1995–2006

From 1995 to 2001, Virtus was a majority-owned indirect subsidiary of Phoenix Life Insurance Co. During this period, the company purchased a majority interest in several boutique investment management companies to establish its multi-manager business model. In addition to Duff & Phelps Investment Management, Virtus’ affiliates during this time included Kayne Anderson Rudnick Investment Management, LLC, Seneca Capital Management, and Zweig Advisers LLC, which was founded by legendary Wall Street investor Martin Zweig.

On January 11, 2001, a subsidiary of Phoenix acquired the outstanding shares of Phoenix Investment Partners not already owned, and the company became an indirect wholly owned subsidiary of Phoenix.

In May 2005, Phoenix Investment Partners acquired the remaining minority interest in Seneca Capital Management and in September of that year acquired the remaining minority interest in Kayne Anderson Rudnick, thereby increasing ownership of both companies to 100%. In May 2006, Phoenix Investment Partners adopted the Harris Insight Funds from Harris Investment Management, Inc.

2006–2009

In February 2008, Phoenix announced it would spin off Phoenix Investment Partners as an independent asset management company through a pro rata dividend of Phoenix Investment Partners' common stock to Phoenix's shareholders.^[1] On October 30, 2008, Harris Bankcorp Inc., a U.S. subsidiary of Bank of Montreal, announced it would acquire $45 million in convertible preferred stock, representing a 23 percent equity position in Virtus.^[2]

Virtus became an independent publicly traded company on December 31, 2008, upon completion of its spin-off from Phoenix. The first day of trading of VRTS was January 2, 2009, and company officials rang the opening bell at NASDAQ Market Site on January 5, 2009.^[3]

2010–present

The years 2011 through 2018 were a period of expansion for Virtus as it established or acquired several affiliated managers, beginning in June 2011, when it established Newfleet Asset Management as a fixed income affiliate with approximately $5.2 billion of assets under management. David L. Albrycht, formerly executive managing director of Goodwin Capital Advisors, an investment management company that previously was a subsidiary of Virtus, became chief investment officer of Newfleet.^[4]

In October 2012, Virtus completed the acquisition of Rampart Investment Management, a registered investment adviser specializing in options strategies. In 2013, the company established a Dublin-based UCITS, and in 2015 acquired a majority interest in ETF Issuer Solutions (ETFis), a New York City-based company that operates a platform for listing, operating, and distributing exchange-traded funds. It was renamed Virtus ETF Solutions.

In December 2016, Virtus agreed to acquire multi-boutique asset manager RidgeWorth Investments from private equity firm Lightyear Capital and Ridgeworth's employees for $472 million. That transaction, which was completed in June 2017, added approximately $40 billion in assets managed by Ridgeworth's three wholly owned affiliates, Ceredex Value Advisors, Seix Investment Advisors, and Silvant Capital Management.^[5]

Virtus completed a majority investment in Sustainable Growth Advisers (SGA), an investment manager headquartered in Stamford, Connecticut that specializes in high-conviction U.S. and global growth equity portfolios, in July 2018.^[6]
