U.S. Sues to Stop Wilhelmsen From Buying Rival Drew Marine

The FTC said the $400 million proposed deal would reduce competition in the market for marine water treatment chemicals, used in a ship's boiler water and engine cooling water systems.

If Wilhelmsen closed the deal with New Jersey's Drew Marine, the FTC said the company would have 60 percent of the market for marine water treatment chemicals, while its closest competitor would have 5 percent.

"We disagree with the FTC's evaluation and will continue to work towards a positive outcome," Wilhelmsen spokeswoman Benedicte Teigen Gude told Reuters.

She said the deal had been submitted to antitrust enforcers in London and Singapore. It had received approval from Britain, while Singapore's review was ongoing, she said.

The FTC has filed an administrative complaint with an agency judge asking for the deal to be scrapped.

It also authorized staff to request a preliminary injunction in federal court temporarily stopping the deal while the administrative process goes forward.

In most cases, if the agency wins in federal court, the companies cancel their proposed transaction.

The deal has a $200 million termination fee, according to a statement from Wilhelmsen when the transaction was announced in April 2017.
