But with shares already vaulting higher and fresh clinical catalysts on the horizon, investors now face a crucial question: is there still a window for upside, or is the stock’s future potential already reflected in its price?

Most Popular Narrative: 43.8% Undervalued

According to the most popular narrative, Nektar Therapeutics' fair value stands at $101.17, which is substantially above the most recent closing price of $56.89. This sharp valuation divide pivots on the huge commercial opportunity tied to rezpegaldesleukin and its clinical trajectory.

Strong initial Phase IIb and ongoing data for REZPEG in atopic dermatitis, combined with a large and growing addressable market (expected to reach nearly $30B by 2033), position Nektar to access significant new revenue streams and improve long-term earnings as the population ages and chronic inflammatory diseases rise globally. FDA Fast Track designation for REZPEG in both atopic dermatitis and alopecia areata gives Nektar an accelerated regulatory path, potentially reducing time to market and R&D costs, which should improve net margins and cash flow if approvals are achieved ahead of competitors.
