Healing mental health disorders so that everyone everywhere can live a more fulfilled life

Corporate Presentation - March 2025

Significant unmet need: mental health disorders are one of the largest global health burdens; it is estimated that one out of every two people in the world will develop a mental health disorder in their lifetime1

5 clinical-stageprograms: four psychedelic programs and one non-psychedelic program; our psychedelic programs focus on leveraging the "2-hour treatment window" pioneered by Spravato®

Multiple Phase 2 readouts expected over the next 12 months: several anticipated clinical trial readouts across our

drug development programs and strategic investments

Runway into 2027: cash and cash equivalents, marketable securities, and committed term loan funding expected to provide funding into 20272

05

Our vision is being delivered through a robust pipeline of clinical-stage programs across a range of compounds and psychiatric indications

Predictable 2-hour treatment: the potential to fit into the 2-hour in-clinictreatment paradigm established by Spravato

Established infrastructure and reimbursement: potential to

immediately leverage Spravato's reimbursement pathways and >4,500 certified clinics2

Extended durability reduces patient burden: 1-2doses of a psychedelic

therapy provides a sustained effect, simplifying the dosing schedule compared to esketamine's once-weekly regimen

Significantly improves use of infrastructure: lower dosing frequency compared to esketamine will lower provider burden, and improve payer receptivity

(Buccal Film DMT) for

TRD

SUMMARY:VLS-01 (buccalVLS-01film DMT) is a patent-protected formulation, designed to fit into established ~2-hourinterventional psychiatry treatment paradigm for TRD

Optimized transmucosal buccal film formulation: Phase 1 study demonstrated favorable safety & tolerability and an IV-like PK profile, which may support a more scalable patient / provider experience

Short duration psychedelic effect: Phase 1 data suggests subjective effects experienced for ~2 hours, potentially enabling VLS-01 to fit into interventional psychiatry paradigm established by Spravato®

Potential for rapid onset and durable efficacy: Prior clinical evidence with DMT has generated sustained, clinically meaningful improvement on depressive symptoms1

Patent protected formulation: Issued patents and pending applications covering compositions and methods of use (expiry anticipated 20422)

Abbreviations: DMT = N,N-Dimethyltryptamine; TRD= Treatment Resistant Depression; PK = Pharmacokinetic;
