On January 30, 2015, the Federal Trade Commission (FTC) announced a settlement of its investigation into Sun Pharmaceutical Industries Ltd.’s (Sun) acquisition of Ranbaxy Laboratories Ltd. (Ranbaxy) from Daiichi Sankyo Co., Ltd. Sun and Ranbaxy are both multinational pharmaceutical companies that produce a range of generic and branded drugs.

In its complaint, the FTC alleges the relevant product market to be “the development, license, manufacture, marketing, distribution, and sale of generic minocycline hydrochloride 50 mg, 75 mg, and 100 mg tablets (‘minocycline tablets’).” Ranbaxy is currently one of only three U.S. suppliers of the relevant doses of minocycline tablets, with Sun being one of a limited number of firms likely to enter the alleged market in the near future. The complaint further alleges that the acquisition would eliminate a potential future competitor and therefore tend to substantially lessen competition by foregoing or delaying Sun’s entry into the relevant market and increase the likelihood that the combined entity would reduce price competition.

To resolve the competitive concern, the FTC is requiring divestiture not only of the minocycline tablets but also a product outside of the alleged relevant market—minocycline capsules. In its aid to public comment, the FTC states that this out-of-market divestiture is necessary to ensure that the divestiture buyer “achieves regulatory approval to qualify a new [active pharmaceutical ingredient] supplier for its minocycline tablets as quickly as Ranbaxy would have.”

Once the FTC or U.S. Department of Justice determines that a competitive problem exists, the agency will seek potential remedies, including divestiture. A cornerstone principle the agencies apply in evaluating a proposed remedy is that the remedy must restore competition to the level that would have existed had the underlying merger or acquisition not proceeded. This case illustrates an application of that principle, where the FTC required the divestiture of the out-of-market assets because, in its view, if those assets were not included the remedy would have left the relevant product market less competitive than it would have been if Sun and Ranbaxy remained independent competitors.

Although not a common outcome, firms considering a transaction involving products subject to regulatory approval should take note of the potential for out-of-market divestitures when assessing a potential deal.
