Acadia Pharmaceuticals (ACAD) After Patent And RADIANT Updates Is The Undervalued View Too Simple

Simply Wall St·10/06/2026 07:14:18
Listen to the news

Acadia Pharmaceuticals (ACAD) just picked up two important pipeline milestones. Fresh US patent protection for Rett therapy trofinetide and Phase 2 RADIANT data for remlifanserin are now in focus for anyone tracking the stock.

Despite this twin pipeline update, Acadia Pharmaceuticals’ share price has fallen about 28% over the past month and about 23% year to date, while the 1-year total shareholder return is down roughly 7%. This suggests that recent news is being weighed against longer term execution and risk around late stage trials.

Acadia Pharmaceuticals now trades well below the average analyst target despite fresh IP and late stage trial momentum. Is this a simple valuation discount, or a clear warning that pipeline risk still dominates the story?

Most Popular Narrative: 37.5% Undervalued

Acadia Pharmaceuticals closed at $20.11, while the most followed narrative pegs fair value at $32.16 using a 7.55% discount rate. The gap between those numbers rests heavily on how investors view the core brands and the dementia psychosis pipeline.

The main thing that has to go right is successful execution on DAYBUE lifecycle expansion and remlifanserin development, including EU and Japan rollout for trofinetide and an effective Phase III program after the mixed but directionally positive RADIANT Phase II readout.

See why 56 investors see Acadia Pharmaceuticals as 37% undervalued.

Result: Fair Value of $32.16 (UNDERVALUED)

Still, Acadia Pharmaceuticals faces two clear pressure points: remlifanserin trial uncertainty after RADIANT, and the heavy reliance on DAYBUE and NUPLAZID hitting ambitious sales targets.
