Investors shouldn't dwell on what analysts think. Instead, focus on the business prospects for Emergent BioSolutions. And those prospects continue to look quite good.

The company expects to deliver revenue in full-year 2021 of between $1.95 billion and $2.05 billion with adjusted earnings between $475 million and $525 million. The midpoint of the revenue range reflects year-over-year growth of nearly 29%. The midpoint of the adjusted earnings range reflects growth of nearly 18%.

Now what

One potential catalyst for the healthcare stock could be on the way soon. Johnson & Johnson could obtain U.S. Emergency Use Authorization (EUA) for its COVID-19 vaccine by the end of February. Emergent BioSolutions has a contract with J&J to manufacture its vaccine.
