After such date, WSP will start paying shareholders whose shares have been tendered, which will occur within a 7-day timeframe.

“With the acquisition of Opus, we will continue to deliver on our strategic ambition of enhancing our activities in the Australia/New Zealand region. This combination of two like-minded firms will make us stronger and increase our ability to deliver superior value to our clients, shareholders and our collective employees,” said Alexandre L’Heureux, President and Chief Executive Officer of WSP. “We will now focus on expanding and diversifying our portfolio of expertise, by leveraging Opus’ expertise in the infrastructure (transportation and water) and building sectors as well as in asset management”.
