14:16 ET -- Merck & Co. is one of the most mentioned companies in the U.S. across all news items in the last 12 hours, according to Factiva data. The drugmaker filed a lawsuit challenging the U.S. government's plan to negotiate drug prices, saying it is unconstitutional. The Merck lawsuit alleges Medicare's drug-price-negotiation program, which is part of the Inflation Reduction Act and expected to go into effect starting in 2026, violates First and Fifth Amendment rights.
