Moderna’s stock price has taken a beating over the past six months, shedding 33.6% of its value and falling to $26.85 per share. This was partly due to its softer quarterly results and may have investors wondering how to approach the situation.

Why Do We Think Moderna Will Underperform?
Even with the cheaper entry price, we're sitting this one out for now. Here are three reasons why there are better opportunities than MRNA and a stock we'd rather own.
1. Revenue Tumbling Downwards
We at StockStory place the most emphasis on long-term growth, but within healthcare, a stretched historical view may miss recent innovations or disruptive industry trends. Moderna’s recent performance marks a sharp pivot from its five-year trend as its revenue has shown annualized declines of 54.1% over the last two years.
2. Free Cash Flow Margin Dropping
Free cash flow isn't a prominently featured metric in company financials and earnings releases, but we think it's telling because it accounts for all operating and capital expenses, making it tough to manipulate. Cash is king.
As you can see below, Moderna’s margin dropped meaningfully over the last five years. If its declines continue, it could signal increasing investment needs and capital intensity. Moderna’s free cash flow margin for the trailing 12 months was negative 127%.

3. Short Cash Runway Exposes Shareholders to Potential Dilution
As long-term investors, the risk we care about most is the permanent loss of capital, which can happen when a company goes bankrupt or raises money from a disadvantaged position. This is separate from short-term stock price volatility, something we are much less bothered by.
Moderna burned through $4.02 billion of cash over the last year. With $5.98 billion of cash on its balance sheet, the company has around 18 months of runway left (assuming its $745 million of debt isn’t due right away).

Unless the Moderna’s fundamentals change quickly, it might find itself in a position where it must raise capital from investors to continue operating. Whether that would be favorable is unclear because dilution is a headwind for shareholder returns.
We remain cautious of Moderna until it generates consistent free cash flow or any of its announced financing plans materialize on its balance sheet.
Final Judgment
We see the value of companies making people healthier, but in the case of Moderna, we’re out. Following the recent decline, the stock trades at $26.85 per share (or a forward price-to-sales ratio of 5×). The market typically values companies like Moderna based on their anticipated profits for the next 12 months, but it expects the business to lose money. We also think the upside isn’t great compared to the potential downside here - there are more exciting stocks to buy. We’d recommend looking at one of our all-time favorite software stocks.
