Mosaic's stock jumped more than 5 percent Thursday after the company reported fourth-quarter earnings that beat analysts' expectations, despite being hit by the effects of a strong dollar and low grain prices.
The Plymouth-based company is a global producer of phosphate and potash crop nutrients for agricultural operations.
Fertilizer companies have been struggling with falling prices, mainly because of low grain prices and weak currencies in Brazil and other countries. For Mosaic, that meant fourth-quarter net earnings of $155 million, down from $361 million during the same period in 2014.
The company also reported adjusted earnings of 53 cents per share during the October-to-December period, compared with 87 cents a year earlier. Net sales fell 9 percent to $2.16 billion, down from $2.38 billion last year.
Analysts surveyed by Thomson Reuters had expected earnings per share of 44 cents for the quarter and slightly lower revenue of $1.9 billion.
Company President and CEO Joc O'Rourke said the fourth-quarter results reflect the cyclical and seasonal nature of agriculture and the fertilizer business.
"Clearly, farm economics are under a little pressure, but more relevant to us are the huge macroeconomic impacts of currency changes around the world," he said in an interview.
For the year ending Dec. 31, Mosaic reported net sales of $8.9 billion, down from $9.1 billion the previous year, and 2015 earnings of $2.78 per share, compared to $2.68 per share the year before.
