DuPont Records Strong Earnings Growth in 4Q and Full Year 2006; Company Expects to Grow 2007 Earnings to $3.15 Per Share

WILMINGTON, Del., Jan. 23 /PRNewswire-FirstCall/ --

Highlights - Fourth quarter 2006 earnings were $.94 per share, compared to fourth quarter 2005 earnings of $.16 per share. - Excluding significant items, fourth quarter 2006 earnings were $.45 per share, compared to the $.13 per share hurricane-impacted fourth quarter 2005. - Sales grew 8 percent reflecting 4 percent higher volume, 2 percent higher local selling prices and 2 percent favorable currency. - Raw material costs were about $80 million or 3 percent higher than fourth quarter 2005. - Fourth quarter 2006 fixed costs were flat and improved as a percentage of sales by 4 percentage points versus 2005. - Segment pretax operating margin excluding significant items improved 4 percentage points versus fourth quarter 2005. - Full-year 2006 earnings were $3.38 per share versus $2.07 in 2005. Earnings before significant items were $2.88 per share for the year 2006, compared to $2.34 for 2005, up 23 percent.

"This was a strong fourth quarter for our company with improved business results across the board and strong growth outside of the United States," said Charles O. Holliday, Jr., DuPont chairman and chief executive officer. "For the year, earnings per share grew 23 percent and return on invested capital increased significantly, reflecting the positive impact of executing our growth strategies and our actions to accelerate value creation. We will build on this momentum in 2007."

Global Consolidated Net Income and Sales

Total company net income for the fourth quarter 2006 was $871 million, or $.94 per share. Fourth quarter 2005 net income was $154 million, or $.16 per share.

The increase in fourth quarter 2006 net income reflects 8 percent higher sales, flat fixed costs, significantly improved operating results in the Agriculture & Nutrition and Performance Materials platforms and recovery from the fourth quarter 2005 impact of Gulf Coast hurricanes Katrina and Rita.

Fourth quarter net income included $449 million, or $.49 per share from significant items (see Schedule B), principally tax benefits realized and insurance recoveries, partly offset by charges for restructuring, an asset impairment, and adjustments having considered the provisions of the recently issued SEC Staff Accounting Bulletin (SAB) 108. Fourth quarter 2005 net income included a significant item benefit of $28 million or $.03 per share (see Schedule B).

Consolidated net sales for the fourth quarter were $6.3 billion, up 8 percent versus the fourth quarter 2005 including 2 percent higher local selling prices, and a 2 percent currency benefit. Worldwide volumes grew 4 percent, primarily from strong volume growth outside the United States reflecting higher sales of engineering and packaging polymers, elastomers, and crop protection and seed products. Volume in the United States reflects lower sales into residential construction and automotive markets, largely due to customers' efforts to reduce inventories. Global volume growth also reflects post-hurricane recovery, principally in the titanium dioxide business.

Agriculture & Nutrition - PTOI loss of $350 million reflects normal seasonality and significant items, principally a $194 million restructuring charge. Excluding the significant items, PTOI increased $114 million, largely due to higher sales in both seeds and crop protection chemicals. - Fourth quarter sales increased 17 percent to $1.1 billion. In seed products, increased sales reflect higher prices, share gains in the Southern Hemisphere and an earlier start to the 2007 corn marketing season in Western Europe. For crop protection chemicals, higher sales largely reflect gains in the Southern Hemisphere, including new products, and strong U.S. and European cereal herbicide sales, net of lower U.S. corn herbicide sales. Coatings & Color Technologies - PTOI was $282 million versus $153 million earned in the hurricane- impacted fourth quarter 2005. Excluding significant items, PTOI increased 31 percent due to higher titanium dioxide sales and a gain on the sale of assets, which together more than offset the impact of lower automotive OEM coatings volumes. - Fourth quarter sales of $1.6 billion were up 7 percent. Higher volumes in the titanium dioxide business and higher prices in the coatings businesses more than offset lower volume in automotive OEM coatings. Electronic & Communication Technologies - PTOI grew to $118 million due to gains in fluoroproducts, electronic materials and display technologies, partially offset by lower imaging technologies results. - Sales grew 3 percent to $911 million due to favorable currency and higher local prices. Sales growth was particularly strong in Europe for electronic materials. Performance Materials - PTOI grew to $126 million from the $55 million earned in the hurricane- impacted fourth quarter 2005, primarily due to gains in performance elastomers and packaging and industrial polymers. - Sales rose 7 percent to $1.7 billion, reflecting volume, price and currency gains. Sales growth was particularly strong in Asia Pacific and Europe. Safety & Protection - PTOI was $211 million versus $212 million earned in the prior year. Excluding significant items, PTOI was $245 million, up 16 percent reflecting strong sales and fixed cost productivity. - Fourth quarter sales were up 5 percent to $1.4 billion reflecting 2 percent higher volume and 3 percent higher USD prices. All regions outside the United States grew at modest rates, offsetting a slight decline in the United States.

Outlook

The company reaffirmed its 2007 outlook of about $3.15 earnings per share. In 2007, the company expects modest volume gains as continued growth outside the United States is expected to outweigh slower growth in U.S. housing and automotive markets. Volatility in energy and ingredient costs is expected to continue, but for the full year, average costs are assumed to be about equal to 2006.

The company will continue to advance its innovation projects, with a high priority on its differentiated bio-materials and biofuels technology platform. Additional customer-driven product launches are expected to help extend the company's three-year positive pricing trend.

The company's 2007 cost productivity goal is to achieve savings of over $400 million to offset inflation and contribute to growth project spending. The company will continue to adjust capital and resource allocation among its businesses in an effort to further enhance return on invested capital. In addition, the company will continue implementing its previously announced restructuring programs in Coatings & Color Technologies and Agriculture & Nutrition.

"We will build on our momentum in 2007, strengthened by the progress we have made with our productivity initiatives and growth strategies," Holliday said. "We will continue our intense focus on customer-driven product innovations and cost productivity while advancing our exciting pipeline of new products, services, and technologies."

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 E.

Pretax amounts by segment for the insurance recoveries were: $7 - Agriculture & Nutrition; $19 - Coatings & Color Technologies; $10 - Electronic & Communication Technologies; $12 - Performance Materials; and $13 - Safety & Protection. Total year 2005 includes a gain of $31 from sale of certain North American assets in the Safety & Protection segment, a gain of $23 resulting from the disposition of certain assets of DuPont Dow Elastomers LLC (DDE) to the Dow Chemical Company, a $28 benefit related to interest on certain prior year tax contingencies, and a gain of $48 resulting from the sale of the company's equity interest in DuPont Photomasks, Inc. (d) Fourth quarter 2006 includes a restructuring charge of $194 in the Agriculture & Nutrition segment associated with the investment and streamlining program announced during the quarter. The charge consists of employee separation and employee related costs of $64, primarily associated with the elimination of approximately 1,500 positions in the segment, and asset impairment costs of $130. Fourth quarter 2006 also includes an asset impairment charge of $47 associated with an underperforming industrial chemicals asset held for sale within the Safety & Protection segment.

(f) Total year 2005 includes a net gain of $62 relating to the disposition of four equity affiliates, partly offset by other separation activities. (g) Year-to-date 2005 includes $14 of operating income related to certain DDE assets that were disposed of on June 30, 2005. (h) Fourth quarter 2006 includes a benefit of $479 for reversal of accruals related to tax settlements, reversals of tax valuation allowances, and the finalization of taxes related to the Company's repatriation of foreign earnings under the American Jobs Creation Act of 2004 (AJCA). Year-to-date 2006 also includes a tax benefit of $31 associated with an increase in the deferred tax assets of a European subsidiary for a tax basis investment loss recognized on the local tax return and the reversal of $44 of income taxes associated with favorable settlement of certain prior-year tax contingencies which had been previously reserved. Fourth quarter 2005 includes a benefit of $28 associated with lower than expected costs related to AJCA. Year-to-date 2005 includes $292 for repatriation of $9.1 billion under AJCA and a net tax benefit of $24 related to certain prior year tax contingencies previously reserved. (i) In the fourth quarter of 2006, the company adopted the provisions of FSP AUG AIR-1, "Accounting for Planned Major Maintenance Activities," which prohibits the use of the accrue-in-advance method. Previously, the company had principally accrued in advance for significant planned major maintenance activities. As permitted by FSP AUG AIR-1, the company has early adopted the FSP's provisions and retrospectively applied the defer and amortize method effective January 1, 2005, and as a result of the retrospective application, the fourth quarter and full year 2005 results differ from those previously reported. For the three and twelve months ended December 31, 2005, net income increased by $1 and $3, respectively, as a result of adoption of this FSP; however, there was no change to earnings per share amounts in either period. For the nine months ended September 30, 2006, there was no change to net income or earnings per share amounts previously reported. Retrospective application prior to January 1, 2005 was impractical due to the divestiture of INVISTA in 2004.
