St. Louis-based Monsanto reported earnings per share for the second quarter ended February 28 of $1.60 on an as-reported basis, and $1.70 on an ongoing basis.
Analysts were expecting $1.73 a share, according to Thomson Reuters I/B/E/S, and $1.70 on a fully reported basis.
The company said full-year ongoing earnings per share would likely come in at the low end of its previously stated range of $3.10 to $3.30, and Monsanto officials said it was unlikely to meet its goal of doubling 2007 gross profit by 2012.
Shares rose 1.4 percent to $70.49 in premarket trading after the results.
