Professional services firm Marsh agreed to buy Wilshire from Motive Partners and CC Capital, adding an investment consulting, solutions and analytics business serving institutional investors and financial intermediaries.
As of June 30, Wilshire had $221 billion in assets under management (AUM) and more than $1.6 trillion in assets under advisement, including the AUM, according to Marsh.
The deal is expected to close in the first quarter of 2027. Motive Partners and CC Capital invested in Wilshire in 2021.
Marsh said the purchase would extend its investments business into advisor‑led wealth management. Wilshire’s employees in the U.S., Europe and Asia would join Marsh when the transaction closes.
“The acquisition of Wilshire is an important step in growing Marsh’s investments business and strengthening our connection to the financial advisor ecosystem,” John Doyle, President and CEO of Marsh, said in a press release. “By combining Wilshire’s capabilities with our global reach, open architecture, and expertise across public and private markets, we can help clients make better decisions and build resilient portfolios in an increasingly complex investment environment.”

“Over the past decade, we’ve built a comprehensive platform serving institutional investors and wealth clients with advice, products, and solutions,” Pat Tomlinson, President and CEO of Marsh People and Investments; Vice Chair of Marsh; and CEO of Marsh US and Canada, said in the release. “Wilshire will expand our scale and capabilities, particularly in alternatives, model portfolios, and data and analytics, strengthening our platform for wealth advisors and asset managers.”

Jason Schwarz, CEO of Wilshire, said in the release, “Wilshire has spent more than five decades building innovative, institutional‑quality investment capabilities and delivering them to clients across institutional, wealth, and retirement markets. Now is the time to join with Marsh, and through its global reach and resources, extend our platform, broaden our capabilities, and serve clients across the investment value chain.”
Marsh also completed its acquisition of AltamarCAM, a private markets asset manager and solutions provider, on Nov. 4.
