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

A Discounted Cash Flow model takes estimates of the cash a company might generate in the future and discounts those figures back to today, aiming to arrive at an estimate of what the entire business could be worth now.

For Syndax Pharmaceuticals, the model used is a 2 Stage Free Cash Flow to Equity approach, based on cash flow projections in $. The latest twelve month free cash flow is a loss of about $311.2 million. Analysts provide explicit forecasts for the next few years, and Simply Wall St then extends those estimates further out. In this case, projected free cash flow for 2030 is about $424.8 million, with interim years gradually moving from negative to positive territory as shown in the ten year projections.

When all those future cash flows are discounted back and summed, the model arrives at an estimated intrinsic value of about $125.82 per share. Compared with the recent share price of US$21.71, this implies an intrinsic discount of roughly 82.7%, suggesting that the shares appear heavily undervalued on this model.

Approach 2: Syndax Pharmaceuticals Price vs Sales

For companies that are not yet profitable, the P/S ratio is often more useful than P/E because it compares the share price with current revenues rather than earnings that may still be negative. It gives you a quick sense of how much investors are paying for each dollar of sales.

What counts as a “normal” P/S ratio usually reflects what investors think about the company’s growth potential and risk profile. Higher expected growth and lower perceived risk tend to support a higher P/S, while slower growth or higher uncertainty often come with a lower multiple.

Syndax Pharmaceuticals currently trades on a P/S of 16.95x, compared with the Biotechs industry average of about 11.64x and a peer average of 11.71x. Simply Wall St’s proprietary Fair Ratio for Syndax is 1.04x. The Fair Ratio is designed to be a more tailored benchmark than a simple peer or industry comparison because it factors in elements such as growth expectations, risks, profit margins, market cap and the company’s industry.

With the actual P/S of 16.95x well above the Fair Ratio of 1.04x, this framework suggests the shares are trading on a richer multiple than those fundamentals would typically support.
