David Ackert will join Montreal-based engineer WSP Global Inc. as CEO of its WSP Canada Inc. unit when the parent firm completes its stock and cash purchase of Focus Group Holding Inc., a 1,700-person design and geomatics company in Edmonton, Alberta. The $366-million deal, announced on March 12, is set to close within one month, said publicly traded WSP. Ackert is now president and CEO of Focus Group Holdings, which specializes in the oil-and-gas sector and has $280 million in revenue, says a published report in Canada. It "did well" when owned by a private equity fund, says Scott Kolbrenner of investment banker Houlihan Lokey.

Ackert also will become director of WSP's oil-and-gas network, while Marc Rivard will continue as president and COO of WSP Canada Inc. The transaction will add 1,700 employees to WSP, for a workforce total of 16,700, the firm said; about 6,700 will be in Canada. WSP Global CEO Pierre Shoiry said the acquisition will boost the parent firm's presence in western Canada and its sector expertise in upstream, oil sands, midstream and LNG export infrastructure development. Shoiry had been CEO of Montreal-based Genivar Inc., which bought WSP in 2012 but now uses its name for the global firm. It has made 80 acquisitions since he became CEO in 1995.
