Compass Pathways (CMPS) said Friday it has priced an underwritten offering of about 24 million American depositary shares and pre-funded warrants at $4.275 per ADS and accompanying ADS warrant, and about $4.265 per pre-funded warrant to buy up to about 11 million ADSs and accompanying ADS warrant.

Gross proceeds from the offering, expected to close around Monday, are expected to be roughly $150 million and up to about $353 million if the ADS warrants are fully exercised, the company said.

Compass said it plans to use the net proceeds and its existing cash and cash equivalents to finance ongoing phase 3 studies in treatment-resistant depression, advance its post-traumatic stress disorder program, and for general corporate purposes.
