Iron Mountain's profit slips slightly

Data storage and protection company Iron Mountain Inc. of Boston said today that its first-quarter profit slipped 3.5 percent as higher interest expense offset rising revenue.

Net income for the three months ended March 31 fell to $33.5 million from $34.7 million.

Net interest expense climbed 19 percent to $60 million.

Revenue increased 18 percent to $749.4 million from $632.5 million.

Sales rose in the company's North American physical, international physical, and worldwide digital business segments, and benefited from the weaker dollar. (AP)
