What to look at in Healthcare / Pharma
The R&D pipeline is the invisible asset. Patents expiring = revenues evaporating. Look at innovation and cash flow.
- R&D / Revenue — Shows investment in future pipeline. Serious pharma reinvests 15-20%
- 5y EPS growth — After patent expirations, are they still growing?
- Gross margin — Branded pharma >70%. Generics much lower — defines the business type
- FCF / Net Income — Earnings quality — big pharma should convert >90%
- ROIC — Capital reinvested efficiently — key in pharma due to long R&D cycles
- Net debt / EBITDA — Pharma acquisitions pile up debt — watch the post-M&A picture
- P/E vs own 10y history — The best comparison is with its own history, not with peers
