(The Center Square) – Nine more companies have joined President Donald Trump’s most-favored-nation drug pricing agreement, one of the president’s most highly publicized affordability initiatives to bring down the cost of prescription drugs.

The president signed an executive order in May 2025 directing his administration to work toward securing most-favored-nation pricing with large pharmaceutical manufacturers. Most-favored-nation pricing means a manufacturer has agreed to sell some of its products in the U.S. at no higher a price than the lowest price among its economic peers. Since the order’s signing, the administration has announced deals to that effect with 26 of the largest pharmaceutical manufacturers in the world, as of Monday.
