ONEX Onex Corporation

Earlier today, Onex Corporation (TSX: ONEX) announced an agreement with RBC Wealth Management Canada (“RBC WMC”) to expand distribution of Onex investment products through RBC WMC. All advisor team employees of Gluskin Sheff will be offered employment with RBC WMC. Consequently, Gluskin Sheff intends to wind down its wealth management and wealth planning operations not transferred to RBC WMC.

Onex will continue to focus on the creation of highly differentiated alternative investment products, including those to be made available to RBC WMC advisors and clients.

“Gluskin Sheff has a long and successful track record of delivering innovation, results and high client satisfaction in the Canadian wealth management sector. We are proud of our association with the team and are grateful for their contributions. I am confident in the value they will continue to drive for their clients,” said Bobby Le Blanc, President of Onex.

“As we have indicated previously, the private wealth channel remains an area of significant potential growth for Onex. This agreement with one of Canada’s largest wealth management platforms represents an attractive near- and long-term opportunity to diversify and expand our reach among private investors,” added Mr. Le Blanc.

Onex expects to recognize a non-cash impairment of goodwill and intangibles and a restructuring charge in connection with the transfer and wind down of Gluskin Sheff’s residual operations. The wind down will be effected in accordance with applicable regulatory obligations, including any required notice to or approval by regulators. Onex expects to provide an update on the wind down and its financial impact with its first quarter earnings results in May 2023.
