DuPont ( DD) took up guidance dramatically Wednesday, citing unexpected strength in its agriculture and nutrition segment and higher volume across its business lines.

Excluding one-time items, the chemical company expects to earn 95 cents a share. That compares with previous earnings guidance of 65 cents to 75 cents a share and the Thomson First Call analyst consensus of 73 cents a share. The company's stock rose $1.21, or 2.8%, to $44.90 on the Instinet premarket session.

The company's first-quarter bottom line will include a charge of 14 cents a share to set up a reserve for litigation involving DuPont Dow Elastomers, and a charge of 2 cents a share for an expected settlement of litigation involving its coatings and color technologies unit. DuPont also expects more adjustments related to its spinoff of Invista.

For the full year, DuPont expects to earn $2.10 to $2.30 a share before charges, up 10 cents a share from previous guidance. Analysts surveyed by Thomson First Call were forecasting earnings of $2.16 a share for the full year.
