With shares trading well off their highs, some investors are asking whether Novavax is undervalued at these levels or if the market has already accounted for the company's future prospects and left little room for upside.

Most Popular Narrative: 49.9% Undervalued

According to the most widely followed narrative, Novavax's calculated fair value stands at $13.11, nearly double the closing price of $6.57. This substantial gap highlights an unusual disconnect between market expectations and consensus projections, setting the stage for high-stakes debate among investors and analysts alike.

The global vaccine market is expected to increase significantly, driven by factors such as aging populations and emerging infectious diseases. This expands Novavax's addressable market and supports long-term revenue growth. Partnership with Sanofi has de-risked commercial execution for Nuvaxovid and opened doors for future milestone and royalty streams, particularly as Sanofi develops and commercializes COVID-influenza combination vaccines. This could meaningfully boost Novavax's recurring revenue and net margins.
