Moderna (MRNA): Assessing Valuation Following Strong Clinical Data and Regulatory Wins for Updated Spikevax Vaccine

Moderna (MRNA) is in the spotlight following its announcement of strong new clinical data for the updated Spikevax COVID-19 vaccine, specifically targeting the LP.8.1 variant. According to the company, the new formulation generated an 8-fold increase in neutralizing antibodies in high-risk groups, spanning both younger adults with risk factors and all adults over 65. Backed by FDA approval for expanded use, as well as regulatory green lights in several international markets, these results have sparked fresh debate about the stock's future path.

This latest news lands at a time when investor interest in Moderna is reawakening, even as its share price continues to reflect broad skepticism. Over the past year, the stock has fallen 64% and is down 41% year-to-date, a sharp contrast to its earlier pandemic-driven growth story. Despite the meaningful bump from the recent vaccine update, momentum has struggled to build as the market weighs new opportunities in mRNA technology against ongoing financial losses and growing competition, particularly with BioNTech’s push into cancer immunotherapy and emerging biotech players securing fresh capital.

Given the divergence between strong clinical advancements and the trajectory of the stock, is Moderna a bargain for investors at this level, or is the current price already baking in its growth prospects?

Most Popular Narrative: 85.8% Undervalued

According to the most popular narrative, Moderna may be significantly undervalued given the scale of its innovative investments and its transition beyond COVID-19 vaccines.

Despite the defunding of US governmental research and health services, Moderna remains in a commanding fundamental position. The company that made its name during the COVID-19 pandemic developing and manufacturing vaccines for the disease at breakneck pace also happened to have bagged a historic windfall in exchange for its performance. Less well-known is how Moderna reinvested the windfall in the wake of its success. The company has spent years plowing its profits into new innovations while maintaining a relatively pristine balance sheet for a company as large as it is.

Something big might be brewing beneath the surface at Moderna. The narrative points to a pipeline packed with potential and a transition phase that could reset the company’s place in biotech. Wondering how aggressive revenue growth and margin assumptions shape this sky-high valuation? The full breakdown reveals what makes this undervalued story stand out in a crowded sector.
