Novavax (NVAX): Assessing Valuation After Japan Vaccine Approval and Takeda Milestone Payment

Novavax (NVAX) has been in the spotlight after its COVID-19 vaccine, Nuvaxovid, secured regulatory approval in Japan. This approval unlocked a milestone payment from partner Takeda and set up Novavax to receive royalties from upcoming Nuvaxovid sales during the vaccination season. What makes this event stand out is the improved collaboration agreement between the two companies, aiming to boost Novavax's presence and commercial opportunity in Japan. Japan is an important market for any global vaccine player.

This fresh momentum comes after a challenging period for Novavax, with the share price down 34% over the past year and dropping 11% in the past month alone. However, the stock has bounced back 36% over the past 3 months, suggesting that recent news, including upgrades to its partnership with Takeda and milestones like the one just announced, may be shifting sentiment. Other recent developments, like presentations at major healthcare conferences, have added to the company’s visibility, but it is clear that business fundamentals are in the spotlight.

After a volatile stretch and this milestone payment, is Novavax now trading at a discount that undervalues its future, or is the market already betting on more growth ahead?

Most Popular Narrative: 31.5% Undervalued

According to the most widely followed narrative, Novavax is considered significantly undervalued, with its fair value set well above the current share price. This perspective argues that, despite sharp projected declines in revenue and earnings, future opportunities and partnerships may not be fully appreciated by the market.

"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, which could meaningfully boost Novavax's recurring revenue and net margins."

Wondering what justifies such a bullish target? There is one controversial set of numbers behind this model, driven by bold assumptions about future earnings and strategic collaborations. Will shrinking profit margins and declining revenues really deliver on this high valuation? Get the full picture by dissecting the narrative’s core financial logic and see for yourself what analysts are betting on.

Result: Fair Value of $12.50 (UNDERVALUED)
