• On Simply Wall St's 6 point value check, Catalyst Pharmaceuticals currently scores a 6 out of 6 valuation score. The next sections break that down using multiple valuation approaches before finishing with a broader way to think about what valuation means for your investment case.

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

A Discounted Cash Flow model takes estimates of a company’s future cash flows, discounts them back to today using a required return, and sums them to arrive at an estimate of what the business could be worth per share right now.

For Catalyst Pharmaceuticals, the model used is a 2 Stage Free Cash Flow to Equity approach based on cash flow projections. The latest twelve month free cash flow is about $129.4 million, and analysts supply explicit forecasts out to 2027, with Simply Wall St extrapolating further. Those projections show free cash flow reaching an estimated $340.0 million in 2030, all expressed in $.

Discounting the projected cash flows produces an estimated intrinsic value of $63.32 per share. Against a recent share price around $24.94, this implies an intrinsic discount of 60.6%, which indicates that the shares are trading well below this DCF estimate.

Result: UNDERVALUED

Our Discounted Cash Flow (DCF) analysis suggests Catalyst Pharmaceuticals is undervalued by 60.6%. Track this in your watchlist or portfolio, or discover 58 more high quality undervalued stocks.

Approach 2: Catalyst Pharmaceuticals Price vs Earnings

For profitable companies, the P/E ratio is a useful way to think about what the market is paying for each dollar of earnings. A higher P/E usually reflects higher growth expectations or lower perceived risk, while a lower P/E can signal more modest growth expectations or higher perceived risk. There is no single “right” P/E; the context matters.

Catalyst Pharmaceuticals currently trades on a P/E of 14.21x. That sits below the Biotechs industry average of 17.55x and also below the peer average of 29.22x. Simply Wall St’s Fair Ratio for Catalyst is 14.88x, which reflects what its P/E might be given factors such as earnings growth, industry, profit margins, market cap and company specific risks.

The Fair Ratio is more tailored than a simple comparison with industry or peer averages because it adjusts for company specific characteristics rather than assuming all Biotechs should trade on the same multiple. Comparing Catalyst’s current P/E of 14.21x with the Fair Ratio of 14.88x suggests the shares are modestly undervalued on this metric.

Result: UNDERVALUED

Upgrade Your Decision Making: Choose your Catalyst Pharmaceuticals Narrative

Earlier the idea came up that there is an even better way to think about valuation, so Narratives give you a simple story for Catalyst Pharmaceuticals that ties your view on its rare disease portfolio, future revenue, earnings and margins to a financial forecast and fair value. It sits inside the Simply Wall St Community page, updates automatically when new news or earnings arrive, and lets two investors reach very different yet structured conclusions. For example, one Narrative may lean toward the higher US$40.00 fair value because it assumes stronger product expansion and durable margins, while another may lean toward the lower US$31.00 fair value because it places more weight on concentration, patent and generic risks. Each investor can then compare their chosen fair value with the current share price to decide whether the stock fits their own buy, hold or sell plan.
