Newman Ferrara LLP is investigating potential claims against the board of directors of PetroLogistics LP (“PetroLogistics”) (NYSE:PDH) concerning the proposed sale of PetroLogistics to Flint Hills Resources, LLC, a subsidiary of Koch Industries, Inc.

PetroLogistics has entered into an agreement and plan of merger to be acquired by Flint Hills pursuant to which, PetroLogistics’ minority stockholders will receive only $14.00 in cash per common unit owned. However, PetroLogistics stock has traded at above the $14.00 per unit offer price as recently as April 29, 2014, when it traded at $14.14 per unit. The offer price is also below the 52-week trading high of PetroLogistics stock of $14.28 per unit. Flint Hills will also acquire all of the membership interests in PetroLogistics GP for no additional consideration.

In addition, a group of holders consisting of PetroLogistics’ Executive Chairman David Lumpkins, PetroLogistics’ CEO and President Nathan Ticatch, Lindsay Goldberg LLC, and York Capital Management, who collectively own 73% of PetroLogistics stock, will receive $12.00 in cash for each unit owned. These unit holders have already given written consent approving the proposed deal and have entered into support agreements with Flint Hills.

Newman Ferrara’s investigation concerns whether PetroLogistics’ Board of Directors has breached its fiduciary duties to act in the best interests of PetroLogistics’ minority stockholders. The investigation focuses on the potential unfairness of the consideration being provided to PetroLogistics’ stockholders and the process by which PetroLogistics’ Board of Directors considered and approved the proposed deal.
