Revenue declined to $559.7 million from $581.2 million in the year-ago quarter. Analysts surveyed by FactSet had forecast earnings of $1.81 a share on revenue of $587.7 million. Nordson said it "now expects flat to modest organic sales growth and unfavorable foreign currency effects of approximately 2 percent on sales as compared to the prior year." Analysts expect annual revenue of $2.24 billion, or 0.8% down from a year ago. "As we approach the end of our fiscal year, the effect of recent macroeconomic trends has had a more significant impact than most anticipated, particularly on electronics end markets," said Michael Hilton, who served as Nordson's president and CEO until July 31, in a statement.
