Find out why Vertex Pharmaceuticals's -15.6% return over the last year is lagging behind its peers.

Approach 1: Vertex Pharmaceuticals Discounted Cash Flow (DCF) Analysis

The Discounted Cash Flow (DCF) model seeks to estimate a company's intrinsic value by projecting its future cash flows and discounting them back to today's value. This method is widely used because it attempts to capture both current performance and growth potential over time.

For Vertex Pharmaceuticals, the latest reported Free Cash Flow stands at $3.46 billion. Analyst estimates and model extrapolations suggest this figure could climb to around $6.61 billion by 2029, with cash flow growth supported by product pipeline advances and expanded market opportunities. The ten-year outlook, which combines analyst forecasts for the next five years with longer-term projections, demonstrates a consistent increase in expected annual cash flows.

Based on the DCF analysis, Vertex's estimated intrinsic value comes out to $701.98 per share. This figure is nearly 40 percent higher than the company's current share price, indicating a significant margin of safety.

In summary, the DCF approach signals that Vertex shares are currently undervalued by 39.9 percent, giving value-focused investors a clear reason to pay attention.

Approach 2: Vertex Pharmaceuticals Price vs Earnings

The Price-to-Earnings (PE) ratio is widely used to assess the value of profitable companies because it reflects what investors are willing to pay for each dollar of a company's earnings. It is especially relevant for mature businesses like Vertex Pharmaceuticals that generate consistent profits, as it ties the stock price directly to underlying earnings power.

A higher PE ratio can be justified when a company has strong growth expectations or presents lower risk, while a lower PE often reflects investor caution or slower growth prospects. For Vertex, the current PE ratio sits at 29.1x. This is notably higher than the Biotechs industry average of 17.0x but lower than the peer group average of 54.9x, highlighting Vertex's solid position in the sector.

To add further context, Simply Wall St's proprietary "Fair Ratio" considers key aspects such as Vertex’s earnings growth, profit margins, market cap, and risks. This approach blends these factors with usual industry measures to deliver a more tailored benchmark than a broad industry average or single-company peer, as it reflects both company-specific qualities and wider market conditions.

In Vertex’s case, the Fair Ratio is calculated at 29.0x, nearly identical to its actual PE ratio of 29.1x. This suggests that the current share price is aligned with its projected growth, profitability, and risk profile.

Upgrade Your Decision Making: Choose your Vertex Pharmaceuticals Narrative

Earlier we mentioned that there is an even better way to understand valuation, so let’s introduce you to Narratives, a smarter and more flexible tool that lets investors tell the story behind the numbers and shape their own view of a company’s value.

A Narrative is your personal investment perspective. It links the developments, catalysts, and risks you see for a business like Vertex Pharmaceuticals directly to specific financial forecasts and a resulting fair value. Rather than relying only on static metrics or analyst targets, Narratives empower you to document your expectations for revenue growth, margins, and earnings, and then see how these assumptions translate to a fair price per share.

Narratives are easy to use on Simply Wall St’s Community page and are leveraged by millions of investors, allowing you to compare your own outlook and valuation with others. When company news, earnings, or market conditions shift, Narratives update instantly, keeping your conclusions fresh and relevant.

For example, some investors may be optimistic, seeing strong gene editing launches and robust global sales as justification for a fair value near $616 per share. More cautious investors may see pipeline risks and industry pressures supporting a lower fair value closer to $330 per share. Narratives help you visualize these diverse viewpoints so you can decide if, when, and why it’s time to buy or sell.
