The price needs 34.8% growth a year for ten years. The AI thinks 20.0% is achievable, at a 24.8% margin.

Insmed looks roughly fairly priced: the market already pays for a very successful launch of its new lung drug BRINSUPRI and a decent chance that its inhaled pulmonary hypertension drug TPIP works. Revenue grew from $142M to $524M per quarter in a year, and losses are shrinking quickly as sales outrun costs. Management sees $14B+ of combined peak sales, but even haircutting that, the stock price assumes most of it happens. The main risk is a binary one: TPIP trials failing or BRINSUPRI demand plateauing once the initial patient backlog is treated would leave a rich valuation exposed.

In addition, the company is developing treprostinil palmitil inhalation powder, an inhaled formulation of a treprostinil prodrug treprostinil palmitil, which is in phase 3 clinical trial for the treatment of pulmonary hypertension associated with interstitial lung disease; and phase 2 clinical trial for the treatment of pulmonary arterial hypertension. Further, it develops INS1201, a microdystrophin adeno-associated virus gene replacement therapy which is in phase 1 clinical trial for the treatment of Duchenne muscular dystrophy, as well as it is also developing pre-clinical research programs for gene therapy, AI-driven protein engineering, protein manufacturing, RNA end-joining, and synthetic rescue. In addition, it provides INS1148, monoclonal antibody targeting stem cell factor called SCF248 that is in phase-2 clinical trial for the treatment of interstitial lung disease, and asthma; and INS1202, an intrathecally delivered gene therapy which is in phase 1 of clinical trial for the treatment of amyotrophic lateral sclerosis.
