Nielsen Holdings NV said Monday that private equity firms and some other stockholders plan to sell 25 million shares, as long-time investors pare their holdings.
A group of six firms, including The Blackstone Group, Kohlberg Kravis Roberts & Co. and Thomas H. Lee Partners, bought Nielsen in 2006 for $9.7 billion. They took the TV ratings and consumer research company public in a January 2011 IPO that raised about $1.9 billion.
The company said Monday that it's not selling shares and won't receive any of the proceeds.
Nielsen makes its money by selling data about what people are buying in stores and watching on television. It is known for its weekly rankings of TV's most watched shows, a breakdown that helps determine the advertising prices charged by broadcasters and cable channels.
Last month Nielsen, which is based in New York and the Netherlands, reported that its fourth-quarter net income rose, benefiting from growth in developing markets, less money spent on interest payments and fewer charges related to its initial public offering in January 2011.
