Business Highlights

COMP360 psilocybin treatment in TRD (Treatment Resistant Depression)

• The pivotal phase 3 clinical program of COMP360 psilocybin treatment in TRD is the largest-to-date randomized, controlled, double-blind psilocybin treatment clinical program.
• All participants have completed dosing in part A of the COMP005 phase 3 trial for TRD and top-line 6-week (primary endpoint) data are expected in late June.
• 26-week COMP005 data is expected once all participants in the COMP006 trial have completed part A of the COMP006 trial.
• COMP006 26-week data is expected in the second half of 2026.
• Recent 52-week data from an observational follow-up study published on COMP360 demonstrated a durable treatment response and a median time to depressive event of 92 days (n=252) on a single 25mg administration and 189 days (n=58) for the 25mg subgroup that continued into the COMP004 long-term extension

COMP360 psilocybin treatment in PTSD (Post Traumatic Stress Disorder)

• Company designing late-stage clinical trial program
• Phase 2 open label 12-week safety and tolerability study (n=22) announced in May 2024, showed COMP360 was well tolerated and demonstrated both rapid and durable improvement in symptoms from baseline observed following a single administration.

Financial highlights

• Net loss for the three months ended March 31, 2025, was $17.9 million, or $0.20 net loss per share: basic, $0.24 net loss per share: diluted, compared with $35.2 million, or $0.55 loss per share basic and diluted, during the same period in 2024. The decrease in net loss for the quarter was primarily driven by a $19.5 million non-cash gain on fair value adjustment related to our warrant liabilities. As the fair value of the warrants fluctuates with our share price and other market inputs, this adjustment can result in significant variability in our reported net loss.

• Non-cash share-based compensation for the three months ended March 31, 2025 was $3.9 million compared with $5.1 million for the same period in 2024.

• Research and development expenses were $30.9 million for the three months ended March 31, 2025, compared with $24.9 million during the same period in 2024. The increase was primarily attributable to development expenses associated with advancing our late-stage COMP360 phase 3 clinical trials partially offset by decreased personnel and non-cash share-based compensation expenses due to decreased staffing levels associated with the strategic reorganization that took place in the fourth quarter of 2024.

• General and administrative expenses were $18.7 million for the three months ended March 31, 2025, compared with $13.7 million during the same period in 2024. The increase was primarily attributable to issuance costs related to the 2025 Financing as well as expenses associated with consulting, accounting and legal advice.

• Gain on change in fair value of warrants for the three months ended March 31, 2025, was $19.5 million compared with $0.0 million during the same period in 2024.

• Cash and cash equivalents were $260.1 million as of March 31, 2025, compared with $165.1 million as of December 31, 2024.

• An additional $140.4 million net cash raised in the first quarter of 2025.

Financial Guidance

Full year 2025 net cash used in operating activities is expected to be in the range of $120 million to $145 million. The cash position at March 31, 2025 is expected to be sufficient to fund operating expenses and capital expenditure requirements at least through the planned 26-week data read-out from the COMP006 study, which is expected in the second half of 2026.

Conference call

The management team will host a conference call at 8:00 am ET (1:00 pm UK) on May 8, 2025. A live webcast of the call will be available on the Compass Pathways website at First Quarter 2025 Financial Results.
