Updated from 6:19 a.m. EDTDuPont ( DD) said first-quarter earnings fell 59% to $489 million, or 54 cents a share, as strong results in agriculture and nutrition, and its pharmaceuticals division, were partially offset by a "severe decline" in global industrial demand. Sales at the chemicals company in the quarter fell 17% to $7.27 billion from $8.77 billion. Analysts surveyed by Thomson Reuters expected Dupont to earn 52 cents a share in the first quarter. The company said it revised its earnings outlook lower to a range of $1.70 to $2.10 a share on expectations of continuing difficult market conditions "with the exception of global agriculture markets." It previously expected to earn $2 to $2.50 a share. Analysts expect 2009 earnings of $1.88 a share. DuPont also said it plans to increase its efforts to cut fixed costs by $1 billion, up from $730 million.
