Owens & Minor, Inc. Provides Updated Financial Guidance for 2012

Following the company’s 2Q 2012 financial results conference call,

OMI management updated guidance for 2012

RICHMOND, VA….BUSINESSWIRE…Owens & Minor, Inc. (NYSE-OMI) today updated its financial outlook for 2012, following its second quarter 2012 financial results conference call, conducted on July 24, 2012, by company management.

“As we contemplated our outlook for the remainder of 2012, we recognize that certain factors have come into play since we first issued our guidance for 2012 in December of 2011,” said James L. Bierman, chief operating officer of Owens & Minor. “These factors point to a slightly slower growth and profitability year than we had originally planned, and we now believe that our revenue growth for the full year of 2012 will be below the original annual revenue guidance of 3% to 5% for our U.S.-based operations,” said Bierman.

“Adding further complexity to our outlook for the remainder of 2012 is our pending acquisition of the Movianto Group from Celesio AG. Our 2012 revenues will be positively impacted by the acquisition; the actual amount will be dependent on the date of the actual closing of the transaction in 2012,” said Bierman. Movianto’s 2011 revenues were in excess of €300 million.

“Dilution of earnings per share related to the transaction is targeted to be between $0.10 and $0.15 per share, much of it transaction-related costs. As for our revised guidance for net income per diluted share for the year, we are targeting a range of $2.04 to $1.98, excluding the dilution associated with the pending Movianto transaction.”
