So what

AbCellera Biologics provides antigen discovery and engineering services for pharmaceutical companies. Sales and earnings have soared over the last year thanks to royalties it received for discovering Eli Lilly's  bamlanivimab antibody COVID-19 treatment. However, the Emergency Use Authorization (EUA) for bamlanivimab was withdrawn in June, and investors have been worried that revenue and profits would tumble and take a long time to recover. 

AbCellera generates revenue from R&D and milestones, but it gets the majority of its sales from royalties. Comments from management in the company's second-quarter call suggested that the business could soon enjoy another royalties windfall. 

While EUA has been withdrawn for bamlanivimab, the company also has another antibody-based treatment in in phase 2 clinical testing with Lilly. Early testing suggests that the bebtelovimab antibody is a potent antibody capable of effectively binding to spike proteins, and it could provide a significant new revenue source if the treatment makes it to market. Even better, things appear to be looking up on the bamlanivimab front. 

Now what

AbCellera Biologics stock has continued to gain ground early in September's trading. The company's share price is up roughly 11.7% in the month so far.

The stock is gaining ground in response to federal officials paving the way for bamlanivimab to start being used as a COVID-19 treatment again. Lilly's combination of the bamlanivimab and etesevimab antibodies has demonstrated efficacy in treating delta variant cases, and it's set to be shipped to over 20 states.

AbCellera Biologics has a market capitalization of roughly $5.2 billion and remains a somewhat risky investment. However, its ability to quickly identify the bamlanivimab antibody reflects well on the value of the company's platform, and the stock could serve up big wins for risk-tolerant investors.
