Approach 1: Inspire Medical Systems Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow, or DCF, model estimates what a company might be worth by projecting its future cash flows and then discounting those back to today’s value. In this case, the model used is a 2 Stage Free Cash Flow to Equity approach.

Inspire Medical Systems is currently generating trailing twelve month free cash flow of about US$96.3 million. Based on analyst inputs and extrapolations by Simply Wall St, projected free cash flow is US$132.0 million in 2030, with intermediate estimates such as US$165.95 million for 2026 and US$206.0 million for 2027. All of these cash flows are in US dollars and are discounted back to the present to arrive at an estimated intrinsic value per share.

On this basis, the DCF model suggests a fair value of roughly US$69.67 per share. Compared with the recent share price of about US$94, this implies the stock is 35.6% above the DCF estimate, which indicates it is overvalued under these cash flow assumptions.

Result: OVERVALUED

Approach 2: Inspire Medical Systems Price vs Earnings

For a profitable company, the P/E ratio is a simple way to connect what you pay for each share with the earnings that support it. It gives you a quick sense of how many dollars investors are willing to pay today for one dollar of current earnings.

What counts as a “normal” P/E depends on how the market views growth potential and risk. Higher expected growth or lower perceived risk can support a higher P/E, while lower growth expectations or higher risk usually point to a lower multiple.

Inspire Medical Systems is currently trading on a P/E of about 61.6x. That is close to the peer average of 60.8x and well above the Medical Equipment industry average of 31.4x. Simply Wall St’s Fair Ratio for Inspire Medical Systems is 24.4x, which reflects a proprietary model that looks at earnings growth, profit margins, size, industry and company specific risks.

This Fair Ratio can be more informative than a simple peer or industry comparison because it tailors the expected P/E to the company’s own profile rather than assuming that all medical equipment stocks deserve similar multiples. Comparing the current P/E of 61.6x to the Fair Ratio of 24.4x suggests the shares trade above what this model would imply.

Result: OVERVALUED
