Case
FTC v. Wilhelm Wilhelmsen, et al.
An Analysis Group team assisted the Federal Trade Commission (FTC) in its successful effort to block Wilhelmsen Maritime Services AS's proposed $400 million acquisition of Drew Marine Group Inc.
In February, the FTC sought a temporary restraining order and a preliminary injunction in federal court to block the deal from closing while the agency conducted an administrative trial to determine its legality. The FTC contended that the acquisition would diminish competition – with the combined entity commanding 85% of the market share for marine water treatment chemicals – and effectively create the only truly global supplier of these products.
Supporting the FTC was a team of economists from Analysis Group, led by Managing Principals Dov Rothman and Aaron Yeater, with support from Vice Presidents Philipp Tillmann and Alex Robinson. Dr. Rothman testified that the cost efficiencies projected by Wilhelmsen could not be verified, and that many of the projected cost efficiencies would not be merger-specific. He also addressed the extent to which any verifiable and merger-specific cost efficiencies would have affected the merged firm's pricing incentives.
On July 21, following a three-week bench trial, US District Judge Tanya S. Chutkan issued a sealed opinion granting the FTC's motion for an injunction. Following the decision, Wilhelmsen Maritime announced that it will abandon the transaction and pay a termination fee of $20 million to Drew Marine.
