Pfizer (PFE) Valuation in Focus Following FDA Approval of Updated COVID-19 Vaccine

Kshitija Bhandaru

Pfizer (PFE) just landed a significant regulatory win. On August 27, the company and its partner BioNTech announced that the U.S. Food and Drug Administration approved their updated LP.8.1-adapted monovalent COVID-19 vaccine. This new version is cleared for adults aged 65 and over, as well as younger high-risk individuals, thanks to clinical data showing it provides stronger immune protection against multiple newer COVID strains. For investors wondering where this leaves Pfizer as COVID revenue stabilizes, this FDA nod keeps the company’s vaccine business in the spotlight and could open the door to more recurring demand in the higher-risk population.

Looking at the bigger picture, the news comes at an interesting moment for Pfizer’s stock. Over the past year, shares fell about 6%, but recent weeks have seen a bit of momentum with gains of 5% in the past month and almost 6% over the past 3 months. This turnaround follows a tough period marked by falling COVID product sales and challenges like major patent expirations looming from 2026 onward. However, Pfizer's expanded vaccine approvals and continued work in oncology suggest that new catalysts may be on deck as the company remakes its product lineup.

So, after this year’s mixed performance and fresh regulatory tailwinds, the real question is whether Pfizer is now trading at a bargain or if investors should be cautious about how much future growth is already built into the share price.

Most Popular Narrative: 19.1% Undervalued

According to a widely followed narrative, Pfizer’s current share price is seen as offering a solid discount to its fair value, reflecting optimism about the company's transition beyond Covid-related products.

I think that Pfizer has a strong pipeline. The acquisition of Seagen added many new oncology products that will continue to grow by 14%, partially offsetting the decline in sales of the Covid-19 vaccines. This should keep revenue flat, possibly growing in low to mid single digits in an optimistic scenario.

Curious how this fair value was calculated? The most bullish assumptions in this narrative point to operational margin strength and future product launches well above market expectations. What are the numbers behind this confidence? Discover which variables could supercharge Pfizer's valuation and why the growth forecast might surprise you.

Result: Fair Value of $30.62 (UNDERVALUED)

However, still, stubbornly high debt levels and the possibility of a dividend cut could challenge the case for Pfizer’s undervaluation in the near term.
