Why Amylyx Pharmaceuticals (AMLX) Is Back In The Spotlight

Amylyx Pharmaceuticals (AMLX) has secured long-term manufacturing arrangements for its avexitide drug substance through a new agreement with Bachem Americas and a term sheet with Polypeptide Group.

Most Popular Narrative: 25.6% Overvalued

At a last close of $32.09 against a narrative fair value of $25.56, Amylyx Pharmaceuticals is framed as ahead of that central valuation, with the story hinging on one core clinical readout and its ripple effects on future cash flows.

The company is targeting post bariatric hypoglycemia, a condition with no FDA approved therapies and an estimated 160,000 patients in the U.S., which creates room for a first approved product like avexitide to establish a new revenue line if pricing and access are secured.

Another View on Amylyx Pharmaceuticals Valuation

While the analyst narrative frames Amylyx Pharmaceuticals as 25.6% overvalued at $32.09 versus a $25.56 fair value, the SWS DCF model points in the opposite direction. On that cash flow view, AMLX is priced at a steep discount, with the shares trading 84.1% below a DCF estimate of $201.25.
