COMPASS Pathways is offering $150,000,000 of American Depositary Shares and pre-funded warrants in a primary equity raise, plus ADSs issuable on warrant exercise. Underwriters also have a 30-day option to buy up to an additional $22.5 million of ADSs. Net proceeds are earmarked mainly to fund COMP360 Phase 3 trials in treatment-resistant depression, a Phase 2b/3 PTSD trial, and commercial launch preparation, alongside general corporate uses.
The company recently reported that both pivotal Phase 3 trials, COMP005 and COMP006, met their primary endpoints, with 25 mg COMP360 showing highly statistically significant and clinically meaningful MADRS improvements versus control and a generally well-tolerated safety profile. Preliminary cash and cash equivalents were about $149.6 million as of December 31, 2025, and management warns that without this or similar financing there is substantial doubt about the ability to continue as a going concern.

Compass Pathways reported strongly positive topline results from both pivotal Phase 3 trials of its COMP360 psilocybin treatment for treatment‑resistant depression. In COMP005, a single 25 mg dose showed a highly statistically significant mean MADRS improvement versus placebo of -3.6 points at Week 6 (p<0.001), with rapid onset from the day after dosing and durability out to Week 26 for many responders. In COMP006, two 25 mg doses given three weeks apart achieved a -3.8‑point difference versus 1 mg at Week 6 (p<0.001), with 39% of patients reaching a clinically meaningful ≥25% MADRS reduction. Across more than 800 treated patients in these Phase 3 arms, COMP360 was generally well-tolerated; most adverse events such as headache, nausea, anxiety and visual hallucinations occurred on dosing days and resolved within a day, and serious suicidal events were rare and mainly in lower‑dose or control arms. The company plans to meet the FDA to discuss rolling NDA submission and expects to complete an NDA for COMP360 in Q4, supported by Breakthrough Therapy designation.
