Nutrien Ltd (NTR.N), created from the merger of fertilizer makers Agrium Inc and Potash Corp of Saskatchewan this year, said it expected full-year 2018 EBITDA of US$3.2 billion to US$3.7 billion.

Nutrien also said fourth-quarter net earnings for Agrium fell to US$18 million, or 13 cents per share, in the fourth quarter ended Dec. 31 from US$67 million, or 49 cents U.S. per share, a year earlier.

Potash Corp reported a net loss from continuing operations of US$120 million, or 14 cents U.S. per share, from a profit of US$13 million, or 2 cents U.S. per share, a year earlier.

Agrium's total sales rose 9.5 per cent to US$2.45 billion, while Potash Corp's sales were up 2 per cent at US$1.08 billion.

The results are the first since the closing of the merger in January.
