atai Life Sciences Announces Closing of Public Offering and Full Exercise of Option to Purchase Additional Common Shares
NEW YORK and AMSTERDAM, Oct. 20, 2025 (GLOBE NEWSWIRE) -- atai Life Sciences (NASDAQ:ATAI) ("atai"), a clinical-stage biopharmaceutical company focused on transforming the treatment of mental health disorders, today announced that, on October 20, 2025, the closing of its public offering of 27,283,750 common shares occurred, inclusive of the closing of the underwriters' option in full to purchase an additional 3,558,750 common shares at the public offering price of $5.48 per share following the exercise by the underwriters of their option on October 17, 2025. The aggregate gross proceeds from the offering, including the gross proceeds from the exercise of the underwriters' option to purchase additional shares, were approximately $149.5 million, before deducting underwriting discounts and commissions and other offering expenses payable by atai.
The financing included participation from new investors Janus Henderson Investors, Foresite Capital, Deep Track Capital, and HBM Partners alongside existing investors including Ferring Ventures, Columbia Threadneedle Investments, Ally Bridge Group, Woodline Partners LP, and ADAR1 Capital Management, as well as new and existing large investment management firms.
atai intends to use the net proceeds from the offering, together with existing cash, cash equivalents, short-term investments and other liquid assets, to advance the clinical development across its pipeline of product candidates and programs. This includes funding the planned Phase 3 clinical program for BPL-003 (mebufotenin benzoate) nasal spray through the top-line data readout from the first Phase 3 clinical trial, completing the Phase 2 clinical trial of VLS-01 (buccal film DMT), and completing the Phase 2a study for EMP-01 (oral R-MDMA), as well as for working capital and general corporate purposes. Based on this planned use of proceeds and atai's current operating plan, atai estimates that its existing cash, cash equivalents, short-term investments and other liquid assets will be sufficient to fund operations into 2029.
Christian Angermayer, Founder and Chairman of atai, commented: "We are deeply grateful for the strong and continued validation of our mission that this successful financing represents. The commitment from both our distinguished existing and new, predominantly healthcare-focused institutional investors reflects their confidence in atai's pipeline and long-term vision. I believe psychedelics have the potential to fundamentally redefine the treatment landscape for mental health disorders, and we remain steadfast in our mission to bring these transformative therapeutics to patients as swiftly as possible. They deserve nothing less."
