Waste Management Inc. has agreed to buy medical waste company Stericycle at an enterprise value of about $7.2 billion, inclusive of approximately $1.4 billion of debt, the companies said in a statement Monday.

Vinson & Elkins LLP and Baker Botts LLP are representing Waste Management, while Latham & Watkins LLP is representing Illinois-based Stericycle on the deal, which the companies said has been approved by both of their boards of directors and is expected to close in the fourth quarter of this year.

The $62 per share cash deal represents a 24% premium to Stericycle's 60-day volume weighted average price as of May 23, the last trading day before a media report disclosed a potential sale, the statement said.

Stericycle's stock was up about 15% Monday morning, at $59.25 per share, after closing at $51.54 per share Friday.

Houston-based Waste Management noted that Stericycle's medical waste and secure information destruction solutions are positioned to benefit from the positive growth outlook for healthcare services in North America.

"We are committed to maximizing value for all our stakeholders by providing a comprehensive suite of environmental solutions to the market," Jim Fish, president and CEO of Waste Management, said in Monday's statement. "The acquisition of Stericycle ... broadens the scope of our service offerings, bringing together the leader in solid waste and a premier company in regulated medical waste services."

Cindy J. Miller, Stericycle's president and CEO, said that the deal "creates significant value for shareholders, unlocks new opportunities to deliver diversified services to customers, and supports investment in the growth and development of our team members."

"As customers seek to manage a greater volume and variety of materials in a safe, responsible, and sustainable way, Stericycle's knowledge and expertise in regulated medical waste and secure information destruction are compelling additions to WM's broad portfolio of environmental solutions," she added.
