HOUSTON, TX, September 13, 2011 - RigNet, Inc. (NASDAQ: RNET), today announced it has been added to the Russell 3000® Index and Russell 2000® Index when Russell Investments reconstituted its comprehensive set of U.S. and global equity indexes on June 24, 2011.

Russell indexes are widely used by investment managers and institutional investors for both index funds and as benchmarks for passive and active investment strategies. The Company will hold its membership until Russell reconstitutes its indexes in June 2012.

"We are pleased to be added to the Russell 2000, which reflects our continued positive momentum and efforts to increase shareholder value," said Mark Slaughter, RigNet's CEO and president.
