This session will consider how to manage antitrust considerations in transactions occurring in markets facing significant contraction or expansion in output. As the energy transition occurs, some market segments are left with the prospects of reduced output while others are seeing dramatic growth. Mergers or collaborations are frequent responses to try to match supply and demand in a particular geography, but antitrust considerations, if not addressed early, can pose significant hurdles to either reducing capacity to match reduced demand or sharing capacity in rapidly expanding markets. We will consider strategies to best position transactions in light of such concerns.
