Divestopedia explains Institutional Investor
An institutional investor is a non-bank organization that trades in large enough quantities to qualify for preferential treatment. They have to deal with fewer protective regulations as they are considered to be more knowledgeable about market operations and, hence, are better able to protect themselves. They act as highly specialized investors on behalf of others and supply capital to firms seeking to raise financing, or to those that are in dire straits. Economies of scale increase the returns on their investments and lower the cost of capital for entrepreneurs. Furthermore, they can yield significant influence in the managements of corporations as they are usually entitled to exercise the voting rights in a company.

They allocate their monitoring efforts to a firm on the relative importance of the firm's stock and portfolio. The probability of deal completion increases in the holdings of institutional investors in the target firm. They result in higher final premiums and lower acquirer's returns as well.
