The federal administration is pursuing executive and regulatory actions directing HHS to pursue most favored nation (MFN) pricing targets for prescription drugs and to evaluate other potential reforms including, for example, an executive order tasking the Center for Medicare and Medicaid Innovation (CMMI) to consider new payment and healthcare models to limit drug spending, and promote MFN drug pricing, among other directives. For example, on December 23, 2025, CMS issued proposed regulations to establish, under CMMI, two mandatory MFN demonstration models under Medicare Parts B and D, respectively. If these rules or other MFN pricing rules are finalized, they are likely to reduce prices of at least some drugs in the United States, if they are also sold in comparator countries. Even if a company does not market drugs in such countries, the company could be indirectly affected if its drugs compete with drugs whose prices were reduced as a result of MFN pricing initiatives.
