CI Financial, a Toronto-based global asset and wealth management company, has boosted its U.S. wealth assets to about $21 billion with an agreement to acquire a majority interest in RGT Wealth Advisors, a Dallas-based RIA with about $4.7 billion in assets, according to an announcement from the company today.

The acquisition is the largest U.S. acquisition by assets to date for CI, which has had 10 U.S. wealth management acquisitions this year and 13 overall (including acquisitions by CI affiliated RIAs).

The transaction is expected to close in the fourth quarter, pending regulatory approval and other customary closing conditions, and requisite stock exchange approvals, the announcement said.

RGT offers investment management and wealth management, including financial planning and family office services to high-net-worth individuals, across the U.S.

“RGT, our largest U.S. acquisition by assets to date, is a growing firm with an exceptional team, strong leadership and well-developed expertise attuned to the needs of their clients,” CI CEO Kurt MacAlpine said in a statement. He added that RGT also provides CI with a presence in the important and fast-growing Texas market.

Mark Griege, CEO of RGT, said CI will be a source of extensive experience and resources. “Importantly, we will maintain a meaningful ownership stake in our business and continue to build on our 35-year entrepreneurial legacy,” he said.

Upon completion of all previously announced RIA transactions, including RGT, CI's total U.S. wealth assets are expected to reach about $21 billion, boosting its total North American wealth management assets to about $68 billion, and total assets to about $164 billion. As of October, CI held total assets of $152 billion in the U.S.

The announcement added that CI’s U.S. RIA acquisitions are part of its strategy to globalize the firm and expand its wealth management platform. As part of its strategy, CI will extend the CI Private Wealth brand, which was recently introduced in Canada to represent its high-net-worth and ultra-high-net-worth advisory businesses, to the U.S. in the months ahead, the announcement said.
