,” said Charles O. Holliday, Jr., DuPont chairman and chief executive officer. “We generated solid volume growth in all regions outside the United States and increased local selling prices for the 14^th consecutive quarter while reducing fixed costs as a percentage of sales. We are executing our growth strategies and continuing to increase return on invested capital.”

Global Consolidated Sales and Net Income

          Consolidated net sales grew 6 percent to $7.9 billion in the quarter due to 2 percent higher local prices, a 1 percent increase in volume, and a 3 percent currency benefit. The 4 percent volume growth outside the United States was partly offset by lower volumes, primarily in the United States, from slower housing and auto markets. A summary of second quarter 2007 worldwide and regional sales performance is shown in the table below.

          Net income for the second quarter of 2007 was $972 million, or $1.04 per share. Second quarter 2006 net income was $975 million, or $1.04 per share, and included a $31 million, or $0.03 per share tax benefit. Excluding the tax benefit, second quarter 2006 net income was $944 million, or $1.01 per share. The year-over-year improvement in underlying results principally reflects higher local prices, favorable currency impact, volume growth outside the United States, and higher pharmaceutical income. These gains were partially offset by higher ingredient costs and increased cost investments primarily to accelerate biotech research and development, expand global sales coverage in seeds, and increase production capacity in Kevlar^® and Nomex^®, photovoltaics, and select China facilities.

Business Segment Performance

          Segment pre-tax operating income (PTOI) for the second quarter of 2007 grew 6 percent to $1.6 billion from $1.5 billion in the second quarter of 2006. Segment sales, PTOI, and related variances versus the second quarter of 2006 are shown in the following tables:

Agriculture & Nutrition

• Sales of $2.1 billion grew 7 percent driven by strong U.S. seed corn and cereal herbicides sales. These gains were partially offset by lower sales of soybeans and cotton herbicides due to reduced acres in North America.

• PTOI was $428 million versus $430 million in the second quarter 2006. Strong results in global crop protection products and North American seed corn were offset by lower soybean volumes and $33 million of growth investments. These investments were made to accelerate biotechnology trait development, to more rapidly integrate existing traits into leading germplasm and to strengthen seed sales coverage.

Coatings & Color Technologies

• Second quarter 2007 sales of $1.7 billion grew 5 percent reflecting 4 percent higher USD selling prices and 1 percent higher volume. Increased sales of refinish coatings and titanium dioxide outpaced the negative impact of the weak U.S. auto and housing markets.

• PTOI was $226 million, essentially equal to the prior year. Fixed cost reductions in OEM coatings and strong international sales were offset by weakness in U.S. auto and housing markets and increased ingredient and transportation costs.

4

Electronic & Communication Technologies

• Sales grew 4 percent to $979 million as volume growth in fluoroproducts and packaging graphics, favorable currency impact, and gains in photovoltaic markets were largely offset by lower refrigerant pricing and weakness in certain cell phone and semiconductor supply chains.

• PTOI was $176 million in the quarter and included the benefit of a $25 million pre-tax inventory valuation adjustment. The weakness reflects lower refrigerants pricing and softness in certain electronic materials markets, primarily for cell phones.

Performance Materials

• Sales grew 8 percent to $1.7 billion reflecting higher local selling prices and a favorable currency impact. Volume growth in Europe and Latin America offset lower demand in North America.

• PTOI increased 19 percent to $227 million primarily due to strong gains in the segment’s packaging, industrial polymer and elastomer product lines.

Safety & Protection

• Sales of $1.5 billion were up 4 percent reflecting a 4 percent increase in USD selling prices. Higher sales of aramids and construction materials outside the United States were offset by lower sales in U.S. housing markets.

• PTOI increased 3 percent to $318 million, principally reflecting strong earnings growth in aramid products, largely offset by lower earnings from U.S. housing markets, spending for hybrid membrane technology and capacity expansions in Kevlar^® and Nomex^®.

Share Repurchase Program Update

          The company has completed nearly 80 percent of its $5 billion share repurchase program announced October 2005. In the second quarter 2007, the company repurchased 5.9 million shares of its stock for $300 million. The total amount repurchased to date under this program is $3.9 billion, or approximately 90 million shares. The company expects to complete the remaining $1.1 billion of the program, consistent with its financial discipline principles, by the end of 2007.

Outlook

          DuPont reaffirms its outlook for 2007 full-year earnings per share of about $3.15, excluding a $0.06 per share charge for significant items in the first quarter 2007. For the second half of 2007, the company expects to benefit from continued growth outside the United States, higher local selling prices and ongoing fixed cost productivity gains. The company also anticipates continued softness in U.S. housing, higher ingredient costs and a higher base tax rate versus last year.

          “Our strong position as a global market leader in both developed and developing economies enabled us to deliver 9 percent earnings growth in the first half of the year,” Holliday said.

“We will achieve our outlook through cost productivity gains and by continuing to deliver competitive advantages to our customers through market-driven innovations.”

Use of Non-GAAP Measures

          Management believes that measures of income excluding significant items (“non-GAAP” information) are meaningful to investors because they provide insight with respect to ongoing operating results of the company. Such measurements are not recognized in accordance with generally accepted accounting principles (GAAP) and should not be viewed as an alternative to GAAP measures of performance. Reconciliations of non-GAAP measures to GAAP are provided in Schedule D.

          DuPont is a science-based products and services company. Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere. Operating in more than 70 countries, DuPont offers a wide range of innovative products and services for markets including agriculture and food; building and construction; communications; and transportation.
