To own Arrowhead, you need to believe its RNAi platform can convert late stage assets into durable commercial products, while the company manages substantial ongoing losses. REDEMPLO’s European authorisation is an important validation of plozasiran in FCS, but it does not remove the short term risk that cash burn and rising R&D and SG&A outlays continue to outpace revenue, especially with much of current income still tied to milestones and collaborations.

The most directly relevant recent announcement is Arrowhead’s Q3 2026 earnings, which showed US$75.25 million in sales but a wider net loss of US$194.28 million.

Uncover how Arrowhead Pharmaceuticals' forecasts yield a $89.08 fair value, in line with its current price.
