Amgen Inc on Tuesday said its fourth-quarter revenue fell slightly as a 4% increase in sales of its own drugs was offset by lower revenue from its deal to manufacture COVID-19 antibody treatments for Eli Lilly and Co. Amgen reported revenue of $6.84 billion for the quarter, down from $6.85 billion a year ago, but ahead of analysts’ estimates of $6.77 billion, according to Refinitiv data.
