3M Co. dropped its $550 million takeover of Avery Dennison Corp.'s office-products unit after the Justice Department said it would sue if the companies didn't abandon the transaction, the government said.
The Justice Department said in an e-mailed statement that its investigation found that 3M and Avery have dominated adjacent spaces in the office products business for many years, with Avery making labels and 3M selling sticky notes under its Post-it brand.
The merger would have given Maplewood-based 3M more than 80 percent of the U.S. market for labels and sticky notes, according to the statement.
"We welcome the companies' decision to abandon this deal, which raised competitive concerns in the sale of labels and sticky notes," Joseph Wayland, acting assistant attorney general for the Antitrust Division, said in a statement. "As a result of the abandonment of this transaction, American customers will continue to receive the benefits of competition including lower prices and greater innovation in these basic office supplies."
3M, which announced the acquisition more than eight months ago, had planned to complete the purchase in the second half of this year.
Donna Fleming Runyon, a spokeswoman for 3M, and David Frail, a spokesman for Avery, didn't immediately return phone and e-mail messages seeking comment. Avery is based in Pasadena, Calif.
The deal would have combined the two largest labelmakers in the world, according to Deane Dray, an analyst at Citigroup Inc. in New York City.
The agreement would have married Avery Dennison's Hi-Liters, Marks-A-Lot pens, labels and other office products with some of 3M's best-known brands, including Scotch tape and Post-it Notes.
