AssetMark Financial announced its plan to acquire Efficient Advisors, an asset management platform overseeing $3 billion in client assets, from Fiduciary Services Group (FSG). The acquisition strengthens AssetMark’s position within the registered investment advisor (RIA) channel and supports its long-term strategy to expand its wealth management capabilities through both organic and strategic growth.
The transaction provides Efficient Advisors with access to AssetMark’s comprehensive wealth management platform, which includes advanced advisor technology, tailored consulting services, and a broad selection of investment strategists. AssetMark will establish a network of RIAs and advisors recognized for their deep client relationships, enabling the company to expand its reach while providing advisors with the necessary tools and support to enhance growth and client service.
This acquisition builds on AssetMark’s continued momentum in the RIA space. It follows its recent strategic alliance with Morningstar Wealth, as well as the acquisition of the Morningstar Wealth Turnkey Asset Management Platform. It represents the company’s eighth announced acquisition since 2014. The deal is expected to close in the fourth quarter of 2025, subject to customary conditions and receipt of all necessary regulatory approvals.
Advisors/counsel: PricewaterhouseCoopers International Limited served as the financial advisor, and Kirkland & Ellis provided legal counsel to AssetMark. DLA Piper advised Fiduciary Services Group.
