Novavax (NVAX) Valuation Check as FDA Scrutiny Rises and Activist Pushes for Possible Sale

Novavax (NVAX) is back in the spotlight after a controversial FDA memo signaled tougher vaccine approval standards, just as an activist shareholder ramps up pressure for a potential sale of the company.

See our latest analysis for Novavax.

Those cross-currents help explain why, at a share price of $6.57, Novavax has a weak short term share price return and a deeply negative multi year total shareholder return. This suggests momentum is still fading despite flashes of optimism around milestones and deal news.

If you are weighing Novavax against other vaccine and drug makers, this could also be a good moment to explore opportunities across healthcare stocks and see how different risk reward profiles compare.

With shares down sharply over one, three, and five years but trading at a steep discount to analyst targets, is Novavax now an unloved vaccine player poised for a rebound, or is the market correctly discounting its future growth?

Most Popular Narrative: 49.9% Undervalued

Compared to Novavax's last close at $6.57, the most followed narrative sees almost double that level as fair value, hinging on a radical business-model pivot.

Ongoing cost optimization and the shift to a leaner, partnership-focused operational model (with substantial SG&A reductions and Sanofi absorbing additional costs) position Novavax for improved gross and net margins, supporting an accelerated path to sustained profitability and stronger long-term earnings.

Read the complete narrative.

Want to see what kind of shrinking revenues can still justify a richer multiple than many tech names, and why margins matter more than growth here? The key is how earnings, profit share, and a surprisingly punchy future valuation multiple work together in this narrative. Curious which specific profit and discount-rate assumptions make that upside case hang together? Dive in to decode the full playbook behind this fair value call.

Result: Fair Value of $13.11 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, this upside hinges on partners like Sanofi hitting milestones and COVID-19 demand holding up; both of these factors could easily disappoint.
