Cogent Systems [COGT] says the value of its contract with the Post Office Limited in the United Kingdom is worth $60 million over five years, making it potentially the largest single international win in the company’s history. The company previously disclosed its selection for the award on its most recent earnings call. “This is an important win that will help the company’s growth over the next several years,” says Morgan Keegan analyst Brian Ruttenbur. He believes Cogent will see some revenue from the contract this year, which will be upside to the company’s earlier conservative guidance.
