Weak moat
How hard Cartesian Therapeutics's competitive advantage looks for rivals to wear away, judged from 10 years of its own filings: returns on capital, pricing power, profit durability, cash conversion and discipline.
Net income has been a median -46.4% of total assets over 10 years.
Operating margin has been a median -1075.1%; its worst year was -153893.2%.
Free cash flow was positive in 1 of 10 years, at a median -707.0% of revenue.
The diluted share count rose 1018.4% over five years; stock-based pay has been a median 78.0% of revenue.
