Investis announced today that Gresham Private Equity has backed its management in a £25 million buyout from its existing shareholders and has acquired Morningstar Investor Relations Services.

Morningstar, an investment research and investor news firm, will give Investis access to its extensive network of investors and clients. Its global remit and extensive data and analysis platform will give Investis a solid base from which to expand its investor services.

Investis, a digital corporate communications resource, has focused on investor relations. It recently oversaw the extension of popular U.S. Twitter-like trader-oriented service StockTwits into European markets.

Helen James, who accedes to CEO from managing director in the move, says “We are delighted to welcome the Morningstar IR clients to Investis, and equally excited to be working with a great team of Gresham people who share our vision and culture.”
