Fundamental quality

out of 100
Biogen Inc. runs like a cash machine: it converts about 24.4% of revenue into free cash flow and holds a 13.8% net margin, though it grows at a measured pace. On fundamental quality it scores 54 out of 100, profiling it as a company with demanding fundamentals. Its weakest area is its growth (revenue -5.6%/yr). Whether it's cheap or expensive depends on the current price, which you can compute in the tool.
Biogen is one of the veteran biotechs, specialized in nervous-system diseases: multiple sclerosis, spinal muscular atrophy and the riskiest bet of all, Alzheimer's. It lives the classic pharma dilemma: mature franchises in decline and a new generation that needs to work.
