Novavax (NVAX): Exploring Valuation After Analyst Upgrades and Renewed Investor Interest

Simply Wall St
Novavax (NVAX) is catching the attention of many investors lately, and it is not just because of another biotech headline. The spark this time comes from a wave of analyst upgrades, with recent earnings estimates being revised higher. These shifts are fueling optimism around Novavax's growth story, leaving investors wondering if the momentum can last and whether there is more upside ahead. Shares have seen a jump of over 14% in the past month, after spending much of the year treading water. That momentum stands out, especially as Novavax’s long-term performance has struggled, with the stock still down substantially over the past year and longer periods. The analyst activity, combined with Novavax continuing to show a solid momentum profile, suggests that risk perceptions may be shifting and sentiment could be improving. With the stock finally on the move after months of little change, the key question is whether this is the start of a sustained run or if the market is already pricing in what comes next. Is Novavax undervalued even after these gains, or is further growth already factored into its price?

Most Popular Narrative: 31.6% Undervalued

According to the most widely followed narrative, Novavax shares are undervalued by a sizeable margin, based on analysts’ financial projections and discount rates.

The successful commercialization of the R21 Matrix-M malaria vaccine, already deployed in 12 African countries with over 20 million doses sold, showcases the potential for expanding sales in underserved infectious disease markets. This could increase both revenues and operating leverage through economies of scale.

Wondering what kind of bold assumptions power a fair value that is so far above today's market price? The narrative hinges on dramatic forecast changes for profit margins and future earnings, with a valuation model that even beats sector averages. Eager to see which numbers unlock that optimism? The drivers hiding under the surface just might surprise you.

Result: Fair Value of $12.50 (UNDERVALUED)
