Most Popular Narrative: 13.6% Undervalued

According to the most widely followed narrative, Rhythm Pharmaceuticals’ fair value is estimated at $126.31, which stands notably above the recent closing price of $109.09. This setup reflects high expectations for the company’s growth trajectory and the market-shaping catalysts anticipated on the horizon.

Upcoming potential regulatory approvals and launches for setmelanotide (IMCIVREE) in new indications such as acquired hypothalamic obesity and Prader-Willi syndrome, along with expansion into younger age groups, are expected to materially grow Rhythm's commercial opportunity and topline in the next several years. Extension of intellectual property protection to 2034 for the lead asset and to 2040 and beyond for next-generation compounds, combined with orphan drug exclusivity incentives in the U.S. and EU, create a multi-year window of strong pricing power and high net margins. This protects earnings from generic and biosimilar erosion.
