Most Popular Narrative: 31.7% Undervalued

Catalyst Pharmaceuticals' most popular narrative places fair value significantly above the last close, suggesting a notable disconnect between recent trading levels and what the broader narrative expects for future performance. With analysts factoring in robust growth drivers, the rationale behind these expectations is important for understanding the potential upside.

Significant upside exists from expanding FIRDAPSE's addressable patient pool by improving rare cancer-associated LEMS diagnosis, driven by updated NCCN guidelines, wider access to frictionless VGCC antibody testing, and targeted oncology education. With 90% of this segment still undiagnosed, this lays a foundation for sustained, above-market revenue growth in 2026 and beyond as more patients are identified and treated.
