What happened

Shares of Emergent BioSolutions (EBS 5.31%) were tumbling 9.9% lower as of noon EDT on Monday. The big drop came after the company revealed in a filing to the U.S. Securities and Exchange Commission (SEC) that it has agreed not to make any new material at its Bayview facility in Baltimore, Maryland, at the request of the U.S. Food and Drug Administration (FDA). This facility had previously produced COVID-19 vaccines for both AstraZeneca (AZN -0.18%) and Johnson & Johnson (JNJ 0.23%)

So what

Emergent BioSolutions continues to reel from manufacturing issues at its Bayview facility that caused 15 million doses of Johnson & Johnson's COVID-19 vaccine to be discarded. The New York Times reported in late March that the company's staff had inadvertently contaminated a batch of J&J's vaccine with ingredients from AstraZeneca's COVID-19 vaccine.

That highly publicized glitch led Johnson & Johnson to step in and temporarily manage the production of its vaccine at Emergent BioSolutions' Bayview facility. However, today's news means that J&J's efforts were short-lived. 

Every aspect of this story is bad news for Emergent BioSolutions. The company has been regarded as a top contract manufacturer for drugs and vaccines in the past. The repercussions from the COVID-19 vaccine debacle at its Baltimore facility, though, could be long-lasting if customers opt to turn to other contract manufacturers in the future. 

Now what

It remains to be seen how quickly Emergent BioSolutions will be able to move past the dark cloud hovering over it and for the healthcare stock to rebound. One important step will be to get the Bayview facility operational again. The FDA is continuing its inspection of the facility but hasn't yet announced when its review will be complete.
