Key Dates

Recommendation

While Denali Therapeutics shows significant clinical progress with multiple programs advancing and a key PDUFA date approaching, the increasing net losses and R&D/G&A expenses indicate continued cash burn. The recent capital raises provide a strong cash runway, but the stock's performance will heavily depend on successful regulatory approvals and commercialization, making it a "Hold" for now, awaiting further definitive clinical and regulatory outcomes.
