What Is Biohaven's Investment Narrative?

To own Biohaven, you really have to believe its antibody‑targeting MoDE and TRAP degrader platforms can turn today’s zero‑revenue, high‑cash‑burn profile into a viable portfolio of immune, neuro and metabolic therapies. The latest IgA nephropathy and Graves’ disease data feed directly into that story, because they move BHV‑1400 and BHV‑1300 from early mechanistic promise toward clinically observed patient benefit and create a clearer path to pivotal trials, which now look like key short term catalysts alongside updates in Parkinson’s and obesity. The strong share price reaction suggests this news is being treated as material, but it does not erase core risks: Biohaven is still loss‑making, has negative equity, has diluted shareholders and faces securities litigation and trial‑execution uncertainty. The stakes around future data readouts just got higher.

However, there is an important financing and dilution risk here that investors should be aware of. The valuation report we've compiled suggests that Biohaven's current price could be inflated.
