Private Equity Firms

Private equity firms provide investment capital and investment management services. Such firms raise investment capital from individuals and institutional investors, such as pension funds, to fund equity investments in companies either through direct purchase of an equity stake in private companies or through leveraged buyouts, or LBO, of publicly traded companies. Private equity firms often obtain an equity interest by providing venture capital, sometimes in partnership with other private equity firms.

Once it acquires a controlling interest in a company, a private equity firm then directs the management of the acquired company with the ultimate goal of substantially increasing the company’s value so it can be sold for a profit. Private equity firms often specialize in investments in particular industries or market sectors. A private equity firm’s portfolio is composed of companies it has acquired or in which it holds a substantial equity interest. The investment horizon for most private equity firm investments is five to 10 years.
