Iron Mountain Incorporated Announces 200% Increase to Quarterly Dividend

"The increase in Iron Mountain's dividend is the result of our disciplined management approach and the success we've had as an organization driving higher profitability and strong cash flows," said Bob Brennan, president and CEO. "The strength of our balance sheet and our cash flows positions us to increase our dividend and allows our stockholders to further participate in the Company's success. The increased dividend reflects the Board's confidence in our ability to grow our business profitably while delivering strong, sustainable returns for our investors."

The declaration and payment of future quarterly dividends are in the discretion of the board of directors based on their determination that doing so is in the best interest of Iron Mountain stockholders.

In a separate announcement, the Company announced that it intends to call for redemption the remaining $231 million aggregate principal amount outstanding of its 7-3/4% Senior Subordinated Notes due 2015.
