Brooklyn-based Victory Capital Holdings, the former investment management unit of KeyCorp, has filed with the SEC to raise up to $100 million in an initial public stock offering. The Brooklyn-based company was bought from Key in 2013 by PE firm Crestview Partners and key management for $246 million. Since then, Victory has remade itself into a $59 billion operation with an unusual business model that centralizes distribution, marketing and operations infrastructure for a series of acquired investment brands that it refers to as “Franchises.” “Our Franchises are operationally integrated, but are separately branded and make investment decisions independently from one another within guidelines established by their respective investment mandates,” the company said in its SEC filing. “Our integrated multi-boutique model creates a supportive environment in which our investment professionals, largely unencumbered by administrative and operational responsibilities, can focus on their pursuit of investment excellence.” In the same filing, the company said it sees “significant” opportunity for more acquisitions. It previously acquired Munder Capital Management, Compass Efficient Model Portfolios and RS Investments. Victory Capital, which dates back to 1894, plans to list on the Nasdaq under the symbol VCTR. J.P. Morgan, BofA Merrill Lynch, Morgan Stanley, Barclays, Goldman Sachs and RBC Capital Markets are lead underwriters on the deal. No pricing terms were disclosed. Crestview will maintain majority voting control of Victory Capital following the offering.
