1. Increasing Number of Domestic Medical Centers Leads to More Shots On Goal
Sales growth for companies like Inspire Medical Systems can be broken down into the number of facilities/providers and the revenue for each. While both are important, the latter is the lifeblood of a successful Medical Devices & Supplies - Specialty company because there’s a ceiling to how many facilities and providers one can secure.
Inspire Medical Systems’s number of domestic medical centers punched in at 1,524 in the latest quarter, and over the last two years, averaged 24.5% year-on-year growth. This pace was fast and gives the company more opportunities to increase its revenue. 
2. Outstanding Long-Term EPS Growth
Analyzing the long-term change in earnings per share (EPS) shows whether a company's incremental sales were profitable – for example, revenue could be inflated through excessive spending on advertising and promotions.
Inspire Medical Systems’s full-year EPS flipped from negative to positive over the last five years. This is a good sign and shows it’s at an inflection point.
3. Increasing Free Cash Flow Margin Juices Financials
If you’ve followed StockStory for a while, you know we emphasize free cash flow. Why, you ask? We believe that in the end, cash is king, and you can’t use accounting profits to pay the bills.
As you can see below, Inspire Medical Systems’s margin expanded by 31.8 percentage points over the last five years. The company’s improvement shows it’s heading in the right direction, and we can see it became a less capital-intensive business because its free cash flow profitability rose more than its operating profitability. Inspire Medical Systems’s free cash flow margin for the trailing 12 months was 9.9%.
Final Judgment
These are just a few reasons why we think Inspire Medical Systems is a high-quality business. After the recent drawdown, the stock trades at 102.9× forward P/E (or $83 per share).
