The New Antitrust Frontier: How the “Most-Favored Nation” (MFN) Executive Order Targets Drug Pricing Power

In a marked shift toward competition-focused healthcare policy, the latest Executive Order on drug pricing reflects the Administration’s expanding use of antitrust tools to address high pharmaceutical costs. Framed around the “most-favored-nation” principle, this initiative is more than a pricing measure—it signals a broader regulatory agenda that targets market power and pricing disparities long shielded from traditional enforcement. Here’s what companies across the healthcare sector need to know.

DOJ Secures First Jury Conviction in Criminal Wage-Fixing Case in Nevada

In an historic jury verdict on April 14, 2025, the U.S. Department of Justice’s Antitrust Division secured its first-ever jury conviction for criminal wage-fixing in violation of Section 1 of the Sherman Act.  For several years, the DOJ Antitrust Division had suffered a string of setbacks—with judges and juries alike—in its effort to criminally prosecute wage-fixing and “no poach” agreements between competitors in the labor market.  But a federal jury in Las Vegas, Nevada, reversed that trend by convicting Eduardo Lopez for his involvement in a three-year conspiracy to fix the wages of home healthcare nurses in the Las Vegas area, among other crimes.

Trump 2.0: Non-Merger Antitrust Enforcement Under Trump’s Second Term

A second Trump administration brings some uncertainty about the trajectory of non-merger antitrust enforcement. Under the Biden administration, the Federal Trade Commission (FTC) and the Antitrust Division of the Department of Justice (DOJ) took an aggressive approach to antitrust enforcement across several industries and were particularly hostile to mergers and acquisitions. President Trump’s nominees to lead the antitrust agencies signal that the new administration is likely to continue current levels of vigorous antitrust enforcement—particularly in Big Tech and other hot-button industries—but will likely relax M&A enforcement and return to more predictable and traditional tools and theories of harm.

Gun-Jumping Charges Remind Dealmakers to Operate Independently Before Closing

In early August, the U.S. Department of Justice (DOJ) entered a consent decree with Legends Hospitality Parent Holdings, LLC (“Legends”) to resolve gun-jumping allegations that Legends improperly exerted operational control over ASM Global, Inc. (ASM) while its HSR filing for its acquisition of ASM remained pending. Although the DOJ allowed the transaction to close, Legends agreed to pay $3.5 million and be subject to seven years of DOJ oversight to resolve the allegations. This action by the DOJ provides a reminder to buyers and sellers of the need to continue operating independently after a deal is signed until closing even when the deal does not present significant antitrust concerns.

FTC and DOJ Propose Drastic Overhaul of HSR Requirements: New Form, New Frontier

On June 27, 2023, the Federal Trade Commission (FTC) announced that it will issue a 132-page Notice of Proposed Rulemaking drafted in concurrence with the U.S. Department of Justice (DOJ) that, if implemented, would bring sweeping changes to the U.S. merger review process. The proposed changes would require merging parties reporting transactions under the Hart-Scott-Rodino Act (HSR) to collect and submit to the FTC and DOJ significantly more information than is currently reported in the HSR form, likely significantly lengthening the time and expense associated with reporting transactions under the HSR Act. Indeed, the FTC’s own estimate is that the number of hours required to prepare an average HSR filing will increase nearly four-fold from 37 to 144 hours. Although the FTC states in its press release that the purpose of the proposed changes is to improve the efficiency and effectiveness of merger reviews, the additional burden on merging parties will be substantial.
