Upcoming Webinar –Life Sciences and the FTC in the Trump Administration: Implications and Opportunities for Dealmakers
January 21, 2025, 1–2 pm ET

The return of Donald Trump to the White House has raised the question of whether the past four years of pronounced hostility from federal antitrust enforcement agencies to M&A and the life sciences industry is likely to continue. In other words, are we likely to look at the Biden FTC as an unpleasant detour or a horrifying on-ramp with respect to future antitrust enforcement? At the same time, the announcement of new Merger Guidelines, the advent of new HSR rules, and recent lawsuits and opinions may have significant implications for planning and executing deals in this new environment. During this webinar, three leading antitrust practitioners with involvement in some of the most important life sciences M&A matters will describe what all of this means for dealmaking.
