(Adds comment from spokesman for Canadian industry minister)
March 28 Sterigenics, a sterilization services provider owned by private equity firm GTCR LLC, has reached a deal to buy Canadian medical isotopes supplier Nordion Inc for $727 million.
The offer of $11.75 per share represents a 12 percent premium to Nordion's closing price on the New York Stock Exchange on Thursday, the companies said.
"That's basically what our fair value was (for Nordion), so we think they're getting a fair price," Morningstar analyst David Krempa said.
Nordion's U.S.-listed stock trades at 8.3 times forward earnings, a slight discount to the sector median of 11.4.
Nordion is one of the world's leading producers of molybdenum-99, an isotope used in medical imaging, and the company depends on raw material from an ageing Atomic Energy of Canada Ltd (AECL) facility in Chalk River, Ontario.
A medical isotope is a radioactive substance used mainly to diagnose illness.
The Canadian government said earlier on Friday it would remove the 25-percent foreign investment cap on Nordion in cases that are deemed to be of net benefit to Canada, under legislation introduced on Friday.
Industry Minister James Moore would have to approve the purchase for it to go forward. Asked if the minister would consider its takeover to be of net benefit to Canada, Moore spokesman Jake Enwright noted the government has a procedure for dealing with such offers.
"Our government's balanced approach ensures that foreign investment transactions are reviewed on their merits based on the long-term interests of the Canadian economy," he said in an e-mail.
Ottawa-based Nordion hired advisers Jefferies & Co in early 2013 to examine options for its future, and the sale to Sterigenics would mark the completion of that review, said Nordion Chief Executive Officer Steve West.
Deerfield, Illinois-based Sterigenics provides outsourced contract sterilization services to the medical, pharmaceuticals, food safety and other industries.
"Our focus is to ensure a stable long-term source of Cobalt-60 that will maintain customer confidence in the future availability and growth of gamma sterilization," said Michael Mulhern, chief executive of Sterigenics.
Cobalt-60 emits high energy gamma rays that are used to eliminate harmful organisms in a variety of products.
Upon closing of the deal, expected in the second half of 2014, Nordion will operate as a standalone company.
Stikeman Elliott LLP and Skadden, Arps, Slate, Meagher & Flom LLP were Nordion's legal counsel. Gowling Lafleur Henderson LLP and Kirkland & Ellis LLP were counsel to Sterigenics.
Nordion's shares have risen as much as 23 percent in the last three months to Friday's close of $10.41 on the New York Stock Exchange.
