Rhythm Pharmaceuticals (RYTM): Assessing Valuation Following Phase 3 Setmelanotide Results and Pipeline Advances

Rhythm Pharmaceuticals (RYTM) just turned heads with a one-two punch of major news. The company announced positive phase 3 results for its drug setmelanotide, targeting obesity caused by hypothalamic damage, and followed this up by submitting regulatory applications for label expansion. As if that were not enough, Rhythm also revealed it is pushing another promising candidate, bivamelagon, into phase 3 studies early next year. These updates send a clear message that Rhythm is stepping up its game in the competitive weight management space. Over the past year, Rhythm shares have returned an impressive 88%, reinforcing optimism from investors and hinting at buzz around its expanding pipeline. The stock’s 51% climb in the past three months suggests momentum is building, likely fueled by this fresh batch of clinical and regulatory milestones. Compared to its long-term track record and recent financial growth, including a 44% bump in annual revenue and significant improvement in net income, Rhythm seems to be gaining traction at a critical time in the obesity treatment market. With the stock powering higher on clinical good news and future possibilities, the crucial question is whether Rhythm’s current price leaves room for further gains or if the market is already factoring in the next leg of growth.

Most Popular Narrative: 14.6% Undervalued

The prevailing narrative suggests that Rhythm Pharmaceuticals is currently undervalued by a notable margin, despite recent share price momentum and high growth expectations.

Extension of intellectual property protection to 2034 for the lead asset and to 2040 and beyond for next-generation compounds, along with orphan drug exclusivity incentives in the U.S. and EU, create a multi-year window of strong pricing power and high net margins. These protections shield earnings from generic and biosimilar erosion.
