ONEX Onex Corporation

Gluskin Sheff + Associates Inc. (“Gluskin Sheff”), the wealth management platform of Onex Corporation (“Onex”) (TSX: ONEX), today announced the launch of the Onex Partners Private Equity Solution 2022 (“the Fund”), a private equity strategy that seeks to generate compelling returns for Canadian high-net-worth investors, with an emphasis on capital preservation.

For the first time, Canadian accredited investors can access Onex’ private equity platform through Gluskin Sheff to uncover an investment opportunity previously unavailable to the retail accredited investor market. The Fund’s structure represents a unique offering for eligible investors who seek to benefit from:

• Higher return opportunities relative to traditional public markets
• Diversification to offset public market exposure
• Less volatility compared to public markets
• Thoughtful ESG analysis included in investment process
• A longer-term investment horizon

“As the investment landscape continues to shift and evolve, we have a leading edge as part of Onex. Through our partnership, we are enabled to address the growing retail demand for alternative products and offer our clients exclusive access to customized private capital solutions typically reserved for institutional investors,” said Dave Kelly, Head of Gluskin Sheff. “Managed by a Canadian industry leader with a long-term record of success, the Onex Partners Private Equity Solution 2022 provides Canadian individual investors with a sophisticated investment strategy to further diversify their portfolios, while gaining primary access to a challenging asset class.”

The Fund aims to provide enduring capital appreciation primarily through targeting opportunities in four industry verticals with demonstrated returns through economic cycles, including industrials, business services and software, healthcare and financial services. The Fund seeks to invest in businesses with a resilient value proposition where the Onex investment team has a differentiated perspective due to their industry experience and knowledge.

“For almost two decades, Onex’ flagship private equity platform, Onex Partners, has been creating value for our investors by placing an emphasis on capital preservation and achieving strong absolute growth through market cycles,” said Bobby Le Blanc, President of Onex and head of Onex Partners. “With our partners at Gluskin Sheff, we believe we are well positioned to help strengthen Canadian individual investors’ portfolios by providing them access to institutional-quality private equity solutions.”

Formed by Onex in 2003, Onex Partners is Onex’ private equity platform focused on investing in mid- to large-cap companies. This platform is a continuation of Onex’ original investment strategy dating back to 1984. Onex Partners principally targets investment opportunities in the United States, Canada and Europe that require $200 million or more of initial equity capital.
