Faculty

Mr. Morrison advises clients on antitrust M&A, government investigations and litigation. He assists clients in navigating the U.S. merger control regime from a substantive and strategic perspective and in complying with U.S. and global merger control obligations. Mr. Morrison also represents clients in non-merger conduct investigations by the antitrust agencies, including cartel matters, and in antitrust civil litigations.

Ms. Pearl’s practice focuses on antitrust litigation, merger review, and government investigations. She brings a unique perspective from her recent tenure as a trial attorney in the U.S. Department of Justice’s Antitrust Division, where she led complex investigations and litigated high-profile merger cases in the Transportation, Energy & Agriculture Section. Prior to her government service, Ms. Pearl was an associate in the firm’s the Antitrust and Competition Practice Group, where she advised clients on antitrust compliance, merger clearance, and litigation strategy across a broad spectrum of industries, including healthcare, energy, digital platforms, and consumer products. Her work included providing strategic antitrust counsel and representing clients in federal court as well as before the DOJ and the FTC.
Description
On July 19, 2023, the DOJ and the FTC released draft updates to their Merger Guidelines for horizontal and vertical mergers that were a considerable shift in how the DOJ and FTC review mergers. The Merger Guidelines outline the framework the agencies apply when evaluating the competitive impact of mergers and acquisitions. Although not legally binding, these Guidelines are a critical component in the merger enforcement process. Antitrust practitioners refer to them when advising clients and courts regularly cite them in their opinions in merger enforcement cases.
The sweeping changes in the 2023 Guidelines, which were effective on Dec. 13, 2023, were a significant shift in philosophy in how the DOJ and FTC analyze and review mergers. The Guidelines lower the threshold for when a merger is presumptively anticompetitive, provide new frameworks for analyzing less common theories of competitive harm, emphasize the danger of vertical mergers, and give greater consideration to labor markets.
The Guidelines contain 13 points that the agencies use to determine whether they consider a transaction potentially anticompetitive. The first eight Guidelines outline ways by which a transaction may lessen competition; for example, if the transaction significantly increases concentration in a market that is already highly concentrated. The next four clarify how the agencies will approach certain types of transactions or issues in a transaction. The final Guideline is a catchall clarifying that the first 12 Guidelines do not lay out every way in which a transaction may substantially lessen competition.
Listen as our authoritative panel of antitrust experts reviews the Merger Guidelines and provides insight on how the second Trump administration will enforce the Guidelines going forward. The panel will also provide guidance on advising clients on deal activity in light of increased regulatory scrutiny.
