ICON plc (NASDAQ: ICLR) announced that its wholly-owned subsidiary, ICON Investments Six Designated Activity Company, intends to offer one or more series of senior notes in a private placement with registration rights, subject to market and other conditions.

The notes will be guaranteed on a senior unsecured basis by ICON.
