MONTREAL - WSP Global Inc. (WSP.TO) says its fourth-quarter profit attributable to shareholders was $43.3 million, up from $30.3 million a year ago.

The engineering and consulting firm says net earnings amounted to 41 cents per diluted share for the quarter ended Dec. 31 compared 29 cents per diluted share a year ago.

Revenue totalled $2.04 billion, up from $1.95 billion in the last three months of 2017.
