See how this stacks up to the rest of the Pharmaceuticals industry. <h3>Approach 1: Jazz Pharmaceuticals Discounted Cash Flow (DCF) Analysis</h3> The Discounted Cash Flow (DCF) model estimates what a company is really worth by projecting its future cash flows and discounting them back to today's dollars. For Jazz Pharmaceuticals, this method relies on two-stage free cash flow to equity projections, starting with current figures and extending up to ten years using analyst and in-house estimates. Right now, Jazz's free cash flow stands at $1.13 billion. According to analyst forecasts, this is expected to grow significantly, with free cash flow reaching an estimated $2.03 billion by 2029. Projections for the following years continue upward, with Simply Wall St extrapolating cash flows to nearly $2.57 billion by 2035. All cash flows are calculated in US dollars. Based on these forecasts, the DCF model produces an intrinsic value of $771.24 per share. This figure suggests Jazz Pharmaceuticals stock is trading at an 82.2% discount to its fair value. This indicates it is substantially undervalued compared to where it could be, based on long-term cash flow expectations. Result: UNDERVALUED Our Discounted Cash Flow (DCF) analysis suggests Jazz Pharmaceuticals is undervalued by 82.2%.

This metric tells us how much investors are willing to pay for each dollar of Jazz's sales, which is especially useful for pharmaceutical firms with fluctuating profits or non-GAAP adjustments. What counts as a “normal” or “fair” P/S ratio can depend on expectations for the company’s sales growth, profit potential, and risk profile. Higher growth or stronger margins often justify higher ratios, while more risk or uncertainty tends to bring them lower. Jazz currently trades at a P/S ratio of 2.04x. This is significantly below both the average for its industry (4.24x) and its peer group (4.31x). On the surface, this suggests Jazz may be trading at a discount relative to comparable companies in the space. However, instead of just comparing Jazz against broad averages, Simply Wall St uses a “Fair Ratio” in this case, 7.00x calculated by factoring in Jazz’s specific growth outlook, risk, margins, and market cap. This proprietary measure gives a more nuanced view, as it incorporates real company fundamentals rather than just how its peers are priced. Looking at Jazz’s current P/S of 2.04x versus its Fair Ratio of 7.00x, the stock appears considerably undervalued by this methodology, reinforcing what the DCF analysis signaled.

A Narrative is your personal take on a company's story, where you connect what you believe about Jazz Pharmaceuticals’ products, markets, and future with your assumptions for revenue, earnings, and fair value. Narratives add meaning to the numbers by linking your understanding of Jazz’s potential, such as its drug pipeline, competition, or leadership, to an actual financial forecast and valuation. This gives context to every buy or sell decision. This tool is accessible to all investors on Simply Wall St’s Community page, where millions are using Narratives to create, share, and update their perspectives visually and easily. By comparing your calculated fair value from the Narrative to today’s share price, you can see if Jazz looks like a buy, sell, or hold. As new company news or earnings are released, Narratives update automatically to reflect the latest outlook. For example, one investor might believe Jazz’s expansion in rare diseases justifies a $230 price target. A more cautious Narrative that emphasizes generic threats could put fair value at only $147, highlighting how your chosen story shapes your investment conclusions.
