What does Moderna do?

Moderna is the company that made one of the two big COVID vaccines. That vaccine (Spikevax) made them billions, but as COVID fades from the headlines, investors are asking: what's next? The answer is ambitious. Moderna is using the same mRNA technology — which essentially teaches your cells to make proteins that trigger an immune response — to attack much bigger markets. Their flu vaccine could replace the old-fashioned egg-grown vaccines your doctor gives you every fall. Their combo shot would let you get both your flu and COVID vaccine in a single visit. And their cancer vaccine, developed with Merck, is perhaps the most exciting: it's custom-built for each patient's specific tumor mutations. Here's what makes Moderna interesting for investors right now: the stock is down significantly from its pandemic highs, but the pipeline has never been stronger. They have $9.5 billion in cash, they're already selling an approved RSV vaccine, and they have three potentially massive products in late-stage trials. If even two of these work, the stock has substantial upside from current levels. The risk? All of this is still unproven outside COVID. The flu market is brutally competitive. The cancer vaccine, while promising, is years from peak revenue. And Moderna burns through about $3 billion a year. This is a company with blockbuster potential but real execution risk.

What to watch

1

Flu vaccine Phase 3 results — this is the make-or-break for near-term revenue diversification. Look for superiority vs. standard flu vaccines, not just non-inferiority

2

Combo vaccine immune interference data — if combining flu and COVID antigens weakens either response, the product loses its commercial thesis

3

Q1 2026 earnings call for mRESVIA RSV commercial traction — are doctors prescribing it alongside GSK's Arexvy?

4

Cash burn trajectory — can Moderna reach cash-flow breakeven from product sales before the $9.5B war chest runs low?

5

Any updates on the personalized cancer vaccine Phase 3 enrollment pace — slow enrollment would signal commercial scalability concerns

Investment thesis

Bull case

Moderna has the most productive mRNA platform in the world, proven by Spikevax and now mRESVIA. The pipeline is stacked: a flu vaccine that could capture billions in a legacy market, a combo flu+COVID shot that would be first-in-class, and a personalized cancer vaccine that Phase 2 data suggests actually works. With $9.5B in cash and no debt pressure, they can fund all of this internally. If just the combo vaccine and cancer vaccine succeed, Moderna becomes a $100B+ company. The stock has been beaten down from pandemic highs, creating a potential entry point before multiple catalysts hit.

Bear case

Moderna is still overwhelmingly dependent on COVID vaccine revenue, which is declining year over year as pandemic urgency fades. The flu vaccine faces a brutal competitive landscape against cheap, entrenched incumbents — winning market share requires proving not just non-inferiority but meaningful superiority. The cancer vaccine is genuinely exciting but Phase 3 readouts are 12-18 months away and the manufacturing complexity of personalized vaccines could limit commercial scalability. Cash burn is real at ~$3.2B annually, and if the flu and combo trials disappoint, the stock has significant downside from here. The mRNA platform has not yet proven it can succeed outside of pandemic-driven demand.

Risk factors

COVID vaccine revenue decline continues faster than new products can replace it, pressuring cash reserves

Standalone flu vaccine fails to demonstrate superiority over existing vaccines in Phase 3, limiting commercial differentiation

Personalized cancer vaccine manufacturing proves too complex or expensive to scale beyond melanoma

Combination flu+COVID vaccine shows interference between antigens, reducing efficacy of one or both components

mRNA platform safety concerns emerge from long-term post-marketing surveillance, creating regulatory headwinds
