FTC ALJ ordered Polypore to sell the stake in Microporous to an FTC-approved buyer within six months of the final order. Polypore had acquired the battery maker just over two years ago, and the FTC at that time sought unsuccessfully to block the deal. The ALJ found that the FTC demonstrated that the merger had reduced competition in four distinct batter markets. This case may be evidence of a growing desire at the enforcement agencies to attack consummated mergers that are lessening competition.
